ARTICLE 2A
EXPANSION OF DEMISED PREMISES

Section 2A.l  Expansion Improvements.

The
Expansion Improvements shall mean that additional bulk warehouse space and
dock facilities, if any, contiguous to the Initial Improvements and associated site work,
all of which shall be as depicted in Exhibit G attached hereto and made a part
hereof, which Landlord shall cause to be constructed on the Land, subject to finalization
and preparation of the Final Expansion Base Building Plans and Final Expansion Interior
Design Plans and Specifications (as such terms are defined in Section 2A.2 below), in
accordance with this Article 2A. Attached hereto and made part hereof as Exhibit G
are preliminary expansion plans and specifications for the Expansion Improvements
(Preliminary Expansion Plans and Specifications), consisting of outline
specifications prepared by McShane Construction Corporation dated October 18, 2005,
revised November 2, 2005, November 11, 2005 and further revised February 13, 2006; site
plan dated February 10, 2006; floor plan dated February 10, 2006 and Civil Drawings sheets
C0-C5 dated February 9, 2006. Tenant has reviewed and approved all of the Preliminary
Expansion Plans and Specifications. Tenant hereby authorizes and directs Landlord to
proceed with the preparation of the components of the Final Expansion Plans and
Specifications and the commencement of construction of the Expansion Improvements.

Section
2A.2 Preparation of Expansion Plans. On or before the date which is forty- five
(45) days after the date hereof and subject to Section 2A.8 hereof, Landlord shall cause
to be prepared and delivered to Tenant all of the components of the (i) base building
specifications for the Expansion Improvements (Final Expansion Base Building
Plans) and (ii) interior design specifications for the Expansion Improvements
(Final Expansion Interior Design Plans and Specifications); each of which
shall be prepared by Harris Architects, Inc. (Expansion Architect or
Architect), shall be based on the Preliminary Expansion Plans and
Specifications and shall be in a form sufficiently complete to enable the issuance of a
building permit by the City.

If
each component of the Final Expansion Base Building Plans and the Final Expansion Interior
Design Plans and Specifications, respectively, submitted by Landlord is in substantial
compliance with the Preliminary Expansion Plans and Specifications, then Tenant shall
neither unreasonably withhold its approval of any such submitted component (except for
just and reasonable cause) nor act in an arbitrary or capricious manner with respect to
the approval thereof; provided, further however, that it shall be unreasonable for Tenant
to withhold its approval of any submitted component if (i) the component (or any revision
thereto) is designed or necessary to meet any municipal or private business park
requirement or restriction; or (ii) the component is in substantial conformance with the
Preliminary Expansion Plans and Specifications. The procedure for the approval or
disapproval, revision and resubmission of the components of the Final Expansion Plans and
Specifications shall be the same as set forth in Section 2.2(c) hereof for the Final Plans
and Specifications for the Initial Improvements, except that Tenant will have ten (10) not
twenty (20) business days after Landlords initial delivery to Tenant of each
component of the Final Expansion Plans and Specifications to either approve or disapprove
each such component.

When
each component of the Final Expansion Plans and Specifications has been approved by
Tenant, Landlord and Tenant shall affix their respective signatures or initials to a
schedule describing each such approved component. Such approved components shall
constitute all or a portion of the Final Expansion Plans and Specifications and shall be
deemed to become attached to and made a part of this Lease as Exhibit H.

Section 2A.3 Expansion Commencement Date; Delivery of
Expansion Improvements.

(a)      Expansion Commencement Date. The
Expansion Commencement Date shall be the date on which the Expansion
Improvements are Substantially Completed. For purposes of this Amendment, the
Expansion Improvements shall be deemed to be Substantially Completed
(or Substantially Complete or Substantial Completion) on
the date the requisite governmental authority having jurisdiction has issued
with respect thereto a temporary certificate of occupancy. Notwithstanding the
foregoing, if Lenders Architect, or if none, the Expansion Architect, has
certified in writing that, as of a date certain set forth in such written
certification, the Expansion Improvements would have been Substantially
Completed but for a Tenant Extension, then the Expansion Improvements shall
nevertheless be deemed to be Substantially Completed for purposes of determining
the Expansion Commencement Date on the date certain set forth in Lenders
Architects or the Expansion Architects aforesaid certification.
Section 2.5(b) of the Lease is hereby amended to (A) add the following items to
the definition of Tenant Extension: . . . (D) Tenants failure to pay
for any Change Order when due, or (E) any Change Order related to a Soil
Conditions Adjustment (as defined in Section 2A.5 hereinafter). .
..; and (B) add the following items to the definition of Permitted Delays:
. . . (vi) unusually severe weather; (vii) delays in obtaining building
permits; or (viii) other acts or occurrences beyond the reasonable control of
Expansion Contractor, or its employees, agents, contractors, subcontractors,
sub-subcontractors or representatives. . . Landlord shall deliver
possession of the Expansion Improvements to Tenant on the Expansion Commencement
Date.

(b)      Scheduled Expansion Completion Date.
Subject to the conditions herein set forth, the anticipated Expansion
Commencement Date will be August 18, 2006 (Scheduled Expansion Completion
Date); provided, however, that Landlord shall use commercially reasonable
efforts to cause McShane Construction Corporation (Expansion
Contractor) (without the incurrence of overtime or similar type charges
unless requested by Tenant in writing and paid for by Tenant in advance at
Tenants sole cost and expense) to achieve the Expansion Commencement Date
as soon as practicable.

Section
2A.4 Scope of Work. Weather permitting, promptly following the approval of
the Final Expansion Plans and Specifications, Landlord shall cause to be
furnished, at Landlords sole cost and expense, all the material, labor and
equipment necessary for the commencement and completion of construction of the
Expansion Improvements. Landlord shall cause Expansion Contractor to construct
the Expansion Improvements in a good and workmanlike manner in substantial
accordance with the Final Expansion Plans and Specifications. In the event that
any materials specified in the Final Expansion Plans and Specifications are not
reasonably available to Landlord or Expansion Contractor, Landlord and Expansion
Contractor reserve the right to substitute materials of higher or equal quality
provided Tenant gives its approval, which approval shall not be unreasonably
withheld and which shall be deemed given if Tenant does not disapprove within
three (3) days after receipt of a substitution notification.

Landlord
acknowledges and agrees that Landlord will bear certain responsibility, as described in
this Section 2A.4, for assuring that the Final Expansion Plans and Specifications will be
in compliance with the ADA. (For purposes of this Section 2A.4, the term ADA
shall mean the ADA as theretofore amended and, with respect to the rules and regulations
thereunder, as theretofore issued.) The preparation of the Preliminary Expansion Plans and
Specifications by or for Landlord will be based on, among other things, Expansion
Architects knowledge of the ADA, as the ADA may then be customarily implemented in
non-user specific warehouse/distribution/office facilities constructed in the
Naperville/Aurora, Illinois commercial marketplace, as well as on the Preliminary
Expansion Plans and Specifications. As an integral part of its obligations during the
review, submittal and revision procedure set forth herein with respect to the Final
Expansion Plans and Specifications, Tenant shall inform Landlord of any and all necessary
changes thereto in order for the Demised Premises to be in compliance the ADA, with
respect to Tenants intended use of the Demised Premises. Landlord shall thereafter
cause to be made any and all such changes to the Final Expansion Plans and Specifications
of which Tenant informs it. However, anything in this Lease to the contrary
notwithstanding, any and all such changes in the Final Expansion Plans and Specifications
shall automatically and conclusively be deemed to be a Change Order to which Tenant has
agreed.

Section
2A.5 Expansion Change Orders. Tenant shall be allowed to request (and shall be deemed
to have agreed to) Change Orders with respect to the Expansion Improvements in the same
manner and with the same effect as Change Orders to the Initial Improvements; expressly
excepting, however, that notwithstanding anything to the contrary contained in Section
2.4: (i) if the Change Order Cost is less than the original charge for the work being
deleted or changed, the amount of actual costs savings up to but in no event exceeding
$100,000 in the aggregate for all Change Orders shall be credited to Tenant (with any cost
savings of $100,000 or more accruing solely to Landlord without credit to Tenant); (ii) if
the Change Order Cost is greater than the original charge for the work being changed, then
Tenant shall pay to Landlord such Change Order Cost simultaneously with execution of the
Change Order; and (iii) any Soil Conditions Adjustment shall automatically and
conclusively be deemed to be a Change Order to be paid at Tenants sole cost and
expense. For purposes hereof, a Soil Conditions Adjustment is any soil
conditions which differ materially from those recommended in the soil report and result in
an increase to cost of construction of the Expansion Improvements, including without
limitation, any condition which requires added structural or foundation support, the
importation or exportation of soil or fill to level the site or otherwise put the site in
readily buildable condition.

Section
2A.6 Warranty as to Expansion Improvements. Subject to Section 2A.4 hereof with
respect to compliance with ADA in regard to the Expansion Improvements, Landlord shall
cause Expansion Contractor to warrant to Tenant, for a period of one (1) year after
Substantial Completion of the Expansion Improvements (Warranty Period), that
the Expansion Improvements shall be constructed in substantial compliance with the Final
Expansion Plans and Specifications, and shall be free from defects in workmanship or
materials. After the conclusion of the Warranty Period, Landlord or Expansion Contractor,
as the case may be, shall assign and transfer to Tenant all assignable warranties then in
effect with respect to the Expansion Improvements which were given to Landlord or
Expansion Contractor in the first instance. Among other things, Landlord shall cause the
warranty on the roof (fifteen (15) years labor and material, plus five (5) additional
years material only) of the Expansion Improvements to be assigned and transferred jointly
to Tenant and Landlord. If during the Warranty Period, Tenant notifies Landlord, in
writing, of defective workmanship or materials in the construction of the Expansion
Improvements, Landlord shall notify Expansion Contractor to promptly cause such defect to
be corrected. Thereafter, the Warranty Period for the item or items which were defective
and were corrected pursuant to the preceding sentence, and only for such item or items,
shall continue for a period of one (1) year after the date of such correction.

Landlord
and Tenant hereby acknowledge and agree that with respect to any latent defects in
workmanship or materials in the construction of the Expansion Improvements, Landlord and
Tenant shall be governed by the provisions of Illinois statutory and common law,
including, without limitation, the provisions of 735 ILCS 5/13-214, as the same may be
amended, modified and interpreted from time to time.

Anything
in this Lease to the contrary notwithstanding, in the event that Tenant suffers or incurs
any indirect or consequential damages as a result of a breach of the foregoing warranty,
Tenant waives any claims with respect thereto against Landlord and agrees that Landlord
shall not be liable therefor.

The
warranty which is provided hereunder is limited in certain respects and is conditioned on
the following:

(a)      Tenant shall use the Expansion Improvements
only in accordance with the design capacities and criteria established therefor.
Tenant acknowledges that any misuse thereof may void the warranty hereunder, and
may void any manufacturers or other warranties which may be assigned to
Tenant hereunder.

(b)      In addition to the foregoing, the warranty
hereunder shall not extend to the electrical systems, plumbing systems, heating,
ventilating and air conditioning systems, fire protection systems or other
mechanical systems servicing the Expansion Improvements, unless said systems are
maintained and operated in compliance with the manufacturers
specifications therefor by one or more professionals experienced in the
maintenance and servicing of such systems, at least through the Warranty Period.

(c)      Any and all work required to be performed
under this Section 2A.6 (Warranty Work) shall not in any way include
or require Landlord or Expansion Contractor to perform any routine or
appropriate regular maintenance of the Expansion Improvements required to be
performed by Tenant during the Warranty Period (or thereafter) as part of
Tenants Repairs and Maintenance (as such term is defined in Section 6.2
hereof).

Section
2A.7 Expansion Punch List. Landlord, Expansion Contractor and Tenant shall, on the
date on which the Expansion Improvements are Substantially Completed, make a joint
physical inspection of the Expansion Improvements to list the remaining items of work to
be completed (Punch List Items). Landlord shall cause Expansion Contractor to
deliver, in writing, an unconditional promise to complete the Punch List Items within a
reasonable period of time in respect to each item, taking into account diligence and good
and workmanlike practices. Such time period shall not be longer than sixty (60) days,
subject to Permitted Delays (including, without limitation, the inability to obtain
supplies or other items on a timely basis and work which is weather-dependent), in the
event of which Permitted Delays, Expansion Contractor shall nonetheless diligently pursue
the completion of the Punch List Items as promptly as practicable. In the event of a
disagreement among or between the parties as to the inclusion or the exclusion of a Punch
List Item, the decision of the Expansion Architect, which decision shall be based solely
on the determination of whether the item in question was constructed in substantial
conformity with the Final Expansion Plans and Specifications shall control.

Section
2A.8 Limitation on Landlords Obligations. Anything in this Article 2A or
elsewhere in this Lease to the contrary notwithstanding, Landlords obligations under
this Article 2A are expressly made contingent on (a) there having been no material adverse
change in the financial condition or creditworthiness of Tenant, and (b) Landlords
ability to obtain all necessary approvals, consents and permits which at the time of the
proposed expansion are required by the City and any and all other governmental authorities
then having jurisdiction over the Demised Premises. Landlord shall use its best efforts in
regard to obtaining any and all such approvals, consents and permits.

5.      Base Rent. Effective as of the Expansion
Commencement Date, Section 3.1 of the Lease is hereby deleted in its entirety
and replaced with the following:

Section
3.1 Payment of Base Rent. As part of the consideration to be paid by Tenant to
Landlord under this Lease, and in accordance with the terms, provisions and conditions of
this Lease, Tenant shall pay base rent with respect to the Demised Premises as set forth
in this Article 3 (Base Rent) as follows:

(a)      Base Rent for Initial Term; First Renewal Term
and Second Renewal Term.

| | (i)     
               First 11 Years. During the first 11 years of the Initial Term, being from
               the Expansion Commencement Date through the date which is 11 years, less one (1)
               day thereafter, the annual Base Rent with respect to the Demised Premises shall
               be One Million Two Hundred Fifty-Eight Thousand One Hundred Thirty-Eight and
               20/100 Dollars ($1,258,138.20), subject to annual increases as hereafter
               provided. Commencing with the first Adjustment Date (as defined in Section
               3.1(b) hereafter) and continuing on each subsequent Adjustment Date thereafter,
               Base Rent during the first 11 years of the Initial Term shall be increased by an
               amount equal to the product of the then-current Base Rent being paid times the
               Adjustment Percentage (as defined in Section 3.1(b) hereafter), which increases
               shall be compounded. The increased annual Base Rent shall constitute the annual
               Base Rent due and payable until the next Adjustment Date throughout the first 11
               years of the Initial Term.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

               Years 12 through 15. During years 12 through 15 of the Initial Term,
               being from the date which is 12 years after the Expansion Commencement Date
               through the date which is 15 years, less one (1) day, after the Expansion
               Commencement Date, the annual Base Rent shall remain fixed during said years 12
               through 15 at the same annual Base Rent then payable during the eleventh
               (11th) year of the Initial Term.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iii)     
               Years 16 through 20. During years 16 through 20 of the Initial Term,
               being from the date which is 16 years after the Expansion Commencement Date
               through the Initial Termination Date, the annual Base Rent shall remain fixed
               during said years 16 through 20 at an annual rate equal to the result obtained
               by taking an annual Base Rent of $1,258,138.20 and having increased the same on
               each Adjustment Date over the first 15 years of the Initial Term and on the
               first day of the 16th year by applying the Adjustment Percentage to
               said amount on a compounded basis.

| | (iv)     
               First Renewal Term. In the event that Tenant elects to renew the term of
               this Lease for the First Renewal Term, then during the First Renewal Term, the
               Base Rent shall be equal to the greater of (A) the fair market base rent, as
               determined in accordance with Section 3.1(d) hereof (Fair Market Base
               Rent) or (B) the then-current annual Base Rent payable immediately prior
               to the First Renewal Term increased by two and one-half percent (2.5%). Base
               Rent payable during the First Renewal Term shall be increased annually on each
               Adjustment Date by an amount equal to the product of the then-current Base Rent
               being paid times the Adjustment Percentage, which increases shall be compounded.
               The increased annual Base Rent shall constitute the annual Base Rent due and
               payable until the next Adjustment Date throughout the First Renewal Term.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

               Second Renewal Term. In the event that Tenant elects to renew the term of
               this Lease for the Second Renewal Term, then during the Second Renewal Term, the
               Base Rent shall be equal to the greater of (A) Fair Market Base Rent or (B) the
               then-current annual Base Rent payable immediately prior to the Second Renewal
               Term increased by two and one-half percent (2.5%). Base Rent payable during the
               Second Renewal Term shall be increased annually on each Adjustment Date by an
               amount equal to the product of the then-current Base Rent being paid times the
               Adjustment Percentage, which increases shall be compounded. The increased annual
               Base Rent shall constitute the annual Base Rent due and payable until the next
               Adjustment Date throughout the Second Renewal Term.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b)      For purposes of this Article, the following
definitions shall apply:
| | -----------------------------------------------------------------------------

| | Adjustment
Date shall mean the first anniversary of the Expansion Commencement Date and each
subsequent anniversary thereafter, including any Renewal Terms if Tenant exercises its
option to renew pursuant to Section 1.5.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | Adjustment
Percentage shall mean the lesser of (A) the increase in the Consumer Price Index for
the then current Adjustment Date over the immediately preceding year, expressed as a
percentage or (B) two and one-half percent (2.5%) per annum; provided, however, the
Adjustment Percentage shall not be less than zero.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | Consumer
Price Index shall mean the Revised Consumer Price Index for Urban Wage Earners and
Clerical Workers, All Items (base index year 1982-84=100), for Chicago, Gary, Lake County,
IL-IN-WI, as published by the United States Department of Labor, Bureau of Labor
Statistics. If the manner in which the Consumer Price Index is determined by the Bureau of
Labor Statistics shall be substantially revised, including, without limitation, a change
in the base index year, an adjustment shall be made by Landlord in such revised index
which would produce results equivalent, as nearly as possible, to those which would have
been obtained if such Consumer Price Index had not been so revised. If the Consumer Price
Index shall become unavailable to the public because publication is discontinued, or
otherwise, or if equivalent data is not readily available to enable Landlord to make the
adjustment referred to in the preceding sentence, then Landlord will substitute therefor a
comparable index based upon changes in the cost of living or purchasing power of the
consumer dollar published by any other governmental agency or, if no such index shall be
available, then a comparable index published by a major bank or other financial
institution or by a university or a recognized financial publication.

(c)     
          Special Abatement Period. Provided no default by Tenant exists under this
          Lease, Base Rent for the first ninety (90) days of the Initial Term shall be
          abated and in lieu thereof Tenant shall pay to Landlord monthly Base Rent in the
          amount of $81,207.33 per month.

(d)      Determining Fair
Market Base Rent.

| | (i) | Landlord Proposal. In the event that Tenant has delivered a Renewal
                    Notice, then, not later than eleven (11) months prior to the last day of the
                    Initial Term or the last day of the First Renewal Term, as applicable, Landlord
                    shall notify Tenant, in writing, of Landlords determination of Fair Market
                    Base Rent for the Demised Premises for the succeeding Renewal Term
                    (Landlords Fair Market Rent Determination). Within ten (10)
                    days at the receipt of Landlords Fair Market Rent Determination, Tenant
                    shall advise Landlord, in writing, either that (A) Tenant accepts
                    Landlords Fair Market Rent Determination; or (B) Tenant chooses to have
                    the Fair Market Base Rent for the Demised Premises to be determined by
                    appraisal. If Tenant accepts Landlords Fair Market Rent Determination, the
                    Fair Market Base Rent for the Demised Premises to be used in calculating Base
                    Rent during the succeeding Renewal Term shall be that set forth in
