ITEM 5.  OTHER EVENTS.

The Financing

On July 7, 1999, Worldtalk  Communications  Corporation,  a Delaware corporation
doing business as Worldtalk Corporation ("Registrant" or the "Company"), entered
into an  agreement  for the sale of shares of Common  Stock (the  "Shares")  and
warrants for the purchase of Common Stock (the "Warrants") to certain affiliates
of  Hilal  Capital  Management  LLC and  others  (the  "Investors").  Under  the
agreement,  the Shares and the  Warrants  were  placed in escrow  until  certain
conditions  were  satisfied,  which  occurred on July 19, 1999.  On that date, a
total of 3,333,334  Shares for a purchase  price of $3.00 per share and Warrants
for the  purchase  of up to  1,666,667  additional  shares of Common  Stock were
delivered to the Investors. A total of $10,000,000 was raised as a result of the
sale of the Shares and the Warrants (the "Financing").

The Shares,  the  Warrants and the Common Stock  issuable  upon  exercise of the
Warrants (the "Warrant  Shares") have not been  registered  under the Securities
Act of  1933,  and  may not be  offered  or sold  in the  United  States  absent
registration  or an exemption from  applicable  registration  requirements.  The
Investors were provided with certain  registration rights relating to the Shares
and the Warrant Shares.  Each Investor was also granted the right to participate
in any new financing of the Company to the extent of the  Investor's  percentage
ownership.

At  the  completion  of  the  Financing  on  July  19,  1999,  the  Company  had
approximately  14,280,500  shares of Common  Stock issued and  outstanding.  The
Preferred  Stock remains  undesignated  and,  therefore,  no shares of Preferred
Stock are  outstanding.  The  Investors as a group  currently  hold 23.3% of the
issued and outstanding  shares of Common Stock. The only Investor who holds more
than 5% of the issued and outstanding  Common Stock is Hilal Capital  Associates
LLC,  with 8.37%.  On a fully diluted  basis,  treating all warrants and options
outstanding as if exercised, the Investors would hold approximately 27.1% of the
issued and  outstanding  capital  stock of the Company at the  completion of the
Financing.

The Nasdaq Stock Market Hearing

Representatives of the Company met with a Nasdaq Listing Qualifications Panel at
a hearing on July 8, 1999 to discuss  the  Company's  failure to meet The Nasdaq
Stock  Market's net tangible  assets  requirement  for continued  listing on the
Nasdaq National Market. As a result of the hearing, the Financing and the filing
of this Current Report on Form 8-K showing pro forma tangible net assets at June
30, 1999 of at least  $11,500,000,  the Company has been  informed by The Nasdaq
Stock Market that the Company's  listing on the Nasdaq  National  Market will be
continued.

                  WHEREAS:

                  A. The Company  and the Buyers are  executing  and  delivering
this  Agreement in reliance  upon the  exemption  from  securities  registration
afforded by Rule 506 of  Regulation D  ("Regulation  D") as  promulgated  by the

                  B. The  Company  has  authorized  the  issuance  of between $5

                  C. The Company has  authorized  the  issuance of Common  Stock
Purchase Warrants (the "Warrants"), in the form attached hereto as Exhibit B, to

subject to adjustment as provided in the Warrants; and

                  E.  Contemporaneously  with the execution and delivery of this
Agreement, the parties hereto are executing and delivering a Registration Rights

                  NOW,  THEREFORE,  the Company and the Buyers  hereby  agree as
follows.


<PAGE>

                  1.       INITIAL PURCHASE AND SALE OF COMMON STOCK.

                           a. Initial  Purchase of Common Stock.  Subject to the
satisfaction  (or waiver) of the conditions set forth in Sections 7 and 8 below,
the  Company  shall issue and sell to the Buyers and the Buyers  shall  purchase
from the Company an  aggregate of not less than $5 million and not more than $10
million of Common Stock (the "Initial Purchase Price") in the respective amounts
as are set forth  opposite  each  Buyer's  name on the  Schedule of Buyers at an
initial  closing (the  "Initial  Closing").  The per share  purchase  price (the
"Purchase  Price") of the Common  Stock shall be $3.00.  On the Initial  Closing
Date  (as  defined  below)  the  Company  shall  deliver  to each  Buyer a stock
certificate  representing  the  number  of  shares  which  such  Buyer  is  then
purchasing (as indicated  opposite such Buyer's name on the Schedule of Buyers),
duly executed on behalf of the Company and  registered in the name of such Buyer
or its designee (the "Stock Certificates").

                           b.  Initial  Closing  Date.  The date and time of the
Initial Closing (the "Initial Closing Date") shall be 5:00 p.m. Eastern Standard
Time on July 7, 1999, subject to notification of satisfaction (or waiver) of the
conditions  to the  Closing  set forth in  Sections 7 and 8 below (or such later
date as is mutually  agreed to by the Company  and Hilal).  The Initial  Closing
shall occur on the Initial  Closing  Date at the offices of Schulte Roth & Zabel
LLP, 900 Third Avenue, New York, New York 10022.  Notwithstanding the foregoing,
if on the Initial Closing Date all of the conditions set forth in Sections 7 and
8 are satisfied  except for the condition in Section 8(b), such closing shall be
made into escrow pursuant to the terms of Escrow Agreement  annexed as Exhibit D
(the  "Escrow  Agreement")  and  other  appropriate  escrow  documents,  pending
satisfaction  of such remaining  condition not later than July 14, 1999 (or such
later date as is mutually  agreed to by the Company and Hilal).  In the event of
such escrow closing,  the Initial Closing (and the sale of the securities) shall
not be deemed to have been  completed  unless and until the condition in Section
8(b) is  satisfied  in  accordance  with  the  terms  hereof  and of the  Escrow
Agreement,  but if such condition is timely satisfied,  the Initial Closing Date
shall be deemed the date of deposit into escrow.

                           c.  Form of  Payment.  On the  Initial  Closing  Date
(subject to escrow,  if applicable),  each Buyer shall pay the Purchase Price to
State  Street  for the  Common  Stock to be issued and sold to such Buyer at the
Initial Closing,  by wire transfer of immediately  available funds in accordance
with the Company's written wire  instructions  provided in writing to the Buyers
at least two days prior to the Initial Closing Date.

                           d. Warrants.  In consideration of the purchase of the
Common Stock,  the Company shall on the Initial Closing Date (subject to escrow,
if  applicable)  issue and  deliver  to each  Buyer,  Warrants  to  purchase  an
additional  number of shares of Common  Stock  equal to  one-half  the number of
shares of Common Stock that the Buyer purchases at the Initial Closing.

                  2.       SECOND PURCHASE AND SALE OF COMMON STOCK.

                           a. Second  Purchase of Common Stock. If so elected by
Hilal in its sole discretion, and subject to the satisfaction (or waiver) of the
conditions set forth in Sections 7 and 8 below, the Company shall issue and sell
to such  additional  Buyers as may be  designated by


                                      -2-
<PAGE>

Hilal and such Buyers shall  purchase from the Company at a second  closing (the
"Second  Closing"  and,  together  with the  Initial  Closing,  the  "Closings")
additional  shares of Common  Stock,  at the Purchase  Price,  provided that the
aggregate  amount  of  Common  Stock so  purchased  shall  not be more  than the
difference  between $10 million and the aggregate purchase price of Common Stock
purchased at the Initial Closing.  On the Second Closing Date (as defined below)
the Company  shall deliver to each such Buyer a stock  certificate  representing
the number of shares that such Buyer is then  purchasing (as indicated  opposite
such  Buyer's  name on the Schedule of Buyers,  as  amended),  duly  executed on
behalf of the Company and registered in the name of such Buyer or its designee.

                           b.  Second  Closing  Date.  The  date and time of the
Second Closing (the "Second Closing Date" and, together with the Initial Closing
Date,  the "Closing  Dates")  shall be 10:00 a.m.  Eastern  Standard Time on the
fifth  business day following the later of July 7, 1999 or, if  applicable,  the
release of the escrow  closing  upon timely  satisfaction  of the  condition  in
Section  8(b),  but not later  than July 21,  1999,  subject  to the  continuing
satisfaction  (or waiver) of the  conditions set forth in Sections 7 and 8 below
(or such later date as is mutually  agreed to by the  Company  and  Hilal).  The
Second  Closing shall occur on the Second Closing Date at the offices of Schulte
Roth & Zabel LLP, 900 Third Avenue,  New York,  New York 10022.  Notwithstanding
the foregoing,  if on the Second Closing Date all of the conditions set forth in
Sections 7 and 8 are satisfied  except for the  condition in Section 8(b),  such
closing  shall be made into escrow  pursuant to the Escrow  Agreement  and other
appropriate escrow documents,  pending  satisfaction of such remaining condition
not later than July 14, 1999 (or such later date as is mutually agreed to by the
Company and Hilal). In the event of such escrow closing, the Second Closing (and
the sale of the  securities)  shall not be deemed to have been completed  unless
and until the  condition in Section 8(b) is  satisfied  in  accordance  with the
terms  hereof  and of the  Escrow  Agreement,  but if such  condition  is timely
satisfied,  the Second  Closing  Date  shall be deemed the date of deposit  into
escrow.

                           c.  Form  of  Payment.  On the  Second  Closing  Date
(subject to escrow,  if applicable),  each Buyer at the Second Closing shall pay
the Company  the  Purchase  Price for the Common  Stock to be issued and sold to
such Buyer at the Second  Closing,  by wire  transfer of  immediately  available
funds in accordance  with the Company's  written wire  instructions  provided in
writing to Hilal at least two days prior to the Second Closing Date.

                           d. Warrants.  In consideration of the purchase of the
additional  Common Stock,  the Company shall on the Second Closing Date (subject
to  escrow,  if  applicable),  issue and  deliver  to each  Buyer at the  Second
Closing,  Warrants to purchase an  additional  number of shares of Common  Stock
equal to one-half the number of shares of Common Stock that such Buyer purchases
at the Second Closing.

                  3.       BUYER'S REPRESENTATIONS AND WARRANTIES.

                  Each  Buyer  (including  each Buyer  purchasing  at the Second
Closing) represents and warrants with respect to only itself that:


                                      -3-
<PAGE>

                           a. Investment  Purpose.  Such Buyer (i) is purchasing
the Common Stock and the Warrants and (ii) upon exercise of the  Warrants,  will
acquire the Warrant Shares then issuable for its own account for investment only
and not with a present  view  towards,  or for resale in  connection  with,  the
public  sale or  distribution  thereof;  provided,  however,  that by making the
representations herein, such Buyer does not agree to hold any Securities for any
minimum  or other  specific  term and  reserves  the  right  to  dispose  of the
Securities  at any  time  in  accordance  with  or  pursuant  to a  registration
statement or an exemption under the 1933 Act.

                           b.  Accredited  Investor  Status.  Such  Buyer  is an
"accredited investor" as that term is defined in Rule 501(a) of Regulation D.

                           c.  Reliance on  Exemptions.  Such Buyer  understands
that the Common Stock and Warrants are being  offered and sold to it in reliance
on specific  exemptions  from the  registration  requirements  of United  States
federal and state  securities  laws and that the Company is relying in part upon
the  truth  and   accuracy   of,  and  such   Buyer's   compliance   with,   the
representations,  warranties, agreements,  acknowledgments and understandings of
such  Buyer set forth  herein in order to  determine  the  availability  of such
exemptions and the eligibility of such Buyer to acquire the Common Stock and the
Warrants.

                           d. Information.  Such Buyer and its advisors, if any,
have been  furnished with all materials  relating to the business,  finances and
operations  of the Company and  materials  relating to the offer and sale of the
Common Stock and the  Warrants  which have been  requested  by such Buyer.  Such
Buyer and its  advisors,  if any,  have been  afforded  the  opportunity  to ask
questions of the Company.  Neither such  inquiries  nor any other due  diligence
investigations  conducted  by  such  Buyer  or  its  advisors,  if  any,  or its
representatives  shall modify, amend or affect such Buyer's right to rely on the
Company's representations and warranties contained in Section 3 below.

                           e. No  Governmental  Review.  Such Buyer  understands
that no  United  States  federal  or state  agency or any  other  government  or
governmental  agency has passed on or made any  recommendation or endorsement of
the  Securities  or  the  fairness  or  suitability  of  the  investment  in the
Securities nor have such  authorities  passed upon or endorsed the merits of the
offering of the Securities.

                           f. Transfer or Resale.  Such Buyer  understands  that
except as provided in the Registration Rights Agreement: (i) the Securities have
not been and are not being registered under the 1933 Act or any state securities
laws, and may not be offered for sale, sold,  assigned or transferred unless (A)
subsequently  registered thereunder,  (B) such Buyer shall have delivered to the
Company an opinion of counsel,  in a generally  acceptable  form,  to the effect
that such Securities to be sold,  assigned or transferred may be sold,  assigned
or  transferred  pursuant to an exemption  from such  registration,  or (C) such
securities can be sold, assigned or transferred pursuant to Rule 144 promulgated
under the 1933 Act (or a successor rule thereto) ("Rule 144");  (ii) any sale of
such securities made in reliance on Rule 144 may be made only in accordance with
the terms of Rule 144 and further, if Rule 144 is not applicable,  any resale of
such securities  under  circumstances in which the seller (or the person through
whom the sale is


                                      -4-
<PAGE>

made) may be deemed to be an  underwriter  (as that term is  defined in the 1933
Act) may require  compliance with some other exemption under the 1933 Act or the
rules and regulations of the SEC  thereunder;  and (iii) neither the Company nor
any other person is under any obligation to register such  securities  under the
1933 Act or any state securities laws or to comply with the terms and conditions
of any exemption thereunder.

                           g.   Legends.   Such  Buyer   understands   that  the
certificates or other instruments  representing the Securities,  and, until such
time as the sale of the Securities  have been  registered  under the 1933 Act as
contemplated by the  Registration  Rights  Agreement,  the certificates or other
documents  representing the Securities,  except as set forth below, shall bear a
restrictive  legend in  substantially  the following  form (and a  stop-transfer
order may be placed against transfer of such certificates or other documents):

         THE  SECURITIES   REPRESENTED  BY  THIS  [CERTIFICATE]  HAVE  NOT  BEEN
         REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS AMENDED,  OR ANY STATE
         SECURITIES  LAWS.  THE  SECURITIES  MAY NOT BE OFFERED FOR SALE,  SOLD,
         TRANSFERRED  OR ASSIGNED IN THE  ABSENCE OF AN  EFFECTIVE  REGISTRATION
         STATEMENT  FOR THE  SECURITIES  UNDER THE  SECURITIES  ACT OF 1933,  AS
         AMENDED,  OR  APPLICABLE  STATE  SECURITIES  LAWS,  OR  PURSUANT  TO AN
         APPLICABLE  EXEMPTION TO THE REGISTRATION  REQUIREMENTS OF SUCH ACT AND
         SUCH LAWS.

The legend  set forth  above  shall be removed  and the  Company  shall  issue a
certificate without such legend to the holder of any Securities upon which it is
stamped,  if (i) any such Securities are registered for sale under the 1933 Act,
(ii) in connection  with a sale  transaction,  such holder  provides the Company
with an opinion of counsel, in a generally acceptable form, to the effect that a
public sale, assignment or transfer of any of the Securities may be made without
registration  under the 1933 Act,  or (iii)  any of the  Securities  can be sold
pursuant  to Rule 144  without any  restriction  as to the number of  securities
acquired as of a particular  date that can then be immediately  sold. Each Buyer
acknowledges,  covenants and agrees to sell any of the Securities from which the
legend has been removed only pursuant to (i) a registration  statement effective
under the 1933 Act,  or (ii)  advice of  counsel  that such sale is exempt  from
registration  required  by  Section  5 of the 1933  Act.  In the event the above
legend is removed from any of the  Securities,  the Company may, upon reasonable
advance notice to the holder,  require that the above legend be placed on any of
the  Securities  that cannot then be sold pursuant to an effective  registration
statement or Rule 144(k) under the 1933 Act (or any successor rule thereto).

                           h. Authorization;  Enforcement.  This Agreement,  the
Warrant  and the  Registration  Rights  Agreement  have  been  duly and  validly
authorized,  executed  and  delivered on behalf of such Buyer and is a valid and
binding  agreement of such Buyer enforceable in accordance with their respective
terms,  subject  as to  enforceability  to general  principles  of equity and to
applicable bankruptcy, insolvency,  reorganization,  moratorium, liquidation and
other  similar laws  relating to, or affecting  generally,  the  enforcement  of
applicable creditors' rights and remedies.

                           i. Residency.  Such Buyer is a resident of the United
States of America.

                  4.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

                           The Company  represents  and  warrants to each of the
Buyers, except as disclosed in the letter from the Company to the Buyers of even
date herewith containing certain disclosures (the "Disclosure Letter"), that:

                           a.  Organization and  Qualification.  The Company and
its sole subsidiary,  Deming Software, Inc., are corporations duly organized and
validly  existing in good standing under the laws of the  jurisdiction  in which
they are  incorporated,  and have the  requisite  corporate  power to own  their
properties  and to carry on their business as now being  conducted.  Each of the
Company and its  subsidiary  is duly  qualified as a foreign  corporation  to do
business and is in good  standing in every  jurisdiction  in which the nature of
the business conducted by it makes such qualification  necessary,  except to the
extent that the failure to be so qualified or be in good standing would not have
a Material Adverse Effect.  "Material Adverse Effect" means any material adverse
effect on (i) the  business,  properties,  operations,  condition  (financial or
otherwise),   results  of  operations  or  prospects  of  the  Company  and  its
subsidiary,  taken as a whole,  or (ii) on the ability of the Company to perform
its  obligations  hereunder or under the agreements or instruments to be entered
into or filed in connection herewith, or under the Securities.

                           b. Authorization;  Enforcement; Compliance with Other
Instruments.  (i) The Company has the requisite corporate power and authority to
enter into and perform its obligations under this Agreement, the Warrant and the
Registration Rights Agreement (collectively, the "Closing Agreements"), to issue
and sell the Common Stock in accordance with the terms hereof,  and to issue the
Warrant Shares upon the exercise of the Warrants,  in accordance  with the terms
and  conditions of the Warrants,  (ii) the execution and delivery of the Closing
Agreements  by the  Company  and  the  consummation  by it of  the  transactions
described herein and therein, including, without limitation, the issuance of the
Common Stock and the Warrants and the  reservation for issuance and the issuance
of the Warrant Shares upon exercise of the Warrants have been duly authorized by
the Company's  Board of Directors  and no further  consent or  authorization  is
required by the Company,  its Board of Directors or its  stockholders  under the
Delaware General Corporation Law, the Company's  Certificate of Incorporation or
otherwise,  and,  (iii) the  Closing  Agreements  have been  duly  executed  and
delivered by the Company,  and constitute  the valid and binding  obligations of
the Company  enforceable  against the Company in  accordance  with their  terms,
except as such  enforceability may be limited by general principles of equity or
applicable bankruptcy,  insolvency,  reorganization,  moratorium, liquidation or
similar laws relating to, or affecting generally,  the enforcement of creditors'
rights and remedies.

                           c.  Capitalization  and Indebtedness.  As of the date
hereof,  the  authorized  capital  stock of the Company  consists of  25,000,000
shares of Common  Stock,  of which as of the date hereof  10,947,188  shares are
issued and outstanding,  and 6,500,000 shares


                                      -6-
<PAGE>

of Preferred  Stock, par value $.01 per share (the "Preferred  Stock"),  none of
which as of the date hereof are issued or  outstanding.  All of the  outstanding
shares  of  Common  Stock  have  been  validly  issued  and are  fully  paid and
nonassessable.  No shares of Common  Stock or  Preferred  Stock are  subject  to
preemptive  rights or any  other  similar  rights  or any liens or  encumbrances
created or agreed to by the  Company.  As of the date  hereof,  (i) there are no
outstanding  options,   warrants,  scrip,  rights  to  subscribe  to,  calls  or
commitments  issued by the Company of any character  whatsoever  relating to, or
securities  or rights  convertible  into,  any  shares of  capital  stock of the
Company  or  its  subsidiary,  or  contracts,  commitments,   understandings  or
arrangements  by which the Company or its  subsidiary  is or may become bound to
issue additional  shares of capital stock of the Company or its subsidiary or to
issue options,  warrants, scrip, rights to subscribe to, calls or commitments of
any character  whatsoever relating to, or securities or rights convertible into,
any shares of capital stock of the Company or its subsidiary,  (ii) there are no
outstanding debt securities,  notes,  credit  agreements,  or other  agreements,
documents or instruments evidencing indebtedness for borrowed money in excess of
$250,000 of the Company or its  subsidiary or by which the Company or subsidiary
is or may become bound and (iii) there are no agreements or  arrangements  under
which the Company or its  subsidiary is obligated to register the sale of any of
their securities under the 1933 Act (except the Registration  Rights  Agreement)
or which conflict in any way with the Registration  Rights Agreement.  There are
no securities or instruments containing anti-dilution or similar provisions that
will be triggered by the issuance of any of the  Securities as described in this
Agreement. The Company has furnished to the Buyer true and correct copies of the
Company's Certificate of Incorporation,  as amended and as in effect on the date
hereof (the "Certificate of  Incorporation"),  and the Company's By-laws,  as in
effect on the date  hereof  (the  "By-laws"),  and the  terms of all  securities
convertible  into or exercisable for Common Stock and the material rights of the
holders thereof in respect thereto.

                           d. Issuance of  Securities.  The  Securities are duly
authorized  and,  upon  issuance  in  accordance  with the terms  hereof and the
Warrants,  as the  case  may  be,  shall  be  validly  issued,  fully  paid  and
non-assessable, free from all taxes, liens and charges with respect to the issue
thereof,  and are not and shall not be (except to  Buyers),  as the case may be,
subject to preemptive  rights or other  similar  rights of  stockholders  of the
Company.  The maximum number of shares of Common Stock issuable pursuant to this
Agreement,  including  those issuable upon exercise of the Warrants as currently
in effect, have been duly authorized and reserved for issuance.

                           e.  No  Conflicts.   The   execution,   delivery  and
performance of the Closing  Agreements by the Company,  and the  consummation by
the Company of the  transactions  contemplated  hereby and  thereby  (including,
without  limitation,  the  issuance  of the  Securities)  do not (i) result in a
violation  of the  Certificate  of  Incorporation  or By-laws or (ii) violate or
conflict  with,  or result  in a breach of any  provision  of, or  constitute  a
default (or an event  which with notice or lapse of time or both would  become a
default)  under,  or  give to  others  any  rights  of  termination,  amendment,
acceleration or cancellation of, any material agreement, indenture or instrument
to which the Company or its  subsidiary is a party,  or result in a violation of
any law, rule,  regulation,  order,  judgment or decree  (including  federal and
state  securities  laws and  regulations  and the rules and  regulations  of the
principal  market or exchange on which the


                                      -7-
<PAGE>

Common Stock is traded or listed) of any governmental  entity  applicable to the
Company or its  subsidiary  or by which any  property or asset of the Company or
its  subsidiary  is bound or named as a party,  the  violation  of, breach of or
conflict  with which  reasonably  could be expected  to have a Material  Adverse
Effect. Neither the Company nor its subsidiary is in violation of any term of or
in  default  under  its   Certificate  of   Incorporation   or  By-laws  or  its
organizational charter or by-laws, respectively, or in material violation of any
term  of or  in  default  under  any  material  contract,  agreement,  mortgage,
indebtedness,  indenture,  instrument, judgment, decree or order or any statute,
rule or regulation applicable to the Company or its subsidiary.  The business of
the Company and its  subsidiary is not being  conducted in violation of any law,
ordinance or regulation of any governmental  entity,  which violation reasonably
could be  expected to have a Material  Adverse  Effect.  Except as  specifically
described  in the  Closing  Agreements  and as  required  under the 1933 Act and
applicable  State  securities  laws,  the Company is not  required to obtain any
consent, authorization or order of, or make any filing or registration with, any
court or  governmental  agency or NASDAQ in order for it to execute,  deliver or
perform any of its obligations under any of the Closing Agreements in accordance
with the terms hereof or thereof. All consents, authorizations,  orders, filings
and  registrations  that the  Company  is  required  to obtain  pursuant  to the
preceding  sentence  have  been  obtained  or  effected  on or prior to the date
hereof.  Upon  consummation of the Initial  Closing,  the Company will not be in
violation of the listing requirements of the NASDAQ National Market and does not
reasonably  anticipate  that the  Common  Stock will be  delisted  by the NASDAQ
National  Market in the foreseeable  future.  The Company and its subsidiary are
unaware  of any  facts or  circumstances  which  might  give  rise to any of the
foregoing.

                           f. SEC  Documents;  Financial  Statements.  Since the
Company's initial public offering, the Company has filed all reports, schedules,
forms,  statements and other  documents  required to be filed by it with the SEC
pursuant to the reporting  requirements of the Securities  Exchange Act of 1934,
as amended (the "1934 Act") (all of the foregoing filed prior to the date hereof
and all exhibits included therein and financial statements and schedules thereto
and documents incorporated by reference therein being hereinafter referred to as
the "SEC  Documents").  The Company (i) has delivered or made  available to each
Buyer or its  representative  true and complete  copies of the SEC  Documents as
each Buyer or its  representative has requested from the Company and (ii) agrees
to  deliver  or make  available  to each  Buyer or its  representative  true and
complete  copies of any  additional  SEC  Documents,  upon request.  As of their
respective  dates, the SEC Documents  complied in all material respects with the
requirements  of the  1934  Act  and  the  rules  and  regulations  of  the  SEC
promulgated  thereunder  applicable  to the SEC  Documents,  and none of the SEC
Documents,  at the time they  were  filed  with the SEC,  contained  any  untrue
statement of a material  fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the  circumstances  under  which they were  made,  not  misleading.  As of their
respective  dates,  the financial  statements of the Company included in the SEC
Documents  complied  as  to  form  in  all  material  respects  with  applicable
accounting  requirements and the published rules and regulations of the SEC with
respect thereto. Such financial statements have been prepared in accordance with
generally  accepted  accounting  principles,  consistently  applied  during  the
periods  involved  (except (i) as may be otherwise  indicated in such  financial
statements  or the  notes  thereto,  or (ii) in the  case of  unaudited  interim
statements,  to the extent they may exclude


                                      -8-
<PAGE>

footnotes or may be condensed or summary  statements)  and fairly present in all
material respects the financial  position of the Company as of the dates thereof
and the  results of its  operations  and cash flows for the  periods  then ended
(subject,  in the  case  of  unaudited  statements,  to  normal  year-end  audit
adjustments).  No other  information  provided by or on behalf of the Company to
any  Buyer  which  is not  included  in the SEC  Documents,  including,  without
limitation,  information referred to in Section 3(d) of this Agreement, contains
any untrue  statement  of a material  fact or omits to state any  material  fact
necessary  in  order  to  make  the  statements  therein,  in the  light  of the
circumstances under which they are or were made, not misleading.

                           g.  Absence of Certain  Changes.  Except as expressly
disclosed in SEC Documents  filed after  December 31, 1998 and prior to the date
hereof,  since December 31, 1998,  there has been no material adverse change and
no  material  adverse  development  in  the  business,  properties,  operations,
condition  (financial or otherwise) or results of operations or prospects of the
Company and its subsidiary taken as a whole, it being agreed that if the Company
has sales of at least  $2.5  million  and an  operating  loss not  exceeding  $2
million  for its second  1999  fiscal  quarter,  such level of sales as net loss
shall not be deemed to constitute a material adverse change. The Company has not
taken  any  steps,  and does not  currently  expect to take any  steps,  to seek
protection pursuant to any bankruptcy law nor does the Company or its subsidiary
have any  knowledge or reason to believe that its  creditors  intend to initiate
involuntary bankruptcy proceedings.

                           h. Absence of Litigation.  There is no action,  suit,
proceeding,  inquiry or investigation before or by any court,  government agency
or  body  pending  or,  to the  knowledge  of  the  Company  or its  subsidiary,
threatened  against  or  affecting  the  Company  or  its  subsidiary  or  their
respective  directors or officers,  or the Common Stock,  wherein an unfavorable
decision, ruling or finding, individually or in the aggregate,  reasonably could
be expected to have a Material Adverse Effect.  The Disclosure Letter contains a
complete list and summary description of any pending, or to the knowledge of the
Company,   threatened  proceeding  against  or  affecting  the  Company  or  its
subsidiary, without regard to whether it could have a Material Adverse Effect.

                           i.  Acknowledgment  Regarding Buyers' Purchase of the
Securities.  The  Company  acknowledges  and  agrees  that each of the Buyers is
acting  solely in the  capacity of arm's length  purchaser  with respect to this
Agreement  and  the  transactions   contemplated  hereby.  The  Company  further
acknowledges  that each Buyer is not acting as a financial  advisor or fiduciary
of the Company (or in any similar  capacity)  with respect to this Agreement and
the transactions  contemplated  hereby and any advice given by any of the Buyers
or any of their  respective  representatives  or agents in connection  with this
Agreement and the transactions  contemplated hereby is merely incidental to such
Buyer's purchase of the Securities. The Company further represents to each Buyer
that the Company's  decision to enter into this  Agreement has been based solely
on the independent evaluation by the Company and its representatives.

                           j. No General Solicitation.  Neither the Company, nor
any person acting on its behalf, has engaged in any form of general solicitation
or general  advertising  (within


                                      -9-
<PAGE>

the meaning of Regulation D under the 1933 Act) in connection  with the offer or
sale of any of the Securities offered hereby.

                           k. No Integrated  Offering.  Neither the Company, nor
any person acting on its behalf has, directly or indirectly,  made any offers or
sales of any  security  or  solicited  any  offers  to buy any  security,  under
circumstances that would require registration of any of the Securities under the
1933 Act or cause the offering of any of the  Securities to be  integrated  with
prior  offerings by the Company for  purposes of the 1933 Act or any  applicable
stockholder approval provisions,  including, without limitation, under the rules
and  regulations  of the National  Association of Securities  Dealers  Automated
Quotation system ("NASDAQ").

                           l. Employment Matters; ERISA Matters. The Company and
its subsidiary are in compliance with all federal, state, local and foreign laws
and  regulations  respecting  employment  and  employment  practices,  terms and
conditions  of  employment  and wages and hours  except  where  failure to be in
compliance would not have a Material Adverse Effect. To the Company's knowledge,
there are no pending  investigations  involving the Company or its subsidiary by
the U.S.  Department of Labor or any other  governmental  agency responsible for
the enforcement of such federal,  state,  local or foreign laws and regulations.
To the  Company's  knowledge,  there  is no  unfair  labor  practice  charge  or
complaint  against the Company or its  subsidiary  pending  before the  National
Labor Relations Board or any strike,  picketing,  boycott,  dispute, slowdown or
stoppage  pending  or  threatened  against  the  Company or its  subsidiary.  No
collective  bargaining  agreement or  modification  thereof is  currently  being
negotiated  by the  Company  or its  subsidiary.  No  grievance  or  arbitration
proceeding  is pending  under any  expired  or  existing  collective  bargaining
agreements of the Company or its subsidiary.  No material labor dispute with the
employees of the Company or its  subsidiary  exists or, to the  knowledge of the
Company, is imminent.

                           m. Intellectual  Property Rights. The Company and its
subsidiary  own  or  possess  the  requisite  rights  or  licenses  to  use  all
trademarks,  trade names,  service marks,  service mark  registrations,  service
names, patents,  patent rights,  copyrights,  inventions,  licenses,  approvals,
governmental  authorizations,  trade  secrets  and  rights  currently  used  and
necessary to conduct their respective  businesses  (collectively,  "Intellectual
Property   Rights").   None  of  the  Intellectual   Property  Rights  or  other
intellectual  property  rights are  expected to expire or  terminate in the near
future to the extent such expiration or termination could reasonably be expected
to have a Material  Adverse  Effect.  The Company does not have any knowledge of
any event, fact or circumstance  relating to (i) any infringement by the Company
or its subsidiary of any trademarks,  trade names,  service marks,  service mark
registrations,  service names, patents, patent rights,  copyrights,  inventions,
licenses, approvals, governmental authorizations, trade secrets or other similar
rights of others,  or (ii) any person or entity now infringing any  Intellectual
Property  Rights or other  similar  rights  owned or used by the  Company or its
subsidiary  and,  to the  Company's  knowledge,  there is no  claim,  action  or
proceeding  being made or brought  against,  or being  threatened  against,  the
Company or its subsidiary regarding any trademarks,  trade names, service marks,
service mark registrations,  service names, patents, patent rights,  copyrights,
inventions, licenses, approvals,  governmental authorizations,  trade secrets or
other  similar  rights of others,  or any person or entity  now  infringing  any
Intellectual  Property


                                      -10-
<PAGE>

Rights or other similar  rights;  and the Company and its subsidiary are unaware
of any facts or circumstances which could reasonably be expected to give rise to
any of the  foregoing.  The Company  and its  subsidiary  have taken  reasonable
security  measures to protect the secrecy,  confidentiality  and value of all of
their Intellectual Property Rights.

                           n.  Environmental  Laws.  (i)  The  Company  and  its
subsidiary (A) are in material  compliance with any and all Environmental  Laws,
(B) have received all material permits,  licenses or other approvals required of
them under applicable Environmental Laws to conduct their respective businesses,
and (C) are in material  compliance  with all terms and  conditions  of any such
permit,  license or approval.  With respect to the Company and/or its subsidiary
(A) there are no past or present  releases of any material into the environment,
actions,   activities,   circumstances,   conditions,   events,   incidents,  or
contractual  obligations  attributable to such entity which may give rise to any
common law environmental  liability or any liability under any Environmental Law
by such entity and (B) neither the Company nor its  subsidiary  has received any
currently  effective  notice with  respect to the  foregoing,  nor is any action
pending  or to the  Company's  knowledge,  threatened  in  connection  with  the
foregoing.  The term  "Environmental  Laws" means all federal,  state,  local or
foreign  laws  relating  to  pollution  or  protection  of human  health  or the
environment  (including,   without  limitation,   ambient  air,  surface  water,
groundwater,  land surface or subsurface strata), including, without limitation,
laws  relating to  emissions,  discharges,  releases or  threatened  releases of
chemicals, pollutants,  contaminants, or toxic or hazardous substances or wastes
(collectively,   "Hazardous  Materials")  into  the  environment,  or  otherwise
relating to the manufacture,  processing, distribution, use, treatment, storage,
disposal,  transport  or  handling  of  Hazardous  Materials,  as  well  as  all
authorizations,   codes,  decrees,  demands  or  demand  letters,   injunctions,
judgments,  licenses,  notices  or notice  letters,  orders,  permits,  plans or
regulations issued, entered, promulgated or approved thereunder.

                                    (ii)  Other  than  those  that  are or  were
stored,  used or  disposed of in  compliance  with  applicable  law or those not
attributable  to the acts or  omissions  of the  Company or its  subsidiary,  no
Hazardous Materials are contained on or about any real property currently owned,
leased or used by the Company or its subsidiary, and no Hazardous Materials were
released on or about any real property  previously owned,  leased or used by the
Company or its  subsidiary  during the period the property was owned,  leased or
used by the Company or its subsidiary.

                                    (iii) There are no underground storage tanks
on or under  any real  property  owned,  leased  or used by the  Company  or its
subsidiary that are not in compliance with applicable Environmental Laws.

                           o. Title.  The Company and its  subsidiary  have good
and marketable  title in fee simple to all real property and good and marketable
title to all personal property owned by them that is material to the business of
the  Company  and its  subsidiary,  in each case  free and  clear of all  liens,
encumbrances  and defects except such as do not  materially  affect the value of
such property and do not materially  interfere with the use made and proposed to
be made of such  property by the Company and its  subsidiary.  Any real property
and  facilities  held


                                      -11-
<PAGE>

under  lease by the  Company and its  subsidiary  are held by them under  valid,
subsisting and  enforceable  leases with such exceptions as are not material and
do not  materially  interfere  with the use made and proposed to be made of such
property and buildings by the Company and its subsidiary.

                           p.  Insurance.  The  Company and its  subsidiary  are
insured by insurers of recognized financial  responsibility  against such losses
and risks and in such amounts as is prudent and  customary in the  businesses in
which the Company and its subsidiary  are engaged.  Neither the Company nor such
subsidiary  has any  reason  to  believe  that it will not be able to renew  its
existing  insurance  coverage  as and when such  coverage  expires  or to obtain
similar  coverage  from  similar  insurers as may be  necessary  to continue its
business  at a cost  that  would not  individually  or in the  aggregate  have a
Material Adverse Effect.

                           q. Regulatory  Permits;  Compliance.  The Company and
its subsidiary possess all franchises, grants, authorizations, licenses permits,
easements, consents, certificates,  approvals and orders necessary to own, lease
and  operate  its  properties  and to conduct  their  respective  businesses  as
currently being conducted  (collectively,  the "Company  Permits").  There is no
action  pending,  or to the knowledge of the Company,  threatened  regarding the
suspension or  cancellation of any of the Company  Permits.  Neither the Company
nor its  subsidiary  is in default or violation  of any of the Company  Permits.
Neither the Company nor its  subsidiary  has  received any  currently  effective
notification  with  respect to its possible  default or violation of  applicable
laws.

                           r. Internal Accounting Controls.  The Company and its
subsidiary maintain a system of internal accounting controls sufficient,  in the
judgment of the Company's board of directors,  to provide  reasonable  assurance
that (i)  transactions are executed in accordance with  management's  general or
specific  authorizations,  (ii) transactions are recorded as necessary to permit
preparation  of financial  statements  in  conformity  with  generally  accepted
accounting  principles  and to maintain  asset  accountability,  (iii) access to
assets is permitted  only in accordance  with  management's  general or specific
authorization and (iv) the recorded  accountability  for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

                           s. No Materially Adverse Contracts,  Etc. Neither the
Company nor its  subsidiary is subject to any charter,  corporate or other legal
restriction,  or any judgment, decree, order, rule or regulation of any court or
governmental  agency which in the reasonable  judgment of the Company's officers
has or is  expected in the future  individually  or in the  aggregate  to have a
Material  Adverse  Effect.  Neither the Company nor its subsidiary is a party to
any  contract or agreement  which in the  reasonable  judgment of the  Company's
officers has or is expected to have a Material Adverse Effect.

                           t. Tax Status. Each of the Company and its subsidiary
has made or filed  all  federal,  state  and  foreign  income  and all other tax
returns,  reports and  declarations  required by any jurisdiction to which it is
subject  (unless and only to the extent that the Company and its  subsidiary has
set aside on its books  provisions  reasonably  adequate  for the payment of


                                      -12-
<PAGE>

all unpaid and unreported  taxes) and has paid all taxes and other  governmental
assessments  and charges that are material in amount,  shown or determined to be
due on such returns,  reports and declarations,  except those being contested in
good faith and has set aside on its books provision  reasonably adequate for the
payment  of all  taxes for  periods  subsequent  to the  periods  to which  such
returns,  reports  or  declarations  apply.  There  are no  unpaid  taxes in any
material amount claimed to be due by the taxing  authority of any  jurisdiction,
and the officers of the Company know of no basis for any such claim. The Company
has not executed a waiver with respect to the statute of limitations relating to
the  assessment or collection of any foreign,  federal,  state or local tax. The
Company has not been  notified  that any of its tax returns is  currently  being
audited by any taxing authority.

                           u.  Certain  Transactions.  Except  for arm's  length
transactions pursuant to which the Company makes payments in the ordinary course
of business  upon terms no less  favorable  than the Company  could  obtain from
third parties and other than the grant of stock  options,  none of the officers,
directors or  employees  of the Company is presently a party to any  transaction
with the Company (other than for services as employees, officers and directors),
including  any  contract,  agreement  or  other  arrangement  providing  for the
furnishing  of  services  to or by,  providing  for  rental of real or  personal
property to or from,  or  otherwise  requiring  payments to or from any officer,
director or such employee or, to the knowledge of the Company,  any corporation,
partnership,  trust or other entity in which any  officer,  director or any such
employee  has a  substantial  interest  or is an officer,  director,  trustee or
partner.

                           v.  S-3   Registration.   The  Company  is  currently
eligible to register  securities,  including  the resale of the Common Stock and
the Warrant Shares, on a registration statement on Form S-3 under the 1933 Act.

                           w.  Disclosure.   All  information   relating  to  or
concerning  the  Company  or its  subsidiary  set  forth in this  Agreement  and
provided  to the  Buyers  pursuant  to Section  3(d)  hereof  and  otherwise  in
connection with the transactions  contemplated hereby is true and correct in all
material  respects  and the Company has not omitted to state any  material  fact
necessary in order to make the  statements  made herein or therein,  in light of
the  circumstances  under  which they were  made,  not  misleading.  No event or
circumstance  has occurred or information  exists with respect to the Company or
its  subsidiary or its or their  business,  properties,  operations or financial
conditions, which, under applicable law, rule or regulation of the SEC, requires
public  disclosure  or  announcement  by the  Company  but which has not been so
publicly announced or disclosed.

                           x. No Qualified Opinion. The Company has not received
an  opinion,  report or  letter  from its  auditors  qualified  in any  respect,
including  as to  the  Company's  ability  to  proceed  as a  going  concern  in
connection  with the  Company's  financial  statements  and,  provided  that the
transactions contemplated hereby are consummated, does not anticipate or know of
any basis  upon  which its  auditors  might  issue any such  opinion,  report or
letter.

                           y. Investment  Company Status. The Company is not and
upon  consummation  of the sale of the  Securities  (but  without  regard to the
status of the Buyers under


                                      -13-
<PAGE>

the  Investment  Company  Act of 1940,  as amended)  will not be an  "investment
company,"  as such term is defined in the  Investment  Company  Act of 1940,  as
amended.

                           z.  Foreign  Corrupt  Practices.   To  the  Company's
knowledge,  neither the Company nor its subsidiary,  nor any director,  officer,
agent,  employee  or  other  person  acting  on  behalf  of the  Company  or its
subsidiary  has, in the course of his actions for, or on behalf of, the Company:
(i) used any corporate funds for any unlawful contribution,  gift, entertainment
or other unlawful expenses relating to political activity;  (ii) made any direct
or indirect unlawful payment to any foreign or domestic  government  official or
employee  from  corporate  funds;  (iii)  violated  or is in  violation  of  any
provision of the U.S.  Foreign  Corrupt  Practices Act of 1977; or (iv) made any
bribe, rebate, payoff, influence payment,  kickback or other unlawful payment to
any foreign or domestic government official or employee.

                           aa. Year 2000. Any  reprogramming  required to permit
the proper functioning, in and following the year 2000, of the Company's and its
subsidiary's  (i)  computer  systems  and  (ii)  equipment  containing  imbedded
microchips (including systems and equipment supplied by others to the Company or
with  which  are  sold as an  integral  part of  Company's  or its  subsidiary's
systems) and the testing of such systems and equipment,  as so reprogrammed  has
been completed. The cost to the Company and its subsidiary of such reprogramming
and testing and of the reasonably  foreseeable  consequences of year 2000 to the
Company  and its  subsidiary  with  respect to the  matters  referred  to in the
previous sentence  (including without limitation,  reprogramming  errors and the
failure of systems or  equipment  supplied by others to the Company or which are
sold as an integral part of the Company's or its subsidiary's  systems) will not
have a Material Adverse Effect. The computer and management  information systems
of the Company and its  subsidiary are and, with ordinary  course  upgrading and
maintenance,  will  continue  to be,  sufficient  to permit the  Company and its
subsidiary  to conduct its business  without a Material  Adverse  Effect  caused
thereby.

                  5.       COVENANTS AND AGREEMENTS.

                           a.  Best  Efforts.  Each  party  shall  use its  best
efforts  timely to  satisfy  each of the  conditions  to be  satisfied  by it as

determine is necessary to qualify the  Securities  for, or obtain  exemption for
the  Securities  for,  sale to the  Buyers  at  such  Closing  pursuant  to this
Agreement  under  applicable  securities or "Blue Sky" laws of the states of the
United  States,  and shall  provide  evidence of any such action so taken to the
Buyers on or prior to such Closing Date.

                           c. Reporting Status.  Until six months after the date
as of which the  Investors (as that term is defined in the  Registration  Rights
Agreement)  may  sell  all  of the  Common  Stock  and  Warrant  Shares  without
restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor
thereto)  (the  "Registration  Period"),  the Company (x) shall  timely file all
reports  required  to be filed with the SEC  pursuant  to the 1934 Act,  and the


                                      -14-

Company  shall not  terminate  its status as an issuer  required to file reports
under the 1934 Act even if the 1934 Act or the rules and regulations  thereunder
would  otherwise  permit such  termination and (y) will use its best efforts and
take all necessary  action to maintain its ability and  eligibility  to register
securities on Form S-3.

                           d. Use of Proceeds. The Company will use the proceeds
from the sale of the Common Stock and  Warrants for working  capital and general
corporate  purposes and shall not otherwise,  directly or  indirectly,  use such

enterprise  or other person  (except in  connection  with its direct or indirect
subsidiaries)  or for the repurchase,  redemption,  or retirement of any capital
stock of the Company.

                           e. Financial Information.  The Company agrees to file
all reports,  schedules,  forms,  statements and other documents  required to be
filed by it with the SEC pursuant to the reporting requirements of the 1934 Act.
The  financial  statements  of the Company will be prepared in  accordance  with
generally accepted accounting principles,  consistently applied, and will fairly
present in all material  respects  the  consolidated  financial  position of the
Company and its  consolidated  subsidiaries  and results of their operations and
cash  flows  for the  periods  then  ended  (subject,  in the case of  unaudited
statements, to normal year-end audit adjustments).

                           f. Reservation of Shares.  The Company shall take all
action necessary to at all times have  authorized,  and reserved for the purpose
of  issuance,  no less than the number of shares of Common  Stock  necessary  to
provide for the issuance of the Warrant Shares upon exercise of the Warrants, in
accordance with the terms of this Agreement and the Warrants.

                           g.  Listing.  The Company shall  promptly  secure the
listing of the Common Stock and Warrant Shares upon the NASDAQ  National  Market
(subject to official  notice of  issuance)  and shall  maintain,  so long as any
other shares of Common Stock shall be so listed, the listing of the Common Stock
issued and all Warrant Shares from time to time issuable under the terms of this
Agreement  and the Warrants on each national  securities  exchange and automated
quotation system, if any, upon which shares of Common Stock are then listed. The
Company shall  promptly  provide to Hilal copies of any notices it receives from
NASDAQ  regarding the continued  eligibility  of the Common Stock for listing on
NASDAQ or other principal exchange or quotation system on which the Common Stock
is listed or traded.

                           h. Expenses. Each of the Company and the Buyers shall
each pay its respective costs and expenses  incurred by such party in connection
with  the  negotiation,  investigation,  preparation,  execution,  delivery  and
performance  of the Closing  Agreements;  provided,  that at the Closings (or if
sooner upon the deposits  into escrow  contemplated  by Sections 1(b) and 2(b)),
the Company shall reimburse the Buyers for Buyers'  attorneys' fees and expenses
incurred in connection with the  preparation of the Closing  Agreements up to an
aggregate of $25,000.

                           i. Additional Issuances of Securities.

                                    (i)  Right of  Purchase.  If at any time the
Company  shall  desire to issue any Common  Stock or any  security  convertible,
exchangeable  or exercisable  for Common Stock or any other right to acquire any
Common Stock (the "Convertible Securities") pursuant to Section 4(2) of the 1933
Act or an offering under  Regulation D or Regulation S of the 1933 Act or in any
other private  placement  (other than Exempt  Issuances  under  Section  5(i)(v)
below), then the Company shall comply with the terms of this Section 5(i).

                                    (ii) Notice Requirements.  The Company shall
notify,  or cause to be notified,  the Buyers not less than twenty (20) business
days prior to the time the Company  intends to  consummate  such  issuance  (the
"Issuance Notice"). The Issuance Notice shall set forth all of the terms of such
proposed issuance.

                                    (iii)  Exercise  of Right of  Purchase.  The
right of purchase  provided  for in this  Section  5(i) may be  exercised by the
Buyers by delivery of a written notice to the Company (the  "Exercise  Notice"),
within ten (10)  business  days  following  receipt of the Issuance  Notice (the
"Exercise  Period").  The Exercise Notice shall state that the Buyers (and among
them in such proportion as they may agree) desire to purchase up to that portion
of the  proposed  issuance of such Common  Stock or  Convertible  Securities  as
necessary to maintain the Buyers' pro rata ownership of the  outstanding  Common
Stock of the Company  (assuming  conversion of the  Convertible  Securities,  if
applicable) on terms  substantially equal to the terms set forth in the Issuance
Notice,  which  Exercise  Notice  shall set forth the portion of the issuance so
elected to be purchased.

                                    (iv) Right to Issue Securities. In the event
that the proposed  issuance is consummated on terms  substantially  equal to the
terms set forth in the Issuance  Notice  within  forty-five  (45)  calendar days
following the  termination of the Exercise  Period the Company shall sell to the
Buyers  concurrently the securities they elected to purchase if such issuance is
not consummated  within such 45 day period  substantially on the terms described
in the Issuance Notice, no such issuance may be made without again giving notice
to the Buyers and complying with all of the requirements of this Section 5(i).

                                    (iv)   Exempt   Issuances.   The   following
issuances of Common Stock or Convertible  Securities shall be "Exempt Issuances"
not subject to the right of purchase in this Section 5(i):

                                    (a) any shares of the Company's Common Stock
         and/or Convertible Securities issued to employees, officers, directors,
         contractors,  advisors  or  consultants  of  the  Company  pursuant  to
         incentive agreements or plans approved by the Board of Directors of the
         Company;

                                    (b) any securities issuable upon exercise of
         any Convertible Securities outstanding on the date of this agreement;


                                      -16-
<PAGE>

                                    (c)  shares of the  Company's  Common  Stock
         issued in connection with any stock split or stock dividend;

                                    (d) securities offered by the Company to the
         public pursuant to a registration  statement filed under the Securities
         Act;

                                    (e) any shares of the Company's Common Stock
         (and/or  options or  warrants  therefor)  issued or issuable to parties
         providing the Company with  equipment  leases,  real  property  leases,
         loans, credit lines, guaranties of indebtedness,  cash price reductions
         or similar financing;

                                    (f)  securities   issued   pursuant  to  the
         acquisition  of  another  corporation  or  entity  by  the  Company  by
         consolidation,  merger,  purchase  of all or  substantially  all of the
         assets, or other  reorganization  in which the Company  acquires,  in a
         single   transaction  or  series  of  related   transactions,   all  or
         substantially  all of the assets of such other corporation or entity or
         fifty  percent  (50%)  or  more of the  voting  power  of such  other c
         corporation  or entity  or fifty  percent  (50%) or more of the  equity
         ownership of such other entity; or

                                    (g)   securities   issued  to  a   strategic
         business partner who is either a supplier or customer of the Company.


                           j. Board Representation. The Company shall cause Paul
Hilal to be elected to serve on the Board of  Directors  of the Company  (or, if
Paul Hilal is unable to serve,  such other person as may be  designated by Hilal
who is  reasonably  acceptable  to the  Company)  for so long as the  Buyers  in
aggregate  hold at least 25%  (assuming  the  exercise of all  Warrants)  of all
Common Stock issued or issuable to the Buyers pursuant to this Agreement and the
Warrants.  The Company shall compensate Paul Hilal (or such other designees) for
reasonable travel expenses in connection with his duties as a Director,  and pay
such person such other  compensation as may be paid to any outside  Director not
represented  by a  venture  capital  investor  in such  person's  capacity  as a
Director.  The  Company  also  agrees  that  such  person  shall be  covered  by
director/officer  liability  insurance and indemnification by the Company to the
same extent as any other Director.

                           k. No  Integration.  The Company will not conduct any
future  offering that will be integrated with the issuance of the Securities for
purposes of the rules promulgated by the SEC.

                           l.   Confidentiality.   The  Buyers   agree  to  keep
confidential  any  non-public  information  heretofore  disclosed to them by the
Company, in accordance with customary confidentiality restrictions.

                  6.       TRANSFER AGENT INSTRUCTIONS.


                                      -17-
<PAGE>

                  The  Company  shall  issue  irrevocable  instructions  to  its
transfer agent (in the form attached hereto as Exhibit E) to issue certificates,
or at a Buyer's request, to electronically issue such shares (e.g., through DWAC
or DTC), registered in the name of each Buyer or its respective nominee(s),  for
the Warrant  Shares in such amounts as specified from time to time by each Buyer
to the Company in accordance with the terms of and upon exercise of the Warrants
(the "Irrevocable  Transfer Agent  Instructions").  Prior to registration of the
Common Stock and the Warrant Shares under the 1933 Act, such certificates  shall
bear the restrictive  legend  specified in Section 3(g) of this  Agreement.  The
Company  warrants that no instruction  with respect to the Securities other than
(i) the Irrevocable  Transfer Agent Instructions  referred to in this Section 6,
and (ii) stop  transfer  instructions  (a) to give effect to Section 3(f) hereof
(in the case of the Common Stock and the Warrant  Shares,  prior to registration
of the Common Stock and the Warrant  Shares  under the 1933 Act),  (b) to comply
with  any  SEC  or  court  order,  or  (c) to  suspend  use of a then  effective
registration  statement  in the event an  amendment  or  supplement  thereto  is
necessary,  will be given by the  Company  to its  transfer  agent  and that the
Securities  shall  otherwise be freely  transferable on the books and records of
the Company as and to the extent provided in the Closing Agreements.  Nothing in
this Section 6 shall affect in any way each Buyer's obligations and agreement to
comply with all applicable securities laws upon resale of any of the Securities.
If a  Buyer  provides  the  Company  with  an  opinion  of  counsel,  reasonably
satisfactory in form and substance to the Company, that registration of a resale
by such Buyer of any of the  Securities is not required  under the 1933 Act, the
Company  shall  permit the  transfer,  and,  in the case of the Common  Stock or
Warrant  Shares,  promptly  instruct  its  transfer  agent to issue  one or more
certificates in such name and in such  denominations as specified by such Buyer.
The Company  acknowledges that a breach by it of its obligations  hereunder will
cause  irreparable harm to the Buyers by vitiating the intent and purpose of the
transaction contemplated hereby. Accordingly,  the Company acknowledges that the
remedy  at law for a breach  of its  obligations  under  this  Section 6 will be
inadequate  and  agrees,  in the event of a breach or  threatened  breach by the
Company of the  provisions of this Section 6, that the Buyers shall be entitled,
in addition to all other available  remedies,  to an injunction  restraining any
breach and requiring  immediate issuance and transfer,  without the necessity of
showing economic loss and without any bond or other security being required.

                  7.       CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

                  The obligation of the Company  hereunder to issue and sell the
Common  Stock and  Warrants  to each  Buyer at each  Closing  is  subject to the
satisfaction,  with respect to each Buyer,  at or before the applicable  Closing
Date, of each of the following  conditions,  provided that these  conditions are
for the  Company's  sole benefit and may be waived by the Company at any time in
its sole discretion:

                           a. Such Buyer shall have executed this  Agreement and
the Registration Rights Agreement and delivered the same to the Company.

                           b.  Such  Buyer  or  the  Escrow   Agent  shall  have
delivered to the Company the purchase price for the Common Stock being purchased
by such Buyer at such

Executive  Officer and Chief Financial  Officer of the Company,  dated as of the
Closing Date, to the foregoing effect and as to board  resolutions,  incumbency,
charter  and

reserved out of its authorized and unissued Common Stock, solely for the purpose
of effecting  the exercise of the Warrants,  an  additional  number of shares of
Common Stock  sufficient  to provide for the  issuance of the Warrant  Shares in
accordance with the terms of this Agreement and the Warrants.

                           g. The Irrevocable  Transfer Agent  Instructions,  in

violate any law,  regulation or order then in effect and applicable to Buyers or
the Company.

                           i. Paul  Hilal  shall  have been  duly  elected  as a
director of the Company.

                           j. There shall not have  occurred any mutual  adverse
change in the business condition (financial or otherwise), results of operations
or prospects of the Company since the date of this Agreement.

                  9.       INDEMNIFICATION.

                           In  consideration  of  each  Buyer's   execution  and
delivery  of this  Agreement  and  acquiring  the  Securities  hereunder  and in
addition to all of the Company's other  obligations  under this  Agreement,  the
Company shall defend,  protect,  indemnify and hold harmless each Buyer and each
other holder of Securities and all of their officers,  directors,  employees and
agents  (including,  without  limitation,  those retained in connection with the
transactions   contemplated  by  this  Agreement)   (collectively,   the  "Buyer
Indemnitees")  from and against any and all  actions,  causes of action,  suits,
claims, losses, costs, penalties, fees, liabilities and damages, and expenses in
connection  therewith  (irrespective  of whether any such Buyer  Indemnitee is a
party  to the  action  for  which  indemnification  hereunder  is  sought),  and
including  reasonable  attorneys' fees and disbursements (the "Buyer Indemnified
Liabilities"),  incurred by any Buyer Indemnitee (and shall advance the same) as
a result of, or arising  out of, or  relating  to (a) any  misrepresentation  or
breach of any  representation  or  warranty  made by the  Company in the Closing
Agreements or any other certificate,  instrument or document contemplated hereby
or thereby,  (b) any breach of any  covenant,  agreement  or  obligation  of the
Company contained in the Closing Agreements or any other certificate, instrument
or document  contemplated  hereby or


                                      -20-
<PAGE>

thereby,  or (c) the  execution,  delivery,  performance  or enforcement of this
Agreement  or any other  instrument,  document or  agreement  executed  pursuant
hereto  by any of the  Buyer  Indemnitees.  To the  extent  that  the  foregoing
undertaking  by the Company  may be  unenforceable  for any reason,  the Company
shall make the maximum  contribution to the payment and  satisfaction of each of
the Buyer  Indemnified  Liabilities  which is permissible  under applicable law.
This indemnity  will survive the Initial  Closing or Second Closing for one year
after  the  date of the  Initial  Closing  and will  not  apply  to any  grossly
negligent acts or willful misconduct of any Buyer.

                  10.      GOVERNING LAW; MISCELLANEOUS.

                           a. Governing Law. This Agreement shall be governed by
and interpreted in accordance  with the laws of the State of California  without
regard to the principles of conflict of laws.

                           b.  Counterparts.  This  Agreement may be executed in
two or more identical counterparts, all of which shall be considered one and the
same agreement and shall become effective when  counterparts have been signed by
each party and delivered to the other party.  In the event any signature page is
delivered  by  facsimile  transmission,  the party  using such means of delivery
shall cause four additional  original executed  signature pages to be physically
delivered  to the other party  within five days of the  execution  and  delivery
hereof.

                           c.  Headings.  The headings of this Agreement are for
convenience   of   reference   and  shall  not  form  part  of,  or  affect  the
interpretation of, this Agreement.

                           d.  Severability.  If any provision of this Agreement
shall be  invalid or  unenforceable  in any  jurisdiction,  such  invalidity  or
unenforceability  shall  not  affect  the  validity  or  enforceability  of  the
remainder  of  this   Agreement  in  that   jurisdiction   or  the  validity  or
enforceability of any provision of this Agreement in any other jurisdiction.

                           e.  Entire  Agreement;   Amendments.  This  Agreement
supersedes all other prior oral or written  agreements  between the Buyers,  the
Company, their affiliates and persons acting on their behalf with respect to the
matters discussed herein, and this Agreement and the documents referenced herein
contain  the entire  understanding  of the parties  with  respect to the matters
covered  herein and therein  and,  except as  specifically  set forth  herein or
therein,  neither the Company nor any Buyer makes any representation,  warranty,
covenant or  undertaking  with  respect to such  matters.  No  provision of this
Agreement may be waived or amended other than by an instrument in writing signed
by the Company and Buyers purchasing a majority of the Common Stock hereunder (a
"Majority of the Buyers").

                           f. Notices. Any notices,  consents,  waivers or other

                           g.  Successors and Assigns.  This Agreement  shall be
binding  upon and inure to the  benefit  of the  parties  and  their  respective
successors and assigns,  including any purchasers of the Securities. The Company
shall not assign this Agreement or any rights or obligations  hereunder  without
the prior written  consent of a Majority of the Buyers.  A Buyer may assign some
or all of its rights  hereunder  without the consent of the  Company,  provided,
however,  that (i) any such  assignment  shall not  release  such Buyer from its
obligations  hereunder  unless such obligations are assumed by such assignee and
the Company has consented to such assignment and  assumption,  and (ii) no Buyer
may assign its rights  hereunder  in a manner that would  cause the  offering of
Securities hereunder to be required to be registered under the 1933 Act.

                           h. No Third Party  Beneficiaries.  This  Agreement is
intended for the benefit of the parties  hereto and their  respective  permitted
successors  and  assigns,  and is not for the benefit of, nor may any  provision
hereof be enforced by, any other person.

                           i. Survival.  The  representations  and warranties of
the Company and the Buyers contained in Sections 4 and 3, respectively,  and the
agreements   and  covenants  set  forth  in  Sections  5,  6  and  10,  and  the
indemnification  provisions  set forth in Section 11, shall survive the Closing.
Each Buyer shall be responsible  only for its own  representations,  warranties,
agreements and covenants hereunder.

                           j.  Publicity.  The  Company and Hilal shall have the
right to  approve  before  issuance  any  press  releases  or any  other  public
statements  with  respect to the  transactions  contemplated  hereby;  provided,
however,  that the Company  shall be  entitled,  without  the prior  approval of
Hilal, to make any press release or other public disclosure with respect to such
transactions  as is required by applicable law and  regulations  (although Hilal
shall be consulted by the Company in  connection  with any such press release or
other public  disclosure  prior to its release and shall be provided with a copy
thereof), but only to the extent required by such law or regulation.

                           k.  Further  Assurances.  Each  party  shall  do  and
perform,  or cause to be done and  performed,  all such further acts and things,
and  shall  execute  and  deliver  all  such  other  agreements,   certificates,
instruments and documents, as the other party may reasonably request in order to
carry out the intent and  accomplish  the  purposes  of this  Agreement  and the
consummation of the transactions contemplated hereby.

                           l. Enforcement. In any litigation between the parties
with respect to or arising under the Closing  Agreements,  the prevailing  party
shall be entitled to payment of its  reasonable  costs and expenses  (including,
without limitation,  reasonable legal fees and expenses) in connection therewith
from the other party.

                           m. Equitable  Relief.  Each party  recognizes that in
the event that it fails to  perform,  observe,  or  discharge  any or all of its
obligations  under this Agreement,  any remedy at law may prove to be inadequate
relief to the other parties.  Each party therefore agrees that the other parties
shall be entitled to temporary and permanent  injunctive relief in any such case
without the necessity of proving actual damages.

                                ESCROW AGREEMENT


                  This Escrow Agreement (this "Agreement") is entered into as of
July 7, 1999 (the  "Effective  Date"),  by and  among  Worldtalk  Communications
Corporation,  a Delaware  corporation  doing  business as Worldtalk  Corporation
("Worldtalk"),   the  Investors   listed  on  Exhibit  A  attached  hereto  (the
"Investors"),   Hilal   Capital   Management   LLC,   as   representative   (the
"Representative")  of the  Investors  and State Street Bank and Trust Company of
California, N.A., as escrow agent (the "Escrow Agent").

                  A.  Worldtalk and the Investors have entered into a Securities
Purchase Agreement of even date herewith (the "Agreement") pursuant to which the
Investors  may acquire up to  3,333,334  shares of the Common Stock of Worldtalk
(the  "Common  Stock")  at a  purchase  price of $3.00 per share and  seven-year
warrants for the  purchase of up to  1,666,667  shares of such Common Stock that
are exercisable at $7.00 per share (the "Warrants").  The capitalized terms used
in this Agreement and not otherwise  defined herein will have the meanings given
them in the Agreement.

                  B. Pursuant to the  Agreement,  an aggregate of $10,000,000 in
cash (the  "Purchase  Price") is to be provided by the  Investors for payment to
Worldtalk  in return for  issuance  and sale of the  shares of Common  Stock and
Warrants, if acquired by the Investors.

                  C.  The  Agreement  provides  that  the  Purchase  Price,  the
certificates representing the Common Stock (the "Certificates") and the Warrants
be placed in an escrow account (the "Escrow Account") until  satisfaction of the
condition  to  release of the  escrow as set forth in  Section  1.2,  clause (b)
hereof no later than the close of business on July 14, 1999.

                  D. The  parties  hereto  desire  to  establish  the  terms and
conditions  pursuant  to which the  Purchase  Price,  the  Certificates  and the
Warrants  (collectively,  the "Escrow  Assets") will be deposited,  held in, and
released from the Escrow Account.

                  NOW, THEREFORE, the parties hereto hereby agree as follows:

                  1.       Deposit and Release of Escrow Assets.

                           1.1      Delivery of Escrow Assets.

                                    (a) On the  Effective  Date,  Worldtalk  has
sent the Certificates and the Warrants to Escrow Agent via overnight courier for
deposit in the Escrow  Account,  the Investors  have initiated wire transfers of
the Purchase  Price to the Escrow  Agent.  In the event any of the Escrow Assets
are not received by the Escrow  Agent on or before July 8, 1999,  it will notify
the party who sent or was to have  sent the same and that  party  will have five
days from the date of such notice to deliver  the missing  portion of the Escrow
Assets to the Escrow  Agent.  Within one day after  receipt of all of the Escrow
Assets,  the Escrow  Agent will  notify  Worldtalk  and  Representative  of such
receipt.



<PAGE>

                                    (b)  The  Escrow  Agent  shall  deposit  the
Purchase Price,  the Certificates and Warrants in an account at the Escrow Agent
(or an  affiliate  or  custodian  acting on its  behalf)  that will serve as the
Escrow  Account.  The Escrow Agent shall  invest the Purchase  Price in the SSgA
U.S.  Treasury Money Market Fund, which is a money market mutual fund registered
under the  Investment  Company Act of 1940,  the  principal of which is invested
solely in obligations issued or guaranteed by the United States Government.  All
interest or any other  income  earned with respect to such  investment  shall be
retained  by the Escrow  Agent as part of Escrow  Assets  until  distributed  in
accordance  with the  other  provisions  of this  Agreement.  For tax  reporting
purposes,  all such income  shall be  allocated to Worldtalk or otherwise as the
parties may agree in writing.

                           1.2 Release from Escrow.  The Escrow  Assets shall be
maintained  in the Escrow  Agent's  Escrow  Account until the earlier of (a) the
close of business by Escrow Agent in California on July 14, 1999, which date and
time may be extended or  otherwise  changed  upon the written  agreement  of the
Representative  and Worldtalk  received by the Escrow Agent (such date and time,
as so extended or changed,  being referred to as the "Termination Time"), or (b)
presentation by Worldtalk and the  Representative of their joint instruction for
release of the Escrow  Account  (the  "Release  Notice"),  which each such party
agrees  to  execute   promptly  upon  receipt  of  a  letter  or  other  written
notification  from The Nasdaq National  Market  ("Nasdaq")  confirming  Nasdaq's
approval of the continued listing on Nasdaq of Worldtalk's  Common Stock subject
to no conditions  other than  consummation of the Initial Closing (as defined in
the  Agreement)  and subject to Nasdaq's  published  requirements  for continued
listing, all of which shall then be satisfied.  Worldtalk and the Representative
will be required to execute and deliver the Release  Notice to the Escrow  Agent
if in their  reasonable,  good faith opinions the  requirements of the preceding
sentence  have  been  met.  Upon  receipt  of the  Release  Notice  prior to the
Termination  Time, the Escrow Agent shall forthwith,  but no later than two days
thereafter, deliver:

                  (i) the Purchase Price (less indemnities and expenses, if any,
         payable pursuant to Section 4.2) in full to Worldtalk; and

                  (ii) the  Certificates  and  Warrants to each  Investor in the
         denominations  set forth for each such  Investor  on  Exhibit A to this
         Agreement.

If the  Release  Notice  is  not  received  by the  Escrow  Agent  prior  to the
Termination  Time,  Escrow  Agent  shall  forthwith,  but no later than two days
thereafter, return:

                  (y)  to  each  Investor  the  portion  of the  Purchase  Price
         originally  deposited into the Escrow  Account by such Investor,  which
         amount is set forth for each such  Investor  on Exhibit A hereto  (less
         indemnities and expenses, if any, payable pursuant to Section 4.2); and

                  (z) to Worldtalk, the Certificates and the Warrants.

Interest on the Purchase  Price shall be paid,  when it has been received by the
Escrow Agent,  to Worldtalk or the  Investors,  as  applicable.  Any delivery to
Worldtalk  and the  Investors of any  Certificates  and Warrants will be made to
them by overnight  courier  delivery at their addresses  identified in Section 7
below for the purposes of notice,  upon which the Escrow Agent may


                                      -2-
<PAGE>
conclusively rely. Delivery of the Purchase Price to Worldtalk and the Investors
shall be made by wire transfer  initiated by Escrow Agent no later than two days
after the date required for distribution  above in accordance with wire transfer
instructions  set forth in Section 7 or Exhibit A, as the case may be. All risks
of shipment shall be borne by the intended recipient.

                          1.3  Certificates.  Certificates  representing  Common
Stock  and  Warrants  shall  be  registered  in the  names of the  Investors  in
accordance with Exhibit A attached  hereto.  If  certificates  are issuable to a
person  other  than the  Investors  in  accordance  with  Exhibit  A,  then such
certificates  shall be  accompanied  no  later  than  July  14,  1999 by a fully
executed  stock power bearing a "medallion"  signature  guarantee and the Escrow
Agent shall be deemed to have delivered such  certificates when it has delivered
the appropriate stock certificates and stock powers to the transfer agent of the
Common  Stock  (currently  Harris  Trust and Savings  Bank) and the  Warrants to
Worldtalk,  together with  instructions as to how the newly-issued  certificates
are to be issued. In each case, certificates shall be issued to the Investors at
their addresses set forth in Exhibit A.

                          1.4 No Encumbrance. No portion of the Escrow Assets or
any beneficial  interest therein may be pledged,  sold, assigned or transferred,
including  by  operation  of law, by the  Investors  or Worldtalk or be taken or
reached by any legal or equitable  process in  satisfaction of any debt or other
liability  of the  Investors  or  Worldtalk,  other  than  as  provided  in this
Agreement.

                          1.5 Tax Reporting  Matters.  Worldtalk hereby provides
the  Escrow  Agent with its tax  identification  numbers  (77-0303581)  and will
furnishing  form W-9 and other  forms and  documents  that the Escrow  Agent may
reasonably  request to the Escrow Agent within three days after the date hereof.
In the event that any  interest is to be paid to the  Investors,  each  Investor
will  provide  the  Escrow  Agent with a form W-9 prior to the  delivery  by the
Escrow Agent to the Investor of such  interest.  The parties  hereto  understand
that,  if such tax  reporting  documentation  is not so  certified to the Escrow
Agent,  the Escrow Agent may be required by the Internal Revenue Code, as it may
be amended  from time to time,  to  withhold a portion of any  interest or other
income earned on the  investment of monies or other  property held by the Escrow
Agent pursuant to this Agreement.

         2.       Representative.

                          2.1 Acceptance of  Appointment.  Each of the Investors
hereby appoints Representative as such Investor's  attorney-in-fact for purposes
of entering into any document,  amending or terminating  this Agreement,  giving
any  consent and making any waiver  under this  Agreement.  Representative  each
hereby accepts its appointment as the  Representative by the Investors,  and, in
connection  therewith,  agrees to serve as a representative of the Investors for
purposes of this Agreement and as  attorney-in-fact  and agent for and on behalf
of each Investor with respect to the subject matter hereof.

                          2.2 Change in  Representative.  The Representative may
be changed by the Investors from time to time upon not less than two days' prior
written notice to the Escrow Agent and Worldtalk; provided that a Representative
may not be removed unless Investors  contributing  more than 50% of the Purchase
Price to the Escrow  Account (a  "Majority")  agree to such  removal  and to the
identity  of  the   substituted   agent.  No  bond  shall  be  required  of  the
Representative,  and the


                                      -3-
<PAGE>

Representative shall not receive compensation for its services. The Escrow Agent
need  not  inquire  into or  verify  that a  successor  Representative  has been
appointed in accordance with the requirements of this Section 2.2.  Rather,  the
Escrow Agent may rely on  certificates  that are delivered to it by any party to
this Agreement and may assume without inquiry or notice to any other person that
any facts stated therein are correct.

                          2.3 Limitation of Liability.  The Representative shall
not be liable  for any act done or omitted  hereunder  as  Representative  while
acting in good faith and in the exercise of reasonable  judgment.  The Investors
by or on whose  behalf  the  Purchase  Price  was  contributed  shall  severally
indemnify the Representative  and hold the  Representative  harmless against any
loss, liability or expense incurred without gross negligence or bad faith on the
part  of the  Representative  and  arising  out  of or in  connection  with  the
acceptance or administration of the Representative's  duties hereunder including
the  reasonable  fees  and  expenses  of  any  legal  counsel  retained  by  the
Representative.

                  3.      Escrow Agent.

                          3.1  Duties.  The Escrow  Agent  shall only have those
duties as are expressly set forth in this Agreement, and no implied duties shall
be read into this  Agreement.  The Escrow  Agent will  incur no  liability  with
respect to any action  taken or  suffered  by it in  reliance  upon any  notice,
direction,  instruction,  consent, statement or other document believed by it to
be genuine and duly authorized, nor for any other action or inaction, except its
own  willful  misconduct  or gross  negligence.  The  Escrow  Agent  will not be
responsible for the validity or sufficiency of this Agreement.  In all questions
arising under this Agreement, the Escrow Agent may rely on the advice or opinion
of counsel,  including  in-house  counsel,  and for  anything  done,  omitted or
suffered in good faith by the Escrow Agent based on such advice or opinion,  the
Escrow Agent will not be liable to anyone. The Escrow Agent will not be required
to take any action  hereunder  involving any expense  unless the payment of such
expense is made or provided for in a manner satisfactory to it. The Escrow Agent
shall not be obligated to take any legal action or other action  hereunder which
might,  in its judgment,  involve any expense or liability  unless it shall have
been furnished with acceptable indemnification.

                          3.2  Conflicting  Demands.  In the  event  conflicting
demands are made or  conflicting  notices are served upon the Escrow  Agent with
respect to the Escrow Account, the Escrow Agent will have the absolute right, at
the Escrow Agent's election,  to do either or both of the following:  (a) resign
so a successor can be appointed  pursuant to Section 5 hereof or (b) file a suit
in  interpleader  and  obtain an order  from a court of  competent  jurisdiction
requiring  the parties to  interplead  and litigate in such court their  several
claims and rights  among  themselves.  In the event  such  interpleader  suit is
brought, the Escrow Agent will thereby be fully released and discharged from all
further obligations imposed upon it under this Agreement, and Worldtalk will pay
the Escrow  Agent  (subject  to  reimbursement  from the  Investors  pursuant to
Section 4.1 hereof) all costs,  expenses and reasonable attorney's fees expended
or  incurred by the Escrow  Agent  pursuant  to the  exercise of Escrow  Agent's
rights under this Section 3.

                          3.3  Notice.  The Escrow  Agent shall not be deemed to

for  administering  this  Agreement or unless in writing  received by the Escrow
Agent  and  making  specific  reference  to  this  Agreement.   If  any  notice,
certificate  or other  document is required to be  delivered to the Escrow Agent
and any other person,  the Escrow Agent may assume without inquiry that any such
document  which the Escrow  Agent has  received  has also been  received by such
other person.

                          3.4  Ambiguity  or  Uncertainty.  In the  event of any
ambiguity or uncertainty under this Agreement, or in any notice, instruction, or
other  communication  received by the Escrow Agent  hereunder,  the Escrow Agent
may, in its discretion,  refrain from taking action,  and may retain the pledged
collateral until and unless it receives written  instruction signed by Worldtalk
and the Representative which eliminates such uncertainty or ambiguity.

                          3.5  Survival  of  Indemnifications;   Limitations  of
Liability.  All  indemnifications  contained in the  Agreement and the following
limitations  of the Escrow Agent's  liability  shall apply and shall survive the
resignation or removal of the Escrow Agent, and shall survive the termination of
this Agreement.

                                    (a) The Escrow Agent is not  responsible for
         the recitals appearing in this Agreement.  The recitals shall be deemed
         to be statements of the other parties to this  Agreement and the Escrow
         Agent shall not be charged with knowledge of, or under any  obligations
         to  determine  or  interpret,  the meaning of any terms  defined in the
         Agreement for purposes of performing or observing its duties hereunder.

                                    (b) The Escrow  Agent has no  responsibility
         for the sufficiency of this Agreement for any purpose. Without limiting
         the  foregoing,  if any  security  interest is referred to herein,  the
         Escrow   Agent  shall  have  no   responsibility   for,  and  makes  no
         representation   or  warranty  as  to,  the  creation,   attachment  or
         perfection of any such  security  interest or the  sufficiency  of this
         Agreement.

                                    (c) Nothing in this Agreement shall obligate
         the Escrow  Agent to qualify to do business or act in any  jurisdiction
         in which it is not presently qualified to do business,  or be deemed to
         impose upon the Escrow Agent the duties of a trustee. The duties of the
         Escrow Agent under this Agreement are strictly ministerial in nature.

                                    (d) In no event shall the Escrow  Agent have
         any  liability for any failure or inability of any of the other parties
         to perform or observe its duties under the Agreement, or by reason of a
         breach of this  Agreement  by any of the other  parties  hereto.  In no
         event shall the Escrow Agent be  obligated  to take any action  against
         any of the other parties to compel performance hereunder.

                                    (e) The Escrow Agent shall in no instance be
         obligated to commence,  prosecute  or defend any legal  proceedings  in
         connection herewith. The Escrow Agent shall be authorized and entitled,
         however,  in any  instance to  commence,  prosecute or defend any legal
         proceedings in connection  herewith,  including without  limitation any
         proceeding it may deem  necessary to resolve any matter or dispute,  to
         obtain a  necessary  declaration


                                      -5-
<PAGE>

         of  rights,  or to  appoint a  successor  upon  resignation  (and after
         failure by Worldtalk to appoint a successor, as provided below).

                                    (f) The Escrow Agent shall in no instance be
         under any duty to give any property  held by it  hereunder  any greater
         degree  of care  than it gives its own  similar  property.  In no event
         shall the Escrow Agent have any obligation to advance or risk funds.

                                    (g) In no event  shall the  Escrow  Agent be
         liable for any indirect, punitive, special or consequential damages.

                                    (h) The Escrow Agent shall have no liability
         for the actions or omissions  of any  book-entry  depository,  transfer
         agent,  nominee,  correspondent,  subagent or subcustodian.  The Escrow
         Agent  shall  be  permitted  to use  the  services  of  any  recognized
         securities  depository or clearing agent, such as (without  limitation)
         The Depository  Trust Company and the Federal  Reserve Bank  book-entry
         securities system, as applicable,  in connection with any securities or
         investments held hereunder.

                                    (i)   The   Escrow   Agent   shall   not  be
         responsible or liable for delays or failures in  performance  resulting
         from acts  beyond  its  control.  Such acts  shall  include  but not be
         limited  to  acts  of  God,  strikes,  lockouts,  riots,  acts  of war,
         epidemics,  laws or  governmental  regulations  changes or superimposed
         after the fact,  fire,  communication  line failures,  power  failures,
         computer viruses,  earthquakes or other disasters, or to unavailability
         of Federal Reserve Bank wire or telex facilities.

                                    (j) The Escrow Agent's duties are limited to
         those set forth in this Agreement and applicable laws, and Escrow Agent
         is not charged with knowledge of or any duties or  responsibilities  in
         connection  with any other  document  or  agreement  including  without
         limitation the Agreement.

                  4.       Fees and Expenses and Indemnity.

                           4.1 Division of Payment. All fees and expenses of the
Escrow  Agent  incurred  in the  acceptance  of and in the  ordinary  course  of
performing  its  responsibilities   hereunder  will  be  paid  by  Worldtalk  in
accordance with the schedule of fees attached hereto as Exhibit B. Such fees and
expenses  shall be paid by  Worldtalk  to the  Escrow  Agent  upon  receipt of a
written invoice sent to Worldtalk by Escrow Agent.  Any  extraordinary  fees and
expenses shall also be paid by Worldtalk;  provided,  however,  that any fees or
expenses  incurred by the Escrow  Agent in  connection  with a dispute  over the
release  of the  Escrow  Assets,  will be paid by the  party  (Worldtalk  or the
Investors) who does not substantially  prevail in such dispute,  and if there is
no such party,  as determined by the court or by the parties in agreement,  such
fees and expenses  will be paid 50% by Worldtalk  and 50% by the  Investors  (in
proportion  as  among  themselves  to the  Purchase  Price  paid  by  each  such
Investor).  The  Investors'  liability  for the fees and  expenses of the Escrow
Agent shall be paid by Worldtalk  and  recovered  out of the Escrow Assets to be
delivered  to such  Investors.  To the extent that  insufficient  Escrow  Assets
remain to cover the Investors' liability


                                      -6-
<PAGE>

for the fees and expenses of the Escrow  Agent,  Worldtalk  shall  indemnify the
Escrow Agent for such fees and expenses.

                           4.2      Agent Indemnification.

                                    (a) Each of Worldtalk and the Investors,  as
provided in Section 4.2(b) below,  hereby  covenants and agrees to indemnify the
Escrow Agent, its directors,  officers, agents and employees, for, and to defend
and hold them harmless from and against, any and every loss, liability,  damage,
claim,  cost and expense of any nature  incurred or suffered by the Escrow Agent
and arising out of or in connection with this Agreement or the administration of
this  Agreement  or the  performance  or  observance  by the Escrow Agent of its
responsibilities or services under this Agreement  (including but not limited to
attorneys  fees and other costs and expenses of defending or preparing to defend
against  any claim or  liability),  unless and  except to the extent  such loss,
liability,  damage,  cost or expense  shall be caused by the Escrow  Agent's own
willful misconduct or gross negligence  ("Indemnifiable  Expenses").  The Escrow
Agent shall be entitled to reimbursement on demand for all expenses  incurred in
connection  with the  administration  of this  Agreement  or the escrow  created
hereby which are in excess of its  compensation  for normal services  hereunder,
including,  without limitation,  payment of any legal fees and expenses incurred
by the Escrow Agent in connection  with the resolution of any claim by any party
hereunder ("Reimbursable Expenses").

                                    (b) Worldtalk and the Investors  agree among
themselves that the Indemnifiable  Expenses and the Reimbursable Expenses of the
Escrow  Agent  will be  paid  50% by  Worldtalk  and  50% by the  Investors  (in
proportion  as  among  themselves  to the  Purchase  Price  paid  by  each  such
Investor);   provided,   however,  if  such   indemnification  or  reimbursement
obligations  arose out of a dispute  between  Worldtalk and the Investors,  such
Indemnifiable  Expenses  and  Reimbursable  Expenses  shall be paid by the party
(Worldtalk or the Investors) who does not substantially prevail in such dispute,
as determined by the court or by the parties in agreement.  The Escrow Agent may
deduct  Indemnifiable   Expenses  and  Reimbursable   Expenses,   if  any,  from
distributions that otherwise would be made pursuant to Section 1.2.

                           4.3      Tax Payments.  Worldtalk  agrees  to  assume
any and all obligations  imposed now or hereafter by any applicable tax law with
respect to the  release of Escrow  Assets  under this  Agreement,  and,  without
limiting the  generality  of Section 4.2 above,  hereby  agrees to indemnify and
hold the Escrow Agent  harmless  from and against any taxes,  additions for late
payment,  interest,  penalties and other expenses,  that may be assessed against
the Escrow Agent on any such payment or other activities under this Agreement.

                  5.  Successor  Escrow  Agent.  In the event the  Escrow  Agent
becomes  unavailable  or  unwilling to continue in its  capacity  herewith,  the
Escrow  Agent may  resign  and be  discharged  from its  duties  or  obligations
hereunder by giving notice of its  resignation to the parties to this Agreement,
specifying  a date not less than ten days'  following  such  notice date of when
such  resignation  will  take  effect.  Worldtalk  and the  Representative  will
designate  a successor  Escrow  Agent prior to the  expiration  of such  ten-day
period by giving  joint  written  notice to the  Escrow  Agent as to a  mutually
acceptable  successor  Escrow Agent.  The Escrow Agent will promptly deliver the
Escrow  Assets to such  designated  successor.  If no successor  Escrow Agent is
named by


                                      -7-
<PAGE>

Worldtalk  and the  Representative,  the  Escrow  Agent  may apply to a court of
competent jurisdiction for appointment of a successor Escrow Agent.

                  6. Disputes  Involving the Escrow Agent.  It is understood and
agreed that should any dispute  arise with respect to the  delivery,  ownership,
right of possession,  and/or  disposition  of the Escrow  Assets,  or should any
claim be made upon such Escrow  Assets by a third  party,  the Escrow Agent upon
receipt of written notice of such dispute or claim by the parties hereto or by a
third party,  is  authorized  and directed to retain in its  possession  without
liability to anyone,  all or any of said Escrow  Assets until such dispute shall
have been settled either by the mutual written agreement of the parties involved
or by a final  order,  decree  or  judgment  of court in the  United  States  of
America,  the time for perfection of an appeal of such order, decree or judgment
having expired.  The Escrow Agent may, but shall be under no duty whatsoever to,
institute or defend any legal proceedings that relate to the Escrow Assets.

                  7. Notices. Any notice, certificate, consent, determination or
other  communication  required  or  permitted  to be  given or made  under  this
Agreement  shall be in writing  and shall be  effectively  given and made if and

                          REGISTRATION RIGHTS AGREEMENT


                  REGISTRATION RIGHTS AGREEMENT (this "Agreement"),  dated as of
July 7, 1999,  by and among  Worldtalk  Communications  Corporation,  a Delaware
corporation, with headquarters located at 5155 Old Ironsides Drive, Santa Clara,
CA 95054 (the  "Company"),  and the  undersigned  buyers  (each,  a "Buyer"  and
collectively, the "Buyers").

                  WHEREAS:

                  A. In connection with the Securities Purchase Agreement by and
among  the  Company  and the  Buyers  and  dated  of  even  date  herewith  (the
"Securities  Purchase  Agreement"),  the Company has agreed,  upon the terms and
subject to the conditions of the  Securities  Purchase  Agreement,  to issue and
sell to the Buyers shares of the Company's Common Stock $.01 par value per share
(the "Common Stock");

                  B. In  consideration  for the Buyers  agreeing to purchase the
Common Stock,  the Company  shall issue and deliver to the Buyers  warrants (the
"Warrants") to purchase  additional shares of Common Stock pursuant to the terms
of Common Stock Purchase Warrants (the shares of Common Stock issued or issuable
upon  exercise of the  Warrants  are  hereinafter  referred  to as the  "Warrant
Shares"); and

                  C. To induce the Buyers to execute and deliver the  Securities
Purchase  Agreement,  the  Company  has agreed to provide  certain  registration
rights  under  the  Securities  Act of  1933,  as  amended,  and the  rules  and
regulations  thereunder,  or any similar  successor statute  (collectively,  the
"1933 Act"), and applicable state securities laws;

                  NOW,  THEREFORE,  in  consideration  of the  premises  and the
mutual covenants contained herein and other good and valuable consideration, the
receipt and  sufficiency of which are hereby  acknowledged,  the Company and the
Buyers hereby agree as follows.

         1.       DEFINITIONS.

                  As used in this Agreement,  the following terms shall have the
following meanings:

                  a.  "Investor"  means a Buyer and any  transferee  or assignee
thereof to whom a Buyer  assigns its rights under this  Agreement and who agrees
to become bound by the provisions of this  Agreement in accordance  with Section
9.

                  b. "Person" means a corporation,  a limited liability company,
an association,  a partnership,  an organization,  a business, an individual, an
entity,  a  governmental  or  political  subdivision  thereof or a  governmental
agency.

<PAGE>

                  c. "register,"  "Registered,"  and  "registration"  refer to a
registration   effected  by  preparing  and  filing  one  or  more  Registration
Statements  in  compliance  with the 1933 Act and pursuant to Rule 415 under the
1933 Act or any successor rule providing for offering securities on a continuous
basis ("Rule 415"),  and the  declaration or ordering of  effectiveness  of such
Registration   Statement(s)  by  the  United  States   Securities  and  Exchange
Commission (the "SEC").

                  d. "Registrable  Securities" means (i) the Common Stock issued
and sold pursuant to the Securities Purchase Agreement,  (ii) the Warrant Shares
issued or issuable upon exercise of the Warrants and (iii) any shares of capital
stock issued or issuable with respect to the Common Stock, Warrant Shares or the
Warrants  as a result  of any stock  split,  stock  dividend,  recapitalization,
exchange or similar event, but excluding in all cases any Registrable Securities
sold by a person in a transaction  in which rights under this  Agreement are not
assigned in accordance  herewith or any Registrable  Securities  which have been
sold to the public or sold pursuant to Rule 144 promulgated under the 1933 Act.

                  e. "Registration  Statement" means a registration statement of
the Company  filed under the 1933 Act,  subject to Section 2 hereof or any other
provision of this Agreement, as applicable.

         Capitalized  terms used herein and not otherwise  defined  herein shall
have the respective meanings set forth in the Securities Purchase Agreement.

         2.       REGISTRATION.

                  a. Mandatory Registration.  The Company shall prepare, and, on
or prior to 45 days after the later of the Closing Date or the date the Purchase
Price is released to the Company  pursuant to the Escrow Agreement (the "Release
Date"),  file with the SEC a Registration  Statement or Registration  Statements
(as is  necessary)  on Form  S-3 (or,  if such  form is  unavailable  for such a
registration,  on such  other  form as is  available  for  such a  registration,
subject to the consent of each Buyer and the  provisions of Section 2(c),  which
consent will not be  unreasonably  withheld),  covering the resale of all of the
Registrable  Securities,  which  Registration  Statement(s) shall state that, in
accordance  with Rule 416  promulgated  under the 1933  Act,  such  Registration
Statement(s)  also  covers such  indeterminate  number of  additional  shares of
Common  Stock as may become  issuable  upon  exercise of the Warrants to prevent
dilution resulting from stock splits,  stock dividends or similar  transactions.
Such  registered  shares of Common Stock shall be allocated  among the Investors
pro rata based on the total number of Registrable  Securities issued or issuable
as of each date that a  Registration  Statement,  as  amended,  relating  to the
resale of the  Registrable  Securities  is declared  effective  by the SEC.  The
Company shall use its best efforts to have the Registration  Statement  declared
effective  by the SEC by the  earlier  of 135 days  after the  Release  Date and
December 14, 1999.

                  b.  Counsel  and  Investment  Bankers.  Subject  to  Section 5
hereof,  in  connection  with any offering  pursuant to Section 2, the Investors
shall have the right to select legal counsel and an investment banker or bankers
and manager or managers to  administer  their  interest in the  offering,  which
investment  banker  or  bankers  or  manager  or  managers  shall be

                                       -2-
<PAGE>

reasonably  satisfactory to the Company.  The Company shall reasonably cooperate
with any such counsel and investment bankers.

                  c.  Eligibility  for Form  S-3.  The  Company  represents  and
warrants  that as of the date  hereof it meets the  requirements  for the use of
Form S-3 for  registration  of the sale by the Buyers and any other  Investor of
the Registrable  Securities and the Company has filed and shall file all reports
required  to be filed by the  Company  with the SEC in a timely  manner so as to
maintain such eligibility for the use of Form S-3.

                  d.   Termination   of  Rights.   The  Company  shall  have  no
obligations  pursuant to this Agreement to Register any  securities  held by any
Investor if, in the opinion of counsel to the Company, which opinion and counsel
are  reasonably  acceptable  to  the  Investor  (Fenwick  &  West  being  deemed
acceptable)  and which  opinion  is also  addressed  to the  Investor,  all such
securities  proposed to be registered or as to which registration is to continue
may be sold by an Investor in a three-month  period without  registration  under
the 1933 Act pursuant to Rule 144 thereunder.

         3.       RELATED OBLIGATIONS.

                  The  Company   will  use  its  best   efforts  to  effect  the
registration of the Registrable  Securities in accordance with the terms hereof,
including the following obligations:

                  a.  The  Company  shall  use its  best  efforts  to  keep  the
Registration Statement filed pursuant to Section 2(a) effective pursuant to Rule
415 at all times until the later of the second  anniversary  of the last Closing
under the  Securities  Purchase  Agreement  or until  such  date as the  Buyers'
accountants  confirm that a discount to market price would not be applied to the
Buyers' holdings of Common Stock for financial statement valuation purposes (the
"Registration  Period").  At least 30 days prior to the end of the  Registration
Period,  the Company and the  Investors  will  confer to  determine  whether any
Investor  continues to be an affiliate  (for purposes of the federal  securities
laws) of the Company. A notice from an Investor to the Company that the Investor
believes that it is an affiliate  shall be conclusive for purposes hereof unless
the  Company  furnishes  such  Investor  with an  opinion  on which it may rely,
reasonably  acceptable to such Investor,  of counsel reasonably accepted to such
Investor,  to the effect that it is not an affiliate,  delivers to such Investor
certificates for its Common Stock and Warrants not bearing  restrictive  legends
and terminates any stop transfer  instructions  as to such  securities  with its
transfer agent.

                  In the event that any Investor will remain an affiliate  after
the end of this  Registration  Period,  then the Company may elect either to (a)
continue to keep the Registration  Statement effective as to such Investor until
such time as such  Investor is not an  affiliate  (and the  Registration  Period
shall  be  extended   accordingly),   or  (b)  notify  such  Investor  that  the
Registration  Statement  will  not  be  kept  effective  after  the  end  of the
Registration  Period,  in which  event such  Investor,  together  with all other
Investors  who  remain  affiliates,  shall  be  entitled  to  up to  two  demand
registrations on Form S-3 (or, if the Company is not then eligible for Form S-3,
such other Form which the Company is  eligible to use) during each twelve  month
period following the end of the Registration Period, and piggyback  registration
rights. The

                                       -3-
<PAGE>

Company and such  Investor  shall  negotiate  in good faith an Amendment to this
agreement setting forth such demand and piggyback rights in customary form.

                  The  Registration  Statement(s)  (including  any amendments or
supplements  thereto and prospectuses  contained  therein) shall not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein,  or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading.

                  As  set  forth  in  the  Warrants,   in  the  event  that  the
Registration  Statement is not  declared  effective by the SEC by the earlier of
135 days after the Release Date and  December 14, 1999,  the number of shares of
Common Stock issuable pursuant to each Warrant shall increase by 10% for each 30
day period  thereafter  (pro rated for any  partial  period  thereof)  until the
Registration Statement becomes effective.

                  b.  The  Company  shall  prepare  and  file  with the SEC such
amendments  (including   post-effective   amendments)  and  supplements  to  the
Registration  Statement(s)  and the  prospectus(es)  used in connection with the
Registration Statement(s), which prospectus(es) are to be filed pursuant to Rule
424 promulgated under the 1933 Act, as may be necessary to keep the Registration
Statement(s)  effective at all times during the Registration  Period (subject to
Section 3(f) below), and, during such period,  comply with the provisions of the
1933 Act with respect to the  disposition of all  Registrable  Securities of the
Company covered by the Registration  Statement(s) until such time as all of such
Registrable  Securities  shall  have been  disposed  of in  accordance  with the
intended methods of disposition by the seller or sellers thereof as set forth in
the Registration  Statement(s) or the Registration Period terminates,  whichever
occurs first.

                  c.  The  Company  shall   furnish  to  each   Investor   whose
Registrable  Securities are included in the  Registration  Statement(s)  and its
legal counsel  without  charge (i) promptly after the same is prepared and filed
with the SEC at least one copy of the  Registration  Statement and any amendment
thereto,   including   financial   statements  and   schedules,   all  documents
incorporated therein by reference and all exhibits, the prospectus(es)  included
in such Registration  Statement(s)  (including each preliminary prospectus) and,
with regards to the Registration  Statement,  any correspondence by or on behalf
of the  Company to the SEC or the staff of the SEC and any  correspondence  from
the SEC or the staff of the SEC to the Company or its representatives, (ii) upon
the  effectiveness  of  any  Registration  Statement,  ten  (10)  copies  of the
prospectus  included  in such  Registration  Statement  and all  amendments  and
supplements  thereto  (or such  other  number  of copies  as such  Investor  may
reasonably  request) and (iii) such other  documents,  including any preliminary
prospectus,  as such Investor may reasonably  request in order to facilitate the
disposition of the Registrable  Securities  owned by such Investor.  The Company
will promptly respond to any and all comments received from the SEC, with a view
towards  causing  any  Registration  Statement  or any  amendment  thereto to be
declared  effective  by the SEC as soon as  practicable  and  shall,  subject to
Section  3(h),  promptly  file an  acceleration  request as soon as  practicable
following  the  resolution  or clearance of all SEC comments or, if  applicable,
following  notification  by the  SEC  that  the  Registration  Statement  or any
amendment thereto will not be subject to review.

                                      -4-
<PAGE>

                  d. The Company  shall use  reasonable  efforts to (i) register
and qualify the Registrable Securities covered by the Registration  Statement(s)
under such other  securities  or "blue  sky" laws of such  jurisdictions  in the
United  States as any  Investor  reasonably  requests,  (ii) prepare and file in
those jurisdictions,  such amendments (including post-effective  amendments) and
supplements  to such  registrations  and  qualifications  as may be necessary to
maintain the effectiveness  thereof during the Registration  Period,  (iii) take
such other  actions as may be  necessary  to  maintain  such  registrations  and
qualifications in effect at all times during the Registration  Period,  and (iv)
take all  other  actions  reasonably  necessary  or  advisable  to  qualify  the
Registrable Securities for sale in such jurisdictions;  provided,  however, that
the  Company  shall not be required in  connection  therewith  or as a condition
thereto  to  qualify  to do  business  in any  jurisdiction  where it would  not
otherwise be required to qualify but for this Section 3(d),  (w) subject  itself
to general taxation in any such  jurisdiction,  or (x) file a general consent to
service of process in any such  jurisdiction,  which in each case,  the Board of
Directors of the Company  determines to be contrary to the best interests of the
Company and its  stockholders.  The Company shall promptly  notify each Investor
who  holds  Registrable  Securities  of  the  receipt  by  the  Company  of  any
notification with respect to the suspension of the registration or qualification
of any of the Registrable Securities for sale under the securities or "blue sky"
laws of any jurisdiction in the United States or its receipt of actual notice of
the initiation or threatening of any proceeding for such purpose.

                  e.  In  the  event  Investors  who  hold  a  majority  of  the
Registrable Securities being offered in the offering select underwriters for the
offering,  the Company  shall,  subject to Section 2(b)  hereof,  enter into and
perform its obligations under an underwriting  agreement, in usual and customary
form, including, without limitation,  customary indemnification and contribution
obligations, with the underwriters of such offering.

                  f. As promptly as  practicable  after  becoming  aware of such
event, the Company shall notify each Investor in writing of the happening of any
event as a result of which the prospectus included in a Registration  Statement,
as then in effect,  includes an untrue  statement of a material fact or omission
to state a material fact required to be stated  therein or necessary to make the
statements  therein,  in light of the circumstances  under which they were made,
not  misleading,   and  promptly  prepare  a  supplement  or  amendment  to  the
Registration  Statement to correct such untrue statement or omission and deliver
ten (10) copies of such  supplement or amendment to each Investor (or such other
number of copies as such  Investor may  reasonably  request).  The Company shall
also  promptly  notify each  Investor in writing  (i) when a  prospectus  or any
prospectus  supplement or  post-effective  amendment has been filed,  and when a
Registration  Statement or any  post-effective  amendment  has become  effective
(notification  of such  effectiveness  shall be  delivered  to each  Investor by
facsimile on the same day of such  effectiveness and by overnight mail), (ii) of
any request by the SEC for amendments or supplements to a Registration Statement
or  related  prospectus  or  related  information,  and  (iii) of the  Company's
reasonable  determination  that a  post-effective  amendment  to a  Registration
Statement would be appropriate.

                  Notwithstanding  the  foregoing,  the  Company  shall  not  be
required to promptly  supplement or amend the  Registration  Statement,  and the
Investors will  discontinue the

                                       -5-
<PAGE>

disposition of their securities covered by the Registration Statement during any
Blackout  Period (as defined below) (i) if the Board of Directors of the Company
determines  in good  faith  that  such  disposition  at such time  would  have a
material adverse effect upon a proposed sale of all or substantially  all of the
assets of the Company or a merger,  reorganization,  recapitalization or similar
current  transaction  materially  affecting  the  capital  structure  or  equity
ownership  of the Company or, (ii) if the Company is in  possession  of material
information which the Board of Directors of the Company determines in good faith
is not in the best  interests  of the  Company  to  disclose  in a  registration
statement at such time;  provided,  however,  that the Company may  require,  by
delivery of one or more Blackout  Notices,  that the Investors  discontinue from
time to time the  disposition of their  Securities  covered by the  Registration
Statement  for an  aggregate  period not to exceed  three (3) months  (each such
period, a "Blackout  Period") in any 24-month period. The Company shall promptly
notify  the  Holders  in  writing  (a  "Blackout  Notice")  of any  decision  to
discontinue sales of Registrable Securities pursuant to this Section 3(f), which
notice  shall set forth the reason for such  decision  (but not  disclosing  any
nonpublic  material  information  unless expressly  requested by Investors,  who
shall be obligated  to maintain the  confidentiality  of such  information)  and
shall include an undertaking by the Company  promptly to notify the Investors as
soon as sales may resume.

                  g. The  Company  shall use its best  efforts  to  prevent  the
issuance  of  any  stop  order  or  other   suspension  of  effectiveness  of  a
Registration  Statement,  or the suspension of the  qualification  of any of the
Registrable  Securities  for sale in any  jurisdiction  and, if such an order or
suspension  is issued,  to obtain the  withdrawal of such order or suspension at
the earliest  practicable time and to notify each Investor who holds Registrable
Securities  being  sold  (and,  in the event of an  underwritten  offering,  the
managing  underwriters) of the issuance of such order and the resolution thereof
or its receipt of actual notice of the  initiation  or threat of any  proceeding
for such purpose.

                  h. The Company shall permit each Investor and a single firm of
counsel,  initially Schulte Roth & Zabel LLP or such other counsel as thereafter
designated as selling stockholders' counsel by the Investors who hold a majority
of the  Registrable  Securities  being  sold,  to review  and  comment  upon the
Registration  Statement(s)  and all amendments and supplements  thereto at least
three (3) days prior to their  filing with the SEC, and not file any document in
a form to which such counsel reasonably objects.  The Company shall not submit a
request for acceleration of the effectiveness of a Registration  Statement(s) or
any amendment or supplement  thereto without the prior approval of such counsel,
which consent shall not be unreasonably withheld.

                  i. At the request of the  Investors who hold a majority of the
Registrable  Securities being sold, the Company shall furnish,  on the date that
Registrable  Securities  are  delivered to an  underwriter,  if any, for sale in
connection with the Registration Statement (i) if required by an underwriter,  a
letter,  dated  such  date,  from the  Company's  independent  certified  public
accountants  in form  and  substance  as is  customarily  given  by  independent
certified public accountants to underwriters in an underwritten public offering,
addressed to the  underwriters,  and (ii) an opinion,  dated as of such date, of
counsel representing the Company for purposes of such

                                       -6-
<PAGE>

Registration  Statement, in form, scope and substance as is customarily given in
an  underwritten  public  offering,   addressed  to  the  underwriters  and  the
Investors.

                  j. The Company shall make  available for inspection by (i) any
Investor,  (ii) any underwriter  participating in any disposition  pursuant to a
Registration Statement,  (iii) one firm of attorneys and one firm of accountants
or other  agents  retained  by the  Investors,  and  (iv) one firm of  attorneys
retained by all such underwriters (collectively, the "Inspectors") all pertinent
financial and other records, and pertinent corporate documents and properties of
the  Company  (collectively,  the  "Records"),  as  shall be  reasonably  deemed
necessary  by each  Inspector  to enable  each  Inspector  to  exercise  its due
diligence responsibility or otherwise which any Inspector may reasonably request
for purposes of due diligence; provided, however, that each Inspector shall hold
in strict  confidence and shall not make any  disclosure  (except to an Investor
who will also keep such information  confidential) or use of any Record or other
information which the Company  determines in good faith to be confidential,  and
of which determination the Inspectors are so notified, unless (a) the disclosure
of such Records is necessary to avoid or correct a  misstatement  or omission in
any Registration  Statement or is otherwise required under the 1933 Act, (b) the
release of such Records is ordered pursuant to a final,  non-appealable subpoena
or order from a court or government body of competent  jurisdiction,  or (c) the
information  in such  Records has been made  generally  available  to the public
other than by disclosure in violation of this  agreement.  Each Investor  agrees
that it shall,  upon learning that disclosure of such Records is sought in or by
a court or governmental  body of competent  jurisdiction or through other means,
give prompt  notice to the Company and allow the  Company,  at its  expense,  to
undertake appropriate action to prevent disclosure of, or to obtain a protective
order for,  the Records  deemed  confidential.  Nothing  herein (or in any other
confidentiality  agreement between the Company and any Investor) shall be deemed
to limit the Investors' ability to sell Registrable Securities in a manner which
is otherwise consistent with applicable laws and regulations.

                  k.  The  Company  shall  hold in  confidence  and not make any
disclosure of information  concerning an Investor provided to the Company unless
(i) disclosure of such  information is necessary to comply with federal or state
securities  laws, (ii) the disclosure of such  information is necessary to avoid
or correct a misstatement or omission in any Registration  Statement,  (iii) the
release of such  information  is ordered  pursuant to a subpoena or other final,
non-appealable   order  from  a  court  or   governmental   body  of   competent
jurisdiction,  or (iv) such information has been made generally available to the
public other than by disclosure in violation of this or any other agreement. The
Company agrees that it shall,  upon learning that disclosure of such information
concerning  an  Investor  is  sought  in or by a court or  governmental  body of
competent  jurisdiction  or through other means,  give prompt  written notice to
such Investor and allow such Investor,  at the Investor's  expense, to undertake
appropriate  action to prevent  disclosure  of, or to obtain a protective  order
for, such information.

                  l. The Company shall use its best efforts  either to (i) cause
all the Registrable  Securities covered by a Registration Statement to be listed
on each  securities  exchange  on which  securities  of the same class or series
issued  by the  Company  are  then  listed,  if  any,  if the  listing  of  such
Registrable  Securities is then permitted  under the rules of such

                                      -7-
<PAGE>

exchange,  or (ii)  secure  designation  and  quotation  of all the  Registrable
Securities  covered by the Registration  Statement on the Nasdaq National Market
System and,  without  limiting the generality of the  foregoing,  arrange for at
least two market makers to register with the National  Association of Securities
Dealers, Inc. as such with respect to such Registrable  Securities.  The Company
shall pay all fees and expenses in connection  with  satisfying  its  obligation
under this Section 3(l).

                  m. The Company  shall  cooperate  with the  Investors who hold
Registrable Securities being offered and, to the extent applicable, any managing
underwriter or underwriters,  to facilitate the timely  preparation and delivery
of  certificates   (not  bearing  any  restrictive   legend)   representing  the
Registrable  Securities to be offered  pursuant to a Registration  Statement and
enable such certificates to be in such denominations or amounts, as the case may
be, as the  managing  underwriter  or  underwriters,  if any, or, if there is no
managing  underwriter or underwriters,  the Investors may reasonably request and
registered in such names as the managing underwriter or underwriters, if any, or
the  Investors  may request.  Not later than the date on which any  Registration
Statement   registering  the  resale  of  Registrable   Securities  is  declared
effective,  the  Company  shall  deliver  to its  transfer  agent  instructions,
accompanied by any reasonably required opinion of counsel,  that permit sales of
unlegended  securities  in a timely  fashion that  complies  with then  mandated
securities settlement procedures for regular way market transactions.

                  n.  The  Company  shall  take  all  other  reasonable  actions
necessary to expedite and facilitate disposition by the Investors of Registrable
Securities pursuant to a Registration Statement.

                  o. The Company shall provide a CUSIP number,  a transfer agent
and registrar of all such  Registrable  Securities  not later than the effective
date of such Registration Statement.

                  p. If requested by the managing  underwriters  or an Investor,
the  Company  shall  immediately  incorporate  in  a  prospectus  supplement  or
post-effective  amendment such information as the managing  underwriters and the
Investors agree should be included therein relating to the sale and distribution
of Registrable  Securities,  including,  without  limitation,  information  with
respect to the number of Registrable Securities being sold to such underwriters,
the purchase price being paid therefor by such  underwriters and with respect to
any other terms of the underwritten (or best efforts  underwritten)  offering of
the  Registrable  Securities  to be sold in such  offering;  make  all  required
filings of such  prospectus  supplement or  post-effective  amendment as soon as
practicable  following  notice  of  the  matters  to  be  incorporated  in  such
prospectus  supplement  or  post-effective  amendment;  and  supplement  or make
amendments to any  Registration  Statement if requested by a shareholder  or any
underwriter of such Registrable Securities.

                  q. The  Company  shall  use its  best  efforts  to  cause  the
Registrable  Securities covered by the applicable  Registration  Statement to be
registered with or approved by such other

                                       -8-
<PAGE>

governmental  agencies or  authorities  as may be  necessary to  consummate  the
disposition of such Registrable Securities.

                  r. The Company shall  otherwise use its best efforts to comply
with all  applicable  rules and  regulations  of the SEC in connection  with any
registration hereunder.

         4.       OBLIGATIONS OF THE INVESTORS.

                  a. At least  seven  (7) days  prior to the  first  anticipated
filing  date of the  Registration  Statement,  the  Company  shall  notify  each
Investor or its counsel in writing of the information the Company  requires from
each  such  Investor  if such  Investor  elects  to have any of such  Investor's
Registrable  Securities  included in the Registration  Statement.  It shall be a
condition   precedent  to  the  obligations  of  the  Company  to  complete  the
registration  pursuant  to  this  Agreement  with  respect  to  the  Registrable
Securities  of a particular  Investor  that such  Investor  shall furnish to the
Company such information as may be requested in writing by the Company regarding
itself,  the  Registrable  Securities  held by it and  the  intended  method  of
disposition  of the  Registrable  Securities  held by it as shall be  reasonably
required to effect the  registration  of such  Registrable  Securities and shall
execute such documents in connection  with such  registration as the Company may
reasonably request.

                  b.  Each  Investor  by  such  Investor's   acceptance  of  the
Registrable  Securities  agrees to  cooperate  with the  Company  as  reasonably
requested by the Company in connection  with the  preparation  and filing of the
Registration  Statement(s)  hereunder  unless such  Investor  has  notified  the
Company in writing of such Investor's election to exclude all of such Investor's
Registrable Securities from the Registration Statement.

                  c. Each  Investor  agrees  that,  upon  receipt  of a Blackout
Notice or any notice from the Company of the  happening of any event of the kind
described  in Section 3(g) or the first  sentence of 3(f),  such  Investor  will
immediately  discontinue  disposition of Registrable  Securities pursuant to the
Registration  Statement(s)  covering  such  Registrable  Securities  until  such
Investor's  receipt of the  copies of the  supplemented  or  amended  prospectus
contemplated  by Section  3(g) or the first  sentence of 3(f) or notice from the
Company  that the  Blackout  Period has ended,  as the case may be,  and,  if so
directed by the  Company,  such  Investor  shall  deliver to the Company (at the
expense of the Company) or destroy all copies in such Investor's possession,  of
the  prospectus  covering  such  Registrable  Securities  current at the time of
receipt of such notice.

                  d.  No   Investor   may   participate   in  any   underwritten
registration  hereunder  unless such Investor (i) agrees to sell such Investor's
Registrable  Securities on the basis provided in any  underwriting  arrangements
approved by the Investors entitled hereunder to approve such arrangements,  (ii)
completes  and executes  all  questionnaires,  powers of attorney,  indemnities,
underwriting  agreements and other documents reasonably required under the terms
of such underwriting arrangements, and (iii) agrees to pay its pro rata share of
all underwriting discounts and commissions.

                                      -9-
<PAGE>

                  e. The Company shall be entitled to add the  following  legend
to the stock certificate  representing  Registrable Securities prior to the time
the securities represented thereby are sold to the public:

                  THE SECURITIES  REPRESENTED BY THIS CERTIFICATE ARE REGISTERED
UNDER THE  SECURITIES  ACT OF 1933,  AS AMENDED.  SALES OF SUCH  SECURITIES  ARE
SUBJECT TO CERTAIN  "BLACKOUT"  PERIODS  PURSUANT TO THE TERMS OF A REGISTRATION
RIGHTS AGREEMENT, A COPY OF WHICH IS ON FILE WITH THE COMPANY. THE HOLDER HEREOF
MUST AT ALL TIMES  FURNISH THE  COMPANY  WITH A CURRENT  ADDRESS  AND  FACSIMILE
NUMBER FOR THE DELIVERY OF A BLACKOUT NOTICE.

         5.       EXPENSES OF REGISTRATION.

                  All reasonable expenses, other than underwriting discounts and
commissions,   incurred   in   connection   with   registrations,   filings   or
qualifications pursuant to Sections 2 and 3, including,  without limitation, all
registration, listing and qualifications fees, printers and accounting fees, and
fees and  disbursements of counsel for the Company and fees and disbursements of
one  counsel for the  Investors  shall be paid by the Company up to a maximum of
$50,000 in the aggregate.

         6.       INDEMNIFICATION.

                  In the event any  Registrable  Securities  are  included  in a
Registration Statement under this Agreement:

                  a. To the fullest  extent  permitted by law, the Company will,
and hereby does,  indemnify,  hold  harmless and defend each  Investor who holds
such  Registrable  Securities,  the directors,  officers,  partners,  employees,
agents and each Person,  if any, who controls any Investor within the meaning of
the 1933 Act or the  Securities  Exchange  Act of 1934,  as  amended  (the "1934
Act"),  and any underwriter (as defined in the 1933 Act) for the Investors,  and
the  directors  and officers of, and each Person,  if any, who controls any such
underwriter  within  the  meaning  of the 1933 Act or the  1934  Act  (each,  an
"Indemnified  Person"),  against  any  losses,  claims,  damages,   liabilities,
judgments,  fines,  penalties,  charges, costs, attorneys' fees, amounts paid in
settlement or expenses, joint or several (collectively,  "Claims"),  incurred in
investigating,   preparing  or  defending  any  action,  claim,  suit,  inquiry,
proceeding,  investigation  or appeal taken from the  foregoing by or before any
court or governmental,  administrative or other regulatory  agency,  body or the
SEC,  whether pending or threatened,  whether or not an indemnified  party is or
may be a party thereto ("Indemnified  Damages"), to which any of them may become
subject insofar as such Claims (or actions or proceedings,  whether commenced or
threatened,  in respect  thereof) arise out of or are based upon: (i) any untrue
statement  or alleged  untrue  statement  of a material  fact in a  Registration
Statement  or any  post-effective  amendment  thereto or in any  filing  made in
connection with the  qualification of the offering under the securities or other
"blue sky" laws of any jurisdiction in which Registrable Securities are offered,
or the  omission  or alleged  omission to state a material  fact  required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances under which the statements therein were made, not

                                      -10-
<PAGE>

misleading,  (ii) any untrue statement or alleged untrue statement of a material
fact contained in any preliminary prospectus if used prior to the effective date
of such Registration Statement, or contained in the final prospectus (as amended
or  supplemented,  if the  Company  files any  amendment  thereof or  supplement
thereto with the SEC) or the omission or alleged  omission to state  therein any
material fact  necessary to make the  statements  made therein,  in light of the
circumstances  under which the statements therein were made, not misleading,  or
(iii) any  violation  or alleged  violation  by the Company of the 1933 Act, the
1934 Act, any other law,  including,  without  limitation,  any state securities
law, or any rule or regulation  thereunder  relating to the offer or sale of the
Registrable  Securities pursuant to a Registration Statement (the matters in the
foregoing clauses (i) through (iii) being, collectively,  "Violations"). Subject
to the  restrictions  set forth in  Section  6(d) with  respect to the number of
legal  counsel,  the  Company  shall  reimburse  the  Investors  and  each  such
underwriter  or controlling  person,  promptly as such expenses are incurred and
are due and payable, for any legal fees or other reasonable expenses incurred by
them  in   connection   with   investigating   or  defending   any  such  Claim.
Notwithstanding  anything to the contrary contained herein, the  indemnification
agreement contained in this Section 6(a): (i) shall not apply to a Claim arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information  furnished in writing to the Company by any Indemnified  Person
or underwriter for such Indemnified  Person expressly for use in connection with
the preparation of the Registration  Statement or any such amendment  thereof or
supplement  thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c); (ii) with respect to any preliminary prospectus, shall
not inure to the benefit of any such person from whom the person  asserting  any
such Claim purchased the Registrable Securities that are the subject thereof (or
to the benefit of any person controlling such person) if the untrue statement or
omission of material fact contained in the preliminary  prospectus was corrected
in the  prospectus,  as then amended or  supplemented,  if such  prospectus  was
timely  made  available  by the  Company  pursuant  to  Section  3(c),  and  the
Indemnified  Person was  promptly  advised in writing  not to use the  incorrect
prospectus  prior to the use giving  rise to a  Violation  and such  Indemnified
Person,  notwithstanding  such  advice,  used it;  and (iii)  shall not apply to
amounts paid in settlement of any Claim if such  settlement is effected  without
the  prior  written  consent  of  the  Company,   which  consent  shall  not  be
unreasonably  withheld.  Such  indemnity  shall  remain in full force and effect
regardless of any investigation  made by or on behalf of the Indemnified  Person
and shall  survive the transfer of the  Registrable  Securities by the Investors
pursuant to Section 9.

                  b. In connection with any  Registration  Statement in which an
Investor  is  participating,  each such  Investor  agrees to  severally  and not
jointly indemnify,  hold harmless and defend, to the same extent and in the same
manner as is set forth in Section  6(a),  the  Company,  each of its  directors,
officers,  employees,  agents and  representatives  and each Person, if any, who
controls  the  Company  within  the  meaning  of the  1933  Act or the  1934 Act
(collectively and together with an Indemnified Person, an "Indemnified  Party"),
against  any  Claim  or  Indemnified  Damages  to which  any of them may  become
subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim or
Indemnified  Damages arise out of or are based upon any Violation,  in each case
to the extent,  and only to the extent,  that such Violation  occurs in reliance
upon and in conformity with written information furnished to the Company by such
Investor expressly for use in connection with such Registration Statement;  and,
subject  to

                                      -11-
<PAGE>

Section  6(d),  such  Investor  will  reimburse  any  legal  or  other  expenses
reasonably  incurred by them in connection with  investigating  or defending any
such Claim;  provided,  however,  that the indemnity agreement contained in this
Section 6(b) and the agreement with respect to contribution contained in Section
7 shall not apply to amounts paid in settlement of any Claim if such  settlement
is effected  without the prior written  consent of such Investor,  which consent
shall  not be  unreasonably  withheld;  provided,  further,  however,  that  the
Investor shall be liable under this Section 6(b) for only that amount of a Claim
or  Indemnified  Damages as does not exceed the  proceeds to such  Investor as a
result  of the sale of  Registrable  Securities  pursuant  to such  Registration
Statement.  Such indemnity  shall remain in full force and effect  regardless of
any  investigation  made by or on  behalf  of such  Indemnified  Party and shall
survive the transfer of the Registrable  Securities by the Investors pursuant to
Section 9.  Notwithstanding  anything  to the  contrary  contained  herein,  the
indemnification  agreement  contained  in this  Section 6(b) with respect to any
preliminary  prospectus shall not inure to the benefit of any Indemnified  Party
if  the  untrue  statement  or  omission  of  material  fact  contained  in  the
preliminary  prospectus  was corrected on a timely basis in the  prospectus,  as
then amended or supplemented.

                  c. The Company shall be entitled to receive  indemnities  from
underwriters,  selling brokers,  dealer managers and similar securities industry
professionals participating in any distribution,  to the same extent as provided
above,  with  respect  to  information  such  persons  so  furnished  in writing
expressly for inclusion in the Registration Statement.

                  d.  Promptly  after  receipt  by  an  Indemnified   Person  or
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action or proceeding (including any governmental action or proceeding) involving
a Claim,  such  Indemnified  Person or  Indemnified  Party shall,  if a Claim in
respect thereof is to be made against any indemnifying  party under this Section
6,  deliver  to the  indemnifying  party a written  notice  of the  commencement
thereof,  and the  indemnifying  party shall have the right (at its  expense) to
participate in, and, to the extent the  indemnifying  party so desires,  jointly
with any other indemnifying  party similarly  noticed,  to assume control of the
defense thereof with counsel mutually satisfactory to the indemnifying party and
the Indemnified  Person or the Indemnified  Party, as the case may be; provided,
however,  that such indemnifying  party shall diligently pursue such defense and
that an Indemnified  Person or Indemnified  Party shall have the right to retain
its own counsel with the fees and expenses to be paid by the indemnifying party,
if, in the reasonable  opinion of counsel retained by the Indemnified  Person or
Indemnified Party, as the case may be, the representation by such counsel of the
Indemnified  Person or  Indemnified  Party and the  indemnifying  party would be
inappropriate  due to actual  or  potential  differing  interests  between  such
Indemnified  Person or Indemnified  Party. The Company shall pay reasonable fees
for only one separate  legal counsel for the  Investors,  and such legal counsel
shall be  selected  by the  Investors  holding a  majority  in  interest  of the
Registrable Securities included in the Registration Statement to which the Claim
relates.  The Indemnified Party or Indemnified Person shall cooperate fully with
the indemnifying party in connection with any negotiation or defense of any such
action or claim by the indemnifying  party and shall furnish to the indemnifying
party  all  information   reasonably  available  to  the  Indemnified  Party  or
Indemnified Person which relates to such action or claim. The indemnifying party
shall keep the  Indemnified  Party or  Indemnified  Person fully apprised at all
times as to the  status  of the  defense  or any  settlement  negotiations  with
respect thereto. No

                                      -12-
<PAGE>

indemnifying  party shall be liable for any  settlement of any action,  claim or
proceeding  effected without its written consent,  provided,  however,  that the
indemnifying  party shall not  unreasonably  withhold,  delay or  condition  its
consent.  No indemnifying  party shall,  without such consent of the Indemnified
Party or Indemnified Person,  consent to entry of any judgment or enter into any
settlement or other compromise  which does not include as an unconditional  term
thereof the giving by the  claimant or plaintiff  to such  Indemnified  Party or
Indemnified  Person of a release from all  liability in respect to such claim or
litigation.   Following   indemnification   as  provided  for   hereunder,   the
indemnifying party shall be subrogated to all rights of the Indemnified Party or
Indemnified  Person with  respect to all third  parties,  firms or  corporations
relating to the matter for which  indemnification  has been made. The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve such indemnifying party of any
liability to the Indemnified  Person or Indemnified  Party under this Section 6,
except to the extent that the indemnifying party is prejudiced in its ability to
defend such action.

                  e.  The  indemnity  agreements  contained  herein  shall be in
addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified  Person  against  the  indemnifying  party or  others,  and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

         7.       CONTRIBUTION.

                  To the extent any  indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying  party agrees to make the maximum
contribution  with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no contribution shall be made under  circumstances where the maker would not
have been  liable for  indemnification  under the fault  standards  set forth in
Section  6; (ii) no  seller  of  Registrable  Securities  guilty  of  fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution  from any seller of Registrable  Securities who was not
guilty of fraudulent  misrepresentation;  and (iii) contribution  (together with
any  indemnification or other obligations under this Agreement) by any seller of
Registrable  Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities.

         8.       REPORTS UNDER THE 1934 ACT.

                  With a view to making  available to the Investors the benefits
of Rule  144  promulgated  under  the  1933  Act or any  other  similar  rule or
regulation  of the  SEC  that  may at any  time  permit  the  Investors  to sell
securities of the Company to the public without  registration  ("Rule 144"), the
Company  agrees that so long as any Investor  owns any  Securities,  the Company
shall:

                  a. make and keep public information available,  as those terms
are understood and defined in Rule 144;

                                      -13-
<PAGE>

                  b. file with the SEC in a timely  manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company  remains  subject to such  requirements  (it being  understood  that
nothing herein shall limit the Company's  obligations  under Section 4(c) of the
Securities  Purchase  Agreement)  and the  filing  of  such  reports  and  other
documents is required for the applicable provisions of Rule 144; and

                  c.  furnish to each  Investor  so long as such  Investor  owns
Registrable  Securities,  promptly upon request,  (i) a written statement by the
Company that it has complied  with the reporting  requirements  of Rule 144, the
1933 Act and the 1934 Act,  (ii) a copy of the most recent  annual or  quarterly
report of the  Company  and such other  reports  and  documents  so filed by the
Company,  and (iii) such other  information  as may be  reasonably  requested to
permit  the  Investors  to sell such  securities  pursuant  to Rule 144  without
registration.

         9.       ASSIGNMENT OF REGISTRATION RIGHTS.

                  The rights to have the Company register Registrable Securities
pursuant to this Agreement shall be automatically assignable by the Investors to
any transferee or assignee (a "Transferee") of all or any portion of Registrable
Securities if: (i) the Investor  agrees in writing with the Transferee to assign
such rights,  and a copy of such  agreement is furnished to the Company within a
reasonable time after such assignment;  (ii) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (a) the
name and address of such  Transferee,  and (b) the  securities  with  respect to
which  such  registration  rights  are  being  transferred  or  assigned;  (iii)
immediately  following  such transfer or assignment  the further  disposition of
such  securities  by the  Transferee  is  restricted  under  the  1933  Act  and
applicable  state  securities  laws;  (iv) at or  before  the time  the  Company

substitution therefor) originally issued pursuant to the terms of the Securities

bid price of such  security  in the  over-the-counter  market on the  electronic

price is reported for such security by Bloomberg,  the average of the bid prices
of any market  makers for such  security as reported in the "pink sheets" by the
National  Quotation  Bureau,  Inc. If the Closing Bid Price cannot be calculated
for such  security on such date,  as set forth  above,  the Closing Bid Price of
such  security  shall be the fair market value as determined in good faith by an
investment  banking firm selected  jointly by the Company and the Holders,  with

This Warrant may be exercised by the Holder, in whole or in part, at any time or
from time to time prior to the Expiration  Date, by  surrendering to the Company
at its  principal  office (or such other  office or agency of the Company as the
Company may designate in a written notice to the Holder) this Warrant,  together
with the form of Election to Purchase  Shares attached hereto as Exhibit A (or a
reasonable  facsimile  thereof) duly executed by the Holder and  accompanied  by
payment of the Purchase Price for the number of shares of Common Stock specified
in such form.

                  (b) Payment of the  Purchase  Price may be made as follows (or
by any combination of the  following):  (i) in United States currency by cash or
delivery of a certified  check or bank draft payable to the order of the Company
or by wire transfer to the account of the Company,  (ii) by cancellation of such
number of the shares of Common Stock otherwise  issuable to the Holder upon such
exercise as shall be specified in such  Election to Purchase  Shares,  such that
the excess of the Current Market Price of such specified number of shares on the
date of exercise  over the portion of the Purchase  Price  attributable  to such
shares shall equal the Purchase Price attributable to the shares of Common Stock
to be issued upon such exercise, in


                                       4
<PAGE>

which case upon delivery of such notice such amount shall be deemed to have been
paid to the Company and the number of shares  issuable upon such exercise  shall
be reduced by such  specified  number,  or (iii) by surrender to the Company for
cancellation,  certificates  representing  shares of Common Stock of the Company
owned by the Holder  (properly  endorsed for transfer in blank) having a Current
Market Price on the date of Warrant exercise equal to the Purchase Price.

                  2.2.  When Exercise  Effective.  Each exercise of this Warrant
shall be deemed to have been effected immediately prior to the close of business
on the Business Day on which this Warrant  shall have been  surrendered  to, and
the  Purchase  Price  shall have been  received  by, the  Company as provided in
Section  2.1,  and at such time the Person or Persons in whose name or names any
certificate  or  certificates  for shares of Common Stock (or Other  Securities)
shall be issuable  upon such exercise as provided in Section 2.3 shall be deemed
to have become the holder or holders of record thereof for all purposes.

                  2.3. Delivery of Stock Certificates,  etc.; Charges, Taxes and
Expenses.  (a) As soon as  practicable  after each exercise of this Warrant,  in
whole or in part,  and in any event within three Business Days  thereafter,  the
Company  shall cause to be issued in such  denominations  as may be requested by
Holder in the Election to Purchase  Shares,  in the name of and delivered to the
Holder or, subject the Purchase Agreement, as the Holder may direct,

                  (i) a certificate  or  certificates,  or, if then  permissible
         under the Securities Act and the Registration  Rights  Agreement,  at a
         Holder's  request to  electronically  issue such shares (e.g.,  through
         DWAC or DTC),  for the  number  of  shares  of  Common  Stock (or Other
         Securities)  to which the Holder shall be entitled  upon such  exercise
         plus, in lieu of issuance of any  fractional  share to which the Holder
         would  otherwise be entitled,  if any, a certified check for the amount
         of cash equal to the same  fraction  multiplied  by the Current  Market
         Price per share on the date of Warrant exercise, and

                  (ii) in case such  exercise is for less than all of the shares
         of Common  Stock  purchasable  under  this  Warrant,  a new  Warrant or
         Warrants of like tenor,  for the balance of the shares of Common  Stock
         purchasable hereunder.

                  (b) Issuance of  certificates  for shares of Common Stock upon
the exercise of this Warrant  shall be made without  charge to the Holder hereof
for any issue or transfer  tax or other  incidental  expense,  in respect of the
issuance of such  certificates,  all of which such taxes and  expenses  shall be
paid by the Company.

                  2.4.  Company to Reaffirm  Obligations.  The Company shall, at
the time of each  exercise  of this  Warrant,  upon the  request  of the  Holder
hereof,  acknowledge  in writing  its  continuing  obligation  to afford to such
Holder all rights to which such Holder shall  continue to be entitled after such
exercise in  connection  with the Common Stock yet to be acquired  upon exercise
hereof in accordance with the terms of this Warrant, provided that if the Holder
of this Warrant  shall fail to make any such  request,  such  failure  shall not
affect the  continuing  obligation  of the  Company to afford such rights to the
Holder.

                  3.       Adjustment of Common Stock Issuable Upon Exercise.

                  3.1.     Adjustment of Number of Shares.

                           Upon  each  adjustment  of the  Purchase  Price  as a
result of the calculations made in this Section 3, this Warrant shall thereafter
evidence the right to receive,  at the adjusted  Purchase Price,  that number of
shares of Common Stock  (calculated  to the nearest  one-hundredth)  obtained by
dividing  (i) the  product  of the  aggregate  number of shares  covered by this
Warrant  immediately  prior to such  adjustment and the Purchase Price in effect
immediately  prior to such adjustment of the Purchase Price by (ii) the Purchase
Price in effect immediately after such adjustment of the Purchase Price.

                  3.2.     Adjustment of Purchase Price.

                  3.2.1.  Issuance of Additional Shares of Common Stock. In case
the Company at any time or from time to time after the date  hereof  shall issue
or sell Additional Shares of Common Stock (including Additional Shares of Common
Stock  deemed  to be  issued  pursuant  to  Section  3.3  or 3.4  but  excluding
Additional  Shares of Common Stock  purchasable upon exercise of Rights referred
to in  Section  3.10),  other  than in a  registered  public  offering,  without
consideration  or for a  consideration  per share  less than 95% of the  Current
Market Price (or if the issuance  involves more than 10% of the number of shares
of Common  Stock  outstanding  immediately  prior to such  issue,  less than the
Current  Market  Price) as in effect  immediately  prior to such  issue or sale,
then, and in each such case, subject to Section 3.8, the Purchase Price shall be
reduced,  concurrently  with such issue or sale, to a price  (calculated  to the
nearest .001 of a cent)  determined  by  multiplying  such  Purchase  Price by a
fraction

                  (a) the  numerator of which shall be the sum of (i) the number
         of shares of Common Stock  outstanding  immediately prior to such issue
         or sale and (ii) the number of shares of Common  Stock  which the gross
         consideration  received  by the  Company  for the total  number of such
         Additional  Shares of Common Stock so issued or sold would  purchase at
         such Current Market Price, and

                  (b) the  denominator of which shall be the number of shares of
         Common Stock outstanding immediately after such issue or sale, provided
         that, for the purposes of this Section 3.2.1, (x) immediately after any
         Additional  Shares of  Common  Stock  are  deemed  to have been  issued
         pursuant to Section 3.3 or 3.4, such Additional  Shares shall be deemed
         to be  outstanding,  and (y) treasury  shares shall not be deemed to be
         outstanding.

                  3.2.2. Extraordinary Dividends and Distributions.  In case the
Company at any time or from time to time after the date  hereof  shall  declare,
order,  pay  or  make a  dividend  or  other  distribution  (including,  without
limitation, any distribution of other or additional stock or other securities or
property  or  Options  by  way  of  dividend  or   spin-off,   reclassification,
recapitalization or similar corporate  rearrangement) on the Common Stock, then,
in each  such  case,  subject  to  Section  3.8,  the  Purchase  Price in effect
immediately  prior to the close of  business  on the  record  date fixed for the
determination  of holders of any class of  securities  entitled to receive  such
dividend or distribution shall be reduced, effective as of the close of


                                       6
<PAGE>

business on such record date, to a price determined by multiplying such Purchase
Price by a fraction

                  (x) the  numerator of which shall be the Current  Market Price
         in effect on such  record  date or, if the  Common  Stock  trades on an
         ex-dividend basis, on the date prior to the commencement of ex-dividend
         trading,   less  the  Fair  Value  of  such  dividend  or  distribution
         applicable to one share of Common Stock, and

                  (y) the  denominator  of which  shall be such  Current  Market
         Price.

                  3.3. Treatment of Options and Convertible Securities.  In case
the Company at any time or from time to time after the date hereof  shall issue,
sell,  grant or  assume,  or shall fix a record  date for the  determination  of
holders of any class of  securities  of the Company  entitled  to  receive,  any
Options or  Convertible  Securities  (whether or not the rights  thereunder  are
immediately  exercisable),  then,  and in each such case,  the maximum number of
Additional  Shares of Common  Stock  (as set  forth in the  instrument  relating
thereto,  without  regard to any provisions  contained  therein for a subsequent
adjustment of such number) issuable upon the exercise of such Options or, in the
case of Convertible  Securities and Options therefor, the conversion or exchange
of such  Convertible  Securities,  shall be  deemed to be  Additional  Shares of
Common Stock issued as of the time of such issue,  sale, grant or assumption or,
in case such a record date shall have been fixed, as of the close of business on
such record date (or, if the Common Stock trades on an ex-dividend basis, on the
date prior to the  commencement  of  ex-dividend  trading),  provided  that such
Additional Shares of Common Stock shall not be deemed to have been issued unless
(i) the  consideration  per share  (determined  pursuant to Section 3.5) of such
shares would be less than the Current  Market Price in effect on the date of and
immediately prior to such issue,  sale, grant or assumption or immediately prior
to the close of business on such record date (or, if the Common  Stock trades on
an  ex-dividend  basis,  on the date prior to the  commencement  of  ex-dividend
trading), as the case may be and (ii) such Additional Shares of Common Stock are
not  purchasable  pursuant to Rights  referred to in Section 3.10, and provided,
further, that

                  (a)  whether  or not the  Additional  Shares of  Common  Stock
         underlying  such  Options or  Convertible  Securities  are deemed to be
         issued, no further  adjustment of the Purchase Price shall be made upon
         the  subsequent  issue or sale of  Convertible  Securities or shares of
         Common  Stock upon the exercise of such  Options or the  conversion  or
         exchange of such Convertible Securities;

                  (b) if such Options or  Convertible  Securities by their terms
         provide, with the passage of time or otherwise, for any increase in the
         consideration  payable to the  Company,  or  decrease  in the number of
         Additional  Shares  of  Common  Stock  issuable,   upon  the  exercise,
         conversion or exchange  thereof (by change of rate or  otherwise),  the
         Purchase  Price  computed  upon  the  original  issue,  sale,  grant or
         assumption  thereof (or upon the occurrence of the record date, or date
         prior to the commencement of ex-dividend  trading,  as the case may be,
         with respect  thereto),  and any subsequent  adjustments based thereon,
         shall,  upon any such  increase  or  decrease  becoming  effective,  be
         recomputed to


                                       7
<PAGE>

         reflect such  increase or decrease  insofar as it affects such Options,
         or  the  rights  of  conversion  or  exchange  under  such  Convertible
         Securities, which are outstanding at such time;

                  (c) upon the  expiration  or  termination  (or purchase by the
         Company and cancellation or retirement) of any such Options which shall
         not have been  exercised or the  expiration of any rights of conversion
         or exchange under any such Convertible Securities which (or purchase by
         the Company and  cancellation  or  retirement  of any such  Convertible
         Securities  the rights of conversion or exchange under which) shall not
         have been  exercised,  the Purchase  Price  computed  upon the original
         issue, sale, grant or assumption thereof (or upon the occurrence of the
         record date, or date prior to the commencement of ex-dividend  trading,
         as  the  case  may  be,  with  respect  thereto),  and  any  subsequent
         adjustments  based  thereon,  shall,  upon  such  expiration  (or  such
         cancellation or retirement, as the case may be), be recomputed as if:

                           (i) in the  case  of  Options  for  Common  Stock  or
                  Convertible  Securities,  the only Additional Shares of Common
                  Stock  issued  or sold  were the  Additional  Shares of Common
                  Stock,  if any,  actually  issued or sold upon the exercise of
                  such Options or the conversion or exchange of such Convertible
                  Securities  and the  consideration  received  therefor was the
                  consideration  actually received by the Company for the issue,
                  sale, grant or assumption of all such Options,  whether or not
                  exercised,  plus the  consideration  actually  received by the
                  Company  upon such  exercise,  or for the issue or sale of all
                  such Convertible  Securities which were actually  converted or
                  exchanged, plus the additional consideration, if any, actually
                  received by the Company upon such conversion or exchange, and

                           (ii)  in  the  case  of   Options   for   Convertible
                  Securities,  only the Convertible Securities, if any, actually
                  issued or sold upon the  exercise of such  Options were issued
                  at the time of the issue or sale,  grant or assumption of such
                  Options, and the consideration received by the Company for the
                  Additional  Shares  of Common  Stock  deemed to have then been
                  issued was the consideration  actually received by the Company
                  for the issue,  sale, grant or assumption of all such Options,
                  whether or not  exercised,  plus the  consideration  deemed to
                  have been  received by the Company  (pursuant  to Section 3.5)
                  upon the  issue or sale of such  Convertible  Securities  with
                  respect to which such Options were actually exercised;

                  (d) no  readjustment  pursuant to subdivision (b) or (c) above
         shall have the effect of increasing  the Purchase Price by an amount in
         excess  of the  amount of the  adjustment  thereof  originally  made in
         respect of the issue,  sale,  grant or  assumption  of such  Options or
         Convertible Securities; and

                  (e) in the  case of any such  Options  which  expire  by their
         terms not more than 30 days  after  the date of issue,  sale,  grant or
         assumption  thereof,  no adjustment of the


                                       8
<PAGE>

         Purchase  Price shall be made until the  expiration  or exercise of all
         such Options,  whereupon  such  adjustment  shall be made in the manner
         provided in subdivision (c) above.

                  3.4. Treatment of Stock Dividends,  Stock Splits, etc. In case
the Company at any time or from time to time after the date hereof shall declare
or pay any dividend on the Common Stock payable in Common Stock, or shall effect
a subdivision of the outstanding shares of Common Stock into a greater number of
shares of Common Stock (by  reclassification  or otherwise  than by payment of a
dividend in Common  Stock),  then, and in each such case,  Additional  Shares of
Common  Stock  shall be deemed to have been  issued  (a) in the case of any such
dividend,  immediately  after the close of  business  on the record date for the
determination  of holders of any class of  securities  entitled to receive  such
dividend,  or (b) in the case of any such subdivision,  at the close of business
on the day immediately prior to the day upon which such corporate action becomes
effective.

                  3.5.  Computation of  Consideration.  For the purposes of this
Section 3,

                  (a) the  consideration for the issue or sale of any Additional
         Shares of Common Stock shall,  irrespective of the accounting treatment
         of such consideration,

                           (i) insofar as it  consists  of cash,  be computed at
                  the amount of cash received by the Company,  without deducting
                  any   expenses   paid  or  incurred  by  the  Company  or  any
                  commissions or compensations  paid or concessions or discounts
                  allowed to underwriters,  dealers or others performing similar
                  services in connection with such issue or sale,

                           (ii)  insofar as it consists  of property  (including
                  securities)  other than cash,  be  computed  at the Fair Value
                  thereof at the time of such issue or sale, and

                           (iii) in case  Additional  Shares of Common Stock are
                  issued or sold  together  with other  stock or  securities  or
                  other assets of the Company for a  consideration  which covers
                  both,  be the  portion  of  such  consideration  so  received,
                  computed as provided in clauses (i) and (ii) above,  allocable
                  to such Additional  Shares of Common Stock, such allocation to
                  be  determined  in the same  manner  that  the  Fair  Value of
                  property  not  consisting  of  cash  or  securities  is  to be
                  determined  as  provided  in the  definition  of 'Fair  Value'
                  herein;

                  (b)  Additional  Shares  of Common  Stock  deemed to have been
         issued  pursuant to Section  3.3,  relating to Options and  Convertible
         Securities, shall be deemed to have been issued for a consideration per
         share determined by dividing

                           (i) the total amount, if any, received and receivable
                  by the Company as consideration for the issue,  sale, grant or
                  assumption  of  the  Options  or  Convertible   Securities  in
                  question,  plus the  minimum  aggregate  amount of  additional
                  consideration  (as  set  forth  in  the  instruments  relating
                  thereto, without regard to any provision contained therein for
                  a  subsequent  adjustment  of such


                                       9
<PAGE>

                  consideration  to  protect  against  dilution)  payable to the
                  Company  upon  the  exercise  in full of such  Options  or the
                  conversion or exchange of such  Convertible  Securities or, in
                  the case of Options for Convertible  Securities,  the exercise
                  of such Options for Convertible  Securities and the conversion
                  or  exchange  of such  Convertible  Securities,  in each  case
                  computing  such  consideration  as provided  in the  foregoing
                  subdivision (a),

                  by

                           (ii) the maximum number of shares of Common Stock (as
                  set forth in the instruments relating thereto,  without regard
                  to any provision contained therein for a subsequent adjustment
                  of such number to protect against dilution)  issuable upon the
                  exercise of such Options or the conversion or exchange of such
                  Convertible Securities; and

                  (c)  Additional  Shares  of Common  Stock  deemed to have been
         issued  pursuant to Section  3.4,  relating to stock  dividends,  stock
         splits, etc., shall be deemed to have been issued for no consideration.

                  3.6.   Adjustments   for   Combinations,   etc.  In  case  the
outstanding  shares  of Common  Stock  shall be  combined  or  consolidated,  by
reclassification  or otherwise,  into a lesser number of shares of Common Stock,
the  Purchase  Price  in  effect   immediately  prior  to  such  combination  or
consolidation shall,  concurrently with the effectiveness of such combination or
consolidation, be proportionately increased.

                  3.7. Dilution in Case of Other  Securities.  In case any Other
Securities shall be issued or sold or shall become subject to issue or sale upon
the conversion or exchange of any stock (or Other Securities) of the Company (or
any issuer of Other  Securities or any other Person referred to in Section 4) or
to subscription, purchase or other acquisition pursuant to any Options issued or
granted by the Company (or any such other issuer or Person) for a  consideration
such as to dilute,  on a basis consistent with the standards  established in the
other  provisions of this Section 3, the purchase rights granted by this Warrant
(other than in  circumstances  comparable to those described in clauses (a), (b)
or (c) of the definition of "Additional  Shares of Common Stock"),  then, and in
each such case, the computations,  adjustments and readjustments provided for in
this  Section 3 with  respect  to the  Purchase  Price and the  number of shares
purchasable  upon  Warrant  exercise  shall be made as nearly as possible in the
manner so provided and applied to determine the amount of Other  Securities from
time to time receivable upon the exercise of the Warrants,  so as to protect the
holders of the Warrants against the effect of such dilution.

                  3.8. De Minimis  Adjustments.  If the amount of any adjustment
of the  Purchase  Price per share  required  pursuant to this Section 3 would be
less than $.01, such amount shall be carried forward and adjustment with respect
thereto made at the time of and together with any subsequent  adjustment  which,
together  with such amount and any other  amount or amounts so carried  forward,
shall  aggregate a change in the Purchase Price of at least $.01 per share.  All
calculations  under this Warrant  shall be made to the nearest .001 of a cent or
to the nearest one-hundredth of a share, as the case may be.


                                       10
<PAGE>

                  3.9. Abandoned Dividend or Distribution.  If the Company shall
take a record of the holders of its Common  Stock for the  purpose of  entitling
them to receive a dividend or other distribution (which results in an adjustment
to the Purchase  Price under the terms of this  Warrant) and shall,  thereafter,
and before such dividend or  distribution  is paid or delivered to  stockholders
entitled  thereto,  legally  abandon its plan to pay or deliver such dividend or
distribution,  then any  adjustment  made to the  Purchase  Price and  number of
shares of Common Stock purchasable upon Warrant exercise by reason of the taking
of such record shall be reversed, and any subsequent adjustments, based thereon,
shall be recomputed.

                  3.10. Shareholder Rights Plan.  Notwithstanding the foregoing,
in the event that the Company shall distribute  "poison pill" rights pursuant to
a "poison pill"  shareholder  rights plan (the "Rights"),  the Company shall, in
lieu of making any adjustment pursuant to Section 3.2.1 or Section 3.2.2 hereof,
make  proper  provision  so that each Holder who  exercises a Warrant  after the
record date for such  distribution  and prior to the expiration or redemption of
the Rights shall be entitled to receive upon such  exercise,  in addition to the
shares of Common Stock  issuable  upon such  exercise,  a number of Rights to be
determined as follows:  (i) if such exercise  occurs on or prior to the date for
the  distribution to the holders of Rights of separate  certificates  evidencing
such  Rights  (the  "Distribution  Date"),  the same number of Rights to which a
holder of a number of shares of Common  Stock  equal to the  number of shares of
Common Stock  issuable upon such exercise at the time of such exercise  would be
entitled in accordance  with the terms and  provisions of and  applicable to the
Rights;  and (ii) if such exercise occurs after the Distribution  Date, the same
number  of Rights to which a holder  of the  number  of  shares  into  which the
Warrant so exercised was exercisable  immediately prior to the Distribution Date
would have been entitled on the  Distribution  Date in accordance with the terms
and provisions of and applicable to the Rights,  and in each case subject to the
terms and conditions of the Rights.

                  4.       Consolidation, Merger, etc.

                  4.1.  Adjustments for Consolidation,  Merger,  Sale of Assets,
Reorganization,  etc.  In case the  Company  after  the date  hereof  (a)  shall
consolidate  with or merge into any other Person and shall not be the continuing
or surviving  corporation of such  consolidation or merger,  or (b) shall permit
any other Person to  consolidate  with or merge into the Company and the Company
shall be the  continuing  or  surviving  Person  but,  in  connection  with such
consolidation  or merger,  the Common Stock or Other Securities shall be changed
into or exchanged  for stock or other  securities of any other Person or cash or
any  other  property,  or (c) shall  transfer  all or  substantially  all of its
properties  or  assets  to any  other  Person,  or (d)  shall  effect a  capital
reorganization  or  reclassification  of the  Common  Stock or Other  Securities
(other than a capital reorganization or reclassification  resulting in the issue
of Additional  Shares of Common Stock for which adjustment in the Purchase Price
is  provided  in  Section  3.2.1 or 3.2.2),  then,  and in the case of each such
transaction,  proper  provision  shall be made so that,  upon the  basis and the
terms and in the manner  provided in this  Warrant,  the Holder of this Warrant,
upon the exercise hereof at any time after the  consummation of such transaction
shall be entitled to receive (at the aggregate  Purchase  Price in effect at the
time of such consummation for all Common Stock or Other Securities issuable upon
such exercise  immediately  prior to such  consummation),  in lieu of the Common
Stock  or  Other   Securities   issuable  upon  such  exercise   prior  to  such
consummation,


                                       11
<PAGE>

the amount of  securities,  cash or other  property to which such  Holder  would
actually  have been  entitled as a stockholder  upon such  consummation  if such
Holder  had  exercised  this  Warrant  immediately  prior  thereto,  subject  to
adjustments  (subsequent to such  consummation) as nearly equivalent as possible
to the adjustments provided for in Sections 3 through 5.

                  4.2.  Assumption  of  Obligations.   Notwithstanding  anything
contained  in the Warrants or in the Purchase  Agreement  to the  contrary,  the
Company  shall not  effect any of the  transactions  described  in  clauses  (a)
through (d) of Section  4.1  unless,  prior to the  consummation  thereof,  each
Person  (other  than the  Company)  which may be  required to deliver any stock,
securities,  cash or  property  upon the  exercise  of this  Warrant as provided
herein  shall  assume,  by  written  instrument  delivered  to,  and  reasonably
satisfactory to, the Holder of this Warrant,  (a) the obligations of the Company
under this Warrant (and if the Company  shall survive the  consummation  of such
transaction,  such assumption shall be in addition to, and shall not release the
Company from, any continuing obligations of the Company under this Warrant), (b)
the obligations of the Company under the Purchase Agreement and the Registration
Rights  Agreement and (c) the obligation to deliver to the Holder such shares of
stock,  securities,  cash or  property  as,  in  accordance  with the  foregoing
provisions of this Section 4, the Holder may be entitled to receive.  Nothing in
this  Section 4 shall be deemed  to  authorize  the  Company  to enter  into any
transaction not otherwise permitted by the Purchase Agreement.

                  5. Other Dilutive Events.  In case any event shall occur as to
which  the  provisions  of  Section  3 or  Section  4  hereof  are not  strictly
applicable  or if strictly  applicable  would not fairly  protect  the  purchase
rights of the Holder in accordance  with the essential  intent and principles of
such  Sections,  then, in each such case,  the Board of Directors of the Company
shall make an adjustment in the  application of such  provisions,  in accordance
with such essential intent and principles, so as to preserve,  without dilution,
the purchase rights represented by this Warrant.

                  6. No  Dilution  or  Impairment.  The  Company  shall not,  by
amendment of its  certificate  of  incorporation  or through any  consolidation,
merger,  reorganization,  transfer  of  assets,  dissolution,  issue  or sale of
securities or any other voluntary action,  avoid or seek to avoid the observance
or  performance  of any of the terms of this  Warrant,  but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such action as may be reasonably  necessary or  appropriate  in order to protect
the rights of the Holder of this Warrant against  dilution or other  impairment.
Without  limiting the  generality  of the  foregoing,  the Company (a) shall not
permit the par value of any shares of stock receivable upon the exercise of this
Warrant to exceed the amount payable therefor upon such exercise, (b) shall take
all such action as may be necessary or appropriate in order that the Company may
validly and legally  issue fully paid and  nonassessable  shares of stock,  free
from all taxes, liens, security interests,  encumbrances,  preemptive rights and
charges on the exercise of the Warrants from time to time outstanding, (c) shall
not take any action which results in any adjustment of the Purchase Price if the
total number of shares of Common Stock (or Other Securities)  issuable after the
action upon the exercise of all of the Warrants would exceed the total number of
shares of Common Stock (or Other  Securities)  then  authorized by the Company's
certificate  of  incorporation  and available for the purpose of issue upon such
exercise,  and (d)  shall  not issue


                                       12
<PAGE>

any capital  stock of any class which is  preferred as to dividends or as to the
distribution of assets upon voluntary or involuntary dissolution, liquidation or
winding-up, unless the rights of the holders thereof shall be limited to a fixed
sum or  percentage  of par value or a sum  determined  by reference to a formula
based  on a  published  index of  interest  rates,  an  interest  rate  publicly
announced by a financial institution or a similar indicator of interest rates in
respect of  participation  in dividends  and to a fixed sum or percentage of par
value in any such distribution of assets.

                  7.  Certificate  as  to  Adjustments.  In  each  case  of  any
adjustment or readjustment  in the shares of Common Stock (or Other  Securities)
issuable  upon the exercise of this  Warrant,  the Company at its expense  shall
promptly compute such adjustment or readjustment in accordance with the terms of
this  Warrant and prepare a  certificate,  signed by the  Chairman of the Board,
President  or one of the  Vice  Presidents  of  the  Company,  and by the  Chief
Financial  Officer,  the  Treasurer or one of the  Assistant  Treasurers  of the
Company, setting forth such adjustment or readjustment and showing in reasonable
detail  the  method  of  calculation  thereof  and the  facts  upon  which  such
adjustment  or  readjustment  is  based,   including  a  statement  of  (a)  the
consideration  received or to be  received  by the  Company  for any  Additional
Shares of Common  Stock  issued or sold or deemed to have been  issued,  (b) the
number of shares of Common Stock  outstanding or deemed to be  outstanding,  and
(c) the Purchase Price in effect  immediately prior to such issue or sale and as
adjusted  and  readjusted  (if  required by Section 3) on account  thereof.  The
Company shall forthwith mail a copy of each such certificate to each holder of a
Warrant  and  shall,  upon the  written  request  at any time of any holder of a
Warrant, furnish to such holder a like certificate.  The Company shall also keep
copies of all such certificates at its principal office and shall cause the same
to be available for  inspection at such office during normal  business  hours by
any holder of a Warrant or any prospective  purchaser of a Warrant designated by
the holder thereof. The Company shall, upon the request in writing of the Holder
(at the Company's expense),  retain independent public accountants of recognized
national  standing selected by the Board of Directors of the Company to make any
computation  required in connection with adjustments  under this Warrant,  and a
certificate signed by such firm shall be conclusive  evidence of the correctness
of such adjustment, which shall be binding on the Holder and the Company.

                  8. Notices of Corporate Action. In the event of:

                  (a) any taking by the  Company  of a record of the  holders of
         any class of  securities  for the  purpose of  determining  the holders
         thereof who are entitled to receive any dividend or other distribution,
         or any right to subscribe for, purchase or otherwise acquire any shares
         of stock of any  class  or any  other  securities  or  property,  or to
         receive any other right, or

                  (b)  any   capital   reorganization   of  the   Company,   any
         reclassification  or  recapitalization  of  the  capital  stock  of the
         Company,  any  consolidation  or merger  involving  the Company and any
         other Person,  any  transaction or series of transactions in which more
         than 50% of the voting  securities  of the Company are  transferred  to
         another


                                       13
<PAGE>

         Person,  or   any  transfer,  sale  or  other  disposition  of  all  or
         substantially all the assets of the Company to any other Person, or

                  (c) any voluntary or involuntary  dissolution,  liquidation or
         winding-up of the Company,

the Company shall mail to each holder of a Warrant a notice  specifying  (i) the
date or expected date on which any such record is to be taken for the purpose of
such  dividend,  distribution  or right,  and the amount and  character  of such
dividend, distribution or right, and (ii) the date or expected date on which any
such reorganization, reclassification,  recapitalization, consolidation, merger,
transfer, sale, disposition,  dissolution,  liquidation or winding-up is to take
place and the time, if any such time is to be fixed,  as of which the holders of
record of Common Stock (or Other Securities) shall be entitled to exchange their
shares  of  Common  Stock  (or Other  Securities)  for the  securities  or other
property    deliverable    upon    such    reorganization,     reclassification,
recapitalization,  consolidation,  merger, transfer, dissolution, liquidation or
winding-up.  Such  notice  shall be  mailed  at least 20 days  prior to the date
therein specified.

                  9. Registration of Common Stock. If any shares of Common Stock
required  to be reserved  for  purposes  of  exercise  of this  Warrant  require
registration with or approval of any governmental authority under any federal or
state law (other than the Securities Act and any State blue sky law) before such
shares may be issued upon  exercise,  the Company  shall,  at its expense and as
expeditiously as possible,  use its best efforts to cause such shares to be duly
registered or approved,  as the case may be. At any such time as Common Stock is
listed on any national  securities  exchange or trade market, the Company shall,
at its  expense,  obtain  promptly and maintain the approval for listing on each
such exchange or trade market,  upon official notice of issuance,  the shares of
Common Stock issuable upon exercise of the then  outstanding  Warrants;  and the
Company  shall also list on such national  securities  exchange or trade market,
shall  register  under the Exchange Act and shall  maintain such listing of, any
Other Securities that at any time are issuable upon exercise of the Warrants, if
and at the time that any  securities  of the same class  shall be listed on such
national securities exchange or trade market by the Company.

                  10.  Reservation of Stock, etc. The Company shall at all times
reserve and keep  available,  solely for issuance and delivery  upon exercise of
the Warrants,  the number of shares of Common Stock (or Other  Securities)  from
time to time issuable upon exercise of all Warrants at the time  outstanding and
otherwise in accordance with the terms of the Purchase Agreement.  All shares of
Common Stock (or Other Securities)  issuable upon exercise of any Warrants shall
be duly authorized and, when issued upon such exercise,  shall be validly issued
and, in the case of shares,  fully paid and  nonassessable  with no liability on
the part of the holders  thereof,  and, in the case of all securities,  shall be
free from all taxes, liens, security interests, encumbrances,  preemptive rights
and charges.  The transfer agent for the Common Stock,  which may be the Company
(the "Transfer  Agent"),  and every subsequent  Transfer Agent for any shares of
the Company's  capital  stock  issuable upon the exercise of any of the purchase
rights  represented  by this  Warrant,  are hereby  irrevocably  authorized  and
directed  at all times  until the  Expiration  Date to  reserve  such  number of
authorized  and unissued  shares as shall


                                       14

be requisite for such purpose.  The Company shall keep copies of this Warrant on
file with the  Transfer  Agent for the Common  Stock and with  every  subsequent
Transfer  Agent for any shares of the Company's  capital stock issuable upon the
exercise  of the rights of purchase  represented  by this  Warrant.  The Company
shall supply such Transfer Agent with duly executed stock  certificates for such
purpose.  All Warrant  Certificates  surrendered upon the exercise of the rights
thereby evidenced shall be canceled, and such canceled Warrants shall constitute
sufficient evidence of the number of shares of stock which have been issued upon
the exercise of such Warrants.  Subsequent to the Expiration  Date, no shares of
stock need be reserved in respect of any unexercised Warrant.

                  11.      Registration and Transfer of Warrants, etc.

                  11.1.  Warrant Register;  Ownership of Warrants.  Each Warrant
issued by the Company  shall be numbered  and shall be  registered  in a warrant
register (the "Warrant Register") as it is issued and transferred, which Warrant
Register  shall be maintained by the Company at its principal  office or, at the
Company's  election and expense,  by a Warrant Agent or the  Company's  transfer
agent.  The  Company  shall be entitled  to treat the  registered  Holder of any
Warrant on the Warrant  Register as the owner in fact  thereof for all  purposes
and shall not be bound to recognize  any equitable or other claim to or interest
in such  Warrant on the part of any other  Person,  and shall not be affected by
any notice to the  contrary,  except  that,  if and when any Warrant is properly
assigned in blank,  the Company  may (but shall not be  obligated  to) treat the
bearer  thereof as the owner of such  Warrant for all  purposes.  A Warrant,  if
properly assigned,  may be exercised by a new holder without a new Warrant first
having been issued.

                  11.2.  Transfer  of  Warrants.  This  Warrant  and all  rights
hereunder are  transferable  in whole or in part,  without  charge to the Holder
hereof,  upon  surrender  of  this  Warrant  with a  properly  executed  Form of
Assignment  attached hereto as Exhibit B at the principal  office of the Company
(or such other office or agency of the Company as it may in writing designate to
the Holder).  Upon any partial transfer,  the Company shall at its expense issue
and  deliver  to the  Holder a new  Warrant  of like  tenor,  in the name of the
Holder,  which shall be  exercisable  for such number of shares of Common  Stock
with respect to which rights under this Warrant were not so  transferred  and to
the transferee a new Warrant of like tenor, in the name of the transferee, which
shall be  exercisable  for such number of shares of Common Stock with respect to
which rights under this Warrant were so transferred.

                  11.3.  Replacement  of Warrants.  On receipt by the Company of
evidence reasonably satisfactory to the Company of the loss, theft,  destruction
or  mutilation  of this  Warrant  and,  in the case of any such  loss,  theft or
destruction of this Warrant,  on delivery of an indemnity  agreement  reasonably
satisfactory  in form and  amount  to the  Company  or,  in the case of any such
mutilation,  on surrender of such Warrant to the Company at its principal office
and cancellation  thereof, the Company at its expense shall execute and deliver,
in lieu thereof, a new Warrant of like tenor.

                  11.4.  Adjustments  To  Purchase  Price and  Number of Shares.
Notwithstanding any adjustment in the Purchase Price or in the number or kind of
shares of Common Stock


                                       15
<PAGE>

purchasable upon exercise of this Warrant, any Warrant theretofore or thereafter
issued  may  continue  to express  the same  number and kind of shares of Common
Stock as are stated in this Warrant, as initially issued.

                  11.5.   Fractional  Shares.   Notwithstanding  any  adjustment
pursuant  to Section 3 in the number of shares of Common  Stock  covered by this
Warrant  or any  other  provision  of this  Warrant,  the  Company  shall not be
required  to issue  fractions  of shares  upon  exercise  of this  Warrant or to
distribute  certificates which evidence fractional shares. In lieu of fractional
shares, the Company shall make payment to the Holder, at the time of exercise of
this  Warrant as herein  provided,  in an amount in cash equal to such  fraction
multiplied by the Current Market Price of a share of Common Stock on the date of
Warrant exercise.

                  12. Remedies;  Specific  Performance.  The Company  stipulates
that there would be no adequate  remedy at law to the Holder of this  Warrant in
the event of any default or threatened default by the Company in the performance
of or  compliance  with any of the terms of this  Warrant and  accordingly,  the
Company  agrees that, in addition to any other remedy to which the Holder may be
entitled  at law or in equity,  the Holder  shall be  entitled to seek to compel
specific  performance  of the  obligations  of the Company  under this  Warrant,
without the posting of any bond, in accordance  with the terms and conditions of
this  Warrant  in any court of the  United  States or any State  thereof  having
jurisdiction.  Except as  otherwise  provided by law, a delay or omission by the
Holder  hereto in exercising  any right or remedy  accruing upon any such breach
shall not impair the right or remedy or  constitute a waiver of or  acquiescence
in any such  breach.  No remedy  shall be  exclusive  of any other  remedy.  All
available remedies shall be cumulative.

                  13. No Rights or Liabilities as Shareholder. Nothing contained
in this  Warrant  shall be construed as  conferring  upon the Holder  hereof any
rights as a  stockholder  of the Company or as imposing  any  obligation  on the
Holder to purchase any  securities or as imposing any  liabilities on the Holder
as a stockholder  of the Company,  whether such  obligation or  liabilities  are
asserted by the Company or by creditors of the Company.

                  14.  Notices.   Any  notices,   consents,   waivers  or  other
communications  required or permitted to be given  hereunder  must be in writing

personally;  (ii) upon receipt,  when sent by facsimile,  (iii) three days after

amended,  modified,  supplemented  or  terminated,  and  waivers or  consents to

instrument  duly  executed  by the  party  against  which  enforcement  of  such
amendment,  modification,  supplement,  termination  or consent to  departure is
sought.

                  16.  Descriptive  Headings,  Etc. The headings in this Warrant
are for  convenience of reference  only and shall not limit or otherwise  affect
the  meaning  of terms  contained  herein.  Unless the  context of this  Warrant
otherwise  requires:  (1) words of any gender  shall be deemed to  include  each
other  gender;  (2) words using the singular or plural number shall also include
the  plural  or  singular  number,  respectively;  and (3) the  words  "hereof",

construed  in  accordance  with,  the laws of the State of  California  (without
giving effect to the conflict of laws principles thereof).

                  18. Registration Rights Agreement.  The shares of Common Stock
(and  Other  Securities)  issuable  upon  exercise  of  this  Warrant  (or  upon
conversion  of any  shares of Common  Stock  issued  upon such  exercise)  shall

Rights  Agreement).  Each holder of this Warrant shall be entitled to all of the
benefits  afforded  to a holder  of any such  Registrable  Securities  under the
Registration  Rights  Agreement  and  such  holder,  by its  acceptance  of this
