Amendment to Offer Letter between the Company and Mary Elizabeth Potthoff

 Exhibit 10.5 
 AMENDMENT TO OFFER LETTER 
 This Amendment (the “Amendment”), effective as of
October 31, 2006 (the “Effective Date”), to the offer letter dated July 25, 2002 (the “Offer Letter”) by and between Curis, Inc., a Delaware corporation (the “Company”), and Mary Elizabeth Potthoff (the
“Executive”). 
 WHEREAS, the Company and the Executive desire to amend the Offer Letter to reflect changes which the
parties hereby agree to in connection with the Company’s continued employment of the Executive; and 
 WHEREAS, it is essential
to the Company to retain and attract as executive officers the most capable persons available; and 
 WHEREAS, the substantial
increase in corporate litigation subjects directors and officers to expensive litigation risks at the same time that the availability of directors’ and officers’ liability insurance has been severely limited; and 
 WHEREAS, it is now and has always been the express policy of the Company to indemnify its directors and officers; and 
 WHEREAS, the Executive does not regard the protection available under the Company’s Certificate of Incorporation and insurance as adequate in
the present circumstances, and may not be willing to continue to serve as an executive officer of the Company without adequate protection; and 
 WHEREAS, the Company desires the Executive to continue to serve as an executive officer of the Company. 
 NOW,
THEREFORE, in consideration of the mutual covenants and agreements set forth herein and for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 
  

	1.	Amendments - The Offer Letter shall be amended to include the following provisions. 

  

	 	1.1	At-Will Employment. This Amendment shall not be construed as an agreement, either express or implied, to employ the Executive for any stated term, and shall in no way alter
the Company’s policy of employment at will, under which both the Executive and the Company remain free to terminate the employment relationship, with or without cause, at any time, with or without notice. 

  

	 	1.2	Termination and Severance. The benefits provided for the Executive under this Amendment shall be reduced by the salary continuation payments provided under the Offer Letter.
It is not intended that the Offer Letter provide any benefits in addition to or duplicative of any benefits which the Executive is eligible to receive under this Amendment. This Amendment shall supersede any and all other prior agreements or
arrangements for post-termination benefits and indemnification. 

	 	(a)	In the event the Executive’s employment terminates by the Company for Cause, by the Executive without Good Reason or due to the death or Disability of the Executive, the
Company shall pay to the Executive only her base salary accrued through the last day of her employment with the Company. For the purposes of this Amendment, “Disability” shall be deemed to have occurred when the Employee shall have been
unable to perform her duties by reason of illness or incapacity for a period of 120 consecutive days in any period of 52 consecutive weeks, as determined in good faith by the Company’s Board of Directors (the “Board”) in accordance
with applicable law. 

  

	 	(b)	In the event the Executive’s employment terminates as a result of a voluntary termination by the Executive for Good Reason, or a termination by the Company without Cause, upon
execution of an general release of all claims against the Company, its employees, officers, directors and agents, in a form drafted by the Company, the Executive shall: (i) receive her base salary accrued through the last day of her employment
with the Company, (ii) receive payments equal to one-half (1/2) of the Executive’s then base salary, reduced by all applicable taxes and withholdings, over a period of six months in accordance with the Company’s then current
payroll policies and practices and (iii) the Executive’s medical/dental insurance as an Executive of the Company will cease upon termination and the Executive will immediately become eligible for continuation of medical/dental coverage
pursuant to COBRA. Company will pay any difference between the COBRA premium and the amount the Executive would otherwise be responsible for with respect to the medical and dental coverage elected for a period of six (6) months from the date
such termination or as long as the Executive is eligible for COBRA, whichever period is shorter. At the end of this period, the Executive is eligible to continue coverage for the balance of the statutory period under COBRA, provided that the
Executive pays the COBRA premium. 

  

	 	(c)	For purposes of this Amendment, “Good Reason” means that any of the following are undertaken without the Executive’s express written consent: (i) in the
Executive’s title, authority or responsibility; (ii) any reduction in the Executive’s annual cash compensation; or (iii) a relocation of the place of business at which the Executive is principally located to a location more than
fifty (50) miles from the current principal site. 

  

	 	(d)	For purposes of Sections 1.2(a) and (b) of this Amendment, “Cause” means (V) the Executive’s failure or refusal to substantially perform her duties or the
Executive’s continued neglect to perform such duties to the full extent of her abilities for reasons other than death, physical or mental incapacity, (W) a good faith finding by the Company of the Executive’s failure to perform her
duties as assigned to her by the Board or Chief Executive Officer of the Company, (X) a good faith finding by the Company of dishonesty, gross negligence, or misconduct, (Y) conviction 

  

 - 2 - 

	 	  	or the entry of a pleading of nolo contendere to any crime or felony, or (Z) any breach or threatened breach of any confidentiality, non-solicitation, or inventions
agreement with the Company. For purposes of Section 1.2(e) of this Amendment, “Cause” shall have the meaning ascribed to it in Section 8(c)(1)(d) of the Company’s 2000 Stock Incentive Plan, as amended from time to time.

  

	 	(e)	In the event the Executive’s employment terminates as a result of termination of the Executive by the Company or its successor without Cause, or by the Executive for Good
Reason, within twelve (12) months following a Change in Control Event, upon execution by the Executive of a general release of all claims against the Company, its employees, officers, directors and agents, in a form drafted by the Company, the
Executive shall: (i) receive her base salary accrued through the last day of her employment with the Company; (ii) receive payments equal to one-half (1/2) of the Executive’s then base salary, reduced by applicable taxes and
withholdings, which shall be paid over a period of six months in a manner that is in accordance with the Company’s then current payroll policies and practices and (iii) the Executive’s medical/dental insurance as an Executive of the
Company will cease upon termination and the Executive will immediately become eligible for continuation of medical/dental coverage pursuant to COBRA. Company will pay any difference between the COBRA premium and the amount the Executive would
otherwise be responsible for with respect to the medical and dental coverage elected for a period of six (6) months from the date such termination or as long as the Executive is eligible for COBRA, whichever period is shorter. At the end of
this period, the Executive is eligible to continue coverage for the balance of the statutory period under COBRA, provided that the Executive pays the COBRA premium. For purposes of this section, the Executive’s “base salary” shall be
the greater of the amount in effect either immediately prior to the Change in Control Event or the termination date of the Executive’s employment. The benefits provided under this Section 1.2(e) shall be in lieu of any benefits the
Executive would have otherwise been entitled to pursuant to Section 1.2(b) of this Amendment. 

  

	 	(f)	For purposes of this Amendment, a “Change in Control Event” shall mean: 

  

	 	(i)	The acquisition by an individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a “Person”) of beneficial ownership of any
capital stock of the Company if, after such acquisition, such Person beneficially owns (within the meaning of Rule 13d-3 promulgated under the Exchange Act) 50% or more of either (x) the then-outstanding shares of common stock of the Company
(the “Outstanding Company Common Stock”) or (y) the combined voting power of the then-outstanding securities of the Company entitled to vote 

  

 - 3 - 

	 	  	generally in the election of directors (the “Outstanding Company Voting Securities”); provided, however, that for purposes of this subsection (i), the
following acquisitions shall not constitute a Change in Control Event: (A) any acquisition directly from the Company (excluding an acquisition pursuant to the exercise, conversion or exchange of any security exercisable for, convertible into or
exchangeable for common stock or voting securities of the Company, unless the Person exercising, converting or exchanging such security acquired such security directly from the Company or an underwriter or agent of the Company), (B) any
acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company, or (C) any acquisition by any corporation pursuant to a Business Combination (as defined below)
which complies with clauses (x) and (y) of subsection (iii) of this definition; or 

  

	 	(ii)	Such time as the Continuing Directors (as defined below) do not constitute a majority of the Board (or, if applicable, the Board of Directors of a successor corporation to the
Company), where the term “Continuing Director” means at any date a member of the Board (x) who was a member of the Board on the date of the initial adoption of this Amendment by the Board or (y) who was nominated or elected
subsequent to such date by at least a majority of the directors who were Continuing Directors at the time of such nomination or election or whose election to the Board was recommended or endorsed by at least a majority of the directors who were
Continuing Directors at the time of such nomination or election; or 

  

	 	(iii)	The consummation of a merger, consolidation, reorganization, recapitalization or share exchange involving the Company or a sale or other disposition of all or substantially all of
the assets of the Company (a “Business Combination”), unless, immediately following such Business Combination, each of the following two conditions is satisfied: (x) all or substantially all of the individuals and entities who were
the beneficial owners of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of the then-outstanding shares of common
stock and the combined voting power of the then-outstanding securities entitled to vote generally in the election of directors, respectively, of the resulting or acquiring corporation or other form of entity in such Business Combination (which shall
include, without limitation, a corporation which as a result of such transaction owns the Company or substantially all of the Company’s assets either directly or through one or more subsidiaries) (such resulting or 

  

 - 4 - 

	 	  	acquiring corporation or entity is referred to herein as the “Acquiring Corporation”) in substantially the same proportions as their ownership of the Outstanding Company
Common Stock and Outstanding Company Voting Securities, respectively, immediately prior to such Business Combination and (y) no Person (excluding the Acquiring Corporation or any employee benefit plan (or related trust) maintained or sponsored
by the Company or by the Acquiring Corporation) beneficially owns, directly or indirectly, 50% or more of the then-outstanding shares of common stock of the Acquiring Corporation, or of the combined voting power of the then-outstanding securities of
such corporation entitled to vote generally in the election of directors (except to the extent that such ownership existed prior to the Business Combination). 

  

	 	(g)	Notwithstanding any provision of this Amendment to the contrary, if, at the time the Executive’s employment is terminated, the Executive is a “specified employee”
within the meaning of Section 409A(a)(2)(B)(ii) of the Internal Revenue Code and the regulations thereunder, then any payments to be paid or provided to the Executive under this Amendment that constitute “nonqualified deferred
compensation” within the meaning of Section 409A of the Code shall be delayed by a period of six (6) months and all payments that would have been made to the Executive during such six (6) month period shall be made in a lump sum
in the seventh (7th) month following the date of termination. 

  

	 	1.3	No Duty to Seek Employment. The Executive and the Company acknowledge and agree that nothing contained in this Amendment shall be construed as requiring the Executive to seek
or accept alternative or replacement employment in the event of her termination of employment by the Company for any reason, and no payment or benefit payable hereunder shall be conditioned on the Executive’s seeking or accepting such
alternative or replacement employment. 

  

	 	1.4	Indemnification. Upon the later of (1) six years after the date that the Executive shall have ceased to serve as an executive officer of the Company or, at the request
of the Company, as a director, officer, partner, trustee, member, employee or agent of another corporation, partnership, joint venture, trust, limited liability company or other enterprise or (2) the final termination of all Proceedings (as
defined below) pending on the date set forth in clause (1) in respect of which the Executive is granted rights of indemnification or advancement of Expenses (as defined below) hereunder and of any proceeding commenced by the Executive pursuant
to Section 1.4(h) of this Amendment relating thereto, the Company shall provide indemnification to the Executive as follows: 

  

	 	(a)	Indemnification in Third-Party Proceedings. The Company shall indemnify the Executive in accordance with the provisions of this Section 1.4(a) if the Executive was or is
a party to or threatened to be made a party 

  

 - 5 - 

	 	  	to or otherwise involved in any Proceeding (other than a Proceeding by or in the right of the Company to procure a judgment in its favor) by reason of the Executive’s Corporate
Status or by reason of any action alleged to have been taken or omitted in connection therewith, against all Expenses, judgments, fines, penalties and amounts paid in settlement actually and reasonably incurred by or on behalf of the Executive in
connection with such Proceeding, if the Executive acted in good faith and in a manner which the Executive reasonably believed to be in, or not opposed to, the best interests of the Company and, with respect to any criminal Proceeding, had no
reasonable cause to believe that his or her conduct was unlawful. The termination of any Proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption
that the Executive did not act in good faith and in a manner which the Executive reasonably believed to be in, or not opposed to, the best interests of the Company, and, with respect to any criminal Proceeding, had reasonable cause to believe that
his or her conduct was unlawful. 

  

	 	(b)	Indemnification in Proceedings by or in the Right of the Company. The Company shall indemnify the Executive in accordance with the provisions of this Section 1.4(b) if
the Executive was or is a party to or threatened to be made a party to or otherwise involved in any Proceeding by or in the right of the Company to procure a judgment in its favor by reason of the Executive’s Corporate Status (as defined below)
or by reason of any action alleged to have been taken or omitted in connection therewith, against all Expenses and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred by or on behalf of the Executive in
connection with such Proceeding, if the Executive acted in good faith and in a manner which the Executive reasonably believed to be in, or not opposed to, the best interests of the Company, except that no indemnification shall be made under this
Section 1.4(b) in respect of any claim, issue, or matter as to which the Executive shall have been adjudged to be liable to the Company, unless, and only to the extent, that the Court of Chancery of Delaware or the court in which such action or
suit was brought shall determine upon application that, despite the adjudication of such liability but in view of all the circumstances of the case, the Executive is fairly and reasonably entitled to indemnity for such Expenses as the Court of
Chancery or such other court shall deem proper. 

  

	 	(c)	Exceptions to Right of Indemnification. Notwithstanding anything to the contrary in this Amendment, except as set forth in Section 1.4(h), the Company shall not
indemnify the Executive in connection with a Proceeding (or part thereof) initiated by the Executive unless the initiation thereof was approved by the Board of the Company. Notwithstanding anything to the contrary in this Amendment, the Company
shall not indemnify the Executive to the extent the Executive is reimbursed from the proceeds of insurance, and in the event the Company makes any 

  

 - 6 - 

	 	  	indemnification payments to the Executive and the Executive is subsequently reimbursed from the proceeds of insurance, the Executive shall promptly refund such indemnification
payments to the Company to the extent of such insurance reimbursement. 

  

	 	(d)	Indemnification of Expenses of Successful Party. Notwithstanding any other provision of this Amendment, to the extent that the Executive has been successful, on the merits or
otherwise, in defense of any Proceeding or in defense of any claim, issue or matter therein, the Executive shall be indemnified against all Expenses incurred by or on behalf of Executive in connection therewith. Without limiting the foregoing, if
any Proceeding or any claim, issue or matter therein is disposed of, on the merits or otherwise (including a disposition without prejudice), without (i) the disposition being adverse to the Executive, (ii) an adjudication that the
Executive was liable to the Company, (iii) a plea of guilty or nolo contendere by the Executive, (iv) an adjudication that Executive did not act in good faith and in a manner the Executive reasonably believed to be in or not opposed
to the best interests of the Company, and (v) with respect to any criminal proceeding, an adjudication that the Executive had reasonable cause to believe his or her conduct was unlawful, the Executive shall be considered for the purposes hereof
to have been wholly successful with respect thereto. 

  

	 	(e)	Notification and Defense of Claim. As a condition precedent to the Executive’s right to be indemnified, the Executive must notify the Company in writing as soon as
practicable of any Proceeding for which indemnity will or could be sought. With respect to any Proceeding of which the Company is so notified, the Company will be entitled to participate therein at its own expense and/or to assume the defense
thereof at its own expense, with legal counsel reasonably acceptable to the Executive. After notice from the Company to the Executive of its election so to assume such defense, the Company shall not be liable to the Executive for any legal or other
expenses subsequently incurred by the Executive in connection with such Proceeding, other than as provided below in this Section 1.4(e). The Executive shall have the right to employ his or her own counsel in connection with such Proceeding, but
the fees and expenses of such counsel incurred after notice from the Company of its assumption of the defense thereof shall be at the expense of the Executive unless (i) the employment of counsel by the Executive has been authorized by the
Company, (ii) counsel to the Executive shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the Company and the Executive in the conduct of the defense of such Proceeding or
(iii) the Company shall not in fact have employed counsel to assume the defense of such Proceeding, in each of which cases the fees and expenses of counsel for the Executive shall be at the expense of the Company, except as otherwise expressly
provided by this Amendment. The Company shall not be entitled, without 

  

 - 7 - 

	 	  	the consent of the Executive, to assume the defense of any claim brought by or in the right of the Company or as to which counsel for the Executive shall have reasonably made the
conclusion provided for in clause (ii) above. The Company shall not be required to indemnify the Executive under this Amendment for any amounts paid in settlement of any Proceeding effected without its written consent. The Company shall not
settle any Proceeding in any manner which would impose any penalty or limitation on the Executive without the Executive’s written consent. Neither the Company nor the Executive will unreasonably withhold or delay their consent to any proposed
settlement. 

  

	 	(f)	Advancement of Expenses. Subject to the provisions of Section 1.4(g) of this Amendment, in the event that the Company does not assume the defense pursuant to
Section 1.4(e) of this Amendment of any Proceeding of which the Company receives notice under this Amendment, any Expenses incurred by or on behalf of the Executive in defending such Proceeding shall be paid by the Company in advance of the
final disposition of such Proceeding; provided, however, that the payment of such Expenses incurred by or on behalf of the Executive in advance of the final disposition of such Proceeding shall be made only upon receipt of an
undertaking by or on behalf of the Executive to repay all amounts so advanced in the event that it shall ultimately be determined that the Executive is not entitled to be indemnified by the Company as authorized in this Amendment. Such undertaking
shall be accepted without reference to the financial ability of the Executive to make repayment. 

  

	 	(g)	Procedure for Indemnification. In order to obtain indemnification or advancement of Expenses pursuant to Sections 1.4(a), (b), (d) or (f) of this Amendment, the
Executive shall submit to the Company a written request. Any such indemnification or advancement of Expenses shall be made promptly, and in any event within 30 days after receipt by the Company of the written request of the Executive, unless with
respect to requests under Sections 1.4(a), (b) or (f) the Company determines within such 30-day period that the Executive did not meet the applicable standard of conduct set forth in Section 1.4(a) or (b), as the case may be. Such
determination, and any determination that advanced Expenses must be repaid to the Company, shall be made in each instance (i) by a majority vote of the directors of the Company consisting of persons who are not at that time parties to the
Proceeding (“disinterested directors”), whether or not a quorum, (ii) by a committee of disinterested directors designated by a majority vote of disinterested directors, whether or not a quorum, (iii) if there are no
disinterested directors, or if the disinterested directors so direct, by independent legal counsel (who may, to the extent permitted by applicable law, be regular legal counsel to the Company) in a written opinion, or (iv) by the stockholders
of the Company. 

  

 - 8 - 

	 	(h)	Remedies. The right to indemnification or advancement of Expenses as provided by this Amendment shall be enforceable by the Executive in any court of competent jurisdiction.
Unless otherwise required by law, the burden of proving that indemnification is not appropriate shall be on the Company. Neither the failure of the Company to have made a determination prior to the commencement of such action that indemnification is
proper in the circumstances because the Executive has met the applicable standard of conduct, nor an actual determination by the Company pursuant to Section 1.4(g) that the Executive has not met such applicable standard of conduct, shall be a
defense to the action or create a presumption that the Executive has not met the applicable standard of conduct. The Executive’s expenses (of the type described in the definition of “Expenses” below) reasonably incurred in connection
with successfully establishing the Executive’s right to indemnification, in whole or in part, in any such Proceeding shall also be indemnified by the Company. 

  

	 	(i)	Partial Indemnification. If the Executive is entitled under any provision of this Amendment to indemnification by the Company for some or a portion of the Expenses,
judgments, fines, penalties or amounts paid in settlement actually and reasonably incurred by or on behalf of the Executive in connection with any Proceeding but not, however, for the total amount thereof, the Company shall nevertheless indemnify
the Executive for the portion of such Expenses, judgments, fines, penalties or amounts paid in settlement to which the Executive is entitled. 

  

	 	(j)	Subrogation. In the event of any payment under this Amendment, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of the
Executive, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

  

	 	(k)	Indemnification Hereunder Not Exclusive. The indemnification and advancement of Expenses provided by this Amendment shall not be deemed exclusive of any other rights to which
the Executive may be entitled under the Company’s Certification of Incorporation, the By-Laws, any other agreement, any vote of stockholders or disinterested directors, the General Corporation Law of Delaware, any other law (common or
statutory), or otherwise, both as to action in the Executive’s official capacity and as to action in another capacity while holding office for the Company. Nothing contained in this Amendment shall be deemed to prohibit the Company from
purchasing and maintaining insurance, at its expense, to protect itself or the Executive against any expense, liability or loss incurred by it or the Executive in any such capacity, or arising out of the Executive’s status as such, whether or
not the Executive would be indemnified against such expense, liability or loss under this Amendment; provided that the Company shall not be liable under this Amendment to make any payment of amounts otherwise indemnifiable hereunder if and to the
extent that the Executive has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

  

 - 9 - 

	 	(l)	Definitions. As used in this Amendment: 

  

	 	(i)	The term “Proceeding” shall include any threatened, pending or completed action, suit, arbitration, alternative dispute resolution proceeding, administrative hearing or
other proceeding, whether brought by or in the right of the Company or otherwise and whether of a civil, criminal, administrative or investigative nature, and any appeal therefrom. 

  

	 	(ii)	The term “Corporate Status” shall mean the status of a person who is or was a director or officer of the Company, or is or was serving, or has agreed to serve, at the
request of the Company, as a director, officer, partner, trustee, member, employee or agent of another corporation, partnership, joint venture, trust, limited liability company or other enterprise. 

  

	 	(iii)	The term “Expenses” shall include, without limitation, attorneys’ fees, retainers, court costs, transcript costs, fees and expenses of experts, travel expenses,
duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees and other disbursements or expenses of the types customarily incurred in connection with investigations, judicial or administrative proceedings or
appeals, but shall not include the amount of judgments, fines or penalties against the Executive or amounts paid in settlement in connection with such matters. 

  

	 	(iv)	References to “other enterprise” shall include employee benefit plans; references to “fines” shall include any excise tax assessed with respect to any employee
benefit plan; references to “serving at the request of the Company” shall include any service as a director, officer, employee or agent of the Company which imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interests of the participants and beneficiaries of an employee
benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this Amendment. 

  

	 	(m)	Savings Clause. If this Section 1.4 or any portion thereof shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless
indemnify the Executive as to Expenses, judgments, fines, penalties and amounts paid in settlement with respect to any Proceeding to the full extent permitted by any applicable portion of this Section 1.4 that shall not have been invalidated
and to the fullest extent permitted by applicable law. 

  

 - 10 - 

	 	(n)	Applicable Law. Notwithstanding anything herein to the contrary, this Section 1.4 shall be governed by, and construed and enforced in accordance with, the laws of the
State of Delaware. The Executive may elect to have the right to indemnification or reimbursement or advancement of Expenses interpreted on the basis of the applicable law in effect at the time of the occurrence of the event or events giving rise to
the applicable Proceeding, to the extent permitted by law, or on the basis of the applicable law in effect at the time such indemnification or reimbursement or advancement of Expenses is sought. Such election shall be made, by a notice in writing to
the Company, at the time indemnification or reimbursement or advancement of Expenses is sought; provided, however, that if no such notice is given, and if the General Corporation Law of Delaware is amended, or other Delaware law is
enacted, to permit further indemnification of the directors and officers, then the Executive shall be indemnified to the fullest extent permitted under the General Corporation Law, as so amended, or by such other Delaware law, as so enacted.

  

	 	(o)	Enforcement. The Company expressly confirms and agrees that it has entered into this Amendment in order to induce the Executive to continue to serve as an officer of the
Company, among other things, and acknowledges that the Executive is relying upon this Amendment in continuing in such capacity. 

  

	 	(p)	Consent to Suit. In the case of any dispute under or in connection with this Section 1.4, the Executive may only bring suit against the Company in the Court of Chancery
of the State of Delaware. The Executive hereby consents to the exclusive jurisdiction and venue of the courts of the State of Delaware, and the Executive hereby waives any claim the Executive may have at any time as to forum non conveniens with
respect to such venue. The Company shall have the right to institute any legal action arising out of or relating to this Section 1.4 in any court of competent jurisdiction. Any judgment entered against either of the parties in any proceeding
hereunder may be entered and enforced by any court of competent jurisdiction. 

  

	2.	Reference to and Effect on the Offer Letter; Entire Agreement. The provisions of the Offer Letter shall remain in full force and effect except as amended or superseded by
this Amendment, provided, that, except for the terms of the Offer Letter providing continuation of base salary as severance payments, all other post-termination benefits referenced in the Offer Letter are superceded by this Amendment. This
Amendment, together with the Offer Letter, sets forth the entire agreement (the “Agreement”) of the parties hereto in respect of the subject matter contained herein and supercedes all prior agreements, whether oral or written, by any
officer, employee or representative of any 

  

 - 11 - 

	  	party hereto in respect of the subject matter contained herein; and any prior agreement of the parties hereto in respect of the subject matter contained herein is hereby terminated
and cancelled. For avoidance of doubt, the parties confirm that the foregoing does not apply to or limit the Executive’s rights under Delaware law or the Company’s Certificate of Incorporation or By-Laws. 

  

	3.	Governing Law. Except as set forth in Section 1.4(n), the Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts
without giving effect to principles of conflicts of laws. Except as set forth in Section 1.4(p), any action, suit, or other legal proceeding which is commenced to resolve any matter arising under or relating to any provision of the Agreement
shall be commenced only in a court of the Commonwealth of Massachusetts (or, if appropriate, a federal court located within Massachusetts), and the Company and the Executive each consents to the jurisdiction of such a court.

  

	4.	Section 409A of the Internal Revenue Code. All payments and benefits provided under this Amendment are intended to either comply with or be exempt from Section 409A
of the Code and this Amendment shall be administered and construed accordingly. The Company makes no representations or warranty and shall have no liability to the Executive or any other person if any payments made under this Amendment are
determined to constitute deferred compensation subject to Section 409A but not to satisfy the conditions of that section. 

  

	5.	Successor to Company. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the
business or assets of the Company expressly to assume and agree to perform the Agreement to the same extent that the Company would be required to perform it if no such succession had taken place. As used in the Agreement, “Company” shall
mean the Company as defined above and any successor to its business or assets as aforesaid which assumes and agrees to perform the Agreement, by operation of law or otherwise. 

  

	6.	Counterparts. This Amendment may be executed in two counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same
instrument.

(the “Contracts”); 
 (ix) all lists of past, present and qualified prospective customers of Seller’s

 2 

 Division or the Purchased Assets (including, without limitation, all claims based on any indemnities or
warranties in favor of Seller relating to Seller’s Galvanizing Division or any of the Purchased Assets); 
 (xiii) all
real property owned by Seller, whether or not used in connection with or relating to the Galvanizing Division, together with all interests in such real property, all buildings, improvements and other structures located on such real property, all
uses, easements, appurtenant rights and rights-of-way which benefit such real property and all minerals (including, without limitation, oil, gas, clay, sand and all other surface or subsurface minerals or materials and other substances of any nature
however mined or severed) (the “Owned Real Property”); and 
 (xiv) all other assets and rights of every
kind and nature, tangible or intangible, of Seller, excluding cash on hand. 
 Without limiting the generality of the
foregoing, the Purchased Assets shall, except for the Excluded Assets listed and denoted as such in Section 1.1.1 hereof, include all assets which are held in connection with, or used or held for use in the business or operations of,
Seller’s Galvanizing Division, including those set forth in a detailed list of plant and equipment as of the Balance Sheet Date (as such term is hereinafter defined) prepared from the accounting records of Seller and attached hereto as
Schedule 1.1.1 and denoted as the Purchased Assets therein, and all such assets of Seller as may have been acquired by Seller which would be included on a list prepared in like manner from such accounting records as of the Closing Date,
except any such assets which may have been disposed of since the Balance Sheet Date in the ordinary course of business. 
 1.1.2 Anything herein contained to the contrary notwithstanding, the assets of Seller used solely in connection with or related solely to its Products Division (other than the Owned Real Property) (collectively the “Excluded
Assets”) are specifically excluded from the Purchased Assets and shall be retained by Seller. Without limiting the generality of the foregoing, the Excluded Assets are listed and denoted as such on Schedule 1.1.1 hereof. 

1.1.3 Subject to Section 1.1.4 hereof, at the Closing, Seller shall execute and deliver to Buyer (i) a Bill of Sale,
Assignment and Assumption Agreement, in the form attached hereto as Exhibit A (the “Bill of Sale, Assignment and Assumption Agreement”), under the terms of which Seller shall sell, grant, convey, assign, transfer and deliver
the Purchased Assets to Buyer, and (ii) such other bills of sale, deeds, instruments of assignment and other appropriate documents as may be requested by Buyer in order to carry out the intentions and purposes hereof, which shall include
Limited Deeds in the Form of Exhibit A-1 (the “Deeds”) conveying the Owned Real Property to Buyer. 
 1.1.4 Notwithstanding the foregoing, this Agreement shall not constitute an agreement to assign or transfer any Contract if an assignment or transfer or an 
  

 3 

 attempt to make such an assignment or transfer without the consent of a third party would constitute a
breach or violation thereof or affect adversely the rights of Buyer or Seller thereunder; and any transfer or assignment to Buyer by Seller of any interest under any such Contract that requires the consent or approval of a third party shall be made
subject to such consent or approval being obtained. In the event any such consent or approval is not obtained on or prior to the Closing Date and Buyer waives as of the Closing Date the condition that such consent or approval be obtained, each of
Seller and the Shareholder shall continue to use all reasonable efforts to obtain any such consent or approval after the Closing Date until such time as such consent or approval has been obtained, and each of Seller and the Shareholder will
cooperate with Buyer in any lawful and economically feasible arrangement to provide that Buyer shall receive the interest of Seller in all benefits under any such Contract, including without limitation performance by Seller as agent if economically
feasible; provided, however, that Buyer shall undertake to pay or satisfy the corresponding liabilities for the enjoyment of such benefit to the extent Buyer would have been responsible therefor hereunder if such consent or approval
had been obtained as of the Closing Date 
 1.2 Assumption of Specified Liabilities. Upon the terms and subject
to the conditions set forth herein, subject however to Section 1.1.4 and 1.3 hereof, and as additional consideration for Buyer’s purchase of the Purchased Assets, Buyer shall, at Closing, assume, and covenant and agree to pay, perform and
discharge when due, only the following liabilities and obligations of Seller relating to its Galvanizing Division (the “Assumed Liabilities”): 
 (i) liabilities for accrued vacation and holiday pay for employees of Seller’s Galvanizing Division who are employed by Buyer
immediately after the Closing to the extent such liabilities are reflected on the Interim Financial Statements (as such term is hereinafter defined); and 
 (ii) those liabilities or obligations of Seller relating to its Galvanizing Division accruing or arising after the Closing Date under the terms of a Contract or other obligation which is listed on Schedule 1.2
hereof. 
 Subject to Sections 1.1.4 and 1.3 hereof, at the Closing, Buyer shall execute and deliver to Seller the Bill of
Sale, Assignment and Assumption Agreement assuming the Assumed Liabilities. 
 1.3 Non-Assumption of Certain
Liabilities. Notwithstanding any other provision of this Agreement, Buyer shall not assume, and shall not be deemed to have assumed or be in any way liable for or subject to or have any obligation for or with respect to, any liabilities or
obligations of Seller of any kind, nature or description whatsoever, except as expressly provided in this Section 1.3 or in Section 1.2 hereof (the “Excluded Liabilities”). Anything in Section 1.2 hereof or elsewhere
herein to the contrary notwithstanding and without limiting the generality of the foregoing, Buyer shall not assume, and shall not be deemed to have assumed or be in any way liable for or 
  

 4 

 subject to or have any obligation for or with respect to, any of the following Excluded Liabilities:

 (i) except as specifically provided in Section 1.2(i), any and all claims, liabilities or obligations that arise,
result from, or relate in any way to any or all employment practices, decisions, actions, or proceedings undertaken by Seller prior to or on the Closing Date in connection with persons employed or seeking to be employed, including without limitation

 (ii) any and all liabilities or obligations of Seller in respect of (x) any Taxes (as such term is hereinafter defined) attributable
to periods or events prior to or ending or occurring on the Closing Date, or (y) any Taxes, legal, accounting, brokerage, finder’s fees, or other expenses of whatsoever kind or nature incurred by Seller or any partner, affiliate, director,

respect of products sold or services provided by Seller on or prior to the Closing Date and attributable to acts performed or omitted by Seller on or prior to the Closing Date; or

unknown, existing or occurring at or on any real property or premises (1) owned, leased or occupied by Seller on or prior to the Closing Date, or (2) to which Hazardous Material has been sent or arranged for shipment by Seller on or prior
to the Closing Date (hereafter an “Environmental Condition”), including without limitation (x) any suits, causes of action, proceedings, judgments, administrative and judicial orders arising out of any matter relating to such
Environmental Condition, (y) any liability arising in tort (strict or otherwise) resulting from any such Environmental Condition, and (z) any required cleanup or full or partial remediation of such Environmental Condition in accordance

 2. Closing Consideration;
Adjustment; Allocation of Consideration. 
 2.1 Closing Consideration. The total consideration for the
Purchased Assets shall consist of the following payments: 
 2.1.1 At the Closing, Buyer shall pay to Seller an amount
equal to $12,150,000.00, as adjusted pursuant to this Section 2.1.1, less the Deposit (as defined in Section 2.1.2, (the “Initial Payment”). The Initial Payment shall be made by wire transfer to an account or accounts
designated by Seller by written notice to Buyer given at least two (2) business days prior to the Closing Date. Seller shall deliver to Buyer an estimated balance sheet of the Seller as of the last 
  

 7 

 day of the calendar month preceding the month in which the Closing Date occurs (the “Estimated
Balance Sheet”), such balance sheet to be prepared in accordance with generally accepted accounting principles. If the excess of the total assets reflected on the Estimated Balance Sheet over the value of the Excluded Assets reflected on
the Estimated Balance Sheet (the “Purchased Assets Value”) is greater than $8,802,000.00, the Initial Payment shall be increased by the amount by which the Purchased Assets Value is greater than $8,802,000.00. If the Purchased
Assets Value is less than $8,802,000.00, the Initial Payment shall be decreased by the amount by which the Purchased Assets Value is less than $8,802,000.00. 
 2.1.2 (a) At the Closing, Buyer also shall deposit $715,000.00 (such amount, the “Deposit”) with U.S. Bank,
N.A., as escrow agent (the “Escrow Agent”), which amount shall be held and disposed of pursuant to the terms of this Agreement and an Escrow Agreement in substantially the form attached hereto as Exhibit B (the
“Escrow Agreement”). 
 (b) For United States federal income tax purposes (and any relevant state or local
income, franchise or sales and use taxes purposes), (x) Seller and Buyer shall (x) treat all amounts deposited into the Escrow Fund as the property of Buyer on the date such amounts are deposited into the Escrow Fund, (y) Buyer shall
report and pay any Taxes due and payable on any income earned on or with respect to the funds deposited in the Escrow Fund and (z) upon payment of funds from the Escrow Fund to Seller, Seller shall treat such funds as proceeds from the sale of
Purchased Assets. 
 2.1.3 At the Closing, Buyer and Shareholder shall execute an Environmental Remediation Agreement
in the form attached hereto as Exhibit C (the “Remediation Agreement”), pursuant to which Shareholder shall be responsible for (i) environmental remediation of the Owned Real Property located at Muncie, Indiana (the
“Muncie Property”), and (ii) obtaining a Covenant Not to Sue from the State of Indiana Governor’s office concerning the Muncie Property (the “Covenant Not to Sue”). 
 2.2 Adjustment. 
 2.2.1 Within 90 days after the Closing Date, Seller shall deliver to Buyer financial statements for Seller as of the Closing Date which have been prepared in accordance with, and reflect all audit
adjustments (regardless of amounts or materiality and whether or not waived in prior periods) required by, generally accepted accounting principles applied consistently with Seller’s prior financial statements and audited by Barnes
Dennig & Company, Ltd. (the “Audited Financial Statements”). The balance sheet in the Audited Financial Statements shall separately list the assets and liabilities of the Galvanizing Division and the Products Division. At
the time the audited financial statements are delivered to Seller, Seller shall make available to Buyer copies of the work papers and back-up materials used by Seller’s independent accounting firm in preparing the Audited 
  

 8 

 Financial Statements and such other documents as Buyer may reasonably request in connection with its
review of the Audited Financial Statements. The fees and expenses payable to Barnes Dennig & Company, Ltd. shall be paid 50% by Seller and the Shareholder (jointly and severally) and 50% by Buyer. 
 2.2.2 Within 30 days after Buyer’s receipt of the Audited Financial Statements, Buyer shall review the Audited Financial
Statements and notify Seller in writing whether or not Buyer accepts the Audited Financial Statements. If Buyer accepts the Audited Financial Statements, the Audited Financial Statements shall become final and binding on all parties. 
 2.2.3 If Buyer in good faith objects to any item set forth on the Audited Financial Statements, Buyer shall give notice thereof to
Seller in writing within 30 days after receipt of the Audited Financial Statements, specifying in reasonable detail the nature and extent of such disagreement, and Buyer and Seller shall have a period of 30 days from Seller’s receipt of such
notice in which to resolve such disagreement. Any disputed items which cannot be agreed to by the parties within 30 days from Seller’s receipt of Buyer’s notice of objection to any of the items set forth in the Final Adjustments Report
shall be determined by the Fort Worth, Texas office of the accounting firm of Ernst & Young LLP. The engagement of and the determination by Ernst & Young LLP (or any other accounting firm designated by Ernst & Young LLP as
set forth below) shall be completed within 60 days after such assignment is given to Ernst & Young LLP and shall be final and binding and shall be nonappealable by Seller and Buyer. If for any reason Ernst & Young LLP is unable to
act in such capacity, such determination will be made by any other nationally recognized accounting firm selected by the Fort Worth, Texas office of Ernst & Young LLP. The fees and expenses payable to Ernst & Young LLP (or any
other accounting firm designated by Ernst & Young LLP) in connection with such determination will be borne 50% by Seller and the Shareholder (jointly and severally) and 50% by Buyer, unless (i) the determination of Ernst &

Party”) of such Claim in reasonable detail and stating the amount involved, if known, together with copies of any such written documents.

 (c) If the Claim involves a Third Party Claim, then the Indemnifying Party shall have the right, at its sole cost, expense and ultimate liability regardless of the outcome, and through counsel of its choice

Party, and the Indemnifying Party shall be obligated to pay the costs, expenses and attorney’s fees incurred by the Indemnified Party in connection with such Third Party Claim. In any event, Seller and the Buyer Indemnitees shall fully

in conjunction with one or more other persons or entities, for compensation or not, (i) provide or offer to provide to any Customer (as such term is hereinafter defined) any product or service similar to that offered by Seller’s
Galvanizing Division immediately prior to the Closing Date, or (ii) induce or attempt to induce any Customer to withdraw, curtail or cancel its business with Buyer or any of its subsidiaries or affiliates or in any manner modify or fail to

 29

covenants and agrees that it or she shall not, for a period of five years from and after the Closing Date, working alone or in conjunction with one or more other persons or entities, for compensation or not, permit Seller’s or such
Shareholder’s name to be used by or engage in or carry on, directly or indirectly, either for itself or as a member of a partnership or other entity or as a stockholder, member, investor, agent, associate or consultant of any person,
partnership, corporation, limited liability company or other entity (other than Buyer or a subsidiary or affiliate of Buyer), any business in competition with the galvanizing business purchased hereunder (but only for as long as such business is
carried on by (i) Buyer and/or any of its subsidiaries or affiliates or (ii) any person, corporation, limited liability company, partnership, trust or other organization or entity deriving title from Buyer and/or any of its subsidiaries or
affiliates to the assets and goodwill of such business) in any county in any state of the United States within 500 miles of the Owned Real Property. The parties intend that the covenants contained in this Section 7.1.3 shall be deemed to be a
series of separate covenants, one for each county in each state of the United States within 500 miles of the Owned Real Property and, except for geographic coverage, each such separate covenant shall be identical in terms to the covenant contained
in this Section 7.1.3. The parties shall allocate $300,000 of the Purchase Price to the Restrictive Covenants contained in this Section 7.1.3.

limit is too long, it is expressly understood and agreed between the parties hereto that for purposes of such proceeding such time limitation shall be deemed reduced to the extent necessary to permit enforcement of such covenants. If, in any
judicial proceeding, the court shall refuse to enforce any of the separate covenants contained in Section 7.1.1, 7.1.2 or 7.1.3 hereof because it is more extensive (whether as to geographic area, scope of business or otherwise) than necessary
to protect the business and goodwill of Buyer, it is expressly understood and agreed between the parties hereto that for purposes of such proceeding the geographic area, scope of business or other aspect shall be deemed reduced to the extent
necessary to permit enforcement of such covenants. 
 7.1.5 Injunctive Relief. Each of Seller
and the Shareholder acknowledge that a breach of Section 7.1.1, 7.1.2 or 7.1.3 hereof would cause irreparable damage to Buyer, and in the event of its actual or threatened breach of the provisions of Section 7.1.1, 7.1.2 or 7.1.3 hereof,
Buyer shall be entitled to a temporary restraining order and an injunction restraining Seller and/or the Shareholder from breaching such covenants without the necessity of posting bond or proving irreparable harm, such being conclusively admitted by
Seller and the Shareholder. Nothing shall be construed as prohibiting Buyer from pursuing any other available remedies for such breach or threatened breach, including the recovery of damages from Seller and/or the Shareholder. Each of Seller and the
Shareholder acknowledge that the restrictions set forth in Sections 7.1.1, 7.1.2 and 7.1.3 hereof are reasonable in scope and duration, given the nature of the business of Buyer.

obtaining any such consent, waiver, novation, authorization or approval).

 thereafter. The Allocation determined by Ernst & Young, LLP shall be binding on the Parties, and
the fees of that firm will be paid equally by the Parties. Neither Buyer nor Seller shall take any position with any Taxing authority that is inconsistent with the Allocation. In the event that any Tax authority disputes the Allocation, Seller or
Buyer, as the case may be, shall promptly notify the other party of the nature of such dispute. Seller agrees that Buyer shall control any dispute relating to the Allocation, at Buyer’s sole cost and expense. As used herein, the term
“Total Purchase Price” shall mean the Initial Payment, as adjusted, plus the Deposit. 
 7.9
Proration of Property Taxes. Ad valorem real property and personal property Taxes and assessments on the Purchased Assets shall be prorated between Buyer and Seller as of the Closing Date, based on estimates of the amount of taxes that
will be due and payable on the Purchased Assets during the calendar year in which the Closing Date occurs. Subsequent to Closing, after the amount of taxes and assessments on the Purchase Assets for such year is known, Seller and Purchaser shall
readjust the amount of taxes to be paid by each party with the result items relating to time periods ending on or prior to the Closing Date shall be allocated to Seller and items relating to time periods beginning after the Closing Date shall be
allocated to Buyer. 
 7.10 Offer of Employment. Buyer may, but shall not be required to, offer employment to
individuals who are employees of Seller on the Closing Date, in accordance with Buyer’s normal hiring practices. Buyer, or its affiliates, shall offer employment to a sufficient number of Seller’s Galvanizing Division employees on such
terms and conditions so that Seller is not required to provide notice of a “plant closing” or “mass layoff” to any person or entity under the Worker Adjustment and Retraining Notification Act of 1988, 29 U.S.C. § 2101 et
seq. or any other similar federal, state or local law or regulation (the “WARN Act”) as a result of the termination of employment or its employees by Seller as of the Closing. Set forth on Schedule 7.10 hereof is a list of
all employees of Seller’s Galvanizing Division as of the date hereof and their annual rate of compensation. Seller shall cooperate with all requests made by Buyer for the purpose of facilitating Buyer’s hiring of such employees. As used
herein, “Transferred Employees” shall mean all such employees to whom employment is offered by Buyer as provided above and who accept employment with Buyer, including without limitation those on medical, disability or other leave of
absence. Buyer shall comply with all provisions of the WARN Act with respect to all of Seller’s employees employed in the Galvanizing Division. Buyer shall permit all Transferred Employees to participate in Buyer’s 401(k) plan pursuant to
the terms thereof and, in connection therewith, shall credit each Transferred Employee with the number of days such Transferred Employee was employed by Seller for purposes of any length of service requirements under such 401(k) plan. Nothing herein
expressed or implied shall confer upon any Transferred Employee or other employee or former employee of Seller or legal representatives thereof, any rights or remedies, including without limitation any right to employment or continued employment for
any specified period, of any nature or kind whatsoever, or, except as otherwise provided in this Section 7.10, any right to specific terms or conditions of employment (including rate of pay, fringe benefits or position) under or by reason of
this Agreement. The employment of any Transferred Employee or all Transferred Employees may be terminated by Buyer for any reason or for no reason at 
  

 33 

 any time after the Closing Date. With respect to employees who either are not extended an offer of
employment with Buyer or who choose not to accept an offer of employment with Buyer, Seller and the Shareholder covenant and agree to cooperate with and to assist Buyer at Buyer’s sole cost and expense in obtaining the agreement of those
employees to continue to be available to Buyer during a transition period of six months beginning on the Closing Date. 
 7.11 Guaranty of Receivables. At the Closing, Seller and the Shareholder shall execute and deliver to Buyer a Guaranty in the form attached as Exhibit E hereto (the “Receivables Guaranty”), under the
terms of which Seller and the Shareholder shall, jointly and severally, unconditionally guarantee that all indebtedness represented by the accounts and notes receivable of Seller as of the Closing Date that are included in the Purchased Assets (net
of any allowance for doubtful accounts on the Interim Financial Statements) will be paid by the respective debtors to Buyer. In the event such net indebtedness is not paid within 180 days after the Closing Date, Seller and the Shareholder shall,
jointly and severally, within ten days following receipt from Buyer of notice to such effect, make payment to Buyer of an amount in cash equal to the difference between such net indebtedness and the amount collected in respect of such accounts and
notes receivable, whereupon Buyer shall promptly assign or cause to be assigned to Seller or the Shareholder all rights, claims, actions or causes of action which Buyer may have relating to such unpaid receivables. All out-of-pocket costs and
expenses incurred by Buyer during the six-month period immediately after the Closing Date with respect to the collection of such accounts and notes receivable (including, without limitation, attorneys’ fees and court costs) shall be the sole
responsibility of Seller and the Shareholder, and Seller and the Shareholder shall reimburse Buyer therefor as part of the Receivables Guaranty. Following the Closing Date, Buyer shall send statements to the account debtors or note makers, write
letters and make telephone calls seeking payment. Buyer shall not be obligated to commence a suit to enforce payment of any accounts or notes receivable or undertake any extraordinary collection efforts. 
 7.12 Real Estate Covenants and Conditions. 
 7.12.1 With respect to the Owned Real Property, Buyer, at its sole cost and expense, shall have obtained (i) a commitment for title insurance (a “Title Commitment”), from a title company
of Buyer’s choice (the “Title Company”), setting forth the status of the title of the Owned Real Property and showing all title encumbrances and other matters of record (“Real Property Encumbrances”) and all
improvements thereon; and (ii) a true, complete and legible copy of all documents referred to in such Title Commitment. 
 7.12.2 Buyer, at Buyer’s sole cost and expense, shall have obtained a survey for the Owned Real Property (the “Survey”) consisting of a plat and field notes. The Survey shall have been prepared pursuant to a

(as defined in Section 7.12.4). 
 7.12.3 At least three days prior to Closing, Seller shall have delivered to
Buyer: (i) copies of the tax statements covering the Owned Real Property for the year prior to the current year and, if available, for the current year, (ii) copies of any leases affecting the Owned Real Property, if any, (iii) copies
of all reports, surveys, and studies, including, without limitation, any environmental studies, prepared by or on behalf of any Seller with respect to the Owned Real Property, and (iv) copies of any documents, notices, or information in
Seller’s possession relating to: any easements or claims of easement, rights, rights-of-way, licenses or other unrecorded interests of third parties (other than pursuant to the leases) in and to the Owned Real Property, the condition of the
Owned Real Property, including any Environmental Condition or condition constituting a violation of any ordinance, regulation, law, or statute of any governmental agency, including, without limitation, any Environmental Law or zoning ordinance; and
any threatened or pending administrative or condemnation proceedings or litigation with respect to the Owned Real Property. 
 7.12.4 At the Closing, Buyer shall have obtained, at Buyer’s sole expense, an ALTA Standard Form Owner Policy of Title Insurance (the “Owner Title Policy”) for the Owned Real Property, in such amount as
reasonably determined by Buyer, and issued through the Title Company pursuant to the applicable Title Commitment, insuring that, after the completion of the Closing, Buyer is the owner of good and marketable fee simple title to the Owned Real
Property subject only to the Real Property Encumbrances and the standard printed exceptions included in an ALTA Standard Form Owner Policy of Title Insurance. Seller shall do such further acts and execute such other documents as may reasonably be
required by Title Company to issue to Buyer the Owner Title Policy. At the Closing, Seller shall deliver or cause to be delivered to Buyer the Deeds with respect to the Owned Real Property, conveying good, marketable and indefeasible fee simple
title to the Owned Real Property, subject to the Permitted Title Encumbrances. Other than the Real Property Lease attached hereto as Exhibit F, pursuant to which Buyer will lease to Seller a portion of the Owned Real Property currently used
by the Company in connection with its Products Division on the terms and conditions set forth therein, upon completion of the Closing, Seller shall deliver to Buyer actual possession of the Owned Real Property free and clear of all tenancies of
every kind and parties in possession, with all parts of the Owned Real Property in substantially the same condition as on the date of this Agreement. 
  

 35 

 7.12.5 Prior to Closing, upon giving 24 hour notice to Seller, Buyer and its
agents, contractors, or representatives, at Buyer’s sole cost, may go on to the Owned Real Property to make inspections, surveys, test borings, environmental inspections, and other tests and surveys.

Real Property located in Cincinnati, Ohio (the “Cincinnati Property”), hereby assigns any and all right, title and interest in and to any monies received from the City of Cincinnati, Ohio, the United States Army Corps of Engineers, or
other federal, state or local governmental entity or agency, pursuant to the conveyance of any easement rights with respect to the Cincinnati Property in connection with, relating to or arising out of the Duck Creek Local Flood Protection project,
as described under the proposed Contract for City Easements and/or Improvements attached hereto as Exhibit M, or under any similar project or proposal (“Easement Payment”). Upon the receipt of any Easement Payment, the recipient of

 9.2 Binding Effect; Benefits. This Agreement shall be binding upon and shall inure to the benefit of the
parties and their respective successors and permitted assigns. Notwithstanding anything contained herein to the contrary, nothing in this Agreement, expressed or implied, is intended to confer on any person (other than the parties hereto, the Buyer
Indemnitees (but only with respect to Section 6 hereof), or their respective successors and permitted assigns) any rights, remedies, obligations or liabilities under or by reason of this Agreement. 
  

 40 

 9.3 Entire Agreement. This Agreement, together with the Exhibits, Schedules
and other agreements and documents contemplated hereby, constitutes the final written expression of all of the agreements between the parties, and is a complete and exclusive statement of those terms. Except as specifically included or referred to
herein, this Agreement and the Exhibits, Schedules and other agreements and documents contemplated hereby supersede all prior understandings, negotiations and agreements concerning the matters specified herein. Any representations, promises,
warranties or statements made by any party that differ in any way from the terms of this written Agreement, and the Exhibits, Schedules and other agreements and documents contemplated hereby, shall be given no force or effect (except as specifically
included or referred to herein). The parties specifically represent, each to the others, that there are no additional or supplemental agreements between them related in any way to the matters herein contained unless specifically included or referred
to herein. No addition to or modification or amendment of any provision hereof shall be binding upon any party hereto unless made in writing and signed by all parties hereto. 
 9.4 Governing Law. THIS AGREEMENT, AND ALL QUESTIONS RELATING TO ITS VALIDITY, INTERPRETATION, PERFORMANCE AND
ENFORCEMENT (INCLUDING, WITHOUT LIMITATION, PROVISIONS CONCERNING LIMITATIONS OF ACTION), SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS (EXCLUSIVE OF THE CONFLICT OF LAW PROVISIONS THEREOF) APPLICABLE TO
AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE. 
 9.5 Counterparts. This Agreement may be
executed in any number of counterparts, each of which shall be deemed an original but all of which shall constitute one and the same instrument; but in making proof of this Agreement, it shall not be necessary to produce or account for more than one
such counterpart. It is not necessary that each party execute the same counterpart, so long as identical counterparts are executed by all parties. Executed signature pages to any counterpart instrument may be detached and affixed to a single
counterpart, which single counterpart with multiple signature pages affixed thereto constitutes an original counterpart instrument. All such counterpart signature pages shall be read as though one and they shall have the same force and effect as if
all of the parties had executed a single signature page. 
 9.6 Headings. Headings of the Sections of this
Agreement are for the convenience of reference only, and shall be given no substantive or interpretive effect whatsoever. 
 9.7 Waivers. Any party may, by written notice to the other parties, (i) extend the time for the performance of any of the obligations or other actions of the other parties hereunder; (ii) waive any inaccuracies in
the representations or warranties of the other parties contained herein or in any other agreement or document delivered pursuant 
  

 41 

 hereto; (iii) waive compliance with any of the conditions or covenants of the other parties
contained herein; or (iv) waive performance of any of the obligations of the other parties hereunder. Except as provided in the preceding sentence, no action taken pursuant hereto, including without limitation any investigation by or on behalf
of any party, shall be deemed to constitute a waiver by the party taking such action of compliance with any representations, warranties, covenants or agreements contained herein. No failure or delay on the part of any party in exercising any right,
privilege, power or remedy under this Agreement, and no course of dealing among the parties, shall operate as a waiver of such right, privilege, power or remedy; nor shall any single or partial waiver or exercise of any right, privilege, power or
remedy under this Agreement preclude any other or further exercise of such right, privilege, power or remedy, or the exercise of any other right, privilege, power or remedy. No notice or demand on any party in any case shall entitle such party to
any other or future notice or demand in any similar or other circumstances or constitute a waiver of the right of the party giving such notice or making such demand to take any other or future action in any circumstances without notice or demand.
Notwithstanding the foregoing, by executing this Agreement, the Parties acknowledge that the conditions to Closing set forth in Article 8 have either been complied with or waived. 
 9.8 Merger of Documents. This Agreement and all agreements and documents contemplated hereby constitute one agreement and
are interdependent upon each other in all respects. 
 9.9 Incorporation of Exhibits and Schedules. All Exhibits
and Schedules attached hereto are by this reference incorporated herein and made a part hereof for all purposes as if fully set forth herein. 
 9.10 Severability. If for any reason whatsoever, any one or more of the provisions hereof shall be held or deemed to be illegal, inoperative, unenforceable or invalid as applied to any particular case or
in all cases, such circumstances shall not have the effect of rendering such provision illegal, inoperative, unenforceable or invalid in any other case or of rendering any of the other provisions hereof illegal, inoperative, unenforceable or
invalid. Furthermore, in lieu of each illegal, invalid, unenforceable or inoperative provision, there shall be added automatically, as part of this Agreement, a provision similar in terms of such illegal, invalid, unenforceable or inoperative
provision as may be possible and as shall be legal, valid, enforceable and operative. 
 9.11 Assignability.
Neither this Agreement nor any of the parties’ rights hereunder may be assigned or otherwise transferred by any party without the prior written consent of the other parties; provided, however, that Buyer’s or its
successors’ or assigns’ rights hereunder may be assigned or otherwise transferred, in whole or in part, without any other party’s consent (i) to any successor by merger or consolidation, (ii) to any bank or other financial
institution, or to any individual, partnership, corporation or other entity, providing any financing to Buyer, its successors or assigns, or (iii) to any individual, partnership, corporation or other entity deriving title from Buyer, or its
successors or assigns, to all or substantially all of the Purchased Assets as constituted on the date of any such transfer. No assignment or other transfer permitted by this Section 9.11 shall 
  

 42 

 operate as a release of the assignor’s obligations or liabilities hereunder, and the assignor shall
remain liable hereunder notwithstanding such assignment or other transfer. In the event of any assignment or other transfer permitted by this Section 9.11, an instrument of assignment shall be executed by the assignee and shall expressly state
that the assignee assumes all of the applicable obligations and liabilities of the assignor contained herein. 
 9.12
Drafting. The parties acknowledge and confirm that each of their respective attorneys has participated jointly in the review and revision of this Agreement and that it has not been written solely by counsel for one party. The parties
therefore stipulate and agree that the rule of construction to the effect that any ambiguities are to be or may be resolved against the drafting party shall not be employed in the interpretation of this Agreement to favor any party against another.

 9.13 References. The use of the words “hereof,” “herein,” “hereunder,”
“herewith,” “hereto,” “hereby,” and words of similar import shall refer to this entire Agreement, and not to any particular article, section, subsection, clause, or paragraph of this Agreement, unless the context
clearly indicates otherwise. 
 9.14 Calendar Days, Weeks and Months. Unless otherwise, specified herein, any
reference to “day,” “week,” or “month” herein shall mean a calendar day, week or month. 
 9.15 Gender; Plural and Singular. Where the context clearly indicates otherwise, the singular shall include the plural and vice versa. Whenever the masculine, feminine or neuter gender is used inappropriately in this
Agreement, this Agreement shall be read as if the appropriate gender had been used. 
 9.16 Cumulative Rights.
All rights and remedies specified herein are cumulative and are in addition to, not in limitation of, any rights or remedies the parties may have at law, in equity, or otherwise, and all such rights and remedies may be exercised singularly or
concurrently. 
 9.17 No Implied Covenants. Each party, against the other, waives and relinquishes any right to
assert, either as a claim or as a defense, that the other party is bound to perform or liable for the nonperformance of any implied covenant or implied duty or implied obligation. 
 9.18 Attorneys’ Fees. The prevailing party in any dispute between the parties arising out of the interpretation,
application or enforcement of any provision hereof shall be entitled to recover all of its reasonable attorney’s fees and costs whether suit be filed or not, including without limitation costs and attorneys’ fees related to or arising out
of any trial or appellate proceedings. 
 9.19 Indirect Action. Where any provision hereof refers to action to
be taken by any person or party, or which such person or party is prohibited from taking, such provision shall be applicable whether the action in question is taken directly or indirectly by such person or party.
