Spencer Trask Specialty Group, LLC

Dear Sirs:

        As you know, Vyteris Holdings (Nevada), Inc. (the "Company") has been
offered a term sheet by Satellite Asset Management, LP, dated July 28, 2005 (the
"Term Sheet'), pursuant to which the Company expects to offer $10,000,000 of
convertible debentures and warrants. The Term Sheet contemplates, among other
things, that as a condition of the transactions described therein, Spencer Trask
Specialty Group, an affiliate of Spencer Trask Ventures, will be required to
guarantee the principal and interest payments on such debentures if the Company
does not consummate a so-called "qualified equity offering". A qualified equity
offering is defined as one or more offerings of equity securities that raise
total gross proceeds of $15,000,000 or more within a specified six month period.

        The Company has concluded that it is in its best interests to proceed
with the transactions contemplated by the Term Sheet as soon as possible.
Spencer Trask Specialty Group, in turn, has conditioned its willingness to
provide the above-mentioned guarantees on the Company's willingness to provide
the assurance described herein. To induce Spencer Trask Specialty Group to
provide the guarantee contemplated by the Term Sheet, the Company hereby agrees
to use reasonable commercial efforts to effect a "qualified equity offering" (as
defined in the Term Sheet) within the six month period specified in the Term
Sheet.

        This letter supercedes the prior letter.

                                             Very truly yours,

                                             VYTERIS HOLDINGS (NEVADA), INC.

Spencer Trask Ventures, Inc.

New York, New York 10022

Dear Sirs:

        As you know, Vyteris Holdings (Nevada), Inc. (the "Company") has been
offered a term sheet by Satellite Asset Management, LP, dated July 28, 2005 (the
"Term Sheet'), pursuant to which the Company expects to offer $10,000,000 of
convertible debentures and warrants.

        The Company or its subsidiary has previously entered into agreements
(the "Agreements") providing Spencer Trask Ventures with a right of first
refusal in connection with private placements of securities. While this right
has been waived by Spencer Trask Ventures in connection with the offering of
debentures and warrants pursuant to the Term Sheet, it has not been waived in
connection with any "qualified equity offering" provided for in the Term Sheet.

        The Company has concluded that it is in its best interests to proceed
with the transactions contemplated by the Term Sheet as soon as possible. In
light of the Agreements, and in consideration for the latter assisting the
Company in effectuating the transactions described in the Term Sheet, the
Company hereby agrees as follows:

        At the present time, the Company is unable to determine whether a
Qualified Equity Offering (as defined in the Term Sheet) will be effected as a
private placement or as a public offering. Inasmuch as the Company is already
obligated (pursuant to the Agreements) to provide Spencer Trask Ventures with a
right of first refusal in connection with any private placement that is part of
a Qualified Equity Offering, the Company hereby agrees to provide Spencer Trask
Ventures with comparable right of first refusal protection in the event that the
Qualified Equity Offering is structured as a public offering. According, the
Company hereby grants Spencer Trask Ventures the irrevocable preferential right
of first refusal described below to act as agent (or as a co-agent with another
placement agent identified by Spencer Trask Ventures, subject to the Company's
approval, which approval shall not be unreasonably withheld) for the Qualified
Equity Offering to the extent that the

<PAGE>

Qualified Equity Offering is structured as a private offering and to act as the
lead underwriter (or as a co-lead underwriter with another underwriter
identified by Spencer Trask Ventures, subject to the Company's approval, which
approval shall not be unreasonably withheld) on a best efforts basis to the
extent that the Qualified Equity Offering is structured as a public offering.
The Company agrees to offer Spencer Trask Ventures the opportunity to sell such
securities in a Qualified Equity Offering on terms no less favorable than it can
obtain elsewhere. If within 20 business days of the receipt of notice of
intention to effect a Qualified Equity Offering and statement of terms Spencer
Trask Ventures does not accept in writing such offer to act as agent or lead
underwriter with respect to such offering upon the terms proposed, the Company
shall be free to negotiate terms with third parties with respect to such
offering and to effect such offering on such proposed terms. Before the Company
shall accept any proposal materially less favorable to it than as originally
proposed to Spencer Trask Ventures, Spencer Trask Ventures' preferential rights
shall be applied, and the procedure set forth above with respect to such
modified proposal adopted. If a proposed financing is not consummated under the
conditions set forth above, the right of first refusal described herein shall be
reinstated upon the same terms and conditions as aforesaid.

        This letter supercedes the prior letter.

                                                              Very truly yours,

        Re:     $1 MILLION FINANCING

Gentlemen:

        Reference is made to that certain proposed term sheet between Vyteris
Holdings (Nevada), Inc. (the "Company") and Satellite Asset Management, L.P. or
such other parties as may be the case ("SAM") of even date herewith, as same may
be subsequently amended or supplemented (the "Term Sheet"), a copy of which is
attached hereto and made a part hereof.

        This letter agreement shall confirm the understandings and agreements
between the Company and Qubit Holdings, LLC ("Qubit") as follows:

        1. Simultaneous with the execution and delivery of this letter agreement
by the parties hereto, Qubit is wire-transferring the sum of the One Million
($1,000,000) Dollars to an account designated by the Company (the "Qubit

        2. In the event that the transactions contemplated by the Term Sheet are
consummated, the Qubit Payment shall be deemed to be part of such transactions.
By way of example, if a $10 million of investment are made pursuant to the Term
Sheet, the Qubit Payment shall be deemed to be $1 million of such $10 million
investment.

        3. In the event that the transactions contemplated by the Term Sheet are
not consummated, the Qubit Payment shall nevertheless be deemed to be a $1
million investment in accordance with the terms and conditions of the Term
Sheet.

        4. Anything contained in the Term Sheet to the contrary notwithstanding,
this letter agreement is, and shall be considered to be, a binding agreement of
the Company. This letter agreement has been approved by the majority of the
disinterested members of the Board of Directors of the Company.

Investor is a party will constitute, such Investor's valid and legally binding
obligation, enforceable in accordance with its terms, subject to (i) applicable
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other
similar laws of general application relating to or affecting the enforcement of

decision with respect to its investment in the Securities.

such Investor with information regarding the business, operations and financial
condition of the Company and has, prior to the Execution Date, granted to such

concerning the Company and materials relating to the terms and conditions of the
purchase and sale of the Debentures and Warrants hereunder, in order for such
Investor to make an informed decision with respect to its investment in the

             registered under the Securities Act of 1933, as amended (the
             "Securities Act"), or the securities laws of any state, and
             may not be offered or sold unless a registration statement
             under the Securities Act and applicable state securities laws
             shall have become effective with regard thereto, or the
             Corporation has been furnished with an opinion of legal
             counsel, reasonably satisfactory to the Corporation, to the
             effect that an exemption from registration under the
             Securities Act and applicable state securities laws is
             available in connection with such offer or sale.
             Notwithstanding the foregoing but subject to compliance with

             secured by such securities and (ii) may be transferred or
             assigned to an affiliate of the holder hereof."

             Notwithstanding the foregoing, it is agreed that, as long as

registration statement, (B) have been sold pursuant to Rule 144, subject to
receipt by the Company of customary documentation reasonably acceptable to the
Company in connection therewith, or (C) are eligible for resale under Rule
144(k) or any successor provision, such Securities shall be issued without any
legend or other restrictive language and, with respect to Securities upon which
such legend is stamped, the Company shall issue new certificates without such
legend to the holder upon request.

         2.6 Reliance on Exemptions. Such Investor understands that the
Securities are being offered and sold to it in reliance upon specific exemptions
from the registration requirements of United States federal and state securities

its behalf or at its discretion has established or maintained a short position
in the Company's securities at any time since the earlier to occur of (a) the
thirty (30) days immediately preceding the Execution Date and (b) the time such
Investor was first informed by the Company or any placement agent acting on

as of the date hereof and as of each Closing Date, there has been no material
adverse change to the business, operations, properties, financial condition, or
results of operations of the Company and the Subsidiaries taken as a whole since
the date of the Company's most recent audited financial statements contained in
the Disclosure Documents.

             3.8.2 The Company and each of the Subsidiaries has prepared in good
faith and duly and timely filed all tax returns required to be filed by it and
such returns are complete and accurate in all material respects and the Company
and each of the Subsidiaries has paid all taxes required to have been paid by
it, except for taxes which it reasonably disputes in good faith or the failure
of which to pay has not had or would not reasonably be expected to have a
Material Adverse Effect. Neither the Company nor any Subsidiary has any material
liability with respect to taxes that accrued on or before the date of the most
recent balance sheet of the Company included in the Disclosure Documents in
excess of the amounts accrued with respect thereto that are reflected on such
balance sheet.

             3.8.3 Neither the Company nor any of the Subsidiaries is the
subject of any pending or, to the Company's knowledge, threatened inquiry,
investigation or administrative or legal proceeding by the Internal Revenue
Service, the taxing authorities of any state or local jurisdiction, the
Commission, the NASD, any state securities commission or other Governmental
Authority.

             3.8.4 Except as described on Schedule 3.8 hereto, there is no
material claim, litigation or administrative proceeding pending, or, to the
Company's knowledge, threatened or contemplated, against the Company or any of
the Subsidiaries, or against any officer, director or employee of the Company or
any such Subsidiary in connection with such person's employment therewith.
Neither the Company nor any of the Subsidiaries is a party to or subject to the
provisions of, any order, writ, injunction, judgment or decree of any court or
Government Authority which has had or would reasonably be expected to have a
Material Adverse Effect.

         3.9 Form SB-2. The Company is eligible to register the Conversion
Shares and Warrant Shares for resale in a secondary offering by each Investor on
a registration statement on Form SB-2 under the Securities Act. To the Company's
knowledge, as of the date hereof and as of each Closing Date, there exist no
facts or circumstances (including without limitation any required approvals or
waivers of any circumstances that may delay or prevent the obtaining of
accountant's consents) that could reasonably be expected to prohibit or delay
the preparation, filing or effectiveness of such registration statement.

         3.10 Acknowledgement of Dilution. The Company acknowledges that the
issuance of the Conversion Shares upon conversion of the Debentures and the
issuance of the Warrant Shares upon exercise of the Warrants may result in
dilution of the outstanding shares of Common Stock, which dilution may be
substantial under certain market conditions. The Company further acknowledges
that its obligation to issue Conversion Shares upon conversion of the Debentures
in accordance with the terms of the Debentures, and to issue Warrant Shares upon
exercise of the Warrants in accordance with the terms of the Warrants, is
unconditional (other than with respect to the conditions set forth in the
Debentures and the Warrants, respectively) regardless of the effect of any such
dilution.

         3.11 Intellectual Property. Except as set forth in Schedule 3.11:

                                       16
<PAGE>

             (a) The Company and the Subsidiaries own, free and clear of claims
or rights or any other Person, with full right to use, sell, license,
sublicense, dispose of, and bring actions for infringement of, or, to the
knowledge of the Company, has acquired licenses or other rights to use, all
Intellectual Property necessary for the conduct of its respective business as
presently conducted in all material respects (other than with respect to
software which is generally commercially available and not used or incorporated
into the Company's products and open source software which may be subject to one
or more "open source" licenses), except as has not had and would not reasonably
be expected to have a Material Adverse Effect.

             (b) Neither the Company nor any of the Subsidiaries has received
written notice from any third party asserting that any Intellectual Property
owned or licensed by the Company or the Subsidiaries, or which the Company or
any of the Subsidiaries otherwise has the right to use, is invalid or
unenforceable by the Company or such Subsidiary and, to the Company's knowledge,
there is no valid basis for any such claim (whether or not pending or
threatened), except as has not had and would not reasonably be expected to have
a Material Adverse Effect.

             (c) The business of the Company and the Subsidiaries as presently
conducted and the production, marketing, licensing, use and servicing of any
products or services of the Company and the Subsidiaries do not, to the
knowledge of the Company, infringe any patent, trademark, copyright, or trade
secret rights of any third parties or any other Intellectual Property of any
third parties, except, in each such case, as has not had and would not
reasonably be expected to have a Material Adverse Effect.

             (d) No claim is pending or, to the Company's knowledge, threatened
against the Company or any of the Subsidiaries nor has the Company or any of the
Subsidiaries received any written notice or other written claim from any Person
asserting that any of the Company's or the Subsidiaries' present or contemplated
activities infringe or may infringe any Intellectual Property of such Person,
and the Company is not aware of any infringement by any other Person of any
rights of the Company or any of the Subsidiaries under any Intellectual Property
Rights, except as has not had and would not reasonably be expected to have a
Material Adverse Effect.

             (e) All licenses or other agreements under which the Company or any
of the Subsidiaries is granted Intellectual Property (excluding licenses to use
software utilized in the Company's or such Subsidiary's internal operations and
which is generally commercially available) are in full force and effect and, to
the Company's knowledge, there is no default by any party thereto, except as has
not had and would not reasonably be expected to have a Material Adverse Effect.
The Company has no reason to believe that the licensors under such licenses and
other agreements do not have and did not have all requisite power and authority
to grant the rights to the Intellectual Property purported to be granted
thereby, except as has not had and would not reasonably be expected to have a
Material Adverse Effect.

             (f) All licenses or other agreements under which the Company or any
of the Subsidiaries has granted rights to Intellectual Property to others
(including all end-user agreements) since January 1, 2004, are in full force and
effect unless otherwise terminated in accordance with the terms of such licenses
or arrangements and there has been no material default by the Company or

                                       17
<PAGE>

any of the Subsidiaries thereunder and, to the Company's knowledge, there is no
material default by any other party thereto.

             (g) The Company and the Subsidiaries have taken all steps required
in accordance with commercially reasonable business practice to establish and
preserve their ownership in their owned Intellectual Property and to keep
confidential all trade secrets developed by or belonging to the Company or the
Subsidiaries which has not been patented or copyrighted. To the Company's
knowledge, none of the employees of the Company or any of the Subsidiaries has
any agreements or arrangements with former employers of such employees relating
to any Intellectual Property of such employers, which materially interfere or
conflict with the performance of such employee's duties for the Company or the
Subsidiaries or result in any former employers of such employees having any
rights in, or claims on, the Company's or any of the Subsidiaries' Intellectual
Property. Except as set forth on Schedule 3.11, each current and former employee
of the Company and of each of the Subsidiaries has executed agreements regarding
confidentiality, proprietary information and assignment of inventions to the
Company or the Subsidiaries, each independent contractor or consultant of the
Company and of each of the Subsidiaries has executed agreements regarding
confidentiality and proprietary information, and neither the Company nor any of
the Subsidiaries has received written notice that any employee, consultant or
independent contractor is in violation of any agreement or in breach of any
agreement or arrangement with former or present employers relating to
proprietary information or assignment of inventions. Without limiting the
foregoing: (i) the Company and each of the Subsidiaries has taken reasonable
security measures to guard against unauthorized disclosure or use of any of its
Intellectual Property that is confidential or proprietary; and (ii) the Company
has no reason to believe that any Person (including, without limitation, any
former employee or consultant of the Company or of any of the Subsidiaries) has
unauthorized possession of any of its trade secrets, or any part thereof, or
that any Person has obtained unauthorized access to any of its trade secrets. To
the Company's knowledge, the Company and each of the Subsidiaries has complied
in all material respects with its respective obligations pursuant to all
agreements relating to Intellectual Property rights that are the subject of
licenses granted by third parties, except for any non-compliance that has not
had or would not reasonably be expected to have a Material Adverse Effect.

         3.12 Registration Rights; Rights of Participation. Except as described
on Schedule 3.12 hereto, (A) the Company has not granted or agreed to grant to
any person or entity any rights (including "piggy-back" registration rights) to
have any securities of the Company registered with the Commission or any other
governmental authority which has not been satisfied in full prior or waived to
the date hereof and (B) no person or entity, including, but not limited to,
current or former shareholders of the Company, underwriters, brokers, agents or
other third parties, has any right of first refusal, preemptive right, right of
participation, anti-dilutive right or any similar right to participate in, or to
receive securities or other assets of the Company as a result of the
transactions contemplated by this Agreement or the other Transaction Documents.

         3.13 Solicitation; Other Issuances of Securities. Neither the Company
nor any of the Subsidiaries or Affiliates, nor any person acting on its or their
behalf, (i) has engaged in any form of general solicitation or general
advertising (within the meaning of Regulation D) in connection with the offer or
sale of the Securities, or (ii) has, directly or indirectly, made any offers or
sales of any

                                       18
<PAGE>

security or the right to purchase any security, or solicited any offers to buy
any security or any such right, under circumstances that would require
registration of the Securities under the Securities Act.

         3.14 Fees. Except as described on Schedule 3.14 hereto, the Company is
not obligated to pay any brokers, finders or financial advisory fees or
commissions to any underwriter, broker, agent or other representative in
connection with the transactions contemplated hereby. The Company will indemnify
and hold harmless such Investor from and against any claim by any person or
entity alleging that such Investor is obligated to pay any such compensation,
fee, cost or related expenditure in connection with the transactions
contemplated hereby.

         3.15 Foreign Corrupt Practices. Neither the Company, any of the
Subsidiaries nor, to the knowledge of the Company, any director, officer, agent,
employee or other person acting on behalf of the Company or any of the
Subsidiaries, has (i) used any corporate funds for any unlawful contribution,
gift, entertainment or other unlawful expenses relating to political activity,
(ii) made any direct or indirect unlawful payment to any foreign or domestic
government official or employee including, without limitation, any bribe,
rebate, payoff, influence payment, kickback or other unlawful payment, or (iii)
violated any provision of the Foreign Corrupt Practices Act of 1977, as amended.

         3.16 Key Employees. Each Key Employee is currently serving in the
capacity described in the Disclosure Documents. The Company has no knowledge of
any fact or circumstance (including without limitation (i) the terms of any
agreement to which such person is a party or any litigation in which such person
is or may become involved and (ii) any illness or medical condition that could
reasonably be expected to result in the disability or incapacity of such person)
that would limit or prevent any such person from serving in such capacity on a
full-time basis in the foreseeable future, or of any intention on the part of
any such person to limit or terminate his or her employment with the Company.

         3.17 Employee Matters. There is no strike, labor dispute or union
organization activities pending or, to the knowledge of the Company, threatened
between it and its employees. No employees of the Company belong to any union or
collective bargaining unit.

         3.18 Environment. To the Company's knowledge, except as disclosed in
the Disclosure Documents, the Company and the Subsidiaries have no liabilities
under any Environmental Law nor, to the Company's knowledge, do any factors
exist that are reasonably likely to give rise to any such liability, affecting
any of the properties owned or leased by the Company or any of the Subsidiaries
that, individually or in the aggregate, has had or would reasonably be expected
to have a Material Adverse Effect. Neither the Company nor any of the
Subsidiaries has violated any Environmental Law applicable to it now or
previously in effect, other than such violations or infringements that,
individually or in the aggregate, have not had and would not reasonably be
expected to have a Material Adverse Effect.

         3.19 ERISA. The Company is in compliance in all material respects with
the presently applicable provisions of ERISA and the United States Internal
Revenue Code of 1986, as amended, with respect to each Pension Plan except in
any such case for any such matters that, individually or in the aggregate, have
not had, and would not reasonably be expected to have, a Material Adverse
Effect.

                                       19
<PAGE>

         3.20 Disclosure. The representations, warranties and written statements
contained in the Disclosure Documents, this Agreement and the other Transaction
Documents and in the certificates, exhibits and schedules delivered to such
Investor by the Company pursuant to this Agreement and the other Transaction
Documents and in connection with such Investor's due diligence investigation of
the Company, taken as a whole, do not contain any untrue statement of a material
fact, and do not omit to state a material fact required to be stated therein or
necessary in order to make such representations, warranties or statements not
misleading in light of the circumstances under which they were made. Except for
the terms of this Agreement and the other Transaction Documents, neither the
Company nor any Person acting on its behalf or at its direction has provided
such Investor with material non-public information. Following the issuance of
the press release in accordance with Section 4.1(c) hereof, to the Company's
knowledge, such Investor will not possess any material non-public information
concerning the Company as a result of information provided directly to such
Investor by the Company or its agents or representatives. The Company
acknowledges that each Investor is relying on the representations,
acknowledgments and agreements made by the Company in Section 3 hereof and
elsewhere in this Agreement in making investing, trading and/or other decisions
concerning the Company's securities.

         3.21 Insurance. The Company maintains insurance for itself and the
Subsidiaries in such amounts and covering such losses and risks as is reasonably
sufficient and customary in the businesses in which the Company and the
Subsidiaries are engaged, except where the failure to maintain such insurance
has not had or would not reasonably be expected to have a Material Adverse
Effect. No notice of cancellation has been received for any of such policies and
the Company is in compliance in all material respects with all of the terms and
conditions thereof. The Company has no reason to believe that it will not be
able to renew its existing insurance coverage as and when such coverage expires
or to obtain similar coverage from similar insurers as may be necessary to
continue to conduct its business as currently conducted without a significant
increase in cost (other than cost increases generally affecting the market for
such insurance). Without limiting the generality of the foregoing, the Company
maintains Director's and Officer's insurance in the amount set forth on Schedule
3.21.

         3.22 Property. Neither the Company nor any Subsidiary owns any real
Property. The Company and the Subsidiaries have valid and legal title to all
personal Property owned by them, in each case free and clear of all Liens,
except for Permitted Liens. To the Company's knowledge, any Property held under
lease by the Company and the Subsidiaries is held by them under valid,
subsisting and enforceable leases with such exceptions as are not material and
do not materially interfere with the use made or proposed to be made of such
Property by the Company and the Subsidiaries.

         3.23 Regulatory Permits. The Company and the Subsidiaries possess all
certificates, authorizations and permits issued by the appropriate federal,
state or foreign regulatory authorities necessary to conduct their respective
businesses, except where the failure to have any such authorization or permit
would not have a Material Adverse Effect, and neither the Company nor any such
Subsidiary has received any notice of proceedings relating to the revocation or
modification of any such certificate, authorization or permit.

                                       20

         3.24 Exchange Act Registration; Listing. The Company's Common Stock is
registered pursuant to Section 12(g) of the Exchange Act and the Company has
taken no action designed to, or which, to the knowledge of the Company, would
reasonably be expected to have the effect of, terminating the registration of
the Common Stock under the Exchange Act. The Company currently meets the
eligibility requirements for quotation of the Common Stock on the OTC Bulletin
Board, and has not received any notice from the NASD that it does not currently
satisfy such requirements or that such continued quotation is in any way
threatened.

         3.25 Investment Company Status. The Company is not, and immediately
after receipt of payment for the Debentures and the Warrants issued under this
Agreement will not be, an "investment company" or an entity "controlled" by an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended (the "Investment Company Act"), and shall conduct its business in a
manner so that it will not become subject to the Investment Company Act.

         3.26 Transfer Taxes. No stock transfer or other taxes (other than
income taxes) are required to be paid in connection with the issuance and sale
of any of the Securities, other than such taxes for which the Company has
established appropriate reserves and intends to pay in full on or before the
Initial Closing.

         3.27 Sarbanes-Oxley Act; Internal Controls and Procedures. The Company
is in compliance in all material respects with all applicable requirements of
the Sarbanes-Oxley Act of 2002 and all applicable rules and regulations
promulgated by the Commission thereunder that are effective as of the date
hereof, except as has not had and would not reasonably be expected to have a
Material Adverse Effect. Except as set forth in the Disclosure Documents, the
Company maintains internal accounting controls, policies and procedures, and
such books and records as are reasonably designed to provide reasonable
assurance that (i) all transactions to which the Company or any Subsidiary is a
party or by which its properties are bound are effected by a duly authorized
employee or agent of the Company, supervised by and acting within the scope of
the authority granted by the Company's senior management; (ii) the recorded
accounting of the Company's consolidated assets is compared with existing assets
at regular intervals; and (iii) all transactions to which the Company or any
Subsidiary is a party, or by which its properties are bound, are recorded (and
such records maintained) in accordance with all Government Requirements and as
may be necessary or appropriate to ensure that the financial statements of the
Company are prepared in accordance with GAAP.

         3.28 Transactions with Interested Persons. Except as set forth in
Schedule 3.28, no officer, director or employee of the Company or any of the
Subsidiaries is or has made any arrangements with the Company or any of the
Subsidiaries to become a party to any transaction with the Company or any
Subsidiary (other than for services as employees, consultants, officers and
directors), including any contract, agreement or other arrangement providing for
the furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Company, any entity in
which any officer, director, or any such employee has a substantial interest or
is an officer, director, trustee or partner.

         3.29 Customers and Suppliers. The relationships of the Company and the
Subsidiaries with the material customers and suppliers of the Company and the
Subsidiaries taken as a whole, are maintained on commercially reasonable terms.
To the Company's knowledge, no customer or supplier of the Company or any of the
Subsidiaries has any plan or intention to terminate any agreement with the
Company or such Subsidiary, which termination would reasonably be expected to
have a Material Adverse Effect.

         3.30 No Other Agreements. The Company has not, directly or indirectly,
entered into any agreement with or granted any right to any Investor relating to
the terms or conditions of the transactions contemplated by the Transaction
Documents, except as expressly set forth in the Transaction Documents.

             (c) (i) on or prior to 8:30 a.m. (eastern time) on the Business Day

the period beginning on the Execution Date and ending on the Termination Date:

                                       22
<PAGE>

                (a) maintain its corporate existence in good standing;

                (b) pay or discharge before becoming delinquent (a) all taxes,
levies, assessments and governmental charges imposed on it or its income or
profits or any of its Property and (b) all lawful claims for labor, material and
supplies, which, if unpaid, might become a Lien upon any of its Property, except
where the failure to do so would not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect; provided, however,
that the Company shall not be required to pay or discharge any tax, levy,
assessment or governmental charge, or claim for labor, material or supplies,
whose amount, applicability or validity is being contested in good faith by
appropriate proceedings being diligently pursued and for which adequate reserves
have been established under GAAP;

                (c) comply with all Governmental Requirements applicable to the

                (d) comply with all agreements, documents and instruments
binding on it or affecting its Properties or business, including, without
limitation, all Material Contracts, except for instances of noncompliance that
would not reasonably be expected to have, individually or in the aggregate, a
Material Adverse Effect; provided, however, that the Company shall not be
required to comply with any Governmental Requirements, the applicability or
validity of which is being contested in good faith by appropriate proceedings
being diligently pursued and for which adequate reserves have been established
under GAAP;

                (e) provide each Investor with copies of all materials sent to
its shareholders at the same time as such materials are delivered to such
shareholders;

                (f) timely file with the Commission all reports required to be
filed pursuant to the Exchange Act and refrain from terminating its status as an
issuer required by the Exchange Act to file reports thereunder even if the
Exchange Act or the rules or regulations thereunder would permit such
termination;

                (g) take commercially reasonable steps to restrict each of the
Company's Key Employees from selling shares of Common Stock prior to the later
to occur of (i) the Initial Effective Date and (ii) if the Option Closing
occurs, the Subsequent Effective Date (each as defined in the Registration
Rights Agreement), other than in connection with any 10b-5(1) trading plans in
effect as of the Execution Date and disclosed to each Investor in writing; and

                (h) use commercially reasonable efforts to maintain adequate
insurance coverage (including D&O insurance) for the Company and each
Subsidiary.

         4.3 Reservation of Common Stock. The Company shall, on the Initial
Closing Date, have a number of shares of Common Stock (the "Reserved Amount")
authorized and reserved for issuance to the Investors free from any preemptive
rights that, on such Closing Date, is not less than two hundred percent (200%)
of the sum of (A) the number of Conversion Shares issuable upon conversion of
all of the Debentures issued or issuable at or prior

                                       23
<PAGE>

to the Initial Closing plus (B) the number of Warrant Shares issuable upon
exercise of all of the Warrants issued or issuable at or prior to the Initial
Closing, in each case without regard to any limitation or restriction on such
conversion or exercise that may be set forth in the Debentures or the Warrants.
The Reserved Amount shall be allocated in accordance with each Investor's Pro
Rata Share. In the event that an Investor shall sell or otherwise transfer any
of such Investor's Debentures or Warrants, each transferee shall be allocated a
pro rata portion of such transferor's Reserved Amount. Any portion of the
Reserved Amount allocated to any Investor or other Person which no longer holds
any Debentures or Warrants shall be reallocated to the remaining Investors pro
rata based on the number of Registrable Securities held by such Investors at
such time. In the event that the Reserved Amount is insufficient at any time to
cover one hundred and fifty percent (150%) of the Registrable Securities
issuable upon the conversion of the Debentures and the exercise of the Warrants
(without regard to any restriction on such conversion or exercise), the Company
shall take such action (including without limitation holding a meeting of its
shareholders) to increase the Reserved Amount to cover two hundred percent
(200%) of the Registrable Securities issuable upon such conversion and
exercise), such increase to be effective not later than the thirtieth (30th) day
(or sixtieth (60th) day, in the event shareholder approval is required for such
increase) following the Company's receipt of written notice of such deficiency.
While any Debentures or Warrants are outstanding, the Company shall not reduce
the Reserved Amount without obtaining the prior written consent of each
Investor.

         4.4 Use of Proceeds. The Company shall use the proceeds from the sale
of the Debentures and Warrants as specified on Schedule 4.4 hereof; provided,
that the Company shall not use any of such proceeds (i) to pay any dividend or
make any distribution on any of its equity securities, or (ii) to repay any loan
made to or incurred by any Key Employee or any other officer or director of the
Company.

         4.5 Limitation on Debt and Liens. During the period beginning on the
Execution Date and ending on the Termination Date, the Company shall refrain,
and shall ensure that each of the Subsidiaries refrains, (a) from incurring any
Debt (including without limitation by issuing any Debt securities) or increasing
the amount of any existing line of credit or other Debt facility beyond the
amount outstanding on the date hereof, other than Permitted Debt, and (b) from
granting, establishing or maintaining any Lien on any of its assets, including
without limitation any pledge of securities owned or held by it (including
without limitation any securities issued by any such Subsidiary), other than
Permitted Liens.

         4.6 Restricted Payments. During the period beginning on the Execution
Date and ending on the Termination Date, the Company will not, nor will it
permit any Subsidiary of the Company to, make any Restricted Payments, except
that:

                (a) the Company may make scheduled payments of principal and
interest accrued on any Permitted Debt; and

                (b) Subsidiaries of the Company may make Restricted Payments to
the Company;

provided, however, that no Restricted Payments may be made pursuant to clause
(a) or (b) above if an Event of Default (or an event or circumstance that with
the giving of notice or lapse of time

                                       24
<PAGE>

              (a) Offered Securities. From the Effective Date through the
Termination Date, the Company will not, directly or indirectly, effect a
Subsequent Placement, unless in each such case the Company shall have first
offered to sell to the Investors at least thirty five percent (35%) of the
securities being offered in such Subsequent Placement (the securities being
offered to the Investors being referred to herein as the "Offered Securities").
The Company shall offer to sell to each Investor such Investor's Pro Rata Share
of the Offered Securities (the "Basic Amount"), at a price and on such other
terms as shall have been specified by the Company in writing delivered to such
Investor (the "Offer"), which Offer by its terms shall remain open and

                                       25
<PAGE>

irrevocable for a period of not less than ten (10) Business Days from such
Investor's receipt of the terms of the Offer in writing (the "Offer Period").

              (b) Notice of Acceptance. Each Investor that wishes to accept the
Offer shall deliver written notice thereof (a "Notice of Acceptance") to the
Company prior to the expiration of the Offer Period, specifying the Basic Amount
that the Investor elects to purchase.

              (c) Permitted Sales Of Refused Securities. In the event that
Notices of Acceptance are not timely delivered by the Investors in respect of
all the Offered Securities within the time frames required by paragraph (b)
above, the Company shall have forty-five (45) days from the expiration of the
Offer Period to close the sale of all or any part of such Offered Securities as
to which a Notice of Acceptance has not been given by an Investor (the "Refused
Securities") to the Person or Persons specified in the Offer, but only upon
terms and conditions, including, without limitation, unit price and interest
rates (if applicable), which are, in the aggregate, no more favorable to such
other Person or Persons or less favorable to the Company than those set forth in
the Offer.

              (d) Closing. Upon the closing of the purchase and sale of Offered
Securities, each Investor shall purchase from the Company, and the Company shall
sell to such Investor, the number of Offered Securities specified in the Notice
of Acceptance delivered by such Investor. The purchase by the Investors of any
Offered Securities is subject in all cases to the preparation, execution and
delivery by the Company and the Investors of a purchase agreement relating to
such Offered Securities on the same terms and conditions applicable to other
Persons purchasing the Offered Securities.

              (e) Further Sale. In each case, any Offered Securities not
purchased by the Investors or other Person or Persons in accordance herewith may
not be sold or otherwise disposed of by the Company until they are again offered
to the Investors under the procedures specified herein.

         4.11 Transactions with Affiliates. The Company agrees that any
transaction or arrangement between it or any of the Subsidiaries and any
Affiliate or employee of the Company shall be effected on an arms' length basis
and shall be approved by the Board of Directors, including a majority of the
Company's directors not having an interest in such transaction.

         4.12 Use of Investor Name. Except as may be required by applicable law
and/or this Agreement, the Company shall not use, directly or indirectly, any
Investor's name or the name of any of its Affiliates in any advertisement,
announcement, press release or other similar communication unless it has
received the prior written consent of such Investor or its Affiliate, as the
case may be, for the specific use contemplated or as otherwise required by
applicable law or regulation.

         4.13 Company's Instructions to Transfer Agent. On or prior to the
Initial Closing Date, the Company shall execute and deliver irrevocable written
instructions to the transfer agent for its Common Stock (the "Transfer Agent"),
and provide each Investor with a copy thereof, directing the Transfer Agent (i)
to issue certificates representing Conversion Shares upon conversion of the

                                       26
<PAGE>

Debentures and receipt of a valid Conversion Notice (as defined in the
Debentures) from an Investor, in the amount specified in such Conversion Notice,
in the name of such Investor or its nominee, (ii) to issue certificates
representing Warrant Shares upon exercise of the Warrants and (iii) to deliver
such certificates to such Investor no later than the close of business on the
third (3rd) business day following the related Conversion Date (as defined in
the Debentures) or Exercise Date (as defined in the Warrant), as the case may
be. Such certificates may bear legends pursuant to applicable provisions of this
Agreement or applicable law. The Company shall instruct the transfer agent that,
in lieu of delivering physical certificates representing shares of Common Stock
to an Investor upon conversion of the Debentures, or exercise of the Warrants,
and as long as the Transfer Agent is a participant in the Depository Trust
Company ("DTC") Fast Automated Securities Transfer program, and such Investor
has not informed the Company that it wishes to receive physical certificates
therefor, and no restrictive legend is required to appear on any physical
certificate if issued, the transfer agent may effect delivery of Conversion
Shares or Warrant Shares, as the case may be, by crediting the account of such
Investor or its nominee at DTC for the number of shares for which delivery is
required hereunder within the time frame specified above for delivery of
certificates. The Company represents to and agrees with each Investor that it
will not give any instruction to the Transfer Agent that will conflict with the
foregoing instruction or otherwise restrict such Investor's right to convert the
Debentures or to receive Conversion Shares in accordance with the terms of the
Debentures or to exercise the Warrant or to receive Warrant Shares upon exercise
of the Warrants. In the event that the Company's relationship with the Transfer
Agent should be terminated for any reason, the Company shall use its
commercially reasonable efforts to cause the Transfer Agent to continue acting
as transfer agent pursuant to the terms hereof until such time that a successor
transfer agent is appointed by the Company and receives the instructions
described above.

         4.14 Limitations on Disposition. No Investor shall sell, transfer,
assign or dispose of any Securities, unless:

              (a) there is then in effect an effective registration statement
under the Securities Act covering such proposed disposition and such disposition
is made in accordance with such registration statement; or

              (b) such Investor has notified the Company in writing of any such
disposition and furnished the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration
of such Securities under the Securities Act; provided, however, that no such
opinion of counsel will be required (A) if the sale, transfer or assignment is
made to an Affiliate of such Investor in compliance with applicable securities
laws, provided that such Affiliate provides the Company with customary
accredited investor and investment representations and agrees to be bound by the
terms and conditions of this Agreement, (B) if the sale, transfer or assignment
is made pursuant to Rule 144 and such Investor provides the Company with
customary representations and/or other evidence reasonably satisfactory to the
Company that the proposed transaction satisfies the requirements of Rule 144, or
(C) in connection with a bona fide pledge or hypothecation of any Securities
under a margin arrangement with a broker-dealer or other financial institution
or the sale of any such Securities by such broker-dealer or other financial
institution following such Investor's default under such margin arrangement.

         4.15 Disclosure of Information. The Company agrees that it will not at
any time following the Execution Date disclose material non-public information
to any Investor without first obtaining such Investor's written consent to such
disclosure.

         4.16 Cash Collateral Deposit. On or before the Initial Closing Date,
the Company will deposit the Collateral Amount with the Collateral Agent as
required by the terms of the Cash Collateral Agreement.

         4.17 Indemnification of Investors. The Company will indemnify and hold
each Investor and its directors, managers, officers, shareholders, members,
partners, employees and agents (each, an "Investor Party") harmless from any and
all losses, liabilities, obligations, claims, contingencies, damages, costs and
expenses, including all judgments, amounts paid in settlements, court costs and
reasonable attorneys' fees and costs of investigation that any such Investor
Party may suffer or incur as a result of or relating to (a) any breach of any of
the representations, warranties, covenants or agreements made by the Company in
this Agreement or in the other Transaction Documents or (b) any action
instituted against an Investor, or any of them or their respective Affiliates,
by any shareholder of the Company who is not an Affiliate of such Investor, with
respect to any of the transactions contemplated by the Transaction Documents
(unless such action is based upon a breach of such Investor's representation,
warranties or covenants under the Transaction Documents or any agreements or
understandings such Investor may have with any such shareholder or any
violations by such Investor of state or federal securities laws or any conduct
by such Investor which constitutes fraud, gross negligence, willful misconduct
or malfeasance). If any action shall be brought against any Investor Party in
respect of which indemnity may be sought pursuant to this Agreement, such
Investor Party shall promptly notify the Company in writing, and the Company
shall have the right to assume the defense thereof with counsel of its own
choosing. Any Investor Party shall have the right to employ separate counsel in
any such action and participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Investor Party except
to the extent that (i) the employment thereof has been specifically authorized
by the Company in writing, (ii) the Company has failed after a reasonable period
of time following such Investor Party's written request that it do so, to assume
such defense and to employ counsel or (iii) in such action there is, in the
reasonable opinion of such separate counsel, a material conflict on any material
issue between the position of the Company and the position of such Investor
Party. The Company will not be liable to any Investor Party under this Agreement
(i) for any settlement by an Investor Party effected without the Company's prior
written consent, which shall not be unreasonably withheld or delayed; or (ii) to
the extent, but only to the extent that a loss, claim, damage or liability is
attributable to such Investor Party's wrongful actions or omissions, or gross
negligence or to such Investor Party's breach of any of the representations,
warranties, covenants or agreements made by such Investor in this Agreement or
in the other Transaction Documents.

         4.18 Short Sale Restriction. Each Investor agrees that, during a Notice
Period (as defined in the Debentures) it will refrain from engaging in any short
sale that, when aggregated with all other short sales effected by such Investor
during such Notice Period, would exceed the number of Amortization Stock Option
Shares issuable to such Investor with respect to such Notice Period. For
purposes hereof, the term "short sale" shall have the definition contained in
Rule 200 of Regulation SHO under the Exchange Act.

                          that restrains or prohibits the consummation of the

                          respects as of such date as if made on such date
                          (except that to the extent that any such
                          representation or warranty relates to a particular
                          date, such representation or warranty shall be true
                          and correct in all material respects as of that
                          particular date);

             5.3.2        the Company shall have complied with or performed in

                          of the Option Closing, it being understood that such
                          Investor may rely on such certificate as though it
                          were a representation and warranty of the Company made
                          herein;

             5.3.4        the Company shall have delivered to such Investor an

                          hereto as Exhibit H hereto and otherwise reasonably
                          acceptable to such Investor;

             5.3.5        the Company shall have delivered to such Investor duly
                          executed certificates representing the Option
                          Debenture and the Option Warrant;

             5.3.6        there shall have occurred no material adverse change
                          in the Company's consolidated business or financial
                          condition since the date of the Company's most recent
                          financial statements contained in the Disclosure
                          Documents;

             5.3.7        the Company shall have authorized and reserved for
                          issuance at least two hundred percent (200%) of the

                          upon conversion of all of the Debentures and exercise
                          of all of the Warrants, including the Option

                          and Option Warrants (such number to be determined
                          without regard to any restriction on such conversion
                          or exercise);

             5.3.8        there shall be no injunction, restraining order or
                          decree of any nature of any court or Government
                          Authority of competent jurisdiction that is in effect
                          that restrains or prohibits the consummation of the
                          transactions contemplated hereby and by the other
                          Transaction Documents; and

             5.3.9        the Initial Transaction Documents, the Subordination
                          Agreement and (to the extent effective) the Contingent
                          Guaranty shall be in full force and effect and no
                          default, or event or occurrence that with the giving
                          of notice or lapse of time (or both) would constitute
                          a default, under any such agreement or instrument has
                          occurred.

         5.4 Conditions to Company's Obligations at the Option Closing. The
Company's obligations to effect the Option Closing with each Investor are
conditioned upon the fulfillment (or waiver by the Company in its sole and
absolute discretion) of each of the following events as of the Option Closing
Date:

             5.4.1        the representations and warranties of such Investor
                          set forth in this Agreement and in the Transaction

                          respects as of such date as if made on such date
                          (except that to the extent that any such
                          representation or warranty relates to a particular
                          date, such representation or warranty shall be true
                          and correct in all material respects as of that
                          particular date);

             5.4.2        such Investor shall have complied with or performed
                          all of the agreements, obligations and conditions set

                          complied with or performed by such Investor on or
                          before the Option Closing;

             5.4.3        there shall be no injunction, restraining order or
                          decree of any nature of any court or Government
                          Authority of competent jurisdiction that is in effect
                          that restrains or prohibits the consummation of the
                          transactions contemplated hereby and by the
                          Transaction Documents; and

6. MISCELLANEOUS.

         6.1 Survival; Severability. The representations, warranties and
covenants made by the parties herein and in the other Transaction Documents
shall survive each Closing notwithstanding any due diligence investigation made
by or on behalf of the party seeking to rely thereon. In the event that any
provision of this Agreement becomes or is declared by a court of competent
jurisdiction to be illegal, unenforceable or void, this Agreement shall continue
in full force and effect without said provision; provided that in such case the
parties shall negotiate in good faith to replace such provision with a new
provision which is not illegal, unenforceable or void, as long as such new
provision does not materially change the economic benefits of this Agreement to
the parties.

         6.2 Successors and Assigns. The terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective successors and
permitted assigns of the parties. Nothing in this Agreement, express or implied,
is intended to confer upon any party other than the parties hereto or their
respective successors and permitted assigns any rights, remedies, obligations or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement. After the Initial Closing, each Investor may assign its
rights and obligations hereunder, in connection with any private sale or
transfer of the Debentures or Warrants in accordance with the terms hereof, as
long as, as a condition precedent to such transfer, the transferee executes an
acknowledgment agreeing to be bound by the applicable provisions of this
Agreement, in which case the term "Investor" shall be deemed to refer to such
transferee as though such transferee were an original signatory hereto. The
Company may not assign its rights or obligations under this Agreement.

         6.3 No Reliance. Each party acknowledges that (i) it has such knowledge
in business and financial matters as to be fully capable of evaluating this
Agreement, the other Transaction Documents and the transactions contemplated
hereby and thereby, (ii) it is not relying on any advice or representation of
any other party in connection with entering into this Agreement, the other
Transaction Documents or such transactions (other than the representations made
in this Agreement or the other Transaction Documents), (iii) it has not received
from any other party any assurance or guarantee as to the merits (whether legal,
regulatory, tax, financial or otherwise) of entering into this Agreement or the
other Transaction Documents or the performance of its obligations hereunder and
thereunder, and (iv) it has consulted with its own legal, regulatory, tax,
business, investment, financial and accounting advisors to the extent that it
has deemed necessary, and has entered into this Agreement and the other
Transaction Documents based on its own independent judgment and on the advice of
its advisors as it has deemed necessary, and not on any view (whether written or
oral) expressed by any other party.

         6.4 Independent Nature of Investors' Obligations and Rights. The
obligations of each Investor hereunder are several and not joint with the
obligations of the other Investors hereunder, and no Investor shall be
responsible in any way for the performance of the obligations of any other
Investor hereunder. Nothing contained herein or in any other agreement or
document delivered at any Closing, and no action taken by any Investor pursuant
hereto or thereto, shall be deemed to constitute the Investors as a partnership,
an association, a joint venture or any other kind of entity, or a "group" as
described in Section 13(d) of the Exchange Act, or create a presumption

                                       34
<PAGE>

that the Investors are in any way acting in concert with respect to such
obligations or the transactions contemplated by this Agreement. Each Investor
has been represented by its own separate counsel in connection with the
transactions contemplated hereby, shall be entitled to protect and enforce its
rights, including without limitation rights arising out of this Agreement or the
other Transaction Documents, individually, and shall not be required to be join
any other Investor as an additional party in any proceeding for such purpose.

         6.5 Injunctive Relief. Each Investor, on the one hand, and the Company,
on the other hand, each acknowledges and agrees that a breach by it of its
obligations hereunder will cause irreparable harm to the non-breaching party and
that the remedy or remedies at law for any such breach will be inadequate and
agrees, in the event of any such breach, in addition to all other available
remedies, the non-breaching party shall be entitled to an injunction restraining
any breach and requiring immediate and specific performance of such obligations
without the necessity of showing economic loss.

         6.6 Governing Law; Jurisdiction. This Agreement shall be governed by
and construed under the laws of the State of New York applicable to contracts
made and to be performed entirely within the State of New York. Each party
hereby irrevocably submits to the non-exclusive jurisdiction of the state and
federal courts sitting in the City and County of New York for the adjudication
of any dispute hereunder or in connection herewith or with any transaction
contemplated hereby 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, that such suit, action or proceeding is
brought in an inconvenient forum or that the venue of such suit, action or
proceeding is improper. Each party hereby irrevocably waives personal service of
process and consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address in effect for
notices to it under this Agreement and agrees that such service shall constitute
good and sufficient service of process and notice thereof. Nothing contained
herein shall be deemed to limit in any way any right to serve process in any
manner permitted by law.

         6.7 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument. This Agreement may be
executed and delivered by facsimile transmission.

         6.8 Headings. The headings used in this Agreement are used for
convenience only and are not to be considered in construing or interpreting this
Agreement.

         6.9 Notices. Any notice, demand or request required or permitted to be
given by the Company or the Investors pursuant to the terms of this Agreement
shall be in writing and shall be deemed delivered (i) when delivered personally
or by verifiable facsimile transmission, unless such delivery is made on a day
that is not a Business Day, in which case such delivery will be deemed to be
made on the next succeeding Business Day and (ii) on the next Business Day after
timely delivery to an overnight courier , addressed as follows:
