                              DALEEN HOLDINGS, INC.

                       FORM OF INDEMNITY PROMISSORY NOTE
                                (NON-NEGOTIABLE)

$1,650,000.00                                                Boca Raton, Florida

         Daleen Holdings, Inc. (the "Obligor"), a Delaware corporation, for
value received, hereby promises to pay to ___________ ("Holder"), in Holder's
capacity as the Sellers' Rep and for the benefit of the Sellers, in lawful money
of the United States at the address of the Holder set forth below, the initial
principal amount of One Million Six Hundred Fifty Thousand Dollars
($1,650,000.00). All terms not defined herein shall have the meanings given to
them in the Stock Purchase Agreement, dated May 7, 2004 (the "Stock Purchase
Agreement"), among the Obligor, Protek Telecommunications Solutions Limited, a
company formed under the laws of England and Wales ("Protek"), and the
stockholders and optionholders of Protek party thereto. This Note is the
Indemnity Note provided for under the Stock Purchase Agreement. The obligations
of the Company under this Note are secured by the deposit of an aggregate of
$1,650,000 with the Escrow Agent.

         1. Principal and Interest. The outstanding principal amount of this
Note shall bear interest at a rate equal to (a) the rate payable from time to
time on funds held in the account established by the Escrow Agent plus (b) the
applicable Penalty Rate on the amount of the First Mandatory Prepayment or
Second Mandatory Prepayment, as the case may be, if such payments have not been
made on or before April 30, 2005 and April 30, 2006 respectively. Interest
accrued with respect to any portion of the principal amount hereof shall be
payable concurrent with delivery of such amount. Interest shall be calculated
using the actual number of days elapsed during the applicable interest period
and a calendar year of 365 or 366 days, as applicable. The outstanding principal
amount of this Note shall be subject to mandatory prepayment and reduction from
time to time as described in the Stock Purchase Agreement and in Sections 2 and
3 below.

         For purposes of this Note, the "Penalty Rate" shall mean (a) 100 basis
points or (b) for any period of accrual of the Penalty Rate during which
Watterson is no longer employed by the Obligor or any of its subsidiaries, 300
basis points.

         The Note may be prepaid without penalty, in whole or in part, at any
time. Upon payment in full of all principal and interest payable hereunder, this
Note shall be surrendered to Obligor for cancellation.

<PAGE>

         Any payments to be made to Holder hereunder shall be made to Holder in
his capacity as Sellers' Rep, and shall be made by wire transfer of immediately
available funds to such accounts as Holder shall designate by written notice to
the Obligor, such notice to specify the proportions in which such payments are
to be allocated among such accounts.

         2. Mandatory Prepayments; Maturity. (a) First Mandatory Prepayment. If,
as of the 30th calendar day after the receipt by Buyer of its audited financial
statements for fiscal year ending December 31, 2004, the excess, if any, of (x)
the outstanding principal amount of this Note over (y) the aggregate amount of
all good faith claims made by the Buyer Indemnitees pursuant to Section 11 of
the Stock Purchase Agreement (such excess, the "Unclaimed Principal Amount") is
equal to or greater than seventy-five percent (75%) of the initial principal
amount of this Note, then fifty percent (50%) of the Unclaimed Principal Amount
shall be paid to the Holder, together with interest accrued thereon in
accordance with Section 1 of this Note (the "First Mandatory Prepayment"). For
the purpose of avoidance of doubt, it is acknowledged for purposes of this
Section 2 that in respect of any third party claim a Buyer Indemnitee shall have
a good faith claim in respect of the full amount (including Buyer's reasonable
estimate of attorneys fees and costs) claimed by such third party (or, if no
specific amount is claimed, Buyer's good faith determination of such Buyer
Indemnitee's maximum exposure if all claims presented by such third party
claimant were to be finally determined adversely to such Buyer Indemnitee).

         (b) Second Mandatory Prepayment. If, as of the 30th calendar day after
the receipt by Buyer of its audited financial statements for fiscal year ending
December 31, 2005, there remains any Unclaimed Principal Amount under this Note,
then such Unclaimed Principal Amount shall be paid to the Holder, together with
interest accrued thereon in accordance with Section 1 of this Note (the "Second
Mandatory Prepayment").

         (c) Further Mandatory Prepayments. From and after the date on which the
Second Mandatory Prepayment is paid or, if an Unclaimed Principal Amount then
existed, would have been made, upon each resolution of an outstanding claim for
indemnification in accordance with Section 3 below, a calculation of the
Unclaimed Principal Amount after giving effect to such determination shall be
made and the Unclaimed Principal Amount, if any, released.

         (d) Maturity. The outstanding principal amount and accrued but unpaid
interest on this Note shall mature and become immediately due and payable upon
the fifth business day after the final determination of all claims for
indemnification made by any Buyer Indemnitee under Section 11 of the Stock
Purchase Agreement. All mandatory prepayments described in clauses (a) through
(c) preceding shall be immediately due and payable upon the fifth business day
after the date of the respective determination provided for therein.

         3. Reduction of Amounts Owing. Upon the earlier of (x) the 20th
business day after delivery by a Buyer Indemnitee of a written claim for
indemnification under Section 11 of the Stock Purchase Agreement if the Sellers'
Rep has not delivered to the Buyer a written notice of objection to such claim
by such day, (y) the date of a written agreement between the Sellers' Rep and
such Buyer Indemnitee establishing the amount of such claim to be indemnified
and (z) a final and binding adjudication of such claim for indemnification, the
outstanding principal amount of this Note shall be reduced by (a) if pursuant to
clause (x) preceding, the amount so claimed, (b) if pursuant to clause (y)
preceding, the agreed upon amount, or (c) if pursuant to clause (z) preceding,

                                     - 2 -

<PAGE>

the amount of indemnification to which such Buyer Indemnitee is so determined to
be entitled. Accrued but unpaid interest on this Note shall be reduced by the
amount of interest attributable to such reduction of principal. For the
avoidance of doubt, no sum shall be payable under this Note other than from sums
that are held within the Indemnity Escrow Account, and the Holder undertakes not
to seek payment of any sum under this Note other than from the sums held in the
Indemnity Escrow Account. The Obligor confirms that it shall execute and deliver
such written instructions to the Escrow Agent as are required by the Stock
Purchase Agreement to be delivered by the Obligor in order to effect the release
of funds from the Escrow Account in accordance with the terms of the Stock
Purchase Agreement.

         4. Presentation of Note on Payment or Other Adjustment. In the event
that the outstanding principal amount of this Note is reduced pursuant to its
terms, including by payment or reduction pursuant to Section 3, the Obligor may
at any time thereafter and in its sole discretion request that the Holder
present this Note at the principal offices of the Holder or at such other
location (including the offices of Holder's English counsel) for notation
thereon of, or attachment thereto of an allonge evidencing, such payment and/or
reduction. This right has been granted for the protection and convenience of the
Obligor, and any reduction of the principal amount and accrued but unpaid
interest on this Note in accordance with the terms hereof shall be effective and
binding irrespective of any failure of the Obligor to request presentation of
this Note for such notation or attachment.

         5. Assignment. This Note may not be assigned or transferred in whole or
in part without the prior written consent of the Obligor and the Holder, other
than a transfer in whole to an entity that controls, is controlled by, or is
under common control with the Holder.

         6. Default. Upon default in the payment of any amount due under this
Note, in addition to any other remedy the Holder may exercise, if the default in
payment is not cured by the Obligor within ten Business Days after notice, the
rate of interest accruing on the unpaid principal balance of the Note may, at
the Holder's option, be increased by the Penalty Rate.

          7. Governing Law. This Note shall be governed in all respects by the
internal laws of the State of New York.

          8. Other Agreements. This Note is subject to the additional terms and
conditions set forth in the Stock Purchase Agreement.

          9. Invalidity of Terms. In case any one or more of the provisions
contained in this Note shall be invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions
of this Note shall in not way be affected or impaired thereby.

          10. Waiver of Jury Trial. THE OBLIGOR AND, BY ACCEPTANCE OF THIS NOTE,
THE HOLDER EACH IRREVOCABLY WAIVE ANY AND ALL RIGHT THEY MAY HAVE TO A TRIAL BY
JURY IN ANY ACTION, PROCEEDING OR CLAIM OF ANY NATURE ARISING FROM OR RELATING
TO THIS NOTE, ANY DOCUMENTS EXECUTED IN CONNECTION HEREWITH (INCLUDING THE STOCK
PURCHASE AGREEMENT), ANY TRANSACTIONS CONTEMPLATED IN ANY OF SUCH DOCUMENTS. THE
PARTIES ACKNOWLEDGE THAT THE FOREGOING WAIVER IS KNOWING AND VOLUNTARY.

               SERIES A CONVERTIBLE REDEEMABLE PIK PREFERRED STOCK

                              INVESTMENT AGREEMENT

                                AS OF MAY 7, 2004

      The parties to this Series A Convertible Redeemable PIK Preferred Stock
Investment Agreement (this "Agreement") are Daleen Holdings, Inc., a newly
formed Delaware corporation (the "Company"), Quadrangle Capital Partners LP, a
Delaware limited partnership, Quadrangle Select Partners LP, a Delaware limited
partnership, Quadrangle Capital Partners-A LP, a Delaware limited partnership
(collectively, the "Quadrangle Investors"), Behrman Capital II, L.P., a Delaware
limited partnership ("Behrman"), Strategic Entrepreneur Fund II, L.P., a
Delaware limited partnership ("SEF," and, together with Behrman, the "Behrman
Investors"), and any other investors who now or hereafter become signatories to
this Agreement (each, including each Quadrangle Investor and each Behrman
Investor, an "Investor" and collectively, the "Investors"; together with the
Company, the "Parties"). Certain terms used in this Agreement, but not otherwise
defined in context, are defined in Section 9.1.

      A.    The Company is seeking funding for general corporate and working
capital purposes and to effect the closing of the Daleen Merger (as defined
below) and the Protek Stock Purchase (as defined below). In this connection, the
Company desires to issue and sell at least 300,000 shares of its Series A
Convertible Redeemable PIK Preferred Stock, par value $0.01 per share (the
"Series A Preferred Stock"), for an aggregate purchase price of $30,000,000 (the
"Minimum Offering Amount"). The offering of the Series A Preferred Stock on the
terms and subject to the conditions described in this Agreement, including the
Exhibits hereto, is referred to in this Agreement as the "Offering." Each
Investor desires to purchase shares of Series A Preferred Stock from the
Company, all on the terms and subject to the conditions set forth in this
Agreement. The per share purchase price for each share of Series A Preferred
Stock to be sold pursuant to this Agreement is $100 (the "Offering Price").

      B.    Concurrently with, or immediately following, the closing of the
transactions described in this Agreement, the Company intends to (i) cause its
newly formed, wholly-owned Subsidiary, Parallel Acquisition, Inc., a Delaware
corporation ("Merger Sub"), to merge with and into Daleen Technologies, Inc., a
Delaware corporation ("Daleen"), pursuant to the Daleen Merger Agreement (the
"Daleen Merger") and (ii) purchase all of the shares of the outstanding capital
stock of Protek Telecommunications Solutions Limited, a company organized under
the laws of England and Wales ("Protek"), pursuant to the Protek Stock Purchase
Agreement (the "Protek Stock Purchase"). Upon consummation of the Daleen Merger
and the Protek Stock Purchase, each of Daleen and Protek will be a wholly-owned
Subsidiary of the Company.

      C.    As a condition to the closing of the transactions described in this
Agreement, the Parties shall enter into the Transaction Documents.

      Accordingly, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the Parties, intending to
be legally bound, agree as follows:

<PAGE>

      1.    Sale of Series A Preferred Stock.

            (a)   Subject to the other provisions of this Agreement, the Company
shall issue and sell to each Quadrangle Investor, and each Quadrangle Investor
shall purchase from the Company, shares of Series A Preferred Stock in the
amount set forth next to the name of each Quadrangle Investor on the signature
pages to this Agreement, for a price per share equal to the Offering Price,
payable by wire transfer of immediately available funds at the Closing (as
defined below).

            (b)   Subject to the other provisions of this Agreement, the Company
shall issue and sell to each Behrman Investor, and each Behrman Investor shall
purchase from the Company, shares of Series A Preferred Stock in the respective
amounts set forth next to the name of each Behrman Investor on the signature
pages to this Agreement (subject to the reduction of such amounts pursuant to
Section 1(c)), for a price per share equal to the Offering Price, payable by the
sale and assignment to the Company by the Behrman Investors at the Closing of
the promissory notes issued to the Behrman Investors under the Bridge Loan
Agreement, in accordance with the Note Purchase Agreement.

            (c)   As soon as is practicable after the date hereof (subject to
compliance with any applicable law), the Company shall give written notice to
each holder of Series F Convertible Preferred Stock, par value $0.01 per share,
of Daleen (each, a "Series F Holder") of the sale of Series A Preferred Stock to
the Behrman Investors contemplated by the preceding Section 1(b). If any Series
F Holder notifies the Company of its desire to purchase shares of Series A
Preferred Stock within ten (10) days after the date of the Company's written
notice and prior to the Closing (each, an "Additional Investor" and
collectively, the "Additional Investors"), the aggregate number of shares of
Series A Preferred Stock to be purchased by each Behrman Investor shall be
reduced, on a pro rata basis, by the aggregate number of shares of Series A
Preferred Stock to be sold to such Additional Investor(s), and each such
Additional Investor, as a condition to such purchase, shall become a party to
this Agreement as an "Investor" by executing and delivering counterpart
signature pages hereto and shall enter into the other Transaction Documents with
the other Parties hereto. The Additional Investors may purchase aggregate shares
of Series A Preferred Stock pursuant to this Section 1(c) with a maximum
aggregate Offering Price of $1,000,000 (the "Additional Investors Maximum
Purchase Amount"). If the Additional Investors desire collectively to purchase
shares of Series A Preferred Stock in excess of the Additional Investors Maximum
Purchase Amount, the Additional Investors Maximum Purchase Amount shall be
purchased by the Additional Investors and shall be allocated among the
Additional Investors pro rata based upon the amounts set forth in the written
notices furnished to the Company by the Additional Investors.

            (d)   The shares of Series A Preferred Stock sold and purchased
pursuant to this Agreement shall have the designations, powers, preferences, and
other special rights and limitations set forth in the Certificate of
Incorporation attached as Exhibit A to this Agreement (the "Certificate of
Incorporation") and the Certificate of Designations of Series A Convertible
Redeemable PIK Preferred Stock attached as Exhibit B to this Agreement (the
"Certificate of

<PAGE>

Designations"), each of which shall be adopted and filed by the Company with the
Secretary of State of the State of Delaware.

      2.    Closing. The closing of the purchase and sale of the Series A
Preferred Stock to the Investors (the "Closing") shall take place at the offices
of Kirkpatrick & Lockhart LLP located at 599 Lexington Avenue, New York, New
York, upon satisfaction or waiver of the conditions set forth in Section 6 and
immediately prior to, or concurrent with, the consummation of the transactions
contemplated by the Daleen Merger Agreement and the Protek Stock Purchase
Agreement, unless otherwise agreed to by the Company, the Quadrangle Investors,
and the Behrman Investors. At the Closing, the Company shall deliver to each
Investor a certificate or certificates in definitive form representing the
respective number of shares of Series A Preferred Stock being purchased by such
Investor under this Agreement, against payment to the Company of the purchase
price for the shares of Series A Preferred Stock by certified check, wire
transfer, or any combination thereof. The date and time of the Closing is
hereinafter referred to as the "Closing Date."

      3.    Reserved.

      4.    Representations and Warranties of the Company. The Company
represents and warrants to each Investor as follows:

            4.1.  Organization. The Company and Merger Sub are corporations
incorporated, validly existing, and in good standing under the laws of the State
of Delaware, and each of the Company and Merger Sub has the requisite power and
authority to own and operate its properties and to carry on its business as now
conducted and as proposed to be conducted. Each of the Company and Merger Sub is
qualified to do business as a foreign corporation and is in good standing in
each jurisdiction where the conduct of its business or the ownership of its
properties currently requires such qualification and being in good standing,
except where the failure to be so qualified or in good standing would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. The term "Material Adverse Effect" means any change or effect
that is or is reasonably likely to be materially adverse to the business,
results of operations, or financial condition of the Company and its
Subsidiaries taken as a whole, or otherwise affects the ability of the Company
to consummate the transactions contemplated hereby, except for such changes or
effects that are the result of general economic conditions affecting the
Company's industry generally. The Company is a newly formed corporation that was
incorporated to effect the transactions contemplated in this Agreement, the
Daleen Merger Agreement and the Protek Stock Purchase Agreement. Merger Sub is a
newly formed, wholly-owned Subsidiary of the Company that was incorporated to
effect the transactions contemplated in the Daleen Merger Agreement. Neither the
Company nor Merger Sub has conducted any business other than as set forth in or
contemplated by this Agreement, the Daleen Merger Agreement, and the Protek
Stock Purchase Agreement.

            4.2.  Power and Authority. The Company has the requisite power and
authority to enter into this Agreement and the other Transaction Documents and
to perform its obligations hereunder and thereunder and to consummate the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the other Transaction Documents, and the performance by the
Company of its obligations hereunder and thereunder and the consummation

<PAGE>

of the transactions contemplated hereby or thereby have been duly and validly
authorized by all necessary action on the part of the Company, its Board of
Directors and stockholders. This Agreement is and, as of the Closing, each of
the other Transaction Documents will be a valid and binding obligation of the
Company, enforceable against it in accordance with its terms, subject to
bankruptcy, insolvency, fraudulent conveyance and transfer, reorganization,
receivership, moratorium, and other laws affecting the rights and remedies of
creditors generally and to the general principles of equity. The shares of
Series A Preferred Stock (together with the shares of Common Stock (as defined
in Section 4.3(a) below) issuable upon conversion of the shares of Series A
Preferred Stock) to be issued, sold, and delivered in accordance with the terms
of this Agreement have been duly authorized by all required action of the
Company's Board of Directors and its stockholders.

            4.3.  Capitalization.

                  (a)   The Company's authorized capital stock consists of
4,000,000 shares of Common Stock, $0.01 par value per share (the "Common
Stock"), of which no shares are issued and outstanding as of the date hereof,
and 500,100 shares of Preferred Stock, $0.01 par value per share, of which 100
shares have been designated as Junior Preferred Stock, all of which are issued
and outstanding as of the date hereof and held of record and beneficially by
Daleen.

                  (b)   Except as contemplated by this Agreement, the Daleen
Merger Agreement or the Protek Stock Purchase Agreement, no equity securities
are required to be issued by the Company or Merger Sub by reason of any
currently existing options, warrants, rights to subscribe to, calls or
commitments of any character whatsoever relating to, or securities or rights
convertible into, shares of any capital stock of the Company or Merger Sub, as
applicable, and there are no Contracts, commitments, understandings, or
arrangements by which the Company or Merger Sub is bound to issue additional
shares of its respective capital stock, or options, warrants or rights to
purchase or acquire any additional shares of its respective capital stock. The
Company is not a party or subject to any agreement or understanding, nor, to the
Knowledge of the Company, is there any agreement or understanding between any
persons that affects or relates to the voting or giving of written consents with
respect to any security or the voting by a director of the Company.

            4.4.  Valid Issuance. The Series A Preferred Stock that is being
purchased by the Investors hereunder, when issued, sold, and delivered in
accordance with the terms of this Agreement for the consideration expressed
herein, will be duly and validly issued, fully paid, and nonassessable, and will
be free of restrictions on transfer other than restrictions on transfer under
the Transaction Documents and under applicable state and federal securities
laws. The Common Stock issuable upon conversion of the Series A Preferred Stock
being purchased under this Agreement has been duly and validly reserved for
issuance and, upon issuance in accordance with the terms of the Certificate of
Incorporation and Certificate of Designations, will be duly and validly issued,
fully paid, and nonassessable and will be free of restrictions on transfer other
than restrictions on transfer under the Transaction Documents and under
applicable state and federal securities laws.

            4.5.  Registration Rights. Except as contemplated in the Transaction
Documents, Daleen Merger Agreement, or the Protek Stock Purchase Agreement, the
Company

<PAGE>

is presently not under any obligation and has not granted any rights to register
under the Securities Act of 1933, as amended (the "Securities Act"), any of its
presently outstanding securities or any of its securities that may be
subsequently issued.

            4.6.  Subsidiaries. The Company owns, beneficially and of record,
all of the outstanding capital stock of Merger Sub. The Company does not own,
nor has it ever owned, directly or indirectly, any equity interest in any other
corporation, partnership, limited liability company, joint venture or other
entity.

            4.7.  Offerees; Regulation D. None of the Company, its directors and
officers, its Affiliates nor, to the Company's Knowledge, any Person acting as
an agent for or on behalf of the Company has, directly or indirectly, sold,
offered for sale, or solicited offers to buy any of the shares of Series A
Preferred Stock by means of any form of general solicitation or general
advertising or otherwise so as to bring the offer, issuance or sale of the
shares of Series A Preferred Stock as contemplated by this Agreement within the
registration requirements of Section 5 of the Securities Act, or within the
registration or qualification requirements of any "blue sky" or securities laws
of any state or other jurisdiction of the United States of America. Assuming
each Investor hereunder is an "accredited investor" within the meaning of
Regulation D under the Securities Act, the offering, issuance and sale of the
shares of Series A Preferred Stock pursuant to this Agreement is exempt from the
registration provisions of the Securities Act and neither the Company, nor any
authorized representative, will take any action that would result in the loss of
such exemption. The Company is not disqualified from relying on the exemption
provided in Regulation D under the Securities Act as provided in Rule 507 of
Regulation D.

            4.8.  Litigation. Except as set forth on Schedule 4.8, there is no
litigation or governmental proceeding or investigation pending or, to the
knowledge of the Company, threatened against the Company or Merger Sub or
affecting any of their properties or assets.

            4.9.  Compliance with Laws and Other Instruments. The Company is in
compliance with all applicable provisions of this Agreement, the Daleen Merger
Agreement, the Protek Stock Purchase Agreement and of its respective charter and
bylaws, and, in all material respects with the applicable provisions of each
statute and regulation by which it is bound or to which it or its properties are
subject. Neither the execution, delivery or performance of this Agreement and
the other Transaction Documents nor the consummation of the transactions
contemplated hereby and thereby, nor the offer, issuance, sale or delivery of
the shares of Series A Preferred Stock, with or without the giving of notice or
passage of time, or both, will violate, or result in any breach of, or
constitute a default under, or result in the imposition of any encumbrance upon
any asset of the Company pursuant to any provision of its charter or bylaws, or
any statute, rule or regulation, or other document or instrument by which the
Company is bound or to which it or any of its properties are subject.

            4.10. Real Property. Neither the Company nor the Merger Sub own,
lease or have any other interest in any real property.

            4.11. Employee Matters. Except as set forth on Schedule 4.11,
neither the Company nor the Merger Sub has any employees nor do they have in
effect any employment

<PAGE>

agreements, consulting agreements, deferred compensation, severance, pension or
retirement agreements or arrangements, bonus, incentive or profit-sharing plans
or arrangements, or labor or collective bargaining agreements, written or oral.

            4.12. Contracts and Commitments. Except for, and as contemplated by,
this Agreement, any other Transaction Document, the Daleen Merger Agreement and
the Protek Stock Purchase Agreement, neither the Company nor the Merger Sub is
subject to any additional Contracts, obligations or commitments.

            4.13. No Brokers or Finders. No person has or will have, as a result
of the transactions contemplated by this Agreement, any right, interest or claim
against or upon the Company for any commission, fee or other compensation as a

            4.14. Assumptions, Guarantees, etc. of Indebtedness of Other
Persons. Neither the Company nor the Merger Sub has assumed, guaranteed,
endorsed or otherwise become directly or contingently liable on or for any
indebtedness for borrowed money of any other Person.

            4.15. Daleen Merger Agreement and Protek Stock Purchase Agreement.
All representations and warranties of the Company and the Merger Sub set forth
in the Daleen Merger Agreement and the Protek Stock Purchase Agreement are true
and correct in all material respects as of the date hereof, and subject to any
updated schedules permitted thereunder, will be true and correct in all material
respects as of the Closing, except for any inaccuracies that would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on the Company.

            4.16. No Other Representations or Warranties. Except as expressly
set forth in this Section 4, the Company makes no other representation or
warranty, express or implied, at law or in equity, with respect to the Company,
the Company's business operations or future financial performance, or the Series
A Preferred Stock.

      5.    Representations and Warranties of the Investors. Each Investor
hereunder, severally and not jointly, represents and warrants to the Company as
follows:

            5.1.  Finders. No broker's, finder's or any similar fee has been or
will be incurred by or on behalf of the Investor in connection with the origin,
negotiation, execution or delivery of this Agreement or the consummation of the
transactions contemplated hereby.

            5.2.  Investment Representations.

            (a)   The Investor understands that the shares of Series A Preferred
Stock and any shares of Common Stock issued on conversion thereof have not been
registered under the Securities Act, or any state or foreign securities act and
are being issued to the Investor by reason of specific exemptions under the
provisions thereof that depend in part upon the other representations and
warranties made by the Investor in this Agreement.

<PAGE>

            (b)   The Investor understands that the shares of Series A Preferred
Stock and any shares of Common Stock issued on conversion thereof are
"restricted securities" under applicable federal securities laws and that the
Securities Act and the rules of the Securities and Exchange Commission
promulgated thereunder provide in substance that the Investor may dispose of
shares of Series A Preferred Stock only pursuant to an effective registration
statement under the Securities Act or an exemption from registration, if
available.

            (c)   The Investor is acquiring the shares of Series A Preferred
Stock for investment only and not with a view to, or in connection with, any
resale or distribution of any of the shares of Series A Preferred Stock. The

transfer or other disposition of its shares of Series A Preferred Stock or any
interest therein.

            (d)   The Investor has not received, paid or given, directly or
indirectly, any commission or remuneration for or on account of any sale, or the
solicitation of any sale, of the shares of Series A Preferred Stock.

            (e)   The Investor is an "accredited investor" as such term is
defined in Rule 501 under Regulation D promulgated under the Securities Act and
was not organized for the specific purpose of acquiring shares of Series A
Preferred Stock.

            (f)   The Investor has sufficient Knowledge and experience in
investing in companies similar to the Company in terms of the Company's early
stage of development so as to be able to evaluate the risks and merits of its
investment in the Company's Series A Preferred Stock and it is able financially
to bear the risks thereof.

            (g)   The Investor has had an opportunity to discuss the Company's
business, management, and financial affairs with the Company's executive
officers. The Investor has also had an opportunity to ask questions and receive
answers from the executive officers of the Company concerning the terms and
conditions of the offering of the Series A Preferred Stock and to obtain the
information it believes necessary or appropriate to evaluate the suitability of
an investment in the Series A Preferred Stock.

            5.3.  Organization; Authority; Enforceability. The Investor has full
power and authority to enter into this Agreement and the other Transaction
Documents and to perform fully its obligations hereunder and thereunder and to
consummate the transactions contemplated hereby and thereby. The Investor has
the funds, or access to the funds, necessary to perform fully its obligations
hereunder. The execution and delivery of this Agreement and the other
Transaction Documents and the performance by the Investor of its obligations
hereunder and thereunder and the consummation of the transactions contemplated
hereby and thereby have been duly and validly authorized by all necessary action
on the part of the Investor. Each of this Agreement and the other Transaction
Documents is a valid and binding obligation of the Investor, enforceable against
it in accordance with its terms, subject to bankruptcy, insolvency, fraudulent
conveyance and transfer, reorganization, receivership, moratorium, and other
similar laws affecting the rights and remedies of creditors generally and to the
general principles of equity.
