This SECOND AMENDMENT TO SUBLEASE (this "Second Amendment") is made and entered
into as of the 31st day of January, 2001, by and between GRC INTERNATIONAL, INC.
(the "Sublessor") and SOMERA COMMUNICATIONS, INC. (the "Sublessee").

                                R E C I T A L S:

A. On or about January 30, 1998, Sublessor and Sublessee entered into that
certain Sublease (the "Original Sublease"), whereby Sublessor subleased to
Sublessee and Sublessee subleased from Sublessor approximately 10,859 rentable
square feet (approximately 9,826 usable square feet) (the "Original Premises")
on the first and second floors of the project located at 5383 Hollister Avenue,
Santa Barbara, California (the "Property"). The Original Premises consisted of
Suite A (approximately 8,263 rentable square feet on the first floor), Suite B
(approximately 1,535 rentable square feet on the second floor), and Suite C
(approximately 1,061 rentable square feet on the second floor).

B. On or about November 18, 1999, Sublessor and Sublessee entered into that
certain First Amendment to Sublease (the "First Amendment") pursuant to which
Sublessor and Sublessee, among other things, (i) expanded the Original Premises
to include an additional approximately 3,346 rentable square feet (Suite D) (the
"First Expansion Space") on the second floor of the Property, and (ii) as a
result of the addition of the First Expansion Space, (x) increased "Sublessee's
Percentages", (y) increased Sublessee's annual rent, and (z) increased
Sublessee's security deposit. The Original Premises, together with the First
Expansion Space, are sometimes referred to herein collectively as the
"Premises."

C. Sublessor and Sublessee now desire to further modify and amend the Sublease
in accordance with the terms and conditions contained in this Second Amendment.
The Original Sublease and First Amendment are sometimes referred to herein
collectively as the "Sublease." Copies of both the Original Sublease and the
First Amendment are attached as Exhibit "A" to this Second Amendment and are
incorporated herein by this reference. Capitalized terms that are not defined in
this Second Amendment shall have the meanings ascribed to them in the Sublease.

                               A G R E E M E N T:

NOW, THEREFORE, incorporating and in consideration of the foregoing recitals,
and for other good and valuable consideration, the receipt and sufficiency of

1. Expansion of Premises. The Premises are hereby further expanded and increased
to include approximately 6,380 additional square feet of rentable area (Suite
210) (the "Second Expansion Space") on the second floor of the Property. The
Second Expansion Space has been previously subleased to Goleta National Bank
("GNB") and sub-subleased by GNB to Expertcity.com ("Expertcity"). The GNB
Sublease and the Expertcity Sub-Sublease (as such terms are defined in Section 2
hereinbelow) shall terminate concurrently with the Effective Date (as that term
is defined in Section 9 hereinbelow) of this Second Amendment. The location of
the Second Expansion Space in the Property is illustrated on Exhibit "B" to this
Second Amendment, which Exhibit "B" is attached hereto and incorporated herein
by this reference. Accordingly, upon the Effective Date, the Premises shall
include approximately 20,585 square feet of rentable area in the Property, which
Premises shall consist of the Original Premises, the First Expansion Space and
the Second Expansion Space.

2. Sublessor Representation. Sublessor hereby represents and warrants to

Effective Date hereof.

3. Increase in Initial Annual Rental. Prior to the Effective Date of this Second
Amendment, Sublessee's Initial Annual Rental obligation for the Premises was
$229,268.76 (which corresponded to a Base Monthly Rental Obligation of
$19,105.73). Following the Effective Date, with the expansion of the Premises to
include the Second Expansion Space, the Sublessee's Initial Annual Rental shall
be increased to $336,348.12 (with the Base Monthly Rental Obligation to be
correspondingly increased to $28,029.01).

Expansion Space on the Effective Date. The Second Expansion Space is currently
unoccupied and in broom clean condition. Sublessor hereby represents and
warrants to Sublessee that Sublessor will not modify nor permit any other party
to modify the Second Expansion Space in any manner from the date hereof through

on the Effective Date as the date hereof, Sublessee shall accept the Second
Expansion Space in its "As-Is" condition on the Effective Date.

6. Construction of Sublessee Improvements to the Second Expansion Space.
Sublessee shall be solely responsible for all costs and expenses incurred in
connection with the design, layout and construction of any and all improvements
to the Second Expansion Space (collectively, the "Improvements").
Notwithstanding the preceding, Sublessee may not commence construction of any
Improvements to the Second Expansion Space which are structural in nature
without (a) providing the Master Landlord and Sublessor with all plans and
specifications related to any such proposed structural Improvements, and (b)
receiving the Master Landlord's and Sublessor's prior written consent to such
structural Improvement plans and specifications, which approval shall not be
unreasonably withheld, conditioned or delayed.

7. Option to Extend. The Sublessee's Options to Extend (as set forth in the
Original Sublease) shall be effective for the Second Expansion Space.

8. Right To Cancel. Pursuant to the Original Sublease, the Sublessee has the
Right to Cancel the Sublease at anytime after April 1, 2001 by providing the
Sublessor with at least 180 days advance written notice of Sublessee's election
to so terminate the Sublease. Such Right to Cancel shall not apply to the Second
Expansion Space.

9. Effective Date; Termination Date. This Second Amendment shall not be
effective (and, accordingly, none of Sublessor's or Sublessee's obligations

Security Deposit for the Premises from $18,888.55 to $27,811.83. Accordingly, on
the Effective Date, Sublessee shall forward to Sublessor a check equal to
exactly $8,923.28 in order to increase the Security Deposit as provided herein.

11. Additional Consideration to be Paid to Sublessor. As additional
consideration to Sublessor for Sublessor's agreement to permit Sublessee to
expand the Premises to include the Second Expansion Space in accordance with the
terms and conditions of the Second Amendment, Sublessee hereby agrees to pay to

unable to or fails to return all or any portion of the Approved Inventory to the
Second Expansion Space at the expiration or earlier termination of the Sublease,
Sublessor and Sublessee shall work together to determine the fair market value
of the unreturned Approved Inventory, and Sublessee shall promptly reimburse

                  of approximately $61,250 (at 100% of plan)(the "Bonus") paid

                  be based upon the achievement of the criteria specified by the
                  President and calculated for Fiscal Year 2001 only as follows:

                        >     20% of base salary if 90% to 99% of Plan is
                              achieved

                        >     35% of base salary if 100% to 114% of Plan is
                              achieved

                        >     50% of base salary if 115% to 129% of Plan is

                  make any bonus payments, whether during the first or any
                  subsequent period, should be dependent upon employee's
                  employment with the company throughout the end of each payment
                  period. For purposes of the Bonus, the annual period shall
                  commence on the Commencement Date (or anniversary thereof) and
                  continue for a one-year period. Employee will participate in
                  the final establishment of the Fiscal Year 2001 revenue and
                  profit targets upon which the above bonus incentive is based
                  as well as all moving forward targets and bonus based criteria

      (c)   Equity Compensation

            (i)   Stock Option

                  It will be recommended at the first meeting of the Company's
                  Board of Directors following your start date that the Company
                  grant you an option to purchase 220,000 shares of the
                  Company's Common Stock at a price per share equal to the fair
                  market value per share of the Common Stock on the date of
                  grant, as determined by the Company's Board of Directors. This
                  option grant shall be subject to the terms and conditions of
                  the Company's Stock Option Plan and Stock Option Agreement,
                  including vesting requirements. The option shall be for a term
                  of ten years (or shorter upon termination of employment or
                  consulting relationship with the Company) and, subject to
                  accelerated vesting as set forth below, shall be vested with
                  respect to twenty-five percent (25%) as of the first
                  anniversary of your date of employment and shall thereafter
                  vest at the rate of 1/36th of the remaining seventy-five
                  percent (75%) on the first day of each month following the
                  first anniversary of your date of employment.

                  In addition, in the event of (i) a Change in Control (as
                  defined below), and if, on or subsequent to the closing date
                  of the transaction(s) giving rise to such
<PAGE>

                  Change in Control you are terminated without Cause or are
                  Constructively Terminated, then the 25% of shares that are
                  then unvested, if any, shall vest automatically immediately on
                  the date that your employment with the Company (or its
                  successors) is terminated in addition to being paid the
                  Severance terms as outlined below.

                  stock or all or substantially all of the assets of the Company
                  where, in any such event, the shareholders of the Company
                  immediately preceding such transaction(s) do not hold at least
                  a majority of the voting stock of the entity surviving the
                  merger (in the case of clause (i)) or purchasing the assets or
                  stock (in the case of clause (ii)). Such vesting shall be
                  conditioned upon Employee's continued employment with the
                  Company as of each vesting date.

      (d)   Severance

            (i)   Termination Without Cause

                  In the event that the Employee's employment with the Company
                  is involuntarily terminated by the Company without "Cause" or
                  is "Constructively Terminated" (both as defined below), then
                  Employee shall receive a lump-sum payment equal to Four (4)
                  Months of his Base Salary. Further, Employee shall also
                  receive accelerated vesting of 25% of shares that are then
                  unvested within any period between the first (6) and Twelve
                  (12) months of service and then, thereafter, per the vesting
                  schedule as detailed above.

                  For the purposes of this Agreement, "Cause" is defined as: (i)

                  responsibilities as an employee of the Company, (ii)

                  breach or failure to perform his employment duties as

                  such breach within thirty (30) days after receipt of written
                  notice of breach from the Company.

                  For this purpose, "Constructive Termination" is defined as the
                  resignation of Employee within sixty (60) days following (i)

                  status as Vice President, or any material reduction of the
                  Employee's duties, authority, responsibilities or title,
                  relative to the Employee's duties, authority, responsibilities
                  or title as in effect immediately prior to such reduction,
                  except if agreed to in writing by the Employee; (ii) a
                  material reduction by the Company in the Base Salary, as in

                  contract or whatever is most current at the time prior to the
                  reduction);or (iii) the relocation of the Employee to a
