         not misleading at the date of this Agreement and at Completion:

         7.4.1    as if they had been repeated on each such day by reference to
                  the circumstances at the time of repetition; and

         7.4.2    on the basis that a reference to the time of repetition were

                  expressed to start at the date of this Agreement shall
                  continue to be deemed to start then)

         and references in this Agreement to the Warranties shall include them
         as so repeated.

7.5      Pioneer undertakes that:

         7.5.1    it shall not, and shall cause (as far as it can) that the
                  Society shall not, at any time before Completion do (or permit
                  or suffer to subsist or be done) any act or thing which would
                  constitute a breach of any of the Warranties or which would
                  make any of the Warranties untrue or misleading at Completion;

         7.5.2    upon Pioneer becoming aware before Completion of the actual or
                  impending occurrence or non-occurrence of any matter, event or
                  circumstance (including any omission to act) which:

                  (a)      would or might reasonably be expected to cause or
                           constitute a breach of any Warranty; or

                  (b)      would or might reasonably be expected to make any of
                           the Warranties untrue or misleading at Completion; or

                  (c)      would have caused or constituted a breach of any
                           Warranty had it been known to Pioneer before exchange
                           of this Agreement,

         it will immediately give written notice of such event to Nationwide
         with sufficient details to enable Nationwide to assess accurately the
         impact of such event and (if requested by Nationwide) use its
         reasonable endeavours promptly to prevent or remedy the event.


                                                                               8

                  with their respective terms.

                  or applied for pursuant to clause 2 of the Share Subscription
                  Agreement. For the purposes of this CLAUSE 7.8.3 the

                  received or otherwise) made with the understanding or under
                  circumstances that would indicate that all or part of the

                  government officials or as a commercial bribe, influence
                  payment or kickback.

7.9      In consideration of Nationwide entering into the Share Subscription
         Agreement Pioneer hereby undertakes to Nationwide that if the Society
         fails to make the payment of US$ 20,000,000 to Nationwide pursuant to
         clause 4.6 of the Share Subscription Agreement within the time limits
         prescribed in such clause, Pioneer shall cause the Society to make a

         Nationwide.

8.       CAPITAL AND FURTHER FINANCE

8.1      The issued share capital of the Society may from time to time be
         increased by such sum as shall be agreed between the Shareholders in
         accordance with this CLAUSE 8 and CLAUSE 5.1.3.

8.2      It is the intention of the parties that the Society should be
         self-financing and neither Shareholder shall be obliged to contribute
         further funds or participate for the benefit of the Society in any
         guarantee or similar undertaking. However, the Shareholders acknowledge
         their intention to support the Society in accordance with the then
         current Business Plan and will in good faith consider providing such
         additional funds, guarantees and undertakings as may reasonably be
         required to ensure the adequate funding of the Society. Unless the
         parties agree otherwise, all capital increases of the Society shall be
         made on a pro rata basis.

9.       GUARANTEES, ETC. GIVEN BY THE SHAREHOLDERS

         Neither Shareholder (nor any member of its respective Group) shall be
         obliged to participate for the benefit of the Society in any guarantee,
         bond, indemnity or financing arrangement with any bank or financial
         institution, whether as a guarantor or in any other capacity
         whatsoever.

10.      EXERCISE OF RIGHTS AND POWERS

         Each Shareholder undertakes with the other that (so far as it is
         legally able) it will exercise all voting rights and powers, direct and
         indirect, available to it in relation to any person and to the Society
         so as to ensure the complete and punctual fulfilment, observance and
         performance of the provisions of this Agreement (and the other
         agreements referred to in this Agreement) and generally that full
         effect is given to the principles set out in this Agreement including
         (without limitation) taking all appropriate steps to enforce this
         Agreement (and any such other agreements).


                                                                              10

         the Shares, and shall cause that none of its Associates shall do (and
         whether alone or jointly with others or whether as principal, agent,
         shareholder or otherwise and whether for its own benefit or that of
         others) any of the following without the prior written consent of the

                  person whose services have been seconded to the Society by the
                  other Shareholder or any of its Associates), but without
                  prejudice to the right of such Shareholder to terminate
                  arrangements under which any of its staff are seconded to the
                  Society, provided that nothing in this CLAUSE 11.1.2 shall
                  prevent a Shareholder making a job offer to an employee who
                  responds to a job advertisement; or

         11.1.3   carry on a trade or business or use a business name or mark

         Shareholder or other members of their respective Groups from:-

         (a)      carrying on any activity carried on during the period of 12
                  months immediately preceding the date of this Agreement;

         (b)      offering any service or goods similar to those previously
                  supplied as part of the Business but subsequently discontinued

                  service or goods are offered;

         (c)      using any of its existing business names or trademarks; or

         (d)      acquiring or holding shares amounting in aggregate between the
                  Shareholder and any of its subsidiaries to less than three per
                  cent. (3%) of the capital of a company quoted or dealt in on
                  the Warsaw Stock Exchange.


                                                                              11
<PAGE>   13
12.      DIVIDEND AND DISTRIBUTION POLICY

12.1     The Shareholders shall cause that unless otherwise expressly agreed by
         each of the Shareholders in writing or in general meeting, to the
         extent permitted by Polish law, the aggregate of the full amount of the
         profits of the Society available for distribution according to the
         audited accounts for any Financial Year and the accumulated
         distributable reserves of the Society from prior Financial Years but
         less accumulated losses shall be distributed by the Society by way of
         dividend (subject to any obligation on the Society imposed by Polish
         law to create or maintain any reserve).

13.      SHARE TRANSFERS : PRE-EMPTION PROVISIONS

13.1     Except in the case of a transfer pursuant to CLAUSE 13.10, the right to
         transfer a Share shall be subject to the provisions contained in this
         CLAUSE 13.

13.2     Before transferring any Share, the Shareholder proposing to make the
         transfer (the "TRANSFEROR") shall give notice in writing (a "TRANSFER
         NOTICE") to the other Shareholders specifying the Shares (the "SALE
         SHARES") which the Transferor wishes to transfer. A Transfer Notice
         shall be irrevocable.

13.3     A Transfer Notice may include a condition (a "TOTAL TRANSFER
         CONDITION") that if all the Sale Shares are not sold to the other
         Shareholders, then none shall be so sold.

13.4     The Transfer Notice shall state, in addition to details of the Sale
         Shares:

         13.4.1   the name or names of the person or persons (such person or
                  persons being hereinafter referred to as the "PROPOSING
                  TRANSFEREE") to whom the Sale Shares are proposed to be
                  transferred and a summary of the terms and conditions on which
                  such sale is proposed to be made in the event that the Sale
                  Shares are not acquired by the other Shareholders; and

         13.4.2   the entire consideration per Share for which any such transfer
                  or transfers will be made (and, if any of the said
                  consideration is not a cash price expressed in United States
                  Dollars, an amount per share which is so expressed) and such
                  consideration shall be the "Sale Price".

13.5     The Transfer Notice shall offer the Sale Shares for sale by the
         Proposing Transferor to all the other Shareholders at the Sale Price.

13.6     Any such offer as is required to be made by the Proposing Transferor
         pursuant to CLAUSE 13.5. shall limit a time (not being less than 14
         days or more than 21 days) after such offer is made within which it
         must be accepted or, in default will lapse. Following any such offer,
         if acceptances are received in respect of an aggregate number of Shares
         in excess of that offered, the 


                                                                              12
<PAGE>   14
         number of Sale Shares shall be allocated amongst those who have
         accepted the same in proportion to the number of Shares held by each
         acceptor provided that no acceptor shall be obliged to acquire more
         Sale Shares than the number for which he has applied and so that the
         provisions of this CLAUSE 13.6. shall continue to apply mutatis
         mutandis until all Shares which any such acceptor would but for this
         proviso have acquired on the proportionate basis specified above have
         been allocated accordingly.

13.7     If a Transfer Notice shall contain a Total Transfer Condition, then any
         such offer as aforesaid shall be conditional upon such condition being
         satisfied and no acceptance of an offer of Sale Shares will become
         effective unless such condition is satisfied. Subject thereto, any such
         offer as is required to be made by the Proposing Transferor pursuant to
         this CLAUSE 13 shall be unconditional except as provided in CLAUSE 16.

13.8     If the Proposing Transferor shall, pursuant to the foregoing provisions
         of this CLAUSE 13, find other Shareholders to purchase some or (if
         CLAUSE 13.7. shall apply) all the Sale Shares, it shall as soon as
         practicable after so doing give notice in writing thereof to the
         accepting Shareholders. Every such notice shall state the name and
         address of each of the accepting Shareholders and the number of the
         Sale Shares to be purchased by him. Upon the giving by the Company of
         any such notice as aforesaid the Proposing Transferor shall be bound,
         subject to CLAUSE 16, to complete the sale of the Sale Shares at the
         Sale Price to which such notice relates in accordance with its terms.

13.9     If the Proposing Transferor shall not, prior to the expiry of the
         Prescribed Period, find other Shareholders willing to purchase some,
         or, if the relevant Transfer Notice contains a Total Transfer
         Condition, all, of the Sale Shares, it shall be at liberty (subject to
         receiving all relevant Regulatory Approvals) to transfer those of the
         Sale Shares not purchased by other Shareholders or all the Sale Shares
         (as the case may be) to the Proposing Transferee at the Sale Price and
         otherwise on terms and conditions summarised no more favourable than
         those in the Transfer Notice.

13.10    A Shareholder shall be permitted to transfer a Share without having to
         serve a Transfer Notice pursuant to CLAUSE 13.2 if the Shareholder
         proposes to transfer such Shares to any other member of its Group
         provided that in the case of a proposed transfer to a subsidiary of the
         Shareholder or to another member of its Group which is a lower tier
         subsidiary of its holding company than the Shareholder concerned, it
         obtains the prior written consent of the other Shareholders to such
         transfer, such consent not to be unreasonably withheld or delayed.

14.      PROCEDURE IN THE EVENT OF DEADLOCK

14.1     The provisions of this clause shall apply in any case where:-


                                                                              13
<PAGE>   15
         14.1.1   a substantial matter referred to in CLAUSES 4, 5, OR 6 hereof
                  of the Society has been considered by a meeting of the
                  Supervisory Board or the Shareholders General Meeting as the
                  case may be after the text of the resolution was circulated to
                  the members of the Supervisory Board referring to this clause;
                  and

         14.1.2   no resolution has been carried at such meeting of the
                  Supervisory Board or the Shareholders, as the case may be, in
                  relation to the matter by reason of a failure to achieve the
                  required majority of votes or an equality of votes for and
                  against any proposal for dealing with it.

                  Any such case is hereinafter referred to as a "DEADLOCK".

14.2     In any case of Deadlock, Nationwide may, within ten Business Days of
         such Deadlock having arisen or become apparent, prepare and circulate
         to Pioneer a memorandum referring to this clause and setting out its
         position on the matter giving rise to the Deadlock and its reasons for
         adopting such position and requesting Pioneer to issue within the next
         ten (10) Business Days an equivalent memorandum. Each such memorandum
         shall be considered by the Chairman (or his nominee) of Nationwide and
         Pioneer and Pioneer and Nationwide shall each cause that its Chairman
         (or his nominee) shall use his reasonable endeavours to resolve the
         Deadlock within a period of thirty (30) days of his receipt of the
         first such memorandum or statement being circulated (whatever the date,
         if any, of any other such memorandum). If they agree upon a resolution
         or disposition of the matter, they shall exercise the voting rights and
         other powers of control available to them in relation to the Society to
         cause that such resolution or disposition is fully and promptly carried
         into effect. No memorandum shall be issued under this clause within 12
         months of the date of this Agreement.

14.3     If a resolution or disposition of the matter giving rise to a Deadlock
         is not agreed to the satisfaction of both Nationwide and Pioneer in
         accordance with the provisions of CLAUSE 14.2 within ninety (90) days
         after the receipt by the Chairmen of the first memorandum mentioned
         therein (or such longer period as Nationwide and Pioneer may agree in
         writing) Nationwide may give a written notice (a "DEADLOCK OPTION
         NOTICE") to Pioneer of its intention to exercise an option (which
         Pioneer hereby grants to Nationwide) to require Pioneer to purchase all
         of the Shares held by Nationwide or any Associate of Nationwide on the
         terms set out in CLAUSE 16 at the Put Option Price. A Deadlock Option
         Notice shall state that it is a Deadlock Option Notice given pursuant
         to this clause of this Agreement and shall be irrevocable except with
         the consent of Pioneer. For the avoidance of doubt, the provisions in
         this CLAUSE 14 are in addition to any right which Nationwide may have
         including but not limited to selling its Shares to a third party.


                                                                              14
<PAGE>   16
14.4     In no circumstances shall either Shareholder create an artificial
         Deadlock under this clause nor shall Nationwide exercise, or seek to
         pursue, its rights under this clause when a Deadlock is or has become
         artificial. For the purposes of this provision, a Deadlock is
         artificial if caused by a Shareholder, or its appointees on the
         Supervisory Board, voting against or persisting in their opposition to
         a proposal (i) primarily or substantially with the intention of
         frustrating or delaying the proper and efficient carrying out of the
         Business or (ii) in any case where the passage or approval of the same
         is required to enable the Society to carry on the Business properly and
         efficiently and (in either case (i) or (ii)) the implementation of the
         proposal is not directly contrary to the significant business interests
         of that Shareholder nor required by its obligations under this or any
         other agreement between the parties hereto.

15.      DEFAULT EVENT OPTION

15.1     In the event that Pioneer shall commit or suffer a Default Event,
         Nationwide shall subject to CLAUSE 15.2 be entitled but not obliged to
         adopt the procedure described in this CLAUSE 15.

15.2     Nationwide may whilst the Default Event continues to subsist but in any
         event within six (6) weeks of Nationwide first becoming aware of the
         Default Event give written notice (a "DEFAULT EVENT OPTION NOTICE") to
         Pioneer of its intention to exercise an option (which Pioneer hereby
         grants to Nationwide) to require Pioneer to purchase from Nationwide
         and any Associate of Nationwide all the Shares held by Nationwide and
         each member of Nationwide Group on the terms set out in CLAUSE 16 at
         the Put Option Price.

15.3     On the service of a Default Event Option Notice, Pioneer shall be
         deemed irrevocably to have accepted such offer at the Put Option Price.

15.4     The exercise of its rights by Nationwide under this CLAUSE 15 shall be
         without prejudice to any other rights or remedies available to
         Nationwide in respect of such Default Event including, but not limited
         to its right to sell any Shares held by it or any of its Associates to
         a third party or to seek damages or specific performance or some other
         form of equitable remedy.

15.5     For the purpose of this clause a "DEFAULT EVENT" means the occurrence
         of any of the following:-

         15.5.1   that Shareholder committing a material breach of its
                  obligations under CLAUSES 3, 4, 5, 6, 11 OR 13, of this
                  Agreement and, in the case of a breach capable of remedy,
                  failing to remedy the same to the reasonable satisfaction of
                  the other Shareholder within thirty (30) Business Days of
                  being required by notice (referring to this clause and
                  specifying the breach) so to do by the other Shareholder;


                                                                              15
<PAGE>   17
         15.5.2   that Shareholder ceasing or threatening to cease wholly or
                  substantially to carry on its business, otherwise than for the
                  purpose of a reconstruction or amalgamation without insolvency
                  and on terms previously approved by the other Shareholder
                  (such approval not to be unreasonably withheld or delayed);

         15.5.3   any receiver, liquidator, assignee, trustee or sequestrator
                  taking possession of or being appointed over the whole or any
                  part of the undertaking, property or assets of that
                  Shareholder; or

         15.5.4.  the making of an order or the passing of a resolution for the
                  winding up of that Shareholder , otherwise than for the
                  purpose of a reconstruction or amalgamation without insolvency
                  on terms previously approved by Nationwide (such approval not
                  to be unreasonably withheld or delayed).

15.6     The provisions of this CLAUSE 15 shall be without prejudice to any
         rights or remedies available to Pioneer in respect of a Default Event
         suffered or committed by Nationwide including, but not limited to
         Pioneer's right to sell any Shares held by it or any of its Associates
         to a third party or to seek damages or specific performance or some
         other form of equitable remedy.

16.      SHARE TRANSFER MECHANICS

16.1     Completion of the transfer of any Shares by one Shareholder (the
         "VENDOR") together with any other relevant members of its Group to the
         other Shareholder (the "PURCHASER") pursuant to CLAUSES 13, 14 OR 15
         shall take place on the seventh Business Day after whichever is the
         later of the date such obligation arises pursuant to those clauses and
         the date of ascertainment of the Put Option Price and the date of the
         obtaining of all necessary Regulatory Approvals and other third party
         consents and the Shareholders shall use their respective reasonable
         endeavours to obtain such Regulatory Approvals and other consents as
         soon as practicable and on terms which do not impose conditions which
         are both material and to which the affected party can reasonably (or
         does not) object. Subject to the obtaining of such Regulatory Approvals
         and other consents on such terms, completion shall take place at 12
         noon at the registered office of the Vendor (or at such other place and
         time as the Shareholders shall agree) when the Vendor shall deliver to
         the Purchaser:-

         16.1.1   a duly executed agreement transferring to the Purchaser (or as
                  it may direct) the relevant Shares together with the relevant
                  share certificates therefor, such Shares to be sold by the
                  Vendor and any other relevant members of its Group free from
                  any right of pre-emption, option, lien, charge, equity or
                  other Encumbrance and to be sold together with all rights
                  attaching thereto (including 


                                                                              16
<PAGE>   18
                  dividends declared but not paid) on the date on which the sale
                  is to take place;

         16.1.2   all other documents of title relating to the relevant Shares
                  and all such waivers or consents as the Purchaser may
                  reasonably require to enable it to be registered as the
                  holders of the relevant Shares;

         16.1.3   all third party consents or approvals (insofar as these are
                  within the power of the Vendor so to obtain) in connection
                  with the transfer of the relevant Shares to the proposed
                  Purchaser;

         16.1.4   such evidence as the Purchaser may reasonably request that any
                  relevant Regulatory Approvals and other necessary third party
                  consents have been obtained and their conditions complied
                  with; and

         16.1.5   the written resignation by deed of all members of the
                  Supervisory Board appointed or deemed to have been appointed
                  by the Vendor.

16.2     Against receipt of the documents referred to in CLAUSE 16.1, the
         Purchaser shall as a further part of completion:-

         16.2.1   deliver to the Vendor such evidence as the Vendor shall
                  reasonably request that any relevant Regulatory Approvals and
                  other necessary third party consents have been obtained and
                  their conditions complied with;

         16.2.2   put to the Vendor in (unless otherwise agreed by the
                  Shareholders) cleared funds for the purchase consideration for
                  the relevant Shares; and

         16.2.3   procure the release of the Vendor (and any of its Associates)
                  from any Guarantees given to third parties in respect of the
                  Society provided that in the event that such release is not
                  available at completion of such sale, the Purchaser (and any
                  guarantor of its obligations hereunder) shall indemnify the
                  Vendor in respect of any liability whatsoever (including
                  costs) it or its Associates may have under any such
                  Guarantees.

16.3     If Nationwide exercises the put option in CLAUSES 14.3 or 15.2, the
         Shareholders shall endeavour to agree the price at which Pioneer will
         acquire all the Shares held by Nationwide and its Associates. If the
         Shareholders fail to agree such price within 30 days of the Deadlock
         Option Notice or, as the case may be, the Default Event Option Notice,
         Nationwide and Pioneer shall each separately instruct an expert in the
         valuation of companies in the financial services sector (the "EXPERTS")
         to determine the open market value (the "MARKET VALUE") of the relevant
         Shares as between a willing seller and a willing third party buyer at
         the date of the Deadlock Option Notice or Default Event Option Notice
         (as the case may be). The Experts shall act as 


                                                                              17
<PAGE>   19
         experts and not as arbitrators and their decisions shall be
         incorporated on to a certificate. The fees and expenses claimed by each
         Expert shall be bourne by the party which instructed them. The Put
         Option Price shall be the average of the Market Values determined by
         the two Experts.

17.      ASSIGNMENT

         Neither of the Shareholders shall assign or declare any trust of any
         Shares it holds from time to time or any interest therein nor assign or
         transfer or purport to assign or transfer or declare any trust of any
         of its rights or obligations under this Agreement without the prior
         written consent of the other Shareholder.

18.      PROTECTION AND USE OF NAME

18.1     For the avoidance of doubt nothing in this Agreement permits or will
         permit Pioneer or any of its Associates or the Society to use the name
         "Nationwide" or any derivative thereof in any business conducted by
         Pioneer or any Associate of Pioneer.

18.2     For the avoidance of doubt, nothing in this Agreement permits or will
         permit Nationwide or any of its Associates to use the name "Pioneer" or
         any derivative thereof in any business conducted by Nationwide or any
         Associate of Nationwide.

18.3     Pioneer hereby confirms that it consents to the use by the Society and
         the Fund, in connection with the Business, of the name "Pioneer" and
         the trademarks and logo of Pioneer. Pioneer shall, and shall cause that
         its Associates shall, permit the Society and the Fund to use the name
         "Pioneer" for not less than four years following Completion and
         thereafter for so long as Pioneer of any other member of the Pioneer
         Group remains a Shareholder. Upon all members of the Pioneer Group
         ceasing to be a Shareholder, (a) Pioneer may give notice to the Society
         and the Fund that they are to cease to use the name "Pioneer" and
         thereafter (b) Nationwide (and any other Shareholder at that time that
         is a party to this Agreement) shall promptly exercise all voting rights
         and powers available to it to cause the Society and the Fund to change
         their names to remove the name "Pioneer" provided, however, that if
         Pioneer and the other members of the Pioneer Group cease to be a
         Shareholder before the fourth anniversary of Completion, such
         revocation of right and change of names shall not take effect until the
         fourth anniversary of Completion, unless the Shareholders agree
         otherwise on an earlier date.

         The parties further agree that as soon as practicable and in any event
         prior to Completion, Pioneer shall cause Pioneer Investment Fund
         Company to grant a non-exclusive royalty-free licence (the "LICENCE")
         to the Society to use the trademarks and logo of Pioneer in the
         Business. The parties to this 


                                                                              18
<PAGE>   20
         Agreement agree to negotiate the terms of the Licence in good faith as
         soon as practicable and in any event prior to Completion.

         Pioneer shall not and shall cause that its Associates shall not
         terminate the Licence or any other agreement permitting the Society and
         the Fund to use in connection with the Business, the trademarks or logo
         of Pioneer during the period of four years following Completion and
         thereafter for so long as Pioneer or any member of the Pioneer Group
         remains a Shareholder. Upon all members of the Pioneer Group ceasing to
         be a Shareholder, Pioneer may give, and may cause its Associates to
         give, notice to terminate or otherwise revoke the Licence and any other
         agreement permitting the Society and the Fund to use the trademarks or
         logo of Pioneer provided, however, that if Pioneer and the other
         members of the Pioneer Group cease to be a Shareholder before the
         fourth anniversary of Completion, such termination or revocation of
         rights shall not take effect until the fourth anniversary of
         Completion, unless the Shareholders agree otherwise on an earlier date.

19.      THIS AGREEMENT NOT TO CONSTITUTE A PARTNERSHIP

         None of the provisions of this Agreement (or any of the arrangements
         contemplated by this Agreement) shall be deemed to constitute a
         partnership between the parties hereto at any time or, save as
         expressly provided herein, to constitute any party the agent of the
         other, or to have any authority to bind the others in any way except as
         expressly provided.

20.      COSTS

         All costs, legal fees and other expenses incurred in the negotiation,
         preparation and execution of this Agreement shall be borne and paid by
         the party which incurred them.

21.      CONFIDENTIAL INFORMATION

21.1     Each of the parties undertakes to the other that it shall not (and
         shall procure that none of its subsidiaries shall) disclose to any
         person (other than those persons (including that person's professional
         advisers) whose province it is to know the same on a "need-to-know"
         basis for the proper implementation of this Agreement) or use or
         exploit for any purpose whatever any of the trade secrets or

         from so acting.


                                                                              19

21.2     Each party shall (and shall cause their Associates shall) (i) cause
         that anyone coming into receipt of Confidential Information
         consistently with this clause shall be informed upon receipt that such
         information is Confidential Information and (ii) use their reasonable
         endeavours to procure that any person to whom disclosure is made under
         (i) of this clause shall comply with the provisions of this clause in

         after the expiration or sooner termination of this Agreement but shall
         cease to apply to information or knowledge which:-

         21.3.1   may properly come into the public domain through no fault of
                  or breach of this Agreement by the party so restricted; or

                  by order of any court or by any competent governmental or
                  other regulatory authority, provided that any information
                  required to be disclosed pursuant to CLAUSE 21.3.2 shall be
                  disclosed only to the extent required by such law, order
                  governmental or other authority and only after consultation
                  with the other parties;

         21.3.3   information which is independently developed by the relevant
                  party or acquired from a third party to the extent that it is
                  acquired with the right to use or exploit or disclose the
                  same;

         21.3.4   any announcement made in accordance with the terms of CLAUSE
