Exhibit 10.47    

SIXTH AMENDMENT TO INDUSTRIAL LEASE

THIS SIXTH AMENDMENT TO INDUSTRIAL LEASE AGREEMENT, (“the Amendment”) is made
and effective as of October 1, 2014, by and between the Economic Development
Authority of Montgomery County, Virginia, (“Landlord”), formerly known as the
Industrial Development Authority of Montgomery County a public body corporate,
having a principal place of business at 755 Roanoke Street, Suite 2H,
Christiansburg, Virginia 24073 and Luna Innovations Incorporated (“Tenant”), a
Virginia corporation having a principal place of business at 1 Riverside Circle,
Suite 400, Roanoke, Virginia 24016.
1.Introduction. Landlord and Tenant previously entered into that certain
Industrial Lease Agreement dated as of the 21st day of March, 2006, as amended
by the First Amendment dated effective as of May 11, 2006, as amended by the
Second Amendment (the “Second Amendment”) dated effective July 15, 2009, as
amended by Third Amendment (the “Third Amendment”) dated effective March 23,
2010, as amended by Fourth Amendment (the “Fourth Amendment”) dated effective
March 1, 2011, and as amended by Fifth Amendment (the “Fifth Amendment”) dated
effective as of November 1, 2011, (as amended, “the Lease”). Any capitalized
terms used but not defined herein shall have the meanings given to them in the
Lease. Landlord and Tenant have also signed a non-binding Letter of Intent dated
September 10, 2014, in respect of the Premises and the lease of new, replacement
space in the Building. Accordingly, effective as of the date hereof, Landlord
and Tenant have entered into an Industrial Lease Agreement for such replacement
space (the “New Lease”). Section 1.1 of the Lease incorporates Exhibit A in the
Lease clarifying the square footage in the Premises. The Parties wish to amend
Section 1.1 by incorporating a revised Exhibit A detailing Spaces A, B and C
which contains the current square footage being leased by the Tenant under the
Lease. The Tenant agrees to vacate and surrender Spaces A and B to the Landlord
prior to the termination of the Lease. Landlord agrees to amend Section 1.2 by
extending the term of the Lease allowing Tenant to remain in Space C from
November 30, 2014, through January 3, 2015. Section 3.1.1 of the Lease provides
for a base rent of $39,125 per month for the Premises. This base rent shall be
reduced proportionately for the month of October based on the Tenant vacating
Spaces A by or on October 14, 2014, and no rent shall be charged Tenant to lease
Space B from November 1, 2014 through November 16, 2014, and Space C from
November 1, 2014 through January 3, 2015.
NOW THEREFORE, in consideration of the rents, covenants, and agreements set
forth herein, and in the Lease and for other good and valuable consideration,
the receipt and sufficiency of which is hereby acknowledged, the Parties hereby
agree to the following terms:
2.Premises. The Tenant agrees that Space A, as shown on Exhibit A which is
attached and incorporated into this Amendment (“Exhibit A”) shall no longer be
part of the Leased Premises as of October 15, 2014. The Tenant agrees to vacate
and surrender Space A to the Landlord by October 15, 2014. The Tenant agrees
that Space B as shown on Exhibit A shall no longer be part of the Leased
Premises as of November 16, 2014. The Tenant agrees to vacate and surrender
Space B to the Landlord by November 16, 2014. Exhibit A attached to the Lease is
replaced with Exhibit A attached hereto.

3.Term. The Term of the Lease under Section 1.2 shall be extended from November
30, 2014 until January 3, 2015 for the Tenant’s use of Space C as shown on
Exhibit A. Notwithstanding anything else to the contrary, in the event the
Premises under the New Lease are not ready for the Tenant to move into and
occupy for their intended purpose due to a delay in Renovations and has not
received a Certificate of Occupancy for such Premises (as such terms are defined
in the New Lease), then Tenant may remain in Space C rent-free until such
renovations are complete enough for the move.

4.Payment of Rent. The payment of rent under Section 3.1.1 of the Lease shall be
reduced proportionately in October based on the reduction in square footage of
the Premises after the Tenant vacates and surrenders Space A by or on October
14, 2014, which reduces the monthly base rent for October from $39,125 to
$36,492 a reduction of $2633. The Tenant shall have use of Space B rent free
from November 1, 2014 through November 16, 2014. The Tenant shall have use of
Space C rent free from November 1, 2014 through January 3, 2015.

5.Miscellaneous. The terms and conditions set forth in the Introduction are
incorporated herein by reference. This Amendment may be executed in any number
of identical counterparts and, as so executed, shall constitute one agreement,
binding on all the parties hereto, notwithstanding that all the parties are not
signatories to the original or the same counterpart.

6.Except as specifically amended herein, the Lease shall remain in full force
and effect.

In Witness Whereof, Landlord and Tenant have executed this Sixth Amendment as of
the date set forth hereinabove.
