         This Securities Purchase Agreement (this "AGREEMENT") is made and
entered into as of December 21, 2004 (the "EXECUTION DATE"), by and among GVI
Security Solutions, Inc. (formerly Thinking Tools, Inc.), a Delaware corporation
(the "COMPANY"), and each of the purchasers listed on Schedule A attached hereto
(collectively, the "PURCHASERS" and individually, a "PURCHASER").

                                    RECITALS

         WHEREAS, the Company desires to sell to the Purchasers, and the
Purchasers desire to purchase from the Company, up to an aggregate of 23,333,350
shares of common stock, par value $.001 per share, of the Company ("COMMON
STOCK"), on the terms and conditions set forth in this Agreement; and

         WHEREAS, the Company and each Purchaser are executing and delivering
this Agreement in reliance upon exemption from securities registration afforded
by Regulation D ("REGULATION D") as promulgated by the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the
"SECURITIES ACT").

         NOW, THEREFORE, in consideration of the foregoing, the mutual promises
hereinafter set forth, and other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

         1. AGREEMENT TO PURCHASE AND SELL STOCK.

                  (a) Company Authorization. The Company's Board of Directors
has authorized the issuance and sale, pursuant to the terms and conditions of
this Agreement, of up to 23,333,350 shares of Common Stock (the "PURCHASED
SECURITIES").

                  (b) Agreement to Purchase and Sell Securities. Subject to the
terms and conditions of this Agreement, each Purchaser, severally and not
jointly, agrees to purchase, and the Company agrees to sell to each Purchaser,
at the Closing (as defined below), that number of Purchased Securities set forth
opposite such Purchaser's name on Schedule A attached hereto. The purchase price
of each of the Purchased Securities shall be $1.50 (the "PER SHARE PRICE") and
shall be payable as hereafter set forth.

                  (c) Use of Proceeds. The Company intends to use up to $10
million of the net proceeds from the sale of the Purchased Securities to
purchase shares of Common Stock from William A. Teitelbaum pursuant to that
certain Settlement Agreement and General Release by and among the Company, GVI
Security, Inc, William A. Teitelbaum and Alarmax Distributors, Inc., dated
October 13, 2004 (the "SETTLEMENT AGREEMENT"). The balance of the net proceeds
shall be used for working capital, general corporate purposes and the
acquisitions of businesses or assets as determined by the Company from time to
time.

                  (d) Obligations Several, Not Joint. The obligations of each
Purchaser under this Agreement are several and not joint with the obligations of
any other Purchaser, and no Purchaser shall be responsible in any way for the
performance of the obligations of any other Purchaser under this Agreement. The

<PAGE>

decision of each of the Purchasers to purchase the Purchased Securities pursuant
to this Agreement has been made by such Purchaser independently of any other
Purchaser. Nothing contained herein, and no action taken by any Purchaser
pursuant hereto, shall be deemed to constitute the Purchasers as a partnership,
an association, a joint venture or any other kind of entity, or create a
presumption that the Purchasers are in any way acting in concert or as a group
with respect to such obligations or the transactions contemplated by this
Agreement. Each Purchaser shall be entitled to independently protect and enforce
such Purchaser's rights, including, without limitation, the rights arising out
of this Agreement, and it shall not be necessary for any other Purchaser to be
joined as an additional party in any proceeding for such purpose.

         2. CLOSING. The purchase and sale of the Purchased Securities shall
take place at the offices of counsel for the Company, at 11:00 a.m. eastern
time, not later than two (2) Business Days (as defined below) following the
Execution Date, or at such other time and place as the Company and Purchasers
representing a majority of the Purchased Securities to be purchased, mutually
agree upon (which time and place are referred to in this Agreement as the
"CLOSING"). At the Closing, against delivery of full payment for the Purchased
Securities sold hereunder by wire transfer of immediately available funds in
accordance with the Company's instructions, the Company shall issue and deliver
to each Purchaser one or more stock certificates registered in the name of each
Purchaser (or in such nominee name(s) as designated by such Purchaser in the
Stock Certificate and Questionnaire, attached hereto as Appendix I, (the "STOCK
CERTIFICATE Questionnaire")), representing the number of Purchased Securities
set forth opposite the appropriate Purchaser's name on Schedule A hereto, and
bearing the legend set forth in Section 4(j) herein; provided, however, the
Company may furnish to each Purchaser a facsimile copy of the stock
certificate(s) representing the Purchased Securities purchased by such Purchaser
no later than the next Business Day following the Closing Date, with the
original stock certificate(s) to be delivered to such Purchaser by overnight
courier no later than the third (3rd) Business Day following the Closing Date.
Closing documents, other than the stock certificates representing the Purchased
Securities, may be delivered by facsimile on the Closing Date, with original
signature pages sent by overnight courier.

         For purposes of this Agreement, "CLOSING DATE" means the date of the
Closing, and "BUSINESS DAY" means any day except Saturday, Sunday and any day
which shall be a federal legal holiday or a day on which banking institutions in
the State of New York are authorized or required by law or other governmental
action to close.

         3. REPRESENTATIONS, WARRANTIES AND CERTAIN AGREEMENTS OF THE COMPANY.

<PAGE>

any lien, claim or encumbrance on any asset of the Company or the Subsidiaries

governmental bodies and agencies having jurisdiction over the Company's business
or properties, except for any instance of non-compliance that has not had, and
would not reasonably be expected to have, a Material Adverse Effect. Neither the
Company nor the Subsidiaries are in default (and there exists no condition
which, with or without the passage of time or giving of notice or both, would
constitute a default) in any material respect in the performance of any bond,
debenture, note or any other evidence of indebtedness in any indenture,
mortgage, deed of trust or any other material agreement or instrument to which
the Company or the Subsidiaries are a party or by which the Company or the
Subsidiaries are bound or by which the properties of the Company are bound,
which default would be reasonably likely to have a Material Adverse Effect or
which would be reasonably likely to have a Material Adverse Effect on the
transactions contemplated by this Agreement.

                  (k) Material Non-Public Information. Except as set forth in
the Disclosure Letter, the Company has not provided, and will not provide, to

                           (1) Reports. Since January 1, 2003, the Company has
filed all reports, schedules, forms, statements and other documents required to
be filed by it with the Securities and Exchange Commission (the "SEC") pursuant

reports on Form 10-QSB for the fiscal quarters ended March 31, 2004, June 30,
2004 and September 30, 2004 (the "FORM 10-QS"), and any Current Report on Form
8-K for events occurring since December 31, 2003 ("FORM 8-KS") filed by the
Company with the SEC (the Form 10-K, the Form 10-Qs and the Form 8-Ks are
collectively referred to herein as the "SEC DOCUMENTS"). Each of the SEC
Documents, as of the respective dates thereof (or, if amended or superseded by a
filing or submission, as the case may be, prior to the Closing Date, then on the
date of such filing or submission, as the case may be), (1) did not contain any
untrue statement of a material fact nor omit to state a material fact necessary
in order to make the statements made therein, in light of the circumstances
under which they were made, not misleading and (2) complied in all material
respects with the requirements of the Exchange Act and the rules and regulations
of the SEC promulgated thereunder applicable to such SEC Document.

                           (2) Sarbanes-Oxley. The chief executive officer and
the chief financial officer of the Company have signed, and the Company has
furnished to the SEC, all certifications required by Sections 302 and 906 of the
Sarbanes-Oxley Act of 2002. Such certifications contain no qualifications or
exceptions to the matters certified therein (other than such qualifications or
exceptions that are permitted under the Exchange Act and the rules promulgated
thereunder) and have not been modified or withdrawn; and neither the Company nor
any of its officers has received notice from any governmental entity questioning
or challenging the accuracy, completeness, form or manner of filing or
submission of such certifications. Without limiting the foregoing, the Company
is in compliance with any applicable requirements of the Sarbanes-Oxley Act of
2002 and the rules and regulations promulgated thereunder, as amended, that are
currently in effect, except where such noncompliance would not have or
reasonably be expected to result in a Material Adverse Effect or which would not
reasonably be expected to have a Material Adverse Effect on the transactions
contemplated by this Agreement.

                           (3) Financial Statements. The consolidated financial
statements of the Company included in the SEC Documents (1) comply in all
material respects with the rules and regulations of the SEC with respect thereto
as were in effect at the time of filing and (2) present fairly, in accordance
with United States generally accepted accounting principles ("GAAP"),
consistently applied, the consolidated financial position of the Company as of
the dates indicated therein, and the consolidated results of its operations and
cash flows for the periods therein specified, subject, in the case of unaudited
consolidated financial statements for interim periods, to normal, immaterial
year-end audit adjustments.

                  (m) Absence of Certain Changes Since the Balance Sheet Date
for the Company and the GVIS Subsidiary. Except as set forth in the Disclosure

acquisition by the Company or any subsidiary of the Company of any outstanding
shares of the Company's capital stock;

                           (ii) any damage, destruction or loss to the Company's

Effect;

                           (iii) any waiver by the Company or the GVIS
Subsidiary of a valuable right or of a material debt owed to it, except for such
waivers, individually and collectively, that have not had, and would not
reasonably be expected to have, a Material Adverse Effect;

waiver of any material right under a material contract or arrangement by which
the Company, the GVIS Subsidiary or any of their assets or properties is bound
or subject;

                           (v) any change by the Company in its accounting
principles, methods or practices or in the manner in which it keeps its
accounting books and records, except any such change required by a change in
GAAP or by the SEC; or

except for such events and conditions that have not resulted, and are not
expected to result, either individually or collectively, in a Material Adverse
Effect.

repurchase, redemption or other acquisition by the Rapor Subsidiary or any
subsidiary of the Rapor Subsidiary of any outstanding shares of the Rapor
Subsidiary's capital stock;

                           (ii) any damage, destruction or loss to the Rapor
Subsidiary's business or assets, whether or not covered by insurance, except for

Assuming the completion and timely delivery of the Registration
Statement/Suitability Questionnaire, attached hereto as Appendix II (the

Company is not aware of any facts or circumstances that would prohibit or delay
the preparation and filing of a registration statement with respect to the

Affiliate (as hereafter defined) of the Company, nor any person acting on its
behalf has, directly or indirectly, made any offers or sales of any security or
solicited any offers to buy any security, under circumstances that would cause
this offering of the Purchased Securities to be integrated with prior offerings

                                      -9-
<PAGE>

by the Company for purposes of the Securities Act, any applicable state

                  (z) Market. Other than public corporate communications and
filings with the Securities Exchange Commission that do not contain an
intentional misstatement or omission of a material fact, the Company has not
taken and will not take, directly or indirectly, any action designed to or that
might reasonably be expected to cause or result in the stabilization or
manipulation of the price of Common Stock of the Company or facilitate the sale
or resale of the Purchased Securities, however, the Company makes no
representation with respect to any action taken by C.E. Unterberg, Towbin, LLC
or its Affiliates

                  (aa) Investment Company. The Company is not an "investment
company" within the meaning of such term under the Investment Company Act of
1940, as amended, and the rules and regulations of the SEC thereunder.

                  (bb) Application of Anti-Takeover Provisions. There is no
control share acquisition, business combination, poison pill (including any
distribution under a rights agreement) or other similar anti-takeover provision
under the Company's Certificate of Incorporation (or similar charter documents)
that would become applicable to the Purchasers as a result of the issuance of
the Purchased Securities.

                  (cc) Trading and Registration Matters. The Common Stock of the
Company is eligible for price quotation and trading on the OTC Bulletin Board
Market under the symbol "GVIS". The Company has taken no action designed to
terminate, or likely to have the effect of terminating, the registration of the
Common Stock under the Exchange Act.

                  (dd) Settlement Agreement. The Settlement Agreement has been
duly and validly authorized, executed and delivered by the Company and the GVIS
Subsidiary and, to the Company's knowledge, the other parties thereto,
constitutes the valid and binding obligation of the Company and the GVIS
Subsidiary and, to the Company's knowledge, the other parties thereto and is
enforceable against the Company and the GVIS Subsidiary and, to the Company's
knowledge, the other parties in accordance with its terms. Neither party to the
Settlement Agreement is in breach of its obligations under the Settlement
Agreement and the Settlement Agreement is in full force and effect.

                  (ee) Press Releases. The press releases disseminated by the
Company during the twelve months preceding the date of this Agreement taken as a
whole do not contain any untrue statement of a material fact or omit to state a

                                      -10-
<PAGE>

material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made and
when made, not misleading.

                  (ff) Solvency. Based on the financial condition of the Company
as of the Closing Date (and assuming that the Closing shall have occurred), (i)
the Company's fair saleable value of its assets exceeds the amount that will be
required to be paid on or in respect of the Company's existing debts and other
liabilities (including known contingent liabilities) as they mature, (ii) the
Company's assets do not constitute unreasonably small capital to carry on its
business for the current fiscal year as now conducted and as proposed to be
conducted including its capital needs taking into account the particular capital
requirements of the business conducted by the Company, and projected capital
requirements and capital availability thereof, and (iii) the current cash flow
of the Company, together with the proceeds the Company would receive, were it to
liquidate all of its assets, after taking into account all anticipated uses of
the cash, would be sufficient to pay all amounts on or in respect of its debt
when such amounts are required to be paid. The Company does not intend to incur
debts beyond its ability to pay such debts as they mature (taking into account
the timing and amounts of cash to be payable on or in respect of its debt).

                  (gg) No Additional Agreements. The Company does not have any
agreement or understanding with any Purchaser with respect to the transactions
contemplated by the Agreement other than as specified in the Agreement.

         The Purchaser agrees that, to the extent necessary, the certificates
for the Purchased Securities shall bear the following legend:

                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                  "SECURITIES ACT") OR ANY APPLICABLE STATE SECURITIES LAWS, AND
                  MAY NOT BE SOLD OR TRANSFERRED UNLESS (I) A REGISTRATION

                                      -13-
<PAGE>

                  STATEMENT COVERING SUCH SECURITIES IS EFFECTIVE UNDER THE
                  SECURITIES ACT OR (II) THE TRANSACTION IS EXEMPT FROM
                  REGISTRATION UNDER THE SECURITIES ACT AND, IF THE COMPANY
                  REQUESTS, AN OPINION SATISFACTORY TO THE COMPANY TO SUCH
                  EFFECT HAS BEEN RENDERED BY COUNSEL."

         The Company acknowledges and agrees that Purchaser may from time to
time pledge pursuant to a bona fide margin agreement with a registered
broker-dealer or grant a security interest in some or all of the Purchased
Securities to a financial institution that is an "accredited investor" under
Regulation D and who agrees to be bound by the provisions of this Agreement and,
if required under the terms of such arrangement, in accordance with applicable
law such Purchaser may transfer pledged or secured Purchased Securities to the
pledgees or secured parties. Such a pledge or transfer would not be subject to
approval of the Company and no legal opinion of legal counsel of the pledgee,
secured party or pledgor shall be required in connection therewith. Further, no
notice shall be required of such pledge. At the expense of the Purchaser who
shall have pledged or otherwise granted a security interest in its Purchased
Securities, the Company will execute and deliver such reasonable documentation
as a pledgee or secured party of Purchased Securities may reasonably request in
connection with a pledge or transfer of the Purchased Securities, the
preparation and filing of any required prospectus supplement under Rule
424(b)(3) under the Securities Act or other applicable provision of the
Securities Act to appropriately amend the list of selling stockholders
thereunder.

         Certificates evidencing the Purchased Securities shall not contain any
legend, (i) following any sale of such Purchased Securities pursuant to a
registration statement (including the Registration Statement) covering such sale
that is effective under the Securities Act, (ii) following any sale of such
Purchased Securities pursuant to Rule 144, (iii) if such Purchased Securities
are eligible for sale under Rule 144(k) or (iv) if such legend is not required
under applicable requirements of the Securities Act (including judicial
interpretations and pronouncements issued by the Staff of the SEC). The Company
shall cause its counsel to issue a legal opinion to the Company's transfer agent
promptly after the date on which the Registration Statement is declared
effective (the "EFFECTIVE DATE") and such legend is no longer required under
this Section 4(j) if such legal opinion is required by the Company's transfer
agent to effect the removal of the legend hereunder. The Company agrees that at
such time as such legend is no longer required under this Section 4(j), it will,
no later than five (5) Business Days following the delivery by a Purchaser to
the Company or to the Company's transfer agent of a certificate representing
Purchased Securities issued with a restrictive legend, provide written
instructions to Company's transfer agent instructing the transfer agent to
deliver to such Purchaser a certificate representing such Purchased Securities
that is free from all restrictive and other legends. Except as may be required
by law, the Company may not make any notation on its records or give
instructions to any transfer agent of the Company that enlarge the restrictions
on transfer set forth in Section 4(i) or this Section 4(j).

         Each Purchaser, severally and not jointly with the other Purchasers,
agrees that the removal of the restrictive legend from certificates representing
the Purchased Securities as set forth in this Section 4(j) is predicated upon
the Purchaser's covenant that the Purchaser only will sell any Purchased

                                      -14-
<PAGE>

Securities pursuant to either the registration requirements of the Securities
Act, including any applicable prospectus delivery requirements, or an exemption
therefrom.

         In addition, the Purchaser agrees that the Company may place stop
transfer orders with its transfer agent with respect to such certificates in
order to implement the restrictions on transfer set forth in this Agreement. The
appropriate portion of the legend and the stop transfer orders will be removed
promptly upon delivery to the Company of such satisfactory evidence as
reasonably may be required by the Company that such legend or stop transfer
orders are not required to ensure compliance with the Securities Act.

                  (k) Questionnaires. The Purchaser has completed or caused to
be completed the Stock Certificate Questionnaire and the Registration Statement
Questionnaire for use in preparation of the Registration Statement (as defined
in Section 5(a) below) or a registration statement with respect to which the
Purchaser has exercised its rights pursuant to Section 5(i) below, and the
answers to such questionnaires are true and correct as of the date of this
Agreement; provided, that the Purchasers shall be entitled to update such
information by providing written notice thereof to the Company before the
effective date of the Registration Statement or a registration statement with
respect to which the Purchaser has exercised its rights pursuant to Section 5(i)
below.

                  (l) Restrictions on Short Sales. Neither the Purchaser nor any

contemplated hereby, (ii) has or shares discretion relating to such Purchaser's
investments or trading or information concerning such Purchaser's investments,
including in respect of the Purchased Securities, or (iii) is subject to such

Affiliate of such Purchaser is acting in the capacity of a broker-dealer
executing unsolicited third-party transactions.

                  (m) Independent Investment. The Purchaser has not agreed to
act with any other Purchaser for the purpose of acquiring, holding or disposing
of any of the Purchased Securities for purposes of Section 13(d) of the Exchange
Act, and such Purchaser is acting independently with respect to its investment

from the SEC, then the Company will use its commercially reasonable efforts to
cause the Registration Statement become effective as soon as commercially
practicable after the receipt by the Company of such SEC notification. In the
event that, following the Closing Date and prior to the end of the Registration
Period, the Company meets the requirements for the use of Form S-3, the Company
may, in its discretion, convert the Form SB-2 into Form S-3, or file a
replacement registration statement on Form S-3, promptly after the first date on
which it meets such requirements;

                           (iii) prepare and file with the SEC such amendments
(including post-effective amendments) and supplements to the Registration
Statement and the Prospectus (as defined below) used in connection therewith as
may be necessary to keep the Registration Statement effective at all times until
the end of the Registration Period;

                                      -16-
<PAGE>

                           (iv) furnish to the Purchasers, with respect to the
Registrable Shares registered under the Registration Statement, such reasonable
number of copies of any prospectus in conformity with the requirements of the
Securities Act and such other documents as the Purchasers may reasonably request
in writing, in order to facilitate the public sale or other disposition of all
or any of the Registrable Shares by the Purchasers;

                           (v) use its commercially reasonable efforts to file
documents required of the Company for normal blue sky clearance in states
specified in writing by the Purchasers; provided, however, that the Company
shall not be required to qualify to do business or consent to service of process
in any jurisdiction in which it is not now so qualified or has not so consented;

                           (vi) promptly notify the Purchasers in writing of the
effectiveness of the Registration Statement within one business day of the
Registration Statement being declared effective;

                           (vii) promptly notify the Purchasers in writing of
the existence of any fact or the happening of any event, during the Registration
Period (but not as to the substance of any such fact or event), that makes any
statement of a material fact made in the Registration Statement, the Prospectus,
any amendment or supplement thereto, or any document incorporated by reference
therein untrue, or that requires the making of any additions to or changes in
the Registration Statement or the Prospectus in order to make such statements
not misleading; provided, however, that no notice by the Company shall be
required pursuant to this subsection (vii) in the event that the Company either
contemporaneously files a prospectus supplement to update the Prospectus or, if
applicable, a Current Report on Form 8-K or other appropriate Exchange Act
report that is incorporated by reference into the Registration Statement, which,
in either case, contains the requisite information with respect to such material
event that results in such Registration Statement no longer containing any such
untrue or misleading statements;

                           (viii) bear all expenses in connection with the
procedures described in paragraphs (i) through (vii) of this Section 5(a) and
the registration of the Registrable Shares pursuant to the Registration
Statement, other than fees and expenses, if any, of legal counsel or other
advisers to the Purchasers or underwriting discounts, brokerage fees and
commissions incurred by the Purchasers, if any.

         It shall be a condition precedent to the obligations of the Company to
take any action pursuant to this Section 5(a) with respect to Registrable Shares
held by a Purchaser that such Purchaser shall timely furnish to the Company a
completed Registration Statement Questionnaire on or before the Closing Date and
such other written information regarding such Purchaser, the Registrable Shares
to be sold by such Purchaser and the intended method of disposition of the
Registrable Shares as the Company may deem necessary or advisable to effect the
registration of the Registrable Shares. The Purchasers shall update such
information as and when necessary by written notice to the Company.

                  (b) Liquidated Damages.

                           (i) Delay in Filing or Effectiveness of Registration
Statement. In the event that the Registration Statement is not (A) filed by the
Required Filing Date or (B) declared effective by the Required Effective Date,

                                      -17-
<PAGE>

the Company shall pay in cash to each Purchaser (except for any Purchaser whose
failure to provide information as required hereunder causes a delay in filing or
obtaining effectiveness) liquidated damages (in addition to the rights and
remedies available to each Purchaser under applicable law and this Agreement),
at a rate equal to one percent (1%) per month (pro rata on a 30-day basis) of
the product of the Per Share Price and the number of Purchased Securities held
by such Purchaser for the period from and including the first day following the
Required Filing Date or the Required Effective Date, as the case may be, until,
but excluding, the date that the Company files the Registration Statement with
the SEC or the date that the SEC declares the Registration Statement effective,
as the case may be. Such liquidated damages shall be payable in cash within ten
(10) days of the end of each one (1) month anniversary of the Required Filing
Date or the Required Effective Date, as the case may be.

                           (ii) Lapse in Effectiveness of Registration
Statement. In the event that the Registration Statement is filed and declared
effective but, during the Registration Period, the Registration Statement ceases
to be effective or useable or the prospectus included in the Registration
Statement (the "PROSPECTUS", as amended or supplemented by any prospectus
supplement and by all other amendments thereto and all material incorporated by
reference in such Prospectus) ceases to be usable, in either case, in connection
with resales of Registrable Shares, without such lapse being cured within
fifteen (15) Business Days (the "CURE PERIOD") by a post-effective amendment to
the Registration Statement, a supplement to the Prospectus or a report filed
with the SEC pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act
that cures such lapse, then except with respect to "Excluded Events" (defined
below), the Company shall pay in cash to each Purchaser liquidated damages (in
addition to the rights and remedies available to each Purchaser under applicable
law and this Agreement), for the period from and including the first day
following the expiration of the Cure Period until, but excluding, the earlier of
(1) the date on which such failure is cured and (2) the date on which the
Registration Period expires, at a rate equal to one percent (1%) per month (pro
rata on a 30-day basis) of the total product of the Per Share Price and the
number of Purchased Securities held by such Purchaser pursuant to this
Agreement. Such liquidated damages shall be payable in cash within ten (10) days
of the end of each one (1) month anniversary of the expiration of the Cure
Period. Excluded Events shall mean:

         (A)      as provided in Section 5(c)(ii) or 5(c)(iii) below,

         (B)      if the Company is involved in a Rule 13e-3 transaction as
                  defined in Section 13e-3 of the Exchange Act, or

         (C)      a merger or consolidation of the Company or sale of more than
                  one-half of the assets of the Company in one or a series of
                  related transactions, unless following such transaction or
                  series of transactions, the holders of the Company's
                  securities prior to the first such transaction continue to
                  hold at least 50% of the voting rights and equity interests of
                  the surviving entity or acquirer.

                  (c) Transfer of Registrable Shares After Registration;
Suspension.

                           (i) The Purchasers agree that they will not offer to
sell or make any sale, assignment, pledge, hypothecation or other transfer with
respect to the Registrable Shares that would constitute a sale within the
meaning of the Securities Act except pursuant to either (1) the Registration

                                      -18-
<PAGE>

Statement in the manner described in the "Plan of Distribution" therein, (2)
Rule 144 of the Securities Act or (3) any other exemption from registration
under the Securities Act, and that they will promptly notify the Company of any
changes in the information set forth in the Registration Statement after it is
prepared regarding the Purchaser or its plan of distribution to the extent
required by applicable law.

                           (ii) In addition to any suspension rights under
paragraph (iii) below, notwithstanding anything in this Agreement to the
contrary, upon the happening of any pending corporate development, public filing
with the SEC or similar event that, in the judgment of the Board of Directors,
renders it advisable to suspend the use of the Prospectus or upon the request by
an underwriter in connection with an underwritten public offering of the
Company's securities, the Company may for not more than forty-five (45) days
during any 12-month period suspend use of the Prospectus on written notice to
each Purchaser (which notice will not disclose the content of any material
non-public information and will indicate the date of the beginning and end of
the intended period of suspension, if known), in which case each Purchaser shall
discontinue any disposition of Registrable Shares covered by the Registration
Statement or Prospectus until copies of a supplemented or amended Prospectus are
distributed to the Purchasers or until the Purchasers are advised in writing by
the Company that sales of Registrable Shares under the applicable Prospectus may
be resumed and have received copies of any additional or supplemental filings
that are incorporated or deemed incorporated by reference in any such
Prospectus; provided, however, that no single suspension under this Section
5(c)(ii) may last longer than fifteen (15) days. The suspension and notice
thereof described in this Section 5(c)(ii) shall be held by each Purchaser in
strictest confidence and shall not be disclosed by such Purchaser.

                           (iii) Subject to paragraph (iv) below, in the event
of: (1) any request by the SEC or any other federal or state governmental
authority during the Registration Period for amendments or supplements to a
Registration Statement or related prospectus or for additional information; (2)
the issuance by the SEC or any other federal or state governmental authority of
any stop order suspending the effectiveness of a Registration Statement or the
initiation of any proceedings for that purpose; (3) 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 Shares for sale in any
jurisdiction or the initiation of any proceeding for such purpose; or (4) any
event or circumstance (other than those described described in Section 5(c)(ii)
above) which necessitates the making of any changes in the Registration
Statement or Prospectus, or any document incorporated or deemed to be
incorporated therein by reference, so that, in the case of the Registration
Statement, it will not contain any untrue statement of a material fact or any
omission to state a material fact required to be stated therein or necessary to
make the statements therein not misleading, and that in the case of the
Prospectus, it will not contain any untrue statement of a material fact or any
omission to state a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading, then the Company shall deliver a certificate in
writing to the Purchasers (the "SUSPENSION NOTICE") to the effect of the
foregoing (which notice will not disclose the content of any material non-public
information and will indicate the date of the beginning and end of the intended
period of suspension, if known), and, upon receipt of such Suspension Notice,
the Purchasers will discontinue disposition of Registrable Shares covered by to
the Registration Statement or Prospectus (a "SUSPENSION") until the Purchasers'

                                      -19-
<PAGE>

receipt of copies of a supplemented or amended Prospectus prepared and filed by
the Company, or until the Purchasers are advised in writing by the Company that
the current Prospectus may be used and have received copies of any additional or
supplemental filings that are incorporated or deemed incorporated by reference
in any such prospectus. In the event of any Suspension, the Company will use its
commercially reasonable efforts to cause the use of the Prospectus so suspended
to be resumed as soon as possible after delivery of a Suspension Notice to the
Purchasers. The Suspension and Suspension Notice described in this Section
5(c)(iii) shall be held in strictest confidence by each Purchaser and shall not
be disclosed by such Purchaser.

                           (iv) Provided that a Suspension is not then in
effect, the Purchasers may sell Registrable Shares under the Registration
Statement, provided that the selling Purchaser arranges for delivery of a
current Prospectus to the transferee of such Registrable Shares to the extent
such delivery is required by applicable law.

                           (v) In the event of a sale of Registrable Shares by a
Purchaser, such Purchaser must also deliver to the Company's transfer agent,
with a copy to the Company, a certificate of subsequent sale reasonably
satisfactory to the Company, so that ownership of the Registrable Shares may be
properly transferred. The Company will cooperate to facilitate the timely
preparation and delivery of certificates (unless otherwise required by
applicable law) representing Registrable Shares sold.

                  (d) Indemnification. For the purpose of this Section 5(d), the
term "REGISTRATION STATEMENT" shall include any preliminary or final Prospectus,
exhibit, supplement or amendment included in or relating to the Registration
Statement referred to in Sections 5(a) or 5(i).

                           (i) Indemnification by the Company. The Company
agrees to indemnify and hold harmless each of the Purchasers, their respective
officers, directors, agents and employees, and each person, if any, who controls
any Purchaser within the meaning of the Securities Act, against any losses,
claims, damages, liabilities or expenses, joint or several, to which such
Purchasers, such officers, directors, agents or employees, or such controlling
persons may become subject, under the Securities Act, the Exchange Act or any
other federal or state statutory law or regulation, or at common law or
otherwise (including in settlement of any litigation, if such settlement is
effected with the written consent of the Company, which consent shall not be
unreasonably withheld), insofar as such losses, claims, damages, liabilities or
expenses (or actions in respect thereof as contemplated below) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in the Registration Statement, the Prospectus, or any amendment
or supplement to the Registration Statement or Prospectus, or arise out of or
are based upon (i) the omission or alleged omission to state in any of them a
material fact required to be stated therein or necessary to make the statements
in any of them, in light of the circumstances under which they were made, not
misleading or (ii) any inaccuracy in or breach of the representations and
warranties or covenants made by the Company herein, and will reimburse each
Purchaser, each of its respective directors, officers, agents and employees, and
each such controlling person for any reasonable documented out-of-pocket legal
and other expenses incurred by such Purchaser, such directors, officers, agents
or employees, or such controlling persons in connection with investigating,
defending, settling, compromising or paying any such loss, claim, damage,
liability, expense or action; provided, however, that the Company will not be

                                      -20-
<PAGE>

liable for any such case to the extent that any such loss, claim, damage,
liability, expense or action arises out of or is based upon (1) an untrue
statement or alleged untrue statement or omission or alleged omission in the
Registration Statement, the Prospectus or any amendment to or supplement of the
Registration Statement or the Prospectus made in reliance upon and in conformity
with written information furnished to the Company by or on behalf of the
Purchaser demanding such indemnification expressly for use in the Registration
Statement or the Prospectus, (2) the failure of such Purchaser to comply with
the covenants and agreements contained in this Agreement respecting resale of
the Purchased Securities or (3) the use by the Purchaser of an outdated
Prospectus or any Prospectus containing any untrue statement or omission of a
material fact required to make such statement not misleading after the Company
has notified the Purchaser in writing that the Prospectus is outdated or
contains such untrue statement or omission.

                           (ii) Indemnification by each Purchaser. Each
Purchaser agrees, severally and not jointly, to indemnify and hold harmless the
Company, each of the Company's directors, officers, agents and employees, and
each person, if any, who controls the Company within the meaning of the
Securities Act, against any losses, claims, damages, liabilities or expenses to
which the Company, the Company's directors, officers, agents or employees, or
any controlling persons may become subject, under the Securities Act, the
Exchange Act, or any other federal or state statutory law or regulation, or at
common law or otherwise (including in settlement of any litigation, if such
settlement is effected with the written consent of such Purchaser, which consent
shall not be unreasonably withheld) insofar as such losses, claims, damages,
liabilities or expenses (or actions in respect thereof as contemplated below)
arise out of or are based upon (i) any untrue or alleged untrue statement of any
material fact contained in the Registration Statement, the Prospectus, or any
amendment or supplement thereto, or 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, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in the Registration Statement, the Prospectus, or any
amendment or supplement thereto, in reliance upon and in conformity with written
information furnished to the Company by or on behalf of such Purchaser expressly
for use therein, or (ii) any inaccuracy in or breach of the representations,
warranties or covenants made by such Purchaser herein, and such Purchaser will
reimburse the Company, each of its directors, officers, agents and employees,
and any controlling persons for any reasonable legal and other expenses incurred
by the Company, its directors, officers, agents or employees, or any controlling
persons in connection with investigating, defending, settling, compromising or
paying any such loss, claim, damage, liability, expense or action; provided,
however, that such Purchaser shall not be liable for any such untrue or alleged
untrue statement or omission or alleged omission with respect to which such
Purchaser has delivered to the Company in writing a correction of such untrue or
alleged untrue statement or omission or alleged omission, before the occurrence
of the event from which such loss, claim, damage, liability or expense was
incurred. Notwithstanding the provisions of this Section 5(d), such Purchaser
shall not be liable for any indemnification obligation under this Agreement in
excess of the aggregate dollar amount of net proceeds received by such Purchaser
from the sale of the Registrable Shares pursuant to the Registration Statement.

                           (iii) Indemnification Procedure.

                                      -21-
<PAGE>

                                    (1) Promptly after receipt by an indemnified
party under this Section 5(d) of notice of the threat or commencement of any
action, such indemnified party will, if a claim in respect thereof is to be made
against an indemnifying party under this Section 5(d), promptly notify the
indemnifying party in writing of the claim and provide to the indemnifying party
copies of all written documents relating to such threatened or commenced action;
but the omission so to notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party for contribution or
otherwise under the indemnity agreement contained in this Section 5(d) or
otherwise, to the extent it is not prejudiced as a result of such failure.

                                    (2) In case any such action is brought
against any indemnified party and such indemnified party seeks or intends to
seek indemnity from an indemnifying party, the indemnifying party will be
entitled to participate in, and, to the extent that it may wish, jointly with
all other indemnifying parties similarly notified, to assume the defense thereof
with counsel reasonably satisfactory to such indemnified party; 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 there may be a conflict between the positions of the indemnifying
party and the indemnified party in conducting the defense of any such action or
that there may be legal defenses available to it or other indemnified parties
that are different from or additional to those available to the indemnifying
party, the indemnified party or parties shall have the right to select separate
counsel to assume such legal defenses and to otherwise participate in the
defense of such action on behalf of such indemnified party or parties. Upon
receipt of notice from the indemnifying party to such indemnified party of its
election so to assume the defense of such action and approval by the indemnified
party of counsel, the indemnifying party will not be liable to such indemnified
party under this Section 5(d) for any legal or other expenses subsequently
incurred by such indemnified party in connection with the defense thereof
unless:

                                             a) the indemnified party shall have
employed such counsel in connection with the assumption of legal defenses in
accordance with the proviso to the preceding sentence (it being understood,
however, that the indemnifying party shall not be liable for the expenses of
more than one separate counsel, reasonably approved by such indemnifying party,
representing all of the indemnified parties who are parties to such action); or

                                             b) the indemnifying party shall not
have employed counsel reasonably satisfactory to the indemnified party to
represent the indemnified party within a reasonable time after notice of
commencement of the action against the indemnified party,

in each of which cases the reasonable documented out-of-pocket fees and expenses
of counsel for the indemnified party shall be at the expense of the indemnifying
party.

                           (iv) Contribution. If the indemnification provided
for in this Section 5(d) is required by its terms but is for any reason held to
be unavailable to, or is otherwise insufficient to hold harmless, an indemnified
party under this Section 5(d) with respect to any losses, claims, damages,
liabilities or expenses referred to in this Agreement, then each indemnifying
party shall contribute to the amount paid or payable by such indemnified party
as a result of any losses, claims, damages, liabilities or expenses referred to
in this Agreement:

                                      -22-
<PAGE>

                                    (1) in such proportion as is appropriate to
reflect the relative faults of the Company and the Purchasers in connection with
the statements or omissions or inaccuracies in the representations and
warranties in this Agreement that resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations,
or

                                    (2) if the allocation provided by clause (1)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative faults referred to in clause (1) above but also
the relative benefits received by the Company and the Purchasers from the sale
of the Purchased Securities.

         The respective relative benefits received by the Company on the one
hand and each Purchaser on the other shall be deemed to be in the same
proportion as the amount to which the consideration paid by such Purchaser to
the Company pursuant to this Agreement for the Registrable Shares purchased by
such Purchaser that were sold pursuant to the Registration Statement bears to
the difference (the "DIFFERENCE") between the amount such Purchaser paid for the
Registrable Shares that were sold pursuant to the Registration Statement and the
amount received by such Purchaser from such sale. The relative fault of the
Company and each Purchaser 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 the Company or by such Purchaser and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid or payable by a party as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include, subject to the limitations set forth in Section 5(d)(iii),
any reasonable legal or other fees or expenses incurred by such party in
connection with investigating or defending any such action or claim. The
provisions set forth in Section 5(d)(iii) with respect to the notice of the
threat or commencement of any threat or action shall apply if a claim for
contribution is to be made under this Section 5(d)(iv); provided, however, that
no additional notice shall be required with respect to any threat or action for
which notice has been given under Section 5(d)(iii) for purposes of
indemnification. The Company and each Purchaser agree that it would not be just
and equitable if contribution pursuant to this Section 5(d)(iv) were determined
solely by pro rata allocation (even if the Purchasers were treated as one entity
for such purpose) or by any other method of allocation which does not take
account of the equitable considerations referred to in this paragraph.
Notwithstanding the provisions of this Section 5(d)(iv), no Purchaser shall be
required to contribute any amount in excess of the amount by which the
Difference exceeds the amount of any damages that such Purchaser has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. 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 is not guilty of such fraudulent
misrepresentation. The Purchasers' obligations to contribute pursuant to this
Section 5(d)(iv) are several and not joint.

                  (e) Rule 144 Information. For two years after the date of this
Agreement, the Company shall file all reports required to be filed by it under
the Securities Act and the Exchange Act and the rules and regulations
promulgated thereunder and shall take such further action to the extent required
to enable the Purchasers to sell the Purchased Securities pursuant to Rule 144
under the Securities Act (as such rule may be amended from time to time).

                                      -23-
<PAGE>

                  (f) Subsequent Registrations. Except with respect to
registration rights previously granted by the Company and described on Schedule
3(p), other than pursuant to the Registration Statement, prior to the Effective
Date, the Company may not file any registration statement (other than on Form
S-8 or any successor form) with the SEC with respect to any securities of the
Company.

                  (g) Listing of Securities. The Company agrees, (i) if the
Company applies to have the Common Stock traded on any other trading market, it
will include in such application the Purchased Securities, and will take such
other action as is necessary or desirable to cause the Purchased Securities to
be listed on such other trading market as promptly as possible, and (ii) it will
take all action reasonably necessary to continue the listing and trading of its
Common Stock on a trading market and will comply in all material respects with
the Company's reporting, filing and other obligations under the bylaws or rules
of the trading market.

                  (h) Replacement of Securities. If any certificate or
instrument evidencing any Purchased Securities is mutilated, lost, stolen or
destroyed, the Company shall issue or cause to be issued in exchange and
substitution for and upon cancellation thereof, or in lieu of and substitution
therefor, a new certificate or instrument, but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction and
customary and reasonable indemnity, if requested. The applicants for a new
certificate or instrument under such circumstances shall also pay any reasonable
third-party costs associated with the issuance of such replacement Purchased
Securities. If a replacement certificate or instrument evidencing any Purchased
Securities is requested due to a mutilation thereof, the Company may require
delivery of such mutilated certificate or instrument as a condition precedent to
any issuance of a replacement.

                  (i) Piggy-Back Registrations. If at any time during the
Registration Period there is not an effective Registration Statement covering
all of the Purchased Securities and the Company shall determine to prepare and
file with the SEC a registration statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act or their successor forms) or their then equivalents relating to
equity securities to be issued solely in connection with any acquisition of any
entity or business or equity securities issuable in connection with stock option
or other employee benefit plans, then the Company shall send to each Purchaser
written notice of such determination and, if within fifteen days after receipt
of such notice, any such Purchaser shall so request in writing, the Company
shall include in such registration statement all or any part of such Purchased
Securities such purchaser requests to be registered, subject to customary
underwriter cutbacks applicable to all holders of registration rights.

         It shall be a condition precedent to the obligations of the Company to
take any action pursuant to this Section 5(i) with respect to Registrable Shares
held by a Purchaser that such Purchaser shall timely furnish to the Company a
completed Registration Statement Questionnaire on or before the Closing Date and
such other written information regarding such Purchaser, the Registrable Shares

expenses) incurred by any party hereto in connection with the preparation,

regulations; and, provided further, that no such release may identify a

by law.

                  (n) Waivers. No waiver by any party to this Agreement of any
default with respect to any provision, condition or requirement of this
Agreement shall be deemed to be a continuing waiver in the future or a waiver of
any other provision, condition or requirement hereof, nor shall any delay or
omission of any party to exercise any right hereunder in any manner impair the
exercise of any such right accruing to it thereafter.

                  (o) Stock Splits, Dividends and other Similar Events. The
provisions of this Agreement shall be appropriately adjusted to reflect any
stock split, stock dividend, reorganization or other similar event that may

rights provided herein or granted by law, including recovery of damages, each

specific performance of any such obligation the defense that a remedy at law
would be adequate.
