                          COMMON STOCK PURCHASE WARRANT

                              ARBIOS SYSTEMS, INC.

         THIS  CERTIFIES  that  for good and  valuable  consideration  received,
_________________________  or a registered  assignee (the "Holder") is entitled,
upon the terms and subject to the conditions  hereinafter  set forth, to acquire
from Arbios  Systems,  Inc., a Nevada  corporation  formerly known as Historical
Autographs U.S.A., Inc. (the "Corporation"),  up to  ____________________  fully
paid and  nonassessable  shares  of  common  stock,  par  value  $0.001,  of the
Corporation  ("Warrant  Stock")  at a purchase  price per share  (the  "Exercise
Price") of $2.50 (the "Warrant").

         THIS WARRANT IS ISSUED TO HOLDER IN  CONNECTION  WITH THE AGREEMENT AND
PLAN OF  REORGANIZATION BY AND AMONG THE CORPORATION,  HAUSA  ACQUISTION,  INC.,
ARBIOS   TECHNOLOGIES,   INC.,   AND  OTHERS,   DATED   OCTOBER  20,  2003  (THE
"REORGANIZATION  AGREEMENT").  PURSUANT TO THE  REORGANIZATION  AGREEMENT,  THIS
WARRANT REPLACES A COMMON STOCK PURCHASE WARRANT  PREVIOUSLY  ISSUED OR ISSUABLE
TO HOLDER BY ARBIOS TECHNOLOGIES, INC.

1.       Term of Warrant.

         Subject to the terms and  conditions  set forth  herein,  this  Warrant
shall be  exercisable,  in whole  or in part,  at any time on or after  the date
hereof and at or prior to 11:59 p.m., Pacific Standard Time, on October 29, 2006
(the "Expiration Time").  Notwithstanding  the foregoing,  the Corporation shall
have the right  (the  "Call  Right"),  except as may be  limited  by law,  other
agreements  or herein,  to  repurchase  and cancel  this  Warrant if the average
closing price for the  Corporation's  common  stock,  as quoted on the principal
trading  system on which the common  stock is listed  (such as the OTC  Bulletin
Board,  The  Nasdaq  Stock  Market,  any stock  exchange,  or other  established
over-the-counter  quotation  service),  is equal to or  greater  than  $4.00 per
share,  as  adjusted  pursuant  to Section  11 hereof,  during the period of the
twenty (20) consecutive  trading days prior to the date on which the Corporation
elects  to  exercise  the Call  Right.  The price at which  the  Corporation  is
entitled to exercise the Call Right (the  "Repurchase  Price") shall be equal to
the multiple of (i) $0.01 times (ii) the number of shares of Warrant  Stock that
this  Warrant is then  entitled to purchase.  In the event that the  Corporation
exercises its Call Right,  the Corporation  shall send the Holder written notice
of the exercise of the Call Right 20 calendar days before the repurchase becomes
effective.  The Holder shall have the right to exercise  this Warrant  until the
close of  business  on the  twentieth  (20th) day after the  mailing of the Call
Right  notice.  If this Warrant is not  exercised  during the  foregoing  20-day
period,   this  Warrant  shall  expire  and  cease  to  be  exercisable  on  the
twenty-first  (21st) day after the date of mailing of the notice.  Within  three
business  days after the  expiration of this Warrant as a result of the exercise
of the Call  Right,  the  Corporation  shall  mail to the  Holder a check in the
amount of the Repurchase Price.

2.       Exercise of Warrant.

         The purchase rights  represented by this Warrant are exercisable by the
registered Holder hereof, in whole or in part, at any time and from time to time
at or prior to the  Expiration  Time by the  surrender  of this  Warrant and the
Notice of  Exercise  form  attached  hereto  duly  executed to the office of the
Corporation at Cedars-Sinai Medical Center Research Building,  Suite D-4018, 110
George Burns Road, Los Angeles, California 90048 (or such other office or agency
of the  Corporation  as it may designate by notice in writing to the  registered
Holder  hereof  at the  address  of such  Holder  appearing  on the books of the
Corporation),  and upon  payment of the  Exercise  Price for the shares  thereby
purchased  (by  cash or by  check  or bank  draft  payable  to the  order of the
Corporation or by  cancellation of indebtedness of the Corporation to the Holder
hereof, if any, at the time of exercise in an amount equal to the purchase price
of the shares thereby purchased);  whereupon the Holder of this Warrant shall be
entitled to receive  from the  Corporation  a stock  certificate  in proper form
representing the number of shares of Warrant Stock so purchased.

3.       Issuance of Shares; No Fractional Shares of Scrip.

         Certificates for shares  purchased  hereunder shall be delivered to the
Holder hereof by the Corporation's  transfer agent at the Corporation's  expense
within a reasonable  time after the date on which this  Warrant  shall have been
exercised in accordance  with the terms hereof.  Each  certificate  so delivered
shall be in such  denominations  as may be  requested  by the Holder  hereof and
shall be registered in the name of such Holder or,  subject to applicable  laws,
such other name as shall be requested by the Holder.  If, upon  exercise of this
Warrant, fewer than all of the shares of Warrant Stock evidenced by this Warrant
are  purchased  prior  to  the  Expiration   Time,  one  or  more  new  warrants
substantially  in the form of, and on the terms in, this  Warrant will be issued
for the remaining  number of shares of Warrant Stock not purchased upon exercise
of this Warrant.  The Corporation hereby represents and warrants that all shares
of Warrant  Stock which may be issued upon the  exercise of this  Warrant  will,
upon such exercise,  be duly and validly  authorized and issued,  fully paid and
nonassessable  and free from all  taxes,  liens and  charges  in  respect of the
issuance  thereof  (other than liens or charges  created by or imposed  upon the
Holder of the Warrant Stock).  The Corporation  agrees that the shares so issued
shall be and will be deemed to be issued to such  Holder as the record  owner of
such shares as of the close of business on the date on which this Warrant  shall
have been  surrendered  for exercise in  accordance  with the terms  hereof.  No
fractional shares or scrip  representing  fractional shares shall be issued upon
the exercise of this Warrant. With respect to any fraction of a share called for
upon the exercise of this Warrant,  an amount equal to such fraction  multiplied
by the then current price at which each share may be purchased  hereunder  shall
be paid in cash to the Holder of this Warrant.

4.       Registration Rights.

         Pursuant  to the  terms of the  Subscription  Agreement  and  Exhibit A
thereto signed in conjunction  with this Warrant,  certain  registration  rights
apply to the Warrant  Stock if (i) the last  reported  sales price of the common
stock of the Corporation,  as published by the principal trading market on which
such  common  stock is then  quoted,  has  exceeded  two dollars and fifty cents
($2.50) for twenty (20)  consecutive  trading days or (ii) if the Corporation is
eligible to file a  registration  statement on Form S-3 with the  Securities and
Exchange Commission.  See the Subscription Agreement and Exhibit A thereto for a
full description of the registration  rights applicable to the Warrant Stock and
the limitations on such rights.

5.       Charges, Taxes and Expenses.

         Issuance of certificates  for shares of Warrant Stock upon the exercise
of this Warrant shall be made without  charge to the Holder hereof for any issue
or transfer tax or other  incidental  expense in respect of the issuance of such
certificate,  all of which taxes and expenses shall be paid by the  Corporation,
and such certificates  shall be issued in the name of the Holder of this Warrant
or in such  name or names as may be  directed  by the  Holder  of this  Warrant;
provided,  however,  that in the event  certificates for shares of Warrant Stock
are to be issued in a name other  than the name of the  Holder of this  Warrant,
this Warrant when surrendered for exercise shall be accompanied by an Assignment
Form to be provided by the Corporation duly executed by the Holder hereof.

6.       No Rights as Stockholders.

         This Warrant does not entitle the Holder hereof to any voting rights or
other rights as a stockholder of the Corporation prior to the exercise hereof.

7.       Exchange and Registry of Warrant.

         This  Warrant  is  exchangeable,  upon  the  surrender  hereof  by  the
registered  Holder at the above mentioned  office or agency of the  Corporation,
for a new Warrant of like tenor and dated as of such exchange.  The  Corporation
shall maintain at the  above-mentioned  office or agency a registry  showing the
name and address of the registered  Holder of this Warrant.  This Warrant may be
surrendered for exchange, transfer or exercise, in accordance with its terms, at
such office or agency of the Corporation,  and the Corporation shall be entitled
to rely in all  respects,  prior to written  notice to the  contrary,  upon such
registry.

8.       Loss, Theft, Destruction or Mutilation of Warrant.

         Upon receipt by the Corporation of evidence reasonably  satisfactory to
it of the loss, theft,  destruction or mutilation of this Warrant and in case of
loss, theft or destruction of indemnity or security  reasonably  satisfactory to
it,  and  upon  reimbursement  to the  Corporation  of all  reasonable  expenses
incidental  thereto,  and upon surrender and  cancellation  of this Warrant,  if
mutilated, the Corporation will make and deliver a new Warrant of like tenor and
dated as of such cancellation, in lieu of this Warrant.

9.       Saturdays, Sundays and Holidays.

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

10.      Merger, Sale of Assets, Etc.

         If at any time the Corporation proposes to merge or consolidate with or
into any other corporation, effect any reorganization,  or sell or convey all or
substantially  all of its assets to any other  entity,  then,  as a condition of
such reorganization,  consolidation, merger, sale or conveyance, the Corporation
or its successor,  as the case may be, shall enter into a supplemental agreement
to make lawful and adequate provision whereby the Holder shall have the right to
receive,  upon exercise of the Warrant, the kind and amount of equity securities
which would have been received upon such reorganization,  consolidation, merger,
sale or  conveyance  by a Holder of a number of shares of common  stock equal to
the number of shares issuable upon exercise of the Warrant  immediately prior to
such reorganization,  consolidation, merger, sale or conveyance. If the property
to  be  received  upon  such  reorganization,  consolidation,  merger,  sale  or
conveyance is not equity  securities,  the Corporation  shall give the Holder of
this  Warrant  ten (10)  business  days  prior  written  notice of the  proposed
effective date of such  transaction,  and if this Warrant has not been exercised
by or on the effective date of such transaction, it shall terminate.

11.      Subdivision, Combination, Reclassification, Conversion, Etc.

         If the  Corporation  at any  time  shall by  subdivision,  combination,
reclassification  of securities or otherwise,  change the Warrant Stock into the
same or a different  number of securities of any class or classes,  this Warrant
shall  thereafter  entitle  the  Holder  to  acquire  such  number  and  kind of
securities as would have been issuable in respect of the Warrant Stock (or other
securities  which  were  subject  to the  purchase  rights  under  this  Warrant
immediately prior to such subdivision,  combination,  reclassification  or other
change) as the result of such change if this Warrant had been  exercised in full
for cash immediately prior to such change. The Exercise Price hereunder shall be
adjusted if and to the extent  necessary to reflect such change.  If the Warrant
Stock or other  securities  issuable  upon  exercise  hereof are  subdivided  or
combined into a greater or smaller number of shares of such security, the number
of shares issuable hereunder shall be proportionately increased or decreased, as
the case may be, and the  Exercise  Price  shall be  proportionately  reduced or
increased,  as the case may be, in both cases  according  to the ratio which the
total number of shares of such security to be outstanding immediately after such
event  bears  to the  total  number  of  shares  of  such  security  outstanding
immediately  prior to such event.  The Corporation  shall give the Holder prompt
written notice of any change in the type of securities issuable  hereunder,  any
adjustment of the Exercise Price for the securities issuable hereunder,  and any
increase or decrease in the number of shares issuable hereunder.

12.      Transferability; Compliance with Securities Laws.

         (a) This Warrant may not be transferred or assigned in whole or in part
without  compliance with all applicable federal and state securities laws by the
transferor and transferee  (including the delivery of investment  representation
letters  and legal  opinions  reasonably  satisfactory  to the  Corporation,  if
requested  by the  Corporation).  Subject  to such  restrictions,  prior  to the
Expiration  Time, this Warrant and all rights  hereunder are transferable by the
Holder hereof,  in whole or in part, at the office or agency of the  Corporation
referred to in Section 2 hereof. Any such transfer shall be made in person or by
the Holder's duly authorized  attorney,  upon surrender of this Warrant together
with the Assignment Form attached hereto properly endorsed.

         (b) The Holder of this Warrant, by acceptance hereof, acknowledges that
this  Warrant and the Warrant  Stock  issuable  upon  exercise  hereof are being
acquired  solely for the Holder's own account and not as a nominee for any other
party, and for investment, and that the Holder will not offer, sell or otherwise
dispose  of this  Warrant  or any  shares of  Warrant  Stock to be  issued  upon
exercise hereof except under  circumstances  that will not result in a violation
of the Securities Act of 1933, as amended,  or any state  securities  laws. Upon
exercise of this  Warrant,  the Holder shall,  if requested by the  Corporation,
confirm in writing,  in a form satisfactory to the Corporation,  that the shares
of Warrant Stock so purchased are being acquired solely for Holder's own account
and not as a nominee for any other party,  for  investment,  and not with a view
toward distribution or resale.

         (c) The Warrant Stock has not been and,  except as set forth in Section
4, will not be registered under the Securities Act of 1933, as amended, and this
Warrant  may not be  exercised  except  by (i) the  original  purchaser  of this
Warrant from the Corporation or (ii) an "accredited investor" as defined in Rule
501(a)  under  the  Securities  Act  of  1933,  as  amended.   Each  certificate
representing  the  Warrant  Stock or other  securities  issued in respect of the
Warrant Stock upon any stock split,  stock dividend,  recapitalization,  merger,
consolidation or similar event,  shall be stamped or otherwise  imprinted with a
legend  substantially  in the following form (in addition to any legend required
under applicable securities laws):

SHARES MAY NOT BE SOLD OR  TRANSFERRED  IN THE ABSENCE OF SUCH  REGISTRATION  OR

DELIVERY REQUIREMENTS OF SAID ACT.

issue thereof,  and will be issued in compliance with all applicable federal and
state securities laws; and
