9. EXTENSION TO PERFECT TITLE OR MAKE PREMISES CONFORM. If the Seller shall be unable to give title or to make conveyance, or to deliver possession of the premises, all as herein stipulated, or if at the time of delivery of the Deed the premises do not conform with the provisions thereof, then the Seller shall use reasonable efforts to remove any defects in title, or to deliver possession as provided herein, or to make the premises conform to the provisions hereof, as the case may be, in which event the time for performance hereof shall be extended for a period of up to thirty (30) days; provided, however, that Seller shall not be obligated to spend more than $10,000 to cure any such defects, exclusive of voluntary liens.

10. FAILURE TO PERFECT TITLE OR MAKE PREMISES CONFORM, ETC.

12. ACCEPTANCE OF DEED. The acceptance and recording of a deed by the Buyer or nominee, as the case may be, shall be deemed to be a full performance and discharge of every agreement and obligation herein contained or expressed, except such as are, by the terms hereof, to be performed after the delivery of said deed except instruments, such as discharges from institutional lenders, which are customarily recorded within a reasonable time after closing, in accordance with the Massachusetts Real Estate Bar Association standards.

13. USE OF MONEY AND CLEAR TITLE. To enable the Seller to make conveyance as herein provided, the Seller may, at the time of delivery of the deed, use all the purchase money or any portion thereof to clear the title of any or all encumbrances or interests, provided that all instruments so procured are recorded simultaneously with the delivery of said deed, or that the usual and customary arrangements are made for the securing and recording of such instruments.

14. ADJUSTMENTS. Taxes, if any, for the then current fiscal year shall be apportioned as of the day of performance of this agreement and the net amount thereof shall be added to or deducted from, as the case may be, the purchase price payable by the Buyer at the time of delivery of the deed. Notwithstanding any term or condition in this Agreement to the contrary, Seller and Buyer hereby acknowledge and agree that the Buyer shall be solely responsible for the payment of any betterment assessments related to the premises which become due and payable after the date of this Agreement regardless of the effective date of such betterment assessment or the fiscal year to which such betterment assessment applies and, to the extent the Seller has paid any portion of such betterment assessment prior to the Closing, the full amount so paid by Seller shall reimbursed to Seller by Buyer at the Closing. The Seller and Buyer hereby acknowledge and agree that the Town of Tyngsborough is or may be contemplating the imposition of a better assessment against the Premises related to sewage, drainage and sidewalks (the “Sewage Betterment Assessment”) and Buyer hereby acknowledges and agrees that if and/or when the Closing occurs, the Buyer shall be solely responsible for any and all costs related to the Sewage Betterment Assessment and any and all connection fees related thereto.

15. ADJUSTMENTS OR UNASSESSED AND ABATED TAXES. With the exception of any betterment assessments related to the premises (which shall be the sole responsibility of the Buyer as described in Section 14 above), taxes for the then current fiscal year shall be apportioned as of the day of performance of this agreement and the net amount thereof shall be added to or deleted from, as the case may be, from the purchase price payable by the Buyer at the time of delivery of the deed. If the amount of said taxes is not known at the time of the delivery of the deed, they shall be apportioned on the basis of the taxes assessed for the preceding year, with a reapportionment as soon as the new tax rate and valuation can be ascertained; and, if the taxes which are to be apportioned shall thereafter be reduced by abatement, the amount of such abatement, less the reasonable cost of obtaining the same, shall be apportioned between the parties, provided that neither party shall be obligated to institute or prosecute proceedings for an abatement unless herein otherwise agreed. Notwithstanding the foregoing, any apportionment must be made within six (6) months following the Closing and in no event shall either party have the right to obtain any amount from the other with respect to apportionment of taxes unless such party has made a written request to the other within such six (6) months following the Closing.

16. BROKER. Seller and Buyer warrant and represent to the other that it has dealt with no real estate agent or broker in connection with this transaction other than Transwestern/RBJ (the “Broker”) and agrees to defend (with counsel reasonably approved by the other), indemnify and hold harmless the other from and against any commission, fee, claim, loss, damage, cost or liability which may be asserted by any real estate agent or broker with which it has dealt in connection with this transaction other than the Broker. Seller hereby acknowledges and agrees that Seller shall be solely responsible for paying the Broker a commission or fee in connection with this transaction pursuant to a separate agreement. Seller and Buyer hereby acknowledge and agree that The Stubblebine Company has been involved in a potential transaction wherein a third party buyer will buy a portion of the premises from Buyer after the Closing. Buyer hereby acknowledges and agrees that Buyer shall be solely responsible for paying any commission or fee of The Stubblebine Company in connection with such transaction with such third party buyer pursuant to a separate agreement. In no event shall Seller be responsible for paying a

4

commission or fee to The Stubblebine Company in connection with this transaction or such proposed transaction with such third party buyer. This paragraph will survive the delivery of the deed.

17. BUYER’S DEFAULT DAMAGES. If the Buyer shall fail to fulfill the Buyer’s agreements herein, all deposits made hereunder by the Buyer shall be retained by Seller as liquidated damages, as Seller’s sole and exclusive remedy at law, in equity or otherwise. The Buyer and Seller agree that in the event of default by the Buyer the amount of damages suffered by the Seller will not be easy to ascertain with certainty and, therefore, Buyer and Seller agree that the amount of the Buyer’s deposits represent a reasonable estimate of the damages likely to be suffered regardless of any future sale of the property.

18. SELLER’S DEFAULT DAMAGES. If Seller shall default in the performance of its closing obligations under this Agreement, or if the Closing shall fail to occur as a result of the Seller’s inability to deliver good, clear, marketable title or comply with the provisions of Paragraph 8 of this Agreement, then upon written notice of such default from Buyer to Seller and Escrow Agent, the Escrow Agent shall deliver all non-refundable Deposits plus all accrued interest thereon to Buyer, and notwithstanding the same, the Buyer shall be entitled to exercise any and all rights and remedies available to Buyer at law and in equity, including, without limitation, the right to commence an action for specific performance of this Agreement.

19. LIABILITY OF TRUSTEE, BENEFICIARY, ETC. If the Seller or Buyer executes this agreement in a representative or fiduciary capacity, only the entity represented shall be bound, and neither the Seller or Buyer so executing, nor any shareholder or beneficiary or any trust, shall be personally liable for any obligation, express or implied, hereunder.

20. SELLER’S REPRESENTATIONS: Subject to Sections 21 and 22 below, Seller hereby covenants, as of the date hereof and at the time of the closing, the following, each of which shall constitute and be determined as a condition of this Agreement:

Seller and Buyer agree that Seller’s Representations set forth in Section 20 above and any other obligations of Seller which survive the Closing, shall survive Closing for a period of six (6) months (the “Survival Period”). Seller shall have no liability after the Survival Period with respect to Seller’s Representations set forth in Section 20 above or for any of Seller’s obligations which survive the Closing except to the extent that Buyer has delivered notice to Seller during the Survival Period and commenced litigation against Seller by filing and serving a lawsuit within thirty (30) days

In the event that Seller breaches any representation contained in Section 20 and the Buyer had actual knowledge of such breach prior to the Closing, and elected to close regardless, Buyer shall be deemed to have waived any right of recovery, and Seller shall not have any liability in connection therewith.

22. LIQUIDATION AND DISSOLUTION OF SELLER. Buyer acknowledges that Seller filed a certificate of dissolution with the Secretary of State of the State of Delaware pursuant to §275 of the Delaware General Corporation Law (the “DGCL”) on March 7, 2013 and that in connection therewith Seller is in the process of liquidating its assets and intends to distribute any excess cash to Seller’s stockholders as promptly as practicable in accordance with the DGCL.
