certificate  of  incorporation  or  by-laws of Parent or Merger  Sub,  any trust
agreement, loan or credit agreement,  note, bond, mortgage,  indenture, lease or

investment for Parent's and Merger Sub's own ac-

                                      -2-


count,  not as a nominee or agent and not with a view to the distribution of any
part  thereof.  Neither  Parent  nor  Merger Sub has any  present  intention  of
selling,  granting any  participation in or otherwise  distributing the same nor
does  Parent  or  Merger  Sub  have  any  contract,  undertaking,  agreement  or
arrangement  with any person with respect to any of the Subject Shares.  Each of
Parent and Merger Sub further  understands  that the  Subject  Shares may not be
sold,  transferred  or  otherwise  disposed  of without  registration  under the
Securities Act or pursuant to an exemption therefrom.

          3.  Covenants  of the  Stockholders.  Until  the  termination  of this
Agreement  in  accordance  with  Section 8  hereof,  the  Stockholders  agree as
follows:

          (a) Voting of Subject  Shares.  At any meeting of  stockholders of the
Company  called to vote  upon the  Merger  and the  Merger  Agreement  or at any
adjournment  thereof  or in any other  circumstances  upon which a vote or other
approval  with respect to the Merger and the Merger  Agreement  is sought,  each
Stockholder  shall vote its Subject Shares in favor of the Merger,  the adoption
by the Company of the Merger Agreement and the approval of the terms thereof and
each of the other transactions contemplated by the Merger Agreement.

          At any meeting of  stockholders  of the Company or at any  adjournment
thereof or in any other circumstances upon which the Stockholders' vote, consent
or other approval as stockholders are sought,  the  Stockholders  shall vote the
Subject Shares against (i) any action or agreement that would result in a breach
in any material respect of any covenant, representation or warranty or any other
obligation  or  agreement  of the Company  under the Merger  Agreement or of the
Stockholders  hereunder,  and (ii) any action or agreement that would reasonably
be expected to impede,  interfere with, delay, postpone or attempt to discourage
the Merger,  including, but not limited to: (A) the adoption by the Company of a
proposal regarding (1) the acquisition of the Company by merger, tender offer or
otherwise  by any  person  or group,  other  than  Parent  or Merger  Sub or any
designee thereof (a "Third Party"), or any other merger,  combination or similar
transaction with any Third Party; (2) the acquisition by a Third Party of 10% or
more of the assets of the Company and its  subsidiaries,  taken as a whole;  (3)
the  acquisition by a Third Party of 10% or more of the outstanding  Shares;  or
(4) the repurchase by the Company or any of its  subsidiaries  of 10% or more of
the  outstanding  Shares;  (B) any  amendment of the  Company's  certificate  of
incorporation or by-laws or other proposal or transaction  involving the Company
or any of its  subsidiaries,  which  amendment or other  proposal or transaction
would in any manner impede, frustrate, prevent or nullify the Merger, the Merger
Agreement or any of the other transactions  contemplated by the Merger Agreement
or change in any manner the voting rights of any class of the Company's  capital
stock;  (C) any change in the control of the board of  directors of the Company;
(D) any material change in the present  capitalization or dividend policy of the
Company;  or (E) any other material change in the Company's  corporate structure
or business.  The Stockholders  further agree not to commit or agree to take any
action inconsistent with the foregoing.

          (b)  Proxies.  As  security  for the  agreements  of the  Stockholders
provided for herein,  each Stockholder  hereby grants to Parent and Merger Sub a
proxy to vote the  Subject  Shares as  indicated  in Section  3(a)  above.  Each
Stockholder agrees that this proxy shall be ir-

                                      -3-


revocable  during the term of this  Agreement  and coupled  with an interest and
each of the Stockholders, Parent and Merger Sub will take such further action or
execute such other  instruments  as may be necessary to effectuate the intent of
this proxy and hereby revokes any proxy  previously  granted by any  Stockholder
with respect to any of the Subject Shares.

          (c) Transfer  Restrictions.  Each Stockholder  agrees not to (i) sell,
transfer,  pledge,  encumber,  assign or  otherwise  dispose  of or  hypothecate
(including by gift or by  contribution  or  distribution to any trust or similar
instrument  or  to  any   beneficiaries  of  such   Stockholder   (collectively,
"Transfer")),  or enter  into any  contract,  option  or  other  arrangement  or
understanding  (including  any profit sharing  arrangement)  with respect to the
Transfer of, any of the Subject  Shares other than  pursuant to the terms hereof
and  the  Merger   Agreement,   (ii)  enter  into  any  voting   arrangement  or
understanding  with  respect to the  Subject  Shares,  whether by proxy,  voting
agreement  or  otherwise,  or (iii) take any action  that  would  reasonably  be
expected  to make any of its  representations  or  warranties  contained  herein
untrue or incorrect  or could have the effect of  preventing  or disabling  such
Stockholder  from performing any of its obligations  hereunder.  Notwithstanding
the  foregoing,  each  Stockholder  may transfer  its Subject  Shares to another
direct or indirect wholly owned subsidiary of Onex Corporation on condition that
the  transferee  executes and delivers to Parent and Merger Sub an instrument in
writing, in form and substance reasonably satisfactory to Parent and Merger Sub,
assuming all of such Stockholder's obligations under this Agreement.

          (d) Appraisal Rights.  Each Stockholder  hereby irrevocably waives any
and all rights  which it may have as to  appraisal,  dissent  or any  similar or
related matter with respect to the Merger.

          (e)  No  Solicitation.  None  of the  Stockholders  nor  any of  their
affiliates shall (whether directly or indirectly through any officer,  director,
member,  advisor, agent,  representatives or other intermediary),  nor shall the
Stockholders  or any of  their  affiliates  authorize  or  permit  any of  their
officers,  directors,  members,  advisors,  agents,   representatives  or  other
intermediaries to, (i) solicit, initiate,  encourage or take any action intended
to or reasonably likely to facilitate any submission of inquiries,  proposals or
offers  from any person  relating  to any  acquisition  or  purchase of all or a
material  amount of assets of, or any equity  interest  in, the  Company (or any
subsidiary  or  division  thereof) or any merger,  consolidation,  tender  offer
(including  a  self  tender  offer),   exchange  offer,   business  combination,
recapitalization,  liquidation, dissolution or similar transaction involving the
Company (or any  subsidiary or division  thereof),  other than the  transactions
contemplated by this Agreement or the Merger Agreement, or any other transaction
the  consummation  of which would  reasonably  be expected to impede,  interfere
with,  prevent or  materially  delay the  Merger or which  would  reasonably  be
expected  to  materially  dilute  the  benefits  to Parent or Merger  Sub of the
transactions  contemplated by the Merger Agreement  (collectively,  "Transaction
Proposals")  or agree to or endorse  any  Transaction  Proposal,  other than the
transactions  contemplated  by the  Merger  Agreement,  or  (ii)  enter  into or
participate in any discussions or  negotiations  regarding any of the foregoing,
or furnish to any other person any  information  with  respect to the  Company's
business,  properties or assets or any of the foregoing,  or otherwise cooperate
in any way with, or assist or  participate  in,  facilitate  or  encourage,  any
effort  to  attempt  by any  other  person  to do or seek any of the  foregoing.
Notwithstanding any-


                                      -4-


thing in this  Agreement to the  contrary,  from and after the date hereof,  the
Stockholders  shall promptly  advise Parent and Merger Sub orally and in writing
of the receipt by any of them (or any of the other entities or persons  referred
to above) of any Transaction  Proposal or any inquiry which is likely to lead to
any Transaction Proposal,  the material terms and conditions of such Transaction
Proposal or inquiry,  and the identity of the person making any such Transaction
Proposal  or  inquiry.  The  Stockholders  will keep Parent and Merger Sub fully
informed of the status and details of any such Transaction  Proposal or inquiry.
Nothing in this Section shall restrict the activities of any individual (whether
or not an  affiliate of any  Stockholder)  in his or her capacity as a director,
officer, employee or agent of the Company or any of its subsidiaries.

          (f)  Merger  Agreement.   Each  Stockholder   accepts  the  terms  and
conditions of the Merger Agreement as they apply to the holders of Shares.

          4. Option.

          (a) The Stockholders hereby grant to Merger Sub (or its designee),  an
irrevocable  option to purchase the Subject Shares,  on the terms and subject to
the conditions set forth herein (the "Option").

          (b) The Option may be  exercised  by Merger Sub, as a whole and not in

          (i) the  Merger  Agreement  shall  have been  terminated  pursuant  to
     Section 10.1(b) thereof;

          (ii) the Merger  Agreement  shall  have been  terminated  pursuant  to
     Section 10.1(c) thereof (other than a termination by the Company  following

     by Parent or Merger Sub of their  respective  obligations  under the Merger
     Agreement);

          (iii) the Merger  Agreement  shall have been  terminated  pursuant  to
     Section 10.1(d) thereof;

     reason (other than a termination as a result of an actual  material  breach
     by Parent or Merger Sub of their  respective  obligations  under the Merger
     Agreement).

          (c) If Merger Sub wishes to exercise the Option, Merger Sub shall send
a written  notice to the  Stockholders  of its intention to exercise the Option,
specifying  the place,  and, if then known,  the time and the date (the  "Option
Closing Date") of the closing (the "Option Closing") of the purchase. The Option
Closing Date shall occur on the fifth  business day (or such later date as shall
be no later than five  business  days  following  the first time that the Option

                                      -5-


Closing shall be permitted by applicable law or  regulation)  after the later of
(i) the date on which such notice is delivered, and (ii) the satisfaction of the
conditions set forth in Section 4(f).

          (d) At the Option Closing,  the  Stockholders  shall deliver to Merger
Sub (or its designee) all of the Subject  Shares by delivery of a certificate or
certificates  evidencing  the  Subject  Shares  duly  endorsed  to Merger Sub or
accompanied  by powers duly  executed in favor of Merger Sub, with all necessary
stock transfer stamps affixed.

          (e) At the Option  Closing,  Merger Sub shall,  and Parent shall cause
Merger Sub to, pay to the  Stockholders  pursuant to the exercise of the Option,
by wire  transfer,  cash in immediately  available  funds to the accounts of the
Stockholders  (such  accounts to be specified in writing at least two days prior
to the Option Closing),  an amount equal to the product of $15.00 and the number
of Subject Shares (the "Subject Shares Purchase Price").

          (f) The Option Closing shall be subject to the satisfaction of each of
the following conditions:

          (i) no court,  arbitrator  or  governmental  body,  agency or official
     shall have  issued any order,  decree or ruling and there  shall not be any
     statute,  rule or regulation,  restraining,  enjoining or  prohibiting  the
     consummation of the purchase and sale of the Subject Shares pursuant to the
     exercise of the Option;

          (ii) any waiting period applicable to the consummation of the purchase
     and sale of the Subject Shares pursuant to the exercise of the Option under
     the HSR Act shall have expired or been terminated; and

          (iii) all  actions by or in  respect  of,  and any  filing  with,  any
     governmental  body, agency,  official,  or authority required to permit the
     consummation of the purchase and sale of the Subject Shares pursuant to the
     exercise  of the Option  shall have been  obtained  or made and shall be in
     full force and effect,  except such actions and filings which,  if not made
     or obtained,  would not,  individually  or in the aggregate,  reasonably be
     expected to have a Material Adverse Effect.

          5. Further Agreements of Parent and Merger Sub.

          (a) Parent and Merger Sub hereby agree that,  in the event that Merger
Sub  purchases  the  Subject  Shares  pursuant  to the  Option,  as  promptly as
practicable  thereafter,  Merger Sub will,  and Parent will cause Merger Sub to,
make a tender offer for the remaining  Shares to the stockholders of the Company
(the consummation of which shall be subject only to the condition that no court,
arbitrator or governmental body, agency or official shall have issued any order,
decree  or ruling  and  there  shall  not be any  statute,  rule or  regulation,
restraining,  enjoining or prohibiting  the  consummation  of such tender offer)
pursuant to which the  stockholders of the Company (other than the Company,  any
direct or  indirect  subsidiary  of the  Company  or Parent or Merger  Sub) will
receive an amount of cash consideration per Share equal to $15.00, and will take
such actions as may be  necessary or  appropriate  in order to  effectuate  such
tender offer at the earliest practicable time.

                                      -6-


          (b)  Subject to the last  sentence of this  Section  5(b),  if,  after
purchasing the Subject Shares  pursuant to the Option,  Merger Sub or any of its
affiliates  has not  acquired  the  remaining  Shares,  Merger Sub or any of its
affiliates receives any cash or non-cash consideration in respect of the Subject
Shares in connection with a Third Party Business  Combination (as defined below)
during the period commencing on the date of the Option Closing and ending on the
first  anniversary   thereof,   Merger  Sub  shall  promptly  pay  over  to  the
Stockholders,  as an addition to the Subject Shares Purchase Price, (x) one-half
of the excess, if any, of such  consideration  over the aggregate Subject Shares
Purchase  Price  paid  for the  Subject  Shares  which  are sold by  Merger  Sub
hereunder  less (y) the sum of (I) the amount of taxes  payable or to be payable
by Merger Sub (as estimated by Merger Sub in good faith) in connection with such
Third Party Business  Combination  (it being intended and understood that Merger
Sub retain  one-half of the after-tax  profit from such sale taking into account
any adjustment to basis  resulting  from the payment  required by this section),
and (II) the amount of expenses  of Merger Sub in  connection  herewith  and the
Merger  Agreement and in connection with such Third Party Business  Combination,
and  (II)  the pro  rata  portion  (based  on  share  holdings)  of all  capital
contributions  to and retained  earnings of the Company from the date of date of
the Option  Closing  through the date of the Third Party  Business  Combination;
provided  that,  (i)  if the  consideration  received  by  Merger  Sub  or  such
affiliates  shall be  securities  listed on a national  securities  exchange  or
traded on the Nasdaq National Market,  the per share value of such consideration
shall be equal to the closing price per share of such securities  listed on such
national  securities  exchange  or the Nasdaq  National  Market on the date such
transaction is consummated, and (ii) if the consideration received by Merger Sub
or such affiliates shall be in a form other than securities, the per share value
shall be determined in good faith as of the date such transaction is consummated
by Merger  Sub and the  Stockholders,  or, if  Merger  Sub and the  Stockholders
cannot reach  agreement,  by a  nationally  recognized  investment  banking firm
reasonably   acceptable  to  the  parties.   The  term  "Third  Party   Business
Combination"  means  the  occurrence  of any of the  following  events:  (A) the
Company,  or more than 50% of the  outstanding  shares of the Company's  capital
stock,  is acquired by merger or otherwise  by any Third  Party;  or (B) a Third
Party acquires all or  substantially  all of the total assets of the Company and
its subsidiaries, taken as a whole; provided, however, that in no event will any
transaction in which shares of the Company's  capital stock or any of its assets
are sold or transferred  directly or indirectly in connection  with or as a part
of a  sale  or  other  transaction  involving  sale,  merger  or  other  similar
transaction  of Parent or any of its  material  assets or business  constitute a
Third Party Business  Combination,  and in no event will a sale of any division,
line of business or similar unit of the Company and its subsidiaries  constitute
a Third Party Business Combination.

          6. Stop Transfer Order. The Stockholders  hereby authorize and request
the  Company's  counsel to notify the Company's  transfer  agent that there is a
stop  transfer  order with  respect to all of the Subject  Shares (and that this
Agreement places limits on the voting of the Subject Shares).

          7. Assignment. Neither this Agreement nor any of the rights, interests
or obligations  hereunder,  except as expressly  provided herein with respect to
Parent's and Merger  Sub's rights under the Option,  shall be assigned by any of
the parties without the prior written consent of the other parties,  except that
each of Parent or Merger Sub may assign,  in its sole discretion,

                                      -7-


any or all of its rights,  interests and obligations  hereunder to any direct or
indirect wholly owned subsidiary of Parent.  Subject to the preceding  sentence,
this Agreement will be binding upon,  inure to the benefit of and be enforceable
by the  parties and their  permitted  assigns  and their  respective  successors
(including  the Company as  successor  to Merger Sub  pursuant  to the  Merger),
heirs, agents, representatives,  trust beneficiaries,  attorneys, affiliates and
associates  and all of  their  respective  predecessors,  successors,  permitted
assigns, heirs, executors and administrators.

          8.  Termination.  This Agreement shall  terminate,  and no party shall
have any rights or obligations  hereunder and this  Agreement  shall become null
and void and have no further effect immediately  following the earliest to occur
of (x) the Effective  Time,  (y) the 30th day following the  termination  of the
Merger  Agreement  pursuant  to  Section  10.1(b),  10.1(c),  10.1(d) or 10.1(e)
thereof,  or (z) the  termination  of the Merger  Agreement  pursuant to Section
10.1(a) thereof.  Notwithstanding  the foregoing,  in the event the Option shall
have been  exercised in accordance  with Section 4, but the Option Closing shall
not have  occurred,  this  Agreement  shall  not  terminate,  except  that  this
Agreement may be terminated  by the  Stockholders  if Merger Sub defaults on its
obligation to purchase the Subject Shares at the Option Closing. Nothing in this
Section shall relieve any party of liability for breach of this Agreement.

          9. General Provisions.
