Exhibit 10.19

FIRST AMENDMENT TO SINGLE-TENANT LEASE

This FIRST AMENDMENT TO SINGLE-TENANT LEASE ("Amendment") dated for reference
purposes only as of December 10, 2013, is entered into by and between GCCFC
2007-GG9 DIAMOND OFFICE LIMITED PARTNERSHIP, a Delaware limited partnership
("Landlord"), successor-in-interest to La Palma Flex, L.P. ("Original
Landlord"), and A.J.OSTER WEST, LLC, a Delaware limited liability company
("Tenant").

RECITALS:

A.     Landlord (as successor-in-interest to Original Landlord) and Tenant are
parties to that certain Single-Tenant Lease dated as of February 1, 2009 (the
"Lease"), pursuant to which Tenant currently leases from Landlord those certain
premises containing approximately 50,282 rentable square feet consisting of the
entire building commonly known as 22833 La Palma Avenue, Yorba Linda, California
(the "Premises"), as more particularly described in the Lease. Landlord has
succeeded to all of the rights and interests of Original Landlord as "landlord"
under the Lease.

B.     Capitalized terms which are used in this Amendment without definition
have the meanings given to them in the Lease.

C.     The current Term (the "Existing Term") of the Lease is scheduled to
expire on March 31, 2014. Landlord and Tenant desire to amend the Lease to: (a)
adjust the terms of the Lease retroactively as of March 1, 2014, (b) extend the
Existing Term and (c) further amend other terms of the Lease as hereinafter set
forth.

AGREEMENT:

NOW, THEREFORE, in consideration of the foregoing Recitals, the mutual covenants
and agreements contained in this Amendment and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
Landlord and Tenant hereby agree as follows:

1.     Extension. The Existing Term, which is currently scheduled to expire on
March 31, 2014, is hereby extended to expire on October 31, 2019 (the "New Term
Expiration Date"), unless sooner terminated as provided in the Lease, as hereby
amended (the "Amended Lease"). The sixty-eight (68) month period commencing as
of March 1, 2014 (the "New Term Commencement Date") through and including the
New Term Expiration Date shall be referred to herein as the "New Term". No such
extension shall operate to release Tenant from liability for any amounts owed or
defaults which exist under the Amended Lease.

2.     Monthly Rent.

(a)     Existing Term Monthly Rent. Subject to the terms of this Section 2(a)
and provided Tenant is not and has not, during the duration of the Existing Term
or the New

1

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

Term, been in default under the terms of the Amended Lease, Landlord agrees to
abate Tenant's obligation to pay Monthly Rent for the months of December 2013
through April 2014, inclusive (the "Abatement Months"). Such amount of abated
Monthly Rent in the total amount of $151,850.20 is hereafter referred to as the
"Abated Amount". During the Abatement Months, Tenant will still be responsible
for the payment of all other monetary obligations under the Amended Lease
without reduction or abatement. Tenant acknowledges that any default by Tenant
under the Amended Lease will cause Landlord to incur costs not contemplated
hereunder, the exact amount of such costs being difficult and impracticable to
ascertain. Therefore, should Tenant at any time during the Existing Term or New
Term be in default after having been given notice and opportunity to cure, then
the total unamortized sum of such Abated Amount (amortized on a straight line
basis over the New Term) so conditionally excused shall become immediately due
and payable by Tenant to Landlord and any remaining Abated Amount shall no
longer be available to Tenant as a rent credit from the date of such default.
Tenant acknowledges and agrees that nothing in this Section 2(a) is intended to
limit any other remedies available to Landlord at law or in equity (including,
without limitation, the remedies under Civil Code Section 1951.2 and/or 1951.4
and any successor statutes or similar laws), in the event Tenant defaults under
the Amended Lease beyond any applicable notice and cure period. Except as
otherwise set forth herein with respect to the Abated Amount, prior to the New
Term Commencement Date, Tenant shall continue to pay Monthly Rent for the
Premises pursuant to the terms of the Lease.

(b)     New Term Monthly Rent. Commencing as of the New Term Commencement Date
and continuing for the duration of the New Term, Tenant shall pay Monthly Rent
for the Premises according to the following schedule:
New Term 
Monthly Rent
3/1/14 - 2/28/15
$27,655.10
3/1/15 - 2/29/16
$28,484.75
3/1/16 - 2/28/17
$29,339.29
3/1/17 - 2/28/18
$30,219.47
3/1/18 - 2/28/19
$31,126.05
3/1/19 - 10/31/19
$32,059.83

All such Monthly Rent shall be payable by Tenant to Landlord in accordance with
the terms of the Amended Lease.

3.     Condition of Premises.

(a)     Allowance. So long as Tenant is not in default under the Amended Lease,
commencing as of the mutual execution of this Amendment ("Allowance Availability
Date"), Landlord shall make available to Tenant an allowance of up to One
Hundred Thousand and No/100ths Dollars ($100,000.00) (the "Allowance") which
shall be used by Tenant to pay for costs of completing refurbishments (the
"Refurbishment Work") to

2

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

the Premises subject to Landlord's prior written approval and Tenant's
compliance with the terms and conditions of the Lease, including, without
limitation, Sections 12 and 13.1 thereof. Landlord shall pay Tenant the lesser
of the actual cost of the Refurbishment Work or the Allowance within thirty (30)
days after Tenant submits to Landlord copies of any and all contracts, receipts,
and lien waivers or releases, evidencing: (a) the costs incurred by Tenant for
the Refurbishment Work, (b) the costs which have been paid in full by Tenant,
and (c) the absence of any liens from any person or entity performing work
and/or providing services and/or supplies in connection with the Refurbishment
Work. Notwithstanding the foregoing, if Tenant has not substantially completed
the Refurbishment Work and requested payment of the applicable portion of the
Allowance by the last day of the twelfth (12th) calendar month following the
Allowance Availability Date, Tenant's right and interest in and to the
Allowance, and Landlord's obligation to pay the Allowance to Tenant, shall be
null and void and of no further force or effect. Except for the Allowance and
the Roof Work as provided in Section 3(b) below, Landlord shall not be obligated
to refurbish or improve the Premises in any manner whatsoever or to otherwise
provide funds for the improvement of the Premises in conjunction with the New
Term, and Tenant hereby accepts the Premises in its current "AS-IS" and
"WHERE-IS" condition. Tenant further acknowledges that except as expressly
provided in this Amendment, neither Landlord nor any agent of Landlord has made
any representation or warranty regarding the condition of the Premises, the
improvements, refurbishments, or alterations therein, if any, or the Property,
or with respect to the functionality thereof or the suitability of any of the
foregoing for the conduct of Tenant's business.

(b) Roof Work. Landlord shall replace, when Landlord deems necessary, the roof
of the Premises, including the roof membrane (the "Roof Work") according to
plans and specifications and using materials selected by Landlord at Landlord's
sole cost and expense. The Roof Work will be conducted in the Premises while
Tenant is in occupancy thereof and paying rent under the Amended Lease. Tenant
agrees to cooperate with Landlord and to make the Premises reasonably available
to Landlord and its contractors for the performance of the Roof Work. Tenant
acknowledges that some interruptions and/or interference with Tenant's business
may occur during the course of the Roof Work, but agrees that no interruptions
or inconveniences to Tenant or its business suffered as a result of the Roof
Work shall constitute an eviction of Tenant from the Premises, whether
constructive or otherwise, and Tenant shall in no event be excused from paying
the Monthly Rent and/or additional rent that it is scheduled to pay pursuant to
the terms of the Amended Lease. Landlord may or may not perform the Roof Work
during normal business hours. If Tenant requires that the Roof Work be performed
after Tenant's business hours, Tenant shall pay to Landlord the additional
costs, if any, to perform the Roof Work after business hours. Landlord and
Tenant shall cooperate and cause their respective employees, agents and
contractors to cooperate with the other during said period to expedite
completion of the Roof Work as well as to minimize any interference with
Tenant's business operations in the Premises. Such cooperation by Tenant shall
include, without limitation, moving, packing, and/or other temporary relocation
of furniture and fixtures within the Premises at Tenant's expense. Landlord
shall use commercially reasonable efforts to complete the Roof Work according to
the schedule attached hereto as Exhibit "A" (the "Schedule"), subject to
extension for any

3

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

delay beyond the reasonable control of Landlord and/or any Tenant-related
delays; provided, however, Tenant acknowledges and agrees that the dates in the
Schedule are estimates, and that Landlord shall not be deemed in default under
the Amended Lease, nor shall Tenant be entitled to any damages and/or any
abatement of rent, if Landlord does not complete the Roof Work according to the
Schedule.

4.     Roof Membrane. Notwithstanding the terms of the Lease to the contrary
(including Sections 11.1 and 11.2 thereof), during the New Term, Landlord shall
repair and replace, as necessary, the roof membrane of the Premises at
Landlord's sole cost; provided, however, to the extent any repair and/or
replacement is required as a result of any act, neglect, fault or omission of
Tenant or any of Tenant's Parties or otherwise made necessary due to Tenant's
specific use (as opposed to general occupancy of the Premises) or Tenant's
Changes to the Premises, Tenant shall pay to Landlord within thirty (30) days of
receipt by Tenant of written demand from Landlord, as additional rent, the costs
of such repair and/or replacement, together with a reasonable management fee.
Tenant shall continue to be responsible for the maintenance of the roof membrane
pursuant to the terms of the Lease.

5.     Capital Items. Notwithstanding the terms of the Lease to the contrary
(including Section 11.3 thereof), during the New Term, Landlord shall be
responsible for any and all capital repairs or capital replacements to the
Premises; provided, however, to the extent such repairs or replacements are
required as a result of any act, neglect, fault or omission of Tenant or any of
Tenant's Parties or otherwise made necessary due to Tenant's specific use (as
opposed to general occupancy of the Premises) or Tenant's Changes to the
Premises, Tenant shall pay to Landlord within thirty (30) days of receipt by
Tenant of written demand from Landlord, as additional rent, the costs of such
repairs or replacements, together with a reasonable management fee. Tenant shall
continue to maintain, at Tenant's cost, contracts (pre-approved by Landlord,
which approval shall not be unreasonably withheld), with respect to the HVAC and
HVAC systems in the Premises pursuant to the terms of the Lease. Except as
otherwise expressly provided in this Amendment, Landlord and Tenant shall
continue to have the maintenance, repair and replacement obligations as provided
under the Lease.

6.     Tenant's Changes. Tenant shall be responsible for the cost of any and all
upgrades to the Property required by Law (including, without limitation,
Americans With Disabilities Act) relating to, or made necessary in connection
with, the Roof Work and/or Tenant's Changes.

7.     Options.

(a)     Extension Option.     During the New Term, Tenant shall continue to have
the Extension Option described in Section 2.3 of the Lease; provided, however,
Section 2.3 is hereby amended as follows: (i) all references to "Term" shall
mean and refer to the New Term, (ii) all references to "Lease" shall mean and
refer to the Amended Lease, (iii) the Option Term shall be for five (5) years,
(iv) Tenant shall exercise its Extension Option, if at all, no later than six
(6) months prior to the expiration of the New Term and (v) the Monthly Rent
during the Option Term shall be the greater of the Fair Market Rental Rate or
103% of the Monthly Rent applicable during the last month of the New Term. The
Extension Option may be exercised only by the original Tenant while

4

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

occupying and leasing the entire Premises and without having assigned the
Amended Lease or sublet any portion of the Premises.

(b)     Termination Option.     Tenant will have the one-time option to
terminate and cancel the Amended Lease ("Termination Option"), effective as of
11:59 p.m. on the last day of the forty-third (43rd) full calendar month of the
New Term ("Termination Date"), by delivering to Landlord, on or before the date
which is six (6) months prior to the Termination Date, written notice of
Tenant's exercise of its Termination Option. As a condition to the effectiveness
of Tenant's exercise of its Termination Option and in addition to Tenant's
obligation to satisfy all other monetary and non-monetary obligations arising
under the Amended Lease through to the Termination Date, Tenant shall pay to
Landlord the then unamortized value (amortized on a straight line basis over the
New Term, with interest thereon at the Interest Rate) of the following
(collectively, the "Termination Consideration"): (i) the Allowance and the cost
of any leasehold improvements made by Landlord at Landlord's expense for the
benefit of Tenant, (ii) the Abated Amount, and (iii) brokerage commissions paid
by Landlord in connection with this Amendment. The Termination Consideration
shall be due and payable by Tenant to Landlord in two equal installments:
one-half (1/2) of the Termination Consideration to be delivered concurrently
with Tenant's delivery of notice to Landlord of the exercise of the Termination
Option, and the remaining one-half (1/2) of the Termination Consideration to be
delivered on the first day of the month preceding the Termination Date (the
"Final Payment"). If Tenant properly and timely exercises its Termination Option
and properly and timely delivers the Termination Consideration to Landlord as
set forth above and satisfies all other monetary and non-monetary obligations
under the Amended Lease including, without limitation, the provisions regarding
surrender of the Premises, all of which must be accomplished on or before the
Termination Date, then the Amended Lease will terminate as of midnight on the
Termination Date; provided, however, if Tenant fails to deliver the Final
Payment on the first day of the month preceding the Termination Date, Tenant's
Termination Option shall be deemed null, void and of no force or effect and the
Amended Lease shall continue in full force and effect notwithstanding Tenant's
exercise of its Termination Option. The Termination Option is personal to the
original Tenant executing this Amendment and may be exercised only by the
original Tenant executing this Amendment while occupying and leasing the entire
Premises and without having assigned the Amended Lease or sublet any portion of
the Premises.

(c) No Further Options.     Tenant acknowledges and agrees that except as
expressly provided herein with respect to the Abated Amount, Allowance, the
Extension Option and Termination Option referenced in Sections 2(a), 3, 7(a) and
7(b) above, Tenant has no further tenant improvement allowances, rent
abatements, other concessions and/or any options, including, without limitation,
any option to further extend the New Term or terminate the New Term early, any
right of first offer and/or any right of first refusal to lease or purchase.
Accordingly, Sections 12.5 (Refurbishment Allowance) and 2.2 (Termination
Option) of the Lease are hereby deleted in their entirety and are deemed null,
void and of no further force or effect.

8.     California Accessibility Disclosure.     For purposes of Section 1938 of
the California Civil Code, Landlord hereby discloses to Tenant, and Tenant
hereby acknowledges,

5

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