                        Representations and Warranties

          Section 2.1  Representations and Warranties of the Company.  In order
                       ---------------------------------------------
to induce the Purchasers to enter into this Agreement and to purchase the Notes,
the Company hereby makes the following representations and warranties to the
Purchasers:

          (a)  Organization, Good Standing and Power.  The Company is a
               -------------------------------------
corporation duly incorporated, validly existing and in good standing under the
laws of the State of Delaware and has the requisite corporate power to own,
lease and operate its properties and assets and to conduct its business as it is
now being conducted. The Company does not have any Subsidiaries (as defined in
Section 2.1(g)) or own securities of any kind in any other entity except as set
forth in the Commission Documents (as defined in Section 2.1(f)) or on Schedule
                                                                       --------
2.1(g) hereto. The Company and each such Subsidiary is duly qualified as a
------
foreign corporation to do business and is in good standing in every jurisdiction
in which the nature of the business conducted or property owned by it makes such
qualification necessary except for any jurisdiction(s) (alone or in the
aggregate) in which the failure to be so qualified will not have a Material
Adverse Effect. For the purposes of this Agreement, "Material Adverse Effect"
                                                     -----------------------
means any adverse effect on the business, operations, properties, prospects or
financial condition of the Company or its Subsidiaries and which is material to
such entity or other entities controlling or controlled by such entity or which
is likely to materially hinder the performance by the Company of its obligations
hereunder and under the other Transaction Documents (as defined in Section
2.1(b) hereof).

          (b)  Authorization; Enforcement.  The Company has the requisite
               --------------------------
corporate power and authority to enter into and perform this Agreement and the
Irrevocable Transfer Agent Instructions (as defined in Section 3.12)
(collectively, the "Transaction Documents") and to issue and sell the Securities
                    ---------------------
in accordance with the terms hereof and the Notes and the Warrants, as
applicable. The execution, delivery and performance of the Transaction Documents
by the Company and the consummation by it of the transactions contemplated
thereby have been duly and validly authorized by all necessary corporate action,
and no further consent or authorization of the Company or its Board of Directors
or stockholders is required. This Agreement has been duly executed and delivered
by the Company. The other Transaction Document will have been duly executed and
delivered by the Company at the Closing. Each of the Transaction Documents

                                      -2-
<PAGE>

constitutes, or shall constitute when executed and delivered, a valid and
binding obligation of the Company enforceable against the Company in accordance
with its terms, except as such enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, liquidation,
conservatorship, receivership or similar laws relating to, or affecting
generally the enforcement of, creditor's rights and remedies or by other
equitable principles of general application.

          (c)  Capitalization.  The authorized capital stock of the Company and
               --------------
the shares thereof currently issued and outstanding as of March 31, 2001 are set
forth on Schedule 2.1(c) hereto. All of the outstanding shares of the Company's
         ---------------
Common Stock and any other security of the Company have been duly and validly
authorized. Except as set forth in this Agreement and as set forth in the
Commission Documents or on Schedule 2.1(c) hereto, no shares of Common Stock or
                           ---------------
any other security of the Company are entitled to preemptive rights or
registration rights and there are no outstanding options, warrants, scrip,
rights to subscribe to, call or commitments of any character whatsoever relating
to, or securities or rights convertible into, any shares of capital stock of the
Company. Furthermore, except as set forth in this Agreement and as set forth on
in the Commission Documents or on Schedule 2.1(c) hereto, there are no
                                  ---------------
contracts, commitments, understandings, or arrangements by which the Company is
or may become bound to issue additional shares of the capital stock of the
Company or options, securities or rights convertible into shares of capital
stock of the Company. Except for customary transfer restrictions contained in
agreements entered into by the Company in order to sell restricted securities or
as provided in the Commission Documents or on Schedule 2.1(c) hereto, the
                                              ---------------
Company is not a party to or bound by any agreement or understanding granting
registration or anti-dilution rights to any person with respect to any of its
equity or debt securities. Except as set forth on Schedule 2.1(c), the Company
                                                  ---------------

Company issued prior to the Closing complied with all applicable federal and
state securities laws, and no holder of such securities has a right of

Adverse Effect. The Company has furnished or made available to the Purchasers

          (d)  Issuance of Securities.  The Notes and the Warrants to be issued
               ----------------------
at the Closing have been duly authorized by all necessary corporate action and,
when paid for or issued in accordance with the terms hereof, the Notes shall be
validly issued and outstanding, free and clear of all liens, encumbrances and
rights of refusal of any kind. When the Warrant Shares are issued and paid for
in accordance with the terms of this Agreement and as set forth in the Warrants,
such shares will be duly authorized by all necessary corporate action and
validly issued and outstanding, fully paid and nonassessable, free and clear of
all liens, encumbrances and rights of refusal of any kind and the holders shall
be entitled to all rights accorded to a holder of Common Stock.

          (e)  No Conflicts.  The execution, delivery and performance of the
               ------------
Transaction Documents by the Company and the consummation by the Company of the
transactions

contemplated hereby and thereby do not and will not (i) violate any provision of
the Company's Certificate or Bylaws or any Subsidiary's comparable charter
documents, (ii) conflict with, or constitute a default (or an event which with
notice or lapse of time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, any
agreement, mortgage, deed of trust, indenture, note, bond, license, lease
agreement, instrument or obligation to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries'
respective properties or assets are bound, (iii) create or impose a lien,
mortgage, security interest, charge or encumbrance of any nature on any property
or asset of the Company or any of its Subsidiaries under any agreement or any
commitment to which the Company or any of its Subsidiaries is a party or by
which the Company or any of its Subsidiaries is bound or by which any of their
respective properties or assets are bound, or (iv) result in a violation of any
federal, state, local or foreign statute, rule, regulation, order, judgment or
decree (including federal and state securities laws and regulations) applicable
to the Company or any of its Subsidiaries or by which any property or asset of
the Company or any of its Subsidiaries are bound or affected, except, in all
cases other than violations pursuant to clauses (i) or (iv) above, for such
conflicts, defaults, terminations, amendments, acceleration, cancellations and
violations as would not, individually or in the aggregate, have a Material
Adverse Effect. The business of the Company and its Subsidiaries is not being
conducted in violation of any laws, ordinances or regulations of any
governmental entity, except for possible violations which singularly or in the
aggregate do not and will not have a Material Adverse Effect. Neither the
Company nor any of its Subsidiaries is required under federal, state, foreign or
local law, rule or regulation to obtain any consent, authorization or order of,
or make any filing or registration with, any court or governmental agency in
order for it to execute, deliver or perform any of its obligations under the
Transaction Documents or issue and sell the Notes and the Warrant Shares in
accordance with the terms hereof or thereof (other than any filings which may be
required to be made by the Company with the U.S. Securities and Exchange
Commission (the "Commission"), the Nasdaq SmallCap Market ("Nasdaq"), or state
                 ----------                                 ------
securities administrators subsequent to the Closing, or any registration

          (f)  Commission Documents, Financial Statements.  The Common Stock of
               ------------------------------------------
the Company is registered pursuant to Section 12(b) or 12(g) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and, except as disclosed
                                       ------------
on Schedule 2.1(f) hereto, the Company has timely filed all reports, schedules,
   ---------------
forms, statements and other documents required to be filed by it with the
Commission pursuant to the reporting requirements of the Exchange Act, including
material filed pursuant to Section 13(a) or 15(d) of the Exchange Act (all of
the foregoing including filings incorporated by reference therein being referred
to herein as the "Commission Documents"). The Company has delivered or made
                  --------------------
available to the Purchasers true and complete copies of the Commission Documents
filed with the Commission since March 31, 2001. The Company has not provided to
the Purchasers any material non-public information or other information which,
according to applicable law, rule or regulation, should have been disclosed
publicly by the Company but which has not been so disclosed, other than with
respect to the transactions contemplated by this Agreement. The Form 10-QSB for
the fiscal quarter ended March 31, 2001 (the "Form 10-QSB") complied in all
                                              -----------
material respects with the requirements of the Exchange Act and the rules and
regulations of the Commission promulgated thereunder and other federal, state
and local laws, rules and regulations applicable to such documents, and Form 10-
QSB did not contain any untrue statement of a material fact or omitted

                                      -4-
<PAGE>

to state a material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they were
made, not misleading. The financial statements of the Company included in the
Commission Documents comply as to form in all material respects with applicable
accounting requirements and the published rules and regulations of the
Commission or other applicable rules and regulations with respect thereto. Such
financial statements have been prepared in accordance with generally accepted
accounting principles ("GAAP") applied on a consistent basis during the periods
                        ----
involved (except (i) as may be otherwise indicated in such financial statements
or the notes thereto or (ii) in the case of unaudited interim statements, to the
extent they may not include footnotes or may be condensed or summary
statements), and fairly present in all material respects the financial position
of the Company and its Subsidiaries as of the dates thereof and the results of
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments).

          (g)  Subsidiaries.  The Commission Documents or Schedule 2.1(g)
               ------------                               ---------------
hereto set forth each Subsidiary of the Company, showing the jurisdiction of its
incorporation or organization and showing the percentage of each person's
ownership of the outstanding stock or other interests of such Subsidiary. For
the purposes of this Agreement, "Subsidiary" shall mean any corporation or other
                                 ----------
entity of which at least a majority of the securities or other ownership
interest having ordinary voting power (absolutely or contingently) for the
election of directors or other persons performing similar functions are at the
time owned directly or indirectly by the Company and/or any of its other
Subsidiaries. All of the outstanding shares of capital stock of each Subsidiary
have been duly authorized and validly issued, and are fully paid and
nonassessable. There are no outstanding preemptive, conversion or other rights,
options, warrants or agreements granted or issued by or binding upon any
Subsidiary for the purchase or acquisition of any shares of capital stock of any
Subsidiary or any other securities convertible into, exchangeable for or
evidencing the rights to subscribe for any shares of such capital stock. Neither
the Company nor any Subsidiary is subject to any obligation (contingent or
otherwise) to repurchase or otherwise acquire or retire any shares of the
capital stock of any Subsidiary or any convertible securities, rights, warrants
or options of the type described in the preceding sentence except as set forth
on Schedule 2.1(g) hereto. Neither the Company nor any Subsidiary is party to,
   ---------------
nor has any knowledge of, any agreement restricting the voting or transfer of
any shares of the capital stock of any Subsidiary.

          (h)  No Material Adverse Change.  Since March 31, 2001, the Company
               --------------------------
has not experienced or suffered any Material Adverse Effect, except as disclosed
in the Commission Documents or on Schedule 2.1(h) hereto.
                                  ---------------

          (i)  No Undisclosed Liabilities. Except as disclosed in the Commission
               --------------------------
Documents or on Schedule 2.1(i) hereto, neither the Company nor any of its

amendment, acceleration or cancellation of any agreement, indenture or
instrument to which the Purchaser is a party, or result in a violation of any
law, rule, or regulation, or any order, judgment or decree of any court or
governmental agency applicable to the Purchaser or its properties (except for

indefinitely unless such Securities are registered under the Securities Act or
an exemption from registration is available. The Purchaser acknowledges that
such person is familiar with Rule 144 of the rules and regulations of the
Commission, as amended, promulgated pursuant to the Securities Act ("Rule 144"),
                                                                     --------
and that the Purchaser has been advised that Rule 144 permits resales only under
certain circumstances. The Purchaser understands that to the extent that Rule
144 is not available, the Purchaser will be unable to sell any Securities
without either registration under the Securities Act or the existence of another
exemption from such registration requirement.

          (f)  General. The Purchaser understands that the Securities are being
               -------
offered and sold in reliance on a transactional exemption from the registration
requirements of federal and state securities laws and the Company is relying
upon the truth and accuracy of the representations, warranties, agreements,
acknowledgments and understandings of the Purchaser set forth herein in order to
determine the applicability of such exemptions and the suitability of the
Purchaser to acquire the Securities. Purchaser understands that no United States
federal or state agency or any government or governmental agency has passed upon
or made any recommendation or endorsement of the Securities.

          (g)  Opportunities for Additional Information. The Purchaser
               ----------------------------------------
acknowledges that the Purchaser has had the opportunity to ask questions of and
receive answers from, or obtain additional information from, the executive
officers of the Company concerning the financial and other affairs of the
Company, and to the extent deemed necessary in light of the Purchaser's personal
knowledge of the Company's affairs, the Purchaser has asked such questions and
received answers to the full satisfaction of the Purchaser, and the Purchaser
desires to invest in the Company.

          (h)  No General Solicitation. The Purchaser acknowledges that the
               -----------------------
Securities were not offered to the Purchaser by means of any form of general or
public solicitation or general advertising, or publicly disseminated
advertisements or sales literature, including (i) any advertisement, article,
notice or other communication published in any newspaper, magazine, or similar
media, or broadcast over television or radio, or (ii) any seminar or meeting to
which the Purchaser was invited by any of the foregoing means of communications.

          (i)  Accredited Investor. The Purchaser is an accredited investor (as
               -------------------
defined in Rule 501 of Regulation D), and the Purchaser has such experience in
business and financial matters that it is capable of evaluating the merits and
risks of an investment in the Securities. The Purchaser acknowledges that an
investment in the Securities is speculative and involves a high degree of risk.

Exchange Act or Securities Act, except as permitted herein. The Company will

          Section 3.3  Inspection Rights. The Company shall permit, during
                       -----------------

Purchasers or any employees, agents or representatives thereof, so long as the
Purchasers shall be obligated hereunder to purchase the Notes or shall
beneficially own any Notes, or shall own Warrant Shares or Warrants to purchase

delivery of such notices or information to such holders of Common Stock.

          Section 3.7  Amendments. The Company shall not amend or waive any
                       ----------
provision of the Certificate or Bylaws of the Company in any way that would
adversely affect the exercise rights, voting rights, prepayment rights or
redemption rights of the holders of the Notes or the Warrants.

          Section 3.8  Other Agreements. The Company shall not enter into any
                       ----------------
agreement in which the terms of such agreement would restrict or impair the
right or ability to perform of the Company or any Subsidiary under any
Transaction Document.

          Section 3.9  Distributions. So long as any Securities remain
                       -------------
outstanding, the Company agrees that it shall not, without the prior written
consent of the Purchasers, which consent may be granted or denied in the sole
discretion of the Purchasers (i) declare or pay any dividends (other than a
stock dividend or stock split) or make any distributions to any holder(s) of
Common Stock or (ii) purchase or otherwise acquire for value, directly or
indirectly, any Common Stock or other equity security of the Company.

          Section 3.10  Subsequent Financings; Right of First Refusal. (a) So
                        ---------------------------------------------
long as the Notes remain outstanding, the Company covenants and agrees that it
will not, without the prior written consent of the Purchasers, enter into any
subsequent offer or sale to, or exchange with (or other type of distribution
to), any third party (a "Subsequent Financing"), of Common Stock or any
                         --------------------
securities convertible, exercisable or exchangeable into Common Stock, including
debt securities (collectively, the "Financing Securities") other than a
                                    --------------------
Permitted Financing (as defined hereinafter). For purposes of this Agreement,
"Permitted Financing" shall mean any transaction involving the Company's (i)
 -------------------
issuance of any Financing Securities (other than for cash) in connection with a
Strategic Merger (as defined in Section 5(e) of the Notes), (ii) issuance of

                                     -15-
<PAGE>

Common Stock or the issuance of options to purchase Common Stock as such is
related to any employee stock ownership plan, or (iii) any transaction where the
first use of the proceeds from such transaction would be used to redeem all of
the Notes in accordance with Section 5 of the Notes.

          (b)  So long as the Notes remain outstanding and commencing ninety
(90) days after the date hereof, the Company covenants and agrees to promptly
notify (in no event later than five (5) days after making or receiving an
applicable offer) in writing (a "Rights Notice") the Purchasers of the terms and
                                 -------------
conditions of any proposed Subsequent Financing. The Rights Notice shall
describe, in reasonable detail, the proposed Subsequent Financing, the proposed
closing date of the Subsequent Financing, which shall be within thirty (30)
calendar days from the date of the Rights Notice, including, without limitation,
all of the terms and conditions thereof. The Rights Notice shall provide the
Purchasers an option (the "Rights Option") during the thirty (30) calendar day
                           -------------
period following delivery of the Rights Notice (the "Option Period") to purchase
                                                     -------------
such amount as the Company and the Purchasers may agree to up to such
Purchaser's pro rata portion of the Purchase Price, of the securities being
offered in such Subsequent Financing on the same, absolute terms and conditions
as contemplated by such Subsequent Financing (the "First Refusal Rights").
                                                   --------------------
Delivery of any Rights Notice constitutes a representation and warranty by the
Company that there are no other material terms and conditions, arrangements,
agreements or otherwise except for those disclosed in the Rights Notice, to
provide additional compensation to any party participating in any proposed
Subsequent Financing, including, but not limited to, additional compensation
based on changes in the Purchase Price or any type of reset or adjustment of a
purchase or conversion price or to issue additional securities at any time after
the closing date of a Subsequent Financing. If the Company does not receive
notice of exercise of the Rights Option from the Purchasers within the Option
Period, the Company shall have the right to close the Subsequent Financing on
the scheduled closing date with a third party; provided that all of the terms
                                               --------
and conditions of the closing are the same as those provided to the Purchasers
in the Rights Notice. If the closing of the proposed Subsequent Financing does
not occur on that date, any closing of the contemplated Subsequent Financing or
any other Subsequent Financing shall be subject to all of the provisions of this
Section 3.10, including, without limitation, the delivery of a new Rights
Notice.

          (c)  If the Company fails to complete a Strategic Merger within ninety
(90) days of the date hereof, the Company shall use its best efforts to enter
into a Subsequent Financing which will provide that the first use of the
proceeds from such transaction will be applied to prepay the Notes in full.

          Section 3.11  Reservation of Shares. As of each Warrant issuance date,
                        ---------------------
the Company shall have reserved out of its authorized and unissued Common Stock,
solely for the purpose of effecting the exercise of the Warrants, a sufficient
number of shares of Common Stock to effect the issuance of the Warrant Shares
issuable upon exercise of such Warrants. So long as any of the Warrants remain
outstanding, the Company shall take all action necessary to at all times have
authorized, and reserved for the purpose of issuance, a sufficient number of
shares of Common Stock to effect the issuance of the Warrant Shares.

          Section 3.12  Transfer Agent Instructions. The Company shall issue
                        ---------------------------
irrevocable instructions to its transfer agent, and any subsequent transfer
agent, to issue certificates,

                                     -16-
<PAGE>

registered in the name of the Purchasers or their respective nominee(s), for the
Warrant Shares in such amounts as specified from time to time by the Purchasers
to the Company upon exercise of the Warrants, in the form of Exhibit E attached
hereto (the "Irrevocable Transfer Agent Instructions"). Prior to registration of
             ---------------------------------------
the Warrant Shares under the Securities Act, all such certificates shall bear
the restrictive legend specified in Section 5.1 of this Agreement. The Company
warrants that no instruction other than the Irrevocable Transfer Agent
Instructions referred to in this Section 3.12 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. Nothing in this Section 3.12 shall affect in any way
the Purchasers' obligations and agreements set forth in Section 5.1 to comply
with all applicable prospectus delivery requirements, if any, upon the resale of
the Warrant Shares. If a Purchaser provides the Company with an opinion of
counsel, in a generally acceptable form, to the effect that a public sale,
assignment or transfer of the Securities may be made without registration under
the Securities Act or the Purchaser provides the Company with reasonable
assurances that the Securities can be sold pursuant to Rule 144 without any
restriction as to the number of securities acquired as of a particular date that
can then be immediately sold, the Company shall permit the transfer, and, in the
case of the Warrant Shares, promptly instruct its transfer agent to issue one or
more certificates in such name and in such denominations as specified by the
Purchaser and without any restrictive legend. The Company acknowledges that a
breach by it of its obligations under this Section 3.12 will cause irreparable
harm to the Purchasers by vitiating the intent and purpose of the transaction
contemplated hereby. Accordingly, the Company acknowledges that the remedy at
law for a breach of its obligations under this Section 3.12 will be inadequate
and agrees, in the event of a breach or threatened breach by the Company of the
provisions of this Section 3.12, that the Purchasers shall be entitled, in
addition to all other available remedies, to an order and/or injunction
restraining any breach and requiring immediate issuance and transfer, without
the necessity of showing economic loss and without any bond or other security
being required.

          Section 3.13  Disposition of Assets. So long as the Notes remain
                        ---------------------
outstanding, neither the Company nor any Subsidiary shall sell, transfer or
otherwise dispose of any of its properties, assets and rights including, without
limitation, its software and intellectual property, to any person except for
sales to customers in the ordinary course of business or with the prior written
consent of the Purchasers.

          Section 3.14  Repayment of Other Indebtedness. So long as the Notes
                        -------------------------------
remain outstanding, the Company shall not repay any indebtedness for borrowed
money owed by the Company to any officer, director, affiliate or insider of the
Company.

          Section 5.1  Legend. Each certificate representing the Notes, the
                       ------
Warrants and the Warrant Shares shall be stamped or otherwise imprinted with a
legend substantially in the following form (in addition to any legend required
by applicable state securities or "blue sky" laws):

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE (THE "SECURITIES")
     HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED (THE "SECURITIES ACT") OR ANY STATE SECURITIES LAWS AND
     MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS
     REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE
     SECURITIES LAWS OR SPEEDCOM WIRELESS CORPORATION SHALL HAVE
     RECEIVED AN OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH
     SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF
     APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

     The Company agrees to reissue certificates representing any of the
Securities, without the legend set forth above if at such time, prior to making
any transfer of any such Securities, such holder thereof shall give written
notice to the Company describing the manner and terms of such transfer and
removal as the Company may reasonably request.  Such proposed transfer will not
be effected until: (a) the Company has notified such holder that either (i) in
the opinion of Company counsel, the registration of such Notes, Warrants or
Warrant Shares under the Securities Act is not required in connection with such
proposed transfer; or (ii) a registration statement under the Securities Act
covering such proposed disposition has been filed by the Company with the
Commission and has become effective under the Securities Act; and (b) the

counsel, the registration or qualification under the securities or "blue sky"
laws of any state is not required in connection with such proposed disposition,
or (ii) compliance with applicable state securities or "blue sky" laws has been
effected.  The Company will use its best efforts to respond to any such notice
from a holder within five (5) days.  In the case of any proposed transfer under
this Section 5, the Company will use reasonable efforts to comply with any such
applicable state securities or "blue sky" laws, but shall in no event be
required, in connection therewith, to qualify to do business in any state where
it is not then qualified or to take any action that would subject it to tax or
to the general service of process in any state where it is not then subject.
The restrictions on transfer contained in Section 5.1 shall be in addition to,
and not by way of limitation of, any other restrictions on transfer contained in
any other section of this Agreement.

          Section 6.1  Termination by Mutual Consent. This Agreement may be
                       -----------------------------
terminated at any time prior to the Closing Date by the mutual written consent
of the Company and the Purchasers.

          Section 6.2  Effect of Termination. In the event of termination by the
                       ---------------------
Company or the Purchasers, written notice thereof shall forthwith be given to
the other party and the transactions contemplated by this Agreement shall be
terminated without further action by either party. If this Agreement is
terminated as provided in Section 6.1 herein, this Agreement shall become void
and of no further force and effect, except for Sections 8.1 and 8.2, and Article
VII herein. Nothing in this Section 6.2 shall be deemed to release the Company
or any Purchaser from any liability for any breach under this Agreement, or to
impair the rights of the Company and the Purchasers to compel specific
performance by the other party of its obligations under this Agreement.

                                  ARTICLE VII

                                Indemnification

          Section 7.1 General Indemnity. The Company agrees to indemnify and
                      -----------------
hold harmless the Purchasers (and their respective directors, officers,
affiliates, agents, successors and assigns) from and against any and all losses,
liabilities, deficiencies, costs, damages and expenses (including, without
limitation, reasonable attorneys' fees, charges and disbursements) incurred by
the Purchasers as a result of any inaccuracy in or breach of the
representations, warranties or covenants made by the Company herein. The
Purchasers severally but not jointly agree to indemnify and hold harmless the
Company and its directors, officers, affiliates, agents, successors and assigns
from and against any and all losses, liabilities, deficiencies, costs, damages
and expenses (including, without limitation, reasonable attorneys' fees, charges
and disbursements) incurred by the Company as result of any inaccuracy in or
breach of the representations, warranties or covenants made by the Purchasers
herein.

          Section 7.2  Indemnification Procedure. Any party entitled to
                       -------------------------
indemnification under this Article VII (an "indemnified party") will give
written notice to the indemnifying party of any matters giving rise to a claim
for indemnification; provided, that the failure of any party entitled to
indemnification hereunder to give notice as provided herein shall not relieve
the indemnifying party of its obligations under this Article VII except to the
extent that the indemnifying party is actually prejudiced by such failure to
give notice. In case any action, proceeding or claim is brought against an
indemnified party in respect of which indemnification is sought hereunder, the
indemnifying party shall be entitled to participate in and, unless in the
reasonable judgment of the indemnified party a conflict of interest between it
and the indemnifying party may exist with respect to such action, proceeding or
claim, to assume the defense thereof with counsel reasonably satisfactory to the
indemnified party. In the event that the indemnifying party advises an
indemnified party that it will contest such a claim for

                                     -21-
<PAGE>

indemnification hereunder, or fails, within thirty (30) days of receipt of any
indemnification notice to notify, in writing, such person of its election to
defend, settle or compromise, at its sole cost and expense, any action,
proceeding or claim (or discontinues its defense at any time after it commences
such defense), then the indemnified party may, at its option, defend, settle or
otherwise compromise or pay such action or claim. In any event, unless and until
the indemnifying party elects in writing to assume and does so assume the
defense of any such claim, proceeding or action, the indemnified party's costs
and expenses arising out of the defense, settlement or compromise of any such
action, claim or proceeding shall be losses subject to indemnification
hereunder. The indemnified party shall cooperate fully with the indemnifying
party in connection with any negotiation or defense of any such action or claim
by the indemnifying party and shall furnish to the indemnifying party all
information reasonably available to the indemnified party which relates to such
action or claim. The indemnifying party shall keep the indemnified party fully
apprised at all times as to the status of the defense or any settlement
negotiations with respect thereto. If the indemnifying party elects to defend
any such action or claim, then the indemnified party shall be entitled to
participate in such defense with counsel of its choice at its sole cost and
expense. The indemnifying party shall not be liable for any settlement of any
action, claim or proceeding effected without its prior written consent.
Notwithstanding anything in this Article VII to the contrary, the indemnifying
party shall not, without the indemnified party's prior written consent, settle
or compromise any claim or consent to entry of any judgment in respect thereof
which imposes any future obligation on the indemnified party or which does not
include, as an unconditional term thereof, the giving by the claimant or the
plaintiff to the indemnified party of a release from all liability in respect of
such claim. The indemnification required by this Article VII shall be made by
periodic payments of the amount thereof during the course of investigation or
defense, as and when bills are received or expense, loss, damage or liability is
incurred, so long as the indemnified party irrevocably agrees to refund such
moneys if it is ultimately determined by a court of competent jurisdiction that
such party was not entitled to indemnification. The indemnity agreements
contained herein shall be in addition to (a) any cause of action or similar
rights of the indemnified party against the indemnifying party or others, and
(b) any liabilities the indemnifying party may be subject to pursuant to the
law.

                                 ARTICLE VIII

                                 Miscellaneous

          Section 8.1  Fees and Expenses. Each party shall pay the fees and
                       -----------------
expenses of its advisors, counsel, accountants and other experts, if any, and
all other expenses, incurred by such party incident to the negotiation,
preparation, execution, delivery and performance of this Agreement, provided,
                                                                    --------
however, that the Company shall pay such fees and expenses set forth on Schedule
-------                                                                 --------
2.1(p) hereto, and all reasonable attorneys' fees and expenses (exclusive of
------
disbursements and out-of-pocket expenses) incurred by the Purchasers in
connection with the preparation, negotiation, execution and delivery of this
Agreement and the other Transaction Documents and the transactions contemplated
thereunder up to $25,000. In addition, the Company shall pay all reasonable fees
and expenses incurred by the Purchasers in connection with any amendments,
modifications or waivers of this Agreement or any of the other Transaction
Documents or incurred in connection with the enforcement of this Agreement and

                                     -22-
<PAGE>

any of the other Transaction Documents, including, without limitation, all
reasonable attorneys' fees, disbursements and expenses.

          Section 8.2  Specific Enforcement; Consent to Jurisdiction.
                       ---------------------------------------------

          (a)  The Company and the Purchasers acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement or the other Transaction Documents were not performed in accordance
with their specific terms or were otherwise breached. It is accordingly agreed
that the parties shall be entitled to an injunction or injunctions to prevent or
cure breaches of the provisions of this Agreement or the other Transaction
Documents and to enforce specifically the terms and provisions hereof or
thereof, this being in addition to any other remedy to which any of them may be
entitled by law or equity.

          (b)  Each of the Company and the Purchasers (i) hereby irrevocably
submits to the jurisdiction of the United States District Court sitting in the
Southern District of New York and the courts of the State of New York located in
New York county for the purposes of any suit, action or proceeding arising out
of or relating to this Agreement or any of the other Transaction Documents or
the transactions contemplated hereby or thereby and (ii) hereby waives, and
agrees not to assert in any such suit, action or proceeding, any claim that it
is not personally subject to the jurisdiction of such court, that the suit,
action or proceeding is brought in an inconvenient forum or that the venue of
the suit, action or proceeding is improper. Each of the Company and the
Purchasers 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 in this
Section 8.2 shall affect or limit any right to serve process in any other manner
permitted by law.

          Section 8.3  Entire Agreement; Amendment. This Agreement and the
                       ---------------------------
Transaction Documents contain the entire understanding and agreement of the
parties with respect to the matters covered hereby and, except as specifically
set forth herein or in the other Transaction Documents, neither the Company nor
the Purchasers make any representation, warranty, covenant or undertaking with
respect to such matters, and they supersede all prior understandings and
agreements with respect to said subject matter, all of which are merged herein.
No provision of this Agreement may be waived or amended other than by a written
instrument signed by the Company and the holders of at least two-thirds (2/3) of
the principal amount of the Notes then outstanding, and no provision hereof may
be waived other than by a written instrument signed by the party against whom
enforcement of any such amendment or waiver is sought. No such amendment shall
be effective to the extent that it applies to less than all of the holders of
the Notes then outstanding. No consideration shall be offered or paid to any
person to amend or consent to a waiver or modification of any provision of any
of the Transaction Documents unless the same consideration is also offered to
all of the parties to the Transaction Documents or holders of Notes, as the case
may be.

          Section 8.4  Notices. Any notice, demand, request, waiver or other
                       -------

                               [FORM OF OPINION]

     1.   The Company is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Delaware and has the requisite
corporate power to own, lease and operate its properties and assets, and to
carry on its business as presently conducted. The Company is duly qualified as a
foreign corporation to do business and is in good standing in every jurisdiction
in which the nature of the business conducted or property owned by it makes such
qualification necessary.

     2.   The Company has the requisite corporate power and authority to enter
into and perform its obligations under the Transaction Documents and to issue
the Notes, the Warrants and the Warrant Shares. The execution, delivery and
performance of each of the Transaction Documents by the Company and the
consummation by it of the transactions contemplated thereby have been duly and
validly authorized by all necessary corporate action and no further consent or
authorization of the Company or its Board of Directors or stockholders is
required. Each of the Transaction Documents have been duly executed and
delivered, and the Notes and the Warrants have been duly executed, issued and
delivered by the Company and each of the Transaction Documents constitutes a
legal, valid and binding obligation of the Company enforceable against the
Company in accordance with its respective terms. The Warrant Shares are not
subject to any preemptive rights under the Certificate of Incorporation or the
Bylaws.

     3.   The Notes have been duly authorized and, when delivered against
payment in full as provided in the Purchase Agreement, will be validly issued,
fully paid and nonassessable. The Warrant Shares, have been duly authorized and
reserved for issuance, and, when delivered upon exercise or against payment in
full as provided in the Warrants, will be validly issued, fully paid and
nonassessable.

     4.   The execution, delivery and performance of and compliance with the
terms of the Transaction Documents and the issuance of the Notes, the Warrants
and the Warrant Shares do not (a) violate any provision of the Certificate of
Incorporation or Bylaws, (b) conflict with, or constitute a default (or an event
which with notice or lapse of time or both would become a default) under, or
give to others any rights of termination, amendment, acceleration or
cancellation of, any material agreement, mortgage, deed of trust, indenture,
note, bond, license, lease agreement, instrument or obligation to which the
Company is a party, (c) create or impose a lien, charge or encumbrance on any
property of the Company under any agreement or any commitment to which the
Company is a party or by which the Company is bound or by which any of its
respective properties or assets are bound, or (d) result in a violation of any
Federal, state, local or foreign statute, rule, regulation, order, judgment,
injunction or decree (including Federal and state securities laws and
regulations) applicable to the Company or by which any property or asset of the
Company is bound or affected, except, in all cases other than violations
pursuant to clauses (a) and (d) above, for such conflicts, default,
terminations, amendments, acceleration, cancellations and violations as would
not, individually or in the aggregate, have a Material Adverse Effect.
<PAGE>

     5.   No consent, approval or authorization of or designation, declaration
or filing with any governmental authority on the part of the Company is required
under Federal, state or local law, rule or regulation in connection with the
valid execution, delivery and performance of the Transaction Documents, or the
offer, sale or issuance of the Notes, the Warrants or the Warrant Shares other
than filings as may be required by the Nasdaq rules and regulations.

     6.   There is no action, suit, claim, investigation or proceeding pending
or threatened against the Company which questions the validity of the Agreement
or the transactions contemplated thereby or any action taken or to be taken
pursuant thereto. There is no action, suit, claim, investigation or proceeding
pending, or to our knowledge, threatened, against or involving the Company or
any of its properties or assets and which, if adversely determined, is
reasonably likely to result in a Material Adverse Effect. There are no
outstanding orders, judgments, injunctions, awards or decrees of any court,
arbitrator or governmental or regulatory body against the Company or any
officers or directors of the Company in their capacities as such.

     7.   Each of the Company and its subsidiaries have all franchises, permits,
licenses, consents and other governmental or regulatory authorizations and
approvals necessary for the conduct of its business as now being conducted by
it, except for such franchises, permits, licenses, consents and other
governmental or regulatory authorizations and approvals, the failure to possess

                                Schedule 2.1(c)
                                ---------------

Authorized Capital Stock:           30,000,000 common shares;  10,000,000
                                    preferred shares
Issued as of June 8, 2001:          9,523,113 common shares; 0 preferred shares

All issued shares as of 3/31/01 were registered shares and free trading, subject
to rules for affiliates under rules 144 and 145.

After June 8, 2001, SPEEDCOM  will issue the following shares:

SRI International:                  150,000 shares

Additionally, SPEEDCOM has issued $462,800 of convertible debt securities which
could result in up to 123,000 shares of additional issuance.  These shares have
been registered.

SPEEDCOM currently has senior secured debt of approximately $40,000, a bridge
loan from Bruce Sanguinetti of $250,000, the $462,800 of convertible debt
referred to above, approximately $200,000 of trade notes payable, plus accrued
expenses and payables in the ordinary course.

Subordinated Promissory Notes in the aggregate principal amount of $3,000,000
dated April 13, 2001.

As of June 8, 2001, SPEEDCOM had outstanding contract rights, including options
and warrants as follows: Employee options granted: 3,639,085; vested: 1,222,201.
The weighted average strike price of the vested employee options is $2.75.
Publicly traded warrants are as disclosed in the company's SEC filings and could
result in approximately 2.2 million shares of dilution if the stock price rises
above $27 before October 7, 2001. Private warrants totalling approximately
230,000 are as disclosed in the company's SEC filings except for 36,500 warrants
issued to Bruce Sanguinetti as partial compensation for his bridge loans. At
$3.00 per share, it is estimated that potential future dilution could total
approximately (under FASB 128) 1,600,000 shares under all vested contract rights
(including certain anti-dilution rights held by SRI and one angel investor) (the
publicly traded warrants have strike prices above $27 per share). Options are
registered either on Form S-4 or S-8.

The McKinney family is under a "lock-up agreement" until December 2001.

Jay Wright is under a "lock-up agreement" until December 2001.

HC Wainwright is entitled to certain warrants as compensation for their
investment banking services.  These warrants will be registered on the Company's
next registration statement filed with the SEC.

U.S. $500,000                                                 New York, New York

          FOR VALUE RECEIVED, the undersigned, Speedcom Wireless Corporation, a
Delaware corporation (the "Company"), hereby promises to pay to the order of
                           -------
S.A.C. Capital Associates or any future permitted holder of this promissory note
(the "Payee"), at the principal office of the Payee set forth herein, or at such
      -----
other place as the holder may designate in writing to the Company, the principal
sum of up to FIVE HUNDRED THOUSAND DOLLARS (U.S. $500,000), or such other amount
as may be outstanding hereunder, together with all accrued but unpaid interest,
in such coin or currency of the United States of America as at the time shall be
legal tender for the payment of public and private debts and in immediately
available funds, as provided in this promissory note (the "Note"). Concurrently
                                                           ----
with the issuance of this Note, the Company is issuing separate notes (the
"Other Notes") to separate investors pursuant to the Purchase Agreement (as
 -----------
defined in Section 3(d) hereof).

          1.   Principal and Interest Payments.
               -------------------------------

               (a)  The Company shall repay in full the entire principal balance
then outstanding under this Note on the first to occur (the "Maturity Date") of:
                                                             -------------
(i) April 17, 2002; or (ii) the acceleration of the obligations as contemplated
by this Note. The Company may prepay all or any part of this Note, together with
the Other Notes, in whole or in part at any time, without penalty or premium, as
set forth in Section 5(d) hereof.

               (b)  Interest on the outstanding principal balance of this Note
shall accrue at a rate of ten percent (10%) per annum. Interest on the
outstanding principal balance of the Note shall be computed on the basis of the
actual number of days elapsed and a year of three hundred and sixty (360) days
and shall be payable by the Company (i) on a quarterly basis, commencing on
September 11, 2001 and on each three-month anniversary thereafter, continuing
<PAGE>

throughout the term of this Note, and (ii) in full on the Maturity Date.
Furthermore, upon the occurrence of an Event of Default, then to the extent
permitted by law, the Company will pay interest to the Payee, payable on demand,
on the outstanding principal balance of the Note from the date of the Event of
Default until payment in full at the rate of fourteen percent (14%) per annum.

               (c)  At the Maturity Date, the outstanding principal amount of
this Note plus all accrued and unpaid interest herein shall be due and payable
in cash or, at the option of the Payee, converted into equity securities which
may be issued in connection with a possible private placement by the Company of
its equity securities to certain institutional investors completed at or prior
to the Maturity Date (the "Proposed Financing"). Upon the conversion of this
                           ------------------
Note, the outstanding principal amount of this Note, together with accrued
interest hereon, shall be deemed to be the consideration for the Payee's
interest in the new equity securities on the Maturity Date.

               (d)  The Company shall use its best efforts to prepare and file
with the Securities and Exchange Commission as soon as possible following the
closing of the Proposed Financing, but in any event no later than sixty (60)
days from the date hereof (the "Filing Date"), a registration statement covering
                                -----------
shares of the Company's common stock underlying the equity securities (the
"Registration Statement"). If the Registration Statement is not filed on or
 ----------------------
prior to the Filing Date, the Company shall pay as liquidated damages for such
failure and not as a penalty to the Payee an amount equal to two percent (2%) of
the purchase price paid by the Payee for this Note for each thirty (30) day
period in which the registration statement is not filed on or prior to the
Filing Date (the "Periodic Amount"). The parties agree that the Periodic Amount
                  ---------------
represents a reasonable estimate on the part of the parties, as of the date of
this Note, of the amount of damages that may be incurred by the Payee if the
Registration Statement is not filed on or prior to the Filing Date.

          2.   Payment on Non-Business Days. Whenever any payment to be made
               ----------------------------
shall be due on a Saturday, Sunday or a public holiday under the laws of the
State of New York, such payment may be due on the next succeeding business day
and such next succeeding day shall be included in the calculation of the amount
of accrued interest payable on such date.

          3.   Events of Default. The occurrence of any of the following events
               -----------------
shall be an "Event of Default" under this Note:
             ----------------

               (a)  the Company shall fail to make the payment of any amount of
any principal outstanding for a period of three (3) business days after the date
such payment shall become due and payable hereunder; or

               (b)  the Company shall fail to make any payment of interest for a
period of three (3) business days after the date such interest shall become due
and payable hereunder; or

                                       2
<PAGE>

               (c)  the Proposed Financing shall fail to have been consummated
by April 17, 2002; or

               (d)  the Company shall fail to make the payment of any fees
and/or liquidated damages under this Note or the Note and Warrant Purchase
Agreement by and among the Company, the Payee, and the other purchasers party
thereto, dated as of the date hereof (the "Purchase Agreement") which failure is
                                           ------------------
not remedied within five (5) business days after the occurrence thereof; or

               (e)  the Company shall default in the performance or observance
of any covenant, condition or agreement contained in any of the Transaction
Documents (as defined in the Purchase Agreement, the "Transaction Documents")
                                                      ---------------------
(or the Company makes an announcement, statement or threat that it does not
intend to honor its obligations under any of the Transaction Documents) and such
default is not fully cured within five (5) business days (other than with
respect to an announcement, statement or threat) after the occurrence thereof in
the case of failure within the Company's control or thirty (30) business days in
the case of a default due to circumstances outside of the Company's control,
after the earlier of (x) the date on which any executive officer of the Company
shall have obtained actual knowledge of such failure (or such announcement,
statement or threat) and (y) the date on which written notice thereof has been
given to the Company by the Payee which is not covered by any other provisions
of this Section 3(e); or

               (f)  any representation, warranty or certification made by the
Company herein or in any of the other Transaction Documents or in any
certificate or financial statement shall prove to have been false or incorrect
or breached in a material respect on the date as of which made; or

               (g)  the Company or any of its Subsidiaries (as defined the
Purchase Agreement, the "Subsidiaries") shall (i) default in any payment of any
                         ------------
amount or amounts of principal of or interest on any Indebtedness (as defined in
the Purchase Agreement, the "Indebtedness") (other than the Indebtedness
                             ------------
hereunder) the aggregate principal amount of which Indebtedness of all such
persons is in excess of $100,000, whether such Indebtedness now exists or shall
hereinafter be created, and such default entitles the holder thereof to declare
such indebtedness to be due and payable, and such indebtedness has not been
discharged in full or such acceleration has not been stayed, rescinded or
annulled within ten (10) business days of such acceleration, or (ii) default in
the observance or performance of any other agreement or condition relating to
any Indebtedness or contained in any instrument or agreement evidencing,
securing or relating thereto, or any other event shall occur or condition exist,
the effect of which default or other event or condition is to cause, or to
permit the holder or holders or beneficiary or beneficiaries of such
Indebtedness to cause with the giving of notice if required, such Indebtedness
to become due prior to its stated maturity; or

               (h)  A judgment or order for the payment of money shall be
rendered against the Company or any Subsidiary in excess of $100,000 in the
aggregate (net of any

                                       3
<PAGE>

applicable insurance coverage) for all such judgments or orders against all such
persons (treating any deductibles, self insurance or retention as not so
covered) that shall not be discharged, and all such judgments and orders remain
outstanding, and there shall be any period of thirty (30) consecutive days
following entry of the judgment or order in excess of $100,000 or the judgment
or order which causes the aggregate amount described above to exceed $100,000
during which a stay of enforcement of such judgment or order, by reason of a
pending appeal or otherwise, shall not be in effect; or

               (i)  an "Event of Default" has occurred and is continuing under
any Other Notes issued to any other holders pursuant to the Purchase Agreement;
or

               (j)  the Company shall (i) apply for or consent to the

court of competent jurisdiction, seeking (i) the liquidation, reorganization,
moratorium, dissolution, winding up, or composition or readjustment of its
debts, (ii) the appointment of a trustee, receiver, custodian, liquidator or the
like of it or of all or any substantial part of its assets or (iii) similar

undismissed, or unstayed and in effect, for a period of thirty (30) consecutive
days or any order for relief shall be entered in an involuntary case under the
Bankruptcy Code or under the comparable laws of any jurisdiction (foreign or

continue undismissed, or unstayed and in effect for a period of thirty (30)
consecutive days.

          4.   Remedies Upon An Event of Default. If an Event of Default shall
               ---------------------------------
have occurred and shall be continuing, the Payee of this Note may at any time at
its option, (a) declare the entire unpaid principal balance of this Note,
together with all interest accrued hereon, due and payable, and thereupon, the
same shall be accelerated and so due and payable, without presentment, demand,
protest, or notice, all of which are hereby expressly unconditionally and
irrevocably waived by the Company; provided, however, that upon the occurrence
                                   --------  -------
of an Event of Default described in (i) Sections 3(j) and (k), the outstanding
principal balance and accrued

                                       4
<PAGE>

interest hereunder shall be automatically due and payable, and (ii) Sections
3(a) through (i), the Payee may demand the prepayment of this Note pursuant to
Section 5 hereof; or (b) exercise or otherwise enforce any one or more of the
Payee's rights, powers, privileges, remedies and interests under this Note or
any of the other Transaction Documents or applicable law. No course of delay on
the part of the Payee shall operate as a waiver thereof or otherwise prejudice
the right of the Payee. No remedy conferred hereby shall be exclusive of any
other remedy referred to herein or now or hereafter available at law, in equity,
by statute or otherwise.

          5.   Prepayment Options.
               ------------------

               (a)  Prepayment. Notwithstanding anything to the contrary
                    ----------
contained herein, the Payee shall have the right, at such Payee's option, to
require the Company to prepay all or a portion of the sum of the outstanding
principal amount and any interest accrued and outstanding under this Note (the
"Prepayment Price"), provided, that such prepayment is requested upon the
 ----------------    --------
occurrence of a Major Transaction (as defined in Section 5(e) below) or a
Triggering Event (as defined in Section 5(e) below). Nothing in this Section
5(a) shall limit the Payee's rights under Section 4 hereof. The Company shall
immediately notify the holders of the Other Notes if the Payee has requested
prepayment pursuant to this Section 5.

               (b)  Mechanics of Prepayment at Option of Payee. At least thirty
                    ------------------------------------------
(30) days prior to the occurrence of a Major Transaction and within one (1) day
after the occurrence of a Major Transaction or a Triggering Event, the Company
shall deliver written notice thereof via facsimile and overnight courier
("Notice of a Prepayment Event") to the Payee and the holders of the Other
  ----------------------------
Notes. At any time on or after the earlier of the Payee's receipt of a Notice of
a Prepayment Event and the Payee becoming aware of a Major Transaction or a
Triggering Event, the Payee may require the Company to prepay all or a portion
of the outstanding principal amount and any interest accrued and outstanding
under this Note by delivering written notice thereof via facsimile and overnight
courier ("Notice of Prepayment at Option of Payee") to the Company, which Notice
          ---------------------------------------
of Prepayment at Option of Payee shall indicate the amount of principal and
interest accrued and outstanding under this Note that the Payee is electing to
have prepaid, the sum of which shall be the Prepayment Price.

               (c)  Payment of Prepayment Price. Upon the Company's receipt of a
                    ---------------------------
Notice of Prepayment at Option of Payee from the Payee, the Company shall
immediately notify the Payee by facsimile of the Company's receipt of a Notice
of Prepayment at Option of Payee and the Payee which has sent such a notice
shall, in the case of a Major Transaction, deliver to the Company this Note
which Payee has elected to have prepaid on or before the consummation or closing
of such Major Transaction and, in the case of a Triggering Event, promptly
submit to the Company this Note which Payee has elected to have prepaid. The
Company shall pay the Prepayment Price to Payee, in the case of a Major
Transaction, at or prior to the closing of the Major Transaction, and, in the
case of a Triggering Event, within five (5) business days after the Company's
receipt of a Notice of Prepayment at Option of Payee; provided that this Note
                                                      --------
shall have been so delivered to the Company. If the Company shall fail to prepay
all of the Prepayment Price (other than pursuant to a dispute as to the
arithmetic calculation of the

                                       5
<PAGE>

Prepayment Price), in addition to any remedy the Payee may have under this Note
and the Purchase Agreement, the Prepayment Price payable in respect of such
unprepaid Notes shall bear interest at the rate of two percent (2.0%) per each
period of thirty (30) consecutive days, pro rated for any period of less than
thirty (30) days until paid in full. Until the Company pays such unpaid
Prepayment Price in full to the Payee, the Payee shall have the option (the

 -------------------------------
Company to promptly return to the Payee this Note that was submitted for
prepayment by Payee under this Section 5(c) and for which the Prepayment Price
has not been paid, by sending written notice thereof to the Company via
facsimile (the "Void Optional Prepayment Notice"). Upon the Company's receipt of
                -------------------------------
such Void Optional Prepayment Notice(s) and prior to payment of the full
Prepayment Price to Payee, (i) the Notice(s) of Prepayment at Option of Payee
shall be null and void with respect to this Note submitted for prepayment and
for which the Prepayment Price has not been paid and (ii) the Company shall
immediately return this Note submitted to the Company by the Payee for
prepayment under this Section 5(c) and for which the Prepayment Price has not
been paid. A Payee's delivery of a Void Optional Prepayment Notice and exercise
of its rights following such notice shall not affect the Company's obligations
to make any payments which have accrued prior to the date of such notice.

               (d)  Company's Prepayment Option. The Company may prepay, at the
                    ---------------------------
option of its Board of Directors, all or any portion of the outstanding
principal amount of this Note and the accrued and unpaid interest thereon upon
five (5) business days prior written notice to the Payee (the "Company
                                                               -------
Prepayment Notice") at a cash price equal to sum of the outstanding principal
-----------------
amount and any interest accrued and outstanding (the "Company Prepayment
                                                      ------------------
Price"). The Company may not deliver a Company Prepayment Notice to the Payee
-----
unless the Company has clear and good funds for a minimum of the amount it
intends to prepay in a bank account controlled by the Company. The Company
Prepayment Notice shall state the date of prepayment (the "Company Prepayment
                                                           ------------------
Date"), the Company Prepayment Price, the amount of the Note of such Payee to be
----
prepaid, the amount of accrued and unpaid interest through the Company
Prepayment Date and shall call upon the Payee to surrender to the Company on the
Company Prepayment Date at the place designated in the Company Prepayment Notice
such Payee's Note. The Company Prepayment Date shall be no more than five (5)
trading days after the date on which the Payee is notified of the Company's
intent to prepay the Note (the "Company Prepayment Notice Date"). If the Company
                                ------------------------------
fails to pay the Company Prepayment Price by the sixth (6/th/) trading day
following the Company Prepayment Notice Date, the prepayment will be declared
null and void and the Company shall lose its right to deliver a Company
Prepayment Notice to the Payee in the future. On or after the Company Prepayment
Date, the Payee shall surrender the Notes called for prepayment to the Company
at the place designated in the Company Prepayment Notice and shall thereupon be
entitled to receive payment of the Company Prepayment Price.

accordance with the internal laws of the State of New York, without giving
effect to the choice of law provisions. This Note shall not be interpreted or
construed with any presumption against the party causing this Note to be
drafted.

               --------
herein for purposes of convenience of reference only and shall not constitute a
part of this Note for any other purpose.

          13.  Remedies, Characterizations, Other Obligations, Breaches and
               ------------------------------------------------------------
Injunctive Relief. The remedies provided in this Note shall be cumulative and in
-----------------
addition to all other remedies available under this Note, at law or in equity
(including, without limitation, a decree of specific performance and/or other
injunctive relief), no remedy contained herein shall be deemed a waiver of
compliance with the provisions giving rise to such remedy and nothing herein
shall limit a Payee's right to pursue actual damages for any failure by the
Company to comply with the terms of this Note. Amounts set forth or provided for
herein with respect to payments and the like (and the computation thereof) shall

except as expressly provided herein, be subject to any other obligation of the
Company (or the performance thereof). The Company acknowledges that a breach by
it of its obligations hereunder will cause irreparable and material harm to the
Payee and that the remedy at law for any such breach may be inadequate.
Therefore the Company agrees that, in the event of any such breach or threatened
breach, the Payee shall be entitled, in addition to all other available rights
and remedies, at law or in equity, to seek and obtain such equitable relief,
including but not limited to an injunction restraining any such breach or
threatened breach, without the necessity of showing economic loss and without
any bond or other security being required.

          14.  Failure or Indulgence Not Waiver. No failure or delay on the part
               --------------------------------
of the Payee in the exercise of any power, right or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such power, right or privilege preclude other or further exercise thereof or of
any other right, power or privilege.

          15.  Enforcement Expenses. The Company agrees to pay all costs and
               ---------------------
expenses of enforcement of this Note, including, without limitation, reasonable
attorneys' fees and expenses.

          16.  Binding Effect. The obligations of the Company and the Payee set
               ---------------
forth herein shall be binding upon the successors and assigns of each such
party, whether or not such successors or assigns are permitted by the terms
hereof.

          17.  Compliance with Securities Laws. The Payee of this Note
               -------------------------------
acknowledges that this Note is being acquired solely for the Payee's own account
and not as a nominee for any other party, and for investment, and that the Payee
shall not offer, sell or otherwise dispose of this Note other than in compliance
with the laws of the United States of America and as guided by the rules of the
Securities and Exchange Commission. This Note and any Note issued in
substitution or replacement therefore shall be stamped or imprinted with a
legend in substantially the following form:

          ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES
          LAWS IS NOT REQUIRED."

          18.  Severability. The provisions of this Note are severable, and if
               ------------
any provision shall be held invalid or unenforceable in whole or in part in any
jurisdiction, then such

                                       9
<PAGE>

invalidity or unenforceability shall not in any manner affect such provision in
any other jurisdiction or any other provision of this Note in any jurisdiction.

          19.  Consent to Jurisdiction. Each of the Company and the Payee (i)
               -----------------------
hereby irrevocably submits to the jurisdiction of the United States District
Court sitting in the Southern District of New York and the courts of the State
of New York located in New York county for the purposes of any suit, action or
proceeding arising out of or relating to this Note and (ii) hereby waives, and
agrees not to assert in any such suit, action or proceeding, any claim that it
is not personally subject to the jurisdiction of such court, that the suit,
action or proceeding is brought in an inconvenient forum or that the venue of
the suit, action or proceeding is improper. Each of the Company and the Payee
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 the Purchase Agreement and agrees that such service shall constitute good
and sufficient service of process and notice thereof. Nothing in this Section 19
shall affect or limit any right to serve process in any other manner permitted

the obligations evidenced by this Note, hereby waive presentment, demand, notice
of nonpayment, protest and all other demands and notices in connection with the
delivery, acceptance, performance and enforcement of this Note, and do hereby
consent to any number of renewals of extensions of the time or payment hereof
and agree that any such renewals or extensions may be made without notice to any
such persons and without affecting their liability herein and do further consent
to the release of any person liable hereon, all without affecting the liability
of the other persons, firms or Company liable for the payment of this Note, AND
DO HEREBY WAIVE TRIAL BY JURY.

               (a)  No delay or omission on the part of the Payee in exercising
its rights under this Note, or course of conduct relating hereto, shall operate
as a waiver of such rights or any other right of the Payee, nor shall any waiver
by the Payee of any such right or rights on any one occasion be deemed a waiver
of the same right or rights on any future occasion.

               (b)  THE COMPANY ACKNOWLEDGES THAT THE TRANSACTION OF WHICH THIS
NOTE IS A PART IS A COMMERCIAL TRANSACTION, AND TO THE EXTENT ALLOWED BY
APPLICABLE LAW, HEREBY WAIVES ITS RIGHT TO NOTICE AND HEARING WITH RESPECT TO
ANY PREJUDGMENT REMEDY WHICH THE PAYEE OR ITS SUCCESSORS OR ASSIGNS MAY DESIRE
TO USE.
