 40 








 
of any Hazardous Substance or contaminants in, on, at upon or under any surface soil, subsurface soil, surface water, groundwater, building material or any
other media of any form or type at, in, on, under or from the Real Estate (collectively “Media”) except to the extent that Purchaser, in its sole discretion, concludes that an investigation and/or sampling of any Media is
(A) done in connection with a future sale of the Real Estate by Purchaser to a bona fide third party purchaser; (B) done in connection with a bona fide third party financing transaction in which Purchaser or any of its affiliates is the
borrowing entity; (C) warranted by any future construction or development on the Real Estate by Purchaser (and then only to the extent related to the area of construction or development); (D) required by Law or (E) done in connection
with a response to a bona fide Third Party Claim asserting liability for the Release of Hazardous Substances at the Real Estate (items (A) through (E) referred to as “Permissible Activities”).

Permissible Activities shall, after giving effect to subsection (d)(i) hereof, be borne in the proportion of twenty-five percent (25%) by Purchaser and seventy-five percent (75%) by Sellers. 
 (iii) With respect to Sellers’ indemnification obligations for Environmental Losses under Section 9.3(a) or (b) above as a
result of a breach of a representation or warranty set forth in Section 3.16 above or otherwise, Purchaser shall: 
 (A)
provide Sellers or their Representatives access to the applicable Real Estate so that Sellers may conduct their own investigation, testing or corrective action with respect to the matter; 
 (B) immediately provide Sellers with the results, including analytical data, of any investigation or testing conducted by Purchaser or,
if available to Purchaser, any third party; 
 (C) give Sellers the right to participate in any discussions or negotiations
with any Governmental Authority concerning such matter; 
 (D) if Remediation Action is required in any such matter, give
Sellers the right to develop and implement a plan of corrective action, such plan to be paid for by Sellers and be subject to Purchaser’s approval, and, if requested by Sellers, cooperate with Sellers in the development and implementation of
such plan on a cost effective basis; any such plan of action may, to the extent permitted under Environmental Laws, be based on the industrial use of the property and may rely on and utilize institutional controls (such as web-based GIS
registrations, deed notices or restrictions) and shall contain reasonable steps so as to minimize disruption of or adverse effect on the ongoing operations of the business of the Schaefer Companies; and 
 (E) cooperate fully and in good faith with Sellers in performing such tasks as Sellers and their technical professionals and
Representatives may reasonably request as being necessary to complete any Remediation Action being undertaken by Sellers pursuant to this Agreement; and Purchaser shall promptly execute any and all documentation necessary or requested to facilitate
“case closure” or a similar acknowledgement 

  

 41 








 
by any Governmental Authority having jurisdiction over the matter and, furthermore, without limiting the scope of the foregoing, Purchaser shall cause its
employees to cooperate fully with Sellers and to afford Sellers, their agents, employees and technical professionals access to relevant records relating to the matters which may be Sellers’ responsibility under this Agreement; 
 (iv) Upon issuance of a “No Further Action” (“NFA”) letter or similar acknowledgement from a Governmental
Authority having jurisdiction over a particular Remediation Action, all obligations of Sellers under this Agreement with respect to the applicable Environmental Losses for that particular Remediation Action, if any, shall be terminated and concluded
to the extent such NFA letter releases Purchaser from all future liability with regard to such matter. 
 (f) If Purchaser is
indemnified under this Section 9.3 with respect to any Losses incurred or sustained by it as a result of the breach of the representation and warranty made by Sellers in the penultimate sentence of Section 3.24 (relative to Accounts
Receivable outstanding for greater than 120 days), Purchaser shall assign its right to any such Account Receivable to Sellers. 
 (g) Indemnification amounts finally determined to be payable by Sellers shall be satisfied first from the Escrow Amount to the extent available. The Escrow Agreement shall continue for three years except as extended with respect to pending

(ii) one-half of amount then held in the escrow fund shall be released to Sellers at the two year anniversary of the Closing Date and (iii) the remainder of the funds held in the escrow fund shall be released at the third anniversary of
the Closing Date except as may be extended as set forth in the Escrow Agreement. Procedures for obtaining disbursements of the amounts held in the escrow fund shall be as set forth in the Escrow Agreement. 
 (h) The indemnification obligations of Sellers under subsection 9.3(a)(iii) above shall be without regard to the provisions of subsection
(d) hereof. 
 9.4 Procedures for Indemnification. 
 (a) Subject to Section 9.5, if a Party seeking indemnification pursuant to this Section 9 (an “Indemnified
Party”) shall claim to have suffered a Loss for which indemnification is available under Sections 9.2 or 9.3, as the case may be (for purposes of this Section 9.4, regardless of whether such Indemnified Party is entitled to receive a
payment in respect of such claim), the Indemnified Party shall notify the Party from whom indemnification with respect to such claim is sought (the “Indemnifying Party”) in writing of such claim within the applicable Cut-Off Date,
which written notice shall describe the nature of such claim, the facts and circumstances that give rise to such claim to the extent then known by the Indemnified Party and the amount of such claim if reasonably ascertainable at the time such claim
is made (or if not then reasonably ascertainable, the maximum amount of such claim reasonably estimated by the Indemnified Party). 
  

 42 








 (b) In the event of a claim by an Indemnified Party involves Losses that do not result
from a Third-Party Claim, then the Parties shall follow the procedures set forth in Section 10 with respect to the resolution of such matter. 
 9.5 Procedures for Third-Party Claims. 
 (a) Any Indemnified Party seeking
indemnification pursuant to this Section 9 in respect of any Proceeding instituted by any third Person (in each case, a “Third-Party Claim”) shall give the Indemnifying Party from whom indemnification with respect to such claim
is sought (i) prompt written notice (but in no event more than ten (10) days after the Indemnified Party acquires knowledge thereof) of such Third-Party Claim and (ii) copies of all documents and information relating to any such
Third-Party Claim within ten (10) days of their being obtained by the Indemnified Party; provided, that the failure by the Indemnified Party to so notify or provide copies to the Indemnifying Party shall not relieve the Indemnifying
Party from any liability to the Indemnified Party for any liability hereunder except to the extent that such failure shall have actually prejudiced the defense of such Third-Party Claim. 
 (b) The Indemnifying Party shall have the right, at its option and expense, to defend against, negotiate, settle or otherwise deal with
any Third-Party Claim with respect to which it is the Indemnifying Party and to be represented by counsel reasonably acceptable to the Indemnified Party (unless (i) the Indemnifying Party is also party to such Proceeding and the Indemnified
Party determines in good faith that joint representation would be inappropriate or (ii) the Indemnifying Party fails to provide reasonable assurance to the Indemnified Party of its financial capacity to defend such Proceeding and provide
indemnification with respect to such Proceeding). The Indemnifying Party shall notify the Indemnified Party of its election to assume the defense of such Proceeding and thereafter neither the Indemnifying Party nor the Indemnified Party will admit
any liability with respect thereto or settle, compromise, pay or discharge the same without the written consent of the other party. The Indemnified Party may participate in any Third-Party Claim with counsel of its choice and at its expense. If
notice is given to an Indemnifying Party of the commencement of any Proceeding and the Indemnifying Party does not, within twenty days after such notice is given, give notice to the Indemnified Party of its election to assume the defense of such
Proceeding, the Indemnified party (upon further notice to the Indemnifying Party) will have the right to undertake the defense, compromise or settlement of such Proceeding and the Indemnifying Party will be bound by any determination made in such
Proceeding or any compromise or settlement effected by the Indemnified Party. Notwithstanding the foregoing, if an Indemnified Party determines in good faith that there is a reasonable probability that a Proceeding may adversely affect it or its
affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the Indemnified Party may, by written notice to the Indemnifying Party, assume the exclusive right to defend, compromise or
settle such Proceeding, but the Indemnifying Party will not be bound by any determination of a Proceeding so defended or any compromise or settlement effected without its written consent. 
 (c) If a firm good faith written offer is made to settle any such Third-Party Claim and the Indemnifying Party proposes to accept such
settlement and the Indemnified Party refuses to consent to such settlement, then: (i) the Indemnifying Party shall be excused from, and the Indemnified Party shall be solely responsible for, all further defense of such 

  

 43 








 
Third-Party Claim; (ii) the maximum liability of the Indemnifying Party relating to such Third-Party Claim shall be the amount of the proposed
settlement if the amount thereafter recovered from the Indemnified Party on such Third-Party Claim is greater; and (iii) the Indemnified Party shall pay all attorneys’ fees and legal costs and expenses incurred after rejection of such
settlement by the Indemnified Party, but if the amount thereafter recovered by such third party from the Indemnified Party is less than the amount of the proposed settlement, the Indemnified Party shall be reimbursed by the Indemnifying Party for
such attorneys’ fees and legal costs and expenses up to a maximum amount equal to the difference between the amount recovered by such third party and the amount of the proposed settlement. 
 (d) Purchaser and Sellers shall make available to each other, their counsel and accountants all information and documents reasonably
available to them which relate to any claim subject to indemnity hereunder and to render to each other such assistance as may reasonably be required in order to ensure the proper and adequate defense of any such claim. 
 (e) If required for joinder purposes, the Sellers and Purchaser hereby consent to the non-exclusive jurisdiction in which a Proceeding is
brought against any Indemnified Party for purposes of any claim that an Indemnified Party may have under this Agreement with respect to such Proceeding or the matters alleged therein and agree that process may be served on the Sellers and Purchaser
with respect to such claim anywhere in the world. 
 9.6 Exclusive Remedy. In the absence of fraud, bad faith or
willful breach, the indemnification obligations of Purchaser and Sellers under this Section 9 shall constitute the sole and exclusive remedies of Sellers and Purchaser, respectively, and their respective Representatives, shareholders and
controlling Persons, for the breach of any covenant, agreement, representation or warranty included in this Agreement by the Sellers or Purchaser, as the case may be, and Sellers and Purchaser shall not be entitled to rescission of this Agreement or
to any further indemnification rights or claims of any nature whatsoever in respect thereof, all of which Purchaser and Sellers waive. 
 10. DISPUTE RESOLUTION. 
 10.1 Dispute. As used in this Agreement, “Dispute”
shall mean any dispute or disagreement between Purchaser and Sellers concerning the interpretation of this Agreement, the validity of this Agreement, any breach or alleged breach by any Party under this Agreement or any other matter relating in any
way to this Agreement; provided, that “Dispute” shall not include any dispute (i) relating to the Preliminary Closing Balance Sheet, which shall be resolved in accordance with Section 2.4(f), (ii) arising under
Article 6 hereof, which shall be resolved in accordance with Section 6.5 or (iii) any dispute arising under Section 12 of this Agreement. 
 10.2 Process. If a Dispute arises, the Parties to the Dispute shall follow the procedures specified in Sections 10.3, 10.4 and 10.5. 
 10.3 Negotiations. The Parties shall promptly attempt to resolve any Dispute by negotiations between Purchaser and Sellers’
Agent. Purchaser or Sellers’ Agent, as the case may be, shall give the other Party written notice (the “Dispute Notice”) of any Dispute not 

  

 44 








 
resolved in the normal course of business. Purchaser and Sellers’ Agent (or their Representatives) shall meet at a mutually acceptable time and place
within thirty (30) days after receipt of the Dispute Notice by the party to whom such Notice was delivered, and thereafter as often as they reasonably deem necessary, to exchange relevant information and to attempt to resolve the Dispute. If
Purchaser or Sellers’ Agent intends to be accompanied at any such meeting by legal counsel, the other Party shall be given at least three (3) Business Days’ prior written notice of such intention and may also be accompanied by legal
counsel. If the Dispute has not been resolved by the Parties (A) within ninety (90) days of receipt of a Dispute Notice, or (B) if the Parties fail to meet within thirty (30) days of receipt of such Dispute Notice, either
Purchaser or Sellers’ Agent may initiate binding arbitration as provided in Section 10.4. 
 10.4
Arbitration. If the Dispute is not resolved by negotiations pursuant to Section 10.3, all Disputes shall be determined by binding arbitration in Chicago, Illinois in accordance with the commercial rules of the AAA then in effect unless
the parties mutually agree in writing to waive this provision. This agreement to arbitrate shall be specifically enforceable under the laws of the State of Illinois. The Party initiating arbitration shall file written notice of the demand for
arbitration with the other Party to the Dispute and with the AAA in Chicago, Illinois. Such demand for arbitration shall be made within sixty (60) days after the expiration of the applicable time period set forth in the last sentence of
Section 10.3, and in no event shall such demand be made after the date when an institution of legal or equitable proceedings based upon such Dispute would be barred by this Agreement or the applicable statute of limitations. The arbitration
shall be before a single arbitrator chosen in accordance with the rules of the AAA, who shall interpret this Agreement in accordance with the internal laws of the Commonwealth of Pennsylvania without reference to any rule or provision thereof which
would cause the application of the law of any other state. The award rendered by the arbitrator shall be final and binding and may not be appealed, and any judgment may be entered upon it in accordance with the applicable law in any court having
jurisdiction thereof. In no event shall any Party be awarded punitive damages. 
 10.5 General. 
 (a) Provisional Remedies. At any time during the procedures specified in Sections 10.3 and 10.4, a Party may seek a preliminary
injunction or other provisional judicial relief in the courts of Cook County, Illinois or the U.S. District Court for the Northern District of Illinois if in the judgment of such party such action is necessary to avoid irreparable harm. Each party
hereto consents to the exclusive jurisdiction of such courts with respect to this Section 10.5 and waive any objection to venue laid therein. Process in any Proceeding referred to in this Section 10.5 may be served on any party anywhere in
the world. 
 (b) Performance to Continue. Each Party shall use its commercially reasonable efforts to perform its
obligations under this Agreement pending final resolution of any Dispute. 
 (c) Extension of Deadlines. All deadlines
specified in this Section 10 may be extended by mutual written agreement between Purchaser and Sellers’ Agent. 
  

 45 








 (d) Enforcement. The Parties regard the obligations in this Section 10 to
constitute an essential provision of this Agreement and one that is legally binding on them. In case of a violation of the obligations in this Section 10 by either Purchaser or any of Sellers or the Sellers’ Agent, the other Party may
bring an action to seek enforcement of such obligations in any court of law having jurisdiction thereof. 
 (e) Costs.
The Parties to the dispute shall pay their own costs, fees, and expenses incurred in connection with the application of the provisions of this Section 10, and fifty percent (50%) of the fees and expenses of the AAA and the arbitrator in
connection with the application of the provisions of Section 10.4. 
 10.6. Waiver of Jury Trial. In any court
action under this Section 10 as contemplated above (whether to enforce an arbitration award as contemplated in Section 10.4, to seek provisional remedies as contemplated in Section 10.5(a), to enforce the arbitration provisions
contained in this Section 10 as contemplated in Section 10.5 (d), or otherwise), the Purchaser and Sellers hereby voluntarily, knowingly, irrevocably and unconditionally waive any right to have a jury participate in resolving the dispute
which is the subject of such court action. 
 11. [RESERVED] 
 12. NONCOMPETITION. 
 12.1 Acknowledgments by Shareholders. Each Seller acknowledges, to the extent applicable to such Seller, that: 
 (a) such Seller has occupied a position of trust and confidence with the Company prior to the Closing Date and has become familiar with the Information; 
 (b) Purchaser has required that each Seller make the covenants set forth in Sections 12.2 and 12.3 as a condition to the Purchaser’s
purchase of the Shares; 
 (c) the provisions of Sections 12.2 and 12.3 are reasonable and necessary to protect and preserve
the Company’s business; and 
 (d) the Company would be irreparably damaged if any Seller were to breach the covenants
set forth in Sections 12.2 and/or 12.3. 
 12.2 Confidential Information. Each Seller acknowledges and agrees that all
Information known or obtained by such Seller, whether before or after the Closing Date, is the property of the Company. Therefore, each Seller agrees that such Seller will not, at any time, disclose to any unauthorized Persons or use for its or his
own account or for the benefit of any Person any Information, whether such Seller has such Information in its or his memory or embodied in writing or other physical form, without Purchaser’s prior written consent. Each Seller agrees to deliver
to Purchaser within 30 days after execution of this Agreement, and at any other time Purchaser may reasonably request, all physical embodiments of any Information that such Seller may then possess or have under its or his control. 
  

 46 








 12.3 Noncompetition. As a material inducement for Purchaser to enter into this
Agreement and as additional consideration for the consideration to be paid hereunder, each Seller agrees that: 
 (a) For a
period of twenty-four (24) months after the Closing: 
 (i) such Seller will not, directly or indirectly, engage or
invest in, own, manage, operate, finance, control, or participate in the ownership, management, operation, financing, or control of, be employed by, associated with, or in any manner connected with, lend its or his name or any similar name to, lend
its or his credit to, or render services or advice to any business that competes with any business conducted by any of the Schaefer Companies in the United States; provided, that such Seller may purchase or otherwise acquire up to (but not
more than) one percent of any class of securities of any enterprise (but without otherwise participating in the activities of such enterprise) if such securities are listed on any national or regional securities exchange or have been registered
under Section 12(g) of the Securities Exchange Act of 1934. Each Seller agrees that this covenant is reasonable with respect to its duration, geographical area, and scope; 
 (ii) such Seller will not, directly or indirectly, either for itself or himself or any other Person, (A) induce or attempt to induce
any employee of any of the Schaefer Companies to leave the employ of such Company, (B) in any way interfere with the relationship between any such Company and any employee of such Company, (C) employ, or otherwise engage as an employee,
