                               4.4.3 Maximum Annual Royalties. Anything herein
to the contrary notwithstanding, the maximum amount Predix shall be obligated to
pay to Ramot under Section 4.4.1 as royalties on Net Sales generated during any
calendar year shall be [**********] dollars ($[*********]).

                     4.5 PAYMENT TERMS.

                               4.5.1 Payment. Predix shall make any payments
under Section 4.4 to Ramot in arrears within ninety (90) days from the end of
each quarter in which such payment accrues. Each royalty payment shall be
accompanied by a report for each country in the Territory in which sales of
Licensed Products occurred in the calendar quarter covered by such statement,
specifying: the gross sales and Net Sales in each country's currency; the
applicable royalty rate under this Agreement; the royalties payable in each
country's currency, including an accounting of deductions taken in the
calculation of Net Sales; the applicable exchange rate to convert from each
country's currency to United States Dollars under this Section 4.4; and the
royalties payable in United States Dollars. An officer of Predix shall sign each
such report, on behalf of Predix, certifying its completeness and accuracy.

                               4.5.2 Accounting. All payments hereunder shall be
made in United States dollars by wire transfer to a bank account designated by
Ramot. Conversion of foreign currency to United States dollars shall be made at
the conversion rate existing in the United States (as reported in The Wall
Street Journal) on the last business day of the applicable calendar quarter. If
The Wall Street Journal ceases to be published, then the rate of exchange to be
used shall be that reported in such other business publication of national
circulation in the United States as the Parties reasonably agree. Such payments
shall be without deduction of exchange, collection, or other charges.

                               4.5.3 Tax Withholding; Restrictions on Payment.
All payments hereunder shall be made free and clear of any taxes, duties,
levies, fees or charges, except for withholding taxes (to the extent
applicable). If applicable law requires that taxes be withheld from any amounts
due Ramot under this Agreement, Predix shall make any applicable withholding
payments due on behalf of Ramot and shall promptly provide Ramot with a
statement including the amount of tax withheld and justification therefore, and
such other written documentation regarding any such payment as available to
Predix relating to an application by Ramot for a foreign tax credit for such
payment. If by law, regulations or fiscal policy of a particular country in the
Territory, remittance of royalties in United States Dollars is restricted or
forbidden, written notice thereof shall promptly be given to Ramot, and payment
of the royalty shall be made by the deposit thereof in local currency to the
credit of Ramot in a recognized banking institution reasonably designated by
Ramot by written notice to Predix. Ramot shall be responsible for paying all
income taxes attributable to Ramot as a result of its receipt of funds
hereunder, to the extent applicable.

                               4.5.4 Late Payments. Any payments to be paid
under this Agreement that are not paid on or before the date such payments are
due under this Agreement shall bear interest at an annual interest, compounded
monthly, equal to [*****] percent ([*]%) above the London Interbank Offer Rate
(LIBOR) as determined for each month on the last business day of that month,
assessed from the day payment was initially due until the date of payment.

                     4.6 REPORTS; RECORDS RETENTION; REVIEW.

                               4.6.1 Reporting. Predix undertakes to notify
Ramot promptly following the grant of a Sublicense or the execution of an
agreement for the provision of Services. Each such notification shall include a
brief summary of the financial terms of such transaction.

                               4.6.2 Reports. In addition to the reports under
Section 4.5.1, commencing with the receipt of the first Sublicense Income or
Service Income, Predix shall provide Ramot with quarterly reports setting forth
all Sublicense Income and Service Income received by Predix and its Affiliates.
In addition, within sixty (60) days after the end of each calendar year, Predix
shall furnish Ramot with a written report on the progress of its, its
Affiliate's and Sublicensees' efforts during the prior year to develop and
commercialize Licensed Products, including without limitation research and
development efforts, efforts to obtain Regulatory Approval and marketing
efforts. All reports provided by Predix under Section 4.6.1 and Section 4.6.2
shall be signed by the chief financial officer or chief business officer of
Predix certifying on behalf of Predix the accuracy and completeness of the
information provided therein.

                               4.6.3 Records. Commencing as of the date of the
receipt of the first Net Sales, Sublicense Income or Service Income hereunder,
Predix and its Affiliates shall keep for at least three (3) years from the end
of the calendar year to which they pertain complete and accurate records of
sales by Predix or its Affiliates, as the case may be, of each Licensed Product
and of Sublicense Income and Service Income received, in sufficient detail to
allow the accuracy of the payments hereunder to be confirmed.

                               4.6.4 Review. Subject to the other terms of this
Section 4.6.4, at the request of Ramot, which shall not be made more frequently
than [*****************] during the Term, upon reasonable prior notice from
Ramot, and at the expense of Ramot, except as otherwise provided herein, Predix
and its Affiliates shall permit an independent certified public accountant
selected by Ramot and reasonably acceptable to Predix to inspect, during regular
business hours, the relevant records required to be maintained by Predix and its
Affiliates under this Section 4.6. In every case the accountant must have
previously entered into a confidentiality agreement with both Parties
substantially similar to the provisions of Article 5 and limiting the disclosure
and use of such information by such accountant to authorized representatives of
the Parties and the purposes germane to this Section 4.6. Results of any such
review shall be binding on both Parties absent manifest error. Ramot agrees to
treat the results of any such accountant's review as Confidential Information of
Predix subject to the terms of Article 5. If any review reveals a deficiency in
the calculation and/or payment of royalties by Predix, then Predix shall
promptly pay Ramot the amount remaining to be paid, and if such underpayment is
by [*****] percent ([*]%) or more of the amount payable during the period under
audit, Predix shall [**********************************************************]

shall not disclose the Confidential Information of the other Party except on a
need-to-know basis to such Party's directors, officers and employees, and to
such Party's consultants, to the extent such disclosure is necessary in
connection with such Party's activities as expressly authorized by this
Agreement. In addition to the foregoing, Predix may disclose Confidential
Information of Ramot to any Sublicensees that are bound by restrictions on
disclosure that are at least as stringent as those set forth herein. To the
extent that disclosure to any person is authorized by this Agreement, prior to
disclosure, a Party shall obtain, or shall have obtained prior to the date of
this Agreement, written agreement of such person pursuant to which such person
is bound to hold in confidence and not disclose, use or grant the use of the
Confidential Information of the other Party except as expressly permitted under
this Agreement. Each Party shall notify the other Party promptly upon discovery
of any unauthorized use or disclosure of the other Party's Confidential
Information.

                     5.2 Terms of Agreement. Neither Party shall disclose any
terms or conditions of this Agreement to any Third Party without the prior
consent of the other Party; provided, however, that a Party may disclose the
terms or conditions of this Agreement: (a) on a need-to-know basis to its legal
and financial advisors to the extent such disclosure is reasonably necessary in
connection with such Party's activities as expressly permitted by this
Agreement, and (b) to a Third Party who is subject to confidentiality
obligations similar to those set forth herein in connection with: (i) an equity
investment in or by such Party, (ii) a merger, consolidation or similar
transaction involving such Party, (iii) the negotiation of a sublicense of
rights granted hereunder or (iv) the sale of all or substantially all of the
assets of such Party. Notwithstanding the foregoing, prior to execution of this
Agreement, the Parties have agreed upon the text of one or more press releases
that describe the terms and conditions of this transaction, and each Party may
disclose such information, as modified by mutual written agreement the Parties,
without the consent of the other Party.

                     5.3 Permitted Disclosures. The confidentiality obligations
under this Article 5 shall not apply to the extent that a Party is required to
disclose information by applicable law, regulation or order of a governmental
agency or a court of competent jurisdiction; provided, however, that such Party
shall provide written notice thereof to the other Party, consult with the other
Party with respect to such disclosure and provide the other Party sufficient
opportunity to object to any such disclosure or to request confidential
treatment thereof.

MAINTENANCE OF PATENT RIGHTS

                     6.1 OWNERSHIP OF TECHNOLOGY. Subject to the terms and
conditions set forth herein, including without limitation the license granted in
Section 2.1, Ramot shall own all right, title and interest in and to any and all

hereunder by implication or estoppel or by any means other than express grant.

                     6.2 OWNERSHIP OF LICENSED PRODUCTS. Predix shall own all

<PAGE>
                               6.3.1 Licensed Patent Rights. Ramot and Predix
shall consult each other regarding the preparation, filing and prosecution of
all patent applications, and the maintenance of all patents, included within the
Licensed Patent Rights, including, without limitation, the content, timing and
jurisdiction of the filing of such patent applications and their prosecution,
and other details. Predix shall be responsible for preparing, filing,
prosecuting, obtaining and maintaining, at its sole cost and expense, using
patent counsel reasonably acceptable to Ramot, all Licensed Patent Rights, in
the name of Ramot, with the goal of obtaining and maintaining the Licensed
Patents in a manner that will provide the maximum economic advantage and return
to the Parties under this Agreement. Predix: (i) will provide Ramot with a copy
of any proposed patent application within such Licensed Patent Rights for review
and comment reasonably in advance of filing, and (ii) will keep Ramot informed
of the status of such filing, prosecution and maintenance, including, without
limitation, by providing Ramot with copies of all communications received from
or filed in patent office(s) with respect to such filing, and by providing
Ramot, a reasonable time prior to taking or failing to take any action that
would affect the scope or validity of any such filing (including the
substantially narrowing, cancellation or abandonment of any claim(s) without
retaining the right to pursue such subject matter in a separate application, or
the failure to file or perfect the filing of any claim(s) in any country), with
prior written notice of such proposed action or inaction so that Ramot has a
reasonable opportunity to review and comment. Predix shall not take any such
action that would affect the scope of validity or any such filing without the
prior written consent of Ramot. If Predix fails to undertake the filing(s),
prosecution, protection and/or maintenance of any patent application, patent or
submission within the Licensed Patent Rights, without the prior consent of
Ramot, all claims included in such patent applications, patents and/or
submissions shall be deemed Valid Claims within the Licensed Patent Rights for
purposes of Section 1.17 until such times as the relevant patents would have
expired had they continued to their fullest term.

                               6.3.2 Other Patent Rights. Except as set forth in
Section 6.3.1, each Party shall be responsible for preparing, filing,
prosecuting, obtaining and maintaining, at its sole cost, expense and
discretion, all of its own Patent Rights. Predix undertakes to notify Ramot, on
an annual basis, of the filing by or on behalf of Predix or any of its
Affiliates of any priority patent application relating to or covering an actual
or potential Licensed Product. Each such notification shall include a brief
summary of the invention disclosed in such application.

                     6.4 NOTICE OF INFRINGEMENT. If, during the Term, either
Party learns of any actual, alleged or threatened infringement by a Third Party
of any Licensed Patent Rights, such Party shall promptly notify the other Party
and shall provide such other Party with available evidence of such infringement.

                     6.5 INFRINGEMENT OF PATENT RIGHTS. Predix, after
consultation with Ramot, shall have the first right, but not the obligation and
with legal counsel of its own choice, to bring suit, or take other appropriate
legal action, against any actual, alleged or threatened infringement of the
Licensed Patent Rights. If Ramot is joined as a party plaintiff in any such
suit, Ramot shall have the right to approve or disapprove of the counsel
selected by Predix to represent Predix and Ramot, such approval not to be
unreasonably withheld. The expenses of such suit or suits that Predix elects to
bring, including any expenses of Ramot incurred in conjunction with the
prosecution of such suits or the settlement thereof, shall be paid for entirely
by Predix and Predix shall hold Ramot free, clear and harmless from and against
any and all costs of such litigation, including attorney's fees. Predix shall
not compromise or settle such litigation without

the prior written consent of Ramot, which consent shall not be unreasonably
withheld or delayed. Ramot shall have the right, at its own expense, to be
represented in any such action by Predix by counsel of Ramot's own choice. If
Predix does not file any action or proceeding against any such infringement
within three (3) months after the earlier of: (i) Predix's notice to Ramot under
Section 6.4 above, (ii) Ramot's notice to Predix under Section 6.2 above, or
(iii) a written request from Ramot to take action with respect to such
infringement, then Ramot shall have the right, but not the obligation, at its
own expense, to bring suit, or take other appropriate legal action, against such
actual, alleged or threatened infringement, with legal counsel of its own
choice, but shall not be permitted to settle any such suit without the prior
consent of Predix, which consent shall not be unreasonably withheld. Any
damages, monetary awards or other amounts recovered, whether by judgment or
settlement, pursuant to any suit, proceeding or other legal action taken under
this Section 6.3, shall be applied as follows:

                               (a) First, to reimburse the Parties for their
respective costs and expenses (including reasonable attorneys' fees and costs)
incurred in prosecuting such enforcement action; and

                               (b) Second, any amounts remaining shall be
allocated as follows: (a) if Ramot is the Party bringing such suit or proceeding
or taking such other legal action, [***********] percent ([****]%)
[*********************], (b) if Predix is the Party bringing such suit or
proceeding or taking such other legal action, [**********] percent ([****]%)
[******************], and (c) if the suit is brought jointly, [*****] percent
([***]%) [********************].

If a Party brings any such action or proceeding hereunder, the other Party
agrees to be joined as Party plaintiff if necessary to prosecute such action or
proceeding, and to give the Party bringing such action or proceeding reasonable
assistance and authority to file and prosecute the suit; provided, however, that
neither Party shall be required to transfer any right, title or interest in or
to any property to the other Party or any Third Party to confer standing on a
Party hereunder.

                     8.1 INDEMNIFICATION. Predix shall indemnify, defend and
hold harmless Ramot, its Affiliates and their respective governors, directors,
officers, employees, stockholders and agents and their respective successors,
heirs and assigns (the "Ramot Indemnitees") from and against any liability,
damage, loss or expense (including reasonable attorneys' fees and expenses of
litigation) incurred by or imposed upon such Ramot Indemnitees, or any of them,
in connection with any Third Party claims, suits, actions, demands or judgments,
including, without limitation, personal injury and product liability matters, to
the extent arising out of: (a) the development, testing, production,
manufacture, supply, promotion, import, sale or use by any person of any
Software Product or Licensed Product (or any component thereof) manufactured or
sold by Predix or any Affiliate or Sublicensee under this Agreement, (b) the use

the right to settle the claim solely for monetary consideration, provided that
no settlement shall be made without the consent of Ramot, which consent shall
not be unreasonably withheld) and shall cooperate as requested (at the expense
of Predix) in the defense of the claim. The indemnification obligations under
Article 8 shall not apply to any harm suffered as a direct result of any delay
in notice to Predix hereunder or to amounts paid in settlement of any claim,
demand, action or other proceeding if such settlement is effected without the
consent of Predix, which consent shall not be withheld or delayed unreasonably.
The Indemnitee, its employees and agents, shall reasonably cooperate with Predix

                               Subject to the other terms of this Agreement,
this Agreement and the rights and options granted herein may be terminated
by either Party upon any material breach by the other Party of any material
obligation or condition, effective thirty (30) days after giving written notice
to the breaching Party of such termination in the case of a payment breach and
ninety (90) days after giving written notice to the breaching Party of such
termination in the case of any other breach, which notice shall describe such
breach in reasonable detail. The foregoing notwithstanding, if such default or
breach is cured or remedied or shown to be non-existent within the aforesaid
thirty (30) or ninety (90) day period, the notice shall be automatically
withdrawn and of no effect. However, prior to giving any notice of termination
for breach, the Parties shall first attempt to resolve any disputes as to the
existence of any breach as set forth in Article 10.

Party files for protection under bankruptcy laws, makes an assignment for the
benefit of creditors, appoints or suffers appointment of a receiver or trustee

days of the filing thereof, then the other Party may terminate this Agreement
effective immediately upon written notice to such Party.

termination of this Agreement by Ramot under Section 9.2, as of the effective
date of such termination all relevant licenses and sublicenses granted by Ramot
to Predix hereunder shall terminate automatically. Notwithstanding the
foregoing: (a) no such termination of this Agreement shall be construed as a
termination of any valid sublicense of any Sublicensee hereunder, and thereafter
each such Sublicensee shall be considered a direct licensee of Ramot, provided
that (i) such Sublicensee is then in full compliance with all terms and
conditions of its sublicense, (ii) all accrued payments obligations to Ramot
have been paid, and (iii) such Sublicensee agrees in writing to assume all
applicable obligations of Predix under this Agreement, and (b) Predix and its
Affiliates and Sublicensees shall have the right, for six (6) months or such
longer time period (if any) on which the Parties mutually agree in writing, to
sell or otherwise dispose of all Licensed Products then on hand, with royalties
to be paid to Ramot on all Net Sales of such Licensed Products as provided for
in this Agreement.

Section 9.4), exclusive license in the Territory under the Licensed Patent
Rights and Licensed Technology, to Develop, have Developed, make, have made,
use, have used, sell, offer for sale, have sold, import and have imported any
