        of such Purchased  Asset arising after the Closing Date in trust for the
        Purchaser and cooperate with the Purchaser in any reasonable arrangement
        designed to provide for the  Purchaser the benefits with respect to such

                  Date;

         To the extent that the aggregate of the amounts calculated  pursuant to
         Section  3.3 is less  than  $1,000,000  and the  Purchaser  waives  the
         conditions  contained in subsection  6.2(k), the Parties agree that the
         portion of the Purchase Price  allocated to Goodwill shall be increased
         by such shortfall.

         The Purchaser acknowledges that the amount of the Initial Payment shall
         not be affected by the  allocation  determined  pursuant to subsections

         item-by-item  basis, the amount to be allocated thereto,  calculated as
         specified in Section 3.3.

         If the Purchaser disagrees with such allocations, within 30 days of the
         Closing,  such  dispute  shall be  submitted  for  determination  to an
         independent  firm of chartered  accountants,  mutually agreed to by the
         Vendors and Purchaser,  failing such  agreement,  to Ernst & Young LLP.
         Such determination  shall be final and binding on the Parties.  Each of
         the  Vendor  and  Purchaser  shall  bear the  costs  of its  respective
         accountants and other advisors and the costs of the independent firm of
         chartered  accountants  shall be borne equally  between the Vendors and
         the Purchaser.

3.5      FILINGS.  Each party shall file in mutually  agreeable form all returns

                        ARTICLE 9 - RESTRICTIVE COVENANTS

9.1      NON-COMPETITION;  NON-INTERFERENCE.  The  Companies  agree  that  for a
         period of five years after the Closing Date, the Vendors shall not, and
         shall  not  permit  any of  their  Affiliates  to,  either  alone or in
         conjunction with any other Person:

         (a)      own, manage, operate,  provide financing to, or participate in
                  the  ownership,   management,  operation  or  control  of,  or

<PAGE>
                  provision of financing  to, any business  wherever  located if
                  such  business  (i)  manufactures  or sells  any  products  or
                  services  in the field of  applications  of machine  vision or
                  (ii) sells any products competitive with the Products; or

                  respect  to  the  Business  or  the  Products  or in  any  way
                  interfere  with the  relationship  between any such  customer,
                  supplier, licensee, licensor, distributor or business relation
                  and the Purchaser with respect to the Business or the Products

                  or communications about the Purchaser or the Products).

9.2      CONFIDENTIAL INFORMATION. From and after the Closing, the Vendors shall
         not use or disclose or permit any of its  respective  Affiliates to use
         or disclose to any Person any trade secrets,  confidential information,
         know-how or other proprietary  information it possesses relating to the
         Business or the Products and shall use its best efforts to prevent such
         use or disclosure.

9.3      CERTAIN ACKNOWLEDGMENTS. The Vendors specifically acknowledge and agree
         that the  restrictions  set forth  herein are  reasonable  in scope and
         essential to the  preservation of the value of the Purchased Assets and
         the Business after the Closing.  The Vendors  further  acknowledge  and
         agree  that the remedy at law for any  breach of the  restrictions  set
         forth herein will be inadequate and that the Purchaser,  in addition to
         any other relief  available  to it, shall be entitled to temporary  and
         permanent  injunctive relief without the necessity of posting a bond or
         proving actual damage. In the event that the provisions of this Section
         9.3 should ever be held by a court to exceed the restrictions permitted
         by applicable  law, then the parties hereto agree that such  provisions
         shall be reformed to set forth the maximum  restrictions  permitted  by
         law.

9.4      TOLLING.  In the  event of any  breach by the  Vendor of the  covenants
         contained in Section 9.1 or 9.2, the running of the  applicable  period
         of  restriction  shall be  automatically  tolled and  suspended for the
         duration of such breach, and shall  automatically  recommence when such
         breach is remedied in order that the  Purchaser  shall receive the full
         benefit of the  Vendors'  compliance  with the  covenants  contained in
         Sections 9.1 and 9.2.

                            ARTICLE 10 - TERMINATION

10.1  TERMINATION.  This  Agreement  may be  terminated at any time prior to the
                    Closing:

         (a)      by mutual consent of the Purchaser and the Vendors; or

         (b)      by either the  Purchaser  or the Vendors if the Closing  shall
                  not have  been  consummated  on or  before  January  31,  2000
                  (provided  that  the  terminating  party is not  otherwise  in
                  material breach of its obligations under this Agreement).

10.2     EFFECT  OF  TERMINATION.  In the  event  of  the  termination  of  this
         Agreement  in  accordance  with  Section  10.1,  this  Agreement  shall
         thereafter  become void (other than  Sections 5.7 and 8.3,  which shall
         survive any termination hereof) and there shall be no obligation on the
         part of any  party  hereto  or their  respective  directors,  officers,
         stockholders  or  agents,

                                       25
<PAGE>
         except  that any such  termination  shall be without  prejudice  to the
         rights of any party hereto  arising out of the  material  breach by any
         other party of any covenant or agreement contained in this Agreement.

10.3     NON-COMPLETION  FEE.  Notwithstanding  Section  10.2, if for any reason
         other  than the fault  solely of the  Purchaser,  the  purchase  by the
         Purchaser  of  the  Purchased  Assets  at  the  Purchase  Price  is not
         completed or if a transaction  is completed on or before March 16, 2000
         pursuant to which the Purchased Assets or the shares of the Vendors are
         sold or a transaction is completed  which has the same effect as such a
         sale  of the  Purchased  Assets  or the  shares  of  the  Vendors  upon
         financial  terms  which are  equivalent  to or more  favourable  to the
         Vendors or its shareholders than the terms contained in this Agreement,
         then the Vendors  jointly and  severally  agree to  immediately  pay or
         cause the party  who  purchases  the  Purchased  Assets or any  portion
         thereof or the shares of the Vendor to immediately pay to the Purchaser
         a  non-completion  fee  of  $125,000,  which  the  parties  agree  is a
         reasonable  estimate  of costs  incurred  by Focus as a result  of this
         transaction  and  which  shall be  secured  by the  Purchaser  Security
         Agreement.

                          ARTICLE 11 - INDEMNIFICATION

11.1     INDEMNIFICATION BY THE COMPANIES.  Subject to the terms of this Article
         11,  the  Purchaser  shall  be  indemnified  and held  harmless  by the
         Companies  from and against  any  Liability,  loss,  damage or expense,
         including,  without limitation,  reasonable legal and accountants' fees
         (collectively,  "Losses"),  suffered or incurred by the Purchaser which
         arise out of or result from:

         (a)      any inaccuracy in or breach of any of the  representations and
                  warranties of the Vendors contained in Section 4.1; or

         (b)      any breach by either  Vendor of any  covenant or  agreement of
                  such Vendor contained in this Agreement; or

         (c)      any Companies' Liabilities; or

         (d)      the  ownership or operation of the Business on or prior to the
                  Closing Date, including without limitation, with respect to:

                  i)       wages,  salaries or benefits  of  employees,  and for
                           greater  clarity,  vacation  and sick  time  shall be
                           reconciled  by  either  Vendor  completely  up to the
                           Closing Date and all disability, benefits, insurance,
                           pension  and other  funds or plans  relating  to such
                           Vendor's  employees  shall be fully  funded as of the
                           Closing Date; and

                  ii)      the  termination  of the  employment of all of either
                           Vendor's employees; or

         (e)      any inaccuracy in any of the representations and warranties of
                  the Vendors contained in subsections  4.1(d), (i) or (w) as if
                  such  representations  and  warranties  had been made  without
                  reference   therein   to  "to  the  best  of  the   Companies'
                  Knowledge".

11.2     INDEMNIFICATION BY THE PURCHASER.  Subject to the terms of this Article
         11, the Vendors

                                       26
<PAGE>

         shall  be  indemnified  and held  harmless  by the  Purchaser  from and
         against any Losses suffered by the Vendors which arise out of or result
         from  any  inaccuracy  in or  breach  of any  of  the  representations,
         warranties,  covenants  or  agreements  made by the  Purchaser  in this
         Agreement.

11.3     METHOD OF ASSERTING THIRD PARTY CLAIMS. Promptly after the assertion by
         any third party of any claim,  demand or notice against any Person that
         may be entitled to  indemnification  under this Article 11 with respect
         to such claim (the  "INDEMNIFIED  PARTY"),  the Indemnified Party shall
         promptly notify the party from whom  indemnification may be sought (the
         "INDEMNIFYING  PARTY"),  specifying  the  nature of such  claim and the
         amount or the  estimated  amount  thereof to the extent  then  feasible
         (which  estimate  shall not be  conclusive  of the final amount of such
         claim)  (the "CLAIM  NOTICE").  Within  twenty days after  receipt of a
         Claim Notice (the "NOTICE PERIOD"),  the Indemnifying  Party may assume
         the defense of such claim; provided, however, that (i) the Indemnifying
         Party shall retain  counsel  reasonably  acceptable to the  Indemnified
         Party, (ii) the Indemnifying  Party agrees in writing that it is liable
         to indemnify the Indemnified  Party for all losses  resulting from such
         Claim,  and (iii) the  Indemnifying  Party shall not, without the prior
         written  consent of the  Indemnified  Party (which consent shall not be
         unreasonably  withheld  or  delayed),  enter into any  settlement  of a
         claim,  consent to the entry of any judgment with respect to a claim or
         cease  to  defend  a  claim,  if  pursuant  to or as a  result  of such
         settlement, consent or cessation,  injunctive or other equitable relief
         shall be imposed  against the  Indemnified  Party or if such settlement
         does not expressly and  unconditionally  release the Indemnified  Party
         from all Liabilities  with respect to such claim,  with prejudice.  The
         Indemnified  Party may  participate  in the  defense of such claim with
         co-counsel of its choice; provided, however, that the fees and expenses
         of the  Indemnified  Party's  counsel shall be paid by the  Indemnified
         Party  unless (A) the  Indemnifying  Party has agreed in writing to pay
         such fees and expenses, (B) the Indemnifying Party has failed to assume
         the defense and employ counsel as provided herein, or (C) a claim shall
         have been brought or asserted against the Indemnifying Party as well as
         the  Indemnified  Party,  and the  Indemnified  Party  shall  have been
         advised in writing  by  outside  counsel  that there may be one or more
         factual or legal  defenses  available  to it that are in conflict  with
         those  available  to  the  Indemnifying   Party,  in  which  case  such
         co-counsel  shall be at the expense of the  Indemnifying  Party. If the
         Indemnifying  Party  does not assume the  defense  of such  claim,  the
         Indemnified  Party may defend  against  the same in any manner  that it
         reasonably deems appropriate.

11.4     METHOD OF ASSERTING  DIRECT CLAIMS.  In the event an Indemnified  Party
         desires to assert a claim for  indemnification  against an Indemnifying
         Party that does not involve a third party, the Indemnified  Party shall
         promptly  send a  Claim  Notice  with  respect  to  such  claim  to the
         Indemnifying  Party.  If the  Indemnifying  Party  does not  notify the
         Indemnified Party within the Notice Period that it disputes such claim,
         the amount of Losses suffered or incurred by the Indemnified Party with
         respect to such claim shall be  conclusively  deemed a Liability of the
         Indemnifying Party hereunder.

11.5     SETOFF AGAINST  EARNOUT  PAYMENTS.  The Purchaser  shall be entitled to
         deduct  from and set off  against  the  Earnout  Amount  payable to the
         Vendors  the  amount  of  any  Losses  for  which  it  is  entitled  to
         indemnification  from the Companies  under Section 11.1 and may hold in
         reserve out of any payments in respect of the Earnout Amount  ("EARNOUT
         PAYMENT")  otherwise  due to the  Vendors  the  Purchaser's  reasonable
         estimate of Losses which may be incurred by the Purchaser  with respect
         to any claim for which a Claim

                                       27
<PAGE>

         Notice  has been given but which is not yet  resolved  at the time such
         Earnout  Payment  is due (an  "UNRESOLVED  CLAIM").  At such time as an
         Unresolved  Claim is finally  determined,  the amount of any Losses for
         which the  Purchaser  is entitled to  indemnification  shall be set off
         against the Earnout  Payments  withheld (and any other Earnout Payments
         which  remain  unpaid,  to the extent  that the  amount of such  Losses
         exceeds  the  amount  of  Earnout  Payments  previously  withheld)  and
         retained  by the  Purchaser,  and the  balance,  if any,  of the amount
         withheld  shall be promptly paid to the Vendors.  The  Purchaser  shall
         promptly  notify the Vendors of any setoff which the Purchaser  intends
         to make  against  any  Earnout  Payments  and of any  amount  which the
         Purchaser  intends to hold in reserve  with  respect to any  Unresolved
         Claims.

11.6     OTHER  INDEMNIFICATION  PAYMENTS.  Except  for  any  Losses  which  the
         Purchaser  elects  to set off  against  Earnout  Payments  pursuant  to
         Section 11.5,  all  indemnified  Losses shall be payable  within thirty
         days after the  Indemnified  Party notifies the  Indemnifying  Party or
         Parties  that such  Losses have been  suffered  or incurred  (including
         those relating to the on-going costs of defending third party claims in
         accordance with Section 11.3).

11.7     TAX   TREATMENT   OF   INDEMNIFICATION   PAYMENTS;   SUBROGATION.   Any
         indemnification  payment  made  pursuant  to this  Article  11 shall be
         treated by the parties  hereto as an adjustment  to the Purchase  Price
         for income tax purposes to the extent of the Purchase  Price.  Upon the
         payment  in  full  of  any  claim,  the  Indemnifying  Party  shall  be
         subrogated to the rights of the Indemnified Party against any Person or
         entity with respect to the subject matter of such claim.

11.8     SURVIVAL  OF   REPRESENTATIONS   AND  EARNOUT  COVENANT.   All  of  the
         representations  and  warranties  contained  in  this  Agreement  shall
         survive for a period of two years  following the Closing  Date,  except
         for (a) those  contained  in Sections  4.1(q) and  4.1(t),  which shall
         survive until three months  following the  expiration of the statute of
         limitations  applicable with respect to claims that constitute a breach
         of, or are the subject of, such representations and warranties, and (b)
         those  contained in Section 4.1(h) or those  fraudulently  made,  which
         shall survive indefinitely.  In addition, the Purchaser's obligation to
         pay the Earnout Amount shall survive until the later of (i) the Earnout
         Payment  Date or (ii) the date on which  the  Earnout  Amount  is fully
         paid.  No claim for  indemnification  may be made under this Article 11
         for breach of a  representation  or warranty  unless a Claim  Notice is
         given within the applicable survival period set forth herein.

11.9     FAILURE TO GIVE TIMELY  NOTICE.  Except as provided in Section  11.8, a
         failure by an  Indemnified  Party to give timely,  complete or accurate
         notice as  required  under  Sections  11.3 or 11.4 shall not affect the
         rights or  obligations  of any party  hereunder  except and only to the
         extent that, as a result of such failure, any party entitled to receive
         such notice was deprived of its right to recover any payment  under its
         applicable insurance coverage or was otherwise damaged or prejudiced as
         a result of such failure to give timely notice.

11.10    EXCLUSIVE REMEDY.  The rights of the parties to  indemnification  under
         this Agreement or with respect to the transactions  contemplated hereby
         shall be strictly  limited to those  contained  in this Article 11, and
         such  indemnification  rights  shall be the  exclusive  remedies of the
         parties  subsequent  to the Closing  Date with respect to any matter in
         any way relating to this  Agreement or arising in connection  herewith,
         except to the extent that the same shall have been the result of fraud.

12.4     NONASSIGNABILITY.  This  Agreement  shall not be  assigned  without the

12.8     SEVERABILITY.  If any term or provision of this Agreement shall, to any

<PAGE>

         Agreement  or the  application  of such term or provision to Persons or
         circumstances  other than those as to which it has been held invalid or
         unenforceable,  shall not be affected  thereby and this Agreement shall
         be deemed severable and shall be enforced  otherwise to the full extent

         connection with this Agreement, or the breach,  termination or validity
         hereof  including  claims by either  party for  indemnity  pursuant  to
         Article  11,  shall be settled by final and binding  arbitration  to be
         conducted by a single arbitrator in Toronto,  Ontario,  pursuant to the
         rules of the American Arbitration Association.  The parties shall agree
         upon  an  arbitrator  within  10 days of the  request  for  arbitration
         failing  which the party  initiating  arbitration  shall  nominate  one
         arbitrator  and the second party shall nominate a second within 10 days
         of the initiating party  nominating an arbitrator.  The two arbitrators
         so named  will then  jointly  appoint  the third  arbitrator  who shall
         conduct the  arbitration.  If the answering party fails to nominate its
         arbitrator  within the ten day period,  or if the arbitrators  named by
         the parties fail to agree on the third  arbitrator  within 10 days, the
         American Arbitration  Association shall make the necessary  appointment
         of such  arbitrator.  The decision or award of the arbitrator  shall be
         final,  and judgment  upon such decision or award may be entered in any
         competent  court or application  may be made to any competent court for
         judicial  acceptance  of  such  decision  or  award  and  an  order  of
         enforcement.  In the event of any procedural  matter not covered by the
         aforesaid  rules,  the  procedural law of the Province of Ontario shall
         govern.

                                  SCHEDULE 3.1
                   CALCULATION AND PAYMENT OF EARN-OUT AMOUNT
                   ------------------------------------------

(a)      In this Schedule 3.1,  capitalized terms shall have the same meaning as
         in the Asset Purchase  Agreement  except that the following terms shall
         have the meanings set out below:

                  "ANNUALIZED  WEIGHTED  AVERAGE  EARNOUT  AMOUNT" means, at any
                  time, the sum of: (i) for each Year completed prior to the end
                  of the month  preceding  the  Transaction  Closing Date or the
                  Optional Payment Date, as the case may be, the Net Earnings of
                  the Purchaser  attributable  to sales of the Products for such
                  completed  Year  multiplied  by the fraction the  numerator of
                  which  is  the   weighting   factor  for  such  Year  and  the
                  denominator  (the  "DENOMINATOR")  of  which is the sum of the
                  weighting factors from all Years completed prior to the end of
                  the  month  preceding  the  Transaction  Closing  Date  or the
                  Optional  Payment Date, as the case may be, plus the weighting
                  factor for the Partial Year (if any); and (ii) where the month
                  end of the month preceding the Transaction Closing Date is not
                  the end of a Year, the Net Earnings for the period  commencing
                  the first day of the then current Year and ending on the month
                  end  date  preceding  the  Transaction  Closing  Date  or  the
                  Optional  Payment Date, as the case may be (a "PARTIAL  YEAR")
                  multiplied  by the  fraction  the  numerator  of  which is the
                  weighting  factor for the Partial Year and the  denominator of
                  which is the  Denominator,  which sum of (i) and (ii) above is
                  then multiplied by the P/E Multiple and further  multiplied by
                  the Added Value Factor;

                  "ADJUSTED  WEIGHTED  AVERAGE  EARNOUT AMOUNT" means the sum of
                  (i) for each  Year  completed  prior  to the end of the  month
                  preceding  the  Optional  Payment  Date  (except  the  Year  1

         Amount to the Vendors shall fully satisfy the Purchaser's obligation to
         pay the Earnout Amount.

(h)      Not later than 45 business days following the end of each of Year 1, 2,

         forth in a written notice (the  "VENDORS'  NOTICE") from the Vendors to
         the  Purchaser  within  15  days of  receipt  of the  Purchaser  Notice
         specifying the details of such  disagreement  (if a Vendors'  Notice is
         not given  within  such 15 day period,  the Vendors  shall be deemed to
         have conclusively accepted the Purchaser's  determination as set out in
         the Purchaser's Notice),  such specific disagreement shall be submitted
         for  determination  to an  independent  firm of chartered  accountants,
         mutually  agreed to by the  Vendors  and  Purchaser,  or  failing  such
         agreement within 10 days of the Vendors' Notice,  to Ernst & Young LLP.
         Such determination  shall be final and binding on the Parties.  Each of
         the  Vendor  and  Purchaser  shall  bear the  costs  of its  respective
         accountants and other advisors and the costs of the independent firm of
         chartered accountants shall be borne entirely by the Vendor.

(i)      Prior to the  Earnout  Payment  Date,  Focus  shall  not  impose on the
         Purchaser any charge in the nature of a parent corporation  general and
         administrative  charge,  but shall  limit  charges  which it imposes to
         costs  incurred  or  expenses  or taxes  paid by Focus  for the  direct
         benefit  of the  Purchaser,  such  as,  without  limitation,  insurance
         premiums for insurance placed on the Purchaser's business and property,
         accounting fees, for review of the Purchaser's financial statements, as
         allocated to the Purchaser by Focus's accountants,  interest charges in
         respect of capital loaned to the Purchaser by Focus,  taxes relating to
         the  Purchaser's  operations and assets and other services  provided by
         Focus.

(j)      Notwithstanding  any other provision of the Asset Purchase Agreement or
         this  Schedule  3.1,  the Earnout  Amount  otherwise  payable  shall be
         reduced by the amount of the Working Capital Advances as at the date of
         payment  of the  Earnout  Amount  together  with  interest  thereon  as
         provided in the Purchaser Note as at the date of payment of the Earnout
         Amount.

(k)      The Vendors  hereby  irrevocably  direct the  Purchaser to pay from the
         Earnout  Amount (after  application  of the provisions of paragraph (j)
         above)(and in priority to payment of any portion of the Earnout  Amount
         to the Vendors):

                  (i)      to Charles M. Leighton,  an amount equal to 5% of the
                           first U.S. $1,000,000 of the aggregate of the Initial
                           Payment and the Earnout Amount (such  aggregate,  the

                           to 3% of the Fee Base.

                  To the  extent  that  some  or all of the  Earnout  Amount  is
                  satisfied by the  issuance of shares of Focus  pursuant to the
                  provisions  of (f)  above,  then the  amounts  in (i) and (ii)
                  above shall be satisfied in the same  proportions  of cash and
                  shares as the Earnout Amount is satisfied.

(l)      Upon payment or  satisfaction  by the Purchaser of the Earnout  Amount,
         the Vendors shall forthwith cause the Earnout Security  Agreement to be
         discharged and released and if the Vendors fail to do so, the Purchaser
         is hereby  authorized  as  attorney  to take all steps and  execute all
         documents necessary to do so.



(m)      The  Purchaser  agrees that until the  Earnout  Amount has been paid it
         shall maintain  accounting  records distinct from those of Focus or any
         other entity.  For the purposes of SCHEDULE 3.1, the Business  shall be
         deemed  to  include  any  property  acquired  by the  Purchaser  in the
         ordinary course of business,  any property acquired in substitution for
         Purchased  Assets  disposed of  subsequent  to the Closing Date and any
         additional  or new products  developed by the  Purchaser in  connection
         with the  Business  as it exists at the  Closing  Date or as it is from
         time to time thereafter.

                              ---------------------

         This  STOCKHOLDER'S   VOTING  AGREEMENT  AND  IRREVOCABLE  PROXY  (this

                                    RECITALS

         WHEREAS, Focus and IIC have entered into an Asset Purchase Agreement of
even date  herewith  (as such  agreement  may  hereafter be amended from time to
time, the "Purchase Agreement") whereby Focus will purchase substantially all of
the  assets  of IIC  and of AOI  International,  Inc.,  a  Delaware  corporation
("AOI"), a wholly owned subsidiary of IIC;

         WHEREAS,  pursuant to the Purchase  Agreement,  among other things, IIC
and AOI has agreed to sell and deliver to Focus  substantially all of the assets
of IIC and AOI,  free  and  clear  of all  liens,  pledges,  charges  and  other
encumbrances (the "Purchase and Sale"); and

         WHEREAS,  as an  inducement of and a condition to its entering into the
Purchase   Agreement,   Focus  has  required  that  IIC  and  certain  Principal
Stockholders agree to enter into this Agreement.

         NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  mutual

                               CERTAIN DEFINITIONS

         SECTION 1.01.  DEFINITIONS.

         (a)  Capitalized  terms  used but not  defined  herein  shall  have the
meanings assigned to such terms in the Purchase Agreement.

         (b)  "Beneficially  Own" or "Beneficial  Ownership" with respect to any
securities  shall mean having  "beneficial  ownership"  of such  securities  (as
determined  pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act")), including pursuant to any agreement,  arrangement
or understanding, whether or not in writing. Without duplicative counting of the
same securities by the same holder,  securities  Beneficially  Owned by a person
shall include securities  Beneficially Owned by all other persons with whom such
person would  constitute a "group" within the meaning of Section 13(d)(3) of the
Exchange Act.


<PAGE>

         (c) "Owned  Shares"  shall mean  shares of IIC  common  stock  owned or
Beneficially Owned by the Stockholder.

         (d) "Person" shall mean an individual, corporation, trust, partnership,

                                   ARTICLE II

                          COVENANTS OF THE STOCKHOLDER

         SECTION 2.01.  AGREEMENT TO VOTE. At any meeting of the Shareholders of
IIC held prior to the  Termination  Date (as defined in Section  5.06),  however
called,  and at every  adjournment  thereof prior to the Termination Date, or in
connection  with any written  consent of the  Shareholders of IIC given prior to
the  Termination  Date,  subject to the last sentence of this Section 2.01,  the
Stockholder  shall vote all of the Owned Shares that the Stockholder is entitled
to vote,  (i) in favor of IIC's  entering into and  performing  the  obligations
under the Purchase  Agreement  (as amended from time to time),  (ii) against any
proposal  for any  recapitalization,  merger,  sale of assets,  sale of stock or
other business  combination  between or among IIC, AOI or any other Affiliate of
IIC,  on the one hand,  and any other  person or entity  other than Focus or any
Affiliate of Focus,  on the other hand, or any other action or  agreement,  that
would  result in a breach of any  representation,  warranty,  covenant  or other
obligation or agreement of AOI or IIC under the Purchase Agreement or that would
result in any of the  conditions to the  obligations of Focus under the Purchase
Agreement not being fulfilled,  and (iii) in favor of any other matter necessary
for the consummation of the transactions  contemplated by the Purchase Agreement
with respect to which the Shareholders may be entitled to vote.

         The Stockholder, in furtherance of the transactions contemplated hereby
and by the Purchase  Agreement,  and in order to secure the  performance  by the
Stockholder of its duties and  obligations  under this  Agreement,  shall,  upon
execution of this Agreement,  execute and deliver to Focus an irrevocable proxy,
substantially in the form attached hereto as Exhibit A, and irrevocably  appoint
two of Focus'  designees its attorneys,  agents and proxies to vote (or cause to
be voted) or, if applicable, to give consent, in the manner, and with respect to
the matters, set forth above. The Stockholder agrees that the proxy executed and
delivered by it shall be coupled with an interest,  and shall constitute,  among
other things, an inducement for Focus to enter into the Purchase Agreement,  and
shall  be  irrevocable  and  binding  on any  successor  in  interest  upon  the
occurrence of any event.  Such proxy shall operate to revoke and render void any
prior proxy as to the Owned Shares heretofore  granted by the undersigned.  Such
proxy shall terminate upon the  Termination  Date (as defined in Section 5.06 of
this Agreement).

         SECTION 2.02.  PROXIES AND VOTING AGREEMENTS.

         (a) The Stockholder hereby revokes any and all previous proxies granted
with  respect to matters set forth in Section 2.01 for the shares of IIC held by
the Stockholder.

         (b) Prior to the Termination  Date, the Stockholder shall not, directly
or indirectly,  except as  contemplated  hereby,  grant any proxies or powers of
attorney with respect to matters set forth in Section  2.01,  deposit any of the
Owned Shares into a voting trust or enter into a voting  agreement  with respect
to any of the Owned Shares, in each case with respect to such matters.

         SECTION 2.03. TRANSFER OF OWNED SHARES BY THE STOCKHOLDER. Prior to the
Termination  Date,  the  Stockholder  shall  not (a)  place  any  lien or  other
encumbrance on any Owned Shares,  other than pursuant to this Agreement,  or (b)
make or  agree  to make  any  sale,  transfer,  pledge,  hypothecation  or other
disposition of any Owned Shares.

SCHEDULE A attached hereto,  the Stockholder has the sole and unencumbered right

individual,  has attained the age of majority  and has legal  capacity,  and the
Stockholder  has  been  duly  authorized  by  all  necessary  action  (including
consultation, approval or other action by or with any other person), to execute,
deliver and perform this Agreement and consummate the transactions  contemplated
hereby.  Such actions by the  Stockholder (a) require no action by or in respect
of, or filing with, any Governmental  Authority with respect to the Stockholder,
other than any required filings under Section 13 of the Exchange Act, and (b) do
not and will not  contravene  or constitute a default  under,  or give rise to a
right of termination, cancellation or acceleration of any right or obligation of
the  Stockholder  or to a loss of any  benefit  of the  Stockholder  under,  any
provision of  applicable  law or regulation  or any  agreement  (including  this
Agreement),  judgment,  injunction, order, decree or other instrument binding on
the  Stockholder  or  result in the  imposition  of any lien on any asset of the
Stockholder or any of its  affiliates  (other than as provided in this Agreement
with respect to IIC Common Shares held by the Stockholder).

         SECTION 3.03. BINDING EFFECT. This Agreement has been duly executed and
delivered  by the  Stockholder  and is the valid and  binding  agreement  of the

other  similar laws  relating to  creditors'  rights  generally and by equitable



                                       3

similar forms of relief are subject.

securities of IIC and has no other  interest in or voting rights with respect to
any other  securities  of IIC. No third party has an option to acquire the Owned
Shares.

         SECTION  3.05.  FINDER'S  FEES.  Except as  disclosed  in the  Purchase
Agreement, no investment banker, broker or finder is entitled to a commission or

Agreement,  including (a) the obtaining of all necessary actions or non-actions,
waivers,  consents and approvals from Governmental Authorities and the making of

waiver from, or to avoid an action or proceeding by, any Governmental Authority,

parties,  (c) the defending of any lawsuits or other legal proceedings,  whether
judicial or administrative, challenging the Purchase Agreement or this Agreement

Agreement and this  Agreement,  including  seeking to have any stay or temporary

                               COVENANTS OF FOCUS

         Focus represents, warrants and covenants to the Stockholder that:

         SECTION 4.01.  CORPORATE  POWER AND AUTHORITY.  Focus has all requisite
corporate  power and  authority to enter into this  Agreement and to perform its

                                       4
<PAGE>

         SECTION 4.02. BINDING EFFECT. This Agreement has been duly executed and
delivered by Focus and is a valid and binding  agreement  of Focus,  enforceable
against Focus in accordance with its terms, except as enforcement may be limited
by  bankruptcy,  insolvency,  moratorium  or  other  similar  laws  relating  to
creditors' rights generally and by equitable principles to which the remedies of
specific performance and injunctive and similar forms of relief are subject.



                                    ARTICLE V

                                  MISCELLANEOUS

         SECTION  5.01.   CONFIDENTIALITY.   The  Stockholder   recognizes  that
successful  consummation of the transactions  contemplated by this Agreement may
be  dependent  upon  confidentiality  with  respect to the  matters  referred to
herein. In this connection,  pending public disclosure thereof,  the Stockholder
agrees that it shall not  disclose  or discuss  such  matters  with anyone not a
party to this  Agreement  (other than its counsel and advisors,  if any) without
the prior written consent of Focus,  except for filings required pursuant to the
Exchange  Act  and  the  rules  and   regulations   thereunder  or   disclosures
Stockholder's  counsel advises are necessary in order to fulfill its obligations
imposed  by law,  in which  event  the  Stockholder  shall  give  notice of such
disclosure  to Focus as promptly as  practicable,  and in any event prior to the
time any such filing or disclosure is made.

         SECTION 5.02.  EXPENSES.  All costs and expenses incurred in connection
with this Agreement shall be paid by the party incurring such cost or expense.

         SECTION 5.03. FURTHER ASSURANCES.  From time to time, at the request of
Focus, in the case of the Stockholder,  or at the request of the Stockholder, in
the case of Focus, and without further  consideration,  each party shall execute
and deliver or cause to be executed and delivered such additional  documents and
instruments and take all such further action as may be necessary or desirable to
consummate the transactions contemplated by this Agreement.

         SECTION 5.04. STOP TRANSFER.  The Stockholder  agrees that it shall not
request that IIC or any other person  register  the transfer (by  book-entry  or
otherwise) of any certificate or uncertificated interest representing any of the
Stockholder's Owned Shares, unless such transfer is made in compliance with this
Agreement  and unless the  transferee  agrees in writing,  in form and substance
satisfactory to Focus,  to be bound by the provisions  hereof for the benefit of
Focus.  In the event of a stock dividend or  distribution,  or any change in the
IIC Common Shares by reason of any stock dividend,  split-up,  recapitalization,
combination, exchange of shares or the like, the term "Owned Shares" shall refer
to and  include  such  Owned  Shares  as well as all such  stock  dividends  and
distributions  and any IIC Common  Shares  into which or for which any or all of
such Owned Shares may be changed or exchanged.

         SECTION 5.05. SPECIFIC  PERFORMANCE.  The Stockholder agrees that Focus
would be irreparably  damaged if for any reason the Stockholder fails to perform
any of the Stockholder's  obligations under this Agreement, and that Focus would
not have an adequate remedy at law



                                       5
<PAGE>

for money  damages in such event.  Accordingly,  Focus shall be entitled to seek
specific  performance and injunctive and other  equitable  relief to enforce the
performance  of this  Agreement by the  Stockholder.  This  provision is without
prejudice to any other rights that Focus may have  against the  Stockholder  for
any failure to perform its obligations under this Agreement.

         SECTION  5.06.  AMENDMENTS;  TERMINATION.  This  Agreement  may  not be
modified,  amended,  altered or  supplemented,  except  upon the  execution  and
delivery  of  a  written   agreement   executed  by  the  parties  hereto.   The
representations,  warranties,  covenants and agreements set forth in Article II,
Sections  3.01 and 3.06 and Article IV shall  terminate,  except with respect to
liability  for prior  breaches  thereof,  upon the  termination  of the Purchase
Agreement  in  accordance  with its terms or, if  earlier,  upon the Closing (as
defined in the Purchase Agreement) (the "Termination Date").

         SECTION 5.07.  SUCCESSORS AND ASSIGNS. The provisions of this Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective estates, heirs, successors and permitted assigns; provided,  however,
that a party may not assign,  delegate or otherwise transfer any of such party's
rights or  obligations  under this  Agreement  without  the consent of the other
parties hereto and any purported assignment, delegation or transfer without such
consent shall be null and void.

         SECTION  5.08.   CERTAIN  EVENTS.  The  Stockholder  agrees  that  this
Agreement and the  obligations  hereunder  shall attach to the IIC Common Shares
Beneficially  Owned by the  Stockholder  and shall be binding upon any person to
which  legal or  Beneficial  Ownership  of such shares  shall  pass,  whether by
operation of law or otherwise.

         SECTION 5.09. ENTIRE AGREEMENT.  This Agreement  constitutes the entire
agreement  among the  parties  with  respect to the  subject  matter  hereof and
supersedes all other prior agreements and understandings, both written and oral,
among the parties with respect to the subject matter hereof.

         SECTION 5.10. NOTICES. All notices, requests, claims, demands and other
communications  hereunder  shall be in writing and shall be deemed  given (a) on
the first business day following the date received,  if delivered  personally or
