     Each Purchaser severally and not jointly represents and warrants to the
Company as set forth in this Article II. None of the Purchasers makes any other
representations or warranties, express or implied, to the Company in connection
with the transactions contemplated hereby or

                                       2
<PAGE>

by any other Investment Agreements and any and all prior representations and
warranties, if any, which may have been made by such Purchaser to the Company in
connection with the transactions contemplated hereby shall be deemed to have
been merged in this Agreement and any such prior representations and warranties,
if any, shall not survive the execution and delivery of this Agreement.

     2.1  Investment Purpose. Purchaser is purchasing the Preferred Stock and
          ------------------
the Warrant for Purchaser's own account for investment only and not with a view
toward or in connection with the public sale or distribution thereof, and
Purchaser has no present intention of selling, granting any participation in or
otherwise distributing the same. Purchaser is entering into this Agreement to
purchase the Preferred Stock and the Warrant on its own behalf and is not
relying on any other investor in making its investment decision. By executing
this Agreement, Purchaser further represents that Purchaser does not have any
contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person, with
respect to the Preferred Stock and the Warrant. Purchaser will not resell the
Preferred Stock, the Warrant or any securities which may be issued upon
conversion thereof except pursuant to sales that are exempt from the
registration requirements of the Securities Act and/or sales registered under
the Securities Act. Purchaser understands that Purchaser must bear the economic
risk of this investment indefinitely, unless the Securities are registered
pursuant to the Securities Act and any applicable state securities laws or an
exemption from such registration is available, and that the Company has no
present intention of registering any such Securities other than as contemplated
by the Registration Rights Agreement. By making the representations in this
Section 2.1, Purchaser does not agree to hold the Securities for any minimum or
other specific term and reserves the right to dispose of the Securities at any
time in accordance with or pursuant to a registration statement or an exemption
from registration under the Securities Act.

     2.2  Accredited Investor Status. Purchaser is an "accredited investor" as
          --------------------------
that term is defined in Rule 501(a) of Regulation D.

     2.3  Reliance on Exemptions. Purchaser understands that the Securities are
          ----------------------
being offered and sold to Purchaser in reliance upon specific exemptions from
the registration requirements of the United States federal and state securities
laws and that the Company is relying upon the truth and accuracy of, and
Purchaser's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of Purchaser set forth herein in order to
determine the availability of such exemptions and the eligibility of Purchaser
to acquire the Securities.

     2.4  Information. Purchaser and its counsel have been furnished all
          -----------
materials relating to the business, finances and operations of the Company and
materials relating to the offer and sale of the Preferred Stock which have been
specifically requested by Purchaser which is all the information Purchaser
considers necessary or appropriate for deciding to purchase the Securities.
Purchaser has been afforded the opportunity to ask questions of the Company and
has received what Purchaser believes to be complete and satisfactory answers to
any such inquiries. Neither such inquiries nor any other due diligence
investigation conducted by Purchaser or any of its representatives shall modify,
amend or affect Purchaser's right to rely on the Company's

                                       3
<PAGE>

representations and warranties contained in Article III hereof. Purchaser
understands that Purchaser's investment in the Securities involves a high degree
of risk.

     2.5  Governmental Review. Purchaser 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 or an
investment therein.

     2.6  Transfer or Resale. Purchaser understands that (i) except as provided
          ------------------
in the Registration Rights Agreement, the Securities have not been and will not
be registered under the Securities Act or any state securities laws, and may not
be transferred unless subsequently registered thereunder or an exemption from
such registration is available (which exemption the Company expressly agrees may
be established as contemplated in clauses (b) and (c) of Section 5.1 hereof);
(ii) any sale of such Securities made in reliance on Rule 144 under the
Securities Act (or a successor rule) ("Rule 144") may be made only in accordance
                                       --------
with the terms of said Rule and further, if said Rule is not applicable, any
resale of such Securities without registration under the Securities Act under
circumstances in which the seller may be deemed to be an underwriter (as that
term is defined in the Securities Act) may require compliance with some other
exemption under the Securities 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 Securities 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 this Agreement or the
Registration Rights Agreement).

     2.7  Legends. Purchaser understands that, subject to Article V hereof, the
          -------
certificates for the Preferred Stock and the Warrant, and until such time as the
Conversion Shares and Warrant Shares have been registered under the Securities
Act as contemplated by the Registration Rights Agreement or otherwise may be

therein, being referred to herein as the "SEC Documents" and all the SEC
                                          -------------
documents filed prior to the date of this Agreement, the "Filed SEC Documents").
                                                          -------------------
The Company has made available (which may include access to the SEC's website)
to Purchaser true and complete copies of the SEC Documents, except for exhibits,
schedules and incorporated documents.  As of their respective dates, the SEC
Documents complied in all material respects with the requirements of the
Exchange Act and the rules and regulations of the SEC promulgated thereunder
applicable to the SEC Documents, and none of the SEC Documents, at the time they
were filed with the SEC, contained any untrue statement of a material fact or
omitted 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, except to the extent corrected by a subsequent
Filed SEC Document.  None of the statements made in any such SEC Documents is
currently required to be updated or amended under applicable law (except for
such statements as have been amended or updated by subsequent Filed SEC
Documents prior to the date of this Agreement).  The financial statements of the
Company included in the SEC Documents have been prepared in accordance with U.S.
generally accepted accounting principles, consistently applied, and the rules
and regulations of the SEC 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 do not include
footnotes or are condensed or summary statements) and fairly present in all
material respects the consolidated financial position of the Company and its
consolidated subsidiaries as of the dates thereof and the consolidated results
of their operations and cash flows for the periods then ended (subject, in the
case of unaudited statements, to normal, immaterial year-end audit adjustments).
Except as set forth in the Filed SEC Documents, the Company has no liabilities,
contingent or otherwise, other than (i) liabilities incurred subsequent to the
date of such financial statements in the ordinary course of business consistent
with past practice and (ii) obligations under contracts and commitments incurred
in the ordinary course of business and not required under U.S. generally
accepted accounting principles to be reflected in such financial statements, in
each case of clause (i) and (ii) next above which, individually or in the
aggregate, are not material to the financial condition, business, operations,
properties, operating results or prospects of the Company and its subsidiaries
taken on a whole.  The Filed SEC Documents contain or incorporate by reference a

                                       8
<PAGE>

complete and accurate list of all material undischarged written or oral
contracts, agreements, leases or other instruments to which the Company or any
subsidiary is a party or by which the Company or any subsidiary is bound or to
which any of the properties or assets of the Company or any subsidiary is
subject (each a "Contract").  None of the Company, its subsidiaries or, to the
                 --------
best knowledge of the Company, any of the other parties thereto, is in breach or
violation of any Contract, which breach or violation would have a Material
Adverse Effect.  No event, occurrence or condition exists which, with the lapse
of time, the giving of notice, or both, or the happening of any further event or
condition, would become a breach or default by the Company or its subsidiaries
under any Contract which breach or default would have a Material Adverse Effect.

     3.7  Absence of Certain Changes. Since December 31, 2000, there has been no
          --------------------------
Material Adverse Effect and no material adverse development in the business,
properties, operations, financial condition or results of operations of the
Company or any of its subsidiaries, except as disclosed in Schedule 3.7.
                                                           ------------

     3.8  Absence of Litigation.  Except as disclosed in Schedule 3.8, there is
          ---------------------                          ------------
no action, suit, proceeding, or to the knowledge of the Company or any of its
subsidiaries, inquiry or investigation before or by any court, public board,
governmental agency or authority, or self-regulatory organization or body
pending or, to the knowledge of the Company or any of its subsidiaries,
threatened against or affecting the Company, any of its subsidiaries, or any of
their respective directors or officers in their capacities as such, wherein an
unfavorable decision, ruling or finding would have a Material Adverse Effect or
would adversely affect the transactions contemplated by this Agreement or any of
the other Investment Agreements or which would adversely affect the validity or
enforceability of, or the authority or ability of the Company to perform its
obligations under, this Agreement or any of such other Investment Agreements.
The Company and each of its subsidiaries are unaware of any facts which could
give rise to a claim or proceeding which, if asserted or conducted with results
unfavorable to the Company or any of its subsidiaries, could have a Material
Adverse Effect.

     3.9  Disclosure.  No information relating to or concerning the Company set
          ----------
forth in this Agreement or provided to Purchaser in connection with the
transactions contemplated hereby contains an untrue statement of a material fact
or omits to state a material fact necessary in order to make the statements made
herein or therein, in light of the circumstances under which they were made, not
misleading.  Except for the execution and performance of this Agreement and the
other Investment Agreements, no material fact (within the meaning of the federal
securities laws of the United States) exists with respect to the Company or any
of its subsidiaries which has not been publicly disclosed.  The Company shall in
no event be deemed to have made to Purchaser any representations or warranties
with respect to any projections, estimates or budgets of future revenues,
expenses or expenditures, or future results of operations, which the Company
shall have supplied in good faith, except that with respect to projections
contained in the investment materials provided to Purchaser in March 2001, the
Company represents that such projections were prepared in good faith and that
the Company believes there is a reasonable basis for such projections.  Except
as disclosed in Schedule 3.9, the Company has not provided any material non-
                ------------
public information to Purchaser.

     3.10 Acknowledgment Regarding Purchaser's Purchase of the Securities.  The
          ---------------------------------------------------------------
Company acknowledges and agrees that Purchaser is not acting as a financial
advisor or

<PAGE>

fiduciary of the Company (or in any similar capacity) with respect to this
Agreement or the transactions contemplated hereby, that this Agreement and the
transactions contemplated hereby, and the relationship between Purchaser and the
Company, are "arms-length", and that any statement made by Purchaser, or any of
its representatives or agents, in connection with this Agreement or the
transactions contemplated hereby is not advice or a recommendation, is merely
incidental to Purchaser's purchase of the Securities and has not been relied
upon in any way by the Company, its officers, directors or other
representatives. The Company further represents to Purchaser that the Company's
decision to enter into this Agreement and the transactions contemplated hereby
has been based solely on an independent evaluation by the Company and its
representatives.

     3.11 Current Public Information.  Except as disclosed on Schedule 3.11, the
          --------------------------                          -------------
Company is currently eligible to register the resale of the Conversion Shares
and Warrant Shares on a registration statement on Form S-3 under the Securities
Act.

     3.12 No General Solicitation.  Neither the Company nor any person acting on

behalf of the Company has conducted any "general solicitation," as described in

offered hereby.

     3.13 No Integrated Offering.  Neither the Company, nor any of its
          ----------------------
affiliates, nor any person acting on its or their behalf, has directly or
indirectly made any offers or sales of any security or solicited any offers to
buy any security under circumstances that would prevent the parties hereto from
consummating the transactions contemplated hereby pursuant to an exemption from
registration under the Securities Act pursuant to the provisions of Section 4(2)
or Regulation D promulgated thereunder.  The transactions contemplated hereby
are exempt from the registration requirements of the Securities Act, assuming
the accuracy of the representations and warranties herein contained of Purchaser
to the extent relevant for such determination.

     3.14 No Brokers.  The Company has taken no action which would give rise to
          ----------
any claim by any person for brokerage commissions, finder's fees or similar
payments relating to this Agreement or the transactions contemplated hereby,
except for dealings with H.C. Wainwright & Co., Inc. and its selected dealers.

     3.15 Acknowledgment of Dilution. The Company acknowledges that its
          --------------------------
obligation to issue Conversion Shares upon conversion of the Preferred Stock is
binding upon it and enforceable regardless of the dilution that such issuance
may have on the ownership interests of other stockholders.

     3.16 Intellectual Property.  Except as disclosed in Schedule 3.16, each of
          ---------------------                          -------------
the Company and its subsidiaries owns or possesses adequate and enforceable
rights to use all patents, patent applications, trademarks, trademark
applications, trade names, service marks, copyrights, copyright applications,
licenses, know-how (including trade secrets and other unpatented and/or
unpatentable proprietary or confidential information, systems or procedures) and
other similar rights and proprietary knowledge (collectively, "Intangibles")
                                                               -----------
used or necessary for the conduct of its business as now being conducted and as
previously described in the Company's Annual Report on Form 10-K for its most
recently ended fiscal year for which an Annual Report on

                                       10
<PAGE>

Form 10-K was filed. To the knowledge of the Company and its subsidiaries,
neither the Company nor any subsidiary of the Company infringes on or is in
conflict with any right of any other person with respect to any Intangibles nor
is there any claim of infringement made by a third party against or involving
the Company or any of its subsidiaries, which infringement, conflict or claim,
individually or in the aggregate, if the subject of an unfavorable decision,
ruling or finding, would have a Material Adverse Effect.

     3.17 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, as amended; or made any bribe, rebate, payoff, influence payment, kickback
or other unlawful payment to any foreign or domestic government official or
employee.  Without limiting the generality of the foregoing, the Company and its
subsidiaries have not directly or indirectly made or agreed to make (whether or
not said payment is lawful) any payment to obtain, or with respect to, sales
other than usual and regular compensation to its or their employees and sales
representatives with respect to such sales.

     3.18 Key Employees; Company's Knowledge.  No Key Employee, to the best of
          ----------------------------------
the knowledge of the Company and its subsidiaries, is, or is now expected to be,
in violation of any material term of any employment contract, confidentiality,
disclosure or proprietary information agreement, non-competition agreement, or
any other contract or agreement or any restrictive covenant, and the continued
employment of each Key Employee does not subject the Company or any of its
subsidiaries to any liability with respect to any of the foregoing matters.
Except as disclosed in Schedule 3.18, no Key Employee has, to the best of the
                       -------------
knowledge of the Company and its subsidiaries, any intention to terminate or
limit his employment with, or services to, the Company or any of its
subsidiaries, nor is any such Key Employee subject to any constraints (e.g.,
litigation) which would cause such employee to be unable to devote his full time
and attention to such employment or services.   For purposes hereof, the term
"knowledge of the Company" shall mean the knowledge of each of the Key
Employees.

the Securities to the Purchasers in accordance with applicable securities laws
of the states of the United States, and shall provide evidence of any such
action so taken to the Purchasers on or prior to the date of the Closing.
Without limiting any of the Company's obligations under this Agreement, the
Registration Rights Agreement, the Warrant or the Certificate of Designation,
from and after the date of the

                                       11
<PAGE>

Closing, neither the Company nor any person acting on its behalf shall take any
action which would adversely affect any exemptions from registration under the
Securities Act with respect to the transactions contemplated hereby.

          ----------------
Securities, the Company shall timely file all reports required to be filed with
the SEC pursuant to the Exchange Act, and the Company shall not terminate its
status as an issuer required to file reports under the Exchange Act even if the
Exchange Act or the rules and regulations thereunder would permit such
termination.

     4.4  Use of Proceeds.  The Company shall use the proceeds from the sale of
          ---------------
the Securities for working capital only, in the ordinary course of its business,
and, without limiting the generality of the foregoing, shall not use such
proceeds to make a loan to any employee, officer, director or stockholder of the
Company, to repay any loan or other obligation of the Company (except for (i)
mandatory prepayment of the RMS Note (as defined below) with 50% of the proceeds
from the exercise of the Warrants and (ii) the repayment of monies loaned to the

date of the Closing and ending on the date which is one hundred and eighty (180)
days following the effective date of the Registration Statement, the Company
shall not issue or agree to issue any privately placed discounted, variable
priced equity or equity-like securities (including debt securities with equity
features), other than (i) to the Purchasers pursuant to this Agreement, (ii)
pursuant to a bona fide business acquisition of or by the Company, whether by
merger, joint venture, consolidation, sale of assets, sale or exchange of stock
or otherwise that has been approved by the Board of Directors of the Company,

would otherwise be true, the Company shall not indirectly accomplish any action
which the immediately preceding sentence would have otherwise prohibited from
being effected directly (e.g., by an asset drop-down to a subsidiary followed by
the offering of securities of such subsidiary).

and Warrant Shares on such exchange, and comply in all respects with the
Company's reporting, filing and other obligations under the bylaws or rules of

          -------------------------------
Securities Act may require delivery of a prospectus relating to the Common Stock
in connection with any sale thereof pursuant to a registration statement under
the Securities Act covering the resale by Purchaser of the Common Stock being
sold, and Purchaser shall use its reasonable efforts to comply with the
applicable prospectus delivery requirements of the Securities Act in connection
with any such sale.

     4.10 Intentional Acts or Omissions.  The Company shall not intentionally
          -----------------------------

which, if omitted to be performed, would prevent or excuse the performance of
this Agreement or any of the other Investment Agreements or any of the
transactions contemplated hereby or thereby or the benefits intended to be
secured thereby by Purchaser (including, without limitation, pursuant to any
agreements or documents obtained by the Company as a condition to any Closing
hereunder).

     4.11 Corporate Existence.  So long as a Purchaser beneficially owns any
          -------------------
Securities, the Company shall maintain its corporate existence, except in the
event of a merger or consolidation as long as the surviving or successor entity
in such transaction (i) assumes the Company's obligations hereunder and under
the agreements and instruments entered into in connection herewith regardless of
whether or not the Company would have had a sufficient number of shares of
Common Stock authorized and available for issuance in order to effect the
conversion of all Preferred Stock and the exercise of the Warrant outstanding as
of the date of such transaction (including, without limitation, without giving
effect to any limitations on conversion or exercise thereof) and (ii) is a

                                                      --------------------
Date").  For purposes hereof, "Stockholder Approval" means (a) authorization by

the required vote under Nasdaq Rule 4350 of the stockholders of the Company of
the issuance of shares of Common Stock upon conversion of shares of Preferred
Stock pursuant to the terms of the Certificate of Designation and the exercise
of the Warrant pursuant to the terms thereof in the aggregate in excess of
19.99% of the outstanding shares of Common Stock, (b) if necessary and to the

the Company and each of its subsidiaries will not enter into any agreement or
arrangement, written or oral, directly or indirectly, with an affiliate or

distribute monies, goods or other valuable consideration to, an affiliate,
except upon fair and reasonable terms under the circumstances as determined by
the Company in good faith, taking into account all of the facts and
circumstances of such agreement or arrangement, and except for existing
intercompany debt or transactions with or between the Company and any of its
wholly-owned subsidiaries and payments and benefits to officers and directors in
their capacities as such in the ordinary course of business, consistent with
past practices.

     4.14 Limitation of Agreements.  The Company will not, and will not permit
          ------------------------
any subsidiary to, enter into any Contract, or any amendment, modification,
extension or supplement to any existing Contract, which limits the Company from
performing its obligations under any of the Investment Agreements or that would
limit the number of shares of Common Stock issuable to a Purchaser upon
conversion of the Preferred Stock or exercise of the Warrant without Stockholder
Approval, including, without limitation, by integration of other shares of
Common Stock with the Cap Amount.

     4.15 Reverse Stock Split.  The Company covenants and agrees that it will
          -------------------
use its best efforts to obtain by July 31, 2001 stockholder approval to conduct
a 1 to 5 reverse stock split of its Common Stock, or such greater ratio (e.g. 1
to 6) as necessary to comply with the Nasdaq Marketplace Rules (the "Reverse
                                                                     -------
Stock Split"), provided that the number of shares of Common Stock reduced to one
-----------
(1) share of Common Stock in the Reverse Stock Split multiplied by the closing
price of the Common Stock on the record date set for the Company's next
stockholder meeting ("Closing Price") shall equal or exceed $2.00 per share.
For example, if the Company conducts a 1 to 6 reverse stock split, the Closing
Price multiplied by 6 must be greater than or equal to $2.00 per share.

          -------------------------

the conversion of the $1.7 million promissory note issued to Jotter

                     ------
transaction between the Company and Jotter ("Jotter Asset Purchase") into shares
                                             ---------------------

stockholder approval is required for such conversion, and the Company shall, in
any event, provide evidence satisfactory to the Purchaser of such conversion.

                  LEGEND REMOVAL, TRANSFER, AND CERTAIN SALES

     5.1  Removal of Legend.  The Legend shall be removed and the Company shall
          -----------------
issue a certificate without any legend to the holder of any Security upon which
such Legend is stamped, and a certificate for a Security shall be originally
issued without any legend, if, unless otherwise required by applicable state
securities laws, (a) the sale thereof is registered under the Securities Act
pursuant to an effective registration statement, (b) such holder provides the
Company with an opinion of counsel, in form, substance and scope customary for
opinions of counsel in comparable transactions and reasonably acceptable to the
Company (the reasonable cost of which shall be borne by the Company), to the
effect that a public sale or transfer of such Security may be made without
registration under the Securities Act or (c) Purchaser provides reasonable
assurances that such Security can be sold pursuant to Rule 144.  Each Purchaser
agrees to sell all Securities, including those represented by a certificate(s)
from which the Legend has been removed, or which were originally issued without
the Legend, pursuant to an effective registration statement and to deliver a
prospectus in connection with such sale or in compliance with an exemption from
the registration requirements of the Securities Act.  In the event the Legend is
removed from any Security or any Security is issued without the Legend and
thereafter the effectiveness of a registration statement covering the resale of
such Security is suspended or the Company determines that a supplement or
amendment thereto is required by applicable securities laws, then upon
reasonable advance notice to the Purchaser holding such Security, the Company
may require that the Legend be placed on any such Security that cannot then be
sold pursuant to an effective registration statement or Rule 144 or with respect
to which the opinion referred to in clause (b) next above has not been rendered,
which Legend shall be removed when such Security may be sold pursuant to an
effective registration statement or Rule 144 or such holder provides the opinion
with respect thereto described in clause (b) next above.

     5.2  Transfer Agent Instructions.  The Company shall instruct its transfer
          ---------------------------
agent to issue certificates, registered in the name of each Purchaser or its
nominee, for the Conversion Shares and/or Warrant Shares in such amounts as
specified from time to time by Purchaser to the Company upon, and in accordance
with, the conversion of the Preferred Stock and the exercise of the Warrant.
Such certificates shall bear a legend only in the form of the Legend and only to
the extent permitted by Section 5.1 above.  The Company warrants that no
instruction other than such instructions referred to in this Article V, and no
stop transfer instructions other than stop transfer instructions to give effect
to Section 2.6 hereof in the case of the Conversion Shares and/or Warrant Shares
prior to registration of the Conversion Shares and/or Warrant Shares under the
Securities Act, 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.  Nothing in this Section shall affect in any way Purchaser's
obligations and agreement set forth in Section 5.1 hereof to resell the
Securities pursuant to an effective registration statement and to deliver a
prospectus in connection with such sale or in compliance with an exemption from
the registration requirements of applicable securities laws.  Without limiting
the foregoing, if (a) Purchaser provides the Company with an opinion of counsel,
which opinion of counsel shall be in form, substance and scope customary for
opinions of counsel in comparable transactions and reasonably acceptable to the
Company (the reasonable cost of which shall be borne by the Company), to the
effect that the Securities to be sold or transferred may be sold or transferred

                                       15
<PAGE>

pursuant to an exemption from registration or (b) Purchaser transfers Securities
to an affiliate or pursuant to Rule 144, the Company shall permit the transfer,
and, in the case of the Conversion Shares and/or Warrant Shares, promptly
instruct its transfer agent to issue one or more certificates in such name and
in such denomination as specified by Purchaser in order to effect such a
transfer or sale.  The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to Purchaser 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 Article V will be inadequate and agrees, in the event of a breach or
threatened breach by the Company of the provisions of this Article V, that
Purchaser shall be entitled, in addition to all other available remedies, to an
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.

          ---------------------------------
to be elected by the holders of the Preferred Stock (the "Series E Directors"),
each holder of the Preferred Stock shall vote at any regular or special meeting
of stockholders or execute a written consent at the request of Palo Alto
Investors of such number of shares of voting securities then held by such holder
(or as to which it then has voting power) as may be necessary to elect two (2)
directors nominated by Palo Alto Investors. Each holder of Preferred Stock
hereby irrevocably constitutes and appoints Palo Alto Investors as its true and
lawful attorney-in-fact, in its name, place, and stead, to make, execute,
acknowledge, and file written consents in connection with the election or
removal of directors of the Company. It is expressly intended by each holder of
the Preferred Stock that the power of attorney granted hereby is coupled with an
interest, shall be irrevocable unless and until the covenants of this Section
8.1 terminate pursuant to the terms hereof, and shall survive and not be
affected by the subsequent disability or incapacity of such holder of Preferred
Stock (or if such holder of Preferred Stock is a corporation, partnership,
trust, association, limited liability company or other legal entity, by the
dissolution or termination thereof). In addition, each holder of the Preferred
Stock hereby constitutes and appoints Palo Alto Investors, with full power of
substitution, as the proxy of such holder and hereby authorizes it to represent
and to vote, or to execute and deliver written consents or otherwise act with
respect to, all of the Preferred Stock now owned or hereafter acquired by such
holder on all matters in connection with the election and removal of directors
of the Company, to the same extent and with the same effect as such holder might
or could do under applicable law, rules and regulations. The proxy granted
pursuant to the immediately preceding sentence is given in consideration of the
agreements and covenants of the Company and shareholders of the

                                       18
<PAGE>

Company pursuant to this Agreement and as such is coupled with an interest and
shall be irrevocable unless and until the covenants of this Section terminate
pursuant to the terms hereof. Each holder of Preferred Stock hereby revokes any
and all previous proxies granted with respect to any of the Preferred Stock
owned by such holder and shall not hereafter, unless and until this Agreement
terminates, purport to grant any other proxy or power of attorney with respect
to any of the Preferred Stock owned by such holder, deposit any of the Preferred
Stock into a voting trust or enter into any agreement (other than this
Agreement), arrangement or understanding with any person, directly or
indirectly, to vote, grant any proxy or give instructions with respect to the
voting of any of the Preferred Stock owned by such holder. Each holder of
Preferred Stock and Conversion Shares shall: (i) vote at any regular or special
meeting of the stockholders for the removal of a Series E Director if, and only
if, Palo Alto Investors designates that such director be removed; and (ii)
execute a written consent for the removal of a Series E Director if, and only
if, Palo Alto Investors designates that such director be removed. Except as
provided in the preceding sentence, no holder of Preferred Stock or Conversion
Shares shall vote for, or execute a written consent resulting in, the removal of
a Series E Director.

     8.2  Manner of Voting. The voting of shares pursuant to this Agreement may
          ----------------
be effected in person, by proxy, by written consent, or in any other manner
permitted by applicable law.

     8.3  Palo Alto Investors' Legal Fees. After Closing, the Company shall
          -------------------------------
reimburse Palo Alto Investors for up to $20,000 in attorneys' fees, costs and
disbursements related to the Series E Preferred Stock and Warrant financing.

agrees that service of process upon the Company mailed by the first class mail

     9.9  Survival. The representations and warranties of Purchaser and the
          --------
Company shall survive the Closing hereunder for a period of two (2) years after
the date of the Closing and the covenants of the parties shall survive the

by or on behalf of Purchaser. The Company agrees to indemnify (which indemnity
shall include advancement of expenses as they are incurred) and hold harmless
each of the Purchasers and each of Purchaser's officers, directors, employees,
partners, agents and affiliates for loss or damage or expenses (including
reasonable attorneys fees) arising as a result of or related to (a) any breach
or alleged breach by the Company of any of its representations or covenants set
forth herein, (b) any cause of action, suit or claim brought or made against
Purchaser and arising out of or resulting from the execution, delivery,
performance or enforcement of the Investment Agreements or any other
certificate, instrument or document contemplated hereby or thereby, (c) any

Purchaser shall limit any remedy which would otherwise be available to Purchaser
at law or in equity. Nothing in this Agreement shall limit any rights Purchaser
may have with any applicable federal or state securities laws with respect to

the remedy at law for any such breach may be inadequate. The Company therefore
agrees that, in the event of any such breach or threatened breach, Purchaser
shall be entitled, in addition to all other available remedies, to an injunction
restraining any breach, without the necessity of showing economic loss and
without any bond or other security being required.

a party in the exercise of any power, right or privilege hereunder shall operate
