of  the  Partnership  (the  "Appointment"),  Stuart  S.  Richardson  is  granted
authority  to deal  with  any and all  Shares  owned  by the  Partnership.  This

authority  to vote and sell the Shares in  connection  with any merger,  sale of

to sell the shares of Common Stock of Vanguard subject to the voting agreements,

agreements also provide that any shares of Common Stock of Vanguard acquired by
persons  who have  entered  into  voting  agreements,  whether by

                           acquires  the right to vote or share in the voting of
                           any  shares of Common  Stock  other  than the  Shares

                5. Option Shares.
                 (a) Subject to  the  terms  and conditions  set  forth  herein,
                           Stockholder  hereby  grants to Parent an  irrevocable
                           option (the  "Option")  to  purchase,  in whole or in
                           part,    such    Stockholder's    Shares   and   such
                           Stockholder's New Shares at a purchase price equal to
                           the Per Share Cash  Amount (as  defined in the Merger
                           Agreement) per share; provided,  however, that if the
                           Per Share Cash Amount  under the Merger  Agreement or
                           any amendment  thereto is ever increased or if Parent
                           shall  otherwise  offer  to the  Stockholders  of the
                           Company an increased  consideration  for all of their
                           shares  (the  "Greater   Consideration"),   then  the
                           purchase  price per share  under the Option  shall be
                           increased  to equal such new Per Share Cash Amount or
                           Greater  Consideration;  and provided further that if
                           Parent  has  exercised  the  Option  within 12 months
                           prior to such  increase  in the Per Share Cash Amount
                           or Greater  Consideration,  then Parent  shall pay to
                           each  Stockholder  an amount  equal to the product of
                           the number of shares  previously  purchased from such
                           Stockholder  pursuant to the Option and the amount of
                           increase  between  the old Per Share Cash  Amount and
                           the  new   Per   Share   Cash   Amount   or   Greater
                           Consideration, as applicable.

                 (b) Parent may exercise the Option, in whole or in part, at any
                           time and from time to time,  after the first to occur
                           of (i) any event as a result of which Parent shall be
                           entitled  to receive a  termination  fee  pursuant to
                           Section 7.2(e) of the Merger  Agreement in the amount
                           of $52.5 million  pursuant to part (1) or part (2) of
                           such  Section  or in  the  amount  of  $22.5  million

                           Agreement  (the  first of such  events  to  occur,  a
                           "Purchase Event"); provided,  however, that except as
                           provided in the last  sentence of this Section  5(b),
                           the Option shall terminate and be of no further force

                           Effective Time (as defined in the Merger  Agreement),
                           (B) 12 months and one day after the  occurrence  of a

                           Notwithstanding the termination of the Option, Parent
                           shall be entitled  to exercise  the Option or receive
                           the  Cash  Payment  Amount  if it has  given  written
                           notice  of its  intent  to  exercise  the  Option  or
                           receive the Cash Payment  Amount in  accordance  with

                           not  terminate  or  expire  prior  to or  as of  such
                           termination.

                (c) In   the event that Parent  wishes to exercise the Option,
                           it shall send to such  Stockholder  a written  notice
                           (the date of which  being  herein  referred to as the

                           run instead  from the date on which such  restriction
                           on  consummation  has expired or been  terminated and
                           (ii)  without   limiting  the  foregoing,   if  prior
                           notification  to  or  approval  of  any  Governmental
                           Entity  (as  defined  in  the  Merger  Agreement)  is

                           required  notification  period  has  expired  or been
                           terminated  or (B) any  required  approval  has  been

                           bank   account   designated   in   writing   by  such
                           Stockholder.

                 (e) At   the Option Closing,  simultaneously with the delivery
                           of  the  amount   specified  in  Section  5(d),  each

                           shall be free and clear of all Liens, claims, charges
                           and encumbrances of any kind  whatsoever,  except for
                           such  encumbrances  or  proxies  in favor  of  Parent
                           arising  hereunder,  and a new Option  evidencing the
                           rights of the Parent (or its  designee)  to  purchase
                           the balance of such Stockholder's  shares purchasable
                           hereunder.

                  6. Cash Election.

                    (a) In lieu of exercising the Option, by notice,  Parent may
                           require  such  Stockholder  to make a cash payment to
                           Parent in the  amount  (the  "Cash  Payment  Amount")
                           equal to the amount by which (A) the Market Price (as
                           defined below) exceeds (B) the Per Share Cash Amount,
                           multiplied  by the  sum of (i)  the  number  of  such
                           Stockholder's  Shares  and  (ii) the  number  of such
                           Stockholder's  New  Shares.   Upon  receipt  of  such
                           notice,  the Stockholder shall be permitted to sell a
                           sufficient  number of Shares to pay the Cash  Payment
                           Amount,  if Stockholder  shall,  within five business
                           days of such notice, sell such Shares,  provided that
                           Stockholder  shall use  reasonable  best  efforts  to
                           achieve good  execution and shall consult with Parent
                           with respect to the manner of  disposition.  The term
                           "Market  Price"  shall  mean the  closing  price  (as
                           measured by the last  completed  trade) for shares of
                           Common Stock on the date of Parent's election,  or if
                           Stockholder  elects  to sell  Shares  to pay the Cash
                           Payment  Amount and has complied  with the proviso to
                           the immediately preceding sentence, the average price
                           per Share actually realized in such sale.

                (b) Parent may exercise its right to require such Stockholder to
                           pay the Cash Payment Amount  pursuant to this Section
                           by surrendering for such purpose to such Stockholder,
                           at the  Company's  principal  office,  a copy of this
                           Agreement, accompanied by a written notice or notices
                           stating   that   Parent   elects  to   require   such
                           Stockholder   to  pay  the  Cash  Payment  Amount  in
                           accordance  with  the  provisions  of  this  Section.
                           Within  five  (or,  in the  case of a sale of  Shares
                           under  (a)  above to fund the  Cash  Payment  Amount,
                           eight)  business  days  after  the  surrender  of the
                           Option  and the  receipt  of such  notice or  notices
                           relating  thereto,  such Stockholder shall deliver or
                           cause to be  delivered  to  Parent  the Cash  Payment
                           Amount by wire to the account designated by Parent in
                           immediately available funds.

                 (c) If   Stockholder at any time after delivery of a notice of
                           election  by Parent to take the Cash  Payment  Amount
                           pursuant  to  this   Section  is   prohibited   under

                           full,  and  Stockholder is required to sell Shares to
                           fund  the  Cash   Payment   Amount,   then  (i)  such
                           Stockholder    hereby    undertakes   to   use   such
                           Stockholder's  reasonable best efforts, to the extent
                           within the control of such Stockholder, to obtain all
                           required  regulatory and legal  approvals and to file
                           any  required  notices,  in each case as  promptly as
                           practicable  in order to  accomplish  such  sales and
                           (ii) if  Stockholder is unable to effect sales within
                           four  days  after  the   receipt   of  notice,   such
                           Stockholder  shall  be  permitted  to  pay  the  Cash
                           Payment  Amount to  Parent  in  Shares  valued at the
                           Market Price.

                 7. No Encumbrances.

                   (a) Except as expressly  contemplated   by  this   Agreement,

                           representing  such  Shares are now,  and at all times

                           Stockholder,  or by a nominee  or  custodian  for the
                           benefit  of such  Stockholder,  free and clear of all
                           liens, claims,  security interests,  proxies,  voting
                           trusts or agreements,  understandings or arrangements
                           or any other  encumbrances  whatsoever (other than to

                    employee stock options and tax  liabilities in respect of an
                    exercise of employee  stock  options;  provided  that Parent
                    shall  have a right of first  refusal to  purchase  such New

                    and provided  further  that, if any such New Shares are sold
                    or pledged  for an amount in excess of $23 per share and the

                    such excess over $23 per share  directly to Parent if Parent
                    ever  exercises  the Option;  and provided  further that any
                    such New Shares  shall be sold (or  pledged)  subject to the
                    irrevocable proxy referred to in paragraph 2.

                    such obligation, as described in Section 6(a) above.

               (iii)In  the  event  that  the  Merger  Agreement  is  terminated

                    not  due to the  willful  breach  of any  representation  or
                    warranty  or  the  willful  breach  of any  covenant  by the
                    Company),  any Stockholder  shall be permitted to sell up to
                    20% of such Stockholder's  Shares held as of the date hereof
                    if  reasonably   necessary  to  provide  liquidity  to  such
                    Stockholder if at such time no Acquisition Proposal shall be
                    pending or could reasonably expected to become pending prior
                    to  expiration  of the Option  and there  shall have been no
                    willful  breach of the Merger  Agreement or the Stock Option
                    Agreement   by  the  Company  or  this   Agreement  by  such
                    Stockholder;  provided  that  Parent  shall  have a right of
                    first  refusal to  purchase  such Shares at the lower of $23
                    per  share  or the  Market  Price  on  the  date  that  such
                    Stockholder  notifies  Parent of his intention to sell;  and
                    provided  further  that,  if any  such  Shares  are  sold or
                    pledged  for an  amount  in  excess of $23 per share and the
                    Option becomes  exercisable,  such  Stockholder  shall remit
                    such excess over $23 per share  directly to Parent if Parent
                    ever  exercises  the Option;  and provided  further that any
                    such New Shares  shall be sold (or  pledged)  subject to the
                    irrevocable proxy referred to in paragraph 2.

                 (c) Any  transfer  by  Stockholder  of its  Shares  to  Parent
                           pursuant   to   the   Option   shall   pass   to  and

                           Stockholder  will notify  Parent  immediately  if any
                           inquiries,   proposals   or  offers   respecting   an
                           Acquisition   Proposal  are  received  by,  any  such

                           that Parent is entering into the Merger  Agreement in
                           reliance upon Stockholder's execution and delivery of
                           this Agreement.

               12. Action  in Stockholder  Capacity Only.  Stockholder  makes no
                           agreement or understanding hereunder as a director or
                           officer  of  the  Company.   Stockholder  signs  this
                           Agreement  solely  in his  capacity  as a  beneficial
                           owner of the Shares,  and nothing  herein shall limit
                           or effect any actions taken in Stockholder's capacity
                           as an officer or director of the Company.

              13. Specific Performance.    Each    party    hereto    severally
                           acknowledges that it will be impossible to measure in
                           money the  damage to the other  parties  if the party
                           hereto  fails to comply  with any of the  obligations
                           imposed by this Agreement, that every such obligation
                           is  material  and  that,  in the  event  of any  such
                           failure,  the other parties will not have an adequate
                           remedy at law or  damages.  Accordingly,  each  party
                           hereto  severally  agrees that  injunctive  relief or
                           other  equitable  remedy,  in addition to remedies at
                           law or  damages,  is the  appropriate  remedy for any
                           such failure and will not oppose the granting of such
                           relief  on the  basis  that any  other  party  has an
                           adequate  remedy at law. Each party hereto  severally
                           agrees that it will not seek, and agrees to waive any
                           requirement for, the securing or posting of a bond in
                           connection   with  any  other   party's   seeking  or
                           obtaining such equitable relief.

                14. Heirs, Successors  and  Assigns.  This  Agreement  shall  be
                           binding  upon and inure to the benefit of the parties
                           hereto and their  respective  heirs,  successors  and
                           assigns  and  shall  not be  assignable  without  the
                           written  consent of all other  parties  hereto  other
                           than any assignment in whole or in part by Parent.

                15. Entire  Agreement.   This  Agreement supersedes  all  prior
                           agreements, written or oral, among the parties hereto
                           with  respect  to  the  subject   matter  hereof  and
                           contains the entire  agreement among the parties with
                           respect to the subject matter hereof.  This Agreement
                           may not be amended,  supplemented or modified, and no
                           provisions  hereof may be modified or waived,  except
                           by an instrument in writing signed by all the parties
                           hereto.  No  waiver of any  provisions  hereof by any
                           party   shall  be   deemed  a  waiver  of  any  other
                           provisions  hereof by any such  party,  nor shall any
                           such  waiver  be  deemed a  continuing  waiver of any
                           provision hereof by such party.

                           and make effective the  transactions  contemplated by
                           this Agreement.

                           this  Agreement  and shall  constitute  Shares to the
                           same extent as if they were owned by such Stockholder
                           on the date hereof.

                5. Option Shares.
                 (a) Subject to  the  terms  and conditions  set  forth  herein,
                           Stockholder  hereby  grants to Parent an  irrevocable
                           option (the  "Option")  to  purchase,  in whole or in
                           part,    such    Stockholder's    Shares   and   such
                           Stockholder's New Shares at a purchase price equal to
                           the Per Share Cash  Amount (as  defined in the Merger
                           Agreement) per share; provided,  however, that if the
                           Per Share Cash Amount  under the Merger  Agreement or
                           any amendment  thereto is ever increased or if Parent
                           shall  otherwise  offer  to the  Stockholders  of the
                           Company an increased  consideration  for all of their
                           shares  (the  "Greater   Consideration"),   then  the
                           purchase  price per share  under the Option  shall be
                           increased  to equal such new Per Share Cash Amount or
                           Greater  Consideration;  and provided further that if
                           Parent  has  exercised  the  Option  within 12 months
                           prior to such  increase  in the Per Share Cash Amount
                           or Greater  Consideration,  then Parent  shall pay to
                           each  Stockholder  an amount  equal to the product of
                           the number of shares  previously  purchased from such
                           Stockholder  pursuant to the Option and the amount of
                           increase  between  the old Per Share Cash  Amount and
                           the  new   Per   Share   Cash   Amount   or   Greater
                           Consideration, as applicable.

                 (b) Parent may exercise the Option, in whole or in part, at any
                           time and from time to time,  after the first to occur
                           of (i) any event as a result of which Parent shall be
                           entitled  to receive a  termination  fee  pursuant to

                           Agreement  (the  first of such  events  to  occur,  a
                           "Purchase Event"); provided,  however, that except as
                           provided in the last  sentence of this Section  5(b),
                           the Option shall terminate and be of no further force

                           the  Cash  Payment  Amount  if it has  given  written
                           notice  of its  intent  to  exercise  the  Option  or
                           receive the Cash Payment  Amount in  accordance  with

                           Option and the  termination  of the Option  shall not
                           affect any rights  hereunder  which by their terms do
                           not  terminate  or  expire  prior  to or  as of  such
                           termination.

                (c) In   the event that Parent  wishes to exercise the Option,
                           it shall send to such  Stockholder  a written  notice

                           "Notice  Date")  to that  effect  which  notice  also
                           specifies  the total  number of  shares  Parent  will
                           purchase  pursuant to such  exercise,  and a date not

                 (e) At   the Option Closing,  simultaneously with the delivery
                           of  the  amount   specified  in  Section  5(d),  each
                           Stockholder shall deliver to Parent (or its designee)

                           shall be free and clear of all Liens, claims, charges
                           and encumbrances of any kind  whatsoever,  except for
                           such  encumbrances  or  proxies  in favor  of  Parent
                           arising  hereunder,  and a new Option  evidencing the
                           rights of the Parent (or its  designee)  to  purchase
                           the balance of such Stockholder's  shares purchasable
                           hereunder.

                  6. Cash Election.

                    (a) In lieu of exercising the Option, by notice,  Parent may
                           require  such  Stockholder  to make a cash payment to
                           Parent in the  amount  (the  "Cash  Payment  Amount")
                           equal to the amount by which (A) the Market Price (as
                           defined below) exceeds (B) the Per Share Cash Amount,
                           multiplied  by the  sum of (i)  the  number  of  such
                           Stockholder's  Shares  and  (ii) the  number  of such
                           Stockholder's  New  Shares.   Upon  receipt  of  such
                           notice,  the Stockholder shall be permitted to sell a
                           sufficient  number of Shares to pay the Cash  Payment
                           Amount,  if Stockholder  shall,  within five business
                           days of such notice, sell such Shares,  provided that
                           Stockholder  shall use  reasonable  best  efforts  to
                           achieve good  execution and shall consult with Parent
                           with respect to the manner of  disposition.  The term
                           "Market  Price"  shall  mean the  closing  price  (as
                           measured by the last  completed  trade) for shares of
                           Common Stock on the date of Parent's election,  or if
                           Stockholder  elects  to sell  Shares  to pay the Cash
                           Payment  Amount and has complied  with the proviso to
                           the immediately preceding sentence, the average price
                           per Share actually realized in such sale.

                (b) Parent may exercise its right to require such Stockholder to
                           pay the Cash Payment Amount  pursuant to this Section
                           by surrendering for such purpose to such Stockholder,
                           at the  Company's  principal  office,  a copy of this
                           Agreement, accompanied by a written notice or notices
                           stating   that   Parent   elects  to   require   such
                           Stockholder   to  pay  the  Cash  Payment  Amount  in
                           accordance  with  the  provisions  of  this  Section.
                           Within  five  (or,  in the  case of a sale of  Shares
                           under  (a)  above to fund the  Cash  Payment  Amount,
                           eight)  business  days  after  the  surrender  of the
                           Option  and the  receipt  of such  notice or  notices
                           relating  thereto,  such Stockholder shall deliver or
                           cause to be  delivered  to  Parent  the Cash  Payment
                           Amount by wire to the account designated by Parent in
                           immediately available funds.

                 (c) If   Stockholder at any time after delivery of a notice of
                           election  by Parent to take the Cash  Payment  Amount
                           pursuant  to  this   Section  is   prohibited   under

                           full,  and  Stockholder is required to sell Shares to
                           fund  the  Cash   Payment   Amount,   then  (i)  such
                           Stockholder    hereby    undertakes   to   use   such
                           Stockholder's  reasonable best efforts, to the extent
                           within the control of such Stockholder, to obtain all
                           required  regulatory and legal  approvals and to file
                           any  required  notices,  in each case as  promptly as
                           practicable  in order to  accomplish  such  sales and
                           (ii) if  Stockholder is unable to effect sales within
                           four  days  after  the   receipt   of  notice,   such
                           Stockholder  shall  be  permitted  to  pay  the  Cash
                           Payment  Amount to  Parent  in  Shares  valued at the
                           Market Price.

                 7. No Encumbrances.

                   (a) Except as expressly  contemplated   by  this   Agreement,
                           Stockholder's    Shares    and    the    certificates
                           representing  such  Shares are now,  and at all times
                           during  the  term   hereof  will  be,  held  by  such
                           Stockholder,  or by a nominee  or  custodian  for the
                           benefit  of such  Stockholder,  free and clear of all
                           liens, claims,  security interests,  proxies,  voting
                           trusts or agreements,  understandings or arrangements
                           or any other  encumbrances  whatsoever (other than to
                           the   extent   set  forth  on   Schedule  1  to  this
                           Agreement),  except  for  any  such  encumbrances  or
                           proxies arising hereunder.

                 (b) Notwithstanding the foregoing:

               (i)  Stockholder  shall be  permitted  to sell (or  pledge to the
                    Company in  support  of a loan)  such  portion of New Shares
                    (but may not  sell  any New  Shares  to the  Company  or its
                    Subsidiaries)  solely  to  pay  the  exercise  price  of any
                    employee stock options and tax  liabilities in respect of an
                    exercise of employee  stock  options;  provided  that Parent
                    shall  have a right of first  refusal to  purchase  such New
                    Shares at the lower of $23 per  share or the  Market  Price;
                    and provided  further  that, if any such New Shares are sold
                    or pledged  for an amount in excess of $23 per share and the
                    Option becomes  exercisable,  such  Stockholder  shall remit
                    such excess over $23 per share  directly to Parent if Parent
                    ever  exercises  the Option;  and provided  further that any
                    such New Shares  shall be sold (or  pledged)  subject to the
                    irrevocable proxy referred to in paragraph 2.

               (ii) Any  Stockholder  which has received a notice of election by
                    Parent (or its designee) to receive the Cash Payment  Amount
                    shall be permitted,  between  receipt

                    time on which the Cash Payment  Amount is due to be paid, to
                    sell such  number of Shares as may be  necessary  to satisfy
                    such obligation, as described in Section 6(a) above.

               (iii)In  the  event  that  the  Merger  Agreement  is  terminated
                    pursuant  to Section  7.1(d) or 7.1(g)  (based upon a breach
                    not  due to the  willful  breach  of any  representation  or
                    warranty  or  the  willful  breach  of any  covenant  by the
                    Company),  any Stockholder  shall be permitted to sell up to
                    20% of such Stockholder's  Shares held as of the date hereof
                    if  reasonably   necessary  to  provide  liquidity  to  such
                    Stockholder if at such time no Acquisition Proposal shall be
                    pending or could reasonably expected to become pending prior
                    to  expiration  of the Option  and there  shall have been no
                    willful  breach of the Merger  Agreement or the Stock Option
                    Agreement   by  the  Company  or  this   Agreement  by  such
                    Stockholder;  provided  that  Parent  shall  have a right of
                    first  refusal to  purchase  such Shares at the lower of $23
                    per  share  or the  Market  Price  on  the  date  that  such
                    Stockholder  notifies  Parent of his intention to sell;  and
                    provided  further  that,  if any  such  Shares  are  sold or
                    pledged  for an  amount  in  excess of $23 per share and the
                    Option becomes  exercisable,  such  Stockholder  shall remit
                    such excess over $23 per share  directly to Parent if Parent
                    ever  exercises  the Option;  and provided  further that any
                    such New Shares  shall be sold (or  pledged)  subject to the
                    irrevocable proxy referred to in paragraph 2.

                 (c) Any  transfer  by  Stockholder  of its  Shares  to  Parent
                           pursuant   to   the   Option   shall   pass   to  and
                           unconditionally  vest in Parent  good and valid title
                           to such Stockholder's Shares and New Shares, free and
                           clear of all claims,  liens,  restrictions,  security
                           interests,   pledges,  limitations  and  encumbrances
                           whatsoever.

                 8. Acquisition   Proposals.  Stockholder   agrees   that   such
                           Stockholder  (i) shall not,  directly or  indirectly,

               11. Relianceby Parent.  Stockholder  understands and acknowledges
                           that Parent is entering into the Merger  Agreement in

                           this Agreement.

               12. Action  in Stockholder  Capacity Only.  Stockholder  makes no
                           agreement or understanding hereunder as a director or
                           officer  of  the  Company.   Stockholder  signs  this
                           Agreement  solely  in his  capacity  as a  beneficial
                           owner of the Shares,  and nothing  herein shall limit

                           as an officer or director of the Company.

              13. Specific Performance.    Each    party    hereto    severally
                           acknowledges that it will be impossible to measure in
                           money the  damage to the other  parties  if the party
                           hereto  fails to comply  with any of the  obligations
                           imposed by this Agreement, that every such obligation
                           is  material  and  that,  in the  event  of any  such
                           failure,  the other parties will not have an adequate
                           remedy at law or  damages.  Accordingly,  each  party
                           hereto  severally  agrees that  injunctive  relief or
                           other  equitable  remedy,  in addition to remedies at
                           law or  damages,  is the  appropriate  remedy for any
                           such failure and will not oppose the granting of such
                           relief  on the  basis  that any  other  party  has an
                           adequate  remedy at law. Each party hereto  severally
                           agrees that it will not seek, and agrees to waive any
                           requirement for, the securing or posting of a bond in
                           connection   with  any  other   party's   seeking  or
                           obtaining such equitable relief.

                14. Heirs, Successors  and  Assigns.  This  Agreement  shall  be
                           binding  upon and inure to the benefit of the parties
                           hereto and their  respective  heirs,  successors  and
                           assigns  and  shall  not be  assignable  without  the
                           written  consent of all other  parties  hereto  other
                           than any assignment in whole or in part by Parent.

                15. Entire  Agreement.  This  Agreement   supersedes  all  prior
                           agreements, written or oral, among the parties hereto
                           with  respect  to  the  subject   matter  hereof  and
                           contains the entire  agreement among the parties with
                           respect to the subject matter hereof.  This Agreement

                           provisions  hereof may be modified or waived,  except
                           by an instrument in writing signed by all the parties
                           hereto.  No  waiver of any  provisions  hereof by any
                           party   shall  be   deemed  a  waiver  of  any  other
                           provisions  hereof by any such  party,  nor shall any
                           such  waiver  be  deemed a  continuing  waiver of any
                           provision hereof by such party.

                           this  Agreement  and shall  constitute  Shares to the
                           same extent as if they were owned by such Stockholder

                           Stockholder  hereby  grants to Parent an  irrevocable
                           option (the  "Option")  to  purchase,  in whole or in
                           part,    such    Stockholder's    Shares   and   such
                           Stockholder's New Shares at a purchase price equal to
                           the Per Share Cash  Amount (as  defined in the Merger
                           Agreement) per share; provided,  however, that if the
                           Per Share Cash Amount  under the Merger  Agreement or
                           any amendment  thereto is ever increased or if Parent
                           shall  otherwise  offer  to the  Stockholders  of the
                           Company an increased  consideration  for all of their
                           shares  (the  "Greater   Consideration"),   then  the
                           purchase  price per share  under the Option  shall be
                           increased  to equal such new Per Share Cash Amount or
                           Greater  Consideration;  and provided further that if
                           Parent  has  exercised  the  Option  within 12 months
                           prior to such  increase  in the Per Share Cash Amount
                           or Greater  Consideration,  then Parent  shall pay to
                           each  Stockholder  an amount  equal to the product of
                           the number of shares  previously  purchased from such
                           Stockholder  pursuant to the Option and the amount of
                           increase  between  the old Per Share Cash  Amount and
                           the  new   Per   Share   Cash   Amount   or   Greater
                           Consideration, as applicable.

                 (b) Parent may exercise the Option, in whole or in part, at any
                           time and from time to time,  after the first to occur
                           of (i) any event as a result of which Parent shall be
                           entitled  to receive a  termination  fee  pursuant to

                           "Purchase Event"); provided,  however, that except as
                           provided in the last  sentence of this Section  5(b),

                           termination  of the Merger  Agreement  in  accordance
                           with  Section  7.1(a),  (b), (c) or (h) of the Merger

                           the  Cash  Payment  Amount  if it has  given  written
                           notice  of its  intent  to  exercise  the  Option  or
                           receive the Cash Payment  Amount in  accordance  with

                           affect any rights  hereunder  which by their terms do
                           not  terminate  or  expire  prior  to or  as of  such
                           termination.

                (c) In   the event that Parent  wishes to exercise the Option,
                           it shall send to such  Stockholder  a written  notice

                           "Notice  Date")  to that  effect  which  notice  also
                           specifies  the total  number of  shares  Parent  will
                           purchase  pursuant to such  exercise,  and a date not

                           required  notification  period  has  expired  or been
                           terminated  or (B) any  required  approval  has  been

                 (e) At   the Option Closing,  simultaneously with the delivery
                           of  the  amount   specified  in  Section  5(d),  each
                           Stockholder shall deliver to Parent (or its designee)
                           a certificate or certificates representing its shares
                           to be purchased at the Option  Closing,  which shares
                           shall be free and clear of all Liens, claims, charges
                           and encumbrances of any kind  whatsoever,  except for
                           such  encumbrances  or  proxies  in favor  of  Parent
                           arising  hereunder,  and a new Option  evidencing the
                           rights of the Parent (or its  designee)  to  purchase
                           the balance of such Stockholder's  shares purchasable
                           hereunder.

                  6. Cash Election.

                    (a) In lieu of exercising the Option, by notice,  Parent may
                           require  such  Stockholder  to make a cash payment to
                           Parent in the  amount  (the  "Cash  Payment  Amount")
                           equal to the amount by which (A) the Market Price (as
                           defined below) exceeds (B) the Per Share Cash Amount,
                           multiplied  by the  sum of (i)  the  number  of  such
                           Stockholder's  Shares  and  (ii) the  number  of such
                           Stockholder's  New  Shares.   Upon  receipt  of  such
                           notice,  the Stockholder shall be permitted to sell a
                           sufficient  number of Shares to pay the Cash  Payment
                           Amount,  if Stockholder  shall,  within five business
                           days of such notice, sell such Shares,  provided that
                           Stockholder  shall use  reasonable  best  efforts  to
                           achieve good  execution and shall consult with Parent
                           with respect to the manner of  disposition.  The term
                           "Market  Price"  shall  mean the  closing  price  (as
                           measured by the last  completed  trade) for shares of
                           Common Stock on the date of Parent's election,  or if
                           Stockholder  elects  to sell  Shares  to pay the Cash
                           Payment  Amount and has complied  with the proviso to
                           the immediately preceding sentence, the average price
                           per Share actually realized in such sale.

                (b) Parent may exercise its right to require such Stockholder to
                           pay the Cash Payment Amount  pursuant to this Section
                           by surrendering for such purpose to such Stockholder,
                           at the  Company's  principal  office,  a copy of this
                           Agreement, accompanied by a written notice or notices
                           stating   that   Parent   elects  to   require   such
                           Stockholder   to  pay  the  Cash  Payment  Amount  in
                           accordance  with  the  provisions  of  this  Section.
                           Within  five  (or,  in the  case of a sale of  Shares
                           under  (a)  above to fund the  Cash  Payment  Amount,
                           eight)  business  days  after  the  surrender  of the
                           Option  and the  receipt  of such  notice or  notices
                           relating  thereto,  such Stockholder shall deliver or
                           cause to be  delivered  to  Parent  the Cash  Payment
                           Amount by wire to the account designated by Parent in
                           immediately available funds.

                 (c) If   Stockholder at any time after delivery of a notice of
                           election  by Parent to take the Cash  Payment  Amount
                           pursuant  to  this   Section  is   prohibited   under
                           applicable  law or regulation  from selling Shares in
                           order to deliver to Parent the Cash Payment Amount in
                           full,  and  Stockholder is required to sell Shares to
                           fund  the  Cash   Payment   Amount,   then  (i)  such
                           Stockholder    hereby    undertakes   to   use   such
                           Stockholder's  reasonable best efforts, to the extent
                           within the control of such Stockholder, to obtain all
                           required  regulatory and legal  approvals and to file
                           any  required  notices,  in each case as  promptly as
                           practicable  in order to  accomplish  such  sales and
                           (ii) if  Stockholder is unable to effect sales within
                           four  days  after  the   receipt   of  notice,   such
                           Stockholder  shall  be  permitted  to  pay  the  Cash
                           Payment  Amount to  Parent  in  Shares  valued at the
                           Market Price.

                 7. No Encumbrances.

                   (a) Except as expressly  contemplated   by  this   Agreement,
                           Stockholder's    Shares    and    the    certificates
                           representing  such  Shares are now,  and at all times
                           during  the  term   hereof  will  be,  held  by  such
                           Stockholder,  or by a nominee  or  custodian  for the
                           benefit  of such  Stockholder,  free and clear of all
                           liens, claims,  security interests,  proxies,  voting
                           trusts or agreements,  understandings or arrangements
                           or any other  encumbrances  whatsoever (other than to
                           the   extent   set  forth  on   Schedule  1  to  this
                           Agreement),  except  for  any  such  encumbrances  or
                           proxies arising hereunder.

                 (b) Notwithstanding the foregoing:

               (i)  Stockholder  shall be  permitted  to sell (or  pledge to the
                    Company in  support  of a loan)  such  portion of New Shares
                    (but may not  sell  any New  Shares  to the  Company  or its
                    Subsidiaries)  solely  to  pay  the  exercise  price  of any
                    employee stock options and tax  liabilities in respect of an
                    exercise of employee  stock  options;  provided  that Parent
                    shall  have a right of first  refusal to  purchase  such New
                    Shares at the lower of $23 per  share or the  Market  Price;
                    and provided  further  that, if any such New Shares are sold
                    or pledged  for an amount in excess of $23 per share and the
                    Option becomes  exercisable,  such  Stockholder  shall remit
                    such excess over $23 per share  directly to Parent if Parent
                    ever  exercises  the Option;  and provided  further that any
                    such New Shares  shall be sold (or  pledged)  subject to the
                    irrevocable proxy referred to in paragraph 2.

               (ii) Any  Stockholder  which has received a notice of election by
                    Parent (or its designee) to receive the Cash Payment  Amount
                    shall be permitted,  between  receipt

                    time on which the Cash Payment  Amount is due to be paid, to
                    sell such  number of Shares as may be  necessary  to satisfy
                    such obligation, as described in Section 6(a) above.

               (iii)In  the  event  that  the  Merger  Agreement  is  terminated
                    pursuant  to Section  7.1(d) or 7.1(g)  (based upon a breach
                    not  due to the  willful  breach  of any  representation  or
                    warranty  or  the  willful  breach  of any  covenant  by the
                    Company),  any Stockholder  shall be permitted to sell up to
                    20% of such Stockholder's  Shares held as of the date hereof
                    if  reasonably   necessary  to  provide  liquidity  to  such
                    Stockholder if at such time no Acquisition Proposal shall be
                    pending or could reasonably expected to become pending prior
                    to  expiration  of the Option  and there  shall have been no
                    willful  breach of the Merger  Agreement or the Stock Option
                    Agreement   by  the  Company  or  this   Agreement  by  such
                    Stockholder;  provided  that  Parent  shall  have a right of
                    first  refusal to  purchase  such Shares at the lower of $23
                    per  share  or the  Market  Price  on  the  date  that  such
                    Stockholder  notifies  Parent of his intention to sell;  and
                    provided  further  that,  if any  such  Shares  are  sold or

               11. Relianceby Parent.  Stockholder  understands and acknowledges
                           that Parent is entering into the Merger  Agreement in

                           this Agreement.

               12. Action  in Stockholder  Capacity Only.  Stockholder  makes no
                           agreement or understanding hereunder as a director or
                           officer  of  the  Company.   Stockholder  signs  this
                           Agreement  solely  in his  capacity  as a  beneficial
                           owner of the Shares,  and nothing  herein shall limit
                           or effect any actions taken in Stockholder's capacity
                           as an officer or director of the Company.

              13. Specific Performance.    Each    party    hereto    severally
                           acknowledges that it will be impossible to measure in
                           money the  damage to the other  parties  if the party
                           hereto  fails to comply  with any of the  obligations
                           imposed by this Agreement, that every such obligation
                           is  material  and  that,  in the  event  of any  such
                           failure,  the other parties will not have an adequate
                           remedy at law or  damages.  Accordingly,  each  party
                           hereto  severally  agrees that  injunctive  relief or
                           other  equitable  remedy,  in addition to remedies at
                           law or  damages,  is the  appropriate  remedy for any
                           such failure and will not oppose the granting of such
                           relief  on the  basis  that any  other  party  has an
                           adequate  remedy at law. Each party hereto  severally
                           agrees that it will not seek, and agrees to waive any
                           requirement for, the securing or posting of a bond in
                           connection   with  any  other   party's   seeking  or
                           obtaining such equitable relief.

                14. Heirs, Successors  and  Assigns.  This  Agreement  shall  be
                           binding  upon and inure to the benefit of the parties
                           hereto and their  respective  heirs,  successors  and
                           assigns  and  shall  not be  assignable  without  the
                           written  consent of all other  parties  hereto  other
                           than any assignment in whole or in part by Parent.

                15. Entire  Agreement.   This  Agreement  supersedes  all  prior
                           agreements, written or oral, among the parties hereto
                           with  respect  to  the  subject   matter  hereof  and
                           contains the entire  agreement among the parties with
                           respect to the subject matter hereof.  This Agreement

                           provisions  hereof may be modified or waived,  except
                           by an instrument in writing signed by all the parties
                           hereto.  No  waiver of any  provisions  hereof by any
                           party   shall  be   deemed  a  waiver  of  any  other
                           provisions  hereof by any such  party,  nor shall any
                           such  waiver  be  deemed a  continuing  waiver of any
                           provision hereof by such party.
