                            SC&T International, Inc.

It is hereby certified that:

        1. The name of the Company  (hereinafter  called the  "Company") is SC&T

        2.  The  certificate  of  incorporation  of the  Company  authorize  the

authority provided therein to issue any or all of said shares in one (1) or more
series and by resolution or resolutions to establish the  designation and number
and to fix the relative rights and preferences of each series to be issued.

        3. The Board of  Directors  of the  Company,  pursuant to the  authority
expressly  vested in it as aforesaid,  has duly adopted as of June 10, 1996, the
following resolutions creating a Series A issue of Preferred Stock:

        RESOLVED,  that One  Thousand  Fifty-one  (1,051)  of the  Five  Million
(5,000,000)  authorized  shares  of  Preferred  Stock  of the  Company  shall be
designated Series A Preferred Stock, $.01 par value per share, and shall possess
the rights and preferences set forth below:

        Section 1. Designation and Amount.  The shares of such series shall have
a par  value of $.01 per share and  shall be  designated  as Series A  Preferred
Stock (the "Series A Preferred Stock") and the number of shares constituting the
Series A Preferred Stock shall be One Thousand Fifty-one  (1,051).  The Series A
Preferred  Stock shall be offered at a purchase  price of Ten  Thousand  Dollars
($10,000) per share (the "Original Series A Issue Price"), with an eight percent
(8%) per annum accretion rate as set forth herein.

        Section 2. Rank. The Series A Preferred  Stock shall rank: (i) junior to
any other  class or series of capital  stock of the  Company  hereafter  created
specifically  ranking  by its  terms  senior  to the  Series A  Preferred  Stock
(collectively,  the  "Senior  Securities");  (ii) prior to all of the  Company's
Common  Stock,  $.01 par value per share  ("Common  Stock");  (iii) prior to any
class  or  series  of  capital  stock  of  the  Company  hereafter  created  not
specifically  ranking  by its terms  senior to or on  parity  with any  Series A
Preferred Stock of whatever  subdivision  (collectively,  with the Common Stock,
"Junior  Securities");  and (iv) on parity  with any class or series of  capital
stock of the  Company  hereafter  created  specifically  ranking by its terms on
parity with the Series A Preferred  Stock ("Parity  Securities") in each case as
to  distributions of assets upon  liquidation,  dissolution or winding up of the
Company, whether voluntary or involuntary (all such distributions being referred
to collectively as "Distributions").

        Section  3.  Dividends.  The  Series  A  Preferred  Stock  will  bear no
dividends, and the holders of the Series A Preferred Stock ("Holders") shall not
be entitled to receive dividends on the Series A Preferred Stock.

        Section 4. Liquidation Preference.

                (a) In the event of any  liquidation,  dissolution or winding up
of the Company, either voluntary or involuntary, the Holders of shares of Series
A  Preferred  Stock  shall  be  entitled  to  receive,   immediately  after  any
distributions  to Senior  Securities  required by the Company's  Certificate  of
Incorporation or any certificate of designation,  and prior in preference to any
distribution to Junior  Securities but in parity with any distribution to Parity
Securities,  an amount per share equal to the sum of (i) the  Original  Series A
Issue Price for each  outstanding  share of Series A Preferred Stock and (ii) an
amount  equal to eight  percent  (8%) of the  Original  Series A Issue Price per
annum for the 

period that has passed since the date that, in connection with the  consummation
of the  purchase  by  Holder of shares  of  Series A  Preferred  Stock  from the
Company,  the escrow agent first had in its possession funds  representing  full
payment for the shares of Series A Preferred  Stock (such amount being  referred
to herein as the  "Premium").  If upon the  occurrence of such event,  and after
payment  in  full  of the  preferential  amounts  with  respect  to  the  Senior
Securities,  the assets and funds available to be distributed  among the Holders
of the Series A Preferred Stock and Parity  Securities  shall be insufficient to
permit the payment to such Holders of the full  preferential  amounts due to the
Holders of the Series A Preferred Stock and the Parity Securities, respectively,
then  the  entire  assets  and  funds  of  the  Company  legally  available  for
distribution  shall be  distributed  among the Holders of the Series A Preferred
Stock and the Parity Securities,  pro rata, based on the respective  liquidation
amounts  to  which  each  such  series  of stock is  entitled  by the  Company's
Certificate of  Incorporation  and any  certificate(s)  of designation  relating
thereto.

                (b)  Upon  the  completion  of  the  distribution   required  by
subsection 4(a), if assets remain in this Company,  they shall be distributed to
holders of Junior  Securities in accordance  with the Company's  Certificate  of
Incorporation including any duly adopted certificate(s) of designation.

                (c) At each Holder's option,  a sale,  conveyance or disposition
of all or substantially  all of the assets of the Company or the effectuation by
the Company of a  transaction  or series of related  transactions  in which more
than fifty percent (50%) of the voting power of the Company is disposed of shall
be deemed to be a  liquidation,  dissolution or winding up within the meaning of
this Section 4;  provided  further  that an event  described in the prior clause
that the Holder does not elect to treat as a  liquidation  and a  consolidation,
merger,  acquisition,  or other business combination of the Company with or into
any  other  company  or  companies  shall  not  be  treated  as  a  liquidation,
dissolution  or  winding up within the  meaning of this  Section 4, but  instead
shall be treated pursuant to Section 5(f) hereof.

                (d) In the event  that,  immediately  prior to the  closing of a
transaction  described  in Section  4(c) which would  constitute  a  liquidation
event,  the cash  distributions  required by Section  4(a) or Section 6 have not
been made,  the Company  shall  either:  (i) cause such  closing to be postponed
until such cash  distributions  have been made, or (ii) cancel such transaction,
in which event the rights of the  Holders of Series A  Preferred  Stock shall be
the same as existing immediately prior to such proposed transaction.

        Section 5.  Conversion.  The record  Holders of this  Series A Preferred
Stock shall have conversion rights as follows (the "Conversion Rights"):

                (a) Right to Convert.  Each record  Holder of Series A Preferred
Stock  shall be entitled  (at the times and in the amounts set forth  below) and
subject to the Company's  right of redemption  set forth in Section 6(a), at the
office of the Company or any  transfer  agent for the Series A  Preferred  Stock
(the "Transfer  Agent"),  to convert (in multiples of one (1) share of Preferred
Stock) as follows: (x) up to one-third (1/3) of the shares of Series A Preferred
Stock  initially  issued to such  Holder at any time  beginning  sixty (60) days
following  the date of the  last  closing  of a  purchase  and sale of  Series A
Preferred  Stock that occurs  pursuant to the offering of the Series A Preferred
Stock by the Company (the "Last Closing Date") and at any time  thereafter,  (y)
up to an additional  one-third  (1/3) of the shares of Series A Preferred  Stock
initially issued to such Holder at any time beginning ninety (90) days following
the Last Closing Date and at any time thereafter, and (z) all remaining Series A
Preferred  Stock held by such Holder at any time  beginning  one hundred  twenty
(120) days following the Last Closing Date (each of the time periods  referenced
in  subclauses  (x),  (y) and (z) is  hereinafter  referred to  singularly  as a
"Conversion  Gate") at the office of the Company or any  Transfer  Agent for the
Series A Preferred  Stock,  into that number of  fully-paid  and  non-assessable
shares  of  Common  Stock  of the  Company  calculated  in  accordance  with the
following formula (the "Conversion Rate"):

         Number of shares  issued upon  conversion  of one (1) share of Series A
Preferred Stock =

                        (.08) (N/365) (10,000) + 10,000
                        -------------------------------
                                Conversion Price

                                       2

        where,

        * N= the number of days between (i) the date that,  in  connection  with
        the consummation of the initial purchase by Holder of shares of Series A
        Preferred  Stock from the  Company,  the escrow  agent  first had in its
        possession  funds  representing  full payment for the shares of Series A
        Preferred  Stock for which  conversion  is being  elected,  and (ii) the
        applicable Date of Conversion (as defined in Section 5(c)(iv) below) for
        the shares of Series A  Preferred  Stock for which  conversion  is being
        elected, and

        *  Conversion  Price = the lesser of (x) $ 7.75 (the  "Fixed  Conversion
        Price"),  or (y) 85% of the average  Closing Bid Price,  as that term is
        defined  below,  of the Company's  Common Stock for the ten (10) trading
        days immediately preceding the Date of Conversion, as defined below (the
        "Variable Conversion Price").

        For purposes hereof, the term "Closing Bid Price" shall mean the closing
bid price on the Nasdaq Small Cap Market,  or if no longer  traded on the Nasdaq
Small Cap Market,  the closing bid price on the  principal  national  securities
exchange or the  National  Market  System on which the Common Stock is so traded
and if not  available,  the  mean of the high and low  prices  on the  principal
national  securities  exchange or the National Market System on which the Common
Stock is so traded.

                (b)  Mechanics  of  Conversion.  In  order to  convert  Series A
Preferred  Stock into full shares of Common Stock,  the Holder shall (i) fax, on
or prior to 11:59 p.m., Phoenix, Arizona time (the "Conversion Notice Deadline")
on the date of  conversion,  a copy of the fully  executed  notice of conversion
("Notice  of  Conversion")  to the  Company at the office of the  Company or its
designated  transfer  agent (the  "Transfer  Agent")  for the Series A Preferred
Stock stating that the Holder elects to convert,  which notice shall specify the
date of  conversion,  the  number of shares  of Series A  Preferred  Stock to be
converted,  the applicable  conversion  price and a calculation of the number of
shares of Common Stock  issuable upon such  conversion  (together with a copy of
the front page of each  certificate  to be  converted)  and (ii)  surrender to a
common  courier for delivery to the office of the Transfer  Agent,  the original
certificates  representing  the Series A Preferred  Stock being  converted  (the
"Preferred Stock Certificates"),  duly endorsed for transfer; provided, however,
that the Company  shall not be obligated to issue  certificates  evidencing  the
shares of Common Stock issuable upon such conversion unless either the Preferred
Stock Certificates are delivered to the Transfer Agent as provided above, or the
Holder  notifies the Company or its Transfer Agent that such  certificates  have
been lost, stolen or destroyed  (subject to the requirements of subparagraph (i)
below).  Upon receipt by Company of a facsimile  copy of a Notice of Conversion,
Company shall immediately send, via facsimile,  a confirmation of receipt of the
Notice of Conversion to Holder which shall specify that the Notice of Conversion
has been received and the name and telephone  number of a contact  person at the
Company whom the Holder  should  contact  regarding  information  related to the
Conversion.  In the case of a dispute as to the  calculation  of the  Conversion
Rate,  the Company shall  promptly issue to the Holder the number of Shares that
are not  disputed  and shall  submit the  disputed  calculations  to its outside
accountant via facsimile  within three (3) days of receipt of Holder's Notice of
Conversion.  The Company shall cause the accountant to perform the  calculations
and notify Company and Holder of the results no later than ninety-six (96) hours
from the time it receives the disputed  calculations.  Accountant's  calculation
shall be deemed conclusive absent manifest error.

                        (i) Lost or Stolen  Certificates.  Upon  receipt  by the
Company  of  evidence  of the loss,  theft,  destruction  or  mutilation  of any
Preferred Stock  Certificates  representing  shares of Series A Preferred Stock,
and (in the case of  loss,  theft  or  destruction)  of  indemnity  or  security
reasonably  satisfactory to the Company,  and upon surrender and cancellation of
the Preferred Stock Certificate(s),  if mutilated, the Company shall execute and
deliver new  Preferred  Stock  Certificate(s)  of like tenor and date.  However,
Company shall not be obligated to re-issue such lost or stolen  Preferred  Stock
Certificates if Holder contemporaneously requests Company to convert such Series
A Preferred Stock into Common Stock.

                        (ii) Delivery of Common Stock Upon  Conversion.  Subject
to  paragraph  5(b)  hereof,  no later than the close of  business on the second
(2nd) business day (the "Deadline") after receipt by the Company or the Transfer
Agent of a facsimile  copy of a Notice of  Conversion  and receipt by Company or
the Transfer  Agent of all necessary  documentation  duly executed and in
                                       3

proper form required for conversion, including the receipt by the Transfer Agent
of the original Preferred Stock Certificates to be converted (or after provision
for security or indemnification  in the case of lost or destroyed  certificates,
if  required),  the  Company  shall or shall  cause  the  Transfer  Agent to (as
applicable)  issue and surrender to a common courier for either overnight or (if
delivery is outside the United States) two (2) day delivery to the Holder at the
address of the Holder as shown on the stock records of the Company a certificate
for the number of shares of Common  Stock to which the Holder  shall be entitled
as aforesaid.

                        (iii) No  Fractional  Shares.  If any  conversion of the
Series A Preferred  Stock would create a  fractional  share of Common Stock or a
right to acquire a fractional share of Common Stock, such fractional share shall
be  disregarded  and  the  number  of  shares  of  Common  Stock  issuable  upon
conversion, in the aggregate, shall be the next lower number of shares.

                        (iv) Date of  Conversion.  The date on which  conversion
occurs  (the "Date of  Conversion")  shall be deemed to be the date set forth in
such Notice of  Conversion,  provided (i) that the advance copy of the Notice of
Conversion is faxed to the Company before 11:59 p.m., Phoenix,  Arizona time, on
the Date of Conversion,  and (ii) that the original Preferred Stock Certificates
representing  the  shares  of  Series  A  Preferred  Stock to be  converted  are
surrendered by depositing such certificates  with a common courier,  as provided
above,  and received by the Transfer  Agent within five (5) business  days after
the Date of Conversion.  The person or persons entitled to receive the shares of
Common Stock issuable upon such conversion  shall be treated for all purposes as
the  record  Holder or  Holders  of such  shares of Common  Stock on the Date of
Conversion. If the original Preferred Stock Certificates representing the Series
A Preferred  Stock to be converted are not received by the Transfer Agent within
five (5) business  days after the Date of  Conversion or if the facsimile of the
Notice of Conversion is not received by the Company or its  designated  Transfer
Agent prior to the Conversion Notice Deadline, the Notice of Conversion,  at the
Company's option, may be declared null and void.

                (c) Reservation of Stock Issuable Upon  Conversion.  The Company
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock,  solely for the purpose of effecting  the  conversion of
the Series A Preferred Stock, such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all then outstanding
Series A  Preferred  Stock;  and if at any time the  number  of  authorized  but
unissued shares of Common Stock shall not be sufficient to effect the conversion
of all then  outstanding  shares of Series A Preferred  Stock,  the Company will
take such  corporate  action as may be necessary to increase its  authorized but
unissued  shares of Common Stock to such number of shares as shall be sufficient
for such purpose.

                (d)  Automatic  Conversion.  Subject to the  Company's  right of
redemption set forth in Section 6 hereof, each share of Series A Preferred Stock
outstanding  on the date which is three (3) years  after the Last  Closing  Date
automatically  shall  be  converted  into  Common  Stock  on  such  date  at the
Conversion  Rate then in effect  (calculated  in accordance  with the formula in
Section  5(a)  above),  and the date  which is three  (3)  years  after the Last
Closing  Date  shall be  deemed  the Date of  Conversion  with  respect  to such
conversion.

                (e)  Adjustment to Conversion Rate.

                        (i)  Adjustment to Fixed  Conversion  Price Due to Stock
Split,  Stock Dividend,  Etc. If, prior to the conversion of all of the Series A
Preferred Stock,  the number of outstanding  shares of Common Stock is increased
by a stock split,  stock dividend,  or other similar event, the Fixed Conversion
Price shall be proportionately  reduced,  or if the number of outstanding shares
of Common Stock is decreased by a combination or  reclassification of shares, or
other  similar  event,  the  Fixed  Conversion  Price  shall be  proportionately
increased.

                        (ii) Adjustment to Variable Conversion Price. If, at any
time when any shares of the Series A Preferred Stock are issued and outstanding,
the number of outstanding  shares of Common Stock is increased or decreased by a
stock split,  stock  dividend,  or other similar  event,  which event shall have
taken place during the  reference  period for  determination  of the  Conversion
Price for any  conversion  of the Series A Preferred  Stock,  then the  Variable
Conversion  Price shall be
                                       4

calculated  giving  appropriate  effect  to the  stock  split,  stock  dividend,
combination,  reclassification  or other  similar event for all five (5) trading
days immediately preceding the Date of Conversion.

                        (iii) Adjustment Due to Merger, Consolidation,  Etc. If,
prior to the  conversion  of all Series A  Preferred  Stock,  there shall be any
merger, consolidation, exchange of shares, recapitalization,  reorganization, or
other similar event,  as a result of which shares of Common Stock of the Company
shall be changed  into the same or a  different  number of shares of the same or
another class or classes of stock or securities of the Company or another entity
or there is a sale of all or substantially  all the Company's assets or there is
a change of control  transaction  not  deemed to be a  liquidation  pursuant  to
section 4(c), then the Holders of Series A Preferred Stock shall thereafter have
the right to receive upon conversion of Series A Preferred Stock, upon the basis
and upon the terms and conditions  specified herein and in lieu of the shares of
Common Stock  immediately  theretofore  issuable  upon  conversion,  such stock,
securities  and/or other  assets  which the Holder  would have been  entitled to
receive in such  transaction  had the Series A  Preferred  Stock been  converted
immediately  prior  to  such  transaction,  and in  any  such  case  appropriate
provisions shall be made with respect to the rights and interests of the Holders
of the  Series  A  Preferred  Stock  to  the  end  that  the  provisions  hereof
(including, without limitation,  provisions for the adjustment of the Conversion
Price and of the  number of shares  issuable  upon  conversion  of the  Series A
Preferred Stock) shall thereafter be applicable, as nearly as may be practicable
in relation to any securities  thereafter  deliverable upon the exercise hereof.
The  Company  shall not  effect any  transaction  described  in this  subsection
5(e)(iii)  unless (a) it first gives thirty (30)  business  days prior notice of
such   merger,    consolidation,    exchange   of   shares,    recapitalization,
reorganization,  or other  similar  event (during which time the Holder shall be
entitled to convert its shares of Series A  Preferred  Stock into Common  Stock)
and (b) the resulting successor or acquiring entity (if not the Company) assumes
by written  instrument the obligations of the Company under this  Certificate of
Designation including this subsection 5(e)(iii).

                        (iv) No Fractional  Shares. If any adjustment under this
Section  5(e)  would  create a  fractional  share of Common  Stock or a right to
acquire a  fractional  share of Common  Stock,  such  fractional  share shall be
disregarded  and the number of shares of Common Stock  issuable upon  conversion
shall be the next lower number of shares.

        Section 6. Redemption by Company.

                (a)  Company's  Right  to  Redeem  Upon  Receipt  of  Notice  of
Conversion.  If the Conversion  Price of the Company's Common Stock is less than
the Fixed  Conversion Price (as defined in Section 5(a)), at the time of receipt
of a Notice of  Conversion  pursuant  to Section 5, the  Company  shall have the
right,  in its sole  discretion,  to  redeem  in  whole or in part any  Series A
Preferred Stock submitted for  conversion,  immediately  prior to and in lieu of
conversion  ("Redemption Upon Receipt of Notice of Conversion").  If the Company
elects to redeem some,  but not all, of the Series A Preferred  Stock  submitted
for conversion, the Company shall redeem from among the Series A Preferred Stock
submitted  by the various  Holders for  conversion  on the  applicable  date,  a
pro-rata amount from each such Holder so submitting Series A Preferred Stock for
conversion.

                        (i)  Redemption  Price  Upon  Receipt  of  a  Notice  of
Conversion.  The  redemption  price per share of Series A Preferred  Stock under
this Section 6(a) shall be calculated in accordance  with the following  formula
("Redemption Rate"):

 [[(.08)(N/365) (10,000)] + 10,000] x Closing Bid Price on Date of Conversion
                                      ---------------------------------------
                                                 Conversion Price

where,

        "N", "Date of Conversion",  "Closing Bid Price" and  "Conversion  Price"
shall have the same meanings as defined in Section 5.

                        (ii)  Mechanics of Redemption  Upon Receipt of Notice of
Conversion.  The Company  shall effect each such  redemption by giving notice of
its election to redeem,  by facsimile,
                                       5

by 5:00 p.m.  New York City time the next  business day  following  receipt of a
Notice of Conversion from a Holder, and the Company shall provide a copy of such
redemption notice by overnight or two (2) day courier,  to (A) the Holder of the
Series A Preferred  Stock  submitted for conversion at the address and facsimile
number of such  Holder  appearing  in the  Company's  register  for the Series A
Preferred  Stock and (B) the Company's  Transfer Agent.  Such redemption  notice
shall  indicate  whether  the  Company  will  redeem all or part of the Series A
Preferred Stock submitted for conversion and the applicable redemption price.

                (b)  Company's  Right to  Redeem at its  Election.  At any time,
commencing  twelve (12) months and one (1) day after the Last Closing Date,  the
Company shall have the right, in its sole discretion,  to redeem ("Redemption at
Company's  Election"),  from time to time,  any or all of the Series A Preferred
Stock;  provided  (i) Company  shall first  provide  thirty (30)  business  days
advance written notice as provided in subparagraph  6(b)(ii) below (which can be
given beginning thirty (30) business days prior to the date which is twelve (12)
months and one (1) day after the Last Closing  Date),  and (ii) that the Company
shall only be entitled to redeem  Series A Preferred  Stock  having an aggregate
Stated Value (as defined  below) of at least One Million  Five Hundred  Thousand
Dollars ($1,500,000).  If the Company elects to redeem some, but not all, of the
Series A Preferred  Stock,  the Company shall redeem a pro-rata amount from each
Holder of the Series A Preferred Stock.

                        (i)  Redemption   Price  At  Company's   Election.   The
"Redemption Price At Company's  Election" shall be calculated as a percentage of
Stated Value,  as that term is defined  below,  of the Series A Preferred  Stock
redeemed pursuant to this Section 6(b), which percentage shall vary depending on
the date of Redemption at Company's  Election (as defined  below),  and shall be
determined as follows:

   Date of Notice of Redemption at Company's Election          % of Stated Value
   --------------------------------------------------          -----------------
   12 months and 1 day to 18 months following Last Closing Date       130%
   18 months and 1 day to 24 months following Last Closing Date       125%
   24 months and 1 day to 30 months following Last Closing Date       120%
   30 months and 1 day to 36 months following Last Closing Date       115%

        For purposes  hereof,  "Stated  Value" shall mean the Original  Series A
Issue  Price (as  defined in Section  4(a)) of the shares of Series A  Preferred
Stock being  redeemed  pursuant to this Section 6(b),  together with the accrued
but unpaid Premium (as defined in Section 4(a)).

                        (ii) Mechanics of Redemption at Company's Election.  The
Company  shall  effect  each such  redemption  by giving  at least  thirty  (30)
business  days  prior  written  notice   ("Notice  of  Redemption  At  Company's
Election")  to (A) the  Holders of the Series A  Preferred  Stock  selected  for
redemption,  at the address and facsimile number of such Holder appearing in the
Company's  Series A Preferred stock register and (B) the Transfer  Agent,  which
Notice  of  Redemption  At  Company's  Election  shall be  deemed  to have  been
delivered  three (3) business days after the Company's  mailing (by overnight or
two (2) day courier,  with a copy by  facsimile) of such Notice of Redemption At
Company's  Election.  Such Notice of  Redemption  At  Company's  Election  shall
indicate  (i) the  number of shares of Series A  Preferred  Stock that have been
selected  for  redemption,  (ii) the date  which  such  redemption  is to become
effective  (the  "Date of  Redemption  At  Company's  Election")  and  (iii) the
applicable  Redemption  Price At Company's  Election,  as defined in  subsection
(b)(i) above.  Notwithstanding  the above,  Holder may convert into Common Stock
pursuant to section 5, prior to the close of business on the Date of  Redemption
at  Company's  Election,  any Series A  Preferred  Stock  which it is  otherwise
entitled to convert,  including  Series A Preferred Stock that has been selected
for redemption at Company's election pursuant to this subsection 6(b); provided,
however,  that the Company  shall  still be  entitled  to exercise  its right to
redeem upon receipt of a Notice of Conversion pursuant to section 6(a).

        (c) Company Must Have Immediately  Available Funds or Credit Facilities.
The Company  shall not be entitled to send any  Redemption  Notice and begin the
redemption procedure under Sections 6(a) and 6(b) unless it has:

                        (i) the full  amount  of the  redemption  price in cash,
available  in a  demand  or other  immediately  available  account  in a bank or
similar financial institution; or
                                       6

                        (ii)  immediately  available credit  facilities,  in the
full  amount  of  the  redemption  price  with  a  bank  or  similar   financial
institution; or

                        (iii) an agreement with a standby underwriter willing to
purchase  from the  Company a  sufficient  number of shares of stock to  provide
proceeds  necessary  to  redeem  any  stock  that  is  not  converted  prior  to
redemption; or

                        (iv) a  combination  of the items set forth in (i), (ii)
and (iii) above, aggregating the full amount of the redemption price.

        (d) Payment of Redemption Price.

                        (i)  Each  Holder   submitting   Preferred  Stock  being
redeemed  under  this  Section  6 shall  send  their  Series A  Preferred  Stock
Certificates so redeemed to the Company or its Transfer  Agent,  and the Company
shall  pay the  applicable  redemption  price  to that  Holder  within  ten (10)
business days of the Date of Redemption at Company's Election. The Company shall
not be obligated to deliver the  redemption  price  unless the  Preferred  Stock
Certificates so redeemed are delivered to the Company or its Transfer Agent, or,
in the event one (1) or more certificates have been lost,  stolen,  mutilated or
destroyed, unless the Holder has complied with Section 5(b)(i).

                        (ii) If  Company  elects to redeem  pursuant  to Section
6(a) hereof,  and Company  fails to pay Holder the  redemption  price within the
time frame as required by this Section 6(d),  then Company shall issue shares of
Common  Stock to any such  Holder who has  submitted a Notice of  Conversion  in
compliance with Section 5(b) hereof.  The shares to be issued to Holder pursuant
to this provision  shall be the number of shares  determined  using a Conversion
Price  that  equals the lesser of (i) the  Conversion  Price on the date  Holder
sends its Notice of  Conversion  to Company or Transfer  Agent via  facsimile or
(ii) the  Conversion  Price on the date the Transfer  Agent issues  Common Stock
pursuant to this Section 6(d)(ii).

                        (iii)  Notwithstanding the foregoing,  in the event that
the  certificates  evidencing  the Series A  Preferred  Stock  redeemed  are not
delivered to the Transfer Agent as provided herein, the redemption of the Series
A Preferred Stock pursuant to this Section 6 shall still be deemed  effective as
of the Date of Redemption.

                (e) Blackout Period.  Notwithstanding the foregoing, the Company
may not either send out a redemption  notice or effect a redemption  pursuant to
Section 6(b) above during a Blackout  Period  (defined as a period  during which
the Company's  officers or directors  would not be entitled to buy or sell stock
because of their holding of material non-public information), unless the Company
shall first  disclose the non-public  information  that resulted in the Blackout
Period;  provided,  however, that no redemption shall be effected until at least
ten (10) days after the Company shall have given the Holder  written notice that
the Blackout Period has been lifted.

       Section 7. Advance Notice of Redemption.

                (a) Holder's Right to Elect to Receive Notice of Cash Redemption
by the  Company.  Holder  shall  have the right to  require  Company  to provide
advance notice stating  whether the Company will elect to redeem Holder's shares
of Series A Preferred Stock in cash, pursuant to the Company's redemption rights
discussed in Section 6(a).

                (b)  Mechanics of Holder's  Election  Notice.  Holder shall send
notice  ("Election  Notice")  to the  Company  and such other  person(s)  as the
Company may designate,  via  facsimile,  stating  Holder's  intention to require
Company to disclose  that if Holder were to  exercise  his,  her or its right of
conversion  (pursuant  to  Section 5) whether  Company  would  elect to redeem a
specific  number of shares of Holder's Series A Preferred Stock for cash in lieu
of issuing  Common Stock.  Company is required to disclose to Holder what action
Company  would  take  over the  subsequent  twenty  (20)  business  day  period,
including the date of such Election Notice,  as further  discussed in subsection
7(c).
                                       7

                (c)  Company's  Response.  Upon  receipt  by  the  Company  of a
facsimile  copy of an Election  Notice,  Company  shall  immediately  send,  via
facsimile,  a confirmation  of receipt of the Election  Notice to Holder,  which
shall  specify  that the  Election  Notice  has been  received  and the name and
telephone  number of a contact  person at the  Company  whom the  Holder  should
contact  regarding   information   related  to  the  requested  advance  notice.
Thereafter,  the  Company  must  respond  by the close of  business  on the next
business day following receipt of Holder's Election Notice (1) via facsimile and
(2) by depositing  such  response with an overnight or two (2) day courier.  The
Company's response must state whether it would redeem the shares, in whole or in
part, or allow  conversion  into shares of Common Stock without  redemption.  If
Company does not respond to Holder within one (1) business day via facsimile and
overnight or two (2) day courier,  Company  shall be required to issue to Holder
Common Stock upon Holder's conversion within the subsequent twenty (20) business
day period of Holder's Election Notice.  However,  if the Company's Common Stock
price  decreases so that under the Conversion  Rate Company would be required to
issue more than an additional  ten percent (10% ) of shares of Common Stock than
Holder was  entitled  to receive at the time Holder  sent  Company its  Election
Notice and if the Conversion  Price is below the Fixed  Conversion  Price,  then
Company shall no longer be bound to convert Holder's Preferred Stock into Common
Stock but may elect to redeem for cash.

        Section 8. Voting  Rights.  The Holders of the Series A Preferred  Stock
shall have no voting  power  whatsoever,  except as  otherwise  provided  by the
Arizona  Business  Corporation  Act ("Arizona  Law"),  and no Holder of Series A
Preferred  Stock shall vote or otherwise  participate in any proceeding in which
actions shall be taken by the Company or the shareholders thereof or be entitled
to notification as to any meeting of the shareholders.

        Notwithstanding   the  above,   Company   shall   provide   Holder  with
notification  of any meeting of the  shareholders  regarding any major corporate
events  affecting  the  Company.  In the event of any taking by the Company of a
record of its shareholders  for the purpose of determining  shareholders who are
entitled to receive payment of any dividend or other distribution,  any right to
subscribe for, purchase or otherwise acquire any share of any class or any other
securities  or  property   (including  by  way  of  merger,   consolidation   or
reorganization),  or  to  receive  any  other  right,  or  for  the  purpose  of
determining  shareholders  who  are  entitled  to vote in  connection  with  any
proposed sale, lease or conveyance of all or substantially  all of the assets of
the  Company,  or any  proposed  liquidation,  dissolution  or winding up of the
Company, the Company shall mail a notice to Holder, at least ten (10) days prior
to the board  meeting  scheduled  for the  purpose  of voting on such  dividend,
distribution,  right or other event, and a brief statement  regarding the amount
and character of such dividend, distribution, right or other event to the extent
known at such time.

        To the extent  that  under  Arizona  Law the vote of the  Holders of the
Series A Preferred Stock, voting separately as a class, is required to authorize
a given action of the Company, the affirmative vote or consent of the Holders of
at least a majority of the shares of the Series A Preferred Stock represented at
a duly held  meeting at which a quorum is  present  or by  written  consent of a
majority of the shares of Series A Preferred  Stock  (except as otherwise may be
required under Arizona Law) shall  constitute the approval of such action by the
class.  To the  extent  that  under  Arizona  Law the  Holders  of the  Series A
Preferred  Stock are entitled to vote on a matter with holders of Common  Stock,
voting  together as one (1) class,  each share of Series A Preferred Stock shall
be entitled  to a number of votes equal to the number of shares of Common  Stock
into which it is then  convertible  using the record date for the taking of such
vote of stockholders as the date as of which the Conversion Price is calculated.
Holders of the Series A Preferred  Stock also shall be entitled to notice of all
shareholder  meetings or written  consents  with  respect to which they would be
entitled  to vote,  which  notice  would be provided  pursuant to the  Company's
by-laws and applicable statutes.

        Section 9. Protective Provision. So long as shares of Series A Preferred
Stock are  outstanding,  the  Company  shall not  without  first  obtaining  the
approval (by vote or written consent, as provided by Arizona Law) of the Holders
of at least sixty-six and two-thirds  percent (66 2/3%) of the then  outstanding
shares  of Series A  Preferred  Stock,  and at least  sixty-six  and  two-thirds
percent (66 2/3%) of the then outstanding Holders:

                (a) alter or change the rights, preferences or privileges of the
Series A Preferred Stock or any Senior  Securities so as to affect adversely the
Series A Preferred Stock; provided,
                                       8

however,  that no such  change  may be  approved  at any time on or prior to the
fortieth  (40th) day  following  the Last  Closing  Date  unless  such change is
unanimously approved by all Holders;

                (b) create any new class or series of stock  having a preference
over  or  on  parity  with  the  Series  A  Preferred   Stock  with  respect  to
Distributions  (as  defined  in  Section  2 above) or  increase  the size of the
authorized number of Series A Preferred; or

                (c) do any act or thing not authorized or  contemplated  by this
Designation  which  would  result in  taxation  of the  holders of shares of the
Series A Preferred Stock under Section 305 of the Internal Revenue Code of 1986,
as  amended  (or  any  comparable  provision  of the  Internal  Revenue  Code as
hereafter from time to time amended).

        In the event Holders of at least  sixty-six and  two-thirds  percent (66
2/3%) of the then  outstanding  shares of Series A Preferred  Stock and at least
sixty-six and two-thirds percent (66 2/3%) of the then outstanding Holders agree
to allow the Company to alter or change the rights, preferences or privileges of
the shares of Series A Preferred Stock,  pursuant to subsection (a) above, so as
to affect the Series A Preferred Stock,  then the Company will deliver notice of
such approved change to the Holders of the Series A Preferred Stock that did not
agree to such  alteration or change (the  "Dissenting  Holders") and  Dissenting
Holders  shall  have the  right for a period of  thirty  (30)  business  days to
convert  pursuant to the terms of this  Certificate of Designation as they exist
prior to such alteration or change  (notwithstanding  the sixty (60) day, ninety
(90) day,  and one hundred  twenty (120) day holding  requirements  set forth in
Section  5(a)  hereof),  or continue to hold their  shares of Series A Preferred
Stock provided,  however, that the Dissenting Holders may not convert anytime on
or before the fortieth (40th) day following the Last Closing Date.

        Section 10.  Status of  Converted  or Redeemed  Stock.  In the event any
shares of Series A Preferred  Stock shall be converted  or redeemed  pursuant to
Section 5 or Section 6 hereof,  the shares so  converted  or  redeemed  shall be
canceled,  shall return to the status of authorized but unissued Preferred Stock
of no  designated  series,  and shall not be issuable by the Company as Series A
Preferred Stock.

        Section  11.  Preference  Rights.  Nothing  contained  herein  shall  be
construed  to prevent the Board of Directors of the Company from issuing one (1)
or more series of Preferred Stock with dividend and/or  liquidation  preferences
junior to the dividend  and  liquidation  preferences  of the Series A Preferred
Stock.

The undersigned, under penalties of perjury, acknowledge that the Certificate is
his or her act and deed or the act and deed of the  Company  and that the  facts
stated in the Certificate are true.
