THIS THIRD AMENDMENT TO THE STRATEGIC ALLIANCE AGREEMENT (this “Amendment”) made
as of December 29, 2005, between GIGABEAM CORPORATION, a Delaware corporation
(the “Company”), having its principal executive office at 470 Springpark Place,
Suite 900, Herndon, VA 20170 and THINKOM SOLUTIONS, INC., a California
corporation (“ThinKom”), having its principal executive offices at 3825 Del Amo
Blvd, Suite 200, Torrance, CA 90503.
 
W I T N E S S E T H
 
WHEREAS, the Company and ThinKom entered into a certain Strategic Alliance
Agreement dated January 5, 2004 (the “Agreement”), as amended, whereby the
Company would design, manufacture and market a commercial point-to-point
terrestrial wireless communications system utilizing a frequency range of 71
GigaHertz (“GHz”) through 76 GHz and 81 GHz through 86 GHz which incorporates
ThinKom’s antenna component technologies;

WHEREAS, the Company and ThinKom desire to further amend certain of the terms
and provisions of the Agreement,

NOW, THEREFORE, in consideration of the mutual covenants made herein and other
good and valuable consideration, receipt of which is hereby acknowledged, the
Company and ThinKom hereby agree as follows:

SECTION 1. Amendments to the Agreement. Effective as of the date hereof:

 
A.
Exhibit D to the Agreement, as amended, shall be deleted in its entirety and
replaced with the Further Amended Exhibit D (the “Further Amended Exhibit D”),
attached hereto as Appendix A.

 
B.
Change last two lines of Section 13 of the Agreement to read “last calendar
quarter of year 2007” rather than “last calendar quarter of year 2006”. This
will delay the ThinKom pay back of working capital advanced by Gigabeam to
ThinKom, consistent with the delay of Minimum Purchases by Gigabeam from ThinKom
as shown in Appendix A attached hereto.

SECTION 2. Representation and Warranties. The Company and ThinKom hereby
represent and warrant as follows (with the effectiveness of this Amendment being
further conditioned upon all such representations and warranties being true and
correct in all material respects on the date of this Amendment):

 
(a)
The execution, delivery and performance by the Company and ThinKom of this
Amendment has been duly authorized by all necessary corporate action;

 
(b)
This Amendment to which the Company and ThinKom is a party constitute legal,
value and binding obligations of the Company and ThinKom, respectively,
enforceable against it in accordance with their respective terms, except to the
extent that such enforcement may be limited by applicable bankruptcy,
insolvency, equitable remedies and other similar laws affecting creditors’
rights generally, and except that the availability of equitable remedies is
subject to the discretion of the court before which such remedies are sought:

 

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

 

 
(c)
No event has occurred and is continuing which has not been waived which
constitutes a breach of the Agreement.

SECTION 3. Effect on the Agreement. Except as specifically amended hereby, the
Agreement shall continue to be in full force and effect and is hereby in all
respects ratified and confirmed.

SECTION 4. Execution of Counterparts. This Amendment may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed to be an original
and all of which taken together shall constituted but one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Amendment by telecopier of facsimile shall be effective as delivery of a
manually executed counterpart of this Amendment.

IN WITNESS WHEREOF, the parties have caused this Amendment to be duly executed
on their behalf in their respective corporate names by their duly authorized
officers all as of the date first above written.
