     To a Purchaser:     At such Purchaser's address as provided to the Company.

               (b)  All notices, requests, demands and other communications
given or made in accordance with the provisions of this Agreement shall be in
writing, and shall be sent by airmail, return receipt requested, or by telex or
telecopy (facsimile) with confirmation of receipt, and shall be deemed to be
given or made when receipt is so confirmed.

               (c)  Any party may, by written notice (in accordance with this
Section 9.6) to the other, alter its address.

          9.7  Amendments and Waivers.  Any term of this Agreement may be
               ----------------------
amended and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the holders of
at least sixty percent (60%) of the Common Stock issued or issuable upon
conversion of the issued shares of Series C Preferred Stock; provided, however,
that no such waiver or amendment shall reduce the aforesaid proportion of Series
C Preferred Stock, the holders of which are required to consent to any waiver or
supplemental agreement, without the consent of the record holders of all of the
issued shares of Series C Preferred Stock.  Upon the effectuation of each such
waiver or amendment, the Company shall promptly give written notice thereof to
the record holders of the issued shares of Series C Preferred Stock who have not
previously consented thereto in writing.  Any amendment or waiver effected in
accordance with this paragraph shall be binding upon each holder of any
securities purchased under this Agreement at the time outstanding (including
securities into which such securities are convertible), each future holder of
all such securities, and the Company.

          9.8  Severability.  If one or more provisions of this Agreement are
               ------------
held to be unenforceable under applicable law, such provision shall be excluded
from this Agreement and the balance of the Agreement shall be interpreted as if
such provision were so excluded and shall be enforceable in accordance with its
terms.

          9.9   Aggregation of Stock. All shares of the Preferred Stock held or
                --------------------
acquired by affiliated entities or persons shall be aggregated together for the
purpose of determining the availability of any rights under this Agreement.

          9.10  Expenses. The Company and each Purchaser shall each bear its
                --------
respective expenses and legal fees incurred with respect to this Agreement and
the transactions contemplated hereby provided that the Company shall pay the
reasonable fees and expenses of one counsel to the Purchasers not to exceed
Fifteen Thousand Dollars ($15,000).

          9.11  Delays or Omissions. No delay or omission to exercise any right,
                -------------------
power or remedy accruing to the Company or to any holder of any securities
issued or to be issued hereunder shall impair any such right, power or remedy of
the Company or such holder, nor shall it be construed to be a waiver of any
breach or default under this Agreement, or an acquiescence therein, or of or in
any similar breach or default thereafter occurring; nor shall any delay or
omission to exercise any right, power or remedy or any waiver of any single
breach or default be deemed a waiver of any other right, power or remedy or
breach or default theretofore or thereafter occurring. All remedies, either
under this Agreement, or by law otherwise afforded to the Company or any holder,
shall be cumulative and not alternative.

                                ---------------


<PAGE>

     THE SECURITIES REPRESENTED BY THIS WARRANT HAVE BEEN ACQUIRED
     FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
     ACT OF 1933. SUCH SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN
     THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER
     SAID ACT. COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THIS
     WARRANT AND RESTRICTING ITS TRANSFER MAY BE OBTAINED AT NO COST
     BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS WARRANT
     TO THE SECRETARY OF THE CORPORATION.

                                WORLDRES, INC.

                              WARRANT TO PURCHASE
                           SERIES C PREFERRED STOCK

Warrant No.: (Cert No)                                  Issue Date: (Issue Date)

     WorldRes, Inc. (the "Company"), for value received, hereby certifies that
                          -------
(Holder), or its assigns ("Holder"), is entitled to purchase from the Company,
                           ------
at any time after the date hereof and on or before the Expiration Date (as
defined in Section 8), up to (No Shares) ("No Shares Spelled") shares of Series
C Preferred Stock of the Company (the "Preferred Stock"), at a purchase price of
                                       ---------------
$4.63 per share. The shares of the Company's Series C Preferred Stock for which
this Warrant is exercisable are referred to herein as the "Warrant Shares" and
                                                           --------------
the per share purchase price of such Warrant Shares is referred to herein as the
"Stock Purchase Price."  This Warrant may be exercised at any time, or from time
 --------------------
to time, after the date hereof and on or before the Expiration Date. The Stock
Purchase Price and the Warrant Shares are subject to adjustment as provided in
Section 4.  This Warrant is one of a series of warrants issued pursuant to that
certain Amended and Restated Series C Preferred Stock and Warrant Purchase
Agreement dated March 16, 1998 (the "Agreement").
                                     ---------

     This Warrant is subject to the following terms and conditions:

     1.   Exercise; Issuance of Certificates; Payment for Shares. This Warrant
          ------------------------------------------------------
is exercisable at the option of Holder, at any time or from time to time, on or
before the Expiration Date, for all or any part of the Warrant Shares (but not
for a fraction of a share), upon surrender to the Company at its principal
office at 66 Bovet, Suite 100, San Mateo, CA 94402 (or at such other location as
the Company may advise Holder in writing) of this Warrant properly endorsed with
the Form of Subscription attached hereto as Exhibit A duly completed and signed
                                            ---------
and upon payment in cash or by check (unless this Warrant is being converted
pursuant to Section 2) of the aggregate Stock Purchase Price for the number of
Warrant Shares for which this Warrant is being exercised.  The Company agrees
that the Warrant Shares purchased under this Warrant shall be and are deemed to
be issued to Holder as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been surrendered and
payment shall have been made for such shares.  Certificates for the Warrant
Shares so purchased, together with any other securities or property to which
Holder is entitled upon such exercise, shall be delivered to Holder by the
Company at the Company's expense within a reasonable time after the rights
represented by this Warrant have been so exercised.  In case of a purchase of
less than all the
<PAGE>

Warrant Shares, the Company shall cancel this Warrant and execute and deliver a
new Warrant or Warrants of like tenor for the balance of the Warrant Shares
purchasable under the Warrant surrendered upon such purchase to Holder within a
reasonable time after the date of such surrender. Each stock certificate so
delivered shall be in such denominations as may be requested by Holder and shall
be registered in the name of Holder or such other name as shall be designated by
Holder.

     2.   Conversion of Warrant.
          ---------------------

          2.1  Right to Convert.  In addition to, and without limiting, the
               ----------------
other rights of the Holder hereunder, the Holder shall have the right (the
"Conversion Right") to convert this Warrant or any part hereof into Warrant
 ----------------
Shares at any time and from time to time during the term hereof.  Upon exercise
of the Conversion Right, the Company shall deliver to the Holder, without
payment by the Holder of any Stock Purchase Price or any cash or other
consideration, that number of Warrant Shares computed using the following
formula:

          X=Y (A-B)
            -------
               A

Where:    X=   The number of Warrant Shares to be issued to the Holder
          Y=   The number of Warrant Shares purchasable pursuant to this Warrant
          A=   The Fair Market Value of one Warrant Share as of the Conversion
               Date
          B=   The Stock Purchase Price

          2.2  Method of Exercise.  The Conversion Right may be exercised by the
               ------------------
Holder by the surrender of this Warrant to the Company at its principal office
at the address indicated on the first paragraph of this Warrant, together with a
written notice specifying that the Holder intends to exercise the Conversion
Right and indicating the number of Warrant Shares to be acquired upon exercise
of the Conversion Right.  Such conversion shall be effective upon the Company's
receipt of this Warrant, together with the conversion notice, or on such later
date as is specified in the conversion notice (the "Conversion Date") and, at
                                                    ---------------
the Holder's election, may be made contingent upon the closing of the Company's
initial public offering of any securities pursuant to a registration statement
under the Securities Act of 1933, as amended (the "Securities Act").
                                                   --------------
Certificates for the Warrant Shares so acquired shall be delivered to the Holder
within a reasonable time, not exceeding fifteen (15) days after the Conversion
Date.  If applicable, the Company shall, upon surrender of this Warrant for
cancellation, deliver a new Warrant evidencing the rights of the Holder to
purchase the balance of the Warrant Shares which Holder is entitled to purchase
hereunder.

          2.3  Fair Market Value.  "Fair Market Value" of a share of Warrant
               -----------------    -----------------
Shares or Common Stock (issued upon conversion thereof) as of a particular date
means:  (a) if traded on an exchange or quoted on The Nasdaq National Market,
then the prior trading day's closing price, (b) if conversion is effective as of
the closing of the Company's initial public offering of any securities pursuant
to a registration statement under the Securities Act, the "price to public"
specified for such shares in the final prospectus for such public offering, (c)
if listed by the National Daily Quotation Service "Pink Sheets," then the
average of the most-recently reported

                                      -2-
<PAGE>

bid and ask prices and (d) otherwise, the price as determined in good faith by
the Board of Directors of the Company.

     3.   Shares to be Fully Paid; Reservation of Shares.  The Company covenants
          ----------------------------------------------
and agrees that all Warrant Shares (and shares of its Common Stock reserved for
issuance upon conversion of such Warrant Shares) which may be issued upon the
exercise or conversion of the rights represented by this Warrant will, upon
issuance, be duly authorized, validly issued, fully paid and nonassessable and
free from all preemptive rights of any shareholder and free of all taxes, liens
and charges with respect to the issue thereof.  The Company further covenants
and agrees that during the period within which the rights represented by this
Warrant may be exercised or converted, the Company will use its best efforts to
cause a sufficient number of shares of authorized but unissued capital stock
(and shares of its Common Stock for issuance on conversion of such capital
stock, if any) to be authorized when and as required to provide for the exercise
or conversion of the rights represented by this Warrant.  The Company will take
all such action as may be necessary to assure that such shares of capital stock
(and shares of Common Stock for issuance on conversion of such capital stock, if
any) may be issued as provided herein without violation of any applicable law or
regulation, or of any requirements of any domestic securities exchange upon
which the stock may be listed.  The Company will not take any action which would
result in any adjustment of the Stock Purchase Price (as described in Section 4)
if the total number of shares of capital stock issuable after such action upon
exercise or conversion of all outstanding warrants, together with all shares of
capital stock of the same class and series as such capital stock then
outstanding and all shares of capital stock of the same class and series as such
capital stock then issuable upon exercise of all options and upon the conversion
of all convertible securities then outstanding, would exceed the total number of
shares of capital stock of the same class and series as the Warrant Shares then
authorized by the Company's Articles of Incorporation.

     4.   Adjustment of Stock Purchase Price and Number of Shares.   The Stock
          -------------------------------------------------------
Purchase Price and the number of shares purchasable upon the exercise or
conversion of this Warrant shall be subject to adjustment from time to time upon
the occurrence of certain events described in this Section 4.  Upon each
adjustment of the Stock Purchase Price, Holder shall thereafter be entitled to
purchase, at the Stock Purchase Price resulting from such adjustment, the number
of shares obtained by multiplying the Stock Purchase Price in effect immediately
prior to such adjustment by the number of shares purchasable pursuant hereto
immediately prior to such adjustment, and dividing the product thereof by the
Stock Purchase Price resulting from such adjustment.

          4.1  Subdivision or Combination of Stock.  In case the Company shall
               -----------------------------------
at any time subdivide any of its outstanding shares of the same class and series
as the Warrant Shares into a greater number of shares, the Stock Purchase Price
in effect immediately prior to such subdivision shall be proportionately
reduced, and conversely, in case any outstanding shares of the same class and
series as the Warrant Shares shall be combined into a smaller number of shares,
the Stock Purchase Price in effect immediately prior to such combination shall
be proportionately increased.

                                      -3-
<PAGE>

          4.2  Dividends, Reclassification.  If at any time or from time to time
               ---------------------------
any holders of securities of the same class and series as the Warrant Shares
shall have received or become entitled to receive, without payment thereof,

               (A)  any shares of the Company's Preferred Stock, Common Stock or
any shares of stock or other securities which are at any time directly or
indirectly convertible into or exchangeable for Common Stock, or any rights or
options to subscribe for, purchase or otherwise acquire any of the foregoing by
way of dividend or other distribution;

               (B)  any cash paid or payable otherwise than as a regular
periodic cash dividend at a rate which is substantially consistent with past
practice (or, in the case of an initial dividend, at a rate which is
substantially consistent with industry practice); or

               (C)  any shares of the Company's Preferred Stock, Common Stock or
other or additional stock or other securities or property (including cash) by
way of spinoff, split-up, reclassification, combination of shares or similar
corporate rearrangement; (other than shares of the same class and series as the
Warrant Shares issued as a stock split, adjustments in respect of which shall be
covered by the terms of Section 4.1),

then and in each such case, Holder shall, upon the exercise or conversion of
this Warrant, be entitled to receive, in addition to the number of shares of
such capital stock receivable thereupon, and without payment of any additional
consideration thereof, the amount of stock and other securities and property
(including cash in the cases referred to in clauses (B) and (C) above) which
Holder would hold on the date of such exercise or conversion had he or it been
the holder of record of such capital stock as of the date on which holders of
such capital stock received or became entitled to receive such shares and/or all
other additional stock and other securities and property.

          4.3  Conversion or Redemption.  Should all of the Company's capital
               ------------------------
stock of the same class and series as the Warrant Shares be, or if outstanding
would be, at any time prior to the expiration of this Warrant or any portion
thereof, redeemed or converted into shares of the Company's Common Stock, then
this Warrant shall immediately become exercisable or convertible for that number
of shares of the Company's Common Stock equal to the number of shares of the
Common Stock that would have been received if this Warrant had been exercised in
full and the capital stock received thereupon had been simultaneously converted
immediately prior to such event, and the Stock Purchase Price shall be
immediately adjusted to equal the quotient obtained by dividing (x) the
aggregate Stock Purchase Price of the maximum number of shares of capital stock
for which this Warrant was exercisable or convertible immediately prior to such
conversion or redemption, by (y) the number of shares of Common Stock for which
this Warrant is exercisable or convertible immediately after such conversion or
redemption.

          4.4  Other Notices.  If at any time:
               -------------

          (1)  the Company shall declare any cash dividend upon its shares of
the same class and series as the Warrant Shares;

                                      -4-
<PAGE>

          (2)  the Company shall declare any dividend upon its shares of the
same class and series as the Warrant Shares payable in stock or make any special
dividend or other distribution to the holders of its shares of the same class
and series as the Warrant Shares;

          (3)  there shall be any capital reorganization or reclassification of
the capital stock of the Company, or consolidation or merger of the Company
with, or sale of all or substantially all of its assets to, another corporation;

          (4)  there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company; or

          (5)  the Company shall take or propose to take any other action,
notice of which is actually provided to or is required to be provided, pursuant
to any written agreement, to holders of its shares of the same class and series
as the Warrant Shares,

then, in any one or more of said cases, the Company shall give, by first class
mail, postage prepaid, addressed to the Holder of this Warrant at the address of
such Holder as shown of the books of the Company, (a) at least 20 days prior
written notice of the date on which the books of the Company shall close or a
record shall be taken for such dividends or distribution or for determining
rights to vote in respect of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, and (b) in
the case of any such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding-up, at least 20 days prior written
notice of the date when the same shall take place.  Any notice given in
accordance with the foregoing clause (a) shall also specify, in the case of any
such dividend or distribution, the date on which the holders of shares of the
same class and series as the Warrant Shares shall be entitled thereto.  Any
notice given in accordance with the foregoing clause (b) shall also specify the
date on which the holders of shares of the same class and series as the Warrant
Shares shall be entitled to exchange their stock for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation or winding-up, as the case may be.

     5.   Issue Tax.  The issuance of certificates for shares of the Warrant
          ---------
Shares shall be made without charge to the Holder of the Warrant for any issue
tax in respect thereof; provided, however, that the Company shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any certificate in a name other than that of the
then Holder of the Warrant being transferred.

     6.   Closing of Books. The Company will at no time close its transfer books
          ----------------
against the transfer of any Warrant or of any shares of Warrant Shares in any
manner which interferes with the timely exercise of this Warrant.

     7.   No Voting or Dividend Rights; Limitation of Liability.  Nothing
          -----------------------------------------------------
contained in this Warrant shall be construed as conferring upon Holder the right
to vote or to consent or to receive notice as a shareholder in respect of
meetings of shareholders for the election of directors of the Company or any
other matters or any rights whatsoever as a shareholder of the Company.  No
dividends or interest shall be payable or accrued in respect of this Warrant or
the interest represented hereby or the shares purchasable hereunder until, and
only to the extent that, this

                                      -5-
<PAGE>

Warrant shall have been exercised or converted. No provisions hereof, in the
absence of affirmative action by the Holder to purchase shares of capital stock,
and no mere enumeration herein of the rights or privileges of Holder, shall give
rise to any liability of such Holder for the Stock Purchase Price or as a
shareholder of the Company, whether such liability is asserted by the Company or
by its creditors.

     8.   Expiration. This Warrant shall expire upon the earlier to occur of (a)
          ----------
5:00 PM on the third anniversary of the date hereof; (b) the effective date of
any (i) acquisition of the Company by another entity by means of any transaction
or series of related transactions (including, without limitation, any
reorganization, merger or consolidation but, excluding any merger effected
exclusively for the purpose of changing the domicile of the Company); or (ii)
sale of all or substantially all of the assets of the Company; unless the
Company's shareholders of record as constituted immediately prior to such
acquisition or sale will, immediately after such acquisition or sale (by virtue
of securities issued as consideration for the Company's acquisition or sale or
otherwise) hold at least 50% of the voting power of the surviving or acquiring
entity; or (c) the Company's sale of its Common Stock in a firm commitment
underwritten public offering pursuant to a registration statement under the
Securities Act of 1933, as amended, at a public offering price of at least
$10.00 per share (appropriately adjusted for stock dividends, stock splits,
reverse stock splits, recapitalizations or similar transactions) with gross
proceeds to the Company in excess of $15,000,000 (the "Expiration Date").
                                                       ---------------

     9.   Warrants Transferable.  Subject to the provisions of the Agreement,
          ---------------------
