                      III.  The Company's Representations

          The Company represents and warrants to Buyer that:

          A.  Capitalization.

              1.  The authorized capital stock of the Company consists of: (i)
     25,000,000 shares of Common Stock, of which 7,767,440 shares are issued and
     outstanding on the date hereof; and (ii) 5,000,000 shares of "blank check"
     preferred stock, of which no shares are issued and outstanding on the date
     hereof.  All of the issued and outstanding shares of Common Stock and
     preferred stock, if any, have been duly authorized and validly issued and
     are fully paid and nonassessable.  As of the date hereof, the Company has
     outstanding stock options and warrants to purchase 965,480 shares of Common
     Stock.  The Conversion Shares and Warrant Shares have been duly and validly
     authorized and reserved for issuance by the Company, and when issued by the
     Company upon conversion of, or in lieu of accrued dividends on, the
     Preferred Shares and on exercise of the Warrants will be duly and validly
     issued, fully paid and nonassessable and will not subject the holder
     thereof to personal liability by reason of being such holder.  There are no
     preemptive, subscription, "call" or

                                      -3-


     other similar rights to acquire the Common Stock (including the Conversion
     Shares and Warrant Shares) that have been issued or granted to any person,
     except as disclosed on Schedule III.A.1. hereto or otherwise previously
     disclosed in writing to Buyer.

              2.  Except as disclosed on Schedule III.A.2. hereto, the Company
     does not own or control, directly or indirectly, any interest in any other
     corporation, partnership, limited liability company, unincorporated
     business organization, association, trust or other business entity.

          B.  Organization; Reporting Company Status.

              1.  The Company is a corporation duly organized, validly existing
     and in good standing under the laws of the State of Delaware and is duly
     qualified as a foreign corporation in all jurisdictions in which the
     failure to so qualify would have a material adverse effect on the business,
     properties, prospects, condition (financial or otherwise) or results of
     operations of the Company or on the consummation of any of the transactions
     contemplated by this Agreement (a "Material Adverse Effect").

              2.  The Company has registered the Common Stock pursuant to
     Section 12 of the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), and has timely filed with the Commission all reports and
     information required to be filed by it pursuant to all reporting
     obligations under Section 13(a) or 15(d), as applicable, of the Exchange
     Act for the 12-month period immediately preceding the date hereof.  The
     Common Stock is listed and traded on the Nasdaq National Market ("Nasdaq")
     and the Company has not received any notice regarding, and to its knowledge
     there is no threat of, the termination or discontinuance of the eligibility
     of the Common Stock for such listing, except as disclosed on Schedule
     III.B.2.  As of December 15, 1999, the Company will be in compliance with
     Nasdaq listing requirements and will be listed and traded on either Nasdaq
     National Market or Nasdaq Small Cap Market.

          C.  Authorized Shares.  The Company has duly and validly authorized
and reserved for issuance [1,037,000] shares of Common Stock sufficient in
number for the conversion of the Preferred Shares and the exercise of the
Warrants.  The Company understands and acknowledges the potentially dilutive
effect to the Common Stock of the issuance of the Preferred Shares and Warrant
Shares upon conversion of the Preferred Shares and exercise of the Warrants,
respectively.  The Company further acknowledges that its obligation to issue
Conversion Shares upon conversion of the Preferred Shares and Warrant Shares
upon exercise of the Warrants in accordance with this Agreement, the Preferred
Shares and the Warrants is absolute and unconditional regardless of the dilutive
effect that such issuance may have on the ownership interests of other
stockholders of the Company and notwithstanding the commencement of any case
under 11 U.S.C. (S) 101 et seq. (the "Bankruptcy Code").  In the event the
Company is a debtor under the Bankruptcy Code, the Company hereby waives to the
fullest extent permitted any rights to relief it may have under 11 U.S.C. (S)
362 in respect of the conversion of the Preferred Shares and the exercise of the
Warrants.  The Company agrees, without cost or expense to Buyer, to take or
consent to any and all action necessary to effectuate relief under 11 U.S.C. (S)
362.  Schedule III. C. hereto sets forth (i) all issuances and sales by the
Company since December 31, 1998 of its capital stock, and other securities
convertible, exercisable or exchangeable for capital stock of the Company, (ii)

                                      -4-


the amount of such securities sold, including any underlying shares of capital
stock, (iii) the purchaser thereof, and (iv) the amount paid therefor.

          D.  Authority; Validity and Enforceability. The Company has the
requisite corporate power and authority to file and perform its obligations
under the Certificate of Designation and to enter into the Documents (as
hereinafter defined), and to perform all of its obligations hereunder and
thereunder (including the issuance, sale and delivery to Buyer of the
Securities). The execution, delivery and performance by the Company of the
Documents, and the consummation by the Company of the transactions contemplated
hereby and thereby (including, without limitation, the filing of the Certificate
of Designation with the Delaware Secretary of State's office, the issuance of
the Preferred Shares, the Warrants and the issuance and reservation for issuance
of the Conversion Shares and Warrant Shares), has been duly authorized by all
necessary corporate action on the part of the Company. Each of the Documents has
been duly and validly executed and delivered by the Company and the Certificate
of Designation has been duly filed with the Delaware Secretary of State's office
by the Company and each instrument constitutes a valid and binding obligation of
the Company enforceable against it in accordance with its terms, subject to
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and similar laws affecting creditors' rights and remedies generally
and except as rights to indemnity and contribution may be limited by federal or
state securities laws or the public policy underlying such laws. The Securities
have been duly and validly authorized for issuance by the Company and, when
executed and delivered by the Company, will be valid and binding obligations of
the Company enforceable against it in accordance with their terms, subject to
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and similar laws affecting creditors' rights and remedies generally.
For purposes of this Agreement, the term "Documents" means (i) this Agreement;
(ii) the Registration Rights Agreement of even date herewith between the Company
and Buyer, a copy of which is annexed hereto as Exhibit D (the "Registration
Rights Agreement"); (iii) the Certificate of Designation; (iv) the Warrants; and
(v) the Escrow Instructions.

          E.  Authorization of the Securities.  The authorization, issuance,
sale and delivery of the Preferred Shares and Warrants has been duly authorized
by all requisite corporate action on the part of the Company.  As of the Closing
Date, the Preferred Shares and the Warrants, and the Conversion Shares and the
Warrant Shares upon their issuance in accordance with the Certificate of
Designation and the Warrants, respectively, will be validly issued and
outstanding, fully paid and nonassessable, and not subject to any preemptive
rights, rights of first refusal or other similar rights.

          F.  Non-contravention.  The execution and delivery by the Company of
the Documents, the issuance of the Securities, and the consummation by the
Company of the other transactions contemplated hereby and thereby, including,
without limitation, the filing of the Certificate of Designation with the
Delaware Secretary of State's office, do not and will not conflict with or
result in a breach by the Company of any of the terms or provisions of, or
constitute a default (or an event which, with notice, lapse of time or both,
would constitute a default) under (i) the articles of incorporation or by-laws
of the Company or (ii) any indenture, mortgage, deed of trust or other material
agreement or instrument to which the Company is a party or by which its
properties or assets are bound, or any law, rule, regulation, decree, judgment
or order of any court or public or governmental authority having jurisdiction
over the Company or any of the Company's properties or

                                      -5-


assets, except as to clause (ii) above such conflict, breach or default which
would not have a Material Adverse Effect.

          G.  Approvals.  No authorization, approval or consent of any court or
public or governmental authority is required to be obtained by the Company for
the issuance and sale of the Preferred Shares or the Warrants (and the
Conversion Shares and Warrant Shares) to Buyer as contemplated by this
Agreement, except such authorizations, approvals and consents that have been
obtained by the Company prior to the date hereof.

          H.  Commission Filings.  None of the Company's reports and documents
heretofore filed with the Commission pursuant to the Securities Act or the
Exchange Act (collectively, the "Commission Filings") contained at the time they
were filed any untrue statement of a material fact or omitted to state any
material fact required to be stated therein or necessary to make the statements
made therein, in light of the circumstances under which they were made, not
misleading.

defined in Section III.M.), there has not occurred any change, event or
development in the business, financial condition, prospects or results of
operations of the Company, and there has not existed any condition, having or
reasonably likely to have a Material Adverse Effect.

          J.  Full Disclosure.  There is no fact known to the Company (other
than general economic or industry conditions known to the public generally) that
has not been fully disclosed in writing to the Buyer that (i) reasonably could
be expected to have a Material Adverse Effect or (ii) reasonably could be
expected to materially and adversely affect the ability of the Company to
perform its obligations pursuant to the Documents.

          K.  Absence of Litigation.  There is no action, suit, claim,
proceeding, inquiry or investigation pending or, to the Company's knowledge,
threatened, by or before any court or public or governmental authority which, if
determined adversely to the Company, would have a Material Adverse Effect.

          L.  Absence of Events of Default.  No "Event of Default" (as defined
in any agreement or instrument to which the Company is a party) and no event
which, with notice, lapse of time or both, would constitute an Event of Default
(as so defined), has occurred and is continuing, which could have a Material
Adverse Effect.

          M.  Financial Statements; No Undisclosed Liabilities.  The Company has
delivered to Buyer true and complete copies of its audited balance sheet as at

liabilities of any kind (whether accrued, absolute, contingent or otherwise, and
whether due or to become due) that would have been required to be reflected in,
reserved against or otherwise described in the Balance Sheet or in the notes
thereto in accordance with GAAP, which was not fully reflected in, reserved
against or otherwise described in the Balance Sheet or the notes thereto or was
not incurred in the ordinary course of business consistent with the Company's
past practices since the Balance Sheet Date.

          N.  Compliance with Laws; Permits.  The Company is in compliance with
all laws, rules, regulations, codes, ordinances and statutes (collectively,
"Laws") applicable to it or to the conduct of its business, except for such
noncompliance which would not have a Material Adverse Effect.  The Company
possesses all permits, approvals, authorizations, licenses, certificates and
consents from all public and governmental authorities which are necessary to
conduct its business, except for those the absence of which would not have a
Material Adverse Effect.

          O.  Related Party Transactions.  Except as set forth on Schedule III.
O. hereto, neither the Company nor any of its officers, directors or

          P.  Insurance.  The Company maintains property and casualty, general
liability, workers' compensation, environmental hazard, personal injury and
other similar types of insurance with financially sound and reputable insurers
that is adequate, consistent with industry standards and the Company's
historical claims experience.  The Company has not received notice from, and has
no knowledge of any threat by, any insurer (that has issued any insurance policy
to the Company) that such insurer intends to deny coverage under or cancel,
discontinue or not renew any insurance policy presently in force.

          Q.  Securities Law Matters.  Based, in part, upon the representations
and warranties of Buyer set forth in Section II hereof, the offer and sale by
the Company of the Securities is exempt from (i) the registration and prospectus

               T.  ERISA Matters.  The Company and its ERISA Affiliates are in
compliance in all material respects with all provisions of ERISA applicable to
it.  No Reportable Event has occurred, been waived or exists as to which the
Company or any ERISA Affiliate was required to file a report with the Pension
Benefits Guaranty Corporation, and the present value of all liabilities under
all Plans (based on those assumptions used to fund such Plans) did not, as of
the most recent annual valuation date applicable thereto, exceed the value of
the assets of all such Plans in the aggregate.  None of the Company or ERISA
Affiliates has incurred any Withdrawal Liability that

                                      -9-


could result in a Material Adverse Effect. None of the Company or ERISA
Affiliates has received any notification that any Multiemployer Plan is in
reorganization or has been terminated within the meaning of Title IV of ERISA,
and no Multiemployer Plan is reasonably expected to be in reorganization or
termination where such reorganization or termination has resulted or could
reasonably be expected to result in increases to the contributions required to
be made to such Plan or otherwise.

          For purposes of this Section III. T.:

          "ERISA" means the Employee Retirement Income Security Act of 1974, or
any successor statute, together with the regulations thereunder, as the same may
be amended from time to time.

          "ERISA Affiliate" means any trade or business (whether or not
incorporated) that was, is or hereafter may become, a member of a group of which
the Company is a member and which is treated as a single employer under Section
414 of the Internal Revenue Code of 1986, as amended (the "Internal Revenue
Code").

          "Multiemployer Plan" means a multiemployer plan as defined in Section
4001(a)(3) of ERISA to which the Company or any ERISA Affiliate (other than one
considered an ERISA Affiliate only pursuant to subsection (m) or (o) of Section
414 of the Internal Revenue Code) is making or accruing an obligation to make
contributions, or has within any of the preceding five plan years made or
accrued an obligation to make contributions.

          "PBGC" means the Pension Benefit Guaranty Corporation referred to and
defined in ERISA or any successor thereto.

          "Plan" means any pension plan (other than a Multiemployer Plan)
subject to the provision of Title IV of ERISA or Section 412 of the Internal
Revenue Code that is maintained for employees of the Company or any ERISA
Affiliate.

          "Reportable Event" means any reportable event as defined in Section
4043(b) of ERISA or the regulations issued thereunder with respect to a Plan
(other than a Plan maintained by an ERISA Affiliate that is considered an ERISA
Affiliate only pursuant to subsection (m) or (o) of Section 414 of the Internal
Revenue Code).

          "Withdrawal Liability" means liability to a Multiemployer Plan as a
result of a complete or partial withdrawal from such Multiemployer Plan, as such
terms are defined in Part I of Subtitle E of Title IV of ERISA.

          U.  Tax Matters.

              1.  The Company has filed all Tax Returns which it is required to
     file under applicable Laws, except for such Tax Returns in respect of which
     the failure to so file does not and could not have a Material Adverse
     Effect; all such Tax Returns are true and accurate in all material respects
     and have been prepared in compliance with all applicable Laws; the Company
     has paid all Taxes due and owing by it (whether or not such Taxes are
     required to be shown on a Tax Return) and have withheld and paid over to
     the appropriate

                                      -10-


     taxing authorities all Taxes which it is required to withhold from amounts
     paid or owing to any employee, stockholder, creditor or other third
     parties; and since the Balance Sheet Date, the charges, accruals and
     reserves for Taxes with respect to the Company (including any provisions
     for deferred income taxes) reflected on the books of the Company are
     adequate to cover any Tax liabilities of the Company if its current tax
     year were treated as ending on the date hereof.

               2.  No claim has been made by a taxing authority in a
     jurisdiction where the Company does not file tax returns that such
     corporation is or may be subject to taxation by that jurisdiction.  There
     are no foreign, federal, state or local tax audits or administrative or
     judicial proceedings pending or being conducted with respect to the
     Company; no information related to Tax matters has been requested by any
     foreign, federal, state or local taxing authority; and, except as disclosed
     above, no written notice indicating an intent to open an audit or other
     review has been received by the Company from any foreign, federal, state or
     local taxing authority.  There are no material unresolved questions or
     claims concerning the Company's Tax liability, except as disclosed on
     Schedule III. U. 2.  The Company (A) has not executed or entered into a
     closing agreement pursuant to Section 7121 of the Internal Revenue Code or
     any predecessor provision thereof or any similar provision of state, local
     or foreign law; or (B) has not agreed to or is required to make any
     adjustments pursuant to Section 481(a) of the Internal Revenue Code or any
     similar provision of state, local or foreign law by reason of a change in
     accounting method initiated by the Company or any of its subsidiaries or
     has any knowledge that the IRS has proposed any such adjustment or change
     in accounting method, or has any application pending with any taxing
     authority requesting permission for any changes in accounting methods that
     relate to the business or operations of the Company.  The Company has not
     been a United States real property holding corporation within the meaning
     of Section 897(c)(2) of the Internal Revenue Code during the applicable
     period specified in Section 897(c)(1)(A)(ii) of the Internal Revenue Code.

               3.  The Company has not made an election under Section 341(f) of
     the Internal Revenue Code.  The Company is not liable for the Taxes of
     another person that is not a subsidiary of the Company under (A) Treas.
     Reg. Section 1.1502-6 (or comparable provisions of state, local or foreign
     law), (B) as a transferee or successor, (C) by contract or indemnity or (D)
     otherwise.  The Company is not a party to any tax sharing agreement.  The
     Company has not made any payments, is obligated to make payments or is a
     party to an agreement that could obligate it to make any payments that
     would not be deductible under Section 280G of the Internal Revenue Code.

          For purposes of this Section III. U.:

          "IRS" means the United States Internal Revenue Service.

          "Tax" or "Taxes" means federal, state, county, local, foreign, or
other income, gross receipts, ad valorem, franchise, profits, sales or use,
transfer, registration, excise, utility, environmental, communications, real or
personal property, capital stock, license, payroll, wage or other withholding,
employment, social security, severance, stamp, occupation, alternative or add-on

                                      -11-


minimum, estimated and other taxes of any kind whatsoever (including, without
limitation, deficiencies, penalties, additions to tax, and interest attributable
thereto) whether disputed or not.

          "Tax Return" means any return, information report or filing with
respect to Taxes, including any schedules attached thereto and including any
amendment thereof.

          V.  Property.  The Company has good and marketable title to all real
and personal property owned by it, free and clear of all liens, encumbrances and
defects except such as are described on Schedule III. V. hereto or such as do
not materially affect the value of such property and do not interfere with the
use made and proposed to be made of such property by the Company; and any real
property and buildings held under lease by the Company are held by it under
valid, subsisting and enforceable leases with such exceptions as are not
material and do not interfere with the use made and proposed to be made of such
property and buildings by the Company.

          W.  Intellectual Property.  The Company 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") necessary for the conduct of its business as now being conducted
including, but not limited to, those described on Schedule III. W. hereto or
where the failure to own or possess such rights would not have a Material
Adverse Effect.  To the best of the Company's knowledge, after due inquiry, the
Company is not infringing upon or in conflict with any right of any other person
with respect to any Intangibles.  Except as disclosed on Schedule III. W.
hereto, no claims have been asserted by any person to the ownership or use of
any Intangibles and the Company has no knowledge of any basis for such claim.

          X.  Internal Controls and Procedures.  The Company maintains accurate
books and records and internal accounting controls which provide reasonable
assurance that (i) all transactions to which the Company is a party or by which
its properties are bound are executed with management's authorization; (ii) the
reported accountability of the Company's assets is compared with existing assets
at regular intervals; (iii) access to the Company's assets is permitted only in
accordance with management's authorization; and (iv) all transactions to which
the Company is a party or by which its properties are bound are recorded as
necessary to permit preparation of the financial statements of the Company in
accordance with GAAP.

          Y.  Payments and Contributions.  Neither the Company nor any of its
directors, officers or, to its knowledge, other employees has (i) used any
Company funds for any unlawful contribution, endorsement, gift, entertainment or
other unlawful expense relating to political activity; (ii) made any direct or
indirect unlawful payment of Company funds to any foreign or domestic government
official or employee, (iii) violated or is in violation of any provision of the
Foreign Corrupt Practices Act of 1977, as amended; or (iv) made any bribe,
rebate, payoff, influence payment, kickback or other similar payment to any
person with respect to Company matters.

          Z.  No Misrepresentation.  No representation or warranty of the
Company contained in this Agreement, any schedule, annex or exhibit hereto or
any agreement, instrument or certificate furnished by the Company to Buyer
pursuant to this Agreement, contains any untrue

                                      -12-


statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein, not misleading.

                  IV.  Certain Covenants and Acknowledgments

          A.  Restrictive Legend.  Buyer acknowledges and agrees that, upon
issuance pursuant to this Agreement, the Securities (and any shares of Common
Stock issued in conversion of the Preferred Shares or exercise of the Warrants)
shall have endorsed thereon a legend in substantially the following form (and a
stop-transfer order may be placed against transfer of the Preferred Shares, the
Warrant Shares and the Conversion Shares until such legend has been removed):

     "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
     1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY
     STATE, AND ARE BEING OFFERED AND SOLD PURSUANT TO AN EXEMPTION FROM THE
     REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH LAWS.  THESE
     SECURITIES MAY NOT BE SOLD OR TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE
     EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OR SUCH
     OTHER LAWS."

          B.  Filings.  The Company shall make all necessary Commission Filings
and  "blue sky" filings required to be made by the Company in connection with
the sale of the Securities to the Buyer as required by all applicable Laws, and
shall provide a copy thereof to the Buyer promptly after such filing.

          C.  Reporting Status.  So long as the Buyer beneficially owns any of
the Securities, the Company shall timely file all reports required to be filed
by it with the Commission pursuant to Section 13 or 15(d) of the Exchange Act.

          D.  Use of Proceeds.  The Company shall use the net proceeds from the
sale of the Securities (excluding amounts paid by the Company for Buyer's out-
of-pocket costs and expenses incurred in connection with the transactions
contemplated by this Agreement and finder's fees in connection with such sale)
solely for general corporate and working capital purposes.

          E.  Listing.  Except to the extent the Company lists its Common Stock
on The New York Stock Exchange, the Company shall use its best efforts to
maintain its listing of the Common Stock on Nasdaq.

          F.  Reserved Conversion Shares.  The Company at all times from and
after the date hereof shall have a sufficient number of shares of Common Stock
duly and validly authorized and reserved for issuance to satisfy the conversion,
in full, of the 2,000 Preferred Shares and upon the exercise of the Warrants.

          G.  Right of First Refusal.  If the Company should propose (the
"Proposal") to issue Common Stock or securities convertible into Common Stock at
a price less than the Current

                                      -13-


Market Price (as defined in Certificate of Designation), or debt at less
than par value or having an effective annual interest rate in excess of 9.9%
(each a "Right of First Refusal Security" and collectively, the "Right of First
Refusal Securities"), in each case on the date of issuance during the period
ending two years after the Closing Date (the "Right of First Refusal Period"),
the Company shall be obligated to offer the Buyer on the terms set forth in the
Proposal (the "Offer") and the Buyer shall have the right, but not the
obligation, to accept such Offer on such terms. If during the Right of First
Refusal Period, the Company provides written notice to the Buyer that it
proposes to issue any Right of First Refusal Securities on the terms set forth
in the Proposal, then the Buyer shall have 10 business days to accept or reject
such offer in writing. If the Company fails to: (i) issue a Proposal during the
Right of First Refusal Period, (ii) offer the Buyer the opportunity to complete
the transaction as set forth in the Proposal, or (iii) enter into an agreement
with the Buyer, at such terms after the Buyer has accepted the Offer, then the
Company shall pay to the Buyer, as liquidated damages, an amount in total equal
to 10% of the amount paid to the Company for the Right of First Refusal
Securities. The foregoing right of first refusal is and shall be senior in right
to any other right of first refusal issued by the Company to any other Person
(as defined in the Certificate of Designation). Notwithstanding the foregoing,
the Buyer shall have no rights under this Section IV. G. in respect of Common
Stock or any other securities of the Company issuable (i) upon the exercise or
conversion of options, warrants or other rights to purchase securities of the
Company outstanding as of the date hereof or (ii) to officers, directors or
employees of the Company or any of its subsidiaries. Buyer hereby acknowledges
that other holders of the Series E Preferred Stock may also have the right of
first refusal set forth in this Section I.V., and Buyer hereby agrees that it
shall only be entitled to accept an Offer with respect to its pro rata share of
Right of First Refusal Securities (based on the number of Series E Preferred
Shares held by Buyer relative to the number of Series E Preferred Shares held by
all other holders of Series E Preferred Stock with such right of first refusal
and accepting such Offer).

                        V.  Transfer Agent Instructions


          A.  The Company undertakes and agrees that no instruction other than
the instructions referred to in this Section V and customary stop transfer
instructions prior to the registration and sale of the Common Stock pursuant to
an effective Securities Act registration statement will be given to its transfer
agent for the Common Stock and that the Common Stock issuable upon conversion of
the Preferred Shares and exercise of the Warrants otherwise shall be freely
transferable on the books and records of the Company as and to the extent
provided in this Agreement, the Registration Rights Agreement and applicable
law. Nothing contained in this Section V.A. shall affect in any way Buyer's
obligations and agreement to comply with all applicable securities laws upon
resale of such Common Stock. If, at any time, Buyer provides the Company with an
opinion of counsel reasonably satisfactory to the Company that registration of
the resale by Buyer of such Common Stock is not required under the Securities
Act and that the removal of restrictive legends is permitted under applicable
law, the Company shall permit the transfer of such Common Stock and, promptly
instruct the Company's transfer agent to issue one or more certificates for
Common Stock without any restrictive legends endorsed thereon.


          B.  The Company shall permit Buyer to exercise its right to convert
the Preferred Shares by telecopying an executed and completed Notice of
Conversion (as defined in the Certificate of Designation) to the Company. Each
date on which a Notice of Conversion is telecopied to and received by the
Company in accordance with the provisions hereof shall be deemed a Conversion

                                      -14-


Date (as defined in the Certificate of Designation). The Company shall transmit
the certificates evidencing the shares of Common Stock issuable upon conversion
of any Preferred Shares (together with certificates evidencing any Preferred
Shares not being so converted) to Buyer via express courier, by electronic
transfer or otherwise, within five business days after receipt by the Company of
the Notice of Conversion (the "Delivery Date"). Within 30 days after Buyer
delivers the Notice of Conversion to the Company, Buyer shall deliver to the
Company the Preferred Shares being converted.

          C.  The Company shall permit Buyer to exercise its right to purchase
shares of Common Stock pursuant to exercise of the Warrants in accordance with
its applicable terms of the Warrants. The last date that the Company may deliver
shares of Common Stock issuable upon any exercise of Warrants is referred to
herein as the "Warrant Delivery Date."

          D.  The Company understands that a delay in the issuance of the shares
of Common Stock issuable in lieu of cash dividends on the Preferred Shares, upon
the conversion of the Preferred Shares or exercise of the Warrants beyond the
applicable Dividend Payment Due Date (as defined in the Certificate of
Designation), Delivery Date or Warrant Delivery Date could result in economic
loss to Buyer.  As compensation to Buyer for such loss (and not as a penalty),
the Company agrees to pay to Buyer for late issuance of Common Stock issuable in
lieu of cash dividends on the Preferred Shares, upon conversion of the Preferred
Shares or exercise of the Warrants in accordance with the following schedule
(where "No. Business Days" is defined as the number of business days beyond five
days from the Dividend Payment Due Date, the Delivery Date or the Warrant
Delivery Date, as applicable):

                                      -15-




                                        Compensation For Each 10 Shares

                                        Timely or 500 Shares of Common
                                         Stock Issuable In Payment of
                                         Dividends or Upon Exercise of
                   No. Business Days      Warrants Not Issued Timely

                                         Day Late beyond 10 days


The Company shall pay to Buyer the compensation described above by the transfer
of immediately available funds upon Buyer's demand.  Nothing herein shall limit
Buyer's right to pursue actual damages for the Company's failure to issue and
deliver Common Stock to Buyer, and in addition to any other remedies which may
be available to Buyer, in the event the Company fails for any reason to effect
delivery of such shares of Common Stock within five business days after the
relevant Dividend Payment Due Date, the Delivery Date or the Warrant Delivery
Date, as applicable, Buyer shall be entitled to rescind the relevant Notice of
Conversion or exercise of Warrants by delivering a notice to such effect to the
Company whereupon the Company and Buyer shall each be restored to their
respective original positions immediately prior to delivery of such Notice of
Conversion on delivery.

                           VI.  Delivery Instructions

          The Securities shall be delivered by the Company to the Escrow Agent
pursuant to Section I. B. hereof on a "delivery-against-payment basis" at the
Closing.

                                      -16-


                              VII.  Closing Date

          The date and time of the issuance and sale of the Preferred Shares
(the "Closing Date") shall be the date hereof or such other as shall be mutually
agreed upon in writing.  The issuance and sale of the Securities shall occur on
the Closing Date at the offices of the Escrow Agent.  Notwithstanding anything
to the contrary contained herein, the Escrow Agent shall not be authorized to
release to the Company the Purchase Price and to Buyer the certificate(s) (I/N/O
Buyer or I/N/O Buyer's nominee) evidencing the Securities being purchased by
Buyer unless the conditions set forth in Section VIII. C. and IX. G. hereof have
been satisfied.

                VIII.  Conditions to the Company's Obligations

otherwise prohibiting the consummation of any of the transactions contemplated

have occurred on or prior to the Latest Closing Date, the Closing may only occur
after the Latest Closing Date with the written acceptance of Buyer.

          C.  Termination by Buyer.  This Agreement may be terminated and the
transactions contemplated hereby may be abandoned by Buyer at any time prior to
the Closing Date, if (i) the Company shall have failed to comply with any of its
covenants or agreements contained in this Agreement, (ii) there shall have been
a breach by the Company with respect to any representation or warranty made by
it in this Agreement, (iii) there shall have occurred any event or development,

                                      -18-

in this Agreement.

                        XI.  Survival; Indemnification

          A.  The representations, warranties and covenants made by each of the
Company and Buyer in this Agreement, the annexes, schedules and exhibits hereto
and in each instrument, agreement and certificate entered into and delivered by
them pursuant to this Agreement, shall survive the Closing and the consummation
of the transactions contemplated hereby.  In the event of a breach or violation
of any of such representations, warranties or covenants, the party to whom such
representations, warranties or covenants have been made shall have all rights
and remedies for such breach or violation available to it under the provisions
of this Agreement or otherwise, whether at law or in equity, irrespective of any
investigation made by or on behalf of such party on or prior to the Closing
Date.

          B.  The Company hereby agrees to indemnify and hold harmless the
Buyer, its Affiliates and their respective officers, directors, partners and
members (collectively, the "Buyer Indemnitees"), from and against any and all
losses, claims, damages, judgments, penalties, liabilities and deficiencies
(collectively, "Losses"), and agrees to reimburse the Buyer Indemnitees for all
out of-pocket expenses (including the fees and expenses of legal counsel), in
each case promptly as incurred by the Buyer Indemnitees and to the extent
arising out of or in connection with:

              1.  any misrepresentation, omission of fact or breach of any of
     the Company's representations or warranties contained in this Agreement or
     the other Documents, or the annexes, schedules or exhibits hereto or
     thereto or any instrument, agreement or certificate entered into or
     delivered by the Company pursuant to this Agreement or the other Documents;
     or

              2.  any failure by the Company to perform any of its covenants,
     agreements. undertakings or obligations set forth in this Agreement or the
     other Documents, or the annexes, schedules or exhibits hereto or thereto or
     any instrument, agreement or certificate entered into or delivered by the
     Company pursuant to this Agreement or the other Documents; or

              3.  resales of the Common Shares by Buyer in the manner and as
     contemplated by this Agreement and the Registration Rights Agreement.

          C.  Buyer hereby agrees to indemnify and hold harmless the Company,
its Affiliates and their respective officers, directors, partners and members
(collectively, the "Company Indemnitees"), from and against any and all Losses,
and agrees to reimburse the Company Indemnitees for all out-of-pocket expenses
(including the fees and expenses of legal counsel), in

                                      -19-


each case promptly as incurred by the Company Indemnitees and to the extent
arising out of or in connection with:

              1.  any misrepresentation, omission of fact, or breach of any of
     Buyer's representations or warranties contained in this Agreement or the
     other Documents, or the annexes, schedules or exhibits hereto or thereto or
     any instrument, agreement or certificate entered into or delivered by Buyer
     pursuant to this Agreement or the other Documents; or

              2.  any failure by Buyer to perform in any material respect any
     of its covenants, agreements, undertakings or obligations set forth in this
     Agreement or the other Documents or any instrument, certificate or
     agreement entered into or delivered by Buyer pursuant to this Agreement or
     the other Documents.

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

          E.  In the event one party hereunder should have a claim for
indemnification that does not involve a claim or demand being asserted by a
third party, the Indemnified Party promptly

                                      -20-


shall deliver notice of such claim to the Indemnifying Party. If the Indemnified
Party disputes the claim, such dispute shall be resolved by mutual agreement of
the Indemnified Party and the Indemnifying Party or by binding arbitration
conducted in accordance with the procedures and rules of the American
Arbitration Association. Judgment upon any award rendered by any arbitrators may
be entered in any court having competent jurisdiction thereof.

                      XII.  Governing Law; Miscellaneous

          This Agreement shall be governed by and interpreted in accordance with
the laws of the State of New York, without regard to the conflicts of law
principles of such state.  Each of the parties consents to the jurisdiction of
the federal courts whose districts encompass any part of the City of Palo Alto
or the state courts of the State of California sitting in the City of Palo Alto
in connection with any dispute arising under this Agreement and hereby waives,
to the maximum extent permitted by law, any objection, including any objection
based on forum non conveniens, to the bringing of any such proceeding in such
jurisdictions.  A facsimile transmission of this signed Agreement shall be legal
and binding on all parties hereto.  This Agreement may be signed in one or more
counterparts, each of which shall be deemed an original.  The headings of this
Agreement are for convenience of reference and shall not form part of, or affect
the interpretation of, this Agreement.  If any provision of this Agreement shall
be invalid or unenforceable in any jurisdiction, such invalidity or
unenforceability shall not affect the validity or enforceability of the
remainder of this Agreement or the validity or enforceability of this Agreement
in any other jurisdiction.  This Agreement may be amended only by an instrument
in writing signed by the party to be charged with enforcement.  This Agreement
supersedes all prior agreements and understandings among the parties hereto with
respect to the subject matter hereof.

                                FORM OF OPINION

          1.  The Company has been duly incorporated and is validly existing as
a corporation in good standing under the laws of the State of Delaware, is duly
qualified to do business as a foreign corporation and is in good standing in all
jurisdictions where the Company owns or leases properties or conducts business,
except for jurisdictions in which the failure to so qualify would not have a
Material Adverse Effect, and has all requisite corporate power and authority to
own its properties and conduct its business as described in the Commission
Filings.

          2.  The authorized capital stock of the Company consists of 25,000,000
shares of Common Stock, par value $.001 per share (the "Common Stock"), and
5,000,000 shares of Preferred Stock, par value $.001 per share.

          3.  When delivered to you or upon your order against payment of the
agreed consideration therefor in accordance with the provisions of the
Documents, the Securities will be duly authorized and validly issued, fully paid
and nonassessable.

          4.  The Company has the requisite corporate power and authority to
enter into the Documents and to sell and deliver the Securities as described in
the Documents; each of the Documents has been duly and validly authorized by all
necessary corporate action by the Company; each of the Documents has been duly
and validly executed and delivered by and on behalf of the Company, and is valid
and binding agreement of the Company, enforceable in accordance with its terms,
except as enforceability may be limited by general equitable principles,
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or
other laws affecting creditors rights generally.

          5.  The executive, delivery and performance of the Documents by the
Company and the performance of its obligations thereunder do not and will not
constitute a breach or violation of any of the terms and provisions of, or
constitute a default (or with notice, lapse of time or both would constitute a
default) under or conflict with or violate any provision of (i) the Company's
certificate of incorporation or bylaws, (ii) any indenture, mortgage, deed of
trust, agreement or other instrument known to us to which the Company is a party
or by which it or any of its property is bound, (iii) or, to the best of our
knowledge, any judgment, decree or order of any court or governmental body
having jurisdiction over the Company or any of its property.  To the best of our
knowledge, no consent, approval, authorization, order, registration, filing,
qualification, license or permit of or with any court or any public,
governmental or regulatory agency or body having jurisdiction over the Company
or any of its properties or assets is required for the execution, delivery and
performance by the Company of the Documents or the consummation by the Company
of the transactions contemplated thereby.

          6.  When issued, the Preferred Shares and the Warrants shall be duly
authorized, validly issued, fully paid and nonassessable, and free and clear of
all encumbrances and restrictions, except for restrictions on transfer imposed
by applicable securities laws.  The Conversion Shares and Warrant Shares
issuable upon conversion or exercise, respectively, of the Preferred Shares and
the

                                      -37-


Warrants, respectively, will be duly authorized, validly issued, fully paid and
nonassessable, and free and clear of all encumbrances and restrictions, except
for restrictions on transfer imposed by applicable securities laws.

          7.  Based on Buyer's representations contained in this Agreement, the
offer and sale of the Preferred Shares and the Warrants are exempt from the
registration requirements of the Securities Act.

          8.  To the best of our knowledge, other than as described in the
Commission Filings, there are no outstanding options, warrants or other
securities exercisable or convertible into Common Stock of the Company.

          9.  There is no action, suit, claim, inquiry or investigation pending
or, to the best of our knowledge, threatened by or before any court or public or
governmental authority which, if determined adversely to the Company, would have
a Material Adverse Effect.

          10. Neither the Company nor any of its subsidiaries is, or will be
after the consummation of the transactions contemplated by this Agreement and
the other Documents and the use of the proceeds from the sale of the Securities,
an "investment company" or an entity "controlled" by an "investment company," as
such terms are defined in the Investment Company Act of 1940, as amended.

                                      -38-
