                         REGISTRATION RIGHTS AGREEMENT

     THIS REGISTRATION RIGHTS AGREEMENT, dated as of April 24, 2000, between the
investor or investors signatory hereto (each a "Purchaser" and together the
"Purchasers") and InChorus.com (the "Company").

     WHEREAS, simultaneously with the execution and delivery of this Agreement,
pursuant to a Common Stock Purchase Agreement dated the date hereof (the
"Purchase Agreement") the Purchasers have committed to purchase up to $5,000,000
worth of the Company's Common Stock (terms not defined herein shall have the
meanings ascribed to them in the Purchase Agreement); and

     WHEREAS, the Company desires to grant to the Purchasers the registration
rights set forth herein with respect to the Shares and the Shares issuable upon
exercise of the Warrants from time to time (hereinafter referred to collectively
as the "Stock" or "Securities" of the Company).

     NOW, THEREFORE, the parties hereto mutually agree as follows:

     Section 1.  Registrable Securities. As used herein the term "Registrable
                 ----------------------
Securities" means the Securities until the earliest of (i) all Securities have
been disposed of pursuant to the Registration Statement, (ii) all Securities
have been sold under circumstances under which all of the applicable conditions
of Rule 144 (or any similar provision then in force) under the Securities Act
("Rule 144") are met, (iii) all Securities have been otherwise transferred to
persons who may trade such Securities without restriction under the Securities
Act, and the Company has delivered a new certificate or other evidence of
ownership for such Securities not bearing a restrictive legend or (iv) such time
as, in the opinion of counsel to the Company, all Securities may be sold without
any time, volume or manner limitations pursuant to Rule 144(k) (or any similar
provision then in effect) under the Securities Act. The term "Registrable
Securities" means any and/or all of the securities falling within the foregoing
definition of a "Registrable Security." In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Common Stock, such adjustment shall be deemed to be made
in the definition of "Registrable Security" as is appropriate in order to
prevent any dilution or enlargement of the rights granted pursuant to this
Agreement.

     Section 2.  Restrictions on Transfer. The Purchasers acknowledge and
                 ------------------------
understand that in the absence of an effective Registration Statement
authorizing the resale of the Securities as provided herein, the Securities are
"restricted securities" as defined in Rule 144 promulgated under the Act. The
Purchasers understand that no disposition or transfer of the Securities may be
made by Purchasers in the absence of (i) an opinion of counsel to the
Purchasers, in form and substance reasonably satisfactory to the Company, that
such transfer may be made without registration under the Securities Act or (ii)
such registration.
<PAGE>

     With a view to making available to the Purchasers the benefits of Rule 144
under the Securities Act or any other similar rule or regulation of the
Commission that may at any time permit the Purchasers to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to:

     (a)  comply with the provisions of paragraph (c)(1) of Rule 144; and

     (b)  file with the Commission in a timely manner all reports and other
documents required to be filed by the Company pursuant to Section 13 or 15(d)
under the Exchange Act; and, if at any time it is not required to file such
reports but in the past had been required to or did file such reports, it will,
upon the request of any Purchaser, make available other information as required
by, and so long as necessary to permit sales of, its Registrable Securities
pursuant to Rule 144.

     Section 3.  Registration Rights With Respect to the Securities.
                 --------------------------------------------------

     (a)  The Company agrees that it will prepare and file with the Securities
and Exchange Commission ("Commission"), within forty-five (45) days after the
date hereof, a registration statement (on Form S-3 and/or S-1, or other
appropriate form of registration statement) under the Securities Act (the
"Registration Statement"), at the sole expense of the Company (except as
provided in Section 3(c) hereof), in respect of Purchasers, so as to permit a
public offering and resale of the Securities under the Act by Purchasers.

     The Company shall use its best efforts to cause the Registration Statement
to become effective within five (5) days of SEC clearance to request
acceleration of effectiveness. If the Registration Statement is not declared
effective by August 31, 2000 this Agreement and the Purchase Agreement shall
terminate. The Company will notify Purchasers of the effectiveness of the
Registration Statement within one Trading Day of such event.

     (b)  The Company will maintain the Registration Statement or post-effective
amendment filed under this Section 3 hereof effective under the Securities Act
until the earlier of (i) the date that none of the Securities are or may become
issued and outstanding, (ii) the date that all of the Securities have been sold
pursuant to the Registration Statement, (iii) the date the holders thereof
receive an opinion of counsel to the Company, which counsel shall be reasonably
acceptable to the Purchasers, that the Securities may be sold under the
provisions of Rule 144 without limitation as to volume, (iv) all Securities have
been otherwise transferred to persons who may trade such shares without
restriction under the Securities Act, and the Company has delivered a new
certificate or other evidence of ownership for such securities not bearing a
restrictive legend, or (v) all Securities may be sold without any time, volume
or manner limitations pursuant to Rule 144(k) or any similar provision then in
effect under the Securities Act in the opinion of counsel to the Company, which
opinion shall be accepted by the Company's Transfer Agent (the "Effectiveness
Period").

     (c)  All fees, disbursements and out-of-pocket expenses and costs incurred
by the Company in connection with the preparation and filing of the Registration
Statement under subparagraph 3(a) and in complying with applicable securities
and Blue Sky laws (including, without limitation, all attorneys' fees of the
Company) shall be borne by the Company. The

                                       2
<PAGE>

Purchasers, severally and not jointly, shall bear the cost of underwriting
and/or brokerage discounts, fees and commissions, if any, applicable to the
Securities being registered and the fees and expenses of their counsel. The
Purchasers and their counsel shall have a reasonable period, not to exceed ten
(10) Trading Days, to review the proposed Registration Statement or any
amendment thereto, prior to filing with the Commission, and the Company shall
provide each Purchaser with copies of any comment letters received from the
Commission with respect thereto within two (2) Trading Days of receipt thereof.
The Company shall make reasonably available for inspection by Purchasers, any
underwriter participating in any disposition pursuant to the Registration
Statement, and any attorney, accountant or other agent retained by such
Purchasers or any such underwriter all relevant financial and other records,
pertinent corporate documents and properties of the Company and its
subsidiaries, and cause the Company's officers, directors and employees to
supply all information reasonably requested by such Purchasers or any such
underwriter, attorney, accountant or agent in connection with the Registration
Statement, in each case, as is customary for similar due diligence examinations;
provided, however, that all records, information and documents that are
designated in writing by the Company, in good faith, as confidential,
proprietary or containing any material non-public information shall be kept
confidential by each such Purchaser and any such underwriter, attorney,
accountant or agent (pursuant to an appropriate confidentiality agreement in the
case of any such Purchaser or agent), unless such disclosure is made pursuant to
judicial process in a court proceeding (after first giving the Company an
opportunity promptly to seek a protective order or otherwise limit the scope of
the information sought to be disclosed) or is required by law, or such records,
information or documents become available to the public generally or through a
third party not in violation of an accompanying obligation of confidentiality;
and provided further that, if the foregoing inspection and information gathering
would otherwise disrupt the Company's conduct of its business, such inspection
and information gathering shall, to the maximum extent possible, be coordinated
on behalf of the Purchasers and the other parties entitled thereto by one firm
of counsel designed by and on behalf of the majority in interest of Purchasers
and other parties. The Company shall qualify any of the securities for sale in
such states as such Purchasers reasonably designate and shall furnish
indemnification in the manner provided in Section 6 hereof. However, the Company
shall not be required to qualify in any state which will require an escrow or
other restriction relating to the Company and/or the sellers, or which will
require the Company to qualify to do business in such state or require the
Company to file therein any general consent to service of process. The Company
at its expense will supply the Purchasers with copies of the Registration
Statement and the prospectus included therein and other related documents in
such quantities as may be reasonably requested by the Purchasers.

     (d)  The Company shall not be required by this Section 3 to include
Purchasers' Securities in any Registration Statement which is to be filed if, in
the opinion of counsel for both the Purchasers and the Company (or, should they
not agree, in the opinion of another counsel experienced in securities law
matters acceptable to counsel for the Purchasers and the Company) the proposed
offering or other transfer as to which such registration is requested is exempt
from applicable federal and state securities laws and would result in all
purchasers or transferees obtaining securities which are not "restricted
securities", as defined in Rule 144 under the Securities Act.

     (e)  If at any time or from time to time after the effective date of the
Registration Statement, the Company notifies the Purchasers in writing of the
existence of a Potential

                                       3
<PAGE>

Material Event (as defined in Section 3(f) below), the Purchasers shall not
offer or sell any Securities or engage in any other transaction involving or
relating to Securities, from the time of the giving of notice with respect to a
Potential Material Event until such Purchasers receive written notice from the
Company that such Potential Material Event either has been disclosed to the
public or no longer constitutes a Potential Material Event; provided, however,
that if the Company so suspends the right to such holders of Securities for more
than twenty (20) days in the aggregate during any twelve month period, during
the periods the Registration Statement is required to be in effect then the
Company must compensate the Purchasers for any net decline in market value of
the Securities held by Purchasers at the beginning of such suspension through
the end of such suspension. If a Potential Material Event shall occur prior to
the date the Registration Statement is filed, then the Company's obligation to
file the Registration Statement shall be delayed without penalty for not more
than thirty (30) days. The Company must give Purchasers notice in writing at
least two (2) Trading Days prior to the first day of the blackout period, if
lawful to do so.

     (f)  "Potential Material Event" means any of the following: (a) the
possession by the Company of material information that is not ripe for
disclosure in a registration statement, as determined in good faith by the Chief
Executive Officer or the Board of Directors of the Company or that disclosure of
such information in the Registration Statement would be detrimental to the
business and affairs of the Company; or (b) any material engagement or activity
by the Company which would, in the good faith determination of the Chief
Executive Officer or the Board of Directors of the Company, be adversely
affected by disclosure in a registration statement at such time, which
determination shall be accompanied by a good faith determination by the Chief
Executive Officer or the Board of Directors of the Company that the Registration
Statement would be materially misleading absent the inclusion of such
information.

     Section 4.  Cooperation with Company. Purchasers will cooperate with the
                 ------------------------
Company in all respects in connection with this Agreement, including timely
supplying all information reasonably requested by the Company (which shall
include all information regarding the Purchasers and proposed manner of sale of
the Registrable Securities required to be disclosed in the Registration
Statement) and executing and returning all documents reasonably requested in
connection with the registration and sale of the Registrable Securities and
entering into and performing its obligations under any underwriting agreement,
if the offering is an underwritten offering, in usual and customary form, with
the managing underwriter or underwriters of such underwritten offering. The
Purchasers shall consent to be named as an underwriter in the Registration
Statement. Purchasers each acknowledge that in accordance with current
Commission policy, the Purchasers will be named as the underwriters of the
Securities in the Registration Statement.

     Section 5.  Registration Procedures. If and whenever the Company is
                 -----------------------
required by any of the provisions of this Agreement to effect the registration
of any of the Registrable Securities under the Act, the Company shall (except as
otherwise provided in this Agreement), as expeditiously as possible, subject to
the Purchasers' assistance and cooperation as reasonably required:

     (a)  (i) prepare and file with the Commission such amendments and
supplements to the Registration Statement and the prospectus used in connection
therewith as may be

                                       4
<PAGE>

necessary to keep such registration statement effective and to comply with the
provisions of the Act with respect to the sale or other disposition of all
securities covered by such registration statement whenever the Purchasers of
such Registrable Securities shall desire to sell or otherwise dispose of the
same (including prospectus supplements with respect to the sales of securities
from time to time in connection with a registration statement pursuant to Rule
415 promulgated under the Act) and (ii) take all lawful action such that each of
(A) the Registration Statement and any amendment thereto does not, when it
becomes effective, contain 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 and (B) the Prospectus forming part of the
Registration Statement, and any amendment or supplement thereto, does not at any
time during the Registration Period 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, in light of the circumstances under which they
were made, not misleading.

     (b)  (i)  prior to the filing with the Commission of any Registration
Statement (including any amendments thereto) and the distribution or delivery of
any prospectus (including any supplements thereto), subject to Section 3(c)
herein, provide draft copies thereof to the Purchasers and reflect in such
documents all such comments as the Purchasers (and their counsel) reasonably may
propose and (ii) furnish to each Purchaser such numbers of copies of a
prospectus including a preliminary prospectus or any amendment or supplement to
any prospectus, as applicable, in conformity with the requirements of the Act,
and such other documents, as such Purchaser may reasonably request in order to
facilitate the public sale or other disposition of the securities owned by such
Purchaser;

     (c)  register and qualify the Registrable Securities covered by the
Registration Statement under such other securities or blue sky laws of such
jurisdictions as the Purchasers shall reasonably request (subject to the
limitations set forth in Section 3(d) above), and do any and all other acts and
things which may be necessary or advisable to enable each Purchaser to
consummate the public sale or other disposition in such jurisdiction of the
securities owned by such Purchaser, except that, as provided for in Section 3(c)
herein, the Company shall not for any such purpose be required to qualify to do
business as a foreign corporation in any jurisdiction wherein it will require an
escrow or other restriction relating to the Company and/or the Purchasers, or
which it is not so qualified or required to file therein any general consent to
service of process;

     (d)  list such Registrable Securities on the Principal Market, and any
other exchange on which the Common Stock of the Company is then listed, if the
listing of such Registrable Securities is then permitted under the rules of such
exchange or the Nasdaq Stock Market;

     (e)  notify each Purchaser at any time when a prospectus relating thereto
covered by the Registration Statement is required to be delivered under the Act,
of the happening of any event of which it has knowledge as a result of which the
prospectus included in the 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 the Company
shall prepare and file a curative amendment under Section 5(a) as quickly as
commercially possible;

                                       5
<PAGE>

     (f)  as promptly as practicable after becoming aware of such event, notify
each Purchaser who holds Registrable Securities being sold (or, in the event of
an underwritten offering, the managing underwriters) of the issuance by the
Commission or any state authority of any stop order or other suspension of the
effectiveness of the Registration Statement at the earliest possible time and
take all lawful action to effect the withdrawal, recession or removal of such
stop order or other suspension;

     (g)  cooperate with the Purchasers to facilitate the timely preparation and
delivery of certificates for the Registrable Securities to be offered pursuant
to the Registration Statement and enable such certificates for the Registrable
Securities to be in such denominations or amounts, as the case may be, as the
Purchasers reasonably may request and registered in such names as the Purchasers
may request; and, within three (3) Trading Days after a Registration Statement
which includes Registrable Securities is declared effective by the Commission,
deliver and cause legal counsel selected by the Company to deliver to the
transfer agent for the Registrable Securities (with copies to the Purchasers
whose Registrable Securities are included in such Registration Statement) an
appropriate instruction and, to the extent necessary, an opinion of such
counsel;

     (h)  take all such other lawful actions reasonably necessary to expedite
and facilitate the disposition by the Purchasers of their Registrable Securities
in accordance with the intended methods therefor provided in the prospectus
which are customary for issuers to perform under the circumstances;

     (i)  in the event of an underwritten offering, promptly include or
incorporate in a Prospectus supplement or post-effective amendment to the
Registration Statement such information as the managers reasonably agree should
be included therein and to which the Company does not reasonably object and make
all required filings of such Prospectus supplement or post-effective amendment
as soon as practicable after it is notified of the matters to be included or
incorporated in such Prospectus supplement or post-effective amendment; and

     (j)  maintain a transfer agent and registrar for its Common Stock.

     Section 6.  Indemnification.
                 ---------------

     (a)  The Company agrees to indemnify and hold harmless the Purchasers and
each person, if any, who controls the Purchasers within the meaning of the
Securities Act ("Distributing Purchasers") against any losses, claims, damages
or liabilities, joint or several (which shall, for all purposes of this
Agreement, include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees), to which the Distributing
Purchasers 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 any untrue statement or alleged untrue statement
of any material fact contained in the Registration Statement, or any related
preliminary prospectus, final prospectus or amendment or supplement thereto, 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; provided, however, that the Company will not
be liable 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,

                                       6
<PAGE>

preliminary prospectus, final prospectus or amendment or supplement thereto in
reliance upon, and in conformity with, written information furnished to the
Company by such Distributing Purchaser, specifically for use in the preparation
thereof. This Section 6(a) shall not inure to the benefit of any Distributing
Purchaser with respect to any person asserting such loss, claim, damage or
liability who purchased the Registrable Securities which are the subject thereof
if such Distributing Purchaser failed to send or give (in violation of the
Securities Act or the rules and regulations promulgated thereunder) a copy of
the prospectus contained in such Registration Statement to such person at or
prior to the written confirmation to such person of the sale of such Registrable
Securities, where such Distributing Purchaser was obligated to do so under the
Securities Act or the rules and regulations promulgated thereunder. This
indemnity agreement will be in addition to any liability which the Company may
otherwise have.

     (b)  Each Purchaser and Distributing Purchaser, severally and not jointly,
agrees that it will indemnify and hold harmless the Company, and each officer,
director of the Company or person, if any, who controls the Company within the
meaning of the Securities Act, against any losses, claims, damages or
liabilities (which shall, for all purposes of this Agreement, include, but not
be limited to, all reasonable costs of defense and investigation and all
reasonable attorneys' fees) to which the Company or any such officer, director
or controlling person 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 any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement, or any
related preliminary prospectus, final prospectus or amendment or supplement
thereto, or arise out of or are based upon the omission or the alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, but in each case only to the extent
that such untrue statement or alleged untrue statement or omission or alleged
omission was made in the Registration Statement, preliminary prospectus, final
prospectus or amendment or supplement thereto in reliance upon, and in
conformity with, written information furnished to the Company by such Purchaser
and Distributing Purchaser, specifically for use in the preparation thereof.
This indemnity agreement will be in addition to any liability which the
Distributing Purchasers may otherwise have. Notwithstanding anything to the
contrary herein, the Distributing Purchasers shall not be liable under this
Section 6(b) for any amount in excess of the net proceeds to such Distributing
Purchaser as a result of the sale of Registrable Securities pursuant to the
Registration Statement.

     (c)  Promptly after receipt by an indemnified party under this Section 6 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 6, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve the indemnifying
party from any liability which it may have to any indemnified party except to
the extent of actual prejudice demonstrated by the indemnifying party. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate in, and, to the extent that it may wish, jointly with
any other indemnifying party similarly notified, assume the defense thereof,
subject to the provisions herein stated and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party will not be liable to such indemnified party
under this Section 6 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof

                                       7
<PAGE>

other than reasonable costs of investigation, unless the indemnifying party
shall not pursue the action to its final conclusion. The indemnified party shall
have the right to employ separate counsel in any such action and to participate
in the defense thereof, but the fees and expenses of such counsel shall not be
at the expense of the indemnifying party if the indemnifying party has assumed
the defense of the action with counsel reasonably satisfactory to the
indemnified party; provided that if the indemnified party is a Distributing
Purchaser, the fees and expenses of such counsel shall be at the expense of the
indemnifying party if (i) the employment of such counsel has been specifically
authorized in writing by the indemnifying party, or (ii) the named parties to
any such action (including any impleaded parties) include both the Distributing
Purchaser and the indemnifying party and the Distributing Purchaser shall have
been advised by such counsel that there may be one or more legal defenses
available to the indemnifying party different from or in conflict with any legal
defenses which may be available to the Distributing Purchaser (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the Distributing Purchaser, it being understood, however, that the
indemnifying party shall, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable only for the reasonable
fees and expenses of one separate firm of attorneys for the Distributing
Purchaser, which firm shall be designated in writing by the Distributing
Purchaser). No settlement of any action against an indemnified party shall be
made without the prior written consent of the indemnified party, which consent
shall not be unreasonably withheld.

     All fees and expenses of the indemnified party (including reasonable costs
of defense and investigation in a manner not inconsistent with this Section and
all reasonable attorneys' fees and expenses) shall be paid to the indemnified
party, as incurred, within ten (10) Trading Days of written notice thereof to
the indemnifying party (regardless of whether it is ultimately determined that
an indemnified party is not entitled to indemnification hereunder; provided,
that the indemnifying party may require such indemnified party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such indemnified party is not entitled to indemnification
hereunder).

     Section 7.  Contribution. In order to provide for just and equitable
                 ------------
contribution under the Securities Act in any case in which (i) the indemnified
party makes a claim for indemnification pursuant to Section 6 hereof but is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 6 hereof provide
for indemnification in such case, or (ii) contribution under the Securities Act
may be required on the part of any indemnified party, then the Company and the
applicable Distributing Purchaser shall contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (which shall, for
all purposes of this Agreement, include, but not be limited to, all reasonable
costs of defense and investigation and all reasonable attorneys' fees), in
either such case (after contribution from others) on the basis of relative fault
as well as any other relevant equitable considerations. The relative fault shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company on the one hand
or the applicable Distributing Purchaser on the other hand, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or

                                       8
<PAGE>

omission. The Company and the Distributing Purchasers agree that it would not be
just and equitable if contribution pursuant to this Section 7 were determined by
pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in this Section 7. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this Section 7 shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

     Notwithstanding any other provision of this Section 7, in no event shall
any (i) Purchaser be required to undertake liability to any person under this
Section 7 for any amounts in excess of the dollar amount of the net proceeds to
be received by such Purchaser from the sale of such Purchaser's Registrable
Securities (after deducting any fees, discounts and commissions applicable
thereto) pursuant to any Registration Statement under which such Registrable
Securities are to be registered under the Securities Act and (ii) underwriter be
required to undertake liability to any person hereunder for any amounts in
excess of the aggregate discount, commission or other compensation payable to
such underwriter with respect to the Registrable Securities underwritten by it
and distributed pursuant to the Registration Statement.

     Section 8.  Notices. All notices, demands, requests, consents, approvals,
                 -------
and other communications required or permitted hereunder shall be in writing
and, unless otherwise specified herein, shall be delivered as set forth in the
Purchase Agreement.

     Section 9.  Assignment. Neither this Agreement nor any rights of any
                 ----------
Purchaser or the Company hereunder may be assigned by such party to any other
person. Notwithstanding the foregoing, (a) the provisions of this Agreement
shall inure to the benefit of, and be enforceable by, any transferee of any of
the Common Stock purchased by the such Purchaser pursuant to the Purchase
Agreement other than through open-market sales, and (b) upon the prior written
consent of the Company, which consent shall not be unreasonably withheld or
delayed in the case of an assignment to an affiliate of a Purchaser, a
Purchaser's interest in this Agreement may be assigned at any time, in whole or
in part, to any other person or entity (including any affiliate of such
Purchaser) who agrees to be bound hereby.

     Section 10. Counterparts/Facsimile. This Agreement may be executed in two
                 ----------------------
or more counterparts, each of which shall constitute an original, but all of
which, when together shall constitute but one and the same instrument, and shall
become effective when one or more counterparts have been signed by each party
hereto and delivered to the other party. In lieu of the original, a facsimile
transmission or copy of the original shall be as effective and enforceable as
the original.

     Section 11. Remedies. The remedies provided in this Agreement are
                 --------
cumulative and not exclusive of any remedies provided by law. If any term,
provision, covenant or restriction of this Agreement is held by a court of
competent jurisdiction to be invalid, illegal, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions set forth herein
shall remain in full force and effect and shall in no way be affected, impaired
or invalidated, and

                                       9
<PAGE>

the parties hereto shall use their best efforts to find and employ an
alternative means to achieve the same or substantially the same result as that
contemplated by such term, provision, covenant or restriction. It is hereby
stipulated and declared to be the intention of the parties that they would have
executed the remaining terms, provisions, covenants and restrictions without
including any of such that may be hereafter declared invalid, illegal, void or
unenforceable.

     Section 12. Conflicting Agreements. The Company shall not enter into any
                 ----------------------
agreement with respect to its securities that is inconsistent with the rights
granted to the holders of Registrable Securities in this Agreement or otherwise
prevents the Company from complying with all of its obligations hereunder.

     Section 13. Headings. The headings in this Agreement are for reference
                 --------

                 -------------
construed in accordance with the laws of the State of New York applicable to

York City, New York, and shall reach and render a decision in writing (concurred
in by a majority of the members of the Board of Arbitration) with respect to the
amount, if any, which the losing party is required to pay to the other party in
respect of a claim filed. In connection with rendering its decisions, the Board
of Arbitration shall adopt and follow the laws of the State of New York. To the

costs, including attorney's fees, from the non-prevailing party.

     Section 15. Severability. If any provision of this Agreement shall for any
                 ------------
reason be held invalid or unenforceable, such invalidity or unenforceablity
shall not affect any other provision hereof and this Agreement shall be
construed as if such invalid or unenforceable provision had never been contained
herein. Terms not otherwise defined herein shall be defined in accordance with
the Agreement.

NEITHER THIS WARRANT NOR THE SHARES ISSUABLE UPON EXERCISE HEREOF HAVE BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT")
OR ANY OTHER APPLICABLE SECURITIES LAWS IN RELIANCE UPON AN EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH OTHER SECURITIES LAWS.
NEITHER THIS WARRANT NOR THE SHARES ISSUABLE UPON EXERCISE HEREOF MAY BE SOLD,
PLEDGED, TRANSFERRED, ENCUMBERED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR IN A TRANSACTION
WHICH IS EXEMPT FROM REGISTRATION UNDER THE PROVISIONS OF THE SECURITIES ACT.

                            STOCK PURCHASE WARRANT

                 To Purchase 50,000 Shares of Common Stock of

                                 INCHORUS.COM

          THIS CERTIFIES that, for value received, Plumrose Holdings, Ltd. (the
"Holder"), is entitled, upon the terms and subject to the conditions hereinafter
set forth, at any time on or after April 24, 2000 (the "Issuance Date") and on
or prior to the close of business on April 24, 2003 (the "Termination Date") but
not thereafter, to subscribe for and purchase from InChorus.com, a Nevada
corporation (the "Company"), up to fifty thousand (50,000) shares (the "Warrant
Shares") of Common Stock, $0.001 par value, of the Company (the "Common Stock").
The purchase price of one share of Common Stock (the "Exercise Price") under
this Warrant shall be $1.50 (120% of the closing bid price on the Trading Day
prior to the Closing Date). The Exercise Price and the number of shares for
which the Warrant is exercisable shall be subject to adjustment as provided
herein. In the event of any conflict between the terms of this Warrant and the
Common Stock Purchase Agreement dated April 24, 2000 pursuant to which this
Warrant has been issued (the "Purchase Agreement"), the Purchase Agreement shall
control. Capitalized terms used and not otherwise defined herein shall have the
meanings set forth for such terms in the Purchase Agreement.

          1.   Title to Warrant. Prior to the Termination Date hereof and
               ----------------
subject to compliance with applicable laws, this Warrant and all rights
hereunder are transferable, in whole or in part, at the office or agency of the
Company by the holder hereof in person or by duly authorized attorney, upon
surrender of this Warrant together with the Assignment Form annexed hereto
properly endorsed.

          2.   Authorization of Shares. The Company covenants that all shares of
               -----------------------
Common Stock which may be issued upon the exercise of rights represented by this
Warrant will, upon exercise of the rights represented by this Warrant, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges in respect of the issue

                                       1
<PAGE>

thereof (other than taxes in respect of any transfer occurring contemporaneously
with such issue).

          3.   Exercise of Warrant. Except as provided in Section 4 herein,
               -------------------
exercise of the purchase rights represented by this Warrant may be made at any
time or times on or after the Issuance Date hereof, and before the close of
business on the Termination Date hereof. Exercise of this Warrant or any part
hereof shall be effected by the surrender of this Warrant and the Notice of
Exercise Form annexed hereto duly executed, at the office of the Company (or
such other office or agency of the Company as it may designate by notice in
writing to the registered holder hereof at the address of such holder appearing
on the books of the Company) and upon payment of the Exercise Price of the
shares thereby purchased by wire transfer or cashier's check drawn on a United
States bank, the holder of this Warrant shall be entitled to receive a
certificate for the number of shares of Common Stock so purchased. Certificates
for shares purchased hereunder shall be delivered to the holder hereof within
three (3) Trading Days after the date on which this Warrant shall have been
exercised as aforesaid. This Warrant shall be deemed to have been exercised and
such certificate or certificates shall be deemed to have been issued, and Holder
or any other person so designated to be named therein shall be deemed to have
become a holder of record of such shares for all purposes, as of the date the
Warrant has been exercised by payment to the Company of the Exercise Price and
all taxes required to be paid by Holder, if any, pursuant to Section 5 prior to
the issuance of such shares, have been paid. If this Warrant shall have been
exercised in part, the Company shall, at the time of delivery of the certificate
or certificates representing Warrant Shares, deliver to Holder a new Warrant
evidencing the rights of Holder to purchase the unpurchased shares of Common
Stock called for by this Warrant, which new Warrant shall in all other respects
be identical with this Warrant. If the a registration statement permitting the
resale of the Shares issuable upon exercise of this Warrant is not then
effective, this Warrant may also be exercised by means of a "cashless exercise"
in which the holder shall be entitled to receive a certificate for the number of
shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = the average of the high and low trading prices per share of Common Stock
on the Trading Day preceding the date of such election;

(B) =  the Exercise Price of the Warrants; and

(X) = the number of shares issuable upon exercise of the Warrants in accordance
with the terms of this Warrant.

          4.   No Fractional Shares or Scrip. No fractional shares or scrip
               -----------------------------
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to the Exercise Price.

          5.   Charges, Taxes and Expenses. Issuance of certificates for shares
               ---------------------------
of Common Stock upon the exercise of this Warrant shall be made without charge
to the holder hereof for any issue or transfer tax or other incidental expense
in respect of the issuance of such certificate, all of which taxes and expenses
shall be paid by the Company, and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be

                                       2
<PAGE>

directed by the holder of this Warrant; provided, however, that in the event
certificates for shares of Common Stock are to be issued in a name other than
the name of the holder of this Warrant, this Warrant when surrendered for
exercise shall be accompanied by the Assignment Form attached hereto duly
executed by the holder hereof; and the Company may require, as a condition
thereto, the payment of a sum sufficient to reimburse it for any transfer tax
incidental thereto.

          6.   Closing of Books. The Company will not close its shareholder
               ----------------
books or records in any manner which prevents the timely exercise of this
Warrant.

          7.   Transfer, Division and Combination. (a) Subject to compliance
               ----------------------------------
with any applicable securities laws, transfer of this Warrant and all rights
hereunder, in whole or in part, shall be registered on the books of the Company
to be maintained for such purpose, upon surrender of this Warrant at the
principal office of the Company, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by Holder or its
agent or attorney and funds sufficient to pay any transfer taxes payable upon
the making of such transfer. Upon such surrender and, if required, such payment,
the Company shall execute and deliver a new Warrant or Warrants in the name of
the assignee or assignees and in the denomination or denominations specified in
such instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall
promptly be cancelled. A Warrant, if properly assigned, may be exercised by a
new holder for the purchase of shares of Common Stock without having a new
Warrant issued.

                    (b)  This Warrant may be divided or combined with other
Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued, signed by Holder or its agent or attorney.
Subject to compliance with Section 7(a), as to any transfer which may be
involved in such division or combination, the Company shall execute and deliver
a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided
or combined in accordance with such notice.

                    (c)  The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
Section 7.

                    (d)  The Company agrees to maintain, at its aforesaid
office, books for the registration and the registration of transfer of the
Warrants.

          8.   No Rights as Shareholder until Exercise. This Warrant does not
               ---------------------------------------
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company prior to the exercise hereof. Upon the surrender of this Warrant
and the payment of the aggregate Exercise Price, the Warrant Shares so purchased
shall be and be deemed to be issued to such holder as the record owner of such
shares as of the close of business on the later of the date of such surrender or
payment.

          9.   Loss, Theft, Destruction or Mutilation of Warrant. The Company
               -------------------------------------------------
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant certificate
or any stock certificate relating to the Warrant Shares, and in case of loss,
theft or destruction, of indemnity or security reasonably

                                       3
<PAGE>

satisfactory to it (which shall not include the posting of any bond), and upon
surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock
certificate.

          10.  Saturdays, Sundays, Holidays, etc. If the last or appointed day
               ---------------------------------
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a Saturday,
Sunday or legal holiday.

          11.  Adjustments of Exercise Price and Number of Warrant Shares. (a)
               ----------------------------------------------------------
Stock Splits, etc. The number and kind of securities purchasable upon the
-----------------
exercise of this Warrant and the Exercise Price shall be subject to adjustment
from time to time upon the happening of any of the following. In case the
Company shall (i) pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to holders of its outstanding Common
Stock, (ii) subdivide its outstanding shares of Common Stock into a greater
number of shares of Common Stock, (iii) combine its outstanding shares of Common
Stock into a smaller number of shares of Common Stock or (iv) issue any shares
of its capital stock in a reclassification of the Common Stock, then the number
of Warrant Shares purchasable upon exercise of this Warrant immediately prior
thereto shall be adjusted so that the holder of this Warrant shall be entitled
to receive the kind and number of Warrant Shares or other securities of the
Company which he would have owned or have been entitled to receive had such
Warrant been exercised in advance thereof. Upon each such adjustment of the kind
and number of Warrant Shares or other securities of the Company which are
purchasable hereunder, the holder of this Warrant shall thereafter be entitled
to purchase the number of Warrant Shares or other securities resulting from such
adjustment at an Exercise Price per Warrant Share or other security obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares purchasable pursuant hereto immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company resulting from such adjustment. An adjustment made pursuant to
this paragraph shall become effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

                    (b)  Reorganization, Reclassification, Merger, Consolidation
                         -------------------------------------------------------
or Disposition of Assets. In case the Company shall reorganize its capital,
------------------------
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then Holder shall have the right thereafter to receive, upon
exercise of this Warrant, the number of shares of common stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation,
and Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a holder of
the number of

                                       4
<PAGE>

shares of Common Stock for which this Warrant is exercisable immediately prior
to such event. In case of any such reorganization, reclassification, merger,
consolidation or disposition of assets, the successor or acquiring corporation
(if other than the Company) shall expressly assume the due and punctual
observance and performance of each and every covenant and condition of this
Warrant to be performed and observed by the Company and all the obligations and
liabilities hereunder, subject to such modifications as may be deemed
appropriate (as determined in good faith by resolution of the Board of Directors
of the Company) in order to provide for adjustments of shares of Common Stock
for which this Warrant is exercisable which shall be as nearly equivalent as
practicable to the adjustments provided for in this Section 11. For purposes of
this Section 11, "common stock of the successor or acquiring corporation" shall
include stock of such corporation of any class which is not preferred as to
dividends or assets over any other class of stock of such corporation and which
is not subject to redemption and shall also include any evidences of
indebtedness, shares of stock or other securities which are convertible into or
exchangeable for any such stock, either immediately or upon the arrival of a
specified date or the happening of a specified event and any warrants or other
rights to subscribe for or purchase any such stock. The foregoing provisions of
this Section 11 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

          12.  Voluntary Adjustment by the Company. The Company may at any time
               -----------------------------------
during the term of this Warrant, reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

          13.  Notice of Adjustment. Whenever the number of Warrant Shares or
               --------------------
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the holder of this Warrant notice of such adjustment or adjustments setting
forth the number of Warrant Shares (and other securities or property)
purchasable upon the exercise of this Warrant and the Exercise Price of such
Warrant Shares (and other securities or property) after such adjustment, setting
forth a brief statement of the facts requiring such adjustment and setting forth
the computation by which such adjustment was made. Such notice, in the absence
of manifest error, shall be conclusive evidence of the correctness of such
adjustment.

          14.  Notice of Corporate Action.  If at any time:
               --------------------------

                    (a)  the Company shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

                    (b)  there shall be any capital reorganization of the
Company, any reclassification or recapitalization of the capital stock of the
Company or any consolidation or merger of the Company with, or any sale,
transfer or other disposition of all or substantially all the property, assets
or business of the Company to, another corporation or,

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

                                       5
<PAGE>

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other
property deliverable upon such disposition, dissolution, liquidation or winding
up. Each such written notice shall be sufficiently given if addressed to Holder
at the last address of Holder appearing on the books of the Company and
delivered in accordance with Section 16(d).

          15.  Authorized Shares. The Company covenants that during the period
               -----------------
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares to provide for the issuance of the
Warrant Shares upon the exercise of any purchase rights under this Warrant. The
Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Principal Market
upon which the Common Stock may be listed.

                    The Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of Holder against impairment. Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any shares of
Common Stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise immediately prior to such increase in par
value, (b) take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant, and (c) use all commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof as may be necessary
to enable the Company to perform its obligations under this Warrant.

                    Upon the request of Holder, the Company will at any time
during the period this Warrant is outstanding acknowledge in writing, in form
reasonably satisfactory to Holder, the continuing validity of this Warrant and
the obligations of the Company hereunder.

                                       6
<PAGE>

                    Before taking any action which would cause an adjustment
reducing the current Exercise Price below the then par value, if any, of the
shares of Common Stock issuable upon exercise of the Warrants, the Company shall
take any corporate action which may be necessary in order that the Company may
validly and legally issue fully paid and non-assessable shares of such Common
Stock at such adjusted Exercise Price.

                    Before taking any action which would result in an adjustment
in the number of shares of Common Stock for which this Warrant is exercisable or
in the Exercise Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

          16.  Miscellaneous.
               -------------

                    (a)  Jurisdiction. This Warrant shall be binding upon any
                         ------------
successors or assigns of the Company. This Warrant shall constitute a contract
under the laws of New York without regard to its conflict of law principles or
rules, and be subject to arbitration pursuant to the terms set forth in the
Purchase Agreement.

                    (b)  Restrictions. The holder hereof acknowledges that the
                         ------------
Warrant Shares acquired upon the exercise of this Warrant, if not registered,
will have restrictions upon resale imposed by state and federal securities laws.

                    (c)  Nonwaiver and Expenses. No course of dealing or any
                         ----------------------
delay or failure to exercise any right hereunder on the part of Holder shall
operate as a waiver of such right or otherwise prejudice Holder's rights, powers
or remedies, notwithstanding all rights hereunder terminate on the Termination
Date hereof. If the Company willfully fails to comply with any material
provision of this Warrant, the Company shall pay to Holder such amounts as shall
be sufficient to cover any costs and expenses including, but not limited to,
reasonable attorneys' fees, including those of appellate proceedings, incurred
by Holder in collecting any amounts due pursuant hereto or in otherwise
enforcing any of its rights, powers or remedies hereunder.

                    (d)  Notices. Any notice, request or other document required

or permitted to be given or delivered to the holder hereof by the Company shall
be delivered in accordance with the notice provisions of the Purchase Agreement.

                    (e)  Limitation of Liability. No provision hereof, in the
                         -----------------------
absence of affirmative action by Holder to purchase shares of Common Stock, and
no enumeration herein of the rights or privileges of Holder hereof, shall give
rise to any liability of Holder for the purchase price of any Common Stock or as
a stockholder of the Company, whether such liability is asserted by the Company
or by creditors of the Company.

                    (f)  Remedies. Holder, in addition to being entitled to
                         --------
exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Warrant. The Company
agrees that monetary damages would not be

                                       7

adequate compensation for any loss incurred by reason of a breach by it of the
provisions of this Warrant and hereby agrees to waive the defense in any action
for specific performance that a remedy at law would be adequate.

                    (g)  Successors and Assigns. Subject to applicable
                         ----------------------
securities laws, this Warrant and the rights and obligations evidenced hereby
shall inure to the benefit of and be binding upon the successors of the Company
and the successors and permitted assigns of Holder. The provisions of this
Warrant are intended to be for the benefit of all Holders from time to time of
this Warrant and shall be enforceable by any such Holder or holder of Warrant
Shares.

                    (h)  Indemnification. The Company agrees to indemnify and
                         ---------------
hold harmless Holder from and against any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, claims, costs, attorneys' fees,
expenses and disbursements of any kind which may be imposed upon, incurred by or
asserted against Holder in any manner relating to or arising out of any failure
by the Company to perform or observe in any material respect any of its
covenants, agreements, undertakings or obligations set forth in this Warrant;
provided, however, that the Company will not be liable hereunder to the extent
that any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs, attorneys' fees, expenses or disbursements are
found in a final non-appealable judgment by a court to have resulted from
Holder's negligence, bad faith or willful misconduct in its capacity as a
stockholder or warrantholder of the Company.

                    (i)  Amendment. This Warrant may be modified or amended or
                         ---------
the provisions hereof waived with the written consent of the Company and the
Holder.

                    (j)  Severability. Wherever possible, each provision of this
                         ------------
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

                    (k)  Headings. The headings used in this Warrant are for the
                         --------
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.
