shares of Common Stock at a price per share of $2.0525 for an aggregate purchase

thereof to purchase one fully paid and nonassessable share of Common Stock of
the Company at the exercise price of $2.565625, subject to adjustment in certain
circumstances. The Warrants may be exercised immediately in whole or in part, at

              SECURITIES PURCHASE AND REGISTRATION RIGHTS AGREEMENT

                                    Recitals:

         (a) This SECURITIES PURCHASE AND REGISTRATION RIGHTS AGREEMENT (this
"Agreement") is dated as of February 22, 2000, by and among GAP Coinvestment
Partners II, L.P., Special Situations Private Equity Fund, L.P., and Aspect
Resources, L.L.C. (each individually, a "Buyer," and collectively, the "Buyers")
and Brigham Exploration Company, a Delaware corporation (the "Company"); and

         (b) The Company desires to issue to Buyers, and Buyers desire to
purchase, shares of the Company's common stock, par value $.01 per share and
warrants affording the right to purchase shares of the Company's common stock.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, and intending to be legally bound hereby, the Company and
Buyers hereby agree as follows:

                                   ARTICLE I.

                            TERMS OF THE TRANSACTION

         1.1 Agreement to Issue Shares. Within five (5) business days of
Closing, and on the terms and subject to the conditions set forth in this
Agreement, the Company shall have issued to each Buyer, and each Buyer
(severally) shall purchase and accept from the Company, the number of shares of
common stock of the Company (the "Common Stock") as set forth beside its name on
Schedule I (as issued to all Buyers, collectively, the "Shares"); provided,
however, that in the case of Aspect and Special Situations, the Company shall
issue each such Buyer's shares concurrent with its delivery of such Buyer's
share of the Purchase Price to the Company, which shall occur within thirty (30)
days after Closing.

         1.2 Agreement to Issue Warrants . Within five (5) business days of
Closing, and on the terms and subject to the conditions set forth in this
Agreement, the Company shall issue and deliver to each Buyer the number of
warrants to purchase common stock of the Company as set forth beside its name on
Schedule I hereto (as issued to all Buyers, collectively, the "Warrants");
provided, however, that in the case of Aspect and Special Situations, the
Company shall issue such Buyer's warrants concurrent with such Buyer's delivery
of its share of the Purchase Price to the Company, which shall occur within
thirty (30) days after Closing.

         1.3 Purchase Price and Payment. In consideration of the sale of the
Shares and the Warrants, contemporaneously with its receipt of its portion of
the Shares and Warrants, each Buyer shall pay to the Company, the purchase price
set forth beside its name on Schedule I, the aggregate of which shall be the
"Purchase Price", the Purchase Price per Share (the "Issuance Price") was
determined by reference to the greater of (a) $2.05, and (b) the minimum Average
Price per Share necessary to prevent triggering antidilution provisions in any
agreement in existence as of the date hereof. Each Buyer shall pay its portion
of the Purchase Price to the Company in immediately available funds by confirmed
wire transfer to a bank account to be designated by the Company. Special
Situations and Aspect shall have a period of thirty (30) days after the Closing
Date to fund their respective allocable


                                       1
<PAGE>

shares of the Purchase Price; if Aspect fails to so timely fund its share of the
Purchase Price, Special Situations shall have no obligation to do so and this
Agreement shall automatically, unless Special Situations nonetheless voluntarily
funds its share of the Purchase Price within such 30-day period, have no further
force and effect relative to Special Situations. Nothing in this Section 1.3 or
elsewhere in this Agreement shall be construed to change or diminish Aspect's
absolute obligation to fund its share of the Purchase Price within 30 days after
the Closing Date.

         1.4 Limitations. The rights and interests afforded Buyers hereunder
and/or under the Warrant Certificate are subject to any pre-existing rights of
the Company's common stock, option and warrant holders.

                                   ARTICLE II.

                                     CLOSING

date as the parties hereto shall agree. The date on which the Closing is

                                   ARTICLE IV.

                    REPRESENTATIONS AND WARRANTIES OF BUYERS

         Each Buyer, only with respect to itself, represents and warrants to the
Company that:

         4.1 Organization and Formation. Each corporate Buyer is duly organized,
validly existing, and in good standing under the laws of the jurisdiction of its
incorporation and has all requisite corporate power and corporate authority to
own, lease, and operate its properties and to carry on its business as now being
conducted. Each partnership Buyer is duly formed and is in good standing (as
applicable) under the laws of the jurisdiction of its formation. No actions or
proceedings to dissolve any Buyer are pending or, to the best knowledge of
Buyers, threatened.

         4.2 Authority Relative to This Agreement. Each Buyer has full power and
authority to execute, deliver, and perform this Agreement and the Ancillary
Documents to which it is a party and to consummate the transactions contemplated
hereby and thereby. The execution, delivery, and performance by Buyers of this
Agreement and the Ancillary Documents to which they are parties, and the
consummation by them of the transactions contemplated hereby and thereby, have
been duly authorized by all necessary corporate or partnership action, as
applicable, of Buyers. This Agreement has been duly executed and delivered by
Buyers and constitutes, and each Ancillary Document executed or to be executed
by Buyers has been, or when executed will be, duly executed and delivered by
each Buyer and constitute, or when executed and delivered will constitute, valid
and legally binding obligations of each Buyer, enforceable against each Buyer in
accordance with their respective terms, except that such enforceability may be
limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium,
and similar laws affecting creditors' rights generally and (ii) equitable
principles which may limit the availability of certain equitable remedies (such
as specific performance) in certain instances.

         4.3 Financing. Each Buyer has, and at the Closing will have, such funds
as are necessary for the consummation by it of the transactions contemplated
hereby.

         4.4 Disclosure of Information. Buyers represent that they have had an
opportunity to ask questions of and receive answers from the Company regarding
the Company and its business, assets, results of operation, and financial
condition and the terms and conditions of the issuance of the Shares. Each Buyer
further represents that it has access to all filings duly made by the Company


                                       4
<PAGE>

with the Securities and Exchange Commission.

         4.5 Investment Experience. Each Buyer acknowledges that it can bear the
economic risk of its investment in the Shares, and has such knowledge and
experience in financial and business matters that it is capable of evaluating
the merits and risks of an investment in the Shares.

         4.6 Restricted Securities. Each Buyer understands that the Shares will
not have been registered pursuant to the Securities Act or any applicable state
securities laws, that the Shares will be characterized as "restricted
securities" under federal securities laws, and that under such laws and
applicable regulations the Shares cannot be sold or otherwise disposed of
without registration under the Securities Act or an exemption therefrom. In this
connection, each Buyer represents that it is familiar with Rule 144 promulgated
under the Securities Act, as currently in effect, and understands the resale
limitations imposed thereby and by the Securities Act. Appropriate stop transfer
instructions may be issued to the transfer agent for securities of the Company
(or a notation may be made in the appropriate records of the Company) in
connection with the Shares.

         4.7 Accredited Investor; Investment Intent. Each Buyer is an accredited
investor as defined in Regulation D under the Securities Act. Each Buyer is
acquiring its portion of the Shares for its own account for investment and not
with a view to, or for sale or other disposition in connection with, any
distribution of all or any part thereof, except in compliance with applicable
federal and state securities laws.

         4.8 Representations and Warranties on Closing Date. The representations
and warranties made in this Article IV will be true and correct in all material
respects on and as of the Closing Date with the same force and effect as if such
representations and warranties had been made on and as of the Closing Date,
except that any such representations and warranties which expressly relate only
to an earlier date shall be true and correct on the Closing Date as of such
earlier date.

<PAGE>

limited by the fact that the act, omission, occurrence, or other state of facts

subject matter of any other representation, warranty, covenant, or agreement
contained in this Agreement (or in any other agreement between the parties) as
to which there is no inaccuracy or breach.

                                   ARTICLE IX

              RESTRICTIONS ON TRANSFERABILITY; REGISTRATION RIGHTS

         9.1 Transfers.

         (a) General. The Shares and the Warrants shall not be transferred
before satisfaction of the conditions specified in this Article IX, which
conditions are intended to reflect the intent of the Company and Buyers and
further to ensure compliance with the provisions of the Securities Act and
applicable state securities laws. Each Buyer, by entering into this Agreement
and accepting the Shares and the Warrants, agrees to be bound by the provisions
of this Article IX.

         (b) Restrictive Legend. Except as otherwise provided in this Article
IX, each certificate representing Warrants, Shares or Warrant Shares shall be
stamped or otherwise imprinted with a legend in substantially the following
form:

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY
         APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD OR TRANSFERRED IN
         THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM. SUCH
         SECURITIES ARE SUBJECT TO THE RESTRICTIONS AND PRIVILEGES SPECIFIED IN
         A SECURITIES PURCHASE AND REGISTRATION RIGHTS AGREEMENT, DATED AS OF
         February 22, 2000, BETWEEN BRIGHAM EXPLORATION COMPANY AND THE INITIAL
         HOLDERS OF SECURITIES NAMED THEREIN, A COPY OF WHICH IS ON FILE WITH
         THE SECRETARY OF BRIGHAM EXPLORATION COMPANY AND WILL BE FURNISHED
         WITHOUT CHARGE TO THE HOLDER HEREOF UPON WRITTEN REQUEST, AND THE
         HOLDER OF THIS CERTIFICATE AGREES TO BE BOUND THEREBY."

         9.2 Registration. The Company shall utilize reasonable best efforts to,
within 90 days after the Closing Date, register on a Form S-3 (or Form S-1 or
successor form to either) Registration Statement all of the Registrable
Securities that are held by any Buyer(s) that, on or before the Closing Date,
have elected to have their Registrable Securities so registered. The Company
shall use its reasonable best efforts to keep such Registration Statement
effective until the twenty-four (24) month anniversary of such Effective Date.

         9.3 Incidental Registration.

         If the Company at any time proposes to file on its behalf and/or on
behalf of any of its


                                       10
<PAGE>

security holders (the "Demanding Security Holders") a Registration Statement
under the Securities Act on any form (other than a Registration Statement (i)
filed pursuant to demand under the Company's Registration Rights Agreement with
Joint Energy Development Investments II Limited Partnership, a Delaware limited
partnership, and Enron Capital & Trade Resources Corp., a Delaware corporation,
dated August 20, 1998, as amended, or (ii) on Form S-8 or any similar or
successor form or any other registration statement relating to an offering of
securities solely to the Company's existing security holders or employees) to
register the offer and sale of its common stock for cash, it will give written
notice to all Buyers at least five (5) days before the anticipated date of
initial filing with the Commission of such Registration Statement, which notice
shall set forth the Company's intention to effect such a registration, the class
or series and number of equity securities proposed to be registered and the
intended method of disposition of the securities proposed to be registered by
the Issuer. The notice shall offer to include in such filing all of each Buyer's
Registrable Securities.

         Each Buyer desiring to have Registrable Securities registered under
this Section 9.3 shall advise the Company in writing within fifteen (15) days
after the date of receipt of such offer from the Company, setting forth the
amount of such Registrable Securities for which registration is requested. The
Company shall thereupon include in such filing the number of Registrable
Securities for which registration is so requested, subject to the next sentence,
and shall use its best efforts to effect registration under the Securities Act
of such securities. 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 the
Demanding Security Holder, as the case may be, would materially and adversely
affect the distribution of such securities by the Company or such Demanding
Security Holders, as the case may be, then all selling security holders (but not
the Company or such Demanding Security Holders, as the case may be) shall reduce
the amount of securities each intended to distribute 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.

         Nothing in this Section 9.3 shall preclude the Company from
discontinuing the registration of its securities being effected on its behalf
under this Section 9.3 at any time prior to the effective date of the
registration relating thereto. Notwithstanding any provision herein, the rights
of the Buyers under this Section 9.3 are subject to the express limitations
contained in registration rights agreements (and registration rights provisions
in agreements) in effect on the date hereof between the Company and other
parties.

         9.4 Requests for Registration. Each Buyer agrees that it will not sell,
transfer or otherwise dispose of any Registrable Securities in whole or part,
except pursuant to an effective Registration Statement under the Securities Act
or an exemption from registration thereunder. Each certificate, if any,
evidencing such Registrable Securities issued upon such transfer shall bear the
restrictive legend set forth in Section 9.1, and each Warrant Certificate issued
upon such transfer shall bear the restrictive legend set forth in Section 9.1 of
this Agreement, unless in the opinion of the transferee's or Buyer's reputable
counsel delivered to the Company in connection with such transfer, such legend
is not required in order to ensure compliance with the Securities Act.

         9.5 Registration Procedures. In its efforts to effect registration of
the Registrable Securities pursuant to Section 9.2 or 9.3, above, the Company
will, as expeditiously as possible:

         (a) furnish to the selling security holders such number of copies or a
summary prospectus or other prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other
documents, as such selling security holders may reasonably request;

         (b) use its best efforts to register or qualify the securities covered
by such Registration Statement under such other securities or blue sky laws of
such jurisdictions within the United States as each holder of such securities
shall request (provided, however, the Company shall not be obligated to qualify
as a foreign corporation to do business under the laws of any jurisdiction in
which it is not then qualified or to file any general consent to service or
process), and do such other reasonable acts and things as may be requited of it
to enable such holder to consummate the disposition in such jurisdiction of the
securities covered by such Registration Statement;

         (c) enter into customary agreements (including an underwriting
agreement in customary form) and take such other actions as are reasonably
required in order to expedite or facilitate the disposition of such Shares; and

         (d) otherwise use its best efforts to comply with all applicable rules
and regulations of the Commission, and make available to its security holders,
as soon as reasonably practicable, but not later than 18 months after the
effective date of the Registration Statement, an earnings statement covering the
period of at least 12 months beginning with the first full month after the
effective date of such Registration Statement, which earnings statements shall
satisfy the provisions of Section 11(a) of the Securities Act.

         It shall be a condition precedent to the obligation of the company to
take any action pursuant to this Article IX in respect of the Registrable
Securities which are to be registered at the request of any Buyer that such
Buyer shall refurnish to the Company such information regarding the Registrable
Securities held by such Buyer and the intended method of disposition thereof as
the Company shall reasonably request and as shall be required in connection with
the action taken by the Company.

         9.6 Rights of Others.

         (a) The Company and any party to any existing agreements with the
Company who are entitled to piggy-back registration rights ("Other Holders")
with respect to a Registration Statement filed pursuant to Section 9.2 or 9.3
may include securities of the Company in such Registration Statement.

         (b) Notwithstanding any provision herein, the rights of the Buyers
under this Article IX are subject to the express limitations contained in
registration rights agreements (and registration rights provisions in
agreements) in effect on the date hereof between the Company and other parties.

         9.7 Expenses. All registration and filing fees (including those
incident to filing with the


                                       12
<PAGE>

NASD), incurred in complying with this Article IX (all of such fees shall be
collectively referred to herein as "Registration Expenses"), shall be paid by
the Company; provided, however, the Company shall not be responsible for any
attorneys' fees or discount or commission or cost reimbursement to any
underwriter in respect of the securities sold by such Buyer, or any other
expenses incurred by Buyers in relation to this Agreement, except as set forth
in this Section 9.7.

         9.8 Liquidated Damages. The parties hereto agree that, without
limitation of any other remedies that may be available to Buyers, upon the
failure of the Company to register the shares of Registrable Securities that are
held by Buyers that have elected on or before the Closing Date to have their
Registrable Securities registered, within 180 days of the Closing Date, the
Buyers that have so elected to have their Registrable Securities registered
shall each be entitled to liquidated damages from the Company in an amount equal
to 1% per month of the Purchase Price paid by such Buyer, with the total
liquidated damages payable by the Company to all Buyers together not to exceed
$100,000. The parties agree that the liquidated damages set forth herein are
reasonable and not a penalty because of the difficulty of ascertaining the
actual damages that would be sustained by the Buyers in the event of such a
material breach of this Agreement by the Company.

identical in form to this Warrant Certificate, but evidencing a number of
Warrants equal to the number of Warrants originally represented and surrender of
this Warrant Certificate to the Company at its address set forth in Section 9
and at the request of the holder, the Company will, without expense, at the
option of the holder, issue to the holder in substitution for this Warrant
Certificate one or more warrant certificates in identical form and for an
aggregate number of Warrants equal to the number of Warrants evidenced by this

prior to the Expiration Date, such Warrants expire and the rights of the holder
shall become void and of no effect.

              (c) In lieu of exercise in accordance with Section 1(a) above, the
Warrants represented hereby may be exercised, in whole or in part, by
presentation and surrender at the office of the Company specified herein of this
Warrant Certificate with the "Alternative Election to Exercise", attached hereto
as Exhibit A-1, duly completed and executed. Upon such exercise, the holder
shall be entitled to receive from the Company, for each share of Common Stock
issuable upon exercise of each Warrant being exercised, shares of Common Stock
with a value equal to the amount by which either the Price or, in the event that
the Common Stock is not Publicly Traded, the Fair Market Value (as defined
below) of one share of Common Stock on the date of exercise exceeds the Exercise
Price (the "Appreciation Amount"). If the Common Stock is Publicly Traded on the
date of exercise of Warrants pursuant to this Section 1(c), the Company shall
deliver (or cause its transfer agent to deliver) certificates representing
shares of Common Stock issuable upon such exercise within ten business days
following the date of exercise. For purposes of this subsection, in the event
that the Common Stock is not Publicly Traded, the "Fair Market Value" of the
share of Common Stock shall be established by the Board of Directors of the
Company in its reasonable discretion. If the Common Stock is not Publicly Traded
on the date of exercise of Warrants pursuant to this Section 1(c), such election
may be withdrawn by the holder at any time prior to the third business day
following the date on which the holder receives notice of the final
determination of the Fair Market Value of the share of Common Stock. Unless the
holder timely withdraws its exercise, the Company shall deliver (or cause its
transfer agent to deliver) certificates representing Common Stock so issuable
within 10 business days following the date of determination of the Fair Market
Value. In lieu of any fractional shares otherwise issuable upon exercise
pursuant hereto, the Company shall pay to the holder cash in an amount equal to
the Price, or in the event the Company is not Publicly Traded, the Fair Market
Value of such fractional share.

         2. Antidilution Adjustments. The shares of Common Stock purchasable on
exercise of the Warrants are shares of Common Stock as constituted as of the
Issuance Date. The number and kind of securities purchasable upon the exercise
of the Warrants, and the Exercise Price, shall be subject to adjustment from
time to time upon the happening of certain events, as follows:

              Mergers, Consolidations and Reclassifications. In case of any
reclassification or change of outstanding securities issuable upon exercise of
the Warrants at any time after the Issuance Date (other than a change in par
value, or from par value to no par value or as a result of a subdivision or
combination to which subsection 2(b) applies), or in case of any consolidation
or merger of the Company with or into any entity or other person (other than a
merger with another entity or other person in which the Company is the surviving
corporation and which does not result in any reclassification or change in the
securities issuable upon exercise of this Warrant Certificate), the holder of
the Warrants shall have, and the Company, or such successor corporation or other
entity, shall covenant in the constituent documents effecting any of the
foregoing transactions that such holder does have the right to obtain, upon the
exercise of the Warrants, in lieu of each share of Common Stock, other
securities, money or other property theretofore issuable upon exercise of a
Warrant, the kind and amount of shares of stock, other securities, money or
other property receivable upon such reclassification, change, consolidation or
merger by a holder of the shares of Common Stock, other securities, money or
other property issuable upon exercise of a Warrant if the Warrants had been
exercised immediately prior to such reclassification, change, consolidation


                                    Sch II-3
<PAGE>

or merger. The constituent documents effecting such reclassification, change,
consolidation or merger shall provide for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided in this subsection
2(a). The provisions of this subsection 2(a) shall similarly apply to successive
reclassifications, changes, consolidations or mergers.

              Subdivisions and Combinations. If the Company, at any time after
the Issuance Date, shall subdivide its shares of Common Stock into a greater
number of shares, the Exercise price in effect immediately prior to such
subdivision shall be proportionately reduced, and the number of shares of Common
Stock purchasable upon exercise of the Warrants shall be proportionately
increased, as at the effective date of such subdivision, or if the Company shall
take a record of holders of its Common Stock for such purpose, as at such record
date, whichever is earlier. If the Company, at any time after Issuance Date,
shall combine its shares of Common Stock into a smaller number of shares, the
Exercise Price in effect immediately prior to such combination shall be
proportionately increased, and the number of shares of Common Stock purchasable
upon exercise of the Warrants shall be proportionately reduced, as at the
effective date of such combination, or if the Company shall take a record of
holders of its Common Stock for purposes of such combination, as at such record
date, whichever is earlier.

              Dividends and Distributions. If the Company at any time after the
Issuance Date shall declare a dividend on its Common Stock payable in stock or
other securities of the Company to the holders of its Common Stock, the holder
of this Warrant Certificate shall, without additional cost, be entitled to
receive upon any exercise of a Warrant, in addition to the Common Stock to which
such holder would otherwise be entitled upon exercise, the number of shares of
stock or other securities which such holder would have been entitled to receive
if he had been a holder immediately prior to the record date for such dividend
(or, if no record date shall have been established, the payment date for such
dividend) of the number of shares of Common Stock purchasable on exercise of
such Warrant immediately prior to such record date or payment date, as the case
may be.

              Certain Issuances of Securities. If the Company at any time after
the Issuance Date shall issue any additional shares of Common Stock (otherwise
than as provided in paragraphs (a) through (c) of this Section 2) at a price per
share less than the average Price per share of Common Stock for the 20 trading
days immediately preceding the date of the authorization of such issuance (the
"Market Price") by the Board of Directors, then the Exercise Price upon each
such issuance shall be adjusted to that price determined by multiplying the
Exercise Price by a fraction:

              the numerator of which shall be the sum of (1) the number of
shares of Common Stock outstanding immediately prior to the issuance of such
additional shares of Common Stock multiplied by the Market Price, and (2) the
consideration, if any, received by the Company upon the issuance of such
additional shares of Common Stock, and

              the denominator of which shall be the Market Price multiplied by
the total number of shares of Common Stock outstanding immediately after the
issuance of such additional shares of Common Stock.


                                    Sch II-4
<PAGE>

         No adjustments of the Exercise Price shall be made under this paragraph
(d) upon the issuance of any additional shares of Common Stock that (w) are
issued pursuant to thrift plans, stock purchase plans, stock bonus plans, stock
option plans, employee stock ownership plans, incentive or profit sharing
arrangements for the benefit of employees ("Employee Benefit Plans") that are
approved by the Board of Directors of the Company or its compensation committee
and that otherwise would cause an adjustment under this paragraph (d); provided
that the aggregate number of shares of Common Stock so issued (including the
shares issued pursuant to any options, rights or warrants or convertible or
exchangeable securities issued under such Employee Benefit Plans containing the
right to purchase shares of Common stock) pursuant to Employee Benefit Plans
after the closing date of the IPO, as adjusted for any stock splits, stock
dividends or subdivisions or combinations of Common Stock prior to the
Expiration Date, shall not in the aggregate exceed 10% of the Company's
outstanding Common Stock at the time of such issuance; (x) are issued pursuant
to any Common Stock Equivalent (as hereinafter defined) (i) if upon the issuance
of any such Common Stock Equivalent, any such adjustments shall previously have
been made pursuant to paragraph (e) of the Section 2, (ii) if no adjustment was
required pursuant to paragraph (e) of this Section 2, or (iii) if such Common
Stock Equivalent was issued prior to this Warrant Certificate; or (z) are issued
pursuant to a public offering by the Company.

         Common Stock Equivalents. If the Company shall, after the Issuance
Date, issue any security or evidence of indebtedness which is convertible into
or exchangeable for Common Stock or any ("Convertible Security"), other than
pursuant to Employee Benefit Plans (together with Convertible Securities,
"Common Stock Equivalent "), or if, after any such issuance, the price per Share
for which additional shares of Common Stock may be issuable thereunder is
amended, then the Exercise Price upon each such issuance or amendment shall be
adjusted as provided in subsection (d) on the basis that (i) the maximum number
of additional shares of Common Stock issuable pursuant to all such Common Stock
Equivalents shall be deemed to have been issued as of the earlier of (a) the
date on which the Company shall enter into a firm contract for the issuance of
such Common Stock Equivalent, or (b) the date of actual issuance of such Common
Stock Equivalent; and (ii) the aggregate consideration for such maximum number
of additional shares of Common Stock shall be deemed to be the minimum
consideration received and receivable by the Company for the issuance of such
additional shares of Common Stock pursuant to such Common Stock Equivalent;
provided, however, that no adjustment shall be made pursuant to this subsection
(e) unless the consideration received and receivable by the Company per share of
Common Stock for the issuance of such additional shares of Common Stock pursuant
to such Common Stock Equivalent is less than the Market Price. No adjustment of
the Exercise Price shall be made under this subsection (e) upon the issuance of
any Convertible Security which is issued pursuant to the exercise of any
warrants or other subscription or purchase rights therefor, if any adjustment
shall previously have been made in the Exercise Price then in effect upon the
issuance of such warrants or other rights pursuant to this subsection (e).

         Miscellaneous. The following provisions shall be applicable to the
making of adjustments in the Exercise Price hereinbefore provided in this
Section 2:


                                    Sch II-5
<PAGE>

         The consideration received by the Company shall be deemed to be the
following: (I) to the extent that any additional shares of Common Stock or any
Common Stock Equivalent shall be issued for cash consideration, the
consideration received by the Company therefor, or, if such additional shares of
Common Stock or Common Stock Equivalent are offered by the Company for
subscription, the subscription price, or, if such additional shares of Common
Stock or Common Stock Equivalent are sold to underwriters or dealers for public
offering without a subscription offering, the initial public offering price, in
any such case excluding any amounts paid or receivable for accrued interest or
accrued dividends and without deduction of any compensation, discounts,
commissions or expenses paid or incurred by the Company for and in the
underwriting of , or otherwise in connection with, the issue thereof; (II) to
the extent that such issuance shall be for a consideration other than cash,
then, except as herein otherwise expressly provided, the fair value of such
consideration at the time of such issuance as determined in good faith by the
Board of Directors, as evidenced by a certified resolution of the Board of
Directors delivered to the holder of this Warrant Certificate setting forth such
determination. The consideration for any additional shares of Common Stock
issuable pursuant to any Common Stock Equivalent shall be the consideration
received by the Company for issuing such Common Stock Equivalent, plus the
additional consideration payable to the Company Upon the exercise, conversion or
exchange of such Common Stock or Common Stock Equivalent in payment of
satisfaction of any dividend upon any class of stock other that Common Stock,
the Company shall be deemed to have received for such additional shares of
Common Stock or Common Stock Equivalent (which shall not be deemed to be a
dividend payable in, or other distribution of, Common Stock under subsection (c)
above) consideration equal to the amount of such dividend so paid or satisfied.

         Upon the expiration of the right to convert, exchange or exercise any
Common Stock Equivalent the issuance of which effected an adjustment in the
Exercise Price, if any such Common Stock Equivalent shall not have been
converted, exercised or exchanged, the number of shares of Common Stock deemed
to be issued and outstanding because they were issuable upon conversion,
exchange or exercise of any such Common Stock Equivalent shall no longer be
computed as set forth above, and the Exercise Price shall forthwith be
readjusted and thereafter be the price which it would have been (but reflecting
any other adjustments in the Exercise Price made pursuant to the provisions of
subsection (d) after the issuance of such Common Stock Equivalent) had the
adjustment of the Exercise Price made upon the issuance or sale of such Common
Stock Equivalent been made on the basis of the issuance only of the number of
additional shares of Common Stock actually issued upon exercise, conversion or
exchange of such Common Stock actually so issued shall be deemed to have been
issued and only the consideration actually received by the Company (computed as
in subparagraph (i) of this paragraph (f) shall be deemed to have been received
by the Company.

         The number of shares of Common Stock at any time outstanding shall not
include any shares thereof then directly or indirectly owned or held by or for
the account of the Company or its wholly owned subsidiaries.

         For the purpose of this Section 2, the term "shares of Common Stock"
shall


                                    Sch II-6
<PAGE>

mean shares of (i) the class of stock designated as the Common Stock at the date
hereof or (ii) any other class of stock resulting from successive changes or
reclassifications of such shares consisting solely of changes in par value, or
from par value to no value, or from no par value to par value. If at any time,
because of an adjustment pursuant to subsection (a), the Warrants shall entitle
the holders to purchase any securities other than shares of Common Stock,
thereafter the number of such other securities so purchasable upon exercise of
each Warrant and the Exercise Price of such securities shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the Common Stock contained in this
Section 2.

         Calculation of Exercise Price. The exercise Price in effect from time
to time shall be calculated to four decimal places and rounded to the nearest
thousandth.

         Notice of Adjustments. Whenever the Exercise Price or the number of
shares of Common Stock is required to be adjusted as provided in Section 2, the
Company shall forthwith compute the adjusted Exercise Price or the number of
shares of Common Stock issuable and shall prepare and mail to the holder hereof
a certificate setting forth such adjusted Exercise Price or such number of
shares of Common Stock, showing in reasonable detail the facts upon which the
adjustment is based.

         Voluntary Reduction. (a) The Company may at its option, but shall not
be obligated to, at any time during the term of the Warrants, reduce the then
current Exercise Price by any amount selected by the Board of Directors;
provided that is the Company elects so to reduce the then current Exercise Price
to, such reduction shall be irrevocable during its effective period and remain
in effect for a minimum of 30 days following the date of such election, after
which time the Company may, at its option, reinstate the Exercise Price in
effect prior to such reduction. Whenever the Exercise Price is reduced, the
Company shall mail to the holder a notice of the reduction at least 30 days
before the date the reduced Exercise Price takes effect, stating the reduced
Exercise Price and the period for which such Exercise Price will be in effect.

         The Company may make such decreases in the Exercise Price, in addition
to those required or allowed by this Section 4, as shall be determined by it, as
evidenced by a certified resolution of the Board of Directors delivered to the
holders, to be advisable to avoid or diminish any income tax to the holder
resulting from any dividend or distribution of stock or issuance of rights or
warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes.


                                    Sch II-7

         Notices to Warrant Holders. In the event:

              (a) the Company shall authorize any consideration or merger to
which the Company is a party and for which approval of any stockholders of the
Company is required, or of the conveyance or sale of all or substantially all of
the assets of the Company, or of any reclassification or change if the Common
Stock or other securities issuable upon exercise of the Warrants (other than a
change in par value, or from par value to no par value, or from no par value to
par value or as result of a subdivision or combination), or a tender offer or
exchange offer for shares of Common Stock (or other securities issuable upon the
exercise of the Warrants); or

              (b) the Company shall declare any dividend (or any other
distribution) on the Common Stock or any other class of its capital stock ; or

              (c) the Company shall authorize the granting to the holders of
Common Stock or any other class of its capital stock of rights or warrants to
subscribe for or purchase any shares of any class or series of capital stock or
any other securities convertible into or exchangeable for shares of stock; or

              (d) of the voluntary or involuntary dissolution, liquidation or
winding up of the Company; then the Company shall cause to be sent to the holder
hereof, at least 30 days prior to the applicable record date hereinafter
specified, or promptly in the case of events for which there is no record date,
a written notice stating (x) the date for the determination of the holders of
record of shares of Common Stock (or other securities issuable upon the exercise
of the Warrants) entitled to receive any such dividends other distribution, (y)
the initial expiration date set forth in any tender offer or exchange offer for
shares of Common Stock (or other securities issuable upon the exercise of the
Warrants), or (z) the date on which any of the events specified in subsections
(a)-(d) is expected to become effective or consummated, and the date as of which
it is expected that holders of record of shares of Common Stock (or securities
issuable upon the exercise of the Warrants) shall be entitled to exchange such
shares for securities or other property, if any, deliverable upon any such
event. Failure to give such notice or any defect therein shall not affect the
legality or validity of any such event, or the vote upon any such action.

         6. Reports to Warrant Holders. The Company will cause to be delivered,
by first-class mail, postage prepaid, to holder at such holder's address

         7. Covenants of the Company. The Company covenants and agrees that:

              (a) Until the Expiration Date, the Company shall at all times
reserve and keep available, out of the aggregate of its authorized but unissued
Common Stock (and other securities), for the purpose for enabling it to satisfy
any obligation to issue shares of Common Stock (and other securities) upon the
exercise of the Warrants, the number of shares of Common Stock (and other
securities) issuable upon the exercise of such Warrants.


                                    Sch II-8
<PAGE>

              (b) The Company shall pay all expenses, taxes and other charges
payable in connection with the preparation, issuance and delivery of new warrant
certificates on transfer of the Warrants.

              (c) All Common Stock (and other securities) which may be issued
upon exercise of the Warrants shall upon issuance be validly issued, fully paid,
non-assessable and free from all preemptive rights and all taxes, liens and
charges with respect to the issuance thereof, and will not be subject to any
restrictions on voting or transfer thereof except as set forth in any
stockholders agreement.

              (d) All original issue taxes payable in respect of the issuance of
shares of Common Stock to the registered holder hereof upon the exercise of the
Warrants shall be borne by the Company; provided, that the Company shall not be
required to pay any tax or charge imposed in connection with any transfer
involved in the issuance of any certificates representing shares of Common Stock
(and other securities) in any name other than that of the registered holder
hereof, and in such case the Company shall not be required to issue or deliver
any certificate representing shares of Common Stock (and other securities) until
such tax or other charge has been paid or it has been established to the
Company's satisfaction that no such tax or charge is due.

              (e) As soon as practicable after the receipt from the holder of
this Warrant Certificate of notice of the exercise of a number of warrants
sufficient to require a filing under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 and the rules, regulations and formal interpretations
thereunder, as amended from time to time (the "HSR Act:), but in any event no
later than the 10th business day after receipt of such notice, the Company will
(i) prepare and file with Antitrust Division of the Department of Justice (the
"DOJ") and the Federal Trade Commission (the "FTC") the Notification and Report
Form (accompanied by all documentary attachments contemplated thereby) required
by the HSR Act, (ii) upon request of the holder, request early termination of
the waiting period imposed by the HSR Act, (iii) coordinate and cooperate with

required under the HSR Act, and (v) reimburse the holder for the entire amount
of any filing fee or any other costs and expenses incurred by the holder in
connection therewith (including legal fees), or as required to be paid under the
HSR Act.

         8. No Rights as Stockholder. The holder of the Warrants shall not, by
