the reasons such System does not comply with the relevant Statement of Work and
the Specifications applicable to such System.

     (f)   REJECTION. If Buyer notifies Seller during the applicable Inspection
Period that any System delivered hereunder is rejected for failure to comply
with the relevant Statement of Work and the Specifications applicable to such
System, and if Seller confirms such non-compliance, then, Seller shall, at no
additional charge and as soon as reasonably practicable, use commercially
reasonable efforts to cause the rejected System to comply to the relevant
Statement of Work and the Specifications applicable to such System or replace
the rejected System with a conforming System.

     (g)   DEEMED ACCEPTANCE. Except in the event of any investigation,
corrective action or retesting of a System under this Section 5, should Buyer
fail to provide Seller with written notice of its acceptance or rejection within
the applicable Inspection Period, then the System shall be deemed to have been
accepted by Buyer on the fifteenth (15th) business day after the latter of (i)
receipt of such System at the applicable Delivery Location, or (ii) the
completion of Seller's Integration Services, if applicable.

6.   TERM

     The term of this Contract (the "TERM") shall commence on the Effective Date
and terminate on December 31, 2003, unless terminated earlier in accordance with
Section 9 below. The parties may extend the Term for additional two-year periods
by mutual written agreement. Such additional two-year periods, shall also be
considered the "Term," as applicable.

8.   WARRANTIES AND REMEDIES

     (a)   LIMITED WARRANTY. Seller warrants that each System sold to Buyer
pursuant to this Contract will be free from any material defects in design,
materials and workmanship ("LIMITED WARRANTY") for the first to occur of a
period of twelve (12) months from the date of final acceptance of the System by
Buyer in accordance with Section 5(e), or fifteen (15) months from the date of
installation of the System (the "WARRANTY PERIOD"). If, during the Warranty
Period, Buyer notifies Seller in writing that the Limited Warranty is breached
with respect to a System, and demonstrates material defect(s) in design,
materials and workmanship, and none of the exceptions specified below exist,
then Seller shall, at its expense, repair or replace defective equipment or
components and use commercially reasonable efforts to correct any other material
defect(s) in designs, materials and workmanship identified in writing by Buyer.
This Limited Warranty shall not apply: (i) if the System has been modified,
changed or altered by anyone other than Seller; (ii) if the System is improperly
installed and Seller did not provide the installation services, (iii) if the
System is being improperly operated and/or used in any way other than as
contemplated by its Specifications or the applicable Statement of Work; or
(iv) if the damage or defect is caused by fire, flood, wind, lightning or
similar occurrences. If any of Buyer's warranty claims fall within any of the
above exceptions, then the Limited Warranty shall become immediately null and
void and shall be of no further force or effect with respect to such System and
Buyer shall pay Seller's costs of investigating and identifying the problem, and
Seller's expenses to repair or correct the problem, based on Seller's
then-current charges.

     (b)   LIMITED PERFORMANCE WARRANTY. Seller further warrants that as of the
latter of (i) the delivery of a System to Buyer at the applicable Delivery
Location, or (ii) the completion of Seller's Integration Services, if
applicable, and for the duration of the Inspection Period applicable to such
System, each such System supplied hereunder shall materially comply the relevant
Statement of Work and the Specifications applicable to such System and will
perform and operate substantially in accordance with the Specifications
applicable to such System and the performance criteria set forth in Buyer's
applicable Statement of Work. If, during the Inspection Period, any System does
not comply with the relevant Statement of Work and the Specifications applicable
to such System or does not perform or operate substantially in accordance with
the Specifications applicable to such System and performance criteria in the
relevant Statement of Work, then Seller shall, at its expense, repair or replace
nonconforming components of the System and shall use commercially reasonable
efforts to correct any other defects in the System.

     (c)   COMPLIANCE WITH LAW. Seller further warrants, provided installation
of a System is performed by Seller, that as of the completion of Seller's
Integration Services with respect to such System, such System will substantially
conform in all material respects to the then-in-effect requirements of any
federal, state or local governmental rule, regulation or standard governing the
operation or use of such System on such date.

     (d)   SERVICES WARRANTY. Seller warrants that the Services will be
performed only by personnel who are trained and qualified to perform such
Services and that all Services shall be performed professionally and in
compliance with the specifications and performance standards set forth in the
applicable Statement of Work.

                                       11

     (e)   THE ABOVE WARRANTIES ARE IN LIEU OF ALL OTHER EXPRESS OR IMPLIED
WARRANTIES, EXPRESS OR IMPLIED, AND SELLER SPECIFICALLY DISCLAIMS ALL SUCH OTHER
EXPRESS OR IMPLIED WARRANTIES AND/OR AGREEMENTS INCLUDING BUT NOT LIMITED TO THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
EXCEPT FOR DAMAGES ARISING FROM DEATH OR BODILY INJURY TO THE EXTENT CAUSED
DIRECTLY BY THE ACTS OR OMISSIONS OF SELLER, SELLER SHALL NOT BE LIABLE TO BUYER
OR ITS AFFILIATES FOR ANY DAMAGES IN CONNECTION WITH THE SALE OF SYSTEMS OR THE
PERFORMANCE OF SERVICES UNDER THIS CONTRACT, WHETHER ARISING IN CONTRACT, TORT,
STRICT LIABILITY OR OTHERWISE UNDER ANY ONE STATEMENT WORK IN EXCESS OF THE
PURCHASE PRICE FOR THE SYSTEMS AND SERVICES PROVIDED AND PAID TO SELLER BY BUYER
AND RETAINED BY SELLER UNDER THE SPECIFIC STATEMENT OF WORK GIVING RISE TO
BUYER'S CLAIM.

     (f)   TO THE MAXIMUM EXTENT PERMITTED UNDER APPLICABLE LAW, SELLER'S ENTIRE
LIABILITY TO BUYER FOR SERVICES REGARDLESS OF THE FORM OF ACTION SHALL IN NO
EVENT EXCEED TOTAL PURCHASE PRICE PAID TO SELLER BY BUYER AND RETAINED BY SELLER
FOR THE SPECIFIC SERVICE GIVING RISE TO BUYER'S CLAIM.

     (g)   NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, NO PARTY SHALL BE
LIABLE FOR ANY INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY
DAMAGES, WHETHER FORESEEABLE OR NOT, THAT ARE IN ANY WAY RELATED TO THIS
CONTRACT, THE BREACH THEREOF, THE USE OR INABILITY TO USE THE SYSTEMS, THE
RESULTS GENERATED FROM THE USE OF THE SYSTEMS, THE QUALITY OF THE SYSTEMS, ANY
DEFECT IN THE SYSTEMS, FAILURE OF THE SYSTEMS TO PERFORM AS REPRESENTED OR
EXPECTED, THE SERVICES, THE USE OR INABILITY TO USE RESULTS OF THE SERVICES, ANY
TRANSACTIONS RESULTING FROM THIS CONTRACT, LOSS OF GOODWILL OR PROFITS, LOST
BUSINESS HOWEVER CHARACTERIZED AND/OR FROM ANY OTHER CAUSE WHATSOEVER.

     (h)   THE PARTIES FURTHER AGREE THAT EACH AND EVERY PROVISION OF THIS
CONTRACT THAT PROVIDES FOR A LIMITATION OF LIABILITY, DISCLAIMER OF WARRANTIES
OR EXCLUSION OF DAMAGES IS EXPRESSLY INTENDED TO BE SEVERABLE AND INDEPENDENT OF
ANY OTHER PROVISION SINCE THOSE PROVISIONS REPRESENT SEPARATE ELEMENTS OF RISK
ALLOCATION BETWEEN THE PARTIES AND SHALL BE SEPARATELY ENFORCED.

9.   TERMINATION

     (a)   INSOLVENCY. Either party shall be entitled to terminate this Contract
and any outstanding Statement of Work, and the parties' duties and obligations
hereunder and thereunder, on thirty (30) days prior written notice to the other
party in the event the other party becomes insolvent or seeks protection,
voluntarily or involuntarily, under applicable bankruptcy laws.

                                       12
<Page>

     (b)   PAYMENT DEFAULT. This Contract, and the parties' duties and
obligations hereunder, may be terminated by Seller upon Buyer's failure to make
payment under any undisputed portion of any invoice on the due date for such
invoice and Buyer's failure to cure such delinquency within ten (10) days
following receipt of written notice thereof from Seller to Buyer. Seller may not
withhold performance or term this Contract if Buyer disputes any invoice or
portion of any invoice in good faith and fails to pay such invoice while the
dispute is pending. Buyer may withhold payment in whole or part of any amount
due or claimed by Seller to such extent as may be necessary to protect Buyer or
its Affiliates from loss on account of defective Systems or Services, third
party claims arising from Seller's performance under this Contract, failure of
Seller to make payments promptly to employees, suppliers and contractors,
exceptions through audits or liabilities of Seller to Buyer under this Contract.

     (c)   TERMINATION FOR CAUSE. Either party may terminate this Contract at
any time during Term, upon forty-five (45) days prior written notice to the
other party, if the other party materially breaches any term or condition of
this Contract (other than a payment default under Section 9(b)) and fails to
cure such breach within the forty-five (45) day cure period. As used in this
Contract, a "material breach" shall mean a material misstatement or omission in
any representation or warranty of a party, or a breach or default in the
performance of any agreement, covenant or obligations of a party hereto which,
in any such case, deprives the non-breaching party of a material right or
benefits in any material respect.

     (d)   TERMINATION FOR PATENT CAUSE. If Seller's U.S. Letters Patent Number
5,396,074 is determined to be invalid or unenforceable by a final non-appealable
judgment of a court of competent jurisdiction, then Buyer shall have the right,
but not the obligation, to terminate this Contract upon thirty (30) days'
written notice to Seller.

     (e)   EFFECT OF TERMINATION. In the event of termination, both parties
shall be liable for all obligations that accrued prior to termination, including
completion of deliveries under any open Statement of Work unless the
non-breaching party elects not to have the open Statement of Work completed, and
for all obligations that survives the termination or expiration of this
Contract.

10.  COMPLIANCE WITH LAWS; APPROVALS

     (a)   COMPLIANCE/MANUFACTURING STANDARDS. Seller and Buyer each shall be
responsible for complying with all applicable legal and regulatory requirements
of the United States and any other national, supranational (e.g., European
Union), state or local regulatory agency, department, bureau, commission,
council or other governmental entity regarding the manufacture and supply of
Systems and performance of Services under this Contract. All Systems supplied in
connection with the Titan Scan Business shall be manufactured in accordance with
good manufacturing practice regulations promulgated by the Food and Drug
Administration from time to time to the extent such regulations apply to the
Systems as used in the Titan Scan Business.

     (b)   GOVERNMENTAL INSPECTIONS. Seller shall give Buyer or its affected
Affiliate prompt notice of any impending inspections by a governmental agency of
the facility used for or processes involved in the manufacture of the Systems,
and shall provide Buyer and its Affiliate

                                       13
<Page>

an opportunity to observe such inspection. Seller shall provide Buyer with
copies of inspection reports, correspondence and other documents relating to
government inspections. Each party shall promptly notify the other of new
instructions, regulations or specifications of which it becomes aware which are
relevant to the manufacture of the Systems under this Contract and which are
required by the Food and Drug Administration or other U.S. federal agency,
equivalent foreign regulatory agencies, or other applicable laws or governmental
regulations and shall confer with each other with respect to the best means to
comply with such requirements. Seller shall be responsible for obtaining and
maintaining all necessary plan inspection standards and plant licenses,
registrations or permits to enable the manufacture and sale of the Systems. Each
party will promptly notify the other party of any comments, responses or notices
that a party receives from any governmental authorities which relate to the
regulatory status of the Systems in any applications or fields other than the
irradiation of food, flowers or animal hides.

     (c)   BUYER'S INSPECTIONS. Buyer and its designees and Affiliates shall
have reasonable access to observe and inspect Seller's manufacturing facilities
and procedures, including manufacturing operations, at reasonable intervals and
upon reasonable notice to Seller. Seller shall maintain proper and accurate
records of all manufacturing steps, processes, quality assurance and quality
control procedures and will provide reasonable access to Buyer from time to time
at reasonable intervals and upon Buyer's reasonable request.

11.  CONFIDENTIALITY

     (a)   NON-DISCLOSURE. The parties anticipate that both Buyer and Seller may
learn Confidential and Proprietary Information (as defined below) of the other
as a consequence of the transactions contemplated by this Contract. The parties
therefore agree, on behalf of themselves, their agents, employees, parents,
subsidiaries, officers, directors, and all other persons acting on or for their
behalf, (i) to keep all Confidential and Proprietary Information confidential
and not to disclose such Confidential and Proprietary Information, either
directly or indirectly, to any third party, and (ii) not to use any such
Confidential and Proprietary Information for any purpose other than performance
of this Contract or as otherwise authorized under the License Agreement without
the prior written consent of the non-disclosing party.

     (b)   EXCEPTIONS. The obligations in this Section 11 shall not apply to
any: (i) information that either party knows about the other prior to the
execution of this Contract except any information which is the subject of
unexpired confidentiality obligations; (ii) information that is publicly known,
or becomes publicly known, through no breach by either party; (iii) information
that is rightfully obtained by either party from any third party who has no duty
of confidentiality under this Contract; (iv) information that is independently
developed by or for a receiving party completely apart from the disclosures
hereunder, (v) information that is released pursuant to a binding court order or
government regulation, provided that the receiving party delivers a copy of such
order or action to the other party and reasonably cooperates with the other
party if it elects to contest such disclosure or seek an appropriate remedy such
as a protective order or (vi) is otherwise necessary to disclose in order to
file or prosecute patent applications, prosecute or defend litigation or comply
with applicable law, including regulatory filings, or otherwise establish rights
or enforce obligations under this Contract, but only to the extent that any such
disclosure is reasonably necessary.

                                       14
<Page>

     (c)   PRECAUTIONS. The parties mutually agree to take all reasonably
necessary steps, and to prepare and execute all necessary documents, to protect
and prohibit the disclosure of Proprietary and Confidential Information under
this Section 11 using the higher of a reasonable standard of care or the care
used by such party to protect its own confidential or proprietary information.
Each party will immediately notify the other party of any information that comes
to its attention which might indicate that there has been a loss of
confidentiality with respect to such other party's Confidential and Proprietary
Information.

     (d)   REMEDIES. In the event of a breach or threatened breach by either
party of such party's confidentiality obligations in this Section 11, the
parties acknowledge and agree that it would be difficult to measure the damage
to the non-breaching party from such breach, that injury to such non-breaching
party from such breach would be impossible to calculate and that money damages
would therefore be an inadequate remedy for such breach. Accordingly, the
non-breaching party, in addition to any and all other rights which may be
available, shall have the right of injunctive relief and other appropriate
equitable remedies to restrain any such breach or threatened breach.

     (e)   RETURN OF PROPERTY. Upon request, each party shall immediately return
to the other party the originals and all copies of any Confidential and
Proprietary Infofll1ation of the other party.

12.  OWNERSHIP

     The parties agree that the ownership rights of Seller and Buyer with
respect to the patents, patent applications, copyrights, trade secrets and other
Intellectual Property Rights to the Systems is set forth in the License
Agreement. All modifications, enhancements, improvements to and derivative works
of any Systems or components of any System or any other proprietary information,
data, methods, methodologies, templates, software (including source code and
object code), algorithms, libraries, design flows, processes, databases, tools,
processes, interfaces, documentation, mask works, encoding techniques,
electronic components and other trade secrets and other Intellectual Property
Rights, that are developed, conceived or made by any employee or contractor to
Seller in the course of performing its obligations under any Statement of Work
that do not constitute modifications, enhancement or improvements to the core
System for application in the irradiation or pasteurization of food, flowers or
animal hides (collectively, the "WORKS") shall be, to the maximum extent
possible under applicable law, deemed and meet the definition of "works made for
hire" by Seller for Buyer under U.S. copyright law, and Buyer shall be deemed
the exclusive author and owner of all Works and all Intellectual Property Rights
therein. If any Work does not meet the definition of "work made for hire,"
Seller agrees to irrevocably assign, and hereby does irrevocable assign and
transfer, to Buyer all of its Intellectual Property Rights therein, or if such
assignment is not allowed, hereby grants to Buyer and its Affiliates a
worldwide, exclusive, irrevocable, perpetual royalty-free, fully paid license,
with right to sublicense through multiple tiers of sublicenses, to modify or use
the Works for any and all purposes other than the irradiation or pasteurization
of food, flowers or animal hides. All worldwide rights, title and interest in
any and all trade secrets and know-how discovered or developed by any employee
or consultant of Seller in the course of performing its obligations under a
Statement of Work, excluding trade secrets relating to irradiation or
pasteurization of food, flowers or animal hides, shall be held and owned
exclusively by Buyer

                                       15
<Page>

(the "TRADE SECRETS"), and Seller hereby irrevocably assigns and transfers the
Trade Secrets to Buyer. To the extent that any provision regarding Intellectual
Property Right to the Systems delivered under this Contract is contrary in the
License Agreement, the provision of the License Agreement shall control.

13.  REMEDIES

     The remedies of the parties contained in this Contract are cumulative with
one another and with any other remedies which the parties may have at law, in
equity, under any Contracts of any type or otherwise, and the exercise or
failure to exercise any remedy shall not preclude the exercise of that remedy at
another time or of any other remedy at any time. No waiver of a breach of any
provision of this Contract shall constitute a waiver of any other breach or of
such provision. The invalidity in whole or in part of any condition of this
Contract shall not affect the validity of other conditions.

14.  INSURANCE

     Without limiting any of the other obligations or liabilities of Seller,
Seller shall, at its own expense, secure and maintain in effect during the Term,
and for a period of four years after acceptance of the final System delivered
under a Statement of Work, on an "occurrence" and not a "claims made" basis,
insurance coverages as described herein, in amounts not less than the minimum
limits specified, to protect Buyer from claims or liabilities in any way arising
out of Seller's performance or non-performance under this Contract: (1) workers
compensation insurance and employers liability insurance in accordance with
statutory requirements and limits, (2) commercial general liability insurance,
including products liability coverage, contractual liability coverage and
automobile liability coverage, with limits of not less than Two Million Dollars
($2,000,000) for each occurrence for bodily injury and property damage combined,
and (3) professional indemnity insurance coverage for claims in connection with
its engineering Services, with limits of coverage of at least Two Million
Dollars ($2,000,000). Seller shall name Buyer and its Affiliates and their
directors, officers and employees as additional insureds on the policies of
insurance and endorsements to the policies in a form approved by Buyer and shall
provide to Buyer certificates evidencing this coverage. Seller agrees that the
insurance provided to Buyer under this Contract shall be primary to any
insurance of Buyer for all purposes, such Buyer insurance to be considered as
excess of and not contributing with Buyer's policies. Seller shall be
responsible solely for any deductible or self-insured retention on such
insurance. All such insurance shall contain a severability of interest or cross
liability clause, shall contain a waiver by the insurer of subrogation in favor
of Buyer, and shall provide that the insurance may not be modified, cancelled or
renewed for any reason, except with the insurer giving thirty (30) days' prior
written notice to Buyer. Buyer understands and acknowledges that Seller's cost
for premiums for any insurance required to be maintained under this Section 14
that exceeds the insurance coverage customarily obtained by similar businesses
facing similar risks and that exceeds the insurance requirements of other
customers of Seller that are not affiliated with Buyer shall be deemed Insurance
Costs and shall be allocated to the Cost of Services and Cost of Manufacturing
in accordance with Sections 1(e) and 1(s).

15.  INDEMNITY

     (a)   INDEMNITY. As between Buyer and its Affiliates, on the one hand, and
Seller, on the other hand, Seller shall be solely liable for and Seller shall
indemnify, defend and hold Buyer, and its Affiliates, or its or their directors,
officers, employees, agents, representatives, successors and assigns
(collectively "BUYER INDEMNITEES") harmless from and against any and all claims,
actions, suits, proceedings, losses, liabilities, penalties, damages, costs or
expenses, including attorneys' fees and disbursements, of any kind whatsoever
resulting from (1) injuries to or death of any and all individuals, including
members of general public or any employee, agent or independent contractor of
Buyer or its Affiliates, Seller or any customer of Seller arising out of or
connected in any manner with performance of any Services or any defect in the
System(s) or Seller's failure to warn Buyer, its Affiliates or its customers
about risks relating to the System(s) or use of the System(s), whether or not
the conduct of Seller or any subcontractor was tortious and whether any other
party contributed to the injuries or death, (2) damages to, loss, and/or
destruction of property, including loss of use of any property, arising out of
or connected in any manner with performance of any Services or any defect in the
System(s) or Seller's failure to warn Buyer, its Affiliates or its customers
about risks relating to System(s) or the use of the System(s), whether or not
the conduct of Seller or any subcontractor was tortious and whether any other
party contributed to the property damage, (3) third party claims of any kind,
whether based upon negligence, strict liability or otherwise, arising out of or
connected in any manner to Seller's or any of its contractor's acts or omissions
in breach of this Contract or resulting from failure to comply with this
Contract, or (4) actual or alleged infringement or misappropriation by Seller or
any subcontractor of any intellectual property right in connection with the
Systems or Services or violation of any third party license to use intellectual
property rights in connection with the Systems or Services.

     (b)   DEFENSE OF THIRD PARTY CLAIMS. If any claim is brought against any
Buyer Indemnitees, then Seller shall be entitled to participate in, and, unless
in the opinion of counsel for Buyer a conflict of interest between Buyer and
Seller may exist with respect to such claim or the defense thereof, assume the
defense of, such claim, without any reservation of rights, with counsel
reasonably acceptable to Buyer. If Seller does not assume the defense of Buyer
Indemnitees, without any reservation of rights with respect to the indemnity
obligation, or if a conflict precludes Seller from assuming the defense, then
Seller shall reimburse Buyer on a monthly basis for Buyer Indemnitees defense
through separate counsel of Buyer's choice. Even if Seller assumes the defense
of Buyer Indemnitees without any reservation of rights and with acceptable
counsel, Buyer, at its sole option, may participate in the defense, at its own
expense, with counsel of its own choice without relieving Seller of its
obligations hereunder.

16.  ASSIGNMENT AND DELEGATION

     Neither this Contract nor any right, obligation or duty hereunder of either
party, may be assigned to, or assumed or performed by, any third party, without
the prior written consent of the non-assigning party; provided, however, that a
change in the equity ownership of Seller or Buyer shall be deemed not an
assignment. Any purported assignment or delegation made without compliance with
the requirements of this Section 16 shall be wholly void and ineffective for all
purposes.
