      WARRANTY AS TO THE QUALITY, SUITABILITY, OR ADEQUACY OF THE SERVICES OR
      PRODUCTS FOR ANY PURPOSE OR USE.



      IN NO EVENT SHALL TRANSTECH HAVE ANY LIABILITY UNDER THIS AGREEMENT OR
      OTHERWISE ARISING OUT OF OR RESULTING FROM THE PERFORMANCE OR FAILURE TO
      PERFORM, SERVICES FOR LOSS OF ANTICIPATED PROFITS, OR FOR ANY INCIDENTAL,

      Studies listed in Exhibit B.

4.3   SIGA has full responsibility for all business, financial and other

      costs and expenses of any kind and nature (including, without limitation,
      reasonable attorneys fees and court costs), incurred in connection with
      any claim, demand, proceeding, action, hearing or investigation (a
      "Claim") relating to or arising from the Agreement or the services
      performed by TransTech under the Agreement, except to the extent that: (i)
      such liability arises from the gross negligence or intentional misconduct
      of TransTech; or (ii) such Claim is made by an employee of TransTech
      arising from work performed by such employee in connection with this
      Agreement.

5.    CONFIDENTIALITY
      ---------------

      reports are the confidential and proprietary information of SIGA (the

      of its employees requiring such access in order to perform the Studies,
      inform such employees of the proprietary nature of the SIGA Information,

      by TransTech to protect its own proprietary information, to ensure that
      such employees observe the confidentiality obligations of TransTech
      hereunder.

5.4   The SIGA Information is and shall remain the property of SIGA and may be

      (a)   information which at the time of disclosure is in the public domain;
            provided that, specific information disclosed as part of the SIGA
            Information shall not be deemed to be in the public domain merely
            because it is embraced by more general information in the public
            domain; or

      (b)   information which, after disclosure, becomes part of the public
            domain by publication or otherwise, except by breach of this
            Agreement by TransTech or by any of TransTech's employees; or

      (c)   information which TransTech shall receive from a third party who has

            indirectly, from SIGA under a confidentiality agreement with SIGA;
            or

      (d)   information that is independently developed by TransTech without
            reference to the SIGA Information.

5.7   The provisions of this section shall survive the expiry or termination of
      this Agreement.

6.    TERM AND TERMINATION

      party without the prior written consent of the other party.

7.2   This Agreement shall be governed by the laws of the State of New York
      without regard to the principles of conflict-of-law doctrines of New York
      or any other jurisdiction. Any action or proceeding brought by either
      party against the other shall be brought in a state or federal court
      located in New York.

7.3   This Agreement contains the entire agreement between the parties and
      supersedes all prior agreements, written or oral, with respect to the
      subject matter hereof.

7.4   TransTech's completion of the Studies or successful search for third
      parties to complete the Studies required for SIGA's SIGA-246 IND
      submission does not obligate SIGA to use TransTech for any subsequent
      services, whether related to SIGA-246 or any other SIGA compound.



7.5   This Agreement shall not be amended, modified, varied or supplemented
      except in writing signed by duly authorized representatives of both
      parties.

7.6   No failure or delay on the part of either party hereto to exercise any
      right or remedy under this Agreement shall be construed or operated as a
      waiver thereof nor shall any single or partial exercise of any right or

      remedy or preclude the further exercise of such right or remedy as the
      case may be. The rights and remedies provided in this Agreement are
      cumulative and are not exclusive of any rights or remedies provided by
      law.

7.7   The parties do not intend that any agency or partnership relationship be
      created between them by this Agreement. The parties shall be and shall act
      at all times as independent contractors, and at no time shall either party
      make any commitments or incur any charges or expenses for or in the name
      of the other party.

      under this Agreement if such failure is occasioned by a contingency beyond
      such party's reasonable control, including but not limited to strikes or
      labor disturbances, lockouts, riots, wars, terrorist activities, fires,
      floods, earthquakes, storms or inability to obtain materials or services.

date first above written.

maintenance and repair), (ii) remove any of the Collateral from the continental
United States, or (iii) sell, rent, lease, mortgage, license, grant a security
interest in or otherwise transfer or encumber (except for Permitted Liens) any
of the Collateral.

      (d) Debtor shall pay promptly when due all taxes, license fees,
assessments and public and private charges levied or assessed on any of the
Collateral, on its use, or on this Agreement or any of the other Debt Documents.
At its option, Secured Party may discharge taxes, liens, security interests or
other encumbrances at any time levied or placed on the Collateral and may pay
for the maintenance, insurance and preservation of the Collateral and effect
compliance with the terms of this Agreement or any of the other Debt Documents.
Debtor agrees to reimburse Secured Party, on demand, all costs and expenses
incurred by Secured Party in connection with such payment or performance and
agrees that such reimbursement obligation shall constitute Indebtedness.

      (e) Debtor shall, at all times, keep accurate and complete records of the
Collateral, and Secured Party shall have the right to inspect and make copies of
all of Debtor's books and records relating to the Collateral during normal
business hours, after giving Debtor reasonable prior notice.

      (f) Debtor agrees and acknowledges that any third person who may at any
time possess all or any portion of the Collateral shall be deemed to hold, and
shall hold, the Collateral as the agent of, and as pledge holder for, Secured
Party. Secured Party may at any time give notice to any third person described
in the preceding sentence that such third person is holding the Collateral as
the agent of, and as pledge holder for, the Secured Party.

4.    INSURANCE.

      (a) Debtor shall at all times bear the entire risk of any loss, theft,
damage to, or destruction of, any of the Collateral from any cause whatsoever.



      (b) Debtor agrees to keep the Collateral insured against loss or damage by
fire and extended coverage perils, theft, burglary, and for any or all
Collateral which are vehicles, for risk of loss by collision, and if requested
by Secured Party, against such other risks as Secured Party may reasonably
require. The insurance coverage shall be in an amount no less than the full
replacement value of the Collateral, and deductible amounts, insurers and
policies shall be acceptable to Secured Party. Debtor shall deliver to Secured
Party policies or certificates of insurance evidencing such coverage. Each
policy shall name Secured Party as a loss payee, shall provide for coverage to
Secured Party regardless of the breach by Debtor of any warranty or
representation made therein, shall not be subject to co-insurance, and shall
provide that coverage may not be canceled or altered by the insurer except upon
thirty (30) days prior written notice to Secured Party. Debtor appoints Secured
Party as its attorney-in-fact to make proof of loss, claim for insurance and
adjustments with insurers, and to receive payment of and execute or endorse all
documents, checks or drafts in connection with insurance payments. Secured Party
shall not act as Debtor's attorney-in-fact unless Debtor is in default. Proceeds
of insurance shall be applied, at the option of Secured Party, to repair or
replace the Collateral or to reduce any of the Indebtedness.

5.    REPORTS.

      (a) Debtor shall promptly notify Secured Party of (i) any change in the
name of Debtor, (ii) any change in the state of its incorporation, organization
or registration, (iii) any relocation of its chief executive offices, (iv) any
relocation of any of the Collateral, (v) any of the Collateral being lost,
stolen, missing, destroyed, materially damaged or worn out, or (vi) any lien,
claim or encumbrance other than Permitted Liens attaching to or being made
against any of the Collateral. (b) Debtor will deliver to Secured Party
financial statements as follows. If Debtor is a privately held company, then
Debtor agrees to provide monthly financial statements, certified by Debtor's
president or chief financial officer including a balance sheet, statement of
operations and cash flow statement within 30 days of each month end and its
complete audited annual financial statements, certified by a recognized firm of
certified public accountants, within 120 days of fiscal year end or at such time
as Debtor's Board of Directors receives the audit. If Debtor is a publicly held
company, then Debtor agrees to provide quarterly unaudited statements and annual
audited statements, certified by a recognized firm of certified public
accountants, within 10 days after the statements are provided to the Securities
and Exchange Commission ("SEC"). All such statements are to be prepared using
generally accepted accounting principles ("GAAP") and, if Debtor is a publicly
held company, are to be in compliance with SEC requirements.

6.    FURTHER ASSURANCES.

      (a) Debtor shall, upon request of Secured Party, furnish to Secured Party
such further information, execute and deliver to Secured Party such documents
and instruments (including, without limitation, Uniform Commercial Code
financing statements) and shall do such other acts and things as Secured Party
may at any time reasonably request relating to the perfection or protection of
the security interest created by this Agreement or for the purpose of carrying
out the intent of this Agreement. Without limiting the foregoing, Debtor shall
cooperate and do all acts deemed necessary or advisable by Secured Party to
continue in Secured Party a perfected first security interest in the Collateral,
and shall obtain and furnish to Secured Party any



subordinations, releases, landlord waivers, lessor waivers, mortgagee waivers,
or control agreements, and similar documents as may be from time to time
requested by, and in form and substance satisfactory to, Secured Party.

      (b) Debtor authorizes Secured Party to file a financing statement and
amendments thereto describing the Collateral and containing any other
information required by the applicable Uniform Commercial Code. Debtor
irrevocably grants to Secured Party the power to sign Debtor's name and
generally to act on behalf of Debtor to execute and file applications for title,
transfers of title, financing statements, notices of lien and other documents
pertaining to any or all of the Collateral; this power is coupled with Secured
Party's interest in the Collateral. Debtor shall, if any certificate of title be
required or permitted by law for any of the Collateral, obtain and promptly
deliver to Secured Party such certificate showing the lien of this Agreement
with respect to the Collateral. Debtor ratifies its prior authorization for
Secured Party to file financing statements and amendments thereto describing the
Collateral and containing any other information required by the Uniform
Commercial Code if filed prior to the date hereof.

      (c) Debtor shall indemnify and defend the Secured Party, its successors
and assigns, and their respective directors, officers and employees, from and
against all claims, actions and suits (including, without limitation, related
attorneys' fees) of any kind whatsoever arising, directly or indirectly, in
connection with any of the Collateral.

          (vi) Any of the Collateral is subjected to attachment, execution,
levy, seizure or confiscation in any legal proceeding or otherwise, or if any
legal or administrative proceeding is commenced against Debtor or any of the
Collateral, which in the good faith judgment of Secured Party subjects any of
the Collateral to a material risk of attachment, execution, levy, seizure or
confiscation and no bond is posted or protective order obtained to negate such
risk;



          (vii) Debtor breaches or is in default under any other agreement
between Debtor and Secured Party;

condition as determined solely by Secured Party;

          (xiv) Any Guarantor revokes or attempts to revoke its guaranty of any

than 50% of its interest in the company to another corporation or business or
all or substantially all of its assets without Secured Party's prior written
consent.

      (b) If Debtor is in default, the Secured Party, at its option, may declare
any or all of the Indebtedness to be immediately due and payable, without demand
or notice to Debtor or any Guarantor. The accelerated obligations and
liabilities shall bear interest (both before and after any judgment) until paid
in full at the lower of eighteen percent (18%) per annum or the maximum rate not
prohibited by applicable law.

      (c) After default, Secured Party shall have all of the rights and remedies
of a Secured Party under the Uniform Commercial Code, and under any other

make it available to Secured Party at a place to be designated by Secured Party
which is reasonably convenient to both parties. Secured Party may also render
any or all of the Collateral unusable at the Debtor's premises and may dispose
of such Collateral on such premises without liability for rent or costs. Any
notice that Secured Party is required to give to Debtor under the Uniform
Commercial Code of the time and place of any public sale or the time after which
any private sale or other intended disposition of the Collateral is to be made
shall be deemed to constitute reasonable notice if such notice is given to the
last known address of Debtor at least five (5) days prior to such action.

first, to all costs of repossession, storage, and disposition including without

Debtor shall remain fully liable for any deficiency.

      (e) Debtor agrees to pay all reasonable attorneys' fees and other costs
incurred by Secured Party in connection with the enforcement, assertion, defense
or preservation of Secured Party's rights and remedies under this Agreement, or
if prohibited by law, such lesser sum as may be permitted. Debtor further agrees
that such fees and costs shall constitute Indebtedness.

      (f) Secured Party's rights and remedies under this Agreement or otherwise
arising are cumulative and may be exercised singularly or concurrently. Neither
the failure nor any delay on the part of the Secured Party to exercise any
right, power or privilege under this Agreement shall operate as a waiver, nor
shall any single or partial exercise of any right, power or privilege preclude
any other or further exercise of that or any other right, power or privilege.
SECURED PARTY SHALL NOT BE DEEMED TO HAVE WAIVED ANY OF ITS RIGHTS UNDER THIS
AGREEMENT OR UNDER ANY OTHER AGREEMENT, INSTRUMENT OR PAPER SIGNED BY DEBTOR
UNLESS SUCH WAIVER IS EXPRESSED IN WRITING AND SIGNED BY SECURED PARTY. A waiver
on any one occasion shall not be construed as a bar to or waiver of any right or
remedy on any future occasion.

      (g) DEBTOR AND SECURED PARTY UNCONDITIONALLY WAIVE THEIR RIGHTS TO A JURY
TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS
AGREEMENT, ANY OF THE OTHER DEBT DOCUMENTS, ANY OF THE INDEBTEDNESS SECURED
HEREBY, ANY DEALINGS BETWEEN DEBTOR AND SECURED PARTY RELATING TO THE SUBJECT
MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP

WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE

8.    MISCELLANEOUS.

      (a) This Agreement, any Note and/or any of the other Debt Documents may be
assigned, in whole or in part, by Secured Party without notice to Debtor, and
Debtor agrees not to assert against any such assignee, or assignee's assigns,
any defense, set-off, recoupment claim or counterclaim which Debtor has or may
at any time have against Secured Party for any reason whatsoever. Debtor agrees
that if Debtor receives written notice of an assignment from Secured Party,
Debtor will pay all amounts payable under any assigned Debt Documents to such
assignee or as instructed by Secured Party. Debtor also agrees to confirm in
writing receipt of the notice of assignment as may be reasonably requested by
Secured Party or assignee.

      (b) All notices to be given in connection with this Agreement shall be in
writing, shall be addressed to the parties at their respective addresses set
forth in this Agreement (unless and until a different address may be specified
in a written notice to the other party), and shall be deemed given (i) on the
date of receipt if delivered in hand or by facsimile transmission, (ii) on the
next business day after being sent by express mail, and (iii) on the fourth
business day after being sent by regular, registered or certified mail. As used

SCHEDULES SHALL NOT BE CHANGED OR TERMINATED ORALLY OR BY COURSE OF CONDUCT, BUT

construction or interpretation of this Agreement.

      (f) This Agreement shall continue in full force and effect until all of
the Indebtedness has been indefeasibly paid in full to Secured Party or its
assignee. The surrender, upon payment or otherwise, of any Note or any of the
other documents evidencing any of the Indebtedness shall not affect the right of
Secured Party to retain the Collateral for such other Indebtedness as may then
exist or as it may be reasonably contemplated will exist in the future. This
Agreement shall automatically be reinstated if Secured Party is ever required to
return or restore the payment of all or any portion of the Indebtedness (all as
though such payment had never been made).

Party to use Debtor's name, logo and/or trademark, in any promotional materials
of Secured Party.

bound hereby, have duly executed this Agreement in one or more counterparts,
each of which shall be deemed to be an original, as of the day and year first
aforesaid.
