in subsection 3(c).

         (b)  POWERS OF BOARD. The Board shall have the power, subject to, and
within the limitations of, the express provisions of the Plan:

              (i)   To determine from time to time which of the persons
eligible under the Plan shall be granted Options; when and how each Option
shall be granted; the provisions of each Option granted (which need not be

              (ii)  To construe and interpret the Plan and Options granted
under it, and to establish, amend and revoke rules and regulations for its
administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Option Agreement, in a
manner and to the extent it shall deem necessary or expedient to make the Plan
fully effective.

              (iii) To amend the Plan or a Option as provided in Section 11.

              (iv)  Generally, to exercise such powers and to perform such acts

         (c)  DELEGATION TO COMMITTEE.

              (i)   GENERAL. The Board may delegate administration of the Plan
to a Committee or Committees of one (1) or more members of the Board, and the
term "Committee" shall apply to any person or persons to whom such authority

subcommittee any of the administrative powers the Committee is authorized to
exercise (and references in this Plan to the Board shall thereafter be to the
Committee or subcommittee), subject, however, to such resolutions, not
inconsistent with the provisions of the Plan, as may be adopted from time to
time by the Board. The Board may abolish the Committee at any time and revest
in the Board the administration of the Plan.

              (ii)  COMMITTEE COMPOSITION WHEN COMMON STOCK IS PUBLICLY TRADED.
At such time as the Common Stock is publicly traded, in the discretion of the
Board, a Committee may consist solely of two or more Outside Directors, in
accordance with Section 162(m) of the Code, and/or solely of two or more
Non-Employee Directors, in accordance with Rule 16b-3. Within the scope of such
authority, the Board or the Committee may (1) delegate to a committee

4.       SHARES SUBJECT TO THE PLAN.

         (a)  SHARE RESERVE. Subject to the provisions of Section 10 relating
to adjustments upon changes in Common Stock, the Common Stock that may be
issued pursuant to Options shall not exceed in the aggregate Seven Million
Nine Hundred Seventy-Five Thousand One Hundred Thirty-Seven (7,975,137)
shares of Common Stock.

         (b)  REVERSION OF SHARES TO THE SHARE RESERVE. If any Option shall for
any reason expire or otherwise terminate, in whole or in part, without having
been exercised in full, the shares of Common Stock not acquired under such
Option shall revert to and again become available for issuance under the Plan.

         (c)  SOURCE OF SHARES. The shares of Common Stock subject to the Plan
may be unissued shares or reacquired shares, bought on the market or otherwise.

5.       ELIGIBILITY. Subject to the provisions of Section 10 relating to
adjustments upon changes in the shares of Common Stock, no Employee shall be
eligible to be granted Options covering more than Three Million (3,000,000)
shares of Common Stock during any calendar year. This Section 5 shall not apply
prior to the Listing Date and, following the Listing Date, this Section 5 shall
not apply until (i) the earliest of: (1) the first material modification of the
Plan (including any increase in the number of shares of Common Stock reserved
for issuance under the Plan in accordance with Section 4); (2) the issuance of
all of the shares of Common Stock reserved for issuance under the Plan; (3) the
expiration of the Plan; or (4) the first meeting of stockholders at which
Directors are to be elected that occurs after the close of the third calendar
year following the calendar year in which occurred the first registration of an
equity security under Section 12 of the Exchange Act; or (ii) such other date
required by Section 162(m) of the Code and the rules and regulations
promulgated thereunder.

6.       OPTION PROVISIONS.

         Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. All Options shall be designated
Nonstatutory Stock Options at the time of grant, and, if certificates are
issued, a separate certificate or certificates will be issued for shares of
Common Stock purchased on exercise of each type of Option. The provisions of

                                       5
<PAGE>

separate Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

         (a)  TERM. No Option granted prior to the Listing Date shall be
exercisable after the expiration of ten (10) years from February 19, 1998.

         (b)  EXERCISE PRICE OF A NONSTATUTORY STOCK OPTION. The exercise price
of each Nonstatutory Stock Option granted prior to the Listing Date shall be
not less than the Book Value per share on the date the Option is granted. The
exercise price of each Nonstatutory Stock Option granted on or after the
Listing Date shall be not less than eighty-five percent (85%) of the Fair
Market Value of the Common Stock subject to the Option on the date the Option
is granted. Notwithstanding the foregoing, a Nonstatutory Stock Option may be
granted with an exercise price lower than that set forth in the preceding
sentence if such Option is granted pursuant to an assumption or substitution
for another option in a manner satisfying the provisions of Section 424(a) of
the Code.

         (c)  CONSIDERATION. The purchase price of Common Stock acquired
pursuant to an Option shall be paid, to the extent permitted by applicable
statutes and regulations, either (i) in cash at the time the Option is
exercised or (ii) at the discretion of the Board at the time of the grant of
the Option (or subsequently in the case of a Nonstatutory Stock Option) (1) by
delivery to the Company of other Common Stock, (2) according to a deferred
payment or other similar arrangement with the Optionholder or (3) in any other
form of legal consideration that may be acceptable to the Board. Unless
otherwise specifically provided in the Option, the purchase price of Common
Stock acquired pursuant to an Option that is paid by delivery to the Company of
other Common Stock acquired, directly or indirectly from the Company, shall be
paid only by shares of the Common Stock of the Company that have been held for
more than six (6) months (or such longer or shorter period of time required to
avoid a charge to earnings for financial accounting purposes). At any time that
the Company is incorporated in Delaware, payment of the Common Stock's "par
value," as defined in the Delaware General Corporation Law, shall not be made
by deferred payment.

         In the case of any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

         (d)  TRANSFERABILITY OF A NONSTATUTORY STOCK OPTION. A Nonstatutory
Stock Option granted prior to the Listing Date shall not be transferable except
by will or by the laws of descent and distribution and shall be exercisable
during the lifetime of the Optionholder only by the Optionholder. A
Nonstatutory Stock Option granted on or after the Listing Date shall be
transferable to the extent provided in the Option Agreement. If the
Nonstatutory Stock Option does not provide for transferability, then the
Nonstatutory Stock Option shall not be transferable except by will or by the
laws of descent and distribution and shall be exercisable during the lifetime
of the Optionholder only by the Optionholder. Notwithstanding the foregoing,
the Optionholder may, by delivering written notice to the Company, in a form
satisfactory to the

                                       6
<PAGE>

Company, designate a third party who, in the event of the death of the
Optionholder, shall thereafter be entitled to exercise the Option.

         (e)  VESTING GENERALLY. The total number of shares of Common Stock
subject to an Option may, but need not, vest and therefore become exercisable
in periodic installments that may, but need not, be equal. The Option may be
subject to such other terms and conditions on the time or times when it may be
exercised (which may be based on performance or other criteria) as the Board
may deem appropriate. The vesting provisions of individual Options may vary.
The provisions of this subsection 6(f) are subject to any Option provisions
governing the minimum number of shares of Common Stock as to which an Option
may be exercised. Options granted prior to the Listing Date to Officers or
Directors may be made fully exercisable, subject to reasonable conditions such
as continued employment, at any time or during any period established by the
Company.

         (f)  TERMINATION OF CONTINUOUS SERVICE. In the event an Optionholder's
Continuous Service terminates (other than upon the Optionholder's death or
Disability), the Optionholder may exercise his or her Option (to the extent
that the Optionholder was entitled to exercise such Option as of the date of
termination) but only within such period of time ending on the earlier of (i)
the date three (3) months following the termination of the Optionholder's
Continuous Service (or such longer or shorter period specified in the Option
Agreement, which period shall not be less than thirty (30) days for Options
granted prior to the Listing Date unless such termination is for cause), or
(ii) the expiration of the term of the Option as set forth in the Option
Agreement. If, after termination, the Optionholder does not exercise his or her
Option within the time specified in the Option Agreement, the Option shall
terminate.

         An Optionholder's Option Agreement may also provide that if the
exercise of the Option following the termination of the Optionholder's
Continuous Service (other than upon the Optionholder's death or Disability)
would be prohibited at any time solely because the issuance of shares of Common
Stock would violate the registration requirements under the Securities Act,
then the Option shall terminate on the earlier of (i) the expiration of the
term of the Option set forth in subsection 6(a) or (ii) the expiration of a
period of three (3) months after the termination of the Optionholder's
Continuous Service during which the exercise of the Option would not be in
violation of such registration requirements.

         (g)  DISABILITY OF OPTIONHOLDER. In the event that an Optionholder's
Continuous Service terminates as a result of the Optionholder's Disability, the
Optionholder may exercise his or her Option (to the extent that the
Optionholder was entitled to exercise such Option as of the date of
termination), but only within such period of time ending on the earlier of (i)
the date twelve (12) months following such termination (or such longer or
shorter period specified in the Option Agreement, which period shall not be
less than six (6) months for Options granted prior to the Listing Date) or (ii)
the expiration of the term of the Option as set forth in the Option Agreement.
If, after termination, the Optionholder does not exercise his or her Option
within the time specified herein, the Option shall terminate.

         (h)  DEATH OF OPTIONHOLDER. In the event (i) an Optionholder's
Continuous Service terminates as a result of the Optionholder's death or (ii)
the Optionholder dies within the period

                                       7
<PAGE>

(if any) specified in the Option Agreement after the termination of the
Optionholder's Continuous Service for a reason other than death, then the
Option may be exercised (to the extent the Optionholder was entitled to
exercise such Option as of the date of death) by the Optionholder's estate, by
a person who acquired the right to exercise the Option by bequest or
inheritance or by a person designated to exercise the option upon the
Optionholder's death pursuant to subsection 6(e), but only within the period
ending on the earlier of (1) the date eighteen (18) months following the date
of death (or such longer or shorter period specified in the Option Agreement,
which period shall not be less than six (6) months for Options granted prior to
the Listing Date) or (2) the expiration of the term of such Option as set forth
in the Option Agreement. If, after death, the Option is not exercised within
the time specified herein, the Option shall terminate.

         (i)  EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionholder may elect at any time before the Optionholder's
Continuous Service terminates to exercise the Option as to any part or all of
the shares of Common Stock subject to the Option prior to the full vesting of
the Option. Any unvested shares of Common Stock so purchased may be subject to
a repurchase option in favor of the Company or to any other restriction the
Board determines to be appropriate. The Company will not exercise its
repurchase option until at least six (6) months (or such longer or shorter
period of time required to avoid a charge to earnings for financial accounting
purposes) have elapsed following exercise of the Option unless the Board
otherwise specifically provides in the Option.

         (j)  RIGHT OF REPURCHASE. The Option may, but need not, include a
provision whereby the Company may elect, prior to the Listing Date, to
repurchase all or any part of the vested shares of Common Stock acquired by the
Optionholder pursuant to the exercise of the Option at a price per share equal
to the Book Value per share on the date of repurchase.

         (k)  RIGHT OF FIRST REFUSAL. The Option may, but need not, include a
provision whereby the Company may elect, prior to the Listing Date, to exercise
a right of first refusal following receipt of notice from the Optionholder of
the intent to transfer all or any part of the shares of Common Stock received
upon the exercise of the Option. Except as expressly provided in this
subsection 6(m), such right of first refusal shall otherwise comply with any
applicable provisions of the Bylaws of the Company.

7.       COVENANTS OF THE COMPANY.

         (a)  AVAILABILITY OF SHARES. During the terms of the Options, the
Company shall keep available at all times the number of shares of Common Stock
required to satisfy such Options.

         (b)  SECURITIES LAW COMPLIANCE. The Company shall seek to obtain from
each regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to grant Options and to issue and sell shares of
Common Stock upon exercise of the Options; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
the Plan, any Option or any Common Stock issued or issuable pursuant to any
such Option. If, after reasonable efforts, the Company is unable to obtain from
any such regulatory commission or agency the authority which counsel for the
Company deems necessary

                                       8
<PAGE>

for the lawful issuance and sale of Common Stock under the Plan, the Company
shall be relieved from any liability for failure to issue and sell Common Stock
upon exercise of such Options unless and until such authority is obtained.

8.       USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of Common Stock pursuant to Options shall
constitute general funds of the Company.

9.       MISCELLANEOUS.

         (a)  ACCELERATION OF EXERCISABILITY AND VESTING. The Board shall have
the power to accelerate the time at which a Option may first be exercised or
the time during which a Option or any part thereof will vest in accordance with
the Plan, notwithstanding the provisions in the Option stating the time at
which it may first be exercised or the time during which it will vest.

         (b)  STOCKHOLDER RIGHTS. No Participant shall be deemed to be the
holder of, or to have any of the rights of a holder with respect to, any shares
of Common Stock subject to such Option unless and until such Participant has
satisfied all requirements for exercise of the Option pursuant to its terms.

         (c)  NO EMPLOYMENT OR OTHER SERVICE RIGHTS. Nothing in the Plan or any
instrument executed or Option granted pursuant thereto shall confer upon any
Participant any right to continue to serve the Company or an Affiliate in the
capacity in effect at the time the Option was granted or shall affect the right
of the Company or an Affiliate to terminate (i) the employment of an Employee
with or without notice and with or without cause, or (ii) the service of a
Director pursuant to the Bylaws of the Company or an Affiliate, and any
applicable provisions of the corporate law of the state in which the Company or
the Affiliate is incorporated, as the case may be.

         (d)  INVESTMENT ASSURANCES. The Company may require a Participant, as
a condition of exercising or acquiring Common Stock under any Option, (i) to
give written assurances satisfactory to the Company as to the Participant's
knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Option; and (ii) to give
written assurances satisfactory to the Company stating that the Participant is
acquiring Common Stock subject to the Option for the Participant's own account
and not with any present intention of selling or otherwise distributing the
Common Stock. The foregoing requirements, and any assurances given pursuant to
such requirements, shall be inoperative if (1) the issuance of the shares of
Common Stock upon the exercise or acquisition of Common Stock under the Option
has been registered under a then currently effective registration statement
under the Securities Act or (2) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such

                                       9
<PAGE>

counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the
transfer of the Common Stock.

         (e)  WITHHOLDING OBLIGATIONS. To the extent provided by the terms of a
Option Agreement, the Participant may satisfy any federal, state or local tax
withholding obligation relating to the exercise or acquisition of Common Stock
under a Option by any of the following means (in addition to the Company's
right to withhold from any compensation paid to the Participant by the Company)
or by a combination of such means: (i) tendering a cash payment; (ii)
authorizing the Company to withhold shares of Common Stock from the shares of
Common Stock otherwise issuable to the Participant as a result of the exercise
or acquisition of Common Stock under the Option, provided, however, that no
shares of Common Stock are withheld with a value exceeding the minimum amount
of tax required to be withheld by law; or (iii) delivering to the Company owned
and unencumbered shares of Common Stock.

10.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a)  CAPITALIZATION ADJUSTMENTS. If any change is made in the Common
Stock subject to the Plan, or subject to any Option, without the receipt of
consideration by the Company (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange
of shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan will be appropriately
adjusted in the class(es) and maximum number of securities subject to the Plan
pursuant to subsection 4(a) and the maximum number of securities subject to
award to any person pursuant to Section 5, and the outstanding Options will be
appropriately adjusted in the class(es) and number of securities and price per
share of Common Stock subject to such outstanding Options. The Board shall make
such adjustments, and its determination shall be final, binding and conclusive.

treated as a transaction "without receipt of consideration" by the Company.)

         (b)  CHANGE IN CONTROL--DISSOLUTION OR LIQUIDATION. In the event of a
dissolution or liquidation of the Company, then all outstanding Options shall
terminate immediately prior to such event.

         (c)  CHANGE IN CONTROL--ASSET SALE, MERGER, CONSOLIDATION OR REVERSE
MERGER. In the event of (i) a sale, lease or other disposition of all or
substantially all of the assets of the Company, (ii) a merger or consolidation

Stock outstanding immediately preceding the merger are converted by virtue of
the merger into other property, whether in the form of securities, cash or
otherwise, then any surviving corporation or acquiring corporation shall assume
any Options outstanding under the Plan or shall substitute similar Options
(including an award to acquire the same consideration paid to the stockholders
in the transaction described in this subsection 10(c) for those outstanding
under the Plan). In the event any surviving corporation or acquiring
corporation refuses to assume such Options or to substitute similar Options for
those outstanding under the Plan, then with respect to Options held by
Participants whose Continuous Service has not terminated, the

                                       10

other Options outstanding under the Plan, such Options shall terminate if not
exercised (if applicable) prior to such event.

11.      AMENDMENT OF THE PLAN AND OPTIONS.

         (a)  AMENDMENT OF PLAN. The Board at any time, and from time to time,
may amend the Plan. However, except as provided in Section 10 relating to
adjustments upon changes in Common Stock, no amendment shall be effective

approval is necessary to satisfy the requirements of Section 422 of the Code,
Rule 16b-3 or any Nasdaq or securities exchange listing requirements.

         (b)  STOCKHOLDER APPROVAL. The Board may, in its sole discretion,

exclusion of performance-based compensation from the limit on corporate
deductibility of compensation paid to certain executive officers.

         (c)  CONTEMPLATED AMENDMENTS. It is expressly contemplated that the

thereunder relating to Incentive Stock Options and/or to bring the Plan and/or
Incentive Stock Options granted under it into compliance therewith.

         (d)  NO IMPAIRMENT OF RIGHTS. Rights under any Option granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless
(i) the Company requests the consent of the Participant and (ii) the
Participant consents in writing.

         (e)  AMENDMENT OF OPTIONS. The Board at any time, and from time to
time, may amend the terms of any one or more Options; provided, however, that
the rights under any Option shall not be impaired by any such amendment unless

Participant consents in writing.

shall be consistent with the Company's then current strategic plan and shall
include a capital and operating budget for the relevant fiscal year and specify
any dividend or other quotaholder distributions, and shall be implemented
following unanimous ratification and approval by the Board of Directors. Absent

          (i)  Titan SureBeam Brazil may elect, in its sole discretion, to
               obtain financing for the equipment, systems and services sold
               to the Company. If Titan SureBeam Brazil makes this election,
               and such financing is obtained, the payment of 75% of profit or
               fixed payment, as described in 6.1(b)(ii) below, will not be in

         (ii)  If Titan SureBeam Brazil elects, in its sole discretion, not to
               obtain financing for the equipment, systems and services sold

               entitled to receive 19.9% and Tech Ion the other 80.1% of the

               Titan Surebeam Brazil or Surebeam Holding Company Ltda. shall
               enter into a Technology License Agreement whereby one or the
               other will receive a royalty payment equal to 19.9% of the net
               profits.

business in general. Additionally, Tech Ion agrees to be a significant and
primary customer of the Company and agrees to enter into long term "take or pay"
type service contracts with the Company for the irradiation of food and food
products at market rates or competitive pricing.

6.3   COBALT SYSTEMS. Should the Company need to specifically purchase cobalt
systems and services for a specific application, the Parties agree that it
will purchase or otherwise acquire such cobalt systems and services from Tech
Ion. The prices for such cobalt systems or services will be at a price no
greater than the market value of such cobalt systems and services. The market
value will be reviewed annually by the Board of Directors and will be
compared to, among other things, written proposals containing substantially
similar scope of work under substantially similar terms and conditions.

6.4   RIGHT OF FIRST REFUSAL. Should Titan SureBeam Brazil, Tech Ion and the
Company jointly determine that electron beam and/or x-ray systems, equipment
and services are not the preferred source of irradiation for a particular
application, then Titan SureBeam Brazil and the Company shall have a right of
first refusal to collectively provide the non-

electron beam or electron beam system, equipment or services, which can come
either from Brazil or from abroad. If Titan SureBeam Brazil and the Company
elect not to provide the non-electron/x-ray beam system, equipment or
services, then Tech Ion may obtain such non-electron/x-ray beam system,
equipment or services from a third party source or provide the system,
equipment, or services itself.

6.5  TRADEMARKS. The Parties agree that trademarks, service marks, trade names,
logos, insignia and symbols (hereinafter collectively referred to as "INSIGNIA")
of any Party or any of its Affiliates will not be used by any other Party or the
Company in any way or manner without the prior written approval of the Party
owning such Insignia. Such approval shall be limited to the particular instance
giving rise to the need for such approval and shall not be construed as an
ongoing license or approval to use such Insignia in any other instances unless
otherwise agreed to by both parties in writing. The Parties will submit to the
owner of such Insignia all sales promotions, press releases and other publicity
matters furnished by them in connection with this Agreement in which any of the
Insignia is mentioned or language from which the connection of such Insignia may
be inferred or implied.

The Company will enter into Trademark License Agreements with both Surebeam
Corporation and Tech Ion pursuant to which the Company shall use the Surebeam
Corporation and Tech Ion Insignias, respectively, either alone or in co-branding
the Company's services, and in marketing and promoting the sale of such
services, subject to marketing considerations.

6.6  TECHNOLOGY DEVELOPMENT/PATENTS. If any technology development is
required by the Company during the term of this Agreement, Titan SureBeam
Brazil will be given a right of first refusal to provide such technology
development on reasonable market terms. If for any reason Titan SureBeam
elects not to provide such technology development to the Company, then Tech
Ion shall have the right to provide such technology development on reasonable
market terms. Titan SureBeam Brazil and Tech Ion, as the case may be, will be
the owner of any and all rights to the technology developed by them,
including the rights to any patents that may result, and will grant to the
Company a non-exclusive, royalty-free license to use such developed
technology so long as Titan SureBeam Brazil and Tech Ion have at least 19.9%
and 50% ownership interest in the Company, respectively. Any such development
shall be pursuant to a separate development agreement that will incorporate
these principal terms. If neither Titan SureBeam Brazil nor Tech Ion elect
not to provide such technology development, the Company may have such work
performed by a third party. The rights to the technology developed by such
third party will be owned by the Company, including any patents that may
result, and the Company will grant to Titan SureBeam Brazil and to Tech Ion a
non-exclusive, royalty-free license to use such developed technology so long
as Titan Surebeam Brazil and Tech-Ion have at least 19.9% and 50% ownership
interest in the Company, respectively. Any such development shall be pursuant
to a separate development agreement that will incorporate these principal
terms.

Any technology developed during the term of this Agreement, as described above,
shall

                                       18

<PAGE>

be applied, licensed, and/or exploited in Latin America exclusively through the
Company during the term of this Agreement. If such technology is applied,
licensed and/or exploited outside of Latin America, then the Company will be
entitled to receive [...***...] of the resulting net, after tax, profits with
respect thereto during the term of the Agreement.

6.7   COMPLIANCE WITH LAWS. In performing the transactions contemplated in this
Agreement, each Party shall comply with, and shall cause the Company to comply
with, all applicable laws, rules and regulations of Brazil, and the U.S. Foreign
Corrupt Practices Act, as applicable, and each Party shall hold the other
harmless from its failure to do so.

Neither Party nor the Company shall offer, give, promise or pay or cause to be
offered, given, promised or be paid directly or indirectly any money or thing of
value to any political party or official thereof, any candidate for political
office, or any officer, employee or agent of any government or instrumentality
of any government for the purposes of

          (i)  influencing any act or decision of such party, official thereof,
               candidate, officer, employee or agent in his or its official
               capacity, including a decision to fail to perform his or its
               official functions with respect to any transaction contemplated
               herein; or,

         (ii)  inducing any such party official thereof, candidate, officer,
               employee or agent to use his or its influence with a government
               or instrumentality thereof to affect or influence any act or
               decision of such government or instrumentality in order to assist
               either Party or the Company in obtaining or retaining business
               from or with, or directing business to, any person, firm or
               corporation.

Neither Party nor the Company shall offer, give promise to pay, or cause to be
offered, given, promised or be paid any money or thing of value directly or
indirectly to any directors, officers, officials, employees or shareholders of
any nongovernmental customer or prospective customer or to such person's family,
or that are otherwise illegal under applicable law.

6.8   NON-COMPETE.

     (a)  Based on the intention of the Parties that the Company is to be the
          exclusive means by which the Parties or any of their Affiliates its
          Affiliates either obtain and/or provide, as applicable in accordance
          with the activities of each Party, electron beam and x-ray systems,
          equipment and services in Brazil, the Parties agree that, as long as
          each of them is a Party to this Agreement, neither such Party, nor any
          of its Affiliates, shall, without the prior written consent of the
          Company, either individually or in association with others, establish,
          facilitate the business of,

                                       19

          operate, control, or have an ownership interest in or an employment
          relationship with, directly or indirectly, any entity that carries on
          the business of providing food and food product irradiation and
          pasteurization services and industrial irradiation equipment using
          electron beam and x-ray systems or technology to various food
          companies in Brazil, or any other business activity undertaken by the
          Company.

     (b)  the Parties shall promptly notify the Company in writing of any offer
          they receive to enter into an arrangement that could result in a
          violation of Section 6.1(a) and shall promptly remit to the Company
          any profits, compensation, or other remuneration that such Party
          receives as result of a violation of Section 6.1(a).

     (c)  Nothing in this Section 6.1 shall prevent the Parties from owning
          [...***...] of the securities of any publicly traded company.

     (d)  As a condition to employment or other engagement by the Company, the
          Board of Directors may require that any officer or other employee of
          the Company, or any consultant or other independent contractor engaged
          by the Company, enter into a covenant similar to the provisions of
          Section 6.1(a) and (b), both on his or her own behalf, on behalf of
          his or her extended family, or on behalf of his or her employer, as
          the case may be.

7.   CONFIDENTIALITY. For purposes of this Section 7, the term "PARTY" shall be
     interpreted to mean Surebeam Corporation, Tech Ion, Titan Surebeam Brazil
     and the Company.

7.1  Each Party undertakes with the others to keep and procure that its
Affiliates, directors and employees keep in strict confidence all information,
knowledge, experience, data, drawings, designs and other material of a
confidential nature ("INFORMATION") communicated to it by or acquired from the
other or as a result of this Agreement. Included in the definition of
Information is information relating to the business of the Company as well as
information relating to the business of Surebeam Corporation (whether or not
such information relates to the territory in which the Company or Surebeam
Corporation or Titan Surebeam Brazil does business). No Party shall disclose any
such Information to any person whatsoever other than its directors or employees
directly concerned in the performance of this Agreement and the affairs of the
Company. Information made available to a Party as a result of the performance of
this Agreement shall not be used in competition with the other Party.

7.2  The provisions of this Section shall not apply to information which the
party concerned can prove was in its possession at the date of receipt or which
becomes public knowledge (except by reason or default of such Party) or which
such Party obtains from some other person with good legal title thereto, or is
independently developed by such Party.

7.3  Notwithstanding the provisions of this Section, each Party shall be at
liberty to disclose information where, and to the extent that, such disclosure
is properly made pursuant to

                                       20

                     * Confidential Treatment Requested

<PAGE>

and in accordance with a relevant statutory obligation or as otherwise may be
required by the Company in its business and regulatory activities with
government agencies, vendors or bankers; PROVIDED however that the disclosing
Party shall take reasonable steps to obtain, if possible, a written
confidentiality undertaking from the person to whom it wishes to disclose such
information, that is consistent with the terms of this Section and that the
Party from whom the disclosing party obtained the relevant information is given
prior written notice of such disclosure.

7.4  The provisions of this Section 7 shall remain in force for a period of
three years after termination of this Agreement for any reason.

8.   SALE AND ASSIGNMENT OF OWNERSHIP.

8.1  TRANSFER RESTRICTION. Neither Tech Ion nor Titan Surebeam Brazil shall
sell, assign, give, pledge, encumber or otherwise transfer any Equity Quotas
owned by it, whether voluntarily or by operation of law, unless:

     (a)  such transfer complies with all applicable Brazil laws;

     (b)  the proposed transferee agrees in writing to assume all of the
          obligations of the transferring Quotaholder and to comply with this
          Agreement;

     (c)  the proposed transfer complies with the requirements of either Section
          8.2 or 8.3 below; and

     (d)  in the case of a proposed transfer pursuant to Section 8.3, (i) a
          period of three years has elapsed following the start of operations of
          the Company, and (ii) the proposed transferee is not a provider of
          irradiation systems, services and equipment in competition with
          Surebeam Corporation or Titan Surebeam Brazil, or is otherwise engaged
          in a business substantially similar to Surebeam Corporation or Titan
          Surebeam Brazil unless Surebeam Corporation or Titan Surebeam Brazil
          consents in writing to such transferee.

All sales, assignments, pledges or other transfers of ownership interests in the
Company not in compliance with the requirements of clauses (b), (c) or (d) above
shall require the prior majority approval of the Board of Directors.

8.2  PERMITTED TRANSFER. Either Tech Ion or Titan Surebeam Brazil may at any
time pledge, assign or transfer the Equity Quotas owned by it to any
Affiliate of such entity (a "PERMITTED TRANSFEREE"), provided that the
transferor entity guarantees in writing the performance by the transferee of
the transferred obligations and the transferee and transferor agree in
writing that should such transferee cease to be an Affiliate of transferor
the transferee will reassign its interest and obligations to the transferor
and the transferor will accept. No such assignment pledge or transfer under
this Section 8.2 shall relieve an entity of any of its obligations hereunder,
including, without limitation, those arising under Section 7.

8.3  SALE OF TECH ION. Tech Ion's Shareholders agree that they shall not sell or
otherwise transfer to any third party, all or any part of the capital stock of
Tech Ion without the prior written consent of Surebeam Corporation, which
consent shall not be unreasonably withheld. Tech Ion hereby agrees that it shall
not sell or otherwise transfer substantially all its assets without the prior
written consent of Surebeam Corporation, which consent shall not be unreasonably
withheld. In the event that Surebeam Corporation does not consent to such sales
or transfers, then Surebeam Corporation shall acquire such stock or assets of
Tech Ion under the same terms and conditions offered by the third party offeror,
PROVIDED, HOWEVER, that the third party offer is confirmable as being valid, at
no greater than fair market value, and under reasonable terms and conditions.

8.4  RIGHTS OF FIRST REFUSAL.

     (a)  Each Quotaholder of the Company hereby extends to the other
          Quotaholder a right of first refusal with respect to the sale of the
          Equity Quotas held by it or its Affiliates. The price of the Equity
          Quotas will be determined by an independent public accounting firm
          mutually agreed to by the Parties. Additionally, if at any time during
          the term hereof either Quotaholder or its respective Affiliates (the
          "OFFEROR PARTY") receives a bona fide offer from a third party ("THIRD
          PARTY OFFEROR") to purchase said Equity Quotas which offer is
          acceptable to the Offeror Party ("THIRD PARTY OFFER"), then the
          Offeror Party shall first offer to sell said Quotas to the other
          Quotaholder at the same price and an the same terms as have been
          offered by the Third Party Offeror.

     (b)  In the event either Quotaholder receives an unsolicited offer from a
          third party or parties for the purchase of such Quotaholder's Equity
          Quotas, the Quotaholder receiving such offer will promptly inform the
          other Quotaholder of the name, business and address of the third
          party.

     (c)  The Offeror Party's notice of the offer to the other Quotaholder shall
          set forth the name and address of the Third Party Offeror, the per
          quota price offered by the Third Party Offeror, the number of Equity
          Quotas to which the offer applies and the other terms of the Third
          Party Offer.

     (d)  The Offeror Party's offer shall remain effective for acceptance by the
          other Quotaholder (the "ACCEPTANCE PERIOD") for 45 days from the date
          of the Offeror Party's notice. During the Acceptance Period, the other
          Quotaholder may accept the offer to purchase all, and not only a part
          of, the Equity Quotas offered by the Offeror Party by giving written
          notice of such acceptance to the Offeror Party.

     (e)  If the other Quotaholder rejects or fails to accept such offer, the
          Offeror Party shall, subject to the prior written consent of such
          other Quotaholder, which consent shall not be unreasonably withheld,
          have the right, exercisable not later than 90 days following the
          expiration of the Acceptance Period, to consummate the sale of the
          offered quotas to the Third Party Offeror at a price not lower than,

                                       22

<PAGE>

          and on terms not more favorable than the Third Party Offer. If the
          Offeror Party does not consummate such sale within said 90-day period,
          such offered Equity Quotas shall again be subject in all respects to
          the terms, conditions, and restrictions provided in this Section 8.4.

     (f)  If the other Quotaholder agrees to purchase the offered Equity Quotas
          pursuant to this Section 8.4, the closing shall take place not later
          than thirty (30) days following the other Quotaholder's notice of
          acceptance. The time and place of the closing shall be mutually
          agreed.

9.  TERMINATION.

9.1 Any non-defaulting Party (the "INNOCENT PARTY") shall have the right to give
notice in writing as appropriate to the other Party (THE "DEFAULTING PARTY")
that the Innocent Party intends to exercise its right to call for the transfer
of the Defaulting Party's Equity Quotas to the Innocent Party in any of the
following events.

     (a)  material breach by the Defaulting Party of any of its obligations
          under this Agreement and failure by such Defaulting Party to remedy
          such breach (if capable of remedy) [...***...] of being required by
          the Innocent Party by notice so to do.

     (b)  a voluntary arrangement being proposed or approved or an
          administration order being made or a receiver or administrative
          receiver being appointed in respect of the Defaulting Party or of a
          substantial part of the Defaulting Party's assets or undertaking or a
          winding-up resolution or petition being passed or presented in
          relation to the Defaulting Party (otherwise than for the purposes of
          reconstruction or amalgamation) or any circumstances arising which
          entitle the Court or a creditor to appoint a receiver, administrative
          receiver or administrator or to present a winding-up petition or to
          make a winding-up order in respect of the Defaulting Party or other
          similar or equivalent action being taken against or by the Defaulting
          Party by reason of its insolvency or in consequence of debt

9.2 Within ninety (90) days of the Innocent Party giving notice under Section
9.1 of its intention to exercise its rights to call for the transfer of the
Defaulting Party's Equity Quotas to it, the Innocent Party shall have the
right by written notice to call upon the Defaulting Party to transfer its
Equity Quotas to the Innocent Party or any other person or entity designated
by the Innocent Party, at a value equal to such proportion of the Net Asset
Value of the Company as the number of Quotas held by the Defaulting Party
bears to the total number of issued Quotas. The Company's Auditors shall, by
reference to the most recently available quarterly accounts of the Company,
determine the Net Asset Value of the Company. The Auditors' valuation shall
be delivered to all Parties within thirty (30) days of the date of the notice
referred to in this Section.

<PAGE>

9.3   The transfer contemplated by this Section shall be completed within thirty
(30) days of the receipt of the Auditors' valuation; PROVIDED, HOWEVER, that if
either Party has commenced an arbitration of the issues relating to the alleged
material breach upon which such call for the transfer of the defaulting Party's
Equity Quotas is based, such transfer shall be held in abeyance pending the
issuance of the arbitral award and shall be subject to the terms of the arbitral
award.

9.4   This Agreement shall terminate automatically upon either Tech Ion or Titan
Surebeam Brazil ceasing to bold any Equity Quotas (other than in the case of a
transfer or assignment under Section 8.2), or upon a winding-up resolution being
passed or a winding-up order being made in respect of the Company. Termination
shall not affect the accrued rights of the parties hereunder. Termination shall
not affect those provisions of this Agreement of a continuing nature.

10.   FORCE MAJEURE, CHANGES IN LAW OR REGULATION

10.1  FORCE MAJEURE. Neither Party shall be liable for failure to perform its
obligations hereunder due to causes beyond its control, including but not

such change, then the Parties may cause the Company to wind up and terminate
this Agreement, and Tech Ion shall cooperate in passing any resolution necessary
in order to effect the same.

     same by post) or, where the parties expressly agree, by registered
     electronic mail, to the addresses set forth above or as may be changed by a
     Party from time to time upon written notice to the other Party. Any such

12.6  NO WAIVER. No relaxation, forbearance, delay or indulgence by either party
in enforcing any of the terms and conditions of this Agreement or the granting
of time by either party to the other shall prejudice affect or restrict the
rights and powers of such party hereunder nor shall any waiver by either party

12.7  DISPUTE RESOLUTION. In case of any dispute arising between the Parties
under or in connection with this Agreement or of any deadlock regarding an issue
submitted to the Board of Directors for approval, the Chairman of Titan Surebeam
Brazil and the Chairman of Tech Ion, or their designees, shall meet in person
and attempt to resolve the tie. If the tie is not resolved within thirty (30)
days of the meeting, then the matter shall be submitted to the Brazil-Canada
Chamber of Commerce, in Sao Paulo, Brazil, for arbitration in accordance with
the Brazilian Law. Each Party shall be entitled to elect 1 (one) arbitrator (and
a substitute for him/her) within 30 (thirty) days of submission of the matter to
arbitration. The 2 (two) arbitrators shall jointly designate within 30 (thirty)
days a third arbitrator to preside the arbitration. If either Party fails to
appoint an arbitrator or if the arbitrators fail to elect the third one, then
such arbitrator shall be designated by the President of the Brazil-Canada

and records of the arbitration shall be conducted and maintained in the English
language. The Parties agree that the award is to be considered as a settlement
of the dispute between them and shall accept it as the true expression of their
own determination in connection therewith. The Parties agree that either Party
may have the need to obtain immediate relief from the Judiciary. Therefore, the
filing for and obtainment of injunctive relief (or another type of remedy which
cannot be obtained from an arbitration tribunal under Brazilian law) in
connection with this Agreement shall be accepted, and shall not be considered a
breach hereof. In this case, the jurisdiction will be of the courts of the City
of Sao Paulo.
