No. ___                                                              $250,000.00

      This  Debenture is issued by BSI2000,  INC., a Delaware  corporation  (the
"Company"),  to   ____________________________   (together  with  its  permitted
successors and assigns,  the "Holder")  pursuant to exemptions from registration
under the Securities Act of 1933, as amended.

                                   ARTICLE I.

      Section 1.01  PRINCIPAL AND  INTEREST.  For value  received,  on July ___,
2003,  the Company  hereby  promises to pay to the order of the Holder in lawful
money of the United  States of America and in  immediately  available  funds the
principal sum of Two Hundred Fifty Thousand Dollars (US $250,000), together with
interest on the unpaid  principal of this  Debenture at the rate of five percent
(5%) per year  (computed  on the basis of a  365-day  year and the  actual  days
elapsed)  from the date of this  Debenture  until paid. On the second (2nd) year
anniversary  from the date  hereof,  the  outstanding  principal  amount  of the
Debenture  and all accrued  interest,  to the extent not converted in accordance
with Section 1.02 hereof, shall be automatically converted into shares of Common
Stock (as defined below) at the Conversion Price (as defined below) set forth in
Section 1.02 hereof;  provided,  however,  that to the extent any such automatic
conversion  would  cause the  Holder  to own in excess of nine and 9/10  percent

<PAGE>

(9.9%) of the then  outstanding  Common  Stock of the  Company,  such  amount of
convertible  debenture and accrued  interest  shall not be converted and instead
shall be paid in cash to the Holder.

      Section 1.02 OPTIONAL CONVERSION.  The Holder is entitled,  at its option,
to convert,  and sell on the same day, at any time and from time to time,  until
payment in full of this  Debenture,  all or any part of the principal  amount of
the Debenture,  plus accrued interest,  into shares (the "Conversion Shares") of
the Company's common stock, par value $0.001 per share ("Common Stock"),  at the
price per share (the  "Conversion  Price")  equal to the lesser of (a) an amount
equal to one  hundred  twenty  percent  (120%) of the  closing  bid price of the
Common Stock as listed on a Principal Market (as defined  herein),  as quoted by
Bloomberg  L.P. (the  "Closing Bid Price") on the date hereof,  or (b) an amount
equal to eighty  percent  (80%) of the  lowest  Closing  Bid Price of the Common
Stock for the five (5) trading days  immediately  preceding the Conversion  Date
(as defined herein).  Subparagraphs (a) and (b) above are individually  referred
to as a "Conversion  Price". As used herein,  "Principal  Market" shall mean The
National  Association  of Securities  Dealers Inc.'s  Over-The-Counter  Bulletin
Board,  Nasdaq SmallCap Market, or American Stock Exchange.  If the Common Stock
is not traded on a Principal  Market,  the  Closing  Bid Price  shall mean,  the
reported  Closing Bid Price for the Common  Stock,  as furnished by the National
Association of Securities Dealers, Inc., for the applicable periods. No fraction
of  shares  or  scrip  representing  fractions  of  shares  will  be  issued  on
conversion,  but the number of shares  issuable  shall be rounded to the nearest
whole share. To convert this Debenture,  the Holder hereof shall deliver written
notice thereof, substantially in the form of Exhibit "A" to this Debenture, with
appropriate  insertions (the "Conversion Notice"), to the Company at its address
as set forth herein.  The date upon which the conversion shall be effective (the
"Conversion  Date")  shall be deemed to be the date set forth in the  Conversion
Notice.

      Section 1.03  RESERVATION  OF COMMON STOCK.  The Company shall reserve and
keep available out of its authorized but unissued shares of Common Stock, solely
for the purpose of effecting the  conversion of this  Debenture,  such number of
shares of Common Stock as shall from time to time be  sufficient  to effect such
conversion, based upon the Conversion Price. If at any time the Company does not
have a sufficient number of Conversion Shares authorized and available, then the
Company shall call and hold a special meeting of its stockholders  within [sixty
(60)]  days of that  time for the sole  purpose  of  increasing  the  number  of
authorized shares of Common Stock.

      Section 1.04 RIGHT OF REDEMPTION. The Company at its option shall have the
right  to  redeem,  with two (2)  business  days  advance  written  notice  (the
"Redemption Notice"), a portion or all outstanding  convertible  debenture.  The
redemption  price  shall be one  hundred  twenty  percent  (120%) of the  amount
redeemed plus accrued interest.

      Section 1.05 REGISTRATION RIGHTS. The Company is obligated to register the
resale of the  Conversion  Shares under the  Securities Act of 1933, as amended,
pursuant to the terms of a Registration  Rights  Agreement,  between the Company
and  the  Holder  of even  date  herewith  (the  "Investor  Registration  Rights
Agreement").

                                       2

      Section 1.06  INTEREST  PAYMENTS.  The interest so payable will be paid at
the time of maturity,  redemption or conversion to the person in whose name this
Debenture is registered.  At the time such interest is payable,  the Company, in
its sole  discretion,  may elect to pay  interest in cash (via wire  transfer or
certified  funds) or in the form of Common  Stock.  In the event of default,  as
described in Article III Section 3.01  hereunder,  the Holder may elect that the
interest be paid in cash (via wire  transfer or certified  funds) or in the form
of Common Stock. If paid in the form of Common Stock,  the amount of stock to be
issued  will be  calculated  as  follows:  the value of the  stock  shall be the
Closing Bid Price on: (i) the date the  interest  payment is due; or (ii) if the
interest  payment is not made when due, the date the interest payment is made. A
number of shares of Common  Stock with a value  equal to the amount of  interest
due shall be issued.  No  fractional  shares will be issued;  therefore,  in the
event  that the value of the  Common  Stock  per share  does not equal the total
interest due, the Company will pay the balance in cash.

      Section 1.07 PAYING AGENT AND REGISTRAR.  Initially,  the Company will act
as paying  agent and  registrar.  The  Company  may  change  any  paying  agent,
registrar,  or  Company-registrar  by giving  the  Holder not less than ten (10)
business  days' written  notice of its election to do so,  specifying  the name,
address, telephone number and facsimile number of the paying agent or registrar.
The Company may act in any such capacity.

                                  ARTICLE II.

      Section 2.01  AMENDMENTS  AND WAIVER OF DEFAULT.  The Debenture may not be
amended without the consent of the Holder.  Notwithstanding  the above,  without
the consent of the Holder,  the Debenture may be amended to cure any  ambiguity,
defect or inconsistency, to provide for assumption of the Company obligations to
the Holder,  or to make any change that does not adversely  affect the rights of
the Holder.

                                  ARTICLE III.

      Section 3.01 EVENTS OF DEFAULT. An Event of Default is defined as follows:

of the date of maturity of this Debenture;  (b) failure by the Company to comply
with the terms of the Irrevocable  Transfer Agent  Instructions  attached to the
Securities  Purchase  Agreement;  (c) failure by the Company's transfer agent to
issue Common Stock to the Holder  within ten (10) business days of the Company's
receipt of the attached  Notice of  Conversion  from Holder;  (d) failure by the
Company  for ten (10) days  after  notice to it to comply  with any of its other
agreements  in the  Debenture;  (e) events of bankruptcy  or  insolvency;  (f) a
breach by the Company of its obligations under the Securities Purchase Agreement
or the Investor  Registration Rights Agreement which is not cured by the Company
within ten (10) days after receipt of written notice thereof.

      Section 3.02 FAILURE TO ISSUE  UNRESTRICTED  COMMON STOCK. As indicated in
Article III Section 3.01, a breach by the Company of its  obligations  under the
Investor  Registration  Rights  Agreement  shall be deemed an Event of  Default,
which if not cured within ten (10) days, shall entitle the Holder to accelerated
full repayment of all debentures  outstanding and accrued interest thereon.  The
Company  acknowledges  that failure to honor a Notice of Conversion  shall cause
irreparable harm to the Holder.

                                       3

                                  ARTICLE IV.

in part, may be converted at any time following the date of closing, into shares

1.02 above.

      Section 4.02 RE-ISSUANCE OF DEBENTURE. When the Holder elects to convert a
part of the  Debenture,  then the Company  shall  reissue a new Debenture in the
same form as this Debenture to reflect the new principal amount.

      Section 4.03  TERMINATION  OF  CONVERSION  RIGHTS.  The Holder's  right to
convert the Debenture  into the Common Stock in accordance  with  paragraph 4.01
shall terminate on the date that is the second (2nd) year  anniversary  from the
date hereof and this Debenture shall be automatically  converted on that date in
accordance with the formula set forth in Section 4.01 hereof.

                                   ARTICLE V.

      Section  5.01  ANTI-DILUTION.  In the event that the Company  shall at any
time subdivide the  outstanding  shares of Common Stock,  or shall issue a stock
dividend  on the  outstanding  Common  Stock,  the  Conversion  Price in  effect
immediately  prior to such subdivision or the issuance of such dividend shall be
proportionately  decreased,  and in the event that the Company shall at any time
combine the outstanding  shares of Common Stock,  the Conversion Price in effect
immediately  prior  to such  combination  shall  be  proportionately  increased,
effective at the close of business on the date of such subdivision,  dividend or
combination as the case may be.

      Section  5.02  CONSENT  OF HOLDER TO SELL  CAPITAL  STOCK.  Except for the
Equity Line of Credit  Agreement  dated the date hereof  between the Company and
Cornell Capital Partners,  LP, so long as any of the principal of or interest on
this Note remains  unpaid and  unconverted,  the Company shall not,  without the
prior  consent of the Holder,  issue or sell (i) any Common  Stock or  Preferred
Stock without  consideration or for a consideration per share less than its fair
market value determined  immediately  prior to its issuance,  (ii) issue or sell

without  consideration  or for a  consideration  per share less than such Common
Stock's fair market value determined immediately prior to its issuance, or (iii)
file any registration statement on Form S-8.

      NOW, THEREFORE,  in consideration of the premises and the mutual covenants
contained  herein and other good and  valuable  consideration,  the  receipt and

         (c)  Failure  to  File  or  Obtain  Effectiveness  of the  Registration
Statement. In the event the Registration Statement is not filed by the Scheduled
Filing  Deadline  or is not  declared  effective  by the  SEC on or  before  the
Scheduled  Effective Deadline,  or if after the Registration  Statement has been
declared effective by the SEC, sales cannot be made pursuant to the Registration
Statement  (whether  because  of a failure  to keep the  Registration  Statement
effective,  failure to disclose such information as is necessary for sales to be
made  pursuant to the  Registration  Statement,  failure to register  sufficient
shares of Common Stock or otherwise),  then as partial relief for the damages to
any holder of Registrable Securities by reason of any such delay in or reduction
of its ability to sell the underlying shares of Common Stock (which remedy shall
not be  exclusive of any other  remedies at law or in equity),  the Company will
pay as  liquidated  damages (the  "Liquidated  Damages")  to the holder,  at the
holder's  option,  either a cash amount or shares of the Company's  Common Stock
within three (3) business  days,  after demand  therefore,  equal to two percent
(2%) of the  liquidated  value  of the  Convertible  Debentures  outstanding  as
Liquidated  Damages for each thirty (30) day period after the  Scheduled  Filing
Deadline or the Scheduled Effective Date as the case may be. If paid in the form

                                      -2-
<PAGE>

of Common Stock, the amount of stock to be issued will be calculated as follows:
the value of the stock shall be the Closing Bid Price on the date the liquidated
damages payment is demanded.

         (d) Liquidated Damages. The Company and the Investor hereto acknowledge
and agree that the sums payable  under  subsection  2(c) above shall  constitute
liquidated damages and not penalties.  The parties further  acknowledge that (i)
the amount of loss or damages likely to be incurred is incapable or is difficult
to precisely  estimate,  (ii) the amounts  specified in such  subsections bear a
reasonable  relationship to, and are not plainly or grossly  disproportionate to
the probable  loss likely to be incurred in  connection  with any failure by the
Company to obtain or maintain the  effectiveness  of a  Registration  Statement,
(iii) one of the reasons for the Company and the Investor  reaching an agreement
as to such amounts was the  uncertainty  and cost of  litigation  regarding  the
question  of  actual  damages,  and  (iv)  the  Company  and  the  Investor  are
sophisticated  business parties and have been  represented by sophisticated  and
able legal counsel and negotiated this Agreement at arm's length.

         3. RELATED OBLIGATIONS.

         (a)  The  Company  shall  keep  the  Registration  Statement  effective
pursuant  to Rule 415 at all times  until the date on which the  Investor  shall
have sold all the Registrable  Securities covered by such Registration Statement
(the  "Registration  Period"),   which  Registration  Statement  (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.

         (b) The Company  shall  prepare  and file with the SEC such  amendments
(including   post-effective   amendments)  and  supplements  to  a  Registration
Statement  and  the  prospectus  used  in  connection  with  such   Registration
Statement,  which  prospectus  is to be filed  pursuant to Rule 424  promulgated
under the 1933 Act,  as may be  necessary  to keep such  Registration  Statement
effective at all times during the Registration  Period, 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 such Registration Statement
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 such  Registration  Statement.  In the case of
amendments and supplements to a Registration  Statement which are required to be
filed  pursuant to this Agreement  (including  pursuant to this Section 3(b)) by
reason of the Company's filing a report on Form 10-KSB,  Form 10-QSB or Form 8-K
or any analogous  report under the  Securities  Exchange Act of 1934, as amended
(the "1934 Act"),  the Company shall  incorporate  such report by reference into
the  Registration  Statement,  if applicable,  or shall file such  amendments or
supplements  with the SEC on the same day on which the 1934 Act  report is filed
which  created  the  requirement  for the  Company  to amend or  supplement  the
Registration Statement.

                                      -3-
<PAGE>

         (c) The  Company  shall  furnish  to each  Investor  whose  Registrable
Securities are included in any Registration  Statement,  without charge,  (i) at
least one (1) copy of such Registration  Statement as declared  effective by the
SEC and any amendment(s) thereto,  including financial statements and schedules,
all  documents  incorporated  therein  by  reference,   all  exhibits  and  each
preliminary prospectus, (ii) ten (10) copies of the final 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 as such  Investor may  reasonably  request from time to time in
order to facilitate the disposition of the Registrable  Securities owned by such
Investor.

         (d) The Company  shall use its best efforts to (i) register and qualify
the Registrable  Securities covered by a Registration Statement 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 (w) make any
change to its  certificate  of  incorporation  or  by-laws,  (x)  qualify  to do
business in any jurisdiction where it would not otherwise be required to qualify
but for this Section 3(d),  (y) subject  itself to general  taxation in any such
jurisdiction,  or (z) file a general  consent  to service of process in any such
jurisdiction.  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 threat of any proceeding for such purpose.

         (e) As promptly as  practicable  after  becoming aware of such event or
development,  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  (provided that in no event shall such notice contain any
material, nonpublic information), and promptly prepare a supplement or amendment
to such Registration Statement to correct such untrue statement or omission, and
deliver ten (10) copies of such  supplement or amendment to each  Investor.  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),  (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.

                                      -4-
<PAGE>

         (f) 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  within the United  States of America  and, if such an
order or  suspension  is  issued,  to obtain  the  withdrawal  of such  order or
suspension at the earliest possible moment and to notify each Investor who holds
Registrable  Securities  being  sold  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.

         (g) At the  reasonable  request  of any  Investor,  the  Company  shall
furnish to such Investor,  on the date of the  effectiveness of the Registration
Statement  and  thereafter  from time to time on such dates as an  Investor  may
reasonably request (i) 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,  and  (ii) an  opinion,  dated  as of such  date,  of  counsel
representing the Company for purposes of such Registration  Statement,  in form,
scope and substance as is customarily given in an underwritten  public offering,
addressed to the Investors.

         (h) The Company shall make available for inspection by (i) any Investor
and (ii) one (1) firm of accountants  or other agents  retained by the Investors
(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, and cause
the Company's officers,  directors and employees to supply all information which
any Inspector may reasonably  request;  provided,  however,  that each Inspector
shall agree, and each Investor hereby agrees,  to hold in strict  confidence and
shall not make any disclosure (except to an Investor) or use 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 or any other  agreement of which
the  Inspector  and the Investor has  knowledge.  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.

         (i) 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  Agreement 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

                                      -5-
<PAGE>

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.

         (j) The  Company  shall  use its best  efforts  either to cause all the
Registrable  Securities covered by a Registration  Statement (i) 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  exchange  or (ii) the
inclusion for quotation on the National Association of Securities Dealers,  Inc.
OTC Bulletin Board for such  Registrable  Securities.  The Company shall pay all
fees and  expenses in  connection  with  satisfying  its  obligation  under this
Section 3(j).

         (k) The Company shall cooperate with the Investors who hold Registrable
Securities being offered and, to the extent applicable, 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 Investors may  reasonably  request and  registered in
such names as the Investors may request.

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

         (m) The Company shall make generally  available to its security holders
as soon as practical, but not later than ninety (90) days after the close of the
period  covered  thereby,  an earnings  statement  (in form  complying  with the
provisions  of Rule 158 under the 1933 Act)  covering a twelve (12) month period
beginning  not later than the first day of the  Company's  fiscal  quarter  next
following the effective date of the Registration Statement.

         (n) 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.

         (o) Within two (2) business days after a Registration  Statement  which
covers  Registrable  Securities  is declared  effective  by the SEC, the Company
shall deliver,  and shall cause legal counsel for the Company to deliver, to the
transfer  agent for such  Registrable  Securities  (with copies to the Investors
whose  Registrable  Securities  are  included  in such  Registration  Statement)
confirmation that such Registration Statement has been declared effective by the
SEC in the form attached hereto as Exhibit A.

         (p) 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.

         4. OBLIGATIONS OF THE INVESTORS.

      Each Investor  agrees that, upon receipt of any notice from the Company of
the  happening  of any event of the kind  described in Section 3(f) or the first
sentence of 3(e),  such Investor will  immediately  discontinue  disposition  of
Registrable  Securities pursuant to any 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(e) or receipt of
notice that no supplement or amendment is required.  Notwithstanding anything to
the contrary,  the Company shall cause its transfer agent to deliver  unlegended
certificates  for  shares of Common  Stock to a  transferee  of an  Investor  in
accordance  with the terms of the  Securities  Purchase  Agreement in connection
with any sale of  Registrable  Securities  with respect to which an Investor has
entered  into a contract  for sale prior to the  Investor's  receipt of a notice
from the Company of the happening of any event of the kind  described in Section
3(f) or the  first  sentence  of 3(e) and for  which  the  Investor  has not yet
settled.

         5. EXPENSES OF REGISTRATION.

      All  expenses  incurred  in  connection  with  registrations,  filings  or
qualifications pursuant to Sections 2 and 3, including,  without limitation, all
registration,  listing and qualifications fees,  printers,  legal and accounting
fees shall be paid by the Company.

         6. INDEMNIFICATION.

      With  respect  to   Registrable   Securities   which  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,  the directors,
officers, partners,  employees, agents,  representatives of, and each Person, if
any, who  controls  any Investor  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, reasonable 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  ("Blue Sky  Filing"),  or the  omission or alleged  omission to state a
material fact required to be stated  therein or necessary to make the statements
therein not misleading; (ii) any untrue statement or alleged untrue statement of
a material fact contained in any 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

                                      -7-
<PAGE>

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  there  under  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"). The Company shall
reimburse  the  Investors  and each such  controlling  person  promptly  as such
expenses  are  incurred  and  are  due  and  payable,  for  any  legal  fees  or
disbursements 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):  (x) shall not apply to a Claim by an  Indemnified  Person 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 such Indemnified Person
expressly  for  use in  connection  with  the  preparation  of the  Registration
Statement or any such amendment thereof or supplement thereto;  (y) shall not be
available  to the extent  such Claim is based on a failure  of the  Investor  to
deliver  or to  cause to be  delivered  the  prospectus  made  available  by the
Company, if such prospectus was timely made available by the Company pursuant to
Section 3(c); and (z) 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 hereof.

         (b) In connection with a Registration  Statement,  each 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, each of its officers,  employees,  representatives,  or agents
and each Person, if any, who controls the Company within the meaning of the 1933
Act or the  1934  Act  (each  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 is 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 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 net 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  prospectus  shall
not inure to the benefit of any  Indemnified  Party if the untrue  statement  or
omission of material fact contained in the prospectus was corrected and such new
prospectus  was delivered to each Investor  prior to such  Investor's use of the
prospectus to which the Claim relates.

                                      -8-
<PAGE>

         (c) 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 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  an
Indemnified  Person or Indemnified  Party shall have the right to retain its own
counsel  with the fees and  expenses  of not more than one (1)  counsel for such
Indemnified  Person or Indemnified  Party to be paid by the indemnifying  party,
if, in the reasonable opinion of counsel retained by the indemnifying party, 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 and any
other party  represented  by such counsel in such  proceeding.  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
indemnifying  party shall be liable for any  settlement of any action,  claim or
proceeding effected without its prior written consent;  provided,  however, that
the indemnifying party shall not unreasonably  withhold,  delay or condition its
consent.  No indemnifying party shall,  without the prior written 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.

         (d) The  indemnification  required  by this  Section 6 shall be made by
periodic  payments of the amount thereof during the course of the  investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

         (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.

                                      -9-

         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 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 (ii) contribution 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 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 to:

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

         (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 as are required by 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

         9. ASSIGNMENT OF REGISTRATION RIGHTS.

      The rights under this Agreement shall not be assignable by the Investor.

         10. AMENDMENT OF REGISTRATION RIGHTS.

      Provisions of this Agreement may be amended and the observance thereof may
be waived (either generally or in a particular instance and either retroactively
or  prospectively),  only with the written  consent of the Company and Investors
who then  hold at least  two-thirds  (2/3) of the  Registrable  Securities.  Any
amendment or waiver effected in accordance with this Section 10 shall be binding
upon each Investor and the Company.  No such amendment shall be effective to the
extent  that it  applies to fewer  than all of the  holders  of the  Registrable
Securities.  No consideration shall be offered or paid to any Person to amend or

                                      -10-

consent to a waiver or  modification  of any provision of any of this  Agreement
unless the same  consideration  also is  offered  to all of the  parties to this
Agreement.

agrees not to assert in any suit, action or proceeding, any claim that it is not

suit,  action or proceeding is improper.  Each party hereby  irrevocably  waives
personal  service of process and  consents to process  being  served in any such
suit,  action or  proceeding  by  mailing a copy  thereof  to such  party at the
address for such notices to it under this Agreement and agrees that such service
shall  constitute  good and  sufficient  service of process and notice  thereof.
Nothing  contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law. 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.
EACH PARTY HEREBY  IRREVOCABLY  WAIVES ANY RIGHT IT MAY HAVE,  AND AGREES NOT TO
REQUEST,  A JURY  TRIAL FOR THE  ADJUDICATION  OF ANY  DISPUTE  HEREUNDER  OR IN

the other party hereto by  facsimile  transmission  of a copy of this  Agreement
bearing the signature of the party so delivering this Agreement.

         (h) Each party shall do and perform, or cause to be done and performed,

                         FORM OF NOTICE OF EFFECTIVENESS
                            OF REGISTRATION STATEMENT

         Re:  BSI2000, INC.

Ladies and Gentlemen:

      We are counsel to BSI2000,  Inc., a Delaware  corporation (the "Company"),
and have  represented  the Company in  connection  with that certain  Securities
Purchase  Agreement  (the  "Securities  Purchase  Agreement"),  and that certain
Equity Line of Credit Agreement (the "Equity Line of Credit Agreement"), entered
into by and among the Company and the investors named therein (collectively, the
"Investors") pursuant to which the Company issued to the Investors shares of its
Common Stock,  par value $0.01 per share (the "Common  Stock").  Pursuant to the
Securities  Purchase  Agreement  and the Equity  Line of Credit  Agreement,  the
Company also has entered into a Registration Rights Agreement with the Investors
(the "Investor  Registration  Rights  Agreement")  pursuant to which the Company
agreed,  among other things, to register the Registrable  Securities (as defined
in the  Registration  Rights  Agreement)  under the  Securities  Act of 1933, as
amended (the "1933 Act"). In connection with the Company's obligations under the
Registration  Rights  Agreement,  on  ____________  ____,  the  Company  filed a
Registration  Statement  on Form  ________  (File  No.  333-_____________)  (the
"Registration  Statement")  with the  Securities  and  Exchange  SEC (the "SEC")
relating to the  Registrable  Securities  which names each of the Investors as a
selling stockholder there under.

      In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by  telephone  that the SEC has entered an order  declaring
the  Registration  Statement  effective  under  the 1933 Act at  [ENTER  TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,  after
telephonic  inquiry  of a  member  of the  SEC's  staff,  that  any  stop  order
suspending its  effectiveness  has been issued or that any  proceedings for that
purpose  are  pending  before,  or  threatened  by, the SEC and the  Registrable
Securities  are  available  for  resale  under  the  1933  Act  pursuant  to the
Registration Statement.

                                           Very truly yours,

                                           KIRKPATRICK & LOCKHART LLP

                                           By:
