  2.3 Pre-IPO Restructuring of Share Capital

     2.3.1 Reclassification of Shares prior to IPO

     Prior to the IPO, Nestle, in its capacity as sole shareholder of Alcon,
shall reclassify the share capital of Alcon in the following steps and within
the following deadlines:

          (a) On December 20, 2001, Alcon has held an extraordinary general
     meeting (EGM) in which its current share capital of CHF 60,000,000, divided
     into 60,000 registered shares of CHF 1,000 par value each, was subdivided
     into 300,000,000 fully paid registered common shares of CHF 0.20 par value
     each.

          This share split was recorded in the commercial register of the Canton
     of Zug prior to December 31, 2001.

          (b) On or by February 25, 2002, Alcon shall hold an EGM in which the
     following resolutions shall be taken:

             (i) conversion of 69,750,000 fully paid registered common shares of
        CHF 0.20 par value each into 69,750,000 fully paid registered nonvoting
        preferred shares (Vorzugs-Partizipationsscheine) of CHF 0.20 par value
        each. The articles of association of Alcon shall hold that the non-
        voting preferred shares shall have special dividend and liquidation
        rights, the amount and scope of which shall be left to the discretion of
        the shareholders of the company;

             (ii) ordinary capital increase (ordentliche Kapitalerhohung) in
        which the Board of Directors of Alcon is authorized, within 3 months
        after the date of the resolution, to issue up to 69,750,000 fully paid
        registered common shares of CHF 0.20 par value each. For this ordinary
        capital

                                        2
<PAGE>

        increase, Nestle shall, in the deed of capital increase, formally waive
        its pre-emptive rights to subscribe for new shares pursuant to Art. 652b
        of the Swiss Federal Code of Obligations (CO) in favor of Credit Suisse
        First Boston, Zurich (CSFB ZURICH), acting on behalf of a syndicate of
        financial institutions undertaking the IPO;

             (iii) authorized capital increase (genehmigte Kapitalerhohung)
        allowing the Board of Directors to increase Alcon's share capital, no
        later than July 31, 2002, by issuing up to 6,975,000 fully paid
        registered common shares of CHF 0.20 par value each. The Board of
        Directors shall be authorized to withdraw the pre-emptive rights of
        existing shareholders if the shares are to be used in connection with
        the over-allotment option conferred on the underwriting banks, as
        further set out in Section 2.3.5;

             (iv) conditional capital increase (bedingte Kapitalerhohung) by
        which Alcon's share capital shall be increased by a maximum amount of
        CHF 6,000,000 through the issuance of a maximum of 30,000,000 fully paid
        registered common shares of CHF 0.20 par value each. Such shares will be
        issued upon exercise of option rights which employees and members of the
        Board of Directors of Alcon Group companies are granted pursuant to the
        Alcon Incentive Plan referred to in Section 2.3.6;

             (v) election of members of the Board of Directors pursuant to
        Section 3.3.1, to become effective as of the Pricing Date;

             (vi) election of the special auditors pursuant to Section 3.5.1,
        second paragraph, to become effective as of the Pricing Date.

     The resolutions passed pursuant to this Section 2.3.1(b), other than the
resolutions under subsections (v) and (vi) shall be recorded in the commercial
register of the Canton of Zug no later than March 1, 2002.

     2.3.2 Pre-IPO Special Dividend

     The EGM convened pursuant to Section 2.3.1(b) shall, in addition to the
resolutions referred to therein, resolve on a special dividend in the amount of
up to CHF 2,100,000,000, to the extent permitted under applicable Swiss law,
payable in CHF. This dividend resolution shall be passed on the basis of year
end financial statements prepared by Alcon as of December 31, 2001 and certified
by Alcon's statutory auditors.

     The dividend resolved by the EGM shall be paid from Alcon to Nestle prior
to the date of pricing of the Alcon shares sold in the IPO (the PRICING DATE).
If necessary, Alcon shall take out a short-term loan to procure the cash amount
required to pay out the special dividend.

     Nestle and Alcon shall use their best efforts to procure that the Swiss
withholding tax of 35% due on the dividend payment can be waived pursuant to the
notification procedure (Meldeverfahren) under the Swiss Federal Withholding Tax
Act.

     2.3.3 Issuance of Firm Shares

     The shares to be sold in the IPO on the Pricing Date shall be issued as
follows:

          (a) Prior to publication of the preliminary prospectus for the IPO,
     Nestle shall determine the number of shares to be issued in the IPO on the
     basis of investor demand and expectations of the estimated IPO proceeds
     (the FIRM SHARES). The number of Firm Shares shall be communicated to Alcon
     and to CSFB Zurich.

          (b) CSFB Zurich shall pay in the par value for the Firm Shares, and
     shall de-liver a subscription form to Alcon's Board of Directors, no later
     than 5:00 p.m. Central European Time 3 business days prior to the Pricing
     Date.

<PAGE>

          (c) Upon receipt of such confirmation and subscription form, the Board
     of Directors of Alcon shall immediately resolve, in a notarized deed of
     capital increase, to increase Alcon's share capital by issuing the Firm
     Shares. The capital increase shall be filed for registration with the
     commercial register of the Canton of Zug, Switzerland, no later than 2:00
     p.m. Central European Time 2 business days prior to the Pricing Date.

          (d) The capital increase by issuance of Firm Shares shall be recorded
     in the commercial register of the Canton of Zug no later than 1 business
     day prior to the Pricing Date. The newly issued shares shall be delivered
     to or to the order of CSFB Zurich, for account of the underwriters, and
     shall be recorded in the share register of Alcon accordingly.

     2.3.4 Redemption of Preferred Shares

     Immediately following the Pricing Date, Alcon shall resolve on a redemption
of non-voting preferred shares pursuant to the following principles:

          (a) Alcon shall convene an EGM to be held on or around 10:00 a.m.
     Central European Time on the business day following the Pricing Date. Such
     EGM shall resolve, on the basis of an interim balance sheet drawn up by
     Alcon and certified by Alcon's statutory auditors in a special report
     pursuant to Art. 732 para. 2 CO, to reduce Alcon's issued and outstanding
     share capital by redemption of all 69,750,000 non-voting preferred shares
     of CHF 0.20 par value each, the proceeds of which shall be paid to Nestle.

          The amount at which the redemption shall be made shall correspond to
     the net proceeds of the sale of Firm Shares then ascertained by Alcon.

          (b) Immediately following the shareholders' resolution set forth in
     the preceding paragraph, Alcon shall publish the notice to creditors
     pursuant to Art. 733 CO.

          (c) Unless otherwise agreed by the Parties, the preferred shares shall
     be redeemed, and the proceeds of the redemption shall be paid to Nestle, as
     soon as practicable following the statutory waiting period set forth in
     Art. 734 CO, but in no event later than May 31, 2002.

          (d) Pending redemption of the preferred shares, the net proceeds of
     the IPO shall remain with Alcon, and shall be invested in such manner as
     Alcon's executive officers deem appropriate. Any proceeds from such
     investment shall go to Alcon.

     2.3.5 Issuance of Option Shares

     The shares to be sold in the IPO as a result of an exercise by the
underwriters of the over-allotment option (which may be exercised once or twice)
granted pursuant to the Underwriting Documentation shall be issued as follows:

          (a) Credit Suisse First Boston Corporation, New York (CSFB NEW YORK),
     in its capacity as global coordinator for the IPO and following
     consultation with Merrill Lynch, shall inform Nestle and Alcon of its
     intention to exercise the over-allotment option, and of the number of
     shares to which the over-allotment option relates (the OPTION SHARES).

          (b) Upon exercise by CSFB New York of the over-allotment option, CSFB
     Zurich shall pay in the par value for the Option Shares, and shall deliver
     a subscription form to Alcon's Board of Directors, no later than 10:00 a.m.
     on the business day following the exercise of the over-allotment option.

          (c) Upon receipt of such confirmation and subscription form, the Board
     of Directors of Alcon shall immediately resolve, in a notarized deed of
     capital increase,

             (i) to increase Alcon's share capital out of authorized capital by
        issuing the Option Shares, and

                                        4
<PAGE>

             (ii) to make the corresponding changes to Alcon's articles of
        association,

     and shall file such capital increase for registration with the commercial
     register of the Canton of Zug, Switzerland, immediately thereafter.

          (d) The capital increase by issuance of Option Shares shall be
     recorded in the commercial register of the Canton of Zug no later than 3
     business days following exercise of the over-allotment option. The newly
     issued shares shall be delivered to CSFB Zurich, for account of the Joint
     Lead Managers, and shall be recorded in the share register of Alcon
     accordingly.

     It is understood and agreed that there will be no dividend payment made for
the financial year 2002 on the non-voting preferred shares, whether pursuant to
Section 2.3.2 or otherwise.

     2.3.6 Shares for Incentive Plan

     It is understood and agreed that out of the 30,000,000 shares of
conditional capital created pursuant to Section 2.3.1(b)(iv), a number of shares
of CHF 0.20 par value each shall be used for the roll-over of Alcon's existing
phantom stock scheme (the ROLLOVER SHARES). The Rollover Shares shall be issued
as follows:

          (a) Alcon shall make available to qualifying employees the preliminary
     prospectus for the IPO, and shall allow such employees to convert the value
     of their existing phantom stock into Rollover Shares. Such converting
     employees will receive an additional 20% of the value of such phantom stock
     in the form of non-qualified stock options (the exact parameters of
     valuation to be made by Alcon). Employees shall be requested to make their
     election with respect to conversion within ten calendar days after the date
     of publication of the preliminary prospectus;

          (b) Alcon and its subsidiaries shall determine the number of phantom
     stock being rolled over, and the value (calculated in USD) attributable to
     such phantom stock, and will communicate these numbers to Nestle no later
     than two Business Days prior to the Pricing Date;

          (c) The value (calculated in USD) attributable to such phantom stock
     being converted into Rollover Shares shall be divided by the offering price
     (in USD) determined on the Pricing Date in order to obtain the exact number
     of Rollover Shares to be issued;

          (d) Alcon shall subscribe, or designate an Alcon Group company to
     subscribe, for the Rollover Shares, such subscription to be effected no
     later than July 15, 2002;

          (e) The Board of Directors shall issue the Rollover Shares, and shall
     deliver such shares to the subscribing Alcon Group company for the account
     of the beneficial owners of Rollover Shares, on or by July 31, 2002.

  2.4 Share Certificates and Share Register

     The share register of Alcon shall be maintained at Alcon's offices until
the Pricing Date. All share certificates issued by Alcon shall be destroyed on
or by the Pricing Date.

     As from the Pricing Date, the share register of Alcon shall be maintained
by the Bank of New York, New York, U.S.A. The Parties shall enter into
appropriate arrangements with the Bank of New York allowing for a keeping of the
share register in line with U.S. market practice, to the extent Swiss statutory
law so permits. Alcon shall further authorize Bank of New York to issue share
certificates to record shareholders of Alcon from time to time in accordance
with market practice in the United States of America. Any such share
certificates shall be validly issued both under Swiss and under applicable U.S.
federal and state laws.

     the voting rights of such Business Association);

          (c) to make investments in securities of any other Business
     Associations that are listed on a national or international securities
     exchange or regulated market in the ordinary course of business, provided
     that the aggregate equity interest of the Nestle Group in such Business
     Associations does not exceed 20% of the voting rights of such Business
     Associations;

          (d) to manufacture and/or market nutritional supplements, vitamins,
     antioxidants or any other such products to be taken orally or otherwise,
     registered or not, whose first aim is to prevent or contribute to the
     treatment of vision, ear and nose diseases;

          (e) to engage in any other pharmaceutical sector not related to eye,
     ear and nose diseases or conditions;

          (f) to engage in any business (whether as a new investment or as an
     acquisition opportunity) described in the first paragraph of this Section
     7.1 where the Board of Directors of Alcon has decided not to engage in such
     business.

     Notwithstanding any provisions of this Section 7.1 to the contrary, if
Nestle or any company of the Nestle Group acquires the assets or securities of,
or merges with, any Business Association that is engaged in a Competing
Business, such acquisition or merger shall not be deemed to be in violation of
this Section 7.1 if at the time of acquisition or merger the Competing Business
represents less than 50% of the gross revenues of the acquired Business
Association (or the Business Association merged with) for such Business
Association's most recently completed fiscal year, provided, however, that
Nestle will (i) fully and promptly inform Alcon of particulars of the competing
business to be acquired, and (ii) give Alcon a right of first refusal to acquire
these products on the basis of fair value. Should Alcon fail to exercise this
right within 30 business days of being so notified, Nestle may sell such
products or business segments to a third party or retain the products or
business segments.

  7.2 Non-Interference and Non-Solicitation

     Nestle agrees that it shall not, and shall procure that the companies of
the Nestle Group will not, for the duration of two years after the Pricing Date,
without written consent of Alcon, actively solicit for employment or hiring any
employee of the Alcon Group; provided, however, that the foregoing will not
prevent Nestle or its Subsidiaries

          (a) from employing any such employee who contacts Nestle or any
     company of the Nestle Group on his or her own initiative;

                                        15
<PAGE>

          (b) from responding to an advertisement for employment published by
     any such employee without any prior encouragement from Nestle or a Nestle
     Group company; or

          (c) from publishing and hiring through general advertisements or
     solicitations not targeted to any such employee.

  7.3 Remedies

     In case of a breach by Nestle of the restrictive covenants set out in this
Section 7, Alcon shall have the right to assert, in its own name and acting on
behalf of any Alcon Group company affected by such breach, to seek any remedies
available under applicable law, including damages, specific performance and
injunctions against Nestle, in which case Section 11 shall apply.

     The provisions of Section 8 shall apply mutatis mutandis.

8 INDEMNITY

  8.1 Scope

     The Parties have, under this Agreement, promised indemnity to each other in
various instances. In all these cases the provisions of this Section 8 shall
apply unless otherwise stated herein.

     Unless otherwise agreed,

          (a) the party liable for indemnification (the INDEMNIFYING PARTY)
     shall be liable to the party benefiting from indemnification (the
     INDEMNIFIED PARTY) for any direct damages, losses and liabilities incurred,
     costs paid (including court costs and attorney's fees) and reimbursements
     made by the Indemnified Party;

          (b) the Indemnifying Party shall further be liable to the Indemnified
     Party for any indirect, incidental, consequential or punitive damages,
     provided, however, that such obligation to indemnify shall only exist to
     the extent that liability has been successfully asserted by a third party
     that is not an Affiliate of a Party against the Indemnified Party.

  8.2 Third Party Claims

          (a) If any third party shall make any claim or commence any proceeding
     against the Indemnified Party with respect to which the Indemnified Party
     intends to make any claim for indemnification against the Indemnifying
     Party, the Indemnified Party shall promptly give written notice to the
     Indemnifying Party of such third party claim or proceeding. Failure to give
     such notice shall not, however, affect the Indemnified Party's right to
     indemnification hereunder except to the extent the Indemnifying Party
     suffers a harm, prejudice or additional cost directly caused by such
     failure.

          The Indemnifying Party shall have 20 business days after receipt of
     such notice to notify the Indemnified Party that it elects to conduct and
     control the defense of such claim, proceeding or suit (the INDEMNIFICATION
     NOTICE).

          (b) If the Indemnifying Party gives the Indemnification Notice, it
     shall have the right to undertake, conduct and control the conduct and
     settlement of such claim or proceeding at its sole expense. For such
     purpose, the Indemnifying Party may appoint counsel reasonably acceptable
     to the Indemnified Party. The Indemnified Party shall cooperate with the
     Indemnifying Party in connection therewith; provided that

             (i) the Indemnifying Party shall not permit any injunction against
        or any lien, encumbrance or other charge on any asset of the Indemnified
        Party or its Group companies;

             (ii) the Indemnifying Party shall permit the Indemnified Party (and
        counsel chosen and paid by the Indemnified Party) to monitor its conduct
        or settlement and to appoint its own

                                        16
<PAGE>

        counsel for purposes of such monitoring, and the Indemnifying Party
        shall provide the Indemnified Party with all information regarding such
        claim or proceeding as the Indemnified Party may reasonably request;

             (iii) the Indemnifying Party shall not, without the prior written
        consent of the Indemnified Party, settle or compromise any claim, or
        consent to the entry of any judgment, unless such settlement or judgment
        includes an unconditional release from all liability given by the
        claimant or the plaintiff to the Indemnified Party in respect of such
        claim or judgment; and

             (iv) the Indemnifying Party shall promptly reimburse to the extent
        required under this Section 8.2 the Indemnified Party for the full
        amount of any claim or loss resulting from such claim or proceeding and
        all related expenses incurred by the Indemnified Party (other than the
        expenses for counsel mentioned in Section 8.2(b)(ii)).

          Notwithstanding the foregoing, if the Indemnified Party, in the belief
     that a claim may materially and adversely affect it other than as a result
     of money damages or other money payments, advises the Indemnifying Party
     that it has determined to make settlement of a claim, the Indemnified Party
     shall have the right to do so at its own costs and expense, without any
     requirement to contest such claim at the request of the Indemnifying Party,
     but without any right for the indemnification by the Indemnifying Party.

          (c) If the Indemnifying Party does not give the Indemnification
     Notice, the Indemnified Party shall have the right to defend or settle such
     claim or proceeding in the exercise of its exclusive discretion subject to
     the provisions of this Section 8.2, and the Indemnifying Party shall, upon
     request from the Indemnified Party, promptly pay to the Indemnified Party
     in accordance with the other terms of this Section 8.2 the amount of any
     claim or loss (including court cost and reasonable attorneys' fees)
     resulting from its liability to the third party claimant.

          In such case, the Indemnifying Party shall nevertheless be entitled to
     monitor the conduct or settlement of such claim by the Indemnified Party.
     The Indemnified Party shall provide the Indemnifying Party and its counsel
     with information reasonably requested, but all costs and expenses incurred
     in connection with such monitoring shall be borne by the Indemnifying
     Party.

          (d) So long as the Indemnifying Party is contesting any claim or
     proceeding in good faith, the Indemnified Party shall not pay or settle any
     such claim or proceeding. If the Indemnified Party pays or settles any such
     claim or proceeding, it shall lose any right to be indemnified by the
     Indemnifying Party.

  8.3 Direct Claims

     Any claim for indemnity on account of an indemnifiable loss made directly
by the Indemnified Party against the Indemnifying Party and which does not
result from a third party claim may be asserted by written notice from the
Indemnified Party to the Indemnifying Party at any time during the applicable
statute of limitations (it being expressly understood that any prompt notice
requirement under applicable statutory law is herewith waived). Such
Indemnifying Party shall have a period of 30 business days within which to
respond thereto.

  8.4 Adjustment of Indemnifiable Losses

          (a) The amount which the Indemnifying Party is required to pay to the
     Indemnified Party shall be reduced (including, without limitation,
     retroactively) by any insurance proceeds and other amounts actually
     recovered from third parties by the Indemnified Party in reduction of the
     related claim or loss.

          The Indemnified Party agrees that the Indemnifying Party shall be
     subrogated to the Indemnified Party under any insurance policy to the
     extent it has actually indemnified the Indemnified Party.

                                        17
<PAGE>

          (b) If the Indemnified Party realizes a tax benefit or detriment in
     one or more tax periods by reason of having incurred a claim or loss for
     which it receives an Indemnity Payment from the Indemnifying Party, then,
     as the case may be,

             (i) the Indemnified Party shall pay to the Indemnifying Party an
        amount equal to the tax benefit; or

             (ii) the Indemnifying Party shall pay to the Indemnified Party an
        additional amount equal to the tax detriment;

in either case taking into account any tax detriment resulting from the receipt
of such additional amounts. Any payment due under this Section 8.4(b) with
respect to a tax benefit or tax detriment realized by an Indemnified Party in a
tax period shall be due and payable within 30 days from the time the return for
such tax period is due.

  8.5 No Third Party Beneficiaries

     The indemnification provided for in this Agreement shall not inure to the
benefit of any third party or parties (other than group companies of the
Parties) and shall not relieve any insurer or other third party who would
otherwise be obligated to pay any claim or the responsibility with respect
thereto or, solely by virtue of the indemnification provisions hereof, provide
any subrogation rights with respect thereto, and each party agrees to waive such
rights against the other to the fullest extent permitted.

  8.6 Statute of Limitations

     The statute of limitations of any indemnity provided under this Agreement
shall be ten years from the date a claim for indemnification comes into
existence.

9 COSTS AND TAXES

  9.1 Costs

     Subject to the provisions set forth in Section 2.5.1, each Party shall bear
its own costs arising out of or in connection with the negotiations of this
Agreement or the consummation of the transactions contemplated by this
Agreement.

  9.2 Taxes

     9.2.1 Taxes for Transactions under this Agreement

     Nestle shall as from the closing of the offering indemnify and hold Alcon
and the Alcon Group companies harmless against any and all costs, liabilities,
losses and damages actually suffered or incurred by Alcon or any Alcon Group
companies arising out of or resulting from any Taxes due or payable by any Alcon
Group company or as a result of the consummation of the transactions
contemplated by this Agreement, provided, however, that the following taxes
shall be borne or reimbursed by Alcon:

          (a) the Swiss issuance stamp tax (Emissionsabgabe) due on the issuance
     and sale of the Firm Shares and the Option Shares, and on the issuance of
     shares used for the Alcon Incentive Plan;

          (b) any and all Swiss transfer stamp taxes (Umsatzabgabe) due on any
     secondary share sales made in, or in connection with, the IPO (but not, for
     the avoidance of doubt, any secondary share sales made in the aftermarket
     following the IPO); and

          (c) any Swiss and other transfer stamp taxes, stamp duties and other
     levies arising as a result of or in connection with the transactions
     contemplated under Section 2.2 (but not, for the avoidance of doubt, any
     income taxes, capital gains taxes or taxes on the profit of asset sales, if
     any).

                                        18
<PAGE>

     9.2.2 Futures Taxes

     All future taxes levied on Alcon or any Alcon Group company for any tax
periods ending on or after the Pricing Date shall be the sole responsibility of
Alcon. Alcon shall fully indemnify Nestle and each Nestle Group company for, and
shall hold such companies harmless against, any costs, liabilities, losses and
damages arising out of or in connection with the assertion of any claims for
Taxes against Nestle or any Nestle Group company. The provisions of Section 8
shall apply mutatis mutandis.

     The provisions of the foregoing paragraph shall not apply with respect to
any tax claims made by the Swiss Federal tax administration against Alcon for
recapture of the Swiss issuance stamp tax (Emissionsabgabe) relating to the
corporate restructuring of Alcon closed on January 15, 1999 (the 1999
RESTRUCTURING). The Swiss issuance stamp tax on said corporate restructuring was
waived subject to the condition that Nestle's shareholding in Alcon does not
fall below 66 2/3% of Alcon's voting rights on or before January 15, 2004. If,

          (a) as a result of share sales by Nestle or as a result of capital
     increases of Alcon in which Nestle does not subscribe for shares, Nestle's
     shareholding in Alcon falls below 66 2/3% of Alcon's voting rights on or by
     January 15, 2004, and

          (b) as a consequence thereof, Alcon is obligated to pay the Swiss
     issuance stamp tax relating to the 1999 Restructuring,

     Nestle shall fully indemnify Alcon for, and shall hold Alcon harmless
against, any costs, liabilities, losses and damages arising out of or in
connection with the payment of this tax. The provisions of Section 8 shall apply
mutatis mutandis.

     shall be claimed and enforced by and against Nestle and Alcon only;

<PAGE>

at any time disclose to anyone or use for their own or any other person's

     regulations;

          (c) such information is already in the public domain by reason other

refer the matter to a joint committee consisting of the Chief Executive Officer
of Alcon Labs and General Manager/Executive Vice President Pharma and Cosmetics
