	 	(a)	Agreement to Indemnify. 

 (i) Subject to the
limitations set forth in this Agreement, Wolverine, on the one hand, and Purchaser, on the other hand, (separately, the “Indemnifying Party”) shall indemnify, defend and hold the other (and the other’s respective officers, directors,
managers, employees, representatives, and agents) (collectively, the “Indemnified Parties”) harmless from and against, and shall pay to such persons and reimburse such persons for, any and all Damages arising, directly or indirectly, from
or in connection with: 
 (A) any breach of any representation and warranty of the Indemnifying Party contained in this
Agreement or in any certificate delivered at or in connection with the Closing; or 
 (B) any inaccuracy in any representation
and warranty of an Indemnifying Party contained in this Agreement as of the Closing Date, giving any effect to any written information delivered to the Indemnified Party at or before the Closing; or 
 (C) any breach or alleged breach of any covenant or agreement of the Indemnifying Party (or with respect to Wolverine, by Wolverine or

 (ii) The representations of Wolverine contained in Sections 4 and 5, on the one hand, and of Purchaser contained in Section 6, on the other hand, of this Agreement shall survive for a period of twelve
(12) months following the Closing Date; provided however, that in the event Wolverine Shanghai does not deliver it audited financial statements for the fiscal year ending December 31, 2008 to Wieland on or before

 CONFIDENTIAL 
  

 
(including the condition that the other party’s representations and warranties be true in all material respects) shall limit or otherwise affect its
rights to recover under this Agreement. 
 (iii) Notwithstanding the foregoing, any indemnification relating to any goods manufactured, sold,
marketed, or distributed or services provided by Wolverine Shanghai, Wolverine or its other Affiliates, or Purchaser or its Affiliates before the Closing shall not be governed by the terms and conditions of this Agreement, but shall be subject to
those of the Voting Rights Agreement. 
  

	 	(b)	Limitations on Indemnity. 

 Notwithstanding any
thing set forth in this Agreement to the contrary, no indemnification shall be required by Wolverine or Purchaser (or otherwise under this Agreement) unless the Indemnifying Party shall have received notice of a claim specifying the factual basis of
such claim in reasonable detail to the extent then known by the party making such claim on or before a date twelve (12) months after the Closing Date (or such later date as provided in Section 8(a)(ii). Except for claims
based upon fraud, gross negligence, or willful misconduct, the aggregate liability for all indemnification and reimbursement of related expenses described in this Section 8 which shall be paid by Wolverine or by Purchaser shall

any policy of insurance or similar contract. The provisions of this Section 8 shall survive expiration or termination of this Agreement for a period of twelve (12) months, except for claims that an Indemnifying Party receives
written notice of during such twelve (12) month period (or such later period as provided in Section 8(a)(ii)). 
  

	 	(c)	Procedure for Indemnification – Third-Party Claims. 

 (i) If any person shall claim indemnification hereunder arising from any claim or demand by any person (other than a party to this Agreement) against an Indemnified Party or the commencement of any litigation asserting a claim by an
independent party which may give rise to any indemnification to an Indemnified Party under the provisions of this Section 8 (a “Third Party Claim”), such Indemnified Party shall give to the party from whom
indemnification is sought (the “Indemnifying Party”) written notice of the basis for such claim or demand setting forth the nature of the claim or demand in reasonable detail, as promptly as is practicable after obtaining knowledge of such
claim, demand or litigation. The failure of the Indemnified Party to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any indemnification obligation hereunder except to the extent the Indemnifying Party which may
materially adversely affect the transactions contemplated by this Agreement or the other Transaction Documents. 
 (ii) If any Third Party
Claim Proceeding is brought against an Indemnified Party by a third party and the Indemnified Party gives notice to the Indemnifying Party pursuant to this Section 8, the Indemnifying Party shall, unless the claim involves taxes,
be entitled to participate in such Proceeding and, to the extent that it wishes, to assume the defense of such Proceeding, if (A) the Indemnifying Party provides written notice to the Indemnified Party that the Indemnifying Party intends to
undertake such defense and by such notice it shall be conclusively established that the Indemnifying Party shall indemnify the Indemnified Party against all claims for indemnification resulting from or relating to such third-party claim as provided
in this Section 8, (B) the Indemnifying Party conducts the defense of the Third-Party Claim actively and diligently with counsel reasonably satisfactory to the Indemnified Party and (C) if the Indemnifying Party is
a party to the Proceeding, the Indemnifying Party has not determined in good faith that joint representation would be inappropriate. The Indemnified Party shall, in its sole discretion, have the right to employ separate counsel (who may be selected
by the Indemnified Party in its sole discretion) in any such action and to participate in the defense thereof, and the fees and expenses of 

 CONFIDENTIAL 
  

 
such counsel shall be paid by such Indemnified Party. The Indemnified Party shall fully cooperate with the Indemnifying Party and its counsel in the defense
or compromise of such claim or demand, provided that all reasonable out-of-pocket expenses incurred by the Indemnified Party shall be paid by the Indemnifying Party (except the fees and expense of the Indemnified Party’s counsel as set forth in
the preceding sentence). If the Indemnifying Party assumes the defense of a Proceeding, the Indemnifying Party shall defend any such Third Party Claim in such manner as it may deem appropriate, including, without limitation, settling such Third
Party Claim or litigation (subject to the consent of the Indemnified Party, which shall not be unreasonably withheld), after giving the Indemnified Party reasonable notice of the same, on such terms as the Indemnifying Party may deem appropriate,
and the Indemnifying Party shall promptly reimburse the Indemnified Party in accordance with the provisions of this Section 8; provided that the Indemnifying Party shall furnish the Indemnified Party with copies of all pleadings
and other material documents in connection with any such Third Party Claim or Proceeding and the Indemnified Party shall be consulted about (although not in control of) such Third Party Claim or Proceeding. The Indemnified Party shall make available
to the Indemnifying Party such books and records as the Indemnifying Party may reasonably require in connection with such defense. If the Indemnifying Party assumes the defense of a Third Party Claim Proceeding, (X) no compromise or settlement
of the Third Party Claim may be effected by the Indemnifying Party without the Indemnified Party’s consent (which shall not be unreasonably withheld) unless (1) there is no finding or admission of any violation of law or any violation of
the rights of any Person by the Indemnified Party and such settlement has no adverse effect on any other claims that may be made against the Indemnified Party and (2) the sole relief provided is monetary damages that are paid by the
Indemnifying Party, and (Y) the Indemnified Party shall have no liability to the Indemnifying Party with respect to any compromise or settlement of such claims effected without its consent. 
 (iii) If (A) notice is given to an Indemnifying Party of the commencement of any Third Party Claim or a Proceeding by a third party making a claim
and the Indemnifying Party does not, within ten (10) days after the Indemnified Party’s notice is given, give notice to the Indemnified Party of the Indemnifying Party’s election to assume the defense of such claim or Proceeding or
(B) an Indemnified Party determines in good faith that there is a reasonable probability that a third party intends to commence a claim or Proceeding which may adversely affect it other than as a result of monetary damages for which it
would be entitled to indemnification from the Indemnifying Party under this Agreement, the Indemnified Party shall (upon notice to the Indemnifying Party) have the right to undertake the defense, compromise or settlement of such third party’s
claim; provided that the Indemnifying Party shall reimburse the Indemnified Party promptly and periodically for the costs of defending against such Third Party Claim (including reasonable attorneys’ fees and expenses) and the Indemnifying Party
shall remain responsible for any indemnifiable amounts arising from or related to such Third Party Claim. The Indemnifying Party may elect to participate in such third party claim Proceedings, negotiations or defense at any time at its own expense
and upon giving the Indemnified Party notice of its election to so participate, the Indemnified Party shall provide the Indemnifying Party with the pleadings, documents, books, and records and shall consult with the Indemnifying Party. 

(iv) With respect to any Third Party Claim subject to indemnification under this Section 8, (i) both the Indemnified Party and
the Indemnifying Party, as the case may be, shall keep the other person fully informed of the status of such Third Party Claim and any related Proceedings at all stages thereof if such person is not represented by its own counsel, and (ii) the
parties agree to render (each at its own expense) to each other such assistance as they may reasonably require of each other and to cooperate in good faith with each other in order to ensure the proper and adequate defense of any third-party claim.

 (v) With respect to any Third Party Claim subject to indemnification under this Section 8, the parties agree to
cooperate in such a manner as to preserve in full (to the extent possible) the 

 CONFIDENTIAL 
  

 
confidentiality of all confidential information and the attorney-client and work-product privileges. In connection therewith, each party agrees that:
(i) it will use commercially reasonable efforts, in respect of any Third Party Claim in which it has assumed or participated in the defense, to avoid production of confidential information (consistent with Applicable Law), and (ii) all
communications between any party hereto and counsel responsible for or participating in the defense of any Third Party Claim shall, to the extent possible, be made so as to preserve any applicable attorney-client or work-product privilege.

  

	 	(d)	Indemnification Procedure – Direct Claims. 

 If
an Indemnified Party shall claim indemnification pursuant to this Section 8 for any claim other than a Third Party Claim (a “Direct Claim”), the Indemnified Party shall notify the Indemnifying Party in writing of the
basis for such claim setting forth the nature and amount of the damages resulting from such claim. The Indemnifying Party shall give written notice of any disagreement with such claim within fifteen (15) days following receipt of the
Indemnified Party’s notice of the claim, specifying in reasonable detail the nature and extent of such disagreement. If the Indemnifying Party and the Indemnified Party are unable to resolve any disagreement as provided in
Section 9(a), then the parties hereto agree to arbitrate any direct claim for Damages as otherwise provided in Section 9.

legal principles consistent with the terms of this Agreement, and set forth the reason or reasons for its award. The Arbitration Panel shall have the authority to award equitable relief which shall be binding upon the parties to the arbitration
proceedings (including without limitation, enjoining the parties to the arbitration proceedings to take or refrain from taking specific action with respect to subject matter of the matter or disagreement); provided, however, no party
to the arbitration proceedings shall seek, and the Arbitration Panel shall have no authority to award, any punitive, special, or consequential damages or damages for lost business opportunity or for loss of profits relating to any matters under,
arising out of, or in connection with or relating to this Agreement or otherwise subject to arbitration. 
 (v) The Arbitration Panel shall
issue the arbitration award in New York, New York, and each party to this Agreement agrees that such award shall constitute a foreign arbitral award with respect to each country in which such party conducts business. The Arbitration Panel shall

such parties (including reasonable attorneys’ fees) and may award interest on any awards of the Arbitration Panel; provided, however, that each party to the arbitration proceedings shall pay its own costs associated with or
arising from the arbitration proceedings, unless the written arbitration award expressly provides otherwise. Until issuance of the arbitration award, the parties to this Agreement shall continue to perform this Agreement, and any other agreements or
instruments executed in connection with or in the performance of this Agreement, in accordance with their respective terms.

Information (including all 

 CONFIDENTIAL 
  

 
copies) which it has received from another party, and each party shall promptly comply with any such request from another party. Each party also shall
destroy all material prepared by it which is based upon any Confidential Information which it receives from another party; provided, however, a party who returns or destroys any Confidential Information which is material to its
performance of this Agreement or any other Transaction Document shall not have any liability for its failure thereafter to perform the terms and conditions of this Agreement to which such Confidential Information was material. If requested by
another party, a party (acting through one of its officers or directors) shall promptly certify in writing to the requesting party that such party has returned or destroyed all Confidential Information described in such request. 
 (ii) All Confidential Information shall be used by a party solely for the purposes of performing its obligations under this Agreement or another

any information regarding the terms and conditions of this Agreement or of any other Transaction Document or the fact of its or their respective existence, the party receiving such a request or requirement shall promptly give written notice to each
of the other parties to this Agreement or such other Transaction Document of such request or requirement so that such other parties shall have an opportunity to seek an appropriate protective order. The parties to this Agreement and the other
Transaction Documents shall cooperate to take reasonable steps to prevent disclosure of another party’s Confidential Information, including seeing an appropriate protective order, or if the information is required to be disclosed, confidential
treatment. The parties also agree that if, in the absence of a protective order, a party is legally required to disclose Confidential Information, the terms and conditions of this Agreement or another Transaction Document, the fact of this Agreement
or another Transaction Document, or other facts related to the activities contemplated by this Agreement or another Transaction Document, such party may disclose such information (including such Confidential Information) without liability under this
Agreement or such other Transaction Document, but such party shall not be relieved of any liability under this Agreement or such other Transaction Document for any previous disclosure by such party (or any of its officers, directors, employees,
representatives, or agents) which was not permitted by this Agreement. 
 (iv) This Section 11(p) shall survive the
termination of this Agreement for a period of five (5) years. 
 (q) Plain Meaning; Independent Review. This Agreement shall be
construed in its entirety according to its plain meaning and shall be construed as the product of negotiation at arms’ length between equally sophisticated business persons advised by counsel. Each party acknowledges that such party and its
attorneys have been given an equal opportunity to negotiate the terms and conditions of this Agreement and that any rule of construction to the effect that ambiguities are to be resolved against the drafting party or any similar rule operating
against the drafter of an agreement shall not be applicable to the construction or interpretation of this Agreement and this Agreement shall not be construed against the party who provided and drafted it.
