3. Debtor Remains Liable. Anything herein to the contrary notwithstanding, (a) Debtor shall remain liable under the contracts and agreements included in the Collateral to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been executed, (b) the exercise by Holder of any of its rights hereunder shall not release Debtor from any of its duties or obligations under the contracts and agreements included in the Collateral, and (c) Holder shall not have any obligation or liability under the contracts and agreements included in the Collateral by reason of this Agreement nor shall Holder be obligated to perform any of the obligations or duties of Debtor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

(a) Debtor shall keep its principal place of business and chief executive office and the office where it keeps its records concerning the Receivables, if any, at 000 X. Xxxxxx Xxxxxx, Xxxxxx Xxxx, XX, 00000.

Until Holder notifies Debtor to the contrary, each Debtor shall make collection of all Receivables and other Collateral in the ordinary course of business. Holder may, at any time after the occurrence and during the continuance of any “default” or “event of default” under the Notes or the Note Indenture (each an “Event of Default”), notify all account debtors relating to any Receivables that Debtor’s Receivables have been assigned to Trustee for the benefit of Holders and of Holders’ security interest therein, and may collect them directly and charge the collection costs and expenses to Debtor. So long as an Event of Default has occurred and is continuing, Debtor, at Trustee’s request, shall execute and deliver to Trustee for the benefit of Holders such documents as Trustee shall require to grant Trustee access to any post office box in which collections of Receivables are received.

Debtor shall use its best efforts to resolve any dispute, right of setoff, counterclaim, or defense with respect to all or any part of the Collateral. Debtor shall cause to be terminated any financing statement or other security instrument with respect to its Collateral, except such as may exist or as may have been filed in favor of Holder, and subject to the July Pledge. Debtor shall defend Holder’s right, title, and special property and security interest in and to the Collateral against the claims of any person or entity, subject to the July Pledge.

(c) Debtor shall maintain its Collateral in good condition and shall not use the same in violation of any law or any policy of insurance thereon, and shall make such Collateral available for inspection by Holder. Debtor shall not permit any of its Collateral or any part thereof to be affixed to or otherwise become a part of any real or personal property, without first making arrangements satisfactory to Holder to protect Holder’s security interest therein. Upon Trustee’s request, Debtor shall make appropriate notations in its ledger to indicate Holder’s interest in the Collateral.

(d) All and any Pledged Securities have been delivered to Trustee, along with duly executed powers of attorney under the July Pledge Agreement, and will remain with Trustee after release of the July Pledge, as collateral under this Agreement, and duly executed powers of attorney shall be delivered to the Trustee under this Agreement. Collateral shall remain at the location(s) designated by Debtor. Debtor shall not cause or permit the removal of any item of the Collateral from its possession, control or risk of loss, or from the location specified herein, other than removal in connection with possession of Collateral by Trustee for the benefit of Holders or by a bailee selected by Trustee who is holding the Collateral for the benefit of Holder as agent for Holder.

(e) Debtor agrees that from time to time, at the expense of Debtor, Debtor will promptly execute and deliver all further instruments and documents, and take all further action, that may

be necessary or desirable, or that Trustee for the benefit of Holder may reasonably request, in order to perfect and protect any security interest granted or purported to be granted hereby or to enable Trustee to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, Debtor will upon such request execute and file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as Trustee may request, in order to perfect and preserve the security interest granted or purported to be granted hereby. Debtor shall furnish to Trustee any information that Trustee may from time to time request concerning any covenant, provision or representation contained herein or any other matter in connection with the Collateral or the Note Indenture.

(f) Debtor hereby authorizes Trustee, but Trustee shall have no obligation, to file one or more financing or continuation statements, and amendments thereto, related to all or any part of the Collateral without the signature of Debtor. A photocopy or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law.

(g) Debtor will furnish to Holder from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as Holder may reasonably request, all in reasonable detail.

(h) Debtor hereby agrees to and makes the covenants regarding the operations and assets of Borealis Mining set forth in Section 8.2 (d) – (i) of the Note Indenture as if set forth fully herein.

6. Insurance. Debtor shall maintain and shall require Borealis Mining to maintain adequate insurance on all of its properties in such amounts with such insurers as are standard practice within the industry of the Debtor. If Debtor receives benefits arising from any insurance policy covering Collateral, the net cash proceeds shall be deemed Collateral under this Agreement and paid to the Trustee for the benefit of the Holders.

7. Holder Appointed Attorney-in-Fact. Debtor hereby irrevocably appoints Trustee, for the benefit of Holders, the attorney-in-fact of Debtor, coupled with an interest and with full authority in the place and stead of Debtor and in the name of Debtor, Holder or otherwise, from time to time in Trustee’s discretion, to take any action and to execute any instrument which Trustee may deem necessary or advisable to accomplish the purposes of this Agreement, including:

(a) To obtain and adjust insurance required to be paid to Holders pursuant to Section 6;

(b) To ask, demand, collect, xxx for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in connection with the Collateral;

(c) To receive, endorse, and collect any drafts or other instruments, documents and chattel paper, in connection therewith; and

(d) To file any claims or take any action or institute any proceedings which Trustee may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of Holder with respect to any of the Collateral.

The provisions of this Section 7 shall terminate upon termination of the Note Indenture and the complete and final satisfaction and repayment of all obligations of any of Debtor under the Notes and Note Indenture, whether for principal, interest, expenses or otherwise.

8. Holder May Perform. If any Debtor fails to perform any agreement contained herein, Trustee, for the benefit of Holders, may perform, or cause performance of, such agreement, and the expenses of Trustee incurred in connection therewith shall be payable by Debtor.

9. Trustee/Holder’s Duties. The powers conferred on Trustee hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, Trustee shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral, subject to the July Pledge. Trustee shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which Trustee accords its own property. For the sake of clarity, Trustee is holding the Collateral as trustee to the Holders of the Notes pursuant to the terms of this Agreement, and is also holding the Collateral (as such term is defined in the July Pledge Agreement) as trustee to the holders of the July Notes pursuant to the terms of the July Pledge Agreement.

10. Remedies.

(a) If any Event of Default shall have occurred and be continuing subject to the terms of the July Note Subordination (as defined in the Note Indenture):

(i) Trustee, for the benefit of Holders, shall have all of the rights, remedies and privileges with respect to repossession, retention and sale of the Collateral and disposition of the proceeds thereof as are afforded to Trustee or Holders by this Agreement and the applicable sections of the UCC (whether or not the UCC applies to the affected Collateral).

(ii) Without limiting the scope of the foregoing clause (i):

(1) Trustee, for the benefit of Holders, shall have the right to sell, resell, assign, and deliver the Collateral for sale, provided that only such portion of the Collateral as is necessary to satisfy the obligations arising under the Notes or Note Indenture may be sold by Trustee, for the benefit of Holders. Trustee will give Debtor, to the extent notice of sale shall be required by law, at least ten (10) days’ prior written notice of the time and place of any sale of the Collateral or the time after which any private sale or any other intended disposition of the Collateral is to be made. Any such notice shall be deemed to meet any requirement hereunder or under any applicable law (including the UCC) that reasonable notification be given of the time and place of such sale or other disposition. Such notice may be given without any demand for performance or other demand, all such demands being hereby expressly waived by Debtor. Trustee shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Trustee may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(2) In the event of any such sale or sales, the Collateral so purchased shall be held by the purchaser absolutely free from any and all claims or rights of Debtor of every kind and nature whatsoever, including any equity of redemption or similar rights, all such equity of redemption and similar rights being hereby expressly waived and released by Debtor. Trustee may disclaim warranties of

title, possession, quiet enjoyment and the like. The proceeds of the sale of any Collateral, together with any other additional collateral security at the time received and held hereunder, shall be received and applied: first, to the payment of all of the Trustee’s costs and expenses of sale, including reasonable attorneys’ fees; second, to the payment of the obligations of Debtor and the other parties under the Notes or Note Indenture, in such order of priority as Trustee shall determine; and third, any remaining proceeds shall be paid to shall be paid over to the applicable Debtor or to whomsoever may be lawfully entitled to receive such surplus.

(3) Debtor recognizes that Trustee may be unable to effect a public sale of all or any part of the Collateral by reason of certain prohibitions contained in the Securities Act of 1933, as amended (the “Securities Act”), or other applicable laws, rules or regulations, but may be compelled to resort to one or more private sales to a restricted group of purchasers who will, among other things, be obliged to agree to acquire the Collateral or any part thereof for their own account, for investment and not with a view to the distribution or resale thereof. Debtor agrees that private sales so made may be at prices and on terms less favorable than if the Collateral were sold at public sales, and that Holder has no obligation to delay the sale of any Collateral for the period of time necessary to permit the Collateral to be registered for public sale under the Securities Act or any other applicable law, rule or regulation. Debtor agrees that private sales made under the foregoing circumstances shall be deemed to have been made in a commercially reasonable manner.

(iii) Debtor shall take any action that Trustee may request in the exercise of its rights and remedies under this Agreement in order to transfer and assign to Trustee, or to such one or more third parties as Trustee may designate, or to a combination of the foregoing, any or all of the Collateral.

(iv) Trustee shall have the right, for and in the name, place and stead of Debtor, to execute endorsements, assignments and other instruments of conveyance or transfer with respect to all or any of the Collateral, and in connection therewith, Debtor hereby irrevocably appoints Trustee, its officers, employees and agents, or any of them, as attorneys-in-fact for Debtor to execute, deliver, file and record such items for Debtor and in Debtor’s name, place and stead. This power of attorney, being coupled with an interest, shall be irrevocable.

(b) If in connection with the exercise by Trustee of any power, right, provision or remedy granted pursuant to this Agreement, or in order to effectuate the purposes and intent of this Agreement, any consent, approval, registration, filing, qualification or authorization of any governmental authority is required, Debtor will execute and deliver all applications, certificates, instruments and other documents and papers that Trustee may be required to obtain for such governmental consent, approval, registration, filing, qualification or authorization.

11. Waivers and Amendments. No provision of this Agreement may be amended, waived or modified without the written consent of all the Holders and the Debtor. Trustee, for the benefit of Holders, may exercise its rights with respect to the Collateral held hereunder without first or simultaneously resorting to any other collateral or sources of repayment or reimbursement; and without being obligated to consider or take notice of any right of contribution, reimbursement, subrogation or marshaling of assets which Debtor may have or claim to have against any person or persons or with respect to any other collateral; and Trustee, for the benefit of Holders, may release any and all other

collateral it may now or hereafter have to secure repayment of the Notes, all without affecting or impairing its rights with respect to the Collateral. The failure by Trustee to insist upon Debtor’s strict performance of this Agreement or the delay or the failure by Trustee, for the benefit of Holders, to exercise Holder’s remedies hereunder shall not be deemed a waiver of such default, and shall not be a waiver by Holder of any of Holder’s rights or remedies hereunder or at law or in equity. A waiver on any one occasion shall not be construed as a bar to or waiver of any right and/or remedy on any future occasion.

12. Addresses for Notices.

(a) Except in the case of notices and other communications expressly permitted to be given by telephone (and subject to Section 12(b)) all notices and other communications provided for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by facsimile, as follows:
