annual or periodic basis, such as the deduction for depreciation, shall be apportioned to the period prior to and including the Closing Date ratably on a per diem basis). Notwithstanding anything to the contrary herein, any franchise Tax paid or payable with respect to SemCrude Pipeline or White Cliffs Pipeline shall be allocated to the taxable period during which the income, operations, assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another taxable period is obtained by the payment of such franchise Tax.

Anything to the contrary in this Agreement notwithstanding, the representations, warranties, covenants, agreements, rights and obligations of the Parties with respect to any Tax matter covered by this Agreement shall survive the Closing and shall not terminate until thirty (30) days after the expiration of the applicable statutes of limitations (including all periods of extension and tolling) applicable to such Tax matter.

7.6 Conflict.

In the event of a conflict between the provisions of this Article VII and any other provisions of this Agreement, the provisions of this Article VII shall control.

7.7 Tax Characterization of Transaction.

Immediately prior to the Closing, the Partnership shall borrow approximately $133.5 million under the Revolving Credit Agreement to fund a portion of the Cash Consideration (the “Partnership Debt”). The Parties intend that the Contributing Parties will be treated as receiving a distribution from the Partnership at Closing: (a) first out of the proceeds of the Partnership Debt as a “debt-financed transfer” within the meaning of Treasury Regulations Section 1.707-5(b)(1) to the extent of the Contributing Parties’ allocable share of the indebtedness incurred under the Partnership Debt under Treasury Regulations Sections 1.707-5(a)(2) and 1.752-3(a)(3); (b) to the extent the amount distributed to the Contributing Parties exceeds the Contributing Parties’ allocable share of the indebtedness incurred under the Partnership Debt as described in clause (a), as a reimbursement of the Contributing Parties’ preformation expenditures with respect to the Subject Interest within the meaning of Treasury Regulations Section 1.707-4(d), to the extent applicable; and (c) to the extent the amount distributed exceeds the amounts described in clauses (a) and (b), in a transaction subject to treatment under Section 707(a)(2)(B) of the Code and the Treasury Regulations thereunder as in part a sale, and in part a contribution, of the Subject Interest to the Partnership to the extent that Treasury Regulations Sections 1.707-4(d) and 1.707-5(b)(1) are inapplicable.

(b) The indemnification obligations under this Article IX or elsewhere in this Agreement shall apply regardless of whether any suit or action results solely or in part from the active, passive or concurrent negligence or strict liability of the indemnified party.

9.5 Demands.

(a) Each indemnified party hereunder agrees that promptly upon its discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by it of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise, by any third party (such claims for indemnity involving third party claims being collectively referred to herein as the “Indemnity Claim”), with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, it will give prompt notice thereof in writing to the indemnifying party (a “Claim Notice”), together with a detailed statement of such information respecting any of the foregoing as it shall have and all supporting evidence,

including any Damages already incurred and its detailed estimate of any Damages to be incurred in the future. Such notice shall include a formal demand for indemnification under this Agreement.

(b) If the indemnified party knowingly failed to notify the indemnifying party thereof in accordance with the provisions of this Agreement in sufficient time to permit the indemnifying party or its counsel to defend against an Indemnity Claim and to make a timely response thereto, the indemnifying party’s indemnity obligation relating to such Indemnity Claim shall be limited to the extent that such failure has actually prejudiced or damaged the indemnifying party with respect to that Indemnity Claim.

(c) With respect to any claim for indemnification not involving an Indemnity Claim, the indemnifying party shall be deemed to have agreed to indemnify the indemnified party pursuant to this Article IX with respect to the claims set forth in any Claim Notice if and to the extent the indemnifying party does not provide the indemnified party notice of its disagreement with respect to the contents of a Claim Notice within thirty (30) calendar days of receipt thereof.

9.6 Right to Contest and Defend.

(a) The indemnifying party shall be entitled, at its cost and expense, to contest and defend by all appropriate legal proceedings any Indemnity Claim for which it is called upon to indemnify by the indemnified party under the provisions of this Agreement; provided, that notice of the intention to so contest shall be delivered by the indemnifying party to the indemnified party within twenty (20) days from the date of receipt by the indemnifying party of notice by the indemnified party of the assertion of the Indemnity Claim. Any such contest may be conducted in the name and on behalf of the indemnifying party or the indemnified party as may be appropriate. Such contest shall be conducted by reputable counsel employed by the indemnifying party and not reasonably objected to by the indemnified party, but the indemnified party shall have the right but not the obligation to participate in such proceedings and to be represented by counsel of its own choosing at its sole cost and expense.

(b) The indemnifying party shall have full authority to determine all action to be taken with respect thereto; provided, however, that the indemnifying party will not have the authority to subject the indemnified party to any obligation whatsoever, other than the performance of purely ministerial tasks or obligations not involving material expense or injunctive relief. If the indemnifying party does not elect to contest any such Indemnity Claim, the indemnifying party shall be bound by the result obtained with respect thereto by the indemnified party. If the indemnifying party assumes the defense of an Indemnity Claim, the indemnified party shall agree to any settlement, compromise or discharge of an Indemnity Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Indemnity Claim, which releases the indemnified party completely in connection with such Indemnity Claim and which would not otherwise adversely affect the indemnified party as reasonably determined by the indemnified party.

(c) Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Indemnity Claim (and shall be liable for the reasonable fees and

expenses of counsel incurred by the indemnified party in defending such Indemnity Claim) if the Indemnity Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the indemnified party which the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Indemnity Claim can be so separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages.

9.7 Cooperation.

If requested by the indemnifying party, the indemnified party agrees to cooperate with the indemnifying party and its counsel in contesting any Indemnity Claim that the indemnifying party elects to contest or, if appropriate, in making any counterclaim against the Person asserting the Indemnity Claim, or any cross-complaint against any Person, and the indemnifying party will reimburse the indemnified party for any expenses incurred by it in so cooperating without regard to any limitations set forth in Section 9.10. At no cost or expense to the indemnified party, the indemnifying party shall cooperate with the indemnified party and its counsel in contesting any Indemnity Claim.

9.8 Right to Participate.

The indemnified party agrees to afford the indemnifying party and its counsel the opportunity to be present at, and to participate in, conferences with all Persons, including Governmental Authorities, asserting any Indemnity Claim against the indemnified party or conferences with representatives of or counsel for such Persons.

9.9 Payment of Damages.

The indemnification required hereunder shall be made by periodic payments of the amount thereof during the course of the investigation or defense, within ten (10) days as and when reasonably specific bills are received or Damages are incurred and reasonable evidence thereof is delivered. In calculating any amount to be paid by an indemnifying party by reason of the provisions of this Agreement, the amount shall be reduced by all insurance proceeds received and any indemnification reimbursement proceeds received from third parties.

9.10 Limitations on Indemnification.

(a) To the extent that the Partnership Indemnified Parties are entitled to indemnification for Damages pursuant to Section 9.1(a) or Section 9.1(b), the Contributing Parties shall not be liable for such Damages until the aggregate amount of all such Damages exceeds 1.0% of the dollar value of the Aggregate Consideration as of the Closing Date (the “Threshold Amount”), and then, subject to the following sentence, the Contributing Parties shall be liable for all such Damages, whether incurred before or after the Threshold Amount was exceeded. In no event shall the Contributing Parties’ aggregate liability to the Partnership Indemnified Parties under Section 9.1(a) exceed 15.0% of the dollar value of the Aggregate Consideration as of the Closing Date (the “Ceiling Amount”). Notwithstanding the foregoing, (i) the Threshold Amount shall not apply to inaccuracies, violations or breaches of

representations and warranties contained in Sections 3.1, 3.2, 3.4 and 3.17 (collectively, the “Contributing Parties Fundamental Representations”) and (ii) the Ceiling Amount shall not apply to inaccuracies, violations or breaches of any of the Contributing Parties Fundamental Representations, provided the Contributing Parties’ aggregate liability for a breach of the Contributing Parties Fundamental Representations shall not exceed an amount equal to the dollar value of the Aggregate Consideration as of the Closing Date.

(b) To the extent the Contributing Indemnified Parties are entitled to indemnification for Damages pursuant to Section 9.2(a) or Section 9.2(b), the Partnership Parties shall not be liable for such Damages until the aggregate amount of all such Damages exceeds the Threshold Amount, and then, subject to the following sentence, the Contributing Parties shall be liable for all such Damages, whether incurred before or after the Threshold Amount was exceeded. In no event shall the Partnership Parties’ aggregate liability to the Contributing Indemnified Parties under Section 9.2(a) exceed the Ceiling Amount. Notwithstanding the foregoing, (i) the Threshold Amount shall not apply to inaccuracies, violations or breaches of representations and warranties contained in Sections 4.1, 4.2, 4.4 and 4.6 (the “Partnership Fundamental Representations”) and (ii) the Ceiling Amount shall not apply to inaccuracies, violations or breaches of any of the Partnership Fundamental Representations, provided the Partnership Parties’ aggregate liability for a breach of the Partnership Fundamental Representations shall not exceed an amount equal to the dollar value of the Aggregate Consideration as of the Closing Date.

(d) The Parties agree that any indemnification or payment obligation of the Contributing Parties under Section 9.1(a) (to the extent relating to any inaccuracy, violation or breach of a representation or warranty in Sections 3.1(b), 3.1(c), 3.4(b) or 3.4(c) or in Sections 3.5 through 3.16) relating to Damages suffered or incurred by the Partnership Indemnified Parties, attributable to SemCrude Pipeline or White Cliffs Pipeline or their respective assets, businesses or operations, shall be limited to Damages actually suffered or incurred by the Partnership Indemnified Parties. For purposes of illustration (and without limiting the generality of the foregoing), in the event any Damages are suffered or incurred by SemCrude Pipeline or White Cliffs Pipeline, the Damages suffered or incurred by the Partnership Parties would be 33.33% and 17% thereof, respectively.

9.11 Sole Remedy.

Should the Closing occur, no Party shall have any liability under this Agreement, any of the Ancillary Documents or the transactions contemplated hereby or thereby except as is provided in Article VII or this Article IX (other than claims or causes of action arising from actual fraud).

10.5 Entire Agreement; Amendments and Waivers.

(a) This Agreement and the Ancillary Documents constitute the entire agreement among the Parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof.

(b) No supplement, modification or waiver of this Agreement shall be binding unless executed in writing by each Party to be bound thereby. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided.

This Agreement and the other Ancillary Documents, read as a whole, set forth the Parties’ rights, responsibilities and liabilities with respect to the transactions contemplated by this Agreement. In the Agreement and the Ancillary Documents, and as between them, specific provisions prevail over general provisions. In the event of a conflict between this Agreement and the Ancillary Documents, this Agreement shall control.

10.7 Binding Effect; Assignment; Parties in Interest.

This Agreement shall be binding upon and inure to the benefit of the Parties and their respective permitted successors and assigns, but neither this Agreement nor any of the rights, benefits or obligations hereunder shall be assigned or transferred, by operation of law or otherwise, by any Party hereto without the prior written consent of each other Party. Notwithstanding anything in this Section 10.7, any Party may (without seeking the consent of the other Parties) transfer or otherwise alienate any of its rights, title, interest or obligations under this Agreement in connection with (a) a transfer to an Affiliate which remains an Affiliate, (b) the granting of a pledge, mortgage, hypothecation, Lien or other security interest, (c) the foreclosure (judicial or non-judicial) or other settlement or rearrangement pursuant to or in connection with any transfer made pursuant to (b) above, (d) a transfer in connection with the sale of all or substantially all of the assets of such Party, if applicable, or (e) a merger, consolidation, share exchange or other form of statutory reorganization with another Person if such Party is the sole surviving Person.

WHEREAS, Section 13.1(d)(i) of the Partnership Agreement provides that the General Partner, without the approval of any Partner, may amend any provision of the Partnership Agreement to reflect a change that the General Partner determines does not adversely affect the Limited Partners considered as a whole (or any particular class of Partnership Interests as compared to other classes of Partnership Interests) in any material respect; and

WHEREAS, the Partnership has entered into a Contribution Agreement, dated January 8, 2013, by and among the Partnership, the General Partner, SemGroup Corporation, Rose Rock Midstream Holdings, LLC, a Delaware limited liability company (“Holdings”), and Rose Rock Midstream Operating, LLC, a Delaware limited liability company, pursuant to which, among other things, (i) Holdings will assign and convey a 33.33% member interest in SemCrude Pipeline, L.L.C., a Delaware limited liability company, which owns a 51.00% member interest in White Cliffs Pipeline, L.L.C., a Delaware limited liability company (“White Cliffs”), to the Partnership, and (ii) the Partnership will issue to Holdings Class A Units representing a new class of Partnership Interests to be designated as “Class A Units,” with such terms as are set forth in this Amendment; and

WHEREAS, the General Partner has determined, that the amendments to the Partnership Agreement set forth herein (i) do not adversely affect the Limited Partners considered as a whole in any material respect and (ii) are necessary or appropriate in connection with the creation, authorization and issuance of the Class A Units;

NOW, THEREFORE, the General Partner does hereby amend the Partnership Agreement as follows:

Section 1. AMENDMENTS.

(a) Section 1.1. Section 1.1 is hereby amended to add or to amend and restate, as applicable, the following definitions:

“Class A Conversion Effective Date” means the first day of the month immediately following the first month for which average daily throughput volumes on the White Cliffs Pipeline for such month are 125 mbpd or greater (the “Class A Conversion Effective Date”).

“Class A Unit” means a Partnership Interest representing a fractional part of the Partnership Interests of all Limited Partners, and having the rights and obligations specified with respect to Class A Units in this Agreement. The term “Class A Unit” does not refer to a Common Unit.

“Common Unit” means a Partnership Interest representing a fractional part of the Partnership Interests of all Limited Partners, and having the rights and obligations specified with respect to Common Units in this Agreement. The term “Common Unit” does not include a Subordinated Unit or a Class A Unit prior to its conversion into a Common Unit pursuant to the terms hereof.

“Holdings” has the meaning assigned to such term in the recitals to Amendment No. 1 to the Partnership Agreement.

“Limited Partner Interest” means the ownership interest of a Limited Partner in the Partnership, which may be evidenced by Common Units, Subordinated Units, Incentive Distribution Rights, Class A Units or other Partnership Interests or a combination thereof or interest therein, and includes any and all rights and benefits to which such Limited Partner is entitled as provided in this Agreement, together with all obligations of such Limited Partner to comply with the terms and provisions of this Agreement; provided, however, that when the term “Limited Partner Interest” is used herein in the context of any vote or other approval, including Article XIII and Article XIV, such term shall not, solely for such purpose, include any Incentive Distribution Right except as may be required by law.

“mbpd” means thousand barrels per day.

“Unit” means a Partnership Interest that is designated as a “Unit” and shall include Common Units, Subordinated Units and Class A Units but shall not include (a) Notional General Partner Units (or the General Partner Interest represented thereby) or (b) Incentive Distribution Rights.

“White Cliffs” has the meaning assigned to such term in the recitals to Amendment No. 1 to the Partnership Agreement.

“White Cliffs Pipeline” means the interstate pipeline that transports crude oil from Platteville, Colorado to Cushing, Oklahoma owned by White Cliffs.

(b) Article IV; Section 4.8(c). Article IV of the Partnership Agreement is hereby amended to add the following sentence to the end of Section 4.8(c):

“(c) The transfer of a Common Unit that was issued upon conversion of a Class A Unit shall be subject to the restrictions imposed by Section 6.10.”

(c) Article V; Section 5.5(c). Section 5.5(c) of the Partnership Agreement is hereby amended to add a new Section 5.5(c)(iv) as follows:

“(iv) Subject to Section 6.10, immediately prior to the transfer of a Class A Unit or of a Common Unit that was issued upon conversion of a Class A Unit pursuant to Section 5.12(f) by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this Section 5.5(c)(iv) apply), (A) first, the Capital Account maintained for such Person with respect to its Class A Units or Common Units issued upon conversion of Class A Units will be allocated to the Class A Units or Common Units issued upon conversion of Class A Units to be transferred in an amount equal to the product of (x) the number of such Class A Units or Common Units issued upon conversion of Class A Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any Class A Units or Common Units issued upon conversion of Class A Units (“Retained Converted Class A Units”). Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained Class A Units or Retained Converted Class A Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee’s Capital Account established with respect to the transferred Class A Units or Common Units issued upon conversion of Class A Units will have a balance equal to the amount allocated under clause (A) hereinabove.”

(d) Article V; Section 5.12. Article V of the Partnership Agreement is hereby amended to add a new Section 5.12 creating a new series of Partnership Interests as follows:

“Section 5.12 Establishment of Class A Units.

(a) General. The General Partner hereby designates and creates a class of Partnership Interest to be designated as “Class A Units” and consisting of a total of 1,250,000 Class A Units, and fixes the designations, preferences and relative, participating, optional or other special rights, powers and duties of holders of the Class A Units as set forth in this Section 5.12.

(b) Rights of Class A Units. During the period commencing upon issuance of the Class A Units and ending on the Class A Conversion Effective Date:

(i) Allocations. Except as otherwise provided in this Agreement, all items of Partnership income, gain, loss, deduction and credit, including Unrealized Gain or Unrealized Loss to be allocated to Partners pursuant to Section 6.1(c), shall be allocated to the Class A Units to the same extent as such items would be so allocated if such Class A Units were Common Units that were then Outstanding.

(ii) Distributions. Prior to the Class A Conversion Effective Date, the Class A Units shall not be entitled to receive distributions of Available Cash pursuant to Section 6.3.

(c) Voting Rights. Prior to the Class A Conversion Effective Date, the Class A Units shall be entitled to vote with the Common Units as a single class on any matters on which Unitholders are entitled to vote, except that the Class A Units shall be entitled to vote as a separate class on any matter that adversely affects the rights or preferences of the Class A Units in relation to other classes of Partnership Interests (including as a result of a merger or consolidation) or as required by law. The approval of a majority of the Class A Units shall be required to approve any matter for which the holders of the Class A Units are entitled to vote as a separate class. Each Class A Unit will be entitled to the number of votes equal to the number of Common Units into which a Class A Unit is convertible at the time of the Record Date for the vote or written consent on the matter.

(d) Certificates. The Class A Units will be evidenced by certificates in substantially the form of Exhibit A to Amendment No. 1 to this Agreement and, subject to Section 6.10 and the satisfaction of any applicable legal and regulatory requirements, may be assigned or transferred in a manner identical to the assignment and transfer of Common Units. The certificates will initially include a restrictive legend to the effect that the Class A Units have not been registered under the Securities Act or any state securities laws.

(e) Registrar and Transfer Agent. The General Partner will act as registrar and transfer agent of the Class A Units.

(f) Conversion. Each Class A Unit shall automatically convert into one Common Unit (subject to appropriate adjustment pursuant to Section 5.9 in the event of any split-up, combination or similar event affecting the Common Units or other Units that occurs prior to the Class A Conversion Effective Date) on the Class A Conversion Effective Date without any further action by the holders thereof. The terms of the Class A Units will be changed, automatically and without further action, on the Class A Conversion Effective Date so that each Class A Unit is converted into one Common Unit and, immediately thereafter, none of the Class A Units shall be Outstanding; provided, however, that such converted Class A Units will remain subject to the provisions of Sections 6.1(d)(xiv) and 6.10.

(g) Surrender of Certificates. Subject to the requirements of Section 6.10, on or after the Class A Conversion Effective Date, each holder of Class A Units shall promptly surrender the Class A Unit Certificates therefor, duly endorsed, at the office of the General Partner or of any transfer agent for the Class A Units. In the case of any such conversion, the Partnership shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Class A Units one or more Common Unit Certificates, registered in the name of such holder, or other evidence of the issuance of uncertificated certificates, for the number of Common Units to which such holder shall be entitled. Such conversion shall be deemed to have been made as of the Class A Conversion Effective Date whether or not the Class A Unit Certificate has been surrendered as of such date, and the Person entitled to receive the Common Units issuable upon such conversion shall be treated for all purposes as the record holder of such Common Units as of such date.

(e) Article VI; Section 6.1(d)(iii)(A). Section 6.1(d)(iii)(A) of the Partnership Agreement is hereby amended and restated to read in its entirety:

“(A) If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 12.4) with respect to a Unit exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Unit (except a Class A Unit with respect to any Record Date prior to the Class A Conversion Effective Date) (the amount of the excess, an “Excess Distribution” and the Unit with respect to which the greater distribution is paid, an “Excess Distribution Unit”), then (1) there shall be allocated gross income and gain to each Unitholder receiving an Excess Distribution with respect to the Excess Distribution Unit until the aggregate amount of such items allocated with respect to such Excess Distribution Unit pursuant to this Section 6.1(d)(iii)(A) for the current taxable period and all previous taxable periods is equal to the amount of the Excess Distribution; and (2) the General Partner shall be allocated gross income and gain with respect to each such Excess Distribution in an amount equal to the product obtained by multiplying (aa) the quotient determined by dividing (x) the General Partner’s Percentage Interest at the time when the Excess Distribution occurs by (y) a percentage equal to 100% less the General Partner’s Percentage Interest at the time when the Excess Distribution occurs, times (bb) the total amount allocated in clause (1) above with respect to such Excess Distribution.

(f) Article VI; Section 6.1(d)(xiv). Section 6.1(d) is hereby amended to add a new Section 6.1(d)(xiv) as follows:

“(xiv) Class A Economic Uniformity. With respect to any taxable period in which the Class A Conversion Effective Date occurs (and, if necessary, any subsequent taxable period), items of Partnership gross income, gain, deduction or loss for the taxable period shall be allocated 100% to each Limited Partner with respect to such Limited Partner’s Class A Units that are Outstanding immediately before the Class A Conversion Effective Date in the proportion that the respective number of Class A Units held by such Partner bears to the total number of Class A Units then Outstanding, until each such Partner has been allocated the amount of gross income, gain, deduction or loss with respect to such Partner’s Class A Units that causes the Capital Account attributable to each Class A Unit, on a per Unit basis, to equal the Per Unit Capital Amount for a Common Unit on the Class A Conversion Effective Date. The purpose for this allocation is to establish uniformity between the Capital Accounts underlying converted Class A Units and the Capital Accounts underlying Common Units immediately prior to the conversion of Class A Units into Common Units.

(g) Article VI; Section 6.10. Article VI is hereby amended to add a new Section 6.10 as follows:

“Section 6.10 Special Provisions Relating to the Holders of Class A Units. A Unitholder holding a Common Unit issued upon conversion of a Class A Unit pursuant to Section 5.12 shall not be issued a Common Unit Certificate pursuant to Section 4.1, and shall not be permitted to transfer such Common Units until such time as the General Partner determines, based on advice of counsel, that the Common Unit issued upon conversion of such Class A Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.10, the General

Partner shall take whatever steps are required to provide economic uniformity to the Common Units issued upon conversion of Class A Units in preparation for a transfer of such Common Units, including the application of Sections 5.5(c)(iv) and 6.1(d)(xiv); provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units represented by Common Unit Certificates.”

Section 2. RATIFICATION OF PARTNERSHIP AGREEMENT. Except as expressly modified and amended herein, all of the terms and conditions of the Partnership Agreement shall remain in full force and effect.

Section 3. GOVERNING LAW. This Amendment will be governed by and construed in accordance with the laws of the State of Delaware.

IN WITNESS WHEREOF, the General Partner has executed this Amendment as of the date first written above.
