or after the First Release Date, the holders of a majority in interest of the
Unit Shares, the Warrants and the Warrant Shares collectively, may make a
written demand for registration under the Securities Act of all or part of their
Registrable Securities (a "Demand Registration"). At any time and from time to
time on or after the Second Release Date, the holders of a majority in interest
of the Initial Investor Shares may request a Demand Registration for all or part
of their Registrable Securities. Any demand for a Demand Registration shall
specify the number of shares of Registrable Securities proposed to be sold and
the intended method(s) of distribution thereof. The Company will notify all
holders of Registrable Securities of a requested Demand Registration, and each
holder of Registrable Securities who wishes to include all or a portion of such
holder's Registrable Securities in the Demand Registration (each such holder
including shares of Registrable Securities in such registration, a "Demanding
Holder") shall so notify the Company within fifteen (15) days after the receipt
by the holder of the notice from the Company. Upon any such request, the
Demanding Holders shall be entitled to have their Registrable Securities
included in the Demand Registration, subject to Section 2.1.4 and the provisos
set forth in Section 3.1.1. The Company shall not be obligated to effect more
than an aggregate of on (1) Demand Registration at the request of the holders of
the Unit Shares, the Warrants and the Warrant Shares, collectively two (2)
Demand Registrations at the request of the holders of the Initial Investor
Shares, in each case, under this Section 2.1.1 in respect of Registrable
Securities. Notwithstanding anything to the contrary contained herein, the
Company shall not be required to seek to cause a Registration Statement with
respect to a Demand Registration to become effective pursuant to this Section
2.1: (A) within a period of ninety (90) days after the effective date of a
Registration Statement filed by the Company; provided, that the Company shall
use commercially reasonable efforts to cause a Demand Registration requested
hereunder to be declared effective promptly following such period if such a
request is made during such period; or (B) if the Company shall furnish to the
Demanding Holder or Holders, a certificate signed by the Chief Executive Officer
of the Company stating that in the good faith judgment of the Board of Directors
of the Company, the filing of a Registration Statement would, at such time,
materially and adversely affect (i) the financial condition of the Company, in
view of a requirement to disclose material non-public information relating to
the Company, which the Company has a bona fide business purpose for preserving
as confidential or (ii) an existing continuing negotiation relating to an
acquisition, disposition, corporate reorganization, private securities offering,
financing or similar transaction with respect to the Company, then the Company
shall have the right to defer such filing for a period of no more than ninety
(90) days; provided, however that the Company may not exercise this right more
than once during any period of twelve (12) consecutive months.

                                        4

          2.1.2. Effective Registration. A registration will not count as a
Demand Registration until the Registration Statement filed with the Commission
with respect to such Demand Registration has been declared effective and the
Company has complied with all of its obligations under this Agreement with
respect thereto; provided, however, that if, after such Registration Statement
has been declared effective, the offering of Registrable Securities pursuant to
a Demand Registration is interfered with by any stop order or injunction of the
Commission or any other governmental agency or court, the Registration Statement
with respect to such Demand Registration will be deemed not to have been
declared effective, unless and until, (i) such stop order or injunction is
removed, rescinded or otherwise terminated, and (ii) a majority in interest of
the Demanding Holders thereafter elect to continue the offering.

          2.1.3. Underwritten Offering. If a majority in interest of the
Demanding Holders so elect and such holders so advise the Company as part of
their written demand for a Demand Registration, the offering of such Registrable
Securities pursuant to such Demand Registration shall be in the form of an
underwritten offering. In such event, the Company shall have the right (subject
to the reasonable approval of a majority in interest of the Demanding Holders)
to select the Underwriter(s) for such offering. All Demanding Holders proposing
to distribute their securities through such underwriting shall enter into an
underwriting agreement in customary form with the Underwriter or Underwriters
selected for such underwriting.

          2.1.4. Reduction of Offering. If the managing Underwriter or
Underwriters for a Demand Registration that is to be an underwritten offering
advises the Company and the Demanding Holders in writing that the dollar amount
or number of shares of Registrable Securities which the Demanding Holders desire
to sell, taken together with all other shares of Common Stock or other
securities which the Company desires to sell and the shares of Common Stock or
other securities, if any, as to which registration has been requested pursuant
to written contractual piggy-back registration rights held by other shareholders
of the Company who desire to sell, exceeds the maximum dollar amount or maximum
number of shares that can be sold in such offering without adversely affecting
the proposed offering price, the timing, the distribution method, or the
probability of success of such offering (such maximum dollar amount or maximum
number of shares, as applicable, the "Maximum Number of Shares"), then the
Company shall include in such registration: (i) first, the Registrable
Securities as to which Demand Registration has been requested (all pro rata in
accordance with the number of shares that each such person has requested be
included in such registration, regardless of the number of shares held by each
such person (such proportion is referred to herein as "Pro Rata")) that can be
sold without exceeding the Maximum Number of Shares; (ii) second, to the extent
that the Maximum Number of Shares has not been reached under the foregoing
clause (i), all Purchase Option Securities that can be sold without exceeding
the Maximum Number of Shares; (iii) third, to the extent that the Maximum Number
of Shares has not been reached under the foregoing clauses (i) and (ii), all
shares of Common Stock or other securities that the Company desires to sell and
that can be sold without exceeding the Maximum Number of Shares and (iv) fourth,
to the extent that the Maximum Number of Shares has not been reached under the
foregoing clauses (i),(ii) and (iii),the shares of the account of other persons,
that the Company is obligated to register pursuant to written contractual
arrangements with other persons and that can be sold without exceeding the
Maximum Number of Shares.

                                        5

          2.1.5. Withdrawal. If a majority in interest of the Demanding Holders
disapprove of the terms of any underwriting or are not entitled to include all
of their Registrable Securities in any underwritten offering, such majority in
interest of the Demanding Holders may elect to withdraw from such offering by
giving written notice to the Company and the Underwriter or Underwriters of
their request to withdraw prior to the effectiveness of the Registration
Statement filed with the Commission with respect to such Demand Registration. If
the majority in interest of the Demanding Holders withdraws from a proposed
underwritten offering relating to a Demand Registration, then such registration
shall not count as a Demand Registration provided for in Section 2.1.1.

     2.2 Piggy-Back Registration.

          2.2.1. Piggy-Back Rights. If at any time on or after the First Release
Date the Company proposes to file a Registration Statement under the Securities
Act with respect to an offering of equity securities, or securities or other
obligations exercisable or exchangeable for, or convertible into, equity
securities, by the Company for its own account or for the account of other
securityholders of the Company including, a Registration Statement filed upon
the request of the holders of Purchase Option Securities, other than a
Registration Statement (i) filed in connection with any employee stock option or
other benefit plan, (ii) for an exchange offer or offering of securities solely
to the Company's existing shareholders, (iii) for an offering of debt that is
convertible into equity securities of the Company or (iv) for a dividend
reinvestment plan, then the Company shall (x) give written notice of such
proposed filing to the holders of Registrable Securities as soon as practicable
but in no event less than ten (10) days before the anticipated filing date,
which notice shall describe the amount and type of securities to be included in
such offering, the intended method(s) of distribution, and the name of the
proposed managing Underwriter or Underwriters, if any, of the offering, and (y)
offer to the holders of Registrable Securities in such notice the opportunity to
register the sale of such number of shares of Registrable Securities as such
holders may request in writing within fifteen (15) days following receipt of
such notice (a "Piggy-Back Registration"). The Company shall cause such
Registrable Securities to be included in such registration and shall use its
best efforts to cause the managing Underwriter or Underwriters of a proposed
underwritten offering to permit the Registrable Securities requested to be
included in a Piggy-Back Registration to be included on the same terms and
conditions as any similar securities of the Company and to permit the sale or
other disposition of such Registrable Securities in accordance with the intended
method(s) of distribution thereof. All holders of Registrable Securities
proposing to distribute their securities through a Piggy-Back Registration that
involves an Underwriter or Underwriters shall enter into an underwriting
agreement in customary form with the Underwriter or Underwriters selected for
such Piggy-Back Registration. The Company shall have no obligation under this
Section 2.2 to complete any offering of its securities that it proposes to make.

          2.2.2. Reduction of Offering. If the managing Underwriter or
Underwriters for a Piggy-Back Registration that is to be an underwritten
offering advises the Company and the holders of Registrable Securities in
writing that the dollar amount or number of shares of Common Stock or other
securities which the Company desires to sell, taken together with shares of
Common Stock or other securities, if any, as to which registration has been
demanded pursuant to written contractual arrangements with persons other than
the holders of Registrable Securities hereunder, the Registrable Securities as
to which registration has been requested under

                                        6

this Section 2.2, and the shares of Common Stock or other securities, if any, as
to which registration has been requested pursuant to the written contractual
piggy-back registration rights of other shareholders of the Company, exceeds the
Maximum Number of Shares, then the Company shall include in any such
registration:

               (i) first, the shares of Common Stock or other securities that
the Company or such other requesting holders, as the case may be, desire to
sell;

               (ii) second, to the extent that the Maximum Number of Shares has
not been reached under the foregoing clause (i), the number of Purchase Option
Securities as to which registration has been requested that can be sold without
exceeding the Maximum Number of Shares;

               (iii) third, to the extent that the Maximum Number of Shares has
not been reached under the foregoing clauses (i) and (ii), the number of
Registrable Securities as to which registration as been requested that can be
sold without exceeding the Maximum Number of Shares; and

               (iv) fourth, to the extent that the Maximum Number of Shares has
not been reached under the foregoing clauses (i), (ii) and (iii) the shares of
Common Stock or other securities for the account of the Company or other persons
that the Company is obligated to register pursuant to written contractual
arrangements with such persons, that can be sold without exceeding the Maximum
Number of Shares.

          2.2.3. Withdrawal. Any holder of Registrable Securities may elect to
withdraw such holder's request for inclusion of Registrable Securities in any
Piggy-Back Registration by giving written notice to the Company of such request
to withdraw prior to the effectiveness of the Registration Statement. The
Company may also elect to withdraw a registration statement at any time prior to
the effectiveness of the Registration Statement. Notwithstanding any withdrawal
by the Company, the Company shall pay all expenses incurred by the holders of
Registrable Securities in connection with such Piggy-Back Registration as
provided in Section 3.3.

          2.3 Registrations on Form S-3. In case the Company shall, at any time
after the First Release Date be permitted to effect a registration on Form S-3
or other similar short-form registration which may be available at such time
with respect to all or a part of the Registrable Securities, the holders of
Registrable Securities shall be entitled to request in writing that the Company
register the resale of any or all of such Registrable Securities on Form S-3 or
such other similar short-form registration; provided, however, that the Company
shall not be obligated to effect such request through an underwritten offering.
Upon receipt of such written request, the Company will promptly give written
notice of the proposed registration to all other holders of Registrable
Securities, and, as soon as practicable thereafter, effect the registration of
all or such portion of such holder's or holders' Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities of any other holder or holders joining in such request as are
specified in a written request given within fifteen (15) days after receipt of
such written notice from the Company; provided, however, that the Company shall
not be obligated to effect any such registration pursuant to this Section 2.3 if
the holders of the

                                        7

Registrable Securities, together with the holders of any other securities of the
Company entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) at any aggregate price to the
public of less than $500,000. Registrations effected pursuant to this Section
2.3 shall not be counted as Demand Registrations effected pursuant to Section
2.1. Notwithstanding anything to the contrary contained herein, the Company
shall not be required to seek to cause a Registration Statement with respect to
a Form S-3 or other short-form registration to become effective pursuant to this
Section 2.3: (A) within a period of ninety (90) days after the effective date of
a Registration Statement filed by the Company; provided, that the Company shall
use commercially reasonable efforts to cause a Form S-3 or other short-form
registration requested hereunder to be declared effective promptly following
such period if such a request is made during such period; or (B) if the Company
shall furnish to the requesting holder or holders, a certificate signed by the
Chief Executive Officer of the Company stating that in the good faith judgment
of the Board of Directors of the Company, the filing of a Registration Statement
would, at such time, materially and adversely affect (i) the financial condition
of the Company, in view of a requirement to disclose material non-public
information relating to the Company, which the Company has a bona fide business
purpose for preserving as confidential or (ii) an existing continuing
negotiation relating to an acquisition, disposition, corporate reorganization,
private securities offering, financing or similar transaction with respect to
the Company, then the Company shall have the right to defer such filing for a
period of no more than ninety (90) days; provided, however that the Company may
not exercise this right more than once during any period of twelve (12)
consecutive months.

the holders of Registrable Securities included in such Registration Statement to
consummate the disposition of such Registrable Securities in such jurisdictions;

to expedite or facilitate the disposition of Registrable Securities. The
representations, warranties and covenants of the Company in any underwriting
agreement which are made to or for the benefit of any Underwriters, to the
extent applicable, shall also be made to and for the benefit of the holders of
the Registrable Securities included in such underwritten public offering. No

holder of Registrable Securities included in any Registration Statement a signed
counterpart, addressed to such holder, of (i) any opinion of counsel to the
Company delivered to any Underwriter and (ii) any comfort letter from the
Company's independent public accountants delivered to any Underwriter. In the
event no legal opinion is delivered to any Underwriter, the Company shall
furnish to each holder of Registrable Securities included in such Registration
Statement, at any time that such holder elects to use a prospectus, an opinion
of counsel to the Company to the effect that the Registration Statement
containing such prospectus has been declared effective and that no stop order is
in effect.

          3.1.10. Earnings Statement. The Company shall comply with all
applicable rules and regulations of the Commission and the Securities Act, and
make available to its shareholders, as soon as practicable, an earnings
statement covering a period of twelve (12) months, beginning within three (3)
months after the effective date of the registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder.

          3.1.11. Listing. The Company shall use its best efforts to cause all
Registrable Securities included in any registration to be listed on such
exchanges or otherwise designated for trading in the same manner as similar
securities issued by the Company are then listed or designated.

     3.2 Obligation to Suspend Distribution. Upon receipt of any notice from the
Company of the happening of any event of the kind described in Section
3.1.4(iv), or, in the case of a resale registration on Form S-3 or similar
short-form registration effected pursuant to Section 2.3 hereof, upon any
suspension by the Company, pursuant to a written insider trading compliance
program adopted by the Company's Board of Directors, of the ability of all
"insiders" covered by such program to transact in the Company's securities
because of the existence of material non-public information, each holder of
Registrable Securities included in any registration shall immediately
discontinue disposition of such Registrable Securities pursuant to the
Registration Statement covering such Registrable Securities until such holder
receives the supplemented or amended prospectus contemplated by Section
3.1.4(iv) or the restriction on the ability of "insiders" to transact in the
Company's securities is removed, as applicable, and, if so directed by the
Company, each such holder will deliver to the Company all copies, other than
permanent file copies then in such holder's possession, of the most recent
prospectus covering such Registrable Securities at the time of receipt of such
notice.

     3.3 Registration Expenses. The Company shall bear all costs and expenses
incurred in connection with any Demand Registration pursuant to Section 2.1, any
Piggy-Back Registration pursuant to Section 2.2, and any registration on Form
S-3 effected pursuant to Section 2.3, and all expenses incurred in performing or
complying with its other obligations under this Agreement, whether or not the
Registration Statement becomes effective, including, without limitation: (i) all
registration and filing fees; (ii) fees and expenses of compliance with
securities or "blue sky" laws (including fees and disbursements of counsel in
connection with blue sky qualifications of the Registrable Securities); (iii)
printing expenses; (iv) the Company's internal expenses (including, without
limitation, all salaries and expenses of its officers and employees); (v) the
fees and expenses incurred in connection with the listing of the Registrable

                                       11

Securities as required by Section 3.1.11; (vi) National Association of
Securities Dealers, Inc. fees; (vii) fees and disbursements of counsel for the
Company and fees and expenses for independent certified public accountants
retained by the Company (including the expenses or costs associated with the
delivery of any opinions or comfort letters requested pursuant to Section
3.1.9); (viii) the fees and expenses of any special experts retained by the
Company in connection with such registration and (ix) the fees and expenses of
one legal counsel selected by the holders of a majority in interest of the
Registrable Securities included in such registration. The Company shall have no
obligation to pay any underwriting discounts or selling commissions attributable
to the Registrable Securities being sold by the holders thereof, which
underwriting discounts or selling commissions shall be borne by such holders.
Additionally, in an underwritten offering, all selling shareholders and the
Company shall bear the expenses of the underwriter pro rata in proportion to the
respective amount of shares each is selling in such offering.

     3.4 Information. The holders of Registrable Securities shall provide such
information as may reasonably be requested by the Company, or the managing
Underwriter, if any, in connection with the preparation of any Registration
Statement, including amendments and supplements thereto, in order to effect the
registration of any Registrable Securities under the Securities Act pursuant to
Section 2 and in connection with the Company's obligation to comply with federal
and applicable state securities laws.

     4. INDEMNIFICATION AND CONTRIBUTION.

     4.1 Indemnification by the Company. The Company agrees to indemnify and
hold harmless each Investor and each other holder of Registrable Securities, and
each of their respective officers, employees, affiliates, directors, partners,
members, attorneys and agents, and each person, if any, who controls an Investor
and each other holder of Registrable Securities (within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act) (each, an "Investor
Indemnified Party"), from and against any expenses, losses, judgments, claims,
damages or liabilities, whether joint or several, arising out of or based upon
any untrue statement (or allegedly untrue statement) of a material fact
contained in any Registration Statement under which the sale of such Registrable
Securities was registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained in the Registration Statement,
or any amendment or supplement to such Registration Statement, or arising out of
or based upon any omission (or alleged omission) to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by the Company of the Securities Act or any rule or
regulation promulgated thereunder applicable to the Company and relating to
action or inaction required of the Company in connection with any such
registration; and the Company shall promptly reimburse the Investor Indemnified
Party for any legal and any other expenses reasonably incurred by such Investor
Indemnified Party in connection with investigating and defending any such
expense, loss, judgment, claim, damage, liability or action; provided, however,
that the Company will not be liable in any such case to the extent that any such
expense, loss, claim, damage or liability arises out of or is based upon any
untrue statement or allegedly untrue statement or omission or alleged omission
made in such Registration Statement, preliminary prospectus, final prospectus,
or summary prospectus, or any such amendment or supplement, in reliance upon and
in conformity with information furnished to the Company, in writing, by such
selling holder expressly for use

                                       12

therein. The Company also shall indemnify any Underwriter of the Registrable
Securities, their officers, employees, affiliates, directors, partners, members
and agents and each person who controls such Underwriter on substantially the
same basis as that of the indemnification provided above in this Section 4.1.

     4.2 Indemnification by Holders of Registrable Securities. Each selling
holder of Registrable Securities will, in the event that any registration is
being effected under the Securities Act pursuant to this Agreement of any
Registrable Securities held by such selling holder, indemnify and hold harmless
the Company, each of its directors and officers and each Underwriter (if any),
and each other person, if any, who controls such selling holder or such
Underwriter or the Company within the meaning of the Securities Act or the
Exchange Act, against any losses, claims, judgments, damages or liabilities,
whether joint or several, insofar as such losses, claims, judgments, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or allegedly untrue statement of a material fact contained in
any Registration Statement under which the sale of such Registrable Securities
was registered under the Securities Act, any preliminary prospectus, final
prospectus or summary prospectus contained in the Registration Statement, or any
amendment or supplement to the Registration Statement, or arise out of or are
based upon any omission or the alleged omission to state a material fact
required to be stated therein or necessary to make the statement therein not
misleading, if the statement or omission was made in reliance upon and in
conformity with information furnished in writing to the Company by such selling
holder expressly for use therein, and shall reimburse the Company, its directors
and officers, and each such controlling person for any legal or other expenses
reasonably incurred by any of them in connection with investigation or defending
any such loss, claim, damage, liability or action. Each selling holder's
indemnification obligations hereunder shall be several and not joint and shall
be limited to the amount of any net proceeds actually received by such selling
holder from the sale of Registrable Securities which gave rise to such
indemnification obligation.

     4.3 Conduct of Indemnification Proceedings. Promptly after receipt by any
person of any notice of any loss, claim, damage or liability or any action in
respect of which indemnity may be sought pursuant to Section 4.1 or 4.2, such
person (the "Indemnified Party") shall, if a claim in respect thereof is to be
made against any other person for indemnification hereunder, notify such other
person (the "Indemnifying Party") in writing of the loss, claim, judgment,
damage, liability or action; provided, however, that the failure by the
Indemnified Party to notify the Indemnifying Party shall not relieve the
Indemnifying Party from any liability which the Indemnifying Party may have to
such Indemnified Party hereunder, except and solely to the extent the
Indemnifying Party is actually prejudiced by such failure. If the Indemnified
Party is seeking indemnification with respect to any claim or action brought
against the Indemnified Party, then the Indemnifying Party shall be entitled to
participate in such claim or action, and, to the extent that it wishes, jointly
with all other Indemnifying Parties, to assume control of the defense thereof
with counsel satisfactory to the Indemnified Party. After notice from the
Indemnifying Party to the Indemnified Party of its election to assume control of
the defense of such claim or action, the Indemnifying Party shall not be liable
to the Indemnified Party for any legal or other expenses subsequently incurred
by the Indemnified Party in connection with the defense thereof other than
reasonable costs of investigation; provided, however, that in any action in
which both the Indemnified Party and the Indemnifying Party are named as
defendants, the Indemnified Party shall have the right to employ separate
counsel (but no more than one such

                                       13

separate counsel) to represent the Indemnified Party and its controlling persons
who may be subject to liability arising out of any claim in respect of which
indemnity may be sought by the Indemnified Party against the Indemnifying Party,
with the fees and expenses of such counsel to be paid by such Indemnifying Party
if, based upon the written opinion of counsel of such Indemnified Party,
representation of both parties by the same counsel would be inappropriate due to
actual or potential differing interests between them. No Indemnifying Party
shall, without the prior written consent of the Indemnified Party, consent to
entry of judgment or effect any settlement of any claim or pending or threatened
proceeding in respect of which the Indemnified Party is or could have been a
party and indemnity could have been sought hereunder by such Indemnified Party,
unless such judgment or settlement includes an unconditional release of such
Indemnified Party from all liability arising out of such claim or proceeding.

     4.4 Contribution.

          4.4.1. If the indemnification provided for in the foregoing Sections
4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of any loss,
claim, damage, liability or action referred to herein, then each such
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 loss, claim, damage, liability or action in such proportion as is
appropriate to reflect the relative fault of the Indemnified Parties and the
Indemnifying Parties in connection with the actions or omissions which resulted
in such loss, claim, damage, liability or action, as well as any other relevant
equitable considerations. The relative fault of any Indemnified Party and any
Indemnifying Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by such Indemnified Party or such Indemnifying Party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

          4.4.2. The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 4.4 were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding Section
4.4.1. The amount paid or payable by an Indemnified Party as a result of any
loss, claim, damage, liability or action referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses incurred by such Indemnified Party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 4.4, no holder of Registrable
Securities shall be required to contribute any amount in excess of the dollar
amount of the net proceeds (after payment of any underwriting fees, discounts,
commissions or taxes) actually received by such holder from the sale of
Registrable Securities which gave rise to such contribution obligation. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     5. UNDERWRITING AND DISTRIBUTION.

     5.1 Rule 144. The Company covenants that it shall file any reports required
to be filed by it under the Securities Act and the Exchange Act and shall take
such further action as the

                                       14

holders of Registrable Securities may reasonably request, all to the extent
required from time to time to enable such holders to sell Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 under the Securities Act, as such Rules may be
amended from time to time, or any similar Rule or regulation hereafter adopted
by the Commission.

out of or relating in any way to this Agreement shall be brought and enforced in
the courts of the State of New York or the United States District Court for the
Southern District of New York (each, a "New York Court"), and irrevocably
submits to such jurisdiction, which jurisdiction shall be exclusive. Each of the
parties hereby waives any objection to such exclusive jurisdiction and that such
courts represent an inconvenient forum. [Each of ________________ and

                            PLACEMENT UNIT AGREEMENT

     PLACEMENT UNIT AGREEMENT (this "Agreement") made as of this ___ day of
_____, 2006 among Vector Intersect Security Acquisition Corp, a Delaware
corporation (the "Company") and the undersigned (the "Purchasers").

     WHEREAS, the Company has filed with the Securities and Exchange Commission
("SEC") a registration statement on Form S-1, as amended (File No. 333-127644)
(the "Registration Statement"), in connection with the Company's initial public
offering (the "IPO") of up to 8,517,188 units, each unit ("Unit") consisting of
one share of the Company's common stock, $.001 par value (the "Common Stock"),
and (ii) one warrant (the "Warrants"), each Warrant to purchase one share of
Common Stock; and

     WHEREAS, the Company desires to sell in a private placement to the
Purchasers (the "Placement") an aggregate of 93,750 units (the "Placement
Units") substantially identical to the Units being issued in the IPO pursuant to
the terms and conditions hereof and as set forth in the Registration Statement,
except that the Placement Units, Common Stock and Warrants to be issued in the
Placement shall not be registered under the Securities Act of 1933, as amended
(the "Securities Act");

     WHEREAS, each Purchaser desires to acquire the number of Placement Units
set forth opposite his name on Schedule A hereto;

     WHEREAS, the Warrants included in the Placement Units shall be governed by
the Warrant Agreement filed as an exhibit to the Registration Statement; and

     WHEREAS, the Purchasers are entitled to registration rights with respect to
the Common Stock and the Warrants comprising the Placement Units and the Common
Stock underlying such Warrants (collectively, the "Registrable Securities") on
the terms set forth in the Registration Rights Agreement filed as an exhibit to
the Registration Statement.

     NOW, THEREFORE, for and in consideration of the premises and the mutual
covenants hereinafter set forth, the parties hereto do hereby agree as follows:

     1. Purchase of Units. The Purchasers hereby agree, directly or through
nominees, to purchase an aggregate of 93,750 Placement Units at a purchase price
of $8.00 per Placement Unit, or an aggregate of $750,000 (the "Purchase Price").
Such purchases shall be in the names and amounts set forth on Schedule A hereto.

     2. Closing. The closing of the purchase and sale of the Placement Units
(the "Closing") will take place at such time and place as the parties may agree
(the "Closing Date"), but in no event later than the date on which the SEC
declares the Registration Statement effective (the "Effective Date"). On the
Effective Date, the Purchasers shall pay the Purchase Price by wire transfer of
funds to an account maintained by the Company. Immediately prior to the closing
of the IPO, the Company shall deposit the Purchase Price into the trust account
described in the Registration Statement (the "Trust Account"). The certificates
for the Common Stock and Warrants comprising the Placement Units shall be
delivered to the Purchasers promptly after the closing of the IPO.

     3. Voting of Shares; Waiver of Appraisal Rights. If the Company solicits
approval of its stockholders of a Business Combination, the Purchasers shall
vote all of the shares of the Common Stock acquired by the Purchasers (i)
pursuant to this Agreement, (ii) in the IPO and (iii) in the aftermarket in
favor of the Business Combination and therefore waive any redemption rights and
any appraisal rights under Section 262 of the Delaware General Corporation Law
they might have with respect to any or all of such shares. As used herein, a
"Business Combination" shall mean a merger, capital stock exchange, asset or
stock acquisition of, or other similar business combination with, one or more
Target Businesses (as hereinafter defined) having a fair market value of at
least 80% of the Company's net assets at the time of such acquisition. As used
herein, the term "Target Business" shall mean a business engaged in the United
States homeland security, national security and/or command and control
industries or a business relating to the manufacture of products for use in such
industries.

     4. Waiver of Liquidation Distributions. In connection with the Placement
Units purchased pursuant to this Agreement, the Purchasers hereby waive any and
all right, title, interest or claim of any kind in or to any liquidating
distributions by the Company in the event of a liquidation of the Company upon
the Company's failure to timely complete a Business Combination. For purposes of
clarity, any shares of Common Stock purchased in the IPO or the aftermarket by
the Purchasers shall be eligible to receive any liquidating distributions by the
Company.

     5. Representations and Warranties of the Purchasers. Each Purchaser hereby
represents and warrants on behalf of itself to the Company that:

          5.1 Such Purchaser is an "accredited investor" as that term is defined
in Rule 501 of Regulation D promulgated under the Securities Act.

          5.2 The Placement Units, Common Stock and Warrants are being acquired
