agree to execute, acknowledge and deliver all such additional deeds, assignments, bills of sale, conveyances, instruments, notices, releases, acquittances and other documents, and will do all such
other acts and things, all in accordance with applicable law, as may be necessary or appropriate (a) more fully to assure that the applicable Parties own all of the properties, rights, titles,
interests, estates, remedies, powers and privileges granted by this Agreement, or which are intended to be so granted, or (b) more fully and effectively to vest in the applicable Parties and
their respective successors and assigns beneficial and record title to the interests contributed and assigned by this Agreement or intended so to be and to more fully and effectively carry out the

assets contributed to the MLP or its subsidiaries. It is the express intent of the Parties that the MLP or its subsidiaries own all assets necessary to operate the assets that are identified in this
Agreement and in the Registration Statement. To the extent any assets were not identified but are necessary to the operation of assets that were identified, then the intent of the Parties is that all
such unidentified assets are intended to be conveyed to the appropriate members of the Partnership Group. To the extent such assets are identified at a later date, the Parties shall take the
appropriate actions required in order to convey all such assets to the appropriate members of the Partnership Group. Likewise, to the extent that assets are identified at a later date that were not
intended by the parties to be conveyed as reflected in the Registration Statement, the Parties shall take the appropriate actions required in order to convey all such assets to the appropriate party.

contrary, the Hamm Entities
may engage in the following activities under the following circumstances: 

        (a)   the
ownership and/or operation of the Bakken Gathering System (including replacements of and modifications or additions to the Bakken Gathering System); 

        (b)   any
business that is primarily related to the exploration for and production of oil or natural gas and the sale and marketing of oil and natural gas derived from such
exploration and production activities; 

        (c)   any
Restricted Business that was engaged in by a Hamm Entity on the date of this Agreement; provided, however, that any future acquisitions or opportunities related to
such Restricted Business shall be subject to the procedures set forth in Section 2.3; 

        (d)   the
purchase and ownership of not more than five percent of any class of securities of any entity engaged in the Restricted Business (but without otherwise participating
in the activities of such entity); 

        (e)   any
Restricted Business conducted by a Hamm Entity with the approval of the Conflicts Committee; 

        (f)    the
ownership and/or operation of any asset or group of related assets used in the activities described in Section 2.1 that are acquired or constructed by a Hamm

        (g)   the
ownership and/or operation of any Subject Assets acquired by a Hamm Entity after the Closing Date with a fair market value (as determined in good faith by the board
of directors or other comparable governing body of such Hamm Entity) equal to or greater than $5 million at the time of the acquisition; provided, the Partnership has been offered the

such Hamm Entity shall notify the General Partner, in writing, of such opportunity and deliver to the General Partner all information prepared by or on behalf of such Hamm Entity relating to such
opportunity. As soon as practicable, but in any event within 30 days after 

3

 

receipt
of such written notification and information, the General Partner, on behalf of the Partnership, shall notify the Hamm Entity, in writing, that either (i) the General Partner, on behalf
of the Partnership, has elected (with the concurrence of the Conflicts Committee) not to cause a Partnership Group Member to pursue the opportunity to purchase the Subject Assets, or (ii) the
General Partner, on behalf of the Partnership, has elected (with the concurrence of the Conflicts Committee) to cause a Partnership Group Member to pursue the opportunity to purchase the Subject

governmental approvals to consummate such acquisition have been obtained, and (ii) on terms not more favorable in any material respect to the Hamm Entity than were offered to the Partnership.
If either of these conditions are not satisfied, the opportunity must be reoffered to the Partnership in accordance with this Section 2.3(a). 

        (b)   Notwithstanding
Section 2.3(a), in the event that a Hamm Entity becomes aware of an opportunity to make an acquisition that includes both Subject Assets and
assets that are not Subject Assets and the Subject Assets have a fair market value (as determined in good faith by the board of directors or other comparable governing body of such Hamm Entity) equal
to or greater than $5 million but comprise less than half of the fair market value (as determined in good faith by the board of directors or other comparable governing body of such Hamm Entity)
of the total assets being considered for acquisition, then the Hamm Entity may make such acquisition without first offering the opportunity to the Partnership as long as it complies with the following
procedures: 

        (i)    Within
90 days after the consummation of such an acquisition, the Hamm Entity shall notify the General Partner in writing of such acquisition and offer the
Partnership Group the opportunity to purchase such Subject Assets in accordance with this Section 2.3(b) (the "Offer"). The Offer shall set forth
the terms relating to the purchase of the Subject Assets and, if any Hamm Entity desires to utilize the Subject Assets, the Offer will also include the commercially reasonable terms on which the
Partnership Group will provide services to the Hamm Entity to enable the Hamm Entity to utilize the Subject Assets. As soon as practicable, but in any event within 30 days after receipt of such
written notification, the General Partner shall notify the Hamm Entity in writing that either (x) the General Partner, on behalf of the Partnership, has elected (with the concurrence of the
Conflicts Committee) not to cause a Partnership Group Member to purchase the Subject Assets, in which event the Hamm Entity shall be forever free to continue to own or operate such Subject Assets, or
(y) the General Partner, on behalf of the Partnership, has elected (with the concurrence of the Conflicts Committee) to cause a Partnership Group Member to purchase the Subject Assets, in which
event the following procedures shall apply. 

        (ii)   If
the Hamm Entity and the General Partner (with the concurrence of the Conflicts Committee) within 60 days after receipt by the General Partner of the Offer are
able to agree on the fair market value of the Subject Assets that are subject to the Offer and the other terms of the Offer including, without limitation, the terms, if any, on which the Partnership
Group will provide services to the Hamm Entity to enable it to utilize the Subject Assets, a Partnership Group Member shall purchase the Subject Assets for the agreed upon fair market value as soon as
commercially practicable after such agreement has been reached and, if applicable, enter into an agreement with the Hamm Entity to provide services in a manner consistent with the Offer. 

        (iii)  If
the Hamm Entity and the General Partner (with the concurrence of the Conflicts Committee) are unable to agree within 60 days after receipt by the General
Partner of the Offer on the fair market value of the Subject Assets that are subject to the Offer or the other terms of the Offer including, if applicable, the terms on which the Partnership Group
will provide services to the Hamm Entity to enable it to utilize the Subject Assets, the Hamm Entity and the General Partner will engage a mutually agreed upon investment banking firm to determine the
fair market value of the Subject Assets and/or the other terms on which the General Partner and the Hamm Entity are unable to agree. Such investment banking firm will determine the fair market value
of the Subject Assets and/or the other terms on which the General Partner and the Hamm Entity are unable to agree within 30 days of its engagement and furnish the Hamm Entity and the General
Partner its determination. The fees of the investment banking firm 

4

 

will
be split equally between the Hamm Entity and the Partnership Group. Once the investment banking firm has submitted its determination of the fair market value of the Subject Assets and/or the
other terms on which the Partnership Group and the Hamm Entity are unable to agree, the General Partner will have the right, but not the obligation, subject to the approval of the Conflicts Committee,
to cause a Partnership Group Member to purchase the Subject Assets pursuant to the Offer as modified by the determination of the investment banking firm. The Partnership Group Member will provide
written notice of its decision to the Hamm Entity within 30 days after the investment banking firm has submitted its determination. Failure to provide such notice within such 30-day
period shall be deemed to constitute a decision not to purchase the Subject Assets. If the General Partner elects to cause a Partnership Group Member to purchase the Subject Assets, then the
Partnership Group Member shall purchase the Subject Assets pursuant to the Offer as modified by the determination of the investment banking firm as soon as commercially practicable after such
determination and, if applicable, enter into an agreement with the Hamm Entity to provide services in a manner consistent with the Offer, as modified by the determination of the investment banking
firm, if applicable. 

        (c)   In
the event that a Hamm Entity desires to construct Subject Assets with an estimated Construction Cost (as determined in good faith by the board of directors or other
comparable governing body of such Hamm Entity) equal to or greater than $5 million, then the Hamm Entity may construct such Subject Assets as long as it complies with the following procedures: 

        (i)    Within
90 days after the completion of construction by a Hamm Entity of the Subject Assets, the Hamm Entity shall notify the General Partner in writing of such
construction and offer the Partnership Group the opportunity to purchase such Subject Assets in accordance with this Section 2.3(c) (the "Construction
Offer"). The Construction Offer shall set forth the Hamm Entities' good faith estimate of the actual Construction Cost for the Subject Assets incurred by the Hamm Entities (the
"Actual Construction Cost"), which shall constitute the proposed purchase price for the Subject Assets, together with the other proposed terms relating
to the purchase of the Subject Assets, and, if any Hamm Entity desires to utilize the Subject Assets, the Construction Offer will also include the commercially reasonable terms on which the
Partnership Group will provide services to the Hamm Entity to enable the Hamm Entity to utilize the Subject Assets. As soon as practicable, but in any event within 30 days after receipt of such
written notification, the General Partner shall notify the Hamm Entity in writing that either (x) the General Partner, on behalf of the Partnership, has elected (with the concurrence of the
Conflicts Committee) not to cause a Partnership Group Member to purchase the Subject Assets, in which event the Hamm Entity shall be forever free to continue to own or operate such Subject Assets, or
(y) the General Partner, on behalf of the Partnership, has elected (with the concurrence of the Conflicts Committee) to cause a Partnership Group Member to purchase the Subject Assets, in which
event the following procedures shall apply. 

        (ii)   If
the Hamm Entity and the General Partner (with the concurrence of the Conflicts Committee) within 60 days after receipt by the General Partner of the
Construction Offer are able to agree on the Actual Construction Cost
of the Subject Assets that are subject to the Construction Offer and the other terms ("Other Terms") of the Construction Offer including, without
limitation, the terms, if any, on which the Partnership Group will provide services to the Hamm Entity to enable it to utilize the Subject Assets, a Partnership Group Member shall purchase the Subject
Assets for the agreed upon Actual Construction Cost as soon as commercially practicable after such agreement has been reached and, if applicable, enter into an agreement with the Hamm Entity to
provide services in a manner consistent with the Construction Offer. 

        (iii)  If
the Hamm Entity and the General Partner (with the concurrence of the Conflicts Committee) are unable to agree within 60 days after receipt by the General
Partner of the Construction Offer on the Actual Construction Cost of the Subject Assets that are subject to the Construction Offer, the Hamm Entity and the General Partner will engage a mutually
agreed upon nationally recognized accounting firm, other than any such accounting firm that has served as either Person's independent auditors within the past three years, to determine the Actual
Construction Cost of the Subject Assets. Such accounting firm will determine the Actual Construction Cost of the Subject Assets within 30 days of its engagement and furnish the Hamm Entity and
the General Partner its determination, which determination shall be a final and binding determination of the Actual Construction Cost. The fees of the accounting firm will be split equally between the
Hamm Entity and the Partnership Group. 

5

 

        (iv)  If
the Hamm Entity and the General Partner are unable to agree within 60 days after receipt by the General Partner of the Construction Offer on all of the Other
Terms, the Hamm Entity and the General Partner will obtain a good faith proposal from a mutually agreed upon third party engaged in the business to which such Other Terms relate in order to determine
the Other Terms on which the General Partner and the Hamm Entity are unable to agree. Such third party will submit a good faith proposal regarding the Other Terms on which the General Partner and the
Hamm Entity are unable to agree within 30 days of its engagement and furnish the Hamm Entity and the General Partner its proposal, which determination shall be a final and binding determination
of the Other Terms. The fees of the third party will be split equally between the Hamm Entity and the Partnership Group. 

        (v)   Once
the Actual Construction Cost and the Other Terms have been finally determined pursuant to clauses (ii), (iii) or (iv) above, the General Partner will
have the right, but not the obligation, subject to the approval of the Conflicts Committee, to cause a Partnership Group Member to purchase the Subject Assets pursuant to the Construction Offer as
modified by the determination of the accounting firm and/or the third party submitting a proposal, as applicable. The Partnership Group Member will provide written notice of its decision to the Hamm
Entity within 30 days after the later of the date on which the accounting firm and/or the third party submitting a proposal, as applicable, has submitted its determination. Failure to provide
such notice within such 30-day period shall be deemed to constitute a decision not to purchase the Subject Assets. If the General Partner elects to cause a Partnership Group Member to
purchase the Subject Assets, then the Partnership Group Member shall purchase the Subject Assets pursuant to the Construction Offer as modified by the determination of the accounting firm and/or the
third party submitting a proposal as soon as commercially practicable after such determination and, if applicable, enter into an agreement with the Hamm Entity to provide services in a manner
consistent with the Construction Offer, as modified by the determination of the third party submitting a proposal, if applicable. 

         2.4   Scope of Prohibition.    Except as provided in this Article II and the
Partnership Agreement, each Hamm
Entity shall be free to engage in any business activity, including those that may be in direct competition with any Partnership Group Member. 

        2.5   Enforcement.    Each Hamm Party agrees and acknowledges that the Partnership Group
does not have an adequate
remedy at law for the breach by the Hamm Entities of the covenants and agreements set forth in this Article II, and that any breach by any of the Hamm Entities of the covenants and agreements
set forth in this Article II would result in irreparable injury to the Partnership Group. Each Hamm Party further agrees and acknowledges that any Partnership Group Member may, in addition to
the other remedies which may be available to the Partnership Group, file a suit in equity to enjoin any of the Hamm Entities from such breach, and consents to the issuance of injunctive relief
under this Agreement. 

        2.6   Termination.    This Article II shall terminate on the first to occur of the
following: (i) the
first day on which no Hamm Control Person nor any combination of Hamm Control Persons controls the Partnership, (ii) the death of Harold Hamm and (iii) the fifth anniversary of the date
of this Agreement. 

ARTICLE III

Indemnification  

        3.1   Continental Gas and Hiland Indemnification.    Continental Resources, Hiland and
Continental Holdings shall
jointly and severally indemnify, defend and hold harmless the Partnership Group from and against any losses, damages, liabilities, claims, demands, causes of action, judgments, settlements, fines,
penalties, costs and expenses (including, without limitation, court costs and reasonable attorney's and expert fees) of any and every kind or character, known or unknown, fixed or contingent, suffered
or incurred by the Partnership Group by reason of or arising out of all federal, state and local income tax liabilities attributable to the operation of the Assets prior to the Closing Date, including
any such income tax liabilities that may result from the consummation of the formation transactions contemplated by the Contribution Agreement. 

         3.2   Continental Resources Indemnification.    Continental Resources shall indemnify,
defend and hold harmless the
Partnership Group from and against any losses, damages, liabilities, claims, demands, causes of action, judgments, settlements, fines, penalties, costs and expenses (including, without limitation,
court costs and reasonable attorney's and expert's fees) of any and every kind or character, known or unknown, fixed or contingent, suffered or incurred by the Partnership Group by reason of or
arising out of Continental Gas' 

6

 

ownership,
operation or distribution of the properties and assets (and related rights and obligations) distributed by Continental Gas to Continental Resources in 2004. 

         3.3   Indemnification Procedures.

        (a)   The
Indemnified Party agrees that promptly after it becomes aware of facts giving rise to a claim for indemnification under this Article III, it will provide
notice thereof in writing to the applicable Indemnifying Party, specifying the nature of and specific basis for such claim. 

        (b)   The
Indemnifying Party or Indemnifying Parties shall have the right to control at its sole cost and expense all aspects of the defense of (and any counterclaims with
respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article III, including, without limitation, the selection of counsel,
determination of whether to appeal any decision of any court and the settling of any such matter or any issues relating thereto; provided, however, that
no such settlement shall be entered into without the consent of the Indemnified Party (with the concurrence of the Conflicts Committee) unless it includes a full release of the Indemnified Party from
such matter or issues, as the case may be. 

        (c)   The
Indemnified Party agrees to cooperate fully with each Indemnifying Party, with respect to all aspects of the defense of any claims covered by the indemnification
under this Article III, including, without limitation, the prompt furnishing to each Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may
receive, permitting the name of the Indemnified Party to be utilized in connection with such defense, the making available to each Indemnifying Party of any files, records or other information of the
Indemnified Party that any Indemnifying Party reasonably considers relevant to such defense and the making available to each Indemnifying Party of any employees of the Indemnified Party;  provided, however, that in connection therewith each Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the
operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records, and other information furnished by the Indemnified Party pursuant to this
Section 3.3 In no event shall the obligation of the Indemnified Party to cooperate with each Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon
the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article III;  provided, however, that
the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense.
The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole
control over such defense. 

        (d)   In
determining the amount of any loss, cost, damage or expense for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of
the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and such correlative insurance benefit shall be net of any incremental insurance premiums
that become due and payable by the Indemnified Party as a result of such claim and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons. 

        (e)   The
date on which notification of a claim for indemnification is received by the Indemnifying Party shall determine whether such claim is timely made. 

        (f)    In
no event shall any Indemnified Party be permitted to make any claim under Section 3.2 unless the Indemnified Party provides notice of such claim to the
Indemnifying Party on or before the fifth anniversary of the date of this Agreement. 

ARTICLE IV

General and Administrative Expenses  

        For a period of two years from the Closing Date, Continental Resources shall continue to provide the Partnership Group the general and administrative services
that Continental Resources has provided to Continental Gas and Hiland since January 1, 2004, including but not limited to the general and administrative services listed in Schedule II to
this Agreement (the "Services"). Continental Resources shall exercise at least the same degree of care, skill and prudence in providing the services as
customarily exercised by it for its own operations. In
consideration for the providing of the Services, the Partnership will pay Continental Resources a fee equal to the lesser of (i) Continental Resources' actual cost of providing the Services and
(ii) $50,000, payable annually.

   ARTICLE V

Purchase Option  

         5.1   Option to Purchase the Bakken Gathering System by the Partnership Group.

        (a)   Hiland
hereby grants to the Partnership Group the unconditional right and exclusive option for a period of two years from the Closing Date to purchase for fair market
value at the time of purchase (in accordance with Section 5.2) all of Hiland's right, title and interest in, to and under the Bakken Gathering System. 

        (b)   The
Parties acknowledge that any potential transfer of the Bakken Gathering System pursuant to this Article V is subject to obtaining any and all required written
consents of governmental authorities. 

        (c)   Hiland
hereby (i) represents and warrants that there are no rights of first refusal to purchase the Bakken Gathering System; and (ii) covenants and agrees
that, subject to Section 5.2(c), Hiland will not transfer or grant any right or option to purchase the Bakken Gathering System, other than to a Partnership Group Member, during a period of two
years from the Closing Date. 

         5.2   Procedures.

        (a)   If
a Partnership Group Member decides to exercise the option to purchase the Bakken Gathering System, it will provide written notice to Hiland stating its intention to
exercise the option to purchase the Bakken Gathering System. Within 30 days following receipt of such notice by Hiland, Hiland shall propose to the Partnership Group Member, in writing, a fair
market value for the Bakken Gathering System, taking into account the terms of sale contained herein. The decision to purchase the Bakken Gathering System, the fair market value to be paid for the
Bakken Gathering System and the other terms of the purchase shall be approved by the Conflicts Committee. If the Partnership Group Member and Hiland are unable to agree on the fair market value of the
Bakken Gathering System within 30 days after the Partnership Group Member's receipt of Hiland's proposal, the Partnership Group Member and Hiland will engage a mutually-agreed-upon
investment banking firm to determine the fair market value of the Bakken Gathering System. Such investment banking firm will determine the fair market value of the Bakken Gathering System within
30 days of its engagement and furnish Hiland and the General
Partner its determination. The fees of the investment banking firm will be split equally between Hiland and the Partnership Group. Once the investment banking firm submits its determination of the
fair market value of the Bakken Gathering System, the Partnership Group Member will have the right, but not the obligation, subject to the approval of the Conflicts Committee, to purchase the Bakken
Gathering System on the terms as modified by the determination of the investment banking firm. The Partnership Group Member will provide written notice of its decision to Hiland within 30 days
after the investment banking firm has submitted its determination. Failure to provide such notice within such 30-day period shall be deemed to constitute a decision not to purchase the
Bakken Gathering System. 

        (b)   If
a Partnership Group Member chooses to exercise its option to purchase the Bakken Gathering System under Section 5.2(a), this Agreement shall become a contract
of sale and purchase for the Bakken Gathering System pursuant to which Hiland shall be obligated to sell the Bakken Gathering System to the Partnership Group Member and the Partnership Group Member
shall be obligated to purchase the Bakken Gathering System from Hiland. The terms of the purchase and sale agreement, unless otherwise agreed to by the Partnership Group Member (with the consent of
the Conflicts Committee) and Hiland, will consist of the following: 

        (i)    the
Partnership Group Member will deliver a cash purchase price (unless the Partnership Group Member and Hiland agree that the consideration will be paid by means of
Units or an interest-bearing promissory note); 

        (ii)   Hiland
will represent that it has good and indefeasible title to the Bakken Gathering System, subject to all recorded and unrecorded matters and all physical conditions
and other matters in existence on the closing date for the purchase of the Bakken Gathering System, plus any other such matters as the Partnership Group Member may approve, which approval will not be
unreasonably withheld. If the Partnership Group Member desires to obtain any title insurance with respect to the Bakken Gathering System, the full cost and expense of obtaining the same (including but
not limited to the cost of title examination, document duplication and policy premium) shall be borne by the Partnership Group Member; 

8

 

        (iii)  Hiland
will grant to the Partnership Group Member the right, exercisable at the Partnership Group Member's risk and expense, to make such surveys, tests and
inspections of the Bakken Gathering System as the Partnership Group Member may deem desirable, so long as such surveys, tests or inspections do not damage the Bakken Gathering System or interfere in
any material respect with the activities of Hiland thereon and so long as the Partnership Group Member has furnished Hiland with evidence that adequate liability insurance is in full force and effect; 

        (iv)  the
Partnership Group Member will have the right to terminate its obligation to purchase the Bakken Gathering System under this Section 5.2(b) if Hiland is not
able to make the representations contemplated by Section 5.2(b)(ii) as of the closing date or if the results of any searches, surveys, tests or inspections conducted pursuant to
Section 5.2(b)(ii) or (iii) above are, in the reasonable opinion of the Partnership Group Member, unsatisfactory; 

        (v)   the
closing date for the purchase of the Bakken Gathering System shall occur no later than 90 days following receipt by Hiland of written notice by the
Partnership Group Member of its intention to exercise its option to purchase the Bakken Gathering System pursuant to Section 5.2(a); 

        (vi)  Hiland
shall execute, have acknowledged and deliver to the Partnership Group Member a special warranty deed, assignment of easement, or comparable document, as
appropriate, in the applicable jurisdiction, on the closing date for the purchase of the Bakken Gathering System constituting a real property interest conveying the Bakken Gathering System unto the
Partnership Group Member free and clear of all encumbrances created by Hiland other than those set forth in Section 5.2(b)(ii) above; 

        (vii) the
sale of the Bakken Gathering System shall be made on an "as is," "where is" and "with all faults" basis, and the instruments conveying the Bakken Gathering System
shall contain appropriate disclaimers; 

        (viii) neither
Hiland nor the applicable Partnership Group Member shall have any obligation to sell or buy the Bakken Gathering System if any of the material consents
referred to in Section 5.1(b) have not been obtained; and 

        (ix)  Hiland
and the Partnership Group shall cooperate in good faith and use commercially reasonable efforts to obtain all necessary governmental and other third Person
approvals, waivers and consents required for the closing. Any such closing shall be delayed, to the extent required, until the third Business Day following the expiration of any required waiting
periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. 

        (c)   If
a Partnership Group Member chooses or is deemed to have chosen not to exercise its option to purchase the Bakken Gathering System at the price determined by the
investment banking firm under Section 5.2(a), all future rights to purchase the Bakken Gathering System by the Partnership Group will be extinguished.
