shall prepare and file with the Commission a "Shelf" Registration Statement
covering the resale of the Registrable Securities on the Filing Date for an
offering to be made on a continuous basis pursuant to Rule 415. The Registration
Statement shall be on Form S-2 (unless the Company is not then eligible to
register for resale the Registrable Securities on Form S-2, in which case such
registration shall be on another appropriate form in accordance herewith) and
shall contain (unless otherwise directed by the Holders) substantially the "Plan
of Distribution" attached hereto as Annex A. Subject to the terms of this
Agreement, the Company shall use commercially reasonable efforts to cause the
Registration Statement to be declared effective under the Securities Act by the
Effectiveness Date and shall use its commercially reasonable efforts to keep
such Registration Statement continuously effective under the Securities Act
until the earlier of (a) the date on which the Genex Stockholder no longer owns
any of the Registrable Securities and (b) until all Registrable Securities
covered by such Registration Statement have been sold or may be sold without
volume restrictions pursuant to Rule 144 as determined by the counsel to the
Company pursuant to a written opinion letter to such effect, addressed and
acceptable to the Company's transfer agent and the affected Holders (the
"Effectiveness Period"). The Company shall promptly notify the Holders via email
of the effectiveness of the Registration Statement.

                  (b) After the date on which the Registration Statement is
declared effective by the SEC, the Company may delay the disclosure of material
non-public information concerning the Company by suspending the use of the
prospectus included in the Registration Statement for a period of time not to
exceed thirty (30) consecutive Trading Days (each, a "Blackout Period") if the
Board of Directors of the Company shall have determined in good faith that it is
in the best interest of the Company to suspend such use; provided that the
Company shall promptly (i) notify the Holders in writing of the existence of
(but in no vent, without the prior written consent of the Holders, shall the
Company disclose to such Holders any facts or circumstances regarding) material
non-public information giving rise to a Blackout Period, (ii) advise the Holders
in writing to cease all sales under the Registration Statement until the end of
the Blackout Period and (iii) use commercially reasonable efforts to terminate
the blackout Period as promptly as possible. The Company may not declare more
than two Blackout Periods in any 365-calendar day period.

         3. Registration Procedures.

         In connection with the Company's registration obligations hereunder,
the Company shall:

                                       3
<PAGE>

         (a) Not less than two Trading Days prior to the filing of each
Registration Statement or any related Prospectus or any amendment or supplement
thereto (including any document that would be incorporated or deemed to be
incorporated therein by reference), the Company shall permit a single firm of
counsel designated by the Genex Stockholder (which until further notice shall be
deemed to be [_________]) to review the Registration Statement and all
amendments and supplements thereto prior to their filing with the Commission.

         (b) (i) Prepare and file with the Commission such amendments, including
post-effective amendments, to the Registration Statement and the Prospectus used
in connection therewith as may be necessary to keep a Registration Statement
continuously effective as to the Registrable Securities for the Effectiveness
Period; (ii) cause the related Prospectus to be amended or supplemented by any
required Prospectus supplement (subject to the terms of this Agreement), and as
so supplemented or amended to be filed pursuant to Rule 424; (iii) respond
promptly to any comments received from the Commission with respect to the
Registration Statement or any amendment thereto and promptly provide the Holders
true and complete copies of all correspondence from and to the Commission
relating to the Registration Statement; and (iv) comply in all material respects
with the provisions of the Securities Act and the Exchange Act with respect to
the disposition of all Registrable Securities covered by the Registration
Statement during the applicable period in accordance (subject to the terms of
this Agreement) with the intended methods of disposition by the Holders thereof
set forth in the Registration Statement as so amended or in the Prospectus as so
supplemented.

         (c) Notify the Holders of Registrable Securities to be sold (which
notice shall, pursuant to clauses (ii) through (v) hereof, be accompanied by an
instruction to suspend the use of the Prospectus until the requisite changes
have been made) promptly (and, in the case of (i)(A) below, not less than two
Trading Days prior to such filing) (i)(A) when a Prospectus or any Prospectus
supplement or post-effective amendment to the Registration Statement is proposed
to be filed; (B) when the Commission notifies the Company whether there will be
a "review" of the Registration Statement and whenever the Commission comments in
writing on the Registration Statement (the Company shall provide true and
complete copies thereof and all written responses thereto to each of the
Holders); and (C) with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of a Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) of the receipt by the Company of any notification with respect to
the suspension of the qualification or exemption from qualification of any of
the Registrable Securities for sale in any jurisdiction, or the initiation or
threatening of any Proceeding for such purpose; and (v) of the occurrence of any
event or passage of time that makes the financial statements included in the
Registration Statement ineligible for inclusion therein or any statement made in
the Registration Statement or Prospectus or any document incorporated or deemed
to be incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

                                       4
<PAGE>

         (d) Promptly deliver to each Holder, without charge, as many copies of
the Prospectus or Prospectuses (including each form of prospectus) and each
amendment or supplement thereto as such Holder may reasonably request. Subject
to the terms of this Agreement, the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

         (e) Use commercially reasonable efforts to register or qualify the
resale of such Registrable Securities as required under applicable securities or
Blue Sky laws of each State within the United States as any Holder requests in
writing, to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period; provided that the Company
shall not be required to qualify generally to do business in any jurisdiction
where it is not then so qualified or subject the Company to any material tax in
any such jurisdiction where it is not then so subject.

         (f) Cooperate with the Holders to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be delivered to
a transferee pursuant to a Registration Statement, which certificates shall be
free, to the extent permitted by the Merger Agreement, of all restrictive
legends, and to enable such Registrable Securities to be in such denominations
and registered in such names as any such Holders may request.

         (g) Upon the occurrence of any event contemplated by this Section 3, as
promptly as reasonably possible, prepare a supplement or amendment, including a
post-effective amendment, to a Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither a Registration Statement nor such Prospectus will
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. If the
Company notifies the Holders in accordance with clauses (ii) through (v) of
Section 3(c) above to suspend the use of the Prospectus until the requisite
changes to such Prospectus have been made, or the Company otherwise notifies the
Holders of its election to suspend the availability of the Registration
Statement and Prospectus pursuant to [Section 2(b)], then the Holders shall
suspend use of such Prospectus. The Company will use its best efforts to ensure
that the use of the Prospectus may be resumed as promptly as is practicable.

         (h) Comply with all applicable rules and regulations of the Commission.

                                       5
<PAGE>

         (i) Use its commercially reasonable efforts to avoid the issuance of,
or, if issued, obtain the withdrawal of (i) any order suspending the
effectiveness of a Registration Statement, or (ii) any suspension of the
qualification (or exemption from qualification) of any of the Registrable
Securities for sale in any jurisdiction in which the Company shall be requested
to keep such registration or qualification effective pursuant to Section 3(e)
herein.

         (j) The Company may require, at any time prior to the second Trading
Day prior to the Filing Date, each Holder to furnish to the Company a statement
as to the number of shares of Common Stock beneficially owned by such Holder
and, if requested by the Commission, the controlling person thereof, within two
Trading days of the Company's request.

         4. Registration Expenses. All fees and expenses incident to the
performance of or compliance with this Agreement by the Company shall be borne
by the Company whether or not any Registrable Securities are sold pursuant to
the Registration Statement. The fees and expenses referred to in the foregoing
sentence shall include, without limitation, (i) all registration and filing fees
(including, without limitation, fees and expenses (A) with respect to filings
required to be made with the principal market on which the Common Stock is then
listed for trading, and (B) in compliance with applicable state securities or
Blue Sky laws reasonably agreed to by the Company in writing (including, without
limitation, fees and disbursements of counsel for the Company in connection with
Blue Sky qualifications or exemptions of the Registrable Securities and
determination of the eligibility of the Registrable Securities for investment
under the laws of such jurisdictions as requested by the Holders )), (ii)
printing expenses (including, without limitation, expenses of printing
certificates for Registrable Securities and of printing prospectuses requested
by the Holders), (iii) messenger, telephone and delivery expenses, (iv) fees and
disbursements of counsel for the Company, and (v) fees and expenses of all other
Persons retained by the Company in connection with the consummation of the
transactions contemplated by this Agreement. In addition, the Company shall be
responsible for all of its internal expenses incurred in connection with the
consummation of the transactions contemplated by this Agreement (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit and the
fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange as required hereunder. In no event shall
the Company be responsible for any broker or similar commissions or any legal
fees or other costs of the Holders.

         5. Indemnification.

         (a) INDEMNIFICATION BY THE COMPANY. The Company shall, notwithstanding
any termination of this Agreement, indemnify and hold harmless each Holder, the
officers, directors, and employees of each of them, each Person who controls any
such Holder (within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act) and the officers, directors, and employees of each such
controlling Person, to the fullest extent permitted by applicable law, from and
against any and all losses, claims, damages, liabilities, costs (including,
without limitation, costs of preparation and reasonable attorneys' fees) and


                                       6
<PAGE>

expenses (collectively, "Losses"), as incurred, arising out of or relating to
any untrue or alleged untrue statement of a material fact contained in a
Registration Statement, any Prospectus or any form of prospectus or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out
of or relating to any omission or alleged omission of a material fact required
to be stated therein or necessary to make the statements therein (in the case of
any Prospectus or form of prospectus or supplement thereto, in light of the
circumstances under which they were made) not misleading, except to the extent,
but only to the extent, that (1) such untrue statements or omissions or alleged
untrue statements or omissions are based upon information regarding such Holder
furnished in writing to the Company by such Holder expressly for use therein, or
to the extent that such information relates to such Holder or such Holder's
proposed method of distribution of Registrable Securities and was reviewed and
expressly approved in writing by such Holder expressly for use in a Registration
Statement, such Prospectus or such form of Prospectus or in any amendment or
supplement thereto or (2) in the case of an occurrence of an event of the type
specified in Section 2(b) or Section 3(c)(ii)-(v), the use by such Holder of an
outdated or defective Prospectus after the Company has notified such Holder in
writing that the Prospectus is outdated or defective and prior to the receipt by
such Holder of the Advice contemplated in Section 6(d). The Company shall notify
the Holders promptly of the institution, threat or assertion of any Proceeding
arising from or in connection with the transactions contemplated by this
Agreement of which the Company is aware.

         (b) INDEMNIFICATION BY HOLDERS. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, its directors, officers, and
employees, each Person who controls the Company (within the meaning of Section
15 of the Securities Act and Section 20 of the Exchange Act), and the directors,
officers, or employees of such controlling Persons, to the fullest extent
permitted by applicable law, from and against all Losses (as determined by a
court of competent jurisdiction in a final judgment not subject to appeal or
review) arising out of or based upon any untrue statement of a material fact
contained in any Registration Statement, any Prospectus, or any form of
prospectus, or in any amendment or supplement thereto, or arising solely out of
or based solely upon: (i) such Holder's failure to comply with the prospectus
delivery requirements of the Securities Act or (ii) any omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading to the extent, but only to the extent, such untrue statement or
omission is contained in any information so furnished in writing by such Holder
to the Company specifically for inclusion in such Registration Statement or such
Prospectus or to the extent that (1) such untrue statements or omissions are
based upon information regarding such Holder furnished in writing to the Company
by such Holder expressly for use therein, or to the extent such information
relates to such Holder or such Holder's proposed method of distribution of
Registrable Securities and was reviewed and expressly approved in writing by
such Holder expressly for use in the Registration Statement, such Prospectus or
such form of Prospectus or in any amendment or supplement thereto or (2) in the
case of an occurrence of an event of the type specified in Section 2(b) or
Section 3(c)(ii)-(v), the use by such Holder of an outdated or defective
Prospectus after the Company has notified such Holder in writing that the
Prospectus is outdated or defective and prior to the receipt by such Holder of
the Advice contemplated in Section 6(d). In no event shall the liability of any
selling Holder hereunder be greater in amount than the dollar amount of the net
proceeds received by such Holder upon the sale of the Registrable Securities
giving rise to such indemnification obligation.

                                       7
<PAGE>

         (c) CONDUCT OF INDEMNIFICATION PROCEEDINGS. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party shall promptly notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the payment of all
fees and expenses incurred in connection with defense thereof; provided, that
the failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that such failure shall have prejudiced the
Indemnifying Party.

         An Indemnified Party shall have the right to employ separate counsel in
any such Proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or
Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a material conflict of interest is
likely to exist if the same counsel were to represent such Indemnified Party and
the Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and the expense of one such counsel for all
Holders shall be at the expense of the Indemnifying Party). The Indemnifying
Party shall not be liable for any settlement of any such Proceeding effected
without its written consent, which consent shall not be unreasonably withheld.
No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending Proceeding in respect of
which any Indemnified Party is a party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability on claims
that are the subject matter of such Proceeding.

         Subject to the terms of this Agreement, all fees and expenses of the
Indemnified Party (including reasonable fees and expenses to the extent incurred
in connection with investigating or preparing to defend such Proceeding in a
manner not inconsistent with this Section) shall be paid to the Indemnified
Party, as incurred, within thirty days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided, that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder).

                                       8
<PAGE>

         (d) CONTRIBUTION. If a claim for indemnification under Section 5(a) or
5(b) is unavailable to an Indemnified Party (by reason of public policy or
otherwise), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action, statement or omission. The amount paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys' or other
reasonable fees or expenses incurred by such party in connection with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the indemnification provided for in this Section was available to
such party in accordance with its terms.

         The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.

         The indemnity and contribution agreements contained in this Section are
in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

         6. Miscellaneous.

         (a) AMENDMENTS AND WAIVERS. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given, unless the same shall be in writing and signed by the Company and the
Holders of a majority of the then outstanding Registrable Securities.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of one or
some Holders and that does not directly or indirectly affect the rights of other
Holders may be given by Holders of all of the Registrable Securities to which
such waiver or consent relates; provided, however, that the provisions of this
sentence may not be amended, modified, or supplemented except in accordance with
the provisions of the immediately preceding sentence.

                                       9

         (b) NO INCONSISTENT AGREEMENTS. Neither the Company nor any of its
subsidiaries has entered, as of the date hereof, nor shall the Company or any of
its subsidiaries, on or after the date of this Agreement, enter into any
agreement with respect to its securities, that conflicts with the provisions
hereof, except for such agreements, the conflicting provisions of which have
been waived.

         (c) COMPLIANCE. Each Holder covenants and agrees that it will comply
with the prospectus delivery requirements of the Securities Act as applicable to
it in connection with sales of Registrable Securities pursuant to the

         (d) DISCONTINUED DISPOSITION. Each Holder agrees by its acquisition of
such Registrable Securities that, upon receipt of a notice from the Company of
the occurrence of any event of the kind described in Section 2(b) or Sections
3(c)(ii) or (iii), such Holder will forthwith discontinue disposition of such
Registrable Securities under a Registration Statement until such Holder's
receipt of the copies of the supplemented Prospectus and/or amended Registration
Statement contemplated by Section 3(h), or until it is advised in writing (the

                                     ANNEX A
                                     -------

                              Plan of Distribution
                              --------------------

         Each Selling Stockholder (the "Selling Stockholders") of the common
stock ("Common Stock") of Markland Technologies, Inc., a Florida corporation
(the "Company") and any of their pledgees, assignees and successors-in-interest
may, from time to time, sell any or all of their shares of Common Stock on the
Over the Counter Bulletin Board or any other stock exchange, market or trading
facility on which the shares are traded or in private transactions. These sales
may be at fixed or negotiated prices. A Selling Stockholder may use any one or
more of the following methods when selling shares:

         o        ordinary brokerage transactions and transactions in which the
                  broker-dealer solicits the Selling Stockholder;

         o        block trades in which the broker-dealer will attempt to sell
                  the shares as agent but may position and resell a portion of
                  the block as principal to facilitate the transaction;

         o        purchases by a broker-dealer as principal and resale by the
                  broker-dealer for its account;

         o        an exchange distribution in accordance with the rules of the
                  applicable exchange;

         o        privately negotiated transactions;

         o        broker-dealers may agree with the Selling Stockholders to sell
                  a specified number of such shares at a stipulated price per
                  share;

         o        a combination of any such methods of sale; or

         o        any other method permitted pursuant to applicable law.

         The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act"), if available, rather
than under this prospectus. Broker-dealers engaged by the Selling Stockholders
may arrange for other brokers-dealers to participate in sales. Broker-dealers
may receive commissions or discounts from the Selling Stockholders (or, if any
broker-dealer acts as agent for the purchaser of shares, from the purchaser) in
amounts to be negotiated. Each Selling Stockholder does not expect these
commissions and discounts relating to its sales of shares to exceed what is
customary in the types of transactions involved.

         The Selling Stockholders may from time to time pledge or grant a
security interest in some or all of the Shares owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell the shares of Common Stock from time to time under
this prospectus, or under an amendment to this prospectus under Rule 424(b)(3)
or other applicable provision of the Securities Act amending the list of Selling
Stockholders to include the pledgee, transferee or other successor in interest
as Selling Stockholders under this prospectus.

                                       13

         The Selling Stockholders also may transfer the shares of Common Stock
in other circumstances, in which case the transferees, pledgees or other
successors in interest will be the selling beneficial owners for purposes of
this prospectus.

         The Company is required to pay certain fees and expenses incurred by
the Company incident to the registration of the shares. The Company has agreed
to indemnify the Selling Stockholders against certain losses, claims, damages
and liabilities, including liabilities under the Securities Act.
