of Default, to transfer any Collateral into the name of the Collateral Agent and
to take any and all action deemed  advisable to the  Collateral  Agent to remove
any transfer restrictions affecting the Collateral.

4.   Perfection of Security Interest.

     Artera shall execute and deliver to the  Collateral  Agent UCC-1  Financing
Statements  and other forms of  financing  statements  ("Financing  Statements")
relating to the security  interests in Artera's right, title and interest in and
to the  Collateral.  The  Collateral  Agent is  instructed to file the Financing
Statements at the Debtor's expense, in the following jurisdictions: State of New
York, New York County, Delaware,  Connecticut, New Haven County, Connecticut and
Fairfield  County,  Connecticut,  and any other  jurisdiction  including  local,
state,  national and international,  deemed advisable to Collateral Agent. These
Financing  Statements  are  deemed to have been  filed  for the  benefit  of the
Lenders identified on Schedule A hereto.  Upon satisfaction and discharge of all
of the Notes held by a particular  Lender, the Collateral Agent is instructed to
file a UCC-3 Termination  Statement with respect to such Lender, at the Debtor's
expense,  in all  jurisdictions  in which a Financing  Statement with respect to
such Lender is then on file.

5.   Distribution on Liquidation.

     5.1 If any sum is paid as a liquidating  distribution on or with respect to
the Collateral,  Debtor shall deliver same to the Collateral Agent to be applied
to the Obligations then due, in accordance with the terms of the Notes.

     5.2 Prior to any Event of Default  (as  defined  herein),  Debtor  shall be
entitled to  exercise  all voting  power  pertaining  to any of the  Collateral,
provided  such exercise is not contrary to the interests of the Lenders and does
not impair the Collateral, or the security interest granted the Lenders hereby.

6.   Further Action By Debtor; Covenants and Warranties.

     6.1 Collateral Agent at all times shall have a perfected  security interest
in the Collateral. Subject to the security interest described herein, Artera has
and will  continue  to have full  title to the  Collateral  free from any liens,
leases,  encumbrances,  judgments or other claims.  Collateral  Agent's security
interest in the Collateral  constitutes and will continue to constitute a first,
prior and indefeasible  security interest in favor of Collateral  Agent.  Debtor
will do all  acts  and  things,  and  will  execute  and  file  all  instruments
(including,  but not  limited to,  security  agreements,  financing  statements,
continuation  statements,  etc.)  reasonably  requested by  Collateral  Agent to
establish,  maintain and continue the perfected  security interest of Collateral
Agent in the Collateral, and will promptly on demand, pay all costs and expenses
of filing and recording,  including the costs of any searches  reasonably deemed
necessary by  Collateral  Agent from time to time to establish and determine the
validity  and the  continuing  priority of the security  interest of  Collateral
Agent,  and also pay all other  claims  and  charges  that,  in the  opinion  of
Collateral  Agent,  exercised in good faith, is reasonably  likely to materially
prejudice,  imperil or otherwise affect the Collateral or its security  interest
therein.

     6.2  Other  than  in the  ordinary  course  of  business,  and  except  for
Collateral which has become obsolete or is of inconsequential  in value,  Artera
will not sell,  transfer,  assign or pledge those items of Collateral  (or allow
any such items to be sold, transferred,  assigned or pledged), without the prior
written consent of Collateral Agent. Although Proceeds of Collateral are covered
by this Security Agreement,  this shall not be construed to mean that Collateral
Agent consents to any sale of the Collateral, except as provided herein.

     6.3 Debtor will, at all reasonable  times,  allow  Collateral  Agent or its
representatives  free and complete  access to all of Debtor 's records  which in
any way  relate  to the  Collateral,  for such  inspection  and  examination  as
Collateral Agent reasonably deems necessary.

     6.4  Debtor,  at its sole cost and  expense,  will  protect and defend this
Security  Agreement,  all of the rights of Collateral Agent  hereunder,  and the
Collateral against the claims and demands of all other parties.

     6.5 Debtor will promptly notify Collateral Agent of any levy,  distraint or
other seizure by legal process or otherwise of any part of the  Collateral,  and
of any threatened or filed claims or proceedings  that are reasonably  likely to
affect or impair  any of the rights of  Collateral  Agent  under  this  Security
Agreement.

     6.6 Debtor, at its own expense, will obtain and maintain in force insurance
policies covering losses or damage to those items of Collateral which constitute
physical  personal  property.  The  insurance  policies to be obtained by Debtor
shall be in form and amounts reasonably  acceptable to Collateral Agent.  Debtor
shall  make the  Collateral  Agent a loss  payee  thereon  to the  extent of its
interest. Collateral Agent is hereby irrevocably (until the Obligations are paid
in full) appointed Debtor's  attorney-in-fact to endorse any check or draft that
may be payable  to Debtor so that  Collateral  Agent may  collect  the  proceeds
payable for any loss under such insurance. The proceeds of such insurance,  less
any costs and expenses  incurred or paid by Collateral  Agent in the  collection
thereof, shall be applied either toward the cost of the repair or replacement of
the items  damaged  or  destroyed,  or on account  of any sums  secured  hereby,
whether  or not then due or  payable.  Insurance  will not be  required  for the
Security Shares.

     6.7 Collateral  Agent may, at its option,  and without any obligation to do
so,  pay,  perform  and  discharge  any and all  amounts,  costs,  expenses  and
liabilities  herein  agreed to be paid or  performed  by Debtor,  upon  Debtor's
failure to do so, and all amounts expended by Collateral Agent in so doing shall
become part of the Obligations  secured hereby, and shall be immediately due and
payable by Debtor to Collateral Agent upon demand and shall bear interest at 14%
per annum from the dates of such expenditures until paid.

     6.8 Upon the request of Collateral  Agent,  Debtor will furnish within five
(5) days  thereafter to Collateral  Agent,  or to any proposed  assignee of this
Security  Agreement,  a written  statement in form  reasonably  satisfactory  to
Collateral Agent, duly acknowledged,  certifying the amount of the principal and
interest then owing under the Obligations,  whether to its knowledge any claims,
offsets or defenses  exist  against the  Obligations  or against  this  Security
Agreement,  or any of the terms and provisions of any other  agreement of Debtor
securing the Obligations.  In connection with any assignment by Collateral Agent
of this Security Agreement, Debtor hereby agrees to cause the insurance policies
required  hereby  to be  carried  by  Debtor,  if any,  to be  endorsed  in form
satisfactory to Collateral Agent or to such assignee,  with loss payable clauses
in favor of such  assignee,  and to cause such  endorsements  to be delivered to
Collateral  Agent  within ten (10)  calendar  days  after  request  therefor  by
Collateral Agent.

     6.9  The  Debtor  will,  at  its  own  expense,  make,  execute,   endorse,
acknowledge,  file and/or deliver to the Collateral Agent from time to time such
vouchers, invoices, schedules, confirmatory assignments,  conveyances, financing
statements, transfer endorsements, powers of attorney, certificates, reports and
other  assurances  or  instruments  and  take  further  steps  relating  to  the
Collateral and other property or rights covered by the security  interest hereby
granted,  as the Collateral Agent may reasonably require to perfect its security
interest hereunder.

     6.10  Artera  represents  and  warrants  that  it is the  true  and  lawful
exclusive owner of the Collateral, free and clear of any liens and encumbrances.

     6.11 Debtor hereby  agrees not to directly or  indirectly  divest itself of
any right under the Collateral  absent prior written  approval of the Collateral
Agent except in the ordinary  course of business.  Debtor  further agrees to not
take any  action  or suffer  any  action  which  would  impair  the value of the
Collateral or  negatively  impact the security  interest of the Lenders  granted
hereby.

7.   Power of Attorney.

     Debtor hereby irrevocably  constitutes and appoints the Collateral Agent as
the true and lawful attorney of Debtor, with full power of substitution,  in the
place and stead of Debtor and in the name of Debtor or otherwise, at any time or
times,  in the  discretion of the  Collateral  Agent,  to take any action and to
execute any instrument or document which the Collateral Agent may deem necessary
or advisable to accomplish the purposes of this Agreement  which Debtor fails to
take or fails to execute within five (5) business days of the Collateral Agent's
reasonable  written request therefor.  This power of attorney is coupled with an
interest and is irrevocable.

8.   Performance By The Collateral Agent.

     If Debtor  fails to  perform  any  material  covenant,  agreement,  duty or
obligation of Debtor under this Agreement,  the Collateral  Agent may, after any
applicable cure period,  at any time or times in its discretion,  take action to
effect performance of such obligation. All reasonable expenses of the Collateral
Agent incurred in connection with the foregoing  authorization  shall be payable
by Debtor as provided in Paragraph 12.1 hereof. No discretionary  right,  remedy
or power granted to the Collateral  Agent under any part of this Agreement shall
be deemed to impose  any  obligation  whatsoever  on the  Collateral  Agent with
respect  thereto,  such  rights,  remedies  and  powers  being  solely  for  the
protection of the Collateral Agent.

9.   Event of Default.

     An event of default  ("Event of Default")  shall be deemed to have occurred
hereunder upon the occurrence of any event of default as defined in the Notes or
Subscription  Documents.  Upon  and  after  any  Event  of  Default,  after  the
applicable  cure  period,  if any,  any or all of the  Obligations  shall become
immediately  due and  payable at the  option of the  Collateral  Agent,  for the
benefit of the Lenders,  and the  Collateral  Agent may dispose of Collateral as
provided below. A default by Debtor of any of its  obligations  pursuant to this
Agreement shall be deemed an Event of Default  hereunder and an event of default
as defined in the Obligations. Without limiting the foregoing, failure to pay to
the  Collateral  Agent any sum due hereunder from the Debtor within five days of
demand shall be an Event of Default.

10.  Disposition of Collateral.

     Upon and after any Event of Default which is then continuing,

     10.1 The Collateral  Agent may exercise its rights with respect to each and
every component of the Collateral,  without regard to the existence of any other
security or source of payment for the  Obligations.  In addition to other rights
and remedies  provided for herein or otherwise  available to it, the  Collateral
Agent shall have all of the rights and remedies of a lender on default under the
Uniform Commercial Code then in effect in the State of New York.

     10.2 If any notice to Debtor of the sale or other disposition of Collateral
is required by then  applicable law, five (5) days' prior notice (or, if longer,
the shortest  period of time permitted by then  applicable law) to Debtor 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,  shall constitute
reasonable notification.

     10.3  The  Collateral  Agent  is  authorized,  at  any  such  sale,  if the
Collateral  Agent  deems it  advisable  to do so,  in order to  comply  with any
applicable securities laws, to restrict the prospective bidders or purchasers to
persons  who will  represent  and  agree,  among  other  things,  that  they are
purchasing the Collateral for their own account for  investment,  and not with a
view to the  distribution or resale thereof,  or otherwise to restrict such sale
in such other  manner as the  Collateral  Agent deems  advisable  to ensure such
compliance. Sales made subject to such restrictions shall be deemed to have been
made in a commercially reasonable manner.

         10.4 All cash proceeds received by the Collateral Agent for the benefit
of the Lenders in respect of any sale, collection or other enforcement or
disposition of Collateral, shall be applied (after deduction of any amounts
payable to the Collateral Agent pursuant to Paragraph 12.1 hereof) against the
Obligations pro rata among the Lenders in proportion to their interests in the
Obligations. Upon payment in full of all Obligations, Debtor shall be entitled
to the return of all Collateral, including cash, which has not been used or
applied toward the payment of Obligations or used or applied to any and all
costs or expenses of the Collateral Agent incurred in connection with the
liquidation of the Collateral (unless another person is legally entitled
thereto). Any assignment of Collateral by the Collateral Agent to Debtor shall
be without representation or warranty of any nature whatsoever and wholly
without recourse. Each Lender may purchase the Collateral and pay for such
purchase by offsetting any sums owed to such Lender by Debtor arising under the
Obligations or any other source.

     10.5 The Collateral,  if any, is so available after  application to satisfy
the  Obligations  and any other sums due  hereunder,  shall be  released  to the
Debtor upon the complete satisfaction of the Obligations.

     11.  Waiver of  Automatic  Stay.  The Debtor  acknowledges  and agrees that
should a proceeding  under any  bankruptcy or insolvency  law be commenced by or
against the Debtor,  or if any of the  Collateral  (as defined in this  Security
Agreement) should become the subject of any bankruptcy or insolvency proceeding,
then the Collateral Agent should be entitled to, among other relief to which the
Collateral Agent may be entitled under the Subscription  Documents and any other
agreement  to which  the  Debtor,  Lenders  or  Collateral  Agent  are  parties,
(collectively  "Loan Documents")  and/or applicable law, an order from the court
granting immediate relief from the automatic stay pursuant to 11 U.S.C.  Section
362 to permit the  Collateral  Agent to exercise  all of its rights and remedies
pursuant to the Loan Documents and/or applicable law. THE DEBTOR EXPRESSLY WAIVE
THE BENEFIT OF THE AUTOMATIC STAY IMPOSED BY 11 U.S.C. SECTION 362. FURTHERMORE,
THE DEBTOR EXPRESSLY  ACKNOWLEDGES AND AGREES THAT NEITHER 11 U.S.C. SECTION 362
NOR  ANY  OTHER  SECTION  OF THE  BANKRUPTCY  CODE  OR  OTHER  STATUTE  OR  RULE
(INCLUDING,  WITHOUT LIMITATION,  11 U.S.C. SECTION 105) SHALL STAY,  INTERDICT,
CONDITION,  REDUCE OR INHIBIT IN ANY WAY THE ABILITY OF THE COLLATERAL  AGENT TO
ENFORCE  ANY  OF ITS  RIGHTS  AND  REMEDIES  UNDER  THE  LOAN  DOCUMENTS  AND/OR
APPLICABLE  LAW. The Debtor  hereby  consents to any motion for relief from stay
which  may be filed by the  Collateral  Agent in any  bankruptcy  or  insolvency
proceeding  initiated by or against the Debtor,  and further  agrees not to file
any opposition to any motion for relief from stay filed by the Collateral Agent.
The Debtor represents, acknowledges and agrees that this provision is a specific
and material aspect of this Agreement,  and that the Collateral  Agent would not
agree to the  terms of this  Agreement  if this  waiver  were not a part of this
Agreement.  The Debtor  further  represents,  acknowledges  and agrees that this
waiver is  knowingly,  intelligently  and  voluntarily  made,  that  neither the
Collateral  Agent nor any person  acting on behalf of the  Collateral  Agent has
made any  representations  to  induce  this  waiver,  that the  Debtor  has been
represented  (or has had the  opportunity to be  represented)  in the signing of
this  Agreement  and in the making of this waiver by  independent  legal counsel
selected  by the Debtor and that the Debtor has had the  opportunity  to discuss
this waiver with counsel.

12.  Miscellaneous.

     12.1 Expenses.  Debtor shall pay to the Collateral  Agent,  on demand,  the
amount  of any and  all  reasonable  expenses,  including,  without  limitation,
attorneys'  fees,  legal expenses and brokers' fees,  which the Collateral Agent
may  incur in  connection  with (a) sale,  collection  or other  enforcement  or
disposition  of  Collateral;  (b)  exercise  or  enforcement  of any the rights,
remedies or powers of the Collateral  Agent  hereunder or with respect to any or
all of the  Obligations;  or (c)  failure by Debtor to perform  and  observe any
agreements  of Debtor  contained  herein which are  performed by the  Collateral
Agent.

     12.2  Waivers,  Amendment  and  Remedies.  No  course  of  dealing  by  the
Collateral Agent and no failure by the Collateral Agent to exercise, or delay by
the Collateral Agent in exercising,  any right,  remedy or power hereunder shall
operate as a waiver  thereof,  and no single or partial  exercise  thereof shall
preclude  any other or further  exercise  thereof or the  exercise  of any other
right,  remedy or power of the Collateral  Agent. No amendment,  modification or
waiver of any  provision of this  Agreement  and no consent to any  departure by
Debtor  therefrom,  shall,  in any event,  be  effective  unless  contained in a
writing signed by the Collateral Agent, and then such waiver or consent shall be
effective only in the specific  instance and for the specific  purpose for which
given.  The  rights,  remedies  and  powers of the  Collateral  Agent,  not only
hereunder,  but also under any instruments and agreements evidencing or securing
the Obligations and under applicable law are cumulative, and may be exercised by
the Collateral Agent from time to time in such order as the Collateral Agent may
elect.
