                                LEASE EXPANSION
                                        

This Second Amendment to Lease Agreement (the "Amendment") is made and entered
into as of December 2, 1997, by  and  between LINCOLN  MENLO  PHASE I
ASSOCIATES  LIMITED,  a  California  limited  partnership "Landlord"), and JET
FAX, INC., a Delaware corporation ("Tenant"), with reference to the following
facts.



                                    RECITALS


A .  Landlord and Tenant have entered into that certain Lease Agreement dated as
of April 4, 1997 and that certain First Amendment dated as of September 15,
1997, (hereinafter, collectively the "Lease") for the leasing of certain
premises consisting of approximately 4,790 rentable square feet located at 1378
Willow Road, Menlo Park, California (the "Original Premises") as such Original
Premises are more fully described in the Lease,


B.   Landlord and Tenant now wish to amend the Lease to provide for, among other
things, the addition of certain space to the Original Premises, all upon and
subject to each of the terms, conditions, and provisions set forth herein.


NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt and adequacy of which are hereby
acknowledged, Landlord and Tenant agree as follows:


     1.  Recitals: Landlord and Tenant agree that the above recitals are true
         ---------                                                           
         and correct and are hereby incorporated herein as though set forth in
         full.


     2.  Premises:
         ---------
             2.1   Commencing on January 17 1998 (the "AP Commencement Date")
         there shall be added to the Original Premises those certain premises
         consisting of approximately 12,214 rentable square feet located at 1370
         Willow Road, Suite 200 (the "Additional Premises"), which Additional
         Premises are depicted on the site plan (building plan, etc.) attached
         hereto and made a part hereof as Exhibit A. Tenant hereby acknowledges
         that the Additional Premises are presently being occupied by Four 11
         Corporation (the "Existing Tenant").  Landlord's delivery to Tenant of
         possession of the Additional Premises by January 17, 1998 is contingent
         upon the Existing Tenant vacating the Additional Premises and
         surrendering possession thereof to Landlord by January 9, 1998.  If
         Landlord cannot deliver to Tenant possession of the Additional Premises
         broom clean but without any tenant improvements of any kind or nature
         on January 17, 1998, Landlord shall neither be subject to any liability
         nor shall the validity of the Lease be affected; provided, the Lease
         Term applicable to the Additional Premises shall commence on the date
         possession is tendered and in no event shall the Expiration Date be
         extended.  Accordingly, the date Landlord is to deliver the Additional
         Premises, namely 

                                                                  Please Initial

         January 17, 1998, shall only be extended to a date later than January
         17, 1998 if Landlord fails to tender to Tenant possession of the
         Additional Premises broom clean but without any tenant improvements of
         any kind or nature being made thereto solely due to the Existing Tenant
         failing to vacate and surrender possession of the Additional Premises
         to Landlord prior to January 9, 1997. Upon Landlord's delivery to
         Tenant of possession of the Additional Premises broom clean but without
         any tenant improvements being made there to of any kind or nature,
         Tenant shall promptly deliver written notice to Landlord confirming
         same (however, any failure by Tenant to deliver to Landlord such
         written notice shall not affect the effectiveness of the Lease). By
         taking possession of the Additional Premises broom clean without any
         tenant improvements of any kind or nature being made thereto, Tenant
         shall be deemed to have accepted the Additional Premises in good
         condition and state of repair.

             2.2    For purposes of the Lease, from and after the AP
         Commencement Date, the "Premises" as defined in Section I of the Lease
         shall mean and refer to the aggregate of the Original Premises and the
         Additional Premises consisting of a combined total of approximately
         17,004 rentable square feet located at 1370 Willow Road, Suite 200 and
         1378 Willow Road.  Accordingly, from and after the AP Commencement
         Date, all references in this Amendment and in the Lease to the term
         "Premises" shall mean and refer to the Original Premises and the
         Additional Premises.  Landlord and Tenant hereby agree that for
         purposes of the Lease, from and after the AP Commencement Date, the
         rentable square footage area of the Premises shall be conclusively
         deemed to be 17,004 rentable square feet.  In addition to the
         foregoing, it is the parties express intention that the balance of the
         Term of the Lease for the Original Premises and the Additional Premises
         be coterminous with the Expiration Date of the initial Term as
         specified in the Lease and that any option or renewal term described in
         the Lease shall be applicable to both the Premises and the Additional
         Premises.

             2.3   Notwithstanding anything to the contrary contained herein or
         in the Lease, Landlord shall neither be subject to any liability, nor
         shall the validity of the Lease be affected if Landlord is not able to
         deliver to Tenant possession of the Additional Premises by the AP
         Commencement Date.  Provided, however, Tenant's obligation to pay Rent
         on the Additional Premises shall commence on the date possession is
         tendered.

     3.  Base Rent: The Basic Lease Information and Section 3 of the Lease are
         ----------                                                           
         hereby modified to provide that during the Term of the Lease the

         provisions of Section 3 of the Lease shall be as follows:
