                          SECURITIES PURCHASE AGREEMENT

as of March 28, 2002, by and among Centiv, Inc., a Georgia corporation (the
"Company"), and the purchasers identified on Exhibit A to this Agreement (the

        A. Each Purchaser desires to purchase units ("Units") from the Company,

one Unit shall be $10.00 (the "Purchase Price"). The shares of Preferred Stock
are convertible into shares of the Company's Class A Common Stock, $.001 per
share ("Common Stock") in accordance with the Certificate of Designations. The

a Purchaser.

        B. In connection with the purchase and sale of the Units, the parties to
this Agreement are entering into an Investor Rights Agreement in the form
attached to this Agreement as Exhibit D (the "Investor Rights Agreement"),

of Purchasers includes all shares of Common Stock then held or acquirable by
such Purchaser or group of Purchasers that were acquired or are acquirable (a)
directly upon exercise of outstanding Warrants and (b) upon conversion of shares
of Preferred Stock, regardless of whether such Preferred Stock was acquired
under this Agreement or was acquired or is acquirable upon exercise of Warrants.

        "CONVERSION SHARES" shall mean the shares of Common Stock issuable upon
conversion of the Preferred Stock.

        "INVESTMENT AMOUNT" shall mean the dollar amount to be invested in the

3.   THE PURCHASER'S REPRESENTATIONS AND WARRANTIES.

        Each Purchaser severally and not jointly represents and warrants to the
Company as follows:

        3.1 PURCHASE FOR OWN ACCOUNT. The Purchaser is purchasing the Securities
for the Purchaser's own account and not with a present view towards the
distribution thereof. The Purchaser understands that the Purchaser must bear the
economic risk of this investment indefinitely, unless the Securities are
registered pursuant to the Securities Act of 1933, as amended (the "Securities
Act"), and any applicable state securities or blue sky laws or an exemption from
such registration is available, and that the Company has no present intention of
registering any such Securities other than as contemplated by the Investor
Rights Agreement. Notwithstanding anything in this Section 3.1 to the contrary,
by making the foregoing representation, the Purchaser does not agree to hold the
Securities for any minimum or other specific term and reserves the right to
dispose of the Securities at any time in accordance with or pursuant to a
registration statement or an exemption from registration under the Securities
Act and any applicable state securities laws.

        3.2 INFORMATION. The Purchaser has been furnished all materials relating
to the business, finances and operations of the Company and its subsidiaries and
materials relating to the offer and sale of the Securities which have been
requested by the Purchaser. The Purchaser has been afforded the opportunity to
ask questions of the Company and has received satisfactory answers to any such
inquiries. Neither such inquiries nor any other due diligence investigation
conducted by the Purchaser or its counsel or any of its representatives shall
modify, amend or affect the Purchaser's right to rely on the Company's
representations and warranties contained in Section 4 below.

                                        2
<Page>

        3.3 GOVERNMENTAL REVIEW. The Purchaser understands that no United States
federal or state agency or any other government or governmental agency has
passed upon or made any recommendation or endorsement of the Securities.

        3.4 AUTHORIZATION; ENFORCEMENT. The Purchaser has the requisite power
and authority to enter into and perform its obligations under this Agreement and
to purchase the Units in accordance with the terms hereof. This Agreement has
been duly and validly authorized, executed and delivered on behalf of the
Purchaser and is a valid and binding agreement of the Purchaser enforceable
against the Purchaser in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
other laws affecting creditors' rights and remedies generally and to general
principles of equity (regardless of whether enforcement is sought in a
proceeding at law or in equity).

        3.5 TRANSFER OR RESALE. The Purchaser understands that (i) except as
provided in the Investor Rights Agreement, the Securities have not been and are
not being registered under the Securities Act or any state securities laws, and
may not be transferred unless (a) subsequently registered thereunder, (b) the
Purchaser shall have delivered to the Company an opinion of counsel reasonably
acceptable to the Company (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions) to the effect that
the Securities to be sold or transferred may be sold or transferred under an
exemption from such registration, (c) sold under Rule 144 promulgated under the
Securities Act (or a successor rule), or (d) sold or transferred to an affiliate
of the Purchaser pursuant to an exemption under the Securities Act; and (ii)
neither the Company nor any other person is under any obligation to register
such Securities under the Securities Act or any state securities laws or to
comply with the terms and conditions of any exemption thereunder, in each case,
other than pursuant to the Investor Rights Agreement.

        3.6. LEGENDS. The Purchaser understands that the Shares, the shares of
Preferred Stock issuable upon Warrant exercise and the Warrants and, until such
time as the Conversion Shares and shares of Common Stock issuable directly upon
exercise of the Warrants have been registered under the Securities Act as
contemplated by the Investor Rights Agreement or otherwise may be sold by the
Purchaser under Rule 144, the certificates for such Conversion Shares and other
shares of Common Stock may bear a restrictive legend in substantially the
following form:

        "The securities represented by this certificate have not been registered
        under the Securities Act of 1933, as amended, or the securities laws of
        any state of the United States. The securities represented hereby may
        not be offered or sold in the absence of an effective registration
        statement for the securities under applicable securities laws unless
        offered, sold or transferred under an available exemption from the
        registration requirements of those laws. "

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of any Security upon which it is
stamped, if, (a) the sale of such Security is registered under the Securities
Act, (b) such holder provides the Company with an opinion of counsel, in form,
substance and scope customary for opinions of counsel in comparable
transactions, to the effect that a public sale or transfer of such Security may
be made without registration under the Securities Act or (c) such holder
provides the Company with reasonable assurances that such Security can be sold
under Rule 144(k). The Purchaser agrees to sell all Securities, including those
represented by a certificate(s) from which the legend has been removed, pursuant
to an effective registration statement or under an exemption from the
registration requirements of the Securities Act. In consideration of such
removal, the Purchaser agrees and covenants that in connection with the
registration of such Securities, it will sell all Securities in accordance with
the plan of distribution contained in the registration statement pursuant to
which it is selling its Securities, it will deliver a prospectus in accordance
with the prospectus delivery requirements of the Securities Act, and in the
event that the Company informs such Purchaser that the registration statement
has ceased to be effective under the Securities Act, such Purchaser shall, at
the request of the Company, return its Securities for legending unless at such
time such Securities may be sold under Rule 144(k).

        3.7 ACCREDITED INVESTOR STATUS. The Purchaser is an "accredited
investor" as that term is defined in Rule 501(a) of Regulation D promulgated by
the Securities and Exchange Commission ("SEC") under the Securities Act
("Regulation D").

                                        3

being offered and sold and the Warrants are being issued to it in reliance on
specific exemptions from the registration requirements of United States federal
and state securities laws and that the Company is relying upon the truth and
accuracy of, and the Purchaser's compliance with, the representations,
warranties, agreements, acknowledgments, and understandings of the Purchaser set
forth herein in order to determine the availability of such exemptions and the
eligibility of the Purchaser to acquire the Securities.

misleading. Any statements made in any such SEC Documents that are or were
required to be updated or amended under applicable law have been so updated or
amended. As of their respective dates, the financial statements of the Company
included in the SEC Documents complied in all material respects with applicable
accounting requirements and the published rules and regulations of the SEC
applicable with respect thereto. Such financial statements have been prepared in
accordance with United States generally accepted accounting principles,

otherwise indicated in such financial statements or the notes thereto, or (ii)
in the case of unaudited interim statements, to the extent they may not include
footnotes or may be condensed or summary statements) and fairly present in all
material respects the consolidated financial position of the Company and its
subsidiaries as of the dates thereof and the results of their operations and
cash flows for the periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments). Except as set forth in the
SEC Documents, the Company has no liabilities, contingent or otherwise, other
than (i) liabilities incurred in the ordinary course of business subsequent to
the date of such SEC Documents and (ii) obligations under contracts and
commitments incurred in the ordinary course of business and not required under
generally accepted accounting principles to be reflected in such SEC Documents,
which liabilities and obligations referred to in clauses (i) and (ii),
individually or in the aggregate, would not have a Material Adverse Effect.
Except as disclosed in the SEC Documents, since December 31, 2000, there has
been no change by the Company in the method for which it accounts for revenues
or expenses under generally accepted accounting principles.

        4.7 ABSENCE OF CERTAIN CHANGES. Except as disclosed in the SEC
Documents, since September 30, 2001, there has been no change or development
which individually or in the aggregate has had or could reasonably be expected
to have a Material Adverse Effect.

        4.8 ABSENCE OF LITIGATION. Except as disclosed in the SEC Documents,
there is no action, suit, proceeding, inquiry or investigation before or by any
court, public board, government agency, self-regulatory organization or body
pending or, threatened in writing against or affecting the Company, or any of
its subsidiaries, or any of their directors or officers in their capacities as
such which would reasonably be expected to have a Material Adverse Effect or
which would adversely affect the validity, enforceability of, or the authority
or ability of the Company to perform its obligations under this Agreement
(including the issuance of the Shares and the Warrants), the Certificate of
Designations (including the issuance of the Conversion Shares), the Investor
Rights Agreement, the Warrants (including the issuance of the Warrant Shares) or
any other agreement or document delivered pursuant hereto or thereto.

unpatentable proprietary or confidential information, systems or procedures) and
other similar rights and proprietary knowledge (collectively, "Intangibles")
necessary for the conduct of its business as now being conducted and as proposed
to be conducted. To the knowledge of the Company, after reasonable inquiry,
neither the Company nor any of its subsidiaries is infringing or in conflict
with any other person with respect to any Intangibles which, individually or in
the aggregate, if the subject of an unfavorable decision, ruling or finding,
would have a Material Adverse Effect. Neither the Company nor any of its
subsidiaries has received written notice that it is infringing upon third party
Intangibles. Neither the Company nor any of its subsidiaries has entered into
any consent, indemnification,

                                        6
<Page>

forbearance to sue or settlement agreements with respect to the validity of the
Company's or such subsidiary's ownership or right to use its Intangibles and to
the Company's knowledge, after reasonable inquiry, there is no basis for any
claim relating to any consent, indemnification, forbearance to sue or settlement
agreement with respect to the validity of the Company's or such subsidiary's
ownership or right to use its Intangibles to be successful. The Intangibles are
valid and enforceable, and no registration relating thereto has lapsed, expired
or been abandoned or canceled or is the subject of cancellation or other
adversarial proceedings, and all applications therefor are pending and in good
standing. The Company has complied, in all material respects, with its
contractual obligations relating to the protection of the Intangibles used
pursuant to licenses. To the Company's knowledge, no person is infringing on or
violating the Intangibles owned or used by the Company.

        4.10 FOREIGN CORRUPT PRACTICES. Neither the Company, nor any of its
subsidiaries, nor any director or officer, nor, to the Company's knowledge, any
agent, employee or other person acting on behalf of the Company or any of its

foreign or domestic government official or employee from corporate funds;

liability, affecting any of the properties of the Company or any of its
subsidiaries that, individually or in the aggregate, would have a Material
Adverse Effect and (ii) neither the Company nor any of the subsidiaries has
violated any environmental law applicable to it now or previously in effect,
other than such violations or infringements that, individually or in the
aggregate, have not had and will not have a Material Adverse Effect.

fee simple to all real property and good title to all personal property owned by
it which is material to its business, free and clear of all liens, encumbrances
and defects except for liens to secure the Company's bank lines of credit and
such defects in title that, individually or in the aggregate, could not have a
Material Adverse Effect. Any real property and facilities held under lease by
the Company or any of its subsidiaries are held by the Company or such
subsidiary under valid, subsisting and enforceable leases with such exceptions
which have not had and will not have a Material Adverse Effect.

        4.13 INSURANCE. The Company and its subsidiaries maintain such insurance
relating to their business, operations, assets, key-employees and officers and
directors as is appropriate to their business, assets and operations, in such
amounts and against such risks as are customarily carried and insured against by
owners of comparable businesses, assets and operations, and such insurance
coverages will be continued in full force and effect to and including the
Closing Date other than those insurance coverages in respect of which the
failure to continue in full force and effect could not reasonably be expected to
have a Material Adverse Effect.

        4.14 DISCLOSURE. All information relating to or concerning the Company
