Indemnified Party may participate in the defense of any claim with counsel of its own choice and at its own expense. The parties agree to cooperate fully with each other in connection with the defense, negotiation or settlement of any such claim. In
the event that the Indemnifying Party does not undertake the defense, compromise or settlement of a claim, the Indemnified Party shall have the right to control the defense or settlement of such Claim with counsel of its choosing provided, however,
that the Indemnified Party shall not settle or compromise any such claim without the Indemnifying Party’s prior written consent, which consent shall not be unreasonably withheld. 

  

 121 

	 	F.	Exclusive Remedy. The indemnification provided pursuant to this Article VIII shall be the sole and exclusive remedy for any claims for indemnification
with respect to breaches of representation and warranty in this Agreement and in each Transaction Document. 

  

	IX.	TRANSACTION COSTS 

  

	 	A.	Transaction Costs. Each party shall be responsible for its own costs and expenses incurred in connection with the preparation, negotiation and consummation of
this Agreement and the Transaction Documents, including but not limited to attorney and other professional fees. 

  

	 	B.	Brokerage. The parties hereby expressly warrant and represent that neither party has any liability for payment to any broker, agent, or finder in connection with
the transactions contemplated under this Agreement and shall indemnify and hold harmless the other party hereto for such payments. 

  

	X.	TERMINATION 

  

	 	A.	Termination Rights. This Agreement may be terminated by written notice before Closing: 

  

	 	1.	by Buyer if any condition set forth in Section VIII(B) is not satisfied at the time scheduled for Closing or if the satisfaction of any such condition is or
becomes impossible, or 

  

	 	2.	by Seller if any condition set forth in Section VIII(C) is not satisfied at the time scheduled for Closing or if the satisfaction of any such condition is or
becomes impossible; 

  

	 	3.	by either party in the event the Closing does not occur, for any reason, prior to November 30, 2008. 

  

	 	B.	Effect of Termination. In the event this Agreement is terminated by Buyer, then Buyer shall return any Products received from Seller pursuant to this Agreement
prior to or following such termination. 

  

	XI.	Non-Competition 

 In order
to induce Buyer to make the acquisitions set forth in this Agreement, Principal, a principal of the Seller, and Seller agreed to enter into a non-competition arrangement with the Buyer. Accordingly, Principal and Seller hereby agree that for the
period of three years from and after the Closing Date, neither of them shall, anywhere within the United States of America (or for such lesser area or such lesser period as may be determined by a court of competent jurisdiction to be a reasonable
limitation on the competitive activity of the Seller or Principal), directly or indirectly: (a) engage in the manufacturing, marketing, distribution, or sale of the Products or of products substantially similar to the Products,
(b) solicit, or attempt to solicit, business in connection with the foregoing from any parties who are customers of Buyer, (c) otherwise divert, or attempt to divert from Buyer any business relating to the Products or of products
substantially similar to the Products; or (d) render any service as a joint venturer, partner, consultant, or otherwise to, or have any interest as a stockholder, partner, member, lender, or otherwise in, any person or entity that is engaged in
activities which, if performed by Seller or Principal would violate this Article XI; provided, however, that the foregoing shall not prevent Seller or Principal from purchasing or owning up to 5% of the voting securities or interests of any
corporation, the securities of which are publicly-traded. In addition to the proscription against competition with Buyer as set forth herein, Seller also agrees that it will not dispose of any equipment or inventory Seller retains to any entitly
which is engaged in the manufacturing, marketing, distribution, or sale of the Products or of products substantially similar to the Products. Because Buyer would not have adequate remedies at law to protect its business from any breach of the
foregoing, Buyer shall be entitled to injunctive relief in the event of such a breach or threatened breach thereof by Seller or Principal, and, in

  

 122 

 
the event of such breach, in addition to any other remedies, Buyer shall be entitled to receive from Seller and/or Principal, payment of, or reimbursement for, its reasonable attorney’s fees
and disbursements incurred in successfully enforcing any of the foregoing. 
  

	XII.	MISCELLANEOUS 

  

	 	A.	Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement, and shall become effective
when one or more counterparts have been signed by each of the Parties and delivered to the other party.

	 	C.	Amendments and Waivers. No provisions of this Agreement shall be deemed waived, amended, supplemented or modified by any party, unless such waiver, amendment,
supplement or modification is in writing and signed by the authorized representative of the party against whom it is sought to be enforced. 

  

	 	D.	Governing Law. This Agreement shall be governed by and construed and interpreted in accordance with the laws of the State of Florida, irrespective of its choice
of laws principles, as to all matters, including matters of validity, construction, effect, enforceability, performance and remedies, and, to the extent applicable, the federal laws of the United States. Any action brought by Seller, Buyer, or
Principal in connection with this Agreement shall be brought in a court of appropriate jurisdiction located within Pinellas County, Florida, and Seller, Buyer, and Principal hereby agree to such venue and subject themselves to the jurisdiction of
the courts of Pinellas County, Florida. 

  

	 	E.	Assignability. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and thereto, respectively, and their respective successors and
assigns. No party may assign its respective rights or delegate its respective obligations under this Agreement without the express prior written consent of the other party, which consent shall not be unreasonably withheld. 

 

	 	F.	Third Party Beneficiaries. Except as expressly set forth herein, there are no third party beneficiaries of this Agreement, and the provisions of this Agreement
are solely for the benefit of the parties and are not intended to confer any rights or remedies to any person which is not a party to this Agreement. 

  

	 	G.	Notices. All notices and other communications hereunder shall be in writing and shall be deemed duly given (a) on the date of delivery if delivered

 Attention: Chief Executive Officer

 123 

 Any party may, by notice to the other party given in the form specified above, change the
address to which such notices are to be given. 
  

	 	H.	Severability. If any provision of this Agreement is determined by a court of competent jurisdiction to be invalid, void or unenforceable, the remaining
provisions hereof shall remain in full force and effect and shall in no way be affected, impaired or invalidated thereby, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner adverse to any
party and the parties shall negotiate in good faith in an effort to agree upon a suitable and equitable means to effect the original intent of the parties. 

  

	 	I.	Force Majeure. No party shall be deemed in default of this Agreement to the extent that any delay or failure in the performance of its obligations under this
Agreement results from any cause beyond its reasonable control and without its fault or negligence, such as acts of God, acts of civil or military authority, acts of terrorism, embargoes, epidemics, war, riots, insurrections, fires, explosions,
earthquakes, floods, unusually severe weather conditions, labor problems or unavailability of parts, or, in the case of computer systems, any failure in electrical or air conditioning equipment. In the event of any such excused delay, the time for
performance shall be extended for a period equal to the time lost by reason of the delay. 

  

	 	J.	Headings. The article, section and paragraph headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. 

  

	 	K.	Schedules and Appendices. All schedules and appendices referenced in this Agreement and attached hereto are incorporated herein by reference and shall be
considered for all purposes as part of this Agreement. 

  

	 	L.	Remedies. The Parties acknowledge that the legal remedy for breach by any of them of their respective obligations hereunder may be inadequate and, therefore, in
the event of any actual or threatened breach of any such obligation, such parties agree that, in addition to any other available remedy, such obligation may be specifically enforced against them. 

  

	 	M.	Waivers of Default. Waiver by either party of any default by the other party of any provision of this Agreement shall not be deemed a waiver by the waiving party
of any subsequent or other default, nor shall it prejudice the rights of the other party. 

  

	 	N.	Public Announcements. Neither party shall issue any press release or other public announcement concerning the transactions contemplated by this agreement without
the prior written consent of both the Seller and Buyer, which consent shall not be unreasonably withheld. Notwithstanding the foregoing, either party may make any required filings and disclosures pursuant to any applicable rules or requirements of
the United States Securities and Exchange Commission, or any other regulatory agency, or any exchange, without the prior written consent of the other party. 

  

	 	O.	Facsimile Signatures. The parties agree that this Agreement may be delivered by use of a facsimile machine and the signatures and initials shall be deemed to be
valid and binding upon the parties as if the original signatures and initials were present on the documents in the handwriting of each party. Neither party shall assert the Statute of Frauds or non-enforceability or invalidity of the Agreement
because of facsimile copies being used, and all parties specifically waive and relinquish any such defense. Each party agrees to provide an original signed document to the other upon request.
