REGISTRATION RIGHTS AGREEMENT    
  


        THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is entered into as of December 20, 2002, by and among
Brigham Exploration Company, a Delaware corporation (the "Company"), and Shell Capital Inc. ("SCI").  


  
 

    RECITALS    
  


        WHEREAS, pursuant to that certain Exchange Agreement (the "Exchange Agreement") dated as of November 21,
2002 between the Company and SCI, the Company has agreed to issue SCI 550,000 shares of the Company's common stock, par value $.01 per share (the "Common
Stock"); 


        WHEREAS,
in connection with such issuance, the Company and SCI desire to enter into this Agreement in order to grant the registration rights as set forth below. 


 
 

AGREEMENT    
  


        1.    Definitions


        For
purposes of this Agreement, the following terms have the following meanings: 



        (a)  "Form S-3" means such form under the Act as in effect on the date hereof or any registration form
under the Act subsequently adopted by the Securities and Exchange Commission (the "SEC") that similarly permits inclusion or incorporation of
substantial information by reference to other documents filed by the Company with the SEC. 


        (b)  "Holder" means any person owning or having the right to acquire Registrable Securities who is a party to this Agreement
as of the date hereof or who may be added as a party pursuant to the terms of this Agreement and any assignee thereof who meets the requirements set forth in Section 10. 


        (c)  "register,"  "registered" and  "registration" refer to a registration effected by preparing
and filing a registration statement or similar document in compliance with the Securities
Act of 1933, as amended (the "Act"), and the declaration or order of effectiveness of such registration statement or document. 



        (d)  "Registrable Securities" means (i) the 550,000 shares of the Common Stock of the Company to be issued to SCI
pursuant to the Exchange Agreement and (ii) any Common Stock of the Company issued as (or issuable upon the conversion or exercise of any warrant, right or other security which is issued as) a
dividend or other distribution with respect to, or in exchange for or in replacement of, such Common Stock, excluding in all cases, however, any Registrable Securities sold by a person in a
transaction in which its rights under this Agreement are not assigned. For the purposes of this Agreement, a Registrable Security ceases to constitute a Registrable Security hereunder (i) when
such Registrable Security shall have been effectively registered under the Securities Act and disposed of in a public market transaction pursuant to a Registration Statement, (ii) when such
Registrable Security shall have been sold pursuant to Rule 144 (or any successor provision) under the Securities Act, (iii) when such Registrable Security shall have been otherwise
transferred and a new certificate for such Registrable Security not bearing a legend restricting further transfer shall have been delivered by the Company, (iv) with respect to a particular
Holder, at any time when all of such Holder's remaining Registrable Securities can be sold in a single transaction in compliance with Rule 144 under the Securities Act, or (v) when such
Registrable Security shall have ceased to be outstanding. 


        (e)  "Registrable Securities then outstanding" means the number of shares of Common Stock outstanding which are Registrable
Securities. 


        (f)    "SEC" means the Securities and Exchange Commission. 






 





        2.    Request for Registration    



        (a)  If
the Company shall receive a written request from the Holders of at least 50% of the Registrable Securities then outstanding (the "Initiating
Holders") that the Company file a registration statement under the Act covering the registration of at least 250,000 of the Registrable Securities (a  "Demand
Registration"), then the Company shall, within 10 days after the receipt of the Demand Registration, give written notice of such request
to all Holders (the "Company Notice") and shall, subject to the limitations set forth below, use its reasonable best efforts to effect as soon as
practicable the registration under the Act of all Registrable Securities that the Holders request to be registered in a written request to be given within 30 days of receipt of the Company
Notice. The Company Notice shall include reasonable details relating to the proposed registration and the due date for replies. 


        (b)  The
Company is obligated to effect only one registration pursuant to this Section 2. 


        (c)  Notwithstanding
the foregoing, if the Company shall furnish to the Initiating Holders requesting a registration pursuant to this Section 2 within 30 days
of receiving the Demand Registration a certificate signed by the President of the Company stating that in the good faith Judgment of the Board of Directors of the Company it would be seriously
detrimental to the Company and its stockholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, the Company shall have the
right to defer such filing for up to 2 periods of not more than 45 days each after receipt of the Demand Registration; provided, however, that the Company may not use this right more than once
(for a total of up to 90 days) in any 12-month period; and provided, further that the Company shall promptly notify the Initiating Holders requesting a registration pursuant to this
Section 2 of any decision by the Company to abandon or indefinitely delay such public offering. During any such delay the Initiating Holders may withdraw the Demand Registration and the
consequence of such withdrawal is that the Company's obligation under Section 2(b) hereof is not satisfied. 




        3.    Company Registration


        If
the Company proposes to register (including for this purpose a registration effected by the Company for stockholders ("Requesting
Holders") other than the Holders) any of its stock or other securities under the Act in connection with the public offering of such securities solely for cash (other than a
registration relating solely to the sale of securities to participants in a Company stock plan, or a registration on any form that does not include substantially the same information as would be
required to be included in a registration statement covering the sale of Registrable Securities), the Company shall, at each such time, promptly give each Holder written notice of such registration.
Upon the written request of each such Holder given within 20 days after receipt of such notice by such Holder from the Company, the Company shall, subject to the provisions of the following
sentence, use its reasonable best efforts to cause to be registered under the Act all of the Registrable Securities that each such Holder has requested to be registered. If the managing underwriter of
a proposed public offering shall advise the Company in writing that, in its opinion, the distribution of the Registrable Securities requested to be included in the registration concurrently with the
securities being registered
by the Company or any Requesting Holder would materially and adversely affect the distribution of such securities by the Company or such Requesting Holders, then all selling security holders (but not
the Company or the Requesting Holders) shall reduce the amount of Registrable Securities of each intended to be distributed through such offering on a pro rata basis to the greatest aggregate amount
which, in the opinion of such managing underwriter, would not materially and adversely affect the distribution of such securities. 


        In
the event that the Company decides for any reason not to complete the registration of shares of Common Stock other than Registrable Securities, the Company shall have no obligation
under this Section 3 to continue with the registration of Registrable Securities. Any request pursuant to this 


2





 




Section 3 to register Registrable Securities as part of an underwritten public offering of Common Stock shall specify that such Registrable Securities are to be included in the underwriting on
the same terms and conditions as the shares of Common Stock otherwise being sold through underwriters under such registration. Notwithstanding any provision herein, the rights of all Holders under
this Section 3 are subject to the express limitations contained in the registration rights agreements in effect on the date hereof between the Company and other parties, all of which are on
file with the SEC on the date hereof. 


        4.    Obligations of the Company


        Whenever
required under this Agreement to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 



        (a)  Prepare
and file with the SEC a registration statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration
statement to become effective, and, upon the request of the Holders of 50% of the Registrable Securities registered thereunder, keep such registration statement effective for up to one hundred twenty
(120) days. 


        (b)  Prepare
and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as
may be necessary to comply with the provisions of the Act with respect to the disposition of all securities covered by such registration statement. 


        (c)  Furnish
to the Holders such copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Act and such other documents as they
may reasonably request to facilitate the disposition of all securities covered by such registration statement 


        (d)  Use
commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or blue sky laws of such
jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required to qualify to do business or to file a general consent to service of process in
any such states or jurisdictions. 


        (e)  In
the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing
underwriter(s) of such offering. Each Holder participating in such registration shall also enter into and perform its obligations under such an agreement. 


        (f)    Notify
each Holder of Registrable Securities covered by such registration statement, during the time when a prospectus is required to be delivered under the Act, of the
happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. 


        (g)  At
the request of any Holder selling Registrable Securities in such registration, furnish on the date that such Registrable Securities are delivered to the underwriters
for sale in connection with such registration (i) an opinion, dated such date, of legal counsel representing the Company for the purposes of such registration, in form and substance as is
customarily given by Company counsel to underwriters in an underwritten public offering, addressed to the underwriters and (ii) a letter, dated such date, from the independent certified public
accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters. 


        (h)  List
the Registrable Securities being registered on any national securities exchange on which a class of the Company's equity securities is listed or qualify the
Registrable Securities being 



3





 





registered for inclusion on Nasdaq if the Company does not have a class of equity securities listed on a national securities exchange. 




        5.    Furnish Information


        It
shall be a condition precedent to the obligations of the Company to take any action pursuant to this Agreement that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be reasonably required to effect the registration of their Registrable
Securities and shall execute such documents in connection with such registration as the Company may reasonably request. 


        6.    Expenses of Registration


        In
connection with any registration pursuant to this Agreement, the Company shall be responsible for the payment of all reasonable expenses of the registration, with the exception of
(i) underwriting discounts and commissions, which shall be paid by the Company, the Holders and any other selling ho lders of the Company's securities in proportion to the aggregate value of
the securities offered for sale by each of them, (ii) the fees and expenses of counsel to the selling Holders The expenses to be paid by the Company shall include, without limitatio n, all
registration, filing and qualification fees, printing and accounting fees, and the fees and disbursements of counsel for the Company; provided, however, that the Company shall not be required to pay
for any expenses of any registration proceeding begun pursuant to Section 2 if the registration request is subsequently withdrawn (other than a withdrawal due to a material adverse change in
the Company's business or financial condition or pursuant to the last sentence of Section 2(c)), unless, in the eve nt of a registration initiated pursuant to the provisions of
Section 2, the Holders of all of the Registrable Securities agree to forfeit the right to one demand registration. 


        7.    Delay of Registration


        No
Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any registration of the Company as the result of any controversy that might arise with
respect to the interpretation or implementation of this Agreement. 


        8.    Indemnification


        In
the event any Registrable Securities are included in a registration statement under this Agreement: 



        (a)  To
the extent permitted by law, the Company will indemnify and hold harmless each Holder, any underwriter (as defined in the Act) for such Holder and each person, if
any, who controls such Holder or underwriter within the meaning of the Act or the Securities Exchange Act of 1934, as amended (the "1934 Act"), against
any actual expenses (including legal fees and costs), losses, claims, damages (including settlement amounts) or liabilities joint or several) (collectively,  "Losses") to which they may become
subject under the Act, the 1934 Act or other federal or state law, insofar as such Losses arise out of or are based
upon any of the following statements, omissions or violations (collectively, a "Violation") relating to or in connections with the Registration
Statement: (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained
therein, or any amendments or supplements thereto, untrue in light of the circumstances under which they were made, (ii) the omission or alleged omission to state therein a material fact
required to be stated therein, or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (iii) any violation or alleged violation
by the Company of the Act, the 1934 Act, any state securities law
or any rule or regulation promulgated under the Act, the 1934 Act or any state securities law. The Company will 



4





 


reimburse (as incurred) each such Holder, underwriter or controlling person for any Losses reasonably incurred by them in connection with investigating or defending any Violations; provided, however,
that the indemnity agreement contained in this Section 8(a) shall not apply to amounts paid in settlement of any claims for Violations if such settlement is made without the consent of the
Company, which consent shall not be unreasonably withheld, nor shall the Company be liable in any such case for any Losses that arise out of or are based upon a Violation that occurs in reliance upon
and in conformity with written information furnished expressly for use in connection with such registration by, or on behalf of, any such Holder, underwriter or controlling person. 


        (b)  To
the extent permitted by law, each selling Holder will indemnify and hold harmless the Company and its officers, directors, agents and employees, each underwriter and
each other Holder selling securities in such in registration statement, and any person who controls any of the foregoing within the meaning of the Act or the 1934 Act, against any Losses to which the
Company or such officer, director, agent, employee, or underwriter or other selling Holder or controlling person may become subject under the Act, the 1934 Act or other federal or state law, insofar
as such Losses arise out of or are based upon any Violation that occurs in reliance upon and in conformity with written information furnished by, or on behalf of, such Holder expressly for use in
connection with such registration; and each such Holder will reimburse any Losses reasonably incurred by the Company or its officers, directors, agents, employees, or underwriters or other selling
Holders or controlling persons in connection with investigating or defending any Violations; provided, however, that (i) the indemnity agreement contained in this Section 8(b) shall not
apply to amounts paid in settlement of any claims for Violations if such settlement is made without the consent of the Holder, which consent shall not be unreasonably withheld and (ii) the
obligations of such Holders shall be limited to an amount equal to the gross proceeds before expenses and commissions to each such Holder of Registrable Securities sold as contemplated herein. 



        (c)  Promptly
after receipt of notice of the commencement of any action (including any governmental action), an indemnified party will, if a claim is to be made against any
indemnifying party under this Section 8, deliver to the indemnifying party a written notice of the commencement, and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying party similarly notified to assume the defense thereof with counsel mutually satisfactory to the parties; provided,
however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying Party, if, in the opinion of counsel for the indemnifying
party, representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party
and any other party represented by such counsel in the proceeding. The failure to deliver written notice to the indemnifying party within a reasonable period of time after notice of the commencement
of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 8 to the extent such failure is prejudicial to its ability to defend such
action, but the omission to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 8. 



        (d)  If
the indemnification provided for in this Section 8 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any
Losses, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such
proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the Violations that resulted in such
Losses as well as any other relevant equitable considerations; provided, that, in no event shall any 



5





 





contribution by a Holder under this Section 8(d) exceed the gross proceeds before expenses and commissions to each such Holder, except in the case of willful fraud by such Holder. The relative
fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the Violation resulting in such Losses relates to information supplied by
the indemnifying party or by the indemnifying party and the parties' relative intent, knowledge, access to information, and opportunity to correct or prevent such Violation. 



        (e)  Notwithstanding
the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection
with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. 


        (f)    The
obligations of the Company and Holders under this Section 8 shall survive the completion of any offering of Registrable Securities and the termination of
Registration Rights pursuant to Sectio n 12. 




        9.    Reports Under the Act


        With
a view to making available to the Holders the benefits of SEC Rule 144 promulgated under the Act and any other rule or regulation of the SEC that may at an time permit a
Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to use commercially reasonable efforts to: 



        (a)  Make
and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the first
registration statement filed by the Company for the offering of its securities to the general public; 


        (b)  File
with the SEC in a timely manner all reports and other documents required of the Company under the Act and the 1934 Act; and 


        (c)  Furnish
to any Holder, so long as the Holder owns any Registrable Securities, promptly upon request (i) a written statement by the Company that it has complied
with the reporting requirements of the 1934 Act (at any time after the date on which it becomes subject to such reporting requirements), or that it qualifies as a registrant whose securities may be
resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents
so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such
securities without registration or pursuant to such Form S-3. 




        10.  Assignment of Registration Rights


        The
rights to cause the Company to register Registrable Securities pursuant to this Agreement may be assigned by a Holder to a transferee or assignee of such securities who shall, upon
such transfer or assignment, be deemed a "Holder" under this Agreement; provided that the Company is, within a reasonable period of time after such transfer, furnished with written notice of the name
and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; provided, further, that such assignment shall be effective only if
immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Act and that such transferee or assignee is (a) an entity
controlling, controlled by or under common control with any Holder that is not an individual or (b) a transferee or assignee that after the transfer or assignment holds at least
one-third of the Registrable Securities or 175,000 of the Registrable Securities, whichever is greater. 


6





 



        11.  "Market Standoff" Agreement


        The
Holders hereby agree that they shall not, to the extent requested by the Company and an underwriter of Common Stock (or other securities) of the Company, sell or otherwise transfer
or dispose (other than to transferees who agree to be similarly bound) of any Registrable Securities for 180 days following the effective date of a registration statement of the Company filed
under the Act; provided, however, that the foregoing shall not be effective unless all officers and directors of the Company (whether or not pursuant to this Agreement) enter into similar agreements
and the Company has used all reasonable efforts to obtain similar agreements from all holders of at least 1% of the Company's then outstanding Common Stock. 


        To
enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities of the Holders (and the shares or securities
of every other person subject to the foregoing restriction) until the end of such period. 


        12.  Termination of Registration Rights


        The
registration rights granted under Sections 2, 3 and 4 of this Agreement shall terminate as to each Holder on the third (3rd) anniversary of the date of this Agreement. 


        13.  Miscellaneous



        13.1 Notices




        Any
notice required or permitted under this Agreement shall be given in writing and shall be deemed effectively given (a) upon personal delivery to the party to be notified,
(b) upon confirmation of receipt by fax by the party to be notified, (c) one business day after deposit with a reputable overnight courier, prepaid for overnight delivery and addressed
as set forth in (d), or (d) three days after deposit with the United States Post Office, postage prepaid, registered or certified with return receipt requested and addressed to the party to be

foregoing manner. 


        13.2 Amendments and Waivers


        Any
term of this Agreement may be amended and the observance of any term may be waived (either generally or in a particular instance and either retroactively or prospectively) only with
the written consent of the Company and the holders of a majority of the Registrable Securities then outstanding; provided that no amendment may have the effect of excluding any Holder from
participating in any registratio n covered hereby or grant additional rights to any Holder that are not granted to all Holders, unless the Holder adversely affected has executed the amendment.
Additional Holders may be added to this Agreement with such consent by amending Schedule A and adding a signature page executed by such
additional Holder. 


        13.3 Governing Law; Jurisdiction; Venue


        This
Agreement shall be governed by and construed under the laws of the State of New York without regard to principles of conflict of laws. The parties irrevocably consent to the
jurisdiction and venue of the state and federal courts located in New York City in connection with any action relating to this Agreement. 


        13.4 Successors and Assigns


        The
terms and conditions of this Agreement shall inure to the benefit of and be binding on the respective successors and assigns of the parties as provided herein.

        13.5.Severability


        If
one or more provisions of this Agreement are held to be-unenforceable under applicable law, such provision shall be excluded from this Agreement, and the balance of this
Agreement shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms. 


        13.6 Entire Agreement; Counterparts

Agreement constitutes the entire agreement between the parties about its subject and supersedes all prior agreements. This Agreement may be executed in two or more counterparts,
which together shall constitute one instrument.
