ITEM 17. UNDERTAKINGS
 
  The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  Insofar as indemnification for liabilities arising under the Securities Act,
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the Delaware General Corporation Law, the Registrant's
Restated Certificate of Incorporation, the Registrant's Bylaws, the
Registrant's indemnification agreements or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act,
and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of Prospectus shall
  be deemed to be a new Registration Statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

<PAGE>
 
imprinted with a legend in the following form (in addition to any
legend required under applicable state securities laws):

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
          INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933.  SUCH SHARES MAY NOT BE SOLD, TRANSFERRED OR PLEDGED IN THE
          ABSENCE OF SUCH REGISTRATION OR UNLESS THE COMPANY RECEIVES AN OPINION
          OF COUNSEL (WHICH MAY BE COUNSEL FOR THE COMPANY) REASONABLY
          ACCEPTABLE TO IT STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE
          REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT."

          "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
          ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE
          SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE
          COMPANY.  THIS CONDITION TO TRANSFER SHALL TERMINATE ON THE EFFECTIVE
          DATE OF THE COMPANY'S INITIAL PUBLIC OFFERING."

          Each Investor and Holder consents to the Company making a notation on
its records and giving instructions to any transfer agent of the Restricted
Securities in order to implement the restrictions on transfer established in
this Section 1.

      1.4 Notice of Proposed Transfers.  The holder of each certificate
          ----------------------------                                 
representing Restricted Securities, by acceptance thereof, agrees to comply in
all respects with the provisions of this Section 1.  Prior to any proposed sale,
assignment, transfer or pledge of any Restricted Securities, unless there is in
effect a registration statement under the Securities Act covering the proposed
transfer, the holder thereof shall give written notice to the Company of such
holder's intention to effect such transfer, sale, assignment or pledge.  Each
such notice shall describe the manner and circumstances of the proposed
transfer, sale, assignment or pledge in sufficient detail, and shall be
accompanied at such holder's expense by either (i) a written opinion of legal
counsel who shall, and whose legal opinion shall be, reasonably satisfactory to
the Company, addressed to the Company, to the effect that the proposed transfer
of the Restricted Securities may be effected without registration under the
Securities Act, or (ii) a "no action" letter from the Commission to the effect
that the transfer of such securities without registration will not result in a
recommendation by the staff of the Commission that action be taken with respect
thereto, or (iii) any other evidence reasonably satisfactory to counsel to the
Company, whereupon the holder of such Restricted Securities shall be entitled to
transfer such Restricted Securities in accordance with the terms of the notice
delivered by the holder to the Company.  The Company will not require such a
legal opinion or "no action" letter (a) in any transaction in compliance with
Rule 144, (b) in any transaction in which an Investor which is a corporation
distributes Restricted Securities after six (6) months after the purchase
thereof solely to its majority owned subsidiaries or affiliates for no
consideration, or (c) in any transaction in which 

                                      -4-
<PAGE>
 
an Investor which is a partnership distributes Restricted Securities after six
(6) months after the purchase thereof solely to partners thereof for no
consideration; provided that each transferee agrees in writing to be subject to
               --------     
the terms of this Section 1.4. Each certificate evidencing the Restricted
Securities transferred as above provided shall bear, except if such transfer is
made pursuant to Rule 144, the appropriate restrictive legend set forth in
Section 1.3 above, except that such certificate shall not bear such restrictive
legend if, in the opinion of counsel for such holder and the Company, such
legend is not required in order to establish compliance with any provisions of
the Securities Act.

      1.5 Requested Registration.
          ---------------------- 

          (a) Request for Registration.  In case the Company shall receive from
              ------------------------                                         
Initiating Holders a written request that the Company effect any registration,
qualification or compliance with respect to the Registrable Securities, the
Company will:

               (i)  promptly give written notice of the proposed registration,
qualification or compliance to all other Holders; and

              (ii) as soon as practicable, use its best efforts to effect such
registration, qualification or compliance (including, without limitation, the
execution of an undertaking to file post-effective amendments, appropriate
qualification under applicable blue sky or other state securities laws and
appropriate compliance with applicable regulations issued under the Securities
Act and any other governmental requirements or regulations) as may be so
requested and as would permit or facilitate the sale and distribution of all or
such portion of such Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or
Holders joining in such request as are specified in a written request received
by the Company within thirty (30) days after receipt of such written notice from
the Company; provided, however, that the Company shall not be obligated to take
             --------  -------                                                 
any action to effect any such registration, qualification or compliance pursuant
to this Section 1.5:

                   (1) In any particular jurisdiction in which the Company would
be required to execute a general consent to service of process in effecting such
registration, qualification or compliance unless the Company is already subject
to service in such jurisdiction and except as may be required by the Securities
Act;

                   (2) Prior to the earlier of (a) six (6) months following the
effective date of the first public offering of the Common Stock of the Company
to the general public which is effected pursuant to a registration statement
filed with, and declared effective by, the Commission under the Securities Act
(the "Initial Public Offering") or (b) July 19, 2001;

                   (3) During the period starting with the date sixty (60) days
prior to the Company's estimated date of filing of, and ending on the date six
(6) months immediately following the effective date of, any registration
statement pertaining to securities of the Company (other than a registration of
securities in a Rule 145 transaction or with respect to an employee 

                                      -5-
<PAGE>
 
benefit plan), provided that the Company is actively employing in good faith all
reasonable efforts to cause such registration statement to become effective and
that the Company's estimate of the date of filing such registration statement is
made in good faith;

                   (4) After the Company has effected two (2) such registrations
pursuant to this subparagraph 1.5(a), each such registration has been declared
or ordered effective and the securities offered pursuant to each such
registration have been sold; or

                   (5) If the Company shall furnish to such Holders a
certificate, signed by the President of the Company, stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company or its shareholders for a registration statement to be filed in the
near future, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 1.5 shall be deferred for a period not to
exceed ninety (90) days from the date of receipt of written request from the
Initiating Holders; provided, however, that the Company may not utilize this
right more than once in any twelve (12) month period.

     Subject to the foregoing clauses (1) through (5), the Company shall file a
registration statement covering the Registrable Securities so requested to be
registered as soon as practicable after receipt of the request or requests of
the Initiating Holders.

          (b) Underwriting.  In the event that a registration pursuant to
              ------------                                               
Section 1.5 is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the notice given pursuant to
Section 1.5(a)(i).  The right of any Holder to registration pursuant to Section
1.5 shall be conditioned upon such Holder's participation in the underwriting
arrangements required by this Section 1.5 and the inclusion of such Holder's
Registrable Securities in the under  writing, to the extent requested, to the
extent provided herein.

     The Company shall (together with all Holders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form with the managing underwriter selected for such underwriting by a
majority in interest of the Initiating Holders (which managing underwriter shall
be reasonably acceptable to the Company).  Notwithstanding any other provision
of this Section 1.5, if the managing underwriter advises the Initiating Holders
in writing that marketing factors require a limitation of the number of shares
to be underwritten, then the Company shall so advise all Holders of Registrable
Securities and the number of shares of Registrable Securities that may be
included in the registration and underwriting shall be allocated among all
Holders thereof in proportion, as nearly as practicable, to the respective
amounts of Registrable Securities held by such Holders at the time of filing the
registration statement, provided, however, that the number of shares of
                        --------  -------                              
Registrable Securities to be included in such underwriting shall not be reduced
unless all other securities are first entirely excluded from the underwriting.
No Registrable Securities excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such registration.  To
facilitate the allocation of shares in accordance with the above provisions, the
Company or the underwriters may round the number of shares allocated to any
Holder to the nearest 100 shares.

                                      -6-
<PAGE>
 
     If any Holder of Registrable Securities disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, the managing underwriter and the Initiating Holders.  The
Registrable Securities and/or other securities so withdrawn shall also be
withdrawn from registration, and such Registrable Securities shall not be
transferred in a public distribution prior to ninety (90) days after the
effective date of such registration.

      1.6 Company Registration.
          -------------------- 

          (a) Notice of Registration.  If at any time or from time to time, the
              ----------------------                                           
Company shall determine to register any of its securities, either for its own
account or the account of a security holder or holders other than (i) a
registration relating solely to employee benefit plans, or (ii) a registration
relating solely to a Commission Rule 145 transaction, the Company will:

              (i)  promptly give to each Holder written notice thereof; and

              (ii) include in such registration (and any related qualification
under blue sky laws or other compliance), and in any underwriting involved
therein, all the Registrable Securities specified in a written request or
requests made within thirty (30) days after receipt of such written notice from
the Company by any Holder, but only to the extent that such inclusion will not
diminish the number of securities included by holders of the Company's
securities who have demanded such registration pursuant to Section 1.5 hereof.

          (b) Underwriting.  If the registration of which the Company gives
              ------------                                                 
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 1.6(a)(i).  In such event, the right of any Holder to
registration pursuant to Section 1.6 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein.  All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company (or by the
holders who have demanded such registration).  Notwithstanding any other
provision of this Section 1.6, if the managing underwriter determines that
marketing factors require a limitation of the number of shares to be
underwritten, the managing underwriter may limit the number of Registrable
Securities to be included in the registration and underwriting (up to the
exclusion of all Registrable Securities in the event of the Company's Initial
Public Offering), on a pro rata basis based on the total number of securities
                       --- ----                                              
(including, without limitation, Registrable Securities) entitled to registration
pursuant to registration rights granted to the participating Holders by the
Company; provided, however, that if such offering is not the Initial Public
Offering, no such reduction may reduce the number of securities being sold by
the Holders to less than thirty percent (30%) of the shares being sold in such
offering.  To facilitate the allocation of shares in accordance with the above
provisions, the Company or the underwriters may round the number of shares
allocated to any Holder or other holder to the nearest 100 shares.  If any
Holder or other holder disapproves of the terms of any such underwriting, he or
she may elect to withdraw therefrom by written notice to the Company and the
managing underwriter.  Any securities excluded 

                                      -7-
<PAGE>
 
or withdrawn from such underwriting shall be withdrawn from such registration,
and shall not be transferred in a public distribution prior to ninety (90) days
after the effective date of the registration statement relating thereto.

          (c) Right to Terminate Registration.  The Company shall have the right
              -------------------------------                                   
to terminate or withdraw any registration initiated by it under this Section 1.6
prior to the effectiveness of such registration, whether or not any Holder has
elected to include securities in such registration.

      1.7 Registration on Form S-3.
          ------------------------ 

          (a) Following the Initial Public Offering, the Company shall use its
best efforts to become eligible to use the Form S-3 registration statement for
public offerings of its capital stock.  If any Holder or Holders of Registrable
Securities requests that the Company file a registration statement on Form S-3
(or any successor form to Form S-3) for a public offering of shares of the
Registrable Securities, the reasonably anticipated aggregate price to the public
of which, net of underwriting discounts and commissions, would exceed $500,000,
and the Company is a registrant entitled to use Form S-3 to register the
Registrable Securities for such an offering, the Company shall use its best
efforts to cause such Registrable Securities to be registered for the offering
on such form. The Company will (i) promptly give written notice of the proposed
registration to all other Holders, and (ii) as soon as practicable, use its best
efforts to effect such registration (including, without limitation, the
execution of an undertaking to file post-effective amendments, appropriate
qualification under applicable blue sky or other state securities laws and
appropriate compliance with applicable regulations issued under the Securities
Act and any other governmental requirements or regulations) as may be so
requested and as would permit or facilitate the sale and distribution of all or
such portion of such Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or
Holders joining in such request as are specified in a written request received
by the Company within thirty (30) days after receipt of such written notice from
the Company.  The substantive provisions of Section 1.5(b) shall be applicable
to each registration initiated under this Section 1.7.

          (b) Notwithstanding the foregoing, the Company shall not be obligated
to take any action pursuant to this Section 1.7:  (i) in any particular
jurisdiction in which the Company would be required to execute a general consent
to service of process in effecting such registration, qualification or
compliance unless the Company is already subject to service in such jurisdiction
and except as may be required by the Securities Act; (ii) during the period
starting with the date sixty (60) days prior to the Company's estimated date of
filing of, and ending on the date four (4) months immediately following the
effective date of, a registration statement (other than with respect to a
registration statement relating to a Rule 145 transaction, an offering solely to
employees or any other registration which is not appropriate for the
registration of Registrable Securities), provided that the Company is actively
employing in good faith all reasonable efforts to cause such registration
statement to become effective; (iii) during any 12-month period in which the
Company has effected at least three (3) such registrations pursuant to this
Section 1.6 or Section 1.7 of the Prior Agreement; or (iv) if the Company shall
furnish to such Holder a certificate signed by the President of the Company
stating that, in the good faith judgment of the Board of Directors, it would be
seriously detrimental to the 

                                      -8-
<PAGE>
 
Company or its shareholders for registration statements to be filed in the near
future, then the Company's obligation to use its best efforts to file a
registration statement shall be deferred for a period not to exceed ninety (90)
days from the receipt of the request to file such registration by such Holder or
Holders; provided, however, that the Company may not utilize this right more
than once in any twelve (12) month period.

      1.8  Limitations on Subsequent Registration Rights.  From and after the
           ---------------------------------------------                     
date hereof, the Company shall not enter into any agreement granting any holder
or prospective holder of any securities of the Company registration rights with
respect to such securities unless such new registration rights are subordinate
to the registration rights granted Holders hereunder, including, without
limitation, provision for a standoff obligation no shorter than that provided
for in this Agreement.

      1.9  Expenses of Registration.  All Registration Expenses incurred in
           ------------------------                                        
connection with any registration pursuant to Sections 1.5, 1.6 and 1.7 and the
reasonable cost of one special legal counsel to represent all of the Holders
together in any such registration shall be borne by the Company.  If a
registration proceeding is begun upon the request of Initiating Holders pursuant
to Section 1.5, but such request is subsequently withdrawn, then the Holders of
Registrable Securities to have been registered may either:  (i) bear all
Registration Expenses of such proceeding, pro rata on the basis of the number of
shares to have been registered, in which case the Company shall be deemed not to
have effected a registration pursuant to subparagraph 1.5(a) of this Agreement;
or (ii) require the Company to bear all Registration Expenses of such
proceeding, in which case the Company shall be deemed to have effected a
registration pursuant to subparagraph 1.5(a) of this Agreement.  Notwith
standing the foregoing, however, if at the time of the withdrawal, the Holders
have learned of a material adverse change in the condition, business or
prospects of the Company from that known to the Holders at the time of their
request, then the Holders shall not be required to pay any of said Registration
Expenses.  In such case, the Company shall be deemed not to have effected a
registration pursuant to subparagraph 1.5(a) of this Agreement.  Unless
otherwise stated, all other Selling Expenses relating to securities registered
on behalf of the Holders shall be borne by the Holders of the registered
securities included in such registration pro rata on the basis of the number of
shares so registered.

      1.10 Registration Procedures.  In the case of each registration,
           -----------------------                                    
qualification or compliance effected by the Company pursuant to this Section 1,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof.  At its expense the Company will:

           (a) Prepare and file with the Commission a registration statement
with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least one hundred
eighty (180) days or until the distribution described in the registration
statement has been completed; and

           (b) Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as 

                                      -9-
<PAGE>
 
may be necessary to comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration
statement.

           (c) Furnish to the Holders participating in such registration and to
the under writers of the securities being registered such reasonable number of
copies of the registration statement, preliminary prospectus, final prospectus
and such other documents as such underwriters may reasonably request in order to
facilitate the public offering of such securities.

           (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders;
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act.

           (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

           (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

           (g) Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed.

           (h) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

           (i) Use its best efforts to furnish, at the request of any Holder
requesting registration of Registrable Securities pursuant to this Section 1, on
the date that such Registrable Securities are delivered to the underwriters for
sale in connection with a registration pursuant to this Section 1, if such
securities are being sold through underwriters, or, if such securities are not
being sold through underwriters, on the date that the registration statement
with respect to such securities becomes effective, (i) an opinion, dated such
date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and to
the Holders requesting registration of Registrable Securities and (ii) a letter
dated such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent 

                                     -10-
<PAGE>
 
certified public accountants to underwriters in an underwritten public offering,
addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities.

      1.11 Indemnification.
           --------------- 

           (a) The Company will indemnify each Holder, each of its officers and
directors and partners, and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, with respect to which registration,
qualification or compliance has been effected pursuant to this Section 1, and
each underwriter, if any, and each person who controls any under  writer within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages or liabilities (or actions in respect thereof), including any of
the foregoing incurred in settlement of any litigation, commenced or threatened,
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any registration statement, prospectus, preliminary
prospectus, offering circular or other document, or any amendment or supplement
thereto, incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, or any
violation or any alleged violation by the Company of any rule or regulation
promulgated under the Securities Act or the Exchange Act or any state securities
law applicable to the Company in connection with any such registration,
qualification or compliance, and the Company will reimburse each such Holder,
each of its officers and directors, and each person controlling such Holder,
each such underwriter and each person who controls any such underwriter, for any
legal and any other expenses reasonably incurred in connection with
investigating, preparing or defending any such claim, loss, damage, liability or
action, as such expenses are incurred, provided that the Company will not be
liable in any such case to the extent that any such claim, loss, damage,
liability or expense arises out of or is based on any untrue statement or
omission or alleged untrue statement or omission, made in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder, controlling person or underwriter and stated to be
specifically for use therein.

           (b) Each Holder will, if Registrable Securities held by such Holder
are included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, each of its directors and
officers, each underwriter, if any, of the Company's securities covered by such
a registration statement, each person who controls the Company or such
underwriter within the meaning of Section 15 of the Securities Act, and each
other such Holder, each of its officers and directors and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company, such Holders, such directors, officers, persons, underwriters or
control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, as such expenses are incurred, in each case to the extent,
but only to the 

                                     -11-
<PAGE>
 
extent, that such untrue statement (or alleged untrue statement) or omission (or
alleged omission) is made in such registration statement, prospectus, offering
circular or other document in reliance upon and in conformity with written
information furnished to the Company by an instrument duly executed by such
Holder and stated to be specifically for use therein.

           (c) Each party entitled to indemnification under this Section 1.11
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense; provided, however, that an Indemnified Party (together with all
other Indemnified Parties which may be represented without conflict by one
counsel) shall have the right to retain one separate counsel, with the fees and
expenses to be paid by the Indemnifying Party, if representation of such
Indemnified Party by the counsel retained by the Indemnifying Party would be
inappropriate due to actual or potential differing interests between such
Indemnified Party and any other party represented by such counsel in such
proceeding.  The failure of any Indemnified Party to give notice as provided
herein shall not relieve the Indemnifying Party of its obligations under this
Section 1.11 unless the failure to give such notice is materially prejudicial to
an Indemnifying Party's ability to defend such action.  No Indemnifying Party,
in the defense of any such claim or litigation, shall, except with the consent
of each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation.

      1.12 Information by Holder.  The Holder or Holders of Registrable
           ---------------------                                       
Securities included in any registration shall furnish to the Company such

them and the distribution proposed by such Holder or Holders as the Company may
request in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Section 1.

certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Securities to the public without registration, after such
time as a public market exists for the Common Stock of the Company, the Company
agrees to use its best efforts to:

           (a) Make and keep public information available, as those terms are

the effective date that the Company becomes subject to the reporting
requirements of the Securities Act or the Exchange Act;

           (b) File with the Commission in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act

                                     -12-
<PAGE>
 
           (c) So long as an Investor owns any Restricted Securities, to furnish
to the Investor forthwith upon request a written statement by the Company as to
its compliance with the reporting requirements of said Rule 144 (at any time
after ninety (90) days after the effective date of the Initial Public Offering),
and of the Securities Act and the Exchange Act (at any time after it has become
subject to such reporting requirements), a copy of the most recent annual or
quarterly report of the Company, and such other reports and documents of the
Company and other information in the possession of or reasonably obtainable by
the Company as an Investor may reasonably request in availing itself of any rule
or regulation of the Commission allowing an Investor to sell any such securities
without registration.

connection with any transfer or assignment of Registrable Securities by an
Investor (together with any affiliate); provided that (a) such transfer may
                                        --------

of such assignment is given to the Company, and (c) such transferee or assignee

siblings of such partners or spouses who acquire Registrable Securities by gift,
will or intestate succession) of such Investor, or (ii) acquires from such
Investor at least 100,000 shares of Restricted Securities (as appropriately
adjusted for stock splits and the like).

      1.15 Standoff Agreement.  Each Holder agrees in connection with any
           ------------------                                            
registration of the Company's securities (other than a registration of
securities in a Rule 145 transaction or with respect to an employee benefit
plan), upon request of the Company or the underwriters managing any under
written offering of the Company's securities, not to sell, make any short sale
of, loan, pledge (or otherwise encumber or hypothecate), grant any option for
the purchase of, or otherwise directly or indirectly dispose of any Registrable
Securities (other than those included in the registration) without the prior
written consent of the Company and such managing underwriters for such period of
time, not to exceed 180 days, as the Board of Directors establishes pursuant to
its good faith negotiations with such managing underwriters; provided, however,
                                                             --------  -------

directors of the Company who own stock of the Company shall also be bound by
such restrictions.

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

      2.6 Termination of Covenants.  The covenants set forth in Sections 2.1
          ------------------------                                          
through 2.5 shall terminate on, and be of no further force or effect after, the
closing of the Company's Initial Public Offering.

      2.7 Right of First Offer.  Subject to the terms and conditions specified
          --------------------                                                
in this Section 2.7, the Company hereby grants to each Investor a right of first
offer with respect to future sales by the Company of its Securities (as
hereinafter defined).

          Each time the Company proposes to offer subsequent to the offering
under the Series E Agreement any shares of, or securities convertible into or
exercisable for any shares of, any class of its capital stock ("Securities"),
the Company shall first make an offering of such Securities to each Investor in
accordance with the following provisions:

          (a) The Company shall deliver a notice by certified mail ("Notice") to
each Investor stating (i) its bona fide intention to offer such Securities, (ii)
the number of such Securities to be offered, (iii) the price, if any, for which
it proposes to offer such Securities, and (iv) the terms of such offer.

          (b) Within fifteen (15) calendar days after receipt of the Notice, the
Investor may elect to purchase or obtain, at the price and on the terms
specified in the Notice, up to an amount of such Securities equal to that
portion of such Securities which equals the proportion that the number of shares
of Common Stock then issued or issuable to the Investor upon conversion of the
shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock, Series D Preferred 

                                     -15-
<PAGE>
 
Stock and Series E Preferred Stock held by the Investor bears to the sum of the
number of shares of Common Stock then issued plus the number of shares of Common
Stock issuable upon conversion of all convertible securities of the Company then
outstanding. For purposes of this Section 2.7, the term "Investor" includes any
general partners or affiliates of an Investor. An Investor shall be entitled to
apportion the right of first offer hereby granted among itself and its partners
and affiliates in such proportions as it deems appropriate.

          (c) If all Securities which the Investors are entitled to purchase
pursuant to this Section 2.7 are not elected to be obtained as provided in
subsection 2.7(b) hereof, the Company may, during the thirty (30) day period
following the expiration of the period provided in subsection 2.7(b) hereof,
offer such unsubscribed Securities to any person or persons at a price not less
than, and upon terms no more favorable to the offeree than, those specified in
the Notice.  If the Company does not enter into an agreement for the sale of the
Securities within such period, or if such agreement is not consummated within
thirty (30) days of the execution thereof, the right provided hereunder shall be
deemed to be revived.

          (d) The right of first offer in this Section 2.7 shall not be
applicable (i) to the issuance or sale of up to 6,000,000 shares of capital

      2.8 Voting Agreement and Grant of Proxy with Respect to Reorganization or
          ---------------------------------------------------------------------
Sale of Assets Transaction.  If a reorganization (as defined in Section 181 of
- --------------------------                                                    
the California Corporations Code) or a transaction in which all or substantially
all of the Company's assets are proposed to be sold (collectively, a
"Reorganization") is proposed to be presented to the shareholders of the Company
for approval, then the Holders agree as follows:

          (a) Agreement to Vote in Accordance with Preliminary Vote; Grant of
              ---------------------------------------------------------------
Proxy. Not less than 12 business days prior to the date a vote is to be taken by
- -----                                                                           
(or written consent to be mailed to) the shareholders of the Company with
respect to a Reorganization, the Secretary of the Company (the "Secretary")
shall send via overnight courier or facsimile transmission to each Holder a
complete description of such Reorganization and a questionnaire (the
"Questionnaire"), to be completed by each Holder and returned to the Secretary,
upon which each Holder shall indicate 

                                     -16-
<PAGE>
 
whether such Holder would approve the Reorganization at a formal vote or written
consent of the shareholders of the Company. Each Holder shall complete the
Questionnaire and return it to the Secretary within 10 business days of the date
the Questionnaire was deemed given in accordance with Section 3.5 hereof. Upon
the earlier of (i) the date the Secretary receives all completed Questionnaires
or (ii) 11 business days after the Questionnaires are deemed given to the
Holders, the Secretary shall tabulate the responses to the Questionnaires. If
the Holders of a majority of the shares of stock represented on the completed
and returned Questionnaires (without regard to how many shares in the aggregate
are held by all Holders) approve the Reorganization (without regard for any
series, class or other voting rights, if any, contained in the Amended and
Restated Articles of Incorporation of the Company from time to time), then each
Holder agrees that, regardless of whether such Holder indicated on the
Questionnaire that such Holder would vote to approve such Reorganization, such
Holder will approve the proposed Reorganization at the time the proposed
Reorganization is formally presented to the shareholders for their approval, and
grants to the Secretary a limited, irrevocable proxy to so vote each Holder's
shares, such proxy to be substantially in the form attached hereto as Exhibit B
                                                                      ---------
and to be executed and delivered to the Secretary at the Closing (as defined in
the Series E Agreement).

          (b) Covenant not to Impede Transaction.  If a majority approval by the
              ----------------------------------                                
Holders who timely return Questionnaires of the proposed Reorganization is
indicated pursuant to the procedure set forth in subsection 2.8(a) above, then
each Holder further agrees not to in any way impede the consummation of the
proposed Reorganization.  This covenant shall include, without limitation, the
obligation not to seek dissenters' appraisal rights or take any other action
that would reasonably be taken (in the discretion of the Company's Board of
Directors after consulting with the Company's counsel and independent public
accountants) to prevent the proposed Reorganization from being eligible to be
accounted for as a pooling of interests.

          (c) Termination of Voting Agreement.  All agreements and covenants set
              -------------------------------                                   
forth in this Section 2.8 shall terminate on, and be of no further force and
effect after, the earlier of (i) the first anniversary of the date of this
Agreement and (ii) the closing of the Initial Public Offering.

the Vesting Commencement Date, and 1/48 of the Shares subject to the Option
shall vest each month thereafter, subject to your remaining in Continuous Status
as an Employee or Consultant as of such vesting dates. Notwithstanding the
foregoing, in the event of a bona fide acquisition of the Company pursuant to a
merger of the Company with or into another business entity (other than a merger
or consolidation which would result in the voting securities of the Company
outstanding immediately prior to the merger continuing to represent (either by

surviving entity) at least fifty percent (50%) of the total voting power
represented by the voting securities of the Company or such surviving entity
outstanding immediately after such merger or consolidation) with or into another
corporation or a sale of all or substantially all of the assets of the Company,
One Hundred percent (100%) of the shares subject to the Option shall become
fully vested and exercisable immediately prior to the effective time thereof.

     This Option may be exercised, to the extent vested, for thirty (30) days
after termination of Optionee's Continuous Status as an Employee or Consultant,
or such longer period as may be applicable upon death or disability of Optionee
as provided in the Plan, but in no event later than the Term/Expiration Date as
provided above.

II.  AGREEMENT
     ---------

     1.   Grant of Option.  PointCast Incorporated (the "Company"), hereby
          ---------------                                                 
grants to the Optionee named in the Notice of Grant (the "Optionee"), an option
(the "Option") to purchase the total number of shares of Common Stock (the
"Shares") set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price") subject to the terms,
definitions and provisions of the 1994 Stock Plan (the "Plan") adopted by the
Company, which is incorporated herein by reference.

          If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an ISO as defined in Section 422
of the Code.  However, if this Option is intended to be an ISO, to the extent
that it exceeds the $100,000 rule of Code Section 422(d) it shall be treated as
a Nonstatutory Stock Option ("NSO").

     2.   Exercise of Option.  This Option shall be exercisable during its term
          ------------------                                                   
in accordance with the provisions of Section 9 of the Plan as follows:

          (i)  Right to Exercise.
               ----------------- 

               (a) Subject to subsections 2(i)(b) through 2(i)(e) below, this
option may be exercised in whole or in part at any time. Vested Shares shall not
be subject to the Company's 

                                      -2-
<PAGE>
 
repurchase right (as set forth in the Restricted Stock Purchase Agreement,
attached hereto as Exhibit C-1).

               (b) As a condition to exercising this Option for unvested Shares,
the Optionee must execute the Restricted Stock Purchase Agreement.

               (c) This Option may not be exercised for a fraction of a Share.

               (d) In the event of Optionee's death, disability or other
termination of the employment or consulting relationship, the exercisability of
the Option is governed by Sections 6, 7 and 8 below, subject to the limitation
contained in subsection 2(i)(e).

               (e) 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 Grant.

          (ii) Method of Exercise.  This Option shall be exercisable by written
               ------------------                                              
notice (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 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, together with an executed copy of the Restricted Stock Purchase Agreement,
if applicable, shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice and Restricted Stock Purchase
Agreement 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 and Restricted Stock Purchase Agreement accompanied by the Exercise
Price.

          No Shares shall 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 the 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, 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 his or her Investment
Representation Statement in the form attached hereto as Exhibit B, and shall
read the applicable rules of the Commissioner of Corporations attached to such
Investment Representation Statement.

     4.  Lock-Up Period.  Optionee hereby agrees that if so requested by the
         --------------                                                     
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or 

                                      -3-
<PAGE>
 
otherwise transfer any Shares or other securities of the Company during the 180-
day period (or such longer period as may be requested in writing by the Managing
Underwriter and agreed to in writing by the Company) (the "Market Standoff
Period") following the effective date of a registration statement of the Company
filed under the Securities Act; provided, however, that such restriction shall
apply only to the first registration statement of the Company to become
effective under the Securities Act that includes securities to be sold on behalf
of the Company to the public in an underwritten public offering under the
Securities Act. The Company may impose stop-transfer instructions with respect
to securities subject to the foregoing restrictions until the end of such Market
Standoff Period.

      5.  Method of Payment.  Payment of the Exercise Price shall be by any of
          -----------------                                                   
the following, or a combination thereof, at the election of the Optionee:

          (i)   cash; or

          (ii)  check; or

          (iii) surrender of other shares of Common Stock of the Company which
(A) in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by the Optionee for more than six (6) months on the date of
surrender, and (B) have a Fair Market Value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

          (iv)  to the extent permitted by the Administrator, 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

          (v)   full recourse promissory note, in the form attached hereto
as Exhibit C-6.

      6.  Restrictions on Exercise.  This Option may not be exercised until 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
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.

      7.  Termination of Relationship.  In the event an Optionee's Continuous
          ---------------------------                                        
Status as an Employee or Consultant terminates, Optionee may, to the extent the
Option was vested at the date of such termination (the "Termination Date"),
exercise this Option during the Termination Period set out in the Notice of
Grant.  To the extent that Optionee was not vested in this Option at the date of
such termination, or if Optionee does not exercise this Option within the time
specified herein, the Option shall terminate.

                                      -4-
<PAGE>
 
      8.  Disability of Optionee.  Notwithstanding the provisions of Section 6
          ----------------------                                              
above, in the event of termination of an Optionee's Continuous Status as an
Employee or Consultant as a result of his or her disability, Optionee may, but
only within twelve (12) months from the date of such termination (and in no
event later than the expiration date of the term of such Option as set forth in
the Stock Option Agreement), exercise the Option to the extent the Option was
vested at the date of such termination; provided, however, that if such
disability is not a "disability" as such term is defined in Section 22(e)(3) of
the Code, in the case of an ISO such ISO shall cease to be treated as an ISO and
shall be treated for tax purposes as an NSO on the ninety-first (91st) day
following such termination.  To the extent that Optionee is not vested in the
Option at the date of termination, or if Optionee does not exercise such Option
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

      9.  Death of Optionee.  In the event of termination of Optionee's
          -----------------                                            
Continuous Status as an Employee or Consultant as a result of the death of
Optionee, the Option may be exercised at any time within twelve (12) 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 acquires the right to exercise the Option by bequest
or inheritance, but only to the extent the Option was vested at the date of
death.  To the extent that Optionee is not vested in the Option at the date of
death, or if the Option is not exercised within the time specified herein, the
Option shall terminate, and the Shares covered by such Option shall revert to
the Plan.

      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 Optionee.  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 be exercised only within the term set
          --------------                                                        
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.

      12. Tax Consequences.  Set forth below is a brief summary as of the date
          ----------------                                                    
of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares.  THIS SUMMARY IS NECESSARILY INCOMPLETE,
AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT
A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (i)   Exercise of ISO.  If this Option qualifies as an ISO, 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 adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.

                                      -5-
<PAGE>
 
          (ii)  Exercise of ISO Following Disability.  If the Optionee's
                ------------------------------------                    
Continuous Status as an Employee or Consultant terminates as a result of
disability that is not total and permanent disability as defined in Section
22(e)(3) of the Code, to the extent permitted on the date of termination, the
Optionee must exercise an ISO within three months of such termination for the
ISO to be qualified as an ISO.

          (iii) Exercise of NSO.  There may be a regular federal income tax
                ---------------                                            
liability upon the exercise of an NSO.  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 Shares on the date of exercise
over the Exercise Price.  If Optionee is an Employee, 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.  If the Optionee is subject to
Section 16 of the Exchange Act, then the date of income recognition may be
deferred for up to six months.

          (iv)  Disposition of Shares.  In the case of an NSO, if Shares are
                ---------------------                        
held for at least one year, any gain realized on disposition of the Shares will
be treated as long-term capital gain for federal income tax purposes. In the
case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and are disposed of at least two years after the
date of grant, any gain realized on disposition of the Shares will also be
treated as long-term capital gain for federal income tax purposes. If Shares
purchased under an ISO are disposed of within such one-year period or within two
years after the date of grant, any gain realized on such disposition will be
treated as compensation income (taxable at ordinary income rates) to the extent
of the difference between the Exercise Price and the lesser of (1) the fair
market value of the Shares on the date of exercise, or (2) the sale price of the
Shares.

          (v)   Notice of Disqualifying Disposition of ISO Shares.  If the
                ------------------------------------------------- 
Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the date of grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

          (vi)  Section 83(b) Election for Unvested Shares Purchased Pursuant to
                ----------------------------------------------------------------
Nonqualified Stock Options.  With respect to the exercise of a nonqualified
- --------------------------                                                 
stock option for unvested Shares, an election may be filed by the Optionee with
the Internal Revenue Service within 30 days of the purchase of the Shares,
                             --------------                               
electing pursuant to Section 83(b) of the Code to be taxed currently on any
difference between the purchase price of the Shares and their Fair Market Value
on the date of purchase.  This will result in a recognition of taxable income to
the Optionee on the date of exercise, measured by the excess, if any, of the
fair market value of the Shares, at the time the Option is exercised over the
purchase price for the Shares.  Absent such an election, taxable income will be
measured and recognized by Optionee at the time or times on which the Company's
Repurchase Option lapses.  Optionee is strongly encouraged to seek the advice of
his or her own tax consultants in connection with the purchase of the Shares and

                                      -6-

the advisability of filing of the Election under Section 83(b) and similar tax
provisions.  A form of Election under Section 83(b) is attached hereto as
Exhibit C-5 for reference.

          (vii) Section 83(b) Election for Unvested Shares Purchased Pursuant
                -------------------------------------------------------------
to Incentive Stock Options.  With respect to the exercise of an incentive stock
- --------------------------                                                     
option for unvested Shares, an election may be filed by the Optionee with the
Internal Revenue Service within 30 days of the purchase of the Shares, electing
                         --------------                                        
pursuant to Section 83(b) of the Code to be taxed currently on any difference
between the purchase price of the Shares and their Fair Market Value on the date
of purchase for alternative minimum tax purposes.  This will result in a
recognition of income to the Optionee on the date of exercise, for alternative
minimum tax purposes, measured by the excess, if any, of the fair market value
of the Shares, at the time the option is exercised, over the purchase price for
the Shares.  Absent such an election, alternative minimum taxable income will be
measured and recognized by Optionee at the time or times on which the Company's
Repurchase Option lapses.  Optionee is strongly encouraged to seek the advice of
his or her tax consultants in connection with the purchase of the Shares and the
advisability of filing of the Election under Section 83(b) and similar tax
provisions.  A form of Election under Section 83(b) for alternative minimum tax
purposes is attached hereto as Exhibit C-5 for reference.

      OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE'S SOLE RESPONSIBILITY AND NOT
THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF OPTIONEE
REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON OPTIONEE'S
BEHALF.

                      INVESTMENT REPRESENTATION STATEMENT

 
OPTIONEE    :  Philip J. Koen
 
COMPANY     :  POINTCAST INCORPORATED
 
SECURITY    :  COMMON STOCK

AMOUNT      :  200,000 SHARES

DATE        :  October 30, 1997


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
not 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 and 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
statutes, 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 non-public offering subject to the satisfaction of
certain conditions.  Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Option to the Optionee, the exercise will be
exempt from registration under the Securities Act.  In the event the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144, including:  (1) the resale being made through
a broker in an unsolicited "broker's 
<PAGE>
 
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,
(3) the amount of Securities being sold during any three month period not
exceeding the limitations specified in Rule 144(e), and (4) the timely filing of
a Form 144, if applicable.

      In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than two years after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than three years, the satisfaction of the conditions set forth
in sections (1), (2), (3) and (4) of the paragraph immediately above.

          (d) Optionee further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding 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.

          (e) 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.

                            Signature of Optionee:

                            /s/ Philip J. Koen

nor actually present in this state if the sale of such securities is not in
violation of any securities law of the foreign state, territory or country
concerned;
      (8) to a broker-dealer licensed under the Code in a principal transaction,
or as an underwriter or member of an underwriting syndicate or selling group;

Commissioner's written consent is obtained or under this rule not required;
      (10) by way of a sale qualified under Sections 25111, 25112, 25113 or
25121 of the Code, of the securities to be transferred, provided that no order
under Section 25140 or subdivision (a) of Section 25143 is in effect with
respect to such qualification;
      (11) by a corporation to a wholly owned subsidiary of such corporation, or
by a wholly owned subsidiary of a corporation to such corporation;
      (12) by way of an exchange qualified under Section 25111, 25112 or 25113

Section 25143 is in effect with respect to such qualification;
      (13) between residents of foreign states, territories or countries who are
neither domiciled nor actually present in this state;
      (14) to the State Controller pursuant to the Unclaimed Property Law or to
the administrator of the unclaimed property law of another state; or
      (15) by the State Controller pursuant to the Unclaimed Property Law or by

such case, such person (i) discloses to potential purchasers at the sale that
transfer of the securities is restricted under this rule, (ii) delivers to each
purchaser a copy of this rule, and (iii) advises the Commissioner of the name of
each purchaser;
      (16) by a trustee to a successor trustee when such transfer does not
involve a change in the beneficial ownership of the securities;
      (17)  by way of an offer and sale of outstanding securities in an issuer
transaction that is subject to the qualification requirement of Section 25110 of
the Code but exempt from that qualification requirement by subdivision (f) of

thereof, shall bear on their face a legend, prominently stamped or printed

ANY INTEREST THEREIN, OR TO RECEIVE ANY CONSIDERATION THEREFOR, WITHOUT THE
PRIOR WRITTEN CONSENT OF THE COMMISSIONER OF CORPORATIONS OF THE STATE OF
CALIFORNIA, EXCEPT AS PERMITTED IN THE COMMISSIONER'S RULES."

                                1994 STOCK PLAN

                      RESTRICTED STOCK PURCHASE AGREEMENT


     THIS AGREEMENT is made between Philip J. Koen (the "Purchaser") and
PointCast Incorporated (the "Company") as of May 19, 1997.


                                    RECITALS
                                    --------

     (1) Pursuant to the exercise of the stock option granted to Purchaser under
the Company's 1994 Stock Plan and pursuant to the Stock Option Agreement (the
"Option Agreement") dated May 19, 1997 by and between the Company and Purchaser
with respect to such grant, which Option Agreement is hereby incorporated by
reference, Purchaser has elected to purchase Two Hundred Thousand (200,000)
shares which have not become vested under the vesting schedule set forth in the
Option Agreement ("Unvested Shares"). The Unvested Shares and the shares subject
to the Option Agreement which have become vested are sometimes collectively
referred to herein as the "Shares".

     (2) As required by the Option Agreement, as a condition to Purchaser's
election to exercise the option, Purchaser must execute this Restricted Stock
Purchase Agreement, which sets forth the rights and obligations of the parties
with respect to Shares acquired upon exercise of the Option.

     1.   Repurchase Option.
          ----------------- 

          (a) If Purchaser's Continuous Status as an Employee or Consultant is
terminated for any reason, including for cause, death, and disability, the
Company shall have the right and option to purchase from Purchaser, or
Purchaser's personal representative, as the case may be, all of the Purchaser's
Unvested Shares as of the date of such termination at the price paid by the
Purchaser for such Shares (the "Repurchase Option").

          (b) Upon the occurrence of such a termination, the Company may
exercise its Repurchase Option by delivering personally or by registered mail,
to Purchaser (or his transferee or legal representative, as the case may be),
within ninety (90) days of the termination, a notice in writing indicating the
Company's intention to exercise the Repurchase Option and setting forth a date
for closing not later than thirty (30) days from the mailing of such notice. The
closing shall take place at the Company's office.  At the closing, the holder of
the certificates for the Unvested Shares being transferred shall deliver the
stock certificate or certificates evidencing the Unvested Shares, and the
Company shall deliver the purchase price therefor.
<PAGE>
 
          (c) At its option, the Company may elect to make payment for the
Unvested Shares to a bank selected by the Company.  The Company shall avail
itself of this option by a notice in writing to Purchaser stating the name and
address of the bank, date of closing, and waiving the closing at the Company's
office.

          (d) If the Company does not elect to exercise the Repurchase Option
conferred above by giving the requisite notice within ninety (90) days following
the termination, the Repurchase Option shall terminate.

     2.   Transferability of the Shares; Escrow.
          ------------------------------------- 

          (a) Purchaser hereby authorizes and directs the secretary of the
Company, or such other person designated by the Company, to transfer the
Unvested Shares as to which the Repurchase Option has been exercised from
Purchaser to the Company.

          (b) To insure the availability for delivery of Purchaser's Unvested
Shares upon repurchase by the Company pursuant to the Repurchase Option under
Section 1, Purchaser hereby appoints the secretary, or any other person
designated by the Company as escrow agent, as its attorney-in-fact to sell,
assign and transfer unto the Company, such Unvested Shares, if any, repurchased
by the Company pursuant to the Repurchase Option and shall, upon execution of
this Agreement, deliver and deposit with the secretary of the Company, or such
other person designated by the Company, the share certificates representing the
Unvested Shares, together with the stock assignment duly endorsed in blank,
attached hereto as Exhibit C-2.  The Unvested Shares and stock assignment shall
be held by the secretary in escrow, pursuant to the Joint Escrow Instructions of
the Company and Purchaser attached as Exhibit C-3 hereto, until the Company
exercises its purchase right as provided in Section 1, until such Unvested
Shares are vested, or until such time as this Agreement no longer is in effect.
Upon vesting of the Unvested Shares, the escrow agent shall promptly deliver to
the Purchaser the certificate or certificates representing such Shares in the
escrow agent's possession belonging to the Purchaser, and the escrow agent shall
be discharged of all further obligations hereunder; provided, however, that the
escrow agent shall nevertheless retain such certificate or certificates as
escrow agent if so required pursuant to other restrictions imposed pursuant to
this Agreement.

          (c) The Company, or its designee, shall not be liable for any act it
may do or omit to do with respect to holding the Shares in escrow and while
acting in good faith and in the exercise of its judgment.

          (d) Transfer or sale of the Shares is subject to restrictions on
transfer imposed by any applicable state and federal securities laws.  Any
transferee shall hold such Shares subject to all the provisions hereof and the
Exercise Notice executed by the Purchaser with respect to any Unvested Shares
purchased by Purchaser and shall acknowledge the same by signing a copy of this
Agreement.

     3.   Ownership, Voting Rights, Duties.  This Agreement shall not affect in
          --------------------------------                                     
any way the ownership, voting rights or other rights or duties of Purchaser,
except as specifically provided herein.

     4.   Legends.  The share certificate evidencing the Shares issued hereunder
          -------                                                               
shall be endorsed with the following legend (in addition to any legend required
under applicable state securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT
BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE
SECRETARY OF THE COMPANY.

     5.   Adjustment for Stock Split.  All references to the number of Shares
          --------------------------                                         
and the purchase price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, stock dividend or other change in the
Shares which may be made by the Company after the date of this Agreement.

     6.   Notices.  Notices required hereunder shall be given in person or by
          -------                                                            
registered mail to the address of Purchaser shown on the records of the Company,
and to the Company at their respective principal executive offices.

     7.   Survival of Terms.  This Agreement shall apply to and bind Purchaser
          -----------------                                                   
and the Company and their respective permitted assignees and transferees, heirs,
legatees, executors, administrators and legal successors.

     8.   Section 83(b) Elections.
          ----------------------- 

          (a) Election for Unvested Shares Purchased Pursuant to Nonqualified
              ---------------------------------------------------------------
Stock Options.  Purchaser hereby acknowledges that he or she has been informed
- -------------                                                                 
that, with respect to the exercise of a nonqualified stock option for Unvested
Shares, that unless an election is filed by the Purchaser with the Internal
Revenue Service and, if necessary, the proper state taxing authorities, within
                                                                        ------
30 days of the purchase of the Shares, electing pursuant to Section 83(b) of the
- -------                                                                         
Code to be taxed currently on any difference between the purchase price of the
Shares and their fair market value on the date of purchase, there will be a
recognition of taxable income to the Optionee, measured by the excess, if any,
of the fair market value of the Shares, at the time the Company's Repurchase
Option lapses over the purchase price for the Shares.  Optionee represents that
Optionee has consulted any tax consultant(s) Optionee deems advisable in
connection with the purchase of the Shares or the filing of the Election under
Section 83(b).  A form of Election under Section 83(b) is attached hereto as
Exhibit C-4 for reference.

          (b) Election for Unvested Shares Purchased Pursuant to Incentive Stock
              ------------------------------------------------------------------
Options.  Purchaser hereby acknowledges that he or she has been informed that,
- -------                                                                       
with respect to the exercise of an incentive stock option for Unvested Shares,
that unless an election is filed by the Purchaser with 

                                      -4-

<PAGE>
 
the Internal Revenue Service within 30 days of the purchase of the Shares, 
                             --------------                          
electing pursuant to Section 83(b) of the Code to be taxed currently on any
difference between the purchase price of the Shares and their fair market value
on the date of purchase, there will be a recognition of income to the Optionee,
for alternative minimum tax purposes, measured by the excess, if any, of the
fair market value of the Shares, at the time the Company's Repurchase Option
lapses over the purchase price for the Shares. Optionee represents that Optionee
has consulted any tax consultant(s) Optionee deems advisable in connection with
the purchase of the Shares or the filing of the Election under Section 83(b) and
similar tax provisions. A form of Election under Section 83(b) for alternative
minimum tax purposes is attached hereto as Exhibit C-5 for reference.

     PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER'S SOLE RESPONSIBILITY AND NOT
THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF PURCHASER
REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER'S
BEHALF.

     9.   Representations.  Purchaser has reviewed with his own tax advisors the
          ---------------                                                       
federal, state, local and foreign tax consequences of this investment and the
transactions contemplated by this Agreement.  Purchaser is relying solely on
such advisors and not on any statements or representations of the Company or any
of its agents.  Purchaser understands that he (and not the Company) shall be
responsible for his own tax liability that may arise as a result of this
investment or the transactions contemplated by this Agreement.

     10.  Governing Law.  This Agreement shall be governed by and construed and
          -------------                                                        
enforced in accordance with California law.

     Purchaser represents that he has read this Agreement and is familiar with
its terms and provisions.  Purchaser hereby agrees to accept as binding,
conclusive and final all decisions or interpretations of the Board upon any
questions arising under this Agreement.

Dear Assistant Corporate Secretary:

     As Escrow Agent for both PointCast Incorporated (the "Company"), and the
undersigned purchaser of stock of the Company (the "Purchaser"), you are hereby
authorized and directed to hold the documents delivered to you pursuant to the
terms of that certain Restricted Stock Purchase Agreement ("Agreement") between
the Company and the undersigned, in accordance with the following instructions:

     1.   In the event the Company and/or any assignee of the Company (referred
to collectively for convenience herein as the "Company") exercises the Company's
repurchase option set forth in the Agreement, the Company shall give to
Purchaser and you a written notice specifying the number of shares of stock to
be purchased, the purchase price, and the time for a closing hereunder at the
principal office of the Company.  Purchaser and the Company hereby irrevocably
authorize and direct you to close the transaction contemplated by such notice in
accordance with the terms of said notice.

     2.   At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by
cash, a check, or some combination thereof) for the number of shares of stock
being purchased pursuant to the exercise of the Company's repurchase option.

     3.   Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such

Subject to the provisions of this paragraph 3, Purchaser shall exercise all
rights and privileges of a shareholder of the Company while the stock is held by
you.

     4.   Upon written request of the Purchaser, but no more than once per
calendar year, unless the Company's repurchase option has been exercised, you
will deliver to Purchaser a certificate or certificates representing so many
shares of stock as are not then subject to the Company's repurchase option.
Within 120 days after cessation of Purchaser's continuous employment by or
services to the Company, or any parent or subsidiary of the Company, you will
deliver to Purchaser a certificate or certificates representing the aggregate
number of shares held or issued pursuant to the Agreement and not purchased by
the Company or its assignees pursuant to exercise of the Company's repurchase
option.

     5.   If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to Purchaser,
you shall deliver all of the same to Purchaser and shall be discharged of all
further obligations hereunder.

     6.   Your duties hereunder may be altered, amended, modified or revoked

You shall not be personally liable for any act you may do or omit to do
hereunder as Escrow Agent or as attorney-in-fact for Purchaser while acting in
good faith, and any act done or omitted by you pursuant to the advice of your
own attorneys shall be conclusive evidence of such good faith.

     8.   You are hereby expressly authorized to disregard any and all warnings
given by any of the parties hereto or by any other person or corporation,
excepting only orders or process of courts of law and are hereby expressly
authorized to comply with and obey orders, judgments or decrees of any court.
In case you obey or comply with any such order, judgment or decree, you shall
not be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

obligations hereunder, may rely upon the advice of such counsel, and may pay
such counsel reasonable compensation therefor.

written notice to each party.  In the event of any such termination, the Company
shall appoint a successor Escrow Agent.

     13.  If you reasonably require other or further instruments in connection
with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

     14.  It is understood and agreed that should any dispute arise with respect
to the delivery and/or ownership or right of possession of the securities held
by you hereunder, you are authorized and directed to retain in your possession
without liability to anyone all or any part of said securities until such
disputes shall have been settled either by mutual written agreement of the
parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

     15.  Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon personal delivery or upon deposit in

to the initial full principal amount of the Note.

    VIII. Withdrawal or Substitution of Collateral.  Pledgor shall not sell,
          ----------------------------------------

property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

    XI.   Pledgeholder Liability.  In the absence of willful or gross

Agreement shall not render any other provision or provisions herein contained

          ---------------------
terms of this Security Agreement shall be binding on their respective successors

amended.

under the Plan is 200,000 Shares (the "POOL"), plus an annual increase to be
added on the first day of the Company's fiscal year (beginning in 1999) equal to
the lesser of (i) the number of Shares needed to restore the maximum aggregate
number of Shares available for sale under the Plan to 200,000 Shares, or (ii) a
lesser amount determined by the Board (the "Pool").  The Shares may be
authorized, but unissued, or reacquired Common Stock.

                                      -2-
<PAGE>
 
          If an Option expires or becomes unexercisable without having been
exercised in full, the unpurchased Shares which were subject thereto shall
become available for future grant or sale under the Plan (unless the Plan has
terminated).  Shares that have actually been issued under the Plan shall not be
returned to the Plan and shall not become available for future distribution
under the Plan.

     4.   Administration and Grants of Options under the Plan.  All grants of
          ---------------------------------------------------                
Options to Outside Directors under this Plan shall be automatic and
nondiscretionary and shall be made strictly in accordance with the following
provisions:

          (a)  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.

          (b)  Each Outside Director shall be automatically granted an Option to
purchase 20,000 Shares (the "First Option") on the date on which the later of
the following events occurs: (i) the date the Company's shareholders approve
the Plan, or (ii) the date on which such person first becomes an Outside
Director, whether through election by the stockholders of the Company or
appointment by the Board to fill a vacancy; provided, however, that an Inside
Director who ceases to be an Inside Director but who remains a Director shall
not receive a First Option.

          (c)  Each Outside Director shall be automatically granted an Option to
purchase 5,000 Shares (a "Subsequent Option") on the date of the annual meeting
of the stockholders of each year provided he or she is then an Outside Director
and if as of such date, he or she shall have served on the Board for at least
the preceding six (6) months.

          (d)  Notwithstanding the provisions of subsections (b) and (c) hereof,
any exercise of an Option granted before the Company has obtained stockholder
approval of the Plan in accordance with Section 16 hereof shall be conditioned
upon obtaining such stockholder approval of the Plan in accordance with Section
16 hereof.

          (e)  The terms of a First Option granted hereunder shall be as
follows:

               (i)   the term of the First Option shall be ten (10) years.

               (ii)  the First Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

               (iii) the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the First Option.

               (iv)  subject to Section 10 hereof, the First Option shall become
exercisable as to twenty-five percent (25%) of the Shares subject to the First
Option on the first anniversary of 

                                      -3-
<PAGE>
 
its date of grant, and 1/48 of the Shares subject to the First Option at the end
of each full month thereafter, provided that the Optionee continues to serve as
a Director on such dates.

          (f)  The terms of a Subsequent Option granted hereunder shall be as
follows:

               (i)   the term of the Subsequent Option shall be ten (10) years.

               (ii)  the Subsequent Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

               (iii) the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the Subsequent Option.

               (iv)  subject to Section 10 hereof, the Subsequent Option shall
become exercisable as to one hundred percent (100%) of the Shares subject to the
Subsequent Option on the fourth anniversary of its date of grant, provided that
the Optionee continues to serve as a Director on such date.

          (g)  In the event that any Option granted under the Plan would cause
the number of Shares subject to outstanding Options plus the number of Shares
previously purchased under Options to exceed the Pool, then the remaining Shares
available for Option grant shall be granted under Options to the Outside
Directors on a pro rata basis.  No further grants shall be made until such time,
if any, as additional Shares become available for grant under the Plan through
action of the Board or the stockholders to increase the number of Shares which
may be issued under the Plan or through cancellation or expiration of Options
previously granted hereunder.

     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 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 the Director's relationship with the Company at any time.

     6.   Term of Plan.  The Plan shall become effective upon the approval by
          ------------                                                       
the stockholders of the Company.  It shall continue in effect for a term of ten
(10) years unless sooner terminated under Section 11 hereof.

     7.   Form of Consideration.  The consideration to be paid for the Shares to
          ---------------------                                                 
be issued upon exercise of an Option, including the method of payment, shall
consist of (i) cash, (ii) check, (iii) other shares which (x) 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 (y) have a Fair Market
Value on the date of surrender equal to the aggregate exercise price of the
Shares as to which 

                                      -4-
<PAGE>
 
said Option shall be exercised, (iv) consideration received by the Company under
a cashless exercise program implemented by the Company in connection with the
Plan, or (v) any combination of the foregoing methods of payment.

     8.   Exercise of Option.
          ------------------ 

          (a)  Procedure for Exercise; Rights as a Stockholder. Any Option
               -----------------------------------------------            
granted hereunder shall be exercisable at such times as are set forth in Section
4 hereof; provided, however, that no Options shall be exercisable until
stockholder approval of the Plan in accordance with Section 16 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 7 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.
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
shall 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 10 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 Continuous Status as a Director.  Subject to
               ----------------------------------------------             
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or Disability), the Optionee may exercise
his or her Option, but only within three (3) months following the date of such
termination, and only to the extent that the Optionee was entitled to exercise
it on the date of such termination (but in no event later than the expiration of
its ten (10) year term).  To the extent that the Optionee was not entitled to
exercise an Option on the date of such termination, and to the extent that the
Optionee does not exercise such Option (to the extent otherwise so entitled)
within the time specified herein, the Option shall terminate.

          (c)  Disability of Optionee.  In the event Optionee's status as a
               ----------------------                                      
Director terminates as a result of Disability, the Optionee may exercise his or
her Option, but only within twelve (12) months following the date of such
termination, and only to the extent that the Optionee was entitled to exercise
it on the date of such termination (but in no event later than the expiration of
its ten (10) 

                                      -5-
<PAGE>
 
year term). To the extent that the Optionee was not entitled to exercise an
Option on the date of termination, or if he or she does not exercise such Option
(to the extent otherwise so entitled) within the time specified herein, the
Option shall terminate.

          (d)  Death of Optionee.  In the event of an Optionee's death, the
               -----------------                                           
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term).  To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

     9.   Non-Transferability of Options.  Unless provided otherwise by the
          ------------------------------                                   
Administrator, 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.  If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

     10.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
          ------------------------------------------------------------------
Asset Sale.
- ---------- 

          (a)  Changes in Capitalization.  Subject to any required action by the
               -------------------------                                        
stockholders of the Company, the number of Shares covered by each outstanding
Option, the number of Shares 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 covered by each such outstanding Option, and the number of
Shares issuable pursuant to the automatic grant provisions of Section 4 hereof
shall be proportionately adjusted for any increase or decrease in the number of
issued Shares 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 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."  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
subject to an Option.

          (b)  Dissolution or Liquidation.  In the event of the proposed
               --------------------------                               
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it shall terminate immediately prior to the
consummation of such proposed action.

          (c)  Merger or Asset Sale.  In the event of a merger of the Company
               --------------------                                          
with or into another corporation or the sale of substantially all of the assets
of the Company, (i) outstanding Options shall have their vesting accelerated as
to an additional twenty-five percent (25%) of the 

                                      -6-
<PAGE>
 
Shares subject to such Option effective immediately prior to the consummation of
such merger or asset sale, and (ii) outstanding Options may be assumed or
equivalent options may be substituted by the successor corporation or a Parent
or Subsidiary thereof (the "Successor Corporation"). If an Option is assumed or
substituted for, the Option or equivalent option shall continue to be
exercisable as provided in Section 4 hereof for so long as the Optionee serves
as a Director or a director of the Successor Corporation. If the Successor
Corporation does not assume an outstanding Option or substitute for it an
equivalent option, the Option shall terminate as of the date of the closing of
the merger or asset sale.

     For the purposes of this Section 10(c), an Option shall be considered
assumed if, following the merger or sale of assets, the Option confers the right
to purchase or receive, for each Share of Optioned Stock subject to the Option
immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the effective date of
the transaction (and if holders were offered a choice of consideration, the type
of consideration chosen by the holders of a majority of the outstanding Shares).
If such consideration received in the merger or sale of assets is not solely
common stock of the successor corporation or its Parent, the Administrator may,
with the consent of the successor corporation, provide for the consideration to
be received upon the exercise of the Option, for each Share of Optioned Stock
subject to 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 in the merger or sale of assets.

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

          (a)  Amendment and Termination.  The Board may at any time amend,
               -------------------------                                   
alter, suspend, or discontinue the Plan, but no amendment, alteration,
suspension, or discontinuation shall be made which would impair the rights of
any Optionee under any grant theretofore made, without his or her consent.  In
addition, to the extent necessary and desirable to comply with any applicable
law,  regulation or stock exchange rule, the Company shall obtain stockholder
approval of any Plan amendment in such a manner and to such a degree as
required.

          (b)  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.

     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 hereof.

     13.  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 

                                      -7-
<PAGE>
 
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.

          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.

     14.  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.

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

     16.  Stockholder Approval. The Plan shall be subject to approval by the
          --------------------                                              
stockholders of the Company within twelve (12) months after the date the Plan is
adopted.  Such stockholder approval shall be obtained in the degree and manner
required under applicable state and federal law and any stock exchange rules.

the following,
<PAGE>
 
or a combination thereof, at the election of the Optionee:

          (a)  cash;

          (b)  check; or

          (c)  surrender of other shares which (x) in the case of Shares

such other documentation as the Company 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.

     5.   Restrictions on Exercise.  This Option may not be exercised if the
          ------------------------                                          
issuance of such Shares 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 regulations, or if such issuance
would not comply with the requirements of any stock exchange upon which the
Shares may then be listed. 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.   Non-Transferability of Option.  This Option may not be transferred in
          -----------------------------

successors and assigns of the Optionee.

     7.   Term of Option.  This Option may not be exercised more than ten (10)

exercise of this
<PAGE>
 
Option, he or she will recognize income for tax purposes in an amount equal to
the excess of the then Fair Market Value of the Shares purchased over the
exercise price paid for such Shares.  Since the Optionee is subject to Section
16(b) of the Securities Exchange Act of 1934, as amended, under certain limited
circumstances the measurement and timing of such income (and the commencement of
any capital gain holding period) may be deferred, and the Optionee is advised to
contact a tax advisor concerning the application of Section 83 in general and
the availability a Section 83(b) election in particular in connection with the
exercise of the Option.  Upon a resale of such Shares by the Optionee, any
difference between the sale price and the Fair Market Value of the Shares on the
date of exercise of the Option, to the extent not included in income as
described above, will be treated as capital gain or loss.

     Optionee acknowledges receipt of a copy of the Plan, a copy of which is
attached hereto, and represents that he or she is familiar with the terms and
provisions thereof, and hereby accepts this Option subject to all of the terms
and provisions thereof.  Optionee hereby agrees to accept as binding, conclusive
and final all decisions or interpretations of the Board upon any questions
arising under the Plan.

                              ----------                                        
adopted Counterpart) and shall adjust appropriately upon admission of any new
Members and other events.

     2.2  Capital Contributions.
          --------------------- 

          (a)  Upon execution of this Agreement, PCI has contributed to the
capital of LLC (i) cash in the amount of $1 million, and (ii) certain rights to
PCI technology as specified in the Technology and Trademark License Agreement,
which rights have a fair market value as of the date hereof, as agreed by the
Members, of $2 million.  PCI's initial Capital Account balance shall equal $3
million, subject to adjustment hereafter as provided in Section 2.5 of this
Agreement. The contributions made by PCI and TCI under this Section 2.2, and any
subsequent contributions of capital by Members to LLC under Sections 2.3 or 2.4,
are hereafter referred to as "Capital Contributions."

          (b)  Upon execution of this Agreement, TCI has contributed to the
capital of LLC (i) cash in the amount of $2 million, and (ii) the commercial
exploitation rights in respect of the localized PointCast network in Japan

initial Capital Account balance shall equal $2 million, subject to adjustment
hereafter as provided in Section 2.5 of this Agreement.

          (c)  In the event that the Board from time to time hereafter
determines that LLC requires additional funding in excess of the amounts
contributed to LLC pursuant to this Section 2.2 (and Section 2.4, if applicable)
and any amounts advanced pursuant to Section 2.3, then the Members may (but
shall have no obligation to) make, and LLC shall accept, such additional Capital
Contributions on such terms as may be agreeable to the contributing Member and
LLC.

     2.3  Member Advances.  In addition to the Capital Contributions provided
          ---------------                                                    
for under Section 2.2, the Members may, if the Board in its discretion deems it
appropriate, make cash advances in such amounts and upon such repayment,
interest and other terms as the Board and the Member providing such advance
shall agree.  Any such cash advances shall be treated as loans to LLC rather
than Capital Contributions and shall therefore not affect a Member's Capital
Account.

     2.4  Additional Members.  Subject to Section 3.3 hereof, the Board may
          ------------------                                               
admit additional Members and accept additional Capital Contributions from such
additional Members from time to time and on such terms as the Board deems
appropriate in its sole discretion, and (other than such approval of the Board
and, if applicable under Section 3.3, TCI) no approval from the Members shall be
required for such actions.  Notwithstanding the preceding sentence, no
additional Member shall be admitted (a) which is a direct competitor of PCI or
TCI unless such Member consents to such admission, or (b) upon terms which would
disproportionately 

                                      -5-
<PAGE>
 
reduce either PCI's or TCI's Percentage Interest relative to the interests of
other Member(s). Any additional Members who may hereafter be admitted to LLC
shall make such Capital Contributions for such interests in LLC as the Board and
such additional Member shall mutually agree. No Member shall be obligated or
permitted to make any other Capital Contributions except as otherwise provided
in this Article II.

     2.5  Capital Accounts.
          ---------------- 

          (a)  A separate capital account (a "Capital Account") shall be
maintained for each Member strictly in accordance with the rules set forth in
Treasury Regulations Section 1.704-1(b)(2)(iv).  Subject to the preceding
sentence, each Member's Capital Account shall be (i) increased by the amount of
Capital Contributions made by such Member to LLC and allocations to such Member
of Company Profits and other items of book income and gain; and (ii) decreased
by the amount of money and fair market value of property (net of liabilities
secured by such distributed property that such Member is considered to assume or
take subject to under Section 752 of the Code) distributed to it by LLC and
allocations to such Member of LLC Loss and other items of book loss and
deductions; and (iii) otherwise adjusted in accordance with the additional rules
set forth in Treasury Regulations Section 1.704-1(b)(2)(iv).

          (b)  In the event the Book Values of LLC assets are adjusted pursuant
to Treasury Regulations Section 1.704-1(b) and Section 1.9(u), the Capital
Accounts of all Members shall be adjusted simultaneously to reflect the
allocations of income, gain, loss or deduction that would be made to the Members
if there were a taxable disposition of LLC's property for its fair market value.
If any assets of LLC are to be distributed in kind, such assets shall be
distributed on the basis of their fair market values after the Members' Capital
Accounts have been adjusted to reflect the manner in which any unrealized income
gain, loss or deduction with respect to such assets (that have not been
reflected in the Capital Accounts previously) would be allocated between the
Members if there were a taxable disposition of the property for its fair market
value.

          (c)  If any interest in LLC is transferred in accordance with the
provisions of this Agreement, the transferee Member shall succeed to that
portion of the Capital Account of the transferring Member as relates to such
transferred interest.

          (d)  It is the intent of LLC that the Capital Accounts of all Members
be determined and maintained in accordance with the principles of Treasury
Regulations Section 1.704-1 at all times throughout the full term of LLC and the
foregoing provisions of this Section 2.5 shall be interpreted in accordance with
such intention.

     2.6  Return of Capital; Partition.  Except as otherwise provided herein, no
          ----------------------------                                          
Member shall have any right to (a) withdraw from LLC, (b) demand the return of
all or any part of such Member's capital during the term of LLC or (c) receive a
return of such Member's capital from any specific assets of LLC.  Each Member
irrevocably waives any right which such Member may have to cause a partition of
all or any part of LLC's assets.  No Member shall be entitled to receive any
interest with respect to a Capital Contribution.

contained, no Member shall be liable for any debts, expenses, liabilities or
obligations of LLC in excess of such Member's Capital Contribution except as may
be provided in the Act.  To the extent required by law, any capital distributed
to a Member shall be restored to LLC as necessary to meet such Member's share of
any liability or loss of LLC.

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

to cause the Members' Capital Accounts to be in such proportion.

                                      -11-
<PAGE>
 
     6.2  Special Allocations for U.S. Tax Purposes.
          ----------------------------------------- 

          (a) If LLC ever has "partnership minimum gain" or "partner minimum
gain" (as defined by Treasury Regulations Section 1.704-2), then the rules of
such Regulations regarding allocation and chargebacks of such items shall apply.

          (b) All deductions, losses, and Code Section 705(a)(2)(B) expenditures
of LLC, as the case may be, that are treated under Treasury Regulations Section
1.704-2(b) as attributable to "partner nonrecourse debt" of LLC shall be
allocated to the Members bearing the risk of loss with respect to such
liabilities in accordance with such Treasury Regulations.

          (c) If any Member unexpectedly receives an adjustment, allocation, or
distribution described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4),
(5) or (6) which creates or increases a deficit in such Member's Capital Account
in excess of such Member's share of partnership minimum gain and partner minimum
gain (as determined under Treasury Regulations Section 1.704-2), if any, such
Member shall be allocated items of book income and gain in an amount and manner
sufficient to eliminate or to reduce, as quickly as possible, such deficit.  For
purposes of this Section 6.2(c), Capital Accounts shall be adjusted
hypothetically as provided for in Treasury Regulations Section 1.704-
(b)(2)(ii)(d).  The Members intend that the provision set forth in this Section
6.2(c) shall constitute a "qualified income offset" as described in such section
of the Treasury Regulations and this Section 6.2(c) shall be interpreted
consistent with such intention.

     6.3  Time of Allocations.  The Profit, Loss and other items of LLC for each
          -------------------                                                   
fiscal year shall be allocated to the Members' Capital Accounts at the end of
such fiscal year in accordance with the provisions of Sections 6.1 and 6.2.

     6.4  Distributions.  Subject to Section 3.3, LLC shall distribute its
          -------------                                                   
Distributable Cash for any fiscal year as follows:

          (a)  First, to the Members in amounts equal to (i) the higher of the
combined effective federal and California maximum corporate income tax rates
(taking into account the deductibility of state taxes against federal income,
currently 41%) or the effective Japanese tax corporate income tax rate in effect
for such fiscal year, multiplied by (ii) the amount by which LLC's Profit
allocated to such Member for such fiscal year, if any, exceeds the cumulative
net Loss, if any, allocated to such Member since the inception of LLC, with any
such distribution made no later than 90 days after the end of each fiscal year
of LLC.

          (b)  Thereafter, if the Board deems it appropriate in its sole
discretion, any remaining Distributable Cash shall be distributed to the Members
in proportion to their respective Percentage Interests, as determined by the
Board, in its discretion, within ninety (90) days following the end of such
fiscal year.  Any distributions made to the Members under subsection (a) shall
be credited against and reduce by a corresponding amount the distributions to
which such Members are entitled under this subsection (b).

                                      -12-
<PAGE>
 
          (c)  LLC shall withhold all such amounts as may be required by
applicable law and any amounts so withheld shall be deemed to have been
distributed under this Section 6.4 to the Member with respect to whom such
withholding obligation arose and, to the extent such amounts exceed the amount
such Member would have otherwise received, shall be counted towards and reduce
by a corresponding amount future distributions to such Member.

          (d)  Notwithstanding any other provision herein, no distribution shall
be made to the Members which would render LLC insolvent.

     6.5  Tax Return.  LLC shall, within 90 days after the end of each calendar
          ----------                                                           
year, file a federal income tax information return and transmit to each Member a
copy of such return and a schedule (Schedule K-1 or successor schedule) showing
such Member's distributive share of LLC's income, deductions and credits.

     6.6  Allocation of Certain Tax Items for U.S. Income Tax Purposes.  If any
          ------------------------------------------------------------         
property of LLC is reflected in the Capital Accounts of the Members and on the
books of LLC at a Book Value that differs from the adjusted tax basis of such
property, then the tax items with respect to that property shall, in accordance
with Treasury Regulations Section 1.704-1(b)(4)(i), be shared among the Members
in a manner that takes account of the variation between the adjusted tax basis
of the applicable property and its Book Value in the same manner as variations
between the adjusted tax basis and fair market value of property contributed to
LLC are taken into account in determining the Members' share of tax items under
Code Section 704(c).

     6.7  Allocation Between Transferor and Transferee.  The proportion of the
          --------------------------------------------                        
income, gain, loss, deductions and credits of LLC for any fiscal year of LLC
during which any Percentage Interest in LLC is transferred by a Member to
another party pursuant to the terms hereof that is allocable in respect of such
Percentage Interest shall be apportioned between the transferor and the
transferee of the Percentage Interest on the basis of the number of days during
such fiscal year that each is the owner thereof, without regard to (a) the
results of LLC's operations before or after the effective date of the transfer,
or (b) any distributions made to the Members before or after the date of the
transfer.

     6.8  Tax Allocations Binding.  The Members are aware of the income tax
          -----------------------                                          
consequences of the allocations made by this Article VI and hereby agree to be
bound by the provisions of this Article VI in reporting their shares of LLC
allocations for income tax purposes.

transferred by any Member, directly or indirectly, without the approval of
Members holding a majority of the Percentage Interests of LLC then outstanding.

     7.2  Rights of First Refusal.  Without limiting the provisions of Section
          -----------------------

<PAGE>
 
proposing such transfer (the "transferring Member") shall provide the other
Members (the "non-transferring Members") with notice of such proposed transfer,
which notice shall include a description of all terms of such transfer
(including the amount to be transferred, the price to be paid and the date of
the proposed transfer), and the name, address and telephone number of the
proposed transferee. Each non-transferring Member shall have the right,
exercisable by notice to the transferring Member within 30 days following
receipt of such notice, to purchase all or any part of the Percentage Interest
to be transferred upon the terms and conditions set forth in the transferring
Member's notice, up to that portion of such Percentage Interest as equals the
ratio of such non-transferring Member's Percentage Interest to the aggregate
Percentage Interests of all of the non-transferring Members. In the event that
any non-transferring Member elects not to exercise all or any part of its
purchase right as set forth in the preceding sentence, the transferring Member

the transferee in any respect) with respect to the unpurchased remainder of such

in Section 3.3 and TCI refuses to grant its Approval to such action, then PCI
and TCI shall negotiate in good faith the purchase by either of them of the
Percentage Interest of the other or shall, subject to the provisions of this
Agreement, attempt to negotiate a sale of either of their Percentage Interests
to a third party.  If such negotiations fail to result in a mutually acceptable
resolution within a reasonable period of time (as mutually agreed by PCI and
TCI), then LLC shall be dissolved in accordance with the provisions of Article X
of this Agreement.

provided herein), or the expiration of the term of LLC as provided in Section

or the property shall be distributed in kind to the Members after payment of the

distribution.

for such Member's own account, for investment, and not with a view to or for
sale in connection with any distribution thereof, nor with any present intention

such Member understands that such Member must bear the economic risk of such
Member's investment in such LLC for an indefinite period of time because such
Percentage Interest has not been registered under the 1933 Act or
registered/qualified under applicable laws and therefore cannot be sold unless

registration and qualification are available, and LLC is under no obligation to
so register or qualify any Percentage Interest or to comply with any exemption
and has no current intention of so doing.

     11.3  Restricted Securities; Absence of Trading Market.  Each Member

further hereby represents that such member understands that (a) such member's
Percentage Interest constitute "restricted securities" under the 1933 Act and
that Rule 144 promulgated under the 1933 Act is not now available with respect
to the transfer of such Member's Percentage Interest and that there is no
present likelihood that it will be available in the future, (b) that there is no
public market for such Percentage Interest and there is no present likelihood
that any such market will develop, and (c) LLC is newly formed and has no
earnings or operating history.

     11.4  Preexisting Relationship; Investment Experience.  Each Member
           -----------------------------------------------              
represents and warrants (a) that such Member has a preexisting personal or
business relationship with the other, such that such Member is aware of the
character, business acumen and general business and financial circumstances of
such party, or (b) that either alone or with a purchaser representative, such
Member can bear the economic risk of the investment in LLC and has such
knowledge and experience in financial or business matters that such Member is
capable of evaluating the merits and risks of an investment in LLC.

     11.5  Accredited Investor.  Each Member represents that such Member is an
           -------------------                                                
"accredited investor" for purposes of Rule 501(a) promulgated under the 1933
Act.

     11.6  Economic Risk.  Each Member hereby represents that such Member has
           -------------                                                     
adequate net worth and means for providing for such Member's current needs and
personal contingencies to sustain a complete loss of such Member's investment,
is able to bear such a loss, and that such Member has no need of liquidity of
such Member's investment.

     11.7  Resale.  Each Member hereby represents such Member's awareness that
           -------                                                            
such Member's rights to transfer such Member's Percentage Interest will be
restricted by the 1933 Act, the applicable laws, and this Agreement; that any
certificates or other documents evidencing such Member's Percentage Interest may
bear the legends relating to those restrictions which are set forth below; and
that corresponding notations will be made by LLC in its appropriate records.

             EXHIBIT A TO COMMERCIAL EXPLOITATION RIGHTS AGREEMENT

The following is a listing of marks and logos licensed under Section 2(b) of the
Commercial Exploitation Rights Agreement:

PointCast(TM)
PointCast Network(TM)

The PointCast logo icon is comprised of a purple square containing a white 
broadcast tower with a yellow dot in the center. The icon is a square and should
account for one quarter the length of the logo (not including the TM symbol). 
For example, if the PointCast logo word is represented as 4 inches long, the 
tower icon should be a one inch square.

The PointCast Corporate Signature can appear in either a centered (primary) or 
horizontal configuration. The centered configuration is the primary orientation 
and should be used whenever possible. The horizontal configuration can be used 
when there are size or space limitations. In the centered configuration, the 
logotype PointCast (black) should lie centered beneath the tower icon 
(purple/yellow). In the horizontal configuration, the logotype should lie to the
right of the purple tower icon. The logo word PointCast may reside without the 
icon however, the tower icon may not reside without the logo word PointCast. The
logo word "PointCast" must always be black unless approved by PointCast 
Marketing. The tower icon must always appear in the Pantone colors indicated in 
the corporate palette unless approved by PointCast Marketing. The clear-space 
area should measure at least 1/2x on all sides of the PointCast Corporate 
Signature, where x equals the height of the logo icon. Placement of the 
trademark symbol (TM) should also appear after the word PointCast.

            [EXAMPLE OF POINTCAST LOGO, WITH TOWER ICON ABOVE NAME]

         [EXAMPLE OF POINTCAST LOGO, WITH TOWER ICON TO LEFT OF NAME]

The corporate palette is comprised of two colors: Purple is the primary color, 
Yellow is the secondary color and Black. The PMS, RGB and CMYK formulas are 
listed below. When necessary PointCast Signature can also appear in Black and 
White, please make sure the logo icon and the logotype is in black. The dot 
above the tower should be white.

fix any reproducible programming error identified by NewCo in the Localized
Versions of the Client-Side Software or the Server-Side Software.

     d.  Updates and Upgrades.  PCI shall use commercially reasonable efforts to
         --------------------                                                   
provide updates and upgrades to the Localized Versions of the Client-Side
Software and the Server-Side Software, as PCI in its sole discretion shall
determine, for the purpose of (i) adding channels to such Localized Versions as
requested by NewCo and agreed to by PCI, and (ii) adding functionality developed
by PCI for implementation in the PointCast Network that PCI deems appropriate
for the Localized PointCast Network.

     e.  Limitations.  NewCo acknowledges that PCI shall not be obligated under

training obligations under this Agreement, NewCo shall pay PCI a yearly fee (the
"Support Fee"), payable in advance.  The Support Fee for the first year of this
Agreement shall be US$[*], and shall be paid on the Effective Date.

Fee for the second year of this Agreement will be US$[*]. NewCo shall pay the
Support Fee for such years following the first year on the appropriate

conditions set forth in this Agreement.

     NOW, THEREFORE, EDS and PointCast hereby agree to the following:

     Order.

     (b) "PCN" means the PointCast NetworkTM, a network of servers that delivers
     news and information content over the Internet to Viewers via PCN Clients
     on the Viewers' desktop computers.

     (c) "PCN Client" means the portion of the PointCast software for PCN which

     and animated advertisement player capable of delivering information via
     PCN.

     (d) "Technology" means deliverables specifically required by a Work Order

     without limitation, the assignment of copyrights in all such deliverables
     to PointCast.

     (e) "Viewer" means a user who accesses PCN using a PCN Client.

     (f) "Work Order" means a supplement to this Agreement in the form of an

     services, all as more particularly described in Section 2 below.

2.   WORK ORDERS.
     -----------

     From time to time during the Term of this Agreement, EDS and PointCast may
     execute a Work Order for agreed upon services to be provided by EDS, the
     applicable acceptance criteria and performance standards for such work, the
     support obligations of PointCast, and the payment obligations of PointCast
     under this Agreement. Each such Work Order shall consist of a Schedule A
     describing the services to be delivered by and other obligations of EDS,
     a Schedule B describing the obligations of PointCast, and a Schedule C
     describing the payment obligations of PointCast. Each such Work Order
     shall be signed by authorized representatives of both parties and shall
     be attached to this Agreement and, when so executed and attached, shall
     be subject to the terms and conditions of this Agreement. Work Orders
     shall be numbered



                                                                               1

<PAGE>
 
consecutively beginning with number 1, attached hereto. If there is a conflict 
between the terms of this Agreement and the terms of any Work Order, the terms
of the Work Order shall take precedence.

3.   EDS SERVICES.
     ------------

     (a)  EDS will provide the EDS Services to PointCast pursuant to the terms
          and conditions of this Agreement, including the applicable Work
          Order. Each Work Order when attached to this Agreement shall be
          incorporated herein by reference.

     (b)  The EDS Services will be undertaken at various PointCast or EDS
          sites to be identified and mutually agreed upon by the parties and
          identified in the applicable Work Order (the "Facilities").

     ----
     will end on the third anniversary of the Effective Date, unless sooner
     terminated as provided in this Agreement, and shall automatically renew
     for successive one year periods for so long as there are outstanding
     obligations of the parties under any Work Order attached hereto. The term
     of this Agreement may be extended by the mutual written agreement of the
     parties. If the term is extended because of outstanding obligations of
     the parties under and Work Order, the Agreement will terminate as soon as
     such obligations have been performed.

5.   ACCOUNT MANAGERS.  Within 24 hours of signing this Agreement, EDS and 
     ----------------
     PointCast shall each designate and maintain, respectively, a
     representative who will be the primary point of contact of such party in
     dealing with the other with respect to the EDS Services (each, the
     respective party's "Account Manager"). If called for in an applicable
     Work Order, each party shall provide the other party's Account Manager at
     no charge to such other party with furnished office space, administrative
     support, and voice and data networking services in the host party's
     facility. The Account Manager of each party will have the authority and
     power to make decisions with respect to actions to be taken by such party
     in connection with the EDS Services within the scope of this Agreement
     and the attached Work Orders. EDS and PointCast shall mutually consult
     regarding the nomination of and shall have the right to request
     replacement of the other party's Account Manager and other key team
     members described in the applicable Work Order, and the party to which
     the request has been made will consult with the requesting party on the
     selection of a replacement and will use reasonable efforts to accommodate
     the request as promptly as is practicable.

6.   COMPENSATION; BOOKS AND RECORDS.  EDS shall not be entitled to 
     -------------------------------
     compensation for any services which are not authorized in an applicable
     Work Order unless such services have been authorized in advance in
     writing by the PointCast Account Manager in the form of an executed
     modification to such Work order. If EDS is to be reimbursed for costs and
     expenses incurred in connection with the EDS Services or for any EDS
     Services performed on other than a fixed-price basis, EDS shall maintain
     comprehensive books and records to substantiate both the services and
     expenses. Such books and records will be retained by EDS for a period of
     at least two (2) years from and after the completion of the services to
     which they apply. PointCast or its designated agent shall have the right
     to audit such records at all reasonable times upon five (5) business
     days' prior written notice to EDS. In no event will PointCast have the
     right to review any records related to other customers of EDS.

7.   PAYMENTS; REIMBURSEMENT.  PointCast will pay EDS the aggregate of the 
     -----------------------
     amounts described in Schedule C of the applicable Work Order in
     accordance with the payment provisions set forth in such Schedule C. If
     any Work Order calls for reimbursements of EDS by PointCast for travel
     and other expenses, the following terms and conditions shall apply: EDS
     agrees to use its best efforts to keep travel and living expenses as
     economical as possible and within a moderate range. Absent PointCast's
     prior written approval, PointCast will not be liable to reimburse EDS for
     airfare in excess of coach class. Reimbursable expenses shall include
     travel and related lodging and meals, long-distance telephone charges,
     postage and other shipping charges. Expenses for facsimile, duplication,
     supplies, word-processing and local telephone charges will be borne by
     EDS and will not be chargeable to PointCast. EDS shall secure PointCast's
     written approval prior to incurring any individual reimbursable
     expenditure exceeding five hundred dollars ($500) in connection with the
     EDS Services. EDS will bill PointCast monthly at EDS' cost for all such
     routine reimbursable charges, and payment will be due within thirty (30)
     days of receipt of EDS' properly submitted invoice. All invoices
     submitted to PointCast by EDS for any expenses for which EDS claims
     reimbursement shall include a detailed listing of all out-of-pocket
     disbursements together with supporting documentation, including, without
     limitation, copies of hotel bills and airline tickets.


                                                                               2

     set forth in this Agreement, PointCast, at its cost and expense, will have
     the responsibilities assigned to it in Schedule B to each of the Work
     Orders attached hereto from time to time.


9.   EMPLOYEE BENEFITS.  The EDS personnel performing the EDS Services will be
     -----------------
     and remain the employees of EDS, and EDS will provide for and pay the
     compensation and other benefits of such employees including salary, health,
     accident and workers' compensation benefits and all taxes and contributions
     which an employer is required to pay relating to the employment of
     employees.

     -------------------
     Agreement and for a period of 12 months thereafter, neither party will,

     a subcontractor to the other party or an employee thereof) and who has been
     introduced to the other party in connection with this Agreement.


11.  PROPRIETARY RIGHTS.
     ------------------

(a)  POINTCAST INFORMATION.  As between PointCast and EDS, information relating
     to PointCast, PCN, PointCast's affiliates, Viewers and customers of PCN and
     the PCN Client and other PointCast software will remain the sole and
     exclusive property of PointCast.  EDS is hereby authorized during the term
     of this Agreement to have access to and to make use of such information
     only to the extent necessary for the performance of its obligations
     hereunder.  EDS' access and use of such information shall be governed by
     the terms of Section 12.

(b)  TECHNOLOGY.  Unless otherwise agreed by the parties in writing in the
     applicable Work Order, PointCast shall own the copyright in and to the
     Technology (and all renewals and extensions thereof).  EDS hereby makes a
     full, irrevocable assignment, in perpetuity, to PointCast, of the
     Technology and such copyrights.

(c)  FURTHER ASSURANCES.  EDS shall, and shall cause any parties acting under it
     in relation to this Agreement, to execute any and all documents and do such
     other acts requested at any time by PointCast as may be required to
     evidence, confirm and/or further effect the rights granted PointCast under
     this Agreement, including without limitation the rights under this Section
     11. EDS shall establish and maintain written agreements with its employees
     and such parties sufficient to enable EDS to comply with the provisions of
     the foregoing sentence.

(d)  ACCESS; RETURN OF MATERIALS.  PointCast shall have continuous access to the
     Facilities and to all data, documents, computer software, Content (as
     defined in Section 14), Technology and other materials provided to EDS by
     PointCast.  EDS will return the original and any copies of all Technology
     and all data, documentation, software, Content and other materials promptly
     upon PointCast's request.  Upon the expiration or earlier termination of
     this Agreement for any reason whatsoever, EDS shall promptly return the
     original and any copies of all Technology and all data, documents, computer
     software, Content and other materials provided by PointCast, in whatever
     stage of completion, to PointCast, or PointCast's designated agent.

12.  CONFIDENTIALITY  Except as otherwise expressly provided in this Agreement,
     ---------------
     EDS and PointCast each agree that all information communicated to it by or
     on behalf of the other, whether before or after the Effective Date, which
     is marked or identified or otherwise deemed confidential as described
     below, will be and will be deemed to have been received in strict
     confidence and will be used only as required to carry out the recipient
     party's obligations or exercise the recipient party's rights under this
     Agreement. EDS and PointCast each agree that it will use the same means as
     it uses to protect its own confidential information, but in any event not
     less than reasonable means including written agreements, to prevent the
     disclosure and to protect the confidentiality of the other party's
     confidential information. No such information, including the terms of this
     Agreement, will be disclosed by the recipient party, its agents,
     representatives or employees without the prior written consent of the other
     party; provided, however, that each party may


                                                                               3

<PAGE>
 
disclose such information to those of its third party consultants identified to,
and approved by, the other party and employees, in each case having a need for
access to such information for purposes of this Agreement and with respect to
each of whom such party has taken steps, no less rigorous than what it would do
to protect its own proprietary information, but in any event at least reasonable
steps including written agreements, to prevent any such employees or consultants
from acting in any manner inconsistent with this Section 12.  Recipient's
obligations of non-disclosure under this Section 12 shall not apply to
Information which; (a) is already known to the recipient party and is not
governed by the term of another separate nondisclosure agreement with the
disclosing party, (b) is publicly known or becomes publicly known through no
unauthorized act of the recipient party, (c) is rightfully received from a third
party, authorized to disclose such information (d) is independently developed
without use of the other party's confidential information or (e) is disclosed
without similar restrictions to third parties generally by the party owning the
confidential information.  If confidential information is required to be
disclosed pursuant to a requirement of a governmental authority, such
confidential information may be disclosed pursuant to such requirement so long
as the party required to disclose the information provides the other party with
timely prior notice of such requirement and coordinates with such other party in
an effort to limit the nature and scope of such required disclosure.  All
confidential information that is subject to this Section 12 must be, if in
written form when received from the other party, marked or identified as
confidential and, if in oral or visual form when received from the other party,
identified in advance as confidential.  Notwithstanding the foregoing, the
following information will be deemed the confidential information of PointCast
without the necessity of marking or identifying it as such: (i) information
developed by PointCast or PCN, (ii) information on performance and utilization
of PCN, and (iii) information in whatever form relating to (A) the design,
functionality, operational methods, or coding of any PointCast software,
including, without limitation, any complete or partial object or source code
versions of such software, (B) the design elements and tradeoffs, system
components and configurations, and operating and performance characteristic of
the current operating environment of PCN (as it may change over a period of
time) and/or the PointCast Texas Data Center, and (C) the collection,
transmission, and analysis of statistical information from the PCN Client or
PointCast server software.

13.  TERMINATION.  In the event that either party materially or repeatedly
     -----------
defaults in the performance of any of its duties or obligations hereunder, (a)
which default, if of a non-monetary nature, is not substantially cured within
thirty (30) days after written notice is given to the defaulting party
specifying the default, or with respect to those defaults that cannot reasonably
be cured within thirty (30) days, should the defaulting party fail to proceed
within thirty (30) days to commence curing the default and thereafter to proceed
with all reasonable diligence to substantially cure the default, or (b) which
default, if of a monetary nature, is not cured within thirty (30) days after
written notice is given to the defaulting party specifying the default, the
party not in default may, by giving written notice thereof to the defaulting
party, terminate this Agreement as of a date specified in such notice of
termination. Notwithstanding the foregoing, any Work Order hereunder may be
terminated in accordance with the terms of a Work Order. Upon expiration or
termination of this Agreement or any Work Order for any reason, EDS will cease
to perform the EDS Services for PointCast, or the EDS Services under such Work
Order (as appropriate), and PointCast will pay to EDS all sums due to EDS as a
result of EDS Services performed prior to such termination (prorated as
appropriate). Upon expiration or any other termination of this Agreement, EDS
will return to PointCast or destroy, at PointCast's option, all copies of all
materials, including software, and all equipment provided to EDS hereunder by
PointCast and shall erase from computer memory any copies of such materials,
including software, residing thereon. If PointCast directs that any materials
are to be destroyed, EDS shall certify in writing that such materials have been
destroyed. The provisions of Sections 1, 6, 10, 11, 12, 14, 15, 16, 20, 23, and
24 as well as any payment obligations for payments due and payable as of the
date of termination shall survive the expiration or other termination of this
Agreement.

14.  INDEMNITIES.
     -----------
 
(a)  Subject to Section 14(d) , EDS and PointCast (each, as an indemnifying
     party, the "Indemnitor") each agree to indemnify and defend the other party
     (each, as an indemnified party, the "Indemnitee") and hold the Indemnitee
     harmless from any and all claims, actions, damages, liabilities, costs and
     expenses, including but not limited to reasonable attorneys' fees and
     expenses (collectively, "Costs"), arising out of, under or in connection
     with (i) any claim for rent or utilities at any location where the
     Indemnitor is financially responsible under this Agreement for such rent or
     utilities, (ii) any claim for taxes, wages, benefits or third party fees
     for which the Indemnitor is



                                                                               4
<PAGE>
 
     financially responsible under this Agreement or (iii) the death or personal
     injury, or loss or damage to the property, of the Indemnitee or its
     employees or representatives caused by the negligent act or omission or
     willful misconduct of the Indemnitor; and, (iv) in addition EDS agrees to
     indemnify and defend and hold harmless PointCast from any costs of EDS or
     its officers, directors, employees, agents, or representatives arising out
     of or relating to the termination of this Agreement in accordance with its
     terms or the termination of any other agreements or employment
     relationships as may be entered into by EDS which results from such
     termination of this Agreement.

(b)  Subject to Section 14(d), EDS and PointCast each agree to defend the
     Indemnitee against any action to the extent that such action is based upon
     a claim that the software (other than third party software), Technology or
     confidential information provided by the Indemnitor, or any part thereof,
     (i) infringes a copyright perfected under United States statute, (ii)
     infringes a patent granted under United States law or (iii) constitutes an
     unlawful disclosure, use or misappropriation of another party's trade
     secret or confidential information.  The Indemnitor will bear the expense
     of such defense and pay any Costs that are attributable to such claim
     finally awarded by a court of competent jurisdiction.  Neither EDS nor
     PointCast will be liable to the other for claims of indirect or
     contributory infringement.

(c)  Subject to Section 14(d), PointCast will defend EDS from any action by
     third parties to the extent that such action is based on a claim of
     infringement of the literary property of another, libel, indecency, false
     light, misrepresentation, invasion of privacy or misappropriations of image
     or personality rights, arising out of, under or in connection with any
     claims relating to (Ii) the provision, use or distribution of the content
     via PCN over the Internet from the PointCast Texas Data Center where
     transmission of such content was authorized by PointCast, whether such
     content is of an editorial, advertising or other nature, (ii) (iii)
     statements or other materials made or made available on PCN by Viewers, by
     PointCast's customers or by others to whom such content is linked at the
     request of PointCast.  PointCast will bear the expense of such defense and
     pay any Costs that are attributable to such claim finally awarded by a
     court of competent jurisdiction.

(d)  Each of the above indemnities is conditioned upon the Indemnitor having
     received full and prompt notice in writing of the claim and the Indemnitee
     allowing the Indemnitor to fully direct the defense or settlement of such
     claim.  The Indemnitor will not be responsible for any settlement or
     compromise made without its consent.

15.  LIABILITY.  In the event that either party is liable to the other for any
     ---------
     matter relating to or arising in connection with this Agreement except for
     PointCast's obligations of payment pursuant to Section 7 hereof, whether
     based upon an action or claim in contract, equity, negligence, intended
     conduct or otherwise, the amount of damages recoverable against a party for
     all events, acts or omissions will not exceed, in the aggregate, [*] to be
     paid by PointCast under this Agreement in the [*] preceding such claim, or
     if the claim occurs during the first year of the Agreement, then [*] to be
     paid by PointCast in the [*] of this Agreement. In no event will the
     measure of damages include, nor will either party be liable for, any
     amounts for loss of profits, income or savings or indirect, consequential,
     incidental or punitive damages of any party, including third parties.
     Further, no cause of action may be asserted against either parties later
     than [*] following the date after the date on which the cause of action
     will have accrued. EDS and PointCast expressly acknowledge that the
     limitations contained in this Section 15 have been the subject of active
     and extensive negotiation between the parties and represent the parties'
     agreement based upon the level of risk to EDS associated with the
     performance of the EDS Services and the payments provided hereunder to EDS
     for such performance. Nothing in this Section 15 shall apply to any
     liability for breach of confidentiality obligations or to any indemnity

SCHEDULE A EDS SERVICES
- -----------------------

     EDS has agreed to create a data center for the purpose of hosting the PCN
in Plano, Texas (the "PointCast Texas Data Center").  PointCast has informed EDS
that the data center is configured to be capable of handling approximately two
hundred and Fifty thousand (250,000) PCN Clients each receiving one or more
updates of customized news or information from PCN per 24 hour day when
configured as PCN's current environment.  The PCN is an integrated client/server
system that provides updated current information on a variety of topics to users
of the system via the Internet.  The system allows each user to customize,
within limits, the frequency of those operations.

     Obligations of EDS and Pointcast under this Work Order will expire three
years from the date of acceptance under this Work Order.

1.   PCN CURRENT ENVIRONMENT.
     -----------------------

The attached system block diagram shows the major components in the PCN:

Figure 1: The PCN Network

2.   EDS OBLIGATIONS
     ---------------

     The PointCast Texas Data Center will provide secure hosting for the
PointCast application and data servers in a high security environment as is
standard for all EDS Information Processing Centers.  It will also provide a
high-bandwidth communications link to the public Internet that is monitored at
all times with sophisticated wide area network management tools.  The network is
supported and managed by EDS network specialists, and an operations and systems
administration staff will maintain the PointCast servers and provide all
technical and support resources required to resolve any technical issues or
failures of equipment.  EDS is to provide constant operation of the PointCast
servers, all in accordance with the description of services to be performed by
EDS, which is attached to this Work Order as Attachment 1, Schedule A and is
incorporated herein by reference.  EDS shall perform the tasks in this Schedule
A and in Attachment 1, Schedule A, attached to this Work Order, as part of
normal operations for the monthly fee under this Work Order.  Such tasks shall
not be subject to any additional charges.


                                                                               1
<PAGE>
 
 
                                  WORK ORDER 1


     EDS will, at EDS' sole cost and expense, purchase, maintain and support the
hardware, software and communications resources described in Attachment 2,
Schedule A B attached to this Work Order.  With the exception of any equipment
provided by PointCast or a third party, which shall be the sole property of
PointCast or such third party, EDS will own all equipment of the PointCast Texas
Data Center.

     EDS will, at EDS' sole cost and expense, provide such office space,
equipment and furnishings to PointCast's personnel as is reasonable required
under this Work Order.  EDS will derive from PCN and deliver to PointCast
certain advertising statistics to be described more fully in the implementation
plan under this Work Order.  In accordance with EDS' standard practice, the
PointCast Texas Data Center will be provided with multilayered uninterrupted
power.

3.   CHANGE ORDER PROCEDURES.
     -----------------------

     PointCast may request changes in the operation or services provided under
this Work Order in order to meet the changing needs of PCN.  Such requests shall
be made in writing.  EDS and PointCast will evaluate the needs and proposed
changes to determine the best course of action.

     EDS will maintain change records implemented by the EDS support team
according to EDS Standard Change Management policies.  System Changes requested
by PCN or implemented by the EDS system administration team will be documented
according to EDS standard Change Management practices.

     Changes that go beyond the scope of the original implementation plan, what
is normal Microsoft NT system administration activities, and that involve work
beyond that described in this Schedule A will be subject to additional fees and
will require a new Work Order.

4.   ACCEPTANCE TESTING.
     ------------------

     Prior to the time PCN is ready to go live in Plano, Texas, the parties will
develop and mutually agree on acceptance criteria and tests for the PointCast
Texas Data Center, which will then be applied and conducted as described in this
paragraph.  Contingent upon the receipt of hardware from suppliers by dams
agreed upon at time of execution of this Work Order, EDS will use best efforts
to make the PointCast Texas Data Center ready for acceptance testing within
fourteen (14) business days after such execution date.  Once the required
equipment is in place and the PointCast software is installed, PointCast will
conduct acceptance tests during the following two-week period to verify that the
PointCast Texas Data Center meets the agreed upon acceptance criteria.  If at
the end of such two-week period, the PointCast Texas Data Center has failed the
acceptance tests, the parties will work together to determine the reasons for
such failure.  The party whose action or inaction is determined to be the cause
of such failure, will, with the cooperation and assistance of the other party,
work to remedy such fault.  If the PointCast Texas Data Center has not passed
the acceptance tests within thirty (30) days after the end of such two-week
period, and if the cause has been attributed to PointCast, PointCast will
immediately begin making the monthly payment to EDS called for by this Work
Order.  If the cause has been attributed to EDS, PointCast shall have the right,
upon written notice to EDS, to terminate this Work Order or this Agreement at
the end of such thirty day period.  Once PointCast has accepted the PointCast
Texas Data Center in accordance with the agreed upon acceptance tests, EDS will
immediately staff its operations team and begin operating the PointCast Texas
Data Center.

5.   PERFORMANCE MONITORING.
     ----------------------

     EDS and PointCast will work together during the implementation of the Data
Center in Plano to mutually agree upon the reports that EDS will prepare and
deliver as part of normal operations to document performance once the PointCast
Texas Data Center has passed the above acceptance tests and gone into operation.
EDS will permit PointCast to track performance and derive statistics via remote
access to the PointCast Texas Data Center.

6.   EDS IMPLEMENTATION AND OPERATIONS TEAMS.

     Prior to the time PCN is ready to go live in Plano, Texas, the parties will
develop and mutually agree on acceptance criteria and tests for the PointCast
Texas Data Center, which will then be applied and conducted as described in this
paragraph.  Contingent upon the receipt of hardware from suppliers by dates
agreed upon at time of execution of this Work Order, EDS will use best efforts
to make the PointCast Texas Data Center ready for acceptance testing within
fourteen (14) business days after such execution date.  Once the required
equipment is in place and the PointCast software is installed, PointCast will
conduct acceptance test during the following two-week period to verify that the
PointCast Texas Data Center meets the agreed upon acceptance criteria.  If at
the end of such two-week period, the PointCast Texas Data Center has failed the
acceptance tests, the parties will work together to determine the reasons for
such failure.  The party whose action or inaction is determined to be the cause
of such failure, will, with the cooperation and assistance of the other party,
work to remedy such fault.  If the PointCast Texas Data Center has not passed
the acceptance tests within thirty (30) days after the end of such two week
period, and if the cause has been attributed to PointCast, PointCast will
immediately begin making the monthly payment to EDS called for by this Work
Order. If the cause has been attributed to EDS, PointCast shall have the right,
upon written notice to EDS, to terminate this Work Order or this Agreement at
the end of such thirty day period.  Once PointCast has accepted the PointCast
Texas Data Center in accordance with the agreed upon acceptance tests, EDS will
immediately staff its operations team and begin operating the PointCast Texas
Data Center.

                      PREFERRED STOCK PURCHASE WARRANT

Warrant No. 1

                           POINTCAST INCORPORATED

                          Void after July 31, 2002

        1.      ISSUANCE.  In consideration of $100, receipt of which is 
hereby acknowledged, this Warrant is issued to Lighthouse Capital Partners, 
L.P. by Pointcast Incorporated, a California corporation (hereinafter with its 
successors called "COMPANY").

        2.      PURCHASE PRICE; NUMBER OF SHARES.  The registered holder of 
this Warrant (the "HOLDER"), commencing on the date hereof, is entitled upon 
surrender of this Warrant with the subscription form annexed hereto duly 
executed, at the principal office of the Company, to purchase form the Company
at a per share (the "Next Purchase Price") equal to the price per share of the
series of Preferred Stock of the Company next issued by the Company after July
1, 1995 (the "Next Preferred Stock") that number of fully paid and 
nonassessable shares of Next Preferred Stock equal to $52,500 divided by the 
Next Purchase Price.  Notwithstanding the foregoing, if the closing sale of 
the Next Preferred Stock has not occurred by December 31, 1995, the Holder 
shall be entitled to purchase from the Company pursuant to the conditions set 
forth above 83,758 shares of Series A Preferred Stock at $0.6268 per share 
(the "Series A Purchase Price").  The Series A Preferred Stock or Next 
Purchase Stock, as the case may be, shall hereafter be known as the "Preferred
Stock," and the Next Purchase Price or Series A Purchase Price, as the case 
may be, shall hereafter be known as the "Purchase Price." Until such time as
this Warrant is exercised in full, or expires, the Purchase Price and the
securities issuable upon exercise of this Warrant are subject to adjustment as
hereinafter provided. The person or persons in whose name or names any
certificate representing shares of Preferred Stock is issued hereunder shall
be deemed to have become the holder of record of the shares represented
thereby as at the close of business on the date this Warrant is exercised with
respect to such shares, whether or not the transfer books of the Company shall
be closed.

        3.      PAYMENT OF PURCHASE PRICE.  The Purchase Price may be paid (i)
in cash or by check, (ii) by the surrender by the Holder to the Company of any
promissory notes or other obligations issued by the Company, with all such notes
and obligations so surrendered being credited against the Purchase Price in an
amount equal to the principal amount thereof plus accrued interest to the date
of surrender, or by (iii) by any combination of the foregoing.

        4.      NET ISSUE ELECTION.  The Holder may elect to receive, without
the payment by the Holder of any additional consideration, shares of Preferred
Stock equal to the value of this Warrant or any portion hereof by the
surrender of this Warrant or such portion to the Company, with the net issue
election notice annexed hereto duly executed, at the principal office of the
Company. Thereupon, the Company shall issue to the Holder such number of fully
paid and nonassessable shares of Preferred Stock as is computed using the
following formula:


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


                                     1 

<PAGE>
 
where:          X=      the number of shares of Preferred Stock to be issued 
                        to the Holder pursuant to this Section 4.

                Y=      the number of shares of Preferred Stock covered by 
                        this Warrant in respect of which the net issues
                        election is made pursuant to the Section 4.
                
                A=      the fair market value of one share of Preferred Stock,
                        as determined in good faith by the Board, as at the time
                        the net issue election is made pursuant to this Section
                        4.
                B=      the Purchase Price in effect under this Warrant at the
                        time the net issue election is made pursuant to this 
                        Section 4.

        5.      PARTIAL EXERCISE. This Warrant may be exercised in part, and
the Holder shall be entitled to receive a new warrant, which shall be dated as
of the date of this Warrant, covering the number of shares in respect of which
this Warrant shall not have been exercised.

        6.      FRACTIONAL SHARES. In no event shall any fractional share of
Preferred Stock be issued upon any exercise of this Warrant. If, upon exercise
of this Warrant as an entirety, the Holder would, except as provided in this
Section 6, be entitled to receive a fractional share of Preferred Stock, then
the Company shall issue the next lower number of full shares of Preferred
Stock. The Company shall pay to the Holder upon exercise the fair market
value, determined by the Board of Directors of the Company in its sole
discretion, acting reasonably, of any fractional share of Preferred Stock
otherwise issuable upon exercise of this Warrant.

        7.      EXPIRATION DATE. This Warrant shall expire at the close of
business on July 31, 2002, and shall be void thereafter. Notwithstanding the
term of this Warrant fixed pursuant to Section 7 hereof and the provisions of
Section 10 below, the right to purchase Preferred Stock as granted herein
shall expire, if not previously exercised, immediately upon the closing of a
merger or consolidation of the Company with or into another corporation when
the Company is not the surviving corporation (other than a merger or
consolidation for the principal purpose of changing the domicile of the
Company), or the sale of all or substantially all of the Company's properties
and assets to any other person (the "Merger"), provided that the price per
share paid in the Merger is equal to or greater than two times the Purchase
Price per share.

The Company shall notify the Holder, in accordance with Section 13 below, of
any Merger, and if the Company fails to deliver such notice, then
notwithstanding anything to the contrary in this Warrant, the rights to
purchase the Company's Preferred Stock shall not expire until ten (10)
business days after the actual receipt by Holder of such notice; provided,
however, that notwithstanding the foregoing, in no event shall the right to
purchase Preferred Stock under this Warrant expire in Section 7 unless the
Holder receives written notice of the proposed merger at least five (5)
business days prior to the closing of such Merger. If such closing does not
take place, the Company shall promptly notify the Holder that such proposed
transaction has been terminated, and the Holder may rescind any exercise of
its purchase rights promptly after such notice of termination of the proposed
transaction if the exercise of the Warrant occurred after the Company notified
the Holder that the Merger was proposed, or if the exercise was otherwise
precipitated by such proposed Merger. In the event of such rescission, the
Warrant will continue to be exercisable on the same terms and conditions
contained herein.

        8.      RESERVED SHARES; VALID ISSUANCE. The Company covenants that it
will at all times from and after the earlier of the closing of the Next
Preferred Stock or December 31, 1995 reserve and keep available such number of
its authorized shares of such Preferred Stock and any Common Stock issuable
upon the conversion thereof, $0.001 par value, of the Company (the "Common
Stock"), free from all preemptive or similar rights therein, as will be
sufficient to permit, respectively, the exercise of this Warrant in full and
the conversion into shares of Common Stock of all shares of Preferred Stock
receivable upon such exercise. The Company further covenants that such shares
as may be issued pursuant to such exercise and/or conversion will, upon
issuance, be duly and validly issued, fully paid and nonassessable and free
from all taxes, liens and charges with respect to the issuance thereof.

                                       2
<PAGE>
 
        9. STOCK SPLITS AND DIVIDENDS. If after the date hereof the Company
shall subdivide the Preferred Stock, by split-up or otherwise, or combine the
Preferred Stock, or issue additional shares of Preferred Stock in payment of a
stock dividend on the Preferred Stock, the number of shares of Preferred Stock
issuable on the exercise of this Warrant shall forthwith be proportionately
increased in the case of a subdivision or stock dividend, or proportionately
decreased in the case of a combination, and the Purchase Price shall forthwith
be proportionately decreased in the case of a subdivision or stock dividend,
or proportionately increased in the case of a combination.

        10. MERGERS AND RECLASSIFICATIONS. Subject in all respects to Section
7 above, if after the date hereof the Company shall enter into any
Reorganization (as hereinafter defined), then, as a condition of such
Reorganization, lawful provisions shall be made, and duly executed documents
evidencing the same from the Company or its successor shall be delivered to
the Holder, so that the Holder shall thereafter have the right to purchase, at
a total price not to exceed that payable upon the exercise of this Warrant in
full, the kind and amount of shares of stock and other securities and property
receivable upon such Reorganization by a holder of the number of shares of
Preferred Stock which might have been purchased by the Holder immediately
prior to such Reorganization, and in any such case appropriate provisions
shall be made with respect to the rights and interest of the Holder to the end
that the provisions hereof (including without limitation, provisions for the
adjustment of the Purchase Price and the number of shares issuable
hereunder) shall thereafter be applicable in relation to any shares of stock
or other securities and property thereafter deliverable upon exercise hereof.
For the purposes of this Section 10, the term "REORGANIZATION" shall include
without limitation any reclassification, capital reorganization or change of
the Preferred Stock (other than as a result of a subdivision, combination or
stock dividend provided for in Section 9 hereof), or any consolidation of the
Company with, or merger of the Company into, another corporation or other
business organization (other than a merger in which the Company is the
surviving corporation and which does not result in any reclassification or
change of the outstanding Preferred Stock), or any sale or conveyance to
another corporation or other business organization of all or substantially all
of the assets of the Company.

        11. CERTIFICATE OF ADJUSTMENT. Whenever the Purchase Price is
adjusted, as herein provided, the Company shall promptly deliver to the holder
a certificate of the Company's chief financial officer setting forth the
Purchase Price after such adjustment and setting forth a brief statement of
the facts requiring such adjustment.

        12. NO RIGHTS AS SHAREHOLDERS. Except as provided herein, this Warrant
does not entitle the Holder to any voting rights as a shareholder of the
Company prior to the exercise if the Holder's rights to purchase Preferred
Stock as provided herein.

        13.     NOTICE OF RECORD DATE, ETC.  In the event of:

                (a) any taking of the Company of a record of the holders of
any class of securities for the purpose of determining the holders thereof who
are entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase, sell or otherwise acquire or dispose of any shares of
stock of any class or any other securities or property, or to receive any
other right;

                (b) any reclassification of the capital stock of the Company,
capital reorganization of the Company, consolidation or merger involving the
Company, or sale or convergence of all or substantially all of its assets; or

                (c) any voluntary or involuntary dissolution, liquidation or
winding-up of the Company;

then and in each such event the Company will provide or cause to be provided
to the Holder a written notice thereof. Such notice shall be provided at least
twenty (20) business days prior to the date specified in such notice on which
any such action is taken.

    14. REPRESENTATIONS, WARRANTIES AND COVENANTS.  This Warrant is issued 
and delivered by the Company and accepted by each Holder on the basis of the 
following representations, warranties and covenants made by the Company:

        A. The Company has all necessary authority to issue, execute and 
deliver this Warrant and to perform its obligations hereunder. This Warrant 
has been duly authorized, issued, executed and delivered by the Company and is
the valid and binding obligation of the Company, enforceable in accordance 
with its terms.

        B. The shares of Preferred Stock issuable upon the exercise of this 
Warrant will be duly authorized and reserved for issuance by the Company and, 
when issued in accordance with the terms hereof, will be validly issued, fully
paid and nonassessable.

        C. This issuance, execution and delivery of this Warrant do not, and 
the issuance of the shares of Preferred Stock upon the exercise of this 
Warrant in accordance with the terms hereof will not, (i) violate or 
contravene the Company's Articles of Incorporation or by-laws, or any law, 
statute, regulation, rule, judgment or order applicable to the Company, (ii) 
violate, contravene or result in a breach or default under any contract, 
agreement or instrument to which the Company is a party or by which the 
Company or any of its assets are bound or (iii) require the consent or 
approval of or the filing of any notice or registration with any person or 
entity.

        D. As long as this Warrant is, or any shares of Preferred Stock issued
upon exercise of this Warrant or any shares of Common Stock issued upon
conversion of such shares of Preferred Stock are, issued and outstanding, the
Company will provide to the Holder the financial and other information
described in that certain Lease Line Schedule No. 01 to Master Equipment Lease
Agreement No. 111 between the Company and Lighthouse Capital Partners, L.P.
dated as of August 10, 1995.

        E. The Company hereby grants to the Holder the Registration Rights 
contained in Section 1 of the Company's Investor Rights Agreement dated as of 
June 4, 1994, so that (i) the shares of Common Stock issuable upon conversion 
of the shares of Preferred Stock issuable upon exercise of this Warrant shall 
be Registrable Securities, and (ii) the Holder shall be a "Holder", for all 
purposes of such Investor Rights Agreement.

    15. AMENDMENT. The terms of this Warrant may be amended, modified or 
waived only with the written consent of the Holder.

    16. REPRESENTATIONS AND COVENANTS OF THE HOLDER. This Preferred Stock 
Purchase Warrant has been entered into by the Company in reliance upon the 
following representations and covenants of the Holder, which by its execution 
hereof the Holder hereby confirms:

        (a) INVESTMENT PURPOSE. The right to acquire Preferred Stock or the 
Preferred Stock issuable upon exercise of the Holder's rights contained herein
will be acquired for investment and not with a view to the sale or 
distribution of any part thereof, and the Holder has no present intention of 
selling or engaging in any public distribution of the same except pursuant to 
a registration or exemption.

        (b) ACCREDITED INVESTOR. Holder is an "accredited investor" within the
meaning of the Securities and Exchange Rule 501 of Regulation D, as presently 
in effect.

        (c) PRIVATE ISSUE. The Holder understands (i) that the Preferred Stock
issuable upon exercise of the Holder's rights contained herein is not 
registered under the 1933 Act or qualified under applicable state securities 
laws on the ground that the issuance contemplated by this Warrant Agreement 
will be exempt from the registration and qualification requirements thereof, 
and (ii) that the Company's reliance on such exemption is predicated on the 
representations set forth in this Section 16.

        (d) DISPOSITION OF HOLDER'S RIGHTS. In no event will the Holder make a
disposition of any of its rights to acquire Preferred Stock or Preferred Stock
issuable upon exercise of such rights unless and until (i)
<PAGE>
 
it shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall nave furnished the Company with an opinion
of counsel (which counsel may either be inside or outside counsel to the
Holder) reasonably satisfactory to the Company and its counsel to the effect
that (A) appropriate action necessary for compliance with the 1933 Act has
been taken, or (B) an exemption from the registration requirements of the 1933
Act is available; provided that the Company shall not require Holder to
provide an opinion of counsel if the transfer is to an affiliate Holder or if
there is no material question as to the availability of current information as
referenced in Rule 144(c), Holder represents that it has complied with Rule
144(d) and (e) in reasonable detail, the selling broker represents that it has
complied with Rule 144(f), and the Company is provided with a copy of Holder's
notice of proposed sale. Notwithstanding the foregoing, the restrictions
imposed upon the transferability of any of its rights to acquire Preferred
Stock or Preferred Stock issuable on the exercise of such rights do not apply
to transfers from the beneficial owner of any of the aforementioned securities
to its nominee or from such nominee to its beneficial owner, and shall
terminate as to any particular share of Preferred Stock when (1) such security
shall have been effectively registered under the 1933 Act and sold by the
holder thereof in accordance with such registration or (2) such security shall
have been sold without registration in compliance with Rule 144 under the 1933
Act, or (3) a letter shall have been issued to the Holder at its request by
the staff of the Securities and Exchange Commission or a ruling shall have
been issued to the Holder at its request by such Commission stating that no
action shall be recommended by such staff or taken by such Commission, as the
case may be, if such security is transferred without registration under the
1933 Act in accordance with the conditions set forth in such letter or ruling
and such letter or ruling specifies that no subsequent restrictions or
transfer are required. Whenever the restrictions imposed hereunder shall
terminate, as hereinabove provided, the Holder or holder of a share of
Preferred Stock then outstanding as to which such restrictions have terminated
shall be entitled to receive from the Company, without expense to such holder,
one or more new certificates for the Warrant or for such shares of Preferred
Stock not bearing any restrictive legend.

                (e)     FINANCIAL RISK.  The Holder has such knowledge and 
experience in financial and business matters as to be capable of evaluating the
merits and risks of its investment and has the ability to bear the economic 
risks of its investments.

                (f) RISK OF NO REGISTRATION. The Holder understands that if
the Company does not register with the Securities and Exchange Commission
pursuant to Section 12 of the 1933 Act, or file reports pursuant to Section
15(d) of the Securities Exchange Act of 1934 (the "1934 Act"), or of a
registration statement covering the securities under the 1933 Act is not in
effect when it desires to sell (i) the rights to purchase Preferred Stock
pursuant to this Warrant Agreement, or (ii) the Preferred Stock issuable upon
exercise of the right to purchase, it may be required to hold such securities
for an indefinite period. The Holder also understands that any sale of the
rights of the Holder to purchase Preferred Stock which might be made by it in
reliance upon Rule 144 under the 1933 Act may be made only in accordance with
the terms and conditions of that Rule.

        17.     NOTICE TRANSFERS, ETC.

                A. Any notice or written communication required or permitted
to be given to the Holder may be given by mail or delivered to the Holder at
the address most recently provided by the Holder to the Company.

                B. Subject to compliance with applicable federal and state
securities laws, and to the Holder's obtaining the Company's prior written
consent, which shall not be unreasonably withheld, this Warrant may be
transferred by the Holder with respect to any or all of the shares purchasable
hereunder. Upon surrender of this Warrant to the Company, together with the
assignment notice annexed hereto duly executed, for transfer of this Warrant
as an entirety by the Holder, the Company shall issue a new warrant of the
same denomination to the assignee. Upon surrender of this Warrant to the
Company, together with the assignment hereof properly endorsed, by the Holder
for transfer with respect to a portion of the shares of Preferred Stock
purchasable hereunder, the Company shall issue a new warrant to the assignee,
in such denomination as shall be requested by the Holder hereof, and shall
issue to such Holder a new warrant covering the number of shares in respect of
which this Warrant shall not have been transferred.

                                      5
<PAGE>
 
                C.  In case this Warrant shall be mutilated, lost, stolen or 
destroyed, the Company shall issue a new warrant of like tenor and denomination 
and deliver the same (i) in exchange and substitution for and upon surrender and
cancellation of any mutilated Warrant, or (ii) in lieu of any Warrant lost, 
stolen or destroyed, upon receipt of an affidavit of the Holder or other 
evidence reasonably satisfactory to the Company of the loss, theft or 
destruction of such Warrant.

        18.     NO IMPAIRMENT. The Company will not, by amendment of its 
Articles of Incorporation or through any reclassification, capital 
reorganization, consolidation, merger, sale or conveyance of assets, 
dissolution, liquidation, issue or sale of securities or any other voluntary 
action, avoid or seek to avoid the observance of performance of any of the terms
of this Warrant, but will at all times in good faith assist in the carrying out 
of all such terms and in the taking of all such action as may be necessary or 
appropriate in order to protect the rights of the Holder.

        19.     GOVERNING LAW. The provisions and terms of this Warrant shall 
be governed by and construed in accordance with the internal laws of the State 
of California.

        20.     SUCCESSORS AND ASSIGNS. This Warrant shall be binding upon the 
Company's successors and assigns and shall inure to the benefit of the Holder's 
successors, legal representatives and permitted assigns.

        21.     BUSINESS DAYS. If the last or appointed day for the taking of 
any action required or the expiration of any right granted herein shall be a 
Saturday or Sunday or a legal holiday in California, then such action may be 
taken or right may be exercised on the next succeeding day which is not a 
Saturday or Sunday or such a legal holiday.

        22.     QUALIFYING PUBLIC OFFERING. If the Company shall effect a firm 
commitment underwritten public offering of shares of Common Stock which results 
in the conversion of the Preferred Stock into Common Stock pursuant to the 
Company's Articles of Incorporation in effect immediately prior to such
offering, then, effective upon such conversion, this Warrant shall change from
the right to purchase shares of Preferred Stock to the right to purchase shares
of Common Stock, and the Holder shall thereupon have the right to purchase, at a
total price equal to that payable upon the exercise of this Warrant in full, the
number of shares of Common Stock which would have been receivable by the Holder
upon the exercise of this Warrant for shares of Preferred Stock immediately
prior to such conversion of such shares of Preferred Stock into shares of Common
Stock, and in such event appropriate provisions shall be made with respect to
the right and interest of the Holder to the end that the provisions hereof
(including, without limitation, provisions for the adjustment of the Purchase
Price and of the number of shares purchasable upon exercise of this Warrant)
shall thereafter be applicable to any shares of Common Stock deliverable upon
the exercise hereof.

        23.     VALUE; TAX INDEMNITY. The Company and the Holder agree that the 
value of this Warrant on the date of grant is $100. The Company hereby agrees to
pay, indemnify and hold the Holder harmless from, and to reimburse the Holder 
for, all taxes, penalties, fines, additions to tax or interest thereon 
(collectively, "Taxes") imposed on, incurred by or asserted against the Holder 
by any Federal, state or local taxing authority to the extent resulting from 
income attributable to such Holder due to warrant accretion expense incurred by 
the Company. The Company further agrees that, with respect to any payment or 
indemnity hereunder, such payment or indemnity shall include any amount 
necessary to hold the recipient of the payment or indemnity harmless on a net 
aggregate after tax basis from all Taxes required to be paid by the recipient 
with respect to such payment or indemnity under the laws of any Federal, state 
or local taxing authority. Any payment or indemnity payable by the Company 
pursuant to this Section 23 shall be payable five (5) days prior to the time
that the Taxes giving rise to such payment nor indemnity become payable.

              (i.e., not a mere recapitalization, reincorporation for the
              purpose of changing corporate domicile, 
<PAGE>
 
              or similar transaction) (the "Acquisition"), regardless of the
              form of the transaction (e.g., merger, consolidation, exclusive
              license, sale or lease of assets or sale of stock), the Company
              shall give the Holder not less than fifteen (15) business days

              provided to shareholders of the Company at such time and from time
              to time during the pendency of the Acquisition, including (but not
              limited to) the proposed price to be paid in the proposed
              Acquisition; the Holder shall have the right to exercise same on
              or prior to the record date of shareholders eligible to vote (or
              otherwise approve) with respect to the proposed Acquisition; if
              the Warrant is not exercised on or prior to such record date, the
              Warrant shall expire upon the occurrence of the consummation of
              the Acquisition, provided that if the Acquisition is not
              consummated, then the Holder shall be entitled to revoke the
              exercise of this Warrant pursuant to the operation of this Section
              1(a).

     2.  EXERCISE OF WARRANT

     The purchase rights represented by this Warrant are exercisable by the
registered holder hereof, in whole or in part, at any time and from time to time
at or prior to the Expiration Time by the surrender of this Warrant and the
Notice of Exercise form attached hereto duly executed to the principal executive
office of the Company at the address set forth on the signature page hereof (or
such other office or agency of the Company as it may designate by notice in
writing to the registered holder hereof at the address of such holder appearing
on the books of the Company), and upon payment of the Exercise Price for the
shares thereby purchased by cash, check or wire transfer or, at the election of
the Warrantholder, may be made on a "net exercise" basis, in which event the
Company shall issue the Warrantholder a number of shares of Common Stock
computed using the following formula:
 
                                 Y = X(A-B)/A

Where:
 
     X  =  the number of equal shares of Common Stock for which this Warrant is
           exercisable;
 
     Y  =  the number of shares of Common Stock to be issued to the Holder;
 
     A  =  the Fair Market Value (as defined below) of one share of the
           Company's Common Stock on the date of conversion of this Warrant; and
           
     B  =  the Exercise Price for one share of the Company's Common Stock under
           this Warrant.

                                      -2-
<PAGE>
 
     If the above calculation results in a negative number, then no shares of
Warrant Stock shall be issued or issuable upon conversion of this Warrant.

     "Fair Market Value" of a share of Common Stock shall mean:

     (a)  if this Warrant is exercised (i) immediately prior to a Qualified IPO,
          and (ii) if the Company's Registration Statement on Form S-1 or SB-2
          (or successor or equivalent forms) relating to such public offering
          has been declared effective by the Securities and Exchange Commission,
          then the Fair Market Value per share shall be the price per share to
          the public as specified in the final prospectus with respect to the
          offering;

     (b)  if this Warrant is exercised after the consummation of a Qualified
          IPO, then:

          (i)  if traded on a securities exchange, the Fair Market Value per
               share of Common Stock shall be deemed to be the average of the
               closing sales prices of the Company's Common Stock over a ten
               (10) day trading period (or for such shorter period as the
               Company's Common Stock may have been trading) ending three (3)
               days before the Exercise Date, or

          (ii) if traded over-the-counter, the Fair Market Value per share of
               Common Stock shall be deemed to be the average of the prices of
               the Company's Common Stock quoted on The Nasdaq Stock Market,
               Inc. (or NASD bulletin board or any similar system) over the ten
               (10) day trading period (or for such shorter period as the
               Company's Common Stock has been trading) ending three (3) days
               before the Exercise Date; or

     (c)  if this Warrant is exercised prior to a Qualified IPO (except as
          provided in clause (a) above), the Fair Market Value per share of
          Common Stock shall be equal to an amount determined in good faith by
          the Company's Board of Directors, but shall in no event be less than
          the actual sale price per share in the Company's latest financing.

     Upon exercise of this Warrant in accordance with this Section 2, the holder
of this Warrant shall be entitled to receive from the Company a stock
certificate in proper form representing the number of shares of Warrant Stock so
purchased, and a new Warrant in substantially identical form and dated as of
such exercise for the purchase of that number of shares of Warrant Stock equal
to the difference, if any, between the number of shares of Warrant Stock subject
hereto and the number of shares of Warrant Stock as to which this Warrant is so
exercised.

     3.  CONVERSION OF WARRANT

     The Holder shall have the right to convert this Warrant, in whole or in
part, at any time (including, but not limited to, the occurrence of an
Acquisition of the Company) and from time to time at or prior to the Expiration
Time by the payment of the Exercise Price (as hereinafter defined), and
surrender of this Warrant and the Notice of Conversion form attached hereto duly
executed to the principal executive office of the Company at the address set
forth on the signature page hereof (or such other office or agency of the
Company as it may designate by notice in writing to the Holder at the address of
such Holder appearing on the books of the Company), into shares of Warrant Stock
as 

                                      -3-
<PAGE>
 
provided in this Section 3. Payment of the Exercise Price may be made by cash,
check or wire transfer or, at the election of the Warrantholder, may be made on
a "net exercise" basis, in which event the Company shall issue the Warrantholder
a number of shares of Common Stock computed using the formula set forth in
Section 2.

     Upon conversion of this Warrant in accordance with this Section 3, the
Holder hereof shall be entitled to receive a certificate for the number of
shares of Warrant Stock determined in accordance with the foregoing, and a new
Warrant in substantially identical form and dated as of such conversion for the
purchase of that number of shares of Warrant Stock equal to the difference, if
any, between the number of shares of Warrant Stock subject hereto and the number
of shares of Warrant Stock as to which this Warrant is so converted.

     4.  ISSUANCE OF SHARES; NO FRACTIONAL SHARES OR SCRIP

     Certificates for shares purchased hereunder or issuable upon conversion
hereof shall be delivered to the Holder promptly after the date on which this
Warrant shall have been exercised or converted in accordance with the terms
hereof.  The Company hereby represents and warrants that all shares of Warrant
Stock which may be issued upon the exercise or conversion of this Warrant will,
upon such exercise or conversion, be duly and validly authorized and issued,
fully paid and nonassessable and free from all liens and encumbrances in respect
of the issuance thereof (other than liens or encumbrances created by or imposed
upon the Holder of the Warrant Stock).  The Company agrees that the shares so
issued shall be and shall for all purposes be deemed to have been issued to such
Holder as the record owner of such shares as of the close of business on the
date on which this Warrant shall have been exercised or converted in accordance
with the terms hereof.  No fractional shares or scrip representing fractional
shares shall be issued upon the exercise or conversion of this Warrant.  With
respect to any fraction of a share called for upon the exercise or conversion of
this Warrant, an amount equal to such fraction multiplied by the Fair Market
Value of a share of Warrant Stock on the date of exercise or conversion shall be
paid in cash or check to the Holder.

     5.  CHARGES, TAXES AND EXPENSES

     Issuance of certificates for shares of Warrant Stock upon the exercise or
conversion of this Warrant shall be made without charge to the Holder for any
issue or transfer tax or other incidental expense in respect of the issuance of
such certificate, all of which taxes and expenses shall be paid by the Company,
and such certificates shall be issued in the name of the Holder or in such name
or names as may be directed by the Holder provided, however, that in the event
certificates for shares of Warrant Stock are to be issued in a name other than
the name of the Holder, this Warrant when surrendered for exercise or conversion
shall be accompanied by the Assignment Form attached hereto duly executed by the
Holder.

     6.   RIGHTS AS SHAREHOLDERS

     No Holder of this Warrant, as such, shall be entitled to vote upon any
matter submitted to shareholders at any meeting thereof, or to receive notice of
meetings, or be deemed the holder of 

                                      -4-
<PAGE>
 
Common Stock until this Warrant shall have been exercised or converted in whole
or in part and the Warrant Stock purchasable upon such exercise shall have
become deliverable, as provided herein.

     7.  COMPANY'S RIGHT OF FIRST REFUSAL PRIOR TO WARRANT EXERCISE

     Before the Warrant may be sold or otherwise transferred by the Holder or
any transferee (including transfer by gift or operation of law), the Company or
its assignee(s) shall have a right of first refusal to purchase the Warrant on
the terms and conditions set forth in this Section 7 (the "Right of First
Refusal").

          (a) Notice of Proposed Transfer.  The Holder shall deliver to the
              ---------------------------                                  
              Company a written notice (the "Notice") stating: (i) the Holder's
              bona fide intention to sell or otherwise transfer the Warrant;
              (ii) the name of the proposed purchaser or other transferee
              ("Proposed Transferee"); and (iii) the bona fide cash price or
              other consideration for which the Holder proposes to transfer the
              Warrant (the "Offered Price"), and the Holder shall offer the
              Warrant at the Offered Price to the Company or its assignee(s),
              provided that any such assignee is a securityholder of the
              Company.

          (b) Exercise of Right of First Refusal.  At any time within 20 days
              ----------------------------------                             
              after receipt of the Notice, the Company or its assignee(s) may,
              by giving written notice to the Holder, elect to purchase the
              Warrant proposed to be transferred to the Proposed Transferee, at
              the purchase price determined in accordance with subsection (c)
              below.

          (c) Purchase Price.  The purchase price ("Purchase Price") for the
              --------------                                                
              Warrant purchased by the Company or its assignee(s) under this
              Section shall be the Offered Price. If the Offered Price includes
              consideration other than cash, the cash equivalent value of the
              non-cash consideration shall be determined in good faith by the
              Board of Directors of the Company.

          (d) Payment.  Payment of the Purchase Price shall be made in cash (by
              -------                                                          
              check) within 15 days of the Company's written notice to the
              Holder pursuant to Section 7(b).

          (e) Holder's Right to Transfer.  If the Warrant proposed in the Notice
              --------------------------                                        
              to be transferred to a given Proposed Transferee is not purchased
              by the Company or its assignee(s) as provided in this Section,
              then the Holder may sell or otherwise transfer such Warrant to
              that Proposed Transferee at the Offered Price or at a higher
              price, provided that such sale or other transfer is consummated
              within 90 days after the date of the Notice and provided further
              that any such sale or other transfer is effected in accordance
              with any applicable securities laws and the Proposed Transferee
              agrees in writing that the provisions of this Section 7 shall
              continue to apply to the Warrant in the hands of such Proposed
              Transferee. If the Warrant described in the Notice is not
              transferred to the Proposed Transferee 

                                      -5-
<PAGE>
 
              within such period, a new Notice shall be given to the Company,
              and the Company or its assignees shall again be offered the Right
              of First Refusal before the Warrant held by the Holder may be sold
              or otherwise transferred.

          (f) Exception for Certain Transfers.  The Warrant may be transferred
              -------------------------------                                 
              without the Company being offered the Right of First Refusal in
              the following transactions; provided that any Transferee shall
              agree to the terms of this Section 7 as to the Warrant:

              (1) A Holder's transfer of the Warrant in whole or in part to the
                  Company or to any shareholder of the Company.

              (2) A Holder's transfer of the Warrant in whole or in part to a
                  person who, at the time of such transfer, is an officer or
                  director of the Company.

              (3) A Holder's transfer of the Warrant in whole or in part
                  pursuant to and in accordance with the terms of any merger,
                  consolidation, reclassification of shares or capital
                  reorganization of the corporate shareholder, or pursuant to a
                  sale of all or substantially all of the stock or assets of a
                  corporate shareholder.

              (4) A transfer by a Holder which is a limited or general
                  partnership to any or all of its partners or former partners
                  or any professional employee (or entity of which such
                  employees are the beneficiaries) of such partnership.

              (5) A transfer by a Holder which is a corporation to any parent
                  company of the Holder, or any majority-owned subsidiary of
                  such parent company, provided that any such transferee does
                  not derive a majority of its revenues from products or
                  services that compete directly with products or services from
                  which the Company derives a majority of its revenues.

              (6) Any transfer by a Holder which is a limited liability company
                  to any or all of its members or former members or any
                  professional employee (or entity of which such employees are
                  the beneficiaries) of such limited liability company.

     Any such transfer shall be made upon surrender of this Warrant together
with the Assignment Form attached hereto properly endorsed.

          (g) Termination of Right of First Refusal.  The Right of First Refusal
              -------------------------------------                             
              shall terminate (i) as to any Warrant Stock acquired upon the
              exercise or conversion of the Warrant in whole or in part, on the
              effective date of such exercise or conversion and (ii) as to any
              portion of the Warrant not previously exercised or converted, on
              the date 180 days after the date of the final prospectus (the
              "Final Prospectus") 

                                      -6-

              contained in a registration statement filed with and declared
              effective by the Securities and Exchange Commission under the
              Securities Act relating to the initial public offering by the
              Company of its capital stock.

     8.   MARKET STAND-OFF AGREEMENT

     The Holder hereby agrees in connection with any registration of the
Company's securities (other than a registration of securities in a Rule 145
transaction or with respect to an employee benefit plan), upon request of the
Company or the underwriters managing any underwritten offering of the Company's
securities, not to sell, make any short sale of, loan, pledge (or otherwise
encumber or hypothecate), grant any option for the purchase of, or otherwise
directly or indirectly dispose of any shares or other securities of the Company
(other than those included in the registration) without the prior written
consent of the Company and such managing underwriters for such period of time,
not to exceed 180 days following the date of the Final Prospectus, as the Board
of Directors establishes pursuant to its good faith negotiations with such
managing underwriters; provided, however, that the Holder shall not be subject
to such market stand-off unless the officers and directors of the Company who
own stock of the Company shall also be bound by such restrictions. The Company
may impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such 180-day period.

     9.  EXCHANGE AND REGISTRY OF WARRANT

     This Warrant is exchangeable, upon the surrender hereof by the Holder at
the above-mentioned office or agency of the Company, for a new Warrant in
substantially identical form and dated as of such exchange.  The Company shall
maintain at the above-mentioned office or agency a registry showing the name and
address of the registered Holder of this Warrant.  This Warrant may be
surrendered for exchange, transfer, exercise or conversion, in accordance with
its terms, at such office or agency of the Company, and the Company shall be
entitled to rely in all respects, prior to written notice to the contrary, upon
such registry.

     10.  LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT

     On receipt by the Company of evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant, and in
case of any such loss, theft or destruction of this Warrant, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of any such mutilation, on surrender and cancellation of such
Warrant, the Company will execute and deliver to the Holder, in lieu thereof, a
new warrant in substantially identical form, dated as of such cancellation and
reissuance.

     11.  SATURDAYS, SUNDAYS AND HOLIDAYS

     If the last or appointed day for the taking of any action or the expiration
of any right required or granted herein shall be a Saturday or a Sunday or shall

                                      -7-
<PAGE>
 
     12.  ADJUSTMENTS

     The type and number of securities of the Company issuable upon exercise of
this Warrant and the Exercise Price are subject to adjustment as set forth
below:

          (a) If the Company shall at any time declare a dividend payable in
              shares of Common Stock, then the Warrantholder, upon exercise of
              this Warrant after the record date for the determination of
              holders of Common Stock entitled to receive such dividend, shall
              be entitled to receive upon exercise of this Warrant, in addition
              to the number of shares of Common Stock as to which this Warrant
              is exercised, such additional shares of Common Stock as such
              holder would have received had this Warrant been exercised
              immediately prior to such record date.

          (b) If the Company shall at any time effect a recapitalization or
              reclassification of such character that the shares of Common Stock
              shall be changed into or become exchangeable for a larger or
              smaller number of shares, then upon the effective date thereof the
              number of shares of Common Stock which the Warrantholder shall be
              entitled to purchase upon exercise of this Warrant shall be
              increased or decreased, as the case may be, in direct proportion
              to the increase or decrease in the number of shares of Common
              Stock by reason of such recapitalization or reclassification, and
              the Exercise Price shall be, in the case of an increase in the
              number of shares, proportionately decreased and, in the case of a
              decrease in the number of shares, proportionately increased.

          (c) If the Company shall at any time distribute to holders of Common
              Stock cash, evidences of indebtedness or other securities or
              assets (other than cash dividends or distributions payable out of
              earned surplus) then, in any such case, the Warrantholder shall be
              entitled to receive, upon exercise of this Warrant, with respect
              to each share of Common Stock issuable upon such exercise, the
              amount of cash or evidences of indebtedness or other securities or
              assets which such holder would have been entitled to receive with
              respect to each such share of Common Stock as a result of the
              happening of such event had this Warrant been exercised
              immediately prior to the record date or other date fixing
              stockholders to be affected by such event.

          (d) If at any time on or after the date hereof the Company shall
              subdivide its outstanding shares of Common Stock into a greater
              number of shares, the Warrant Price in effect immediately prior to
              such subdivision shall thereby be proportionately reduced and the
              number of shares receivable upon exercise of the Warrant shall
              thereby be proportionately increased; and, conversely, if at any
              time on or after the date hereof the outstanding number of shares
              of Common Stock shall be combined into a smaller number of shares,
              the Warrant Price in effect immediately prior to such combination
              shall thereby be proportionately increased 

                                      -8-
<PAGE>
 
              and the number of shares receivable upon exercise of the Warrant
              shall thereby be proportionately decreased.

          (e) As used in this Warrant the term "Exercise Price" shall mean the
              purchase price per share specified in this Warrant until the
              occurrence of an event stated in subsections (b) or (d) of this
              Section 12 and thereafter shall mean said price as adjusted from
              time to time in accordance with the provisions of said
              subsections. No adjustment made pursuant to any provision of this
              Section 12 shall have the effect of increasing the total
              consideration payable upon exercise of this Warrant in respect of
              all the Common Stock as to which this Warrant may be exercised.

          (f) In the event that at any time, as a result of an adjustment made
              pursuant to this Section 12, the Warrantholder shall, upon
              exercise of this Warrant, become entitled to receive shares and/or
              other securities or assets (other than Common Stock) then,
              wherever appropriate, all references herein to shares of Common
              Stock shall be deemed to refer to and include such shares and/or
              other securities or assets; and thereafter the number of such
              shares and/or other securities or assets shall be subject to

     1.   TERM

          (a) Termination and Expiration.  If not earlier exercised, the Warrant
              --------------------------                                        
              shall expire on the date (the "Expiration Date") that is the

              firmly underwritten public offering pursuant to the Securities Act
              of 1933, as amended (the "Securities Act"), by the Company of its

              "Qualified IPO") and (ii) 60 months after the date first set forth
              above.

          (b) Exceptions.  Notwithstanding the foregoing, in the event the
              ----------                                                  
              Company is proposed to be acquired in a bona fide transaction
              (i.e., not a mere recapitalization, reincorporation for the
              purpose of changing corporate domicile, 
<PAGE>
 
              or similar transaction) (the "Acquisition"), regardless of the
              form of the transaction (e.g., merger, consolidation, exclusive
              license, sale or lease of assets or sale of stock), the Company
              shall give the Holder not less than fifteen (15) business days
              notice of the record date for determining the shareholders of the
              Company entitled to vote on (or otherwise approve) the
              Acquisition; the Company shall provide the Holder with all
              information with respect to the Acquisition that is otherwise
              provided to shareholders of the Company at such time and from time
              to time during the pendency of the Acquisition, including (but not
              limited to) the proposed price to be paid in the proposed
              Acquisition; the Holder shall have the right to exercise same on
              or prior to the record date of shareholders eligible to vote (or
              otherwise approve) with respect to the proposed Acquisition; if
              the Warrant is not exercised on or prior to such record date, the
              Warrant shall expire upon the occurrence of the consummation of
              the Acquisition, provided that if the Acquisition is not
              consummated, then the Holder shall be entitled to revoke the
              exercise of this Warrant pursuant to the operation of this Section
              1(a).

     2.  EXERCISE OF WARRANT

     The purchase rights represented by this Warrant are exercisable by the
registered holder hereof, in whole or in part, at any time and from time to time
at or prior to the Expiration Time by the surrender of this Warrant and the
Notice of Exercise form attached hereto duly executed to the principal executive
office of the Company at the address set forth on the signature page hereof (or
such other office or agency of the Company as it may designate by notice in
writing to the registered holder hereof at the address of such holder appearing
on the books of the Company), and upon payment of the Exercise Price for the
shares thereby purchased by cash, check or wire transfer or, at the election of
the Warrantholder, may be made on a "net exercise" basis, in which event the
Company shall issue the Warrantholder a number of shares of Common Stock
computed using the following formula:

                                 Y = X(A-B)/A

Where:
 
     X  =  the number of equal shares of Common Stock for which this Warrant is
           exercisable;
 
     Y  =  the number of shares of Common Stock to be issued to the Holder;
 
     A  =  the Fair Market Value (as defined below) of one share of the
           Company's Common Stock on the date of conversion of this Warrant; and
           
     B  =  the Exercise Price for one share of the Company's Common Stock under
           this Warrant.

                                      -2-
<PAGE>
 
     If the above calculation results in a negative number, then no shares of
Warrant Stock shall be issued or issuable upon conversion of this Warrant.

     "Fair Market Value" of a share of Common Stock shall mean:

     (a)  if this Warrant is exercised (i) immediately prior to a Qualified IPO,
          and (ii) if the Company's Registration Statement on Form S-1 or SB-2
          (or successor or equivalent forms) relating to such public offering
          has been declared effective by the Securities and Exchange Commission,
          then the Fair Market Value per share shall be the price per share to
          the public as specified in the final prospectus with respect to the
          offering;

     (b)  if this Warrant is exercised after the consummation of a Qualified
          IPO, then:

          (i)  if traded on a securities exchange, the Fair Market Value per
               share of Common Stock shall be deemed to be the average of the
               closing sales prices of the Company's Common Stock over a ten
               (10) day trading period (or for such shorter period as the
               Company's Common Stock may have been trading) ending three (3)
               days before the Exercise Date, or

          (ii) if traded over-the-counter, the Fair Market Value per share of
               Common Stock shall be deemed to be the average of the prices of
               the Company's Common Stock quoted on The Nasdaq Stock Market,
               Inc. (or NASD bulletin board or any similar system) over the ten
               (10) day trading period (or for such shorter period as the
               Company's Common Stock has been trading) ending three (3) days
               before the Exercise Date; or

     (c) if this Warrant is exercised prior to a Qualified IPO (except as
         provided in clause (a) above), the Fair Market Value per share of
         Common Stock shall be equal to an amount determined in good faith by
         the Company's Board of Directors, but shall in no event be less than
         the actual sale price per share in the Company's latest financing.

     Upon exercise of this Warrant in accordance with this Section 2, the holder
of this Warrant shall be entitled to receive from the Company a stock
certificate in proper form representing the number of shares of Warrant Stock so
purchased, and a new Warrant in substantially identical form and dated as of
such exercise for the purchase of that number of shares of Warrant Stock equal
to the difference, if any, between the number of shares of Warrant Stock subject
hereto and the number of shares of Warrant Stock as to which this Warrant is so
exercised.

     3.  CONVERSION OF WARRANT

     The Holder shall have the right to convert this Warrant, in whole or in
part, at any time (including, but not limited to, the occurrence of an
Acquisition of the Company) and from time to time at or prior to the Expiration
Time by the payment of the Exercise Price (as hereinafter defined), and
surrender of this Warrant and the Notice of Conversion form attached hereto duly
executed to the principal executive office of the Company at the address set
forth on the signature page hereof (or such other office or agency of the
Company as it may designate by notice in writing to the Holder at the address of
such Holder appearing on the books of the Company), into shares of Warrant Stock
as 

                                      -3-
<PAGE>
 
provided in this Section 3. Payment of the Exercise Price may be made by cash,
check or wire transfer or, at the election of the Warrantholder, may be made on
a "net exercise" basis, in which event the Company shall issue the Warrantholder
a number of shares of Common Stock computed using the formula set forth in
Section 2.

     Upon conversion of this Warrant in accordance with this Section 3, the
Holder hereof shall be entitled to receive a certificate for the number of
shares of Warrant Stock determined in accordance with the foregoing, and a new
Warrant in substantially identical form and dated as of such conversion for the
purchase of that number of shares of Warrant Stock equal to the difference, if
any, between the number of shares of Warrant Stock subject hereto and the number
of shares of Warrant Stock as to which this Warrant is so converted.

     4.  ISSUANCE OF SHARES; NO FRACTIONAL SHARES OR SCRIP

     Certificates for shares purchased hereunder or issuable upon conversion
hereof shall be delivered to the Holder promptly after the date on which this
Warrant shall have been exercised or converted in accordance with the terms
hereof.  The Company hereby represents and warrants that all shares of Warrant
Stock which may be issued upon the exercise or conversion of this Warrant will,
upon such exercise or conversion, be duly and validly authorized and issued,
fully paid and nonassessable and free from all liens and encumbrances in respect
of the issuance thereof (other than liens or encumbrances created by or imposed
upon the Holder of the Warrant Stock).  The Company agrees that the shares so
issued shall be and shall for all purposes be deemed to have been issued to such
Holder as the record owner of such shares as of the close of business on the
date on which this Warrant shall have been exercised or converted in accordance
with the terms hereof.  No fractional shares or scrip representing fractional
shares shall be issued upon the exercise or conversion of this Warrant.  With
respect to any fraction of a share called for upon the exercise or conversion of

     7.  COMPANY'S RIGHT OF FIRST REFUSAL PRIOR TO WARRANT EXERCISE

     Before the Warrant may be sold or otherwise transferred by the Holder or
any transferee (including transfer by gift or operation of law), the Company or

the terms and conditions set forth in this Section 7 (the "Right of First
Refusal").

          (a) Notice of Proposed Transfer.  The Holder shall deliver to the
              ---------------------------                                  
              Company a written notice (the "Notice") stating: (i) the Holder's
              bona fide intention to sell or otherwise transfer the Warrant;
              (ii) the name of the proposed purchaser or other transferee
              ("Proposed Transferee"); and (iii) the bona fide cash price or
              other consideration for which the Holder proposes to transfer the
              Warrant (the "Offered Price"), and the Holder shall offer the
              Warrant at the Offered Price to the Company or its assignee(s),
              provided that any such assignee is a securityholder of the
              Company.

          (b) Exercise of Right of First Refusal.  At any time within 20 days
              ----------------------------------                             
              after receipt of the Notice, the Company or its assignee(s) may,
              by giving written notice to the Holder, elect to purchase the
              Warrant proposed to be transferred to the Proposed Transferee, at
              the purchase price determined in accordance with subsection (c)
              below.

          (c) Purchase Price.  The purchase price ("Purchase Price") for the
              --------------                                                
              Warrant purchased by the Company or its assignee(s) under this
              Section shall be the Offered Price. If the Offered Price includes
              consideration other than cash, the cash equivalent value of the
              non-cash consideration shall be determined in good faith by the
              Board of Directors of the Company.

          (d) Payment.  Payment of the Purchase Price shall be made in cash (by
              -------                                                          
              check) within 15 days of the Company's written notice to the
              Holder pursuant to Section 7(b).

          (e) Holder's Right to Transfer.  If the Warrant proposed in the Notice
              --------------------------                                        
              to be transferred to a given Proposed Transferee is not purchased
              by the Company or its assignee(s) as provided in this Section,
              then the Holder may sell or otherwise transfer such Warrant to
              that Proposed Transferee at the Offered Price or at a higher
              price, provided that such sale or other transfer is consummated
              within 90 days after the date of the Notice and provided further
              that any such sale or other transfer is effected in accordance
              with any applicable securities laws and the Proposed Transferee
              agrees in writing that the provisions of this Section 7 shall
              continue to apply to the Warrant in the hands of such Proposed
              Transferee. If the Warrant described in the Notice is not
              transferred to the Proposed Transferee 

                                      -5-
<PAGE>
 
              within such period, a new Notice shall be given to the Company,
              and the Company or its assignees shall again be offered the Right
              of First Refusal before the Warrant held by the Holder may be sold
              or otherwise transferred.

          (f) Exception for Certain Transfers.  The Warrant may be transferred
              -------------------------------                                 
              without the Company being offered the Right of First Refusal in
              the following transactions; provided that any Transferee shall
              agree to the terms of this Section 7 as to the Warrant:

               (1) A Holder's transfer of the Warrant in whole or in part to the
                   Company or to any shareholder of the Company.

               (2) A Holder's transfer of the Warrant in whole or in part to a
                   person who, at the time of such transfer, is an officer or

               (3) A Holder's transfer of the Warrant in whole or in part
                   pursuant to and in accordance with the terms of any merger,
                   consolidation, reclassification of shares or capital
                   reorganization of the corporate shareholder, or pursuant to a
                   sale of all or substantially all of the stock or assets of a
                   corporate shareholder.

               (4) A transfer by a Holder which is a limited or general
                   partnership to any or all of its partners or former partners
                   or any professional employee (or entity of which such
                   employees are the beneficiaries) of such partnership.

               (5) A transfer by a Holder which is a corporation to any parent
                   company of the Holder, or any majority-owned subsidiary of
                   such parent company, provided that any such transferee does
                   not derive a majority of its revenues from products or
                   services that compete directly with products or services from
                   which the Company derives a majority of its revenues.

               (6) Any transfer by a Holder which is a limited liability company
                   to any or all of its members or former members or any
                   professional employee (or entity of which such employees are
                   the beneficiaries) of such limited liability company.

     Any such transfer shall be made upon surrender of this Warrant together
with the Assignment Form attached hereto properly endorsed.

          (g) Termination of Right of First Refusal.  The Right of First Refusal
              -------------------------------------                             
              shall terminate (i) as to any Warrant Stock acquired upon the
              exercise or conversion of the Warrant in whole or in part, on the
              effective date of such exercise or conversion and (ii) as to any
              portion of the Warrant not previously exercised or converted, on
              the date 180 days after the date of the final prospectus (the
              "Final Prospectus") 

                                      -6-

              contained in a registration statement filed with and declared
              effective by the Securities and Exchange Commission under the
              Securities Act relating to the initial public offering by the
              Company of its capital stock.

     8.   MARKET STAND-OFF AGREEMENT

     The Holder hereby agrees in connection with any registration of the
Company's securities (other than a registration of securities in a Rule 145
transaction or with respect to an employee benefit plan), upon request of the
Company or the underwriters managing any underwritten offering of the Company's
securities, not to sell, make any short sale of, loan, pledge (or otherwise
encumber or hypothecate), grant any option for the purchase of, or otherwise
directly or indirectly dispose of any shares or other securities of the Company
(other than those included in the registration) without the prior written
consent of the Company and such managing underwriters for such period of time,
not to exceed 180 days following the date of the Final Prospectus, as the Board
of Directors establishes pursuant to its good faith negotiations with such
managing underwriters; provided, however, that the Holder shall not be subject
to such market stand-off unless the officers and directors of the Company who
own stock of the Company shall also be bound by such restrictions. The Company
may impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such 180-day period.

     9.  EXCHANGE AND REGISTRY OF WARRANT

     This Warrant is exchangeable, upon the surrender hereof by the Holder at
the above-mentioned office or agency of the Company, for a new Warrant in
substantially identical form and dated as of such exchange.  The Company shall
maintain at the above-mentioned office or agency a registry showing the name and
address of the registered Holder of this Warrant.  This Warrant may be
surrendered for exchange, transfer, exercise or conversion, in accordance with
its terms, at such office or agency of the Company, and the Company shall be
entitled to rely in all respects, prior to written notice to the contrary, upon
such registry.

     10.  LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT

     On receipt by the Company of evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant, and in
case of any such loss, theft or destruction of this Warrant, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of any such mutilation, on surrender and cancellation of such
Warrant, the Company will execute and deliver to the Holder, in lieu thereof, a
new warrant in substantially identical form, dated as of such cancellation and
reissuance.

     11.  SATURDAYS, SUNDAYS AND HOLIDAYS

     If the last or appointed day for the taking of any action or the expiration
of any right required or granted herein shall be a Saturday or a Sunday or shall
be a legal holiday, then such action may be taken or such right may be exercised

     12.  ADJUSTMENTS

     The type and number of securities of the Company issuable upon exercise of
this Warrant and the Exercise Price are subject to adjustment as set forth
below:

          (a) If the Company shall at any time declare a dividend payable in
              shares of Common Stock, then the Warrantholder, upon exercise of
              this Warrant after the record date for the determination of
              holders of Common Stock entitled to receive such dividend, shall
              be entitled to receive upon exercise of this Warrant, in addition
              to the number of shares of Common Stock as to which this Warrant
              is exercised, such additional shares of Common Stock as such
              holder would have received had this Warrant been exercised
              immediately prior to such record date.

          (b) If the Company shall at any time effect a recapitalization or
              reclassification of such character that the shares of Common Stock
              shall be changed into or become exchangeable for a larger or
              smaller number of shares, then upon the effective date thereof the
              number of shares of Common Stock which the Warrantholder shall be
              entitled to purchase upon exercise of this Warrant shall be
              increased or decreased, as the case may be, in direct proportion
              to the increase or decrease in the number of shares of Common
              Stock by reason of such recapitalization or reclassification, and
              the Exercise Price shall be, in the case of an increase in the
              number of shares, proportionately decreased and, in the case of a
              decrease in the number of shares, proportionately increased.

          (c) If the Company shall at any time distribute to holders of Common
              Stock cash, evidences of indebtedness or other securities or
              assets (other than cash dividends or distributions payable out of
              earned surplus) then, in any such case, the Warrantholder shall be
              entitled to receive, upon exercise of this Warrant, with respect
              to each share of Common Stock issuable upon such exercise, the
              amount of cash or evidences of indebtedness or other securities or
              assets which such holder would have been entitled to receive with
              respect to each such share of Common Stock as a result of the
              happening of such event had this Warrant been exercised
              immediately prior to the record date or other date fixing
              stockholders to be affected by such event.

          (d) If at any time on or after the date hereof the Company shall
              subdivide its outstanding shares of Common Stock into a greater
              number of shares, the Warrant Price in effect immediately prior to
              such subdivision shall thereby be proportionately reduced and the
              number of shares receivable upon exercise of the Warrant shall
              thereby be proportionately increased; and, conversely, if at any
              time on or after the date hereof the outstanding number of shares
              of Common Stock shall be combined into a smaller number of shares,
              the Warrant Price in effect immediately prior to such combination
              shall thereby be proportionately increased 

                                      -8-
<PAGE>
 
              and the number of shares receivable upon exercise of the Warrant
              shall thereby be proportionately decreased.

          (e) As used in this Warrant the term "Exercise Price" shall mean the
              purchase price per share specified in this Warrant until the
              occurrence of an event stated in subsections (b) or (d) of this
              Section 12 and thereafter shall mean said price as adjusted from
              time to time in accordance with the provisions of said
              subsections. No adjustment made pursuant to any provision of this
              Section 12 shall have the effect of increasing the total
              consideration payable upon exercise of this Warrant in respect of
              all the Common Stock as to which this Warrant may be exercised.

          (f) In the event that at any time, as a result of an adjustment made
              pursuant to this Section 12, the Warrantholder shall, upon
              exercise of this Warrant, become entitled to receive shares and/or
              other securities or assets (other than Common Stock) then,
              wherever appropriate, all references herein to shares of Common
              Stock shall be deemed to refer to and include such shares and/or
              other securities or assets; and thereafter the number of such
              shares and/or other securities or assets shall be subject to
              adjustment from time to time in a manner and upon terms as nearly
              equivalent as practicable to the provisions of this Section 12.

          (g) In case of any adjustment in the Exercise Price or number and type
              of securities issuable on the exercise of this Warrant, the
              Company will promptly give written notice thereof to the Holder in
              the form of a certificate, confirmed by an officer of the Company,
              setting forth such adjustment and showing in reasonable detail the
              facts upon which adjustment is based.

     13.  NOTICES OF RECORD DATE, ETC.

     In the event of:

          (a) any taking by the Company of a record of the holders of Warrant
              Stock or securities into which the Warrant Stock is convertible
              for the purpose of determining the holders thereof who are
              entitled to receive any dividend or other distribution,

          (b) any capital reorganization of the Company, any reclassification or
              recapitalization of the capital stock of the Company, or any
              transfer of all or substantially all the assets of the Company to,
              or consolidation or merger of, the Company with or into any
              person,

          (c) any voluntary or involuntary dissolution, liquidation or winding-
              up of the Company,

                                      -9-
<PAGE>
 
          (d) a sale of substantially all of the outstanding capital stock of
              the Company or the issuance of new shares representing the
              majority of the Company's right to vote, or

          (e) the consummation of any Qualified IPO of the Company's Common
              Stock,

then and in each such event the Company will mail to the Holder a notice
specifying the record date for voting or the date of closing , as applicable, of
any event (a)-(e) above.  Such notice shall be delivered to the Holder at least
fifteen (15) days prior to the actual or proposed date of consummation of the
relevant event.

     THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OR CONVERSION HEREOF
     HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     ANY APPLICABLE STATE LAWS, AND NO INTEREST THEREIN MAY BE SOLD,

NO.  1                       POINTCAST INCORPORATED          DECEMBER 10, 1996
    ---                                                      -----------


                   SERIES D PREFERRED STOCK PURCHASE WARRANT


     This certifies that, for value received, Cable News Network, Inc. (together
with any registered assignee(s), the "Holder") is entitled, upon the terms and
subject to the conditions hereinafter set forth, at any time on or after the
date hereof and at or prior to 11:59 p.m. on the Expiration Date (as defined
below), but not thereafter, to acquire from PointCast Incorporated, a California
corporation (the "Company"), in whole or from time to time in part, and in
accordance with the provisions of Section 1 below, up to 526,316 fully paid and
nonassessable shares of Series D Preferred Stock of the Company ("Warrant
Stock") at a purchase price equal to $9.50 per share (the "Exercise Price").
Such number of shares, type of security and Exercise Price are subject to
adjustment as provided herein, and all references to "Warrant Stock" and
"Exercise Price" herein shall be deemed to include any such adjustment or series
of adjustments.

     1.   TERM

          (a) Termination and Expiration.  If not earlier exercised, the Warrant
              --------------------------                                        
shall expire on the date (the "Expiration Date") that is the earlier of (i) 18
months after the effective date of an initial public offering by the Company of
its capital stock with aggregate gross proceeds to the Company of not less than
$20,000,000 and with a price per share of not less than $9.50 (a "Qualified
IPO") and (ii) 36 months after the date first set forth above.

          (b) Exceptions.  Notwithstanding the foregoing, the Warrant shall
              ----------                                                   
terminate, if not earlier exercised, in the event of an acquisition of the
Company.  In the event the Company is proposed to be acquired in a bona fide
transaction (the "Acquisition") (i.e., not a mere recapitalization,
reincorporation for the purpose of changing corporate domicile, or similar
transaction), regardless of the form of the transaction (e.g., merger,
consolidation, sale or lease of assets or sale of stock), the Company shall give
the Holder not less than (i) fifteen (15) business days' notice of the record
date for determining the shareholders of the Company entitled to vote on (or
otherwise approve) the 
<PAGE>
 
Acquisition or (ii) 60 calendar days' notice of the effective date of the
Acquisition, whichever is longer; the Company shall provide the Holder with all
information with respect to the Acquisition that is otherwise provided to
shareholders of the Company at such time and from time to time during the
pendency of the Acquisition, including (but not limited to) the proposed price
to be paid in the proposed Acquisition; the Holder shall have the right to
exercise same on or prior to the record date of shareholders eligible to vote
(or otherwise approve) with respect to the proposed Acquisition; if the Warrant
is not exercised on or prior to such record date, the Warrant shall expire upon
the occurrence of the closing of the Acquisition.

     2.  EXERCISE OF WARRANT

     The purchase rights represented by this Warrant are exercisable by the
registered holder hereof, in whole or in part, at any time and from time to time
at or prior to the Expiration Time by the surrender of this Warrant and the
Notice of Exercise form attached hereto duly executed to the headquarters office
of the Company at the address set forth on the signature page hereof (or such
other office or agency of the Company as it may designate by notice in writing
to the registered holder hereof at the address of such holder appearing on the
books of the Company), and upon payment of the Exercise Price for the shares
thereby purchased (by cash or by check or bank draft payable to the order of the
Company or by cancellation of indebtedness of the Company to the holder hereof,
if any, at the time of exercise in an amount equal to the purchase price of the
shares thereby purchased); whereupon the holder of this Warrant shall be
entitled to receive from the Company a stock certificate in proper form
representing the number of shares of Warrant Stock so purchased, and a new
Warrant in substantially identical form and dated as of such exercise for the
purchase of that number of shares of Warrant Stock equal to the difference, if
any, between the number of shares of Warrant Stock subject hereto and the number
of shares of Warrant Stock as to which this Warrant is so exercised.

     3.  CONVERSION OF WARRANT

     The Holder shall have the right to convert this Warrant, in whole or in
part, at any time (including, but not limited to, the occurrence of an
Acquisition of the Company) and from time to time at or prior to the Expiration
Time by the surrender of this Warrant and the Notice of Conversion form attached
hereto duly executed to the headquarters office of the Company at the address
set forth on the signature page hereof (or such other office or agency of the
Company as it may designate by notice in writing to the Holder at the address of
such Holder appearing on the books of the Company), into shares of Warrant Stock
as provided in this Section 3.  Upon exercise of this conversion right, the
Holder shall be entitled to receive that number of shares of the Company's


Preferred Stock computed by using the following formula:

                                      X(A-B)
                                 y = --------
                                        A

                                      -2-
<PAGE>
 
     Y  =  the number of shares of Series D Preferred Stock to be issued to the
           Holder.
 
     A  =  the Fair Market Value (as defined below) of one share of the
           Company's Series D Preferred Stock on the date of conversion of this
           Warrant. 
 
     B  =  the Exercise Price for one share of the Company's Series D Preferred
           Stock under this Warrant.
 
     X  =  the number of shares of Series D Preferred Stock purchasable under
           this Warrant.

     If the above calculation results in a negative number, then no shares of
Warrant Stock shall be issued or issuable upon conversion of this Warrant.

     "Fair Market Value" of a share of Series D Preferred Stock shall mean:

           (a) if the conversion right is being exercised in connection with the
               initial public offering (the "IPO") of the Company's Common Stock
               (the "Common Stock"), the IPO price per share (before deducting
               commissions, discounts or expenses) at which the Common Stock is
               sold to the public in the IPO, multiplied by the number of shares
               of Common Stock into which a share of Series D Preferred Stock is
               convertible at the time of the exercise of the conversion right
               (the "Conversion Rate").

           (b) if the conversion right is being exercised in connection with an
               Acquisition, the price per share to be paid to holders of the
               Company's Series D Preferred Stock by the acquiring entity; or,
               if no such price per share has been established, the price per
               share to be paid to the holders of the Company's Common Stock
               multiplied by the Conversion Rate.

           (c) if the conversion right is being exercised after the IPO (other
               than in connection with an Acquisition) the average of the
               closing prices for the Company's Common Stock for the ten (10)
               trading days prior to the date the Company receives the Warrant
               and duly executed Notice of Conversion, multiplied by the
               Conversion Rate.

           (d) in all other cases, the fair value as determined in good faith by
               the Company's Board of Directors.

     Upon conversion of this Warrant in accordance with this Section 3, the
Holder hereof shall be entitled to receive a certificate for the number of
shares of Warrant Stock determined in accordance 

                                      -3-
<PAGE>
 
with the foregoing, and a new Warrant in substantially identical form and dated
as of such conversion for the purchase of that number of shares of Warrant Stock
equal to the difference, if any, between the number of shares of Warrant Stock
subject hereto and the number of shares of Warrant Stock as to which this
Warrant is so converted.

     4.  ISSUANCE OF SHARES; NO FRACTIONAL SHARES OR SCRIP

     Certificates for shares purchased hereunder or issuable upon conversion
hereof shall be delivered to the Holder within a reasonable time after the date
on which this Warrant shall have been exercised or converted in accordance with
the terms hereof.  The Company hereby represents and warrants that all shares of
Warrant Stock which may be issued upon the exercise or conversion of this
Warrant will, upon such exercise or conversion, be duly and validly authorized
and issued, fully paid and nonassessable and free from all taxes, liens and
charges in respect of the issuance thereof (other than liens or charges created
by or imposed upon the holder of the Warrant Stock).  The Company agrees that
the shares so issued shall be and shall for all purposes be deemed to have been
issued to such holder as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been exercised or
converted in accordance with the terms hereof.  No fractional shares or scrip
representing fractional shares shall be issued upon the exercise or conversion
of this Warrant.  With respect to any fraction of a share called for upon the
exercise or conversion of this Warrant, an amount equal to such fraction
multiplied by the Fair Market Value of a share of Warrant Stock on the date of
exercise or conversion shall be paid in cash or check to the Holder.

     5.  CHARGES, TAXES AND EXPENSES

     Issuance of certificates for shares of Warrant Stock upon the exercise or
conversion of this Warrant shall be made without charge to the Holder for any
issue or transfer tax or other incidental expense in respect of the issuance of
such certificate, all of which taxes and expenses shall be paid by the Company,
and such certificates shall be issued in the name of the Holder or in such name
or names as may be directed by the Holder provided, however, that in the event
certificates for shares of Warrant Stock are to be issued in a name other than
the name of the Holder, this Warrant when surrendered for exercise or conversion
shall be accompanied by the Assignment Form attached hereto duly executed by the
Holder.

     6.  RIGHTS AS SHAREHOLDERS

     The Holder shall not, solely as such, be entitled to vote upon any matter
submitted to shareholders at any meeting thereof, or to receive notice of
meetings, or to be deemed the holder of Series D Preferred Stock until this
Warrant shall have been exercised or converted in whole or in part and the
Warrant Stock purchasable upon such exercise shall have become deliverable, as
provided herein.  Thereafter, upon the Holder's signing of the Investor Rights
Agreement (as hereinafter defined), the Holder shall have the rights and
responsibilities of an Investor under the Amended and Restated Investor Rights
Agreement (the "Investor Rights Agreement"), dated as of July 19, 1996, by 

                                      -4-
<PAGE>
 
and among the Company, the persons set forth on the Schedule of Investors
attached thereto as Exhibit A, Lighthouse Capital Partners, L.P. and certain
officers of the Company, with each share of Warrant Stock being deemed
equivalent to one share of Registrable Securities or Shares, as the case may be,
under such Investor Rights Agreement.

     7.   COMPANY'S RIGHT OF FIRST REFUSAL

     Before any Warrants, or if exercised, any shares of Series D Preferred
Stock or Common Stock (the "Converted Shares") held by the Holder or any
transferee may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

          (a) Notice of Proposed Transfer.  The Holder shall deliver to the
              ---------------------------                                  
Company a written notice (the "Notice") stating: (i) the Holder's bona fide
intention to sell or otherwise transfer such Warrants or Converted Shares, as
the case may be; (ii) the name of each proposed purchaser or other transferee
("Proposed Transferee"); (iii) the number of Warrants or Converted Shares to be
transferred to each Proposed Transferee; and (iv) the bona fide cash price or
other consideration for which the Holder proposes to transfer the Warrants or
the Converted Shares (the "Offered Price"), and the Holder shall offer the
Warrants or the Converted Shares at the Offered Price to the Company or its
assignee(s).

          (b) Exercise of Right of First Refusal.  At any time within 30 days
              ----------------------------------                             
after receipt of the Notice, the Company or its assignee(s) may, by giving
written notice to the Holder, elect to purchase all, but not less than all, of
the Warrants or Converted Shares proposed to be transferred to any one or more
of the Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

          (c) Purchase Price.  The purchase price ("Purchase Price") for the
              --------------                                                
Warrants or Converted Shares purchased by the Company or its assignee(s) under
this Section shall be the Offered Price.  If the Offered Price includes
consideration other than cash, the cash equivalent value of the non-cash
consideration shall be determined by the Board of Directors of the Company in
good faith.

          (d) Payment.  Payment of the Purchase Price shall be made in cash (by
              -------                                                          
check) within 45 days of receipt of the Notice.

          (e) Holder's Right to Transfer.  If all of the Warrants or Converted
              --------------------------                                      
Shares proposed in the Notice to be transferred to a given Proposed Transferee
are not purchased by the Company or its assignee(s) as provided in this Section,
then the Holder may sell or otherwise transfer such Warrants or Converted Shares
to that Proposed Transferee at the Offered Price or at a higher price, provided
that such sale or other transfer is consummated within 120 days after the date
of the Notice and provided further that any such sale or other transfer is
effected in accordance with 

                                      -5-
<PAGE>
 
any applicable securities laws and the Proposed Transferee agrees in writing
that the provisions of this Section shall continue to apply to the Warrants or
Converted Shares in the hands of such Proposed Transferee. If the Warrants or
Converted Shares described in the Notice are not transferred to the Proposed
Transferee within such period, a new Notice shall be given to the Company, and
the Company or its assignees shall again be offered the Right of First Refusal
before any Warrants or Converted Shares held by the Holder may be sold or
otherwise transferred.

          (f) Exception for Certain Transfers.  The Warrant or Converted Shares
              -------------------------------                                  
may be transferred without the Company being offered the Right of First Refusal
in the following transactions; provided that any Transferee shall agree to the
terms of this Section 7 as to the Warrant or any Converted Shares:

                    (1) A Holder's transfer of the Warrant or Converted Shares
in whole or in part to the Company or to any shareholder of the Company.

                    (2) A Holder's transfer of the Warrant or Converted Shares
in whole or in part to a person who, at the time of such transfer, is an officer
or director of the Company.

                    (3) A Holder's transfer of the Warrant or Converted Shares
in whole or in part pursuant to and in accordance with the terms of any merger,
consolidation, reclassification of shares or capital reorganization of the
corporate shareholder, or pursuant to a sale of all or substantially all of the
stock or assets of a corporate shareholder.

                    (4) A transfer by a Holder which is a limited or general
partnership to any or all of its partners or former partners or any professional
employee (or entity of which such employees are the beneficiaries) of such
partnership.

                    (5) A transfer by a Holder to any entity who (i) at the date
hereof or at the date of the proposed transfer is, or has the power to become
through the exercise or conversion of securities, an affiliate, as such term is
defined in Rule 405 under the Securities Act of 1933, as amended (the
"Securities Act"), of a Holder, and (ii) does not derive a substantial portion
of its revenues from products or services that compete with products or services
from which the Company derives a substantial portion of its revenues.

     Any such transfer shall be made upon surrender of this Warrant or Converted
Shares together with the Assignment Form attached hereto properly endorsed.

          (g) Termination of Right of First Refusal.  The Right of First Refusal
              -------------------------------------                             
shall terminate as to any Shares 90 days after the first sale of Common Stock of
the Company to the general public pursuant to a registration statement filed
with and declared effective by the Securities and Exchange Commission under the
Securities Act.

                                      -6-
<PAGE>
 
     8.   MARKET STAND-OFF AGREEMENT

     The Holder hereby agrees that if so requested by the Company or any
representative of the underwriters in connection with any registration of the
offering of any shares of the Company under the Securities Act, the Holder shall
not sell or otherwise transfer any shares or other securities of the Company
during the 180-day period following the date of the final Prospectus contained
in a registration statement of the Company filed under the Securities Act;
provided, however, that such restriction shall only apply to the first
registration statement of the Company to become effective under the Securities
Act which includes securities to be sold on behalf of the Company to the public
in an underwritten public offering under the Securities Act.  The Company may
impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such 180-day period.

     9.   EXCHANGE AND REGISTRY OF WARRANT

     This Warrant is exchangeable, upon the surrender hereof by the Holder at
the above-mentioned office or agency of the Company, for a new Warrant in
substantially identical form and dated as of such exchange.  The Company shall
maintain at the above-mentioned office or agency a registry showing the name and
address of the registered holder of this Warrant.  This Warrant may be
surrendered for exchange, transfer, exercise or conversion, in accordance with
its terms, at such office or agency of the Company, and the Company shall be
entitled to rely in all respects, prior to written notice to the contrary, upon
such registry.

     10.  LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT

     On receipt by the Company of evidence reasonably satisfactory to the

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

                   SERIES D PREFERRED STOCK PURCHASE WARRANT


     This certifies that, for value received, Time Inc. New Media (together with
any registered assignee(s), the "Holder") is entitled, upon the terms and
subject to the conditions hereinafter set forth, at any time on or after the
date hereof and at or prior to 11:59 p.m. on the Expiration Date (as defined
below), but not thereafter, to acquire from PointCast Incorporated, a California
corporation (the "Company"), in whole or from time to time in part, up to
526,316 fully paid and nonassessable shares of Series D Preferred Stock of the
Company ("Warrant Stock") at a purchase price equal to $9.50 per share (the
"Exercise Price").  Such number of shares, type of security and Exercise Price
are subject to adjustment as provided herein, and all references to "Warrant
Stock" and "Exercise Price" herein shall be deemed to include any such
adjustment or series of adjustments.

     1.   TERM

          1.1  Termination and Expiration.  If not earlier exercised, the
               --------------------------                                
Warrant shall expire on the date (the "Expiration Date") that is the earlier of
(i) eighteen (18) months after the effective date of the registration statement
for an initial public offering by the Company of its capital stock with
aggregate gross proceeds to the Company of not less than $20,000,000 and with a
price per share of not less than $9.50 (a "Qualified IPO") and (ii) 60 months
after the date first set forth above.

          1.2  Exceptions.  Notwithstanding the foregoing, in the event the
               ----------                                                  
Company is proposed to be acquired in a bona fide transaction (i.e., not a mere
recapitalization, reincorporation for the purpose of changing corporate
domicile, or similar transaction) (the "Acquisition"), regardless of the form of
the transaction (e.g., merger, consolidation, sale or lease of assets or sale of
stock), the Company shall give the Holder not less than fifteen (15) business
days notice of the record date for determining the shareholders of the Company
entitled to vote on (or otherwise approve) the Acquisition; the Company shall
provide the Holder with all information with respect to the Acquisition that is
otherwise provided to shareholders of the Company at such time and from time to
time during the pendency of the Acquisition, including (but not limited to) the
proposed price to be paid in the proposed Acquisition; the Holder shall have the
right to exercise same on or prior to the record date of shareholders eligible
to vote (or otherwise approve) with respect to the proposed Acquisition; if the
Warrant is not exercised on or prior to such record date, the Warrant shall
expire upon the occurrence of the closing of the Acquisition.
<PAGE>
 
     2.  EXERCISE OF WARRANT

     The purchase rights represented by this Warrant are exercisable by the
registered holder hereof, in whole or in part, at any time and from time to time
at or prior to the Expiration Time by the surrender of this Warrant and the
Notice of Exercise form attached hereto duly executed to the headquarters office
of the Company at the address set forth on the signature page hereof (or such
other office or agency of the Company as it may designate by notice in writing
to the registered holder hereof at the address of such holder appearing on the
books of the Company), and upon payment of the Exercise Price for the shares
thereby purchased (by cash or by check or bank draft payable to the order of the
Company or by cancellation of indebtedness of the Company to the holder hereof,
if any, at the time of exercise in an amount equal to the purchase price of the
shares thereby purchased); whereupon the holder of this Warrant shall be
entitled to receive from the Company a stock certificate in proper form
representing the number of shares of Warrant Stock so purchased, and a new
Warrant in substantially identical form and dated as of such exercise for the
purchase of that number of shares of Warrant Stock equal to the difference, if
any, between the number of shares of Warrant Stock subject hereto and the number
of shares of Warrant Stock as to which this Warrant is so exercised.

     3.  CONVERSION OF WARRANT

     The Holder shall have the right to convert this Warrant, in whole or in
part, at any time (including, but not limited to, the occurrence of an
Acquisition of the Company) and from time to time at or prior to the Expiration
Time by the surrender of this Warrant and the Notice of Conversion form attached
hereto duly executed to the headquarters office of the Company at the address
set forth on the signature page hereof (or such other office or agency of the
Company as it may designate by notice in writing to the Holder at the address of
such Holder appearing on the books of the Company), into shares of Warrant Stock
as provided in this Section 3.  Upon exercise of this conversion right, the
Holder shall be entitled to receive that number of shares of the Company's
Preferred Stock computed by using the following formula:

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

        Y      =    the number of shares of Series D Preferred Stock to be
                    issued to the Holder.
 
        A      =    the Fair Market Value (as defined below) of one share of the
                    Company's Series D Preferred Stock on the date of conversion
                    of this Warrant.

        B      =    the Exercise Price for one share of the Company's Series D
                    Preferred Stock under this Warrant.
 
        X      =    the number of shares of Series D Preferred Stock that the
                    Holder desires to purchase pursuant to complete or partial
                    conversion of the Warrant. 

     If the above calculation results in a negative number, then no shares of
Warrant Stock shall be issued or issuable upon conversion of this Warrant.

     "Fair Market Value" of a share of Series D Preferred Stock shall mean:

               (a) if the conversion right is being exercised in connection with
                   the initial public offering (the "IPO") of the Company's
                   Common Stock (the "Common Stock"),

                                      -2-
<PAGE>
 
                   the IPO price per share (before deducting commissions,
                   discounts or expenses) at which the Common Stock is sold to
                   the public in the IPO, multiplied by the number of shares of
                   Common Stock into which a share of Series D Preferred Stock
                   is convertible at the time of the exercise of the conversion
                   right (the "Conversion Rate").

               (b) if the conversion right is being exercised in connection with
                   an Acquisition, the price per share to be paid to the holders
                   of the Company's Series D Preferred Stock by the acquiring
                   entity, or, if no such price per share has been established,
                   the price per share to be paid to the holders of the
                   Company's Common Stock multiplied by the Conversion Rate.

               (c) if the conversion right is being exercised after the IPO
                   (other than in connection with an Acquisition), then (i) if
                   the Company's Common Stock is listed on a national securities
                   exchange, the average of last sale prices for the Company's
                   Common Stock for the fifteen (15) trading days prior to the
                   date the Company receives the Warrant and duly executed
                   Notice of Conversion (the "Notice Receipt Date"), multiplied
                   by the Conversion Rate, or (ii) if the Company's Common Stock
                   is listed on The Nasdaq Stock Market, the average of the
                   average bid and ask price for each of the fifteen (15)
                   trading days prior to the Notice Receipt Date, multiplied by
                   the Conversion Rate.

               (d) in all other cases, the fair value as determined in good
                   faith by the Company's Board of Directors.

     Upon conversion of this Warrant in accordance with this Section 3, the
Holder hereof shall be entitled to receive a certificate for the number of
shares of Warrant Stock determined in accordance with the foregoing, and a new
Warrant in substantially identical form and dated as of such conversion for the
purchase of that number of shares of Warrant Stock equal to the difference, if
any, between the number of shares of Warrant Stock subject hereto and the number
of shares of Warrant Stock as to which this Warrant is so converted.

     4.  ISSUANCE OF SHARES; NO FRACTIONAL SHARES OR SCRIP

     Certificates for shares purchased hereunder or issuable upon conversion
hereof shall be delivered to the Holder promptly after the date on which this
Warrant shall have been exercised or converted in accordance with the terms
hereof.  The Company hereby represents and warrants that all shares of Warrant
Stock which may be issued upon the exercise or conversion of this Warrant will,
upon such exercise or conversion, be duly and validly authorized and issued,
fully paid and nonassessable and free from all taxes, liens and charges in
respect of the issuance thereof (other than liens or charges created by or
imposed upon the holder of the Warrant Stock).  The Company agrees that the
shares so issued shall be and shall for all purposes be deemed to have been
issued to such holder as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been exercised or
converted in accordance with the terms hereof.  No fractional shares or scrip
representing fractional shares shall be issued upon the exercise or conversion
of this Warrant. With respect to any fraction of a share called for upon the
exercise or conversion of this Warrant, an amount equal to such fraction
multiplied by the Fair Market Value of a share of Warrant Stock on the date of
exercise or conversion shall be paid in cash or check to the Holder.

                                      -3-
<PAGE>
 
     5.  CHARGES, TAXES AND EXPENSES

     Issuance of certificates for shares of Warrant Stock upon the exercise or
conversion of this Warrant shall be made without charge to the Holder for any
issue or transfer tax or other incidental expense in respect of the issuance of
such certificate, all of which taxes and expenses shall be paid by the Company,
and such certificates shall be issued in the name of the Holder or in such name
or names as may be directed by the Holder provided, however, that in the event
certificates for shares of Warrant Stock are to be issued in a name other than
the name of the Holder, this Warrant when surrendered for exercise or conversion
shall be accompanied by the Assignment Form attached hereto duly executed by the
Holder.

     6.   RIGHTS AS SHAREHOLDERS

     No holder of this Warrant, as such, shall be entitled to vote upon any
matter submitted to shareholders at any meeting thereof, or to receive notice of
meetings, or be deemed the holder of Series D Preferred Stock until this Warrant
shall have been exercised or converted in whole or in part and the Warrant Stock
purchasable upon such exercise shall have become deliverable, as provided
herein.  Thereafter, the Holder thereof shall have the rights and
responsibilities of:  (i) an Investor under the Amended and Restated Investor
Rights Agreement (the "Investor Rights Agreement"), dated as of July 19, 1996,
by and among the Company, the persons set forth on the Schedule of Investors
attached thereto as Exhibit A, Lighthouse Capital Partners, L.P. and certain
officers of the Company, with each share of Warrant Stock being deemed
equivalent to one share of Registrable Securities or Shares, as the case may be,
under such Investor Rights Agreement; and (ii) a Series D Purchaser under each
of (A) the Amended and Restated Investors' Co-Sale Agreement, dated as of July
19, 1996, by and among the Company, the purchasers of the Company's Series D
Preferred Stock, the holders of the Company's other series of Preferred Stock,
and certain officers of the Company and (B) the Amended and Restated Co-Sale
Agreement of even date therewith by and among the same parties (such agreements
being referred to collectively as the "Co-Sale Agreements"), with each share of
Warrant Stock being deemed equivalent to one share of Co-Sale Securities under
such Co-Sale Agreements; in each case of (i) and (ii), as if such Holder were a
signatory to each such agreement.

     7.  COMPANY'S RIGHT OF FIRST REFUSAL PRIOR TO WARRANT EXERCISE

     Before the Warrant may be sold or otherwise transferred by the Holder or
any transferee (including transfer by gift or operation of law), the Company or
its assignee(s) shall have a right of first refusal to purchase the Warrant on
the terms and conditions set forth in this Section (the "Right of First
Refusal").

          (a) Notice of Proposed Transfer.  The Holder shall deliver to the
              ---------------------------                                  
Company a written notice (the "Notice") stating: (i) the Holder's bona fide
intention to sell or otherwise transfer the Warrant; (ii) the name of the
proposed purchaser or other transferee ("Proposed Transferee"); and (iii) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Warrant (the "Offered Price"), and the Holder shall offer the
Warrant at the Offered Price to the Company or its assignee(s), provided that
any such assignee is a securityholder of the Company.

          (b) Exercise of Right of First Refusal.  At any time within 20 days
              ----------------------------------                             
after receipt of the Notice, the Company or its assignee(s) may, by giving
written notice to the Holder, elect to purchase the Warrant proposed to be

                           LOAN & SECURITY AGREEMENT



THIS LOAN AND SECURITY AGREEMENT entered into as of the 18th day of November,
1997 by and between MetLife Capital Corporation, a Delaware corporation, whose
address is 10900 NE 4th Street, Suite 500, Bellevue, WA 98004 ("Lender") and
PointCast Incorporated, a California corporation, whose address is 501 Marcara
Avenue, Sunnyvale, CA 94086 ("Borrower").

     WHEREAS, Lender has agreed to make a commercial loan or loans to Borrower:
and

     WHEREAS, as a condition to making the loans, and in order to secure the
repayment thereof, Lender has required Borrower to execute and deliver to Lender
this Loan and Security Agreement.

     NOW THEREFORE, for good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, Borrower and Lender agree as follows:

1.   CREATION OF SECURITY INTEREST.  As security for the due and punctual
     -----------------------------
payment of any and all of the present and future obligations of the borrower to
Lender under this Loan and Security Agreement and the other Loan Documents (as
defined below), whether direct or contingent or joint or several, Borrower
hereby conveys, assigns and grants to Lender a continuing security interest in
all of Borrower's rights, title and interests in and to the equipment described
in the Supplemental Security Agreement(s) entered into pursuant to this Loan and
Security Agreement from time to time ("Equipment") including all present and
future additions, attachments and accessories thereto, all substitutions
therefor and replacements thereof and all proceeds thereof, including all
proceeds of insurance (such Equipment and property hereinafter called
"Collateral").

2.   THE LOANS.
     ---------

(a)  Subject to the terms and conditions of this Loan and Security Agreement,
lender agrees to make a loan or loans to Borrower. The maximum principal amount
of any loan or loans to be made by Lender to Borrower shall be within Lender's
discretion, subject to the exercise of Lender's reasonable business judgment,
and shall be as stated in the loan commitment letter issued by lender to
Borrower, or in the event a commitment letter is not issued by Lender, in
Lender's internal credit approval (each such loan or loans shall be referred to
as "the Loan Amount").

(b)  The Loan Amounts shall be repaid by Borrower as a term loan or term loans
("Term Loan"). The Term Loan shall be evidenced by a promissory note or notes in
the form attached hereto as Exhibit "A" ("Term Note"). The payment provisions of
each Term Note shall be stated therein.

(c)  If requested by Borrower, and in accordance with the terms and conditions
of Section 3 hereof, Lender shall make interim fundings to Borrower of a Term
Loan as partial advances of the Loan Amount ("Interim Loans"). The interim Loans
shall either be for the payment of the acquisition cost of any items of
Equipment delivered and accepted by Borrower prior to the expiration date of
Lender's loan commitment to Borrower ("Commitment Expiration date") or to fund
progress payments to the vendor or manufacturer of the Equipment, if the making
of progress payments was agreed to by Lender in its commitment or approval to
make the loan or loans to Borrower. The Interim Loans shall be evidenced by
promissory notes in the form attached hereto as Exhibit "B" ("interim Note").
Interest on all Interim Loans shall be payable as provided therein. The
principal amount due under the Interim Loans shall be due as provided in the
Interim Notes, at which time, provided no Event of Default hereunder has
occurred and is continuing or event which with the passing of time or giving of
notice or both would become an Event of Default hereunder has occurred and is
continuing. Lender shall consolidate all Interim Loans and convert them to a
Term Loan evidenced by a Term Note or Notes. Whether or not a Term Loan is
evidenced by one or more Term Notes shall be agreed between Lender and Borrower,
or in the absence of such an agreement, as decided by Lender,
<PAGE>
 
in the exercise of its reasonable business judgment.

(d)  In the event that the amount loan pursuant to the Interim Loans is less
than the Loan Amount, subject to Borrowers compliance with the terms and
conditions of this Loan and Security Agreement (including the satisfaction of
the conditions of borrowing set forth in Section 7 of this Loan and Security
Agreement including but not limited to providing Lender with a description of
the items of Equipment), Lender shall disburse to Borrower the balance of the
Loan Amount on the same date that the Interim Loans are converted into a term
loan.

3.   METHOD FOR BORROWING ON INTERIM LOAN.  Borrower shall give Lender at least
     ------------------------------------
five (5) business days written notice of a request for the disbursement of an
Interim Loan ("Request"), specifying the date on which the Interim Loan is to be
disbursed. Such Request shall be in the form attached hereto as Exhibit "C".
Such Request shall be accompanied by an original copy of the invoice or invoices
to be paid from the Interim Loan. Such Request shall constitute a representation
and warranty by the Borrower that (i) as of the date of the Request no Event of
Default or event which with the passing of time or the giving of notice or both
would constitute an Event of Default hereunder has occurred and is continuing
and (ii) in the event items of Equipment have been delivered to Borrower,
Borrower has unconditionally accepted the Equipment from the vendor thereof.
Subject to the conditions of this Loan and Security Agreement, Lender shall
disburse the Interim Loan to the invoicing party, or if Borrower shall have paid
the amount of such invoice, Lender shall reimburse Borrower, upon receipt of
proof of payment from Borrower.

4.   CROSS COLLATERAL/CROSS DEFAULT.  All Collateral shall secure the payment
     ------------------------------
and performance of all of Borrower's liabilities and obligations to Lender
hereunder and under any of the loan documents relating hereto including, but not
limited to all Interim Notes and all Term Notes (the Loan and Security
Agreement, the Interim Notes, the Term Notes, the Supplemental Security
Agreement(s) and all other loan documents relating hereto may be referred to
herein collectively as the Loan Documents"). Lender's security interest in the
Collateral shall not be terminated until and unless all of Borrower's
obligations to Lender under any of the Loan Documents are fully paid and
performed. The occurrence of an event of default under any other of the Loan
Documents shall be deemed to be an Event of Default hereunder and an Event of
Default hereunder shall be deemed to be an event of default under any other of
the Loan Documents.

3,346,590.16                                                   November 18, 1997


     FOR VALUED RECEIVED, the undersigned PointCast Incorporated, ("Maker"),
promises to pay to the order of MetLife Capital Corporation, ("Payee"), at its
office at P.O. Box C-97550, Bellevue, Washington 98009, the principal sum of
Three Million Three Hundred Forty-Six Thousand Five Hundred Ninety and 16/100
($3,346,590.16) Dollars together with interest on unpaid principal from the date
of disbursement of such principal amount until payment in full at a rate of Nine
and 70/100 percent (9.70%) per annum ("Rate") computed on the basis of a 360 day
year of twelve consecutive thirty day months.  Interest hereunder shall be paid
on the unpaid principal, together with principal, in Thirty-Six (36)
installments of One Hundred Six Thousand Six Hundred Fifty-Two and 20/100
($106,652.20) commencing on November 21, 1997 and monthly thereafter until
October 21, 2000, on which date the entire balance of principal and interest
unpaid shall be due and payable.  It is agreed that each installment, when paid,
shall be applied by the holder hereof, first so much as shall be required to the
payment of interest accrued as specified hereto, and the balance thereof to the
repayment of the principal sum.

     The Rate expressed above will be adjusted at Loan Closing in accordance
with the following formula:  The interest rate shall be fixed at 399 basis
points (3.99%) over the then weekly average yield of Two (2) year U.S. Treasury
Constant Maturities as published in the Federal Reserve Statistical Release H.
15[519].

     Except as may be otherwise expressly provided herein, this Note may not be
prepaid in whole or in part, except with the prior written consent of Payee.
Maker shall have the privilege of prepaying all (but not part) of the then
outstanding balance under this Note on September 21, 1999 or on any installment
due date thereafter, subject to giving thirty (30) days prior written notice to
Payee specifying the date of prepayment and further subject to payment of a
prepayment premium equal to the amount, if any, required to offset the adverse
impact to Payee of any decline in interest rates.  The prepayment premium is
determined by (i) calculating the decrease, expressed in basis points (but not
less than zero) in the current weekly average yield for Two (2)-year U.S.
Treasury Constant Maturities as published in Federal Reserve Statistical Release
                                             -----------------------------------
15(519) (the

"Index") from the weekly average yield of 5.71% as of November 21, 1997 to the
Friday (or, if Friday is not a business day, the last business day) of the week
immediately preceding the prepayment date (ii) dividing the difference by 100,
(iii) multiplying the result by the applicable "Premium Factor" set forth below,
and (iv) multiplying the product by the principal to be prepaid.  Any prepayment
shall be applied first to the prepayment premium, if any, next to accrued
interest and late charges (if any), and thereafter to the principal when
outstanding.  The Premium Factor shall be the amount shown on the following
chart for the month in which prepayment occurs.

<TABLE>
<CAPTION>
           NUMBER OF MONTHS REMAINING      (YEARS)      PREMIUM FACTOR
           <S>                             <C>          <C>
                      18 - 13                 (2)              .010
                      12 - 1                  (1)              .005
</TABLE>

In the event the Federal Reserve Board ceases to publish Statistical Release H
15(519), then the decrease in Two (2)-Year U.S. Treasury Constant Maturities
will be determined from another source designated by Payee.

     If Maker shall have given to Payee notice of Makers intention to so prepay,
Maker Shall not then be entitled to withdraw such notice, and the indebtedness
proposed to be prepaid in such notice together with the aforesaid prepayment
fee, if applicable, shall be due and payable upon the date specified for such
prepayment in such notice.  Upon the occurrence of an Event of Default and
acceleration of payment of indebtedness evidenced hereby during a period open to
prepayment, Maker shall pay to Payee, in addition to any and all other sums due
and payable hereunder, as liquidated damages for the loss of Payee's investment
and not as a penalty, an amount equal to the prepayment fee which would have
been payable hereunder in such date of acceleration in the event of a 
<PAGE>
 
voluntary prepayment. Maker and Payee agree that the foregoing amounts do not
constitute penalties but rather constitute reasonable calculations of the
investment loss that would be sustained by Payee in the event of such
prepayment.

     It is specifically understood and agreed by Maker that, in the event of a
default under this Note or under any instrument securing the Note, a tender of
payment of the unpaid principal and accrued interest then outstanding shall be
deemed a prepayment, and, accordingly, said tender must include the premium
herein above required, or if said tender is made prior to the time this
privilege is operative, then said tender must include a premium equal to six (6)
months' interest at the Rate computed on the principal amount so tendered.  It
is further understood and agreed by Maker that Payee shall not be obligated to
accept said tender, and said tender shall for all purposes be deemed ineffectual
and deficient, unless said tender shall include the premium herein above
required.

     In the event that Payee does not receive any payment on the date due, Maker
will pay Payee a late charge of five percent (5%) of the payment outstanding
together with the payment and, provided said sum is received within ten (10)
days of the date due, Payee agrees not to demand immediate payment of the whole
sum of principal and interest as otherwise permitted herein.

     If, from any circumstances whatsoever, payment of any obligation due under
this Note at the time such performance shall be due shall involve exceeding the
maximum amount currently prescribed by any applicable usury statute or any other
applicable law, then such obligation shall be reduced to such maximum amount, so
that in no event shall any payment be possible under this Note, or under any
other instrument evidencing or securing the indebtedness evidenced hereby, that
is in excess of such maximum amount.

     In the event that an Event of Default shall occur under the Loan and
Security Agreement (as hereinafter defined) or any other instrument now or
hereafter securing repayment hereof, following any required notice and/or the
expiration of any applicable period of grace, then, and in such event, the
principal indebtedness evidenced hereby, and any other sums advanced hereunder,
together with all unpaid interest accrued thereon, shall, at the option of
Payee, at once become due and payable and may be collected forthwith, regardless
of the stipulated date of maturity.  TIME IS OF THE ESSENCE WITH RESPECT TO THIS
NOTE.  Interest shall accrue on the outstanding principal for so long as such
default continues, regardless of whether or not there has been an acceleration
of the indebtedness evidenced hereby as set forth herein, at the rate equal to
the lesser of fifteen percent (15%) per annum or the maximum rate allowable
under law.  All such interest shall be paid at the time of and as a condition
precedent to the curing of any such default should Payee, at its sole option,
allow such default to be cured.  In the event this Note, or any part thereof, is
collected by or through an attorney-at-law, Maker agrees to pay all costs of
collection including, but not limited to, reasonable attorneys' fees, whether or
not suit is filed.

2.   LOAN AND TERMS OF PAYMENTS.
     --------------------------

     For value received, Borrower promises to pay to the order of Bank such
amount, as provided for below, together with interest, as provided for below.

     2.1  Upon the request of Borrower, made at any time and from time to time
during the term hereof, and so long as no Event of Default has occurred, Bank
shall lend to Borrower an amount equal to the Borrowing Base; provided, however,
that in no event shall Bank be obligated to make advances to Borrower under this
Section 2.1 whenever the Daily Balance exceeds, at any time, either the
Borrowing Base or the sum of Five Million and no/100 Dollars ($5,000,000), such
amount being referred to herein as an "Overadvance".

     2.2  Except as hereinbelow provided, the Credit shall bear interest, on the
Daily Balance owing, at a rate of no (0.00) percentage points per annum above
the Base Rate (the "Rate").  The Credit shall bear interest, from and after the
occurrence of an Event of Default and without constituting a waiver of any such
Event of Default, on the Daily Balance owing, at a rate of three (3) percentage
points per annum above the Rate.  All interest chargeable under this Agreement
that is based upon a per annum calculation shall be computed on the basis of a
three hundred sixty (360) day year for actual days elapsed.

          The Base Rate as of the date of this Agreement is eight and 500/1000
percent (8.50%) per annum.  In the event that the Base Rate announced is, from
time to time hereafter changed, adjustment in the Rate shall be made and based
on the Base Rate in effect on the date of such change.  The Rate, as adjusted,
shall apply to the Credit until the Base Rate is adjusted again.  All interest
payable by Borrower under the Credit shall be due and payable on the first day
of each calendar month during the term of the Agreement and Bank may, at its
option, elect to treat such interest and any and all Bank Expenses as advances
under the Credit, which amounts shall thereupon constitute Obligations and shall
thereafter accrue interest at the rate applicable to the Credit under the terms
of the Agreement.

3.   TERM.
     ----

     3.1  This Agreement shall remain in full force and effect until March 31,
1999, or until terminated by notice by Borrower. Notice of such termination by
Borrower shall be effectuated by providing Bank written notice not less than
three (3) days prior to the effective date of such termination, addressed to the
Bank at the address set forth herein and the termination shall be effective as
of the date so fixed in such notice. Notwithstanding the foregoing, while an
Event of Default is continuing, Bank may terminate this Agreement at any time
without notice. Notwithstanding the foregoing, should either Bank or Borrower
become insolvent or unable to meet its debts as they mature, or fail, suspend,
or go out of business, the other party shall have the right to terminate this
Agreement at any time without notice. On the date of termination all Obligations
shall become immediately due and payable without notice or demand; no notice of
termination by Borrower shall be effective until Borrower shall have paid all
Obligations (other than inchoate indemnity obligations) to Bank in full.
Notwithstanding termination, until all Obligations (other than inchoate
indemnity obligations) have been fully satisfied, Bank shall retain its security
interest in all existing

Collateral and Collateral arising thereafter, and Borrower shall continue to
perform all of its Obligations.

     3.2  After termination and when Bank has received payment in full of
Borrower's Obligations to Bank, Bank shall reassign to Borrower all Collateral
held by Bank, and shall execute a termination of all security agreements and
security interests given by Borrower to Bank, upon the execution and delivery of
mutual general releases.

4.   CREATION OF SECURITY INTEREST.
     -----------------------------

     4.1  Borrower hereby grants to Bank a continuing security interest in all
presently existing and hereafter arising Collateral in order to secure prompt
repayment of any and all Obligations owed by Borrower to Bank and in order to
secure prompt performance by Borrower of each and all of its covenants and
Obligations under the Agreement and otherwise created. Bank's security interest
in the Collateral shall attach to all Collateral without further act on the part
of Bank or Borrower. In the event that any Collateral, including proceeds, is
evidenced by or consists of a letter of credit, advice of credit, instrument,
money, negotiable documents, chattel paper or similar property (collectively
"Negotiable Collateral"), Borrower shall, immediately upon receipt thereof,
endorse and assign such Negotiable Collateral over to Bank and deliver actual
physical possession of the Negotiable Collateral to Bank.

     4.2  Bank's security interest in Receivables shall attach to all
Receivables without further act on the part of Bank or Borrower.  Upon request
from Bank, Borrower shall provide Bank with schedules describing all Receivables
created or acquired by Borrower (including without limitation agings listing the
names and addresses of, and amounts owing by date by account debtors), provided,
however, Borrower's failure to execute and deliver such schedules shall not
affect or limit Bank's security interest and other rights in and to the
Receivables.  Together with each schedule, Borrower shall furnish Bank with
copies of Borrower's customers' invoices or the equivalent, and original
shipping or delivery receipts for all merchandise sold, and Borrower warrants
the genuineness thereof.  Upon the occurrence and during the continuance of an
Event of Default, Bank or Bank's designee may notify customers or account
debtors of collection costs and expenses to Borrower's account but, unless and
until Bank does so or gives Borrower other written instructions, Borrower shall
collect all Receivables for Bank, receive in trust all payments thereon as
Bank's trustee, and, if so requested to do so from Bank, Borrower shall
immediately deliver said payments to Bank in their original form as received
from the account debtor and all letters of credit, advices of credit,
instruments, documents, chattel paper or any similar property evidencing or
constituting Collateral.  The receipt of any check or other item of payment by
Bank shall not be considered a payment on account until such check is honored
when presented for payment.

     4.3  Bank's security interest in Inventory shall attach to all Inventory
without further act on the part of Bank or Borrower.  Upon Bank's request
following the occurrence and during the continuance of an Event of Default
Borrower will from time to time at Borrower's expense pledge, assemble and
deliver such Inventory to Bank or to a third party

as Bank's bailee; or hold the same in trust for Bank's account or store the same
in a warehouse in Bank's name; or deliver to Bank documents of title
representing said Inventory; or evidence of Bank's security interest in some
other manner acceptable to Bank.

     4.4  Borrower shall execute and deliver to Bank concurrently with
Borrower's execution of this Agreement, and at any time or times hereafter at
the request of Bank, all financing statements, continuation financing
statements, security agreements, mortgages, assignments, certificates of title,
affidavits, reports, notices, schedules of accounts, letters of authority and
all other documents that Bank may request, in form satisfactory to Bank, to
perfect and maintain perfected Bank's security interest in the Collateral and in
order to fully consummate all of the transactions contemplated under this
Agreement.  Effective upon the occurrence and during the continuance of an Event
of Default, Borrower hereby irrevocably makes, constitutes and appoints Bank
(and any of Bank's officers, employees or agents designated by Bank) as
Borrower's true and lawful attorney-in-fact with owner to sign the name of
Borrower on any financing statements, continuation financing statements,
security agreement, mortgage, assignment, certificate of title, affidavit,
letter of authority, notice of other similar documents which must be executed
and/or filed in order to perfect or continue perfected Bank's security interest
in the Collateral.

     Borrower shall make appropriate entries in Borrower's Books disclosing
Bank's security interest in the Receivables.  Bank (through any of its officers,
employees or agents) all have the right at any time or times hereafter during
Borrower's usual business hours, or during the usual business hours of any third
party having control over the records of Borrower, to inspect and verify
Borrower's Books in order to verify the amount or condition of, or any other
matter, relating to, said Collateral and Borrower's financial condition.

     4.5  Effective only while an Event of Default is continuing, Borrower
appoints Bank or any other person whom Bank may designate as Borrower's
attorney-in-fact, with power to endorse Borrower's name on any checks, notes,
acceptances, money order, drafts or other forms of payment or security that may
come into Bank's possession; to sign Borrower's name on any invoice or bill of
lading relating to any Receivables, on drafts against account debtors, on
schedules and assignments of Receivables, on verifications of Receivables and on
notices to account debtors; to establish a lock box arrangement and/or to notify
the post office authorities to change the address for delivery of Borrower's
mail addressed to Borrower to an address designated by Bank, to receive and open
all mail addressed to Borrower, and to retain all mail related to the Collateral
and forward all other mail to Borrower; to send, whether in writing or by
telephone, requests for verification of Receivables; and to do all things
necessary to carry out this Agreement.  Borrower ratifies and approves all acts
of the attorney-in-fact.  Neither Bank nor its attorney-in-fact will be liable
for any acts or omissions or for any error of judgement or mistake of fact or
law.  This power being coupled with an interest, is irrevocable so long as any
Receivables in which Bank has a security interest remain unpaid and until the
Obligations have been fully satisfied.

     4.6  Effective only while an Event of Default is continuing, in order to
protect or prefect any security interest which Borrower is granted hereunder,
Borrower may, in its sole discretion, discharge any lien or encumbrance or bond
the same, pay any insurance, maintain

guards, warehousemen, or any personnel to protect the Collateral, pay any
service bureau, or, obtain any records, and all costs for the same shall be
added to the Obligations and shall be payable on demand.

     4.7  Borrower agrees that Bank may provide information relating to this
Agreement or relating to Borrower to Bank's parent, affiliates, subsidiaries and
services providers.

     Notwithstanding any provision of this Agreement to the contrary, prior to
the occurrence of an Event of Default, Borrower shall not be required to
disclose, permit inspection, examination, copying or making extracts of, or
discuss, any document, information or other matter that (i) constitutes non-
financial trade secrets or non-financial proprietary information, or (ii) the
disclosure of which to Bank, or their designated representative, is then
prohibited by (a) law, or (b) an agreement binding on the Borrower that was not
entered into by the Borrower for the primary purpose of concealing information
from the Bank.

     In handling any confidential information Bank and all employees and agents
of Bank, including but not limited to accountants, shall exercise the same
degree of care that it exercises with respect to its own proprietary information
of the same types to maintain the confidentiality of any non-public information
thereby received or received pursuant to this Agreement except that disclosure
of such information may be made (i) to the subsidiaries or affiliates of Bank in
connection with their present or prospective business relations with Borrower,
(ii) to prospective transferees or purchasers of any interest in the
Obligations, provided that they have entered into a comparable confidentiality
agreement in favor of Borrower and have delivered a copy to Borrower, (iii) as
required by law, regulations, rule or order, subpoena, judicial order or similar
order, (iv) as may be required in connection with the examination, audit or
similar investigation of Bank and (v) as Bank may determine in connection with
the enforcement of any remedies hereunder. Confidential information hereunder
shall not include information that either: (a) is in the public domain or in the
knowledge or possession of Bank when disclosed to Bank, or becomes part of the
public domain after disclosure to Bank through no fault of Bank; or (b) is
disclosed to Bank by a third party, provided Bank does not have actual knowledge
that such third party is prohibited from disclosing such information.

deductibles on any such policies. Borrower shall also keep and maintain public

payment for the proceeds of such policies of insurance and for making all
determinations and decisions with respect to such policies of insurance.

consent.  Each such insurer shall agree by endorsement upon the policy or
policies of insurance issued by it to Borrower as required above, or by
independent instruments furnished to Bank, that it will give Bank at least ten
(10) days written notice before any such policy or policies of insurance shall
be altered or canceled, and that no act or default of Borrower, or any other
person, shall affect the right of Bank to recover under such policy or policies
of insurance required above or to pay any premium in whole or in part relating
thereto.  Bank, without waiving or releasing any Obligations or any Event of
Default, may, but shall have no obligation to do so, obtain and maintain such
policies of insurance and pay such premiums and take any other action with
respect to such policies which Bank deems advisable.  All sums so disbursed by
Bank, as well as reasonable attorneys' fees, court costs, expenses and other

action under California Code of Civil Procedure 726, apply any and all amounts
maintained by Borrower as deposit accounts (as that term is defined under 9105
of the Uniform Commercial Code) or other accounts that Borrower maintains with
Bank against the Obligations.

     8.2  Bank's rights and remedies under this Agreement and all other
agreements shall be cumulative.  Bank shall have all other rights and remedies
not inconsistent herewith as provided by law or in equity.  No exercise by Bank
of one right or remedy shall be deemed an election, and no waiver by Bank of any
default on Borrower's part shall be deemed a continuing waiver.  No delay by
Bank shall constitute a waiver, election or acquiescence by Bank.

                            (Accounts & Inventory)


9.   TAXES AND EXPENSES REGARDING BORROWER'S PROPERTY.
     ------------------------------------------------

If Borrower fails to pay promptly when due to another person or entity, monies
which Borrower is required to pay by reason of any provision in this Agreement,
Bank may, but need not, pay the same and charge Borrower's account therefor, and
Borrower shall promptly reimburse Bank. All such sums shall become additional
indebtedness owing to Bank, shall bear interest at the rate hereinabove
provided, and shall be secured by all Collateral. Any payments made by Bank
shall not constitute (i) an agreement by it to make similar payments in the
future; or (ii) a waiver by Bank of any default under this Agreement. Bank need
not inquire as to, or contest the validity of, any such expense, tax security
interest, encumbrance or lien and the receipt of the usual official notice of
the payment thereof shall be conclusive evidence that the same was validly due
and owing. Such payments shall constitute Bank Expenses and additional advances
to Borrower.

10.  WAIVERS.
     -------

     10.1 Borrower agrees that checks and other instruments received by Bank in
payment or on account of Borrower's Obligations constitute only conditional
payment until such items are actually paid to Bank and Borrower waives the right
to direct the application of any and all payments at any time or times hereafter
received by Bank on account of Borrower's Obligations and Borrower agrees that
Bank shall have the continuing exclusive right to apply and reapply such
payments in any manner as Bank may deem advisable, notwithstanding any entry by
Bank upon its books.

     10.2 Borrower waives demand, protest, notice of protest, notice of default
or dishonor, notice of payment and nonpayment, notice of any default, nonpayment
at maturity, release, compromise, settlement, extension or renewal of any or all
commercial paper, accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be liable.

     10.3 Bank shall not in any way or manner be liable or responsible for (a)
the safekeeping of the Inventory; (b) any loss or damage thereto occurring or
arising in any manner or fashion from any cause; (c) any diminution in the value
thereof; or (d) any act or default of any carrier, warehouseman, bailee,
forwarding agency or other person whomsoever.  All risk of loss, damage or
destruction of Inventory shall be borne by Borrower.

     10.4 Borrower waives the right and the right to assert a confidential
relationship, if any, it may have with any accountant, accounting firm and/or
service bureau or consultant in connection with any information requested by
Bank pursuant to or in accordance with this Agreement, and agrees that a Bank
may contact directly any such accountants, accounting firm and/or service bureau
or consultant in order to obtain such information.

     10.5 BORROWER AND BANK EACH WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION
OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY TRANSACTION HEREUNDER, OR
CONTEMPLATED HEREUNDER, OR ANY OTHER

                            (Accounts & Inventory)

CLAIM (INCLUDING TORT OR BREACH OF DUTY CLAIMS) OR DISPUTE HOWSOEVER ARISING
BETWEEN BANK AND BORROWER.

     10.6 In the event that Bank elects to waive any rights or remedies
hereunder, or compliance with any of the terms hereof, or delays or fails to
pursue or enforce any terms, such waiver, delay or failure to pursue or enforce
shall only be effective with respect to that single act and shall not be
construed to affect any subsequent transactions or Bank's right to later pursue
such rights and remedies.

11.  ONE CONTINUING LOAN TRANSACTION.
     -------------------------------

     All loans and advances heretofore, now or at any time or times hereafter
made by Bank to Borrower under this Agreement or any other agreement between
Bank and Borrower, shall constitute one loan secured by Bank's security
interests in the Collateral and by all other security interests, liens,
encumbrances heretofore, now or from time to time hereafter granted by Borrower
to Bank.

     Notwithstanding the above, (i) to the extent that any portion of the
Obligations are a consumer loan, that portion shall not be secured by any deed
or trust or mortgage on or other security interest in the Borrower's principal
dwelling which is not a purchase money security interest as to that portion,
unless expressly provided to the contrary in another place, or (ii) if the
Borrower (or any of them) has (have) given or give(s) Bank a deed of trust or
mortgage covering real property, that deed of trust or mortgage shall not secure
the loan and any other Obligation of the Borrower (or any of them), unless
expressly provided to the contrary in another place.

12.  NOTICES.
     -------

     Unless otherwise provided in this Agreement, all notices or demands by
either party on the other relating to this Agreement shall be in writing and
sent by regular United States mail, postage prepaid, properly addressed to
Borrower or to Bank at the addresses stated in this Agreement, or to such other
addresses as Borrower or Bank may from time to time specify to the other in
writing.  Requests to Borrower by Bank hereunder may be made orally.

13.  AUTHORIZATION TO DISBURSE.
     -------------------------

     Bank is hereby authorized to make loans and advances hereunder upon
telephonic or other instructions received from anyone purporting to be an
officer, employee, or representative of Borrower, or at the discretion of Bank
if said loans and advances are necessary to meet any Obligations of Borrower to
Bank.  Bank shall have no duty to make inquiry or verify the authority of any
such party, and Borrower shall hold the Bank harmless from any damage, claims or
Liability by reason of Bank's honor of, or failure to honor, any such
instructions.

14.  DESTRUCTION OF BORROWER'S DOCUMENTS
     -----------------------------------

     Any documents, schedules, invoices or other papers delivered to Bank, may
be destroyed or otherwise disposed of by Bank six (6) months after they are
delivered to or received by Bank, unless Borrower requests, in writing, the
return of the said documents, schedules, invoices or other papers and makes
arrangements, at Borrower's expense, for their return.

15.  CHOICE OF LAW.
     -------------

     The validity of this Agreement, its construction, interpretation and
enforcement, and the rights of the parties hereunder and concerning the
Collateral, shall be determined according to the laws of the State of
California.  The parties agree that all actions or proceedings arising in
connection with this Agreement shall be tried and litigated only in the state
and federal courts in the Northern District of California or County of Santa
Clara.

16.  GENERAL PROVISIONS.

the Borrower and accepted and executed by Bank at its Headquarter Office.

     16.2 This Agreement shall bind and inure to the benefit of the respective
successors and assigns of each of the parties, provided, however, that Borrower

consent to an assignment by Bank shall release Borrower or any guarantor from
their Obligations to Bank.  Bank may assign this Agreement and its rights and
duties hereunder.  Bank reserves the right to sell, assign, transfer, negotiate
or grant participations in all or any part of, or any interest in Bank's rights

of all parties hereto.  When permitted by the context, the singular includes the
plural and vice versa.
