SECTION 2.	Exercise of Warrant.
2.1	  Procedure for Exercise of Warrant.
  To exercise this Warrant in whole or in part (but not as to any
fractional share of Common Stock), Holder shall deliver to Company at its
office referred to in Section 14 hereof at any time and from time to time
during the Term of this Warrant: (i) the Notice of Exercise in the form of
Exhibit A attached hereto, (ii) cash, certified or official bank check
payable to the order of Company, wire transfer of funds to Company's
account, or cancellation of any indebtedness of Company to Holder (or any
combination of any of the foregoing) in the amount of the Warrant Price for
each share being purchased, and (iii) this Warrant.  Notwithstanding any
provisions herein to the contrary, if the Current Market Price (as defined
in Section 6) is greater than the Warrant Price (at the date of
calculation, as set forth below), in lieu of exercising this Warrant as
hereinabove permitted, Holder may elect to receive shares of Common Stock
equal to the value (as determined below) of this Warrant (or the portion
thereof being canceled) by surrender of this Warrant at the office of
Company referred to in Section 14 hereof, together with the Notice of
Exercise, in which event Company shall issue to Holder that number of whole
shares of Common Stock computed using the following formula:
          CS = WCS x (CMP-WP)
- ----------------------------------------
                 CMP
Where
CS	equals the number of shares of Common Stock to be issued to
Holder
WCS	equals the number of shares of Common Stock purchasable under
the Warrant or, if only a portion of the Warrant is being
exercised, the portion of the Warrant being exercised (at the
date of such calculation)
CMP	equals the Current Market Price (at the date of such
calculation)
WP	equals the Warrant Price (as adjusted to the date of such
calculation)

In the event of any exercise of the rights represented by this Warrant, a
certificate or certificates for the shares of Common Stock so purchased,
registered in the name of Holder or such other name or names as may be
designated by Holder, shall be delivered to Holder hereof within a
reasonable time, not exceeding fifteen (15) days, after the rights
represented by this Warrant shall have been so exercised; and, unless this
Warrant has expired, a new Warrant representing the number of shares
(except a remaining fractional share), if any, with respect to which this
Warrant shall not then have been exercised shall also be issued to Holder
hereof within such time.  The person in whose name any certificate for
shares of Common Stock is issued upon exercise of this Warrant shall for
all purposes be deemed to have become the holder of record of such shares
on the date on which Holder shall have complied with the conditions for
exercise of this Warrant set forth above, irrespective of the date of
delivery of such certificate, except that, if the date of such compliance
is a date when the stock transfer books of Company are closed, such person
shall be deemed to have become the holder of such shares at the close of
business on the next succeeding date on which the stock transfer books are
open.
2.2	  Transfer Restriction Legend.
  Each certificate for Warrant Shares shall bear the following legend
(and any additional legend required by (i) any applicable state securities
laws and (ii) any securities exchange upon which such Warrant Shares may,
at the time of such exercise, be listed) on the face thereof unless at the
time of exercise such Warrant Shares shall be registered under the
Securities Act:
"The shares represented by this certificate have not been registered
under the Securities Act of 1933, as amended, and may not be sold or
transferred in the absence of such registration or an exemption
therefrom under said Act."
Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon
completion of a public distribution under a registration statement of the
securities represented thereby) shall also bear such legend unless, in the
opinion of counsel for Holder thereof (which counsel shall be reasonably
satisfactory to Company) the securities represented thereby are not, at
such time, required by law to bear such legend.
SECTION 3.	Covenants as to Common Stock.
  Company covenants and agrees that all shares of Common Stock that
may be issued upon the exercise of the rights represented by this Warrant
shall, upon issuance, be validly issued, fully paid and nonassessable, and
free from all taxes, liens and charges with respect to the issue thereof.
Company further covenants and agrees that it shall pay when due and payable
any and all federal and state taxes which may be payable in respect of the
issue of this Warrant or any Common Stock or certificates therefor issuable
upon the exercise of this Warrant.  Company further covenants and agrees
that Company shall at all times have authorized and reserved, free from
preemptive rights, a sufficient number of shares of Common Stock to provide
for the exercise of the rights represented by this Warrant.  Company
further covenants and agrees that if any shares of capital stock to be
reserved for the purpose of the issuance of shares upon the exercise of
this Warrant require registration with or approval of any governmental
authority under any federal or state law before such shares may be validly
issued or delivered upon exercise, then Company shall in good faith and as
expeditiously as possible endeavor to secure such registration or approval,
as the case may be.  If and so long as the Common Stock issuable upon the
exercise of this Warrant is listed on any national securities exchange,
Company shall, if permitted by the rules of such exchange, list and keep
listed on such exchange, upon official notice of issuance, all shares of
such Common Stock issuable upon exercise of this Warrant.

SECTION 5.	Adjustment of Number of Shares
..  Upon each adjustment of the Warrant Price as provided in
Section 6, Holder shall thereafter be entitled to purchase, at the Warrant
Price resulting from such adjustment, only the number of shares (calculated
to the nearest tenth of a share) obtained by multiplying the Warrant Price
in effect immediately prior to such adjustment by the number of shares
purchasable pursuant hereto immediately prior to such adjustment and
dividing the product thereof by the Warrant Price resulting from such
adjustment.
SECTION 6.	Adjustment of Warrant Price
..  The Warrant Price shall be subject to adjustment from time to time
as follows:
(i)	If Company shall at any time or from time to time during the
Term of this Warrant issue shares of Common Stock other than Excluded Stock
(as hereinafter defined) without consideration or for a consideration per
share less than the Warrant Price in effect immediately prior to the
issuance of such Common Stock, the Warrant Price in effect immediately
prior to each such issuance shall forthwith (except as provided in this
clause (i)) be adjusted to a price equal to the quotient obtained by
dividing:
(A) an amount equal to the sum of
(x) the total number of shares of Common Stock outstanding (including
any shares of Common Stock deemed to have been issued pursuant to
subdivision (3) of this clause (i) and to clause (ii) below)
immediately prior to such issuance multiplied by the Warrant Price in
effect immediately prior to such issuance, plus
(y) the consideration received by Company upon such issuance,
by
(B) the total number of shares of Common Stock outstanding (including
any shares of Common Stock deemed to have been issued pursuant to
subdivision (3) of this clause (i) and to clause (ii) below)
immediately after the issuance of such Common Stock.
For the purposes of any adjustment of the Warrant Price pursuant to
this clause (i), the following provisions shall be applicable:
1.	In the case of the issuance of Common Stock for cash, the
consideration shall be deemed to be the amount of cash paid
therefor after deducting therefrom any discounts, commissions
or other expenses allowed, paid or incurred by Company for any
underwriting or otherwise in connection with the issuance and
sale thereof.
2.	In the case of the issuance of Common Stock for a consideration
in whole or in part other than cash, the consideration other
than cash shall be deemed to be the fair market value thereof
as determined by the Board of Directors of Company,
irrespective of any accounting treatment; provided, however,
that such fair market value as determined by the Board of
Directors, together with any cash consideration being paid,
shall not exceed an aggregate amount equal to the product of
(i) the aggregate Current Market Price per share of Common
Stock as determined as provided in clause (vii) below,
multiplied by (ii) the number of shares of Common Stock being
issued in such issuance.
3.	In the case of the issuance of (i) options to purchase or
rights to subscribe for Common Stock, (ii) securities or
obligations by their terms convertible into or exchangeable for
Common Stock or (iii) options to purchase or rights to
subscribe for such convertible or exchangeable securities or
obligations:
(A)	the aggregate maximum number of shares of Common Stock
deliverable upon exercise of such options to purchase or
rights to subscribe for Common Stock shall be deemed to
have been issued at the time such options or rights were
issued and for a consideration equal to the consideration
(determined in the manner provided in subdivisions (1)
and (2) above with the proviso in subdivision (2) being
applied to the number of shares of Common Stock
deliverable upon such exercise), if any, received by
Company upon the issuance of such options or rights plus
the minimum purchase price provided in such options or
rights for the Common Stock covered thereby;
(B)	the aggregate maximum number of shares of Common Stock
deliverable upon conversion of or in exchange for any
such convertible or exchangeable securities or
obligations or upon the exercise of options to purchase
or rights to subscribe for such convertible or
exchangeable securities or obligations and subsequent
conversions or exchanges thereof shall be deemed to have
been issued at the time such securities or obligations
were issued or such options or rights were issued and for
a consideration equal to the consideration received by
Company for any such securities or obligations and
related options or rights (excluding any cash received on
account of accrued interest or accrued dividends), plus
the additional consideration, if any, to be received by
Company upon the conversion or exchange of such
securities or obligations or the exercise of any related
options or rights (the consideration in each case to be
determined in the manner provided in subdivisions (1) and
(2) above with the proviso in subdivision (2) being
applied to the number of shares of Common Stock
deliverable upon such conversion, exchange or exercise);
(C)	on any change in the number of shares of Common Stock
deliverable upon exercise of any such options or rights
or conversion of or exchange for such convertible or
exchangeable securities or obligations, other than a
change resulting from the antidilution provisions
thereof, the Warrant Price shall forthwith be readjusted
to such Warrant Price as would have obtained had the
adjustment made upon the issuance of such options, rights
or securities or obligations not converted prior to such
change or options or rights related to such securities or
obligations not converted prior to such change being made
upon the basis of such change; and
(D)	on the expiration of any such options or rights, the
termination of any such rights to convert or exchange or
the expiration of any options or rights related to such
convertible or exchangeable securities or obligations,
the Warrant Price shall forthwith be readjusted to such
Warrant Price as would have obtained had the adjustment
made upon the issuance of such options, rights,
securities or options or rights related to such
securities or obligations being made upon the basis of
the issuance of only the number of shares of Common Stock
actually issued upon the conversion or exchange of such
securities or obligations or upon the exercise of the
options or rights related to such securities or
obligations.  "Excluded Stock" shall mean shares of
Common Stock issued by Company (1) under any circumstance
for which an adjustment is provided in clauses (iii) or
(iv) of this Section 6 or in Section 8, and (2) in
connection with the issuance of Common Stock (including
any share of Common Stock deemed to have been issued
pursuant to subdivision (3) of clause (i) above)
(appropriately adjusted for stock splits and
combinations) to directors, officers, or employees of, or
consultants to, Company under any stock option or other
similar incentive plan approved by the Board of Directors
of Company as in effect on the date of this Warrant.
(ii)	"Excluded Stock" shall mean shares of Common Stock issued by
Company (1) under any circumstance for which an adjustment is provided in
clauses (iii) or (iv) of this Section 6 or in Section 8, and (2) in
connection with the issuance of Common Stock (including any share of Common
Stock deemed to have been issued pursuant to subdivision (3) of clause (i)
above) (appropriately adjusted for stock splits and combinations) to
directors, officers, or employees of, or consultants to, Company under any
stock option or other similar incentive plan approved by the Board of
Directors of Company as in effect on the date of this Warrant.
(iii)	If, at any time during the Term of this Warrant, the number of
shares of Common Stock outstanding is increased by a stock dividend payable
in shares of Common Stock or by a subdivision or split-up of shares of
Common Stock, then, following the record date fixed for the determination
of holders of Common Stock entitled to receive such stock dividend,
subdivision or split-up, the Warrant Price shall be appropriately decreased
so that the number of shares of Common Stock issuable upon the exercise
hereof shall be increased in proportion to such increase in outstanding
shares.
(iv)	If, at any time during the Term of this Warrant, the number of
shares of Common Stock outstanding is decreased by a combination of the
outstanding shares of Common Stock, then, following the record date for
such combination, the Warrant Price shall appropriately increase so that
the number of shares of Common Stock issuable upon the exercise hereof
shall be decreased in proportion to such decrease in outstanding shares.
(v)	In case, at any time during the Term of this Warrant, Company
shall declare a cash dividend upon its Common Stock payable otherwise than
out of earnings or earned surplus or shall distribute to holders of its
Common Stock shares of its capital stock (other than Common Stock), stock
or other securities of other persons, evidences of indebtedness issued by
Company or other persons, assets (excluding cash dividends and
distributions) or options or rights (excluding options to purchase and
rights to subscribe for Common Stock or other securities of Company
convertible into or exchangeable for Common Stock), then, in each such
case, immediately following the record date fixed for the determination of
the holders of Common Stock entitled to receive such dividend or
distribution, the Warrant Price in effect thereafter shall be determined by
multiplying the Warrant Price in effect immediately prior to such record
date by a fraction of which the numerator shall be an amount equal to the
difference of (x) the Current Market Price of one share of Common Stock
minus (y) the fair market value (as determined by the Board of Directors of
Company, whose determination shall be conclusive) of the amount of cash,
stock, securities, evidences of indebtedness, assets, options or rights, as
the case may be, so distributed in respect of one share of Common Stock,
and of which the denominator shall be such Current Market Price.
(vi)	All calculations under this Section 6 shall be made to the
nearest cent or to the nearest one-tenth (1/10) of a share, as the case may
be.
(vii)	For the purpose of any computation pursuant to this Section 6,
the Current Market Price at any date of one share of Common Stock shall be
deemed to be the average of the daily closing prices for the 15 consecutive
business days ending on the last business day before the day in question
(as adjusted for any stock dividend, split, combination or reclassification
that took effect during such 15 business day period).  The closing price
for each day shall be the last reported sales price regular way or, in case
no such reported sales took place on such day, the average of the last
reported bid and asked prices regular way, in either case on the principal
national securities exchange on which the Common Stock is listed or
admitted to trading or as reported by Nasdaq (or if the Common Stock is not
at the time listed or admitted for trading on any such exchange or if
prices of the Common Stock are not reported by Nasdaq then such price shall
be equal to the average of the last reported bid and asked prices on such
day as reported by The National Quotation Bureau Incorporated or any
similar reputable quotation and reporting service, if such quotation is not
reported by The National Quotation Bureau Incorporated); provided, however,
that if the Common Stock is not traded in such manner that the quotations
referred to in this clause (vii) are available for the period required
hereunder, the Current Market Price shall be determined in good faith by
the Board of Directors of Company or, if such determination cannot be made
or if Holder disputes in writing any determination so made by the Company's
Board of Directors within 30 days of being informed of such determination,
by a nationally recognized independent investment banking or accounting
firm selected by the Board of Directors of Company (or if such selection
cannot be made, by a nationally recognized independent investment banking
or accounting firm selected by the American Arbitration Association in
accordance with its rules).
(viii)	Whenever the Warrant Price shall be adjusted as provided in
this Section 6, Company shall prepare a statement showing the facts
requiring such adjustment and the Warrant Price that shall be in effect
after such adjustment.  Company shall cause a copy of such statement to be
sent by mail, first class postage prepaid, to each Holder at its, his or
her address appearing on Company's records.  Where appropriate, such copy
may be given in advance and may be included as part of the notice required
to be mailed under the provisions of clause (x) of this Section 6.
(ix)	Adjustments made pursuant to clauses (iii), (iv) and (v) above
shall be made on the date such dividend, subdivision, split-up, combination
or distribution, as the case may be, is made, and shall become effective at
the opening of business on the business day next following the record date
for the determination of stockholders entitled to such dividend,
subdivision, split-up, combination or distribution.
(x)	In the event Company shall propose to take any action of the
types described in clauses (iii), (iv), or (v) of this Section 6, Company
shall forward, at the same time and in the same manner, to Holder such
notice, if any, which Company shall give to the holders of capital stock of
Company.
(xi)	In any case in which the provisions of this Section 6 shall
require that an adjustment shall become effective immediately after a
record date for an event, Company may defer until the occurrence of such
event issuing to Holder of all or any part of this Warrant which is
exercised after such record date and before the occurrence of such event
the additional shares of capital stock issuable upon such exercise by
reason of the adjustment required by such event over and above the shares
of capital stock issuable upon such exercise before giving effect to such
adjustment exercise; provided, however, that Company shall deliver to such
Holder a due bill or other appropriate instrument evidencing such Holder's
right to receive such additional shares upon the occurrence of the event
requiring such adjustment.

SECTION 7.	Ownership.
7.1	  Ownership of This Warrant.
  Company may deem and treat the person in whose name this Warrant is
registered as the holder and owner hereof (notwithstanding any notations of
ownership or writing hereon made by anyone other than Company) for all
purposes and shall not be affected by any notice to the contrary until
presentation of this Warrant for registration of transfer as provided in
this Section 7.
7.2	  Transfer and Replacement.
  This Warrant and all rights hereunder are transferable in whole or
in part upon the books of Company by Holder hereof in person or by duly
authorized attorney, and a new Warrant or Warrants, of the same tenor as
this Warrant but registered in the name of the transferee or transferees
(and in the name of Holder, if a partial transfer is effected) shall be
made and delivered by Company upon surrender of this Warrant duly endorsed,
at the office of Company referred to in Section 14 hereof, together with a
properly executed Assignment (in the form of Exhibit B or Exhibit C hereto,
as the case may be).  Upon receipt by Company of evidence reasonably
satisfactory to it of the loss, theft or destruction, and, in such case, of
indemnity or security reasonably satisfactory to it, and upon surrender of
this Warrant if mutilated, Company shall make and deliver a new Warrant of
like tenor, in lieu of this Warrant.  This Warrant shall be promptly
cancelled by Company upon the surrender hereof in connection with any
transfer or replacement.  Except as otherwise provided above, in the case
of the loss, theft or destruction of a Warrant, Company shall pay all
expenses, taxes and other charges payable in connection with any transfer
or replacement of this Warrant, other than stock transfer taxes (if any)
payable in connection with a transfer of this Warrant, which shall be
payable by Holder.  Holder shall not transfer this Warrant and the rights
hereunder except in compliance with federal and state securities laws.
SECTION 8.	Mergers, Consolidation, Sales.
  In the case of any proposed consolidation or merger of Company with
another entity, or the proposed sale of all or substantially all of its
assets to another person or entity, or any proposed reorganization or
reclassification of the capital stock of Company, then, as a condition of
such consolidation, merger, sale, reorganization or reclassification,
Company shall give 30 days' prior written notice thereof to Holder hereof
and lawful and adequate provision shall be made whereby Holder shall
thereafter have the right to receive upon the basis and upon the terms and
conditions specified herein, in lieu of the shares of the Common Stock of
Company immediately theretofore purchasable hereunder, such shares of
stock, securities or assets as may (by virtue of such consolidation,
merger, sale, reorganization or reclassification) be issued or payable with
respect to or in exchange for the number of shares of such Common Stock
purchasable hereunder immediately before such consolidation, merger, sale,
reorganization or reclassification.  In any such case appropriate provision
shall be made with respect to the rights and interests of Holder to the end
that the provisions hereof shall thereafter be applicable as nearly as may
be practicable, in relation to any shares of stock, securities or assets
thereafter deliverable upon the exercise of this Warrant.
SECTION 9.	Notice of Dissolution or Liquidation.
  In case of any distribution of the assets of Company in dissolution
or liquidation (except under circumstances when the foregoing Section 8
shall be applicable), Company shall give notice thereof to Holder hereof
and shall make no distribution to shareholders until the expiration of
thirty (30) days from the date of mailing of the aforesaid notice and, in
any case, Holder hereof may exercise this Warrant within thirty (30) days
from the date of the giving of such notice, and all rights herein granted
not so exercised within such thirty-day period shall thereafter become null
and void.
SECTION 10.	Notice of Extraordinary Dividends.
  If the Board of Directors of Company shall declare any dividend or
other distribution on its Common Stock except out of earned surplus or by
way of a stock dividend payable in shares of its Common Stock, Company
shall mail notice thereof to Holder hereof not less than thirty (30) days
prior to the record date fixed for determining shareholders entitled to
participate in such dividend or other distribution, and Holder hereof shall
not participate in such dividend or other distribution unless this Warrant
is exercised prior to such record date.  The provisions of this Section 10
shall not apply to distributions made in connection with transactions
covered by Section 8.
SECTION 11.	Fractional Shares.
  Fractional shares shall not be issued upon the exercise of this
Warrant but in any case where Holder would, except for the provisions of
this Section 11, be entitled under the terms hereof to receive a fractional
share upon the complete exercise of this Warrant, Company shall, upon the
exercise of this Warrant for the largest number of whole shares then called
for, pay a sum in cash equal to the excess of the value of such fractional
share (determined in such reasonable manner as may be prescribed in good
faith by the Board of Directors of Company) over the Warrant Price for such
fractional share.
SECTION 12.	Special Arrangements of Company.
  Company covenants and agrees that during the Term of this Warrant,
unless otherwise approved by Holder:
12.1	  Shall Not Amend Certificate.
  Company shall not amend its certificate or articles, as the case
may be, of incorporation to eliminate as an authorized class of capital
stock that class denominated as "Common Stock" on the date hereof.
12.2	  Shall Bind Successors.
  This Warrant shall be binding upon any corporation or other person
or entity succeeding to Company by merger, consolidation or acquisition of
all or substantially all of Company's assets.
SECTION 13.	Registration.
  Company covenants and agrees that the shares of Common Stock
issuable upon the exercise of this Warrant shall be entitled to the
benefits of the registration rights set forth in Exhibit D attached hereto.
SECTION 14.	Notices.
  Any notice or other document required or permitted to be given or
delivered to Holder shall be delivered at, or sent by certified or
registered mail to, Holder at its address for notices set forth in the
Agreement or to such other address as shall have been furnished to Company
in writing by Holder.  Any notice or other document required or permitted
to be given or delivered to Company shall be delivered at, or sent by
certified or registered mail to, Company at its address for notices set
forth in the Agreement or to such other address as shall have been
furnished in writing to Holder by Company.  Any notice so addressed and
mailed by registered or certified mail shall be deemed to be given when so
mailed. Any notice so addressed and otherwise delivered shall be deemed to
be given when actually received by the addressee.
SECTION 15.	No Rights as Stockholder; Limitation of Liability.
  This Warrant shall not entitle Holder to any of the rights of a
shareholder of Company except upon exercise in accordance with the terms
hereof.  No provision hereof, in the absence of affirmative action by
Holder to purchase shares of Common Stock, and no mere enumeration herein
of the rights or privileges of Holder, shall give rise to any liability of
Holder for the Warrant Price hereunder or as a shareholder of Company,
whether such liability is asserted by Company or by creditors of Company.
SECTION 16.	Law Governing.
  THE VALIDITY, INTERPRETATION, AND ENFORCEMENT OF THIS WARRANT SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
CALIFORNIA WITHOUT GIVING EFFECT TO THE CONFLICT OF LAW PRINCIPLES THEREOF.
SECTION 17.	Amendments.
  This Warrant and any provision hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by both
parties (or any respective predecessor in interest thereof).  The headings
in this Warrant are for purposes of reference only and shall not affect the

EXHIBIT D
REGISTRATION RIGHTS
The Common Stock issuable upon exercise of the attached Warrant shall
be deemed "registrable securities" under, and Holder of the attached
Warrant shall otherwise be entitled to the benefit of, the following
agreement (the "Agreement") between Company and its investor(s):
None
[Identify Agreement by date, title and parties.]
Company agrees that no amendments shall be made to the Agreement
which would have an adverse impact on Holder's registration rights
thereunder without the consent of Holder.  By acceptance of the Warrant to
which this Exhibit D is attached, Holder shall be deemed to be a party to
the Agreement.
If no Agreement is identified above, then Holder shall be entitled to
the benefits of the following registration rights (hereinafter referred to
as the "Registration Rights") which shall be incorporated into and deemed
part of the attached Warrant; provided, that the Registration Rights
granted pursuant to Section 4 below shall be effective notwithstanding the
existence of non-existence of any Agreement:
1.	Certain Definitions.
  As used herein, the following terms shall have the following
respective meanings (any capitalized terms used in these Registration
Rights and not otherwise defined below to have the meanings ascribed to
them in the attached Warrant):
"Commission" shall mean the Securities and Exchange Commission or any
other federal agency at the time administering the Securities Act.
"Holder" shall mean any holder of Registrable Securities.
"Other Shareholders" shall mean holders of securities of Company who
are entitled by contract with Company or who are permitted by Company to
have securities included in a registration of Company's securities.
The terms "register," "registered" and "registration" shall refer to
a registration effected by preparing and filing a registration statement in
compliance with the Securities Act and applicable rules and regulations
thereunder, and the effectiveness of such registration statement.
"Registrable Securities" shall mean the Warrant Shares less any
Warrant Shares theretofore sold to the public or in a private placement.
"Registration Expenses" shall mean all expenses incurred by Company
in compliance with Section 2 and 4 hereof, including, without limitation,
all registration and filing fees, printing expenses, fees and disbursements
of counsel for Company, blue sky fees and expenses, and the expense of any
special audits incident to or required by any such registration (but
excluding the compensation of regular employees of Company, which shall be
paid in any event by Company).
2.	Company Registration.
(a)	Notice of Registration.  If Company shall determine to register
any of its Common Stock or securities convertible into or exchangeable or
exercisable for Common Stock either for its own account or for the account
of any Other Shareholder other than a registration relating solely to
employee benefit plans, or a registration relating solely to a Commission
Rule 145 transaction, or any other registration on any registration form
which does not permit secondary sales, Company shall:
(i)	promptly give to each Holder written notice thereof (which
shall include a list of the jurisdictions in which Company intends to
attempt to qualify such securities under the applicable blue sky or other
state securities laws); and
(ii)	include in such registration (and any related qualification
under blue sky laws or other compliance), and in any underwriting involved
therein, all the Registrable Securities specified in a written request or
requests, made by any Holder within fifteen (15) days after receipt of the
written notice from Company described in clause (i) above, subject to (a)
requirements and rights existing as of the date of this Warrant of Other
Shareholders, and (b) any limitations on the number of shares as set forth
in Section 2(b) below.
(b)	Underwriting.  If the registration of which Company gives notice
is for a registered public offering involving an underwriting, Company
shall so advise Holders as part of the written notice given pursuant to
Section 2(a)(i).  In such event, the right of any Holder to registration
pursuant to Section 2 shall be conditioned upon such Holder's participation
in such underwriting and the inclusion of such Holder's Registrable
Securities in the underwriting to the extent provided herein.  All Holders
proposing to distribute their securities through such underwriting shall
(together with Company, directors and officers and the Other Shareholders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter or
underwriters selected for underwriting by Company.
Notwithstanding any other provision of this Section 2, if the
underwriter determines that marketing or other factors require a limitation
on the number of shares to be underwritten, the underwriter may (subject to
the allocation priority set forth below) exclude from such registration and
underwriting some or all of the Registrable Securities which would
otherwise be underwritten pursuant hereto.  Company shall so advise all
holders of securities requesting registration, and the number of shares of
securities that are entitled to be included in the registration and
underwriting shall be allocated in the following manner.  The number of
shares that may be included in the registration and underwriting on behalf
of such Holders, directors and officers and Other Shareholders (if any)
shall be allocated among such Holders, directors and officers and Other
Shareholders in proportion, as nearly as practicable, to the respective
amounts of Registrable Securities and other securities which they had
requested to be included in such registration at the time of filing the
registration statement.
If any Holder of Registrable Securities or any officer, director or
Other Shareholder disapproves of the terms of any such underwriting, it, he
or she may elect to withdraw therefrom by written notice to Company and the
underwriter.  Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration.
3.	Registration Rights.
  In the event that Company grants after the date hereof registration
rights, including demand registration rights, to any other holder of
securities of Company, Company shall promptly give to Holder written notice
thereof and, if in the opinion of Holder such registration rights are more
favorable than the registration rights provided under the attached Warrant,
Holder shall so notify Company within thirty (30) days of receipt of the
foregoing notice from Company.  Holder shall have the right, upon notice to
Company after receipt of the Company's notice to Holder as set forth
immediately above, to deem such registration rights to be incorporated into
the attached Warrant, whereupon such registration rights shall
automatically be deemed to be incorporated in the attached Warrant.
4.	Demand Registration Rights.  After receipt of a written request
from a Holder representing at least an aggregate of twenty percent (20%) of
the total of all Warrant Shares then subject to purchase upon exercise of
the Warrant, requesting that the Company register Warrant Shares issuable
upon Holder's exercise of the Warrant or any of the Warrant Shares under
the Securities Act and specifying the intended method or methods of
disposition thereof, the Company shall promptly notify all Holders of
Warrants or Warrant Shares in writing of the receipt of such request and
each such Holder may elect, by written notice to the Company within fifteen
(15) business days from the date of such Holders's receipt of the Company's
notice, to have its Warrant Shares included in such registration.  The
Company shall, as expeditiously as possible following such request, use its
best efforts to effect the registration under the Securities Act of all
Warrant Shares which the Company has been requested to register by Holder
for sale, all to the extent requested to permit the disposition (in
accordance with the intended method or methods thereof, as aforesaid) of
the Warrant Shares so registered; provided, that the Company shall not be
required to effect more than three (3) registrations of any Warrant Shares
pursuant to this Section 4, not including registration statements on Form
S-3 which shall not count for purposes of this limitation.  No holder of
any other warrant issued after the date of this Warrant shall receive or be
entitled to receive registration rights that are more favorable than the
registration rights available to Holder pursuant to this Section 4.
5.	Expenses of Registration.
  Company (or Other Shareholders) shall bear all Registration
Expenses incurred in connection with any registration, qualification and
compliance by Company (or such Other Shareholders) pursuant to Sections 2
and 4.   .
6.	Registration Procedures.
  In the case of each registration effected by Company pursuant to
these Registration Rights, Company shall keep each Holder advised in
writing as to the initiation of each registration and as to the completion
thereof.  Company shall, at its expense:
(i)	keep such registration effective for a period of one hundred
twenty (120) days or until Holder or Holders have completed the
distribution described in the registration statement relating thereto,
whichever first occurs;
(ii)	furnish such number of prospectuses and other documents
incident thereto as a Holder from time to time may reasonably request; and
(iii)	use its best efforts to register or qualify the Registrable
Securities under the securities laws or blue-sky laws of such jurisdictions
as any Holder may request; provided, however, that Company shall not be
obligated to register or qualify such Registrable Securities in any
particular jurisdiction in which Company would be required to execute a
general consent to service of process in order to effect such registration,
qualification or compliance, unless Company is already subject to service
in such jurisdiction and except as may be required by the Securities Act or
applicable rules or regulations thereunder.
7.	Indemnification.
(i)	Company, with respect to each registration, qualification and
compliance effected pursuant to these Registration Rights, shall indemnify
and hold harmless each Holder, each of its officers, directors, partners,
and agents, and each party controlling such Holder, and each underwriter,
if any, and each party who controls any underwriter, against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out
of or based on any untrue statement (or alleged untrue statement) of a
material fact contained in any prospectus, offering circular or other
document (including any related registration statement, notification or the
like) incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material
fact required to be stated therein or necessary to make the statements
therein not misleading, or any violation by Company of the Securities Act
or any rule or regulation thereunder applicable to Company and relating to
action or inaction required of Company in connection with any such
registration, qualification or compliance, and shall reimburse each such
Holder, each of its officers, directors, partners, and agents, and each
party controlling such Holder, each such underwriter and each party who
controls any such underwriter, for any legal and any other expenses
incurred in connection with investigating or defending any such claim,
loss, damage, liability or action, provided that Company shall not be
liable in any such case to the extent that any such claim, loss, damage,
liability or expense arises out of or is based on any untrue statement or
omission based solely upon written information furnished to Company by such
Holder or underwriter, as the case may be, and stated to be specifically
for use in any prospectus, offering circular or other document (including
any related registration statement, notification or the like) incident to
any such registration, qualification or compliance.
(ii)	Each Holder shall, if Registrable Securities held by it, him or
her are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify and hold harmless
Company, each of its directors and officers and each underwriter, if any,
of Company's securities covered by such a registration statement and each
party who controls Company or such underwriter against all claims, losses,
damages and liabilities (or actions in respect thereof) arising out of or
based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement, prospectus, offering
circular or other document, or any omission (or alleged omission) to state
therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and shall reimburse Company and such
directors, officers, partners, agents, parties, underwriters or control
persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or
alleged omission) is made in such registration statement, prospectus,
offering circular or other document solely in reliance upon and in
conformity with written information furnished to Company by such Holder and
stated to be specifically for use in any prospectus, offering circular or
other document (including any related registration statement, notification
or the like) incident to any such registration, qualification or
compliance; provided, however, that the obligations of such Holder
hereunder shall be limited to an amount equal to the proceeds to each such
Holder of securities sold as contemplated herein.
(iii)	Each party entitled to indemnification under this Section 6
(the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity
may be sought, and shall permit the Indemnifying Party to assume the
defense of any such claim or any litigation resulting therefrom, provided
that counsel for the Indemnifying Party, who shall conduct the defense of
such claim or any litigation resulting therefrom, shall be approved by the
Indemnified Party (whose approval shall not unreasonably be withheld), and
the Indemnified Party may participate in such defense at such party's
expense (unless the Indemnified Party shall have been advised by counsel
that actual or potential differing interests or defenses exist or may exist
between the Indemnifying Party and the Indemnified Party, in which case
such expense shall be paid by the Indemnifying Party), and provided further
that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under these
Registration Rights.  No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified
Party, consent to entry of any judgment or enter into any settlement which
does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation.  Each Indemnified Party
shall provide such information as may be reasonably requested by an
Indemnifying Party in order to enable such Indemnifying Party to defend a
claim as to which indemnity is sought.
8.	Information by Holder.
  Each Holder shall furnish to Company such information regarding
such Holder as Company may reasonably request in writing and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to in these Registration Rights.
9.	Rule 144 Reporting.
  With a view to making available the benefits of certain rules and
regulations of the Commission which may permit the sale of the Registrable
Securities to the public without registration, Company agrees to:
(i)	Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times
that Holder holds Registrable Securities from and after ninety (90) days
following the effective date of the first registration under the Securities
Act filed by Company for an offering of its securities to the general
public;
(ii)	File with the Commission in a timely manner all reports and
other documents required of Company under the Exchange Act at any time
after it has become subject to such reporting requirements; and
(iii)	So long as Holder owns any Registrable Securities, furnish to
Holder forthwith upon request a written statement by Company as to its
compliance with the reporting requirements of Rule 144 (at any time from
and after the end of the ninety (90) day period referred to in clause (i)),
and of the Securities Act and the Exchange Act (at any time after it has
become subject to such reporting requirements), a copy of the most recent
annual or quarterly report of Company, and such other reports and documents
so filed as Holder may reasonably request in availing itself of any rule or
regulation of the Commission allowing Holder to sell any such securities
without registration.
