                          THE QUARTZ GROUP, INC.
          (Incorporated under the laws of the State of Colorado)

                       COMMON STOCK PURCHASE WARRANT
                      252,500 SHARES OF COMMON STOCK

           Void After December 31, 2001  (the "Expiration Date")
- ----------------------------------------------------------------------------

  This is to certify that, for value received, receipt of which is hereby
acknowledged, DARYL SILVERSPARRE, 3649 El Caminito Street, La Crescenta, CA
91214 (hereinafter called the "holder"), is entitled to purchase from THE
QUARTZ GROUP, INC., a Colorado corporation (hereinafter called the "Company"),
at the Warrant Price of ONE CENTS ($0.01) per share, subject to adjustment as
hereinafter provided (hereinafter called the "Warrant Price"), at any time on
or before 5:00 P.M. local Denver, Colorado time on December 31, 2001 (the
"Expiration Date"), up to TWO HUNDRED FIFTY TWO THOUSAND FIVE HUNDRED
(252,500) fully paid and non-assessable shares of Common Stock of the Company
(hereinafter called "Common Stock"), subject to the terms and conditions
hereof.

  This Warrant was originally issued in 1997 as part of Common Stock
Purchase Warrants (the "Warrants") issued in consideration of certain
consulting services rendered to the Company.   This Warrant represents part of
such issue of Common Stock Purchase Warrants and is herein called "this
Warrant."  THIS WARRANT HAS BEEN PLEDGED WITH THE COMPANY AS COLLATERAL
SECURITY FOR PAYMENT OF A NON-TRANSFERABLE NOTE GIVEN TO THE COMPANY IN
PAYMENT OF THE PURCHASE PRICE FOR THE ISSUANCE OF THIS WARRANT, AND THE
EXERCISE OF THIS WARRANT SHALL BE CONDITIONED UPON THE PAYMENT OF SAID NON-
TRANSFERABLE NOTE IN ACCORDANCE WITH ITS TERMS.

  This Warrant may be exercised by the holder as hereinabove provided as
to the whole or any part of the shares of Common Stock covered hereby, by
surrender of this Warrant at the principal office of any transfer agent for
the Common Stock, or, if the Company shall not have any transfer agent for the
Common Stock, at the principal office of the Company (any such transfer agent,
or the Company acting hereunder, being hereinafter called the "Warrant
Agent"), with the statement of election to subscribe attached hereto duly
executed and upon payment to the Company of the Warrant Price for shares so
purchased in cash or by certified check or bank draft.  Thereupon (except that
if, upon such date, the stock transfer books of the Company shall be closed,
then upon the next succeeding date on which such transfer books are open),
this Warrant shall be deemed to have been exercised and the person exercising
the same to have become a holder of record of shares of Common Stock (or of
the other securities or property to which such person is entitled upon such
exercise) purchased hereunder for all purposes, and certificates for such
shares so purchased shall be delivered to the purchaser within a reasonable
time (not exceeding five business days, except while the transfer books of the
Company are closed) after this Warrant shall have been exercised as set forth
hereinabove.  If this Warrant shall be exercised in respect of a part only of
the shares of Common Stock covered hereby, the holder shall be entitled to
receive a similar warrant of like tenor and date covering the number of shares
in respect of which this Warrant shall not have been exercised.

  The Company covenants and agrees that all shares which may be issued
upon the exercise of the rights represented by this Warrant will, upon
issuance, be validly issued, fully paid and non-assessable and free from all
taxes, liens and charges with respect to the issue thereof (other than taxes
in respect of any transfer occurring contemporaneously with such issue).  The
Company further covenants and agrees that, during the period within which the
rights represented by this Warrant may be exercised, the Company will at all
times have authorized and reserved a sufficient number of shares of Common
Stock to provide for the exercise of the rights represented by this Warrant.

  The rights of the holder of this Warrant shall be subject to the
following terms and conditions:

SECTION 1.   CERTAIN ADJUSTMENTS AND NOTICES

  1.1.  In case the Company shall hereafter at any time change as a whole,
by split-up, subdivision or combination in any manner or by the making of a
stock dividend, the number of outstanding shares of Common Stock into a
different number of shares of Common Stock with or without par value, (i) the
number of shares of Common Stock which immediately prior to such change the
holder of this Warrant shall have been entitled to purchase pursuant to this
Warrant shall be increased or decreased in direct proportion to the increase
or decrease, respectively, in the number of shares of Common Stock outstanding
immediately prior to such change, and (ii) the Warrant Price in effect
immediately prior to such change shall be increased or decreased, as the case
may be, in inverse proportion to such increase or decrease in the number of
such shares outstanding immediately prior to such change; in any such event,
the rights of the holder of this Warrant to an adjustment in the number of
shares of Common Stock purchasable on exercise of this Warrant as herein
provided shall continue and be preserved in respect of any shares, securities,
or assets which the holder of this Warrant becomes entitled to purchase
hereafter.

  1.2.  In case of any capital reorganization or any reclassification of
the capital stock of the Company or in case of the consolidation or merger of
the Company with another corporation, or in case of any sale, transfer or
other disposition to another corporation of all or substantially all the
property, assets, business and goodwill of the Company as an entirety, as the
case may be, the holder of this Warrant shall thereafter be entitled to
purchase (and it shall be a condition to the consummation of any such
reorganization, reclassification, consolidation, merger, sale, transfer or
other disposition, that appropriate provision shall be made so that such
holder shall thereafter be entitled to purchase) the kind and amount of shares
of stock and other securities and property receivable, upon such capital
reorganization, reclassification of capital stock, consideration, merger,
sale, transfer or other disposition, by a holder of the number of shares of
Common Stock which this Warrant entitled the holder thereof to purchase
immediately prior to such capital reorganization, reclassification of capital
stock, consolidation, merger, sale, transfer or other disposition; and in any
such case appropriate adjustments (as determined in good faith by the Board of
Directors of the Company or of such other corporation, as the case may be)
shall be made in the application of the provisions herein set forth with
respect to rights and interests thereafter of the holder of this Warrant, to
the end that the provisions set forth herein (including the specified changes
in and other adjustments of the Warrant Price) shall thereafter be applicable,
as near as reasonably may be, in relation to any shares or other property
thereafter purchasable upon the exercise of this Warrant.

  1.3.  In case the Company shall hereafter at any time declare a dividend
upon shares of Common Stock payable otherwise than out of retained earnings or
otherwise than in shares of Common Stock or in stock or obligations directly
or indirectly convertible into or exchangeable for Common Stock, the holder of
this Warrant shall, upon exercise of this Warrant in whole or in part, be
entitled to receive, in addition to the number of shares of Common Stock
deliverable upon such exercise against payment of the Warrant Price therefor,
but without further consideration, the cash, stock or other securities or
property which the holder of this Warrant would have received as dividends
(otherwise than out of such retained earnings and otherwise than in shares of
Common Stock or in such convertible or exchangeable stock or obligations) if
continuously since the date set forth at the foot of this Warrant such holder
(i) had been the holder of record of the number of shares of Common Stock
deliverable upon such exercise and (ii)
Common Stock Purchase Warrants                                    Page 3

had retained all dividends in stock or other securities (other than shares of
Common Stock or such convertible or exchangeable stock or obligations) paid or
payable in respect of said number of shares of Common Stock or in respect of
any such stock or other securities so paid or payable as such dividends.  For
purposes of this Section 1.3, a dividend payable otherwise than in cash shall
be considered to be payable out of retained earnings only to the extent of the
fair value of such dividend as determined by the Board of Directors of the
Company.

  1.4.  No certificates for fractional shares of Common Stock shall be
issued upon the exercise of this Warrant, but in lieu thereof the Company
shall, upon exercise in full of this Warrant, purchase out of funds legally
available therefor any such fractional interest for an amount in cash equal to
the current market value of such fractional interest calculated to the nearest
cent, computed on the basis of the closing sale price, as reported by the
National Quotation Bureau, of the Common Stock in the over-the-counter market
on the most recent day within ten days prior to the date of such exercise for
which such closing prices shall have been so reported, or, if the Common Stock
is listed on a stock exchange registered with the Securities and Exchange
Commission or traded on the NASDAQ Stock Market, the last reported sale price
on such day; and if there shall have been no sale on said day, then the
computation shall be made on the basis of the last reported sale price within
ten days prior to such date.  If there have been no reported closing sale
prices, as the case may be, within such ten days, the current market value
shall be fixed in a manner determined in good faith by the Board of Directors
of the Company.

  1.5.  Whenever the Warrant Price is adjusted, as herein provided, the
Company shall forthwith file with the Warrant Agent a statement signed by the
President or any one of the Vice Presidents of the Company and by its
Treasurer or an Assistant Treasurer, stating the adjusted Warrant Price
determined as herein provided.  Such statement shall show in detail the facts
requiring such adjustment, including a statement of the consideration received
by the Company for any additional securities issued.  Whenever the Warrant
Price is adjusted, the Company will forthwith cause a notice stating the
adjustment and the Warrant Price to be mailed to the registered holder of this
Warrant at the address of such holder shown on the books of the Company.

SECTION 2.    INVESTMENT INTENT

  2.1   The holder of this Warrant, by acceptance hereof, acknowledges
that this Warrant and shares of the Company's Common Stock issuable upon
exercise hereof have not been registered under the Securities Act of 1933.  
Upon any exercise of this Warrant, the holder of this Warrant represents and
warrants that it will provide the Company with a written investment intent
letter by which the holder represents and warrants it is acquiring Common
Stock issuable on exercise for his or her own account for investment only and
without a view to the resale or other distribution thereof.

  2.2.  Before any transfer of this Warrant or the Common Stock issuable
upon exercise hereof shall be processed by the Company, the holder of this
Warrant agrees to give written notice to the Company before exercising or
selling such securities of such holder's intention to do so, describing
briefly the manner of any proposed sale of this Warrant or such holder's
intention as to the disposition to be made of shares of Common Stock issuable
upon such proposed exercise hereof.  Promptly upon receiving such written
notice, the Company shall present copies thereof to counsel for the Company
for such counsel's opinion.  If in the opinion of such counsel the proposed
exercise or sale may be effected without registration under the Securities Act
of 1933 of this Warrant or the shares of Common Stock issuable on the exercise
hereof, the Company, as promptly as practicable, shall notify such holder of
such opinion, whereupon such holder shall be entitled to sell this Warrant, or
to exercise this Warrant in accordance with its terms and dispose of the
shares received upon such exercise, all in accordance with the terms of the
notice delivered by such holder to the Company.  If in the opinion of such
counsel the proposed exercise or sale described in said written notice given
by the holder of this Warrant may not be effected without registration of this
Warrant or the shares of Common Stock issuable on the exercise hereof, the
Company shall promptly give written notice of

Common Stock Purchase Warrants                                    Page 4

such opinion to the holder of this Warrant.  The holder of this Warrant agrees
that, if the proposed exercise or sale by such holder cannot, in the opinion
of such counsel, be effected without such registration, the holder will not so
exercise or sell this Warrant or the shares of Common Stock issuable upon the
exercise hereof except in a transaction which in the opinion of counsel for
the Company has adequate representations and warranties for such transaction
to be exempt from the registration requirements of the Securities Act of 1993.

Section 3.     Miscellaneous

  3.1.  The issue of any stock or other certificate upon the exercise of
this Warrant shall be made without charge to the registered holder hereof for
any tax in respect of the issue of such certificate.  The Company shall not,
however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of any certificate in a name other
than that of the registered holder of this Warrant, and the Company shall not
be required to issue or deliver any such certificate unless and until the
person or persons requesting the issue thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the
Company that such tax has been paid.

  3.2.  This Warrant and all rights hereunder or any portion thereof are
transferable on the books of the Company, upon surrender of this Warrant, with
the form of assignment attached hereto duly executed by the registered holder
hereof or by his attorney duly authorized in writing, to the Warrant agent at
its principal office hereinabove referred to, and thereupon there shall be
issued in the name of the transferee or transferees, in exchange for this
Warrant, a new Warrant or Warrants of like tenor and date, representing in the
aggregate the right to subscribe for and purchase the number of shares, or
such portion thereof as shall be so transferred, which may be subscribed for
and purchased hereunder and if there shall be any balance of such shares not
so transferred, there shall be issued in the name of the registered holder of
this Warrant, a new Warrant or Warrants of like tenor and date representing in
the aggregate the right to subscribe for and purchase the balance of the
number of shares which may be subscribed for and purchased hereunder.

  3.3.  If this Warrant shall be lost, stolen, mutilated or destroyed, the
Company may instruct the Warrant Agent, on such terms as to indemnify or
otherwise as the Company may in its discretion impose, to issue a new Warrant
of like denomination, tenor and date as the Warrant so lost, stolen, mutilated
or destroyed.  Any such new Warrant shall constitute an original contractual
obligation of the Company, whether or not the allegedly lost, stolen,
mutilated or destroyed Warrant shall be at any time enforceable by anyone.

  3.4.  The Company and any Warrant Agent may deem and treat the
registered holder of this Warrant as the absolute owner of this Warrant for
all purposes and shall not be affected by any notice to the contrary.

  3.5.  This Warrant shall not entitle the holder to any rights of a
stockholder of the Company, either at law or in equity, including, without
limitation, the right to vote, to receive dividends and other distributions,
to exercise any preemptive rights or to receive any notice of meetings of
stockholders or of any other proceedings of the Company.

  3.6.  This Warrant shall be governed by the laws of the State of
Colorado.
