Each such notice will include the name of each applicable customer and the amount of each applicable payment and deduction.

(b) On the second Business Day following the end of each calendar month during such 12-month period: (i) if the amount of Misdirected Horizon Payments during the previous calendar month plus the amount of Misdirected TriMas Deductions during such month exceeds the amount of Misdirected TriMas Payments during such month plus the amount of Misdirected Horizon Deductions during such month, then TriMas will pay Horizon the amount of such difference and (ii) if the amount of Misdirected TriMas Payments during the previous calendar month plus the amount of

-25-

Misdirected Horizon Deductions during such month exceeds the amount of Misdirected Horizon Payments during such month plus the amount of Misdirected TriMas Deductions during such month, then Horizon will pay TriMas the amount of such difference.

(c) In the event that after the 12-month period following the Distribution, any member of the Horizon Group receives a Misdirected TriMas Payment or any member of the TriMas Group receives a Misdirected Horizon Payment, the receiving Party will return such payment to the applicable payor.

(d) During the 12-month period following the Distribution (or such shorter time as the Parties may agree in writing), Horizon will promptly upon receipt thereof forward to TriMas any invoice received by any member of the Horizon Group and addressed to any member of the TriMas Group, and TriMas will promptly upon receipt thereof forward to Horizon any invoice received by any member of the TriMas Group and addressed to any member of the Horizon Group (any invoice described in this sentence, a “Misdirected Invoice”). After such12-month period (or such shorter period as the Parties may agree in writing), each of TriMas and Horizon will return any Misdirected Invoices received by a member of their respective Groups to the applicable vendor for correction.

5.4Insurance Matters.

(a) Until the Distribution, each member of either Group will (i) cause itself and its employees, officers and directors to continue to be covered as insured Parties under existing policies of insurance and (ii) permit the members of the other Group and their respective employees, officers and directors to submit claims arising from or relating to facts, circumstances, events or matters that occurred at or prior to the Distribution, to the extent permitted under such policies. Except as provided in any Ancillary Agreement, from and after the Distribution, (A) no member of either Group will have responsibility to obtain coverage for any member of the other Group, (B) each member of either Group will have the right to remove any member of the other Group and its employees, officers and directors as insured Parties under any policy of insurance issued by any insurance carrier effective immediately following the Distribution and (C) neither Party will be entitled to make any claims for insurance coverage under the other insurance policies of the members of the other Group to the extent such claims are based upon facts, circumstances, events or matters occurring after the Distribution. No member of either Group will be deemed to have made any representation or warranty as to the availability of any coverage under any such insurance policy.

(b) After the Distribution, each member of each Group and each of their respective current, former and future directors, officers and employees, and each of the heirs, executors, successors and assigns of any of the foregoing, will have the right to assert claims arising from or relating to facts, circumstances, events or matters that occurred prior to the Distribution under any applicable insurance policies of the members of either Group to the extent permitted under the insurance policies up to the full available limits of such policies,provided that if the limits of any such policies

-26-

preclude payment in full of claims filed by a member of either Group, the insurance proceeds available under such policy will be paid to the respective Groups on a FIFO Basis. Where indemnification is not available underArticle VI, each member of each Group will be responsible for pursuing and administering its own insurance claims and any other member of either Group will provide such reasonable cooperation as is appropriate with respect to notice of those claims and otherwise, and, with respect to those claims, in the event any member of either Group elects to pursue insurance coverage through litigation or other action against an insurer, that member will be responsible for its own costs and fees in connection therewith.

(c) If any Asset transferred pursuant to this Agreement suffers or has suffered any damage, destruction or other casualty loss that arises or has arisen prior to the Distribution and for which no insurance claim has yet been made as of the Distribution, the Party who transferred the Asset will make a claim on any available insurance and pay any such proceeds to the Party who received the Asset.

(d) Nothing in this Agreement will prohibit any member of either Group from agreeing to modify or compromise insurance rights (including by means of commutation, novation, rescission, reformation, policy buyback or otherwise) with an insurer that has been placed in liquidation, rehabilitation, conservation, supervision or similar proceedings,provided that, where those insurance rights potentially also would have benefited any member of the other Group, whether by virtue of any indemnification obligations, by virtue of any insurance rights under the policy at issue, or otherwise, then Horizon and TriMas must both agree in advance and in writing to any modification or compromise of those insurance rights.

(c) Nothing contained inSections 6.1(a) or6.1(b) will impair any right of any Person to enforce this Agreement, any Ancillary Agreement, including the applicable Schedules hereto and thereto, or any arrangement that is not to terminate as of the Distribution, as specified inSection 2.3(b). In addition, nothing contained inSections 6.1(a) or6.1(b) will release any Person from:

(i) any Liability provided in or resulting from any Contract among any TriMas Entities and any Horizon Entities that is not to terminate as of the Distribution, as specified inSection 2.3(b), or any other Liability that is not to terminate as of the Distribution, as specified inSection 2.3(b);

(ii) any Liability assumed, transferred, assigned or allocated to the Group of which such Person is a member in accordance with, or any other Liability of any member of any Group under, this Agreement or any Ancillary Agreement; or

(iii) any Liability the release of which would result in the release of any Person other than a Person released pursuant to thisSection 6.1;provided that the Parties agree not to bring suit or permit any of their Subsidiaries to bring suit against any Person with respect to any Liability to the extent that such Person would be released with respect to such Liability by thisSection 6.1 but for the provisions of this clause (iii).

(d) Horizon will not make, and will not permit any other Horizon Entity to make, any claim or demand, or commence any Action asserting any claim or

-28-

demand, including any claim for indemnification, against any TriMas Entity, or any other Person released pursuant toSection 6.1(a), with respect to any Liabilities released pursuant toSection 6.1(a). TriMas will not, and will not permit any other TriMas Entity to, make any claim or demand, or commence any Action asserting any claim or demand, including any claim for indemnification, against any Horizon Entity, or any other Person released pursuant toSection 6.1(b), with respect to any Liabilities released pursuant toSection 6.1(b).

6.2Shared Liabilities.

(a) Each of TriMas and Horizon will be responsible for its Applicable Proportion of any Shared Liability. As set forth inSection 6.6(b)(ii) and subject toSection 6.6(b)(i), the costs and expenses relating to the defense and resolution of any Third-Party Claim that is a Shared Liability will be included in determining the obligations of the Parties with respect thereto pursuant to thisSection 6.2(a).

(b) TriMas will be responsible for managing, and will have the authority to manage, the defense and resolution (including settlement) of an Action with respect to a Shared Liability. TriMas will, when possible under the circumstances, (i) consult Horizon regarding the defense strategy with respect to any such Action, (ii) before agreeing to a settlement or other voluntary final disposition thereof, advise Horizon of the proposed terms of such disposition, and (iii) consider in good faith any alternative terms proposed by the Horizon. Notwithstanding the foregoing, Horizon will not be entitled to raise as a defense to its obligations to pay any amount in respect of any Shared Liability that it was not consulted in the response to or defense thereof (except to the extent such consultation was required under this Agreement), that its views or opinions as to the conduct of such response to or defense or the reasonableness of any settlement were not accepted or adopted, that it does not approve of the quality or manner of the response to or defense thereof or that such Shared Liability was incurred by reason of a settlement rather than by a judgment or other determination of liability.

(c) Any amount owed in respect of any Shared Liability (including reimbursement for the cost or expense of defense of any Third-Party Claim that is a Shared Liability) pursuant to thisArticle VI will be remitted within 30 calendar days after the Party entitled to such amount provides an invoice (including reasonable supporting information with respect thereto) to the Party owing such amount.

6.3Indemnification by Horizon. Subject to the provisions hereof, Horizon will, and will cause each other Horizon Entity (and each of their respective successors and assigns) to, jointly and severally indemnify, defend and hold harmless TriMas, each member of the TriMas Group, each of their respective past and present officers, directors and employees, each of their respective successors and assigns (collectively, the “TriMas Indemnified Parties”) from and against any and all Damages incurred or suffered by the TriMas Indemnified Parties arising out of or in connection with the following, whether such Damages arise or accrue prior to, on or following the Distribution Date:

(a) the Horizon Liabilities;

-29-

(b) any breach by any Horizon Entity of this Agreement or the Employee Matters Agreement (for the avoidance of doubt, any breach by a Party of the Tax Sharing Agreement and the Transition Series Agreement, will be subject to the provisions contained respectively therein); and

(c) any Guaranty Obligation.

6.4Indemnification by TriMas. Subject to the provisions hereof, TriMas will, and will cause each other TriMas Entity (and each of their respective successors and assigns) to, jointly and severally indemnify, defend and hold harmless Horizon, each member of the Horizon Group, each of their respective past and present officers, directors and employees, each of their respective successors and assigns (collectively, the “Horizon Indemnified Parties”) from and against any and all Damages incurred or suffered by the Horizon Indemnified Parties arising out of or in connection with the following, whether such Damages arise or accrue prior to, on or following the Distribution Date:

(a) the TriMas Liabilities; and

(b) any breach by any TriMas Entity of this Agreement or the Employee Matters Agreement (for the avoidance of doubt, any breach by a Party of the Tax Sharing Agreement and the Transition Series Agreement, will be subject to the provisions contained respectively therein).

6.5Claim Procedure.

(a) A Party that seeks indemnity under thisArticle VI (an “Indemnified Party”) will give written notice (a “Claim Notice”) to the Party from whom indemnification is sought (an “Indemnifying Party”), whether the Damages sought arise from matters solely between the Parties or fromThird-Party Claims. The Claim Notice must contain (i) a description and, if known, estimated amount (the “Claimed Amount”) of any Damages incurred or reasonably expected to be incurred by the Indemnified Party, (ii) a reasonable explanation of the basis for the Claim Notice to the extent of facts then known by the Indemnified Party, and (iii) a demand for payment of those Damages. No delay or deficiency on the part of the Indemnified Party in so notifying the Indemnifying Party will relieve the Indemnifying Party of any Liability or obligation hereunder except to the extent of any Damages caused by or arising out of such delay or deficiency.

(b) Within 30 calendar days after delivery of a Claim Notice the Indemnifying Party will deliver to the Indemnified Party a written response in which the Indemnifying Party will either: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount and, in which case, the Indemnifying Party will pay the Claimed Amount in accordance with a payment and distribution method reasonably acceptable to the Indemnified Party; or (ii) dispute that the Indemnified Party is entitled to receive all or any portion of the Claimed Amount, in which case, the Parties will resort to the dispute resolution procedures set forth inArticle VIII.

(c) In the event that the Indemnifying Party disputes the Claimed Amount, as soon as practicable but in no event later than 15 calendar days after the

-30-

receipt of the notice referenced inSection 6.5(b)(ii), the Parties will begin the process to resolve the matter in accordance with the dispute resolution provisions ofArticle VIII. Upon ultimate resolution thereof, the Parties will take such actions as are reasonably necessary to comply with such terms of resolution.

6.6Third-Party Claims.

(a) In the event that the Indemnified Party receives written notice or otherwise learns of the assertion by a Person who is not a member of either Group (a “Third Party”) of any claim or the commencement of any Action (collectively, a “Third-Party Claim”) with respect to which the Indemnifying Party may be obligated to provide indemnification under thisArticle VI, the Indemnified Party will give written notice to the Indemnifying Party of theThird-Party Claim. Such notification will be given within ten Business Days after receipt by the Indemnified Party of notice of suchThird-Party Claim, will be accompanied by reasonable supporting documentation submitted by such third Person (to the extent then in the possession of the Indemnified Party) and will describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for suchThird-Party Claim and the amount of the claimed Damages;provided,however, that no delay or deficiency on the part of the Indemnified Party in so notifying the Indemnifying Party will relieve the Indemnifying Party of any Liability or obligation hereunder except to the extent of any Damages caused by or arising out of such delay or deficiency.

(b) With respect to anyThird-Party Claim that is a Shared Liability:

(i) In accordance withSection 6.2(b), TriMas will control the defense and/or resolution, including settlement, of any Third-Party Claim that is a Shared Liability. Horizon will use commercially reasonable efforts to cooperate with TriMas in the defense of anyThird-Party Claim that is a Shared Liability.

(ii) TriMas’s costs and expenses of defending, and/or seeking to settle or compromise anyThird-Party Claim that is a Shared Liability will be included in the calculation of the amount of the applicable Shared Liability in determining the obligations of the Parties with respect thereto pursuant toSection 6.2.

(c) With respect to anyThird-Party Claim that is not a Shared Liability:

(i) Within 20 Business Days after delivery of such written notice, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of suchThird-Party Claim with counsel reasonably satisfactory to the Indemnified Party. During any period in which the Indemnifying Party has not so assumed control of such defense, the Indemnified Party will control such defense.

(ii) The Party not controlling such defense (the “Non-controlling Party”) may participate therein at its own expense;provided,however, that if the Indemnifying Party assumes control of such defense and the Indemnified Party concludes, upon the written opinion of counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to suchThird-Party Claim, the

-31-

reasonable fees and expenses of counsel to the Indemnified Party will be considered “Damages” for purposes of this Agreement. The Party controlling such defense (the “Controlling Party”) will keep theNon-controlling Party reasonably advised of the status of suchThird-Party Claim and the defense thereof and will consider in good faith recommendations made by theNon-controlling Party with respect thereto. TheNon-controlling Party will furnish the Controlling Party with such Information as it may have with respect to suchThird-Party Claim (including copies of any summons, complaint or other pleading which may have been served on such Party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and will otherwise cooperate with and assist the Controlling Party in the defense of suchThird-Party Claim.

(iii) The Indemnifying Party will not agree to any settlement of, or the entry of any judgment arising from, any suchThird-Party Claim without the prior written consent of the Indemnified Party, which consent will not be unreasonably withheld, conditioned or delayed;provided,however, that the consent of the Indemnified Party will not be required if (A) the Indemnifying Party agrees in writing to pay any amounts payable pursuant to such settlement or judgment, and (B) such settlement or judgment includes a full, complete and unconditional release of the Indemnified Party from further Liability. The Indemnified Party will not agree to any settlement of, or the entry of any judgment arising from, any suchThird-Party Claim without the prior written consent of the Indemnifying Party, which consent will not be unreasonably withheld, conditioned or delayed.

(d) If it has been Finally Determined that the Indemnified Party is entitled to indemnification, the Indemnifying Party will, upon request from the Indemnified Party, promptly pay to the Indemnified Party the amount of any expense, loss or other amount subject to indemnification resulting from theThird-Party Claim for which the Indemnifying Party’s responsibility has been so Finally Determined. If the Indemnified Party does not seek a determination pursuant to the immediately preceding sentence, then the Indemnifying Party will pay to the Indemnified Party in cash the amount, if any, for which the Indemnified Party is entitled to be indemnified under this Agreement within 20 Business Days after suchThird-Party Claim has been Finally Determined.

(e) The Indemnified Party will use reasonable best efforts to keep and maintain in force all insurance that applies to any claim for which indemnification is sought. The Indemnified Party will also use reasonable best efforts to ensure that Insurance Proceeds received with respect to claims, costs and expenses under insurance policies in force will be paid to reduce the net exposure of the Indemnified Party.

(f) From and after the Distribution, if an Action currently exists or is commenced by a Third Party with respect to which a Party (or any Affiliate of such Party) is a named defendant but such Action is a Liability allocated to the other Party under this Agreement or any Ancillary Agreement and is not a Shared Liability, then the other Party shall (i) use reasonable best efforts to cause such named Party to be removed from such Action and (ii) if such other Party is not a named defendant on such Action, endeavor to substitute itself for the named Party.

-32-

6.7Indemnification Obligations Net of Insurance Proceeds and Other Amounts.

(a) The amount of any Damages for which indemnification is provided under this Agreement will be net of any amounts actually recovered by the Indemnified Party from any Third Party (including Insurance Proceeds actually recovered) with respect to such Damages. An Indemnifying Party will be subrogated to the rights of the Indemnified Party upon payment in full of the amount of the relevant indemnifiable Damages. An insurer who would otherwise be obligated to pay any claim will not be relieved of the responsibility with respect thereto or have any subrogation rights with respect thereto, in either case, solely by virtue of the indemnification provisions of this Agreement. If any Indemnified Party recovers an amount from a Third Party in respect of Damages for which indemnification is provided in this Agreement after the full amount of such indemnifiable Damages has been paid by an Indemnifying Party or after an Indemnifying Party has made partial payment of such indemnifiable Damages and the amount received from the Third Party exceeds the remaining unpaid principal balance of such indemnifiable Damages, then the Indemnified Party will promptly remit to the Indemnifying Party the excess (if any) of (i) the sum of the amount theretofore paid by such Indemnifying Party in respect of such indemnifiable Damagesplus the amount received from the Third Party in respect thereof,less (ii) the full amount of such indemnifiable Damages, andless (iii) the amount of any Taxes payable by the Indemnified Party with respect to any sums paid to the Indemnified Party described in clause (i) above that are treated as taxable income to the Indemnified Party.

(b) In the case of any Shared Liability, any Insurance Proceeds actually received, realized or recovered by any Party in respect of the Shared Liability will be shared between the Horizon Group and the TriMas Group in accordance with their respective Applicable Proportions, regardless of which Group may actually receive, realize or recover such Insurance Proceeds.

(c) Notwithstanding anything to the contrary in thisArticle VI, but subject toSection 6.7(a) above, in the event that a Horizon Entity is an Indemnifying Party:

(i) The initial presumption for purposes of calculating indemnity payments will be that there is no insurance coverage for any such Damages, and the Indemnifying Party will, upon request by any TriMas Indemnified Party,re-affirm in writing to fully indemnify, defend and hold harmless the Indemnified Party from and against any and all such Damages. Once the Indemnifying Party hasre-affirmed this obligation to the Indemnified Party in writing, the Indemnifying Party may at any time request that the Indemnified Party pursue insurance coverage from one or more insurers in connection with such Damages.

(ii) If requested, the Indemnified Party will cooperate in good faith with the Indemnifying Party and use reasonable best efforts to pursue insurance

-33-

coverage, including, if necessary, the filing of coverage litigation, after consultation with the Indemnifying Party and the Indemnifying Party has provided written consent as to the initiation of coverage litigation (which consent will not be unreasonably withheld, conditioned or delayed), all of which will be at the Indemnifying Party’s sole cost and expense. The Indemnifying Party will pay directly, or promptly reimburse the Indemnified Party for, all such costs and expenses, as directed by the Indemnified Party.

(iii) The Indemnified Party will retain full and exclusive control of all such matters (including the settlement of coverage claims against insurers), and the Indemnified Party will have the right to select counsel with the concurrence of the Indemnifying Party, which concurrence will not be unreasonably withheld, conditioned or delayed.

(iv) The proceeds of any insurance recovery (after deducting the insurance indemnity payment for the settlement or judgment for which coverage was sought, and any costs and expenses that have not yet been paid or reimbursed by the Indemnifying Party) will be paid to the Indemnifying Party.

(v) At all times, the Indemnifying Party will cooperate with the Indemnified Party’s insurers and/or with the Indemnified Party in the pursuit of insurance coverage, as and when reasonably requested to do so by the Indemnified Party.

(vi) It is not the intent of thisSection 6.7(c) to absolve the Indemnifying Party of any responsibility to the Indemnified Party for those Damages in connection with which the Indemnified Party actually secures insurance coverage, but to allocate the costs of pursuing such coverage to the Indemnifying Party and to provide the Indemnified Party with a full, interim indemnity from the Indemnifying Party until such time as the extent of insurance coverage is determined and is obtained. It is also not the intention of thisSection 6.7(c) that the indemnity obligations of the Indemnifying Party should be viewed as “additional insurance” by any insurer.

(vii) Notwithstanding anything to the contrary in thisSection 6.7(c), the Indemnified Party in its sole discretion may pursue insurance coverage for the benefit of the Indemnifying Party before the Indemnifying Party has requested it to do so. In such event, the Indemnified Party may unilaterally take any steps it determines to be necessary to preserve such insurance coverage, including, by way of example and not by way of limitation, tendering the defense of any claim or suit to an insurer or insurers of the Indemnified Party if the Indemnified Party concludes that such action may be required by the relevant insurance policy or policies. Any such actions by the Indemnified Party will not relieve the Indemnifying Party of any of its obligations to the Indemnified Party under this Agreement, including the Indemnifying Party’s obligation to pay directly, or reimburse the Indemnified Party for, costs and expenses.

(viii) For purposes of thisSection 6.7(c), the following will not be considered insurance available to any Horizon Group members as an Indemnifying Party: (A) any deductible payable by the Indemnified Party; (B) any retention payable by the Indemnified Party; (C) anyco-insurance payable by the Indemnified Party; and (D)

-34-

any coverage that ultimately will be payable or reimbursable by the Indemnified Party through any arrangement, including aninsurance-fronting arrangement or fronted insurance policy.

(ix) It is the intention of thisSection 6.7(c) to make insurance available to the Indemnifying Party only in those instances in which there has been a final transfer of the risk to a solvent third-party commercial insurer.

6.8Indemnification Obligations Net of Taxes. For all Tax purposes, TriMas and Horizon agree to treat any indemnification payment paid pursuant to thisArticle VI as either a contribution made by TriMas to Horizon or a distribution made by Horizon to TriMas, as the case may be, occurring immediately prior to the Distribution Date, except as otherwise required by applicable Law or a Final Determination (as defined in the Tax Sharing Agreement);provided,however, that in the event it is determined that such treatment is not permissible or if an Indemnified Party otherwise suffers a Tax detriment as a result of receiving such payment, the payment shall be increased to place the Indemnified Party in the same after Tax position as if the payment had been treated as intended under thisSection 6.8. In addition, any indemnification payment paid pursuant to thisArticle VI will be decreased to take into account any reduction in taxable income of the Indemnified Party arising from the payment by the Indemnified Party of such indemnified liability (“Tax Benefits”). For purposes of thisSection 6.8, any Tax Benefit will be determined (i) using the highest applicable marginal U.S. federal corporate income tax rate in effect at the time of the determination (and excluding any state income tax effect of such inclusion or reduction) and (ii) assuming that the Indemnified Party will be liable for Taxes at such rate, the Indemnified Party has sufficient taxable income to use any tax deduction, and has no other relevant Tax Attributes (as defined in the Tax Sharing Agreement) at the time of the determination.

6.9Cumulative Remedies; Limitations of Liability.

(a) The remedies provided in thisArticle VI are cumulative and will not preclude any Indemnified Party from asserting any other rights or from seeking any and all other remedies against any Indemnifying Party, except that the remedies provided in thisArticle VI will be the exclusive remedy for claims for contribution or other rights of recovery arising out of or relating to any Environmental Law, including the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), whether now or hereinafter in effect.

(b) NotwithstandingSection 6.9(a), neither Horizon or its Affiliates, on the one hand, nor TriMas or its Affiliates, on the other hand, will be liable to the other for any special, indirect, punitive, exemplary, remote, speculative or similar damages in excess of compensatory damages of the other arising in connection with the Separation,provided that any Liability with respect to a Third-Party Claim will be considered direct damages.

6.10Survival of Indemnities. The rights and obligations of each of Horizon or TriMas and their respective Indemnified Parties under thisArticle VI will survive any Party’s sale, merger or transfer of any Assets or businesses or assignment of any Liabilities.

-35-

ARTICLE VII

EXCHANGE OF INFORMATION; LITIGATION MANAGEMENT; CONFIDENTIALITY

7.1Agreement for Exchange of Information. From time to time as reasonably requested by either Party following the Distribution, the Party receiving the request will deliver to the requesting Party, at the expense of the requesting Party: (a) any corporate books and records of any member of the requesting Party’s Group in the possession of the Party receiving the request or any member of its Group and (b) originals or copies of any corporate books and records of the Group of the Party receiving the request that primarily relate to the requesting Party’s Business, its Assets or its Liabilities. From and after the Distribution, all such books, records and copies (where copies are delivered in lieu of originals), whether or not delivered, will be the property of the members of the requesting Party’s Group;provided,however, that all such Information contained in such books, records or copies relating to the other Party’s Group will be subject to the applicable confidentiality provisions and restricted use provisions, if any, contained in this Agreement or the Ancillary Agreements and any confidentiality restrictions imposed by applicable Law. Each Party may retain copies of any original books and records delivered to the other Party pursuant to thisSection 7.1;provided,however, that all such Information contained in such books, records or copies (whether or not delivered to the requesting Party) relating to the requesting Party’s Group will be subject to the applicable confidentiality provisions and restricted use provisions, if any, contained in this Agreement or the Ancillary Agreements and any confidentiality restrictions imposed by applicable Law.

7.2Access to Information. In addition to the provisions set forth inSection 7.1 and except in the case of an adversarial Action or threatened adversarial Action by any member of one Group against any member of the other Group (which will be governed by such discovery rules as may be applicable thereto), from and after the Distribution and upon reasonable notice, a member of either Group may request, on behalf of itself or its representatives, at the expense of the requesting Party, reasonable access and duplicating rights during normal business hours to all Information developed or obtained prior to the Distribution within the possession of any member of the other Group and to the personnel of any member of the other Group, in each case, to the extent such access relates to the requesting Party or its Business, its Assets or Liabilities, this Agreement or any Ancillary Agreement. In each case, the requesting Party will cooperate with the other Party to minimize the risk of unreasonable interference with the other Party’s business. The Party receiving the request will have the right to deny access to the Information if such Party determines in its good faith that the exchange of such Information is reasonably likely to violate any Law or Contract, or waive or jeopardize anyattorney-client privilege or attorney work product protection;provided,however, that the Parties will, and will cause their respective Subsidiaries to, take all reasonable measures to permit the sharing of such Information in a manner that avoids any such harm or consequence. In the event access is granted to any Information in this Agreement or in the Ancillary Agreements to which access is restricted by Law or otherwise, the Parties will, and will cause their respective Subsidiaries to, take such

-36-

actions as are reasonably necessary, proper or advisable to have such restrictions removed or to seek an exemption therefrom or to otherwise provide the requesting Party with the benefit of the Information to the same extent such actions would have been taken on behalf of the requesting Party had such a restriction not existed and the Distribution not occurred.

7.3Litigation Management and Support; Production of Witnesses.

(a) From and after the Distribution, Horizon (or other applicable member of the Horizon Group) will be responsible for managing, and will have the authority to manage, the defense or prosecution, as applicable, and resolution (including settlement) of any Horizon Litigation and TriMas (or other applicable member of the TriMas Group) will be responsible for managing, and will have the authority to manage, the defense or other prosecution, as applicable, and resolution (including settlement) of any TriMas Litigation.

(b) Notwithstanding any provisions ofSection 7.2 to the contrary, after the Distribution, each member of the Horizon Group and the TriMas Group will use reasonable best efforts to assist the other with respect to anyThird-Party Claim or potentialThird-Party Claim. In addition, any member of either Group will have the right to request in writing that a member of the other Group make available for consultation or witness purposes, its directors, officers, employees, consultants or agents who have expertise or knowledge with respect to the other Party’s business or products or matters in litigation or alternative dispute resolution to the extent that the requesting Party believes any such persons may reasonably be useful or required in connection with any legal, administrative or other proceedings in which the requesting Party may from time to time be involved. Upon such request, the affected members of the applicable Group will select such person or persons to provide the requested assistance after conferring in good faith to determine which person or persons should provide such assistance. Upon such determination, the requested Party agrees to make the designated person or persons available to the requesting Party upon reasonable notice to the same extent such requested Party would have made such person available if the Distribution had not occurred. The requesting Party agrees to cooperate with the requested Party in giving consideration to such persons’ business demands.

7.4Reimbursement. Except to the extent otherwise contemplated by this Agreement or any Ancillary Agreement, the Party requesting Information, consulting or witness services under thisArticle VII will reimburse the recipient for the reasonable and documented costs and expenses, if any, incurred in providing such Information, consulting or witness services to the requesting Party.

7.5Retention of Records. Except as otherwise required by Law or agreed in writing, or as otherwise provided in any Ancillary Agreement, each member of the Horizon Group and the TriMas Group will use reasonable best efforts to retain, for the retention periods set forth in its record retention policy as in effect on the Distribution Date or as amended after the Distribution Date in accordance with the following sentence (but in no event for a period longer than ten years after the Distribution Date), except for such longer period as required by Law, this Agreement or the Ancillary

-37-

Agreements, all Information in such Party’s possession substantially relating to the other Party or its Business, its Assets or Liabilities, this Agreement or the Ancillary Agreements (the “Retained Information”). Each member of the Horizon Group or the TriMas Group may amend its record retention policy after the Distribution Date so long as (a) the amended policy complies with applicable Law, (b) the amended policy treats the Retained Information in the same manner as such member’s other Information and (c) the amended policy does not allow for the destruction of any Retained Information prior to the earliest date after the Distribution on which such member would have been able to destroy such Retained Information under the policy in effect as of the Distribution. If any member of either Group amends its record retention policy in compliance with the preceding sentence in a manner that reduces the retention period for any Retained Information, it will provide Horizon, in the case of any such amendment by a member of the TriMas Group, or TriMas, in the case of any such amendment by any member of the Horizon Group, written notice detailing the changes to the record retention policy, and the Party receiving such notice and the members of its Group will have the opportunity to obtain any Retained Information that would be eligible for destruction under the revised policy at least 90 calendar days prior to the destruction of such Retained Information.

(a) Each of Horizon (on behalf of itself and the other Horizon Entities) and TriMas (on behalf of itself and the other TriMas Entities) acknowledges that:

(ii) actual, threatened or future litigation, investigations, proceedings (including arbitration proceedings), claims or other legal matters have been or may be asserted by or against, or otherwise affect, some or all members of the Horizon Group or the TriMas Group (“Litigation Matters”);

(iii) members of the Horizon Group and the TriMas Group have or may in the future have a common legal interest in Litigation Matters, in the Privileged Information and in the preservation of the protected status of the Privileged Information; and

(iv) each of Horizon and TriMas (on behalf of itself and the other members of its Group) intends that the transactions contemplated by this Agreement and the Ancillary Agreements and any transfer of Privileged Information in connection herewith or therewith will not operate as a waiver of any applicable privilege or protection afforded Privileged Information.

(b) Each of Horizon and TriMas agrees, on behalf of itself and each member of the Group of which it is a member, not to disclose knowingly or otherwise

-38-

waive any privilege or protection attaching to any Privileged Information relating to a member of the other Group or relating to or arising in connection with the relationship between the Groups prior to the Distribution, without providing prompt written notice to and obtaining the prior written consent of the other.

(c) Upon any member of the Horizon Group or the TriMas Group receiving any subpoena or other compulsory disclosure notice from a Governmental Authority that requests disclosure of Privileged Information belonging to a member of the other Group, the recipient of the notice will promptly provide to TriMas, in the case of receipt by a member of the Horizon Group, or to Horizon, in the case of receipt by a member of the TriMas Group, a copy of such notice, the intended response and all materials or information relating to the other Group that might be disclosed. In the event of a disagreement as to the intended response or disclosure, unless and until the disagreement is resolved as provided inArticle VIII, the members of the Horizon Group and the TriMas Entities will cooperate to assert all defenses to disclosure claimed, at the cost and expense of the members of the Group claiming such defenses to disclosure, and will not disclose any disputed documents or information until all legal defenses and claims of privilege have been Finally Determined.

7.7Confidentiality.

(a) From and after the Distribution, each of the Parties will use reasonable best efforts to hold, and will cause the other members of its Group to hold, in strict confidence, all business sensitive or proprietary Information concerning or belonging to the members of the other Group (such Information, “Confidential Information”) obtained by it prior to the Distribution or furnished to it by any member of the other Group pursuant to this Agreement or any Ancillary Agreement. Neither Party will (and each Party will cause the other members of its Group not to) disclose any Confidential Information to any other Person, except (i) to the extent that disclosure is compelled by subpoena or other compulsory disclosure notice from a Governmental Authority or, in the opinion of TriMas’s or Horizon’s counsel (as the case may be), by other requirements of Law, but only after compliance withSection 7.7(b), (ii) to the extent such Party can show that such Confidential Information was (A) in the public domain through no fault of such Party or any member of such Group or any of its respective directors, officers, employees, agents, accountants, counsel and other advisors and representatives, (B) later lawfully acquired from other sources by such Party (or any member of such Party’s Group), which sources are not themselves bound by a confidentiality obligation or (C) independently generated without reference to any proprietary or confidential Information of the disclosing Party or the other members of its Group or (iii) to its directors, officers, employees, agents, accountants, counsel and other advisors and representatives who need to know such Information (who will be advised of their obligations hereunder with respect to such Information in advance of its disclosure to such persons). Neither Party will (and each Party will cause the other members of its Group not to) use any Confidential Information for any purpose other than for which it was disclosed by any member of the other Group.

(b) Upon any member of the Horizon Group or the TriMas Group receiving any subpoena or other compulsory disclosure notice from a Governmental

In the event that such appropriate protective arrangements are not obtained, the Person that is required to disclose such Confidential Information will furnish, or cause to be furnished, only that portion of such Confidential Information that is legally required to be disclosed and will use reasonable best efforts to ensure that confidential treatment is accorded such Confidential Information.

(c) When any Information concerning the other Group or its Business is no longer needed for the purposes contemplated by this Agreement or any Ancillary Agreement, each Party will, and will cause the members of its Group to, promptly after request of the other Party, use reasonable best efforts to destroy all such Information.

ARTICLE VIII

DISPUTE RESOLUTION

8.1Dispute Process.

(a) The Parties will use commercially reasonable efforts to resolve expeditiously and on a mutually acceptable negotiated basis any dispute or disagreement between the Parties arising out of or relating to this Agreement or any Ancillary Agreements (other than a Third-Party Claim) (a “Dispute”) exclusively (except as otherwise expressly provided in this Agreement) as follows: (i) first, by engaging in an informal dispute resolution process with the possibility of mediation as provided inSection 8.2; and (ii) then, if negotiation and mediation fail, by referring the Dispute to binding arbitration as provided inSection 8.3. Each Party agrees on behalf of itself and each member of its respective Group that the procedures set forth in thisArticle VIII will be the exclusive means for resolution of any Dispute. The initiation of informal dispute resolution or arbitration hereunder will toll the applicable statute of limitations for the duration of any such proceedings.

(b) Within five Business Days after the date hereof TriMas and Horizon will form a steering committee (the “Steering Committee”), which will be comprised of four members, two of whom will be appointed by TriMas and two of whom will be appointed by Horizon. The Parties will use commercially reasonable efforts to cause their respective members of the Steering Committee to make a good faith effort to promptly (i) resolve all Disputes referred to the Steering Committee pursuant toSection 8.2. Steering Committee decisions made with the consent of at least three members will be binding on TriMas, Horizon and their respective Group members.

8.2Informal Dispute Resolution.

(a) A Dispute will first be referred to the Steering Committee for resolution. In the event of a Dispute, the Party seeking recourse must first send notice of the Dispute (a “Dispute Notice”) to the other Party (i) reasonably describing the nature of the Dispute and the outcome desired by the notifying Party, and (ii) requesting referral to the Steering Committee for good faith negotiations and resolution.

-40-

(b) Following referral of the matter to the Steering Committee, the Parties will cause the Steering Committee to meet as often as the Parties reasonably deem necessary in order to gather and furnish to the other all Information with respect to the Dispute which the Parties believe to be appropriate and germane in connection with the resolution of the Dispute.

(c) During the course of the negotiation, subject to the Parties’ respective confidentiality obligations and subject to the provisions ofArticle VII, all reasonable requests made by either Party to the other for Information will be honored in order that the members of the Steering Committee may be fully advised in the matter. The specific format for the Steering Committee’s discussions and negotiations will be left to the discretion of the Steering Committee but may include the preparation of agreed upon statements of fact or written statements of position furnished to the other Party.

(d) Except as otherwise independently discoverable, nothing said or disclosed, nor any document produced, in the course of any negotiations, conferences or discussions to settle a Dispute pursuant to thisSection 8.2 will be offered or received as evidence or used for impeachment or for any other purpose, but will be considered to have been disclosed for settlement purposes only.

(e) If the Steering Committee does not agree to a resolution of a Dispute within 30 days after the referral of the matter to it, the Parties will seek to resolve such Dispute by mediation administered by AAA and AAA Rules. The Parties will bear equally the costs of the mediation. If the Dispute has not been resolved through mediation within 90 days after the date of service of the Dispute Notice, or such longer period as the Parties may mutually agree in writing (the “Mediation Period”), each Party may refer the dispute to binding arbitration in accordance withSection 8.3.

8.3Arbitration.

(a) If a Dispute is not resolved within the Mediation Period, either Party will have the right to commence arbitration. In that event, the Dispute will be resolved by final and binding arbitration administered by AAA in accordance with AAA Rules. The place of arbitration will be Bloomfield Hills, Michigan. Any Dispute concerning the propriety of the commencement of the arbitration will be finally settled by such arbitration. Judgment on the award rendered by the arbitrators may be entered in any court having jurisdiction thereof or having jurisdiction over the relevant Party or its Assets.

(b) The number of arbitrators will be three. Each Party will appoint one arbitrator. The two Party-appointed arbitrators will agree on a third arbitrator who will chair the arbitral tribunal. Any arbitrator not appointed within a reasonable time will be appointed in accordance with AAA Rules.

-41-

8.4Interim Relief. At any time during the resolution of a Dispute between the Parties, either Party has the right to apply to any court of competent jurisdiction for interim relief, including pre-arbitration attachments or injunctions, necessary to preserve the Parties’ rights or to maintain the Parties’ relative positions until such time as the arbitration award is rendered or the Dispute is otherwise resolved.

8.5Remedies. The arbitrators will have no authority or power to limit, expand, alter, amend, modify, revoke or suspend any condition or provision of this Agreement or any Ancillary Agreement nor any right or power to award punitive, exemplary or treble (or other multiple) damages.

8.6Expenses. Each Party will bear its own costs, expenses and attorneys’ fees in pursuit and resolution of any Dispute;provided,however, that, in the event of any arbitration pursuant toSection 8.3, the non-prevailing Party will bear both Parties’ costs, expenses and attorneys’ fees incurred in connection with such arbitration (including the fees of any arbitrator).

8.7Continuation of Services and Commitments. Unless otherwise agreed in writing, the Parties will, and will cause the members of their respective Groups to, continue to honor all commitments under this Agreement and each Ancillary Agreement to the extent required by such agreements during the course of the dispute resolution pursuant to thisArticle VIII.
