Agreement and the Convertible Subordinated Debentures shall constitute
liquidated damages and not penalties. The parties further acknowledge that a
breach by either party of this Agreement or exhibits hereto, (a) the amount of
loss or damages likely to be incurred is incapable or is difficult to precisely
estimate, (b) the amounts specified in such agreements bear a reasonable
proportion and are not plainly or grossly disproportionate to the probable loss

Company to timely cause the registration of the Registrable Securities or to
deliver stock certificates upon any conversion, and (c) the parties are
sophisticated businesses and have been represented by sophisticated and able
legal and financial counsel and negotiated this Agreement at arm's length.
Notwithstanding any provision herein or in the agreements contemplated hereby,

counsel pursuant to this Agreement or the agreements contemplated hereby if such
failure results from Force Majeure.

      (b)   The Company,  at any time on up to 3 occasions during the 12 month
            period beginning on the date hereof,  provided that the average of
            the 5 consecutive  VWAPs immediately prior to such date is greater
            than  150%  of  the  Set  Price  of the  Convertible  Subordinated
            Debentures  issued at the First  Closing,  shall have the right to
            require the Investors to purchase,  severally and not jointly,  up
            to,  in  the  aggregate,   each  Investor's  Pro-Rata  portion  of

            aggregate,  for  all  3  occasions  shall  not  exceed  $3,000,000
            principal  amount and on no occasion shall a purchase  pursuant to
            this Section 1.4(b) be less than $1,000,000  principal  amount, in
            the  aggregate  and any election  hereunder by the Company must be
            to all of the Investors in such Pro-Rata amounts.

      (c)   Notwithstanding anything to the contrary herein, the aggregate
            purchase price of Convertible Debentures sold and purchased pursuant
            to this Section 1.4 shall not exceed $3,000,000, in the aggregate,
            such that if one party exercises its rights hereunder, the amount by
            which the other party may exercise its rights hereunder shall be
            reduced accordingly.

Agreement and the Warrants, and to issue the Convertible Subordinated
Debentures, the Conversion Shares, the Warrants and the Warrant Shares pursuant
to their respective terms, (b) the execution, issuance and delivery of this
Agreement, the Registration Rights Agreement, the Convertible Subordinated
Debentures and the Warrants by the Company and the consummation by it of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action and no further consent or authorization of the Company or its
Board of Directors or stockholders is required, and (c) this Agreement, the
Registration Rights Agreement, the Warrants and the Convertible Subordinated
Debentures have been duly executed and delivered by the Company and at the
Closing shall constitute valid and binding obligations of the Company
enforceable against the Company in accordance with their terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency, or similar
laws relating to, or affecting generally the enforcement of, creditors' rights
and remedies or by other equitable principles of general application. The
Company has duly and validly authorized and reserved for issuance shares of
Common Stock sufficient in number for the conversion of the Convertible
Subordinated Debentures and the exercise of the Warrants. The Company
understands and acknowledges the potentially dilutive effect to the Common Stock
of the issuance of the Conversion Shares and Warrant Shares. The Company further
acknowledges that its obligation to issue Conversion Shares and Warrant Shares
upon conversion of the Convertible Subordinated Debentures and Warrant Shares
upon exercise of the Warrants in accordance with this Agreement and the
Convertible Subordinated Debentures is absolute and unconditional regardless of
the dilutive effect that such issuance may have on the ownership interests of
other stockholders of the Company and notwithstanding the commencement of any
case under 11 U.S.C. ss. 101 et seq. (the "Bankruptcy Code"). The Company shall
not seek judicial relief from its obligations hereunder except pursuant to the
Bankruptcy Code. In the event the Company is a debtor under the Bankruptcy Code,
the Company hereby waives to the fullest extent permitted any rights to relief
it may have under 11 U.S.C. ss. 362 in respect of the conversion of the
Convertible Subordinated Debentures and the exercise of the Warrants. The
Company agrees, without cost or expense to the Investors, to take or consent to
any and all action necessary to effectuate relief under 11 U.S.C. ss. 362.

      Section 3.3 Capitalization. The authorized capital stock of the Company
consists of 100,000,000 shares of Common Stock of which 61,481,139 shares are
issued and outstanding, and 10,000,000 shares of preferred stock of which 1
share of Series A Preferred Stock is issued and outstanding. There are no
outstanding Capital Shares Equivalents nor any agreements or understandings
pursuant to which any Capital Shares Equivalents may become outstanding. The
Company is not a party to any agreement granting registration or anti-dilution
rights to any person with respect to any of its equity or debt securities. All
of the outstanding shares of Common Stock of the Company have been duly and
validly authorized and issued and are fully paid and non-assessable and have
been issued pursuant to valid exemptions from registration under the Securities
Act and all applicable state "blue sky" laws.

      Section 3.4 Common Stock/Listing of Shares. The Company has registered its
Common Stock pursuant to Section 12(b) or (g) of the Exchange Act and is in full
compliance with all reporting requirements of the Exchange Act, and the Company
is in compliance with all requirements for the continued listing or quotation of
its Common Stock, and such Common Stock is currently listed or quoted on the
Principal Market. The Company has not received any notice from any trading
market or exchange on which the Common stock has been listed to the effect that
the Company is not in compliance with the rules and regulations of such trading
market or exchange and that the Common Stock may be delisted from trading
thereon. Subject to compliance with Section 5.2 hereunder, the issuance and
delivery of the Convertible Subordinated Debentures, Conversion Shares, Warrants
and Warrant Shares does not violate any of the rules or regulations of such
trading market or exchange or require shareholder approval.

      Section 3.5 SEC Documents. The Company has made available to the Investors

SEC Documents complied in all material respects with the requirements of the
Exchange Act, and rules and regulations of the SEC promulgated thereunder and
the SEC Documents did not contain any untrue statement of a material fact or

statements) and fairly present in all material respects the financial position
of the Company as of the dates thereof and the results of operations and cash
flows for the periods then ended (subject, in the case of unaudited interim

any kind (whether accrued, absolute, contingent or otherwise, and whether due or
to become due) that would have been required to be reflected in, reserved
against or otherwise described in the financial statements or in the notes
thereto in accordance with GAAP, which was not fully reflected in, reserved
against or otherwise described in the financial statements or the notes thereto

applicable state securities law. When validly converted in accordance with the
terms of the Convertible Subordinated Debentures and the Warrants, the
Conversion Shares and Warrant Shares will be duly and validly issued, fully
paid, and non-assessable. Neither the sales of the Convertible Subordinated
Debentures, the Conversion Shares, the Warrants and Warrant Shares pursuant to,
nor the Company's performance of its obligations under, this Agreement, the
Registration Rights Agreement or the Convertible Subordinated Debentures and the
Warrants will (a) result in the creation or imposition by the Company of any
liens, charges, claims or other encumbrances upon the Convertible Subordinated
Debentures, the Warrants or the Conversion Shares and Warrant Shares or, except
as contemplated herein, any of the assets of the Company, or (b) entitle the
holders of Outstanding Capital Shares to preemptive or other rights to subscribe

Agreement by the Company and the consummation by the Company of the transactions
contemplated hereby, including without limitation the issuance of and payment of
interest upon the Convertible Subordinated Debentures, Warrants and the
Conversion Shares and Warrant Shares, do not and will not (a) result in a
violation of the Company's Articles of Incorporation or By-Laws or (b) conflict
with, or constitute a material default (or an event that with notice or lapse of
time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any material agreement,
indenture or instrument, or any "lock-up" or similar provision of any
underwriting or similar agreement to which the Company is a party, or (iii)
result in a violation of any federal, state or local law, rule, regulation,
order, judgment or decree (including federal and state securities laws and
regulations) applicable to the Company or by which any material property or
asset of the Company is bound or affected, nor is the Company otherwise in
violation of, conflict with or default under any of the foregoing (except in
each case for such conflicts, defaults, terminations, amendments, accelerations,
cancellations and violations as would not have, individually or in the
aggregate, a Material Adverse Effect) or which have been validly waived). The
business of the Company is not being conducted in violation of any law,
ordinance or regulation of any governmental entity, except for possible
violations that either singly or in the aggregate would not have a Material
Adverse Effect. The Company is not required under any federal, state or local

permit any of its directors, officers or affiliates directly or indirectly to
take, any action (including, without limitation, any offering or sale to any
Person of the Convertible Subordinated Debentures or shares of Common Stock) in
each case, so as to make unavailable the exemption from Securities Act

      Each Investor, severally and not jointly, covenants with the Company that:

      Section 4.1 Compliance with Law. The Investor's trading activities with
respect to the Conversion Shares and Warrant Shares will be in compliance with
all applicable state and federal securities laws, rules and regulations and
rules and regulations of the Principal Market on which the Company's Common
Stock is listed.

                                   ARTICLE V

                            COVENANTS OF THE COMPANY

      Section 5.1 Registration Rights. The Company shall cause the Registration
Rights Agreement to remain in full force and effect and the Company shall comply
in all material respects with the terms thereof.

      Section 5.2 Reservation of Common Stock. On any date hereafter, in the
event the number of Shares reserved, as to any Investor, is less than 200% of
the Conversion Shares necessary to convert all of such Investor's Convertible
Subordinated Debenture, based on the then applicable Mandatory Conversion Price
(as defined in the Convertible Subordinated Debenture) assuming conversion of
the entire outstanding principal amount of such Convertible Subordinated
Debenture at such time, and Warrant Shares to exercise all of such Investor's
Warrant (the "Trigger Amount"), then the Company shall have seven (7) calendar
days from such date to increase the number of shares reserved as to such
Investor above the Trigger Amount, unless to do so the Company must authorize
additional shares, in which case the Company shall have sixty (60) calendar days
from such date to increase the number of shares authorized and reserved as to
such Investor above the Trigger Amount.

      Section 5.3 Listing of Common Stock. The Company hereby agrees to maintain
the listing of the Common Stock on a Principal Market, and as soon as reasonably
practicable following the Closing to apply to list the Conversion Shares and the
Warrant Shares on the Principal Market and use reasonable best efforts to get
such shares listed. The Company further agrees, if the Company applies to have
the Common Stock traded on any other Principal Market, it will include in such
application the Conversion Shares and the Warrant Shares, and will take such
other action as is necessary or desirable in the opinion of the Investors to
cause the Conversion Shares and Warrant Shares to be listed on such other
Principal Market as promptly as possible. The Company will take all action to
continue the listing and trading of its Common Stock on a Principal Market and
will comply in all respects with the Company's reporting, filing and other
obligations under the bylaws or rules of the Principal Market.

      Section 5.4 Exchange Act Registration. The Company will cause its Common
Stock to continue to be registered under Section 12(b) or (g) of the Exchange

its reporting and filing obligations under said Act until the Investors have
disposed of all of their Registrable Securities.

new certificates free of a legend to an Investor and Company's counsel fails to
deliver such opinion to the Transfer Agent within 5 Trading Days from receipt by
Company's counsel of such a request from the Transfer Agent or the Investor's
broker-dealer, then the Company will pay such Investor, pro rata on a weekly
basis, as liquidated damages for such failure and not as a penalty, 5% per week
of the market value of the Common Stock which would be issuable upon conversion
of such Investor's Convertible Subordinated Debenture upon on any date of
determination for each week until such opinion is provided, notwithstanding the
fact that the Company has instructed the Transfer Agent to accept such an
opinion from such Investor's counsel provided, however, that no liquidated
damages shall be payable where the failure of counsel to provide such opinion is
caused by such counsel's having reasonable basis under securities laws, rules
and regulations for withholding such opinion..

      Section 5.6 Corporate Existence; Conflicting Agreements. The Company will
take all steps necessary to preserve and continue the corporate existence of the
Company. The Company shall not enter into any agreement, the terms of which
agreement would restrict or impair the right or ability of the Company to
perform any of its obligations under this Agreement or any of the other
agreements attached as exhibits hereto.

      Section 5.7 Issuance of Convertible Subordinated Debentures and Warrants.

issuance of the Conversion Shares upon conversion and Warrant Shares upon the
exercise of the Warrants of the Convertible Subordinated Debentures shall be
made in accordance with the provisions and requirements of Section 3(a)(9) of
the Securities Act of 1933, Section 4(2), Section 4(6) or Regulation D and any
applicable state securities law. The Company shall take all other necessary
commercially reasonable action and proceedings as may be required and permitted
by applicable law, rule and regulation, for the legal and valid issuance of the
Convertible Subordinated Debentures, the Warrants and the issuance of the
Conversion Shares upon conversion and Warrants shares upon exercise to the
Investors. The Company shall make any necessary SEC and "blue sky" filings as
may be required to be made by the Company in connection with the sale of the
Securities to the Investors, and shall provide a copy thereof to the Investors
promptly after such filing.

      Section 5.8 Mandatory Redemption. Subject to the terms and conditions set
forth in the Convertible Subordinated Debentures, commencing on April 1, 2002
and continuing on the first Trading Day after each 30 calendar day period
thereafter (each such date, a "Mandatory Redemption Date" and such redemption, a
"Mandatory Redemption"), the Company shall redeem, in the aggregate, the greater
of (i) $500,000 of the then outstanding principal balance of the Convertible
Subordinated Debentures, and (ii) an amount equal to the then outstanding
principal balance of the Convertible Subordinated Debentures divided by the
number of full months remaining until the Maturity Dates of said debentures
(such amount so redeemed, the "Mandatory Redemption Amount").

      Section 5.9 Pro-Rata Redemption. Upon any redemption of any of the
Convertible Subordinated Debentures, the Company shall offer such redemption
Pro-Rata Adjusted among all Investors at such time, except that, a redemption
pursuant to Section 5.8 shall be Pro-Rata, subject to adjustment upward in the
event an Investor no longer holds any Convertible Subordinated Debentures.

      Section 5.10 Limitation on Future Financing. The Company agrees that,
until 3 calendar months following the Effective Date relating to the securities
purchased at the First and Second Closings, it will not (i) enter into any other
sale of its Capital Shares or any Capital Shares Equivalents at a discount to
the then or now current market price (or which may be converted, exchanged,
reset or otherwise at a future discount to market price that could be lower than
the current market price), or (ii) sell or exercise any rights to sell
(including any action which would trigger the commencement of a pricing period)
Common Stock or other securities to Crescent International Ltd. ("Crescent")
pursuant to the Stock Purchase Agreement between the Company and Crescent, dated
as of August 20, 2001. The foregoing shall not prevent or limit the Company from
granting equity incentive awards pursuant to equity incentive and stock option
plans approved by the Company's Board of Directors or selling securities
purchased pursuant to the Company's Employee Stock Purchase Plan or engaging in
any sale of securities (i) pursuant to the exercise of options granted or to be
granted under an employee benefit plan which plan has been approved by the
Company's Board of Directors, (ii) pursuant to any compensatory plan for an
employee or consultant, (iii) in connection with a strategic partnership or
other business transaction, the principal purpose of which is not simply to
raise money, (iv) in a registered public offering by the Company which is
underwritten by one or more established investment banks (not including an
equity line type financing), or (v) with the prior written approval of a
majority in interest of the Investors, which will not be unreasonably withheld.

                                   ARTICLE VI

                            SURVIVAL; INDEMNIFICATION

      Section 6.1 Survival. The representations, warranties and covenants made
by each of the Company and each Investor in this Agreement, the annexes,
schedules and exhibits hereto and in each instrument, agreement and certificate
entered into and delivered by them pursuant to this Agreement, shall survive
each Closing and the consummation of the transactions contemplated hereby until
the earlier of (i) the date on which all Investors hold, or have the right to
convert or exercise securities into, fewer than 250,000 shares of Common Stock
pursuant to this Agreement and the transactions contemplated hereby, and (ii)
the third anniversary of the last Closing pursuant to this Agreement. In the
event of a breach or violation of any of such representations, warranties or
covenants, the party to whom such representations, warranties or covenants have
been made shall have all rights and remedies for such breach or violation
available to it under the provisions of this Agreement, irrespective of any
investigation made by or on behalf of such party on or prior to a Closing Date,
unless such party had actual knowledge of such breach or violation prior to such
Closing Date.

      Section 6.2 Indemnity.

      (a)   The Company hereby agrees to indemnify and hold harmless the
            Investors, their respective Affiliates and their respective
            officers, directors, partners and members (collectively, the
            "Investor Indemnitees"), from and against any and all Damages, and
            agrees to reimburse the Investor Indemnitees for all reasonable
            out-of-pocket expenses (including the reasonable fees and expenses
            of legal counsel), in each case promptly as incurred by the Investor
            Indemnitees and to the extent arising out of or in connection with:

            (i)   any material misrepresentation, omission of fact or breach of
                  any of the Company's representations or warranties contained
                  in this Agreement, the annexes, schedules or exhibits hereto
                  or any instrument, agreement or certificate entered into or
                  delivered by the Company pursuant to this Agreement; or

            (ii)  any failure by the Company to perform in any material respect
                  any of its material covenants, agreements, undertakings or
                  obligations set forth in this Agreement, the annexes,
                  schedules or exhibits hereto or any instrument, agreement or
                  certificate entered into or delivered by the Company pursuant
                  to this Agreement; or

            (iii) any action instituted against the Investors, or any of them or
                  their respective Affiliates, by any stockholder of the Company
                  who is not an Affiliate of an Investor, with respect to any of
                  the transactions contemplated by this Agreement.

      (b)   Each Investor, severally and not jointly, hereby agrees to indemnify
            and hold harmless the Company, its Affiliates and their respective
            officers, directors, partners and members (collectively, the
            "Company Indemnitees"), from and against any and all Damages, and
            agrees to reimburse the Company Indemnitees for all reasonable
            out-of-pocket expenses (including the reasonable fees and expenses
            of legal counsel), in each case promptly as incurred by the Company
            Indemnitees and to the extent arising out of or in connection with
            any misrepresentation, omission of fact, or breach of any of the
            Investor's representations or warranties contained in this
            Agreement, the annexes, schedules or exhibits hereto or any
            instrument, agreement or certificate entered into or delivered by
            the Investor pursuant to this Agreement. Notwithstanding anything to
            the contrary herein, an Investor shall be liable under this Section
            6.2(b) for only that amount as does not exceed the net proceeds
            received by such Investor as a result of the sale of Registrable
            Securities pursuant to the Registration Statements.

      Section 6.3 Notice. Promptly after receipt by any party hereto seeking
indemnification pursuant to Section 6.2 (an "Indemnified Party") of written
notice of any investigation, claim, proceeding or other action in respect of
which indemnification is being sought (each, a "Claim"), the Indemnified Party
promptly shall notify the party from whom indemnification pursuant to Section
6.2 is being sought (the "Indemnifying Party") of the commencement thereof; but
the omission to so notify the Indemnifying Party shall not relieve it from any
liability that it otherwise may have to the Indemnified Party, except to the
extent that the Indemnifying Party is actually prejudiced by such omission or
delay. In connection with any Claim as to which both the Indemnifying Party and
the Indemnified Party are parties, the Indemnifying Party shall be entitled to
assume the defense thereof. Notwithstanding the assumption of the defense of any
Claim by the Indemnifying Party, the Indemnified Party shall have the right to
employ separate legal counsel and to participate in the defense of such Claim,
and the Indemnifying Party shall bear the reasonable fees, out-of-pocket costs
and expenses of such separate legal counsel to the Indemnified Party if (and
only if): (a) the Indemnifying Party shall have agreed to pay such fees,
out-of-pocket costs and expenses, (b) the Indemnified Party reasonably shall
have concluded that representation of the Indemnified Party and the Indemnifying
Party by the same legal counsel would not be appropriate due to actual or, as
reasonably determined by legal counsel to the Indemnified Party, potentially
differing interests between such parties in the conduct of the defense of such
Claim, or if there may be legal defenses available to the Indemnified Party that
are in addition to or disparate from those available to the Indemnifying Party,
or (c) the Indemnifying Party shall have failed to employ legal counsel
reasonably satisfactory to the Indemnified Party within a reasonable period of
time after notice of the commencement of such Claim. If the Indemnified Party
employs separate legal counsel in circumstances other than as described in
clauses (a), (b) or (c) above, the fees, costs and expenses of such legal
counsel shall be borne exclusively by the Indemnified Party. Except as provided
above, the Indemnifying Party shall not, in connection with any Claim in the
same jurisdiction, be liable for the fees and expenses of more than one firm of
legal counsel for the Indemnified Party (together with appropriate local
counsel). The Indemnifying Party shall not, without the prior written consent of
the Indemnified Party (which consent shall not unreasonably be withheld), settle
or compromise any Claim or consent to the entry of any judgment that does not
include an unconditional release of the Indemnified Party from all liabilities
with respect to such Claim or judgment.

      All fees and expenses of the Indemnified Party (including reasonable costs
of defense and investigation in a manner not inconsistent with this Section and
all reasonable attorneys' fees and expenses) shall be paid to the Indemnified
Party, as incurred, within ten (10) Trading Days of written notice thereof to
the Indemnifying Party (regardless of whether it is ultimately determined that
an indemnified party is not entitled to indemnification hereunder; provided,
that the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder).

      Section 6.4 Direct Claims. In the event one party hereunder should have a
claim for indemnification that does not involve a claim or demand being asserted
by a third party, the Indemnified Party promptly shall deliver notice of such
claim to the Indemnifying Party. If the Indemnifying Party disputes the claim,
such dispute shall be resolved by mutual agreement of the Indemnified Party and
the Indemnifying Party or in accordance with Article IX. Judgment upon any award
rendered by any arbitrators may be entered in any court having competent
jurisdiction thereof.

                                  ARTICLE VII

                              DUE DILIGENCE REVIEW

      Section 7.1 Non-Disclosure of Non-Public Information.

      (a)   The Company shall not disclose material non-public information to
            the Investors, advisors to or representatives of the Investors
            unless prior to disclosure of such information the Company
            identifies such information as being non-public information and
            provides the Investors, such advisors and representatives with the
            opportunity to accept or refuse to accept such non-public
            information for review. Other than disclosure of a portion of any
            comment letters received from the SEC staff with respect to the
            Registration Statements that pertain specifically to this
            transaction or the selling shareholders and their plan of
            distribution, the Company may, as a condition to disclosing any
            non-public information hereunder, require the Investors' advisors
            and representatives to enter into a confidentiality agreement in
            form and content reasonably satisfactory to the Company and the
            Investors.

      (b)   The Company will promptly notify the advisors and representatives of
            the Investors and, if any, underwriters, of any event or the
            existence of any circumstance (without any obligation to disclose
            the specific event or circumstance) of which it becomes aware,
            constituting material non-public information (whether or not
            requested of the Company specifically or generally during the course
            of due diligence by such persons or entities), which, if not
            disclosed in the prospectus included in the Registration Statements,
            would cause such prospectus to include a material misstatement or to
            omit a material fact required to be stated therein in order to make
            the statements, therein in light of the circumstances in which they
            were made, not misleading. Nothing contained in this Section 7.1
            shall be construed to mean that such persons or entities other than
            the Investors (without the written consent of the Investors prior to
            disclosure of such information as set forth in Section 7.1(a)) may
            not obtain non-public information in the course of conducting due
            diligence in accordance with the terms of this Agreement and nothing
            herein shall prevent any such persons or entities from notifying the
            Company of their opinion that based on such due diligence by such
            persons or entities, that the Registration Statements contains an
            untrue statement of a material fact or omits a material fact
            required to be stated in the Registration Statements or necessary to
            make the statements contained therein, in light of the circumstances
            in which they were made, not misleading.

                                  ARTICLE VIII

                      LEGENDS; TRANSFER AGENT INSTRUCTIONS

      Section 8.1 Legends. Unless otherwise provided below, each certificate
representing Registrable Securities will bear the following legend or equivalent
(the "Legend"):

      THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE U.S. SECURITIES ACT, AS AMENDED, OR ANY OTHER APPLICABLE
      SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN EXEMPTION FROM
      THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH OTHER
      SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION
      HEREIN MAY BE SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, OR
      OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
      STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A TRANSACTION THAT IS
      EXEMPT FROM SUCH REGISTRATION.

      Section 8.2 Removal of Legends. During any periods following the Effective
Date that a Registration Statement is effective, or otherwise in accordance with
the Registration Rights Agreement, the shares of Common Stock issued hereunder
and registered thereunder shall not bear any restrictive legend and shall
otherwise be freely transferable. In the event the Company fails to deliver or
cause its transfer agent to deliver such shares free of any legends, or remove
any such legend from already issued shares of Common Stock, the Investor shall
be entitled to, in addition to any other rights hereunder or in the Convertible
Subordinated Debentures, the liquidated damages described in Section 4(c)(iii)
of the Convertible Subordinated Debentures. In the event a legend is so removed,
the Investor agrees to sell the Shares represented by an unlegended certificate
in accordance with the plan of distribution set forth in the applicable
Registration Statement.

      Section 8.3 Transfer Agent Instructions. Upon the execution and delivery
hereof, the Company is issuing to the transfer agent for its Common Stock (and
to any substitute or replacement transfer agent for its Common Stock upon the
Company's appointment of any such substitute or replacement transfer agent)
instructions substantially in the form of Exhibit F hereto. Such instructions
shall be irrevocable by the Company from and after the date hereof or from and
after the issuance thereof to any such substitute or replacement transfer agent,
as the case may be. The Company warrants that no instruction relating to the
Registrable Securities other than the irrevocable transfer agent instructions
referred to in this section shall be given by the Company to the Company's
transfer agent. After the Effective Date, in lieu of delivering physical
certificates representing the Common Stock registered under the applicable
Registration Statement issuable upon the conversion of, or in lieu of interest
payments on, the Convertible Subordinated Debentures, the Company shall cause
its transfer agent to electronically transmit the Conversion Shares by crediting
the account of the Investor's prime broker with the Depository Trust Company
("DTC") Fast Automated Securities Transfer program through its Deposit
Withdrawal Agent Commission ("DWAC") system no later than the applicable date of
delivery.

      Section 8.4 No Other Legend or Stock Transfer Restrictions. No legend
other than the one specified in Section 8.1 has been or shall be placed on the
share certificates representing the Registrable Securities and no instructions
or "stop transfer orders," "stock transfer restrictions," or other restrictions
have been or shall be given to the Company's transfer agent with respect thereto
other than as expressly set forth in this Article VIII.

      Section 8.5 Investors' Compliance. Nothing in this Article shall affect in
any way each Investor's obligations to comply with all applicable securities
laws upon resale of the Common Stock.

      Section 8.6 Rule 144. Subject to the applicable securities laws, the
Company acknowledges and agrees that, for the purpose of calculating the holding
period of the Shares under Rule 144, the Conversion Shares and the Warrant
Shares shall be deemed to have been acquired on the applicable Closing Date.

                                   ARTICLE IX

                                  CHOICE OF LAW

      Section 9.1 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made in New York by persons domiciled in New York City and without
regard to its principles of conflicts of laws. The Company and each of the
Investors agree to submit themselves exclusively to the in personam jurisdiction
of the state and federal courts situated within the Southern District of the
State of New York with regard to any controversy arising out of or relating to
this Agreement. Any party shall be entitled to obtain injunctive relief from a
court in any case where such relief is available, and the prevailing party in
such injunctive action shall be entitled to its reasonable attorneys' fees in
connection therewith. The non-prevailing party to any dispute hereunder shall
pay the expenses of the prevailing party, including reasonable attorneys' fees,
in connection with any such dispute.

      Section 9.2 Specific Enforcement. The Company acknowledges and agrees that
irreparable damage would occur in the event that any of the provisions of this
Agreement or any of the exhibits hereto were not performed in accordance with
their specific terms or were otherwise breached, notwithstanding any reasons the
Company may have to the contrary in the future, including claims of solvency or
that the Investor is not put at risk absent performance by the Company. It is
accordingly agreed that the Investors shall be entitled to an injunction or
injunctions to prevent or cure breaches of the provisions of this Agreement and
to enforce specifically the terms and provisions hereof or thereof, this being
in addition to any other remedy to which any of them may be entitled by law or
equity. The prevailing party in such injunctive action shall be entitled to its
reasonable attorneys' fees in connection with any such specific performance.

                                   ARTICLE X

                                   ASSIGNMENT

      Section 10.1 Assignment. Neither this Agreement nor any rights of the
Company hereunder may be assigned by the Company to any other person. The
Investor's shall not assign this Agreement without the consent of the Company,
which consent shall not be unreasonably withheld. The provisions of this
Agreement shall inure to the benefit of, and be enforceable by, any permitted
transferee of any of the Convertible Subordinated Debentures and Warrants
purchased or acquired by any Investor hereunder with respect to the Convertible
Subordinated Debentures and Warrants held by such person. Notwithstanding
anything to the contrary herein, in no event shall an Investor assign this
Agreement, their Convertible Subordinated Debentures or their Warrants to any
persons, entities or companies that, in the reasonable judgment of the Company,
are in direct competition with the Company, including but not limited to,
persons, entities or companies in the telecommunications industry, data
communications industry or the business of manufacturing optical fiber or
preform.

      Section 12.1 Counterparts/Facsimile/Amendments. This Agreement may be
executed in multiple counterparts, each of which may be executed by less than

                      5% CONVERTIBLE SUBORDINATED DEBENTURE

              DUE ON THE SECOND ANNIVERSARY OF THE DATE OF ISSUANCE

      THIS DEBENTURE is one of a series of duly authorized and issued debentures
of FiberCore, Inc., a Nevada corporation, having a principal place of business
at 253 Worcester Road, Charlton, Massachusetts 01507 (the "Company"), designated
as its 5% Convertible Subordinated Debentures (the "Debentures" and this
debenture, this "Debenture"), issued pursuant to the Convertible Subordinated
Debentures and Warrants Purchase Agreement, as amended from time to time,
originally dated January 14, 2002 among the Company and the investors signatory
thereto (the "Purchase Agreement"). CAPITALIZED TERMS NOT DEFINED IN SECTION 19
OR ELSEWHERE IN THIS DEBENTURE SHALL HAVE THE MEANINGS ASCRIBED TO THEM IN THE
PURCHASE AGREEMENT.

      FOR VALUE RECEIVED, the Company promises to pay to ______________, or its
registered assigns (the "Holder"), the principal sum of _____________ Dollars
($______________), or such lesser amount reflecting the principal balance
then-outstanding, on the second anniversary of the issuance hereof or such
earlier date as this Debenture is required or permitted to be repaid as provided
hereunder (the "Maturity Date") and to pay interest to the Holder on the
aggregate unconverted and then outstanding principal amount of this Debenture at
the rate of 5% per annum, payable semi-annually, in cash or shares of Common
Stock as set forth herein. On each conversion of this Debenture, the Company and
the Holder shall agree in writing as to the unconverted principal amount
then-outstanding following each such conversion. Subject to the terms and
conditions herein, the decision whether to pay interest hereunder in registered
shares of Common Stock or cash shall be at the discretion of the Company.
Semi-annual interest payments shall be due and payable on January __ and July __
of each year, commencing with July __, 2002. Not less than 10 Trading Days
preceding the month in which a semi-annual interest payment is due, the Company
shall provide the Holder with written notice of its election to pay interest
payments due hereunder either in cash or registered shares of Common Stock (the
Company may indicate in such notice that the election contained in such notice
shall continue for later periods until revised). Failure to timely provide such
written notice shall be deemed an election by the Company to pay interest in
cash. Payment in shares shall be based on the average of the VWAPs during the 5
Trading Days immediately prior to the interest payment date and otherwise
subject to conversions pursuant to Section 4. Failure to timely provide such
written notice shall be deemed an election by the Company to pay interest in
cash, except that, if the Company shall not have delivered any cash due as
payment of interest hereon by the third Trading Day after the date such interest
is due, the Holder may, by notice to the Company, require the Company to issue
shares of Common Stock in lieu of such interest payment, except that for such
purpose the conversion price applicable thereto shall be the lesser of (A) the
Mandatory Conversion Price on the Conversion Date, and (B) the Mandatory
Conversion Price on the date of the Holder's demand. Interest shall be
calculated on the basis of a 360-day year and shall accrue daily commencing on
the Original Issue Date until payment in full of the principal sum, together
with all accrued and unpaid interest and other amounts which may become due
hereunder, has been made. Interest hereunder will be paid to the Person in whose
name this Debenture is registered on the records of the Company regarding
registration and transfers of Debentures (the "Debenture Register"). All overdue
accrued and unpaid interest to be paid in cash hereunder shall entail a late fee
at the rate of 18% per annum (or such lower maximum amount of interest permitted
to be charged under applicable law) (the "Late Fee") (to accrue daily, from the
date such interest is due hereunder through and including the date of payment),
payable in cash.

      This Debenture is subject to the following additional provisions:

      Section 1. This Debenture is exchangeable for an equal aggregate principal
amount of Debentures of different authorized denominations, as requested by the
Holder surrendering the same. No service charge will be made for such
registration of transfer or exchange.

      Section 2. This Debenture has been issued subject to certain investment
representations of the original Holder set forth in the Purchase Agreement and
may be transferred or exchanged only in compliance with the Purchase Agreement
and the legend set forth on the face of this Debenture. Prior to due presentment
to the Company 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 Debenture Register as the owner hereof for the purpose of receiving payment
as herein provided and for all other purposes, whether or not this Debenture is
overdue, and neither the Company nor any such agent shall be affected by notice
to the contrary.

      Section 3.  Events of Default.

            (a) "Event of Default", wherever used herein, means any one of the
      following events (whatever the reason and whether it shall be voluntary or
      involuntary or effected by operation of law or pursuant to any judgment,
      decree or order of any court, or any order, rule or regulation of any
      administrative or governmental body):

                  (i) any default in the payment of the principal of, or
            interest on, any Debentures, in the case of principal, as and when
            the principal shall become due and payable and in the case of
            interest, if such default remains uncured for 5 business days; or

                  (ii) any of the representations or warranties made by the
            Company herein, in the Purchase Agreement, the Registration Rights
            Agreement, or in any agreement, certificate or financial statements
            heretofore or hereafter furnished by the Company in connection with
            the execution and delivery of this Debenture or the Purchase
            Agreement shall be false or misleading, in light of the
            circumstances when made, in any material respect at the time made;
            or

                  (iii) the Company (a) fails to issue Conversion Shares to the
            Holder or to cause its Transfer Agent to issue Conversion Shares,

            transfer any certificate for Conversion Shares issued to the Holder
            as and when required by this Debenture or the Registration Rights
            Agreement, and such transfer is otherwise lawful, or (c) fails to
            remove any restrictive legend or to cause its Transfer Agent to
            transfer any certificate or any Conversion Shares issued to the
            Holder as and when required by this Debenture, the Purchase
            Agreement or the Registration Rights Agreement and such legend
            removal is otherwise lawful, and any such failure described in
            subclauses (a), (b) or (c) shall continue uncured for 7 business
            days; or

                  (iv) the Company shall fail to perform or observe, in any
            material respect, any other covenant, term, provision, condition,
            agreement or obligation of the Company under the Purchase Agreement,
            the Registration Rights Agreement or this Debenture including but
            not limited to the payments of interest (other than semi-annual
            interest payments), liquidated damages and Late Fees, provided the
            Holder has provided the Company notice and an opportunity to cure
            within 10 Trading Days of any such event of default under this
            Section 3(a)(iv); or

                  (v) any governmental agencies or any court of competent
            jurisdiction at the instance of any governmental agency shall assume
            custody or control of the whole or any substantial portion of the
            properties or assets of the Company and such action shall not be
            dismissed within 60 days thereafter; or

                  (vi) any money judgment, writ or warrant of attachment, or
            similar process in excess of $100,000 in the aggregate shall be
            entered or filed against the Company or any of its properties or
            other assets and shall remain unpaid, unvacated, unbonded or
            unstayed for a period of 60 days or in any event later than 5 days
            prior to the date of any proposed sale thereunder; or

                  (vii) the Registration Statement is not declared effective by
            the SEC within 120 days from the Closing at which this Debenture was
            issued; or

                  (viii) the Company or any of its respective subsidiaries shall
            commence, a case under any applicable bankruptcy or insolvency laws
            as now or hereafter in effect or any successor thereto, or the
            Company or any of its respective subsidiaries commences any other
            proceeding under any reorganization, arrangement, adjustment of
            debt, relief of debtors, dissolution, insolvency or liquidation or
            similar law of any jurisdiction whether now or hereafter in effect
            relating to the Company or any of its respective subsidiaries or
            there is commenced against the Company or any of its respective
            subsidiaries any such bankruptcy, insolvency or other proceeding
            which remains undismissed for a period of 60 days; or the Company or
            any of its respective subsidiaries is adjudicated insolvent or
            bankrupt; or any order of relief or other order approving any such
            case or proceeding is entered; or the Company or any of its
            respective subsidiaries suffers any appointment of any custodian or
            the like for it or any substantial part of its property which
            continues undischarged or unstayed for a period of 60 days; or the
            Company or any of its subsidiaries makes a general assignment for
            the benefit of creditors; or the Company or any of its subsidiaries
            shall fail to pay, or shall state that it is unable to pay, or shall
            be unable to pay, its debts generally as they become due; or the
            Company or any of its subsidiaries shall call a meeting of its
            creditors with a view to arranging a composition, adjustment or
            restructuring of its debts in contemplation of filing a prepackaged
            plan of reorganization under Chapter 11 of the United States
            Bankruptcy Code; or the Company or any of its subsidiaries shall by
            any act or failure to act expressly indicate its consent to,
            approval of or acquiescence in any of the foregoing; or any
            corporate or other action is taken by the Company or any of its
            subsidiaries for the purpose of effecting any of the foregoing; or

                  (ix) the Company (or any subsidiary thereof if guaranteed by
            the Company) shall default (unless such default is the subject of a
            bona fide dispute and the Company has set aside adequate reserves)
            in any of its obligations under any other Debenture or any mortgage,
            credit agreement or other facility, indenture agreement, factoring
            agreement or other instrument under which there may be issued, or by
            which there may be secured or evidenced any indebtedness for
            borrowed money or money due under any long term leasing or factoring
            arrangement of the Company in an amount exceeding an aggregate of
            $400,000, unless waived, extended or cured within 10 business days,
            whether such indebtedness now exists or shall hereafter be created
            and such default shall result in such indebtedness becoming or being
            declared due and payable prior to the date on which it would
            otherwise become due and payable; or

                  (x) the Common Stock shall be delisted from the Principal
            Market or suspended from trading on the Principal Market without
            resuming trading and/or being relisted or thereon or listed on
            another Principal Market or having such suspension lifted, in either
            case, for more than either 3 consecutive Trading Days or 5 Trading
            Days in the aggregate during any 12 month period (which need not be
            consecutive Trading Days); or

                  (xi) the Company shall have suspended the Holder's conversion
            rights for more than four (4) Trading Days in the aggregate during
            any 12 month period (provided, however, that this Event of Default
            shall not be deemed to grant the Company any right to any such
            suspensions); or

                  (xii) if the effectiveness of the Registration Statement
            lapses for any reason or the Holder shall not be permitted to resell
            Registrable Securities (as defined in the Registration Rights
            Agreement) under the Registration Statement, in either case, for
            more than 30 Trading Days, in the aggregate, during any 12 month
            period.

            (b) During the time that any portion of this Debenture remains
      outstanding, if any Event of Default occurs and is continuing, unless such
      Event of Default shall have been waived in writing by the Holder (which
      waiver shall not be deemed to be a waiver of any subsequent default) at
      the option of the Holder and in the Holder's sole discretion, the Holder
      may consider this Debenture immediately due and payable in cash, without
      presentment, demand, protest or notice of any kind, 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. The
      aggregate amount payable upon an Event of Default shall be equal to the
      Event of Default Amount. Interest shall accrue on the amount due hereunder
      from the seventh day after such amount is due (being the date of an Event
      of Default) through the date of redemption in full thereof at the rate of
      18% per annum (or such lesser maximum amount that is permitted to be paid
      by applicable law), to accrue daily from the date such payment is due
      hereunder through and including the date of payment. All Debentures and
      Conversion Shares for which the full redemption price hereunder shall have
      been paid in accordance herewith shall promptly be surrendered to or as
      directed by the Company. The Holder need not provide and the Company
      hereby waives any presentment, demand, protest or other notice of any
      kind, and the Holder may immediately and without expiration of any grace
      period enforce any and all of its rights and remedies hereunder and all
      other remedies available to it under applicable law. Such declaration may
      be rescinded and annulled by Holder at any time prior to payment
      hereunder. No such rescission or annulment shall affect any subsequent
      Event of Default or impair any right consequent thereon.

      Section 4.  Conversion.

            (a)   Conversion at Option of Holder.

                  (i) At the option of the Holder, this Debenture shall be
            convertible into Conversion Shares, in whole or in part, at any time
            and from time to time, after the Original Issue Date (subject to the
            limitations on conversion set forth in Section 4). The number of
            Conversion Shares issuable hereunder shall be determined by dividing
            (1) the outstanding principal amount of this Debenture to be
            converted plus all accrued and unpaid interest on such Debenture by
            (2) $____ (110% of the average of the VWAPs during the 5 consecutive
            Trading Days immediately prior to the Original Issue Date)(subject
            to adjustments herein)(the "Set Price"), provided that if the
            Company has not elected to pay the accrued and unpaid interest on
            such Debenture in shares of Common Stock within the prescribed time
            period, then the number of shares shall be determined by dividing
            the outstanding principal amount of this Debenture to be converted
            by the Set Price; provided further, that notwithstanding any
            provision herein, the Company may elect to pay interest in cash in
            the event of a conversion pursuant to this Section 4.

                  (ii)  Notwithstanding  anything  to the  contrary  contained
            herein, if on any Conversion Date:

                        (A) the Common Stock is not listed or quoted on a
                  Principal Market;

                        (B) the Company has failed to timely satisfy its
                  conversion obligations hereunder with respect to Debentures
                  submitted for conversion on such conversion date; or

                        (C) the issuance of such shares of Common Stock would
                  result in a violation of Sections 4(d)(ii) herein.

                  then, at the option of the Holder, the Company, in lieu of
            delivering Conversion Shares, shall deliver, within 4 Trading Days
            of each applicable Conversion Date, an amount in cash equal to the
            product of the number of Conversion Shares otherwise deliverable to
            the Holder in connection with such Conversion Date and the highest
            VWAP during the period commencing on the Conversion Date and ending
            on the Trading Day prior to the date such payment is made.

            (b) [Intentionally left Blank]

            (c) Conversion Procedure.

                  (i) CONVERSION NOTICES. The Holder shall effect conversions by
            surrendering, if applicable, this Debenture (but only if the Holder
            is converting the entire outstanding principal amount of this
            Debenture), together with the form of conversion notice attached
            hereto (a "Conversion Notice") to the Company and the Company's
            transfer agent. Each Conversion Notice shall specify the principal
            amount of this Debenture to be converted, the applicable conversion
            price and the date on which such conversion is to be effected, which
            date may not be prior to the date such Conversion Notice is deemed
            to have been delivered hereunder (a "Conversion Date"). If the
            Holder is converting less than all of the principal amount
            represented by this Debenture, the Holder shall convert at least
            $100,000 in principal amount of this Debenture. The Holder shall not
            deliver to the Company more than 4 Conversion Notices per calendar
            month, provided, however, in the event that (A) the Holder delivers
            a Conversion Notice which is otherwise not permitted hereunder, and
            (B) on or prior to 5 pm ET on the Trading Day following the date
            such notice is delivered, the Company fails to notify the Holder
            that it does not intend to honor such Conversion Notice pursuant to
            this provision, the Company shall be required to honor such
            Conversion Notice. If no Conversion Date is specified in a
            Conversion Notice, the Conversion Date shall be the date that such
            Conversion Notice is deemed delivered hereunder. Unless otherwise
            provided for by the terms hereunder, each Conversion Notice, once
            given, shall be irrevocable. If the Holder is converting less than
            all of the principal amount represented by this Debenture, it shall
            not be required to surrender this Debenture but may exercise its
            right to convert solely by the delivery of a Conversion Notice. If a
            conversion hereunder cannot be effected in full for any reason, the
            Company shall honor such conversion to the extent permissible
            hereunder. At anytime the Holder may elect, upon delivery of this
            Debenture to the Company, to receive a new Debenture for such
            principal amount as has not been converted.

                  (ii) DELIVERY OF CONVERSION SHARES. Not later than 4 Trading
            Days after any Conversion Date, the Company will deliver to the
            Holder, at an address in the United States supplied by the Holder,
            (A) a certificate or certificates which shall be free of restrictive
            legends and trading restrictions (other than those permitted by the
            Purchase Agreement) representing the number of shares of Common
            Stock being acquired upon the conversion of this Debenture (subject
            to the limitations set forth in Section 4(d) hereof), (B) if
            applicable, a new Debenture in a principal amount equal to the
            principal amount of Debentures not converted (if the Holder elects
            to surrender this Debenture and a principal amount remains
            outstanding after conversion), and (C) a bank wire or a bank or
            certified check in the amount of accrued and unpaid interest (if the
            Company has timely elected or is required to pay accrued interest in
            cash). The Company shall, upon request of the Holder, if available,
            use its best efforts to deliver any certificate or certificates
            required to be delivered by the Company under this Section
            electronically through the Depository Trust Corporation or another
            established clearing corporation performing similar functions.

                  (iii) FAILURE TO DELIVER CONVERSION SHARES IN A TIMELY MANNER.
            If the Company fails for any reason to deliver to the Holder such
            certificate or certificates by the 5th Trading Day after the
            Conversion Date in accordance with Section 4(c)(ii), including, (in
            the event that shares are to be delivered in certificated form) but
            not limited to, the obligation of the Company to deliver such shares
            without any restrictive legend, the Company shall pay to such
            Holder, in cash, as liquidated damages and not as a penalty, for
            each $5,000 of principal amount being converted, $25 per Trading Day
            (increasing to $50 per Trading Day after 3 Trading Days and
            increasing to $100 per Trading Day 6 Trading Days after such damages
            begin to accrue) after such 5th Trading Day until such certificates
            are delivered; provided, however, in the event the Holder elects to
            rescind a conversion notice, liquidated damages shall accrue only up
            to the date of such rescission notice but not thereafter with
            respect to such rescinded conversion. If in the case of any
            Conversion Notice such certificate or certificates are not delivered
            to or as directed by the applicable Holder by the 5th Trading Day
            after a Conversion Date, the Holder shall be entitled by written
            notice to the Company at any time on or before its receipt of such
            certificate or certificates thereafter, to rescind such conversion,
            in which event the Company shall immediately return the certificates
            representing the principal amount of Debentures tendered for
            conversion. Nothing herein shall limit a Holder's right to pursue
            actual damages or declare an Event of Default pursuant to Section 3
            herein for the Company's failure to deliver certificates
            representing shares of Common Stock upon conversion within the
            period specified herein and such Holder shall have the right to
            pursue all remedies available to it at law or in equity including,
            without limitation, a decree of specific performance and/or
            injunctive relief. The exercise of any such rights shall not
            prohibit the Holders from seeking to enforce damages pursuant to any
            other Section hereof or under applicable law. Further, if the
            Company shall not have delivered any cash due as payment of interest
            hereon by the fifth Trading Day after the Conversion Date, the
            Holder may, by notice to the Company, require the Company to issue
            shares of Common Stock pursuant to Section 4(a), except that for
            such purpose the conversion price applicable thereto shall be the
            lesser of (A) the lesser of the Set Price and the Mandatory
            Conversion Price on the Conversion Date and, (B) the lesser of the
            Set Price and the Mandatory Conversion Price on the date of the
            Holder's demand. Any such shares will be subject to the provision of
            this Section.

                  (iv) BUY-IN. In addition to any other rights available to the
            Holder, (i) if the Holder sells the shares it has converted and the
            Holder has provided the Company evidence of such sale reasonably
            satisfactory to the Company (the "Sale"), and (ii) if the Company
            fails to deliver to the Holder such certificate or certificates by
            the 5th Trading Day after the Conversion Date in accordance with
            Section 4(c)(ii), and if after such 5th Trading Day the Holder
            purchases (in an open market transaction or otherwise) Common Stock
            to deliver in satisfaction of a sale by such Holder of the
            Conversion Shares which the Holder anticipated receiving upon such
            conversion (a "Buy-In"), then the Company shall (A) pay in cash to
            the Holder (in addition to any remedies available to or elected by
            the Holder) the amount by which (x) the Holder's total purchase
            price (including brokerage commissions, if any) for the Common Stock
            so purchased exceeds (y) the product of (1) the aggregate number of
            shares of Common Stock that such Holder anticipated receiving from
            the conversion at issue multiplied by (2) the per share price of the
            Common Stock pursuant to the Sale, and (B) at the option of the
            Holder, (x) deliver the Conversion Shares not yet delivered under
            the Conversion Notice and subject to this provision, or (y)
            reinstate the principal and interest of this Debenture subject to
            such Conversion Notice. For example, if the Holder purchases Common
            Stock having a total purchase price of $11,000 to cover a Buy-In
            with respect to an attempted conversion of this Debenture with
            respect to which the market price of the Conversion Shares on the
            date of conversion was a total of $10,000, the Company shall be
            required to pay the Holder $1,000. The Holder shall provide the
            Company written notice indicating the amounts payable to the Holder
            in respect of the Buy-In and the basis for determining such amount.
            Notwithstanding anything contained herein to the contrary, if a
            Holder requires the Company to make payment in respect of a Buy-In
            for the failure to timely deliver certificates hereunder and the
            Company timely pays in full such payment, the Company shall not be
            required to pay such Holder liquidated damages under Section
            4(c)(iii) in respect of the certificates resulting in such Buy-In.

            (d) Conversion Restrictions.

                  (i) BENEFICIAL OWNERSHIP LIMITATION. Notwithstanding anything
            herein to the contrary, the Holder may not convert, and the Company
            may not cause the Holder to convert, this Debenture or receive
            shares of Common Stock as payment of interest hereunder to the
            extent such conversion or receipt of such interest payments would
            result in the Holder, together with any affiliate thereof,
            beneficially owning (as determined in accordance with Section 13(d)
            of the Exchange Act and the rules promulgated thereunder) in excess
            of 4.999% of the then issued and outstanding shares of Common Stock,
            including shares issuable upon conversion of, and payment of
            interest on, this Debenture or any other debenture of the Company
            held by such Holder after application of this Section. Since the
            Holder will not be obligated to report to the Company the number of
            shares of Common Stock it may hold at the time of a conversion
            hereunder, unless the conversion at issue would result in the
            issuance of shares of Common Stock in excess of 4.999% of the then
            outstanding shares of Common Stock without regard to any other
            shares which may be beneficially owned by the Holder or an affiliate
            thereof, the Holder shall have the authority and obligation to
            determine whether the restriction contained in this Section will
            limit any particular conversion hereunder and to the extent that the
            Holder determines that the limitation contained in this Section
            applies, the determination of which portion of the principal amount
            of this Debenture is convertible shall be the responsibility and
            obligation of the Holder. If the Holder has delivered a Conversion
            Notice for a principal amount of this Debenture that, without regard
            to any other shares that the Holder or its affiliates may
            beneficially own, would result in the issuance in excess of the
            permitted amount hereunder, the Company shall notify the Holder of
            this fact and shall honor the conversion for the maximum principal
            amount permitted to be converted on such Conversion Date in
            accordance with this Section. If this Debenture was not surrendered
            on the Conversion Date, the Company shall provide the Holder written
            notice of the amount actually converted. If the Holder surrendered
            this Debenture on the Conversion Date, the Company shall, at the
            option of the Holder, either retain any principal amount tendered
            for conversion in excess of the permitted amount hereunder for
            future conversions or return such excess principal amount to the
            Holder. The provisions of this Section may be waived by a Holder
            (but only as to itself and not to any other Holder) upon not less
            than 61 days prior notice to the Company. Other Holders shall be
            unaffected by any such waiver.

                  (ii) LIMITATION ON NUMBER OF SHARES ISSUABLE. Notwithstanding
            anything herein to the contrary, the Company shall not be required
            to issue to the Holder and any other holders of the Debentures, in
            the aggregate, in excess of the greater of (A) as of the date of the
            First Closing Date, 18.5% of the issued and outstanding shares of
            Common Stock at a price below the market price of the Common Stock
            on such date, and (B) the number of shares of Common Stock permitted
            to be issued pursuant to Nasdaq Rule 4350(i), as confirmed in
            writing by counsel to the Company, upon conversion of the Debentures
            (the "Maximum Aggregate Share Amount"), unless the Company first
            obtains shareholder approval permitting such issuances in accordance
            with Nasdaq rules. If the number of shares of Common Stock which
            would, notwithstanding the limitation set forth herein, be issuable
            and sold to the Holder equals or exceeds the Maximum Aggregate Share
            Amount, then, at any time thereafter, from time to time, at the sole
            election of the Holder, in whole or in part, the Company shall
            either: (i) honor the conversion of this Debenture by the Holder at
            the lowest possible conversion price which would permit such
            conversion without violating Nasdaq Rule 4350(i), provided, however,
            that such conversion price shall not be lower than the Set Price,
            and/or (ii) redeem the portion of this Debenture submitted to the
            Company, the conversion of which would exceed the Maximum Aggregate
            Share Amount, otherwise in accordance with Section 5(a).

                  (iii) LIMITATION ON NUMBER OF SHARES ISSUABLE DURING ANY 60
            DAY PERIOD. Notwithstanding anything herein to the contrary, during
            any rolling 60 consecutive calendar day period, the Company shall
            not be required to issue to the Holder a number of Conversion Shares
            during such period in the aggregate that exceeds 9.9% of the number
            of shares of Common Stock issued and outstanding on the date in
            question.

            (e) Anti-Dilution Provisions.

                  (i) DIVIDENDS, STOCK SPLITS, ETC. If the Company, at any time
            while this Debenture is outstanding, (A) shall pay a stock dividend
            or otherwise make a distribution or distributions on shares of its
            Common Stock or any other equity or equity equivalent securities
            payable in shares of Common Stock, (B) subdivide outstanding shares
            of Common Stock into a larger number of shares, (C) combine
            (including by way of reverse stock split) outstanding shares of
            Common Stock into a smaller number of shares, or (D) issue by
            reclassification of shares of the Common Stock any shares of capital
            stock of the Company, then the Set Price shall be multiplied by a
            fraction of which the numerator shall be the number of shares of
            Common Stock (excluding treasury shares, if any) outstanding before
            such event and of which the denominator shall be the number of
            shares of Common Stock outstanding after such event. Any adjustment
            made pursuant to this Section shall become effective immediately
            after the record date for the determination of stockholders entitled
            to receive such dividend or distribution and shall become effective
            immediately after the effective date in the case of a subdivision,
            combination or re-classification.

                  (ii) RIGHTS, OPTIONS, WARRANTS, ETC. If the Company, at any
            time while this Debenture is outstanding, shall issue rights,
            options or warrants to all holders of Common Stock (and not to
            holders of the Debentures) entitling them to subscribe for or
            purchase shares of Common Stock at a price per share less than the
            Set Price (the "Lower Price"), then the Set Price shall be
            multiplied by a fraction, of which the denominator shall be the
            number of shares of the Common Stock (excluding treasury shares, if
            any) outstanding on the date of issuance of such rights or warrants
            plus the number of additional shares of Common Stock offered for
            subscription or purchase, and of which the numerator shall be the
            number of shares of the Common Stock (excluding treasury shares, if
            any) outstanding on the date of issuance of such rights or warrants
            plus the number of shares which the aggregate offering price of the
            total number of shares so offered would purchase at the Set Price.
            Such adjustment shall be made whenever such rights, options or
            warrants are issued, and shall become effective immediately after
            the record date for the determination of stockholders entitled to
            receive such rights, options or warrants. However, upon the
            expiration of any such right, option or warrant to purchase shares
            of the Common Stock the issuance of which resulted in an adjustment
            in the Set Price pursuant to this Section, if any such right, option
            or warrant shall expire and shall not have been exercised, the Set
            Price shall immediately upon such expiration be recomputed and
            effective immediately upon such expiration be increased to the price
            which it would have been (but reflecting any other adjustments in
            the Set Price made pursuant to the provisions of this Section after
            the issuance of such rights or warrants) had the adjustment of the
            Set Price made upon the issuance of such rights, options or warrants
            been made on the basis of offering for subscription or purchase only
            that number of shares of the Common Stock actually purchased upon
            the exercise of such rights, options or warrants actually exercised.

                  (iii) FUTURE ISSUANCES. If the Company or any subsidiary
            thereof, at any time while this Debenture is outstanding, shall
            issue Capital Shares, or Capital Share Equivalents entitling any
            Person to acquire shares of Common Stock, at a price per share less
            than the Set Price (if the holder of the Capital Shares or Capital
            Share Equivalent so issued shall at any time, whether by operation
            of purchase price adjustments, reset provisions, floating
            conversion, exercise or exchange prices or otherwise, or due to
            warrants, options or rights issued in connection with such issuance,
            be entitled to receive shares of Common Stock at a price less than
            the Set Price, such issuance shall be deemed to have occurred for
            less than the Set Price) then, the Set Price shall be multiplied by
            a fraction, of which the denominator shall be the number of shares
            of the Common Stock (excluding treasury shares, if any) outstanding
            on the date of issuance of such securities plus the number of
            Capital Shares or Capital Share Equivalents offered for subscription
            or purchase, and of which the numerator shall be the number of
            shares of the Common Stock (excluding treasury shares, if any)
            outstanding on the date of issuance of such securities plus the
            number of shares which the aggregate offering price of the total
            number of shares so offered would purchase at the Set Price,
            provided, that for purposes hereof, all shares of Common Stock that
            are issuable upon conversion, exercise or exchange of Capital Share
            Equivalents shall be deemed outstanding immediately after the
            issuance of such Capital Share Equivalents. Such adjustment shall be
            made whenever such shares of Capital Shares or Capital Share
            Equivalents are issued. However, upon the expiration of any Capital
            Share Equivalents, the issuance of which resulted in an adjustment
            in the Conversion Price pursuant to this Section, if any such
            Capital Share Equivalents shall expire and shall not have been
            exercised, the Set Price shall immediately upon such expiration be
            recomputed and effective immediately upon such expiration be
            increased to the price which it would have been (but reflecting any
            other adjustments in the Set Price made pursuant to the provisions
            of this Section after the issuance of such Capital Share
            Equivalents) had the adjustment of the Set Price made upon the
            issuance of such Capital Share Equivalents been made on the basis of
            offering for subscription or purchase only that number of shares of
            Common Stock actually purchased upon the exercise of such Capital
            Share Equivalents actually exercised.

                  (iv) NO ADJUSTMENT. No adjustment to the Set Price pursuant to
            Section 4(e)(iii) will be made (A) upon the conversion of this
            Debenture or any other Debenture of this series or of any other
            series issued by the Company, or upon the issuance, conversion, or
            redemption of, or payment of interest under, any Convertible
            Securities issued pursuant to the Purchase Agreement; (B) upon the
            exercise or conversion of any Convertible Securities, options or
            warrants issued and outstanding on the Original Issue Date of this
            Debenture; (C) upon the issuance of Common Stock or issuance grant,
            exercise or conversion of any Convertible Securities which may
            hereafter be issued, granted, exercised or converted (x) as
            compensation to employees, consultants, brokers, investment bankers
            or members of the Board of Directors of the Company, or (y) under
            any employee benefit plan of the Company now existing or to be
            implemented in the future, so long as the issuance of such Common
            Stock or Convertible Securities is approved by a majority of the
            non-employee members of the Board of Directors of the Company or a
            majority of the members of a committee of non-employee directors
            established for such purpose; (D) upon the issuance of Common Stock
            or Convertible Securities in any transaction of the nature
            contemplated by Rule 145, promulgated under the Securities Act; (E)
            in connection with any strategic partnership or joint venture or
            acquisition (the primary purpose of which is not to raise equity
            capital for the Company) or (F) the issuance of Common Stock or the
            issuance, grant, exercise or conversion of Convertible Securities
            issued to a bank or equipment lessor (pursuant to transactions the
            primary purpose of which is not to raise equity capital for the
            Company).

                  (v) RIGHTS OF SHAREHOLDERS, ETC. If the Company, at any time
            while this Debenture is outstanding, shall distribute to all holders
            of Common Stock (and not to Holders) evidences of its indebtedness
            or assets or rights or warrants to subscribe for or purchase any
            security, then in each such case the Set Price at which this
            Debenture shall thereafter be convertible shall be determined by
            multiplying the Set Price in effect immediately prior to the record
            date fixed for determination of stockholders entitled to receive
            such distribution by a fraction of which the denominator shall be
            the VWAP determined as of the record date mentioned above, and of
            which the numerator shall be such VWAP on such record date less the
            then fair market value at such record date of the portion of such
            assets or evidence of indebtedness so distributed applicable to one
            outstanding share of the Common Stock as determined by the Board of
            Directors in good faith. In either case the adjustments shall be
            described in a statement provided to the Holder of the portion of
            assets or evidences of indebtedness so distributed or such
            subscription rights applicable to one share of Common Stock. Such
            adjustment shall be made whenever any such distribution is made and
            shall become effective immediately after the record date mentioned
            above.

            (f)   Miscellaneous.

                  (i) All calculations under this Section 4 shall be made to the
            nearest cent or the nearest 1/100th of a share, as the case may be.
            No adjustments in the Set Price shall be required if such adjustment
            is less than $0.01, provided, however, that any adjustments which by
            reason of this Section are not required to be made shall be carried
            forward and taken into account in any subsequent adjustment.

                  (ii) Whenever the Set Price is adjusted hereunder, the Company
            shall promptly mail to each Holder a notice setting forth the Set
            Price after such adjustment and setting forth a brief statement of
            the facts requiring such adjustment.

                  (iii) The Company covenants that it will at all times reserve
            and keep available out of its authorized and unissued shares of
            Common Stock solely for the purpose of issuance upon conversion of
            this Debenture and payment of interest on this Debenture, each as
            herein provided, free from preemptive rights or any other actual
            contingent purchase rights of persons other than the Holder, not
            less than such number of shares of the Common Stock as shall
            (subject to any additional requirements of the Company as to
            reservation of such shares set forth in the Purchase Agreement) be
            issuable (taking into account the adjustments and restrictions of
            Section 4) upon the conversion of the outstanding principal amount
            of this Debenture and payment of interest hereunder. The Company
            covenants that all shares of Common Stock that shall be so issuable
            shall, upon issue, be duly and validly authorized, issued, fully
            paid and nonassessable.

                  (iv) Upon a conversion hereunder, the Company shall not be
            required to issue stock certificates representing fractions of
            shares of the Common Stock, but may if otherwise permitted, make a
            cash payment in respect of any final fraction of a share based on
            the VWAP at such time. If the Company elects not, or is unable, to
            make such a cash payment, the Holder shall be entitled to receive,
            in lieu of the final fraction of a share, one whole share of Common
            Stock.

                  (v) The issuance of certificates for shares of the Common
            Stock on conversion of this Debenture shall be made without charge
            to the Holder for any documentary stamp or similar taxes that may be
            payable in respect of the issue or delivery of such certificate,
            provided that the Company shall not be required to pay any tax that
            may be payable in respect of any transfer involved in the issuance
            and delivery of any such certificate upon conversion in a name other
            than that of the Holder and the Company 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 the
            Company the amount of such tax or shall have established to the
            satisfaction of the Company that such tax has been paid.

      Section 5. Redemption.

            (a)  Optional Redemption by the Company. If the VWAP of the Common
      Stock exceeds 150% of the Set Price for a period of 20 consecutive Trading
      Days or if the Company consummates a public offering of its Common Stock
      at an offering price in excess of 150% of the Set Price, then, at such
      time, the Company shall have the right, upon 10 Trading Days' notice to
      the Holder (an "Optional Redemption Notice" and the date such notice is
      received by the Holder, the "Notice Date"), to redeem the entire principal
      amount of this Debenture or any portion thereof not less than $500,000
      then held by the Holder, at a cash price equal to the principal amount
      outstanding of this Debenture plus any accrued but unpaid interest hereon
      (the "Optional Redemption Price"); provided, however, the Company may only
      deliver an Optional Redemption Notice to the Holder if, on the Notice
      Date, (i) there is an effective Registration Statement pursuant to which
      the prospectus thereunder is available for use in the resale of all of the
      Conversion Shares issued to the Holder and all of the Conversion Shares as
      are issuable to the Holder upon conversion in full of this Debenture (and
      the Company believes, in good faith, that such effectiveness will continue
      uninterrupted for the foreseeable future), and (ii) the Common Stock is
      listed for trading on a Principal Market (and the Company believes, in
      good faith, that trading of the Common Stock on the Principal Market will
      continue uninterrupted for the foreseeable future). If any of the
      foregoing conditions shall cease to be in effect during the period between
      the Notice Date and the date the Optional Redemption Price is paid in
      full, then the Holders subject to such redemption may elect, by written
      notice to the Company given at any time after any of the foregoing
      conditions shall cease to be in effect, to invalidate ab initio such
      redemption, notwithstanding anything herein contained to the contrary. The
      Holders may convert any portion of the outstanding principal amount of the
      Debentures subject to an Optional Redemption Notice at the Set Price prior
      to the date that the Optional Redemption Price is due and paid in full.

            (b)  Mandatory Redemption. On each Mandatory Redemption Date, the
      Company shall redeem a portion of this Debenture equal to the Holder's
      Pro-Rata share of the Mandatory Redemption Amount (except that, if the
      Holder elects to exercise any other Debenture(s) on such Mandatory
      Redemption Date, the amount so redeemed pursuant to such other Debentures
      shall reduce the principal amount that may be redeemed hereunder on such
      Mandatory Redemption Date by such amount) at a cash price equal to 100% of
      the principal amount of this Debenture being redeemed. In lieu of a cash
      redemption payment, the Company may elect to pay, in whole or in part (and
      if in part, in multiples of $100,000), such amount to be redeemed on the
      applicable Mandatory Redemption Date in Conversion Shares based on a
      conversion price equal to the lesser of (i) 90% OF THE ADJUSTED VWAP
      DURING THE 22 TRADING DAYS IMMEDIATELY PRIOR TO THE APPLICABLE MANDATORY
      REDEMPTION DATE, and (ii) the Set Price (the "Mandatory Conversion
      Price"); provided, however, that the Mandatory Redemption shall only occur
      if, on the Mandatory Redemption Date and during the 30 calendar days prior
      thereto, (i) there is an effective Registration Statement pursuant to
      which the Holder is permitted to utilize the prospectus thereunder to
      resell all of the Conversion Shares issued to the Holder and all of the
      Conversion Shares as are issuable to the Holder upon conversion in full of
      the Debentures subject to such Mandatory Redemption are registered for
      resale by the Holder thereunder (and the Company believes, in good faith,
      that such effectiveness will continue uninterrupted for the foreseeable
      future), and (ii) the Common Stock is listed for trading on a Principal
      Market (and the Company believes, in good faith, that trading of the
      Common Stock on the Principal Market will continue uninterrupted for the
      foreseeable future); provided, further, that, on or prior to the first
      Trading Day of the 30 calendar day period prior to such Mandatory
      Redemption Date, the Company irrevocably notifies the Holder that it will
      issue Conversion Shares in lieu of cash and the Company includes in such
      notification the amount to be converted (the "Conversion Amount").
      Notwithstanding anything herein to the contrary, the Holder may elect,
      upon written notice to the Company not less than 2 Trading Days prior to a
      Mandatory Redemption Date, to waive any of the aforementioned conditions
      to the applicable Mandatory Redemption. In the event the Company elects to
      redeem this Debenture by the issuance of Conversion Shares, the Holder
      shall have the right, in its sole discretion, by notice to the Company
      prior to the applicable Mandatory Redemption Date, to increase the
      Conversion Amount by up to 100% or to decrease the Conversion Amount by up
      to 50% (except that, in the event one or more of the conditions to a
      Mandatory Redemption is not met and such condition(s) is waived by the
      Holder, the Holder may elect to decrease the applicable Conversion Amount
      by up to 100%). In the event the Conversion Amount is reduced by the
      Holder, such principal amount not converted but subject to the Mandatory
      Redemption, if not for the preceding sentence, shall be deferred to the
      end of this redemption schedule and cumulated with any other amounts so
      deferred. The Mandatory Conversion Price for any deferred Conversion
      Amount, shall be calculated at the date when actually converted, not at
      the time of deferral. By way of example, assume that this is the only
      Debenture issued under the Purchase Agreement, the Original Issue Date is
      December 5, 2001, the Effective Date is March 5, 2002 and there remains
      $5,000,000 in principal outstanding on this Debenture. Assume further that
      on March 5, 2002 the Company provided the Holder notice that it will
      redeem $400,000 of the principal amount of this Debenture by the issuance
      of Conversion Shares rather than cash (i.e. that the Conversion Amount
      shall be $400,000). On April 5, 2002, the Registration Statement is
      maintained effective and the Common Stock trades uninterrupted on the
      Principal Market during the 30 days prior to April 5. Finally, assume that
      on April 4, 2002, the Holder notifies the Company that it elects to reduce
      the Conversion Amount to $250,000. Under these circumstances, on April 5,
      2002, the Company shall redeem $350,000 principal amount of this
      Debenture, $250,000 of which shall be paid by the issuance of Conversion
      Shares based on the Mandatory Conversion Price on the Mandatory Redemption
      Date and the balance of $100,000, shall be paid in cash. The Mandatory
      Redemption of $150,000 of the principal amount of this Debenture shall be
      deferred until after the remaining principal amount outstanding of this
      Debenture has been subject to this Mandatory Redemption provision.
      Notwithstanding anything herein to the contrary, conversions hereunder
      shall be made as if pursuant to Section 4, including but not limited to,
      liquidated damages and fees for late delivery of Conversion Shares, and
      the Conversion Date for such purposes shall be the Mandatory Redemption
      Date. The Holder may convert any portion of the outstanding principal
      amount of the Debentures subject to a Mandatory Redemption prior to the
      date that the Mandatory Redemption is due and paid in full at the Set
      Price. Nothing herein shall preclude the Holder from converting this
      Debenture to the extent this Debenture remains unpaid and unconverted
      after the Mandatory Redemption Date.

            (c)  Redemption Procedure. The Optional Redemption Price is due on
      the 10th Trading Day following the Notice Date and payment of cash and/or
      issuance of Conversion Shares pursuant to the Mandatory Redemption shall
      be made on the Mandatory Redemption Date. If any portion of the Optional
      Redemption Price or cash payment for the Mandatory Redemption shall not be
      paid by the Company by expiration of such 10th Trading Day or Mandatory
      Redemption Date, as the case may be, interest shall accrue thereon at the
      rate of 18% per annum (or the maximum rate permitted by applicable law,
      whichever is less) until the Optional Redemption Price or cash payment of
      the Mandatory Redemption plus all such interest is paid in full. In
      addition, if any portion of the Optional Redemption Price or payment for
      the Mandatory Redemption remains unpaid after such date, the Holders
      subject to such redemption may elect, by written notice to the Company
      given at any time thereafter, to invalidate ab initio such redemption,
      notwithstanding anything herein contained to the contrary. If a Holder
      elects to invalidate such redemption the Company shall promptly, and, in
      any event, not later than 3 Trading Days from receipt of such Holder's
      notice of such election, return to such Holder all of the Debentures for
      which the Optional Redemption Price shall not have been paid in full. With
      respect to the principal amount of any Debentures to be converted pursuant
      to a Mandatory Redemption and subject to such invalidation, the conversion
      price as to any conversions pursuant to Section 4(a)(i) thereafter shall
      equal the Mandatory Conversion Price on the date such demand is made
      (notwithstanding the fact that such a date may not be a Mandatory
      Conversion Date).

      Section 6. Dividends, Mergers, Consolidations, Reclassifications, Etc.

            (a)  Notice of Certain Events. If (i) the Company shall declare a
      dividend (or any other distribution) on the Common Stock; (ii) the Company
      shall declare a special nonrecurring cash dividend on or a redemption of
      the Common Stock; (iii) the Company shall authorize the granting to all
      holders of the Common Stock rights or warrants to subscribe for or
      purchase any shares of capital stock of any class or of any rights; (iv)
      the approval of any stockholders of the Company shall be required in
      connection with any reclassification of the Common Stock, any
      consolidation or merger to which the Company is a party, any sale or
      transfer of all or substantially all of the assets of the Company, or any
      compulsory share exchange whereby the Common Stock is converted into other
      securities, cash or property; or (v) the Company shall authorize the
      voluntary or involuntary dissolution, liquidation or winding up of the
      affairs of the Company; then, in each case, the Company shall cause to be
      filed at each office or agency maintained for the purpose of conversion of
      the Debentures, and shall cause to be mailed to the Holder at its last
      addresses as they shall appear upon the stock books of the Company, at
      least 20 calendar days prior to the applicable record or effective date
      hereinafter specified, a notice stating (i) the date on which a record is
      to be taken for the purpose of such dividend, distribution, redemption,
      rights or warrants, or if a record is not to be taken, the date as of
      which the holders of the Common Stock of record to be entitled to such
      dividend, distributions, redemption, rights or warrants are to be
      determined, or (ii) the date on which such reclassification,
      consolidation, merger, sale, transfer or share exchange is expected to
      become effective or close, and the date as of which it is expected that
      holders of the Common Stock of record shall be entitled to exchange their
      shares of the Common Stock for securities, cash or other property
      deliverable upon such reclassification, consolidation, merger, sale,
      transfer or share exchange, provided, that the failure to mail such notice
      or any defect therein or in the mailing thereof shall not affect the
      validity of the corporate action required to be specified in such notice.
      The Holder is entitled to convert this Debenture during the 20-day period
      commencing the date of such notice to the effective date of the event
      triggering such notice.

            (b)  Change of Control. In case of any Change of Control or sale or
      disposition by the Company of all or in excess of 50% of its assets in one
      or more transactions (whether or not such sale would constitute a Change
      of Control Transaction) or redemption or repurchase of more than a de
      minimis number of shares of Common Stock or other equity securities of the
      Company, the Holder shall have the right to either (i) avail itself of any
      of the rights, remedies and procedures otherwise available to the Holder
      pursuant to Section 3(b) as if an Event of Default had occurred, (ii)
      convert its aggregate principal amount of Debentures then outstanding into
      the shares of stock and other securities, cash and property receivable
      upon or deemed to be held by holders of Common Stock following such
      merger, consolidation or sale, and such Holder shall be entitled upon such
      event or series of related events to receive such amount of securities,
      cash and property as the shares of Common Stock into which such aggregate
      principal amount of Debentures could have been converted immediately prior
      to such merger, consolidation or sale would have been entitled, or (iii)
      in the case of Change of Control involving a merger in which the Company
      is not the surviving corporation or a consolidation, (A) require the
      surviving entity to issue convertible subordinated debentures in such face
      amount equal to the aggregate principal amount of Debentures then held by
      the Holder, plus all accrued and unpaid interest and other amounts owing
      thereon, which newly issued debentures shall have terms identical
      (including with respect to conversion) to the terms of this Debenture and
      shall be entitled to all of the rights and privileges of a Holder of this
      Debenture and the agreements pursuant to which this Debenture was issued
      (including, without limitation, as such rights relate to the acquisition,
      transferability, registration and listing of such shares of stock or other
      securities issuable upon conversion thereof), and (B) simultaneously with
      the issuance of such convertible subordinated debentures, shall have the
      right to convert such instrument only into shares of stock and other
      securities, cash and property receivable upon or deemed to be held by
      holders of Common Stock following such merger or consolidation. In the
      case of clause (iii), the conversion price applicable for the newly issued
      convertible subordinated debentures shall be based upon the amount of
      securities, cash and property that each share of Common Stock would
      receive in such transaction and the Set Price in effect immediately prior
      to the effectiveness or closing date for such transaction. The terms of
      any such merger, sale or consolidation shall include such terms so as to
      continue to give the Holders the right to receive the securities, cash and
      property set forth in this Section upon any conversion or redemption
      following such event. This provision shall similarly apply to such
      successive events. The terms of any agreement to be executed in connection
      with any Change of Control transaction shall include terms requiring any
      successor or surviving entity to comply with the provisions of this
      Section.

            (c)  Reclassification. In case of any reclassification of the Common
      Stock (other than a change in par value or a change from par value to no
      par value) or any compulsory share exchange pursuant to which the Common
      Stock is converted into other securities, cash or property, the Holder
      shall have the right thereafter to, at its option, (i) to convert, at any
      time, in whole or in part, the then outstanding principal amount, together
      with all accrued but unpaid interest and any other amounts then owing
      hereunder in respect of this Debenture only into the shares of stock and
      other securities, cash and property receivable upon or deemed to be held
      by holders of the Common Stock following such reclassification or share
      exchange, and the Holder of this Debenture shall be entitled upon such
      event to receive such amount of securities, cash or property as the shares
      of the Common Stock of the Company into which the then outstanding
      principal amount, together with all accrued but unpaid interest and any
      other amounts then owing hereunder in respect of this Debenture could have
      been converted immediately prior to such reclassification or share
      exchange would have been entitled, or (ii) to cause the Company to
      exercise its right to redeem the aggregate outstanding principal amount of
      this Debenture, plus all interest and other amounts due and payable
      thereon, pursuant to Section 5. The entire redemption price due hereunder
      shall be paid in cash. This provision shall similarly apply to successive
      reclassifications or share exchanges.

      Section 7. Subordination

            (a) Agreement To Subordinate. The Company agrees, and the Holder, by
      accepting this Debenture agrees, that the indebtedness evidenced by this
      Debenture is subordinated in right of payment, to the extent and in the
      manner provided in this Section 7, to the prior payment and/or
      cancellation in full of all Senior Indebtedness of the Company and that
      such subordination is for the benefit of, and enforceable by, the holders
      of such Senior Indebtedness.

            (b)  Liquidation, Dissolution, Bankruptcy. Upon any payment or
      distribution of the assets of the Company to creditors upon a total or
      partial liquidation or a total or partial dissolution of the Company or in
      a bankruptcy, reorganization, insolvency, receivership or similar
      proceeding relating to the Company or its property:

            (i)   holders of Senior Indebtedness of the Company shall be
                  entitled to receive payment in full of such Senior
                  Indebtedness before the Holder shall be entitled to receive
                  any payment of principal of or interest on the Debentures; and

            (ii)  until the Senior Indebtedness of the Company is paid in full,
                  any payment or distribution to which the Holder would be
                  entitled but for this Section 7 shall be made by the
                  liquidating trustee or agent or other person making such
                  payment or distribution (whether a trustee in bankruptcy, a
                  receiver or liquidating trustee or otherwise) directly to
                  holders of such Senior Indebtedness as their interests may
                  appear to the extent necessary to pay in full all Senior
                  Indebtedness remaining unpaid after giving effect to any prior
                  or concurrent payment or distribution, or provision therefor,
                  to holders of such Senior Indebtedness.

            (iii) in the event that, notwithstanding the foregoing, any payment
                  or distribution of assets of the Company of any kind or
                  character, whether in cash, property or securities (other than
                  securities issued to the Holder upon conversion under or
                  redemption of this Debenture, cash paid for liquidated damages
                  pursuant to Section 7(c) or shares of common stock of the
                  Company as reorganized or readjusted, or securities of the
                  Company or any other corporation provided for by a plan of
                  reorganization or readjustment, the payment of which is
                  subordinated to the payment of all Senior Indebtedness which
                  may at the time be outstanding on terms not less favorable
                  than those of this Section 7) shall be received by the Holder
                  before all Senior Indebtedness is paid in full, such payment
                  or distribution shall be paid over to the Senior Creditor, for
                  application to the payment of all Senior Indebtedness
                  remaining unpaid until all such Senior Indebtedness shall have
                  been paid in full, or provision made for its payment, after
                  giving effect to any prior or concurrent payment or
                  distribution on the Senior Indebtedness.

            (c)  Event of Default and Notice. The Holder covenants and agrees
      that: (a) if an Event of Default shall occur under this Debenture, other
      than by conversion of this Debenture into Conversion Shares or the
      issuance of shares of Common Stock in lieu of liquidated damages, the
      Holder will not demand payment of any principal of or interest on this
      Debenture or demand, during any consecutive 120 day period, in excess of
      such Holder's Pro-Rata share of $200,000 in cash for the payment of
      liquidated damages pursuant to this Debenture, until one hundred and
      twenty (120) days after the Holder has provided the Senior Creditor the
      written notice of the Event of Default at the addresses of the Senior
      Creditor set forth in this Section 7; (b) the Holder agrees not to oppose,
      interfere with or otherwise attempt to prevent the Senior Creditor from
      enforcing its security interests in and/or liens on any of collateral held
      by the Senior Creditor or otherwise realizing upon any of such collateral;
      (c) the Holder shall not attempt to take possession of and/or to attempt
      to foreclose on any lien, security interest or other encumbrance on or in
      any of the collateral held by the Senior Creditor prior to the time all of
      the Senior Indebtedness held by the Senior Creditor shall have been fully,
      finally and indefeasibly paid in cash and all financing arrangements and
      commitments between the Company and Senior Creditor shall have been
      terminated; and (d) the Holder shall not, directly or indirectly, take any
      action to contest or challenge the validity, legality, enforceability,
      perfection, priority or avoidability of any of the Senior Indebtedness
      held by the Senior Creditor, any documents evidencing the Senior
      Indebtedness or any of the security interests and/or liens held by Senior
      Creditor in or on any of the collateral. Upon notification to the Company
      of an Event of Default, the Holder shall concurrently notify the Senior
      Creditor in writing of such Event of Default. In the event that the Holder
      is precluded under this Subsection 7(c) from demanding a cash payment for
      accrued liquidated damages, the Holder may elect to demand shares of
      Common Stock in lieu of cash based on a conversion rate equal to the
      Mandatory Conversion Price (notwithstanding the fact that such date may
      not be a Mandatory Conversion Date).

            (d)  Default on Senior Indebtedness. The Company may not pay the
      principal of, premium (if any) or interest on this Debenture in cash and
      may not repurchase, redeem or otherwise retire this Debenture (other than
      securities issued to the Holder upon conversion under or redemption of,
      this Debenture) if (i) any Senior Indebtedness of the Company is not paid
      when due or (ii) any other default on such Senior Indebtedness occurs and
      the maturity of such Senior Indebtedness is accelerated in accordance with
      its terms unless, in either case, (x) the default has been cured or waived
      and any such acceleration has been rescinded or (y) such Senior
      Indebtedness has been paid in full.

            (e)  When Distribution Must Be Paid Over. If a distribution
      prohibited by this Section 7 is made to Holders, the Holders who receive
      such distribution shall hold such distribution in trust for holders of
      Senior Indebtedness of the Company and pay such distribution over to them
      as their interests may appear.

            (f)  Waiver of Certain Rights. The Holder hereby waives any and all
      rights to (a) require Senior Creditor to marshall any property or assets
      of the Company or to resort to any of the property or assets of the
      Company in any particular order or manner, (b) require Senior Creditor to
      enforce any guaranty or any security interest or lien given by any person
      or entity other than the Company to secure the payment of any or all of
      the Senior Indebtedness held by the Senior Creditor as a condition
      precedent or concurrent to taking any action against or with respect to
      any collateral securing such Senior Indebtedness and/or (c) bring any
      action to contest the validity, legality, enforceability, perfection,
      priority or avoidability of any of the Senior Indebtedness held by the
      Senior Creditor, any of the documents evidencing the Senior Indebtedness
      held by the Senior Creditor or any of the security interests and/or liens
      of Senior Creditor in or on any of the collateral securing its Senior
      Indebtedness.

            (g)  Priority of Security Interests. Any and all security interests,
      liens, rights and interests of the Holder, whether now or hereafter
      arising and howsoever existing, in or on any or all of the collateral now
      or hereafter securing the Senior Indebtedness held by the Senior Creditor
      shall be and hereby are subordinated to any and all security interests,
      liens, rights and interests of Senior Creditor in and to any collateral
      now or hereafter securing such Senior Indebtedness, irrespective of (a)
      the time, order, manner or method of creation, attachment or perfection of
      the respective security interests and/or liens granted to the Holder or
      the Senior Creditor in or on any or all of the property or assets of the
      Company, (b) the time or manner of the filing of their respective
      financing statements, (c) whether the Holder or the Senior Creditor or any
      bailee or agent thereof holds possession of any or all of the property or
      assets of the Company, (d) the dating, execution or delivery of any
      agreement, document or instrument granting the Holder or the Senior
      Creditor security interests and/or liens in or on any or all of the
      property or assets of the Company, (e) the giving or failure to give
      notice of the acquisition or expected acquisition of any purchase money or
      other security interests and (f) any provision of the Uniform Commercial
      Code or any other applicable law to the contrary. For purposes of the
      foregoing allocation of priorities, any claim of a right of setoff shall
      be treated in all respects as a security interest and no claimed right of
      setoff shall be asserted to defeat or diminish the rights or priorities
      provided for herein.

            (h)  Bankruptcy. The provisions of this Section 7 shall continue in
      full force and effect after the filing of any petition for relief by or
      against the Company under the United States Bankruptcy Code (the "Code")
      and all converted or succeeding cases in respect thereof (all references
      herein to the Company being deemed to apply to the Company as a
      debtor-in-possession and to a trustee for the Company), and shall apply
      with full force and effect with respect to all collateral held by the
      Senior Creditor, and to all Senior Indebtedness incurred by the Company
      from the Senior Creditor, subsequent to such filing.

            (i)  Relative Rights. This Section 7 defines the relative rights of
      Holders and holders of Senior Indebtedness of the Company. Nothing in this
      Indenture shall:

                  (i) impair, as between the Company and Holders, the obligation
            of the Company, which is absolute and unconditional, to pay
            principal of and interest on and liquidated damages in respect of,
            the Debentures in accordance with their terms; or

                  (ii) prevent any Holder from exercising its available remedies
            upon an Event of Default, subject to the rights of holders of Senior
            Indebtedness of the Company to receive distributions otherwise
            payable to Holders.

            (j)  Payment in Stock. Notwithstanding any provision in this Section
      7, the Company may at any time pay or redeem this Debenture in shares of
      Common Stock pursuant to the terms and conditions set forth herein and the
      Holder may receive such shares of Common Stock free and clear of any
      claims of the holders of Senior Indebtedness. Nothing herein shall
      restrict delay or otherwise affect the Holder's right to receive
      securities upon any conversion or issuance under this Debenture.

            (k)  Reliance by Holders of Senior Indebtedness on Subordination
      Provisions. The Holder by accepting a Debenture acknowledges and agrees
      that the foregoing subordination provisions are, and are intended to be,
      an inducement and a consideration to each holder of any Senior
      Indebtedness of the Company, whether such Senior Indebtedness was created
      or acquired before or after the issuance of the Debentures, to acquire and
      continue to hold, or to continue to hold, such Senior Indebtedness and
      such holder of such Senior Indebtedness shall be deemed conclusively to
      have relied on such subordination provisions in acquiring and continuing
      to hold, or in continuing to hold, such Senior Indebtedness.

            (l)  Definitions.

      "Senior Indebtedness" of the Company means the principal of, premium (if

      is allowed in such proceedings) on, and fees and other amounts owing in
      respect of any indebtedness of the Company for money borrowed, including
      but not limited to indebtedness now or hereafter borrowed from or
      otherwise due to the Senior Creditor unless in the instrument creating or
      evidencing the same or pursuant to which the same is outstanding it is
      expressly provided that such obligations are not superior in right of
      payment to the Debentures whether outstanding on the date of this
      Debenture is issued or thereafter incurred; provided, however, that Senior
      Indebtedness shall not include:

      Indebtedness to Fleet National Bank is no longer outstanding, Senior
      Creditor shall mean the creditor or creditors of the Company which shall
      have substantially refinanced the Senior Indebtedness to Fleet National

subsidiaries not to, without the consent of the Holder, (i) amend its
certificate of incorporation, bylaws or other charter documents so as to
adversely affect any rights of the Holder; (ii) repay, repurchase or offer to
repay, repurchase or otherwise acquire shares of its Common Stock or other

Company shall not be subject to liquidated damages or other penalties arising
from the Company's failure to timely deliver certificates pursuant to this
Debenture, or for failure to deliver an opinion of counsel, if such failure
results from Force Majeure.

      Section 11. Rights as Holder. This Debenture shall not entitle the Holder
to any of the rights of a stockholder of the Company, including without
limitation, the right to vote, to receive dividends and other distributions, or
to receive any notice of, or to attend, meetings of stockholders or any other
proceedings of the Company, unless and to the extent converted into shares of
Common Stock in accordance with the terms hereof.

      Section 12. Replacement Debentures. If this Debenture shall be mutilated,
lost, stolen or destroyed, the Company shall execute and deliver, in exchange
and substitution for and upon cancellation of a mutilated Debenture, or in lieu
of or in substitution for a lost, stolen or destroyed debenture, a new Debenture
for the principal amount of this Debenture so mutilated, lost, stolen or
destroyed but only upon receipt of evidence of such loss, theft or destruction
of such Debenture, and of the ownership hereof, and indemnity, if requested, all
reasonably satisfactory to the Company.

      Section 13. Governing Law. This Debenture shall be governed by and
construed in accordance with the laws of the State of New York, without giving
effect to conflicts of laws thereof. The Company and the Holder hereby
irrevocably submit to the exclusive jurisdiction of the state and federal courts
sitting in the City of New York, Borough of Manhattan, for the adjudication of
any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and
agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of any such court, or that such suit,
action or proceeding is improper. Each of the Company and the Holder hereby
irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by receiving a copy thereof sent
to the Company at the address in effect for notices to it under this Debenture
and agrees that such service shall constitute good and sufficient service of
process and notice thereof. Nothing contained herein shall be deemed to limit in
any way any right to serve process in any manner permitted by law.

      Section 14. Waivers. Any waiver by the Company or the Holder of a breach
of any provision of this Debenture shall not operate as or be construed to be a
waiver of any other breach of such provision or of any breach of any other
provision of this Debenture. The failure of the Company or the Holder to insist
upon strict adherence to any term of this Debenture on one or more occasions
shall not be considered a waiver or deprive that party of the right thereafter
to insist upon strict adherence to that term or any other term of this
Debenture. Any waiver must be in writing.

      Section 15. Severability. If any provision of this Debenture is invalid,
illegal or unenforceable, the balance of this Debenture shall remain in effect,
and if any provision is inapplicable to any person or circumstance, it shall
nevertheless remain applicable to all other persons and circumstances. If it
shall be found that any interest or other amount deemed interest due hereunder
shall violate applicable laws governing usury, the applicable rate of interest
due hereunder shall automatically be lowered to equal the maximum permitted rate
of interest. The Company covenants (to the extent that it may lawfully do so)
that it shall not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law or
other law which would prohibit or forgive the Company from paying all or any
portion of the principal of or interest on the Debentures as contemplated
herein, wherever enacted, now or at any time hereafter in force, or which may
affect the covenants or the performance of this indenture, and the Company (to
the extent it may lawfully do so) hereby expressly waives all benefits or
advantage of any such law, and covenants that it will not, by resort to any such
law, hinder, delay or impede the execution of any power herein granted to the
Holder, but will suffer and permit the execution of every such as though no such
law has been enacted.

      Section 16. Non Trading Days. Whenever any payment or other obligation
hereunder shall be due on a day other than a Trading Day, such payment shall be
made on the next succeeding Trading Day.

      Section 17. Headings. The headings used in this Debenture are used for
convenience only and are not to be considered in construing or interpreting this
Debenture.

      Section 18. Assignment. Notwithstanding any provision herein, the Holder
shall not sell, assign, pledge, encumber, or otherwise transfer this Debenture
or any rights hereunder to any person or entity without the consent of the
Company, which consent shall not be unreasonably withheld; provided, however, in
no event shall the Holder assign this Debenture to any person, entity or company
that, in the reasonable judgment of the Company, are in direct competition with
the Company, including but not limited to, persons, entities or companies in the
telecommunications industry, data communications industry or the business of

                          REGISTRATION RIGHTS AGREEMENT

      THIS REGISTRATION RIGHTS AGREEMENT, dated as of January 15, 2002, between
the investor or investors signatory hereto (each an "Investor" and together the
"Investors"), and Fibercore, Inc., a Nevada corporation (the "Company").

      WHEREAS, simultaneously with the execution and delivery of this Agreement,
the Investors are purchasing from the Company, pursuant to the Convertible
Subordinated Debentures and Warrants Purchase Agreement, dated the date hereof
(the "Purchase Agreement") (CAPITALIZED TERMS NOT DEFINED HEREIN SHALL HAVE THE
MEANINGS ASCRIBED TO THEM IN THE PURCHASE AGREEMENT), $6,000,000, in the
aggregate, principal amount of the Company's Convertible Subordinated Debentures
and Warrants; and

      WHEREAS, the Company desires to grant to the Investors the registration
rights set forth herein with respect to the Conversion Shares of Common Stock
issuable upon conversion of, or as interest upon, the Convertible Subordinated
Debentures, shares of Common Stock issuable upon exercise of the Warrants
purchased pursuant to the Purchase Agreement and shares issuable in the event of
a registration default pursuant to Section 3(f) (the "Securities").

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

      Section 1. [INTENTIONALLY OMMITTED]

      Section 2. Restrictions on Transfer. Each Investor acknowledges and
understands that prior to the registration of the Securities as provided herein,
the Securities are "restricted securities" as defined in Rule 144 promulgated
under the Securities Act. Each Investor understands that no disposition or
transfer of the Securities may be made by Investor in the absence of (i) an
opinion of counsel to the Investor, in form and substance reasonably
satisfactory to the Company, that such transfer may be made without registration
under the Securities Act or (ii) such registration.

      With a view to making available to the Investors the benefits of Rule 144
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) comply with the provisions of paragraph (c)(1) of Rule 144;

            (b) file with the SEC in a timely manner all reports and other
      documents required to be filed with the SEC pursuant to Section 13 or
      15(d) under the Exchange Act by companies subject to either of such
      sections, irrespective of whether the Company is then subject to such
      reporting requirements; and

            (c) upon request by the Transfer Agent, the Company shall provide
      the Transfer Agent an opinion of counsel, which opinion shall be
      reasonably acceptable to the Transfer Agent, that the Investor has
      complied with the applicable conditions of Rule 144 (or any similar
      provision then in force) under the Securities Act.

      Section 3. Registration Rights With Respect to the Securities.

            (a) The Company agrees that it will prepare and file with the SEC,
      within 30 calendar days after the First Closing Date, a registration
      statement on Form S-3 (or such other appropriate registration statement
      form) under the Securities Act at the sole expense of the Company (except
      as provided in Section 3(c) hereof), in respect of the Investors, so as to
      permit the resale of the Securities purchased on the First and Second
      Closing Dates under the Act by the Investors as selling stockholders and
      not as underwriters. The Company agrees that it will prepare and file with
      the SEC, within 30 calendar days after any Subsequent Closing Date, a
      registration statement on Form S-3 (or such other appropriate registration
      statement form) under the Securities Act at the sole expense of the
      Company (except as provided in Section 3(c) hereof), in respect of the
      Investors, so as to permit the resale of the Securities purchased at such
      Subsequent Closing Date under the Act by the Investors as selling
      stockholders and not as underwriters.

            (b) The Company shall cause the Registration Statement registering
      the Securities purchased at the First and Second Closing to become
      effective within 60 calendar days (90 calendar days in the event of a
      review by the SEC) after the First Closing Date, or, if earlier, within 5
      days of SEC clearance to request acceleration of effectiveness. The
      Company shall cause the Registration Statement registering the Securities
      purchased the applicable Subsequent Closing to become effective within 60
      calendar days (90 calendar days in the event of a review by the SEC) after
      such Subsequent Closing date, or, if earlier, within 5 days of SEC
      clearance to request acceleration of effectiveness. The number of shares
      designated in the Registration Statement to be registered shall include
      all the applicable Warrant Shares, 100% of the already converted
      applicable Conversion Shares, if any, held by any Investor on the filing
      date and at least 200% of the greater of the number of shares which would
      be issuable upon the conversion of the principal amount of the applicable
      Convertible Subordinated Debentures issued and to be issued at the
      Mandatory Conversion Price in effect (i) on the Closing Date the
      applicable Registration Date is required to be filed, or (ii) on the date
      of the filing of such Registration Statement, and such number of shares as
      the Company deems prudent for the purpose of issuing shares of Common
      Stock as interest on the Convertible Subordinated Debentures, and shall
      include appropriate language regarding reliance upon Rule 416 to the
      extent permitted by the SEC. The Company will notify the Investors and the
      Company's transfer agent of the effectiveness of a Registration Statement
      within 1 Trading Day of such event. After an Effective Date, within 30
      days after the day on which the Holder gives notice to the Company that
      the number of Securities registered for resale by the Holder relating to
      such Effective Date, notwithstanding the limitation on conversion herein
      and in the Purchase Agreement, is less than 100% of the number of the
      Securities (calculated at the Mandatory Conversion Price on such date)
      held by the Holder on such date (the "Further Registration Date"), the
      Company shall file a further registration statement registering a number
      of shares of Common Stock to the extent that at least 200% of the shares
      which would be required to be issued upon the conversion of the remaining
      applicable Convertible Subordinated Debentures at the Mandatory Conversion
      Price on the date of the filing of such further registration statement are
      registered and shall prosecute such additional registration statement to
      effectiveness within 60 calendar days of the Further Registration Date (90
      calendar days in the event of a review by the SEC). As to any Registration
      Statement, each Investor shall have the right to convert all or any of its
      applicable Convertible Subordinated Debenture into up to a number of
      registered shares of Common Stock equal to such Investor's fraction of the
      aggregate Purchase Price for such Convertible Subordinated Debenture
      multiplied by the initially registered and, if applicable, subsequently
      registered Securities; provided, however, in no event shall this provision
      limit each Investor's right to convert its Convertible Subordinated
      Debenture into unregistered shares of Common Stock.

            (c) The Company will maintain each Registration Statement or
      post-effective amendment filed under this Section 3 effective under the
      Securities Act until the earlier of (i) the date that none of the
      Securities covered by such Registration Statement are or may become issued
      and outstanding, (ii) the date that all of the Securities registered
      thereunder have been sold pursuant to such Registration Statement, (iii)
      the date the Investors receive an opinion of counsel to the Company, which
      counsel shall be reasonably acceptable to the Investors, that the
      Securities registered thereunder may be sold under the provisions of Rule
      144 without limitation as to volume, (iv) all Securities registered
      thereunder have been otherwise transferred to persons who may trade such
      shares without restriction under the Securities Act, and the Company has
      delivered a new certificate or other evidence of ownership for such
      securities not bearing a restrictive legend, or (v) three (3) years from
      the applicable Effective Date.

            (d) All fees, disbursements and out-of-pocket expenses and costs
      incurred by the Company in connection with the preparation and filing of
      the Registration Statements hereunder and in complying with applicable
      securities and Blue Sky laws (including, without limitation, all
      attorneys' fees of the Company) shall be borne by the Company. The
      Investors shall bear the cost of underwriting and/or brokerage discounts,
      fees and commissions, if any, applicable to the Securities being
      registered and the fees and expenses of their counsel. Five Trading Days
      prior to the Trading Day on which the Company intends to file a
      Registration Statement or any amendment thereto (excluding amendments
      deemed to result from the filing of documents incorporated by reference
      therein), the Company shall deliver to the Investors and one firm of
      counsel representing the Investors, copies of such Registration Statement
      as proposed to be filed, which documents will be subject to review and
      comment by the Investors and such counsel, provided, however, that if the
      Investor or counsel to the Investor shall not within five Trading Days
      following receipt of such Registration Statement deliver written comments
      regarding such Registration Statement to the Company, the applicable time
      periods set forth in Sections 3(a) and Section 3(b) shall be extended by
      one Trading Day for each Trading Day on which the Investor or counsel to
      the Investor fails to deliver such written comments to the company
      following such initial five (5) Trading Day period. The Company shall
      provide each Investor with copies of any comment letters received from the
      SEC with respect thereto within 2 Trading Days of receipt thereof. The
      Company shall qualify any of the securities for sale in such states as any
      Investor reasonably designates and shall furnish indemnification in the
      manner provided in Section 6 hereof. However, the Company shall not be
      required to qualify in any state which will require an escrow or other
      restriction relating to the Company and/or the sellers, or which will
      require the Company to qualify to do business in such state or require the
      Company to file therein any general consent to service of process. The
      Company at its expense will supply the Investors with copies of the
      applicable Registration Statement and the prospectus included therein and
      other related documents in such quantities as may be reasonably requested
      by the Investors.

            (e) The Company shall not be required by this Section 3 to include
      an Investor's Registrable Securities in any Registration Statement which
      is to be filed if, in the opinion of counsel for both the Investor and the
      Company (or, should they not agree, in the opinion of another counsel
      experienced in securities law matters acceptable to counsel for the
      Investor and the Company) the proposed offering or other transfer as to
      which such registration is requested is exempt from applicable federal and
      state securities laws and would result in all purchasers or transferees
      obtaining securities which are not "restricted securities", as defined in
      Rule 144 under the Securities Act.

            (f) In the event that (i) a Registration Statement is not filed by
      the Company in a timely manner as set forth in Section 3(a), (ii) a
      Registration Statement is not declared effective by the SEC within the
      period of time set forth in Section 3(b) herein, or within 5 days of
      clearance by the SEC to request effectiveness, (iii) such Registration
      Statements are not maintained as effective by the Company for the period
      set forth in Section 3(c) above, or (iv) the additional registration
      statement referred to in Section 3(b) is not filed within 30 calendar days
      or declared effective within 60 calendar days (or, if applicable 90
      calendar days) as set forth therein (each a "Registration Default") then
      the Company will pay each Investor (pro-rata on a monthly basis), for each
      Registration Default then in effect, as liquidated damages and not as a
      penalty, during any period in which a Registration Default is occurring,
      2% per month (pro-rated to the number of days of the month elapsed) of (i)
      the then outstanding principal amount of the Convertible Subordinated
      Debentures, (ii) the value of any Conversion Shares and Warrant Shares
      already converted or exercised (valued at the average of all of the VWAPs
      during the applicable month multiplied by the number of such shares), and
      (iii) the value of any outstanding Warrants (valued at the difference
      between the average VWAP during the applicable month and the Exercise
      Price multiplied by the number of Warrant Shares the Warrants are
      exercisable into), held by such Investor until such corresponding
      Registration Default no longer exists ("Liquidated Damages"). Such payment
      of the Liquidated Damages shall be made to the Investors in cash, or, at
      the option of the Company, in registered shares of Common Stock (based on
      the Mandatory Conversion Price) on the Trading Day prior to the date of
      payment) on the last day of each month during which a Registration Default
      occurred or was continuing, without demand therefor by the Investor;
      provided, however, that the payment of the Liquidated Damages shall not
      relieve the Company from its obligations to register the Securities
      pursuant to this Section.

            If the Company does not remit the payment to the Investors as set
      forth above, the Company will pay the Investors reasonable costs of
      collection, including attorneys' fees, in addition to the Liquidated
      Damages and interest of 18% per annum on any liquidated damage payments
      not made in a timely manner as set forth above. The registration of the
      Securities pursuant to this provision shall not affect or limit the
      Investors' other rights or remedies as set forth in this Agreement.

            (g) Except as set forth on Schedule A hereto, the Company shall be
      precluded from including in any registration statement which is required
      to be filed pursuant to this Section 3 any other securities apart from the
      Registrable Securities, without the prior written consent of a majority in
      interest of the Investors. Until after the Effective Date of the
      Registration Statement registering the Securities relating to the First
      and Second Closing, the Company shall be precluded from filing any other
      registration statements other than on Form S-8 or Form S-4. During the
      periods beginning on any Subsequent Closing Date until the Effective Date
      relating to such Subsequent Closing Date, the Company shall be precluded
      from filing any other registration statements other than on Form S-8 or
      Form S-4.

            (h) If at any time or from time to time after the Effective Date of
      any Registration Statement, the Company notifies the Investors in writing
      of the existence of a Potential Material Event (as defined in Section 3(i)
      below), the Investors shall not offer or sell any Securities or engage in
      any other transaction involving or relating to Securities, from the time
      of the giving of notice with respect to a Potential Material Event until
      the Investors receive written notice from the Company that such Potential
      Material Event either has been disclosed to the public or no longer
      constitutes a Potential Material Event; provided, however, that the
      Company may not so suspend the right to such holders of Securities for
      more than twenty-two (22) Trading Days in the aggregate during any twelve
      month period, during the period a Registration Statement is required to be
      in effect, and if such period is exceeded, such event shall be a
      Registration Default and subject to Liquidated Damages as set forth in
      Section 3(f) hereof. THE COMPANY MUST GIVE THE INVESTORS NOTICE IN WRITING
      PRIOR TO THE FIRST DAY OF THE BLACKOUT PERIOD IMMEDIATELY UPON KNOWLEDGE
      THAT SUCH A BLACKOUT PERIOD (WITHOUT INDICATING THE NATURE OF SUCH
      POTENTIAL MATERIAL EVENT) WILL OCCUR AND SUCH NOTICE MUST BE ACKNOWLEDGED
      IN WRITING BY THE INVESTORS. FAILURE TO PROVIDE THE INVESTORS WITH SUCH
      NOTICE SHALL CONSTITUTE A REGISTRATION DEFAULT DURING THE ENTIRE
      APPLICABLE PERIOD THAT A REGISTRATION STATEMENT IS SUSPENDED. Compliance
      by the Company with this Section 3(h) will not result in or be deemed a
      breach of any of the Company's obligations set forth in the Purchase
      Agreement not to disclose non-public information to the Investors.

            (i) "Potential Material Event" means any of the following: (a) the
      possession by the Company of material information not ripe for disclosure
      in a registration statement, as determined in good faith by the Chief
      Executive Officer or the Board of Directors of the Company that disclosure
      of such information in a Registration Statement would be detrimental to
      the business and affairs of the Company; or (b) any material engagement or
      activity by the Company which would, in the good faith determination of
      the Chief Executive Officer or the Board of Directors of the Company, be
      adversely affected by disclosure in a registration statement at such time,
      which determination shall be accompanied by a good faith determination by
      the Chief Executive Officer or the Board of Directors of the Company that
      the applicable Registration Statement would be materially misleading
      absent the inclusion of such information.

      Section 4. Cooperation with Company. The Investors will cooperate with the
Company in all respects in connection with this Agreement, including timely
supplying all information reasonably requested by the Company (which shall
include all information regarding the Investors and proposed manner of sale of
the Registrable Securities required to be disclosed in any Registration
Statement) and executing and returning all documents reasonably requested in
connection with the registration and sale of the Registrable Securities and
entering into and performing their obligations under any underwriting agreement,
if the offering is an underwritten offering, in usual and customary form, with
the managing underwriter or underwriters of such underwritten offering. Nothing
in this Agreement shall obligate any Investor to consent to be named as an
underwriter in any Registration Statement unless the SEC or applicable law
requires the Investor to be named. The obligation of the Company to register the
Registrable Securities shall be absolute and unconditional as to those
Securities which the SEC will permit to be registered without naming the
Investors as underwriters. Any delay or delays caused by the Investors by
failure to cooperate as required hereunder shall not constitute a Registration
Default.

      Section 5. Registration Procedures. If and whenever the Company is
required by any of the provisions of this Agreement to effect the registration
of any of the Registrable Securities under the Act, the Company shall (except as
otherwise provided in this Agreement), as expeditiously as possible, subject to
the Investors' assistance and cooperation as reasonably required with respect to
each Registration Statement:

            (a) (i) prepare and file with the SEC such amendments and
      supplements to the Registration Statements and the prospectus used in
      connection therewith as may be necessary to keep such Registration
      Statement effective and to comply with the provisions of the Act with
      respect to the sale or other disposition of all Registrable Securities
      covered by such Registration Statement whenever the Investors shall desire
      to sell or otherwise dispose of the same (including prospectus supplements
      with respect to the sales of Registrable Securities from time to time in
      connection with a registration statement pursuant to Rule 415 promulgated
      under the Act) and (ii) take all lawful action such that each of (A) the
      Registration Statements and any amendments thereto do not, when they
      becomes effective, contain an 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 under which
      they were made, not misleading and (B) the prospectus forming part of the
      Registration Statements, and any amendment or supplement thereto, does not
      at any time during the Registration Period include an 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 under which they were made, not misleading;

            (b) (i) prior to the filing with the SEC of any Registration
      Statement (including any amendments thereto) and the distribution or
      delivery of any prospectus (including any supplements thereto), provide
      draft copies thereof to the Investors as required by Section 3(d) and
      reflect in such documents all such comments as the Investors (and their
      counsel) reasonably may propose respecting the Selling Shareholders and
      Plan of Distribution sections (or equivalents); (ii) furnish to each
      Investor such numbers of copies of a prospectus including a preliminary
      prospectus or any amendment or supplement to any prospectus, as
      applicable, in conformity with the requirements of the Act, and such other
      documents, as such Investor may reasonably request in order to facilitate
      the public sale or other disposition of the Registrable Securities owned
      by such Investor; and (iii) provide to each Investor copies of any
      comments and communications from the SEC relating to any Registration
      Statement, if lawful to do so;

            (c) register and qualify the Registrable Securities covered by any
      Registration Statement under such other securities or blue sky laws of
      such jurisdictions as the Investors shall reasonably request (subject to
      the limitations set forth in Section 3(d) above), and do any and all other
      acts and things which may be necessary or advisable to enable each
      Investor to consummate the public sale or other disposition in such
      jurisdiction of the Registrable Securities owned by such Investor;

            (d) list such Registrable Securities on the Principal Market, if the
      listing of such Registrable Securities is then permitted under the rules
      of such Principal Market;

            (e) notify each Investor at any time when a prospectus relating
      thereto covered by any Registration Statement is required to be delivered
      under the Act, of the happening of any event of which it has knowledge as
      a result of which the prospectus included in any 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 not misleading in the light of the
      circumstances then existing, subject to Section 3(h), and the Company
      shall prepare and file a curative amendment under Section 5(a) as quickly
      as commercially possible and during such period, the Investors shall not
      make any sales of Registrable Securities pursuant to a Registration
      Statement and during such period; provided, however, any period during
      which the Investors are precluded from making sales of the Registrable
      Securities shall be included in the 20 calendar day period in Section 3(h)
      and any such days herein which exceed, or cause the Company to exceed,
      such 20 calendar day period shall be deemed a Registration Default and the
      Company shall be subject to Liquidated Damages as set forth in Section
      3(f).

            (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 any stop order or other suspension of the
      effectiveness of a Registration Statement at the earliest possible time
      and take all lawful action to effect the withdrawal, recession or removal
      of such stop order or other suspension;

            (g) cooperate with the Investors to facilitate the timely
      preparation and delivery of certificates for the Registrable Securities to
      be offered pursuant to a 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 reasonably may request and
      registered in such names as the Investors may request; and, within 4
      Trading Days after a Registration Statement which includes Registrable
      Securities is declared effective by the SEC, deliver and cause legal
      counsel selected by the Company to deliver to the transfer agent for the
      Registrable Securities (with copies to the Investors) an appropriate
      instruction and, to the extent necessary, an opinion of such counsel;

            (h) take all such other lawful actions reasonably necessary to
      expedite and facilitate the disposition by the Investors of their
      Registrable Securities in accordance with the intended methods therefor
      provided in the prospectus which are customary for issuers to perform
      under the circumstances;

            (i) in the event of an underwritten offering, promptly include or
      incorporate in a prospectus supplement or post-effective amendment to a
      Registration Statement such information as the managers reasonably agree
      should be included therein and to which the Company does not reasonably
      object and make all required filings of such prospectus supplement or
      post-effective amendment as soon as practicable after it is notified of
      the matters to be included or incorporated in such Prospectus supplement
      or post-effective amendment; and

            (j)   maintain  a  transfer  agent and  registrar  for its  Common
      Stock.

            Section 6.  Indemnification.

            (a) To the maximum extent permitted by law, the Company agrees to
      indemnify and hold harmless the Investors and each person, if any, who
      controls an Investor within the meaning of the Securities Act (each a
      "Distributing Investor") against any losses, claims, damages or
      liabilities, joint or several (which shall, for all purposes of this
      Agreement, include, but not be limited to, all reasonable costs of defense
      and investigation and all reasonable attorneys' fees and expenses), to
      which the Distributing Investor may become subject, under the Securities
      Act or otherwise, insofar as such losses, claims, damages or liabilities
      (or actions in respect thereof) arise out of or are based upon any untrue
      statement or alleged untrue statement of any material fact contained in
      any Registration Statement, or any related final prospectus or amendment
      or supplement thereto, or arise out of or are based upon 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;
      provided, however, that the Company will not be liable in any such case to
      the extent, and only to the extent, that any such loss, claim, damage or
      liability arises out of or is based upon an untrue statement or alleged
      untrue statement or omission or alleged omission made in such Registration
      Statement, preliminary prospectus, final prospectus or amendment or
      supplement thereto in reliance upon, and in conformity with, written
      information furnished to the Company by the Distributing Investor, its
      counsel, affiliates or any underwriter, specifically for use in the
      preparation thereof or by such Investor's failure to deliver to the
      purchaser a copy of the most recent prospectus (including any amendments
      or supplements thereto). This indemnity agreement will be in addition to
      any liability, which the Company may otherwise have.

            (b) To the maximum extent permitted by law, each Distributing
      Investor agrees that it will indemnify and hold harmless the Company, and
      each officer and director of the Company or person, if any, who controls
      the Company within the meaning of the Securities Act, against any losses,
      claims, damages or liabilities (which shall, for all purposes of this
      Agreement, include, but not be limited to, all reasonable costs of defense
      and investigation and all reasonable attorneys' fees and expenses) to
      which the Company or any such officer, director or controlling person may
      become subject under the Securities Act or otherwise, insofar as such
      losses, claims, damages or liabilities (or actions in respect thereof)
      arise out of or are based upon any untrue statement or alleged untrue
      statement of any material fact contained in any Registration Statement, or
      any related final prospectus or amendment or supplement thereto, or arise
      out of or are based upon the omission or the alleged omission to state
      therein a material fact required to be stated therein or necessary to make
      the statements therein not misleading, but in each case only to the extent
      that such untrue statement or alleged untrue statement or omission or
      alleged omission was made in such Registration Statement, final prospectus
      or amendment or supplement thereto in reliance upon, and in conformity
      with, written information furnished to the Company by such Distributing
      Investor, its counsel, affiliates or any underwriter, specifically for use
      in the preparation thereof. This indemnity agreement will be in addition
      to any liability, which the Distributing Investor may otherwise have.
      Notwithstanding anything to the contrary herein, the Distributing Investor
      shall be liable under this Section 6(b) for only that amount as does not
      exceed the net proceeds to such Distributing Investor as a result of the
      sale of Registrable Securities pursuant to any Registration Statement.

            (c) Promptly after receipt by an indemnified party under this
      Section 6 of notice of the commencement of any action against such
      indemnified party, such indemnified party will, if a claim in respect
      thereof is to be made against the indemnifying party under this Section 6,
      notify the indemnifying party in writing of the commencement thereof; but
      the omission so to notify the indemnifying party will not relieve the
      indemnifying party from any liability which it may have to any indemnified
      party except to the extent the failure of the indemnified party to provide
      such written notification actually prejudices the ability of the
      indemnifying party to defend such action. In case any such action is
      brought against any 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 party of its election so to assume
      the defense thereof, the indemnifying party will not be liable to such
      indemnified party under this Section 6 for any legal or other expenses
      subsequently incurred by such indemnified party in connection with the
      defense thereof other than reasonable costs of investigation, unless the
      indemnifying party shall not pursue the action to its final conclusion.
      The indemnified parties as a group shall have the right to employ one
      separate counsel in any such action and to participate in the defense
      thereof, but the fees and 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 party unless (i) the employment of such counsel has been
      specifically authorized in writing by the indemnifying party, or (ii) the
      named parties to any such action (including any impleaded parties) include
      both the indemnified party and the indemnifying party and the indemnified
      party shall have been advised by its counsel that there may be one or more
      legal defenses available to the indemnifying party different from or in
      conflict with any legal defenses which may be available to the indemnified
      party or any other indemnified party (in which case the indemnifying party
      shall not have the right to assume the defense of such action on behalf of
      such indemnified party, it being understood, however, that the
      indemnifying party shall, in connection with any one such action or
      separate but substantially similar or related actions in the same
      jurisdiction arising out of the same general allegations or circumstances,
      be liable only for the reasonable fees and expenses of one separate firm
      of attorneys for the indemnified party, which firm shall be designated in
      writing by the indemnified party). No settlement of any action against an
      indemnified party shall be made without the prior written consent of the
      indemnified party, which consent shall not be unreasonably withheld so
      long as such settlement includes a full release of claims against the
      indemnified party.

            All fees and expenses of the indemnified party (including reasonable
      costs of defense and investigation in a manner not inconsistent with this
      Section and all reasonable attorneys' fees and expenses) shall be paid to
      the indemnified party, as incurred, within ten (10) Trading Days of
      written notice thereof to the indemnifying party; provided, that the
      indemnifying party may require such indemnified party to undertake to
      reimburse all such fees and expenses to the extent it is finally
      judicially determined that such indemnified party is not entitled to
      indemnification hereunder.

      Section 7. Contribution. In order to provide for just and equitable
contribution under the Securities Act in any case in which (i) the indemnified
party makes a claim for indemnification pursuant to Section 6 hereof but is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 6 hereof provide
for indemnification in such case, or (ii) contribution under the Securities Act
may be required on the part of any indemnified party, then the Company and the
applicable Distributing Investor shall contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (which shall, for
all purposes of this Agreement, include, but not be limited to, all reasonable
costs of defense and investigation and all reasonable attorneys' fees and
expenses), in either such case (after contribution from others) on the basis of
relative fault as well as any other relevant equitable considerations. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company on the one hand or the applicable Distributing Investor on the other
hand, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Distributing Investor agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to in this Section 7. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this Section 7
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

      Notwithstanding any other provision of this Section 7, in no event shall
any Investor be required to undertake liability to any person under this Section
7 for any amounts in excess of the dollar amount of the proceeds received by
such Investor from the sale of such Investor's Registrable Securities (after
deducting any fees, discounts and commissions applicable thereto) pursuant to
any Registration Statement under which such Registrable Securities are
registered under the Securities Act.

      Section 8. Notices. All notices, demands, requests, consents, approvals,
and other communications required or permitted hereunder shall be in writing
and, unless otherwise specified herein, shall be (i) hand delivered, (ii)
deposited in the mail, registered or certified, return receipt requested,
postage prepaid, (iii) delivered by reputable air courier service with charges
prepaid, or (iv) transmitted by facsimile, addressed as set forth in the
Purchase Agreement or to such other address as such party shall have specified
most recently by written notice. Any notice or other communication required or
permitted to be given hereunder shall be deemed effective (a) upon hand delivery
or delivery by facsimile, with accurate confirmation generated by the
transmitting facsimile machine, at the address or number designated below (if
delivered on a business day during normal business hours where such notice is to
be received), or the first business day following such delivery (if delivered
other than on a business day during normal business hours where such notice is
to be received) or (b) on the first business day following the date of sending
by reputable courier service, fully prepaid, addressed to such address, or (c)
upon actual receipt of such mailing, if mailed. Either party hereto may from
time to time change its address or facsimile number for notices under this
Section 8 by giving at least ten (10) days' prior written notice of such changed
address or facsimile number to the other party hereto.

      Section 9. Assignment. Neither this Agreement nor any rights of the
Company hereunder may be assigned by the Company to any other person. The
Investor's shall not assign this Agreement without the consent of the Company,
which consent shall not be unreasonably withheld. The provisions of this
Agreement shall inure to the benefit of, and be enforceable by, any permitted
transferee of any of the Convertible Subordinated Debentures and Warrants
purchased or acquired by any Investor hereunder with respect to the Convertible
Subordinated Debentures and Warrants held by such person. Notwithstanding
anything to the contrary herein, in no event shall an Investor assign this
Agreement to any persons, entity or company that, in the reasonable judgment of
the Company, are in direct competition with the Company, including but not
limited to, persons, entities or companies in the telecommunications industry,
data communications industry or the business of manufacturing optical fiber or
preform.

      Section 10. Additional Covenants of the Company. The Company agrees that,
for so long as it shall be required to maintain the effectiveness of any
Registration Statement, it shall file all reports and information required to be
filed by it with the SEC in a timely manner and take all such other action so as
to maintain such eligibility for the use of such form.

      Section 11. Counterparts/Facsimile. This Agreement may be executed in two
or more counterparts, each of which shall constitute an original, but all of
which, when together shall constitute but one and the same instrument, and shall
become effective when one or more counterparts have been signed by each party
hereto and delivered to the other parties. In lieu of the original, a facsimile
transmission or copy of the original shall be as effective and enforceable as
the original.

      Section 12. Remedies. The remedies provided in this Agreement are
cumulative and not exclusive of any remedies provided by law. If any term,
provision, covenant or restriction of this Agreement is held by a court of
competent jurisdiction to be invalid, illegal, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions set forth herein
shall remain in full force and effect and shall in no way be affected, impaired
or invalidated, and the parties hereto shall use their best efforts to find and
employ an alternative means to achieve the same or substantially the same result
as that contemplated by such term, provision, covenant or restriction.

      Section 13. Conflicting Agreements. The Company shall not enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the holders of Registrable Securities in this Agreement or otherwise
prevents the Company from complying with all of its obligations hereunder.

      Section 14. Headings. The headings in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.

      Section 15. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made in New York by persons domiciled in New York City and without
regard to its principles of conflicts of laws. The Company and each of the
Investors agree to submit themselves to the in personam jurisdiction of the
state and federal courts situated within the Southern District of the State of
New York with regard to any controversy arising out of or relating to this
Agreement. The non-prevailing party to any dispute hereunder shall pay the
expenses of the prevailing party, including reasonable attorneys' fees, in
connection with any such dispute.

Re:   Convertible Subordinated Debentures and Warrants Purchase Agreement
      between the Investors Signatory thereto and FiberCore, Inc. (the
      "Purchase Agreement").

Ladies and Gentlemen:

      This opinion is furnished to you pursuant to the Purchase Agreement by and
between the investors signatory thereto (the "Investors") and FiberCore, Inc., a
Nevada corporation (the "Company"), dated as of the date hereof (the "Purchase
Agreement"), which provides for the issuance and sale by the Company of, in the
aggregate, $9,000,000 principal amount of Convertible Subordinated Debentures
and Warrants to purchase shares of the Company's Common Stock. ALL TERMS USED
HEREIN HAVE THE MEANINGS DEFINED FOR THEM IN THE PURCHASE AGREEMENT UNLESS
OTHERWISE DEFINED HEREIN.

      We have acted as special Nevada counsel for the Company in connection with
the transactions contemplated by the Purchase Agreement. In connection with such
representation, we have reviewed copies of the following documents:

1.    the Convertible Subordinated Debentures issued to each Investor;

2.    the Warrants issued to each Investor;

3.    the Registration Rights Agreement between the Investors and the Company,
      dated as of the date hereof (the "Registration Rights Agreement");

4.    Articles of Incorporation of the Company (as amended, the "Articles"),
      certified as of January 10, 2002, by the Nevada Secretary of State and
      certified as of the date hereof by the Chief Financial Officer and
      Treasurer of the Company;

5.    Bylaws of the Company (as amended, the "Bylaws"), certified as of the date
      hereof by the Chief Financial Officer and Treasurer of the Company; and

6.    Resolutions of the Company's board of directors adopted December 28, 2001,
      certified as of the date hereof by the Chief Financial Officer and
      Treasurer of the Company.

      Documents 1-3 above, along with the Purchase Agreement, are referred to
herein as the "Agreements." Unless otherwise listed above, we have not reviewed,
and express no opinion as to, any instrument or agreement referred to or
incorporated by reference in the Agreements.

      We have also examined originals or copies certified or otherwise
identified to our satisfaction of such other corporate records, certificates of
governmental officials and documents as we have deemed necessary or appropriate
for the purpose of this opinion. We have relied upon the certificates of all
public officials and corporate officers with respect to the accuracy of all
matters contained therein.

      We have assumed the authenticity of all documents submitted to us as
originals, the genuineness of all signatures, the legal capacity of natural
persons and the conformity to originals of all copies of all documents submitted
to us.

      Nothing herein shall be deemed an opinion as to the laws of any
jurisdiction other than the State of Nevada.

      As used herein, the phrase "the best of our knowledge" means only such
actual knowledge as we have obtained from consultation with attorneys presently
in our firm whom we have determined are likely, in the ordinary course of their
respective duties, to have knowledge of the matters covered by such opinions.
Except as expressly provided otherwise herein, we have not conducted any other
investigation or review in connection with the opinions rendered herein,
including without limitation a review of any of our files or the files of the
Company.

      Based upon and subject to the foregoing, and subject to the
qualifications, limitations, restrictions and assumptions set forth below, we
are of the opinion that:

      1. The Company is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Nevada and has all requisite
corporate power and authority to carry on its business and to own, lease and
operate its properties and assets as described in the Company's year 2000 Form
10K filed with the United States Securities and Exchange Commission on April 2,
2001. To the best of our knowledge, the Company does not have any subsidiaries
and does not own more than fifty percent (50%) of the outstanding capital stock
of or control any other business entity other than as disclosed in such Form
10K.

      2. The Company has the requisite corporate power and authority to enter
into and perform its obligations under the Agreements and to issue the
Convertible Subordinated Debentures and Warrants and the Conversion Shares and
the Warrant Shares. The execution and delivery of the Agreements by the Company
and the consummation by it of the transactions contemplated thereby have been
duly authorized by all necessary corporate action and no further consent or
authorization of the Company or its Board of Directors or stockholders is
required. Each of the Agreements has been duly executed and delivered, and the
Convertible Subordinated Debentures and Warrants have been duly executed, issued
and delivered by the Company.

      3. The execution, delivery and performance of the Agreements by the
Company and the consummation by the Company of the transactions contemplated
thereby, including, without limitation, the issuance of the Convertible
Subordinated Debentures, the Warrants, the Conversion Shares and the Warrant
Shares, do not and will not (i) result in a violation of its Articles or Bylaws;
or (ii) result in a violation of any Nevada law, rule or regulation applicable
to the Company or by which any property or asset of the Company is bound or
affected, except for such violations as would not, individually or in the
aggregate, have a Material Adverse Effect. To the best of our knowledge, the
Company is not in violation of any terms of its Articles or Bylaws.

      4. When issued and paid for in accordance with the Purchase Agreement, the
Conversion Shares and Warrant Shares will be duly and validly issued, fully paid
and nonassessable, and free of any liens, encumbrances and preemptive or similar
rights contained in the Articles or Bylaws or, to the best of our knowledge, in
any agreement to which the Company is party. In giving this Opinion we have
assumed that at the time of an issuance of Conversion Shares or Warrant Shares,
the Company will have a sufficient number of authorized but unissued (and not
otherwise reserved) shares of its common stock available to accommodate such
issuance.

      5. We have not been engaged to devote substantive attention to any claims,
actions, suits, proceedings or investigations that are pending against the
Company or its properties, or against any officer or director of the Company in
his or her capacity as such. To the best of our knowledge, the Company is not a
party to or subject to the provisions of any order, writ, injunction, judgment
or decree of any court or government agency or instrumentality.

      6. The authorized capital stock of the Company consists of 100,000,000
shares of Common Stock, par value per share of $.001, of which 61,481,139 shares
are issued and outstanding, and 10,000,000 shares of preferred stock of which 1
share of Series A is issued and outstanding. In opining as to the number of
shares outstanding, we have relied solely upon a certificate of the Company's
Treasurer.

      This opinion is intended solely for the use of the Investors in connection
with the transactions referred to above. It may not be relied upon by any other
person or for any other purpose, or reproduced or filed publicly by any person,
without the written consent of this firm.

                                                Very truly yours,

                                                Lionel Sawyer & Collins

Re:   Convertible Subordinated Debentures and Warrants Purchase
      Agreement

Ladies and Gentlemen:

            We have acted as special counsel to the Company in connection with
the Convertible Subordinated Debentures and Warrants Purchase Agreement, dated
as of January 15, 2002 (the "Agreement"), between FiberCore, Inc. (the
"Company"), and Riverview Group, LLC and Laterman & Co. (each an "Investor" and
together the "Investors"), which provides for the issuance and sale by the
Company in the aggregate, of up to $9,000,000 principal amount of Convertible
Subordinated Debentures (the "Debentures") and Warrants to purchase a number
shares of the Company's Common Stock to be determined in accordance with the
Agreement (the "Warrants"). Capitalized terms used herein but not defined herein
have the respective meanings given to them in the Agreement. We are rendering
this opinion letter to you at the request of the Company pursuant to Section
1.1(b)(viii) of the Agreement.

            In rendering the opinions set forth below, we have examined and
relied upon the originals, copies or specimens, certified or otherwise
identified to our satisfaction, of the Transaction Documents (as defined below)
and such certificates, corporate and public records, agreements and instruments
and other documents, including, among other things, the documents delivered on
the date hereof, as we have deemed appropriate as a basis for the opinions
expressed below. In such examination we have assumed the genuineness of all
signatures, the authenticity of all documents, agreements and instruments
submitted to us as originals, the conformity to original documents, agreements
and instruments of all documents, agreements and instruments submitted to us as
copies or specimens, the authenticity of the originals of such documents,
agreements and instruments submitted to us as copies or specimens, and the
accuracy of the matters set forth in the documents, agreements and instruments
we reviewed. As to any facts material to such opinions that were not known to
us, we have relied upon statements and representations of the Company, officers
and other representatives of the Company, and of public officials. Except as
expressly set forth herein, we have not undertaken any independent investigation
(including, without limitation, conducting any review, search or investigation
of any public files, records or dockets) to determine the existence or absence
of the facts that are material to our opinions, and no inference as to our
knowledge concerning such facts should be drawn from our reliance on the
representations of the Company in connection with the preparation and delivery
of this letter.

            In particular, we have examined and relied upon:

            1. the Agreement;

            2. the Debentures issuable at the First Closing;

            3. the Warrants issuable at the First Closing; and

            4. the Registration Rights Agreement between the Investors, and the
      Company, dated January 15, 2002 (the "Registration Rights Agreement").

Items 1 to 4 above are referred to in this letter as the "Transaction
Documents". References in this letter to "Applicable Laws" shall mean those
laws, rules and regulations of the State of New York and of the United States of
America which, in our experience, are normally applicable to transactions of the
type contemplated by the Transaction Documents. References in this letter to the
term "Governmental Authorities" means executive, legislative, judicial,
administrative or regulatory bodies of the State of New York or the United
States of America. References in this letter to the term "Governmental Approval"
means any consent, approval, license, authorization or validation of, or filing,
recording or registration with, any Governmental Authority pursuant to
Applicable Laws.

            We have also assumed (other than with respect to the Company) that
all documents, agreements and instruments have been duly authorized, executed
and delivered by all parties thereto, that all such parties had the power and
legal right to execute and deliver all such documents, agreements and
instruments, and that such documents, agreements and instruments are valid,
binding and enforceable obligations of such parties. As used herein, "to our
knowledge", "known to us" or words of similar import mean the actual knowledge,
without independent investigation, of any lawyer in our firm actively involved
in the transactions contemplated by the Agreement.

            We express no opinion concerning the laws of any jurisdiction other
than the laws of the State of New York and, to the extent expressly referred to
in this opinion letter, the federal laws of the United States of America. With
respect to matters of Nevada law, we call your attention to the opinion dated as
of January 15, 2002, of Lionel Sawyer & Collins and our opinion is subject to
the same assumptions, qualifications and limitations with respect to such
matters as are contained in such opinion.

            Based upon and subject to the foregoing, we are of the opinion that:

            1. Each of the Transaction Documents executed by the Company
      constitutes a legal, valid and binding agreement of the Company,
      enforceable against the Company in accordance with its terms, subject to
      applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
      moratorium, receivership or other laws relating to or affecting creditors'
      rights generally, and to general principles of equity (regardless of
      whether enforcement is sought in a proceeding at law or in equity), and
      except that the enforcement of rights with respect to indemnification and
      contribution obligations and provisions (a) purporting to waive or limit
      rights to oral amendments to written agreements or rights of set off, (b)
      relating to submission of jurisdiction, venue or service of process, or
      (c) relating to liquidated damages, may be limited by applicable law or
      considerations of public policy.

            2. The execution and delivery by the Company of the Transaction
      Documents, and the performance by the Company of its obligations
      thereunder, do not breach or result in a violation of, or default under
      (i) any indenture, mortgage, deed of trust, agreement or instrument
      identified on Schedule A attached hereto, or (ii) any judgment, decree or
      order known to us which is applicable to the Company and, pursuant to any
      Applicable Laws, is issued by any Governmental Authority having
      jurisdiction over the Company or its properties.

            3. We have not been engaged to devote substantive attention to any
      claims, actions, suits, proceedings or investigations that are pending
      against the Company or its properties, or against any officer or director
      of the Company in his or her capacity as such. To our knowledge, there is
      no legal or governmental action, investigation or proceeding pending or
      threatened against the Company (a) asserting the invalidity of the
      Transaction Documents, (b) seeking to prevent the consummation of any of
      the transactions provided for in the Transaction Documents, or (c) which
      would materially and adversely affect the ability of the Company to
      perform its obligations under, or the validity or enforceability (with
      respect to the Company) of, the Transaction Documents. For purposes of the
      opinion set forth in this paragraph, we have not regarded any legal or
      governmental actions, investigations or proceedings to be "threatened"
      unless the potential litigant or Governmental Authority has communicated
      in writing to the Company a present intention to initiate such actions,
      investigations or proceedings against the Company.

            4. Assuming the accuracy of the representations and warranties in
      the Agreement and compliance with the terms and provisions of the the
      Agreement, it is not necessary in connection with the offer and sale of
      the Securities by the Company to the Investors, under the circumstances
      contemplated by the Agreement, to register the Convertible Subordinated
      Debentures or the Warrants issued at the First Closing under the
      Securities Act of 1933.

            We are furnishing this letter to you solely for your benefit in
connection with the transactions referred to herein. This letter is not to be
relied upon, used, circulated, quoted or otherwise referred to by any other
person or entity or for any other purpose without our prior written consent. In
addition, we disclaim any obligation to update this letter for changes in fact
or law, or otherwise.

                                                Very truly yours,

            To Purchase _______________ Shares of Common Stock of

                               FIBERCORE, INC.

            THIS CERTIFIES that, for value received, _____________ (the
"Holder"), is entitled, upon the terms and subject to the limitations on
exercise and the conditions hereinafter set forth, at any time on or after
_______, 2002 (the "Initial Exercise Date") and on or prior to the close of
business on the fourth anniversary of the Initial Exercise Date (the

Fibercore, Inc., a corporation incorporated in the State of Nevada (the
"Company"), up to ____________ shares (the "Warrant Shares") of Common Stock,
par value $.001 per share, of the Company (the "Common Stock"). The purchase
price of one share of Common Stock (the "Exercise Price") under this Warrant
shall be $____, subject to adjustment hereunder. The Exercise Price and the
number of Warrant Shares for which the Warrant is exercisable shall be subject
to adjustment as provided herein. Capitalized terms used and not otherwise

<PAGE>

            1. Title to Warrant. Prior to the Termination Date and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
Holder in person or by duly authorized attorney, upon surrender of this Warrant
together with the Assignment Form annexed hereto properly endorsed.

            2. Authorization of Shares. The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this
Warrant, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges in respect of the issue thereof (other
than taxes in respect of any transfer occurring contemporaneously with such
issue).

            3. Exercise of Warrant.

               (a) Except as provided in Section 4 herein, exercise of the
      purchase rights represented by this Warrant may be made at any time or
      times on or after the Initial Exercise Date and on or before the
      Termination Date by the surrender of this Warrant and the Notice of
      Exercise Form annexed hereto duly executed, at the office of the Company
      (or such other office or agency of the Company as it may designate by
      notice in writing to the registered Holder at the address of such Holder
      appearing on the books of the Company) and upon payment of the Exercise
      Price of the shares thereby purchased by wire transfer or cashier's check
      drawn on a United States bank, the Holder shall be entitled to receive a
      certificate for the number of Warrant Shares so purchased. Certificates
      for shares purchased hereunder shall be delivered to the Holder within
      four (4) Trading Days after the date on which this Warrant shall have been
      exercised as aforesaid. This Warrant shall be deemed to have been
      exercised and such certificate or certificates shall be deemed to have
      been issued, and Holder or any other person so designated to be named
      therein shall be deemed to have become a holder of record of such shares
      for all purposes, as of the date the Warrant has been exercised by payment
      to the Company of the Exercise Price and all taxes required to be paid by
      the Holder, if any, pursuant to Section 5 prior to the issuance of such
      shares, have been paid. If the Company fails to deliver to the Holder a
      certificate or certificates representing the Warrant Shares pursuant to
      this Section 3(a) by the third Trading Day after the date of exercise,
      then the Holder will have the right to rescind such exercise. In addition
      to any other rights available to the Holder, (i) if the Holder sells the
      shares it has exercised and the Holder has provided the Company evidence
      of such sale reasonably satisfactory to the Company (the "Sale"), and (ii)
      if the Company fails to deliver to the Holder such certificate or
      certificates by the 5th Trading Day after the date the Holder exercises
      this Warrant, and if after such 5th Trading Day the Holder purchases (in
      an open market transaction or otherwise) Common Stock to deliver in
      satisfaction of a sale by such Holder of the Warrant Shares which the
      Holder anticipated receiving upon such exercise (a "Buy-In"), then the
      Company shall (A) pay in cash to the Holder (in addition to any remedies
      available to or elected by the Holder) the amount by which (x) the
      Holder's total purchase price (including brokerage commissions, if any)
      for the Common Stock so purchased exceeds (y) the product of (1) the
      aggregate number of shares of Common Stock that such Holder anticipated
      receiving from the exercise at issue multiplied by (2) the per share price
      at which the Common Stock was sold pursuant to the Sale, and (B) at the
      option of the Holder, (x) deliver the Warrant Shares not yet delivered
      pursuant to such exercise and subject to this provision, or (y) reinstate
      the portion of this Warrant for which such exercise was not honored. For
      example, if the Holder purchases Common Stock having a total purchase
      price of $11,000 to cover a Buy-In with respect to an attempted exercise
      of this Warrant with respect to which the market price of the Warrant
      Shares on the date of exercise was a total of $10,000, the Company shall
      be required to pay the Holder $1,000. The Holder shall provide the Company
      written notice indicating the amounts payable to the Holder in respect of
      the Buy-In and the basis for determining such amount. Nothing herein shall
      limit the Holder's right to pursue any other remedies available to it
      hereunder, at law or in equity, including, without limitation, a decree of
      specific performance and/or injunctive relief with respect to the
      Company's failure to timely deliver certificates representing shares of
      Common Stock upon exercise of this Warrant as required pursuant to the
      terms hereof.

               (b) If this Warrant shall have been exercised in part, the
      Company shall, at the time of delivery of the certificate or certificates
      representing Warrant Shares, deliver to Holder a new Warrant evidencing
      the rights of Holder to purchase the unpurchased Warrant Shares called for
      by this Warrant, which new Warrant shall in all other respects be
      identical with this Warrant.

               (c) Notwithstanding anything herein to the contrary, in no event
      shall the Holder be permitted to exercise this Warrant for Warrant Shares
      to the extent that (i) the number of shares of Common Stock owned by such
      Holder (other than Warrant Shares issuable upon exercise of this Warrant)
      plus (ii) the number of Warrant Shares issuable upon exercise of this
      Warrant, would be equal to or exceed 4.9999% of the number of shares of
      Common Stock then issued and outstanding, including shares issuable upon
      exercise of this Warrant held by such Holder after application of this
      Section 3(c). As used herein, beneficial ownership shall be determined in
      accordance with Section 13(c) of the Exchange Act. To the extent that the
      limitation contained in this Section 3(c) applies, the determination of
      whether this Warrant is exercisable (in relation to other securities owned
      by the Holder) and of which a portion of this Warrant is exercisable shall
      be in the sole discretion of such Holder, and the submission of a Notice
      of Exercise shall be deemed to be such Holder's determination of whether
      this Warrant is exercisable (in relation to other securities owned by such
      Holder) and of which portion of this Warrant is exercisable, in each case
      subject to such aggregate percentage limitation, and the Company shall
      have no obligation to verify or confirm the accuracy of such
      determination. Nothing contained herein shall be deemed to restrict the
      right of a Holder to exercise this Warrant into Warrant Shares at such
      time as such exercise will not violate the provisions of this Section
      3(c). The provisions of this Section 3(c) may be waived by the Holder
      upon, at the election of the Holder, not less than 61 days' prior notice
      to the Company, and the provisions of this Section 3(c) shall continue to
      apply until such 61st day (or such later date, as determined by the
      Holder, as may be specified in such notice of waiver). No exercise of this
      Warrant in violation of this Section 3(c) but otherwise in accordance with
      this Warrant shall affect the status of the Warrant Shares as validly
      issued, fully-paid and nonassessable.

               (d) At anytime beginning one (1) year from the date this Warrant
      is issued, in the event that the Registration Statement registering the
      Warrant Shares issuable hereunder is not then effective, this Warrant may
      also be exercised by means of a "cashless exercise" in which the Holder
      shall be entitled to receive a certificate for the number of Warrant
      Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A),
      where:

               (A) = the average of the high and low trading prices per share of
                     Common Stock on the Trading Day preceding the date of such
                     election;

               (B) = the Exercise Price of the Warrants; and

               (X) = the number of Warrant Shares issuable upon exercise of the
                     Warrants in accordance with the terms of this Warrant.

            4. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

            5. Charges, Taxes and Expenses. Issuance of certificates for Warrant
Shares shall be made without charge to the Holder for any issue or transfer tax
or other incidental expense in respect of the issuance of such certificate, all
of which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event certificates for
Warrant Shares are to be issued in a name other than the name of the Holder,
this Warrant when surrendered for exercise shall be accompanied by the
Assignment Form attached hereto duly executed by the Holder; and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

            6. Closing of Books. The Company will not close its stockholder
books or records in any manner which prevents the timely exercise of this
Warrant.

            7. Transfer, Division and Combination.

               (a) Subject to compliance with any applicable securities laws,
      transfer of this Warrant and all rights hereunder, in whole or in part,
      shall be registered on the books of the Company to be maintained for such
      purpose, upon surrender of this Warrant at the principal office of the
      Company, together with a written assignment of this Warrant substantially
      in the form attached hereto duly executed by the Holder or its agent or
      attorney and funds sufficient to pay any transfer taxes payable upon the
      making of such transfer. In the event that the Holder wishes to transfer a
      portion of this Warrant, the Holder shall transfer at least 100,000 shares
      underlying this Warrant to any such transferee. Upon such surrender and,
      if required, such payment, the Company shall execute and deliver a new
      Warrant or Warrants in the name of the assignee or assignees and in the
      denomination or denominations specified in such instrument of assignment,
      and shall issue to the assignor a new Warrant evidencing the portion of
      this Warrant not so assigned, and this Warrant shall promptly be
      cancelled. A Warrant, if properly assigned, may be exercised by a new
      holder for the purchase of Warrant Shares without having a new Warrant
      issued. Notwithstanding any provision herein, the Holder shall not sell,
      assign, pledge, encumber, or otherwise transfer this Warrant or any rights
      hereunder to any person or entity without the consent of the Company,
      which consent shall not be unreasonably withheld; provided, however, in no
      event shall the Holder assign this Warrant to any person, entity or
      company that, in the reasonable judgment of the Company, are in direct
      competition with the Company, including but not limited to, persons,
      entities or companies in the telecommunications industry, data
      communications industry or the business of manufacturing optical fiber or
      preform.

               (b) This Warrant may be divided or combined with other Warrants
      upon presentation hereof at the aforesaid office of the Company, together
      with a written notice specifying the names and denominations in which new
      Warrants are to be issued, signed by the Holder or its agent or attorney.
      Subject to compliance with Section 7(a), as to any transfer which may be
      involved in such division or combination, the Company shall execute and
      deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
      to be divided or combined in accordance with such notice.

               (c) The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
Section 7.

               (d) The Company agrees to maintain, at its aforesaid office,
books for the registration and the registration of transfer of the Warrants.

            8. No Rights as Shareholder until Exercise. This Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price, the Warrant Shares so purchased shall
be and be deemed to be issued to such Holder as the record owner of such shares
as of the close of business on the later of the date of such surrender or
payment.

            9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which shall
not include the posting of any bond), and upon surrender and cancellation of
such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

           10. Saturdays, Sundays, Holidays, etc. If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a Saturday,
Sunday or legal holiday.

           11. Adjustments of Exercise Price and Number of Warrant Shares.

               (a) Stock Splits, etc. The number and kind of securities
      purchasable upon the exercise of this Warrant and the Exercise Price shall
      be subject to adjustment from time to time upon the happening of any of
      the following. In case the Company shall (i) pay a dividend in shares of
      Common Stock or make a distribution in shares of Common Stock to holders
      of its outstanding Common Stock, (ii) subdivide its outstanding shares of
      Common Stock into a greater number of shares, (iii) combine its
      outstanding shares of Common Stock into a smaller number of shares of
      Common Stock, or (iv) issue any shares of its capital stock in a
      reclassification of the Common Stock, then the number of Warrant Shares
      purchasable upon exercise of this Warrant immediately prior thereto shall
      be adjusted so that the Holder shall be entitled to receive the kind and
      number of Warrant Shares or other securities of the Company which it would
      have owned or have been entitled to receive had such Warrant been
      exercised in advance thereof. Upon each such adjustment of the kind and
      number of Warrant Shares or other securities of the Company which are
      purchasable hereunder, the Holder shall thereafter be entitled to purchase
      the number of Warrant Shares or other securities resulting from such
      adjustment at an Exercise Price per Warrant Share or other security
      obtained by multiplying the Exercise Price in effect immediately prior to
      such adjustment by the number of Warrant Shares purchasable pursuant
      hereto immediately prior to such adjustment and dividing by the number of
      Warrant Shares or other securities of the Company resulting from such
      adjustment. An adjustment made pursuant to this paragraph shall become
      effective immediately after the effective date of such event retroactive
      to the record date, if any, for such event.

               (b) Anti-Dilution Provisions. During the Exercise Period, the
      Exercise Price and the number of Warrant Shares issuable hereunder and for
      which this Warrant is then exercisable pursuant to Section 1 hereof shall
      be subject to adjustment from time to time as provided in this Section
      11(b). In the event that any adjustment of the Exercise Price as required
      herein results in a fraction of a cent, such Exercise Price shall be
      rounded up or down to the nearest cent.

                  (i) Adjustment of Exercise Price. If and whenever the Company
            issues or sells, or in accordance with Section 8(b) hereof is deemed
            to have issued or sold, any shares of Common Stock for a
            consideration per share of less than the Set Price (as that term is
            defined in the Convertible Subordinated Debenture issued in
            connection herewith) or for no consideration (collectively, a
            "Dilutive Issuance"), then effective immediately upon the Dilutive
            Issuance, the Exercise Price will be reduced so that the Exercise
            Price in effect immediately following the Dilutive Issuance will be
            equal to the Exercise Price multiplied by a fraction, of which the
            denominator shall be the number of shares of the Common Stock
            (excluding treasury shares, if any) outstanding on the date of
            issuance of such Capital Share Equivalent plus the number of Capital
            Share Equivalents offered for subscription or purchase, and of which
            the numerator shall be the number of shares of the Common Stock
            (excluding treasury shares, if any) outstanding on the date of
            issuance of such Capital Share Equivalent plus the number of shares
            which the aggregate offering price of the total number of shares so
            offered would purchase at the Exercise Price.

                  (ii) Effect on Exercise Price of Certain Events. For purposes
            of determining the adjusted Exercise Price under Section 11(b)
            hereof, the following will be applicable:

                        (A) Issuance of Rights or Options. If the Company in any
                  manner issues or grants any warrants, rights or options,
                  whether or not immediately exercisable, to subscribe for or to
                  purchase Common Stock or other securities exercisable,
                  convertible into or exchangeable for Common Stock
                  (collectively "Convertible Securities") (such warrants, rights
                  and options to purchase Common Stock or Convertible Securities
                  are hereinafter referred to as "Options") and the price per
                  share for which Common Stock is issuable upon the exercise of
                  such Options is less than the Set Price (the Options so
                  priced, the "Below Set Price Options"), then the maximum total
                  number of shares of Common Stock issuable upon the exercise of
                  all such Below Set Price Options (assuming full exercise,
                  conversion or exchange of Convertible Securities, if
                  applicable) will, as of the date of the issuance or grant of
                  such Below Set Price Options, be deemed to be outstanding and
                  to have been issued and sold by the Company for such price per
                  share. For purposes of the preceding sentence, the "price per
                  share for which Common Stock is issuable upon the exercise of
                  such Below Set Price Options" is determined by dividing (i)
                  the total amount, if any, received or receivable by the
                  Company as consideration for the issuance or granting of all
                  such Below Set Price Options, plus the minimum aggregate
                  amount of additional consideration, if any, payable to the
                  Company upon the exercise of all such Below Set Price Options,
                  plus, in the case of Convertible Securities issuable upon the
                  exercise of such Below Set Price Options, the minimum
                  aggregate amount of additional consideration payable upon the
                  exercise, conversion or exchange thereof at the time such
                  Convertible Securities first become exercisable, convertible
                  or exchangeable, by (ii) the maximum total number of shares of
                  Common Stock issuable upon the exercise of all such Below Set
                  Price Options (assuming full conversion of Convertible
                  Securities, if applicable). No further adjustment to the
                  Exercise Price will be made upon the actual issuance of such
                  Common Stock upon the exercise of such Below Set Price Options
                  or upon the exercise, conversion or exchange of Convertible
                  Securities issuable upon exercise of such Below Set Price
                  Options.

                        (B) Issuance of Convertible Securities. If the Company
                  in any manner issues or sells any Convertible Securities,
                  whether or not immediately convertible (other than where the
                  same are issuable upon the exercise of Options) and the price
                  per share for which Common Stock is issuable upon such
                  exercise, conversion or exchange is less than the Set Price,
                  then the maximum total number of shares of Common Stock
                  issuable upon the exercise, conversion or exchange of all such
                  Convertible Securities will, as of the date of the issuance of
                  such Convertible Securities, be deemed to be outstanding and
                  to have been issued and sold by the Company for such price per
                  share. For the purposes of the preceding sentence, the "price
                  per share for which Common Stock is issuable upon such
                  exercise, conversion or exchange" is determined by dividing
                  (i) the total amount, if any, received or receivable by the
                  Company as consideration for the issuance or sale of all such
                  Convertible Securities, plus the minimum aggregate amount of
                  additional consideration, if any, payable to the Company upon
                  the exercise, conversion or exchange thereof at the time such
                  Convertible Securities first become exercisable, convertible
                  or exchangeable, by (ii) the maximum total number of shares of
                  Common Stock issuable upon the exercise, conversion or
                  exchange of all such Convertible Securities. No further
                  adjustment to the Exercise Price will be made upon the actual
                  issuance of such Common Stock upon exercise, conversion or
                  exchange of such Convertible Securities.

                        (C) Change in Option Price or Conversion Rate. If there
                  is a change at any time in (i) the amount of additional
                  consideration payable to the Company upon the exercise of any
                  Options; (ii) the amount of additional consideration, if any,
                  payable to the Company upon the exercise, conversion or
                  exchange of any Convertible Securities; or (iii) the rate at
                  which any Convertible Securities are convertible into or
                  exchangeable for Common Stock (in each such case, other than
                  under or by reason of provisions designed to protect against
                  dilution), the Exercise Price in effect at the time of such
                  change will be readjusted to the Exercise Price which would
                  have been in effect at such time had such Options or
                  Convertible Securities still outstanding provided for such
                  changed additional consideration or changed conversion rate,
                  as the case may be, at the time initially granted, issued or
                  sold.

                        (D) Treatment of Expired Options and Unexercised
                  Convertible Securities. If, in any case, the total number of
                  shares of Common Stock issuable upon exercise of any Option or
                  upon exercise, conversion or exchange of any Convertible
                  Securities is not, in fact, issued and the rights to exercise
                  such Option or to exercise, convert or exchange such
                  Convertible Securities shall have expired or terminated, the
                  Exercise Price then in effect will be readjusted to the
                  Exercise Price which would have been in effect at the time of
                  such expiration or termination had such Option or Convertible
                  Securities, to the extent outstanding immediately prior to
                  such expiration or termination (other than in respect of the
                  actual number of shares of Common Stock issued upon exercise
                  or conversion thereof), never been issued.

                        (E) Calculation of Consideration Received. If any Common
                  Stock, Options or Convertible Securities are issued, granted
                  or sold for cash, the consideration received therefor for
                  purposes of this Warrant will be the amount received by the
                  Company therefor, before deduction of reasonable commissions,
                  underwriting discounts or allowances or other reasonable
                  expenses paid or incurred by the Company in connection with
                  such issuance, grant or sale. In case any Common Stock,
                  Options or Convertible Securities are issued or sold for a
                  consideration part or all of which shall be other than cash,
                  the amount of the consideration other than cash received by
                  the Company will be the fair market value of such
                  consideration, except where such consideration consists of
                  securities, in which case the amount of consideration received
                  by the Company will be the Market Price thereof as of the date
                  of receipt. In case any Common Stock, Options or Convertible
                  Securities are issued in connection with any merger or
                  consolidation in which the Company is the surviving
                  corporation, the amount of consideration therefor will be
                  deemed to be the fair market value of such portion of the net
                  assets and business of the non-surviving corporation as is
                  attributable to such Common Stock, Options or Convertible
                  Securities, as the case may be. The fair market value of any
                  consideration other than cash or securities will be determined
                  in good faith by an investment banker or other appropriate
                  expert of national reputation selected by the Company and
                  reasonably acceptable to the holder hereof, with the costs of
                  such appraisal to be borne by the Company.

                        (F) Exceptions to Adjustment of Exercise Price. No
                  adjustment to the Exercise Price will be made (i) upon the
                  exercise of this Warrant or any other warrant of this series
                  or of any other series issued by the Company, or upon the
                  issuance, conversion, or redemption of, or payment of interest
                  under, any Convertible Securities issued pursuant to the
                  Purchase Agreement; (ii) upon the exercise or conversion of
                  any Convertible Securities, options or warrants issued and
                  outstanding on the initial issuance date of this Warrant;
                  (iii) upon the issuance of Common Stock or issuance, grant
                  exercise or conversion of any Convertible Securities which may
                  hereafter be issued, granted, exercised or converted (x) as
                  compensation to employees, consultants, brokers, investment
                  bankers or members of the Company's Board of Directors, or (y)
                  under any employee benefit plan of the Company now existing or
                  to be implemented in the future, so long as the issuance of
                  such Common Stock or Convertible Securities is approved by a
                  majority of the non-employee members of the Board of Directors
                  of the Company or a majority of the members of a committee of
                  non-employee directors established for such purpose; (iv) upon
                  the issuance of Common Stock or Convertible Securities in a
                  public offering, whether or not underwritten and upon the
                  exercise or conversion of such Convertible Securities; (v)
                  upon the issuance of Common Stock or Convertible Securities in
                  any transaction of the nature contemplated by Rule 145,
                  promulgated under the Securities Act; or (vi) in connection
                  with any strategic partnership or joint venture or acquisition
                  (the primary purpose of which is not to raise equity capital
                  for the Company) or (vii) the issuance of Common Stock or the
                  issuance, grant, exercise or conversion of Convertible
                  Securities issued to a bank or equipment lessor (pursuant to
                  transactions the primary purpose of which is not to raise
                  equity capital for the Company.

                  (iii) Notice of Adjustment. Upon the occurrence of any event
            which requires any adjustment of the Exercise Price, then, and in
            each such case, the Company shall give notice thereof to the holder
            of this Warrant, which notice shall state the Exercise Price
            resulting from such adjustment and the increase or decrease in the
            number of Warrant Shares purchasable at such price upon exercise,
            setting forth in reasonable detail the method of calculation and the
            facts upon which such calculation is based, provided that such
            notice shall not contain any material nonpublic information. Such
            calculation shall be certified by the chief financial officer of the
            Company.

                  (iv) Minimum Adjustment of Exercise Price. No adjustment of
            the Exercise Price shall be made in an amount of less than 1% of the
            Exercise Price in effect at the time such adjustment is otherwise
            required to be made, but any such lesser adjustment shall be carried
            forward and shall be made at the time and together with the next
            subsequent adjustment which, together with any adjustments so
            carried forward, shall amount to not less than 1% of such Exercise
            Price.

                  (v) Certain Events. If, at any time during the Exercise
            Period, any event occurs of the type contemplated by the adjustment
            provisions of this Section 11 but not expressly provided for by such
            provisions, the Company will give notice of such event as provided
            in Section 11 hereof, and the Company's Board of Directors will make
            an appropriate adjustment in the Exercise Price and the number of
            shares of Common Stock acquirable upon exercise of this Warrant so
            that the rights of the holder shall be neither enhanced nor
            diminished by such event.

                  (vi) Certain Definitions. "Common Stock Deemed Outstanding"
            shall mean the number of shares of Common Stock actually outstanding
            (not including shares of Common Stock held in the treasury of the
            Company), plus (x) in the case of any adjustment hereunder resulting
            from the issuance of any Options, the maximum total number of shares
            of Common Stock issuable upon the exercise of the Options for which
            the adjustment is required (including any Common Stock issuable upon
            the conversion of Convertible Securities issuable upon the exercise
            of such Options), and (y) in the case of any adjustment required
            hereunder resulting from the issuance of any Convertible Securities,
            the maximum total number of shares of Common Stock issuable upon the
            exercise, conversion or exchange of the Convertible Securities for
            which the adjustment is required, as of the date of issuance of such
            Convertible Securities, if any.

           12. Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then the Holder shall have the right thereafter to receive, at
their option, (a) upon exercise of this Warrant, the number of shares of Common
Stock of the successor or acquiring corporation or of the Company, if it is the
surviving corporation, and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of assets
by a Holder of the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to such event, or (b) cash equal to the value of
this Warrant as determined in accordance with the Black-Sholes option pricing
formula. In case of any such reorganization, reclassification, merger,
consolidation or disposition of assets, the successor or acquiring corporation
(if other than the Company) shall expressly assume the due and punctual
observance and performance of each and every covenant and condition of this
Warrant to be performed and observed by the Company and all the obligations and
liabilities hereunder, subject to such modifications as may be deemed
appropriate (as determined in good faith by resolution of the Board of Directors
of the Company) in order to provide for adjustments of Warrant Shares for which
this Warrant is exercisable which shall be as nearly equivalent as practicable
to the adjustments provided for in this Section 12. For purposes of this Section
12, "common stock of the successor or acquiring corporation" shall include stock
of such corporation of any class which is not preferred as to dividends or
assets over any other class of stock of such corporation and which is not
subject to redemption and shall also include any evidences of indebtedness,
shares of stock or other securities which are convertible into or exchangeable
for any such stock, either immediately or upon the arrival of a specified date
or the happening of a specified event and any warrants or other rights to
subscribe for or purchase any such stock. The foregoing provisions of this
Section 12 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

           13. Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

           14. Notice of Adjustment. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the Holder notice of such adjustment or adjustments setting forth the number
of Warrant Shares (and other securities or property) purchasable upon the
exercise of this Warrant and the Exercise Price of such Warrant Shares (and
other securities or property) after such adjustment, setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. Such notice, in the absence of
manifest error, shall be conclusive evidence of the correctness of such
adjustment.

           15. Notice of Corporate Action. If at any time:

              (a) the Company shall take a record of the holders of its Common
      Stock for the purpose of entitling them to receive a dividend or other
      distribution, or any right to subscribe for or purchase any evidences of
      its indebtedness, any shares of stock of any class or any other securities
      or property, or to receive any other right, or

              (b) there shall be any capital reorganization of the Company, any
      reclassification or recapitalization of the capital stock of the Company
      or any consolidation or merger of the Company with, or any sale, transfer
      or other disposition of all or substantially all the property, assets or
      business of the Company to, another corporation or,

              (c) there shall be a voluntary or involuntary dissolution,
      liquidation or winding up of the Company,

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their Warrant Shares for securities or other property
deliverable upon such disposition, dissolution, liquidation or winding up. Each
such written notice shall be sufficiently given if addressed to Holder at the
last address of Holder appearing on the books of the Company and delivered in
accordance with Section 17(d).

            16. Authorized Shares. The Company covenants that during the period
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares to provide for the issuance of the
Warrant Shares upon the exercise of any purchase rights under this Warrant. The
Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Principal Market
upon which the Common Stock may be listed.

            The Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate to protect the rights of Holder
against impairment. Without limiting the generality of the foregoing, the
Company will (a) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in
par value, (b) take all such action as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant, and (c) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof as may be necessary
to enable the Company to perform its obligations under this Warrant.

            Before taking any action which would result in an adjustment in the
number of Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall obtain all such authorizations or exemptions
thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

            17. Miscellaneous.

              (a) Jurisdiction. This Warrant shall constitute a contract under
      the laws of New York, without regard to its conflict of law, principles or
      rules.

              (b) Restrictions. The Holder acknowledges that the Warrant Shares
      acquired upon the exercise of this Warrant, if not registered, will have
      restrictions upon resale imposed by state and federal securities laws.

              (c) Nonwaiver and Expenses. No course of dealing or any delay or
      failure to exercise any right hereunder on the part of Holder shall
      operate as a waiver of such right or otherwise prejudice Holder's rights,
      powers or remedies, notwithstanding all rights hereunder terminate on the
      Termination Date. If the Company willfully and knowingly fails to comply
      with any provision of this Warrant, which results in any material damages
      to the Holder, the Company shall pay to Holder such amounts as shall be
      sufficient to cover any costs and expenses including, but not limited to,
      reasonable attorneys' fees, including those of appellate proceedings,
      incurred by Holder in collecting any amounts due pursuant hereto or in
      otherwise enforcing any of its rights, powers or remedies hereunder.

              (d) Notices. Any notice, request or other document required or
      permitted to be given or delivered to the Holder by the Company shall be
      delivered in accordance with the notice provisions of the Purchase
      Agreement.

              (e) Limitation of Liability. No provision hereof, in the absence
      of affirmative action by Holder to purchase Warrant Shares, and no
      enumeration herein of the rights or privileges of Holder, shall give rise
      to any liability of Holder for the purchase price of any Common Stock or
      as a stockholder of the Company, whether such liability is asserted by the
      Company or by creditors of the Company.

              (f) Remedies. Holder, in addition to being entitled to exercise
      all rights granted by law, including recovery of damages, will be entitled
      to specific performance of its rights under this Warrant. The Company
      agrees that monetary damages would not be adequate compensation for any
      loss incurred by reason of a breach by it of the provisions of this
      Warrant and hereby agrees to waive the defense in any action for specific
      performance that a remedy at law would be adequate.

               (g) Successors and Assigns. Subject to applicable securities
      laws, this Warrant and the rights and obligations evidenced hereby shall
      inure to the benefit of and be binding upon the successors of the Company
      and the successors and permitted assigns of Holder. The provisions of this
      Warrant are intended to be for the benefit of all Holders from time to
      time of this Warrant and shall be enforceable by any such Holder or holder
      of Warrant Shares.

              (h) Amendment. This Warrant may be modified or amended or the
      provisions hereof waived with the written consent of the Company and the
      Holder.

               (i) Severability. Wherever possible, each provision of this
      Warrant shall be interpreted in such manner as to be effective and valid
      under applicable law, but if any provision of this Warrant shall be
      prohibited by or invalid under applicable law, such provision shall be
      ineffective to the extent of such prohibition or invalidity, without
      invalidating the remainder of such provisions or the remaining provisions
      of this Warrant.

              (j) Headings. The headings used in this Warrant are for the
      convenience of reference only and shall not, for any purpose, be deemed a
      part of this Warrant.

Attention: Janis Paterson

Ladies and Gentlemen:

      Reference is made to the Convertible Subordinated Debentures and Warrants
Purchase Agreement and all exhibits thereto (the "Purchase Agreement"), dated as
of January ___, 2002, between the investors signatory thereto (the "Investors")
and FiberCore, Inc. (the "Company"). Pursuant to the Agreement, and subject to
the terms and conditions set forth in the Agreement, the Company has issued or
will issue to the Investors, in the aggregate, (i) $6,000,000 principal amount
of Convertible Subordinated Debentures with a mutual option to purchase up to an
additional $3,000,000 principal amount of Convertible Subordinated Debentures,
and (ii) Warrants to purchase shares of Common Stock (the "Warrants"). As a
condition to the effectiveness of the Purchase Agreement, the Company has agreed
to issue to you, as the transfer agent for the Company's Common Stock (the
"Transfer Agent"), these instructions relating to the Common Stock ("Common
Stock") to be issued to the Investors (or a permitted assignee) pursuant to the
Purchase Agreement upon conversion of the Convertible Subordinated Debentures or
upon exercise of the Warrants. All capitalized terms used herein and not
otherwise defined shall have the meaning set forth in the Purchase Agreement.

            1. ISSUANCE OF COMMON STOCK WITHOUT THE LEGEND

      Pursuant to the Purchase Agreement and the Registration Rights Agreement,
the Company is required to prepare and file with the SEC, and maintain the
effectiveness of, a registration statement or registration statements
registering the resale of the Common Stock to be acquired by the Investors (i)
upon exercise of the Warrants, and (ii) upon conversion of the Convertible
Subordinated Debentures, all as provided in the Registration Rights Agreement.
The Company will advise the Transfer Agent in writing of the effectiveness of
any such registration statement promptly upon its being declared effective, and
shall deliver an opinion of its counsel to that effect. The Transfer Agent shall
be entitled to rely on such advice and such opinion and shall assume that such
registration statement remains in effect unless the Transfer Agent is otherwise
advised in writing by the Company or such counsel, and the Transfer Agent shall
not be required to independently confirm the continued effectiveness of such
registration statement. In the circumstances set forth in the following three
paragraphs, the Transfer Agent shall deliver to the appropriate Investor
certificates representing Common Stock not bearing the Legend without requiring
further advice or instruction or additional documentation from the Company or
its counsel or the Investor or its counsel or any other party (other than as
described in such paragraphs).

            (a) At any time after the effective date of a registration statement
      (provided that the Company has not informed the Transfer Agent in writing
      that such registration statement is not effective) upon any surrender of
      one or more certificates evidencing Common Stock relating to such
      registration statement which bear the Legend, to the extent accompanied by
      a notice requesting the issuance of new certificates free of the Legend to
      replace those surrendered, in such names and in such denominations as the
      Investor may request, provided that in connection with any such event, the
      Investor (or its permitted assignee) shall confirm in writing to the
      Transfer Agent that (i) the Investor has sold, pledged or otherwise
      transferred or agreed to sell, pledge or otherwise transfer such Common
      Stock in a bona fide transaction to a third party that is not an affiliate
      of the Company in accordance with the plan of distribution set forth in
      the Registration Statement; and (ii) the Investor confirms to the transfer
      agent that the Investor has complied with the prospectus delivery
      requirement.

            (b) In the event a registration statement is not filed by the
      Company, or for any reason the registration statement which is filed by
      the Company is not declared effective by the SEC, the Investor, or its
      permitted assignee, or its broker confirms to the Transfer Agent that (i)
      the Investor has beneficially owned the shares of Common Stock for at
      least one year, (ii) counting the shares surrendered as being sold upon
      the date the unlegended Certificates would be delivered to the Investor
      (or the Trading Day immediately following if such date is not a Trading
      Day), the Investor will not have sold more than the greater of (a) one
      percent (1%) of the total number of outstanding shares of Common Stock or
      (b) the average weekly trading volume of the Common Stock for the
      preceding four weeks during the three months ending upon such delivery
      date (or the Trading Day immediately following if such date is not a
      Trading Day), and (iii) the Investor has complied with the manner of sale
      and notice requirements of Rule 144 under the Securities Act; or

            (c) The Investor (or its permitted assignee) shall represent that it
      is permitted to dispose of such shares of Common Stock without limitation
      as to amount or manner of sale pursuant to Rule 144(k) under the
      Securities Act.

      In the case of subparagraphs (b) or (c), the Transfer Agent shall be
entitled to require an opinion of counsel to the Company or from counsel to the
Investor (which opinion shall be from an attorney or law firm reasonably
acceptable to the Transfer Agent and be in form and substance reasonably
acceptable to the Transfer Agent). Any advice, notice, or instructions to the
Transfer Agent required or permitted to be given hereunder may be transmitted
via facsimile to the Transfer Agent's facsimile number of (801) 281-9750.

            2.  MECHANICS OF DELIVERY OF CERTIFICATES REPRESENTING
                COMMON STOCK

      In connection with any conversion of the Convertible Subordinated
Debentures or exercise of Warrants pursuant to which the Investor acquires
Common Stock under the Agreement, the Transfer Agent is hereby instructed to
deliver to the Investor, certificates representing Common Stock (with or without
the Legend, as appropriate) within three (3) Trading Days of receipt by the
Transfer Agent of a copy of the Notice of Conversion (in the case of the
Convertible Subordinated Debenture) or Notice of Exercise (in the case of the
Warrant) from the Investor, and to deliver such certificates to the Investor, in
the case of original issuance, and in the case of subsequent transfer, if the
Transfer Agent is able to deliver such Common Stock to the Investor's account
pursuant to the DWAC system of the Depository Trust Company, the Transfer Agent
shall make delivery pursuant to such system and provide the Investor with
confirmation thereof in lieu of such Common Stock certificates.

            3.  FEES OF TRANSFER AGENT; INDEMNIFICATION

      The Company agrees to pay the Transfer Agent for all fees incurred in
connection with these Irrevocable Instructions. The Company agrees to indemnify
the Transfer Agent and its officers, employees and agents, against any losses,
claims, damages or liabilities, joint or several, to which it or they become
subject based upon the performance by the Transfer Agent of its duties in
accordance with the Irrevocable Instructions, other than as a result of the
Transfer Agent's gross negligence or willful misconduct.

            4.  THIRD PARTY BENEFICIARY

      The Company and the Transfer Agent acknowledge and agree that the
Investors are each an express third party beneficiary of these Irrevocable
Instructions and shall be entitled to rely upon, and enforce, the provisions
thereof.

EXHIBIT 10.1

                            OPNET TECHNOLOGIES, INC.

                 Amended and Restated 2000 Stock Incentive Plan
                 ----------------------------------------------

1.   Purpose
     -------

The purpose of this Amended and Restated 2000 Stock Incentive Plan (the "Plan")
of OPNET Technologies, Inc., a Delaware corporation (the "Company"), is to
advance the interests of the Company's stockholders by enhancing the Company's
ability to attract, retain and motivate persons who make (or are expected to
make) important contributions to the Company by providing such persons with
equity ownership opportunities and performance-based incentives and thereby
better aligning the interests of such persons with those of the Company's
stockholders. Except where the context otherwise requires, the term "Company"
shall include any of the Company's present or future subsidiary corporations as
defined in Section 424(f) of the Internal Revenue Code of 1986, as amended, and
any regulations promulgated thereunder (the "Code").

2.   Eligibility
     -----------

All of the Company's employees, officers, directors, consultants and advisors
(and any individuals who have accepted an offer for employment) are eligible to
be granted options, restricted stock awards, or other stock-based awards (each,
an "Award") under the Plan. Each person who has been granted an Award under the
Plan shall be deemed a "Participant."

3.   Administration, Delegation
     --------------------------

     (a)  Administration by Board of Directors. The Plan will be administered
          ------------------------------------
by the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Awards and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable.
The Board may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final
judge of such expediency. All decisions by the Board shall be made in the
Board's sole discretion and shall be final and binding on all persons having or
claiming any interest in the Plan or in any Award. No director or person acting
pursuant to the authority delegated by the Board shall be liable for any action
or determination relating to or under the Plan made in good faith.

     (b)  Appointment of Committees. To the extent permitted by applicable
          -------------------------
law, the Board may delegate any or all of its powers under the Plan to one or
more committees or subcommittees of the Board (a "Committee"). All references in
the Plan to the "Board" shall mean the Board or a Committee of the Board to the
extent that the Board's powers or authority under the Plan have been delegated
to such Committee.

4.   Stock Available for Awards
     --------------------------

     (a)  Number of Shares. Subject to adjustment under Section 8, Awards may
          ----------------
be made under the Plan for up to 3,792,061 shares of common stock, par value
$0.001 per share, of the Company (the "Common Stock").

     (b)  The number of shares of Common Stock available for issuance under
the Plan shall automatically increase on the first trading day of each calendar
year, beginning with the 2002 calendar year and continuing through the term of
this Plan, by an amount equal to three percent (3%) of the shares of Common
Stock outstanding on the last trading day of the preceding calendar year;
provided, however, that in no event shall any such annual increase exceed
--------  -------
1,500,000 shares.

     (c)  If any Award expires or is terminated, surrendered or canceled
without having been fully exercised or is forfeited in whole or in part or
results in any Common Stock not being issued, the unused Common Stock covered by
such Award shall again be available for the grant of Awards under the Plan,
subject, however, in the case of Incentive Stock Options (as hereinafter
defined), to any limitation required under the Code. Shares issued under the
Plan may consist in whole or in part of authorized but unissued shares or
treasury shares.

     (d)  Per-Participant Limit.  Subject to adjustment under Section 8,
          ---------------------
the maximum number of shares of Common Stock with respect to which Awards may
be granted to any Participant under the Plan shall be 300,000 per calendar year.
The per-Participant limit described in this Section 4(d) shall be construed and
applied consistently with Section 162(m) of the Code ("Section 162(m)").

5.   Stock Options
     -------------

     (a) General. The Board may grant options to purchase Common Stock

(each, an "Option") and determine the number of shares of Common Stock to be
covered by each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option."

     (b)  Incentive Stock Options. An Option that the Board intends to be an
          -----------------------
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

     (c)  Exercise Price. The Board shall establish the exercise price at the
          --------------
time each Option is granted and specify it in the applicable option agreement;

determined by the Board, at the time the Incentive Stock Option is granted.

     (d)  Duration of Options. Each Option shall be exercisable at such times
          -------------------
and subject to such terms and conditions as the Board may specify in the
applicable option agreement; provided, however, that no Option will be granted
                             --------  -------
for a term in excess of 10 years.

     (e)  Exercise of Option. Options may be exercised by delivery to the
          ------------------
Company of a written notice of exercise signed by the proper person or by any
other form of notice (including electronic notice) approved by the Board
together with payment in full as specified in Section 5(f) for the number of
shares for which the Option is exercised.

     (f)  Payment Upon Exercise.  Common Stock purchased upon the exercise
          ---------------------
of an Option granted under the Plan shall be paid for as follows:

          (1) in cash or by check, payable to the order of the Company;

          (2) except as the Board may, in its sole discretion, otherwise
              provide in an option agreement, by (i) delivery of an
              irrevocable and unconditional undertaking by a creditworthy
              broker to deliver promptly to the Company sufficient funds to
              pay the exercise price or (ii) delivery by the Participant to
              the Company of a copy of irrevocable and unconditional
              instructions to a creditworthy broker to deliver promptly to
              the Company cash or a check sufficient to pay the exercise price;

          (3) by delivery of shares of Common Stock owned by the Participant
              valued at their fair market value as determined by (or in a
              manner approved by) the Board in good faith ("Fair Market Value"),
              provided (i) such method of payment is then permitted under
              applicable law and (ii) such Common Stock was owned by the
              Participant at least six months prior to such delivery;

          (4) payment of such other lawful consideration as the Board may
              determine; or

          (5) by any combination of the above permitted forms of payment.

6.   Restricted Stock
     ----------------

     (a)  Grants. The Board may grant Awards entitling recipients to acquire
          ------
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, a "Restricted Stock Award").

     (b)  Terms and Conditions. The Board shall determine the terms and
          --------------------
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any. Any stock certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or if the Participant has died, to the
beneficiary designated, in a manner determined by the Board, by a Participant to
receive amounts due or exercise rights of the Participant in the event of the
Participant's death (the "Designated Beneficiary"). In the absence of an
effective designation by a Participant, Designated Beneficiary shall mean the
Participant's estate.

7.   Other Stock-Based Awards
     ------------------------

The Board shall have the right to grant other Awards based upon the Common Stock
having such terms and conditions as the Board may determine, including the grant
of shares based upon certain conditions, the grant of securities convertible
into Common Stock and the grant of stock appreciation rights.

8.   Adjustments for Changes in Common Stock and Certain Other Events
     ----------------------------------------------------------------

     (a)  Changes in Capitalization. In the event of any stock split, reverse
          -------------------------

reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock, other than a normal
cash dividend, (i) the number and class of securities available under this Plan,
(ii) the per-Participant limit set forth in Section 4(d), (iii) the number and
class of securities and exercise price per share subject to each outstanding
Option, (iv) the repurchase price per share subject to each outstanding

                                       2

<PAGE>

Restricted Stock Award and (v) the terms of each other outstanding Award shall
be appropriately adjusted by the Company (or substituted Awards may be made, if
applicable) to the extent the Board shall determine, in good faith, that such an
adjustment (or substitution) is necessary and appropriate. If this Section 8(a)
applies and Section 8(c) also applies to any event, Section 8(c) shall be
applicable to such event, and this Section 8(a) shall not be applicable.

     (b)  Liquidation or Dissolution.  In the event of a proposed
          --------------------------
liquidation or dissolution of the Company, the Board shall upon written notice
to the Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

     (c)  Acquisition and Change in Control Events
          ----------------------------------------

                    (i)   any merger or consolidation of the Company with or
                          into another entity as a result of which the Common
                          Stock is converted into or exchanged for the right to
                          receive cash, securities or other property; or

                          immediately following such Business Combination, each
                          of the following two conditions is satisfied: (x) all
                          or substantially all of the individuals and entities
                          who were the beneficial owners of the Outstanding
                          Company Common Stock and Outstanding Company Voting
                          Securities immediately prior to such Business
                          Combination beneficially own, directly or indirectly,
                          more than 50% of the then-outstanding shares of common
                          stock and the combined voting power of the then-
                          outstanding securities entitled to vote generally in
                          the election of directors, respectively, of the
                          resulting or acquiring corporation in such Business
                          Combination (which shall include, without
                          limitation, a corporation which as a result of such
                          transaction owns the Company or substantially all of
                          the Company's assets either directly or through one
                          or more subsidiaries) (such resulting or acquiring

                          Corporation") in substantially the same proportions
                          as their ownership of the Outstanding Company Common
                          Stock and Outstanding Company Voting Securities,
                          respectively, immediately prior to such Business

                          Persons, the Acquiring Corporation or any employee
                          benefit plan (or related trust) maintained or
                          sponsored by the Company or by the Acquiring
                          Corporation) beneficially owns, directly or
                          indirectly, 30% or more of the then-outstanding
                          shares of common stock of the Acquiring Corporation,
                          or of the combined voting power of the then-
                          outstanding securities of such corporation entitled
                          to vote generally in the election of directors
                          (except to the extent that such ownership existed
                          prior to the Business Combination).

               (c)  "Good Reason" shall mean any significant diminution in the
                    Participant's title, authority, or responsibilities from and
                    after such Acquisition Event or Change in Control Event, as
                    the case may be, or any reduction in the annual cash
                    compensation payable to the Participant from and after
                    such Acquisition Event or Change in Control Event, as the
                    case may be, or the relocation of the place of business at
                    which the Participant is principally located to a location
                    that is greater than 50 miles from the current site.

               (d)  "Cause" shall mean any (i) willful failure by the
                    Participant, which failure is not cured within 30 days of
                    written notice to the Participant from the Company, to
                    perform his or her material responsibilities to the Company
                    or (ii) willful misconduct by the Participant which affects
                    the business reputation of the Company. The Participant
                    shall be considered to have been discharged for "Cause" if
                    the Company determines, within 30 days after the
                    Participant's resignation, that discharge for Cause was
                    warranted.

          (2)  Effect on Options
               -----------------

               (a)  Acquisition Event.  Upon the occurrence of an Acquisition
                    -----------------
                    Event (regardless of whether such event also constitutes a
                    Change in Control Event), or the execution by the Company of
                    any agreement with respect to an Acquisition Event
                    (regardless of whether such event will result in a Change in
                    Control Event), the Board shall provide that all outstanding
                    Options shall be assumed, or equivalent options shall be
                    substituted for, by the acquiring or succeeding corporation
                    (or an affiliate thereof); provided that if such Acquisition
                                               -------------
                    Event also constitutes a Change in Control  Event, except
                    to the extent specifically provided to the contrary in the
                    instrument evidencing any Option or any other agreement
                    between a Participant and the Company, such assumed or
                    substituted options shall become immediately exercisable in
                    full if, on or prior to the first anniversary of the date of
                    the consummation of the Acquisition Event, the Participant's
                    employment with the Company

                                       4

                    or the acquiring or succeeding corporation is terminated for
                    Good Reason by the Participant or is terminated without
                    Cause by the Company or the acquiring or succeeding
                    corporation. For purposes hereof, an Option shall be
                    considered to be assumed if, following consummation of the
                    Acquisition Event, the Option confers the right to purchase,
                    for each share of Common Stock subject to the Option
                    immediately prior to the consummation of the Acquisition
                    Event, the consideration (whether cash, securities or other
                    property) received as a result of the Acquisition Event by
                    holders of Common Stock for each share of Common Stock held
                    immediately prior to the consummation of the Acquisition
                    Event (and if holders were offered a choice of
                    consideration, the type of consideration chosen by the
                    holders of a majority of the outstanding shares of Common
                    Stock); provided, however, that if the consideration
                    received as a result of the Acquisition Event is not solely
                    common stock of the acquiring or succeeding corporation (or
                    an affiliate thereof), the Company may, with the consent of
                    the acquiring or succeeding corporation, provide for the
                    consideration to be received upon the exercise of Options to
                    consist solely of common stock of the acquiring or
                    succeeding corporation (or an affiliate thereof) equivalent
                    in fair market value to the per share consideration received
                    by holders of outstanding shares of Common Stock as a result
                    of the Acquisition Event.

                    Notwithstanding the foregoing, if the acquiring or
                    succeeding corporation (or an affiliate thereof) does not
                    agree to assume, or substitute for, such Options, then the
                    Board shall, upon written notice to the Participants,
                    provide that all then unexercised Options will become
                    exercisable in full as of a specified time prior to the
                    Acquisition Event and will terminate immediately prior to
                    the consummation of such Acquisition Event, except to the
                    extent exercised by the Participants before the consummation
                    of such Acquisition Event; provided, however, that in the
                    event of an Acquisition Event under the terms of which
                    holders of Common Stock will receive upon consummation
                    thereof a cash payment for each share of Common Stock
                    surrendered pursuant to such Acquisition Event (the
                    "Acquisition Price"), then the Board may instead provide
                    that all outstanding Options shall terminate upon
                    consummation of such Acquisition Event and that each
                    Participant shall receive, in exchange therefore, a cash
                    payment equal to the amount (if any) by which (A) the
                    Acquisition Price multiplied by the number of shares of
                    Common Stock subject to such outstanding Options (whether or
                    not then exercisable) exceeds (B) the aggregate exercise
                    price of such Options.

               (b)  Change in Control Event that is not an Acquisition Event.
                    --------------------------------------------------------
                    Following the occurrence of a Change in Control Event that
                    does not also constitute an Acquisition Event, except to the
                    extent specifically provided to the contrary in the
                    instrument evidencing any Option or any other agreement
                    between a Participant and the Company, each such Option
                    shall be immediately exercisable in full if, on or prior to
                    the first anniversary of the date of the consummation of the
                    Change in Control Event, the Participant's employment with
                    the Company or the acquiring or succeeding corporation is
                    terminated for Good Reason by the Participant or is
                    terminated without Cause by the Company or the acquiring or
                    succeeding corporation.

          (3)  Effect on Restricted Stock Awards
               ---------------------------------

               (a)  Acquisition Event that is not a Change in Control Event.
                    Upon the occurrence of an Acquisition Event that is not a
                    Change in Control Event, the repurchase and other rights of
                    the Company under each outstanding Restricted Stock Award
                    shall inure to the benefit of the Company's successor and
                    shall apply to the cash, securities or other property which
                    the Common Stock was converted into or exchanged for
                    pursuant to such Acquisition Event in the same manner and to
                    the same extent as they applied to the Common Stock subject
                    to such Restricted Stock Award.

               (b)  Change in Control Event.  Following the occurrence of a
                    -----------------------
                    Change in Control Event (regardless of whether such event
                    also constitutes an Acquisition Event), except to the extent
                    specifically provided to the contrary in the instrument
                    evidencing any Restricted Stock Award or any other agreement
                    between a Participant and the Company, each such Restricted
                    Stock Award shall immediately become free from all
                    conditions or restrictions if, on or prior to the first
                    anniversary of the date of the consummation of the Change in

                                       5

<PAGE>

                    Control Event, the Participant's employment with the Company
                    or the acquiring or succeeding corporation is terminated for
                    Good Reason by the Participant or is terminated without
                    Cause by the Company or the acquiring or succeeding
                    corporation.

          (4)  Effect on Other Awards

               (a)  Acquisition Event that is not a Change in Control Event.
                    -------------------------------------------------------
                    The Board shall specify the effect of an Acquisition Event
                    that is not a Change in Control Event on any other Award
                    granted under the Plan at the time of the grant of such
                    Award.

               (b)  Change in Control Event.  Following the occurrence of a
                    -----------------------
                    Change in Control Event (regardless of whether such event
                    also constitutes an Acquisition Event), except to the extent
                    specifically provided to the contrary in the instrument
                    evidencing any Award or any other agreement between a
                    Participant and the Company, each such Award shall
                    immediately become fully exercisable, realizable, vested or
                    free from conditions or restrictions if, on or prior to the
                    first anniversary of the date of the consummation of the
                    Change in Control Event, the Participant's employment with
                    the Company or the acquiring or succeeding corporation is
                    terminated for Good Reason by the Participant or is
                    terminated without Cause by the Company or the acquiring or
                    succeeding corporation.

          (5)  Limitations. Notwithstanding the foregoing provisions of this
               -----------
               Section 8(c), if the Change in Control Event is intended to
               be accounted for as a "pooling of interests" for financial
               accounting purposes, and if the acceleration to be effected
               by the foregoing provisions of this Section 8(c) would
               preclude accounting for the Change in Control Event as a
               "pooling of interests" for financial accounting purposes,
               then no such acceleration shall occur upon the Change in
               Control Event.

9.   General Provisions Applicable to Awards
     ---------------------------------------

     (a)  Transferability of Awards. Except as the Board may otherwise
determine or provide in an Award, Awards shall not be sold, assigned,
transferred, pledged or otherwise encumbered by the person to whom they are
granted, either voluntarily or by operation of law, except by will or the laws
of descent and distribution, and, during the life of the Participant, shall be
exercisable only by the Participant. References to a Participant, to the extent
relevant in the context, shall include references to authorized transferees.

     (b)  Documentation. Each Award shall be evidenced by a written
instrument in such form as the Board shall determine. Each Award may contain
terms and conditions in addition to those set forth in the Plan.

     (c)  Board Discretion.  Except as otherwise provided by the Plan, each
          ----------------
Award may be made alone or in addition to or in relation to any other Award.
The terms of each Award need not be identical, and the Board need not treat
Participants uniformly.

     (d)  Termination of Status. The Board shall determine the effect on an
          ---------------------
Award of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

     (e)  Withholding. Each Participant shall pay to the Company, or make
          -----------
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, Participants may, to the extent then permitted under
applicable law, satisfy such tax obligations in whole or in part by delivery of
shares of Common Stock, including shares retained from the Award creating the
tax obligation, valued at their Fair Market Value. The Company may, to the
extent permitted by law, deduct any such tax obligations from any payment of any
kind otherwise due to a Participant.

     (f)  Amendment of Award. The Board may amend, modify or terminate any
          ------------------
outstanding Award, including but not limited to, substituting therefore another
Award of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

     (g)  Conditions on Delivery of Stock. The Company will not be obligated
          -------------------------------
to deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed

                                       6

<PAGE>

and delivered to the Company such representations or agreements as the Company
may consider appropriate to satisfy the requirements of any applicable laws,
rules or regulations.

     (h)  Acceleration. The Board may at any time provide that any Options
          ------------
shall become immediately exercisable in full or in part, that any Restricted
Stock Awards shall be free of restrictions in full or in part or that any other
Awards may become exercisable in full or in part or free of some or all
restrictions or conditions, or otherwise realizable in full or in part, as the
case may be.

10.  Miscellaneous
     -------------

     (a)  No Right to Employment or Other Status. No person shall have any
          --------------------------------------
claim or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

     (b)  No Rights as Stockholder. Subject to the provisions of the
          ------------------------
applicable Award, no Participant or Designated Beneficiary shall have any rights
as a stockholder with respect to any shares of Common Stock to be distributed
with respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

     (c)  Effective Date and Term of Plan. The Plan shall become effective on
          -------------------------------
the date on which it is adopted by the Board, but no Award granted to a
Participant that is intended to comply with Section 162(m) shall become
exercisable, vested or realizable, as applicable to such Award, unless and until
the Plan has been approved by the Company's stockholders to the extent
stockholder approval is required by Section 162(m) in the manner required under
Section 162(m) (including the vote required under Section 162(m)). No Awards
shall be granted under the Plan after the completion of ten years from the
earlier of (i) the date on which the Plan was adopted by the Board or (ii) the
date the Plan was approved by the Company's stockholders, but Awards previously
granted may extend beyond that date.

     (d)  Amendment of Plan. The Board may amend, suspend or terminate the
          -----------------
Plan or any portion thereof at any time, provided that to the extent required by
Section 162(m), no Award granted to a Participant that is intended to comply
with Section 162(m) after the date of such amendment shall become exercisable,
realizable or vested, as applicable to such Award, unless and until such
amendment shall have been approved by the Company's stockholders if required by
Section 162(m) (including the vote required under Section 162(m)).

     (e)  Governing Law. The provisions of the Plan and all Awards made
          -------------
hereunder shall be governed by and interpreted in accordance with the laws of
the State of Delaware, without regard to any applicable conflicts of law.
