Item 5.      Other Events
- --------------------------------------------------------------------------------

         On November 3, 1997, a definitive Capital Contribution and Share
Exchange Agreement (the "Exchange Agreement") was entered into by and among
Coventry Corporation, a Tennessee corporation ("Coventry"), Coventry Health
Care, Inc., a newly-formed Maryland corporation and wholly-owned subsidiary of
Coventry ("Newco"), Principal Mutual Life Insurance Company, an Iowa mutual
insurance company ("Principal Mutual"), Principal Holding Company, an Iowa
corporation and wholly-owned subsidiary of Principal Mutual ("Holding"), and
Principal Health Care, Inc., an Iowa corporation and wholly-owned subsidiary of
Holding ("PHC"). The terms and conditions of the transactions contemplated by
the Exchange Agreement are more fully described in the copy of the Exchange
Agreement, which is included as Exhibit 10.1 to this report.

         Pursuant to the Exchange Agreement, the shareholders of Coventry will
effect a share exchange (the "Share Exchange") with Newco, and PHC will effect a
capital contribution (the "Capital Contribution") of certain assets to Newco in
consideration of the issuance of shares of Newco's common stock, par value $0.01
per share (the "Newco Common Stock"). The Share Exchange and the Capital
Contribution are expected to qualify as tax-free transactions under Section
351(a) of the Internal Revenue Code of 1986, as amended, and the rules and
regulations promulgated thereunder.

         Pursuant to the Share Exchange: (i) each issued share of Coventry's
Common Stock, par value $0.01 per share (the "Coventry Common Stock"), shall be
converted into the right to receive one share of Newco Common Stock; (ii) each
issued and outstanding share of Coventry's Series A Convertible Preferred Stock,
par value $0.01 per share, shall be converted into the right to receive one
share of Newco's Series A Convertible Preferred Stock; (iii) each option then
outstanding under Coventry's stock option plans listed in Schedule 1.2(d) of the
Exchange Agreement (the "Coventry Options") and each warrant listed on Schedule
1.2(d) of the Exchange Agreement (the "Coventry Warrants") to purchase shares of
Coventry Common Stock shall be assumed by Newco and shall be exercisable upon
the same terms and conditions as under the applicable Coventry Options or
Coventry Warrants except that each such Coventry Option and Coventry Warrant
shall be exercisable for shares of Newco Common Stock; and (iv) each right
issued under that certain Rights Agreement by and between Coventry and
ChaseMellon Shareholder Services, L.L.C., dated February 7, 1996 and amended as
of May 7, 1997, shall be converted into the right to receive one right issuable
under a new Rights Agreement to be executed between Newco and ChaseMellon
Shareholder Services, L.L.C. (the "Newco Rights Agreement"). The exchange ratio
under the Exchange Agreement is subject to adjustment upon any stock split,
reverse stock split, stock dividend, recapitalization or other similar
transaction involving the number of issued and outstanding shares of Coventry
Common Stock. Pursuant to the Share Exchange, Coventry's shareholders will
receive approximately 60% of the shares of Newco Common Stock issued and
outstanding immediately after the Closing.

          Pursuant to the Capital Contribution, PHC will transfer to Newco
certain of its assets, including the issued and outstanding stock, of certain of
its wholly-owned subsidiaries (including its health maintenance organization
subsidiaries in Delaware, Florida, Iowa, Illinois, Kansas, Missouri, Nebraska,
Indiana, Louisiana, North Carolina, South Carolina and Georgia), all real or
personal property owned or leased by PHC, all accounts receivable, cash,
securities, contract rights, prepaid liabilities, and all other assets except
for specified excluded assets. Newco will assume all of the liabilities of PHC
except for specified excluded liabilities. In consideration of the transfer of
such assets, PHC will receive from Newco approximately 40% of the shares of
Newco Common Stock issued and outstanding immediately after the Closing and
commensurate rights under the Newco Rights Agreement.

         In connection with the Exchange Agreement, Newco will enter into an
agreement (the "Management Services Agreement") to manage that portion of
Principal Mutual's indemnity health insurance business in the Newco markets
("Transferred Health Insurance Business"), which markets will include those
geographic areas in which Coventry, PHC and their respective subsidiaries
conduct business operations. The Management Services Agreement will terminate on
December 31, 1999 at which time its indirectly wholly-owned subsidiary, Coventry
Health and Life Insurance Company will reinsure, pursuant to a coinsurance
agreement (the "Coinsurance Agreement") and have the right to renew, pursuant to
a renewal rights agreement (the "Renewal Rights Agreement"), the insurance
policies constituting the Transferred Health Insurance Business. In
consideration of these agreements, Newco will issue to Principal Mutual at the
Closing a warrant (the "Newco Warrant") that gives Principal Mutual the right to
purchase from Newco that number of shares of Newco Common Stock equal to 66 2/3%
of the total number of shares of Newco Common Stock as shall actually be issued
by Newco upon the exercise or conversion of the Coventry Options and Coventry
Warrants issued and outstanding at the Closing under the same terms and
conditions as set forth in the Coventry Options and Coventry Warrants. A copy of
the Newco Warrant is included as Exhibit 10.2 to this report and is incorporated
herein by reference in its entirety.

         At the Closing, Newco, Principal Mutual and PHC will enter into a
shareholders' agreement (the "Shareholders' Agreement") that includes (i) a
standstill agreement, pursuant to which Principal Mutual and its Affiliates
shall be prohibited from acquiring more than 40% of the issued and outstanding
Newco Common Stock and from taking certain other actions for the five-year
period following the Closing; (ii) certain restrictions on direct or indirect
transfers of Newco Common Stock by Principal Mutual and/or its Affiliates; and
(iii) registration rights pursuant to which Principal Mutual may demand that
Newco register certain of the shares of Newco Common Stock held thereby under a
registration statement filed with the Securities Exchange Commission and may
participate as a selling party in other registered offerings of the Newco Common
Stock. A copy of the Shareholders' Agreement is included as Exhibit 10.3 to this
report.

         Alan F. Wise, the president and chief executive officer of Coventry, 
will serve as Chairman and Chief Executive Officer of Newco after the Closing.
Kenneth J. Linde, president of PHC, will serve as President and Chief Operating
Officer of Newco after the Closing. Dale

B. Wolf, senior vice president, chief financial officer and treasurer of
Coventry, will serve as Chief Financial Officer and Treasurer of Newco after the
Closing.

         The Closing of the Exchange Agreement is subject to a number of
conditions, including, without limitation, the approval of the transaction by
the various state regulatory agencies that regulate Coventry, PHC and their
respective subsidiaries, the expiration of applicable waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act, as amended, the approval of the
Exchange Agreement by a majority of all Coventry's outstanding voting shares and
the establishment of a new credit facility to replace the current credit
facility between Coventry and its senior lenders.

                CAPITAL CONTRIBUTION AND SHARE EXCHANGE AGREEMENT

         This CAPITAL CONTRIBUTION AND SHARE EXCHANGE AGREEMENT (this 
"Agreement"), is executed as of the [3rd day of November], 1997, by and among
COVENTRY CORPORATION, a Tennessee corporation ("Coventry"), COVENTRY HEALTH
CARE, INC., a newly-formed Maryland corporation and wholly owned subsidiary of
Coventry ("Newco"), PRINCIPAL MUTUAL LIFE INSURANCE COMPANY, an Iowa mutual
insurance company ("Mutual"), PRINCIPAL HOLDING COMPANY, an Iowa corporation and
wholly owned subsidiary of Mutual ("Holding"), and PRINCIPAL HEALTH CARE, INC.,
an Iowa corporation and wholly owned subsidiary of Holding ("Principal").

                                    RECITALS

         WHEREAS, the Boards of Directors of Coventry and Mutual each have
determined that a strategic combination between Coventry and Principal is in the
best interests of their respective companies, shareholders and/or policyholders
(as appropriate) and presents an opportunity for their respective companies to
achieve long-term strategic and financial benefits, and accordingly have agreed
to combine their managed care businesses and to enter into this Agreement; and

         WHEREAS, for United States federal income tax purposes, it is intended
that the transfer of the Principal Assets (as defined below) by Principal to
Newco and the share exchange by Coventry's shareholders with Newco contemplated
by this Agreement qualify as a transfer subject to Section 351(a) of the
Internal Revenue Code of 1986, as amended, and the rules and regulations
promulgated thereunder (the "Code");

         NOW, THEREFORE, in consideration of the foregoing, and of the
representations, warranties, covenants and agreements contained herein, the
parties hereto agree as follows:

                                 1.
                   THE SHARE EXCHANGE AND CAPITAL CONTRIBUTION

         1.1       THE SHARE EXCHANGE. Subject to the terms and conditions of 
this Agreement, at the Effective Time (as defined in Section 2.2 hereof),
Coventry shall effect a share exchange (the "Exchange") pursuant to which each
issued share of capital stock of Coventry shall be converted into the right to
receive one share of capital stock of Newco (the ratio of one share of Newco
capital stock divided by one share of Coventry capital stock, as adjusted in
accordance with the provisions of Section 1.4 hereof, shall hereinafter be
referred to as, the "Exchange Ratio"). At and after the Effective Time, Newco
shall own all of the issued shares of capital stock of Coventry and the
shareholders of Coventry shall own that number of whole shares of capital stock
of Newco equal to the number of shares of capital stock of Coventry formerly
owned thereby. The Exchange shall have the effects specified in Section 3-114 of
the Maryland General Corporation Law (the



<PAGE>   8


"MGCL") and Section 48-21-103 of the Tennessee Business Corporation Act (the
"TBCA"). For the purposes of the Exchange, the issued shares of capital stock of
Coventry shall include shares held by Coventry Health and Life Insurance Company
("Coventry Health").

         1.2       CONVERSION OF COVENTRY SHARES AND COVENTRY RIGHTS.

         (a) At the Effective Time, (i) each share of Newco's Common Stock, par
value $0.01 per share (the "Newco Common Stock"), issued and outstanding and
held by Coventry (exclusive of shares held by Coventry Health) immediately prior
to the Effective Time shall, by virtue of the Exchange and without any action on
the part of Newco or Coventry, be canceled and retired and cease to exist; (ii)
each share of Coventry's Common Stock, par value $0.01 per share ("Coventry
Common Stock"), issued immediately prior to the Effective Time shall, by virtue
of the Exchange and without any action on the part of the holder thereof, be
converted into the right to receive that number of whole shares of Newco Common
Stock equal to the Exchange Ratio; (iii) each right (collectively, the "Coventry
Rights") issued under that certain Rights Agreement, dated February 7, 1996,
between Coventry and ChaseMellon Shareholder Services, LLC, as amended by that
First Amendment to Rights Agreement, dated May 7, 1997 (as amended, the
"Coventry Rights Plan"), issued immediately prior to the Effective Time shall,
by virtue of the Exchange and without any action on the part of the holder
thereof, be converted into the right to that number of rights (collectively, the
"Newco Rights") issuable under that certain Rights Agreement, dated as of the
Closing Date between Newco and ChaseMellon Shareholder Services, LLC (the "Newco
Rights Agreement"), equal to the Exchange Ratio; and (iv) each share of
Coventry's Series A Convertible Preferred Stock, par value $0.01 per share
("Coventry Preferred Stock"), then issued and outstanding shall, by virtue of
the Exchange and without any action on the part of the holder thereof, be
converted into the right to receive that number of shares of Newco's Series A
Convertible Preferred Stock, par value $0.01 per share ("Newco Preferred
Stock"), equal to the Exchange Ratio.

                   (b) As a result of the Exchange and without any action on the
part of the holder thereof, (i) all issued shares of Coventry Common Stock shall
be deemed to be owned by Newco, which shall effect a reverse stock split at the
Effective Time such that the number of shares of Coventry Common Stock then held
thereby shall equal 1,000 shares; (ii) each holder of a certificate (a "Common
Certificate") representing any shares of Coventry Common Stock shall thereafter
cease to have any rights with respect to such shares, except the right to
receive the Newco Common Stock upon the surrender of such Common Certificate;
(iii) each holder of a Coventry Right will be deemed to be the holder of a Newco
Right; (iv) all shares of Coventry Preferred Stock shall be canceled and retired
and shall cease to exist; and (v) each holder of a certificate (a "Preferred
Certificate") (the Common Certificates and Preferred Certificates, hereinafter
collectively being referred to as the "Certificates") representing any shares of
Coventry Preferred Stock shall thereafter cease to have any rights with respect
to such shares, except the right to receive the Newco Preferred Stock upon the
surrender of such Preferred Certificate.

                   (c) At the Effective Time, each Convertible Subordinated
Promissory Note (the "Convertible Notes") issued under that certain Amended and
Restated Securities Purchase

                                        2

Agreement, dated May 7, 1997 (the "Warburg Agreement"), by and among Coventry,
Warburg, Pincus Ventures L.P. ("Warburg") and Franklin Capital Associates III
L.P. ("Franklin") and then outstanding shall, by virtue of the Exchange and
without any action on the part of the holder thereof, be converted into the
right to receive a Convertible Subordinated Promissory Note, in accordance with
the terms of the Warburg Consent, a copy of which is attached as Exhibit 1
hereto.

                   (d) At the Effective Time, each of the options (individually,
a "Coventry Option" and collectively, the "Coventry Options") then outstanding
under Coventry's stock option plans listed on Schedule 1.2(d) hereto
(collectively, the "Coventry Stock Option Plans") shall be converted, without
any action on the part of the holder thereof, into the right to purchase that
number of shares of Newco equal to the number of shares of Coventry Common Stock
issuable upon exercise as set forth in such option. At the Effective Time, such
Coventry Options shall, by virtue of the Exchange and without any further action
on the part of Coventry or the holder of any such Coventry Option, be assumed by
Newco. At the Effective Time, all warrants listed on Schedule 1.2(d) hereto
(individually, a "Coventry Warrant" and collectively, the "Coventry Warrants")
will be assumed by Newco as provided in this Section 1.2(d). Each Coventry
Option or Coventry Warrant assumed by Newco shall be exercisable upon the same
terms and conditions as under the applicable Coventry Stock Option Plan and the
applicable Coventry Option issued thereunder or under the Coventry Warrant
except that (i) each such Coventry Option shall be exercisable for that whole
number of shares of Newco Common Stock into which the number of shares of
Coventry Common Stock subject to such Coventry Option or Coventry Warrant
immediately prior to the Effective Time would be converted under this Section
1.2(d), and (ii) the option or warrant price per share of Newco Common Stock
shall be an amount equal to the option or warrant price per share of Coventry
Common Stock subject to such Coventry Option or Coventry Warrant in effect
immediately prior to the Effective Time. Newco shall reserve for issuance the
number of shares of Newco Common Stock that will become issuable upon the
exercise of such Coventry Options and Coventry Warrants; shall file as soon as
possible after the Effective Time, and maintain the effectiveness during the
period the Coventry Options are outstanding, Registration Statements on Forms
S-8 under the Securities Act of 1933, as amended (the "Securities Act"), with
respect to the shares of Newco Common Stock issuable upon exercise of the
Coventry Options and, upon demand by Warburg pursuant to the terms of the
Warburg Agreement, will register the shares of Newco Common Stock issuable upon
exercise or conversion of the securities issued under the Warburg Agreement; and
shall take appropriate action to list all such shares with NASDAQ and to provide
appropriate notice of issuance to NASDAQ.

         1.3       EXCHANGE OF CERTIFICATES REPRESENTING NEWCO COMMON STOCK.

                   (a) As of the Effective Time, Newco shall deposit, or shall
cause to be deposited, with an exchange agent selected by Coventry, which shall
be Coventry's Transfer Agent or such other party reasonably satisfactory to
Coventry (the "Exchange Agent"), for the benefit of the holders of shares of
Coventry Common Stock and Coventry Preferred Stock, for exchange in accordance
with this Article 1, certificates representing the shares of Newco Common Stock
and Newco Preferred Stock (such cash and certificates for shares of Newco Common
Stock and Newco Preferred Stock, together with any dividends or distributions
with respect thereto, being hereinafter referred to as the

                                        3


<PAGE>   10



"Exchange Fund") to be issued pursuant to Section 1.2 and paid pursuant to this
Section 1.3 in exchange for outstanding shares of Coventry Common Stock and
Coventry Preferred Stock.

                   (b) Promptly after the Effective Time, Coventry shall cause
the Exchange Agent to mail to each holder of record of a Certificate or
Certificates (i) a letter of transmittal which shall specify that delivery shall
be effected, and risk of loss and title to the Certificates shall pass, only
upon delivery of the Certificates to the Exchange Agent and shall be in such
form and have such other provisions as Newco may reasonably specify and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing shares of Newco Common Stock and/or Newco
Preferred Stock. Upon surrender of a Certificate for cancellation to the
Exchange Agent together with such letter of transmittal, duly executed and
completed in accordance with the instructions thereto, the holder of such
Certificate shall be entitled to promptly receive in exchange therefor (x) a
certificate representing that number of whole shares of Newco Common Stock or
Newco Preferred Stock, as appropriate, and (y) a check representing the amount
of unpaid dividends and distributions, if any, which such holder has the right
to receive in respect of the Certificate surrendered pursuant to the provisions
of this Section 1.3, after giving effect to any required withholding tax, and
the Certificate so surrendered shall forthwith be canceled. No interest will be
paid or accrued on the unpaid dividends and distributions, if any, payable to
holders of Certificates. In the event of a transfer of ownership of Coventry
Common Stock or Coventry Preferred Stock which is not registered in the transfer
records of Coventry, a certificate representing the proper number of shares of
Newco Common Stock or Newco Preferred Stock, as appropriate, may be issued to
such a transferee if the Certificate representing such Coventry Common Stock or
Coventry Preferred Stock is presented to the Exchange Agent, accompanied by all
documents required to evidence and effect such transfer and to evidence that any
applicable stock transfer taxes have been paid.

                   (c) At or after the Effective Time, there shall be no
transfers on the stock transfer books of Coventry of the shares of Coventry
Common Stock which were outstanding immediately prior to the Effective Time. If,
after the Effective Time, Certificates are presented to Newco, they shall be
canceled and exchanged for certificates evidencing ownership of shares of Newco
Common Stock and/or Newco Preferred Stock deliverable in respect thereof
pursuant to this Agreement in accordance with the procedures set forth in this
Section 1.3.

                   (d) Any portion of the Exchange Fund (including the proceeds
of any investments thereof and any shares of Newco Common Stock and Newco
Preferred Stock) that remains unclaimed by the former shareholders of Coventry
one year after the Effective Time shall be delivered to Newco. Any former
shareholders of Coventry who have not theretofore complied with this Section 1.3
shall thereafter look only to Newco for payment of their shares of Newco Common
Stock and/or Newco Preferred Stock, unpaid dividends and distributions on the
Newco Common Stock and/or Newco Preferred Stock deliverable in respect of each
share of Coventry Common Stock or Coventry Preferred Stock, as appropriate, such
shareholder holds as determined pursuant to this Agreement, in each case,
without any interest thereon.

                   (e) None of Coventry, Principal, Newco, the Exchange Agent or
any other person shall be liable to any former holder of shares of Coventry
Common Stock or Coventry Preferred Stock for any amount properly delivered to a
public official pursuant to applicable abandoned property, escheat or similar
laws.

                   (f) In the event 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
Newco, the posting by such person of a bond in such reasonable amount as Newco
may direct as indemnity against any claim that may be made against it with
respect to such Certificate, the Exchange Agent will issue in exchange for such
lost, stolen or destroyed Certificate the shares of Newco Common Stock and/or
Newco Preferred Stock and unpaid dividends and distributions on shares of Newco
Common Stock and/or Newco Preferred Stock deliverable in respect thereof
pursuant to this Agreement.

         1.4       ADJUSTMENT OF EXCHANGE RATIO. In the event that, subsequent 
to the date of this Agreement but prior to the Effective Time, Coventry changes
the number of shares of Coventry Common Stock issued and outstanding as a result
of a stock split, reverse stock split, stock dividend, recapitalization or other
similar transaction, the Exchange Ratio of one share of Coventry Common Stock
for one share of Newco Common Stock and one share of Coventry Preferred Stock
for one share of Newco Preferred Stock shall be appropriately adjusted.

Coventry Material Adverse Effect, Coventry and each of the Coventry Subsidiaries
are in compliance with, and are not in violation or default under, all federal,
state and local laws, ordinances, government rules and regulations applicable to

of Coventry and the Coventry Subsidiaries has received any notice of, and to the
best of their respective knowledge, there exists no threat or claim by any
Governmental Entity of, any violation or default by Coventry or any Coventry

Coventry's knowledge, are or will be required in order to cause the current
operations or properties of Coventry or any of the Coventry Subsidiaries to
comply with any applicable laws, ordinances, governmental rules or regulations
at Closing.

                   (b) Coventry and each of the Coventry Subsidiaries have all
licenses, permits, franchises or other governmental authorizations ("Coventry

their respective businesses, except where the failure to have such Coventry
Approvals would not result in a Coventry Material Adverse Effect. None of
Coventry and the Coventry Subsidiaries has finally been denied any application
for any such Coventry Approvals necessary for their property or for the
operation of their business. There is no action pending, or to the best
knowledge of Coventry or any of the Coventry Subsidiaries, threatened or
recommended by appropriate state or federal agencies having jurisdiction
thereof, to either revoke, withdraw, or suspend any such Coventry Approvals, or
which would result in a Coventry Material Adverse Effect, or to terminate the
participation of Coventry or any of the Coventry Subsidiaries in Medicare,
Medicaid, or other government program, or any decision not to renew any such

                   (c) Coventry and the Coventry Subsidiaries have complied with
all laws, rules, conditions of participation, and regulations governing all
Medicare, Medicaid, and any other

                                       10

since January 1, 1992 to Medicare, Medicaid or any other Governmental Entity
(and/or an intermediary) or third party payor are true and complete except where
the failure to be so true and complete, together with all other such failures,
would not result in a Coventry Material Adverse Effect. Since January 1, 1992,
no deficiency in any such returns, costs reports and other filings, including
deficiencies for late filings, has been asserted or to the best of Coventry's
knowledge, after reasonable investigation, threatened by any federal, state or
local agency or instrumentality or other entities relating to Medicare or
Medicaid or other government payor or third party payor claims and to the best
of Coventry's knowledge, after reasonable investigation, there is no basis for

Coventry Material Adverse Effect. None of Coventry and the Coventry Subsidiaries
has been subject to any written finding of fraudulent procedures or practices

services (collectively, "Coventry Agreements") with the applicable state
authorities to the extent required by law, including, but not limited to
contracts required to be filed with the state Departments of Insurance,
Departments of Health or the agencies responsible for each state's Medicaid
program. Coventry and each of the Coventry Subsidiaries are not providing
services under any Agreements that have not been filed and approved by the state
regulatory authorities except where the failure to so file would not result in a
Coventry Material Adverse Effect.

                   (e) Coventry and each of the Coventry Subsidiaries is and has
operated in compliance with all contractual, statutory, regulatory, and other
requirements (collectively "Coventry Government Contracts") applicable to
entities furnishing coverage to employees of federal, state and local
governments and subdivisions and to beneficiaries under programs sponsored or
administered by any such governments or subdivisions thereof, except where

restatements of costs or charges, or other liability with

                                       11


<PAGE>   18



respect to any Coventry Government Contract, except where such claim, penalty,

all reports, filings and notices required to be filed with all applicable
Departments of Insurance, Departments of Health and HMO regulatory bodies since
January 1, 1992 except where the failure to so file would not result in a
Coventry Material Adverse Effect (as such documents have since the time of their
filing been amended, the "Coventry DOI Reports"). As of their respective dates,
the Coventry DOI Reports complied in all material respects with the requirements
of the laws, rules and regulations applicable to such DOI Reports.

                  (g) None of Coventry and any of the Coventry Subsidiaries, nor
the officers, directors, employees or agents of Coventry or any of the Coventry

order, or proposed law, rule, regulation, or order, whether federal, state,
local, or professional, which would prohibit or restrict the Coventry and the

or regulation of any court or federal, state or foreign regulatory board or body

municipal or other domestic or foreign governmental department, commission,
board, bureau, agency or instrumentality except, in the case of clause (ii), for
defaults or violations which would not result in a Coventry Material Adverse
Effect.

enter into any Commitment; (vi) any right in favor of any Person to terminate or
cancel or otherwise affect any Coventry Key Agreement or Instrument; or (vii)
the existence of a triggering event under any employment, severance or
termination agreement or other compensation arrangement or any plan, or Coventry
Plan currently in effect, which (either alone or upon the occurrence of any
additional or subsequent event) could reasonably be expected to result in any
payment, acceleration, vesting or increase in benefits to any current or former
officer, employee, director, or independent contractor of Coventry or any
Coventry Subsidiary and which would constitute an "excess parachute payment" (as
such term is defined in Section 280G(b)(1) of the Code).

                  (i) Except as disclosed in Section 3.15 of the Coventry
Disclosure Schedule, no Coventry Pension Plan has been completely or partially

adequate licenses or otherwise possess all such rights as are necessary to use
all patents (and applications therefor), patent disclosures, trademarks, service
marks, trade names, copyrights (and applications therefor), inventions,
discoveries, processes, know-how, scientific, technical, engineering and
marketing data, formulae and techniques used or proposed to be used, in or
necessary for the conduct of its business as now conducted or as proposed to be
conducted (collectively, "Coventry Intellectual Property"). The Intellectual
Property is listed in Section 3.16 of the Coventry Disclosure Schedule. None of
Coventry and any of the Coventry Subsidiaries has received notice nor otherwise
has reason to know of any conflict or alleged conflict with the rights of others
pertaining to the Intellectual Property described in this Section 3.16 where the
effect of such conflict could result in a Coventry Material Adverse Effect. To
Coventry's best knowledge, Coventry's business, and the business of any Coventry
Subsidiary, as presently conducted and as proposed to be conducted, does not
infringe upon or violate any patent rights or trade secrets of others and
neither Coventry nor any Coventry Subsidiary has received notice of any such
claim infringement or violation. To Coventry's best knowledge, Coventry and the
Coventry Subsidiaries have the right to use all trade secrets, processes,
customer lists and other rights incident to their respective businesses as now
conducted or as proposed to be conducted. To Coventry's best knowledge, no
employee of Coventry or any of the Coventry Subsidiaries has violated any
employment agreement or proprietary information agreement which he had with a
previous employer or any patent policy of such employer, or is a party (in each
case, as a defendant) to or threatened by any litigation claiming that it is
infringing on any patents, trademarks, trade secrets, service names, trade
names, copyrights, licenses and the like.

         3.17     TITLE TO TANGIBLE ASSETS. Except as set forth in Section 3.17 
of the Coventry Disclosure Schedule, Coventry and the Coventry Subsidiaries have
good and, subject to regulatory approval, marketable title to the real and
personal property they own and all rights of possession and use under all leases
regarding real and personal property they lease, in each case subject to no
mortgage, pledge, lien, lease, encumbrance or charge, other than or resulting
from taxes which have not yet become due or delinquent and minor liens and
encumbrances which do not in any case materially detract from the value of the
property subject thereto, and do not materially impair the operations of
Coventry and the Coventry Subsidiaries. With respect to each parcel of real
property owned by Coventry or a Coventry Subsidiary, Coventry or the Coventry
Subsidiary owns a valid policy of title insurance with regard to that property.

use, handling or storage in accordance with applicable federal, state and local
environmental laws of quantities thereof similar to those quantities usually
kept on similar premises by others in the same business or profession as

circumstance that could be expected to give rise to any liability by Coventry
under any Applicable Environmental Law, any other statute relating to the
environment, or any common law liability relating to the environment, including
without limitation liability related to the presence of any Hazardous Substances
on, in or under any real property or improvements now or heretofore owned,
leased, used or controlled by Coventry, and also including liability related to
the use, handling, storage, generation, production, manufacture, treatment,
release, disposal or arranging for disposal of any Hazardous Substances by or on
behalf of Coventry, and liability arising by operation of contract or law.
Except as set forth in Section 3.18(b) of the Coventry Disclosure Schedule, no
permits, registrations, licenses, authorizations, approvals or filings are
required under any Applicable Environmental Law with respect to the operation of
Coventry's business, including any such items as would be required for the use,
handling, storage, generation, production, manufacture, treatment, release,
disposal or arranging for disposal of any Hazardous Substance or other

knowledge of Coventry, there exist no agreements among shareholders of Coventry
to act in concert with respect to their voting or holding of Coventry Common
Stock.

         3.21     INTEREST IN COMPETITORS. Except as set forth in Section 3.21 
of the Coventry Disclosure Schedule, none of Coventry, the Coventry
Subsidiaries, and any of their officers and, to the best of their knowledge,

         3.24     ILLEGAL OR UNAUTHORIZED PAYMENTS AND POLITICAL CONTRIBUTIONS. 
None of Coventry, the Coventry Subsidiaries, and, to the best of their knowledge
(after reasonable inquiry of their executive officers and directors), any of the
current officers and directors of Coventry or any of the Coventry Subsidiaries
has, directly or indirectly, made or authorized any payment, contribution or
gift of money, property, or services (a) as a kickback or bribe to any Person or

political action committee contributions not involving the use of funds of
Coventry or any of the Coventry Subsidiaries and except for contributions made
in accordance with applicable state law.

         3.25     TAKEOVER STATUTE; RIGHTS PLAN. Neither Principal nor Mutual 
is, as a result of its execution and delivery of this Agreement, the performance
of its obligations hereunder or the acquisition of any Securities, an
"interested shareholder" prohibited from entering into a business combination
with Coventry or any Coventry Subsidiary pursuant to Section 3-602 of the
Business Combination Act of the State of Maryland, nor will either such party
be, at the Effective Time, an "Acquiring Person" within the meaning of the
Rights Agreement. A "Triggering Event" (as defined in the Rights Agreement)
shall not be deemed to have occurred and the Rights (as defined in the Rights
Agreement) shall not separate from the Common Stock as a result of any of the

other authority enacted with regard to corporate takeovers is applicable to the
transactions contemplated hereby.

Schedule, the Ancillary Agreements and the other agreements, documents,
certificates or written statements furnished or to be furnished to Principal,
Holding or Mutual through the Closing Date by or on behalf of Coventry in
connection with the transactions contemplated hereby do not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements contained therein or herein, in light of the circumstances in
which they were made, not misleading. There is no fact which is known to
Coventry and which has not been disclosed herein or otherwise in writing by
Coventry to Principal, Holding and Mutual which would result in a Coventry
Material Adverse Effect.

the term "Coventry Material Adverse Effect" shall mean any material adverse
effect on the business, operations, properties, prospects, condition or results

                   REPRESENTATIONS AND WARRANTIES OF PRINCIPAL

         Principal represents and warrants to Coventry and Newco that except as
expressly set forth in the correspondingly numbered section on the disclosure
schedule delivered with the execution hereof to Coventry (the "Principal
Disclosure Schedule") to the extent specifically disclosed with respect to the
representation to which such exception applies:

         4.1      CORPORATE ORGANIZATION.

                  (a) Each of Principal and the Principal Subsidiaries (a
complete list of which is set forth in Section 4.1(a) of the Principal
Disclosure Schedule) is a corporation duly organized, validly existing and in
good standing under the laws of its jurisdiction of incorporation.

                  (b) Section 4.1(b) of the Principal Disclosure Schedule
contains true and complete copies of Articles of Incorporation and Bylaws of
each of Principal and the Principal Subsidiaries, as amended through the date
hereof (collectively, the "Principal Organizational Documents").

                  (c) Each of Principal and the Principal Subsidiaries has all
requisite power and authority and has all necessary approvals, licenses, permits
and authorization to own or lease its properties and to carry on its business as
now conducted. Each of Principal and the Principal Subsidiaries has all
requisite power and authority to execute and deliver this Agreement and to
perform its obligations hereunder.

                  (d) Each of Principal and the Principal Subsidiaries has filed
all necessary documents to qualify to do business as a foreign corporation in,
and is in good standing under the laws of, each jurisdiction in which the
conduct of its business or the nature of the property owned requires such
qualification, except where the failure to so qualify would result in a
Principal Material Adverse Effect. Each of Principal and the Principal
Subsidiaries is duly registered, qualified and authorized to transact business
and is in good standing in each jurisdiction in which the conduct of its
business or the nature of its properties requires such registration,
qualification or authorization, except where the failure to be so registered,
qualified or authorized would not have a Principal Material Adverse Effect.

                  (e) All of the issued and outstanding shares of capital stock
of Principal are owned by Holding. Except as set forth in Section 4.1(e) of the
Principal Disclosure Schedule, all of the issued and outstanding capital stock
of each of the Principal Subsidiaries has been duly authorized and validly
issued, is fully paid and non-assessable, and is owned of record and
beneficially, directly or indirectly, by Principal.

         4.2      TITLE TO ASSETS. Principal has good and, subject to regulatory
requirements applicable thereto, marketable title to all of the material
Principal Assets and, except as imposed pursuant to regulatory requirements
applicable thereto, such Principal Assets are not subject to any mortgage,

refusal or to any other encumbrance, restriction or charge, including taxes,
except for taxes not yet due or delinquent and minor liens and encumbrances
which do not in any case materially detract from the value of the property
subject thereto, and do not materially impair the operations of Principal and
the Principal Subsidiaries. With respect to each parcel of real property owned
by Principal or a Principal Subsidiary, Principal or the Principal Subsidiary
owns a valid policy of title insurance with regard to that property.

         4.3      CORPORATE PROCEEDINGS, ETC. The execution, delivery and 
performance of this Agreement and each of the Ancillary Agreements by Principal
and the consummation of the transactions contemplated hereby and thereby have
been duly and validly authorized by all requisite corporate action, and no other
corporate proceedings on the part of Principal are necessary to authorize the
execution, delivery and performance of this Agreement and each of the Ancillary
Agreements and each of the transactions and agreements contemplated hereby and
thereby. This Agreement has been duly executed and delivered by Principal and
constitutes the valid and binding obligation of Principal enforceable in
accordance with its terms, except as such enforcement may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other laws of
general application affecting enforcement of creditors' rights or by general
principles of equity. As of the Closing Date, each Ancillary Agreement will have
been duly executed and delivered to Coventry by Principal and subject to the due
execution and delivery of such agreements by the other parties thereto, each
Ancillary Agreement executed by Principal will constitute the valid and binding
obligation of Principal enforceable in accordance with its terms, except as such
enforcement may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium or other laws of general application affecting enforcement of
creditors' rights or by general principles of equity.

         4.4      CONSENTS AND APPROVALS. Except as set forth in Section 4.4 to 
the Principal Disclosure Schedule, the execution and delivery by Principal of
this Agreement and any Ancillary Agreement to which it is a party, the
performance by Principal of its obligations hereunder or thereunder and the
consummation by Principal of the transactions contemplated hereby and thereby do
not require Principal or any of the Principal Subsidiaries to obtain any
consent, approval, clearance or action of, or make any filing, submission or
registration with, or give any notice to, any Person or Governmental Entity.

         4.5      COMPLIANCE WITH LAW.

                  (a) Except for violations which would not result in a
Principal Material Adverse Effect, Principal and each of the Principal
Subsidiaries are in compliance in all material respects with, and are not in
violation or default in any material respect under, all federal, state and local
laws, ordinances, government rules and regulations applicable to their business
operations, properties, or assets, including without limitation laws or
regulations relating to: the environment; occupational health and safety;
insurance companies; HMOs; PPOs; point-of-service health plans; third party
administrators; the provision or arrangement for the provision of health
services; employer benefits; ERISA plans; wages; work place safety; equal
employment opportunity and race; and religious, sex and age discrimination.
Except as set forth in Section 4.5(a) of the Principal Disclosure Schedules,
none of Principal and any of the Principal Subsidiaries has received any notice
of, and to the best of

                                       29


<PAGE>   36



their respective knowledge, there exists no threat or claim by any Governmental
Entity of, any violation or default by Principal or any of the Principal
Subsidiaries with respect to any of the foregoing. No material expenditures, to
the knowledge of Principal, are or will be required in order to cause the
current operations or properties of Principal or any of the Principal
Subsidiaries to comply with any applicable laws, ordinances, governmental rules
or regulations at Closing.

                  (b) Principal and each of the Principal Subsidiaries have all
licenses, permits, franchises or other governmental authorizations ("Principal
Approvals") necessary to the ownership of their property and to the operation of
their respective businesses, except where the failure to have such Principal
Approvals would not result in a Principal Material Adverse Effect. None of
Principal and any Principal Subsidiary has finally been denied any application
for any such Principal Approvals necessary for their property or for the
operation of their business. There is no action pending, or to the best
knowledge of Principal, threatened or recommended by appropriate state or
federal agencies having jurisdiction thereof, to either revoke, withdraw, or
suspend any such Principal Approvals, or which would result in a Principal
Material Adverse Effect, or to terminate the participation of Principal or any
of the Principal Subsidiaries in Medicare, Medicaid, or other government
program, or any decision not to renew any such Principal Approvals.

                  (c) Principal and the Principal Subsidiaries have complied in
all material respects with all laws, rules, conditions of participation, and
regulations governing all Medicare, Medicaid, and any other arrangements with
any Governmental Entity (and/or an intermediary) and have filed all returns,
cost reports and other filings in any manner prescribed thereby except where the
failure to so comply, together with all other such failures, would not result in
a Principal Material Adverse Effect. All returns, cost reports and other filings
made by Principal and the Principal Subsidiaries since January 1, 1992 to
Medicare, Medicaid or any other Governmental Entity (and/or an intermediary) or
third party payor are true and complete except where the failure to be so true
and complete, together with all other such failures, would not result in a
Principal Material Adverse Effect. Since January 1, 1992, no deficiency in any
such returns, costs reports and other filings, including deficiencies for late
filings, has been asserted or to the best of Principal's knowledge, after
reasonable investigation, threatened by any federal, state or local agency or
instrumentality or other entities relating to Medicare or Medicaid or other
government payor or third party payor claims and to the best of Principal's
knowledge, after reasonable investigation, there is no basis for any successful
claims or requests for recoupment from any such agency, instrumentality, entity
or third party payor except for any claims or requests which, together with all
other such claims or requests, would not result in a Principal Material Adverse
Effect. None of Principal and any of the Principal Subsidiaries has been subject
to any written finding of fraudulent procedures or practices arising out of the
provision of health care insurance, managed care, claims administration, or
health care services or benefits relating to Medicare, Medicaid, or any other
Governmental Entity with which Principal or any of the Principal Subsidiaries
has a contract to provide insurance, managed care, claims administration, or
health care services or benefits, and none of Principal and any of the Principal
Subsidiaries is currently subject to any pending or threatened audit relating to
such fraudulent procedures or practices.

                  (d) In each state in which Principal or any of the Principal
Subsidiaries operates HMOs, PPOs, point of service plans, insurance plans or
other health care plans, Principal and each of the Principal Subsidiaries has
filed copies of its (i) standard employer and other individual and group
subscriber agreements, (ii) contracts with physicians, hospitals and other
health care entities, and (iii) contracts for management and administrative
services (collectively, "Principal Agreements") with the applicable state
authorities to the extent required by law, including, but not limited to
contracts required to be filed with the state Departments of Insurance,
Departments of Health or the agencies responsible for each state's Medicaid
program. Principal and each of the Principal Subsidiaries are not providing
services under any Principal Agreements that have not been filed and approved by
the state regulatory authorities except where the failure to so file would not
result in a Principal Material Adverse Effect.

                  (e) Principal and each of the Principal Subsidiaries is
operating and has operated in material compliance with all contractual,
statutory, regulatory, and other requirements applicable to entities furnishing
coverage to employees of federal, state and local governments and subdivisions
and to beneficiaries under programs sponsored or administered by any such
governments or subdivisions thereof (collectively "Principal Government
Contracts"). Except as set forth in Section 4.5(e) of the Principal Disclosure
Schedule, none of Principal and any of the Principal Subsidiaries is required to
pay any claim, penalty, fine, return of premium, repayment of costs charged, or
renegotiation of charges or fees as a result of any audit, adjustment, charge,
retroactive restatements of costs or charges, or other liability with respect to
any Government Contract, except where such claim, penalty, fine, return of
premium, repayment or renegotiation would not result in a Principal Material
Adverse Effect.

                  (f) Principal and each of the Principal Subsidiaries has filed
all reports, filings and notices required to be filed with all applicable
Departments of Insurance, Departments of Health and HMO regulatory bodies since
January 1, 1992 except where the failure to so file would not result in a
Principal Material Adverse Effect (as such documents have since the time of
their filing been amended, the "Principal DOI Reports"). As of their respective
dates, the Principal DOI Reports complied in all material respects with the
requirements of the laws, rules and regulations applicable to such Principal DOI
Reports.

                  (g) None of Principal and any of the Principal Subsidiaries,
nor the officers, directors, employees or agents of Principal or any of the
Principal Subsidiaries, and to Principal's knowledge none of the persons who
provide professional services under agreements with Principal or any of the
Principal Subsidiaries (as agents of such entities) has engaged in any
activities which are prohibited under Medicare or Medicaid statutes, under
ss.ss. 1320a-7, 1320a-7a, 1320a-7b, or 1395nn of Title 42 of the United States
Code, the federal CHAMPUS statute, or the regulations promulgated pursuant to
such statutes or regulations or related state or local statutes or, to
Principal's knowledge, which are prohibited by any private accrediting
organization from which Principal or any of the Principal Subsidiaries holds or
seeks accreditation, including but not limited to:

with respect to each such existing Principal Plan.

                  (d) Except as disclosed in Section 4.15 of the Principal
Disclosure Schedule, (i) Principal and the Principal Subsidiaries have no
unfunded past service liability in respect of any of the Principal Plans; (ii)
the actuarially computed value of vested benefits under any Principal Pension

received, within the last three years, a favorable determination letter from the
Internal Revenue Service.

                  (e) Mutual, Principal, and the Principal Subsidiaries have
complied in all material respects with all applicable federal, state and local
laws, rules and regulations relating to employees' employment and/or employment

requirements of Section 4980B of the Code, Proposed Treasury Regulation Section
1.162-26 and Part 6 of Subtitle B of Title I of ERISA).

                  (f) Except as disclosed in Section 4.15 of the Principal
Disclosure Schedule, the consummation of the transactions contemplated by this
Agreement will not (i) result in the payment or series of payments by Principal
or any Principal Subsidiary to any employee or other person of an "excess
parachute payment" within the meaning of Section 280G of the Code, (ii) entitle
any employee or former employee of Principal or any Principal Subsidiary to
severance pay, unemployment compensation or any other payment, and (iii)
accelerate the time of payment or vesting of any stock option, stock

nor any entity required to be aggregated with either Mutual, Principal, or any
Principal Subsidiary under Sections 414(b), (c), (m) or (o) of the Code (a
"Principal ERISA Affiliate") has ever sponsored, participated in, contributed to
or withdrawn from a multi-employer plan as defined in Section 4001(a)(3) of
Title IV of ERISA, and neither Mutual, Principal, nor any Principal Subsidiary
nor any Principal ERISA Affiliate has ever incurred any liability as a result of
any partial or complete withdrawal by any employer from such a multi-employer
plan as described under Sections 4201, 4203, or 4205 of ERISA.

                  (i) Except as disclosed in Section 4.15 of the Principal 
Disclosure Schedule, no Principal Pension Plan has been completely or partially
terminated, or has any proceeding been

                                       41


<PAGE>   48



instituted by the PBGC to terminate any such Principal Pension Plan; neither
Mutual, Principal, nor any Principal Subsidiary nor any Principal ERISA
Affiliate has incurred or presently owes any liability to the PBGC or otherwise
under Title IV of ERISA (including PBGC premiums past due or excise taxes under
Section 4971 of the Code), or in connection with an "accumulated funding
deficiency" within the meaning of Section 302 of ERISA and Section 412 of the
Code, whether or not waived.

         4.16     PATENTS, LICENSES, ETC. Principal or one of the Principal
Subsidiaries either owns, free and clear of all encumbrances, restrictions,
liens, security interests and charges, and has good and marketable title to, or
holds adequate licenses or otherwise possesses all such rights as are necessary
to use all patents (and applications therefor), patent disclosures, trademarks,
service marks, trade names, copyrights (and applications therefor), inventions,
discoveries, processes, know-how, scientific, technical, engineering and
marketing data, formulae and techniques used or proposed to be used, in or
necessary for the conduct of its business as now conducted or as proposed to be
conducted (collectively, "Principal Intellectual Property"). The Principal
Intellectual Property is listed in Section 4.16 of the Principal Disclosure
Schedule. None of Principal nor any of the Principal Subsidiaries has received
notice nor otherwise has reason to know of any conflict or alleged conflict with
the rights of others pertaining to the Intellectual Property described in this
Section 4.16 where the effect of such conflict could result in a Principal
Material Adverse Effect. To Principal's best knowledge, Principal's business and
the business of any Principal Subsidiary, as presently conducted and as proposed
to be conducted, does not infringe upon or violate any patent rights or trade
secrets of others and neither Principal nor any Principal Subsidiary has
received notice of any such claim infringement or violation. To Principal's best
knowledge, Principal and the Principal Subsidiaries have the right to use all
trade secrets, processes, customer lists and other rights incident to their
respective businesses as now conducted or as proposed to be conducted. To
Principal's best knowledge, no employee of Principal or any of the Principal
Subsidiaries has violated any employment agreement or proprietary information
agreement which he had with a previous employer or any patent policy of such
employer. To Principal's best knowledge, none of Principal and any of the
Principal Subsidiaries, or any of their respective employees, is a party (in
each case, as a defendant) to or threatened by any litigation claiming that it
is infringing on any patents, trademarks, trade secrets, service names, trade
names, copyrights, licenses and the like.

         4.17     TITLE TO TANGIBLE ASSETS. Except as set forth in Section 4.17 
of the Principal Disclosure Schedule, Principal and the Principal Subsidiaries
have good and, subject to regulatory approval, marketable title to the real and
personal property they own and all rights of possession and use under all leases
regarding real and personal property they lease, in each case subject to no
mortgage, pledge, lien, lease, encumbrance or charge, other than or resulting
from taxes which have not yet become due or delinquent and minor liens and
encumbrances which do not in any case materially detract from the value of the
property subject thereto, and do not materially impair the operations of
Principal and the Principal Subsidiaries.

property and leases the real property used with respect to the Principal

or allowed the generation, production, use, handling, manufacture, treatment,
storage, disposal, arranging for disposal or release of any Hazardous Substances
on, in or under the Principal Properties, except for the use, handling or
storage in accordance with applicable federal, state and local environmental
laws of quantities thereof similar to those quantities usually kept on similar
premises by others in the same business or profession as Principal. To the best
knowledge of Principal, there is no past or present action, activity, event,
condition or circumstance that could be expected to give rise to any liability
by Principal under any Applicable Environmental Law, any other statute relating
to the environment, or any common law liability relating to the environment,
including without limitation liability related to the presence of any Hazardous
Substances on, in or under any real property or improvements now or heretofore
owned, leased, used or controlled by Principal, and also including liability
related to the use, handling, storage, generation, production, manufacture,
treatment, release, disposal or arranging for disposal of any Hazardous
Substances by or on behalf of Principal, and liability arising by operation of
contract or law. Except as set forth in Section 4.18(b) of the Principal
Disclosure Schedule, no permits, registrations, licenses, authorizations,
approvals or filings are required under any Applicable Environmental Law with
respect to the operation of Principal's business, including any such items as
would be required for the use, handling, storage, generation, production,
manufacture, treatment, release, disposal or arranging for disposal of any
Hazardous Substance or other materials. With respect to items listed in Section
4.18(b) of the Principal Disclosure Schedule, if any, such items are current and
Principal is in compliance with all terms and conditions therein.

                  (c) Principal has delivered to Coventry correct and complete
copies of the leases and subleases (as amended to date) listed in Section
4.18(a) of the Principal Disclosure Schedule. With respect to each such lease 
and sublease:

                      (i)      the lease or sublease is legal, valid, binding,

                               valid, binding, enforceable, and in full force
                               and effect on identical terms following the
                               consummation of the transactions contemplated
                               hereby;

                      (iii)    to Principal's knowledge, no party to the lease
                               or sublease is in breach or default, and no event
                               has occurred which, with notice or lapse of time,
                               would constitute a breach or default or permit
                               termination, modification, or acceleration
                               thereunder;

                                       43


<PAGE>   50

                               any provision thereof;

                      (v)      there are no disputes, oral agreements, or
                               forbearance programs in effect as to the lease or
                               sublease;

                      (vi)     with respect to each sublease, the
                               representations and warranties set forth in
                               subsections (i) through (v) above are true and
                               correct with respect to the underlying lease;

                      (vii)    none of Principal and the Principal Subsidiaries
                               has assigned, transferred, conveyed, mortgaged,
                               deeded in trust, or encumbered any interest in
                               the leasehold or subleasehold;

                      (viii)   all facilities leased or subleased thereunder
                               have received all approvals of governmental
                               authorities (including licenses and permits)
                               required in connection with the operation thereof
                               and have been operated and maintained in
                               accordance with applicable laws, rules, and
                               regulations;

                      (ix)     all facilities leased or subleased thereunder are
                               supplied with utilities and other services
                               necessary for the operation of said facilities;
                               and

                      (x)      the owner of the facility leased or subleased has
                               good and marketable title to the parcel of real
                               property, free and clear of any security
                               interest, easement, covenant, or other
                               restriction, except for installments of special
                               easements not yet delinquent and recorded
                               easements, covenants, and other restrictions
                               which do not impair the current use, occupancy,
                               or value, or the marketability of title, of the
                               property subject thereto.

         4.19     INSURANCE. The Principal Subsidiaries and their respective

                  (e) Mutual has filed all necessary documents to qualify to
operate the Mutual Indemnity Business as a foreign corporation in, and is in
good standing under the laws of each jurisdiction in which the conduct of the
Mutual Indemnity Business or the nature of the property owned requires such

this Agreement and any Ancillary Agreement to which it is a party, the
performance by Mutual and Holding of its respective obligations hereunder or
thereunder and the consummation by Mutual and Holding of the transactions
contemplated hereby and thereby do not require Mutual or Holding to obtain any
consent, approval, clearance or action of, or make any filing, submission or
registration with, or give any notice to, any Person or Governmental Entity.

is not in violation or default in any material respect under, all federal, state
and local laws, ordinances, government rules and regulations applicable to the

violation or default with respect to any of the foregoing. No material
expenditures, to the knowledge of Mutual, are or will be required in order to
cause the Mutual Indemnity Business to comply with any applicable laws,
ordinances, governmental rules or regulations at Closing.

                  (b) Mutual has all licenses, permits, franchises or other

Approvals necessary for performance under the Mutual Indemnity Business. There
is no action pending, or to the best knowledge of Mutual, threatened or
recommended by appropriate state or federal agencies having jurisdiction

compliance with all contractual, statutory, regulatory, and other requirements

Agreements that is a Mutual Government Contract. Except as set forth in Section
5.5(c) of the Mutual Disclosure Schedule, Mutual is not subject to any claim,
penalty, fine, return of premium, repayment of costs charged, or renegotiation
of charges or fees as a result of any audit, adjustment, charge, retroactive
restatements of costs or charges, or other liability with respect to any Mutual
Government Contract, except where such claim, penalty, fine, return of premium,
repayment or renegotiation would not result in a Mutual Material Adverse Effect.

                  (d) Mutual has filed all reports, filings and notices required
to be filed with respect to the Mutual Indemnity Business with all applicable
Departments of Insurance since January 1, 1992 except where the failure to so
file would not result in a Mutual Material Adverse Effect (as such documents
have since the time of their filing been amended, the "Mutual DOI Reports"). As
of their respective dates, the Mutual DOI Reports complied in all material
respects with the requirements of the laws, rules and regulations applicable to
such Mutual DOI Reports, except where the failure to do so would result in a
Mutual Material Adverse Effect.

         5.6      LITIGATION. Except as disclosed in Section 5.6 of the Mutual
Disclosure Schedule, there is no legal action, suit, arbitration or other legal,
administrative or other governmental investigation, inquiry or proceeding
(whether federal, state, local or foreign) pending or, to the best of Mutual's
knowledge, threatened against or affecting the Mutual Indemnity Business, except
for actions, suits, arbitrations, investigation, inquiries or proceedings that
would not result in a Mutual Material Adverse Effect. Except as set forth in
Section 5.6 of the Mutual Disclosure Schedule, there are no formally initiated
grievances or litigation pending against Mutual relating to the Mutual Indemnity
Business involving claims from accounts, clients, covered persons, or enrollees
relating to coverage of health claims or any claim for punitive, exemplary or
other extra-contractual damage except for grievances, litigation or claims which
would not result in a Mutual Material Adverse Effect. Mutual is not subject to
any order, writ, judgment, injunction, decree, determination or award of any
court or of any governmental agency or instrumentality (whether federal, state,
local or foreign) which would result in a Mutual Material Adverse Effect.

         5.7      ABSENCE OF DEFAULTS, CONFLICTS, ETC. The execution and 
delivery of this Agreement and the Coinsurance Agreement will not, and the
fulfillment of the terms hereof and thereof by Mutual will not, result in a
breach of any of the terms, conditions or provisions of, or

                                       48

constitute a default under, or result in the modification of, or permit the
acceleration of rights under or termination of, any of the Mutual Indemnity
Agreements, or any law, ordinance, code, standard, judgment, rule or regulation
of any court or federal, state or foreign regulatory board or body or
administrative agency having jurisdiction over Mutual or over the Mutual
Indemnity Business. Mutual is not in default under or in violation of (and no
event has occurred and no condition exists which, upon notice or the passage of
time (or both), would constitute a default under) (i) the Mutual Indemnity
Agreements, or (ii) any order, writ, injunction or decree of any court or any
federal, state, municipal or other domestic or foreign governmental department,
commission, board, bureau, agency or instrumentality, except, in the case of
this clause (ii), for defaults or violations which would not result in a Mutual
Material Adverse Effect.

         5.8      PREMIUM INFORMATION. The earned premium of Mutual with respect
to the portion of the Mutual Indemnity Business identified on Exhibit 4(a)
during the period beginning on January 1, 1997 and ending on September 30, 1997
was approximately $432 million.

         5.9      OWNERSHIP OF COVENTRY COMMON SHARES. Other than the 29,800 
shares of Coventry Common Stock owned by Invista Capital Management, Inc., an
indirect wholly-owned subsidiary of Mutual, neither Mutual nor any affiliate
thereof owns any shares of Coventry Common Stock or any securities exercisable
for or convertible into shares of Coventry Common Stock.

         5.10     ABSENCE OF UNDISCLOSED LIABILITIES. The Mutual Indemnity 
Business is not subject to any obligation or liability (whether accrued,
absolute, contingent, liquidated or otherwise, whether due or to become due,
whether or not known to any such party) except for obligations set forth in the
Mutual Disclosure Schedule, none of which (individually or in the aggregate)
could result in a Mutual Material Adverse Effect.

         5.11     BROKERAGE. Except as set forth on Section 5.11 of the Mutual
Disclosure Schedule, there are no claims for brokerage commissions or finder's
fees or similar compensation in connection with the transactions contemplated by
this Agreement based on any arrangement made by or on behalf of Mutual or
Holding.

         5.12     MUTUAL MATERIAL ADVERSE EFFECT. As used in this Agreement, the

the Mutual Indemnity Business taken as a whole.

                                    COVENANTS

         6.1      ACQUISITION PROPOSALS. Prior to the Effective Time, Mutual,
Holding, Principal and Coventry each agree (a) that none of them nor any of
their Subsidiaries shall, and each of them shall direct and use its best efforts
to cause its respective officers, directors, employees, agents and
representatives (including, without limitation, any investment banker, attorney
or accountant retained by it or any of its Subsidiaries) not to, initiate,
solicit or encourage, directly or indirectly, any inquiries

                                       49


<PAGE>   56



or the making or implementation of any proposal or offer (including, without
limitation, any proposal or offer to its shareholders) with respect to a merger,
share exchange, acquisition, consolidation or similar transaction directly or
indirectly involving, or any purchase or acquisition, directly or indirectly, of
all or any significant portion of the assets or any equity securities of,
Principal or any of the Principal Subsidiaries or Coventry or any of the
Coventry Subsidiaries (any such proposal or offer being hereinafter referred to
as an "Acquisition Proposal") or engage in any negotiations concerning, or
provide any confidential information or data to, or have any discussions with,
any person relating to an Acquisition Proposal, or otherwise facilitate any
effort or attempt to make or implement an Acquisition Proposal; (b) that they
and each of them will immediately cease and cause to be terminated any existing
activities, discussions or negotiations with any parties conducted heretofore
with respect to any of the foregoing and each will take the necessary steps to
inform the individuals or entities referred to above of the obligations
undertaken in this Section 6.1; and (c) that they and each of them will notify
the other parties hereto immediately if any such inquiries or proposals are
received by, any such information is requested from, or any such negotiations or
discussions are sought to be initiated or continued with it. Notwithstanding the
foregoing, any reorganization of Mutual shall not violate the provisions of this
Section 6.1 if such reorganization shall not result in any transfer of the
Principal Assets or Mutual Indemnity Agreements to any Person who is not an
Affiliate of Mutual and any such transferee agrees to be bound by the provisions
of this Agreement.

         Notwithstanding anything to the contrary contained in this Section 6.1
or in any other provision of this Agreement, Coventry and its Board of Directors
(i) may participate in discussions or negotiations (including, as a part
thereof, making any counterproposal) with or furnish information to any third
party making an unsolicited written Acquisition Proposal that the Board
determines is a bona fide offer (a "Potential Acquiror") if Coventry's Board of
Director's is advised by a nationally recognized investment banking firm
designated by Coventry and reasonably acceptable to Mutual that such Potential
Acquiror has the financial wherewithal to consummate such an Acquisition
Proposal (or that it is confident that such Potential Acquiror will be capable
of consummating such Acquisition Proposal) provided that (a) the Board
determines in good faith, after receiving advice from such financial advisor,
that such third party has submitted to Coventry an Acquisition Proposal which is
a superior proposal to the transactions contemplated under this Agreement (a
"Superior Proposal"), and (b) the Board determines in good faith, based upon
advice of its outside legal counsel, that participation in such discussions or
negotiations or furnishing such information is necessary to fulfill the Board's
fiduciary duties under applicable law. The Board shall be entitled to withdraw
its recommendation in favor of the transactions contemplated by this Agreement,
and to approve and recommend acceptance by shareholders of an unsolicited
written Acquisition Proposal that is a Superior Proposal if the Board determines
in good faith that such actions are in the best interests of its shareholders,
and, based upon advice of its outside counsel the Board determines in good faith
that such approval is necessary to fulfill the Board's fiduciary duty under
applicable law, and provision is made by Potential Acquiror to pay the fee
provided in Section 8.5(b) at the time therein specified. Coventry agrees that
any non-public information furnished to a Potential Acquiror will be pursuant to
a confidentiality agreement substantially similar to the confidentiality
provisions of the confidentiality agreement entered into between Coventry,
Mutual and Principal. In the event that Coventry shall determine to provide any
information as described above, or shall receive any such

                                       50


<PAGE>   57



unsolicited Acquisition Proposal, it shall promptly inform Mutual in writing as
to the fact that information is to be provided and shall furnish to Mutual the
identity of the recipient of such information and/or the Potential Acquiror and
the terms of such Acquisition Proposal, except to the extent that the Board
determines in good faith, based upon advice of its outside legal counsel, that
any such action described in this sentence would violate such Board's fiduciary
duties under, or otherwise violate, applicable law. Coventry will keep Mutual
reasonably informed of the status (including amendments or proposed amendments)
of any such Acquisition Proposal except to the extent that the Board determines
in good faith, based upon advice of its outside legal counsel, that any such
action would violate such Board's fiduciary duties under, or otherwise violate,
applicable law.

         6.2      BEST EFFORTS. Subject to the terms and conditions of this
Agreement, each party will use its reasonable best efforts to take, or to cause
to be taken, all actions and to do, or cause to be done, all things necessary,
proper or advisable under applicable laws and regulations to consummate the
Exchange and Capital Contribution and the other transactions contemplated by
this Agreement and each of the Ancillary Agreements.

         6.3      CONDUCT OF BUSINESSES. Prior to the Effective Time, except as

unreasonably withheld, each of Newco, Coventry and Principal shall, and shall

Commission as promptly as practicable. Coventry shall use its best efforts to
obtain, prior to the effective date of the Form S-4, all necessary state
securities law or "Blue Sky" permits or approvals required to carry out the
transactions contemplated by this Agreement and will pay all expenses incident
thereto. Coventry will use its best efforts to cause the Proxy
Statement/Prospectus to be mailed to Coventry's stockholders as promptly as
practicable after the Form S-4 is declared effective under the Securities Act.
Coventry agrees that the Proxy Statement/Prospectus and each amendment or
supplement thereto at the time of mailing thereof and at the time of the
meeting(s) of shareholders of Coventry, or, in the case of the Form S-4 and each
amendment or supplement thereto, at the time it is filed or becomes effective,
will not include an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading; provided, however, that the foregoing shall not apply to the extent
that any such untrue statement of a material fact or omission to state a
material fact was made by Coventry in reliance upon and in conformity with
written information concerning Principal furnished to Coventry by Principal
specifically for use in the Proxy Statement/Prospectus. Principal agrees that
the information provided by it for inclusion in the Proxy Statement/Prospectus
and each amendment or supplement thereto, at the time of mailing thereof and at

information provided by Principal for inclusion in the Form S-4 or any amendment
or supplement thereto, at the time it is filed or becomes effective, will not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. No
amendment or supplement to the Proxy Statement/Prospectus will be made by
Coventry or Principal without the approval of the other party. Coventry will
advise Principal, promptly after it receives notice thereof, of the time when
the Form S-4 has become effective or any supplement or amendment has been filed,

Common Stock issuable in connection with the Exchange and the Capital
Contribution for offering or sale in any jurisdiction, or any request by the

comments thereon and responses thereto or requests by the Commission for
additional information.

Ernst & Young LLP, independent public accountants for Principal, dated the date
of the Proxy Statement/Prospectus, with respect to the financial statements of
Principal and any others as may be required to be included in the Proxy
Statement/Prospectus, substantially in the form described in Section 7.2(b) (the

         6.19     TANGIBLE NET VALUE.

                  (a) Prior to the Effective Time, (i) Coventry shall conduct
further review of the balance sheet of Principal and/or any of the Principal
Subsidiaries, and Principal and Coventry shall consult concerning certain
adjustments to the balance sheet, if any, and a corresponding decrease in
stockholder's equity ("Net Worth Decrease") of Principal and the Principal
Subsidiaries, on a consolidated basis, which Net Worth Decrease Coventry
believes to be appropriate after consultation with Arthur Andersen LLP, in order
for such balance sheet to be in accordance with GAAP; and (ii) Principal and
Mutual shall conduct further review of Coventry's reserves for contingent FEHBP
liabilities, and if such reserves are considered to be inadequate by Principal
and Mutual, Principal and Mutual shall conduct further review of all of
Coventry's claims reserves and determine certain adjustments, if any, to such
reserves ("Reserve Adjustment") which they believe to be appropriate after
consultation with Ernst & Young LLP. If the parties shall agree on the amount of
the Net Worth Decrease and the amount of the Reserve Adjustment, the Reserve
Adjustment shall reduce the Net Worth Decrease, but not less than zero. If the
parties shall not agree on the amount of Net Worth Decrease and the amount of
the Reserve Adjustment, such amounts shall be determined in accordance with
Section 6.19(c).

                  (b) As used herein, the term "Tangible Net Value" shall mean
the difference as of immediately prior to the Effective Time between (x) the
aggregate book value of the tangible Principal Assets calculated in accordance
with GAAP, consistent with the accounting principles applied in Principal's
financial statements as adjusted pursuant to Section 6.19(a) hereof and (y) the
aggregate book value of the Assumed Liabilities calculated in accordance with
GAAP, consistent with the accounting principles applied in Principal's financial
statements as adjusted pursuant to Section 6.19(a) hereof.

                  (c) At or promptly after the Effective Time (and in any event,
within 45 days), Arthur Andersen LLP shall prepare and deliver to each of Newco,
Mutual and Ernst & Young LLP a balance sheet (the "Closing Balance Sheet") that
sets forth the Tangible Net Value. If the parties cannot agree on the Net Worth
Decrease or the Reserve Adjustment, or the calculation of the Tangible Net Value
on the Closing Balance Sheet on or before the 30th day immediately following

                                       59


<PAGE>   66



receipt of the Closing Balance Sheet, then Arthur Andersen LLP and Ernst & Young
LLP shall seek to reach such agreement and if those two firms cannot reach
agreement as to the Net Worth Decrease, the Reserve Adjustment and/or Tangible
Net Value, as applicable, on or before the 60th day following receipt of the
Closing Balance Sheet, then they shall appoint a third nationally recognized
accounting firm to calculate such amounts. Such accounting firm selected in
accordance with the foregoing provisions shall promptly prepare and deliver to
each of Newco and Mutual a revised Closing Balance Sheet that sets forth the
amounts in controversy. Any determination of the amounts in accordance with the
provisions of this Section 6.19(c) shall be final and binding on the parties
hereto.

                  (d) If the Tangible Net Value shall be less than $103,000,000
(the "Target Value"), then Principal and/or Mutual shall deliver to Newco cash
by wire transfer of immediately available funds in an amount equal to the
difference between the Tangible Net Value and the Target Value promptly after
the 30th day immediately following receipt of the Closing Balance Sheet or, if
later, promptly after the determination of the Tangible Net Value in accordance
with the provisions of Section 6.19(c) hereof. If the Tangible Net Value shall
be greater than the Target Value, then Newco shall deliver to Principal cash by
wire transfer of immediately available funds in an amount equal to the
difference between the Tangible Net Value and the Target Value.

         6.20     TAXES.

                  (a) Except as contemplated by this Agreement, on or prior to
the Closing Date, Principal and Mutual shall terminate any tax-sharing
agreements or similar arrangements with respect to or involving the Principal
Subsidiaries after settling all obligations thereunder. The Principal
Subsidiaries shall not thereafter be bound thereby or have any liability
thereunder for amounts due in respect of Pre-Acquisition Date Tax Periods,
except as provided in Section 6.20(b).

                  (b) Coventry and Principal acknowledge that the Principal
Subsidiaries will be required to join in the filing of a consolidated federal
income tax return with Mutual for the period from January 1, 1997, to the
Effective Time. Mutual shall be responsible for paying the actual federal income
Tax due for the Principal Subsidiaries for the period in 1997 ending on the
Effective Time. In the determination of Tangible Net Value pursuant to Section
6.20(b), the Closing Balance Sheet shall not reflect any liability for the
portion of such federal income Tax of the Mutual consolidated group for 1997
attributable to Principal or the Principal Subsidiaries.

                  (c) For any state or local income, franchise or other Tax
Return of a Principal Subsidiary that involves a period beginning before and
ending after the Effective Time (a "Straddle Period"), regardless of who pays
the Tax to the governmental authority, Principal shall be responsible for the
portion of the Tax attributable to the Pre-Acquisition Date Tax Period (except
for premium taxes) and Coventry shall be responsible for the portion of the Tax
attributable to the Post- Acquisition Date Tax Period. The allocation of total
Tax paid in connection with any such Tax Return between the Pre-Acquisition Date
Tax Period and the Post-Acquisition Date Tax Period shall be in proportion to
the number of days in each such period. For premium taxes, the allocation of
total Tax paid between the Pre-Acquisition Date Tax Period and the
Post-Acquisition Date Tax Period

                                       60


<PAGE>   67



shall be based on the gross premiums (or other measure of such Tax) received
during the Pre- Acquisition Date Tax Period and the Post-Acquisition Date Tax
Period, respectively, with such premiums being pro-rated on a daily basis for
the month within which the Effective Time falls. If Coventry or the Principal
Subsidiary should pay more Tax after the Effective Time with regard to a Tax
Return for a Straddle Period than required by the foregoing allocation, then
Principal shall reimburse Coventry or the Principal Subsidiary for the excess
amount paid by Coventry or the Principal Subsidiary after the Effective Time. If
Principal or the Principal Subsidiary should pay more Tax before the Effective
Time with regard to a Return for a Straddle Period than required by the
foregoing allocation, then Coventry shall reimburse Principal for the excess
amount paid by Principal or the Principal Subsidiary before the Effective Time.

                  (d) Mutual shall have the right to pursue and shall be
entitled to retain, or receive from Newco or any of its Subsidiaries (including
the Principal Subsidiaries) prompt payment of, any overpayment, refund or credit
of Taxes for any and all Pre-Acquisition Date Tax Periods. If Newco or any of
its Subsidiaries (including the Principal Subsidiaries) receives a Tax refund to
which Mutual is entitled pursuant to this Agreement, Newco or the Subsidiary, as
the case may be, shall pay or cause the recipient to pay the amount of such
refund (including any interest received thereon) to such other party within 10
days after receipt thereof. Within 90 days after the end of each taxable year
following the Closing Date, Newco shall have its tax officer tender to Mutual a
statement showing the aggregate amount of all Tax refunds received to which
Mutual is entitled.

                  (e) Upon request, Newco shall promptly provide (and cause any
of its Subsidiaries, including the Principal Subsidiaries, to provide) Mutual
with such cooperation and assistance, documents and other information, without
charge, as it may reasonably request in connection with the pursuit of any
overpayment, refund or credit described in Section 6.20(d).

                  (f) For purposes of this Agreement,

                      (i)      The term "Post-Acquisition Date Tax Period"
                               means, with respect to any period which includes
                               but does not end on the Effective Time, the
                               portion of such period which begins on the
                               Effective Time.

                      (ii)     The term "Pre-Acquisition Date Tax Period" means
                               any of the following periods: (A) any period
                               which begins before and ends on or before the
                               Effective Time; and (B) for any period which
                               includes but does not end on the Effective Time,
                               the portion of such period which ends on the
                               Effective Time.

                      (iii)    "Closing Agreement," as used in this Agreement,
                               shall mean a written and legally binding
                               agreement with a taxing authority relating to
                               Taxes.

                      (iv)     "Taxes," as used in this Agreement, shall mean
                               any federal, state, county, local or foreign
                               taxes, charges, fees, levies, or other

                               Treasury Regulation Section 1.1502-6 (or any

THIS WARRANT AND THE SECURITIES ISSUABLE UPON ITS EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
OR ANY STATE SECURITIES LAW, AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE
DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION UNDER THE SECURITIES
ACT OR IN A TRANSACTION WHICH, IN THE OPINION OF COUNSEL REASONABLY SATISFACTORY
TO COVENTRY HEALTH CARE, INC., IS EXEMPT FROM SUCH REGISTRATION.

                           COVENTRY HEALTH CARE, INC.
                          COMMON STOCK PURCHASE WARRANT

         Attached hereto as Exhibit 1 is a list (the "Option List") of issued
and outstanding options (each, an "Option"), and warrants (each, a "Warrant,"
and together with the Options the "Option Securities") that give the respective
holders thereof the right to acquire shares of Common Stock, par value $0.01 per
share (the "Common Stock"), of COVENTRY HEALTH CARE, INC., a Maryland
corporation (the "Company"). The Option List sets forth the name of each holder
of an Option Security, the date on which such Option Security may be exercised,
the date on which such Option Security expires, and the exercise price per share
of Common Stock issuable upon the exercise of such Option Security. Reference is
made herein to that certain Capital Contribution and Share Exchange Agreement,
dated November 3, 1997 (the "Exchange Agreement"), by and among the Company,
Coventry Corporation, a Tennessee corporation, Principal Mutual Life Insurance
Company, an Iowa mutual insurance company ("Principal Mutual"), Principal
Holding Company, an Iowa corporation, and Principal Health Care, Inc., an Iowa
corporation ("Principal"). Capitalized terms not herein defined shall have the
meanings ascribed thereto in the Exchange Agreement.

         The Company hereby certifies that, for value received, Principal or its
successor or assigns (the "Holder"), is entitled, subject to the terms set forth
below, to purchase from the Company, at any time and from time to time during
the period beginning on the date hereof and ending on the latest date of
expiration set forth on the Option List (the "Exercise Period") for each Option
Security set forth on the Option List (without regard to the actual date of
exercise by the holder of the Option Security), a corresponding number of shares
of Common Stock equal to 66 2/3% of the number of shares of Common Stock
purchasable under such Option Security, at the exercise price set forth on the
Option List for such Option Security but only after such Option Security shall
have been exercised by the holder thereof, provided that in the event any Option
Security shall not have been exercised and shall be cancelled, then the right to
purchase hereunder shall be correspondingly reduced by 66 2/3% of the number of
shares of Common Stock covered by such cancelled option. This Warrant is herein
called the "Principal Warrant."

         1.       EXERCISE OF WARRANT.

                  1.1 Delivery of Exercise Notice. During the Exercise Period,
on or before the fifth business day immediately following the last calendar day
of March, June, September and December during each year of the Exercise Period,
and at least twenty (20) days before any meeting of the Company's shareholders
or any other action involving a vote of the Company's Common Stock, the chief
financial officer of the Company shall deliver to the Holder a written notice
(each, a "Warrant




<PAGE>   2








Notice") that sets forth (i) the number of shares of Common Stock that the
Holder shall thereafter be entitled to purchase, which number shall be equal to
the product of (x) 66 2/3% and (y) the number of shares of Common Stock that
were issued by the Company upon the exercise of any Option Securities since the
last Warrant Notice through the record date for the shareholder meeting or
voting event requiring the immediate Warrant Notice or, in all other cases,
through the period ending thirty (30) days before such Warrant Notice; (ii) the
price per share (the "Notice Price") received by the Company upon such exercise
of each of such Option Securities; and (iii) a description of any Option
Securities that have expired or have been canceled during the same period.

                  1.2 Exercise. The purchase rights evidenced by this Warrant
shall be exercised by the Holder delivering to the Company a written notice
substantially in the form attached as Exhibit 2 hereto (the "Exercise Notice"),
duly executed by such Holder, accompanied by payment (the "Exercise Payment") of
an amount equal to the Notice Price multiplied by the number of shares being
purchased pursuant to such exercise, payable as follows: (a) by payment to the
Company in cash, by check, or by wire transfer of the Exercise Payment, or (b)
by surrender to the Company for cancellation of securities of the Company having
a Market Price (as hereinafter defined) on the date of exercise equal to the
Exercise Payment.

                  For purposes hereof, the term "Market Price" shall mean (a) if
the Common Stock is traded on a national securities exchange, the last reported
sale price of a share of Common Stock, regular way on such date or, in case no
such sale takes place on such date, the average of the closing bid and asked
prices thereof regular way on such date, in either case as officially reported
on the principal national securities exchange on which the Common Stock is then
listed or admitted for trading, or, (b) if the Common Stock is not then listed
or admitted for trading on any national securities exchange but is designated as
a national market system security by the National Association of Securities
Dealers, Inc. ("NASD"), the last reported trading price of the Common Stock on
such date, or (c) if not listed or admitted to trading on any national
securities exchange or designated as a national market system security, the
average of the reported bid and asked price of the Common Stock on such date in
the over-the-counter market as furnished by the National Quotation Bureau, Inc.,
or, if such firm is not then engaged in the business of reporting such prices,
as furnished by any member of the NASD selected by the Company or, (d) if the
shares of Common Stock are not so publicly traded, the fair market value
thereof, as determined in good faith by the Board of Directors of the Company.

         2.       DELIVERY OF STOCK CERTIFICATES ON EXERCISE. As soon as
practicable after any exercise of this Principal Warrant and receipt of the
Exercise Payment, and in any event within ten business days thereafter, the
Company, at its expense, will cause to be issued in the name of and delivered to
the Holder a certificate or certificates for the number of fully paid and
non-assessable shares of Common Stock or property to which such holder shall be
entitled upon such exercise, plus, in lieu of any fractional share to which such
holder would otherwise be entitled, cash in an amount determined in accordance
with Section 3.5 hereof. The Company agrees that the shares

                                       -2-



<PAGE>   3





so purchased shall be deemed to be issued to the holder hereof as the record
owner of such shares as of the close of business on the date the Exercise Notice
shall have been delivered and payment made for such shares as aforesaid.

         3.       OTHER ADJUSTMENTS.  The number of shares of Common Stock
issuable upon exercise of this Principal Warrant shall be subject to adjustment
from time to time in accordance with this Section 3.

                  3.1 Cancellation or Expiration of Option Convertible
Securities. If any Option Security shall expire or shall be canceled without
being exercised, in whole or in part, and any obligation of the Company to issue
shares of Common Stock thereunder shall terminate, then the right of the Holder
to acquire any shares of Common Stock relating to such canceled Option Security
shall immediately terminate and no longer be in effect.

                  3.2 Principal Warrant Adjustment. In the event the Exercise
Price and/or the number of shares underlying any Option Security shall be
adjusted as a result of the anti-dilution rights pertaining to such Option
Security, then this Principal Warrant shall likewise be adjusted with respect to
such Option Security.

                  3.3 Reorganization, Reclassification, Consolidation, Merger or
Sale of Assets. If any capital reorganization or reclassification of the capital
stock of the Company, or consolidation or merger of the Company with another
corporation, or the sale of all or substantially all of its assets to another
corporation shall be effected in such a way that holders of Common Stock shall
be entitled to receive stock, securities, cash or other property with respect to
or in exchange for Common Stock, then, as a condition of such reorganization,
reclassification, consolidation, merger or sale, lawful and adequate provision
shall be made whereby the holder of this Principal Warrant shall have the right
to acquire and receive upon exercise of this Principal Warrant such shares of
stock, securities, cash or other property issuable or payable (as part of the
reorganization, reclassification, consolidation, merger or sale) with respect to
or in exchange for such number of outstanding shares of the Company's Common
Stock (the "Reorganization Consideration") as shall equal the product of (x)
forty percent (40%) and (y) any Reorganization Consideration payable to the
holders of the Option Securities in connection with their ownership of such
Option Securities.

                  3.4 Adjustment by Board of Directors. If any event occurs as
to which, in the opinion of the Board of Directors of the Company, the
provisions of this Section 3 are not strictly applicable or if strictly
applicable would not fairly protect the rights of the holder of this Principal
Warrant in accordance with the essential intent and principles of such
provisions, then the Board of Directors shall make an adjustment in the
application of such provisions, in accordance with such essential intent and
principles, so as to protect such rights as aforesaid.

                  3.5 Fractional Shares. The Company shall not issue fractions
of shares of Common Stock upon exercise of this Principal Warrant or scrip in
lieu thereof. If any fraction of a share of Common Stock would, except for the
provisions of this Section 3.5, be issuable upon exercise of this Principal
Warrant, the Company shall in lieu thereof pay to the person entitled thereto

                                       -3-



<PAGE>   4





an amount in cash equal to the Market Price, calculated to the nearest
one-hundredth (1/100) of a share.

                  3.6 Officer's Statement as to Adjustments. Whenever the number
of shares issuable upon exercise of this Principal Warrant shall be adjusted as
provided in this Section 3, the Company shall deliver to the Holder, a
statement, signed by the Chief Financial Officer of the Company, showing in
reasonable detail an amended and restated Exhibit 1 to this Principal Warrant
that will be effective after such adjustment.

         4.       RESERVATION OF STOCK. The Company shall at all times reserve
and keep available out of its authorized but unissued stock, solely for the
issuance and delivery upon the exercise of this Principal Warrant, such number
of its duly authorized shares of Common Stock as from time to time shall be
issuable upon the exercise of this Principal Warrant.

         5.       REPLACEMENT OF WARRANT. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Principal Warrant and (in the case of loss, theft or destruction) upon
delivery of an indemnity agreement (with surety if reasonably required) in an
amount reasonably satisfactory to it, or (in the case of mutilation) upon
surrender and cancellation thereof, the Company will issue, in lieu thereof, a
new warrant of like tenor.

         6.       REMEDIES.  The Company stipulates that the remedies at law of
the Holder in the event of any default by the Company in the performance of or
compliance with any of the terms of this Principal Warrant are not and will not
be adequate, and that the same may be specifically enforced.

         7.       NEGOTIABILITY, ETC. This Principal Warrant and any shares of
Common Stock issuable under this Principal Warrant may not be sold, pledged,
hypothecated or otherwise transferred except in accordance with the provisions
of that certain Shareholders' Agreement, of even date herewith, by and among the
Company, Principal and Principal Mutual.

         8.       NOTICES. All notices, consents, waivers, and other
communications under this Principal Warrant must be in writing and will be
deemed to have been duly given when (a) delivered by hand (with written
confirmation of receipt), (b) sent by telecopier (with written confirmation of
receipt) provided that a copy is mailed by registered mail, return receipt
requested, or (c) when received by the addressee, if sent by a nationally

         9.       HEADINGS, ETC.  The headings in this Principal Warrant are for
purposes of reference only, and shall not limit or otherwise affect the meaning
hereof.

         10.      CHANGE, WAIVER, ETC.  Neither this Principal Warrant nor any
term hereof may be changed, waived, discharged or terminated orally but only by
an instrument in writing signed by the party against which enforcement of the
change, waiver, discharge or termination is sought.

ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF MARYLAND, WITHOUT REGARD TO

         ANY STATE SECURITIES LAW, AND MAY NOT BE SOLD, TRANSFERRED OR
         OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE
         REGISTRATION UNDER THE ACT OR IN A TRANSACTION WHICH, IN THE
         OPINION OF COUNSEL REASONABLY ACCEPTABLE TO THE COMPANY, IS

         AGREEMENT, DATED [ ], BETWEEN PRINCIPAL MUTUAL LIFE INSURANCE

under the Act, if the Company shall receive an opinion of counsel, from counsel
reasonably acceptable to the Company, that such legend is not required under the

the Company shall:

                  (a) give written notice setting forth in reasonable detail (i)
the designation and all of the terms and provisions of the securities proposed
to be issued (the "Proposed Securities"), including, where applicable, the
voting powers, preferences and relative participating, optional or other special
rights, and the qualification, limitations or restrictions thereof and interest
rate and maturity; (ii) the price and other terms of the proposed sale of such
securities; (iii) the amount of such securities proposed to be issued; and (iv)
such other information as the holders of the Securities may reasonably request
in order to evaluate the proposed issuance;

                  (b) offer to issue to Principal (and/or to any other Mutual
Affiliate which shall own shares of Common Stock) upon the terms described in
subparagraph (a) above a portion of the Proposed Securities (the "Subscription
Securities") equal to a percentage determined by dividing (x) the number of
shares of Common Stock owned by Principal and/or any Mutual Affiliate
immediately preceding the issuance of the Proposed Securities, by (y) the total
number of shares of Common Stock outstanding immediately preceding the issuance
of the Proposed Securities (provided that in no event shall such percentage
exceed 40%).

                  (c) Principal and/or Mutual Affiliate must notify the Company 
of its intent to exercise its purchase rights hereunder within ten (10) days
after receipt of such notice from the Company and purchase the Subscription
Securities upon the closing of the issuance of the Proposed Securities.

                  (d) Upon the expiration of the offering period described 
above, the Company will be free to sell such Subscription Securities that
Principal and/or any Mutual Affiliate has not elected to purchase during the
ninety (90) days following such expiration on terms and conditions no more
favorable to the purchasers thereof than those offered to Principal and/or any
Mutual Affiliate. Any Subscription Securities offered or sold by the Company
after such ninety (90) day period must be reoffered to Principal and/or any
Mutual Affiliate pursuant to this Section 2.

                  (e) The election by Principal and/or any Mutual Affiliate not
to exercise its subscription rights under this Section 2 in any one instance
shall not affect its right (other than in respect of a reduction in its
percentage holdings) as to any subsequent proposed issuance. Any sale of such
securities by the Company without first giving Principal and/or any Mutual
Affiliate the rights described in this Section 2 shall be void and of no force
and effect.

         SECTION 3. EFFECT OF RIGHTS AGREEMENT. At or prior to the Closing, the
Company shall have adopted the Rights Agreement, substantially in the form
attached as Exhibit 8 to the Exchange Agreement, pursuant to which Principal,
Mutual and/or any Mutual Affiliate shall be exempt from the definition of an
"Acquiring Person" (as defined under the Rights Agreement) for so long as none
of Principal, Mutual and/or any Mutual Affiliate has breached in any material
respect, any provision of Sections 1(a) or, 4 of this Agreement while such
sections remain effective, and after such sections shall no longer be effective,
until such time as Mutual and the

                                        3


<PAGE>   4



Mutual Affiliates shall collectively Beneficially Own less than fifteen percent
(15%) of the Common Stock.

         SECTION 4. STANDSTILL. Mutual hereby covenants and agrees that, on or
before the fifth anniversary of the date hereof, it will not, and will cause
Mutual Affiliates to not, without the prior written consent of a majority of the
members of the Company's Board of Directors, do any of the following except
pursuant to Section 2 hereof:

                  (a) acquire, offer or agree to acquire any shares of Common
Stock (or options or warrants to acquire, or securities convertible into or
exchangeable for, shares of Common Stock) if, as a result of such acquisition,
Mutual (together with any Mutual Affiliates) would Beneficially Own more than a
number of shares of Common Stock in excess of a number equal to forty percent
(40%) of the outstanding shares of Common Stock plus forty percent (40%) of the
shares of Common Stock issuable upon conversion of the Convertible Notes plus
forty percent (40%) of the number of shares of Common Stock issuable upon
conversation of the Preferred Stock; provided, however, that, for purposes of
computing such amount, the 29,800 shares of Common Stock Beneficially Owned by
Invista Capital Management, Inc. ("Invista") on November 3, 1997 shall be
excluded from such calculation for as long as such shares are regarded as
Beneficially Owned by Invista (and no longer) and provided that no executive
officer or director of Mutual or Principal or any employee of Mutual, Principal,
or any of their affiliates other than officers, directors or employees of
Invista charged with the responsibility thereof shall participate in the voting
of such shares and provided further that for so long as the Convertible Notes
are outstanding, Mutual and the Mutual Affiliates, in the aggregate, will not
vote or act on written consent in any matter coming before shareholders at any
shareholder meeting or shareholder action in excess of forty percent (40%) of
the shares of Common Stock outstanding plus forty percent (40%) of the shares of
Preferred Stock outstanding;

                  (b) directly or indirectly commence or participate in a
solicitation of proxies either to oppose the election of any Person to the Board
of Directors or to seek the removal of any Person from the Board of Directors,
which Person has been nominated by the Nominating Committee of the Board of
Directors;

                  (c) vote its shares of Common Stock for the election of any
Person to the Board of Directors other than the Persons nominated by the
Nominating Committee of the Board of Directors; or

                  (d) directly or indirectly make or solicit or assist any third
party to make a tender or exchange offer to purchase any shares of Common Stock
or make any public announcement concerning, or submit any written proposal to
the Board of Directors of the Company for a merger, share exchange, acquisition
of substantially all of the assets or similar transaction involving the Company.

         SECTION 5. SUSPENSION OF COVENANTS. The provisions of Section 1(a)(ii)
and 4 hereof shall thereafter cease to apply in the event of any of the
following:

                  (a) the Company issues voting securities in an acquisition by
the Company of another corporation or entity by merger, consolidation, exchange
offer, purchase of substantially all of the assets or stock, or other form of
business combination ("Company Acquisition") to any Person as a result of which
such Person, together with its affiliates, shall own a number of shares of
voting securities that shall equal or exceed the number of such shares owned by
Mutual and the Mutual Affiliates in the aggregate;

                  (b) the number of shares of Common Stock then owned by Mutual
and the Mutual Affiliates, in the aggregate, shall be less than 10% of the then
issued and outstanding shares of Common Stock; or

                  (c) the number of shares of Common Stock then owed by any
Person (other than Warburg, or a Person who acquired a number of shares of
Common Stock in a Company Acquisition which did not equal or exceed the number
of shares owned by Mutual and the Mutual Affiliates in the aggregate, so long as
the Company does not permit such person to acquire additional shares of Common
Stock) and the Affiliates of such Person, in the aggregate, shall be greater
than 15% of the insured and outstanding shares of Common Stock

         SECTION 6. RIGHT TO MATCH OFFER. During such period as Section 4 shall
be effective, in the event a third party makes a bona fide tender or exchange
offer (a "Bona Fide Offer") to purchase a majority of the issued and outstanding
shares of Common Stock or to effect a merger or share exchange in which the
acquisition of substantially all of the assets or similar transaction involving
the Company, then not withstanding the provisions of section 4, Mutual shall be
permitted to make a competing offer (the "Mutual Offer") to the Board of
Directors of the Company. Upon the receipt of any Bona Fide Offer, the Board of
Directors shall establish a special committee (the "Special Committee"),
consisting of members of the Board of Directors that are neither members of the
Company's management nor members of the Board of Directors designated by Mutual
pursuant to the terms of Section 7 hereof. The Special Committee shall determine
whether it is advisable and in the best interest of the Company to solicit
additional offers from any other party or parties, shall retain any legal or
financial advisory services deemed necessary or advisable to assist it in its
analysis of the Bona Fide Offer, the Mutual Offer and any other offers solicited
from third parties by the Company, and shall establish any procedures deemed
necessary or advisable to regulate the process pursuant to which the Company
entertains and analyzes the competing offers. The Special Committee shall
analyze each such offer and shall make a recommendation to the entire Board of
Directors with respect to whether any such offer is one that the Company should
recommend to its shareholders. If the Special Committee shall determine that the
value of the Bona Fide Offer or any other offer solicited from a third party is
greater than the value of the Mutual Offer, then Mutual shall have the
opportunity to amend the Mutual Offer to match or exceed the value of the higher
offer and each of the other parties that has submitted an offer to the Company
shall have the right to submit a revised offer to the

                                        5


<PAGE>   6



Company. If the Special Committee shall determine that, after the Company shall
have received the final offer from each such party, the value of the Mutual
Offer is equal to or greater than any other offer received by the Company and
that the Mutual Offer is advisable and in the best interest of the Company's
shareholders, then, notwithstanding the provisions of Section 4(a) hereof to the
contrary, Mutual shall be permitted to take any action deemed necessary or
convenient to acquire that number of shares of Common Stock as specified in the
Mutual Offer for the terms (including price) set forth in the Mutual Offer.

         SECTION 7. VOTING BY MUTUAL. During such period as Section 4 shall be
effective, in the event that (I) a third party makes a Bona Fide Offer to
purchase all of the issued and outstanding shares of Common Stock or to effect a
merger, share exchange or similar transaction as contemplated in Section 6
hereof and the Special Committee shall determine in accordance with the
procedures set forth in Section 6 that the acceptance of the Bona Fide Offer is
in the best interests of the Company's shareholders or (II) a Special Committee
organized pursuant to the procedures set forth in Section 6 determines that it
is in the best interests of the Company's shareholders for the Company to issue
shares of Common Stock in connection with a Company acquisition and, in
connection with such acquisition the Company a vote of the holder's of the
Company's Common Stock is required by law or by applicable requirements of the
National Association of Securities Dealers, Inc.'s National Market System or any
other securities exchange on which shares of the Common Stock are traded, then,
in either event, Mutual agrees to refrain from voting and to cause each Mutual
Affiliate to refrain from voting all of their shares of Common Stock at any
meeting of the Company's shareholders held for the purpose of considering such
proposal (or, if an approval of shareholders is required by reference to all
shares outstanding, to vote its shares of Common Stock and to cause each Mutual
Affiliate to vote its shares of Common Stock in favor of such proposal) provided
that each of the following conditions set forth below are satisfied at such
time:

                  (a) the date of the shareholders meeting shall be on or after
the date that is eighteen (18) months following the Effective Date and during
the period as Section 4 shall be effective;

                  (b) the Board shall have received the written opinion of a
nationally recognized investment banking firm selected by the Company and
reasonably acceptable to Mutual that the proposed transaction is fair to the
Company and its shareholders from a financial standpoint; and

                  (c) the Company's shareholders (other than Mutual and the
Mutual Affiliates) shall have voted in favor of the proposed transaction by
majority vote;

         SECTION 8. MUTUAL NOMINEES TO BOARD. For so long as Mutual Beneficially
Owns at least 10% (the "Minimum Percentage") of the then issued and outstanding
shares of Common Stock and shall not have breached in any material respect,
without cure, any provision of this Agreement, the Company will (i) nominate and
use its best efforts to cause its shareholders to elect and to retain as
directors on the Board of Directors at least one nominee designated by

                                        6


<PAGE>   7



Mutual for each 6% of the issued and outstanding Common Stock then held by
Mutual (such nominees are collectively hereinafter referred to as the "Mutual
Directors") and (ii) use its best efforts to cause its Board of Directors to
limit the number of members of the Compensation Committee, Audit Committee and
Finance Committee of the Board of Directors to three directors and to cause one
Mutual Director to be appointed as a member of each such committee. Any vacancy
created by the death, disability, retirement or removal of any Mutual Director
on the Board of Directors or on any such committee of the Board of Directors
shall be filled by the Board of Directors in accordance with written
instructions of Mutual. In the event the number of members of the Board of
Directors is increased to more than 15 directors, for so long as Mutual owns the
Minimum Percentage, Mutual shall be entitled to the whole number of Mutual
Directors obtained by multiplying (a) the number of directors on the Board of
Directors (including Mutual Directors) by (b) a fraction, (x) the numerator of
which is equal to the number of shares of Common Stock then beneficially owned
(within the meaning of Rule 13d-3 under the Exchange Act) by Mutual and (y) the
denominator of which is equal to the total number of shares of Common Stock then
issued and outstanding. In the event any calculation of the number of Directors
that Mutual is entitled to designate under this Section 7 shall not produce a
whole number of Mutual Directors, then the number of Mutual Directors shall be
rounded to the nearest whole number (with percentages greater than or equal to
50% being rounded up to the next whole number and percentages less than 50%
being rounded down to the next whole number.) In the event that any of Mutual's
nominees shall fail to be elected to the Board of Directors, the provisions of
Sections 1 (a)(ii) and 4 hereof shall terminate and be of no further force or
effect. In the event that after the expiration of Section 4, Mutual or any of
the affiliates shall take any of the actions specified in Section 4(b) or 4(c),
then the Company's obligations hereunder will cease.

         SECTION 9. REGISTRATION RIGHTS.

         9.1 Definitions. As used in this Section 9:

                  (a) the terms "register," "registered" and "registration"
refer to a registration effected by preparing and filing a registration

amendments filed or required to be filed) and the declaration or ordering of
effectiveness of such registration statement;

                  (b) the term "Registrable Securities" means (i) shares of
Common Stock acquired by Principal under the Exchange Agreement or pursuant to

the provisions of Section 2 hereof;

                  (c) the term "Holder" shall mean any holder of Registrable
Securities;

independent public accountants, fees and disbursements of one counsel for all
the Holders, blue sky fees and expenses and the expense of any special audits or

customarily paid by issuers or sellers of securities, but excluding Selling

                  (f) "Selling Expenses" shall mean all underwriting discounts
and selling commissions applicable to the sale of Registrable Securities and all
fees and disbursements of counsel for each of the Holders other than fees and
expenses of one counsel for all the Holders.

                  (a) Request for Registration. If the Company shall receive
from an Initiating Holder a written request that the Company effect any
registration with respect to all or a part of the Registrable Securities and
specifying the intended method of disposition thereon, the Company will:

                           (i)  give written notice of the proposed
         registration, qualification or compliance to all other Holders of
         Registrable Securities promptly, and in any event within 10 business
         days; and

                           (ii) as soon as practicable, use its diligent best
         efforts to effect such registration as may be so requested (in
         accordance with the intended method thereof as aforesaid) and as would
         permit or facilitate the sale and distribution of all or such portion
         of such Registrable Securities as are specified in such request,
         together with all or such portion of the Registrable Securities of any
         Holder or Holders joining in such request as are specified in a written
         request received by the Company within ten (10) business days after
         written notice from the Company is given under Section 9.2(a)(i) above;
         provided that the Company shall not be obligated to effect, or take any
         action to effect, any such registration pursuant to this Section 9.2:

                           (A) In any particular jurisdiction in which the
                  Company would be required to execute a general consent to
                  service of process in effecting such registration,
                  qualification or compliance, unless the Company is already
                  subject to service in such jurisdiction and except as may be
                  required by the Securities Act or

                                        8


<PAGE>   9



                  applicable rules or regulations thereunder;

                           (B) After the Company has effected four (4) such
                  registrations pursuant to this Section 9.2 and such
                  registrations have been declared or ordered effective and the
                  sales of such Registrable Securities shall have closed;
                  provided that any Holder may participate in any such
                  registration to the extent provided in Section 9.2 if the
                  registration as the result of a request of another Initiating
                  Holder; or

                           (C) The Registrable Securities requested by all
                  Holders to be registered pursuant to such request do not have
                  an anticipated aggregate public offering price (before any
                  underwriting discounts and commissions) of not less than
                  $20,000,000.

                           (D) If in the good faith judgment of the Board based
                  upon the written opinion of a nationally recognized investment
                  banking firm selected by the Company and reasonably acceptable
                  to the Holders, such registration would have a material
                  adverse effect on the market price of the shares of Common
                  Stock, the Company shall have the right to limit the number of
                  Registrable Securities requested by all Holders to be
                  registered pursuant to such request; provided, however, that
                  the Company shall use reasonable commercial efforts to
                  register not less than fifty percent (50%) of the number of
                  Registrable Securities requested to be registered or to
                  facilitate a private sale of such number of Registrable
                  Securities to institutional investors in a manner that would
                  ameliorate the anticipated material adverse effect of any such
                  sale on the market price of the shares of Common Stock;
                  provided, further, that in the event the total number of
                  shares that the Selling Holders (as hereinafter defined) shall
                  request to be registered by the Company equals a number that
                  is equal to or less than twenty percent (20%) of the then
                  outstanding shares of Common Stock, then the provisions of
                  this Subsection (i)(E) shall not apply;

         The registration statement filed pursuant to the request of the
Initiating Holders may, subject to the provisions of Section 9.2(b) below,
include other securities of the Company which are held by Persons who, by virtue
of agreements with the Company, are entitled to include their securities in any
such registration.

                  (b) Underwriting. If the Initiating Holders intend to 
distribute the Registrable Securities covered by their request by means of an
underwriting, they shall so advise the Company as a part of their request made
pursuant to Section 9.2. If holders of securities of the Company other than
Registrable Securities who are entitled, by contract with the Company or
otherwise, to have securities included in such a registration (the "Other
Stockholders") request such inclusion, the Holders shall offer to include the
securities of such Other Stockholders in the underwriting and may condition such
offer on their acceptance of the further applicable provisions of this Section

                                        9

9. The Holders whose shares are to be included in such registration and the
Company shall (together with all Other Stockholders proposing to distribute
their securities through such underwriting) enter into an underwriting agreement
in customary form with the representative of the underwriter or underwriters
selected for such underwriting by the Initiating Holders and reasonably
acceptable to the Company. Notwithstanding any other provision of this Section
9.2, if the representative advises the Holders in writing that marketing factors
require a limitation on the number of shares to be underwritten, the securities
of the Company held by Other Stockholders shall be excluded from such
registration to the extent so required by such limitation. If, after the
exclusion of such shares, further reductions are still required, the number of
shares included in the registration by each Holder shall be reduced on a pro
rata basis (based on the number of shares held by such Holder), by such minimum
number of shares as is necessary to comply with such request. No Registrable
Securities or any other securities excluded from the underwriting by reason of
the underwriter's marketing limitation shall be included in such registration.
If any of the Holders or any Other Stockholder who has requested inclusion in
such registration as provided above disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, the underwriter and the Initiating Holders. The securities so
withdrawn shall also be withdrawn from registration. If the underwriter has not
limited the number of Registrable Securities and securities of the Company held
by Other Shareholders to be underwritten, the Company may include its securities
for its own account in such registration if the representative so agrees and if
the number of Registrable Securities and securities of the Company held by Other
Shareholders which would otherwise have been included in such registration and
underwriting will not thereby be limited.

         9.3 Company Registration.

                  (a) Inclusion in Registration. If the Company shall determine
to register any of its equity securities either for its own account or for the
account of a security holder or holders exercising their respective demand
registration rights, other than a registration relating solely to employee
benefit plans, or a registration relating solely to a SEC Rule 145 transaction,
or a registration on any registration form which does not permit secondary sales
or does not include substantially the same information as would be required to
be included in a registration statement covering the sale of Registrable
Securities, the Company will:

                           (i)  promptly, and in event within 10 business days,
         give to each of the Holders a written notice thereof, its intended
         method of disposition, such Holder's rights under this Section 9.3 and
         a list of the jurisdictions in which the Company intends to attempt to
         qualify such securities under the applicable blue sky or other state
         securities laws; and

                           (ii) include in such registration (and any related
         qualification under blue sky laws or other compliance), and in any
         underwriting involved therein, all the Registrable Securities specified
         in a written request or requests, made by the Holders within fifteen
         (15) days after receipt of the written notice from the Company
         described in

                                       10


<PAGE>   11



         clause (i) above, except as set forth in Section 9.3(b) below. Such
         written request may specify all or a part of the Holders' Registrable
         Securities. No registration effected under this Section 9.3 shall
         relieve the Company of its obligations to effect any registration upon
         request under Section 9.2.

                  (b) Underwriting. If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise each of the Holders as a part of the written notice
given pursuant to Section 9.3(a)(i). In such event, the right of each of the
Holders to registration pursuant to this Section 9.3 shall be conditioned upon
such Holders' participation in such underwriting and the inclusion of such
Holders' Registrable Securities in the underwriting to the extent provided
herein; provided, however, that Mutual shall not be required to participate in
such underwriting if Mutual notifies the Company that it is seeking registration
of its shares solely to enable it to distribute such shares to its shareholders
or holders of mutual interests issued thereby. The Holders whose shares are to
be included in such registration (other than Mutual if it elects not to
participate in such underwriting) shall (together with the Company and the Other
Stockholders distributing their securities through such underwriting) enter into
an underwriting agreement in customary form with the representative of the
underwriter or underwriters selected for underwriting by the Company.
Notwithstanding any other provision of this Section 9.3, if the representative
determines that marketing factors require a limitation on the number of shares
to be underwritten, the representative may (subject to the allocation priority
set forth below) limit the number of Registrable Securities to be included in
the registration and underwriting to not less than fifteen percent (15.0%) of
the securities included therein (based on aggregate market values). The Company
shall so advise all holders of securities requesting registration, and the
number of shares of securities that are entitled to be included in the
registration and underwriting shall be allocated in the following manner: The
securities of the Company held by Other Stockholders of the Company (other than
Registrable Securities and other than securities held by holders who by
contractual right demanded such registration ("Demanding Holders")) shall be
excluded from such registration and underwriting to the extent required by such
limitation, and, if a limitation on the number of shares is still required, the
number of shares that may be included in the registration and underwriting by
each of the Holders and Demanding Holders shall be reduced, on a pro rata basis
(based on the number of shares held by such Holder), by such minimum number of
shares as is necessary to comply with such limitation. If any of the Holders or
any Other Stockholder disapproves of the terms of any such underwriting, such
person may elect to withdraw therefrom by written notice to the Company and the
underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration.

        9.4 Expenses of Registration. All Registration Expenses incurred
in connection with any registration, qualification or compliance pursuant to
this Section 9 shall be borne by the Company, and all Selling Expenses shall be
borne by the persons selling shares so registered pro rata on the basis of the
number of their shares so registered. Notwithstanding the foregoing, if the
Holders request registration pursuant to Section 9.2 and, at the time of such
request, all shares then requested to be sold could be sold pursuant to Rule
144(k) under

                                       11


<PAGE>   12



the Act, then the Company shall not be obligated to pay Registration Expenses of
more than $75,000 in connection with such registration.

         9.5 Registration Procedures. In the case of each registration effected
by the Company pursuant to this Section 9, the Company will keep the Holders, as
applicable, advised in writing as to the initiation of each registration and as
to the completion thereof. At its expense, the Company will:

                  (a) prepare and file with the SEC such appropriate form of
registration statement as shall be selected by the Company, and, in the case of
a registration pursuant to Section as shall be reasonably acceptable to Holders
owning a majority (by number of Registrable Securities) of the Registrable
Securities so to be registered, to effect such registration and thereafter use
its best efforts to cause such registration statement to become effective;
provided, however, that in the case of a registration requested pursuant to
Section 9.2, if the Company shall furnish to the Initiating Holders a
certificate signed by the Chairman of the Board stating that, in the good faith
judgment of the Board, the timing of the disclosure of any information that
would be required to be disclosed in such registration statement would be a
serious detriment to the Company and its shareholders if such disclosure were
made on or before the date the filing of such registration statement would be
required, then the Company shall have one additional period of not more than 60
days within which to file such registration statement;

                  (b) (i) prepare and file with the SEC such amendments to such
registration statement and the prospectus used in connection therewith as may be
necessary to keep such registration statement effective for a period of either
(1) not less than 270 days or, if such registration statement relates to an
underwritten offering, such longer period as in the opinion of counsel for the
underwriters a prospectus is required by law to be delivered in connection with
sales of Registrable Securities by an underwriter or dealer or (2) such shorter
period which will terminate when all of the Registrable Securities covered by
such registration statement have been disposed of in accordance with the
intended method of disposition by the Holders selling Registrable securities
covered by such registration statement (a "Selling Holder") (or other sellers of
securities thereunder)(but in any event not before the expiration of any longer
period required under the Securities Act), and (ii) comply with the provisions
of the Securities Act with respect to the disposition of all Registrable
Securities covered by such registration statement until such time as all of such
securities have been disposed of in accordance with the intended method of
disposition by the Selling Holders (or other sellers of securities thereunder);

                  (c) furnish to each Selling Holder such number of conformed
copies of such registration statement and of each such amendment and supplement
thereto (in each case including all exhibits), such number of copies of the
prospectus contained in such registration statement (including each preliminary
prospectus and any summary prospectus) and any other prospectus filed under the
Securities Act, and such other documents in order to facilitate the

                                       12


<PAGE>   13



disposition of the Registrable Securities owned by such Selling Holder as 
such Selling Holder may reasonably request;

                  (d) use its best efforts to register or qualify such
Registrable Securities and other securities covered by such registration
statement under such other securities or blue sky laws of such jurisdictions as
each Selling Shareholder and each other seller of securities thereunder shall
reasonably request, to keep such registration or qualification in effect for so
long as such registration statement remains in effect, and take any other action
which may be reasonably necessary or advisable to enable such Selling Holder to
consummate the disposition in such jurisdictions of the Registrable Securities
owned by such Selling Holder;

                  (e) use its best efforts to cause all Registrable Securities
and other securities covered by such registration statement to be registered
with or approved by, and make any other necessary registrations or filings with,
all other governmental authorities as may be necessary by virtue of the business
and operations of the Company to enable the Selling Holder and any other sellers
of securities thereunder to consummate the disposition of such Shares;

                  (f) furnish to each Selling Holder a signed counterpart,
addressed to such Selling Holder (and the underwriters, if any) of an opinion of
the Company's counsel and a "cold comfort" letter from the Company's independent
public accountants, each in such form and covering such matters as are
customarily covered in opinions of issuer's counsel and in accountants' letters
delivered to the underwriters in under-written public offerings of securities
and, in the case of the accountants' letter, such other financial matters, and,
in the case of the legal opinion, such other legal matters, as such Selling
Holder may reasonably request;

                  (g) notify each Selling Holder selling Registrable Securities
under such registration statement, at any time when a prospectus relating
thereto is required to be delivered under the Securities Act, upon discovery
that, or upon the happening of any event as a result of which, the prospectus
included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances under which they were made, and at the request of any
such Selling Holder promptly prepare and furnish to such Selling Holder a
reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such securities, such prospectus shall not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances under which they were made;

                  (h) otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC;

                  (i) provide and cause to be maintained a transfer agent and
registrar for all

                                       13


<PAGE>   14



Registrable Securities covered by such registration statement from and after a
date not later than the effective date of such registration statement; and

                  (j) use its best efforts to list all Registrable Securities
covered by such registration statement on each securities exchange on which
similar securities issued by the Company are then listed or on the National
Association of Securities Dealers Automated Quotation System or an
internationally recognized stock exchange.

         9.6 Indemnification.

                  (a) The Company will indemnify each of the Holders, as
applicable, each of its officers, directors and partners, and each person
controlling each of the Holders, with respect to each registration which has
been effected pursuant to this Section 9, and each underwriter, if any, and each
person who controls any underwriter, against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any prospectus, offering circular or other document (including any related
registration statement, notification or the like) incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by the
Company of the Securities Act or any rule or regulation thereunder applicable to
the Company and relating to action or inaction required of the Company in
connection with any such registration, qualification or compliance, and will
reimburse each of the Holders, each of its officers, directors and partners, and
each person controlling each of the Holders, each such underwriter and each
person who controls any such underwriter, for any legal and any other expenses
reasonably incurred in connection with investigating and defending any such
claim, loss, damage, liability or action, provided that the Company will not be
liable in any such case to the extent that any such claim, loss, damage,
liability or expense arises out of or is based on any untrue statement or
omission based upon written information furnished to the Company by the Holders
or underwriter and stated to be specifically for use therein.

                  (b) Each of the Holders will, if Registrable Securities held
by it are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers and each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company or such underwriter, each Other Stockholder and each of their
officers, directors, and partners, and each person controlling such Other
Stockholder against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document made by such Holder,
or any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements by such Holder therein
not misleading, and will reimburse the Company and such Other Stockholders,
directors, officers, partners, persons, underwriters

                                       14


<PAGE>   15



or control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by such Holder for use therein; provided, however, that
the obligations of each of the Holders hereunder shall be limited to an amount
equal to the net proceeds to such Holder of securities sold as contemplated
herein.

                   (c) Each party entitled to indemnification under this
Section 9.6 (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or any
litigation resulting therefrom, shall be approved by the Indemnified Party
(whose approval shall not unreasonably be withheld) and the Indemnified Party
may participate in such defense at such party's expense (unless the Indemnified
Party shall have reasonably concluded that there may be a conflict of interest
between the Indemnifying Party and the Indemnified Party in such action, in
which case the fees and expenses of counsel shall be at the expense of the
Indemnifying Party), and provided, further, that the failure of any Indemnified
Party to give notice as provided herein shall not relieve the Indemnifying Party
of its obligations under this Section 9 unless the Indemnifying Party is
materially prejudiced thereby. No Indemnifying Party, in the defense of any such
claim or litigation shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation. Each Indemnified Party shall furnish such information
regarding itself or the claim in question as an Indemnifying Party may
reasonably request in writing and as shall be reasonably required in connection
with the defense of such claim and litigation resulting therefrom.

                  (d) If the indemnification provided for in this Section 9.6
is held by a court of competent jurisdiction to be unavailable to an Indemnified
Party with respect to any loss, liability, claim, damage or expense referred to
herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified
Party hereunder, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such loss, liability, claim, damage or expense
in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party on the one hand and of the Indemnified Party on the other in
connection with the statements or omissions which resulted in such loss,
liability, claim, damage or expense, as well as any other relevant equitable
considerations. The relative fault of the Indemnifying Party and of the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue (or alleged untrue) statement of a material fact or the
omission (or alleged omission) to state a material fact relates to information
supplied by the Indemnifying Party or by the Indemnified Party and

                                       15


<PAGE>   16



the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

                  (e) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with any underwritten public offering
contemplated by this Agreement are in conflict with the foregoing provisions,
the provisions in such underwriting agreement shall be controlling.

                  (f) The foregoing indemnity agreement of the Company and the
Holders is subject to the condition that, insofar as they relate to any loss,
claim, liability or damage made in a preliminary prospectus but eliminated or
remedied in the amended prospectus on file with the Commission at the time the
registration statement in question becomes effective or the amended prospectus
filed with the Commission pursuant to Commission Rule 424(b) (the "Final
Prospectus"), such indemnity agreement shall not inure to the benefit of any
underwriter if a copy of the Final Prospectus was furnished to the underwriter
and was not furnished to the person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act.

         9.7 Information by the Holders. Each of the Holders holding securities
included in any registration shall furnish to the Company such information
regarding such Holder and the distribution proposed by such Holder as the
Company may reasonably request in writing and as shall be reasonably required in
connection with any registration, qualification or compliance referred to in
this Section 9.

         9.8 Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission which may permit the sale of
restricted securities to the public without registration, the Company agrees to:

                  (a) make and keep public information available as those terms
are understood and defined in Rule 144;

                  (b) use its best efforts to file with the SEC in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act at any time after it has become subject to
such reporting requirements; and

                  (c) so long as the Holder owns any Registrable Securities,
furnish to the Holder upon request, a written statement by the Company as to its
compliance with the reporting requirements of Rule 144 (at any time from and
after ninety (90) days following the effective date of the first registration
statement filed by the Company for an offering of its securities to the general
public), and of the Securities Act and the Exchange Act (at any time after it
has become subject to such reporting requirements), a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents
so filed as the Holder may reasonably request

                                       16


<PAGE>   17



in availing itself of any rule or regulation of the Commission allowing the
Holder to sell any such securities without registration.

         9.9 "Market Stand-off" Agreement.

                  (a) Each of the Holders agrees, if requested by the Company
and an underwriter of Common Stock (or other securities) of the Company, not to
sell or otherwise transfer or dispose of any Common Stock (or other securities)
of the Company held by such Holder during the 90-day period following the
effective date of a registration statement of the Company filed under the
Securities Act, provided that all executive officers and directors of the
Company enter into similar agreements. If requested by the underwriters, the
Holders shall execute a separate agreement to the foregoing effect. The Company
may impose stop-transfer instructions with respect to the shares (or securities)
subject to the foregoing restriction until the end of said 90-day period. The
provisions of this Section 9.8 shall be binding upon any transferee who acquires
Registrable Securities, whether or not such transferee is entitled to the
registration rights provided hereunder.

                  (b) The Company agrees, if requested by the Holders and the
underwriter selected thereby pursuant to Section 9.2(b), not to sell or
otherwise transfer or dispose of any Common Stock (or other securities) of the
Company pursuant to a public offering (other than an offering under Form S-8)
during the 90-day period following the effective date of a registration
statement of the Company filed under the Securities Act in accordance with the
provisions of Section 9.2 hereof, provided that all Holders enter a "stand off"
agreement under Section 9.9(a) hereof.

         9.10 Preparation; Reasonable Investigation. In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the Holders owning Shares to
be registered under such registration statement, their underwriters, if any, and
their respective counsel and accountants (the "Inspectors"), the opportunity to
participate in the preparation of such registration statement, each prospectus
included therein or filed with the SEC, and each amendment or supplement
thereto, and will give each of them such access to its books and records and
such opportunities to discuss the business of the Company with its officers and
the independent public accountants who have certified its financial statements
as shall be necessary, in the opinion of such Holders' and such underwriters'
respective counsel, to conduct a reasonable investigation within the meaning of
the Securities Act. Records which the Company determines in good faith to be
confidential and which it notifies the Inspectors in writing are confidential
shall be treated as confidential by each Inspector in accordance with such
procedures as such Inspector applies generally to information of this kind
unless (a) disclosure of such records is necessary to avoid or correct a
misstatement or omission in the registration statement or any prospectus used in
connection therewith, (b) the information contained in such records has become
generally available to the public, (c) disclosure is required in any report,
statement or testimony required to be submitted to any governments authority
having or claiming to have jurisdiction over such Inspector), or (d) disclosure
is required in response to any summons or subpoena or in connection with any
litigation.

                                       17


<PAGE>   18



         9.11 Adjustment Affecting Shares. The Company will not effect or permit
to occur any combination or subdivision of the Registrable Securities which
would adversely affect the ability of the Holders to include the Registrable
Securities in any registration of its securities contemplated by this Article 9
or the marketability of the Registrable Securities under any such registration.

         9.12 Termination. The registration rights set forth in this Section 9
shall not be available to any Holder if, in the opinion of counsel to the
Company, all of the Registrable Securities then owned by such Holder could be
sold in any 90-day period pursuant to Rule 144 under the Securities Act (without
giving effect to the provisions of Rule 144(k) in the case of a Holder owing
more than three percent (3.0%) of the Common Stock then outstanding).

         9.13 Assignment. The registration rights set forth in this Section 9
shall be assignable, in whole or in part, to any transferee of Common Stock in a
private placement or other unregistered sale (who shall be bound by all
obligations of this Section 9).

         SECTION 10. MISCELLANEOUS.

         10.1 Notices. Any notice required to be given hereunder shall be
sufficient if in writing, and sent by facsimile and by courier service (with
proof of service), hand delivery or certified or registered mail (return receipt
requested and first-class postage prepaid), addressed: (x) if to the Company, at
the Company's principal business address at [ ] or (y) if to Mutual, at the
address of Mutual listed in the stock records of the Company, or (z) to such
other address as any party shall specify by written notice so given, and such
notice shall be deemed to have been delivered as of the date so
telecommunicated, personally delivered or if mailed, the date of receipt.

         10.2 Assignment, Binding Effect; Benefit. Unless expressly provided in
this Agreement, neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto (whether by
operation of law or otherwise) without the prior written consent of the other
parties. Subject to the preceding sentence, this Agreement shall be binding upon
and shall inure to the benefit of the parties hereto and their respective
successors and assigns.

         10.3 Entire Agreement. This Agreement constitutes the entire agreement
among the parties with respect to the subject matter hereof and supersedes all
prior agreements and understandings among the parties with respect thereto. No
addition to or modification of any provision of this Agreement shall be binding
upon any party hereto unless made in writing and signed by all parties hereto.

         10.4 Amendment. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto.


                                       18

         10.5 Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of Maryland, without regard to its
rules of conflict of laws.

         10.6 Headings. Headings of the sections of this Agreement are for the
convenience of the parties only, and shall be given no substantive or
interpretive effect whatsoever.

         10.7 Interpretation. In this Agreement, unless the context otherwise
requires, words describing the singular number shall include the plural and vice
versa, and words denoting any gender shall include all genders and words
denoting natural persons shall include corporations and partnerships and vice
versa.

         10.8 Waivers. Except as provided in this Agreement, no action taken
pursuant to this Agreement, including, without limitation, any investigation by
or on behalf of any party, shall be deemed to constitute a waiver by the party
taking such action of compliance with any representations, warranties, covenants
or agreements contained in this Agreement. The waiver by any party hereto of a
breach of any provision hereunder shall not operate or be construed as a waiver
of any prior or subsequent breach of the same or any other provision hereunder.

         10.9 Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that 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, the provision shall be interpreted
to be only so broad as is enforceable.

         10.10 Enforcement of Agreement. The parties hereto agree that
irreparable damage would occur in the event that any of the provisions of this
