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

carrier’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 be destroyed, or so injured or damaged by fire, the elements, acts of God, or other insurable casualty, structural defects or from any other cause so as to be unfit for occupancy and not be economically feasible for the operation of the Explosion Business, this Sublease shall, at SUBTENANT’s option, terminate and SUBTENANT shall not be liable to pay rent after such occurrence. If the injury or damage is such that SUBTENANT notifies SUBLANDLORD as soon as reasonably possible (but in no event more than ninety (90) days after such injury) that the SUBTENANT is diligently pursuing plans for restoration of the Leased Premises and within ninety (90) working days from the delivery of such notice, either restores the Leased Premises, or, if such restoration cannot be completed in ninety (90) working days, commences and diligently pursues such restoration, this Sublease shall not be terminated but the rent shall be suspended as to that portion of the Leased Premises rendered untenantable or unsuitable for the operation of SUBTENANT’s business and in such case any rent paid in advance but unearned shall be refunded to SUBTENANT. If SUBTENANT does not notify SUBLANDLORD within the time hereinabove specified or if as soon as possible (but in no event longer than ninety (90) working days after the date of the injury), SUBTENANT (a) is not diligently pursuing the necessary repairs, or (b) the Parties agree that the repairs cannot be completed within one hundred eighty (180) days following the date of such notice, then this

Sublease may immediately be terminated by SUBLANDLORD and neither party shall have any further obligations hereunder, except those specifically intended to survive termination.

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, SNPE, 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 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, SUBLANDLORD may assign this Sublease to the purchaser of all or substantially all of SUBLANDLORD’s Business.

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 hereby 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.

25. NOTICES. Every notice, approval, consent or other communication required or permitted under this Sublease shall be in writing, shall be deemed to have been duly given three days after mailing by US Mail and or next day if by nationally known overnight carrier for priority next day delivery, and shall be valid only if either served personally on the party to whom notice is to be given, or mailed to the party to whom notice is to be given, by first class registered or certified mail, return receipt requested, or by nationally recognized overnight carrier for next day priority delivery, in each case postage prepaid, and addressed to the addressee at the address stated opposite its name below, or at the most recent address specified by written notice given to the other party in the manner provided in this Paragraph.
