               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

have no further force or effect, with no liability on the part of the Company
and the Investors, or their respective directors, officers, agents or

thereof.

other circumstances in connection with this Agreement, the other Transaction
Documents, or the Offering and, (c) to the extent permitted by applicable law,
hereby waives, and agrees not to assert, by way of motion, as a defense, or
otherwise, in any such suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of such court or that the suit, action or
proceeding is improper.

            9.13. Certain Understandings. This Agreement does not constitute a
partnership or joint venture among the Parties.

            9.14. Attorneys' Fees. If any action at law or in equity is
