Agreement or any other information or data obtained by Buyer reflects the existence of any encumbrance,
encroachment, defect in or objection to title, other than those set forth in Exhibit A, that render title to the Properties
or any portion of the Properties defective or encumbered, such that the Properties or any portion of the Properties are
not capable of being conveyed due to a title defect or objection that would make the Properties unmerchantable
(“Title Defects”):

       (a) Buyer shall notify Seller of the Title Defects, as they are identified, but in any event within 10
days following execution of this Agreement, and providing Seller adequate information to enable Seller to go
forward with curing the Title Defects. Within 10 days prior to Closing, Seller shall furnish Buyer all documentation
satisfying the Title Defects.

       (b) If Seller is unable to cure the Title Defect, Buyer shall have the option to: remove the Properties
on which there are Title Defects from the transaction contemplated by this Agreement and reduce the Purchase Price
accordingly in a mutually agreeable amount; or, accept the Properties with the Title Defects and adjust the Purchase
Price in an amount agreed upon by Buyer and Seller. If Buyer and Seller cannot reach an agreement on an
adjustment to the Purchase Price, Buyer shall have the further option to remove the Properties or accept the
Properties with no adjustment in the Purchase Price.

       (c) The value of Title Defects not constituting a breach of any of Seller’s representations or warranties
must exceed $25,000.00 in value before any adjustment to the Purchase Price will be made. Upon the determination
that all such Title Defects total in excess of $25,000.00 in value, all identified Title Defects may give rise to a
Purchase Price adjustment. Notwithstanding this limitation, Buyer always shall have the option to remove from this
transaction any Properties on which there are Title Defects, regardless of the value assigned to the Title Defects and
affected Properties.

(d) Casualty Loss. If, prior to Closing, all or any portion of the Properties shall be destroyed by fire
or other casualty, or if any portion of the Properties shall be taken in condemnation or under the right of eminent
domain, or, if proceedings for such purposes shall be pending or threatened, Buyer may elect to terminate this
Agreement. If Buyer makes this election, neither party shall have any further obligation to the other under or by this
Agreement, except such obligations which, by their terms, survive termination of this Agreement. If not so
terminated, this Agreement shall remain in full force and effect notwithstanding any such destruction or taking, and
Seller shall, at Closing, pay to Buyer all sums (such as insurance proceeds) paid to Seller by reason of such
destruction or taking. In addition, Seller shall assign, transfer and set over to Buyer all of the right, title and interest
of Seller in and to any unpaid awards or other payments arising out of such destruction or taking. Seller shall not
voluntarily compromise, settle or adjust any amounts payable by reason of such destruction or taking without first
obtaining the written consent of Buyer.

8. Physical and Environmental Inspection. After the execution of this Agreement, Buyer and its authorized
representative shall have physical access to the Interests at Buyer’s sole cost, risk and expense for the purpose of
inspecting the Interests as may be reasonably necessary and appropriate, in Buyer’s sole judgment, to evaluate the
physical and environmental condition of the Interests, including the identification of wetlands. Buyer shall defend
and indemnify Seller from any and all liability, claims, causes of action, injury to Buyer’s employees, agents or
contractors or to Seller’s property which may arise out of Buyer’s inspections, but only to the extent of Buyer’s
negligence. Buyer agrees to provide Seller, upon reasonable request, a copy of any environmental assessments
including any reports, data and conclusions. Except as otherwise provided by law or regulation, Buyer and Seller
shall keep any and all such data or information obtained or determined during such inspections and the results of any
analysis strictly confidential and shall not disclose same to any person or agency without the prior written approval
of both Buyer and Seller. The foregoing obligation of confidentiality shall survive the Closing or termination of this
Agreement.

9. Due Diligence Period. During the due diligence period, Buyer shall complete its physical and
environmental inspections and such other due diligence as it deems reasonably necessary, in its sole judgment, prior
to Closing.
