         Completion anything which is, or might constitute, or result in, a
         breach of any of the Warranties or provisions of Clause 8.1 as given on
         exchange and immediately prior to Completion.

                                       13

8.6      None of the information supplied by or on behalf of a Group Company,
         its agents or advisers or an Employee to one or more of the Vendors or
         to his or their agents or advisers in connection with the Warranties,
         Clause 8.1, the Disclosure Letter and/or the business and affairs of a
         Group Company constitutes a representation, warranty or undertaking as
         to its accuracy by a Group Company or an Employee to any of the
         Vendors, and each Vendor waives each and every claim against each Group
         Company and/or each Employee which he might otherwise have in respect
         of such information.

8.7      Each Vendor undertakes to notify the Purchaser before and after
         Completion immediately of any event, circumstance or thing which arises
         or comes to his knowledge which is or may be inconsistent with any of
         the Warranties or the provisions of Clause 8.1 or the Disclosure
         Letter, or which is or may constitute a breach of any of the Warranties
         or the provisions of Clause 8.1, or which may give rise to a claim
         under the Tax Covenant, or which may be material to be known by a
         purchaser for value of the Shares.

8.8      Without prejudice to the Purchaser's rights or remedies to claim
         damages pursuant to this Agreement including, without prejudice to the
         foregoing generality, in the event of any alleged fraud, gross
         negligence or fraudulent misrepresentation, if the Purchaser proceeds
         to Completion and there is a breach of any of the Warranties or
         provisions of Clause 8.1 or if any of the Warranties or provisions of
         Clause 8.1 is untrue, incomplete or inaccurate or misleading, and:

         8.8.1    the value of any asset (including one warranted to exist but
                  not in fact existing) of a Group Company is less or becomes
                  less than the value would have been had the breach not
                  occurred or had the Warranty or provision been true, complete
                  or accurate or not misleading; or

         8.8.2    the Purchaser or a Group Company incurs or becomes subject to
                  a liability or an increase in any liability which it would not
                  have incurred or been subject to had the breach not occurred
                  or had the Warranty or provision been true, complete or
                  accurate or not misleading; or

         8.8.3    the profits of a Group Company are less, or its losses are
                  greater, than would have been the case had the breach not
                  occurred or had the Warranty or provision been true, complete
                  or accurate or not misleading,

         then the Purchaser shall be relieved of its obligations in terms of
         this Agreement to allot and issue the Consideration Share and shall be
         entitled to withhold registration of any unregistered Consideration
         Shares with the US Securities and Exchange Commission until such time
         as any claim for breach of any Warranty or indemnity in terms of this
         Agreement has been satisfied in full and the Vendors shall compensate
         the Purchase (for itself and as trustee for each Group Company and each
         other member of the Purchaser's group) in accordance with this
         Agreement on demand by an amount equal to (as the Purchaser elects):

                                       14
<PAGE>   17

         8.8.4    the reduction in value of the asset or the liability or
                  increased liability incurred by the Group Company (as the case
                  may be); or

         8.8.5    the reduction in the value of the Shares thereby caused; or

         8.8.6    the amount by which the Group Company's profits are less or
                  its losses are greater (as the case may be).

8.9      Each Vendor shall be entitled to satisfy its obligations in respect of
         a breach of warranty to the Purchaser in whole or in part by
         transferring to the Purchaser or VRA (as the Purchaser may direct) the
         allotted but unsold Consideration Shares received by it.

8.10     The Purchaser represents, warrants and undertakes that save as
         disclosed in the Purchaser's Disclosure Letter the Purchaser's
         Warranties are at the date of this Agreement and at the Completion Date
         true, complete and accurate in all material respects.

9        COMPENSATION AND LIMITATION OF VENDORS' LIABILITY

9.1      This Clause 9 shall operate to limit the liability of the Vendors in
         respect of any claim by the Purchaser for any misrepresentation or
         breach of the Vendors' representations and warranties, but excluding
         those warranties in respect of Tax contained in paragraph 20 of
         Schedule 5, and notwithstanding any other provision of this Agreement,
         shall not operate to limit or exclude any breach as a result of fraud,
         gross negligence or fraudulent misrepresentation on the part of all or
         any of the Vendors. The Purchaser's sole remedy in the event of any
         misrepresentation or breach of warranty shall be as provided in this
         Agreement. The representations and warranties are given to the
         Purchaser and VRA only.

9.2      For the avoidance of doubt, notwithstanding any other provision in this
         Agreement to the contrary (other than (a) any liability for alleged
         fraud, gross negligence or fraudulent misrepresentation or (b) any
         liability pursuant to the Tax Warranties and the Tax Covenant), no
         individual Vendor shall be obligated to compensate the Purchaser for
         losses resulting from any misrepresentation or breach of any warranty
         made by the Vendors under this Agreement in an amount greater than the
         cumulative total of the value of that Vendor's holding of Consideration
         Shares (valued in terms of Clause 9.2.2) plus the net proceeds of sale
         (subject to any subsequent tax credit available) received by the Vendor
         in respect of any Consideration Shares issued to that Vendor under this
         Agreement and which have been sold or transferred and the relevant
         date. With respect to each individual Vendor (other than Skanditek
         Industriforvaltning AB and Syngenta Seeds AB), compensation shall be
         calculated after deduction of any tax liability incurred by that Vendor
         as a direct result of that Vendor satisfying his obligations in respect
         of a breach of warranty to the Purchaser pursuant to Clause 8.9,
         provided that:-

                                       15
<PAGE>   18

9.2.2    the total value of that Vendor's holding of Consideration Shares shall
         be calculated on the basis of a Market Value being the average Market
         Value in the 4 weeks immediately preceding the date of the Purchaser's
         claim;

9.2.3    that Vendor has exercised his best efforts to minimise his tax
         liability (including, without prejudice to the foregoing generality, by
         utilising any losses or reliefs available to that Vendor); and

9.2.4    that Vendor has exhibited to the Purchaser's satisfaction evidence of
         that Vendor's tax liability as aforesaid.

9.3      For the avoidance of any doubts, it is explicitly agreed that with the
         exception of any liability of the Vendors under the Tax Warranties and
         the Tax Covenant each party shall bear any liability for any tax that
         may directly or indirectly be levied on it in connection with the
         transaction contemplated by this Agreement.

9.4      The Purchaser shall not be entitled to bring any claim against the
         Vendors for any misrepresentation or breach of any warranties under
         this Agreement (with the exception of any claim under the Tax Covenant)
         unless a notice in writing of any such claim has been given by the
         Purchaser to each Vendor as soon as reasonably practicable but in no
         event later than 45 days after the date when the Purchaser becomes
         aware of any circumstance giving rise to a claim. The written notice
         shall be accompanied by reasonable particulars thereof specifying the
         nature of the misrepresentation or breach giving rise to the claim and,
         so far as practicable, the amount claimed in respect thereof.

9.5      The Vendors undertake to notify the Purchaser in writing as soon as
         practicable in respect of any matter which may give rise to a breach of
         warranty hereunder.

9.6      The Purchaser's right to claim for misrepresentation or breach of
         warranties (with the exception of those related to Tax) shall be made
         prior to the expiry of the 24 month period immediately following the
         Completion Date and in relation to warranties in respect of Tax shall
         be made prior to the expiry of the (84) month period immediately
         following the Completion Date, on which dates the Vendors liability
         hereunder shall expire. For the avoidance of doubt, a claim which has
         been notified to the Vendors whether contingent or otherwise shall
         remain valid and enforceable notwithstanding expiry of the foregoing
         time periods

         The Purchaser shall not be entitled to make claims for
         misrepresentation or breach of warranties if the Purchaser or its
         advisers prior to or on the date of this Agreement had knowledge of the
         misrepresentations or breach.

9.7      Upon the Purchaser becoming aware of any third party claim, action or
         demand or matter likely to give rise to any of these in respect of the
         warranties under this Agreement for which the

                                       16
<PAGE>   19

         Vendors may be liable, the Purchaser shall, or shall procure that the
         relevant Group Companies shall:

         9.7.1    as soon as reasonably practicable give written notice thereof
                  to each of the Vendors;

         9.7.2    meet with the Vendors and attempt to agree a course of action,
                  it being agreed by all parties that this shall however be
                  determined at the sole discretion of the Purchaser and in the
                  event of any disagreement the decision of the Purchaser shall
                  prevail.

9.8      The Purchaser shall not be entitled to recover more than once in
         respect of any individual breach of the warranties under this
         Agreement.

9.9      The Vendors shall be reimbursed by the Purchaser in respect of any sums
         paid to the Purchaser in respect of any successful claim against them
         for a misrepresentation or breach of warranty under this Agreement, but
         only to the extent and for the amount that the individual claim has
         been or is made good or is otherwise compensated whether by insurance
         or otherwise.

9.10     In addition to what is otherwise expressed in this Agreement, no claim
         for any misrepresentation or breach of any warranty under this
         Agreement shall be brought by the Purchaser against the Vendors:

(i)      if and to the extent that any such claim occurs as a result of any
         legislation not in force at the date hereof, or which takes effect
         retrospectively, or occurs as a result of any increase in the rate of
         tax in force at the date hereof or any change in the practice of the
         relevant tax authorities;

(ii)     if and to the extent that any such claim occurs as a result of any act,
         omission or transaction carried out at the request of or with the
         express written consent of the Purchaser before the Completion Date but
         excluding any act, omission or transaction undertaken to mitigate loss,
         remedy or prevent any matter which may or did give rise to any
         liability on the part of the Group or a misrepresentation or breach of
         warranty; and

(iii)    if and to the extent that any such claim would not have arisen but for
         an act, omission or transaction carried out by the Purchaser, or
         persons deriving title from the Purchaser or the Group Companies after
         the Completion Date but excluding any act, omission or transaction
         undertaken to mitigate loss, remedy or prevent any matter which may or
         did give rise to any liability on the part of the Group or any
         misrepresentation or breach of warranty.

9.11     No matter shall be the subject of a claim for any misrepresentation or
         breach of warranties under this Agreement to the extent that allowance,
         provision or reserve (whether of a specific or of a general nature) has
         specifically been made for such matter, in the Accounts or Management
         Accounts.

                                       17
<PAGE>   20

9.12     Irrespective of what is stated elsewhere in this Agreement, any actual
         or potential liability of the Vendors arising from this Agreement shall
         be apportioned according to received Consideration and shall thus not
         be joint and several.

10       RESTRICTIVE COVENANTS

         To protect the Purchaser's investment in the Company and the Company's
         Intellectual Property Rights and the goodwill attached to the business
         of the Company each Vendor shall execute and deliver to the Purchaser
         at Completion a Restrictive Covenant.

         all applicable laws and with Swedish general accepted accounting
         principals.

         applied in the audited statutory accounts submitted for the preceding
         three financial years.

4.3      The Accounts show a true and fair view of the state of affairs of each
         Group Company and of the Group as a whole as at, and of the profits and
         losses of each Group Company and of the Group as a whole for the
         financial period ended on, the Accounts Date.

4.4      No Group Company is, or has during the five year period ended on the

         liabilities (contingent or otherwise), risks or other expenditure of
         any nature (including, without limitation, any "off balance sheet"
         financing arrangements) which is not fully reflected in the Accounts or
         has not been fully reflected in the Group Company's accounts for any
         relevant period.

         CONTENT OF ACCOUNTS

4.5      The Accounts include:

                                       39
<PAGE>   42

         4.5.1    all fixed assets valued at cost less depreciation since the
                  date of acquisition and, where necessary, provision for
                  impairment;

         4.5.2    all stock (including raw materials and work in progress)
                  valued at the lower of cost and net realisable value and the
                  Accounts do not attribute any value to any obsolete, redundant
                  or excess stock or to any non-recoverable work in progress;

         4.5.3    all slow moving stock and damaged stock at an appropriate
                  written down value;

         4.5.4    all investments valued at cost less, where necessary,
                  provision for impairment;

         4.5.5    all debtors, prepayments and other current assets valued at
                  the lower of cost and net realisable value after making full
                  and proper provision for all bad debts and doubtful debts and
                  all other amounts considered to be irrecoverable;

         4.5.6    all liabilities and all capital and financial commitments of
                  each Group Company (whether actual, deferred, contingent,
                  quantified, disputed or otherwise and whether of an occasional
                  or seasonal nature) for which it is, or may become, liable up
                  to and including the Accounts Date, and the Accounts make full
                  and proper provision for, or in the case of contingent
                  liabilities and capital and financial commitments, full
                  disclosure of, all such liabilities and commitments;

         4.5.7    all Tax which has been or may be assessed on each Group
                  Company or for which it is, or may become, liable up to and
                  including the Accounts Date (whether actual, deferred,
                  contingent, quantified, disputed or otherwise) and the

         DEPRECIATION

         Accounts are the same as those used in the audited accounts of each
         Group Company and the Group for the preceding three financial years and
         are sufficient to ensure that each fixed asset of each Group Company
         will be written down to nil by the end of its useful life.

         TREND OF PROFITS

4.7      The results shown by the Accounts and by the profit and loss accounts
         of each Group Company and the consolidated audited profit and loss
         account of the Group for each of the preceding three financial years

         extraordinary, exceptional or non-recurring item, or by any transaction
         of an unusual nature or

         factor rendering the profit or loss for all or part of any period
         covered by those accounts unusually high or low.

         records have been fully, properly and accurately kept and completed by
         each Group Company and accurately record and reflect (in accordance
         with all applicable laws) all the assets and liabilities (actual and
         contingent) of each Group Company and all transactions to which it has
         been a party and each Group Company has operated adequate systems of
         internal financial control in relation to its book keeping.

         systems, controls and other information of each Group Company

         copies of all such policies of insurance of each Group Company are
         attached to, the Disclosure Letter (the "POLICIES").

8.2      All of the Policies are valid and enforceable and all premiums due have
         been duly and punctually paid and so far as the Vendors are aware
         nothing has been done, or omitted to be done, which makes or might make
         any of the insurance policies void or voidable.

8.3      the Group has no interest in, and is not a beneficiary under, and does
         not pay and is not liable to pay any part of the premiums on, any
         policy of life assurance.

         licence and where a Group Company is responsible for maintaining
         insurance the policy conforms in all respects with the requirements of
         the lease, tenancy or licence.

8.5      None of the Policies is subject to any unusual restrictions or bonuses
         or the payment of any premium in excess of the normal rate and no Group
         Company has done, or omitted to do, anything which will or may result
         in an increase in the premium payable for any Policy or whereby the
         renewal of any Policy will or may be affected.

8.6      No claim is outstanding, and during the 12 month period ending on the
         date of this Agreement no claims have been made, under any of the
         Policies and, as at the date of this Agreement, there are no

19       PENSIONS

19.1     Other than certain collective pension plans generally adopted by
         industry in Sweden and the Pension Scheme (the "Pension Schemes"),
         there is no arrangement to which the Company or any Group Company
         contributes or may become liable to contribute under which benefits of
         any kind are payable to or in respect of any employee, former employee,

20.1     The provisions for taxes and the provisions for social and parafiscal
         charges (including, but not limited to, social security contributions,
         and contributions to complementary welfare and pension schemes) which
         appear in the Accounts are sufficient for the payment of all taxes,
         social and parafiscal charges due or accrued at the Accounts Date
         (regardless of the date of the event which is the origin of the taxes,
         social or parafiscal charges and regardless of the date on which
         payment thereof is due). So far as the Vendors are aware, the Company
         and each Group Company have correctly filed all national, departmental
         and local tax and social declarations at the required time and have
         kept copies of the originals filed. All State, departmental and local
         taxes, and duties (including, but not limited to, corporation tax,
         value added tax, business tax, registration tax, land tax and customs
         duties) and all social and parafiscal charges owed by any Group Company

         limits;

         or parafiscal charges to be withheld by them in respect of wages,
         license fees, interest or any other sum payable by them;

         neither the Company nor any Group Company will be the subject of any
         additional assessment of taxes, fines or other punitive charges
         resulting from incorrect tax or social declarations filed before
         Completion;

20.4     as the VAT risk cannot be assessed, it is agreed between the Parties
         that any Claim for indemnification in this respect, on grounds arising
         out of non-payment of VAT and/or on the

                                       62
<PAGE>   65

         basis of a tax authority claim relating to VAT, shall be valid, shall
         entitle the Purchasers to indemnification and shall be borne by the
         Vendors severally.

21       PROPERTY

         TITLE

21.1     The Properties shown in Schedule 9 comprise all of the premises and
         land owned or occupied by, or used in connection with the businesses
         of, the Group Companies or in respect of which the Group Companies have
         an estate, interest, right or title.

21.2     The information set out in Schedule 9 of the Properties and their
         tenure is true and accurate in all respects.

21.3     Each Group Company named in section A of Schedule 9 as owner of the
         Properties is the legal owner of and beneficially entitled to the whole
         of the proceeds of sale of, and has a good and marketable title to, the
         Properties.

21.4     The real property Umea Formen 12 is registered at the Swedish Land
         Registry and the Company is registered with absolute title. The
         pre-registration deeds and documents relating to the real property do
         not contain any covenants, easements or matters not referred to on the
         registered title which are still enforceable. The pre-registration
         deeds and documents relating to the real property do not contain any
         title conditions, wayleaves or other rights in favour of third parties
         or matters not referred to on the registered title which are still
         enforceable.

21.5     Each Group Company has where so required in its possession and control
         or unconditionally held to its order all the properly constituted and
         stamped original documents of title and other documents and papers
         relating to the Properties.

21.6     There are no Encumbrances affecting the Properties or the proceeds of
         sale thereof and there is no outstanding monetary claim or liability,
         contingent or otherwise, in respect of the Properties.

21.7     None of the Properties is subject to any adverse or unduly onerous
         estate, right, interest, covenant, condition, restriction, obligation,
         stipulation, easement, option or other right or informal arrangement in
         favour of any third party and there is no agreement or commitment to
         give or create any of the foregoing and where any of the Properties is
         subject to any such arrangement or commitment no breach has occurred of
         any of the terms of such agreement or commitment. So far as the Vendors
         are aware, all conditions, restrictions and other obligations contained
         in the whole of the title deeds of or otherwise affecting or incumbent
         upon the Properties have been fully complied with.

21.8     The Properties drain into public sewers and are served by water,
         electricity and gas utilities and such utilities are either connected
         directly to the mains without passing through land in the

                                       63
<PAGE>   66

         occupation or ownership of a third party or, if such conducting media
         pass through land in the occupation or ownership of a third party, then
         the facilities, easements and rights necessary for the enjoyment and
         present use of the Properties are enjoyed on terms which do not entitle
         any person to terminate or curtail the same

21.9     There are no outstanding actions, disputes, claims or demands between a
         Group Company and any third party affecting the Properties or any
         neighbouring property.

21.10    Save for fixtures and fittings belonging to any tenant of the
         Properties all fixtures and fittings at the Properties are a Group
         Company's own absolute property and are free from Encumbrances.

21.11    The Properties are not subject to the payment of any outgoings other
         than the uniform business rate or water rates (and, if leasehold, rent,
         insurance and service charge reserved by the relevant lease) and all
         such payments have been made to date.

21.12    No development at, or use of, the Properties has been or is being
         undertaken in breach of the planning and building legislation or other
         such legislation in the country in which such Properties are situated
         or any regulations, bye-laws, orders, consents or permissions made or
         given thereunder and the actual use of the Properties as set out in
         Schedule 9 is the permitted use as of right or under the relevant
         planning legislation.

21.13    The planning consents, permissions and licences issued by any local
         authority or other body responsible for issuing such consents for
         development and use authorise all present or intended uses at the
         Properties and are either unconditional or are subject only to
         conditions which are neither unusual nor temporary and which have been
         satisfied or fully observed and performed, and such consents have not
         been issued on a temporary or personal basis and are not subject to an
         existing challenge as to validity. No application for planning
         permission is currently awaiting decision (whether on appeal or
         otherwise).

21.14    There is no resolution, proposal or order, whether formally adopted or
         not, for the compulsory acquisition by any local or other authority of
         the whole or any part of the Properties or any right of way or other
         burden serving the Properties nor are there any circumstances which are
         likely to lead to any such resolutions orders or proposals being made.

21.15    The Group Companies have discharged all development charges, monetary
         claims and liabilities under the relevant planning or other legislation
         and no such liability contingent or otherwise is outstanding.

21.16    There is no outstanding notice or order (statutory or otherwise)
         relating to the Properties or any business carried on at, or the use
         of, the Properties. There are no planning, development or road
         proposals within the vicinity of the Properties which might affect the
         Properties or the access to, or the business carried on at, the
         Properties. There are no circumstances likely to lead to any such
         notices, orders or proposals being issued or made.

21.17    None of the buildings, structures or erections on the Properties is a
         protected building of architectural, archaeological or historic
         interest, nor are any of the Properties a protected site or
         conservation area, situated adjacent to or near any protected site or
         area designated as an area of conservation or subject to a tree
         preservation order. The Properties are not situated in an area
         designated for clearance, redevelopment or improvement or any other
         similar purpose.

         STATE AND CONDITION OF PROPERTIES

         all other statutory requirements, regulations and bye-laws relating to
         the Properties have been fully complied with and there are no
         subsisting breaches of any provisions or conditions contained in or
         attaching to any certificates issued pursuant to such laws. The

21.19    The buildings and other structures on the Properties are in good and
         substantial repair and entirely fit for the purposes for which they are
         presently used.

21.20    None of the following has in the past affected or might in the future
         affect the Properties nor are the Properties situated in an area or
         subject to circumstances which may render any of them subject to:

         21.20.1  structural or other defects in the Properties or the building
                  of which the Properties are part or in any conducting media

                  part of either the relevant landlord or the Group Company and
                  there are no circumstances likely to give rise to the same. No

                  effect;

                  the ability of the tenant to renew the Lease upon the expiry
                  of the term;

         21.23.7  all steps in rent reviews have been duly taken and no rent

         21.23.10 no collateral assurances, undertakings or concessions have
                  been made by any party to the Lease; and

         21.23.11 the deeds and documents relating to the Leasehold Properties
                  and listed in section B of Schedule 9 comprise the entire
                  agreement between the relevant Group Company and the landlord

                           specified period or otherwise where such Tax

                           the Company) which was at any time before Completion
                           a member of the same group of companies as the
                           Company for any Tax purpose;

                  company and remaining unpaid where the company in question is

                  on the death of or by the estate of a deceased individual,

                  (a)      is at Completion a charge on any of the Shares or
                           assets or shares of the Company or gives rise to a
                           power to sell, mortgage or charge any of the Shares
                           or assets or shares of the Company; or

                  (b)      after Completion becomes a charge on or gives rise to
                           a power to sell, mortgage or charge any of the Shares
                           or assets or shares of the Company, being a liability
                           in respect of inheritance tax payable as a result of
                           the death of any person (whenever occurring) within
                           seven years after a transfer of value or a deemed
                           transfer of value where such transfer of value or
                           deemed transfer of value occurred on or before
                           Completion; or

                  (c)      arises as a result of a transfer of value occurring
                           on or before Completion (whether or not in
                           conjunction with the death of any person whenever
                           occurring) made by or to the Company;

         2.1.6    any Tax Liability of the Company in respect of any supply for
                  the purposes of VAT whenever made by any company which was a

                  time on or before Completion;

         2.1.7    any Taxation Liability affecting the Company in respect of or

                  arrangement (conditional or otherwise) incurred or entered
                  into on or before Completion; and

         2.1.8    any costs or expenses (including the costs and expenses of
                  taking or defending any action under this Schedule) incurred
                  or payable by the Company or the Purchaser in connection with
                  any Demand or any matter for which a claim is made under this
                  Schedule (such costs and expenses to include reasonable
                  compensation for time spent in connection with such matters by
                  employees and officers of the Purchaser and the Company).

2.2      For the avoidance of doubt any payment made by the Purchaser or the
         Company to discharge or remove any charge or power to sell, mortgage or
         charge shall give rise to a depletion in the assets of the Purchaser or
         the Company and notwithstanding any provision in this Schedule the
         Purchaser or the Company may disregard any right to pay tax in
         instalments in discharging or removing a charge or power.

2.3      Any payments made pursuant to paragraph 2.1 shall as far as possible be

         The covenant to pay given in paragraph 2 shall not cover any Tax
         Liability:

         respect of such Tax (other than for deferred Tax) is made in the
         Accounts; or

         requirements or published practice of any Taxation Authority made after
         Completion with retrospective effect; or

3.3      to the extent that it is attributable to any voluntary act or omission
         of the Purchaser or the Company outside the ordinary course of business
         after Completion which the Purchaser knew would give rise to a Tax
         Liability and which could have been avoided, unless such act:

         3.3.1    was carried out pursuant to a legally binding obligation
                  entered into on or before Completion; or

                                       85
<PAGE>   88

         3.3.2    is the disclosure of any information, matter or relevant to
                  any Taxation Authority; or

                  Vendors; or

         3.3.4    is the presentation for stamp duty purposes of any document;
                  or

3.4      To the extent that it arises in the ordinary course of business of the
         Company as carried on at Completion after the Accounts Date and before
         Completion and, for the purposes of this paragraph 3.4, the following
         shall not be regarded as resulting from the ordinary course of business
         of the Company:

         3.4.1    the acquisition, disposal or supply or deemed acquisition,
                  disposal or supply of any assets, goods, services or business
                  facilities of any kind (including the lending of money and
                  letting, hiring or licensing of any tangible or intangible
                  property) for a consideration deemed for Tax purposes to be
                  different to that actually received, to the extent of the
                  difference only;

         3.4.2    any Event which may result in the Company becoming liable to
                  pay or bear Tax chargeable directly or primarily against or
                  attributable directly or primarily to another person;

         3.4.3    the failure to deduct and/or account for Tax;

         3.4.6    a company ceasing to be a member of a group for any Tax
                  purposes; and

         3.4.7    incurring any penalty, interest, surcharge or fine in
                  connection with Tax.

                  indemnify the Trustees in respect of any liability arising to
                  any participant as a result of the Trustees complying with any
                  directions given by the Directors pursuant to the Trust Deed
                  and Rules.

                  at any time by giving to the Company and the remaining

                  such written notice within the following three months and the
                  retiring Trustee shall thereupon retire and shall not be
                  responsible for any costs occasioned by such retirement.

         (b)      Where a body corporate is acting as sole Trustee the Company
                  may by resolution of the Directors, with the prior written

                  corporate may be sole Trustee.

         (e)      If the Company shall not appoint a new Trustee or new Trustees
                  with effect from the date of expiry of the notice referred to
                  in sub-clause (a) of this Clause the Trustees may exercise
                  such power by executing

                  an instrument in writing signed by them as is necessary to

                  the provisions of the Scheme; and

        (iii)     subject as aforesaid any moneys at any time which are not
                  immediately required to be applied by the Trustees in a
                  particular manner may be placed on deposit (either with or
                  without interest) with any bank or other deposit taking
                  institution in Ireland as the Trustees may determine; and

        (iv)      upon the determination of the Scheme and to the extent that
                  the Residual Fund has been applied as aforesaid the Trustees
                  shall convert the Residual Fund to moneys and shall pay or
                  transfer any moneys then comprised in the Residual Fund to any
                  companies which at the date of such determination were
                  Participating Companies in proportion to the total moneys
                  provided by each of them to the Trustees. In the event of any
                  dispute as to the persons entitled to any part of the Residual
                  Fund the Trustees shall convert

                                       11
<PAGE>   13
                  such part into cash and pay the cash into Court and shall
                  thereupon be discharged from all obligations in relation
                  thereto. In no event may any Ordinary Shares which are part of

                  under this Trust Deed.

14.      (a)      ANY Trustee being an individual shall be entitled to receive
                  and retain as remuneration for his service hereunder such sum

         (b)      Any Trustee, being a solicitor, accountant, stockbroker, or
                  engaged in any other profession or business, shall be entitled
                  to be paid all reasonable professional or proper charges for
                  services rendered including acts which such Trustee, not being
                  engaged as aforesaid, could have done personally.

         (c)      Any Trustee, being a body corporate, (whether or not a trust
                  corporation) may charge and be paid such reasonable
                  remuneration or charges as shall from time to time be agreed
                  in writing between the Company and such body corporate and any
                  such body corporate (being a bank) shall be entitled (without
                  being liable to account for any profit or advantage so
                  obtained) to act as banker and perform any services in
                  relation to the Scheme on the same terms as would be made with
                  a customer in the ordinary course of its business as banker.

15       (a)      ANY Trustee, otherwise eligible to be a Participant, may
                  be so and may retain for his absolute benefit all the interest
                  to which he is entitled as a Participant in any Scheme Shares
                  acquired or received for him and any other money or money's
                  worth accruing to him as such and exercise all rights to which
                  he is entitled as a Participant.

         (b)      No decision of or exercise of a power by the Trustees shall be
                  invalidated or questioned on the ground that the Trustees or
                  any individual trustees of the Scheme or any member of the
                  Board of Directors of a corporate trustee of the Scheme had a
                  direct or personal interest as a beneficiary under the Scheme
                  in the result of any such decision or in the exercising of
                  such power.

         other office or employment in any Participating Company, may retain for
         his own absolute benefit any fees or remuneration received by him in
         connection with such office or employment notwithstanding that his
         appointment to or retention of such office or employment may be
         directly or indirectly due to the exercise or non-exercise of any votes
         in respect of shares or other securities in the Company held by the
         Trustees or other persons on their behalf under the trusts of the
         Scheme.

         purchasing, holding, dealing in and disposing of any stock, shares or
         other securities whatsoever of any Participating Company or any
         subsidiary or

         holding company thereof or any subsidiary of any such holding company
         or from otherwise at any time contracting or entering into any
         insurance, financial or other transaction with any such company or
         being interested in any such transaction or accepting and holding the
         trusteeship of any debenture stock or other securities of any such
         company neither shall such Trustee be liable to account for any profit
         made by him thereby or in connection therewith.

                           election of a chairman he shall be chosen by lots;

                  (ii)     all business brought before a meeting of the Trustees
                           shall be decided by a majority of the votes of the
                           Trustees present and voting thereon and, in the case
                           of equality of votes, the chairman of the meeting

                  person from time to time nominated by the Company and
                  authorised in writing for the purpose by all the Trustees.

         (c)      The Trustees may from time to time appoint for the proper
                  administration and management of the Scheme such secretarial
                  or executive officers or staff or other persons as they
                  consider desirable and the Directors shall approve on such
                  terms as they think fit.

         (d)      The Trustees may from time to time in writing delegate any

                  the exercise of the foregoing powers except to the extent that

20.      (a)      THE Company with the concurrence of the Trustees may at
                  any time and from time to time, in the case of this Deed, by
                  deed supplemental hereto and, in the case of the Rules, by
                  resolution of the Directors modify, alter, amend or extend the
                  Scheme in any respect (such modification, alteration,

                  "amendment") provided that

                  (i)      no amendment shall alter to the disadvantage of a
                           Participant his rights in respect of any Scheme
                           Shares appropriated before the date of such
                           amendment;

                  (ii)     no amendment shall be made which would or might
                           infringe any rule against perpetuities or which could
                           result in the Scheme ceasing to be an employees'
                           share scheme;

                  (iii)    no amendment shall take effect unless the prior
                           written approval of the Revenue Commissioners to the
                           Scheme as amended thereby shall have first been
                           obtained.

                  (iv)     no amendment shall be made which would entitle a
                           Participating Company to receive a distribution of
                           or have any rights in an Ordinary Share or Scheme

                  sub-Clause (a) of this Clause but notwithstanding the

                  obtaining the

                                       17

                  prior approval thereto of any other person, modify or alter or
                  amend the Scheme in any way which may be necessary in order to
                  secure the initial approval of the Scheme by the Revenue
                  Commissioners under Chapter I of Part I7 of the Act and
                  Schedule 11 to that Act.

21.      THE Scheme and the trusts hereby created shall be determined on the
         happening of either of the following:-

         (i)   the date on which the Directors resolve to terminate the Scheme
               which they shall be entitled to do only on a date on which there
               is no Scheme Share or Ordinary Share held pursuant to this
               Trust Deed; or

         (ii)  the expiry of twenty one years after the death of the last
               survivor of the issue living on the date of this Deed of the late

22.      Neither the Trustees nor any Participating Company shall be obliged to
         perform any obligation under this Deed or the Rules to the extent that
         such action would be contrary to any enactment or Exchange Control or
         other regulation for the time being in force in Ireland.

23.      The Trustees shall make all such returns as the Revenue Commissioners
         may from time to time require.

24.      All disputes and differences arising out of the Scheme or otherwise in
         connection therewith may be referred by the Trustees to arbitration
         pursuant

                                       18
<PAGE>   20

         to the provisions of the Arbitration Acts of 1954 and 1980 and any
         Participant so affected shall submit to such arbitration.

25.      THIS Deed shall be governed by and construed in accordance with the
         Laws of Ireland.

IN WITNESS whereof the Deed has been executed by each of the parties the day and

         (a)      As soon as practicable following the Cut-Off Dates in each
                  year in which the Directors intend to operate the Scheme the
                  Directors shall determine the amount (if any) of the
                  Entitlements.

                  On each announcement date the Company shall issue a notice in
                  the form set out the Second Schedule (or such other forms as
                  may be approved by the Company) to each Eligible Employee of
                  the amount of his Entitlement. The Company shall notify each

                  Entitlement paid to him in cash, then he must elect to do so
                  by notice in writing to the Company not later than 14 days
                  after the Announcement Date or within such longer period as
                  the Company may allow. If the Eligible Employee so elects then
                  the amount covered by such election shall be paid to the
                  Eligible Employee by the Company through its payroll system.
                  If no such election is made such amount shall be paid to the
                  Trustees to be applied by them in acquiring on his behalf
                  Ordinary Shares. Each Eligible Employee may increase his
                  Entitlement by an amount equal to a maximum of 7.5 % of his
                  basic gross salary, by giving appropriate instructions to the
                  Company no later than the date he submits a contract of
                  participation in respect of each relevant Appropriation Date.

         (b)      Each Participating Company shall as soon as practicable after
                  the expiry of the Invitation Period to which the Entitlements
                  relate pay to the Trustees the appropriate aggregate amounts
                  due following the completion and return of contracts in
                  accordance with Rule 2 by Eligible Employees employed by it
                  less any amount of the Residual Fund which the Directors may
                  have directed the Trustees to apply in

                                       29
<PAGE>   31

                  the acquisition of Ordinary Shares for appropriation to such
                  Eligible Employees and any Ordinary Shares forming part of the
                  Residual Fund which the Directors may have directed the
                  Trustees to appropriate to such Eligible Employees.

         (c)      As soon as reasonably practicable after the confirmed receipt
                  from the Participating Companies of the amounts referred to in
                  paragraph (b) of this Rule the Trustees will apply the
                  aggregate of such amounts together with any amount of the
                  Residual Fund directed by the Directors to be so applied in
                  accordance with paragraph (b) of this Rule in the acquisition
                  of Ordinary Shares for appropriation to each such Eligible
                  Employee in accordance with the provisions of this Rule on the
                  basis that the aggregate Initial Market Value of the Ordinary
                  Shares appropriated to him is as nearly as possible pro rata
                  to the amount of his Entitlement that has been paid to the
                  Trustees. Provided that in the case of any Eligible Employee
                  in any Year of Assessment neither the total of the
                  Entitlements nor the aggregate Initial Market Value of Scheme
                  Shares appropriated shall exceed the amount for the time being
                  specified as being the limit on individual appropriations for
                  the purposes of paragraph 3(4) of Schedule 11 to the Act.

         (d)      Where, due to circumstances outside their control the Trustees
                  are unable to acquire sufficient Ordinary Shares by the
                  purchase or subscription of Ordinary Shares as directed by the
                  Directors to satisfy in full appropriations pursuant to Rule
                  4(c) the Trustees shall reduce the appropriations pro-rata.
                  This shall not preclude the

                                       30
<PAGE>   32

                  Trustees from taking whatever time they and the Directors feel
                  is reasonable in the particular circumstances to acquire
                  ordinary shares subject to the provisions of Rule 4(f) and
                  Rule 4(g) below.

         (e)      If the basis on which the Ordinary Shares are appropriated
                  would otherwise give rise to the appropriation of a fraction
                  of an Ordinary Share the Trustees shall round such
                  appropriation up or down to the next whole Ordinary Share as
                  they in their absolute discretion think fit. In the event that
                  a portion of the Ordinary Shares acquired by the Trustees
                  carries the right to receive any dividends which have been
                  declared the Trustees shall appropriate those dividends among
                  Eligible Employees in the same proportions as provided in
                  paragraph (c) of this Rule.

         (f)      The Trustees shall appropriate the Ordinary Shares so
                  acquired on one day within thirty days of the expiry of the
                  Invitation Period.

         (g)      To the extent that the Trustees have not applied the whole of
                  the amount received by them in the acquisition of Ordinary
                  Shares in accordance with paragraph (c) of this Rule within
                  thirty days of the confirmed receipt from the Participating
                  Companies of the amounts referred to in paragraph (b) of this
                  Rule, they shall pay the balance thereof to the Participating
                  Companies who provided the same.

         (h)      The Trustees shall at the discretion of the Directors either
                  sell for the best consideration in money reasonably obtainable
                  at the time any Ordinary Shares which they do not appropriate
                  under this Rule and retain the net proceeds of sale or retain
                  such Ordinary Shares as part of the Residual Fund.

         (j)      If following the date on which the Trustees are entered on the
                  Parent Company's register of members but before the
                  Appropriation Date of any Ordinary Shares the Trustees shall
                  become entitled in respect of such shares to

                  (i)      any dividends or other distribution they shall
                           retain same as part of the Residual Fund; or

                  (ii)     any other rights to be allotted securities in the
                           Parent Company (other than an issue of capitalisation
                           shares of the same class as Ordinary Shares then held
                           by the Trustees pending an appropriation which
                           capitalisation shares shall be retained by the
                           Trustees and shall form part of the Ordinary Shares
                           to be appropriated) they shall use their best
                           endeavours to sell those rights for the best
                           consideration in money reasonably obtainable at the
                           time and the Trustees shall retain the proceeds as
                           part of the Residual Fund.

         (k)      No Ordinary Shares shall be appropriated to any Eligible
                  Employee after a date three years prior to the expiry of the
                  period specified in

                  the Directors by resolution decide.

         (l)      The Directors may determine at any Cut-Off Date that there
                  shall be no Entitlements and may so decide at any subsequent

         (c)      A Participant shall not be entitled to give any direction
                  under paragraph (a) of this Rule or to assign or charge or
                  otherwise dispose of his beneficial interest in any Scheme
                  Shares before the end of the Period of Retention applicable to

         (a)      In the event of the Parent Company proposing to make a rights

                  (i)      to instruct the Trustees to exercise the rights in
                           respect of all his Scheme Shares provided that such
                           instruction is accompanied by payment in cash of the
                           amount necessary to exercise such rights; or

                  (ii)     to instruct the Trustees to exercise the rights in
                           respect of some only of his Scheme Shares and to
                           dispose of the rights nil paid in respect of the
                           remainder and either

                           (A)  to pay to the Trustees any amount in excess of
                                the amount of the disposal proceeds necessary to
                                exercise such rights; or

                           (B)  to instruct the Trustees to pay to him any
                                amount of the disposal proceeds in excess of the
                                amount necessary to exercise such rights; or

                  (iii)    to instruct the Trustees to dispose of the rights nil
                           paid in respect of all his Scheme Shares and pay the
                           proceeds to the Participant.

                  The Participant shall instruct the Trustees accordingly within
                  any period of time specified by the Trustees and shall, if
                  appropriate, pay to the Trustees in cash any amounts necessary
                  in order to carry out such instructions. The Trustees shall
                  subject to receipt of the cash as aforesaid carry out the

                  be, the Company for exercise of the rights. If a Participant
                  shall fail to give any direction to and shall not otherwise
                  have authorised the Trustees, they shall sell all rights in
                  respect of the Participants Scheme Shares nil paid and pay the
                  proceeds to that Participant.

         (b)      In the event that the Trustees do not receive what they
                  consider sufficient notice of the offer to enable them to
                  operate the provisions of Rule 6(a) above from the Parent
                  Company or from any third party by whom the shares are held on
                  behalf of the Trustees, they may (subject of Part XII of the
                  Companies Act 1963 and the European Communities (Transferable
                  Securities and Stock Exchange) Regulations 1992) take such
                  action as they deem to be appropriate in the circumstances
                  including the disposal of the rights nil paid in respect of
                  the Scheme Shares and payment of the proceeds to the
                  Participants and no liability shall attach to the Trustees
                  consequent on taking such action, and in particular any
                  disposal of rights pursuant to this sub-clause shall be deemed
                  to be a disposal of rights pursuant to a direction given on
                  behalf of a Participant within the meaning of the Act.

         (c)      In the event of an offer being made or a transaction being
                  proposed in any of the circumstances described in Section
                  511(6) (a), (b) or (c) of the Act, the Trustees shall
                  forthwith notify each Participant and shall act in accordance
                  with the instructions of the Participant in dealing with his
                  Scheme Shares and in the absence of any such instructions
                  shall take no action.

                  (a) or (c) of this Rule or on a capitalisation issue shall be
                  deemed to have been appropriated to a Participant on the

                  they were allotted.

         (e)      In the event that any Participant shall on the Trustees

                  security, the Trustees shall use their best efforts to sell
                  such securities as represent the aggregate of the fractions so
                  arising and shall distribute the proceeds of sale (after
                  deducting any expenses of sale and any taxation which may be
                  payable by the Trustees in respect thereof) to the
                  Participants concerned provided that any such entitlement
                  which is less than IR(pound)1 shall be retained by the
                  Trustees and held as part of the Residual Fund.

                  the Participant concerned shall be payable in the case of

                  (ii)     a transfer following the death of a Participant; or

             BAY NETWORKS IRELAND LIMITED SHARE PARTICIPATION SCHEME

                                EMPLOYEES BOOKLET

The Bay Networks Ireland Limited Share Participation Scheme has been introduced
to enable employees to acquire shares in our parent company, Northern Telecom
Limited in a tax efficient way. Northern Telecom Limited is a public company,
quoted on the Toronto Stock Exchange.

You may use part of your Bay Pounds entitlement under the Bay Core Plus Plan
which are not allocated for other benefits to acquire shares. The amount of the
Bay Pounds which may be used for this purpose is based on the allocation to a
single person, i.e. the extra (pound)540 paid to family members is not available
for investment in shares.

You can also increase your share entitlement by foregoing salary. There is a
limit to the amount of salary that can be foregone and an overall limit of
(pound)10,000 (currently) on the value of the shares that can be allocated to
you in any tax year.

The shares will be held by the Trustees of the Scheme on your behalf. Shares
cannot normally be sold for two years from the date of allocation.

                                       44
<PAGE>   46

You are not taxed on the value of the shares when they are allocated to you and,
provided the shares are left with the Trustees for three years, no subsequent
charge to income tax will arise.

This booklet gives a summary of the main provisions of the Scheme which is
governed by rules designed to meet the requirements of the Revenue
Commissioners. In the event of any discrepancy or inconsistency between this
booklet and the rules the latter will prevail.

If you require further information or wish to see a copy of the Rules you should
ask Claire Hurley.

You should note that although the shares are potentially a very good investment
they could also go down in value as with any investment in company shares. You
should bear this in mind when deciding how much to invest in the Scheme.

1.   WHO IS ELIGIBLE TO PARTICIPATE IN THE SCHEME?
     You are eligible to participate if:-

     i.   you are employed in the Republic of Ireland by Bay Networks Ireland
          Limited and are liable to income tax on your earnings from that
          employment; and

     ii.  you have completed at least six months service with Bay Networks
          Ireland Limited at the "cut-off date", i.e. the 1st April each year

     iii. you are not serving notice of termination of your contract of
          employment

2.   WHEN CAN I PARTICIPATE?

     You normally have two opportunities each year to participate in the Scheme.

     I.  BAY POUNDS
         At the beginning of each Flex Plan year you can opt to invest part of
         your Bay Pounds to acquire shares. Details of the amounts available for
         this purpose will be provided to you at this time.

         At the end of the Plan year you will be asked to confirm your decision
         by completing an Application Form. A specimen form is attached.

     II. SALARY FOREGOING

         In any year in which you opt to invest any of your Bay Pounds to
         acquire shares you may also increase your share entitlement by
         foregoing salary.

         Salary foregoing involves opting for a reduced salary with the amount
         of reduction used to purchase shares. If you opt for salary foregoing
         your salary will be reduced on the first paydate after the 6th April
         each year. Should the amount foregone be greater than is available for
         investment in shares the excess will be paid to you through the
         payroll.

         The maximum amount which can be used to purchase shares under salary
         foregoing is the lesser of (i) the amount allocated from Bay Pounds and
         (ii) 7 1/2% of salary. In addition the total value of your share
         purchases in any one tax year cannot exceed the legal maximum
         (currently (pound)10,000).

         If you opt for salary foregoing you will be asked to complete an
         Acceptance Letter at the start of the initial tax year agreeing to the
         reduction in salary - a specimen form is attached. Any monies available
         under salary foregoing to purchase shares will be invested at the end
         of the tax year.

     III.INITIAL PARTICIPATION

         When you decide to participate in the Scheme initially you must sign a
         Form of Acceptance and a Contract of Participation addressed to the
         Company and the Trustees of the Scheme. A specimen form is attached.

3.   HOW MANY SHARES WILL BE ALLOCATED TO ME?

                                       46
<PAGE>   48

     The number of shares allocated to you will depend on the amount of Bay
     Pounds which you decide to use to purchase shares, any salary foregone for
     shares and the price of the shares at the date of allocation. The sum
     available will be used to purchase ordinary shares in Northern Telecom
     Limited which will be held on your behalf by the Trustees. Details of all
     purchases will be sent to you by the Trustees.

4.   HOW LONG MUST I LEAVE MY SHARES WITH THE TRUSTEES?

     Your shares must normally be held by the Trustees for a minimum period of
     two years from the date on which they are allocated to you. During this
     period you may not deal with your shares in any way, e.g. you may not sell
     them, give them away or pledge them as security unless within that period:-

     i.   You cease to be employed by the Company because of injury,
          disability or redundancy; or

     ii.  You reach State Pension Age (66 years).

     In either of these circumstances your shares may be sold or transferred to
     you. In the event of your death your shares may be sold or transferred to
     your legal personal representatives.

5.   WHEN CAN I SELL MY SHARES OR HAVE THEM TRANSFERRED INTO MY NAME?

     At any time after the end of the two years from the date the shares were
     allocated to you, you may instruct the Trustees to sell your shares for you
     or to transfer them into your name so that you may keep them or deal with
     them as you wish. However, as you will see from question 7 below, if you
     instruct the Trustees to do either of these things within three years from
     the date your shares were allocated to you, you will have to pay some
     income tax. Therefore, unless you instruct them to do otherwise, the
     Trustees will continue to hold your shares for you until three years from
     the date of allocation.

6.   WILL I ENJOY THE RIGHTS OF A SHAREHOLDER WHILE MY SHARES ARE HELD BY
     THE TRUSTEES?

     Yes, through the Trustees who hold the shares on your behalf and who will
     carry out your instructions. You will receive any dividends declared and be
     eligible to participate in any bonus or rights issues of new shares.
     However, until your shares are transferred into your own name, or are sold
     by the Trustees on your instructions, they will appear on the Northern
     Telecom Limited register of shareholders in the name of the Trustees. It is
     therefore, the Trustees, as the holders of the shares, who will have the
     legal right to attend and vote at general meetings.

7.   WHEN AM I TAXED ON MY SHARES?

     I.  ON ALLOCATION OF SHARES
         You are not taxed on the value of your shares when they are first
         allocated to you

     II. ON SALE OR TRANSFER

         After the initial period of two years mentioned in question 4 you can
         ask the Trustees either to sell your shares, or transfer them into your
         name.

         If the sale or transfer takes place before the Trustees have held the
         shares for three years the Trustees are obligated to deduct income tax
         at the standard rate on 100% of the lesser of the then value of the
         shares or the amount you paid for them originally.

         If you leave the shares with the Trustees for 3 years before asking for
         them to be sold or transferred you will have no liability for income
         tax on the value of the shares.

    III. CAPITAL GAINS TAX

         If your shares are sold by the Trustees or later by yourself for more
         than their original value you may be liable to capital gains tax on any
         increase over that value. However, under present tax law there is no
         capital gains tax on any gain, calculated after indexation relief, you
         make on the sale provided your capital gains from all sources in the
         year do not exceed the current personal exemption limit of
         (pound)1,000. (A separate limit of (pound)1,000 available to spouses
         cannot be offset against any such gains).

         The (pound)1,000 exemption applies to your capital gains from all
         sources. Tax law changes from time to time and you should confirm the
         position before the shares are sold.

8.   HOW DO I RECEIVE DIVIDENDS?

     Any dividends declared on the ordinary shares of Northern Telecom Limited
     will be paid to you with tax deducted at source. If you are liable to
     income tax at the higher rate you must declare the amount of dividends on
     your tax returns and you may be liable for additional tax depending on your
     marginal rate of tax.

9.   WHAT IF I LEAVE THE COMPANY?

     If you leave the Company other than because of retirement at State Pension
     Age, injury, disability or redundancy, your shares will continue to be held
     by the Trustees as if you were still employed by the Company and at any
     time after two years from the date the shares were first allocated to you,
     you can instruct the Trustees to sell the shares or transfer them into your
     name.

10.  WHAT HAPPENS IS I LEAVE BECAUSE OF INJURY, DISABILITY OR REDUNDANCY OR I
     REACH STATE PENSION AGE?

     If you leave the Company at any time because of injury, disability or
     redundancy, or if you reach age 66 (whether or not you also leave the
     Company), you may ask the Trustees to sell your shares or transfer them
     into your name. If the sale or

                                       48
<PAGE>   50

     transfer occurs within three years from the date shares were first
     allocated to you, then in these particular circumstances the proportion
     liable to income tax (see question 7) is only 50%. If the sale or transfer
     occurs later, then as previously indicated no income tax will be payable.

     In either case there may be some capital gains tax to pay on a sale - see
     question 7 (iii).

11.  WHAT HAPPENS IF I DIE?

     In the event of your death your shares may be transferred to your legal
     personal representatives or they may be sold and the proceeds paid to them.
     No income tax or capital gains tax will be payable at the time of transfer
     or sale (regardless of how long the shares have been held in trust).

12.  WHAT IF NORTHERN TELECOM LIMITED HAS A RIGHTS ISSUE?

     Your position in the event of a rights issue is fairly complex. Should
     Northern Telecom Limited make a rights issue full details of your rights
     and your consequential tax position will be notified to you.

13.  WHAT IF NORTHERN TELECOM LIMITED MAKES A BONUS ISSUE?

     Bonus shares issued in respect of shares held on your behalf by the
     Trustees will be treated for all purposes of the Scheme as if they had been
     allocated to you at the same time as the original shares to which they
     relate.

14.  WHAT IF THERE IS A TAKEOVER BID FOR THE NORTHERN TELECOM LIMITED?

     In the event of a takeover bid full details of the bid, your rights and
     your consequential tax position will be notified to you.

15.  WHO ARE THE TRUSTEES OF THE SCHEME?

     Mercer Trustees Limited are Trustees of the Scheme. They are responsible
     for the management and administration of the Scheme and for looking after
     your interests as a shareholder.

         time of the direction as notified to me by the Trustees.

With effect from ... I accept the following changes to my pay and benefit terms:

i)   My basic salary is reduced by ...% (between 1/2% and 7 1/2% of salary - do
     not use fractions other than 1/2%).

ii)  I will have an entitlement to shares under the Bay Networks Ireland Limited
     Share Participation Scheme each year equivalent to the amount by which my
     salary is foregone (in addition to any other entitlement as a result of any
     Bay Pounds used to purchase shares).

I also acknowledge that I have read notes 1-4 below.

NOTES:

1.   Your total share allocation in respect of any tax year cannot exceed the
     limit permitted by legislation - currently (pound)10,000. If you insert a
     percentage in (i) above, which with any Bay Pounds allocated to shares will
     produce a sum in excess of (pound)10,000, your share allocation will be
     limited to this amount and the percentage under (i) above will be adjusted
     accordingly in the next available payroll.

                                       53

2.   Salary foregoing cannot apply in any tax year in which you do not use any
     of your Bay Pounds to purchase shares.

3.   All your benefits and future reviews will be calculated by reference to
     salary before foregoing. However salary foregoing could have an impact on
     your retirement benefits if you are close to retirement; if you are paying
     maximum Additional Voluntary Contributions (AVCs) it may also be necessary
     to restrict the amount that can be paid. In either case you should seek
     advice on your position.

4.   Subject to 1 and 2 above the amount of any salary foregone will be applied
     to purchase shares at the same time that any Bay Pounds is also being
     applied (usually in March of each year).

BASIS OF CALCULATION OF ENTITLEMENTS

     1.  The entitlement of each Eligible Employee under the Scheme shall be

         gross salary plus (pound)140) and which may be applied by an employee
         to provide such benefits as are provided under that Plan including
         shares, and

     2.  Each Eligible Employee shall have the option to forego between 0.5% and
         7.5% of basic gross salary towards Ordinary Shares subject to this

Provided that, in the case of any Eligible Employee the total of the
Entitlements in any Year of Assessment shall not exceed the amount for the time
being specified as being the limit on individual appropriations for the purposes
