Company's Class A Common Stock, $0.001 par value per share (the "Shares"), at
the price equal to the Exercise Price (as defined in Section 1 hereof) (subject

Agreement"; and together with all related promissory notes, mortgages,
guaranties, agreements, documents and instruments from time to time entered into
by Company and any other person or obligor pursuant thereto, the Credit
Documents")

      This Warrant amends and restates in its entirety that certain Warrant for
up to two hundred eighteen thousand, one hundred and eight-two (218,182) fully
paid and non-assessable shares of the Company's Class A Common Stock, $0.001 par

            (B) or on Common Stock so excluded; or

            (D) shares issued under an employee stock purchase plan or pursuant
            to options exercisable for shares of Common Stock (such number
            subject to equitable adjustment in the event of any stock dividend,
            stock split, combination, reorganization, recapitalization,
            reclassification or other similar event), issued after the date of
            this Warrant to directors, officers, employees or consultants of the
            Company and any Subsidiary pursuant to any qualified or
            non-qualified stock option plan or other equity incentive plan
            approved by the Board of Directors of the Company, equal to the
            first 30% of the outstanding stock of the Company, calculated on a
            post-Original Issue Date, fully-diluted basis.

            "Common Stock" shall mean the Class A Common Stock of the Company,
            $0.001 par value per share.

            "Convertible Securities" shall mean any evidences of indebtedness,

            or exchangeable for Common Stock.

            "Exercise Price" shall mean $0.60 per share.

            originally issued.

      2. Purchase Rights. The purchase rights represented by this Warrant are
exercisable by the Holder in whole or in part (and not as to a fractional
share), at any time and from time to time commencing on the date hereof and
ending at 5:00 p.m. on the date (the "Expiration Date") eighteen (18) months
after the indefeasible payment in full in cash or cash equivalents of the Credit
Obligations.

      3. Exercise of Warrant; Net Issue Exercise.

      3.1 Exercise of Warrant. Subject to Section 2 above, the purchase rights
represented by this Warrant may be exercised, in whole or in part and from time
to time, by the surrender of this Warrant and the duly executed Notice of
Exercise (the form of which is attached as Exhibit A) at the principal office of
the Company and by the payment to the Company, by check, of an amount equal to
the then applicable Exercise Price per share multiplied by the number of Shares
then being purchased. Upon exercise, the Holder shall be entitled to receive,
within a reasonable time, a certificate or certificates, issued in the Holder's
name or in such name or names as the Holder may direct, for the number of Shares
so purchased. The Shares so purchased shall be deemed to be issued as of the
close of business on the date on which this Warrant shall have been exercised.

      3.2. Net Issue Exercise.

            (a) In lieu of exercising this Warrant as set forth in Section 3.1,
      the Holder may elect to receive Shares equal to the value of this Warrant
      (or the portion thereof being cancelled) by surrender of this Warrant at
      the principal office of the Company together with notice of such election
      in which event the Company shall issue to the Holder a number of Shares
      computed using the following formula:

                                  X = Y (A - B)
                                  ------------
                                        A

                                       2
<PAGE>
Where X = the number of Shares to be issued to the Holder;

      Y =      the number of Shares purchasable under this Warrant, or if only a
               portion of this Warrant is being cancelled, the gross number of
               Shares covered by the portion of this Warrant being cancelled;

      A =      the fair market value of one Share, as determined by the Board of
               Directors of the Company pursuant to paragraph (b) below, as at
               the time the net issue election is made pursuant to this Section
               (the "Determination Date"); and

      B =      the Exercise Price (as adjusted to the date of such
               calculations).

Such Shares shall be issued as soon as practicable after the Determination Date.

            (b) For purposes of this Section, fair market value of a Share shall
      be determined as follows:

                        (A) If the Company's Common Stock is not publicly traded
                  at the Determination Date, the fair market value of a Share
                  shall be a value reasonably determined by the Company's Board
                  of Directors. In the event that the Holder disagrees with the
                  Board of Directors' determination of fair market value, then
                  the fair market value shall be determined by an appraiser
                  selected by the Holder (the "Holder's Appraiser") and whose
                  appraisal (the "Holder's Appraisal") shall be furnished to the
                  Company within 20 days after the Board of Directors'
                  determination of fair value, and if the Company does not
                  object to such determination within 15 days after receipt of
                  the Holder's appraisal, then the fair market value determined
                  by the Holder's Appraiser shall be the fair market value of a
                  Share. In the event that the Company objects to such
                  determination then the Company shall select an appraiser (the
                  "Company's Appraiser") who shall review the determination of
                  the Holder's Appraiser and issue a report thereon (the
                  "Company's Appraisal") within 30 days after the delivery of
                  the Holder's Appraisal to the Company and within 10 days after
                  the issuance of such report to the Holder's Appraiser, the
                  Holder's Appraiser and the Company's Appraiser shall meet to
                  negotiate in good faith to reach agreement on the fair market
                  value of a Share, and such agreed value shall be the fair
                  market value of a Share. In the event that the Company's
                  Appraiser and the Holder's Appraiser are unable to reach
                  agreement then such Appraisers shall select an appraiser (the
                  "Third Appraiser") within 5 days after the meeting between the
                  Holder's Appraiser and the Company's Appraiser, and the
                  average of two appraisals, consisting of the appraisal made by
                  the Third Appraiser and the appraisal of the Holder's
                  Appraiser and Company's Appraiser (whichever is closest to
                  that of the Third Appraiser), shall be conclusive and binding
                  on the Company and the Holder. The Company and the Holder
                  shall each pay one half (1/2) of the fees and expenses of each
                  of the Company's Appraiser, the Holder's Appraiser and the
                  Third Appraiser.

                        (B) if the Company's Common Stock is publicly traded on
                  the Determination Date, the fair market value of a Share shall
                  be equal to (1) the average of the closing prices quoted on
                  the Nasdaq Stock Exchange, Inc., if applicable, or the average
                  of the last bid and asked prices of the Common Stock quoted in
                  the Nasdaq OTC Bulletin Board or the over-the-counter-market,
                  or (2) if the Common Stock is then traded on a national
                  securities exchange, the average of the high and low closing
                  prices of the Common Stock listed on the principal national
                  securities exchange on which the Common Stock is so traded, in
                  each case for the twenty (20) trading days preceding the
                  Determination Date.

                                       3

      4. Shares to be Issued; Reservation of Shares. The Company covenants that
the Shares that may be issued upon the exercise of the purchase rights
represented by this Warrant will, upon issuance, be fully paid and
non-assessable, and free from all liens and charges with respect to the issue
thereof. During the period within which the purchase rights represented by the
Warrant may be exercised, the Company will at all times have authorized and
reserved, for the purpose of issuance upon exercise of the purchase rights
represented by this Warrant, a sufficient number of shares of its Common Stock
to provide for the exercise of the right represented by this Warrant.

      5. No Fractional Shares. No fractional shares shall be issued upon the
exercise of this Warrant. In lieu thereof, a cash payment shall be made equal to
such fraction multiplied by the fair market value of such shares of Common
Stock, as determined pursuant to Section 3.2(b) above.

      6. Adjustment for Merger, Consolidation or Sale of Assets. In the event
that at any time or from time to time after the Original Issue Date, the Company
shall merge or consolidate with or into another entity or sell all or
substantially all of its assets, the Holder hereof shall thereafter have the
right to receive the kind and amount of shares of stock, other securities,
property or cash deliverable or payable to the holders of the Common Stock of
the Company that the Holder hereof upon exercise of this Warrant would have been
entitled to had the Holder hereof exercised the remaining portion of this
Warrant into shares of Common Stock immediately prior thereto.

      7. Adjustment of Exercise Price and Number of Shares.

            (a) Adjustment of Exercise Price and Number of Shares. The Exercise
      Price and number of shares of Common Stock issuable upon the exercise of
      the Warrant shall be adjusted as set forth in this Section 7 with the
      intent that the rights of the Holder to exercise shall not be impaired.

            (b) Adjustment for Combination, Consolidation, Stock Dividend or
      Subdivision of Common Stock. If the outstanding shares of Common Stock
      shall be subdivided into a greater number of shares or a dividend in
      Common Stock shall be paid in respect of Common Stock, the Exercise Price
      in effect immediately prior to such subdivision or at the record date of
      such dividend shall simultaneously with the effectiveness of such
      subdivision or immediately after the record date of such dividend be
      proportionately reduced. If outstanding shares of Common Stock shall be
      combined or consolidated into a smaller number of shares, the Exercise
      Price in effect immediately prior to such combination or consolidation
      shall, simultaneously with the effectiveness of such combination or
      consolidation, be proportionately increased. When any adjustment is
      required to be made in the Exercise Price, the number of shares of Common
      Stock purchasable upon the exercise of this Warrant shall be changed to
      the number determined by dividing (i) an amount equal to the number of
      shares issuable upon the exercise of this Warrant immediately prior to
      such adjustment, multiplied by the Exercise Price in effect immediately
      prior to such adjustment, by (ii) the Exercise Price in effect immediately
      after such adjustment.

            (c) Issue of Options and Convertible Securities Deemed Issue of
      Additional Shares of Common Stock. If the Company at any time or from time
      to time after the Original Issue Date shall issue any Options or
      Convertible Securities or shall fix a record date for the determination of
      holders of any class of securities entitled to receive any such Options or
      Convertible Securities, then the maximum number of shares of Common Stock
      (as set forth in the instrument relating thereto, without regard to any
      provision contained therein for a subsequent adjustment of such number)
      issuable upon the exercise of such Options or, in the case of Convertible
      Securities or Options therefor, the conversion or exchange of such
      Convertible Securities, shall be deemed to be Additional Shares of Common
      Stock issued as of the time of such issue or, in case such a record date
      shall have been fixed, as of the close of business on such record date,
      provided that Additional Shares of Common Stock shall not be deemed to
      have been issued unless the consideration per share (determined pursuant
      to paragraph (e) below) of such Additional Shares of Common Stock would be
      less than the Exercise Price in effect on the date of and immediately

                                       4
<PAGE>
      prior to such issue, or such record date, as the case may be, and provided
      further in any such case in which Additional Shares of Common Stock are
      deemed to be issued:

                  (i) No further adjustment in the Exercise Price shall be made
            upon the subsequent issue of Convertible Securities or shares of
            Common Stock upon the exercise of such Options or conversion or
            exchange of such Convertible Securities;

                  (ii) If such Options or Convertible Securities by their terms
            provide, with the passage of time or otherwise, for any increase in
            the consideration payable to the Company, or decrease in the number
            of shares of Common Stock issuable, upon the exercise, conversion or
            exchange thereof, the Exercise Price computed upon the original
            issue thereof (or upon the occurrence of a record date with respect
            thereto), and any subsequent adjustments based thereon, shall, upon
            any such increase or decrease becoming effective, be recomputed to
            reflect such increase or decrease insofar as it affects such Options
            or the rights of conversion or exchange under such Convertible
            Securities;

                  (iii) No readjustment pursuant to clause (ii) above shall have
            the effect of increasing the Exercise Price to an amount which
            exceeds the lower of (A) the Exercise Price immediately prior to the
            adjustment affected upon the original issue of Options or
            Convertible Securities (or upon the occurrence of a record date with
            respect thereto) pursuant to the provisions hereof, or (B) the
            Exercise Price that would have resulted from any issuance of
            Additional Shares of Common Stock between the original adjustment
            date and such readjustment date;

                  (iv) Upon the expiration or termination of any unexercised
            Option, the Exercise Price shall be readjusted to the Exercise Price
            which would have been in effect at the time of such expiration or
            termination had such Option never been issued (but including the
            recalculation of any intervening adjustments), and the Additional
            Shares of Common Stock deemed issued as the result of the original
            issue of such Option shall not be deemed issued for the purposes of
            any subsequent adjustment of the Exercise Price; and

                  (v) In the event of any change in the number of shares of
            Common Stock issuable upon the exercise, conversion or exchange of
            any Option or Convertible Security, including, but not limited to, a
            change resulting from the antidilution provisions thereof, the
            Exercise Price then in effect shall forthwith be readjusted to such
            Exercise Price as would have obtained had the adjustment which was
            made upon the issuance of such Option or Convertible Security (prior
            to such change) been made upon the basis of such change, but no
            further adjustment shall be made for the actual issuance of Common
            Stock upon the exercise or conversion of any such Option or
            Convertible Security.

            (d) Adjustment of Exercise Price Upon Issuance of Additional Shares
      of Common Stock. In the event the Company shall at any time after the
      Original Issue Date issue Additional Shares of Common Stock (including
      Additional Shares of Common Stock deemed to be issued pursuant to
      paragraph (c) above), without consideration or for a consideration per
      share less than the Exercise Price in effect on the date of and
      immediately prior to such issue, then and in such event, such Exercise
      Price shall be reduced, concurrently with such issue, to a price
      (calculated to the nearest cent) calculated as follows:

                  (i) The adjusted Exercise Price shall be equal to a fraction:
            (A) the numerator of which shall be the number of shares of Common
            Stock outstanding immediately prior to such issue (including shares
            described in clause (ii) below), plus the number of shares of Common
            Stock which the aggregate consideration received by the Company for
            the total number of Additional Shares of Common Stock so issued
            would

                                       5
<PAGE>
            purchase at such Exercise Price; and (B) the denominator of which
            shall be the number of shares of Common Stock outstanding
            immediately prior to such issue (including shares described in
            clause (ii) below) plus the number of such Additional Shares of
            Common Stock so issued.

                  (ii) For the purposes of clause (i), the number of shares of
            Common Stock outstanding immediately prior to such issue shall be
            calculated on a fully diluted basis, as if all Convertible
            Securities had been fully converted into shares of Common Stock
            immediately prior to such issuance and the Warrant and any other
            outstanding Options had been fully exercised immediately prior to
            such issuance (and any resulting Convertible Securities fully
            converted into Common Stock) as of such date.

                  (iii) The applicable Exercise Price shall not be reduced at
            the time of any issuance of Additional Shares of Common Stock if the
            amount of such reduction would be an amount less than $0.01, but any
            such amount shall be carried forward and reduction with respect
            thereto shall be made at the time and together with any subsequent
            reduction which, together with such amount and any other amounts so
            carried forward, shall aggregate $0.01 or more.

            (e) Determination of Consideration. For purposes of paragraph (d),
      the consideration received by the Company for the issue of any Additional
      Shares of Common Stock shall be computed as follows:

                  (i) Cash and Property: Such consideration shall:

                        (A) insofar as it consists of cash, be computed at the
                  aggregate of cash received by the Company;

                        (B) insofar as it consists of property other than cash,
                  be computed at the fair market value thereof at the time of
                  such issue, as determined in good faith by the Board of
                  Directors; and

                        (C) in the event Additional Shares of Common Stock are
                  issued together with other shares or securities or other
                  assets of the Company for consideration which covers both, be
                  the proportion of such consideration so received, computed as
                  provided in clauses (A) and (B) above, as determined in good
                  faith by the Board of Directors.

                  (ii) Options and Convertible Securities. The consideration per
            share received by the Company for Additional Shares of Common Stock

      16. Representations and Warranties of Company. The Company represents

            (a) The execution and delivery of this Warrant has been duly
      authorized by the Company's Board of Directors and constitutes the legal,
      valid and binding obligation of the Company enforceable against the
      Company in accordance with its terms, except as enforcement thereof may be
      limited by bankruptcy, insolvency, or other laws affecting the enforcement
      of creditors' rights in general and except that the enforceability of the
      obligations hereunder is subject to general principals of equity
      (regardless of whether such enforceability is considered in a proceeding
      at equity or at law). Neither the execution nor the delivery of this
      Warrant, nor fulfillment of nor compliance with the terms and provisions
      of this Warrant, nor the issuance of Shares upon exercise of the Warrant,
      will violate the terms of the certificate of incorporation or by-laws of
      the Company or, to the best of the Company's knowledge, any agreement
      (including any agreement with stockholders), instrument, judgment, decree
      or statute to which the Company is subject.

            (b) As of December 31, 2002, the authorized capital stock of the
      Company consisted of (i) 99,300,000 shares of Common Stock, $0.001 par
      value per share, 95,000,000 shares of which are designated as Class A
      Common Stock, of which 31,885,896 shares are issued and outstanding, and
      4,300,000 shares of which are designated as Class B Common Stock, of which
      3,869,570 shares are issued and outstanding, and (ii) 10,000,000 shares of
      Preferred Stock, $0.001 par value per share 600,000 shares of which are
      designated as Series A Cumulative Convertible Preferred Stock, of which
      39,544 shares are issued and outstanding.

            (c) Except as set forth in subparagraph (b) above, and in
      registration statements filed by the Company under the Act or in any
      report filed by the Company under the Securities Exchange Act of 1934, as
      amended, the Company has not authorized any rights (either preemptive or
      other) or options to subscribe for or purchase from the Company, or any
      warrants or other agreements providing for or requiring the issuance by
      the Company of, any capital stock or any securities convertible into or
      exchangeable for its capital stock.

            (d) Sufficient shares of authorized but unissued shares of Common
      Stock of the Company have been reserved by appropriate corporate action
      with the prospective exercise of the Warrant, and, the issuance of either
      the Warrant or the shares of Common Stock upon exercise of the Warrant
      will not require any further corporate action by the stockholders or
      directors of the Company, will not be subject to preemptive rights (unless
      the exercise of the same has been irrevocably waived) in any present
      stockholders of the Company and will not conflict with any provision of
      any agreement to which the Company is a party or by which it is bound, and
      such Common Stock, when issued upon exercise of the Warrant in accordance
      with its terms, will be duly authorized, fully paid and non-assessable.

      17. Registration Rights.

            (a) Piggy Back Registration Rights. If (but without any obligation
      to do so) the Company shall determine to register (a "Company
      Registration") any of its securities for its own account or for any other
      person (other than a registration under the Act of shares issued in
      connection with any acquisition of any entity or business, shares issuable
      solely upon the exercise of stock options, or shares issuable solely
      pursuant to employee benefit plans or arrangements, including registration
      statements on Form S-4, S-8 or any successor form), the Company shall do
      the following:

                                       9
<PAGE>
                  (i) promptly give the Holder written notice thereof (which
            shall include a list of the jurisdictions in which the Company
            intends to attempt to register or qualify such securities under the
            applicable blue sky or other state securities laws); and

                  (ii) include among the securities which it then registers or
            qualifies all Registrable Securities (as defined below) specified in
            a written request or requests, made within fifteen (15) days after
            receipt of the written notice from the Company, by the Holder. The
            Holder shall have the right to withdraw its request for inclusion of
            its Registrable Securities in any registration statement by giving
            written notice to the Company of its request to withdraw. The
            Company may withdraw a Company Registration at any time prior to the
            time it becomes effective whether or not the Holder has elected to
            include Registrable Securities (as defined below) in such
            registration. For purposes of this Warrant, the term "Registrable
            Securities" shall mean all shares of Common Stock issued and
            issuable upon exercise of the Warrant; provided however, that shares
            of Common Stock which are "Registrable Securities" shall cease to be
            Registrable Securities (a) upon any sale pursuant to a registration
            statement under the Act, Section 4(1) of the Act or Rule 144
            promulgated under the Act or (b) at such time as such shares of
            Common Stock are freely saleable under Rule 144(k) promulgated under
            the Act (or a successor provision).

            (b) Limitations of Registration. If and to the extent that the
      Holder shall have, at the time of the delivery of the written request
      referred to in subparagraph (a) above, no present intention of selling or
      distribution, the Company shall be obligated to effect such registration,
      qualification or compliance with respect to the Holder's Registrable
      Securities only if and to the extent, in each case, that such
      registration, qualification and compliance are at the time permitted by
      the applicable statutes or rules and regulations thereunder or the
      practices of the governmental authority concerned.

            (c) Registration Procedures. In the case of each registration,
      qualification or compliance pursuant to this Section 17, the Company will
      keep the Holder advised in writing as to the initiation of proceedings for
      such registration, qualification and compliance and as to the completion
      thereof, and will advise the Holder, upon written request, of the progress
      of such proceedings. At the expense of the Company, the Company will (i)
      keep such registration, qualification and compliance current and effective
      for a period of the earlier of (A) 120 days, or (B) until the Holder has
      completed the distributions relating thereto, including, without
      limitation, the filing of post-effective amendments and supplements to any
      registration statement or prospectus, as necessary to permit the sale or
      distribution of Registrable Securities not theretofore sold or
      distributed, and (ii) take all necessary action under any applicable blue
      sky or other state securities laws to permit such exercise, sale or
      distribution, all as reasonably requested by such Holder; provided,
      however, that the Company shall not be required in connection therewith to
      qualify as a foreign corporation in any jurisdiction in which it is not
      now so qualified or to take any action that would subject it to general
      consent to service of process or taxation. The Company shall not be
      required to file, cause to become effective or maintain the effectiveness
      of any registration statement that contemplates a distribution of
      securities on a delayed or continuous basis pursuant to Rule 415 under the
      Act.

            (d) Registration Rights. Anything to the contrary in Section 17
      notwithstanding, in connection with any Company Registration, the Company
      shall not be required to include any of the Holder's Registrable
      Securities in such Company

                                       10
<PAGE>
      Registration unless the Holder accepts the terms of the underwriting as
      agreed upon between the Company and the underwriters selected by it (or by
      other persons entitled to select the underwriters), and then only in such
      quantity as the underwriters determine in their sole discretion will not
      jeopardize the success of the offering by the Company or will not
      adversely affect the aggregate proceeds to the Company from the offering.
      If the total amount of securities, including Registrable Securities and
      all other securities requested to be included in such offering by any
      stockholder of the Company, exceeds the amount of securities that the
      underwriters determine in their sole discretion is compatible with the
      success of the offering or the aggregate proceeds to the Company from the
      offering, then the number of Shares to be offered for the account of the
      Holder and all such other persons participating in such registration shall
      be reduced (to zero if necessary) or limited pro rata in proportion to the
      respective number of Shares requested to be registered by the Holder and
      each other person to reduce the total number of Shares requested to be
      included in such offering to the number of Shares, if any, recommended by
      such underwriters.

            (e) Indemnification. The Company will indemnify, defend and hold
      harmless the Holder to the fullest extent that such agreement is
      enforceable under applicable law against all claims, losses, damages and
      liabilities (or actions in respect thereof) arising out of or based on any
      untrue statement (or alleged untrue statement) of material fact contained
      therein (or in any related registration statement, notification or the
      like) or any omission (or alleged omission) to state therein a material
      fact required to be stated therein or necessary to make the statements
      therein not misleading, or any violation by the Company of any rule or
      regulation promulgated under the Act applicable to the Company and
      relating to action or inaction required of the Company in connection with
      any such registration, qualification or compliance, and will reimburse the
      Holder for any legal or any other expenses reasonably incurred in
      connection with investigating or defending any such claim, loss, damage,
      liability or action provided, however, that the Company will not be liable
      in any such case to the extent that any such claim, loss, damage or
      liability arises out of or is based on any untrue statement or omission
      based upon written information furnished to the Company by an instrument
      duly executed by the Holder and stated to be specifically for use therein.

            (f) The Holder will indemnify, defend and hold harmless the Company
      to the fullest extent that such agreement is enforceable under applicable
      law against all claims, losses, damages and liabilities (or actions in
      respect thereof) arising out of or based on any untrue statement (or
      alleged untrue statement) of material fact contained therein (or in any
      related registration statement, notification or the like) or any omission
      (or alleged omission) to state therein a material fact required to be
      stated therein or necessary to make the statements therein not misleading,
      or any violation by the Holder of any rule or regulation promulgated under
      the Act applicable to the Holder and relating to action or inaction
      required of the Holder in connection with any such registration,
      qualification or compliance, and will reimburse the Company for any legal
      or any other expenses reasonably incurred in connection with investigating
      or defending any such claim, loss, damage, liability or action, in each
      case to the extent (and only to the extent) that such claims, losses,
      damages, liabilities and actions relate to reliance on any untrue
      statement or omission based upon written information furnished to the
      Company by an instrument duly executed by the Holder and stated to be
      specifically for use in the registration statement, provided, however,
      that such Holder's obligations hereunder shall be limited to an amount
      equal to the proceeds received by such Holder of the Registrable
      Securities sold in such registration.

            (g) Notwithstanding the foregoing, to the extent that the provisions
      on indemnification contained in the underwriting agreement entered into in
      connection with a

                                       11

all or substantially all of the Company's assets, and all of the obligations of
the Company relating to the Shares issuable upon exercise of this Warrant shall
survive the exercise and termination of this Warrant and all of the covenants
and agreements of the Company shall inure to the benefit of the successors and
assigns of the Holder.

Agreement shall be effective unless in writing and signed by the Company and
Holder.

      20. Counterparts. This Agreement may be executed in any number of
counterparts and each such counterpart shall for all purposes be deemed to be an
original, and all such counterparts shall together constitute but one and the
same instrument.

accordance with, and the rights of the parties shall be governed by, the laws of
the Commonwealth of Massachusetts.

      22. Entire Agreement. This Warrant constitutes the entire agreement among

other written or oral agreements relating to the subject matter hereof existing
among any of the parties hereto are expressly cancelled, including, but not
limited to, the Prior Warrant.

continuance of an Event of Default, the Lenders may require accrued interest to
be payable on demand or at regular intervals more frequent than each Interest
Payment Date. All payments of interest hereunder shall be made to the Agent for
the account of each Lender in accordance with such Lender's Percentage Interest
therein. In addition, any and all interest that has previously accrued as a
result of Events of Default which occurred under the original Credit Agreement
dated December 30, 1999 (and aggregating approximately $723,400) shall be paid
to the Agent for the account of the Lenders in cash on the Maturity Date unless
waived and such waiver shall be granted only if the Accrued Interest Waiver
Conditions are satisfied at all times prior to the Payment in Full of all Credit
Obligations.

            Loan, on each Payment Date, an amount equal to interest computed at
            the Commitment Fee Rate as of such Payment Date on the amount by

            fee equal to $700,000, which fee shall be fully earned on the date

Notwithstanding the foregoing, the Company's obligation to pay any then unpaid
and not yet due installment of the $100,000 Agency Fee shall be forgiven to the
extent such fees are not yet due pursuant to the scheduled payment dates set
forth in this Section 3.2.3 if the Credit Obligations are Paid In Full on or

            stated maturity, by acceleration or otherwise), the Company shall

            (5%) of the amount of such late payment (the "Late Fee").

3.3.  Changes in Circumstances; Yield Protection.

<PAGE>
                  3.3.2. Taxes. All payments of the Credit Obligations shall be
            made without set-off or counterclaim and free and clear of any
            deductions, including deductions for Taxes, unless the Company is
            required by law to make such deductions. If (a) any Lender shall be
            subject to any Tax with respect to any payment of the Credit
            Obligations or its obligations hereunder or (b) the Company shall be
            required to withhold or deduct any Tax on any payment on the Credit
            Obligations, then such Lender may claim compensation from the
            Company under Section 3.4.5 to the extent such Lender is then in
            compliance with any applicable requirements of Section 17. Whenever
            Taxes must be withheld by the Company with respect to any payments
            of the Credit Obligations, the Company shall promptly furnish to the
            Agent for the account of the applicable Lender official receipts (to
            the extent that the relevant governmental authority delivers such
            receipts) evidencing payment of any such Taxes so withheld. If the
            Company fails to pay any such Taxes when due or fails to remit to
            the Agent for the account of the applicable Lender the required
            receipts evidencing payment of any such Taxes so withheld or
            deducted, the Company shall indemnify the affected Lender for any
            incremental Taxes and interest or penalties that may become payable
            by such Lender as a result of any such failure. In the event any
            Lender receives a refund of any Taxes for which it has received
            payment from the Company under this Section 3.4.2, such Lender shall
            promptly pay the amount of such refund to the Company, together with
            any interest thereon actually earned by such Lender.

                  3.3.3. Capital Adequacy. If any Lender shall determine that
            compliance by such Lender with any Legal Requirement regarding
            capital adequacy of banks or bank holding companies has or would
            have the effect of reducing the rate of return on the capital of
            such Lender and its Affiliates as a consequence of such Lender's
            commitment to make the extensions of credit contemplated hereby, or
            such Lender's maintenance of the extensions of credit contemplated
            hereby, to a level below that which such Lender could have achieved
            but for such compliance (taking into consideration the policies of
            such Lender and its Affiliates with respect to capital adequacy
            immediately before such compliance and assuming that the capital of
            such Lender and its Affiliates was fully utilized prior to such
            compliance) by an amount deemed by such Lender to be material, then
            such Lender may claim compensation from the Company under Section
            3.4.5.

                  3.3.4. Regulatory Changes. If any Lender shall determine that
            (a) any change in any Legal Requirement (including any new Legal
            Requirement) after the date hereof shall directly or indirectly (i)
            reduce the amount of any sum received or receivable by such Lender
            with respect to the Loan or the return to be earned by such Lender
            on the Loan, (ii) impose a cost on such Lender or any Affiliate of
            such Lender that is attributable to the making or maintaining of, or
            such Lender's commitment to make, its portion of the Loan, or (iii)
            require such Lender or any Affiliate of such Lender to make any
            payment on, or calculated by reference to, the gross amount of any
            amount received by such Lender under any Credit Document (other than
            Taxes or income or franchise taxes), and (b) such reduction,
            increased cost or payment shall not be fully compensated for by an
            adjustment in the Applicable Rate, then such Lender may claim
            compensation from the Company under Section 3.4.5.

                  3.3.5. Compensation Claims. Within fifteen (15) days after the
            receipt by the Company of a certificate from any Lender setting
            forth why it is claiming compensation under this Section 3.4 and
            computations (in reasonable detail) of the amount thereof, the
            Company shall pay to such Lender such additional amounts as such
            Lender sets forth in such certificate as sufficient fully to
            compensate it on account of the foregoing provisions of this Section
            3.4, together with interest on such amount from the 15th day after
            receipt of such certificate until payment in full thereof at the
            Overdue Reimbursement Rate. The determination by such Lender of the

                                       21
<PAGE>
            amount to be paid to it and the basis for computation thereof
            hereunder shall be conclusive so long as (a) such determination is
            made in good faith, (b) no manifest error appears therein and (c)
            the Lender uses reasonable averaging and attribution methods. The
            Company shall be entitled to replace any such Lender in accordance
            with Section 15.3.

                  3.3.6. Mitigation. Each Lender shall take such commercially
            reasonable steps as it may determine are not materially
            disadvantageous to it, including changing lending offices to the
            extent feasible, in order to reduce amounts otherwise payable by the
            Company to such Lender pursuant to Section 3.4. In addition, the
            Company shall not be responsible for costs under Section 3.4 arising
            more than ninety (90) days prior to receipt by the Company of the
            certificate from the affected Lender pursuant to such Section 3.4.

3.4.  Computations of Interest and Fees. For purposes of this Agreement,
interest, commitment fees (and any other amount expressed as interest or such
fees) shall be computed on the basis of a 365/60-day year. If any payment
required by this Agreement becomes due on any day that is not a Banking Day,
such payment shall be made on the next succeeding Banking Day. If the due date
for any payment of principal is extended as a result of the immediately
preceding sentence, interest shall be payable for the time during which payment
is extended at the Applicable Rate.

4.    Payment.

4.1.  Loans.

      (a) Revolving Loan. On the Maturity Date or any accelerated maturity of
the Revolving Loan, the Company shall pay to the Agent an amount equal to the
Revolving Loan then due, together with all accrued and unpaid interest and fees
with respect thereto and all other Credit Obligations then outstanding.

      (b) Term Loan.

                  (i) Deferred Amortization. The Company acknowledges and agrees
            that the Lenders have deferred an aggregate amount of approximately
            $2,300,000 (as of December 31, 2002) in payments against the
            outstanding principal balance of the Term Loan which were due and
            payable under the Prior Credit Agreement ("Deferred Amounts"). The
            Company further acknowledges that the cash previously paid to the
            Agent on account of the Deferred Amounts has not been applied to the
            Obligations (and the Deferred Amounts accordingly have not been
            paid) but that such cash amounts shall be deposited into the New
            Bonus Account on the Initial Closing Date, and that such Deferred
            Amounts shall now be due and payable to the Lenders in full in cash
            on the earlier of (a) the Maturity Date (whether as scheduled, by
            acceleration or otherwise); and (b) upon the closing of a
            Transaction described more fully in Section 5.3.

                  (ii) Amortization Schedule. From and after the Initial Closing
            Date, the Company shall make payments against the outstanding
            principal balance of the Term Loan in the amounts and on the dates
            set forth in the amortization schedule set forth below (the "Term
            Loan Amortization Schedule"):

provided, however, that the final installment shall be payable on the Maturity
Date in an amount equal to the aggregate principal amount of the Term Loan
outstanding on such date, together with all accrued and unpaid interest and fees
thereon. In addition, in the event that the Company at any time makes any
prepayment of the Term Loan under this Agreement, such prepayment shall not
reduce the required monthly payments set forth in the Term Loan Amortization
Schedule, but rather shall be applied in the inverse order to reduce amounts
payable on the Maturity Date.

4.2.  Contingent Required Prepayments.

                  4.2.1. Excess Credit Exposure. If at any time the Revolving
            Loan exceeds the limits set forth in Section 2.1 or the Term Loan
            exceeds the limits set forth in Section 2.2, the Company shall
            within one Banking Day after actual knowledge by a Financial Officer
            or notice from the Agent pay the amount of such excess to the Agent
            as a prepayment of the Revolving Loan or the Term Loan, as the case
            may be.

                  4.2.2. Net Asset Sale Proceeds. Upon receipt by the Company or
            any of its Subsidiaries of Net Asset Sale Proceeds, the Company
            shall within one Banking Day pay to the Agent as a prepayment of the
            Loan to be applied as provided in Section 4.5.2 the lesser of (a)
            the amount of such Net Asset Sale Proceeds or (b) the amount of the

            Banking Day pay to the Agent as a prepayment of the Loan to be

                  4.2.6. Sibson Proceeds. The Company and its Subsidiaries

            payments, earnouts and other consideration received by the Company
            or any of its Domestic Subsidiaries under the Sibson APA without
            respect to amendments thereto (the "Remaining Sibson Proceeds")
            shall immediately be delivered to the Agent for the account of the
            Lenders and applied as a mandatory permanent prepayment of the
            Revolving Loan.

            a mandatory permanent prepayment of the Revolving Loan; provided,
            however that notwithstanding the foregoing, any and all proceeds
            arising from the re-sale of software under the Persumma APA net of
            any option price incurred in connection with such re-sale (the
            "Persumma Proceeds") shall be applied as follows: (a) fifty percent
            (50%) to the Agent for the account of the Lenders and applied as a
            mandatory permanent prepayment of the Revolving Loan; and (b) fifty
            percent (50%) to the Company for working capital purposes subject to

                  4.5.2. Order of Application. In the absence of notice to the

5.    Financial Consultant; Strategic Plans.

5.1.  Financial Consultant. The Company hereby acknowledges and agrees that the
Lenders have elected in their discretion to retain, at the Company's expense, a

business operations of the Company and to analyze the Company's current and
future plans with respect to its continued business operations and the Company's
fulfillment of its obligations under the Credit Documents. The Company shall pay
the outstanding fees of the Financial Consultant on the date hereof, and
thereafter the Company shall reimburse the Lenders, or their counsel, as the
case may be, as invoiced, for all reasonable fees and expenses of the Financial
Consultant. Company agrees to cooperate with the Financial Consultant in
conducting its work, to include, without limitation, access to the Company's
facilities and books and records, and the opportunity to interview officers and
key agents and employees of the Company, including the Company's outside
auditors. The Financial Consultant may conduct any such activity without any
prior notice to the Company, provided that, unless there exists a Default or
Event of Default under this Agreement or any Credit Document, the Agent shall
provide the Company with reasonable prior notice of the first time that the
Financial Consultant expects to enter the Company's facilities.

5.2.  Business Plan. The Company shall, in good faith and as expeditiously as
possible, develop, and deliver to the Lenders on or before March 31, 2003, a

dates) with respect to the Company's business strategies and plans by business
unit, together with (a) a month-to-month Profit & Loss statement of the Company
and its Subsidiaries; and (b) cash flow projections and pro forma balance sheets
of the Company and its Subsidiaries on a Consolidated and Consolidating basis.

5.3.  Investment Banking Firm. The Company shall retain an investment banking
firm to undertake the effectuation of one or more transactions (each, a
"Transaction") that will generate liquidity for the Company and its Subsidiaries
sufficient to timely satisfy all of the Credit Obligations owed to the Agent and
Lenders by the Company and its Subsidiaries. In connection with the foregoing,
the Company shall deliver to the Agent and Lenders the following items on or
before the following dates, each in form and substance satisfactory to the Agent

            letter between the Company and such investment banking firm;

            (b)   On or before April 30, 2003, a final offering memorandum for
            soliciting Transactions and a detailed written plan as to the
            Company's efforts to effectuate one or more Transactions sufficient
            to satisfy the Company's liquidity needs; and

            (c)   On or before the date that is one week prior to each regularly
            schedule payment date under the Term Loan Amortization Schedule, a
            detailed written status report on the Company's efforts and progress
            towards effectuating one or more Transactions.

                                    deferrals and the New Lender's
                                    then-outstanding $4,000,000 of principal
                                    owing under the Junior Credit Participation
                                    Agreement (and applied in the inverse order
                                    of maturity to principal installments due to

                                    the then-outstanding Loans and any
                                    then-outstanding Credit Obligations, unless
                                    the Agent and Lenders agree (in writing in
                                    their sole and absolute discretion) to
                                    permit the Company to use such funds for
                                    other lawful purposes in accordance with a
                                    written business or strategic plan which has
                                    also been approved by the Agent and Lenders
                                    (in writing in their sole and absolute
                                    discretion).

Distributions shall be made completely in each level of priority before any
distribution is made in any lower level. To the extent that funds are
insufficient to completely satisfy each level of distribution, they shall be
made pro rata in that level to the persons entitled to such distribution.

6.    Lexecon Employee Agreements. On or before the Initial Closing Date, the
Company shall enter an employment agreement and covenants-not-to-compete through
December 31, 2008 with each of Dennis Carlton and Daniel Fischel in
substantially the form of the agreements attached as Exhibits 6(a) and 6(b)
hereto (the "Lexecon Employment Agreements"). The Company's failure to timely
satisfy any of its obligations under the Lexecon Employment Agreements shall
constitute an Event of Default hereunder (as described more fully in Section

                                       26
<PAGE>
            7.1. Principal and Accrued Interest. The principal and accrued
      interest owed to Knowledge Universe, on account of the Junior Secured
      Indebtedness, as of December 31, 2002, is $47,748,591.99. Knowledge
      Universe shall not at any time extend credit to the Company or any
      Subsidiary in an aggregate principal amount in excess of such amount;
      provided, however, Knowledge Universe may extend credit to the Company or
      any of its Subsidiaries in the form of PIK Interest.

                  7.1.1. Reaffirmation of Guaranty and Related Letter of Credit.
            Knowledge Universe hereby acknowledges and reaffirms its liability
            for all payment and performance obligations of the Company and its
            Subsidiaries to the Agent and the Lenders, now existing or hereafter
            arising, pursuant to the terms of the Knowledge Universe Guaranty as
            amended hereby. In addition, Knowledge Universe also acknowledges
            and reaffirms its supporting Irrevocable Letter of Credit dated
            April 16, 2001, as amended through the date of this Agreement, a
            true and accurate copy of which is attached as Exhibit 7.1.1.

                  7.1.2. Knowledge Universe Subordination. Knowledge Universe
            acknowledges and agrees that the Junior Secured Indebtedness, and
            the rights of Knowledge Universe against the Company and the
            Guarantors, and any obligation owed to Knowledge Universe arising
            out of or in connection with the Junior Secured Indebtedness or any
            document executed or delivered in connection therewith, shall be and
            hereby is subordinated to the prior Payment In Full of all Credit
            Obligations. Except as set forth in Section 10.10.2 hereof,
            Knowledge Universe agrees that neither the Company nor any Guarantor
            shall, directly or indirectly, by payment, distribution, set-off,
            recoupment or otherwise, pay or distribute any cash, securities or
            other property on account of the Junior Secured Indebtedness until
            the later of (i) the Maturity Date (whether as scheduled, by
            acceleration or otherwise); and (ii) the date upon which the Credit
            Obligations owed to the Agent and the Lenders have been Paid In Full
            in cash. The Junior Secured Indebtedness is subordinate to liens and
            rights of payment on the same terms as set forth herein and in the
            Credit Documents to any replacement or successor Senior Lender, such
            as in connection with or refinancing of all or a portion of the
            Credit Obligations, without fee, delay or other concessions.

                  7.1.3. Turnover of Distributions. If, notwithstanding the
            preceding Section 7.1.2 and subject to Section 10.10.2 below,
            Knowledge Universe shall receive any Distributions in respect of
            Junior Secured Indebtedness before all Credit Obligations have been
            Paid In Full, Knowledge Universe shall hold the same in trust and
            promptly transfer and turnover all such Distributions to the Agent
            for application to the payment or satisfaction of the Credit
            Obligations as provided in this Agreement.

                  7.1.4. Conversion of Preferred Stock. Knowledge Universe may
            restructure, exchange or convert its (a) existing preferred stock in
            the Company into any equity or debt securities of the Company, or
            (b) its existing Debentures into any preferred stock of the Company;
            provided that in either case (a) and (b) the Company shall not,
            directly or indirectly, by payment, distribution, set-off,
            recoupment or otherwise, pay or distribute any cash, securities or
            other property on account of any of such indebtedness owing by
            Company to Knowledge Universe (except for Distributions of PIK
            Interest), until the later of (x) the Maturity Date (whether as
            scheduled, by acceleration or otherwise); and (y) the date upon
            which the Credit Obligations owed to the Agent and the Lenders have
            been Paid In Full in cash; and, provided further, that any and all
            of such indebtedness shall be deemed to be Junior Secured
            Indebtedness, which is subordinated in priority and payment to the
            Loans, as evidenced by documentation satisfactory to the Agent and
            Lenders in their sole and absolute discretion. In addition, any and
            all indebtedness owing by the Company to Knowledge Universe shall
            not at any time exceed $60,000,000 (exclusive of the

                                       27
<PAGE>
            $5,000,000 loaned pursuant to the Junior Credit Participation
            Agreement) in the aggregate (exclusive of PIK Interest and accrued
            Interest).

8.    Bonus Matters.

      8.1.  Bonus Obligations. Company and its Subsidiaries have no employment
agreements other than those described in the table attached hereto as Exhibit
8.1, and which Exhibit 8.1 specifies (a) the name of each employee, (b) the
name, date and maturity date of such employee's respective employment agreement,
and (c) the expected bonus compensation owing to such employee during the term
of this Agreement. During the term of this Agreement, neither the Company nor
its Subsidiaries shall extend or modify any of the employment agreements
described on Exhibit 8.1 without the prior written consent of Agent and Lenders
which may be granted or withheld by them in their discretion. In addition,
during the term of this Agreement, neither the Company nor its Subsidiaries
shall make any payments, including but not limited to regularly scheduled
payments of principal, interest or other charges, on account of any subordinated
debt, management fees to affiliates, dividends, bonus compensation to officers,
including but not limited to special incentive bonuses, retention or other
programs or charges, and whether or not such programs, bonuses or charges were
previously announced (the "Bonus Obligations"), except for the following:

            (a)   In Calendar Year 2003 (For Services Performed In Calendar Year
            2002):

                  (i)   Lexecon Employees. The Company may pay bonus
            compensation and profit sharing contributions owing to employees of
            Lexecon, set forth on Company's New Bonus Schedule (totaling in the
            aggregate approximately $6,400,000) from its cash flow; and

                  (ii)  Headquarters. The Company may pay bonus compensation
            owing to employees of the Company's "Headquarters" set forth on
            Company's New Bonus Schedule (totaling in the aggregate
            approximately $475,000) on or after January 31, 2003 from its cash
            flow; and

            (b)   In Calendar Year 2004 (For Services Performed In Calendar Year
            2003):

                        the Company may pay bonus compensation and profit
            sharing contributions owing to employees of Lexecon and/or
            "Headquarters", which are first approved by the Lenders in writing
            in their discretion on or before the respective dates of such
            payments.

      The Company and its Subsidiaries agree that they shall not pay Bonus
Obligations in excess of the amounts set forth on its New Bonus Schedule unless
the Agent and the Lenders have issued their prior written consent, which consent
may be granted or withheld by the Agent and the Lenders in their discretion. The
Company and its Subsidiaries further acknowledge and agree that all Bonus
Obligations shall be and are expressly subordinate and junior in right of
payment and exercise of remedies to the Credit Obligations owing to the Agent
and the Lenders.

                                       28

8.2.  Bonus Accounts.

      (a) Existing Bonus Account. On the Initial Closing Date the Agent and
Lenders shall release an aggregate amount of $4,200,682 currently held in the
Bonus Account established pursuant to Section 8.2 of the Prior Credit Agreement
for distribution to the following parties designated by the Company:

            (i) $100,000 to Kirkland & Ellis for legal fees and expenses in

      negotiation and documentation of his Employment Agreement dated the date
      hereof and attached hereto as Exhibit 6(a);

            (ii) $100,000 to Kirkland & Ellis for legal fees and expenses
      incurred in connection with its representation of Daniel Fischel in
      respect of the negotiation and documentation of his Employment Agreement
      dated the date hereof and attached hereto as Exhibit 6(b); and

            (iii) $1,031,175.79 to Dennis Carlton in respect of his pro rata
      share of the Company's bonus accruals for its fiscal year 2002;

      share of the Company's bonus accruals for its fiscal year 2002;

            (v) $1,918,327.01 or such other amount agreed to by Company and
      Lenders to the Company's operating account number 275-05843.

      (b) New Bonus Account. On or before the Initial Closing Date, the Company
shall establish with the Agent a segregated account subject to Lenders' liens,
and which shall thereafter be funded by the Company in cash in an amount equal
to the Agreed Percentage (as defined below) of all employee bonuses which are
earned but unpaid in 2003 (except any accrued bonuses not subject to this
Section 8.2, as designated in their discretion by the Agent and the Lenders in
writing) ("New Bonus Account"), which New Bonus Account shall disbursed by the
Company only to fund such bonuses, and thereafter the Company shall deposit
additional cash into the New Bonus Account if additional bonuses are earned
and/or accrued and not immediately paid. The Agreed Percentage referred to in
this Section 8.2 shall mean an amount equal to the dollar amount of all such
accrued and unpaid bonuses, plus in each calendar month an additional amount
equal to the then applicable percentage of such accrued and unpaid bonuses set
forth in the row titled "Escrow Earned and Unpaid Bonus Percentage" in Company's
forecasts dated December 30, 2002 and delivered to the Agent and the Lenders by
e-mail on December 30, 2002. Notwithstanding the foregoing, the Company shall be
permitted to use the funds held in the New Bonus Account for its immediate cash
needs on account of payroll and payroll taxes up to four (4) times prior to the
Maturity Date; provided, however, that the Company shall replenish any and all
New Bonus Account funds used for such purpose in full in cash within thirty (30)
days of each such occurrence. The Company's failure to replenish the New Bonus
Account funds in full in cash within the time period set forth in the preceding
sentence shall constitute an Event of Default hereunder (as described more fully
in Section 12.1.3 hereof).

8.3.  Bonus Schedule Confidentiality. The Agent and the Lenders acknowledge and
agree that the Bonus Schedule is subject to Section 16 of this Agreement
(Confidentiality).

the initial extension of credit pursuant to Section 2 shall be subject to the
satisfaction, on or before the Initial Closing Date, of the

<PAGE>

Section 9.2. If the conditions set forth in this Section 9.1 are not met on or
prior to the Initial Closing Date, the Lenders shall have no obligation to make
any extensions of credit hereunder.

                  9.1.1. Notes. The Company shall have duly executed and
            delivered to the Agent a Revolving Note and a Term Note for each
            Lender having a Commitment with respect thereto who has requested
            delivery of a Note prior to the Initial Closing Date.

            Shares"), all pursuant to the terms and conditions of this Section
            10.11.

            The rights of the Lenders under this Section 10.11 shall not apply
      to:

            (a) capital stock of any class or series issued as a stock dividend
      exclusively to holders of stock of the same class or series or upon any
      subdivision or combination of shares of that class or series; or

            (b) capital stock of any class or series issued upon exercise of all

      of the Company outstanding as of the date hereof; or

      pursuant to any qualified or non-qualified stock option plan or other

<PAGE>
      Directors of the Company, equal to the first 30% of the outstanding stock
      of the Company, calculated on fully-diluted basis.

                  10.11.2. Notice of Issuance. The Company shall deliver written
            notice to each Lender of the terms and conditions of each
            transaction pursuant to which the Company intends to issue New
            Shares. Such notice shall be delivered to each Lender not later than
            the Banking Day thirty (30) days prior to the day upon which any
            such transaction is scheduled to be consummated. By such notice, the
            Company shall offer to sell to each Lender the applicable amount of
            securities calculated pursuant to Section 10.11.4.

                  10.11.3. Acceptance of Shares. Each Lender may accept any such
            offer made pursuant to this Section 10.11 in whole or in part by
            delivering to the Company a written agreement to make such purchase,
            specifying the amount of the securities to be purchased by such
            Lender, no later than the Banking Date ten (10) Banking Days
            following the day of receipt by such Lender of notice from the
            Company under Section 10.11.2 above. The terms and conditions,
            price, timing of closing and other provisions of such agreement by
            the Lenders shall be not less favorable to the Company than those of
            the other agreement to purchase such New Shares.

                  10.11.4. Percentage Interest. The amount of New Shares to be
            offered to each Lender for purchase pursuant to this Section 10.11
            shall, with respect to each transaction subject hereto, be allocated
            among the Lenders pro rata according to their respective Percentage
            Interests in the Loans, calculated by multiplying (a) the aggregate
            number of New Shares to be offered, times (b) each Lender's
            ownership interest in the Company immediately prior to the purchase
            of the New Shares; provided, however, that in the event either
            Lender does not wish to purchase its respective pro rata share of
            the New Shares offered by the Company, then the other Lender shall
            have the right to purchase any New Shares not purchased. The
            remaining Lender shall indicate in such remaining Lender's response
            to the New Offer whether and to what extent it desires to purchase
            more than such Lender's pro rata share, and act upon the New Offer
            as soon as practicable after receipt from the Company of notice that
            certain of the New Shares are available for oversubscription, and in
            all events within twenty (20) Banking Days after receipt of the New
            Offer.

                  10.11.5. No Accumulation. Each transaction or proposed
            issuance under this Section 10.11 is a separate transaction. The
            failure of either Lender to exercise in whole or in part any prior
            offer shall not increase its rights with respect to any future
            transaction subject hereto and the rights of either Lender under
            this Section 10.11 with respect to any transaction are reduced pro
            rata to the extent that such Lender acquires securities of the
            Company by participating directly in such transaction.

10.12. Asset Dispositions and Mergers. Neither the Company nor any of its
Subsidiaries shall merge or enter into a consolidation or sell, lease, exchange,
sell and lease back, sublease or otherwise dispose of any of its assets (or

            otherwise dispose of (a) inventory and Cash Equivalents in the

            in the ordinary course of business within 12 months by other assets
            of equal or greater value or (ii) that are no longer used or useful
            in the business of the Company or such Subsidiary, provided, however
            that the aggregate fair market value (book value, if greater) of all
            assets sold under this clause (b) in any fiscal year shall not be
            material, (c) doubtful accounts receivable for collection purposes
            in the ordinary course of business and (d) Immaterial Subsidiaries.

            consolidate or be liquidated into the Company or any other Wholly
            Owned Subsidiary of the Company so long as after giving effect to
            any such merger to which the Company is a party the Company shall be
            the surviving or resulting Person.

                  10.12.3. Licensing or leasing of assets for fair value in the
            ordinary course of business.

            evidence of beneficial ownership to any Person other than (a) the
            Company or any Wholly Owned Subsidiary of the Company, which shares
            shall have been pledged to the Agent as part of the Credit Security
            to the extent required by the Guarantee and Security Agreement, (b)

of the Company and its Subsidiaries is in substantial compliance with the
foregoing without any known conflict with the valid rights of others which has

resulting, in any Material Adverse Change.

11.14. Certain Business Representations.

                  11.14.1. Labor Relations. No dispute or controversy between
            the Company or any of its Subsidiaries and any of their respective
            employees has resulted, or is reasonably likely to result, in any
            Material Adverse Change, and neither the Company nor any of its
            Subsidiaries anticipates that its relationships with its unions or
            employees shall result, or are reasonably likely to result, in any
            Material Adverse Change. The Company and each of its Subsidiaries is
            in compliance in all material respects with all federal and state
            laws with respect to (a) non-discrimination in employment with which
            the failure to comply, in the aggregate, has resulted, or

<PAGE>
            creates a material risk of resulting, in a Material Adverse Change

            its Subsidiaries anticipate that the future expenditures, if any, by
            the Company and its Subsidiaries needed to meet the provisions of
            any federal, state or foreign governmental statutes, orders, rules
            or regulations shall be so burdensome as to result, or create a

Multiemployer Plan and each Plan that constitutes a "defined benefit plan" (as
defined in ERISA) are set forth in Exhibit 11.14 (as from time to time hereafter
supplemented in accordance with Sections 10.4.1 and 10.4.2). Each ERISA Group
Person has met all of the material funding standards applicable to all Plans
that are not Multiemployer Plans, and no condition exists which would permit the
institution of proceedings to terminate any Plan that is not a Multiemployer
Plan under Section 4042 of ERISA. To the knowledge of the Company and each

            Environmental Law in effect in any jurisdiction in which any
            properties of the Company or any of its Subsidiaries are located or
            where any of them conducts its business, and with all applicable
            published rules and regulations (and applicable standards and
            requirements) of the federal Environmental Protection Agency and of
            any similar agencies in states or foreign countries in which the
            Company or its Subsidiaries conducts its business other than those
            which in the aggregate have not resulted, and do not create a
            material risk of resulting, in a Material Adverse Change.

            knowledge of the Company, no Hazardous Material is present in any
            real property currently or formerly owned or operated by the Company
            or any of its Subsidiaries except that which has not resulted, and

            (a) commence a voluntary case under the Bankruptcy Code or
      authorize, by appropriate proceedings of its board of directors or other
      governing body, the commencement of such a voluntary case;

            (b) (i) have tided against it a petition commencing an involuntary
      case under the Bankruptcy Code that shall not have been dismissed within
      sixty (60) days after the date on which such petition is filed, or (ii)

      failing to deny the material allegations of such a petition or seeking,

<PAGE>
            (c) seek relief as a debtor under any applicable law, other than the
      Bankruptcy Code, of any jurisdiction relating to the liquidation or

      rights of creditors, or consent to or acquiesce in such relief;

            (d) have entered against it an order by a court of competent

            (e) make an assignment for the benefit of, or enter into a
      composition with, its creditors, or appoint, or consent to the appointment
      of, or suffer to exist a receiver or other custodian for, all or a
      substantial portion of its property.

12.2. Certain Actions Following an Event of Default. If any one or more Events
of Default shall occur and be continuing, then in each and every such case:

                  12.2.1. Terminate Obligation to Extend Credit. Upon written
            request of the Required Lenders, the Agent shall terminate the
            obligations of the Lenders to make any further extensions of credit
            under the Credit Documents by furnishing notice of such termination
            to the Company; provided, however, that if a Bankruptcy Default
            shall have occurred, the obligations of the Lenders to make any
            further extensions of credit under the Credit Documents shall
            automatically terminate.

                  12.2.2. Specific Performance; Exercise of Rights. Upon written
            request of the Required Lenders, the Agent shall proceed to protect
            and enforce the Lenders' rights by suit in equity, action at law
            and/or other appropriate proceeding, either for specific performance
            of any covenant or condition contained in this Agreement or any
            other Credit Document (other than Hedge Agreements from time to time
            in effect) or in any instrument or assignment delivered to the
            Lenders pursuant to this Agreement or any other Credit Document
            (other than Hedge Agreements from time to time in effect), or in aid
            of the exercise of any power granted in this Agreement or any other
            Credit Document (other than Hedge Agreements from time to time in
            effect) or any such instrument or assignment.

                  12.2.3. Acceleration. Upon written request of the Required
            Lenders, the Agent shall by notice in writing to the Company declare
            all or any part of the unpaid balance of the Credit Obligations
            (other than amounts under Hedge Agreements from time to time in
            effect) then outstanding to be immediately due and payable;
            provided, however, that if a Bankruptcy Default shall have occurred,
            the unpaid balance of the Credit Obligations (other than amounts
            under Hedge Agreements from time to time in effect) shall
            automatically become immediately due and payable.

                  12.2.4. Enforcement of Payment; Credit Security; Setoff. Upon
            written request of the Required Lenders, the Agent shall proceed to
            enforce payment of the Credit Obligations in such manner as it may
            elect, and to realize upon any and all rights in the Credit
            Security. The Lenders may offset and apply toward the payment of the
            Credit Obligations (and/or toward the curing of any Event of
            Default) any Indebtedness from the Lenders to the respective
            Obligors, including any Indebtedness represented by deposits in any
            account maintained with the Lenders, regardless of the adequacy of
            any security for the Credit Obligations. The Lenders shall have no
            duty to determine the adequacy of any such security in connection
            with any such offset.

                                       56
<PAGE>
                  12.2.5. Cumulative Remedies. To the extent not prohibited by
            applicable law which cannot be waived, all of the Lenders' rights
            hereunder and under each other Credit Document shall be cumulative.

12.3. Annulment of Defaults. Once an Event of Default has occurred, such Event
of Default shall be deemed to exist and be continuing for all purposes of the
Credit Documents (other than Hedge Agreements from time to time in effect) until
the Required Lenders or the Agent (with the consent of the Required Lenders)
shall have waived such Event of Default in writing, stated in writing that the
same has been cured to such Lenders' reasonable satisfaction or entered into an
amendment to this Agreement which by its express terms cures such Event of
Default, at which time such Event of Default shall no longer be deemed to exist
or to have continued. No such action by the Lenders or the Agent shall extend to
or affect any subsequent Event of Default or impair any rights of the Lenders
upon the occurrence thereof. The making of any extension of credit during the
existence of any Default or Event of Default shall not constitute a waiver
thereof.

12.4. Waivers. To the extent that such waiver is not prohibited by the
provisions of applicable law that cannot be waived, each of the Company and the
other Obligors waives:

            (a) all presentments, demands for performance, notices of
      nonperformance (except to the extent required by this Agreement or any
      other Credit Document), protests, notices of protest and notices of
      dishonor;

            (b) any requirement of diligence or promptness on the part of the
      Agent or any Lender in the enforcement of its rights under this Agreement
      or any other Credit Document;

            (c) any and all notices of every kind and description which may be
      required to be given by any statute or rule of law; and

            (d) any defense (other than indefeasible payment in full) which it
      may now or hereafter have with respect to its liability under this
      Agreement or any other Credit Document or with respect to the Credit
      Obligations.

13. Expenses; Indemnity; Release of Claims.

13.1. Expenses. Whether or not the transactions contemplated hereby shall be
consummated, the Company shall pay:

            (a) all reasonable expenses of the Agent and the Syndication Agent
      (including the out-of-pocket expenses related to forming the group of
      Lenders and reasonable fees and disbursements of the counsel to the Agent
      and the Syndication Agent) in connection with the negotiation, preparation
      and duplication of this Agreement and each other Credit Document,
      examinations by, and reports of, the Agent's commercial financial
      examiners, fixed asset appraisers and environmental consultants, the
      transactions contemplated hereby and thereby and amendments, waivers,

            (b) all recording and filing fees and transfer and documentary stamp
      and similar taxes at any time payable in respect of this Agreement, any
      other Credit Document, any Credit Security or the incurrence of the Credit
      Obligations; and

            (c) all other reasonable expenses incurred by the Agent, the Lenders
      or the holder of any Credit Obligation in connection with the enforcement
      of any rights hereunder or under any other Credit Document or any work-out
      negotiations relating to the Credit Obligations, including

                                       57
<PAGE>
      costs of collection and reasonable attorneys' fees (including a reasonable
      allowance for the hourly cost of attorneys employed by the Lenders on a
      salaried basis) and expenses.

13.2. General Indemnity. The Company and each Guarantor hereby each indemnifies
the Lenders and the Agent and holds them harmless from any liability, loss or
damage resulting from the violation by the Company of Section 2.4. In addition,
the Company hereby indemnifies each Lender, the Agent, the Syndication Agent,
each of the Lenders' or the Agent's or the Syndication Agent's directors,
officers, employees, agents, attorneys, accountants, consultants and each
Person, if any, who controls any Lender or the Agent (each Lender, the Agent and
each of such directors, officers, employees, agents, attorneys, accountants,
consultants and control Persons is referred to as an "Indemnified Party") and
holds each of them harmless from and against any and all claims, damages,
liabilities and reasonable expenses (including reasonable fees and disbursements
of counsel with whom any Indemnified Party may consult in connection therewith
and all reasonable expenses of litigation or preparation therefor) which any
Indemnified Party may incur or which may be asserted against any Indemnified
Party relating to, arising out of or by reason of this Agreement or any other
Credit Document in connection with (a) the Indemnified Party's compliance with
or contest of any subpoena or other process issued against it in any proceeding
involving the Company or any of its Subsidiaries or their Affiliates, (b) any
litigation or investigation involving the Company, any of its Subsidiaries or
their Affiliates, or any officer, director or employee thereof, (c) the
existence or exercise of any security rights with respect to the Credit Security
in accordance with the Credit Documents, or (d) this Agreement, any other Credit
Document or any transaction contemplated hereby or thereby; provided, however,
that the foregoing indemnity shall not apply (i) to litigation commenced by the
Company against the Lenders or the Agent or the Syndication Agent which seeks
enforcement of any of the rights of the Company hereunder or under any other
Credit Document and is determined adversely to the Lenders or the Agent or the
Syndication Agent in a final nonappealable judgment or (ii) to the extent such
claims, damages, liabilities and expenses result from the Indemnified Party's
own gross negligence or willful misconduct. THE COMPANY EXPRESSLY ACKNOWLEDGES
THAT IT MAY BE REQUIRED TO INDEMNIFY PERSONS AGAINST THEIR OWN NEGLIGENCE.

13.3. Intentionally Omitted.

13.4. Release of Claims. The Company and each Guarantor hereby each releases,
waives and forever relinquishes all claims, demands, obligations, liabilities
and causes of action of whatever kind or nature, whether known or unknown, which
it has, may have, or might assert now or in the future against the Agent or the
Lenders and/or their respective, parents, affiliates, participants, affiliates,
officers, directors, employees, agents, attorneys, accountants, consultants,
successors and assigns, directly or indirectly, arising out of, based upon, or
in any manner connected with (i) any transaction, event, circumstance, action,
failure to act or occurrence of any sort or type, whether known or unknown,
which occurred, existed, was taken, permitted or begun prior to the execution of
this Agreement with respect to the Credit Obligations, the Credit Documents
and/or the administration thereof or the obligations created thereby; (ii) any
discussions, commitments, negotiations, conversations or communications with
respect to the refinancing, restructuring or collection of any Credit
Obligations; or (iii) any thing or matter related to any of the foregoing. The
inclusion of this paragraph in this Agreement, and the execution of this
Agreement by the Agent or the Lenders, does not constitute an acknowledgment or
admission by the Agent or any Lender of liability for any matter, or a precedent
upon which liability may be asserted.

14. Operations; Agent.

14.1. Interests in Credits. The Percentage Interest of each Lender in the
respective portions of the Loan, and the related Commitments, shall be computed
based on the maximum principal amount for each Lender as set forth in the
Register, as from time to time in effect. The current Percentage Interests are
set forth in Exhibit 14.1, which may be updated by the Agent from time to time
to conform to the Register.

                                       58
<PAGE>
14.2. Agent's Authority to Act, etc. Each of the Lenders appoints and authorizes
Fleet to act for the Lenders as the Lenders' Agent in connection with the
transactions contemplated by this Agreement and the other Credit Documents
(other than Hedge Agreements from time to time in effect) on the terms set forth
herein. All action in connection with the enforcement of, or the exercise of any
remedies (other than the Lenders' rights of set-off as provided in Section
12.2.4 or in any Credit Document) in respect of the Credit Obligations and
Credit Documents shall be taken by the Agent.

14.3. Company to Pay Agent, etc. The Company and each Guarantor shall be fully
protected in making all payments in respect of the Credit Obligations (other
than payments under Hedge Agreements from time to time in effect) to the Agent,
in relying upon consents, modifications and amendments executed by the Agent
purportedly on the Lenders' behalf, and in dealing with the Agent as herein
provided. The Agent may charge the accounts of the Company, on the dates when
the amounts thereof become due and payable, with the amounts of the principal of
and interest on the Loan, commitment fees and all other fees and amounts owing
under any Credit Document (other than Hedge Agreements from time to time in
effect).

14.4. Lender Operations for Advances, etc.

                  14.4.1. Advances. On each Closing Date, each Lender shall
            advance to the Agent in immediately available funds such Lender's
            Percentage Interest in the portion of the Loan advanced on such
            Closing Date prior to 12:00 noon (Boston time). If such funds are
            not received at such time, but all applicable conditions set forth
            in Section 9 have been satisfied, each Lender authorizes and
            requests the Agent to advance for the Lender's account, pursuant to
            the terms hereof, the Lender's respective Percentage Interest in
            such portion of the Loan and agrees to reimburse the Agent in
            immediately available funds for the amount thereof prior to 2:00
            p.m. (Boston time) on the day any portion of the Loan is advanced
            hereunder; provided, however, that the Agent is not authorized to
            make any such advance for the account of any Lender who has
            previously notified the Agent in writing that such Lender shall not
            be performing its obligations to make further advances hereunder;
            and provided, further, that the Agent shall be under no obligation
            to make any such advance.

                  14.4.2. Intentionally Omitted.

                  14.4.3. Agent to Allocate Payments, etc. All payments of
            principal and interest in respect of the extensions of credit made
            pursuant to this Agreement, commitment fees and other fees under
            this Agreement shall, as a matter of convenience, be made by the
            Company and the Guarantors to the Agent in immediately available
            funds by noon (Boston time) on any Banking Day. The share of each
            Lender shall be credited to such Lender by the Agent in immediately
            available funds by 2:00 p.m. (Boston time) on such Banking Day in
            such manner that the principal amount of the Credit Obligations to
            be paid shall be paid proportionately in accordance with the
            Lenders' respective Percentage Interests in such Credit Obligations,
            except as otherwise provided in this Agreement. Under no
            circumstances shall any Lender be required to produce or present its
            Notes as evidence of its interests in the Credit Obligations in any
            action or proceeding relating to the Credit Obligations.

                  14.4.4. Nonperforming Lenders. In the event that any Lender
            fails to reimburse the Agent pursuant to Sections 14.4.1 or 14.4.2
            for the Percentage Interest of such lender (a "Nonperforming
            Lender") in any credit advanced by the Agent pursuant hereto,
            overdue amounts (the "Delinquent Payment") due from the
            Nonperforming Lender to the Agent shall bear interest, payable by
            the Nonperforming Lender on demand, at a per annum rate equal to (a)
            the Federal Funds Rate for the

                                       59
<PAGE>
            first three (3) days overdue and (b) the sum of two percent (2%)
            plus the Federal Funds Rate for any longer period. Such interest
            shall be payable to the Agent for its own account for the period
            commencing on the date of the Delinquent Payment and ending on the
            date the Nonperforming Lender reimburses the Agent on account of the
            Delinquent Payment (to the extent not paid by any Obligor as
            provided below) and the accrued interest thereon (the "Delinquency
            Period"), whether pursuant to the assignments referred to below or
            otherwise. Upon notice by the Agent, the Company shall pay to the
            Agent the principal (but not the interest) portion of the Delinquent
            Payment; provided that such Delinquent Payment has been outstanding
            for no fewer than three (3) days. During the Delinquency Period, in
            order to make reimbursements for the Delinquent Payment and accrued
            interest thereon, the Nonperforming Lender shall be deemed to have
            assigned to the Agent all interest, commitment fees and other
            payments made by the Company under Section 3 that would have
            thereafter otherwise been payable under the Credit Documents to the
            Nonperforming Lender. During any period in which any Nonperforming
            Lender is not performing its obligations to extend credit under
            Section 2, the Nonperforming Lender shall be deemed to have assigned
            to each Lender that is not a Nonperforming Lender (a "Performing
            Lender") all principal and other payments made by the Company under
            Section 4 that would have thereafter otherwise been payable under
            the Credit Documents to the Nonperforming Lender. The Agent shall
            credit a portion of such payments to each Performing Lender in an
            amount equal to the Percentage Interest of such Performing Lender in
            an amount equal to the Percentage Interest of such Performing Lender
            divided by one minus the Percentage Interest of the Nonperforming
            Lender until the respective portions of the Loan owed to all the
            Lenders are the same as the Percentage Interests of the Lenders
            immediately prior to the failure of the Nonperforming Lender to
            perform its obligations under Section 2. The foregoing provisions
            shall be in addition to any other remedies the Agent, the Performing
            Lenders or the Company may have under law or equity against the
            Nonperforming Lender as a result of the Delinquent Payment as a
            result of its failure to perform its obligations under Section 2.

14.5. Sharing of Payments, etc. Each Lender agrees that (a) if by exercising any
right of set-off or counterclaim or otherwise, it shall receive payment of (i) a
proportion of the aggregate amount due with respect to its Percentage Interest
in the Loan and which is greater than (ii) the proportion received by any other
Lender in respect of the aggregate amount due with respect to such other
Lender's Percentage Interest in the Loan and (b) if such inequality shall
continue for more than ten (10) days, the Lender receiving such proportionately
greater payment shall purchase participations in the Percentage Interests in the
Loan held by the other Lenders, and such other adjustments shall be made from
time to time (including rescission of such purchases of participations in the
event the unequal payment originally received is recovered from such Lender
through bankruptcy proceedings or otherwise), as may be required so that all
such payments of principal and interest with respect to the Loan held by the
Lenders shall be shared by the Lenders pro rata in accordance with their
respective Percentage Interests; provided, however, that this Section 14.5 shall
not impair the right of any Lender to exercise any right of set-off or
counterclaim it may have and to apply the amount subject to such exercise to the
payment of Indebtedness of any Obligor other than such Obligor's Indebtedness
with respect to the Loan. Each Lender that grants a participation in the Credit
Obligations to a Credit Participant shall require as a condition to the granting
of such participation that such Credit Participant agree to share payments
received in respect of the Credit Obligations as provided in this Section 14.5.
The provisions of this Section 14.5 are for the sole and exclusive benefit of
the Lenders and no failure of any Lender to comply with the terms hereof shall
be available to any Obligor as a defense to the payment of the Credit
Obligations.

14.6. Agent's Resignation. The Agent may resign at any time by giving at least
sixty (60) days' prior written notice of its intention to do so to each of the
Lenders and the Company and upon the appointment by the Required Lenders of a
successor Agent; provided, however, that Bank of America, N.A. shall have

                                       60
<PAGE>
the right of first refusal with respect to such appointment. If no successor
Agent shall have been so appointed and shall have accepted such appointment
within forty five (45) days after the retiring Agent's giving of such notice of
resignation, then the retiring Agent may appoint a successor Agent which shall
be a bank or a trust company organized under the laws of the United States of
America or any state thereof and having a combined capital, surplus and
undivided profit of at least $100,000,000; provided, however, that any successor
Agent appointed under this sentence may be removed upon the written request of
the Required Lenders, which request shall also appoint a successor Agent. Upon
the appointment of a new Agent hereunder, the term "Agent" shall for all
purposes of this Agreement thereafter mean such successor. After any retiring
Agent's resignation hereunder as Agent, or the removal hereunder of any
successor Agent, the provisions of this Agreement shall continue to inure to the
benefit of such retiring or removed Agent as to any actions taken or omitted to
be taken by it while it was Agent under this Agreement.

14.7. Concerning the Agent.

                  14.7.1. Action in Good Faith, etc. The Agent and its officers,
            directors, employees and agents shall be under no liability to any
            of the Lenders or to any future holder of any interest in the Credit
            Obligations for any action or failure to act taken or suffered in
            good faith, and any action or failure to act in accordance with an
            opinion of its counsel shall conclusively be deemed to be in good
            faith. The Agent shall in all cases be entitled to rely, and shall
            be fully protected in relying, on instructions given to the Agent by
            the Required Lenders.

                  14.7.2. No Implied Duties, etc. The Agent shall have and may
            exercise such powers as are specifically delegated to the Agent
            under this Agreement or any other Credit Document together with all
            other powers incidental thereto. The Agent shall have no implied
            duties to any Person or any obligation to take any action under this
            Agreement or any other Credit Document except for action
            specifically provided for in this Agreement or any other Credit
            Document to be taken by the Agent.

                  14.7.3. Validity, etc. The Agent shall not be responsible to
            any Lender or any future holder of any interest in the Credit
            Obligations (a) for the legality, Validity, enforceability or
            effectiveness of this Agreement or any other Credit Document, (b)
            for any recitals, reports, representations, warranties or statements
            contained in or made in connection with this Agreement or any other
            Credit Document, (c) for the existence or value of any assets
            included in any security for the Credit Obligations, (d) for the
            effectiveness of any Lien purported to be included in the Credit
            Security, (e) for the specification or failure to specify any
            particular assets to be included in the Credit Security, or (f)
            unless the Agent shall have failed to comply with Section 14.7.1,
            for the perfection of the security interests in the Credit Security.

                  14.7.4. Compliance. The Agent shall not be obligated to
            ascertain or inquire as to the performance or observance of any of
            the terms of this Agreement or any other Credit Document; and in
            connection with any extension of credit under this Agreement or any
            other Credit Document, the Agent shall be fully protected in relying
            on a certificate of the Company as to the fulfillment by the Company
            of any conditions to such extension of credit.

                  14.7.5. Employment of Agents and Counsel. The Agent may
            execute any of its duties as Agent under this Agreement or any other
            Credit Document by or through employees, agents and
            attorneys-in-fact and shall not be responsible to any of the
            Lenders, the Company or any other Obligor for the default or
            misconduct of any such agents or attorneys-in-fact selected by the
            Agent acting in good faith. The Agent shall be entitled to advice of
            counsel concerning all matters pertaining to the agency hereby
            created and its duties hereunder or under any other Credit Document.

                                       61
<PAGE>
                  14.7.6. Reliance on Documents and Counsel. The Agent shall be
            entitled to rely, and shall be fully protected in relying, upon any
            affidavit, certificate, cablegram, consent, instrument, letter,
            notice, order, document, statement, telecopy, telegram, telex or
            teletype message or writing reasonably believed in good faith by the
            Agent to be genuine and correct and to have been signed, sent or
            made by the Person in question, including any telephonic or oral
            statement made by such Person, and, with respect to legal matters,
            upon an opinion or the advice of counsel selected by the Agent.

                  14.7.7. Agent's Reimbursement. Each of the Lenders severally
            agrees to reimburse the Agent, pro rata in accordance with such
            Lender's Percentage Interest, for any reasonable expenses not
            reimbursed by the Company or the Guarantors (without limiting the
            obligation of the Company or the Guarantors to make such
            reimbursement): (a) for which the Agent is entitled to reimbursement
            by the Company or the Guarantors under this Agreement or any other
            Credit Document, and (b) after the occurrence and during the
            continuance of a Default, for any other reasonable expenses incurred
            by the Agent on the Lenders' behalf in connection with the
            enforcement of the Lenders' rights under this Agreement or any other
            Credit Document; provided, however, that the Agent shall not be
            reimbursed for any such expenses arising as a result of its gross
            negligence or willful misconduct.

14.8. Rights as a Lender. With respect to any credit extended by it hereunder,
Fleet shall have the same rights, obligations and powers hereunder as any other
Lender and may exercise such rights and powers as though it were not the Agent,
and unless the context otherwise specifies, Fleet shall be treated in its
individual capacity as though it were not the Agent hereunder. Without limiting
the generality of the foregoing, the Percentage Interest of Fleet shall be
included in any computations of Percentage Interests. Fleet and its Affiliates
may accept deposits from, lend money to, act as trustee for and generally engage
in any kind of banking or trust business with the Company, any of its
Subsidiaries or any Affiliate of any of them and any Person who may do business
with or own an equity interest in the Company, any of its Subsidiaries or any
Affiliate of any of them, all as if Fleet were not the Agent and without any
duty to account therefor to the other Lenders.

14.9. Independent Credit Decision. Each of the Lenders acknowledges that it has
independently and without reliance upon the Agent, based on the financial
statements and other documents referred to in Section 11.2, on the other
representations and warranties contained herein and on such other information
with respect to the Company and its Subsidiaries as such Lender deemed
appropriate, made such Lender's own credit analysis and decision to enter into
this Agreement and to make the extensions of credit provided for hereunder. Each
Lender represents to the Agent that such Lender shall continue to make its own
independent credit and other decisions in taking or not taking action under this
Agreement or any other Credit Document. Each Lender expressly acknowledges that
neither the Agent nor any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates has made any representations or warranties to
such Lender, and no act by the Agent taken under this Agreement or any other
Credit Document, including any review of the affairs of the Company and its
Subsidiaries, shall be deemed to constitute any representation or warranty by
the Agent. Except for notices, reports and other documents expressly required to
be furnished to each Lender by the Agent under this Agreement or any other
Credit Document, the Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the business,
operations, property, condition, financial or otherwise, or creditworthiness of
the Company or any Subsidiary which may come into the possession of the Agent or
any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates.

14.10. Indemnification. The Lenders shall severally indemnify the Agent and its
officers, directors, employees, agents, attorneys, accountants, consultants and
controlling Persons (to the extent not reimbursed by the Obligors and without
limiting the obligation of any of the Obligors to do so), pro rata in accordance
with their respective Percentage Interests, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind

                                       62
<PAGE>
whatsoever which may at any time be imposed on, incurred by or asserted against
the Agent or such Persons relating to or arising out of this Agreement, any
other Credit Document, the transactions contemplated hereby or thereby, or any
action taken or omitted by the Agent in connection with any of the foregoing;
provided, however, that the foregoing shall not extend to actions or omissions
which are taken by the Agent with gross negligence or willful misconduct.

15. Successors and Assigns; Lender Assignments and Participations. Any reference
in this Agreement or any other Credit Document to any of the parties hereto
shall be deemed to include the successors and assigns of such party, and all
covenants and agreements by or on behalf of the Company, the other Obligors, the
Agent or the Lenders that are contained in this Agreement or any other Credit
Document shall bind and inure to the benefit of their respective successors and
assigns; provided, however, that (a) the Company and its Subsidiaries may not
assign their rights or obligations under this Agreement or any other Credit
Document except for mergers or liquidations permitted by Section 10.12, and (b)
the Lenders shall be not entitled to assign their respective Percentage
Interests in the credits extended hereunder or their Commitments except as set
forth below in this Section 15 (provided, however, that this Section 15 shall be
solely for the benefit of the Lenders and shall confer no rights in or benefits
upon the Company).

15.1. Assignments by Lenders.

                  15.1.1. Assignees and Assignment Procedures. Each Lender may,
            in compliance with applicable laws in connection with such
            assignment, but without the consent of the Company, assign to one or
            more Eligible Assignees (each, an "Assignee") all or a portion of
            its interests, rights and obligations under this Agreement and the
            other Credit Documents, including all or a portion, which must be
            pro rata between the Revolving Loan and the Term Loan, of its
            Commitment, the portions of the Loan at the time owing to it and any
            Notes held by it; provided, however, that:

                  (i) the aggregate amount of the Commitment of the assigning
            Lender subject to each such assignment to any Assignee other than
            another Lender, a Related Fund or an Affiliate of a Lender
            (determined as of the date the Assignment and Acceptance with
            respect to such assignment is delivered to the Agent) shall be not
            less than $5,000,000 and in increments of $1,000,000 (or, if less,
            the entire remaining amount of the assigning Lender's Commitment);
            and

                  (ii) the parties to each such assignment shall execute and
            deliver to the Agent an Assignment and Acceptance (the "Assignment
            and Acceptance") substantially in the form of Exhibit 15.1.1,
            together with the Note subject to such assignment and, except in the
            event of a transfer pursuant to Section 15.3, a processing and
            recordation fee of $2,500 payable to the Agent by the assigning
            Lender (or as the assigning Lender and the Assignee may otherwise
            agree between themselves).

      Upon acceptance and recording pursuant to Section 15.1.4, from and after
      the effective date specified in each Assignment and Acceptance (which
      effective date shall be at least five (5) Banking Days after the execution
      thereof unless waived by the Agent):

            (A)   the Assignee shall be a party hereto and, to the extent
                  provided in such Assignment and Acceptance, have the rights
                  and obligations of a Lender under this Agreement and

            (B)   the assigning Lender shall, to the extent provided in such
                  assignment, be released from its obligations under this
                  Agreement (and, in the case of an Assignment and Acceptance
                  covering all or the remaining portion of an assigning Lender's
                  rights and obligations under this Agreement, such Lender shall
                  cease to be a party hereto but shall continue to be entitled
                  to the benefits of Sections 3.4

                                       63
<PAGE>
                  and 13, as well as to any fees accrued for its account
                  hereunder and not yet paid).

                  15.1.2. Terms of Assignment and Acceptance. By executing and
            delivering an Assignment and Acceptance, the assigning Lender and
            the Assignee shall be deemed to confirm to and agree with each other
            and the other parties hereto as follows:

            (a) other than the representation and warranty that it is the legal
      and beneficial owner of the interest being assigned thereby free and clear
      of any adverse claim, such assigning Lender makes no representation or
      warranty and assumes no responsibility with respect to any statements,
      warranties or representations made in or in connection with this Agreement
      or the execution, legality, validity, enforceability, genuineness,
      sufficiency or value of this Agreement, any other Credit Document or any
      other instrument or document furnished pursuant hereto;

            (b) such assigning Lender makes no representation or warranty and
      assumes no responsibility with respect to the financial condition of the
      Company and its Subsidiaries or the performance or observance by the
      Company or any of its Subsidiaries of any of its obligations under this
      Agreement, any other Credit Document or any other instrument or document
      furnished pursuant hereto;

            (c) such Assignee confirms that it has received a copy of this
      Agreement, together with copies of the most recent financial statements
      delivered pursuant to Section 11.2 or Section 10.4 and such other
      documents and information as it has deemed appropriate to make its own
      credit analysis and decision to enter into such Assignment and Acceptance;

            (d) such Assignee shall independently and without reliance upon the
      Agent, such assigning Lender or any other Lender, and based on such
      documents and information as it shall deem appropriate at the time,
      continue to make its own credit decisions in taking or not taking action
      under this Agreement;

            (e) such Assignee appoints and authorizes the Agent to take such
      action as agent on its behalf and to exercise such powers under this
      Agreement as are delegated to the Agent by the terms hereof, together with
      such powers as are reasonably incidental thereto; and

            (f) such Assignee agrees that it shall perform in accordance with
      the terms of this Agreement all the obligations which are required to be
      performed by it as a Lender.

                  15.1.3. Register. The Agent shall maintain at the Boston
            Office (for this limited purpose, also as agent for the Company) a
            register (the "Register") for the recordation of (a) the names and
            addresses of the Lenders and the Assignees which assume rights and
            obligations pursuant to an assignment under Section 15.1.1, (b) the
            Percentage Interest of each such Lender as set forth in Exhibit 14.1
            and (c) the amount of the Loan owing to each Lender from time to
            time. The entries in the Register shall be conclusive, in the
            absence of manifest error, and the Company, the Agent and the
            Lenders may treat each Person whose name is registered therein for
            all purposes as a party to this Agreement. The Register shall be
            available for inspection by the Company or any Lender at any
            reasonable time and from time to time upon reasonable prior notice.

                  15.1.4. Acceptance of Assignment and Assumption. Upon its
            receipt of a completed Assignment and Acceptance executed by an
            assigning Lender and an Assignee (and any necessary consent of the
            Agent and the Company) together with the processing and recordation
            fee referred to in Section 15.1.1 and, to the extent necessary, the
            Note being assigned, the Agent shall (a) accept such Assignment and

                                       64
<PAGE>
            Acceptance, (b) record the information contained therein in the
            Register and (c) give prompt notice thereof to the Company. Within
            five (5) Banking Days after receipt of notice, the Company, at its
            own expense, shall execute and deliver to the Agent (in exchange for
            the surrendered Note if such Note must be surrendered or reissued as
            a result of such assignment) a new Note to the order of such
            Assignee in a principal amount equal to the applicable Commitment
            and Loan assumed by it pursuant to such Assignment and Acceptance.
            If the assigning Lender has retained a Commitment and Loan, its Note
            shall be deemed to be then outstanding in a principal amount equal
            to the applicable Commitment and Loan retained by it.

                  15.1.5. Federal Reserve Bank. Notwithstanding the foregoing
            provisions of this Section 11 (without the consent of or notice to
            the Agent or the Company), any Lender may at any time pledge all or
            any portion of such Lender's rights under this Agreement and the
            other Credit Documents to a Federal Reserve Bank or, in the case of
            any Lender that is a fund, to the trustee of such fund to support
            the fund's obligations to such trustee; provided, however, that no
            such pledge or assignment shall release such Lender from such
            Lender's obligations hereunder or under any other Credit Document.

                  15.1.6. Further Assurances. The Company and its Subsidiaries
            shall sign such documents and take such other actions from time to
            time reasonably requested by an Assignee to enable it to share in
            the benefits of the rights created by the Credit Documents.

15.2. Credit Participants.

            (a) Consent to Junior Credit Participation Agreement. Each of the
      Company and its Subsidiaries acknowledges that (i) on or before the
      Initial Closing Date the Lenders shall sell a junior credit participation
      in the Term Loan to New Lender in an aggregate amount of $5,000,000; (ii)
      Company's and its Subsidiaries' consent to the sale of a junior credit
      participation is not required under the Credit Agreement; and (iii) the
      Lenders' sale of the junior credit participation in the Term Loan shall
      not affect their obligations for repayment of the entire unpaid balance of
      the Credit Obligations (including, but not limited to, any portion thereof
      in respect to which the junior credit participation has been issued) in
      accordance with the terms of this Agreement or any Credit Document and
      that the respective priorities, rights, obligations and privileges of the
      Lenders and New Lender vis-a-vis each other shall be governed by the
      Junior Credit Participation Agreement.

            (b) Each Lender may, on or after the Initial Closing Date, without
      the consent of the Company or the Agent, in compliance with applicable
      laws in connection with such participation, sell to one or more commercial
      banks, other financial institutions or funds in the business of making or
      purchasing loans similar to the Credit Obligations (each a "Credit
      Participant") participations in all or a portion of its interests, rights
      and obligations under this Agreement and the other Credit Documents
      (including all or a portion of its Commitment and the Loan owing to it and
      the Notes held by it); provided, however, that:

            (c) such Lender's obligations under this Agreement shall remain
      unchanged;

            (d) such Lender shall remain solely responsible to the other parties
      hereto for the performance of such obligations;

            (e) the Credit Participant shall be entitled to the benefit of the
      cost protection provisions contained in Sections 3.4 and 13, but shall not
      be entitled to receive any greater payment thereunder than the selling
      Lender would have been entitled to receive with respect to the interest so
      sold if such interest had not been sold; and

                                       65
<PAGE>
            (f) the Company, the Agent and the other Lenders shall continue to
      deal solely and directly with such Lender in connection with such Lender's
      rights and obligations under this Agreement and, under any agreements
      between such Lender and such Credit Participant, such Lender shall retain
      the sole right as one of the Lenders to vote (and to determine how to
      vote) with respect to the enforcement of the obligations of the Obligors
      relating to the Loan and the approval of any amendment, modification or
      waiver of any provision of this Agreement (other than amendments,
      modifications, consents or waivers described in clause (b) of the proviso
      to Section 19.1, with respect to which the Credit Participant may
      determine how to vote).

Each Obligor agrees, to the fullest extent permitted by applicable law, that any
Credit Participant and any Lender purchasing a participation from another Lender
pursuant to Section 14.5 may exercise all rights of payment (including the right
of set-off), with respect to its participation as fully as if such Credit
Participant or such Lender were the direct creditor of the Obligors and a Lender
hereunder in the amount of such participation; provided, however, that such
Credit Participant may only exercise its rights of payment if the Company has
been notified that such Person is a Credit Participant.

15.3. Replacement of Lender. In the event that any Lender or, to the extent
applicable, any Credit Participant (the "Affected Lender"):

            (a) fails to perform its obligations to fund any portion of the Loan
      on any Closing Date when required to do so by the terms of the Credit
      Documents;

            (b) demands payment under the provisions of Section 3.4 in an amount
      materially in excess of the amounts with respect thereto demanded by the
      other Lenders; or

            (c) refuses to consent to a proposed amendment, modification, waiver
      or other action requiring consent of the holders of one hundred percent
      (100%) of the Percentage Interests under Section 19.1 that is consented to
      by Lenders owning at least eighty percent (80%) of the Percentage
      Interests;

then, so long as no Event of Default exists, the Company shall have the right to
seek a replacement lender which is reasonably satisfactory to the Agent (the
"Replacement Lender"). The Replacement Lender shall purchase the interests of
the Affected Lender in the Loan, and its Commitment and shall assume the
obligations of the Affected Lender hereunder and under the other Credit
Documents upon execution by the Replacement Lender of an Assignment and
Acceptance and the tender by it to the Affected Lender of a purchase price
agreed between it and the Affected Lender (or, if they are unable to agree, a
purchase price in the amount of the Affected Lender's Percentage Interest in the
Loan, or appropriate credit support for contingent amounts included therein, and
all other outstanding Credit Obligations then owed to the Affected Lender). No
assignment fee pursuant to Section 15.1.1(ii) shall be required in connection
with such assignment. Upon consummation of such assignment, the Replacement
Lender shall become party to this Agreement as a signatory hereto and shall have
all the rights and obligations of the Affected Lender under this Agreement and
the other Credit Documents with a Percentage Interest equal to the Percentage
Interest of the Affected Lender, the Affected Lender shall be released from its
obligations hereunder and under the other Credit Documents, and no further
consent or action by any party shall be required. Upon the consummation of such
assignment, the Company, the Agent and the Affected Lender shall make
appropriate arrangements so that a new Note is issued to the Replacement Lender
if it has acquired a portion of the Loan. The Company and the Guarantors shall
sign such documents and take such other actions reasonably requested by the
Replacement Lender to enable it to share in the benefits of the rights created
by the Credit Documents. Until the consummation of an assignment in accordance
with the foregoing provisions of this Section 15.3, the Company shall continue
to pay to the Affected Lender any Credit Obligations as they become due and
payable.

16. Confidentiality. Each Lender shall make no disclosure of confidential
information furnished to it by the Company or any of its Subsidiaries unless
such information shall have become public (unless such information has become
public as a result of a violation of this Section 16), except:

                                       66
<PAGE>
            (a) in connection with operations under or the enforcement of this
      Agreement or any other Credit Document to Persons who have a reasonable
      need to be furnished such confidential information in connection with the
      administration or other actions related to this Agreement and who agree,
      in a commercially customary manner, to comply with the restrictions
      contained in this Section 16 with respect to such information;

            (b) pursuant to any statutory or regulatory requirement or any
      mandatory court order, subpoena or other legal process;

            (c) to any parent or corporate Affiliate of such Lender or to any
      Credit Participant, proposed Credit Participant or proposed Assignee in
      connection with the administration or other actions related to this
      Agreement; provided, however, that any such Person shall agree, in a
      commercially customary manner, to comply with the restrictions set forth
      in this Section 16 with respect to such information;

            (d) to its independent counsel, auditors and other professional
      advisors in connection with the administration or other actions related to
      this Agreement with instruction to such Person to keep such information
      confidential; and

            (e) with the prior written consent of the Company, to any other
      Person.

17. Foreign Lenders. If any Lender is not created or organized in, or under the
laws of, the United States of America or any state thereof, such Lender shall
deliver to the Company and the Agent the forms described in one of the following
two clauses:

            (a) Two fully completed and duly executed United States Internal
      Revenue Service Form 1001 or 4224 or any successor form, as the case may
      be, certifying that such Lender is entitled to receive payments of the
      Credit Obligations payable to it without deduction or withholding of any
      United States federal income taxes; or

            (b) A statement, executed by such Lender under penalty of perjury,
      certifying that such Lender is not a "bank" within the meaning of Section
      881(c)(3)(A) of the Code and two fully completed and duly executed United
      States Internal Revenue Service Forms W-8 or any successor form,
      certifying that such Lender is not a "United States person" within the
      meaning of Section 7701(a)(30) of the Code.

Each Lender that delivers any form or statement pursuant to this Section 17
further undertakes to renew such forms and statements by delivering to the
Company and the Agent any updated form, successor form or other certification,
as the case may be, on or before the date that any form or statement previously
delivered pursuant to this Section 17 expires or becomes obsolete or after the
occurrence of any event requiring a change in such most recent form or
statement. If at any time the Company and the Agent have not received all forms
and statements (including any renewals thereof) required to be provided by any
Lender pursuant to this Section 17, Section 3.4 shall not apply with respect to
any amount of United States federal income taxes required to be withheld from
payments of the Credit Obligations to such Lender.

18. Notices. Except as otherwise specified in this Agreement or any other Credit
Document, any notice required to be given pursuant to this Agreement or any
other Credit Document shall be given in writing. Any notice, consent, approval,
demand or other communication in connection with this Agreement or any other
Credit Document shall be deemed to be given if given in writing (including
telex, telecopy or similar teletransmission) addressed as provided below (or to
the addressee at such other address as the addressee shall have specified by
notice actually received by the addressor), and if either (a) actually delivered
in fully legible form to such address (evidenced in the case of a telex by
receipt of the correct answerback) or (b) in the case of a letter, unless actual
receipt of the notice is required by any

                                       67
<PAGE>
Credit Document five (5) days shall have elapsed after the same shall have been

            (a) Except as provided below, without the written consent of the
      Lenders owning at least a majority of the Percentage Interests
      (disregarding the Percentage Interest of any Nonperforming Lender so long
      as such Lender is treated equally with the other Lenders with respect to
      any actions enumerated below), no written modification of, amendment to,
      consent with respect to, waiver of compliance with or waiver of a Default
      under, any of the Credit Documents (other than any Hedge Agreements from
      time to time in effect) shall be made.

            (b) Without the written consent of such Lenders as own one hundred
      percent (100%) of the Percentage Interests (disregarding the Percentage
      Interest of any Nonperforming Lender so long as such Lender is treated

      below):

                  (i) None of the conditions specified in Section 9 shall be

            the Agent may release particular items of Credit Security or
            particular Guarantors in dispositions permitted by Section 10.12, as
            modified by amendments thereto approved by the Required Lenders, and
            may release all Credit Security pursuant to Section 20.1 upon
            payment in full of the Credit Obligations and termination of the
            Commitments).

                  (iii) No incurrence or existence of any Lien on all or
            substantially all of the Credit Security shall be permitted (other
            than Liens securing the Credit Obligations).

            the definition of "Required Lenders" shall be made.

            (c) Without the written consent of each Lender that is directly
      affected thereby, as well as such Lenders as own at least a majority of
      the Percentage Interests (disregarding the Percentage Interest of any
      Nonperforming Lender so long as such Lender is treated equally with the
      other Lenders with respect to any actions enumerated below):

<PAGE>
                  (i) No reduction shall be made in (A) the amount of principal
            of the Loan owing to such Lender or participated to such Lender, (B)
            the interest rate on the portion of the Loan owing to such Lender or
            (C) the commitment fees owing to such Lender with respect to the
            credit facility provided herein (other than amendments and waivers
            approved by the Required Lenders that modify defined terms used in
            calculating the Applicable Rate or that waive an increase in the
            Applicable Rate as a result of an Event of Default).

                  (ii) No change shall be made in the stated, scheduled time of
            payment of any portion of the Loan owing to such Lender or interest
            thereon or fees relating to any of the foregoing payable to such
            Lender and no waiver shall be made of any Default under Section
            12.1.1 with respect to such Lender (other than amendments and
            waivers approved by the Required Lenders that modify defined terms
            used in calculating the Applicable Rate).

                  (iii) No increase shall be made in the amount, or extension of
            the term, of the stated Commitments of such Lender beyond that
            provided for under Section 2.

            (d) Without the written consent of the Agent, no amendment or
      modification of any Credit Document shall affect the rights or duties of
      the Agent under the Credit Documents.

                  19.1.2. Course of Dealing; No Implied Waivers. No course of
            dealing between any Lender or the Agent, on one hand, and the
            Company or any other Obligor, on the other hand, shall operate as a
            waiver of any of the Lenders' or the Agent's rights under this
            Agreement or any other Credit Document or with respect to the Credit
            Obligations. In particular, no delay or omission on the part of any
            Lender or the Agent in exercising any right under this Agreement or
            any other Credit Document or with respect to the Credit Obligations
            shall operate as a waiver of such right or any other right hereunder
            or thereunder. A waiver on any one occasion shall not be construed
            as a bar to or waiver of any right or remedy on any future occasion.
            No waiver, consent or amendment with respect to this Agreement or
            any other Credit Document shall be binding unless it is in writing
            and signed by the Agent or the Required Lenders.

20. General Provisions.

20.1. Defeasance. When all Credit Obligations have been paid, performed and
reasonably determined by the Agent to have been indefeasibly discharged in full,
and if at the time no Lender continues to be committed to extend any credit to
the Company hereunder or under any other Credit Document, this Agreement and the
other Credit Documents shall terminate and, at the Company's written request,
accompanied by such certificates and other items as the Agent shall reasonably
deem necessary, the Credit Security shall revert to the Obligors and the right,
title and interest of the Agent and the Lenders therein shall terminate.
Thereupon, on the Obligors' demand and at their cost and expense, the Agent
shall execute proper instruments, acknowledging satisfaction of and discharging
this Agreement and the other Credit Documents, and shall redeliver to the
Obligors any Credit Security then in its possession; provided, however, that
Sections 3.4 (for ninety (90) days after termination of this Agreement), 13,
14.7.7, 14.10, 12 and 20 shall survive the termination of this Agreement.

20.2. No Strict Construction. The parties have participated jointly in the
negotiation and drafting of this Agreement and the other Credit Documents with
counsel sophisticated in financing transactions. In the event an ambiguity or
question of intent or interpretation arises, this Agreement and the other Credit
Documents shall be construed as if drafted jointly by the parties and no
presumption or burden of proof shall arise favoring or disfavoring any party by
virtue of the authorship of any provisions of this Agreement and the other
Credit Documents.

20.3. Certain Obligor Acknowledgments. Each of the Company and the other
Obligors acknowledges that:

            (a) it has been advised by counsel in the negotiation, execution and
      delivery of this Agreement and the other Credit Documents;

            (b) neither the Agent nor any Lender has any fiduciary relationship
      with or duty to the Obligors arising out of or in connection with this
      Agreement or any other Credit Document, and the relationship between the
      Agent and Lenders, on one hand, and the Obligors, on the other hand, in
      connection herewith or therewith is solely that of debtor and creditor;
      and

            (c) no joint venture is created hereby or by the other Credit
      Documents or otherwise exists by virtue of the transactions contemplated
      hereby or thereby among the Obligors and the Lenders.

20.4. Venue; Service of Process; Certain Waivers. Each of the Company, the other
Obligors, the Agent and the Lenders:

            (a) Irrevocably submits to the nonexclusive jurisdiction of the
      state courts of The Commonwealth of Massachusetts and to the nonexclusive
      jurisdiction of the United States District Court for the District of
      Massachusetts for the purpose of any suit, action or other proceeding
      arising out of or based upon this Agreement or any other Credit Document
      or the subject matter hereof or thereof;

            (b) Waives to the extent not prohibited by applicable law that
      cannot be waived, and agrees not to assert, by way of motion, as a defense
      or otherwise, in any such proceeding brought in any of the above-named
      courts, any claim that it is not subject personally to the jurisdiction of
      such court, that its property is exempt or immune from attachment or
      execution, that such proceeding is brought in an inconvenient forum, that
      the venue of such proceeding is improper, or that this Agreement or any
      other Credit Document, or the subject matter hereof or thereof, may not be
      enforced in or by such court;

            (c) Consents to service of process in any such proceeding in any
      manner at the time permitted by Chapter 223A of the General Laws of The
      Commonwealth of Massachusetts and agrees that service of process by
      registered or certified mail, return receipt requested, at its address
      specified in or pursuant to Section 18 is reasonably calculated to give
      actual notice; and

            (d) Waives to the extent not prohibited by applicable law that
      cannot be waived any right it may have to claim or recover in any such
      proceeding any special, exemplary, punitive or consequential damages.

20.5. WAIVER OF JURY TRIAL. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT
CANNOT BE WAIVED, EACH OF THE COMPANY, THE OTHER OBLIGORS, THE AGENT AND THE
LENDERS WAIVES, AND COVENANTS THAT IT SHALL NOT ASSERT (WHETHER AS PLAINTIFF,
DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF
ANY ISSUE, CLAIM OR PROCEEDING ARISING OUT OF THIS AGREEMENT OR ANY OTHER CREDIT
DOCUMENT OR THE SUBJECT MATTER HEREOF OR THEREOF OR ANY CREDIT OBLIGATION OR IN
ANY WAY CONNECTED WITH THE DEALINGS OF THE LENDERS, THE AGENT, THE COMPANY OR
ANY OTHER OBLIGOR IN CONNECTION WITH ANY OF THE ABOVE, IN EACH CASE WHETHER NOW
EXISTING OR HEREAFTER ARISING AND WHETHER IN CONTRACT, TORT OR OTHERWISE. Each
of the Company and the other Obligors acknowledges that it has been informed by
the Agent that the foregoing sentence constitutes a material inducement upon
which each of the Lenders has relied and will rely in entering into this
Agreement and any other Credit Document. Any Lender, the Agent, the Company or
any other Obligor may file an original counterpart or a copy of this

                                       70
<PAGE>
Agreement with any court as written evidence of the consent of the Company, the
other Obligors, the Agent and the Lenders to the waiver of their rights to trial
by jury.

20.6. Interpretation; Governing Law; etc. Time is (and shall be) of the essence
in this Agreement and the other Credit Documents. All covenants, agreements,
representations and warranties made in this Agreement or any other Credit
Document or in certificates delivered pursuant hereto or thereto shall be deemed
to have been relied on by each Lender, notwithstanding any investigation made by
any Lender on its behalf, and shall survive the execution and delivery to the
Lenders hereof and thereof. The invalidity or unenforceability of any provision
hereof shall not affect the validity or enforceability of any other provision
hereof, and any invalid or unenforceable provision shall be modified so as to be
enforced to the maximum extent of its validity or enforceability. The headings
in this Agreement are for convenience of reference only and shall not limit or
otherwise affect the meaning hereof. This Agreement and the other Credit
Documents constitute the entire understanding of the parties with respect to the
subject matter hereof and thereof and supersede all prior and contemporaneous
understandings and agreements, whether written or oral. This Agreement may be
executed in any number of counterparts which together shall constitute one
instrument. This Agreement shall be governed by and construed in accordance with
the laws (other than the conflict of laws rules) of The Commonwealth of
Massachusetts.
