         SECURITIES PURCHASE AGREEMENT, dated as of March 30, 2001 (this
"AGREEMENT"), between DALEEN TECHNOLOGIES, INC., a Delaware corporation (the
"COMPANY"), and the purchasers identified in Exhibit A to this Agreement (each
individually an "ESCROW PURCHASER," and collectively the "ESCROW PURCHASERS").

                                    RECITALS

         A.       Upon and subject to the terms and conditions set forth in this
Agreement, the Company proposes to issue and sell to the Escrow Purchasers, and
the Escrow Purchasers desire to purchase from the Company (i) an aggregate of
247,882 shares, par value $.01 per share, of Series F Convertible Preferred
Stock of the Company (the "SERIES F PREFERRED"), and (ii) warrants
(collectively, the "ESCROW WARRANTS") to purchase, subject to the terms and
conditions thereof, an aggregate of 99,153 shares of Series F Preferred at an
exercise price of $166.41 per share, containing the terms and conditions set
forth in the form of warrant attached hereto as Exhibit B.

         B.       Each share of Series F Preferred is convertible into shares of
common stock, par value $.01 per share, of the Company (the "COMMON STOCK").

         C.       The Company and the Escrow Purchasers are executing and
delivering this Agreement in reliance upon the exemption from securities
registration afforded by Rule 506 of Regulation D ("REGULATION D") as
promulgated by the United States Securities and Exchange Commission (the "SEC")
under the Securities Act of 1933, as amended (the "SECURITIES ACT").

         D.       Contemporaneously with the execution and delivery of this
Agreement, the parties hereto are executing and delivering a Registration Rights
Agreement substantially in the form attached hereto as Exhibit C (the
"REGISTRATION RIGHTS AGREEMENT") pursuant to which the Company has agreed to
provide certain registration rights under the Securities Act, and the rules and
regulations promulgated thereunder, and applicable state securities laws.

         E.       Pursuant to the MarketPlace Rules of the Nasdaq National
Market (the "NNM"), and the Delaware General Corporation Law, the Company is
required to obtain common stockholder approval for the issuance and sale of
Series F Preferred and Escrow Warrants and the other transactions contemplated
by the Transaction Documents (as hereinafter defined) (i) to the extent such
shares of Series F Preferred and Warrant Shares (as defined herein) are
convertible into a number of shares of Common Stock equal to 20% or more of the
outstanding shares of Common Stock on the date hereof, (ii) to certain
affiliates of the Company and (iii) to the extent that the issuance and sale of
the Series F Preferred and Escrow Warrants constitute a change of control under
the MarketPlace Rules. Additionally, the Company will be required to obtain
stockholder approval of an amendment to the Company's Certificate of
Incorporation (i) to the

total number of authorized shares of capital stock to 221,877,236 and to
increase to 200,000,000 the total number of shares of Common Stock authorized to

"CERTIFICATE OF AMENDMENT", and the stockholder approval of the Certificate of
Amendment together with the stockholder approval required by the MarketPlace
Rules of The Nasdaq National Market, hereinafter are referred to collectively as
the "REQUISITE STOCKHOLDER APPROVAL"). As a result, contemporaneously with the
execution and delivery of this Agreement, the Company, the Escrow Purchasers and
SunTrust Bank, a Georgia banking corporation, as escrow agent (the "ESCROW

hereto as Exhibit D (the "ESCROW AGREEMENT") pursuant to which the Purchase
Price (as hereinafter defined) payable by the Escrow Purchasers for the Escrow

pending the Company's receipt of the Requisite Stockholder Approval.

         IN CONSIDERATION of the mutual covenants and agreements set forth

acknowledged, the parties agree as follows:

Warrants to purchase the aggregate number of shares of Series F Preferred in the
respective amounts set forth opposite each Escrow Purchaser's name on Exhibit A

writing (the "APPROVAL DATE"), the Company's obligation to sell, and the Escrow

Escrow Purchasers agree to use the fair market value as so determined for U.S.
federal tax purposes with respect to the transactions contemplated by this
Agreement (unless otherwise required by final determination by the Internal
Revenue Service or a court of competent jurisdiction); provided, however, that
the fair market value of the Escrow Warrants for purposes of financial reporting
shall be in accordance with generally accepted accounting principles
consistently applied ("GAAP").

the Escrow Warrants and the issuance of the Warrant Shares upon exercise of the
Escrow Warrants and the issuance of the Common Stock issuable upon conversion of
the Escrow Shares and the Warrant Shares, in each case in accordance with the

provisions under, any term or provision of any state or Federal law, ordinance,
rule or regulation to which the Company is subject, or the Company's Certificate
of Incorporation or Bylaws, as amended and in effect on the date hereof, or any
mortgage, indenture, agreement, instrument, judgment, decree, order or other

stockholder has any preemptive right or rights of first refusal by reason of the
issuance of the Escrow Shares or Escrow Warrants. The Escrow Shares, when issued
in compliance with the provisions of this Agreement, and the Warrant Shares,

authorized and validly reserved, will not be subject to any preemptive rights or
rights of first refusal and, upon issuance in accordance with the terms of the
Escrow Warrants and the Escrow Shares, as the case may be, will be validly
issued, fully paid and nonassessable.

extent that the failure to file or pay, or such returns are not true and correct

Company). The Company has withheld or collected from each payment made to each
of its employees the amount of all taxes, including, but not limited to, federal
income taxes, Federal Insurance Contribution Act taxes and Federal Unemployment
Tax Act taxes required to be withheld or collected therefrom, and has paid the
same to the proper tax receiving officers or authorized depositories. The
Company knows of (i) no other tax returns or reports which were previously
required to be filed which have not been so filed (ii) no audits that have been
or being currently audited on any of its returns as of the date hereof and (iii)
no unpaid assessment for additional taxes for any fiscal period or any basis
therefor, except to the extent that the failure to file or pay would not have a
material adverse effect, on the conditions or operations of the Company. The
Company's federal income tax returns have not been audited by the Internal
Revenue Service.

                  (k)      Employee Benefits; ERISA. (i) With respect to each
employee benefit plan (as such term is defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")) (an "EMPLOYEE
BENEFIT PLAN") maintained by the Company or an "ERISA Affiliate" (as defined
below): (A) such plan has been administered and operated in compliance with its
terms and the applicable requirements of ERISA and the Internal Revenue Code of
1986, as amended (the "CODE"); (B) to the knowledge of the Company no event has
occurred and there exists no circumstance under which the Company could
reasonably be expected to incur liability under ERISA or the Code (other than
for contributions or benefits paid or payable in the ordinary course of
operation of such plan); (C) there are no actions, suits or claims pending or
threatened with respect to any Employee Benefit Plan or against the assets or a
fiduciary of any Employee Benefit Plan; (D) no "prohibited transaction" (as
defined in Section 406 of ERISA or Section 4975 of the Code) which is not
covered by an applicable exemption has occurred; (E) no "reportable event" (as
defined in Section 4043 of ERISA) has occurred; (F) all contributions and
premiums due have been paid on a timely basis; and (G) all contributions made
under any Employee Benefit Plan intended to be tax deductible meet the
requirements for deductibility under the Code, except, in the case of each of
clauses (A) through (G), as would not have a material adverse effect on the
Company. As used herein, the term "ERISA Affiliate" refers to any organization
that is (x) a member of a "controlled group" of which the Company is a member or
(y) under "common control" with the Company within the meaning of Section 414(b)
and (c) of the Code.

                           (ii)     Each Employee Benefit Plan maintained by the
Company or an ERISA Affiliate that is intended to qualify under Section 401(a)
of the Code has received a favorable letter of determination from the Internal
Revenue Service that it so qualifies and that its related trust is exempt from
taxation under Section 501(a) of the Code. No event has occurred that will or
could reasonably be expected to give rise to disqualification or loss of
tax-exempt status of any such Employee Benefit Plan or trust under Sections
401(a) or 501(a) of the Code.

                           (iii)    No Company or ERISA Affiliate benefit plan
is a "defined benefit plan" within the meaning of Section 3(35) of ERISA, a
"multiemployer plan" within the meaning of Section 3(37) of ERISA, or a
"multiple employer plan" within the meaning of Section 413 of the Code.

                           (ii)     Loan or other agreements, notes, indentures,
or instruments relating to or evidencing indebtedness for borrowed money, or

Company or its Subsidiaries is or, to the Company's knowledge, may be named as a
party or its property is or may be subject and in which an unfavorable outcome,
ruling or finding in any such matter or for all such matters taken as a whole

or operations of the Company and its Subsidiaries taken as a whole; and the
Company has no knowledge of any unasserted claim, the assertion of which is
reasonably likely and which, if asserted, will seek damages, an injunction or

of the Company and its Subsidiaries taken as a whole.

contesting each of the Company and its Subsidiaries right to develop, produce,
manufacture, license, lease, sell or use any product, process, method,
substance, part or other material presently developed, produced, manufactured,
licensed, leased, sold or used or planned to be developed, produced,
manufactured, licensed, leased, sold or used by the Company and its Subsidiaries
in connection with the operations of the Company, except for claims if

and its Subsidiaries has all franchises, permits, licenses and other similar
authority necessary for the conduct of its business as now being conducted by it
and as planned to be conducted, the lack of which could materially and adversely
affect the operations or condition, financial or otherwise, of the Company and
neither the Company nor its Subsidiaries is in default in any material respect
under any of such franchises, permits, licenses or other similar authority. The
Company and its Subsidiaries are the exclusive owner of all right, title and
interest in and or has the valid and legal right to use all Intellectual

infringement upon any valid rights of others, in each case, except as would not

otherwise, of the Company and its Subsidiaries taken as a whole. Neither the
Company nor any of its Subsidiaries have received any notice that the conduct of
its business infringes upon or conflicts with the asserted rights of others and

asserted rights in any material respect.

Subsidiaries who develops or has access to Intellectual Property and proprietary
information of the Company and its Subsidiaries has executed and delivered to
the Company a proprietary information and inventions agreement substantially in

                  (u)      Offering. Subject to the accuracy of the
representations and warranties of each Escrow Purchaser set forth in Section 2.2
hereto, the offer, issuance and sale of the Escrow Shares and Escrow Warrants as
contemplated by this Agreement are exempt from the registration requirements of
the Securities Act, and from any registration or filing requirements of any
applicable state securities laws, and neither the Company nor anyone acting on
its behalf will take any action hereafter that would reasonably be expected to
cause the loss of such exemption.

                  (v)      Compliance with Other Instruments. The Company and
its Subsidiaries are not in violation of any term of each of its respective
Certificate of Incorporation or Bylaws, in each case, as in effect on the date
hereof. The Company and its Subsidiaries are not (and, upon receipt by the
Company of the Requisite Stockholder Approval, consummation of the transactions
contemplated by the Transaction Documents will not cause the Company and its
Subsidiaries to be) in violation of any term of any mortgage, indenture,
contract, agreement, instrument, judgment, decree, order, statute, rule or
regulation to which the Company and its Subsidiaries are subject and a violation
of which would have a material adverse effect on the condition, financial or
otherwise, or operations of the Company and its Subsidiaries when taken as a
whole.

                  (w)      Employees. To the Company's knowledge, no employee of

hereafter be issued and all corporate activities on the part of the Company have
been taken with respect to the registration rights in the Transaction Documents
and as set forth in Schedule 2.1(x) of the Schedule of Exceptions, so that the
execution and performance of the Transaction Documents by the Company will not
cause a conflict with, or result in a breach of, or constitute a default under
an existing agreement or obligation of the Company with respect to registration
rights as set forth herein.

                  (y)      Environmental and Safety Laws. Neither the Company
nor any of its Subsidiaries is in violation of any applicable statute, law or

in order to comply with any such existing statute, law or regulation.

                  (z)      Disclosure. The Transaction Documents and the
Schedule of Exceptions as read together do not contain any untrue statement of a
material fact and do not omit to state a material fact necessary in order to
make the statements contained therein or herein not misleading. Furthermore, the

defined herein) (A) were prepared in accordance with the requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and (B) did
not at the time they were filed (or if amended or superseded by a filing prior

                  (a)      Organization; Authority. Such Escrow Purchaser is an
individual or is a corporation or other entity duly incorporated or organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation or organization with the requisite corporate or other power and
authority to enter into and to consummate the transactions contemplated by the
Transaction Documents and otherwise to carry out its obligations thereunder. The
purchase by such Escrow Purchaser of the Escrow Shares and the Escrow Warrants
hereunder has been duly authorized by all necessary action on the part of such
Escrow Purchaser. Each of the Transaction Documents to be executed by the Escrow
Purchaser pursuant to the terms hereof or thereof has been duly executed and
delivered by such Escrow Purchaser and constitutes the valid and legally binding
obligation of such Escrow Purchaser, enforceable against such Escrow Purchaser,
in accordance with its terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights generally and to general principles
of equity.

                  (b)      Investment Intent. Such Escrow Purchaser is acquiring
the Escrow Shares and Escrow Warrants, and upon conversion of the Escrow Shares
and Warrant Shares or exercise of the Escrow Warrants, will acquire the Series F
Preferred or Common Stock, as the case may be, for its own account for
investment only and not with a view towards, or for resale in connection with,
the public sale or distribution thereof, except pursuant to sales registered or
exempted under the Securities Act; provided, however, that by making the
representations contained in this Section 2.2(b), such Escrow Purchaser does not
agree to hold any of the Series F Preferred, Warrant Shares or Common Stock for
any minimum or other specific term and


                                      -17-
<PAGE>   18

reserves the right to dispose of such securities at any time in accordance
with or to the extent allowed by this Agreement, the Registration Rights
Agreement and the Securities Act.

                  (c)      Accredited Investor. At the time such Escrow
Purchaser was offered the Series F Preferred and the Escrow Warrant, it was, and
at the date hereof, it is, and at the Escrow Closing and each of its conversion
dates as to the Series F Preferred or exercise dates as to the Escrow Warrants,
it will be, an "accredited investor" as defined in Rule 501(a) under the
Securities Act.

                  (d)      Experience of Escrow Purchaser. Such Escrow Purchaser
either alone or together with its representatives, has such knowledge,
sophistication and experience in business and financial matters so as to be

Securities, and has so evaluated the merits and risks of such investment.

                  (e)      Ability of Escrow Purchaser to Bear Risk of
Investment. Such Escrow Purchaser acknowledges that the Series F Preferred,
Escrow Warrants, Warrant Shares, and Common Stock are speculative investments
and may involve a high degree of risk and such Escrow Purchaser is able to bear
the economic risk of an investment in the Escrow Shares and the Escrow Warrants,
and, at the present time, is able to afford a complete loss of such investment.

                  (f)      Access to Information. Such Escrow Purchaser
acknowledges receipt of the Schedule of Exceptions and further acknowledges that
it has been afforded (i) the opportunity to ask such questions as it has deemed
necessary of, and to receive answers from, representatives of the Company
concerning the terms and conditions of the offering of the Series F Preferred
and the Escrow Warrants, and the merits and risks of investing in the Series F
Preferred and the Escrow Warrants; (ii) access to information about the Company
and the Company's financial condition, results of operations, business,
properties, management and prospects sufficient to enable it to evaluate its
investment; and (iii) the opportunity to obtain such additional information
which the Company possesses or can acquire without unreasonable effort or
expense that is necessary or advisable to make an informed investment decision
with respect to the investment and to verify the accuracy and completeness of
the information contained in the Schedule of Exceptions.

                  (g)      Affiliate Status. Other than HarbourVest Partners VI
- Direct Fund L.P., SAIC Venture Capital Corporation and Paul Cataford, on the

                  (i)      Transfer or Resale. Such Escrow Purchaser understands
that except as provided in the Registration Rights Agreement: (i) the Escrow
Shares and the Escrow Warrants have not been and are not being registered under
the Securities Act or any state securities laws, and may not be offered for
sale, sold, assigned or transferred unless (A) subsequently registered under the
Securities Act and applicable state securities laws, (B) such Escrow Purchaser
shall have delivered to the Company an opinion of counsel, in a generally
acceptable form, to the effect that such Escrow Shares and the Escrow Warrants
to be sold, assigned or transferred may be sold, assigned or transferred
pursuant to an exemption from such registration, (C) such Escrow Purchaser
provides the Company with reasonable assurance that such Escrow Shares and the
Escrow Warrants can be sold, assigned or transferred pursuant to Rule 144
promulgated under the Securities Act (or a successor rule thereto) ("RULE 144")
or (D) transferred in accordance with Rule 144A under the Securities Act (or any
successor rule thereto) ("RULE 144A") to a qualified institutional buyer (as
such term is defined in Rule 144A(a)(1)); (ii) any sale of the Escrow Shares and
the Escrow Warrants made in reliance on Rule 144 may be made only in accordance
with the terms of Rule 144 and further, if Rule 144 is not applicable, any
resale of the Escrow Shares and the Escrow Warrants under circumstances in which
the seller (or the person through whom the sale is made) may be deemed to be an
underwriter (as that term is defined in the Securities Act) may require
compliance with some other exemption under the Securities Act or the rules and
regulations of the SEC thereunder; and (iii) neither the Company nor any other
person is under any obligation to register such Escrow Shares and the Escrow
Warrants under the Securities Act or any state securities laws or to comply with
the terms and conditions of any exemption thereunder.

                  (j)      Legends. Such Escrow Purchaser understands that the
certificates or other instruments representing the Escrow Shares, the Escrow
Warrants, the Warrant Shares, and, until such time that the Common Stock
issuable upon conversion of the Escrow Shares and the Warrant Shares has been
registered under the Securities Act as contemplated by the Registration Rights
Agreement, the stock certificates representing the Escrow Shares, the Escrow
Warrants, the Warrant Shares, except as set forth below, shall bear a
restrictive legend in substantially the following form (and a stop-transfer
order may be placed against transfer of such stock certificates):

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
         SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD,
         TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
         STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS
         AMENDED, OR APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL,
         IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER
         SAID ACT OR APPLICABLE STATE SECURITIES LAWS OR (II) UNLESS SOLD
         PURSUANT TO EITHER RULE 144A UNDER SAID ACT TO A QUALIFIED
         INSTITUTIONAL BUYER OR RULE 144 UNDER SAID ACT.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped, if (i) such Securities are registered for sale under the Securities
Act, or (ii) in connection with a sale transaction, such holder provides the
Company with an opinion of counsel, in a generally acceptable form to the
Company, to the effect that a public sale, assignment or transfer of such
Securities may be made without registration under the Securities Act. Such
Escrow Purchaser acknowledges, covenants and agrees to sell the Securities
represented by a certificate(s) from which the legend has been removed, only
pursuant to (i) a registration statement effective under the Securities Act and
upon compliance with the prospectus delivery requirements of the Securities Act,
or (ii) advice of counsel that such sale is exempt from registration required by
Section 5 of the Securities Act; and

                  (k)      Reliance. Such Escrow Purchaser understands and
acknowledges that (i) the Escrow Shares and the Escrow Warrants are being, and
upon conversion of the Series F Preferred and the Warrant Shares, the underlying
Common Stock and upon exercise of the Escrow Warrants, the Warrant Shares will
be, offered and sold to such Escrow Purchaser without registration under the
Securities Act in a private placement that is exempt from the registration
provisions of the Securities Act and (ii) the availability of such exemption,
depends in part on, and the Company will rely upon, the accuracy and
truthfulness of, the foregoing representations and the Escrow Purchaser hereby
consents to such reliance.

                                   ARTICLE III

                         OTHER AGREEMENTS OF THE PARTIES

         3.1      Form D and Blue Sky. The Company agrees to file a Form D with
respect to the Securities as required under Regulation D under the Securities
Act within the time specified in Regulation D and to provide a copy thereof to
each Escrow Purchaser promptly after such filing. The Company shall, on or
before the Closing Date, take such action as the Company shall reasonably
determine is necessary to qualify the Securities for, or obtain exemption for
the Securities for, sale to the Escrow Purchasers at the Escrow Closing pursuant
to this Agreement under applicable state securities laws, and shall provide
evidence of any such action so taken to the Escrow Purchasers on or prior to the
Escrow Closing or, if later, the date by which such action must be taken. The
Company shall make all filings and reports relating to the offer and sale of the
Securities required under applicable state securities laws following the Escrow
Closing.

         3.2      Reporting Status. Until the earlier of (i) the date which is
one year after the date on which the holders thereof may sell all of the Common
Stock issuable upon conversion of the Escrow Shares and the Warrant Shares

successor thereto) and (ii) the date on which (A) the holders thereof shall have
sold all the Common Stock issuable upon conversion of the Escrow Shares and the

<PAGE>   21

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

         3.3      Stockholder Information. The Company agrees to send to each
Escrow Purchaser during the Reporting Period copies of any notices and other
information made available or given to the stockholders of the Company
generally, contemporaneously with the making available or giving thereof to the
stockholders. During the Reporting Period, the Company shall include each Escrow
Purchaser on the Company's distribution list for press releases and shall
provide each Escrow Purchaser with any such press releases in the same manner
and at the same time as others on such distribution list.

         3.4      Listing. Following the Escrow Closing, the Company shall
promptly secure the listing of all of the Registrable Securities (as defined in
the Registration Rights Agreement) upon each national securities exchange and
automated quotation system (including NNM), if any, upon which shares of Common
Stock are then listed (subject to official notice of issuance) and shall
maintain, so long as any other shares of Common Stock shall be so listed, such
listing of all Registrable Securities from time to time issuable under the terms
of the Transaction Documents. During the Reporting Period, the Company shall use
its reasonable best efforts to maintain the Common Stock's listing on either the
NNM, a national exchange or other market or interdealer quotation system
(including without limitation the Nasdaq SmallCap Market and the OTC Bulletin
Board). The Company shall promptly provide the Escrow Purchasers copies of any
notices it receives from the NNM regarding the continued eligibility of the
Common Stock for listing on such automated quotation system or securities
exchange, provided that the Company shall not be required to provide such
notices if the Company reasonably determines that such notices contain material
non-public information. The Company shall pay all fees and expenses in
connection with satisfying its obligations under this Section 3.4.

         3.5      Expenses. At the Initial Closing, the Company shall pay the
fees of (i) O'Melveny & Myers LLP as counsel for certain of the Escrow
Purchasers and the Placement Agent and (ii) Debevoise & Plimpton as counsel to
certain of the Escrow Purchasers, solely with respect to fees related to the
negotiation and execution of the Transaction Documents and the Initial Closing,
provided that such counsel shall provide to the Company a full accounting of
such expenses, including the submission of invoices or statements for such
expenses.

         3.6      Trading Restrictions. Each Escrow Purchaser agrees that during
the ten (10) trading days immediately preceding the Initial Closing Date, it
shall not sell any shares of Common Stock including by way of any "short sales"
of the Common Stock (as defined in Rule 3b-3 of the Exchange Act). Additionally,
each Escrow Purchaser agrees that during the ten (10) trading days following
each Earnings Release (as defined in the Certificate of Amendment), it shall not
sell any shares of Common Stock including by way of any "short sales" of the
Common Stock (as defined in Rule 3b-3 of the Exchange Act).

         3.7      Transfer Agent Instructions. The Company shall issue
instructions to its transfer agent, and any subsequent transfer agent, to issue
certificates, registered in the name of each Escrow Purchaser or its nominee(s),
for the Common Stock issuable upon conversion of the Escrow Shares or the
exercise of the Escrow Warrants in such amounts as specified from time to time
by each Escrow Purchaser to the Company upon such conversion or exercise as the
case may be (the "TRANSFER AGENT INSTRUCTIONS"). Nothing in this Section 3.7
shall affect in any way each Escrow Purchaser's obligations under the Securities
Act and agreements set forth in Section 2.2(i) herein to comply with all
applicable prospectus delivery requirements, if any, upon resale of the
Securities.

         3.8      Requisite Stockholder Approval and Waiver. (a) As soon as
possible after the date hereof but in no event later than the Approval Date, the
Company shall convene a meeting of stockholders for the purpose of obtaining the
Requisite Stockholder Approval, including any and all approvals required by the
applicable policies, rules or regulations of NNM, to approve the transactions
contemplated hereby.

         (b)      Each of the Escrow Purchasers hereby irrevocably agrees (i) to
vote all of such Escrow Purchaser's shares of Common Stock, whether now owned or
hereafter acquired, in favor of the transactions contemplated hereby in
connection with the Requisite Stockholder Approval, including without limitation
in favor of the issuance and sale to the Escrow Purchasers of the Escrow Shares
and Escrow Warrants and the other transactions contemplated by the Transaction
Documents, and in favor of an amendment to the Company's Certificate of
Incorporation to increase the total number of authorized shares of stock to
221,877,236 shares and the total number of authorized shares of Common Stock to
200,000,000 shares and in favor of an amendment to the Company's Certificate of
Incorporation to authorize, designate and create the Series F Preferred, and
(ii) shall take no action whatsoever to agree to revoke or cause to revoke the
letter agreements referred to in Section 4.1(h) herein, or take any action the
result of which would be to prevent such Escrow Purchaser from effecting the
agreement set forth in this Section 3.8(b). Additionally, each of the Escrow
Purchasers agrees not to sell, transfer or otherwise dispose of, or transfer the
voting rights with respect to its shares of the Company's Common Stock or on or
prior to the Approval Date set forth in this Section 3.8(b).

         (c)      The Company shall bear all expenses in connection with the
holding of such meeting, including the costs and expenses of the preparation,
filing and distribution of the proxy statement.

         3.9      Modification to and Filing Certificate of Amendment. Following
the receipt of the Requisite Stockholder Approval but prior to the Escrow
Closing, the Company shall have duly filed the Certificate of Amendment with the
Secretary of State of the State of Delaware in accordance with the General
Corporate Law of the State of Delaware. In the event that at any time after the
date hereof but prior to the filing of the Certificate of Amendment, the Company
takes any of the actions described in Sections 6(e)(ii), (iii) and (iv) of the
Certificate of Amendment, then prior to the filing of the Certificate of
Amendment, the Conversion Price set forth in Section 6(c) of the Certificate of
Amendment shall be adjusted to the Conversion Price


                                      -22-
<PAGE>   23

that would have been in effect had the Certificate of Amendment been filed with
the Secretary of State of Delaware and effective immediately prior to the
Company taking such actions. Notwithstanding any other provision of this
Agreement, the provisions of this Section 3.9 may be waived by the Escrow
Purchasers who have agreed herein to purchase a majority of the Escrow Shares
(as reflected on Exhibit A hereto).

         3.10     Conduct of Business. Except as required by this Agreement or
as is necessary to consummate the transactions contemplated hereby, the Company
will not authorize for issuance, issue, sell, deliver or agree or commit to
issue, sell or deliver (whether through the issuance or granting of options,
warrants, commitments, subscriptions, rights to purchase or otherwise) any
Series F Preferred.

         3.11     Books and Records. The Company shall keep proper books of
record and account, in which full and correct entries shall be made of all
financial transactions and the assets and business of the Company in accordance
with generally accepted accounting principles consistently applied.

         3.12     Inspection. The Company shall permit representatives of the
Escrow Purchasers to visit and inspect any of its properties, to examine its
corporate, financial and operating records and make copies thereof or abstracts
therefrom, and to discuss its affairs, finances and accounts with their
respective directors, officers and independent public accountants, all at such
reasonable times during normal business hours and as often as may be reasonably
requested upon reasonable advance notice to the Company (such rights to visit,
inspect, examine, make copies and discuss are collectively referred to as
"INSPECTION RIGHTS"); provided, however, that no such inspection, examination or
inquiry, the failure to conduct same, nor any knowledge of any Escrow Purchaser,
including any knowledge obtained by such Escrow Purchaser in connection with any
such inspection, investigation or inquiry, shall constitute a waiver of any
rights Escrow Purchasers may have under any representation, warranty, covenant,
term or agreement under any of the Transaction Documents. Notwithstanding the
foregoing, the Company shall not be required to permit representatives of the
Escrow Purchasers to exercise their Inspection Rights until such time as the
Escrow Purchaser(s) exercising its rights, and its representatives, shall have
executed a confidentiality and non-disclosure agreement in form and substance
reasonably satisfactory to the Company and which permits the Company to provide
to such Escrow Purchaser(s) or its representatives material non-public
information without violation of Regulation FD promulgated by the SEC. During
all periods when an Escrow Purchaser is in possession of material non-public
information obtained pursuant to its Inspection Rights, the Escrow Purchaser
agrees that it will not trade in the securities of the Company until such time
as the Company has publicly disclosed such material non-public information in a
manner contemplated by Regulation FD.

any other jurisdictions) that would cause the application of the laws of any
jurisdictions other than the State of New York.

         5.9      Survival. The agreements and covenants contained in Article IV
and this Article V shall survive the delivery and conversion of the Escrow
Shares pursuant to this Agreement, and the representations and warranties of the
Company and the Escrow Purchasers contained in Article II shall survive until a
date that is three years after the Closing Date.

         5.10     Execution. 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, it being understood that both
parties need not sign the same counterpart. The parties also expressly agree
that this Agreement may be executed by original signatures delivered by
facsimile.

         5.11     Publicity. The Company and the Escrow Purchasers shall consult
with each other in issuing any press releases or otherwise making public
statements with respect to the transactions contemplated hereby and neither
party shall issue any such press release or otherwise make any such public
statement without the prior written consent of the other, which consent shall
not be unreasonably withheld or delayed, except that no prior consent shall be
required if (a) such disclosure is required by law, in which case the disclosing
party shall provide the other party with prior notice of such public statement
or (b) such information is already publicly available. Notwithstanding the
generality of the foregoing, the parties agree that the Company will issue a
press release at or immediately after the Initial Closing, the contents of
which, together with all documents required to be filed therewith, will be filed
with the SEC as a current report of the Company on Form 8-K, the form of which
will be agreed to by the parties at or before the issuance thereof.

         5.12     Severability. In case any one or more of the provisions of
this Agreement shall be invalid or unenforceable in any respect, the validity
and enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affected or impaired thereby and the parties will attempt to
agree upon a valid and enforceable provision which shall be a reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

         5.13     No Strict Construction. The language used in this Agreement
will be deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any party.
