ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

          On April 6, 1999, CyberOptics Corporation (the "Company") completed
the acquisition of all of the outstanding shares of Kestra Limited, a British
limited liability company organized under the Companies Act 1985 ("Kestra").
Total consideration of $9,040,012, included $7,942,835 paid in cash by the
Company to shareholders of Kestra at closing, $407,882 paid into an escrow to
cover various warranties, and $689,295 paid by delivery to certain shareholders
of Kestra of the Company's guaranteed notes. The Company also repaid certain
indebtedness of Kestra to the 3i Group PLC, one of Kestra's shareholders, and
certain other obligations related to the shares acquired totaling $2,363,627.

          The Company intends to continue to operate Kestra as a separate
subsidiary in Great Britain. Kestra is a development-stage company that is
developing new technology for automated optical inspection (AOI) systems. The
Company believes that Kestra is developing a fundamentally new approach to AOI
that has the potential to provide the low rates of false calls, the
user-friendliness and the measurement precision demanded by customers in the
surface mount technology industry. Unlike existing AOI systems which use rigid
pattern-matching algorithms, the products under development by Kestra are based
on statistical appearance modeling: a system that can learn how to recognize any
object. As a result of this approach, the Company believes that the Kestra
system will be easy to program, and that its discrimination should improve as
the system is used. Kestra has not sold any product to date, and plans to
complete its first system during the second half of 1999

          Forward looking statements in this Form 8-K with respect to product
introduction dates, the performance of unfinished products, the accounting
treatment of acquired in-process research and development expense, and the
Company's earnings are subject to risks and uncertainties, including risks
related to the ability to continue development efforts of a new subsidiary after
acquisition, risks of code inaccuracies and incompatibilities in software
intensive products, risks of market acceptance, risks related to the SEC's
announced scrutiny of acquired in-process R & D expense, and the general risks
regarding the Company's performance identified in the Company's Annual Report on
Form 10-K.

          a)      Financial statements of the business acquired.

         ("the Notice Date") then any specific amount or amounts claimed under
         an issued writ ("the Initial Claim Amount" or "the Final Claim Amount"
         if different) shall be retained in the Retention Fund (subject to
         clause 5.2.5) until the matter in respect of which the writ was issued
         has been Settled PROVIDED THAT in the event that such a writ is issued,
         but no statement of claim is filed on or before the date six months
         after the Escrow Release Date, then the specific amounts claimed under
         the writ issued shall be released to such of the Warrantors as are
         entitled thereto in accordance with CLAUSE 5.2.3 but such release of
         funds in the Joint Account shall be without prejudice to the
         Purchaser's rights against the Warrantors for breach of any of the
         Warranties;

5.2.5    If within 21 Business Days of the Notice Date (i) the Warrantors
         Representative has given written notice to the Purchaser that the
         Initial Claim Amount is not acceptable to the Warrantors (the
         "Warrantor Notification Date") and (ii) the Warrantors and the
         Purchaser have not agreed a mutually acceptable Initial Claim Amount,
         the Purchaser and the Warrantors shall seek a written opinion (the
         "Opinion") from a mutually acceptable counsel on the amount which he
         considers the Purchaser would be awarded by a competent court in
         respect of such claim (the "Final Claim Amount"). The Opinion shall be
         binding on the Purchaser and Warrantors, in relation to the
         determination of the amount to be retained in the Retention Fund, and
         shall be given by the relevant counsel as an expert and not as an
         arbitrator. The costs and disbursements of such counsel in preparing
         the Opinion shall be borne equally by each of the Warrantors and the
         Purchaser. If no agreement can be reached on a mutually acceptable
         counsel within 14 Business Days of the Warrantor Notification Date in
         accordance with this clause 5.2.5, the matter shall be referred to the
         President of the law Society of England and Wales, on the application
         of either party, who shall appoint a suitably qualified counsel.

5.2.6    a Claim shall be regarded as "Settled" if either:

         (a)      the Warrantors and the Purchaser (or their respective
                  Solicitors) shall so agree in writing, such written agreement
                  not to be unduly withheld or delayed following any oral
                  agreement between the parties; or

         (b)      a Court has awarded judgement in respect of the claim and
                  either no right of appeal lies in respect of such judgement or
                  the parties are debarred whether by passage of time or
                  otherwise from exercising any such right of appeal or the
                  parties in whose favour the right of appeal subsists fails to
                  lodge such appeal within 28 days of such judgement;

5.3      The Warrantors and the Purchaser shall as and when necessary give such
         further instructions to their respective Solicitors as may be required
         in order to procure compliance with CLAUSE 5.2 hereof;

5.4      Where the Purchaser has a Claim which has been Settled (as defined
         above) in its favour then the Purchaser shall be entitled to require
         payment of the full sum due to it from the Warrantors, from the
         Retention Fund and such payment shall be made in accordance with CLAUSE
         5.2.1 without having regard to any individual monetary limitations on
         the Warrantors financial liability.

5.5      In the event that the moneys in the Retention Fund are insufficient to
         pay in full any moneys due to the Purchaser, the Purchaser shall be
         entitled to pursue the Warrantors jointly or severally for the balance
         of the moneys due to it.

5.6      In the event that any sum due to the Company from John Tinning pursuant
         to Clause 5.2. of the Compromise Agreement remains unpaid 30 days after
         the Company has given written notice to John Tinning that such sum is
         due, then the Purchaser shall be entitled to discharge John Tinning's
         liability to the Company (by making a corresponding payment to the
         Company) and recover the amount so paid to the Company out of the
         Retention Fund from the monies contributed to the Retention Fund by
         John Tinning and Dawn Tinning. For the avoidance of doubt nothing in
         this Clause 5.6 shall in anyway increase the total amount of the
         liability which John Tinning would have under Clause 5.2 of the
         Compromise Agreement.

6        COMPLETION

6.1      TIME AND PLACE OF COMPLETION

         Completion shall take place at either the offices of the Purchaser's
         Solicitors or the Seller's Solicitors immediately after signing of this
         Agreement, where the matters set out in SCHEDULE 5 shall apply.

         5.1, the Purchaser shall, without prejudice to any other rights or
         remedies which it may have, be entitled to:

6.2.1    defer Completion with respect to some or all of the Shares to a date
         not more than 28 days after that date (in which case the provisions of
         this CLAUSE 6.2 shall also apply to Completion as so deferred); or

7.4      The Sellers agree with the Purchaser (for itself and as trustee for

         respect of the Contribution Agreement) any present or former director,
         employee or agent of any Group Company in connection with any
         representation, warranty, agreement or statement by any such person in
         relation to this Agreement and any other document to be executed in
         connection with it.

7.5      Each of the Warranties shall be construed as a separate and independent
         provision.

7.6      Save in the event of fraud none of the parties shall be entitled to
         rescind the Agreement after Completion.

7.7      Save as otherwise provided in this Agreement, no claim in respect of or
         arising out of the Warranties or any other provision of this Agreement
         shall be limited or otherwise affected and no amount recoverable in
         respect of any breach shall be reduced by any knowledge (actual or
         constructive) which the Purchaser has or is deemed to have in relation
         to any Group Company.

         necessary for it to enter into and perform its obligations under this

         the execution, delivery and performance of this Agreement, the Tax Deed
         (subject to completion taking place) by it under or pursuant to this
         Agreement and all the same to, or will when executed, constitute

         borrowing of any kind or of any security instrument issued or granted
         by the Purchaser;

7.9      The liabilities of the Warrantors hereunder shall be limited in
         accordance with the provisions of Clause 8;

7.10     The Purchaser confirms to the Warrantors, that having made reasonable
         enquiry of the Project Team only, it is not actually aware of any
         matter which would at the date of this Agreement give rise to an actual
         Claim.

8        WARRANTY LIMITATIONS

8.1      MAXIMUM AMOUNT OF LIABILITY

8.1.1    The aggregate liability of the Warrantors (save in relation to John
         Tinning) for all Claims shall be limited to the aggregate consideration
         received by such Warrantors (other than MTD) and each of the Related
         Persons and MTD (in respect of the sale of its Ordinary Shares only)
         pursuant to this Agreement. John Tinning shall only be liable in
         relation to a Claim for an amount up to the consideration received by
         him and Dawn Tinning as set out opposite their names in Schedule 1.

8.1.2    Where the Trustees of the Pension Fund of Victoria University are
         trustees and are selling shares in such capacity, then their respective
         aggregate liability in respect of all claims under this Agreement shall
         be limited (so far as such liability would otherwise arise in
         consequence of the sale of such shares) to the amount of the relevant
         trust fund or estate for the time being


                                       23
<PAGE>


         in their hands and available to them to satisfy such liability. The
         Trustees shall be discharged from all liability under this Agreement if
         any continuing trustee or personal representative appointed in their
         place has entered or enters into a direct covenant with the Purchaser
         may reasonably require to be bound by an observe and perform the terms
         of this Agreement.

8.2      MINIMUM AMOUNT OF LIABILITY

         The Warrantors shall not have to make a payment in respect of a Claim
         unless the aggregate liability in respect of such Claim (when
         aggregated with the Warrantors' liability in respect of all other
         Claims made by the Purchaser or which would have been made but for the
         provisions of this Clause 8.2) (but excluding related interest and
         costs) in respect of all Claims exceeds (pound)50,000, provided that if
         such aggregate liability exceeds that amount, then the Warrantors shall
         be liable for the whole of the liability and not just the excess of
         such aggregate liability above the sum of (pound)50,000.

8.3      TIME LIMITS

         No claim shall be made against the Warrantors unless notice in writing
         is given to the Sellers' Representative by the Purchaser (giving
         reasonable details (having regard to information available to Purchaser
         at the time when the notice is given) of the specific matter in respect
         of which such Claim is made):-

8.3.1    on or before 31 December 2001 in respect of a Warranty Claim (other
         than in respect of a Warranty Claim relating to Taxation); or

8.3.2    on or before the date falling 6 years after the end of the current
         accounting period of the Company in respect of a Warranty Claim
         relating to Taxation or a Tax Deed Claim and in each case unless legal
         proceedings in respect of such Claim are commenced and served upon the
         Warrantors within nine months after such written particulars have been
         given to the Warrantors;

         or if a Claim is contingent, then if later within nine months after
         such Claim ceases to be contingent.

8.4      EXCLUSION OF CLAIMS

         The Warrantors shall have no liability in respect of any Warranty Claim
         to the extent arising from any matter, act, omission or circumstance
         Disclosed in the Disclosure Letter or in the documents annexed to it.
         For the avoidance of doubt, nothing in the Disclosure Letter shall, or
         shall be deemed to, be disclosed against warranty 2.4 of Part 1 of
         Schedule 4.

8.5      NON-APPLICABILITY IN THE EVENT OF FRAUD


                                       24
<PAGE>


         The exclusions and limitations set out in this CLAUSE 8 shall not apply
         in relation to Claims which are the consequence of fraud, or wilful
         concealment by the Sellers.

8.6      None of the limitations set out in this CLAUSE 8 shall apply in respect
         of any Claim by the Purchaser for breach of the Share Ownership
         Warranties.

8.7      The Warrantors shall have no liability in respect of any Warranty Claim
         relating to any matter to the extent that the Accounts or Management
         Accounts make a specific provision or reserve for the matter giving
         rise to the Warranty Claim.

8.8      Where the same fact or circumstances could give rise to more than one
         Warranty Claim or a Tax Deed Claim, the Purchaser shall not be entitled
         to recover more than once for the same loss, so that, in calculating
         the amount payable for breach of any of the Warranties or in respect of
         the Tax Deed account shall be taken of any amount paid under the other
         Warranties, or in respect of a Tax Deed Claim in respect of the same
         facts or circumstances.

8.9      The Warrantors shall not be liable in respect of any Warranty Claim if
         and to the extent that:

         (a)      such breach or Claim occurs or increases as a result of the
                  passing of, or changing, after the date of this Agreement, any
                  legislation with retrospective effect; or

         (b)      such liability would not have arisen but for a change after
                  Completion in the Accounting Policies used in the Accounts
                  PROVIDED THAT this limitation shall not apply where such
                  change is necessary to conform with UK generally accepted
                  accounting policies; or

         (c)      such liability would not have arisen but for the voluntary act
                  or omission of the Purchaser after Completion which (i) is
                  outside the ordinary course of trade of the Group as carried
                  on at Completion (and is not required pursuant to a legally
                  binding commitment entered into prior to Completion or any
                  requirement of law); and (ii) which the Purchaser actually
                  knew or on the basis of the information Disclosed ought
                  reasonably to have known would rise to a Warranty Claim;

         (d)      to the extent that it relates to any loss for which the
                  Purchaser or any Group Company (as the case may be) actually
                  recovered from an insurer;

         (e)      which would not have arisen but for anything expressly done or
                  provided to be done or omitted to be done pursuant to this
                  Agreement or which is otherwise done or omitted to be done at
                  the specific written request or with the written consent of
                  the Purchaser provided that the Purchaser should on the basis
                  of information Disclosed, have been aware that this would (or
                  would be likely to) have arisen;


                                       25
<PAGE>


         (f)      to the extent that it relates to the Intellectual Property
                  except only for such Claim as the Purchaser may have in
                  consequence of any breach by the Warrantors of the Warranty
                  contained in paragraphs 2.2, 10.3, 11 or 13 of Part 1 of
                  Schedule 4;

8.10     Notwithstanding the provisions of this Agreement, the Warrantors shall
         not be liable in respect of any Warranty Claim arising under the
         Warranties at Part 2 of Schedule 4 to this Agreement to the extent
         provided in paragraphs 4.1.1 to 4.1.14 inclusive of the Tax Deed.

8.11     In relation to any Warranty Claim, and without prejudice to the
         validity of the Warranty Claim, the Purchaser shall allow the
         Warrantors and their professional advisers (at the Warrantors' own
         cost) to investigate the matter or circumstance alleged to give rise to
         the Warranty Claim and the Purchaser shall at the request and cost of
         the Warrantors give such assistance as the Warrantors or their
         professional advisers may reasonably request for the purposes of such
         investigation, including upon reasonable notice and in normal business
         hours, access to and copies of any documents or other information in
         the possession of the Purchaser and (at reasonable times and upon
         reasonable notice) to enable the Sellers and/or their professional
         advisers to interview relevant personnel PROVIDED ALWAYS THAT any such
         rights of access and/or copying of documentation shall be limited to
         information concerning the Warranty Claim and shall not, for the
         avoidance of doubt, extend to any access to personnel, information or
         documentation the subject of legal or other privilege or which would
         otherwise not be subject to the Rules of the Supreme Court in respect
         of discovery.

8.12     Any amount recovered by the Purchaser from the Warrantors pursuant to
         Claim shall be treated as a reduction in the price received by the
         Warrantors for the Shares held by them and/or as a reduction received
         in consideration of giving the Warranties or covenants given by them as
         the case may be.

8.13     CONTINGENT CLAIMS

         The Warrantors shall not be liable for any Claim to the extent that it
         relates to a Claim based on a contingency until the contingency has
         become actual save that such a Claim, if made as a contingent claim
         prior to the expiry date of the relevant time limited contained in
         Clause 8.3, shall survive until the earlier of the date upon which the
         contingency becomes actual and the seventh anniversary of Completion.

8.14     RECOVERY AGAINST THIRD PARTIES

         If the Warrantors have paid to the Purchaser any amount in respect of a
         Warranty Claim and the Company or the Purchaser subsequently receives
         or recovers from a third party (including an insurer) a sum which is
         directly referable to such Warranty Claim, the Purchaser shall, as soon
         as reasonably practicable following such recovery, repay to the
         Warrantors as have made such payment to the Purchaser the lesser of the
         amount received from that Warrantor and the


                                       26
<PAGE>


         amount received from the third party in respect of such Warranty Claim,
         in each case less all reasonable costs incurred by the Purchaser in
         making such recovery.

8.15     CONDUCT OF WARRANTY CLAIMS

8.15.1   If the Purchaser receives notice of a claim by a third party ("Third
         Party Claim") against the Company, the Subsidiary or the Purchaser
         which constitutes or which the party obtaining notice of such matter,
         fact or circumstance ought reasonably to have known is likely to give
         rise to a Warranty Claim on the basis of information Disclosed the
         party receiving such notice shall notify the other(s) as soon as
         reasonably practicable, and not make any admission of liability,
         agreement or compromise in respect of such claim, without consultation
         with the other parties and the Purchaser shall, subject to the
         indemnity referred to in CLAUSE 8.15.2 below take all such steps as the
         Warrantors' Representative may reasonably require to resist, defend or
         otherwise compromise such Third Party Claim(including the appointment
         of solicitors nominated by the Warrantors) PROVIDED ALWAYS nothing in
         this CLAUSE 8.15.1 shall require the Purchaser to take or omit to take
         any action which, in the case of a, b or c below, following an opinion
         of Counsel (as set forth in this clause), is deemed to be or have (as
         appropriate):

         (a)      frivolous;
         (b)      vexatious;
         (c)      on the balance of probabilities has less than a 50% change of
                  success; or
         (d)      in the Purchaser's reasonable opinion, would or would be
                  likely to prejudice or materially interfere with the carrying
                  on of the business of the Group or prejudice or materially
                  interfere with the Group or the Purchaser's relationship with
                  any tax authority;

         by reference in (a), (b) or (c) above, to an opinion obtained from a
         reputable Counsel of not less than five years standing practicing in
         London. In obtaining such opinion the Warrantors Representative and the
         Purchaser shall agree upon the identity of the barrister to be
         instructed (or in default of agreement to be appointed by the President
         of the Bar Council of England and Wales) and shall in addition agree
         upon the instructions to be provided.

8.15.2   The Warrantors shall indemnify and keep indemnified the Purchaser
         against and in respect of all costs incurred, charges, expenses,
         liabilities and damages for which the Purchaser or the relevant member
         of the Purchaser's Group becomes liable in respect of any action which
         is required to be taken by the Warrantors (or any of them) under CLAUSE
         8.15.1.

8.15.3   The Purchaser shall keep the Warrantors' Representative informed of the
         progress and the defence of any Third Party Claim and shall consult
         with and (subject always to the proviso in CLAUSE 8.15.1 above) shall
         take such action as the Warrantors' Representative may reasonably

                                 VUMAN GUARANTEE


1        Guaranteed Obligations

         first demand by the Purchaser)following a failure by MTD to comply with
         a demand by the Purchaser to do so, immediately perform and discharge
         the obligations of MTD under those provisions.

2        Guarantee Continuing and Additional to Any Other Rights

         The guarantee set out in Paragraph 1 (Guaranteed Obligations):

         (a)      is a continuing guarantee and shall remain in force and effect
                  until MTD has performed and discharged all of its obligations
                  under this Agreement; and

         (b)      is additional to (and not in substitution for) any other
                  security or guarantee which is or may be held by the Purchaser
                  from time to time in respect of the obligations of MTD under
                  this Agreement save that, prior to the Escrow Release Date, no
                  claim shall be made on the Guarantor until such time as the
                  funds held in the Joint Account have been exhausted.

3        Liability

         The Guarantor's liability under Paragraph 1 (Guaranteed Obligations)
         shall not be affected by any concession, time, indulgence or release
         granted by the Purchaser to MTD or any other person or by any payment
         or other dealing or anything else which would, but for this Paragraph 3
         operate to discharge or reduce that liability.

4        Primary Obligor

         If anything (including any legal limitation, disability, liquidation or
         other incapacity on the part of MTD) or any disclaimer by a liquidator
         or trustee in bankruptcy causes any of MTD's obligations under this
         Agreement and/or the guarantee set out in Paragraphs 1 (Guaranteed
         Obligations) to be or become invalid or unenforceable, then the
         Guarantor shall perform and discharge all of MTD's obligations under
         this Agreement as if they were the primary obligations of the
         Guarantor.

5        No Deduction or Withholding

         The Guarantor shall make any payments due from it under this Schedule 7
         in full, without any deduction or withholding in respect of any claim

         matter or thing.

<PAGE>


6        Postponement of the Guarantor's Ability to Exercise Rights

         The Guarantor shall not exercise any rights which it may have against
         MTD arising from or otherwise relating to its guarantee under Paragraph
         1 (Guaranteed Obligations) or its other obligations under this Schedule
         7 unless and until all of the obligations of MTD and the Guarantor
         under this Agreement have been performed and discharged.

7        Enforcement

         The Purchaser may only claim under the guarantee set out in Paragraph 1
         (Guaranteed Obligations) after first making demand of MTD but is not
         required to take any action to claim under or enforce any other right,
         security or other guarantee which it may hold from time to time in
         respect of the other parties' obligations under this Agreement.

8        Obligations Unconditional and Irrevocable

         The Guarantor's obligations under this Clause, including its guarantee
         under Paragraph 2 (Guaranteed Obligations), are unconditional and
         irrevocable, but for the avoidance of doubt cease at such time as the
         obligations of MTD under the Agreement cease and shall not give rise to
         any greater liability to the Guarantor than the liability where MTD has
         under the Agreement.

         respective meanings in this deed as they have in such legislation
         (unless the context otherwise requires).

         requires, a reference to:

2.7.1    a person is to be construed to include a reference to any individual,

         to any orders, regulations, instruments or other subordinate
         legislation (and relevant codes of practice) made under the relevant
         statute except to the extent that any amendment, consolidation, or
         re-enactment coming into force after the date of this deed would
         increase or extend the liability of any party to this deed to any other
         party.

2.8      In this deed, unless otherwise specified, the rule of construction
         known as the 'ejusdem generis rule' shall not apply so that words or
         phrases of a generally descriptive nature shall not be given a
         restrictive meaning by reason only of the fact that they are preceded
         by more specific words or phrases and words of a generally descriptive
         nature shall not be given a restrictive meaning by reason only of the
         fact that they are followed by specific examples.

         3.1.1.1  any Event occurring on or before Completion;

         3.1.1.2  any income, profits or gains which accrued, or which were
                  earned or received, on or before Completion or in respect of a
                  period ending on or before Completion; or

         3.1.1.3  any dividend or other distribution made by a Group Company
                  before Completion; or

         in each case whether or not such Liability to Tax is also chargeable
         against or attributable to any other person; and

3.1.2    to pay to the Purchaser within 7 days from written notice by the
         Purchaser amounts equal to any reasonable costs and expenses reasonably
         incurred by the Purchaser or the Group Company in connection with any
         Liability to Tax as referred to in clause 3.1.1 or any Claim or in
         taking or defending any successful action pursuant to this deed.

3.2      Each of the covenants contained in clauses 3.1.1.1, 3.1.1.2 and 3.1.1.3
         shall be construed as giving rise to separate and independent
         obligations and shall not be restricted by the other save that (for the
         avoidance of doubt) any payment by the Covenantors in respect of a
         liability under one covenant shall discharge any liability under the
         other to the extent of such payment and in so far as it arises from the
         same subject matter.


                                                                              74

4.       LIMITATIONS

4.1      EXCLUSIONS

         The Covenantors shall have no liability in respect of any Claim under
         clause 3.1.1 and 3.1.2 to the extent that:

4.1.1    the Accounts or the Closing Balance Statement make specific provision
         or reserve in respect of such Liability to Tax (not being a provision
         or reserve for deferred tax); or

4.1.2    it arises from the passing of, or change in, after the date of the
         Agreement, any law, regulation, rule or published practice of any
         government, governmental department, agency, regulatory body or Tax
         Authority or any judgment delivered after the date of the Agreement
         with retrospective effect, or any increase in the rates of Taxation or
         any imposition of Taxation not in effect at the date of the Agreement
         or any retrospective withdrawal of a change in after the date of the
         Agreement any practice or extra-statutory concession previously
         published by any Tax Authority; or

4.1.3    such Liability to Tax would not have arisen but for a change after
         Completion in accounting policy or practice or to the accounting
         reference date of a Group Company save where such change complies with,
         or is to comply with, generally accepted accounting practice within the
         United Kingdom.

4.1.4    such liability to Tax was discharged on or before Completion at no
         expense to the Purchaser; or

4.1.5    payment has already been made in respect of such Liability to Tax at no
         expense to the Purchaser; or

4.1.6    such Liability to Tax or other liability would not have arisen but for
         a voluntary act, transaction or omission of the Company and/or
         Subsidiary after Completion:-


                                                                              75
<PAGE>


         4.1.6.1  otherwise than pursuant to a legally binding obligation
                  entered into by the Company and/or subsidiary (as the case may
                  be) on or before Completion or imposed on the Company and/or
                  the Subsidiary by any legislation whether coming into force
                  before, on or after Completion; and

         4.1.6.2  which the Purchaser knew or ought reasonably to have known
                  would give rise to the Liability to Tax; and

         4.1.6.3  otherwise than in the ordinary course of business of the
                  Group; or

4.1.7    such Liability to tax not would have arisen but for the Company and//or
         Subsidiary ceasing to carry on any trade or business after Completion
         or effecting a major change after Completion in the nature or conduct
         of the business as compared to the business carried on by it at
         Completion; or

4.1.8    such Liability to Tax would not have arisen but for the failure by the
         Company and/or Subsidiary after Completion to make any claim, election,
         surrender or disclaimer or to give any notice or consent or to do any
         other thing, the making, giving or doing of which was permitted by law
         and which was taken into account:-

         4.1.8.1  in computing and so reducing any provision for current or
                  deferred Tax which appears in the Accounts (or eliminating any
                  provision for current or deferred Tax which, but for such
                  Relief, would have appeared in the Accounts); or

         4.1.8.2  in computing any right to a repayment of Tax which appears in
                  the Accounts;

         and in the case of either 4.1.8.1 or 4.1.8.2 full details of which are
         included in the Disclosure Letter or appear on the face of the
         Accounts; or

4.1.9    such Liability to Tax would not have arisen but for the withdrawal or
         amendment by the Company and/or the Subsidiary after Completion of any
         claim, election, surrender, disclaimer, notice or consent made by it
         and (where appropriate) agreed with the relevant Tax


                                                                              76
<PAGE>


         authority prior to Completion in relation to any Relief arising in an
         accounting period ending on or before the Accounts Date; or

4.1.10   such Liability to Tax would not have arisen but for any failure or
         delay by the Purchaser or the relevant Group Company in paying over to
         any Tax Authority any payment previously made the Covenantors under
         this Deed; or

4.1.11   such Liability to Tax is a liability of a Group Company to account for
         advance corporation tax which such Group Company is entitled to utilise
         by way of set off against its overall liability to corporation tax in
         respect of the same or any earlier accounting period, or

4.1.12   such Liability to Tax is in respect of the actual earning, receipt or
         accrual for any Tax purposes of any income, profit or gain which is not
         recognised in the Accounts where such income, profit or gain arises in
         relation to the period beginning after the Accounts Date and ending on
         the Completion Date; or

4.1.13   a Relief, other than a Relief referred to in clause 2.2 or arising as a
         result of any Event occurring after Completion, is available to be used
         against the liability in question; or

4.1.14   such Liability to Tax arises from the Payment made by the Company to
         John Tinning under Clause 4 of the Compromise Agreement.

4.2      For the avoidance of doubt, the limitations and stipulations contained
         in clauses 8.1.1, 8.2, 8.3.2, 8.8 and 8.12 of the Agreement shall apply
         mutatis mutandis in respect of any liability or potential liability of
         the Covenantors pursuant to the provisions of this Deed.

5.       CONDUCT OF CLAIMS

5.1      If the Purchaser becomes aware of any Assessment which does or may give
         rise to a Claim the Purchaser shall or shall procure that the relevant
         Group Company will:-


                                                                              77
<PAGE>


5.1.1    give notice in writing of such Assessment including an estimate of the
         amount of the liability to Tax to which the Assessment relates as soon
         as reasonably practicable and, in any event within 14 Business Days
         after the receipt of such Assessment, to the Covenantors provided that
         the giving of such notice shall not be a condition precedent to the
         liability of the Covenantors under this deed;

5.1.2    not settle or take any action in relation to the Assessment without
         first giving the Covenantors the opportunity to dispute, avoid, resist,
         appeal, compromise or contest the Assessment in accordance with
         paragraph 5.2 below; and

5.1.3    at the Covenantors request and expense submit a protective Notice of
         Appeal against the Assessment to the relevant Tax Authority.

5.2      If the Covenantors shall indemnify the relevant Group Company and the
         Purchaser to their reasonable satisfaction against any losses, fines,
         penalties, interest, charges, reasonable costs and expenses, the
         Purchaser shall and shall procure that the Company shall, subject to
         clause 5.3, take such lawful and reasonable action as the Covenantors
         shall reasonably require to avoid, dispute, resist, appeal, compromise
         or contest such Assessment (the "Covenantor's Action"), including
         (subject to clauses 5.3 to 5.8):-

5.2.1    applying to postpone (so far as legally possible) the payment of any
         Tax; and

5.2.2    except in the case of an Assessment where any Tax Authority alleges
         dishonest or fraudulent conduct on the part of the Covenantors or any
         Group Company taking place on or before Completion allowing the
         Covenantors to undertake at the Covenantors' own cost and expense, the
         conduct of any dispute, appeal, negotiation or other proceedings
         relating directly to the Assessment, Provided that:

         5.2.2.1  the Covenantors shall keep the Purchaser and/or the relevant
                  Company fully informed and shall consult with the same in
                  respect thereof; and

         5.2.2.2  no material communication, written or otherwise pertaining to
                  any dispute, appeal, negotiation or other proceedings relating
                  to the Assessment shall be sent to a relevant Tax Authority
                  without first having been submitted to the Purchaser for its
                  written approval such approval not to be unreasonably withheld
                  or delayed.


                                                                              78
<PAGE>


5.3      Neither the Purchaser nor any Group Company shall be obliged to appeal
         against any Assessment if, having given the Covenantor notice of the
         receipt of that Assessment, it has not within 10 Business Days received
         instructions in writing from the Covenantors in accordance with clause
         5.2 to make that appeal.

5.4      Neither the Purchaser nor any Group Company shall be obliged to take
         any action or further action under this clause in respect of any
         Assessment if it reasonably appears to the Purchaser that either the
         Covenantors or the relevant Group Company prior to its being in the
         ownership of the Purchaser, have committed acts or omissions which may
         constitute fraudulent or negligent conduct.

5.5.     Neither the Purchaser nor any Group Company shall be required to take
         any action which would or would be likely materially to interfere with
         or prejudice the carrying on of the business of the Group or interfere
         or prejudice the relationship of the Company and each member of the
         Group with its customers and suppliers or with any Tax Authority;

         In each case, in the event of any dispute, to be determined by
         reference to an opinion obtained from a reputable specialist Tax
         Counsel of not less than 7 years' standing, practising in London. In
         obtaining such opinion the Covenantors Representative and the Purchaser
         shall agree upon the identity of the barrister to be instructed (or in
         default of agreement, to be appointed by the President of the Bar
         Council of England and Wales) and shall, in addition, agree upon the
         instructions to be provided.

5.6      Neither the Purchaser nor any Group Company shall be obliged to take
         any action under this clause 5 which involves contesting any Assessment
         before any court or other appellate body (excluding the Tax Authority
         demanding the Tax in question) unless an opinion has been obtained
         pursuant to Clause 5.5 to the effect that an appeal against the
         Assessment in question will, on the balance of probabilities, be won

5.7      The Purchaser and any Group Company shall be at liberty without
         reference to the Covenantors to acting reasonably admit, compromise,
         settle, discharge or otherwise deal with any Assessment after whichever
         is the earliest of:

5.7.1    the Purchaser or the relevant Group Company being notified by the
         Covenantors that it considers the Assessment should no longer be
         resisted;


                                                                              79
<PAGE>


5.7.2    the expiry of a period of 10 days following the service of a notice
         explaining the consequences of this clause 5.7 by the Purchaser or the
         relevant Group Company on the Covenantors requiring the Covenantors to
         clarify or explain the terms of any request made under clause 5.2
         during which period no such clarification or explanation has been
         received by the Purchaser or the relevant Group Company; and

5.7.3    if appropriate, the expiration of any period prescribed by applicable
         legislation for the making of an appeal against either the Assessment
         or the decision of any court or tribunal in respect of any such
         Assessment, as the case may be.

5.8      The Covenantors shall be bound to accept for the purposes of this deed
         any admission, compromise, settlement or discharge of any Assessment
         and the outcome of any proceedings relating to it made or arrived at in
         accordance with the provisions of this clause 5.

6.       DUE DATE FOR PAYMENT

6.1      Where the Covenantors become liable to make any payment pursuant to
         CLAUSE 3, the due date for the making of that payment shall be:

6.1.1    in a case that involves an actual payment of Tax by a Group Company,
         the date that is 3 Business Days immediately before the last date on
         which the relevant Group Company would have had to have paid to the
         relevant Tax Authority the Tax that has given rise to the Covenantors
         liability under this deed in order to avoid incurring a liability to
         interest or a charge or penalty in respect of that Liability to Tax
         ("the payment date") and (unless it is apparent from the correspondence
         between the parties) the Purchaser or relevant Group Company shall
         notify the Covenantors of the payment date in sufficient time to allow
         the Covenantors to make a payment to the Purchaser 3 Business Days
         before such payment date; or


                                                                              80
<PAGE>


6.1.2    in a case falling within clause 2.2 the date falling 5 Business Days
         after the date on which the Covenantors have been notified by the
         Purchaser that the auditors for the time being of the Group have
         certified, at the request of the Purchaser, that there is liability for
         a determinable amount under CLAUSE 2.3.

6.2      If any payment required to be made to the Purchaser or to the
         Covenantors under this deed is not made by the due date then, that
         payment shall carry interest from (and including) that due date until
         (but excluding) the date when the payment is actually made at the rate
         of 4 per cent above the base rate from time to time of Barclays Bank
         PLC.

7.       DEDUCTIONS FROM PAYMENTS

7.1      All sums payable by the Covenantors to the Purchaser under this deed
         shall be paid free and clear of all deductions or withholdings
         whatsoever, save only as may be required by law.

7.2      If any deduction or withholding in respect of Tax or otherwise is
         required by law to be made from any of the sums payable as mentioned in
         clause 7.1, the Covenantors shall be obliged to pay to the Purchaser
         such greater sum as will, after such deduction or withholding as is
         required to be made has been made (taking into account any Relief which
         is or will be received by the Purchaser by reason of such deduction or
         withholding), leave the Purchaser with the same amount as it would have
         been entitled to receive in the absence of any such requirement to make
         a deduction or withholding.

7.3      All sums payable by the Covenantors under this deed are to be paid in
         the currency or currencies appropriate to the Assessment as a result of
         which the liability to make a payment of Tax has arisen.

7.4      The Purchaser may direct the Covenantor to pay to any Group Company any
         sums due to the Purchaser under this deed and such payment shall be
         treated as a payment to the Purchaser and not a payment to the relevant
         Group Company.

7.5      In the event of an assignment by the Purchaser of the terms of this
         Deed pursuant to clause 12.4, the Covenantors shall not be required to
         pay to any such assignee a greater sum than they would have been
         obliged to pay to the Purchaser by virtue of clause 7.2, had such
         assignment not taken place.


                                                                              81
<PAGE>


8.       MITIGATION

         Subject to the express provisions of this deed, neither the Purchaser
         nor any Group Company shall be under any obligation or duty to mitigate
         any loss or take any other action to reduce the Covenantor's liability
         under this deed.

9.       PURCHASER'S COVENANTS

9.1      The Purchaser covenants with the Covenantors to pay to the Covenantors
         an amount equal to any liability to Tax assessed upon the Covenantors
         under section 767A or 767AA ICTA in connection with any event,
         transaction, omission or occurrence occurring in the accounting period
         of the Company current at Completion or in any earlier account period
         and arising as a result of the Company failing to discharge such
         liability together with any reasonable costs, fees or expenses incurred
         by the Covenantors in connection with such liability.

9.2      The Purchaser will be entitled to set off against any amount which it
         is liable to pay to the Covenantors under paragraph 9.1 (or any amount
         which it is liable to pay under section 767B ICTA 1988 should the
         Covenantors have to enforce their entitlement to payment under that
         section) any amount which the Covenantors are liable to pay the
         Purchaser under this Deed (ignoring for this purpose the financial
         limits in clauses 8.1 and 8.2 of the Agreement).

9.3      To the extent that a payment is made by the Purchaser to the
         Covenantors pursuant to paragraph 12.1, the Covenantors will not
         enforce its entitlement to payment of any amount under section 767B (2)
         ICTA 1988.

10.      GENERAL

10.1     All payments by the Covenantors under this Deed will be treated as
         repayments by the Covenantors of the consideration paid for the Shares
         to this Agreement, provided that this paragraph 10.1 will not operate
         in any way to limit the liability of the Covenantors under this Deed.


                                                                              82
<PAGE>


11.      REPAYMENTS

11.1     If at the Covenantors' request and expense, the Auditors determine and
         certify that any Group Company has obtained a repayment of Tax where
         the Covenantors have made a payment under this Deed in respect of the
         same Tax which is the subject of the repayment ("Repayment"), or that
         any Tax liability which has resulted in a payment being made by the
         Covenantors has given rise to a saving for a Group Company
         ("Saving"),the Repayment or Saving will be applied as follows:-

11.1.1   first, the amount of the Repayment or Saving will be set off against
         any payment then due from the Covenantors under this Deed;

11.1.2   secondly, to the extent that there is an excess, the Purchaser will,
         within 10 Business Days pay to the Covenantors the lesser of:-

         11.1.2.1 the amount of the excess; and

         11.1.2.2 any amount previously paid by the Covenantors under this Deed;

11.1.3   thirdly, to the extent that the excess referred to in paragraph 11.1.2
         is not exhausted, the remainder of that excess will be carried forward
         and set off against any future liability of the Covenantors under this
         Deed;

11.2     The Purchaser will inform the Covenantors as soon as reasonably
         practicable after it or any Group Company becomes aware that any Group
         Company may obtain a Repayment or Saving.

11.3     The relevant Group Company will so far as is reasonable utilise any
         Relief (other than a Relief referred to in clause 2.2 or arising as a
         result of an Event occurring after Completion), which gives rise to a
         Saving or a Repayment in priority to any other Relief (other than a
         Relief referred to in clause 2.2 or arising as a result of an Event
         occurring after Completion), as soon as practicable, unless and to the
         extent that such utilisation would prejudice the availability of any
         other Relief.


                                                                              83
<PAGE>


11.4     In determining whether or not a Group Company has obtained a Saving or
         Repayment and if so, the amount, the Auditors will act as experts and
         not as arbitrators and their determination will (in the absence of
         manifest error) be conclusive and binding on the parties.

                        CYBEROPTICS PURCHASES KESTRA LTD

               NEXT-GENERATION SMT INSPECTION TECHNOLOGY ACQUIRED


APRIL 6, 1999 - MINNEAPOLIS, MN - CyberOptics Corporation (Nasdaq National
Market: CYBE) today announced the acquisition of Kestra Ltd, an emerging,
UK-based company that is developing breakthrough technology for automated
optical inspection (AOI) systems.

Steven K Case, chairman, commented: "The formation of market-focused business
units in early 1998 enabled CyberOptics to better understand the changing needs
of SMT assemblers, who are confronted by a growing array of challenges,
including faster production line speeds, cost pressures and circuit
miniaturization. Given the inherent limitations of current AOI technologies in
such areas as high rates of false calls (mistakes) and difficulty in
programming, we have found SMT producers are looking for new inspection
solutions.

"After evaluating potential companies for over a year," Case continued,
"CyberOptics determined that Kestra is developing a fundamentally new approach
to AOI that has the potential to provide the low rates of false calls, the
user-friendliness and the measurement precision demanded by SMT customers.
Through Kestra, we believe CyberOptics is responding to the complex and changing
needs of our customers."

While existing AOI systems use rigid pattern-matching algorithms, the Kestra
concept is based on statistical appearance modelling that can learn for itself
how to recognise any object. As a result of this approach, the Kestra system
under development should be easy to program, and its discrimination should
improve the more the system is used. It will also allow pass/fail decisions to
be made that are not confused by the variability found in real-world production.

Kestra plans to complete its first system during the second half of 1999.
Intended to provide gauge-level measurement with a low rate of false calls, this
system is expected to be of particular interest to high-volume manufacturers.

The Company acquired all of the stock of Kestra and repaid certain indebtedness
for total consideration of approximately $11.5 million in cash. The Company
expects to incur a significant one-time charge in this year's second quarter
related to in-process R&D acquired from Kestra, which will cause the Company to
post a net loss for this period. Operating losses from Kestra during its
development stage and early introduction period will affect the Company's second
half operating results, but in the absence of the Kestra transaction, the
Company expects to be profitable for all of 1999.

CyberOptics is a leading supplier of non-contact process control sensors and
inspection systems that improve the yields and operating efficiencies of
production lines that assemble SMT circuit boards.

Statements regarding the Company's anticipated performance in 1999 are
forward-looking and therefore involve risks and uncertainties, including but not
limited to, risks related to the current scrutiny by regulatory bodies
(including particularly the SEC) of accounting treatment of in-process R&D, the
Company's dependence on OEM customers, market conditions in the global
electronics industry, the high proportion of the Company's sales which are made
outside the US, the sensitivity of the Company's sales to changing technologies,
and other factors set forth in the Company's filings with the Securities and
Exchange Commission
