NEITHER THIS WARRANT NOR THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND SUCH
SECURITIES MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED UNLESS SO REGISTERED OR AN
EXEMPTION FROM REGISTRATION UNDER SAID ACT IS AVAILABLE. THIS LEGEND SHALL BE
ENDORSED UPON ANY WARRANT ISSUED IN EXCHANGE FOR THIS WARRANT.


                               WARRANT AGREEMENT

                              FOR COMMON STOCK OF

                               DRKOOP.COM, Inc.


WARRANT NO. 00-02

        THIS CERTIFIES that, for value received, Commonwealth Associates, L.P.
("Commonwealth"), or its permitted assigns (collectively, the "Holder"), is
entitled to purchase from drkoop.com, Inc., a Delaware corporation (the
"Company"), at any time, and from time to time, during the exercise period
referred to in Section 1 hereof 800,000 fully paid, validly issued and
nonassessable shares (the "Warrant Shares") of common stock of the Company, par
value $0.001 (the "Common Stock") at the exercise price of $0.75 per share,
subject to anti-dilution adjustments as provided herein (the "Warrant Share
Price"). Securities issuable upon exercise of this Warrant and the exercise
price payable therefor are subject to adjustment from time to time as
hereinafter set forth. As used herein, the term "Warrant" shall include any
warrant or warrants hereafter issued in consequence of the exercise of this
Warrant in part or transfer of this Warrant in whole or in part.


1.  Exercise; Payment for Ownership Interest.

        (a)  Upon the terms and subject to the conditions set forth herein, this
Warrant may be exercised in whole or in part by the Holder hereof at any time,
or from time to time, on or after the date hereof and prior to 5 p.m. New York
time on June 23, 2007, by presentation and surrender of this Warrant to the
principal offices of the Company, or at the office of its Transfer Agent (as
hereinafter defined), if any, together with the Purchase Form annexed hereto,
duly executed, and accompanied by payment to the Company of an amount equal to
the Warrant Share Price multiplied by the number of Warrant Shares as to which
this Warrant is then being exercised; provided, however, that in each case, the
minimum number of Warrant Shares as to which this Warrant is being exercised
shall not be less than 1,000 Warrant Shares; provided, further, that in the
event
<PAGE>

of any merger, consolidation or sale of all or substantially all the assets of
the Company resulting in any distribution to the Company's stockholders, prior
to June 23, 2007, the Holder shall have the right to exercise this Warrant
commencing at such time through June 23, 2007 into the kind and amount of shares
of stock and other securities and property (including cash) receivable by a
holder of the number of shares of Common Stock into which this Warrant might
have been exercisable immediately prior thereto. Any transfer of Warrant Shares
obtained by the Holder in exercise of this Warrant is subject to the requirement
that such securities be registered under the Securities Act of 1933, as amended
(the "1933 Act"), and applicable state securities laws or exempt from
registration under such laws. The Holder of this Warrant shall be deemed to be a
shareholder of the Warrant Shares as to which this Warrant is exercised in
accordance herewith effective immediately after the close of business on the
date on which the Holder shall have delivered to the Company this Warrant in
proper form for exercise and payment by certified or official bank check or wire
transfer of the cash purchase price for the number of Warrant Shares as to which
the exercise is being made, notwithstanding that the stock transfer books of the
Company shall be then closed or that certificates representing such Warrant
Shares shall not then be physically delivered to the Holder.

        (b)  All or any portion of the Warrant Share Price may be paid by
surrendering Warrants effected by presentation and surrender of this Warrant to
the Company, or at the office of its Transfer Agent, if any, with a Cashless
Exercise Form annexed hereto duly executed (a "Cashless Exercise"). Such
presentation and surrender shall be deemed a waiver by the Company of the
Holder's obligation to pay all or any portion of the aggregate Warrant Share
Price. Except as provided in Section 3(b) below, in the event of a Cashless
Exercise, the Holder shall exchange its Warrant for that number of shares of
Common Stock determined by multiplying the number of Warrant Shares for which
the Holder desires to exercise this Warrant by a fraction, the numerator of
which shall be the difference between the then current market price per share of
the Common Stock and the Warrant Share Price, and the denominator of which shall
be the then current market price per share of Common Stock. For purposes of any
computation under this Section 1(b), the then current market price per share of
Common Stock at any date shall be deemed to be the average for the ten
consecutive business days immediately prior to the Cashless Exercise of the
daily closing prices of the Common Stock on the principal national securities
exchange on which the Common Stock is admitted to trading or listed, or if not
listed or admitted to trading on any such exchange, the closing prices as
reported by the Nasdaq National Market or, if applicable, the Nasdaq SmallCap
Market, or if not then included for quotation on the Nasdaq National Market or
the Nasdaq SmallCap Market, the average of the highest reported bid and lowest
reported asked prices as reported by the OTC Bulletin Board or the National
Quotations Bureau, as the case may be, or if not then publicly traded, the fair
market price, not less than book value thereof, of the Common Stock as
determined in good faith by the independent members of the Board of Directors of
the Company.

                                       2
<PAGE>

        (c)  If this Warrant shall be exercised in part only, the Company shall,
upon surrender of this Warrant for cancellation, execute and deliver a new
Warrant evidencing the rights of the Holder thereof to purchase the balance of
the Warrant Shares purchasable hereunder as to which the Warrant has not been
exercised. If this Warrant is exercised in part, such exercise shall be for a
whole number of Warrant Shares. Upon any exercise and surrender of this Warrant,
the Company (i) will issue and deliver to the Holder a certificate or
certificates in the name of the Holder for the largest whole number of Warrant
Shares to which the Holder shall be entitled and, if this Warrant is exercised
in whole, in lieu of any fractional Warrant Share to which the Holder otherwise
might be entitled, cash in an amount equal to the fair value of such fractional
Warrant Share (determined in such reasonable and equitable manner as the Board
of Directors of the Company shall in good faith determine), and (ii) will
deliver to the Holder such other securities, properties and cash which the
Holder may be entitled to receive upon such exercise, or the proportionate part
thereof if this Warrant is exercised in part, pursuant to the provisions of this
Warrant.

2.  Anti-Dilution Provisions.  The Warrant Share Price in effect at any time and
the number and kind of securities issuable upon exercise of this Warrant and the
Warrant Share Price shall be subject to adjustment from time to time upon
happening of certain events as follows:

    2.1 Reorganization, Reclassification, Consolidation, Merger or Sale. If any
capital reorganization, reclassification or any other change of capital stock of
the Company, or any consolidation or merger of the Company with another person,
or the sale or transfer of all or substantially all of its assets to another
person shall be effected in such a way that holders of shares of Common Stock
shall be entitled to receive stock, securities or assets with respect to or in
exchange for their shares of Common Stock, then provision shall be made by the
Company, in accordance with this Section 2.1, whereby the Holder hereof shall
thereafter have the right to purchase and receive, upon the basis and upon the
terms and conditions specified in this Warrant Agreement and in addition to or
in exchange for, as applicable, the Warrant Shares subject to this Warrant
immediately theretofore purchasable and receivable upon the exercise of the
rights represented hereby, such securities or assets as would have been issued
or payable with respect to or in exchange for the aggregate Warrant Shares
immediately theretofore purchasable and receivable upon the exercise of the
rights represented hereby if exercise of the Warrant had occurred immediately
prior to such reorganization, reclassification, consolidation, merger or sale.
The Company will not effect any such consolidation, merger, sale, transfer or
lease unless prior to the consummation thereof the successor entity (if other
than the Company) resulting from such consolidation or merger or the entity
purchasing such assets shall assume by written instrument (i) the obligation to
deliver to the Holder such securities or assets as, in accordance with the
foregoing provisions, the Holder may be entitled to purchase, and (ii) all other
obligations of the Company under this Warrant; provided, however, that the
failure to comply with the foregoing shall not affect the validity or legality
of such consolidation, merger, sale, transfer or lease. The provisions

                                       3
<PAGE>

of this Section 2.1 shall similarly apply to successive consolidations, mergers,
exchanges, sales, transfers or leases. In the event that in connection with any
such capital reorganization or reclassification, consolidation, merger, sale or
transfer, additional shares of Common Stock shall be issued in exchange,
conversion, substitution or payment, in whole or in part, for a security of the
Company other than Common Stock, any such issue shall be treated as an issue of
Common Stock covered by the provisions of Section 2.2 hereof.

    2.2   Stock Dividends and Securities Distributions. If, at any time or from
time to time after the date of this Warrant, the Company shall distribute to the
holders of shares of Common Stock (i) securities (including rights, warrants,
options or another form of convertible securities), (ii) property, other than
cash, or (iii) cash, without fair payment therefor, then, and in each such case,
the Holder, upon the exercise of this Warrant, shall be entitled to receive such
securities, property and cash which the Holder would hold on the date of such
exercise if, on the date of the distribution, the Holder had been the holder of
record of the shares of Common Stock issued upon such exercise and, during the
period from the date of this Warrant to and including the date of such exercise,
had retained such shares of Common Stock and the securities, property and cash
receivable by the Holder during such period, subject, however, to the Holder
agreeing to any conditions to such distribution as were required of all other
holders of shares of Common Stock in connection with such distribution.


     2.3  Other Adjustments. In addition to those adjustments set forth in
Sections 2.1 and 2.2, but without duplication of the adjustments to be made
under such Sections, if the Company:

                (i)    declares or pays a dividend or makes a distribution on
                       its Common Stock in shares of its Common Stock;

                (ii)   subdivides or reclassifies its outstanding shares of
                       Common Stock into a greater number of shares;

                (iii)  combines or reclassifies its outstanding shares of Common
                       Stock into a smaller number of shares;

                (iv)   makes a distribution on its Common Stock in shares of its
                       capital stock other than Common Stock; and/or

                (v)    issues, by reclassification of its Common Stock, any
                       shares of its capital stock;

then the number and kind of Warrant Shares purchasable upon exercise of this
Warrant shall be adjusted so that the Holder upon exercise hereof shall be
entitled to receive the kind and number of Warrant Shares or other securities of
the Company that the Holder would have owned or have been entitled to receive
after the happening of any of the

                                       4
<PAGE>

events described above had this Warrant been exercised immediately prior to the
happening of such event or any record date with respect thereto. An adjustment
made pursuant to this Section 2.3 shall become effective immediately after the
record date in the case of a dividend or distribution and shall become effective
immediately after the effective date in the case of a subdivision, combination
or issuance. If, as a result of an adjustment made pursuant to this Section 2.3,
the Holder of this Warrant thereafter surrendered for exercise shall become
entitled to receive shares of two or more classes of capital stock or shares of
Common Stock and any other class of capital stock of the Company, the Board of
Directors (whose determination shall be conclusive and shall be described in a
written notice to all holders of Warrants promptly after such adjustment) shall
determine the allocation of the adjusted Warrant Share Price between or among
shares of such classes of capital stock or shares of Common Stock and such other
class of capital stock.

        The adjustment to the number of Warrant Shares purchasable upon the
exercise of this Warrant described in this Section 2.3 shall be made each time
any event listed in paragraphs (i) through (v) of this Section 2.3 occurs.

        Simultaneously with all adjustments to the number and/or kind of
securities, property and cash under this Section 2.3 to be issued in connection
with the exercise of this Warrant, the Warrant Share Price will also be
appropriately and proportionately adjusted.

        In the event that at any time, as a result of an adjustment made
pursuant to this Section 2.3, the Holder of this Warrant thereafter shall become
entitled to receive any shares of the Company, other than Common Stock,
thereafter the number of such other shares so receivable upon exercise of this
Warrant 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 Sections 2.1 and 2.2 above and Section 2.4 below.

   2.4 Sale of Securities. In the event the Company, at any time after June __,
2000, issues or sells Common Stock, convertible preferred stock, options,
warrants, or other securities convertible into or exercisable for Common Stock
other than securities issued upon the conversion or exercise of any securities
outstanding as of June __, 2000, or pursuant to the Agency Agreement (as defined
below) in connection with the Offering (as defined in the Agency Agreement), at
a purchase price ("Purchase Price") less than the current market price per share
of Common Stock (determined in the manner contemplated by Section 1(b) above) on
the date the Company becomes obligated to make such issuance or sale, then the
Conversion Price shall be reduced to the price determined by multiplying the
Conversion Price in effect immediately prior to such issuance or sale by a
fraction, the numerator of which shall be the sum of (A) the number of shares of
Common Stock outstanding (exclusive of any treasury shares) immediately prior to
such issuance or sale multiplied by the current market price per share of Common

                                       5
<PAGE>

Stock on the date of such issuance or sale (determined in the manner
contemplated by Section 1(b) above), plus (B) the consideration received by the
Company upon such issuance or sale, and the denominator of which shall be the
product of (X) the total number of shares of Common Stock outstanding (exclusive
of any treasury shares) immediately after such issuance or sale, multiplied by
(Y) the current market price per share of Common Stock on the date of such
issuance or sale (determined in the manner contemplated by Section 1(b) above),
unless the Purchase Price is below the Warrant Share Price in effect immediately
prior to such issuance or sale, in which event the Warrant Share Price shall be
automatically reduced to such lower Purchase Price;

provided, however, that no adjustment to the Warrant Share Price or the number
and kind of Warrant Shares shall be made pursuant to this Section 2.4 in the
event (i) the Company grants options to employees, officers, directors or
consultants of the Company pursuant to contracts or plans approved by the Board
of Directors of the Company, (ii) of the issuance of securities to a "strategic
partner" as determined by the Board of Directors of the Company (which shall
include without limitation any securities issued to Infoseek Corporation or its
affiliates pursuant to that certain (1) Distribution Agreement by and between
the Company and Infoseek, ABC News Internet Ventures and ESPN Internet Ventures
(the "Go.com Parties") Corporation dated April 19, 1999; (2) Distribution
Agreement by and between the Company and Buena Vista Internet Group ("BVIG")
dated April 9, 1999 and (3) Amendment dated April 20, 2000 by and between the
Company, the Go.com parties and BVIG), (iii) the Company pays a dividend payable
in Common Stock, (iv) of the issuance of securities pursuant to an acquisition
transaction approved by the Board of Directors of the Company, (v) of the
issuance of warrants to lenders or lessors or other business partners of the
Company, (vi) the issuance of any securities (the "Issued Securities") upon
exercise or conversion of any derivative securities issued pursuant to that
certain Agency Agreement, dated as of June ___, 2000 by and between the Company
and Commonwealth (the "Agency Agreement") including, without limitation, any
subsequent adjustment in any such Issued Securities or any securities issued in
respect thereof or (vii) of the issuance of up to an aggregate of 500,000 shares
(as appropriately adjusted for stock splits, stock dividends, and similar
adjustments after the Issuance Date) of Common Stock (or convertible preferred
stock, options, warrants or other securities convertible into or exercisable for
Common Stock) at a purchase price less than the Warrant Share Price and not
otherwise excepted pursuant to clauses (i) through (vii) above.

        (a)   For the purpose of making any adjustment in the Warrant Share
Price as provided in this Section 2.4, the consideration received by the Company
for any issue or sale of Common Stock will be computed:


              (i)  to the extent it consists of cash, as the amount of cash
                   received by the Company before deduction of any offering
                   expenses payable by the Company and any underwriting or
                   similar commissions, compensation, or concessions paid or

                                       6
<PAGE>

                     allowed by the Company in connection with such issue or
                     sale;

              (ii)   to the extent it consists of property other than cash, at
                     the fair market value of that property as determined in
                     good faith by the Company's Board of Directors
                     (irrespective of the accounting treatment thereof); and

              (iii)  if Common Stock is issued or sold together with other stock
                     or securities (including convertible preferred stock,
                     options, warrants or securities convertible into or
                     exchangeable for common stock) or other assets of the
                     Company for a consideration which covers both, as the
                     portion of the consideration so received that may be
                     reasonably determined in good faith by the Company's Board
                     of Directors to be allocable to such Common Stock;
                     provided, however, that with respect to such other stock or
                     securities, such consideration as determined by the
                     Company's Board of Directors shall not be less than the
                     total consideration received by the Company for the
                     issuance of such other stock or securities plus the
                     additional aggregate consideration, if any, to be received
                     by the Company upon conversion or exchange thereof.

        (b)  If the Company (i) issues, grants or sells any rights or options to
subscribe for, purchase, or otherwise acquire shares of Common Stock, or (ii)
issues or sells any security convertible into shares of Common Stock, then, in
each case, the price per share of Common Stock issuable on the exercise of the
rights or options or the conversion of the securities will be determined by
dividing (x) the total amount, if any, received or receivable by the Company as
consideration for the granting or sale of the rights or options or the issue or
sale of the convertible securities (before fees and expenses), plus the minimum
aggregate amount of additional consideration payable to the Company on exercise
or conversion of the securities, by (y) the maximum number of shares of Common
Stock issuable on the exercise of conversion. Such granting or issue or sale
will be considered to be an issue or sale for cash of the maximum number of
shares of Common Stock issuable on exercise or conversion at the price per share
determined under this Section 2.4, and the Warrant Share Price will be adjusted
as above provided to reflect (on the basis of that determination) the issue or
sale. No further adjustment of the Warrant Share Price will be made as a result
of the actual issuance of shares of Common Stock on the exercise of any such
rights or options or the conversion of any such convertible securities.

        (c)  Upon the redemption or repurchase of any such securities or the
expiration or termination of the right to convert into, exchange for, or
exercise with

                                       7
<PAGE>

respect to, Common Stock, the Warrant Share Price will be readjusted to such
price as would have been obtained had the adjustment made upon their issuance
been made upon the basis of the issuance of only the number of such securities
as were actually converted into, exchanged for, or exercised with respect to,
Common Stock. If the purchase price or conversion or exchange rate provided for
in any such security changes at any time, then, upon such change becoming
effective, the Warrant Share Price then in effect will be readjusted to such
price as would have been obtained had the adjustment made upon the issuance of
such securities been made upon the basis of (i) the issuance of only the number
of shares of Common Stock theretofore actually delivered upon the conversion,
exchange or exercise of such securities, and the total consideration received
therefor, and (ii) the granting or issuance, at the time of such change, of any
such securities then still outstanding for the consideration, if any, received
by the Company therefor and to be received on the basis of such changed price or
rate.

    2.5 Notice of Adjustments. Upon the occurrence of each adjustment or
readjustment of the Warrant Share Price pursuant to this Section 2, the Company
at its expense will promptly compute such adjustment or readjustment in
accordance with the terms of this Warrant and prepare a certificate setting
forth such adjustment or readjustment, including a statement of the adjusted
Warrant Share Price or adjusted number of shares of Common Stock, if any,
issuable upon exercise of each Warrant, describing the transaction giving rise
to such adjustments and showing in detail the facts upon which such adjustment
or readjustment is based. The Company will forthwith mail, by first class mail,
postage prepaid, a copy of each such certificate to the Holder of this Warrant
at the address of such Holder as shown on the books of the Company, and to its
Transfer Agent.

    2.6  Other Notices.  If at any time:

         (a)  the Company shall (i) offer for subscription pro rata to the
holders of shares of the Common Stock any additional equity in the Company or
other rights; (ii) pay a dividend in additional shares of the Common Stock or
distribute securities or other property to the holders of shares of the Common
Stock (including, without limitation, evidences of indebtedness and equity and
debt securities); or (iii) issue securities convertible into, or rights or
warrants to purchase, securities of the Company;

         (b)  there shall be any capital reorganization or reclassification or
consolidation or merger of the Company with, or sale, transfer or lease of all
or substantially all of its assets to, another entity; or

         (c)  there shall be a voluntary or involuntary dissolution, liquidation
or winding up of the Company;

then, in any one or more of said cases, the Company shall give, by first class
mail, postage prepaid, to the Holder of this Warrant at the address of such
Holder as shown on the books of the Company, (a) at least 15 days' prior written
notice of the date on which

                                       8
<PAGE>

the books of the Company shall close or a record shall be taken for such
subscription rights, dividend, distribution or issuance, and (b) in the case of
any such reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation or winding up, at least 15 days' prior written notice
of the date when the same shall take place if no stockholder vote is required
and at least 15 days' prior written notice of the record date for stockholders
entitled to vote upon such matter if a stockholder vote is required. Such notice
in accordance with the foregoing clause (a) shall also specify, in the case of
any such subscription rights, the date on which the holders of shares of Common
Stock shall be entitled to exercise their rights with respect thereto, and such
notice in accordance with the foregoing clause (b) shall also specify the date
on which the holders of shares of Common Stock shall be entitled to exchange
their shares of Common Stock for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up, as the case may be. Failure to give the notice
referred to herein shall not affect the validity or legality of the action which
should have been the subject of the notice.

    2.7  No adjustment in the Warrant Share Price shall be required unless such
adjustment would require an increase or decrease of at least one cent ($0.01) in
such price; provided, however, that any adjustments which by reason of this
Section 2.8 are not required to be made shall be carried forward and taken into
account in any subsequent adjustment required to be made hereunder. All
calculations under this Section 2 shall be made to the nearest cent or to the
nearest one-hundredth of a share, as the case may be.

3.  Re-set of Warrant Share Price. In the event that the average closing bid
price for the Company's Common Stock for the 20 trading days preceding the two-
year anniversary of the date hereof is less than the Warrant Share Price, then
the Warrant Share Price shall be automatically reset to such lower price.

4.  No Voting Rights. This Warrant shall not be deemed to confer upon the Holder
any right to vote or to consent to or receive notice as a stockholder of the
Company, as such, in respect of any matters whatsoever, or any other rights or
liabilities as a stockholder, prior to the exercise hereof.

5.  Warrants Transferable. This Warrant and all rights hereunder are
transferable, in whole or in part, at the principal offices of the Company by
the Holder hereof, upon surrender of this Warrant properly endorsed; provided,
however, that in each case the minimum number of Warrant Shares being
transferred by the Holder shall not be less than 1,000 Warrant Shares; provided,
further, that without the prior written consent of the Company, this Warrant and
all rights hereunder may be transferred only (i) to an affiliate of the initial
Holder hereof or successor in interest to any such person in a transaction
exempt from registration under the 1933 Act; or (ii) pursuant to the
registration of this Warrant or the Warrant Shares under the 1933 Act or
subsequent to one year from the date hereof pursuant to an available exemption
from such registration. It shall be a

                                       9
<PAGE>

condition to transfer of this Warrant that the transferee agrees to be bound by
the restrictions on transfer contained in Section 3(b)(ix) of the Agency
Agreement.

6.  Warrants Exchangeable; Assignment; Loss, Theft, Destruction, Etc. This
Warrant is exchangeable, without expense, upon surrender hereof by the Holder
hereof at the principal offices of the Company, or at the office of its Transfer
Agent, if any, for new Warrants of like tenor representing in the aggregate the
right to subscribe for and purchase the Warrant Shares which may be subscribed
for and purchased hereunder, each such new Warrant to represent the right to
subscribe for and purchase such Warrant Shares as shall be designated by such
Holder hereof at the time of such surrender. Upon surrender of this Warrant to
the Company at its principal office, or at the office of its Transfer Agent, if
any, with an instrument of assignment duly executed and funds sufficient to pay
any transfer tax, the Company shall, without charge, execute and deliver a new
Warrant in the name of the assignee named in such instrument of assignment and
this Warrant shall promptly be cancelled. This Warrant may be divided or
combined with other warrants which carry the same rights upon presentation
hereof at the principal office of the Company, or at the office of its Transfer
Agent, if any, together with a written notice specifying the names and
denominations in which new Warrants are to be issued and signed by the Holder
hereof. The term "Warrant" as used herein includes any Warrants into which this
Warrant may be divided or exchanged. Upon receipt of evidence satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant and,
in the case of any such loss, theft or destruction, upon delivery of a bond or
indemnity satisfactory to the Company, or, in the case of any such mutilation,
upon surrender or cancellation of this Warrant, the Company will issue to the
Holder hereof a new Warrant of like tenor, in lieu of this Warrant, representing
the right to subscribe for and purchase the Warrant Shares which may be
subscribed for and purchased hereunder. Any such new Warrant executed and
delivered shall constitute an additional contractual obligation of the Company,
whether or not this Warrant so lost, stolen, destroyed, or mutilated shall be at
any time enforceable by anyone.

7.  Legends; Investment Representations.
