     Pursuant to a prior vote the Company is currently authorized to issue up to
60,000,000  shares of Common  Stock,  $0.001 par value and  2,000,000  shares of
Preferred Stock, $0.001 par value. As of October 18, 2005,  45,929,944 shares of
Common Stock were issued and  outstanding  and no shares of Preferred Stock were
outstanding. Each share of Common Stock shall be entitled to one (1) vote on all
matters submitted for stockholder approval. The record date for determination of
stockholders  entitled  to notice of and to vote at the  Meeting is October  18,
2005.

     A  majority  of the  outstanding  shares  of Common  Stock of the  Company,
entitled  to vote must be  represented  in person or by proxy at the  Meeting to
constitute a quorum for the transaction of business.

     Under Delaware law, abstentions and broker non-votes are counted as present

Abstentions are treated as a vote against the proposal and broker non-votes will
not be counted  either for or against any proposal to determine if a proposal is
approved.

                                       1


                                    PROPOSAL

          AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO INCREASE THE
                  NUMBER OF AUTHORIZED SHARES OF COMMON STOCK

General Information

     The  Board of  Directors  approved  and  recommends  that the  stockholders
approve an  amendment  to the  Company's  Amended and  Restated  Certificate  of
Incorporation  to increase the number of authorized  shares of common stock from
60,000,000  to  80,000,000  shares.  The  number  of  authorized  shares  of the
Company's  preferred  stock will not be affected by the proposed  increase.  The
amendment will not result in any changes to the issued and outstanding shares of
common  stock of the  Company and will only affect the number of shares that may
be issued by the Company in the future.

Reasons for the Proposal

     The primary purpose of this amendment to our  Certificate of  Incorporation
is to make available for future issuance by us additional shares of common stock
and to have a sufficient  number of  authorized  and  unissued  shares of common
stock to maintain  flexibility  in our  corporate  strategy and  planning.  Such
corporate  purposes  might include  acquiring  other  businesses in exchange for
shares of the Company's  common  stock;  facilitating  broader  ownership of the
Company's  stock  by  effecting  stock  splits  or  issuing  a  stock  dividend;
flexibility  for  possible  future  financings;  and  attracting  and  retaining
valuable  employees  and  directors  through the  issuance of  additional  stock
options or awards.  The Board of Directors believes that these additional shares
will provide the Company with needed  flexibility  to issue shares in the future
without potential expense and delay incident to obtaining  stockholder  approval
for a particular  issuance in the future.  The Company  currently  has no plans,
understandings  or  agreement  for the issuance or use of  additional  shares of
common stock to be authorized under this Proposal.

     As of October  28,  2005,  there  were  45,929,944  shares of common  stock
outstanding,  2,354,680  shares  reserved for previously  granted  options,  and
600,749 shares reserved for previous issued warrants.  Additionally,  a total of
615,578  shares  have been set aside for  future  issuance  under the  Company's
equity  incentive  plans.  Therefore,   the  Company  currently  has  10,499,049
authorized,  unissued and unreserved shares of common stock available for future
issuance.  If this proposal is not adopted, the Company will have relatively few
additional shares of common stock available for employee retention,  financings,
acquisition or other corporate purposes.

     In the past, the Company has utilized  authorized  but unissued  shares for
acquiring additional working capital and for incentives for employees, directors
and consultants.  At the present time there are no specific plans,  arrangements
or understandings in existence or in process for any public or private financing
or  issuance  of  shares  in  an  acquisition.   The  Company's  current  shares
outstanding and shares reserved for issuance as of October 28, 2005,  constitute
in the aggregate 83% of its current authorized shares.  Therefore,  the Board of
Directors  has  determined  that it is desirable for the Company to increase the
number of shares of  authorized  common  stock in order to meet  needs  that may
arise from time to time in the future.

Amendment

     If this  proposal  is adopted by the  stockholders,  Article 4 of the Sixth
Amended and Restated  Certificate  of  Incorporation  will be amended to read as
follows:

          "The  Corporation  is  authorized  to  issue  two  classes  of  stock,
     designated  Common Stock,  $0.001 par value ("Common  Stock") and Preferred
     Stock,  $0.001 par value  ("Preferred  Stock").  The total number of shares
     which  the  Corporation  is  authorized  to issue  is  Eighty  Two  Million
     (82,000,000).  The total number of shares of Common Stock is Eighty Million
     (80,000,000)  and the total  number of  shares  of  Preferred  Stock is Two
     Million (2,000,000).

          Shares of  Preferred  Stock may be issued  from time to time in one or
     more series. The Board of Directors shall determine the designation of each
     series and the  authorized  number of shares of each  series.  The Board of
     Directors is  authorized  to determine  and alter the rights,  preferences,
     privileges and restrictions  granted to or imposed upon any wholly unissued
     series of shares of  Preferred  Stock and to increase or decrease  (but not
     below the number of shares of such series then  outstanding)  the number of

                                       2


     shares of any such series subsequent to the issue of shares of that series.
     If the  number of  shares of any  series  of  Preferred  Stock  shall be so
     decreased,  the shares  constituting  such decrease shall resume the status
     which they had prior to the adoption of the  resolution  originally  fixing
     the number of shares of such series."

          A copy of the Sixth Amended and Restated  Certificate of Incorporation
     is attached as Exhibit A.

Delaware Franchise Tax

     If the Proposal is adopted,  the Company's authorized capital will increase
and the Company  will be subject to an increase in the Delaware  Franchise  Tax.
However,  the Company  believes the increase in the number of authorized  shares
will not materially increase the Delaware Franchise Tax of the Company.

Potential Anti-Takeover Aspects

     Shares of  authorized  and unissued  common stock could be issued in one or
more transactions that could make it more difficult,  and therefore less likely,
for a takeover of the Company. Although the Board of Directors does not have the
present  intention to use the additional  authorized  shares as an anti-takeover
device,  the  issuance  of  additional  common  stock  could  have the effect of
diluting the stock  ownership of persons  seeking control of the Company and the
possibility of such dilution could have a deterrent effect on persons seeking to
acquire  control.  For example,  shares of common stock can be privately  placed
with  purchasers  who support a board of directors in opposing a tender offer or
other hostile  takeover bid, or can be issued to dilute the stock  ownership and
voting power of a third party seeking a merger or other extraordinary  corporate
transaction.  Accordingly,  the power to issue additional shares of common stock
could  enable  the  Board of  Directors  to make it more  difficult  to  replace
incumbent  directors  and to  accomplish  business  combinations  opposed by the
incumbent Board of Directors.

Principal Effects on Outstanding Common Stock

     The  proposal  to increase  the  authorized  capital  stock will affect the
rights of existing  holders of common stock to the extent that future  issuances
of common stock will reduce each existing stockholder's  proportionate ownership
and may dilute  earnings per share of the shares  outstanding at the time of any
such issuance.  If approved,  the amendment to the certificate of  incorporation
will be effective upon filing with the Secretary of State for Delaware.

RECOMMENDATION OF THE BOARD

     THE  BOARD OF  DIRECTORS  RECOMMENDS  A VOTE  "FOR"  THE  AMENDMENT  TO THE
CERTIFICATE  OF  INCORPORATION  TO INCREASE THE NUMBER OF  AUTHORIZED  SHARES OF
COMMON STOCK UNDER THIS PROPOSAL ON THE PROXY CARD.

                                 OTHER BUSINESS

     We do not know of any  business to be  presented  for action at the meeting
other than those  items  listed in the notice of the  meeting  and  referred  to
herein. If any other matters properly come before the meeting or any adjournment
thereof,  it is intended  that the proxies  will be voted in respect  thereof in
accordance with their best judgment pursuant to discretionary  authority granted
in the proxy.

     ALL STOCKHOLDERS ARE URGED TO EXECUTE THE ACCOMPANYING  PROXY AND TO RETURN
IT PROMPTLY IN THE ACCOMPANYING  ENVELOPE.  STOCKHOLDERS MAY REVOKE ANY PROXY IF
SO DESIRED AT ANY TIME BEFORE IT IS VOTED.
