Dear Sirs,

Proposed partial offers for shares in Airtours plc

6.   This letter sets out the terms on which I undertake to accept
     the offer to be made by (or on behalf of) Offeror (the "Ordinary
     Offer") to acquire up to 20,000,000 ordinary shares representing
     17.34 per cent of the current issued ordinary share capital of
     Airtours plc ("Offeree"). 

7.   The Ordinary Offer and the offer by (or on behalf of) Offeror
     (the "Preference Offer") to acquire up to 8,758,612 convertible
     cumulative preference shares representing 17.34 per cent of the
     issued convertible cumulative preference share capital of
     Offeree (together with the Ordinary Offer, "the Offers") shall
     be made substantially on the terms of the attached draft press
     announcement (the "Press Announcement"), any additional terms
     and conditions as may be required to comply with the
     requirements of The City Code on Takeovers and Mergers (the
     "Code"), the London Stock Exchange and the Securities and
     Exchange Commission and any additional terms and conditions
     agreed between Offeror and Offeree. 

8.   I warrant and undertake to you that:

8.1  I am the registered holder and beneficial owner of 30,000,000
     (the "Offeree Ordinary Shares") ordinary shares of 10p each in
     the capital of Offeree ("Ordinary Shares");

8.2  I hold the Offeree Ordinary Shares free from any lien, charge
     or other encumbrance, equity or third party right of any nature;
     and

8.3  I have full power and authority to accept the Ordinary Offer in
     respect of such number of Offeree Ordinary Shares as is referred
     to in paragraph 4.

4.1  I shall (save as provided herein) irrevocably accept the
     Ordinary Offer in respect of 5,201,224 of the Offeree Ordinary
     Shares ("the Shares"). 

4.2  My acceptance in respect of the Shares shall be made by 09.00
     am (London time) on the first closing date of the Offers in
     accordance with the procedure for acceptance set out in the
     formal document containing the Offers (the "Offer Document") to
     be despatched to Shareholders. 

4.3  I undertake that Offeror will acquire the Shares pursuant to the
     Ordinary Offer free from any lien, charge, or other encumbrance,
     equity or other third party right of any nature and together
     with all rights of any nature attaching or accruing to them
     including the right to all dividends declared, made or paid
     after the date of this letter.

4.4  I shall elect to receive only Class A Common Stock of Offeror
     as consideration under the Ordinary Offer.

4.5  My obligations under paragraphs 4.1 to 4.4 (inclusive) shall not
     apply to prevent me accepting in respect of all my Offeree
     Ordinary Shares (but not some only) and shall terminate in the
     event that there is made a general offer made by a third party
     to acquire the whole of the issued ordinary share capital of
     Offeree (other than ordinary shares already held by such third
     party or persons acting in concert therewith), which is
     unanimously recommended by the directors of Offeree, on terms
     which represent (in the opinion of the Directors of Offeree) an
     improvement on the value of the consideration offered under the
     Ordinary Offer as at the date on which a firm intention to make
     such general offer is announced (a "Competing Offer").  In the
     event that I accept a Competing Offer and if the Competing Offer
     is declared wholly unconditional, I shall pay you a cash sum
     and/or transfer securities to you (as provided below) having an
     aggregate value in an amount equal to 20% of the product of (i)
     30,000,000 and (ii) the difference between the amount per
     Ordinary Share of (a) the cash and the fair market value of any
     other consideration given to the holders of the Ordinary Shares
     pursuant to the Competing Offer, as determined by the directors
     of Offeree in good faith, and (b) L4.50.  I shall pay 
     cash/transfer securities (as provided below) to you of an
     aggregate value equal to such amount the business day after I
     receive the consideration under the Competing Offer.  In respect
     thereof, you hereby agree if requested by me to accept payment
     by way of the transfer of non-cash consideration including loan
     notes (other than loan notes received by me in respect of a
     Competing Offer which becomes or is declared unconditional in
     all respects on or after April 7, 1996) of the same type to the
     extent and in the same percentage (or such lower percentage as
     I may specify) as I receive it as consideration under the
     Competing Offer provided however that I will be responsible for
     paying all costs and expenses incurred in transferring any
     securities or other non-cash consideration (including, for the
     avoidance of doubt all transfer or other taxes) to the Offeror.
     Notwithstanding the foregoing provisions, with respect to any
     non-cash consideration that I receive in respect of a Competing
     Offer which becomes or is declared unconditional in all respects
     prior to April 7, 1996, you hereby agree that I shall have no
     obligation hereunder to make any payment or transfer of non-cash
     consideration in your favour (or to determine in what manner any
     liability which I may on April 7, 1996, have to you hereunder
     is to be discharged) until April 7, 1996.  Notwithstanding my
     absolute obligation to pay cash/transfer securities (as
     aforesaid) to you of an aggregate value equal to such amount as
     aforesaid, you agree that you shall discuss with me and consider
     in good faith potential alternative structures which I may
     propose in connection with any liability which I may have to you
     in such circumstances in order to help me minimise any tax
     liability which may arise by virtue of my accepting the
     Competing Offer or otherwise by reason of the provisions of this
     paragraph 4.5. 

4.6  An offer shall not be prevented from being a Competing Offer
     within the meaning of paragraph 4.5 solely by reason of the fact
     that, when such offer is announced, the making of it is stated
     to be the subject of a precondition to the effect that the
     resolution referred to in paragraph 7.1 below is not passed.

5.   In order to secure the performance of my obligations under
     paragraph 4, I irrevocably appoint any director for the time
     being of Offeror to be my attorney in my name and on my behalf
     to execute a Form or Forms of Acceptance and/or such other
     documents and to do such other acts and things as may be
     necessary to accept (or procure the acceptance of) the Ordinary
     Offer in respect of the Shares. However:

5.1  the appointment shall not take effect until 09.00 am (London
     time) on the first closing date of the Offers and only then if
     I have failed to comply with my obligations in paragraph 4.2;
     and

5.2  such attorney shall act in accordance with paragraph 4.4 (where
     applicable).

6.   Although the terms of the Ordinary Offer will give accepting
     shareholders the right to withdraw acceptances at any time after
     the first closing date of the Offers and before the Offers
     become or are declared unconditional in all respects I shall not
     withdraw my acceptance of the Ordinary Offer in respect of the
     Shares unless a Competing Offer is announced.  

7.   Until the Ordinary Offer becomes or is declared unconditional
     in all respects, lapses or is withdrawn (or a firm intention to
     make a Competing Offer, as defined in paragraph 4.5, is
     announced):
     
7.1  I shall exercise the voting rights attached to the Offeree
     Ordinary Shares in favour of the resolution (the "Special
     Resolution") to be proposed at a general meeting of Offeree for
     the purpose of increasing the authorised share capital of
     Offeree and disapplying the provisions of section 89 of the
     Companies Act 1985 in respect of the proposed allotment to you
     by Offeree, as referred to in the Press Announcement, of
     20,000,000 new Ordinary Shares;

7.2  Subject to my duties as a director of Offeree, I shall not,
     without the prior written consent of Offeror, signed by a duly
     authorised director, requisition or join in the requisition of
     any general or class meeting of Offeree for the purpose of
     considering any resolution affecting or having an impact on the
     Offers or the proposed allotment referred to in paragraph 7.1
     other than the Special Resolution; and

7.3  Subject to my duties as a director of Offeree, I shall not take
     any action or make any statement which is or may be prejudicial
     to the success of the Offers (it being agreed that any action
     or statement which I may take or make in relation to a Competing
     Offer, or an offer or approach which the Board of Directors of
     Offeree unanimously believes could be or may become a Competing
     Offer or lead to the person making such approach (or on whose
     behalf such approach is made) making a Competing Offer, shall
     not constitute a breach of this paragraph 7.3). 

     And in particular (without limitation):

7.4  Subject to the provisions of paragraph 4.5, I shall not offer
     any Offeree Ordinary Shares to any person or accept any other
     offer in respect of all or any of the Offeree Ordinary Shares;

7.5  I shall not make any offer to acquire or acquire the whole or
     any part of the issued share capital of Offeree and I shall
     procure that no company which I control (as such term is defined
     in Section 840 of the Income and Corporation Taxes Act 1988),
     will make such an offer or acquisition; and

7.6  I shall not enter into any agreement or arrangement with any
     person, whether conditionally or otherwise, to do any of the
     acts referred to in this paragraph 7.2 to 7.5;

     Provided always that nothing in this paragraph 7 (or elsewhere
     in this letter) shall prevent me from (i) engaging in
     discussions with any person or persons in connection with a
     Competing Offer (as defined in paragraph 4.5), or any offer or
     approach which the Board unanimously believes could be or may
     become a Competing Offer or lead to the person making such
     approach (or on whose behalf such approach is made) making a
     Competing Offer or (ii) at any time after the Board unanimously
     comes to believe that any such offer, if made, would constitute
     a Competing Offer, undertaking to accept and/or recommend to
     shareholders, or recommending, any such offer or allowing any
     such undertaking to be referred to in any announcement of a
     Competing Offer.

8.   I agree to: 

8.1  the issue of the Press Announcement in the terms attached
     (including the reference to me);

8.2  details of this undertaking being set out in the Offer Document
     and in any document filed by the Offeror with the Securities and
     Exchange Commission as a result of the transactions described
     herein or my being appointed a director of the Offeror;

8.3  this undertaking being available for inspection during the offer
     period (as defined in the Code). 

9.   I shall supply you promptly on request with all information,
     including details of my interests and dealings in securities of
     Offeror and Offeree, and (to the extent that such information
     is reasonably available to me) those of any other person
     interested in the Shares, as may be required by the Code for
     inclusion in the Offer Document or as may be required by the
     securities laws and regulations of the United States of America
     for inclusion in any document filed by the Offeror with the
     Securities and Exchange Commission as a result of the
     transactions described herein or my being appointed a director
     of the Offeror.  I shall notify you promptly of any changes to
     such information but in relation to the interests and dealings
     of any person other than myself, only to the extent that such
     changes are notified to me. 

10.  In my capacity as director of Offeree, I undertake (subject to
     my duties as a director of Offeree) to use all reasonable
     endeavours to procure that: 

10.1 the Offer Document (unless posted after the announcement of
     a firm intention to make a Competing Offer, as defined in
     paragraph 4.5) is accompanied by a letter from the
     directors of Offeree to Offeree shareholders, in a form
     agreed with Offeror (such agreement not to be unreasonably
     withheld or delayed), in which the directors unanimously
     recommend shareholders to vote in favour of the Special
     Resolution to the extent that such recommendation is not
     inconsistent with their duties as directors; 

10.2      Offeree and its directors provide Offeror and its advisers
          with any reasonable assistance and information, execute any
          documents reasonably required by the Offeror and do
          anything reasonably considered to be necessary to enable
          Offeror to:

     (a)       make the Offers in accordance with the requirements of
               the London Stock Exchange, the Code and the securities
               laws and regulations of the United States of America;
               and

     (b)  despatch the Offer Document promptly.

10.3 Until the Ordinary Offer becomes or is declared
     unconditional in all respects, lapses or is withdrawn (or
     a firm intention to make a Competing Offer, as defined in
     paragraph 4.5, is made):

     (a)  that without prior consultation with the Offeror and, in so
          far as is practicable giving due consideration to its
          views, no member of the Offeree Group will enter into any
          transaction outside the ordinary course of business which
          is material in the context of the Offeree Group as a whole;
          and

     (b)  that without the prior consent of the Offeror:

          (i)  there is no amendment to the memorandum or articles of
               association of any member of the Offeree Group;

          (ii) there is no alteration to the authorised or issued
               share capital of any member of the Offeree Group
               and no options or rights granted over any such
               share capital (other than pursuant to the Special
               Resolution or in order to satisfy existing rights
               or entitlements);

          (iii)     there is no amendment (other than the coming into
                    effect of an amendment prior to the date of this
                    letter which has been disclosed to the Offeror
                    specifically for the purposes of this letter) to
                    the service agreement or other arrangements with
                    any director of Offeree; 

          (iv) no member of the Offeree Group makes any
               acquisition or disposal of assets of a material
               amount as defined in Note 2 to rule 21 of the Code
               or grants any interest over assets of a material
               amount; or 

          (v)  no special resolution is proposed at any general
               meeting of the Offeree (other than the Special
               Resolution).

11.  Offeror's agreement to make the Offers is conditional on no
     event occurring or becoming known to you before despatch of the
     Offer Document as a result of which the Panel on Takeovers and
     Mergers (the "Panel") requires or permits Offeror not to make
     the Offer.

12.  I agree that until the Ordinary Offer becomes or is declared
     unconditional in all respects, lapses or a firm intention to
     make a Competing Offer is announced and save as required by law
     or the rules of the London Stock Exchange or the Code, I shall
     neither for my own account nor on behalf of Offeree (and I shall
     not permit any person on my behalf to) (i) initiate, solicit or
     encourage, directly or indirectly, any inquiries or the making
     of any proposal or offer (including, without limitation, any
     proposal or offer to shareholders of Offeree) with respect to
     a merger, consolidation or similar transaction involving, or any
     purchase of any of the shares of, Offeree or any purchase of any
     of any assets of Offeree or any of its subsidiaries having a
     value in excess of L25 million (or the shares of entities
     holding the same) (any such proposal or offer being hereinafter
     referred to as an "Acquisition Proposal," except that
     "Acquisition Proposal" shall not include any such transaction
     among Offeree and Offeror, Offeree and its wholly owned
     subsidiaries or among Offeree's wholly owned subsidiaries) or
     (ii) engage in any negotiations concerning, or provide any
     confidential information or data to, or have any discussions
     with, any person relating to an Acquisition Proposal, or (iii)
     otherwise facilitate directly or indirectly any effort or
     attempt to make or implement an Acquisition Proposal.  I will
     immediately terminate and use all reasonable endeavours to
     procure (in so far as in my capacity as a Director of Offeree
     I am able) that Offeree terminates any existing discussions or
     negotiations with any parties conducted to-date with respect to
     any Acquisition Proposal.  I will promptly notify you if any
     such inquiries or proposals are received by me, any such
     information is requested from me, or any such negotiations or
     discussions are sought to be initiated or continued.
     Notwithstanding the foregoing, if Offeree receives a Competing
     Offer or an offer or approach which the board of directors of
     Offeree unanimously believes could be or may become a Competing
     Offer or lead to the person making such approach (or on whose
     behalf such approach is made) making a Competing Offer, I will
     promptly notify you of such offer or approach and I may engage
     in the above-mentioned, or any other, activities.

13.1 I agree that, save as provided in paragraph 13.2 and if and
     to any extent the number of Ordinary Shares in respect of
     which you do obtain acceptances pursuant to the Ordinary
     Offer (including excess applications) falls short of
     20,000,000, I will sell to you at the time when the
     Ordinary Offer becomes or is declared unconditional in all
     respects and you will purchase upon the same terms per
     ordinary share as the terms of the Ordinary Offer such
     additional number of my Offeree Ordinary Shares as is equal
     to such shortfall, save to the extent of any part of such
     shortfall which is to be satisfied by Mr T. Trickett
     pursuant to the terms of an undertaking of even date
     herewith.  In respect of any such sale of additional
     Offeree Shares, I shall receive consideration in the form
     of Class A Common Stock of Offeror on the same terms
     (including as to the date of settlement) as under the
     Ordinary Offer.

13.2 The provisions of paragraph 13.1 shall terminate upon the
     announcement of a Competing Offer and shall be of no effect
     at any time after the making of any such announcement.

14.  This undertaking will lapse if:

14.1 the Press Announcement is not released by 8.30a.m. on 22
     February, 1996;

14.2 the Offer Document is not posted to shareholders of Offeree
     within 28 days (or such longer period as the Panel may
     agree) after the date of the Press Announcement; or

14.3 the Ordinary Offer lapses or is withdrawn.

     If the undertaking lapses, I shall have no claim against Offeror
     and Offeror shall have no claim against me.
          
15.  Any date, time or period referred to in this undertaking shall
     be of the essence except to the extent to which I and Offeror
     agree in writing to vary any date, time or period, in which
     event the varied date, time or period shall be of the essence. 

16.  I have been given a realistic opportunity to consider whether
     or not I should give this undertaking and whether I should
     receive independent advice about the nature of this undertaking.

17.  I agree that damages would not be an adequate remedy for breach
     of this undertaking.

18.  I acknowledge that, in connection with the Offers, C S First
     Boston is acting for Offeror and for no-one else and agree that
     C S First Boston will not be responsible to me for providing the
     protections afforded to its customers nor for providing advice
     in relation to the Offers.

19.  This undertaking is governed by English law and we each hereby
     submit to the exclusive jurisdiction of the High Court of
     Justice in England.

20.  I acknowledge that any shares of Class A Common Stock of Offeror
     to be acquired by me pursuant to paragraph 13 hereof have not
     been and will not be registered under the Securities Act of
     1933, as amended (the "Securities Act"), and may not be offered,
     sold, resold or delivered directly or indirectly in or into the
     United States or to, or for the account or benefit of, a US
     person (as defined in Regulation 5 promulgated under the
     Securities Act) except pursuant to an available exemption from
     registration.  I also agree to be bound by the same offering
     restrictions as are applicable to shares of Class A Common Stock
     to be issued in the Ordinary Partial Offer and agree to make
     similar representations to the Offeror in respect of United
     States securities laws as if I had signed a form of acceptance
     under the Ordinary Partial Offer in respect of any Offeree
          Ordinary Shares sold by me pursuant to paragraph 13.1.
