     the Initial Documentation List.

(2)  Each issue

     The obligations of a Dealer under any agreement for the issue and

          in the condition (financial or otherwise) of the relevant Issuer and

          of the issue and offering of the Notes from that set forth in the
          Offering Circular on the relevant Agreement Date, nor the occurrence
          of any event making untrue or incorrect to an extent which is

          either the relevant Issuer or (as the case may be) the Guarantor
          under this Agreement, the Notes, the Agency Agreement, the Deed of
          Covenant or the Deed of Guarantee which has not been waived by the
          relevant Dealer on or prior to the proposed Issue Date;

<PAGE>
                                       7



     (d)  in the case of Notes which are intended to be listed, the relevant
          Stock Exchange having agreed to list such Notes;

     (e)  no meeting of the holders of Notes (or any of them) issued by the
          relevant Issuer (to consider matters which might in the reasonable
          opinion of the relevant Dealer be considered to have a material
          adverse effect on the issue of the Notes) having been duly convened
          but not yet held or, if held but adjourned, the adjourned meeting
          having not been held and neither the relevant Issuer nor the
          Guarantor being aware of any circumstances which are likely to lead
          to the convening of such a meeting;

     (f)  there having been, between the Agreement Date and the Issue Date for
          such Notes, no such change in national or international financial,
          political or economic conditions or currency exchange rates or
          exchange controls as would, in the opinion of the relevant Dealer
          (after consultation with the relevant Issuer and the Guarantor if
          practicable), be likely to prejudice materially the success of the
          offer, sale or distribution by such Dealer of the Notes proposed to
          be issued;

     (g)  the forms of the Pricing Supplement, the Temporary Global Note, the
          Permanent Global Note and/or the Definitive Notes in relation to the
          relevant Tranche and the relevant settlement procedures, having been
          agreed by the relevant Issuer, the Guarantor, the relevant Dealer
          and the Agent;

     (h)  the relevant currency being generally accepted for settlement by
          Euroclear and Clearstream, Luxembourg; and

     (i)  any calculations or determinations which are required by the
          relevant Conditions prior to the Issue Date having been duly made.

(3)  Waiver

     Any Dealer, on behalf of itself only (or, in relation to a syndicated
     issue, the Lead Manager on behalf of itself and the other Managers) may
     by notice in writing to the relevant Issuer and the Guarantor waive any
     of the conditions precedent contained in subclauses (1) and (2) (save for
     the condition precedent contained in subclause (2)(c)) in so far as they
     relate to an issue of Notes to that Dealer.


<PAGE>
                                       8



(4)  Updating of legal opinions

     Before the first issue of Notes occurring after the end of each annual
     period commencing on the date hereof and on such other occasions as a
     Dealer so requests in relation either to any Issuer or the Guarantor or
     both (on the basis of reasonable grounds), the Issuers and/or the
     Guarantor will procure that a further legal opinion in such form and with
     such content as the Dealers may reasonably require is delivered, at the
     expense of the Issuers (as to which each of the Issuers shall have joint
     and several responsibility as between itself and the Guarantor to the
     Dealers). If at, or prior to, the time of any agreement to issue and
     purchase Notes under Clause 2 such request is given in writing with
     respect to the Notes to be issued, the receipt of such opinion in a form
     satisfactory to the relevant Dealer shall be a further condition
     precedent to the issue of those Notes to the relevant Dealer.

(5)  Determination of amounts outstanding

     For the purposes of subclause (2)(c):

     (a) the U.S. dollar equivalent of Notes denominated in a currency other
     than U.S. dollars shall be determined, at the discretion of the Issuer,
     either as of the Agreement Date for such Notes or on the preceding day on
     which commercial banks and foreign exchange markets are open for general
     business in London, in each case on the basis of the spot rate for the
     sale of U.S. dollars against the purchase of the relevant currency in the
     London foreign exchange market quoted by any leading bank selected by the
     relevant Issuer or the Guarantor on the relevant day of calculation;

     (b) the U.S. dollar equivalent of Dual Currency Notes and Indexed Notes
     shall be calculated in the manner specified above by reference to the
     original nominal amount of such Notes;

     (c) the U.S. dollar equivalent of Zero Coupon Notes and other Notes
     issued at a discount or premium shall be calculated in the manner
     specified above by reference to the net proceeds received by the relevant
     Issuer for the particular issue; and

     (d) the U.S. dollar equivalent of Partly Paid Notes shall be the nominal
     amount regardless of the amount of purchase moneys paid.

4.   Representations and Warranties

     (e)  that, except as disclosed in the Offering Circular, none of the
          Issuers or the Guarantor is engaged (whether as defendant or
          otherwise) in, nor has any of the Issuers or the Guarantor knowledge
          of the existence of, or any threat of, any legal, arbitration,
          administrative or other proceedings the result of which might have a

(2)  With regard to each issue of Notes under the Program, the relevant Issuer
     and the Guarantor shall be deemed to repeat the warranties and agreements
     contained in subclause (1) as at the Agreement Date for such Notes (any
     agreement on such Agreement Date being deemed to have been made on the
     basis of, and in reliance on, such warranties and agreements) and as at
     the Issue Date of such Notes.

(3)  The Issuers and the Guarantor shall be deemed to repeat the
     representations and warranties contained in subclause (1)(a) on each date
     on which the Offering Circular is revised, supplemented or amended. The
     Issuers and the Guarantor shall be deemed to repeat the representations
     and warranties contained in subclause (1) on each date on which the
     aggregate nominal amount of the Program is increased in accordance with
     Clause 12. (4) The warranties and agreements contained in this Clause 4
     shall continue in full force and effect notwithstanding any investigation
     by or on behalf of the Dealers or completion of the subscription and
     issue of any Notes.

5.   Undertakings of the Issuers and the Guarantor

(1)  Notification of material developments

     Each Issuer and the Guarantor shall, prior to the time of an agreement
     under Clause 2 (or, if such party becomes aware of the occurrence thereof
     after such time but prior to the completion of the distribution by the
     Dealers of the relevant Notes, promptly upon becoming aware of the
     occurrence thereof), notify each Dealer of:

     (a)  any Event of Default or any condition, event or act in relation to
          itself of which it is aware which, with the giving of notice and/or
          the lapse of time (after the issue of any Notes) would constitute an
          Event of Default or any breach of the representations and warranties
          or undertakings contained in this Agreement, the Agency Agreement,
          the Deed of Covenant, the Deed of Guarantee or any of them; and

     (b)  any development affecting such Issuer or the Guarantor or their
          respective businesses of which it is aware which, in the reasonable
          opinion of such Issuer or the Guarantor (as the case may be), is
          material in the context of the Program or any issue of Notes
          thereunder.

     If, following the time of an agreement under Clause 2 and before the
     issue of the relevant Notes, the relevant Issuer or the Guarantor becomes
     aware that the conditions specified in Clause 3(2) will not be satisfied
     in relation to that issue, the relevant Issuer or the Guarantor (if
     applicable), as the case may be, shall forthwith notify the relevant
     Dealer to that effect giving full details thereof. In such circumstances,
     the relevant Dealer shall be entitled (but not bound) by written notice
     to the relevant Issuer and the Guarantor to be released and discharged
     from its obligations under the agreement reached under Clause 2. Without
     prejudice to the generality of the foregoing, each Issuer and the
     Guarantor shall from time to time promptly furnish to each Dealer such
     information relating to such Issuer and/or the Guarantor (as the case may
     be) as such Dealer may reasonably request, provided that such information
     is relevant in the context of the Program or an issue of Notes
     thereunder.

(2)  Updating of Offering Circular


<PAGE>
                                       12



     Following the publication of the Guarantor's audited financial
     information for the year ended 31st December, 2000, and at the end of
     each annual period thereafter and in the event of a change in the
     condition of any or all of the Issuers or the Guarantor which is material
     in the context of the Program or the issue of the Notes thereunder, the
     Issuers and the Guarantor shall update or amend the Offering Circular
     (following consultation with the Arrangers on behalf of the Dealers) by
     the publication of a supplement thereto, in a form approved by the
     Dealers, in the light of such change in condition. The Offering Circular
     shall, as specified therein, be deemed to incorporate by reference
     therein the most recently published annual accounts (if any) of each
     Issuer and the Guarantor and the most recently published annual report of
     the Guarantor from time to time. Upon any new financial statements being
     incorporated in the Offering Circular as aforesaid or upon the
     publication of a revised Offering Circular or a supplement to the
     Offering Circular, the Issuers or the Guarantor (as the case may be)
     shall promptly supply to each Dealer and the Agent such number of copies
     of such financial statements, revised Offering Circular or supplement as
     each Dealer or the Agent (as the case may be) may reasonably request.
     Until a Dealer receives such financial statements, revised Offering
     Circular or supplement, the definition of "Offering Circular" in Clause
     1(1) shall, in relation to such Dealer, mean the Offering Circular prior
     to the publication of such financial statements, revised Offering
     Circular or supplement.

(3)  Listing

     The Issuers and the Guarantor shall cause an initial application to be
     made for Notes issued under the Program to be listed on the Luxembourg
     Stock Exchange or on such other Stock Exchange as the Issuers, the
     Guarantor and the Arrangers may agree. In connection with such
     application in respect of any Series of Notes which is intended to be so
     listed, the relevant Issuer and the Guarantor (if applicable) shall
     endeavour to obtain the listing as promptly as reasonably practicable and
     the relevant Issuer and the Guarantor (if applicable) shall make
     reasonable endeavours to furnish any and all documents, instruments,
     information and undertakings that may be necessary or advisable in order
     to obtain and maintain the listing. If, after the preparation of the
     Offering Circular for submission to the relevant Stock Exchange and
     before whichever is the later of the Issue Date of any Notes and the date
     on which listing becomes effective:

     (a)  there is a significant change which is material in the context of
          the Notes affecting any matter contained in the Offering Circular
          whose inclusion was required by the relevant Stock Exchange; or

     (b)  a significant new matter arises which is material in the context of
          the Notes and the inclusion of information in respect of which would
          have been so required if it had arisen when the Offering Circular
          was prepared,

     the relevant Issuer and the Guarantor shall give to the Listing Agent and
     to each Dealer full information about the change or matter and shall
     publish such supplementary listing particulars (in a form approved by the
     Listing Agent) as may be required by the relevant Stock Exchange, and
     shall otherwise comply with the Listing Rules in that regard.

     Each Issuer and the Guarantor shall comply with any undertakings given by
     it from time to time to the relevant Stock Exchange(s) in connection with
     any Notes listed on such Stock


<PAGE>
                                       13



     Exchange(s) or the listing thereof and, without prejudice to the
     generality of the foregoing, shall furnish or procure to be furnished to
     the relevant Stock Exchange(s) all such information as the relevant Stock
     Exchange(s) may require in connection with the listing on such Stock
     Exchange(s) of any Notes.

     If any Notes cease to be listed on the relevant Stock Exchange, the
     relevant Issuer and the Guarantor shall endeavour promptly to list such
     Notes on a stock exchange to be agreed between the Issuers, the Guarantor
     and the relevant Dealers.

(4)  Agency Agreement, Deed of Covenant and Deed of Guarantee

     Each Issuer and the Guarantor undertakes that it will not:

     (a)  without prior consultation with the Dealers terminate the Agency
          Agreement, the Deed of Covenant or the Deed of Guarantee or effect
          or permit to become effective any amendment to the Agency Agreement,
          the Deed of Covenant or the Deed of Guarantee which, in the case of
          an amendment, would or might adversely affect the interests of any
          Dealer or of any holder of Notes issued before the date of such
          amendment; or

     (b)  without prior consultation with the Dealers appoint a different
          Agent or paying agent(s) under the Agency Agreement,

     and each Issuer and the Guarantor will promptly notify each of the
     Dealers of any termination of, or amendment to, the Agency Agreement, the
     Deed of Covenant or the Deed of Guarantee and of any change in the Agent
     or paying agent(s) under the Agency Agreement.

(5)  Lawful compliance

     Each Issuer and the Guarantor will at all times ensure that all necessary
     action is taken and all necessary conditions are fulfilled (including,
     without limitation, the obtaining of all necessary consents) so that it
     may lawfully comply with its obligations under the Notes, this Agreement,
     the Agency Agreement, the Deed of Covenant and the Deed of Guarantee and,
     further, so that it may comply with any applicable laws, regulations and
     guidance from time to time promulgated by any governmental and regulatory
     authorities relevant in the context of the issue of Notes under the
     Program.

(6)  Authorised representative

     Each Issuer and the Guarantor will notify the Dealers immediately in
     writing if any of the persons named in the list referred to in paragraph
     3 of the Initial Documentation List ceases to be authorised to take
     action on behalf of such Issuer and the Guarantor or if any additional
     person becomes so authorised together, in the case of an additional
     authorised person, with evidence satisfactory to the Dealers that such
     person has been so authorised.

(7)  Auditors' comfort letters

     Each Issuer and the Guarantor will at the time of the preparation of the
     initial Offering Circular and thereafter upon each occasion when the same
     may be amended or updated,


<PAGE>
                                       14



     whether by means of information incorporated by reference or otherwise
     (insofar as such amendment or up-dating concerns or contains financial
     information about any of the Issuers or the Guarantor), at the expense of
     the Issuers and the Guarantor (as to which each of the Issuers will have
     joint and several responsibility as between itself and the Guarantor) and
     at other times whenever so requested by the Dealers or any of them (on
     the basis of reasonable grounds) deliver to the relevant Dealer a comfort
     letter or comfort letters from independent auditors of the Issuers (or
     any of them) and the Guarantor in such form and with such content as the
     relevant Dealer may reasonably request.

(8)  No other issues

     During the period commencing on an Agreement Date in respect of any Notes
     and ending on the Issue Date with respect to those Notes, none of the
     Issuers or the Guarantor will, without prior consultation with the
     relevant Dealer, issue or agree to issue any other listed notes, bonds or
     other securities of whatsoever nature (other than Notes to be issued
     under the Program) where such notes, bonds or other securities would have
     the same maturity and currency as the Notes to be issued on the relevant
     Issue Date.

(9) Information on Noteholders' meetings

     Each Issuer or the Guarantor will, at the same time as it is despatched,
     furnish the Dealers with a copy of every notice of a meeting of the
     holders of the Notes (or any of them) which is despatched at the
     instigation of the relevant Issuer or the Guarantor (as the case may be)
     and will notify the Dealers immediately after it becomes aware that a
     meeting of the holders of the Notes (or any of them) has been convened by
     holders of the Notes.

(10) Rating

     Each Issuer (failing whom the Guarantor) undertakes promptly to notify
     the Dealers of any change in the rating given by Standard & Poor's,
     Moody's or such other rating agency as notified to the Dealers for any of
     the Notes to be issued under the Program by it, or upon it becoming aware
     that such rating is listed on 'Creditwatch' or other similar publication
     of formal review by the relevant rating agency.

6.   Indemnity

(1)  Without prejudice to the other rights or remedies of the Dealers, each of
     the Issuers (severally as to itself) and the Guarantor (jointly and
     severally with the relevant Issuer and severally as to itself),
     undertakes with the Dealers and each of them that it will hold each
     Indemnified Person indemnified against any losses, liabilities, claims,
     charges, actions or demands, and any reasonable out of pocket costs and
     expenses, which they may incur or which may be against them as a result
     of or in relation to:

     (a)  any failure by the relevant Issuer to issue on the agreed Issue Date
          any Notes which a Dealer has agreed to purchase (unless such failure
          is as a result of the failure by the relevant Dealer to pay the
          aggregate purchase price for such Notes); or

     (b)  any actual or alleged breach of the representations and warranties
          and undertakings by such Issuer and/or, as applicable, the Guarantor
          contained in, or made or deemed to


<PAGE>
                                       15



          be made pursuant to, this Agreement (any such allegation being made
          by a person other than an Indemnified Person); or

     (c)  any untrue or misleading (or allegedly untrue or misleading)
          statement, which is material (or allegedly material) in the context
          of the Program and the issue and offering of Notes by such Issuer
          thereunder, in, or material omission (or alleged omission) from, the
          Offering Circular or any part thereof (any such allegation being
          made by a person other than an Indemnified Person).

(2)  If any action, proceeding, claim or demand shall be brought or asserted
     against any Indemnified Person in respect of which an indemnity is to be
     sought against another party under Clause 6(1) (the "Indemnifying
     Person"), the Indemnified Person shall promptly notify the Indemnifying
     Person in writing, and the Indemnifying Person shall have the option in
     the name of the Indemnified Person to assume the defence thereof,
     including the employment of legal advisers approved by the Indemnified
     Person (which approval shall not be unreasonably withheld or delayed)
     subject to the payment by the Indemnifying Person of all fees and
     expenses relating thereto provided that such legal advisers shall not,
     save with the consent of the Indemnified Person (which consent shall not
     be unreasonably withheld or delayed), also be legal advisers to the
     Indemnifying Person and provided further that if the defendants in any
     such action, proceeding, claim or demand include the Indemnified Person
     and the Indemnified Person shall have reasonably concluded that there may
     be legal defences available to the Indemnified Person which are different
     from or additional to those available to the Indemnifying Person and in
     the event that the Indemnifying Person does not wish to assume, or is
     prevented from assuming, such different or additional legal defences on
     behalf of the Indemnified Person, the Indemnified Person shall have the
     right, at the expense of the Indemnifying Person, to select separate
     legal advisers to assume such legal defences and otherwise to participate
     in the defence of such action, proceeding, claim or demand on behalf of
     the Indemnified Person.

     Upon receipt of notice from the Indemnifying Person of its election so to
     assume the defence of any such action, proceeding, claim or demand and
     approval by the Indemnified Person as aforesaid of legal advisers, the
     Indemnifying Person will not be liable to any Indemnified Person for any
     fees or expenses subsequently incurred by such Indemnified Person in
     connection with the defence thereof unless:

     (i)  the Indemnified Person shall have employed legal advisers in
          connection with the assumption of legal defences in accordance with
          the proviso to the preceding paragraph; or

     (ii) the Indemnifying Person shall not have employed legal advisers, or
          taken other measures, approved by or on behalf of the Indemnified
          Person to represent such Indemnified Person within a reasonable time
          after notice has been received by the Indemnifying Person of
          commencement of the action or proceedings or the making of any claim
          or demand; or

     (iii) the Indemnifying Person has authorised the employment of separate
          legal advisers by the Indemnifying Person,


<PAGE>
                                       16



          in which case the Indemnifying Person will reimburse the relevant
          Indemnified Person all such reasonable fees and expenses.

          Each Indemnified Person undertakes not to compromise or settle any
          such action, proceedings, claim or demand effected without the
          written consent of the Indemnifying Person. Each Indemnifying Person
          undertakes not to compromise or settle any such action, proceedings,
          claims or demands effected without the written consent of the
          Indemnified Person (consent is not to be unreasonably withheld or
          delayed). If any such action, proceeding, claim or demand shall be
          settled with the authority and written consent of the Indemnifying
          Person or if there be a final judgment for the plaintiff in relation
          thereto in respect of which the Indemnified Person is entitled to
          indemnification hereunder, the Indemnifying Person agrees to
          indemnify and hold harmless the Indemnified Person from and against
          any loss or liability by reason of such settlement or judgment
          (other than any fees and expenses incurred in circumstances where
          the Indemnifying Person is not to be liable therefor under the
          preceding paragraph).

7.   Authority to Distribute Documents

     Subject to Clause 8 below, each Issuer and the Guarantor hereby
     authorises each of the Dealers on behalf of each Issuer and the Guarantor
     to provide copies of the Offering Circular and such additional written
     information as the relevant Issuer or the Guarantor shall, in writing,
     provide to and authorise the Dealers so to use to actual and potential
     purchasers of Notes.

8.   Dealers' Undertakings

(1)  Each Dealer agrees to comply with the restrictions and agreements set out
     in Appendix B hereto.

(2)  Each Dealer acknowledges that:

     (i)  none of the Issuers nor the Guarantor has authorised it to give any
          information or make any representation in connection with any
          offering, issue, subscription or sale of any Notes other than those
          contained in the Offering Circular or the information approved in
          writing and provided by such Issuer or the Guarantor pursuant to
          Clause 7;

     (ii) it will not circulate any version of the Offering Circular other
          than the latest version of the Offering Circular published by such
          Issuer and made available to such Dealer from time to time; and

     (iii) it shall promptly cease use or distribution of the Offering
          Circular or any additional written information provided for in
          Clause 7 upon receipt of notice from any Issuer or the Guarantor
          that the Offering Circular or such information requires updating or
          correction.

(3)  Each Dealer undertakes with each of the Issuers, the Guarantor and the
     other Dealers to indemnify, defend and hold harmless the Indemnified
     Person against any losses, liabilities, claims, charges, actions and
     demands, and any reasonable out-of-pocket costs and expenses which the
     Indemnified Person may incur or which may be made against the Indemnified
     Person arising out of, or in connection with:

<PAGE>
                                       17



     (a)  the making by such Dealer of any unauthorised representation or the
          giving by it of any information which is not contained in the
          Offering Circular or otherwise authorised in accordance with Clause
          7; or

     (b)  any failure by such Dealer to observe any of the restrictions or
          agreements contained in Appendix B hereto.

(4)  If any claim, demand or action is brought against any such Indemnified
     Person in respect of which indemnity may be sought from a Dealer pursuant
     to Clause 8(3), the provisions of Clause 6(2) shall apply, mutatis
     mutandis, in relation thereto.

9.   Fees, Expenses and Stamp Duties

(1)  The Issuers and the Guarantor jointly and severally undertake that they
     shall:

     (a)  pay to each Dealer all commissions from time to time agreed in
          connection with the sale of any Notes to that Dealer (and any value
          added or other similar tax thereon); and

     (b)  pay (together with any value added tax or other similar tax
          thereon):

          (i)  the fees and expenses of their legal advisers and auditors; and

          (i)  the fees and expenses payable to the Agent and any paying
               agents;

          (ii) all expenses (other than those of the Agent, any paying agent
               or the Dealers) in connection with the issue, authentication,
               packaging and initial delivery of Notes and the preparation of
               Global Notes, this Agreement, the Agency Agreement, the Deed of

          to the fees and disbursements of the legal advisers appointed to

<PAGE>
                                       18

          Agreement, any communication pursuant hereto, the Agency Agreement,
          the Deed of Covenant, the Deed of Guarantee or any Note and shall
          indemnify each Dealer against any liability with respect to or
          resulting from any delay in paying or omission to pay any such duty
          or tax.

10.  Termination of Appointment of Dealers

     The Issuers, the Guarantor or (as to itself) a Dealer may terminate the
     arrangements described in this Agreement by giving not less than 30 days'
     written notice to the other parties hereto. The Issuers or the Guarantor
     may terminate the appointment of a Dealer or Dealers by giving not less
     than 30 days' written notice to such Dealer or Dealers (with a copy
     promptly thereafter to all the other Dealers and the Agent). Termination
     shall not affect any rights or obligations (including but not limited to
     those arising under Clause 6, 8 or 9) which have accrued at the time of
     termination or which accrue thereafter in relation to any act or omission
     or alleged act or omission which occurred prior to such time.

11.  Appointment of New Dealers

(1)  Nothing in this Agreement shall prevent the Issuers or the Guarantor from
     appointing one or more New Dealers for the duration of the Program or,
     with regard to a particular issue of Notes, the relevant Issuer and the
     Guarantor (if applicable) from appointing one or more New Dealers for the
     purposes of that issue, in either case upon the terms of this Agreement
     and provided that, unless such appointment is effected pursuant to a
     Subscription Agreement:

     (a)  any New Dealer shall have first delivered to the Issuers and the
          Guarantor a Dealer Accession Letter; and

     (b)  the Issuers and the Guarantor shall have delivered to such New
          Dealer a Confirmation Letter.

     Upon receipt of the relevant Confirmation Letter or execution of the
     relevant Subscription Agreement, as the case may be, each such New Dealer
     shall, subject to the terms of the relevant Dealer Accession Letter and
     the relevant Confirmation Letter or the relevant Subscription Agreement,
     as the case may be, become a party to this Agreement, vested with all
     authority, rights, powers, duties and obligations of a Dealer as if
     originally named as a Dealer hereunder provided that, except in the case
     of the appointment of a New Dealer for the duration of the Program,
     following the issue of the Notes of the relevant Tranche, the relevant
     New Dealer shall have no further such authority, rights, powers, duties
     or obligations except such as may have accrued or been incurred prior to
     or in connection with the issue of such Notes.

<PAGE>
                                       19



(2)  The Issuers and/or the Guarantor shall promptly notify the Agent and the
     other Dealers of any appointment of a New Dealer for the duration of the
     Program by supplying to such parties a copy of any Dealer Accession
     Letter and Confirmation Letter. No such notice shall be required to be
     given in the case of an appointment of a New Dealer for a particular
     issue of Notes.

12.  Increase in the Aggregate Nominal Amount of the Program

(1)  From time to time the Issuers and the Guarantor may wish to increase the
     aggregate nominal amount of the Notes that may be issued under the
     Program. In such circumstances, the Issuers and the Guarantor may request
     such an increase (subject as set out in subclause (2)) by delivering to
     the Listing Agent and the Dealers the letter substantially in the form
     set out in Appendix D hereto. Unless notice to the contrary is received
     by the Issuers or the Guarantor no later than 10 days after notice was
     given to the Dealers and the Listing Agent, each such Dealer and the
     Listing Agent will be deemed to have given its consent to the increase in
     the nominal amount of the Program, whereupon all references in this
     Agreement and the Procedures Memorandum to a Euro Medium Term Note
     Program of a certain nominal amount, shall be and shall be deemed to be
     references to a Euro Medium Term Note Program of the increased nominal
     amount.

(2)  Notwithstanding subclause (1), the right of the Issuers and the Guarantor
     to increase the aggregate nominal amount of the Program shall be subject
     to each Dealer having received and found satisfactory all the documents
     and confirmations described in the Initial Documentation List (with such
     changes as may be relevant, with reference to the circumstances at the
     time of the proposed increase as are agreed between the Issuers, the
     Guarantor and the Dealers), and the delivery of any further conditions
     precedent that any of the Dealers may reasonably require, including,
     without limitation, the production of a supplementary Offering Circular
     by the Issuers and the Guarantor and any further or other documents
     required by the relevant Stock Exchange(s) for the purpose of listing the
     Notes to be issued under the Program on the relevant Stock Exchange(s).
     The Arrangers shall circulate to the Dealers all the documents and
     confirmations described in the Initial Documentation List and any further
     conditions precedent so required. Any Dealer must notify the Arrangers,
     the Issuers and the Guarantor within 10 business days of receipt if it
     considers, in its reasonable opinion, such documents, confirmations and,
     if applicable, such further conditions precedent to be unsatisfactory.

13.  Status of the Arrangers

(1)  Each of the Dealers agrees that each Arranger has only acted in an
     administrative capacity to facilitate the establishment and/or
     maintenance of the Program and has no responsibility to it for (a) the
     adequacy, accuracy, completeness or reasonableness of any representation,
     warranty, undertaking, agreement, statement or information in the
     Offering Circular, any Pricing Supplement, this Agreement or any
     information provided in connection with the Program or (b) the nature and
     suitability of it of all legal, tax and accounting matters and all
     documentation in connection with the Program or any Tranche.

(2)  The Arrangers shall have only those duties, obligations and
     responsibilities expressly specified in this Agreement.

14.  Counterparts

     This Agreement may be signed in any number of counterparts, all of which
     taken together shall constitute one and the same instrument.

15.  Communications

(1)  All communications shall be by fax or letter delivered by hand or (but
     only where specifically provided in the Procedures Memorandum) by
     telephone. Each communication shall be made to the relevant party at the
     fax number or address or telephone number and, in the case of a
     communication by fax or letter, marked for the attention of, or (in the
     case of a communication by telephone) made to, the person(s) from time to
     time specified in writing by that party to the other for the purpose. The
     initial telephone number, fax number and address of, and person(s) so
     specified by, each party are set out on the signature pages hereof.

(2)  A communication shall be deemed received (if by fax) when an
     acknowledgement of receipt is received, (if by telephone) when made or
     (if by letter) when delivered, in each case in the manner required by
     this clause. Every communication shall be irrevocable save in respect of
     any manifest error therein.

16.  Benefit of Agreement

(1)  This Agreement shall be binding upon and shall inure for the benefit of
     each Issuer, the Guarantor and each Dealer and their respective
     successors and permitted assigns.

(2)  The Dealers may assign or transfer their rights or obligations under this
     Agreement with the prior written consent of the Issuers and the
     Guarantor. If the Dealers assign their rights or transfer their
     obligations as provided in this clause, the relevant assignee or
     transferee shall be treated as if it were a party to this Agreement with
     effect from the date on which such assignment or transfer takes effect;
     provided that any transfer shall only become effective when the Issuers
     and the Guarantor have received an undertaking from the transferee to be
     bound by this Agreement and to perform the obligations transferred to it
     (in form and substance reasonably satisfactory to the Issuers and the
     Guarantor).

17.  Currency Indemnity

     If, under any applicable law and whether pursuant to a judgment being
     made or registered against any Issuer and/or (as the case may be) the
     Guarantor or in the liquidation, insolvency or analogous process of the
     relevant Issuer and/or (as the case may be) the Guarantor or for any
     other reason, any payment under or in connection with this Agreement is
     made or falls to be satisfied in a currency (the "other currency") other
     than that in which the relevant payment is expressed to be due (the
     "required currency") under this Agreement, then, to the extent that the
     payment (when converted into the required currency at the rate of
     exchange on the date of payment or, if it is not practicable for the
     relevant Dealer to purchase the required currency with the other currency
     on the date of payment, at the rate of exchange as soon thereafter as it
     is practicable for it to do so) actually received by the relevant Dealer
     falls short of the amount each due under the terms of this Agreement, the
     relevant Issuer and the Guarantor each undertakes that it shall, as a
     separate and independent obligation, indemnify and hold harmless each
     Dealer against the amount of such shortfall. For the purpose of this


<PAGE>
                                       21



     clause "rate of exchange" means the rate at which the relevant Dealer is
     able on the London foreign exchange market on the relevant date to
     purchase the required currency with the other currency and shall take
     into account any premium and other reasonable costs of exchange. The
     Dealers understand and agree that in the event that the required currency
     is replaced by the Euro after the date hereof, the Euro will not be
     considered an "other currency" for the purposes of this Clause 17.

18.  Calculation Agent

(1)  In the case of any Series of Notes which require the appointment of a
     Calculation Agent the Agent shall act as Calculation Agent, unless (a)
     the relevant Issuer or the Guarantor appoints another person as
     Calculation Agent with the approval of the relevant Dealer or (in the
     case of a syndicated issue) the Lead Manager or (b) the relevant Dealer
     or (in the case of a syndicated issue) the Lead Manager requests the
     relevant Issuer to appoint such Dealer or Lead Manager, or a person
     nominated by such Dealer or Lead Manager (a "Nominee"), as Calculation
     Agent.

(2)  Should such an appointment be made by the relevant Issuer or Guarantor
     (with such approval) or such a request be made to the relevant Issuer and
     agreed to by the relevant Issuer and the Guarantor, the appointment of
     that other person, Dealer, Lead Manager or Nominee shall be automatic
     upon the issue of the relevant Series of Notes, and shall, except as
     agreed, be on the terms set out in the Calculation Agency Agreement
     attached as Appendix A to the Agency Agreement, and no further action
     shall be required to effect the appointment of such Dealer, other person,
     Lead Manager or Nominee as Calculation Agent in relation to that Series
     of Notes. The name of the other person, Dealer, Lead Manager or Nominee
     so appointed will be entered in the relevant Pricing Supplement.

19.  Stabilisation

     In connection with the distribution of any Tranche of Notes, the Dealer
     (if any) designated as stabilising manager in the applicable Pricing
     Supplement may over-allot or effect transactions which stabilise or
     maintain the market price of Notes of the Series of which such Tranche
     forms a part at a level which might not otherwise prevail, but in doing
     so such Dealer shall act as principal and not as agent of the relevant
     Issuer. Such stabilising, if commenced, may be discontinued at any time.
     Any loss resulting from over-allotment and stabilisation shall be borne,
     and any net profit arising therefrom shall be retained, by the
     stabilising manager for its own account. Such stabilising shall be done
     in accordance with the applicable laws.

20.  Governing Law and Jurisdiction

(1)  This Agreement and every agreement for the issue and purchase of Notes as
     referred to in Clause 2 shall be governed by, and construed in accordance
     with, the laws of England.

(2)  This Agreement does not create any right under the Contracts (Rights of
     Third Parties) Act 1999 which is enforceable by any person who is not a
     party to this Agreement.

(3) Each party to this Agreement hereby irrevocably agrees for
     the exclusive benefit of the other parties to this Agreement that the
     courts of England are to have jurisdiction to settle any disputes which
     may arise out of or in connection with this Agreement and that
     accordingly any

<PAGE>
                                       22



     suit, action or proceedings (together referred to as "Proceedings")
     arising out of or in connection with this Agreement may be brought in
     such courts. Each party to this Agreement hereby irrevocably waives any
     objection which it may have to the laying of the venue of any Proceedings
     in any such courts and any claim that any such Proceedings have been
     brought in an inconvenient forum and hereby further irrevocably agrees
     that a judgment in any Proceedings brought in the English courts shall be
     conclusive and binding upon such party and may be enforced in the courts
     of any other jurisdiction (subject to the laws of the jurisdiction in
     which enforcement is sought). Nothing contained herein shall limit any
     right to take Proceedings against any party to this Agreement in any
     other court of competent jurisdiction (outside the Contracting States as
     defined in Section 1(3) of the Civil Jurisdiction and Judgments Act
     1982), nor shall the taking of Proceedings in one or more jurisdictions
     preclude the taking of Proceedings in any other jurisdiction, whether
     concurrently or not (subject to the laws of the relevant jurisdictions).
     Each of CSC US, CSC Germany and the Guarantor hereby appoints CSC UK as
     its agent for service of process and agrees that, in the event of ceasing
     so to act or ceasing to be registered in England, it will appoint another
     person as its agent for service of process in England in respect of any
     Proceedings.

IN WITNESS WHEREOF the parties hereto have executed this Agreement as of the
date first above written.

                                  APPENDIX B

                             SELLING RESTRICTIONS

1.   United States

(1)  The Notes have not been and will not be registered under the Securities
     Act of 1933, as amended (the "Securities Act"), and may not be offered or
     sold within the United States or to, or for the account or benefit of,
     U.S. persons except in accordance with Regulation S under the Securities
     Act or pursuant to an exemption from the registration requirements of the
     Securities Act. Each Dealer represents and agrees that it and any of its
     affiliates and any person acting on its or their behalf have offered and
     sold any Notes, and will offer and sell any Notes (i) as part of their
     distribution at any time and (ii) otherwise until 40 days after the
     completion of the distribution of all Notes of the Tranche of which such
     Notes are a part, as determined and notified by the Agent to such Dealer,
     as provided below, only in accordance with Rule 903 of Regulation S under
     the Securities Act. Accordingly, each Dealer, its affiliates and any
     persons acting on its or their behalf have not engaged and will not
     engage in any directed selling efforts with respect to the Notes, and
     have complied and will comply with the offering restrictions requirement
     of Regulation S. Each Dealer who has purchased Notes of a Tranche
     hereunder (or in the case of a sale of a Tranche of Notes issued to or
     through more than one Dealer, each of such Dealers as to the Notes of
     such Tranche purchased by or through it) shall determine and certify to
     the Agent the completion of the distribution of the Notes of such
     Tranche. On the basis of such certification or certifications, the Agent
     agrees to notify such Dealer or Dealers of the end of the distribution
     compliance period with respect to such Tranche. Each Dealer also agrees
     that, at or prior to confirmation of sale of Notes, it will have sent to
     each distributor, dealer or person receiving a selling concession, fee or
     other remuneration that purchases Notes from it or any of its affiliates
     or any person acting on its or their behalf during the distribution
     compliance period a confirmation or notice to substantially the following
     effect:

          "The Securities covered hereby have not been registered under the
          U.S. Securities Act of 1933 (the "Securities Act") and may not be
          offered or sold within the United States or to, or for the account
          or benefit of, U.S. persons (i) as part of their distribution at any
          time or (ii) otherwise until 40 days after the completion of the
          distribution of the Securities as determined and notified by the
          Agent for the Securities to [name of Dealer(s)], except in either
          case in accordance with Regulation S under the Securities Act. Terms
          used above have the meanings given to them by Regulation S."

     Terms used in this sub-clause 1(1) have the meanings given to them by
     Regulation S.

(2)  In addition:

     (1)  except to the extent permitted under U.S. Treas. Reg. Section
          1.163-5(c)(2)(i)(D) (the "D Rules"), each Dealer (a) represents that
          it has not offered or sold, and agrees that during the restricted
          period it will not offer or sell, Notes in bearer form to a person
          who is within the United States or its possessions or to a United
          States person, and (b) represents that it has not delivered and
          agrees that it will not deliver within the

<PAGE>
                                       26



          United States or its possessions definitive Notes in bearer form
          that are sold during the restricted period;

     (2)  each Dealer represents that it has and agrees that throughout the
          restricted period it will have in effect procedures reasonably
          designed to ensure that its employees or agents who are directly
          engaged in selling Notes in bearer form are aware that such Notes
          may not be offered or sold during the restricted period to a person
          who is within the United States or its possessions or to a United
          States person, except as permitted by the D Rules;

     (3)  if it is a United States person, each Dealer represents that it is
          acquiring the Notes for purposes of resale in connection with their
          original issuance and if it retains Notes in bearer form for its own
          account, it will only do so in accordance with the requirements of
          U.S. Treas. Reg. Section 1.163-5(c)(2)(i)(D)(6); and

     (4)  with respect to each affiliate that acquires Notes from a Dealer for
          the purpose of offering or selling such Notes during the restricted
          period, such Dealer repeats and confirms the representations and
          agreements contained in sub-clauses (1), (2) and (3) on such
          affiliate's behalf.

     Terms used in this sub-clause 1(2) have the meanings given to them by the
     U.S. Internal Revenue Code and regulations thereunder, including the D
     Rules.

(3)  Each Dealer represents that it has not entered and agrees that it will
     not enter into any contractual arrangement with respect to the
     distribution or delivery of Notes, so as to cause any person to become a
     "distributor" within the meaning of Regulation S or the D Rules except
     with their affiliates or with the prior written consent of the relevant
     Issuer and the Guarantor (in which case such Dealer will obtain for the
     benefit of the Issuer and the Guarantor the agreement of such person to
     the representations and agreements contained in Clauses 1(1) and 1(2)
     above).

(4)  Each issue of Indexed Notes and Dual Currency Notes shall be subject to
     such additional U.S. selling restrictions as the relevant Issuer and the
     relevant Dealer or Dealers shall agree as a term of the issue and
     purchase of such Notes, which additional selling restrictions shall be
     set out in the Pricing Supplement. Each Dealer agrees that it shall
     offer, sell and deliver such Notes only in compliance with such
     additional U.S. selling restrictions.

          whose ordinary activities involve them in acquiring, holding,
          managing or disposing of investments (as principal or agent) for the

          to whom such document may otherwise lawfully be issued or passed on;
          and

     (iii) it has complied and will comply with all applicable provisions of
          the FSA with respect to anything done by it in relation to any Notes

     any corporation or other entity organised under the laws of Japan), or to

     sold only in compliance with an exemption from the prospectus requirement
     of the German Securities Selling Prospectus Act
     (Wertpapier-Verkaufsprospektgesetz) of 13th December, 1990, as amended,
     and (ii) in any event Notes will be offered and sold in Germany only in
     accordance with the requirements of such Act.

5.   General

     all applicable laws and regulations in force in any jurisdiction in which
     it purchases, offers, sells or delivers Notes or possesses or distributes
     the Offering Circular and will obtain any consent, approval or permission
     required by it for the purchase, offer, sale or delivery by it of Notes
     under the laws and regulations in force in any jurisdiction to which it
     is subject or in which it makes such purchases, offers, sales or
     deliveries and none of the Issuers, the Guarantor nor any other Dealer
     shall have responsibility therefor.

     None of the Issuers, the Guarantor nor any of the Dealers represents that
     Notes may at any time lawfully be sold in compliance with any applicable
     registration or other requirements in any jurisdiction, or pursuant to
     any exemption available thereunder, or assumes any responsibility for
     facilitating such sale.

     With regard to each Tranche, the relevant Dealer will be required to
     comply with such other additional restrictions as the relevant Issuer,
     the Guarantor and the relevant Dealer shall agree and as shall be set out
     in the applicable Pricing Supplement.

*[1. Conditions Precedent

     This Agreement appoints each Manager which is not a party to the Program
     Agreement (each a "New Dealer") as a Dealer under the Program Agreement
     for the purposes of the issue of the Notes. The Lead Manager confirms
     that it is in receipt of the documents referenced below:

     (i)  a copy of the Program Agreement;

     (ii) a copy of all documents referred to in Appendix A of the Program
          Agreement; and

     (iii) a copy of the Agency Agreement;

     and has confirmed with (each of) the New Dealer(s) that it/they has/have

     For the purposes of the Program Agreement the details of the Lead Manager
     for service of notices are as follows:

     (insert name, address, telephone, telex (# answerback) and attention).

     In consideration of the Issuer and the Guarantor appointing the New
     Dealer(s) as (a) Dealer(s) in respect of the Notes under the Program
     Agreement, each/the New Dealer hereby undertakes, for the benefit of each
     of the Issuers, the Guarantor and the other Dealers, that, in relation to
     the issue of the Notes, it will perform and comply with all the duties
     and obligations expressed to be assumed by a Dealer under the Program
     Agreement, a copy of which it acknowledges it has received from the Lead
     Manager.]

     The Issuer hereby confirms that [each] [the] New Dealer shall be vested
     with all authority, rights, powers, duties and obligations of a Dealer in
     relation to the issue of Notes as if originally named as a Dealer under
     the Program Agreement provided that following the issue of the Temporary
     Global Note in respect of the Notes [each] [the] New Dealer shall have no
     further such authority, rights, powers, duties and obligations except
     such as may have accrued or been incurred prior to, or in connection
     with, the issue of such Temporary Global Note and the Notes represented
     thereby.


2.   Subject to the terms and conditions of the Program Agreement and this
     Agreement the Issuer hereby agrees to issue the Notes, the Guarantor
     hereby agrees to guarantee the Notes and the Managers jointly and
     severally agree to purchase the Notes at a subscription price of [ ] per

     at [ ] hours (London time) on [ ], or at such other time and/or date as
     the Issuer and the Lead Manager on behalf of the Managers may agree (the
     "Closing Date") against delivery to a common depositary for Clearstream,
     Luxembourg and Morgan Guaranty Trust Company of New York, Brussels
     Office, as operator of the Euroclear System, or any successor to the
     business thereof of a temporary global note representing the Notes, in
     the manner contemplated in the Program Agreement.

4.   The Issuer or, failing the Issuer, the Guarantor shall bear and pay all
     costs and expenses incurred in or in connection with the printing of the
     Notes, this Agreement and the Pricing Supplement prepared in connection
     with the issue of the Notes, the listing of the Notes on the [ ] Stock
     Exchange and making initial delivery of the Notes. In addition, the
     Issuer or, failing the Issuer, the Guarantor agrees to pay to the Lead
     Manager [ ] in respect of reasonable legal, travelling, telex, facsimile,
     telephone, postage and costs of any publicity agreed in writing by the
     Issuer or the Guarantor incurred and to be incurred by the Managers in
     connection with the preparation and management of the issue and
     distribution of the Notes which sum may be deducted from the Subscription
     Price as provided in Clause 3 hereof.

5.   The obligation of the Managers to purchase the Notes is conditional upon:

     (i)  the conditions set out in Clause 3(2) (other than that set out in
          Clause 3(2)(f)) of the Program Agreement being satisfied as of the
          Closing Date and without prejudice to the aforesaid, the Offering
          Circular dated [ ] [, as supplemented by [ ],] containing all
          material information relating to the assets and liabilities,
          financial position and profits and losses of the Issuer [and the
          Guarantor/Parent] and nothing having happened or being expected to
          happen which would require the Offering Circular [, as so
          supplemented,] to be [further] supplemented or updated; and

     (ii) the delivery to the Lead Manager on the Closing Date of:

          (A)  legal opinions addressed to the Managers dated the Closing Date
               in such form and with such contents as the Lead Manager, on
               behalf of the Managers, may reasonably require [from Bruckhaus
               Westrick Heller Lober/Cravath, Swaine & Moore], the legal
               advisers to the Issuer as to [German/United States law,] from
               Homburger Rechtsanwalte, the legal advisers to the Guarantor as
               to Swiss law, and from Allen & Overy, the legal advisers to the
               Managers as to English law;

          (B)  a certificate dated the Closing Date signed by a duly
               authorised officer of each of the Issuer and the Guarantor to
               the effect stated in paragraph (i) of this Clause;

          (C)  a comfort letter dated the Closing Date from the independent
               auditors of each of the Issuer and the Guarantor, in such form
               and with such content as the Managers may reasonably request;
               and

          (D)  [list such other conditions precedent as may be agreed].

     If any of the foregoing conditions is not satisfied on or before the
     Closing Date, this Agreement shall terminate on such date and the parties
     hereto shall be under no further


<PAGE>
                                       41



     liability arising out of this Agreement (except for the liability of the
     Issuer and the Guarantor in relation to expenses as provided in Clause 4
     and except for any liability arising before or in relation to such
     termination), provided that the Lead Manager, on behalf of the Managers,
     may in its discretion waive any of the aforesaid conditions (other than
     the conditions precedent contained in Clause 3(2)(c) of the Program
     Agreement) or any part of them.

6.   In connection with the distribution of the Notes, the Lead Manager may
     over-allot or effect transactions in the open market or otherwise with a
     view to stabilising or maintaining the market price of the Notes at
     levels other than those which might otherwise prevail in the open market,
     but in doing so the Lead Manager shall act as principal and not as agent
     of the Issuer. Such stabilising if commenced, may be discontinued at any
     time. Any loss resulting from over-allotment and stabilisation shall be
     borne, and any net profit arising therefrom shall be retained, by the
     Lead Manager for its own account. Such stabilisation shall be done in
     compliance with all applicable laws.

7.   (a)  The Lead Manager, on behalf of the Managers, may, after consultation
          with the Issuer and the Guarantor if practicable and by notice to
          the Issuer and the Guarantor, terminate this Agreement at any time
          prior to payment of the net purchase money to the Issuer if in the
          opinion of the Lead Manager there shall have been such a change in
          national or international financial, political or economic
          conditions or currency exchange rates or exchange controls as would
          in the view of the Lead Manager be likely to prejudice materially
          the success of the offering and distribution of the Notes (whether
          in the primary market or in respect of dealings in the Notes in the
          secondary market).

     (b)  Upon such notice being given, this Agreement shall terminate and no
          party shall be under any liability to any other in respect thereof
          except for the liability of the Issuer and the Guarantor for the
          payment of costs and expenses as provided in Clause 4 of this
          Agreement, the obligations of the Managers under Clause 8 of the
          Program Agreement and the respective obligations of the parties
          under Clause 6 of the Program Agreement.

8.   (1)  This Agreement shall be governed by, and construed in accordance
          with, the laws of England.

     (2)  This Agreement does not create any right under the Contracts (Rights
          of Third Parties Act 1999 which is enforceable by any person who is
          not a party to this Agreement)

     (3)  Each party to this Agreement hereby irrevocably agrees for the
          exclusive benefit of the other parties to this Agreement that the
          courts of England are to have jurisdiction to settle any disputes
          which may arise out of or in connection with this Agreement and that
          accordingly any suit, action or proceedings (together referred to as
          "Proceedings") arising out of or in connection with this Agreement
          may be brought in such courts. Each party to this Agreement hereby
          irrevocably waives any objection which it may have to the laying of
          the venue of any Proceedings in any such courts and any claim that
          any such Proceedings have been brought in an inconvenient forum and
          hereby further irrevocably agrees that a judgment in any Proceedings
          brought in the English courts shall be conclusive and binding upon
          such party and may be enforced in the courts of any other
          jurisdiction (subject to the laws of the jurisdiction in


<PAGE>
                                       42



          which enforcement is sought). Nothing contained herein shall limit
          any right to take Proceedings against the Issuer and/or the
          Guarantor in any other court of competent jurisdiction (outside the
          Contracting States, as defined in Section 1(3) of the Civil
          Jurisdiction and Judgments Act 1982), nor shall the taking of
          Proceedings in one or more jurisdictions preclude the taking of
          Proceedings in any other jurisdiction, whether concurrently or not
          (subject to the laws of the relevant jurisdiction). The [Issuer and
          the] Guarantor hereby appoints [the Issuer/Ciba Specialty Chemicals
          PLC] as its agent for service of process and agrees that, in the
          event of ceasing so to act or ceasing to be registered in England,
          it will appoint another person as its agent for service of process
          in England in respect of any Proceedings.

9.   This Agreement may be signed in any number of counterparts, all of which,
     taken together, shall constitute one and the same agreement and any party
     may enter into this Agreement by executing a counterpart.

                                  APPENDIX F

                           FORM OF DEED OF COVENANT

THIS DEED OF COVENANT is made on 16th June, 2000 by each of Ciba Specialty
Chemicals Corporation, Ciba Specialty Chemicals PLC and Ciba
Spezialitatenchemie Holding Deutschland GmbH (each an "Issuer") in favour of
the account holders of Clearstream Banking, societe anonyme ("Clearstream,
Luxembourg") and Morgan Guaranty Trust Company of New York, Brussels Office,
as operator of the Euroclear System, or any successor to the business thereof
or any other additional clearing system or systems as are specified in the
Pricing Supplement relating to any Note (as defined below) (each a "Clearing
System").

WHEREAS:

(A)  Each Issuer has entered into an amended and restated Program Agreement
     (the "Program Agreement", which expression includes the same as it may be
     amended or supplemented from time to time) dated 16th June, 2000 with
     Ciba Specialty Chemicals Holding Inc. (the "Guarantor") and the Dealers
     named therein under which the relevant Issuer proposes from time to time
     to issue Euro Medium Term Notes (the "Notes"), which amends and restates
     the amended and restated program agreement dated 9th July, 1999 with Ciba
     Specialty Chemicals Corporation, Ciba Specialty Chemicals PLC, Ciba
     Spezialitatenchemie Holdings Deutschland GmbH, Ciba Specialty Chemicals
     Investment Ltd., the Guarantor and the Dealers named therein (the
     "Principal Program Agreement").

(B)  The Notes will initially be represented by, and comprised in, Temporary
     Global Notes (the "Temporary Global Notes") and thereafter may be
     represented by, and comprised in, Permanent Global Notes (the "Permanent
     Global Notes" and together with the Temporary Global Notes, the "Global
     Notes"), such Global Notes representing a certain number of underlying
     Notes (the "Underlying Notes").

(C)  Each Global Note will, after issue, be deposited with a common depository
     for one or more Clearing Systems (each such Clearing System or all such
     Clearing Systems together, the "Relevant Clearing System"). Upon such
     deposit of a Global Note the Underlying Notes represented by such Global
     Note will be credited to a securities account or securities accounts with
     the Relevant Clearing System. Any account holder with the Relevant
     Clearing System which has Underlying Notes credited to its securities
     account from time to time (each a "Relevant Account Holder") will,
     subject to and in accordance with the terms and conditions and operating
     procedures or management regulations of the Relevant Clearing System, be
     entitled to transfer such Underlying Notes and (subject to and upon
     payment being made by the relevant Issuer to the bearer in accordance
     with the terms of the relevant Global Note) will be entitled to receive
     payments from the Relevant Clearing System calculated by reference to the
     Underlying Notes credited to its securities account.

(D)  In certain circumstances specified in each Global Note, a Global Note
     will become void. The time at which a Global Note becomes void is
     hereinafter referred to as the "Relevant Time". In such circumstances
     each Relevant Account Holder will, subject to and in accordance with the
     terms of this Deed, acquire against the relevant Issuer all those rights
     which such Relevant Account Holder would have had if, prior to the Global
     Note becoming void, duly executed and


<PAGE>
                                       44



     authenticated Definitive Note(s) (as defined in the Agency Agreement)
     and, if the Notes are repayable in instalments, receipts in respect
     thereof (the "Receipts") and interest coupons (the "Coupons")
     appertaining to the Definitive Note(s) (if appropriate) had been issued
     in respect of its Underlying Note(s) and such Definitive Notes(s),
     Receipts (if appropriate) and Coupons (if appropriate) were held and
     beneficially owned by such Relevant Account Holder.

(E)  The obligations of each Issuer under this Deed have been guaranteed by
     the Guarantor pursuant to the amended and restated Deed of Guarantee (the
     "Guarantee") executed by the Guarantor on 16th June, 2000 and an executed
     copy of the Guarantee has been deposited with and shall be held by The
     Chase Manhattan Bank as agent (the "Agent") for the time being for the
     Notes. A copy of the Guarantee shall be available for inspection at the
     office of the Agent for the time being (being at the date hereof at
     Trinity Tower, 9 Thomas More Street, London E1 9YT).

(F)  This Deed of Covenant amends and restates the amended and restated Deed
     of Covenant entered into by Ciba Specialty Chemicals Corporation, Ciba
     Specialty Chemicals PLC, Ciba Spezialitatenchemie Holding Deutschland
     GmbH and Ciba Specialty Chemicals Investment Ltd. dated 9th July, 1999.
     This Deed of Covenant does not affect any Notes issued pursuant to the
     Original Program Agreement prior to the date hereof.

NOW THIS DEED WITNESSES AS FOLLOWS:

1.   If any Global Note becomes void in accordance with the terms thereof the
     relevant Issuer hereby undertakes and covenants with each Relevant
     Account Holder (other than when any Relevant Clearing System is an
     account holder of any other Relevant Clearing System) that each Relevant
     Account Holder shall automatically acquire at the Relevant Time, without
     the need for any further action on behalf of any person, against the
     relevant Issuer all those rights which such Relevant Account Holder would
     have had if at the Relevant Time it held and beneficially owned duly
     executed and authenticated Definitive Note(s), Receipts (if appropriate)
     and Coupons (if appropriate) in respect of each Underlying Note
     represented by such Global Note which such Relevant Account Holder has
     credited to its securities account with the Relevant Clearing System at
     the Relevant Time. The relevant Issuer's obligation pursuant to this
     clause shall be a separate and independent obligation by reference to
     each Underlying Note which a Relevant Account Holder has credited to its
     securities account with the Relevant Clearing System and the relevant
     Issuer agrees that a Relevant Account Holder may assign its rights
     hereunder in whole or in part.

2.   The records of the Relevant Clearing System shall be conclusive evidence
     of the identity of the Relevant Account Holders and the number of
     Underlying Notes credited to the securities account of each Relevant
     Account Holder. For the purposes hereof a statement issued by the
     Relevant Clearing System stating:

     (i)  the name of the Relevant Account Holder to which such statement is
          issued; and

     (ii) the aggregate nominal amount of Underlying Notes credited to the
          securities account of such Relevant Account Holder as at the opening
          of business on the first day following the Relevant Time on which
          the Relevant Clearing System is open for business,


<PAGE>
                                       45



          shall be conclusive evidence of the records of the Relevant Clearing
          System at the Relevant Time.

3.   In the event of a dispute, the determination of the Relevant Time by the
     Relevant Clearing System shall be final and conclusive for all purposes
     in connection with the Relevant Account Holders with securities accounts
     with the Relevant Clearing System.

4.(a) Where the Issuer is Ciba Specialty Chemicals Corporation:

     The Issuer will, subject to the exceptions and limitations set forth
     below, pay as additional interest on an Underlying Note such additional
     amounts as are necessary in order that the net amounts receivable
     pursuant to the terms of the Underlying Note by each Relevant Account
     Holder who is a United States Alien (as such term is defined below),
     after deduction for any present or future tax, assessment or governmental
     charge of the United States (as such term is defined below), or a
     political subdivision or authority thereof or therein, imposed by
     withholding with respect to the payment, will not be less than the
     amounts provided for in such Underlying Note to be then due and payable;
     provided, however, that the foregoing obligation to pay additional
     amounts shall not apply to:

     (i)  any tax, assessment or governmental charge that would not have been
          so imposed but for the existence of any present or former connection
          between such Relevant Account Holder (or between a fiduciary,
          settlor, beneficiary, member or shareholder of, or holder of power
          over, such holder, if such Relevant Account Holder is an estate,
          trust, partnership or corporation) and the United States, including,
          without limitation, such Relevant Account Holder (or fiduciary,
          settlor, beneficiary, member, shareholder or holder of a power)
          being considered as:

          (A)  being or having been present or engaged in a trade or business
               in the United States or having or having had a permanent
               establishment therein;

          (B)  having a current or former relationship with the United States,
               including a relationship as a citizen or resident or being
               treated as a resident thereof;

          (C)  being or having been a personal holding company, a controlled
               foreign corporation, a passive foreign investment company, a
               foreign personal holding company with respect to the United
               States, a corporation that has accumulated earnings to avoid
               United States Federal income tax or a private foundation or
               other tax-exempt organisation; or

          (D)  an actual or a constructive "10-per cent shareholder" of the
               Issuer as defined in Section 871(h)(3) of the United States
               Internal Revenue Code of 1986, as amended (the "Code");

     (ii) any Relevant Account Holder who is a fiduciary or partnership or
          other than the sole beneficial owner of the Underlying Note, but
          only to the extent that a beneficiary or settlor with respect to
          such fiduciary or member of such partnership or a beneficial owner
          of the Underlying Note would not have been entitled to the payment
          of an additional amount had such beneficiary, settlor, member or
          beneficial owner been the Relevant Account Holder of such Underlying
          Note;


<PAGE>
                                       46



     (iii) any tax, assessment or governmental charge that would not have been
          imposed or withheld but for the failure of the Relevant Account
          Holder, if required, to comply with certification, identification or
          information reporting requirements under United States income tax
          laws, without regard to any tax treaty, with respect to the payment,
          concerning the nationality, residence, identity or connection with
          the United States of the Relevant Account Holder or a beneficial
          owner of such Underlying Note, if such compliance is required by
          United States income tax laws, without regard to any tax treaty, as
          a precondition to relief or exemption from such tax, assessment or
          governmental charge;

     (iv) any estate, inheritance, gift, sales, transfer, excise, wealth or
          personal property tax or any similar tax, assessment or governmental
          charge;

     (v)  any tax, assessment or governmental charge that is payable otherwise
          than by withholding from the payment of the amounts receivable in
          respect of such Underlying Note;

     (vi) any tax, assessment or governmental charge required to be withheld
          by any paying agent from such payment of amounts receivable in
          respect of any Underlying Note, if such payment can be made without
          such withholding by any other paying agent; or

     (vii) any combination of items (i), (ii), (iii), (iv), (v) or (vi).

     As used in this Clause, "United States" means the United States of
     America, the Commonwealth of Puerto Rico and each possession of the
     United States of America and place subject to its jurisdiction and
     "United States Alien" means any corporation, partnership, individual or
     fiduciary that, as to the United States, is for United States Federal
     income tax purposes (A) a foreign corporation, (B) a foreign partnership
     one or more of the members of which is, for United States Federal income
     tax purposes, a foreign corporation, a non-resident alien individual or a
     non-resident alien fiduciary of a foreign estate or trust, (C) a
     non-resident alien individual or (D) a non-resident alien fiduciary of a
     foreign estate or trust.

(b)  Where the Issuer is Ciba Spezialitatenchemie Holding Deutschland GmbH:

     All payments in respect of the Underlying Note by the Issuer will be made
     without withholding or deduction for or on account of any present or
     future taxes or duties of whatever nature imposed or levied by or on
     behalf of Germany or any state (Bundesland), municipality or other
     political subdivision or any authority thereof or therein having power to
     tax, unless such withholding or deduction is required by law. In such
     event, the Issuer will pay such additional amounts as shall be necessary
     in order that the net amounts received by the Relevant Account Holders
     after such withholding or deduction shall equal the amounts which would
     otherwise have been receivable in respect of the Underlying Note in the
     absence of such withholding or deduction; except that no such additional
     amounts shall be payable with respect to any Underlying Note to or to the
     order of a Relevant Account Holder who is liable for such taxes or duties
     in respect of such Underlying Note by reason of his having some
     connection with Germany other than the mere holding of such Underlying
     Note or with respect to any Underlying Note presented for payment to a
     paying agent which is required to deduct or withhold an amount for or on
     account of such taxes or duties if such amount can be paid


<PAGE>
                                       47



     without any deduction or withholding for or on account of any taxes or
     duties by any other paying agent. Any advance income tax
     (Zinsabschlagsteuer) levied in Germany since 1993 as well as the
     solidarity surcharge (Solidaritatszuschlag) imposed thereon since 1995 do
     not constitute a withholding or deduction within the meaning of this
     Clause 4(b).

(c)  Where the Issuer is Ciba Specialty Chemicals PLC:

     All payments by the Issuer in respect of the Underlying Notes shall be
     made without withholding or deduction for or on account of any present or
     future tax, duty or charge of whatever nature imposed or levied by or on
     behalf of the United Kingdom, or any authority thereof or therein having
     power to tax unless the withholding or deduction is required by law. In
     that event, the Issuer shall pay such additional amounts as will result
     (after such withholding or deduction) in the receipt by the Relevant
     Account Holders of the sums which would have been receivable (in the
     absence of such withholding or deduction) from the Issuer in respect of
     their Underlying Notes; except that no such additional amounts shall be
     payable with respect to any Underlying Note to or to the order of a
     person liable to such tax, duty or charge in respect of such Underlying
     Note by reason of his having some connection with the United Kingdom
     other than the mere holding or ownership of such Underlying Note or with
     respect to any Underlying Note presented for payment to a paying agent
     which is required to deduct or withhold an amount for or on account of
     such tax, duty or charge if such amount can be paid without any deduction
     or withholding for or on account of any tax, duty or charge by any other
     paying agent.

5.   Each Issuer hereby warrants, represents and covenants with each Relevant
     Account Holder that it has all corporate power, and has taken all
     necessary corporate or other steps, to enable it to execute, deliver and
     perform this Deed, and that this Deed constitutes a legal, valid and
     binding obligation of the relevant Issuer enforceable in accordance with
     its terms subject to the laws of bankruptcy and other laws affecting the
     rights of creditors generally.

6.   This Deed shall take effect as a Deed Poll for the benefit of the
     Relevant Account Holders from time to time and for the time being. This
     Deed shall be deposited with and held by a depository for Clearstream,
     Luxembourg and Morgan Guaranty Trust Company of New York, Brussels
     office, as operator of the Euroclear System, or any successor to the
     business thereof and for the time being (being at the date hereof The
     Chase Manhattan Bank at Trinity Tower, 9 Thomas More Street, London E1
     9YT) until all the obligations of each Issuer hereunder have been
     discharged in full.

7.   Each Issuer hereby acknowledges the right of every Relevant Account
     Holder to the production of, and the right of every Relevant Account
     Holder to obtain (upon payment of a reasonable charge) a copy of, this
     Deed, and further acknowledges and covenants that the obligations binding
     upon it contained herein are owed to, and shall be for the account of,
     each and every Relevant Account Holder, and that each Relevant Account
     Holder shall be entitled severally to enforce the said obligations
     against the relevant Issuer.

8.   This Deed is governed by, and shall be construed in accordance with, the
     laws of England.

     Each Issuer hereby irrevocably agrees, for the exclusive benefit of the
     Relevant Account Holders, that the courts of England are to have
     jurisdiction to settle any dispute which may


<PAGE>
                                       48



     arise out of, or in connection with, this Deed and that accordingly any
     suit, action or proceedings (together referred to as "Proceedings")
     arising out of, or in connection with, this Deed may be brought in such
     courts. Each Issuer irrevocably waives any objection which it may have
     now or hereafter to the laying of the venue of any Proceedings in any
     such court and any claim that any such Proceedings have been brought in
     an inconvenient forum and further irrevocably agrees that a judgment in
     any Proceedings brought in the English courts shall be conclusive and
     binding upon the relevant Issuer and may be enforced in the courts of any
     other jurisdiction (subject to the laws of the jurisdiction in which
     enforcement is sought). Nothing contained in this Clause shall limit any
     right to take Proceedings against any Issuer in any other court of
     competent jurisdiction, nor shall the taking of Proceedings in one or
     more jurisdictions preclude the taking of Proceedings in any other
     jurisdiction, whether concurrently or not (subject to the laws of the
     relevant jurisdictions). Ciba Specialty Chemicals Corporation and Ciba
     Spezialitatenchemie Holding Deutschland GmbH each hereby appoints Ciba
     Specialty Chemicals PLC at its registered office for the time being to
     accept service of process on its behalf. If Ciba Specialty Chemicals PLC
     shall cease to be registered under the laws of England and Wales, the
     relevant Issuer shall appoint another person with an office in London to
     accept such service. Nothing herein shall affect the right to serve
     process in any other manner permitted by law.

9.   This Deed may be executed by any one or more of the parties hereto in any
     number of counterparts, each of which shall be deemed to be an original,
     but all such counterparts shall together constitute one and the same
     instrument.

IN WITNESS whereof each Issuer has caused this Deed to be duly executed the
day and year first above mentioned.
