                                       11


               (i) for each such share of Common  Stock with respect to which an
          election to receive a Capital Stock Unit has been effectively made and
          not  validly  revoked  or lost,  pursuant  to  Section  3.1(d) and (g)

          the right to receive  an amount in cash (the "Per  Share  Cash  Common
          Merger Consideration"), as determined in Section 3.1(c) below.

     Parent to Buyer Sub  immediately  prior to the Effective  Time and shall be

          record holder of shares of Common Stock (other than Dissenting Shares)
          will be  entitled,  with  respect to all or any  portion of his shares
          other than Management Roll Shares,  to make an unconditional  election
          (a  "Non-Cash  Election")  on or prior to the Closing  Date to receive
          Capital Stock Units  pursuant to Section  3.1(b)(i),  on the basis set
          forth in this Section 3.1.

               (ii)  Any  Form  of  Election  submitted  to  the  Company  by  a
          stockholder  may be revoked  by such  stockholder  by  written  notice


                                       12


          received by the  Company  prior to 5:00 p.m.,  New York City time,  on

          automatically be revoked if the transactions  contemplated herein have
          been abandoned.

               (iii) If the  Company  determines  that any  election  to receive
          Capital  Stock Units was not  properly  made with respect to shares of
          Common  Stock,  such shares  shall be treated by the Company as shares
          which were not Electing  Shares at the Effective Time, and such shares
          shall be  converted  at the  Effective  Time into the right to receive
          cash pursuant to Section  3.1(b)(ii).  The Company shall also make all
          computations  as to the allocation and the proration  contemplated  by
          Section  3.1(e),  and any such  computation  shall be  conclusive  and
          binding on the holders of shares of Common Stock.

          (e)  Notwithstanding  anything in this Agreement to the contrary,  the
     aggregate  number of shares of Common Stock to be converted  into the right
     to receive  Capital Stock Units at the Effective  Time shall not exceed the
     quotient of (1) the Aggregate Stock Consideration Value, divided by (2) the
     Per  Share  Cash  Common  Merger   Consideration  (the  "Non-Cash  Election
     Number").

               (i) If  the  number  of  Electing  Shares  exceeds  the  Non-Cash
          Election Number,  then each Electing Share shall be converted into the
          right to receive  Capital  Stock Units or receive  cash in  accordance
          with the terms of Section 3.1(b) in the following manner:

                    (A) a proration  factor (the  "Non-Cash  Proration  Factor")
               shall be determined by dividing the Non-Cash  Election  Number by
               the total number of Electing Shares;

                    (B) the number of Electing  Shares  covered by each Non-Cash
               Election to be converted into the right to receive  Capital Stock
               Units shall be determined by multiplying  the Non-Cash  Proration
               Factor by the total  number of  Electing  Shares  covered by such
               Non-Cash Election rounded down to the nearest whole number; and

                    (C) all Electing  Shares,  other than those shares converted
               into the right to receive  Capital Stock Units in accordance with
               Section  3.1(e)(i)(B),  shall  be  converted  into  the  right to
               receive cash (on a consistent  basis among  stockholders who made
               the  election  referred  to in  Section  3.1(b)(i),  pro  rata in
               accordance  with the  number of shares as to which they made such
               election)  as  if  such  shares  were  not  Electing   Shares  in
               accordance with the terms of Section 3.1(b)(ii).

               (ii)  If  the  Number  of  Electing   Shares  is  less  than  the
          Non-Election Number, then:

                    (A) all Electing Shares shall be converted into the right to
               receive  Capital  Stock  Units in  accordance  with the  terms of
               Section 3.1(b)(i); and

                                       13


                    (B) at the option of VEP, by written notice  delivered on or
               prior to 5:00 p.m., New York City time, on Thursday,  March,  25,
               2004,  a number of the  shares of Common  Stock held by VEP up to
               (1) the Non-Cash Election Number minus (2) the number of Electing
               Shares,  shall be  converted  into the right to  receive  Capital
               Stock Units in accordance with Section 3.1(b)(i) (on a consistent
               basis among  stockholders  who held shares of Common  Stock as to
               which  they did not  make the  election  referred  to in  Section
               3.1(b)(i), pro rata in accordance with the number of shares as to
               which they did not make such election).

          (f) Each share of Preferred Stock outstanding immediately prior to the
     Effective  Time  shall be  converted  into the  right to  receive  from the
     Surviving  Corporation an amount in cash equal to the aggregate liquidation
     preference of Preferred Stock plus all accrued and unpaid dividends thereon
     through and  including  the Closing Date (the "Per Share  Preferred  Merger
     Consideration").  The aggregate Per Share  Preferred  Merger  Consideration
     shall be paid by the Surviving  Corporation pursuant to this Section 3.1(g)
     by wire transfer of immediately available funds to an account (or accounts)
     specified  to Buyer  Parent at least two days  prior to the  Closing by the
     Company on behalf of each holder of Preferred Stock.

          (g) As soon as  reasonably  practicable  after  the date  hereof,  the
     Company  shall mail to each holder of record,  as of the date hereof,  of a
     certificate  representing  any  Common  Stock or  Preferred  Stock  (each a
     "Certificate"  and,  collectively,  the  "Certificates")  (i) a  letter  of
     transmittal in a form reasonably  satisfactory to the parties hereto (which
     shall contain customary  representations  and warranties as to title, shall
     specify that delivery shall be effected,  and risk of loss and title to the
     Certificates  shall pass, only upon proper delivery of the  Certificates to
     the Company and shall contain an  indemnification  by the  stockholder  for
     such  stockholder's  pro rata share (in the same proportion as such holders
     would have been  entitled  to receive the  aggregate  Per Share Cash Common
     Merger   Consideration   and  the  aggregate  Per  Share  Preferred  Merger
     Consideration  to be issued  and paid  pursuant  to Section  3.1(b)  hereof
     (without  regard  to  the  Management  Roll))  of any  Transaction  Related
     Expenses not paid on or prior to the Closing Date),  (ii)  instructions for
     use in effecting the surrender of the  Certificates  for payment  therefor,
     and (iii) to each holder of a Certificate  representing any Common Stock, a
     form of election in a form  reasonably  satisfactory  to the parties hereto
     (the  "Form  of  Election"),  which  shall  be  used by  each  holder  of a
     Certificate  of Common  Stock who  wishes to elect  (with  respect  to such
     holder's  shares of Common Stock) to receive  Capital Stock Units (and cash
     in lieu of  fractional  shares of  Capital  Stock  Units),  subject  to the
     provisions  of Section  3.1(e)  hereof.  Upon  surrender  to the  Surviving
     Corporation of a Certificate, together with such letter of transmittal duly
     executed and completed in accordance with the instructions  thereto and any
     other required documents,  the holder of such Certificate shall be entitled
     to receive for each of the shares  represented by such  Certificate the Per
     Share Cash Common Merger  Consideration,  the Capital Stock Units (and cash
     in lieu of  fractional  shares  of  Capital  Stock  Units) or the Per Share
     Preferred Merger Consideration,  as the case may be, which shall be paid or
     delivered by the  Surviving  Corporation  promptly  following the Effective
     Time pursuant to Section 3.1(b) or (f), as applicable, and such Certificate
     shall be  cancelled.  The Company shall  establish a procedure  pursuant to
     which  transmittal  letters are made available to  stockholders  as soon as
     reasonably practicable after the date hereof for completion and delivery to
     the Company, so that Persons entitled to receive payment under this Section


                                       14


     3.1 can  receive  payment  for  their  shares on the  Closing  Date by wire
     transfer.  Until so surrendered,  such Certificates  shall represent solely
     the  right to  receive  the Per Share  Cash  Common  Merger  Consideration,
     certificates of Capital Stock Units (and cash in lieu of fractional  shares
     of Capital Stock Units) or Per Share Preferred Merger Consideration, as the
     case may be, payable or deliverable pursuant to Section 3.1(b) and (f) with
     respect to each of the shares represented thereby. Any election by a holder
     of a  Certificate  representing  Common  Stock  (other than VEP) to receive
     Capital Stock Units shall have been properly made only if the Company shall
     have received at its designated  office,  prior to 5:00 p.m., New York City
     time, on Wednesday,  March 24, 2004 a Form of Election  properly  completed
     and signed by such  holder.  Any election by VEP to receive  Capital  Stock
     Units shall have been properly made only if the Company shall have received
     at its  designated  office,  prior to 5:00  p.m.,  New York City  time,  on
     Thursday,  March 25, 2004 a Form of Election properly  completed and signed
     by VEP. Notwithstanding the foregoing, the Surviving Corporation may reduce
     the cash amount payable to any holder by the Management Loan Amount owed to
     the Company by such holder.  Upon Buyer Parent's  request the Company shall
     deliver copies of completed letters of transmittal and Forms of Election.

          (h) Each share of common stock, par value $.01 per share, of Buyer Sub
     outstanding immediately prior to the Effective Time shall be converted into
     one fully paid and nonassessable  share of common stock, par value $.01 per
     share, of the Surviving Corporation.

               (i) (i) At the Effective Time, all rights in respect of Preferred
          Stock or Common Stock or securities  convertible  into or exchangeable
          for  or   exercisable   into  Common  Stock   (collectively,   "Equity
          Securities")  shall  cease to exist,  other  than the right to receive
          cash or Capital Stock Units (and cash in lieu of fractional  shares of
          Capital  Stock  Units) as  described  in  Sections  3.1(b) and (f) and
          Section 3.2.

               (ii) No dividends or other  distributions with respect to Capital
          Stock Units with a record date after the Effective  Time shall be paid
          to the holder of any  unsurrendered  Certificate  for shares of Common
          Stock with  respect  to the  Capital  Stock  Units to be  received  in
          respect thereof and no cash payment in lieu of fractional  shares of a
          Capital  Stock  Unit  shall be paid to any  such  holder  pursuant  to
          Section  3.1(i)(iii)  until  the  surrender  of  such  Certificate  in
          accordance with this Article III.  Subject to the effect of applicable
          Laws, following surrender of any such Certificate, there shall be paid
          to the holder of the Certificate  representing  whole shares of Common
          Stock issued in connection  therewith,  without  interest,  (i) at the
          time of such  surrender  the  amount of any cash  payable in lieu of a
          fractional  share of  Capital  Stock  Units to which  such  holder  is
          entitled pursuant to Section 3.1(i)(iii) and the proportionate  amount
          of  dividends  or other  distributions  with a record  date  after the
          Effective Time  theretofore  paid with respect to such whole shares of
          Common  Stock,   and  (ii)  at  the  appropriate   payment  date,  the
          proportionate amount of dividends or other distributions with a record
          date  after  the  Effective  Time but  prior to such  surrender  and a
          payment date subsequent to such surrender payable with respect to such
          whole shares of Common Stock.

               (iii) No certificates or scrip representing  fractional shares of
          a Capital Stock Unit shall be issued in connection herewith,  and such
          fractional  share interests will not entitle the owner thereof to vote


                                       15


          or to any  rights of a  stockholder  of Buyer  Parent or the  Company.
          Notwithstanding any other provision of this Agreement, no certificates
          or scrip  representing  fractional shares of Capital Stock Units shall
          be issued upon the  surrender  for exchange of  Certificates  and such
          fractional  shares  shall not entitle the owner  thereof to vote or to
          any other  rights of a holder of  Capital  Stock  Units.  Each  record
          holder of shares of Common Stock  exchanged  pursuant hereto who would
          otherwise  have been entitled to receive a fraction of a Capital Stock
          Unit (after  taking into account all shares of Common Stock  delivered
          by such  holder)  shall  receive,  in  lieu  thereof,  a cash  payment
          (without interest) in lieu of such fractional share.

               (j) Simultaneously  with the Closing,  the Surviving  Corporation
          shall  repay,  or cause  to be  repaid,  on  behalf  of the  Surviving
          Corporation and the Company Subsidiaries, the Outstanding Debt (except
          for  amounts  outstanding  pursuant  to Items  1, 2 and 5 of  Schedule
          4.15(a)(i))  by wire  transfer of  immediately  available  funds to be
          provided at the  Closing by Buyer  Parent or Buyer Sub, as directed by
          the  holders  of such  Outstanding  Debt,  and the  Company  shall use
          commercially  reasonable  efforts  to  deliver  to  Buyer  Parent  all
          appropriate  payoff letters and to make  arrangements to deliver UCC-3
          termination statements or similar documents evidencing the termination
          of all liens,  security  interests,  mortgages and other  Encumbrances
          held by the lenders under such Outstanding Debt.

               (k) Simultaneously  with the Closing,  the Surviving  Corporation
          shall  pay,  or  cause to be  paid,  on  behalf  of the  Company,  the
          Transaction Related Expenses by wire transfer of immediately available
          funds as directed by the Company.

     Section 3.2  Options.  Effective  as of the  Effective  Time,  each Option,
whether or not then  exercisable  or  vested,  shall,  immediately  prior to the
Effective Time, be cancelled and, in  consideration  of such  cancellation,  the
holder of such  Option  shall be entitled  to receive  payment by the  Surviving
Corporation  (subject to the Surviving  Corporation  withholding  from each such
holder a portion of such amount for any applicable withholding,  excise or other
applicable Tax) of an amount in cash equal to the product of (a) the excess,  if
any, of the Per Share Cash Common Merger  Consideration  over the exercise price
of such Option  multiplied by (b) the number of shares subject  thereto  without
regard to whether previously vested. Notwithstanding anything to the contrary in
this  Agreement,  to the extent that the  exchange of cash for Options held by a
holder  would  subject  such holder to an excise tax pursuant to Section 4999 of
the Code,  such  Options  shall not be exchanged  for cash unless the  requisite
approval of the stockholders of the Company  pursuant to Section  280G(b)(5)(ii)
of the  Code is  obtained  with  respect  to such  exchange  for  cash.  If such
stockholder  approval is not obtained,  then such Options shall not be exchanged
for cash as  provided  in the first  sentence  of this  Section  3.2,  but shall
instead be  converted/adjusted  in accordance  with the terms of the  applicable
Option  Plan  and any  applicable  award  agreement.  Payment  by the  Surviving
Corporation in  consideration of cancellation of the Option shall be made at the
Closing by wire transfer of  immediately  available  funds to an account that is
specified  at least two days prior to the  Closing  by the  Company on behalf of
each holder of such Options.  Buyer Parent shall cause the Surviving Corporation
to make timely payment to the appropriate taxing authority or authorities of any
amounts  withheld from payment to the holders of Options under this Section 3.2.
Prior  to  (but  effective  at)  the  Effective  Time,  the  Company  shall  use
commercially  reasonable  efforts to (i) obtain any consents from all holders of
Options  and (ii) make any  amendments  to the terms of the Option  Plans or any
applicable  award agreements that, in the case of either clause (i) or (ii), are


                                       16


necessary to give effect to the  transactions  contemplated  by this Section 3.2
and to assure that, as of the Effective  Time, the Option Plans shall  terminate
and all rights  under any  provision of any other plan,  program or  arrangement
providing  for the  issuance  or grant of any other  interest  in respect of the
capital stock of the Company or any Company  Subsidiary shall be cancelled.  For
purposes  of the  preceding  sentence,  commercially  reasonable  efforts  shall
include  (x)  accelerating  the  date  of  vesting  and  exercisability  of  any
unexercised  and  unexpired  portion of each Option to a date  specified  by the
Board of Directors of the Company prior to the Closing Date and (y)  terminating
each Option as of the Effective Date,  provided that notice of such  termination
is given to the holder of the Option at least 10 days prior to the Closing  Date
and the holder of the Option  shall  have the right to  exercise  so much of the
Option as is then vested and exercisable during said 10-day period, including if
the Option becomes exercisable due to acceleration of exercisability as provided
in clause (x).  The  Company  shall  provide  notice to each holder of an Option
which includes an acknowledgement that, among other things, upon the cash-out of
the Option as provided for in this  Section 3.2,  such Option shall be cancelled
and the former  holders of such Option shall have no further rights with respect
to such Option.

     Section 3.3 Closing of the Company  Transfer  Books. At the Effective Time,
the stock  transfer  books of the  Company  shall be closed and no  transfer  of
Equity  Securities  shall  thereafter  be made.  If, after the  Effective  Time,
certificates  previously  representing  Equity  Securities  are presented to the
Surviving  Corporation,  they shall be canceled and exchanged for the applicable
amount of Per Share Cash  Common  Merger  Consideration  or Per Share  Preferred
Merger  Consideration or the applicable  number of Capital Stock Units (and cash
in lieu of fractional shares of Capital Stock Units) as provided in Section 3.1.

     Section 3.4 Dissenting Shares.  Notwithstanding  anything in this Agreement
to the contrary,  shares of Common Stock  outstanding  immediately  prior to the
Effective  Time and held by a holder who has not voted in favor of the Merger or
consented  thereto in writing and who has demanded  appraisal for such shares in
accordance  with the DGCL, if the DGCL  provides for  appraisal  rights for such
shares in the Merger ("Dissenting Shares"),  shall not be converted into a right
to receive the Per Share Cash Common Merger Consideration or Capital Stock Units
(and cash in lieu of fractional  shares of Capital Stock Units),  but shall have
the rights set forth in Section  262 of the DGCL (or any  successor  provision),
unless such holder fails to perfect or withdraws or otherwise loses his right to
appraisal.  If,  after the  Effective  Time,  such  holder  fails to  perfect or
withdraws  or loses his right to  appraisal,  such  Dissenting  Shares  shall be
treated as if they had been  converted as of the Effective  Time into a right to
receive  the  consideration,  if any,  to which  the  holder  of such  shares is
entitled  as  provided  in Section  3.1 hereof  without  interest  or  dividends
thereon.  The  Company  shall give Buyer  Parent  prompt  notice of any  demands
received by the Company for appraisal of shares of Common Stock,  and,  prior to
the  Effective  Time,  Buyer Parent shall have the right to  participate  in all
negotiations  and  proceedings  with  respect  to  such  demands.  Prior  to the
Effective  Time, the Company shall not, except with the prior written consent of
Buyer  Parent,  make any payment  with respect to, or settle or offer to settle,
any such demands.


                                       17

increase in the insurance rates of the Company or any Company Subsidiary;  (iii)

terminate or lapse by reason of the transactions contemplated by this Agreement,
in each case, except where such non-payment, increase, cancellation, termination

vacation,  sick leave, maternity leave, military service,  lay-off,  retirement,

Employee Arrangements are sponsored or maintained by the Company and the Company
Subsidiaries and the Buyer Parent shall indemnify VEP and all other stockholders
of the  Company  against  any and all losses  arising  out of or related to such
liabilities and obligations under the Benefit Plans and Employee Arrangements in
respect of current or former  non-U.S.  Company Group  Employees,  directors and
independent contractors.

     (f) Buyer Parent shall not, within ninety (90) days after the Closing Date,
effectuate  a "plant  closing"  or "mass  layoff" as those  terms are defined in
WARN, affecting in whole or in part any site of employment,  facility, operating
unit or Company Group Employee  without  complying with the notice  requirements
and other  provisions  of WARN which could cause any liability to the Company or
any of the Company Subsidiaries with respect to the Company Group Employees.

     Section 6.8 "As Is" Condition. Buyer Parent agrees that it shall accept the
Company and the Company  Subsidiaries  in an "As Is" "Where Is" condition at the
Effective Time, subject to the representations  and warranties  contained herein
and in the Transaction Documents.  THE COMPANY MAKES NO WARRANTY WITH RESPECT TO

     Section 10.6 Specific Performance.  The parties hereto agree that if any of
the  provisions of this  Agreement  were not performed in accordance  with their
specific terms or were otherwise  breached,  irreparable  damage would occur, no
adequate  remedy at law would exist and damages would be difficult to determine,
and that the parties  shall be entitled  to  specific  performance  of the terms
hereof, in addition to any other remedy at law or equity.



                                       51


     Section  10.7  Publicity.   None  of  the  parties  and  their   respective
representatives  shall  issue any news  release or make any public  announcement
concerning this Agreement or any of the transactions contemplated hereby without
the advance approval thereof by Buyer Parent and the Company; provided, however,
that any party may make any public disclosure that it reasonably believes,  upon
advice of its outside counsel, is required by applicable Laws, in which case the
disclosing party shall use its reasonable best efforts to advise the other party
or parties of such disclosure as soon as practicable and, in any event, at least
concurrently with making such disclosure.  Subject to the prior sentence,  Buyer
Parent and the Company shall  cooperate with each other in the  development  and
distribution of all news releases and other public announcements with respect to
this Agreement or any of the transactions contemplated hereby.

     Section 10.8 Alternative Dispute Resolution.  The parties or relevant third
party beneficiaries,  as the case may be, shall attempt in good faith to resolve
any  dispute  arising  out  of  or  relating  to  this  Agreement   promptly  by
negotiations  between  executives who have authority to settle the  controversy.
Any Person may give the other relevant Persons written notice of any dispute not
resolved  in the  normal  course of  business.  Within  twenty  (20) days  after
delivery of said  notice,  executives  of all relevant  Persons  shall meet at a
mutually  acceptable time and place,  and thereafter as often as they reasonably
deem necessary,  to exchange relevant  information and to attempt to resolve the
dispute.  If the  matter  has not been  resolved  within  sixty (60) days of the
disputing  Person's  original  notice,  or if the relevant  Persons fail to meet
within  twenty (20) days,  any party or affected  third  party  beneficiary  may
initiate legal  proceedings to resolve the  controversy or claim.  If a Person's
negotiator  intends  to be  accompanied  at a meeting  by an  attorney  or is an
attorney,  the other negotiators shall be given at least three (3) working days'
notice of such intention and may be accompanied by an attorney. All negotiations
pursuant to this clause are  confidential and shall be treated as compromise and
settlement  negotiations for purposes of the Federal Rules of Evidence and state
rules of evidence.

     Section 10.9  Governing  Law;  Submission to  Jurisdiction;  Waivers.  This
Agreement  and each  other  Transaction  Document  shall  be  governed  by,  and
construed in  accordance  with,  the Laws of the State of New York.  Each of the
parties  agrees that if any dispute is not resolved by pursuant to Section 10.8,
such  dispute  shall be  resolved  only in the  Courts  of the State of New York
sitting in the County of New York or the United  States  District  Court for the
Southern  District of New York and the appellate  courts having  jurisdiction of
appeals in such courts. In that context,  and without limiting the generality of
the foregoing,  each of the parties  irrevocably and unconditionally (a) submits
for itself and its property in any Action relating to the Transaction Documents,
or for recognition and  enforcement of any judgment in respect  thereof,  to the
jurisdiction of the Courts of the State of New York sitting in the County of New
York, the court of the United States of America for the Southern District of New
York,  and  appellate  courts  having  jurisdiction  of appeals  from any of the
foregoing,  and agrees  that all claims in respect of any such  Action  shall be
heard and determined in such New York State court or, to the extent permitted by
law, in such federal  court;  (b) consents that any such Action may and shall be
brought in such courts and waives any  objection  that it may now or  thereafter
have to the venue or  jurisdiction  of any such Action in any such court or that
such  Action  was  brought in an  inconvenient  court and agrees not to plead or


                                       52


claim the same;  (c) waives  all right to trial by jury in any  Action  (whether
based on contract,  tort or otherwise)  arising out of or relating to any of the
Transaction  Documents,  or its  performance  under  or the  enforcement  of the
Transaction Documents; (d) agrees that service of process in any such Action may
be effected by mailing a copy of such process by  registered  or certified  mail
(or any substantially  similar form of mail),  postage prepaid, to such party at
its  address as  provided in Section  10.5;  and (e) agrees that  nothing in the
Transaction Documents shall affect the right to effect service of process in any
other manner permitted by the Laws of the State of New York.

     Section 10.10  Descriptive  Headings.  The descriptive  headings herein are
inserted for convenience of reference only and are not intended to be part of or
to affect the meaning or interpretation of this Agreement.

     Section 10.11 Severability. It is the desire and intent of the parties that
the provisions of this  Agreement be enforced to the fullest extent  permissible
under  the  Laws and  public  policies  applied  in each  jurisdiction  in which
enforcement  is  sought.  Accordingly,  if  any  particular  provision  of  this
Agreement  shall be  adjudicated  by a court  of  competent  jurisdiction  to be
invalid,  prohibited or unenforceable for any reason, such provision, as to such
jurisdiction,   shall  be  ineffective,   without   invalidating  the  remaining
provisions of this Agreement or affecting the validity or enforceability of this
Agreement or affecting the validity or  enforceability  of such provision in any
other jurisdiction.  Notwithstanding  the foregoing,  if such provision could be
more narrowly drawn so as not to be invalid, prohibited or unenforceable in such
jurisdiction,  it shall, as to such jurisdiction,  be so narrowly drawn, without
invalidating  the  remaining  provisions  of this  Agreement  or  affecting  the
validity or enforceability of such provision in any other jurisdiction.

     Section 10.12  Counterparts.  This Agreement may be executed in two or more
counterparts,  each of which shall be deemed to be an original, but all of which
shall constitute one and the same agreement.

     Section 10.13  Expenses.  Whether or not the  transactions  contemplated by
this  Agreement  are  consummated,  and except as otherwise  expressly set forth
herein,  all legal and other costs and expenses  incurred in connection with the
transactions  contemplated  by  this  Agreement  shall  be  paid  by the  Person
incurring such expenses.

     Section  10.14  Parties in  Interest.  This  Agreement  shall  inure to the
benefit  of  and be  binding  upon  the  parties  hereto  and  their  respective
successors and permitted assigns. Nothing in this Agreement, express or implied,
is  intended to confer  upon any Person  other than the parties  hereto or their
successors or permitted  assigns,  any rights or remedies  under or by reason of
this Agreement;  provided, however, that the foregoing shall not limit the right
of (a)  each of the  directors  and  officers  of the  Company  and the  Company
Subsidiaries  from being a direct and irrevocable third party beneficiary of the
agreement  and covenant  contained in Section 6.6 with the right to enforce such
agreement  and  covenant  as fully as if such  director  or officer  was a party
hereto or (b) VEP from being a direct and irrevocable third party beneficiary of
the  agreements  and covenants  contained in Section 6.3 as fully as if it was a
party hereto.

     Section  10.15  Interpretation.  An item arising with respect to a specific
representation  or warranty  shall be deemed to be "reflected  on" or "set forth
in" a balance  sheet or  financial  statements,  to the extent  any such  phrase
appears in such representation or warranty,  if (a) there is a reserve,  accrual
or other  similar item  underlying  a number on such balance  sheet or financial


                                       53


statements  that relates to the subject matter of such  representation  and such
subject matter is specifically identified in the notes thereto, (b) such item is
otherwise specifically set forth on the balance sheet or financial statements or
(c) such item is reflected on the balance sheet or financial  statements  and is
specifically set forth in the notes thereto.
