                          FIRST AMENDMENT TO LEASE AND

                       ASSIGNMENT AND ASSUMPTION OF LEASE

        THIS FIRST AMENDMENT TO LEASE AND ASSIGNMENT AND ASSUMPTION OF LEASE
(this "Agreement") is made and entered into this 7th day of December 2001, by
and among BOHANNON DEVELOPMENT COMPANY, a California corporation ("Bohannon"),
IPRINT TECHNOLOGIES, INC. ("iPrint") and GERON CORPORATION ("Geron)
(collectively, the "Parties").

                                    RECITALS

        A. Bohannon, as the landlord, and iPrint (previously known as
iPrint.com, inc.), as the tenant, are parties to that certain lease dated March
7, 2000 (the "Lease"), for premises located at 255 Constitution Drive, Menlo
Park, California (the "Premises).

        B. iPrint desires to assign and delegate all of its rights and
obligations under the Lease to Geron, and Geron desires to accept such
assignment and to assume iPrint's obligations under the Lease.

        C. In connection with such assignment and assumption, Bohannon and Geron
desire to amend the Lease in certain respects, on the terms and conditions
hereinafter set forth.

        D. This Agreement is intended to be a contemporaneous exchange for new
value.

        NOW THEREFORE, in consideration of the mutual promises contained herein,
the Parties agree as hereinafter set forth.

                                    AGREEMENT

        1. Effective Date. This Agreement shall become effective on December 7,
2001 (the "Effective Date").

        2. Assignment, Assumption and Consent. Subject to the terms and
conditions herein, from and after the Effective Date, iPrint hereby assigns and
transfers to Geron all of iPrint's right, title, and interest in, to and under
the Lease. Subject to the terms and conditions herein, Geron hereby assumes all
of the obligations of iPrint under the Lease to be performed by the Tenant under
the Lease and agrees to be bound by all of the terms, covenants, conditions, and
provisions of the Lease, as amended pursuant to this Agreement. Bohannon hereby
consents to the foregoing assignment and assumption of Lease and agrees that
from and after the Effective Date, except as set forth in Sections 3, 4 and 14
below, iPrint shall be released and discharged from all liability under the
Lease. Notwithstanding the foregoing or anything else to the contrary in this
Agreement, the Parties acknowledge and agree that Geron shall pay the entire
amount of December Base Rent, without proration, as set forth in Section 8 of
this Agreement, and iPrint shall have no obligations or responsibilities
therefor.



                                       1


        3. Lease Discharge Payment. As consideration for Bohannon's execution
and delivery of this Agreement, iPrint shall make the following payments in the
aggregate amount of Four Hundred Eighty Thousand Dollars ($480,000) (the "Lease
Discharge Payment") to be delivered in two (2) installments, the first of which
in the amount of Two Hundred Eighty Thousand Dollars ($280,000) shall be paid to
Bohannon on or before December 7, 2001, and the second of which in the amount of
Two Hundred Thousand Dollars ($200,000) shall be due and payable to Bohannon on
January 2, 2002. In addition, iPrint shall deliver to Bohannon, at no cost to
Bohannon, sixty thousand (60,000) shares of the common stock of iPrint (the
"Stock") as soon as reasonably possible, but in no event later than
January 11, 2002. Geron shall have no obligation whatsoever with respect to the
Lease Discharge Payment or with respect to any other obligation of iPrint under
this Agreement.

        4. Security for Consideration. The Parties acknowledge that iPrint
previously provided Bohannon with a standby letter of credit in the amount of
Two Hundred Fifty Thousand Dollars ($250,000) issued by Imperial Bank (the
"Letter of Credit"), which was delivered to Bohannon by iPrint in accordance
with Section 2.4 of the Lease. The Parties acknowledge and agree that after the
Effective Date the Letter of Credit shall secure only the obligations of iPrint
set forth in Section 3 above and not the obligations of Geron as the successor
Tenant under the Lease.

        5. Default by iPrint. In the event that iPrint fails to deliver (a) any
installment of the Lease Discharge Payment or (b) the entire amount of Stock as
set forth in Section 3 above, and if such failure continues for three (3)
business days after written notice is given by Bohannon to iPrint specifying
such failure, then such failure shall be deemed a default ("Default"); provided,
however, that a Default shall be deemed a default only by iPrint (and not by
Geron), and Bohannon shall have no right to terminate the Lease or otherwise
take any action against Geron with respect to such Default by iPrint. In the
event that the Default results from the failure of iPrint to deliver any portion
of the Lease Discharge Payment (a "Payment Default"), Bohannon shall thereafter
be permitted to draw on the Letter of Credit in an amount equal to the
installment of the Lease Discharge Payment that has not been timely paid. In the
event that the Default results from the failure of iPrint to deliver the Stock
(a "Stock Delivery Default"), Bohannon shall thereafter be permitted to draw on
the Letter of Credit in the amount of Fifty Thousand Dollars ($50,000) (the
"Deemed Value of the Stock"), which amount iPrint and Bohannon acknowledge and
agree to be a reasonable estimate of damages related to such Default as actual
damages cannot be ascertained with certainty. If Bohannon draws on (and receives
payment under) the Letter of Credit as a result of a Payment Default or a Stock
Delivery Default, and if the amount received under the Letter of Credit is
sufficient to cure the Default, then payment of such amount shall constitute
Bohannon's sole and exclusive remedy for such defaults; provided, however, if a
petition seeking relief under the United States Bankruptcy Code is filed by or
against iPrint within ninety (90) days after the later of the date by which
iPrint delivers the Stock or makes the final Lease Discharge Payment, then
Bohannon shall have the right to draw on the Letter of Credit in the full amount
thereof. In such event, Bohannon shall be required to return to iPrint (or the
bankruptcy estate of iPrint, as the case may be) any proceeds of the Letter of
Credit to the extent such proceeds exceed the amounts, if any, of the Lease
Discharge Payment or the Deemed Value of the Stock that have been set aside
under applicable bankruptcy law. In no event shall Bohannon be entitled to draw
on the Letter of Credit as the result of any default by




                                       2


Geron under the Lease, it being agreed that the sole basis for Bohannon to draw
upon the Letter of Credit shall be a Default as set forth herein.
Notwithstanding the foregoing, if Bohannon attempts to draw on the Letter of
Credit in an amount necessary to cure the Default, and if the Letter of Credit
is dishonored by the issuing bank or if the amount available to Bohannon by
drawing on the Letter of Credit is insufficient to cure the Default, then iPrint
shall pay Bohannon on the first day of each month during the remaining term of
the Lease an amount (the "Shortfall Base Rent Payments") equal to (a) the
monthly Base Rent, as set forth in the Original Lease, MINUS (b) the monthly
Base Rent required to be paid by Geron, as set forth in this Agreement, in each
case for the period starting on the date of such default and continuing through
the term of the Lease; provided, however, that iPrint shall receive a credit
against the Shortfall Base Rent Payment for any Lease Discharge Payment that has
been made prior to such default. Upon payment to Bohannon of the entire Lease
Discharge Payment and delivery of the entire amount of Stock as set forth above,
Bohannon shall have no further rights to draws under the Letter of Credit for
any purposes whatsoever, and the original Letter of Credit shall be returned to
iPrint, within one hundred ten (110) days after the last payment of any portion
of the Lease Discharge Payment, upon iPrint's request.

        6. Release of Claims. Bohannon and iPrint acknowledge Paragraphs 1 and 2
of the Letter of Credit, setting forth documents to be delivered to the issuing
bank prior to a draw on the Letter of Credit, provide as follows:

        "1. THE ORIGINAL OF THIS STANDBY LETTER OF CREDIT AND AMENDMENT (S) IF
ANY.

        2. BENEFICIARY'S STATEMENT DATED AND SIGNED BY AN AUTHORIZED OFFICER
CERTIFYING THAT (1) IPRINT.COM, INC IS IN DEFAULT UNDER ONE OR MORE TERMS OF
THAT CERTAIN LEASE AGREEMENT DATED MARCH 7, 2000 THAT EXISTS BETWEEN IPRINT.COM,
INC. AND BENEFICIARY, (2) BENEFICIARY HAS PROVIDED TO IPRINT.COM, INC.ALL
NOTICES REQUIRED UNDER THE LEASE, AND (3) ANY APPLICABLE CURE PERIOD HAS LAPSED
WITHOUT REMEDY, AND (4) THE BENEFICIARY IS AUTHORIZED TO DRAW DOWN ON THE LETTER
OF CREDIT."

        Bohannon and iPrint further acknowledge that although Paragraphs 1 and 2
refer to a default or event of default under the Lease, the Parties have agreed
under Section 4 of this Agreement that, from and after the Effective Date, the
Letter of Credit shall be held solely as security for iPrint's obligation to
deliver the Lease Discharge Payment and the Stock. Notwithstanding the terms of
the Letter of Credit to the contrary, in the event of a Default under this
Agreement, iPrint authorizes Bohannon to submit all documents to the issuing
bank in accordance with Paragraphs 1 and 2 of the Letter of Credit (and to make
all statements referred to in Paragraph 2 of the Letter of Credit) as though a
default had occurred under the Lease. Provided Bohannon makes a request for
payment under the Letter of Credit in accordance with this Agreement, iPrint
shall have no claims or actions against Bohannon and shall hold Bohannon
harmless for the submission of documents to the issuing bank in accordance with
Sections 4, 5 and 6 of this Agreement.



                                       3

                       April 30, 2005


        9. Increase of Base Rent. Notwithstanding Section 2.1.B or any other

                option described in this Section 1.3, and has not been, in
                default under any of the terms and conditions hereof, which
                default has not been cured within the applicable cure periods
                set forth in Article 13 below, Tenant shall have the option to
                extend the demised term of this Lease for one (1) additional
                period of twenty-one (21) months (to January 31, 2007) (the
                "First Extension Term") upon the terms and conditions set forth
                herein:

                        A. Tenant shall exercise such option by written notice
                to Landlord given at least two hundred seventy (270) days prior
                to the expiration of the original demised term; provided that,
                if during the last two (2) years of the initial demised term,
                Landlord should receive a bona fide offer to lease the demised
                premises at the end of the initial demised term from another
                tenant, which offer Landlord is prepared to accept, then Tenant
                shall have ten (10) business days from receipt of notice from
                Landlord that Landlord has received such an offer (together with
                a copy of such bona fide offer) to exercise its option upon the
                terms and conditions



                                       4


                of this Section 1.3. Should Tenant fail to exercise its option
                to extend the lease within ten (10) business days, then said
                option shall be null and void.

                        B. Base rent for the First Extension Term shall be

                        E. The option to extend may only be exercised by Geron
                Corporation provided that Geron may exercise the option on its
                behalf if Geron has subleased any or all of the demised premises
                and Landlord has consented to such sublease. The option cannot
                be transferred nor can it be exercised by Geron if Geron has

                and manufacturing, and for no other purposes without Landlord's
                prior written consent.

                        Landlord may carry any deductible under said insurance
                        Landlord elects; provided that Landlord's obligation to
                        repair will include the amount of said deductible and
                        Tenant agrees to reimburse Landlord for any such
                        deductible used for repair up to the amount of
                        $10,000.00.

                        employees, agents, invitees, or contractors to the
                        extent not covered by insurance (exclusive of any
                        deductibles referenced in Section 10.1) carried, or
                        required to be carried, by Landlord or Tenant hereunder.

                10.7. Section 12.2 of the Lease is amended to add the following
        language:

                        customers while working or visiting Tenant; provided
                        that Landlord shall have no obligation to police said
                        Parking Areas or enforce Tenant's right to exclusive use
                        thereof.

Bohannon under the terms of such Section 9.1, and iPrint specifically confirms
and agrees that its indemnities under the Lease will remain fully in force with
respect to any such acts, omissions or events. Geron does not assume, and shall

the Lease, and Bohannon shall have no remedies against Geron, under the Lease or
otherwise, for any failure by iPrint to perform under such indemnities.

        15. Binding Effect. This Agreement amends the Lease and, except as
specifically set forth herein, in the event of any inconsistency between this
Agreement and the Lease, the terms of this Agreement shall be controlling.
Unless otherwise defined, all terms used in this Agreement shall have the same
meanings as given them in the Lease.

        16. Captions. The title of the various articles of this Agreement are
