3. Representations and Warranties of the Investors.  Each Investor hereby
   ------------------------------------------------
   represents and warrants that:

   3.1    Authorization.  This Agreement constitutes its valid and legally
          --------------
binding obligation, enforceable in accordance with its terms.

   3.2    Purchase Entirely for Own Account.  This Agreement is made with each
          ----------------------------------
Investor in reliance upon such Investor's representation to the Company, which
by such Investor's execution of this Agreement such Investor hereby confirms,
that the Units to be received by such Investor will be acquired for investment
for such Investor's own account, not as a nominee or agent, and not with a view
to the resale or distribution of any part thereof, and that such Investor has no
present intention of selling, granting any participation in, or otherwise
distributing the same.  By executing this Agreement, each Investor further
represents that such Investor does not have any contract, undertaking, agreement
or arrangement with any person to sell, transfer or grant participation to such
person or to any third person, with respect to any of the Securities.  Each
Investor represents, that such investor has full power and authority to enter
into this Agreement.

   3.3    Disclosure of Information.  Each Investor has received all of the
          --------------------------
information that such investor has requested and believes such investor has
received all of the information such investor considers necessary or appropriate
for deciding whether to purchase the Units.  Each Investor further represents
that such investor has read carefully and understands the information provided
by the Company and has had ample opportunity to ask questions and receive
answers from the Company regarding the terms and conditions of the offering of
the Units.  The foregoing, however, does not limit or modify the representations
and warranties of the Company in Section 2 of this Agreement or the right of the
Investors to rely thereon.

   3.4    Investment Experience.  Each Investor is an investor in securities of
          ----------------------
early stage companies and acknowledges that such investor is able to fend for
himself or herself, can bear the economic risk of the investment in the Units
and has such knowledge and experience in financial or business matters that such
investor is capable of evaluating the merits and risks of the investment in the
Units.

   3.5    Adequate Means.  Each Investor has adequate means of providing for the
          --------------
each Investor's current needs and possible personal contingencies and has no
need for liquidity in this


-------------------------------------------------------------------------------
Information Analysis Incorporated                                        Page 3
-------------------------------------------------------------------------------
<PAGE>

investment and each Investor can bear the economic risk and/or entire loss of
any investment in the Units. Each Investor's commitment to illiquid investments
is reasonable in relation to such investor's needs. All financial information
provided to the Company by each Investor is true and correct.

   3.6    Accredited Investor.  Each Investor, if a United States resident, is
          -------------------
an "accredited investor" within the meaning of Regulation D promulgated under
the Securities Act of 1933, as amended, inasmuch as each Investor is:

      (A) a natural person whose individual net worth, or joint net worth with
          that person's spouse, at the time of purchase exceeds $1,000,000;

      (B) a natural person who had an individual income in excess of $200,000 in
          each of the two most recent years or joint income with that person's
          spouse of $300,000 in each of those years and who has a reasonable
          expectation of reaching the same income level in the current year;

      (C) an organization described in section 501(c)(3) of the Internal Revenue
          Code, corporation, Massachusetts or similar business trust or
          partnership, not formed for the specific purpose of acquiring the
          securities offered, with total assets in excess of $5,000,000; or

      (D) otherwise meets the requirements under Regulation D.

     If the Investor is purchasing the Units hereby in a fiduciary capacity, the
above representations and warranties shall be deemed to have been made on behalf
of the person or persons for whom the Investor is so purchasing.

   3.7    No Public Solicitation.  Neither the offer nor the sale of the Units
          ----------------------
to each Investor has been accomplished by the publication of any form of
advertisement or general solicitation, including, but not limited to, the
following:

      (A) Any advertisement, article, notice or other communication published
          in any newspaper, magazine, or similar media or broadcast over
          television or radio; and

      (B) Any seminar or meeting whose attendees have been invited by any
          general solicitation or general advertising.

   3.8    Restricted Securities.  Each Investor understands that the Units are
          ----------------------
characterized as "restricted securities" under the federal securities laws in as
much as they are being acquired from the Company in a transaction not involving
a public offering and that under such laws and applicable regulations such
securities may be resold without registration under the Securities Act of 1933,
as amended (the "Act"), only in certain limited circumstances.  In this
connection, each Investor represents that such investor is familiar with SEC
Rule 144, as presently in effect, and understands the resale limitations imposed
thereby and by the Act.

   3.9    Further Limitations on Disposition.  Without in any way limiting the
          -----------------------------------
representations set forth above, each Investor further agrees not to make any
disposition of all or any portion of the Units unless and until the transferee
has agreed in writing for the direct benefit of the Company to be bound by this
Section 3, and:

      (A) There is then in effect a Registration Statement under the Act
          covering such proposed disposition and such disposition is made in
          accordance with such Registration Statement; or

      (B) (i)  Such Investor shall have notified the Company of the proposed
               disposition and shall have furnished the Company with a detailed
               statement of the circumstances surrounding the proposed
               disposition, and

-------------------------------------------------------------------------------
Information Analysis Incorporated                                        Page 4
-------------------------------------------------------------------------------
<PAGE>

          (ii) If reasonably requested by the Company, such Investor shall have
               furnished the Company with an opinion of counsel, reasonably
               satisfactory to the Company, that such disposition will not
               require registration of such Units under the Act.  It is agreed
               that the Company will not require opinions of counsel for
               transactions made pursuant to Rule 144, except in unusual
               circumstances.

      (C) Notwithstanding the provisions of paragraphs (A) and (B) above, no
          such registration statement or opinion of counsel shall be necessary
          for a transfer by an Investor which is a partnership to a partner of
          such partnership, or a retired partner of such partnership who retires
          after the date hereof, or to the estate of any such partner or retired
          partner or the transfer by gift, will or intestate succession of any
          partner to his spouse or to the siblings, lineal descendants or
          ancestors of such partner or his spouse, if the transferee agrees in
          writing to be subject to the terms hereof to the same extent as if he
          were an original Investor hereunder.

   3.10   Legends.  It is understood that the certificates evidencing the Units
          --------
may bear one or all of the following legends:

      (A) "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
          OF 1933.  THE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE
          SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A
          REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER
          SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT
          SUCH REGISTRATION IS NOT REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144
          OF SUCH ACT."

      (B) "THIS WARRANT HAS BEEN ACQUIRED FOR INVESTMENT AND HAS NOT BEEN
          REGISTREED UNDER THE SECURITIES ACT OF 1933 OR ANY APPLICABLE STATE
          SECURITIES LAWS.  THIS WARRANT MAY NOT BE OFFERED, PLEDGED, SOLD OR
          TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION
          THEREFROM."

      (C) Any legends required by law.

   3.11   Risks.  Each Investor recognizes that an investment in the Units
          -----
involves significant risks and has taken full cognizance of and understands all
of the risk factors related to the purchase of the Units. The risks associated

described on Exhibit A hereto. Each Investor understands that Exhibit A attached
                                                              ---------

   6.3    Form S-3 Registration.
          ----------------------

      (A) No later than fifteen (15) days after the Initial Closing, the Company
          shall file a registration statement on Form S-3 covering the Common

          Holders;

      (B) The Company shall not be obligated to effect any such registration,
          qualification or compliance, pursuant to this Section 6.3: (1) if Form
          S-3 or another short form registration statement under the Act is not
          available for such registration, except if such short form is not
          available because of a breach by the Company of Section 6.2; (2) if
          the Holders, together with the holders of any other security of the
          Company entitled to inclusion in such registration, propose to sell

          aggregate gross offering price of less than $300,000; (3) if the
          Company shall furnish to such Holders a certificate signed by the
          President of the Company stating that in the good faith judgment of
          the Board of Directors of the Company, it would be seriously
          detrimental to the Company and its shareholders for such Form S-3
          Registration to be effected at such time, in which event the Company
          shall have the right to defer the filing of the Form S-3 registration
          statement for a period of not more than 90 days under this Section
          6.3; provided, however, that the Company shall not utilize this right

          the effective date of any other registration statement relating to an
          underwritten public offering filed by the Company with the SEC so long
          as the Holders have piggyback registration rights under said other
          registration statement; or (5) in any particular jurisdiction in which
          the Company would be required to qualify to do business or to execute
          a general consent to service of process in effecting such
          registration, qualification or compliance.

      (C) All expenses the Company incurs in connection with a registration
          pursuant to this Section 6.3, including (without limitation) all
          registration, filing, qualification, printer's and accounting fees and
          the reasonable fees and disbursements of counsel for the Company shall
          be paid by the Company. All discounts and commissions associated with
          the Registerable Securities shall be borne pro rata by the Holders.

          ---------------

          (a) In the event of a registration of any of the Registerable
Securities under the Securities Act pursuant to this Section 6, the Company will
indemnify and hold harmless each holder of Registerable Securities, its officers
and directors, each underwriter of such Registerable Securities thereunder and
each other person, if any, who controls such seller or underwriter within the
meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, to which such holder, officer, director,
underwriter or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon (i) any untrue statement or
alleged untrue statement of any material fact contained in any registration
statement under which such Registerable Securities was registered under the
Securities Act pursuant to this Section 6, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereof, (ii) any
blue sky application or other document executed by the Company specifically for

any state or other jurisdiction in order to qualify any or all of the
Registerable Securities under the securities laws thereof (any such application,
document or information herein called a "Blue Sky Application"), (iii) the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, (iv)
any violation by the Company or its agents of any rule or regulation promulgated
under the Securities Act applicable to the Company or its agents and relating to
action or inaction required of the Company in connection with such registration,
or (v) any failure to register or qualify the Registerable Securities in any
state where the Company or its agents has affirmatively undertaken or agreed in
writing that the Company (the undertaking of any underwriter chosen by the
Company being attributed to the Company) will undertake such registration or
qualification on the seller's behalf (provided that in such instance the Company
shall not be so liable if it has undertaken its best efforts to so register or
qualify the Registerable Securities) and will reimburse each such holder, and
such officer and director, each such underwriter and each such controlling
person for any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that the Company will not be liable in any such case
        --------  -------
if and to the extent that any such loss, claim, damage or liability arises out
of or is based upon an untrue statement or alleged untrue statement or omission
or alleged omission so made in conformity with information furnished by any such
seller, any such underwriter or any such controlling person in writing
specifically for use in such registration statement or prospectus.

          (b) In the event of a registration of any of the Registerable
Securities under the Securities Act pursuant to this Section 6, each seller of
such Registerable Securities thereunder, severally and not jointly, will
indemnify and hold harmless the Company, each person, if any, who controls the
Company within the meaning of the Securities Act, each officer of the Company
who signs the registration statement, each director of the Company, each other
holder of Registerable Securities, each underwriter and each person who controls
any underwriter within the meaning of the Securities Act, against all losses,
claims, damages or liabilities, joint or several, to which the Company or such
officer, director, other seller, underwriter or controlling person may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in the registration statement under which such Registerable Securities
was registered under the Securities Act pursuant to this Section 6, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereof, or any Blue Sky Application or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse the Company and each such officer, director, other seller,
underwriter and controlling person for any legal or other expenses reasonably
incurred by them in

connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that such seller will be liable
                     --------  -------
hereunder in any such case if and only to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in reliance upon
and in conformity with information pertaining to such seller, as such, furnished
in writing to the Company by such seller specifically for use in such
registration statement or prospectus; and provided, further, however, that the
                                          --------------------------
liability of each seller hereunder shall be limited to the proportion of any
such loss, claim, damage, liability or expense which is equal to the proportion
that the public offering price of the shares sold by such seller under such
registration statement bears to the total public offering price of all
securities sold thereunder, but not in any event to exceed the proceeds received
by such seller from the sale of Registerable Securities covered by such
registration statement.

          (c) Promptly after receipt by an indemnified party hereunder of notice
of the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
such indemnified party other than under this Section 6.4 and shall only relieve
it from any liability which it may have to such indemnified party under this
Section 6.4 if and to the extent the indemnifying party is prejudiced by such
omission. In case any such action shall be brought against any indemnified party
and it shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 6.4 for any legal expenses subsequently incurred by
such indemnified party in connection with the defense thereof other than
reasonable costs of investigation and of liaison with counsel so selected;
provided, however, that, if the defendants in any such action include both the
--------  -------
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that the interests of the indemnified party reasonably
may be deemed to conflict with the interests of the indemnifying party, the
indemnified party shall have the right to select a separate counsel and to
assume such legal defenses and otherwise to participate in the defense of such
action, with the expenses and fees of such separate counsel and other expenses
related to such participation to be reimbursed by the indemnifying party as
incurred.

          (d) The indemnities provided in this Section 6.4 shall survive the
transfer of any Registerable Securities by such holder.

                                   EXHIBIT A
                                  Risk Factors
--------------------------------------------------------------------------------

     Each Investor has carefully considered the risks described below.  If any
of the following risks actually occurs, the Company's business, financial
condition or operating results could be materially adversely affected.  In such
case, the Investors may lose all or part of their investment.

     The risks and uncertainties described below are not the only ones the
Company face.  Additional risks and uncertainties, including those not presently
known to the Company or that the Company currently deem immaterial, may also
impair the Company's business.

RISKS RELATED TO THE COMPANY'S BUSINESS.

The Company's Business Is Difficult to Evaluate Because The Company Has a
Limited Operating History Under The Company's Current Business Model.

     The Company has a limited operating history under the Company's current
business model upon which the Investor can evaluate the Company's business.
Accordingly, an investor in the Company's Securities must consider the
challenges, risks and uncertainties frequently encountered by companies using
new business models in new and rapidly evolving markets.  These challenges
include the Company's:

     *    Need to increase the Company's brand name awareness;
     *    Need to manage changing and expanding operations;
     *    Need to compete effectively;
     *    Dependence on experienced personnel.

     The Company cannot be certain that the Company's business strategy will be
successful or that the Company will successfully address these and other
challenges, risks and uncertainties.  Any failure to do so would seriously harm
the Company's business and operating results.

The Company Has a Negative Current Net Worth; May Incur Future Losses.

     The Company has a negative current net worth and has been incurring losses
on its business operations for the past several years.  The Company is not
currently able to satisfy its obligations and requires additional working
capital.  The Company may continue to incur operating losses.  Operating results
may be affected by factors beyond the Company's control, such as the state of
the economy, business conditions in general and the other factors discussed
herein.

The Company Need to Manage Changing and Expanding Operations.

     The Company expects the Company's business to grow.  This growth may place
a significant strain on the Company's business resources, which have been
reduced as a result of the Company's recent losses.  To manage this growth
effectively, the Company may need to implement additional management information
systems capabilities, further develop the Company's operating, administrative,
financial and accounting systems and controls, improve coordination among
accounting, finance, marketing and operations and hire and train additional
personnel. The Company may not successfully implement the Company's expansion
program in whole or in part.  The Company cannot be certain that the Company's
management will be able to successfully identify, manage and exploit existing
and potential market opportunities.

--------------------------------------------------------------------------------
<PAGE>

The Company's Market is Highly Competitive.

     The Company does business in a market that is highly competitive, and the
Company expects competition to intensify in the future.  Increased competition
is likely to result in price reductions, reduced gross margins and loss of
market share, any of which could harm the Company's net revenue and results of
operations.

     The Company may not be able to compete with current and potential
competitors, many of whom have longer operating histories, greater name
recognition, larger, more established customer bases and significantly greater
financial, technical, and marketing resources. Further, some of the Company's
competitors provide or have the ability to provide the same range of services
the Company offers. Also, competitors may compete directly with the Company by
adopting a similar business model or through the acquisition of companies which
can provide complementary products or services. The Company's failure to compete
effectively in the Company's markets would have a material adverse affect on the
Company's business.

The Company Must Attract and Retain Experienced Personnel and The Company Rely
on Senior Management.

     The success of the Company's business depends to a large extent upon the
efforts of the Company's officers and management personnel.  If the Company
fails to attract, assimilate or retain highly qualified managerial and technical
personnel the Company's business could be materially adversely affected.  The
Company's performance is substantially dependent on the performance of the
Company's executive officers and key employees who must be knowledgeable and
experienced.  The Company is also dependent on its ability to retain and
motivate high quality personnel, especially management and highly skilled
technical teams.  The loss of the services of any executive officers or key
employees could have a material adverse effect on the Company's business.  The
Company's future success also depends on the continuing ability to identify,
hire, train and retain other highly qualified managerial and technical
personnel.  Competition for such personnel is intense.

Discretion as to Use of Proceeds.

     The Company expects that the proceeds from the sale of the Securities will
be used for working capital. The Company expects to also use the proceeds to
meet current operating cost obligations and to make payments on outstanding
obligations which are estimated to be about $1,000,000. However, the projected
uses of proceeds are approximate, and management will have discretion with
respect to the allocation of proceeds.

Proceeds Insufficient to Satisfy Current Obligations.

     The proceeds from the sale of Securities will not be sufficient to satisfy
the full value of the Company's current outstanding obligations. The Company's
creditors are working closely with the Company to allow it to continue
operations while making reduced payments. While the Company does not consider
the risk likely, such creditors can and may sue to collect upon the full amount
of their outstanding obligations at any time.

Revenue May Be Insufficient to Reverse Losses.

     The Company expects its losses to continue; however, cash flow from
operations is likely to be positive. The Company has several large contracts
that are moving toward fruition in the next


--------------------------------------------------------------------------------
Information Analysis Incorporated                                        Page 15
--------------------------------------------------------------------------------
<PAGE>

several months, but if any of these contracts do not become finalized, it could
have a material adverse effect on the Company's operations.

Investment Risk; Additional Financing.

     There can be no assurance that the investors in the Securities will recoup
their investment.  The Company may seek to raise additional capital for future
expansion.  There is no assurance that the Company will be able to raise this
capital.  Should the Company obtain such additional funds, prospective investors
in this Offering may experience dilution of their equity interest in the
Company.

     The Company may not achieve cash flow break-even and may require additional
infusions of capital to sustain operations.  This capital may not be available.
The Company may need to raise additional funds sooner than the Company expects
if the Company incurs unforeseen required capital expenditures or substantial
operating losses.  If adequate funds are not available or are not available on
acceptable terms, the Company may not be able to develop or enhance the
Company's services, take advantage of future opportunities or respond to
competitive pressures, which could have a material adverse effect on the
Company's business.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     The Company's materials may contain statements about future events and
expectations, which are "forward-looking statements."  Any statement in the
Company's materials that is not a statement of historical fact may be deemed to
be a forward-looking statement.  Such forward-looking statements involve known
and unknown risks, uncertainties and other factors which may cause the Company's
actual results, performance or achievements to be materially different from any
future results, performance or achievements expressed or implied by such
forward-looking statements. In evaluating these statements, the Investor should
specifically consider various factors, including the risks outlined in the Risk
Factors section above.  These factors may cause the Company's actual results to
differ materially from any forward-looking statement.  Specific factors that
might cause such a difference include, but are not limited to:

 .  the potential fluctuation in the Company's operating results;
 .  the Company's potential need for additional capital;
 .  the Company's potential inability to expand the Company's services;
 .  the Company's competition; and,
 .  the Company's ability to attract and retain skilled personnel.

     Although the Company believes that the expectations reflected in the
forward-looking statements are reasonable, the Company cannot guarantee future
results, levels of activity, performance or achievements.  Moreover, neither the
Company nor any other person assumes responsibility for the accuracy and
completeness of the forward-looking statements.  The Company is under no duty to
update any of the forward-looking statements to conform such statements to
actual results or to changes in the Company's expectations.

     Use of Financial Forecasts.  Any financial forecasts the Company may have
provided in connection with this Offering are based on assumptions made by the
Company's management in formulating the Company's current business plan.  The
Company can provide no assurance that the assumptions will prove to be valid and
therefore, can give no assurance that the projected yields will be realized.
The validity and accuracy of all such assumptions will depend in large part on
future events over which the Company has limited control.  To the extent that
any of the assumptions upon which the financial forecasts are based are
incorrect or inaccurate, the actual operating results of the Company will not
correspond to the financial forecast.  Such differences

may be material and actual results may differ substantially from those
projected. Accordingly, the Investor should not make an investment in the
Company in reliance on any projected financial performance.
