          REGISTRATION RIGHTS AGREEMENT, dated as of March 23, 2000,
          between Mediconsult.com, Inc., a Delaware corporation (the
          "Company"), and Andersen Consulting LLP, an Illinois limited
          liability partnership and its permitted assigns, (the
          "Warrant Holder").
          ------------------------------------------------------------

                                 Introduction
                                 ------------

          Pursuant to the Warrant Agreement, dated as of March 23, 2000 (the
"Warrant Agreement"), among the Company and the Warrant Holder, the Warrant
Holder is being issued a warrant (the "Warrant") to purchase certain shares of
common stock, par value $.001 per share or any other securities which may be
issuable upon exercise of the Warrant (the "Common Stock"), of the Company in
connection with the consummation of the transactions contemplated thereby.

          As a condition to the consummation of the transactions contemplated by
the Warrant Agreement, the Company is entering into this Agreement.

          The parties hereto agree as follows:

          1.   Definitions.  Terms used herein and not otherwise defined shall
               -----------
have the meanings given to them in the Warrant Agreement. As used herein, the
following terms have the following definitions:

          Commission means the Securities and Exchange Commission, or any other
          ----------
federal agency at the time administering the Securities Act.

          Distribution Period means (a) in the case of a distribution of
          -------------------
Registrable Shares in a firm commitment underwritten public offering, the period
of time until each underwriter has completed the distribution of all securities
purchased by it, and (b) in the case of any other distribution of Registrable
Shares the period ending on the earlier of (i) the sale of all Registrable
Shares covered by such registration and (ii) the termination of the registration
rights hereunder pursuant to Section 10.

          Holder means any Affiliate of the Warrant Holder holding the Warrant
          ------
or Registrable Shares hereunder.

          Registrable Shares means the shares of Common Stock issuable upon
          ------------------
exercise of the vested portion of the Warrant (or any substitute warrant issued
pursuant to Section 5 of the Warrant) as such number of shares may be adjusted
from time to time in accordance with the term thereof, and, any securities
issued with respect to such shares by way of a stock dividend, stock split,
combination, recapitalization, Corporate Change or other similar event (if and
only if such issuance occurs at a time when such Common Stock remains
Registrable Shares).  As to any particular Registrable Shares, such securities
shall cease to be Registrable Shares when (i) a registration statement with
respect to the sale of such securities shall have become effective under the
Securities Act and such securities shall have been disposed of in accordance
with such
<PAGE>

registration statement, (ii) they shall have been distributed to the public
pursuant to Rule 144 (or any successor provision) under the Securities Act,
(iii) they shall have been otherwise transferred, with new certificates for them
not bearing a legend restricting further transfer having been delivered by the
Company and subsequent disposition of them shall be unrestricted under the
Securities Act, or (iv) they shall have ceased to be outstanding.

          Securities Act means the Securities Act of 1933, as amended.
          --------------

          2.   Incidental Registration.  (a)    If at any time after the date
               -----------------------
hereof, the Company proposes to register any of its securities ("Company
Shares") under the Securities Act (other than on Forms S-4, S-8 or any other
form which does not permit registration of securities by selling stockholders
for sale to the public for cash) in connection with the proposed offer and sale
for cash either for its own account or on behalf of any holder of Company
Shares, it will give prompt written notice to the Holder of its intention to do
so at least ten business days prior to the earliest date on which the Company
anticipates that such registration will be declared effective by the Commission.
Upon the Holder's written request to the Company, given within five business
days after receipt of any such notice, to register any of the Holder's
Registrable Shares, the Company will use its commercially reasonable best
efforts to cause the Registrable Shares as to which registration shall have been
so requested to be included in the shares of Company Shares to be covered by the
registration statement proposed to be filed by the Company; provided, that
                                                            --------
nothing set forth in this Agreement shall prevent the Company from, at any time,
withdrawing, abandoning or delaying any registration of such Company Shares.

The Company shall have the sole right to select the managing underwriter or
underwriters.  The managing underwriter for such offering shall have the
authority, in its sole discretion, to reduce the number of Registrable Shares to
be included in such registration if and to the extent that it determines that
inclusion of such Registrable Shares would adversely effect the marketing of the
other Company Shares to be sold thereunder.  Any such reduction in the shares
included in any such offering shall be effected (i) first, by excluding Company
Shares ("Piggyback Shares") that otherwise would be included by virtue of
incidental or piggyback registration rights (but not demand registration rights)
granted to stockholders of the Company (including the Holder), which exclusion
shall be effected on a pro rata basis based upon the number of Company Shares so
requested to be registered in such offering by all such stockholders proposing
to sell Piggyback Shares and (ii) second, only to the extent necessary and after
the exclusion of all Piggyback Shares, by excluding Company Shares included in
such registration by the Company and any stockholder of the Company who shall
have exercised a demand registration right in connection with such offering,
which exclusion shall be effected on a pro rata basis based upon the number of
Company Shares proposed to be registered on behalf of the Company and on behalf
of any such holder of demand registration rights; provided, however, that it is
understood and agreed that the rights granted hereunder are subject to
previously existing registration rights granted to pursuant to the registration
rights agreement dated February 26, 1999 between the Company and Arnhold and S.
Bleichroeder Inc., and the registration rights agreement, dated February 26,
1999, between the Company and the Nazem entities and individuals, in each case
only to the extent inconsistent with this provision.

          (b)  If any registration pursuant to this Section 2 shall be
underwritten, in whole or in part, the Company or the managing underwriter or
underwriters may require that the

                                       2
<PAGE>

Registrable Shares requested for inclusion pursuant to this Section 2 be
included in the underwriting on the same terms and conditions as the securities
otherwise being sold through the underwriters.

          (c)  Notwithstanding anything to the contrary set forth in this
Agreement, if, at any time during which a prospectus is required to be delivered
in connection with the sale of Registrable Shares, the Company reasonably
determines in good faith that a development has occurred or a condition exists
as a result of which the registration statement or the related prospectus may
contain or incorporate by reference a material misstatement or omission, the
correction of which might (a) interfere with or affect the negotiation or
completion of any non-ordinary course transaction that is being contemplated by
the Company (whether or not a final decision has been made to undertake such
transaction), or (b) involve initial or continuing disclosure obligations that
the Company reasonably determines in good faith may not be in the best interest
of the Company or its stockholders, the Company will immediately notify the
Holders by telephone and in writing, and the Company may suspend the
effectiveness of the registration statement.  Upon receipt of such notification,
the Holders will immediately suspend all offers and transfers of any Registrable
Shares pursuant to the registration statement until such time as the Company
notifies the Holders that it has determined that such suspension period is
ended, which notification shall occur promptly after the Company has determined
that such suspension period has ended.

          3.   Preparation and Filing.  If and whenever the Company is under an
               ----------------------
obligation pursuant to the provisions of Section 2 to effect the registration of
any Registrable Shares, the Company shall, as expeditiously as practicable:

          (a)  prepare, provide opportunity for counsel for the Holder to
review, and diligently pursue the filing with the Commission of a registration
statement with respect to such securities and use its commercially reasonable
best efforts to cause such registration statement to become and remain effective
for the Distribution Period, but no longer;

          (b)  prepare, provide opportunity for counsel for the Holder to
review, and file with the Commission such amendments and supplements to such
registration statements and the prospectus used in connection therewith as may
be necessary to keep such registration statement effective for the Distribution
Period, but no longer;

          (c)  furnish to the holders of Registrable Shares included in such
registration statement such number of copies of a summary prospectus or other
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act and any amendments and supplements thereto,
and such other documents as such holders of Registrable Shares may reasonably
request in order to facilitate the public sale or other disposition of such
Registrable Shares;

          (d)  use its commercially reasonable best efforts to register or
qualify the Registrable Shares covered by such registration statement under the
securities or "blue sky" laws of such states as the Holder shall reasonably
request (provided, that the Company shall not be required to consent to general
         --------
service of process for all purposes in any jurisdiction where it is not then
qualified) and do any and all other acts or things which may be necessary or
advisable to

                                       3
<PAGE>

enable such seller to consummate the public sale or other disposition in such
jurisdictions of such securities;

          (e)  notify the Holder, at any time during the Distribution Period
when a prospectus relating to Registrable Shares covered by such registration
statement is required to be delivered under the Securities 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 and at the request of the Holder, prepare and furnish to the
Holder a reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such shares, such prospectus shall not include an untrue statement
of a material fact or omit 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; and

          (f)  cause all such Registrable Securities to be listed on each
securities exchange (including the Nasdaq National Market) on which similar
securities issued by the Company are then listed;

          (g)  provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (h)  enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities;

          (i)  make available for inspection by any seller of Registrable
Securities, any underwriter participating in any disposition pursuant to such
registration statement and any attorney, accountant or other agent retained by
any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement;

          (j)  otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission; and

          (k)  in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any securities included in such registration statement for sale in any
jurisdiction, the Company will notify each Seller of such Registrable Securities
of such stop order and use its reasonable best efforts promptly to obtain the
withdrawal of such order.

          (l)  Notwithstanding anything to the contrary contained herein, the
Company shall have the right to deregister any Registrable Shares that remain
unsold at the conclusion of any Distribution Period.

                                       4
<PAGE>

          4.   Transfer Restrictions.  Other than a Transfer to an Affiliate in
               ---------------------
compliance with the Securities Act, the Holder shall not offer, sell, contract
to sell or otherwise dispose of ("Transfer") more than 50% of the shares of
Common Stock registered for sale pursuant to Section 2 hereof in any three month
period; provided that if the Holder is prevented because of an underwriter
cutback from registering all the Registrable Shares requested to be registered,
the Transfer restriction shall apply to 50% of the shares of Common Stock
requested to be registered.

          5.   Holder's Lock-Up; Cooperation.  If any Registrable Shares of the
               -----------------------------
Holder are included in an underwritten registration pursuant to Section 2, the
Holder, as a condition to receiving the rights granted hereunder, may be
required to, and if required the Holder shall, enter into an agreement with the
managing underwriter or underwriters (a "Lock-up Agreement"), pursuant to which,
in addition to the transfer restrictions set forth in Section 4 above, the
Holder shall refrain from selling any shares of Common Stock not included in
such registration during the period of distribution of Common Stock by such
underwriters and for a period of up to 180 days following the effective date of
such registration.  In connection with each registration pursuant to Section 2
hereof, the Holder shall furnish in writing to the Company and any underwriter
participating in such offering such information with respect to himself and the
proposed distribution by him as shall be reasonably necessary in order to assure
compliance with Federal and applicable state securities laws.

          6.   Underwriting Agreement.  In connection with each registration
               ----------------------
pursuant to Section 2 covering an underwritten public offering, the Company and
the Holder agree to enter into a written agreement with the managing underwriter
or underwriters in such form and containing such provisions as are usual and
customary in the securities business for such an arrangement between reputable
underwriters and companies of the Company's size and investment stature;
provided that such agreement shall not contain any such provision applicable to
--------
the Company or the Holder which is inconsistent with the provisions of this
Agreement; and provided, further, that the time and place of the closing under
               --------  -------
said underwriting agreement shall be as mutually agreed upon between the Company
and such managing underwriter.

          7.   Expenses.  All expenses incurred in complying with this
               --------
Agreement, including, without limitation, all registration, qualification and
filing fees, fees and expenses of complying with securities and "blue sky" laws,
expenses, if any, and fees relating to the listing of the Registrable Shares on
the Nasdaq National Market or such other exchange as the Company's Common Stock
may then be listed or quoted, printing expenses and fees and disbursements of
the Company's counsel, and of the Company's independent certified public
accountants shall be paid by the Company; provided, that counsel to the Holder
                                          ---------
and all underwriting discounts and selling commissions applicable to the
Registrable Shares covered by registrations effected hereunder shall not be
borne by the Company but shall be borne by the Holder.

          8.   Indemnification.  (a)    In the event of any registration of any
               ---------------
Registrable Shares under the Securities Act pursuant to this Agreement or
registration or qualification of any Registrable Shares under state securities
or "blue sky" laws pursuant to this Agreement, the Company shall indemnify and
hold harmless the Holder, its partners, affiliates, officers and directors and
each other person or entity, if any, who controls such holder, within the
meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, to which

                                       5
<PAGE>

any of the foregoing persons may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any registration statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary prospectus or final prospectus contained therein, or any
amendment or supplement thereto, or any document prepared or furnished by the
Company incident to the registration or qualification of any Registrable Shares
pursuant to this Agreement, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading or, with respect to
any prospectus, necessary to make the statements therein in light of the
circumstances under which they were made, not misleading, or any violation by
the Company of the Securities Act, the Exchange Act of 1934 or state securities
or "blue sky" laws applicable to the Company and relating to action or inaction
required of the Company in connection with such registration or qualification
under such state securities or blue sky laws; and shall reimburse the Holder,
partner, officer, director or other person or entity acting on behalf of the
Holder and each such controlling person or entity for any legal or any other
expenses reasonably incurred by any of them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, that the
                                                             --------
Company shall not be liable (i) in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
the registration statement, any preliminary prospectus or final prospectus or
any amendment or supplement or any document incident to the registration or
qualification of any Registrable Shares pursuant to this Agreement in reliance
upon and in conformity with written information furnished to the Company by the
Holder or such underwriter specifically for use in the preparation thereof and
(ii) to any broker or other person acting on behalf of the Holder to the extent
that any such loss, claim, damage or liability arises out of or is based upon
any representation or other statement of such broker or other person that is not
in conformity with the preliminary prospectus or prospectus. The liability of
each Holder under this Section shall be limited to the proceeds (net of
underwriting commissions) received by such Holder from the sale of shares of
Registrable Shares covered by the registration statement.

          (b)  The Holder hereby indemnifies and holds harmless the Company,
each director of the Company, each officer of the Company who shall sign such
registration statement and any person who controls the Company within the
meaning of the Securities Act, and before Registrable Shares held by the Holder
shall be included in any registration pursuant to this Agreement, any
underwriter acting on the Holder's behalf shall agree to indemnify and hold
harmless the Company, each director of the Company, each officer of the Company
who shall sign such registration statement and any person who controls the
Company within the meaning of the Securities Act (in each case in the same
manner and to the same extent as set forth in (a) above) with respect to any
untrue statement or omission from such registration statement, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereof, if such untrue statement or omission was made in reliance upon and in
conformity with written information furnished to the Company by the Holder or
such underwriter, as the case may be, specifically for use in the preparation of
such registration statement, preliminary prospectus, final prospectus or
amendment or supplement.

                                       6
<PAGE>

          (c)  Each person or entity entitled to indemnification hereunder (the
"indemnified party") shall give notice to the party required to provide
indemnification (the "indemnifying party") promptly after such indemnified party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the indemnifying party (at its expense) to assume the defense of any
claim or any litigation resulting therefrom; provided, that counsel for the
                                             --------
indemnifying party, who shall conduct the defense of such claim or litigation,
shall be reasonably satisfactory to the indemnified party, and the indemnified
party may participate in such defense, but only at such indemnified party's
expense; and provided, further, that the failure of any indemnified party to
             --------  -------
give notice as provided herein shall not relieve the indemnifying party of its
obligations under this Section 7 except to the extent that the omission results
in a failure of actual notice to the indemnifying party and such indemnifying
party is damaged as a result of the failure to give notice. It is understood
that the indemnifying party shall not, in connection with any action or related
actions in the same jurisdiction, be liable for the fees and disbursements of
more than one separate firm qualified in such jurisdiction to act as counsel for
the indemnified party.  No indemnifying party, in the defense of any such claim
or litigation, shall, except with the consent of each indemnified party, consent
to entry of any judgment or enter into any settlement which does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation.  The Company agrees to make such provisions as are reasonably
requested by any indemnified party for contribution to such party in the event
the Company's indemnification under this Section is unavailable for any reason.
Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in any underwriting agreement entered
into in connection with any offering are in conflict with the provisions of this
Section, the provisions in the underwriting agreement shall control with respect
to such offering.

          (d)  Maintain Current Public Information.  The Company shall file all
               -----------------------------------
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and regulations adopted by the SEC thereunder and shall take such
further action as any Holder or Holders may reasonably request, all to the
extent required to enable such Holders to sell Registrable Shares pursuant to
(a) Rule 144 adopted by the SEC under the Securities Act (as such rule may be
amended from time to time) or any similar rule or regulation hereafter adopted
by the SEC or (b) a registration statement on Form S-3 or any similar
registration form hereafter adopted by the SEC.  Upon request, the Company shall
deliver to any Holder a certificate by its chief executive officer or chief
financial officer as to whether it has complied with such requirements.


          9.   Representations and Warranties.  (a)   The Company hereby
               ------------------------------
represents and warrants to the Holder that:

          (i)  The execution and delivery of this Agreement and the

     fraudulent transfer, reorganization, moratorium and other laws of general
     applicability relating to or affecting creditors' rights and to general
     equitable principles.

          (ii) Neither the execution and delivery of this Agreement, nor the
     consummation of the transactions contemplated hereby nor compliance by the

     Company, (B) conflict with or result in a default (or give rise to any
     right of termination, cancellation or acceleration) under any of the
     provisions of any note, bond, lease, mortgage, indenture, license,
     franchise, permit, agreement or other instrument or obligation to which the
     Company is a party, or by which the Company or the Company's properties or
     assets, may be bound or affected, except for such conflict, breach or
     default as to which requisite waivers or consents shall be obtained before
     the Closing, or (C) violate any law, statute, rule or regulation or order,
     writ, injunction or decree applicable to the Company or the Company's
     properties or assets or (D) result in the creation or imposition of any
     security interest, lien or other encumbrance upon any of the Company's
     properties or assets.  No consent or approval by, or any notification of or
     filing with, any person, firm, corporation, partnership, joint venture,
     association or entity (governmental or private) (each, a "person" and
     collectively, "persons") is required in connection with the execution,
     delivery and performance by the Company of this Agreement or the
     consummation of the transactions contemplated hereby, except as set forth
     in the Warrant Agreement.

     general equitable principles.

          (ii) Neither the execution and delivery of this Agreement, nor the

     or acceleration) under any of the provisions of any note, bond, lease,
     mortgage, indenture, license, franchise, permit, agreement or other
     instrument or obligation to which the Warrant Holder is a party, or by
