                             QUESTIONS AND ANSWERS

WHY DID I RECEIVE THIS PROXY STATEMENT?


     On  or about November 25, 2002, we  will begin mailing this proxy statement
and accompanying proxy card to everyone who was a shareholder of our company  at
the  close of business on November 18, 2002. We prepared this proxy statement to
let our shareholders know  when and where we  will hold a special  shareholders'
meeting. This proxy statement:


     - includes  information about the matters that  will be discussed and voted
       on at the meeting, and

     - provides you with updated information about our company.

I MAY HAVE RECEIVED MORE THAN ONE PROXY STATEMENT. WHY?

     If you received  more than one  proxy statement, your  shares are  probably
registered  differently or are in more than  one account. Please vote each proxy
card that you received.

WHAT WILL OCCUR AT THE SPECIAL MEETING?

     First, we will  determine whether  enough shareholders are  present at  the
meeting to conduct business. A shareholder will be deemed to be "present" at the
meeting if the shareholder:

     - is present in person; or

     - is  not  present in  person  but has  voted by  proxy  card prior  to the
       meeting.


     All shareholders of record  at the close of  business on November 18,  2002
will  be entitled to vote on matters presented at the meeting or any adjournment
thereof. On the record  date, there were 18,592,565  shares of our common  stock
outstanding.  The holders  of a  majority, or  9,296,283, of  the shares  of our
common stock entitled to vote at the meeting must be represented at the  meeting
in  person or by proxy to  have a quorum for the  transaction of business at the
meeting and to act on the matters specified in this proxy statement. If  holders
of  fewer than 9,296,283 shares  are present at the  meeting, we will adjourn or
reschedule the meeting. Under our Articles  of Incorporation, for each share  of
common  stock that you owned at the close  of business on November 18, 2002, you
are entitled  to one  vote on  all matters  brought before  the meeting  or  any
adjournment thereof.


     A  representative  of  Ernst  & Young  LLP,  our  independent  auditors, is
expected to  be  present  at  the  special  meeting  and  will  be  afforded  an
opportunity  to  make a  statement, if  such representative  so desires,  and to
respond to appropriate questions.

     After each proposal has been voted on  at the meeting, we will discuss  and
take action on any other matter that is properly brought before the meeting. Our
transfer  agent, Computershare Investor Services, LLC,  will count the votes and
act as inspector of election.

     If enough shareholders are present at the meeting to conduct business, then
we will vote  on the proposal  outlined in  this proxy statement  and any  other
business  that  is  properly brought  before  the meeting  and  any adjournments
thereof.

     We know of no other matters that will be presented for consideration at the
special meeting.  If, however,  other  matters or  proposals are  presented  and
properly  come before the meeting, the proxy  holders intend to vote all proxies
in accordance with their  best judgment in the  interest of Zix Corporation  and
our shareholders.

HOW DO I VOTE IF I AM NOT PLANNING TO ATTEND THE SPECIAL MEETING?

     In  addition  to  voting  in  person at  the  meeting,  you  may  mark your
selections on the enclosed  proxy card, date  and sign the  card and return  the
card in the enclosed postage-paid envelope.

     Please  understand that voting by any means  other than voting in person at
the meeting has the effect of  appointing John A. Ryan, our Chairman,  President
and Chief Executive Officer, and Steve M. York, our

                                        1


Senior  Vice President, Chief Financial Officer  and Treasurer, as your proxies.
They will be required to vote on the proposals described in this proxy statement
exactly as you have voted. However, if any other matter requiring a  shareholder
vote  is properly  raised at  the meeting,  then Messrs.  Ryan and  York will be
authorized to use their discretion to vote on such issues on your behalf.

     We encourage you to vote now even if you plan to attend the special meeting
in person. If your shares are in a brokerage account, you may receive  different
voting instructions from your broker.

     Where a shareholder has appropriately specified how a proxy is to be voted,
it  will be  voted accordingly, and  where no  specific direction is  given on a
properly executed proxy card, it will be voted FOR adoption of the proposals set
forth in this proxy statement.

WHAT IF I WANT TO CHANGE MY VOTE?

     You may revoke  your vote  on a  proposal at  any time  before the  special
meeting  for any reason. To  revoke your proxy before  the meeting, write to our
Secretary, Ronald A. Woessner, at 2711 North Haskell Avenue, Suite 2300, LB  36,
Dallas,  Texas 75204-2960. You may also come to the meeting and change your vote
in writing.

HOW DO I RAISE AN ISSUE FOR DISCUSSION OR VOTE AT THE NEXT ANNUAL MEETING?

     If you would like to submit a proposal to be included in next year's  proxy
statement,  you must submit  your proposal in  writing so that  we receive it no
later than February 10, 2003. We will  include your proposal in our next  annual
proxy  statement if it is a proposal that we would be required to include in our
proxy statement pursuant to the rules of the Securities and Exchange  Commission
(we  refer to it as the "SEC"). Under  Rule 14a-8 of the Securities Exchange Act
of  1934,  as  amended,  proposals  of  shareholders  must  conform  to  certain
requirements  as  to form  and may  be  omitted from  the proxy  materials under
certain circumstances. To avoid unnecessary expenditures of time and money,  you
are  urged to review  this rule and,  if questions arise,  consult legal counsel
prior to  submitting a  proposal to  us.  Proposals should  be directed  to  our
Secretary,  Ronald A. Woessner, at our principal executive offices at 2711 North
Haskell Avenue, Suite 2300, LB 36, Dallas, Texas 75204-2960.

WHAT IF MY SHARES ARE IN A BROKERAGE ACCOUNT AND I DO NOT VOTE?

     If your  shares are  in  a brokerage  account and  you  do not  vote,  your
brokerage firm could:

     - vote your shares, if it is permitted by the rules of the NASD; or

     - leave your shares unvoted.

     Under  applicable rules, brokers who hold shares in street name do not have
the authority to vote  on Proposal One without  receiving instructions from  the
beneficial  owner of the shares. If such brokers deliver a proxy with respect to
this special meeting  of the shareholders  and, because of  the rules  described
above do not vote on Proposal One, referred to as "broker non-votes," the shares
represented  by the  proxy will  count for purposes  of determining  if a quorum
exists, but will not be included in vote  totals and will have no effect on  the
outcome with respect to Proposal One.

HOW ARE ABSTENTIONS TREATED?

     Any  shareholder that  is present  at the meeting,  either in  person or by
proxy, but  who abstains  from voting,  will still  be counted  for purposes  of
determining whether a quorum exists. An abstention would have the same effect as
a  vote against the proposal. If you sign your proxy card but do not specify how
you want  to vote  on  a proposal,  then  your shares  will  be voted  FOR  that
proposal.

WHAT VOTE IS NECESSARY TO APPROVE THE PROPOSAL?


     To approve the stock issuance (Proposal One), it is necessary to obtain the
affirmative  vote of a majority of our common stock shares represented in person
or   by   proxy   at    the   meeting.   The   holders    of   the   Series    A


                                        2


Convertible  Preferred Stock have  the right to  one vote for  each share of our
common stock into  which their  Series A  Convertible Preferred  Stock could  be
converted  on the record date. However, the  holders of the Series A Convertible
Preferred Stock have  agreed with us  that they  will not vote  their shares  of
Series A Convertible Preferred Stock with respect to Proposal One.

HOW MUCH WILL THIS SOLICITATION COST, AND WHO WILL PAY FOR IT?


     We  will bear the  cost of solicitation  of proxies, including  the cost of
preparing, printing and  mailing proxy  materials, and the  cost of  reimbursing
brokers for forwarding proxies and proxy statements to their principals. We have
engaged  Georgeson Shareholder to assist in  the solicitation of proxy materials
from shareholders  at  a fee  of  approximately $25,000  plus  reimbursement  of
reasonable  out-of-pocket expenses. Proxies may  also be solicited without extra
compensation  by  our  officers  and   employees  by  telephone  or   otherwise.
Arrangements  may  also  be made  with  brokerage houses  and  other custodians,
nominees and fiduciaries for  the forwarding of  proxy solicitation material  to
beneficial  owners of shares of our common  stock, and we may reimburse them for
reasonable out-of-pocket expenses incurred by them.


WHERE CAN I FIND THE VOTING RESULTS OF THE SPECIAL MEETING?

     We will announce  the voting results  at the meeting  and will publish  the
results  in  a  current  report  on  Form  8-K  promptly  following  the special
shareholders' meeting. You can receive a copy by contacting either our  Investor
Relations   office  at  (214)   515-7357  or  the  SEC   at  (800)  SEC-0330  or

                                 PROPOSAL ONE:

               TO APPROVE THE ISSUANCE OF SHARES OF COMMON STOCK

SEPTEMBER 2002 FINANCING TRANSACTIONS

     On September  18,  2002,  we  announced the  simultaneous  closing  of  two
financing  transactions pursuant to which we  received $16,000,000 in gross cash
proceeds.

     In the first transaction, we issued the following:

     - 819,886 shares of Series A  Convertible Preferred Stock, par value  $1.00
       per share;

     - 1,304,815 shares of Series B Convertible Preferred Stock, par value $1.00
       per share; and

     - warrants to purchase 709,528 shares of our common stock.

     Purchasers  of  the Series  A  Convertible Preferred  Stock  and associated
warrants include  John A.  Ryan,  our chairman,  president and  chief  executive
officer;  Antonio R. Sanchez,  Jr., a director  of our company;  SANTIG. Ltd., a
family limited  partnership for  which Mr.  Sanchez serves  as managing  general
partner;  the 1988 Spendthrift Trust,  a family trust of  which Mr. Sanchez is a
beneficiary; and David P. Cook, the  founder and a former executive officer  and
director  of  our  company.  Mr.  Ryan  purchased  189,205  shares  of  Series A
Convertible Preferred Stock and associated warrants to purchase an aggregate  of
66,518  shares  of our  common stock.  Mr. Sanchez  purchased 126,136  shares of
Series A  Convertible Preferred  Stock and  associated warrants  to purchase  an
aggregate  of 44,345 shares of our  common stock. SANTIG, Ltd. purchased 252,273
shares of  Series  A Convertible  Preferred  Stock and  associated  warrants  to
purchase an aggregate of 88,691 shares of our common stock. The 1988 Spendthrift
Trust  purchased  126,136 shares  of Series  A  Convertible Preferred  Stock and
associated warrants to  purchase an  aggregate of  44,345 shares  of our  common
stock. Mr. Cook purchased 126,136 shares of Series A Convertible Preferred Stock
and  associated warrants to purchase an aggregate of 44,345 shares of our common
stock. Purchasers of  the Series  B Convertible Preferred  Stock and  associated
warrants  include  George  W. Haywood,  a  25.4% beneficial  shareholder  of our
company, and an IRA for the benefit of Mr. Haywood. Mr. Haywood and the IRA  for
the  benefit of Mr. Haywood purchased an aggregate of 947,708 shares of Series B
Convertible Preferred Stock and associated warrants to purchase an aggregate  of
305,986  shares of  common stock.  The aggregate  cash proceeds  from this first
transaction were $8,000,000.

     In the second transaction, we issued:

     - 6.5% Secured Convertible Notes, in a principal amount of $8,000,000 and

     - warrants to purchase 386,473 shares of our common stock

to institutional investors not affiliated  with our company. The aggregate  cash
proceeds  from  this  second  transaction  were  $8,000,000.  The  6.5%  Secured
Convertible Notes  are  generally referred  to  as  the "notes"  in  this  proxy
statement.

     Subject to the limitations described below,

     - the  Series  A  Convertible  Preferred  Stock  and  Series  B Convertible
       Preferred Stock are initially convertible into an aggregate of  2,022,767
       shares of common stock and

     - the  notes  and  the warrants  associated  with the  notes  are initially
       convertible or  exercisable  into an  aggregate  of 2,502,875  shares  of
       common stock.

                                        4


NEED FOR SHAREHOLDER APPROVAL


     Because  our common stock is  listed on the Nasdaq  National Market, we are
subject to Marketplace Rule  4350. Marketplace Rule 4350  requires us to  obtain
the  approval of  our shareholders  before issuing our  common stock  at a price
below the greater of our book price or the market price of our common stock



     - to our officers or directors, or



     - where the  number of  shares of  common  stock issuable  is equal  to  or
       greater than 20% of our outstanding common stock



     With  regard  to the  September 2002  financing transactions,  the relevant
threshold was the market price of our common stock, which, for purposes of these
Nasdaq rules, was determined as of September  16, 2002 and was $3.92 per  share.
The  common  stock  issuable  upon  conversion or  redemption  of  the  Series A
Convertible Preferred Stock  will be  issuable to  John A.  Ryan, our  chairman,
president  and chief executive  officer; Antonio R. Sanchez,  Jr., a director of
our company; SANTIG, Ltd.;  the 1988 Spendthrift Trust;  and David P. Cook,  our
founder  and a former executive  officer and former director  of our company. In
addition, the conversion or  redemption provisions of  the Series A  Convertible
Preferred  Stock may cause the  underlying common stock to  be issued at a price
that is below the market price of our  common stock. The issuance of all of  the
shares  of common  stock which  are potentially  issuable under  the conversion,
redemption and/or  exercise provisions  of the  Series A  Convertible  Preferred
Stock,  the Series  B Convertible  Preferred Stock,  the notes  and the warrants
associated with the  notes, aggregating 4,525,642  shares (exclusive of  accrued
interest  and  dividends), would  exceed the  20% threshold  (3,623,856 shares).
These conversion, redemption and exercise provisions described above include:


     - the Series A Convertible Preferred Stock and the warrants associated with
       the notes each  contain antidilution  protections which  may cause  their
       conversion prices to drop below the market price;

     - the  Series B  Convertible Preferred Stock  and the  notes, which already
       have conversion  prices  below  the market  price,  contain  antidilution
       protections  which  could  cause  their conversion  prices  to  drop even
       further;

     - the final mandatory  redemption provisions  of the  Series A  Convertible
       Preferred  Stock require us to issue our common stock at a price equal to
       the lesser of $3.92 per share or the market price of our common stock  on
       the  date of the  final redemption of the  Series A Convertible Preferred
       Stock; and

     - the mandatory redemption provisions of the Series B Convertible Preferred
       Stock require us to issue our common stock at a price equal to the lesser
       of $3.78 per share or 90% of the market price of our common stock on  the
       date of any redemption.


     For these reasons, pending shareholder approval, the holders of the


     - Series  A  Convertible Preferred  Stock have  agreed that  the conversion
       price of the Series  A Convertible Preferred Stock  shall not drop  below
       $3.92 per share,

     - Series  A Convertible Preferred Stock  and Series B Convertible Preferred
       Stock have agreed  that the aggregate  number of shares  of common  stock
       issuable  upon the conversion  or redemption of  the Series A Convertible
       Preferred Stock and Series B Convertible Preferred Stock shall not exceed
       870,693 shares and

     - notes and the  warrants associated with  the notes have  agreed that  the
       aggregate  number of shares  of common stock  issuable upon conversion of
       the notes and exercise  of the warrants associated  with the notes  shall
       not exceed 2,753,163 shares.


     The  total number  of shares of  common stock currently  issued or issuable
upon conversion,  redemption  and/or exercise  of  all of  these  securities  is
3,623,856, or 19.99% of our outstanding common stock on the date we issued these
securities.  The limitations described  in this paragraph  include any shares of
common stock that may be issuable in respect of antidilution adjustments to  the
conversion or exercise prices of these


                                        5


securities  or an increase in  the number of shares  issuable upon redemption by
reason of a drop in the market price of our common stock.

     In connection with  our issuance  of these  securities, we  agreed to  seek
shareholder approval to issue our common stock at a price below the market price
($3.92 per share)

     - to  the purchasers of  our Series A  Convertible Preferred stock: Messrs.
       Ryan, Sanchez, and Cook and SANTIG, Ltd. and the 1988 Spendthrift Trust.

     - in an amount equal to or greater than 20% of our outstanding common stock
       upon  the  conversion,  redemption  and/or  exercise  of  the  Series   A
       Convertible  Preferred Stock,  the Series B  Convertible Preferred Stock,
       the notes and the warrants associated with the notes.

     The primary  reason we  believe approval  of Proposal  One is  in the  best
interest  of our company is  that, after shareholder approval,  we will have the
ability to  issue our  common  stock in  lieu of  cash  upon the  conversion  or
redemption  of the  Series A Convertible  Preferred Stock,  Series B Convertible
Preferred Stock and the notes and  upon the exercise of the warrants  associated
with  the notes. This  will allow us to  conserve cash for  the operation of our
business.

     Conversely, if  we  have not  obtained  the shareholder  approval  of  this
Proposal  One and are prohibited  from issuing a sufficient  number of shares of
common stock necessary to effect:

     - any attempted optional conversion of the  notes by a holder, each  holder
       of  a note will have the right to force  us to redeem all or a portion of
       the principal amount outstanding thereunder that cannot be converted  for
       a cash payment equal to 100% of the principal amount being redeemed, plus
       all accrued interest thereon;

     - any  attempted  optional exercise  of  the warrants  associated  with the
       notes, a warrant holder will have the right to require us to make a  cash
       payment with respect to the portion of the warrant sought to be exercised
       equal  to  the  difference between  the  warrant exercise  price  and the
       volume-weighted average price of the common stock on the Nasdaq  National
       Market as of the time of the attempted exercise;

     - any  interim mandatory redemption  of the Series  A Convertible Preferred
       Stock, the shares of Series A Convertible Preferred Stock that cannot  be
       redeemed  by the issuance of common stock  must be redeemed by us in cash
       (provided that the notes have been paid in full) or through the  issuance
       of a subordinated note, at our option. Each subordinated note will have a
       one-year  term,  be unsecured,  bear interest  at 6.5%  per annum  and be
       subordinated to the notes;

     - the final  mandatory redemption  of the  Series A  Convertible  Preferred
       Stock,  the shares of Series A Convertible Preferred Stock that cannot be
       redeemed by the issuance of common stock must be redeemed by us in  cash;
       and

     - any mandatory redemption of the Series B Convertible Preferred Stock, the
       shares of Series B Convertible Preferred Stock that cannot be redeemed by
       the  issuance of common  stock must be  redeemed by us  in cash (provided
       that the notes  have been  paid in  full) or  through the  issuance of  a
       subordinated  note, at  our option.  Each subordinated  note will  have a
       one-year term,  be unsecured,  bear interest  at 6.5%  per annum  and  be
       subordinated to the notes.

     If  any one or more of the items described above were to occur, our ability
to fund our  operations would be  severely restricted  and we may  be forced  to
significantly reduce our operations and expenses.

     Please  note that  if we obtain  shareholder approval of  Proposal One, the
number of shares of common stock we may issue upon conversion, redemption and/or
exercise of  these securities  would  not be  limited by  the  20% cap.  If  the
antidilution  provisions of these securities take  effect or if the market price
of our common stock drops,  the number of shares  of common stock issuable  upon
conversion,  redemption  and/or  exercise  of  these  securities  could increase
significantly, thus resulting  in significant  dilution to  our existing  common
stock  shareholders. For a description of the potential dilutive effect of these
securities, see "Potential Dilution and

                                        6

  OUR BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE APPROVAL OF THIS PROPOSAL
                                      ONE.

            BACKGROUND AND REASONS FOR THE ISSUANCE OF THE SERIES A
       CONVERTIBLE PREFERRED STOCK, SERIES B CONVERTIBLE PREFERRED STOCK,
              THE NOTES AND THE WARRANTS ASSOCIATED WITH THE NOTES

     At  June 30, 2002, our principal source  of liquidity was a working capital
position of $6,713,000, including cash and marketable securities of $10,799,000,
and we had  no significant revenues.  In June  of 2002, we  forecasted that  our
existing  cash  and marketable  securities  combined with  scheduled installment
payments due  from resellers  and distributors  were sufficient  to sustain  our
estimated  level of operating expenditures through  the end of the first quarter
of 2003 We had already taken steps in  late 2001 and early 2002 to decrease  our
cash  expenditure rate,  including reductions in  our personnel.  Also, in April
2002 we engaged SoundView Technology Group as our investment banker to assist us
in seeking  additional  funding.  SoundView  contacted  a  number  of  potential
investors  on our behalf and, subsequently,  a New York based investment manager
that manages several institutional investors, agreed to invest $8,000,000 in our
company, contingent upon us obtaining a minimum $6,000,000 investment from other
investors. We were successful in  obtaining an $8,000,000 investment from  other
investors,  and on September 18, 2002,  we announced the simultaneous closing of
the sale of the notes and the associated warrants to the institutional investors
and the  sale of  the Series  A Convertible  Preferred Stock  and the  Series  B
Convertible  Preferred Stock and the associated warrants to the other investors,
pursuant to  which  we  received  an aggregate  of  $16,000,000  in  gross  cash
proceeds.

     As  noted above, some  of our management  and existing investors (including
Antonio  R.  Sanchez,  Jr.,  a  director  and  a  current  beneficial  owner  of
approximately 12.3% of our outstanding common stock; John A. Ryan, our chairman,
president  and chief executive officer; David P.  Cook, our founder and a former
executive officer and  director of our  company; and George  W. Haywood, then  a
23.9%  beneficial shareholder of  our company) purchased shares  of our Series A
Convertible Preferred Stock, Series B Convertible Preferred Stock and associated
warrants pursuant  to the  financing transactions.  Their interests  were  fully
disclosed  to  and  known by  the  board  of directors  in  connection  with its
deliberations regarding the issuance of the Series A Convertible Preferred Stock
and the Series  B Convertible  Preferred Stock  and the  associated warrants.  A
special  committee of disinterested  directors, consisting of  Michael E. Keane,
James S. Marston and Dr. Ben G.  Streetman, reviewed the terms and approved  the
issuance  of  the notes,  the  Series A  Convertible  Preferred Stock,  Series B
Convertible Preferred Stock and the associated warrants and recommended that the
full board of directors approve the issuances of these securities. Mr. Ryan  was
present  at and participated in all the  meetings of the full board of directors
where the terms of the notes, the Series A Convertible Preferred Stock, Series B
Convertible Preferred  Stock  and  associated warrants  were  reviewed,  and  he
participated in the meeting of the full board of directors where the issuance of
these  securities was ultimately approved by the board. Mr. Cook was no longer a
member of  our board  of directors  when the  issuance of  these securities  was
ultimately  approved by  the board. The  terms and issuance  of these securities
were unanimously approved by our board of directors, other than Mr. Sanchez, who
was absent from  the meetings  and did  not participate  in any  of the  board's
deliberations.

     Subject to the limitations described under the heading "Security Agreement"
on  page 18,  we plan  to use the  $16,000,000 in  gross cash  proceeds from the
issuance of  the securities  for  working capital  and other  general  corporate
purposes.

            INTERESTS OF CERTAIN PERSONS IN MATTERS TO BE ACTED UPON

     The  approval of Proposal One  will result in an  increase in the number of
shares of common stock beneficially held by Antonio R. Sanchez, Jr., a  director
and  a current beneficial owner of approximately 12.3% of our outstanding common
stock; John A. Ryan,  our chairman of the  board, president and chief  executive

                                        7


officer; David P. Cook, our founder and a former executive officer and director;
and George W.  Haywood, a  25.4% beneficial holder  of our  common stock.  After
giving  effect to the transactions described  under Proposal One and assuming no
adjustments to the conversion price of the Series A Convertible Preferred  Stock
or  Series B Convertible  Preferred Stock, Mr.  Sanchez may be  deemed to be the
beneficial owner of 2,475,616  shares of our common  stock, and Mr. Sanchez  may
acquire beneficial ownership of up to an additional 133,036 shares of our common
stock  upon the exercise of the warrants held  by him and SANTIG, Ltd.; Mr. Ryan
will beneficially own 902,692  shares of our common  stock and may  beneficially
acquire up to an additional 66,518 more common stock shares upon the exercise of
the  warrants he holds; Mr.  Cook will beneficially own  1,467,590 shares of our
common stock and may beneficially acquire up to an additional 44,345 more common
stock shares  upon the  exercise of  warrants  he holds;  and Mr.  Haywood  will
beneficially  own  5,237,552 shares  of our  common  stock and  may beneficially
acquire up to an additional 305,986  more common stock shares upon the  exercise
of the warrants he holds. The warrants described above are not exercisable until
March 18, 2003.

     outstanding  but  could be  acquired upon  exercise of  an option  or other

                   POTENTIAL DILUTION AND MARKET CONSEQUENCES


     If  Proposal One is approved, the company  will have the flexibility to pay
the redemption  amounts  payable  with  respect  to  the  Series  A  Convertible
Preferred  Stock and the Series  B Convertible Preferred Stock  in shares of our
common stock. This is in contrast to paying the redemption amounts in cash or by
the issuance of a subordinated note, as applicable -- which we would be required
to do in some circumstances if Proposal One is not approved. See "Proposal  One:
To  Approve  The  Issuance  of  Shares of  Common  Stock,  Need  for Shareholder
Approval," above on page 5. To the extent the company uses shares of our  common
stock,  rather than  cash or  a subordinated  note, to  fulfill these redemption
obligations, our existing shareholders could experience significant dilution.


     One-ninth of the shares of Series A Convertible Preferred Stock and  Series
B  Convertible  Preferred  Stock  are  to  be  redeemed  at  two-month intervals
beginning eight months  after issuance. The  value of the  common stock used  to
determine  the number of shares of common  stock to be issued upon redemption of
shares of Series  A Convertible  Preferred Stock  at the  final redemption  date
(that  is, two years after  issuance) will be the lesser  of $3.92 per share and
the market value  of the  common stock  at the time  of redemption,  based on  a
closing  bid average formula. If the market  price of the common stock declines,
the number  of shares  of  common stock  issuable to  the  holders of  Series  A
Convertible  Preferred Stock upon  such final redemption  will increase, perhaps
substantially. There is no "floor" on the market value calculation and therefore
there is  no "ceiling"  on the  number of  shares of  common stock  that may  be
issuable by us upon the final Series A Convertible Preferred Stock redemption. A
substantial  decline in  the market  price of the  common stock  would result in
significant dilution to  the existing holders  of common stock  if the Series  A
Convertible  Preferred Stock shares are redeemed at a substantially lower price.
This effect  will be  magnified if  one or  more interim  redemption amounts  is
deferred to the final redemption date.

     The  value of the  common stock used  to determine the  number of shares of
common stock to  be issued  upon redemption of  shares of  Series B  Convertible
Preferred Stock will be the lesser of $3.78 per share, referred to as the Series
B  Conversion Price, and 90% of the market value of the common stock at the time
of redemption, based on a volume-weighted  average formula. If the market  price
of  the common stock declines, the number  of shares of common stock issuable to
the holders  of  Series  B  Convertible  Preferred  Stock  upon  such  automatic
redemptions  will increase,  perhaps substantially. There  is no  "floor" on the
market value calculation, and therefore there  is no "ceiling" on the number  of
shares  of common stock that  may be issuable by us  upon a Series B Convertible
Preferred Stock redemption.  A substantial decline  in the market  price of  the
common  stock would  result in significant  dilution to the  existing holders of
common stock if the Series B Convertible Preferred Stock shares are redeemed  at
a substantially lower price.

     The  Series  A  Convertible  Preferred  Stock,  the  Series  B  Convertible
Preferred Stock and the notes and the  warrants issued to the purchasers of  the
notes  are convertible or exercisable by the holders into shares of common stock
at any time. The  Series A Conversion  Price is initially  $4.12 per share;  the
Series  B Conversion Price is initially $3.78 per share; and the Note Conversion
Price is  initially $3.78  per share;  and the  exercise price  of the  warrants
associated  with  the notes  is  initially $4.14  per  share. The  conversion or
exercise prices  could  be  lowered,  perhaps substantially,  in  a  variety  of
circumstances.  In the event we  issue, or are deemed  to have issued, shares of
common stock at a price per share  that is less than the conversion or  exercise
prices  then  in effect  (other than  certain  specified exempt  issuances), the
conversion and exercise prices and the number of shares issuable upon conversion
of the  Series  A Convertible  Preferred  Stock  and the  Series  B  Convertible
Preferred  Stock are subject  to weighted average  anti-dilution adjustment, and
the conversion prices and number of shares issuable upon conversion of the notes
and the  associated  warrants  are subject  to  full  anti-dilution  adjustment.
Following  the approval  of our common  shareholders, there would  be no "floor"
that would limit reductions in the conversion price or exercise prices of  these
securities.  Correspondingly, there is  no "ceiling" on the  number of shares of
common stock that may be  issuable, under certain circumstances, following  such
anti-dilution adjustments.

     The  number of  shares of common  stock that may  be issued by  us upon the
conversion or redemption of the shares  of Series A Convertible Preferred  Stock
and  Series B Convertible Preferred  Stock, the conversion of  the notes and the
exercise of the warrants issued  to the purchasers of  the notes may not  exceed
3,623,856

                                        11


prior to the  approval of  our shareholders to  this Proposal  One. Assuming  we
receive  the approval of our shareholders to this Proposal One, there will be no
limitation on  the  aggregate number  of  shares of  common  stock that  may  be
issuable  upon the conversion,  redemption and/or exercise  of these securities.
Based on the  initial conversion and  exercise prices, which  are, as  described
above, subject to adjustment, the shares of Series A Convertible Preferred Stock
and  Series B Convertible Preferred Stock, the  notes and the warrants issued to
the purchasers  of  the Series  A  Convertible  Preferred Stock,  the  Series  B
Convertible  Preferred Stock  and the  notes are  convertible, redeemable and/or
exercisable for an aggregate of 4,525,642  shares of common stock (exclusive  of
accrued  interest and dividends) (24.8% of  our current outstanding common stock
as of September 30, 2002). Upon the effectiveness of the registration statements
relating to  the Series  A  Convertible Preferred  Stock, Series  B  Convertible
Preferred  Stock and associated warrants and  the notes and associated warrants,
the underlying shares of common stock  will be eligible for immediate resale  in
the  public market. The market price of our securities could fall as a result of
these resales.

     To the extent the holders convert, redeem and exercise, as applicable,  the
Series  A Convertible Preferred Stock, the  Series B Convertible Preferred Stock
and/or the notes and then sell the shares of our common stock they receive,  our
stock price may decrease due to the additional amount of shares available in the
market.  The subsequent sales of these shares could encourage short-sales by our
other shareholders and others that could place further downward pressure on  our
stock  price. Moreover, subject  to the limitations  described above, applicable
law, and as set forth in  the documents governing the transactions, the  holders
of  the Series A Convertible Preferred Stock, the Series B Convertible Preferred
Stock and the  notes may  hedge their  positions in  our stock  by shorting  our
common stock, which could further adversely affect the stock price. Furthermore,
the perception that the holders of the Series A Convertible Preferred Stock, the
Series  B Convertible Preferred Stock and/or the notes may sell short our common
stock may cause others to sell their  shares as well. An increase in the  volume
of  sales of our common stock, whether short  sales or not and whether the sales
are by  the  holders of  Series  A Convertible  Preferred  Stock, the  Series  B
Convertible  Preferred Stock  and the  notes or  others, could  cause the market
price of our  common stock to  decline. The  effect of these  activities on  our
stock  price could increase  the number of  shares required to  be issued on the
next applicable, redemption of the Series B Convertible Preferred Stock and  the
final redemption at maturity of the Series A Convertible Preferred Stock.

               TERMS OF THE SERIES A CONVERTIBLE PREFERRED STOCK,
                     SERIES B CONVERTIBLE PREFERRED STOCK,
                           THE NOTES AND THE WARRANTS

TERMS OF SERIES A CONVERTIBLE PREFERRED STOCK

     The  Series A Convertible Preferred Stock  ranks senior to the common stock
and on  parity with  the Series  B  Convertible Preferred  Stock. The  Series  A
Convertible  Preferred  Stock accrues  per  annum dividends  of  6.5% and  has a
preference on liquidation (or deemed liquidation) equal to $3.92 per share  plus
the amount of accumulated but unpaid dividends.

  CONVERSION

     The Series A Convertible Preferred Stock is convertible in whole or in part
into shares of common stock at the option of the holder at any time.

     The Series A Convertible Preferred Stock is convertible in whole or in part
into shares of common stock at our option if, following the effectiveness of the
registration  statement  described  below  in  "Registration  Requirements," the
closing price of the common stock on  the Nasdaq National Market is above  $6.18
per share for each of the ten consecutive trading days immediately preceding our
notice of conversion. We must exercise our conversion rights with respect to the
Series  A Convertible Preferred Stock simultaneously  and in the same proportion
as we exercise our  conversion rights with respect  to the Series B  Convertible
Preferred Stock.

                                        12


     The  number of shares of common stock  to be issued upon conversion will be
determined by dividing

          (1)  the  principal  amount  being   converted  plus  the  amount   of
     accumulated but unpaid dividends on such shares to be converted, by

          (2) the Series A Conversion Price in effect at the time of conversion.

     Initially,  the "Series A  Conversion Price" is 105%  of the original issue
price of  the Series  A Convertible  Preferred Stock,  or $4.12  per share.  The
Series A Conversion Price and the number of shares of common stock issuable upon
conversion   of  the  Series  A  Convertible  Preferred  Stock  are  subject  to
proportional adjustment upon the occurrence  of certain events, including  stock
splits  and  similar changes  affecting  the common  stock,  and are  subject to
weighted average anti-dilution adjustment in the  event we issue, or are  deemed
to  have issued, shares of common  stock at a price per  share that is less than
the Series  A Conversion  Price then  in effect  (other than  certain  specified
exempt issuances). The Series A Conversion Price may not be adjusted pursuant to
the  weighted average formula to a price that is less than $3.92 per share, that
price being the average of the closing  bid prices of common stock for the  four
trading  days  prior  to  the execution  of  the  securities  purchase agreement
relating to the  Series A Convertible  Preferred Stock and  the trading day  the
binding  agreement was executed, without the  prior approval of our shareholders
in accordance with the Nasdaq Marketplace Rules.

     On the date of  issue, the shares of  Series A Convertible Preferred  Stock
were convertible into 780,086 shares of common stock.

  REDEMPTION

     The Series A Convertible Preferred Stock is subject to mandatory redemption
by  our company, in equal  installments of 1/9 of  the original aggregate shares
issued, at two-month intervals beginning May 2003 and ending September 2004. The
redemption amount we are required to pay will be $3.92 per share to be redeemed,
plus all accrued and unpaid dividends on the redeemed shares.

     The redemption  amount  payable on  any  interim redemption  date  will  be
payable  in shares of common  stock, valued at $3.92 per  share. If, on any such
interim redemption date, $3.92 is higher than the then-current five-day  average
closing bid price of the common stock on Nasdaq, then each holder has the option
to  defer the scheduled interim redemption of such holder's Series A Convertible
Preferred Stock until the next succeeding redemption date. If we are  prohibited
from issuing a sufficient number of shares of common stock to effect any interim
redemption  because  we  have  not obtained  the  approval  of  our shareholders
described below, the shares of Series A Convertible Preferred Stock that  cannot
be  redeemed by the issuance of common stock  must be redeemed by our company in
cash (provided that the notes have been paid in full) or through the issuance of
a subordinated note, at our option. Each subordinated note will have a  one-year
term,  be unsecured, bear interest at 6.5%  per annum and be subordinated to the
notes.

     The redemption amount payable on the final redemption date (the twenty-four
month anniversary of issuance) will be payable, at our option, either in cash or
by the issuance of  shares of common  stock, valued at the  lesser of $3.92  per
share or the then-current five day average closing bid price of the common stock
on  Nasdaq. If the then-current five day average closing bid price of the common
stock on Nasdaq is less than $3.92 and we are prohibited from issuing shares  of
common stock at less than $3.92 because we have not obtained the approval of our
shareholders described below, then we must pay the redemption amount in cash. If
we  are prohibited from  issuing a sufficient  number of shares  of common stock
(because we have already exhausted the 870,693 shares that may be issued without
shareholder approval) to effect the final redemption because it has not obtained
the approval of our shareholders, the  shares of Series A Convertible  Preferred
Stock  that cannot be redeemed by the  issuance of common stock must be redeemed
by our company in cash.

  VOTING

     The holder of each share of  Series A Convertible Preferred Stock have  the
right  to one  vote for  each share  of common  stock into  which such  Series A
Convertible Preferred  Stock could  be  converted on  the  record date  and  are
entitled  to vote upon all  matters upon which holders  of common stock have the
right to

                                        13


vote. In no  event, however,  may any share  of Series  A Convertible  Preferred
Stock entitle the holder to a number of votes that is greater than the number of
votes  the share would  represent if it  was then convertible  into common stock
based on a conversion price of $3.92.  The consent of the holders of a  majority
of  the shares of  Series A Convertible Preferred  Stock outstanding is required
before we may take certain actions,  including the redemption or the payment  of
dividends on the common stock. The holders of the Series A Convertible Preferred
Stock  have agreed that they will not  vote their shares of Series A Convertible
Preferred Stock in connection with the approval of this Proposal One.

TERMS OF SERIES B CONVERTIBLE PREFERRED STOCK

     The Series B Convertible Preferred Stock  ranks senior to the common  stock
and  on  parity with  the Series  A  Convertible Preferred  Stock. The  Series B
Convertible Preferred  Stock accrues  per  annum dividends  of  6.5% and  has  a
preference  on liquidation (or deemed liquidation) equal to $3.60 per share plus
the amount of accumulated but unpaid dividends.

  CONVERSION

     The Series B Convertible Preferred Stock is convertible in whole or in part
into shares of common stock at the option of the holder at any time.

     The Series B Convertible Preferred Stock is convertible in whole or in part
into shares of common stock at our option if, following the effectiveness of the
registration statement described  below under  "Registration Requirements,"  the
closing price of the common stock on Nasdaq is above $5.67 per share for each of
the ten consecutive trading days immediately preceding our notice of conversion.
We  must exercise our conversion rights with respect to the Series B Convertible
Preferred Stock simultaneously  and in the  same proportion as  we exercise  our
conversion rights with respect to the Series A Convertible Preferred Stock.

     The  number of shares of common stock  to be issued upon conversion will be
determined by dividing

          (1)  the  principal  amount  being   converted  plus  the  amount   of
     accumulated but unpaid dividends on such shares to be converted, by

          (2) the Series B Conversion Price in effect at the time of conversion.

     Initially,  the "Series B  Conversion Price" is 105%  of the original issue
price of  the Series  B Convertible  Preferred Stock,  or $3.78  per share.  The
Series B Conversion Price and the number of shares of common stock issuable upon
conversion   of  the  Series  B  Convertible  Preferred  Stock  are  subject  to
proportional adjustment upon the occurrence  of certain events, including  stock
splits  and  similar changes  affecting  the common  stock,  and are  subject to
weighted average anti-dilution adjustment in the  event we issue, or are  deemed
to  have issued, shares of common  stock at a price per  share that is less than
the Series  B Conversion  Price then  in effect  (other than  certain  specified
exempt issuances).

     On  the date of issue,  the shares of Series  B Convertible Preferred Stock
were convertible into 1,242,681 shares of common stock.

  REDEMPTION

     The Series B Convertible Preferred Stock is subject to mandatory redemption
by our company, in  equal installments of 1/9  of the original aggregate  shares
issued, at two-month intervals beginning May 2003 and ending September 2004. The
redemption  amount to  be paid  by our  company will  be $3.60  per share  to be
redeemed, plus all accrued and unpaid dividends on such redeemed shares.

     The redemption amount will be payable in shares of common stock, valued  at
the lesser of

          (1) the Series B Conversion Price then in effect or

          (2)  90% of the average of the daily volume-weighted average prices of
     the common  stock  on  Nasdaq  for  the  twenty  trading  days  immediately
     preceding the date of redemption.

                                        14


     If  we are prohibited from issuing a  sufficient number of shares of common
stock to effect any interim redemption because we have not obtained the approval
of our  shareholders  described  below,  the  shares  of  Series  B  Convertible
Preferred  Stock that cannot be redeemed by the issuance of common stock must be
redeemed by our company in cash (provided that the notes have been paid in full)
or through the issuance of a subordinated note, at our option. Each subordinated
note will have a one-year  term, be unsecured, bear  interest at 6.5% per  annum
and be subordinated to the notes.

  VOTING

     The  shares of Series B Convertible  Preferred Stock have no voting rights,
except that the consent of the holders of  a majority of the shares of Series  B
outstanding  is  required  before we  may  take certain  actions,  including the
redemption or the payment of dividends on the common stock.

  LIMITATIONS ON SERIES A CONVERTIBLE PREFERRED STOCK AND SERIES B CONVERTIBLE
  PREFERRED STOCK SHARES WITHOUT SHAREHOLDER APPROVAL

     Unless we obtain the approval of this Proposal One, we may not take any  of
the  following actions with respect to  the Series A Convertible Preferred Stock
and the Series B Convertible Preferred Stock:

     - may not  issue  more  than  870,693  shares  of  common  stock  upon  the
       conversion  or  redemption of  shares of  Series A  Convertible Preferred
       Stock and Series B Convertible Preferred Stock; and

     - may not issue shares of common stock upon the conversion or redemption of
       shares of Series  A Convertible Preferred  Stock at less  than $3.92  per
       share.

     Under   the  securities  purchase  agreement   relating  to  the  Series  A
Convertible Preferred Stock  and Series  B Convertible Preferred  Stock, we  are
obligated to:

     - prepare and file this proxy statement on or before October 25, 2002;

     - use  all reasonable efforts to obtain the approval of our shareholders to
       this Proposal One on or before February 28, 2003; and

     - in any event, seek the approval of our shareholders to this Proposal  One
       no later than our 2003 Annual Meeting of Shareholders.

  WARRANTS

     In connection with the sale of the Series A Convertible Preferred Stock and
Series  B Convertible Preferred  Stock, we issued warrants  to the purchasers of
the Series  A Convertible  Preferred Stock  and Series  B Convertible  Preferred
Stock  to purchase in whole or in part  an aggregate of 709,528 shares of common
stock at an exercise price of $4.51 per share. These warrants are exercisable at
any time after  the six-month anniversary  of the  issue date and  prior to  the
four-year  anniversary of the issue  date. The number of  shares of common stock
for which  these  warrants are  exercisable  and  the exercise  price  of  these
warrants  are subject  to proportional adjustment  for stock  splits and similar
changes affecting the common stock. The exercise price of these warrants is also
subject to weighted average anti-dilution adjustment  in the event we issue,  or
are  deemed to have issued, shares of common  stock at a price per share that is
less than the exercise price then in effect (other than certain specified exempt
issuances) except that the  exercise price may not  be adjusted pursuant to  the
weighted  average formula to a  price that is less than  the market value of our
common stock as of the  date of issuance of these  warrants (that is, $3.92  per
share).

  REGISTRATION REQUIREMENTS

     We  also  entered into  with  the purchasers  of  the Series  A Convertible
Preferred Stock and Series B  Convertible Preferred Stock a registration  rights
agreement,  under which  we agreed  to prepare  and file  within 30  days of the
closing date  a registration  statement covering  the resale  of the  shares  of
common  stock  issuable  upon  the  conversion or  redemption  of  the  Series A
Convertible Preferred Stock  and Series  B Convertible Preferred  Stock and  the
exercise  of the associated warrants. We  filed the registration statements in a
timely

                                        15



fashion,  and they were  declared effective by  the SEC on  October 24, 2002. In
addition,  we  agreed  to  prepare,  file  and  seek  the  effectiveness  of   a
registration  statement covering  the resale  of up  to an  additional 2,000,000
shares of  common stock  held by  Antonio R.  Sanchez, Jr.,  a director  of  our
company,  and George W. Haywood, and an IRA for the benefit of Mr. Haywood, upon
their request  no  sooner than  nine  months after  the  date of  the  agreement
relating  to the purchase of the Series A Convertible Preferred Stock and Series
B Convertible Preferred Stock.


  TRADING RESTRICTIONS

     So long as  any of  the notes or  associated warrants  described below  are
outstanding,  a purchaser  of Series A  Convertible Preferred Stock  or Series B
Convertible Preferred Stock may not engage in a short sale or establish an  open
put  equivalent position with respect to a number of shares of common stock that
is greater than

          (1) the number  of shares  of common  stock for  which the  associated
     warrant  held  by  the purchaser  is  then exercisable  (without  regard to
     limitations on exercisability) plus

          (2) the number  of shares of  common stock issuable  to the  purchaser
     pursuant  to  a notice  of  conversion of  shares  of Series  A Convertible
     Preferred Stock or  Series B Convertible  Preferred Stock, or  a notice  of
     exercise  of an associated warrant, delivered to  us no later than the next
     succeeding business day.

TERMS OF THE NOTES

  INTEREST AND REPAYMENT TERMS

     The notes  bear interest  at the  rate of  6.5% per  annum. The  notes  are
payable  in  six  consecutive  monthly installments  of  $500,000  (plus accrued
interest) each beginning in January 2003 and a final payment of $5,000,000 (plus
accrued interest) in October 2003.

  PREPAYMENT

     We may prepay the notes at any time by the payment of 105% of the principal
amount being prepaid, plus all accrued interest thereon. Our right of to  prepay
the  notes is subject  to the satisfaction of  certain conditions, including the
listing of the  common stock on  Nasdaq, the effectiveness  of the  registration
statement described below in "Registration Requirements", and the absence of any
default  by us under the securities purchase agreement related to the notes, the
notes, the associated warrants and  the registration rights agreement  described
below. Our prepayment of the notes is also subject to the right of the holder to
convert  any portion of the notes for which we have given a notice of prepayment
into shares of common stock, in the manner described below.

  CONVERSION

     The  unpaid  principal  amount  and  accrued  interest  of  each  note   is
convertible in whole or in part into shares of common stock at the option of the
holder at any time.

     The   unpaid  principal  amount  and  accrued  interest  of  each  note  is
convertible in whole or in  part into shares of common  stock at our option  if,
following  the tenth  trading day  after the  effectiveness of  the registration
statement described below,  the weighted average  price of the  common stock  on
Nasdaq  is at  or above  $4.54 per  share for  the ten  consecutive trading days
immediately preceding our notice of conversion.  Our right to convert the  notes
is also subject to the satisfaction of certain conditions, including the listing
of  the common stock on Nasdaq,  the effectiveness of the registration statement
described below  and  the  absence of  any  default  by our  company  under  the
securities  purchase agreement relating to the  notes, the notes, the associated
warrants and the registration rights agreement described below. If following our
notice of conversion  the weighted average  price of the  common stock does  not
continue  to exceed the initial note conversion price of $3.78 per share through
the mandatory conversion  date, then a  pro-rata portion of  the selected  notes
will  be  required to  be converted  based on  the number  of days  the weighted
average price of the
                                        16


common stock did exceed the initial note conversion price. The minimum principal
amount of  notes  that we  may  convert is  the  lesser of  $1,000,000  and  the
aggregate principal amount outstanding under the notes.

     The  number of shares of common stock  to be issued upon conversion will be
determined by dividing

          (1) the portion of the unpaid principal amount and accrued interest of
     the note being converted, by

          (2) the note conversion price in effect at the time of conversion.

     Initially, the  "Note  Conversion  Price"  is $3.78  per  share.  The  Note
Conversion  Price  and  the  number  of shares  of  common  stock  issuable upon
conversion of the notes are subject to proportional adjustment for stock  splits
and  similar  changes  affecting  the  common  stock  and  are  subject  to full
anti-dilution adjustment in the  event we issue, or  are deemed to have  issued,
shares  of  common  stock at  a  price per  share  that  is less  than  the Note
Conversion Price then in effect (other than certain specified exempt  issuances,
including  any issuance of common stock upon the conversion or redemption of the
Series A  Convertible Preferred  Stock  or the  Series B  Convertible  Preferred
Stock).

     Notwithstanding  the foregoing,  no holder of  the notes  or the associated
warrants is entitled to convert the notes or exercise the associated warrants to
the extent that such conversion or exercise would result in such person and  its
affiliates  being the holders of  more than 4.99% of  the shares of common stock
outstanding after giving effect to the conversion or exercise. This  restriction
does  not prohibit  a holder from  converting or  exercising up to  4.99% of the
shares then  outstanding, then  selling  those shares  and later  converting  or
exercising up to 4.99% again.

     In  addition to the  redemption rights described below,  the holders of the
notes are entitled to receive from  our company substantial cash damages in  the
event we fail to timely honor a notice of conversion tendered by a holder.

     On  the date of issue, the notes  were convertible into 2,116,402 shares of
common stock.

  FORCED REDEMPTION

     If we are prohibited from issuing  a sufficient number of shares of  common
stock to effect any attempted conversion of the notes by a holder because it has
not  obtained the approval of our shareholders to this Proposal One, each holder
of a note will have the right to redeem all or a portion of the principal amount
outstanding thereunder that cannot be converted for a cash payment equal to 100%
of the principal amount being redeemed, plus all accrued interest thereon.

     If we fail  to have  the registration statement  described below  effective
prior  to the  fifth business  day preceding the  date of  any scheduled payment
under the notes (with the first  scheduled payment date being January 1,  2003),
each  holder of a  note will have the  right to redeem  such holder's portion of
such scheduled payment, or any portion thereof, for a cash payment equal to  the
principal amount being redeemed and all accrued interest thereon, divided by the
Note Conversion Price then in effect and multiplied by the daily volume-weighted
average  price of  the common  stock on  Nasdaq on  the trading  day immediately
preceding the date of such failure.

     Upon the occurrence of other "Triggering Events" (as defined in the notes),
each holder of a  note will have  the right to  redeem all or  a portion of  the
principal  amount outstanding thereunder for a  cash payment that is the greater
of

          (1) 125%  of the  principal amount  being redeemed,  plus all  accrued
     interest thereon, and

          (2)  the  principal amount  being  redeemed and  all  accrued interest
     thereon, divided by the Note Conversion Price then in effect and multiplied
     by the daily volume-weighted average price of the common stock on Nasdaq on
     the trading day immediately preceding such Triggering Event.

                                        17


     Other Triggering Events include, but are not limited to, our failure to

     - make a scheduled payment under the notes when due,

     - timely honor a notice of conversion, to list the common stock  underlying
       the notes and associated warrants for specified periods, and

     - to have the registration statement described below effective prior to the
       135th day following the issuance of the notes.

     Upon  the occurrence of  a "Change of  Control" (as defined  in the notes),
each holder of a  note will have  the right to  redeem all or  a portion of  the
principal  amount outstanding thereunder for a  cash payment that is the greater
of

          (1) 115%  of the  principal amount  being redeemed,  plus all  accrued
     interest thereon, and

          (2)  the  principal amount  being  redeemed and  all  accrued interest
     thereon, divided by the Note Conversion Price then in effect and multiplied
     by the average of  the daily volume-weighted average  prices of the  common
     stock  on Nasdaq for the five trading days immediately preceding the notice
     of redemption.

  DEFAULTS AND REMEDIES

     The notes  contain "Events  of  Default" (as  defined  in the  notes)  that
include, but are not limited to,

     - our failure to make required cash payments under the notes when due,

     - our failure to abide by the cash maintenance requirements described below
       under "Security Agreement,"

     - the existence of certain insolvency or bankruptcy events, and

     - the  existence of certain defaults  by or claims against  us in excess of
       $100,000.

Upon an Event of Default,  each holder of a note  is entitled to accelerate  all
amounts due thereunder, to assess interest at a default rate and to exercise any
other  right  or  remedy  available under  the  notes,  the  securities purchase
agreement relating  to the  notes  or applicable  law. If  we  fail to  pay  any
accelerated  amounts to  the holder  within five days,  the holder  may void the
acceleration and cause the Note  Conversion Price to be  reset to the lesser  of
the  Note Conversion Price  then in effect and  the lowest daily volume-weighted
average price of the common stock on Nasdaq during the period that  acceleration
amounts were due and payable to the holder.

  SECURITY AGREEMENT

     We  and an agent  for the purchasers  of the notes  entered into a security
agreement, pursuant to  which the notes  have been secured  by a first  priority
lien  in  virtually  all of  our  assets (including,  without  limitation, cash,
accounts  receivable,  equipment  and  intangibles).  The  securities   purchase
agreement  relating  to  the  notes  requires  us  to  maintain  cash  and  cash
equivalents in accounts  pledged under the  security agreement in  an amount  at
least  equal to  the lesser of  $5,000,000 and the  aggregate amount outstanding
under the notes. The  securities purchase agreement relating  to the notes  also
places  limitations on the amount of cash  that we can maintain in accounts that
are not pledged under the security agreement.

  RESTRICTIONS ON OUR COMPANY

     The terms  of the  notes strictly  prohibit additional  "Indebtedness"  (as
defined  in  the  notes)  that  may  be  incurred  by  us  while  the  notes are
outstanding, as described in general terms below.

     Payments of principal and  interest and other amounts  due under the  notes
cannot  be subordinated to any other obligations  of our company. For so long as
the notes are outstanding, in the event  we incur any debt (including any  notes
issuable  upon the redemption of shares  of Series A Convertible Preferred Stock
or Series B  Convertible Preferred Stock),  the lender must  first enter into  a
subordination agreement with

                                        18


purchasers  of the notes pursuant to which the indebtedness owed to such lenders
will be  subordinated  in full  to  the notes.  The  form of  the  subordination
agreement will either be in the form attached to our current report on Form 8-K,
dated  September 20,  2002, as  an exhibit or  otherwise will  contain terms and
conditions acceptable to the purchasers of the notes.

     While the notes are outstanding, we may not redeem or otherwise acquire any
of our  capital stock  (other  than pursuant  to the  terms  of the  notes,  the
warrants,  the Series A Convertible Preferred Stock and the Series B Convertible
Preferred Stock)  without  the  consent  of the  note  holders.  Generally,  any
permitted  redemption of the Series A Convertible Preferred Stock and the Series
B Convertible Preferred Stock may  only be paid in  shares of our common  stock.
The  note holders  are entitled to  receive any dividends  paid or distributions
made on the common stock to the same extent as though the holders had  converted
the notes in full into shares of common stock.

  VOTING

     The  notes do not entitle  their holders to any right  to vote with the our
shareholders.

  WARRANTS

     In connection  with  the sale  of  the notes,  we  issued warrants  to  the
purchasers  of the notes to purchase in whole or in part an aggregate of 386,473
shares of common stock at an exercise  price of $4.14 per share. These  warrants
are  exercisable at any  time prior to  the three-year anniversary  of the issue
date. The  number  of  shares of  common  stock  for which  these  warrants  are
exercisable and the exercise price of these warrants are subject to proportional
adjustment  for stock splits and similar  changes affecting the common stock and
are subject to full anti-dilution adjustment in  the event the we issue, or  are
deemed  to have issued, shares of common stock at a price per share that is less
than the exercise  price then  in effect  (other than  certain specified  exempt
issuances,  including  any  issuance  of common  stock  upon  the  conversion or
redemption of  the  Series  A  Convertible  Preferred  Stock  or  the  Series  B
Convertible Preferred Stock).

     If  we are prohibited from issuing a  sufficient number of shares of common
stock in connection with any attempted exercise of the warrants because we  have
not  obtained the approval of our shareholders described below, a warrant holder
will have the  right to require  us to pay  a cash payment  with respect to  the
portion  of the warrant sought  to be exercised equal  to the difference between
the warrant exercise price and the  volume-weighted average price of the  common
stock on Nasdaq as of the time of the attempted exercise.

     Notwithstanding  the foregoing,  no holder of  the notes  or the associated
warrants is entitled to convert the notes or exercise the associated warrants to
the extent that such conversion or exercise would result in such person and  its
affiliates  being the holders of  more than 4.99% of  the shares of common stock
outstanding after giving effect to the conversion or exercise. This  restriction
does  not prohibit  a holder from  converting or  exercising up to  4.99% of the
shares then  outstanding, then  selling  those shares  and later  converting  or
exercising up to 4.99% again.

  LIMITATIONS ON NOTES WITHOUT SHAREHOLDER APPROVAL

     As  required by the Nasdaq Marketplace Rules, unless we obtain the approval
of this Proposal  One, we may  not issue  more than 2,753,163  shares of  common
stock  upon the conversion  or redemption of  the notes and  the exercise of the
associated warrants. Under  the securities  purchase agreement  relating to  the
notes, we are obligated to:

     - prepare  and file with the SEC this  proxy statement on or before October
       25, 2002;

     - use all reasonable efforts to obtain the approval of our shareholders  to
       this Proposal One on or before February 28, 2003; and

     - in  any event, seek the approval of our shareholders of this Proposal One
       no later than our 2003 Annual Meeting of Shareholders.

                                        19


  REGISTRATION REQUIREMENTS

     We and  the purchasers  of the  notes entered  into a  registration  rights
agreement,  under which  we agreed  to prepare  and file  within 20  days of the
closing date a registration statement covering the resale of 110% of the  shares
of  common stock issuable upon  the conversion of the  notes and the exercise of
the associated warrants. We filed the registration statement in a timely fashion
and it was declared effective by the SEC on October 24, 2002.

     In  addition  to  the  redemption  rights  described  above  under  "Forced
Redemption,"  the  holders  of  the  notes  are  entitled  to  receive  from  us
substantial cash  damages  in  the  event  we  fail  to  file  the  registration
statement,  or have  the registration  statement declared  effective, within the
time limits set forth above or,  thereafter, to keep the registration  statement
effective for certain periods of time.

     The  foregoing  description of  the Series  A Convertible  Preferred Stock,
Series B Convertible Preferred Stock, the  notes and the associated warrants  is
qualified  by reference  to the documents  that are  filed as an  exhibit to our
Current Report  on Form  8-K,  dated September  20,  2002, and  incorporated  by
reference.

  TRADING RESTRICTIONS

     The  holders of the notes have also  agreed to the following limitations on
trading in connection with their purchase of the notes and associated  warrants.
So  long as a  holder holds any notes  or associated warrants, he  or it may not
engage in a short sale or establish an open put equivalent position with respect
to a number of shares of common stock that is great than:

     - the number of shares of common stock  for which the warrants held by  him
       or   it  are   then  exercisable   (without  regard   to  limitations  on
       exercisability); plus

     - the number of shares of common stock issuable to him or it under a notice
       of conversion  of  the  notes  or notice  of  exercise  of  the  warrants
       delivered to us no later than the next succeeding business day.

     These limitations terminate upon the occurrence of a "Triggering Event," an
"Event  of Default," or the consummation or  public announcement of a "Change of
Control," in each case, as such terms are defined in the notes.

                      WHERE YOU CAN FIND MORE INFORMATION

     The terms of the Series A Convertible Preferred Stock, Series B Convertible
Preferred Stock, the  notes and  the associated  warrants are  complex and  only
briefly  summarized in this proxy statement.  If you would like more information
concerning the rights, preferences and terms of these securities, please see the
documents filed as exhibits to our Current Report on Form 8-K filed with the SEC
on September 20, 2002.

     In connection  with our  issuance  of the  Series A  Convertible  Preferred
Stock,  Series  B  Convertible Preferred  Stock,  the notes  and  the associated
warrants, we have filed registration statements on Form S-3 with the SEC,  which
were  declared  effective by  the SEC  on October  24, 2002.  These registration
statements cover the resale of up to 5,666,490 shares of common stock that would
potentially become issuable upon  the conversion or redemption  of the Series  A
Convertible Preferred Stock, Series B Convertible Preferred Stock, the notes and
upon exercise of the associated warrants, and accrued interest and dividends. We
may  be  required from  time  to time  to  register additional  shares  for such
purposes due to declines in the trading price of our common stock.
