As provided therein, the entire unpaid principal balance of each Series A Note shall be due and payable on the Maturity Date thereof.

(b) On March 22, 2025 and each March 22 thereafter to and including March 22, 2028, the Company will prepay $10,000,000 principal amount (or such lesser principal amount as shall then be outstanding) of the Series B Notes at par and without payment of the Make-Whole Amount or any premium, provided that upon any partial prepayment of the Series B Notes pursuant to Section 8.7 or partial purchase of the Series B Notes pursuant to Section 8.5, the principal amount of each required prepayment of the Series B Notes becoming due under this Section 8.1 on and after the date of such prepayment shall be reduced in the same proportion as the aggregate unpaid principal amount of the Series B Notes is reduced as a result of such prepayment or purchase. As provided therein, the entire unpaid principal balance of each Series B Note shall be due and payable on the Maturity Date thereof.

Section 8.2. Optional Prepayments with Make-Whole Amount . The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the Notes, in an amount not less than $1,000,000 in the case of a partial prepayment, at 100% of the principal amount so prepaid, and the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 10 days and not more than 60 days prior to the date fixed for such prepayment unless the Company and the Required Holders agree to another time period pursuant to Section 17. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each holder of Notes a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the specified prepayment date.

Section 8.3. Allocation of Partial Prepayments . In the case of each partial prepayment of the Notes pursuant to Section 8.1 or Section 8.2, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment and any optional prepayment of Notes pursuant to Section 8.2 shall be applied in inverse order of their scheduled due dates.

Section 8.4. Maturity; Surrender, Etc. In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

Section 8.5. Purchase of Notes . The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with this Agreement and the Notes or (b) pursuant to an offer to purchase made by the Company pro rata to the holders of all Notes at the time outstanding upon the same terms and conditions (except to the extent necessary to reflect differences in the interest rates, currencies and maturities of the Notes of different Series), which offer shall remain outstanding for a reasonable period of time (not to be less than 15 days). Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer. If the Required Holders accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by the holders of the Notes of such offer shall be extended by the number of days necessary to give such remaining holders at least 15 days from receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment or prepayment of Notes pursuant to this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

Section 8.6. Make-Whole Amount .

The term “Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings: “Called Principal” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, with respect to the Called Principal of any Note, the sum of (a) 0.50% plus (b) the yield to maturity implied by the “Ask Yield(s)” reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (i) converting U.S. Treasury ▇▇▇▇ quotations to bond equivalent yields in accordance with accepted financial practice and (ii) interpolating linearly between the “Ask Yields” Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Note, the sum of (x) 0.50% plus (y) the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year comprised of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or Section 12.1.

“Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

Section 8.7. Offer to Prepay upon Change of Control.

(a) Notice of Change of Control or Control Event. The Company will, within five Business Days after any Responsible Officer has knowledge of the occurrence of any Change of Control or Control Event, give written notice of such Change of Control or Control Event to each holder of Notes unless notice in respect of such Change of Control (or the Change of Control contemplated by such Control Event) shall have been given pursuant to subparagraph (b) of this Section 8.7. If a Change of Control has occurred, such notice shall contain and constitute an offer to prepay Notes as described in subparagraph (c) of this Section 8.7 and shall be accompanied by the certificate described in subparagraph (g) of this Section 8.7.

(b) Conditions to Company Action. Neither Whitestone REIT nor the Company will take any action that consummates or finalizes a Change of Control unless at least 20 Business Days prior to such action the Company shall have given to each holder of Notes written notice containing and constituting an offer to prepay such Notes as described in Section 8.7(c), accompanied by the certificate described in Section 8.7(g), and subject to the provisions of Section 8.7(d), contemporaneously with such action, it prepays all Notes required to be prepaid in accordance with this Section 8.7; provided, that if Whitestone REIT or the Company have not received knowledge of a Control Event relating to such Change of Control at least 25 Business Days prior to the consummation or finalization of such Change of Control, then the restrictions contained in this Section 8.7(b) shall not apply to such Change of Control.

(c) Offer to Prepay Notes. The offer to prepay the Notes contemplated by paragraphs (a) and (b) of this Section 8.7 shall be an offer to prepay by the Company, in accordance with and subject to this Section 8.7, all, but not less than all, the Notes held by each holder (in this case only, “holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”) which shall be the effective date of the Change of Control. If such Proposed Prepayment Date is in connection with an offer contemplated by subparagraph (a) of this Section 8.7, such date shall be not less than 20 Business Days and not more than 45 days after the date of such offer (if the Proposed Prepayment Date shall not be specified in such offer, the Proposed Prepayment Date shall be the 20^th Business Day after the date of such offer).

(d) Acceptance. A holder of Notes may accept the offer to prepay made pursuant to this Section 8.7 by causing a notice of such acceptance to be delivered to the Company at least five Business Days prior to the Proposed Prepayment Date. A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 8.7 shall be deemed to constitute a rejection of such offer by such holder.

(e) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal amount of the Notes together with accrued and unpaid interest thereon but without any Make-Whole Amount, or other premium or penalty of any kind. The prepayment shall be made on the Proposed Prepayment Date except as provided in Section 8.7(f). The obligation of the Company to prepay the Notes pursuant to the offers required by subparagraph (c) and accepted in accordance with subparagraph (d) of this Section 8.7 is subject to the occurrence of the Change of Control in respect of which such offers and acceptances shall have been made.

(f) Deferral Pending Change of Control. The obligation of the Company to prepay Notes pursuant to the offers required by subparagraph (b) and accepted in accordance with subparagraph (d) of this Section 8.7 is subject to the occurrence of the Change of Control in respect of which such offers and acceptances shall have been made. In the event that such Change of Control does not occur on the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until and shall be made on the date on which such Change of Control occurs. The Company shall keep each holder of Notes reasonably and timely informed of (i) any such deferral of the date of prepayment, (ii) the date on which such Change of Control and the prepayment are expected to occur, and (iii) any determination by the Company that efforts to effect such Change of Control have ceased or been abandoned (in which case the offers and acceptances made pursuant to this Section 8.7 in respect of such Change of Control shall be deemed rescinded).

(g) Officer’s Certificate. Each offer to prepay the Notes pursuant to this Section 8.7 shall be accompanied by a certificate, executed by a Senior Financial Officer of the Company and dated the date of such offer, specifying: (i) the Proposed Prepayment Date; (ii) that such offer is made pursuant to this Section 8.7; (iii) the principal amount of each Note offered to be prepaid; (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions of this Section 8.7 have been fulfilled; and (vi) in reasonable detail, the nature and date or proposed date of the Change of Control.

(h) Certain Definitions.

“Change of Control” means any of (a) the acquisition by any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) at any time of beneficial ownership of 30% or more of the outstanding capital stock or other equity interests of Whitestone REIT or the Company on a fully‑diluted basis, other than acquisitions of such interests by any party who is an officer or trustee of Whitestone REIT or the Company as of the day of Closing, (b) the failure of individuals who are members of the board of trustees (or similar governing body) of Whitestone REIT on the day of Closing (together with any new or replacement trustees whose initial nomination for election was approved by a majority of the trustees who were either trustees on the day of Closing or previously so approved) to constitute a majority of the board of trustees (or similar governing body) of Whitestone REIT, (c) any “Change of Control” (or words of like import), as defined in any agreement or indenture relating to any issue of Indebtedness of the Company, Whitestone REIT or any Subsidiary shall occur, and (d) termination of the chief executive officer of the Company without cause, excluding non-appealable determinations by a court of law for fraud, gross negligence, or willful neglect, which would be considered termination for cause.

Section 9.9. ERISA .

Section 9.10. Most Favored Lender .

(a) If, on any date, Whitestone REIT, the Company or any its Subsidiaries enters into, assumes or otherwise becomes bound or obligated under any Material Credit Facility that contains one or more Additional Financial Covenants or Additional Defaults (including, for the avoidance of doubt, as a result any amendment to any Material Credit Facility, whether or not in effect on the date hereof, causing it to contain one or more Additional Financial Covenants or Additional Defaults), then, concurrently therewith, (i) the Company will notify the holders of the Notes thereof by delivery of an Officer’s Certificate of the Company to each holder of Notes specifying the nature of such Additional Financial Covenant(s) and/or Additional Default(s) and attaching a true, correct and complete copy of the amendment, amended and restated agreement or other modification, and (ii) whether or not the Company provides such notice, the terms of this Agreement shall, without any further action on the part of Whitestone REIT, the Company or any holder of the Notes, be deemed to be amended automatically to include each Additional Financial Covenant and each Additional Default in this Agreement. If requested by the Required Holders in writing, Whitestone REIT and the Company further covenant to promptly execute and deliver at their expense (including, without limitation, the fees and expenses of counsel for the holders of the Notes) an amendment to this Agreement in form and substance satisfactory to the Required Holders evidencing the amendment of this Agreement to include such Additional Financial Covenants and Additional Defaults in this Agreement, provided that the execution and delivery of such amendment shall not be a precondition to the effectiveness of such amendment as provided for in this clause (a), but shall merely be for the convenience of the parties hereto.

(b) If after the time this Agreement is amended pursuant to clause (a) of this Section 9.10 to include in this Agreement any Additional Financial Covenant or Additional Default (an “Incorporated Provision”) contained in any Material Credit Facility (the “Other Indebtedness Agreement”), such Incorporated Provision ceases to be in effect under or is deleted from such Other Indebtedness Agreement (or such Other Indebtedness Agreement is no longer a Material Credit Facility) or is amended or modified for the purposes of such Other Indebtedness Agreement so as to become less restrictive with respect to Whitestone REIT, the Company and its Subsidiaries, then, upon (i) delivery of an Officer’s Certificate of the Company to each holder of Notes (a) certifying that the conditions of this Section 9.10(b) have been satisfied and (b) either (1) if such Other Indebtedness Agreement has ceased to be in effect or ceased to constitute a Material Credit Facility, certifying to such fact or (2) if such Other Indebtedness Agreement has been amended, amended and restated or otherwise modified, attaching a true, correct and complete copy of the amendment, amended and restated agreement or other modification and (ii) payment of any fees required by clause (Y) below, the term of this Agreement shall, without any further action on the part of Whitestone REIT, the Company or any holder of Notes, be deemed to be amended automatically to delete or similarly amend or modify, as the case may be, such Incorporated Provision as in effect in this Agreement; provided that, if requested by the Company or the Required Holders in writing, Whitestone REIT, the Company and the holders of the Notes will promptly thereafter execute and deliver an amendment to this Agreement at the Company’s expense (including, without limitation, the fees and expenses of counsel for the holders of the Notes) reflecting such changes to this Agreement, provided, further, that (X) no Default or Event of Default shall be in existence immediately before or after such deletion, amendment or modification (including under such Incorporated Provision otherwise to be deleted, amended or modified), and (Y) if any fees or other remuneration were paid to any lender under such Other Indebtedness Agreement with respect to causing such Incorporated Provision to cease to be in effect or be deleted or to be so amended or modified, then the Company shall have paid to the holders of the Notes the same fees or other remuneration on a pro rata basis in proportion to the relative outstanding principal amounts of the Notes and the principal amount of the Indebtedness outstanding under such Other Indebtedness Agreement. Notwithstanding the foregoing, no amendment to this Agreement pursuant to this clause (b) as the result of any Incorporated Provision ceasing to be in effect or being deleted, amended or otherwise modified shall cause any covenant or Event of Default in this Agreement to be less restrictive as to Whitestone REIT, the Company or its Subsidiaries than such covenant or Event of Default as contained in this Agreement as in effect on the date hereof, and as amended other than as the result of the application of clause (a) of this Section 9.10 originally caused by such Incorporated Provision in such Other Indebtedness Agreement.

Upon any Notes becoming due and payable under this Section 12.1, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including interest accrued thereon at the Default Rate) and (y) the Make-Whole Amount determined in respect of such principal amount, shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

Section 12.2. Other Remedies . If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

Section 12.3. Rescission . At any time after any Notes have been declared due and payable pursuant to Section 12.1(b) or (c), the Required Holders, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) neither the Company nor any other Person shall have paid any amounts which have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and (d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon.

Section 12.4. No Waivers or Election of Remedies, Expenses, Etc . No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or remedy conferred by this Agreement or any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including reasonable attorneys’ fees, expenses and disbursements.


SECTION 13.	REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES .

Section 13.1. Registration of Notes . The Company shall keep at its principal executive office a register for the registration and registration of transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. If any holder of one or more Notes is a nominee, then (a) the name and address of the beneficial owner of such Note or Notes shall also be registered in such register as an owner and holder thereof and (b) at any such beneficial owner’s option, either such beneficial owner or its nominee may execute any amendment, waiver or consent pursuant to this Agreement. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders of Notes.

Section 13.2. Transfer and Exchange of Notes; Limitation on Transfers to Competitors .

(a) Upon surrender of any Note to the Company at the address and to the attention of the designated officer (all as specified in Section 18(iii)), for registration of transfer or exchange (and in the case of a surrender for registration of transfer accompanied by a written instrument of transfer duly executed by the registered holder of such Note or such holder’s attorney duly authorized in writing and accompanied by the relevant name, address and other information for notices of each transferee of such Note or part thereof), within 10 Business Days thereafter, the Company shall execute and deliver, at the Company’s expense (except as provided below), one or more new Notes of the same series (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Schedule 1(a) or Schedule 1(b), as applicable. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in denominations of less than $500,000, provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes of a series, one Note of such series may be in a denomination of less than $500,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 6.2.

(b) Without limiting the foregoing, each Purchaser and each subsequent holder of any Note severally agrees that, so long as no Event of Default under clauses (a), (b), (g), (h) or (i) of Section 11 or any Specified Event of Default shall be in existence, it will not knowingly resell any Note purchased by it to a Person which is a Competitor (it being understood that such Purchaser shall advise any broker or intermediary acting on its behalf that such resale to a Competitor is prohibited hereby). In determining whether any proposed transferee is a Competitor, Prudential, a Purchaser or other holder of a Note may conclusively rely in good faith on a written statement from such transferee that such transferee is not a Competitor.

Section 13.3. Replacement of Notes . Upon receipt by the Company at the address and to the attention of the designated officer (all as specified in Section 18(iii)) of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and

(a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note of the same series with a minimum net worth of at least $50,000,000 or a Qualified Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or

(b) in the case of mutilation, upon surrender and cancellation thereof,

within 10 Business Days thereafter, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

Section 14.2. Payment by Wire Transfer . So long as any Purchaser or its nominee shall be the holder of any Note, and notwithstanding anything contained in Section 14.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, interest and all other amounts becoming due hereunder by the method and at the address specified for such purpose below such Purchaser’s name in the Purchaser Schedule, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 14.1. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 13.2. The Company will afford the benefits of this Section 14.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by a Purchaser under this Agreement and that has made the same agreement relating to such Note as the Purchasers have made in this Section 14.2.

Section 14.3. FATCA Information . By acceptance of any Note, the holder of such Note agrees that such holder will with reasonable promptness duly complete and deliver to the Company, or to such other Person as may be reasonably requested by the Company, from time to time (a) in the case of any such holder that is a United States Person, such holder’s United States tax identification number or other Forms reasonably requested by the Company necessary to establish such holder’s status as a United States Person under FATCA and as may otherwise be necessary for the Company to comply with its obligations under FATCA and (b) in the case of any such holder that is not a United States Person, such documentation prescribed by applicable law (including as prescribed by section 1471(b)(3)(C)(i) of the Code) and such additional documentation as may be necessary for the Company to comply with its obligations under FATCA and to determine that such holder has complied with such holder’s obligations under FATCA or to determine the amount (if any) to deduct and withhold from any such payment made to such holder. Nothing in this Section 14.3 shall require any holder to provide information that is confidential or proprietary to such holder unless the Company is required to obtain such information under FATCA and, in such event, the Company shall treat any such information it receives as confidential.

This Section 19 shall not prohibit the Company or any other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.


SECTION 20.	CONFIDENTIAL INFORMATION .

For the purposes of this Section 20, “Confidential Information” means information delivered to any Purchaser by or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Purchaser as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary or (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly available. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, officers, employees, agents, attorneys, trustees and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its auditors, financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with this Section 20, (iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or offers to sell such Note or any part thereof or any participation therein (but only if such Person has entered into a confidentiality agreement in relation thereto), (v) any Person from which it offers to purchase any Security of the Company (but only if such Person has entered into a confidentiality agreement in relation thereto), (vi) any federal or state regulatory authority having jurisdiction over such Purchaser, (vii) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s investment portfolio, or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser’s Notes or this Agreement. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying this Section 20.

In the event that as a condition to receiving access to information relating to the Company or its Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Note is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual workspace or otherwise) which is different from this Section 20, this Section 20 shall not be amended thereby and, as between such Purchaser or such holder and the Company, this Section 20 shall supersede any such other confidentiality undertaking.


SECTION 21.	SUBSTITUTION OF PURCHASER .

Each Purchaser shall have the right to substitute any one of its Affiliates or another Purchaser or any one of such other Purchaser’s Affiliates (a “Substitute Purchaser”) as the purchaser of the Notes that it has agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Substitute Purchaser, shall contain such Substitute Purchaser’s agreement to be bound by this Agreement and shall contain a confirmation by such Substitute Purchaser of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Substitute Purchaser in lieu of such original Purchaser. In the event that such Substitute Purchaser is so substituted as a Purchaser hereunder and such Substitute Purchaser thereafter transfers to such original Purchaser all of the Notes then held by such Substitute Purchaser, upon receipt by the Company of notice of such transfer, any reference to such Substitute Purchaser as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Substitute Purchaser, but shall refer to such original Purchaser, and such original Purchaser shall again have all the rights of an original holder of the Notes under this Agreement.


SECTION 22.	MISCELLANEOUS .

Section 22.1. Successors and Assigns . All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including any subsequent holder of a Note) whether so expressed or not, except that, subject to Section 10.3, the Company may not assign or otherwise transfer any of its rights or obligations hereunder or under the Notes without the prior written consent of each holder. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto and their respective successors and assigns permitted hereby) any legal or equitable right, remedy or claim under or by reason of this Agreement.

Section 22.2. Accounting Terms; Divisions .

(a) All accounting terms used herein which are not expressly defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and (ii) all financial statements shall be prepared in accordance with GAAP. For purposes of determining compliance with this Agreement (including Section 9, Section 10 and the definition of “Indebtedness”), any election by the Company to measure any financial liability using fair value (as permitted by Financial Accounting Standards Board Accounting Standards Codification Topic No. ▇▇▇-▇▇-▇▇ – Fair Value Option, International Accounting Standard 39 – Financial Instruments: Recognition and Measurement or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been made.

(b) If, after the date of this Agreement, there shall occur any change in GAAP from those used in the preparation of the financial statements referred to in Section 5.5 hereof and such change shall result in a change in the method of calculation of any financial covenant, standard or term found in this Agreement, either the Company or the Required Holders may by written notice to the holders of Notes and the Company, respectively, require that the holders of Notes and the Company negotiate in good faith to amend such financial covenants, standards, and terms so as equitably to reflect such change in accounting principles, with the desired result being that the criteria for evaluating the financial condition of the Company and its Subsidiaries shall be the same as if such change had not been made. No delay by the Company or the Required Holders in requiring such negotiation shall limit their right to so require such a negotiation at any time after such a change in accounting principles. Until any such financial covenant, standard, or term is amended in accordance with this Section 22.2(b), such financial covenants, standards and terms shall be computed and determined in accordance with GAAP in effect prior to such change in accounting principles. Without limiting the generality of the foregoing, the Company shall neither be deemed to be in compliance with any such financial covenant, standard or term hereunder nor out of compliance with any such financial covenant, standard or term, if such state of compliance or noncompliance, as the case may be, would not exist but for the occurrence of a change in accounting principles after the date hereof.

(c) For all purposes under the Note Documents, in connection with any division or plan of division (whether under Delaware law or any comparable event under a different jurisdiction’s laws): (a) if any asset, right, obligation or liability of any Person becomes the asset, right, obligation or liability of a different Person, then it shall be deemed to have been transferred from the original Person to the subsequent Person, and (b) if any new Person comes into existence, such new Person shall be deemed to have been organized on the first date of its existence by the holders of its equity interests at such time.

Section 22.3. Severability . Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

Section 22.4. Construction, Etc . Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

Defined terms herein shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” The word “will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise (a) any definition of or reference to any agreement, instrument or other document herein shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein) and, for purposes of the Notes, shall also include any such notes issued in substitution therefor pursuant to Section 13, (b) subject to Section 22.1, any reference herein to any Person shall be construed to include such Person’s successors and assigns, (c) the words “herein,” “hereof” and “hereunder,” and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (d) all references herein to Sections and Schedules shall be construed to refer to Sections of, and Schedules to, this Agreement, and (e) any reference to any law or regulation herein shall, unless otherwise specified, refer to such law or regulation as amended, modified or supplemented from time to time.

Section 22.5. Counterparts . This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

Section 22.6. Governing Law . This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York excluding choice‑of‑law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State.

Section 22.7. Jurisdiction and Process; Waiver of Jury Trial .

In case of failure by the Company or other obligor punctually to pay any obligations guaranteed hereby, each Guarantor hereby unconditionally agrees to make such payment or to cause such payment to be made punctually as and when the same shall become due and payable, whether at stated maturity, by acceleration, or otherwise, and as if such payment were made by the Company or such obligor.

Section 23.2. Guarantee Unconditional . The obligations of each Guarantor under this Section 23 shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged, or otherwise affected by:

(a) any extension, renewal, settlement, compromise, waiver, or release in respect of any obligation of the Company or other obligor or of any other guarantor under this Agreement or the Notes or by operation of law or otherwise;

(f) any application of any sums by whomsoever paid or howsoever realized to any obligation of the Company or other obligor, regardless of what obligations of the Company or other obligor remain unpaid;

(g) any invalidity or unenforceability relating to or against the Company or other obligor or any other guarantor for any reason of this Agreement or of any Note or any provision of applicable law or regulation purporting to prohibit the payment by the Company or other obligor or any other guarantor of the principal of or interest on any Note or any other amount payable under this Agreement or the Notes; or

(h) any other act or omission to act or delay of any kind by any Purchaser or other holder of a Note, or any other Person or any other circumstance whatsoever that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of the obligations of any Guarantor under this Section 23.

Section 23.3. Discharge Only Upon Payment in Full; Restatement in Certain Circumstances . Except as otherwise set forth in Section 9.7 hereof, each Guarantor’s obligations under this Section 23 shall remain in full force and effect until the principal of and interest on the Notes and all other amounts payable by the Company and the Guarantors under this Agreement and the Notes shall have been paid in full. If at any time any payment of the principal of or interest on any Note or any other amount payable by the Company or other obligor or any Guarantor under the Agreement or the Notes is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy, or reorganization of the Company or other obligor or of any guarantor, or otherwise, each Guarantor’s obligations under this Section 23 with respect to such payment shall be reinstated at such time as though such payment had become due but had not been made at such time.

Section 23.4. Subrogation . Each Guarantor agrees it will not exercise any rights which it may acquire by way of subrogation by any payment made hereunder, or otherwise, until all the obligations guaranteed hereby shall have been paid in full. If any amount shall be paid to a Guarantor on account of such subrogation rights at any time prior to the payment in full of the Notes and all other amounts payable by the Company hereunder, such amount shall be held in trust for the benefit of the holders of the Notes and shall forthwith be paid to the holders of the Notes in accordance with the terms of this Agreement.

Section 23.5. Waivers . Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest, and any notice except as specifically provided for herein, as well as any requirement that at any time any action be taken by any holder of a Note or any other Person against the Company or other obligor, another guarantor, or any other Person.

Section 23.6. Limit on Recovery. Notwithstanding any other provision hereof, the right of recovery against each Subsidiary Guarantor under this Section 23 shall not exceed $1.00 less than the lowest amount which would render such Subsidiary Guarantor’s obligations under this Section 23 void or voidable under applicable law, including, without limitation, fraudulent conveyance law.

Section 23.7. Stay of Acceleration . If acceleration of the time for payment of any amount payable by the Company or other obligor under this Agreement or the Notes, is stayed upon the insolvency, bankruptcy or reorganization of the Company or such obligor, all such amounts otherwise subject to acceleration under the terms of this Agreement or the Notes, shall nonetheless be payable by the Guarantors hereunder forthwith on demand by the Required Holders.

Section 23.8. Benefit to Guarantors .

Each Guarantor will derive substantial direct and indirect benefit from the extensions of credit hereunder.

Section 23.9. Guarantor Consents . Each Guarantor shall take such action as the Company is required by this Agreement to cause such Guarantor to take, and shall refrain from taking such action as the Company is required by this Agreement to prohibit such Guarantor from taking.

Section 23.10. Subordination . Each Guarantor (each referred to herein as a “Subordinated Creditor”) hereby subordinates the payment of all indebtedness, obligations, and liabilities of the Company or other Guarantor owing to such Subordinated Creditor, whether now existing or hereafter arising, to the indefeasible payment in full in cash of the Notes and all other obligations hereunder. During the existence of any Event of Default, subject to Section 23.4, any such indebtedness, obligation, or liability of the Company or other Guarantor owing to such Subordinated Creditor shall be enforced and performance received by such Subordinated Creditor as trustee for the benefit of the holders of the Notes and the proceeds thereof shall be paid over to the holders of the Notes (whether or not then due), but without reducing or affecting in any manner the liability of such Guarantor under this Section 23.

Internal Accounting Matters

As previously announced by Whitestone REIT on February 26, 2019, the Audit Committee of the Board of Trustees (the “Audit Committee”) of Whitestone REIT, after consultation with members of senior management of Whitestone REIT, concluded that Whitestone REIT’s unaudited consolidated financial statements as of and for the periods ended March 31, 2018, June 30, 2018 and September 30, 2018 (collectively, the “2018 Quarterly Financial Statements”) included in the Company’s Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2018, June 30, 2018 and September 30, 2018, respectively, should be restated to correct an accounting error.

In connection with the determination that the 2018 Quarterly Financial Statements should be restated to correct such accounting error, management of Whitestone REIT, under the supervision and with the participation of Whitestone REIT’s Chief Executive Officer and Chief Financial Officer, has carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of December 31, 2018. Based upon that evaluation, and in light of the material weakness in the design and operation of Whitestone REIT’s internal control over financial reporting disclosed below, Whitestone REIT’s Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, Whitestone REIT’s disclosure controls and procedures were not effective at the reasonable assurance level referenced above. In designing and evaluating disclosure controls and procedures, management of Whitestone REIT recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Management of Whitestone REIT is required to apply judgment in evaluating the cost benefit relationship of possible controls and procedures.

Management of Whitestone REIT, under the supervision of the Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(e) under the Securities Exchange Act of 1934, as amended). Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with GAAP, and includes those policies and procedures that:


•	pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and dispositions of our assets;

SCHEDULE 9.6
(to Note Purchase and Guaranty Agreement)


•	provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and


•	provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Whitestone REIT’s management conducted a process to assess the effectiveness of its internal control over financial reporting as of December 31, 2018, based on the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the ▇▇▇▇▇▇▇▇ Commission, or COSO. This framework highlights that the control environment sets the tone of the organization, influences the control consciousness of its people, and is the foundation for all other components of internal control over financial reporting.

During the assessment process, Whitestone REIT identified the following material weakness as of December 31, 2018 in its internal controls over financial reporting and disclosure controls and procedures.

•

Application of New Accounting Pronouncements, including proper assessment of judgment items in complex accounting transactions – Whitestone REIT did not have effective controls to ensure the proper application of new accounting pronouncements in its financial statements. After review of the error and internal controls over financial reporting and disclosure controls and procedures, Whitestone REIT determined that it did not appropriately weigh its legal rights in its assessment of the transfer of control criteria under Topic 606 as it pertained to a transaction entered into in 2016.

The material weakness described above contributed to accounting errors that required the aforementioned restatement of the 2018 Quarterly Financial Statements.

S-9.6-2

As a result of the material weakness described above, Whitestone REIT’s management has concluded that, as of December 31, 2018, its internal control over financial reporting was not effective.

Whitestone REIT’s independent registered public accounting firm has issued a report on the effectiveness of Whitestone REIT’s internal control over financial reporting.

Whitestone REIT’s management, under the supervision of its Chief Executive Officer and Chief Financial Officer, and with the oversight of the Audit Committee, has undertaken a plan to remediate the material weakness identified above. The remediation efforts summarized below, which are either implemented or in the process of being implemented, are intended to address the identified material weakness.


•	Enhancements to internal controls regarding the adoption of new accounting pronouncements including:


◦	Enhanced documentation of the details of new accounting pronouncements;


◦	Enhanced documentation of areas in new accounting pronouncements that require the exercise of the judgment of Whitestone REIT’s management; and


◦	Enhanced documentation of the applicability of new accounting pronouncements to Whitestone REIT’s business.


•	Engagement of outside technical experts to assist Whitestone REIT in the application and adoption of new accounting pronouncements.


•	Ensure key accounting personnel have appropriate training.


•	Additional accounting staff with appropriate experience, certification, education and training.


•	Implementation of a disclosure review committee, including outside technical advisors, the Chief Financial Officer, accounting staff, and other members of management of Whitestone REIT. The committee will meet quarterly, at a minimum, to provide guidance and oversight to ensure the proper implementation of the enhanced internal controls regarding the adoption of new accounting pronouncements.

S-9.6-3


•	Quarterly review with the Audit Committee of new accounting pronouncements, including a discussion of key judgment areas.

Other than the foregoing, there have been no changes during Whitestone REIT’s quarter ended December 31, 2018, in Whitestone REIT’s internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, Whitestone REIT’s internal control over financial reporting.
