corporation or its shareholders. (b) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law or (c) under
Section 48-18-304 of the Tennessee Business Corporation Act (the "Act"). Any

                           CERTIFICATE OF DESIGNATIONS
                 SERIES A REDEEMABLE CONVERTIBLE PREFERRED STOCK

     The following sections set forth the powers, rights and preferences, and
the qualifications, limitations and restrictions thereof, of the Corporation's
Series A Redeemable Convertible Preferred Stock.

     SECTION 1.     DESIGNATION AND AMOUNT.

     1.1. NUMBER OF SHARES. The designation of the series of Preferred Stock,
$.01 par value per share, provided for herein shall be "Series A Redeemable
Convertible Preferred Stock" (hereinafter referred to as the "Series A
Preferred"), and the number of authorized shares constituting Series A Preferred
is 4,923,077. The shares of Series A Preferred shall only be issued in
connection with the consummation of the transactions contemplated by the Stock
Purchase Agreement dated as of May 20, 1998, by and among the Corporation and
the Investor, as defined therein (the "Purchase Agreement").

     1.2. RESTRICTIONS ON REISSUANCE. All Shares of Series A Preferred redeemed,
purchased or otherwise acquired by the Corporation shall be retired and canceled
and shall be restored to the status of authorized but unissued shares of
Preferred Stock, without designation as to series, and may thereafter be issued,
but not as shares of Series A Preferred.

     1.3. STATED VALUE PER SHARE. The Stated Value Per Share of the Series A
Preferred shall be $3.25.

     1.4. RANK. The Series A Preferred shall with respect to rights upon
liquidation, winding up on dissolution, and redemption rights, rank prior to any
other class or series of capital stock of the Corporation, including all classes
of the Common Stock, par value $0.01 per share, of the Corporation, whether now
existing or hereafter created (the "Common Stock"; all of such classes or series
of capital stock of the Corporation to which the Series A Preferred ranks prior,
including without limitation the Common Stock, and including, without
limitation, junior securities convertible into or exchangeable for other junior
securities or phantom stock representing junior securities, are collectively
referred to herein as "Junior Securities").

     SECTION 2.     DIVIDENDS. Each holder of shares of the Series A Preferred

or if no such record date is established, on the date such dividends are
actually paid.

     SECTION 3.     LIQUIDATION AND REDEMPTION.

     3.1. LIQUIDATION. In the event of any dissolution, liquidation or
winding up of the Corporation, whether voluntary or involuntary (a
"Liquidation"), the holders of shares of Series A Preferred shall be entitled
to receive the Stated Value Per Share out of the assets of the Corporation
legally available for distribution to stockholders (whether representing
capital or surplus), before any payment or distribution shall be made on the
Common Stock or any other Junior Securities (the "Series A Preferred
Liquidation Distribution"). After the Series A Preferred Liquidation
Distribution has been made (as provided above), the remaining assets of the
Corporation available for distribution to stockholders shall be distributed
pro rata among the holders of the Junior Securities. If the assets
distributable to holders of the Series A Preferred upon such dissolution,
liquidation or winding up shall be insufficient to pay cash in an amount
equal to the amount of the Series A Preferred Liquidation Distribution to the
holders of shares of Series A Preferred then such assets or the proceeds
thereof shall be distributed among the holders of the Series A Preferred
ratably in proportion to the respective amounts to which they otherwise would
be entitled. Upon the affirmative vote of the holders of a majority of the
shares of the Series A Preferred outstanding, the sale, conveyance, exchange
or transfer of all or substantially all of the property or assets of the
Corporation, or the consolidation or merger of the Corporation or other
entity (any such event (a "Reorganization Event") will be deemed to be a
Liquidation.

     3.2. REDEMPTION.

          (a)  REDEMPTION AT THE OPTION OF THE HOLDER. At any time on or after
May 20, 2003, upon the written request of any holder of Series A Preferred the
Corporation shall redeem the number of shares of Series A Preferred owned by
such holder that is specified in a notice of redemption delivered by such holder
on or prior to the 30th day preceding the requested redemption date, at a
redemption price per share equal to the Stated Value Per Share. The redemption
price shall be payable in cash.

          (b)  REDEMPTION ON AN INITIAL PUBLIC OFFERING. On the closing date of
the initial offering of capital stock of the Company pursuant to an effective
registration statement under the Securities Act of 1933, the Corporation shall,
at the written request of any holder of the Series A Preferred given within 20
days following written notice from the Company that an offering is reasonably
anticipated, redeem up to one-third of the Series A Preferred then held by such
holder reduced by any shares then held by such holders which are to be included
in the offering as specified in such request at a redemption price per share
equal to the greater of (i) the Stated Value Per Share (appropriately adjusted
for stock splits, stock dividends and combinations) or (ii) the public offering
price per share of the capital stock sold in the public offering (appropriately
adjusted to reflect the then applicable Conversion Price of the Series A
Preferred).

          (c)  REDEMPTION PAYMENT. The Corporation shall pay the redemption
price for the shares of Series A Preferred requested to be redeemed in any such
notice on the date specified in such notice (or such later date upon which the
certificates evidencing the

                                        2
<Page>

shares of Series A Preferred are surrendered to the Corporation) (the
"Redemption Date"). If the funds of the Corporation legally available for
payment of the redemption price of Series A Preferred on any Redemption Date are
insufficient to pay the redemption price for the total number of shares of
Series A Preferred to be redeemed on such date, those funds which are legally
available shall be used to redeem the maximum possible number of such shares
ratably based upon the number of such shares of Series A Preferred requested to
be redeemed by the holders thereof. At any time thereafter when additional funds
of the Corporation are legally available for the redemption of the Series A
Preferred, such funds shall immediately be used to redeem the balance of the
shares of Series A Preferred that the Corporation has become obligated to redeem
on any Redemption Date but which it has not redeemed. On the Redemption Date of
any share of Series A Preferred, all rights of the holder of such share shall
cease, and such share shall be deemed to be no longer outstanding.

     SECTION 4.     VOTING RIGHTS: PROTECTIVE PROVISIONS.

     4.1. VOTING RIGHTS; ELECTION OF DIRECTORS. The holders of the Series A
Preferred shall be entitled to notice of all stockholder meetings in accordance
with the Corporation's bylaws, and except as otherwise required by law, the
holders of the Series A Preferred shall be entitled to vote on all matters
submitted to the stockholders for a vote together with the holders of the Common
Stock, and each share of Series A Preferred (including fractional shares) shall
be entitled to one vote for each whole share of Common Stock that would be
issuable upon conversion of such share on the record date for determining
eligibility to participate in the action being taken. In addition, the holders
of a majority of the then issued and outstanding Series A Preferred (including
fractional shares) voting together as a single class shall have the right to
elect two directors (the "Series A Directors") to the Board of Directors of the
Corporation. Any director who shall have been elected by the holders of the
Series A Preferred may be removed, with or without cause, only by the
affirmative vote of holders of a majority of the Series A Preferred.

     4.2. PROTECTIVE PROVISIONS. In addition to any other voting rights provided
by law, or the provisions hereof, at any time when shares of Series A Preferred
are outstanding, the approval of the holders of record of at least a majority of
the issued and outstanding shares of Series A Preferred, given in writing or by
vote at a meeting, and consenting or voting separately as a single class, shall
be required for the Corporation to:

          (a)  authorize or effect a (i) Reorganization Event or (ii)
Liquidation;

          (b)  amend or repeal any provision of the Corporation's Articles of
Incorporation;

change is not approved by a majority of the Corporation's Board of Directors
which majority includes the Series A Directors;

                                        3
<Page>

          (d)  enter into any agreement, transaction, commitment or arrangement
to incur any indebtedness which is not approved by a majority of the
Corporation's Board of Directors which majority includes the Series A Directors;

          (e)  authorize or effect the payment of dividends on, or the
redemption or repurchase of, any capital stock of the Corporation (other than
(i) the repurchase of stock from employees of the Corporation at the employee's
origin, purchase price or such higher price as is approved by a majority of the
Corporation's Board of Directors which majority includes the Series A Directors
or (ii) the payment of dividends on, or the repurchase or redemption of, shares
of Series A Preferred);

          (f)  enter into any agreement, transaction, commitment or arrangement,
other than a non-binding letter of intent, to acquire the capital stock or
assets, or any other interest in any physician practice or other business entity
which is not approved by a majority of the Corporation's Board of Directors
which majority includes the Series A Directors;

          (g)  authorize or issue additional shares of capital stock which is
not approved by a majority of the Corporation's Board of Directors which

approved by a majority of the Corporation's Board of Directors which majority
include the Series A Directors) of the Corporation's Common Stock then
Outstanding on an As-Converted Basis, to officers, directors, employees or
consultants of the Corporation or its subsidiaries or affiliated practices under
a stock option or equity incentive plan which is approved by the Corporation's
Board of Directors (an "Option Plan"); or

          (g)  authorize or effect an increase in the number of authorized
directors above the number authorized on the Original Issue Date (which the
holders acknowledge is 12).

     SECTION 5.     OPTIONAL CONVERSION.

     5.1. GENERAL.

     At any time and from time to time after the issuance thereof and on or
prior to the Redemption Date, any holder of Series a Preferred may convert all
or any of the shares of Series A Preferred held by such holder into a number of
shares of Common Stock computed by multiplying the number of shares of Series A
Preferred proposed to be converted by the Stated Value Per Share of the Series A
Preferred, and dividing the result by the applicable Conversion Price then in
effect. The initial "Conversion Price" shall be $3.25 per share of Common Stock.
The applicable Conversion Price from time to time in effect is subject to
adjustment as hereinafter provided.

                                        4
<Page>

     5.2. CONVERSION PROCEDURE

          (a)  Any holder of shares of Series A Preferred desiring to convert
any portion thereof into Common Stock shall surrender each certificate
representing one or more shares of such Series A Preferred to be converted, duly
endorsed in favor of the Corporation or in blank and accompanied by proper
instruments of transfer, at the principal business office of the Corporation (or
such other place as may be designated by the Corporation), and shall give
written notice to the Corporation at that office of its [ILLEGIBLE] to convert
the same, setting forth therein the name or names (with the address or
addresses) in which the shares of Common Stock are to be issued. Conversion
shall be effective upon receipt by the Corporation of the notice and the share
certificate or certificates contemplated by the preceding sentence. In case of
(x) the redemption of any shares of Series A Preferred pursuant to Section 3.2,
such right of conversion shall cease and terminate, as to the shares to be
redeemed, on the close of business on the Redemption Date, unless the
Corporation shall thereafter default in the payment of the redemption price for
the shares to be so redeemed or (y) any Liquidation of the Corporation, such
right shall cease and terminate at the close of business on the business day
fixed for payment of the amount distributable to the holders of the Series A
Preferred pursuant to Section 3.1.

          (b)  As soon as possible after a conversion has been effected (but in
any event within three business days), the Corporation shall deliver to the
converting holder:

               (i)  a certificate or certificates representing the number of
shares of Common Stock issuable by reason of such conversion in such name or
names and such denomination or denominations as the converting holder has
specified; and

               (ii) a certificate representing any shares of Series A Preferred
which were represented by the certificate or certificates delivered to the
Corporation in connection with such conversion but which were not converted.

          (c)  The issuance of certificates for shares of Common Stock upon
conversion of Series A Preferred shall be made without charge to the holders of
such Series A Preferred for any issuance tax in respect thereof or other cost
incurred by the Corporation in connection with such conversion and the related
issuance of shares of Common Stock.

          (d)  The Corporation shall not close its books against the transfer of
Series A Preferred or of Common Stock issued or issuable upon conversion of
Series A Preferred in any manner which interferes with the timely conversion of
Series A Preferred. The Corporation shall assist and cooperate (but the
Corporation shall not be required to expand substantial efforts or funds) with
any holder of Series A Preferred required to make any governmental filings or
obtain any governmental approval prior to or in connection with any conversion
of shares of Series A Preferred hereunder (including, without limitation, making
any filings required to be made by the Corporation).

          (e)  If any fractional interest in a share of Common Stock would,
except for the provisions of the subparagraph, be deliverable upon any
conversion of shares of

                                        5
<Page>

a holder's Series A Preferred, the Corporation, in lieu of delivering the
fractional share therefore, shall pay an amount to the holder thereof equal to
an amount bearing the same ratio to the fair market value of a whole share of
Common Stock of the Corporation, as determined in good faith by the
Corporation's Board of Directors, as the fractional interest to which the
stockholder would otherwise be entitled bears to a whole share of Common Stock.

          (f)  The Corporation shall at all times reserve and keep available out
of its authorized but unissued shares of Common Stock, solely for the purpose of
issuance upon the conversion of the Series A Preferred, not less than the number
of shares of Common Stock issuable upon the conversion of all outstanding Series
A Preferred that may then be exercised. All shares of Common Stock which are so
issuable shall, when issued, be duly and validly issued, fully paid and
nonassessable and free from all taxes, liens and charges. The Corporation shall
take all such actions as may be reasonably necessary to ensure that all such
shares of Common Stock may be so issued without violation of any applicable law
or governmental regulation or any requirements of any domestic securities
exchange upon which shares of Common Stock may be listed (except for official
notice of issuance which shall be immediately delivered by the Corporation upon
each such issuance).

     5.3. SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Corporation at any
time subdivides (by any stock split, stock dividend. recapitalization or
otherwise) the outstanding shares of one or more classes of Common Stock into a
greater number of shares, the Conversion Price in effect immediately prior to
such subdivision shall be proportionately decreased to account for such
subdivision, and if the Corporation at any time combines (by reverse stock split
or otherwise) the outstanding shares of one or more classes of Common Stock into
a smaller number of shares, the Conversion Price in effect immediately prior to
such combination shall be proportionately increased.

     5.4. REORGANIZATION, RECLASSIFICATION, CONSOLIDATION MERGER OR SALE. In
connection with any Reorganization Event, the holders of Series A Preferred
shall thereafter have the right to acquire and receive, in lieu of the shares of
Common Stock immediately therefore acquirable and receivable upon the conversion
of such holder's Series A Preferred, such shares of stock, securities, cash or
other assets (or, if not practicably attainable, the reasonable equivalent
thereof) as such holder would have received in connection with such
Reorganization Event if such holder had converted its Series A Preferred
immediately prior to such Reorganization Event. The Corporation shall make
appropriate provisions to ensure that the requirements of the previous sentence
are effected.

     5.5. ADJUSTMENT OF PRICE UPON ISSUANCE OF COMMON STOCK.

     Until May 20, 2001, if and whenever the Corporation shall issue or sell, or
is, in accordance with subparagraphs 5.5(a) through 5.5(g), deemed to have
issued or sold, any shares of Common Stock or other equity securities of the
Corporation or any Option or Convertible Securities for a per share price less
than the applicable Conversion Price for the Series A Preferred immediately
prior to the time of such issue or sale (except for (A) shares issued in
connection with the conversion of Series A Preferred, (B) the issuance of shares
or

                                        6
<Page>

options pursuant to an Option Plan, (C) the issuance of Common Stock or
securities convertible into Common Stock in connection with acquisitions or
affiliations approved by a majority of the Board of Directors which majority
includes the Series A Directors) then, forthwith upon such issue or sale (a
"Dilutive Financing "), the Conversion Price shall be reduced to the price at
which the Corporation issued or sold, or is deemed to have issued or sold the
shares of equity securities in the Dilutive Financing, After May 20, 2001, if
and whenever a Dilutive Financing shall occur, then, forthwith upon the Dilutive
Financing, the Conversion Price shall be reduced by MULTIPLYING the Conversion
Price in effect immediately before the issuance or sale by a fraction, the
numerator of which is the number of shares of Common Stock that are Outstanding
on an As-Converted Basis (as defined below) immediately before the Dilutive
Financing PLUS the number of shares of Common Stock that could be purchased at
the Conversion Price at the time of the Dilutive Financing for the aggregate
consideration paid or payable upon the sale or issuance of Common Stock or other
equity securities in the Dilutive Financing, and the denominator of which is the
number of shares of Common Stock that are Outstanding on an As-Converted Basis
immediately before the Dilutive Financing PLUS the number of shares that are
acquired or to be acquired upon the sale or issuance of the Common Stock and
other equity securities in the Dilutive Financing. For purposes of this Section,
"Outstanding on an As-Converted Basis" immediately before the Dilutive Financing
means the SUM OF (i) all Common Stock issued and outstanding on a fully diluted
basis (including shares issuable upon the exercise of all outstanding Options
and the conversion of all outstanding Convertible Securities) immediately before
the Dilutive Financing PLUS and (ii) all Common Stock that would be issued if
all Series A Preferred were converted hereunder immediately before the Dilutive
Financing

     For purposes of this Section 5.5., the following subparagraphs (a) to (g)
shall also be applicable:

          (a) ISSUANCE OF RIGHTS OR OPTIONS. In case at any time the Corporation
shall in any manner grant any warrants or other rights to subscribe for or to
purchase, or any options for the purchase of, Common Stock or any stock or
security convertible into or exchangeable for Common Stock (such warrants,
rights or options being called "Options" and such convertible or exchangeable
stock or securities being called "Convertible Securities") whether or not such
Options or the right to convert or exchange any such Convertible Securities are
immediately exercisable, and the price per share for which Common Stock is
issuable upon the exercise of such Options or upon the conversion or exchange of
such Convertible Securities (determined by dividing (i) the total amount, if
any, received or receivable by the Corporation as consideration for the granting
of such Options, plus the minimum aggregate amount of additional consideration
payable to the Corporation upon the exercise of all such Options, plus, in the
case of such Options which relate to Convertible Securities, the minimum
aggregate amount of additional consideration, if any, payable upon the issue or
sale of such Convertible Securities and upon the conversion or exchange thereof
by (ii) the total maximum number of shares of Common Stock issuable upon the
exercise of all such Options or upon the conversion or exchange of all such
Convertible Securities issuable upon the exercise of such (Options) shall be
less than the applicable Conversion Price for the Series A Preferred immediately
prior to the time of the granting of

                                        7
<Page>

such Options or Convertible Securities, then the total maximum number of shares
of Common Stock issuable upon the exercise of such Options or upon conversion or
exchange of the total maximum amount of such Convertible Securities issuable
upon the exercise of such Options shall be deemed to have been issued for such
price per share as of the date of granting of such Options or the issuance of
such Convertible Securities and thereafter shall be deemed to be outstanding.
Except as otherwise provided in subparagraph (c), no further adjustment shall be
made to the Conversion Price by reason of the issuance of shares upon the
exercise of such Options.

          (b)  ISSUANCE OF CONVERTIBLE SECURITIES. In case the Corporation shall
in any manner issue or sell any Convertible Securities, whether or not the
rights to exchange or convert any such Convertible Securities are immediately
exercisable, and the price per share for which Common Stock is issuable upon
such conversion or exchange (determined by dividing (i) the total amount
received or receivable by the Corporation as consideration for the issue or sale
of such Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Corporation upon the conversion or
exchange thereof by (ii) the total maximum number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities)
shall be less than the applicable Conversion Price for the Series A Preferred
immediately prior to the time of such issue of sale, then the total maximum
number of shares of Common Stock issuable upon conversion or exchange of all
such Convertible Securities shall be deemed to have been issued for such price
per share as of the date of the issue or sale of such Convertible Securities and
thereafter shall be deemed to be outstanding, provided that except as otherwise
provided in subparagraph (c), no adjustment of any Conversion Price shall be
made upon the actual issue of such Common Stock upon conversion or exchange of
such Convertible Securities and if any such issue or sale of such Convertible
Securities is made upon exercise of any Options to purchase any such Convertible
Securities for which adjustments of any Conversion Price have been or are to be
made pursuant to other provisions of this Section 5.5., no further adjustment of
such Conversion Price shall be made by reason of such issue or sale.

          (c)  CHANGE IN OPTION PRICE OR CONVERSION RATE. Upon the happening of
any of the following events, namely, if the purchase price provided for in any
Option referred to in subparagraph (a), the additional consideration, if any,
payable upon the conversion or exchange of any Convertible Securities referred
to in subparagraph (a) or (b), or the rate at which Convertible Securities
referred to in subparagraph (a) or (b) are convertible into or exchangeable for
Common Stock shall change at any time (including, but not limited to, changes
under or by reason of provisions designed to protect against dilution), the
applicable Conversion Price for the Series A Preferred at the time of such event
shall forthwith be readjusted to the Conversion Price which would have been in
effect at such time had such Options or Convertible Securities still outstanding
provided for such changed purchased price, additional consideration or
conversion rate, as the case may be, at the time initially granted, issued or
sold, but in no event will the Conversion Price be readjusted to an amount
greater to the Conversion Price which would have been in effect had the Options
or Convertible Securities subject to the above described consideration changes
never been granted, issued or sold; and on the expiration or exchange of such
Option or Convertible Securities, the

                                        8

Conversion Price then in effect hereunder shall forthwith be increased to the
Conversion Price which would have been in effect at the time of such expiration
or termination had such Option or Convertible Securities, to the extent
outstanding immediately prior to such expiration or termination, never been
issued; PROVIDED, that any consideration which was actually received by the
Corporation in connection with the issuance or sale of such Options or
Convertible Securities shall be included in the readjustment computation even
though such Options or Convertible Securities shall have expired or terminated.

          (d)  CONSIDERATION FOR STOCK. In case any shares of Common Stock,
Options or Convertible Securities shall be issued or sold for cash, the
consideration received therefor shall be deemed to be the amount received by the
Corporation therefor, without deduction therefrom of any amounts paid or
receivable for accrued interest or accrued dividends and any expenses incurred
or any underwriting commissions or concessions paid or allowed by the
Corporation in connection therewith. In case any shares of Common Stock, Options
or Convertible Securities shall be issued or sold for a consideration other than
cash, the amount of the consideration other than cash received by the
Corporation shall be deemed to be the fair value of such consideration as
determined in good faith by the Board of Directors of the Corporation, without
deduction of any amounts paid or receivable for accrued interest or accrued
dividends and any expenses incurred or any underwriting commission or
concessions paid or allowed by the Corporation in connection therewith. In case
any Options shall be issued in connection with the issue and sale of other
securities of the Corporation, together comprising one integral transaction in
which no specific consideration is allocated to such Options by the parties
thereto, such Options shall be deemed to have been issued for such consideration
as determined in good faith by the Board of Directors of the Corporation.

          (e) RECORD DATE. In case the Corporation shall take a record of the
holders of its Common Stock for the purpose of entitling them (i) to receive a
dividend or other distribution payable in Common Stock, Options or Convertible
Securities or (ii) to subscribe for or purchase Common Stock Options or
Convertible Securities, then such record date shall be deemed to be the date of
the issue or sale of the shares of Common Stock deemed to have been issued or
sold upon the declaration of such divided or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

          (f)  TREASURY SHARES. The disposition of any shares of Common Stock
owned or held by or for the account of the Corporation shall be considered an
issue or sale of Common Stock for the purpose of this Section 5.5., but while
held as Treasury Shares shall not be included in the number of shares of Common
Stock outstanding.

     5.6. NOTICES.

          (a)  Immediately upon any adjustment of the Conversion Price, the
Corporation shall give written notice thereof to all holders of Series A
Preferred,setting forth in reasonable detail and certifying the calculation of
such adjustment.

          (b)  The Corporation shall give written notice to all holders of

dividend or distribution upon Common Stock, (ii) with respect to any pro rata
subscription offer to holders of Common Stock or (iii) for determining rights to
vote with respect to any Liquidation or Reorganization Event.

     SECTION 6.     MANDATORY CONVERSION. Each share of Series A Preferred shall
automatically be converted into shares of Common Stock at the then effective
Conversion Price immediately prior to the closing of an underwritten public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended, covering the offer and sale of Common Stock for the
account of the Corporation to the public resulting in gross proceeds to the
Corporation of not less than $25,000,000.

     SECTION 7.     REGISTRATION OF TRANSFER.

     The Corporation shall keep at its principal office a register for the
registration of issuance and transfers of Series A Preferred. Upon the surrender
of any certificate representing Series A Preferred at such place, the
Corporation shall, at the request of the record holder of such certificate,
execute and deliver (at the Corporation's expense) a new certificate or
certificates in exchange therefor representing in the aggregate the number of
shares of Series A Preferred represented by the surrendered certificate. Each
such new certificate shall be registered in such name and shall represent such
number of shares of Series A Preferred as is requested by the holder of the
surrendered certificate and shall be substantially identical in form to the
surrendered certificate, and dividends shall accrue on the Series A Preferred
represented by such new certificate from the date to which dividends have been
fully paid on such Series A Preferred represented by the surrendered
certificate.

     SECTIONS 8.    REPLACEMENT.

     Upon receipt of evidence reasonably satisfactory to the Corporation (an
affidavit of the registered holder shall be satisfactory) of the ownership and
the loss, theft, destruction or mutilation of any certificate evidencing shares
of Series A Preferred, and in the case of any such loss, theft or destruction,
upon receipt of indemnity reasonably satisfactory to the Corporation (provided
that if the holder is a financial institution or other institutional investor,
its own agreement shall be satisfactory), or, in the case of any such mutilation
upon surrender of such certificate, the Corporation shall (at its expense)
execute and deliver in lieu of such certificate a new certificate of like kind
representing the number of shares of Series A Preferred represented by such
lost, stolen destroyed or mutilated certificate and dated the date of such lost,
stolen, destroyed or mutilated certificate, and dividends shall accrue on the
Series A Preferred represented by such new certificate from the date to which
dividends have been fully paid on the shares of Series A Preferred represented

stockholder of AMP. The procedure with respect to fractional shares is set forth

distributions with respect to AMP Common Stock.
