1.MASTER LEASE. By the MASTER LEASE, Owners have leased to SUBLANDLORD the Xxxxxx Facility, as described and depicted on Exhibits A and B to the New Owner Lease. This Sublease is made subject to the MASTER LEASE except where the provisions of the MASTER LEASE are inconsistent with the provisions of this Sublease, in which case the provisions of this Sublease will control. Where in the MASTER LEASE there are duties owed by Owners to SUBLANDLORD which are necessary for the proper enjoyment of this Sublease, SUBLANDLORD will make all commercially reasonable efforts to obtain the performance of such duties by Owners in favor of SUBTENANT, but SUBLANDLORD shall not be liable for the failure of Owners under the terms of MASTER LEASE to perform said duties nor for the result of such failure. If Owners are in default of obligations and SUBLANDLORD is unsuccessful in obtaining Owners’ performance, then upon SUBTENANT’s written request, SUBLANDLORD shall assign to SUBTENANT its rights to enforce such defaulted obligations of the MASTER LEASE against Owners. SUBTENANT hereby agrees to faithfully and promptly perform all of the obligations and duties of

SUBLANDLORD to Owners under the MASTER LEASE with respect only to the Leased Premises, except the obligation of SUBLANDLORD to pay rent, which obligation SUBLANDLORD agrees to continue to perform during the term hereof. Unless SUBLANDLORD is a party and has given written permission: SUBTENANT shall not communicate with any Owner or any other owner of an interest in the Xxxxxx Facility about the MASTER LEASE, this Sublease, the Tolling Agreement, or operations on or utilization of the Xxxxxx Facility or the Blue Stone Mine; and SUBTENANT shall not offer to purchase or lease all or any portion of the Xxxxxx Facility from any Owner or any other owner of an interest in the Xxxxxx Facility without SUBLANDLORD’s prior written consent.

2.LEASED PREMISES. SUBLANDLORD, for and in consideration of the rents, covenants and agreements hereinafter reserved, mentioned and contained on the part of SUBTENANT, its successors and permitted assigns, does hereby lease, rent and demise unto SUBTENANT, and SUBTENANT does hereby take and hire, upon and subject to the conditions and limitations hereinafter expressed, a portion of the Xxxxxx Facility and a portion of the Blue Stone Mine described as follows (the “Leased Premises”):

SUBTENANT shall be solely responsible for determining that the passages and xxxxxxxx to be constructed are complete and ready for SUBTENANT’s entry and use. SUBTENANT shall be solely responsible to inspect (at prudent intervals) and determine, in its sole judgment, that the passages and xxxxxxxx, both existing and hereafter constructed, are safe and suitable to enter, occupy and use for the intended purpose. The parties acknowledge that material removed from the Blue Stone Mine will be spoiled on the surface of the Xxxxxx Facility outside the Leased Premises, and may not be removed.

The term “Sublease Year” means the period commencing on the Commencement Date and ending at 11:59 prevailing eastern time on the day

preceding the first anniversary of the Commencement Date, and each one year period thereafter during the term of this Sublease.

6.RENT.

6.1From the Effective Date until September 30, 2024, SUBTENANT shall pay SUBLANDLORD under the Sublease dated December 16, 2000. From and after October 1, 2024, to the expiration or earlier termination of this Sublease, SUBTENANT shall pay monthly, in advance, the following sums: for the first Sublease Year, the yearly rental shall be THREE HUNDRED THIRTY FIVE THOUSAND DOLLARS ($335,000.00) to be paid in twelve equal monthly installments commencing on the Commencement Date and continuing thereafter as provided herein. This rental rate is referred to as the “Annual Rent” and is subject to increase for each subsequent Sublease Year as provided herein. As used in this Section:

(a)“Index” shall mean the “Consumer Price Index for Urban Wage Earners and Clerical Workers” “(1967=100)” specified for “All Items”, relating to PA-NJ-DE-MD and issued by the Bureau of Labor Statistics of the United States Department of Labor. In the event the Index shall hereafter be converted to a different standard reference base or otherwise revised, the determination of the Percentage Increase (defined below) shall be made with the use of such conversion factor, formula or table for converting the Index as may be published by the Bureau of Labor Statistics or, if said Bureau shall not publish the same, then with the use of such conversion factor, formula or table as may be published by Prentice Hall, Inc., or, failing such publication, by any other nationally recognized publisher of similar statistical information. In the event the Index shall cease to be published, then there shall be substituted for the Index such other index as SUBLANDLORD and SUBTENANT shall agree upon, and, if they are unable to agree within ninety (90) days after the Index ceases to be

published, such matter shall be determined in Philadelphia, Pennsylvania by arbitration in accordance with the Rules of the American Arbitration Association.

(b)“New Index” shall mean the Index reported for the November immediately preceding each Anniversary Date.

(c)“Current Index” shall mean the index derived for the November of the year immediately preceding the year in which a New Index is derived.

(d)“Anniversary Date” shall mean each anniversary of the Commencement Date during the term of this Sublease.

(e)“Percentage Increase” shall mean the percentage equal to the fraction, the numerator of which shall be the New Index less the Current Index, and the denominator of which shall be the Current Index.

The Annual Rent shall be increased on each Anniversary Date by the Percentage Increase, if any, as provided above. It is the intention of the parties that increases in the Annual Rent shall be determined based upon applying the Percentage Increase to the Annual Rent as adjusted in this Section 6.1.

6.2All other sums, charges or amounts which SUBTENANT has agreed to pay to SUBLANDLORD pursuant to this Sublease shall be hereinafter referred to as “Additional Rent,” and shall be collectible as rent. The Annual Rent and Additional Rent shall be payable by wire transfer to SUBLANDLORD in accordance with such wiring instructions as SUBLANDLORD shall from time to time give SUBTENANT written notice. In the event that the New Index is not available by the Anniversary Date, SUBTENANT shall pay the Annual Rent at the then current rate until such New Index is available, and shall, with the next scheduled

payment thereafter, pay all amounts that would have otherwise been due had the New Index been available.

7.USE.

(a)The Leased Premises shall be used only for (i) the operation of the Explosion Business, including the explosion bonding of clad metals, and (ii) performance of services pursuant to the Tolling Agreement (together, the “Permitted Use”). SUBTENANT shall not use or occupy the Leased Premises, or permit the same to be used or occupied, for any purpose other than the Permitted Use. In particular, SUBTENANT shall have no rights to mine or extract minerals from any portion of the Leased Premises. Only the Explosion Areas may be used for explosions.

(b)In the event SUBTENANT’s operations within the limestone mine situated on the Leased Premises result in necessary removal of rocks from the Blue Stone Mine, SUBTENANT shall pile said rocks so removed in a nearby place to be designated by SUBLANDLORD for disposal by Owners. SUBTENANT shall have no right to the rock thus removed nor to the proceeds therefrom. Owners and SUBLANDLORD shall have the right of egress and ingress in order to remove such rocks at their own risk.

(c)SUBTENANT acknowledges that the Blue Stone Mine can become damaged by overuse or improper use, in which case the Blue Stone Mine may be required to be closed or the frequency of explosions performed in the Blue Stone Mine may be required to be limited. As used in this Sublease, “Explosive” means the ammonium nitrate or emulsion explosive material produced by SUBTENANT or such other materials that are approved by SUBLANDLORD from time to time in accordance with the operating procedures used by SUBTENANT, as amended from time to time by SUBTENANT in consultation with

and approval from SUBLANDLORD which approval shall not be unreasonably withheld (the “Procedures”). SUBTENANT shall not manufacture, test, use, or destroy any chemical or explosive materials on the Leased Premises, other than the Explosive identified in the Procedures, without the express written consent of SUBLANDLORD, which consent shall not be unreasonably withheld. SUBTENANT shall not use an explosive load in excess of 16,000 pounds per day without the express written consent of SUBLANDLORD, which consent shall not be unreasonably withheld. SUBTENANT agrees to use and maintain the Blue Stone Mine in such a condition that maintains and maximally prolongs its integrity and useful life, provided, however, that SUBTENANT shall have no responsibility to SUBLANDLORD for adverse effects to the integrity or useful life of the Blue Stone Mine caused by (i) SUBTENANT’s use of Explosives as specified in this paragraph, or (ii) SUBTENANT’s operations according to the Procedures.

(d)SUBTENANT acknowledges that hazards may be involved in conducting explosions in the Blue Stone Mine, including providing the services under the Tolling Agreement. Accordingly, SUBTENANT agrees to perform all work at the Leased Premises in a careful and workmanlike manner and to take all reasonably necessary precautions

in the processing, handling, transportation, and disposal of Explosives, to avoid damage to property or pollution and in compliance with all applicable laws, rules and regulations. In that regard, SUBTENANT shall provide security precautions reasonably required by SUBLANDLORD or Owners to safely process, handle, transport, and dispose of the Explosives.

(e)SUBLANDLORD shall have the right to immediately require the suspension of the explosions on the Leased Premises upon written notice to SUBTENANT, without liability on the part of SUBLANDLORD to SUBTENANT, if at any time SUBLANDLORD in its reasonable judgment determines that SUBTENANT has materially violated any material provision of this Section 7. The right to conduct explosions shall remain suspended until SUBTENANT corrects such violation; provided that SUBTENANT shall have a right of access to the Leased Premises to correct such violations. If SUBTENANT fails to correct any such violation within the time periods set forth in Section 13(a)(iii), an Event of Default shall exist.

8.TAXES AND ASSESSMENTS.

(a)During the term of this Sublease, SUBTENANT shall pay to SUBLANDLORD, as Additional Rent, all real estate taxes and assessments payable by SUBLANDLORD under the MASTER LEASE. Such payment shall be made within 30 days of SUBLANDLORD’s invoice.

SUBTENANT agrees that, at its sole cost and expense, it shall keep and maintain the surface area of the Leased Premises (located adjacent to the entrance of the Blue Stone Mine), including all improvements constructed thereon by SUBTENANT, in good repair, replacement, and appearance during the term of this Sublease. SUBTENANT further agrees that, at its sole cost and expense, it shall with reasonable promptness make all structural and nonstructural, foreseen and unforeseen, and ordinary and extraordinary changes and repairs of every kind and nature which may be required to be made upon or in connection with Leased Premises or any part thereof, surface or subsurface, exterior and interior, in order to keep and maintain Leased Premises in such good repair, replacement and appearance, so that the Leased Premises are in substantially the same condition at the end of the term of this Sublease as they were at the commencement of the Dupont Sublease, subject to normal wear and tear. Except as may be required pursuant to Sections 5 and 12 herein, SUBLANDLORD shall not be required to maintain, repair, or rebuild, or to make any alterations, replacements, or renewals of any nature or description to Leased Premises or any part thereof, whether ordinary or extraordinary, structural or nonstructural, foreseen or unforeseen, or to maintain Leased Premises or any part thereof in any way, and except as may be required pursuant to Section 5 or 12 herein, SUBTENANT hereby expressly waives any right to make repairs or replacements at the expense of SUBLANDLORD which may be provided for in any statute or law in effect at the time of the execution of this Sublease or any statute or law which may thereafter be enacted.

The parties acknowledge that the MASTER LEASE has not been signed by all Owners of the Xxxxxx Facility. SUBLANDLORD has no reason to believe that any of such Owners will disturb SUBTENANT’s use or adversely affect SUBTENANT’s peaceful, quiet enjoyment and possession of the Leased Premises.

(iii)If SUBTENANT defaults in the observance or performance of any provision of this Sublease (other than those provisions referenced hereinabove under subparagraph (a)(i) and (ii)), or fails to take the action required by Section 7, and such default continues for a period of thirty (30) days after SUBLANDLORD shall have given notice to SUBTENANT specifying such default; provided, however, if such default cannot be wholly cured within such thirty (30) day period, then SUBTENANT shall not be deemed to be in default so long as SUBTENANT has commenced the cure of such default within said thirty (30) day period and continues, with due diligence, to prosecute said cure;

(b)If an Event of Default shall occur, the following provisions shall apply and SUBLANDLORD shall have, in addition to all other rights and remedies available at law or in equity, the rights and remedies set forth therein, which rights and remedies may be exercised upon or at any time following the occurrence of an Event of Default unless, prior to such exercise, SUBLANDLORD shall agree in writing with SUBTENANT that the Event(s) of Default has been cured by SUBTENANT in all respects.

(i)Acceleration of Rent. By notice to SUBTENANT, SUBLANDLORD shall have the right to accelerate all Annual Rent and any other amount due hereunder and otherwise payable in installments over the remainder of the Term, and, at

SUBLANDLORD’s option, any other Additional Rent to the extent that such Additional Rent can be determined and calculated to a fixed sum; and the amount of accelerated rent to the termination date, without further notice or demand for payment, shall be due and payable by SUBTENANT within five (5) days after SUBLANDLORD has so notified SUBTENANT, such amount collected from SUBTENANT shall be discounted to present value using an interest rate of six percent (6%) per annum. Additional Rent which has not been included, in whole or in part, in accelerated rent, shall be due and payable by SUBTENANT during the remainder of the Term, in the amounts and at the times otherwise provided for in this Sublease.

Notwithstanding the foregoing or the application of any rule of law based on election of remedies or otherwise, if SUBTENANT fails to pay the accelerated rent in full when due, SUBLANDLORD thereafter shall have the right by notice to SUBTENANT, (i) to terminate SUBTENANT’s further right to possession of the Leased Premises and (ii) to terminate this Sublease under subparagraph (b) below; and if SUBTENANT shall have paid part but not all of the accelerated rent, the portion thereof attributable to the period equivalent to the part of the Term remaining after SUBLANDLORD’s termination of possession or termination of this Sublease shall be applied by SUBLANDLORD against SUBTENANT’s obligations owing to SUBLANDLORD, as determined by the applicable provisions of subparagraphs (c) and (d) below.

(ii)Termination of Sublease. By notice to SUBTENANT, SUBLANDLORD shall have the right to terminate this Sublease as of a date specified in the notice of termination and in such case, SUBTENANT’s rights, including any based on any option to renew, to the possession and use of the Leased Premises shall end absolutely as of the termination date; and this Sublease shall also terminate in all respects except for the provisions

hereof regarding SUBLANDLORD’s damages and SUBTENANT’s liabilities arising prior to, out of and following the Event of Default and the ensuing termination.

Following such termination and the notice of same provided above (as well as upon any other termination of this Sublease by expiration of the Term or otherwise) SUBLANDLORD immediately shall have the right to recover possession of the Leased Premises; and to that end, SUBLANDLORD may enter the Leased Premises and take possession, without the necessity of giving SUBTENANT any notice to quit or any other further notice, with or without legal process or proceedings, and in so doing SUBLANDLORD may remove SUBTENANT’s property (including any improvements or additions to the Leased Premises which SUBTENANT made, unless made with SUBLANDLORD’s consent which expressly permitted SUBTENANT to not remove the same upon expiration of the Term), as well as the property of others as may be in the Leased Premises, and make disposition thereof in such manner as SUBLANDLORD may deem to be commercially reasonable and necessary under the circumstances.

(c)Subtenant’s Continuing Obligations/Sublandlord’s Reletting Rights.

(i)Unless and until SUBLANDLORD shall have terminated this Sublease under subparagraph (b) above, SUBTENANT shall remain fully liable and responsible to perform all of the covenants and to observe all the conditions of this Sublease throughout the remainder of the Term to the early termination date; and, in addition, SUBTENANT shall pay to SUBLANDLORD, upon demand and as Additional Rent, the total sum of all damages in (d) below, as SUBLANDLORD incurs, because of any Event of Default having occurred.

(ii)If SUBLANDLORD either terminates SUBTENANT’s right to possession without terminating this Sublease or terminates this Sublease and SUBTENANT’s leasehold estate as above provided, then, subject to the provisions below, SUBLANDLORD shall have the unrestricted right to relet the Leased Premises or any part(s) thereof to such tenant(s) on such provisions and for such period(s) as SUBLANDLORD may deem appropriate. If SUBLANDLORD relets the Leased Premises after such a default, the costs recovered from SUBTENANT shall be reallocated to take into consideration any additional rent which SUBLANDLORD receives from the new tenant which is in excess to that which was owed by SUBTENANT.

(d)Sublandlord’s Damages.

(i)Upon the occurrence of an Event of Default, the damages which SUBLANDLORD shall be entitled to recover from SUBTENANT shall be the sum of:

(A)all Annual Rent and Additional Rent accrued and unpaid as of the termination date; and

(B)(1) all costs and expenses incurred by SUBLANDLORD in recovering possession of the Leased Premises, including removal and storage of SUBTENANT’s property, (2) the costs and expenses of restoring the Leased Premises to the condition in which the same were to have been surrendered by SUBTENANT as of the expiration of the Term, and (3) the costs of reletting commissions; and

(C)all Annual Rent and Additional Rent (to the extent that the amount(s) of Additional Rent has been then determined) otherwise payable by SUBTENANT over the remainder of the Term as reduced to present value. Less deducting from the total determined under subparagraphs (A), (B) and (C) all Annual Rent and all other

Additional Rent to the extent determinable as aforesaid, (to the extent that like charges would have been payable by SUBTENANT) which SUBLANDLORD receives from other tenant(s) by reason of the leasing of the Leased Premises or part during or attributable to any period falling within the otherwise remainder of the Term.

(ii)The damage sums payable by SUBTENANT under the preceding provisions of this paragraph (d) shall be payable on demand from time to time as the amounts are determined; and if from SUBLANDLORD’s subsequent receipt of rent as aforesaid from reletting, there be any excess payment(s) by SUBTENANT by reason of the crediting of such rent thereafter received, the excess payment(s) shall be refunded by SUBLANDLORD to SUBTENANT, without interest.

(iii)SUBLANDLORD may enforce and protect the rights of SUBLANDLORD hereunder by a suit or suits in equity or at law for the specific performance of any covenant or agreement contained herein, and for the enforcement of any other appropriate legal or equitable remedy, including, without limitation, injunctive relief, and for recovery of all moneys due or to become due from SUBTENANT under any of the provisions of this Sublease.

(e)Sublandlord’s Right to Cure. Without limiting the generality of the foregoing, if SUBTENANT shall be in default in the performance of any of its obligations hereunder, SUBLANDLORD, without being required to give SUBTENANT any notice or opportunity to cure, may (but shall not be obligated to do so), in addition to any other rights it may have in law or in equity, cure such default on behalf of SUBTENANT, and SUBTENANT shall reimburse SUBLANDLORD upon demand for any sums paid or costs incurred by SUBLANDLORD in curing such default, including reasonable attorneys’ fees and other legal

expenses, together with interest at 10% per annum Rate from the dates of SUBLANDLORD’s incurring of costs or expenses.

SUBTENANT further waives the right to any notices to quit as may be specified in the SUBLANDLORD and SUBTENANT Act of Pennsylvania, Act of April 6, 1951, as amended, or any similar or successor provision of law, and agrees that five (5) days’ notice shall be sufficient in any case where a longer period may be statutorily specified.

(i)Additional Remedies. In addition to, and not in lieu of any of the foregoing rights granted to SUBLANDLORD: WHEN THIS SUBLEASE OR TENANT’S RIGHT OF POSSESSION SHALL BE TERMINATED BY COVENANT OR CONDITION BROKEN, OR FOR ANY OTHER REASON, EITHER DURING THE TERM OF THIS SUBLEASE OR ANY RENEWAL OR EXTENSION THEREOF, AND ALSO WHEN AND AS SOON AS THE TERM HEREBY CREATED OR ANY EXTENSION THEREOF SHALL HAVE EXPIRED, IT SHALL BE LAWFUL FOR ANY ATTORNEY AS ATTORNEY FOR TENANT TO FILE AN AGREEMENT FOR ENTERING IN ANY COMPETENT COURT AN ACTION TO CONFESS JUDGMENT IN EJECTMENT AGAINST TENANT AND ALL PERSONS CLAIMING UNDER SUBTENANT, WHEREUPON, IF SUBLANDLORD SO DESIRES, A WRIT OF EXECUTION OR OF POSSESSION MAY ISSUE FORTHWITH, WITHOUT ANY PRIOR WRIT OF PROCEEDINGS, WHATSOEVER, AND PROVIDED THAT IF FOR ANY REASON AFTER SUCH ACTION SHALL HAVE BEEN COMMENCED THE SAME SHALL BE DETERMINED AND THE POSSESSION OF THE PREMISES HEREBY DEMISED REMAIN IN OR BE RESTORED TO SUBTENANT, SUBLANDLORD SHALL HAVE THE RIGHT UPON ANY SUBSEQUENT DEFAULT

OR DEFAULTS, OR UPON THE TERMINATION OF THIS SUBLEASE AS HEREINBEFORE SET FORTH, TO BRING ONE OR MORE ACTION OR ACTIONS AS HEREINBEFORE SET FORTH TO RECOVER POSSESSION OF THE SAID PREMISES.

In any action to confess judgment in ejectment, SUBLANDLORD shall first cause to be filed in such action an affidavit made by it or someone acting for it setting forth the facts necessary to authorize the entry of judgment, of which facts such affidavit shall be conclusive evidence, and if a true copy of this Sublease (and of the truth of the copy such affidavit shall be sufficient evidence) be filed in such action, it shall not be necessary to file the original as a warrant of attorney, any rule of Court, custom or practice to the contrary notwithstanding.

(INITIAL). SUBTENANT WAIVER. SUBTENANT SPECIFICALLY ACKNOWLEDGES THAT SUBTENANT HAS VOLUNTARILY, KNOWINGLY AND INTELLIGENTLY WAIVED CERTAIN DUE PROCESS RIGHTS TO A PREJUDGMENT HEARING BY AGREEING TO THE TERMS OF THE FOREGOING PARAGRAPHS REGARDING CONFESSION OF JUDGMENT IN EJECTION. SUBTENANT FURTHER SPECIFICALLY AGREES THAT IN THE EVENT OF DEFAULT, SUBLANDLORD MAY PURSUE MULTIPLE REMEDIES INCLUDING OBTAINING POSSESSION PURSUANT TO A JUDGMENT BY CONFESSION OF EJECTION AND ALSO OBTAINING A MONEY JUDGMENT FOR PAST DUE AND ACCELERATED AMOUNTS AND EXECUTING UPON SUCH JUDGMENT. SUBTENANT SPECIFICALLY WAIVES ANY CLAIM AGAINST SUBLANDLORD AND SUBLANDLORD’S COUNSEL FOR VIOLATION OF SUBTENANT’S

CONSTITUTIONAL RIGHTS IN THE EVENT THAT EJECTION IS CONFESSED PURSUANT TO THIS SUBLEASE.

(f)Interest on Damage Amounts. Any sums payable by SUBTENANT hereunder, which are not paid after the same shall be due, shall bear interest from that day until paid at the rate of four (4%) percent over the then Prime Rate as published daily under the heading “Money Rates” in The Wall Street Journal, unless such rate be usurious as applied to SUBTENANT, in which case the highest permitted legal rate shall apply (the “Default Rate”).

(g)SUBLANDLORD’s Statutory Rights. SUBLANDLORD shall have all rights and remedies now or hereafter existing at law or in equity with respect to the enforcement of SUBTENANT’s obligations hereunder and the recovery of the Leased Premises. No right or remedy herein conferred upon or reserved to SUBLANDLORD shall be exclusive of any other right or remedy, but shall be cumulative and in addition to all other rights and remedies given hereunder or now or hereafter existing at law. SUBLANDLORD shall be entitled to injunctive relief in case of the violation, or attempted or threatened violation, of any covenant, agreement, condition or provision of this Sublease, or to a decree compelling performance of any covenant, agreement, condition or provision of this Sublease.

(h)Remedies Not Limited. Nothing herein contained shall limit or prejudice the right of SUBLANDLORD to exercise any or all rights and remedies available to SUBLANDLORD by reason of default or to prove for and obtain in proceedings under any bankruptcy or insolvency laws, an amount equal to the maximum allowed by any law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether

or not the amount be greater, equal to, or less than the amount of the loss or damage referred to above.

(i)No Waiver by SUBLANDLORD. No delay or forbearance by SUBLANDLORD in exercising any right or remedy hereunder, or SUBLANDLORD’s undertaking or performing any act or matter which is not expressly required to be undertaken by SUBLANDLORD shall be construed, respectively, to be a waiver of SUBLANDLORD’s rights or to represent any agreement by SUBLANDLORD to undertake or perform such act or matter thereafter. Waiver by SUBLANDLORD of any breach by SUBTENANT of any covenant or condition herein contained (which waiver shall be effective only if so expressed in writing by SUBLANDLORD) or failure by SUBLANDLORD to exercise any right or remedy in respect of any such breach shall not constitute a waiver or relinquishment for the future of SUBLANDLORD’s right to have any such covenant or condition duly performed or observed by SUBTENANT, or of SUBLANDLORD’s rights arising because of any subsequent breach of any such covenant or condition nor bar any right or remedy of SUBLANDLORD in respect of such breach or any subsequent breach. SUBLANDLORD’s receipt and acceptance of any payment from SUBTENANT which is tendered not in conformity with the provisions of this Sublease or following an Event of Default (regardless of any endorsement or notation on any check or any statement in any letter accompanying any payment) shall not operate as an accord and satisfaction or a waiver of the right of SUBLANDLORD to recover any payments then owing by SUBTENANT which are not paid in full, or act as a bar to the termination of this Sublease and the recovery of the Leased Premises because of SUBTENANT’s previous default.

14.INSURANCE.

(a)SUBTENANT shall at its expense obtain and maintain, or cause to be obtained and maintained, insurance during the term of this Sublease. Comprehensive or Commercial General Liability Insurance with bodily injury and property damage combined single limits of at least Ten Million Dollars ($10,000,000) per occurrence, with a deductible of not more than One Hundred Thousand Dollars ($100,000). Such insurance shall include, but not necessarily be limited to, specific coverage for contractual liability encompassing the indemnification provisions in Paragraph 12, broad form property damage liability, personal injury liability, explosion and collapse hazard coverage, and products/completed operations liability.

(b)The amounts of insurance required in this Paragraph 14 may be satisfied by SUBTENANT purchasing primary coverage in the amounts specified or by buying a separate excess Umbrella Liability policy together with lower limit primary underlying coverage. The structure of the coverage is SUBTENANT’s option, so long as the total amount of insurance meets the requirements of this Paragraph 14. The coverages described above and any Umbrella or Excess coverage should be “occurrence” form policies. The insurance requirements listed above are minimum requirements. SUBLANDLORD and SUBTENANT shall annually renegotiate these minimum insurance requirements to reflect increases in insured values where applicable. Further, neither failure to comply nor full compliance by either party with the insurance provisions of this Agreement shall limit or relieve SUBTENANT OR SUBLANDLORD from indemnifying and holding harmless SUBLANDLORD OR SUBTENANT, as the case may be, in compliance with the provisions of this Agreement.

(c)SUBLANDLORD shall at its expense obtain and maintain, or cause to be obtained and maintained, insurance covering its interests during the term of this Sublease.

(d)Upon SUBLANDLORD’s request, certificates of insurance evidencing the coverages required above of SUBTENANT shall be filed with SUBLANDLORD. Such certificates shall provide that the insurer will give SUBLANDLORD thirty (30) days advance notice of any changes in or cancellation of coverage. SUBTENANT shall name SUBLANDLORD as an additional insured under all policies of insurance relating to the Leased Premises

Neither failure of SUBTENANT or SUBLANDLORD to comply with any or all of the insurance provisions of the Agreement, nor the failure to secure endorsements on the policies as may be necessary to carry out the terms and provisions of the Agreement, shall be construed to limit or relieve SUBTENANT or SUBLANDLORD from any of its obligations under the Agreement, including the Insurance Article.

15.WAIVER OF SUBROGATION. Each party hereto, and anyone claiming through or under them by way of subrogation, waives and releases any cause of action it might have against the other party and their respective employees, officers, members, shareholders, partners, trustees and agents, on account of any loss or damage that is insured against under any insurance policy required to be obtained hereunder (to the extent that such loss or damage is recoverable under such insurance policy) that covers the Leased Premises, SUBLANDLORD’s or SUBTENANT’s fixtures, personal property, leasehold improvements or business and which names SUBLANDLORD or SUBTENANT, as the case may be, as a party insured. Each party hereto agrees that it will cause its insurance carrier to endorse all applicable policies waiving the

xxxxxxx’s right of recovery under subrogation or otherwise against the other party. During any period while such waiver of right of recovery is in effect, each party shall look solely to the proceeds of such policies for compensation for loss, to the extent such proceeds are paid under such policies.

16.CASUALTY. If, during the term of this Sublease, the Leased Premises, including the Blue Stone Mine, shall become unfit or unsafe for the operation of the Explosion Business or operations under the Tolling Agreement (a “Casualty”), then all investments and all operation of the Explosion Business and operations under the Tolling Agreement shall be suspended, and as soon as commercially reasonably practicable:

16.1If the Casualty is caused by any cause within SUBTENANT’s reasonable control (other than operation of the Explosion Business or operations under the Tolling Agreement), then (a) SUBTENANT shall eliminate the Casualty at its sole expense under Section 9, (b) rent shall not be suspended, and (c) the Tolling Agreement shall not terminate and performance under the Tolling Agreement shall not be suspended.

16.2If the Casualty is caused by the elements, Act of God or other cause outside SUBTENANT’s reasonable control (other than operation of the Explosion Business or operations under the Tolling Agreement), then (a) both parties shall cooperate, each acting commercially reasonably, to eliminate the Casualty and resume investments and operations, (b) rent shall be suspended if repairs take more than 30 days, and (c) the Tolling Agreement shall not terminate but performance of the parties’ obligations under the Tolling Agreement may be suspended under the terms of subsection 5(c) of the Tolling Agreement.

16.3If the Casualty is caused by operation of the Explosion Business or operations under the Tolling Agreement, or by both operations, then the parties shall jointly

engage Earthtech, Inc., or another a reputable professional engineering firm with substantially similar qualifications, to determine the percentage of the Casualty caused by each of the Explosion Business and the operations under the Tolling Agreement, to devise a plan for eliminating the Casualty (which may include expansion of the Blue Stone Mine by the creation of new passages or xxxxxxxx), and to determine when each area is safe to use. Upon receipt of the engineering firm’s report of the respective percentages and the Casualty elimination plan: (a) the parties shall implement the Casualty elimination plan, each acting commercially reasonably, and each party shall bear the expense of the implementation in accordance with its respective percentage as determined by the engineering firm, (b) if 75% or more of the Casualty is caused by operations under the Tolling Agreement, rent shall be suspended from the date of the Casualty until the Blue Stone Mine may be used safely for operation of the Explosion Business, and (c) the Tolling Agreement shall not terminate but performance of the parties’ obligations under the Tolling Agreement may be suspended under the terms of subsection 5(c) of the Tolling Agreement. If the Casualty elimination plan requires expansion of the Blue Stone Mine, then the new passages shall be used solely for the Explosion Business (and for access to the xxxxxxxx) and the new xxxxxxxx shall be used solely for operations under the Tolling Agreement.

16.4If the Casualty is eliminated under subsection 16.2 or 16.3 such that operation of the Explosion Business can resume, but operations under the Tolling Agreement cannot resume but are expected to resume within 90 days after the resumption of operation of the Explosion Business, then: (a) rent shall resume (if suspended), and (b) the Tolling Agreement shall not terminate but performance of the parties’ obligations under the Tolling Agreement may be suspended under the terms of subsection 5(c) of the Tolling Agreement. If the Casualty is eliminated under subsection 16.2 or 16.3 such that operations

under the Tolling Agreement can resume, but operations of the Explosion Business cannot resume but are expected to resume within 90 days after the resumption of operations under the Tolling Agreement, then: (a) rent shall resume (if suspended), and (b) performance under the Tolling Agreement shall resume.

16.5If the Casualty is eliminated under subsection 16.2 or 16.3 such that operation of the Explosion Business can resume, but operations under the Tolling Agreement cannot resume within 90 days after resumption of the Explosion Business, then: (a) this Sublease shall continue and rent shall be paid, and (b) the parties shall attempt to identify and develop an additional, alternative or substitute site or facility in accordance with the provisions of subsection 5(c) of the Tolling Agreement.

16.6If the Casualty is eliminated under subsection 16.2 or 16.3 such that operations under the Tolling Agreement can resume, but operation of the Explosion Business cannot resume within 90 days after resumption of operations under the Tolling Agreement, or if the Casualty cannot be eliminated such that operation of the Explosion Business can resume within 120 days after the date of the Casualty, notwithstanding the efforts of the parties under subsection 16.2 or 16.3, above, then at SUBTENANT’s option, SUBTENANT shall elect one of the following:

(1)SUBTENANT may terminate this Sublease by written notice to SUBLANDLORD (the “Notice of Termination”) provided however the Notice of Termination shall not become effective until six months after the date it was provided (the “Effective Date of Termination”). SUBTENANT shall not be liable to pay any rent after the Notice of Termination is submitted; provided however the term of the Sublease and the other

provisions contained therein shall be extended automatically if necessary through the Effective Date of Termination, and the Tolling Agreement shall also continue through the Effective Date of Termination. Upon the Effective Date of Termination, the Sublease and Tolling Agreement shall automatically terminate, and the Non-Extension Payment, if applicable, shall be made by SUBTENANT in accordance with the provisions set forth in Exhibit E

(2) SUBTENANT may restore the Leased Premises by notifying SUBLANDLORD as soon as reasonably possible (but in no event more than ninety (90) days after the Casualty) that the SUBTENANT is diligently pursuing plans for restoration of the Leased Premises. If SUBTENANT does not notify SUBLANDLORD of its election within the time hereinabove specified, then SUBTENANT shall be deemed to have notified SUBLANDLORD of its election to restore the Leased Premises on the ninetieth day after the Casualty. If SUBTENANT elects to restore the Leased Premises, then within ninety (90) working days from the delivery of notice of such election SUBTENANT shall either restore the Leased Premises, or, if such restoration cannot be completed in ninety (90) working days, commence and diligently pursue such restoration. In case of the election by SUBTENANT in this subparagraph (2) to restore the Leased Premises, rent shall resume (if suspended) when operation of the Explosion Business can resume, and the Tolling Agreement shall not terminate.

17.QUIET ENJOYMENT. SUBLANDLORD covenants and warrants that, as long as no Event of Default shall have occurred and be continuing under this Sublease, SUBLANDLORD or persons claiming by, through or under SUBLANDLORD will take no action or neglect to take any action which interferes with the peaceful and quiet enjoyment and possession of the Leased Premises by SUBTENANT for the term hereof and any extensions to the term.

18.ASSIGNMENT AND SUBLETTING.

(a)SUBTENANT shall have the right to assign its rights and duties under this Sublease, either as collateral security or to an affiliate of SUBTENANT created in connection with the financing arrangements entered into by SUBTENANT or otherwise, by notifying SUBLANDLORD of such assignment. In the event of any such assignment, SUBTENANT shall continue to remain primarily liable for performance hereunder for the term of this Sublease, including any renewals. “Affiliate” means an entity controlled by or under the control of SUBTENANT or SUBTENANT’s parent DMC Global Inc. “Control” or “Controlled” means ownership of more than 50% of the ownership interests of such entity or the ability to elect a majority of the board or other governing body of such entity.

(b)Except as provided in this Sublease, neither party may assign this Sublease in whole or in part, or any rights granted hereunder, without the prior written consent of the other party, which consent shall not be unreasonably withheld, delayed or conditioned so long as no Event of Default shall have occurred and then be continuing. Except as provided in this Sublease, any transfer, assignment, delegation or attempted transfer, assignment or delegation under this Sublease or of any of such rights or duties herein granted or imposed whether voluntary, by operation of law or otherwise, without consent in writing, shall cause this

Sublease to be terminated at the election of the party whose written consent has not been obtained. SUBTENANT shall not, without the prior written consent of SUBLANDLORD, sublet any portion of the Leased Premises. Subject to the foregoing, this Sublease shall be binding upon and shall inure to the benefit of the parties and their successors and assigns.

Notwithstanding anything to the contrary contained herein, either party may assign this Sublease to the purchaser of all or substantially all of such party’s assets.

19.GOVERNING LAW. This Sublease and the performance thereof shall be governed, interpreted, construed and regulated by the laws of the Commonwealth of Pennsylvania.

20.CONSENT TO JURISDICTION. SUBTENANT hereby consents to the exclusive jurisdiction of the state and federal courts located in any county in the Commonwealth of Pennsylvania to resolve any dispute arising under this Sublease or in connection with SUBTENANT’s use, occupancy or enjoyment of the Leased Premises.

21.SURRENDER. SUBTENANT xxxxxx agrees to surrender the Leased Premises in good condition and repair, normal wear and tear excepted. Notwithstanding anything herein to the contrary (except if required by law), SUBTENANT shall be required to have performed a Phase 1 environmental audit upon the termination or expiration of this Sublease at its sole expense. SUBTENANT shall have no right to hold over beyond the expiration of the Term and in the event SUBTENANT shall fail to deliver possession of the Leased Premises as herein provided, such occupancy shall not be construed to effect or constitute other than a tenancy at sufferance. During any period of occupancy beyond the expiration of the Term the amount of rent owed to SUBLANDLORD by SUBTENANT shall automatically become one hundred fifty percent (150%) the Annual Rent as those sums are at that time calculated under the

provisions of the Sublease. If SUBTENANT fails to surrender the space within thirty (30) days of the termination date, SUBLANDLORD may elect to automatically extend the Term for an additional month or additional year, at SUBLANDLORD’s option, with an Annual Rent of one hundred and fifty percent (150%) the sum of the Annual Rent as those sums are at that time calculated under the provisions of the Sublease. The acceptance of rent by SUBLANDLORD or the failure or delay of SUBLANDLORD in notifying or evicting SUBTENANT following the expiration or sooner termination of the Term shall not create any tenancy rights in SUBTENANT and any such payments by SUBTENANT may be applied by SUBLANDLORD against its costs and expenses, including attorney’s fees incurred by SUBLANDLORD as a result of such holdover. The provisions of this Paragraph shall survive the expiration or sooner termination of this Sublease.

22.AMENDMENT AND RECORDATION. This Sublease may not be amended, supplemented, or modified, except by an instrument in writing, signed by SUBLANDLORD and SUBTENANT. This Sublease may not be recorded by either party provided that either party may record a memorandum of lease of this Sublease.

23.WAIVER. Failure of SUBLANDLORD or SUBTENANT to complain of any act or omission on the part of the other party, no matter how long the same may continue, shall not be deemed to be a waiver by said party of any of its rights hereunder. No waiver by SUBLANDLORD or SUBTENANT at any time, express or implied, of any breach of any provision of this Sublease shall be deemed a waiver of a breach of any other provision of this Sublease or a consent to any subsequent breach of the same or any other provision.

24.BROKER. Each party hereby represents and warrants to the other party that it has not dealt with any real estate broker or finder in connection with the transaction

evidenced by this Sublease, and said party agrees to indemnify, defend and hold harmless the other party from and against any threatened or asserted claims, liabilities, losses or judgments (including reasonable attorneys’ fees and disbursements) by any such broker or finder claiming to have dealt with the indemnifying party. This provision shall survive the termination or expiration of this Sublease.
