Dear Sirs,

Proposed partial offers for shares in Airtours plc

21. 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"). 

22. 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. 

23. I warrant and undertake to you that:

23.1     I am the registered holder and beneficial owner of 7,000,000
         (the "Offeree Ordinary Shares") ordinary shares of 10p each
         in the capital of Offeree ("Ordinary Shares");

23.2     Subject only to the terms of a deed of even date herewith
         between myself and David Crossland, I hold the Offeree
         Ordinary Shares free from any lien, charge or other
         encumbrance, equity or third party right of any nature; and

23.3     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 2,000,000 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) 7,000,000 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 (other than loan notes) 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 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;

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.  For the period
    of 40 days following the Ordinary Offer becoming or being
    declared unconditional in all respects 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 18.91892 per cent
         of such shortfall or, if less, 1,500,000 of such ordinary
         shares.  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.
