delivered to or upon the written order of the registered holder(s) of such 
Warrants and in such name or names as such registered holder(s) may designate, a
certificate for the Warrant Share or Warrant Shares issued upon such exercise of
such Warrants. Any Person(s) so designated to be named therein shall be deemed 
to have become holder(s) of record of such Warrant Share or Warrant Shares as of
the date of exercise of such Warrants.

are exercised at any time, a new Warrant Certificate or Certificates shall be 
issued for the remaining number of Warrants evidenced by such Warrant 
Certificate. Each new Warrant Certificate so issued shall bear the legend set 
forth in Section 14(b) if the Warrant Certificate presented in connection with 
partial exercise thereof bore such legend. All Warrant Certificates surrendered

provided that Issuer shall not be required to pay any tax which may be payable 
in respect of any transfer involved in the issue of any Warrant Certificate or 
any Certificate for Warrant Shares in a name other than that of the registered 
holder of a Warrant Certificate surrendered upon the exercise of a Warrant, and 
Issuer shall not be required to issue or deliver such certificates unless or 
until the person or persons requesting the issuance thereof shall have paid to 
Issuer the amount of such tax or shall have established to the satisfaction of 
Issuer that such tax has been paid.

                                  SECTION 9.
              WARRANT HOLDER RIGHTS: DIVIDENDS AND DISTRIBUTIONS
              --------------------------------------------------

     The Warrants shall not (prior to exercise hereof) confer upon the holders 
thereof the right to vote as shareholders of Issuer, the right to receive 
dividends or distributions of Issuer if declared and paid or any other right as 
shareholders of Issuer.

                                      -7-

 
                                  SECTION 10.
                  RESERVATION AND ISSUANCE OF WARRANT SHARES
                  ------------------------------------------

     (a)   Issuer will at all times have authorized, and reserve and keep 
available, free from preemptive rights, for the purpose of enabling it to 
satisfy any obligation to issue Warrant shares upon the exercise of the 
Warrants, the number of shares of Common Stock deliverable upon exercise of all 
outstanding Warrants.

     (b)   Before taking any action which would cause an adjustment pursuant to 
Section 12 hereof reducing the Exercise Price below the then par value (if any) 
of the Warrant Shares issuable upon exercise of the Warrants, Issuer will take 
any corporate action which may be necessary in order that Issuer may validly and
legally issue fully paid and nonassessable Warrant Shares at the Exercise Price
as so adjusted.

     (c)   Issuer covenants that all Warrant Shares will, upon issuance in 
accordance with the terms of this Warrant Agreement, be fully paid and 
nonassessable and free from all taxes with respect to the issuance thereof and 
from all liens, charges and security interests created (whether by affirmative 
action or inaction) by Issuer.

                                  SECTION 11.
                      OBTAINING OF GOVERNMENTAL APPROVALS
                      -----------------------------------
                          AND STOCK EXCHANGE LISTINGS
                          ---------------------------

     Issuer will, at its own expense, (a) obtain and keep effective any and all 
permits, consents and approvals of Governmental Authorities which may from time 
to time be required of Issuer in order to satisfy its obligations hereunder, and
(b) take all action which may be necessary so that the Warrant Shares, 
immediately upon their issuance upon the exercise of Warrants, will be listed on
each securities exchange, if any, on which the Common Stock is then listed.

                                  SECTION 12.
                       ADJUSTMENT OF EXERCISE PRICE AND
                       --------------------------------
                     NUMBER OF WARRANT SHARES PURCHASABLE
                     ------------------------------------

     Prior to the Expiration Date, the Exercise Price and the number of Warrant 
Shares purchasable upon the exercise of each Warrant are subject to adjustment 
from time to time upon the occurrence of any of the events enumerated in this 
Section 12.

     (a)   In the event that Issuer shall at any time after the date of this 
Agreement (i) declare a dividend on Common Stock in shares of Common Stock or 
other securities of Issuer, (ii) split or subdivide the outstanding Common 
Stock, (iii) combine the outstanding Common Stock into a smaller number of 
shares, or (iv) issue by reclassification of its Common Stock any shares or 
other securities of Issuer, then, in each such event, the number of Warrant 
Shares purchasable upon exercise of each Warrant immediately prior thereto shall
be adjusted so that the holder shall be entitled to receive the kind and number 
of such shares or other securities of Issuer which the holder

                                      -8-

 
would have owned or have been entitled to receive after the happening of any of 
the events described above had such Warrant been exercised immediately prior to 
the happening of such event (or any record date with respect thereto). Such 
adjustment shall be made whenever any of the events listed above shall occur. An
adjustment made pursuant to this paragraph (a) shall become effective 
immediately after the effective date of the event retroactive to the record 
date, if any, for the event.

     (b)   (i)   In the event that Issuer shall at any time after the date of 
this Agreement issue any shares of Common Stock or other securities convertible 
into shares of Common Stock (excluding shares of Common Stock issued upon 
exercise of the Warrants) at a price below the then applicable Exercise Price of
the Warrants or Fair Market Price Per Share, then in each such event (an 
"Adjustment Event"), the number of Warrant Shares purchasable upon exercise of 
 ----------------
each Warrant immediately prior thereto shall be adjusted so that the holder of 
any Series A Warrant, Series B Warrant or Series C Warrant, as the case may be, 
exercised shall be entitled to receive the number of Warrant Shares (the 
"Adjusted Number") determined by multiplying the number of Warrant Shares 
 ---------------
purchasable upon exercise of such Warrants immediately prior thereto by a 
fraction determined by multiplying the number of Warrant Shares of such series 
purchasable upon exercise of such Warrants immediately prior thereto by a 
fraction determined by dividing (x) a number (the "Aggregate Adjusted Number") 
                                                   -------------------------
equal to the Warrant Percentage of the sum of (A) the number of shares of Common
Stock outstanding immediately following such Adjustment Event (assuming the 
exercise of all outstanding Warrants), plus (B) the Aggregate Adjusted Number of
                                       ----
Warrant Shares by (y) the number of unexercised Warrants of such series 
               --
outstanding at the time such calculation is made; provided, however, that no 
                                                  --------  -------
such adjustment shall be made for the issuance of shares of Common Stock under 
the circumstances contemplated in Section 12(f) hereof. Notwithstanding the 
foregoing, the issue of Common Stock pursuant to exercise of options granted 
under the Company's stock option plans or pursuant to exercise of warrants 
existing on the date hereof shall not be an Adjustment Event.

           (ii)  In the event that at any time after the date of this Agreement,
Issuer shall in any manner grant any Rights or issue or sell any Convertible 
Securities, then the total maximum number of shares of Common Stock issuable 
pursuant to such Rights or upon conversion or exchange of the total maximum 
amount of such Convertible Securities shall (as of the later to occur of (x) the
date of the granting of such Rights or issuance or sale of such Convertible 
Securities or (y) the date such rights become exercisable or such Convertible 
Securities become convertible) be deemed to be outstanding and to have been 
issued or sold for purposes of paragraph (b) (i) hereof; provided, that, except 
                                                         --------
as provided in the following proviso, no further adjustment of the number of 
Warrant Shares issuable upon exercise of the Warrants shall be made upon the 
actual issue of shares of Common Stock so deemed to have been issued, and 
further provided, that, upon the expiration or termination of any unexercised 
- ----------------
Rights or conversion or exchange privileges for which any adjustment was made 
pursuant to paragraph (b) (i) and this paragraph (b) (ii), then the number of 
Warrant Shares issuable upon exercise of the Warrants shall be readjusted, and 
shall thereafter be such number as would have prevailed had the number of shares
of Common Stock issuable upon exercise of the Warrants been originally adjusted 
(or had the original adjustment not been required, as the case may be) on the 
basis of the shares of Common Stock, if any, actually issued or sold upon the 
exercise of such Rights or conversion or exchange privileges; provided, however,
                                                              --------  -------
that no such readjustment shall have the effect of decreasing the number of 
Warrant Shares issuable upon exercise of the Warrants by an amount in

                                      -9-

 
excess of the amount of the adjustment initially made for the issuance, sale or 
grant of such Rights or Convertible Securities.

     (c)   No adjustment in the number of Warrant Shares shall be required 
unless such adjustment would require an increase or decrease of at least 1% in 
the aggregate number of Warrant Shares purchasable upon exercise of all 
Warrants; provided that any adjustments which by reason of this Section 12(c) 
          --------
are not required to be made shall be carried forward and taken into account in 
any subsequent adjustment; provided, however, that notwithstanding the 
                           --------
foregoing, all such adjustments shall be made no later than three years from the
date of the first event that would have required an adjustment but for this
paragraph. All calculations under this Section 12 shall be made to the nearest
cent or to the nearest hundredth of a share, as the case may be.

     (d)   If at any time, as a result of an adjustment made pursuant to this 
Section 12, the holder of any Warrant thereafter exercised shall become entitled
to receive any shares of Issuer other than shares of Common Stock, thereafter 
the number of such other shares so receivable upon exercise of any Warrant shall
be subject to adjustment from time to time in a manner and on terms as nearly 
equivalent as practicable to the provisions with respect to the Warrant Shares 
contained in this Section 12, and the provisions of this Agreement with respect 
to the Warrant Shares shall apply on like terms to such other shares.

     (e)   Whenever the number of Warrant Shares purchasable upon the exercise 
of a Warrant is adjusted, the Exercise Price per Warrant Share payable upon 
exercise of such Warrant shall be adjusted by multiplying such Exercise Price 
immediately prior to such adjustment by a fraction, the numerator of which shall
be the number of Warrant Shares purchasable upon the exercise of such Warrant 
immediately prior to such adjustment, and the denominator of which shall be the 
number of Warrant Shares purchasable immediately after such adjustment.

     (f)   In the event of any capital reorganization of Issuer, or of any 
reclassification of the Common Stock (other than a reclassification referred to 
in paragraph (a) (iv) above), or in case of the consolidation of Issuer with or 
the merger of Issuer with or into any other corporation (other than a 
consolidation or merger in which the Company is the surviving corporation) or of
the sale the properties and assets of Issuer as, or substantially as, an 
entirety to any other corporation, each Warrant shall, after such capital 
reorganization, reclassification of Common Stock, consolidation, merger or sale,
and in lieu of being exercisable for Warrant Shares, be exercisable, upon the 
terms and conditions specified in this Warrant Agreement, for the number of 
shares of stock or other securities or assets to which holder of the number of 
Warrant Shares purchasable upon exercisable of such Warrant immediately prior to
such capital organization, reclassification of Common Stock, consolidation, 
merger or sale would have been entitled upon such capital organization, 
reclassification of Common Stock, consolidation, merger or sale; and in any such
case, if necessary, the provisions set forth in this Section 12 with respect to 
the rights thereafter of the holders of the Warrants shall be appropriately 
adjusted so as to be applicable, as nearly as they may reasonably be, to any 
shares of stock or other securities or assets thereafter deliverable on the 
exercise of the Warrants. Issuer shall not effect any such consolidation, merger
or sale, unless prior to or simultaneously with the

                                     -10-

 
consummation thereof, the successor corporation (if other than Issuer) resulting
from such consolidation or merger or the corporation purchasing such assets or
the appropriate corporation or entity shall assume, by written instrument, the
obligation to deliver to holder of each Warrant the shares of stock, securities
or assets to which, in accordance with the foregoing provisions, such holder may
be entitled and all other obligations of Issuer under this Warrant Agreement.
The provisions of this paragraph (f) shall apply to successive reorganizations,
reclassification, consolidations, mergers and sales.

     (g)  Irrespective of any adjustments in the Exercise Price or the number or
kind of shares purchasable upon exercise of the Warrants, Warrant Certificates 
theretofore or thereafter issued may continue to express the same Exercise Price
per share and number and kind of shares as are stated on the Warrant 
Certificates initially issuable pursuant to this Agreement.

     (h)  If any question shall at any time arise with respect to the adjusted 
Exercise Price or Warrant Shares issuable upon exercise, such question shall be 
determined by the independent auditors of Issuer and such determination shall be
binding upon Issuer and the holders of the Warrants and Warrant Shares.

     (i)  In case any event shall occur as to which the other provisions of this
Section 12 are not strictly applicable the failure to make any adjustment would 
result in an unfair enlargement or dilution of the purchase rights represented 
by the Warrants in accordance with the essential intent and principles hereof, 
then, in each such case, the independent auditors of Issuer shall give its 
opinion as to the adjustment, if any, on a basis consistent with the essential 
intent and principles established in this Section 12, necessary to preserve, 
without enlargement or dilution, the purchase rights presented by the Warrants. 
Upon receipt of such opinion, Issuer shall promptly mail a copy thereof to the 
registered holders of the Warrants and shall make the adjustment described 
therein.

                                  SECTION 13.
                          NOTICES TO WARRANT HOLDERS
                          --------------------------

     Upon any adjustment of the Exercise Price or number of Warrant Shares 
issuable upon exercise pursuant to Section 12, Issuer shall promptly, but in any
event within 10 days thereafter, cause to be given to each of the registered 
holders of the Warrants, at its address appearing on the Warrant Register by 
first-class mail, postage prepaid, a certificate signed by its chief financial 
officer setting forth the Exercise Price as so adjusted and/or number of Warrant
Shares issuable upon the exercise of each Warrant as so adjusted and describing 
in reasonable detail the facts accounting for such adjustment and the method of 
calculation used. Where appropriate, such certificate may be given in advance 
and included as a part of the notice required to be mailed under the other 
provisions of this Section 13.

     In the event:

                                     -11-

 
     (a)  Issuer shall authorize the grant of Rights or the offer or issuance of
Common Stock or Convertible Securities to holders of Common Stock; or

     (b)  Issuer shall declare a dividend or other distribution to all holders 
of Common Stock payable in evidences of its indebtedness, securities, cash or 
assets; or

     (c) of any consolidation or merger to which Issuer is a party and for which
approval of any shareholders of Issuer is required, or of the conveyance or
transfer of the properties and assets of Issuer substantially as an entirety, or
of any capital reorganization or reclassification or change of the Common Stock
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination); or

     (d)  of the voluntary or involuntary dissolution, liquidation or winding up
of Issuer; or

     (e)  Issuer shall authorize any other action which would require an 
adjustment of the Exercise Price or number of Warrant Shares issuable upon 
exercise pursuant to Section 12;

then Issuer shall cause to be given to each of the registered holders of the 
Warrants at its address appearing on the Warrant Register, at least 12 business 
days prior to the applicable record date hereinafter specified (or as 
expeditiously as possible after the occurrence of any involuntary dissolution, 
liquidation or winding up referred to in clause (d) above), by first-class mail,
postage prepaid, a written notice stating (i) the date as of which the holders 
of record of Common Stock to be entitled to receive any such rights, warrants or
distribution are to be determined, or (ii) the date on which any such 
consolidation, merger, conveyance, transfer, dissolution, liquidation or winding
up is expected to become effective (or has become effective, in the case of any 
involuntary dissolution, liquidation or winding up), and the date as of which it
is expected that holders of record of Common Stock shall be entitled to exchange
their shares for securities or other property, if any, deliverable upon such 
reclassification, consolidation, merger, conveyance, transfer, dissolution,
liquidation or winding up. The failure to give the notice required by this
Section 13 or any defect therein shall not affect the legality or validity any
distribution, right, warrant, consolidation, merger, conveyance, transfer,
dissolution, liquidation or winding up, or vote upon any action.

                                  SECTION 14.
                           RESTRICTIONS ON TRANSFER
                           ------------------------

     (a)  Each Holder and JBO represents (and upon any exercise of the Warrants 
represents) that:

               (i)  it is an accredited investor as that term is defined in the 
Securities Act if such investor is a domiciliary or citizen of the United 
States, or

                                     -12-

 
          (ii) if the investor is not a domiciliary or citizen of the United
states, that the Offer or sale of the Units and the Common Stock issuable upon
exercise of the Warrants will only be made (i) pursuant to an exemption from the
registration requirements of the Securities Act, or (ii) if the offer is not
made to a person in the United States, and either (A) at time the buy order is
originated, the buyer is outside the United States, or the seller and any person
acting on its behalf reasonably believe that the buyer is outside the United
States, or (B) the transaction is executed in, on or through the facilities of a
designated offshore securities market outside the United States, as specified in
Rule 902(a) of Regulation S, and neither the seller nor any person acting on its
behalf knows that the transaction has been pre-arranged with a buyer in the
United States. In addition, such sellers will not (and no one acting on their
behalf will) solicit purchasers in the United States or otherwise engage in
selling efforts in the United States.

     Such purchasers of the Units will resell the securities comprising the 
Units only (i) in accordance with Rule 904 of Regulation S under the Securities 
Act, (ii) pursuant to an exemption from registration under the Securities Act, 
or (iii) in a transaction registered under the Securities Act. Additionally, 
prior to forty days after the closing of the offering (the "Restricted Period"),
the securities will not be offered or sold in the United States or to U.S. 
persons as defined by Rule 902(o) of the Regulation S, other than to 
distributors, unless the securities are registered under the Securities Act, or 
an exemption from the registration requirements of the Securities Act is 
available. In addition, a holder of the securities who is a distributor, dealer,
subunderwriter or other securities professional, will not prior to the 
expiration of the restricted period resell the securities to a U.S. person as 
defined by Rule 902(o) of Regulation S unless the securities are registered 
under the Securities Act, or an exemption from registration under the Act is 
available.

          (iii) it will be acquiring the Warrant Shares for its own account, for
investment and not with a view to any distribution public offering within the 
meaning of the Securities Act but subject to any requirement of law that the 
disposition of its property shall at all times be within its control.

     (b)  Each Holder and JBO acknowledges that the Warrants and the Non Public 
Warrant Shares issuable upon exercise thereof have not been registered and will 
not be registered except as otherwise provided herein under the Securities Act 
and agrees that it will not sell or otherwise transfer any of its Warrants or 
Non Public Warrant Shares except upon the terms and conditions specified herein.

     (c)  (i)  Each Holder and JBO agrees, and each subsequent transferee 
described in paragraph (ii) below shall agree, that it will not transfer any 
Warrants or Non Public Warrant Shares except:

               (A)  pursuant to Rule 144 under the Securities Act;

               (B)  pursuant to Rule 144A under the Securities Act;

               (C)  pursuant to Regulation S under the Securities Act;

                                     -13-

 
                 (D)  pursuant to any other exemption from, or otherwise in a
                      transaction not subject to, the registration requirements
                      of the Securities Act (as confirmed in an opinion of
                      counsel to the transferor to the effect that the proposed
                      transfer may be effected without registration under the
                      Securities Act);
                 (E)  outside the United States in compliance with Rule 904 
                      under the Securities Act;
                 (F)  a transfer by such Holder or JBO, as the case may be, to
                      any Affiliate or wholly owned Subsidiary of such Holder or
                      JBO, as the case may be, (including any partnership or
                      limited partnership of which such Holder or JBO, as the
                      case may be, or any Affiliate thereof is a general
                      partner); or
                 (G)  pursuant to an effective registration statement under the 
                      Securities Act.

          (ii)   Each Warrant Certificate and each certificate for the Warrant 
Shares issued to a Holder or JBO or to a subsequent transferee pursuant to 
Section 14(c) (i) (B), (D) (unless the legal opinion delivered in connection
therewith is to the effect that the first paragraph of such legend is not 
required in order to ensure compliance with the Securities Act) or (E) shall 
include a legend in substantially the following form:

              THE [WARRANTS AND UNDERLYING SHARES] [SHARES] REPRESENTED BY THIS
              CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
              1933, AS AMENDED, (THE "ACT") AND MAY NOT BE SOLD OR TRANSFERRED
              EXCEPT PURSUANT TO AN EXEMPTION FROM, OR OTHERWISE IN A
              TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF SUCH
              ACT. IN ADDITION, THE [WARRANTS AND UNDERLYING SHARES] [SHARES]
              MAY BE TRANSFERRED ONLY IN COMPLIANCE WITH THE CONDITIONS
              SPECIFIED IN THE WARRANT AGREEMENT, DATED NOVEMBER 21, 1995,
              BETWEEN ISSUER AND THE INITIAL HOLDER OF THE WARRANTS NAMED
              THEREIN, A COMPLETE AND CORRECT COPY OF WHICH IS AVAILABLE FOR
              INSPECTION AT THE PRINCIPAL OFFICE OF ISSUER AND WILL BE FURNISHED
              TO THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT CHARGE. THIS
              WARRANT MAY NOT BE EXERCISED BY OR ON BEHALF OF ANY U.S. PERSON
              UNLESS REGISTERED UNDER THE ACT OR AN EXEMPTION FROM SUCH
              REGISTRATION IS AVAILABLE.
              
     (d)  Each Holder and JBO agrees, and each subsequent transferee described 
in paragraph (c)(ii) above shall agree, that it will give each person to whom it
transfers any Warrants or Warrant Shares notice of any restrictions on transfer 
thereof.

                                     -14-

 
     (e)   The restrictions set forth in Section 14(c) shall terminate and cease
to be effective with respect to any Warrants or Warrant Shares registered under 
the Securities Act or transferred pursuant to clause (A), (C) or (G) of Section 
14(c)(i). Whenever such restrictions shall so terminate the holder of such 
Warrants and/or Warrant Shares shall be entitled to receive from Issuer, without
expense (other than transfer taxes, if any), Warrant Certificates or 
certificates for such Warrant Shares not bearing the legend set forth in Section
14(c) at which time Issuer will rescind any transfer restrictions relating 
thereto.

     (f)   With a view to making available to each Holder and JBO and subsequent
holders of the Non Public Warrant Shares the benefits of certain rules and 
regulations of the Commission (including, without limitation, Rule 144 and Rule 
144A under the Securities Act) which may permit the sale of Non Public Warrant 
Shares without registration, Issuer agrees to take any and all such actions as 
may be required of it by applicable law, rule or regulation to make available to
each Holder and JBO and such subsequent holders such benefits, including without
limitation, to:

           (i)    make and keep public information available as those terms are 
understood and defined in Rule 144 under the Securities Act or any successor 
provision thereto;

           (ii)   so long as Rule 144A is available to any Holder or JBO and, 
such holders, make and keep available the information specified in Rule 
144A(d)(4) under the Securities Act or any successor provision thereto;

           (iii)  file with the Commission in a timely manner all reports and 
other documents required of Issuer under the Securities Act and the Exchange 
Act; and

           (iv)   so long as any Holder, JBO or any other holder owns any 
Warrants or Non Public Warrant Shares, furnish to each such holder forthwith 
upon request a written statement by Issuer as to its compliance with the 
information or reporting requirements of Rule 144 and Rule 144A or any successor
provision thereto, and of the Securities Act and the Exchange Act, a copy of the
most recent annual or quarterly report of Issuer filed with the Commission, and 
such other reports and documents of Issuer and other information in the 
possession of or reasonably obtainable by Issuer as such holder may reasonably 
request in availing itself of any rule or regulation of the Commission allowing 
such holder to sell any such securities without registration.

     (g)   Notwithstanding the foregoing, subject to the completeness and 
accuracy of each Purchaser's representations and warranties in the Purchase 
Agreement, upon the exercise of any Warrant by a person who is a non-U.S. 
Person, the Company shall instruct the Company's transfer agent to issue stock 
certificates with only the following restrictive legend:

           THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ISSUED TO A NON-
           U.S. PERSON AND ARE RESTRICTED AND MAY NOT BE SOLD OR TRANSFERRED
           EXCEPT IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT OF
           1933, AS AMENDED,

                                     -15-

 
           (THE "ACT"), OR AS PERMITTED UNDER THE ACT PURSUANT TO REGISTRATION 
           OR EXEMPTION THEREFROM.

The Company shall instruct the Company's transfer agent to issue stock 
certificates in the name of Purchaser (or its nominee (being a non-U.S. Person) 
or such non-U.S. Persons as may be designated by Purchaser prior to the Closing)
and in such denominations to be specified at exercise representing the number of
shares of Common Stock issuable upon such exercise, as applicable. If the stock 
certificates are issued to Purchaser upon exercise, the Company will after forty
(40) days, if requested in writing by the Purchaser and Purchaser submits the 
original stock certificate bearing the above legend for cancellation and 
reissue, issue a new stock certificate bearing no legend whatsoever; provided, 
however, that if the nominee or other non-U.S. Person in whose name a 
certificate or certificates for shares are requested to be restricted is other 
than Purchaser, or if there has been a regulatory development including, but not
limited to, an amendment or proposed amendment of Regulation S, or any 
"no-action" or interpretive guidance whether oral or written from the Securities
and Exchange Commission, which call into question the ability of the Company to 
issue to Purchaser the Warrant Shares without registration or a restrictive 
legend under the Securities Act, the Company may require prior to issuance of a 
certificate in the name of Purchaser or such other person, that it receive 
reasonable transfer documentation including an opinion of counsel in the form 
attached to the Purchase Agreement as Exhibit G that the issuance of 
certificates without restrictive legend and/or in such other name does not and 
will not cause a violation of the Securities Act; and provided further that if 
reasonable transfer documentation is provided, the Company warrants that no 
instructions other than these instructions will be given to the transfer agent 
and that the shares into which the Warrant are exercisable will not be subject 
to any transfer limitations other than those imposed by applicable securities 
laws. Nothing in this section 14(g), however, shall affect in any way 
Purchaser's or nominee's obligations and agreement to comply with all applicable
securities laws upon resale of the Securities.

     (h)   If, solely as a result of the Company's wrongful refusal to honor 
Purchaser's instruction in willful contravention of this Agreement, or wrongful 
refusal or failure to transfer or issue the Warrant Shares in willful 
contravention of this Agreement, any Purchaser suffers any loss, the Company 
shall reimburse Purchaser for such loss unless Purchaser shall have breached any
of its representations, warranties or covenants set forth in this Agreement or 
otherwise taken or omitted to take actions, which actions or omissions 
constitute gross negligence bad faith or willful misconduct.

     (i)   Each Holder and JBO agrees, and each subsequent transferee described 
in paragraph (c)(ii) above shall agree, that, upon exercise of Warrants it 
shall give (i) written certification that it is not a U.S. person and that the 
Warrant is not being exercised on behalf of a U.S. person or (ii) written 
opinion of counsel to the effect that the warrant and the securities delivered 
upon exercise thereof have been registered under the Act or are exempt from 
registration thereunder.

     Warrants may not be exercised within the United States and the Warrant 
Shares may not be delivered within the United States upon exercise, other than 
in offerings deemed to meet the definition of "offshore transaction" pursuant to
paragraph (i)(3) of Rule 902 under the Securities Act, unless registered under 
the Securities Act or an exemption from such registration is available.

advance notice, under the circumstances, of all meetings of the board of 
directors in accordance with the principles of Section 19 hereof unless such 
notice would be impracticable, in which case reasonable alternative notice will 
be given.

     The holders of the Warrants and/or Non Public Warrant Shares shall have the
right to specific performance by Issuer of the provisions of this Warrant 
Agreement. Issuer hereby irrevocably waives, to the extent that it may do so 
under applicable law, any defense based on the adequacy of a remedy at law which
may be asserted as a bar to the remedy of specific performance in any action 
brought against Issuer for specific performance of this Warrant Agreement by the
holders of the Warrants and/or Non Public Warrant Shares.
