              -----------

Securities involves a significant degree of risk.

         (e)  Governmental Review. The Buyer understands that no United States

federal or state agency or any other government or governmental agency has
passed upon or made any recommendation or endorsement of the Securities.

         (f)  Transfer or Re-sale. The Buyer understands that (i) except as
              -------------------
provided in the Registration Rights Agreement, the sale or re-sale of the

applicable state securities laws, and the Securities may not be transferred
unless (a) the Securities are sold pursuant to an effective registration
statement under the 1933 Act, (b) the Buyer shall have delivered to the Company
an opinion of counsel (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions) to the effect that
the Securities to be sold or transferred may be sold or transferred pursuant to
an exemption from such registration, (c) the Securities are sold or transferred
to an "affiliate" (as defined in Rule 144 promulgated under the 1933 Act (or a

<PAGE>

and further, if said Rule is not applicable, any re-sale of such Securities
under circumstances in which the seller (or the person through whom the sale is
made) may be deemed to be an underwriter (as that term is defined in the 1933
Act) may require compliance with some other exemption under the 1933 Act or the
rules and regulations of the SEC thereunder; and (iii) neither the Company nor
any other person is under any obligation to register such Securities under the
1933 Act or any state securities laws or to comply with the terms and conditions
of any exemption thereunder (in each case, other than pursuant to the
Registration Rights Agreement). Notwithstanding the foregoing or anything else
contained herein to the contrary, the Securities may be pledged as collateral in
connection with a bona fide margin account or other lending arrangement.
                  ---- ----

         (g)  Legends. The Buyer understands that the Preferred Shares and the
              -------

Agreement or otherwise may be sold pursuant to Rule 144 without any restriction
as to the number of securities as of a particular date that can then be
immediately sold, the Conversion Shares and Warrant Shares, may bear a
restrictive legend in substantially the following form (and a stop-transfer
order may be placed against transfer of the certificates for such Securities):

         "The securities represented by this certificate have not been
         registered under the Securities Act of 1933, as amended.  The
         securities may not be sold, transferred or assigned in the
         absence of an effective registration statement for the
         securities under said Act, or an opinion of counsel, in form,
         substance and scope customary for opinions of counsel in
         comparable transactions, that registration is not required
         under said Act or unless sold pursuant to Rule 144 under said
         Act."

         The legend set forth above shall be removed and the Company shall
issue a certificate without such legend to the holder of any Security upon which
it is stamped, if, unless otherwise required by applicable state securities
laws, (a) such Security is registered for sale under an effective registration
statement filed under the 1933 Act or otherwise may be sold pursuant to Rule 144
without any restriction as to the number of securities as of a particular date
that can then be immediately sold, or (b) such holder provides the Company with
an opinion of counsel, in form, substance and scope customary for opinions of
counsel in comparable transactions, to the effect that a public sale or transfer
of such Security may be made without registration under the 1933 Act and such
sale or transfer is effected or (c) such holder provides the Company with
reasonable assurances that such Security can be sold pursuant to Rule 144.  The
Buyer agrees to sell all Securities, including those represented by a
certificate(s) from which the legend has been removed, in compliance with
applicable prospectus delivery requirements, if any.

this representation signed by the Company's Chief Executive or Chief Financial
Officer on behalf of the Company as of the Closing Date.

         (d)  Issuance of Shares. The Preferred Shares are duly authorized and,
              ------------------
upon issuance in accordance with the terms of this Agreement, will be validly
issued, fully paid and non-assessable, and free from all taxes, liens, claims

otherwise pursuant to the Warrants. The Company's directors and executive
officers have studied and fully understand the nature of the Securities being
sold hereunder. The Company further acknowledges that its obligation to issue
Conversion Shares and Warrant Shares upon conversion of the Preferred Shares or
exercise of the Warrants in accordance with this Agreement, the Certificate of
Designation and the Warrants is absolute and unconditional regardless of the
dilutive effect that such issuance may have on the ownership interests of other
stockholders of the Company. Taking the foregoing into account, the Company's
Board of Directors has determined, in its good faith business judgment, that the
issuance of the Securities hereunder and under the Certificate of Designation
and the Warrants and the consummation of the transactions contemplated hereby
and thereby are in the best interest of the Company and its stockholders.

         (f)  Series of Preferred Stock. The terms, designations, powers,

Agreement, the Registration Rights Agreement and the Warrants by the Company and
the consummation by the Company of the transactions contemplated hereby and
thereby (including, without limitation, the filing of the Certificate of
Designation and the issuance and reservation for issuance, as applicable, of the
Preferred Shares, Conversion Shares and Warrant Shares) will not (i) conflict
with or result in a violation of any provision of the Certificate of
Incorporation or By-laws or (ii) violate or conflict with, or result in a breach

rights of termination, amendment, acceleration or cancellation of, any
agreement, indenture, patent, patent license or instrument to which the Company
or any of its Subsidiaries is a party, or (iii) result in a violation of any
law, rule, regulation, order, judgment or decree (including federal and state
securities laws and regulations and regulations of any self-regulatory
organizations to which the Company or its securities are subject) applicable to
the Company or any of its Subsidiaries or by which any property or asset of the
Company or any of its Subsidiaries is bound or affected (except for such
conflicts, defaults, terminations, amendments, accelerations, cancellations and
violations as would not, individually or in the aggregate, have a Material
Adverse Effect). Neither the Company nor any of its Subsidiaries is in violation
of its Certificate of Incorporation, By-laws or other organizational documents
and neither the Company nor any of its Subsidiaries is in default (and no event
has

                                       7
<PAGE>

occurred which with notice or lapse of time or both could put the Company or any
of its Subsidiaries in default) under, and neither the Company nor any of its
Subsidiaries has taken any action or failed to take any action that would give
to others any rights of termination, amendment, acceleration or cancellation of,
any agreement, indenture or instrument to which the Company or any of its
Subsidiaries is a party or by which any property or assets of the Company or any
of its Subsidiaries is bound or affected, except for possible defaults as would
not, individually or in the aggregate, have a Material Adverse Effect. The
businesses of the Company and its Subsidiaries, if any, are not being conducted,
and shall not be conducted so long as a Buyer owns any of the Securities, in
violation of any law, ordinance or regulation of any governmental entity. Except
as specifically contemplated by this Agreement and as required under the 1933
Act and any applicable state securities laws, the Company is not required to
obtain any consent, authorization or order of, or make any filing or
registration with, any court, governmental agency, regulatory agency, self
regulatory organization or stock market or any third party in order for it to
execute, deliver or perform any of its obligations under this Agreement, the
Registration Rights Agreement or the Warrants in accordance with the terms
hereof or thereof or to issue and sell the Preferred Shares and Warrants in
accordance with the terms hereof and to issue the Conversion Shares upon
conversion of or otherwise pursuant to the Preferred Shares and the Warrant
Shares upon exercise of or otherwise pursuant to the Warrants. Except as
disclosed in Schedule 3(g) of the Disclosure Statement, all consents,
authorizations, orders, filings and registrations which the Company is required
to obtain pursuant to the preceding sentence have been obtained or effected on

requirements of the American Stock Exchange (the "AMEX") and does not reasonably
anticipate that the Common Stock will be delisted by the AMEX in the foreseeable
future. The Company and its Subsidiaries are unaware of any facts or
circumstances which might give rise to any of the foregoing.

     contemplated to be operated in the future); there is no claim or action by

     to conduct its business as now operated (and, except as set forth in
     Schedule 3(k) of the Disclosure Statement, to the best of the Company's

     is unaware of any facts or
                                       9

     and sequencing) from, into and between the 20th and 21st centuries,
     including the years 1999 and 2000, and leap-year calculations, and will not
     malfunction, cease to function, or provide invalid or incorrect results as
     a result of the date or time data, to the extent that other information
     technology, used in combination with the Information Technology, properly
     exchanges date and time data with it.

         (l)  No Materially Adverse Contracts, Etc. Neither the Company nor any
              ------------------------------------

business upon terms no less favorable

                                       10

officers, directors, or employees of the Company is presently a party to any

capacity of arm's length purchasers with respect to this Agreement and the
transactions contemplated hereby. The Company further acknowledges that no Buyer
is acting as a financial advisor or fiduciary of the Company (or in any similar
capacity) with respect to this Agreement and the transactions contemplated
hereby and that any statement made by any Buyer or any of their respective
representatives or agents in connection with this Agreement and the transactions
contemplated hereby is not advice or a recommendation and is merely incidental
to the Buyers' purchase of the Securities and has not been relied upon by the
Company, its officers or directors in any way. The Company further represents to
each Buyer that the Company's decision to enter into this Agreement has been
based solely on the independent evaluation of the Company and its
representatives.

         (q)  No Integrated Offering. Neither the Company, nor any of its
              ----------------------
affiliates, nor any person acting on its or their behalf, has directly or

in possession of all franchises, grants, authorizations, licenses, permits,
easements, variances, exemptions, consents, certificates, approvals and orders
necessary to own, lease and operate its properties and to carry on its business
as it is now being conducted (collectively, the "Company Permits"), and there is
no action pending or, to the knowledge of the Company, threatened regarding
suspension or cancellation of any of the Company Permits. Neither the Company
nor any of its Subsidiaries is in conflict with, or in default or violation of,
any of the Company Permits, except for any such conflicts, defaults or
violations which, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect. Since December 31, 2000, neither the
Company nor any of its Subsidiaries has received any notification with respect
to possible conflicts, defaults or violations of applicable laws, except for
notices relating to possible conflicts, defaults or violations, which conflicts,
defaults or violations would not have a Material Adverse Effect.

         (t)  Environmental Matters.
              ---------------------

              (i)    Except as set forth in Schedule 3(t) of the Disclosure

     releases of any material into the environment, actions, activities,
     circumstances, conditions, events, incidents, or contractual obligations
     which may give rise to any common law environmental liability or any
     liability under the Comprehensive Environmental Response, Compensation and
     Liability Act of 1980 or similar federal, state, local or foreign laws and
     neither the Company nor any of its Subsidiaries has received any notice
     with respect to any of the foregoing, nor is any action pending or, to the
     Company's knowledge, threatened in connection with any of the foregoing.
     The term "Environmental Laws" means all federal, state, local or foreign
     laws relating to pollution or protection of human health or the environment
     (including, without limitation, ambient air, surface water, groundwater,
     land surface or subsurface strata), including, without limitation, laws
     relating to emissions, discharges, releases or threatened releases of
     chemicals, pollutants contaminants, or toxic or hazardous substances or
     wastes (collectively, "Hazardous Materials") into the environment, or
     otherwise relating to the manufacture, processing, distribution, use,
     treatment, storage, disposal, transport or handling of Hazardous Materials,
     as well as all authorizations, codes, decrees, demands or demand letters,
     injunctions, judgments, licenses, notices or notice letters, orders,
     permits, plans or regulations issued, entered, promulgated or approved
     thereunder.

              (ii)   Other than those that are or were stored, used or disposed
     of in compliance with applicable law, no Hazardous Materials are contained
     on or about any real property currently owned, leased or used by the
     Company or any of its Subsidiaries, and no Hazardous Materials were
     released on or about any real property previously owned, leased or used by
     the Company or any of its Subsidiaries during the period the property was
     owned,

                                       12
<PAGE>

     leased or used by the Company or any of its Subsidiaries during the period
     the property was owned, leased or used by the Company or any of its
     Subsidiaries, except in the normal course of the Company's or any of its
     Subsidiaries' business.

               (iii)  Except as set forth in Schedule 3(t) of the Disclosure
     Statement, there are no underground storage tanks on or under any real
     property owned, leased or used by the Company or any of its Subsidiaries
     that are not in compliance with applicable law.

          (u) Title to Property.  The Company and its Subsidiaries have good and
              -----------------
marketable title in fee simple to all real property and good and marketable
title to all personal property owned by them which is material to the business
of the Company and its Subsidiaries, in each case free and clear of all liens,
encumbrances and defects except such as are described in Schedule 3(u) of the
Disclosure Statement or such as would not have a Material Adverse Effect.  Any
real property and facilities held under lease by the Company and its
Subsidiaries are held by them under valid, subsisting and enforceable leases
with such exceptions as would not have a Material Adverse Effect.

          (v) Insurance.  The Company and each of its Subsidiaries are insured
              ---------
by insurers of recognized financial responsibility against such losses and risks
and in such amounts as management of the Company believes to be prudent and
customary in the businesses in which the Company and its Subsidiaries are
engaged.  Neither the Company nor any such Subsidiary has any 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 its business at a cost that would not have a Material
Adverse Effect.

          (w) Internal Accounting Controls.  The Company and each of its
              ----------------------------
Subsidiaries maintain a system of internal accounting controls sufficient, in
the judgment of the Company's board of directors, to provide reasonable
assurance that (i) transactions are executed in accordance with management's
general or specific authorizations, (ii) transactions are recorded as necessary
to permit preparation of financial statements in conformity with generally
accepted accounting principles and to maintain asset accountability, (iii)
access to assets is permitted only in accordance with management's general or
specific authorization and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

          (x) Foreign Corrupt Practices.  Neither the Company, nor any of its
              -------------------------
Subsidiaries, nor any director, officer, agent, employee or other person acting
on behalf of the Company or any Subsidiary has, in the course of his actions
for, or on behalf of, the Company, used any corporate funds for any unlawful
contribution, gift, entertainment or other unlawful expenses relating to
political activity; made any direct or indirect unlawful payment to any foreign
or domestic government official or employee from corporate funds; violated or is
in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977;
or made any bribe, rebate, payoff, influence payment, kickback or other unlawful
payment to any foreign or domestic government official or employee.

<PAGE>

          (y) Solvency.  The Company (both before and after giving effect to the
              --------
transactions contemplated by this Agreement) is solvent (i.e., its assets have a
                                                         ----
fair market value in excess of the amount required to pay its probable
liabilities on its existing debts as they become absolute and matured) and
currently the Company has no information that would lead it to reasonably
conclude that the Company would not have the ability to, nor does it intend to
take any action that would impair its ability to, pay its debts from time to
time incurred in connection therewith as such debts mature. The Company did not
receive a qualified opinion from its auditors with respect to its most recent
fiscal year end and does not anticipate or know of any basis upon which its
auditors might issue a qualified opinion in respect of its current fiscal year.

          (z) No Investment Company.  The Company is not, and upon the issuance
              ---------------------

of Designation will not be an "investment company" required to be registered
under the Investment Company Act of 1940 (an "Investment Company").  The Company
is not controlled by an Investment Company.

     4.   COVENANTS.
          ---------

          (a) Best Efforts.  The parties shall use their best efforts to satisfy

          (b) Form D; Blue Sky Laws.  The Company agrees to file a Form D with
              ---------------------
respect to the Securities as required under Regulation D and to provide a copy

before the Closing Date, take such action as the Company shall reasonably
determine is necessary to qualify the Securities for sale to the Buyers at the
Closing pursuant to this Agreement under applicable securities or "blue sky"
laws of the states of the United States (or to obtain an exemption from such
qualification), and shall provide evidence of any such action so taken to each
Buyer on or prior to the Closing Date.

          (c) Reporting Status; Eligibility to Use Form S-3; Press Release.  The
              ------------------------------------------------------------
Company's Common Stock is registered under Section 12(g) of the 1934 Act.  So
long as any Buyer beneficially owns any of the Securities, the Company shall
timely file all reports required to be filed with the SEC pursuant to the 1934
Act, and the Company shall not terminate its status as an issuer required to
file reports under the 1934 Act even if the 1934 Act or the rules and
regulations thereunder would permit such termination.  The Company will take all
necessary action to meet the "registrant eligibility" requirements set forth in
the general instructions to Form S-3.  The Company shall issue a press release
describing the material terms of the transactions contemplated hereby as soon as
practicable following the Closing Date but in no event later than one (1)
Trading Day (as defined in the Certificate of Designation) following the Closing
Date, and shall file with the SEC a Current Report on Form 8-K describing the
material terms of the transactions contemplated hereby (and attaching as
exhibits thereto this Agreement, the Registration Rights Agreement, the
Certificate of Designation and the Warrants) within three (3) Trading Days of
the Closing Date, which press release and Form 8-K shall be subject to prior
review by the Buyers.

          (d) Use of Proceeds.  The Company shall use the proceeds from the sale
              ---------------

4(d) of the Disclosure

                                       14
<PAGE>

Statement attached hereto and made a part hereof and shall not, directly or
indirectly, use such proceeds for any loan to or investment in any other
corporation, partnership, enterprise or other person (except in connection with
its currently existing direct or indirect Subsidiaries).

          (e) Additional Equity Capital.  Subject to the exceptions described
              -------------------------
below, the Company will not, without the prior written consent of a majority-in-
interest of the Buyers, negotiate or contract with any party to obtain
additional equity financing (including debt financing with an equity component),
during the period beginning on the Closing Date and ending ninety (90) days from
the Closing Date (the limitations referred to in this sentence are the "Capital
Raising Limitations"). The Capital Raising Limitations shall not apply to any
transaction involving (i) issuances of securities in a firm commitment
underwritten public offering (excluding a continuous offering pursuant to Rule
415 under the 1933 Act) or (ii) issuances of securities as consideration for a
merger, consolidation or purchase of assets, or in connection with any strategic
partnership or joint venture (the primary purpose of which is not to raise
equity capital), or in connection with the disposition or acquisition of a
business, product or license by the Company. The Capital Raising Limitations
also shall not apply to the issuance of securities upon exercise of conversion
of the Company's options, warrants or other convertible securities outstanding
as of the date hereof or to the grant of additional options or warrants, or the
issuance of additional securities, under any Company stock option or restricted
stock plan approved by the stockholders of the Company.

          (f) Expenses.  The Company shall reimburse Rose Glen Capital
              --------
Management, L.P. ("Rose Glen") for all expenses incurred by it in connection
with the negotiation, preparation, execution, delivery and performance of this
Agreement and the other agreements to be executed in connection herewith,
including, without limitation, attorneys' and consultants' fees and expenses and
travel expenses.  The Company's obligation to reimburse Rose Glen's expenses
under this Section 4(f) shall be limited to Fifteen Thousand Dollars ($15,000)
of which Seven Thousand Five Hundred Dollars ($7,500) was advanced previously.

          (g) Financial Information.  The Company agrees to send the following
              ---------------------
reports to each Buyer until such Buyer transfers, assigns, or sells all of the
Securities: (i) within ten (10) days after the filing with the SEC, a copy of
its Annual Report on Form 10-K, its Quarterly Reports on Form 10-Q and any
Current Reports on Form 8-K; (ii) within one (1) day after release, copies of
all press releases issued by the Company or any of its Subsidiaries; and (iii)
contemporaneously with the making available or giving to the stockholders of the
Company, copies of any notices or other information the Company makes available
or gives to such stockholders.

          (h) Reservation of Shares.  The Company shall at all times have
              ---------------------
authorized, and reserved for the purpose of issuance, a sufficient number of
shares of Common Stock to provide for the full conversion of the outstanding
Preferred Shares and issuance of the Conversion Shares in connection with the
conversion of Preferred Shares (based on the Conversion Price (as defined in the
Certificate of Designation) in effect from time to time) and as otherwise
required by the Certificate of Designation and the full exercise of the Warrants
and issuance of the Warrant Shares in connection therewith (based on the
Exercise Price (as defined in the Warrants) of the Warrants in effect from time
to time). The Company shall not reduce the number of shares of Common Stock
reserved for issuance upon conversion of or otherwise pursuant to the Preferred
Shares and upon

                                       15
<PAGE>

exercise of or otherwise pursuant to the Warrants without the consent of each
Buyer. The Company shall use its best efforts at all times to maintain the
number of shares of Common Stock so reserved for issuance at no less than one
and one-fourth (1 1/4) times the number that is then actually issuable upon full
conversion of the Preferred Shares (based on the Conversion Price (as defined in
the Certificate of Designation) in effect from time to time) and full exercise
of the Warrants (based on the Exercise Price (as defined in the Warrants) of the
Warrants in effect from time to time). If at any time the number of shares of
Common Stock authorized and reserved for issuance is below the number of
Conversion Shares issued and issuable upon conversion of or otherwise pursuant
to the Preferred Shares (based on the Conversion Price (as defined in the
Certificate of Designation) in effect from time to time) and the aggregate
number of Warrant Shares issued and issuable upon exercise of or otherwise
pursuant to the Warrants (based on the Exercise Price (as defined in the
Warrants) of the Warrants in effect from time to time), the Company will
promptly take all corporate action necessary to authorize and reserve a
sufficient number of shares, including, without limitation, calling a special
meeting of stockholders to authorize additional shares to meet the Company's
obligations under this Section 4(h), in the case of an insufficient number of
authorized shares, and using its best efforts to obtain stockholder approval of
an increase in such authorized number of shares.

          (i) Listing.  The Company shall promptly secure the listing of the
              -------
Conversion Shares and Warrant Shares upon each national securities exchange or
automated quotation system, if any, upon which shares of Common Stock are then
listed (subject to official notice of issuance) and, so long as any Buyer owns
any of the Securities, shall maintain, so long as any other shares of Common
Stock shall be so listed, such listing of all Conversion Shares and Warrant
Shares from time to time issuable upon conversion of or otherwise pursuant to
the Preferred Shares or exercise of or otherwise pursuant to the Warrants. The
Company will obtain and, so long as any Buyer owns any of the Securities,
maintain the listing and trading of its Common Stock on AMEX, the Nasdaq
National Market ("Nasdaq"), the Nasdaq SmallCap Market ("Nasdaq SmallCap") or
the New York Stock Exchange ("NYSE") and will comply in all respects with the
Company's reporting, filing and other obligations under the bylaws or rules of
the National Association of Securities Dealers ("NASD") and such exchanges, as
applicable. The Company shall promptly provide to each Buyer copies of any
notices it receives from AMEX and any other exchanges or quotation systems on
which the Common Stock is then listed regarding the continued eligibility of the
Common Stock for listing on such exchanges and quotation systems.

          (j) Corporate Existence. So long as a Buyer beneficially owns any
              -------------------
Preferred Shares or Warrants, the Company shall maintain its corporate existence
and shall not merge, consolidate or sell all or substantially all of the
Company's assets, except in the event of a merger or consolidation or sale of
all or substantially all of the Company's assets, where (i) the successor or
acquiring entity and, if an entity different from the successor or acquiring
entity, the entity whose securities into which the Preferred Shares shall become
convertible pursuant to Article VI.C(ii) of the Certificate of Designation), in
such transaction assumes the Company's obligations hereunder and under the
agreements and instruments entered into in connection herewith (including the
Certificate of Designation and the Warrants) and (ii) the entity whose
securities into which the Preferred Shares shall become convertible pursuant to
Article VI.C(ii) of the Certificate of Designation is a publicly

                                       16
<PAGE>

traded corporation whose Common Stock is listed for trading on Nasdaq, Nasdaq
SmallCap, NYSE or AMEX.

          (k) No Integration.  The Company shall not make any offers or sales of
              --------------
any security (other than the Securities) under circumstances that would require
registration of the Securities being offered or sold hereunder under the 1933
Act or cause the offering of Securities to be integrated with any other offering
of securities by the Company for the purpose of any stockholder approval
provision applicable to the Company or its securities.

          (l) No Optional Redemption of Series C 8% Convertible Preferred Stock.
              -----------------------------------------------------------------
The Company covenants and agrees that, prior to May 15, 2002, it shall not,
without the consent of the Buyer, voluntarily redeem any shares of the Series C
8% Convertible Preferred Stock (the "Series C Preferred Stock") pursuant to
Article V.C. of the Company's Certificate of Designation, Preferences and Rights
of Series C 8% Convertible Preferred Stock; provided, however, that the
foregoing covenant shall not prohibit or restrict the Company from effecting any
redemption required pursuant to Articles V.A and V.B of the Company's
Certificate of Designation, Preferences and Rights of Series C 8% Convertible
Preferred Stock.

     5.   TRANSFER AGENT INSTRUCTIONS.  The Company shall issue irrevocable
          ---------------------------
instructions to its transfer agent to issue certificates, registered in the name
of each Buyer or its nominee, for the Conversion Shares and Warrant Shares in
such amounts as specified from time to time by each Buyer to the Company upon
conversion of the Preferred Shares or exercise of the Warrants in accordance
with the terms thereof (the "Irrevocable Transfer Agent Instructions").  Prior
to registration of the Conversion Shares and Warrant Shares under the 1933 Act
or the date on which the Conversion Shares or Warrant Shares may be sold
pursuant to Rule 144 without any restriction as to the number of securities as
of a particular date that can then be immediately sold, all such certificates
shall bear the restrictive legend specified in Section 2(g) of this Agreement.
The Company warrants that no instruction other than the Irrevocable Transfer
Agent Instructions referred to in this Section 5, and stop transfer instructions
to give effect to Section 2(f) hereof (in the case of the Conversion Shares and
Warrant Shares, prior to registration of the Conversion Shares and Warrant
Shares under the 1933 Act or the date on which the Conversion Shares or Warrant
Shares may be sold pursuant to Rule 144 without any restriction as to the number
of securities as of a particular date that can then be immediately sold), will
be given by the Company to its transfer agent and that the Securities shall
otherwise be freely transferable on the books and records of the Company as and
to the extent provided in this Agreement and the Registration Rights Agreement.
Nothing in this Section shall affect in any way the Buyer's obligations and
agreement set forth in Section 2(g) hereof to comply with all applicable
prospectus delivery requirements, if any, upon re-sale of the Securities.  If a
Buyer provides the Company with (i) an opinion of counsel, in form, substance
and scope customary for opinions in comparable transactions, to the effect that
a public sale or transfer of  such  Securities may be made without registration
under the 1933 Act and such sale or transfer is effected or (ii) the Buyer
provides reasonable assurances that the Securities can be sold pursuant to Rule
144, the Company shall permit the transfer, and, in the case of the Conversion
Shares and Warrant Shares, promptly instruct its transfer agent to issue one or
more certificates, free from any restrictive legend, in such name and in such
denominations as specified by such Buyer.

        (g)   Successors and Assigns; Company Right of First Refusal.
              ------------------------------------------------------

               (i) This Agreement shall be binding upon and inure to the benefit
     of the parties and their successors and assigns.  Neither the Company nor
     any Buyer shall assign this Agreement or any rights or obligations
     hereunder without the prior written consent of the other.  Notwithstanding
     the foregoing, subject to Section 2(f) and Section 8(g)(ii), any Buyer may
     assign its rights hereunder to any person that purchases Securities in a
     private transaction from a Buyer or to any of its "affiliates," as that
     term is defined under the 1934 Act, without the consent of the Company.

                                       21
<PAGE>

               (ii) No Buyer may at any time transfer its Securities to any
     person (other than in a transaction otherwise permitted hereunder or to
     "affiliates" as that term is defined in the 1934 Act, to any fund or
     investment vehicle managed or controlled by Rose Glen or its affiliates or
     to a holder of interests in the Buyer upon liquidation of the Buyer's
     assets in accordance with Buyer's governing documents) (a "Proposed
     Transferee") without first offering in writing to sell such Preferred
     Shares and/or Warrants to the Company first at the same price and upon the
     same terms and conditions that are proposed from the transferee (an
     "Offer").  The Offer shall remain open for a period of five (5) business
     days (the "Exercise Period").  If, prior to the end of the Exercise Period,
     the Company does not (i) give written notice of its intent to accept the
     Offer, and (ii) consummate the purchase of the Preferred Shares and/or
     Warrants pursuant to the Offer, such Offer will terminate and the Buyer
     shall be permitted to transfer the Securities to the Proposed Transferee
     identified in the Offer.

          (h) Third Party Beneficiaries.  This Agreement is intended for the
              -------------------------
benefit of the parties hereto and their respective permitted successors and
assigns, and is not for the benefit of, nor may any provision hereof be enforced
by, any other person.

          (i) Survival.  The representations and warranties of the Company and
              --------
the agreements and covenants set forth in Sections 3, 4, 5 and 8 shall survive
the closing hereunder notwithstanding any due diligence investigation conducted
by or on behalf of the Buyers.  The Company agrees to indemnify and hold
harmless each of the Buyers and all their officers, directors, employees and
agents for loss or damage arising as a result of or related to any breach or
alleged breach by the Company of any of its representations, warranties and
covenants set forth in Sections 3 and 4 hereof or any of its covenants and
obligations under this Agreement or the Registration Rights Agreement, including
advancement of expenses as they are incurred.

          (j) Publicity.  The Company and each of the Buyers shall have the
              ---------
right to review a reasonable period of time before issuance of any press
releases, filings with the SEC, NASD or any stock exchange or interdealer
quotation system, or any other public statements with respect to the
transactions contemplated hereby; provided, however, that the Company shall be
                                  --------  -------
entitled, without the prior approval of each of the Buyers, to make any press
release or public filings with respect to such transactions as is required by
applicable law and regulations (although each of the Buyers shall be consulted
by the Company in connection with any such press release or public filing prior
to its release or public filing and shall be provided with a copy thereof and be
given an opportunity to comment thereon).  In addition, the Company agrees that
it will not disclose, and will not include in any public filing or other
announcement, the name of any Buyer, unless expressly agreed to in writing by
such Buyer or unless and until such disclosure is, in the reasonable opinion of
counsel to the Company, required by law or applicable regulation, and then only
to the extent of such requirement.

          (k) Further Assurances.  Each party shall do and perform, or cause to
              ------------------
be done and performed, all such further acts and things, and shall execute and
deliver all such other agreements, certificates, instruments and documents, as
the other party may reasonably request in

                                       22
<PAGE>

order to carry out the intent and accomplish the purposes of this Agreement and
the consummation of the transactions contemplated hereby.

          (l) No Strict Construction.  The language used in this Agreement will
              ----------------------
be deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any party.

          (m) Remedies.  The Company acknowledges that a breach by it of its
              --------
obligations hereunder will cause irreparable harm to each Buyer by vitiating the
intent and purpose of the transactions contemplated hereby.  Accordingly, the
Company acknowledges that the remedy at law for a breach of its obligations
under this Agreement will be inadequate and agrees, in the event of a breach or
threatened breach by the Company of the provisions of this Agreement, that each
Buyer shall be entitled, in addition to all other available remedies in law or
in equity, to an injunction or injunctions to prevent or cure any breaches of
the provisions of this Agreement and to enforce specifically the terms and
provisions of this Agreement, without the necessity of showing economic loss and
without any bond or other security being required.
