     to effect the conversion of the Term C Loan Amount pursuant to the New
     Parent Conversion Right and the New WGSI Conversion Right, on a fully

     (including cash) receivable thereupon by a shareholder include securities
     and property of a corporation other than the successor or purchasing
     entity, as the case may be, in such consolidation, merger, sale or

     in this Section 2.17.4, the Term C Loan Amount shall thereafter evidence
     the right to receive, at the adjusted New Conversion Price, that number of
     shares of Common Stock (calculated to the nearest one-hundredth) obtained
     by dividing (i) the product of the aggregate number of shares of Common

          (c)  Extraordinary Dividends and Distributions  In case Parent or WGSI
               -----------------------------------------
     as the case may be, at any time or from time to time after the date hereof
     shall declare, order, pay or make a dividend or other distribution
     (including, without limitation, any distribution of other or additional
     stock or other securities or property or options by way of dividend or
     spin-off, reclassification, recapitalization or similar corporate
     rearrangement) on Common Stock other than (a) a dividend payable in

     dividend, the New Conversion Price in effect immediately prior to the close
     of business on the record date fixed for the determination of holders of
     any class of securities entitled to receive such dividend shall be reduced,
     effective as of the close of business on such record date, to a price
     determined by multiplying such New Conversion Price by a fraction

               effect on such record date or, if the Common Stock trades on an
               ex-dividend basis, on the date prior to the commencement of ex-
               dividend trading, less the Fair Value of such dividend or
               distribution applicable to one share of Common Stock, and

     Shares of Common Stock (as set forth in the instrument relating thereto,
     without regard to any provisions contained therein for a subsequent
     adjustment of such number) issuable upon the exercise of such Options or,
     in the case of Convertible Securities and Options therefor, the conversion

     business on such record date (or, if the Common Stock trades on an ex-
     dividend basis, on the date prior to the commencement of ex-dividend
     trading), provided that such Additional Shares of Common Stock shall not be

               shall be made upon the subsequent issue or sale of Convertible
               Securities or shares of Common Stock upon the exercise of such
               Options or the conversion or exchange of such Convertible
               Securities;

               in the consideration payable to Parent or WGSI, as the case may
               be, or decrease in the number of Additional Shares of Common
               Stock issuable, upon the exercise, conversion or exchange thereof
               (by change of rate or otherwise), the New Conversion Price
               computed upon the original issue, sale, grant or assumption
               thereof (or upon the occurrence of the record date, or date prior
               to the commencement of ex-dividend trading, as the case may be,
               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, which are
               outstanding at such time;

               (iii)  upon the expiration (or purchase by Parent or WGSI, as the
               case may be, and cancellation or retirement) of any such Options
               which shall not have been exercised or the expiration of any
               rights of conversion or exchange under any such Convertible
               Securities which (or purchase by Parent or WGSI, as the case may
               be, and cancellation or retirement of any such Convertible
               Securities the rights of conversion or exchange under which)
               shall not have been exercised, the New Conversion Price computed
               upon the original issue, sale, grant or assumption thereof (or
               upon the occurrence of the record date, or date prior to the
               commencement of ex-dividend trading, as the case may be, with
               respect thereto), and any subsequent adjustments based thereon,
               shall, upon such expiration (or such cancellation or retirement,
               as the case may be), be recomputed as if:

                      Securities, the only Additional Shares of Common Stock

                      actually issued or sold upon the exercise of such Options
                      or the conversion or exchange of such Convertible
                      Securities and the consideration received therefor was the
                      consideration actually received by Parent or WGSI, as the
                      case may be, for the issue, sale, grant or assumption of
                      all such Options, whether or not exercised, plus the
                      consideration actually received by Parent or WGSI, as the
                      case may be, upon such exercise, or for the issue or sale
                      of all such Convertible Securities which were actually
                      converted or exchanged, plus the additional consideration,
                      if any, actually received by Parent or WGSI, as the case
                      may be, upon such conversion or exchange, and

                      (B) in the case of Options for Convertible Securities,
                      only the Convertible Securities, if any, actually issued
                      or sold upon the exercise of such Options were issued at
                      the time of the issue or sale, grant or assumption of such
                      Options, and the consideration received by Parent or WGSI,
                      as the case may be, for the Additional Shares of Common
                      Stock deemed to have then been issued was the
                      consideration actually received by Parent or WGSI, as the
                      case may be, for the issue, sale, grant or assumption of
                      all such Options, whether or not exercised, plus the
                      consideration deemed to have been received by Parent or
                      WGSI, as the case may be (pursuant to Section 2.17.4(f))
                                                            -----------------
                      upon the issue or sale of such Convertible Securities with
                      respect to which such Options were actually exercised;

               (iv)   no readjustment pursuant to subsection (ii) or (iii) above
               shall have the effect of increasing the New Conversion Price by
               an amount in excess of the amount of the adjustment thereof
               originally made in respect of the issue, sale, grant or
               assumption of such Options or Convertible Securities; and

               (v)    in the case of any such Options which expire by their
               terms not more than 30 days after the date of issue, sale, grant
               or assumption thereof, no adjustment of the New Conversion Price
               shall be made until the expiration or exercise of all such
               Options, whereupon such adjustment shall be made in the manner
               provided in subsection (iii) above.

          (e)  Treatment of Stock Dividends, Stock Splits, Etc  In case Parent
               -----------------------------------------------
     or WGSI, as the case may be, at any time or from time to time after the
     date hereof shall declare or pay any dividend on Common Stock payable in
     Common Stock, or shall effect a subdivision of the outstanding shares of
     Common Stock into a greater number of shares of Common Stock (by
     reclassification or otherwise than by payment of a dividend or dividend in
     shares of Common Stock), then, and in each such case, Additional Shares of
     Common Stock shall be deemed to have been issued (i) in the case of any
     such dividend, immediately after the close of business on the record date
     for the determination of holders

                                      -13-
<PAGE>

     of any class of securities entitled to receive such dividend, or (ii) in
     the case of any such subdivision, at the close of business on the day
     immediately prior to the day upon which such action becomes effective.

          (f)  Computation of Consideration  For the purposes of this Section
               ----------------------------                           -------
     2.17.4,
     ------

               (i)  the consideration for the issue or sale of any Additional
          Shares of Common Stock shall, irrespective of the accounting treatment
          of such consideration,

               (x)  insofar as it consists of cash, be computed at the net
               amount of cash received by Parent or WGSI, as the case may be,
               without deducting any expenses paid or incurred by Parent or
               WGSI, as the case may be, or any commissions or compensations
               paid or concessions or discounts allowed to underwriters, dealers
               or others performing similar services in connection with such
               issue or sale,

               (y)  insofar as it consists of property (including securities)
               other than cash, be computed at the Fair Value thereof at the
               time of such issue or sale, and

               (z)  in case Additional Shares of Common Stock are issued or sold
               together with other stock or securities or other assets of Parent
               or WGSI, as the case may be, for a consideration which covers
               both, be the portion of such consideration so received, computed
               as provided in clauses (i) and (ii) above, allocable to such
               Additional Shares of Common Stock, such allocation to be
               determined in the same manner that the Fair Value of property not
               consisting of cash or securities is to be determined as provided
               in the definition of 'Fair Value' herein;

               (ii) Additional Shares of Common Stock deemed to have been issued
          pursuant to Section 2.17.4, relating to Options and Convertible
                      --------------
          Securities, shall be deemed to have been issued for a consideration
          per share determined by dividing

                    (x) the total amount, if any, received and receivable by
               Parent or WGSI, as the case may be, as consideration for the
               issue, sale, grant or assumption of the Options or Convertible
               Securities in question, plus the minimum aggregate amount of
               additional consideration (as set forth in the instruments
               relating thereto, without regard to any provision contained
               therein for a subsequent adjustment of such consideration to
               protect against dilution) payable to Parent or WGSI, as the case
               may be, upon the exercise in full of such Options or the
               conversion or exchange of such Convertible Securities or, in the
               case of Options for Convertible Securities, the exercise of such
               Options for Convertible Securities and the conversion or exchange
               of such Convertible Securities, in each case computing such
               consideration as provided in the foregoing subdivision (i),

                                      -14-
<PAGE>

               by

                     (y) the maximum number of shares of Common Stock (as set
               forth in the instruments relating thereto, without regard to any
               provision contained therein for a subsequent adjustment of such
               number to protect against dilution) issuable upon the exercise of
               such Options or the conversion or exchange of such Convertible
               Securities; and

               (iii) Additional Shares of Common Stock deemed to have been
          issued pursuant to this Section, relating to stock dividends, stock
          splits, etc. or to employee benefit plans, employee compensation or
          incentives of Parent or WGSI, as the case may be, or any Affiliate
          thereof or otherwise to employees of Parent or WGSI, as the case may
          be, or any Affiliate thereof (except in a public offering open to the
          public generally on the same terms as such employees) shall be deemed
          to have been issued for no consideration.

          (g) Adjustments for Combinations, Etc  In case the outstanding shares
              ---------------------------------
     of Common Stock shall be combined or consolidated, by reclassification or
     otherwise, into a lesser number of shares of Common Stock, the New
     Conversion Price in effect immediately prior to such combination or
     consolidation shall, concurrently with the effectiveness of such
     combination or consolidation, be proportionately increased.

          (h) Dilution in Case of Other Securities  In case any Other Securities
              ------------------------------------
     shall be issued or sold or shall become subject to issue or sale upon the
     conversion or exchange of any stock (or Other Securities) of Parent or
     WGSI, as the case may be, (or any issuer of Other Securities of any other
     Person) or to subscription, purchase or other acquisition pursuant to any
     Options issued or granted by Parent or WGSI, as the case may be, (or any
     such other issuer or Person) for a consideration such as to dilute, on a
     basis consistent with the standards established in the other provisions of
     this Section 2.17.4, the New Conversion Rights under this Section 2.17,
          --------------                                       ------------
     then, and in each such case, the computations, adjustments and
     readjustments provided for in this Section 2.17.4 with respect to the New
                                        --------------
     Conversion Price and the number of shares purchasable hereunder shall be
     made as nearly as possible in the manner so provided and applied to
     determine the amount of Other Securities from time to time receivable upon
     the exercise of the New Conversion Rights, so as to protect the holders of
     the Term C Loan Amount against the effect of such dilution.

          (i) De Minimis Adjustments.  If the amount of any adjustment of the
              ----------------------
     New Conversion Price per share required pursuant to this Section 2.17.4
                                                              --------------
     would be less than one tenth (1/10) of one percent (1%) of the New
     Conversion Price, such amount shall be carried forward and adjustment with
     respect thereto made at the time of and together with any subsequent
     adjustment which, together with such amount and any other amount or amounts
     so carried forward, shall aggregate a change in the New Conversion Price of
     at least one tenth (1/10) of one percent (1%) of such New Conversion Price.
     All calculations under this Section shall be made to the nearest .001 of a
     cent or to the nearest one-hundredth of a share, as the case may be.

                                      -15-
<PAGE>

          (j) Abandoned Dividend or Distribution.  If Parent or WGSI, as the
              ----------------------------------
     case may be, shall take a record of the holders of its Common Stock for the
     purpose of entitling them to receive a dividend or other distribution
     (which results in an adjustment to the New Conversion Price under the terms
     of this Agreement) and shall, thereafter, and before such dividend is paid
     or delivered to members entitled thereto, legally abandon its plan to pay
     or deliver such dividend or distribution, then any adjustment made to the
     New Conversion Price and number of shares of Common Stock into which Term C
     Loan Amount is convertible by reason of the taking of such record shall be
     reversed, and any subsequent adjustments, based thereon, shall be
     recomputed.

          (k) Other Dilutive Events  In case any event shall occur as to which
              ---------------------
     the provisions of this Section hereof are not strictly applicable or if
     strictly applicable would not fairly protect the conversion rights of the
     holders of this Agreement in accordance with the essential intent and
     principles of such Sections, then, in each such case, the Board of
     Directors of Parent or WGSI, as the case may be, shall make an adjustment
     in the application of such provisions, in accordance with such essential
     intent and principles, so as to preserve, without dilution, the New
     Conversion Rights in accordance with this Section 2.17.
                                               ------------

          (l) No Dilution or Impairment  Parent or WGSI, as the case may be,
              -------------------------
     shall not, by amendment of its certificate of incorporation or through any
     consolidation, merger, reorganization, transfer of assets, dissolution,
     issue or sale of securities or any other voluntary action, avoid or seek to
     avoid the observance or performance of any of the terms of this Section
                                                                     -------
     2.17, but will at all times in good faith assist in the carrying out of all
     -----
     such terms and in the taking of all such action as may be necessary or
     appropriate in order to protect the rights of the Term C Lender under this
     Section 2.17 against dilution or other impairment.  Without limiting the
     ------------
     generality of the foregoing, Parent or WGSI, as the case may be (i) shall
     take all such action as may be necessary or appropriate in order that
     Parent and WGSI, as the case may be, may validly and legally issue fully
     paid and nonassessable shares of Common Stock, free from all taxes, liens,
     security interests, encumbrances, preemptive rights and charges on the
     exercise of the New Conversion Rights, (ii) shall not take any action which
     results in any adjustment of the New Conversion Price if the total number
     of shares of Common Stock (or Other Securities) issuable after the action
     upon the exercise of the New Conversion Rights would exceed the total
     number of shares of Common Stock (or Other Securities) then authorized by
     Parent's or WGSI's, as the case may be, certificate of incorporation and
     available for the purpose of issue upon such exercise, (iii) shall not
     permit the par value of any shares of stock receivable upon exercise of the
     New Conversion Rights to exceed the amount payable therefor upon such
     exercise, and (iv)  shall not issue any capital stock of any class which is
     preferred as to dividends or as to the distribution of assets upon
     voluntary or involuntary dissolution, liquidation or winding-up, unless the
     rights of the holders thereof shall be limited to a fixed sum or percentage
     of par value or a sum determined by reference to a formula based on a
     published index of interest rates, an interest rate publicly announced by a
     financial institution or a similar indicator of interest rates in respect
     of participation in dividends and to a fixed sum or percentage of par value
     in any such distribution of assets.

hereby), the New Parent Warrant shall expire, and (ii) if the Term C Lender

the Term C Equity Documents. Such consent and waiver shall be effective only in
this specific instance and for this specific purpose and shall not permit any
further departure from the terms of the Loan Documents, all of which shall
remain in full force in effect (except as expressly set forth in this Amendment)
and are hereby ratified and confirmed.

5.   Representations and Warranties.  Each Borrower hereby represents and
warrants to the Lender Group that (a) the execution, delivery, and performance
of each Amendment Document to which it is a party, and the performance of the
Loan Agreement, as amended by this Amendment, are within its corporate or other
organizational powers, have been duly authorized by all necessary corporate
action, and are not in contravention of any law, rule, or regulation, or any
order, judgment, decree, writ, injunction, or award of any arbitrator, court, or
governmental authority, or of the terms of its charter or bylaws, or of any
contract or undertaking to which it is a party or by which any of its properties
may be bound or affected, and (b) each Amendment Document to which it is a party
and the Loan Agreement, as amended by this Amendment, constitute such Borrower's
legal, valid, and binding obligation, enforceable against such Borrower in
accordance with its terms.

6.   Further Assurances.  Borrowers shall execute and deliver all agreements,
documents, and instruments, in form and substance satisfactory to Agent, and
take all actions as Agent or any Lender may reasonably request from time to time
fully to consummate the transactions contemplated under the Amendment Documents
and the Loan Agreement, as amended by this Amendment.

7.   Miscellaneous.

     (a)  Upon the effectiveness of this Amendment, each reference in the Loan

different parties on separate counterparts, each of which, when executed and
delivered, shall be deemed to be an original, and all of which, when taken
together, shall constitute but one and the same Amendment.  Delivery of an
executed counterpart of this Amendment by telefacsimile shall be equally as
effective as delivery of a manually executed counterpart of this Amendment.  Any
party delivering an executed counterpart of this Amendment by telefacsimile also
shall deliver a

                                      -20-
