Loss 
 10.1 Risk of Loss. Until Closing has occurred, the risk of loss or damage to the Property or any portion thereof
shall be assumed by Seller who will promptly notify Purchaser in writing as to the occurrence, extent and estimated cost of repair of the damage. In the event of any material damage to the Property by fire or other casualty, act of God or any other
event, either Seller or Purchaser shall have the right, exercisable by written notice to the other prior to Closing, to (a) terminate this Agreement, in which event, Purchaser shall obtain a refund of its Deposit; or (b) close, in which
event, the insurance proceeds as well as the applicable deductible amount and any unpaid claims or rights in connection with such casualty, shall be deposited into an escrow account at Closing pursuant to an escrow agreement which will require

effect, and Seller shall at Closing assign to Purchaser all rights of Seller to the condemnation award, less all costs and expenses incurred by Seller in restoring the damage to the Property in connection therewith, but there shall be no reduction
in the Purchase Price. For purposes hereof, a taking shall be deemed to be material if the taking would cause the Property to be in violation of applicable laws or more than 10% of the area of the Land is taken. If the taking is not material for
purposes hereof, Purchaser shall have no right to terminate this Agreement as a result of the taking. If Closing occurs, the PBSJ Lease shall be modified to provide for the restoration of any damage to the Property following Closing and the

liabilities to any other party. The foregoing shall not limit or affect any remedies of Seller with respect to obligations of Purchaser which survive the termination or Closing of this Agreement.

Deposit, or (ii) enforce specific performance of this Agreement, or (iii) proceed to Closing, thereby waiving the breach; provided, that if Purchaser tenders the Purchase Price at the Closing, Seller defaults by failing to convey the
Property to Purchaser at Closing as required hereunder and the remedy of specific performance is not available because Seller has conveyed the Property to another party, Purchaser shall be entitled to seek to recover Purchaser’s actual (but not
consequential, speculative or punitive damages) caused by Seller’s default. Seller acknowledges and agrees that the remedy of specific performance is an appropriate remedy as provided for hereunder.

 14.2 Governing Law. This Agreement shall be governed by and construed in accordance
with the laws of the State of Florida. 
 14.3 Headings. The captions and headings herein are for convenience and reference
only and in no way define or limit the scope or content of this Agreement or in any way affect its provisions. 
 14.4 Effective
Date. This Agreement shall be effective upon delivery of this Agreement fully executed by the Seller and Purchaser, which date shall be deemed the Effective Date hereof (the “Effective Date”). Either party may request that
the other party promptly execute a memorandum specifying the Effective Date hereof. 
 14.5 Business Days. If any date herein
set forth for the performance of any obligations of Seller or Purchaser or for the delivery of any instrument or notice as herein provided should be on a Saturday, Sunday or legal holiday, the compliance with such obligations or delivery shall be
deemed acceptable on the next business day following such Saturday, Sunday or legal holiday. As used herein, the term “legal holiday” means any state or Federal holiday for which financial institutions or post offices are generally
closed in the state where the Property is located. 
 14.6 Counterpart Copies. This Agreement may be executed in two
(2) or more counterpart copies, all of which counterparts shall have the same force and effect as if all parties hereto had executed a single copy of this Agreement. 
 14.7 Binding Effect. This Agreement shall be binding upon, and inure to the benefit of, the parties hereto and their respective successors and assigns. 
 14.8 Assignment. Purchaser shall have the absolute right to assign its rights and interests in the Agreement without the consent of Seller
only (i) to an entity or individual(s) controlled by Purchaser (which for purposes hereof shall mean ownership and the right to vote more than 50% of the outstanding voting interests in such entity), and/or (ii) to effect a tax free
exchange as set forth in Section 14.19 hereof. Except as provided in the preceding sentence or as provided in Section 14.19, this Agreement may not be assigned by Seller or Purchaser. 
  

 -11- 

 14.9 Interpretation. This Agreement shall not be construed more strictly against one party
than against the other merely by virtue of the fact that it may have been prepared by counsel for one of the parties, it being recognized that both Seller and Purchaser have contributed substantially and materially to the preparation of this
Agreement. 
 14.10 Entire Agreement. This Agreement and the Exhibits attached hereto contain the final and entire agreement
between the parties hereto with respect to the sale and purchase of the Property and are intended to be an integration of all prior negotiations and understandings. Purchaser, Seller and their agents shall not be bound by any terms, conditions,
statements, warranties or representations, oral or written, not contained herein. No change or modifications to this Agreement shall be valid unless the same is in writing and signed by the parties hereto. Purchaser and Seller each reserve the right
to waive any of the terms or conditions of this Agreement which are for such waiving party’s benefit and, in the case of Purchaser, to purchase the Property in accordance with the terms and conditions of this Agreement which have not been so
waived. Any such waiver must be in writing signed by the party waiving such term or condition. 
 14.11 Severability. If any
one or more of the provisions hereof shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision hereof, and this Agreement shall be
construed as if such invalid, illegal or unenforceable provision had never been contained herein. 
 14.12 Survival. The
provisions of this Agreement shall survive after the conveyance of title and payment of the Purchase Price for a period of nine (9) months after Closing and shall not be merged therein. 
 14.13 Agreement Not to Market. Seller shall not market the Property or any interest therein, or solicit or accept any offers for the sale
of the Property after the Effective Date, unless this Agreement is terminated in accordance with the terms hereof. 
 14.14 Limitation
of Liability. In no event shall any member, officer, director, partner, shareholder, agent or employee of Purchaser or Seller, or their respective partners or members be personally liable for any of the obligations of Purchaser or Seller, as
the case may be, under this Agreement or otherwise. In addition, and notwithstanding any provision contained in this Agreement or any of the documents to be executed by Seller to Purchaser at Closing (collectively, the “Purchase
Documents”): (i) the representations, warranties, indemnities, undertakings, covenants and agreements of Seller (collectively, “Seller’s Undertakings”) under the Purchase Documents shall not constitute
personal obligations of the officers, directors, employees, agents, trustees, partners, members, representatives, stockholders or other principals or representatives of Seller, and no personal liability or personal responsibility of any sort with
respect to any of Seller’s Undertakings or any alleged breach thereof is assumed by, or shall at any time be asserted or enforceable against any of the officers, directors, employees, agents, trustees, partners, members, representatives,
stockholders or other principals or representatives of Seller; (ii) the period of limitations with respect to Seller’s Undertakings shall expire upon the date which is 270 days following the date of Closing; (iii) in no event shall
Purchaser be entitled to recover any consequential, punitive or speculative damages or lost profits as a result of or in connection with any of Seller’s Undertakings, it being agreed and understood that any action by Purchaser against Seller in
connection with Seller’s Undertakings shall be limited to actual, direct damages incurred by Purchaser in connection therewith, as limited by clause (iv) below; and (iv) Seller’s liability for any and all of Seller’s
Undertakings shall be limited to $220,000.00 in the aggregate with respect to a breach of Seller’s Undertakings as to which Purchaser notifies Seller within 270 days following the Closing, which notice must describe the nature and extent of the
breach and the measures necessary to cure same, and $1,000.00 with respect to any other breach of Seller’s Undertakings, and Seller shall have no liability in excess of such amounts. 
  

 -12- 

 14.15 Waiver of Trial by Jury. The respective parties hereto shall and they hereby do waive
trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other (except for personal injury or property damage) on any matters whatsoever arising out of or in any way connected with this Agreement,
or for the enforcement of any remedy under any statute, emergency or otherwise. 
 14.16 Prevailing Party. Should either party
employ an attorney to enforce any of the provisions hereof, (whether before or after Closing, and including any claims or actions involving amounts held in escrow) or to recover damages for the breach of this Agreement, the non-prevailing party in
any final judgment agrees to pay the other party’s reasonable expenses, including reasonable attorneys’ fees and expenses in or out of litigation and, if in litigation, trial, appellate, bankruptcy or other proceedings, expended or
incurred in connection therewith, as determined by a court of competent jurisdiction. 
 14.17 Indemnification. Seller shall
indemnify, defend and hold Purchaser harmless from all loss, cost, liability and expense (including attorneys’ fees) relating to or arising from any tort claims arising in connection with the ownership or operation of the Property prior to
Closing. 
 14.18 Time is of the Essence. Time is of the essence with respect to each of Seller’s and Purchaser’s
obligations under this Agreement. 
 14.19 Tax-Free Exchange. Seller and Purchaser each hereby reserve the right to effect a
purchase of the Property as part of an exchange transaction (which exchange may be either simultaneous or non-simultaneous with Closing hereunder, and may include a so-called “forward exchange”) that will qualify for treatment under
Section 1031 of the Internal Revenue Code of 1986. Seller and Purchaser agree to cooperate with the other in accomplishing such a Code Section 1031 exchange, provided that neither party shall be obligated to (i) take title to any
exchange property, or (ii) incur any costs or liabilities other than those that would have been incurred by the cooperating party in connection with a direct purchase of the Property on the terms set forth herein. Subject to the foregoing,
Seller and Purchaser each agree to take all actions and execute any and all additional documents reasonably required to effect such a Code Section 1031 exchange. 
 14.20 Condition of Property. Purchaser acknowledges that prior to Closing, Purchaser will have independently and personally inspected the Property and that Purchaser has entered into this Agreement based
upon its ability to make such examination and inspection. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT TO THE CONTRARY, PURCHASER, ACKNOWLEDGES THAT PURCHASER IS PURCHASING THE PROPERTY IN “AS-IS, WHERE-IS” CONDITION “WITH
ALL FAULTS” AS OF THE CLOSING AND SPECIFICALLY AND EXPRESSLY WITHOUT ANY WARRANTIES, REPRESENTATIONS OR GUARANTEES, EITHER EXPRESS OR IMPLIED, FROM ANY OF SELLER AS TO, AND PURCHASER, ON BEHALF OF ITSELF AND ITS SUCCESSORS AND ASSIGNS,
INCLUDING WITHOUT LIMITATION, ANY SUBSEQUENT OWNER OF THE PROPERTY OR ANY PORTION THEREOF, WAIVES ALL CLAIMS AGAINST AND RIGHT TO RECOVER FROM, RELEASES AND AGREES TO INDEMNIFY, DEFEND AND HOLD HARMLESS SELLER FROM ANY AND ALL PRESENT OR FUTURE
DEMANDS, CLAIMS, LEGAL OR ADMINISTRATIVE PROCEEDINGS, LOSSES, LIABILITIES, DAMAGES, PENALTIES, FINES, LIENS, JUDGMENTS, COSTS OR EXPENSES, KNOWN OR UNKNOWN, FORESEEN OR UNFORESEEN, ARISING FROM OR RELATING TO: (I) THE PROPERTY’S CONDITION,
FITNESS FOR ANY PARTICULAR PURPOSES, SUITABILITY, OR MERCHANTABILITY, (II) THE STRUCTURAL INTEGRITY OF AND/OR ANY DEFECTS IN THE IMPROVEMENTS OR THE PROPERTY, (III) THE ACCURACY OR COMPLETENESS OF ANY OF THE INFORMATION, DATA, MATERIALS OR
CONCLUSIONS CONTAINED IN ANY INFORMATION PROVIDED PURCHASER, (IV) THE FAILURE OF THE PROPERTY TO COMPLY WITH ANY LAWS APPLICABLE TO THE PROPERTY, (V) ANY ENVIRONMENTAL CONDITION OF THE PROPERTY, INCLUDING, WITHOUT LIMITATION, THE PRESENCE OR
ALLEGED PRESENCE OF ASBESTOS, RADON OR ANY HAZARDOUS MATERIALS OR HARMFUL OR TOXIC SUBSTANCES IN, ON, UNDER OR ABOUT THE PROPERTY, INCLUDING 

  

 -13- 

 
WITHOUT LIMITATION ANY CLAIMS UNDER OR ON ACCOUNT OF (A) THE COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION AND LIABILITY ACT OF 1980, AS THE SAME
MAY HAVE BEEN OR MAY BE AMENDED FROM TIME TO TIME, AND SIMILAR STATE STATUTES, AND ANY REGULATIONS PROMULGATED THEREUNDER, (B) ANY OTHER FEDERAL, STATE OR LOCAL LAW, ORDINANCE, RULE OR REGULATION, NOW OR HEREAFTER IN EFFECT, THAT DEALS WITH OR
OTHERWISE IN ANY MANNER RELATES TO, ENVIRONMENTAL MATTERS OF ANY KIND, (C) THIS AGREEMENT, OR (D) THE COMMON LAW, OR (VI) ANY OTHER WARRANTY OF ANY KIND, NATURE, OR TYPE WHATSOEVER. PURCHASER SHALL, AT ITS SOLE COST AND EXPENSE, CONDUCT
AND RELY EXCLUSIVELY UPON ITS OWN INDEPENDENT INVESTIGATION IN THE EVALUATION OF THE PROPERTY. IF PURCHASER ACQUIRES THE PROPERTY, PURCHASER ASSUMES ALL RISKS RELATING IN ANY MANNER TO THE PROPERTY OR ANY DEFECTS THEREIN, IF ANY, OF ANY TYPE OR
NATURE WHATSOEVER, AND SHALL BE SOLELY AND COMPLETELY RESPONSIBLE FOR THE PAYMENT OF ALL COSTS AND EXPENSES IN CONNECTION THEREWITH. The provisions of this paragraph shall survive any termination of or Closing under this Agreement, and, at
Seller’s option, shall be set forth in a separate agreement to be executed and delivered by Seller and Purchaser at Closing. 
 14.21
No Recordation. Purchaser agrees that neither this Agreement nor any memorandum or affidavit thereof shall be recorded of public record in any public records. Without limiting the foregoing, Purchaser acknowledges and agrees that it shall
not have the right to file a notice of lis pendens or similar document against the Property in connection with any legal action against Purchaser, or record any other instrument that could impair Seller’s title to the Property, unless
(i) Purchaser has substantially performed all of its obligations and tendered the Purchase Price on the Closing Date pursuant to the terms of this Agreement; (ii) Seller has then defaulted in its obligation to close the transaction
contemplated herein; and (iii) Purchaser has initiated its remedy of specific performance pursuant to Section 12.2 of this Agreement. Should Purchaser ever record or attempt to record this Agreement or a memorandum or affidavit thereof or
a notice of lis pendens or any other similar document other than as permitted pursuant to the preceding sentence, then, notwithstanding anything herein to the contrary, said recordation or attempt at recordation shall constitute a default by
Purchaser hereunder, and, in addition to the other remedies provided for herein, Seller shall have the express right to terminate this Agreement and file a release of such memorandum, lis pendens or other instrument recorded by Purchaser in the
county in which the land is located, which such release shall be effective without Purchaser’s execution or approval thereof, in which event, the entire Deposit shall be retained by Seller. 
 14.22 Radon Gas Disclosure. Florida law requires the following disclosure to be given to the purchaser of property in the State of Florida.
Seller has made no independent inspection of the Property to determine the presence of conditions which may result in radon gas; however, Seller is not aware of any such condition. Certain building methods and materials have been proven to reduce
the possibility of radon gas entering the building: 
 “RADON GAS: Radon is a naturally occurring radioactive gas that, when it has
accumulated in a building in sufficient quantities, may present health risks to persons who are exposed over time. Levels of radon that exceed federal and state guidelines have been found in buildings in Florida. Additional information regarding
radon and radon testing may be obtained from your county public health unit.”
