"Land" means the soil and water on or beneath the ground surface, Released Hazardous Substances presently in the soil or groundwater or any abandoned object below the ground surface and any building or other permanent structures, whether or not abandoned, on the ground surface. Land does not include objects beneath the ground surface in use or intended for future use at the time of the Closing, including but not limited to, active pipelines, sewers, drains or underground storage tanks except to the extent these objects relate to, or are connected with, the Release of a Hazardous Substance.

"Lowest Cost Response" means the Response to Environmental Conditions that: (i) addresses the Hazardous Substances present in an Area of Environmental Concern at the lowest cost, considered as a whole, as compared to any other Response to Environmental Conditions; and (ii) does not have a material adverse effect on the operation of a Facility. The determination of which Response to Environmental Conditions is the Lowest Cost Response shall be based on the application of the Remediation Standards pertaining to the Hazardous Substances to be addressed by the Response to Environmental Conditions (the "Applicable Remediation Standards") that are: (x) the least stringent Remediation Standards applicable to Land used for purposes for which the HAC Facilities were used at the time of Closing; and (y) in effect at the time the Response to Environmental Conditions is implemented, provided however that if a Material Change in a Remediation Standard has occurred, the Applicable Remediation Standards shall be the Remediation Standards in effect at the time of Closing. For purposes of determining the Lowest Cost Response, the cost of a Response to Environmental Conditions shall specifically include, but not be limited to: (i) costs arising from the necessary cessation of production activities that would directly result from the implementation of such Response to Environmental Conditions; and (ii) the costs of removing and disposing of any building, and any component parts thereof, that would be necessitated by such Response to Environmental Conditions. Taking no action shall constitute the Lowest Cost Response if, after investigation of the Environmental Conditions of the Area of Environmental Concern, taking no action is determined to be consistent with Environmental Laws and Applicable Remediation Standards. If taking no action is not consistent with Environmental Laws and Applicable Remediation Standards, the least costly non-permanent remedy (such as an Institutional Control or an Engineering Control) shall be the Lowest Cost Response, provided that such non-permanent remedy is consistent with Environmental Laws and Applicable Remediation Standards and is less costly than the least costly permanent remedy (such as the excavation and removal of contaminated soil). Approval of a Remedial Action by an Environmental Authority exercising jurisdiction over an Area of Environmental Concern is not evidence that such Remedial Action constitutes the Lowest Cost Response if: (i) a Material Change in a Remediation Standard with respect to any Hazardous Substances to be addressed by the Response to Environmental Conditions has occurred; or (ii) a Response to Environmental Conditions of lower cost reasonably

could have been proposed to such Environmental Authority; provided however, that if: (x) there has not been a Material Change in the Remediation Standards applicable to the Response to Environmental Conditions; (y) a Party has presented and diligently pursued a proposal to the applicable Environmental Authority to implement a Response to Environmental Conditions; and (z) the Environmental Authority exercising jurisdiction over such Area of Environmental Concern has rejected such proposal as inconsistent with Environmental Laws, then such rejection shall create a rebuttable presumption that the proposal was not the Lowest Cost Response.

"Material Change in a Remediation Standard" means an order of magnitude (tenfold) increase in stringency of a Remediation Standard between the numeric value in effect at the time of Closing and the numeric value in effect at the time a Response to Environmental Conditions is implemented, such as, for example, a change in the numeric value of a Remediation Standard from 10 parts per million to 1 part per million. With respect to numeric Remediation Standards that are derived by application of narrative Remediation Standards (such as risk based criteria), a determination that a Material Change in a Remediation Standard has occurred shall be based on the evidence of actual guidances, reports or other documents issued, promulgated or approved by Environmental Authorities, in effect at the time of Closing, setting forth the methodology by which numeric Remediation Standards shall be derived from the narrative Remediation Standards.

"Non-Federal Land" means a HAC Facility, or any portion thereof, which is not owned by the United States.

"Notice of Environmental Condition" means a notice submitted pursuant to Article IX of this Environmental Agreement.

"Off-Site Environmental Conditions" means Environmental Conditions other than Environmental Conditions at HAC Facilities.

"Party" means either Hercules or Alliant. "Parties" shall mean Hercules and Alliant.

"Phase II of the BEA" means a second phase of the BEA to be performed in accordance with Article II that is intended to further characterize Environmental Conditions at one or more HAC Facilities and may include the taking and analysis of soil and groundwater samples at or from such HAC Facilities.

"Principal Agreement" means the Purchase and Sale Agreement between the Parties.

"Recovery" means the amount received by a Party under or pursuant to any judgment, settlement or other resolution of any action against a third party, less any reasonable attorneys' fees, experts' and consultant fees and other expenses incurred by the Party in pursuing such action.

"Release" means any intentional or unintentional release, discharge, spill, leaking, pumping, pouring, emitting, emptying, injection, disposal or dumping into the Environment.

"Remedial Action" means any and all: (i) investigations of Environmental Conditions of any kind or nature whatsoever, including but not limited to, assessments, remedial investigations, sampling or monitoring; or (ii) actions taken to address Environmental Conditions of any kind or nature whatsoever, including but not limited to, the use, implementation, application, installation, operation or maintenance of removal actions, in-situ or ex-situ remediation technologies applied to the surface and sub-surface soils (including but not limited to, biological treatment, land farming, soil vapor extraction, soil washing, solvent extraction and thermal desorption), excavation and off-site treatment or disposal of soils, ▇▇▇▇▇, sumps, trenches or other systems for the recovery of groundwater or free product, systems for long term treatment of surface water or groundwater, Engineering Controls or Institutional Controls.

"Remediation Agreement" means an agreement between a Party and the NJDEP pursuant to the terms of ISRA permitting the consummation of the Transaction.

"Remediation Standards" means either numeric or narrative standards to which Hazardous Substances in, on or around Land must be remediated as established pursuant to Environmental Laws by an Environmental Authority with jurisdiction over such Land.

"Response to Environmental Conditions" means any response, including but not limited to, any Remedial Action, or no action, to address the Hazardous Substances present in an Area of Environmental Concern that, if implemented at such Area of Environmental Concern, would satisfy the least stringent Remediation Standards or Environmental Laws applicable to Land used for purposes for which the HAC Facilities were used at the time of Closing or as required by any lease agreement pertaining to a HAC Facility in effect at the time of Closing, whichever is more stringent.

"Third-Party Claim" means an Environmental Claim asserted by an Environmental Authority or other third party, including but not limited to, an Environmental Claim seeking monetary damages, penalties or the performance of any action with respect to (i) injury to property; (ii) personal injury; (iii) damage to natural resources; (iv) non-compliance with Environmental Laws; or (v) Environmental Conditions.

"Third-Party Government Contractor" means a third-party, other than the United States, with which Hercules or Alliant has entered into a Government Contract.

"Transaction" means the transaction between the Parties effected by the Principal Agreement.

"United States" means the federal government of the United States of America, its executive departments, agencies, divisions, bureaus and subdivisions, including but not limited to, the Department of Defense, the Department of the Army, the Department of the Navy, the Department of the Air Force and the National Aeronautics and Space Administration.

For the sole purpose of this Article IV, a breach of a representation or warranty shall not be deemed to be "material" unless the total amount of the Environmental Claim that could be imposed on, incurred by or asserted against the Party making the representation in respect of the matters that were the subject of the representation or warranty exceeds $10,000.

ARTICLE FIVE

5. Transfer of Environmental Permits. Hercules shall reasonably cooperate with Alliant to facilitate the transfer to Alliant of the Environmental Permits issued to Hercules, GES and HDES with respect to the operation of the HAC Facilities and shall initiate and administer applications or notices for the transfer of any such Environmental Permit if Hercules, but not Alliant, has the legal authority to seek such transfer, provided however, that this provision shall not obligate Hercules to incur any cost or monetary obligation in connection with the transfer of such Environmental Permits, except such internal management or administrative costs as may reasonably be expected to be incurred in connection with the administration of an application or notice to transfer an Environmental Permit.

ARTICLE SIX

6. Government Responsibility Demands.

6.1 Initiation and Administration of Government Responsibility Demands.

(a) Alliant shall initiate and administer those Government Responsibility Demands as to which there is a reasonable legal basis to assert that an Environmental Claim arising from a HAC Facility or HAC Business that forms or may form the basis of an Environmental Indemnification Claim by Alliant against Hercules is a Federal Environmental Responsibility, as follows: (i) following the Closing, Alliant shall initiate and administer Government Responsibility Demands which Alliant has legal standing to enforce pursuant to Government Contract Law or Government Contracts to which Alliant is a party and shall use diligent efforts to secure reimbursement for the underlying Environmental Claim; and (ii) Alliant shall assume the administration of any Government Responsibility Demand initiated by Hercules prior to Closing and shall use diligent efforts to secure reimbursement for the underlying Environmental Claim.

(b) Alliant shall have no obligation to continue to administer a Government Responsibility Demand with respect to Environmental Claims arising from a HAC Facility or a HAC Business located on Non-Federal Land after two years from the date of the first assertion by the United States or the Third Party Government Contractor as to its position on whether the Environmental Claim underlying the Government Responsibility Demand constitutes a Federal Environmental Responsibility (the "Two Year Period"). Notwithstanding the foregoing, Alliant shall continue to administer a Government Responsibility Demand following the expiration of a Two Year Period if: (i) the United States or the Third Party Government Contractor has determined that the Environmental Claim underlying the Government Responsibility Demand is a Federal Environmental Responsibility; (ii) the United States or or the Third Party Government Contractor is paying reimbursement to Alliant pursuant to the Government Responsibility Demand; or (iii) Hercules agrees in writing to pay Alliant for reasonable costs incurred by Alliant in connection therewith, including but not limited to, reasonable attorneys' fees, experts' and consultant fees and other reasonable expenses, and to pay a reasonable hourly fee for time spent by Alliant personnel in administering such Government Responsibility Demand.

(c) Alliant shall have no obligation to continue to administer any Government Responsibility Demand with respect to an Environmental Claim arising from a HAC Facility or HAC Business located on Federal Land from the date a decision is rendered that the Environmental Claim underlying the Government Responsibility Demand is not a Federal Environmental Responsibility by either the United States Armed Services Board of Contract Appeals or the United States Court of Claims (the "Negative Decision"). Notwithstanding the foregoing, Alliant shall continue to administer such Government Responsibility Demand following the issuance of a Negative Decision if Hercules agrees in writing to pay Alliant for reasonable costs incurred by Alliant in connection therewith, including but not limited to, reasonable attorneys' fees, experts' and consultant fees and other reasonable expenses, and to pay a reasonable hourly fee for time spent by Alliant personnel in administering such Government Responsibility Demand.

(d) Hercules shall reimburse Alliant for any Environmental Claim subject to such Government Responsibility Demand, in the manner provided by Article IX of this Agreement, notwithstanding any contention by Hercules that such Environmental Claim is a Federal Environmental Responsibility upon: (x) with respect to a Government Responsibility Demand arising from a HAC Facility or HAC Business located on Non-Federal Land, the expiration of a Two Year Period, provided however, that Hercules shall have no obligation to reimburse Alliant to the extent the United States or a third party is paying reimbursement to Alliant with respect to the Environmental Claim pursuant to a Government Responsibility Demand; and (y) with respect to a

Government Responsibility Demand arising from a HAC Facility or HAC Business located on Federal Land, the issuance of a Negative Decision. Notwithstanding the foregoing, Hercules shall reimburse Alliant for an Environmental Claim pursuant to this Section 6.1(d) only to the extent the Environmental Claim would otherwise be subject to Hercules' obligation to indemnify Alliant under Article VIII of this Agreement and provided that Alliant shall reimburse Hercules to the extent of any subsequent allowance of, or other consideration or payment received by Alliant with respect to, the Government Responsibility Demand.

(e) Notwithstanding this Section 6.1, Hercules shall pay for the performance of Remedial Actions with respect to the Clearwater Facility and the Kenvil Facility in accordance with Article XII.

6.2 Negotiation of Government Contracts. With respect to the negotiation of Government Contracts to which Alliant is a party, Alliant shall use reasonable efforts to secure reasonably obtainable consents and other authorizations to facilitate addressing Environmental Conditions at HAC Facilities in a cost effective manner.

6.3 Status of Government Responsibility Demands. Following the Closing, on the first business day of February and August of every year, until the termination date for this requirement, Alliant shall deliver to Hercules a report summarizing the status of each Government Responsibility Demand administered by Alliant.

6.4 When No Government Responsibility Demand Is Made. If Alliant does not file a Government Responsibility Demand pursuant to this Article VI with respect to an Environmental Claim as to which Alliant seeks indemnification from Hercules pursuant to this Environmental Agreement, any dispute with respect to whether the Environmental Claim constitutes a Federal Environmental Responsibility shall be determined under the dispute resolution procedures established by Article XIV of the Principal Agreement, either in connection with a Reimbursement Request by Alliant or at such other time as either Party shall elect to submit the matter for dispute resolution.

ARTICLE SEVEN

7. Alliant's Assumption of Liabilities. Except as specifically provided in Articles VIII and XII of this Environmental Agreement, following the Closing, Alliant shall assume liability for all Environmental Claims associated with the HAC Business or the ownership, operation, use, management or control of the HAC Facilities, including but not limited to, all Environmental Claims associated with Environmental Conditions at the HAC Facilities or Environmental Claims associated with achieving compliance with Environmental Laws and with all Environmental Permits with respect to the operation of the HAC Facilities and the HAC Business. The foregoing notwithstanding, Alliant shall not assume liability for any and all Third-Party Claims arising from or relating to Off-Site Environmental Conditions resulting from the operation of the HAC Business prior to the Closing (i) at Federal Land, but only if such Third-Party Claims are first asserted against Alliant or Hercules after the tenth (10th) anniversary of the Closing; and (ii) at Non-Federal Land, but only if such Third-Party Claims are first asserted against Alliant or Hercules after the fifth (5th) anniversary of the Closing.

ARTICLE EIGHT

(c) Any and all Environmental Claims arising out of or relating to an Area of Environmental Concern if a Response to Environmental Conditions has already been implemented after the Closing, provided however, that this limitation shall not apply as to any Area of Environmental Concern in respect of which the implemented Response to Environmental Conditions consisted of no action;

(d) Any and all Environmental Claims arising out of or relating to Environmental Conditions on, at or from: (i) Federal Land resulting from the Release of materials that were not first regulated as Hazardous Substances prior to the tenth (10th) anniversary of the date of the Closing;

and (ii) Non-Federal Land resulting from the Release of materials that were not first regulated as Hazardous Substances prior to the fifth (5th) anniversary of the date of the Closing;

(e) Any and all Environmental Claims to the extent Alliant receives a Recovery with respect to such Environmental Claims; and

(c) Any and all Environmental Claims imposed on, incurred by or asserted against Hercules, or for which Hercules may be liable or obligated, arising out of or relating to an Area of Environmental Concern as to which a Response to Environmental Conditions has been implemented at a HAC Facility after the Closing, provided however, that Alliant shall not have any obligation to indemnify Hercules pursuant to this Section 8.3(c) as to any such Area of Environmental Concern in respect of which the implemented Response to Environmental Conditions consisted of no action;

(d) Any and all fines and penalties (including civil monetary penalties or settlement payments in lieu of penalties) imposed on, incurred by or asserted against Hercules, or for which Hercules may be liable or obligated, arising out of non-compliance with Environmental Laws or Environmental Permits at the HAC Facilities after the Closing, provided however, that such non-compliance is not attributable to the Release of Hazardous Substance prior to the Closing; and further provided that Alliant shall not have any obligation to indemnify or hold harmless Hercules from and against any fines or penalties related to non-compliance by Hercules (or consultants, contractors or subcontractors of Hercules) occurring after the Closing in the performance of a Remedial Action at the Kenvil Facility or the Clearwater Facility;

(e) Any and all Environmental Claims imposed on, incurred by or asserted against Hercules, or for which Hercules may be liable or obligated, arising from or relating in any way to the cost of addressing an Area of Environmental Concern at a HAC Facility to the extent exceeding the cost of the Lowest Cost Response; and

(f) Any and all Environmental Claims imposed on, incurred by or asserted against Hercules, or for which Hercules may be liable or obligated, arising from or relating to Alliant's breach of any of the representations and warranties set forth in Article IV of this Environmental Agreement or from Alliant's breach of its obligations under this Environmental Agreement, including but not limited to, its obligations pursuant to Article VI hereof.

8.4 Limitations on Alliant's Indemnification of Hercules. Notwithstanding anything in the Environmental Agreement to the contrary, Alliant shall have no obligation to indemnify Hercules with respect to the following:

(a) Any and all Environmental Claims to the extent Hercules receives a Recovery with respect to such Environmental Claims.

"Non-Sudden" for purposes of this Section 8.4(b) shall have a temporal meaning.

ARTICLE NINE

9. Procedures for Environmental Indemnification Claims.

9.1 Environmental Conditions Identified At or Prior to Closing. Alliant shall not be required to provide notice to Hercules of any Environmental Condition identified in the BEA or any Schedule attached to this Environmental Agreement.

9.2 Environmental Conditions Not Identified Before Closing.

(a) With respect to any Environmental Condition not identified in the BEA or any Schedule attached to this Environmental Agreement as to which Alliant is seeking or may seek indemnification from Hercules pursuant to this Environmental Agreement, Alliant shall promptly provide to Hercules a Notice of Environmental Conditions upon receiving Knowledge of the Environmental Condition. In any event, Alliant shall provide such Notice of Environmental Conditions within ninety (90) days from the day upon which Alliant receives Knowledge of such Environmental Condition. The Notice of Environmental Conditions shall set forth, to the extent Known by Alliant, the nature and the location of the Environmental Condition, the source and cause of the Environmental Condition, the identity and estimated quantity of the Hazardous Substance present and any response taken or planned to be taken by Alliant to address the Environmental Condition.

(b) Alliant's failure to notify Hercules of an Environmental Condition in accordance with Section 9.2(a) of this Environmental Agreement shall relieve Hercules of its obligation under the Environmental Indemnity as it pertains to any matter which should have been the subject of the notification to the extent, but only to the extent, as a direct and proximate result of such failure, there is a material adverse effect upon Hercules' rights under this Environmental Agreement.

9.3 Third-Party Claims. The procedures for indemnification with respect to Third-Party Claims shall be governed by Article XIII of the Principal Agreement; provided however, that in the event any Party is required by any Enforcement Notice or any judgment, order, settlement, agreement or other resolution of any Third-Party Claim to perform a Remedial Action, the performance of such Remedial Action shall be governed by this Environmental Agreement.

9.4 Reimbursement Procedures.

(a) A party shall submit requests for reimbursement of Environmental Claims to which it claims a right of indemnification pursuant Article VIII of this Environmental Agreement or of payment pursuant to Section 6.1(d) of this Environmental Agreement ("Reimbursement Request"), as provided herein:

(1) With respect to any Environmental Claim subject to Alliant's obligation to initiate and administer a Government Responsibility Demand under Article VI of this Environmental Agreement, Alliant shall not present a Reimbursement Request before the time provided by Section 6.l(d); and

(2) With respect to any Environmental Claim that is not subject to Alliant's obligation to initiate and administer a Government Responsibility Demand under Article VI of this Environmental Agreement, a Party may seek reimbursement of an Environmental Claim beginning on the first business day of January, April, July or September of each year following the Closing or as the Parties shall otherwise agree in writing.

(b) The Reimbursement Request shall identify or include the following as appropriate: (i) each Area of Environmental Concern to which the Reimbursement Request relates; (ii) any Enforcement Notice to which the Reimbursement Request relates; (iii) the Work Plan or Submission, if any, to which the Environmental Indemnification Claim or Reimbursement Request relates; (iv) the name of the contractor, consultant or other third party which received or will receive the monies related to the Reimbursement Request; (v) copies of all invoices (or other written requests for or evidence of payment) relating to the Reimbursement Request; (vi) a description of the work performed in connection with the Reimbursement Request; (vii) copies of any judgment, order, agreement, settlement or other document reflecting the resolution of a Third-Party Claim for which the Reimbursement Request is made; or (viii) any other factual basis for the Reimbursement Request.

ARTICLE TEN

10. Remedial Actions Under this Agreement.

10.1 Management of Remedial Actions. Except with respect to the Kenvil Facility and the Clearwater Facility, all material Remedial Actions at a HAC Facility subject or potentially subject to an Environmental Indemnification Claim under this Environmental Agreement shall be subject to the following requirements:

(a) At the Closing, Hercules shall designate a representative to receive information and consult with Alliant concerning Remedial Actions to be conducted by Alliant at the HAC Facilities (the "Hercules Environmental Representative"). From time to time, Hercules may designate a substitute Hercules Environmental Representative and alternate Hercules Environmental Representatives to serve if the primary Environmental Representative is unavailable. Alliant shall make its environmental personnel with responsibility for addressing Environmental Conditions at a HAC Facility reasonably available to the Hercules Environmental Representative to discuss Environmental Conditions at the HAC Facility that require or may require the performance of Remedial Actions subject to this Environmental Agreement.

(b) If requested by the Hercules Environmental Representative, Alliant shall provide to the Hercules Environmental Representative reasonable access to the HAC Facilities and copies of non-

privileged information reasonably necessary to evaluate the Remedial Actions to be taken with respect to a HAC Facility and the selection of consultants and contractors to implement such Remedial Activities, including but not limited to reports, analytical data, correspondence, directives, orders, documents submitted by Alliant to, or received by Alliant from, any applicable Environmental Authority in connection with a Remedial Action, and other non-privileged documents created or received by or on behalf of Alliant in connection with the Remedial Action. Alliant shall provide to the Hercules Environmental Representative reasonable prior notice of the initiation of any material Remedial Action and an opportunity to observe all such Remedial Actions performed.

(c) Alliant shall afford the Hercules Environmental Representatives a reasonable opportunity to confer with consultants and contractors retained to perform Remedial Actions.

(d) Upon Hercules' request, Alliant shall provide to the Hercules Facility Representative a copy of any work plan describing how a Remedial Action shall be conducted ("Work Plan") or any submission to be made to an Environmental Authority in connection with any Remedial Action ("Submission") as long as is reasonably practicable before the date that the Work Plan is scheduled to be implemented or the Submission is required to be submitted to any Environmental Authority, provided that Alliant shall have no obligation to provide drafts of such Work Plans and Submissions.

(e) In the event that the Hercules Environmental Representative provides comments to Alliant with respect to the performance of any Remedial Action, including but not limited to, the contents of any Work Plan or Submission, the Parties shall diligently confer in good faith to attempt to reach agreement on the subject matter of Hercules' comments. In the event agreement cannot be reached by the Hercules Environmental Representative and the Alliant personnel with responsibility for the matter, either Party may demand that any issue with respect to the Remedial Action be submitted to the Environmental Review Committee by written notice to each member of the Environmental Review Committee. Any such demand shall include a concise written statement of the issue to be considered by the Environmental Review Committee. The members of the Environmental Review Committee shall personally confer with respect to this issue as soon as is reasonably practicable, but in any event within thirty (30) days of receipt of the written demand. Decisions of the Environmental Review Committee shall require the agreement of both Parties and shall be final. If the Environmental Review Committee is unable to reach a decision, either Party may submit the issue for dispute resolution in accordance with Article XIV of the Principal Agreement, provided however, that if Alliant is unable, after good faith efforts, to obtain from the Environmental Authority an extension of the deadline, if any, to make a Submission or to implement a Work Plan or other Remedial Action and the issue is not resolved pursuant to this Section 10.1(e) by the expiration of such deadline, Alliant shall determine the action to be taken without prejudice to all rights of Hercules to contend that such action is not in accordance with this Environmental Agreement.

(f) Nothing in this Section 10.1 shall limit the right of Alliant to propose or implement a Remedial Action: (i) for which it shall not seek indemnification in accordance with this Environmental Agreement; or (ii) to take an emergent action that is necessary to address an imminent threat to human health or the Environment.

10.2 Performance of Remedial Action Under this Agreement. Any Remedial Action, or any part thereof, subject or potentially subject to an Environmental Indemnification Claim under this Environmental Agreement, shall be performed in a workmanlike manner, consistent with all applicable professional standards and in a cost effective manner not exceeding industry cost standards for comparable work. Without limiting the generality of the foregoing, the Party performing such a Remedial Action shall: (i) be responsible for the proper and lawful disposition of all wastes, including

but not limited to, soils and groundwater, generated in any Remedial Action; and (ii) obtain, maintain in full force and effect, and achieve material compliance with all Environmental Permits that are necessary for the performance of any Remedial Actions.

10.3 Maintenance of Engineering or Institutional Controls. As long as Alliant owns or operates a HAC Facility, Alliant shall properly maintain any Institutional Controls or Engineering Controls installed or employed at a HAC Facility in connection with any Remedial Action undertaken by Alliant, subject or potentially subject to an Environmental Indemnification Claim under this Environmental Agreement. The out-of-pocket fees, costs and expenses incurred by Alliant pursuant to this Section 10.3 shall be subject to Alliant's right of indemnification pursuant to Section 8.1(a) of this Environmental Agreement. The foregoing notwithstanding, Alliant may remove or discontinue any Institutional or Engineering Controls imposed on the HAC Facility at any time in its sole discretion, provided that Alliant at its sole expense complies with any conditions imposed by the Environmental Authority or required in compliance with Environmental Laws in connection with such removal or discontinuance (including the performance of any additional Remedial Action).

ARTICLE ELEVEN

11. Alliant New Jersey Facilities and ISRA. As to any Alliant New Jersey Facility as to which Alliant shall not have achieved Compliance with ISRA prior to the Closing, Alliant shall: (i) take all actions that are necessary to achieve Compliance with ISRA, (ii) establish and maintain in full force and effect any remediation funding source required under ISRA; and (iii) pay all fees, costs and expenses necessary or required to achieve Compliance with ISRA.

ARTICLE TWELVE

12. Kenvil and Clearwater Facilities.

12.1 Leases for Kenvil and Clearwater Facilities. The Parties specifically acknowledge that, in connection with the Transaction, Alliant shall execute leases for the Kenvil and Clearwater Facilities. The term of such leases shall be one year. Alliant shall have options to extend the leases for up to five additional one year terms. Should Alliant elect to extend its lease at the Kenvil Facility into a fourth year, Hercules and Alliant shall negotiate in good faith concerning a method by which Alliant will share in Environmental Claims incurred by Hercules arising from Releases, if any, occurring at the Kenvil Facility during Alliant's entire tenancy.

12.2 Compliance with ISRA—Kenvil Facility.

(a) ISRA Compliance Matter Arising from this Transaction. In connection with the ISRA Compliance Matter arising from the Transaction with respect to the Kenvil Facility, Hercules shall: (i) take all actions required to achieve Compliance with ISRA and the Remediation Agreement; (ii) establish and maintain in full force and effect any remediation funding source required under ISRA or the Remediation Agreement; and (iii) pay all fees, costs and expenses necessary or required to achieve Compliance with ISRA or the Remediation Agreement. Notwithstanding any provision of this Agreement to the contrary, Hercules shall have the sole and exclusive right and authority to propose, negotiate with the NJDEP concerning, and implement Remedial Actions at the Kenvil Facility required to achieve Compliance with ISRA or the Remediation Agreement, provided that Hercules shall implement Remedial Actions at such times, in such a manner and with such advance notice to Alliant as not to unreasonably interfere with Alliant's day to day operations at the Kenvil Facility.

(b) Future ISRA Compliance. In the event Alliant takes any action during its occupancy of the Kenvil Facility that requires the initiation of an ISRA Compliance Matter, including but not limited to, any closing of operations (as such term is defined under ISRA) by Alliant at the Kenvil

Facility, Alliant shall pay all filing fees and other costs of an administrative nature to achieve Compliance with ISRA. Subject to Alliant's obligation to indemnify Hercules pursuant to Article VIII of this Environmental Agreement for post-Closing Releases, as such obligation shall be modified by any agreement of the Parties described in Section 12.1 of this Environmental Agreement, Hercules shall take all actions and pay all other fees, costs and expenses to achieve Compliance with ISRA in connection with such ISRA Compliance Matter.

ARTICLE THIRTEEN

13. Miscellaneous.

13.1 Exclusive Remedy. Hercules and Alliant acknowledge and agree that, if the Closing occurs, the indemnification given by the Parties under this Agreement shall be the Parties' sole and exclusive remedies following Closing, each against the other: (i) with respect to Environmental Claims or arising out of Environmental Laws relating to: the HAC Business; the ownership, operation, management, use or control of HAC Facilities; Environmental Conditions at the HAC Facilities; the ownership, operation, management, use or control of Alliant Facilities; Environmental Conditions at the Alliant Facilities; and Compliance with ISRA; and (ii) with respect to any other subject matter of this Environmental Agreement. The Parties hereby waive and release any other rights, remedies, causes of action or claims as to which this Environmental Agreement sets forth the exclusive remedy. The foregoing notwithstanding, this Section 13.1 shall not apply to any and all Third-party Claims arising from or relating to Off-Site Environmental Conditions resulting from the operation of the HAC Business (i) at Federal Land, but only if such Third-Party Claims are first asserted against Alliant or Hercules after the tenth (10th) anniversary of the Closing; and (ii) at Non-Federal Land, but only if such Third-Party Claims are first asserted against Alliant or Hercules after the fifth (5th) anniversary of the Closing. Solely as to the claims described in the preceding sentence, each Party shall retain against the other all rights, remedies, causes of action or claims they have or may have under Environmental Laws or otherwise.

13.2 Third Party Actions. Either Party may, but shall have no obligation to, institute an action against any third party, at any time and at its sole expense, with respect to Environmental Claims for which that Party is, or may be, entitled to indemnification pursuant to this Environmental Agreement, provided however, that with respect to all such Environmental Claims as to which Alliant is seeking recovery or reimbursement as a Federal Environmental Responsibility pursuant to Article VI of this Environmental Agreement, Hercules shall not institute any action against the United States without Alliant's prior written consent, which consent shall not be unreasonably withheld.

13.3 Incorporation of Terms of Principal Agreement.

(a) The provisions of Articles XIII, XIV, XV of the Principal Agreement are incorporated herein and made a part hereof.

(b) Except as specifically set forth in this Environmental Agreement, this Environmental Agreement shall constitute the entire agreement of the Parties with respect to environmental matters of any kind or nature arising from or relating in any way to the HAC Business, the business of Alliant or the ownership, operation, use, management or control of the HAC Facilities or the Alliant Facilities.

(c) In the event of any conflict between the terms and conditions of this Environmental Agreement and the Principal Agreement, this Environmental Agreement will control with respect to environmental matters.

13.4 Schedules to Environmental Agreement. The Parties acknowledge and agree that they are entering into this Environmental Agreement prior to the preparation and delivery of the Schedules referenced herein and that these Schedules shall be delivered prior to the Closing.

13.5 Notices

Schedule EA 4.1(a)(1)

PERMITS

Except as set forth in this Schedule EA 4.1(a)(1)¹, to the Knowledge of Hercules, GES and HDES, all Environmental Permits necessary for the operation of the HAC Facilities and the HAC Business, as they have been operated within the two (2) years prior to Closing, have been issued, and all such Environmental Permits are in full force and effect, and all appeal periods for such permits have expired.

Open Burning Permit for disposal of rubbish, garbage or trade waste, or buildings or structures, or waste explosives materials. Permit application was not submitted to the NJDEP within the required time frames. Previous permit expired February 20,1994 and has not been renewed to date. Permit application process is now underway.

ABL

Renewed NPDES and stormwater permit: The NPDES portion of the application has been completed and submitted. The stormwater portion of the application has been submitted with incomplete data. Collection of composite stormwater samples are still required. It is expected to be complete by spring 1995. State has agreed to administratively continue the existing water pollution control permit (which covers only one discharge). Additional outfalls were added in the updated permit application. West Virginia is now requesting a revised permit application based on further consolidation of outfalls and the facility changes since the application was submitted. The request came from a January 1995 wastewater inspection. No immediate date for submittal was requested by the State.

Kenvil

The facility's NPDES permit expired in 1991. The facility submitted a permit renewal application in a timely manner that year. The State has not yet acted on issuing the new permit. However, since the permit application was filed in a timely manner, the facility is covered by its existing (old) permit.

Stormwater discharges from the facility were included in the 1991 NPDES permit application. The current stormwater discharge regulations require submittal of a permit application for stormwater discharge, except if covered by an existing permit (or application). Since this was the case, the facility does not currently have a stormwater permit, but it will be covered when the State issues the facility's new permit.

Water Allocation Permit expired January 1993. State has granted blanket extension to all permit holders.

Air Permits: Pursuant to an Administrative Consent Order (ACO) dated April 1993, Hercules is obligated to submit administratively complete permit/certificate applications to the NJDEP for all new or altered regulated operations at the Kenvil facility. These applications have not yet been submitted; however, Hercules is in the process of completing the applications.

Open Burning Permit for disposal of rubbish, garbage or trade waste, or buildings or structures, or waste explosives materials; Permit application was not submitted to the NJDEP within the required time frames. Previous permit expired February 20, 1994 and has not been renewed to date. Permit application process is now underway.

▇▇▇▇▇▇▇▇

The State has issued the new wastewater discharge permit. While Texas has their own wastewater permitting program, they do not have authority to implement the federal NPDES permit program. ▇▇▇▇▇▇▇▇ filed an application with EPA in a timely manner. However, EPA has not acted upon it. The

EPA has replied that the permit application was administratively complete, and the old permit appears to be in administrative continuance until the application is acted upon. The expected permitting date is unknown at this time; however, closure of operations at ▇▇▇▇▇▇▇▇ (operations moving to ABL) is expected prior to permit issuance.

^interim Status for RCRA Subpart X (open burning) is not listed here as a permit which is not issued or not in full force, as the requirements have been met by submission of the applications. The McGregor, TX facility is the only facility with a Subpart X permit in force (issued by Texas and approved by EPA).

Schedule EA 4.1(a)(2)

Except as set forth in this Schedule EA 4.1(a)(2), to the Knowledge of Hercules, GES and HDES, Hercules, GES and HDES are in compliance in all material respects with the Environmental Permits issued for the operation of the HAC Facilities and the HAC Business.

ABL

The sewage treatment plant has been experiencing periodic violations (associated with seasonal precipitation) of flow limitations due to infiltration of precipitation into the facility's old sewer lines. A study of the sewer lines is planned, and a new treatment plant with additional capacity for flow equalization has been funded by the Navy. Construction is expected in the next year.

Kenvil

An Administrative Consent Order was entered into between Hercules and the NJDEP concerning the VOC emissions at the Kenvil facility. The ACO set forth a compliance schedule for controlling or eliminating the emissions of certain equipment at the plant in order to come into compliance with the New Jersey Air Pollution Control Act. The ACO also required that Hercules administratively submit permit/certificate applications to the NJDEP for all new or altered regulated operations at the Kenvil plant. Pursuant to a letter from the NJDEP dated March 9, 1995, steps to comply with the terms of the ACO are currently underway.

Additionally, other air emissions permit violations have been cited by the NJDEP based on a November 1, 1994 NJDEP site inspection. Hercules is reviewing with the NJDEP the status of these citations.

The lab certification for drinking water analysis is pending revocation due to failure to submit quality assurance data as requested by the NJDEP. Issue will be resolved by the next quality assurance data request from the NJDEP.

The sewage treatment plant at Sunflower has experienced recent chronic fecal coliform limit violations of its NPDES permit. Studies are being conducted with Army assistance to determine the cause, and the facility is installing a disinfection system to eliminate violations in the interim.

Schedule EA 4.1(a)(3)

Except as set forth in this Schedule EA 4.1(a)(3), to the Knowledge of Hercules, GES and HDES, there is no reason that the Environmental Permits issued to Hercules, GES and HDES cannot be transferred to Alliant in the Ordinary Course of Business without undue cost or delay to Alliant.

ABL

The RCRA hazardous waste management permit transfer to Alliant is being delayed due to complications with the ability of the Navy to sign the permit transfer as the owner (indicating Alliant as the operator) until the contract has been novated. This may cause a delay of several months.

ABL

•: Limestone Road Superfund site; filed May 1994
Shipment of waste from ABL to Limestone Road site. Volume and nature of waste must still be determined.

Hercules' contribution to settlement is being sought by the parties who have performed the RI/FS and the capping and fencing at the site. Approximately $4 Million is expected to be spent through completion of the RI/FS. Hercules has arranged for the disposal of 16 drums identified as ours during the capping work. Contents of document repository in Philadelphia will be reviewed.

•: Archem Company site, last operated by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Chemical Company, USA, Houston, TX

ABL received a 104(e) information request in August 1993. Hercules' response indicated Archem had been a supplier of product to both our ABL and Bacchus facilities. It appears the majority of material supplied to Hercules was K-7 (a curing agent).

On January 18, 1994, Hercules received a request from the Texas Water Commission (TWC) to participate in a removal action at the site. Past costs incurred by the TWC are $721,673. Hercules is preparing a response denying responsibility as a potentially responsible party and declining to participate in the removal action.

•: Municipal Industrial Disposal Company site in ▇▇▇▇▇▇▇▇▇ Township, Allegheny County, PA

Hercules received a §104(e) information request in May 1993. Our investigation revealed that in September 1980 thirty (30) drums of inorganic waste sludge were shipped through a transporter who listed MIDC as the disposal location. However, no disposal certificate was ever received to confirm that the waste did indeed get disposed of at MIDC. Further, the contract with ABL and the transporter listed another disposal location as the disposal site. Finally, the transporter was later arrested by the authorities for disposing of wastes at locations not on the manifests. Therefore, Hercules has no documentation or information to support waste actually being disposed of at MIDC.

Schedule EA 4.1(c)

HAZARDOUS SUBSTANCES

Except as set forth in this Schedule EA 4.1(c), to the Knowledge of Hercules, GES and HDES, there are no Hazardous Substances stored at, located on or disposed of at or from any of the HAC Facilities in material violation of any Environmental Law or which could be required to be remediated under any Environmental Law.

The following list contains references to reports on remedial investigation studies at the facilities where documentation of known or suspected hazardous substances are discussed. Additionally, notation is made of known releases of hazardous substances which have occurred which may require further investigation or remediation since these studies have been conducted.

All other releases (spills) of Hazardous Substances which may have occurred at the facilities over time are believed to have been appropriately reported to regulatory agencies and appropriately remediated at that time and are, therefore, not listed here.

•: Draft Work Plan for the RI/FS; May 1994
•: Acid spill area near the Plant 1 Boilerhouse. One-time spill occurred in August 1992. Approximately 6500 lbs. of diluted sulphuric acid was released. Acid leaked into neutralization pit. Release is being investigated as a SMWU but no further remediation is anticipated.
•: Former ammonium perchlorate wastewater discharge areas (untreated to ground, now stopped). Practice occurred from early 1970s until 1993. No way to quantify amounts that could have been released. Remediation, if any, will be addressed under CERCLA.
•: K044 sludge in aeration basins at sewage treatment plant. Basins built in 1962. Approximately 12,000-15,000 gallons of sludge could be located in west basin; much less gallonage in east basin. Remediation of basins is planned when demolition of sewage treatment plant occurs. Due to leakage of west basin, this site is being added to the SWMU list for investigation under CERCLA.
•: Oil on ground from compressor houses 252 and 341. Compressor in Building 341 has been in operation since early 60s. The period of operation of the compressor in Building 252 is unknown but assumed to be approximately the same time frame as Building 341. In 1992 oil/water separators were installed at both buildings. Quantities discharged are unknown, but very rough estimates calculate approximately 50 gallons per year per building.

In 1993 excavation of approximately eight tons of soil from Building 252 was removed and landfarmed. Future remedial action, if any, will be handled under the RCRA corrective action pursuant to CERCLA oversite.

•: Several fuel oil tank leaks at Plant 2 boiler house. Discharges may have been ongoing since mid-1960s. No spill has exceeded 30 gallons, but no knowledge of how many spills may have

occurred. Approximately 170 tons of soil removed in 1994 and landfarmed. Future action may be required under State law.

•: Chlorobenzene, BTEX, diesel organics, oil and grease detected at F-Well, Building 215 (old well found after demolition of Building 215). During demolition work in late 1994, F-Well was discovered. F-Well put in place in early 1960s, but was never used as production well because of sediment problems. Later expansion of Building 215 covered well over. Future remedial action, if any, will be handled under CERCLA.

Compliance With Environmental Laws

Alliant Techsystems is in compliance in all material respects with environmental laws applicable to the business of Alliant except:

1. Littleton, Colorado, a.k.a. Metrum facility. The ground water exceeds state standards for volatile organic compounds. This ground water contamination is a result of past practices at the site. Contaminated groundwater extends beyond the property boundary which is non compliant with the Colorado Water Quality Control Commission rules. Alliant has been voluntarily studying this site since 1990 and in cooperation with the Colorado Department of Environment and Public Health. The remediation plans are being finalized with expected implementation in FY 1996.

2. Ground water contamination at Mukilteo is being investigated. In 1990, ground water samples from the main plant indicated some elevated levels of some metals and organics. There seems to be a question whether these samples are valid. We need to resample to determine if there are elevated levels of metals and organics. The State had not addressed this possibility of contamination except by a letter which indicates that this site may have been placed on tentative Superfund list.

3. The Qui Tam lawsuit, U.S. ex rel Fallon v. Accudyne, filed September 23, 1994 in the United States District Court for the Western District of Wisconsin, alleges a number of environmental violations at the Accudyne facility. Generally, the complaint includes alleged violations of RCRA for improper storage and disposal of hazardous waste and failure to have an adequate training program for employees, Clean Water Act for improper discharges, and Emergency Planning and Community Right-to-Know Act reporting. Refer to the complaint for the specific allegations.

4.2(b)(1)

ALLIANT ENVIRONMENTAL PERMITS ISSUED

Schedule EA 4.2(b)(1)

Issued Permits

Alliant Techsystems has obtained all environmental permits necessary for the operation of Alliant facilities and business. All environmental permits necessary for the operation of Alliant facilities have been issued to Alliant and are in full force and effect except:

1. With regard to the ▇▇▇▇▇▇▇ facility, a request has been made to the Minneapolis Metropolitan Waste Control Commission for a determination if an industrial waste discharge permit is necessary for the limited discharge of chemically treated cooling water to be discharged into the sanitary sewer.

2. For both ▇▇▇▇▇▇▇ and TCAAP, an air emissions permit application has been submitted to the MPCA as of April of 1992. However the MPCA has indicated that it will not act upon the application and issue a permit until the submittal of either a Registration or Title V permit application due in 1995. Alliant is currently in compliance via the April 1992 submittal of the two facility air emissions permit applications.

3. Ferrulmatic is in the process of applying for a sanitary sewer discharge permit to allow the discharge of approx. 500 gallons of non hazardous water into the sanitary sewer.

4. Alliant is working with the NRC to amend an existing Alliant license to store depleted uranium contaminated sand at ATLF (Joliet Army Ammunition Plant). This sand was discovered the summer of 1994. It appears that it was residual from a cleanup in 1989. The NRC was notified and a cleanup was conducted. As part of the remediation effort, the sand is now being accumulated on site, awaiting final disposition.

5. Accudyne does not have an air emissions inventory. We expect to submit the required Title V documentation in September of 1995.

6. The Alliant Techsystems Proving Grounds (ATPG) is conducting open burn and open detonation under a compliance plan with the MPCA while the Subpart X permit application is being developed.

7. With regard to air permits, the required Title V documentation will be submitted as required for each facility.

Schedule 4.2(b )(2)

ALLIANT COMPLIANCE WITH PERMITS

Schedule 4.2(b)(2)

Compliance with Permits

Alliant Techsystems is in compliance in all material respects with the environmental permits issued to Alliant except that:

1. Ferrulmatic Operations, New Jersey. An in house audit at Ferrulmatic has revealed that the New Jersey air permits may have been done incorrectly. A letter of intent in accordance with the NJDEPE "amnesty program" will be filed as well as a request for a representative of NJDEPE to review the Ferrulmatic permits.

2. At the Alliant Techsystems LAP Facility at the Joliet Army Ammunition Plant, a possible storage violation was identified during an IEPA inspection on November 28, 1994. Hazardous waste in the 90 day generator accumulation area within Group 3-A may have been stored longer than 90 days. Alliant is not expecting nor has received a Notice of Violation at this time.

3. The NPDES permit at the ▇▇▇▇▇▇▇ facility is pending. All comments are due by March 20, 1995. We have not been given any indication that the permit will not be approved. The major issue with this permit deals with the levels of metals which are being discharged into the lagoon. The ▇▇▇▇▇▇▇ processes do not discharge the subject metals in a manner in which they could enter the lagoon.

4. ▇▇▇▇▇▇▇ is developing its corrective action program for the facility RCRA permit.

Schedule 4.2(c)

EXISTING CLAIMS ASSERTED OR THREATENED
WITH RESPECT TO ALLIANT

Schedule EA 4.2(c)

Existing Claims

Alliant Techsystems has no knowledge that any environmental claim has been asserted or threatened with respect to any:

(i) alleged violation by Alliant of any environmental laws or the terms and conditions of any environmental permits issued to Alliant , except:

Case Name: U.S. ex rel Fallon v. Accudyne
Date Filed: September 23, 1994
Former and one current employees in conjunction with an environmental non-profit group have filed a Qui Tam action under the False Claims Act alleging inter alia, environmental violations.

Case Name: State of Wisconsin v. Accudyne Corp.
Date Filed: January 18, 1995
Alleged violation of Emergency Planning and Community Right to Know Act reporting by Accudyne Corp. prior to Alliant's acquisition of it. There is a stipulation between the State and Alliant staying Alliant's need to file an answer until after the Accudyne Qui Tam action has been tried.

(ii) alleged failure by Alliant to have any environmental permits, except:

None.

(iii) generation, treatment, storage, recycling, transportation, disposal or release of any hazardous substance generated by Alliant, except:

(a) Honeywell and Alliant share responsibility for a number of Superfund sites. While settlement agreements have been entered into with respect to these sites, there are reopeners which in all cases should be de minimis. These sites include:

▇▇▇▇▇ Airport Landfill
Denver, Colorado
Settled

Envirochem Superfund Site
Indianapolis, Indiana
Settled

Northside Sanitary Landfill
Zionville, Indiana
Settled

Great Lakes Asphalt Site
Indianapolis, Indiana
Settled

Waste Disposal Engineering Landfill
Andover, Minnesota
Settled

Western Processing Site
Kent, Washington
Settled

Industrial Solvents Chemical Company
York Haven, Pennsylvania
Settled

(b) Superfund sites in which Alliant is a PRP:

Union Scrap III
Minneapolis, Minnesota
The settlement in this case is being finalized. Expected contribution of Alliant $30,000.

East Bethel Landfill
Anoka County, Minnesota
Settled, but there is a possibility of reopener if the remedy costs more than expected.

Tulalip Landfill
Snohomish County, Washington
A request for information has been received by the U.S. EPA.
A de minimis buy out is expected.

Solvents Recovery Service of New England
Southington, Connecticut
A notice of potential liability has been received by the U.S. EPA.
A de minimis buy out is expected.

(d) A contribution claim has been filed for the following site:

Case Name:    Eveready Battery Company v. Alliant Techsystems, et al.
Date Filed:    August 11, 1994.
Description:    This case is a contribution action for the clean up of the ▇▇▇▇▇▇▇ Brothers Landfill in Bennington, Vermont. It arises from the purchase of batteries by Honeywell in the late 1960's and early 1970's from Eveready (Union Carbide). Honeywell did not contribute any waste directly to the landfill. The plaintiff seems to be relying on ▇▇▇▇▇ theories.

(e) Alliant is operating under an administrative consent order or Record of Decision for the pump and treat of ground water at the following sites:

1. Trio Solvent Site.
Record of Decision with the MPCA.

2. Signal Analysis Center.
Currently operating; there is a draft consent order which should be completed with in 2-3 months.

3. New Brighton Plume Groundwater Treatment Systems.
Record of Decision with the MPCA.

(f) Alliant's threatened litigation regarding environmental matters:

1. The ground water contamination at the Littleton, Colorado facility has moved under the neighboring property. This property is owned by Creek Dry Road, Inc. which is owned by Sandoz Corp. Sandoz has threatened to ▇▇▇ Alliant for the decrease of value of its property because of the contamination. We have entered into an agreement to toll the statute of limitation for this matter in order to allow Sandoz time to sell this property and avoid a lawsuit.

2. Alliant has read in the newspapers that the city of Superior, Wisconsin with other nearby cities, are considering suing Honeywell and other potentially responsible parties, for the removal of hundreds of 55-gallon barrels which were dumped into Lake Superior over 20 years ago. The facts are unclear but Honeywell would likely look to Alliant to defend this suit as it appears to originate from the defense business.
