The provisions of this Section 5.7 shall survive indefinitely any Closing or termination of this Agreement and shall not be merged into the Closing documents.



Section 5.8 Hazardous Materials Waiver. Except with regard to any liability on the part of Seller for

-16-



---

Property in Sellers possession. Purchaser has ordered an update of the Entranco survey from W&H Pacific (collectively the
Survey).



Section 6.2 Title
Commitment.



(a) Purchaser has
requested the Title Company to furnish to Purchaser and Seller a preliminary report (the Commitment) for an owners policy of title insurance in ALTA form, together with legible copies of all documents referenced as
exceptions therein (the Title Documents).



(b) Purchaser shall have until 3:00 p.m. Pacific Standard Time on the date ten (10) days after the Effective Date to object in writing to any exceptions or matters shown on or disclosed by the Commitment, the
Title Documents or the Survey (individually, a Title Objection and collectively, the Title Objections). Unless Purchaser shall timely object to any exceptions or matters shown on or disclosed by the Commitment,
the Title Documents, or the Survey, all such exceptions and matters shall be deemed to constitute additional Permitted Exceptions. Seller may elect (but, subject to Section 6.2(c), shall not be obligated) to remove or cause to be
removed, or insured over, at Sellers expense, any Title Objections, and shall be entitled to a reasonable adjournment of the Closing (not to exceed thirty (30) days) for the purpose of such removal, which removal shall be deemed effected
by the issuance of title insurance, in form and substance acceptable to Purchaser, eliminating or insuring against the effect of the Title Objections. Seller shall notify Purchaser in writing within five (5) Business Days after receipt of
Purchasers notice of Title Objections whether Seller elects to remove or attempt to obtain title insurance endorsing over the same. If Seller fails to provide such notice, Seller shall be deemed to have elected not to cure such Title
Objections. If Seller elects not to remove or endorse over one or more Title Objections, Purchaser may terminate this Agreement as provided in Section 5.5. If Seller elects to remove or attempt to obtain title insurance endorsing over
the Title Objections and Seller does not remove or endorse over any Title Objections in a manner reasonably acceptable to Purchaser prior to the Closing, then, Purchaser may either (i) terminate this Agreement by giving written notice of such
termination to Seller and the Title Company, in which event the Title Company shall return the Earnest Money Deposit (and any interest accrued thereon) to Purchaser, Purchaser shall promptly return the Purchasers Information to Seller in
accordance with Section 5.3(c), the parties shall equally share the Cancellation Charges) and thereafter the parties shall have no further rights or obligations hereunder except for the Termination Surviving Obligations; or
(ii) waive such Title Objections, in which event such Title Objections shall be deemed additional Permitted Exceptions and the Closing shall occur as herein provided without any reduction of or credit against the Purchase Price. Purchaser shall
be deemed to have elected to waive such Title Objections pursuant to clause (ii) of the preceding sentence in the event Purchaser has not terminated this Agreement pursuant to clause (i) of the preceding sentence within two
(2) business days after Purchaser receives notice that such Title Objections will not be cured to Purchasers reasonable satisfaction.



(c) Notwithstanding any provision of this Section 6.2 to the contrary, Seller will be obligated to cure exceptions to title to
the Property relating to (i) liens and security interests securing loans obtained by Seller, (ii) any other monetary liens or security interests not created by Purchaser, (iii) all taxes and assessments due and payable for any period
prior to the



-17-



---

Closing, and (iv) all exceptions or matters created by Seller after the effective date of this Agreement without the prior written consent of Purchaser
(which consent may be withheld in Purchasers sole and absolute discretion). If, prior to the Closing, Seller does not remove any of the foregoing exceptions, then Purchaser may (x) terminate this Agreement by delivering written notice of
such termination to Seller and the Title Company, in which event the Title Company shall return the Earnest Money Deposit (and any interest accrued thereon) to Purchaser, Purchaser shall return the Purchasers Information to Seller in
accordance with Section 5.3(c), the parties shall equally share the Cancellation Charges and thereafter the parties shall have no further rights or obligations hereunder except for the Termination Surviving Obligations; (y) waive
Sellers performance hereunder, in which event such exceptions shall be deemed additional Permitted Exceptions and the Closing shall occur as herein provided, without any reduction of or credit against the Purchase Price except that if the
exception not removed is a lien described in this subsection (c)(i), (ii), or (iii), Purchaser shall be entitled to a credit against the Purchase Price in the amount of such lien, or (z) seek specific performance of this Agreement.



Section 6.3 Title Insurance. At Closing, the Title
Company shall issue to Purchaser or be irrevocably committed to issue to Purchaser an ALTA Extended Coverage Owners Policy of Title Insurance in the amount of the Purchase Price, insuring fee simple title to the Real Property and the
Improvements is vested in Purchaser in the form of, and with the endorsements contained in, the Commitment, subject only to the Permitted Exceptions (the Title Policy). Purchaser, at Purchasers expense, shall be entitled to
request that the Title Company provide such endorsements to the Title Policy as Purchaser may require, provided that the Closing shall not be delayed as a result of Purchasers request for such endorsements.

---

any proceeds of business interruption or rent continuation insurance applicable to the period prior to Closing, and Purchaser shall receive a credit against
the Purchase Price equal to the amount of any deductible under Sellers insurance applicable to such occurrences; or (y) to terminate this Agreement. Purchasers failure to deliver either of such notices to Seller and Title Company

and all interest accrued thereon will be returned to Purchaser, the parties shall equally share the Cancellation Charges, and thereafter neither Seller nor Purchaser will have any further rights or obligations to the other hereunder except with

paid or payable to Seller in connection with such occurrences, exclusive of any proceeds of business interruption or rent continuation insurance applicable to the period prior to Closing, in which event Purchaser shall receive a credit against the
Purchase Price equal to the amount of any deductible under Sellers insurance applicable to such occurrences.

received by Seller attributable to the Property from such condemnation or eminent domain proceeding, and (y) transfer and assign to Purchaser any and all rights Seller may have with respect to payments by or from and with respect to recovery
against any party for damages or compensation relating to the Property on account of such condemnation or eminent domain proceeding. A failure by Purchaser to notify Seller in writing within five (5) business days after receiving written notice
of such taking shall be deemed an election to proceed under clause (b) in this subsection. If Purchaser elects to proceed under clause (a) in this subsection, Seller shall not compromise, settle or adjust any claims to such
award without Purchasers prior written consent. In the event Purchaser notifies Seller (or is deemed to have notified Seller) of its election to terminate this Agreement pursuant to clause (b) above, the Earnest Money Deposit and

(A) TERMINATE THIS AGREEMENT, IN WHICH EVENT: (I) PURCHASER WILL RECEIVE FROM THE TITLE COMPANY THE EARNEST MONEY
DEPOSIT; AND (II) SELLER AND PURCHASER WILL HAVE NO FURTHER RIGHTS OR OBLIGATIONS UNDER THIS AGREEMENT, EXCEPT WITH RESPECT TO THE TERMINATION SURVIVING OBLIGATIONS; OR



(B) PURSUE SPECIFIC PERFORMANCE OF THIS AGREEMENT SO LONG AS ANY ACTION OR PROCEEDING FOR SPECIFIC PERFORMANCE COMMENCED BY
PURCHASER AGAINST SELLER SHALL BE FILED WITHIN TEN (10) BUSINESS DAYS AFTER THE SCHEDULED CLOSING DATE; PROVIDED, HOWEVER, IF SPECIFIC PERFORMANCE IS NOT AN AVAILABLE REMEDY HEREUNDER, THEN PURCHASERS SOLE REMEDY SHALL BE AS PROVIDED IN
SECTION 13.1(A) ABOVE, EXCEPT THAT IF PURCHASER IS UNABLE TO PURSUE SPECIFIC PERFORMANCE SOLELY BECAUSE OF SELLERS SALE OF THE PROPERTY, THEN IN ADDITION TO RECOVERING FROM THE TITLE COMPANY THE EARNEST MONEY DEPOSIT, PURCHASER
SHALL ALSO BE ENTITLED TO RECOVER FROM SELLER CONTRACT DAMAGES EQUAL TO PURCHASERS ACTUAL, REASONABLE LOSSES AS A RESULT THEREOF, SUBJECT TO SECTION 13.3 BELOW (BUT SUCH DAMAGES WITH RESPECT TO PURCHASERS LOSS OF THE BENEFIT OF
ITS BARGAIN SHALL NOT EXCEED THE NET EXCESS AMOUNT, IF ANY, THAT SELLER WOULD HAVE REALIZED HAD SELLER SOLD THE PROPERTY FOR ITS FAIR MARKET VALUE ON THE CLOSING DATE TO A BONA FIDE THIRD PARTY PURCHASER OVER THE PURCHASE PRICE), WHEREUPON PURCHASER
AND SELLER SHALL HAVE NO FURTHER RIGHTS OR OBLIGATIONS UNDER THIS AGREEMENT EXCEPT WITH RESPECT TO THE TERMINATION SURVIVING OBLIGATIONS.



IN EITHER EVENT, PURCHASER HEREBY WAIVES ALL OTHER REMEDIES FOR A PRE-CLOSING DEFAULT BY SELLER, INCLUDING WITHOUT LIMITATION, ANY CLAIM AGAINST SELLER
FOR DAMAGES (OTHER THAN AS EXPRESSLY PROVIDED HEREINABOVE) OF ANY TYPE OR KIND INCLUDING, WITHOUT LIMITATION, PUNITIVE DAMAGES. FAILURE OF PURCHASER TO MAKE THE FOREGOING ELECTION WITHIN THE FOREGOING TEN (10) BUSINESS DAY PERIOD (OR IF

SELLER AND PURCHASER WILL HAVE NO FURTHER RIGHTS OR OBLIGATIONS UNDER THIS AGREEMENT, EXCEPT WITH RESPECT TO THE TERMINATION SURVIVING OBLIGATIONS.
NOTWITHSTANDING THE FOREGOING, NOTHING CONTAINED IN THIS SECTION 13.1 WILL LIMIT PURCHASERS REMEDIES AT LAW, IN EQUITY OR AS HEREIN PROVIDED IN THE EVENT OF A BREACH BY SELLER OF ANY OF THE CLOSING SURVIVING OBLIGATIONS AFTER
CLOSING OR THE TERMINATION SURVIVING OBLIGATIONS AFTER TERMINATION. NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, PURCHASER SHALL NOT SEEK A PERSONAL JUDGMENT AGAINST SELLER NOR ITS MEMBERS, MANAGERS, EMPLOYEES OR AGENTS, NOR THE SHAREHOLDERS,

Section 13.2
DEFAULT BY PURCHASER. IN THE EVENT THE CLOSING AND THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREIN DO NOT OCCUR AS PROVIDED HEREIN BY REASON OF A DEFAULT BY PURCHASER, PURCHASER AND SELLER AGREE THAT IT WOULD BE IMPRACTICAL AND
EXTREMELY DIFFICULT TO FIX THE DAMAGES WHICH SELLER MAY SUFFER AND THAT THE EARNEST MONEY DEPOSIT, EXCLUSIVE OF ANY INTEREST ACCRUED THEREON, IS A REASONABLE ESTIMATE OF SUCH DAMAGES. THE PARTIES THEREFORE AGREE THAT IN THE EVENT THAT THE CLOSING
AND THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREIN DO NOT OCCUR AS PROVIDED HEREIN SOLELY BY REASON OF ANY DEFAULT OF PURCHASER IN THE PERFORMANCE OF ITS OBLIGATIONS UNDER THIS AGREEMENT, THE EARNEST MONEY DEPOSIT, EXCLUSIVE OF ANY
INTEREST ACCRUED THEREON, WILL BE SELLERS FULL, AGREED AND LIQUIDATED DAMAGES AND WILL BE SELLERS SOLE AND EXCLUSIVE REMEDY (WHETHER AT LAW OR IN EQUITY) IN LIEU OF ANY OTHER DAMAGES, SPECIFIC PERFORMANCE, OR ANY OTHER REMEDY SELLER
MIGHT OTHERWISE HAVE AGAINST PURCHASER, WHEREUPON THIS AGREEMENT WILL TERMINATE AND SELLER AND PURCHASER WILL HAVE NO FURTHER RIGHTS OR OBLIGATIONS HEREUNDER, EXCEPT WITH RESPECT TO THE TERMINATION SURVIVING OBLIGATIONS. THIS SECTION SHALL NOT LIMIT
SELLERS RIGHT TO RECOVER ITS ATTORNEYS FEES ATTRIBUTABLE TO EFFORTS TO OBTAIN THE EARNEST MONEY DEPOSIT OR TO ENFORCE PURCHASERS INDEMNIFICATION OBLIGATIONS, NOR WAIVE OR AFFECT SELLERS RIGHTS AND PURCHASERS INDEMNITY
OBLIGATIONS UNDER OTHER SECTIONS OF THIS AGREEMENT (WHICH ARE NOT LIMITED BY THIS SECTION 13.2). THE PAYMENT OF SUCH AMOUNT AS LIQUIDATED DAMAGES IS NOT INTENDED AS A FORFEITURE OR PENALTY, BUT IS INTENDED TO CONSTITUTE LIQUIDATED
DAMAGES TO SELLER. NOTWITHSTANDING THE FOREGOING, NOTHING CONTAINED HEREIN WILL LIMIT SELLERS REMEDIES AT LAW, IN EQUITY OR AS HEREIN PROVIDED IN THE EVENT OF A BREACH BY PURCHASER OF ANY OF THE TERMINATION SURVIVING OBLIGATIONS. SELLER AND
PURCHASER ACKNOWLEDGE THAT THEY HAVE

ASSIGNMENT AND BINDING EFFECT



Section 15.1 Assignment; Binding Effect. Neither party will have the right to assign this Agreement without the non-assigning
partys prior written consent, which consent may be withheld in such non-assigning partys sole and absolute discretion. Any attempted assignment or delegation in violation of this Section 15.1 without the prior written consent
of the other party hereto shall be void, and the purported assignee shall not have any rights hereunder. Notwithstanding the foregoing, Purchaser and Seller may each assign and delegate its rights and obligations under this Agreement to an Affiliate
of such assigning party without the consent of the non-assigning party, provided that (i) as of the effective date of such assignment, such Affiliate assignee expressly assumes, for the benefit of the non-assigning party, all of the assigning
partys obligations under this Agreement, and (ii) any such assignment shall not relieve the assigning party of its obligations hereunder. Subject to the foregoing, this Agreement will be binding upon and inure to the benefit of Seller and
Purchaser and their respective successors and permitted assigns, and no other party will be conferred any rights by virtue of this Agreement or be entitled to enforce any of the provisions hereof. Whenever a reference is made in this Agreement to
Seller or Purchaser, such reference will include the successors and permitted assigns of such party under this Agreement.

Seller under this Agreement and any and all documents executed pursuant hereto or in connection herewith (including, without limitation, the breach of any representations and warranties of Seller contained in such documents) for which a claim is
timely made by Purchaser shall not exceed three percent of the final Purchase Price. Purchaser will not have any right to bring any action against Seller as a result of any untruth or inaccuracy of such representations and warranties, or any such
breach, unless and until the aggregate amount of all liability and losses arising out of any such untruth or inaccuracy, or any such breach, exceeds Fifty Thousand Dollars ($50,000). Any action, suit or proceeding brought by Purchaser against Seller
arising from or related to this Agreement must be commenced and served, if at all, on or before the date which is nine (9) months after the date scheduled for the Closing Date. This Section 16.1 shall survive the Closing.



ARTICLE XVII.

MISCELLANEOUS



Section 17.1 Waivers. No waiver of any breach of any covenant or provisions contained herein will be deemed a waiver of any preceding
or succeeding breach thereof, or of any other covenant or provision contained herein. No extension of time for performance of any obligation or act will be deemed an extension of the time for performance of any other obligation or act.



Section 17.2 Recovery of Certain Fees. In the event a
party hereto files any action or suit against another party hereto relating to or arising out of this Agreement, the transaction described herein, or the enforcement hereof, then in that event the prevailing party will be entitled to have and
recover of and from the other party all reasonable attorneys fees and costs resulting therefrom. For purposes of this Agreement, the term attorneys fees or attorneys fees and costs shall mean
the fees and expenses of counsel to the parties hereto, which may include printing, photostating, duplicating and other expenses, air freight charges, and fees billed for law clerks, paralegals and other persons not admitted to the bar but
performing services under the supervision of an attorney, and the costs and fees incurred in connection with the enforcement or collection of any judgment obtained in any such proceeding. The provisions of this Section 17.2 shall survive
the entry of any judgment, and shall not merge, or be deemed to have merged, into any judgment.



Section 17.3 Time of Essence. Seller and Purchaser hereby acknowledge and agree that time is strictly of the essence with respect to
each and every term, condition, obligation and provision hereof.



Section 17.4 Construction. Headings at the beginning of each article and section are solely for the convenience of the parties and are not a part of this Agreement. Whenever required by the context of this Agreement, the
singular will include the plural and the masculine will include the feminine and vice versa. This Agreement will not be construed as if it had been

prepared by one of the parties, but rather as if both parties had prepared the same. All exhibits and schedules referred to in this Agreement are attached
and incorporated by this reference, and any capitalized term used in any exhibit or schedule which is not defined in such exhibit or schedule will have the meaning attributable to such term in the body of this Agreement. In the event the date on
which Purchaser or Seller is required to take any action under the terms of this Agreement is not a Business Day, the action will be taken on the next succeeding Business Day.



Section 17.5. Counterparts. To facilitate execution of this Agreement, this Agreement may be executed in
multiple counterparts, each of which, when assembled to include an original signature for each party contemplated to sign this Agreement, will constitute a complete and fully executed original. All such fully executed original counterparts will
collectively constitute a single agreement.



Section 17.6 Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of law or public policy, all of the other conditions and provisions of this
Agreement will nevertheless remain in full force and effect, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any adverse manner to either party. Upon such determination that any term or other
provision is invalid, illegal, or incapable of being enforced, the parties hereto will negotiate in good faith to modify this Agreement so as to reflect the original intent of the parties as closely as possible in an acceptable manner to the end
that the transactions contemplated hereby are fulfilled to the extent possible.



Section 17.7 Entire Agreement. This Agreement is the final expression of, and contains the entire agreement between, the parties with respect to the subject matter hereof, and supersedes all prior
understandings with respect thereto. This Agreement may not be modified, changed, supplemented or terminated, nor may any obligations hereunder be waived, except by written instrument, signed by the party to be charged or by its agent duly
authorized in writing, or as otherwise expressly permitted herein.



Section 17.8 Governing Law. This Agreement and the rights and obligations of the parties hereto shall be governed by and construed and enforced in accordance with the laws of the State of Washington, exclusive of the
conflict of laws principles of such state. The parties consent to jurisdiction of the state courts located in King County, Washington in the event of any litigation arising out of this Agreement.



Section 17.9 Recording. The parties hereto agree that this
Agreement will not be recorded. However, at Purchasers option, a Memorandum of this Agreement will be recorded in King County, Washington, so long as Seller has the right to record a termination of such memorandum, if this Agreement is
terminated, and if Purchaser fails to file a termination of the memorandum within ten (10) days of termination of this Agreement.



Section 17.10 Further Actions. The parties agree to execute such instructions to the Title Company and such other instruments and to do
such further acts as may be reasonably necessary to carry out the provisions of this Agreement.

Section 17.13 No Partnership.
Notwithstanding anything to the contrary contained herein, this Agreement shall not be deemed or construed to make the parties hereto partners or joint venturers, it being the intention of the parties to merely create the relationship of Seller and
Purchaser with respect to the Property to be conveyed as contemplated hereby.



Section 17.14 Limitations on Benefits. It is the explicit intention of Purchaser and Seller that no person or entity other than Purchaser and Seller and their permitted successors and assigns is or
shall be entitled to bring any action to enforce any provision of this Agreement against any of the parties hereto, and the covenants, undertakings and agreements set forth in this Agreement shall be solely for the benefit of, and shall be
enforceable only by, Purchaser and Seller or their respective successors and assigns as permitted hereunder. Nothing contained in this Agreement shall under any circumstances whatsoever be deemed or construed, or be interpreted, as making any third

of this Agreement.
