(B) The Borrower is a wholly owned subsidiary of the Pledgor.

(C) Pursuant to a bank guarantee facility made under the Amended and Restated Loan Agreement, the Issuing Bank issued a bank guarantee dated January 7, 2014 (the “Guarantee”), made between the Issuing Bank, as guarantor and Total E&P Norge AS, a Norwegian company (the “Beneficiary”), as beneficiary, whereby the Issuing Bank, as guarantor, agreed to guarantee an amount of NOK 115,199,285.85 relating to a certain Facilities Contract and a Lease and Services Contract (both as defined in the Amended and Restated Loan Agreement) made between the Borrower and the Beneficiary.

(D) The Pledgor holds one million (1,000,000) subordinated units (the “Pledged Interests”) in KNOT Offshore Partners LP, a limited partnership organized under the laws of the ▇▇▇▇▇▇▇▇ Islands (the “Company”).

(E) To secure obligations owing in connection with the Guarantee, the Pledgor will hereby pledge to the Pledgee, among other things, the Pledged Interests in existence on the date hereof which are further described on Part A of Schedule 1 hereto.

NOW, THEREFORE, in consideration of these premises and for other valuable consideration, the receipt and adequacy of which the parties hereby acknowledge, the Pledgor and the Pledgee hereby agree as follows:

5

(g) it has not (i) filed or consented to the filing of any financing statement or analogous document under the UCC or any other applicable laws covering any Pledged Collateral, or (ii) consented to, and is not otherwise aware of, any other security interest in, any Pledged Collateral, in each case other than in respect of the Pledgee pursuant to this Agreement; and

(d) it shall furnish to Pledgee from time to time statements and schedules further identifying and describing the Pledged Collateral as Pledgee reasonably requests, all in reasonable detail;

6

(f) it shall not consent to any termination of or amendment to the Organizational Documents or other organizational documents of the Company that could reasonably be expected to adversely affect the Pledged Collateral, the Pledgor’s rights in the Pledged Collateral, the validity, perfection or priority of the security interests of the Pledgee in the Pledged Collateral, the rights and remedies of the Pledgee under this Agreement or any other Finance Document or their ability to exercise the same, or cause an Event of Default to occur; and

(g) it shall indemnify the Pledgee from, and hold it harmless against, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Pledged Collateral or in connection with the transaction contemplated by this Agreement.

SECTION 6. Delivery of Additional Collateral. If the Pledgor shall become entitled to receive or shall receive any additional Pledged Collateral, including any equity interests, option or rights, whether as an addition to, in substitution of, or in exchange for or conversion of any of the Pledged Interests, to the extent that such additional Pledged Collateral is in certificated form, the Pledgor agrees to (A) arrange that the same be delivered in certificated form directly to the Pledgee or (B) if direct delivery thereof is not practicable, to accept such additional Pledged Collateral as the agent of the Pledgee and to hold the same in trust for the benefit of the Pledgee and to deliver the same forthwith to Pledgee, in each case under clauses (A) and (B) in the exact form received, with the endorsement of the Pledgor when necessary and/or appropriate undated instruments of transfer duly executed in blank, in each case as additional collateral security for the Obligations.

SECTION 7. General Authority; Power of Attorney. The Pledgor hereby:

(a) agrees that all rights of the Pledgee hereunder, its security interest and all obligations of the Pledgor hereunder will be absolute and unconditional, irrespective of (i) any renewal, extension, modification, acceleration, compromise, amendment, supplement, termination, sale, exchange, waiver, surrender, release, lack of validity or enforceability of any Finance Document, any agreement with respect to any of the Obligations or any other agreement or instrument relating to any of the foregoing or any guarantees or other collateral security given in respect thereof, or (ii) subject only to termination of Pledgor’s obligations hereunder in accordance with the terms of Section 14.10, any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Pledgor in respect of the Obligations or this Agreement. The Pledgor waives any and all notices of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by the Pledgee upon this Agreement, and the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Agreement, and all dealings between the Company and the Pledgee shall likewise be conclusively presumed to have been had or consummated in reliance upon this Agreement.

7

(b) irrevocably makes, constitutes and appoints the Pledgee (and all officers, employees or agents designated by the Pledgee) as the Pledgor’s true and lawful agent and attorney-in-fact, with full authority in the place and stead of the Pledgor and in the name of the Pledgor, the Pledgee or otherwise, from time to time in the Pledgee’s discretion after the occurrence and during the continuance of an Event of Default, to take any action and to execute any instrument that the Pledgee may deem reasonably necessary or advisable to accomplish the purposes of this Agreement, including the following:

(1) to take or cause to be taken all actions necessary to perform or comply or cause performance or compliance with the terms of this Agreement, including to pay or discharge taxes or encumbrances levied or placed upon or threatened against the Pledged Collateral, the legality or validity thereof and the amounts necessary to discharge the same to be determined by the Pledgee in its sole discretion, any such payments made by the Pledgee to become Obligations of the Pledgor to the Pledgee, due and payable immediately and without demand;

(2) to exercise all voting and other rights in respect of the Pledged Collateral;

(3) to receive, endorse, assign, collect and deliver any and all notes, acceptances, checks, drafts, money orders or other instruments, documents or other evidences of payment relating to the Pledged Collateral;

(4) to ask for, demand, collect, ▇▇▇ for, recover, compound, receive payment of, give receipt for and give discharges and releases of all or any of the Pledged Collateral;

(5) to commence and prosecute any and all suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect or otherwise realize on all or any of the Pledged Collateral or to enforce any rights in respect of any Pledged Collateral and/or to settle, compromise, compound, adjust or defend any claims, actions, suits or proceedings relating to all or any of the Pledged Collateral; to use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with all or any of the Pledged Collateral; and

(6) generally to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Pledged Collateral as fully and completely as though Pledgee were the absolute owner thereof for all purposes, and to do, at the Pledgee’s option and the Pledgor’s expense, at any time or from time to time, all acts and things that the Pledgee reasonably deems necessary to protect, preserve or realize upon the Pledged Collateral and the Pledgee’s security interest therein in order to effect the intent of this Agreement, all as fully and effectively as the Pledgor might do.

8

SECTION 8. Voting Rights; Distributions.

(a) Notwithstanding anything in this Agreement to the contrary, unless and until an Event of Default shall have occurred and be continuing, the Pledgor shall have the full right to vote the Pledged Interests in its sole and absolute discretion at any annual or special meeting, as the case may be, of the equity holders of the Company for a purpose not inconsistent with the terms of this Agreement (including Section 5(f)) or any other Finance Document; provided, however, that if an Event of Default has occurred and is continuing the Pledgee shall have the exclusive right (but not the obligation) to vote the Pledged Interests at its own discretion at any annual or special meeting, as the case may be, of the equity holders of the Company by using the Proxy in the form attached as Exhibit C hereto or otherwise and, to facilitate the exercise of such exclusive right, the Pledgor shall promptly execute and deliver (or cause to be executed and delivered) to the Pledgee all proxies and other instruments as the Pledgee may from time to time reasonably request. For the avoidance of doubt, the Pledgee shall have no liability for any vote, proxy or instrument delivered by it at the request of the Pledgor.

(b) All Distributions shall be distributed at the direction of the Pledgor, which direction shall be in accordance with the Amended and Restated Loan Agreement. If any Event of Default shall have occurred and is continuing and, if the Pledgee shall so request, the Pledgor agrees to execute and deliver to the Pledgee appropriate dividend and other orders and documents directing that all Distributions be paid to the Pledgee. Any Distribution received by the Pledgor contrary to the provisions of this Section 8(b) shall be received in trust for the benefit of the Pledgee, shall be segregated from other funds of the Pledgor and shall be forthwith paid over to the Pledgee as Pledged Collateral in the same form as so received (with any necessary endorsement).

SECTION 9. Dispositions of Collateral by Pledgor; Release of Pledgee’s Lien. The Pledgor shall not sell, transfer or otherwise dispose of Pledged Collateral except as permitted by the Finance Documents.

SECTION 10. UCC Filings. The Pledgor does hereby authorize the Pledgee to do all things the Pledgee may reasonably deem to be necessary or advisable in order to perfect or maintain the security interest granted by this Agreement including, but not limited to, filing any and all Uniform Commercial Code financing statements or renewals, continuations or amendments thereof and, if applicable, analogous documents in respect of the Pledged Collateral in all relevant filing offices in any applicable jurisdiction.

SECTION 11. Remedies. At any time after the occurrence and during the continuance of an Event of Default, the Pledgee shall be entitled, without further notice to the Pledgor, in addition to all other rights and remedies available to it at law or in equity:

(a) subject to the limitations of Sections 9-610 and 9-615 of the UCC (to the extent applicable), to sell, assign, transfer and deliver at any time the whole, or from time to time any part, of the Pledged Collateral or any rights or interests therein, at public or private sale or in any other manner, at any of the Pledgee’s offices or elsewhere, at such price or prices and on such terms as the Pledgee may deem appropriate, and either for cash,

9

on credit, for other property or for future delivery, at the option of the Pledgee, upon such other terms as the Pledgee may deem appropriate, and upon not less than 10 days’ written notice (which 10 day notice is hereby acknowledged by the Pledgor to be reasonable) addressed to the Pledgor at its last address provided to the Pledgee pursuant to this Agreement, but without demand, advertisement or other notice of any kind (all of which are hereby expressly waived by the Pledgor); provided that (i) the Pledgee will be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to persons who will represent and agree that they are purchasing the Pledged Collateral for their own account for investment and not with a view to the distribution or sale thereof, and (ii) upon consummation of any such sale the Pledgee will have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Pledged Collateral so sold. The Pledgee will not be obligated to make any sale of any Pledged Collateral if it determines not to do so, regardless of the fact that notice of sale of such Pledged Collateral may have been given. Furthermore:

(i) If any of the Pledged Collateral or any rights or interests thereon are to be disposed of at a public sale, the Pledgee may, without notice or publication, adjourn any such sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, occur at the time and place identified in such announcement.

(ii) If any of the Pledged Collateral or any rights or interests therein shall be disposed of at a private sale, the Pledgee shall be relieved from all liability or claim for inadequacy of price so long as such sale was otherwise conducted in a commercially reasonable manner; in furtherance of the foregoing the Pledgor hereby waives any claims against the Pledgee arising by reason of the fact that the price at which any Pledged Collateral may have been sold at such private sale was less than the price that might have been obtained at a public sale, even if the Pledgee accepts the first offer received and does not offer such Pledged Collateral to more than one offeree so long as such sale was otherwise conducted in a commercially reasonable manner.

(iii) At any such sale the Pledgee or any Lender may purchase the whole or any part of the Pledged Collateral or any rights or interests therein so sold and the Pledgee will be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Pledged Collateral sold at any such public sale, to use and apply any of the Obligations as a credit on account of the purchase price for any Pledged Collateral payable by the Pledgee at such sale.

(iv) Each purchaser, including the Pledgee should it acquire the Pledged Collateral, at any public or private sale shall hold the property sold free from any claim or right of the Pledgor, including the right of redemption, stay, valuation, appraisal or reclamation on the part of the Pledgor which are hereby expressly waived and released to the extent permitted by applicable law. If any of the Pledged Collateral or any rights or interests therein shall be sold on credit or for future delivery, the Pledged Collateral or rights or interests so sold may be

10

retained by the Pledgee until the selling price thereof shall be paid by the purchaser, but the Pledgee shall not incur any liability in case of failure of the purchaser to take up and pay for the Pledged Collateral or rights or interests therein so sold. In case of any such failure, such Pledged Collateral or rights or interests therein may again be sold on not less than 10 days’ written notice as aforesaid.

(v) For purposes hereof, a written agreement to purchase the Pledged Collateral or any portion thereof will be treated as a sale thereof; the Pledgee will be free to carry out such sale pursuant to such agreement and the Pledgor will not be entitled to the return of the Pledged Collateral or any portion thereof subject thereto, notwithstanding the fact that after the Pledgee has entered into such an agreement all Events of Default have been remedied and the Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, the Pledgee may proceed by a suit or suits at law or in equity to foreclose upon the Pledged Collateral and to sell the Pledged Collateral or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver.

(vi) If the Proceeds of any sale or other disposition of the Pledged Collateral are insufficient to pay the entire outstanding amount of the Obligations, the Pledgor will be liable for the deficiency and any reasonable fees of any attorneys employed by the Pledgee to collect such deficiency. The Pledgor further agrees that a breach of any of the covenants contained in this Section 11(a) will cause irreparable injury to the Pledgee, that the Pledgee has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 11(a) will be specifically enforceable against the Pledgor, and the Pledgor hereby waives and agrees not to assert any defenses in an action for specific performance of such covenants except for a defense that no default has occurred giving rise to the Obligations becoming due and payable prior to their stated maturities. Nothing in this Section will in any way alter the rights of the Pledgee hereunder, and the Pledgee will have no obligation to marshal any of the Pledged Collateral.

(b) Subject to Section 8, to exercise all voting and other equity interest rights at any meeting of the Company and exercise any and all rights of conversion, exchange, subscription or any other rights, privileges or options pertaining to the Pledged Interests of the Company as if it were the absolute owner thereof, including, without limitation, the right to exchange at its discretion, such Pledged Interests upon the merger, consolidation, reorganization, recapitalization or other readjustment of the Company or, upon the exercise by the Company or the Pledgee of any right, privilege or option pertaining to such Pledged Interest, and in connection therewith, to deposit and deliver such Pledged Interests with any committee, depository, transfer agent, registrar or other designated agency upon such terms and conditions as it may determine, all without liability except to account for property actually received by it; and

11

(c) in light of the restrictions and limitations relating to certain Pledged Collateral under the U.S. federal securities laws and otherwise, the Pledgee, in its sole and absolute discretion exercised in good faith, (i) may proceed to make a sale of the Pledged Collateral whether or not a registration statement for the purpose of registering such Pledged Collateral or part thereof has been filed under the U.S. federal securities laws and (ii) may approach and negotiate with a single potential purchaser to effect such sale. The Pledgor acknowledges and agrees that (A) compliance with the U.S. federal securities laws might very strictly limit the course of conduct of the Pledgee, if the Pledgee were to attempt to dispose of all or any part of the Pledged Collateral, and might also limit the extent to which or the manner in which any subsequent transferee of any Pledged Collateral could dispose of the same, (B) there may be other legal restrictions or limitations affecting the Pledgee in any attempt to dispose of all or part of the Pledged Collateral under applicable blue sky laws or other state securities laws or similar laws analogous in purpose or effect, (C) in light of such restrictions and limitations, the Pledgee may, with respect to any sale of the Pledged Collateral, limit the purchasers to those who will agree, among other things, to acquire such Pledged Collateral for their own account, for investment, and not with a view to the distribution or resale thereof, and (D) any such sale might result in prices and other terms less favorable to the seller than if such sale were a public sale without such restrictions. In the event of any such sale, the Pledgee will incur no responsibility or liability for selling all or any part of the Pledged Collateral at a price that the Pledgee, in its sole and absolute discretion, may in good ▇▇▇▇▇ ▇▇▇▇ reasonable under the circumstances, notwithstanding the possibility that a substantially higher price might have been realized if the sale were deferred until after registration as aforesaid or if more than a single purchaser were approached. The provisions of this clause (c) will apply notwithstanding the existence of a public or private market upon which the quotations or sales prices might exceed substantially the price at which the Pledgee sells.

SECTION 12. No Duty on Pledgee; Standard of Care.

(a) Notwithstanding any other provision of this Agreement, nothing herein contained will be construed as requiring or obligating the Pledgee to make any inquiry as to the nature or sufficiency of any payment received by it, or to present or file any claim or notice, or to take any action with respect to the Pledged Collateral or any part thereof or the moneys due or to become due in respect thereof or any property covered thereby, and no action taken or omitted to be taken by the Pledgee with respect to the Pledged Collateral or any part thereof will give rise to any defense, counterclaim or offset in favor of the Pledgor or to any claim or action against the Pledgee. It is understood and agreed that the appointment of the Pledgee as the agent and attorney-in-fact of the Pledgor in Section 7(b) is coupled with an interest and is irrevocable. The provisions of this Section 12 will in no event relieve the Pledgor of any of its obligations hereunder or under the Guarantee with respect to the Pledged Collateral or any part thereof or impose any obligation on the Pledgee to exercise any of the rights, privileges or options contained in this Agreement or any other Finance Document, or in any way limit the exercise by the Pledgee of any other or further right that it may have on the date of this Agreement or hereafter, whether hereunder, under any other Finance Document, by law or otherwise. The Pledgee shall not be responsible for any failure to do so or delay in so doing and will be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents will be responsible to the Pledgor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

12

(b) Except for the exercise of reasonable care in the custody of any Pledged Collateral in its possession and the accounting for moneys actually received by it hereunder, the Pledgee will have no duty as to any Pledged Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Pledged Collateral. The Pledgee will be deemed to have exercised reasonable care in the custody and preservation of Pledged Collateral in its possession if such Pledged Collateral is accorded treatment substantially equal to that which the Pledgee accords its own property. Neither the Pledgee nor any of its directors, officers, employees or agents will be liable for failure to demand, collect or realize upon all or any part of the Pledged Collateral or for any delay in doing so or will be under any obligation to sell or otherwise dispose of any Pledged Collateral upon the request of the Pledgor or otherwise. If the Pledgor fails to perform any agreement contained herein, the Pledgee may itself perform, or cause performance of, such agreement, and the expenses of the Pledgee incurred in connection therewith will be payable by the Pledgor in accordance with the Finance Documents.

SECTION 13. Application of Proceeds. All moneys collected or received by the Pledgee pursuant to this Agreement shall be applied as provided in the Clause 9.7 of the Amended and Restated Loan Agreement.

SECTION 14. Miscellaneous.

(i) execute, acknowledge, deliver and cause to be duly filed all such further instruments, documents, endorsements, powers of attorney or notices, and take all such actions as may be necessary or desirable, or as the Pledgee may from time to time reasonably request, to preserve, protect and perfect the security interest and the rights and remedies created hereby, including the payment of any fees and taxes required in connection with the execution and delivery of this Agreement, the granting of the security interest and the filing of any financing statements or other documents in connection herewith or therewith; and
