Item 5.  Other Events.

         On December 15, 1998, Quintiles Transnational Corp. (the "Company")
entered into an Agreement and Plan of Merger (the "Agreement") with QELS Corp.,
a Tennessee corporation and a wholly-owned subsidiary of the Company ("Merger
Sub") and ENVOY Corporation, a Tennessee corporation ("ENVOY"), which provides
for ENVOY to merge with and into Merger Sub (the "Merger") in a pooling of
interests transaction.

         Under the Agreement, each outstanding share of ENVOY common stock, par
value $0.01 per share ("ENVOY Common Stock") and each outstanding share of ENVOY
Series B Convertible Preferred Stock, liquidation preferred $10.75 per share
("ENVOY Preferred Stock") would be exchanged for 1.166 shares of Company common
stock, par value $0.01 per share ("Company Common Stock"). At December 14, 1998,
24,374,795 shares of ENVOY Common Stock and common stock equivalents were
outstanding and ENVOY had approximately 3.5 million outstanding options, which
as a result of the Merger will become exercisable for Company Common Stock. The
Merger is expected to be tax-free to ENVOY shareholders. Consummation of the
Merger is subject to certain conditions, including the approval of the Merger by
the shareholders of the Company and of ENVOY and the receipt of required
regulatory approvals, including the expiration of the applicable waiting period
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.
Prior to the meeting of the ENVOY shareholders, the Agreement may be terminated
by the Company if the Company's stock price rises above $71.50 per share or by
ENVOY if the Company's stock price falls below $40.00 per share for a specified
period. Upon completion, the Company will nominate three ENVOY members for
election to the Company's Board of Directors.

         In connection with the Agreement, the directors and holders of ENVOY
Preferred Stock (together, the "Shareholders") entered into a Stock Voting
Agreement with the Company, whereby the Shareholders agreed to vote their ENVOY
stock (constituting approximately 16% of total outstanding) in favor of the
Merger (the "Stock Voting Agreement").

         The foregoing descriptions of the Agreement and the Stock Voting
Agreement, and the transactions contemplated thereby, do not purport to be
complete and are qualified in their entirety by reference to the Agreement and
the Stock Voting Agreement, attached as exhibits hereto. A press release issued
by the Company on December 16, 1998 announcing the execution of the Agreement is
also attached hereto as Exhibit 99.02 and incorporated herein by reference.

         Section 1.3 EFFECTIVE TIME. The Merger shall become effective at the

         Section 1.5 DIRECTORS AND OFFICERS. From and after the Effective Time,
the directors of Merger Sub immediately prior to the Effective Time shall be the

Corporation or as otherwise provided by applicable Law. From and after the
Effective Time, the officers of Merger Sub immediately prior to the Effective
Time shall be the officers of the Surviving Corporation and shall hold office

                                   ARTICLE II

                              CONVERSION OF SHARES

         Section 2.1 CONVERSION OF SHARES. At the Effective Time, by virtue of
the Merger and without any action on the part of any holder of any shares of
Company Common Stock (as defined below) or any shares of capital stock of Merger
Sub:

         (a) Each share of Common Stock of the Company, no par value per share
("Company Common Stock"), issued and outstanding immediately prior to the
Effective Time (other than shares of Company Common Stock to be canceled
pursuant to Section 2.1(d) hereof) shall be converted into the right to receive
1.166 validly issued, fully paid and nonassessable shares of Common Stock of
Parent, par value $0.01 per share ("Parent Common Stock").

         (b) Each share of Series B Convertible Preferred Stock, liquidation
preference $10.75 per share ("Company Series B Preferred Stock," and together
with the Company Common Stock and the Company's Series A Convertible Preferred
Stock, no par value per share, the "Company Capital Stock"), issued and
outstanding immediately prior to the Effective Time (other than any shares of
Company Series B Preferred Stock to be canceled pursuant to Section 2.1(d)
hereof) shall be converted into the right to receive 1.166 validly issued, fully
paid and nonassessable shares of Parent Common Stock (together with the
consideration per share of Company Common Stock specified in Section 2.1(a)
above, the "Merger Consideration," and as applied to any single share of Company
Capital Stock on the basis and in the 



                                       3
<PAGE>   5

amount specified in Section 2.1(a) above and this Section 2.1(b), as the case
requires, the "Per Share Merger Consideration").

         (c) Each share of Common Stock of Merger Sub, no par value per share
("Merger Sub Common Stock"), issued and outstanding immediately prior to the
Effective Time shall be converted into one duly issued, validly authorized,
fully paid and nonassessable share of Common Stock, no par value per share, of
the Surviving Corporation.

         (d) All shares of Company Capital Stock that are owned by the Company
as treasury stock and any shares of Company Capital Stock that are owned by
Parent or Merger Sub shall automatically be canceled and retired and shall cease
to exist, and no consideration shall be delivered or deliverable in exchange
therefor.

         (e) Shares of Company Capital Stock converted pursuant to Section
2.1(a) or Section 2.1(b) shall no longer be outstanding and shall automatically
be canceled and retired and shall cease to exist, and each holder of a
certificate which immediately prior to the Effective Time represented such
outstanding shares (the "Certificates") shall cease to have any rights as
shareholders of the Company, except the right to receive the corresponding Per
Share Merger Consideration specified therein for each such share.

         (f) If between the date of this Agreement and the Effective Time, the
outstanding shares of Parent Common Stock shall have been changed into a
different number of shares or a different class by reason of any stock dividend,
subdivision, reclassification, recapitalization, split, combination or similar
transaction, or if Parent pays an extraordinary dividend or distribution, the
number of shares of Parent Common Stock to be issued in the Merger shall be
correspondingly adjusted to reflect such stock dividend, subdivision,
reclassification, recapitalization, split, combination, or similar transaction
or extraordinary dividend or distribution.

         Section 2.2 EXCHANGE PROCEDURES.

         (a) Parent shall designate a bank or trust company to act as exchange
agent hereunder (the "Exchange Agent"). From time to time as necessary after the
Effective Time, Parent shall deliver, in trust, to the Exchange Agent, for the
benefit of the holders of Certificates, for exchange in accordance with this
Article II through the Exchange Agent, certificates evidencing the shares of
Parent Common Stock issuable pursuant to Sections 2.1(a) and 2.1(b) above in
exchange for outstanding Certificates.

         (b) As soon as practicable after the Effective Time, Parent shall cause
the Exchange Agent to mail to each holder of record of Certificates (i) a form
of letter of transmittal (in customary form) specifying that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
proper delivery of the Certificates to the Exchange Agent and (ii) instructions
for use in surrendering such Certificates in exchange for the corresponding Per


                                       4
<PAGE>   6

Share Merger Consideration. Upon surrender of a Certificate for cancellation to
the Exchange Agent, together with such letter of transmittal, duly executed, and
such other documents as may be reasonably required by the Exchange Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor (A)
that number of shares of Parent Common Stock equal to the product of the
corresponding Per Share Merger Consideration multiplied by the number of shares
of Company Common Stock or Company Series B Preferred Stock (as the case
requires) represented by the surrendered Certificate, and (B) any amounts to
which the holder is entitled pursuant to Section 2.3 hereof after giving effect
to any required tax withholdings, and the Certificate so surrendered shall
forthwith be canceled. Until surrendered as contemplated by this Section 2.2(b),
each Certificate (other than certificates representing shares to be canceled
pursuant to Section 2.1(d) above) shall be deemed from and after the Effective
Time to represent only the right to receive the corresponding Per Share Merger
Consideration upon such surrender. In no event will the holder of any such
surrendered Certificate be entitled to receive interest on any cash to be
received in the Merger. Neither the Exchange Agent nor any party hereto shall be
liable to a holder of shares of Company Capital Stock for any amount paid to a
public official pursuant to any applicable abandoned property, escheat or
similar Law.

         (c) If any Certificate shall have been lost, stolen or destroyed, upon
the making of an affidavit of that fact by the Person claiming such Certificate
to be lost, stolen or destroyed and, if required by Parent, the posting by such
Person of a bond, in such reasonable and customary amount as Parent may direct,
as indemnity against any claim that may be made against it with respect to such
Certificate, the Exchange Agent will issue the corresponding Per Share Merger
Consideration in exchange for such lost, stolen or destroyed Certificate.

         Section 2.3 DIVIDENDS; TRANSFER TAXES; WITHHOLDING. No dividends or
other distributions that are declared on or after the Effective Time on Parent
Common Stock, or are payable to the holders of record thereof who became such on
or after the Effective Time, shall be paid to any Person entitled by reason of
the Merger to receive certificates representing shares of Parent Common Stock,
until such Person shall have surrendered its Certificate(s) as provided in
Section 2.2 above. Subject to applicable Law, there shall be paid to each Person
receiving a certificate representing such shares of Parent Common Stock, at the
time of such surrender or as promptly as practicable thereafter, the amount of
any dividends or other distributions theretofore paid with respect to the shares
of Parent Common Stock represented by such Certificate and having a record date
on or after the Effective Time but prior to such surrender and a payment date on
or subsequent to such surrender. In no event shall the Person entitled to
receive such dividends or other distributions be entitled to receive interest on
such dividends or other distributions. If any cash or certificate representing
shares of Parent Common Stock is to be paid to or issued in a name other than
that in which the 



                                       5
<PAGE>   7

Certificate surrendered in exchange therefor is registered, it shall be a
condition of such exchange that the Certificate so surrendered shall be properly
endorsed and otherwise in proper form for transfer and that the Person
requesting such exchange shall pay to the Exchange Agent any transfer or other
taxes required by reason of the issuance of such certificate representing shares
of Parent Common Stock and the distribution of such cash payment in a name other
than that of the registered holder of the Certificate so surrendered, or shall
establish to the satisfaction of the Exchange Agent that such tax has been paid
or is not applicable. Parent or the Exchange Agent shall be entitled to deduct
and withhold from the consideration otherwise payable pursuant to this Agreement
to any holder of a Certificate such amounts as Parent or the Exchange Agent are
required to deduct and withhold under the Code or any provision of state, local
or foreign tax law with respect to the making of such payment. To the extent
that amounts are so withheld by Parent or the Exchange Agent, such withheld
amounts shall be treated for all purposes of this Agreement as having been paid
to the holder of the Certificate in respect of whom such deduction and
withholding were made by Parent or the Exchange Agent.

         Section 2.4 FRACTIONAL SHARES.

                  (a) No certificates or scrip representing fractional shares of
Parent Common Stock shall be issued upon the surrender for exchange of
Certificates; no dividend or distribution with respect to shares shall be
payable on or with respect to any fractional share; and such fractional share
interests shall not entitle the owner thereof to vote or to any other rights of
a shareholder of Parent.

                  (b) In lieu of any such fractional shares, each holder of
record of Company Capital Stock who would otherwise be entitled to such
fractional shares shall be entitled to an amount in cash, without interest,
rounded to the nearest cent, equal to the product of (i) the amount of the
fractional share interest in a share of Parent Common Stock to which such holder
is entitled under Sections 2.1(a) or 2.1(b) (or would be entitled but for this
Section 2.4) and (ii) the average of the closing sale prices for the Parent
Common Stock on the Nasdaq National Market, as reported in The Wall Street
Journal, Northeast edition, for each of the ten consecutive trading days ending
on the fifth complete trading day prior to the Closing Date (not counting the
Closing Date).

                  (c) As soon as practicable after the determination of the
amount of cash, if any, to be paid to holders of Company Capital Stock in lieu
of any fractional share interests in Parent Common Stock, the Exchange Agent
shall make available such amounts, without interest, to the holders of Company
Capital Stock entitled to receive such cash.

         Section 2.5 UNDISTRIBUTED PARENT COMMON STOCK. Any portion of the
certificates representing shares of Parent Common Stock issuable upon conversion
of Company Capital Stock pursuant to Section 2.1(a) or 2.1(b) hereof, together
with any dividends or distributions payable in respect thereof pursuant to
Section 2.3 hereof, which remains 



                                       6
<PAGE>   8

undistributed to the former holders of Company Capital Stock for six months
after the Effective Time shall be delivered to Parent, upon its request, and any
such former holders who have not theretofore surrendered their Certificates to
the Exchange Agent in compliance with this Article II shall thereafter look only
to Parent for payment of their claims for such shares of Parent Common Stock and
any dividends or distributions with respect to such shares of Parent Common
Stock (in each case, without interest thereon).

         Section 2.6  OPTIONS.

         (a) As soon as practicable following the date of this Agreement, the
Company's Board of Directors (or, if appropriate, any committee administering
the Option Plans (as defined below)) shall adopt such resolutions or take such
other actions as may be required to effect the following: (i) cause all options
to purchase shares of Company Common Stock (collectively "Options") granted by
the Company under the Company's stock option plans listed in Section 2.6 of the
Company Disclosure Schedule (collectively, the "Option Plans") that remain
outstanding immediately prior to the Effective Time to be assumed automatically
by Parent and converted automatically to entitle the holder thereof to subscribe
to, purchase or acquire from Parent, on the same terms and conditions as applied
under such Option immediately prior to the Effective Time (subject to the
acceleration of vesting to the extent provided under the corresponding Option
Agreements and/or employment agreements), the number of shares of Parent Common
Stock which equals the product of the corresponding Per Share Merger
Consideration times the number of shares of Company Common Stock subject to such
Option immediately prior to the Effective Time (rounded to the nearest whole
share), at an exercise price per share of Parent Common Stock equal to the
exercise price per share of Company Common Stock then specified with respect to
such Option divided by the corresponding Per Share Merger Consideration (rounded
to the nearest whole cent); provided, however, in the event of any Option which
is an incentive stock option as defined in Section 422 of the Code, the
aggregate adjusted exercise price of such Option and the number of shares to
which such Option is exercisable shall be computed in compliance in all respects
with the requirements of Section 424(a) of the Code, including the requirements
that such adjustments not confer on the holder of any Option any additional
benefits not currently provided under the corresponding Option Plan; (ii) make
such other changes to the Option Plans as it deems appropriate to give effect to
the Merger (subject to the approval of Parent, which shall not be unreasonably
withheld); (iii) ensure that no action is taken to cash out or redeem Options
prior to the Effective Time; and (iv) ensure that, after the Effective Time, no
Options may be granted under any Option Plan. As promptly as practicable after
the Effective Time, Parent shall issue to each holder of an Option a written
instrument evidencing its assumption by Parent.

         (b) Parent and the Company shall take all corporate action necessary to
effectuate the assumption of the Options as set forth in Section 2.6(a) above,
and Parent shall take all corporate actions 



                                       7

necessary to reserve for issuance a sufficient number of shares of Parent Common
Stock for delivery thereunder. Promptly (and in no event later than 20 calendar
days) after the Effective Time, Parent shall file a Registration Statement on
Form S-8 (or any successor form) under the Securities Act with respect to all
shares of Parent Common Stock subject to Options that may be registered on a
Form S-8.

         Section 2.7 NO FURTHER RIGHTS; CLOSING OF TRANSFER BOOKS. All shares of
Parent Common Stock issued pursuant to this Article II shall be deemed to have
been issued and paid in full satisfaction of all rights pertaining to the
corresponding shares of Company Capital Stock, subject, however, to the
Surviving Corporation's obligation to pay any dividends or make any other
distributions with a record date prior to the Effective Time which may have been
declared or made by the Company on such shares of Company Capital Stock in
accordance with the terms of this Agreement or prior to the date of this
Agreement and which remain unpaid at the Effective Time. At the Effective Time,
the stock transfer books of the Company shall be closed, and no transfer of
shares of Company Capital Stock shall thereafter be made. None of Parent, Merger
Sub, the Company or the Exchange Agent shall be liable to any Person in respect
of any Merger Consideration (or dividends or distributions in respect thereof
pursuant to Section 2.3 hereof) delivered to a public official pursuant to any
applicable abandoned property, escheat or similar Law. If any Certificate has
not been surrendered prior to five years after the Effective Time (or
immediately prior to such earlier date on which Merger Consideration or any
dividends or distributions with respect to Parent Common Stock as contemplated
by Section 2.3 in respect of such Certificate would otherwise escheat to or
become the property of any Government Entity), any such shares, cash, dividends
or distributions in respect of such Certificate shall, to the extent permitted
by applicable Law, become the property of the Surviving Corporation, free and
clear of all claims or interest of any Person previously entitled thereto.

         Section 2.8 FURTHER ASSURANCES. If, at any time after the Effective
Time, Parent shall consider or be advised that any deeds, bills of sale,

authorized to execute and deliver, in the name and on behalf of the Company or
otherwise, all such deeds, bills of sale, assignments and assurances and to take
and do all such other actions and things as may be necessary or desirable to
vest, perfect or confirm any and all right, title and interest in, to or under
such rights, properties or assets in the Surviving Corporation or otherwise to

rights) or Contracts to which the Company or any of its Subsidiaries is a party
relating to the issued or unissued capital stock or other equity interests of

of any Person which would be material in value to the Company; and (iv) there
are no voting trusts, proxies or other agreements or understandings to or by
which the Company or any of its Subsidiaries is a party or is bound with respect
to the voting of any shares of capital stock or other equity interests of the
Company or any of its Subsidiaries.

         Section 3.4 COMPANY SUBSIDIARIES. Section 3.4 of the Company Disclosure

the Company is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation or organization.
Each Subsidiary of the Company has the corporate power and authority to carry on
its business as it is now being conducted. Each Subsidiary of the Company is
duly qualified as a foreign corporation authorized to do business, and is in
good standing, in each jurisdiction where the character of its properties owned
or held under lease or the nature of its activities makes such qualification
necessary, except where the failure to be so qualified or in good standing would
not, individually or in the aggregate, have a Company Material Adverse Effect.
All of the outstanding shares of capital stock or other equity interests in each
of the Company's Subsidiaries have been validly issued, are fully paid and
nonassessable, and are owned by the Company or another Subsidiary of the Company
free and clear of all Encumbrances, and none are subject to preemptive rights.

execute and deliver this Agreement and, subject to the approval of the Merger by
the Company's shareholders, to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement by the Company and the consummation
by the Company of the transactions contemplated hereby have been duly authorized
by its Board of Directors and, subject to the approval of the Merger by the
Company's shareholders, no other corporate action on the part of the Company is

                                       10
<PAGE>   12

Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by the Company, constitutes a valid and binding agreement of the
Company and is enforceable against the Company in accordance with its terms. The
preparation and filing of the Proxy Statement (as defined in Section 3.16 below)
to be filed with the SEC has been duly authorized by the Board of Directors of
the Company. The Board of Directors of the Company has approved and adopted this

Company's shareholders.

         (b) The affirmative vote of the holders of a majority of the shares of
Company Common Stock and Company Series B Preferred Stock outstanding on the
record date for the Company Shareholder Meeting, voting together as a class, and
the affirmative vote of a majority of the shares of Company Series B Preferred
Stock outstanding on the record date for the Company Shareholder Meeting, voting
separately as a class, are the only votes of the holders of any class or series
of the Company's capital stock necessary to approve the Merger. No vote of the
holders of any class or series of the Company's capital stock is necessary to
approve this Agreement or consummate any transaction contemplated hereby other

limitation the Tennessee Investor Protection Act, the Tennessee Business
Combination Act, the Tennessee Control Share Acquisition Act and the Tennessee
Authorized Corporate Protection Act, and from any applicable Organizational
Document or Contract to which the Company is a party containing any change of

its Subsidiaries holds, and is in compliance with the terms of, all permits,
licenses, exemptions, orders and approvals of all Governmental Entities
necessary for the conduct of their respective businesses as currently conducted
("Company Permits"), except for failures to hold or to comply with such Company
Permits which could not, individually or in the aggregate, reasonably be
expected to have a Company Material Adverse Effect; (ii) with respect to the
Company Permits, no action or proceeding is pending or, to the knowledge of the
Company, threatened in writing, and no fact exists or event has occurred that is
expected, individually or in the aggregate, to have a Company Material Adverse
Effect; (iii) the business of the Company and its Subsidiaries has been and is
being conducted in compliance with all applicable Laws, including without

investigation or review by any Governmental Entity with respect to the Company

Effect; and (v) neither the Company nor any of its Subsidiaries have received
any written communication in the past two years from a Governmental Entity that
alleges that the Company or any of its Subsidiaries is not in compliance in any
material respect with any applicable Law.

         Section 3.7 NON-CONTRAVENTION. The execution and delivery of this
Agreement does not, and the consummation of the transactions contemplated by
this Agreement and compliance with the provisions hereof will not, (i) result in
any violation of, or default (with or without notice or lapse of time, or both)
under, require any notice or consent under, or give rise to a right of
termination, cancellation or acceleration of any obligation or to the loss of a
material benefit under any Contract binding upon the Company or any of its
Subsidiaries, or result in the creation of any Encumbrance upon any of the
properties or assets of the Company or any of its Subsidiaries, (ii) conflict
with or result in any violation of any provision of the Organizational Documents
of the Company or any of its Subsidiaries, or (iii) conflict with or violate any
Law applicable to the Company or any of its Subsidiaries or any of their
respective properties or assets, other than, in the case of clauses (i) and
(iii), any such violation, conflict, default, right, loss or Encumbrance that if
occurring, or any such notice or consent if not given or obtained, could not
reasonably be expected, individually or in the aggregate, to have a Company
Material Adverse Effect.

         Section 3.8 GOVERNMENT APPROVALS; REQUIRED CONSENTS. No filing or
registration with, or authorization, consent or approval of, any Governmental
Entity or any other third party is required by or with respect to the Company or

Material Adverse Effect.

         Section 3.9 SEC DOCUMENTS AND OTHER REPORTS. The Company has filed

from January 1, 1997 to the date of this Agreement (the "Company SEC
Documents"), and the Company SEC Documents constitute all of the documents
required to have been filed by the Company pursuant to such Laws for such
period. As of their respective dates, or if amended, as of the date of the last
such amendment, the Company SEC Documents complied, and all documents required
to be filed by the Company with the SEC after the date hereof and prior to the

material respects, with the requirements of the Securities Act or the Exchange
Act, as the case may be, and none of the Company SEC Documents contained when

statement of a material fact or omitted, or will omit, to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, or are to be made, not
misleading. Except to the extent information contained in any Company SEC
Document has been revised or superseded by a later filed Company SEC Document,
none of the Company SEC Documents (including any and all financial statements
included therein) contains any untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading. The consolidated financial statements of the Company
included in the Company SEC Documents when filed fairly presented, and those
included in the Subsequent Company SEC Documents when filed will fairly present,
and the Company's unaudited consolidated financial statements for the eleven
(11) month period ended November 30, 1998 (the "Company Interim Balance Sheet
Date") which are included in the Company Disclosure Schedule (the "Company
Interim Financial Statements") fairly present, the consolidated financial
position of the Company and its consolidated Subsidiaries as at the respective
dates thereof and the consolidated results of their operations and their
consolidated cash flows for the respective periods then ended (subject, in the
case of unaudited statements, to normal year-end audit adjustments and to any
other adjustments described therein) and have been prepared in conformity with
GAAP (except, in the case of unaudited statements, (i) as permitted by Form 10-Q
of the SEC, and (ii) with respect to those for October and November 1998, as
specified in Section 3.9 of the Company Disclosure Schedule) applied on a
consistent basis during the periods involved (except as may be indicated therein
or in the notes thereto). Since December 31, 1997, the Company has not made any
change in the accounting practices or policies applied in the preparation of its
financial statements, except as have been required by GAAP.

operations in the ordinary and usual course consistent with past practice,
except for such business and operations as have not resulted and could not

reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect; (ii) any damage, destruction or loss (whether or not
covered by insurance) having or which reasonably could be expected to have,

Company Capital Stock or any issuance or the authorization of any issuance of
any other securities in respect of, in lieu of or in substitution for shares of

officers or key employees or the creation of or any material increase in any
bonus, insurance, pension, severance or other employee benefit plan, payment or
arrangement made to, for or with any such director, officer or key employee,
other than in the ordinary course of business consistent with past practice;
(vi) any labor dispute, other than routine matters none of which has had, or
reasonably could be expected to have, a Company Material Adverse Effect; (vii)
any entry by the Company or any of its Subsidiaries into any commitment or
transaction (including, without limitation, any borrowing or capital
expenditure) material (individually or in the aggregate) to the Company or its
Subsidiaries other than in the ordinary course of business; (viii) any material
elections with respect to Taxes by the Company or any of its Subsidiaries or
settlement or compromise by the Company or any of its Subsidiaries of any
material Tax liability or refund; (ix) any change by the Company or its
Subsidiaries in accounting methods, principles or practices except as required
by concurrent changes in GAAP; (x) any Contract to take any action described in
this Section 3.10; or (xi) any event during the period from the Company Balance
Sheet Date through the date of this Agreement that, if taken during the period
from the date of this Agreement through the Effective Time, would constitute a
breach of Section 5.1 hereof.

         Section 3.11 ACTIONS AND PROCEEDINGS. Except as set forth in the
Company SEC Documents, there are no outstanding orders, judgments, injunctions,
awards or decrees of any Governmental Entity against the Company or any of its
Subsidiaries, any of their properties, assets or business, or, to the knowledge

Except as set forth in the Company SEC Documents, there are no material

knowledge of the Company, any of the Company's or its Subsidiaries' current or
former directors or officers or any other person whom the Company or any of its
Subsidiaries has agreed to indemnify, as such; nor is there any reasonable basis
for any such action, suit or proceeding that, individually or in the aggregate,
could reasonably be expected to have a Company Material Adverse Effect.

         Section 3.12 ABSENCE OF UNDISCLOSED LIABILITIES. Except for liabilities
or obligations which are accrued or reserved against on the balance sheet (or
reflected in the notes thereto) included in the Company Interim Financial
Statements, neither the Company nor any of its Subsidiaries has any material
(individually or in the aggregate) liabilities or obligations (whether absolute,

incurred in the ordinary course of business since the Company Interim Balance
Sheet Date or liabilities under this Agreement.

contemplates any joint venture, partnership or similar arrangement extending
beyond six (6) months or involving equity or investments of more than $500,000,
or (iii) is otherwise material to the Company and its Subsidiaries taken as a
whole. There is not, under any of the aforesaid obligations, any default or
event of default by the Company or other event which (with or without notice,
lapse of time or both) would constitute a default or event of default by the
Company or any of its Subsidiaries except for defaults or other events which,
individually or in the aggregate, could not reasonably be expected to have a
Company Material Adverse Effect.

         Section 3.14 TAXES. (i) The Company and each of its Subsidiaries has
filed all federal, and all material state, local, foreign and provincial tax
returns, declarations, statements, reports, schedules, bonus and information

         (a) The Company or one of its Subsidiaries owns or has the right to use

or any of its Subsidiaries (collectively, "Material Intellectual Property"), and
has the right to use, license, sublicense or assign the same without material
liability to, or any requirement of consent from, any other person or party. All

agreement; each such license agreement is valid and enforceable and in full
force and effect; neither the Company nor any of its Subsidiaries is in material

administrative action or other challenge or claim relating to any Material
Intellectual Property; there is no outstanding judgment, order, writ, injunction

Intellectual Property; and the Material Intellectual Property owned, used or
possessed by the Company or its Subsidiaries is sufficient and adequate to
conduct the business of the Company and its Subsidiaries to the full extent as
such business is currently conducted.

         (b) The Company and each of its Subsidiaries has taken reasonable steps
to protect, maintain and safeguard its respective Material Intellectual
Property, including any Material Intellectual Property for which improper or
unauthorized disclosure would impair its value or validity materially, and has
executed and required appropriate nondisclosure agreements and made appropriate
filings and registrations in connection with the foregoing.

         (c) The Company or one of its Subsidiaries is the sole and exclusive
owner of all Owned Software (as defined in Section 3.15(f) below) that is

(the "Proxy Statement") will, in the case of the Registration Statement, at the

         Section 3.17  EMPLOYEE BENEFIT PLANS; ERISA.

         (a) Section 3.17 of the Company Disclosure Schedule sets forth the name
of each Company Plan (as defined below) and of each bonus, deferred compensation
(together with a list of participants therein), incentive compensation, profit
sharing, salary continuation (together with a list of participants therein),
employee benefit, fringe benefit, stock purchase, stock option, employment,
severance, termination, golden parachute, consulting or supplemental retirement
plan or agreement (collectively, the "Benefit Plans"), true copies of which have
heretofore been made available to Parent. The Company has also delivered to
Parent true, complete and correct copies of (1) each Benefit Plan (or, in the
case of any unwritten Benefit Plans, descriptions thereof), (2) the two most
recent annual reports on Form 5500 (including all schedules and attachments
thereto) filed with the IRS with respect to each Benefit Plan (if any such
report was required by applicable Law), (3) the most recent summary plan
description (or similar document) for each Benefit Plan for which such a summary
plan description is required by applicable Law or was otherwise provided to plan
participants or beneficiaries and (4) each trust agreement and insurance or
annuity contract or other funding or financing arrangement relating to any
Benefit Plan. Each Company Plan and Benefit Plan has been administered in all
material respects in accordance with its terms and complies in all material
respects with ERISA, the Code and all other applicable Laws. All contributions
to, and payments from, the Benefit Plans that may have been required to be made
in accordance with the terms of the Benefit Plans, any applicable collective
bargaining agreement and, when applicable, Section 302 of ERISA or Section 412
of the Code, have been timely made. All such contributions to, and payments
from, the Benefit Plans, except those payments to be made from a trust qualified
under Section 401(a) of the Code, for any period ending before the Effective
Time that are not 



                                       20
<PAGE>   22

yet, but will be, required to be made, will be properly accrued and reflected in
the balance sheet included in the Company Interim Financial Statements. No
"reportable event" (within the meaning of Section 4043 of ERISA) has occurred
with respect to any Company Plan for which the 30-day notice requirement has not
been waived (other than with respect to the transactions contemplated by this
Agreement); neither the Company nor any of its ERISA Affiliates has withdrawn
from any Company Plan under Section 4063 of ERISA or Company Multiemployer Plan
(as defined below) under Section 4203 or 4205 of ERISA or has taken, or is
currently considering taking, any action to do so; and no action has been taken,
or is currently being considered, to terminate any Company Plan subject to Title
IV of ERISA. No Company Plan, nor any trust created thereunder, has incurred any
"accumulated funding deficiency" (as defined in Section 302 of ERISA), whether
or not waived. As of the most recent valuation date for each Company Plan that
is a "defined benefit plan" (as defined in Section 3(35) of ERISA (hereinafter a
"Defined Benefit Plan")), there was not any amount of "unfunded benefit
liabilities" (as defined in Section 4001(a)(18) of ERISA) under such Defined
Benefit Plan, and the Company is not aware of any facts or circumstances that
would materially change the funded status of any such Defined Benefit Plan. The
Company has furnished to Parent the most recent actuarial report or valuation
with respect to each Defined Benefit Plan. The information supplied to the plan
actuary by the Company and any ERISA Affiliate (as defined below) for use in
preparing those reports or valuations was complete and accurate in all material
respects and the Company has no reason to believe that the conclusions expressed
in those reports or valuations are incorrect. Neither the Company nor any ERISA
Affiliate has (a) engaged in a transaction described in Section 4069 of ERISA
that could subject the Company to liability at any time after the date hereof or
(b) acted in a manner that could, or failed to act so as to, result in material
fines, penalties, taxes or related charges under (x) Section 502(c)(i)(1) of
ERISA, (y) Section 4071 of ERISA or (z) Chapter 43 of the Code. There are no
material (individually or in the aggregate) actions, suits or claims pending or,
to the knowledge of the Company, threatened in writing (other than routine
claims for benefits) with respect to any Company Plan or Benefit Plan. Neither
the Company nor any of its ERISA Affiliates has incurred or could reasonably be
expected to incur any material liability under or pursuant to Title IV of ERISA
that has not been satisfied in full. To the knowledge of the Company, no
material non-exempt prohibited transactions described in Section 406 of ERISA or
Section 4975 of the Code have occurred. All Company Plans that are intended to
be qualified under Section 401(a) of the Code have received a favorable
determination letter as to such qualification from the IRS, and no event has
occurred, either by reason of any action or failure to act, which could be
expected to cause the loss of any such qualification, and the Company is not
aware of any reason why any Company Plan and Benefit Plan is not so qualified in
operation. The Company has delivered to Parent (i) a copy of the most recent
determination letter received with respect to each Company Plan for which such a
letter has been issued, as well as a copy of any pending application for a
determination letter and (ii) a list of all Company Plan amendments as to which
a favorable 



                                       21
<PAGE>   23

determination letter has not yet been received. None of the Company, any of its
ERISA Affiliates or, to the knowledge of the Company, any trustee, administrator
or other fiduciary of any Benefit Plan or any agent of any of the foregoing has
engaged in any transaction or acted in a manner that could, or has failed to act
so as to, subject the Company, any such ERISA Affiliate or any trustee,
administrator or other fiduciary to any material liability for breach of
fiduciary duty under ERISA or any other applicable law. Neither the Company nor
any of its ERISA Affiliates knows or has been notified by any Company
Multiemployer Plan that such Company Multiemployer Plan is currently in
reorganization or insolvency under and within the meaning of Section 4241 or
4245 of ERISA or that such Company Multiemployer Plan intends to terminate or
has been terminated under Section 4041A of ERISA. As used herein: (i) "Company
Plan" means (x) a "pension plan" (as defined in Section 3(2) of ERISA, other
than a Company Multiemployer Plan) or a "welfare plan" (as defined in Section
3(l) of ERISA) established or maintained by the Company or any Person that,
together with the Company, is treated as a single employer under Section 414(b),
(c), (m) or (o) of the Code (each, an "ERISA Affiliate") or to which the Company
or any of its ERISA Affiliates has contributed in the last six years or
otherwise may have any liability; and (ii) "Company Multiemployer Plan" means a
"multiemployer plan" (as defined in Section 4001(a)(3) of ERISA) to which the
Company or any of its ERISA Affiliates is or has been obligated to contribute or
otherwise may have any liability.

         (b) The consummation of the transactions contemplated by the
Transaction Agreements will not, either alone or in combination with any other
event that is reasonably likely to occur, (A) entitle any current or former
director, officer or employee of the Company or any of its ERISA Affiliates to
severance pay, golden parachute payments, unemployment compensation or any other
payment, except as expressly provided in this Agreement, or (B) accelerate the
time of payment or vesting, or increase the amount of compensation due any such
director, officer or employee.

         (c) The list of welfare plans in Section 3.17 of the Company Disclosure
Schedule discloses whether each welfare plan is (i) unfunded, (ii) funded
through a "welfare benefit fund", as such term is defined in Section 419(e) of
the Code, or other funding mechanism or (iii) insured. Each such welfare plan
may be amended or terminated without material liability to the Company at any
time after the Effective Time. The Company and its ERISA Affiliates comply in
all material respects with the applicable requirements of Section 4980B(f) of
the Code with respect to each Benefit Plan that is a group health plan, as such
term is defined in Section 5000(b)(1) of the Code.

         Section 3.18 ENVIRONMENTAL MATTERS.

         (a) No Person (including any Governmental Entity) has asserted against
the Company or any of its Subsidiaries any written requests, claims or demands
for damages, costs, expenses or causes of action 



                                       22
<PAGE>   24

arising out of (i) the emission, disposal, discharge or other release or
threatened release of any hazardous substance, pollutant or contaminant (in each
case, as defined in or governed by any applicable Law) or any other substance
the release, disposal, treatment or storage of which is regulated under
applicable Law (all of the foregoing, collectively, "Hazardous Substances") in
connection with or related to any past or present facilities, properties or
assets owned, leased or operated by the Company or any of its Subsidiaries
currently or in the past (collectively, the "Company Facilities"), or (ii) any
actual or alleged injury to human health or the environment by reason of the
current condition or operation of the Company Facilities, or past conditions and
operations or activities on the Company Facilities.

         (b) Neither the Company nor any Subsidiary is subject to any pending,
or to the knowledge of the Company, threatened (in writing) actions for damages,
costs or expenses or to any demands, claims, losses, administrative proceedings,
enforcement actions, or investigations in any case relating to or arising from
the generation, emission, disposal, discharge, release or threatened release,
treatment, or storage of any Hazardous Substance associated with the Company
Facilities or the Company's or any of its Subsidiaries' operations.

         (c) The Company and its Subsidiaries hold, and are in material
compliance with, all permits and approvals of Government Entities required under
applicable Law to operate all Company Facilities, except when the failure to
hold such permits and approvals would not result in a Company Material Adverse
Effect.

         (d) There is no environmental condition, situation or incident on, at
or concerning any Company Facility or the Company's or any of its Subsidiaries'
operations that has resulted in or could reasonably be expected to result in a
Material Adverse Effect on the Company.

         Section 3.19 AFFILIATE TRANSACTIONS. Except as set forth in the Company
SEC Documents, there are no material Contracts or other material transactions
between the Company or any of its Subsidiaries, on the one hand, and any (i)
officer or director of the Company or of any of its Subsidiaries, (ii) record or
beneficial owner of five percent or more of any class of the voting securities
of the Company or (iii) affiliate (as such term is defined in Rule 12b-2
promulgated under the Exchange Act) of any such officer, director or beneficial
owner, on the other hand.

         Section 3.20 OPINION OF FINANCIAL ADVISOR. The Company has received the
written opinion of Morgan Stanley & Co. Incorporated ("Morgan Stanley") to the
effect that the consideration to be received in the Merger by the holders of
Company Capital Stock is fair to such holders from a financial point of view. A
true, correct and complete copy of the written opinion delivered by Morgan
Stanley, which opinion shall be included in the Proxy Statement, as well as a
true and 



                                       23
<PAGE>   25

correct copy of the Company's engagement of Morgan Stanley, have been delivered
to Parent by the Company.

         Section 3.21 BROKERS. Other than Morgan Stanley, no broker, finder or
financial advisor retained by the Company is entitled to any brokerage, finder's
or other fee or commission from the Company in connection with the transactions
contemplated by this Agreement.

         Section 3.22 POOLING. The Company does not know of any reason why the
Merger will not qualify as a pooling of interests transaction under APB Opinion
No. 16. Neither the Company nor any of its Subsidiaries nor, to its knowledge,
any of its affiliates has taken or agreed to take any action that (without
giving effect to any action taken or agreed to be taken by Parent or any of its
affiliates) would prevent Parent from accounting for the business combination to
be effected by the Merger as a pooling of interests transaction under APB 16.

         Section 3.23 ACCOUNTS RECEIVABLE. All accounts receivable of the
Company and its Subsidiaries, whether or not reflected in the Company's
consolidated financial statements, represent in all material respects sales made
in the ordinary course of business, and the reserves shown on the Company's
consolidated financial statements have been established in accordance with GAAP,
consistently applied, and are considered by management of the Company to be
adequate.

a foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of its properties owned or held under lease or
the nature of its activities makes such qualification necessary, except where
the failure to be so qualified or in good standing would not have, individually
or in the aggregate a Parent Material Adverse Effect.

         Section 4.2 ARTICLES OF INCORPORATION AND BYLAWS. True, correct and
complete copies of the Articles of Incorporation and Charter, respectively, and
Bylaws, each as amended to date, of Parent and Merger Sub have been made

authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
by Parent and Merger Sub and the consummation by Parent and Merger Sub of the
transactions contemplated hereby have been duly authorized by their respective
Boards of Directors, and no other corporate action on the part of Parent or
Merger Sub (other than the approval of the issuance of shares of Parent Common
Stock in the Merger by the holders of not less than a majority of Parent's
Common Stock voted in accordance with the Nasdaq Stock Market rules) is
necessary to authorize the execution and delivery by Parent and Merger Sub of
this Agreement and the consummation by them of the transactions contemplated
hereby. This Agreement has been duly executed and delivered by Parent and Merger
Sub, constitutes a valid and binding agreement of Parent and Merger Sub and is
enforceable against Parent and Merger Sub in accordance with its terms. The
preparation and filing of the Registration Statement to be filed with the SEC
has been duly authorized by the Board of Directors of Parent. The respective
Boards of Directors of Parent and Merger Sub have approved and adopted this

series of Parent's capital stock necessary to approve the Merger or the
transactions contemplated by this Agreement.

         Section 4.5 NON-CONTRAVENTION. The execution and delivery by Parent and
Merger Sub of this Agreement do not, and the consummation 



                                       26
<PAGE>   28

of the transactions contemplated hereby and compliance with the provisions
hereof will not, (i) result in any violation of, or default (with or without
notice or lapse of time, or both) under, require any notice or consent under, or
give rise to a right of termination, cancellation or acceleration of any
obligation or to the loss of a material benefit under any Contract binding upon
Parent or Merger Sub, or result in the creation of any Encumbrance upon any of
the properties or assets of Parent or Merger Sub, (ii) conflict with or result
in any violation of any provision of the Organizational Documents of Parent or
Merger Sub, or (iii) conflict with or violate any Law applicable to Parent or
Merger Sub or any of their respective properties or assets, other than, in the
case of clauses (i) and (iii), any such violation, conflict, default, right,
loss or Encumbrance that if occurring, or any such notice or consent that if not
given or obtained, could not reasonably be expected, individually or in the
aggregate, to have a Parent Material Adverse Effect.

         Section 4.6 GOVERNMENT APPROVALS; REQUIRED CONSENTS. No filing or
registration with, or authorization, consent or approval of, any Governmental
Entity or any other third party is required by or with respect to Parent or

State of the State of Tennessee, (v) the consents, approvals, authorizations,
permits, filings and notifications listed in Section 4.6 of the Parent
Disclosure Schedule and (vi) such other consents, orders, authorizations,
registrations, declarations and filings the failure of which to obtain or make
could not reasonably be expected, individually or in the aggregate, to have a
Parent Material Adverse Effect.

         Section 4.7 SEC DOCUMENTS AND OTHER REPORTS. Parent has filed various
reports, schedules, forms, statements and other documents (which are publicly
available) with the SEC pursuant to applicable federal securities Laws from
January 1, 1997 to the date of this Agreement (the "Parent SEC Documents"), and
the Parent SEC Documents constitute all of the documents required to have been
filed by Parent pursuant to such Laws for such period. As of their respective
dates, or if amended, as of the date of the last such amendment, the Parent SEC
Documents complied, and all documents required to be filed by Parent with the
SEC after the date hereof and prior to the Effective Time ("Subsequent Parent
SEC Documents") will comply, in all material respects with the requirements of
the Securities Act or the Exchange Act, as the case may be, and none of the
Parent SEC Documents contained when filed, and the Subsequent Parent SEC
Documents will not contain when filed, any untrue statement of a material fact

<PAGE>   29

omitted, or will omit, to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, or are to be made, not misleading. Except to the extent
information contained in any Parent SEC Document has been revised or superseded
by a later filed Parent SEC Document, none of the Parent SEC Documents
(including any and all financial statements included therein) contains any
untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading. The
consolidated financial statements of Parent included in the Parent SEC Documents
when filed fairly presented, and those included in the Subsequent Parent SEC
Documents when filed will fairly present, the consolidated financial position of
Parent and its consolidated Subsidiaries, as at the respective dates thereof and
the consolidated results of their operations and their consolidated cash flows
for the respective periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments and to any other adjustments
described therein) and have been prepared in conformity with GAAP (except, in
the case of unaudited statements, as permitted by Form 10-Q of the SEC) applied
on a consistent basis during the periods involved (except as may be indicated
therein or in the notes thereto). Since December 31, 1997, Parent has not made
any change in the accounting practices or policies applied in the preparation of
its financial statements, except as have been required by GAAP.

         Section 4.8 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as set forth
in the Parent SEC Documents, since December 31, 1997, Parent has conducted its
business and operations in the ordinary and usual course consistent with past
practice, and there has not occurred (i) any event, condition or occurrence
having or that could reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect; or (ii) any declaration, setting
aside or payment of any dividend or distribution of any kind by Parent or Merger
Sub on any class of its capital stock.

         Section 4.9 INFORMATION IN DISCLOSURE DOCUMENTS AND REGISTRATION
STATEMENT. None of the information supplied or to be supplied by Parent or
Merger Sub for inclusion in (i) the Registration Statement or (ii) the Proxy
Statement will, in the case of the Registration Statement, at the time it is
filed with the SEC, at any time it is amended or supplemented and at the time it
becomes effective under the Securities Act or, in the case of the Proxy
Statement or any amendments thereof or supplements thereto, at the time of the
initial mailing of the Proxy Statement and any amendments or supplements
thereto, and at the time of each of the Company Shareholder Meeting and the
Parent Shareholder Meeting, contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they are made, not misleading. The Registration Statement, as of its effective
date, will comply as to form in all material respects with the requirements of
the Securities 



                                       28

Act. Notwithstanding the foregoing, neither Parent nor Merger Sub makes any
representation or warranty with respect to any statement made or incorporated by
reference in the Registration Statement based upon information supplied by or in
behalf of the Company for inclusion or incorporation by reference therein.

         Section 4.10 INTERIM OPERATIONS OF THE MERGER SUBSIDIARY. Merger Sub
was formed solely for the purpose of engaging in the transactions contemplated
by this Agreement, has engaged in no other business activities and has conducted
its operations only as contemplated hereby.

         Section 4.11 COMPLIANCE WITH LAWS. The business of Parent and Merger
Sub has been and is being conducted in compliance with all applicable Laws,
except for violations or failures to so comply that could not reasonably be
expected, individually or in the aggregate, to have a Parent Material Adverse
Effect; and no investigation or review by any Governmental Entity with respect
to Parent or Merger Sub is pending or, to the knowledge of Parent, threatened in
writing, other than, in each case, those which could not reasonably be expected,
individually or in the aggregate, to have a Parent Material Adverse Effect.

         Section 4.12 ACTIONS AND PROCEEDINGS. Except as set forth in the Parent
SEC Documents, there are no outstanding orders, judgments, injunctions, awards
or decrees of any Government Entity against Parent or any of its Subsidiaries,
any of their properties, assets or business, or, to the knowledge of Parent, any
of Parent's or its Subsidiaries' current or former directors or officers (during
the period served as such) or any other person whom the Company or any of its
Subsidiaries has agreed to indemnify, as such. Except as set forth in the Parent
SEC Documents, there are no material (individually or in the aggregate) actions,
suits or legal, administrative, regulatory or arbitration proceedings pending
or, to the knowledge of Parent, threatened in writing against Parent or any of
its Subsidiaries, any of their properties, assets or business, or, to the
knowledge of Parent, any of Parent's or its Subsidiaries' current or former
directors or officers or any other person whom Parent or any of its Subsidiaries
has agreed to indemnify, as such; nor is there any reasonable basis for any such
action, suit or proceeding that, individually or in the aggregate, could
reasonably be expected to have a Parent Material Adverse Effect.

         Section 4.13 ABSENCE OF UNDISCLOSED LIABILITIES. Except for liabilities
or obligations which are accrued or reserved against on the most recent balance
sheet (or reflected in the notes thereto) included in the Parent SEC Documents,
neither Parent nor any of its Subsidiaries has any material (individually or in
the aggregate) liabilities or obligations (whether absolute, accrued, contingent
or otherwise), other than liabilities or obligations incurred in the ordinary
course of business since the date of such balance sheet or liabilities under
this Agreement.

         Section 4.14 BROKERS. Other than Goldman, Sachs & Co. ("Goldman"), the
fees and expenses of which will be paid by Parent, no broker, finder or
financial advisor retained by the Parent is entitled to any brokerage, finder's
or other fee or commission from Parent in connection with the transactions
contemplated by this Agreement. A true and correct copy of Parent's engagement
letter with Goldman has been delivered to the Company by Parent.

         Section 4.15 POOLING. Parent does not know of any reason why the Merger
will not qualify as a pooling of interests transaction under APB Opinion No. 16.
Neither Parent nor any of its Subsidiaries nor, to its knowledge, any of its
affiliates has taken or agreed to take any action that (without giving effect to
any action taken or agreed to be taken by the Company or any of its affiliates)
would prevent Parent from accounting for the business combination to be effected
by the Merger as a pooling of interests transaction under APB 16.

ordinary and usual course consistent with past practice, and the Company shall

                              ADDITIONAL AGREEMENTS

         Section 6.1 ACCESS AND INFORMATION. Each party hereto shall (and shall
cause its Subsidiaries and its and their respective officers, directors,
employees, auditors and agents to) afford to the other party and to such other
party's officers, employees, financial advisors, legal counsel, accountants,
consultants and other representatives (except to the extent not permitted under
applicable Law as advised by counsel) reasonable access during normal business
hours throughout the period prior to the Effective Time to all of its books and
records and its properties, plants and personnel and, during such period, shall
furnish promptly to the other party a copy of each report, schedule and other
document filed or received by it pursuant to the requirements of federal or
state securities Laws and all other information concerning its business,
properties and personnel as such other party may reasonably request. Unless
otherwise required by applicable Law, each party hereto agrees that it shall,
and it shall cause its Subsidiaries and its and their respective officers,
directors, employees, auditors and agents to, hold in confidence all non-public
information so acquired and to use such information solely for purposes of
effecting the transactions contemplated by this Agreement as set forth in the
Confidentiality Agreement executed by Parent and Company dated December 1998
(the "Confidentiality Agreement"). Without limiting the generality of the
foregoing, the Company shall, within two business days of request therefor,
provide to Parent the information described in Rule 14a-7(a)(2)(ii) under the
Exchange Act and any information to which a holder of Company Common Stock would
be entitled under Section 48-26-102 of the TBCA (assuming such holder met the
requirements of such section).

         Section 6.2 NO SOLICITATION.

         (a) Prior to the Effective Time, the Company agrees that it shall not,
nor shall it authorize and permit its Subsidiaries or affiliates to, nor shall
it authorize or permit any director, officer, employee or agent of, or any
investment banker, attorney or other advisor or, representative of, the Company
or any of its Subsidiaries to, directly or indirectly, (i) solicit, initiate or
encourage (including by way of furnishing or disclosing non-public information)
any inquiries or the making of any proposal with respect to any merger,
consolidation or other business combination involving the Company or any
Subsidiary of the Company or the acquisition of all or any significant part of
the assets or capital stock of the Company or any Subsidiary of the Company (an
"Acquisition Transaction") or (ii) negotiate, explore or otherwise engage in
discussions with any Person (other than Parent and its representatives) with
respect to any Acquisition Transaction, or which may reasonably be expected to
lead to a proposal for an Acquisition Transaction or enter into any Contract or
understanding with respect to any such Acquisition Transaction or which would
require it to abandon, terminate or fail to 



                                       33
<PAGE>   35

consummate the Merger or any other transaction contemplated by this Agreement;
provided, however, that prior to receipt of the approval of this Agreement and
the transactions contemplated hereby by the shareholders of the Company, the
Company may, to the extent required by the fiduciary obligations of the
Company's Board of Directors, as determined in good faith by it based on the
advice of outside counsel, in response to any such proposal for an Acquisition
Transaction that was not solicited by the Company and that did not otherwise
result from a breach or a deemed breach of this Section 6.2(a), and subject to
compliance with Section 6.2(c), (x) furnish information with respect to the
Company to the Person making such proposal pursuant to a confidentiality
agreement not less restrictive of the other party than the Confidentiality
Agreement and (y) participate in negotiations regarding such proposal. Without
limiting the foregoing, it is agreed that any violation of the restrictions set
forth in the preceding sentence by any executive officer of the Company or any
of its Subsidiaries or any affiliate, director or investment banker, attorney or
other advisor or representative of the Company or any of its Subsidiaries,
whether or not such person is purporting to act on behalf of the Company or any
of its Subsidiaries or otherwise, shall be deemed to be a breach of this Section
6.2(a) by the Company.

         (b) Neither the Company's Board of Directors nor any committee thereof
shall (i) withdraw or modify, in a manner adverse to Parent or Merger Sub, the
approval or recommendation by the Company's Board of Directors or any such
committee of this Agreement or the Merger, (ii) approve any letter of intent,
agreement in principle, acquisition agreement or similar agreement relating to
any Acquisition Transaction or (iii) approve or recommend any Acquisition
Transaction; provided, however, that the Company's Board of Directors may take
any action specified in (i), (ii) or (iii) in the event that prior to the
approval of this Agreement and the transactions contemplated hereby by the
shareholders of the Company, (x) the Company's Board of Directors determines in
good faith, after it has received a Superior Proposal as defined below and after
it has received advice from outside counsel that the failure to do so would
result in a reasonable possibility that the Company's Board of Directors would
breach its fiduciary duty under applicable law, (y) the Company has notified the
Parent in writing of the determination set forth in clause (x) above, and (z) at
least five calendar days following receipt by Parent of any notice referred to
in clause (y) such Superior Proposal remains a Superior Proposal and the
Company's Board of Directors has again made the determination in clause (x)
above; and further provided that neither the Company, its Board of Directors,
nor any committee thereof shall take any action specified in clause (i), (ii) or
(iii) above without first terminating this Agreement pursuant to Section 8.1(e).
As used herein, "Superior Proposal" means a bona fide, written and unsolicited
proposal or offer (including a new or unsolicited proposal received by the
Company after the execution of this Agreement from a Person whose initial
contact with the Company may have been solicited by the Company or its
representatives prior to the execution of this Agreement) made by any Person or
group (other than Parent or any of its Subsidiaries) with respect to an
Acquisition Transaction on terms



                                       34
<PAGE>   36

which the Board of Directors of the Company determines in good faith, and in the
exercise of reasonable judgement (based on the advice of independent financial
advisors and outside legal counsel), to be reasonably capable of being
consummated and to be superior from a financial point of view to the holders of
Company Common Stock than the transactions contemplated hereby, taking into
consideration all elements of the transactions contemplated hereby including,
without limitation, the non-taxable element of said transactions (based on the
written opinion, with only customary qualifications, of the Company's financial
advisor).

         (c) The Company agrees that, as of the date hereof, it, its
Subsidiaries and affiliates, and the respective directors, officers, employees,
agents and representatives of the foregoing, shall immediately cease and cause
to be terminated any existing activities, discussions and negotiations with any
Person (other than Parent and its representatives) conducted heretofore with
respect to any Acquisition Transaction. The Company agrees to advise Parent
promptly orally and in writing of any inquiries or proposals received by, any
such information requested from, and any requests for negotiations or
discussions sought to be initiated or continued with, the Company, its
Subsidiaries or affiliates, or any of the respective directors, officers,
employees, agents or representatives of the foregoing, in each case from a
Person (other than Parent and its representatives) with respect to an
Acquisition Transaction or that reasonably could be expected to lead to any
Acquisition Transaction, and the identity of the Person making such proposal for
an Acquisition Transaction or inquiry. The Company shall keep Parent reasonably
informed of the status including any change to the material terms of any such
proposal for an Acquisition Transaction or inquiry.

         Section 6.3 THIRD-PARTY STANDSTILL AGREEMENTS. During the period from
the date of this Agreement through the Effective Time, the Company shall not
terminate, amend, modify or waive any provision of any confidentiality or
standstill agreement to which it or any of its Subsidiaries is a party.

         Section 6.4  REGISTRATION STATEMENT AND PROXY STATEMENT.

         (a) As promptly as practicable, Parent and the Company shall in
consultation with each other prepare and file with the SEC the joint Proxy
Statement and Registration Statement in preliminary form. Each of the Company
and Parent shall use reasonable efforts to have the Proxy Statement cleared by
the SEC and the Registration Statement declared effective as soon as
practicable. The Company shall furnish Parent with all information concerning
the Company and the holders of its capital stock and shall take such other
action Parent may reasonably request in connection with the Registration
Statement and the issuance of shares of Parent Common Stock in connection with
the Merger. If, at any time prior to the Effective Time, any event or
circumstance relating to the Company, any Subsidiary of the Company, Parent or
any Subsidiary of Parent, or their respective officers or directors, should be
discovered by such party which should be set 



                                       35
<PAGE>   37

forth in an amendment or a supplement to the Registration Statement or Proxy
Statement, such party promptly shall inform the other thereof and take
appropriate action in respect thereof.

         (b) The Company shall use reasonable efforts to cause to be delivered
to Parent a letter from Ernst & Young LLP, the Company's independent public
accountants, dated a date within two business days before the date on which the
Registration Statement shall become effective (and thereafter brought down to a
date within two business days of the Closing Date) and addressed to Parent, in
form and substance reasonably satisfactory to Parent and customary in scope and
substance for letters delivered by independent public accountants in connection
with registration statements similar to the Registration Statement.

         (c) Parent shall use reasonable efforts to cause to be delivered to the
Company a letter from Arthur Andersen LLP, Parent's independent public
accountants, dated a date within two business days before the date on which the
Registration Statement shall become effective (and thereafter brought down to a
date within two business days of the Closing Date) and addressed to the Company,
in form and substance reasonably satisfactory to the Company and customary in
scope and substance for letters delivered by independent public accountants in
connection with registration statements similar to the Registration Statement.

         Section 6.5 SHAREHOLDER APPROVAL.

         (a) Subject to Section 6.2, the Company, acting through its Board of
Directors, shall (i) promptly and duly call, give notice of, convene and hold as
soon as practicable following the date upon which the Registration Statement
becomes effective a meeting of the holders of Company Common Stock for the
purpose of voting to approve this Agreement and the transactions contemplated
hereby (the "Company Shareholder Meeting"), and, (ii) recommend approval and
adoption of this Agreement and the transactions contemplated hereby to the
shareholders of the Company and include in the Proxy Statement such
recommendation and (iii) take all reasonable action to solicit and obtain such
approval.

         (b) Parent, acting through its Board of Directors, shall promptly and
duly call, give notice of, convene and hold as soon as practicable following the
date upon which the Registration Statement becomes effective a meeting of the
holders of Parent Common Stock for the purpose of voting to approve the issuance
of shares of Parent Common Stock in the Merger, as required by the applicable
rules of the Nasdaq Stock Market (the "Parent Shareholder Meeting"), and
recommend approval for that purpose, include such recommendation in the Proxy
Statement, and take all reasonable action to solicit and obtain such approval.



                                       36
<PAGE>   38

         (c) Each of Parent and the Company shall cause the definitive Proxy
Statement to be mailed to its respective shareholders as soon as practicable
following the date on which the Proxy Statement is cleared by the SEC and the
Registration Statement is declared effective; provided, however, that all
mailings to either party's shareholders in connection with the Merger, including
without limitation the Proxy Statement, shall be subject to the prior review,
comment and written approval of the other party, which such other party shall
not withheld or delay unreasonably.

         Section 6.6 AFFILIATES. Prior to the mailing date of the Proxy
Statement, the Company shall cause to be prepared and delivered to Parent a list
(reasonably satisfactory to counsel for Parent) identifying each Person who, at
the time of the Company Shareholder Meeting, may be deemed to be an "affiliate"
of the Company, as such term is used in paragraphs (c) and (d) of Rule 145 under
the Securities Act (the "Company Rule 145 Affiliates"). The Company shall use
reasonable efforts to cause each Person who is identified as a Company Rule 145
Affiliate in such list to deliver to Parent as soon as possible, and not later
than the mailing date for the Proxy Statement, a written agreement,
substantially in the form of Exhibit C hereto.

         Section 6.7 COMBINED COMPANY FINANCIAL STATEMENTS. Parent shall use
reasonable efforts to file a Form 8-K with the SEC within thirty (30) days after
the end of the first full calendar month after the Effective Time to publish
financial results covering at least thirty (30) days of combined operations of
Parent and the Surviving Corporation.

         Section 6.8 REASONABLE EFFORTS.

         (a) Upon the terms and subject to the conditions herein provided and
applicable legal requirements, each of the parties hereto agrees to use
reasonable efforts to take, or cause to be taken, all action, and to do, or
cause to be done, and to assist and cooperate with the other parties hereto in
doing, as promptly as practicable, all things necessary, proper or advisable
under applicable Laws to ensure that the conditions set forth in Article VII are
satisfied and to consummate and make effective the transactions contemplated by
this Agreement; provided, however, that the Company shall not, without Parent's
prior written consent, and Parent shall not be required to, divest or hold
separate or otherwise take or commit to take any other similar action with
respect to any assets, businesses or product lines of Parent, the Company or any
of their respective Subsidiaries.

         (b) Subject to the proviso to Section 6.8(a) hereof, each of the
parties shall use reasonable efforts to obtain as promptly as practicable all
consents, waivers, approvals, authorizations or permits of, or registration or
filing with or notification to (any of the foregoing being a "Consent"), of any
Governmental Entity or any other Person required in connection with, and waivers
of any violations, defaults or breaches that may be caused by, the 



                                       37
<PAGE>   39

consummation of the transactions contemplated by the Transaction Agreements. In
connection with and without limiting the foregoing, the Company and the
Company's Board of Directors shall (i) take all action necessary to ensure that
no state takeover statute or similar Law is or becomes applicable to any
Transaction Agreement or any transaction contemplated thereby and (ii) if state
takeover statute or similar Law becomes applicable to any Transaction Agreement
or any transaction contemplated thereby, take all action necessary to ensure
that the Merger and such other transaction may be consummated as promptly as
practicable on the terms contemplated by the Transaction Agreements.

         (c) Each party hereto shall inform the other promptly of any material
communication from the SEC, the United States Federal Trade Commission, the
United States Department of Justice or any other Governmental Entity regarding
any of the transactions contemplated by the Transaction Agreements. If any party
hereto or any affiliate thereof receives a request for additional information or
documentary material from any such Governmental Entity with respect to the
transactions contemplated by the Transaction Agreements, then such party shall
use reasonable efforts to cause to be made, as soon as reasonably practicable
and after consultation with the other party, an appropriate response in
compliance with such request.

         (d) Without limiting the generality of the foregoing and subject to the
proviso to Section 6.8(a) hereof, Parent and the Company will use their
respective reasonable efforts to obtain all authorizations or waivers required
under the HSR Act to consummate the transactions contemplated by the Transaction
Agreements, including, without limitation, making all filings with the Antitrust
Division of the Department of Justice ("DOJ") and the Federal Trade Commission
("FTC") required in connection therewith (the initial filing to occur no later
than ten business days following the execution and delivery of this Agreement)
and responding as promptly as practicable to all inquiries received from the DOJ
or FTC for additional information or documentation. Each of Parent and the
Company shall furnish to the other such necessary information and reasonable
assistance as the other may request in connection with its preparation of any
filing or submission which is necessary under the HSR Act. Parent and the
Company shall keep each other apprised of the status of any communications with,
and any inquiries or requests for additional information from, the FTC and the
DOJ.

         (e) The parties hereto intend the Merger to qualify as a reorganization
under Section 368(a) of the Code. Each of the parties hereto shall, and shall
cause its respective Subsidiaries to, and shall use reasonable efforts to cause
its respective affiliates to, use its and their respective reasonable efforts to
cause the Merger to so qualify. No party hereto nor any affiliate thereof shall
take any action prior to or after the Effective Time that would cause the Merger
not to qualify under these Sections of the Code, and the parties hereto shall
take the position for all purposes that the Merger qualifies as a reorganization
under such Sections of the Code.

         Section 6.9 PUBLIC ANNOUNCEMENTS. Parent and the Company shall consult
with each other before issuing any press releases or making any public statement
with respect to the transactions contemplated by the Transaction Agreements and
shall not issue any such press release or such public statement prior to such
consultation and without the approval of the other (which approval shall not
unreasonably be withheld), except as may be required by applicable law or
obligations pursuant to any listing agreement with any national securities
exchange.

         Section 6.10 DIRECTORS' AND OFFICERS' INDEMNIFICATION; INSURANCE.

         (a) Parent and the Company agree that all rights to indemnification and
exculpation now existing in favor of any employee, agent, director or officer of
the Company and its Subsidiaries (the "Indemnified Parties"), as provided in
their respective Charters or Bylaws and their respective Indemnification
Agreements, shall survive the Merger and shall continue in full force and effect
for a period of four (4) years after the Effective Time; provided that in the
event any claim or claims are asserted or made within such four (4) year period,
all rights to indemnification in respect of any such claim shall continue until
final disposition of such claim. Parent hereby agrees, effective as of the
Effective Time, to guarantee the Company's indemnification and exculpation
obligations existing in favor of the Indemnified Parties, as provided in the
Company's and its Subsidiaries' respective applicable Charters or Bylaws and
their respective Indemnification Agreements, for the period of time set forth
under this Section 6.10(a).

         (b) Parent agrees that from and after the Effective Time, the Surviving
Corporation shall cause the policies of director and officer liability insurance
maintained by the Company on the date hereof and listed in Section 6.10 of the
Company Disclosure Schedule to be maintained in effect for the period of time
directors and officers are entitled to indemnification under Section 6.10(a)
above; provided that the Surviving Corporation may substitute therefor policies
of at least the same coverage containing terms and conditions which are no less
advantageous to the Indemnified Parties, provided that such substitution shall
not result in any gaps or lapses in coverage with respect to matters occurring
prior to the Effective Time; and provided, further, that that the Surviving
Corporation shall not be required to pay an annual premium in excess of 150% of
the last annual premium paid by the Company prior to the date hereof (the
"Maximum Amount") (which premium is set forth in Section 6.10 of the Company
Disclosure Schedule), and if the Surviving Corporation is unable to obtain the
insurance required by this Section 6.10 for the Maximum Amount, it shall obtain
as much comparable insurance as possible for an annual premium equal to the
Maximum Amount.

         (c) In the event Parent merges or is acquired in a transaction in which
it is not the surviving corporation, or if Parent sells substantially all of its
assets, Parent will cause proper provision to 



                                       39
<PAGE>   41

be made in such transaction so that Parent's successor or acquiror will assume
the obligations set forth in Sections 6.10(a) and (b) above. The parties agree
that the Company's directors and officers are the third party beneficiaries of,
and entitled to enforce, the provisions of this Section 6.10.

         Section 6.11 EXPENSES. Except as otherwise set forth in Sections 8.2(b)

to cause the shares of Parent Common Stock to be issued pursuant to this
Agreement in the Merger to be listed for trading on the Nasdaq National Market.

notice to Parent, and Parent shall give prompt notice to the Company, of (i) the
occurrence, or non-occurrence, of any event the occurrence, or non-occurrence,
of which would be likely to cause (x) any representation or warranty contained
in this Agreement to be untrue or inaccurate or (y) any covenant, condition or
agreement contained in this Agreement not to be complied with or satisfied and
(ii) any failure of the Company or Parent, as the case may be, to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder; provided, however, that the delivery of any notice pursuant to
this Section 6.13 shall not have any effect for the purpose of determining the
satisfaction of the conditions set forth in Article VII of this Agreement or
otherwise limit or affect the remedies available hereunder to any party.

         Section 6.14 POOLING OF INTERESTS. Each of the Company and Parent will
use reasonable efforts to cause the transactions contemplated by this Agreement,
including the Merger, to be accounted for as a pooling of interests under
Opinion 16 of the Accounting Principles Board and applicable SEC rules and
regulations, and such accounting treatment to be accepted by each of the
Company's and Parent's independent public accountants, and by the SEC,
respectively, and each of the Company and Parent agrees that it will not
voluntarily take any action that would cause such accounting treatment not to be
obtained.

         Section 6.15 TRANSFER TAXES. All stock transfer, real estate transfer,
documentary, stamp, recording and other similar taxes (including interest,
penalties and additions to any such Taxes) ("Transfer Taxes") incurred in
connection with the transactions contemplated by this Agreement shall be paid by

         Section 6.16 BOARD OF DIRECTORS. As soon as practicable after the
Effective Time, Parent shall cause Fred C. Goad, Jim D. Kever and William F.
Ford to be designated as members of Parent's Board of Directors, such
designations to be effective as of the first meeting of Parent's Board of
Directors subsequent to the Effective Time. Parent also shall cause Fred C.
Goad, Jim D. Kever and William F. Ford to be nominated for positions on Parent's
Board of Directors at the first meeting of Parent's shareholders subsequent to
the Effective Time, with at least one such nomination to be for a three-year
term and at least one for a two-year term. Parent shall take any and all action
necessary to cause seats to be available on its Board of Directors to enable
Parent to satisfy its commitments under this Section 6.16.

         Section 6.17  CONTINUING EMPLOYEES.

         (a) For a period of one (1) year following the Effective Time, Parent
shall, or shall cause the Surviving Corporation to, provide benefits to
continuing employees of the Company and its Subsidiaries ("Continuing
Employees") that, in the aggregate, are no less favorable than the benefits
provided, in the aggregate, to similarly situated employees of Parent.
Notwithstanding the foregoing, nothing in this Section 6.17 shall require (i)
the continuation of any benefit plan of any variety or prevent the amendment or
termination thereof (subject to the provision, in the aggregate, of the benefits
as provided in the preceding sentence) or (ii) Parent or the Surviving
Corporation to continue or maintain the employment of any Continuing Employee.

         (b) With respect to any benefits plans of Parent or its Subsidiaries in
which the Continuing Employees participate after the Effective Time, Parent
shall, or shall cause the Surviving Corporation to, use reasonable efforts to:
(i) waive any limitations as to pre-existing conditions, exclusions and waiting
periods with respect to participation and coverage requirements applicable to
the Continuing Employees under any welfare benefit plan in which such employees
may be eligible to participate after the Effective Time (provided, however, that
no such waiver shall apply to a pre-existing condition of any Continuing
Employee who was, as of the Effective Time, excluded from participation in a
Company benefit plan by nature of such pre-existing condition), (ii) provide
each Continuing Employee with credit for any co-payments and deductibles paid
prior to the Effective Time during the year in which the Effective Time occurs
in satisfying any applicable deductible or out-of-pocket requirements under any
welfare benefit plan in which such employees may be eligible to participate
after the Effective Time, and (iii) recognize all service of the Continuing
Employees with the Company for all purposes (including without limitation
purposes of eligibility to participate, vesting credit, entitlement for
benefits, and benefit accrual) in any benefit plan in which such employees may
be eligible to participate after the Effective Time, except to the extent such
treatment would result in duplicative accrual of benefits for the same period of
service. For one (1) year from the Effective Time, Parent either shall (i) cause
the Company's health and dental insurance plan to remain in effect in


                                       41
<PAGE>   43

substantially its form as of the Effective Time (which maintenance shall be
deemed to satisfy Parent's obligation pursuant to the preceding sentence with
respect to benefits of the character covered by such plan) or (ii) hold each
Continuing Employee covered by such plan as of the Effective Time harmless
against any increase in standard monthly premium expenses for family, dependent
or employee coverage (as applicable immediately prior to the Effective Time)
incurred by such Continuing Employee on account of Parent's substitution of a
different plan providing benefits of substantially the same character.

         (c) Except (i) for cause or (ii) upon the approval of a majority of the
members of a committee of Parent's Board of Directors comprised of the three
Company representatives named in Section 6.16 above and two other members of
Parent's Board of Directors designated by its Chairman, Parent shall not
terminate the employment of any Continuing Employee listed on Section 6.17 of
the Company Disclosure Schedule prior to the corresponding date specified
adjacent to such Continuing Employee's name thereon. In the event that one of
the Company representatives is unable to serve, the two remaining Company
representatives may either (a) choose the fifth member of the committee from
Parent's Board of Directors, or (b) reduce the size of the committee to three
members, comprised of the two remaining Company representatives and one other
member of Parent's Board of Directors designated by its Chairman.

         6.18 RESIGNATIONS. The Company has caused each officer and director of
the Company or any of its Subsidiaries requested by Parent to do so to resign
from each such position on or prior, and effective not later than, the Effective
Time.

Anderson, Blount, Dorsett, Mitchell & Jernigan, L.L.P. ("Smith Anderson"),

                                  EXHIBIT 99.01



                             STOCK VOTING AGREEMENT


         STOCK VOTING AGREEMENT, dated as of December 15, 1998 (the
"Agreement"), by and between certain shareholders of Envoy Corporation, a
Tennessee corporation (the "Company"), listed on Schedule A attached hereto,
(each, a "Shareholder," and collectively, the "Shareholders") and Quintiles
Transnational Corp., a North Carolina corporation ("Parent").

         WHEREAS, concurrently herewith, Parent, QELS Corp., a Tennessee
corporation and wholly owned subsidiary of Parent ("Merger Sub"), and the
Company are entering into an Agreement and Plan of Merger of even date herewith
(as amended from time to time, the "Merger Agreement"), pursuant to which Merger
Sub will merge with and into the Company with the Company as the surviving
corporation (the "Merger"); and

         WHEREAS, each Shareholder owns as of the date hereof the number of
shares of Common Stock of the Company, no par value per share (the "Common
Stock"), and/or shares of Series B Convertible Preferred Stock of the Company,
no par value per share (the "Preferred Stock"), listed next to such
Shareholder's name on Schedule A attached hereto (all such shares of Common
Stock and Preferred Stock, together with any shares of Common Stock or Preferred
Stock acquired after the date hereof and prior to the termination hereof,
constituting such Shareholder's "Shares"); and

         WHEREAS, Parent and Merger Sub have entered into the Merger Agreement
in reliance on and in consideration of, among other things, each Shareholder's
representations, warranties, covenants and agreements hereunder.

         NOW THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, and intending to be
legally bound hereby, the parties agree as follows:

         1. Voting.

         1.1 Agreement to Vote. Each Shareholder hereby revokes any and all
previous proxies with respect to such Shareholder's Shares and irrevocably
agrees to vote and otherwise act (including pursuant to written consent), with
respect to all of such Shareholder's Shares, for the approval and the adoption
of the Merger Agreement and all agreements related to the Merger and any actions
related thereto, and against any proposal or transaction which could prevent or
delay the consummation of the transactions contemplated by this Agreement or the
Merger Agreement, at any meeting or meetings of the shareholders of the 


<PAGE>   2

Company, and any adjournment, postponement or continuation thereof, at which the
Merger Agreement and other related agreements (or any amended version or
versions thereof) or such other actions are submitted for the consideration and
vote of the shareholders of the Company. The foregoing shall remain in effect
with respect to such Shareholder's Shares until the termination of this
Agreement. Each Shareholder shall execute such additional documents as Parent
may reasonably request to effectuate the foregoing.

         1.2 Waiver of Right to Dissent. Each of General Atlantic Partners 25,
L.P. and GAP Coinvestment Partners, L.P., each of which is a Shareholder (each a
"Series B Shareholder"), hereby acknowledges that it is entitled to exercise
dissenter's rights as provided in Section 4-23-101 et seq. of the Tennessee
Business Corporation Act (the "TBCA") in connection with the consideration of,
voting for and approval of the Merger by the shareholders of the Company. Each
Series B Shareholder, as a record and beneficial holder of Shares, hereby waives
irrevocably, as to all of its Shares, its right to dissent, notice of
dissenter's rights and all other rights arising under the provisions of the TBCA
with regard to dissenter's rights in connection with the Merger. Each Series B
Shareholder acknowledges that the Company and Parent will rely on such
Shareholder's waiver of these rights arising under the TBCA, and agrees that the
Company will have no obligation to provide notice of dissenter's rights to such
Series B Shareholder or to take any other or further action concerning such
Series B Shareholder's dissenter's rights otherwise available under the TBCA in
connection with the Merger.

         2. Representations and Warranties of the Shareholders. Each Shareholder
severally represents and warrants to Parent as follows:

         2.1 Ownership of Shares. On the date hereof and as of the Effective
Time (as defined in the Merger Agreement), such Shareholder's Shares specified
on Schedule A are the only shares of Common Stock or Preferred Stock owned by
such Shareholder. Except as set forth on Schedule A, such Shareholder does not
have any rights to acquire any additional shares of Common Stock or Preferred
Stock. Such Shareholder currently has, and as of the Effective Time will have
(except with respect to Shares transferred in accordance with Section 3.2),
good, valid and marketable title to such Shareholder's Shares, free and clear of
all liens, encumbrances, restrictions, options, warrants, rights to purchase and
claims of every kind (other than the encumbrances created by this Agreement and
other than restrictions on transfer under applicable federal and state
securities laws).

         2.2 Authority; Binding Agreement. Such Shareholder has the full legal
right, power and authority to enter into and perform all of such Shareholder's
obligations under this Agreement. The execution and delivery of this Agreement
by such Shareholder will not violate any other agreement to which such
Shareholder is a party, including, without limitation, any voting agreement,
shareholders' agreement or voting trust. This Agreement has been duly executed
and delivered by such Shareholder and constitutes a legal, valid and binding
agreement of such Shareholder, enforceable in accordance with its terms, except
as the enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium and similar laws now or hereafter in effect 



                                       2
<PAGE>   3

affecting creditors' rights and remedies generally or general principles of
equity. Neither the execution and delivery of this Agreement nor the
consummation by such Shareholder of the transactions contemplated hereby will
(i) violate, or require any consent, approval or notice under any provision of
any judgment, order, decree, statute, law, rule or regulation applicable to such
Shareholder or such Shareholder's Shares or (ii) constitute a violation of,
conflict with or constitute a default under, any contract, commitment,
agreement, understanding, arrangement or other restriction of any kind to which
such Shareholder is a party or by which such Shareholder is bound.

          2.3 Reliance on Agreement. Such Shareholder understands and
acknowledges that Parent and Merger Sub each are entering into the Merger
Agreement in reliance upon such Shareholder's execution, delivery and
performance of this Agreement. Such Shareholder acknowledges that the agreement
set forth in Section 1 is granted in consideration for the execution and
delivery of the Merger Agreement by Parent and Merger Sub.

         3. Notifications. Each Shareholder shall, while this Agreement is in
effect, notify Parent promptly, but in no event later than two days, of any
shares of Common Stock or Preferred Stock acquired by such Shareholder after the
date hereof.

         4. Delivery of Affiliate Letter. Contemporaneously with the execution
of this Agreement, each Shareholder shall execute and deliver to Parent on the
date hereof an Affiliate Letter substantially in the form attached hereto as
Exhibit A.

         5. Termination. This Agreement shall terminate on the earlier of (i)
the Effective Time or (ii) immediately upon the termination of the Merger
Agreement in accordance with its terms.

         6. Action in Shareholder Capacity Only. No Shareholder makes any
agreement or understanding herein as a director or officer of the Company;
rather, each Shareholder signs solely in such Shareholder's capacity as a record
holder and beneficial owner of such Shareholder's Shares, and nothing herein
shall limit or affect any actions taken in such Shareholder's capacity as an
officer or director of the Company, including without limitation any action
taken in such Shareholder's capacity as a director or executive officer of the
Company consistent with the provisions in Section 6.2 of the Merger Agreement.

         7. Miscellaneous.

         7.1 Notices. All notices, requests, claims, demands and other
communications under this Agreement shall be in writing and shall be delivered
personally or by next-day courier or telecopied (with confirmation of receipt)
to the parties at the addresses specified below (or at such other address for a
party as shall be specified by like notice; provided that notices of a change of
address shall be effective only upon receipt thereof). Any such notice shall be

supplemented except upon the execution and delivery of a written agreement

hereto without the prior written consent of the other parties.

         7.5 Governing Law. This Agreement, and all matters relating hereto,
shall be governed by, and construed in accordance with the laws of the State of
Tennessee, without giving effect to the principles of conflicts of laws thereof.

         7.6 Injunctive Relief; Jurisdiction. Each Shareholder agrees that
irreparable damage would occur and that Parent would not have any adequate
remedy at law in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It

irrevocably consents to the submission of such party to the personal
jurisdiction of the Courts in the event that any dispute arises out of this
Agreement or any of the transactions contemplated hereby, (ii) agrees that such
party will not attempt to deny or defeat such personal jurisdiction by motion or
other request for leave from any of the Courts and (iii) agrees that such party

together shall constitute one and the same document.

         7.8 Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision shall be
interpreted to be only so broad as is enforceable.

QUINTILES TRANSNATIONAL ANNOUNCES $1.7 BILLION SHARE EXCHANGE TO ACQUIRE ENVOY
CORPORATION, A LEADER IN ELECTRONIC DATA INTERCHANGE INDUSTRY 

AGREEMENT SEEN AS KEY TO EMERGING 'INFORMATICS' MODEL OF 21ST CENTURY
HEALTHCARE: EXPANDING ELECTRONIC HEALTHCARE NETWORKS TO IMPROVE MARKET
INFORMATION & HEALTHCARE DELIVERY

RESEARCH TRIANGLE PARK, N.C. and NASHVILLE, Tenn., Dec. 16 /PRNewswire/ --
Quintiles Transnational Corp. (Nasdaq: QTRN) and ENVOY Corporation (Nasdaq:
ENVY) today announced a definitive agreement for Quintiles Transnational, the
leading provider of outsourcing services to the pharmaceutical industry, to
acquire ENVOY, a leading provider of healthcare electronic data interchange and
data mining services, in a stock exchange transaction valued at approximately
$1.7 billion.

With analysts estimating 1999 projected revenue of approximately $230 million,
ENVOY processes in excess of 1 billion electronic healthcare claims annually in
the United States, including medical and pharmaceutical claims, submitted from
physicians, pharmacies, hospitals, managed care organizations, and state and
federal agencies. The combined companies, assuming completion of this and other
pending acquisitions by Quintiles, would generate revenues approaching $2
billion in 1999, according to analysts' combined estimates.

Upon completion of the agreement, Quintiles will have added another component to
its "information services" strategy. Quintiles announced yesterday that it had
signed a definitive agreement to acquire Scott-Levin, a leading U.S.
pharmaceutical market information and research services company. With ENVOY and
Scott-Levin, Quintiles will have a powerful foundation from which to build an
electronic information network for use by all segments of the healthcare
industry in advancing healthcare quality, affordability and effectiveness.

"We are very excited about what this deal can do for Quintiles," said Dennis
Gillings, Ph.D., Chairman and Chief Executive Officer of Quintiles Transnational
Corp. "ENVOY's data mining strengths and our future opportunities to bridge
healthcare databases would give our customers and the public ever better
knowledge about the effectiveness of medical procedures. We are particularly
impressed by the current data management capability to link medical diagnostic
information that is not patient specific with aggregated pharmaceutical
prescriptions by geographic area.

"This deal, once completed, will be a springboard from which we can build a
product that gives our healthcare customers access to one of the industry's most
extensive databases of medical information. This is a significant step forward
in our efforts to build a healthcare information management system as
sophisticated and effective as the medical treatments being developed and used
around the world. We see great potential for margin and revenue growth from
ENVOY in the medium and especially the long term, and we remain comfortable that
we can meet consensus analysts' estimates for 1999, excluding transaction costs
and other expenses that will not recur."

The agreement calls for an exchange of all of ENVOY stock for Quintiles stock in
a pooling of interests transaction. ENVOY shareholders would receive 1.166
shares of Quintiles common stock for each share of ENVOY common stock held.
Completion of the agreement, which is expected to be tax free to ENVOY's
shareholders, is subject to approval by ENVOY and Quintiles' shareholders,
regulatory approval and certain other customary conditions. Completion is
expected late first quarter or early second quarter of next year. Upon
completion, Quintiles will nominate three ENVOY members for election to the
Quintiles Transnational Corp.'s Board of Directors.

Under certain circumstances the agreement may be terminated if Quintiles' share
price is trading outside of a $40 to $71.50 range for a specified period prior
to closing. ENVOY's directors and preferred shareholder, who together own
approximately 16% of ENVOY stock, have entered into a stock voting agreement
whereby they agree to vote their stock in favor of the merger. At Dec. 14, 1998,
ENVOY had outstanding 24,374,795 shares of common stock and common stock
equivalents and approximately 3.5 million outstanding options, which as a result
of the merger will become exercisable for Quintiles common stock.

ENVOY, founded in 1982 and based in Nashville, Tenn., has about 1,000 employees.
Its clients include more than 200,000 physicians, 34,000 pharmacies, 38,000
dentists and 4,400 hospitals. Some analysts estimate that the size of the
healthcare electronic data interchange market is about $1 billion a year and
that it will become a $3.1 billion market by 2002.

With its May acquisition of Synergy Healthcare Inc., a healthcare information
concern based in Cambridge, Massachusetts, ENVOY entered the data mining arena,
gaining capabilities Quintiles believes will be key to the enhancement of its
future health informatics business.

"We already have one of the largest networks of connectivity in the healthcare
claims processing industry and are one of the industry leaders in each of the
four main EDI sectors," said Fred C. Goad, Jr., Chairman and Co-Chief Executive
Officer of ENVOY. "Our experience of transaction processing fits well with
Quintiles' experience of data management in the clinical trial context. Our
service offerings could benefit each and every one of Quintiles Transnational's
service groups and operating units."

Jim Kever, ENVOY's President and Co-Chief Executive Officer, said: "This
agreement will not only allow ENVOY to further expand its services within its
traditional marketplace, but also creates new channels for the use of aggregate
data in support of Quintiles' customer-focused projects. In joining forces, our
intention is to deliver timely, high-quality pharmaceutical and other healthcare
market data to customers and to expand the electronic healthcare network linking
patients, providers and payers."

Upon completion, ENVOY would operate under its own name as a wholly-owned
subsidiary of Quintiles.

Earlier this week, Quintiles announced its intention to acquire the Hoechst
Marion Roussel Inc. drug development facility in Kansas City, an agreement which
includes the industry's largest ever service contract. In a separate
announcement, Quintiles revealed its move into the healthcare informatics sector
with an agreement to acquire PMSI and its core company, Scott-Levin, a leading
U.S. provider of pharmaceutical market information and research services.
