                            FIRST AMENDMENT TO LEASE


         THIS FIRST AMENDMENT TO LEASE ("First Amendment") is made and entered
into as of May 1, 1995, by and between IRISH LEASING CORPORATION, a Texas
corporation ("Landlord"), and CISCO SYSTEMS, INC., a California corporation
("Tenant").

         THIS FIRST AMENDMENT IS ENTERED INTO upon the basis of the following
facts, understandings and intentions.

         A.      Landlord and Tenant entered into that certain Lease dated
February 28, 1995 ("Lease"), pursuant to which Landlord is leasing to Tenant
that certain land located in San Jose, California, as more particularly
described in the Lease and on Exhibit A attached hereto and incorporated herein
by this reference ("Premises").  Any capitalized terms used but not defined in
this First Amendment which are defined in the Lease shall have the meaning
ascribed in the Lease.

         B.      Landlord and Tenant now desire to amend the terms of the
Lease, as more particularly described in this First Amendment.

         NOW, THEREFORE, in consideration of the mutual covenants herein
contained, the parties hereby agree as follows:

         1.      Equity Funded Amount.  Section 2.10 is hereby deleted, and is
                 replaced with the following:

                 2.10     Equity Funded Amount.  "Equity Funded Amount" shall
                 mean that portion of the Funded Amount equal to the Funded
                 Amount minus the Senior Funded Amount and which shall be an
                 amount equal to fifteen percent (15%) of the Funded Amount.

         2.      Lease Rate.  Section 2.23 is hereby deleted, and is replaced
                 with the following:

                 2.23     Lease Rate.  "Lease Rate" shall mean interest at the
                 rate of the product of 0.850 times the then-effective LIBOR
                 Rate, plus .0045, per annum.

         3.      Lease Rate.  Section 2.26 is hereby deleted, and is replaced
                 with the following:

                 2.26     LIBOR Rate.  "LIBOR Rate" shall mean the LIBOR
                 interest rate as defined in that certain Schedule I,
                 Additional Terms and Conditions of Credit Arrangement between
                 SGA and UBS dated May 1, 1995, relating to the UBS Loan
                 ("Schedule I"), or as defined in a subsequent Authorized Loan.

         4.      Interest Rate Selection.  Section 5.1(b) is hereby deleted,
                 and is replaced with the following:

                 (b)      Interest Rate Selection.  The parties acknowledge
                 that the interest rate applicable under the UBS Loan (or other
                 Authorized Loan) shall affect the amount of Base Rent payable
                 by Tenant hereunder.  Therefore, Tenant shall have the right,
                 by written notice to UBS (or the holder of any Authorized
                 Loan), SGA and Landlord, to designate the interest period to
                 be selected from time to time by SGA pursuant to Schedule I
                 (or other Authorized Loan).  Tenant acknowledges that the
                 rates available to be selected under the UBS Loan after the
                 first partial calendar month of the Term are 1, 2, 3, 6, 9 or
                 12-month LIBOR rates.  In the event that Tenant fails to give
                 such written notice to UBS (or other holder of an Authorized
                 Loan), SGA and Landlord prior to the applicable deadline for
                 selection of such interest period pursuant to the

   2
                 terms of Schedule I (or other Authorized Loan), Tenant shall be
                 deemed to have selected an interest period of one month for the
                 UBS Loan (or other Authorized Loan).

         5.      Further Mortgages or Encumbrances by Landlord.

         The first sentence of Article 13, Section 13.1, subparagraph (b)
Authorized Loan that begins with "Tenant has approved . . ." and ends with ". .
all documents related to the UBS Loan" is hereby deleted and replaced with the
following:

                 Tenant has approved the terms of the loan ("UBS Loan") to be
                 made by UBS to SGA which shall be evidenced by that certain
                 Tranche B Promissory Note dated as of the Lease Commencement
                 Date by SGA in favor of UBS ("UBS Note"), and further
                 evidenced and/or secured by (a) that certain General Terms and
                 Conditions of Credit Arrangement between SGA and UBS, (b) that

                 Arrangements between SGA and UBS, (c) that certain Pledge
                 Agreement, as amended by Rider No. 1 thereto, made by Tenant
                 in favor of UBS, and (d) certain documents (including, without
                 limitation a promissory note and related documents) evidencing
                 a loan ("SGA Loan") from SGA to Landlord in the principal
                 amount of the UBS Note, all dated as of the Lease Commencement
                 Date; provided, however, that Tenant, Landlord and SGA reserve
                 the right to approve, in their sole discretion, the final form
                 of all documents related to the UBS Loan.

         6.      Option to Purchase Premises.  (a)  In Section 19.1(a),

("Purchase Price") . . ." on line 8 of Section 19.1(a) and ending with ". . .

entirety and the following inserted in their place:

                 The purchase price ("Purchase Price") for the portion of the
                 Premises which Tenant elects to purchase shall be (i) the
                 then-existing Funded Amount applicable to the portion of the
                 Premises which Tenant elects to purchase (determined in a pro
                 rata basis on the basis of the area being purchased), as the
                 same may be reduced from time to time, plus (ii) the amount of
                 any prepayment premium and all other fees, costs, and expenses
                 due to any holder of an Authorized Loan in connection with
                 such loan (to the extent not already paid pursuant to Section
                 21.21 hereof).  Tenant shall be entitled to a credit against
                 the Purchase Price in an amount equal to the sum of (i) the
                 principal balance(s) of any Authorized Loan and/or Fee
                 Mortgage existing immediately prior to the closing under this

                 Option, Landlord shall be released from Landlord's obligation
                 to return the Security Deposit set forth in Section 5.5
                 hereof.
