     tranche being exercisable at $1.58 per share through August 18, 2000.

         In addition, the Company announced the completion of a previously

                  NONTRANSFERABLE COMMON STOCK PURCHASE WARRANT

1. ISSUANCE. In consideration of good and valuable consideration, the receipt of
which is hereby  acknowledged by StarBase  Corporation,  a Delaware  corporation
(the "Company") _________________ or registered assigns (the "Holder") is hereby
granted the right to  purchase at any time until 5:00 P.M.,  New York City time,
on August  18,  2000  (the  "Expiration  Date"),  (___________)  fully  paid and
nonassessable  shares of the Company's  Common  Stock,  par value $.01 per share
(the  "Common  Stock")  at an  initial  exercise  price of $1.58 per share  (the
"Exercise  Price"),  subject  to  further  adjustment  as set forth in Section 6
hereof.

2. EXERCISE OF WARRANTS.  This Warrant is exercisable in whole or in part at the
Exercise Price per share of Common Stock payable  hereunder,  payable in cash or
by certified or official bank check. Upon surrender of this Warrant  Certificate
with the annexed Notice of Exercise Form duly executed, together with payment of
the Exercise Price for the shares of Common Stock purchased, the Holder shall be
entitled to receive a certificate or certificates for the shares of Common Stock
so purchased.

3. RESERVATION OF SHARES. The Company hereby agrees that at all times during the
term of this Warrant  there shall be reserved for issuance upon exercise of this
Warrant  such  number of shares of its  Common  Stock as shall be  required  for
issuance upon exercise of this Warrant (the "Warrant Shares").

4.  MUTILATION  OR LOSS OF  WARRANT.  Upon  receipt by the  Company of  evidence
satisfactory  to it of the  loss,  theft,  destruction  or  mutilation  of  this
Warrant,  and (in the case of loss, theft or destruction)  receipt of reasonably
satisfactory indemnification, and (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will execute and deliver a new Warrant
of like tenor and date and any such lost, stolen, destroyed or mutilated Warrant

6. PROTECTION AGAINST DILUTION.

(1)  ADJUSTMENT  MECHANISM.  If an adjustment of the Exercise  Price is required
pursuant to this Section 6, the Holder shall be entitled to purchase such number
of  additional  shares of  Common  stock as will  cause (I) the total  number of
shares of Common Stock Holder is entitled to purchase  pursuant to this Warrant,
multiplied  by (ii) the adjusted  purchase  price per share,  to equal (iii) the
dollar  amount of the total  number of shares of Common Stock Holder is entitled
to purchase  before  adjustment  multiplied by the total  purchase  price before
adjustment.

(2)  CAPITAL  ADJUSTMENTS.  In case of any stock split or reverse  stock  split,
stock dividend,  reclassification of the Common Stock, recapitalization,  merger
or consolidation,  or like capital adjustment  affecting the Common Stock of the
Company,  the  provisions  of this Section 6 shall be applied as if such capital
adjustment event had occurred  immediately prior to the date of this Warrant and
the original  purchase  price had been fairly  allocated to the stock  resulting
from such  capital  adjustment;  and in other  respects the  provisions  of this
Section  shall be applied in a fair,  equitable and  reasonable  manner so as to
give effect,  as nearly as may be, to the purposes  hereof. A rights offering to
stockholders  shall be deemed a stock  dividend  to the  extent  of the  bargain
purchase element of the rights.

Debenture be overdue, and neither the Company nor any such agent shall be 
affected by notice to the contrary.

                  4. A.  Subject to Sections 4B and 4C, the Holder of this
Debenture is entitled, at its option,  to convert at any time commencing the
earlier of (a) ninety (90) days after the Issuance Date, or (b) at the option of
the Company, at any time after the effective date of the  Registration Statement
filed pursuant to the Registration  Rights  Agreement  between  the  Company and
the  Holder,  or the Holder's  predecessor  in  interest,  the  principal amount
of this  Debenture, provided that the principal amount is at least US $10,000 
(unless if at the time of such election to convert the  aggregate  principal 
amount of all  Debentures registered to the Holder is less that Ten Thousand
Dollars (US  $10,000),  then the whole  amount  thereof)  into  shares of Common
Stock of the Company  at a conversion price for each share of Common Stock equal
to the lesser of (a) 100% of the Market Price on the Issuance Date, and (b) (i)
84% of the Market Price on the  Conversion  Date if such date is between ninety 
(90) and one hundred twenty (120) days from the date  hereof;  (ii) 80% of the 
Market Price if the date is between one hundred twenty-one (121) and one hundred
fifty (150) days from the date hereof, or (iii) 78% of the Market Price 
thereafter.  For purposes of this Section 4, the Market Price shall be the
average closing bid price of the Common Stock on the five (5) trading days  
immediately preceding the Issuance Date or Conversion Date, as may be
applicable,  as reported by the National  Association of Securities Dealers, or
the closing bid price on the  over-the-counter  market on such date or, in the
event the  Common  Stock is listed on a stock  exchange, the Market  Price shal
be the closing  price on the  exchange on such date,  as reported  in the  Wall 
Street  Journal.  Conversion  shall  be  effectuated  by surrendering  the  
Debentures  to be  converted  to the Company with the form of conversion  notice
attached hereto as Exhibit A, executed by the Holder of the Debenture evidencing
such  Holder's  intention to convert this  Debenture or aspecified  portion (as 
above provided) hereof,  and accompanied,  if required by the Company, by proper
assignment hereof in blank.  Interest accrued or accruing from the date of
issuance to the date of conversion  shall, at the option of the Company, be paid
in cash or Common Stock upon conversion at the Conversion Rate.  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.  
The date on which notice of conversion  is given (the  "Conversion 

                                       10

Date")  shall be deemed to be the date on which the  Holder has  delivered  this
Debenture, with the conversion notice duly executed, to the Company or, the date
set  forth  in such  facsimile  delivery  of the  notice  of  conversion  if the
Debenture is received by the Company  within three (3) business days  therefrom.
Facsimile  delivery of the conversion notice shall be accepted by the Company at
telephone number (714-442-4404);  ATTN: Doug Norman).  Certificates representing
Common Stock upon  conversion  will be delivered  within three (3) business days
from the date the notice of conversion with the original  Debenture is delivered
to the Company.


                  B.       The  Company  shall  have the  right to  require,  by
                           written  notice to the  Holder of this  Debenture  at
                           least ten (10) days prior to the Maturity Date,  that
                           the Holder of this  Debenture  exercise  its right of
                           conversion with respect to all or that portion of the
                           principal  amount  and  interest  outstanding  on the
                           Maturity Date.

                  C.       In lieu of converting into Common Stock,  the Company
                           will have the  option of  partially  or fully  paying
                           cash to the  Holder so that the Holder  will  realize
                           the full  economic  benefit the Holder  would  derive
                           from converting the Debentures and selling the Common
                           Stock at the closing ask price on the Conversion Date
                           with no  transaction  fees.  The  Company  agrees  to
                           notify the Holder,  in writing,  at least ten trading
                           days in  advance  of any  time  period  in  which  it
                           intends to exercise this option.

                  5. The  Company  may at its option  redeem all or a portion of
the outstanding Debentures upon ten (10) days written or telecopy  notice to the
Holder. If the Company fails to redeem the Debentures at the end of such ten-da
period,  the Company  shall promptly pay the  Holder by wire  transfer a penalty
equal to $100,000 and shall be precluded from redeeming any outstanding
Debentures at any time  thereafter.  Time is of the essence  as to the Company's
payment of the penalty for failure to redeem.

                  6. No provision of this  Debenture  shall alter or impair the
obligation of the Company,  which is absolute  and  unconditional,  to pay the
principal  of, and interest on, this  Debenture at the time,  place,  and rate, 
and in the coin or currency,  herein  prescribed.  This  Debenture and all other
Debentures now or hereafter issued of similar terms are direct obligations of 
the Company.

                  7. No recourse  shall be had for the payment of the  principal
of, or the  interest  on,  this  Debenture,  or for any claim based  hereon,  or
otherwise in respect hereof, against any incorporator,  shareholder,  officer or
director,  as such,  past,  present or future,  of the Company or any  successor
corporation,  whether by virtue of any constitution,  statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance  hereof and as part of the  consideration for the issue
hereof, expressly waived and released.

                  8.  If  the  Company  merges  or  consolidates   with  another
corporation  or sells or  transfers  all or  substantially  all of its assets to
another  person  and the  holders of the Common  Stock are  entitled  to receive
stock,  securities  or property in respect of or in exchange  for Common  Stock,
then as a condition of such merger, consolidation, sale or transfer, the Company
and any such  successor,  purchaser or  transferee  agree that the Debenture may
thereafter  be  converted on the terms and subject to the  conditions  set forth
above into the kind and amount of stock,  securities or property receivable upon
such merger, consolidation, sale or transfer by a holder of the number of shares
of Common Stock into which this Debenture might have been converted  immediately
before such  merger,  consolidation,  sale or transfer,  subject to  adjustments
which shall be as nearly  equivalent as may be practicable.  In the event of any
proposed merger,  consolidation or sale or transfer of all or substantially  all
of the assets of the Company (a "Sale"),  the Holder hereof shall have the right
to convert by delivering a Notice of Conversion  to the Company  within  fifteen
(15) days of receipt of notice of such Sale from the  Company.  In the event the
Holder hereof shall elect not to convert, the Company may prepay all outstanding

                                       11

                                      
<PAGE>


principal and accrued  interest on this Debenture,  less all amounts required by
law to be deducted,  upon which  tender of payment  following  such notice,  the
right of conversion shall terminate.

                  9. The Holder of the Debenture,  by acceptance hereof,  agrees
that this  Debenture is being  acquired for investment and that such Holder will
not offer,  sell or otherwise  dispose of this Debenture or the shares of Common
Stock issuable upon conversion thereof except under circumstances which will not
result in a  violation  of the Act or any  applicable  state Blue Sky or foreign
laws or similar laws relating to the sale of securities.

                  10.  This  Debenture  shall be governed  by and  construed  in
accordance with the laws of the State of New York. Each of the parties  consents
to the jurisdiction of the federal courts whose districts  encompass any part of
the City of New York or the state courts of the State of New York sitting in the
City of New York in connection with any dispute arising under this Agreement and
hereby waives, to the maximum extent permitted by law, any objection,  including
any  objection  based  ON  FORUM  NON  COVENIENS,  to the  bringing  of any such
proceeding in such jurisdictions.

                  11.  The following shall constitute an "Event of Default":


                           a.      The Company  shall  default in the payment of
                                   principal or interest on this  Debenture  and
                                   such default shall remain unremedied for five
                                   (5) business  days after the Company has been
                                   notified  of  the  default  in  writing  by a
                                   Holder; or

                           b.      Any of the representations or warranties made
                                   by the  Company  herein,  in  the  Securities
                                   Purchase Agreement,  or in any certificate or
                                   financial   or   other   written   statements
                                   furnished by the Company in  connection  with
                                   the execution and delivery of this  Debenture
                                   or the Securities Purchase Agreement shall be
                                   false or misleading  in any material  respect
                                   at the time made; or

                           c.      The Company  fails to issue shares of Common
                                   Stock to the Holder or to cause its Transfer
                                   Agent to issue shares of Common Stock upon
                                   exercise by the Holder of the  conversion 
                                   rights of the  Holder in  accordance with the
                                   terms of this Debenture, fails to transfer or
                                   to cause its Transfer Agent to transfer any 
                                   certificate for shares of Common Stock issued
                                   to the  Holder  upon  conversion  of this 
                                   Debenture and when required by this Debenture
                                   or the Registration  Rights  Agreement,  or
                                   fails to remove any restrictive  legend or to
                                   cause its Transfer Agent to transfer on any 
                                   certificate or any shares of Common Stock 
                                   issued to the Holder upon  conversion of this
                                   Debenture as and when required by this 
                                   Debenture,  the Securities Purchase Agreement

                                   such failure shall continue uncured for five
                                   (5) business  days after the Company has been

                                   Holder.

the Holder and in the Holder's  sole  discretion,  the Holder may consider  this
Debenture immediately due and payable,  without presentment,  demand, protest or
notice of any kinds, all of which are hereby expressly  waived,  anything herein
or in any note or other instruments  contained to the contrary  notwithstanding,
and the Holder may  immediately  enforce any and all of the Holder's  rights and
remedies provided herein or any other rights or remedies afforded by law.

                 12. Nothing  contained in this Debenture  shall be construed as

shareholders  or any rights  whatsoever as a shareholder of the Company,  unless
and to the extent converted in accordance with the terms hereof.

<PAGE>


                  I.       REGISTRATION.

(a)  Mandatory Registration. The Company shall prepare and file with the SEC, no
     later than thirty (30) days  following  the initial  Closing Date under the
     Securities Purchase Agreement,  either a Registration Statement on Form S-3
     registering  for resale by the  Investor a  sufficient  number of shares of
     Common  Stock for the Initial  Investors  (or such lesser  number as may be
     required  by the SEC,  but in no event less than the number of shares  into
     which the Debentures  would be convertible and the Warrants  exercisable at
     the time of filing of the Form S-3, or an amendment to any pending  Company
     Registration  Statement  on Form S-3,  and such  Registration  Statement or
     amended  Registration  Statement  shall state that, in accordance with Rule
     416 and 457 under the  Securities  Act, it also  covers such  indeterminate
     number of  additional  shares of Common Stock as may become  issuable  upon
     conversion  of the  Debentures  and the exercise of the Warrants  resulting
     from adjustment in the Conversion  Price, or to prevent dilution  resulting
     from stock splits, or stock dividends),  which Registration Statement shall
     be declared  effective no later than 90 days after the Closing  Date. If at
     any time the number of shares of Common Stock into which the Debentures may
     be converted  exceeds the  aggregate  number of shares of Common Stock then
     registered,  the Company shall, within ten (10) business days after receipt
     of a written  notice from any Investor,  either (i) amend the  Registration
     Statement filed by the Company pursuant to the preceding sentence,  if such
     Registration  Statement has not been declared  effective by the SEC at that
     time, to register all shares of Common Stock into which the  Debentures may
     be  converted,  or (ii) if such  Registration  Statement  has been declared
     effective  by the  SEC at  that  time,  file  with  the  SEC an  additional
     Registration  Statement  on Form S-3 to register the shares of Common Stock
     into which the Debentures may be converted that exceed the aggregate number
     of shares of Common Stock already registered.

                  (b)   Payments by the Company.
                          If the Registration Statement covering the Registrable
Securities  required to be filed by the Company  pursuant to Section 2(a) hereof
is not  effective by ninety (90) days  following  the initial  Closing Date (the
"Required  Effective  Date") (except as provided by the last sentence of section
2a), then the Company will make payments to the Initial Investor in such amounts
and at such times as shall be  determined  pursuant to this  Section  2(b).  The
amount to be paid by the Company to the Initial  Investor shall be determined as
of each Computation  Date, and such amount shall be equal to one (1%) percent of
the  purchase  price  paid  by the  Initial  Investor  for all  Debentures  then
purchased and outstanding  pursuant to the Securities Purchase Agreement for any
period from the Required  Effective Date to the first Computation Date, two (2%)
percent to the next  Computation Date and three (3%) percent to each Computation
Date thereafter,  until the Registration  Statement is declared effective by the
SEC (the  "Periodic  Amount").  The full  Periodic  Amount  shall be paid by the
Company in  immediately  available  funds within three  business days after each
Computation  Date.  Notwithstanding  the foregoing,  the amounts  payable by the
Company  pursuant to this provision shall not be payable to the extent any delay
in the effectiveness of the Registration  Statement occurs because of an act of,
or a failure to act or to act timely by the  Initial  Investor or its counsel or
the SEC, or in the event all of the Registrable  Securities may be sold pursuant
to Rule 144 or another available exemption under the Act.

                  As used in this Section 2(b),  the following  terms shall have
the following meanings:

                  "Computation  Date"  means the date which is thirty  (30) days
after the Required  Effective  Date (except as provided by the last  sentence of
section 2(a)),  and, if the Registration  Statement  required to be filed by the
Company pursuant to Section 2(a) has not theretofore been declared  effective by
the SEC, each date which is thirty (30) days after the previous Computation Date
(pro rated for partial periods) until such Registration Statement is so declared
effective.

         3.       OBLIGATIONS OF THE COMPANY.  In connection with the 
registration of the Registrable Securities, the Company shall do each of the
following.

                                       17
<PAGE>



                  (a)  Prepare  promptly  and file with the SEC, a  Registration
Statement  with  respect to not less than the number of  Registrable  Securities
provided in Section 2(a),  above, and thereafter use its reasonable best efforts
to cause each  Registration  Statement  relating to  Registrable  Securities  to
become  effective  ninety  (90)  days  after  the  Closing  Date,  and  keep the
Registration   Statement   effective  at  all  times  until  the  earliest  (the
"Registration  Period") of (i) the date that is two years after the Closing Date
(ii) the date when the Investors may sell all Registrable  Securities under Rule
144 or  (iii)  the date  the  Investors  no  longer  own any of the  Registrable
Securities,   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) Prepare and file with the SEC such  amendments  (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus  used  in  connection  with  the  Registration  Statement  as  may be
necessary  to  keep  the   Registration   effective  at  all  times  during  the
Registration  Period,  and,  during the  Registration  Period,  comply  with the
provisions  of  the  Securities  Act  with  respect  to the  disposition  of all
Registrable  Securities  of the Company  covered by the  Registration  Statement
until such time as all of such  Registrable  Securities 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;

                  (c)  The  Company  shall  permit  a  single  firm  of  counsel
designated by the Initial Investors to review the Registration Statement and all
amendments and  supplements  thereto a reasonable  period of time prior to their
filing with the SEC.

                  (d) Furnish to each Investor whose Registrable  Securities are
included in the Registration  Statement and its legal counsel  identified to the
Company, (i) promptly after the same is prepared and publicly distributed, filed
with the SEC,  or  received  by the  Company,  one (1) copy of the  Registration
Statement,  each  preliminary  prospectus and prospectus,  and each amendment or
supplement  thereto,  and (ii) such  number of copies of a  prospectus,  and all
amendments and supplements  thereto and such other  documents,  as such Investor
may reasonably request in order to facilitate the disposition of the Registrable
Securities owned by such Investor;

                  (e) As promptly as  practicable  after  becoming aware of such
event,  notify each  Investor of the happening of any event of which the Company
has knowledge,  as a result of which the prospectus included in the Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits 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 use its best efforts promptly to prepare a supplement
or amendment to the Registration  Statement or other appropriate filing with the
SEC to correct such untrue statement or omission, and deliver a number of copies
of such supplement or amendment to each Investor as such Investor may reasonably
request;

                  (f) As promptly as  practicable  after  becoming aware of such
event, notify each Investor who holds Registrable  Securities being sold (or, in
the  event  of an  underwritten  offering,  the  managing  underwriters)  of the
issuance by the SEC of a Notice of  Effectiveness or any notice of effectiveness
or any stop order or other  suspension of the  effectiveness of the Registration
Statement at the earliest possible time;

                  (g) Use its  reasonable  efforts to secure  designation of all
the Registrable  Securities covered by the Registration  Statement as a National
Association of Securities Dealers Automated  Quotations System ("NASDAQ") "Small
Capitalization"  within  the  meaning  of  Rule  11Aa2-1  of the SEC  under  the
Securities  Exchange  Act of 1934,  as amended  (the  "Exchange  Act"),  and the
quotation of the Registrable  Securities on the NASDAQ SmallCap  Market;  or if,
despite the Company's  reasonable  efforts to satisfy the preceding clause,  the
Company  is  unsuccessful  in doing  so,  to secure  NASDAQ/OTC  Bulletin  Board
authorization  and  quotation  for  such  Registrable  Securities  and,  without
limiting the  generality  of the  foregoing,  to arrange for at least two market
makers to register with the National  Association  of Securities  Dealers,  Inc.
("NASD") as such with respect to such Registrable Securities;

                                       18

<PAGE>


                  (h)  Provide a transfer  agent and  registrar,  which may be a
single entity, for the Registrable  Securities not later than the effective date
of the Registration Statement;

                  (i)  Cooperate   with  the  Investors  who  hold   Registrable
Securities  being offered to facilitate the timely  preparation  and delivery of
certificates  for the  Registrable  Securities  to be  offered  pursuant  to the
Registration   Statement  and  enable  such  certificates  for  the  Registrable
Securities  to be in such  denominations  or  amounts as the case may be, as the
Investors may reasonably  request,  and,  within three (3) business days after a
Registration   Statement  which  includes  Registrable   Securities  is  ordered
effective by the SEC, the Company shall  deliver,  and shall cause legal counsel
selected by the Company to deliver,  to the transfer  agent for the  Registrable
Securities  (with  copies to the  Investors  whose  Registrable  Securities  are
included in such Registration  Statement) an appropriate instruction and opinion
of such counsel; and

                  (j) Take all other  reasonable  actions  necessary to expedite
and  facilitate  disposition  by  the  Investor  of the  Registrable  Securities
pursuant to the Registration Statement.

                  4.       OBLIGATIONS OF THE INVESTORS.  In connection with the
registration of the Registrable Securities, the Investors shall have the
following obligations:

                  (a) 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  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.  At
least  five  (5)  days  prior  to  the  first  anticipated  filing  date  of the
Registration   Statement,   the  Company  shall  notify  each  Investor  of  the
information  the  Company  requires  from each  such  Investor  (the  "Requested
Information") if such Investor elects to have any of such Investor's Registrable
Securities included in the Registration  Statement. If at least two (2) business
days  prior to the  filing  date the  Company  has not  received  the  Requested
Information from an Investor (a "Non-Responsive Investor"), then the Company may
file the Registration Statement without including Registrable Securities of such
Non-Responsive Investor;

                  (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 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; and

                  (c) 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(e)
or 3(f),  above,  such  Investor will  immediately  discontinue  disposition  of
Registrable  Securities  pursuant to the  Registration  Statement  covering such
Registrable  Securities  until  such  Investor's  receipt  of the  copies of the
supplemented or amended prospectus  contemplated by Section 3(e) or 3(f) and, if
so directed by the Company,  such Investor  shall deliver to the Company (at the
expense of the Company) or destroy (and deliver to the Company a certificate  of
destruction)  all  copies  in  such  Investor's  possession,  of the  prospectus
covering  such  Registrable  Securities  current  at the time of receipt of such
notice.

                  5. EXPENSES OF REGISTRATION.  All reasonable  expenses,  other
than  underwriting   discounts  and  commissions  incurred  in  connection  with
registrations,  filings or qualifications  pursuant to Section 3, but including,
without limitation, all registration, listing, and qualifications fees, printers
and  accounting  fees,  the fees and  disbursements  of counsel for the Company,
shall be borne by the Company.

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


                                       19
<PAGE>


                  (a) To the extent permitted by law, the Company will indemnify
and hold  harmless  each  Investor who holds such  Registrable  Securities,  the
directors,  if any, of such  Investor,  the officers,  if any, of such Investor,
each  person,  if any,  who  controls  any  Investor  within the  meaning of the
Securities  Act  or  the  Exchange  Act  (each,  an   "Indemnified   Person"  or
"Indemnified  Party"),  against  any losses,  claims,  damages,  liabilities  or
expenses (joint or several)  incurred  (collectively,  "Claims") to which any of
them may become subject under the Securities Act, the Exchange Act or otherwise,
insofar  as such  Claims  (or  actions  or  proceedings,  whether  commenced  or
threatened,  in  respect  thereof)  arise  out of or are  based  upon any of the
following statements,  omissions or violations in the Registration Statement, or
any post-effective  amendment thereof, or any prospectus  included therein:  (i)
any untrue statement or alleged untrue statement of a material fact contained in
the  Registration  Statement  or any  post-effective  amendment  thereof  or the
omission or alleged  omission to state  therein 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
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 Securities Act, the Exchange Act, any state securities law or any
rule or  regulation  under the  Securities  Act,  the  Exchange Act or any state
securities  law (the matters in the  foregoing  clauses (i) through (iii) being,
collectively,  "Violations").  Subject  to  clause  (b) of this  Section  6, the
Company shall  reimburse the  Investors,  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) shall not (I) 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 or on behalf of any
Indemnified  Person  expressly for use in connection with the preparation of the
Registration Statement or any such amendment thereof or supplement thereto, (II)
be  available  to the extent such Claim is based on a failure of the Investor to
deliver or cause to be delivered the  prospectus  made available by the Company;
or (III) 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.  Each Investor will indemnify the Company and its
officers, directors and agents against any claims 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 or on behalf of such Investor, expressly
for use in  connection  with  the  preparation  of the  Registration  Statement,
subject  to  such   limitations   and   conditions  as  are  applicable  to  the
Indemnification  provided by the Company to this Section 6. 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)  Promptly  after  receipt  by  an  Indemnified  Person  or
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action  (including  any  governmental   action),   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. In case any such action is brought against any  Indemnified  Person
or Indemnified Party, and it notifies the indemnifying party of the commencement
thereof,  the indemnifying party will be entitled to participate in, and, to the
extent that it may wish,  jointly with any other  indemnifying  party  similarly
notified,  assume the defense thereof,  subject to the provisions  herein stated
and after  notice  from the  indemnifying  party to such  Indemnified  Person or
Indemnified  Party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party will not be liable to such Indemnified Person or Indemnified
Party  under  this  Section  6 for any legal or other  reasonable  out-of-pocket
expenses  subsequently  incurred by such Indemnified Person or Indemnified Party
in  connection  with  the  defense  thereof  other  than  reasonable   costs  of
investigation,  unless the indemnifying party shall not pursue the action of its
final  conclusion.  The Indemnified  Person or Indemnified  Party shall have the
right to employ  separate  counsel in any such action and to  participate in the
defense  thereof,  but the fees and  reasonable  out-of-pocket  expenses of such
counsel  shall  not  be  at  the  expense  of  the  indemnifying  party  if  the
indemnifying party has assumed the defense of the action with counsel reasonably
satisfactory  to the  Indemnified  Person or Indemnified  Party.  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,

                                       20

<PAGE>


except to the extent that the indemnifying party is prejudiced in its ability to
defend such action. 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 such expense, loss, damage or liability is incurred
and is due and payable.

                  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  (a)  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; (b) no seller of  Registrable
Securities guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to  contribution  from any seller
of   Registrable   Securities   who  was   not   guilty   of   such   fraudulent
misrepresentation;  and (c) 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 EXCHANGE ACT. With a view to making available
to the Investors the benefits of Rule 144  promulgated  under the Securities Act

which is hereby  acknowledged by StarBase  Corporation,  a Delaware  corporation
(the "Company") _________________ or registered assigns (the "Holder") is hereby
granted the right to  purchase at any time until 5:00 P.M.,  New York City time,
on  September  5, 2000 (the  "Expiration  Date"),  (___________)  fully paid and
nonassessable  shares of the Company's  Common  Stock,  par value $.01 per share
(the  "Common  Stock")  at an  initial  exercise  price of $1.80 per share  (the
"Exercise  Price"),  subject  to  further  adjustment  as set forth in Section 6
hereof.

9. EXERCISE OF WARRANTS.  This Warrant is exercisable in whole or in part at the
Exercise Price per share of Common Stock payable  hereunder,  payable in cash or

entitled to receive a certificate or certificates for the shares of Common Stock
so purchased.



10.  RESERVATION  OF SHARES.  The Company hereby agrees that at all times during
the term of this Warrant  there shall be reserved for issuance  upon exercise of
this  Warrant such number of shares of its Common Stock as shall be required for
issuance upon exercise of this Warrant (the "Warrant Shares").


11.  MUTILATION  OR LOSS OF  WARRANT.  Upon  receipt by the  Company of evidence
satisfactory  to it of the  loss,  theft,  destruction  or  mutilation  of  this
Warrant,  and (in the case of loss, theft or destruction)  receipt of reasonably

cancellation of this Warrant, the Company will execute and deliver a new Warrant

                   13.  PROTECTION AGAINST DILUTION.

(1)  ADJUSTMENT  MECHANISM.  If an adjustment of the Exercise  Price is required
pursuant to this Section 6, the Holder shall be entitled to purchase such number
of  additional  shares of  Common  stock as will  cause (I) the total  number of
shares of Common Stock Holder is entitled to purchase  pursuant to this Warrant,

to purchase  before  adjustment  multiplied by the total  purchase  price before
adjustment.

stock dividend,  reclassification of the Common Stock, recapitalization,  merger
or consolidation,  or like capital adjustment  affecting the Common Stock of the
Company,  the  provisions  of this Section 6 shall be applied as if such capital
adjustment event had occurred  immediately prior to the date of this Warrant and
the original  purchase  price had been fairly  allocated to the stock  resulting
from such  capital  adjustment;  and in other  respects the  provisions  of this
Section  shall be applied in a fair,  equitable and  reasonable  manner so as to
give effect,  as nearly as may be, to the purposes  hereof. A rights offering to
stockholders  shall be deemed a stock  dividend  to the  extent  of the  bargain
purchase element of the rights.

         3. This Debenture has been issued subject to investment representations
of the original  purchaser  hereof and may be  transferred  or exchanged only in
compliance  with the Securities  Act of 1933, as amended (the "Act"),  and other
applicable  state and  foreign  securities  laws.  In the event of any  proposed
transfer of this Debenture,  the Company may require, prior to issuance of a new
Debenture in the name of such other person,  that it receive reasonable transfer
documentation  including  opinions  that the  issuance of the  Debenture in such
other name does not and will not cause a violation of the Act or any  applicable
state or foreign  securities laws. Prior to due presentment for transfer of this
Debenture,  the  Company  and any agent of the  Company  may treat the person in
whose name this Debenture is duly registered on the Company's Debenture Register
as the owner hereof for the purpose of receiving  payment as herein provided and

         4. A.  Subject to Sections 4B and 4C, the Holder of this  Debenture  is
entitled,  at its option,  to convert at any time  commencing the earlier of (a)
ninety (90) days after the Issuance  Date,  or (b) at the option of the Company,
at any  time  after  the  effective  date of the  Registration  Statement  filed
pursuant  to the  Registration  Rights  Agreement  between  the  Company and the
Holder,  or the Holder's  predecessor in interest,  the principal amount of this
Debenture,  provided that the principal  amount is at least US $5,000 (unless if
at the time of such  election to convert the aggregate  principal  amount of all
Debentures  registered  to the  Holder is less that Five  Thousand  Dollars  (US
$5,000),  then the whole  amount  thereof)  into  shares of Common  Stock of the
Company at a conversion price for each share of Common Stock equal to the lesser
of (a) 100% of the Market  Price on the  Issuance  Date,  and (b) (i) 84% of the
Market Price on the Conversion  Date if such date is between ninety (90) and one
hundred twenty (120) days from the date hereof;  (ii) 80% of the Market Price if
the date is between one  hundred  twenty-one  (121) and one hundred  fifty (150)

purposes of this  Section 4, the Market  Price shall be the average  closing bid
price of the Common Stock on the five (5) trading days immediately preceding the
Issuance  Date or  Conversion  Date,  as may be  applicable,  as reported by the
National  Association  of  Securities  Dealers,  or the closing bid price on the
over-the-counter market on such date or, in the event the Common Stock is listed
on a stock exchange, the Market Price shall be the closing price on the exchange
on such date,  as  reported  in the Wall  Street  Journal.  Conversion  shall be
effectuated by  surrendering  the Debentures to be converted to the Company with
the form of  conversion  notice  attached  hereto as Exhibit A,  executed by the
Holder of the  Debenture  evidencing  such  Holder's  intention  to convert this
Debenture or a specified portion (as above provided) hereof, and accompanied, if
required by the Company, by proper assignment hereof in blank.  Interest accrued
or accruing  from the date of issuance to the date of conversion  shall,  at the
option of the Company,  be paid in cash or Common Stock upon  conversion  at the
Conversion Rate. 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. The date on which notice of conversion is given (the
"Conversion  Date")  shall be  deemed  to be the date on which  the  Holder  has
delivered  this  Debenture,  with the conversion  notice duly  executed,  to the
Company  or,  the date set forth in such  facsimile  delivery  of the  notice of
conversion if the Debenture is received by the Company within three (3) business
days therefrom. Facsimile delivery of the conversion notice shall be accepted by

business days from the date the notice of conversion with the original Debenture
is delivered to the Company.

                  B. The  Company  shall have the right to  require,  by written
notice to the  Holder  of this  Debenture  at least  ten (10) days  prior to the
Maturity  Date,  that  the  Holder  of this  Debenture  exercise  its  right  of
conversion  with  respect  to all or that  portion of the  principal  amount and
interest outstanding on the Maturity Date.

                  C. In lieu of converting  into Common Stock,  the Company will
have the  option of  partially  or fully  paying  cash to the Holder so that the
Holder will  realize the full  economic  benefit  the Holder  would  derive from
converting  the Debentures and selling the Common Stock at the closing ask price
on the Conversion  Date with no  transaction  fees. The Company agrees to notify
the Holder, in writing,  at least ten trading days in advance of any time period
in which it intends to exercise this option.

outstanding  Debentures  upon ten (10) days  written or  telecopy  notice to the
Holder.

of the Company,  which is absolute and  unconditional,  to pay the principal of,
and interest on, this Debenture at the time, place, and rate, and in the coin or
currency,  herein  prescribed.  This  Debenture and all other  Debentures now or
hereafter issued of similar terms are direct obligations of the Company.

         7. No recourse shall be had for the payment of the principal of, or the
interest  on, this  Debenture,  or for any claim based  hereon,  or otherwise in
respect hereof, against any incorporator,  shareholder,  officer or director, as
such,  past,  present or future,  of the Company or any  successor  corporation,
whether  by  virtue  of any  constitution,  statute  or rule  of law,  or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance  hereof and as part of the consideration for the issue hereof,
expressly waived and released.

         8. If the Company merges or  consolidates  with another  corporation or
sells or transfers all or substantially  all of its assets to another person and
the holders of the Common Stock are  entitled to receive  stock,  securities  or
property in respect of or in exchange for Common  Stock,  then as a condition of
such  merger,  consolidation,  sale  or  transfer,  the  Company  and  any  such
successor,  purchaser or transferee  agree that the Debenture may  thereafter be
converted  on the terms and subject to the  conditions  set forth above into the
kind and amount of stock,  securities or property  receivable  upon such merger,
consolidation,  sale or  transfer  by a holder of the number of shares of Common
Stock into which this  Debenture  might have been converted  immediately  before
such merger, consolidation, sale or transfer, subject to adjustments which shall
be as nearly  equivalent  as may be  practicable.  In the event of any  proposed
merger,  consolidation  or sale or transfer of all or  substantially  all of the
assets of the  Company (a  "Sale"),  the Holder  hereof  shall have the right to
convert by delivering a Notice of Conversion to the Company  within fifteen (15)
days of receipt of notice of such Sale from the Company. In the event the Holder
hereof  shall  elect not to  convert,  the  Company  may prepay all  outstanding
principal and accrued  interest on this Debenture,  less all amounts required by
law to be deducted,  upon which  tender of payment  following  such notice,  the
right of conversion shall terminate.

         9. The Holder of the Debenture,  by acceptance hereof, agrees that this
Debenture is being  acquired for investment and that such Holder will not offer,
sell or  otherwise  dispose  of this  Debenture  or the  shares of Common  Stock
issuable  upon  conversion  thereof  except under  circumstances  which will not
result in a  violation  of the Act or any  applicable  state Blue Sky or foreign
laws or similar laws relating to the sale of securities.

         10. This  Debenture  shall be governed by and  construed in  accordance
with the laws of the  State of New York.  Each of the  parties  consents  to the
jurisdiction  of the federal  courts whose  districts  encompass any part of the
City of New York or the state  courts of the  State of New York  sitting  in the
City of New York in connection with any dispute arising under this Agreement and
hereby waives, to the maximum extent permitted by law, any objection,  including
any  objection  based  ON  FORUM  NON  COVENIENS,  to the  bringing  of any such
proceeding in such jurisdictions.

Initial  Investor and the Company (the  "Securities  Purchase  Agreement"),  the
Company  has  agreed to issue and sell to the  Initial  Investor  one or more 6%
Convertible  Debentures  of the Company,  in an aggregate  principal  amount not

                  WHEREAS, to induce the Initial Investor to execute and deliver
the Securities  Purchase  Agreement,  the Company has agreed to provide  certain

                  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
Initial Investor hereby agrees as follows:

                  1.  DEFINITIONS.

                  (b)  As used in this Agreement, the following terms shall have
the following meanings:
                  (j)  "Investor" means the Initial Investor and any permitted
transferee  or assignee  who agrees to become  bound by the  provisions  of this
Agreement in accordance with Section 9 hereof.
                  (ii) "Register," "Registered," and "Registration" refer to a
registration  effected  by  preparing  and filing a  Registration  Statement  or
Statements in compliance  with the Securities Act and pursuant to Rule 415 under
the Securities 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 by the United  States  Securities  and Exchange
Commission (the "SEC").

                  (iii) "Registrable Securities" means the Conversion Shares and
the Warrant Shares.

                  (iv)  "Registration Statement" means a registration statement
of the Company under the Securities Act.

                  (b)  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 file
with the SEC a Registration  Statement on Form S-3 registering for resale by the
Investor a sufficient number of shares of Common Stock for the Initial Investors
(or such lesser  number as may be required by the SEC, but in no event less than


                                       35
<PAGE>
                                       

the number of shares  into which the  Debentures  would be  convertible  and the
Warrants  exercisable  at the time of filing of the Form S-3, or an amendment to
any pending Company  Registration  Statement on Form S-3, and such  Registration
Statement or amended Registration Statement shall state that, in accordance with
Rule 416 and 457 under the  Securities  Act, it also  covers such  indeterminate
number  of  additional  shares  of  Common  Stock as may  become  issuable  upon
conversion of the  Debentures  and the exercise of the Warrants  resulting  from
adjustment in the Conversion Price, or to prevent dilution  resulting from stock
splits,  or stock  dividends),  which  Registration  Statement shall be declared
effective  no later  than 90 days  after the  Closing  Date.  If at any time the
number of shares of Common  Stock into  which the  Debentures  may be  converted
exceeds the  aggregate  number of shares of Common  Stock then  registered,  the
Company  shall,  within ten (10) business days after receipt of a written notice
from any  Investor,  either (i) amend the  Registration  Statement  filed by the
Company pursuant to the preceding sentence,  if such Registration  Statement has
not been  declared  effective by the SEC at that time, to register all shares of
Common  Stock  into  which  the  Debentures  may be  converted,  or (ii) if such
Registration Statement has been declared effective by the SEC at that time, file
with the SEC an  additional  Registration  Statement on Form S-3 to register the
shares of Common Stock into which the  Debentures  may be converted  that exceed
the aggregate number of shares of Common Stock already registered.

                  (B)   PAYMENTS BY THE COMPANY.

                          If the Registration Statement covering the Registrable
Securities  required to be filed by the Company  pursuant to Section 2(a) hereof
is not  effective by ninety (90) days  following  the initial  Closing Date (the
"Required  Effective  Date") (except as provided by the last sentence of section
2a), then the Company will make payments to the Initial Investor in such amounts
and at such times as shall be  determined  pursuant to this  Section  2(b).  The
amount to be paid by the Company to the Initial  Investor shall be determined as
of each Computation  Date, and such amount shall be equal to one (1%) percent of
the  purchase  price  paid  by the  Initial  Investor  for all  Debentures  then
purchased and outstanding  pursuant to the Securities Purchase Agreement for any
period from the Required  Effective Date to the first Computation Date, two (2%)
percent to the next  Computation Date and three (3%) percent to each Computation
Date thereafter,  until the Registration  Statement is declared effective by the
SEC (the  "Periodic  Amount").  The full  Periodic  Amount  shall be paid by the
Company in  immediately  available  funds within three  business days after each
Computation  Date.  Notwithstanding  the foregoing,  the amounts  payable by the
Company  pursuant to this provision shall not be payable to the extent any delay
in the effectiveness of the Registration  Statement occurs because of an act of,
or a failure to act or to act timely by the  Initial  Investor or its counsel or
the SEC, or in the event all of the Registrable  Securities may be sold pursuant
to Rule 144 or another available exemption under the Act.

                  As used in this Section 2(b),  the following  terms shall have
the following meanings:

                  "Computation  Date"  means the date which is thirty  (30) days
after the Required  Effective  Date (except as provided by the last  sentence of
section 2(a)),  and, if the Registration  Statement  required to be filed by the
Company pursuant to Section 2(a) has not theretofore been declared  effective by
the SEC, each date which is thirty (30) days after the previous Computation Date
(pro rated for partial periods) until such Registration Statement is so declared
effective.

                  3.       OBLIGATIONS OF THE COMPANY.  In connection with the
registration  of the  Registrable  Securities,  the Company shall do each of the
following.

                  (a)  Prepare promptly and file with the SEC, a Registration
Statement  with  respect to not less than the number of  Registrable  Securities
provided in Section 2(a),  above, and thereafter use its reasonable best efforts
to cause each  Registration  Statement  relating to  Registrable  Securities  to
become  effective  ninety  (90)  days  after  the  Closing  Date,  and  keep the
Registration   Statement   effective  at  all  times  until  the  earliest  (the
"Registration  Period") of (i) the date that is two years after the Closing Date
(ii) the date when the Investors may sell all Registrable  Securities under Rule
144 or  (iii)  the date  the  Investors  no  longer  own any of the  Registrable
Securities,   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;


                                      36
<PAGE>


                  (b) Prepare and file with the SEC such  amendments  (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus  used  in  connection  with  the  Registration  Statement  as  may be
necessary  to  keep  the   Registration   effective  at  all  times  during  the
Registration  Period,  and,  during the  Registration  Period,  comply  with the
provisions  of  the  Securities  Act  with  respect  to the  disposition  of all
Registrable  Securities  of the Company  covered by the  Registration  Statement
until such time as all of such  Registrable  Securities 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;

                  (c)  The  Company  shall  permit  a  single  firm  of  counsel
designated by the Initial Investors to review the Registration Statement and all
amendments and  supplements  thereto a reasonable  period of time prior to their
filing with the SEC.

                  (d) Furnish to each Investor whose Registrable  Securities are
included in the Registration  Statement and its legal counsel  identified to the
Company, (i) promptly after the same is prepared and publicly distributed, filed
with the SEC,  or  received  by the  Company,  one (1) copy of the  Registration
Statement,  each  preliminary  prospectus and prospectus,  and each amendment or
supplement  thereto,  and (ii) such  number of copies of a  prospectus,  and all
amendments and supplements  thereto and such other  documents,  as such Investor
may reasonably request in order to facilitate the disposition of the Registrable
Securities owned by such Investor;

                  (e) As promptly as  practicable  after  becoming aware of such
event,  notify each  Investor of the happening of any event of which the Company
has knowledge,  as a result of which the prospectus included in the Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits 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 use its best efforts promptly to prepare a supplement
or amendment to the Registration  Statement or other appropriate filing with the
SEC to correct such untrue statement or omission, and deliver a number of copies
of such supplement or amendment to each Investor as such Investor may reasonably
request;

                  (f) As promptly as  practicable  after  becoming aware of such
event, notify each Investor who holds Registrable  Securities being sold (or, in
the  event  of an  underwritten  offering,  the  managing  underwriters)  of the
issuance by the SEC of a Notice of  Effectiveness or any notice of effectiveness
or any stop order or other  suspension of the  effectiveness of the Registration
Statement at the earliest possible time;

                  (g)  Use its  reasonable efforts to secure designation of all
the Registrable  Securities covered by the Registration  Statement as a National
Association of Securities Dealers Automated  Quotations System ("NASDAQ") "Small
Capitalization"  within  the  meaning  of  Rule  11Aa2-1  of the SEC  under  the
Securities  Exchange  Act of 1934,  as amended  (the  "Exchange  Act"),  and the
quotation of the Registrable  Securities on the NASDAQ SmallCap  Market;  or if,
despite the Company's  reasonable  efforts to satisfy the preceding clause,  the
Company  is  unsuccessful  in doing  so,  to secure  NASDAQ/OTC  Bulletin  Board
authorization  and  quotation  for  such  Registrable  Securities  and,  without
limiting the  generality  of the  foregoing,  to arrange for at least two market
makers to register with the National  Association  of Securities  Dealers,  Inc.
("NASD") as such with respect to such Registrable Securities;

                  (h)  Provide a transfer  agent and  registrar,  which may be a
single entity, for the Registrable  Securities not later than the effective date
of the Registration Statement;

                  (i)  Cooperate   with  the  Investors  who  hold   Registrable
Securities  being offered to facilitate the timely  preparation  and delivery of
certificates  for the  Registrable  Securities  to be  offered  pursuant  to the
Registration   Statement  and  enable  such  certificates  for  the  Registrable
Securities  to be in such  denominations  or  amounts as the case may be, as the
Investors may reasonably  request,  and,  within three (3) business days after a
Registration   Statement  which  includes  Registrable   Securities  is  ordered
effective by the SEC, the Company shall  deliver,  and shall cause legal counsel
selected by the Company to deliver,  to the transfer  agent for the  Registrable
Securities  (with  copies to the  Investors  whose  Registrable  Securities  are
included in such Registration  Statement) an appropriate instruction and opinion
of such counsel; and


                                       37
<PAGE>


                  (j) Take all other  reasonable  actions  necessary to expedite
and  facilitate  disposition  by  the  Investor  of the  Registrable  Securities
pursuant to the Registration Statement.

                  4.       OBLIGATIONS OF THE INVESTORS.  In connection with the
registration  of the  Registrable  Securities,  the  Investors  shall  have  the
following obligations:

                  (a) 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  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.  At
least  five  (5)  days  prior  to  the  first  anticipated  filing  date  of the
Registration   Statement,   the  Company  shall  notify  each  Investor  of  the
information  the  Company  requires  from each  such  Investor  (the  "Requested
Information") if such Investor elects to have any of such Investor's Registrable
Securities included in the Registration  Statement. If at least two (2) business
days  prior to the  filing  date the  Company  has not  received  the  Requested
Information from an Investor (a "Non-Responsive Investor"), then the Company may
file the Registration Statement without including Registrable Securities of such
Non-Responsive Investor;

                  (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 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; and

                  (c) 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(e)
or 3(f),  above,  such  Investor will  immediately  discontinue  disposition  of
Registrable  Securities  pursuant to the  Registration  Statement  covering such
Registrable  Securities  until  such  Investor's  receipt  of the  copies of the
supplemented or amended prospectus  contemplated by Section 3(e) or 3(f) and, if
so directed by the Company,  such Investor  shall deliver to the Company (at the
expense of the Company) or destroy (and deliver to the Company a certificate  of
destruction)  all  copies  in  such  Investor's  possession,  of the  prospectus
covering  such  Registrable  Securities  current  at the time of receipt of such
notice.

                  5. EXPENSES OF REGISTRATION.  All reasonable  expenses,  other
than  underwriting   discounts  and  commissions  incurred  in  connection  with
registrations,  filings or qualifications  pursuant to Section 3, but including,
without limitation, all registration, listing, and qualifications fees, printers
and  accounting  fees,  the fees and  disbursements  of counsel for the Company,
shall be borne by the Company.

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

                  (a)      To the extent permitted by law, the Company will
indemnify and hold harmless each Investor who holds such Registrable Securities,
the directors, if any, of such Investor, the officers, if any, of such Investor,
each  person,  if any,  who  controls  any  Investor  within the  meaning of the
Securities  Act  or  the  Exchange  Act  (each,  an   "Indemnified   Person"  or
"Indemnified  Party"),  against  any losses,  claims,  damages,  liabilities  or
expenses (joint or several)  incurred  (collectively,  "Claims") to which any of
them may become subject under the Securities Act, the Exchange Act or otherwise,
insofar  as such  Claims  (or  actions  or  proceedings,  whether  commenced  or
threatened,  in  respect  thereof)  arise  out of or are  based  upon any of the
following statements,  omissions or violations in the Registration Statement, or
any post-effective  amendment thereof, or any prospectus  included therein:  (i)
any untrue statement or alleged untrue statement of a material fact contained in
the  Registration  Statement  or any  post-effective  amendment  thereof  or the
omission or alleged  omission to state  therein 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


                                       38
<PAGE>


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 Securities Act, the Exchange Act, any state securities law or any
rule or  regulation  under the  Securities  Act,  the  Exchange Act or any state
securities  law (the matters in the  foregoing  clauses (i) through (iii) being,
collectively,  "Violations").  Subject  to  clause  (b) of this  Section  6, the
Company shall  reimburse the  Investors,  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) shall not (I) 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 or on behalf of any
Indemnified  Person  expressly for use in connection with the preparation of the
Registration Statement or any such amendment thereof or supplement thereto, (II)
be  available  to the extent such Claim is based on a failure of the Investor to
deliver or cause to be delivered the  prospectus  made available by the Company;
or (III) 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.  Each Investor will indemnify the Company and its
officers, directors and agents against any claims 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 or on behalf of such Investor, expressly
for use in  connection  with  the  preparation  of the  Registration  Statement,
subject  to  such   limitations   and   conditions  as  are  applicable  to  the
Indemnification  provided by the Company to this Section 6. 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)      Promptly after receipt by an Indemnified Person or 
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action  (including  any  governmental   action),   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. In case any such action is brought against any  Indemnified  Person
or Indemnified Party, and it notifies the indemnifying party of the commencement
thereof,  the indemnifying party will be entitled to participate in, and, to the
extent that it may wish,  jointly with any other  indemnifying  party  similarly
notified,  assume the defense thereof,  subject to the provisions  herein stated
and after  notice  from the  indemnifying  party to such  Indemnified  Person or
Indemnified  Party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party will not be liable to such Indemnified Person or Indemnified
Party  under  this  Section  6 for any legal or other  reasonable  out-of-pocket
expenses  subsequently  incurred by such Indemnified Person or Indemnified Party
in  connection  with  the  defense  thereof  other  than  reasonable   costs  of
investigation,  unless the indemnifying party shall not pursue the action of its
final  conclusion.  The Indemnified  Person or Indemnified  Party shall have the
right to employ  separate  counsel in any such action and to  participate in the
defense  thereof,  but the fees and  reasonable  out-of-pocket  expenses of such
counsel  shall  not  be  at  the  expense  of  the  indemnifying  party  if  the
indemnifying party has assumed the defense of the action with counsel reasonably
satisfactory  to the  Indemnified  Person or Indemnified  Party.  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. 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 such expense, loss, damage or liability is incurred
and is due and payable.

                  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  (a)  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; (b) no seller of  Registrable


                                       39
<PAGE>


Securities guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to  contribution  from any seller
of   Registrable   Securities   who  was   not   guilty   of   such   fraudulent
misrepresentation;  and (c) 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 EXCHANGE ACT. With a view to making available
to the Investors the benefits of Rule 144  promulgated  under the Securities 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 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
otherdocuments  required of the Company  under the  Securities  Act and the
Exchange Act; and

                  (c)  furnish to each  Investor so long as such  Investor  owns

Company that it has complied  with the reporting  requirements  of Rule 144, the
Securities  Act and the Exchange  Act,  (ii) a copy of the most recent annual or

automatically  assigned by the Investors to any  transferee  of the  Registrable
Securities  (or all or any  portion of any  Debenture  of the  Company  which is
convertible  into such  securities)  only if: (a) the Investor agrees in writing
with the  transferee  or  assignee  to assign  such  rights,  and a copy of such
agreement  is  furnished  to the  Company  within a  reasonable  time after such
assignment,  (b) the Company is, within a reasonable time after such transfer or
assignment,  furnished  with written  notice of (i) the name and address of such

such transfer or assignment the further  disposition  of such  securities by the
transferee or assignee is restricted  under the  Securities  Act and  applicable
state  securities  laws, and (d) at or before the time the Company  received the
written  notice  contemplated  by clause (b) of this sentence the  transferee or
assignee agrees in writing with the Company to be bound by all of the provisions
contained  herein.  In the event of any delay in filing or  effectiveness of the
Registration Statement as a result of such assignment,  the Company shall not be
liable for any damages  arising  from such delay,  or the  payments set forth in
Section 2(c) hereof.

                  10.  AMENDMENT OF REGISTRATION  RIGHTS.  Any provision 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
hold an  eighty  (80%)  percent  interest  of the  Registrable  Securities.  Any
amendment or waiver effected in accordance with this Section 10 shall be binding
upon each Investor and the Company.

                  (a) A person or entity is deemed to be a holder of Registrable

Securities.
