$2,765,652.76                                          Charlotte, North Carolina
                                                                  April 12, 2002

     FOR VALUE RECEIVED, the undersigned (the "Company") promises to pay to the
order of Centra Benefit Services, Inc. (the "Holder") the principal sum of TWO
MILLION SEVEN HUNDRED SIXTY FIVE THOUSAND SIX HUNDRED FIFTY-TWO DOLLARS AND
SEVENTY-SIX CENTS ($2,765,652.76). All sums are payable by personal delivery or
by mail at 7803 Glenroy Road, Suite 300, Bloomington, Minnesota 55439, Attn.
Michael T. Davies, or at such other address as the Holder may designate in
writing.

     This Note amends and restates, without interruption or novation, the
indebtedness evidenced by that certain Convertible Promissory Note dated June
16, 1998 and referred to in the Subscription and Contribution Agreement (the
"Subscription Agreement") dated June 16, 1998 by and among HealthPlan Services,
Inc. ("HPS") and CENTRA Benefit Services, Inc. (this Note, together with the
various other notes specified in the Subscription Agreement and listed on
Schedule 1 hereto, are herein referred to as the "Original Notes"). This Note is
also one of the Notes referenced in and entitled to the benefits of that certain
Letter Agreement between the undersigned, NJK Holding Corporation and Holder
dated as of April 11, 2002. Upon the execution and delivery of this Note the
Original Notes will be returned to the undersigned for cancellation and shall
have no further force or validity.

     1.  Interest. The principal obligation evidenced by this Note shall bear
interest at the rate of twelve percent (12%) per annum. Interest shall be due
and payable as described below.

     2.  Principal and Interest Payments. The principal balance of this Note and
accrued interest shall be paid as follows:

         (a) Compound interest shall accrue monthly, and shall be paid on a
     quarterly basis, commencing on June 30, 2002, in in-kind shares of the
     Company's Common Stock, $.01 par value per share (the "Common Stock"), the
     number of which will be determined by dividing the amount of interest
     accrued for the quarter by the average trading price of the Common Stock on
     the New York Stock Exchange during the last ten trading days of the quarter
     (the "PIK Shares"). The PIK Shares representing each quarter's interest
     payment will be delivered to the Holder as soon as practicable not later
     than the fifth business day of the succeeding quarter. Notwithstanding the
     foregoing, the Holder may elect, by giving written notice to the Company at
     least one business day prior to the end of each quarter, to defer receipt
     of interest payments for the completed quarter until (i) a date not later
     than 90 days after completion of the Company's fiscal year, at which time
     the Company will pay accrued interest in cash to the extent permitted by
     the Senior Credit Facility as hereafter defined from funds available from
     Available Excess Cash Flow, as defined below, with any remaining balance to
     be paid in PIK Shares, or (ii) Maturity of this Note, as defined below, at
     which point such interest will be paid in cash, together with all principal
     hereunder.

                                      -2-

<PAGE>

          "Available Excess Cash Flow" means, for each completed fiscal year of
          the Company, the funds available from Excess Cash Flow, as that term
          is defined in that certain Third Amended and Restated Credit Agreement
          dated on or about April 5, 2002 by and among PlanVista Corporation
          (f/k/a HealthPlan Services Corporation) and PlanVista Solutions, Inc.
          (f/k/a National Preferred Provider Network, Inc.), as Borrowers, the
          lenders thereunder (the "Senior Lenders") and Wachovia Bank, National
          Association (f/k/a First Union National Bank), as Administrative Agent
          for the Senior Lenders (in such capacity and in its capacity as agent
          for the holders of the Series C Shares (as defined below) (hereafter
          the "Administrative Agent") as in effect on the date hereof (as
          amended, restated, supplemented, replaced, refinanced, extended or
          otherwise modified from time to time, the "Senior Credit Facility")),
          after making any mandatory prepayments to the Senior Lenders under the
          Senior Credit Facility from Excess Cash Flow.

               (b) Unless earlier converted pursuant to the terms of Paragraph 3
          below, the Company shall pay all outstanding principal hereunder,
          together with all then accrued and unpaid interest, on the 1st day of
          December, 2004 (the "Maturity Date").

     3.   Conversion Rights. At any time following the close of business of
April 12, 2002 (the "Effective Date") the Holder shall have the right, at its
option, at any time and from time to time prior to the Maturity Date, to convert
in whole or in part provided that no conversion is for an amount less than
twenty-five percent (25%) of the principal amount of this Note, subject to the
terms and provisions contained herein, any portion of the original principal
amount of this Note (to the extent such amount has not been reduced by a partial
prepayment pursuant to Paragraph 8 hereof) into shares of the Common Stock, at a
conversion price equal to the lesser of (i) the average trading price of the
Common Stock on the New York Stock Exchange for the ten day period immediately
preceding the date on which the Holder provides the Company notice of its desire
to convert any portion of this Note or (ii) Twenty-Five cents ($0.25) plus the
average trading price of the Common Stock on the New York Stock Exchange for the
ten day period immediately preceding the date of this Note (the "Conversion
Price"). Such conversion shall be effective upon surrender of this Note to the
Company at its principal office at any time during usual business hours,
accompanied, if so required by Company, by a written instrument or instruments
of transfer in form satisfactory to Company duly executed by the Holder or its
attorney duly authorized in writing. In the event of a partial conversion, the
Company shall issue a new note, under the same terms and conditions as set forth
herein, for the remaining balance of the Note. Notwithstanding anything stated
herein, in the event that the Senior Lenders, or any of them, convert any of the
Company's Series C Convertible Preferred Stock, par value $0.01 (the "Series C.
Shares") into shares of the Company's Common Stock at any time after October 3,
2003, the conversion price hereunder will be the lesser of (i) the Conversion
Price or (ii) the price at which the Senior Lenders, or any of them, converted
such Series C Shares.

     4.   Issuance of Common Stock Upon Conversion. Within 30 business days
after the surrender of this Note, or part thereof, for conversion, the Company
shall issue and deliver or cause to be issued and delivered to or upon the
written order of the Holder certificates representing the number of fully paid
and nonassessable shares of Common Stock into which this Note, or part

                                      -3-

<PAGE>

thereof, is converted. Such conversion shall be deemed to have been made at the
close of business on the date that this Note shall have been surrendered for
conversion in whole or in part so that the rights of the Holder with respect to
the principal amount of this Note shall cease at such time, and the Holder
entitled to receive the shares of Common Stock upon conversion of this Note
shall be treated for all purposes as having become the record holder of such
shares of Common Stock at such time and such conversion shall be at the
Conversion Price.

     5.   Conversion Price Adjustments.

          (a) Adjustment for Stock Splits and Subdivisions. In the event the
     Company should at any time or from time to time after the Effective Date)
     fix a record date for the effectuation of a split or subdivision of the
     outstanding shares of Common Stock or the determination of holders of
     Common Stock entitled to receive a dividend or other distribution payable
     in additional shares of Common Stock or other securities or rights
     convertible into, or entitling the holders thereof to receive directly or
     indirectly, additional shares of Common Stock without payment of any
     consideration by such holder for the additional shares of Common Stock,
     then, as of such record date, the Conversion Price shall be appropriately
     decreased so that the number of shares of Common Stock issuable upon
     conversion of this Note shall be increased in proportion to such increase
     of outstanding shares.

          (b) Adjustments for Reverse Stock Splits. If the number of shares of
     Common Stock outstanding at any time after the Effective Date is decreased
     by a combination of the outstanding shares of Common Stock then, following
     the record date of such combination, the Conversion Price for this Note
     shall be appropriately increased so that the number of shares of Common
     Stock issuable on conversion thereof shall be decreased in proportion to
     such decrease in outstanding shares.

          (c) Adjustments for Recapitalizations. In the event that the Company
     shall be recapitalized, consolidated with or merged into any other
     corporation, or shall sell or convey to any other corporation all or
     substantially all of its property as an entirety, provision shall be made
     as part of the terms of such recapitalization, consolidation, merger, sale
     or conveyance so that the Holder of this Note may thereafter receive, in
     lieu of the Common Stock otherwise issuable upon conversion, the same kind
     and amount of securities or assets as may be distributable upon such
     recapitalization, consolidation, merger, sale or conveyance, with respect
     to the Common Stock.

          (d) Adjustments. The adjustments referred to in this Paragraph 5 shall
     be made successively if more than one event listed herein shall occur.

     6.   Compliance with Securities Laws. The Holder acknowledges that this
Note and the shares of Common Stock into which it is convertible have not been
and will not be registered under the Securities Act of 1933, as amended (the
"1933 Act") and therefore may not be resold without compliance with the 1933
Act. The Holder agrees that this Note is being acquired solely

                                      -4-

<PAGE>

for its own account, for investment purposes only, and with no present intention
of distributing, selling or otherwise disposing of it in connection with a
distribution. The Holder covenants, warrants and represents that this Note and
the shares of Common Stock into which it is convertible will not be offered,
sold, assigned, pledged, hypothecated, transferred or otherwise disposed of
except (i) pursuant to an effective Registration Statement under the 1933 Act,
or (ii) after full compliance with all of the applicable provisions of the 1933
Act and all other applicable rules and regulations of the SEC and after the
issuance by counsel to the Company of an opinion that such offer, sale, or other
transaction is exempt from the registration requirements of the 1933 Act. The
Holder further covenants, warrants and represents that, during the one-year
period following the Effective Date, the undersigned will not engage in put,
call, short-sale, straddle or similar transactions intended to reduce the
Holder's risk of owning this Note or the shares of Common Stock into which it is
convertible. Upon the conversion of this Note in whole or in part, certificates
representing the shares of Common Stock shall bear the following legend:

     The shares represented by this certificate were not issued in a
     transaction registered under the Securities Act of 1933, as
     amended (the "Securities Act"), or any applicable state
     securities laws. The shares represented hereby have been acquired
     for investment only and may not be sold or transferred unless
     such sale or transfer is covered by an effective Registration
     Statement under the Securities Act and applicable state
     securities laws or, in the opinion of counsel to the issuer, is
     exempt from the registration requirements of the Securities Act
     and such laws.

     7. Payment of Interest on Conversion. The Company shall pay all interest on
this Note accrued to the date of surrender for a conversion pursuant to the
terms of Paragraph 3 (the "Surrender Date") except that, in the event that the
Company shall have declared prior to the Surrender Date a cash dividend payable
on its shares of Common Stock to holders of record of such Common Stock on a
date subsequent to the Surrender Date, such payment of interest shall be
adjusted downward to an amount (not less than zero) determined by subtracting
from the aggregate amount thereof an amount equal to the aggregate dividends to
be paid as of such record date on the shares of Common Stock issuable upon
conversion of this Note.

     8. Prepayment. Subject to the subordination provisions of paragraph 11,
this Note may be prepaid in whole or in part, at any time without premium or
penalty at the option of the Company at a prepayment price equal to 100% of the
principal amount to be prepaid plus accrued interest to the prepayment date. In
order to exercise its right to prepayment hereunder, the Company shall send
written notice to the Holder of the Company's intention to exercise its
prepayment rights hereunder, which notice shall be provided not less than
sixteen (16) calendar days prior to the stated date of prepayment. In the case
of partial prepayment, the amount and other details thereof shall be noted.
Following the date of notice of prepayment, or partial prepayment, as the case
may be, the Holder's conversion rights provided in Paragraph 3 hereof shall be
accelerated and the Holder shall have a period of fifteen (15) calendar days to
exercise such conversion rights. After the expiration of such fifteen (15) day
period, unless the Company shall have failed to tender

                                 -5-

<PAGE>

to the Holder the amount to be prepaid and accrued interest under this Note, the
Holder shall have no further rights of conversion.

     9.  Default. If any portion of the principal or interest of this Note is
not paid when due, and the Company fails to cure the same within thirty (30)
days after such event, then default shall be deemed to have occurred on the
termination of such thirty (30) day period.

     10. Right of Acceleration. Upon the happening of any of the following
events, the entire unpaid principal balance and accrued interest of this Note
shall, at the option of the Holder, become immediately due and payable, and may
be collected forthwith without notice to the Company, regardless of the
stipulated date of maturity:

         (a) Upon a default in payment under this Note; or

         (b) If the undersigned becomes insolvent or bankrupt or unable to pay
     its obligations as they become due, or the undersigned makes an assignment
     for the benefit of its creditors, or the undersigned files a petition under
     the bankruptcy laws of the United States, or the undersigned suffers to be
     filed a petition under the bankruptcy laws of the United States which is
     (i) consented to by the undersigned or (ii) not dismissed within sixty (60)
     days thereof, or a receiver is appointed for the property or business of
     the undersigned.

         11. Subordination. The Company agrees, and the Holder by accepting this
Note agrees, notwithstanding anything in this Note to the contrary, to the
subordination of this Note as follows:

             (a) Any and all obligations and liabilities of the Company to
         Holder under this Note, including, without limitation, payment of
         principal and interest (other than, so long as no Proceeding has been
         commenced, payment of interest in PIK Shares or cash interest paid from
         Excess Cash Flow as specifically permitted under the terms of this
         Note), whether direct or indirect, absolute or contingent, joint or
         several, secured or unsecured, due or to become due, now existing or
         later arising and whatever the amount and however evidenced (the
         "Subordinated Indebtedness") are subordinated in right and time of
         payment to any and all obligations and liabilities of the Company to
         (i) the Administrative Agent and the Senior Lenders under or in
         connection with the Company's Senior Credit Facility and any other loan
         document contemplated thereby or related thereto, including, without
         limitation principal and interest payments, whether direct or indirect,
         absolute or contingent, joint or several, secured or unsecured, due or
         to become due, now existing or later arising and however evidenced, and
         whether arising prior to or after the commencement of any proceeding
         under Title 11 of the United States Code or is an allowed claim in any
         such proceeding, together with all other sums due thereon and all costs
         of collecting the same (including, without limitation, reasonable
         attorney fees) for which the Company is liable and any other
         obligations of the Company or its subsidiaries to the Senior Lenders
         and (ii) the Administrative Agent and holders of the Company's shares
         of Series C Preferred Stock, $.01 par value per share (the "Series C
         Shares"), including, without limitation,

                                      -6-

<PAGE>

     payment of the full Liquidation Preference of the Series C Shares upon
     Liquidation and payment of the Redemption Price at redemption (as each such
     term is defined in the Certificate of Designation of Series and
     Determination of Rights and Preferences of Series C Convertible Preferred
     Stock relating to the Series C Preferred Stock, as such provisions may be
     amended, restated, supplemented or otherwise modified from time to time, a
     copy of which has been delivered to Holder), as applicable, whether direct
     or indirect, absolute or contingent, joint or several, secured or
     unsecured, due or to become due, now existing or later arising and however
     evidenced and whether arising prior to or after the commencement of any
     proceeding under Title 11 of the United States Code or is an allowed claim
     in any such proceeding, together with all other sums due thereon and all
     costs of collecting the same (collectively, the "Senior Obligations").

          (b) Until the indefeasible payment in full in cash of the Senior
     Obligations, Holder will not ask for, demand, sue for, take or receive (by
     way of voluntary or mandatory payment, acceleration, set-off or
     counterclaim, foreclosure or other realization on security, dividends in
     bankruptcy or otherwise), or offer to make any discharge or release of, any
     of the Subordinated Indebtedness, and Holder waives any such rights with
     respect to the Subordinated Indebtedness, nor shall Holder exercise any
     rights of subrogation or other similar rights with respect to the Senior
     Obligations.

          (c) In the event of any Proceeding involving the Company: (i) all
     Senior Obligations first shall be indefeasibly paid in full in cash before
     any payment of or with respect to the Subordinated Indebtedness shall be
     made; (ii) any payment or distribution, whether in cash, property or
     securities which, but for the terms hereof, otherwise would be payable or
     deliverable in respect of the Subordinated Indebtedness, shall be paid or
     delivered directly to the Administrative Agent until all Senior Obligations
     are indefeasibly paid in full in cash, and Holder irrevocably authorizes,
     empowers and directs all receivers, trustees, liquidators, custodians,
     conservator and others having authority in the premises to effect all such
     payments and distributions, and Holder also irrevocably authorizes,
     empowers and directs the Administrative Agent to demand, sue for, collect
     and receive every such payment or distribution; and (iii) Holder agrees not
     to initiate or prosecute or encourage any other person to initiate or
     prosecute any claim, action or other proceeding challenging the
     enforceability of the Senior Obligations. For purposes hereof, the term
     "Proceeding" shall mean any voluntary or involuntary insolvency,
     bankruptcy, receivership, custodianship, liquidation, dissolution,
     reorganization, assignment for the benefit of creditors, appointment of a
     custodian, receiver, trustee or other officer with similar powers or any
     other proceeding for the reorganization, liquidation, dissolution or other
     winding upon the Company.

(d)  Should any payment, distribution of property or securities (other than, so
     long as no Proceedings has commenced, PIK Shares in respect of accrued
     interest or cash interest paid from Excess Cash Flow as specifically
     permitted under the terms of this Note) or proceeds be received by Holder
     upon or with respect to the Subordinated Indebtedness prior to the
     satisfaction in full of the Senior Obligations, Holder shall immediately
     deliver same to the

                                      -7-

<PAGE>

     Administrative Agent in the form received (except for endorsement or
     assignment by Holder where required by the Administrative Agent), for
     application on the Senior Obligations (whether or not then due and in such
     order of maturity as the Administrative Agent elects) and, until so
     delivered, the same shall be held in trust by Holder as the property of the
     Administrative Agent, Senior Lender, and the holders of the Series C
     Shares. In the event of the failure of Holder to make any endorsement or
     assignment, the Administrative Agent is irrevocably authorized and
     appointed as attorney-in-fact for Holder to make the same.

             (e) Notwithstanding any prior revocation, termination, surrender,
     or discharge of this Note in whole or in part, or of the provisions of this
     Paragraph 11, the effectiveness of the subordination provisions of this
     Paragraph 11 (the "Subordination Provisions") shall automatically continue
     or be reinstated in the event that any payment received or credit given by
     the Administrative Agent, any Senior Lender or any holder of Series C
     Shares in respect of the Senior Obligations are returned, disgorged, or
     rescinded under any applicable state or federal law, including, without
     limitation, laws pertaining to bankruptcy or insolvency, in which case the
     Subordination Provisions shall be enforceable against Holder as if the
     returned, disgorged, or rescinded payment or credit had not been received
     or given by the Administrative Agent, any Senior Lender or any holder of
     Series C Shares relied upon this payment or credit or changed its position
     as a consequence of it.

             (f) This Note constitutes a continuing agreement of subordination,
     even though at times the Company may not be indebted to or obligated to
     make payments to the Administrative Agent, Senior Lenders or holders of the
     Series C Shares. This Note shall bind and be for the benefit of Holder, the
     Administrative Agent, Senior Lenders and the holders of the Series C Shares
     and their respective successors and assigns. This Note may not be
     accelerated and, except for interest payments expressly permitted in this
     Paragraph 11, may not be prepaid.

             (g) Holder hereby agrees that it will not amend, modify or
     otherwise alter (or suffer to be amended, modified or altered), any of the
     terms and conditions of this Note without prior written notice to and the
     approval of the Administrative Agent.

             (h) Nothing stated herein is intended, so long as no Proceeding has
     commenced, to: (a) subordinate, prevent or limit the Company from paying
     PIK Shares to Holder as interest or limit Holder from accepting such PIK
     Shares for its own benefit and account, or (b) subordinate, prevent or
     limit the Company from making cash interest payments, to the extent
     permitted by the Credit Agreement, from Excess Cash Flow as provided herein
     or prevent Holder from accepting such cash payment for its own benefit and
     account. Notwithstanding anything in this Note to the contrary, from and
     after June 12, 2005, so long as no Proceeding has commenced prior to such
     date, the subordination provisions of this Paragraph 11 shall no longer
     apply to the Senior Obligations in respect of

                                      -8-

<PAGE>

         the Series C Shares but for the avoidance of doubt shall remain in
         effect in all respects with respect to all other Senior Obligations.

         12. Waiver. Presentment for payment, notice of dishonor, protest and
notice of protest are hereby waived.

         13. Choice of Law; Venue. This Note shall be governed by, and construed
and enforced in accordance with, the laws of the State of Florida. The Company
consents and agrees that Hillsborough County, Florida, shall be the proper,
exclusive, and convenient venue for any legal proceeding in federal or state
court arising under this Note, and waives any defense, whether asserted by
motion or by pleading, that Hillsborough County, Florida, is an improper or
inconvenient venue.

         14. Binding Effect. This Note shall be binding upon the Company and its
successors and assigns and shall inure to the benefit of the Holder.

                                      -9-

         IN WITNESS WHEREOF, the Company has executed this Note by and through
its duly authorized officer effective the date written above.
