Ladies and Gentlemen:

     Preview Travel, Inc., a Delaware corporation (herein called the "Company"),
proposes to issue and sell 2,500,000 shares of its authorized but unissued
Common Stock, $0.001 par value (herein called the "Common Stock") (said
2,500,000 shares of Common Stock being herein called the "Underwritten Stock").
The Company proposes to grant to the Underwriters (as hereinafter defined) an
option to purchase up to 375,000 additional shares of Common Stock (herein
called the "Option Stock" and with the Underwritten Stock herein collectively
called the "Stock").  The Common Stock is more fully described in the
Registration Statement and the Prospectus hereinafter mentioned.

     The Company hereby confirms the agreements made with respect to the
purchase of the Stock by the several underwriters, for whom you are acting,
named in Schedule I hereto (herein collectively called the "Underwriters," which
term shall also include any underwriter purchasing Stock pursuant to Section
3(b) hereof).  You represent and warrant that you have been authorized by each
of the other Underwriters to enter into this Agreement on its behalf and to act
for it in the manner herein provided.

     1.   REGISTRATION STATEMENT.  The Company has filed with the Securities and
Exchange Commission (herein called the "Commission") a registration statement on
Form S-1 (No. 333-__________), including the related preliminary prospectus, for
the registration under the Securities Act of 1933, as amended (herein called the
"Securities Act") of the Stock.  Copies of such registration statement and of
each amendment thereto, if any, including the related preliminary prospectus
(meeting the requirements of Rule 430A of the rules and regulations of the
Commission) heretofore filed by the Company with the Commission have been
delivered to you.

     The term Registration Statement as used in this agreement shall mean such
registration statement, including all exhibits and financial statements, all
information omitted therefrom in reliance upon Rule 430A and contained in the
Prospectus referred to below, in the form in which it became effective, and any
registration statement filed pursuant to Rule 462(b) of the rules and
regulations of the Commission with respect to the Stock (herein called a "Rule
462(b) registration statement"), and, in the event of any amendment thereto
after the effective date of such registration statement (herein called the
"Effective Date"), shall also mean (from and after the effectiveness of such
amendment) such registration statement as so amended (including any Rule 462(b)
registration statement).  The

term Prospectus as used in this Agreement shall mean the prospectus relating to
the Stock first filed with the Commission pursuant to Rule 424(b) and Rule 430A
(or if no such filing is required, as included in the Registration Statement)
and, in the event of any supplement or amendment to such prospectus after the
Effective Date, shall also mean (from and after the filing with the Commission
of such supplement or the effectiveness of such amendment) such prospectus as so
supplemented or amended. The term Preliminary Prospectus as used in this
Agreement shall mean each preliminary prospectus included in such registration
statement prior to the time it becomes effective.

     The Registration Statement has been declared effective under the Securities
Act, and no post-effective amendment to the Registration Statement has been
filed as of the date of this Agreement. The Company has caused to be delivered
to you copies of each Preliminary Prospectus and has consented to the use of
such copies for the purposes permitted by the Securities Act.

     2.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

          (a)  The Company hereby represents and warrants as follows:

               (i)    Each of the Company and its subsidiaries has been duly
          incorporated and is validly existing as a corporation in good standing
          under the laws of the jurisdiction of its incorporation, has full
          corporate power and authority to own or lease its properties and
          conduct its business as described in the Registration Statement and
          the Prospectus and as being conducted, and is duly qualified as a
          foreign corporation and in good standing in all jurisdictions in which
          the character of the property owned or leased or the nature of the
          business transacted by it makes qualification necessary (except where
          the failure to be so qualified would not have a material adverse
          effect on the business, properties, financial condition or results of
          operations of the Company and its subsidiaries, taken as a whole).

               (ii)   Since the respective dates as of which information is
          given in the Registration Statement and the Prospectus, there has not
          been any materially adverse change in the business, properties,
          financial condition or results of operations of the Company and its
          subsidiaries, taken as a whole, whether or not arising from
          transactions in the ordinary course of business, other than as set
          forth in the Registration Statement and the Prospectus, and since such
          dates, except in the ordinary course of business, neither the Company
          nor any of its subsidiaries has entered into any material transaction
          not referred to in the Registration Statement and the Prospectus.

               (iii)  The Registration Statement and the Prospectus comply, and
          on the Closing Date (as hereinafter defined) and any later date on
          which Option Stock is to be purchased, the Prospectus will comply, in
          all material respects, with the provisions of the Securities Act and
          the rules and regulations of the Commission thereunder; on the
          Effective Date, the Registration Statement did not contain any untrue
          statement of a material fact and did not omit to state any material
          fact required to be stated therein or necessary in order to make the
          statements therein not misleading; and, on the Effective Date, the
          Prospectus did not and, on the Closing Date and any later date on
          which Option Stock is to be purchased, 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 were made, not misleading; provided,
          however, that none of the representations and warranties in this
          subparagraph (iii) shall apply to statements in, or omissions from,
          the Registration Statement or the Prospectus made in reliance upon and
          in conformity with information herein or otherwise furnished in
          writing to the Company by or on behalf of the Underwriters for use in
          the Registration Statement or the Prospectus.

          issuance and sale of the Stock as contemplated herein.

               (v)    The Company and each of its subsidiaries owns or possesses
          adequate licenses or other rights to use all patents, copyrights,
          trademarks, service marks, trade names, technology and know-how

          manner described in the Prospectus and, except as disclosed in the
          Prospectus, neither the Company nor any of its subsidiaries has
          received any notice of infringement or conflict with (and neither the
          Company nor any of its subsidiaries knows of any infringement or
          conflict with) asserted rights of others with respect to any patents,
          copyrights, trademarks, service marks, trade names, technology or
          know-how which could result in any material adverse effect upon the
          Company and its subsidiaries, taken as a whole; and, except as
          disclosed in the Prospectus, the discoveries, inventions, products or
          processes of the Company and its subsidiaries referred to in the
          Prospectus do not, to the best knowledge of the Company or any of its
          subsidiaries, infringe or conflict with any right or patent of any
          third party, or any discovery, invention, product or process which is
          the subject of a patent application filed by any third party, known to
          the Company or any of its subsidiaries which could have a material
          adverse effect on the Company and its subsidiaries, taken as a whole.

               (vi)   No consent, approval, authorization or order of any court
          or governmental agency or body is required for the consummation of the
          transactions contemplated herein, except such as have been obtained
          under the Securities Act and such as may be required under state
          securities or blue sky laws in connection with the purchase and
          distribution of the Stock by the Underwriters.

               (vii)  All outstanding shares of Common Stock, and all securities
          convertible into or exercisable or exchangeable for Common Stock, are
          subject to valid, binding and enforceable agreements (collectively,
          the "Lock-up Agreements") that restrict the holders thereof from
          selling, making any short sale of, granting any option for the
          purchase of, or otherwise transferring or disposing of, any of such
          shares of Common Stock, or any such securities convertible into or
          exercisable or exchangeable for Common Stock, for a period of 180 days
          after the date of the Prospectus without the prior written consent of
          the Company or Hambrecht & Quist LLC Incorporated.

               (viii) The Company (i) has notified each holder of a currently
          outstanding option issued under the [name of Company option plan(s)] (
          the "Option Plan") and each person who has acquired shares of Common
          Stock pursuant to the exercise of any option granted under the Option
          Plan that pursuant to the terms of the Option Plan, none of such
          options or shares may be sold or otherwise transferred or disposed of
          for a period of 180 days after the date of the initial public offering
          of the Shares and (ii) has imposed a stop-transfer instruction with
          the Company's transfer agent in order to enforce the foregoing lock-up
          provision imposed pursuant to the Option Plan.

               (ix)   Prior to the Closing Date, the Stock to be issued and sold

          [ADDITIONAL REPRESENTATIONS AND WARRANTIES MAY BE REQUESTED AS
     IDENTIFIED PURSUANT TO OUR CONTINUING DUE DILIGENCE INVESTIGATION.]

     3.   PURCHASE OF THE STOCK BY THE UNDERWRITERS.

          (a)  On the basis of the representations and warranties and subject to
the terms and conditions herein set forth, the Company agrees to issue and sell
2,500,000 shares of the Underwritten Stock to the several Underwriters and each
of the Underwriters agrees to purchase from the Company the respective aggregate
number of shares of Underwritten Stock set forth opposite its name in Schedule
I.  The price at which such shares of Underwritten Stock shall be sold by the
Company and purchased by the several Underwriters shall be $_____ per share.  In
making this Agreement, each Underwriter is contracting severally and not
jointly; except as provided in paragraphs (b) and (c) of this Section 3, the
agreement of each Underwriter is to purchase only the respective number of
shares of the Underwritten Stock specified in Schedule I.

          (b)  If for any reason one or more of the Underwriters shall fail or
refuse (otherwise than for a reason sufficient to justify the termination of
this Agreement under the provisions of Sections 8 or 9 hereof) to purchase and
pay for the number of shares of the Stock agreed to be purchased by such
Underwriter or Underwriters, the Company shall immediately give notice thereof
to you, and the non-defaulting Underwriters shall have the right within 24 hours
after the receipt by you of such notice to purchase, or procure one or more
other Underwriters to purchase, in such proportions as may be agreed upon
between you and such purchasing Underwriter or Underwriters and upon the terms
herein set forth, all or any part of the shares of the Stock which such
defaulting Underwriter or Underwriters agreed to purchase.  If the non-
defaulting Underwriters fail so to make such arrangements with respect to all
such shares and portion, the number of shares of the Stock which each non-
defaulting Underwriter is otherwise obligated to purchase under this Agreement
shall be automatically increased on a pro rata basis to absorb the remaining
shares and portion which the defaulting Underwriter or Underwriters agreed to
purchase; provided, however, that the non-defaulting Underwriters shall not be
obligated to purchase the shares and portion which the defaulting Underwriter or
Underwriters agreed to purchase if the aggregate number of such shares of the
Stock exceeds 10% of the total number of shares of the Stock which all
Underwriters agreed to purchase hereunder.  If the total number of shares of the
Stock which the defaulting Underwriter or Underwriters agreed to purchase shall
not be purchased or absorbed in accordance with the two preceding sentences, the
Company shall have the right, within 24 hours next succeeding the 24-hour period
above referred to, to make arrangements with other underwriters or purchasers
satisfactory to you for purchase of such shares and portion on the terms herein
set forth.  In any such case, either you or the Company shall have the right to
postpone the Closing Date determined as provided in Section 5 hereof for not
more than seven business days after the date originally fixed as the Closing
Date pursuant to said Section 5 in order that any necessary changes in the
Registration Statement, the Prospectus or any other documents or arrangements
may be made.  If neither the non-defaulting Underwriters nor the Company shall
make arrangements within the 24-hour periods stated above for the purchase of
all the shares of the Stock which the defaulting Underwriter or Underwriters
agreed to purchase hereunder, this Agreement shall be terminated without further
act or deed and without any liability on the part of the Company to any non-
defaulting Underwriter and without any liability on the part of any non-
defaulting Underwriter to the Company. Nothing in this paragraph (b), and no
action taken hereunder, shall relieve any defaulting Underwriter from liability
in respect of any default of such Underwriter under this Agreement.

          (c)  On the basis of the representations, warranties and covenants
herein contained, and subject to the terms and conditions herein set forth, the
Company grants an option to the several Underwriters to purchase, severally and
not jointly, up to 375,000 shares in the aggregate of the Option Stock from the
Company at the same price per share as the Underwriters shall pay for the
Underwritten Stock.  Said option may be exercised only to cover over-allotments
in the sale of the Underwritten Stock by the Underwriters and may be exercised

whole or in part at any time (but not more than once) on or before the thirtieth
day after the date of this Agreement upon written or telegraphic notice by you
to the Company setting forth the aggregate number of shares of the Option Stock
as to which the several Underwriters are exercising the option. Delivery of
certificates for the shares of Option Stock, and payment therefor, shall be made
as provided in Section 5 hereof. The number of shares of the Option Stock to be
purchased by each Underwriter shall be the same percentage of the total number
of shares of the Option Stock to be purchased by the several Underwriters as
such Underwriter is purchasing of the Underwritten Stock, as adjusted by you in
such manner as you deem advisable to avoid fractional shares.

     4.   OFFERING BY UNDERWRITERS.

          (a)  The terms of the initial public offering by the Underwriters of
the Stock to be purchased by them shall be as set forth in the Prospectus.  The
Underwriters may from time to time change the public offering price after the
closing of the initial public offering and increase or decrease the concessions
and discounts to dealers as they may determine.

          (b)  The information set forth in the last paragraph on the front
cover page and under "Underwriting" in the Registration Statement, any
Preliminary Prospectus and the Prospectus relating to the Stock filed by the
Company (insofar as such information relates to the Underwriters) constitutes
the only information furnished by the Underwriters to the Company for inclusion
in the Registration Statement, any Preliminary Prospectus, and the Prospectus,
and you on behalf of the respective Underwriters represent and warrant to the
Company that the statements made therein are correct.

     5.   DELIVERY OF AND PAYMENT FOR THE STOCK.

          (a)  Delivery of certificates for the shares of the Underwritten Stock
and the Option Stock (if the option granted by Section 3(c) hereof shall have
been exercised not later than 7:00 A.M., San Francisco time, on the date two
business days preceding the Closing Date), and payment therefor, shall be made
at the office of ______________________________, at 7:00 a.m., San Francisco
time, on the [fourth] business day after the date of this Agreement, or at such
time on such other day, not later than seven full business days after such
[fourth] business day, as shall be agreed upon in writing by the Company and
you.  The date and hour of such delivery and payment (which may be postponed as
provided in Section 3(b) hereof) are herein called the Closing Date.

          (b)  If the option granted by Section 3(c) hereof shall be exercised
after 7:00 a.m., San Francisco time, on the date two business days preceding the
Closing Date, delivery of certificates for the shares of Option Stock, and
payment therefor, shall be made at the office of ____________________________,
at 7:00 a.m., San Francisco time, on the third business day after the exercise
of such option.

          (c)  Payment for the Stock purchased from the Company shall be made to
the Company or its order by one or more certified or official bank check or
checks in same day funds.  Such payment shall be made upon delivery of
certificates for the Stock to you for the respective accounts of the several
Underwriters against receipt therefor signed by you.  Certificates for the Stock
to be delivered to you shall be registered in such name or names and shall be in
such denominations as you may request at least one business day before the
Closing Date, in the case of Underwritten Stock, and at least one business day
prior to the purchase thereof, in the case of the Option Stock. Such
certificates will be made available to the Underwriters for inspection, checking
and packaging at the offices of Lewco Securities Corporation, 2 Broadway, New
York, New York 10004 on the business day prior to the Closing Date or, in the
case of the Option Stock, by 3:00 p.m., New York time, on the business day
preceding the date of purchase.

                                                               PRELIMINARY DRAFT
                                                          SUBJECT TO NEGOTIATION


     It is understood that you, individually and not on behalf of the
Underwriters, may (but shall not be obligated to) make payment to the Company
for shares to be purchased by any Underwriter whose check shall not have been
received by you on the Closing Date or any later date on which Option Stock is
purchased for the account of such Underwriter.  Any such payment by you shall
not relieve such Underwriter from any of its obligations hereunder.

     6.   FURTHER AGREEMENTS OF THE COMPANY. The Company covenants and agrees as
follows:

          (a)  The Company will (i) prepare and timely file with the Commission
     under Rule 424(b) a Prospectus containing information previously omitted at
     the time of effectiveness of the Registration Statement in reliance on Rule
     430A and (ii) not file any amendment to the Registration Statement or
     supplement to the Prospectus of which you shall not previously have been
     advised and furnished with a copy or to which you shall have reasonably
     objected in writing or which is not in compliance with the Securities Act
     or the rules and regulations of the Commission.

          (b)  The Company will promptly notify each Underwriter in the event of
     (i) the request by the Commission for amendment of the Registration
     Statement or for supplement to the Prospectus or for any additional
     information, (ii) the issuance by the Commission of any stop order
     suspending the effectiveness of the Registration Statement, (iii) the
     institution or notice of intended institution of any action or proceeding
     for that purpose, (iv) the receipt by the Company of any notification with
     respect to the suspension of the qualification of the Stock for sale in any
     jurisdiction, or (v) the receipt by it of notice of the initiation or
     threatening of any proceeding for such purpose.  The Company will make
     every reasonable effort to prevent the issuance of such a stop order and,
     if such an order shall at any time be issued, to obtain the withdrawal
     thereof at the earliest possible moment.

          (c)  The Company will (i) on or before the Closing Date, deliver to
     you a signed copy of the Registration Statement as originally filed and of
     each amendment thereto filed prior to the time the Registration Statement
     becomes effective and, promptly upon the filing thereof, a signed copy of
     each post-effective amendment, if any, to the Registration Statement
     (together with, in each case, all exhibits thereto unless previously
     furnished to you) and will also deliver to you, for distribution to the
     Underwriters, a sufficient number of additional conformed copies of each of
     the foregoing (but without exhibits) so that one copy of each may be
     distributed to each Underwriter, (ii) as promptly as possible deliver to
     you and send to the several Underwriters, at such office or offices as you
     may designate, as many copies of the Prospectus as you may reasonably
     request, and (iii) thereafter from time to time during the period in which
     a prospectus is required by law to be delivered by an Underwriter or
     dealer, likewise send to the Underwriters as many additional copies of the
     Prospectus and as many copies of any supplement to the Prospectus and of
     any amended prospectus, filed by the Company with the Commission, as you
     may reasonably request for the purposes contemplated by the Securities Act.

          (d)  If at any time during the period in which a prospectus is
     required by law to be delivered by an Underwriter or dealer any event
     relating to or affecting the Company, or of which the Company shall be
     advised in writing by you, shall occur as a result of which it is
     necessary, in the opinion of counsel for the Company or of counsel for the
     Underwriters, to supplement or amend the Prospectus in order to make the
     Prospectus not misleading in the light of the circumstances existing at the
     time it is delivered to a purchaser of the Stock, the Company will
     forthwith prepare and file with the Commission a supplement to the
     Prospectus or an amended prospectus so that the Prospectus as so
     supplemented or amended will not contain any untrue statement of a material
     fact or omit to state any material fact necessary in order to make

                                                          SUBJECT TO NEGOTIATION


     the statements therein, in the light of the circumstances existing at the
     time such Prospectus is delivered to such purchaser, not misleading. If,
     after the initial public offering of the Stock by the Underwriters and
     during such period, the Underwriters shall propose to vary the terms of
     offering thereof by reason of changes in general market conditions or
     otherwise, you will advise the Company in writing of the proposed
     variation, and, if in the opinion either of counsel for the Company or of
     counsel for the Underwriters such proposed variation requires that the
     Prospectus be supplemented or amended, the Company will forthwith prepare
     and file with the Commission a supplement to the Prospectus or an amended
     prospectus setting forth such variation. The Company authorizes the
     Underwriters and all dealers to whom any of the Stock may be sold by the
     several Underwriters to use the Prospectus, as from time to time amended or
     supplemented, in connection with the sale of the Stock in accordance with
     the applicable provisions of the Securities Act and the applicable rules
     and regulations thereunder for such period.

          (e)  Prior to the filing thereof with the Commission, the Company will
     submit to you, for your information, a copy of any post-effective amendment
     to the Registration Statement and any supplement to the Prospectus or any
     amended prospectus proposed to be filed.

          (f)  The Company will cooperate, when and as requested by you, in the
     qualification of the Stock for offer and sale under the securities or blue
     sky laws of such jurisdictions as you may designate and, during the period
     in which a prospectus is required by law to be delivered by an Underwriter
     or dealer, in keeping such qualifications in good standing under said

     be obligated to file any general consent to service of process or to
     qualify as a foreign corporation in any jurisdiction in which it is not so
     qualified.  The Company will, from time to time, prepare and file such
     statements, reports, and other documents as are or may be required to
     continue such qualifications in effect for so long a period as you may

     Underwriters or their counsel in qualifying the Stock under state
     securities or blue sky laws and in the review of the offering by the NASD.

     of Hambrecht & Quist LLC on behalf of the Underwriters, the Company will
     not, for a period of 180 days following the commencement of the public
     offering of the Stock by the Underwriters, directly or indirectly, (i)

     Stock or (ii) enter into any swap or other agreement that transfers, in
     whole or in part, any of the economic consequences or ownership of Common
     Stock, whether any such transaction described in clause (i) or (ii) above
     is to be settled by delivery of Common Stock or such other securities, in
     cash or otherwise.  The foregoing sentence shall not apply to (A) the Stock
     to be sold to the Underwriters pursuant to this Agreement, (B) shares of
     Common Stock issued by the Company upon the exercise of options granted
     under the stock option plans of the Company (the "Option Plans") or upon
     the exercise of warrants outstanding as of the date hereof, all as
     described in footnote ___ to the table under the caption "Capitalization"
     in the Preliminary Prospectus, and (C) options to purchase Common Stock
     granted under the Option Plans.

          (l)  The Company agrees to use its best efforts to cause all
     directors, officers, and stockholders to agree that, without the prior
     written consent of Hambrecht & Quist LLC on behalf of the Underwriters,
     such person or entity will not, for a period of 180 days following the
     commencement of the public offering of the Stock by the Underwriters,
     directly or indirectly, (i) sell, offer, contract to sell, make any short
     sale, pledge, sell any option or contract to purchase, purchase any option
     or contract to sell, grant any option, right or warrant to purchase or

          (m)  The Company agrees:  (i) to enforce the terms of each Lock-up
     Agreement and (ii) issue stop-transfer instructions to the transfer agent
     for the Common Stock with respect to any transaction or contemplated
     transaction that would constitute a breach of or default under the
     applicable Lock-up Agreement.  In addition, except with the prior written
     consent of Hambrecht & Quist LLC, the Company agrees (i) not to amend or
     terminate, or waive any right under, any Lock-up Agreement, or take any
     other action that would directly or indirectly have the same effect as an
     amendment or termination, or waiver of any right under, any Lock-up
     Agreement, that would permit any holder of shares of Common Stock, or
     securities convertible into or exercisable or exchangeable for Common
     Stock, to sell, make any short sale of, grant any option for the purchase
     of, or otherwise transfer or dispose of, any of such shares of Common Stock
     or other securities prior to the expiration of 180 days after the date of
     the Prospectus, and (ii) not to consent to any sale, short sale, grant of
     an option for the purchase of, or other disposition or transfer of shares

          (n)  If at any time during the 25-day period after the Registration

                                                          SUBJECT TO NEGOTIATION


     (regardless of whether such rumor, publication or event necessitates a
     supplement to or amendment of the Prospectus), the Company will, after
     written notice from you advising the Company to the effect set forth above,
     forthwith prepare, consult with you concerning the substance of, and
     disseminate a press release or other public statement, reasonably
     satisfactory to you, responding to or commenting on such rumor, publication
     or event.

          (o)  The Company is familiar with the Investment Company Act of 1940,
     as amended, and has in the past conducted its affairs, and will in the
     future conduct its affairs, in such a manner to ensure that the Company was
     not and will not be an "investment company" or a company "controlled" by an
     "investment company" within the meaning of the Investment Company Act of
     1940, as amended, and the rules and regulations thereunder.

     7.   INDEMNIFICATION AND CONTRIBUTION.

          (a)  The Company agrees to indemnify and hold harmless each
Underwriter and each person (including each partner or officer thereof) who
controls any Underwriter within the meaning of Section 15 of the Securities Act
from and against any and all losses, claims, damages or liabilities, joint or
several, to which such indemnified parties or any of them may become subject
under the Securities Act, the Securities Exchange Act of 1934, as amended
(herein called the "Exchange Act"), or the common law or otherwise, and the
Company agrees to reimburse each such Underwriter and controlling person for any
legal or other expenses (including, except as otherwise hereinafter provided,
reasonable fees and disbursements of counsel) incurred by the respective
indemnified parties in connection with defending against any such losses,
claims, damages or liabilities or in connection with any investigation or
inquiry of, or other proceeding which may be brought against, the respective
indemnified parties, in each case arising out of or based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (including the Prospectus as part thereof and any Rule
462(b) registration statement) or any post-effective amendment thereto
(including any Rule 462(b) registration statement), or the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or (ii) any untrue
statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus or the Prospectus (as amended or as supplemented if the
Company shall have filed with the Commission any amendment thereof or supplement
thereto) or the omission or alleged omission to state therein a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided, however,
that (1) the indemnity agreements of the Company contained in this paragraph (a)
shall not apply to any such losses, claims, damages, liabilities or expenses if
such statement or omission was made in reliance upon and in conformity with
information furnished as herein stated or otherwise furnished in writing to the
Company by or on behalf of any Underwriter for use in any Preliminary Prospectus
or the Registration Statement or the Prospectus or any such amendment thereof or
supplement thereto and (2) the indemnity agreement contained in this paragraph
(a) with respect to any Preliminary Prospectus shall not inure to the benefit of
any Underwriter from whom the person asserting any such losses, claims, damages,
liabilities or expenses purchased the Stock which is the subject thereof (or to
the benefit of any person controlling such Underwriter) if at or prior to the
written confirmation of the sale of such Stock a copy of the Prospectus (or the
Prospectus as amended or supplemented) was not sent or delivered to such person
and the untrue statement or omission of a material fact contained in such
Preliminary Prospectus was corrected in the Prospectus (or the Prospectus as
amended or supplemented) unless the failure is the result of noncompliance by
the Company with paragraph (c) of Section 6 hereof. The indemnity agreements of
the Company contained in this paragraph (a) and the representations and
warranties of the Company contained in Section 2 hereof shall remain operative
and in full force and effect regardless of any investigation made by or on
behalf of any indemnified party and shall survive the delivery of and payment
for the Stock.

                                                               PRELIMINARY DRAFT
                                                          SUBJECT TO NEGOTIATION


          (b)  Each Underwriter severally agrees to indemnify and hold harmless
the Company, each of its officers who signs the Registration Statement on his
own behalf or pursuant to a power of attorney, each of its directors, each other
Underwriter and each person (including each partner or officer thereof) who
controls the Company or any such other Underwriter within the meaning of Section
15 of the Securities Act, from and against any and all losses, claims, damages
or liabilities, joint or several, to which such indemnified parties or any of
them may become subject under the Securities Act, the Exchange Act, or the
common law or otherwise and to reimburse each of them for any legal or other
expenses (including, except as otherwise hereinafter provided, reasonable fees
and disbursements of counsel) incurred by the respective indemnified parties in
connection with defending against any such losses, claims, damages or
liabilities or in connection with any investigation or inquiry of, or other
proceeding which may be brought against, the respective indemnified parties, in
each case arising out of or based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement
(including the Prospectus as part thereof and any Rule 462(b) registration
statement) or any post-effective amendment thereto (including any Rule 462(b)
registration statement) or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading or (ii) any untrue statement or alleged untrue statement
of a material fact contained in the Prospectus (as amended or as supplemented if
the Company shall have filed with the Commission any amendment thereof or
supplement thereto) or the omission or alleged omission to state therein a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading, if such statement
or omission was made in reliance upon and in conformity with information
furnished as herein stated or otherwise furnished in writing to the Company by
or on behalf of such indemnifying Underwriter for use in the Registration
Statement or the Prospectus or any such amendment thereof or supplement thereto.
The indemnity agreement of each Underwriter contained in this paragraph (b)
shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any indemnified party and shall survive
the delivery of and payment for the Stock.

          (c)  Each party indemnified under the provision of paragraphs (a) and
(b) of this Section 7 agrees that, upon the service of a summons or other
initial legal process upon it in any action or suit instituted against it or
upon its receipt of written notification of the commencement of any
investigation or inquiry of, or proceeding against, it in respect of which
indemnity may be sought on account of any indemnity agreement contained in such
paragraphs, it will promptly give written notice (herein called the Notice) of
such service or notification to the party or parties from whom indemnification
may be sought hereunder.  No indemnification provided for in such paragraphs
shall be available to any party who shall fail so to give the Notice if the
party to whom such Notice was not given was unaware of the action, suit,
investigation, inquiry or proceeding to which the Notice would have related and
was prejudiced by the failure to give the Notice, but the omission so to notify
such indemnifying party or parties of any such service or notification shall not
relieve such indemnifying party or parties from any liability which it or they
may have to the indemnified party for contribution or otherwise than on account
of such indemnity agreement.  Any indemnifying party shall be entitled at its
own expense to participate in the defense of any action, suit or proceeding
against, or investigation or inquiry of, an indemnified party.  Any indemnifying
party shall be entitled, if it so elects within a reasonable time after receipt
of the Notice by giving written notice (herein called the "Notice of Defense")
to the indemnified party, to assume (alone or in conjunction with any other
indemnifying party or parties) the entire defense of such action, suit,
investigation, inquiry or proceeding, in which event such defense shall be
conducted, at the expense of the indemnifying party or parties, by counsel
chosen by such indemnifying party or parties and reasonably satisfactory to the
indemnified party or parties; provided, however, that (i) if the indemnified
party or parties reasonably determine that there may be a conflict between the
positions of the indemnifying party or parties and of the indemnified party or
parties in conducting the defense of such action, suit, investigation, inquiry
or proceeding or that there may be legal defenses available to such indemnified
party or parties different from or in addition to those available to the
indemnifying party or parties, then counsel for the indemnified party or parties
shall be entitled to conduct the defense to the extent

                                                               PRELIMINARY DRAFT
                                                          SUBJECT TO NEGOTIATION


reasonably determined by such counsel to be necessary to protect the interests
of the indemnified party or parties and (ii) in any event, the indemnified party
or parties shall be entitled to have counsel chosen by such indemnified party or
parties participate in, but not conduct, the defense. If, within a reasonable
time after receipt of the Notice, an indemnifying party gives a Notice of
Defense and the counsel chosen by the indemnifying party or parties is
reasonably satisfactory to the indemnified party or parties, the indemnifying
party or parties will not be liable under paragraphs (a) through (c) of this
Section 7 for any legal or other expenses subsequently incurred by the
indemnified party or parties in connection with the defense of the action, suit,
investigation, inquiry or proceeding, except that (A) the indemnifying party or
parties shall bear the legal and other expenses incurred in connection with the
conduct of the defense as referred to in clause (i) of the proviso to the
preceding sentence and (B) the indemnifying party or parties shall bear such
other expenses as it or they have authorized to be incurred by the indemnified
party or parties. If, within a reasonable time after receipt of the Notice, no
Notice of Defense has been given, the indemnifying party or parties shall be
responsible for any legal or other expenses incurred by the indemnified party or
parties in connection with the defense of the action, suit, investigation,
inquiry or proceeding.

          (d)  If the indemnification provided for in this Section 7 is
unavailable or insufficient to hold harmless an indemnified party under
paragraph (a) or (b) of this Section 7, then each indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in paragraph (a) or (b) of this Section 7 (i) in such
proportion as is appropriate to reflect the relative benefits received by each
indemnifying party from the offering of the Stock or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of each indemnifying party in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, or actions in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Company and the Underwriters shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Stock received by
the Company and the total underwriting discount received by the Underwriters, as
set forth in the table on the cover page of the Prospectus, bear to the
aggregate public offering price of the Stock. Relative fault shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by each indemnifying party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission.

     The parties agree that it would not be just and equitable if contributions
pursuant to this paragraph (d) were to be determined by pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by any
other method of allocation which does not take into account the equitable
considerations referred to in the first sentence of this paragraph (d).  The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities, or actions in respect thereof, referred to in the first sentence
of this paragraph (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigation,
preparing to defend or defending against any action or claim which is the
subject of this paragraph (d). Notwithstanding the provisions of this paragraph
(d), no Underwriter shall be required to contribute any amount in excess of the
underwriting discount applicable to the Stock purchased by such Underwriter. 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.  The Underwriters'
obligations in this paragraph (d) to contribute are several in proportion to
their respective underwriting obligations and not joint.

     Each party entitled to contribution agrees that upon the service of a
summons or other initial legal process upon it in any action instituted against
it in respect of which contribution may be sought, it will promptly give written
notice of such service to the party or parties from whom contribution may be
sought, but the omission so to notify such party or parties of any such service
shall not relieve the party from whom contribution may be sought

from any obligation it may have hereunder or otherwise (except as specifically
provided in paragraph (c) of this Section 7).

          (e)  The Company will not, without the prior written consent of each
Underwriter, settle or compromise or consent to the entry of any judgment in any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not such Underwriter or any
person who controls such Underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act is a party to such claim,
action, suit or proceeding) unless such settlement, compromise or consent
includes an unconditional release of such Underwriter and each such controlling
person from all liability arising out of such claim, action, suit or proceeding.

     8.   TERMINATION.  This Agreement may be terminated by you at any time
prior to the Closing Date by giving written notice to the Company if after the
date of this Agreement trading in the Common Stock shall have been suspended, or
if there shall have occurred (i) the engagement in hostilities or an escalation
of major hostilities by the United States or the declaration of war or a
national emergency by the United States on or after the date hereof, (ii) any
outbreak of hostilities or other national or international calamity or crisis or
change in economic or political conditions if the effect of such outbreak,
calamity, crisis or change in economic or political conditions in the financial
markets of the United States would, in the Underwriters' reasonable judgment,
make the offering or delivery of the Stock impracticable, (iii) suspension of
trading in securities generally or a material adverse decline in value of
securities generally on the New York Stock Exchange, the American Stock
Exchange, The Nasdaq Stock Market, or limitations on prices (other than
limitations on hours or numbers of days of trading) for securities on either
such exchange or system, (iv) the enactment, publication, decree or other
promulgation of any federal or state statute, regulation, rule or order of, or
commencement of any proceeding or investigation by, any court, legislative body,
agency or other governmental authority which in the Underwriters' reasonable
opinion materially and adversely affects or will materially or adversely affect
the business or operations of the Company, (v) declaration of a banking
moratorium by either federal or New York State authorities or (vi) the taking of
any action by any federal, state or local government or agency in respect of its
monetary or fiscal affairs which in the Underwriters' reasonable opinion has a
material adverse effect on the securities markets in the United States. If this
Agreement shall be terminated pursuant to this Section 8, there shall be no
liability of the Company to the Underwriters and no liability of the
Underwriters to the Company; provided, however, that in the event of any such
termination the Company agrees to indemnify and hold harmless the Underwriters
from all costs or expenses incident to the performance of the obligations of the
Company under this Agreement, including all costs and expenses referred to in
paragraphs (i) and (j) of Section 6 hereof.

     9.   CONDITIONS OF UNDERWRITERS' OBLIGATIONS.  The obligations of the
several Underwriters to purchase and pay for the Stock shall be subject to the
performance by the Company of all its obligations to be performed hereunder at
or prior to the Closing Date or any later date on which Option Stock is to be
purchased, as the case may be, and to the following further conditions:

          (a)  The Registration Statement shall have become effective; and no
     stop order suspending the effectiveness thereof shall have been issued and
     no proceedings therefor shall be pending or threatened by the Commission.

     and the validity and form of the certificates representing the Stock, all
     corporate proceedings and other legal matters incident to the foregoing,
     and the form of the Registration Statement and of the Prospectus (except as
     to the financial statements contained therein), shall have been approved at
     or prior to the Closing Date by Wilson Sonsini Goodrich & Rosati, counsel
     for the Underwriters.

     in or affecting the business, properties, financial condition or results of
     operations of the Company and its subsidiaries, taken as a whole, whether

     are true and correct in all material respects as of the Closing Date or any
     later date on which Option Stock is to be purchased, as the case may be,
     and (viii) there has not been any material change in the market for
     securities in general or in political, financial or economic conditions
     from those reasonably foreseeable as to render it impracticable in your
     reasonable judgment to make a public offering of the Stock, or a material
     adverse change in market levels for securities in general (or those of
     companies in particular) or financial or economic conditions which render
     it inadvisable to proceed.

          (e)  You shall have received on the Closing Date and on any later date
     on which Option Stock is purchased a certificate, dated the Closing Date or
     such later date, as the case may be, and signed by the President and the
     Chief Financial Officer of the Company, stating that the respective signers
     of said certificate have carefully examined the Registration Statement in
     the form in which it originally became effective and the Prospectus
     contained therein and any supplements or amendments thereto, and that the
     statements included in clauses (i) through (vii) of paragraph (d) of this
     Section 9 are true and correct.

          (f)  You shall have received from Coopers & Lybrand L.L.P., a letter
     or letters, addressed to the Underwriters and dated the Closing Date and
     any later date on which Option Stock is purchased, confirming that they are
     independent public accountants with respect to the Company within the
     meaning of the Securities Act and the applicable published rules and
     regulations thereunder and based upon the procedures described in their
     letter delivered to you concurrently with the execution of this Agreement
     (herein called the Original Letter), but carried out to a date not more
     than three business days prior to the Closing Date or such later date on
     which Option Stock is purchased (i) confirming, to the extent true, that

     the statements and conclusions set forth in the Original Letter are
     accurate as of the Closing Date or such later date, as the case may be, and
     (ii) setting forth any revisions and additions to the statements and
     conclusions set forth in the Original Letter which are necessary to reflect
     any changes in the facts described in the Original Letter since the date of
     the Original Letter or to reflect the availability of more recent financial
     statements, data or information. The letters shall not disclose any change,
     or any development involving a prospective change, in or affecting the
     business or properties of the Company or any of its subsidiaries which, in
     your sole judgment, makes it impractical or inadvisable to proceed with the
     public offering of the Stock or the purchase of the Option Stock as
     contemplated by the Prospectus.

          (g)  You shall have received from Coopers & Lybrand L.L.P. a letter
     stating that their review of the Company's system of internal accounting
     controls, to the extent they deemed necessary in establishing the scope of
     their examination of the Company's financial statements as at September 30,
     1997, did not disclose any weakness in internal controls that they
     considered to be material weaknesses.

          (h)  You shall have been furnished evidence in usual written or
     telegraphic form from the appropriate authorities of the several
     jurisdictions, or other evidence satisfactory to you, of the qualification
     referred to in paragraph (f) of Section 6 hereof.

          (i)  Prior to the Closing Date, the Stock to be issued and sold by the
     Company shall have been duly authorized for listing by the Nasdaq National
     Market upon official notice of issuance.

          (j)  On or prior to the Closing Date, you shall have received from all
     directors, officers and stockholders agreements, in form reasonably
     satisfactory to Hambrecht & Quist LLC, stating that without the prior
     written consent of Hambrecht & Quist LLC on behalf of the Underwriters,
     such person or entity will not, for a period of 180 days following the
     commencement of the public offering of the Stock by the Underwriters,
     directly or indirectly, (i) sell, offer, contract to sell, make any short
     sale, pledge, sell any option or contract to purchase, purchase any option
     or contract to sell, grant any option, right or warrant to purchase or
     otherwise transfer or dispose of any shares of Common Stock or any
     securities convertible into or exchangeable or exercisable for or any
     rights to purchase or acquire Common Stock or (ii) enter into any swap or
     other agreement that transfers, in whole or in part, any of the economic
     consequences or ownership of Common Stock, whether any such transaction
     described in clause (i) or (ii) above is to be settled by delivery of
     Common Stock or such other securities, in cash or otherwise.

     All the agreements, opinions, certificates and letters mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if  Wilson Sonsini Goodrich & Rosati, counsel for the
Underwriters, shall be satisfied that they comply in form and scope.

     In case any of the conditions specified in this Section 9 shall not be
fulfilled, this Agreement may be terminated by you by giving notice to the
Company.  Any such termination shall be without liability of the Company to the
Underwriters and without liability of the Underwriters to the Company; provided,
however, that (i) in the event of such termination, the Company agrees to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the performance of the obligations of the Company under this Agreement,
including all costs and expenses referred to in paragraphs (i) and (j) of
Section 6 hereof, and (ii) if this Agreement is terminated by you because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein, to fulfill any of the conditions herein, or to comply with any
provision hereof other than by reason of a default by any of the Underwriters,
the Company will reimburse the Underwriters severally upon demand for all out-
of-pocket expenses (including reasonable fees and disbursements of counsel) that
shall have been incurred by them in connection with the transactions
contemplated hereby.

     10.  CONDITIONS OF THE OBLIGATION OF THE COMPANY.  The obligation of the
Company to deliver the Stock shall be subject to the conditions that (a) the
Registration Statement shall have become effective and (b) no stop order
suspending the effectiveness thereof shall be in effect and no proceedings
therefor shall be pending or threatened by the Commission.

     In case either of the conditions specified in this Section 10 shall not be
fulfilled, this Agreement may be terminated by the Company by giving notice to
you.  Any such termination shall be without liability of the Company to the
Underwriters and without liability of the Underwriters to the Company; provided,
however, that in the event of any such termination the Company agrees to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the performance of the obligations of the Company under this Agreement,
including all costs and expenses referred to in paragraphs (i) and (j) of
Section 6 hereof.

     11.  REIMBURSEMENT OF CERTAIN EXPENSES.  In addition to its other
obligations under Section 7 of this Agreement, the Company hereby agrees to
reimburse on a quarterly basis the Underwriters for all reasonable legal and
other expenses incurred in connection with investigating or defending any claim,
action, investigation, inquiry or other proceeding arising out of or based upon
any statement or omission, or any alleged statement or omission, described in
paragraph (a) of Section 7 of this Agreement, notwithstanding the absence of a
judicial determination as to the propriety and enforceability of the obligations
under this Section 11 and the possibility that such payments might later be held
to be improper; provided, however, that (i) to the extent any such payment is
ultimately held to be improper, the persons receiving such payments shall
promptly refund them and (ii) such persons shall provide to the Company, upon
request, reasonable assurances of their ability to effect any refund, when and
if due.

     12.  PERSONS ENTITLED TO BENEFIT OF AGREEMENT.  This Agreement shall inure
to the benefit of the Company and the several Underwriters and, with respect to
the provisions of Section 7 hereof, the several parties (in addition to the
Company and the several Underwriters) indemnified under the provisions of said
Section 7, and their respective personal representatives, successors and
assigns. Nothing in this Agreement is intended or shall be construed to give to
any other person, firm or corporation any legal or equitable remedy or claim
under or in respect of this Agreement or any provision herein contained.  The
term "successors and assigns" as herein used shall not include any purchaser, as
such purchaser, of any of the Stock from any of the several Underwriters.

     13.  NOTICES.  Except as otherwise provided herein, all communications
hereunder shall be in writing or by telegraph and, if to the Underwriters, shall
be mailed, telegraphed or delivered to Hambrecht & Quist LLC, One Bush Street,

shall be promptly confirmed by letter.

     14.  MISCELLANEOUS.  The reimbursement, indemnification and contribution
agreements contained in this Agreement and the representations, warranties and
covenants in this Agreement shall remain in full force and effect regardless of
(a) any termination of this Agreement, (b) any investigation made by or on
behalf of any Underwriter or controlling person thereof, or by or on behalf of
the Company or their respective directors or officers, and (c) delivery and
payment for the Stock under this Agreement; provided, however, that if this
Agreement is terminated prior to the Closing Date, the provisions of paragraphs
(k) and (l) of Section 6 hereof shall be of no further force or effect.

     This Agreement may be executed in two or more counterparts, each of which
shall be deemed an original, but all of which together shall constitute one and
the same instrument.

     under the laws of the jurisdiction of its incorporation, is duly qualified
     as a foreign corporation and in good standing in each state of the United
     States of America in which its ownership or leasing of property requires
     such qualification (except where the failure to be so qualified would not
     have a material adverse effect on the business, properties, financial
     condition or results of operations of the Company and its subsidiaries,
     taken as a whole), and has full corporate power and authority to own or
     lease its properties and conduct its business as described in the

     each of the subsidiaries of the Company has been duly authorized and
     validly issued and is fully paid and nonassessable, and is owned by the

     and to the best of such counsel's knowledge, no options, warrants or other

     interests in such subsidiaries are outstanding;

          (ii)   the authorized capital stock of the Company consists of

     financial data contained or incorporated by reference therein, as to which
     such counsel need not express any opinion or belief) at the Effective Date
     contained any untrue statement of a material fact or omitted to state a

     state a material fact necessary in order to make the statements therein, in
     light of the circumstances under which they were made, not misleading;

          (a)  Upon the Effective Date of the Merger, the Surviving Corporation
shall assume the obligations of Preview Travel-California under Preview Travel-
California's 1988 Stock Option Plan, 1997 Stock Option Plan, 1997 Employee Stock
Purchase Plan, 1997 Directors' Stock Incentive Plan and all other employee
benefit plans of Preview Travel-California. Each outstanding and unexercised
option, other right to purchase, or security convertible into, Preview Travel-
California Common Stock or Preferred Stock (a "Right") shall become, subject to
                                               -----                           
the provisions in paragraph (c) hereof, an option, right to purchase, or a
security convertible into the Surviving Corporation's Common Stock or Preferred
Stock, respectively, on the basis of one share of the Surviving Corporation's
Common Stock or Preferred Stock, as the case may be, for each two (2) shares of
Preview Travel-California Common Stock or Preferred Stock, issuable pursuant to
any such Right, on the same terms and conditions and at an exercise price equal
to the product of two times the exercise price applicable to any such Preview
Travel-California Right at the Effective Date of the Merger. This paragraph
3.3(a) shall not apply to Preview Travel-California Common Stock or Preferred
Stock. Such Common Stock and Preferred Stock are subject to paragraph 3.1 and
3.2 hereof , respectively.

          (b)  A number of shares of the Surviving Corporation's Common Stock
and Preferred Stock shall be reserved for issuance upon the exercise or
conversion of Rights equal to the one share of Preview Travel-Delaware for two
shares of Preview Travel-California Common Stock and Preferred Stock so reserved
immediately prior to the Effective Date of the Merger.

          (c)  The assumed Rights shall not entitle any holder thereof to a
fractional share upon exercise or conversion. In lieu thereof, any fractional
share interests to which a holder of an assumed Right (other than an option
issued pursuant to Preview Travel-Delaware's California's 1988 Stock Option
Plan, 1997 Stock Option Plan, 1997 Employee Stock Purchase Plan, 1997 Directors'
Stock Incentive Plan) would otherwise be entitled upon exercise or conversion
shall be aggregated (but only with other similar Rights which have the same per

be entitled to a fractional share with respect thereto upon exercise or
conversion, the holder shall be entitled upon the exercise or conversion of all
such assumed Rights pursuant to their terms (as modified herein), to one full
share of Common Stock or Preferred Stock in lieu of such fractional share. With
respect to each class of such similar Rights, no holder will be entitled to more
than one full share in lieu of a fractional share upon exercise or conversion.

     Notwithstanding the foregoing, with respect to options issued under the
Preview Travel-California's 1988 Stock Option Plan, 1997 Stock Option Plan, 1997
Employee Stock Purchase Plan, 1997 Directors' Stock Incentive Plan that are
assumed in the Merger, the number of shares of Common Stock to which the holder
would be otherwise entitled upon exercise of each such 

                                      -4-

assumed option following the Merger shall be rounded down to the nearest whole
number and the exercise price shall be rounded up to the nearest whole cent. In
addition, no "additional benefits" (within the meaning of Section 424(a)(2) of
the Internal Revenue Code of 1986, as amended) shall be accorded to the
optionees pursuant to the assumption of their options.

     3.4  PREVIEW TRAVEL-DELAWARE COMMON STOCK.  Upon the Effective Date of the
          ------------------------------------                                 
Merger, each share of Common Stock, $0.001 par value, of Preview Travel issued
and outstanding immediately prior thereto shall, by virtue of the Merger and
without any action by Preview Travel-Delaware, the holder of such shares or any
other person, be canceled and returned to the status of authorized but unissued
shares.

     3.5  EXCHANGE OF CERTIFICATES.  After the Effective Date of the Merger,
          ------------------------                                          
each holder of an outstanding certificate representing shares of Preview Travel-
California Common Stock or Preferred Stock may be asked to surrender the same
for cancellation to an exchange agent, whose name will be delivered to holders
prior to any requested exchange  (the "Exchange Agent"), and each such holder
                                       --------------                        
shall be entitled to receive in exchange therefor a certificate or certificates
representing the number of shares of the appropriate class and series of the
Surviving Corporation's capital stock into which the surrendered shares were
converted as herein provided.  Until so surrendered, each outstanding
certificate theretofore representing shares of Preview Travel-California capital
stock shall be deemed for all purposes to represent the number of whole shares
of the appropriate class and series of the Surviving Corporation's capital stock
into which such shares of Preview Travel-California capital stock were converted
in the Merger.

     The registered owner on the books and records of the Surviving Corporation
or the Exchange Agent of any such outstanding certificate shall, until such
certificate shall have been surrendered for transfer or conversion or otherwise
accounted for to the Surviving Corporation or the Exchange Agent, have and be
entitled to exercise any voting and other rights with respect to and to receive
dividends and other distributions upon the shares of capital stock of the
Surviving Corporation represented by such outstanding certificate as provided
above.

     Each certificate representing capital stock of the Surviving Corporation so
issued in the Merger shall bear the same legends, if any, with respect to the
restrictions on transferability as the certificates of Preview Travel-California
so converted and given in exchange therefor, unless otherwise determined by the
Board of Directors of the Surviving Corporation in compliance with applicable
laws.

     If any certificate for shares of Surviving Corporation's stock is to be
issued in a name other than that in which the certificate surrendered in
exchange therefor is registered, it shall be a condition of issuance thereof
that the certificate so surrendered shall be properly endorsed and otherwise in
proper form for transfer, that such transfer otherwise be proper and comply with
applicable securities laws and that the person requesting such transfer pay to
the Exchange Agent any transfer or other taxes payable by reason of the issuance
of such new certificate in a name other than that of the registered holder of
the certificate surrendered or establish to the satisfaction of the Surviving
Corporation that such tax has been paid or is not payable.

          -----------------                                                
Corporation shall be issued. Any fractional share interests to which a holder
would otherwise be entitled shall be aggregated so that no Preview Travel-
California shareholder shall receive cash in an amount greater than the value of
one (1) full share of Preview Travel-Delaware Common Stock.

imposed on the Series A, Series B, Series C, Series D and Series E Preferred
Stock and the holders thereof is as follows:

          (1)  Dividends.
               --------- 

               (aa) The holders of outstanding Series A Preferred Stock shall be
entitled to receive in any fiscal year, when and as declared by the Board of
Directors, out of any assets at the time legally available therefor, dividends
in cash at the rate of $0.12 per share of Series A Preferred Stock per annum,
the holders of outstanding Series B Preferred Stock shall be entitled to
receive, in any fiscal year, when and as declared by the Board of Directors, out
of any assets at the time legally available therefor, dividends in cash at the
rate of $0.12 per share of Series B Preferred Stock per annum, the holders of
outstanding Series C Preferred Stock shall be entitled to receive, in any fiscal
year, when and as declared by the Board of Directors, out of any assets at the
time legally available therefor, dividends in cash at the rate of $0.168 per
share of Series C Preferred Stock per annum, the holders of outstanding Series D
Preferred Stock shall be entitled to receive, in any fiscal year, when and as
declared by the Board of Directors, out of any assets at the time legally
available therefor, dividends in cash at the rate of $0.252 per share of Series
D Preferred Stock per annum, and the holders of outstanding Series E Preferred
Stock shall be entitled to receive, in any fiscal year, when and as declared by
the Board of Directors, out of any assets at the time legally available
therefor, dividends in cash at the rate of $0.54 per share of Series E Preferred
Stock per annum, before any cash dividend is paid on Common Stock.  Such
dividend or distribution may be payable annually or otherwise as the Board of
Directors may from time to time determine.  No dividend shall be declared with
respect to any series of Preferred Stock unless a dividend is declared with
respect to each series of outstanding Preferred Stock at a rate that is no less
favorable to the Series A, Series B, Series C, Series D and Series E Preferred
Stock than $0.12, $0.12, $0.168, $0.252 and $0.54 for each share of Series A,
Series B, Series C, Series D and Series E Preferred Stock, respectively.
Dividends or distributions (other than dividends payable solely in shares of
Common Stock) may be declared

                                      -2-
<PAGE>
 
and paid upon shares of Common Stock in any fiscal year of the corporation only
if dividends shall have been paid on or declared and set apart upon all shares
of Series A, Series B, Series C, Series D and Series E Preferred Stock at such
annual rate; and no further dividends shall be paid to holders of shares of
Series A, Series B, Series C, Series D or Series E Preferred Stock in excess of
such annual rate in any fiscal year unless at the same time equivalent dividends
are paid to holders of shares of Common Stock. The right to such dividends on
shares of Preferred Stock shall not be cumulative and no right shall accrue to
holders of shares of Preferred Stock by reason of the fact that dividends on
said shares are not declared in any prior year, nor shall any undeclared or
unpaid dividend bear or accrue interest.

               (bb) In the event this corporation shall declare a distribution
payable in securities of other persons, evidences of indebtedness issued by this
corporation or other persons, assets (excluding cash dividends) or options or
rights to purchase any such securities or evidences of indebtedness, then, in
each such case the holders of the Series A, Series B, Series C, Series D and
Series E Preferred Stock shall be entitled to a proportionate share of any such
distribution as though the holders of the Series A, Series B, Series C, Series D
and Series E Preferred Stock were the holders of the number of shares of Common
Stock of the corporation into which their respective shares of Series A, Series
B, Series C, Series D and Series E  Preferred Stock are convertible as of the
record date fixed for the determination of the holders of Common Stock of the
corporation entitled to receive such distribution.

          (2)  Voting Rights.
               ------------- 

               (aa) General Voting Rights. Except as otherwise required by law
                    ---------------------
or as provided herein, each holder of shares of the Series A, Series B, Series
C, Series D and Series E Preferred Stock shall be entitled to the number of
votes equal to the number of shares of Common Stock into which such shares of
Preferred Stock could be converted on the record date for the vote or consent of
shareholders and shall have voting rights and powers equal to the voting rights
and powers of the Common Stock. The holder of each share of the Series A, Series
B, Series C, Series D and Series E Preferred Stock shall be entitled to notice
of any shareholders' meeting in accordance with the Bylaws of the corporation
and shall vote with holders of the Common Stock upon the election of directors
and upon any other matter submitted to a vote of shareholders, except those
matters required by law or by paragraph (b)(2)(bb) to be submitted to a class
vote. Fractional votes by the holders of Series A, Series B, Series C, Series D
and Series E Preferred Stock shall not, however, be permitted and any fractional
voting rights resulting from the above formula (after aggregating all shares
into which shares of Series A, Series B, Series C, Series D or Series E
Preferred Stock held by each holder could be converted) shall be rounded to the
nearest whole number.

                    In addition, as long as the shareholders to which the Series
E Preferred Stock was first issued own at least sixty-six and two-thirds percent
(66 2/3%) of the shares originally purchased by them, the holders of the Series
E Preferred Stock shall be entitled, voting together as a separate class, to
elect two (2) directors of this corporation at each annual election of
directors. The holders of Preferred Stock and Common Stock voting together as a
single class shall have the right to elect any remaining directors.

                    -----------------------------------------------
any shares of Series D Preferred Stock are outstanding, this corporation shall
not, without first obtaining the approval by vote or written consent, in the
manner provided by law, of the holders of at least a majority (except with
respect to clause (iii) below, in which case the fraction required shall be at
least two-thirds (2/3)) of the total number of shares of Series D Preferred
Stock outstanding, voting separately as a class:

                    (i)   amend or repeal any provision of, or add any provision
to, the corporation's Certificate of Incorporation or Bylaws if such action
would adversely affect the rights, preferences or privileges of the Series D
Preferred Stock; or

                    (ii)  authorize or issue, or obligate itself to issue, any
other equity security senior to or on a parity with the Series D Preferred Stock
as to dividend or redemption rights, liquidation preferences, conversion rights,
voting rights or otherwise, or create any obligation or security convertible
into or exchangeable for, or having any option rights to purchase, any such
equity security which is senior to or on a parity with the Series D Preferred
Stock; or

                    (iii) amend or repeal any provision of, or add any provision
to, the corporation's Certificate of Incorporation or Bylaws if such action
would change the rights, preferences or privileges of the Series D Preferred
Stock (other than a change described in clause (ii) above), or increase or
decrease (other than by redemption or conversion) the total number of authorized
shares of Preferred Stock designated as Series D Preferred Stock.

               (cc) Protective Provisions--Series E Preferred Stock. So long as
                    -----------------------------------------------
any shares of Series E Preferred Stock are outstanding, this corporation shall
not, without first obtaining the approval by vote or written consent, in the
manner provided by law, of the holders of at least a majority of the total
number of shares of Series E Preferred Stock outstanding, voting separately as a
class:

                    (i)   amend or repeal any provision of, or add any provision
to, the corporation's Certificate of Incorporation or Bylaws if such action
would adversely affect the rights, preferences or privileges of the Series E
Preferred Stock; or

                    (ii)  authorize or issue, or obligate itself to issue, any
other equity security senior to or on a parity with the Series E Preferred Stock
as to dividend or redemption rights, liquidation preferences, conversion rights,
voting rights or otherwise, or create any obligation or security convertible
into or exchangeable for, or having any option rights to purchase, any such
equity security which is senior to or on a parity with the Series E Preferred
Stock; or

                    (iii) amend or repeal any provision of, or add any provision
to, the corporation's Certificate of Incorporation or Bylaws if such action
would change the rights, preferences or privileges of the Series E Preferred
Stock (other than a change described in clause (ii) above), or increase or

shares of Preferred Stock designated as Series E Preferred Stock.

               (dd) Protective Provisions--Series D and Series E Preferred
                    ------------------------------------------------------
Stock. So long as any shares of Series D or Series E Preferred Stock are
- -----
outstanding, this corporation shall not, without first obtaining the approval by
vote or written consent, in the manner provided by law, of the holders of at
least two-thirds (2/3rds) of the total number of shares of Series D and Series E
Preferred Stock outstanding, voting together as a class on an as-converted-to-
Common Stock basis:

                    (i)   increase or decrease (other than by redemption or
conversion) the total number of authorized shares of Preferred Stock of the
corporation; or

                    (ii)  effect any sale or other conveyance of more than 50%
of the consolidated assets of the corporation, any consolidation or merger
involving the corporation or any of its subsidiaries or any transaction in which
more than 50% of the voting power of the corporation is disposed of; or

                    (iii) effect any liquidation, dissolution, reclassification,
recapitalization or reorganization with respect to the corporation or any of its
outstanding equity securities; or

                    (iv)  pay or declare any dividend or distribution on, or
redeem (other than pursuant to agreements with the holders thereof providing for
repurchase of shares of Common Stock upon termination of employment with or
services to the Corporation), any shares of Preferred Stock or Common Stock.

          (3)  Conversion.  The holders of the Series A, Series B, Series C,
               ----------                                                   
Series D and Series E Preferred Stock shall have conversion rights as follows
(the "Conversion Rights"):

               (aa) Right to Convert.
                    ---------------- 

                    (i)   Each share of Series A, Series B, Series C, Series D
and Series E Preferred Stock shall be convertible, at the option of the holder
thereof, at any time after the date of issuance of such share, at the office of
the corporation or any transfer agent for the Series A, Series B, Series C,
Series D and Series E Preferred Stock, into Common Stock. The number of shares
of Common Stock into which each share of Series A Preferred Stock may be
converted shall be equal to $2.00 divided by the Conversion Price for such
series (as hereinafter defined), the number of shares of Common Stock into which
each share of Series B Preferred Stock may be converted shall be equal to $2.00
divided by the Conversion Price for such series (as hereinafter defined), the
number of shares of Common Stock into which each share of Series C Preferred
Stock may be converted shall be equal to $2.80 divided by the Conversion Price
for such series (as hereinafter defined), the number of shares of Common Stock
into which each share of Series D Preferred Stock may be converted shall be
equal to $4.20 divided by the Conversion Price for such series (as hereinafter
defined), and the number of shares of Common Stock into which each share of
Series E Preferred Stock may be converted shall be equal to $9.00 divided by the
Conversion Price for such series (as hereinafter defined). The Conversion Prices
for the Series A, Series B, Series C, Series D and Series E Preferred Stock
shall initially be $2.00, $2.00, $2.80, $4.20 and $9.00, respectively, subject
to adjustment as provided herein.

                                      -5-
<PAGE>
 
(The number of shares of Common Stock into which each share of Series A, Series
B, Series C, Series D or Series E Preferred Stock may be converted is
hereinafter referred to as the "Conversion Rate" for each such series.)  Upon
any decrease or increase in the Conversion Price or the Conversion Rate for a
series, as described in this paragraph (b)(3), the Conversion Rate or Conversion
Price for such series, as the case may be, shall be appropriately increased or
decreased.

                    (ii)  Each share of Series A, Series B, Series C, Series D
and Series E Preferred Stock shall automatically be converted into shares of
Common Stock at the then effective Conversion Rate immediately upon the earlier
of (A) consummation of the corporation's sale of Common Stock pursuant to a
registration statement under the Securities Act of 1933, as amended (the
"Securities Act"), pursuant to an underwritten firm commitment public offering,
provided that the aggregate gross proceeds to the corporation, net of
underwriting discounts and commissions, exceed $7,500,000, and the price to the
public is at least $9.00 per share (subject to adjustment for stock splits,
stock dividends, recapitalizations and the like) or (B) the date specified by
written consent of at least 80% of the Series A, Series B, Series C, Series D
and Series E Preferred Stock (voting together as a class) then outstanding.

                    (iii) No fractional shares of Common Stock shall be issued
upon conversion of the Series A, Series B, Series C, Series D or Series E
Preferred Stock and any shares of Series A, Series B, Series C, Series D or
Series E Preferred Stock surrendered for conversion which would otherwise result
in a fractional share of Common Stock shall be redeemed for the then fair market
value thereof as determined by the corporation's Board of Directors, payable as
promptly as possible whenever funds are legally available therefor. If more than
one share of Series A, Series B, Series C, Series D or Series E Preferred Stock
is surrendered for conversion at any one time by the same holder, the number of
full shares of Common Stock to be issued upon conversion shall be computed on
the basis of the aggregate number of shares of Series A, Series B, Series C,
Series D or Series E Preferred Stock so surrendered.

               (bb) Mechanics of Conversion. Before any holder of Series A,
                    -----------------------
Series B, Series C, Series D or Series E Preferred Stock shall be entitled to
convert the same into shares of Common Stock, such holder shall surrender the
certificate or certificates therefor, duly endorsed, at the office of the
corporation or of any transfer agent for the Series A, Series B, Series C,
Series D and Series E Preferred Stock, and shall give written notice to the
corporation at such office that such holder elects to convert the same and shall
state therein the name or names in which such holder wishes the certificate or
certificates for shares of Common Stock to be issued. The corporation shall, as
soon as practicable thereafter, issue and deliver at such office to such holder
of Series A, Series B, Series C, Series D or Series E Preferred Stock, or to
such holder's nominee or nominees, a certificate or certificates for the number
of shares of Common Stock to which such holder shall be entitled as aforesaid.
Except as set forth in paragraph (b)(3)(aa)(ii) above, such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the shares of Series A, Series B, Series C, Series D or
Series E Preferred Stock to be converted, and the person or persons entitled to
receive the shares of Common Stock issuable upon such conversion shall be
treated for all

                                      -6-
<PAGE>
 
purposes as the record holder or holders of such shares of Common Stock on such
date. If the voluntary conversion is in connection with an underwritten offering
of securities registered pursuant to the Securities Act, the conversion may, at
the option of any Holder tendering said shares of Preferred Stock for
conversion, be conditioned upon the closing of the sale of such securities to
the underwriter pursuant to such offering, in which event the person(s) entitled
to receive the Common Stock issuable upon such conversion of the Preferred Stock
shall not be deemed to have converted such Preferred Stock until immediately
prior to such closing.

               (cc) Adjustment of Conversion Rate for Combinations of Common
                    --------------------------------------------------------
Stock. In the event the corporation at any time or from time to time after the
- -----     
effective date of a written agreement by the corporation for the initial sale of
Series E Preferred Stock (hereinafter referred to as the "Original Issue Date")
effects a combination of its outstanding Common Stock into a lesser number of
shares without a proportionate and corresponding combination of its outstanding
Series A, Series B, Series C, Series D and Series E Preferred Stock, then and in
each such event the Conversion Rate for the Series A, Series B, Series C, Series
D and Series E Preferred Stock shall be decreased proportionately effective upon
the close of business on the date of such combination.

               (dd) Adjustment of Conversion Rate for Splits, Subdivisions,
                    -------------------------------------------------------
Dividends, Distributions and Common Stock Equivalents.  In the event the
- -----------------------------------------------------                   
corporation at any time or from time to time after the Original Issue Date shall
make or issue, or fix a record date for the effectuation of a split or
subdivision of the outstanding shares of Common Stock or the determination of
holders of Common Stock entitled to receive a dividend or other distribution
payable in additional shares of Common Stock or other securities or rights
(hereinafter referred to as "Common Stock Equivalents") convertible into or
entitling the holder thereof to receive additional shares of Common Stock
without payment of any consideration by such holder for the additional shares of
Common Stock or such Common Stock Equivalents (including the additional shares
of Common Stock issuable upon conversion or exercise thereof), then and in each
such event the maximum number of shares (as set forth in the instrument relating
thereto without regard to any provisions contained therein for a subsequent
adjustment of such number) of Common Stock issuable in payment of such dividend
or distribution or upon conversion or exercise of such Common Stock Equivalents
shall be deemed to be issued and outstanding as of the time of such issuance or,
in the event such a record date shall have been fixed, as of the close of
business on such record date.  In each such event the Conversion Rate for the
Series A, Series B, Series C, Series D and Series E Preferred Stock shall be
increased as of the time of such issuance or, in the event such a record date
shall have been fixed, as of the close of business on such record date, by
multiplying the Conversion Rate for such series by a fraction,

                    (i)   the numerator of which shall be the total number of
shares of Common Stock issued and outstanding or deemed to be issued and
outstanding immediately prior to the time of such issuance or the close of
business on such record date plus the number of shares of Common Stock issuable
in payment of such dividend or distribution or upon conversion or exercise of
such Common Stock Equivalents; and

                                      -7-
<PAGE>
 
                    (ii)  the denominator of which shall be the total number of
shares of Common Stock issued and outstanding or deemed to be issued and
outstanding immediately prior to the time of such issuance or the close of
business on such record date; provided, however, (A) if such record date shall
have been fixed and such dividend is not fully paid or if such distribution is
not fully made on the date fixed therefor, the Conversion Rate for such series
shall be recomputed accordingly as of the close of business on such record date
and thereafter the Conversion Rate for such series shall be adjusted pursuant to
this paragraph (b)(3)(dd) as of the time of actual payment of such dividends or
distribution; (B) if such Common Stock Equivalents provide, with the passage of
time or otherwise, for any decrease in the number of shares of Common Stock
issuable upon conversion or exercise thereof, the Conversion Rate for such
series shall, upon any such decrease becoming effective, be recomputed to
reflect such decrease insofar as it affects the rights of conversion or exercise
of the Common Stock Equivalents then outstanding; and (C) upon the expiration of
any rights or conversion or exercise under any unexercised Common Stock
Equivalents, the Conversion Rate for such series computed upon the original
issue thereof shall, upon such expiration, be recomputed as if the only
additional shares of Common Stock issued were the shares of such stock, if any,
actually issued upon the conversion or exercise of such Common Stock
Equivalents.

               (ee) Sale of Shares Below Conversion Price. If at any time after
                    -------------------------------------
the Original Issue Date, the corporation shall issue or sell any shares of
Additional Stock (as defined below) without consideration or for a consideration
per share that is less than the then existing Conversion Price for a series of
Preferred Stock, then and in each such case, the Conversion Price for such
series shall be adjusted to a price (calculated to the nearest cent) determined
by multiplying such Conversion Price for such series by a fraction (1) the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such issue plus the number of shares of Common Stock which
the aggregate consideration received by the corporation for the total number of
shares of Additional Stock so issued would purchase if the purchase price per
share were equal to the then existing Conversion Price for such series, and (2)
the denominator of which shall be the number of shares of Common Stock
outstanding immediately prior to such issue plus the number of such shares of
Additional Stock so issued or sold. For purposes of this subsection (ee) the
shares of Common Stock issuable upon conversion of the Series A, Series B,
Series C, Series D and Series E Preferred Stock and any other outstanding
convertible securities of the corporation and upon exercise of options, warrants
or other outstanding securities of the corporation, shall be deemed to be
outstanding immediately prior to any such issue described above.

                    For the purpose of making an adjustment in the Conversion
Price for a series of Preferred Stock as provided above, the consideration
received by the corporation for any issue or sale of Additional Stock shall,

                    (1)   to the extent it consists of cash, be computed at the
net amount of cash received by the corporation after deduction of any expenses
payable by the corporation and any underwriting or similar commissions,
compensation, or concessions paid or allowed by the corporation in connection
with such issue or sale;

                                      -8-
<PAGE>
 
                    (2)   to the extent it consists of property other than cash,
be computed at the fair market value of that property as determined in good
faith by the corporation's Board of Directors; and

                    (3)   if Additional Stock is issued or sold together with
other stock or securities or other assets of the corporation for a consideration
which covers both, be computed as the portion of the consideration so received
that may be reasonably determined in good faith by the Board of Directors to be
allocable to such Additional Stock.

                    If the corporation shall (1) grant any rights or options
(other than rights or options issued to employees, officers, directors and
consultants of the corporation pursuant to plans or arrangements approved by the
Board of Directors of the corporation), to subscribe for, purchase, or otherwise
acquire shares of Additional Stock, or (2) issue or sell any security
convertible into shares of Additional Stock, then in each case, the price per
share of Additional Stock issuable on the exercise of the rights or options or
the conversion of the securities shall be determined by dividing the total
amount, if any, received or receivable by the corporation as consideration for
the granting of the rights or options or the issue or sale of the convertible
securities, plus the minimum aggregate amounts of additional consideration
payable (with the passage of time or otherwise) to the corporation on exercise
or conversion of the securities, by the maximum number of shares of Additional
Stock issuable (with the passage of time or otherwise) on the exercise or
conversion.

                    If the price per share so determined is less than the then
existing Conversion Price for a series of Preferred Stock, the granting or issue
or sale shall be deemed to be an issue or sale for cash of the maximum number of
shares of Additional Stock issuable (with the passage of time or otherwise) on
exercise or conversion at the price per share determined under this subsection,
and the Conversion Price for such series of Preferred Stock shall be adjusted as
above provided to reflect (on the basis of that determination) the issue or
sale. No further adjustment of the Conversion Price for such series of Preferred
Stock shall be made as a result of the actual issuance of shares of Additional
Stock on the exercise of any such rights or options or the conversion of any
such convertible securities.

                    If such rights or options or convertible securities by their
terms provide, with the passage of time or otherwise, for an increase in the
amount of additional consideration payable to the corporation or decrease in the
number of shares of Additional Stock issuable on such exercise or exchange (by
change of rate or otherwise), the Conversion Price for the Series A, Series B,
Series C, Series D and Series E Preferred Stock shall, when each such increase
or decrease becomes effective, be readjusted to reflect the increase or decrease
insofar as it affects rights of exercise or conversion which have not expired
before that time.

                    If on the expiration of such rights or options or the rights
of conversion of such convertible securities any of them shall not have been
exercised, the Conversion Price for the Series A, Series B, Series C, Series D
and Series E Preferred Stock shall be readjusted and shall thereafter be the
same as it would have been had it originally been adjusted (or had the original
adjustment not been required, as the case may be), on the basis that the only

                                      -9-
<PAGE>
 
shares of Additional Stock so issued were the shares of Additional Stock, if
any, actually issued or sold on the exercise of such rights or options or rights
of conversion of such convertible securities, and such shares of Additional
Stock, if any, were issued or sold for the consideration actually received by
the corporation on such exercise plus the consideration, if any, actually
received by the corporation for granting all such rights or options or for
issuing or selling all such convertible securities; provided that, no such
readjustment shall have the effect of increasing the Conversion Price of any
such series of Preferred Stock to the amount which exceeds the lower of: (i) the
Conversion Price for such series of Preferred Stock on the original adjustment
date with respect to such securities or (ii) the Conversion Price for such
series of Preferred Stock that would have resulted between the original
adjustment date with respect to such securities and such readjustment.

                    "Additional Stock" shall mean any shares of Common Stock
issued (or deemed to have been issued pursuant to this paragraph (b)(3)(ee)) by
this corporation after the Original Issue Date other than:

                    (1)   shares of Common Stock issued or issuable pursuant to
a transaction described in paragraph (b)(3)(dd) hereof;

                    (2)   up to 1,084,069 shares of Common Stock (or such
greater number as is unanimously approved by action of the Board of Directors,
which, if taken at a meeting, is taken at a meeting where all directors are
present) issued or issuable to employees, officers and directors of, and
consultants to, the corporation pursuant to any plan or arrangement approved by
the Board of Directors of the corporation;

                    (3)   shares of Common Stock issued or issuable upon
conversion of the Series A, Series B, Series C, Series D or Series E Preferred
Stock;

                    (4)   shares of Common Stock issued or issuable in
connection with the leasing or financing of equipment, approved by the Board of
Directors of the corporation;

                    (5)   shares of Series C Preferred Stock issued or issuable
upon exercise of the warrants granted pursuant to the Secured Note and Warrant
Purchase Agreement dated December 22, 1992, as amended, between the corporation
and the Purchasers (as defined therein);

                    (6)   shares of Common Stock issued or issuable upon
exercise of the warrants granted pursuant to the Note and Warrant Purchase
Agreement dated July 14, 1993, as amended, between the corporation and the
Purchasers (as defined therein);

                    (7)   shares of Series D Preferred Stock issued or issuable
upon exercise of warrants, as amended, originally issued to America Online, Inc.

Promissory Notes issued to Kleiner Perkins Caufield & Byers VII and KPCB VII
Founders Fund pursuant to the Secured Note Exchange Agreement dated as of
January 31, 1995;

                    (9)   297,619 shares of Common Stock issued or issuable to

                    (10)  shares of the corporation's capital stock issuable
upon conversion of the convertible promissory notes issued by the Company
pursuant to that certain Convertible Promissory Note Agreement, dated on or
about May 21, 1996, by and among the Company and the Purchasers (as defined
therein) (the "Note Agreement"); and

                    (11)  shares of Common Stock issuable upon exercise of the
warrants issued by the Company pursuant to the Note Agreement.

               (ff) Adjustments for Reorganizations, Reclassifications, etc. If
                    -------------------------------------------------------
the Common Stock issuable upon conversion of the Preferred Stock shall be
changed into the same or a different number of shares of any other class or
classes of stock or other securities or property, whether by reclassification or
a merger or consolidation of this corporation with or into any other corporation
or corporations in which the holders of the capital stock of this corporation
then hold 50% or more of the voting securities of the surviving corporation
(other than a transaction provided for elsewhere in this paragraph (b)(3) or in
paragraph (b)(4)(bb)), the Conversion Price for each series of Preferred Stock
then in effect shall, concurrently with the effectiveness of such reorganization
or reclassification, be adjusted such that each series of the Preferred Stock
shall be convertible into, in lieu of the number of shares of Common Stock which
the holders of Preferred Stock would otherwise have been entitled to receive, a
number of shares of such other class or classes of stock or securities or other
property equivalent to that which would have been subject to receipt by the
holders of the number of shares of Common Stock that would have been issuable
upon conversion of the Preferred Stock immediately before such event; and, in
any such case, appropriate adjustment (as determined by the Board of Directors)
shall be made in the application of the provisions herein set forth with respect
to the rights and interest thereafter of the holders of the Preferred Stock, to
the end that the provisions set forth herein (including provisions with respect
to changes in and other adjustments of the Conversion Price of any series of
Preferred Stock) shall thereafter be applicable, as nearly as may be reasonable,
in relation to any shares of stock or other property thereafter deliverable upon
the conversion of the Preferred Stock.

Certificate of Incorporation or through any reorganization, recapitalization,
transfer of assets, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the corporation, but

Stock against impairment.

               (hh) Certificate as to Adjustments.  Upon the occurrence of each
                    -----------------------------                              
adjustment or readjustment of the Conversion Rate and Conversion Price for
Series A, Series B, Series C, Series D or Series E Preferred Stock pursuant to
this paragraph (b)(3), the corporation at its expense shall promptly compute
such adjustment or readjustment in accordance with the terms hereof and prepare
and furnish to each holder of Series A, Series B, Series C, Series D and Series
E Preferred Stock a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based. The corporation shall, upon the written request at any time of any holder
of Series A, Series B, Series C, Series D or Series E Preferred Stock, furnish
or cause to be furnished to such holder a like certificate setting forth (i)
such adjustments and readjustments, (ii) the Conversion Rate and Conversion
Price for each series at the time in effect, and (iii) the number of shares of
Common Stock and the amount, if any, of other property which at the time would
be received upon the conversion of such holder's shares of Series A, Series B,
Series C, Series D and Series E Preferred Stock.

               (ii) Notices of Record Date. In the event of the establishment by
                    ----------------------

corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock solely for the purpose of effecting the
conversion of the shares of the Series A, Series B, Series C, Series D and
Series E Preferred Stock such number of its shares of Common Stock as shall from
time to time be sufficient to effect the conversion of all then outstanding
shares of the Series A, Series B, Series C, Series D and Series E Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock shall not be sufficient to effect the conversion of all then outstanding
shares of the Series A, Series B, Series C, Series D and Series E Preferred
Stock, the corporation will take such corporate action as may, in the opinion of
its counsel, be necessary to increase its authorized but unissued shares of
Common Stock to such number of shares as shall be sufficient for such purpose.

          (4)  Liquidation Preference.
               ---------------------- 

               (aa) In the event of any liquidation, dissolution or winding up
of the corporation, either voluntary or involuntary, the holders of the Series A
Preferred Stock shall be entitled to receive out of the assets of the
corporation available for distribution to its shareholders, prior and in
preference to any distribution of any of the assets or surplus funds of the
corporation to the holders of the Common Stock by reason of their ownership
thereof, the amount of $2.00 per share (as adjusted for stock dividends, stock
splits, recapitalizations and the like) for each share of Series A Preferred
Stock then held by them, and, in addition, an amount equal to all declared but
unpaid dividends on the Series A Preferred Stock, the holders of the Series B
Preferred Stock shall be entitled to receive out of the assets of the
corporation available for distribution to its shareholders, prior and in
preference to any distribution of any of the assets or surplus funds of the
corporation to the holders of the Common Stock by reason of their ownership
thereof, the amount of $2.00 per share (as adjusted for stock dividends, stock
splits, recapitalizations and the like) for each share of Series B Preferred
Stock then held by them, and, in addition, an amount equal to all declared but
unpaid dividends on the Series B Preferred Stock, the holders of the Series C
Preferred Stock shall be entitled to receive out of the assets of the
corporation available for distribution to its shareholders, prior and in
preference to any distribution of any of the assets or surplus funds of the
corporation to the holders of the Common Stock by reason of their ownership
thereof, the amount of $2.80 per share (as adjusted for stock dividends, stock
splits, recapitalizations and the like) for each share of Series C Preferred

unpaid dividends on the Series C Preferred Stock, the holders of the Series D
Preferred Stock shall be entitled to receive out of the assets of the

splits, recapitalizations and the like) for each share of Series E Preferred

shareholders shall be insufficient to permit the payment to the holders of the
Series A, Series B, Series C, Series D and Series E Preferred Stock of the full
preferential amount for the Series A, Series B, Series C, Series D and Series E
Preferred Stock, then the entire assets and funds of the corporation legally
available for distribution shall be distributed ratably among the holders of the

<PAGE>
 
Series A, Series B, Series C, Series D and Series E Preferred Stock (so that
each holder receives the same percentage of the applicable preferential amount).
After payment has been made to the holders of the Series A, Series B, Series C,
Series D and Series E Preferred Stock of the full amounts to which they shall be
entitled as aforesaid, the holders of shares of Common Stock shall be entitled
to receive the amount of $0.50 per share (as adjusted for stock dividends, stock
splits, recapitalizations and the like) for each share of Common Stock then held
by them, or if sufficient assets of the corporation available for distribution
to its shareholders are not available to make such payments in full, then a pro
rata amount based on the number of shares of Common Stock then held. Any
remaining assets of the corporation available for distribution to its
shareholders shall be distributed ratably to the holders of the corporation's
capital stock on a pro rata basis based upon the number of shares of Common
Stock held by, or issuable upon conversion of any shares of any series of
Preferred Stock held by, such holders.

               (bb) For purposes of this paragraph (b)(4), (i) any acquisition
of the corporation by means of merger or other form of corporate reorganization
in which outstanding shares of the corporation are exchanged for securities or
other consideration issued, or caused to be issued, by the acquiring corporation
or its subsidiary (other than a mere reincorporation transaction), (ii) any
transaction or series of transactions within any three-month period pursuant to
an agreement to which the corporation is a party (other than a registered public
offering pursuant to which the Series A, Series B, Series C, Series D and Series
E Preferred Stock is automatically converted into Common Stock pursuant to
paragraph (b)(3)(aa)(ii) above) in which greater than fifty percent (50%) of the
corporation's voting securities (on an as-converted-to-Common Stock basis) shall
be transferred, or (iii) a sale of all or substantially all of the assets of the
corporation, shall be treated as a liquidation, dissolution or winding up of the
corporation and shall entitle the holders of Series A, Series B, Series C,
Series D and Series E Preferred Stock to receive at the closing in cash or
securities (valued as provided in paragraph (b)(4)(cc) below) amounts as
specified in paragraph (b) (4)(aa) above.

               (cc) Whenever the distribution provided for in this paragraph
(b)(4) shall be payable in property other than cash, the value of such
distribution shall be the fair market value of such property as determined in
good faith by the Board of Directors.

               (dd) Each holder of an outstanding share of Series A, Series B,
Series C, Series D or Series E Preferred Stock shall be deemed to have consented
to distributions made by the corporation in connection with the repurchase of
shares of Common Stock issued to or held by officers, directors, employees or
consultants upon termination of their employment or services pursuant to
agreements providing for the right of said repurchase between the corporation
and such persons.

stockholders for monetary damages for breach of fiduciary duty as a director.
If the General Corporation Law of Delaware is hereafter amended to authorize,
with the approval of a corporation's stockholders, further reductions in the
liability of the Corporation's directors for breach of fiduciary duty, then a
director of the Corporation shall not be liable for any such breach to the
fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

     A.   To the fullest extent permitted by applicable law, the Corporation is

     B.   Any repeal or modification of any of the foregoing provisions of this
Article XII shall not adversely affect any right or protection of a director,
officer, agent or other person existing at the time of, or increase the
liability of any director of the Corporation with respect to any acts or
omissions of such director, officer or agent occurring prior to such repeal or
modification."

of the request. If the notice is not given within twenty (20) days after the

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

          All notices of meetings of stockholders shall be in writing and shall

not less than ten (10) nor more than sixty (60) days before the date of the
meeting to each stockholder entitled to vote at such meeting (or such longer or
shorter time as is required by Section 2.5 of these Bylaws, if applicable).  The

of a special meeting, the purpose or purposes for which the meeting is called.

          Written notice of any meeting of stockholders, if mailed, is given
when deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation.  An
affidavit of the secretary or an assistant secretary or of the transfer agent of
the corporation that the notice has been given shall, in the absence of fraud,
be prima facie evidence of the facts stated therein.

     2.5  ADVANCE NOTICE OF STOCKHOLDER NOMINEES.
          -------------------------------------- 

          Only persons who are nominated in accordance with the procedures set
forth in this Section 2.5 shall be eligible for election as directors.
Nominations of persons for election to the board of directors of the corporation
may be made at a meeting of stockholders by or at the direction of the board of
directors or by any stockholder of the corporation entitled to vote for the
election of directors at the meeting who complies with the notice procedures set
forth in this Section 2.5.  Such nominations, other than those made by or at the
direction of the board of directors, shall be made pursuant to timely notice in
writing to the secretary of the corporation.  
<PAGE>
 
To be timely, a stockholder's notice shall be delivered to or mailed and
received at the principal executive offices of the corporation not less than
sixty (60) days nor more than ninety (90) days prior to the meeting; provided,
however, that in the event that less than sixty (60) days' notice or prior
public disclosure of the date of the meeting is given or made to stockholders,
notice by the stockholder to be timely must be so received not later than the
close of business on the 10th day following the day on which such notice of the
date of the meeting was mailed or such public disclosure was made. Such
stockholder's notice shall set forth (a) as to each person whom the stockholder
proposes to nominate for election or re-election as a Director, (i) the name,
age, business address and residence address of such person, (ii) the principal
occupation or employment of such person, (iii) the class and number of shares of
the corporation which are beneficially owned by such person and (iv) any other
information relating to such person that is required to be disclosed in
solicitations of proxies for election of Directors, or is otherwise required, in
each case pursuant to Regulation 14A under the Securities Exchange Act of 1934,
as amended (including, without limitation, such person's written consent to
being named in the proxy statement as a nominee and to serving as a director if
elected); and (b) as to the stockholder giving the notice (i) the name and
address, as they appear on the corporation's books, of such stockholder and (ii)
the class and number of shares of the corporation which are beneficially owned
by such stockholder. At the request of the Board of Directors any person
nominated by the Board of Directors for election as a director shall furnish to
the secretary of the corporation that information required to be set forth in a
stockholder's notice of nomination which pertains to the nominee. No person
shall be eligible for election as a director of the corporation unless nominated
in accordance with the procedures set forth in this Section 2.5. The Chairman of
the meeting shall, if the facts warrant, determine and declare to the meeting
that a nomination was not made in accordance with the procedures prescribed by
the Bylaws, and if he or she should so determine, he or she shall so declare to
the meeting and the defective nomination shall be disregarded.

     2.6  QUORUM.
          ------ 

     The holders of a majority of the stock issued and outstanding and entitled
to vote thereat, present in person or represented by proxy, shall constitute a
quorum at all meetings of the stockholders for the transaction of business
except as otherwise provided by statute or by the certificate of incorporation.
If, however, such quorum is not present or represented at any meeting of the
stockholders, then either (a) the chairman of the meeting or (b) the
stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum is present or
represented.  At such adjourned meeting at which a quorum is present or
represented, any business may be transacted that might have been transacted at
the meeting as originally noticed.

     2.7  ADJOURNED MEETING; NOTICE.
          ------------------------- 

          When a meeting is adjourned to another time or place, unless these
Bylaws otherwise require, notice need not be given of the adjourned meeting if
the time and place thereof are announced at the meeting at which the adjournment
is taken.  At the adjourned meeting the 

                                      -3-
<PAGE>
 
corporation may transact any business that might have been transacted at the
original meeting. If the adjournment is for more than thirty (30) days, or if
after the adjournment a new record date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given to each stockholder of record
entitled to vote at the meeting.

     2.8  CONDUCT OF BUSINESS.
          -------------------

of business and the procedure at the meeting, including the manner of voting and
the conduct of business.

shall be determined in accordance with the provisions of Section 2.11 of these
Bylaws, subject to the provisions of Sections 217 and 218 of the General
Corporation Law of Delaware (relating to voting rights of fiduciaries, pledgors
and joint owners of stock and to voting trusts and other voting agreements).

          (b) Except as may be otherwise provided in the certificate of
incorporation, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder.

     2.10 WAIVER OF NOTICE.
          ---------------- 

          Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice.  Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened.  Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these Bylaws.

     2.11 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING.

change, conversion or exchange of stock or for the purpose of any other lawful
action, the Board of Directors may fix, in advance, a record date, which shall
not be more than sixty (60) nor less than ten (10) days before the date of such
meeting, nor more than sixty (60) days prior to any other action. If the Board
of Directors does not so fix a record date:

<PAGE>
 
          (a) The record date for determining stockholders entitled to notice of
or to vote at a meeting of stockholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which the meeting is
held.

          (b) The record date for determining stockholders for any other purpose
shall be at the close of business on the day on which the Board of Directors
adopts the resolution relating thereto.

          A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

     2.12 PROXIES.
          ------- 

          Each stockholder entitled to vote at a meeting of stockholders may
authorize another person or persons to act for such stockholder by a written
proxy, signed by the stockholder and filed with the secretary of the
corporation, but no such proxy shall be voted or acted upon after three (3)
years from its date, unless the proxy provides for a longer period.  A proxy
shall be deemed signed if the stockholder's name is placed on the proxy (whether
by manual signature, typewriting, telegraphic transmission or otherwise) by the
stockholder or the stockholder's attorney-in-fact.  The revocability of a proxy
that states on its face that it is irrevocable shall be governed by the
provisions of Section 212(e) of the General Corporation Law of Delaware.

                                  ARTICLE III

     3.1  POWERS.
          ------

constituting the entire Board of Directors shall be nine (9).  Thereafter, this

before such director's term of office expires.

                                      -5-
<PAGE>
 
     3.3  ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS.
          ------------------------------------------------------- 

          Except as provided in Section 3.4 of these Bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting.  Directors need not be stockholders unless so required by the
certificate of incorporation or these Bylaws, wherein other qualifications for
directors may be prescribed. Each director, including a director elected to fill
a vacancy, shall hold office until his or her successor is elected and qualified
or until his or her earlier resignation or removal.

          Elections of directors need not be by written ballot.

     3.4  RESIGNATION AND VACANCIES.
          ------------------------- 

          Any director may resign at any time upon written notice to the
attention of the Secretary of the corporation.  When one or more directors so
resigns and the resignation is effective at a future date, a majority of the
directors then in office, including those who have so resigned, shall have power
to fill such vacancy or vacancies, the vote thereon to take effect when such
resignation or resignations shall become effective, and each director so chosen
shall hold office as provided in this section in the filling of other vacancies.
A vacancy created by the removal of a director by the vote of the stockholders
or by court order may be filled only by the affirmative vote of a majority of
the shares represented and voting at a duly held meeting at which a quorum is
present (which shares voting affirmatively also constitute a majority of the
quorum.  Each director so elected shall hold office until the next annual
meeting of the stockholders and until a successor has been elected and
qualified.

          Unless otherwise provided in the certificate of incorporation or these
Bylaws:

          (a) Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

          (b) Whenever the holders of any class or classes of stock or series
thereof are entitled to elect one or more directors by the provisions of the
certificate of incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the directors elected
by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

          If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these Bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

                                      -6-
<PAGE>
 
          If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the whole board (as constituted immediately prior to any such increase), then
the Court of Chancery may, upon application of any stockholder or stockholders
holding at least ten (10) percent of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office as aforesaid,
which election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

     3.5  PLACE OF MEETINGS; MEETINGS BY TELEPHONE.
          ---------------------------------------- 

          The Board of Directors of the corporation may hold meetings, both
regular and special, either within or outside the State of Delaware.

          Unless otherwise restricted by the certificate of incorporation or
these Bylaws, members of the Board of Directors, or any committee designated by
the Board of Directors, may participate in a meeting of the Board of Directors,
or any committee, by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and such participation in a meeting shall constitute presence in

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

          Regular meetings of the Board of Directors may be held without notice
at such time and at such place as shall from time to time be determined by the

may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two directors.

          Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation.  If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting.  If the notice is delivered personally or by
telephone or by telegram, it shall be delivered personally or by telephone or to
the telegraph company at least forty-eight (48) hours before the time of the
holding of the meeting.  Any oral notice given personally or by telephone may be
communicated either to the director or to a person at the office of the director

it to the director.  The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
corporation.

                                      -7-
<PAGE>
 
     3.8  QUORUM.
          ------ 

          At all meetings of the Board of Directors, a majority of the
authorized number of directors shall constitute a quorum for the transaction of
business and the act of a majority of the directors present at any meeting at
which there is a quorum shall be the act of the Board of Directors, except as
may be otherwise specifically provided by statute or by the certificate of
incorporation.  If a quorum is not present at any meeting of the Board of
Directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

          A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

     3.9  WAIVER OF NOTICE.
          ---------------- 

          Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice.  Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened.  Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the directors, or members of a committee of directors, need be specified in
any written waiver of notice unless so required by the certificate of
incorporation or these Bylaws.

     3.10 BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING.
          ------------------------------------------------- 

          Unless otherwise restricted by the certificate of incorporation or
these Bylaws, any action required or permitted to be taken at any meeting of the
Board of Directors, or of any committee thereof, may be taken without a meeting
if all members of the board or committee, as the case may be, consent thereto in
writing and the writing or writings are filed with the minutes of proceedings of
the board or committee.  Written consents representing actions taken by the
board or committee may be executed by telex, telecopy or other facsimile
transmission, and such facsimile shall be valid and binding to the same extent
as if it were an original.

     3.11 FEES AND COMPENSATION OF DIRECTORS.
          ---------------------------------- 

          Unless otherwise restricted by the certificate of incorporation or
these Bylaws, the Board of Directors shall have the authority to fix the
compensation of directors.  No such compensation shall preclude any director
from serving the corporation in any other capacity and receiving compensation
therefor.

          The corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the corporation or of its
subsidiary, including any officer or employee who is a director of the
corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
corporation.  The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the Board of
Directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation.  Nothing in this section contained shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

     3.13 REMOVAL OF DIRECTORS.
          -------------------- 

          Unless otherwise restricted by statute, by the certificate of
incorporation or by these Bylaws, any director or the entire Board of Directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors; provided, however,
that if the stockholders of the corporation are entitled to cumulative voting,
if less than the entire Board of Directors is to be removed, no director may be
removed without cause if the votes cast against his removal would be sufficient
to elect him if then cumulatively voted at an election of the entire Board of
Directors.

          No reduction of the authorized number of directors shall have the
effect of removing any director prior to the expiration of such director's term
of office.

     3.14 CHAIRMAN OF THE BOARD OF DIRECTORS.
          ---------------------------------- 

          The corporation may also have, at the discretion of the Board of
Directors, a chairman of the Board of Directors who shall not be considered an
officer of the corporation.

disqualification of a member of a committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not such
member or members constitute a quorum, may unanimously appoint another member of
the Board of Directors to act at the meeting in the place of any such absent or
disqualified member.  Any such committee, to the extent provided in the
resolution of the Board of Directors or in the Bylaws of the corporation, shall
have and may exercise all the powers and authority of the Board

of Directors in the management of the business and affairs of the corporation,
and may authorize the seal of the corporation to be affixed to all papers that

amend the certificate of incorporation (except that a committee may, to the
extent authorized in the resolution or resolutions providing for the issuance of
shares of stock adopted by the Board of Directors as provided in Section 151(a)
of the General Corporation Law of Delaware, fix the designations and any of the
preferences or rights of such shares relating to dividends, redemption,
dissolution, any distribution of assets of the corporation or the conversion
into, or the exchange of such shares for, shares of any other class or classes
or any other series of the same or any other class or classes of stock of the

resolution establishing the committee, the Bylaws or the certificate of
incorporation expressly so provide, no such committee shall have the power or
authority to declare a dividend, to authorize the issuance of stock, or to adopt
a certificate of ownership and merger pursuant to Section 253 of the General
Corporation Law of Delaware.

meetings by telephone), Section 3.6 (regular meetings), Section 3.7 (special
meetings and notice), Section 3.8 (quorum), Section 3.9 (waiver of notice), and
Section 3.10 (action without a meeting) of these Bylaws, with such changes in
the context of such provisions as are necessary to substitute the committee and
its members for the Board of Directors and its members; provided, however, that
the time of regular meetings of committees may be determined either by
resolution of the Board of Directors or by resolution of the committee, that
special meetings of committees may also be called by resolution of the Board of
Directors and that notice of special meetings of committees shall also be given
to all alternate members, who shall have the right to attend all meetings of the
committee.  The Board of Directors may adopt rules for the government of any

directors and officers against expenses (including attorneys' fees), judgments,
fines, settlements and other amounts actually and reasonably incurred in

a director or officer of the corporation, (b) who is or was serving at the
request of the corporation as a director or officer of another corporation,

manner permitted by the General Corporation Law of Delaware, to indemnify each
of its employees and agents (other than directors and officers) against expenses
(including attorneys' fees), judgments, fines, settlements and other amounts
actually and reasonably incurred in connection with any proceeding, arising by

than a director or officer) includes any person (a) who is or was an employee or
agent of the corporation, (b) who is or was serving at the request of the
corporation as an employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, or (c) who was an employee or agent of a

     6.3  PAYMENT OF EXPENSES IN ADVANCE.
          ------------------------------ 

          Expenses incurred in defending any action or proceeding for which

Board of Directors shall be paid by the corporation in advance of the final
disposition of such action or proceeding upon receipt of an undertaking by or on
behalf of the indemnified party to repay such amount if it shall ultimately

                                     -14-
<PAGE>
 
be determined that the indemnified party is not entitled to be indemnified as
authorized in this Article VI.

     6.4  INDEMNITY NOT EXCLUSIVE.
          ----------------------- 

          The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any Bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the certificate of
incorporation

     6.5  INSURANCE.
          --------- 

          The corporation may purchase and maintain insurance on behalf of any

employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,
whether or not the corporation would have the power to indemnify him or her
against such liability under the provisions of the General Corporation Law of
Delaware.

     6.6  CONFLICTS.
          --------- 

          No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

          (a) That it would be inconsistent with a provision of the certificate
of incorporation, these Bylaws, a resolution of the stockholders or an agreement
in effect at the time of the accrual of the alleged cause of the action asserted
in the proceeding in which the expenses were incurred or other amounts were
paid, which prohibits or otherwise limits indemnification; or

          (b) That it would be inconsistent with any condition expressly imposed
by a court in approving a settlement.

right during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom.  A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder.  In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder.  The demand under oath shall be directed to the
corporation at its registered office in Delaware or at its principal place of
business.

     7.2  INSPECTION BY DIRECTORS.
          ----------------------- 

          Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his or her position as a director.  The Court of
Chancery is hereby vested with the exclusive jurisdiction to determine whether a
director is entitled to the inspection sought.  The Court may summarily order
the corporation to permit the director to inspect any and all books and records,
the stock ledger, and the stock list and to make copies or extracts therefrom.
The Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the Board of Directors or within the agency
power of an officer, no officer, agent or employee shall have any power or

                                     -16-

authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

     8.3  STOCK CERTIFICATES; PARTLY PAID SHARES.
          -------------------------------------- 

          The shares of a corporation shall be represented by certificates,
provided that the Board of Directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares.  Any such resolution shall not apply
to shares represented by a certificate until such certificate is surrendered to
the corporation.  Notwithstanding the adoption of such a resolution by the Board
of Directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the corporation by the chairman or vice-chairman of
the Board of Directors, or the chief executive officer or the president or vice-
president, and by the chief financial officer or an assistant treasurer, or the
secretary or an assistant secretary of such corporation representing the number
of shares registered in certificate form.  Any or all of the signatures on the
certificate may be a facsimile.  In case any officer, transfer agent or
registrar who has signed or whose facsimile signature has been placed upon a
certificate has ceased to be such officer, transfer agent or registrar before
such certificate is issued, it may be issued by the corporation with the same
effect as if he or she were such officer, transfer agent or registrar at the
date of issue.

          The corporation may issue the whole or any part of its shares as
partly paid and subject to call for the remainder of the consideration to be
paid therefor.  Upon the face or back of each stock certificate issued to
represent any such partly paid shares, upon the books and records of the
corporation in the case of uncertificated partly paid shares, the total amount
of the consideration to be paid therefor and the amount paid thereon shall be
stated.  Upon the declaration of any dividend on fully paid shares, the
corporation shall declare a dividend upon partly paid shares of the same class,
but only upon the basis of the percentage of the consideration actually paid
thereon.

     8.4  SPECIAL DESIGNATION ON CERTIFICATES.
          ----------------------------------- 

          If the corporation is authorized to issue more than one class of stock
or more than one series of any class, then the powers, the designations, the
preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences, and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

          Except as provided in this Section 8.5, no new certificates for shares

surrendered to the corporation and canceled at the same time.  The corporation
may issue a new certificate of stock or uncertificated shares in the place of

          The Bylaws of the corporation may be adopted, amended or repealed by
the stockholders entitled to vote; provided, however, that the corporation may,
in its certificate of incorporation, confer the power to adopt, amend or repeal
Bylaws upon the directors.  The fact that such power has been so conferred upon
the directors shall not divest the stockholders of the power, nor limit their
power to adopt, amend or repeal Bylaws.

Delaware, as the same may be amended from time to time, a director of the

stockholders for monetary damages for breach of fiduciary duty as a director.
If the General Corporation Law of Delaware is hereafter amended to authorize,
with the approval of a corporation's stockholders, further reductions in the
liability of the Corporation's directors for breach of fiduciary duty, then a
director of the Corporation shall not be liable for any such breach to the
fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

     (B)  Any repeal or modification of the foregoing provisions of this Article
XIII shall not adversely affect any right or protection of a director of the
Corporation with respect to any acts or omissions of such director occurring
prior to such repeal or modification.

Article XIV shall not adversely affect any right or protection of a director,
officer, agent or other person existing at the time of, or increase the
liability of any director of the Corporation with respect to any acts or
omissions of such director, officer or agent occurring prior to such repeal or
modification."

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

                                      -2-
<PAGE>
 
     (a)  Procedure. The Plan shall be administered by the Board of Directors of
          ---------                                                 
the Company.
 
          (i)   Subject to subparagraph (ii), the Board of Directors may appoint
a Committee consisting of not less than two members of the Board of Directors to
administer the Plan on behalf of the Board of Directors, subject to such terms
and conditions as the Board of Directors may prescribe. Once appointed, the
Committee shall continue to serve until otherwise directed by the Board of
Directors. Members of the Board who are either eligible for Options or have been
granted Options may vote on any matters affecting the administration of the Plan
or the grant of any Options pursuant to the Plan, except that no such member
shall act upon the granting of an Option to himself, but any such member may be
counted in determining the existence of a quorum at any meeting of the Board
during which action is taken with respect to the granting of Options to him.

          (ii)  Notwithstanding the foregoing subparagraph (i), if and in any
event the Company registers any class of any equity security pursuant to Section
12 of the Exchange Act, from the effective date of such registration until six
months after the termination of such registration, any grants of Options to
officers or directors shall only be made by the Board of Directors; provided,
however, that if a majority of the Board of Directors is eligible to participate
in this Plan or any other stock option or other stock plan of the Company or any
of its affiliates, or has been eligible at any time within the preceding year or
(if shorter) during the period following the initial registration of the
Company's equity securities pursuant to Section 12 of the Exchange Act, any
grants of options to directors must be made by, or only in accordance with the
recommendation of, a Committee consisting of three or more persons, who may but
need not be directors or employees of the Company, appointed by the Board of
Directors and having full authority to act in the matter, none of whom is
eligible to participate in this Plan or any other stock option or other stock
plan of the Company or any of its affiliates or has been eligible at any time
within the preceding year or (if shorter) during the period following the
initial registration of the Company's equity securities pursuant to Section 12
of the Exchange Act.  Any Committee administering the Plan with respect to
grants to officers who are not also directors shall conform to the requirements
of the preceding sentence.  Once appointed, the Committee shall continue to
serve until otherwise directed by the Board of Directors.

          (iii) Subject to the foregoing subparagraphs (i) and (ii), from time
to time the Board of Directors may increase the size of the Committee and
appoint additional members thereof, remove members (with or without cause) and
appoint new members in substitution therefor, fill vacancies however caused, or
remove all members of the Committee and thereafter directly administer the Plan.

     (b)  Powers of the Board.  Subject to the provisions of the Plan, the
          -------------------                                             
Board shall have the authority, in its discretion:  (i) to grant Incentive Stock
Options or Nonstatutory Stock Options; (ii) to determine, upon review of
relevant information and in accordance with Section 8(b) of the Plan, the fair
market value of the Common Stock; (iii) to determine the exercise price per
share of Options to be granted, which exercise price shall be determined in
accordance with Section 8(a) of the Plan; (iv) to determine the Employees or
Consultants to 

                                      -3-
<PAGE>
 
whom, and the time or times at which, Options shall be granted and the number of
shares to be represented by each Option; (v) to interpret the Plan; (vi) to
prescribe, amend and rescind rules and regulations relating to the Plan; (vii)
to determine the terms and provisions of each Option granted (which need not be
identical) and, with the consent of the holder thereof, modify or amend each
Option; (viii) to accelerate or defer (with the consent of the Optionee) the
exercise date of any Option, consistent with the provisions of Section 5 of the
Plan; (ix) to authorize any person to execute on behalf of the Company any
instrument required to effectuate the grant of an Option previously granted by
the Board; and (x) to make all other determinations deemed necessary or
advisable for the administration of the Plan.

          (c) Effect of Board's Decision.  All decisions, determinations and
              --------------------------                                    
interpretations of the Board shall be final and binding on all Optionees and any
other holders of any Options granted under the Plan.

     5.   Eligibility.
          ----------- 

          (a) Nonstatutory Stock Options may be granted only to Employees and
Consultants.  Incentive Stock Options may be granted only to Employees.  An
Employee or Consultant who has been granted an Option may, if he is otherwise
eligible, be granted an additional Option or Options.

          (b) No Incentive Stock Option may be granted to an Employee which,
when aggregated with all other incentive stock options granted to such Employee
by the Company or any Parent or Subsidiary, would result in Shares having an
aggregate fair market value (determined for each Share as of the date of grant
of the Option covering such Share) in excess of $100,000 becoming first
available for purchase upon exercise of one or more incentive stock options
during any calendar year.

          (c) Section 5(b) of the Plan shall apply only to an Incentive Stock
Option evidenced by an "Incentive Stock Option Agreement" which sets forth the
intention of the Company and the Optionee that such Option shall qualify as an
incentive stock option.  Section 5(b) of the Plan shall not apply to any Option
evidenced by a "Nonstatutory Stock Option Agreement" which sets forth the
intention of the Company and the Optionee that such Option shall be a
Nonstatutory Stock Option.

          (d) The Plan shall not confer upon any Optionee any right with respect
to continuation of employment or consulting relationship with the Company, nor
shall it interfere in any way with his right or the Company's right to terminate
his employment or consulting relationship at any time, with or without cause.

     6.   Term of Plan.  The Plan shall become effective upon the earlier to
          ------------                                                      
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company as described in Section 17 of the Plan.  It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 13 of the Plan.

                                      -4-
<PAGE>
 
     7.   Term of Option.  The term of each Incentive Stock Option shall be ten
          --------------                                                       
(10) years from the date of grant thereof or such shorter term as may be
provided in the Incentive Stock Option Agreement.  The term of each Nonstatutory
Stock Option shall be ten (10) years and one (1) day from the date of grant
thereof or such shorter term as may be provided in the Nonstatutory Stock Option
Agreement.  However, in the case of an Option granted to an Optionee
who, at the time the Option is granted, owns stock representing more than ten
percent (10%) of the voting power of all classes of stock of the Company or any
Parent or Subsidiary, (a) if the Option is an Incentive Stock Option, the term
of the Option shall be five (5) years from the date of grant thereof or such
shorter term as may be provided in the Incentive Stock Option Agreement, or (b)
if the Option is a Nonstatutory Stock Option, the term of the Option shall be
five (5) years and one (1) day from the date of grant thereof or such shorter
term as may be provided in the Nonstatutory Stock Option Agreement.

     8.   Exercise Price and Consideration.
          -------------------------------- 

          (a)  The per Share exercise price for the Shares to be issued pursuant
to exercise of an Option shall be such price as is determined by the Board, but
shall be subject to the following:

                (i)  In the case of an Incentive Stock Option

                     (A) granted to an Employee who, at the time of the grant of
such Incentive Stock Option, owns stock representing more than ten percent (10%)
of the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 110% of the fair
market value per Share on the date of grant.

                     (B) granted to any Employee, the per Share exercise price
shall be no less than 100% of the fair market value per Share on the date of
grant.

                (ii) In the case of a Nonstatutory Stock Option

                     (A) granted to a person who, at the time of the grant of
such Option, owns stock representing more than ten percent (10%) of the voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
per Share exercise price shall be no less than 110% of the fair market value per
Share on the date of the grant.

                     (B) granted to any person, the per Share exercise price
shall be no less than 85% of the fair market value per Share on the date of
grant.

               (iii) In the case of an Option granted on or after the effective
date of registration of any class of equity security of the Company pursuant to
Section 12 of the Exchange Act and prior to six months after the termination of
such registration, the per Share exercise price shall be no less than 100% of
the fair market value per Share on the date of grant.

          (b)  The fair market value shall be determined by the Board in its
discretion; provided, however, that where there is a public market for the
Common Stock, the fair market 

                                      -5-
<PAGE>
 
value per Share shall be the mean of the bid and asked prices (or the closing
price per share if the Common Stock is listed on the National Association of
Securities Dealers Automated Quotation ("NASDAQ") National Market System) of the
Common Stock for the date of grant, as reported in the Wall Street Journal (or,
if not so reported, as otherwise reported by the NASDAQ System) or, in the event
the Common Stock is listed on a stock exchange, the fair market value per Share
shall be the closing price on such exchange on the date of grant of the Option,
as reported in the Wall Street Journal.

          (c) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Board and may consist entirely of cash, check, promissory note, other Shares
of Common Stock having a fair market value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised, or any combination of such methods of payment, or such other
consideration and method of payment for the issuance of Shares to the extent
permitted under Sections 408 and 409 of the California General Corporation Law.
In making its determination as to the type of consideration to accept, the Board
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company (Section 315(b) of the California General Corporation Law).

     9.   Exercise of Option.
          ------------------ 

          (a)  Procedure for Exercise; Rights as a Shareholder.  Any Option
               -----------------------------------------------             
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Board, including performance criteria with respect to the
Company and/or the Optionee, and as shall be permissible under the terms of the
Plan; provided, however, that an Incentive Stock Option granted prior to January
1, 1987 (the "Sequential Option") shall not be exercisable while there is
outstanding any Incentive Stock Option which was granted, before the granting of
the Sequential Option, to the same Optionee to purchase stock of the Company,
any Parent or Subsidiary, or any predecessor corporation of such corporations.
For purposes of this provision, an Incentive Stock Option shall be treated as
outstanding until such option is exercised in full or expires by reason of lapse
of time.

               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may, as authorized by the Board, consist of any
consideration and method of payment allowable under Section 8(c) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. No

                                      -6-
<PAGE>
 
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

               Exercise of an Option in any manner shall result in a decrease in
the number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

          (b)  Termination of Status as an Employee or Consultant.  In the event
               --------------------------------------------------               
of termination of an Optionee's Continuous Status as an Employee or Consultant
(as the case may be), such Optionee may, but only within thirty (30) days (or
such other period of time, not exceeding three (3) months in the case of an
Incentive Stock Option or six (6) months in the case of a Nonstatutory Stock
Option, as is determined by the Board, with such determination in the case of an
Incentive Stock Option being made at the time of grant of the Option) after the
date of such termination (but in no event later than the date of expiration of
the term of such Option as set forth in the Option Agreement), exercise his
Option to the extent that he was entitled to exercise it at the date of such
termination.  To the extent that he was not entitled to exercise the Option at
the date of such termination, or if he does not exercise such Option (which he
was entitled to exercise) within the time specified herein, the Option shall
terminate.

          (c)  Disability of Optionee. Notwithstanding the provisions of section
               ----------------------
9(b) above, in the event of termination of an Optionee's Continuous Status as an
Employee or Consultant as a result of his disability, he may, but only within
six (6) months (or such other period of time not exceeding twelve (12) months as
is determined by the Board, with such determination in the case of an Incentive
Stock Option being made at the time of grant of the Option) from the date of
such termination (but in no event later than the date of expiration of the term
of such Option as set forth in the Option Agreement), exercise his Option to the
extent he was entitled to exercise it at the date of such termination. To the
extent that he was not entitled to exercise the Option at the date of
termination, or if he does not exercise such Option (which he was entitled to
exercise) within the time specified herein, the Option shall terminate.

          (d)  Death of Optionee.  In the event of the death of an Optionee:
               -----------------                                            

               (i)  during the term of the Option who is at the time of his
death an Employee or Consultant of the Company and who shall have been in
Continuous Status as an Employee or Consultant since the date of grant of the
Option, the Option may be exercised, at any time within six (6) months following
the date of death (but in no event later than the date of expiration of the term
of such Option as set forth in the Option Agreement), by the Optionee's estate
or by a person who acquired the right to exercise the Option by bequest or
inheritance, but only to the extent of the right to exercise that would have
accrued had the Optionee continued living and remained in Continuous Status as
an Employee or Consultant six (6) months after the date of death, subject to the
limitation set forth in Section 5(b); or

               (ii) within thirty (30) days (or such other period of time not
exceeding three (3) months as is determined by the Board, with such
determination in the case of an Incentive Stock Option being made at the time of
grant of the Option) after the termination of Con

                                      -7-
<PAGE>
 
tinuous Status as an Employee or Consultant, the Option may be exercised, at any
time within six (6) months following the date of death (but in no event later
than the date of expiration of the term of such Option as set forth in the
Option Agreement), by the Optionee's estate or by a person who acquired the
right to exercise the Option by bequest or inheritance, but only to the extent
of the right to exercise that had accrued at the date of termination.

     10.  Non-Transferability of Options.  The Option may not be sold, pledged,
          ------------------------------                                       
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

     11.  Adjustments Upon Changes in Capitalization or Merger.  Subject to any
          ----------------------------------------------------                 
required action by the shareholders of the Company, the number of shares of
Common Stock covered by each outstanding Option, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options have yet been granted or which have been returned to the Plan
upon cancellation or expiration of an Option, as well as the price per share of
Common Stock covered by each such outstanding Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

          In the event of the proposed dissolution or liquidation of the
Company, the Board shall notify the Optionee at least fifteen (15) days prior to
such proposed action.  To the extent it has not been previously exercised, the
Option will terminate immediately prior to the consummation of such proposed
action.  In the event of a merger of the Company with or into another
corporation, the Option shall be assumed or an equivalent option shall be
substituted by such successor corporation (or a parent or subsidiary of such
successor corporation).  In the event that such successor corporation refuses to
assume the Option or to substitute an equivalent option, the Board shall, in
lieu of such assumption or substitution, provide for the Optionee to have the
right to exercise the Option as to all of the Optioned Stock, including Shares
as to which the Option would not otherwise be exercisable.  If the Board makes
an Option fully exercisable in lieu of assumption or substitution in the event
of a merger, the Board shall notify the Optionee that the Option shall be fully
exercisable for a period of thirty (30) days from the date of such notice, and
the Option will terminate upon the expiration of such period.

     12.  Time of Granting Options.  The date of grant of an Option shall, for
          ------------------------                                            
all purposes, be the date on which the Board makes the determination granting
such Option.  Notice of the 

                                      -8-
<PAGE>
 
determination shall be given to each Employee or Consultant to whom an Option is
so granted within a reasonable time after the date of such grant.

     13.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a) Amendment and Termination.  The Board may amend or terminate the
              -------------------------                                       
Plan from time to time in such respects as the Board may deem advisable;
provided that, the following revisions or amendments shall require approval of
the shareholders of the Company in the manner described in Section 17 of the
Plan:

               (i)   any increase in the number of Shares subject to the Plan,
other than in connection with an adjustment under Section 11 of the Plan;

               (ii)  any change in the designation of the class of persons
eligible to be granted Options; or

               (iii) if the Company has a class of equity securities registered
under Section 12 of the Exchange Act at the time of such revision or amendment,
any material increase in the benefits accruing to participants under the Plan.

          (b)  Shareholder Approval.  If any amendment requiring shareholder
               --------------------                                         
approval under Section 13(a) of the Plan is made subsequent to the first
registration of any class of equity securities by the Company under Section 12
of the Exchange Act, such shareholder approval shall be solicited as described
in Section 17 of the Plan.

          (c)  Effect of Amendment or Termination.  Any such amendment or
               ----------------------------------                        
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

     14.  Conditions Upon Issuance of Shares.  Shares shall not be issued
          ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

          As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

                                      -9-
<PAGE>
 
     15.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------                                             
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

          The inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company's counsel to
be necessary to the lawful issuance and sale of any Shares hereunder, shall
relieve the Company of any liability in respect of the failure to issue or sell
such Shares as to which such requisite authority shall not have been obtained.

     16.  Option Agreement.  Options shall be evidenced by written option
          ----------------                                               
agreements in such form as the Board shall approve.

     17.  Shareholder Approval.
          -------------------- 

          (a) Continuance of the Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months before or after the date
the Plan is adopted.  If such shareholder approval is obtained at a duly held
shareholders' meeting, it must be obtained by the affirmative vote of the
holders of a majority of the outstanding shares of the Company, or if such
shareholder approval is obtained by written consent, it must be obtained by the
unanimous written consent of all shareholders of the Company; provided, however,
that approval at a meeting or by written consent may be obtained by a lesser
degree of shareholder approval if the Board determines, in its discretion after
consultation with the Company's legal counsel, that such a lesser degree of
shareholder approval will comply with all applicable laws and will not adversely
affect the qualification of the Plan under Section 422A of the Code.

          (b) If and in the event that the Company registers any class of equity
securities pursuant to Section 12 of the Exchange Act, any required approval of
the shareholders of the Company obtained after such registration shall be
solicited substantially in accordance with Section 14(a) of the Exchange Act and
the rules and regulations promulgated thereunder.

          (c) If any required approval by the shareholders of the Plan itself or
of any amendment thereto is solicited at any time otherwise than in the manner
described in Section 17(b) hereof, then the Company shall, at or prior to the
first annual meeting of shareholders held subsequent to the later of (1) the
first registration of any class of equity securities of the Company under
Section 12 of the Exchange Act of (2) the granting of an Option hereunder to an
officer or director after such registration, do the following:

              (i) furnish in writing to the holders entitled to vote for the
Plan substantially the same information which would be required (if proxies to
be voted with respect to approval or disapproval of the Plan or amendment were
then being solicited) by the rules and regulations in effect under Section 14(a)
of the Exchange Act at the time such information is furnished; and

                                      -10-

               (ii) file with, or mail for filing to, the Securities and
Exchange Commission four copies of the written information referred to in
subsection (i) hereof not later than the date on which such information is first
sent or given to shareholders.

     18.  Information to Optionees.  The Company shall provide to each Optionee,
          ------------------------                                              
during the period for which such Optionee has one or more Options outstanding,
copies of all annual reports and other information.  The Company shall not be
required to provide such information if the issuance of Options under the Plan
is limited to key employees whose duties in connection with the Company assure
their access to equivalent information.

"Plan") adopted by the Company, which is incorporated herein by reference.
Unless otherwise defined herein, the terms defined in the Plan shall have the
same defined meanings herein.

<PAGE>

Shares in respect of which the Option is being exercised, and such other
representations and agreements as to the holder's investment intent with respect
to such shares of Common Stock as may be required by the Company pursuant to the
provisions of the Plan. Such written notice shall be signed by the Optionee and

Company. The written notice shall be accompanied by payment of the exercise
price. this Option shall be deemed exercised upon receipt by the Company of such

          ------------------------                                         
time as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of

federal or state securities or other law or regulation, including any rule under
Part 207 of title 12 of the Code of Federal Regulations ("Regulation G") as

termination (but in no event later that the date of expiration of the term of
this Option set forth in Section 11 below), exercise his Option to the extent he
was entitled to exercise it at the date of such termination.  To the extent that
he was not entitled to exercise the Option at the date of termination, or if he
does not exercise such Option (which he was entitled to exercise) within the
time specified herein, the Option shall terminate.

          9.   Death of Optionee.  In the event of the death of Optionee:
               -----------------                                         

               (i)  during the term of this Option and while an Employee of the
Company and having been in Continuous Status as an Employee since the date of

months following the date of death (but in no event later than the date of
expiration of the term of this Option as set forth in Section 11 below), by
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
would have accrued had Optionee continued living and remained in Continuous
Status as an Employee six (6) months after the date of death; or

               (ii) within three (3) months after the termination of Optionee's
Continuous Status as Employee, the Option may be exercised, at any time within
six (6) months following the date of death (but in no event later than the date
of expiration of the term of this Option as set forth in Section 11 below), by
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
had accrued at the date of termination.

          10.  Non-Transferability of Option.  This Option may not be
               -----------------------------                         
transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of Optionee only by him.
The terms of this Option shall be binding upon the executors, administrators,
heirs, successors and assigns of the Optionee.

          11.  Term of Option.  This Option may not be exercised more than five
               --------------                                                  
(5) years and one day from the date of grant of this Option, and may be
exercised during such term only in accordance with the Plan and the terms of
this Option.

          12.  Early Disposition of Stock.  Optionee understands that if he
               --------------------------                                  
disposes o any Shares received under this Option within two (2) years after the
date of this Agreement or within one (1) year after such Shares transferred to
him, he will be treated for federal income tax purposes as having received
ordinary income at the time of such disposition in an amount generally measured
by the difference between the price paid for the Shares and the lower of the
fair market value of the Shares at the date of the exercise or the fair market
value of the Shares at the date of disposition.  The amount of such ordinary
income may be measured differently if Optionee is an officer, director or 10%
shareholder of the Company, or if the Shares were subject to a substantial risk
of forfeiture at the time they were transferred to Optionee.  Optionee hereby
                                                              ---------------

that if he disposes of such Shares at any time after the expiration of such two-
year and one-year holding periods, any gain on such sale will be taxed as long-
term capital gain.

Optionee:      ______________________

Company:       Preview Travel, Inc.

Security:      Common Stock

Amount:        _______ Shares

In connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following:

               (a)  Optionee is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the securities. Optionee
is acquiring these securities for investment for Optionee's own account only and
nor with a view to, or for resale in connection with any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

               (b)  Optionee acknowledges and understands that the securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Optionee's investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities Exchange Commission,
the statutory basis for such exemption may be unavailable if Optionee's
representation was predicated solely upon a present intention to hold these
Securities for the minimum capital gains period specified under tax statures,
for a deferred sale, for or until an increase or decrease in the market price of
the Securities, or for a period of one year or any other fixed period in the
future. Optionee further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available. Optionee further acknowledges
and understands that the Company is under no obligation to register the
securities. Optionee understands that the certificate evidencing the securities
will be imprinted with a legend which prohibits the transfer of the Securities
unless they are registered or such registration is not required in the opinion
of counsel satisfactory to the Company, a legend prohibiting their transfer
without the consent of the Commissioner of Corporations of the State of
California and any other legend required under applicable state securities laws.

               (c)  Optionee is familiar with the provisions of Rule 701 and
Rule 144, each promulgated under the Securities Act, which, in substance, permit
limited public resale of "restricted securities" acquired, directly or
indirectly from the issuer thereof, in a nonpublic offering subject to the
satisfaction of certain conditions. Rule 701 provides that if the issuer
<PAGE>
 
qualifies under Rule 701 at the time of exercise of the Option by the Optionee,
such exercise will be exempt from registration under the Securities Act. In the
event the Company later becomes subject to the reporting requirements of Section
13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter
the securities exempt under Rule 701 may be resold, subject to the satisfaction
of certain of the conditions specified by Rule 144, including among other
things: (1) the sale being made through a broker in an unsolicited "broker's
transaction" or in transactions directly with a market maker (as said term is
defined under the Securities Exchange Act of 1934); and, in the case of an
affiliate, (2) the availability of certain public information about the Company,
and the amount of securities being sold during any three month period not
exceeding the limitations specified in Rule 144(e), if applicable.

          In the event that the Company does not qualify under Rule 701 at the
time of exercise of the Option, then the securities may be resold in certain
limited circumstances subject to the provisions of Rule 144, which requires
among other things: (1) the resale occurring not less than two years after the
party has purchased, and made full payment for, within the meaning of Rule 144,
the securities to be sold; and, in the case of an affiliate, or of a non-
affiliate who has held the securities less than three years, (2) the
availability of certain public information about the Company, (3) the sale being
made through a broker in any unsolicited "broker's transaction" or in
transactions directly with a market maker (as said term is defined under the
Securities Exchange Act of 1934), and (4) the amount of securities being sold
during any three month period not exceeding the specified limitations stated
therein, if applicable.

               (d)  Optionee agrees, in connection with the Company's initial
underwritten public offering of the Company's securities, (1) not to sell, make
short sale of, loan, grant any options for the purchase of, or otherwise dispose
of any shares of Common Stock of the Company held by Optionee (other than those
shares included in the registration) without prior written consent of the
Company or the underwriters managing such initial underwritten public offering
of the Company's securities for one hundred eighty (180) days from the effective
date of such registration, and (2) further agrees to execute any agreement
reflecting (1) above as may be requested by the underwriters at the time of the
public offering; provided however that the officers and directors of the Company
                 -------- -------                                               
who own the stock of the Company also agree to such restrictions.

               (e)  Optionee further understands that in the event all of the
applicable requirements of Rule 701 and 144 are not satisfied, registration
under the Securities Act, compliance with Regulation A, or some other
registration exemption will be required; and that, not-withstanding the fact
that Rules 144 and 701 are not exclusive, the Staff of the Securities and
Exchange Commission has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rules 144 or 701 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or
sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.  Optionee understands that no
assurances can be given that any such other registration exemption will be
available in such event.

               (f)  Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities without the consent of the Commissioner of Corporations of
California. Optionee has read the applicable Commissioner's Rules with respect
to such restriction, a copy of which is attached.

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

               (i)   MULTIPLE ADMINISTRATIVE BODIES. If permitted by Rule 16b-3,
                     ------------------------------

Named Executives as performance-based compensation under Section 162(m) of the
Code and otherwise so as to satisfy the Applicable Laws.

               (iii) ADMINISTRATION WITH RESPECT TO OTHER PERSONS. With respect

time to time the Board may increase the size of any Committee and appoint
additional members thereof, remove members (with or without cause) and appoint
new members in substitution therefor, fill vacancies (however caused) and remove
all members of a Committee and thereafter directly administer the Plan, all to
the extent permitted by the Applicable Laws and, in the case of a Committee

               ---------------------------                                   
Plan and in the case of a Committee, the specific duties delegated by the Board

acceleration or waiver of forfeiture restrictions regarding any Option and/or
the shares of Common Stock relating thereto, based in each case on such factors

               (vii) to reduce the exercise price of any Option to the then

          (c)  EFFECT OF ADMINISTRATOR'S DECISION. All decisions, determinations
               ----------------------------------  
and interpretations of the Administrator shall be final and binding on all
Optionees and any other holders of any Options.

     5.   ELIGIBILITY.
          -----------

               --------------------                                            
to Employees and Consultants.  Incentive Stock Options may be granted only to
Employees, provided, however, that Employees of an Affiliate shall not be
           --------  -------                                             
eligible to receive Incentive Stock Options.  An Employee or Consultant who has
been granted an Option may, if he or she is otherwise eligible, be granted an
additional Option or Options.

          (b)  TYPE OF OPTION.  Each Option shall be designated in the written
               --------------                                                 
option agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option.  However, notwithstanding such designations, to the extent that the
aggregate Fair Market Value of Shares with respect to which Incentive Stock
Options are exercisable for the first time by an Optionee during any calendar
year (under all plans of the Company or any Parent or Subsidiary) exceeds
$100,000, such excess Options shall be treated as Nonstatutory Stock Options.
For purposes of this Section 5(b), Incentive Stock Options shall be taken into
account in the order in which they were granted, and the Fair Market Value of
the Shares shall be determined as of the time the Option with respect to such
Shares is granted.

          (c)  NO EMPLOYMENT RIGHTS. The Plan shall not confer upon any Optionee
               --------------------    
any right with respect to continuation of employment or consulting relationship
with the Company, nor shall it interfere in any way with his or her right or the
Company's right to terminate his or her employment or consulting relationship at
any time, with or without cause.

Company as described in Section 20 of the Plan.  It shall continue in effect for

     7.   TERM OF OPTION.  The term of each Option shall be the term stated in
          --------------                                                      
the Option Agreement; provided, however, that in the case of an Incentive Stock
                      --------  -------                                        
Option, the term shall be no more than ten (10) years from the date of grant
thereof or such shorter term as may be provided in the Option Agreement.
However, in the case of an Incentive Stock Option granted to an Optionee who, at
the time the Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the term of the Option shall be five (5) years from the date of
grant thereof or such shorter term as may be provided in the Option Agreement.

          (b)  PERMISSIBLE CONSIDERATION.  The consideration to be paid for the
               -------------------------                                       
Shares to be issued upon exercise of an Option, including the method of payment,
shall be determined by the Administrator (and, in the case of an Incentive Stock
Option, shall be determined at the time of grant) and may consist entirely of
(1) cash, (2) other Shares that (x) in the case of Shares acquired upon exercise
of an Option either have been owned by the Optionee for more than six months on
the date of surrender or were not acquired, directly or indirectly, from the
Company, and (y) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised, or (3) such other consideration and method of payment for the
issuance of Shares to the extent permitted under Applicable Laws. In making its
determination as to the type of consideration to accept, the Administrator shall
consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

     10.  EXERCISE OF OPTION.
          ------------------ 

          (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER.  Any Option
               -----------------------------------------------             
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, including performance criteria with respect
to the Company and/or the Optionee, and as shall be permissible under the terms
of the Plan.

          An Option may not be exercised for a fraction of a Share.

          An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may, as authorized by the Administrator, consist of any
consideration and method of payment allowable under Section 9(b) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a stockholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option.  The Company shall issue (or cause
to be issued) such stock certificate promptly upon exercise of the Option.  No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 14 of the Plan.

          Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

          (b)  TERMINATION OF STATUS AS AN EMPLOYEE OR CONSULTANT.  In the event
               --------------------------------------------------               
of termination of an Optionee's Continuous Status as an Employee or Consultant,
such Optionee may, but only within thirty (30) days (or such other period of
time, not exceeding three (3) months in the case of an Incentive Stock Option or
six (6) months in the case of a Nonstatutory Stock Option, as is determined by
the Administrator, with such determination in the case of an Incentive Stock
Option being made at the time of grant of the Option) after the date of such
termination (but in no event later than the date of expiration of the term of
such Option as set forth in the Option Agreement), exercise his or her Option to
the extent that he or she was 

                                      -7-
<PAGE>
 
entitled to exercise it at the date of such termination. To the extent that the
Optionee was not entitled to exercise the Option at the date of such
termination, or if the optionee does not exercise such Option (which he or she
was entitled to exercise) within the time specified herein, the Option shall
terminate.

          (c)  DISABILITY OF OPTIONEE.  Notwithstanding Section 10(b) above, in
               ----------------------                                          
the event of termination of an Optionee's Continuous Status as an Employee or
Consultant as a result of his or her total and permanent disability (as defined
in Section 22(e)(3) of the Code), he or she may, but only within six (6) months
(or such other period of time not exceeding twelve (12) months as is determined
by the Administrator, with such determination in the case of an Incentive Stock
Option being made at the time of grant of the Option) from the date of such
termination (but in no event later than the date of expiration of the term of
such Option as set forth in the Option Agreement), exercise his or her Option to
the extent he or she was entitled to exercise it at the date of such
termination. To the extent that he or she was not entitled to exercise the
Option at the date of termination, or if he does not exercise such Option (which
he was entitled to exercise) within the time specified herein, the Option shall
terminate.

          (d)  DEATH OF OPTIONEE.  In the event of the death of an Optionee:
               -----------------                                            

               (i)   during the term of the Option who is at the time of his
death an Employee or Consultant of the Company and who shall have been in
Continuous Status as an Employee or Consultant since the date of grant of the
Option, the Option may be exercised, at any time within six (6) months (or such
other period of time, not exceeding twelve (12) months, as is determined by the
Administrator, with such determination in the case of an Incentive Stock Option
being made at the time of grant of the Option) following the date of death (but
in no event later than the date of expiration of the term of such Option as set
forth in the Option Agreement), by the Optionee's estate or by a person who
acquired the right to exercise the Option by bequest or inheritance but only to
the extent of the right to exercise that would have accrued had the Optionee
continued living and remained in Continuous Status as an Employee or Consultant
three (3) months (or such other period of time as is determined by the
Administrator as provided above) after the date of death, subject to the
limitation set forth in Section 5(b); or

               (ii)  within thirty (30) days (or such other period of time not
exceeding three (3) months as is determined by the Administrator, with such
determination in the case of an Incentive Stock Option being made at the time of
grant of the Option) after the termination of Continuous Status as an Employee
or Consultant, the Option may be exercised, at any time within six (6) months
following the date of death (but in no event later than the date of expiration
of the term of such Option as set forth in the Option Agreement), by the
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
had accrued at the date of termination.

          (e)  RULE 16B-3.  Options granted to persons subject to Section 16(b)
               ----------                                                      
of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

                                      -8-

     11.  WITHHOLDING TAXES.  As a condition to the exercise of Options granted
          -----------------                                                    
hereunder, the Optionee shall make such arrangements as the Administrator may
require for the satisfaction of any federal, state, local or foreign withholding
tax obligations that may arise in connection with the exercise, receipt or
vesting of such Option.  The Company shall not be required to issue any Shares
under the Plan until such obligations are satisfied.

     12.  STOCK WITHHOLDING TO SATISFY WITHHOLDING TAX OBLIGATIONS.  At the
          --------------------------------------------------------         
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph.  When an Optionee incurs tax liability in
connection with an Option which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by one or some combination of the
following methods:  (a) by cash payment, or (b) out of Optionee's current
compensation, or (c) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares that (i) in the case of Shares previously
acquired from the Company, have been owned by the Optionee for more than six
months on the date of surrender, and (ii) have a fair market value on the date
of surrender equal to or less than Optionee's marginal tax rate times the
ordinary income recognized, or (d) by electing to have the Company withhold from
the Shares to be issued upon exercise of the Option that number of Shares having
a fair market value equal to the amount required to be withheld.  For this
purpose, the fair market value of the Shares to be withheld shall be determined
on the date that the amount of tax to be withheld is to be determined (the "Tax
                                                                            ---
Date").
- ----   

          Any surrender by an Officer or Director of previously owned Shares to
satisfy tax withholding obligations arising upon exercise of this Option must
comply with the applicable provisions of Rule 16b-3.

          All elections by an Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

          (a)  the election must be made on or prior to the applicable Tax Date;

          (b)  once made, the election shall be irrevocable as to the particular
Shares of the Option as to which the election is made; and

          (c)  all elections shall be subject to the consent or disapproval of
the Administrator.

          In the event the election to have Shares withheld is made by an
Optionee and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Optionee shall receive
the full number of Shares with respect to which the Option is exercised but such
Optionee shall be unconditionally obligated to tender back to the Company the
proper number of Shares on the Tax Date.

                                      -9-
<PAGE>
 
     13.  NON-TRANSFERABILITY OF OPTIONS.  The Option may not be sold, pledged,
          ------------------------------                                       
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution; provided that the Administrator
                                                --------                       
may in its discretion grant transferable Nonstatutory Stock Options pursuant to
option agreements specifying (i) the manner in which such Nonstatutory Stock
Options are transferable and (ii) that any such transfer shall be subject to the
Applicable Laws. The designation of a beneficiary by an Optionee will not
constitute a transfer. An Option may be exercised, during the lifetime of the
Optionee, only by the Optionee or a transferee permitted by this Section 13.

     14.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS.
          ------------------------------------------------------------------ 

          (a)  ADJUSTMENT. Subject to any required action by the stockholders of
               ----------  
the Company, the number of shares of Common Stock covered by each outstanding
Option, the number of shares of Common Stock that have been authorized for
issuance under the Plan but as to which no Options have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option, the maximum number of shares of Common Stock for which Options may be
granted to any employee under Section 8 of the Plan, and the price per share of
Common Stock covered by each such outstanding Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such adjustment shall be made by the
Administrator, whose determination in that respect shall be final, binding and
conclusive.  Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an Option.

          (b)  CORPORATE TRANSACTIONS.  In the event of the proposed dissolution
               ----------------------                                           
or liquidation of the Company, the Option will terminate immediately prior to
the consummation of such proposed action, unless otherwise provided by the
Administrator.  The Administrator may, in the exercise of its sole discretion in
such instances, declare that any Option shall terminate as of a date fixed by
the Administrator and give each Optionee the right to exercise his or her Option
as to all or any part of the Optioned Stock, including Shares as to which the
Option would not otherwise be exercisable.  In the event of a proposed sale of
all or substantially all of the assets of the Company, or the merger of the
Company with or into another corporation, the Option shall be assumed or an
equivalent option shall be substituted by such successor corporation or a parent
or subsidiary of such successor corporation, unless the Administrator
determines, in the exercise of its sole discretion and in lieu of such
assumption or substitution, that the Optionee shall have the right to exercise
the Option as to some or all of the Optioned Stock, including Shares as to which
the Option would not otherwise be exercisable.  If the Administrator makes an
Option exercisable in lieu of assumption or substitution in the event of a
merger or sale of assets, the Administrator shall notify the Optionee that the
Option shall be 

                                     -10-
<PAGE>
 
exercisable for a period of thirty (30) days from the date of such notice, and
the Option will terminate upon the expiration of such period.

     15.  TIME OF GRANTING OPTIONS.  The date of grant of an Option shall, for
          ------------------------                                            
all purposes, be the date on which the Administrator makes the determination
granting such Option or such other date as is determined by the Administrator;
provided however that in the case of any Incentive Stock Option, the grant date
- -------- -------                                                               
shall be the later of the date on which the Administrator makes the
determination granting such Incentive Stock Option or the date of commencement
of the Optionee's employment relationship with the Company. Notice of the
determination shall be given to each Employee or Consultant to whom an Option
is so granted within a reasonable time after the date of such grant.

     16.  AMENDMENT AND TERMINATION OF THE PLAN.
          ------------------------------------- 

          (a)  AMENDMENT AND TERMINATION.  The Board may amend or terminate the
               -------------------------                                       
Plan from time to time in such respects as the Board may deem advisable;
provided that, the following revisions or amendments shall require approval of
the stockholders of the Company in the manner described in Section 20 of the
Plan:

               (i)   any increase in the number of Shares subject to the Plan,
other than an adjustment under Section 14 of the Plan;

               (ii)  any change in the designation of the class of persons
eligible to be granted Options; or

               (iii) any change in the limitation on grants to employees as
described in Section 8 of the Plan or other changes which would require
stockholder approval to qualify options granted hereunder as performance-based
compensation under Section 162(m) of the Code.

          (b)  STOCKHOLDER APPROVAL.  If any amendment requiring stockholder
               --------------------                                         
approval under Section 16(a) of the Plan is made subsequent to the first
registration of any class of equity securities by the Company under Section 12
of the Exchange Act, such stockholder approval shall be solicited as described
in Section 20 of the Plan.

          (c)  EFFECT OF AMENDMENT OR TERMINATION.  Any such amendment or
               ----------------------------------                        
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

     17.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued
          ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may

                                     -11-
<PAGE>
 
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

          As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

     18.  RESERVATION OF SHARES.  The Company, during the term of this Plan,
          ---------------------                                             
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.  The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

     19.  OPTION AGREEMENT.  Options shall be evidenced by written option
          ----------------                                               
agreements in such form as the Board shall approve.

     20.  STOCKHOLDER APPROVAL.
          -------------------- 

          (a)  Continuance of the Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months before or after the date
the Plan is adopted.  Such stockholder approval shall be obtained in the manner
and to the degree required under applicable federal and state law and the rules
of any stock exchange upon which the Shares are listed.

          (b)  In the event that the Company registers any class of equity
securities pursuant to Section 12 of the Exchange Act, any required approval of
the stockholders of the Company obtained after such registration shall be
solicited substantially in accordance with Section 14(a) of the Exchange Act and
the rules and regulations promulgated thereunder.

          (c)  If any required approval by the stockholders of the Plan itself
or of any amendment thereto is solicited at any time otherwise than in the
manner described in Section 20(b) hereof, then the Company shall, at or prior to
the first annual meeting of stockholders held subsequent to the later of (1) the
first registration of any class of equity securities of the Company under
Section 12 of the Exchange Act or (2) the granting of an Option hereunder to an
officer or director after such registration, do the following:

               (i)   furnish in writing to the holders entitled to vote for the
Plan substantially the same information that would be required (if proxies to be
voted with respect to approval or disapproval of the Plan or amendment were then
being solicited) by the rules and regulations in effect under Section 14(a) of
the Exchange Act at the time such information is furnished; and

                                     -12-
<PAGE>
 
               (ii)  file with, or mail for filing to, the Securities and
Exchange Commission four copies of the written information referred to in
subsection (i) hereof not later than the date on which such information is first
sent or given to stockholders.

                                                               ----             
the Company, which is incorporated in this Agreement by reference.  In the event
of a conflict between the terms of the Plan and the terms of this Agreement, the
terms of the Plan shall govern.  Unless otherwise defined in this Agreement, the
terms used in this Agreement shall have the meanings defined in the Plan.

          To the extent designated an Incentive Stock Option in the Notice of
Stock Option Grant, this Option is intended to qualify as an Incentive Stock
Option as defined in Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code") and, to the extent not so designated, this Option is
              ----                                                       
intended to be a Nonstatutory Stock Option.

     2.   EXERCISE OF OPTION.  This Option shall be exercisable during its term
          ------------------                                                   
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant and with the provisions of Sections 9 and 10 of the Plan as follows:

          (a)  RIGHT TO EXERCISE.
               ----------------- 

               (i)    This Option may not be exercised for a fraction of a
share.

               (ii)   In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by
Sections 6, 7 and 8 below, subject to the limitations contained in paragraphs
(iii) and (iv) below.

               (iii)  In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in the Notice of Stock Option
Grant.

               (iv)   If designated an Incentive Stock Option in the Notice of
Stock Option Grant, in the event that the Shares subject to this Option (and all
other Incentive Stock Options granted to Optionee by the Company or any Parent
or Subsidiary) that vest in any calendar year have an aggregate fair market
value (determined for each Share as of the Date of Grant of the option covering
such Share) in excess of $100,000, the Shares in excess of $100,000 shall be
treated as subject to a Nonstatutory Stock Option, in accordance with Section 5
of the Plan.
<PAGE>
 
          (b)  METHOD OF EXERCISE.
               ------------------ 

               (i)    This Option shall be exercisable by delivering to the
Company a written notice of exercise (in the form attached as Exhibit A) which
                                                              --------- 
shall state the election to exercise the Option, the number of Shares in respect
of which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such Shares of
Common Stock as may be required by the Company pursuant to the provisions of the
Plan. Such written notice shall be signed by Optionee and shall be delivered in
person or by certified mail to the Secretary of the Company. The written notice
shall be accompanied by payment of the Exercise Price. This Option shall be
deemed to be exercised upon receipt by the Company of such written notice
accompanied by the Exercise Price.

               (ii)   As a condition to the exercise of this Option, Optionee
agrees to make adequate provision for federal, state or other tax withholding
obligations, if any, which arise upon the exercise of the Option or disposition
of Shares, whether by withholding, direct payment to the Company, or otherwise.

               (iii)  No Shares will be issued pursuant to the exercise of an
Option unless such issuance and such exercise shall comply with all relevant
provisions of law and the requirements of any stock exchange upon which the
Shares may then be listed. Assuming such compliance, for income tax purposes the
Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

     3.   OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable
          --------------------------                                      
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), at the time this
                                         --------------                    
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.

     4.   METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of
          -----------------                                                   
the following, or a combination of the following, at the election of Optionee:
(a) cash; (b) check; (c) surrender of other Shares of Common Stock of the
Company that (i) either have been owned by Optionee for more than six (6) months
on the date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; (d) authorization from the Company to retain from the total number of
Shares as to which the Option is exercised that number of Shares having a Fair
Market value on the date of exercise equal to the exercise price for the total
number of Shares as to which the Option is exercised; or (e) if there is a
public market for the Shares and they are registered under the Securities Act,
delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the exercise price.

     5.   RESTRICTIONS ON EXERCISE.  This Option may not be exercised until such
          ------------------------                                              
time as the Plan has been approved by the stockholders of the Company, or if the
issuance of such Shares 
<PAGE>
 
upon such exercise or the method of payment of consideration for such shares
would constitute a violation of any applicable federal or state securities or
other law or regulation, including any rule under Part 207 of Title 12 of the
Code of Federal Regulations ("Regulation G") as promulgated by the Federal
Reserve Board. As a condition to the exercise of this Option, the Company may
require Optionee to make any representation and warranty to the Company as may
be required by any applicable law or regulation.

     6.   TERMINATION OF RELATIONSHIP.  In the event of termination of 
          --------------------------- 
Optionee's Continuous Status as an Employee or Consultant, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
                                                                   -----------  
Date"), exercise this Option during the Termination Period set out in the Notice
- ----
of Stock Option Grant. To the extent that Optionee was not entitled to exercise
this Option at the date of such termination, or if Optionee does not exercise
this Option within the time specified in the Notice of Stock Option Grant, the
Option shall terminate.

     7.   DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
          ----------------------                                              
above, in the event of termination of Optionee's Continuous Status as an
Employee or Consultant as a result of total and permanent disability (as defined
in Section 22(e)(3) of the Code), Optionee may, but only within six (6) months
from the date of termination of employment (but in no event later than the date
of expiration of the term of this Option as set forth in Section 10 below),
exercise the Option to the extent otherwise so entitled at the date of such
termination.  To the extent that Optionee was not entitled to exercise the
Option at the date of termination, or if Optionee does not exercise such Option
(to the extent otherwise so entitled) within the time specified in this
Agreement, the Option shall terminate.

     8.   DEATH OF OPTIONEE.  In the event of the death of Optionee:
          -----------------                                         

          (a) during the term of this Option and while an Employee of the
Company and having been in Continuous Status as an Employee or Consultant since
the date of grant of the Option, the Option may be exercised, at any time within
six (6) months following the date of death (but in no event later than the date
of expiration of the term of this Option as set forth in Section 10 below), by
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
would have accrued had Optionee continued living and remained in Continuous
Status as an Employee or Consultant three (3) months after the date of death,
subject to the limitation contained in Section 2(i)(d) above in the case of an
Incentive Stock Option; or

          (b) within thirty (30) days after the termination of Optionee's
Continuous Status as an Employee or Consultant, the Option may be exercised, at
any time within six (6) months following the date of death (but in no event
later than the date of expiration of the term of this Option as set forth in
Section 10 below), by Optionee's estate or by a person who acquired the right to
exercise the Option by bequest or inheritance, but only to the extent of the
right to exercise that had accrued at the date of termination.

     9.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
          -----------------------------                                        
any manner otherwise than by will or by the laws of descent or distribution.
The designation of a 

                                      -3-
<PAGE>
 
beneficiary does not constitute a transfer. An Option may be exercised during
the lifetime of Optionee only by Optionee or a transferee permitted by this
section. The terms of this Option shall be binding upon the executors,
administrators, heirs, successors and assigns of Optionee.

     10.  TERM OF OPTION.  This Option may be exercised only within the term set
          --------------                                                        
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the Plan and the terms of this Option.

     11.  NO ADDITIONAL EMPLOYMENT RIGHTS.  Optionee understands and agrees that
          -------------------------------                                       
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an Employee or Consultant at the will of the Company (not through
the act of being hired, being granted this Option or acquiring Shares under this
Agreement).  Optionee further acknowledges and agrees that nothing in this
Agreement, nor in the Plan which is incorporated in this Agreement by reference,
shall confer upon Optionee any right with respect to continuation as an Employee
or Consultant with the Company, nor shall it interfere in any way with his or
her right or the Company's right to terminate his or her employment or
consulting relationship at any time, with or without cause.

     12.  TAX CONSEQUENCES.  Optionee acknowledges that he or she has read the
          ----------------                                                    
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant.  OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE, AND
THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT HIS
OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a) EXERCISE OF INCENTIVE STOCK OPTION.  If this Option is an
              ----------------------------------                       
Incentive Stock Option, there will be no regular federal income tax liability
upon the exercise of the Option, although the excess, if any, of the fair market
value of the Shares on the date of exercise over the Exercise Price will be
treated as an item of alternative minimum taxable income for federal tax
purposes and may subject Optionee to the alternative minimum tax in the year of
exercise.

          (b) EXERCISE OF NONSTATUTORY STOCK OPTION.  If this Option does not
              -------------------------------------                          
qualify as an Incentive Stock Option, Optionee may incur regular federal income
tax liability upon the exercise of the Option.  Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the fair market value of the Shares on the date of
exercise over the Exercise Price.  In addition, if Optionee is an employee of
the Company, the Company will be required to withhold from Optionee's
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

          (c) DISPOSITION OF SHARES.  If this Option is an Incentive Stock
              ---------------------                                       
Option and if Shares transferred pursuant to the Option are held for more than
one year after exercise and more than two years after the Date of Grant, any
gain realized on disposition of the Shares will be treated as long-term capital
gain for federal income tax purposes.  If Shares purchased under an Incentive
Stock Option are disposed of before the end of either of such two holding
periods, then 

                                      -4-
<PAGE>
 
any gain realized on such disposition will be treated as compensation income
(taxable at ordinary income rates) to the extent of the excess, if any, of the
lesser of (i) the fair market value of the Shares on the date of exercise, or
(ii) the sales proceeds, over the Exercise Price. If this Option is a
Nonstatutory Stock Option, then gain realized on the disposition of Shares will
be treated as long-term or short-term capital gain depending on whether or not
the disposition occurs more than one year after the exercise date.

          (d) NOTICE OF DISQUALIFYING DISPOSITION.  If the Option granted to
              -----------------------------------                           
Optionee in this Agreement is an Incentive Stock Option, and if Optionee sells
or otherwise disposes of any of the Shares acquired pursuant to the Incentive
Stock Option on or before the later of (i) the date two years after the Date of
Grant, or (ii) the date one year after transfer of such Shares to Optionee upon
exercise of the Incentive Stock Option, Optionee shall notify the Company in
writing within thirty (30) days after the date of any such disposition.
Optionee agrees that Optionee may be subject to income tax withholding by the
Company on the compensation income recognized by Optionee from the early
disposition by payment in cash or out of the current earnings paid to Optionee.

     13.  SIGNATURE.  This Stock Option Agreement shall be deemed executed by
          ---------                                                          
the Company and Optionee upon execution by such parties of the Notice of Stock
Option Grant attached to this Stock Option Agreement.

each calendar year in which such option is outstanding at any time.

     4.   Offering Periods and Purchase Periods.
          --------------------------------------

          (a)  Offering Periods.  The Plan shall be implemented by a series of
               ----------------                                               
Offering Periods of twenty-four (24) months duration, with new Offering Periods
commencing on or 

                                      -2-
<PAGE>
 
about February 1 and August 1 of each year (or at such other time or times as
may be determined by the Board of Directors). The first Offering Period shall
commence on the beginning of the effective date of the Registration Statement on
Form S-1 for the initial public offering of the Company's Common Stock (the "IPO
Date") and continue until July 31, 1999. The Plan shall continue until
terminated in accordance with Section 19 hereof. The Board of Directors of the
Company shall have the power to change the duration and/or the frequency of
Offering Periods with respect to future offerings without shareholder approval
if such change is announced at least fifteen (15) days prior to the scheduled
beginning of the first Offering Period to be affected. Eligible employees may
not participate in more than one Offering Period at a time.

          (b)  Purchase Periods.  Each Offering Period shall consist of two (2)
               ----------------                                                
consecutive purchase periods of six (6) months duration.  The last day of each
Purchase Period shall be the "Purchase Date" for such Purchase Period.  A
Purchase Period commencing on February 1 shall end on the next July 31.  A
Purchase Period commencing on August 1 shall end on the next January 31.  The
first Purchase Period shall commence on the IPO Date and shall end on July 31,
1998.  The Board of Directors of the Company shall have the power to change the
duration and/or frequency of Purchase Periods with respect to future purchases
without shareholder approval if such change is announced at least fifteen (15)
days prior to the scheduled beginning of the first Purchase Period to be
affected.

     5.   Participation.
          ------------- 

          (a)  An eligible Employee may become a participant in the Plan by
completing a subscription agreement on the form provided by the Company and
filing it with the Company's payroll office prior to the applicable Offering
Date, unless a later time for filing the subscription agreement is set by the
Board for all eligible Employees with respect to a given offering.  The
subscription agreement shall set forth the percentage of the participant's
Compensation (which shall be not less than 1% and not more than 15%) to be paid
as Contributions pursuant to the Plan.

          (b)  Payroll deductions shall commence on the first payroll following
the Offering Date and shall end on the last payroll paid on or prior to the last
Purchase Period of the Offering Period to which the subscription agreement is
applicable, unless sooner terminated by the participant as provided in Section
10.

     6.   Method of Payment of Contributions.
          ---------------------------------- 

          (a)  The participant shall elect to have payroll deductions made on
each payday during the Offering Period in an amount not less than one percent
(1%) and not more than fifteen percent (15%) of such participant's Compensation
on each such payday.  All payroll deductions made by a participant shall be
credited to his or her account under the Plan.  A participant may not make any
additional payments into such account.

          (b)  A participant may discontinue his or her participation in the
Plan as provided in Section 10, or, on one occasion only during the Offering
Period, may decrease the 

                                      -3-
<PAGE>
 
rate of his or her Contributions during the Offering Period by completing and
filing with the Company a new subscription agreement. The change in rate shall
be effective as of the beginning of the next calendar month following the date
of filing of the new subscription agreement, if the agreement is filed at least
ten (10) business days prior to such date and, if not, as of the beginning of
the next succeeding calendar month.

          (c)  Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) herein, a participant's
payroll deductions may be decreased to 0% at such time during any Offering
Period which is scheduled to end during the current calendar year that the
aggregate of all payroll deductions accumulated with respect to such Offering
Period and any other Offering Period ending within the same calendar year equal
$21,250.  Payroll deductions shall re-commence at the rate provided in such
participant's subscription Agreement at the beginning of the first Offering
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10.

     7.   Grant of Option.
          --------------- 

          (a)  On the Offering Date of each Offering Period, each eligible
Employee participating in such Offering Period shall be granted an option to
purchase on each Purchase Date a number of shares of the Company's Common Stock
determined by dividing such Employee's Contributions accumulated prior to such
Purchase Date and retained in the participant's account as of the Purchase Date
by the lower of (i) eighty-five percent (85%) of the fair market value of a
share of the Company's Common Stock on the Offering Date, or (ii) eighty-five
percent (85%) of the fair market value of a share of the Company's Common Stock
on the Purchase Date; provided however, that the maximum number of shares an
Employee may purchase during each Offering Period shall be determined at the
Offering Date by dividing $25,000 by the fair market value of a share of the
Company's Common Stock on the Offering Date, and provided further that such
purchase shall be subject to the limitations set forth in Sections 3(b) and 13.
The fair market value of a share of the Company's Common Stock shall be
determined as provided in Section 7(b).

          (b)  The option price per share of the shares offered in a given
Offering Period shall be the lower of:  (i) 85% of the fair market value of a
share of the Common Stock of the Company on the Offering Date; or (ii) 85% of
the fair market value of a share of the Common Stock of the Company on the
Purchase Date.  The fair market value of the Company's Common Stock on a given
date shall be determined by the Board in its discretion based on the closing
price of the Common Stock for such date (or, in the event that the Common Stock
is not traded on such date, on the immediately preceding trading date), as
reported by the National Association of Securities Dealers Automated Quotation
(Nasdaq) National Market or, if such price is not reported, the mean of the bid
and asked prices per share of the Common Stock as reported by Nasdaq or, in the
event the Common Stock is listed on a stock exchange, the fair market value per
share shall be the closing price on such exchange on such date (or, in the event
that the Common Stock is not traded on such date, on the immediately preceding
trading date), as reported in The Wall Street Journal.  For purposes of the
Offering Date under the first Offering Period under the Plan, the fair market
value of a share of the Common Stock of the Company 

                                      -4-
<PAGE>
 
shall be the Price to Public as set forth in the final prospectus filed with the
Securities and Exchange Commission pursuant to Rule 424 under the Securities Act
of 1933, as amended.

     8.   Exercise of Option.  Unless a participant withdraws from the Plan as
          ------------------                                                  
provided in paragraph 10, his or her option for the purchase of shares will be
exercised automatically on each Purchase Date of an Offering Period, and the
maximum number of full shares subject to the option will be purchased at the
applicable option price with the accumulated Contributions in his or her
account.  The shares purchased upon exercise of an option hereunder shall be
deemed to be transferred to the participant on the Purchase Date.   No
fractional shares shall be purchased.  Any payroll deductions accumulated in a
participant's account which are not sufficient to purchase a full share shall be
retained in the participant's account for the subsequent Purchase Period or
Offering Period, subject to earlier withdrawal by the participant as provided in
Section 10.  Any other monies left over in a participant's account after a
Purchase Date shall be returned to the Participant.  During his or her lifetime,
a participant's option to purchase shares hereunder is exercisable only by him
or her.

     9.   Delivery.  As promptly as practicable after each Purchase Date of each
          --------                                                              
Offering Period, the Company shall arrange the delivery to each participant, as
appropriate, of a certificate representing the shares purchased upon exercise of
his or her option or the deposit of such number of shares with the broker
selected by the Company for administration of  Plan stock purchases, as
determined by the Company.

     10.  Voluntary Withdrawal; Termination of Employment.
          ----------------------------------------------- 

          (a)  A participant may withdraw all but not less than all the
Contributions credited to his or her account under the Plan at any time at least
ten (10) business days prior to each Purchase Date by giving written notice to
the Company.  All of the participant's Contributions credited to his or her
account will be paid to him or her promptly after receipt of his or her notice
of withdrawal and his or her option for the current period will be automatically
terminated, and no further Contributions for the purchase of shares will be made
during the Offering Period.

          (b)  Upon termination of the participant's Continuous Status as an
Employee prior to the Purchase Date of an Offering Period for any reason,
including retirement or death, the Contributions credited to his or her account
will be returned to him or her or, in the case of his or her death, to the
person or persons entitled thereto under Section 14, and his or her option will
be automatically terminated.

          (c)  In the event an Employee fails to remain in Continuous Status as
an Employee of the Company for at least twenty (20) hours per week during the
Offering Period in which the employee is a participant, he or she will be deemed
to have elected to withdraw from the Plan and the Contributions credited to his
or her account will be returned to him or her and his or her option terminated.

                                      -5-
<PAGE>
 
          (d)  A participant's withdrawal from an offering will not have any
effect upon his or her eligibility to participate in a succeeding offering or in
any similar plan which may hereafter be adopted by the Company.

     11.  Automatic Withdrawal.  If the fair market value of the shares on the
          --------------------                                                
first Purchase Date of an Offering Period is less than the fair market value of
the shares on the Offering Date for such Offering Period, then every participant
shall automatically (i) be withdrawn from such Offering Period at the close of
such Purchase Date and after the acquisition of shares for such Purchase Period,
and (ii) be enrolled in the Offering Period commencing on the first business day
subsequent to such Purchase Period.

     12.  Interest.  No interest shall accrue on the Contributions of a
          --------                                                     
participant in the Plan.

     13.  Stock.
          ----- 

          (a)  The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 500,000 shares subject
to adjustment upon changes in capitalization of the Company as provided in
Section 18.  If the total number of shares which would otherwise be subject to
options granted pursuant to Section 7(a) on the Offering Date of an Offering
Period exceeds the number of shares then available under the Plan (after
deduction of all shares for which options have been exercised or are then
outstanding), the Company shall make a pro rata allocation of the shares
remaining available for option grant in as uniform a manner as shall be
practicable and as it shall determine to be equitable.  In such event, the
Company shall give written notice of such reduction of the number of shares
subject to the option to each Employee affected thereby and shall similarly
reduce the rate of Contributions, if necessary.

          (b)  The participant will have no interest or voting right in shares
covered by his or her option until such option has been exercised.

          (c)  Shares to be delivered to a participant under the Plan will be
registered in the name of the participant or in the name of the participant and
his or her spouse.

     14.  Administration.  The Board, or a committee named by the Board, shall
          --------------                                                      
supervise and administer the Plan and shall have full power to adopt, amend and
rescind any rules deemed desirable and appropriate for the administration of the
Plan and not inconsistent with the Plan, to construe and interpret the Plan, and
to make all other determinations necessary or advisable for the administration
of the Plan.  The composition of the committee shall be in accordance with the
requirements to obtain or retain any available exemption from the operation of
Section 16(b) of the Exchange Act pursuant to Rule 16b-3 promulgated thereunder.

     15.  Designation of Beneficiary.
          -------------------------- 

          (a)  A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to the end of a
Purchase Period but prior to delivery to him 

                                      -6-
<PAGE>
 
or her of such shares and cash. In addition, a participant may file a written
designation of a beneficiary who is to receive any cash from the participant's
account under the Plan in the event of such participant's death prior to the
Purchase Date of an Offering Period. If a participant is married and the
designated beneficiary is not the spouse, spousal consent shall be required for
such designation to be effective.

          (b)  Such designation of beneficiary may be changed by the participant
(and his or her spouse, if any) at any time by written notice.  In the event of
the death of a participant and in the absence of a beneficiary validly
designated under the Plan who is living at the time of such participant's death,
the Company shall deliver such shares and/or cash to the executor or
administrator of the estate of the participant, or if no such executor or
administrator has been appointed (to the knowledge of the Company), the Company,
in its discretion, may deliver such shares and/or cash to the spouse or to any
one or more dependents or relatives of the participant, or if no spouse,
dependent or relative is known to the Company, then to such other person as the
Company may designate.

     16.  Transferability.  Neither Contributions credited to a participant's
          ---------------                                                    
account nor any rights with regard to the exercise of an option or to receive
shares under the Plan may be assigned, transferred, pledged or otherwise
disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in Section 14) by the participant.  Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds in accordance with Section 10.

     17.  Use of Funds.  All Contributions received or held by the Company under
          ------------                                                          
the Plan may be used by the Company for any corporate purpose, and the Company
shall not be obligated to segregate such Contributions.

     18.  Reports.  Individual accounts will be maintained for each participant
          -------                                                              
in the Plan.  Statements of account will be given to participating Employees
promptly following the Purchase Date, which statements will set forth the
amounts of Contributions, the per share purchase price, the number of shares
purchased and the remaining cash balance, if any.

     19.  Adjustments Upon Changes in Capitalization; Corporate Transactions.
          ------------------------------------------------------------------ 

          (a)  Adjustment. Subject to any required action by the shareholders of
               ----------
the Company, the number of shares of Common Stock covered by each option under
the Plan which has not yet been exercised and the number of shares of Common
Stock which have been authorized for issuance under the Plan but have not yet
been placed under option (collectively, the "Reserves"), as well as the price
per share of Common Stock covered by each option under the Plan which has not
yet been exercised, shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of shares of
Common Stock effected without receipt of consideration by the Company; provided,
however, that conversion of any convertible securities of the Company shall not
be deemed to have been "effected without receipt of consideration". Such
adjustment shall be made by the Board, whose determination in that respect shall
be final, 

                                      -7-
<PAGE>
 
binding and conclusive. Except as expressly provided herein, no issue by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock subject
to an option.

          (b)  Corporate Transactions. In the event of the proposed dissolution
               ----------------------                          
or liquidation of the Company, the Offering Period will terminate immediately
prior to the consummation of such proposed action, unless otherwise provided by
the Board. In the event of a proposed sale of all or substantially all of the
assets of the Company, or the merger of the Company with or into another
corporation, each option under the Plan shall be assumed or an equivalent option
shall be substituted by such successor corporation or a parent or subsidiary of
such successor corporation, unless the Board determines, in the exercise of its
sole discretion and in lieu of such assumption or substitution, to shorten the
Offering Period then in progress by setting a new Purchase Date (the "New
Purchase Date"). If the Board shortens the Offering Period then in progress in
lieu of assumption or substitution in the event of a merger or sale of assets,
the Board shall notify each participant in writing, at least ten (10) days prior
to the New Purchase Date, that the Purchase Date for his or her option has been
changed to the New Purchase Date and that his or her option will be exercised
automatically on the New Purchase Date, unless prior to such date he or she has
withdrawn from the Offering Period as provided in Section 10. For purposes of
this paragraph, an option granted under the Plan shall be deemed to be assumed
if, following the sale of assets or merger, the option confers the right to
purchase, for each share of option stock subject to the option immediately prior
to the sale of assets or merger, the consideration (whether stock, cash or other
securities or property) received in the sale of assets or merger by holders of
Common Stock for each share of Common Stock held on the effective date of the
transaction (and if such holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
shares of Common Stock); provided, however, that if such consideration received
in the sale of assets or merger was not solely common stock of the successor
corporation or its parent (as defined in Section 424(e) of the Code), the Board
may, with the consent of the successor corporation and the participant, provide
for the consideration to be received upon exercise of the option to be solely
common stock of the successor corporation or its parent equal in fair market
value to the per share consideration received by holders of Common Stock and the
sale of assets or merger.

          The Board may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of shares of its outstanding Common
Stock, and in the event of the Company being consolidated with or merged into
any other corporation.

     20.  Amendment or Termination.
          ------------------------ 

          (a)  The Board of Directors of the Company may at any time terminate
or amend the Plan. Except as provided in Section 19, no such termination may
affect options previously granted, nor may an amendment make any change in any
option theretofore granted 

                                      -8-
<PAGE>
 
which adversely affects the rights of any participant. In addition, to the
extent necessary to comply with Rule 16b-3 under the Exchange Act, or under
Section 423 of the Code (or any successor rule or provision or any applicable
law or regulation), the Company shall obtain shareholder approval in such a
manner and to such a degree as so required.

          (b)  Without shareholder consent and without regard to whether any
participant rights may be considered to have been adversely affected, the Board
(or its committee) shall be entitled to change the Offering Periods and Purchase
Periods, limit the frequency and/or number of changes in the amount withheld
during an Offering Period, establish the exchange ratio applicable to amounts
withheld in a currency other than U.S. dollars, permit payroll withholding in
excess of the amount designated by a participant in order to adjust for delays
or mistakes in the Company's processing of properly completed withholding
elections, establish reasonable waiting and adjustment periods and/or accounting
and crediting procedures to ensure that amounts applied toward the purchase of
Common Stock for each participant properly correspond with amounts withheld from
the participant's Compensation, and establish such other limitations or
procedures as the Board (or its committee) determines in its sole discretion
advisable which are consistent with the Plan.

     21.  Notices.  All notices or other communications by a participant to the
          -------                                                              
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

     22.  Conditions Upon Issuance of Shares.  Shares shall not be issued with
          ----------------------------------                                  
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, and the requirements of any stock exchange upon which
the shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

          As a condition to the exercise of an option, the Company may require
the person exercising such option to represent and warrant at the time of any
such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

     23.  Term of Plan; Effective Date.  The Plan shall become effective upon
          ----------------------------                                       
the earlier to occur of its adoption by the Board of Directors or its approval
by the shareholders of the Company.  It shall continue in effect for a term of
twenty (20) years unless sooner terminated under Section 20.

     24.  Additional Restrictions of Rule 16b-3.  The terms and conditions of
          -------------------------------------                              
options granted hereunder to, and the purchase of shares by, persons subject to
Section 16 of the Exchange Act shall comply with the applicable provisions of
Rule 16b-3.  This Plan shall be deemed to contain, and such options shall
contain, and the shares issued upon exercise thereof 

                                      -9-
<PAGE>
 
shall be subject to, such additional conditions and restrictions as may be
required by Rule 16b-3 to qualify for the maximum exemption from Section 16 of
the Exchange Act with respect to Plan transactions.

future Offering Periods by filing a new Subscription Agreement, and any such
change will be effective as of the beginning of the next Offering Period.  In
addition, I acknowledge that, unless I discontinue my participation in the Plan
as provided in Section 10 of the Plan, my election will continue to be effective

                                           _____________________________________

     7.  In the event of my death, I hereby designate the following as my
beneficiary(ies) to receive all payments and shares due to me under the Plan:


NAME:  (Please print)                      _____________________________________
                                           (First)       (Middle)        (Last)

     8.  I understand that if I dispose of any shares received by me pursuant to
the Plan within 2 years after the Offering Date (the first day of the Offering
Period during which I purchased such shares) or within 1 year after the Purchase
Date, I will be treated for federal income tax purposes as having received
ordinary compensation income at the time of such disposition in an amount equal
to the excess of the fair market value of the shares on the Purchase Date over
the price which I paid for the shares, regardless of whether I disposed of the
shares at a price less than their fair market value at the Purchase Date. The
remainder of the gain or loss, if any, recognized on such disposition will be
treated as capital gain or loss.

         I hereby agree to notify the Company in writing within 30 days after
         --------------------------------------------------------------------

withholding obligation including any withholding necessary to make available to
the Company any tax deductions or benefits attributable to the sale or early
disposition of Common Stock by me.

     9.  If I dispose of such shares at any time after expiration of the 2-year
and 1-year holding periods, I understand that I will be treated for federal
income tax purposes as having received compensation income only to the extent of
an amount equal to the lesser of (1) the excess of the fair market value of the
shares at the time of such disposition over the purchase price which I paid for
the shares under the option, or (2) 15% of the fair market value of the
<PAGE>
 
shares on the Offering Date.  The remainder of the gain or loss, if any,
recognized on such disposition will be treated as capital gain or loss.

     I understand that this tax summary is only a summary and is subject to
     ----------------------------------------------------------------------
change.  I further understand that I should consult a tax advisor concerning the

tax implications of the purchase and sale of stock under the Plan.

     10.  I hereby agree to be bound by the terms of the Plan.  The

     4.   Administration of and Grants of Options under the Plan.
          ------------------------------------------------------ 

          (a)  Administrator.  Except as otherwise required herein, the Plan
               -------------

               --------------------                                           
automatic and nondiscretionary and shall be made strictly in accordance with the
following provisions:

               (i)   No person shall have any discretion to select which Outside
Directors shall be granted Options or to determine the number of Shares to be
covered by Options granted to Outside Directors.

               (ii)  Each Outside Director shall be automatically granted an
Option to purchase 20,000 Shares (the "First Option") on the date on which such
person first becomes an Outside Director after the effective date of the Plan,
whether through election by the shareholders of the Company or appointment by
the Board of Directors to fill a vacancy.

               (iii) Each Outside Director shall be automatically granted an
Option to purchase 5,000 Shares (a "Subsequent Option") on the date of each
Annual Meeting of the Company's shareholders following which such Outside
Director is serving on the Board, provided that, on such date, he or she shall
have served on the Board for at least six (6) months prior to the date of such
Annual Meeting.

               (iv)  Notwithstanding the provisions of subsections (ii) and
(iii) hereof, in the event that a grant would cause the number of Shares subject
to outstanding Options plus the number of Shares previously purchased upon
exercise of Options to exceed the Pool, then each such automatic grant shall be
for that number of Shares determined by dividing the total number of

                                      -2-
<PAGE>
 
Shares remaining available for grant by the number of Outside Directors on the
automatic grant date. Any further grants shall then be deferred until such time,
if any, as additional Shares become available for grant under the Plan through
action of the shareholders to increase the number of Shares which may be issued
under the Plan or through cancellation or expiration of Options previously
granted hereunder.

               (v)   Notwithstanding the provisions of subsections (ii) and
(iii) hereof, any grant of an Option made before the Company has obtained
shareholder approval of the Plan in accordance with Section 17 hereof shall be
conditioned upon obtaining such shareholder approval of the Plan in accordance
with Section 17 hereof.

               (vi)  The terms of each First Option granted hereunder shall be
as follows:

                     (1)  the First Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Section 9 hereof.

                     (2)  the exercise price per Share shall be 100% of the fair
market value per Share at the beginning of the date of grant of the First
Option, determined in accordance with Section 8 hereof.

                     (3)  the First Option shall become exercisable in
installments cumulatively as to 25% of the Shares subject to the First Option on
each of the first, second, third and fourth anniversaries of the date of grant
of the First Option.

               (vii) The terms of each Subsequent Option granted hereunder shall
be as follows:

                     (1)  the Subsequent Option shall be exercisable only while
the Outside Director remains a Director of the Company, except as set forth in
Section 9 hereof.

                     (2)  the exercise price per Share shall be 100% of the fair
market value per Share at the beginning of the date of grant of the Subsequent
Option, determined in accordance with Section 8 hereof.

                     (3)  the Subsequent Option shall become exercisable as to
one hundred percent (100%) of the Shares subject to the Subsequent Option on the
first anniversary of the date of grant of the Subsequent Option.

          (c)  Powers of the Board.  Subject to the provisions and restrictions
               -------------------                                             
of the Plan, the Board shall have the authority, in its discretion:  (i) to
determine, upon review of relevant information and in accordance with Section
8(b) of the Plan, the fair market value of the Common Stock; (ii) to determine
the exercise price per share of Options to be granted, which exercise price
shall be determined in accordance with Section 8(a) of the Plan; (iii) to
interpret the Plan; (iv) to prescribe, amend and rescind rules and regulations
relating to the Plan; (v) to authorize any person to execute on behalf of the
Company any instrument required to effectuate the grant of an Option

                                      -3-
<PAGE>
 
previously granted hereunder; and (vi) to make all other determinations deemed
necessary or advisable for the administration of the Plan.

          (d)  Effect of Board's Decision.  All decisions, determinations and
               --------------------------                                    
interpretations of the Board shall be final and binding on all Optionees and any
other holders of any Options granted under the Plan.

          (e)  Suspension or Termination of Option.  If the President or his or
               -----------------------------------                             
her designee reasonably believes that an Optionee has committed an act of
misconduct, the President may suspend the Optionee's right to exercise any
option pending a determination by the Board of Directors (excluding the Outside
Director accused of such misconduct).  If the Board of Directors (excluding the
Outside Director accused of such misconduct) determines an Optionee has
committed an act of embezzlement, fraud, dishonesty, nonpayment of an obligation
owed to the Company, breach of fiduciary duty or deliberate disregard of the
Company rules resulting in loss, damage or injury to the Company, or if an
Optionee makes an unauthorized disclosure of any Company trade secret or
confidential information, engages in any conduct constituting unfair
competition, induces any Company customer to breach a contract with the Company
or induces any principal for whom the Company acts as agent to terminate such
agency relationship, neither the Optionee nor his or her estate shall be
entitled to exercise any option whatsoever.  In making such determination, the
Board of Directors (excluding the Outside Director accused of such misconduct)
shall act fairly and shall give the Optionee an opportunity to appear and
present evidence on Optionee's behalf at a hearing before the Board or a
committee of the Board.

     5.   Eligibility.  Options may be granted only to Outside Directors.  All
          -----------                                                         
Options shall be automatically granted in accordance with the terms set forth in
Section 4(b) hereof.

          The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director, nor
shall it interfere in any way with any rights which the Director or the Company
may have to terminate his or her directorship at any time.

     6.   Term of Plan; Effective Date.  The Plan shall become effective on the
          ----------------------------                                         
effectiveness of the registration statement under the Securities Act of 1933, as
amended, relating to the Company's initial public offering of securities.  It
shall continue in effect for a term of ten (10) years unless sooner terminated
under Section 13 of the Plan.

     7.   Term of Option.  The term of each Option shall be ten (10) years from
          --------------                                                       
the date of grant thereof.

     8.   Exercise Price and Consideration.
          -------------------------------- 

          (a)  Exercise Price. The per Share exercise price for the Shares to be
               --------------
issued pursuant to exercise of an Option shall be 100% of the fair market value
per Share on the date of grant of the Option.

          (b)  Fair Market Value.  The fair market value shall be determined by
               -----------------                                               
the Board in its discretion; provided, however, that where there is a public
market for the Common Stock, the

                                      -4-
<PAGE>
 
fair market value per Share shall be the mean of the bid and asked prices of the
Common Stock in the over-the-counter market on the date of grant, as reported in
The Wall Street Journal (or, if not so reported, as otherwise reported by the
National Association of Securities Dealers Automated Quotation ("NASDAQ" System)
or, in the event the Common Stock is traded on the NASDAQ National Market or
listed on a stock exchange, the fair market value per Share shall be the closing
price on such system or exchange on the date of grant of the Option (or, in the
event that the Common Stock is not traded on such date, on the immediately
preceding trading date), as reported in The Wall Street Journal. With respect to
any Options granted hereunder concurrently with the initial effectiveness of the
Plan, the fair market value shall be the Price to Public as set forth in the
final prospectus relating to such initial public offering.

          (c)  Form of Consideration.  The consideration to be paid for the
               ---------------------                                       
Shares to be issued upon exercise of an Option shall consist entirely of cash,
check, other Shares of Common Stock having a fair market value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised (which, if acquired from the Company, shall have been
held for at least six months), or any combination of such methods of payment
and/or any other consideration or method of payment as shall be permitted under
applicable corporate law.

     9.   Exercise of Option.
          ------------------ 

          (a)  Procedure for Exercise; Rights as a Shareholder.  Any Option
               -----------------------------------------------             
granted hereunder shall be exercisable at such times as are set forth in Section
4(b) hereof; provided, however, that no Options shall be exercisable prior to
shareholder approval of the Plan in accordance with Section 17 hereof has been
obtained.

               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may consist of any consideration and method of payment
allowable under Section 8(c) of the Plan. Until the issuance (as evidenced by
the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company) of the stock certificate evidencing such Shares,
no right to vote or receive dividends or any other rights as a shareholder shall
exist with respect to the Optioned Stock, notwithstanding the exercise of the
Option. A share certificate for the number of Shares so acquired shall be issued
to the Optionee as soon as practicable after exercise of the Option. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

               Exercise of an Option in any manner shall result in a decrease in
the number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

                                      -5-
<PAGE>
 
          (b)  Termination of Status as a Director.  If an Outside Director
               -----------------------------------                         
ceases to serve as a Director, he or she may, but only within ninety (90) days
after the date he or she ceases to be a Director of the Company, exercise his or
her Option to the extent that he or she was entitled to exercise it at the date
of such termination.  Notwithstanding the foregoing, in no event may the Option
be exercised after its term set forth in Section 7 has expired.  To the extent
that such Outside Director was not entitled to exercise an Option at the date of
such termination, or does not exercise such Option (which he or she was entitled
to exercise) within the time specified herein, the Option shall terminate.

          (c)  Disability of Optionee. Notwithstanding the provisions of Section
               ----------------------
9(b) above, in the event a Director is unable to continue his or her service as
a Director with the Company as a result of his or her total and permanent
disability (as defined in Section 22(e)(3) of the Internal Revenue Code), he or
she may, but only within six (6) months from the date of such termination,
exercise his or her Option to the extent he or she was entitled to exercise it
at the date of such termination.  Notwithstanding the foregoing, in no event may
the Option be exercised after its term set forth in Section 7 has expired.  To
the extent that he or she was not entitled to exercise the Option at the date of
termination, or if he or she does not exercise such Option (which he or she was
entitled to exercise) within the time specified herein, the Option shall
terminate.

          (d)  Death of Optionee.  In the event of the death of an Optionee:
               -----------------                                            

               (i)   During the term of the Option who is, at the time of his or
her death, a Director of the Company and who shall have been in Continuous
Status as a Director since the date of grant of the Option, the Option may be
exercised, at any time within six (6) months following the date of death, by the
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
would have accrued had the Optionee continued living and remained in Continuous
Status as Director for six (6) months after the date of death. Notwithstanding
the foregoing, in no event may the Option be exercised after its term set forth
in Section 7 has expired.

               (ii)  Within three (3) months after the termination of Continuous
Status as a Director, the Option may be exercised, at any time within six (6)
months following the date of death, by the Optionee's estate or by a person who
acquired the right to exercise the Option by bequest or inheritance, but only to
the extent of the right to exercise that had accrued at the date of termination.
Notwithstanding the foregoing, in no event may the option be exercised after its
term set forth in Section 7 has expired.

     10.  Nontransferability of Options.  The Option may not be sold, pledged,
          -----------------------------                                       
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution or pursuant to a qualified
domestic relations order (as defined by the Code or the rules thereunder).  The
designation of a beneficiary by an Optionee does not constitute a transfer.  An
Option may be exercised during the lifetime of an Optionee only by the Optionee
or a transferee permitted by this Section.

     11.  Adjustments Upon Changes in Capitalization; Corporate Transactions.
          ------------------------------------------------------------------ 

          (a)  Adjustments.  Subject to any required action by the shareholders
               -----------                                                     
of the Company, the number of shares of Common Stock covered by each outstanding
Option, the number of shares of Common Stock which have been authorized for
issuance under the Plan but as to which no Options have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option, and the number of shares of Common Stock to be granted under the
provisions set forth in Section 4 of the Plan, as well as the price per share of
Common Stock covered by each such outstanding Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

          (b)  Corporate Transactions.  In the event of (i) a dissolution or
               ----------------------                                       
liquidation of the Company, (ii) a sale of all or substantially all of the
Company's assets, (iii) a merger or consolidation in which the Company is not
the surviving corporation, or (iv) any other capital reorganization in which
more than fifty percent (50%) of the shares of the Company entitled to vote are
exchanged, the Company shall give to the Optionee, at the time of adoption of
the plan for liquidation, dissolution, sale, merger, consolidation or
reorganization, either a reasonable time thereafter within which to exercise the
Option, including Shares as to which the Option would not be otherwise
exercisable, prior to the effectiveness of such liquidation, dissolution, sale,
merger, consolidation or reorganization, at the end of which time the Option
shall terminate, or the right to exercise the Option, including Shares as to
which the Option would not be otherwise exercisable (or receive a substitute
option with comparable terms), as to an equivalent number of shares of stock of
the corporation succeeding the Company or acquiring its business by reason of
such liquidation, dissolution, sale, merger, consolidation or reorganization.

     12.  Time of Granting Options.  The date of grant of an Option shall, for
          ------------------------                                            
all purposes, be the date determined in accordance with Section 4(b) hereof.
Notice of the determination shall be given to each Outside Director to whom an
Option is so granted within a reasonable time after the date of such grant.

     13.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a)  Amendment and Termination.  The Board may amend or terminate the
               -------------------------                                       
Plan from time to time in such respects as the Board may deem advisable;
provided that, to the extent necessary and desirable to comply with Rule 16b-3
under the Exchange Act (or any other applicable law or regulation), the Company
shall obtain approval of the shareholders of the Company to Plan amendments to
the extent and in the manner required by such law or regulation.

                                      -7-
<PAGE>
 
Notwithstanding the foregoing, the provisions set forth in Section 4 of this
Plan (and any other Sections of this Plan that affect the formula award terms
required to be specified in this Plan by Rule 16b-3) shall not be amended more
than once every six months, other than to comport with changes in the Code, the
Employee Retirement Income Security Act of 1974, as amended, or the rules
thereunder.

          (b)  Effect of Amendment or Termination.  Any such amendment or
               ----------------------------------                        
termination of the Plan that would impair the rights of any Optionee shall not
affect Options already granted to such Optionee and such Options shall remain in
full force and effect as if this Plan had not been amended or terminated, unless
mutually agreed otherwise between the Optionee and the Board, which agreement
must be in writing and signed by the Optionee and the Company.

     14.  Conditions Upon Issuance of Shares.  Shares shall not be issued
          ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, state securities laws, and the requirements of any stock exchange
upon which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.  As a
condition to the exercise of an Option, the Company may require the person
exercising such Option to represent and warrant at the time of any such exercise
that the Shares are being purchased only for investment and without any present
intention to sell or distribute such Shares, if, in the opinion of counsel for
the Company, such a representation is required by any of the aforementioned
relevant provisions of law.

     15.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------                                             
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.  Inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

     16.  Option Agreement.  Options shall be evidenced by written option
          ----------------                                               
agreements in such form as the Board shall approve.

     17.  Shareholder Approval.  Continuance of the Plan shall be subject to
          --------------------                                              
approval by the shareholders of the Company at or prior to the first annual
meeting of shareholders held subsequent to the granting of an Option hereunder.
If such shareholder approval is obtained at a duly held shareholders' meeting,
it may be obtained by the affirmative vote of the holders of a majority of the
outstanding shares of the Company present or represented and entitled to vote
thereon.  If such shareholder approval is obtained by written consent, it may be
obtained by the written consent of the holders of a majority of the outstanding
shares of the Company.  Options may be granted, but not exercised before such
shareholder approval.

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


     1.   GRANT OF OPTION.  The Board of Directors of the Company hereby grants
          ---------------

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

                                                                    --------

Option Plan (the "Plan"), which is incorporated herein by reference.
                  ----                                              
(Capitalized terms not defined herein shall have the meanings ascribed to such
terms in the Plan.) In the event of a conflict between the terms and conditions
of the Plan and the terms and conditions of this Nonstatutory Stock Option
Agreement, the terms and conditions of the Plan shall prevail.

     2.   EXERCISE OF OPTION.
          ------------------ 

          (a) RIGHT TO EXERCISE.  This Option is exercisable during its term in
              -----------------                                                
accordance with the Vesting Schedule set out in the Notice of Stock Option Grant
and the applicable provisions of the Plan and this Nonstatutory Stock Option
Agreement.  In the event of Optionee's death, disability or other termination of
Optionee's employment or consulting relationship, the exercisability of the
Option is governed by the applicable provisions of the Plan and this
Nonstatutory Stock Option Agreement.

          (b) METHOD OF EXERCISE.  This Option is exercisable by delivery of an
              ------------------                                               
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
                                         ---------       ---------------   
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
                                                     ----------------       
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan.  The Exercise Notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The Exercise Notice shall be accompanied by payment
of the aggregate Exercise Price as to all Exercised Shares.  This Option shall
be deemed to be exercised upon receipt by the Company of such fully executed
Exercise Notice accompanied by such aggregate Exercise Price.

          No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with all relevant provisions of law
and the requirements of any stock exchange or quotation service upon which the
Shares are then listed.  Assuming such compliance, for income tax purposes the
Exercised Shares shall be considered transferred to the Optionee on the date the
Option is exercised with respect to such Exercised Shares.

     3.   METHOD OF PAYMENT.  Payment of the aggregate Exercise Price shall be 
          -----------------
any of the following, or a combination thereof, at the election of the Optionee:

          (a)  cash;

<PAGE>
 
          (b) check;

          (c) delivery of a properly executed exercise notice together with such
other documentation as the Administrator and the broker, if applicable, shall
require to effect an exercise of the Option and delivery to the Company of the
sale or loan proceeds required to pay the exercise price; or

          (d) surrender of other Shares which (i) in the case of Shares acquired
upon exercise of an option, have been owned by the Optionee for more than six
(6) months on the date of surrender, and (ii) have a Fair Market Value on the
date of surrender equal to the aggregate Exercise Price of the Exercised Shares.

     4.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
          -----------------------------                                        
any manner otherwise than by will or by the laws of descent or distribution or
pursuant to a domestic relations order (as defined by the Code or the rules
thereunder) and may be exercised during the lifetime of Optionee only by the
Optionee or a transferee permitted by Section 10 of the Plan.  The terms of the
Plan and this Nonstatutory Stock Option Agreement shall be binding upon the
executors, administrators, heirs, successors and assigns of the Optionee.

     5.   TERM OF OPTION.  This Option may be exercised only within the term set
          --------------                                                        
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the Plan and the terms of this Nonstatutory Stock Option
Agreement.

     6.   TAX CONSEQUENCES.  Set forth below is a brief summary of certain
          ----------------                                                
federal and California tax consequences relating to this Option under the law in
effect as of the date of grant.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT HIS OR
HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a) EXERCISING THE OPTION.  Since this Option does not qualify as an
              ---------------------                                           
incentive stock option under Section 422 of the Code, the Optionee may incur
regular federal and California income tax liability upon exercise.  The Optionee
will be treated as having received compensation income (taxable at ordinary
income tax rates) equal to the excess, if any, of the fair market value of the
Exercised Shares on the date of exercise over their aggregate Exercise Price.

          (b) DISPOSITION OF SHARES.  If the Optionee holds the Option Shares
              ---------------------                                          
for more than one year, gain realized on disposition of the Shares will be
treated as long-term capital gain for federal and California income tax
purposes.

<PAGE>

     By your signature and the signature of the Company's representative below,
you and the Company agree that this Option is granted under and governed by the
terms and conditions of the Plan and this Nonstatutory Stock Option Agreement.
Optionee has reviewed the Plan and this Nonstatutory Stock Option Agreement in
their entirety, has had an opportunity to obtain the advice of counsel prior to
executing this Nonstatutory Stock Option Agreement and fully understands all
provisions of the Plan and Nonstatutory Stock Option Agreement. Optionee hereby
agrees to accept as binding, conclusive and final all decisions or
interpretations of the Administrator upon any questions relating to the Plan and
Nonstatutory Stock Option Agreement.

Designator. This Agreement will apply to additional Services by agreement of the
parties without the necessity of signing a contract amendment.

     2.   TERM.  This Agreement will commence on the above Contract Effective
          ----                                                     
Date and will expire [*] thereafter. Locations may not be added to this
Agreement without Apollo's prior written consent. The term of this Agreement for
any approved added Location will commence on the first day of the month in which
Services commence and expire [*] thereafter. Notwithstanding anything to the
contrary in this Agreement, provisions which by their nature and intent should
survive its expiration or termination, including, but not limited to, those
relating to confidentiality, liquidated damages, Software license restrictions,
and risk of loss, shall so survive.

     3.   CHARGES; PRODUCTIVITY PROGRAM.  Subscriber will pay to Apollo all
          -----------------------------                                    
charges (plus taxes and other governmental assessments directly applicable to
the provision of Services by Apollo) assessed by Apollo in accordance with this
Agreement; provided, however, the Monthly Fixed Charges specified on each
Services Designator are subject to the following productivity program:

          A.   Commencing on the Contract Effective Date and continuing for 0
months ("Discount Months"), a 100% discount shall apply to Subscriber's Monthly
Fixed Charges.

          B.   Thereafter, each month Apollo will calculate Subscriber's average
Monthly Fixed Charges during the prior 12 months ("Average Monthly Fixed
Charge") and will multiply such Average Monthly Fixed Charge by [*]. The
product thereof will equal Subscriber's booking target ("Target Bookings");
provided, however, in no event will the Target Bookings be less than [*].

          C.   Each month Apollo will also calculate the monthly average number
of Apollo Bookings made by Subscriber during the prior 12 months ("Average
Bookings"). If Subscriber's Average Bookings meet or exceed its Target Bookings
as calculated in accordance with paragraph B above, and Subscriber is meeting
all of its obligations under the Agreement, Apollo will apply a 100% discount to
Subscriber's Monthly Fixed Charges for the prior month. If Subscriber's Average
Bookings are less than its Target Bookings, then Subscriber will pay Apollo a
fee for the prior month equal to $[*] ("Shortfall Fee") multiplied by the
difference between the Average Bookings and the Target Bookings.

          D.   Where calculations are performed less than 12 months after the
Contract Effective Date, they will be based on the months that have elapsed
since the Contract Effective Date. The calculations hereunder will be based
solely on Apollo's records.

By signing below, the parties acknowledge their acceptance of the terms and
conditions of this Agreement and its attachments.

same to any lien or encumbrance. Subscriber accepts full responsibility for loss
or damage to the Services and, in the event thereof, Subscriber must pay Apollo
the insurance value therefor as specified on the Services Designator.

     7.   THIRD PARTY PRODUCTS.  Any product not provided by Apollo ("Third 
          --------------------                                             
Party Product") which sends Transactions to or interfaces with Apollo Services

profile.  Apollo shall have no liability whatsoever with respect to Third Party
Products and Subscriber shall indemnify and hold harmless Apollo for all claims

Subscriber hereby waives and releases Apollo, its owners, officers, directors,
employees, agents, successors and assigns from all obligations and liabilities
and all rights, claims and remedies of Subscriber against them, express or
implied, arising by law or otherwise, due to any defects, errors, malfunctions,
performance, failure to perform, or use of the Services, or any part thereof, or
for interruptions of service, including any liability or claim in tort, for acts
of Apollo's subcontractors, or for loss of revenue, profits or data, or any
other direct, indirect, incidental, special or consequential damages.

     10.  TERMINATION FOR CAUSE.
          ---------------------

          A.   If either party (the "Defaulting Party") becomes insolvent; if
the other party (the "Insecure Party") has evidence that the Defaulting Party is
not paying its bills when due without just cause; if a receiver of the
Defaulting Party's assets is appointed; if the Defaulting Party takes any step
leading to its cessation as a going concern; or if the Defaulting Party ceases
to do business or otherwise ceases or suspends operations for reasons other than
an event of force majeure, then the Insecure Party may immediately terminate
this Agreement on written notice to the Defaulting Party or may require that
certain conditions are met in order to avoid such termination.
<PAGE>
 
          B.   If Subscriber fails to perform or observe any of its obligations
hereunder, and such failure continues for a period of five business days after
written notice to Subscriber (except in any circumstance where a cure is
impossible in which case there shall be no cure period), then without prejudice
to any other rights or remedies of Apollo, including the right to recover
liquidated damages, all or any of the rights of Subscriber under this Agreement
shall, at the option of Apollo, be terminated, reduced or restricted.

          C.   If Apollo terminates this Agreement for cause, or if Subscriber
terminates this Agreement other than for cause, then Subscriber shall pay to
Apollo all amounts of promotional support as specified on each Services
Designator, and Subscriber shall reimburse Apollo for any charges waived or
discounted by Apollo prior to the termination.

     11.  INDEMNIFICATION.  Subscriber shall indemnify and hold harmless Apollo,
          ---------------                                               
its owners, officers, directors, employees, agents, successors and assigns,
against and from any and all liabilities, damages, losses, expenses, claims,
demands, suits, fines or judgments, including reasonable attorneys' fees, costs
and expenses incident thereto, which may be incurred by Apollo by reason of any
loss, damage, or destruction of property, including loss of use thereof, whether
in contract or tort, law or equity, arising out of or in connection with any
act, failure to act, error or omission of Subscriber, its owners, officers,
directors, employees or agents in the performance or failure of performance of
its obligations under this Agreement.

     12.  LIQUIDATED DAMAGES.  If Apollo terminates this Agreement for cause,
          ------------------                                          
or if Subscriber terminates this Agreement other than for cause, then Subscriber

proprietary and confidential information of Apollo, including, but not limited
to, the provisions of this Agreement; provided, however, either party may share
the terms of this Agreement with its accountant and attorney strictly on a need-
to-know basis. Subscriber shall not use the name, logo or product names of
Apollo in brochures, proposals, contracts or other publicly disseminated
materials without first securing Apollo's written approval.

     14.  GOVERNING LAW; JURISDICTION.  This Agreement and any disputes arising
          ---------------------------

          -------------------                                           
the prior written consent of Apollo, which consent shall not be unreasonably
withheld. In the event Subscriber sells substantially all of its assets, but
