        COMPOSITE INDUSTRIES OF AMERICA, INC.

        CALLABLE WARRANT


        Date of Original Issuance:
        December 3, 2001

        Composite Industries of America, Inc. (formerly known as World Homes,
Inc), a Nevada corporation (the "Company"), hereby certifies that, for value
received, Burlington Street LLC or its registered assigns ("Holder"), is
entitled, subject to the terms set forth below, to purchase from the Company
up to a total of 2,173,913 shares of common stock, $.001 par value per share
(the "Common Stock"), of the Company (each such share, a "Warrant Share" and
all such shares, the "Warrant Shares") at an exercise price per share equal to
$0.01 (the "Exercise Price"), at any time and from time to time from and after
the date hereof and through and including December 3, 2006 (the "Expiration
Date"), and subject to the following terms and conditions.  Certain terms used
herein are defined in Exhibit A attached hereto.

                1.      Registration of Warrant.  The Company shall register
this Warrant, upon records to be maintained by the Company for that purpose
(the "Warrant Register"), in the name of the record Holder hereof from time to
time.  The Company may deem and treat the registered Holder of this Warrant as
the absolute owner hereof for the purpose of any exercise hereof or any
distribution to the Holder, and for all other purposes, and the Company shall
not be affected by notice to the contrary.

                2.      Registration of Transfers and Exchanges.

                        (a)     The Company shall register the transfer of any
portion of this Warrant in the Warrant Register, upon surrender of this
Warrant, with the Form of Assignment attached hereto duly completed and
signed, to the Transfer Agent or to the Company at its address for notice set
forth in Section 12.  Upon any such registration or transfer, a new warrant to
purchase Common Stock, in substantially the form of this Warrant (any such new
warrant, a "New Warrant"), evidencing the portion of this Warrant so
transferred shall be issued to the transferee and a New Warrant evidencing the
remaining portion of this Warrant not so transferred, if any, shall be issued
to the transferring Holder.  The acceptance of the New Warrant by the
transferee thereof shall be deemed the acceptance of such transferee of all of
the rights and obligations of a holder of a Warrant.

                        (b)     This Warrant is exchangeable, upon the
surrender hereof by the Holder to the office of the Company at its address for
notice set forth in Section 12 for one or more New Warrants, evidencing in the
aggregate the right to purchase the number of Warrant Shares which may then be
purchased hereunder.  Any such New Warrant will be dated the date of such
exchange.

                3.      Duration, Exercise and Redemption of Warrants.

                        (a)     Exercise By Holder

                                At any time between the date on which the
Commitment Period expires and 5:30 p.m.(New York City time) on the Expiration
Date, the Holder shall be entitled to exercise this Warrant to purchase all or
a portion of the Warrant Shares which have not been previously issued and with
respect to which this Warrant has not been previously redeemed or canceled in
accordance with the terms hereof.  At 5:30 P.M., New York City time on the
Expiration Date, the portion of this Warrant not exercised prior thereto shall
be and become void and of no value.

                        (b)     Company Call Option

                                (i)  Subject to the terms and conditions set
forth herein, prior to 5:30 p.m. (New York City time) on any Trading Day
during the period between November 13, 2001 and the Trading Day immediately
preceding the expiration of the Commitment Period (the "Call Expiration
Date"), the Company may deliver written notices to the Holder (each, a "Call
Notice" and the Trading Day a Call Notice is delivered, a "Delivery Date"), of
the Company's election to call, for a price of $.001 per Warrant Share, up to
a number of Warrant Shares equal to the quotient obtained by dividing (x)
$1,000,000 (not including any Investment Amount paid to the Company by the
Holder), by (y) the closing bid price of the Common Stock for the Trading Day
immediately preceding November 13, 2001.  The portion of this Warrant subject
to a Call Notice will be canceled and of no further effect from and after 5:30
p.m. (New York City time) on the third Trading Day following Delivery Date
(the "Call Expiration Time").

                (ii)    No new Call Notice may be delivered: (i) until the
expiration of the Call Expiration Time for the immediately preceding Call
Notice and (ii) unless the conditions set forth in Section 3(c) have been
either satisfied by the Company or waived by the Holder.

                        (c)     Conditions Precedent to Delivery of Call
Notice by Company

        The right of the Company to deliver a Call Notice is subject to the
satisfaction or waiver by the Holder, at or before the applicable Call
Expiration Time, of each of the following conditions (and, if after delivery
thereof  any of the following conditions shall cease to be met, such Call
Notice shall be null and void ab initio):

                        (1)     The representations and warranties of the
Company contained in the Purchase Agreement shall be true and correct as of
each of the applicable Delivery Dates and Call Expiration Times, as though
first made on and as of such Delivery Date and Call Expiration Time (other
than representations and warranties which relate to a specific date (which
shall not include representations and warranties relating to the "date
hereof"), which representations and warranties shall be true as of such
specific date);

                        (2)     The Company shall have performed, satisfied
and complied in all material respects with all covenants (including timely
delivery of Warrant Shares in accordance with Section 3(d)), and agreements in
the Transaction Documents to be performed, satisfied or complied with by the
Company at or prior to the applicable Delivery Date and Call Expiration Time;

                        (3)     The Registration Statement  shall be effective
on the Delivery Date and as at the Call Expiration Time, not subject to any
stop order or suspension, and the Registration Statement shall cover all of
the Warrant Shares subject to such Call Notice;

                        (4)     No statute, rule, regulation, executive order,
decree, ruling or injunction shall have been enacted, entered, promulgated or
endorsed by any court or governmental authority of competent jurisdiction and
in force on the Delivery Date which prohibits the consummation of any of the
transactions contemplated by the Transaction Documents;

                        (5)     Since the date hereof, no event or series of
events which reasonably would be expected to have or result in a Material
Adverse Effect (as defined in the Purchase Agreement) and no Change of Control
Transaction shall have occurred;

                        (6)     On the Delivery Date, the Common Stock shall
be trading on the OTC Bulletin Board ("OTC"), Nasdaq National Market, Nasdaq
Smallcap Market, New York Stock Exchange or American Stock Exchange (each, a
"Subsequent Market");

                        (7)     No approval of the shareholders of the Company
shall be required under the rules of the Nasdaq Stock Market or any other
Subsequent Market on which the Common Stock is traded or listed for trading in
order to issue the number of Warrant Shares indicated in the applicable Call
Notice; and

                        (8)     The Company shall have sold to the Holder, Put
Shares, for which Holder paid a purchase price of $1,000,000 pursuant to the
Purchase Agreement.

                        (d)     Delivery of Warrant Shares to Holder

        Upon delivery of an executed Form of Election to Purchase, together
with the grid attached hereto as Annex A duly completed and signed, to the
Company at its address for notice set forth in Section 12  and upon payment of
the Exercise Price multiplied by the number of Warrant Shares that the Holder
intends to purchase hereunder, in the manner provided hereunder, all as
specified by the Holder in the Form of Election to Purchase, the Company shall
promptly (but in no event later than 3 Business Days after the Date of
Exercise (as defined herein)) issue or cause to be issued and cause to be
delivered to or upon the written order of the Holder and in such name or names
as the Holder may designate, a certificate for the Warrant Shares issuable
upon such exercise, free of restrictive legends except in the event that a
registration statement covering the resale of the Warrant Shares and naming
the Holder as a selling stockholder thereunder is not then effective and the
Warrant Shares are not freely transferable without volume restrictions
pursuant to Rule 144(k) promulgated under the Securities Act of 1933, as
amended (the "Securities Act"). Any person so designated by the Holder to
receive Warrant Shares shall be deemed to have become holder of record of such
Warrant Shares as of the Date of Exercise of this Warrant.  The Company shall,
upon request of the Holder, if available, use its best efforts to deliver
Warrant Shares hereunder electronically through the Depository Trust
Corporation or another established clearing corporation performing similar
functions.  To effect an exercise hereunder, the Holder shall not be required
to physically surrender this Warrant to the Company unless all the Warrant
Shares have been exercised.  Exercises hereunder shall have the effect of
lowering the number of Warrant Shares in an amount equal to the applicable
exercise, which shall be evidenced by entries set forth on the attached Annex
A.  The Holder and the Company shall maintain records showing the number of
Warrant Shares exercised and the date of such exercises.  In the event of any
dispute or discrepancy, the records of the Holder shall be controlling and
determinative in the absence of manifest error.  The Holder and any assignee,
by acceptance of this Warrant, acknowledge and agree that, by reason of the
provisions of this paragraph, following exercise of a portion of this Warrant,
the number of shares issuable upon exercise of this Warrant may be less than
the amount stated on the face hereof.

                        A "Date of Exercise" means the date on which the
Company shall have received the Form of Election to Purchase completed and
duly signed. This Warrant shall be exercisable, either in its entirety or,
from time to time, for a portion of the number of Warrant Shares.

                        (e)     Rescission and Buy-In.

        If the Company fails to deliver to the Holder a certificate or
certificates representing the Warrant Shares issuable upon an exercise by the
third Trading Day after the Date of Exercise, then the Holder will have the
right to rescind such exercise. In addition, if the Company fails to deliver
to the Holder a certificate or certificates representing the Warrant Shares
pursuant to an exercise by the third Trading Day after the Date of Exercise,
and if after such third Trading Day the Holder purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of
a sale by the Holder of the Warrant Shares which the Holder anticipated
receiving upon such exercise (a "Buy-In"), then the Company shall (1) pay in
cash to the Holder the amount by which (x) the Holder's total purchase price
(including brokerage commissions, if any) for the shares of Common Stock so
purchased exceeds (y) the amount obtained by multiplying (A) the number of
Warrant Shares that the Company was required to deliver to the Holder in
connection with the exercise at issue by (B) the closing bid price of the
Common Stock at the time of the obligation giving rise to such purchase
obligation and (2) at the option of the Holder, either reinstate the portion
of the Warrant and equivalent number of Warrant Shares for which such exercise
was not honored or deliver to the Holder the number of shares of Common Stock
that would have been issued had the Company timely complied with its exercise
and delivery obligations hereunder .  For example, if the Holder purchases
Common Stock having a total purchase price of $11,000 to cover a Buy-In with
respect to an attempted exercise of shares of Common Stock with a market price
on the date of exercise totaled $10,000, under clause (A) of the immediately
preceding sentence the Company shall be required to pay the Holder $1,000.
The Holder shall provide the Company written notice indicating the amounts
payable to the Holder in respect of the Buy-In.

                4.      Piggyback Registration Rights. This Warrant is subject
to the piggyback registration rights granted under the Registration Rights
Agreement and such piggyback registration rights shall continue until all of
the Holder's Warrant Shares have been sold in accordance with an effective
registration statement or upon the Expiration Date.  The Company will pay all
registration expenses in connection therewith.

                5.      Payment of Taxes.  The Company will pay all
documentary stamp taxes attributable to the issuance of Warrant Shares upon
the exercise of this Warrant; provided, however, that the Company shall not be
required to pay any tax which may be payable in respect of any transfer
involved in the registration of any certificates for Warrant Shares or
Warrants in a name other than that of the Holder.  The Holder shall be
responsible for all other tax liability that may arise as a result of holding
or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

                6.      Replacement of Warrant.  If this Warrant is mutilated,
lost, stolen or destroyed, the Company shall issue or cause to be issued in
exchange and substitution for and upon cancellation hereof, or in lieu of and
substitution for this Warrant, a New Warrant, but only upon receipt of
evidence reasonably satisfactory to the Company of such loss, theft or
destruction and indemnity, if requested, satisfactory to it.  Applicants for a
New Warrant under such circumstances shall also comply with such other
reasonable regulations and procedures and pay such other reasonable charges as
the Company may prescribe.

                7.      Reservation of Warrant Shares.  The Company covenants
that it will at all times reserve and keep available out of the aggregate of
its authorized but unissued Common Stock, solely for the purpose of enabling
it to issue Warrant Shares upon exercise of this Warrant as herein provided,
the number of Warrant Shares which are then issuable and deliverable upon the
exercise of this entire Warrant, free from preemptive rights or any other
actual contingent purchase rights of persons other than the Holder (taking
into account the adjustments and restrictions of Section 8).  The Company
covenants that all Warrant Shares that shall be so issuable and deliverable
shall, upon issuance and the payment of the applicable Exercise Price in
accordance with the terms hereof, be duly and validly authorized, issued and
fully paid and nonassessable.

                8.      Certain Adjustments.  The Exercise Price and number of
Warrant Shares issuable upon exercise of this Warrant are subject to
adjustment from time to time as set forth in this Section 8.  Upon each such
adjustment of the Exercise Price pursuant to this Section 8, the Holder shall
thereafter prior to the Expiration Date be entitled to purchase, at the
Exercise Price resulting from such adjustment, the number of Warrant Shares
obtained by multiplying the Exercise Price in effect immediately prior to such
adjustment by the number of Warrant Shares issuable upon exercise of this
Warrant immediately prior to such adjustment and dividing the product thereof
by the Exercise Price resulting from such adjustment.

                (a)     If the Company, at any time while this Warrant is
outstanding, (i) shall pay a stock dividend (except scheduled dividends paid
on outstanding preferred stock as of the date hereof which contain a stated
dividend rate) or otherwise make a distribution or distributions on shares of
its Common Stock or on any other class of capital stock payable in shares of
Common Stock, (ii) subdivide outstanding shares of Common Stock into a larger
number of shares, or (iii) combine outstanding shares of Common Stock into a
smaller number of shares, the Exercise Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding before such event and of which
the denominator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding after such event.  In such event, the
number of Warrant shares issuable under this Warrant shall be equitably
adjusted to reflect such event (e.g. in the event of a 2:1 stock split of the
Common Stock, the number of Warrant shares shall be increased to twice the
number available for purchase prior to the record date for such stock split).
Any adjustment made pursuant to this Section shall become effective
immediately after the record date for the determination of stockholders
entitled to receive such dividend or distribution and shall become effective
immediately after the effective date in the case of a subdivision or
combination, and shall apply to successive subdivisions and combinations.

                (b)     In case of any reclassification of the Common Stock or
any compulsory share exchange pursuant to which the Common Stock is converted
into other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification or share exchange, and the Holder
shall be entitled upon such event to receive such amount of securities or
property equal to the amount of Warrant Shares such Holder would have been
entitled to had such Holder exercised this Warrant immediately prior to such
reclassification or share exchange.  The terms of any such reclassification or
share exchange shall include such terms so as to continue to give to the
Holder the right to receive the securities or property set forth in this
Section 8(b) upon any exercise following any such reclassification or share
exchange.

                (c)     If the Company, at any time while this Warrant is
outstanding, shall distribute to all holders of Common Stock (and not to
holders of this Warrant) evidences of its indebtedness or assets or rights or
warrants to subscribe for or purchase any security (excluding those referred
to in Sections 8(a), (b) and (d)), then in each such case the Exercise Price
shall be determined by multiplying the Exercise Price in effect immediately
prior to the record date fixed for determination of stockholders entitled to
receive such distribution by a fraction of which the denominator shall be the
Exercise Price determined as of the record date mentioned above, and of which
the numerator shall be such Exercise Price on such record date less the then
fair market value at such record date of the portion of such assets or
evidence of indebtedness so distributed applicable to one outstanding share of
Common Stock as determined by the Company's independent certified public
accountants that regularly examines the financial statements of the Company
(an "Appraiser").

                (d)     In case of any (1) merger or consolidation of the
Company with or into another Person, or (2) sale by the Company of more than
one-half of the assets of the Company (on a book value basis) in one or a
series of related transactions, the Holder shall have the right thereafter to
(A) exercise this Warrant for the shares of stock and other securities, cash
and property receivable upon or deemed to be held by holders of Common Stock
following such merger, consolidation or sale, and the Holder shall be entitled
upon such event or series of related events to receive such amount of
securities, cash and property as the Common Stock for which this Warrant could
have been exercised immediately prior to such merger, consolidation or sales
would have been entitled or (B) in the case of a merger or consolidation, (x)
require the surviving entity to issue common stock purchase warrants equal to
the number Warrant Shares to which this Warrant then permits, which newly
warrant shall be identical  to this Warrant, and (y) simultaneously with the
issuance of such warrant, the Holder of such warrant shall have the right to
exercise such warrant only into shares of stock and other securities, cash and
property receivable upon or deemed to be held by holders of Common Stock
following such merger or consolidation or (C) require the surviving entity
from such merger,  acquisition or business combination to pay to the Holder,
in cash, the Black Scholes value of this Warrant.   In the case of clause (B),
the exercise price for such new warrant shall be based upon the amount of
securities, cash and property that each share of Common Stock would receive in
such transaction and the Exercise Price of this Warrant immediately prior to
the effectiveness or closing date for such transaction. The terms of any such
merger, sale or consolidation shall include such terms so as continue to give
the Holder the right to receive the securities, cash and property set forth in
this Section upon any conversion or redemption following such event. This
provision shall similarly apply to successive such events.

                (e)     For the purposes of this Section 8, the following
clauses shall also be applicable:

                                (i)  Record Date.  In case the Company shall
take a record of the holders of its Common Stock for the purpose of entitling
them (A) to receive a dividend or other distribution payable in Common Stock
or in securities convertible or exchangeable into shares of Common Stock, or
(B) to subscribe for or purchase Common Stock or securities convertible or
exchangeable into shares of Common Stock, then such record date shall be
deemed to be the date of the issue or sale of the shares of Common Stock
deemed to have been issued or sold upon the declaration of such dividend or
the making of such other distribution or the date of the granting of such
right of subscription or purchase, as the case may be.

                                (ii)  Treasury Shares.  The number of shares
of Common Stock outstanding at any given time shall not include shares owned
or held by or for the account of the Company, and the disposition of any such
shares shall be considered an issue or sale of Common Stock.

                        (f)     All calculations under this Section 8 shall be
made to the nearest cent or the nearest 1/100th of a share, as the case may
be.

                        (g)     Whenever the Exercise Price is adjusted
pursuant to Section 8(c) above, the Holder, after receipt of the determination
by the Appraiser, shall have the right to select an additional appraiser
(which shall be a nationally recognized accounting firm), in which case the
adjustment shall be equal to the average of the adjustments recommended by
each of the Appraiser and such appraiser.  The Holder shall promptly mail or
cause to be mailed to the Company, a notice setting forth the Exercise Price
after such adjustment and setting forth a brief statement of the facts
requiring such adjustment.  Such adjustment shall become effective immediately
after the record date mentioned above.

                        (h)     If:

                                        (i)     the Company shall declare a
dividend (or any other distribution) on its Common Stock; or

                                        (ii)    the Company shall declare a
special nonrecurring cash dividend on or a redemption of its Common Stock; or

                                        (iii)   the Company shall authorize
the granting to all holders of the Common Stock rights or warrants to
subscribe for or purchase any shares of capital stock of any class or of any
rights; or

                                        (iv)    the approval of any
stockholders of the Company shall be required in connection with any
reclassification of the Common Stock, any consolidation or merger to which the
Company is a party, any sale or transfer of all or substantially all of the
assets of the Company, or any compulsory share exchange whereby the Common
Stock is converted into other securities, cash or property; or

                                        (v)     the Company shall authorize
the voluntary dissolution, liquidation or winding up of the affairs of the
Company,

then the Company shall cause to be mailed to each Holder at their last
addresses as they shall appear upon the Warrant Register, at least 20 calendar
days prior to the applicable record or effective date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose
of such dividend, distribution, redemption, rights or warrants, or if a record
is not to be taken, the date as of which the holders of Common Stock of record
to be entitled to such dividend, distributions, redemption, rights or warrants
are to be determined or (y) the date on which such reclassification,
consolidation, merger, sale, transfer or share exchange is expected to become
effective or close, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their shares of Common
Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up, provided, that the failure to mail
such notice or any defect therein or in the mailing thereof shall not affect
the validity of the corporate action required to be specified in such notice.

                9.      Payment of Exercise Price.  The Holder shall pay the
Exercise Price in one of the following manners:

                        (a)     Cash Exercise.  The Holder may deliver
immediately available funds; or

                        (b)     Cashless Exercise.  Commencing the earlier to
occur of the Effectiveness Date as defined in the Registration Rights
Agreement and the date the registration statement required to be filed
pursuant to the Registration Rights Agreement is declared effective by the
Securities and Exchange Commission, when a registration statement covering the
resale of the Warrant Shares and naming the Holder as a selling stockholder
thereunder is not then effective, the Holder may satisfy its obligation to pay
the Exercise Price through a "net" or "cashless" exercise, in which event the
Company shall issue to the Holder the number of Warrant Shares determined as
follows:

                                X = Y [(A-B)/A] where: X = the number of
Warrant Shares to be issued                           to the Holder.

                                Y = the number of Warrant Shares with respect
to which this Warrant is being exercised.

                                A = the average of the closing sale prices of
the Common Stock for the five (5) trading days immediately prior to (but not
including) the Date of Exercise.

                                B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have been
commenced, on the issue date.

                10.     Certain Exercise Restrictions.

                        A Holder may not exercise this Warrant to the extent
such exercise would result in the Holder, together with its affiliate,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon such exercise and held by such Holder after application of this Section.
To ensure compliance with this restriction, the Holder will be deemed to
represent to the Company each time that it delivers a Form of Election to
Purchase, that such Form of Election to Purchase has not violated the
restrictions set forth in this paragraph.  If the Holder has delivered a Form
of Election to Purchase for a number of Warrant Shares that, without regard to
any other shares that the Holder or its affiliates may beneficially own,
would result in the issuance in excess of the permitted amount hereunder, the
Company shall notify the Holder of this fact and shall honor the exercise for
the maximum portion of this Warrant permitted to be exercised on such Date of
Exercise in accordance with the periods described herein and, at the option of
the Holder, either keep the portion of the Warrant tendered for exercise in
excess of the permitted amount hereunder for future exercises or return such
excess portion of the Warrant to the Holder.  In the event of a merger or
consolidation of the Company with or into another Person, this paragraph shall
not apply with respect to a determination of the number of shares of common
stock issuable upon exercise in full of the Warrants if such determination is
necessary to establish the securities or other assets which the holders of
Common Stock shall be entitled to receive upon the effectiveness of such
merger or consolidation.

                11.     Fractional Shares.  The Company shall not be required
to issue or cause to be issued fractional Warrant Shares on the exercise of
this Warrant.  The number of full Warrant Shares which shall be issuable upon
the exercise of this Warrant shall be computed on the basis of the aggregate
