                         SUPPLEMENTAL VOTING AGREEMENT

L.P. (together, the "Behrman Entities").

     A. Daleen Technologies, Inc. ("Daleen"), and the Behrman Entities are
entering concurrent with the execution of this Agreement into an Investment

are investing approximately $5 million into securities and warrants issued by

by the Asset Purchase Agreement, of even date herewith, among Abiliti, Daleen
and Daleen Solutions, Inc. (the "Purchase Agreement") and the transactions
contemplated by the Investment Agreement, of even date herewith, among Daleen
and the Behrman Entities (the "Investment Agreement"), will be, holders of the
capital stock of Daleen.

     B. It is a condition to the execution and delivery of the Investment

Entities commit to vote at the next annual meeting of stockholders in favor of
the election as Class I Directors of Daleen, of one individual to be designated
by the HarbourVest Entities.

     Accordingly, the parties hereto agree as follows:

     SECTION 1.  Restrictions on Transfer.  Until the termination of this
Agreement in accordance with its terms, each Stockholder and each Behrman Entity
agrees not to Transfer (or to agree to Transfer) any shares of the capital stock
of Daleen ("Shares") owned of record or beneficially by such Stockholder or
Behrman Entity; provided, however, that nothing herein shall prohibit a
Stockholder or any Behrman Entity from making a Transfer of (or agreeing to
Transfer) any Shares to any Affiliate (and, in the case of Abiliti, any
creditor) of such Stockholder or Behrman Entity that prior to such Transfer has
assumed such Stockholder's or Behrman Entity's, as the case may be, obligations
under this Agreement by a written agreement in form and substance reasonably
satisfactory to the HarbourVest Funds and the Behrman Entities. "Transfer"
means, with respect to any security, the direct or indirect assignment, sale,
transfer, tender, pledge, hypothecation, or the grant, creation or suffrage of a
lien or encumbrance in or upon, or the gift, placement in trust, or the
constructive sale or other disposition of such security (including transfers by
testamentary or intestate succession) or any right, title or interest therein
(including but not limited to any right or power to vote to which the holder
thereof may be entitled, whether such right or power is granted by proxy or
otherwise), or the record or beneficial ownership thereof, the offer to make
such a sale, transfer, or other disposition of voting rights with respect to the
Shares, and each agreement, arrangement or understanding, whether or not in
writing, to effect any of the foregoing. The term "Affiliate" is used in this
Agreement as defined in Rule 12b-2 under the Securities Exchange Act of 1934.

     SECTION 2.  Agreement to Vote.  Until the termination of this Agreement in
accordance with its terms, and conditioned solely upon the consummation of the
transactions contemplated by the Purchase Agreement and the Investment Agreement
having occurred, each Stockholder and Behrman Entity hereby irrevocably and
unconditionally agrees to vote or to cause to be voted all of its Shares, to the
extent the Shares carry the right to vote thereon, at the 2003 annual meeting of
stockholders of Daleen or any postponement or continuation thereof, and in
connection with any written consent of stockholders in lieu thereof, in favor of
the election of the two persons who will be designated by the Behrman Entities
and nominated by Daleen as Class I Directors of Daleen (the "Behrman Designees")
and in favor of the election of the one person who will be designated by the
HarbourVest Funds and nominated by Daleen as


                                       1
<PAGE>

Class I Directors of Daleen (the "HarbourVest Designee"), and against the
election of any nominees other than the Behrman Designees and the HarbourVest
Designee.

     SECTION 3.  Granting of Proxy.

     (a) In furtherance of the terms and provisions of this Agreement, each
Stockholder hereby grants, conditioned solely upon the consummation of the
transactions contemplated by the Purchase Agreement and the Investment Agreement
having occurred, an irrevocable proxy (subject to Section 8(b)), coupled with an
interest, to each of the Behrman Entities, for the sole purpose to vote all of
the Shares beneficially owned by such Stockholder in favor of the election of
the Behrman Designees in accordance with the provisions of Section 2. Each
Stockholder hereby ratifies and approves of each and every action taken by each
of the Behrman Entities pursuant to the foregoing proxy. Notwithstanding the
foregoing, if requested by the Behrman Entities, each Stockholder will execute
and deliver applicable proxy material in furtherance of the provisions of
Section 2 and this Section 3.

     (b) In furtherance of the terms and provisions of this Agreement, each of
Abiliti and the Behrman Entities hereby grants, conditioned solely upon the
consummation of the transactions contemplated by the Purchase Agreement and the
Investment Agreement having occurred, an irrevocable proxy (subject to Section
8(b)), coupled with an interest, to each of the HarbourVest Funds, for the sole
purpose to vote all of the Shares beneficially owned by Abiliti and the Behrman
Entities in favor of the election of the HarbourVest Designee in accordance with
the provisions of Section 2. Abiliti and each Behrman Entity hereby ratifies and
approves of each and every action taken by each of the HarbourVest Funds
pursuant to the foregoing proxy. Notwithstanding the foregoing, if requested by
the HarbourVest Funds, each of Abiliti and each Behrman Entity will execute and
deliver applicable proxy material in furtherance of the provisions of Section 2
and this Section 3.

     SECTION 4.  Invalid Provisions.  If any provision of this Agreement shall
be invalid or unenforceable under applicable law, such provision shall be
ineffective to the extent of such invalidity or unenforceability only, without
it affecting the remaining provisions of this Agreement.

     SECTION 5.  Executed in Counterparts.  This Agreement may be executed in
counterparts each of which shall be an original with the same effect as if the
signatures hereto and thereto were upon the same instrument.

     SECTION 6.  Specific Performance.

     (a) The parties hereto agree that the failure for any reason of a
Stockholder to perform any of his or its agreements or obligations under this
Agreement would cause irreparable harm or injury to the Behrman Entities with
respect to which money damages would not be an adequate remedy. Accordingly,
each Stockholder agrees that, in seeking to enforce this Agreement against such
Stockholder, the Behrman Entities shall be entitled to specific performance and
injunctive and other equitable relief in addition to any other remedy available
at law, equity or otherwise.

     (b) The parties hereto agree that the failure for any reason of either
Abiliti or any Behrman Entity to perform any of his or its agreements or
obligations under this Agreement would cause irreparable harm or injury to the
HarbourVest Funds with respect to which money damages would not be an adequate
remedy. Accordingly, each of Abiliti and each Behrman Entity agrees that, in
seeking to enforce this Agreement against such person or entity, the HarbourVest
Funds shall be entitled to specific performance and injunctive and other
equitable relief in addition to any other remedy available at law, equity or
otherwise.

     SECTION 7.  GOVERNING LAW; SUBMISSION TO JURISDICTION.  THE AGREEMENT SHALL
BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE DOMESTIC LAWS
OF THE STATE OF DELAWARE WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT
OF LAW PROVISION OR RULE (WHETHER OF THE STATE OF DELAWARE OR ANY OTHER
JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION
OTHER THAN THE STATE OF DELAWARE. EACH OF THE PARTIES HERETO IRREVOCABLY AGREES
THAT ANY

LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR FOR RECOGNITION AND
ENFORCEMENT OF ANY JUDGMENT IN RESPECT HEREOF BROUGHT BY ANY OTHER PARTY HERETO
OR ITS SUCCESSORS OR ASSIGNS SHALL BE BROUGHT AND DETERMINED IN THE STATE AND
FEDERAL COURTS OF THE STATE OF MASSACHUSETTS, AND EACH OF THE PARTIES HERETO
HEREBY IRREVOCABLY SUBMITS WITH REGARD TO ANY SUCH ACTION OR PROCEEDING FOR
ITSELF AND IN RESPECT TO ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, TO THE
NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. EACH OF THE PARTIES HERETO
HEREBY IRREVOCABLY WAIVES, AND AGREES NOT TO ASSERT, BY WAY OF MOTION, AS A
DEFENSE, COUNTERCLAIM OR OTHERWISE, IN ANY ACTION OR PROCEEDING WITH RESPECT TO
THIS AGREEMENT, ANY CLAIM (A) THAT IT IS NOT PERSONALLY SUBJECT TO THE
JURISDICTION OF THE AFORESAID COURTS FOR ANY REASON, (B) THAT IT OR ITS PROPERTY
IS EXEMPT OR IMMUNE FROM JURISDICTION OF ANY SUCH COURT OR FROM ANY LEGAL
PROCESS COMMENCED IN SUCH COURTS (WHETHER THROUGH SERVICE OF JUDGMENT, EXECUTION
OF JUDGMENT, OR OTHERWISE), AND (C) TO THE FULLEST EXTENT PERMITTED BY THE
APPLICABLE LAW, THAT (I) THE SUIT, ACTION OR PROCEEDING IN SUCH COURTS IS
BROUGHT IN AN INCONVENIENT FORUM, (II) THE VENUE OF SUCH SUIT, ACTION OR
PROCEEDING IS IMPROPER AND (III) THIS AGREEMENT, OR THE SUBJECT MATTER HEREOF,
MAY NOT BE ENFORCED IN OR BY SUCH COURTS.

     SECTION 8.  Amendments; Termination.

     (a) This Agreement may not be modified, amended, altered or supplemented,
except upon the execution and delivery of a written agreement executed by all
parties hereto.

     (b) Except for provisions of this Agreement that by their terms survive the
termination hereof, the provisions of this Agreement shall terminate upon the
earliest to occur of (i) the final adjournment of the 2003 annual meeting of the
stockholders of Daleen and (ii) the termination of the Purchase Agreement in
accordance with its terms.

     SECTION 9.  Additional Shares.  If, after the date hereof, any Stockholder
or Behrman Entity acquires beneficial or record ownership of any additional
shares of capital stock of Daleen (any such shares, "Additional Shares"),
including, without limitation, upon exercise of any option, warrant or right to
acquire shares of capital stock of Daleen or through any stock dividend or stock
split, the provisions of this Agreement applicable to the Shares shall
thereafter be applicable to such Additional Shares as if such Additional Shares
had been Shares as of the date hereof. The provisions of the immediately
preceding sentence shall be effective with respect to Additional Shares without
action by any person or entity immediately upon the acquisition by any
Stockholder of beneficial ownership of such Additional Shares.

     SECTION 10.  Successors and Assigns.  The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective legal successors (including, in the case of any individual
Stockholder, any Behrman Entity or any other individual, any executors,
administrators, estates, legal representatives and heirs of such Stockholder,
Behrman Entity or such individual) and permitted assigns; provided, however,
that, except as otherwise provided in this Agreement, no party may assign,
delegate or otherwise transfer any of its rights or obligations, under this
Agreement, without (a) the consent of the Behrman Entities, in the case of any
Stockholder, or (b) the consent of the HarbourVest Funds, in the case of the
Behrman Entities. Without limiting the scope or effect of the restrictions on
Transfer set forth in Section 2, each Stockholder and each Behrman Entity agrees
that this Agreement and the obligations hereunder shall attach to the Shares and
shall be binding upon any person or entity to which legal or beneficial
ownership of such Shares shall pass, whether by operation of law or otherwise.

     SECTION 12.  Counterparts.  This Agreement may be executed in any number of
counterparts, all of which, when taken together, shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party. The parties also expressly agree
that this Agreement may be executed by original signatures delivered by
facsimile.
