to the Seller Savings Plans by and/or on behalf of the Continuing Employees shall cease. Seller shall timely make all contributions under the
Seller Savings Plans with respect to service up to the Closing Date. As soon as practicable following the Closing Date, the trust(s) maintained under the Seller Savings Plans shall, with respect to each participating Active Employee, transfer to the
trust maintained under the plan maintained by Purchaser that is qualified under Sections 401(a) and 401(k) of the Code (and such trust shall accept receipt of) assets equal to the transferred balances of the Continuing Employees, together with all
liabilities of the Seller Savings Plans with respect to such transferred balances. The transferred assets shall consist of cash together with the interest of the Seller Savings Plans in any outstanding plan loan(s) to such Continuing Employees which
loan(s) constitute a part of each such Active Employees plan account(s). Seller, its Controlled Group Member, as applicable, and Purchaser shall make reasonable arrangements for continuation of payments by the Continuing Employees with respect
to any of their outstanding plan loans during the period from the Closing Date to the date of such trustee-to-trustee transfer.



(d) As of the Closing Date, all benefits accrued by any employee of the Company or any of its Subsidiaries who, immediately prior to the
Closing, participates in the BMAC Retirement Plan I or the BMAC Retirement Plan II shall be frozen (based on compensation history and service performed as of the Closing Date) and, thereafter, shall be paid in accordance with the terms of such
plans. Purchaser shall assume no liability in respect of any payment of benefits under either such plan.



(e) No provision of this Section 8.4 shall create any third-party beneficiary rights in any person or organization, including without
limitation employees or former employees (including any beneficiary or dependent thereof) of Seller or any of their Affiliates, unions or other representatives of such employees or former employees, or trustees, administrators, participants or
beneficiaries of any employee benefit plan, and no provision of this Section 8.4 shall create such third-party beneficiary rights in any such person or organization in respect of any benefits that may be provided, directly or indirectly, under any
employee benefit plan or arrangement, including currently existing Employee Benefit Plans of Seller.



(f) Seller, Sellers Affiliates, Purchaser and Purchasers Affiliates shall cooperate as may reasonably be requested with
respect to each of the filings, calculations and other actions necessary to effect the transactions contemplated by this Section 8.4 and in obtaining any governmental approvals required hereunder.



(g) Purchaser shall be responsible for and assume and honor
the obligations referred to in Schedule 8.4(g).



(h) Neither Purchaser nor any of Purchasers Affiliates shall take any action within the five-year period following the Closing Date to cause Seller or any of Sellers Affiliates to incur any liability under any
Multiemployer Plan as a result of a complete withdrawal or partial withdrawal from a Multiemployer Plan within such five-year period following the Closing Date (other than such liability as Seller or such Sellers Affiliate would otherwise have
incurred in connection with such complete withdrawal or partial withdrawal based solely on contribution history under such Multiemployer Plan attributable to the business and operations of Seller or such Sellers Affiliate). Neither Seller nor
any of Sellers Affiliates

shall take any action within the five-year period following the Closing Date to cause Purchaser or any of Purchasers Affiliates to
incur any liability under any Multiemployer Plan as a result of a complete withdrawal or partial withdrawal from a Multiemployer Plan within such five-year period following the Closing Date (other than such liability as Purchaser or such
Purchasers Affiliate would otherwise have incurred in connection with such complete withdrawal or partial withdrawal based solely on contribution history under such Multiemployer Plan attributable to the business and operations of Purchaser or
such Purchasers Affiliate). For purposes of this provision, contribution history prior to the Closing Date with respect to any individual employee who is not a Continuing Employee shall be deemed attributable to the business and operations of
Seller if such employees services were performed primarily for the benefit of Seller, regardless of whether such individual employee was on Better Materials payroll or contributions were made on behalf of such employee under a collective
bargaining agreement to which Better Materials was a signatory. The contribution history with respect to the Continuing Employees shall be assumed by Purchaser as of the Closing Date.



8.5. Tax Matters. (a) Seller shall (i) cause the Company and each Subsidiary to be included in the consolidated federal income Tax Returns that include Seller for all periods for which they are eligible to be so included,
including without limitation the periods from January 1, 2003 through the Closing Date, and in any other required Tax Group Tax Returns for all periods ending on or before the Closing Date and (ii) timely prepare, or cause to be prepared, and file,
or cause to be filed, all such Tax Returns and (iii) timely pay when due, and indemnify and hold Purchaser harmless from, all Taxes relating to such Tax Returns. Seller shall timely prepare and file, or cause to be prepared and filed, all other Tax
Returns of the Company and each Subsidiary for all Taxable Periods ending on or prior to the Closing Date and timely pay, or cause to be paid, when due all Taxes relating to such Tax Returns. Any Tax Return described in the preceding sentence shall
be prepared or completed (w) by determining the items of income, expense, deduction, loss or credit on a closing of the books basis as of close of business on the Closing Date and (x) on a basis consistent with the elections, accounting
methods, conventions, and principles of taxation used for the most recent Taxable Periods for which Tax Returns have been filed, except as otherwise required by applicable Tax law or otherwise agreed to by the Purchaser prior to the filing thereof.
Seller agrees to provide the Company with a copy of (y) draft stand alone portions of each Tax Group Tax Return described in the first sentence of this Section 8.5(a) relating solely to the Company and each of its Subsidiaries and (z)
draft Tax Returns described in the second sentence of this Section 8.5(a), in each case, no later than 10 (ten) business days before the relevant Tax Return is due (taking into account extensions), and Seller shall, subject to its reasonable
judgment, incorporate thereon any reasonable comments timely provided in writing by the Company. The Tax Group Tax Returns described in the first sentence of this Section 8.5(a) shall be filed in a manner consistent with the draft stand
alone portions of the Tax Returns specified in clause (y), as adjusted for comments provided by the Company pursuant to the previous sentence.



(b) Any Taxes (other than those described in Section 8.5(a)) with respect to the Company or any Subsidiary that relate to a Taxable Period
beginning before the Closing Date and ending after the Closing Date (an Overlap Period) shall be apportioned between Seller and Purchaser, (i) in the case of Taxes not measured or measurable, in whole or in part, by net or gross
income or receipts, on a per diem basis, and (ii) in the case of other Taxes, as determined from the books and records of the Company or such Subsidiary during the portion of such

##### Table Of Contents

Taxable Period ending on the Closing Date and the portion of such Taxable Period beginning on the day following the Closing Date consistent
with the prior practice of Seller, the Company or the relevant Subsidiary with respect to the income, properties or operations of the Company or such Subsidiary. Purchaser shall cause the Company and each Subsidiary to file all Overlap Period Tax
Returns, and Purchaser shall pay, or cause to be paid, all Taxes shown as due on any such Tax Returns. If the Company and Subsidiaries are permitted under any applicable state or local income tax law to treat the Closing Date as the last day of a
taxable period, Purchaser and Seller shall treat (and cause their respective Affiliates to treat) the Closing Date as the last day of a taxable period. Seller shall pay the Purchaser, as an adjustment to the Purchase Price, its share of any such
Taxes due pursuant to the filing of any such Tax Returns under the provisions of this Section 8.5(b) (to the extent the Seller is liable therefor in accordance with this Section 8.5(b) and to the extent not already paid by the Seller, the Company or
any Subsidiary or accrued or otherwise reflected as a liability on the Final Closing Statement) within ten (10) business days of receipt of notice of such filing by Purchaser, which notice shall set forth in reasonable detail the calculations
regarding Sellers share of such Taxes; provided, however, that if, within ten (10) business days after receipt of such notice, Seller notifies Purchaser in writing that Seller disagrees with the computation of Sellers share
of such Taxes, Seller and Purchaser shall proceed in good faith to determine Sellers share of such Taxes. If Seller and Purchaser cannot agree in good faith on such share within thirty (30) days, Sellers share of such Taxes shall be
determined pursuant to Section 8.5(l). Sellers payment to Purchaser under this Section 8.5(b) shall be due ten (10) business days after the amount payable by Seller is determined by agreement between Seller and Purchaser or pursuant to Section
8.5(l). Seller shall pay interest on such amount at a rate per annum equal to the JP Morgan Chase Prime Rate as announced from time to time during the applicable period and accruing from the date that is ten (10) business days after receipt of
notice of filing by Purchaser until the date of payment.



(c) Purchaser shall be responsible for and shall indemnify and hold Seller harmless from all Taxes of the Company or any Subsidiary for any Taxable Period (or portion thereof) beginning on or after the Closing Date and for all Taxes
resulting from any election made by Purchaser under Section 338 of the Code with respect to the Company or any Subsidiary and actions taken outside the ordinary course of business and occurring on the Closing Date, which election was made or actions
taken without Sellers prior written consent.



(d) Seller shall have the exclusive right to represent the interests of the Company and each Subsidiary in any Tax audit or administrative or court proceeding relating to Returns described in Section 8.5(a); provided, however,
that the Purchaser shall have the right to participate in any such audit or proceeding to the extent that any such audit or proceeding may affect the Tax liability of Purchaser, the Company or any Subsidiary for any Taxable Period ending after the
Closing Date and to employ counsel of its choice at its own expense for purposes of such participation. Notwithstanding anything in this Agreement to the contrary, none of Purchaser or any of its affiliates (including the Company and any Subsidiary)
shall be entitled in any way to compromise, release, waive, settle, modify or pay any claim with respect to Taxes for which Seller may be liable under this Agreement, without prior written consent of Seller, which consent shall not be unreasonably
withheld or delayed. Without the prior written approval of Purchaser, which shall not be unreasonably withheld or delayed, neither Seller nor any affiliate of the Seller shall agree or consent to compromise or settle, either administratively or
after the commencement of litigation, any issue or claim arising in any such audit or proceeding,

##### Table Of Contents

or otherwise agree or consent to any Tax liability, to the extent that any such compromise, settlement, consent or agreement may increase the
Tax liability of Purchaser, the Company or any Subsidiary for any period ending after the Closing Date, unless Seller indemnifies Purchaser for the increase in Taxes resulting from such compromise, settlement, consent or agreement. Notwithstanding
any other provision of this Agreement, Seller shall have no obligation to pay or to indemnify or hold Purchaser, the Company or any Subsidiary harmless from any Tax imposed or assessed as a result of any action taken by Purchaser, the Company or any
Subsidiary with respect to any contest, audit, assessment or other proceeding without Sellers written consent, to the extent such written consent is required by this Agreement.



(e) Seller and Purchaser shall jointly agree on the conduct of any Tax audit or administrative or court
proceeding relating to Overlap Period Returns described in Section 8.5(b). Neither Purchaser nor Seller (or any of their Affiliates) shall be entitled in any way to compromise, release, waive, settle, modify or pay any claim with respect to Taxes
for which the other party may be liable under Section 8.5(b), without the prior written consent of such other party, which consent shall not be unreasonably withheld or delayed.



(f) Seller shall promptly notify Purchaser in writing upon receipt by Seller or any Affiliate of Seller of
notice of any pending or threatened Tax audits or assessments relating to the income, properties or operations of the Company or any Subsidiary. Purchaser shall promptly notify Seller in writing upon receipt of notice by Purchaser or any Affiliate
of Purchaser of any pending or threatened Tax audits for assessments relating to the income, properties or operations of the Company or any Subsidiary for any period ending on or before the Closing Date.



(g) Notwithstanding anything to the contrary contained or
implied in this Agreement, after the Closing Date, neither Purchaser nor any Affiliate of Purchaser (including the Company or any Subsidiary) shall, without the prior written consent of Seller, file or cause to be filed any amended Return or claim
for Tax refund with respect to the Company or any Subsidiary (or relating to their income, properties or operations) if any such filing may affect the Tax liability of Seller, the Company or any Subsidiary or their respective Affiliates for any
period ending on or before the Closing Date, except as may be required by law. Seller shall be entitled to any reductions in Taxes or Tax refunds (including interest) of or relating to the Company or any Subsidiary not received prior to the Closing
Date for Taxable Periods ending on or before the Closing Date to the extent Seller is obligated to indemnify Purchaser, the Company or any Subsidiary in respect of such Taxes. If Purchaser or its Affiliates (including the Company or any Subsidiary)
receives any such refund, Purchaser shall promptly pay (or cause to be paid) the entire amount of the refund (including interest) to Seller.



(h) After the Closing Date, Purchaser and Seller shall provide each other, and Purchaser shall cause the Company or any Subsidiary to
provide Seller, with such cooperation and information relating to the Company or any Subsidiary as any other party may reasonably request in (i) filing any Return or amended Return or claim for Tax refund, (ii) determining any Tax liability or right
to refund of Taxes, (iii) conducting or defending any audit or other proceeding in respect of Taxes, or (iv) effectuating the terms of this Agreement. The parties shall retain, and Purchaser shall cause the Company and each Subsidiary to retain, all
Returns, schedules and work papers, and all material records and other documents relating thereto with

respect to the Company and each Subsidiary, until the expiration of the statute of limitation (and, to the extent notified by any party, any
extensions thereof) with respect to the taxable years to which such Returns and other documents relate and, unless such Returns and other documents are offered and delivered to Seller or Purchaser, as applicable, until the final determination of any
Tax in respect of such years. Any information obtained under this Section 8.5 shall be kept confidential, except as may be otherwise necessary in connection with filing any Return, amended Return, or claim for refund of Taxes, determining any Tax
liability or right to refund of Taxes, or in conducting or defending any audit or other proceeding in respect of Taxes. Notwithstanding the foregoing, no party shall be unreasonably required to prepare any document, or determine any information, not
then in its possession in response to a request under this Section 8.5(h).

Tax sharing agreements or arrangements, express or implied, that exist between the Company and its Subsidiaries, on the one hand, and Seller or any of its Affiliates, on the other hand, and all obligations thereunder, shall, as to the Company and
its Subsidiaries, terminate as of the Closing Date, and the Company and its Subsidiaries shall have no liability for any amounts due in respect thereof for periods ending prior to or including the Closing Date.



(l) Any disputes between the parties with respect to this
Section 8.5 shall be resolved by a national public accounting firm or a law firm satisfactory to the Company and Seller, whose fees and expenses shall be shared equally between Company and Seller.

between Article 12 and this Section 8.5.



8.6.
Non-solicitation. (a) If this Agreement is terminated, Purchaser will not, for a period of two (2) years thereafter, directly or indirectly, solicit, induce or employ (except as provided below) any Person who is an
employee of Seller, the Company or any Subsidiary at the date hereof or at any time hereafter that precedes such termination, to terminate his or her employment with Seller, the Company or a Subsidiary; provided, however, that Purchaser may run
help wanted advertisements in newspapers of general circulation and may hire any former employee of Seller, the Company or a Subsidiary whose employment with Seller, the Company or a Subsidiary has terminated other than as a result of
Purchasers violation of this Section 8.6(a). Purchaser agrees that money damages will not be an adequate remedy and that Seller and the Company and each Subsidiary shall be entitled to equitable relief, including but not limited to injunction,
in the event of any breach by Purchaser of this Section 8.6, in addition to any other remedies available to Seller, the Company or any Subsidiary at law.

including reasonable attorneys, expert witnesses and accountants fees (Damages), whether or not incurred by
Purchaser or any Affiliate of Purchaser in connection with any action, suit, proceeding or claim against Seller hereunder, caused by or resulting or arising from or with respect to any (a) untruthfulness, inaccuracy or breach of any representation
and warranty of Seller hereunder as of the date hereof or as of the Closing Date (unless such representation or warranty speaks as of a specific date, in which case, only as of such date), (b) failures by Seller to perform or otherwise fulfill any
undertaking or agreement or obligation hereunder, (c) subject to Section 8.5, any Tax liability of the Company or any Subsidiary for taxable periods or portions of Overlap Periods ending on or prior to the Closing Date, which shall remain the sole
obligation of Seller, and (d) any Silicosis Liability; provided; however, that if any action, suit, proceeding, claim, liability, demand or assessment shall be asserted against any Purchaser Indemnitees in respect of which such
Purchaser Indemnitee proposes to demand indemnification, such Purchaser Indemnitee shall notify Seller thereof within a reasonable period of time after the Purchaser Indemnitee receives notice thereof; provided, further, that the
failure to so notify Seller shall not affect Purchasers right to indemnification hereunder except to the extent that Sellers interests are actually prejudiced thereby. Seller shall have the right within fifteen (15) days after receipt of
such notice to assume, at its sole cost and expense, the control of the defense, compromise or settlement of any such action, suit, proceeding, claim, liability, demand or assessment, including, employment of counsel. Purchaser shall have the right,
at its sole cost and expense, to participate in the defense of any such action, suit, proceeding, claim, liability, demand or assessment; provided, however, if (i) the named parties to any such proceeding (including any impleaded
parties) include both Purchaser (or a Purchaser Indemnitee) and Seller (or a Seller Indemnitee) and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them (other than
differing interests associated with Sellers obligation to indemnify), or (ii) the employment of counsel by such Purchaser Indemnitee has been authorized in writing by Seller, or (iii) Seller has not in fact employed counsel to assume the
defense of such action within a reasonable time; then, the Purchaser Indemnitee shall have the right to retain its own counsel (to be selected by the Purchaser Indemnitee and, in the case of (i) and (ii) above, consented to in writing by Seller,
such consent not to be unreasonably withheld or delayed), the reasonable fees and expenses of such counsel to be at the sole cost and expense of Seller. In such event, counsel selected by the Seller and the Purchaser Indemnitee shall be required to
cooperate in such defense, compromise or settlement and Purchaser will, at its own expense, make available to Seller those employees of Purchaser or any Affiliate of Purchaser (including but not limited to the Company or any Subsidiary) whose
assistance, testimony or presence, is necessary to assist Seller in evaluating and in defending any such action, suit, proceeding, claim, liability, demand or assessment; provided, however, that any such access shall be conducted in
such a manner as not to interfere unreasonably with the operations of the business of Purchaser and its Affiliates (including but not limited to the Company or any Subsidiary). Seller shall not compromise or settle any such action, suit, proceeding,
claim, liability or assessment without the written consent of Purchaser, which consent shall not be unreasonably withheld or delayed, if such compromise or settlement involves anything other than a payment of money and does not include a full and
unconditional release of the Purchaser Indemnitee from such action, suit, proceeding, claim, liability or assessment.

inaccuracy or breach of any representation and warranty of Purchaser hereunder as of the date hereof or as of the Closing Date (unless such representation or warranty speaks as of a specific date in which case, only as of such date), (b) failures by
Purchaser to perform or otherwise fulfill any undertaking or agreement or obligation of Purchaser hereunder or (c) subject to Section 8.5, any Tax liability of the Company or any Subsidiary for taxable periods or portions of Overlap Periods
beginning after the Closing Date, which shall be the sole obligation of Purchaser; provided, however, that if any action, suit, proceeding, claim, liability, demand or assessment shall be asserted against any Seller Indemnitee in
respect of which such Seller Indemnitee proposes to demand indemnification, such Seller Indemnitee shall notify Purchaser thereof within a reasonable period of time after the Seller receives notice thereof; provided, further, that the
failure to so notify Purchaser shall not affect such Seller Indemnitees right to indemnification hereunder except to the extent that Purchasers interests are actually prejudiced thereby. Purchaser shall have the right within fifteen (15)
days after receipt of such notice to assume, at its sole cost and expense, the control of the defense, compromise or settlement of any such action, suit, proceeding, claim, liability, demand or assessment, including employment of counsel. Seller
shall have the right, at its sole cost and expense, to participate in the defense of any such action, suit, proceeding, claim, liability, demand or assessment; provided, however, if (i) the named parties to any such proceeding
(including any impleaded parties) include both Seller (or a Seller Indemnitee) and Purchaser and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them (other than
differing interests associated with Purchasers obligation to indemnify), or (ii) the employment of counsel by such Seller Indemnitee has been authorized in writing by Purchaser, or (iii) Purchaser has not in fact employed counsel to assume the
defense of such action within a reasonable time; then, the Seller Indemnitee shall have the right to retain its own counsel (to be selected by the Seller Indemnitee and, in the case of (i) and (ii) above, consented to in writing by Purchaser, such
consent not to be unreasonably withheld or delayed), the reasonable fees and expenses of such counsel to be at the sole cost and expense of Purchaser. In such event, counsel selected by the Seller Indemnitee and the Purchaser shall be required to

evaluating and in defending any such action, suit, proceeding, claim, liability, demand or assessment; provided, however, that any such access shall be conducted in such a manner as not to interfere unreasonably with the operations of
the business of Seller and its Affiliates. Purchaser shall not compromise or settle any such action, suit, proceeding, claim, liability or assessment without the written consent of Seller, which consent shall not be unreasonably withheld or delayed,
if such compromise or settlement involves anything other than a payment of money and does not include a full and unconditional release of the Seller Indemnitee from such action, suit, proceeding, claim, liability or assessment.

##### Table Of Contents



(a) If the
Closing shall not have occurred, recovery of Purchaser and its Affiliates shall be limited to actual out of pocket expenses and shall in no event include any special, indirect, incidental or consequential damages whatsoever.



(b) Notwithstanding anything contained in Section 12.1,
Section 12.2 or otherwise, except with respect to Sections 5.3 (Capitalization of the Company), 5.4 (Equity Interests), 5.5(b) (Pettinos), 6.3 (Ownership) and Section 6.4 (Intercompany Claims) which shall survive indefinitely, after the expiration
of the representations and warranties as described in Section 11.1, neither Seller nor Purchaser shall have any further obligations under Section 12.1(a) and Section 12.2(a), except for claims for Damages in respect of which an indemnified party
(Indemnified Party) has given to the indemnifying party (Indemnifying Party) written notice prior to such dates.



(c) The amount of Damages otherwise recoverable by a Seller Indemnitee or Purchaser Indemnitee under this Article 12 shall be reduced to
the extent that any Federal, state, local or foreign tax liabilities of such Seller Indemnitee or Purchaser Indemnitee, as applicable, or any of their respective Affiliates, is decreased by reason of such Damages.



(d) Notwithstanding any other provision of this Agreement, the
determination of whether a breach has occurred and the amount of Damages otherwise recoverable by a Purchaser Indemnitee under Section 12.1(a) for breach of the representations or warranties contained in Sections 5.7 (Title to Real and Personal
Property; Condition of Assets), 5.9(a) (Compliance with Law), 5.9(c) (Permits), 5.15 (Environmental Matters) and 5.16(b) (Compliance with Labor Laws) shall be determined and calculated disregarding any materiality qualifiers contained therein.



(e) If any matters giving rise to a claim of
indemnification pursuant to this Article 12 by a Purchaser Indemnitee or Seller Indemnitee, as the case may be, may be covered by any insurance policy or policies, then Purchaser Indemnitee or Seller Indemnitee, as applicable, shall use reasonable
efforts to pursue the claim and obtain compensation from its insurer or insurers under such insurance policy or policies. If and when such compensation is actually received from such insurers for the matters giving rise to a claim of indemnification
(an Insurance Recovery), the Purchaser Indemnitee or Seller Indemnitee, as applicable, shall reduce such claim of indemnification against the Indemnifying Party to the extent of its Insurance Recovery (minus reasonable expenses incurred
in pursuing the claim with its insurer) or, if payment has already been made on such claim of indemnification, then the Indemnified Party shall remit the Insurance Recovery (minus reasonable expenses incurred in pursuing the claim with its insurer)
to the Indemnifying Party.



(f)



(i) No Damages arising out of a particular breach of any
representation or warranty hereunder on the part of Purchaser or Seller, as the case may be, that would otherwise be indemnified under Section 12.1(a) or 12.2(a), as the case may be, shall be recoverable by a Purchaser Indemnitee or Seller
Indemnitee pursuant to the provisions of this Article 12, and no claim therefor shall be asserted for any purpose hereunder (and, for the avoidance of doubt, no such Damages shall be counted towards the Indemnity Deductible),

unless the amount of such Damages (together with Damages arising out of any substantially related claims) exceeds $25,000, in which case the
entire amount of such Damages shall be recoverable pursuant to the provisions of this Article 12;



(ii) No Damages shall be recoverable by a Purchaser Indemnitee or Seller Indemnitee pursuant to the provisions of this Article 12 unless
and only to the extent that the amount of such Indemnitees Damages equals or exceeds $1,000,000 (the Indemnity Deductible) in the aggregate;



(g) The aggregate amount of Damages recoverable pursuant to the provisions of this Article 12 by Purchaser
Indemnitees and Seller Indemnitees, respectively, shall be limited to $10,000,000, respectively.

that Purchaser receives, at or after the Closing, pursuant to an adjustment to the Purchase Price for such Damages by reason of Article 4 hereof. For the avoidance of doubt, under no circumstances shall Damages include any amount paid by
Seller to Purchaser, or applied as a credit to the Purchase Price, in curing any state of facts that would otherwise prevent the fulfillment of any of the conditions precedent of Purchaser set forth in Article 10 hereof.



(j) If, after the delivery of any notice for indemnification
(Indemnification Notice) pursuant to this Article 12, the Indemnifying Party does not give written notice to the Indemnified Party disputing the Damages set forth in the Indemnification Notice (a Counter Indemnification
Notice) within 60 days after delivery of the Indemnification Notice, then the dollar amount of the Damages set forth in the Indemnification Notice shall be deemed conclusive for purposes of this Agreement. If after such 60-day period the
Indemnifying Party has failed to deliver a Counter Indemnification Notice, then the Indemnifying Party shall pay to the Indemnified Party the dollar amount of such Damages within 10 days after the expiration of such 60-day period.



(k) If a Counter Indemnification Notice is timely delivered to
the Indemnified Party, each party shall use their reasonable efforts to resolve such claim and agree upon a dollar amount, if any, applicable to such claim. If the parties cannot resolve such claim within 60 days after delivery of the Counter
Indemnification Notice, then the claim may be submitted to a court of competent jurisdiction. After a final decision in favor of the Indemnified Party has been

rendered by a court to enforce an award with respect to the amount of such claim, then the Indemnifying Party shall pay to the Indemnified
Party the full dollar amount of such claim within 10 days of such final decision.



(l) Without limiting the generality of Section 12.3(e) hereof and notwithstanding anything herein contained to the contrary, no Purchaser Indemnitee shall be entitled to assert a claim for
indemnification against Seller under this Article 12 for any Damages in respect of (i) any title matter that is insured by a title insurer as of the effective date of the applicable Title Policy or (ii) any title matter that would have been insured
by the title insurer, based upon the applicable Title Policy provided to Purchaser by the title insurer pursuant to Section 10.6 hereof, had Purchaser, in fact, purchased the applicable and available Title Policy. Seller and Purchaser expressly
understand and agree that Purchaser Indemnitees shall look solely to the title insurer with respect to a claim arising from a title matter as described in subparagraph (i) above and Seller shall have no liability or obligation of any kind with
respect to any claims arising from title matters described in subparagraphs (i) or (ii) above. In view of the fact that Purchaser and not Seller shall have selected the insurer issuing each of the Title Policies, Purchaser Indemnitees shall bear all
credit risk with respect to any insurer issuing a Title Policy, and Seller shall be relieved of all liability under this Article 12 even if Purchaser Indemnitee is unable to collect on a claim under any Title Policy due to the financial condition of
the title insurer. Purchaser Indemnitees shall use reasonable and diligent efforts to pursue any such claim against the title insurer and to obtain compensation therefrom.



12.4. Survival. Notwithstanding anything herein to the contrary, this Article 12 shall survive termination of this Agreement without limitation.



12.5. Sole Remedy. The provisions of this Article 12 shall provide the sole and exclusive remedy with respect to any and all Damages arising from the matters referred to in Section 12.1 or 12.2, as the case may be (except for
claims based on fraud). Nothing in this Section 12.5 shall limit or restrict the ability or right of any party hereto to seek injunctive or other equitable relief for any breach or alleged breach of this Agreement or any provision hereof.



12.6. Release.



(a)
Release by Seller Group of Purchaser, the Company and the Subsidiaries. Effective as of the Closing, Seller and each of the Persons listed on Schedule 12.6 (collectively, the Seller Releasors), hereby unconditionally and
irrevocably release and discharge the Company, the Subsidiaries and each Purchaser Indemnitee, including in each case their successors and assigns (collectively, the Purchaser Releasees), from all actions, causes of action, suits,
debts, dues, sums of money, accounts, reckonings, bonds, bills, specialties, covenants, contracts, controversies, agreements, promises, variances, trespasses, damages, judgments, extents, executions, claims, and demands whatsoever, in law, admiralty
or equity, which against the Purchaser Releasees (or any of them) the Seller Releasors (or any of them) and/or the successors and assigns of the Seller Releasors (or any of them) ever had, now have or hereafter can, shall or may have, for, upon or
by reason of any matter, fact or circumstance occurring or arising from the beginning of the world to the Closing; provided, that the foregoing shall not affect the rights of any party under this Agreement, or to enforce this Agreement or any other
agreement entered into in accordance herewith. Seller represents and warrants that

(b) Release by Purchaser, the Company and the
Subsidiaries of Seller. Effective as of Closing, Purchaser, the Company and the Subsidiaries (Purchaser Releasors), hereby unconditionally and irrevocably release and discharge the Seller and each of the Persons listed on
Schedule 12.6 (the Seller Releasees) from all actions, causes of action, suits, debts, dues, sums of money, accounts, reckonings, bonds, bills, specialties, covenants, contracts, controversies, agreements, promises, variances,
trespasses, damages, judgments, extents, executions, claims, and demands whatsoever, in law, admiralty or equity, which against the Seller Releasees (or any of them) the Purchaser Releasors (or any of them) and/or the successors and assigns of the
Purchaser Releasors (or any of them) ever had, now have or hereafter can, shall or may have, for, upon or by reason of any matter, fact or circumstance occurring or arising from the beginning of the world to the Closing; provided, that the foregoing
shall not affect the rights of any party under this Agreement, or to enforce this Agreement or any other agreement entered into in accordance herewith.



(c) Each of the Seller Releasors irrevocably covenants to refrain from, directly or indirectly, asserting any claim or demand, or
commencing, instituting or causing to be commenced, any proceeding of any kind against any Purchaser Releasee based upon any matter released pursuant to Section 12.6(a).



(d) Each of the Purchaser Releasors irrevocably covenants to refrain from, directly or indirectly, asserting
any claim or demand, or commencing, instituting or causing to be commenced, any proceeding of any kind against any Seller Releasee based upon any matter released pursuant to Section 12.6(b).



12.7. Determination of Breach of Certain Representations and Warranties.



Solely for the purpose of determining under 12.1(a) whether there exists any untruthfulness, inaccuracy or breach of any representation and warranty of Seller contained in Section 5.13 or Section 5.15
as of the date hereof or as of the Closing Date (unless such representation or warranty speaks as of a specific date, in which case, only as of such date) and for the purpose of determining the Damages with respect thereto, the phrase Since
October 1, 1999 in such sections shall be disregarded.



12.8. Right of Purchaser Indemnitee to Indemnification Unaffected by Other Sections.



For the avoidance of doubt, nothing contained in any Article of this Agreement other than this Article 12 (including, without limiting the
generality of the foregoing, anything contained in Section 10.16 of this Agreement) shall affect the right of Purchaser to make a claim for or obtain indemnification against Seller subsequent to the Closing Date in accordance with this Article 12.

13.5. Entire Agreement. This Agreement (including the Schedules and Exhibits attached hereto, all of which are a part hereof) contains the entire understanding of the parties hereto with respect to the subject matter contained
herein, and supersedes and cancels all prior agreements, negotiations, correspondence, undertakings and communications of the parties, oral or written, respecting such subject matter, including but not limited to the Descriptive Memorandum. There
are no restrictions, promises, representations, warranties, agreements or undertakings of any party hereto with respect to the transactions under this Agreement other than those set forth herein or made hereunder.



13.6. Amendments. This Agreement may be amended only by a written instrument executed by the parties or their respective successors or assigns.



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

13.8. Counterparts. This Agreement may be executed in one or more counterparts and each counterpart shall be deemed to be an original.



13.9. Parties in Interest; Assignment. Except as provided in or contemplated by Article 12 (which confers upon the Persons referred to therein for whose benefit it is intended the right to enforce such Article), nothing in this
Agreement, express or implied, is intended to confer upon any Person not a party to this Agreement any rights or remedies under or by reason of this Agreement. No party to this Agreement may assign or delegate all or any portion of its rights,
obligations or liabilities under this Agreement without the prior written consent of the other party to this Agreement; provided, however, that (i) Seller may assign this Agreement in connection with the sale of all or substantially
all of the business of Seller and (ii) Seller may grant a security interest in its rights under this Agreement to its lender(s) as security for Sellers obligations to such lender(s) (and such lender(s) may exercise its rights and remedies with

13.10. Severability; Enforcement. The invalidity of any portion hereof shall not affect the validity, force or effect of the remaining portions hereof. If it is ever held that any restriction hereunder is too broad to permit
enforcement of such restriction to its fullest extent, each party agrees that a court of competent jurisdiction may enforce such restriction to the maximum extent permitted by law, and each party hereby consents and agrees that such scope may be
judicially modified accordingly in any proceeding brought to enforce such restriction.



13.11. Jurisdiction. Each of Seller and Purchaser hereby irrevocably and unconditionally submits to the exclusive jurisdiction of the state and federal courts located in the Borough of Manhattan, The City of New York, for any
actions, suits, or proceedings arising out of or relating to this Agreement and the transactions contemplated hereby (and each of Seller and Purchaser agrees not to commence any action, suit or proceeding relating thereto except in such courts), and

court. Each of Seller and Purchaser hereby irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby, in such state or federal
courts as aforesaid and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.



13.12. Waiver. Any of the conditions to Closing set forth in this Agreement may be waived at any time prior to or at the Closing hereunder by the party entitled to the benefit thereof. The failure of any party hereto to enforce
at any time any of the provisions of this Agreement shall in no way be construed to be a waiver of any such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of such party thereafter to enforce each
and every such provision. No waiver of any breach of or non-compliance with this Agreement shall be held to be a waiver of any other or subsequent breach or non-compliance.



ARTICLE 14



GUARANTY BY SELLER GUARANTOR



14.1. Seller Guaranty.



(a) Seller Guarantor hereby guarantees, without any setoff or other deduction, the payment and performance when due of the Seller Guaranteed Obligations, without any limitation as to amount. Such guaranty is a continuing, absolute

direct or indirect, absolute or contingent, of Seller (or any successor of Seller or any transferee of all or substantially all of the assets of Seller) under this Agreement (including, but not limited to, the indemnification obligations set forth
in this Agreement). Each portion of the Seller Guaranteed Obligations heretofore or hereafter paid or satisfied by any money that has been heretofore or is hereafter received, applied or retained by Purchaser and is later recovered from Purchaser as

hereafter incurred by Purchaser as a result of any Claim. For purposes hereof, Claim means any claim, however asserted and whether now existing or hereafter arising, for the recovery of any money or other consideration heretofore or
hereafter received, applied or retained by Purchaser in payment or satisfaction of any of the Seller Guaranteed Obligations (including, but not limited to, any such claim involving any allegation that any money constituted trust funds or that the
receipt, application or retention of any money constituted a preference or fraudulent conveyance or transfer).



(c) Seller Guarantor shall pay to Purchaser on demand each cost and expense (including, but not limited to, if Purchaser retains counsel
for advice, litigation or any other purpose, reasonable attorneys fees and disbursements) hereafter incurred by Purchaser in endeavoring to enforce any obligation of Seller Guarantor pursuant to this Agreement or preserving or exercising any
right or remedy against Seller Guarantor pursuant to this Agreement or arising as a result of this Agreement, but only to the extent that such cost or expense would be recoverable from Seller.



(d) Seller Guarantor irrevocably waives, without any notice,
each right of subrogation, indemnification, reimbursement or contribution, and each similar right, against Seller heretofore or hereafter arising in connection with this Agreement or any of the Seller Guaranteed Obligations until Purchaser receives

(e) The guaranty provided for in this Section shall not be modified or terminated, no obligation of Seller Guarantor pursuant to this Agreement and no right or remedy of Purchaser against Seller Guarantor pursuant to this Agreement
or arising as a result of this Agreement shall be impaired or otherwise adversely affected, and no such right or remedy shall be waived by any act, omission or other thing, whether heretofore occurred or hereafter occurring. Except to the extent
expressly provided in this Agreement, Seller Guarantor irrevocably consents, without any notice, to each act, omission and other thing, whether heretofore occurred or hereafter occurring, that would or might, but for such consent, modify or
terminate Seller Guarantors obligations under this Agreement, impair or otherwise adversely affect any such obligation, right or remedy or operate as a waiver of any such right or remedy. Without limiting the generality of the preceding two
sentences, Seller Guarantors obligations hereunder shall not be modified or terminated by, no such obligation, right or remedy shall be waived by, and such consent shall apply to, whether heretofore occurred or hereafter occurring (i) any
extension, renewal, refinancing or other modification or replacement, assignment, compromise, cancellation, discharge, invalidity, impairment, unenforceability or change in any term or condition of, any defense with respect to, or any grant of any
participation in, any of the

forbearance from exercising, or any notice prior to exercising, any right or remedy of Purchaser relating to any of the Seller Guaranteed Obligations or against Seller, Seller Guarantor or any other Person, (iii) any case or other proceeding
pursuant to any bankruptcy, insolvency or similar statute with respect to Seller, Seller Guarantor or any other Person, (iv) any failure of any such claim to be allowed, in any case or other proceeding pursuant to any bankruptcy, insolvency or
similar statute, (v) the acceptance by Purchaser or any other Person of any writing intended by Seller or any other person to create an accord and satisfaction with respect to any of the Seller Guaranteed Obligations or any obligation of Seller,

of Seller or any other Person or (viii) any other circumstance that might otherwise constitute an equitable discharge of Seller Guarantor.



(f) Seller Guarantor irrevocably waives, without any notice, each act and other thing upon which, but for such waiver, any obligation of
Seller Guarantor pursuant to this Agreement or any right or remedy of Purchaser pursuant to this Agreement or arising as a result of this Agreement would or might be conditioned.

heretofore occurred or hereafter occurring, that would or might, but for such consent, modify or terminate Purchaser Guarantors obligations under this Agreement, impair or otherwise adversely affect any such obligation, right or remedy or
operate as a waiver of any such right or remedy. Without limiting the generality of the preceding two sentences, Purchaser Guarantors obligations hereunder shall not be modified or terminated by, no such obligation, right or remedy shall be
waived by, and such consent shall apply to, whether heretofore occurred or hereafter occurring (i) any extension, renewal, refinancing or other modification or replacement, assignment, compromise, cancellation, discharge, invalidity, impairment,
