Debtor has the requisite corporate power and authority to enter into this
Agreement and otherwise to carry out its obligations hereunder.  The
execution, delivery and performance by the Debtor of this Agreement and the
filings contemplated herein have been duly authorized by all necessary action on
the part of the Debtor and no further action is required by the
Debtor.  This Agreement constitutes a legal, valid and binding
obligation of the Debtor enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting the enforcement of creditor’s rights
generally.

         

        (b)           The
Debtor represents and warrants that it has no place of business or offices where
its respective books of account and records are kept (other than temporarily at
the offices of its attorneys or accountants) or places where Collateral is
stored or located, except as set forth on Schedule A attached
hereto.

         

        (c)           The
full legal name of the Debtor is as set forth on the signature page

hereto.


        
          
             


          

          
            5

            
              

            

          

          
             


          

        


        (d)         Without
limiting any prohibitions or restrictions in the Note, the Debtor shall not
change its name, identity, corporate structure (e.g., by merger,
consolidation, change in corporate form or otherwise), sole place of business,
chief executive office, type of organization or jurisdiction of organization or
establish any trade names unless it shall have (a) notified the Collateral Agent
in writing at least ten (10) days prior to any such change or establishment,
identifying such new proposed name, identity, corporate structure, sole place of
business, chief executive office, jurisdiction of organization or trade name and
providing such other information in connection therewith as the Collateral Agent
may reasonably request and (b) taken all actions reasonably necessary or
advisable to maintain the continuous validity, perfection and the same priority
of the Collateral Agent’s security interest in the Collateral intended to be
granted and agreed to hereby.

         

        (e)         Except
for Permitted Liens, the Debtor is the sole owner of the Collateral (except for
exclusive, semi-exclusive and non-exclusive licenses granted by a Debtor in the
ordinary course of business which licenses existing as of the date hereof are
identified on Schedule
E hereto), free and clear of any liens, security interests, encumbrances,
rights or claims, and, subject to the receipt of the consent of BIO-RAP under
the License Agreement, is fully authorized to grant the Security Interest in and
to pledge the Collateral.

         

        (f)          This
Agreement creates in favor of the Collateral Agent a valid security interest in
the Collateral securing the payment and performance of the Obligations and, upon
making the filings described in the immediately following sentence, a perfected
first priority security interest in such Collateral.  Except for the
filing of financing statements on Form-1 under the UCC with the Secretary of
State of the State of Delaware, no authorization or approval of or filing with
or notice to any governmental authority or regulatory body is required either
(i) for the grant by a Debtor of, or the effectiveness of, the Security Interest
granted hereby or for the execution, delivery and performance of this Agreement
by the Debtor or (ii) for the perfection of or exercise by the Collateral Agent
of its rights and remedies hereunder.

         

        (g)         Other
than Permitted Liens and Permitted Transfers, the Debtor will not transfer,
pledge, hypothecate, encumber, license, sell or otherwise dispose of any of the
Collateral without the prior written consent of the Collateral
Agent.  “Permitted Transfers” means (i) sales of inventory in the
normal course of business, (ii) licenses of technology in the ordinary course of
business on commercially reasonable terms and consistent with the Company's past
practices, (iii) dispositions of worn-out or obsolete equipment and dispositions
of equipment not exceeding $50,000 per year, (iv) certain amounts that may be
payable to JMP Securities LLC pursuant to the engagement letter dated November
18, 2008 in the event of the sale of all or substantially all of the Debtor’s
business, or (v) payment of certain amounts owed to unsecured creditors of the
Debtor, including approximately $475,000 in liabilities outstanding as of
December 31, 2008, and up to $3,199,955 in additional liabilities that are
anticipated to be incurred in the near term, including, without limitation,
operating expenses, severance payments, cost of tail policies relating to the
current directors’ and officers’ liability insurance policies maintained by the
Company on the date of this Agreement and other costs related to the winding-up
of the Company’s business; provided, however, that of the
amount to be paid in additional liabilities, $1,462,000 shall be reserved for
the payment of all costs related to the winding-up of the Company’s business and
$136,000 shall be paid to BIO-RAP, which represents all the payments due to
BIO-RAP under the License Agreement between BIO-RAP and the Company through
December 31, 2009.  The funds for the payment of such liabilities
shall first come from available cash on hand and second, from proceeds of the
sale or other liquidation of unencumbered assets, excluding the
Collateral.  The Collateral may not be sold to unsecured creditors and
the proceeds may not be used to pay any of the unsecured
creditors.

Debtor shall promptly execute (as applicable) and deliver to the Collateral
Agent such further assignments, security agreements, financing statements or
other instruments, documents, certificates and assurances and take such further
action as the Collateral Agent may from time to time reasonably request and may
reasonably deem necessary to perfect, protect or enforce its security interest

(ii) the registration of any Intellectual Property by any such
office.  The Debtor shall take such step as may be reasonably

respect to any such Collateral in existence on the date hereof, on or prior to
the date hereof and (ii) with respect to any such Collateral hereafter arising,
within ten (10) days of the Debtor acquiring rights therein.

         

        4.           Event of

Notes or otherwise, or of any check, draft, note, trade acceptance or other

for the Collateral Agent and shall forthwith endorse and transfer any such sums
or instruments, or both, to the Collateral Agent for application to the
satisfaction of the Obligations.

facilities for the purpose of the Collateral Agent taking possession of,
removing or putting the Collateral in saleable or disposable form.

         

        (b)           The
Collateral Agent shall have the right to operate the business of the Debtor
using the Collateral and shall have the right to assign, sell, lease or
otherwise dispose of and deliver all or any part of the Collateral, at public or
private sale or otherwise, either with or without special conditions or
stipulations, for cash or on credit or for future delivery, in such parcel or
parcels and at such time or times and at such place or places, and upon such
terms and conditions as the Collateral Agent may deem commercially reasonable,
all without (except as shall be required by applicable statute and cannot be
waived) advertisement or demand upon or notice to the Company or right of
redemption of the Company, which are hereby expressly waived.  Upon
each such sale, lease, assignment or other transfer of Collateral, the
Collateral Agent may, unless prohibited by applicable law which cannot be
waived, purchase all or any part of the Collateral being sold, free from and
discharged of all trusts, claims, right of redemption and equities of the
Company, which are hereby waived and released.

         

        7.           Applications of
Proceeds.  The proceeds of any such sale, lease or other
disposition of the Collateral hereunder shall be applied first, to the expenses
of retaking, holding, storing, processing and preparing for sale, selling, and
the like (including, without limitation, any taxes, fees and other costs
incurred in connection therewith) of the Collateral, to the reasonable
attorneys’ fees and expenses incurred by the Collateral Agent in enforcing its
rights hereunder and in connection with collecting, storing and disposing of the
Collateral, and then to satisfaction of the Obligations, and to the payment of
any other amounts required by applicable law, after which the Collateral Agent
shall pay to the Company any surplus proceeds.

         

        8.           Costs and
Expenses.  The Company agrees to pay all reasonable
out-of-pocket fees, costs and expenses incurred in connection with any filing
required hereunder, including without limitation, any financing statements,
continuation statements, partial releases and/or termination statements related
thereto.  The Company will also, upon demand, pay to the Collateral
Agent the amount of any and all reasonable expenses, including the reasonable
fees and expenses of its counsel, which the Collateral Agent may incur in
connection with (i) the enforcement of this Agreement or (ii) the custody or
preservation of, or the sale of, collection from, or other realization upon, any
of the Collateral.

        9.           Security Interest
Absolute.  All rights of the Collateral Agent and all
Obligations of the Debtor hereunder, shall be absolute and unconditional,
irrespective of: (a) any lack of validity or enforceability of this Agreement,
the Notes or any agreement entered into in connection with the foregoing, or any
portion hereof or thereof; (b) any change in the time, manner or place of
payment or performance of, or in any other term of, all or any of the
Obligations, or any other amendment or waiver of or any consent to any departure
from the Notes or any other agreement entered into in connection with the
foregoing; (c)  any exchange, release or nonperfection of any of the
Collateral, or any release or amendment or waiver of or consent to departure
from any other collateral for, or any guaranty, or any other security, for all
or any of the Obligations; (d) any action by the Collateral Agent to obtain,
adjust, settle and cancel in its sole discretion any insurance claims or matters
made or arising in connection with the Collateral; or (e) any other circumstance
which might otherwise constitute any legal or equitable defense available to the
Debtor, or a discharge of all or any part of the Security Interest granted
hereby.  The Debtor expressly waives presentment, protest, notice of
protest, demand, notice of nonpayment and demand for performance.  In
the event that at any time any transfer of any Collateral or any payment
received by the Collateral Agent hereunder shall be deemed by final order of a
court of competent jurisdiction to have been a voidable preference or fraudulent
conveyance under the bankruptcy or insolvency laws of the United States, or
shall be deemed to be otherwise due to any party other than the Collateral
Agent, then, in any such event, the Debtor’s obligations hereunder shall survive
cancellation of this Agreement, and shall not be discharged or satisfied by any
prior payment thereof and/or cancellation of this Agreement, but shall remain a
valid and binding obligation enforceable in accordance with the terms and
provisions hereof.  The Debtor waives all right to require the
Collateral Agent to proceed against any other person or to apply any Collateral
which the Collateral Agent may hold at any time, or to marshal assets, or to
pursue any other remedy.  The Debtor waives any defense arising by
reason of the application of the statute of limitations to any obligation
secured hereby.

         

        10.         Power of
Attorney.  The Debtor hereby irrevocably appoints the
Collateral Agent (such appointment being coupled with an interest) as the
Debtor’s attorney-in-fact, with full authority in the place and stead of the
Debtor and in the name of the Debtor, the Collateral Agent or otherwise, from
time to time upon the occurrence and during the continuance of any Event of
Default in the Collateral Agent’s discretion to take any action and to execute
any instrument that the Collateral Agent may deem reasonably necessary or
advisable to accomplish the purposes of this Agreement.

         

        11.         Access; Right of
Inspection.  The Collateral Agent shall at all times have full
and free access during normal business hours following reasonable advance notice
to all the books, correspondence and records of the Debtor, and the Collateral
Agent and its representatives may examine the same, take extracts therefrom and
make photocopies thereof, and the Debtor agrees to render to the Collateral
Agent, at the Debtor's cost and expense, such clerical and other assistance as
may be reasonably requested with regard thereto.  The Collateral Agent
and its representatives shall at all times also have the right to enter any
premises of the Debtor and inspect any property of the Debtor where any of the
Collateral of the Debtor granted pursuant to this Agreement is located for the
purpose of inspecting the same, observing its use or otherwise protecting its
interests therein.

        12.           Further
Assurances.  The Debtor agrees that from time to time, at its
expense, that it shall promptly execute and deliver all further instruments and
documents, and take all further action, that may be necessary or desirable, or
that the Collateral Agent may reasonably request, in order to create and/or
maintain the validity, perfection or priority of and protect any security
interest granted hereby or to enable the Collateral Agent to exercise and
enforce its rights and remedies hereunder with respect to any
Collateral.

         

        13.           Term of
Agreement.  This Agreement and the Security Interest shall
terminate on the date on which all payments under the Notes have been made in
full.  Upon such termination, the Collateral Agent will promptly file
all termination statements with respect to any financing statement executed and
filed pursuant to this Agreement.

         

        14.           Notices.  All
notices, requests, demands and other communications hereunder shall be in
writing and shall be sent in accordance with the provision of Section 9 of the
Purchase Agreement.

         

        15.           Miscellaneous.

         

          (a)           No
course of dealing between the Debtor and the Collateral Agent, nor any failure
to exercise, nor any delay in exercising, on the part of the Collateral Agent,
any right, power or privilege hereunder or under the Notes shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder or thereunder preclude any other or further exercise thereof
or the exercise of any other right, power or privilege.

         

         
(b)           All
of the rights and remedies of the Collateral Agent with respect to the
Collateral, whether established hereby or by the Notes or by any other
agreements, instruments or documents or by law shall be cumulative and may be
exercised singly or concurrently.

         

          (c)           This
Agreement constitutes the entire agreement of the parties with respect to the
subject matter hereof and is intended to supersede all prior negotiations,
understandings and agreements with respect thereto.  Except as
specifically set forth in this Agreement, no provision of this Agreement may be
modified or amended except by a written agreement specifically referring to this
Agreement and signed by the parties hereto.

         

         
(d)           In
the event that any provision of this Agreement is held to be invalid, prohibited
or unenforceable in any jurisdiction for any reason, unless such provision is
narrowed by judicial construction, this Agreement shall, as to such
jurisdiction, be construed as if such invalid, prohibited or unenforceable
provision had been more narrowly drawn so as not to be invalid, prohibited or
unenforceable.  If, notwithstanding the foregoing, any provision of
this Agreement is held to be invalid, prohibited or unenforceable in any
jurisdiction, such provision, as to such jurisdiction, shall be ineffective to
the extent of such invalidity, prohibition or unenforceability without
invalidating the remaining portion of such provision or the other provisions of
this Agreement and without affecting the validity or enforceability of such
provision or the other provisions of this Agreement in any other
jurisdiction.

         

          (e)           No
waiver of any breach or default or any right under this Agreement shall be
considered valid unless in writing and signed by the party giving such waiver,
and no such waiver shall be deemed a waiver of any subsequent breach or default
or right, whether of the same or similar nature or otherwise.

        (f)          This
Agreement shall be binding upon and inure to the benefit of each party hereto
and its successors and assigns.

         

        (g)         This
Agreement shall be construed in accordance with the laws of the State of New
York, except to the extent the validity, perfection or enforcement of a security
interest hereunder in respect of any particular Collateral which are pursuant to
mandatory choice of law rules governed by a jurisdiction other than the State of
New York in which case such law shall govern.

         

        (h)         This
Agreement may be executed in any number of counterparts, each of which when so
executed shall be deemed to be an original, and all of which taken together
shall constitute one and the same Agreement.  In the event that any
signature is delivered by facsimile transmission, such signature shall create a
valid binding obligation of the party executing (or on whose behalf such
signature is executed) the same with the same force and effect as if such
facsimile signature were the original thereof.

         

        (i)           To
the fullest extent permitted by applicable law, the Debtor shall remain
obligated hereunder notwithstanding that, any demand for payment of any of the
Obligations made by any Secured Party may be rescinded by such Secured Party and
any of the Obligations continued, and the Obligations or any collateral security
or guarantee therefor or right of offset with respect thereto, may, from time to
time, in whole or in part, be renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released by the Collateral Agent or any
Secured Party, and the Note and/or Purchase Agreement and any other documents
executed and delivered in connection therewith may be amended, modified,
supplemented or terminated, in whole or in part, as the Collateral Agent (or the
requisite Holders) may deem advisable from time to time, and any collateral
security, guarantee or right of offset at any time held by any Secured Party for
the payment of the Obligations may be sold, exchanged, waived, surrendered or
released.
