         Item 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On June 21, 1995, the Registrant consummated the acquisition of
substantially all of the assets of York Technology Limited, a company
incorporated in England ("York Tech England"), and York Technology Inc. , a New
Jersey corporation ("York Tech USA"), as well as the real estate and building
previously leased by York Tech England (the "York Tech Building"). The total
purchase price (exclusive of closing costs) for all of these assets was
approximately $6,700,000.

         Cornibi Limited, a company incorporated in England and a subsidiary
formed by the Registrant for purposes of the York Tech England acquisition
("Cornibi"), acquired substantially all of the assets of York Tech England
pursuant to the terms of an Agreement for the purchase of the business of York
Technology Limited dated June 21, 1995 by and among York Limited, the parent
company of York Tech England, York Tech England, Cornibi Limited, and the
Registrant, as amended by supplemental agreement dated June 29, 1995 (as
amended, the "York Tech England Acquisition Agreement"). Under the terms of the
York Tech England Acquisition Agreement, Cornibi acquired substantially all of
the assets of York Tech England for a total purchase price of $4,071,000,
payable with a note in the principal amount of $1,872,000 (the "Term Note") and
with the balance paid in cash at closing. The balance of the Term Note, without
interest, is to be paid on December 31, 1996, and may, at the option of Cornibi,
be paid with shares of the Registrant's common stock based on the average market
price of the Registrant's common stock for the twenty trading days ending the
business day prior to the date of delivery of the shares in full or partial
payment of the Term Note. Contemporaneously with the closing of the York Tech
England Acquisition Agreement, Cornibi also purchased the York Tech Building
from TKM Group Pension Trust Limited("TKM") for 700,000 British pounds or
$1,123,000 pursuant to the terms and conditions of a Freehold Agreement dated
June 21, 1995 by and between TKM and Cornibi (the "York Tech Building
contract").

         At the same time as the closing of the York Tech England Acquisition
Agreement and the York Tech Building Contract, Photon Kinetics, Inc., an Oregon
corporation and wholly-owned subsidiary of Registrant ("PK"), acquired
substantially all of the assets of York Tech USA pursuant to the terms of an
Agreement for the purchase of the business of York Technology Inc. dated June
21, 1995 by and among York Limited, the English parent company of York Tech USA,
York Tech USA, PK, and the Registrant (the "York Tech USA Acquisition
Agreement"). Under the terms of the York Tech USA Acquisition Agreement, PK
acquired substantially all of the assets of York Tech USA for a total purchase
price of $1,550,907, payable in cash at closing.

                                     Page 2


<PAGE>


         York Tech England and York Tech USA designed, manufactured, and sold
fiber optic test and measurement equipment primarily for the fiber production
and preparation market. Registrant currently intends for Cornibi to continue the
business of York Tech England and for PK to continue the business of York Tech
USA.

         The purchase prices for York Tech England and York Tech USA
transactions were determined by arms-length negotiations between representatives
of the Registrant and York Limited. The purchase price for the York Tech
Building was determined by arms-length negotiation between representatives of
the Registrant and TKM. With the exception of the Term Note, Registrant's
source of funds for the acquisitions was a combination of cash reserves and
cash from existing credit facilities.

         The foregoing summary of the acquisition of substantially all of the
assets of York Tech England and York Tech USA as well as the York Tech Building
is qualified in its entirety by reference to the York Tech England Acquisition
Agreement, the York Tech USA Acquisition Agreement, and the York Tech Building
Contract, copies of which are exhibits hereto and are incorporated herein by
reference.

(US$1,550,907.00), which shall be apportioned among the Assets as follows:

                                      - 8 -

                 (b)   Goodwill                   US$        1

                 (c)   Knowhow                    US$  878,249

                 (d)   Plant and Equipment        US$   37,734

                 (e)   Inventory                  US$  634,922
                       (subject to adjustment in
                        accordance with Section 3.3)

                       TOTAL                 US $1,550,907

           3.2   The consideration shall be satisfied by the payment of US
$1,550,907 in cash at the Closing less a retention of $25,000 against such
adjustment as is referred to in Clause 3.4.

           3.3   The purchase consideration for the Inventory shall be increased
or decreased by the difference by which the adjusted value of the Inventory on
the Transfer Date is greater than or less than US $634,922.  The adjusted value
of the Inventory on the Transfer Date will be determined as follows:

                 (a)   Within seven (7) days of the Transfer Date the Buyer and
the Seller will cause a physical count to be taken of the Inventory.  The
physical count will be adjusted to reflect purchases and sales of the Inventory
since the Transfer Date.  Representatives of the Buyer and the Seller shall be
entitled to be present at all times during the taking of the count.

                 (b)   Each item of the Inventory will be priced in accordance
with the statement of policies set out in the Second Schedule of this Agreement.

           3.4   The Seller and the Buyer will endeavor to agree on the adjusted
value of the Inventory on the basis set out in Clause 3.3 as soon as possible
after completion of the physical count.  In the event that they are unable to
agree on such value within 7 days the matter will be referred by the Seller or
the Buyer to a mutually agreeable independent firm of Certified Public
Accountants who will be asked to certify such adjusted value on the basis set
out in Clause 3.3 and whose certificate shall in the absence of manifest error
bind the parties.  The independent firm of Certified Public Accountants shall be
appointed by the Buyer and the Seller jointly or (in default of agreement as to
such appointment within 7 days of one of them notifying the other of its wish to
appoint an independent firm) by the American Arbitration Association on the
application of either of them.  The charges of the independent firm shall be
apportioned between the Seller and the Buyer as such firm shall decide.
Forthwith upon agreement between the Seller and the Buyer as to the adjusted
value or upon the receipt of a

                                      - 9 -

<PAGE>
copy of the certificate of the independent firm of Certified Public Accountants
as the case may be:

                 (a)   the Seller will, if the adjusted value is less than US
$609,922, pay to the Buyer the difference between the adjusted value and US
$609,922 and the Buyer shall be absolutely entitled to the retention of US
$25,000 referred to in Clause 3.2; or

                 (b)   the Buyer will, if the adjusted value is greater than US
$609,922, pay to the Seller the difference between the adjusted value and US
$609,922.

                                   WARRANTIES



           9.1   The Warrantors jointly and severally represent, warrant and
undertake to the Buyer, contracting for itself and as trustee for any successor
in title to part or all of the Business and Assets and the Property, that the
Warranties are true and correct in all material respects.

           9.2   The Warranties shall be qualified by reference to those matters
disclosed, but only to the extent fully, fairly and accurately disclosed, in the
Disclosure Letter.


           9.3   It is hereby agreed that:

                 (a)   The liability of the Warrantors in respect of any breach
or breaches of the Warranties relating to the Seller's title to the Inventory
and the Plant and Machinery and any other tangible assets shall be unlimited.

                 (b)   The aggregate liability of the Warrantors in respect of
any breach or breaches of the Warranties (other than those Warranties referred
to in Clause 9.3(a)) and other than in the case of any breach or breaches of the
Warranties where the Warrantors actually knew or were actually aware at the date
of this Agreement that the relevant Warranty was not true or correct in all
respects shall not exceed US $1,000,000.

                 (c)   The aggregate liability of the Warrantors in respect of
any breach or breaches of the Warranties other than those Warranties referred to
in Clause 9.3(a) in the case of any such breach or breaches where the Warrantors
actually knew or were actually aware at the date of this Agreement that the
relevant Warranty was not true or correct in all respects shall not exceed the
difference between US $2,000,000 and the amount of all other liability for any
breach or breaches of the Warranties pursuant to Clause 9.3(b).  For the
avoidance of doubt, the aggregate liability of the Warrantors in respect of all
claims for breach or breaches of the Warranties other than those Warranties
referred to in Clause 9.3(a) shall not exceed US $2,000,000.

                 (d)   The Warrantors shall not be liable in respect of any
claims under the Warranties unless details of the claim shall have been notified
to York in writing in reasonable detail on or before December 31, 1996 and
unless proceedings have been commenced within 6 months of such notification.

           9.4   The remedies of Buyer in respect of breach of any of the
Warranties shall continue to subsist notwithstanding Closing.

           9.5   The rights and remedies of the Buyer in respect of any breach
of the Warranties shall not be affected by any investigation made by or on
behalf of the Buyer into the affairs of the Seller, by the Buyer failing to
exercise or delaying the exercise of any of their respective rights or remedies
or by any other event or matter whatsoever except a specific and duly authorized
written waiver or release.

           9.6   All sums payable by the Warrantors under this Clause 9 shall be
paid free and clear of all deductions or withholdings whatsoever save only as
may be required by law.  If any such deductions or withholdings are required by
law, the Warrantors shall be obliged to pay such sum as will after such
deduction or withholding has been made leave the same amount as the recipient
would have been entitled to receive in the absence of any such requirement to
make a deduction or withholding.  If any sum payable by the Warrantors under
this Clause 9 shall otherwise be subject to tax in the hands of the recipient
the same obligation to make an increased payment shall apply in relation to such
tax liability as if it were a deduction or withholding required by law.  If
Warrantors shall fail to pay any sums payable under this Clause 9, Buyer shall
be entitled to set off the amount paid against any sum due from it to Seller, if
any, or if Buyer elects, Buyer may set off any amounts owed by Cornibi

becoming aware of the impending or threatened occurrence of any event which
would or might reasonably be expected to cause or constitute a breach (or would
have caused or constituted a breach had such event occurred or been known to the
Seller prior to the date of this Agreement) of any of the Warranties it shall
give written notice of the same to the Buyer and shall use its best efforts to
promptly prevent or remedy the same.

expense in circumstances where the act or omission or thing giving rise to the
entitlement to be indemnified also gives rise to a breach or breaches of the
Warranties the Buyer and/or IFR shall not be entitled to claim under both the
indemnity and the Warranties and in the event that the Buyer and/or IFR shall
claim under an indemnity the limitations of liability in Clauses 9.3(b) and
9.3(c) shall be reduced by the amount paid in settlement of the claim.  In

                                     - 16 -
<PAGE>

would constitute a breach of the same.  In the event that consent or novation is
required to such assignment:

                 (a)   The Seller shall at the Buyer's request use reasonable
endeavors with the cooperation of the Buyer to procure such novation or
assignment as aforesaid.

                 (b)   Unless and until any such Assumed Contract shall be

novated or assigned, the Seller will (so far as it lawfully may) give all such
assistance to the Buyer as the Buyer may reasonably require to enable the Buyer
to enforce its rights under such Assumed Contract and (without limitation) will
provide access to all relevant books, documents and other information in

any of the Assumed Contracts including enforcement at the cost of and for the
account of the Buyer of any and all rights of the Seller against the other party
to the Assumed Contract arising out of any cancellation by such other party or
otherwise.  If and to the extent that in respect of such Assumed Contracts any
such arrangements cannot be made, neither the Seller nor the Buyer shall
(without prejudice to Clause 7) have any further obligation to the other.

of the Assumed Contracts on or after the Transfer Date, the Seller shall receive
the same as trustee, shall record such payment separately in its books and shall

canvass or entice away from the Business or the Buyer (or endeavor to solicit,
canvass or entice away) the business of any person, firm or company who was at

a client or customer of or supplier to the Business for the purpose of offering
to such client or customer or obtaining from such supplier goods or services
similar to or materially competing with those of the Business or the products
produced by the Business;

                                 YORK GUARANTEE

     16.   York (referred to in this Clause 16 as "the Guarantor") as primary
obligor unconditionally and irrevocably:

           (a)   guarantees by way of continuing guarantee to the Buyer and IFR
(together referred to in this Clause 16 as "the Obligee"):

                                     - 20 -
<PAGE>

                 (i)   to discharge on written demand the due punctual and
complete payment of all sums payable to the Obligees by; and

                 (ii)  the performance and observance of all obligations for the
benefit of the Obligees of,

                 the Seller under this Agreement (such payment obligations,
liabilities and obligations being hereinafter called "the Obligations");

           (b)   undertakes to discharge on written demand such of the
obligations as are not Obligations to pay money as if it were the primary
obligor in respect thereof and agrees that any item or amount claimed by the
Obligees to be included in the Obligations being an obligation to pay money
which is not recoverable from the Guarantor under this Agreement on the basis of
a guarantee shall nevertheless be recoverable from the Guarantor as principal
debtor by way of indemnity and the Guarantor agrees to discharge that liability
on demand; and

           (c)   as a separate and independent obligation, agrees to indemnify
the Obligees against all direct losses and damages sustained by them or either
of them arising from any non-payment or default of any kind by the Buyer under
or pursuant to this Agreement.


     16.2  The Obligees shall not make demand or take any steps against the
Seller or any other person before giving two (2) full days' written notice to
the Guarantor of its intention to make written demand upon the Guarantor in
respect of the Obligations or any of them.  A "day" for the purpose of this sub-
clause shall not include a Saturday or a Sunday or other day when clearing banks
are not generally open in London for normal banking business.

     16.3  On making written demand in accordance with sub-clause 16.2 above
neither of the Obligees need make demand or take any steps against the Seller or
any other person before being entitled to exercise all and any of its or their
rights under this guarantee and indemnity.

     16.4  This guarantee and indemnity is a continuing guarantee and indemnity
and shall remain in full force and effect until all of the Obligations have been
discharged and performed in full.

     16.5   Each  payment to be made by the Guarantor  hereunder shall  be made
free and clear of all deductions or  withholdings of any kind, except  for those
required by law, and if any deductions or withholding must be made by law, the
Guarantor will pay that additional amount which is necessary to ensure that the
Obligees receive a net amount equal to the full amount which they would have
received if the payment had been made without the deduction or withholding.  If
any sum payable by the Guarantor shall otherwise be taxable in

                                     - 21 -
<PAGE>

the hands of the recipient in circumstances where it would not have been taxable
had it been paid by the Seller the same obligation to make an increased payment
shall apply in relation to such tax liability or if it were a deduction or
withholding required by law.

     16.6  The Guarantor shall pay interest on any amount due from it hereunder
from the date of demand until the date of payment in full (as well after as
before any judgment) calculated on a daily basis at the rate of three per cent
per annum (3%) for the first thirty (30) days and thereafter four per cent (4%)
per annum above in the case of any amount due in pounds sterling, the base rate
for the time being of the Barclays Bank PLC and, in the case of any amount due
in US dollars, LIBOR.  For these purposes LIBOR shall mean the rate per annum at
which US dollar deposits for the relevant period and amount are offered by
lending banks in the London Interbank Market.

     16.7  The Obligations of the Guarantor hereunder shall not be affected by
any act, omission, matter or thing whatever which but for this provision may
affect such Obligations or operate to release or otherwise exonerate the
Guarantor therefrom and accordingly (without prejudice to the generality of the
foregoing) either of the Obligees may without the Guarantor's consent and
without releasing or reducing the Guarantor's liability to it under this
Agreement;


           (a)   allow the Seller or any other person any time or indulgence;


           (b)   enter into, renew, vary, end or neglect to perfect or refrain
from enforcing any agreement or arrangement with or liability of the Seller or
any other person; or


           (c)   renew, vary, neglect to perfect, refrain from enforcing or
release any present or future security or guarantee or indemnity which either of
the Obligees holds from the Seller or any other person.


     16.8  Either of the Obligees may appropriate any sum paid by the Seller the
Guarantor or any other person or recovered or received on account of the
Obligations as it sees fit.


     16.9  (a)   Until all amounts which may be or become payable hereunder have
been irrevocably paid in full, the Guarantor shall not:

                 (i)   as a result of this guarantee and indemnity or any
payment or performance hereunder be subrogated to any right or security of
either of the Obligees; or

                                     - 22 -
<PAGE>

                 (ii)  claim or prove in competition with either of the Obligees
against the Seller or any other person whether by right of contribution, set
off, indemnity or otherwise;

           (b)   The Guarantor will not hold any security from the Seller in
respect of this guarantee and indemnity and any such security which is held in
breach of this provision will be held by the Guarantor on trust for the
Obligees.

     16.10 The Guarantor will reimburse the Obligees for all legal and other
costs, including reasonable attorney fees incurred by the Obligees in connection
with the valid enforcement of this guarantee and indemnity.


     16.11 The Guarantor agrees that if at any time and for any reason, and
whether with the consent of the Obligees or otherwise, any or all of the
Obligations (the "Assigned Obligations") are assigned, transferred or novated
to, or assumed by any other person (a "transferee"), then the Guarantor's
obligations pursuant to this guarantee and indemnity shall extend, mutatis
mutandis, to the transferee to the extent of the Assigned Obligations, and shall
not be impaired, released, diminished or discharged as the result of any such
assignment, transfer, novation or assumption.


                                  IFR GUARANTEE


     17.   IFR hereby guarantees to York and Seller the performance by Buyer of
its obligations set forth in Clause 7 hereof upon the same terms as York

       any such Products subsequently sold to such distributors, agents or other
       sales representative at a discount to reflect the fact that they have
       been used for demonstration or test purposes shall not be deemed sold at
       the Substituted Price.

       calculation of the purchase consideration adjustment. If the Gross Sales

       Regulations.

            Regulations); or

     (b)    anything done or omitted before the Transfer Date by or in relation
            to the Seller in respect of any contract of employment or any such
            collective agreements or any person employed in the Business which
            is deemed to have been done or omitted by or in relation to the
            Buyer in accordance with the 1981 Regulations; or

13.1   Subject to Clause 13.5.1 the Seller with effect from the Transfer Date
       hereby assigns to the Buyer all the Assumed Contracts which are either
       capable of assignment without the consent of other parties or not capable
       of assignment without the consent of other parties but such consent has
       been obtained prior to the date of Completion.

13.2   Subject to Clause 13.5.1 insofar as any of the Assumed Contracts are not
       assignable to the Buyer without the agreement of or novation by or
       consent to the assignment from another party and such consent has not
       been obtained as at the date of Completion this Agreement shall not
       constitute an assignment or attempted assignment if such assignment or
       attempted assignment would constitute a breach of the same. In the event
       that consent or novation is required to such assignment:

<PAGE>
                                     - 34 -

13.2.1  the Seller shall at the Buyer's request use reasonable endeavours with
     the co-operation of the Buyer to procure such novation or assignment as
     aforesaid;

13.2.2  unless and until any such Assumed Contract shall be novated or assigned
     as aforesaid the Seller shall hold the same in trust for the Buyer and its
     successors in title to the Business absolutely and the Buyer shall (if such
     sub-contracting is permissible and lawful under the Assumed Contract in
     question) as the Seller's sub-contractor perform all the obligations of the
     Seller under such Assumed Contract;

13.2.3  unless and until any such Assumed Contract shall be novated or assigned
     the Seller will (so far as it lawfully may) give all such assistance to the
     Buyer as the Buyer may reasonably require to enable the Buyer to enforce
     its rights under such Assumed Contract and (without limitation) will
     provide access to all relevant books documents and other information in
     relation to such Assumed Contract as the Buyer may require from time to
     time.

13.3.1  Subject to Clause 13.5.1 if such consent or novation is not obtained the
     Seller will co-operate with the Buyer and at the Seller's cost in any
     reasonable arrangements designed to provide for the Buyer the benefits
     under any of the Assumed Contracts including enforcement at the cost of and
     for the account of the Buyer of any and all rights of the Seller against
     the other party to the Assumed Contract arising out of any cancellation by
     such other party or otherwise. If and to the extent that in respect of such
     Assumed Contracts any such arrangements cannot be made neither the Seller
     nor the Buyer shall (without prejudice to Clause 9) have any further
     obligation to the other.

13.3.2  It is acknowledged by the parties that Kokusai Denshin, Denwa Company
     Limited ("KDD") and Corning Inc ("Corning") have indicated

<PAGE>
                                     - 35 -

     that they are prepared to enter into new contracts with the Buyer but will
     not agree to the assignment or novation of existing contracts with the
     Seller.

     The Buyer and the Seller agree that they will cooperate one with the other
     to ensure that the Buyer is able to enter into contracts with KDD and
     Corning substantially in the terms of the existing contracts to which the
     Seller is a party and the Seller is released from such contracts (so far as
     they remain to be performed). With respect to the contract between Corning
     and the Seller (a copy of which is contained in the Disclosure Letter) (the
     "Corning Contract") the further sum of US $90,000 exclusive of VAT is due
     to the Seller in respect of the first P106 machine supplied subject to
     Corning's acceptance of the machine in accordance with the Corning
     Contract.


     The Buyer agrees to carry out such work and provide such services as are
     required to enable the Buyer to perform its outstanding obligations to
     Corning in respect of the first P106 Machine and to be paid the outstanding
     sum of US $90,000 and the Seller agrees to reimburse to the Buyer forthwith
     on demand its direct costs (as defined in Clause 10.3) in doing so (whether
     or not the US$90,000 or any part thereof is paid by Corning to the Buyer or
     the Seller).

     In the event that a new agreement is entered into between Corning the Buyer
     and the Seller prior to acceptance by Corning of the first P106 Machine and
     payment of the US $90,000 to the Seller the Buyer will upon acceptance by
     Corning of the first P106 machine pay to the Seller the sum of US $90,000
     less its direct costs (as defined in Clause 10.3) in performing all
     outstanding obligations with respect to such machine in order to become
     entitled to the said US $90,000.The Seller agrees with the Buyer to
     indemnify the Buyer against all claims, actions proceedings demands and
     liabilities which it may incur under its new contract with Corning or
     otherwise in respect of the first P106 machine.

<PAGE>
                                     - 36 -

     For the avoidance of doubt, the Buyer shall have no liability or
     obligations to KDD or Corning under the existing contracts between those
     companies and the Seller save for its obligation to the Seller to perform
     the Seller's outstanding obligations to Corning in respect of the first
     P106 machine.

13.4 To the extent that any payment is made to the Seller in respect of the
     Assumed Contracts on or after the Transfer Date the Seller shall receive
     the same as trustee, shall record such payment separately in its books and
     shall account to the Buyer for the same on the Transfer Date or if received
     thereafter within 14 days of receipt.

13.5.1  Within 28 days of the Transfer Date the Buyer shall be entitled by
     written notice to the Seller to nominate any of the Agency Agreements as an
     Assumed Contract and in that event the provision of Clauses 13.1, 13.2,
     13.3 and 13.4 above shall apply to such contract with effect from the date
     of such nomination. For these purposes the arrangements with respect to the
     China office and Russian joint venture shall be deemed an Agency Agreement.

13.5.2  Any Agency Agreement not included as an Assumed Contract on the Transfer
     Date or nominated pursuant to Clause 13.5.1 above shall be retained by the
     Seller. With respect to each Excluded Agency Agreement the Seller will
     forthwith after the expiration of the 28 day period referred to in 13.5.1
     above advise the other party(s) thereto of the sale of the Business and
     terminate such agreement by serving the appropriate notice in accordance
     with the contractual terms of the agreement. The Seller shall indemnify the
     Buyer against all claims made actions, proceedings, demands, liabilities,
     costs and expenses incurred by the Buyer in respect of any claim made
     against it by the third party(s) to an Excluded Agency Agreement arising
     out of the termination thereof pursuant to the foregoing.

13.5.3  The Seller hereby acknowledges and consents to the Buyer approaching or
     soliciting any of the other parties to those Excluded

<PAGE>
                                     - 37 -

     Agency Agreements under which the Seller has appointed such third parties
     agents or distributors with a view to such third parties also being
     appointed to act as agents or distributors of the Buyer.

13.5.4  The Buyer shall have no obligation in any event under any provision of
     this Agreement to transact any business of any nature in Iran, Iraq or
     North Korea or assume any liaibility to any entity in any of those
     jurisdictions in relation to the Business.

     Buyer shall account for any such Debts received not later than 7 days after
     receipt.

14.3 If any debts due to the Buyer are paid to the Seller after the Transfer
     Date then the Seller shall not later than 7 days after receipt pay to the
     Buyer the amount received.

14.4 The Seller shall consult with the Buyer before commencing legal or
     arbitration proceedings or other action against any person for the recovery
     of any Debt if after the Transfer Date such person becomes or remains a
     customer of the Buyer in relation to the Business and, if the Buyer deems
     it necessary in order to preserve the goodwill of the Business, the Buyer
     may pay to the Seller the amount of such Debt and the Seller will assign
     the debt to the Buyer.

                                     - 39 -

17.2 The consideration referred to in Clause 3 is exclusive and without the
     addition of VAT, the Seller and the Buyer being of the view that this is a
     transaction for the transfer of the Business as a going concern to the
     Buyer as at and with effect from the Transfer Date and that accordingly the
     sale and purchase hereunder is not to be treated as either a supply of
     goods or a supply of services for the purposes of VAT by virtue of Article
     5 of the Value Added Tax (Special Provisions) Order 1995. However, if and
     to the extent to which all or any part or parts of this transaction shall
     subsequently be found to be such a supply, then the Buyer shall pay to the

     as the Seller may reasonably require.

<PAGE>

                                     - 41 -


            (i)  to discharge on written demand the due punctual and complete
                 payment of all sums payable to the Obligees by;
                 and

            (ii) the performance and observance of all obligations for the
                 benefit of the Obligees of,

            the Seller under this Agreement and under any Assignment of the
            Patents and the Goodwill, Copyright Unregistered Design Right and
            Know-How (such payment obligations, liabilities and obligations
            being hereinafter called "the Obligations")

     (b)    undertakes to discharge on written demand such of the obligations as
            are not Obligations to pay money as if it were the primary obligor
            in respect thereof and agrees that any item or amount claimed by the
            Obligees to be included in the Obligations being an obligation to
            pay money which is not recoverable from the Guarantor under this
            Agreement on the basis of a guarantee shall nevertheless be
            recoverable from the Guarantor as principal debtor by way of
            indemnity and the Guarantor agrees to discharge that liability on
            demand; and

     (c)    as a separate and independent obligation, agrees to indemnify the
            Obligees against all direct losses and damages sustained by them or
            either of them arising from any non-payment or default of any kind
            by the Seller under or pursuant to this Agreement.

18.2 The Obligees shall not make demand or take any steps against the Seller or
     any other person before giving two (2) clear days' written notice to the
     Guarantor of its intention to make written demand upon the Guarantor in
     respect of the Obligations or any of them. A "day" for the purpose of this
     sub-clause shall not include a Saturday or a Sunday or other day when
     clearing banks are not generally open in London for normal banking

18.3 On making written demand in accordance with sub-clause 18.2 above neither
     of the Obligees need make demand or take any steps against the Seller or
     any other person before being entitled to exercise all and any of its or
     their rights under this guarantee and indemnity.

18.4 This guarantee and indemnity is a continuing guarantee and indemnity and
     shall remain in full force and effect until all of the Obligations have
     been discharged and performed in full.

18.5 Each payment to be made by the Guarantor hereunder shall be made free and
     clear of all deductions or withholdings of any kind, except for those
     required by law, and if any deductions or withholding must be made by law,
     the Guarantor will pay that additional amount which is necessary to ensure
     that the Obligees receive a net amount equal to the full amount which they
     would have received if the payment had been made without the deduction or
     withholding. If any sum payable by the Guarantor shall otherwise be taxable
     in the hands of the recipient in circumstances where it would not have been
     taxable had it been paid by the Seller the same obligation to make an
     increased payment shall apply in relation to such tax liability as if it
     were a deduction or withholding required by law.

18.6 The Guarantor shall pay interest on any amount due from it hereunder from
     the date of demand until the date of payment in full (as well after as
     before any judgment) calculated on a daily basis at the rate of three per
     cent per annum (3%) for the first thirty (30) days and thereafter four per
     cent (4%) per annum above, in the case of any amount due in pounds
     sterling, the base rate for the time being of the Barclays Bank PLC and, in
     the case of any amount due in US dollars, LIBOR. For these purposes LIBOR
     shall mean the rate per annum at which US dollar deposits for the relevant
     period and amount are offered by lending banks in the London Interbank
     Market.

     omission matter or thing whatever which but for this provision may affect
     such Obligations or operate to release or

<PAGE>
                                     - 43 -

     otherwise exonerate the Guarantor therefrom and accordingly (without
     prejudice to the generality of the foregoing) either of the Obligees may
     without the Guarantor's consent and without releasing or reducing the
     Guarantor's liability to it under this Agreement:

     (a)    allow the Seller or any other person any time or indulgence;

     (b)    enter into, renew, vary, end or neglect to perfect or refrain from
            enforcing any agreement or arrangement with or liability of the
            Seller or any other person;

     (c)    renew, vary, neglect to perfect, refrain from enforcing or release
            any present or future security or guarantee or indemnity which

<PAGE>
                                     - 44 -

            respect of this guarantee and indemnity and any such security which

     (including value added tax) incurred by the Obligees in connection with the

     with the consent of the Obligees or otherwise, any or all of the
     Obligations (the "assigned obligations") are assigned, transferred or
     novated to, or assumed by (or are purportedly assigned, transferred or
     novated to, or assumed by) any other person (a "transferee"), then the
     Guarantor's obligations pursuant to this guarantee and indemnity shall
     extend, mutatis mutandis, to the transferee to the extent of the assigned
     obligations, and shall not be impaired, released, diminished or discharged
     as the result of any such assignment, transfer, novation or assumption.

19.  GUARANTEE (IFR)

     unconditionally and irrevocably:

     (a)    guarantees by way of continuing guarantee to the Seller and York
            (together referred to in this Clause 19 as "the Obligees");

       (i)  to discharge on written demand the due punctual and complete payment
            of all sums payable to the Obligees by;
            and

       (ii) the performance and observance of all obligations for the benefit of
            the Obligees of,

<PAGE>
                                     - 45 -

       the Buyer under Clauses 9, 10.3 and 13 this Agreement (such payment
       obligations, liabilities and obligations being hereinafter called "the
       Obligations")

     (b)    undertakes to discharge on written demand such of the obligations as
            are not Obligations to pay money as if it were the primary obligor
            in respect thereof and agrees that any item or amount claimed by the
            Obligees to be included in the Obligations being an obligation to
            pay money which is not recoverable from the Guarantor under this
            Agreement on the basis of a guarantee shall nevertheless be
            recoverable from the Guarantor as principal debtor by way of
            indemnity and the Guarantor agrees to discharge that liability on
            demand; and

     (c)    as a separate and independent obligation, agrees to indemnify the
            Obligees against all direct losses and damages sustained by them or
            either of them arising from any non-payment or default of any kind
            by the Buyer under or pursuant to this Agreement.

19.2 The Obligees shall not make demand or take any steps against the Buyer or
     any other person before giving two (2) clear days' written notice to the
     Guarantor of its intention to make written demand upon the Guarantor in
     respect of the Obligations or any of them. A "day" for the purpose of this
     sub-clause shall not include a Saturday or a Sunday or other day when
     clearing banks are not generally open in London for normal banking
     business.

19.3 On making written demand in accordance with sub-clause 19.2 above neither
     of the Obligees need make demand or take any steps against the Buyer or any
     other person before being entitled to exercise all and any of its or their
     rights under this guarantee and indemnity.

19.4 This guarantee and indemnity is a continuing guarantee and indemnity and
     shall remain in full force and effect until all of the Obligations have
     been discharged and performed in full.

19.5 Each payment to be made by the Guarantor hereunder shall be made free and
     clear of all deductions or withholdings of any kind, except for those
     required by law, and if any deductions or withholding must be made by law,
     the Guarantor will pay that additional amount which is necessary to ensure
     that the Obligees receive a net amount equal to the full amount which they
     would have received if the payment had been made without the deduction or
     withholding. If any sum payable by the Guarantor shall otherwise be taxable
     in the hands of the recipient in circumstances where it would not have been
     taxable had it been paid by the Buyer the same obligation to make an
     increased payment shall apply in relation to such tax liability as if it
     were a deduction or withholding required by law.

19.6 The Guarantor shall pay interest on any amount due from it hereunder from
     the date of demand until the date of payment in full (as well after as
     before any judgment) calculated on a daily basis at the rate of three per
     cent per annum (3%) for the first thirty (30) days and thereafter four per
     cent (4%) per annum above, in the case of any amount due in pounds
     sterling, the base rate for the time being of the Barclays Bank PLC and, in
     the case of any amount due in US dollars, LIBOR. For these purposes LIBOR
     shall mean the rate per annum at which US dollar deposits for the relevant
     period and amount are offered by lending banks in the London Interbank
     Market.

19.7 The Obligations of the Guarantor hereunder shall not be affected by any act
     omission matter or thing whatever which but for this provision may affect
     such Obligations or operate to release or otherwise exonerate the Guarantor
     therefrom and accordingly (without prejudice to the generality of the
     foregoing) either of the Obligees may without the Guarantor's consent and
     without releasing or reducing the Guarantor's liability to it under this
     Agreement:

     (a)    allow the Buyer or any other person any time or indulgence;


<PAGE>

     (b)    enter into, renew, vary, end or neglect to perfect or refrain from
            enforcing any agreement or arrangement with or liability of the
            Buyer or any other person;

     (c)    renew, vary, neglect to perfect, refrain from enforcing or release
            any present or future security or guarantee or indemnity which
            either of the Obligees holds from the Buyer or any other person; or

     (d)    compound with the Buyer or any other person.

19.8 Either of the Obligees may appropriate any sum paid by the Buyer, the
     Guarantor or any other person or recovered or received on account of the
     Obligations as it sees fit.

19.9 (a)    Until all amounts which may be or become payable hereunder have been
            irrevocably paid in full, the Guarantor shall not:

            (i)  as a result of this guarantee and indemnity or any payment or
                 performance hereunder be subrogated to any right or security of
                 either of the Obligees; or

            (ii) claim or prove in competition with either of the Obligees
                 against the Buyer or any other person whether by right of
                 contribution, set off, indemnity or otherwise;

       (b)  The Guarantor will not hold any security from the Buyer in respect
            of this guarantee and indemnity and any such security which is held
            in breach of this provision will be held by the Guarantor on trust
            for the Obligees.

19.10The Guarantor will reimburse the Obligees for all legal and other costs
     (including value added tax) incurred by the Obligees in connection with the
     valid enforcement of this guarantee and indemnity.

19.11The Guarantor agrees that if at any time and for any reason, and whether
     with the consent of the Obligees or otherwise, any or all of the
     Obligations (the "assigned obligations") are assigned, transferred or
     novated to, or assumed by (or are purportedly assigned, transferred or
     novated to, or assumed by) any other person (a "transferee"), then the
     Guarantor's obligations pursuant to this guarantee and indemnity shall
     extend, mutatis mutandis, to the transferee to the extent of the assigned
     obligations, and shall not be impaired, released, diminished or discharged
     as the result of any such assignment, transfer, novation or assumption.
