Subsidiaries that are parties thereto and, to the Company's Knowledge, the other
parties thereto, enforceable in accordance with their terms, except to the
extent that enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar laws
affecting the enforcement of creditors' rights generally, and there exists no

ownership, use, validity or enforceability of any Intellectual Property or
Confidential Information of the Company and its Subsidiaries and the Company's

reasonably be expected to have a Material Adverse Effect.

indirectly, made any offers or sales of any Company security or solicited any

the transactions contemplated hereby or would require registration of the
Securities under the 1933 Act.

          4.25 Private Placement. Assuming the accuracy of the representations

partner.

          4.28 Internal Controls. The Company is in compliance in all material
respects with the provisions of the Sarbanes-Oxley Act of 2002 currently

<PAGE>

management's general or specific authorizations, (ii) transactions are recorded

GAAP and to maintain asset accountability, (iii) access to assets is permitted
only in accordance with management's general or specific authorization, and (iv)
the recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences. The Company has established disclosure controls and procedures (as
defined in 1934 Act Rules 13a-15(e) and 15d-15(e)) for the Company and designed
such disclosure controls and procedures to ensure that material information
relating to the Company, including the Subsidiaries, is made known to the
certifying officers by others within those entities, particularly during the
period in which the Company's most recently filed period report under the 1934
Act, as the case may be, is being prepared. The Company's certifying officers
have evaluated the effectiveness of the Company's disclosure controls and
procedures as of the end of the period covered by the most recently filed
periodic report under the 1934 Act (such date, the "Evaluation Date"). The
Company presented in its most recently filed periodic report under the 1934 Act
the conclusions of the certifying officers about the effectiveness of the
disclosure controls and procedures based on their evaluations as of the
Evaluation Date. Since the Evaluation Date, there have been no significant
changes in the Company's internal controls (as such term is defined in Item 308
of Regulation S-K). The Company maintains and will continue to maintain a
standard system of accounting established and administered in accordance with
GAAP and the applicable requirements of the 1934 Act.

information that constitutes or might constitute material, non-public
information. The written materials delivered to the Investors in connection with
the transactions contemplated by the Transaction Documents do not contain any
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements contained therein, in light of the circumstances
under which they were made, not misleading.

requisite corporate, partnership or limited liability company power and
authority to enter into and to consummate the transactions contemplated by the
Transaction Documents and to perform its other obligations thereunder.

          5.2 Authorization. The execution, delivery and performance by such
Investor of the Transaction Documents to which such Investor is a party have
been duly authorized and will each constitute the valid and legally binding
obligation of such Investor, enforceable against such Investor in accordance
with their respective terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability,
relating to or affecting creditors' rights generally.

          5.3 Purchase Entirely for Own Account. The Securities to be received
by such Investor hereunder will be acquired for such Investor's own account, not
as nominee or

                                       14

<PAGE>

agent, and not with a view to the resale or distribution of any part thereof in
violation of the 1933 Act, and such Investor has no present intention of
selling, granting any participation in, or otherwise distributing the same in
violation of the 1933 Act without prejudice, however, to such Investor's right
at all times to sell or otherwise dispose of all or any part of such Securities
in compliance with applicable federal and state securities laws. Nothing
contained herein shall be deemed a representation or warranty by such Investor
to hold the Securities for any period of time. Such Investor is not a
broker-dealer registered with the SEC under the 1934 Act or an entity engaged in
a business that would require it to be so registered. Such Investor is acquiring
the Securities in the ordinary course of business and does not have any
agreement or understanding, directly or indirectly, with any Person to
distribute any of the Securities in violation of the 1933 Act.

          5.4 Investment Experience. Such Investor acknowledges that it can bear

business and the terms and conditions of the offering of the Securities,
including the merits and risks of investing in the Securities. Such Investor
acknowledges receipt of copies of the SEC Filings. Neither such inquiries nor
any other due diligence investigation conducted by such Investor shall modify,
limit or otherwise affect such Investor's right to rely on the Company's
representations and warranties contained in this Agreement.

          5.6 Restricted Securities. Such Investor understands that the
Securities are characterized as "restricted securities" under the U.S. federal
securities laws inasmuch as they are being acquired from the Company in a
transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the 1933 Act only in certain limited circumstances. The Investor is familiar
with Rule 144 under the 1933 Act and understands the resale limitations imposed
thereunder.

          5.7 Legends. It is understood that, except as provided below,
certificates evidencing the Securities may bear the following or any similar

               (a) "The securities represented hereby may not be transferred
unless (i) such securities have been registered for sale pursuant to the
Securities Act of 1933, as amended, (ii) such securities may be sold pursuant to
Rule 144(k), or (iii) the Company has received an opinion of counsel reasonably
satisfactory to it that such transfer may lawfully be made without registration
under the Securities Act of 1933 or qualification under applicable state
securities laws."

               (b) If required by the authorities of any state in connection
with the issuance of sale of the Securities, the legend required by such state

Securities in connection with a bona fide margin agreement or other loan or
financing arrangement secured by the Securities and, if required under the terms
of such agreement, loan or arrangement, such Investor may transfer pledged or
secured Securities to the pledgees or secured parties. Except as may otherwise
be required by this Agreement, such a pledge or transfer would not be subject to
approval of the Company and no legal opinion of the pledgee, secured party or
pledgor shall be required in connection therewith. Further, no notice shall be
required of such pledge. At the appropriate Investor's expense, the Company will
execute and deliver such reasonable documentation as a pledgee or secured party
of Securities may reasonably request in connection with a pledge or transfer of
the Securities, including the preparation and filing of any required prospectus
supplement under Rule 424(b)(3) of the 1933 Act or other applicable provision of
the 1933 Act to appropriately amend the list of selling stockholders thereunder.

performance by any other party of its obligations under this Agreement or the
other Transaction Documents.

     7. Covenants and Agreements of the Company.

          7.1 Reservation of Common Stock. From and after the effectiveness of
the Amendment, the Company shall at all times reserve and keep available out of
its authorized but unissued shares of Common Stock, solely for the purpose of
providing for the conversion of the Notes and the exercise of the Warrants, such
number of shares of Common Stock as shall from time to time equal the Conversion
Shares issuable upon the due conversion of the Notes and the

                                       19

<PAGE>

Warrant Shares issuable upon the due exercise of the Warrants in accordance with
their respective terms.

          7.2 Intentionally Omitted.

          7.3 No Conflicting Agreements. The Company will not take any action,
enter into any agreement or make any commitment that would conflict or interfere
in any material respect with the Company's obligations to the Investors under
the Transaction Documents.

          7.4 Insurance. The Company shall not materially reduce the insurance
coverages described in Section 4.19.

          7.5 Compliance with Laws. The Company will comply in all material
respects with all applicable laws, rules, regulations, orders and decrees of all
governmental authorities.

          7.6 Listing of Underlying Shares and Related Matters. The Company
shall take all necessary action to cause the Conversion Shares and the Warrant
Shares to be listed on the Nasdaq Global Market no later than the Proposal Date.
Further, if the Company applies to have its Common Stock or other securities
traded on any other principal stock exchange or market, it shall include in such
application the Conversion Shares and the Warrant Shares and will take such
other action as is necessary to cause such Common Stock to be so listed. The
Company will use commercially reasonable efforts to continue the listing and
trading of its Common Stock on the Nasdaq Global Market and, in accordance,
therewith, will use commercially reasonable efforts to comply in all respects
with the Company's reporting, filing and other obligations under the bylaws or
rules of such market or exchange, as applicable.

          7.7 Termination of Covenants. The provisions of Sections 7.2 through
7.5 shall terminate and be of no further force and effect on the date on which
the Company's obligations under the Registration Rights Agreement to register or
maintain the effectiveness of any registration covering the Registrable
Securities (as such term is defined in the Registration Rights Agreement) shall
terminate.

          7.8 Removal of Legends. Upon the earlier of (i) registration for
resale pursuant to the Registration Rights Agreement or (ii) Rule 144(k)
becoming available, the Company shall (A) deliver to the transfer agent for the
Common Stock (the "Transfer Agent") irrevocable instructions that the Transfer
Agent shall reissue a certificate representing the Conversion Shares and the
Warrant Shares without legends upon receipt by such Transfer Agent of the
legended certificates for such shares or the Notes and/or the Warrants (or any
legended certificates previously issued for such shares), together with either
(1) a customary representation by the Investor that Rule 144(k) applies to the
shares of Common Stock represented thereby or (2) a statement by the Investor
that such Investor has sold the shares of Common Stock represented thereby in
accordance with the Plan of Distribution contained in the Registration Statement
therefor, and (B) cause its counsel to deliver to the Transfer Agent one or more
blanket opinions to the effect that the removal of such legends in such
circumstances may be effected under the 1933 Act. From and after the earlier of
such dates, upon an Investor's written request, the Company shall promptly cause
certificates representing previously issued

                                       20

<PAGE>

Conversion Shares or Warrant Shares to be replaced with certificates which do
not bear such restrictive legends, and Conversion Shares subsequently issued
upon due conversion of the Notes and Warrant Shares subsequently issued upon due
exercise of the Warrants shall not bear such restrictive legends provided the
provisions of either clause (i) or clause (ii) above, as applicable, are
satisfied with respect to such Conversion Shares and/or Warrant Shares. When the
Company is required to cause unlegended certificates to replace previously
issued legended certificates, if: (1) unlegended certificates are not delivered
to an Investor within three (3) Business Days of submission by that Investor of
legended certificate(s) and supporting documentation to the Transfer Agent as
provided above and (2) prior to the time such Conversion Shares and/or Warrant
Shares are received free from restrictive legends, the Investor, or any third
party on behalf of such Investor or for the Investor's account, purchases (in an
open market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by the Investor of such Conversion Shares and/or Warrant
Shares (a "Buy-In"), then the Company shall pay in cash to the Investor (for
costs incurred either directly by such Investor or on behalf of a third party)
the amount by which the total purchase price paid for Common Stock as a result
of the Buy-In (including brokerage commissions, if any) exceeds the proceeds
received by such Investor as a result of the sale to which such Buy-In relates.
The Investor shall provide the Company written notice indicating the amounts
payable to the Investor in respect of the Buy-In.

          7.9 Proxy Statement; Stockholders Meeting. (a) The Company shall take
all action necessary to call an annual meeting of its stockholders (the
"Stockholders Meeting"), which shall conclude not later than December 31, 2006
(the "Stockholders Meeting Deadline"), for the purpose of, among other things,
seeking approval of the Company's stockholders for the following proposals
(collectively, the "Proposals"): (i) the issuance and sale to the Investors of
the Conversion Shares and the Warrant Shares pursuant to Nasdaq Marketplace Rule
4350(i) and (ii) the Amendment. In connection therewith, the Company will, in
accordance with its customary practice for annual meetings, prepare and file
with the SEC proxy materials (including a proxy statement and form of proxy) for
use at the Stockholders Meeting and, after receiving and promptly responding to
any comments of the SEC thereon, shall mail such proxy materials to the
stockholders of the Company. Each Investor shall furnish in writing to the
Company such information relating to such Investor and its investment in the
Company as the Company may reasonably request for inclusion in the Proxy
Statement. The Company will comply with Section 14(a) of the 1934 Act and the
rules promulgated thereunder in relation to any proxy statement (as amended or
supplemented, the "Proxy Statement") and any form of proxy to be sent to the
stockholders of the Company in connection with the Stockholders Meeting, and the
Proxy Statement shall not, on the date that the Proxy Statement (or any
amendment thereof or supplement thereto) is first mailed to stockholders or at
the time of the Stockholders Meeting, contain any untrue statement of a material
fact or omit to state any material fact necessary in order to make the
statements made therein not false or misleading, or omit to state any material
fact necessary to correct any statement in any earlier communication with
respect to the solicitation of proxies or the Stockholders Meeting which has
become false or misleading. If the Company should discover at any time prior to
the Stockholders Meeting, any event relating to the Company or any of its
Subsidiaries or any of their respective affiliates, officers or directors that
is required to be set forth in a supplement or amendment to the Proxy Statement,
in addition to the Company's obligations under the 1934 Act, the Company will
promptly inform the Investors thereof.

                                       21

<PAGE>

               (a) Subject to their fiduciary obligations under applicable law
(as determined in good faith by the Company's Board of Directors after
consultation with the Company's outside counsel), the Company's Board of
Directors shall recommend to the Company's stockholders that the stockholders
vote in favor of the Proposals (the "Company Board Recommendation") and take all
commercially reasonable action (including, without limitation, the hiring of a
proxy solicitation firm of nationally recognized standing) to solicit the
approval of the stockholders for the Proposals unless the Board of Directors
shall have modified, amended or withdrawn the Company Board Recommendation
pursuant to the provisions of the immediately succeeding sentence. The Company
covenants that the Board of Directors of the Company shall not modify, amend or
withdraw the Company Board Recommendation unless the Board of Directors (after
consultation with the Company's outside counsel) shall determine in the good
faith exercise of its business judgment that maintaining the Company Board
Recommendation would violate its fiduciary duty to the Company's stockholders.
Whether or not the Company's Board of Directors modifies, amends or withdraws
the Company Board Recommendation pursuant to the immediately preceding sentence,
the Company shall in accordance with Section 146 of the Delaware General
Corporation Law and the provisions of its Certificate of Incorporation and
Bylaws, (i) take all action necessary to convene the Stockholders Meeting as
promptly as practicable, but no later than the Stockholders Meeting Deadline, to
consider and vote upon the approval of the Proposals and (ii) submit the
Proposals at the Stockholders Meeting to the stockholders of the Company for
their approval.

               (b) The Company shall file the Amendment with the Secretary of
State of the State of Delaware no later than the close of business on the date
the Proposals are approved by the Company's stockholders in accordance with this
Section 7.9.

          7.10 Delivery of Warrants. On the Proposal Date, the Company shall
issue and deliver to the Investors for no additional consideration the Warrants
in the amounts set forth opposite the Investors' names at the addresses set
forth opposite such Investors' names on the signature pages hereto.

     8. Survival and Indemnification.

          8.1 Survival. The representations, warranties, covenants and
agreements contained in this Agreement shall survive the Closing of the
transactions contemplated by this Agreement.

          8.2 Indemnification. The Company agrees to indemnify and hold harmless
each Investor and its Affiliates and their respective directors, officers,
employees and agents from and against any and all losses, claims, damages,
liabilities and expenses (including without limitation reasonable attorney fees
and disbursements and other expenses incurred in connection with investigating,
preparing or defending any action, claim or proceeding, pending or threatened
and the costs of enforcement thereof) (collectively, "Losses") to which such
Person may become subject as a result of any breach of representation, warranty,
covenant or agreement made by or to be performed on the part of the Company
under the Transaction Documents, and will reimburse any such Person for all such
amounts as they are incurred by such Person.

                                       22

<PAGE>

          8.3 Conduct of Indemnification Proceedings. Promptly after receipt by
any Person (the "Indemnified Person") of notice of any demand, claim or
circumstances which would or might give rise to a claim or the commencement of
any action, proceeding or investigation in respect of which indemnity may be
sought pursuant to Section 8.2, such Indemnified Person shall promptly notify
the Company in writing and the Company shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to such Indemnified
Person, and shall assume the payment of all fees and expenses; provided,
however, that the failure of any Indemnified Person so to notify the Company
shall not relieve the Company of its obligations hereunder except to the extent
that the Company is materially prejudiced by such failure to notify. In any such
proceeding, any Indemnified Person shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person unless: (i) the Company and the Indemnified Person shall
have mutually agreed to the retention of such counsel; or (ii) in the reasonable
judgment of counsel to such Indemnified Person representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. The Company shall not be liable for any settlement of
any proceeding effected without its written consent, which consent shall not be
unreasonably withheld, but if settled with such consent, or if there be a final
judgment for the plaintiff, the Company shall indemnify and hold harmless such
Indemnified Person from and against any loss or liability (to the extent stated
above) by reason of such settlement or judgment. Without the prior written
consent of the Indemnified Person, which consent shall not be unreasonably
withheld, the Company shall not effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party and indemnity could have been sought hereunder by such
Indemnified Party, unless such settlement includes an unconditional release of
such Indemnified Person from all liability arising out of such proceeding.

     9. Miscellaneous.

          9.1 Successors and Assigns. This Agreement may not be assigned by a
party hereto without the prior written consent of the Company or the Investors,
as applicable, provided, however, that an Investor may assign its rights and
delegate its duties hereunder in whole or in part to an Affiliate or to a third
party acquiring some or all of its Securities in a private transaction without
the prior written consent of the Company or the other Investors, after notice
duly given by such Investor to the Company provided, that no such assignment or
obligation shall affect the obligations of such Investor hereunder. The
provisions of this Agreement shall inure to the benefit of and be binding upon
the respective permitted successors and assigns of the parties. Nothing in this
Agreement, express or implied, is intended to confer upon any party other than
the parties hereto or their respective successors and assigns any rights,
remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement.

          9.2 Counterparts; Faxes. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. This Agreement may also
be executed via facsimile, which shall be deemed an original.

jointly, pay their pro rata share of the reasonable attorneys' fees and other
reasonable out-of-pocket costs and expenses incurred by the prevailing party in
such proceedings.

          9.6 Amendments and Waivers. Any term of this Agreement may be amended
and the observance of any term of this Agreement may be waived (either generally
or in a particular instance and either retroactively or prospectively), only
with the written consent of the Company and the Investors. Any amendment or
waiver effected in accordance with this

                                       24

<PAGE>

paragraph shall be binding upon each holder of any Securities purchased under

Securities, and the Company.

          9.7 Publicity. Except as set forth below, no public release or
announcement concerning the transactions contemplated hereby shall be issued by
the Company or the Investors without the prior consent of the Company (in the
case of a release or announcement by the Investors) or the Investors (in the
case of a release or announcement by the Company) (which consents shall not be
unreasonably withheld), except as such release or announcement may be required
by law or the applicable rules or regulations of any securities exchange or
securities market, in which case the Company or the Investors, as the case may
be, shall allow the Investors or the Company, as applicable, to the extent
reasonably practicable in the circumstances, reasonable time to comment on such
release or announcement in advance of such issuance. By 8:30 a.m. (New York City
time) on the Trading Day immediately following the Closing Date, the Company
shall issue a press release disclosing the consummation of the transactions
contemplated by this Agreement. No later than the fourth Trading Day following
the Closing Date, the Company will file a Current Report on Form 8-K attaching
the press release described in the foregoing sentence as well as copies of the
Transaction Documents. In addition, the Company will make such other filings and
notices in the manner and time required by the SEC or Nasdaq. Notwithstanding
the foregoing, the Company shall not publicly disclose the name of any Investor,
or include the name of any Investor in any filing with the SEC (other than the
Registration Statement and any exhibits to filings made in respect of this
transaction in accordance with periodic filing requirements under the 1934 Act)
or any regulatory agency or Nasdaq, without the prior written consent of such
Investor, except to the extent such disclosure is required by law or trading
market regulations, in which case the Company shall provide the Investors with
prior notice of such disclosure.

          9.8 Severability. Any provision of this Agreement that is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof but shall be interpreted as if it
were written so as to be enforceable to the maximum extent permitted by
applicable law, and any such prohibition or unenforceability in any jurisdiction
shall not invalidate or render unenforceable such provision in any other
jurisdiction. To the extent permitted by applicable law, the parties hereby
waive any provision of law which renders any provision hereof prohibited or
unenforceable in any respect.

          9.9 Entire Agreement. This Agreement, including the Exhibits and the
Disclosure Schedules, and the other Transaction Documents constitute the entire
agreement among the parties hereof with respect to the subject matter hereof and
thereof and supersede all prior agreements and understandings, both oral and
written, between the parties with respect to the subject matter hereof and
thereof.

          9.10 Further Assurances. The parties shall execute and deliver all
such further instruments and documents and take all such other actions as may

                                       25

<PAGE>

          9.11 Governing Law; Consent to Jurisdiction; Waiver of Jury Trial.
This Agreement shall be governed by, and construed in accordance with, the
internal laws of the State of New York without regard to the choice of law
principles thereof. Each of the parties hereto irrevocably submits to the
exclusive jurisdiction of the courts of the State of New York located in New
York County and the United States District Court for the Southern District of
New York for the purpose of any suit, action, proceeding or judgment relating to
or arising out of this Agreement and the transactions contemplated hereby.
Service of process in connection with any such suit, action or proceeding may be
served on each party hereto anywhere in the world by the same methods as are
specified for the giving of notices under this Agreement. Each of the parties
hereto irrevocably consents to the jurisdiction of any such court in any such
suit, action or proceeding and to the laying of venue in such court. Each party
hereto irrevocably waives any objection to the laying of venue of any such suit,
action or proceeding brought in such courts and irrevocably waives any claim
that any such suit, action or proceeding brought in any such court has been
brought in an inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO
REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND
REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

          9.12 Independent Nature of Investors' Obligations and Rights. The
obligations of each Investor under any Transaction Document are several and not
joint with the obligations of any other Investor, and no Investor shall be
responsible in any way for the performance of the obligations of any other
Investor under any Transaction Document. The decision of each Investor to
purchase Securities pursuant to the Transaction Documents has been made by such
Investor independently of any other Investor. Nothing contained herein or in any
Transaction Document, and no action taken by any Investor pursuant thereto,
shall be deemed to constitute the Investors as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Investors are in any way acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Documents. Each
Investor acknowledges that no other Investor has acted as agent for such
Investor in connection with making its investment hereunder and that no Investor
will be acting as agent of such Investor in connection with monitoring its
investment in the Securities or enforcing its rights under the Transaction
Documents. Each Investor shall be entitled to independently protect and enforce
its rights, including, without limitation, the rights arising out of this
Agreement or out of the other Transaction Documents, and it shall not be
necessary for any other Investor to be joined as an additional party in any
proceeding for such purpose. The Company acknowledges that each of the Investors
has been provided with the same Transaction Documents for the purpose of closing
a transaction with multiple Investors and not because it was required or
requested to do so by any Investor.

the certificate or certificates for the Conversion Shares issuable upon such
conversion shall be issued. Promptly following the surrender of this Note (or,
in lieu thereof, delivery of an appropriate lost security affidavit in the event
this Note shall have been lost or destroyed, together with a customary indemnity
agreement) as aforesaid, but in no event more than three (3) Business Days
thereafter, the Company shall issue and deliver, or cause to be issued and
delivered, to the Holder, registered in such name or names as the Holder may
direct in writing, a certificate or certificates for the number of whole
Conversion Shares issuable upon the conversion of this Note and, in the case of
an optional conversion of less than the entire amount of this Note, a new note
of like tenor in the principal amount of this Note not being converted on the
relevant Optional Conversion Date. To the extent permitted by law, such
conversion shall be deemed to have been effected, and the Conversion Price shall
be determined, as of the close of business on the Automatic Conversion Date or
the Optional Conversion Date, as applicable, and at such time, the rights of the
Holder shall cease with respect to the Note, or amount thereof, being converted,
and the Person or Persons in whose name or names any certificate or certificates
for Conversion Shares shall be issuable upon such conversion shall be deemed to
have become the holder or holders of record of the Conversion Shares represented
thereby.

          (d) No fractional shares shall be issued upon any conversion of this
Note into Common Stock. If any fractional share of Common Stock would, except
for the provisions of the first sentence of this Section 4(d), be delivered upon
such conversion, the Company, in lieu of delivering such fractional share, shall
pay to the Holder an amount in cash equal to the Market Price of such fractional
share of Common Stock.

          (e) If the Company shall, at any time or from time to time while this
Note is outstanding, pay a dividend or make a distribution on its Common Stock
in shares of Common Stock, subdivide its outstanding shares of Common Stock into
a greater number of shares or combine its outstanding shares of Common Stock
into a smaller number of shares or issue by reclassification of its outstanding
shares of Common Stock any shares of its capital stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing corporation), then (i) the Conversion Price in effect
immediately prior to the date on which such change shall become effective shall
be adjusted by multiplying such Conversion Price by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such change and the denominator of which shall be the number of shares
of Common Stock outstanding immediately after giving effect to such change and
(ii) the number of Conversion Shares issuable upon conversion of this Note shall
be adjusted by multiplying the number of Conversion Shares issuable upon
conversion of this Note immediately prior to the date on which such change shall
become effective by a fraction, the numerator of which is shall be the
Conversion Price in effect immediately prior to the date on which such change
shall become effective and the denominator of which shall be the Conversion
Price in effect immediately after giving effect to such change, calculated in
accordance with clause (i) above. Such adjustments shall be made successively
whenever any event listed above shall occur.

                                      A-10

<PAGE>

          (f) If any capital reorganization, reclassification of the capital
stock of the Company, consolidation or merger of the Company with another
corporation in which the Company is not the survivor, or sale, transfer or other
disposition of all or substantially all of the Company's assets to another
Person shall be effected, then, as a condition of such reorganization,
reclassification, consolidation, merger, sale, transfer or other disposition,
lawful and adequate provision shall be made whereby the Holder shall thereafter
have the right, at its option, either (i) to purchase and receive upon the basis
and upon the terms and conditions herein specified and in lieu of the Conversion
Shares immediately theretofore issuable upon conversion of this Note such shares
of stock, securities or assets as would have been issuable or payable with
respect to or in exchange for a number of Conversion Shares equal to the number
of Conversion Shares immediately theretofore issuable upon conversion of this
Note, had such reorganization, reclassification, consolidation, merger, sale,
transfer or other disposition not taken place, and in any such case appropriate
provision shall be made with respect to the rights and interests of the Holder
to the end that the provisions hereof (including, without limitation, provision
for adjustment of the Conversion Price) shall thereafter be applicable, as
nearly equivalent as may be practicable in relation to any shares of stock,
securities or assets thereafter deliverable upon the conversion hereof or (ii)
in the event or any such consolidation or merger of the Company or such sale,
transfer or other disposition of all or substantially all of the Company's
assets only, to cause the Company to redeem this Note at a redemption price
equal to 110% of the outstanding principal amount of this Note, together with
all accrued and unpaid interest hereon to the date of redemption, which right
must be exercised by the Holder within ten (10) Business Days after receipt by
it from the Company of written notice of the occurrence of any transaction
giving rise to such right. The Company shall not effect any such consolidation,
merger, sale, transfer or other disposition unless prior to or simultaneously
with the consummation thereof the successor corporation (if other than the
Company) resulting from such consolidation or merger, or the corporation
purchasing or otherwise acquiring such assets or other appropriate corporation
or entity shall assume the obligation to deliver to the Holder, at the last
address of the Holder appearing on the books of the Company, such shares of
stock, securities or assets as, in accordance with the foregoing provisions, the
Holder may be entitled to purchase, without regard to any conversion limitation
specified in Section 4, and the other obligations under this Note. The
provisions of this paragraph (f) shall similarly apply to successive
reorganizations, reclassifications, consolidations, mergers, sales, transfers or
other dispositions.

          (g) In case the Company shall fix a payment date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness or assets (other than cash
dividends or cash distributions payable out of consolidated earnings or earned
surplus or dividends or distributions referred to in Section 4(e)), or
subscription rights or warrants, the Conversion Price to be in effect after such
payment date shall be determined by multiplying the Conversion Price in effect
immediately prior to such payment date by a fraction, the numerator of which
shall be the total number of shares of Common Stock outstanding multiplied by
the Market Price of Common Stock immediately prior to such payment date, less
the fair market value (as determined by the Board in good faith) of said assets
or evidences of indebtedness so distributed, or of such subscription rights or
warrants, and the denominator of which shall be the total number of shares of
Common Stock outstanding multiplied by such Market Price immediately prior to
such payment date. Such adjustment shall be made successively whenever such a
payment date is fixed.

                                      A-11

<PAGE>

          (h) An adjustment to the Conversion Price shall become effective
immediately after the payment date in the case of each dividend or distribution
and immediately after the effective date of each other event which requires an
adjustment.

          (i) In the event that, as a result of an adjustment made pursuant to
this Section 4, the Holder shall become entitled to receive any shares of
capital stock of the Company other than shares of Common Stock, the number of
such other shares so receivable upon conversion of this Note shall be subject
thereafter to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions contained in this Note.

          (j) Except as provided in Section 4(j) hereof, if and whenever the
Company shall issue or sell, or is, in accordance with any of Sections 4(j)(i)
through 4(j)(vii) hereof, deemed to have issued or sold, any Additional Shares
of Common Stock (as defined below) for no consideration or for a consideration
per share less than the Conversion Price in effect immediately prior to the time
of such issuance or sale, then and in each such case (a "Trigger Issuance") the
then-existing Conversion Price, shall be reduced, as of the close of business on
the effective date of the Trigger Issuance, to a price determined as follows:

          Adjusted Conversion Price = (A x B) + D
                                      -----------
                                        A+C

                    where

                    "A" equals the number of shares of Common Stock outstanding,
including Additional Shares of Common Stock (as defined below) deemed to be
issued hereunder, immediately preceding such Trigger Issuance;

                    "B" equals the Conversion Price in effect immediately
preceding such Trigger Issuance;

                    "C" equals the number of Additional Shares of Common Stock
issued or deemed issued hereunder as a result of the Trigger Issuance; and

                    "D" equals the aggregate consideration, if any, received or
deemed to be received by the Company upon such Trigger Issuance;

provided, however, that in no event shall the Conversion Price after giving
effect to such Trigger Issuance be greater than the Conversion Price in effect
prior to such Trigger Issuance.

          For purposes of this subsection (j), "Additional Shares of Common
Stock" shall mean all shares of Common Stock issued or sold by the Company or
deemed to be issued or sold pursuant to this subsection (j), other than Excluded
Issuances (as defined in subsection (k) hereof).

          For purposes of this Section 4(j), the following subsections (j)(i) to
(j)(viii) shall also be applicable (subject, in each such case, to the
provisions of Section 4(k) hereof):

                                      A-12

<PAGE>

          (i) In case at any time the Company shall in any manner grant
(directly and not by assumption in a merger or otherwise) any warrants or other
rights to subscribe for or to purchase, or any options for the purchase of,
Common Stock or any stock or security convertible into or exchangeable for
Common Stock (such warrants, rights or options being called "Options" and such
convertible or exchangeable stock or securities being called "Convertible
Securities") whether or not such Options or the right to convert or exchange any
such Convertible Securities are immediately exercisable, and the price per share
for which Common Stock is issuable upon the exercise of such Options or upon the
conversion or exchange of such Convertible Securities (determined by dividing
(i) the sum (which sum shall constitute the applicable consideration) of (x) the
total amount, if any, received or receivable by the Company as consideration for
the granting of such Options, plus (y) the aggregate amount of additional
consideration payable to the Company upon the exercise of all such Options, plus
(z), in the case of such Options which relate to Convertible Securities, the
aggregate amount of additional consideration, if any, payable upon the issuance
or sale of such Convertible Securities and upon the conversion or exchange
thereof, by (ii) the total maximum number of shares of Common Stock issuable
upon the exercise of such Options or upon the conversion or exchange of all such
Convertible Securities issuable upon the exercise of such Options) shall be less
than the Conversion Price immediately prior to the time of the granting of such
Options, then the total number of shares of Common Stock issuable upon the
exercise of such Options or upon conversion or exchange of the total amount of
such Convertible Securities issuable upon the exercise of such Options shall be
deemed to have been issued for such price per share as of the date of granting
of such Options or the issuance of such Convertible Securities and thereafter
shall be deemed to be outstanding for purposes of adjusting the Conversion
Price. Except as otherwise provided in subsection 4(i)(iii), no adjustment of
the Conversion Price shall be made upon the actual issuance of such Common Stock
or of such Convertible Securities upon exercise of such Options or upon the
actual issuance of such Common Stock upon conversion or exchange of such
Convertible Securities.

          (ii) In case the Company shall in any manner issue (directly and not
by assumption in a merger or otherwise) or sell any Convertible Securities,
whether or not the rights to exchange or convert any such Convertible Securities
are immediately exercisable, and the price per share for which Common Stock is
issuable upon such conversion or exchange (determined by dividing (i) the sum
(which sum shall constitute the applicable consideration) of (x) the total
amount received or receivable by the Company as consideration for the issuance
or sale of such Convertible Securities, plus (y) the aggregate amount of
additional consideration, if any, payable to the Company upon the conversion or
exchange thereof, by (ii) the total number of shares of Common Stock issuable
upon the conversion or exchange of all such Convertible Securities) shall be
less than the Conversion Price immediately prior to the time of such issuance or
sale, then the total maximum number of shares of Common Stock issuable upon
conversion or exchange of all such Convertible Securities shall be deemed to
have been issued for such price per share as of the date of the issuance or sale
of such Convertible Securities and thereafter shall be deemed to be outstanding
for purposes of adjusting the Conversion Price, provided that (a) except as
otherwise provided in subsection 4(j)(iii), no adjustment of the Conversion
Price shall be made upon the actual issuance of such Common Stock upon
conversion or exchange of such Convertible Securities and (b) no further
adjustment of the Conversion Price shall be made by reason of the issuance or
sale of Convertible Securities upon exercise of any Options to purchase any such
Convertible Securities for which adjustments of the Conversion Price have been
made pursuant to the other provisions of Section 4(j).

                                      A-13

<PAGE>

          (iii) Upon the happening of any of the following events, namely, if
the purchase price provided for in any Option referred to in subsection 4(j)(i)
hereof, the additional consideration, if any, payable upon the conversion or
exchange of any Convertible Securities referred to in subsections 4(j)(i) or
4(j)(ii), or the rate at which Convertible Securities referred to in subsections
4(j)(i) or 4(j)(ii) are convertible into or exchangeable for Common Stock shall
change at any time (including, but not limited to, changes under or by reason of
provisions designed to protect against dilution), the Conversion Price in effect
at the time of such event shall forthwith be readjusted to the Conversion Price
which would have been in effect at such time had such Options or Convertible
Securities still outstanding provided for such changed purchase price,
additional consideration or conversion rate, as the case may be, at the time
initially granted, issued or sold. On the termination of any Option for which
any adjustment was made pursuant to this subsection 4(j) or any right to convert
or exchange Convertible Securities for which any adjustment was made pursuant to
this subsection 4(j) (including without limitation upon the redemption or
purchase for consideration of such Convertible Securities by the Company), the
Conversion Price then in effect hereunder shall forthwith be changed to the
Conversion Price which would have been in effect at the time of such termination
had such Option or Convertible Securities, to the extent outstanding immediately
prior to such termination, never been issued.

          (iv) Subject to the provisions of this Section 4(j), in case the
Company shall declare a dividend or make any other distribution upon any stock
of the Company (other than the Common Stock) payable in Common Stock, Options or
Convertible Securities, then any Common Stock, Options or Convertible
Securities, as the case may be, issuable in payment of such dividend or
distribution shall be deemed to have been issued or sold without consideration;
provided, that if any adjustment is made to the Conversion Price as a result of
a declaration of a dividend and such dividend is rescinded, the Conversion Price
shall be appropriately readjusted to the Conversion Price in effect had such
dividend not been declared.

          (v) In case any shares of Common Stock, Options or Convertible
Securities shall be issued or sold for cash, the consideration received therefor
shall be deemed to be the net amount received by the Company therefor, after
deduction therefrom of any expenses incurred or any underwriting commissions or
concessions paid or allowed by the Company in connection therewith. In case any
shares of Common Stock, Options or Convertible Securities shall be issued or
sold for a consideration other than cash, the amount of the consideration other
than cash received by the Company shall be deemed to be the fair value of such
consideration as determined in good faith by the Board, after deduction of any
expenses incurred or any underwriting commissions or concessions paid or allowed
by the Company in connection therewith. In case any Options shall be issued in
connection with the issuance and sale of other securities of the Company,
together comprising one integral transaction in which no specific consideration
is allocated to such Options by the parties thereto, such Options shall be
deemed to have been issued for such consideration as determined in good faith by
the Board of Directors of the Company. If Common Stock, Options or Convertible
Securities shall be issued or sold by the Company and, in connection therewith,
other Options or Convertible Securities (the "Additional Rights") are issued,
then the consideration received or deemed to be received by the Company shall be
reduced by the fair market value of the Additional Rights (as determined using
the Black-Scholes option pricing model or another method mutually agreed to by
the Company and the Holder). The Board shall respond promptly, in writing, to an
inquiry by the Holder as to the

                                      A-14

<PAGE>

fair market value of the Additional Rights. In the event that the Board and the
Holder are unable to agree upon the fair market value of the Additional Rights,
the Company and the Holder shall jointly select an appraiser, who is experienced
in such matters. The decision of such appraiser shall be final and conclusive,
and the cost of such appraiser shall be borne evenly by the Company and the
Holder.

          (vi) In case the Company shall take a record of the holders of its
Common Stock for the purpose of entitling them (i) to receive a dividend or
other distribution payable in Common Stock, Options or Convertible Securities or
(ii) to subscribe for or purchase Common Stock, Options or Convertible
Securities, then such record date shall be deemed to be the date of the issuance
or sale of the shares of Common Stock deemed to have been issued or sold upon
the declaration of such dividend or the making of such other distribution or the
date of the granting of such right of subscription or purchase, as the case may
be.

          (vii) The number of shares of Common Stock outstanding at any given
time shall not include shares owned or held by or for the account of the Company
or any of its wholly-owned subsidiaries, and the disposition of any such shares
(other than the cancellation or retirement thereof) shall be considered an
issuance or sale of Common Stock for the purpose of this subsection (j).

          (viii) Notwithstanding any other provision in this subsection (j) to
the contrary, if a reduction in the Conversion Price pursuant to this subsection
(j) (other than as set forth in this clause (viii)) would require the Company to
obtain stockholder approval of the transactions contemplated by the Purchase
Agreement to be consummated on the Closing Date pursuant to Nasdaq Marketplace
Rule 4350(i) and such stockholder approval has not been obtained, (i) the
Conversion Price shall be reduced to the maximum extent that would not require
stockholder approval under such Rule, and (ii) the Company shall use its
commercially reasonable efforts to obtain such stockholder approval as soon as
reasonably practicable, including by calling a special meeting of stockholders
to vote on such Conversion Price adjustment. This provision shall not restrict
the number of shares of Common Stock which a Holder may receive or beneficially
own in order to determine the amount of securities or other consideration that
such Holder may receive in the event of a transaction contemplated by Section 4
of this Note.

          (k) Anything herein to the contrary notwithstanding, the Company shall
not be required to make any adjustment of the Conversion Price in the case of
the issuance of (A) capital stock, Options or Convertible Securities issued to
directors, officers, employees or consultants of the Company in connection with
their service as directors of the Company, their employment by the Company or
their retention as consultants by the Company pursuant to an equity compensation
program approved by the Board of Directors of the Company or the compensation
committee of the Board of Directors of the Company, (B) shares of Common Stock
issued upon the conversion or exercise of Options or Convertible Securities
issued prior to the date hereof, provided such securities are not amended after
the date hereof to increase the number of shares of Common Stock issuable
thereunder or to lower the exercise or conversion price thereof, (C) securities
issued pursuant to the Purchase Agreement and securities issued upon the
exercise or conversion of those securities, (D) shares of Common Stock issued or
issuable by reason of a dividend, stock split or other distribution on shares of
Common Stock (but only to the extent that such a dividend, split or distribution
results in an adjustment in the

                                      A-15

<PAGE>

Conversion Price pursuant to the other provisions of this Note) and (E)
securities issued pursuant to the PIPE Purchase Agreement (collectively,
"Excluded Issuances").

          (l) In case at any time:

          (i) the Company shall declare any dividend upon its Common Stock or
any other class or series of capital stock of the Company payable in cash or
stock or make any other distribution to the holders of its Common Stock or any
such other class or series of capital stock;

          (ii) the Company shall offer for subscription pro rata to the holders
of its Common Stock or any other class or series of capital stock of the Company
any additional shares of stock of any class or other rights; or

          (iii) there shall be any capital reorganization or reclassification of
the capital stock of the Company, any acquisition or a liquidation, dissolution
or winding up of the Company;

then, in any one or more of said cases, the Company shall give, by delivery in
person or by certified or registered mail, return receipt requested, addressed
to the Holder at the address of such Holder as shown on the books of the
Company, (a) at least 20 Business Days' prior written notice of the date on
which the books of the Company shall close or a record shall be taken for such
dividend, distribution or subscription rights or for determining rights to vote
in respect of any event set forth in clause (iii) of this Section 4(l) and (b)
in the case of any event set forth in clause (iii) of this Section 4(l), at
least 20 Business Days' prior written notice of the date when the same shall
take place. Such notice in accordance with the foregoing clause (a) shall also
specify, in the case of any such dividend, distribution or subscription rights,
the date on which the holders of Common Stock or such other class or series of
capital stock shall be entitled thereto and such notice in accordance with the
foregoing clause (b) shall also specify the date on which the holders of Common
Stock and such other series or class of capital stock shall be entitled to
exchange their Common Stock and other stock for securities or other property
deliverable upon consummation of the applicable event set forth in clause (iii)
of this Section 4(l).

          (m) Upon any adjustment of the Conversion Price, then and in each such
case the Company shall give prompt written notice thereof, by delivery in person
or by certified or registered mail, return receipt requested, addressed to the
Holder at the address of such Holder as shown on the books of the Company, which
notice shall state the Conversion Price resulting from such adjustment and
setting forth in reasonable detail the method upon which such calculation is
based.

          (n) From and after the effectiveness of the Amendment (as defined in
the Purchase Agreement), the Company shall at all times reserve and keep
available out of its authorized Common Stock, solely for the purpose of issuance
upon conversion of this Note as herein provided, such number of shares of Common
Stock as shall then be issuable upon the conversion of this Note. The Company
covenants that all shares of Common Stock which shall be so issued shall be duly
and validly issued and fully paid and nonassessable, and free from all taxes,
liens and charges with respect to the issue thereof, and, without limiting the
generality of the foregoing, and that the Company will from time to time take
all such action as may be

                                      A-16

<PAGE>

requisite to assure that the par value per share of the Common Stock is at all
times equal to or less than the Conversion Price in effect at the time. The
Company shall take all such action as may be necessary to assure that all such
shares of Common Stock may be so issued without violation of any applicable law
or regulation, or of any requirement of any national securities exchange or
trading market upon which the Common Stock may be listed. The Company shall not
take any action which results in any adjustment of the Conversion Price if the
total number of shares of Common Stock issued and issuable after such action
upon conversion of this Note would exceed the total number of shares of Common
Stock then authorized by the Company's Certificate of Incorporation.

          (o) The issuance of certificates for shares of Common Stock upon
conversion of this Note shall be made without charge to the holders thereof for
any issuance tax in respect thereof, provided that the Company shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any certificate in a name other than that of the
Holder. When the Company is required to issue Conversion Shares hereunder, if:
(1) certificates representing such Conversion Shares are not delivered to the
Holder within three (3) Business Days of the Automatic Conversion Date or the
Optional Conversion Date, as applicable, and (2) prior to the time such
certificates are received, the Holder, or any third party on behalf of such
Holder or for the Holder's account, purchases (in an open market transaction or
otherwise) shares of Common Stock to deliver in satisfaction of a sale by the
Holder of such certificates (a "Buy-In"), then the Company shall pay in cash to
the Holder (for costs incurred either directly by such Holder or on behalf of a
third party) the amount by which the total purchase price paid for Common Stock
as a result of the Buy-In (including brokerage commissions, if any) exceeds the
proceeds received by the Holder as a result of the sale to which such Buy-In
relates. The Holder shall provide the Company written notice indicating the
amounts payable to the Holder in respect of the Buy-In.

          (p) The Company will not at any time close its transfer books against
the transfer, as applicable, of this Note or of any shares of Common Stock
issued or issuable upon the conversion of this Note in any manner which
interferes with the timely conversion of this Note, except as may otherwise be
required to comply with applicable securities laws.

          (q) Notwithstanding anything to the contrary contained herein, the
number of Conversion Shares that may be acquired by the Holder upon any
conversion of this Note (or otherwise in respect hereof) shall be limited to the
extent necessary to insure that, following such conversion (or other issuance),
the total number of shares of Common Stock then beneficially owned by such
Holder and its Affiliates and any other Persons whose beneficial ownership of
Common Stock would be aggregated with the Holder's for purposes of Section 13(d)
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), does
not exceed 9.999% of the total number of issued and outstanding shares of Common
Stock (including for such purpose the shares of Common Stock issuable upon such
conversion). For such purposes, beneficial ownership shall be determined in
accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder. This provision shall not restrict the number of shares
of Common Stock which a Holder may receive or beneficially own in order to
determine the amount of securities or other consideration that such Holder may
receive in the event of a transaction contemplated by Section 4(f) of this Note.
This restriction may not be waived.

be presented therein, disclosing the nature thereof.

          (iii) The Company shall promptly notify the Holder of the occurrence
of any Event of Default or any event which, with the giving of notice, the lapse

action (if any) which is proposed to be taken with respect thereto.

          (iv) The Company shall promptly notify the Holder of any action, suit

          (v) The Company shall promptly notify the Holder of any default in the

<PAGE>

property, except those that are being contested in good faith by appropriate

maintain with financially sound and reputable insurance companies insurance
covering its assets and its businesses in such amounts and covering such risks
(including, without limitation, hazard, business interruption and public
liability) as is consistent with sound business practice and as may be obtained
at commercially reasonable rates. The insurance policies will comply with the
provisions of Section 11 of the Security Agreement.

          (ix) The Company shall and shall cause each Subsidiary to comply with
all laws, rules, regulations, orders, writs, judgments, injunctions, decrees or
awards to which they may be subject except where the failure to so comply could
not reasonably be expected to have a Material Adverse Effect.

          (x) The Company shall and shall cause each Subsidiary to use
commercially reasonable efforts to do all things necessary to maintain,
preserve, protect and keep its properties in good repair, working order and
condition and use commercially reasonable efforts to make all necessary and
proper repairs, renewals and replacements so that its business carried on in
connection therewith may be properly conducted.

          (xi) At its own expense, the Company shall and shall cause each
Subsidiary to make, execute, endorse, acknowledge, file and/or deliver any
documents and take all commercially reasonable actions necessary or required to
maintain its ownership rights in its Intellectual Property, including, without
limitation, (i) any action reasonably required to protect the Intellectual
Property in connection with any infringement, suspected infringement, passing
off, act of unfair competition or other unlawful interference with the rights of
the Company or any Subsidiary in and to such Intellectual Property, and (ii) any
registrations with the United States Patent & Trademark Office and any
corresponding foreign patent and/or trademark office required for the Company or
any Subsidiary to carry on its business as presently conducted and as presently
proposed to be conducted. Except for non-exclusive licenses granted in the
ordinary course of business, the Company shall not and shall cause each
Subsidiary not to transfer, assign or otherwise convey the Intellectual
Property, any registrations or applications thereof and all goodwill associated

          (xii) Promptly after the occurrence thereof, the Company shall and
shall cause each Subsidiary to inform the Holder of the following material

other than Permitted Indebtedness, by the Company or any Subsidiary, (iv) a
change in the number of the Board of Directors of the Company, (v) a sale, lease
or transfer of any material portion of the assets of the Company or any

than $4,500,000 (the "Cash Target"); provided, however, that if the Company's
Peridex(R) product line is divested, the Cash Target shall be increased to

          (xiv) The Company shall maintain Pro Forma EBITDA of at least $1 (the

is divested, the EBITDA Target shall be decreased by $1,500,000 on an annualized
basis, commencing on the closing date of such divestiture. For the avoidance of
doubt, if the Peridex(R) divestiture is consummated on December 31, 2007, the

provided, however, that if the Company's Peridex(R) product line is divested,
the Net Income Target shall be decreased by $1,500,000 on an annualized basis,
commencing on the closing date of such divestiture. For the avoidance of doubt,
if the Peridex(R) divestiture is consummated on June 30, 2008, the Net Income
Target for the fiscal quarter ending July 31, 2008 would be -$125,000 and if the
Peridex(R) divestiture is consummated on April 15, 2008, the Net Income Target
for the fiscal quarter ending July 31, 2008 would be -$375,000.

          (xvi) The Company shall have Consolidated Net Income of at least $1
for each fiscal quarter commencing with the fiscal quarter ending October 31,
2008.

          (xvii) Within 45 days after the end of each of the first three fiscal
quarters and within 60 days after the end of each Fiscal Year, the Company shall
deliver to the Holder an officer's certificate, in a form reasonably
satisfactory to the Holder and signed by the Company's Chief Financial Officer,

of Default exists, specifying the nature of such default or Event of Default and
the Company's plans to cure such default or Event of Default and demonstrating
the Company's compliance with each of the financial covenants set forth in
Sections 5(a)(xiii) through 5(a)(xvi), as applicable. Each such officer's

          (b) So long as any amount due under this Note is outstanding and until
the earlier of (i) the indefeasible payment in full of all amounts payable by
the Company hereunder and (ii) the conversion of this Note, without the prior
written consent of the Majority Holders (for purposes of this Section 5(b), any
Company Notes held by any employee, director or officer of the Company or any
Subsidiary shall not be deemed to be outstanding):

          (i) The Company shall not and shall cause each Subsidiary not to
create, incur, guarantee, issue, assume or in any manner become liable in
respect of any Indebtedness, other than Permitted Indebtedness.

create, incur, assume or suffer to exist any Lien upon any of its property,
whether now owned or hereafter acquired other than (i) Liens created pursuant to
the Security Agreement and (ii) Permitted Liens. The Company shall not, and
shall cause each Subsidiary not to, be bound by any agreement which limits the
ability of the Company or any Subsidiary to grant Liens.

          (iii) The Company shall not and shall cause each Subsidiary not to,
directly or indirectly, enter into or permit to exist any transaction or series
of related transactions (including, without limitation, the purchase, sale,

service as an employee)) with, or for the benefit of, any of its Affiliates
other than a wholly owned Subsidiary, except for consulting arrangements with
directors approved by the Board.

          (iv) The Company shall not, and shall cause each of its Subsidiaries
not to, directly or indirectly, declare or pay any dividends on account of any
shares of any class or series of its capital stock now or hereafter outstanding,
or set aside or otherwise deposit or invest any sums for such purpose, or
redeem, retire, defease, purchase or otherwise acquire any shares of any class
of its capital stock (or set aside or otherwise deposit or invest any sums for
such purpose) for any consideration or apply or set apart any sum, or make any
other distribution (by reduction of capital or otherwise) in respect of any such
shares or pay any interest, premium if any, or principal of any Indebtedness or
redeem, retire, defease, repurchase or otherwise acquire any Indebtedness (or
set aside or otherwise deposit or invest any sums for such purpose) for any
consideration or apply or set apart any sum, or make any other payment in
respect thereof or agree to do any of the foregoing (each of the foregoing is
herein called a "Restricted Payment"); provided, that (i) the Company may make
payments of interest, premium if any, and principal of the Notes in accordance
with the terms hereof, (ii) provided that no Event of Default or event which,
with the giving of notice, the lapse of time or both would constitute an Event
of Default has occurred and is continuing, the Company may declare and pay
regular, recurring dividends on the shares of its Series B Preferred Stock
outstanding on the date hereof in accordance with the terms of the Series B
Preferred Stock as in effect on the date hereof, (iii) provided that no Event of
Default or event which, with the giving of notice, the lapse of time or both
would constitute an Event of Default has occurred and is continuing, the Company
and its Subsidiaries may make regularly scheduled payments of interest and
principal of any Permitted Indebtedness, (iv) any Subsidiary directly or
indirectly wholly owned by the Company may pay dividends on its capital stock

permitted under this clause (v) shall not exceed $1,000,000 in the aggregate,
and (C) no such payment may be made if an Event of Default or an event which,
with the giving of notice, the lapse of time or both would constitute an Event
of Default has occurred and is continuing or would result from such payment.

          (v) Except as contemplated by the Permitted Acquisition, the Company
shall not and shall cause each Subsidiary not to, directly or indirectly, engage
in any business other than the business of developing, manufacturing and

          (vii) The Company shall not and shall cause each Subsidiary not to,
directly or indirectly, become or remain liable as lessee or as a guarantor or
other surety with respect to any lease of any property (whether real, personal
or mixed), whether now owned or hereafter acquired, which the Company or any
Subsidiary (a) has sold or transferred or is to sell or to transfer to any other
Person, or (b) intends to use for substantially the same purpose as any other

<PAGE>

amount (which acceleration is not rescinded, annulled or otherwise cured within
ten (10) days of receipt by the Company or a Subsidiary of notice of such
acceleration);

          (e) the Company makes an assignment for the benefit of creditors or
admits in writing its inability to pay its debts generally as they become due;

law; or the Company petitions or applies to any tribunal for the appointment of
a custodian, trustee, receiver or liquidator of the Company or of any
substantial part of the assets of the Company, or commences any proceeding
relating to it under any bankruptcy, reorganization, arrangement, insolvency,

such petition or application is filed, or any such proceeding is commenced,
against the Company and either (i) the Company by any act indicates its approval
thereof, consents thereto or acquiescence therein or (ii) such petition
application or proceeding is not dismissed within sixty (60) days;

          (f) a final, non-appealable judgment which, in the aggregate with
other outstanding final judgments against the Company and its Subsidiaries,
exceeds $250,000 shall be rendered against the Company or a Subsidiary and
within sixty (60) days after entry thereof, such judgment is not discharged or
execution thereof stayed pending appeal, or within sixty (60) days after the
expiration of such stay, such judgment is not discharged; provided, however,
that a judgment that provides for the payment of royalties subsequent to the

judgment;

          (g) the Company is in breach of the requirements of Sections
5(a)(xiii) through 5(a)(xvii) or Section 5(b) hereof;

when made or furnished;

          (i) any Liens created by the Security Documents shall at any time not
constitute a valid and perfected first priority Lien on the collateral intended
to be covered thereby (to the extent perfection by filing, registration,
recordation or possession is required herein or therein) in favor of the
Holders, free and clear of all other Liens (other than Permitted Liens), or any
of the security interests granted pursuant to the Security Documents shall be
determined to be void, voidable, invalid or unperfected, are subordinated or are
ineffective to provide the Holder with a perfected, first priority security
interest in the collateral covered by the Security Documents, free and clear of
all other Liens (other than Permitted Liens) or, except for expiration or
termination in accordance with their terms, the Security Agreement shall for
whatever reason be terminated or cease to be in full force and effect, or the
enforceability thereof or any other Transaction Documents shall be contested by
the Company;

          (j) if the Company fails to observe or perform in any material respect
any of its covenants contained in the Transaction Documents (other than any
failure covered by Section

                                      A-23

<PAGE>

6(a), (b) or (g)), and such failure continues for thirty (30) days after receipt
by the Company of notice thereof;

          (k) the Proposal Date does not occur on or prior to December 31, 2006;
or

          (l) The Company shall fail to comply with the corporate governance
changes as specified in the writing delivered to the Holder pursuant to the
terms of the Purchase Agreement on or prior to the respective dates set forth in
such writing.

     Upon the occurrence of any such Event of Default, except as provided in the
following paragraph, all unpaid principal and accrued interest under this Note
shall become immediately due and payable (A) upon election of the Holder, with
respect to (a) through (d) and (f) through (l), and (B) automatically, with
respect to (e). Except as provided in the following paragraph, upon the
occurrence of any Event of Default, the Holder may, in addition to declaring all
amounts due hereunder to be immediately due and payable, pursue any available
remedy, whether at law or in equity, including, without limitation, exercising
its rights under the other Transaction Documents. If an Event of Default occurs,
the Company shall pay to the Holder the reasonable attorneys' fees and
disbursements and all other reasonable out-of-pocket costs incurred by the
Holder in order to collect amounts due and owing under this Note or otherwise to
enforce the Holder's rights and remedies hereunder and under the other
Transaction Documents.

     So long as the only Events of Default that have occurred and are continuing
are Qualifying Events of Default, upon the first occurrence of a Qualifying
Event of Default which is not cured by the Company or waived or rescinded by the
Holder, the Holder's right to accelerate the principal and interest due under
this Note shall be limited to one-third of the outstanding principal amount and
all accrued interest then due under this Note (the "First Default Amount"). The
date on which notice of the acceleration of the First Default Amount is given by
the Holder is hereinafter referred to as the "First Acceleration Date." Upon the
second occurrence of a Qualifying Event of Default which is not cured or waived
or rescinded by the Holder or upon the continuation of an existing Qualifying
Event of Default more than 90 days after the First Acceleration Date and
provided that the Holder shall have received the indefeasible payment in full of
the First Default Amount, the Holder's right to accelerate the principal and
interest due under this Note shall be limited to one-half of the outstanding
principal amount and all accrued interest then due under this Note (the "Second
Default Amount"); provided, however, that no such acceleration shall be
effective until 90 days after the First Acceleration Date. The date on which
notice of the acceleration of the Second Default Amount is given by the Holder
is hereinafter referred to as the "Second Acceleration Date." Upon the third
occurrence of a Qualifying Event of Default which is not cured by the Company or
waived or rescinded by the Holder or upon the continuation of an existing
Qualifying Event of Default more than 90 days after the Second Acceleration Date
and provided that the Holder shall have received the indefeasible payment in
full of the First Default Amount and the Second Default Amount, the Holder shall
not have the right to accelerate the remaining outstanding principal amount and
all accrued interest then due under this Note until 90 days after the Second
Acceleration Date. The failure of the Company to indefeasibly pay in full the
First Default Amount or the Second Default Amount within three days of the First
Acceleration Date or the Second Acceleration Date, as applicable, shall
constitute an additional Event of Default hereunder and shall entitle the
Holder, at its option, to declare the entire principal amount of this Note and
all accrued interest

                                      A-24

<PAGE>

hereunder immediately due and payable. In no event shall the Holder proceed
against the collateral pursuant to the terms of the Security Agreement in
respect of one or more Qualifying Events of Default subject to the provisions of
this paragraph unless and until the Company shall have failed to pay the First
Default Amount or the Second Default Amount, as applicable, within three days of
the First Acceleration Date or the Second Acceleration Date, as applicable.

     7. No Waiver. To the extent permitted by applicable law, no delay or
omission on the part of the Holder in exercising any right under this Note shall
operate as a waiver of such right or of any other right of the Holder, nor shall
any delay, omission or waiver on any one occasion be deemed a bar to or waiver
of the same or any other right on any future occasion.

     8. Amendments in Writing. Any term of this Note may be amended or waived
upon the written consent of the Company and the holders of Company Notes
representing at least 50% of the principal amount of Company Notes then
outstanding (the "Majority Holders"); provided, that (x) any such amendment or
waiver must apply to all outstanding Company Notes; and (y) without the consent
of the Holder hereof, no amendment or waiver shall (i) change the Stated
Maturity Date of this Note, (ii) reduce the principal amount of this Note or the
interest rate due hereon, (iii) change the Conversion Price or (iv) change the
place of payment of this Note. No such waiver or consent on any one instance
shall be construed to be a continuing waiver or a waiver in any other instance
unless it expressly so provides.

     9. Waivers. The Company hereby forever waives presentment, demand,
presentment for payment, protest, notice of protest, notice of dishonor of this
Note and all other demands and notices in connection with the delivery,
acceptance, performance and enforcement of this Note.

     10. Waiver of Jury Trial. THE COMPANY HEREBY WAIVES ITS RIGHT TO A JURY
TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS NOTE OR
ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL
OTHER CLAIMS. THE COMPANY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

     11. Secured Obligation. This Note is one of the Notes referred to in the
Security Agreement and is secured by the collateral described therein. The
Security Agreement grants the Holder certain rights with respect to such
collateral upon an Event of Default.

     12. Governing Law; Consent to Jurisdiction. This Note shall be governed by
and construed under the law of the State of New York, without giving effect to
the conflicts of law principles thereof. The Company and, by accepting this
Note, the Holder, each irrevocably submits to the exclusive jurisdiction of the
courts of the State of New York located in New York County and the United States
District Court for the Southern District of New York for the purpose of any
suit, action, proceeding or judgment relating to or arising out of this Note and
the transactions contemplated hereby. Service of process in connection with any
such suit, action or proceeding may be served on each party hereto anywhere in
the world by the same methods as are specified for the giving of notices under
this Note. The Company and, by accepting this Note, the Holder, each irrevocably
consents to the jurisdiction of any such court in any such suit, action or
proceeding and to the laying of venue in such court. The Company and, by
accepting

                                      A-25

<PAGE>

this Note, the Holder, each irrevocably waives any objection to the laying of
venue of any such suit, action or proceeding brought in such courts and
irrevocably waives any claim that any such suit, action or proceeding brought in
any such court has been brought in an inconvenient forum.

     13. Costs. If action is instituted to collect on this Note, the Company
promises to pay all reasonable costs and expenses, including reasonable
attorney's fees, incurred in connection with such action.

     14. Notices. All notices hereunder shall be given in writing and shall be
deemed delivered when received by the other party hereto at the address set
forth in the Purchase Agreement or at such other address as may be specified by
such party from time to time in accordance with the Purchase Agreement.

     15. Successors and Assigns. This Note shall be binding upon the successors
or assigns of the Company and shall inure to the benefit of the successors and
assigns of the Holder.

$2.21 (the exercise price in effect being herein called the "Warrant Price"),
______ shares ("Warrant Shares") of the Company's Common Stock, par value $0.001
per share ("Common Stock"). The number of Warrant Shares purchasable upon
exercise of this Warrant and the Warrant Price shall be subject to adjustment

     Section 2. Transfers. As provided herein, this Warrant may be transferred

exercise (or the date evidence of loss, theft or destruction thereof and
security or indemnity satisfactory to the Company has been provided to the
Company in connection with such exercise), the Warrant Price

<PAGE>

shall have been paid and the completed Exercise Agreement shall have been
delivered. Certificates for the Warrant Shares so purchased shall be delivered
to the Warrantholder within a reasonable time, not exceeding three (3) business
days, after this Warrant shall have been so exercised. The certificates so
delivered shall be in such denominations as may be requested by the
Warrantholder and shall be registered in the name of the Warrantholder or such
other name as shall be designated by the Warrantholder, as specified in the
Exercise Agreement. If this Warrant shall have been exercised only in part,
then, unless this Warrant has expired, the Company shall, at its expense, at the
time of delivery of such certificates, deliver to the Warrantholder a new
Warrant representing the right to purchase the number of shares with respect to
which this Warrant shall not then have been exercised. As used herein, "business
day" means a day, other than a Saturday or Sunday, on which banks in New York
City are open for the general transaction of business. Each exercise hereof
shall constitute the re-affirmation by the Warrantholder that the
representations and warranties contained in Section 5 of the Purchase Agreement
are true and correct in all material respects with respect to the Warrantholder
as of the time of such exercise.

     Section 4. Compliance with the Securities Act of 1933. Except as provided
in the Purchase Agreement, the Company may cause the legend set forth on the
first page of this Warrant to be set forth on each Warrant, and a similar legend
on any security issued or issuable upon exercise of this Warrant, unless counsel
for the Company is of the opinion as to any such security that such legend is
unnecessary.

     Section 5. Payment of Taxes. The Company will pay any documentary stamp
taxes attributable to the initial issuance of Warrant Shares issuable upon the
exercise of the Warrant; provided, however, that the Company shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issuance or delivery of any certificates for Warrant Shares in a
name other than that of the Warrantholder in respect of which such shares are
issued, and in such case, the Company shall not be required to issue or deliver
any certificate for Warrant Shares or any Warrant until the person requesting
the same has paid to the Company the amount of such tax or has established to
the Company's reasonable satisfaction that such tax has been paid. The
Warrantholder shall be responsible for income taxes due under federal, state or
other law, if any such tax is due.

     Section 6. Mutilated or Missing Warrants. In case this Warrant shall be
mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and
substitution of and upon surrender and cancellation of the mutilated Warrant, or
in lieu of and substitution for the Warrant lost, stolen or destroyed, a new
Warrant of like tenor and for the purchase of a like number of Warrant Shares,
but only upon receipt of evidence reasonably satisfactory to the Company of such
loss, theft or destruction of the Warrant, and with respect to a lost, stolen or
destroyed Warrant, reasonable indemnity with respect thereto, if requested by
the Company.

     Section 7. Reservation of Common Stock. The Company hereby represents and
warrants that there have been reserved, and the Company shall at all applicable
times keep reserved until issued (if necessary) as contemplated by this Section
7, out of the authorized and unissued shares of Common Stock, sufficient shares
to provide for the exercise of the rights of purchase represented by this
Warrant. The Company agrees that all Warrant Shares issued upon due exercise of
the Warrant shall be, at the time of delivery of the certificates for such
Warrant Shares, duly authorized, validly issued, fully paid and non-assessable
shares of Common Stock of the Company.

     Section 8. Adjustments. Subject and pursuant to the provisions of this
Section 8, the Warrant Price and number of Warrant Shares subject to this
Warrant shall be subject to adjustment from time to time as set forth
hereinafter.

          (a) If the Company shall, at any time or from time to time while this
Warrant is outstanding, pay a dividend or make a distribution on its Common
Stock in shares of Common Stock, subdivide its outstanding shares of Common
Stock into a greater number of shares or combine its outstanding shares of
Common Stock into a smaller number of shares or issue by reclassification of its
outstanding shares of Common Stock any shares of its capital stock (including
any such reclassification in connection with a consolidation or merger in which
the Company is the continuing corporation), then (i) the Warrant Price in effect
immediately prior to the date on which such change shall become effective shall
be adjusted by multiplying such Warrant Price by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such change and the denominator of which shall be the number of shares
of Common Stock outstanding immediately after giving effect to such change and
(ii) the number of Warrant Shares purchasable upon exercise of this Warrant
shall be adjusted by multiplying the number of Warrant Shares purchasable upon
exercise of this Warrant immediately prior to the date

                                       B-2

<PAGE>

on which such change shall become effective by a fraction, the numerator of
which is shall be the Warrant Price in effect immediately prior to the date on
which such change shall become effective and the denominator of which shall be
the Warrant Price in effect immediately after giving effect to such change,
calculated in accordance with clause (i) above. Such adjustments shall be made
successively whenever any event listed above shall occur.

          (b) If any capital reorganization, reclassification of the capital
stock of the Company, consolidation or merger of the Company with another
corporation in which the Company is not the survivor, or sale, transfer or other
disposition of all or substantially all of the Company's assets to another
corporation shall be effected, then, as a condition of such reorganization,
reclassification, consolidation, merger, sale, transfer or other disposition,
lawful and adequate provision shall be made whereby each Warrantholder shall
thereafter have the right to purchase and receive upon the basis and upon the
terms and conditions herein specified and in lieu of the Warrant Shares
immediately theretofore issuable upon exercise of the Warrant, such shares of
stock, securities or assets as would have been issuable or payable with respect
to or in exchange for a number of Warrant Shares equal to the number of Warrant
Shares immediately theretofore issuable upon exercise of the Warrant, had such
reorganization, reclassification, consolidation, merger, sale, transfer or other
disposition not taken place, and in any such case appropriate provision shall be
made with respect to the rights and interests of each Warrantholder to the end
that the provisions hereof (including, without limitation, provision for
adjustment of the Warrant Price) shall thereafter be applicable, as nearly
equivalent as may be practicable in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise hereof. The Company shall not
effect any such consolidation, merger, sale, transfer or other disposition
unless prior to or simultaneously with the consummation thereof the successor
corporation (if other than the Company) resulting from such consolidation or
merger, or the corporation purchasing or otherwise acquiring such assets or
other appropriate corporation or entity shall assume the obligation to deliver
to the Warrantholder, at the last address of the Warrantholder appearing on the
books of the Company, such shares of stock, securities or assets as, in
accordance with the foregoing provisions, the Warrantholder may be entitled to
purchase, and the other obligations under this Warrant. The provisions of this
paragraph (b) shall similarly apply to successive reorganizations,
reclassifications, consolidations, mergers, sales, transfers or other
dispositions.

          (c) In case the Company shall fix a payment date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness or assets (other than cash
dividends or cash distributions payable out of consolidated earnings or earned
surplus or dividends or distributions referred to in Section 8(a)), or
subscription rights or warrants, the Warrant Price to be in effect after such
payment date shall be determined by multiplying the Warrant Price in effect
immediately prior to such payment date by a fraction, the numerator of which
shall be the total number of shares of Common Stock outstanding multiplied by
the Market Price (as defined below) per share of Common Stock immediately prior
to such payment date, less the fair market value (as determined by the Company's
Board of Directors in good faith) of said assets or evidences of indebtedness so
distributed, or of such subscription rights or warrants, and the denominator of
which shall be the total number of shares of Common Stock outstanding multiplied
by such Market Price per share of Common Stock immediately prior to such payment
date. "Market Price", as of a particular date (the "Valuation Date"), shall mean
the following: (a) if the Common Stock is then listed on a national stock
exchange, the closing sale price of one share of Common Stock on such exchange
on the last Trading Day prior to the Valuation Date; (b) if the Common Stock is
then quoted on the National Association of Securities Dealers, Inc. OTC Bulletin
Board (the "Bulletin Board") or such similar quotation system or association,
the closing sale price of one share of Common Stock on the Bulletin Board or
such other quotation system or association on the last Trading Day prior to the
Valuation Date or, if no such closing sale price is available, the average of
the high bid and the low asked price quoted thereon on the last trading day
prior to the Valuation Date; (c) if such security is then included in the "pink
sheets," the closing sale price of one share of Common Stock on the "pink
sheets" on the last Trading Day prior to the Valuation Date or, if no such
closing sale price is available, the average of the high bid and the low ask
price quoted on the "pink sheets" as of the end of the last Trading Day prior to
the Valuation Date; or (d) if the Common Stock is not then listed on a national
stock exchange or quoted on the Bulletin Board, the "pink sheets" or such other
quotation system or association, the fair market value of one share of Common
Stock as of the Valuation Date, as determined in good faith by the Board of
Directors of the Company and the Warrantholder. If the Common Stock is not then
listed on a national securities exchange or quoted on the Bulletin Board, the
"pink sheets" or other quotation system or association, the Board of Directors
of the Company shall respond promptly, in writing, to an inquiry by the
Warrantholder prior to the exercise hereunder as to the fair market value of a
share of Common Stock as determined by the Board of Directors of the Company. In
the event that the Board of Directors of the Company and the Warrantholder are
unable to agree

                                       B-3

<PAGE>

upon the fair market value in respect of subpart (d) of this paragraph, the
Company and the Warrantholder shall jointly select an appraiser, who is
experienced in such matters. The decision of such appraiser shall be final and
conclusive, and the cost of such appraiser shall be borne equally by the Company
and the Warrantholder. Such adjustment shall be made successively whenever such
a payment date is fixed.

          (d) An adjustment to the Warrant Price shall become effective
immediately after the payment date in the case of each dividend or distribution
and immediately after the effective date of each other event which requires an
adjustment.

          (e) In the event that, as a result of an adjustment made pursuant to
this Section 8, the Warrantholder shall become entitled to receive any shares of
capital stock of the Company other than shares of Common Stock, the number of
such other shares so receivable upon exercise of this Warrant shall be subject
thereafter to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to the Warrant Shares
contained in this Warrant.

          (f) Except as provided in subsection (g) hereof, if and whenever the
Company shall issue or sell, or is, in accordance with any of subsections (f)(l)
through (f)(7) hereof, deemed to have issued or sold, any Additional Shares of
Common Stock (as defined below) for no consideration or for a consideration per
share less than the Warrant Price in effect immediately prior to the time of
such issuance or sale, then and in each such case (a "Trigger Issuance") the
then-existing Warrant Price, shall be reduced, as of the close of business on
the effective date of the Trigger Issuance, to a price determined as follows:

          Adjusted Warrant Price = (A x B) + D
                                   -----------
                                       A+C

                    where

                    "A" equals the number of shares of Common Stock outstanding,
including Additional Shares of Common Stock (as defined below) deemed to be
issued hereunder, immediately preceding such Trigger Issuance;

                    "B" equals the Warrant Price in effect immediately preceding
such Trigger Issuance;

                    "C" equals the number of Additional Shares of Common Stock
issued or deemed issued hereunder as a result of the Trigger Issuance; and

                    "D" equals the aggregate consideration, if any, received or
deemed to be received by the Company upon such Trigger Issuance;

provided, however, that in no event shall the Warrant Price after giving effect
to such Trigger Issuance be greater than the Warrant Price in effect prior to
such Trigger Issuance.

     For purposes of this subsection (f), "Additional Shares of Common Stock"
shall mean all shares of Common Stock issued or sold by the Company or deemed to
be issued or sold pursuant to this subsection (f), other than Excluded Issuances
(as defined in subsection (g) hereof).

     For purposes of this subsection (f), the following subsections (f)(l) to
(f)(8) shall also be applicable (subject, in each such case, to the provisions
of Section 8(g) hereof):

               (f)(1) Issuance of Rights or Options. In case at any time the
Company shall in any manner grant (directly and not by assumption in a merger or
otherwise) any warrants or other rights to subscribe for or to purchase, or any
options for the purchase of, Common Stock or any stock or security convertible
into or exchangeable for Common Stock (such warrants, rights or options being
called "Options" and such convertible or exchangeable stock or securities being
called "Convertible Securities") whether or not such Options or the right to

                                      B-4

<PAGE>

convert or exchange any such Convertible Securities are immediately exercisable,
and the price per share for which Common Stock is issuable upon the exercise of
such Options or upon the conversion or exchange of such Convertible Securities
(determined by dividing (i) the sum (which sum shall constitute the applicable
consideration) of (x) the total amount, if any, received or receivable by the
Company as consideration for the granting of such Options, plus (y) the
aggregate amount of additional consideration payable to the Company upon the
exercise of all such Options, plus (z), in the case of such Options which relate
to Convertible Securities, the aggregate amount of additional consideration, if
any, payable upon the issuance or sale of such Convertible Securities and upon
the conversion or exchange thereof, by (ii) the total maximum number of shares
of Common Stock issuable upon the exercise of such Options or upon the
conversion or exchange of all such Convertible Securities issuable upon the
exercise of such Options) shall be less than the Warrant Price in effect
immediately prior to the time of the granting of such Options, then the total
number of shares of Common Stock issuable upon the exercise of such Options or
upon conversion or exchange of the total amount of such Convertible Securities
issuable upon the exercise of such Options shall be deemed to have been issued
for such price per share as of the date of granting of such Options or the
issuance of such Convertible Securities and thereafter shall be deemed to be
outstanding for purposes of adjusting the Warrant Price. Except as otherwise
provided in subsection 8(f)(3), no adjustment of the Warrant Price shall be made
upon the actual issuance of such Common Stock or of such Convertible Securities
upon exercise of such Options or upon the actual issuance of such Common Stock
upon conversion or exchange of such Convertible Securities.

               (f)(2) Issuance of Convertible Securities. In case the Company
shall in any manner issue (directly and not by assumption in a merger or
otherwise) or sell any Convertible Securities, whether or not the rights to
exchange or convert any such Convertible Securities are immediately exercisable,
and the price per share for which Common Stock is issuable upon such conversion
or exchange (determined by dividing (i) the sum (which sum shall constitute the
applicable consideration) of (x) the total amount received or receivable by the
Company as consideration for the issuance or sale of such Convertible
Securities, plus (y) the aggregate amount of additional consideration, if any,
payable to the Company upon the conversion or exchange thereof, by (ii) the
total number of shares of Common Stock issuable upon the conversion or exchange
of all such Convertible Securities) shall be less than the Warrant Price in
effect immediately prior to the time of such issuance or sale, then the total
maximum number of shares of Common Stock issuable upon conversion or exchange of
all such Convertible Securities shall be deemed to have been issued for such
price per share as of the date of the issuance or sale of such Convertible
Securities and thereafter shall be deemed to be outstanding for purposes of
adjusting the Warrant Price, provided that (a) except as otherwise provided in
subsection 8(f)(3), no adjustment of the Warrant Price shall be made upon the
actual issuance of such Common Stock upon conversion or exchange of such
Convertible Securities and (b) no further adjustment of the Warrant Price shall
be made by reason of the issuance or sale of Convertible Securities upon
exercise of any Options to purchase any such Convertible Securities for which
adjustments of the Warrant Price have been made pursuant to the other provisions
of subsection 8(f).

               (f)(3) Change in Option Price or Conversion Rate. Upon the
happening of any of the following events, namely, if the purchase price provided
for in any Option referred to in subsection 8(f)(l) hereof, the additional
consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in subsections 8(f)(l) or 8(f)(2), or the
rate at which Convertible Securities referred to in subsections 8(f)(l) or
8(f)(2) are convertible into or exchangeable for Common Stock shall change at
any time (including, but not limited to, changes under or by reason of
provisions designed to protect against dilution), the Warrant Price in effect at
the time of such event shall forthwith be readjusted to the Warrant Price which
would have been in effect at such time had such Options or Convertible
Securities still outstanding provided for such changed purchase price,
additional consideration or conversion rate, as the case may be, at the time
initially granted, issued or sold. On the termination of any Option for which
any adjustment was made pursuant to this subsection 8(f) or any right to convert
or exchange Convertible Securities for which any adjustment was made pursuant to
this subsection 8(f) (including without limitation upon the redemption or
purchase for consideration of such Convertible Securities by the Company), the
Warrant Price then in effect hereunder shall forthwith be changed to the Warrant
Price which would have been in effect at the time of such termination had such
Option or Convertible Securities, to the extent outstanding immediately prior to
such termination, never been issued.

               (f)(4) Stock Dividends. Subject to the provisions of this Section
8(f), in case the Company shall declare a dividend or make any other
distribution upon any stock of the Company (other than the Common Stock) payable
in Common Stock, Options or Convertible Securities, then any Common Stock,
Options or

                                      B-5

<PAGE>

Convertible Securities, as the case may be, issuable in payment of such dividend
or distribution shall be deemed to have been issued or sold without
consideration; provided, that if any adjustment is made to the Warrant Price as
a result of a declaration of a dividend and such dividend is rescinded, the
Warrant Price shall be appropriately readjusted to the Warrant Price in effect
had such dividend not been declared.

               (f)(5) Consideration for Stock. In case any shares of Common
Stock, Options or Convertible Securities shall be issued or sold for cash, the
consideration received therefor shall be deemed to be the net amount received by
the Company therefor, after deduction therefrom of any expenses incurred or any
underwriting commissions or concessions paid or allowed by the Company in
connection therewith. In case any shares of Common Stock, Options or Convertible
Securities shall be issued or sold for a consideration other than cash, the
amount of the consideration other than cash received by the Company shall be
deemed to be the fair value of such consideration as determined in good faith by
the Board of Directors of the Company, after deduction of any expenses incurred
or any underwriting commissions or concessions paid or allowed by the Company in
connection therewith. In case any Options shall be issued in connection with the
issuance and sale of other securities of the Company, together comprising one
integral transaction in which no specific consideration is allocated to such
Options by the parties thereto, such Options shall be deemed to have been issued
for such consideration as determined in good faith by the Board of Directors of
the Company. If Common Stock, Options or Convertible Securities shall be issued
or sold by the Company and, in connection therewith, other Options or
Convertible Securities (the "Additional Rights") are issued, then the
consideration received or deemed to be received by the Company shall be reduced
by the fair market value of the Additional Rights (as determined using the
Black-Scholes option pricing model or another method mutually agreed to by the
Company and the Warrantholder). The Board of Directors of the Company shall
respond promptly, in writing, to an inquiry by the Warrantholder as to the fair
market value of the Additional Rights. In the event that the Board of Directors
of the Company and the Warrantholder are unable to agree upon the fair market
value of the Additional Rights, the Company and the Warrantholder shall jointly
select an appraiser, who is experienced in such matters. The decision of such
appraiser shall be final and conclusive, and the cost of such appraiser shall be
borne evenly by the Company and the Warrantholder.

               (f)(6) Record Date. In case the Company shall take a record of
the holders of its Common Stock for the purpose of entitling them (i) to receive
a dividend or other distribution payable in Common Stock, Options or Convertible
Securities or (ii) to subscribe for or purchase Common Stock, Options or
Convertible Securities, then such record date shall be deemed to be the date of
the issuance or sale of the shares of Common Stock deemed to have been issued or
sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

               (f)(7) Treasury Shares. The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of the Company or any of its wholly-owned subsidiaries, and the
disposition of any such shares (other than the cancellation or retirement
thereof) shall be considered an issuance or sale of Common Stock for the purpose
of this subsection (f).

               (f)(8) Nasdaq Limitation. Notwithstanding any other provision in
Section 8(f) to the contrary, if a reduction in the Warrant Price pursuant to
Section 8(f) (other than as set forth in this clause (f)(8)) would require the
Company to obtain stockholder approval of the transactions contemplated by the
Purchase Agreement to be consummated on the Closing Date pursuant to Nasdaq
Marketplace Rule 4350(i) and such stockholder approval has not been obtained,
(i) the Warrant Price shall be reduced to the maximum extent that would not
require stockholder approval under such Rule, and (ii) the Company shall use its
commercially reasonable efforts to obtain such stockholder approval as soon as
reasonably practicable, including by calling a special meeting of stockholders
to vote on such Warrant Price adjustment. This provision shall not restrict the
number of shares of Common Stock which a Warrantholder may receive or
beneficially own in order to determine the amount of securities or other
consideration that such Holder may receive in the event of a transaction
contemplated by Section 8 of this Warrant.

          (g) Anything herein to the contrary notwithstanding, the Company shall
not be required to make any adjustment of the Warrant Price in the case of the
issuance of (A) capital stock, Options or Convertible Securities issued to
directors, officers, employees or consultants of the Company in connection with
their service as directors of the Company, their employment by the Company or
their retention as consultants by the Company

                                      B-6

<PAGE>

pursuant to an equity compensation program approved by the Board of Directors of
the Company or the compensation committee of the Board of Directors of the
Company, (B) shares of Common Stock issued upon the conversion or exercise of
Options or Convertible Securities issued prior to the date hereof, provided such
securities are not amended after the date hereof to increase the number of
shares of Common Stock issuable thereunder or to lower the exercise or
conversion price thereof, (C) securities issued pursuant to the Purchase
Agreement and securities issued upon the exercise or conversion of those
securities, (D) shares of Common Stock issued or issuable by reason of a
dividend, stock split or other distribution on shares of Common Stock (but only
to the extent that such a dividend, split or distribution results in an
adjustment in the Warrant Price pursuant to the other provisions of this
Warrant) and (E) securities issued pursuant to the Purchase Agreement, dated as
of November __, 2006, and as that agreement may be amended from time to time, by
and among the Company and the certain investors thereto, relating to the sale
and issuance of 9,100,000 shares of Company's Common Stock, warrants to purchase
8,508,000 shares of the Company's Common Stock and the issuance of $12,075,000
in aggregate principal amount of the Company's 12% Convertible Notes due May
2007 (collectively, "Excluded Issuances").

          (h) Upon any adjustment to the Warrant Price pursuant to Section 8(f)
above, the number of Warrant Shares purchasable hereunder shall be adjusted by
multiplying such number by a fraction, the numerator of which shall be the
Warrant Price in effect immediately prior to such adjustment and the denominator
of which shall be the Warrant Price in effect immediately thereafter.

          (i) To the extent permitted by applicable law and the listing
requirements of any stock market or exchange on which the Common Stock is then
listed, the Company from time to time may decrease the Warrant Price by any
amount for any period of time if the period is at least twenty (20) days, the
decrease is irrevocable during the period and the Board shall have made a
determination that such decrease would be in the best interests of the Company,
which determination shall be conclusive. Whenever the Warrant Price is decreased
pursuant to the preceding sentence, the Company shall provide written notice
thereof to the Warrantholder at least five (5) days prior to the date the
decreased Warrant Price takes effect, and such notice shall state the decreased
Warrant Price and the period during which it will be in effect.

     Section 9. Fractional Interest. The Company shall not be required to issue
fractions of Warrant Shares upon the exercise of this Warrant. If any fractional
share of Common Stock would, except for the provisions of the first sentence of
this Section 9, be deliverable upon such exercise, the Company, in lieu of
delivering such fractional share, shall pay to the exercising Warrantholder an
amount in cash equal to the Market Price of such fractional share of Common
Stock on the date of exercise.

     Section 10. Extension of Expiration Date. If the Company fails to cause any
Registration Statement covering Registrable Securities (unless otherwise defined
herein, capitalized terms are as defined in the Registration Rights Agreement
relating to the Warrant Shares (the "Registration Rights Agreement")) to be
declared effective prior to the applicable dates set forth therein, or if any of
the events specified in Section 2(c)(ii) of the Registration Rights Agreement
occurs, and the Blackout Period (whether alone, or in combination with any other
Blackout Period) continues for more than 60 days in any 12 month period, or for
more than a total of 90 days, then the Expiration Date of this Warrant shall be
extended one day for each day beyond the 60-day or 90-day limits, as the case
may be, that the Blackout Period continues.

     Section 11. Benefits. Nothing in this Warrant shall be construed to give
any person, firm or corporation (other than the Company and the Warrantholder)
any legal or equitable right, remedy or claim, it being agreed that this Warrant
shall be for the sole and exclusive benefit of the Company and the
Warrantholder.

     Section 12. Notices to Warrantholder. Upon the happening of any event
requiring an adjustment of the Warrant Price, the Company shall promptly give
written notice thereof to the Warrantholder at the address appearing in the
records of the Company, stating the adjusted Warrant Price and the adjusted
number of Warrant Shares resulting from such event and setting forth in
reasonable detail the method of calculation and the facts upon which such
calculation is based. Failure to give such notice to the Warrantholder or any
defect therein shall not affect the legality or validity of the subject
adjustment.

     Section 13. Identity of Transfer Agent. The Transfer Agent for the Common
Stock is Computershare Trust Company. Upon the appointment of any subsequent
transfer agent for the Common Stock or other shares of

                                      B-7

<PAGE>

the Company's capital stock issuable upon the exercise of the rights of purchase
represented by the Warrant, the Company will mail to the Warrantholder a
statement setting forth the name and address of such transfer agent.

     Section 14. Notices. Unless otherwise provided, any notice required or
permitted under this Warrant shall be given in writing and shall be deemed
effectively given as hereinafter described (i) if given by personal delivery,
then such notice shall be deemed given upon such delivery, (ii) if given by
telex or facsimile, then such notice shall be deemed given upon receipt of
confirmation of complete transmittal, (iii) if given by mail, then such notice
shall be deemed given upon the earlier of (A) receipt of such notice by the
recipient or (B) three days after such notice is deposited in first class mail,
postage prepaid, and (iv) if given by an internationally recognized overnight
air courier, then such notice shall be deemed given one business day after
delivery to such carrier. All notices shall be addressed as follows: if to the
Warrantholder, at its address as set forth in the Company's books and records
and, if to the Company, at the address as follows, or at such other address as
the Warrantholder or the Company may designate by ten days' advance written
notice to the other:

Registration Rights Agreement) which has not been suspended and for which no
stop order is in effect, and pursuant to which the Warrantholder is able to sell

contained herein to the contrary, from and after the first anniversary of the
Closing Date (as defined in the Purchase Agreement) and so long as the Company
is required under the Registration Rights Agreement to have effected the
registration of the Warrant Shares for resale to the public pursuant to a
Registration Statement (as such term is defined in the Registration Rights
Agreement), if the Warrant Shares may not be freely sold to the public as a
result of the Company's failure to perform or satisfy its obligations under the
Registration Rights Agreement, the Warrantholder may elect to receive, without
the payment by the Warrantholder of the aggregate Warrant Price in respect of
the shares of Common Stock to be acquired, shares of Common Stock of equal value
to the value of this Warrant, or any specified portion hereof, by the surrender
of this Warrant (or such portion of this Warrant being so exercised) together
with a Net Issue Election Notice, in the form annexed hereto as Appendix B, duly
executed, to the Company. Thereupon, the Company shall issue to the
Warrantholder such number of fully paid, validly issued and nonassessable shares
of Common Stock as is computed using the following formula:

                                  X = Y (A - B)
                                      ---------
                                          A

where

               X = the number of shares of Common Stock to which the
Warrantholder is entitled upon such cashless exercise;

               Y = the total number of shares of Common Stock covered by this
Warrant for which the Warrantholder has surrendered purchase rights at such time
for cashless exercise (including both shares to be issued to the Warrantholder
and shares as to which the purchase rights are to be canceled as payment
therefor);

               B = the Warrant Price in effect under this Warrant at the time
the net issue election is made.

     Section 20. Limitations on Exercise. Notwithstanding anything to the
contrary contained herein, the number of Warrant Shares that may be acquired by
the Warrantholder upon any exercise of this Warrant (or otherwise in respect
hereof) shall be limited to the extent necessary to insure that, following such
exercise (or other issuance), the total number of shares of Common Stock then
beneficially owned by such Warrantholder and its Affiliates and any other
Persons whose beneficial ownership of Common Stock would be aggregated with the
Warrantholder's for purposes of Section 13(d) of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), does not exceed 9.999% of the total
number of issued and outstanding shares of Common Stock (including for such
purpose the shares of Common Stock issuable upon such exercise). For such
purposes, beneficial ownership shall be determined in accordance with Section
13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
This provision shall not restrict the number of shares of Common Stock which a
Holder may receive or beneficially own in order to determine the amount of
securities or other consideration that such Holder may receive in the event of a
transaction contemplated by Section 8 of this Warrant. This restriction may not
be waived.

Warrant, the Warrantholder shall not have or exercise any rights as a
stockholder of the Company by virtue of its ownership of this Warrant.

of like tenor issued by the Company pursuant to the Purchase Agreement and
initially covering an aggregate of 1,909,091 shares of Common Stock

or waived (including the adjustment provisions included in Section 8 of this
Warrant) upon the written consent of the Company and the holders of Company
Warrants representing at least 50% of the number of shares of Common Stock then
subject to all outstanding Company Warrants (the "Majority Holders"); provided,

modify, amend, limit or restrict the provisions hereof.

as is then available to effect a registration for resale of the Additional

amendment or supplement thereto, and each request for acceleration of
effectiveness thereof) shall be provided in accordance with Section 3(c) to the
Investors and/or their counsel prior to its filing or other submission. If a
Registration Statement covering the Additional Shares is required to be filed
under this Section 2(a)(ii) and is not filed with the SEC within thirty (30)
days of the request of any Investor or upon the occurrence of any of the events
specified in this Section 2(a)(ii), the Company will make pro rata payments to
each Investor, as liquidated damages and not as a penalty, in an amount equal to
1.0% of the aggregate amount invested by such Investor with respect to the
securities giving rise to the issuance of such Additional Shares for each 30-day
period or pro rata for any portion thereof following the date by which such
Registration Statement should have been filed for which no Registration
Statement is filed with respect to the Additional Shares. Such payments shall
constitute the Investors' exclusive monetary remedy for such events, but shall
not affect the right of the Investors to seek injunctive relief. Such payments
shall be made to each Investor in cash.

          (b) Expenses. The Company will pay all expenses associated with each
registration, including filing and printing fees, the Company's counsel and
accounting fees and expenses, costs associated with clearing the Registrable
Securities for sale under applicable state securities laws, listing fees, fees

to Section 2(a)(ii) (the 120th day after such date if the Registration Statement
is reviewed by the SEC), or (B) after a Registration Statement has been declared
effective by the SEC, sales cannot be made pursuant to such Registration
Statement for any reason (including without limitation by reason of a stop
order, or the Company's failure to update the Registration Statement), but

covered thereby due to market conditions and except as excused pursuant to
subparagraph (ii) below, then the Company will make pro rata payments to each
Investor, as liquidated damages and not as a penalty, in an amount equal to (i)
1.0% of the aggregate amount invested by such Investor for the Registrable
Securities included in the applicable Registration Statement that has not been
declared effective (or, in the case of a Registration Statement relating to
Additional Shares, the securities giving rise to the issuance of such Additional
Shares) for each 30-day period or pro rata for any portion thereof following the
date by which such Registration Statement should have been effective (the
"Blackout Period") and (ii) 1.0% of the aggregate amount invested by such
Investor for the Registrable Securities included in the applicable Registration
Statement that is not available for resales (or, in the case of a Registration
Statement relating to Additional Shares, the securities giving rise to the
issuance of such Additional Shares) for each 30-day period or pro rata for any
portion thereof that sales could not be made thereunder as provided in clause
(B) above. Such payments shall constitute the Investors' exclusive monetary
remedy for such events, but shall not affect the right of the Investors to seek
injunctive relief. The amounts payable as liquidated damages pursuant to this
paragraph shall be paid monthly within three (3) Business Days of the last day
of each month following the commencement of the Blackout Period until the
termination of the Blackout Period.

               (ii) For not more than twenty (20) consecutive days or for a
total of not more than forty-five (45) days in any twelve (12) month period, the
Company may delay the disclosure of material non-public information concerning
the Company, by suspending the use of any Prospectus included in any
registration contemplated by this Section containing such information, the
disclosure of which at the time is not, in the good faith opinion of the
Company, in the best interests of the Company (an "Allowed Delay"); provided,
that the Company shall promptly (a) notify the Investors in writing of the
existence of (but in no event, without the prior written consent of an Investor,
shall the Company disclose to such Investor any of the facts or circumstances
regarding) material non-public information giving rise to an Allowed Delay, (b)
advise the Investors in writing to cease all sales under the Registration
Statement until the end of the Allowed Delay and (c) use commercially reasonable
efforts to terminate an Allowed Delay as promptly as practicable.

          (d) Limitation on Liquidated Damages. Notwithstanding the other
provisions of this Section 2, in no event shall the Company be liable for
liquidated damages in excess of an aggregate of 24% of the aggregate purchase
price paid by the Investors pursuant to the Purchase Agreement.

     3. Company Obligations. The Company will use commercially reasonable
efforts to effect the registration of the Registrable Securities in accordance
with the terms hereof, and pursuant thereto the Company will, as expeditiously
as practicable:

          (a) use commercially reasonable efforts to cause each such
Registration Statement to become effective after 4:00 p.m. E.S.T. (the date the
Registration Statement is declared effective shall be referred to as the
"Effective Date") and to remain continuously effective for a period that will
terminate upon the earlier of (i) the date on which all Registrable Securities
covered by such Registration Statement as amended from time to time, have been
sold, and (ii) the date on which all Registrable Securities covered by such
Registration Statement may be sold

                                      C-4

<PAGE>

pursuant to Rule 144(k) (the "Effectiveness Period") and advise the Investors in
writing when the Effectiveness Period has expired;

          (b) prepare and file with the SEC such amendments and post-effective
amendments to the Registration Statement and the Prospectus as may be necessary
to keep the Registration Statement effective for the Effectiveness Period and to
comply with the provisions of the 1933 Act and the 1934 Act with respect to the
distribution of all of the Registrable Securities covered thereby;

          (c) provide copies to and permit counsel designated by the Investors,
if any, in the selling securityholder questionnaire attached hereto as Exhibit B
(the "Selling Securityholder Questionnaire") to review each Registration
Statement and all amendments and supplements thereto no fewer than seven (7)
days prior to their filing with the SEC and not file any document to which such
counsel reasonably objects;

          (d) furnish to the Investors and their legal counsel designated by the
Investors, if any, in the Selling Securityholder Questionnaire (i) promptly
after the same is prepared and publicly distributed, filed with the SEC, or
received by the Company (but not later than two (2) Business Days after the
filing date, receipt date or sending date, as the case may be) one (1) copy of
any Registration Statement and any amendment thereto, each preliminary
prospectus and Prospectus and each amendment or supplement thereto, and each
letter written by or on behalf of the Company to the SEC or the staff of the
SEC, and each item of correspondence from the SEC or the staff of the SEC, in
each case relating to such Registration Statement (other than any portion of any
thereof which contains information for which the Company has sought confidential
treatment), and (ii) such number of copies of a Prospectus, including a
preliminary prospectus, and all amendments and supplements thereto and such
other documents as each Investor may reasonably request in order to facilitate
the disposition of the Registrable Securities owned by such Investor that are
covered by the related Registration Statement;

          (e) use commercially reasonable efforts to (i) prevent the issuance of
any stop order or other suspension of effectiveness and, (ii) if such order is
issued, obtain the withdrawal of any such order at the earliest possible moment;

          (f) prior to any public offering of Registrable Securities, use
commercially reasonable efforts to register or qualify or cooperate with the
Investors and their counsel designated by the Investors, if any, in the Selling
Securityholder Questionnaire in connection with the registration or
qualification of such Registrable Securities for offer and sale under the
securities or blue sky laws of such jurisdictions requested by the Investors and
do any and all other commercially reasonable acts or things necessary or
advisable to enable the distribution in such jurisdictions of the Registrable
Securities covered by the Registration Statement; provided, however, that the
Company shall not be required in connection therewith or as a condition thereto
to (i) qualify to do business in any jurisdiction where it would not otherwise
be required to qualify but for this Section 3(f), (ii) subject itself to general
taxation in any jurisdiction where it would not otherwise be so subject but for
this Section 3(f), or (iii) file a general consent to service of process in any
such jurisdiction;

          (g) use commercially reasonable efforts to cause all Registrable
Securities covered by a Registration Statement to be listed on each securities
exchange, interdealer quotation system or other market on which similar
securities issued by the Company are then listed;

          (h) immediately notify the Investors, at any time prior to the end of
the Effectiveness Period, upon discovery that, or upon the happening of any
event as a result of which, the Prospectus includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein not misleading in light of the
circumstances then existing, and promptly prepare, file with the SEC and furnish
to such holder a supplement to or an amendment of such Prospectus as may be
necessary so that such Prospectus shall not include an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing; and

          (i) otherwise use commercially reasonable efforts to comply with all
applicable rules and regulations of the SEC under the 1933 Act and the 1934 Act,
including, without limitation, Rule 172 under the 1933 Act, file any final
Prospectus, including any supplement or amendment thereof, with the SEC pursuant
to Rule 424

                                      C-5

<PAGE>

under the 1933 Act prior to 9:30 a.m. E.S.T. on the Trading Day immediately
following the Effective Date, promptly inform the Investors in writing if, at
any time during the Effectiveness Period, the Company does not satisfy the
conditions specified in Rule 172 and, as a result thereof, the Investors are
required to deliver a Prospectus in connection with any disposition of
Registrable Securities and take such other actions as may be reasonably
necessary to facilitate the registration of the Registrable Securities
hereunder; and make available to its security holders, as soon as reasonably
practicable, but not later than the Availability Date (as defined below), an
earnings statement covering a period of at least twelve (12) months, beginning
after the effective date of each Registration Statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the 1933 Act,
including Rule 158 promulgated thereunder (for the purpose of this subsection
3(i), "Availability Date" means the 45th day following the end of the fourth
fiscal quarter that includes the effective date of such Registration Statement,
except that, if such fourth fiscal quarter is the last quarter of the Company's
fiscal year, "Availability Date" means the 90th day after the end of such fourth
fiscal quarter).

          (j) with a view to making available to the Investors the benefits of
Rule 144 (or its successor rule) and any other rule or regulation of the SEC
that may at any time permit the Investors to sell shares of Common Stock to the
public without registration, the Company covenants and agrees to: (i) make and
keep public information available, as those terms are understood and defined in
Rule 144, until the earlier of (A) six months after such date as all of the
Registrable Securities may be resold pursuant to Rule 144(k) or any other rule
of similar effect or (B) such date as all of the Registrable Securities shall
have been resold; (ii) file with the SEC in a timely manner all reports and
other documents required of the Company under the 1934 Act; and (iii) furnish to
each Investor upon request, as long as such Investor owns any Registrable
Securities, (A) a written statement by the Company that it has complied with the
reporting requirements of the 1934 Act, (B) a copy of the Company's most recent
Annual Report on Form 10-K or Quarterly Report on Form 10-Q, and (C) such other
information as may be reasonably requested in order to avail such Investor of
any rule or regulation of the SEC that permits the selling of any such
Registrable Securities without registration.

     4. Due Diligence Review; Information. The Company shall make available,
during normal business hours, for inspection and review by the Investors,
advisors to and representatives of the Investors (who may or may not be
affiliated with the Investors and who are reasonably acceptable to the Company),
all financial and other records, all SEC Filings (as defined in the Purchase
Agreement) and other filings with the SEC, and all other corporate documents and
properties of the Company as may be reasonably necessary for the purpose of such
review, and cause the Company's officers, directors and employees, within a
reasonable time period, to supply all such information reasonably requested by
the Investors or any such representative, advisor or underwriter in connection
with such Registration Statement (including, without limitation, in response to
all questions and other inquiries reasonably made or submitted by any of them),
prior to and from time to time after the filing and effectiveness of the
Registration Statement for the sole purpose of enabling the Investors and such
representatives, advisors and underwriters and their respective accountants and
attorneys to conduct initial and ongoing due diligence with respect to the
Company and the accuracy of such Registration Statement.

          The Company shall not disclose material nonpublic information to the
Investors, or to advisors to or representatives of the Investors, unless prior
to disclosure of such information the Company identifies such information as
being material nonpublic information and provides the Investors, such advisors
and representatives with the opportunity to accept or refuse to accept such
material nonpublic information for review and any Investor wishing to obtain
such information enters into an appropriate confidentiality agreement with the
Company with respect thereto.

     5. Obligations of the Investors.

          (a) Each Investor has furnished to the Company a Selling
Securityholder Questionnaire and shall furnish in writing to the Company such
additional information regarding itself, the Registrable Securities held by it
and the intended method of disposition of the Registrable Securities held by it,
as shall be reasonably required to effect the registration of such Registrable
Securities and shall execute such documents in connection with such registration
as the Company may reasonably request. At least five (5) Business Days prior to
the first anticipated filing date of any Registration Statement, the Company
shall notify each Investor of the information the Company requires from such
Investor, to the extent not included in the Selling Securityholder
Questionnaire, if such Investor elects to have any of the Registrable Securities
included in the Registration Statement. An Investor shall provide

                                      C-6

<PAGE>

such information to the Company at least two (2) Business Days prior to the
first anticipated filing date of such Registration Statement if such Investor
elects to have any of the Registrable Securities included in the Registration
Statement.

          (b) Each Investor, by its acceptance of the Registrable Securities
agrees to cooperate with the Company as reasonably requested by the Company in
connection with the preparation and filing of a Registration Statement
hereunder, unless such Investor has notified the Company in writing of its
election to exclude all of its Registrable Securities from such Registration
Statement.

          (c) Each Investor agrees that, upon receipt of any notice from the
Company of either (i) the commencement of an Allowed Delay pursuant to Section
2(c)(ii) or (ii) the happening of an event pursuant to Section 3(h) hereof, such
Investor will immediately discontinue disposition of Registrable Securities
pursuant to the Registration Statement covering such Registrable Securities,
until the Investor is advised by the Company that such dispositions may again be
made.

     6. Indemnification.

          (a) Indemnification by the Company. The Company will indemnify and
hold harmless each Investor and its officers, directors, members, employees and
agents, successors and assigns, and each other person, if any, who controls such
Investor within the meaning of the 1933 Act, against any losses, claims, damages
or liabilities, joint or several, to which they may become subject under the
1933 Act or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon: (i) any untrue
statement or omission or alleged untrue statement or omission of any material
fact in any Registration Statement, any preliminary Prospectus or final
Prospectus, or any amendment or supplement thereof required to be stated therein
or necessary to make the statements therein not misleading; (ii) any blue sky
application or other document executed by the Company specifically for that
purpose or based upon written information furnished by the Company filed in any
state or other jurisdiction in order to qualify any or all of the Registrable
Securities under the securities laws thereof (any such application, document or
information herein called a "Blue Sky Application"); (iii) any violation by the
Company or its agents of any rule or regulation promulgated under the 1933 Act
applicable to the Company or its agents and relating to action or inaction
required of the Company in connection with such registration; or (iv) any
failure to register or qualify the Registrable Securities included in any such
Registration in any state where the Company or its agents has affirmatively
undertaken or agreed in writing that the Company will undertake such
registration or qualification on an Investor's behalf and will reimburse such
Investor, and each such officer, director or member and each such controlling
person for any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that the Company will not be liable in any such case
if and to the extent that any such loss, claim, damage or liability arises out
of or is based upon (i) such Investor's failure to comply with the prospectus
delivery requirements of the Securities Act at any time when the Company does
not meet the conditions for use of Rule 172, has advised the Investor in writing
that the Company does not meet such conditions and that therefore the Investor
is required to deliver a Prospectus in connection with any sale or other
disposition of Registrable Securities and has provided such Investor with a
current Prospectus for such use, (ii) an untrue statement or alleged untrue
statement or omission or alleged omission so made in conformity with information
furnished by such Investor or any such controlling person in writing
specifically for use in such Registration Statement or Prospectus or (iii) the
use by an Investor of an outdated or defective Prospectus after the Company has
notified the Investor that such Prospectus is outdated or defective and the use
of a corrected or updated Prospectus would have avoided such losses, claims,
damages, liabilities or expenses.

          (b) Indemnification by the Investors. Each Investor agrees, severally
but not jointly, to indemnify and hold harmless, to the fullest extent permitted
by law, the Company, its directors, officers, employees, stockholders and each
person who controls the Company (within the meaning of the 1933 Act) against any
losses, claims, damages, liabilities and expense (including reasonable attorney
fees) resulting from (i) such Investor's failure to comply with the prospectus
delivery requirements of the Securities Act at any time when the Company does
not meet the conditions for use of Rule 172, has advised the Investor in writing
that the Company does not meet such conditions and that therefore the Investor
is required to deliver a Prospectus in connection with any sale or other
disposition of Registrable Securities and has provided such Investor with a
current Prospectus for such use, (ii) the use by an Investor of an outdated or
defective Prospectus after the Company has notified the Investor that

                                      C-7

<PAGE>

such Prospectus is outdated or defective and the use of a corrected or updated
Prospectus would have avoided such losses, claims, damages, liabilities or
expenses, and (iii) any untrue statement of a material fact or any omission of a
material fact required to be stated in the Registration Statement or Prospectus
or preliminary Prospectus or amendment or supplement thereto or necessary to
make the statements therein not misleading, to the extent, but only to the
extent that such untrue statement or omission is contained in any information
furnished in writing by such Investor to the Company specifically for inclusion
in such Registration Statement or Prospectus or amendment or supplement thereto.
In no event shall the liability of an Investor be greater in amount than the
dollar amount of the proceeds (net of all expense paid by such Investor in
connection with any claim relating to this Section 6 and the amount of any
damages such Investor has otherwise been required to pay by reason of such
untrue statement or omission) received by such Investor upon the sale of the
Registrable Securities included in the Registration Statement giving rise to
such indemnification obligation.

          (c) Conduct of Indemnification Proceedings. Any person entitled to
indemnification hereunder shall (i) give prompt notice to the indemnifying party
of any claim with respect to which it seeks indemnification and (ii) permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party; provided that any person entitled to
indemnification hereunder shall have the right to employ separate counsel and to
participate in the defense of such claim, but the fees and expenses of such
counsel shall be at the expense of such person unless (a) the indemnifying party
has agreed to pay such fees or expenses, or (b) the indemnifying party shall
have failed to assume the defense of such claim and employ counsel reasonably
satisfactory to such person or (c) in the reasonable judgment of any such
person, based upon written advice of its counsel, a conflict of interest exists
between such person and the indemnifying party with respect to such claims (in
which case, if the person notifies the indemnifying party in writing that such
person elects to employ separate counsel at the expense of the indemnifying
party, the indemnifying party shall not have the right to assume the defense of
such claim on behalf of such person); and provided, further, that the failure of
any indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations hereunder, except to the extent that such
failure to give notice shall materially adversely affect the indemnifying party
in the defense of any such claim or litigation. It is understood that the
indemnifying party shall not, in connection with any proceeding in the same
jurisdiction, be liable for fees or expenses of more than one separate firm of
attorneys at any time for all such indemnified parties. No indemnifying party
will, except with the consent of the indemnified party, consent to entry of any
judgment or enter into any settlement that does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect of such claim or litigation.

          (d) Contribution. If for any reason the indemnification provided for
in the preceding paragraphs (a) and (b) is unavailable to an indemnified party
or insufficient to hold it harmless, other than as expressly specified therein,
then the indemnifying party shall contribute to the amount paid or payable by
the indemnified party as a result of such loss, claim, damage or liability in
such proportion as is appropriate to reflect the relative fault of the
indemnified party and the indemnifying party, as well as any other relevant
equitable considerations. No person guilty of fraudulent misrepresentation
within the meaning of Section 11(f) of the 1933 Act shall be entitled to
contribution from any person not guilty of such fraudulent misrepresentation. In
no event shall the contribution obligation of a holder of Registrable Securities
be greater in amount than the dollar amount of the proceeds (net of all expenses
paid by such holder in connection with any claim relating to this Section 6 and
the amount of any damages such holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission) received by it upon the sale of the Registrable Securities giving rise
to such contribution obligation.

     7. Miscellaneous.

          (a) Amendments and Waivers. This Agreement may be amended only by a
writing signed by the Company and the Required Investors. The Company may take
any action herein prohibited, or omit to perform any act herein required to be

such person, provided that such Investor complies with all laws applicable
thereto and provides written notice of assignment to the Company promptly after
such assignment is effected.

          (d) Assignments and Transfers by the Company. This Agreement may not
be assigned by the Company (whether by operation of law or otherwise) without
the prior written consent of the Required Investors, provided, however, that the
Company may assign its rights and delegate its duties hereunder to any surviving
or successor corporation in connection with a merger or consolidation of the
Company with another corporation, or a sale, transfer or other disposition of
all or substantially all of the Company's assets to another corporation, without
the prior written consent of the Required Investors, after notice duly given by
the Company to each Investor.

          (e) Benefits of the Agreement. The terms and conditions of this
Agreement shall inure to the benefit of and be binding upon the respective
permitted successors and assigns of the parties. Nothing in this Agreement,

obligations, or liabilities under or by reason of this Agreement, except as
expressly provided in this Agreement.

          (f) Counterparts; Faxes. This Agreement may be executed in two or more

Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

          (h) Severability. Any provision of this Agreement that is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof but shall be interpreted as if it
were written so as to be enforceable to the maximum extent permitted by
applicable law, and any such prohibition or unenforceability in any jurisdiction
shall not invalidate or render unenforceable such provision in any other
jurisdiction. To the extent permitted by applicable law, the parties hereby
waive any provision of law which renders any provisions hereof prohibited or
unenforceable in any respect.

          (i) Further Assurances. The parties shall execute and deliver all such
further instruments and documents and take all such other actions as may

matter.

          (k) Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This
Agreement shall be governed by, and construed in accordance with, the internal
laws of the State of New York without regard to the choice of law principles
thereof. Each of the parties hereto irrevocably submits to the exclusive

or proceeding brought in such courts and irrevocably waives any claim that any
such suit, action or proceeding brought in any such court has been brought in an
inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO

                              PLAN OF DISTRIBUTION

     The selling stockholders, which as used herein includes donees, pledgees,
transferees or other successors-in-interest selling shares of common stock or
interests in shares of common stock received after the date of this prospectus
from a selling stockholder as a gift, pledge, partnership distribution or other
transfer, may, from time to time, sell, transfer or otherwise dispose of any or
all of their shares of common stock or interests in shares of common stock on
any stock exchange, market or trading facility on which the shares are traded or
in private transactions. These dispositions may be at fixed prices, at
prevailing market prices at the time of sale, at prices related to the
prevailing market price, at varying prices determined at the time of sale, or at
negotiated prices.

     The selling stockholders may use any one or more of the following methods
when disposing of shares or interests therein:

     -    ordinary brokerage transactions and transactions in which the
          broker-dealer solicits purchasers;

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

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

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

     -    privately negotiated transactions;

     -    short sales effected after the date the registration statement of
          which this Prospectus is a part is declared effective by the SEC;

     -    through the writing or settlement of options or other hedging
          transactions, whether through an options exchange or otherwise;

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

     -    a combination of any such methods of sale; and

     -    any other method permitted by applicable law.

     The selling stockholders may, from time to time, pledge or grant a security
interest in some or all of the shares of common stock owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell the shares of common stock, from time to time, under
this prospectus, or under an amendment to this prospectus under Rule 424(b)(3)
or other applicable provision of the Securities Act amending the list of selling
stockholders to include the pledgee, transferee or other successors in interest
as selling stockholders under this prospectus. The selling stockholders also may
transfer the shares of common stock in other circumstances, in which case the
transferees, pledgees or other successors in interest will be the selling
beneficial owners for purposes of this prospectus.

     In connection with the sale of our common stock or interests therein, the
selling stockholders may enter into hedging transactions with broker-dealers or
other financial institutions, which may in turn engage in short sales of the
common stock in the course of hedging the positions they assume. The selling
stockholders may also sell shares of our common stock short and deliver these
securities to close out their short positions, or loan or pledge the common
stock to broker-dealers that in turn may sell these securities. The selling
stockholders may also enter into option or other transactions with
broker-dealers or other financial institutions or the creation of one or more
derivative securities which require the delivery to such broker-dealer or other
financial institution of shares offered

by this prospectus, which shares such broker-dealer or other financial
institution may resell pursuant to this prospectus (as supplemented or amended
to reflect such transaction).

     The aggregate proceeds to the selling stockholders from the sale of the
common stock offered by them will be the purchase price of the common stock less
discounts or commissions, if any. Each of the selling stockholders reserves the
right to accept and, together with their agents from time to time, to reject, in
whole or in part, any proposed purchase of common stock to be made directly or
through agents. We will not receive any of the proceeds from this offering. Upon
any exercise of the warrants by payment of cash, however, we will receive the
exercise price of the warrants.

     The selling stockholders also may resell all or a portion of the shares in
open market transactions in reliance upon Rule 144 under the Securities Act of
1933, provided that they meet the criteria and conform to the requirements of
that rule.

     The selling stockholders and any underwriters, broker-dealers or agents
that participate in the sale of the common stock or interests therein may be
"underwriters" within the meaning of Section 2(11) of the Securities Act. Any
discounts, commissions, concessions or profit they earn on any resale of the
shares may be underwriting discounts and commissions under the Securities Act.
Selling stockholders who are "underwriters" within the meaning of Section 2(11)
of the Securities Act will be subject to the prospectus delivery requirements of
the Securities Act.

     To the extent required, the shares of our common stock to be sold, the
names of the selling stockholders, the respective purchase prices and public
offering prices, the names of any agents, dealer or underwriter, any applicable
commissions or discounts with respect to a particular offer will be set forth in
an accompanying prospectus supplement or, if appropriate, a post-effective
amendment to the registration statement that includes this prospectus.

     In order to comply with the securities laws of some states, if applicable,
the common stock may be sold in these jurisdictions only through registered or
licensed brokers or dealers. In addition, in some states the common stock may
not be sold unless it has been registered or qualified for sale or an exemption
from registration or qualification requirements is available and is complied
with.

     We have advised the selling stockholders that the anti-manipulation rules
of Regulation M under the Exchange Act may apply to sales of shares in the
market and to the activities of the selling stockholders and their affiliates.
In addition, to the extent applicable we will make copies of this prospectus (as
it may be supplemented or amended from time to time) available to the selling
stockholders for the purpose of satisfying the prospectus delivery requirements
of the Securities Act. The selling stockholders may indemnify any broker-dealer
that participates in transactions involving the sale of the shares against
certain liabilities, including liabilities arising under the Securities Act.

     We have agreed to indemnify the selling stockholders against liabilities,
including liabilities under the Securities Act and state securities laws,
relating to the registration of the shares offered by this prospectus.

     We have agreed with the selling stockholders to keep the registration
statement of which this prospectus constitutes a part effective until the
earlier of (1) such time as all of the shares covered by this prospectus have
been disposed of pursuant to and in accordance with the registration statement
or (2) the date on which the shares may be sold pursuant to Rule 144(k) of the
Securities Act.

following (collectively, the "Excluded Collateral"):

     (1) vehicles subject to a certificate of title statute; and

all assets of such Grantor or words of similar effect, regardless of whether any
particular asset comprised in the Collateral falls within the scope of Article 9
of the Uniform Commercial Code of the State or such jurisdiction, or (ii) as

                                       D-3

<PAGE>

being of an equal or lesser scope or with greater detail, and (b) contain any
other information required by part 5 of Article 9 of the Uniform Commercial Code
of the State for the sufficiency or filing office acceptance of any financing
statement or amendment, including whether such Grantor is an organization, the

Grantor. The Grantors agree to furnish any such information to the Agent and the
other Secured Parties promptly upon request. Each Grantor also ratifies its
authorization for the Agent to have filed in any Uniform Commercial Code
jurisdiction financing statements or amendments thereto if filed prior to the
date hereof.

4. OTHER ACTIONS. Further to insure the attachment, perfection and first
priority (subject to Permitted Liens) of, and the ability of the Agent to
enforce, the Agent's first priority security interest in the Collateral, the
Grantors agree, in each case at the Grantor's own expense, to take the following
actions with respect to the following Collateral:

     4.1 Promissory Notes and Tangible Chattel Paper. If any Grantor shall at
any time hold or acquire any promissory notes or tangible chattel paper, such
Grantor shall forthwith endorse, pledge and deliver the same to the Agent,
accompanied by such instruments of transfer or assignment duly executed in blank
as the Agent may from time to time specify.

     4.2 Deposit Accounts. For each deposit account (each, a "Deposit Account")
that any Grantor at any time opens or maintains at any depository bank (each, a
"Depository Bank"), the Grantor shall, at the Agent's or any other Secured
Party's reasonable request and option, pursuant to an agreement (each, a
"Deposit Account Control Agreement") in form and substance satisfactory to the
Agent and the Requisite Purchasers (as defined in Section 30.3(b)), upon an
Event of Default either (a) cause the Depositary Bank to agree to comply at any
time with instructions from the Agent to such Depositary Bank directing the
disposition of funds from time to time credited to such Deposit Account, without
further consent of the Grantor, or (b) arrange for the Agent to become the
customers of the Depositary Bank with respect to the Deposit Account, with the
Grantors being permitted, only with the consent of the Agent and the Requisite
Purchasers, to exercise rights to withdraw funds from such Deposit Account. The
Agent agrees with the Grantors that the Agent shall not give any such
instructions or withhold any withdrawal rights from the Grantors, unless an
Event of Default has occurred and is continuing, or, after giving effect to any
withdrawal not otherwise permitted by the Transaction Documents, would occur.
The provisions of this paragraph shall not apply to (i) any Deposit Account for
which the Grantors, the Depositary Bank and the Agent and/or the other Secured
Parties have entered into a cash collateral agreement specially negotiated among
any Grantor, the Depositary Bank and the Agent and/or the other Secured Parties
for the specific purpose set forth therein (ii) Deposit Accounts for which any
Secured Party is the depositary, and (iii) any Deposit Account which holds
exclusively sales tax and/or withholding remittances.

     4.3 Investment Property. If any Grantor shall at any time hold or acquire
any certificated securities, the Grantor shall forthwith endorse, pledge and
deliver the same to the Agent, accompanied by such instruments of transfer or
assignment duly executed in blank as the Agent may from time to time specify. If
any securities now or hereafter acquired by any Grantor are uncertificated and
are issued to the Grantor or its nominee directly by the issuer thereof, the
Grantor shall immediately notify the Agent and the other Secured Parties thereof
and, at the Agent's or any other Secured Party's reasonable request and option,
pursuant to an agreement in

                                       D-4

<PAGE>

form and substance satisfactory to the Agent and the Requisite Purchasers,
either (a) cause the issuer to agree to comply with instructions from the Agent
as to such securities, without further consent of the Grantor or such nominee,
or (b) arrange for the Agent (on behalf of the Secured Parties) to become the
registered owners of the securities. If any securities, whether certificated or
uncertificated, or other investment property now or hereafter acquired by any
Grantor are held by the Grantor or its nominee through a securities intermediary
or commodity intermediary, the Grantor shall immediately notify the Agent and
the other Secured Parties thereof and, at the Agent's or any other Secured
Party's reasonable request and option, pursuant to an agreement in form and
substance satisfactory to the Agent and the Requisite Purchasers, either (i)
cause such securities intermediary or (as the case may be) commodity
intermediary to agree to comply with entitlement orders or other instructions
from the Agent to such securities intermediary as to such securities or other
investment property, or (as the case may be) to apply any value distributed on

intermediary, in each case without further consent of the Grantor or such
nominee, or (ii) in the case of financial assets or other investment property
held through a securities intermediary, arrange for the Agent (on behalf of the
Secured Parties) to become the entitlement holders with respect to such
investment property, with the Grantor being permitted, only with the consent of

that the Agent shall not give any such entitlement orders or instructions or
directions to any such issuer, securities intermediary or commodity
intermediary, and shall not withhold its consent to the exercise of any
withdrawal or dealing rights by the Grantors, unless an Event of Default has
occurred and is continuing, or, after giving effect to any such investment and
withdrawal rights not otherwise permitted by the Transaction Documents, would
occur. The provisions of this paragraph shall not apply to any financial assets
credited to a securities account for which any Secured Party is the securities

bailee, in form and substance satisfactory to the Agent and the Requisite
Purchasers, that the bailee holds such Collateral for the benefit of the Agent
(on behalf of the Secured Parties) and shall act upon the instructions of the
Agent, without the further consent of the Grantor. The Agent agrees with the
Grantors that the Agent shall not give any such instructions unless an Event of
Default has occurred and is continuing or would occur after taking into account
any action by the Grantors with respect to the bailee.

     4.5 Electronic Chattel Paper and Transferable Records. If any Grantor at
any time holds or acquires an interest in any electronic chattel paper, the
Grantor shall promptly notify the Agent and the other Secured Parties thereof
and, at the reasonable request of the Agent or any other Secured Party, shall
take such action as the Agent or such other Secured Party may reasonably request
to vest in the Agent control, under Section9-105 of the Uniform Commercial Code,
of such electronic chattel paper. The Agent agrees with the Grantors that the
Agent will arrange, pursuant to procedures satisfactory to the Agent and the
Requisite Purchasers and so long as such procedures will not result in the
Agent's loss of control, for the Grantors to make alterations to the electronic
chattel paper or transferable record permitted under UCC Section9-105, unless an
Event of Default has occurred and is continuing or would occur after taking into

                                       D-5

<PAGE>

account any action by the Grantors with respect to such electronic chattel paper
or transferable record.

     4.6 Letter-of-credit Rights. If any Grantor is at any time a beneficiary
under a letter of credit now or hereafter issued in favor of the Grantor, the
Grantor shall promptly notify the Agent and the other Secured Parties thereof
and, at the reasonable request and option of the Agent or any Secured Party, the
Grantor shall, pursuant to an agreement in form and substance satisfactory to
the Agent and the Requisite Purchasers, either (i) use commercially reasonable
efforts (including, but not limited to, the payment of customary transfer and
assignment fees) to have the issuer and any confirmer of such letter of credit
to consent to an assignment to the Agent of the proceeds of any drawing under
the letter of credit or (ii) use commercially reasonable efforts (including, but
not limited to, the payment of customary transfer and assignment fees) to have
the Agent become the transferee beneficiaries of the letter of credit, with the
Agent agreeing, in each case, that the proceeds of any drawing under the letter
to credit are to be applied as provided in the Notes.

     4.7 Commercial Tort Claims. If any Grantor shall at any time hold or
acquire a commercial tort claim, the Grantor shall immediately notify the Agent
and the other Secured Parties in a writing signed by the Grantor of the brief
details thereof and grant to the Agent (on behalf of the Secured Parties) in
such writing a security interest therein and in the proceeds thereof, all upon
the terms of this Agreement, with such writing to be in form and substance
satisfactory to the Agent and the Requisite Purchasers.

5. OTHER ACTIONS AS TO ANY AND ALL COLLATERAL. The Grantors further agree to
take any other action reasonably requested by the Agent or any other Secured
Party to insure the attachment, perfection and first priority (subject to
Permitted Liens) of, and the ability of the Agent (on behalf of the Secured
Parties) to enforce, the Secured Parties' security interest in any and all of
the Collateral including, without limitation, (a) executing, delivering and,
where appropriate, filing financing statements and amendments relating thereto
under the Uniform Commercial Code, to the extent, if any, that any Grantor's
signature thereon is required therefor, (b) causing the Agent's name to be noted

the Agent to enforce, the Agent's security interest in such Collateral, (c)
complying with any provision of any statute, regulation or treaty of the United
States as to any Collateral if compliance with such provision is a condition to
attachment, perfection or priority of, or ability of the Agent to enforce, the
Agent's security interest in such Collateral, (d) obtaining governmental and
other third party consents and approvals, including without limitation any
consent of any licensor, lessor or other person obligated on Collateral, (e)
obtaining waivers from landlords in form and substance satisfactory to the Agent

applicable in any relevant jurisdiction, or by other law as applicable in any

11. INSURANCE.

     11.1 MAINTENANCE OF INSURANCE. Each Grantor will maintain with financially
sound and reputable insurers insurance with respect to its properties and
business against such casualties and contingencies as shall be in accordance
with general practices of businesses engaged in similar activities in similar
geographic areas; provided, however, that the Borrower shall at all times
maintain with financially sound and reputable insurers such insurance in amounts
not less than the insurance maintained by the Borrower as of the date hereof,
except with the Purchasers' prior written consent (which will not be
unreasonably withheld or delayed). Such insurance shall be in such minimum
amounts that the Grantor will not be deemed a co-insurer under applicable
insurance laws, regulations and policies and otherwise shall be in such amounts,
contain such terms, be in such forms and be for such periods as may be
reasonably satisfactory to the Agent and the Requisite Purchasers. In addition,

     11.2 INSURANCE PROCEEDS. The proceeds of any casualty insurance in respect
of any casualty loss of any of the Collateral shall, subject to the rights, if
any, of other parties with a prior interest in the property covered thereby, (i)
so long as no Default or Event of Default has occurred and is continuing and to
the extent that the amount of such proceeds is less than $150,000, be disbursed
to the Grantor for direct application by the Grantor solely to the repair or
replacement of the Grantor's property so damaged or destroyed and (ii) in all
other circumstances, be held by the Purchasers as cash collateral for the
Obligations and (except to the extent disbursed pursuant to the next sentence)
may be applied to the Obligations. The Agent may, at its sole option, disburse
from time to time all or any part of such proceeds so held as cash collateral,
upon such terms and conditions as the Agent may reasonably prescribe, for direct
application by the Grantor solely to the repair or replacement of the Grantor's
property so damaged or destroyed, or the Agent may apply all or any part of such
proceeds to the Obligations.

of insurance and policies evidencing compliance with the foregoing insurance
provision.

12. COLLATERAL PROTECTION EXPENSES; PRESERVATION OF COLLATERAL.

     12.1 EXPENSES INCURRED BY THE SECURED PARTIES. In their discretion, the
Agent or any other Secured Party may, if any Grantor fails to do so, discharge
encumbrances at any time levied or placed on any of the Collateral (other than
to the extent constituting Permitted Liens), make repairs thereto and pay any
necessary filing fees or, if any Grantor fails to do so, insurance premiums.
Each Grantor agrees to reimburse the Agent or such other applicable Secured
Party on demand for any and all expenditures so made. Neither the Agent nor any
other Secured Party shall have any obligation to the Grantors to make any such
expenditures, nor shall the making thereof relieve the Grantor of any default.
Any expenses incurred under this Section 12 shall constitute Obligations.

     12.2 SECURED PARTIES' OBLIGATIONS AND DUTIES. Anything herein to the
contrary notwithstanding, each Grantor shall remain liable under each contract
or agreement comprised in the Collateral to be observed or performed by the
Grantor thereunder. The Secured Parties shall not have any obligation or
liability under any such contract or agreement by reason of or arising out of
this Agreement or the receipt by the Agent or any other Secured Party of any
payment relating to any of the Collateral, nor shall the Agent or any other
Secured Party be obligated in any manner to perform any of the obligations of
the Grantor under or pursuant to any such contract or agreement, to make inquiry
as to the nature or sufficiency of any payment received by the Agent or any
other Secured Party in respect of the Collateral or as to the sufficiency of any
performance by any party under any such contract or agreement, to present or
file any claim, to take any action to enforce any performance or to collect the
payment of any amounts which may have been assigned to the Agent or any other
Secured Party or to which the Agent or any other Secured Party may be entitled
at any time or times. The Agent's (and any other Secure

                                      D-10

<PAGE>

Party so receiving Collateral) sole duty with respect to the custody, safe
keeping and physical preservation of the Collateral in its possession, under
Section9-207 of the Uniform Commercial Code of the State or otherwise, shall be
to deal with such Collateral in the same manner as the Agent (or such other
Secured Party) deals with similar property for its own account.

13. SECURITIES AND DEPOSITS. The Agent may at any time following and during the
continuance of an Event of Default, at its option, transfer to itself or any
nominee any securities constituting Collateral, receive any income thereon and
hold such income as additional Collateral or apply it to the Obligations.
Whether or not any Obligations are due, the Agent may following and during the
continuance of an Event of Default demand, sue for, collect, or make any
settlement or compromise which it deems desirable with respect to the
Collateral. Regardless of the adequacy of Collateral or any other security for
the Obligations, any deposits or other sums at any time credited by or due from
the Agent to the Grantors may at any time be applied to or set off against any
of the Obligations then due and owing.

14. NOTIFICATION TO ACCOUNT DEBTORS AND OTHER PERSONS OBLIGATED ON COLLATERAL.
If an Event of Default shall have occurred and be continuing, the Grantors
shall, at the reasonable request of the Agent or any other Secured Party, notify
account debtors and other persons obligated on any of the Collateral of the
security interest of the Agent in any account, chattel paper, general
intangible, instrument or other Collateral and that payment thereof is to be
made directly to the Agent or to any financial institution designated by the
Agent as its agent therefor, and the Agent may, if an Event of Default shall
have occurred and be continuing, without notice to or demand upon the Grantor,
so notify account debtors and other persons obligated on Collateral. After the
making of such a request or the giving of any such notification, the Grantors
shall hold any proceeds of collection of accounts, chattel paper, general
intangibles, instruments and other Collateral received by the Grantor as trustee
for the Agent without commingling the same with other funds of the Grantor and
shall turn the same over to the Agent in the identical form received, together
with any reasonably necessary or advisable endorsements or assignments. The
Agent shall apply the proceeds of collection of accounts, chattel paper, general
intangibles, instruments and other Collateral received by the Agent to the
Obligations, such proceeds to be immediately entered after final payment in cash
or other immediately available funds of the items giving rise to them.

15. INVESTMENT PROPERTY. (i) The Grantors, at their cost and expense (including
the cost and expense of any of the following referenced consents, approvals
etc.) will promptly execute and deliver or cause the execution and delivery of
all applications, certificates, instruments, registration statements, and all
other documents and papers the Purchasers may reasonably request during the
continuance of an Event of Default in connection with the obtaining of any
consent, approval, registration, qualification, permit, license, accreditation,
or authorization of any other official body or other Person reasonably necessary
or appropriate for the effective exercise of any rights hereunder or under the
other Transaction Documents. Without limiting the generality of the foregoing,
the Grantors agree that in the event the Agent shall exercise its rights
hereunder or pursuant to the other Transaction Documents during the continuance
of an Event of Default, to sell, transfer, or otherwise dispose of, or vote,
consent, operate, or take any other action in connection with any of the
Collateral, the Grantors shall execute and deliver (or cause to be executed and
delivered) all applications, certificates, assignments and other documents that
the Agent reasonably requests to facilitate such actions and shall otherwise
promptly, fully, and

                                      D-11

<PAGE>

diligently cooperate with the Agent and any other Persons in making any
application for the prior consent or approval of any official body or any other
Person to the exercise by the Purchasers of any such rights relating to all or
any of the Collateral.

          (i) The Grantors agree promptly upon the occurrence and continuance of
an Event of Default and without any request therefor by the Agent or any other
Secured Party, so long as such Event of Default shall continue, to deliver
(properly endorsed where required hereby or reasonably requested by the Agent or
any other Secured Party) to the Agent all Dividends and Distributions with
respect to Investment Property and all proceeds of the Collateral, in each case
thereafter received by the Grantor, all of which shall be held by the Agent as
additional Collateral.

          (ii) Except when an Event of Default has occurred and is continuing,
the Grantors may continue to vote all Investment Property included in the
Collateral except in a manner which is inconsistent or in violation of the
Transaction Documents. The Grantors agree promptly upon the occurrence and
during the continuance of an Event of Default, (i) that the Agent may exercise
(to the exclusion of the Grantor) the voting power and all other incidental
rights of ownership with respect to any Collateral constituting Investment
Property of the Grantor and the Grantor hereby grants the Agent an irrevocable
proxy, exercisable under such circumstances, to vote such Investment Property;
and (ii) that it shall promptly deliver to the Agent such additional proxies and
other documents as may be reasonably necessary to allow the Agent to exercise
such voting power.

          (iii) All Dividends, Distributions, interest, principal, cash
payments, payment intangibles and proceeds which may at any time and from time
to time be held by any Grantor but which the Grantor is then obligated to
deliver to the Agent, shall, until delivery to the Agent, be held by the Grantor
separate and apart from its other property in trust for the Agent. The Agent
agrees that unless an Event of Default shall have occurred and be continuing,
the Grantors will have the exclusive voting power with respect to any Investment
Property constituting the Grantor's Collateral and the Agent will, upon the
written request of any Grantor, promptly deliver such proxies and other
documents, if any, as shall be reasonably requested by the Grantor which are
reasonably necessary to allow the Grantor to exercise that voting power;
provided that no vote shall be cast, or consent, waiver, or ratification given,
or action taken by the Grantor that would violate any provision of any
Transaction Document.

     The Grantors hereby acknowledge that the sale by the Agent of any
Investment Property pursuant to the terms hereof in compliance with the
Securities Act, as well as applicable "Blue Sky" or other state securities laws
may require strict limitations as to the manner in which the Agent or any
subsequent transferee of the Investment Property may dispose thereof. The
Grantors acknowledge and agree that, to protect the Agent's interests, it may be
necessary to sell the Investment Property at a price less than the maximum price
attainable if a sale were delayed or made in another manner, such as a public
offering under the Securities Act. The Grantors do not have an objection to a
sale in such manner and the Grantors agree that the Agent does not have an
obligation to obtain the maximum possible price for all or any part of the
Investment Property. Without limiting the generality of the foregoing, the
Grantors agree that the Agent may, pursuant to the terms hereof and subject to
applicable law, from time to time attempt to sell all or any part of the
Investment Property by a private placement, restricting the bidders and

                                      D-12

<PAGE>

prospective purchasers to those Persons who will represent and agree that they
are purchasing for investment only and not for distribution. In so doing, the
Agent may solicit offers to buy the Investment Property or any part thereof for
cash from a limited number of investors deemed by the Agent, in its reasonable
judgment, to be institutional investors or other responsible Persons who might
be interested in purchasing the Investment Property. If the Agent shall solicit
such offers, then acceptance by Purchasers of one of the offers shall be deemed
to be a commercially reasonable method of disposition of the Collateral.

16. POWER OF ATTORNEY.

     16.1 APPOINTMENT AND POWERS OF PURCHASERS. The Grantors hereby irrevocably
constitute and appoint the Agent and any officer or agent thereof, with full
power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of the Grantors or in the
Agent's own name, for the purpose of carrying out the terms of this Agreement,
to take any and all appropriate action and to execute any and all documents and
instruments that may be reasonably necessary or desirable to accomplish the
purposes of this Agreement and, without limiting the generality of the
foregoing, hereby gives said attorney the power and right, on behalf of the
Grantors, without notice to or assent by the Grantors, to do the following:

          (a) upon the occurrence and during the continuance of an Event of
Default, generally to sell, transfer, pledge, make any agreement with respect to
or otherwise deal with any of the Collateral in such manner as is consistent
with the Uniform Commercial Code of the State and as fully and completely as
though the Agent was the absolute owners thereof for all purposes, and to do at
the Grantors' expense, at any time, or from time to time, all acts and things
which the Agent deems reasonably necessary or advisable to protect, preserve or
realize upon the Collateral and the Agent's security interest therein, in order
to effect the intent of this Agreement, all as fully and effectively as the
Grantor might do, including, without limitation, (i) the filing and prosecuting
of registration and transfer applications with the appropriate federal or local
agencies or authorities with respect to trademarks, copyrights and patentable
inventions and processes, (ii) upon written notice to the Grantors, the exercise
of voting rights with respect to voting securities, which rights may be
exercised, if the Agent so elects, with a view to causing the liquidation in a
commercially reasonable manner of assets of the issuer of any such securities
and (iii) the execution, delivery and recording, in connection with any sale or
other disposition of any Collateral, of the endorsements, assignments or other
instruments of conveyance or transfer with respect to such Collateral; and

          (b) to the extent that the Grantors' authorization given in Section 3
is not sufficient, to file such financing statements with respect hereto, with
or without the Grantor' signature, as the Agent may deem appropriate and to
execute in the Grantor's name such financing statements and amendments thereto
and continuation statements which may require the Grantor's signature.

     16.2 RATIFICATION BY GRANTORS. To the extent permitted by law, the Grantors
hereby ratify all that said attorney shall lawfully do or cause to be done by
virtue hereof. This power of attorney is a power coupled with an interest and
shall be irrevocable.

                                      D-13

<PAGE>

     16.3 NO DUTY ON PURCHASERS. The powers conferred on the Agent hereunder are
solely to protect its interests in the Collateral and shall not impose any duty
upon it to exercise any such powers. The Agent shall be accountable only for the
amounts that it actually receives as a result of the exercise of such powers and
neither the Agent nor any of its officers, directors, employees or agents shall
be responsible to the Grantor for any act or failure to act, except for the
Agent's own gross negligence or willful misconduct.

     16.4 NO EXERCISE IN ABSENCE OF EVENT OF DEFAULT. The Agent hereby agrees
that it will not exercise any rights conferred by this Section 16 absent the
occurrence of an Event of Default.

17. REMEDIES. Notwithstanding anything to the contrary in this Agreement, upon
the occurrence and during the continuation of an Event of Default, the Agent and
the Holders are limited to the remedies set forth in Section 6 of the Notes,
including those with respect to any First Default, Second Default and Third
Default. Upon the occurrence and during any subsequent Event of Default, the
Agent may, without notice to or demand upon the Grantors, declare this Agreement
to be in default, and the Agent shall thereafter have in any jurisdiction in
which enforcement hereof is sought, in addition to all other rights and
remedies, the rights and remedies of a purchaser under the Uniform Commercial
Code of the State or of any jurisdiction in which Collateral is located,
including, without limitation, the right to take possession of the Collateral,
and for that purpose the Agent may, so far as the Grantors can give authority
therefor, enter upon any premises on which the Collateral may be situated and
remove the same therefrom. The Agent may in its discretion require the Grantors
to assemble all or any part of the Collateral at such location or locations
within the jurisdiction(s) of the Grantors' principal office(s) or at such other
locations as the Agent may reasonably designate. Unless the Collateral is
perishable or threatens to decline speedily in value or is otherwise consented
to by the Grantors, the Agent shall give to the Grantors at least ten Business
Days prior written notice of the time and place of any public sale of Collateral
or of the time after which any private sale or any other intended disposition is
to be made. The Grantors hereby acknowledge that ten Business Days prior written
notice of such sale or sales shall be reasonable notice. In addition, the
Grantors waive any and all rights that it may have to a judicial hearing in
advance of the enforcement of any of the Agent's rights hereunder, including,
without limitation, its right following an Event of Default to take immediate
possession of the Collateral and to exercise its rights with respect thereto.

18. STANDARDS FOR EXERCISING REMEDIES. To the extent that applicable law imposes
duties on the Agent to exercise remedies in a commercially reasonable manner,
the Grantors acknowledge and agree that it is not commercially unreasonable for
the Agent (a) to fail to incur expenses reasonably deemed significant by the
Agent to prepare Collateral for disposition or otherwise to complete raw
material or work in process into finished goods or other finished products for
disposition, in each case after using commercially reasonable efforts, (b) to
fail to obtain third party consents for access to Collateral to be disposed of,
or to obtain or, if not required by other law, to fail to obtain governmental or
third party consents for the collection or disposition of Collateral to be
collected or disposed of, in each case after using commercially reasonable
efforts, (c) to fail to exercise collection remedies against account debtors or
other persons obligated on Collateral or to remove liens or encumbrances on or
any adverse claims against Collateral, (d) to exercise collection remedies
against account debtors and other persons

                                      D-14

<PAGE>

obligated on Collateral directly or through the use of collection agencies and
other collection specialists, (e) to advertise dispositions of Collateral
through publications or media of general circulation, whether or not the
Collateral is of a specialized nature, (f) to contact other persons, whether or
not in the same business as the Grantor, for expressions of interest in
acquiring all or any portion of the Collateral, (g) to hire one or more
professional auctioneers to assist in the disposition of Collateral, whether or
not the collateral is of a specialized nature, (h) to dispose of Collateral by
utilizing Internet sites that provide for the auction of assets of the types
included in the Collateral or that have the reasonable capability of doing so,
or that match buyers and sellers of assets, (i) to dispose of assets in
wholesale rather than retail markets, (j) to disclaim disposition warranties,
(k) to purchase insurance or credit enhancements to insure the Agent's against
risks of loss, collection or disposition of Collateral or to provide to the
Agent a guaranteed return from the collection or disposition of Collateral, or
(1) to the extent deemed appropriate by the Agent, to obtain the services of
other brokers, investment bankers, consultants and other professionals to assist
the Agent in the collection or disposition of any of the Collateral. The
Grantors acknowledge that the purpose of this Section 18 is to provide
non-exhaustive indications of what actions or omissions by the Agent would not
be commercially unreasonable in the Agent's exercise of remedies against the
Collateral and that other actions or omissions by the Agent shall not be deemed
commercially unreasonable solely on account of not being indicated in this
Section 18. Without limitation upon the foregoing, nothing contained in this
Section 18 shall be construed to grant any rights to the Grantors or to impose
any duties on the Agent that would not have been granted or imposed by this
Agreement or by applicable law in the absence of this Section 18.

19. NO ORAL CHANGE; AMENDMENTS; SECURITY AGREEMENT SUPPLEMENTS FOR ADDITIONAL
GRANTORS. No amendment of any provision of this Agreement shall be effective
unless it is in writing and signed by the Grantors, the Agent and the other
Secured Parties, and no waiver of any provision of this Agreement, and no
consent to any departure by the Grantors therefrom, shall be effective unless it
is in writing and signed by the Agent and the Requisite Purchasers, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given. Notwithstanding the foregoing, additional
Persons may become Grantors under this Agreement without consent of any other
Grantor through execution and delivery to the Purchasers of an Assumption
Agreement in the form of Annex 1 hereto or any other form of supplement
acceptable to the Purchasers. Nothing in this Section 19 shall be construed to
permit any Grantor to form a Subsidiary unless expressly permitted to do so
under the Note.

20. SURETYSHIP WAIVERS BY GRANTORS. Each Grantor waives demand, notice, protest,
notice of acceptance of this Agreement, notice of loans made, credit extended,
Collateral received or delivered or other action taken in reliance hereon and
all other demands and notices of any description. With respect to both the
Obligations and the Collateral, the Grantors assent to any extension or
postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of or failure to perfect any security interest
in any Collateral, to the addition or release of any party or person primarily
or secondarily liable, to the acceptance of partial payment thereon and the
settlement, compromising or adjusting of any thereof, all in such manner and at
such time or times as the Agent may deem advisable. The Agent shall have no duty
as to the collection or protection of the Collateral or any income thereon, nor
as to the preservation of rights against prior parties, nor as to the
preservation of any rights pertaining

                                      D-15

<PAGE>

thereto beyond the safe custody thereof as set forth in Section 11.2. The
Grantors further waive any and all other suretyship defenses.

21. MARSHALLING. The Agent shall not be required to marshal any present or
future collateral security (including but not limited to this Agreement and the
Collateral) for, or other assurances of payment of, the Obligations or any of
them or to resort to such collateral security or other assurances of payment in
any particular order, and all of its rights hereunder and in respect of such
collateral security and other assurances of payment shall be cumulative and in
addition to all other rights, however existing or arising. To the extent that it
lawfully may, each Grantors hereby agrees that it will not invoke any law
relating to the marshalling of collateral which might cause delay in or impede
the enforcement of the Agent's rights under this Agreement or under any other
instrument creating or evidencing any of the Obligations or under which any of
the Obligations is outstanding or by which any of the Obligations is secured or
payment thereof is otherwise assured, and, to the extent that it lawfully may,
each Grantor hereby irrevocably waives the benefits of all such laws.

22. PROCEEDS OF DISPOSITIONS; EXPENSES. The Grantors shall pay to the Agent on
demand any and all expenses, including reasonable attorneys' fees and
disbursements, incurred or paid by any Secured Party in protecting, preserving
or enforcing the Agent's or any other Secured Party's rights under or in respect
of any of the Obligations or any of the Collateral. After deducting all of said
expenses, the residue of any proceeds of collection or sale of the Obligations
or Collateral shall, to the extent actually received in cash, be applied to the
payment of the Obligations in such order or preference as the Agent may
reasonably determine, proper allowance and provision being made for any
Obligations not then due. Upon the final payment and satisfaction in full of all
of the Obligations and after making any payments required by Section
9-608(a)(1)(C) or 9-615(a)(3) of the Uniform Commercial Code of the State, any
excess shall be returned to the Grantors, and the Grantors shall remain liable
for any deficiency in the payment of the Obligations.

23. OVERDUE AMOUNTS. Until paid, all amounts due and payable by the Grantors
hereunder shall be a debt secured by the Collateral and shall bear, whether
before or after judgment, interest at the rate of interest set forth in the
Note.

24. GOVERNING LAW; CONSENT TO JURISDICTION.

          (a) Governing Law. This Agreement shall be governed by, and construed
in accordance with, the law of the State (other than those conflict of law rules
that would defer to the substantive laws of another jurisdiction). Without in
any way limiting the preceding choice of law, the parties elect to be governed
by the law of the State in accordance with, and are relying (at least in part)
on, Section 5-1401 of the General Obligations Law of the State, as amended, or
any corresponding or succeeding provisions thereof.

          (b) Submission to Jurisdiction. The Grantors hereby submit to the
exclusive personal jurisdiction of the United States District Court for the
Southern District of New York and of the Supreme Court of the State of New York
sitting in New York County (including its Appellate Division), and of any other
appellate court in the State of New York, for the purposes

                                      D-16

<PAGE>

of all legal proceedings arising out of or relating to this Agreement or the
transactions contemplated hereby.

          (c) Waiver of Venue. The Grantors hereby irrevocably waive, to the
fullest extent permitted by applicable law, any objection that it may now or
hereafter have to the laying of the venue of any such proceeding brought in such
a court and any claim that any such proceeding brought in such a court has been
brought in an inconvenient forum. Without in any way limiting the preceding
consents to personal jurisdiction and venue, the parties agree to submit to the
jurisdiction of the courts of the State of New York in accordance with Section
5-1402 of the General Obligations Law of the State, as amended, or any
corresponding or succeeding provisions thereof.

          (d) Service of Process; Notices. Each party to this Agreement
irrevocably consents to service of process and delivery of notices provided for
hereunder in the manner provided for notices in the Purchase Agreement. Nothing

notices is set forth opposite it signature on its signature page hereto or as
hereafter shall be provided to the Borrower and the Purchasers in writing in the
manner provide for notices in the Purchase Agreement.

25. WAIVER OF JURY TRIAL. THE GRANTORS, THE AGENT AND THE OTHER SECURED PARTIES
HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

26. MISCELLANEOUS; AGREEMENT TO BE BOUND BY PROVISIONS OF TRANSACTION DOCUMENTS
APPLICABLE TO GRANTOR. The headings of each section of this Agreement are for
convenience only and shall not define or limit the provisions thereof. This
Agreement and all rights and obligations hereunder shall be binding upon the
Grantors and their respective successors and assigns, and shall inure to the
benefit of the Secured Parties and their respective successors and assigns. If
any term of this Agreement shall be held to be invalid, illegal or
unenforceable, the validity of all other terms hereof shall in no way be
affected thereby, and this Agreement shall be construed and be enforceable as if
such invalid, illegal or unenforceable term had not been included herein. The
Grantors acknowledge receipt of a copy of this Agreement. Each Grantor agrees to
be bound by each provision of every other Transaction Document which purports to
be applicable to it as if such provision were set forth herein.

27. SUBSIDIARIES.

     27.1 Borrower represents and warrants that each of its Subsidiaries with
assets of $10,000 has entered into this Agreement as a Subsidiary Guarantor.

     27.2 Borrower covenants and agrees that it shall cause each future
Subsidiary that has assets of $10,000 or more to complete, execute and deliver
to the Agent, the form of Assumption Agreement attached as Annex 1 and such
other documents as the Agent shall reasonably request,

                                      D-17

<PAGE>

including, without limitation, evidence of good standing of such Affiliate and
lien searches, all in form and substance acceptable to the Purchasers.

28. LIMITED RECOURSE GUARANTY. Each Subsidiary Guarantor and each other
Subsidiary that becomes a Grantor (each a "Subsidiary Grantor") hereby
unconditionally guarantees the payment when due of all Obligations (the
"Guarantees"), provided, however, that recourse under this provision is limited
to the assets of the Subsidiary Grantor that are, or will be, included as part
of the Collateral. The Guarantees are irrevocable and will not be affected by
any release of any Grantor or surrender, exchange, compromise or release any
Collateral, by any failure to perfect any liens, by any irregularity,
enforceability or invalidity of any Obligations or any part thereof or any
security or guaranty thereof. Each Subsidiary Grantor waives all defenses based
on suretyship or on impairment of Collateral. Without notice to, or the consent
of, any Subsidiary Grantor, the terms of the Obligations and any related
documents may be changed, extended, renewed or compromised.

29. FURTHER ASSURANCES. Borrower and each Subsidiary Grantor shall execute and
deliver all such further instruments and documents and take all such other
actions as may reasonably be required to carry out the transactions contemplated
hereby and to evidence the fulfillment of the agreements herein contained.

30. COLLATERAL AGENCY.

     30.1 APPOINTMENT OF AGENT. Each Purchaser hereby appoints Agent to serve as
collateral agent hereunder and each Purchaser hereby authorizes Agent, in such
capacity, to act as its agent and representative hereunder in accordance with
the terms hereof and with respect to the Guarantees, the Collateral and the
other Security Documents. The provisions of this Section 30 are solely for the
benefit of the Agent and Purchasers and none of the Grantors shall have any
rights as a third party beneficiary of any of the provisions of this Section 30;
provided, however, that the Grantors shall be entitled to rely on consents and
approvals executed by the Agent without investigation as to the existence of
proper authorization by the other Secured Parties. In performing its functions
and duties hereunder, the Agent shall act solely as an agent of the Purchasers
and does not assume and shall not be deemed to have assumed any obligation
towards or relationship of agency or trust with or for any of the Grantors or
any Subsidiary or Affiliate thereof.

     30.2 POWERS AND DUTIES. Each Purchaser irrevocably authorizes the Agent to
take such action on such Purchaser's behalf and to exercise such powers, rights
and remedies hereunder as are specifically delegated or granted to the Agent by
the terms hereof, together with such powers, rights and remedies as are
reasonably incidental thereto. The Agent shall have only those duties and
responsibilities that are expressly specified herein. The Agent may exercise
such powers, rights and remedies and perform such duties by or through its
agents or employees. The Agent shall not have, by reason hereof or of any other
Transaction Document, a fiduciary relationship in respect of any Purchaser; and
nothing herein, expressed or implied, is intended to or shall be so construed as
to impose upon the Agent any obligations in respect hereof or any of the other
Transaction Documents except as expressly set forth herein.

                                      D-18

<PAGE>

     30.3 GENERAL IMMUNITY.

          (a) No Responsibility for Certain Matters. The Agent shall not be
responsible to any Purchaser for the execution, effectiveness, genuineness,
validity, enforceability, collectability or sufficiency hereof or any other
Transaction Document or for any representations, warranties, recitals or
statements made herein or therein or made in any written or oral statements or
in any other statements, instruments, reports or certificates or any other
documents furnished or made by the Agent to Purchasers or by or on behalf of any
Grantor to the Agent or any other Secured Party in connection with this
Agreement or any other Transaction Document and the transactions contemplated
hereby or thereby or for the financial condition or business affairs of any
Grantor or the condition of any of the Collateral, nor shall the Agent be
required to ascertain or inquire as to the performance or observance of any of
the terms, conditions, provisions, covenants or agreements contained in this
Agreement or any of the other Transaction Documents or as to the existence or
possible existence of any Event of Default or Default or to make any disclosures
with respect to the foregoing.

          (b) Exculpatory Provisions. Neither the Agent, nor any Affiliate of
the Agent, nor any of their respective officers, partners, directors, employees,
controlling persons, auditors or agents shall be liable to Purchasers for any
action taken or omitted by the Agent hereunder or in connection with any of the
other Transaction Documents except to the extent found by a final,
non-appealable judgment of a court of competent jurisdiction to have been caused
by the Agent's gross negligence or willful misconduct. The Agent shall be
entitled to refrain from any act or the taking of any action (including the
failure to take an action) in connection herewith or any of the other
Transaction Documents or from the exercise of any power, discretion or authority
vested in it hereunder or thereunder unless and until the Agent shall have
received instructions in respect thereof from Purchasers holding a majority in
principal amount of the Notes then outstanding (the "Requisite Purchasers") and,
upon receipt of such instructions from Requisite Purchasers, the Agent shall be
entitled to act or (where so instructed) refrain from acting, or to exercise
such power, discretion or authority, in accordance with such instructions.
Without prejudice to the generality of the foregoing, (i) the Agent shall be
entitled to rely, and shall be fully protected in relying, upon any
communication, instrument or document believed by it to be genuine and correct
and to have been signed or sent by the proper Person or Persons, and shall be
entitled to rely and shall be protected in relying on opinions and judgments of
attorneys (who may be attorneys for the Grantors), accountants, experts and
other professional advisors selected by it; and (ii) no Purchaser shall have any
right of action whatsoever against the Agent as a result of the Agent acting or
(where so instructed) refraining from acting hereunder or under any of the other
Transaction Documents in accordance with the instructions of Requisite
Purchasers.

     30.4 AGENT ENTITLED TO ACT AS PURCHASER. The agency hereby created shall in
no way impair or affect any of the rights and powers of, or impose any duties or
obligations upon, the Agent in its individual capacity as a Purchaser hereunder.
With respect to its holding of Notes, the Agent shall have the same rights and
powers hereunder as any other Purchaser and may exercise the same as if it were
not performing the duties and functions delegated to it hereunder, and the term
"Purchaser" shall, unless the context clearly otherwise indicates, include the
Agent in its individual capacity. The Agent and its Affiliates may accept
deposits from, lend money to, own securities of, and generally engage in any
kind of banking, trust, financial advisory or other business with any Grantor or
any of their Affiliates as if it were not performing the duties

                                      D-19

<PAGE>

specified herein, and may accept fees and other consideration from Borrower for
services in connection herewith and otherwise without having to account for the
same to Purchasers.

     30.5 PURCHASERS' REPRESENTATIONS, WARRANTIES AND ACKNOWLEDGMENT.

          (a) Each Purchaser represents and warrants that it has made its own
independent investigation of the financial condition and affairs of the Grantors
and the condition and value of the Collateral in connection with its purchase of
Notes. The Agent shall not have any duty or responsibility, either initially or
on a continuing basis, to make any investigation or appraisal of the
creditworthiness of the Grantors or the condition and value of the Collateral on
behalf of the Purchasers or to provide any Purchaser with any information with
respect thereto, and the Agent shall not have any responsibility with respect to
the accuracy of or the completeness of any information provided to the
Purchasers.

          (b) Each Purchaser, by delivering its signature page to this Agreement
and funding its Notes shall be deemed to have acknowledged receipt of, and
consented to and approved, this Agreement, each other Transaction Document and
each other document required to be approved by the Agent, Requisite Purchasers
or Purchasers, as applicable on the date hereof.

     30.6 RIGHT TO INDEMNITY. Each Purchaser, in proportion to the pro rata
share of the principal amount of Notes purchased by it on the date hereof ("Pro
Rata Share"), severally agrees to indemnify the Agent, its Affiliates and their
respective officers, partners, directors, trustees, employees, auditors,
controlling persons and agents (each, an "Indemnitee Agent Party"), to the
extent that such Indemnitee Agent Party shall not have been reimbursed by any
Grantor, for and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including counsel fees
and disbursements) or disbursements of any kind or nature whatsoever which may
be imposed on, incurred by or asserted against such Indemnitee Agent Party in
exercising its powers, rights and remedies or performing its duties hereunder or
under the other Transaction Documents or otherwise in its capacity as such
Indemnitee Agent Party in any way relating to or arising out of this Agreement
or the other Transaction Documents, IN ALL CASES, WHETHER OR NOT CAUSED BY OR
ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE, CONTRIBUTORY, OR SOLE
NEGLIGENCE OF SUCH INDEMNITEE AGENT PARTY; provided, that no Purchaser shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from such Indemnitee Agent Party's gross negligence or willful misconduct to the
extent that such have been found by a final, non-appealable judgment of a court
of competent jurisdiction. If any indemnity furnished to any Indemnitee Agent
Party for any purpose shall, in the opinion of such Indemnitee Agent Party, be
insufficient or become impaired, such Indemnitee Agent Party may call for
additional indemnity and cease, or not commence, to do the acts indemnified
against unless and until such additional indemnity is furnished; provided, that
in no event shall this sentence require any Purchaser to indemnify any
Indemnitee Agent Party against any liability, obligation, loss, damage, penalty,
action, judgment, suit, cost, expense or disbursement in excess of such
Purchaser's Pro Rata Share thereof; and provided, further, that this sentence
shall not be deemed to require any Purchaser to indemnify any Indemnitee Agent
Party against any liability, obligation, loss,

                                      D-20

<PAGE>

damage, penalty, action, judgment, suit, cost, expense or disbursement described
in the proviso in the immediately preceding sentence.

     30.7 SUCCESSOR AGENT.

          (a) The Agent may resign at any time by giving fifteen (15) Business
Days' prior written notice thereof to Purchasers and Borrower, which resignation
shall be effective as to this Agreement and each other Security Document for
which Agent acts in its capacity as such. Upon any such notice of resignation,
the Requisite Purchasers shall have the right, upon five Business Days' notice
to Borrower, to appoint a successor Agent. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, that successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent and the Agent shall promptly (i) transfer to
such successor Agent all sums, Securities and other items of Collateral and the
other Security Documents creating a security interest in any of the Collateral,
together with all records and other documents necessary or appropriate in
connection with the performance of the duties of the successor Agent under this
Agreement and the other Transaction Documents, and (ii) execute and deliver to
such successor Agent such amendments to financing statements, and take such
other actions, as may be necessary or appropriate in connection with the
assignment to such successor Agent of the security interests created under the
Security Documents, whereupon such retiring Agent shall be discharged from its
duties and obligations hereunder. After any retiring Agent's resignation
hereunder as Agent, the provisions of this Section 30 shall inure to its benefit
as to any actions taken or omitted to be taken by it while it was Agent
hereunder.

          (b) Notwithstanding anything herein to the contrary, the Agent may
assign its rights and duties as Agent hereunder to any of its Affiliates (other
than any Grantor or any Subsidiary thereof) without the prior written consent
of, or prior written notice to, the Grantors or the Purchasers under this
Agreement and any other Security Document for which Agent acts in its capacity
as such; provided that the Grantors and the Purchasers may deem and treat such
assigning Agent as the Agent for all purposes hereof, unless and until such
assigning Agent provides written notice to Borrower and the Purchasers of such
assignment. Upon such assignment such Affiliate shall succeed to and become
vested with all rights, powers, privileges and duties as Agent hereunder and
under the other Transaction Documents.

     30.8 COLLATERAL AND GUARANTEES.

          (a) Right to Release Collateral or Guarantees. Subject to Section 19,
without further written consent or authorization from the Purchasers, the Agent
may execute any documents or instruments necessary to (i) release any lien
encumbering any item of Collateral that is the subject of a sale or other
disposition of assets permitted under the terms of Transaction Documents or to
which Requisite Purchasers have otherwise consented, or (ii) release any
Subsidiary Grantor from its Guarantee upon the sale of such Subsidiary as
permitted pursuant to the terms and conditions of the Transaction Documents or
to which Requisite Purchasers have otherwise consented.

                                      D-21

<PAGE>

          (b) Right to Realize on Collateral and Enforce Guarantees. Anything
contained in any of the Transaction Documents to the contrary notwithstanding,
the Grantors, the Agent and each Purchaser hereby agree that (i) no Purchaser
shall have any right individually to realize upon any of the Collateral or to
enforce any of the Guarantees, it being understood and agreed that all powers,
rights and remedies hereunder may be exercised solely by the Agent, on behalf of
Purchasers in accordance with the terms hereof and all powers, rights and
remedies under the other Security Documents may be exercised solely by the
Agent, and (ii) in the event of a foreclosure by the Agent on any of the
Collateral pursuant to a public or private sale, the Agent or any other Secured
Party may be the purchaser of any or all of such Collateral at any such sale and
the Agent, as agent for and representative of Secured Parties (but not any
Purchaser or Purchasers in its or their respective individual capacities unless
Requisite Purchasers shall otherwise agree in writing) shall be entitled, for
the purpose of bidding and making settlement or payment of the purchase price
for all or any portion of the Collateral sold at any such public sale, to use
and apply any of the Obligations as a credit on account of the purchase price
for any collateral payable by the Agent at such sale.

31. TERMINATION. This Agreement shall remain in full force and effect until such
time as all principal and any accrued interest on the Notes is either (a)
converted into Common Stock in accordance with the terms of the Notes or (b)
indefeasibly paid in full and, in the case of either (a) or (b), all other
Obligations then due and owing (including Post-Petition Interest) are
indefeasibly paid in full; provided, however, that, so long as no Event of
Default, or event which, with the giving of notice, the lapse of time for both
would constitute an Event of Default, has occurred and is continuing, the Agent,
upon the written request of a Grantor, shall release and otherwise terminate any
and all Liens and security interests held by Agent with respect to (a) such
Grantor's accounts and such Grantor's inventory in the event that (i) such
Grantor obtains the Future Working Capital Line (as defined in the Note) and
(ii) the release and termination of such Liens and security interests are
necessary for such Grantor to obtain the Future Working Capital Line and (b)
such Grantor's right, title and interest in and to the assets of the Peridex(R)
product line effective upon the consummation of the sale of the Peridex(R)
product line on the terms and conditions approved by such Grantor's board of
directors. Following the termination hereof, upon the request of and at the
expense of the Grantors, the Agent shall reassign to the Grantors all Collateral
held by Agent and shall execute a termination of all security agreements and
security interests given by Grantors to Agent.

                        SUPPLEMENT TO SECURITY AGREEMENT.

     This Agreement has been entered into in conjunction with the security
interests granted to the Agent under the Security Agreement, and other security
documents referred to therein. The rights and remedies of the Agent and the
other Secured Parties with respect to the security interests granted herein are
without prejudice to, and are in addition to those set forth in the Security
Agreement or any other security documents referred to therein, all terms and
provisions of which are incorporated herein by reference.

                                   SECTION 4.

                         REPRESENTATIONS AND WARRANTIES.

     Each Grantor represents and warrants to the Agent and the other Secured
Parties that:

     (a) Copyright Registrations. A true and correct list of all of such
Grantor's United States registered copyrights and copyright registrations is set
forth in Schedule A.

     (b) Applications for Copyright Registration. A true and correct list of all
of such Grantor's United States applications for copyright registrations is set
forth in Schedule B.

                                   SECTION 5.

                                  FURTHER ACTS.

     On a continuing basis, each Grantor shall make, execute, acknowledge and
deliver, and file and record in the proper filing and recording places, all such
instruments and documents, and take all such action as may be reasonably
necessary or advisable or may be reasonably requested by the Agent or any other
Secured Party to carry out the intent and purposes of this Agreement, or for
assuring, confirming or protecting the grant or perfection of the first priority
security interest granted or purported to be granted hereby, to ensure such
Grantor's compliance with this Agreement or to enable the Agent to exercise and
enforce the rights and remedies of the Agent and the other Secured Parties
hereunder with respect to the Collateral, including any documents for filing
with the Copyright Office or any applicable state office. The Agent may record
this Agreement, an abstract thereof, or any other document describing the
Agent's interest in the

3

<PAGE>

Copyrights with the Copyright Office, at the expense of such Grantor. In
addition, each Grantor authorizes the Agent to file financing statements
describing the Collateral in any UCC filing office deemed appropriate by the
Agent. If any Grantor shall at any time hold or acquire a commercial tort claim
arising with respect to the Collateral, such Grantor shall immediately notify
the Agent and the other Secured Parties in a writing signed by such Grantor of
the brief details thereof and grant to the Agent (on behalf of the Secured
Parties) in such writing a security interest therein and in the proceeds
thereof, all upon the terms of this Agreement, with such writing to be in form
and substance satisfactory to the Agent and the Requisite Purchasers.

                                   SECTION 6.

                          AUTHORIZATION TO SUPPLEMENT.

     Each Grantor shall give the Agent and the other Secured Parties prompt
notice of any additional United States copyright registrations or applications
therefor after the date hereof. Each Grantor authorizes the Agent unilaterally
to modify this Agreement by amending Schedule A or B to include any future
United States registered copyrights or applications therefor of such Grantor.
Notwithstanding the foregoing, no failure to so modify this Agreement or amend
Schedule A or B shall in any way affect, invalidate or detract from Agent's
continuing security interest in all Collateral, whether or not listed on
Schedule A or B.

                                   SECTION 7.

                                 BINDING EFFECT.

     This Agreement shall be binding upon, inure to the benefit of and be
enforceable by each Grantor, the Agent and the other Secured Parties and their
respective successors and assigns. Except as provided in Section 30.7 of the
Security Agreement, no party hereto may assign, transfer, hypothecate or
otherwise convey its rights, benefits, obligations or duties hereunder except as
agreed to in writing by the other parties hereto.

                                   SECTION 8.

                                 GOVERNING LAW.

     This Agreement shall be governed by, and construed in accordance with, the
law of the State of New York, except as required by mandatory provisions of law
or to the extent the perfection or priority of the security interests hereunder,
or the remedies hereunder, in respect of any Collateral are governed by the law
of a jurisdiction other than the State of New York.

     No amendment of any provision of this Agreement shall be effective unless
it is in writing and signed by the Grantors, the Agent and the Requisite
Purchasers, and no waiver of any provision of this Agreement, and no consent to
any departure by the Grantors therefrom, shall be effective unless it is in
writing and signed by the Agent and

4

<PAGE>

consented to in writing by the Requisite Purchasers, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given. Notwithstanding the foregoing, (i) additional Persons
may become Grantors under this Agreement without consent of any other Grantor
through execution and delivery to the Agent of an Assumption Agreement in the
form of Annex 1 hereto or any other form of supplement acceptable to the Agent,
and (ii) the Agent unilaterally may re-execute this Agreement or modify, amend
or supplement the Schedules hereto as provided in Section 6 hereof. To the
extent that any provision of this Agreement conflicts with any provision of the
Notes, the provision giving the Secured Parties greater rights or remedies shall
govern, it being understood that the purpose of this Agreement is to add to, and
not detract from, the rights granted to Purchasers under the Notes. Nothing in
this Section 9 shall be construed to permit any Grantor to form a Subsidiary
unless expressly permitted to do so under the Notes.

                                   SECTION 10.

                                  COUNTERPARTS.

     This Agreement may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall
constitute but one and the same agreement. Delivery of an executed counterpart
of this Agreement by facsimile shall be equally as effective as delivery of a
manually executed counterpart. Any party hereto delivering a counterpart of this
Agreement by facsimile shall also deliver a manually executed counterpart, but
the failure to so deliver a manually executed counterpart shall not affect the
validity, enforceability, or binding effect hereof.

                                   SECTION 11.

                                  TERMINATION.

     Upon the indefeasible payment and performance in full of all Obligations,
the security interests created by this Agreement shall terminate and the Agent
(at the Grantors' expense) shall promptly execute and deliver to the Grantors
such documents and instruments reasonably requested by the Grantors as shall be
necessary to evidence termination of all such security interests given by the
Grantors to Agent hereunder, including cancellation of this Agreement by written
notice from Agent to the Copyright Office.

                                   SECTION 12.

                          NO INCONSISTENT REQUIREMENTS.

     Each Grantor acknowledges that this Agreement and the other documents,
agreements and instruments entered into or executed in connection herewith may
contain covenants and other terms and provisions variously stated regarding the
same or similar matters, and each Grantor agrees that all such covenants, terms
and provisions are

5

<PAGE>

cumulative and all shall be performed and satisfied in accordance with their
respective terms.

                                   SECTION 13.

                                  SEVERABILITY.

     If one or more provisions contained in this Agreement shall be invalid,
illegal or unenforceable in any respect in any jurisdiction or with respect to
any party, such invalidity, illegality or unenforceability in such jurisdiction
or with respect to such party shall, to the fullest extent permitted by
applicable law, not invalidate or render illegal or unenforceable any such
provision in any other jurisdiction or with respect to any other party, or any
other provisions of this Agreement.

                                   SECTION 14.

                                    NOTICES.

     All notices and other communications hereunder shall be in writing and
shall be mailed, sent or delivered in accordance with the Purchase Agreement and
the Security Agreement.

by the Agent of the Trademarks after the occurrence and during the continuance
of an Event of Default shall be worldwide, except as limited by their terms, and
without any liability for royalties or related charges from the Agent to
Grantor.

     This Agreement shall be governed by, and construed in accordance with, the
law of the State of New York, except as required by mandatory provisions of law
or to the extent the perfection or priority of the security interests hereunder,
or the remedies hereunder, in respect of any Collateral are governed by the law
of a jurisdiction other than the State of New York.

                           ENTIRE AGREEMENT; AMENDMENT

     No amendment of any provision of this Agreement shall be effective unless
it is in writing and signed by the Grantors, the Agent and the Requisite
Purchasers, and no waiver of any provision of this Agreement, and no consent to
any departure by the Grantors therefrom, shall be effective unless it is in
writing and signed by the Agent and consented to in writing by the Requisite
Purchasers, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given. Notwithstanding
the foregoing, (a) additional Persons may become Grantors under this Agreement
without consent of any other Grantor through execution and delivery to the Agent
of an Assumption Agreement in the form of Annex 1 hereto or any other form of
supplement acceptable to the Agent, and (b) the Agent unilaterally may modify,
amend or supplement the Schedules hereto, and such modified, amended or
supplemented Schedules shall be deemed to be accurate absent manifest error. To

to, and not detract from, the rights granted to Purchasers under the Notes.

     This Agreement may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall
constitute but one and the same agreement. Delivery of an executed counterpart
of this Agreement by facsimile shall be equally as effective as delivery of a
manually executed counterpart. Any party hereto delivering a counterpart of this
Agreement by facsimile shall also deliver a manually executed counterpart, but
the failure to so deliver a manually executed counterpart shall not affect the
validity, enforceability, or binding effect hereof.

                                   SECTION 12.

                                   TERMINATION

     Upon the indefeasible payment and performance in full of all Obligations,
the security interests created by this Agreement shall terminate and the Agent
(at the Grantors' expense) shall promptly execute and deliver to the Grantors
such documents and instruments reasonably requested by the Grantors as shall be
reasonably necessary to evidence termination of all such security interests
given by the Grantors to the Agent hereunder, including cancellation of this
Agreement by written notice from the Agent to the Trademark Office.

agreements and instruments entered into or executed in connection herewith may
contain covenants and other terms and provisions variously stated regarding the
same or similar matters, and each Grantor agrees that all such covenants, terms
and provisions are cumulative and all shall be performed and satisfied in
accordance with their respective terms.

                                  SEVERABILITY

     If one or more provisions contained in this Agreement shall be invalid,
illegal or unenforceable in any respect in any jurisdiction or with respect to
any party, such invalidity, illegality or unenforceability in such jurisdiction
or with respect to such party

                        SUPPLEMENT TO SECURITY AGREEMENT.

          This Agreement has been entered into in conjunction with the
continuing first priority security interests granted to the Agent under the
Security Agreement, and other security documents referred to therein. The rights
and remedies of the Agent and the other Secured Parties with respect to the

referred to therein, all terms and provisions of which are incorporated herein
by reference.

                                   SECTION 4.

                         REPRESENTATIONS AND WARRANTIES.

     Each Grantor represents and warrants to Secured Parties that:

          (a) Patent Registrations. A true and correct list of all of such
Grantor's Patents is set forth on Schedule A.

          (b) Applications for Patents. A true and correct list of all of such
Grantor's applications for Patents is set forth on Schedule B.

                                   SECTION 5.

                                  FURTHER ACTS.

     On a continuing basis, each Grantor shall make, execute, acknowledge and
deliver, and file and record in the proper filing and recording places, all such
instruments and documents, and take all such action as may be reasonably
necessary or advisable or may be reasonably requested by the Agent to carry out
the intent and purposes of this Agreement, or for assuring, confirming or
protecting the grant or perfection of the continuing first priority security
interest granted or purported to be granted hereby, to ensure such Grantor's
compliance with this Agreement or to enable the Agent to exercise and enforce
the rights and remedies of the Agent and the other Secured Parties hereunder
with respect to the Collateral, including any documents for filing with the
Patent Office or any applicable state office. The Agent may record this
Agreement, an abstract thereof, or any other document describing the Agent's
interest in the Patents with the Patent Office, at the expense of such Grantor.
In addition, each Grantor authorizes the Agent to file financing statements
describing the Collateral in any UCC filing office deemed appropriate by the
Agent. If any Grantor shall at any time hold or acquire a commercial tort claim
arising with respect to the Collateral, such Grantor shall immediately notify
the Agent and the other Secured Parties in a writing signed by such Grantor of
the brief details thereof and grant to the Agent (on behalf of the Secured
Parties) in such writing a security interest therein and in the proceeds
thereof, all upon the terms of this Agreement, with such writing to be in form
and substance satisfactory to the Agent and the Requisite Purchasers.

                          AUTHORIZATION TO SUPPLEMENT.

     Each Grantor shall give the Agent and the other Secured Parties prompt
notice of any additional United States Patent registrations or applications
therefor after the date hereof. Each Grantor authorizes the Agent unilaterally
to modify this Agreement by amending Schedule A or B to include any future
United States registered Patents or applications therefor of such Grantor.
Notwithstanding the foregoing, no failure to so modify this Agreement or amend
Schedule A or B shall in any way affect, invalidate or detract from Agent's
continuing security interest in all Collateral, whether or not listed on
Schedule A or B.

                                   SECTION 7.

                                 BINDING EFFECT.

     This Agreement shall be binding upon, inure to the benefit of and be
enforceable by each Grantor, the Agent and the other Secured Parties and their
respective successors and assigns. Except as provided in Section 30.7 of the
Security Agreement, no party hereto may assign, transfer, hypothecate or
otherwise convey its rights, benefits, obligations or duties hereunder except as
agreed to in writing by the other parties hereto.

                                   SECTION 8.

                                 GOVERNING LAW.

     This Agreement shall be governed by, and construed in accordance with, the
law of the State of New York, except as required by mandatory provisions of law
or to the extent the perfection or priority of the security interests hereunder,
or the remedies hereunder, in respect of any Collateral are governed by the law
of a jurisdiction other than the State of New York.

                                   SECTION 9.

                          ENTIRE AGREEMENT; AMENDMENT.

     No amendment of any provision of this Agreement shall be effective unless
it is in writing and signed by the Grantors, the Agent and the Requisite
Purchasers, and no waiver of any provision of this Agreement, and no consent to
any departure by the Grantors therefrom, shall be effective unless it is in
writing and signed by the Agent and consented to in writing by the Requisite
Purchasers, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given. Notwithstanding
the foregoing, (i) additional Persons may become Grantors under this Agreement
without consent of any other Grantor through execution and delivery to the Agent
of an Assumption Agreement in the form of Annex 1 hereto or any other form of
supplement acceptable to the Agent, and (ii) the Agent unilaterally may
re-execute this Agreement, to the extent reasonably necessary, to modify, amend
or supplement Schedule A or B hereto as provided in Section 6 hereof, and such
modified, amended or supplemented Schedules shall be deemed to be accurate
absent manifest error. To the extent that any provision of this Agreement
conflicts with any provision of the

<PAGE>

Notes, the provision giving the Secured Parties greater rights or remedies shall
govern, it being understood that the purpose of this Agreement is to add to, and
not detract from, the rights granted to Purchasers under the Notes. Nothing in
this Section 9 shall be construed to permit any Grantor to form a Subsidiary
unless expressly permitted to do so under the Notes.

                                   SECTION 10.

                                  COUNTERPARTS.

     This Agreement may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall
constitute but one and the same agreement. Delivery of an executed counterpart
of this Agreement by facsimile shall be equally as effective as delivery of a
manually executed counterpart. Any party hereto delivering a counterpart of this
Agreement by facsimile shall also deliver a manually executed counterpart, but
the failure to so deliver a manually executed counterpart shall not affect the
validity, enforceability, or binding effect hereof.

                                   SECTION 11.

                                  TERMINATION.

     Upon the indefeasible payment and performance in full of all Obligations,
the security interests created by this Agreement shall terminate and the Agent
(at the Grantors' expense) shall promptly execute and deliver to the Grantors
such documents and instruments reasonably requested by the Grantors as shall be
necessary to evidence termination of all such security interests given by the
Grantors to the Agent hereunder, including cancellation of this Agreement by
written notice from Purchasers to the Patent Office.

                                   SECTION 12.

                          NO INCONSISTENT REQUIREMENTS.

     Each Grantor acknowledges that this Agreement and the other documents,
agreements and instruments entered into or executed in connection herewith may
contain covenants and other terms and provisions variously stated regarding the
same or similar matters, and each Grantor agrees that all such covenants, terms
and provisions are cumulative and all shall be performed and satisfied in
accordance with their respective terms.

                                   SECTION 13.

                                  SEVERABILITY.

     If one or more provisions contained in this Agreement shall be invalid,
illegal or unenforceable in any respect in any jurisdiction or with respect to
any party, such invalidity, illegality or unenforceability in such jurisdiction
or with respect to such party shall, to the fullest extent permitted by
applicable law, not invalidate or render illegal or unenforceable any such

provision in any other jurisdiction or with respect to any other party, or any

Attention: Michael Vermut

Dear Mike:

     Reference is hereby made to the Purchase Agreement, dated as of November
___, 2006 (the "Purchase Agreement"), by and among Zila, Inc. (the "Company")
and the investors party thereto (the "Investors"). Capitalized terms used herein
have the respective meanings ascribed thereto in the Purchase Agreement unless
otherwise defined herein.

     In order to induce the Investors to purchase the Notes and the Warrants,
the Company hereby agrees as follows:

     1. The Company agrees to the following corporate governance changes as
being in the best interests of the Company and its stockholders, including the
Investors:

          (a) The functions of the Chief Executive Officer and Chairman of the
Board shall be separated so that such positions are not held by the same person;

          (b) No later than the close of business on August 1, 2007 (the
"Outside Date"), the Board shall appoint a Chairman or Chairwoman of the Board
who shall not be the same person as the Chief Executive Officer and who shall be
selected pursuant to the Company's existing Board development plan, a copy of
which has previously been provided to the Investors (the "Plan"), and, to the
extent not inconsistent therewith, the process specified in paragraph (d) below;

          (c) No later than the close of business on the Outside Date, the Board
shall increase the number of persons constituting the Board by two (in addition
to the directors to be elected at the annual meeting to be held on December 14,
2006) and shall use its commercially reasonable efforts to fill the vacancies
resulting from the creation of such vacancies (the "Additional Directors")
pursuant to the Plan, the Director Nomination Process, a copy of which has been
provided to the Investors ("the Process"), and, to the extent not inconsistent
therewith, the process specified in paragraph (d) below;

          (d) Promptly following the date hereof, the Investors or their
designee will provide the Nominations and Corporate Governance Committee of the
Board (the "Committee") with a list of prospective candidates for membership on
the Board. Such list shall be comprised of persons of high quality suitable for
membership on the board of directors of a publicly traded

<PAGE>

company and each of such persons shall meet the criteria set forth in the Plan
and, to the extent not inconsistent therewith, the following criteria:

               (i) such person shall have significant experience as a member of
senior management or the board of directors of a successful life sciences
company;

               (ii) such person shall have professional and educational
qualifications appropriate for membership on the Board and shall have the time
necessary to devote to Board membership;

               (iii) such person shall have familiarized himself or herself with
the operations and future prospects of the Company and its Subsidiaries;

               (iv) such person shall not be subject to any fine, judgment,
injunction or other proceeding required to be disclosed pursuant to Item 103 of
Regulation S-K; and

               (v) such person shall qualify as an "independent" director of the
Company under applicable SEC and Nasdaq rules and regulations.

     The Committee shall evaluate and consider in good faith as contemplated by
the Plan and the Process the prospective candidates recommended by the
Investors. The Committee may, consistent with the Plan and the Process, also
consider such additional persons as may be recommended for membership on the
Board by stockholders or other third parties; provided the Board or the
Committee reasonably determines that such additional persons meet the criteria
set forth in the Plan and the Process and, to the extent not inconsistent
therewith, those set forth above. In performing its evaluation and
consideration, the Committee shall, among other things, perform appropriate
background and reference checks and shall solicit and consider in good faith the
views of the Investors. If requested, the Investors shall have the right to meet
any final candidates prior to their selection. Upon request, the Committee, or
its designee, shall inform the Investors as to the progress of the Committee's
activities; provided, however, that no material nonpublic information shall be
provided to the Investors.

     Upon completion of its evaluation and consideration, the Committee shall
make its recommendations to the Board in accordance with the Plan and the
Process. Promptly thereafter, the Board shall take such action as may be
necessary or advisable to appoint the Chairman of the Board and the Additional
Directors; provided, however, that if the Board determines, in the good faith
application of its reasonable business judgment, that only one person is
qualified to be an Additional Director or if only one person accepts an
invitation to become an Additional Director, the Board shall instruct the
Committee to, and the Committee shall, continue to pursue the appointment of a
second Additional Director in good faith.

     2. The Company acknowledges and agrees that the failure of the Company to
comply with the provisions of this letter shall constitute an Event of Default
(as such term is defined in the Notes). Time shall be of the essence in the
performance of the obligations contained herein.

                                       E-2

          SECTION 2.05. Directors and Officers. The directors of Merger Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Articles of
Incorporation and By-laws of the Surviving Corporation, and the officers of

of the Surviving Corporation, in each case until their respective successors are
duly elected or appointed and qualified or until the earlier of their death,

          SECTION 2.06. Effect on Capital Stock At the Effective Time, by virtue
of the Merger and without any action on the part of the holder of any shares of
Common Stock or any capital stock of Parent or shares of capital stock of Merger
Sub:

          (a) Capital Stock of Merger Sub. Each issued and outstanding share of
     capital stock of Merger Sub shall be converted into and become one validly
     issued, fully paid and nonassessable share of common stock, par value $0.01
     per share, of the Surviving Corporation.

          (b) Cancellation of Treasury Stock and Company-Owned Stock. Each share
     of Common Stock that is directly owned by the Company or any Subsidiary
     immediately prior to the Effective Time shall automatically be cancelled
     and retired and shall cease to exist, and no consideration shall be
     delivered in exchange therefore.

          (c) Conversion of Company Common Stock. Subject to Section 2.08(e),
     each share of Common Stock of the Company issued and outstanding
     immediately prior to the Effective Time (other than shares to be cancelled
     in accordance with Section 2.06(b) or the Dissenting Shares (as defined
     below)) shall be converted into the right to receive, as and when set forth
     in this Agreement and the Escrow Agreement (as applicable), an amount equal
     to:

               (i) $26,064.03 in cash, without interest (the aggregate amount so
          payable by Parent being referred to as the "Merger Consideration"),
          less

               (ii) a per-share portion of the Escrow Amount, (the Merger
          Consideration less the Escrow Amount being referred to as the "Closing
          Merger Consideration"), plus

               (iii) a per-share portion of any amount remaining in the Escrow
          Account after all required distributions have been made pursuant to
          the Escrow Agreement and the terms hereof (the aggregate amount so
          distributable being referred to as the "Escrow Distribution").

          (d) At the Effective Time, all such shares of Common Stock shall no
     longer be outstanding and shall automatically be cancelled and retired and

<PAGE>

     and each Stockholder (or any holder of a Certificate (as defined below)
     which immediately prior to the Effective Time represented any such shares
     of Common Stock) shall cease to have any rights with respect thereto,
     except the right to receive his, her or its respective portions of the
     Closing Merger Consideration and the Escrow Distribution, if any. The right
     of any Stockholder to receive his, her or its respective portions of the
     Closing Merger Consideration and the Escrow Distribution, if any, shall be
     subject to and reduced by the amount of any withholding that is required
     under applicable tax law.

          (e) Other Company Capital Stock. Each share of capital stock of the
     Company (other than Common Stock) issued and outstanding prior to the
     Effective Time shall automatically be canceled and retired, shall cease to
     exist and shall no longer be outstanding and the holder of any certificate
     or other evidence of ownership that prior to the Effective Time represented
     such shares of capital stock shall cease to have any rights with respect
     thereto and shall have no right to receive any portion of the Merger
     Consideration by reason thereof.

          SECTION 2.07. Escrow Account. At the Closing, Parent will deposit with
J.P. Morgan Trust Company, National Association, a portion of the Merger
Consideration (the "Escrow Amount") equal to:

          (a) $600,000, as a reserve against liabilities of the Company
     identified in an audit by the IRS of the Company's filing for
     extraterritorial income benefit in fiscal years 2003, 2004 and 2005, plus

          (b) an amount (not to exceed $750,000), to be agreed upon by Parent
     and the Principal Stockholders, sufficient to pay the premium of the R&W
     Insurance Policy, plus

          (c) an amount equal to the sum of (A) an amount, to be determined by
     the Company, sufficient to pay all income Taxes (if any) reasonably
     expected by the Company to be due and payable after the Closing Date with
     respect to all taxable periods ending on or before the Closing Date and, to
     the extent applicable, any Pre-Closing Tax Period, and all Taxes (if any )
     reasonably expected by the Company to result from the Pre Effective Carve
     out Transactions, (B) an amount, to be agreed upon by the Parent and the
     Principal Stockholders, sufficient to pay any unpaid costs and expenses,
     including fees and disbursements of counsel, financial advisors and
     accountants, reasonably expected to be incurred by the Company in
     connection with this Agreement and the transactions contemplated by this
     Agreement, including the Pre-Effective Carve-Out Transactions, and (C) an
     amount, to be agreed upon by the Parent and the Principal Stockholders,
     equal to the out of pocket costs and expenses reasonably expected to be
     incurred by the Parent (or the Surviving Corporation, as applicable) in
     connection with the preparation and filing of income Tax Returns of the
     Company and the Subsidiaries which relate to any taxable period ending on
     or before the Closing Date,

to be held in an escrow account (the "Escrow Account") pursuant to the terms of
the Escrow Agreement.

                                      -13-
<PAGE>

          SECTION 2.08. Exchange of Certificates.

          (a) Dissenting Shares. Notwithstanding anything in this Agreement to
the contrary, shares of Common Stock that are issued and outstanding immediately
prior to the Effective Time and that are held by a holder who was entitled to
demand, and has validly demanded, dissenter's rights in accordance with Section
92A of the Nevada Revised Statutes (the "Dissenting Shares") shall not be
converted into the right to receive such holder's portion of the Merger
Consideration unless and until such holder shall have failed to perfect or shall
have effectively withdrawn or lost such holder's dissenter's rights under the
Nevada Revised Statutes, but instead shall be converted into the right to
receive payment from the Surviving Corporation with respect to such Dissenting
Shares in accordance with the Nevada Revised Statutes. If any such holder shall
have failed to perfect or shall have effectively withdrawn or lost such holder's
dissenter's rights, then each of such holder's shares of Common Stock shall be
treated as a share that has been converted as of the Effective Time into the
right to receive such holder's portions of the Closing Merger Consideration and
the Escrow Distribution, if any, in accordance with this Section 2.08.

          (b) Exchange Procedures. At Closing, the Company and the Principal
Stockholders shall deposit the Good Faith Deposit provided by the Parent
pursuant to the Letter of Intent with Parent, for the benefit of the
Stockholders. At the Closing, Parent shall deliver to each Principal Stockholder
his or its portion of the Closing Merger Consideration against delivery by such
Principal Stockholder of a duly executed letter of transmittal, in the form
attached hereto as Exhibit 2.08(b) and certificates representing his, her or its
shares of Common Stock (the "Certificates"). As soon as reasonably practicable
after the Effective Time, Parent shall mail to each other Stockholder entitled
to receive a portion of the Merger Consideration (i) a form of letter of
transmittal, in the form attached hereto as Exhibit 2.08(b) and (ii)
instructions for use in effecting the surrender of such Stockholder's
Certificates, in exchange for such Stockholders' portion of the Merger
Consideration or for submitting an affidavit pursuant to paragraph (g) below.
Each Stockholder shall, upon surrender to Parent of his, her or its Certificate
or Certificates (or affidavit of lost, stolen, mutilated or destroyed
certificates) or upon submission of an affidavit pursuant to paragraph (g)
below, in each case, together with such letter of transmittal, duly executed,
and such other documents as may reasonably be required by Parent, be entitled to
receive in exchange therefor the amount of cash which the number of shares of
Common Stock previously represented by such Certificate or subject to such
affidavit shall have been converted into the right to receive pursuant to
Section 2.06(c), and the Certificates so surrendered shall forthwith be
cancelled. In the event of a transfer of ownership of Common Stock which is not
registered in the transfer records of the Company, payment of any portion of the
Merger Consideration in accordance with this Section 2.08(b) may be made to a
person other than the person in whose name the Certificate so surrendered is
registered if such Certificate shall be properly endorsed or otherwise be in
proper form for transfer and the person requesting such payment shall pay any
transfer or other taxes required by reason of the payment of any applicable
portion of the Merger Consideration to a person other than the registered holder
of such Certificate, or establish to the reasonable satisfaction of Parent that
such taxes have been paid or are not applicable. Until surrendered as
contemplated by this Section 2.08(b), each Certificate shall be deemed at any
time after the Effective Time to represent only the right to receive upon such
surrender the appropriate portions of the Closing Merger Consideration and the
Escrow Distribution, if any, pursuant to the provisions of this Article II. No
interest shall be

                                      -14-

<PAGE>

paid or will accrue on any cash payable to holders of Certificates pursuant to
the provisions of this Article II.

          (c) No Further Ownership Rights in Company Common Stock. All cash paid
upon the surrender of Certificates in accordance with the terms of this Article
II shall be deemed to have been paid in full satisfaction of all rights
pertaining to the shares of Common Stock formerly represented by such
Certificates (other than Dissenting Shares). At the close of business on the day
on which the Effective Time occurs, the share transfer books of the Company
shall be closed, and there shall be no further registration of transfers on the
share transfer books of the Surviving Corporation of the shares of Common Stock
that were outstanding immediately prior to the Effective Time. If, after the
Effective Time, any Certificate is presented to the Surviving Corporation for
transfer, it shall be cancelled against delivery of the appropriate portions of
the Closing Merger Consideration and the Escrow Distribution, if any, to the
holder thereof as provided in this Article II.

          (d) Unpaid Merger Consideration. Any portion of the aggregate amount
of the Merger Consideration which remains undistributed to the holders of the
Certificates after the Effective Time shall remain with Parent and any holders
of the Certificates who have not theretofore complied with this Article II shall
thereafter look only to Parent for, and Parent shall remain liable for, payment
of their claim for such portion of the Merger Consideration.

          (e) No Liability. None of Parent, Merger Sub, the Company, the
Principal Stockholders or the Surviving Corporation shall be liable to any
person in respect of any portion of the Merger Consideration delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law. If any Certificate shall not have been surrendered prior to two
years after the Effective Time (or immediately prior to such earlier date on
which any portion of the Merger Consideration would otherwise escheat to or
become the property of any Governmental Entity (as defined below)), any such
portion of the Merger Consideration shall, to the extent permitted by applicable
law, become the property of Parent, free and clear of all claims or interest of
any person previously entitled thereto.

          (f) Investment of Closing Merger Consideration. Parent may invest any
remaining and unclaimed Closing Merger Consideration as it deems appropriate and
as permitted by law.

          (g) Lost Certificates. If any Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if reasonably
required by Parent, the posting by any person who is not on the Company's list
of Stockholders of record set forth on Exhibit A-2, of a bond in such amount as
Parent may direct as indemnity against any claim that may be made against it
with respect to such Certificate, Parent shall deliver in exchange for such
lost, stolen or destroyed Certificate the applicable portion of the Merger
Consideration in respect thereof pursuant to the provisions of this Article II.

          (h) Withholding Rights. Parent or the Surviving Corporation shall be
entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of Certificates such amounts as Parent
or the Surviving Corporation is required to

                                      -15-

<PAGE>

deduct and withhold with respect to the making of such payment under the Code,
or any provision of state, local or foreign tax law. To the extent that amounts
are so withheld and paid over to the appropriate taxing authority by Parent or
the Surviving Corporation, such withheld amounts shall be treated for all
purposes of this Agreement as having been paid to the holder of the Certificates
in respect of which such deduction and withholding was made by Parent or the
Surviving Corporation.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                    OF THE COMPANY AND PRINCIPAL STOCKHOLDERS

          Except as set forth in the Company's Disclosure Schedule (with
specific reference to the particular Section or subsection of this Agreement to
which the information set forth in such Disclosure Schedule relates) delivered
to the Parent prior to the execution of this Agreement, and as an inducement to
the Parent to enter into this Agreement, the Company and each Principal
Stockholder, jointly and severally hereby represent and warrant to Parent and

and outstanding shares of capital stock, and the current ownership of such
shares.

          (b) Other than the Subsidiaries, there are no other corporations,
partnerships, joint ventures, associations or other entities in which the
Company or any Subsidiary owns, of record or beneficially, any direct or
indirect equity or other interest or any right (contingent or otherwise) to
acquire the same. Other than the Subsidiaries, neither the Company nor any
Subsidiary is a member of (nor is any part of the Business conducted through)
any partnership nor is the Company or any Subsidiary a participant in any joint

existing and in good standing under the laws of its jurisdiction of
incorporation, (ii) has all necessary power and authority to own, operate or
lease the properties and assets owned, operated or leased by such Subsidiary and
to carry on its business as it has been and is currently conducted by such
Subsidiary and (iii) is duly licensed or qualified to do business and is in good
standing in each jurisdiction in which the properties owned or leased by it or
the operation of its business makes such licensing or qualification necessary or
desirable, except to the extent that the failure to be so licensed or qualified

or the Principal Stockholders to carry out their obligations under, and to
consummate the transactions contemplated by, this Agreement, the Printing Supply
Agreement, the Toothpaste Supply Agreement and the Transition Services Agreement
or (y) adversely affect the ability of the Company and the Subsidiaries to
conduct the Business.

          (d) All corporate actions taken by each Subsidiary have been duly
authorized and no Subsidiary has taken any action that in any respect conflicts
with, constitutes a default under or results in a violation of any provision of
its Articles of Incorporation or By-laws (or similar organizational documents).

similar organizational documents), in each case as in effect on the date hereof,
of each Subsidiary have been delivered to Parent.

          SECTION 3.03. Capitalization.

          (a) The authorized capital stock of the Company consists of 3,000
shares of Common Stock. As of the date hereof, 1,304.48 shares of Common Stock
are issued and outstanding, all of which are validly issued, fully paid and
nonassessable. None of the issued and outstanding shares of Common Stock was
issued in violation of any preemptive rights. Except for options that will be
exercised prior to Closing and which are included in the number above, there are
no options, warrants, convertible securities or other rights, agreements,
arrangements or commitments of any character relating to the shares of Common
Stock or obligating either the Principal Stockholders or the Company to issue or
sell any shares of Common Stock, or any other interest in, the Company. The
holder of any agreement, certificate, or other evidence of ownership that,
immediately prior to the Effective Time, represents such options, warrants or
other rights shall cease to have any rights with respect thereto and shall have
no right to receive any portion of the Merger Consideration by reason thereof.
There are no outstanding contractual obligations of the Company to repurchase,
redeem or otherwise acquire any shares of Common Stock or to provide funds to,

          (c) Except as described in this Section 3.20(c) or 3.15(a) of the

          (d) Section 3.19(d) of the Disclosure Schedule sets forth a true and
complete list of all leases and subleases relating to the Real Property and any

addenda and restatements thereto and thereof and all consents, including
consents for alterations, assignments and sublets, documents recording
variations, memoranda of lease, options, rights of expansion, extension, first
refusal and first offer and evidence of commencement dates and expiration
dates). With respect to each of such leases and subleases, neither the Company
nor any Subsidiary has exercised or given any notice of exercise, nor has any
lessor or landlord exercised or received any notice of exercise by a lessor or
landlord of, any option, right of first offer or right of first refusal
contained in any such lease or sublease, including any such option or right
pertaining to purchase, expansion, renewal, extension or relocation

          (e) There are no condemnation proceedings or eminent domain
proceedings of any kind pending or, to the knowledge of the Company and the
Principal Stockholders, threatened against the Real Property.

          (f) All the Real Property is occupied under a valid and current
certificate of occupancy or similar permit, the transactions contemplated by
this Agreement will not require the issuance of any new or amended certificate
of occupancy and, to the knowledge of the

                                      -28-

<PAGE>

Company and the Principal Stockholders, there are no facts that would prevent
the Real Property from being occupied by the Company or any Subsidiary, as the
case may be, after the Closing in the same manner as occupied by the Company or
such Subsidiary immediately prior to the Closing.

          (g) All improvements on the Real Property constructed by or on behalf
of the Company or any Subsidiary or, to the knowledge of the Company and the
Principal Stockholders, constructed by or on behalf of any other Person, were
constructed in material compliance with all applicable Laws (including any
building, planning or zoning Laws) affecting such Real Property.

          (h) No improvements on the Real Property and none of the current uses
and conditions thereof violate any Encumbrance (other than Permitted
Encumbrances), applicable deed restrictions or other applicable covenants,
restrictions, agreements, existing site plan approvals, zoning or subdivision
regulations or urban redevelopment plans as modified by any duly issued
variances, and no permits, licenses or certificates pertaining to the ownership
or operation of all improvements on the Real Property, other than those which
are transferable with the Real Property, are required by any Governmental
Authority having jurisdiction over the Real Property.

          (i) All improvements on any Real Property are wholly within the lot
limits of such Real Property and, except for Permitted Encumbrances, do not
encroach on any adjoining premises or Encumbrance benefiting such Real Property,
and there are no encroachments on any Real Property or any easement or property
right or benefit appurtenant thereto by any improvements located on any
adjoining premises.

          (j) Except as otherwise set forth in Section 3.19(j) of the Disclosure
Schedule, there have been no improvements of a value in excess of $10,000 in the
aggregate made to or constructed on any Real Property within the applicable
period for the filing of mechanics' liens.

          (k) The rental set forth in each lease or sublease of the Leased Real
Property is the actual rental being paid, and there are no separate agreements
or understandings with respect to the same.

          (l) The Company or a Subsidiary, as the case may be, has the full
right to exercise any Options contained in the leases and subleases pertaining
to the Leased Real Property on the terms and conditions contained therein and
upon due exercise would be entitled to enjoy the full benefit of such Options
with respect thereto.

options.

          SECTION 3.21. Assets

          (a) The Company or a Subsidiary, as the case may be, has good and
marketable title to, or, in the case of leased or subleased Assets, valid and
subsisting leasehold interests in, all the Assets (including the Company
Intellectual Property, Inventories, Real Property, Receivables and Tangible
Personal Property), free and clear of all Encumbrances, except Permitted
Encumbrances.

          (b) The Assets (including the Company Intellectual Property,
Inventories, Real Property, Receivables and Tangible Personal Property) together
with the Material Contracts, Licensed Intellectual Property and Company IP
Agreements constitute all the properties, assets and rights forming a part of,
used, held or intended to be used in, and all such properties, assets and rights
as are necessary in the conduct of, the Business as conducted prior to the
consummation of the Pre-Effective Carve-Out Transactions. At all times since the
Reference Statement Date, the Company and the Principal Stockholders have caused
the Assets to be maintained in accordance with good business practice, and all
the Assets are in good operating condition and repair and, to the knowledge of
the Company and the Principal Stockholders, are suitable and usable for the
Company's intended use consistent with the Company's past practice.

          (c) Except with respect to computer software, none of William T.
Evans, J. Robert Lemon, Frank Newton, Rick Land or Robert Christian has any
actual knowledge of any specific fact or circumstance existing on the date
hereof (and not developing over any period of time thereafter) that would
necessarily require as of the date hereof (whether to be made now or in the
future), in accordance with the Company's prior capital expenditure practices, a
material increase in capital expenditures or operating expenditures above
aggregate historical levels, it being understood that capital and operating
expenditures may fluctuate over time without a material increase in overall
capital or operating expenditures.

any Subsidiary has received any written notice that any such customer of the
Business has ceased, or will cease, to use the products, equipment, goods or
services of the Company or any Subsidiary, or has substantially reduced, or will
substantially reduce, the use of such products, equipment, goods or services at
any time.

suppliers of raw materials, supplies, merchandise and other goods for the
Business for the twelve-month period ended December 31, 2005 and the amount for
which each such supplier invoiced the Company and the Subsidiaries during such
period. None of the Principal Stockholders, the Company or any Subsidiary has
received any written notice that any such supplier will not sell raw materials,
supplies, merchandise and other goods to the Company or any Subsidiary at any
time after the Closing on terms and conditions substantially similar to those
used in its current sales to the Business, subject only to general and customary
price increases.

          SECTION 3.24. Employee Benefit Matters.

          (a) Plans and Material Documents. Section 3.24(a) of the Disclosure
Schedule lists (i) all employee benefit plans (as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA")) and all
bonus, stock option, stock purchase, restricted stock, incentive, deferred
compensation, retiree medical or life insurance, supplemental retirement,
severance or other benefit plans, programs or arrangements, and all employment,
termination, severance or other contracts or agreements, whether legally
enforceable or not, to which the Company or any Subsidiary is a party, with
respect to which the Company or any Subsidiary has any obligation or which are
maintained, contributed to or sponsored by the Company or any Subsidiary for the
benefit of any current or former employee, officer or director of the Company or
any Subsidiary, (ii) each employee benefit plan for which the Company or any
Subsidiary could incur liability under Section 4069 of ERISA in the event such
plan has been or were to be terminated, (iii) any plan in respect of which the
Company or any Subsidiary could incur liability under Section 4212(c) of ERISA,
and (iv) any contracts, arrangements or understandings between the Company or
any of its Affiliates and any employee of the Company or of any Subsidiary,
including any contracts, arrangements or understandings relating to the sale of
the Company (collectively, the "Plans"). The Company has furnished to Parent a
complete and accurate copy of each written Plan (along with a written summary of
those Plans not in writing) and a copy of (i) each trust or other funding
arrangement, (ii) the most recent summary plan description and summary of
material modifications for each Plan, if applicable, (iii) the most recently
filed IRS Form 5500, (iv) the most recently received IRS determination letter
for each such Plan, and (v) the most recently prepared actuarial report and
financial statement in connection with each such Plan. There are no other
employee benefit plans, programs, arrangements or agreements, whether formal or
informal, whether in writing or not, to which the Company or any Subsidiary is a
party, with respect to which the Company or any Subsidiary has any obligation or
which are maintained, contributed to or sponsored by the Company or any
Subsidiary for the benefit of any current or former employee, officer or
director of the Company or any Subsidiary. Neither the Company nor any
Subsidiary has any express or implied commitment, whether legally enforceable or
not, (i) to incur liability with respect to or cause to exist any other employee
benefit plan, program or arrangement, (ii) to enter into any contract or
agreement to provide compensation or benefits to any individual, or (iii) to
modify, change or terminate any Plan, other than with respect to a modification,
change or termination required by ERISA, the Code or other applicable Law.

          (b) Absence of Certain Types of Plans. None of the Plans is a
multiemployer plan (within the meaning of Section 3(37) or 4001(a)(3) of ERISA)
(a "Multiemployer Plan") or

                                      -31-

<PAGE>

a single employer pension plan (within the meaning of Section 4001(a)(15) of
ERISA) for which the Company or any Subsidiary could incur liability under
Section 4063 or 4064 of ERISA (a "Multiple Employer Plan"). None of the Plans
provides for the payment of separation, severance, termination or similar-type
benefits to any Person or obligates the Company or any Subsidiary to pay
separation, severance, termination or similar-type benefits solely as a result
of any transaction contemplated by this Agreement or as a result of a "change in
control", within the meaning of such term under Section 280G of the Code. Except
as required by Law, none of the Plans provides for or promises retiree medical,
disability or life insurance benefits to any current or former employee, officer
or director of the Company or any Subsidiary. Each of the Plans is subject only
to the Laws of Canada, the United States or a political subdivision thereof.

          (c) Compliance with Applicable Law. Each Plan has been operated in
material compliance with the terms of such Plan and the requirements of all
applicable Law, including ERISA and the Code, and all Persons who participate in
the operation of such Plans and all Plan "fiduciaries" (within the meaning of
Section 3(21) of ERISA) have acted in all material respects in accordance with
the provisions of all applicable Law, including ERISA and the Code. No Action is
pending or, to the knowledge of the Company and the Principal Stockholders,
threatened with respect to any Plan (other than claims for benefits in the
ordinary course).

          (d) Qualification of Certain Plans. Each Plan that is intended to be
qualified under Section 401(a) of the Code or Section 401(k) of the Code has
received a favorable determination letter from the IRS that it is so qualified,
and each trust established in connection with any Plan that is intended to be
exempt from federal income taxation under Section 501(a) of the Code has
received a determination letter from the IRS that it is so exempt, and no fact
or event has occurred since the date of such determination letter from the IRS
that could reasonably be expected to adversely affect the qualified status of
any such Plan or the exempt status of any such trust. Each trust maintained or
contributed to by the Company or any Subsidiary that is intended to be qualified
as a voluntary employees' beneficiary association and that is intended to be
exempt from federal income taxation under Section 501(c)(9) of the Code has
received a favorable determination letter from the IRS that it is so qualified
and so exempt, and no fact or event has occurred since the date of such
determination by the IRS that could reasonably be expected to adversely affect
such qualified or exempt status.

          (e) Absence of Certain Liabilities and Events. There has been no
prohibited transaction (within the meaning of Section 406 of ERISA or Section
4975 of the Code) with respect to any Plan that has not been properly corrected.
Neither the Company nor any Subsidiary has incurred any liability for any
penalty or tax arising under Section 4971, 4972, 4980, 4980B, 4980D or 6652 of
the Code or any liability under Section 502 of ERISA, and, to the knowledge of
the Company and the Principal Stockholders, no fact or event exists that could
give rise to any such liability. Neither the Company nor any Subsidiary has
incurred any liability under, arising out of or by operation of Title IV of
ERISA (other than liability for premiums to the Pension Benefit Guaranty
Corporation arising in the ordinary course), including any liability in
connection with (i) the termination or reorganization of any employee benefit
plan subject to Title IV of ERISA or (ii) the withdrawal from any Multiemployer
Plan or Multiple Employer Plan, and, to the knowledge of the Company and the
Principal Stockholders, no fact or event exists that could give rise to any such
liability. No complete or partial termination has occurred

                                      -32-

<PAGE>

within the five years preceding the date hereof with respect to any Plan that is
subject to Title IV of ERISA. No reportable event (within the meaning of Section
4043 of ERISA) has occurred or is expected to occur with respect to any Plan
subject to Title IV of ERISA. No Plan had an accumulated funding deficiency
(within the meaning of Section 302 of ERISA or Section 412 of the Code), whether
or not waived, as of the most recently ended plan year of such Plan. None of the
assets of the Company or any Subsidiary is the subject of any lien arising under
Section 302(f) of ERISA or Section 412(n) of the Code; neither the Company nor
any Subsidiary has been required to post any security under Section 307 of ERISA
or Section 401(a)(29) of the Code; and no fact or event exists which could
reasonably be expected to give rise to any such lien or requirement to post any
such security.

          (f) Plan Contributions and Funding. All contributions, premiums or
payments required to be made with respect to any Plan have been made. All such
contributions have been fully deducted for income tax purposes and no such
deduction has been challenged or disallowed by any Governmental Authority, and
no fact or event exists that could reasonably be expected to give rise to any
such challenge or disallowance. As of the Closing, no Plan that is subject to
Title IV of ERISA will have an "unfunded benefit liability" (within the meaning
of Section 4001(a)(18) of ERISA).

          SECTION 3.25. Labor Matters. (a) Neither the Company nor any
Subsidiary is a party to any collective bargaining agreement or other labor
union contract applicable to persons employed by the Company or any Subsidiary,
and to the knowledge of the Company and the Principal Stockholders, there are
currently no organizational campaigns, petitions or other unionization
activities seeking recognition of a collective bargaining unit which could
affect the Company or any Subsidiary; (b) there are no controversies, strikes,
slowdowns or work stoppages pending or, to the knowledge of the Company and the
Principal Stockholders, threatened between the Company or any Subsidiary and any
of their respective employees, and neither the Company nor any Subsidiary has
experienced any such controversy, strike, slowdown or work stoppage within the
past three years; (c) neither the Company nor any Subsidiary has breached or
otherwise failed to comply with the provisions of any collective bargaining or
union contract, and there are no grievances outstanding against the Company or
any Subsidiary under any such agreement or contract which could have a Material
Adverse Effect; (d) there are no unfair labor practice complaints pending
against the Company or any Subsidiary before the National Labor Relations Board
or any other Governmental Authority or any current union representation
questions involving employees of the Company or any Subsidiary which could have
a Material Adverse Effect; (e) the Company and each Subsidiary has withheld and
paid to the appropriate Governmental Authority or is holding for payment not yet
due to such Governmental Authority all amounts required to be withheld from
employees of the Company or any Subsidiary and is not liable for any arrears of
wages, Taxes, penalties or other sums for failure to comply with any of the
foregoing; (f) the Company and each Subsidiary has paid in full to all their
respective employees or adequately accrued for in accordance with GAAP all
wages, salaries, commissions, bonuses, benefits and other compensation due to or
on behalf of such employees; (g) there is no claim with respect to payment of
wages, salary or overtime pay that has been asserted or is now pending or
threatened before any Governmental Authority with respect to any Persons
currently or formerly employed by the Company or any Subsidiary; (h) neither the
Company nor any Subsidiary is a party to, or otherwise bound by, any consent
decree with, or citation by, any Governmental Authority relating to employees or
employment

                                      -33-

<PAGE>

practices; (i) there is no charge or proceeding before any Governmental
Authority with respect to a violation of any occupational safety or health
standard that has been asserted or is now pending or threatened with respect to
the Company or any Subsidiary; and (j) there is no charge of discrimination in
employment or employment practices, for any reason, including age, gender, race,
religion or other legally protected category, which has been asserted or is now
pending or threatened before the United States Equal Employment Opportunity
Commission, or any other Governmental Authority in any jurisdiction in which the
Company or any Subsidiary has employed or currently employs any Person.

          SECTION 3.26. Key Employees.

          (a) Section 3.26 of the Disclosure Schedule lists the name, place of
employment, the current annual salary rates, bonuses, deferred or contingent

Subsidiary all inventions made by them within the scope of their employment
during such employment and for a reasonable period thereafter.

          SECTION 3.27. Certain Interests.

          (a) To the knowledge of the Company and the Principal Stockholders, no
Principal Stockholder, officer or director of the Company or any Subsidiary and
no relative or spouse (or relative of such spouse) who resides with, or is a
dependent of, any such Principal Stockholder, officer or director:

          (i) has any direct or indirect financial interest in any competitor,
     supplier or customer of the Company or any Subsidiary or the Business;
     provided, however, that the ownership of securities representing no more
     than two percent of the outstanding voting power of any competitor,
     supplier or customer whose equity securities are publicly traded shall not
     be deemed to be a "financial interest" as long as the Person owning such
     securities has no other material connection or relationship with such
     competitor, supplier or customer;

          (ii) owns, directly or indirectly, in whole or in part, or has any
     other interest in any tangible or intangible property that the Company or

          (b) None of the Company or any Subsidiary has any Liability or any

and the Principal

                                      -34-

<PAGE>

Stockholders, to any relative or spouse (or relative of such spouse) who resides
with, or is a dependent of, any such officer, director or Principal Stockholder.

          (ii) All Taxes required to be shown on such Tax Returns the due date

the knowledge of the Company and the Principal Stockholders, no basis exists for

(iii) in the event that such protective order or other remedy is not obtained,
or the Company waives compliance with this Section 5.03, furnish only that
portion of such confidential information which is legally required to be
provided and exercise its commercially reasonable efforts to obtain assurances
that confidential treatment will be accorded such information, and (iv) in the
event that this Agreement terminates prior to the consummation of the Merger,
promptly furnish (as soon as practicable following such termination) to the
Company any and all copies (in whatever form or medium) of all such confidential
information then in the possession of Parent or Merger Sub or any agent,
representative, Affiliate, employee, officer or director of the foregoing and
destroy any and all additional copies then in the possession of the Parent or
Merger Sub or any of their respective agents, representatives, Affiliates,
employees, officers and directors of such information and of any analyses,
compilations, studies or other documents prepared, in whole or in part, on the
basis thereof; provided, however, that this sentence shall not apply to any
information that, at the time of disclosure, is available publicly and was not
disclosed in breach of this Agreement by Parent, Merger Sub, or their respective
agents, representatives, Affiliates, employees, officers or directors; and
provided further that, with respect to Company Intellectual Property, specific
information shall not be deemed to be within the foregoing exception merely
because it is embraced in general disclosures in the public domain. In addition,
with respect to Company Intellectual Property, any combination of features shall
not be deemed to be within the foregoing exception merely because the individual
features are in the public domain unless the combination itself and its
principle of operation are in the public domain.

          (c) Notwithstanding anything herein to the contrary, each party hereto
(and its representatives, agents and employees) may consult any tax advisor
regarding the tax treatment and tax structure of the transactions contemplated
hereby and may disclose to any person, without limitation of any kind, the tax
treatment and tax structure of such transactions and all materials (including
opinions and other tax analyses) that are provided relating to such treatment or
structure.

reasonable efforts to obtain those authorizations, consents, orders and

all such Required Governmental Consents.

                                      -45-

<PAGE>

          (b) The Company and the Subsidiaries shall give promptly such notices
to third parties and use its or their commercially reasonable efforts to obtain
those third party consents and estoppel certificates that are set forth on
Section 5.04(b) of the Disclosure Schedule (the "Required Third-Party
Consents").

          (c) Parent shall cooperate and use all reasonable efforts to assist
the Company in giving such notices and obtaining the Required Third-Party
Consents; provided, however, that Parent shall have no obligation to give any
guarantee or other consideration of any nature in connection with any such
notice, consent or estoppel certificate or to consent to any change in the terms
of any agreement or arrangement which Parent in its sole discretion may deem
adverse to the interests of Parent, the Company or any Subsidiary.

          (d) Upon the terms and subject to the conditions of this Agreement,
each of the parties hereto shall use commercially reasonable efforts to take, or
cause to be taken, all action, to do, or cause to be done, all other things
necessary, proper or advisable to consummate and make effective as promptly as
practical following the Effective Time the transactions contemplated by this
Agreement, to obtain in a timely manner all waivers, consents and approvals
required by this Agreement and to effect all necessary registrations and filings
and otherwise to satisfy or cause to be satisfied all conditions to its
obligations under this Agreement. All parties agree that the obligations under
this Agreement and pursuant to this Section 5.04(d) may require commercially
reasonable efforts to cooperate after the Effective Time in order to preserve
the rights and benefits of the Surviving Corporation.

          SECTION 5.05. Use of Intellectual Property.

          (a) The Principal Stockholders and the Company acknowledge that from
and after the Effective Time, the name "Pro-Dentec" and all similar or related
names, marks and logos (all of such names, marks and logos being the "Company
Marks") shall be owned by Parent and the Surviving Corporation and neither
Principal Stockholders nor any of its Affiliates shall have any rights in the
Company Marks and that the Principal Stockholders nor any of its Affiliates will
contest the ownership or validity of any rights of Parent or the Surviving
Corporation in or to the Company Marks.

          (b) From and after the Effective Time, neither the Principal
Stockholders nor any of their Affiliates shall use any of the Company
Intellectual Property or any of the Licensed Intellectual Property.

          SECTION 5.06. Non-Competition.

          (a) For a period of two years after the Effective Time (the
"Restricted Period"), the Principal Stockholders shall not engage, directly or
indirectly, in any business anywhere that manufactures, produces or supplies
products or services of the kind manufactured, produced or supplied by the
Business as of the Closing Date or, without the prior written consent of Parent,
directly or indirectly, own an interest in, manage, operate, join, control, lend
money or render financial or other assistance to or participate in or be
connected with, as an officer, employee, partner, stockholder, consultant or
otherwise, any Person that competes with Parent, the Business, the Company or
any Subsidiary in manufacturing, producing or supplying products

                                      -46-

<PAGE>

or services of the kind manufactured, produced or supplied by the Company or any
Subsidiary as of the Closing Date; provided, however, that, for the purposes of
this Section 5.06, ownership of securities having no more than two percent of
the outstanding voting power of any competitor whose equity securities are
publicly traded, without more, shall not be deemed to be in violation of this
Section 5.06 as long as the Person owning such securities has no other material
connection or relationship with such competitor; and provided, further, that the
Principal Stockholders may engage in the business set forth in Section 5.06(a)
of the Disclosure Schedule.

          (b) As a separate and independent covenant, each Principal Stockholder
agrees with Parent that, for a period of six months following the Effective Time
(and for a period of 24 months with respect to Scott Bradshaw, Marvin Terrell
and Bill Sale), each Principal Stockholder and each Person Controlled by any of
them (individually or collectively, directly or indirectly) will not in any way,
directly or indirectly, interfere with or attempt to interfere with (including,
but not limited to, hire or otherwise employ) any officers, employees,
representatives or agents of the Company or any Subsidiary as of the date
hereof, or induce or attempt to induce any of them to leave the employ of the
Company or any Subsidiary or violate the terms of their contracts, or any
employment arrangements, with the Company or any Subsidiary; provided, however,
that nothing in this paragraph shall be deemed to restrict the Principal
Stockholders or Person Controlled by any of them (individually or collectively,
directly or indirectly) from (i) soliciting or hiring officers, employees,
representatives or agents of the Company or any Subsidiary whose association
with the Company or the applicable Subsidiary has been terminated by the Company
without cause and through no violation of this paragraph by the Principal
Stockholders and no violation of the Side Agreements by the Side Agreement
Parties, or (ii) initiating and conducting a general solicitation for employees
(for example, newspaper or internet advertisement) so long as each Principal
Stockholder and each Person Controlled by any of them (individually or
collectively, directly or indirectly) does not (x) directly or specifically
solicit any officers, employees, representatives or agents of the Company or any
Subsidiary as of the date hereof or (y) hire any such persons.

          (c) The Restricted Period shall be extended by the length of any
period during which any Principal Stockholder is in breach of the terms of this
Section 5.06.

          (d) The Principal Stockholders acknowledge that the covenants of the
Principal Stockholders set forth in this Section 5.06 are an essential element
of this Agreement and that, but for the agreement of the Principal Stockholders
to comply with these covenants, Parent would not have entered into this
Agreement. The Principal Stockholders acknowledge that this Section 5.06
constitutes an independent covenant that shall not be affected by performance or
nonperformance of any other provision of this Agreement by Parent. Each
Principal Stockholder is hereby advised to independently consult with its own
counsel and agrees that the covenants set forth in this Section 5.06 are
reasonable and proper.

          SECTION 5.07. Release. The Principal Stockholders covenant and agree,
on or prior to the Closing Date, to execute and deliver to the Company, for the
benefit of the Company, each Subsidiary and the Surviving Corporation, a general
release and discharge, in the form attached hereto as Exhibit 5.07 (each, a
"General Release").

                                      -47-
<PAGE>

          SECTION 5.08. Intercompany Arrangements.

          (a) Prior to the Closing Date, the Company and the Principal
Stockholders shall cause any contract or arrangement that is disclosed (or
should have been disclosed) in Section 3.17(a)(viii) of the Disclosure Schedule,
other than those contracts or arrangements set forth in Section 5.08 of the
Disclosure Schedule, to be terminated or otherwise amended to exclude the
Company and any Subsidiaries as a party thereto.

          (b) Immediately prior to the consummation of the Closing Date, the
Principal Stockholders shall contribute, or cause to be contributed, to the
capital of the Company, the difference between (i) the intercompany Indebtedness
owed by the Company and any Subsidiary to the Principal Stockholders and its
Affiliates (other than the Company and the Subsidiaries) as of the Closing Date
and (ii) the intercompany Indebtedness owed by the Principal Stockholders and
its Affiliates (other than the Company and the Subsidiaries) to the Company as
of the Closing Date and all such intercompany Indebtedness shall cease to exist
and be of no further force or effect.

          SECTION 5.09. Further Action. Each of the parties hereto shall use all
reasonable efforts to take, or cause to be taken, all appropriate action, do or
cause to be done all things necessary, proper or advisable under applicable Law,
and to execute and deliver such documents and other papers, as may be required
to carry out the provisions of this Agreement, the Printing Supply Agreement,
the Side Agreements, the Toothpaste Supply Agreement, the Transition Services
Agreement, the Escrow Agreement, the General Releases, the White Drive Lease and
the Wal-Mart Sublease to which it is a party and consummate and make effective
the transactions contemplated hereby and thereby.

          SECTION 5.10. Stockholder Approval. At any meeting of the
Stockholders, and at any adjournment thereof, and upon each request to execute a
written consent in lieu of a meeting of the Stockholders, each Principal
Stockholder agrees that he, she or it shall vote his, her or its shares of
Common Stock in a manner that is consistent with the requirements of this
Agreement, and in favor of (i) the Merger, (ii) the approval of this Agreement
and (iii) the transactions contemplated hereby. The Company or the Principal
Stockholders will call a special meeting of the stockholders of the Company in
accordance with the Company's bylaws to be held on or prior to November 28,
2006.

          SECTION 5.11. No Solicitation or Negotiation. The Principal
Stockholders and the Company agree that between the date of this Agreement and
the earlier of (a) the Closing and (b) the termination of this Agreement, none
of the Principal Stockholders, the Company or the Subsidiaries or any of their
respective Affiliates, officers, directors, representatives or agents will (i)
solicit, initiate, consider, encourage or accept any other proposals or offers
from any Person (A) relating to any acquisition or purchase of all or any
portion of the capital stock of the Company or any Subsidiary or the Assets
(other than in the ordinary course of business consistent with past practice) or
(B) to enter into any merger, consolidation, business combination,
recapitalization, reorganization or other extraordinary business transaction
involving or otherwise relating to the Company or any Subsidiary or (ii)
participate in any discussions, conversations, negotiations and other
communications regarding, or furnish to any other Person any information with
respect to, or otherwise cooperate in any way, assist or

                                      -48-

<PAGE>

participate in, facilitate or encourage any effort or attempt by any other
Person to seek to do any of the foregoing.

          SECTION 5.12. Chlorhexidine.

          (a) The Principal Stockholders agree that in the event that:

               (i) revenue resulting from sales of the Company's chlorhexidine
          product ("CHX") in the state of Florida during the three month period
          beginning on October 1, 2006 and ending on December 31, 2006 (the
          "2006 CHX Period") is equal to or less than $32,101; and

               (ii) revenue resulting from the sales of CHX by the Company in
          the entire United States during the 2006 CHX Period is equal to or
          less than $341,705,

then the amount that is equal to the percentage decrease from $32,101 to the
revenue resulting from the sales of CHX by the Company in the state of Florida
during the 2006 CHX Period, multiplied by $167,467, shall be a "Loss" as defined
in Section 9.02 hereof and the Principal Stockholders shall (after the
resolution of any objection submitted during the Objection Period pursuant to
Section 5.12(c) below) indemnify and hold the Parent harmless from such Loss in
accordance with the provisions of Article IX, and subject to the limitations set
forth in 9.04, and conditioned in any event on compliance by Parent and the
Surviving Corporation of its covenants set forth in Section 5.12(b). For
purposes of this Section 5.12 "revenue resulting from the sales of CHX" shall
mean the total dollar amount that the Company recognized in its profit and loss
account from the sale of CHX during the applicable period, calculated in
accordance with the Company's past practice.

          (b) From and after the Closing until the expiration of the 2006 CHX
Period, Parent and the Surviving Corporation will use their commercially
reasonable efforts to promote the sale of CHX in Florida and to bring the sales
levels of CHX in Florida to 2005 levels prior to the commencement of the 2006
CHX Period, in each case implementing methods and efforts not inferior to those
implemented by the Company prior to the Closing. With respect to sales of CHX in
the entire United States, Parent and the Surviving Corporation will promote
sales of CHX consistent with the past practice of the Company prior to the
Closing. Without limiting the generality of the foregoing, without the consent
of the Principal Stockholders, Parent and the Surviving Corporation will not
alter the selling price of CHX, make significant changes to the sales force
responsible for selling CHX, or take any action that is reasonably likely to be
detrimental to sales of CHX.

          (c) Within 30 days after the expiration of the 2006 CHX Period, Parent
will provide the Principal Stockholders with notice of the amount, if any,
determined by Parent to constitute a Loss pursuant to Section 5.12(a) above. If,
within 15 business days after receiving such notice (the "Objection Period"),
the Principal Stockholders have not provided notice to Parent of their objection
or intention to review Parent's determination pursuant to Section 5.12(d) below,
Parent's determination of the Loss will be final and binding on the parties
hereto. In the event that the Principal Stockholders provide notice of their
objection or intention to

                                      -49-

<PAGE>

review Parent's determination within the Objection Period, the Principal
Stockholders will have no obligation to indemnify the Parent or the Surviving
Corporation for Losses pursuant to Section 5.12(a) until the amount of such Loss
is determined by Parent and the Principal Stockholders mutually, or absent such
mutual determination, by an accounting firm of national reputation selected in
good faith by the parties hereto.

          (d) Parent and the Surviving Corporation will keep complete and
accurate records of its sales of CHX in Florida and in the entire United States
prior to and during the 2006 CHX Period and will document its efforts to promote
sales of CHX in Florida and in the entire United States prior to and during the
2006 CHX Period. Upon the Principal Stockholder's reasonable request, Parent and
the Surviving Corporation will promptly provide copies of such records and
documentation to the Principal Stockholders (or their representatives) for the
purpose of verifying the Parent's determination of the amount, if any,
determined by Parent to constitute a Loss pursuant to Section 5.12(a).

                                   ARTICLE VI

                                EMPLOYEE MATTERS

          SECTION 6.01. Retained Employees. As of the Closing Date, Parent will
enter into a mutually acceptable employment agreement with certain key
employees, as set forth in Exhibit 6.01 hereto, of the Company and the
Subsidiaries (a "Retained Employee"). Each Retained Employee, and any other
employees employed by the Business after the Effective Time, shall continue to
participate in the employee benefit plans sponsored by the Company and shall not
be eligible to participate in the employee benefit plans of Parent after the
Effective Time, except as otherwise provided in such plans, as amended from time
to time.

                                   ARTICLE VII

                                   TAX MATTERS

          SECTION 7.01. Indemnity.

          (a) Pursuant and subject to the provisions of Article IX (except as
expressly and specifically set forth in this Article VII), the Parent
Indemnified Parties shall be indemnified and held harmless from and against the
amount of any Loss suffered by any one or more of them resulting from or arising
out of, without duplication to the extent of any amounts set aside for such
Taxes in the Escrow Account, (i) all (A) income Taxes (or the non-payment
thereof) of the Company and the Subsidiaries, whether or not such income Taxes
have been reserved for on the Reference Statement of Net Assets, for all taxable
periods ending on or before the Closing Date and, to the extent applicable, the
portion through the end of the Closing Date for any taxable period that includes
(but does not end on) the Closing Date (the "Pre-Closing Tax Period"), (B) other
Taxes (or the non-payment thereof) of the Company and the Subsidiaries to the
extent such other Taxes have not properly been reserved for on the Reference
Statement of Net Assets (but subject to clause (C) of this Section 7.01(a)(i)),
for all taxable periods ending on or before the Closing Date and, to the extent
applicable, the Pre-Closing Tax Period, and (D) all Taxes

                                      -50-

<PAGE>

resulting from the Pre-Effective Carve-out Transactions, whether or not such
income Taxes have been reserved for on the Reference Statement of Net Assets;
(ii) all Taxes (or the non-payment thereof) of any member of an affiliated,
consolidated, combined or unitary group of which the Company or any of the
Subsidiaries (or any predecessor of any of the foregoing) is or was a member on
or before the Closing Date, including pursuant to U.S. Treasury Regulation
Section 1.502-6 or any analogous or similar state, local, or foreign law or
regulation, and (iii) any and all Taxes (or the nonpayment thereof) of any
Person (other than the Company and Subsidiaries) imposed on the Company and the
Subsidiaries as a transferee or successor by contract or pursuant to any law,
rule, or regulation, which Taxes relate to an event or transaction occurring on
or before the Closing Date.

          (b) For purposes of this Section 7.01, whenever it is necessary to
determine the amount of Loss in respect of Taxes (or the non-payment thereof) of
the Company or any Subsidiary for a taxable period that includes but does not
end on the Closing Date (a "Straddle Period"), the determination of the Taxes
for the Pre-Closing Tax Period, and the portion of the taxable year or period
beginning after, the Closing Date shall be determined: (i) in the case of Taxes
that are either (x) based upon or related to income or receipts, or (y) imposed
in connection with any distribution, sale or other transfer or assignment of
property (and expressly including within this clause (i) the final federal
income Tax Return of the consolidated group encompassing the Company and the
Subsidiaries) by assuming that the Company or the Subsidiary had a taxable year
or period which ended at the close of the Closing Date and closing the books of
the Company or Subsidiary as of such date (and for such purpose the taxable
period of any partnership, joint venture or other pass-through entity in which
the Company or any Subsidiary holds a beneficial interest shall be deemed to
terminate at such time), except that exemptions, allowances or deductions that
are calculated on an annual basis, such as the deduction for depreciation, shall
be apportioned on a time basis; and, (ii) in the case of Taxes not described in
clause (i) that are imposed on a periodic basis and measured by the level of any
item, shall be deemed to be the amount of such Taxes (including any minimum) for
the entire period (or, in the case of such Taxes determined on an arrears basis,
the amount of such Taxes for the immediately preceding period) multiplied by a
fraction the numerator of which is the number of calendar days in the
Pre-Closing Tax Period and the denominator of which is the number of calendar
days in the entire period. Any credit or refund resulting from an overpayment of
Taxes for a Straddle Period shall be prorated based upon the method employed in
this paragraph (b) taking into account type of the Tax to which the refund
relates. In the case of any Tax based upon or measured by capital (including net
worth or long-term debt) or intangibles, any amount thereof required to be
allocated under this Section 7.01(b) shall be computed by reference to the level
of such items on the date of the Closing. All determinations necessary to effect
the foregoing allocations shall be made in a manner consistent with prior
practice of the Company and the Subsidiaries.

          (c) It is expressly provided that for purposes of this Section 7.01,
the Taxes associated with the Pre-Closing Tax Period shall include any and all
Taxes of the Company and the Subsidiaries that are attributable to the
Pre-Effective Carve-Out Transactions. For this purpose, if the Pre-Effective
Carve-Out Transactions are deemed to have been consummated on the Closing Date,
it is further expressly provided that in determining the Taxes for any
applicable Straddle Period, the Pre-Effective Carve-Out Transactions shall be
deemed to have occurred on the Closing Date but prior to the Closing and,
accordingly, it is hereby acknowledged and agreed

                                      -51-

<PAGE>

that the so-called "next-day" rule of U.S. Treasury Regulations Section
1.1502-76(b)(2)(ii)(B) (or any other potentially applicable law or regulation
that might otherwise treat the Pre-Effective Carve-Out Transactions as occurring
after the Closing Date) shall not apply in any case.

          SECTION 7.02. Returns and Payments

          (a) From the date of this Agreement through the Closing, the Company
and the Principal Stockholders shall prepare and file or otherwise furnish in
proper form to the appropriate Taxing Authority (or cause to be prepared and
filed or so furnished) in a timely manner all Tax Returns relating to the
Company and the Subsidiaries that are due on or before the Closing Date;
provided, however, that Parent and/or the Surviving Corporation will bear all
costs and expenses associated with the preparation and filing of any Tax Return
required to be prepared with respect to the period beginning on November 1,
2006, and ending on the Closing Date, including all accountants' and auditors'
fees. The Company shall cause such Tax Returns to be prepared and filed, in a
manner consistent with past practice of the Company (subject to any departure
required to comply with any Applicable Law). The Parent shall cause to be
prepared and filed all Tax Returns relating to the Company and the Subsidiaries
that are due after the date of the Closing; provided, however, that the Parent
(or the Surviving Corporation, as applicable) shall be entitled to reimbursement
from the amounts set aside therefor in the Escrow Account for its out of pocket
costs and expenses associated with the preparation and filing of income Tax
Returns of the Company and the Subsidiaries which relate to any taxable period
ending on or before October 31, 2006. With respect to any such Tax Return
relating to the Company and the Subsidiaries that include any period ending on
or before the Closing Date, the filing party shall provide the other party and
its authorized representatives with a copy of such completed Tax Return,
together with appropriate supporting information and schedules, as soon as
reasonably practicable prior to the due date (including any extension hereof)
for the filing of such Tax Return, and such other party and its authorized
representatives shall have the right to review and comment on such Tax Return
and statement prior to the filing of such Tax Return.

          (b) The Principal Stockholders shall pay or cause the Company to pay
all Taxes with respect to the Company and the Subsidiaries due and payable on or
before the Closing Date, and Parent shall pay or cause to be paid all Taxes due
and payable after the Closing Date. The Principal Stockholders will promptly
reimburse Parent for any income Taxes paid by Parent after the Closing Date but
which relate to periods ending on or prior to the Closing Date.

          SECTION 7.03. Refunds. Any Tax refund (including any interest with
respect thereto or any credit against future tax liability) relating to the
Company or any Subsidiary for any taxable period ending on or prior to the date
of the Closing (except for any refund included on the Reference Statement of Net
Assets and any refund arising in respect of Taxes for which the Principal
Stockholders are not liable under Section 7.01, which shall be the property of
Parent, and if paid to the Company or the Principal Stockholders, shall be paid
over promptly to Parent) shall be the property of the Stockholders, and if
received by Parent, the Company or any Subsidiary shall be paid over promptly
into the Expense Fund under the Escrow Agreement (or, if such fund is then
non-existent, to the Stockholders). Notwithstanding the foregoing, (a) any Tax
refund (or equivalent benefit to the Stockholders through a reduction in Tax
liability) for a taxable period ending on or before the date of the Closing
arising out of the carryback of a loss

                                      -52-

<PAGE>

of credit incurred by the Company or any Subsidiary in a taxable period ending
after the Closing shall be the property of Parent and, if received by the
Company or the Principal Stockholders, shall be paid over promptly to Parent;
and (b) if, and to the extent that, as of such time, if any, as Parent shall
receive a refund that would be the property of the Stockholders and payable to
the Expense Fund under the Escrow Agreement or to the Stockholders under this
Section 7.03, Taxes have been asserted in writing that would be required to be
indemnified by the Principal Stockholders hereunder, all or part of such refund
up to an amount equal to 120% of such asserted Taxes shall, at the option of
Parent, be deposited by the Parent into an indemnity escrow fund for
satisfaction of any amounts indemnifiable under this Article VII which have been
asserted or subsequently are asserted, until the time set forth in clause (ii)
of Section 7.05 of this Agreement with respect to any asserted amounts (or, if
earlier, expiration of the applicable statute of limitations), at which time any
balance remaining in the such indemnity escrow fund from such deposited amount
after payment of any claims shall be paid into the Expense Fund under the Escrow
Agreement (or, if such fund is then non-existent, to the Stockholders).

          SECTION 7.04. Contests.

          (a) After the Closing, Parent shall promptly notify the Principal
Stockholders in writing of any written notice of a proposed assessment or claim
in an audit or administrative or judicial proceeding of Parent or any of the
Company and the Subsidiaries which, if determined adversely to the taxpayer,
would be grounds for indemnification under this Article VII; provided, however,
that the failure to give such notice will not affect Parent's right to
indemnification under this Article VII except to the extent, if any, that, but
for such failure, the Principal Stockholders could have avoided all or a portion
of the Tax liability in question.

          (b) In the case of an audit or administrative or judicial proceeding
that relates to taxable periods ending on or before the date of the Closing, the
Principal Stockholders shall have the right at their expense to participate in
such audit or proceeding, and such audit or proceeding shall be deemed to be a
Third Party Claim pursuant to Section 9.05(b), except to the extent that the
provisions thereof are inconsistent with the other provisions of this Section
7.04.

          (c) With respect to any Tax audit or proceeding for a taxable period
that begins before the date of the Closing, neither Parent nor the Principal
Stockholders shall enter into any compromise or agree to settle any claim
pursuant to such audit or proceeding which would adversely affect the other
party for such taxable period or a subsequent taxable period without the written
consent of the other party, which consent may not be unreasonably withheld.
Parent and the Principal Stockholders agree to cooperate, and Parent agrees to
cause the Company and the Subsidiaries to cooperate, in the defense against or
compromise of any claim in any such audit or proceeding.

          SECTION 7.05. Time of Payment. Payment by the Principal Stockholders
of any amounts due under this Article VII in respect of Taxes not funded from
the Escrow Account shall be made (a) at least three Business Days before the due
date of the applicable estimated or final Tax Return required to be filed by

payable, an assessment of a Tax by a taxing authority, or a "determination" as
defined in Section 1313(a) of the Code. If liability under this Article VII is
in respect of costs or expenses other than Taxes, payment by Parent of any
amounts due under this Article VII shall be made within five Business Days after
the date when the Principal Stockholders have been notified by Parent that the
Principal Stockholders have a liability for a determinable amount under this
Article VII and is provided with calculations or other materials supporting such
liability.

          SECTION 7.06. Tax Cooperation and Exchange of Information. Each of the
Principal Stockholders and Parent shall provide each other with such cooperation
and information as either of them reasonably may request of the other (and
Parent shall cause the Company and the Subsidiaries to provide such cooperation
and information) in filing any Tax Return, amended Tax Return or claim for
refund, determining a liability for Taxes or a right to a refund of Taxes or
participating in or conducting any audit or other proceeding in respect of Taxes
or making representations to or furnishing information to parties subsequently
desiring to purchase any part of the Purchased Assets, the Business, the Company
or the Subsidiaries from Parent. Such cooperation and information shall include
providing copies of relevant Tax Returns or portions thereof, together with
related work papers and documents relating to rulings or other determinations by
taxing authorities. Each Principal Stockholders and Parent shall make themselves
(and their respective employees) reasonably available on a mutually convenient
basis to provide explanations of any documents or information provided under
this Section 7.06. Notwithstanding anything to the contrary in Section 5.02
hereto, each of the Principal Stockholders and the Parent shall retain all Tax
Returns, work papers and all material records or other documents in its
possession (or in the possession of its Affiliates) relating to Tax matters of
the Company or any Subsidiary for any taxable period that includes the date of
the Closing and for all prior taxable periods until the later of (i) the
expiration of the statute of limitations of the taxable periods to which such
Tax Returns and other documents relate, without regard to extensions or (ii) six
years following the due date (without extension) for such Tax Returns. After
such time, before the Principal Stockholders or Parent shall dispose of any such
documents in its possession (or in the possession of its Affiliates), the other
party shall be given an opportunity, after 90 days prior written notice, to
remove and retain all or any part of such documents as such other party may
select (at such other party's expense). Any information obtained under this
Section 7.06 shall be kept confidential, except as may be otherwise necessary in
connection with the filing of Tax Returns or claims for refund or in conducting
an audit or other proceeding.

is placed under applicable Law for Conveyance Taxes which become payable in
connection with the transactions contemplated by this Agreement shall be
responsible for the payment of such Conveyance Taxes. Each of the Principal
Stockholders, after the review and consent by Parent, shall file such
applications and documents as shall permit any such Conveyance Taxes to be
assessed and paid on or prior to the Closing in accordance with any available
pre-sale filing procedure. Parent shall execute and deliver all instruments and
certificates necessary to enable each of the Principal Stockholders to comply
with the foregoing. Parent shall complete and execute a resale or other
exemption certificate with respect to the inventory items sold hereunder, and
shall provide the Principal Stockholders with an executed copy thereof.

          SECTION 7.08. Section 338(g) Election. Parent may in its discretion
make an election under Code Section 338(g) and any comparable provisions of
state or local tax laws with respect to Parent's and the Company's purchase of
the Common Stock thereof (a "Section 338 Election"). Provided that Parent makes
a Section 338 Election, the deemed Merger Consideration for the Company's stock
shall be made in accordance with Code Sections 338 and 1060 and the Principal
Stockholders shall accept the Company's determinations of the Merger
Consideration allocations and shall report, act, and file Tax Returns in all
respects and for all purposes consistent with such determination of the Parent
and provide any and all assistance reasonably requested by Parent in connection
with effecting such Section 338 Election. Provided that Parent makes a Section
338 Election, Parent shall indemnify, defend, and hold harmless Principal
Stockholders from all liability for Taxes of the Company resulting from the
Section 338 Election for which Principal Stockholders may otherwise have
liability under this Agreement or applicable law.

          SECTION 7.09. Miscellaneous.

          (a) Each of the Principal Stockholders and Parent agree to treat all
payments made by either of them to or for the benefit of the other (including
any payments to the Company or any Subsidiary) under this Article VII, under
other indemnity provisions of this Agreement and for any misrepresentations or
breaches of warranties or covenants as adjustments to the Merger Consideration
or as capital contributions for Tax purposes, as applicable, and that such
treatment shall govern for purposes hereof except to the extent that the Laws of
a particular jurisdiction provide otherwise, in which case such payments shall
be made in an amount sufficient to indemnify the relevant party on an after-Tax
basis.

          (b) All payments payable under any tax sharing agreement or
arrangement between the Principal Stockholders and the Company or any Subsidiary
for any taxable period ending on or prior to the date of the Closing shall be
calculated on a basis consistent with past practice and shall be payable in full
prior to the Closing. Any and all tax sharing agreement or similar agreements
with respect to or involving the Company or any Subsidiary shall be terminated
as of the Closing Date and, after the Closing Date, neither Principal
Stockholders, Parent nor the Company or any Subsidiary shall be bound thereby or
have any liability thereunder.

          (c) Notwithstanding any provisions in this Agreement to the contrary,
the obligations of the Principal Stockholders to indemnify and hold harmless
Parent, the Company and the Subsidiaries pursuant to this Article VII, and the
representations and warranties contained in Section 3.28, shall terminate at the
close of business on the 90th day following the expiration of the applicable
statute of limitations with respect to the Tax liabilities in question (giving
effect to any waiver, mitigation or extension thereof).

          (d) From and after the date of this Agreement, the Principal
Stockholders shall not, without the prior written consent of Parent (which may,
in its sole and absolute discretion, withhold such consent), make, or cause or
permit to be made, any Tax election that would affect the Company or any
Subsidiary.

Article VII are intended to survive the Closing Date.

          SECTION 9.01. Survival of Representations and Warranties.

          (a) The representations and warranties of the Principal Stockholders
contained in this Agreement shall survive until thirty (30) months following the
Effective Time; provided, however, that (i) the representations and warranties

behalf of Parent. If written notice of a claim has been given prior to the
expiration of the applicable representations and warranties by Parent to the
Principal Stockholders, then the relevant representations and warranties shall
survive as to such claim, until such claim has been finally resolved.

          (b) The representation and warranties of Parent contained in this

          (c) All covenants in this Agreement shall survive the Closing until
fully performed in accordance with their terms.

          SECTION 9.02. Indemnification by the Principal Stockholders. Subject
to Section 9.04, Parent and its Affiliates (including, after the Closing Date,
the Surviving Corporation), officers, directors, employees, agents, successors
and assigns (each a "Parent Indemnified Party") shall be indemnified and held
harmless by the Principal Stockholders from and against any and all Liabilities,
losses, diminution in value, damages, claims, costs and expenses, interest,
awards, judgments and penalties (including attorneys' and consultants' fees and
expenses) actually suffered or incurred by them (including any Action brought or
otherwise initiated by any of them) (hereinafter a "Loss"), arising out of or
resulting from:

               (i) the breach of any representation or warranty made by the
          Company or the Principal Stockholders contained in this Agreement;

               (ii) the breach of any covenant or agreement by the Principal
          Stockholders contained in the Acquisition Documents;

               (v) Any liabilities or obligations relating to or arising out of
          the items set forth in Section 9.02 of the Disclosure Schedule.

To the extent that the Principal Stockholders' undertakings set forth in this
Section 9.02 may be unenforceable, the Principal Stockholders shall contribute
the maximum amount that it is permitted to contribute under applicable Law to
the payment and satisfaction of all Losses incurred by the Parent Indemnified
Parties.

          SECTION 9.03. Indemnification by Parent. Subject to Section 9.04, the
Principal Stockholders and its Affiliates, officers, directors, employees,
agents, successors and assigns (each a "Seller Indemnified Party") shall be
indemnified and held harmless by Parent for and against any and all Losses,
arising out of or resulting from:

               (i) the breach of any representation or warranty made by Parent
          contained in this Agreement;

               (ii) the breach of any covenant or agreement by Parent contained
          in the Acquisition Documents; or

                                      -60-

<PAGE>

               (iii) any claim or cause of action of any third party to the
          extent arising out of any action, inaction, event, condition,
          liability or obligation of Parent (including Liabilities which arise
          out of or are related to the ownership and operation of the Surviving
          Corporation from and after the Closing Date).

To the extent that Parent's undertaking set forth in Section 9.03 may be
unenforceable, Parent shall contribute the maximum amount that it is permitted
to contribute under applicable Law to the payment and satisfaction of all Losses
incurred by the Seller Indemnified Party.

          SECTION 9.04. Limits on Indemnification. Notwithstanding anything to
the contrary contained in this Agreement, (x) except with respect to (i) Taxes
or (ii) claims relating to the intentional breach of any representation or
warranty or fraud, an Indemnifying Party shall not be liable for any claim for
indemnification pursuant to Section 9.02, unless and until the aggregate amount
of indemnifiable Losses which may be recovered from the Indemnifying Party
equals or exceeds $300,000; and (y) except with respect to claims relating to
(i) Taxes or (ii) the representation and warranties in Sections 3.01, 3.02 and
3.03, or (iii) the intentional breach of any representation or warranty or
fraud, the maximum amount of indemnifiable Losses which may be recovered from an
Indemnifying Party arising out of or resulting from the causes set forth in
Section 9.02 or 9.03, as the case may be, shall be an amount equal to 50% of the
Merger Consideration. For purposes of calculating Losses, any limitations or
qualifications as to "materiality" (including the words "material" or "Material
Adverse Effect") shall be disregarded, such that the entire amount of any Loss
arising from a breach of any representation or warranty so limited or qualified
as to "materiality" shall be used to calculate the aggregate amount of
indemnifiable Losses.

          SECTION 9.05. Notice of Loss; Third Party Claims.

          (a) An Indemnified Party shall give the Indemnifying Party notice of
any matter which an Indemnified Party has determined has given or could give
rise to a right of indemnification under this Agreement, promptly after such
determination (but in any event within five (5) Business Days after any event
giving rise to such indemnification), stating the amount of the Loss, if known,
and method of computation thereof, and containing a reference to the provisions
of this Agreement in respect of which such right of indemnification is claimed
or arises; provided, however, that no delay on the part of the Indemnified Party
in providing such notice shall relieve the Indemnifying Party of any liabilities
hereunder unless (and then only to the extent that) the Indemnifying Party is
damaged by such delay.

          (b) If an Indemnified Party shall receive notice of any Action, audit,
demand or assessment (each, a "Third Party Claim") against it or which may give
rise to a claim for Loss under this Article IX, within five (5) days of the
receipt of such notice, the Indemnified Party shall give the Indemnifying Party
notice of such Third Party Claim; provided, however, that the failure to provide
such notice shall not release the Indemnifying Party from any of its obligations
under this Article IX except to the extent that the Indemnifying Party is
materially prejudiced by such failure and shall not relieve the Indemnifying
Party from any other obligation or Liability that it may have to any Indemnified
Party otherwise than under this Article IX. If the Indemnifying Party
acknowledges in writing its obligation to indemnify the Indemnified Party
hereunder against any Losses that may result from such Third Party Claim, then
the

                                      -61-

<PAGE>

Indemnifying Party shall be entitled to assume and control the defense of such
Third Party Claim at its expense and through counsel of its choice if it gives
notice of its intention to do so to the Indemnified Party within thirty (30)
days of the receipt of such notice from the Indemnified Party (or, in the event
that the Principal Stockholders are the Indemnifying Party, such longer
reasonable period of time required by the carrier of the R&W Insurance Policy);
provided, however, that if there exists or is reasonably likely to exist a
conflict of interest that would make it inappropriate in the judgment of the
Indemnified Party in its sole and reasonable discretion for the same counsel to
represent both the Indemnified Party and the Indemnifying Party, then the
Indemnified Party shall be entitled to retain its own counsel in each
jurisdiction for which the Indemnified Party determines counsel is required, at
the expense of the Indemnifying Party; provided, further, that the Indemnifying
Party shall only be required to pay the reasonable fees of one separate legal
counsel of the Indemnified Party. In the event that the Indemnifying Party
exercises the right to undertake any such defense against any such Third Party
Claim as provided above, the Indemnified Party shall cooperate with the
Indemnifying Party in such defense and make available to the Indemnifying Party,
at the Indemnifying Party's expense, all witnesses, pertinent records, materials
and information in the Indemnified Party's possession or under the Indemnified
Party's control relating thereto as is reasonably required by the Indemnifying
Party. Similarly, in the event the Indemnified Party is, directly or indirectly,
conducting the defense against any such Third Party Claim, the Indemnifying
Party shall cooperate with the Indemnified Party in such defense and make
available to the Indemnified Party, at the Indemnifying Party's expense, all
such witnesses, records, materials and information in the Indemnifying Party's
possession or under the Indemnifying Party's control relating thereto as is
reasonably required by the Indemnified Party. No such Third Party Claim may be
settled by the Indemnifying Party without the prior written consent of the
Indemnified Party, unless such settlement is made only for monetary
consideration, and all required payments of such monetary consideration are paid
entirely by the Indemnifying Party.

          (c) Any amount finally determined to be owed by the Principal
Stockholders to the Parent Indemnified Parties in respect of clause (i) of
Section 9.02 (whether through completion of any dispute resolution process,
agreement of the parties, or otherwise) shall be payable within 45 days after
such determination.

          SECTION 9.06. Mitigation and Limitations. (a) Parent, Merger Sub, the
Company and the Principal Stockholders agree to use commercially reasonable
efforts to mitigate any Loss (including by good faith pursuit of insurance
recovery) which forms the basis of any claim for indemnification hereunder. All
Losses recoverable by an Indemnified Party shall be net of insurance proceeds
actually recovered by or on behalf of such Indemnified Party. If an Indemnifying
Party makes a payment in respect of Losses of an Indemnified Party, and if at
any time subsequent to such payment the amount of such Losses is reduced by
recovery, settlement, or otherwise under or pursuant to any insurance coverage,
or pursuant to any claim, recovery, settlement, or payment by or against any
other person or entity (excluding any taxing authority), the amount of such
reduction, less any costs, expenses, premiums, or taxes incurred in connection
therewith will promptly be repaid by the Indemnified Party to the Indemnifying
Party.

          SECTION 9.07. Insurance.

          (a) Parent shall cause the Surviving Corporation to maintain the
Company Insurance Policies, or insurance coverage that is substantially similar
thereto, for a period of not less than the applicable survival periods set forth
in 9.01(a).

          (b) In addition, the parties acknowledge and agree that the
Stockholders shall purchase, out of amounts reserved therefor in the Escrow
Account, for the benefit of the Principal Stockholders a policy of insurance
against Losses incurred by the Principal Stockholders hereunder in connection
with breaches of the representations made by the Principal Stockholders or the
Company hereunder, consistent with the Non-Binding Indication Letter attached
hereto as Exhibit 9.07 and in a form reasonably acceptable to Parent and the
Principal Stockholders, naming Parent and the Surviving Corporation as loss
payees, and directing payments of indemnifiable Losses (but not payments in
reimbursement of the Principal Stockholders in defending against indemnity
claims) be made to Parent (the "R&W Insurance Policy"). The Principal
Stockholders shall bear the cost of the R&W Insurance Policy to the extent such
premium is in excess of the amount set aside therefor in the Escrow Account.
Notwithstanding anything to the contrary in this Agreement, the Principal
Stockholders shall have no liability or obligation with respect to Taxes or
income or loss of Parent or the Surviving Corporation arising out of the status
of Parent or the Surviving Corporation as a loss payee.

          SECTION 9.08. Exclusive Remedy (a) Parent, Merger Sub, the Company and
the Principal Stockholders agree that, from and after the Closing Date, except
as expressly set forth in this Agreement, with respect to any breach or
violation (other than any willful, intentional or fraudulent breach or
violation) of any representation or warranty set forth in the Agreement, the
only relief available to the party indemnified for such breach in respect of
such breach shall be as set forth in this Article IX; provided, however, that
the foregoing limitation shall not apply to remedies of specific performance or
other injunctive relief in connection with a breach of the covenants contained
in Articles II, V, VII and IX.

                                    ARTICLE X

                        TERMINATION, AMENDMENT AND WAIVER

          SECTION 10.01. Termination. This Agreement may be terminated at any
time prior to the Closing:

          (a) by Parent if, between the date hereof and the Closing Date: (i) an
event or condition occurs that has resulted in a Material Adverse Effect, (ii)
any representations and warranties of the Company or the Principal Stockholders
contained in this Agreement (1) that are not qualified by "materiality" shall
not have been true and correct in all material respects when made or (2) that
are qualified by "materiality" shall not have been true and correct when made,
(iii) the Company or the Principal Stockholders shall not have complied in all
material respects with the covenants or agreements contained in this Agreement
to be complied with by it prior to the time required for such compliance, or
(iv) the Company or any Subsidiary makes a general assignment for the benefit of
creditors, or any proceeding shall be instituted by or against the Company or
any Subsidiary seeking to adjudicate any of them a bankrupt or insolvent, or
seeking liquidation, winding up or reorganization, arrangement, adjustment,
protection, relief or

composition of its debts under any Law relating to bankruptcy, insolvency or
reorganization;

          (b) by either the Principal Stockholders or the Company if, between

Parent contained in this Agreement shall not have been true and correct in all
material respects when made, (ii) Parent or Merger Sub shall not have complied
in all material respects with the covenants or agreements contained in this
Agreement to be complied with by it prior to the time required for such
compliance, or (iii) the Parent makes a general assignment for the benefit of

adjudicate it a bankrupt or insolvent, or seeking liquidation, winding up or
reorganization, arrangement, adjustment, protection, relief or composition of
its debts under any Law relating to bankruptcy, insolvency or reorganization;

          (c) by either the Principal Stockholders, the Company, Parent or
Merger Sub if the Closing shall not have occurred by November 28, 2006;
provided, however, that the right to terminate this Agreement under this Section
10.01(c) shall not be available to any party whose failure to fulfill any
obligation under this Agreement shall have been the cause of, or shall have
resulted in, the failure of the Effective Time to occur on or prior to such
date;

          (d) by either Parent or the Company in the event that any Governmental
Authority shall have issued an order, decree or ruling or taken any other action
restraining, enjoining or otherwise prohibiting the transactions contemplated by
this Agreement and such order, decree, ruling or other action shall have become
final and nonappealable; or

          (e) by the mutual written consent of the Company, the Principal
Stockholders and Parent.

          SECTION 10.02. Effect of Termination. In the event of termination of
this Agreement as provided in Section 10.01, this Agreement shall forthwith
become void and there shall be no liability on the part of either party hereto
except (a) as set forth in Sections 5.03 and 11.01 and (b) that nothing herein
shall relieve either party hereto from liability for any breach of this
Agreement. In the event of termination of this Agreement as provided in clauses
(i), (ii) or (iii) of Section 10.01(a), the Company shall promptly return the
Good Faith Deposit to Parent. In the event of termination of this Agreement
under any other circumstances, the Company shall be entitled to keep the Good
Faith Deposit, and Parent shall reimburse the Company for its reasonable
"out-of-pocket expenses" (including without limitation the fees and expenses of
the Company's attorneys and accountants) related to the transactions
contemplated by this Agreement, including without limitation those incurred in
connection with the Pre-Effective Carve-out Transactions; provided that for the
sake of clarity, such "out of pocket expenses" shall include (but not be limited
to) the reasonable legal, accounting and tax fees incurred in connection with
the transactions contemplated by this Agreement, the non-refundable application
fee related to the R&W Insurance Policy application, the appraisal fee related
to the Pre-Effective Carve-out Transaction asset valuation, and construction or
remodeling costs incurred through July 31, 2006, in connection with the buildout
of the Life Plus administrative

not in any event include construction or remodeling costs in excess of $150,000,
construction or remodeling costs incurred from and after August 1, 2006, or

                                   ARTICLE XI

                               GENERAL PROVISIONS

          SECTION 11.01. Expenses. Except as otherwise specified in this
Agreement, all costs and expenses, including fees and disbursements of counsel,
financial advisors and accountants, incurred in connection with this Agreement

incurring such costs and expenses, whether or not the Merger shall have
occurred. The Principal Stockholders shall reimburse the Surviving Corporation
for such costs and expenses of the Company incurred in connection with this
Agreement and the Pre-Effective Carve-Out Transactions prior to and as of the
Closing Date to the extent such costs and expenses are in excess of the amounts
set aside therefor in the Escrow Account.

          SECTION 11.03. Public Announcements. None of the parties hereto shall
make, or cause to be made, any press release or public announcement in respect
of this Agreement or the transactions contemplated hereby or otherwise
communicate with any news media without the prior consent of the other party
unless otherwise required by Law or applicable stock exchange regulation.

          SECTION 11.04. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any Law or
public policy, all other terms and provisions of this Agreement shall
nevertheless remain in full force and effect for so long as the economic or
legal substance of the transactions contemplated hereby is not affected in any
manner materially adverse to either party hereto. Upon such determination that
any term or other provision is invalid, illegal or incapable of being enforced,
the parties hereto shall negotiate in good faith to modify this Agreement so as
to effect the original intent of the parties as closely as possible in an
acceptable manner in order that the transactions contemplated hereby are
consummated as originally contemplated to the greatest extent possible.

          SECTION 11.05. Entire Agreement. This Agreement and the Acquisition
Documents constitute the entire agreement of the parties hereto with respect to
the subject matter

                                      -66-

<PAGE>

hereof and thereof and supersede all prior agreements and undertakings
(including the Letter of Intent), both written and oral, among the Company, the
Principal Stockholders, Parent and Merger Sub with respect to the subject matter
hereof and thereof.

          SECTION 11.06. Assignment. This Agreement may not be assigned by
operation of law or otherwise without the express written consent of the Company
and the Parent (which consent may be granted or withheld in the sole discretion
of the Company or the Parent); provided, however, that the Parent may assign
this Agreement or any of its rights and obligations hereunder to one or more
Affiliates of the Parent without the consent of the Principal Stockholders, so
long as Parent remains primarily liable for all of its obligations hereunder;
and provided, further, that the Principal Stockholders may subrogate any claim
or assign any right under this Agreement to the extent it is required to do so
pursuant to the R&W Insurance Policy, so long as the Principal Stockholders
remain primarily liable for all of their obligations hereunder.

          SECTION 11.07. Amendment. This Agreement may not be amended or
modified except (a) by an instrument in writing signed by, or on behalf of, the
Company, the Principal Stockholders and Parent or (b) by a waiver in accordance
with Section 11.08.

          SECTION 11.08. Waiver. Either party to this Agreement may (a) extend
the time for the performance of any of the obligations or other acts of the
other party, (b) waive any inaccuracies in the representations and warranties of
the other party contained herein or in any document delivered by the other party
pursuant hereto or (c) waive compliance with any of the agreements of the other
party or conditions to such party's obligations contained herein. Any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed by the party to be bound thereby. Any waiver of any term or condition
shall not be construed as a waiver of any subsequent breach or a subsequent
waiver of the same term or condition, or a waiver of any other term or condition
of this Agreement. The failure of either party hereto to assert any of its
rights hereunder shall not constitute a waiver of any of such rights. All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

          SECTION 11.09. No Third Party Beneficiaries. Except for the provisions
of Article IX relating to indemnified parties and Sections 2.06, 2.07 and 2.08
relating to the rights of Stockholders, this Agreement shall be binding upon and
inure solely to the benefit of the parties hereto and their respective
successors and permitted assigns and nothing herein, express or implied, is
intended to or shall confer upon any other Person, including any union or any
employee or former employee of the Company, any legal or equitable right,
benefit or remedy of any nature whatsoever, including any rights of employment
for any specified period, under or by reason of this Agreement.

          SECTION 11.10. Specific Performance. Each of the Company and the
Principal Stockholders acknowledges and agrees that Parent would be irreparably
damaged if any of the provisions of this Agreement are not performed in
accordance with their specific terms and that any breach of this Agreement by
Parent could not be adequately compensated in all cases by monetary damages
alone. Accordingly, in addition to any other right or remedy to which Parent may
be entitled, at law or in equity, subject to Section 9.08 hereof, it shall be
entitled to enforce

                                      -67-

<PAGE>

and provision of this Agreement by a decree of specific performance and to
temporary, preliminary and permanent injunctive relief to prevent breaches or
threatened breaches of any of the provisions of this Agreement, without posting
any bond or other undertaking.

          SECTION 11.11. Governing Law. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Delaware applicable to
contracts executed in and to be performed in that State. Each of the parties
hereto irrevocably agrees that any litigation or dispute based hereon, or
arising out of, under, or in connection with the Acquisition Documents between
or among the parties hereto or thereto, shall be brought and maintained
exclusively in the federal and state courts located in the state of Delaware.
Each of the parties hereto hereby expressly and irrevocably submits to the
jurisdiction of such courts. Each of the parties hereto hereby expressly and
irrevocably waives, to the fullest extent permitted by law, any objection which
it may now or hereafter have to the laying of venue of any such litigation
brought in any such court referred to above and any claim that any such
litigation has been brought in an inconvenient forum.

          SECTION 11.12. Waiver of Jury Trial. Each of the parties hereto hereby
waives to the fullest extent permitted by applicable law any right it may have
to a trial by jury with respect to any litigation directly or indirectly arising
out of, under or in connection with this Agreement or the transactions
contemplated by this Agreement. Each of the parties hereto hereby (a) certifies
that no representative, agent or attorney of the other party has represented,
expressly or otherwise, that such other party would not, in the event of
litigation, seek to enforce the foregoing waiver and (b) acknowledges that it
has been induced to enter into this Agreement and the transactions contemplated
by this Agreement, as applicable, by, among other things, the mutual waivers and
certifications in this Section 11.12.

          SECTION 11.13. Counterparts. This Agreement may be executed and
delivered (including by facsimile transmission) in one or more counterparts, and
by the different parties hereto in separate counterparts, each of which when
executed shall be deemed to be an original, but all of which taken together
shall constitute one and the same agreement.
