<PAGE>   6
         efforts to keep the Shelf Registration Statement effective during the
         applicable period if it voluntarily takes any action that would result
         in Worldspan not being able to sell Registrable Securities covered
         thereby during that period, unless such action is required under
         applicable law or the Company has filed a post-effective amendment to
         the Shelf Registration Statement and the SEC has not declared it
         effective.

                  2.2      Expenses.  The Company shall pay all Shelf
         Registration Expenses in connection with the registration pursuant to
         Section 2(a). Worldspan shall pay all underwriting discounts and
         commissions, the fees and disbursements of counsel representing
         Worldspan, and transfer taxes, if any, relating to the sale or
         disposition of such Registrable Securities pursuant to the Shelf
         Registration Statement.

                  2.3      Inability to File or Maintain Shelf Registration
         Statement.  The Company shall be obligated to comply with the provision
         of Section 2 hereof only if the Company is permitted, under the
         Securities Act and the rules and regulations of the SEC then
         applicable, to file and maintain the Shelf Registration Statement on a
         Form S-3 registration statement, or on any other similar forms that
         permit the registration of the Shelf Registration Securities and the
         incorporation by reference of subsequently filed documents under the
         Exchange Act. In the event that the Company is unable to comply with
         the provisions of Section 2 hereof in accordance with the foregoing
         sentence, the Company shall become obligated to provide Worldspan with
         those demand rights provided for in Section 5 hereof.

         3.       SHELF REGISTRATION PROCEDURES.

                  3.1      In connection with the obligations of the Company

                  supplement thereto in order to facilitate the public sale or
                  other disposition of the Registrable Securities; the Company
                  consents to the use of the Shelf Prospectus and any amendment
                  or supplement thereto by Worldspan of Registrable Securities
                  in connection with the offering and sale of the Registrable
                  Securities covered by the Shelf Prospectus or amendment or

                  jurisdictions in the United States and its territories and
                  possessions as Worldspan shall reasonably request in writing,
                  keep each such registration or qualification effective during
                  the period such Shelf Registration Statement is required to be
                  kept effective or during the period offers or sales are being
                  made by Worldspan after it has delivered a Shelf Registration
                  Notice to the Company, whichever is shorter; provided,
                  however, that in connection therewith, the Company shall not
                  be required to (i) qualify as a foreign corporation to do
                  business or to register as a broker or dealer in any such

                  Securities for offer or sale in any jurisdiction or the
                  initiation of any proceeding for such purpose, and (v) of the
                  happening of any event during the period the Shelf
                  Registration Statement is effective as a result of which (A)
                  such Shelf Registration Statement contains any untrue
                  statement of a material fact or omits to state any material
                  fact required to be stated therein or necessary to make the
                  statements therein not misleading or (B) the Shelf Prospectus
                  as then amended or supplemented contains any untrue statement
                  of a material fact or omits to state any material fact
                  necessary in order to make the statements therein, in light
                  of the circumstances under which they were made, not
                  misleading;

                           (f)      make every reasonable effort to obtain the
                  withdrawal of any order suspending the effectiveness of the
                  Shelf Registration Statement or any part thereof as promptly
                  as possible;

                           (g)      furnish to Worldspan after delivery of a
                  Shelf Registration Notice to the Company, without charge, at
                  least one conformed copy of the Shelf Registration Statement
                  and any post-effective amendment thereto (without documents
                  incorporated therein by reference or exhibits thereto, unless
                  requested);

                           (h)      cooperate with Worldspan to facilitate the
                  timely preparation and delivery of certificates representing
                  Registrable Securities to be sold and not bearing any
                  Securities Act legend; and enable certificates for such
                  Registrable Securities to be issued for such number of shares
                  as Worldspan may reasonably request at least two business
                  days prior to any sale of Registrable Securities; provided
                  that the Company receives timely notice thereof;

                           (i)      upon the occurrence of any event
                  contemplated by clause (v) of Section 3(e) hereof, use its
                  reasonable efforts promptly to prepare and file an amendment
                  or a supplement to the Shelf Prospectus or any document
                  incorporated therein by reference or prepare, file and obtain
                  effectiveness of a post-effective amendment to the Shelf
                  Registration Statement, or file any other required document,
                  in any such case to the extent necessary so that, as
                  thereafter delivered to the purchasers of the Registrable
                  Securities, such Shelf Prospectus as then amended or
                  supplemented will not contain any untrue statement of a
                  material fact or omit to state any material fact necessary in
                  order to make the statements therein, in the light of the
                  circumstances under which they are made, not misleading;





<PAGE>   9

                           (j)      make available for inspection by Worldspan
                  after it has provided a Shelf Registration Notice to the
                  Company and any counsel, accountants or other representatives
                  retained by Worldspan all financial and other records,
                  pertinent corporate documents and properties of the Company
                  and cause the officers, directors and employees of the
                  Company to supply all such records, documents or information
                  reasonably requested by Worldspan, counsel, accountants or
                  representatives in connection with the Shelf Registration
                  Statement; provided, however, that such records, documents or
                  information which the Company determines in good faith to be
                  confidential and notifies Worldspan, counsel, accountants or
                  representatives in writing that such records, documents or
                  information are confidential shall not be disclosed by
                  Worldspan, counsel, accountants or representatives unless (i)
                  such disclosure is ordered pursuant to a subpoena or other
                  order from a court of competent jurisdiction, or (ii) such
                  records, documents or information become generally available
                  to the public other than through a breach of this Agreement;

                           (k)      a reasonable time prior to the filing of
                  any Shelf Registration Statement or any amendment thereto, or
                  any Shelf Prospectus or any amendment or supplement thereto,
                  provide copies of such document (not including any documents
                  incorporated by reference therein unless requested) to
                  Worldspan after it has provided a Shelf Registration Notice
                  to the Company;

                           (l)      use its reasonable efforts to cause all
                  Registrable Securities to be listed on any securities
                  exchange or quotation system on which similar securities
                  issued by the Company are then listed;

                           (m)      provide a CUSIP number for all Registrable
                  Securities, not later than the effective date of a Shelf
                  Registration Statement; and

                           (n)      use its commercially reasonable efforts to
                  make available to its security holders, as soon as reasonably
                  practicable, an earnings statement covering at least 12
                  months which shall satisfy the provisions of Section 11(a) of
                  the Securities Act and Rule 158 thereunder or any similar
                  rule as may be adopted by the SEC.

         The Company may require Worldspan to furnish to the Company in writing
such information regarding the proposed distribution by Worldspan as the
Company may from time to time reasonably request in writing.

         In connection with and as a condition to the Company's obligations
with respect to the Shelf Registration Statement pursuant to Section 2 hereof
and this Section 3, Worldspan covenants and agrees that (i) it will not offer
or sell any Registrable Securities under the Shelf Registration Statement until
it has provided a Shelf Registration Notice pursuant to Section 3(b) and has
received copies of the Shelf Prospectus as then amended or supplemented as
contemplated by Section 3(c) and notice from the Company that the Shelf
Registration Statement and any post-effective amendments thereto have become
effective as contemplated by Section 3(e); (ii) upon receipt of any notice from
the Company contemplated by Section 3(e) (in respect of the occurrence of an
event contemplated by clause (v) of Section 3(e)), Worldspan shall not

<PAGE>   10
offer or sell any Registrable Securities pursuant to the Shelf Registration
Statement until Worldspan receives copies of the supplemented or amended Shelf
Prospectus contemplated by Section 3(i) hereof and receive notice that any
post-effective amendment has become effective, and, if so directed by the
Company, Worldspan will deliver to the Company (at the expense of the Company)
all copies in its possession, other than permanent file copies then in
Worldspan's possession, of the Shelf Prospectus as amended or supplemented at
the time of receipt of such notice; (iii) all offers and sales by Worldspan
under the Shelf Registration Statement shall be completed within sixty (60)
days after the first date on which offers or sales can be made pursuant to
clause (i) above, and upon expiration of such sixty (60) day period, Worldspan
will not offer or sell any Registrable Securities under the Shelf Registration
Statement until it has again complied with the provisions of clause (i) above;
(iv) Worldspan will comply with the provisions of Regulation M under the
Securities Act as applicable to it in connection with sales of Registrable
Securities pursuant to the Shelf Registration Statement; (v) Worldspan will
comply with the prospectus delivery requirements of the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to
the Shelf Registration Statement; and (vi) Worldspan will enter into such
written agreements as the Company shall reasonably request to ensure compliance
with clause (iv) and (v) above.

         4.       PIGGYBACK REGISTRATION.

         4.1      RIGHT TO PIGGYBACK.  If the Company at any time proposes to
         register any of its Common Stock or other securities under the
         Securities Act for sale to the public, whether for its own account or
         for the account of other shareholders or both (except with respect to
         registration statements on Form S-8 or another form not available for
         registering the Registrable Securities for sale to the public) (a
         "Piggyback Registration"), the Company will promptly (but in any event
         within 30 days) give written notice to Worldspan of its intention to
         effect such registration and will include in such registration all
         Registrable Securities with respect to which the Company has received a
         written request for inclusion within 15 days after the receipt of the
         Company's notice (a "Piggyback Registration Request"); provided,
         however, that the Company shall not be required to include Registrable
         Securities in the securities to be registered pursuant to a
         registration statement on any form which limits the amount of
         securities which may be registered by the issuer and/or selling
         security holders if, and to the extent that, such inclusion would make
         the use of such form unavailable. In the event that any Piggyback
         Registration shall be, in whole or in part, an underwritten public
         offering of Common Stock, any Piggyback Registration Request by
         Worldspan shall specify that either (i) such Registrable Securities are
         to be included in the underwriting on the same terms and conditions as
         the shares of Common Stock otherwise being sold through underwriters
         under such registration, or (ii) such Registrable Securities are to be
         sold in the open market without any underwriting, on terms and
         conditions comparable to those normally applicable to offerings of
         common stock in reasonably similar circumstances.

         4.2      PRIORITY ON PRIMARY REGISTRATIONS.  If a Piggyback
         Registration is an underwritten primary registration on behalf of the
         Company and the managing underwriters advise the Company in writing
         that in their opinion the number of shares requested to be included in
         such registration exceeds the maximum number which can be included in
         such offering without adversely affecting the marketability of the
         offering (the
<PAGE>   11
         "Maximum Number"), the Company will limit the number of shares included
         in such registration to the Maximum Number, and the shares registered
         shall be selected in the following order of priority: (i) first,
         securities the Company proposes to sell and (ii) other securities
         requested to be included in such registration.

                  4.3      Priority on Secondary Registrations.  If a Piggyback
         Registration is an underwritten secondary registration on behalf of
         holders of the Company's securities, and the managing underwriters
         advise the Company in writing that in their opinion the number of
         securities requested to be included in such registration exceeds the
         Maximum Number, the Company will include in such registration the
         shares requested to be included therein by the holders requesting such
         registration and the Registrable Securities covered by Piggyback
         Registration Requests and any other securities requested to be included
         in such registration, pro rata among the holders thereof on the basis
         of the number of shares requested to be included in such registration.

                  4.4      Expenses.  The Company shall pay all Piggyback
         Registration Expenses in connection with the registration pursuant to
         Section 4. Worldspan shall pay all underwriting discounts and selling
         commissions, fees and disbursements of its counsel and transfer taxes
         applicable to the sale of Registrable Securities.

         5.       DEMAND REGISTRATION.

                  5.1      Requests for Demand Registration.  In the event that
         the Company is not permitted to file the Shelf Registration Statement
         in accordance with the provisions of Section 2(c) hereof, Worldspan
         shall immediately become entitled to the rights of this Section 5.
         Accordingly, Worldspan, by written request delivered to the Company on
         or after the date 90 days after the Effective Date, may request
         registration under the Securities Act of all or any portion of the
         Registrable Securities held by Worldspan for sale in the manner
         specified in such request. Each initial request for a registration
         pursuant to this Section 5 shall specify the number of Registrable
         Securities requested to be registered and sold by Worldspan, the method
         of disposition to be employed and the Current Market Price of the
         Common Stock as of the date of such request. Any request for
         registration pursuant to this Section 5(a) shall be referred to herein
         as a "Demand Registration Request" and all registrations requested
         pursuant to this Section 5 are referred to herein as "Demand
         Registrations."

                  5.2      Number of Demand Registrations.  The Company shall be
         required to effect two (2) Demand Registrations pursuant to this
         Section 5, provided that the Company shall not be required to register
         any shares for a delayed or shelf offering pursuant to Rule 415 under
         the Securities Act unless the Company consents in writing.
         Notwithstanding anything to the contrary contained herein, a
         registration shall count as a Demand Registration only when a
         registration statement covering all Registrable Securities covered by
         such Demand Registration Request shall have become effective (except
         that if, after it has become effective, the offering of Registrable
         Securities pursuant to such registration statement is interfered with
         by any stop order, injunction or action of the SEC not occasioned by
         the fault of Worldspan, such registration shall be deemed not to have
         been effected unless such stop order, injunction or other order or
         request shall subsequently have been vacated or otherwise removed) and,
         if such method
<PAGE>   12
         of disposition is a firm commitment underwritten public offering, all
         such Registrable Securities shall have been sold pursuant thereto;
         provided, however, that if a registration statement filed by the
         Company pursuant to a Demand Registration Request shall be abandoned or
         withdrawn at the behest of Worldspan, then, unless Worldspan shall,
         promptly upon receipt of a request by the Company therefor supported by
         an invoice setting forth the expenses in reasonable detail, reimburse
         the Company for the Demand Registration Expenses in respect of such
         registration statement attributable to Worldspan, the Company shall be
         deemed to have effected a Demand Registration.

                  5.3      Minimum Offering Amount.  The Company shall not be
         required to register Registrable Securities pursuant to this Section 5
         unless the aggregate Current Market Price of all Registrable Securities
         covered by the Demand Registration Request shall be $500,000 or more
         (unless and to the extent Worldspan shall hold less than $1 million of
         Registrable Securities, in which case such minimum offering amount
         shall be equal to the amount of Registrable Securities so held).

                  5.4      Selection of Underwriters.  If the method of
         disposition specified by Worldspan shall be an underwritten public
         offering, the Company may designate the managing underwriter of such
         offering, subject to the approval of Worldspan, which approval shall
         not be unreasonably withheld.

                  5.5      Priority on Demand Registrations.  The Company shall
         be entitled to include in any registration statement referred to in
         this Section 5, for sale in accordance with the method of disposition
         specified by Worldspan, shares of Common Stock to be sold by the
         Company for its own account or by other shareholders of the Company for
         their account. Nonetheless, whether or not the Company desires to
         include any such additional shares in a Demand Registration, if such
         method of disposition is an underwritten public offering and the
         managing underwriters advise the Company in writing that in their
         opinion the number of securities requested to be included in such
         registration exceeds the Maximum Number, then the Company will limit
         the number of shares included in such registration to the Maximum
         Number, and the shares registered shall be selected in the following
         order of priority: (i) first, Registrable Securities covered by the
         Demand Registration Request, (ii) second, securities the Company
         proposes to sell and (iii) third, other securities requested to be
         included in such registration.

                  5.6      Exception. Anything in this Section 5 to the contrary
         notwithstanding, the Company shall not be required to file a
         registration statement in connection with a Demand Registration (i)
         within six months after the effective date of a Demand Registration or
         any registration statement of the type referred to in Section 4,
         provided that, as contemplated by Section 4, Worldspan shall have been
         afforded the opportunity to sell Registrable Securities pursuant to
         such registration statement, and all Registrable Securities requested
         to be registered shall have been so registered and, if such
         registration statement shall relate to an underwritten public offering,
         shall have been included therein to the extent requested by Worldspan
         and shall have been sold or (ii) if counsel for the Company, reasonably
         acceptable to Worldspan shall deliver an opinion to Worldspan to the
         effect that, pursuant to Rule 144 under the Securities Act or
         otherwise, Worldspan can publicly offer and sell the Registrable
         Securities as to which registration has been requested without
         registration under the Securities Act.
<PAGE>   13
                  5.7      Expenses. The Company shall pay all Demand
         Registration Expenses in connection with the registration pursuant to
         Section 5. Worldspan shall pay all underwriting discounts and selling
         commissions, fees and disbursements of its counsel, and transfer taxes
         applicable to the sale of Registrable Securities.

         6.       DEMAND REGISTRATION PROCEDURES.

                  6.1      If and whenever the Company is required by the
         provisions of Section 5 hereof to use its COMMERCIALLY reasonable
         efforts to effect the registration of any of the Registrable Securities
         under the Securities Act, the Company shall use its reasonable efforts
         to effect the registration and sale of the Registrable Securities in
         accordance with the intended method of disposition thereof and will, as
         expeditiously as possible:

                           (a)      and in any case within 60 days after
                  receiving a request for a Demand Registration, prepare and
                  file with the SEC a registration statement (the "Demand
                  Registration Statement") with respect to such Registrable
                  Securities and use its commercially reasonable efforts to
                  cause such Demand Registration Statement to become and remain
                  effective for the period of the distribution contemplated
                  thereby (determined as hereinafter provided). Notwithstanding
                  anything to the contrary contained herein, the filing of such
                  Demand Registration Statement may be delayed for a period not
                  to exceed 60 days if (i) the Company is contemplating a public
                  offering of its securities and, in the reasonable judgment of
                  the managing underwriter thereof (or the Company if such
                  offering is not underwritten) such filing would have a
                  material adverse effect on the contemplated offering, or (ii)
                  the Company is in possession of material non-public
                  information that it reasonably deems advisable not to disclose
                  in a Demand Registration Statement or is engaged in active
                  negotiations or planning for a merger or acquisition or
                  disposition transaction;

                           (b)      prior to the filing described in paragraph
                  (a) above, furnish to Worldspan copies of the Demand
                  Registration Statement and any amendments or supplements
                  thereto and any prospectus forming a part thereof, which
                  documents shall be subject to the approval of Worldspan only
                  with respect to any statement in the Demand Registration
                  Statement which relates to Worldspan;

                           (c)      notify Worldspan promptly and, if requested
                  by Worldspan, confirm in writing, (i) when the Demand
                  Registration Statement and any post-effective amendments
                  thereto have become effective, (ii) when any amendment or
                  supplement to the Demand Prospectus has been filed with the
                  SEC, (iii) of the issuance by the SEC or any state securities
                  authority of any stop order suspending the effectiveness of
                  the Demand Registration Statement or any part thereof or the
                  initiation of any proceedings for that purpose, (iv) if the
                  Company receives any notification with respect to the
                  suspension of the qualification of the Registrable Securities
                  for offer or sale in any jurisdiction or the initiation of any
                  proceeding for such purpose, and (v) of the happening of any
                  event during the period the Demand Registration Statement is
                  effective as a result of which (A) such Demand Registration
                  Statement contains any untrue statement of a material fact or
                  omits to state any material fact required to be stated therein
                  or necessary to make the
<PAGE>   14
                  statements therein not misleading or (B) the Demand Prospectus
                  as then amended or supplemented contains any untrue statement
                  of a material fact or omits to state any material fact
                  necessary in order to make the statements therein, in light of
                  the circumstances under which they were made, not misleading;

                           (d)      make every reasonable effort to obtain the
                  withdrawal of any order suspending the effectiveness of the
                  Demand Registration Statement or any part thereof as promptly
                  as possible;

                           (e)      furnish to Worldspan after delivery of a
                  Demand Registration Request to the Company, without charge, at
                  least one conformed copy of the Demand Registration Statement
                  and any post-effective amendment thereto (without documents
                  incorporated therein by reference or exhibits thereto, unless
                  requested);

                           (f)      prepare and file with the SEC amendments and
                  supplements to such Demand Registration Statement and the
                  Demand Prospectus used in connection therewith as may be
                  necessary to keep such Demand Registration Statement effective
                  for the period specified in paragraph (a) above and to comply
                  with the provisions of the Securities Act with respect to the
                  disposition of all Registrable Securities covered by such
                  Demand Registration Statement in accordance with Worldspan's
                  intended method of disposition set forth in such Demand
                  Registration Statement for such period;

                           (g)      furnish to Worldspan and to each underwriter
                  such number of copies of the Demand Registration Statement and
                  the Demand Prospectus included therein (including each
                  preliminary prospectus) and such other documents, as such
                  persons may reasonably request in order to facilitate the
                  public sale or other disposition of the Registrable Securities
                  covered by such Demand Registration Statement;

                           (h)      use its commercially reasonable efforts to
                  register or qualify the Registrable Securities covered by such
                  Demand Registration Statement under the securities or blue sky
                  laws of such jurisdictions as Worldspan or, in the case of an
                  underwritten public offering, the managing underwriter, shall
                  reasonably request;

                           (i)      provide a transfer agent and registrar,
                  which may be a single entity, for all Registrable Securities
                  not later than the effective date of the Demand Registration
                  Statement;

                           (j)      use its reasonable efforts to cause all
                  Registrable Securities to be listed on any securities exchange
                  or quotation system on which similar securities issued by the
                  Company are then listed;

                           (k)      if the offering is underwritten, to furnish,
                  at the request of Worldspan, on the date that Registrable
                  Securities are delivered to the underwriters for sale pursuant
                  to such registration; (i) an opinion dated such date of
                  counsel representing the Company for the purposes of such
                  registration, addressed to the underwriters, stating the such
                  Demand Registration Statement has become effective under the
                  Securities Act and that (A) to the best knowledge









<PAGE>   15
                  of such counsel, no stop order suspending the effectiveness
                  thereof has been issued and no proceedings for that purpose
                  have been instituted or are pending or contemplated under the
                  Securities Act, (B) the Demand Registration Statement, the
                  related Demand Prospectus, and each amendment or supplement
                  thereto, comply as to form in all material respects with the
                  requirements of the Securities Act and the applicable rules
                  and regulations of the SEC thereunder and that such counsel
                  does not believe that any such Demand Registration Statement,
                  Demand Prospectus, amendment or supplement contains a
                  misstatement of a material fact or an omission to state a
                  material fact required to be stated therein or necessary to
                  make the statements made therein, in light of the
                  circumstances under which they were made, not misleading
                  (except that such counsel need express no opinion as to
                  financial statements or financial or statistical data
                  contained therein) and (C) to such other effects as may
                  reasonably be requested by counsel for the underwriters or by
                  Worldspan or its counsel, and (ii) a letter dated such date
                  from the independent public accountants retained by the
                  Company, addressed to the underwriters, stating that they are
                  independent public accountants within the meaning of the
                  Securities Act and that, in the opinion of such accountants,
                  the financial statements of the Company included in the Demand
                  Registration Statement or the Demand Prospectus, or any
                  amendment or supplement thereto, comply as to form in all
                  material respects with the applicable accounting requirements
                  of the Securities Act,and such letter shall additionally cover
                  such other financial matters (including information as to the
                  period ending no more than five business days prior to the
                  date of such letter) with respect to the registration in
                  respect of which such letter is being given as such
                  underwriters may reasonably request; and

                           (1)     make available for inspection by Worldspan
                  after delivery of a Demand Registration Request to the Company
                  and any counsel, accountants or other representatives retained
                  by Worldspan all financial and other records, pertinent
                  corporate documents and properties of the Company and cause
                  the officers, directors and employees of the Company to supply
                  all such records, documents or information reasonably
                  requested by Worldspan, counsel, accountants or
                  representatives in connection with the Demand Registration
                  Statement; provided, however, that such records, documents or
                  information which the Company determines in good faith to be
                  confidential and notifies Worldspan, counsel, accountants or
                  representatives in writing that such records, documents or
                  information are confidential shall not be disclosed by
                  Worldspan, counsel, accountants or representatives unless (i)
                  such disclosure is ordered pursuant to a subpoena or other
                  order from a court of competent jurisdiction, or (ii) such
                  records, documents or information become generally available
                  to the public other than through a breach of this Agreement.

         For purposes of paragraphs (a) and (f) of this Section 6, the period of
distribution of Registrable Securities in a firm commitment underwritten public
offering shall be deemed to be that period during which the underwriters in such
offering require in an underwriting agreement in the form customarily used by
such underwriters for comparable transactions that the Company
<PAGE>   16

keep a registration statement effective to permit each underwriter to complete
the distribution of all securities purchased by it, and the period of
distribution of Registrable Securities in any other registration shall be
deemed to extend until the earlier of the sale of all Registrable Securities
covered thereby or nine months after the effective date thereof.

         In connection with each registration hereunder, Worldspan will furnish
to the Company in writing such information with respect to itself and the
proposed distribution by itself as shall be reasonably necessary in order to
assure compliance with federal and applicable state securities laws. Reasonable
compliance with the obligation to furnish such information shall be a condition
to the rights afforded Worldspan hereunder. In addition, Worldspan (i) will
comply with the provisions of Regulation M under the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to
the Demand Registration Statement; (ii) will comply with the prospectus
delivery requirements of the Securities Act as applicable to it in connection
with sales of Registrable Securities pursuant to the Demand Registration
Statement; and (iii) will enter into such written
agreements as the Company shall reasonably request to ensure compliance
therewith.

IN CONNECTION WITH EACH REGISTRATION PURSUANT TO SECTION 5 HEREOF COVERING AN
UNDERWRITTEN PUBLIC OFFERING, THE COMPANY AGREES TO ENTER INTO A WRITTEN
AGREEMENT WITH THE MANAGING UNDERWRITER SELECTED IN THE MANNER HEREIN PROVIDED
IN SUCH FORM AND CONTAINING SUCH PROVISIONS AS ARE CUSTOMARY IN THE SECURITIES
BUSINESS FOR SUCH AN ARRANGEMENT BETWEEN MAJOR UNDERWRITERS AND COMPANIES OF
THE COMPANY'S SIZE AND INVESTMENT STATURE; PROVIDED THAT SUCH AGREEMENT SHALL
NOT CONTAIN ANY SUCH PROVISION APPLICABLE TO THE COMPANY WHICH IS INCONSISTENT
WITH THE PROVISIONS HEREOF; PROVIDED, FURTHER THAT THE TIME AND PLACE OF THE
CLOSING UNDER SAID AGREEMENT SHALL BE AS MUTUALLY AGREED UPON BETWEEN THE
COMPANY AND SUCH MANAGING UNDERWRITER.

         7.       HOLDBACK AGREEMENTS.

                  7.1      Worldspan.  Worldspan agrees not to effect any
         public sale or distribution (including sales pursuant to Rule 144) of
         equity securities of the Company, or any securities convertible into
         or exchangeable or exercisable for such securities, during the 7 days
         prior to (provided that Worldspan receives a notice from the Company
         of the commencement of such 7-day period) and the 90-day period
         beginning on the effective date of any underwritten Demand
         Registration or any underwritten Piggyback Registration in which
         Registrable Securities are included (except as part of such
         underwritten registration), unless the underwriters managing the
         registered public offering otherwise agree.

                  7.2      Company Officers and Directors.  The Company agrees
         (i) not to effect any public sale or distribution of its equity
         securities, or any securities convertible into or exchangeable or
         exercisable for such securities, during the 7 days prior to (provided

         period) and the 90-day

<PAGE>   17


         period beginning on the effective date of any underwritten Demand
         Registration or underwritten Piggyback Registration (except as part
         of such underwritten registration or pursuant to registrations on Form
         S-8 or any successor form), unless the underwriters managing the
         registered public offering otherwise agree, and (ii) to use its best
         efforts to cause each of the Company's officers and directors who hold
         Common Stock or any securities convertible into or exercisable for
         Common Stock, to agree not to effect any public sale or distribution
         (including sales pursuant to Rule 144) of any such securities during
         such period (except as part of such underwritten registration, if
         otherwise permitted), unless the underwriters managing the registered
         public offering otherwise agree.

         8.       INDEMNIFICATION; CONTRIBUTION.

                  8.1      Indemnification by the Company.  The Company agrees
         to indemnify and hold harmless Worldspan and its partners, officers
         and directors and each Person, if any, who controls Worldspan within
         the meaning of Section 15 of the Securities Act as follows:

                           (a)      against any and all loss, liability, claim,
                  damage and expense whatsoever, as incurred, to which
                  Worldspan, or any partner, officer, director or controlling
                  Person may become subject under the Securities Act or
                  otherwise that arise out of or are based upon any untrue
                  statement or alleged untrue statement of a material fact
                  contained in a registration statement under which Registrable
                  Securities were registered or any prospectus included therein
                  (in each case, as amended or supplemented), or the omission
                  or alleged omission to state therein a material fact
                  required to be stated therein or necessary to make the
                  statements therein, in the light of the circumstances under
                  which they were made, not misleading;

                           (b)      against any and all loss, liability, claim,
                  damage and expense whatsoever, as incurred, to the extent of
                  the aggregate amount paid in settlement of any litigation, or
                  investigation or proceeding by any governmental agency or
                  body, commenced or threatened, or of any claim whatsoever
                  based upon any such untrue statement or alleged untrue
                  statement or any omission or alleged omission, if such
                  settlement is effected with the written consent of the
                  Company; and

                           (c)      subject to the limitations set forth in
                  Section 8(c), against any and all expense whatsoever, as
                  incurred (including reasonable fees and disbursements of
                  counsel), reasonably incurred in investigating, preparing or
                  defending against any litigation, or investigation or
                  proceeding by any governmental agency or body, commenced or
                  threatened, in each case whether or not a party, or any claim
                  whatsoever based upon any such untrue statement or alleged
                  untrue statement or omission or alleged omission, to the
                  extent that any such expense is not paid under subparagraph
                  (i) or (ii) above;

provided, however, that the indemnity provided pursuant to this Section 8(a)
shall not apply with respect to any loss, liability, claim, damage or expense
that arises out of, is based upon or results from any untrue statement or
alleged untrue statement or omission or alleged omission made in reliance upon
and in conformity with written information furnished to the Company by
<PAGE>   18
Worldspan expressly for use in the registration statement under which
Registrable Securities were registered or any prospectus included therein (in
each case, as amended or supplemented).

                  8.2      Indemnification by Worldspan.  World span agrees to
         indemnify and hold harmless the Company, and each of its respective
         directors and officers (including each director and officer of the
         Company who signed a registration statement), and each Person, if any,
         who controls the Company within the meaning of Section 15 of the
         Securities Act, to the same extent as the indemnity contained in
         Section 8(a) hereof, but only insofar as such loss, liability, claim,
         damage or expense arises out of or is based upon any untrue statement
         or alleged untrue statement or omission or alleged omission made in a
         registration statement under which Registrable Securities were
         registered or any prospectus included therein (in each case, as amended
         or supplemented), in reliance upon and in conformity with written
         information furnished to the Company by Worldspan expressly for use
         therein. In no event, however shall the liability of Worldspan exceed
         the net proceeds received by Worldspan from any offering made in
         connection with a registration statement.

                   8.3     Conduct of Indemnification Proceedings. Each
         indemnified party shall give reasonably prompt notice to each
         indemnifying party of any action or proceeding commenced against it in
         respect of which indemnity may be sought hereunder, but failure to so
         notify an indemnifying party (i) shall not relieve it from any
         liability which it may have under the indemnity agreement provided in
         Section 8(a) or (b) above, unless and to the extent it did not
         otherwise learn of such action and the lack of notice by the
         indemnified party materially prejudices the indemnifying party or
         results in the forfeiture by the indemnifying party of substantial
         rights and defenses, and (ii) shall not, in any event, relieve the
         indemnifying party from any obligations to any indemnified party other
         than the indemnification obligation provided under Section 8(a) or (b)
         above. After receipt of such notice, the indemnifying party shall be
         entitled to participate in and, to the extent it shall wish, jointly
         with any other indemnifying party so notified, to assume the defense of
         such action or proceeding at such indemnifying party's own expense with
         counsel chosen by such indemnifying party and approved by the
         indemnified party, which approval shall not be unreasonably withheld;
         provided, however, that if the defendants in any such action or
         proceeding include both the indemnified party and the indemnifying
         party and the indemnified party reasonably determines, upon advice of
         counsel, that a conflict of interest exists or that there may be legal
         defenses available to it or other indemnified parties that are
         different from or in addition to those available to the indemnifying
         party, then the indemnified party shall be entitled to one separate
         counsel, the reasonable fees and expenses of which shall be paid by the
         indemnifying party. If the indemnifying party does not assume the
         defense of any such action or proceeding, after having received the
         notice referred to in the first sentence of this paragraph, the
         indemnifying party will pay the reasonable fees and expenses of counsel
         (which shall be limited to a single law firm) for the indemnified
         party. In such event, however, the indemnifying party will be liable
         for any settlement effected without the written consent of such
         indemnifying party. If the indemnifying party assumes the defense of
         any such action or proceeding in accordance with this paragraph, such
         indemnifying party shall not be liable for any fees and expenses of
         counsel for the indemnified party incurred
<PAGE>   19
         thereafter in connection with such action or proceeding, except as set
         forth in the proviso in the second sentence of this Section 8(c).

                  8.4      Contribution.  In order to provide for just and
         equitable contribution in circumstances in which the indemnity
         agreement provided for in this Section 8 is for any reason held to be
         unenforceable although applicable in accordance with its terms, the
         Company and Worldspan shall contribute to the aggregate losses,
         liabilities, claims, damages and expenses of the nature contemplated by
         such indemnity agreement incurred by the Company and Worldspan, in such
         proportion as is appropriate to reflect the relative fault of and
         benefits to the Company on the one hand and Worldspan on the other, in
         connection with the statements or omissions which resulted in such
         losses, claims, damages, liabilities or expenses, as well as any other
         relevant equitable considerations. The relative benefits to the
         indemnifying party and indemnified parties shall be determined by
         reference to, among other things, the total proceeds received by the
         indemnified party and indemnified parties in connection with the
         offering to which such losses, claims, damages, liabilities or expenses
         relate. The relative fault of the indemnifying party and indemnified
         parties shall be determined by reference to, among other things,
         whether the action in question, including any untrue or alleged untrue
         statement of a material fact or omission or alleged omission to state a
         material fact, has been made by, or related to information supplied by,
         such indemnifying party or the indemnified parties, and the parties'
         relative intent, knowledge, access to information and opportunity to
         correct or prevent such action.

                  The parties hereto agree that it would not be just or
         equitable if contribution pursuant to this Section 8(d) were determined
         by pro rata allocation or by any other method of allocation which does
         not take account of the equitable considerations referred to in the
         immediately preceding paragraph. Notwithstanding the provisions of this
         Section 8(d), Worldspan shall not be required to contribute any amount
         in excess of the amount by which the total price at which the
         Registrable Securities of Worldspan were offered to the public exceeds
         the amount of any damages which Worldspan would otherwise have been
         required to pay by reason of such untrue statement or omission.

                  Notwithstanding the foregoing, no Person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the
         Securities Act) shall be entitled to contribution from any Person who
         was not guilty of such fraudulent misrepresentation. For purposes of
         this Section 8(d), each Person, if any, who controls Worldspan within
         the meaning of Section 15 of the Securities Act and partners, directors
         and officers of Worldspan shall have the same rights to contribution as
         Worldspan, and each director of the Company, each officer of the
         Company who signed a registration statement, and each Person, if any,
         who controls the Company within the meaning of Section 15 of the
         Securities Act shall have the same rights to contribution as the
         Company.

                  9.1      Compliance.  The Company covenants that, so long as

         shall cooperate with Worldspan to facilitate the timely preparation and
         delivery of certifies representing Registrable Securities to be sold
         and not bearing any Securities Act legend, and enable certificates for
         such Registrable Securities to be for such number of shares as

         consent of the Company, which will not be unreasonably withheld, except
         that consent will not be required in the case of an assignment to an
         affiliate of Worldspan or any entity that (i) acquires all or

         provisions hereof.
