Employee agrees to comply with the Company’s Senior Leadership Team Stock Ownership Policy, which is attached as Exhibit 1, with respect to this award.

If for any reason the Employee does not acknowledge and accept this Agreement by 5:00 p.m. Milwaukee time on February 15, 2017, then (i) the Employee shall be considered to have declined the grant of the Restricted Stock Units, (ii) the Company’s grant of the Restricted Stock Units shall be deemed automatically rescinded and the Restricted Stock Units shall be null and void and (iii) the Employee’s acceptance of this Agreement after such time shall have no legal effect and the Company shall not be bound by any such acceptance.

Restriction Period. The “Restriction Period” with respect to each Restricted Stock Unit is the time between the Grant Date and the date such Restricted Stock Unit vests.

No Shareholder Rights Before Settlement. The Employee shall not be entitled to any rights or privileges of ownership of shares of Common Stock with respect to any Restricted Stock Unit unless and until a share of Common Stock is actually delivered to the Employee in settlement of such Restricted Stock Unit pursuant to this Agreement.

Dividends. On each payment date with respect to any dividend or distribution to holders of Common Stock with a record date occurring during a Restriction Period,

Settlement and Forfeiture of Units. Unless earlier forfeited, canceled, or settled pursuant to Paragraphs 5, 6, or 7, each Restricted Stock Unit shall be settled at the end of the Restriction Period applicable to such Restricted Stock Unit. Each Restricted Stock Unit settled pursuant to this Paragraph 5 shall be settled by delivery of one share of Common Stock.

If the Employee incurs a Termination of Employment, any Restricted Stock Units that remain outstanding and unvested as of the date of such Termination of Employment shall be forfeited, except as provided in Paragraphs 5(b), 6 or 7.

If such Termination of Employment is by reason of the Employee’s death or Disability, then any Restricted Stock Units that remain outstanding and unvested as of the date of such Termination of Employment shall become non-forfeitable and shall be settled as soon as practicable (but no more than thirty (30) days) after the Employee’s death or Disability. In the event of the Employee’s death, if the Employee fails to designate a beneficiary or the designated beneficiary of the Employee dies before the Employee dies or before the complete payment of the amounts payable under this Agreement, the amounts to be paid under this Agreement shall be paid to the legal representative or representatives of the estate of the last to die of the Employee and the beneficiary.

For purposes of this Agreement:

“Disability” means, (A) “Disability” as defined in any employment or similar agreement between Employee and the Company or a Subsidiary, or (B) if there is no such agreement or it does not define “Disability”, permanent and total disability as determined under the Company’s long-term disability plan applicable to Employee.

“Termination of Employment” means the termination of Employee’s employment with, or performance of services for, the Company and any of its Subsidiaries or Affiliates. Employee shall be deemed to incur a Termination of Employment without Cause if the Subsidiary or Affiliate by which Employee is employed, or for which Employee is performing services, ceases to be such a Subsidiary or an Affiliate, as the case may

Effect of the Merger. For purposes of this Paragraph 6, the “Merger” refers to the transactions contemplated by the Agreement and Plan of Merger by and among Joy Global Inc., Komatsu America Corp., Pine Solutions Inc. and Komatsu Ltd., dated as of July 21, 2016, including any subsequent amendment of that agreement (the “Merger Agreement”), and “Merger Closing Date” means the Closing Date defined in the Merger Agreement.

As of the Merger Closing Date, notwithstanding any other provision of this Agreement, each outstanding Restricted Stock Unit shall be converted into a long-term incentive award (a “Cash LTI Award”) that entitles the holder to receive, subject to the forfeiture provisions in Paragraphs 1, 5, and 6(b), a payment (in lieu of the holder’s Restricted Stock Units) in cash in an amount equal to, in the aggregate, the product of (i) the number of outstanding and unvested Restricted Stock Units as of immediately prior to the Merger, and (ii) $28.30. The portion of each Cash LTI Award that becomes vested on each applicable vesting date (including the date of a Termination of Employment described in subparagraph (b) below, if applicable) shall be paid within thirty (30) days following such vesting date.

In the event of a Termination of Employment without Cause or a Termination of Employment for Good Reason (each as defined below) during the Restriction Period following the Merger Closing Date, the Cash LTI Award shall become vested and non-forfeitable to the extent that results in the ratio of the amount of the original award that has vested to the full amount of the original award equaling the greater of (A) one third, and (B) the ratio of the total number of days that have elapsed from and including the Grant Date through the date of the Termination of Employment (not to exceed 1095) to 1095. Any portion of the Cash LTI Award that does not vest pursuant to the preceding sentence shall be forfeited immediately upon such Termination of Employment.

“Cause” means (A) conviction of Employee for committing a felony under U.S. federal or state law or an equivalent offense under the laws of any non-U.S. jurisdiction, (B) failure on the part of Employee to perform his or her employment duties in any material respect, or (C) Employee’s material violation of the written policies of the Company or a Subsidiary; provided that, termination of an employee’s employment pursuant to (B) or (C) in the previous sentence shall be considered to be with Cause only if (x) the Company provides notice to Employee of the

“Good Reason” means as defined in Employee’s employment agreement (ignoring the statement that “any good faith determination of Good Reason made by the Executive shall be conclusive”) provided that Employee’s resignation shall be considered to be for Good Reason only if (A) Employee provides notice to the Company of the act or omission constituting Good Reason within thirty (30) days following the occurrence of such act or omission, (B) the Company fails to remedy such act or omission within thirty (30) days following receipt of such notice, and (C) Employee resigns within thirty (30) days after the end of such cure period.

If the Merger Agreement is terminated without the occurrence of the Merger Closing Date, then the Committee may, in its sole discretion, (i) impose performance-based vesting conditions, determined by the Committee, on the unvested Restricted Stock Units outstanding as of such termination and/or (ii) cancel some or all of the unvested Restricted Stock Units outstanding as of such termination and replace such unvested Restrict Stock Units with other awards of similar value, as determined by the Committee, to be issued under the Plan.

Change in Control or Corporate Events. In the event of a Change in Control other than the Merger that occurs during the Restriction Period, the Restricted Stock Units will be treated in the manner determined by the Committee in accordance with the provisions of Section 10 of the Plan.

Event of Restatement.

If the Company restates any previously issued financial statements and such restatement is required as a result of the Company’s material noncompliance with any applicable financial reporting requirement under the federal securities laws:

the Employee shall pay to the Company any gain the Employee received in connection with the award under this Agreement to the extent, determined by the Board or Committee, that the Employee would have received less gain based upon the restated financial results, and “gain” for this purpose shall include the proceeds of any sale of stock of the Company, after the award has been settled; and

the amount of the award under this Agreement shall be reduced to the extent, determined by the Board or Committee, such amount would have been lower based upon the restated financial results.

The Company may seek recovery of the amounts due under subsection (a) by all legal means available, including, to the extent permitted by law, seeking direct repayment from the Employee, withholding such amount from other amounts owed by the Company to the Employee (or with respect to the Employee), and causing the cancellation of any outstanding incentive award.

The determination of the Board or Committee regarding the consequence of any event of restatement as described in this Paragraph 8 shall be final and conclusive. This Paragraph 8 does not affect the Company’s ability to pursue any and all available legal rights and remedies under governing law.

Nontransferability. Restricted Stock Units granted under this Agreement are not transferable by the Employee, whether voluntarily or involuntarily, by operation of law or otherwise, during the Restriction Period, except as provided in the Plan. Any assignment, pledge, transfer or other disposition, voluntary or involuntary, of the Restricted Stock Units made, or any attachment, execution, garnishment, or lien issued against or placed upon the Restricted Stock Units, except as provided in the Plan, shall be void.

Administration. This Agreement and the rights of the Employee hereunder are subject to all the terms and conditions of the Plan, as the same may be amended from time to time, as well as to such rules and regulations as the Committee may adopt for administration of the Plan. It is expressly understood that the Committee is authorized to administer, construe, and make all determinations necessary or appropriate to the administration of the Plan and this Agreement, all of which shall be binding upon the Employee.

Taxes and Withholdings. No later than the applicable date of settlement of the Restricted Stock Units, the Employee shall pay to the Company or make arrangements satisfactory to the Committee regarding payment of any federal, state, local, and applicable non-U.S. taxes, of any kind required by law to be withheld upon the settlement of such Restricted Stock Units, and the Company shall, to the extent permitted or required by law, have the right to deduct from any payment of any kind due to the Employee federal, state, local and applicable non-U.S. taxes of any kind required by law to be withheld upon the settlement of such Restricted Stock Units.

Confidential Information; Noncompetition; Nonsolicitation. Nothing in this Agreement limits the Company’s or its Affiliates’ rights with respect to the protection of trade secrets, confidential information, or customer or employee relationships as may be provided under law or under any other policy, code of ethics, employee handbook, or agreement between the Company or its Affiliates and the Employee. Instead, the covenants below shall supplement and be independent of any such rights. Each of the covenants below protects separate interests and is to be interpreted and applied independently of each other as well as any other covenant contained in this Agreement.

Employee Acknowledgments.

The Employee acknowledges that he or she will receive Confidential Information (as defined in subparagraph (b) below) in connection with his or her employment. The Employee also acknowledges that his or her employment may place him or her in contact, and in a position of trust, with customers of the Company or its Affiliates, and that in the course of employment the Employee may be given access to and asked to maintain and develop relationships with such customers. The Employee further acknowledges that the Company will invest substantially in providing Employee with highly specialized training in the business of the Company. The Employee acknowledges that such Confidential Information, customer relationships, and investment in Employee’s specialized training are of substantial value to the Company and its Affiliates, that this award of the Restricted Stock Units is designed to induce the Company and its Affiliates to share Confidential Information with the Employee and to further create incentives for the Employee to develop goodwill through customer relationships, and that it is reasonable for the Company to seek to protect its investment in Employee’s specialized training and to prevent the Employee from giving competitors access to Confidential Information and customer relationships.

The Employee acknowledges that the Company and its Affiliates have multi-national operations and competitors.

Confidential Information. The Employee shall hold in a fiduciary capacity for the benefit of the Company all secret or confidential information, knowledge or data relating to the Company or any of its Affiliates and their respective businesses that the Employee obtains during the Employee’s employment by the Company or any of its Affiliates and that is not public knowledge (“Confidential Information”). The Employee acknowledges that the Confidential Information is highly sensitive and proprietary and examples of such Confidential Information include, without limitation: product design information; product specifications and tolerances; manufacturing processes and methods; information regarding new product or new feature development; information regarding how to satisfy particular customer needs, expectations, and applications; information regarding strategic or tactical planning; information regarding pending or planned competitive bids; information regarding costs, margins, and methods of estimating; and information regarding key employees.

Company Property. All computer software, business cards, telephone lists, customer lists, price lists, contract forms, catalogs, records, files and know-how acquired while an employee of the Company or any of its Affiliates are acknowledged to be the property of the Company or the applicable Affiliate(s) and shall not be duplicated, removed from the possession or premises of the Company or such Affiliate(s) or made use of other than in pursuit of the business of the Company and its Affiliates or as may otherwise be required by law or any legal process, and, upon Termination of Employment for any reason, Employee shall deliver to the Company, or the applicable Affiliate, without further demand, all such items and any copies thereof which are then in his or her possession or under his or her control.

Noncompetition. During Employee’s employment and for the eighteen-month period following the Termination of Employment date, the Employee will not, within the geographic area where the Company or any of its Affiliates do business, except upon prior written permission signed by the President or an Executive Vice President of the Company in the case of a Termination of Employment, work for, consult with, or advise, directly or indirectly, as an employee, consultant, owner, partner, member, director, or officer, or make passive investments of more than three percent of the equity in, or otherwise engage in business with, any of the following, in a capacity where the Employee’s use of the goodwill described above in Paragraph 12(a)(i) or knowledge of trade secrets or other Confidential Information or use of specialized training of the Company or any of its Affiliates would be necessary in the performance of Employee’s job duties and reasonably likely to place the Company or any of its Affiliates at a competitive disadvantage: (i) the companies set forth on Exhibit 2, which are acknowledged by the Employee and the Company to be competitors of the Company or its Affiliates, or any of their successors or assigns; or, (ii) an entity controlled by, controlling or under common control with any company described in clause (i). Exhibit 2 is attached to and forms a part of this Agreement.

Nonsolicitation of Personnel. During Employee’s employment and for the two-year period following the Termination of Employment date, the Employee will not, directly or indirectly (i) solicit or induce for employment, or engagement as an independent contractor, on behalf of Employee or any other individual or organization, or (ii) be involved in any way on behalf of Employee or any other individual or organization in the hiring process of, any Company Employee.

Nonsolicitation of Customers. During Employee’s employment and for the one-year period following the Termination of Employment date, the Employee will not, directly or indirectly, endeavor to entice away from Company or any of its Affiliates, any person, firm, corporation, partnership or entity of any kind, if (i) such person or entity is a customer of the Company or any of its Affiliates, or was a customer of the Company or any of its Affiliates within one year prior to the Termination of Employment date, and (ii) (A) the Employee regularly performed services for, or regularly dealt with, or regularly had contact with such customer on behalf of the Company or any of its Affiliates, or (B) the Employee obtained knowledge, as a result of his or her position with the Company or any of its Affiliates, which would be beneficial to Employee’s efforts to convince such customer to cease doing business with the Company or any of its Affiliates, in whole or in part.

Noninterference with Business Relationships. During Employee’s employment and for the one-year period following the Termination of Employment date, the Employee will not, directly or indirectly, disrupt, or attempt to interfere with or disrupt, the business relationship between the Company or any of its Affiliates and any of its customers, suppliers, or employees.

Nondisparagement. The Employee will not make, publish, or communicate, or encourage others to make, publish, or communicate, to any person or entity or in any public forum any defamatory or disparaging remarks, comments, or statements concerning the Company or any of its Affiliates, any of their respective businesses, products, services or activities, or any of their respective current or former officers, directors, managers, employees or agents. This clause (i) shall not prohibit Employee from providing truthful testimony in response to a validly issued subpoena.

Required/Permitted Disclosures. Nothing in this Paragraph 12 or in this Agreement shall be construed to prevent disclosure of Confidential Information as may be required by applicable law or regulation, or pursuant to the valid order of a court of competent jurisdiction or an authorized government agency, provided that the disclosure does not exceed the minimum extent of disclosure required by such law, regulation or order. Employee shall promptly provide written notice of any such order to an authorized officer of the Company and provide all assistance Company reasonably requires to contest such law, regulation or order. Further nothing in this Agreement shall be construed as prohibiting Employee from reporting possible violations of law to a governmental agency or entity, or requiring Employee to seek authorization from the Company or to notify the Company if Employee makes such reports.

Forfeiture due to Breach. In the event of a breach of any of the Employee’s covenants under this Paragraph 12, the Restricted Stock Units (or the Cash LTI Award, if applicable) shall immediately be forfeited as of the date of such breach. The Employee acknowledges and agrees that such forfeiture is not expected to adequately compensate the Company and its Affiliates for any such breach and that such forfeiture shall not substitute for or adversely affect the remedies to which the Company or any of its Affiliates is entitled under Paragraph 12(l), at law, or otherwise.

Remedies. In the event of a breach of any of the Employee’s covenants under this Paragraph 12, the Employee shall return to the Company (i) any Common Stock obtained under this Agreement in exchange for the purchase price (if any) the Employee paid for such Common Stock, or (ii) if the Restricted Stock Units were converted into a Cash LTI Award prior to the breach, the amount of cash obtained under this Agreement. If the Employee has sold, transferred, or otherwise disposed of Common Stock obtained under this Agreement, the Company shall be entitled to receive from the Employee a cash payment equal to the fair market value of the Common Stock on the date of sale, transfer, or other disposition minus the purchase price (if any) paid by the Employee. Furthermore, in the event of a breach of any of the Employee’s covenants under this Paragraph 12, it is understood and agreed that the Company and any of its Affiliate(s) that employed the Employee shall be entitled to injunctive relief, as well as any other legal or equitable remedies that may be available. The Employee acknowledges and agrees that the covenants, obligations and agreements of the Employee in Paragraphs 12(a), (b), (c), (d), (e), (f), (g), (h), and (i) of this Agreement independently relate to special, unique and extraordinary matters and that a violation of any of the terms of such covenants, obligations or agreements will cause the Company irreparable injury for which adequate remedies are not available at law. Therefore, the Employee agrees that the Company and any of its Affiliate(s) that employed the Employee shall be entitled to an injunction, restraining order or such other equitable relief (without the requirement to post bond) as a court of competent jurisdiction may deem necessary or appropriate to restrain the Employee from committing any violation of such covenants, obligations, or agreements. These injunctive remedies are cumulative and in addition to any other rights and remedies that the Company or its Affiliates may have.

Jurisdiction. With respect to all disputes under this Paragraph 12, the Company and the Employee hereby irrevocably submit to the exclusive jurisdiction of the federal and state courts in the state or jurisdiction where the Employee’s primary office is located (or, if litigation is brought after the Termination of

Additional Acknowledgements. The Employee acknowledges that:

the limitations as to time, geographical area, and scope of activity to be restrained by Paragraph 12 are reasonable and acceptable to the Employee, and do not impose any greater restraint than is reasonably necessary to protect the trade secrets and other Confidential Information, goodwill, and other legitimate business interests of the Company and its Affiliates; and
