All rebates or reductions in Property Taxes received subsequent to Closing relating to periods prior to Closing, net of costs of obtaining the same, shall be prorated as of the Redemption Apportionment Date, when received. If as of the Redemption Apportionment Date the Company Projects or any portion thereof shall be affected by any special or general assessments which are or may become payable in installments of which any installment is then a lien and has become due and payable, such currently due and payable installment(s) shall be allocated to the period prior to the Redemption Apportionment Date and all installments not due and payable on the Redemption Apportionment Date shall be allocated to the period after the Redemption Apportionment Date.

8.4.5 Utilities.

The Company, with respect to the PKY Projects, and CalSTRS, with respect to the CalSTRS Projects, shall receive its pro rata share of any rental insurance proceeds which relate to the period prior to the Redemption Apportionment Date if and to the extent any such proceeds are delivered to any Owner Entities.

Notwithstanding the foregoing sentence, to the extent any Leasing Costs or Building Capital Expenditures set forth on Schedule 8.4.7.5 are subsequently paid by the Company or the applicable Owner Entity between October 1, 2014 and the Redemption Apportionment Date, then either PKY or CalSTRS shall reimburse the Company for such Leasing Costs and Building Capital Expenditures because their impact (as set forth on Schedule 8.4.7.5) was fully accounted for as of September 30, 2014, and at Closing such reimbursement shall be made in connection with the Final Closing Statement pursuant to Section 8.4.15.1 below.

(b) To the extent any Leasing Costs and Building Capital Expenditures that are not set forth on Schedule 8.4.7.5 are paid between October 1, 2014 and the Closing Date, such Leasing Costs and Building Capital Expenditures shall not be adjusted at Closing, but rather shall be adjusted in connection with the preparation of the Final Closing Statement pursuant to Section 8.4.15.1 below.

Any such reconciliation shall be prepared or caused to be prepared by CalSTRS, in the case of the CalSTRS Projects, and the Company in the case of the PKY Projects and shall be completed no later than April 1, 2015. CalSTRS, in the case of the CalSTRS Projects, and the Company, in the case of the PKY Projects, shall provide to the Company or CalSTRS, as applicable, the amount of any Pre-Closing Reimbursements due from or to each tenant and shall provide to the Company or CalSTRS, as applicable, all reasonably requested documentation in connection therewith. CalSTRS, in the case of the CalSTRS Projects, and the Company in the case of the PKY Projects shall cause the applicable Owner Entity to then invoice each tenant for such Pre-Closing Reimbursements with the next invoice such Owner Entity sends to each tenant. If the amount of Pre-Closing Reimbursements collected with respect to a particular Company Project for such prior time period is less than the amount of reimbursable Pre-Closing Reimbursements paid by the applicable Owner Entity for such period, then the applicable Owner Entity shall ▇▇▇▇ such tenants for such amounts and shall pay any such amounts received 60% to CalSTRS and 40% to PKY (a portion of which shall be treated as an adjustment to the Membership Interest Purchase Price pursuant to Section 8.4.1). If the amount of Pre-Closing Reimbursements collected by an Owner Entity for such prior calendar year exceeds the amount of Pre-Closing Reimbursements expenses paid by such Owner Entity with respect to such period, then, to the extent required under the terms of the Leases, CalSTRS shall remit 60% of such excess amount to PKY, if relating to a PKY Project, and the Company shall remit 40% of such excess amount to CalSTRS if relating to a CalSTRS Project (a portion of which shall be

treated as an adjustment to the Membership Interest Purchase Price pursuant to Section 8.4.1).

8.4.15.2.2 To the extent that any tenant conducts an audit respecting rent or any other charges paid by tenant for any periods prior to the Closing Date, the applicable Owner Entity shall be solely responsible for responding to such audit request and complying with all requirements under the Leases (and at law or in equity) in connection therewith. If any tenant becomes entitled to a refund of rent or any other charge with respect to a period prior to the Closing Date, any such refunds due to such Tenant shall be borne 60% by CalSTRS and 40% by PKY collectively, to be shared among them pursuant to the principles set forth in Section 8.4.1, a portion of which may be treated as an adjustment to the Membership Interest Purchase Price pursuant to Section 8.4.1.

8.4.15.2.3 PKY Austin and CalSTRS acknowledge that certain employee costs that may be passed through to tenants of the Company Projects that have been incurred prior to the date hereof as operating expenses have not yet been passed through to tenants.. As these costs are passed through and paid by tenants subsequent to the Closing Date they shall be treated as collected Rents and allocated between CalSTRS and the Company in accordance Section 8.4.3 as and when received.

8.4.16 Interest. If any payment to be made after the Closing under this Section 8.4 shall not be paid when due hereunder, the same shall bear interest (which shall be paid together with the applicable payment hereunder) from the date due until so paid at a rate per annum equal to the Prime Rate (as such rate may vary from time to time) as reported in The Wall Street Journal plus five percent (5%) (the "Default Rate"). To the extent a payment provision in this Section 8.4 does not specify a period for payment, then for purposes hereof such payment shall be due within ten (10) calendar days of the date such payment obligation is triggered.

8.4.17 INTENTIONALLY DELETED.

8.4.18 Survival. The provisions of this Section 8.4 shall survive the Closing.

8.5 Tax Returns; Income Taxes.

(a) PKY shall be responsible for timely preparing (or causing to be prepared) tax returns (if any) of or with respect to the Company, Portfolio Holdings, the Mezzanine Owners, the Owner Entities, and the Company Projects for taxable periods which either ended before or which include the Closing Date, other than a taxable period beginning on the Closing Date (the “Pre-Closing Tax Returns”, which term shall not be deemed to include the Texas Franchise Tax Public Information Reports). PKY shall be responsible for timely filing (or causing to be timely filed), taking into account any extensions the Pre-Closing Tax Returns (if any) of or with respect to each of the Company, Portfolio Holdings, the PKY Mezzanine Owners, the PKY Owner Entities, and the PKY Projects, which the parties acknowledge for Texas Franchise Tax purposes is anticipated to include a consolidated/combined/unitary tax that includes the Company, Portfolio Holdings, the Mezzanine Owners, the Owner Entities and the Projects) and would include the CalSTRS Owner Entities and

CalSTRS Mezzanine Owners for the period ending on the Closing Date) Except to the extent otherwise exempt, CalSTRS shall be responsible for timely preparing (or causing to be prepared), to the extent not otherwise required to by prepared by PKY pursuant to the first sentence of this Section 8.5(a), and timely filing (or causing to be timely filed) all other tax returns (including any Texas Franchise Tax Public Information Reports of each of the CalSTRS Mezzanine Owners, the CalSTRS Owner Entities, and the CalSTRS Projects.

(b) Any liability for income, franchise or similar taxes (including any “Texas franchise tax” or “Texas margin tax”) (collectively, “Income Taxes”) of the Company, Portfolio Holdings, the Mezzanine Owners and the Owner Entities for tax periods (or portions thereof) ending on or before the Closing Date shall be allocated 60% to CalSTRS and 40% to PKY.

The parties agree and acknowledge that the intent of this allocation is for CalSTRS, on the one hand, and PKY, on the other hand, to bear the liability for Income Taxes for the period beginning after the Closing Date attributable to the ownership and operation of the CalSTRS Projects and the PKY Projects, respectively, and shall be interpreted in a manner consistent with that purpose. Income Taxes, as necessary, shall be adjusted either in connection with the Preliminary Closing Statement or the Final Closing Statement (or otherwise if not possible to be adjusted in connection with the Preliminary Closing Statement or Final Closing Statement). To the extent permitted by law, the taxable years of the Company, Portfolio Holdings, each of the Mezzanine Owners and each of the Owner Entities for Income Taxes shall be closed as of the Closing Date.
