conversion by the Corporation in accordance with the terms hereof, or the

or a portion of the principal amount of the indebtedness evidenced by this Note
into Conversion Shares.

                  (b) The principal amount of the indebtedness evidenced by this
Note or any portion of the principal amount of the indebtedness evidenced hereby
that is One Thousand Dollars ($1,000), an integral multiple of One Thousand

evidenced by this Note is to be converted, the portion thereof to be converted.

Holder wishes the certificate or certificates for shares of Common Stock to be
issued. In case such notice shall specify a name or names other than that of the

(other than taxes based on income) that may be payable in respect of any issue
or delivery of shares of Common Stock on conversion of the indebtedness
evidenced by this Note. No payment or adjustment shall be made upon any
conversion of this Note on account of any dividends or other distributions
payable on the Conversion Shares; provided, however, that the Holder shall be
entitled to receive the full amount of any dividends or other distributions
declared with respect to the Conversion Shares with a record date on or after
the effective date of such conversion.

                  As promptly as practicable, and in any event within five (5)
Business Days after the surrender of this Note and the receipt of such notice
relating thereto and, if applicable, payment of all transfer taxes (or the
demonstration to the satisfaction of the Corporation that such taxes have



                                        6

been paid), the Corporation shall deliver or cause to be delivered, either by
personal delivery or by certified or registered mail or by a recognized
overnight courier service, in any such case, properly insured, to the Holder in
accordance with the written instructions of the Holder (i) certificates
representing the number of Conversion Shares to which the Holder shall be
entitled, and (ii) if less than the entire principal amount of indebtedness
evidenced by this Note, for the balance of the indebtedness that is not being so
converted. Such conversion shall be deemed to have been made at the close of
business on the date of giving such notice and of such surrender of this Note so
that the rights of the Holder (as a noteholder) with respect to the principal
amount being converted shall cease, and the person or persons entitled to
receive the Conversion Shares issuable upon conversion shall be treated for all
purposes as the record holder or holders of such Common Stock as of such day.
All accrued but unpaid interest through the Business Day immediately preceding
the date of such conversion with respect to the principal amount of the
indebtedness evidenced by this Note being converted shall be payable upon
conversion.

                  The Corporation shall not be required to convert, and no
surrender of this Note shall be effective for that purpose, while the transfer
books of the Corporation for the Common Stock are closed for any purpose (but
not for any period in excess of 15 days); but the surrender of this Note for
conversion during any period while such books are so closed shall become
effective for conversion immediately upon the reopening of such books, as if the
conversion had been made on the date this Note is surrendered, and at the
Conversion Ratio in effect at the date of such surrender.

                  (d) In case this Note is to be prepaid pursuant to the
mandatory prepayment provisions hereof, such right of conversion shall cease and
terminate as to the portion of this Note that is to be prepaid at the close of
business on the Business Day next preceding the date fixed for mandatory
prepayment unless the Corporation shall default in the payment of the Mandatory
Prepayment Amount.

                  (e) In connection with the conversion of the indebtedness
evidenced by this Note, no fractions of shares of Common Stock shall be issued,
but in lieu thereof the Corporation shall pay a cash adjustment in respect of
such fractional interest in an amount equal to such fractional interest
multiplied by the Current Market Price per share of Common Stock on the Trading
Day on which such indebtedness evidenced by this Note is deemed to have been
converted. If more than one note shall be surrendered for conversion by the
Holder at the same time, the number of full shares of Common Stock issuable on
conversion thereof shall be computed on the basis of the total amount of
indebtedness to be converted.

                  (f) (i) The Corporation shall at all times reserve and keep
available for issuance upon the conversion of the indebtedness evidenced by this
Note, free from any preemptive rights, such number of its authorized but
unissued shares of Common Stock as will from time to time be sufficient to
permit the conversion of all of the indebtedness evidenced by this Note, and
shall take all action required to increase the authorized number of shares of
Common Stock if necessary to permit the conversion of all of the indebtedness
evidenced by this Note.

                           (ii) If the Corporation shall issue shares of Common
Stock upon conversion of indebtedness evidenced by this Note as contemplated by
this Section 3, the Corporation shall issue together with each such share of
Common Stock any rights issued to holders of Common Stock of the Corporation,
irrespective of whether such rights shall be exercisable at such time, but only
if such rights are issued and outstanding and held by other holders of Common
Stock of the Corporation at such time and have not expired.

                  (g) The Conversion Ratio will be subject to adjustment from
time to time as follows:

                           (i) In case the Corporation shall at any time or from
time to time after the Closing Date (A) pay a dividend, or make a distribution,
on the outstanding shares of Common Stock in shares of Common Stock, (B)
subdivide the outstanding shares of Common Stock, (C) combine the outstanding
shares of Common Stock into a smaller number of shares, or (D) issue by
reclassification of the shares of Common Stock any shares of capital stock of
the Corporation, then, and in each such case, the Conversion Ratio in effect
immediately prior to such event or the record date therefor, whichever is
earlier, shall be adjusted so that the Holder shall be entitled to receive the
number of shares of Common Stock (or other capital stock) of the Corporation
that the Holder would have owned or have been entitled to receive after the
happening of any of the events described above, had the indebtedness evidenced
by this Note been converted immediately prior to the happening of such event or
the record date therefor, whichever is earlier. An adjustment made pursuant to
this clause (i) shall become effective (x) in the case of any such dividend or
distribution, immediately after the close of business on the record date for the
determination of holders of shares of Common Stock entitled to receive such
dividend or distribution, or (y) in the case of such subdivision,
reclassification, or combination, at the close of business on the day upon which
such corporate action becomes effective. No adjustment shall be made pursuant to
this clause (i) in connection with any transaction to which subsection (h)
applies.

                           (ii) In case the Corporation shall issue shares of
Common Stock (or rights, warrants, or other securities convertible into or
exchangeable for shares of Common Stock) after the Closing Date at a price per
share (or having a conversion price per share) less than the Current Market
Price per share of Common Stock, as of the date of issuance of such shares or of
such convertible securities, then, and in each such case, the Conversion Ratio
shall be adjusted so that the Holder shall be entitled to receive, upon the
conversion hereof, the number of shares of Common Stock determined by
multiplying (A) the applicable Conversion Ratio on the day immediately prior to
such date by (B) a fraction, the numerator of which shall be the sum of (1) the
number of shares of Common Stock outstanding on such date plus (2) the number of
additional shares of Common Stock issued (or into which the convertible
securities may convert), and the denominator of which shall be the sum of (x)
the number of shares of Common Stock purchasable at the then Current Market
Price per share with the aggregate consideration received or receivable by the
Corporation for the total number of shares of Common Stock so issued (or into
which the rights, warrants, or other convertible securities may convert).

                           An adjustment made pursuant to this clause (ii) shall
be made on the next Business Day following the date on which any such issuance
is made and shall be effective retroactively to the close of business on the
date of such issuance. For purposes of this clause (ii), the aggregate
consideration received or receivable by the Corporation in connection with the
issuance of shares of Common Stock shall be deemed to be equal to the sum of the
aggregate offering price (before deduction of underwriting discounts or
commissions and expenses payable to third parties) of all such Common Stock,
rights, warrants, and convertible securities plus the minimum aggregate amount,
if any, payable upon exercise of conversion of any such rights, warrants, and
convertible securities into shares of Common Stock. The issuance of any shares
of Common Stock (whether treasury shares or newly issued shares) pursuant to (a)
a dividend or distribution on, or subdivision, combination or reclassification
of, the outstanding shares of Common Stock requiring an adjustment in the
conversion ratio pursuant to clause (i) of this subsection (g), or (b) any
restricted stock or stock option plan or program of the Corporation, or (c) any
option, warrant, right, or convertible security outstanding as of the date
hereof, or (d) the terms of a firmly committed underwritten public offering,
shall not be deemed to constitute an issuance of Common Stock or convertible
securities by the Corporation to which this clause (ii) applies.

                           Upon the expiration of any unexercised options,
warrants, or rights to convert any convertible securities for which an
adjustment has been made pursuant to this clause (ii), the adjustment shall
forthwith be reversed to effect such rate of conversion as would have been in
effect at the time of such expiration or termination had such options, warrant,
rights or convertible securities, to the extent outstanding immediately prior to
such expiration or termination, never been issued. If the purchase price
provided for in any option, warrant, or rights to convert any convertible
securities for which an adjustment has been made pursuant to this clause (ii),
the additional consideration, if any, payable upon the conversion or exchange of
any convertible securities for which an adjustment has been made, or the rate at
which any convertible securities referred to above are convertible into or
exchangeable for Common Stock shall, at any time, increase or decrease (other
than under or by reason of provisions designed to protect against dilution),
then, the Conversion Ratio in effect at the time of such event shall forthwith
be readjusted to the Conversion Ratio that would have been in effect at such
time and such options, warrants, or rights or convertible securities still
outstanding provided for such changed purchase price, additional consideration,
or conversion rate, as the case may be, at the time initially granted, issued or
sold. No adjustment shall be made pursuant to this clause (ii) in connection
with any transaction to which subsection h applies.

                           (iii) In case the Corporation shall at any time or
from time to time after the Closing Date declare, order, pay, or make a dividend
or other distribution (including, without limitation, any distribution of stock
or other securities or property or rights or warrants to subscribe for
securities of the Corporation or any of its subsidiaries by way of dividend or
spinoff), on its Common Stock, other than (A) dividends payable in cash in an
aggregate amount not to exceed 50% of net income from continuing operations
before extraordinary items of the Corporation, determined in accordance with
generally accepted accounting principles, during the period (treated as one
accounting period) commencing on March 31, 1992, and ending on the date such
dividend is paid; provided, that, to the extent required by the terms thereof,
such dividend shall have been previously



                                        9

   10



consented to by the holders of the notes issued pursuant to the Note Purchase
Agreement, or (B) dividends or distributions of shares of Common Stock which are
referred to in clause (i) of this subsection (g), then, and in each such case,
the Conversion Ratio shall be adjusted so that the Holder shall be entitled to
receive, upon the conversion hereof, the number of shares of Common Stock
determined by multiplying (1) the applicable Conversion Ratio on the day
immediately prior to the record date fixed for the determination of stockholders
entitled to receive such dividend or distribution by (2) a fraction, the
numerator of which shall be the Current Market Price per share of Common Stock
for the period of 20 Trading Days preceding such record date, and the
denominator of which shall be such Current Market Price per share of Common
Stock less the fair market value, as determined in good faith by the Board, a
certified resolution with respect to which shall be mailed to the Holder, per
share of Common Stock of such dividend or distribution. No adjustment shall be
made pursuant to this clause (iii) in connection with any transaction to which
subsection (h) applies.

                           (iv) For purposes of this subsection (g), the number
of shares of Common Stock at any time outstanding shall not include any shares
of Common Stock then owned or held by or for the account of the Corporation.

                           (v) The term "dividend," as used in this subsection
(g), shall mean a dividend or other distribution upon stock of the Corporation.

                           (vi) Anything in this subsection (g) to the contrary
notwithstanding, the Corporation shall not be required to give effect to any
adjustment in the Conversion Ratio unless and until the net effect of one or
more adjustments (each of which shall be carried forward), determined as above
provided, shall have resulted in a change of the Conversion Ratio by at least
one one-hundredth (.01) of one share of Common Stock, and when the cumulative
net effect of more than one adjustment so determined shall be to change the
Conversion Ratio by at least one one-hundredth (.01) of one share of Common
Stock, such change in Conversion Ratio shall thereupon be given effect.

                           (vii) The certificate of any firm of independent
public accountants of recognized standing selected by the Board (which may be
the firm of independent public accountants regularly employed by the
Corporation) shall be presumptively correct for any computation made under this
subsection (g).

                           (viii) If the Corporation shall take a record of the
holders of its Common Stock for the purpose of entitling them to receive a
dividend or other distribution, and shall thereafter and before the distribution
to stockholders thereof legally abandon its plan to pay or deliver such dividend
or distribution, then thereafter no adjustment in the number of shares of Common
Stock issuable upon exercise of the right of conversion granted by this
subsection (g) or in the Conversion Ratio then in effect shall be required by
reason of the taking of such record.

                  (h) In the case of any Major Transaction occurring at any
time, at the option of the Holder, the indebtedness evidenced by the Note shall
thereafter be convertible into, in whole and in



                                       10

   11



part and in lieu of the Common Stock issuable upon such conversion prior to
consummation of such Major Transaction, the kind and amount of shares of stock
and other securities and property receivable (including cash) upon the
consummation of such Major Transaction by a holder of that number of shares of
Common Stock into which such indebtedness, or portion thereof, was convertible
immediately prior to such Major Transaction (including, on a pro rata basis, the
cash, securities, or property received by holders of Common Stock in any tender
or exchange offer that is a step in such Major Transaction). In case securities
or property other than Common Stock shall be issuable or deliverable upon
conversion as aforesaid, then all references in this Section 3 shall be deemed
to apply, so far as appropriate and nearly as may be, to such other securities
or property.

                  (i) In case at any time or from time to time the Corporation
shall pay any stock dividend or make any other non-cash distribution of the
holders of its Common Stock, or shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other right, or there shall be any capital reorganization or reclassification of
the Common Stock of the Corporation or consolidation or merger of the
Corporation with or into another corporation or other entity, or any sale or
conveyance to another corporation or other entity of the assets or property of
the Corporation as an entirety or substantially as an entirety, or there shall
be a voluntary or involuntary dissolution, liquidation, or winding up of the
Corporation, then, in any one or more of said cases the Corporation shall give
at least 20 days prior written notice (the time of mailing of such notice shall
be deemed to be the time of giving thereof) to the Holder at the address of the
Holder as shown on the books of the Corporation as of the date of which (i) the
books of the Corporation shall close or a record shall be taken for such stock
dividend, distribution, or subscription rights, or (ii) such reorganization,
reclassification, consolidation, merger, sale, conveyance, dissolution,
liquidation, or winding up shall take place, as the case may be, provided that
in the case of any Major Transaction to which subsection (h) applies the
Corporation shall give at least 30 days prior written notice as aforesaid. Such
notice shall also specify the date as of which the holders of the Common Stock
of record shall participate in said dividend, distribution, or subscription
rights or shall be entitled to exchange their Common Stock for securities or
other property deliverable upon such reorganization, reclassification,
consolidation, merger, sale, or conveyance or participate in such dissolution,
liquidation, or winding up, as the case may be. Failure to give such notice
shall not invalidate any action so taken.

                  (j) Anything herein to the contrary notwithstanding, the
issuance or sale of the following shares of Common Stock or options, warrants,
or other rights to purchase Common Stock shall be excluded from any calculation
of, and shall not be deemed issued or sold for purposes of calculating, any
reduction, adjustment, or readjustment of the Conversion Ratio hereunder: (i)
shares of Common Stock issued upon conversion of the indebtedness evidenced by
this Note or any portion thereof; (ii) shares of Common Stock or options,
warrants, or other rights to purchase Common Stock issuable, reserved for
issuance, or issued pursuant to a stock option plan, employee stock ownership
plan, or other compensatory benefit plan of the Corporation, duly adopted by the
Board; (iii) shares of Common Stock, issuable, reserved for issuance, or issued
pursuant to any currently outstanding warrants or options, or any options,
warrants, or other rights issuable, reserved for issuance, or issued to officers
of the Corporation in the future for compensatory purposes, if fully



                                       11

   12



authorized by the Board; and (iv) shares of Common Stock issued upon conversion
of the indebtedness evidenced by the Convertible Notes or the currently issued
and outstanding preferred stock.

                  SECTION 4. REPORTS AS TO ADJUSTMENTS. Upon any adjustment of
the Conversion Ratio then in effect and any increase or decrease in the number
of shares of Common Stock issuable upon the operation of the conversion set
forth in Section 3, then, and in each such case, the Corporation shall promptly
deliver to the Holder, a certificate signed by the President or a Vice President
and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant
Secretary of the Corporation setting forth in reasonable detail the event
requiring the adjustment and the method by which such adjustment was calculated
and specifying the Conversion Ratio then in effect following such adjustment and
the increased or decreased number of shares issuable upon the conversion granted
by Section 3, and shall set forth in reasonable detail the method of calculation
of each and a brief statement of the facts requiring such adjustment. Where
appropriate, such notice to the Holder may be given in advance and included as
part of the notice required under the provisions of Section 3(i).

                  SECTION 5. MANDATORY CONVERSION. (a) At any time after June
22, 1997, and so long as at such time the Common Stock is listed or admitted to
trading on a national securities exchange, the Corporation may require the
Holder to convert all or a portion of the principal amount of the indebtedness
evidenced by this Note into shares of Common Stock if, at such time, the Current
Market Price of the Common Stock has equalled or exceeded one hundred fifty
percent (150%) of the Conversion Price (as it may from time to time be adjusted)
for forty-five (45) consecutive Trading Days following the forty-fifth monthly
anniversary of the Closing Date. To exercise such right, the Corporation must
deliver a Mandatory Conversion Notice of the exercise of such right to the
Holder within thirty (30) days of the last day of such forty-five (45) day
period, such Mandatory Conversion Notice must be given at least ten (10)
Business Days, but not more than fifteen (15) Business Days prior to the
proposed Mandatory Conversion Date, and such Mandatory Conversion Notice must
specify the proposed Mandatory Conversion Date and the portion of the principal
amount of the indebtedness evidenced by this Note to be converted into Common
Stock.

                  (b) All conversions effected pursuant to the preceding
paragraph will be made effective as of the close of business on the Mandatory
Conversion Date at the Conversion Ratio in effect on the Mandatory Conversion
Date; provided, however, that, in order to be able to convert, the Current
Market Price on the Mandatory Conversion Date must equal or exceed one hundred
fifty percent (150%) of the Conversion Price in effect on the Mandatory
Conversion Date. If the Current Market Price on the Mandatory Conversion Date
does not equal or exceed one hundred fifty percent (150%) of the Conversion
Price in effect on the Mandatory Conversion Date, the Corporation's election to
require conversion will be deemed void and no conversion will be effected
pursuant to such notice. Such event will not be deemed, however, to alter or
restrict the Corporation's right to again require conversion at such time as the
Current Market Price equals or exceeds one hundred fifty percent (150%) of the
then current Conversion Price for forty-five (45) consecutive Trading Days prior
to such time. Upon conversion required by the Corporation pursuant to this
paragraph



                                       12

   13



and the immediately preceding paragraph, all accrued but unpaid interest with
respect to the principal amount of the indebtedness evidenced by this Note being
converted shall be payable in accordance with the provisions of the following
paragraph.

                  (c) Conversions of the indebtedness evidenced by this Note
effected by the exercise of the Corporation's right to require conversion will
be deemed effective as of the close of business on the Mandatory Conversion Date
without any action by the Holder and the Holder will, as of such time, be a
stockholder of the Corporation with respect to the number of shares of Common
Stock into which the principal balance evidenced by this Note (or such portion
of the principal balance evidenced by this Note as the Corporation shall have
specified) shall have been converted. The Holder agrees promptly to surrender
this Note for cancellation following mandatory conversion. Certificates
representing the shares of Common Stock issuable by the Corporation as a result
of the mandatory conversion of all or a portion of the principal balance of the
indebtedness evidenced by this Note and all dividends and other distributions
payable with respect to such shares and all accrued but unpaid interest payable
pursuant to the immediately preceding paragraph will be retained by the
Corporation pending surrender of this Note for cancellation. As promptly as
practicable, and in any event within five (5) Business Days after the surrender
of this Note, the Corporation shall deliver or cause to be delivered, either by
personal delivery or by certified or registered mail or by a recognized
overnight courier service, in any such case, properly insured, to the Holder in
accordance with the written instructions of the Holder (i) certificates
representing the number of Conversion Shares to which the Holder shall be
entitled, and (ii) if less than the entire principal amount of indebtedness
evidenced by this Note is being converted, a new promissory note, in the form of
this Note, for the balance of the indebtedness that is not being so converted.

                  (d) In connection with the conversion of the indebtedness
evidenced by this Note, no fractions of shares of Common Stock shall be issued,
but in lieu thereof the Corporation shall pay a cash adjustment in respect of
such fractional interest in an amount equal to such fractional interest
multiplied by the Current Market Price per share of Common Stock on the Trading
Day on which such indebtedness evidenced by this Note is deemed to have been
converted. If more than one note shall be surrendered for conversion by the
Holder at the same time, the number of full shares of Common Stock issuable on
conversion thereof shall be computed on the basis of the total amount of
indebtedness to be converted.

                  SECTION 6. MANDATORY PREPAYMENT. In the case of any Change
Event occurring at any time, at the option of the Holder, the Holder may require
the Corporation to prepay all or a portion of the then outstanding principal
amount of the indebtedness evidenced by this Note. To exercise such right of
prepayment, the Holder must provide the Corporation with a Mandatory Prepayment
Notice at least thirty (30) days prior to the proposed Mandatory Prepayment Date
which Mandatory Prepayment Notice shall specify the portion of the principal
amount of the indebtedness evidenced by this Note (which must be in integral
multiples of One Thousand Dollars ($1,000)) to be prepaid. On the Mandatory
Prepayment Date specified, the Corporation shall prepay the portion of the
principal amount of the indebtedness evidenced by this Note that the Holder has
specified must be prepaid on such date, plus accrued interest on such principal
amount to the date of the



                                       13

   14



prepayment. Any prepayment shall be made by cashiers check or by wire transfer
of immediately available funds, in currency of the United States of America as
at the time of payment is legal tender for payment of public and private debts,
at such address or to such account, as applicable, as shall be designated to the
Corporation by the Holder.

                  SECTION 7. OPTIONAL PREPAYMENT. The Note shall be subject to
prepayment, at the option of the Corporation, at any time and from time to time
on and after July 1, 1997. To exercise such right of prepayment, the Corporation
must provide the Holder with an Optional Prepayment Notice at least sixty (60)
days prior to the proposed Optional Prepayment Date which Optional Prepayment
Notice shall specify the portion of the principal amount of the indebtedness
evidenced by this Note (which must be in integral multiples of One Thousand
Dollars ($1,000)) to be prepaid. The Holder's option to convert the indebtedness
evidenced by this Note as set forth in Section 3 hereof shall continue
notwithstanding the exercise of the option of the Corporation to prepay under
this Section 7, so long as the Holder requests conversion in accordance with the
terms hereof up to and including, but not after, the close of business on the
third Business Day prior to the Optional Prepayment Date. On the Optional
Prepayment Date specified, the Corporation shall prepay the portion of the
principal amount of the indebtedness evidenced by this Note that the Corporation
has specified is to be prepaid on such date, plus accrued interest on such
principal amount to the date of the prepayment. Any prepayment shall be made by
cashiers check or by wire transfer of immediately available funds, in currency
of the United States of America as at the time of payment is legal tender for
payment of public and private debts, at such address or to such account, as
applicable, as shall be designated to the Corporation by the Holder. This Note
shall not be subject to prepayment, whether in whole or in part, on or before
June 30, 1997.

                  SECTION 8. SUBORDINATION. (a) The Corporation covenants and
agrees, and the Holder likewise covenants and agrees, that no payment shall be
made by the Corporation on account of principal of or interest on this Note, or
otherwise, if there shall have occurred and be continuing, and the Corporation
and the Holder shall have received notice from the holder or holders of, a
default with respect to any Senior Indebtedness (i) permitting the acceleration
thereof and such default is the subject of a judicial proceeding, or (ii) in an
aggregate principal amount of not less than One Million Dollars ($1,000,000)
entitling such holder or holders of, a default with respect to any Senior
Indebtedness (i) permitting the acceleration thereof and such default is the
subject of a judicial proceeding, or (ii) in an aggregate principal amount of
not less than One Million Dollars ($1,000,000) entitling such holder or holders
to compel the acceleration thereof (provided, however, that in the case of
Senior Indebtedness issued pursuant to an indenture, such notice may be validly
given only by the trustee under such indenture), unless and until such default
or Event of Default shall have been cured or waived or shall have ceased to
exist or such notice is withdrawn or found by a court of competent jurisdiction
to be invalid.

                  (b) Upon any payment by the Corporation or distribution of
assets of the Corporation of any kind or character, whether in cash, property,
or securities, to creditors of the Corporation under any dissolution or winding
up or liquidation or reorganization of the Corporation, whether voluntary or
involuntary, or in bankruptcy, insolvency, receivership, or other similar



                                       14

   15



proceedings, all amounts due or to become due upon all Senior Indebtedness shall
first be paid in full in money or money's worth, or payment thereof provided
for, before any payment is made on account of the principal of or interest on
this Note and upon such dissolution or winding up or liquidation or
reorganization, any payment by the Corporation, or distribution of assets of the
Corporation of any kind or character, whether in cash, property, or securities,
to which the Holder would be entitled except for the provisions hereof, shall be
paid by the Corporation or by any receiver, trustee in bankruptcy, liquidating
trustee, agent, or other person making such payment or distribution directly to
the holders of Senior Indebtedness or their representative or representatives,
or to the trustee or trustees under any indenture pursuant to which any
instruments evidencing any Senior Indebtedness may have been issued, as their
respective interests may appear, to the extent necessary to pay all Senior
Indebtedness in full in money or money's worth, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness,
before any payment or distribution is made to the Holder.

                  (c) The foregoing notwithstanding, in the event that any
payment of or distribution of assets of the Corporation of any kind or
character, whether in cash, property or securities, prohibited by the foregoing,
shall be received by the Holder before all Senior Indebtedness is paid in full
in money or money's worth, or provision is made for such payment, then and in
such event such payment or distribution shall be paid over or delivered to the
holders of Senior Indebtedness or their representative or representatives, or to
the trustee or trustees under any indenture pursuant to which any instruments
evidencing any Senior Indebtedness may have been issued, as their respective
interests may appear, for application to the payment of all Senior Indebtedness
remaining unpaid to the extent necessary to pay all Senior Indebtedness in full
in money or money's worth, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Indebtedness may have been
issued, as their respective interests may appear, for application to the payment
of all Senior Indebtedness remaining unpaid to the extent necessary to pay all
Senior Indebtedness in full in money or money's worth, after giving effect to
any concurrent payment or distribution to or for the holders of such Senior
Indebtedness (but subject to the power of a court of competent jurisdiction to
make other equitable provision, which shall have been determined by such court
to give effect to the rights conferred herein upon the Senior Indebtedness and
the holders thereof with respect to this Note or the Holder hereof by a lawful
plan or reorganization or readjustment under applicable bankruptcy law).

                  (d) The holders of Senior Indebtedness may, at any time and
from time to time, without the consent of or notice to the Holder, without
incurring responsibility to the Holder and without impairing or releasing the
obligations of the Holder to the holders of Senior Indebtedness: (i) change the
manner, place, or terms of payment or change or extend the time of payment of,
or renew or alter Senior Indebtedness, or otherwise amend, in any manner, Senior
Indebtedness is outstanding; provided, however, that the average weighted
maturity of such Senior Indebtedness shall not be decreased without the consent
of the Holder; (ii) sell, exchange, release, or otherwise deal with any property
pledged, mortgaged, or otherwise securing Senior Indebtedness; (iii) release any
person liable in any manner for the collection of Senior Indebtedness; and (iv)
exercise or refrain from exercising any rights against the Corporation and any
other person.

   16



                  (e) Subject to the payment in full of all amounts then due
(whether by acceleration of the maturity thereof or otherwise) on account of the
principal of, premium, if any, and interest on all Senior Indebtedness at the
time outstanding, the Holder shall be subrogated to the rights of the holders of
Senior Indebtedness to receive payments or distributions of cash, property, or
securities of the Corporation applicable to the Senior Indebtedness until the
principal of and interest on this Note shall be paid in full; and, for the
purposes of such subrogation, no payments or distributions by the Corporation to
the holders of Senior Indebtedness of any cash, property, or securities to which
the Holder would be entitled except for the provisions hereof, and no payments
over pursuant to the provisions hereof to the holders of Senior Indebtedness by
the Holder, shall, as between the Corporation, its creditors other than holders
of Senior Indebtedness, and the Holder, be deemed to be a payment by the
Corporation to or on account of the Senior Indebtedness.

                  (f) It is understood that the foregoing provisions of this
Note are and are intended solely for the purpose of defining the relative rights
of the Holder on the one hand and the holders of Senior Indebtedness on the
other hand. Nothing contained in this Note is intended to or shall impair, as
among the Corporation, its creditors other than the holders of Senior
Indebtedness, and the Holder, the obligation of the Corporation, which is
absolute and unconditional, to pay to the Holder the principal of and interest
on this Note as and when the same shall become due and payable in accordance
with its terms, or is intended to or shall affect the relative rights of the
Holder and creditors of the Corporation other than the holders of Senior
Indebtedness, nor shall anything herein prevent the Holder from exercising all
remedies otherwise permitted by applicable law upon default under this Note or
the Note Purchase Agreement.

                  (g) Upon any payment or distribution of assets of the
Corporation referred to herein, the Holder shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which such
dissolution, winding up, liquidation, or reorganization proceedings are pending,
or certificate of the receiver, trustee in bankruptcy, liquidating trustee,
agent, or other person making such payment or distribution, delivered to the
Holder, for the purpose of ascertaining the persons entitled to participate in
such distribution, the holders of Senior Indebtedness and other indebtedness of
the Corporation, the amount thereof or payable thereon, the amount or amounts
paid or distributed thereon, and all other facts pertinent thereto.

                  (h) The Corporation shall give prompt written notice to the
Holder of any fact known to the Corporation that would prohibit the making of
any payment of moneys to or by the Corporation in respect of this Note.

                  SECTION 9. ACCELERATION. This Note and the indebtedness
evidenced hereby is subject to acceleration under the terms and conditions set
forth in the Note Purchase Agreement.

                  SECTION 10. MISCELLANEOUS. (a) Any notice required by the
provisions of this Note to be given to the Holder or the Corporation shall be
given and deemed received or delivered in accordance with the provisions of
Section 10.4 of the Note Purchase Agreement.



                                       16

   17



                  (b) In the event of prepayment or conversion of this Note in
part only, a new note or notes for the unpaid or unconverted portion hereof will
be issued in the name or names requested by the Holder upon the cancellation
hereof.

                  (c) The transfer of this Note is registrable on the books of
the Corporation upon surrender of this Note for registration of transfer at the
offices of the Corporation in Nashville, Tennessee, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Corporation duly executed by, the Holder or its attorney duly authorized in
writing, and thereupon one or more new notes of authorized denominations and for
the same aggregate principal amount, will be issued to the designated transferee
or transferees. New notes are issuable only in registered form without coupons
in denominations of One Thousand Dollars ($1,000) and any integral multiple
thereof. This Note is exchangeable for a like aggregate principal amount of
notes of a different authorized denomination, as requested by the Holder. No
service charge shall be made of any such registration of transfer or exchange,
