                                   AGREEMENT

          The parties to this Agreement agree as follows:

SECTION 1.    DESCRIPTION OF TRANSACTION.

        1.1   Purchase and Sale.  Subject to the terms and conditions of this
Agreement, on the Closing Date (as defined below), the Sellers shall sell,
transfer, assign, convey and deliver to Terayon, and Terayon shall purchase from
the Sellers such Shares, in each case, free and clear of all Liens. The closing
of the purchase and sale (the "Closing") shall take place at the offices of
Naschitz Brandes & Co., 5 Tuval Street, Tel Aviv, Israel at 10:00 a.m., on
February ___, 2000 or such later business day on which all the conditions set
forth in Section 6 and 7 have been satisfied or waived, or on such other date,
time and place as the parties may mutually agree (the "Closing Date").  At the
Closing, the Sellers shall cause the Company to deliver to Terayon one or more
instruments representing the Shares, and Terayon
<PAGE>

(i) shall issue the Share Consideration (as defined in Section 1.3 below) to the
Sellers' Representative (as defined in Section 10.1 below) for distribution to
the Sellers in accordance with the column in Schedule A captioned "Share
Consideration", (ii) shall pay the Cash Payment to the Sellers' Representative
for distribution to the Sellers in accordance with the column in Schedule A
captioned "Cash Payment" and, (iii) shall deposit the Escrow Shares (as defined
below) with the Escrow Agent, which amounts together represent the aggregate
Purchase Consideration payable to the Sellers hereunder.

  1.2     Further Assurances. If, at any time after the Closing Date, Terayon
shall consider or be advised that any deeds, bills of sale, assignments or
assurances or any other acts or things are reasonably necessary, desirable or
proper (a) to vest, perfect or confirm, of record or otherwise, in Terayon, its
right to, and title or interest in, the Shares or (b) otherwise to carry out the
purposes of this Agreement, Terayon shall so advise the Company in writing, and
the Company thereupon shall execute and deliver all such deeds, bills of sale,
assignments and assurances and do all such other acts and things reasonably
necessary, desirable or proper to vest, perfect or confirm its right, title or
interest in, to or under the  Shares, and otherwise to carry out the purposes of
this Agreement.

  1.3     Purchase Consideration.  The consideration for the Shares shall be
775,000 shares of Common Stock of Terayon (the "Terayon Shares").  In accordance
with Section 1.1, on the Closing Date, Terayon shall issue to the Sellers the
Terayon Shares (the "Share Consideration"), of which 77,500 shares of Common
Stock of Terayon (the "Escrow Shares") shall be deposited with the Escrow Agent
to be held in the Escrow Fund and shall be available to satisfy the
indemnification obligations as provided in Section 9. In lieu of a portion of
the Share Consideration, as set forth in Section 1.4 below, Terayon shall be
entitled to pay the Sellers cash in an amount of up to two hundred and fifty

forth in Section 1.3 above shall be made by Terayon to the Sellers'
Representative on the Closing Date. All cash payments made by Terayon to the
Sellers' Representative on the Closing Date shall be made by wire transfer of
immediately available funds to the account specified by the Seller in writing to
Terayon at least two (2) business days prior to the Closing Date (the
"Account"). The Cash Payment shall reduce the Share Consideration by such number
of Terayon Shares, the value of which (calculated using the average closing
prices of the shares of Terayon Common Stock, as reported on the Nasdaq National
Market for the fifteen consecutive trading days immediately preceding the date
which is three days prior to the Closing Date) shall be equal to the Cash
Payment.

  1.5     Seller Waivers.  Each Seller hereby waives and releases, effective as
of the Closing, any and all rights, claims and causes of action assertable
against the Company in respect of its ownership of any securities of the Company
and any and all agreements
<PAGE>

between such Seller and the Company, which agreements shall automatically
terminate as of the Closing Date.

  1.6       Accounting Treatment.  For accounting purposes, the transaction
contemplated by this Agreement is intended to be treated as a "purchase."

and the number of Class A Ordinary Shares covered by each Option are set forth

            (b) At the Closing, all Options shall be canceled, and in
consideration of such cancellation, Terayon shall deposit such number of options
to purchase Common Stock ("Terayon Options") indicated opposite such Option
Holder's name on Schedule A in a Retention Account, which shall be created
specifically for such purpose. The Terayon Options shall be released to the
Option Holders upon and subject to the terms and conditions set forth in
Schedule 1.7(b). Prior to the Closing, no Option Holder shall exercise or
transfer any Options prior to the Closing.

            (c) As soon as practicable following the date hereof and in any
event prior to the Closing, the Company shall secure the written agreement, in
form and substance reasonably acceptable to Terayon, of each Option Holder to
the terms and conditions of this Agreement (the "Option Holder Consent Letter
and Counterpart Signature Page"). For the avoidance of doubt, the Share
Consideration shall include the total number of shares of Common Stock to be

Section 9.  Indemnification, Etc.

     9.1    Survival of Representations, Etc.

            (a) The representations and warranties made by the Company
(including the representations and warranties set forth in Section 2 and the
representations and warranties set forth in the Company Closing Certificate)
shall survive the Closing and shall expire on the 12-month anniversary of the
Closing Date; provided, however, that if, at any time prior to the 12-month
anniversary of the Closing Date, any Indemnitee (acting in good faith) delivers
to the Sellers' Representative a written notice alleging the existence of an
inaccuracy in or a breach of any of the representations and warranties made by
the Company (and setting forth in reasonable detail the basis for such
Indemnitee's belief that such an inaccuracy or breach may exist) and asserting a
claim for recovery under Section 9.2 based on such alleged inaccuracy or breach,
then the claim asserted in such notice shall survive the 12-month anniversary of
the Closing until such time as such claim is fully and finally resolved.

            (b) The representations, warranties, covenants and obligations of
the Company, and the rights and remedies that may be exercised by the
Indemnitees, shall not be limited or otherwise affected by or as a result of any
information furnished to, or any investigation made by or knowledge of, any of
the Indemnitees or any of their Representatives.

            (c) For purposes of this Agreement, each statement or other item of
information set forth in the Disclosure Schedule or in any update to the
Disclosure Schedule shall be deemed to be a representation and warranty made by
the Company in this Agreement.

            (d) The representations and warranties made by Terayon (including
the representations and warranties set forth in Section 3 and the
representations and warranties set forth in Terayon Closing Certificate) shall
survive the Closing and shall expire on the 12-month anniversary of the Closing
Date; provided, however, that if, at any time prior to the 12-month anniversary
of the Closing Date, the Sellers' Representative (acting in good faith) shall
deliver to Terayon a written notice alleging the existence of an inaccuracy in
or a breach of any of the representations and warranties made by Terayon (and
setting forth in reasonable detail the basis for the Sellers belief that such an
inaccuracy or breach may exist) and asserting a claim for recovery under Section
9.2 based on such alleged inaccuracy or breach, then the claim asserted in such
notice shall survive the 12-month anniversary of the Closing until such time as
such claim is fully and finally resolved.

            (e) The representations, warranties, covenants and obligations of
Terayon, and the rights and remedies that may be exercised by the Sellers, shall
not be limited or otherwise affected by or as a result of any information
furnished to, or any investigation made by or knowledge of, the Sellers.
<PAGE>

  9.2   Indemnification.

        (a) From and after the Closing Date (but subject to Section 9.1(a)), the
Indemnitees may seek indemnification first from the Escrow Fund and only
thereafter from each of the Sellers, severally but not jointly and to the extent
of such Seller's pro rata shareholdings in the Company, for any Damages (other
than consequential damages) that are suffered or incurred by any of the
Indemnitees or to which any of the Indemnitees may otherwise become subject
(regardless of whether or not such Damages relate to any third-party claim) and
which are from or as a result of, or are connected with:  (i)  any inaccuracy in
or breach of any representation or warranty set forth in Section 2 or in the
Company Closing Certificate; (ii) any inaccuracy in or breach of any
representation or warranty set forth in Section 2; (iii) any breach of any
covenant or obligation of the Company (including the covenants set forth in
Sections 4 and 5);or (iv) any Legal Proceeding relating to any inaccuracy or
breach of the type referred to in clause "(i)" or "(ii)" above (including any
Legal Proceeding commenced by any Indemnitee for the purpose of enforcing any of
its rights under this Section 9).

        (b) Each of the Sellers and the Company acknowledges and agrees that, if
the Company suffers, incurs or otherwise becomes subject to any Damages as a
result of or in connection with any inaccuracy in or breach of any
representation, warranty, covenant or obligation, then (without limiting any of
its rights as an Indemnitee) Terayon shall also be deemed, by virtue of its
ownership of the stock of the Company, to have incurred Damages as a result of
and in connection with such inaccuracy or breach.

  9.3   Defense of Third Party Claims.  In the event of the assertion or
commencement by any Person of any claim or Legal Proceeding (whether against the
Sellers, against Terayon or against any other Person) with respect to which any
of the Indemnitees shall have the right to seek indemnification pursuant to this
Section 9, Terayon shall have the right, at its election, to proceed with the
defense of such claim or Legal Proceeding on its own.  If Terayon so proceeds
with the defense of any such claim or Legal Proceeding:

        (a) all reasonable expenses relating to the defense of such claim or
Legal Proceeding shall be borne and paid out of the Escrow Fund;

        (b) Terayon shall have the right to settle, adjust or compromise such
claim or Legal Proceeding with the consent of the Sellers' Representative;
provided, however, that such consent shall not be unreasonably withheld.

  Terayon shall give the Sellers' Representative prompt notice of the
commencement of any such Legal Proceeding against Terayon or the Company;
provided, however, that any failure on the part of Terayon to so notify the
Sellers' Representative shall not limit any of the rights of the Indemnitees
under this Section 9 (except to the extent such failure materially prejudices
the defense of such Legal Proceeding).

        (c) From and after the Closing Date (but subject to Section 9.1(d)), any
Seller may seek indemnification from Terayon for any Damages (other than
consequential
<PAGE>

damages) that are suffered or incurred by such Seller or to which such Seller
may otherwise become subject (regardless of whether or not such Damages relate
to any third-party claim) and which arise from or as a result of, or are
directly connected with: (i) any inaccuracy in or breach of any representation
or warranty set forth in Section 3; (ii) any inaccuracy in or breach of any
representation or warranty set forth in Section 3 as if such representation and
warranty had been made on and as of the Closing Date; or (iii) any Legal
Proceeding relating to any inaccuracy or breach of the type referred to in
clause "(i)" or "(ii)" above (including any Legal Proceeding commenced by any
Seller for the purpose of enforcing any of its rights under this Section 9);
provided, however, that the amount of indemnification sought by the Sellers may
not exceed US$60 million.

     9.4  Exercise of Remedies by Indemnitees Other Than Terayon.  No Indemnitee
(other than Terayon or any successor thereto or assign thereof) shall be
permitted to assert any indemnification claim or exercise any other remedy under
this Agreement unless Terayon (or any successor thereto or assign thereof) shall
have consented to the assertion of such indemnification claim or the exercise of
such other remedy.

     9.5  Limitations on Indemnification.

          (a) Except as specifically set forth herein, the maximum amount of
indemnifiable Damages that may be recovered from the Sellers arising out of or
resulting from Section 9.2(a) shall be an amount equal to US$60 million, and in
no event shall any Seller have any indemnification liability under this
Agreement greater than his, her or its portion of the Purchase Consideration,
and the total indemnification liability of the Sellers under this Agreement
shall be allocated to each Seller based on such Seller's proportionate share of
the Purchase Consideration.

          (b) Notwithstanding anything to the contrary contained in this
Agreement, no Indemnitee shall be entitled to seek indemnification from the
Sellers under this Agreement with respect to any Damages arising out of or
resulting from Section 9.2(a), until the aggregate amount of such Damages
exceeds one hundred thousand US dollars ($100,000), and where such damages
exceed one hundred thousand US dollars ($100,000), the Indemnitees shall be
entitled to indemnification in full (with no deduction of the one hundred
thousand US dollars ($100,000)), subject to the provisions of Section 9.5(a).

          (c) Notwithstanding anything to the contrary contained in this
Agreement, the maximum amount of indemnifiable Damages that may be recovered
from Terayon arising out of or resulting from Section 9.2(c) shall be an amount
equal to US$60 million.

          (d) Notwithstanding anything to the contrary contained in this
Agreement, the Sellers shall not be entitled to seek indemnification from
Terayon under this Agreement with respect to any Damages arising out of or
resulting from Section 9.2(c), until the aggregate amount of such Damages
exceeds one hundred thousand US dollars ($100,000), and where such damages
exceed one hundred thousand US dollars ($100,000), the Indemnitees shall be
entitled to indemnification in full (with no deduction of the one hundred
<PAGE>

thousand US dollars ($100,000)), subject to the provisions of Section 9.5(c).

     9.6  Exclusive Remedies.  Terayon acknowledges and agrees that its sole and
exclusive remedy (except in the case of fraud, in which case Terayon reserves
all rights available to it under the law with respect to the party committing
such fraud) with respect to any and all claims relating to the subject matter of
this Agreement and the other agreements, documents and certificates specifically
contemplated by this Agreement shall be pursuant to the indemnification
provisions set forth in this Section 9 and specific performance as contemplated
by Section 10.11 below.

     9.7  Prospectus Indemnification.  Notwithstanding anything to the contrary
in this Agreement, in the event any shares of Common Stock are included in a
registration statement of Terayon:

          (a) To the extent permitted by law, Terayon will indemnify and hold
harmless each of the Sellers, the, officers, directors and legal counsel of each
of the Sellers, any underwriter (as defined in the Securities Act) for each of
the Sellers and each person, if any, who controls each of the Sellers or
underwriter within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the Securities Act, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation") by Terayon: (i)
any untrue statement of a material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, (ii) the omission to state
therein a material fact required to be stated therein, or necessary to make the
statements therein not misleading, or (iii) any violation or alleged violation
by Terayon of the Securities Act, the Exchange Act, any state securities law or
any rule or regulation promulgated under the Securities Act, the Exchange Act or
any state securities law in connection with the offering covered by such
registration statement; and Terayon will reimburse each of the  Sellers, officer
or director, underwriter or controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided however, that the
indemnity agreement contained in this Section 9.7(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of Terayon, which consent shall not
be unreasonably withheld, nor shall Terayon be liable in any such case for any
such loss, claim, damage, liability or action to the extent that it arises out
of or is based upon a Violation which occurs in reliance upon or in conformity
with written information furnished expressly for use in connection with such
registration by each of the Sellers, partner, officer, director, underwriter or
controlling person of each of the Sellers.

          (b) To the extent permitted by law, each of the Sellers will, if
Common Stock held by such Seller are included in the securities as to which such
registration qualifications or compliance is being effected, indemnify and hold
harmless Terayon, each of its directors, its officers, and legal counsel and
each person, if any, who controls Terayon within the meaning of the Securities
Act and any underwriter selling securities under such
<PAGE>

registration statement, against any losses, claims, damages or liabilities
(joint or several) to which Terayon or any such director, officer, controlling
person, or underwriter may become subject under the Securities Act, the Exchange
Act or other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon or in conformity with written information
furnished by such Seller specifically for use in connection with such
registration; and such Seller will reimburse any legal or other expenses
reasonably incurred by Terayon or any such director, officer, controlling person
or underwriter in connection with investigating or defending any such loss,
claim, damage, liability or action if it is judicial determined that there was
such a Violation; provided, however, that the indemnity agreement contained in
this Section 9.7(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of such Seller, which consent shall not be unreasonably withheld.

          (c) Promptly after receipt by an indemnified party under this Section
9.7 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 9.7, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding.  The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 9.7, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 9.7.

          (d) If the indemnification provided for in this Section 9.7 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the Violation(s) that resulted in such loss, claim, damage or
liability, as well as any other relevant equitable considerations.  The relative
fault of the indemnifying party and of the indemnified party shall be determined
by a court of law by reference to, among other things, whether the untrue
statement of a material fact or the omission to state a material fact relates to
information supplied by the indemnifying party or by the indemnified party and
the parties' relative intent, knowledge, access to information and opportunity
to correct or
<PAGE>

prevent such statement or omission.

            (e) The obligations of Terayon and each of the Sellers under this
Section 9.7 shall survive completion of any offering of Common Stock in a
registration statement and the termination of this Agreement.  No indemnifying
party, in the defense of any such claim or litigation, shall, except with the
consent of each indemnified party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such indemnified party of a release from
all liability in respect to such claim or litigation.

Section 10. Miscellaneous Provisions.

     10.1   Sellers' Representative. Mr. Robert Levy is hereby designated as the

this Agreement, all of which actions and omissions shall be binding on each of
the Sellers. If the Sellers' Representative shall die, become disabled or
otherwise be unable to fulfill his responsibilities as agent of the Sellers,

convertible securities) shall, within ten days after such death or disability,
appoint a successor agent and, promptly thereafter, shall notify Terayon of the
identity of such successor. Any such successor shall become the "Sellers'
Representative" for purposes of this Agreement. The Sellers hereby authorize the
Sellers' Representative to pay all reasonable and documented legal fees and
expenses incurred by the Company and the Sellers (as further described in
Section 10.3 below) from the Purchase Consideration prior to the distribution of
the Purchase Consideration to the Sellers. The Sellers hereby agree to transfer
to the Sellers' Representative such additional cash amounts as shall be
determined by the Sellers' Representative are necessary to pay all legal fees
and expenses incurred by the Company and the Sellers (as further described in
Section 10.3 below).

  10.2.  Further Assurances.  Each party hereto shall execute and cause to be
delivered to each other party hereto such instruments and other documents, and
shall take such other actions, as such other party may reasonably request (prior
to, at or after the Closing) for the purpose of carrying out or evidencing any
of the transactions contemplated by this Agreement.

  10.3   Fees and Expenses.  Each of Terayon and the Company  shall bear and
pay all fees, costs and expenses (including legal fees and accounting fees) that
have been incurred or that are incurred by such party (and, in the case of the
Sellers, also by the Company) in connection with the transactions contemplated
by this Agreement, including all fees, costs and expenses incurred by such party
in connection with or by virtue of (a) the investigation and review conducted by
Terayon and its Representatives with respect to the Company's business (and the
furnishing of information to Terayon and its Representatives in connection with
such investigation and review), (b) the negotiation, preparation and review of
this Agreement (including the Disclosure Schedule) and all agreements,
certificates, opinions and other instruments and documents delivered or to be

hereto agree that the Closing may be effected by facsimile. At the Closing, the
Seller shall deliver to the Purchaser one or more instruments representing the
Seller's ownership of the Purchased Assets and their delivery to the Purchaser,
and the Purchaser shall (i) cause Terayon to issue the Acquisition Shares (as
defined below) to the Seller, (ii) pay the cash payment to the Seller, and (iii)
cause Terayon to deposit the Escrow Shares (as defined below) with the Escrow
Agent, which amounts together represent the aggregate Purchase Consideration (as
defined below) payable to the Seller hereunder. At the Closing, the Purchase
Consideration shall be delivered to Ravillan, Volovelsky, Dinstein, Sneh & Co.
and shall be released by Ravillan, Volovelsky, Dinstein, Sneh & Co. to the
Seller only after the Permitted Lien has finally been removed.


     2.2  Purchase Consideration.  As consideration for the sale of the
Purchased Assets to Purchaser, at the Closing, Purchaser shall cause Terayon to
issue to Seller and/or its designee(s) pursuant to a letter of designation, as
set forth in Section 2.2A hereof, and shall deliver to the Seller, the number of
shares of Common Stock of Terayon (the "Acquisition Shares") equal to
$35,568,470 in value (i.e., 185,031 shares), calculated using the average of the
closing price of Terayon Common Stock, as reported on the Nasdaq National
Market, for the 30 consecutive trading days immediately preceding the date
hereof, and pay the Seller cash in the amount of $1,480,263 to cover certain
accrued expenses and liabilities of the Company as set forth in Schedule 2.2. In

reasonably acceptable to Purchaser) evidencing said expenses and liabilities
(the "Cash Payment" and collectively with the Acquisition Shares, the "Purchase
Consideration"). In accordance with Section 2.1, on the Closing Date, the
Purchaser shall cause Terayon to issue to the Seller and/or its designee(s) the
Acquisition Shares, of which shares of Common Stock of Terayon with a value
equal to one million and seven hundred and fifty thousand US Dollars
($1,750,000) (the "Escrow Shares")

                                      3.
<PAGE>

shall be deposited with the Escrow Agent to be held in the Escrow Fund and shall
be available to satisfy the indemnification obligations as provided in Section 9
below.

     2.2A For purposes of this Agreement, Terayon shall, at the Seller's
request, issue shares, in respect of the Purchase Consideration, the Additional
Consideration or the Additional Shares, in the name of designee(s) of the
Seller, provided that (i)Terayon shall receive, at least 10 days prior to the
issuance date of such shares, a designation letter, duly signed by the Seller
and the designee, specifying the Seller's request and the designee's consent
that the shares be issued in the name of such designee; (ii) such designation
shall not affect the Seller's obligations to Terayon and the Purchaser under
this Agreement, including without limitation the Seller's indemnification
obligations and the Seller's representations and warranties under this
Agreement; and (iii) the Seller and the designee shall have complied with all
legal requirements applicable to the transfer of cash and/or property to the
designee. For the purposes hereof, the opinion of any of Ravillan, Volovelsky,
Dinstein, Sneh & Co., Arthur Andersen (Luboschitz, Kasirer), or any other expert
acceptable to the Purchaser or Terayon, stating that all the legal requirements
have been complied with, shall constitute sufficient evidence of such
compliance.

     2.3  The Measurement Date and Additional Consideration. (a)
Notwithstanding the aforementioned in Sub-Section 2.2, subject to the terms
below, in the event that the Measurement Date Share Price (as defined below) is
less than the value of a share of the Common Stock of Terayon on the date hereof
(calculated in accordance with Section 2.2 above, using the average of the
closing price of Terayon Common Stock, as reported on the Nasdaq National
Market, for the 30 consecutive trading days immediately preceding the date
hereof (the "Contract Price")), the Purchaser shall, within ten days following
the date on which the registration statement pursuant to which the Registrable
Shares (as defined in Section 6.2 below) are registered for trading becomes
effective (the "Measurement Date"), pay to the Seller additional consideration
(the "Additional Consideration") which shall be equal to: (i) the aggregate
number of  Registrable Shares held by Seller and/or its designee(s), any of its
shareholders, any of their respective affiliates and in the Escrow Fund on the
Measurement Date multiplied by (ii) the difference between the Contract Price
and the Measurement Date Share Price.

          (b) The Measurement Date Share Price. The Measurement Date Share Price
shall be equal to the average of the closing sale prices of the shares of Common
Stock of Terayon as reported on the Nasdaq National Market for the five (5)
consecutive trading days immediately following the Measurement Date.

          (c) The Purchaser shall be entitled to pay the above Additional
Consideration in cash, or by causing Terayon to issue to the Seller an
additional number of shares of Common Stock registered under the Securities Act
without being subject to lock up provisions (such registration being
substantially identical with the registration provisions provided for with
regard to the shares included in the Purchase Consideration and in the
Additional Shares) with the form of such payment, being solely at the
Purchaser's discretion. If any part of the payment is made in shares, the number
of additional shares issued shall be calculated by dividing the Additional

                                      4.
<PAGE>

Consideration by the Measurement Date Share Price. In the event that such
payment is made in shares and the Measurement Date Share Price is greater than
the closing price of the shares of Common Stock of Terayon on the date on which
the Additional Consideration is delivered to the Seller in the manner described
above, then the Purchaser shall pay to the Seller in cash, within 15 days
following the Measurement Date , an additional amount which shall be equal to:
(i) the aggregate number of  Registrable Shares held by the Seller or any of its
designees (including those held in the Escrow Fund) on the Measurement Date
multiplied by (ii) the difference between the Measurement Date Share Price and
the closing price of the shares of Common Stock of Terayon on the date on which
the Additional Consideration is delivered in shares.

     2.4  Allocation. Prior to the Closing, the parties shall mutually negotiate
and agree on, in good faith, a statement setting forth the determination of the
manner in which the Purchase Consideration is to be allocated among the
Purchased Assets. The allocation prescribed by such statement shall be
conclusive and binding upon the parties for all purposes, and the Seller, the
Purchaser or Terayon shall not file any Return or other document with, or make
any statement or declaration to, any governmental body that is inconsistent with
such allocation.

     2.5  Transaction Costs. In addition to the Purchase Consideration, the
Purchaser shall bear and pay all fees, costs and expenses incurred by the
Company in connection with the transactions contemplated by this Agreement, in
the aggregate amount of $1,397,750, which shall be allocated as follows: Mr.
Stewart Rauner's fee in the amount of $1,110,000, legal expenses to McDermott,
Will & Emery in the amount of $200,000 and legal expenses of Ravillan,
Volovelsky, Dinstein, Sneh & Co., in the amount of $75,000 plus VAT . The
payment of the above fees, costs and expenses (except for the $200,000
representing legal expenses to McDermott, Will & Emery, which shall be paid in
cash) shall be in cash or, at the Purchaser's option, by way of delivery by the
Purchaser and Terayon to the Seller, or its designee(s), of a number of
additional shares of Common Stock of Terayon having an aggregate value equal to
such fees, costs and expenses (the "Additional Shares"). The number of the
Additional Shares shall be determined in the same manner as set forth in Section
2.2 above with respect to the Acquisition Shares.

     2.6  Deliveries.  At the Closing, Seller shall deliver to Purchaser such
assignments and other good and sufficient instruments of transfer as shall be
satisfactory in form and substance to Purchaser, and shall be effective to vest
in Purchaser good and marketable title, free and clear of any liens and
encumbrances or rights and claims of others, other than the Permitted Lien, to
all of the Purchased Assets, except as otherwise provided in Section 1.3. Except
as provided in this Agreement, the Company shall pay all sales, capital,
franchise income, use, transfer or other taxes, payable by the Seller by reason
of the sale hereunder. In addition to the Purchase Consideration, an amount
equal to 17% of the value of the Purchase Consideration shall be deposited by
the Purchaser  with Naschitz, Brandes & Co. in escrow at the Closing, and shall
be available to satisfy the Seller's obligation to pay Value Added Tax in
respect of the transaction contemplated herein. Naschitz, Brandes & Co  shall
pay the amount due to the Value Added Tax authorities within no later than two
business days following the date on which Naschitz, Brandes & Co., receives a
copy of the reporting forms that are to be filed by the Company with the Value
Added Tax authorities in connection with the transaction.

and all Intellectual Property of any kind which has been developed or, is
currently being developed, by any of the Company or the Subsidiary or any

confidentiality and value of all the Intellectual Property, which measures are
reasonable and customary in the industry in which the Company operates. Each
person employed by, or acting on behalf of, the Company who, either alone or in
concert with others, developed, invented, discovered, derived, programmed or
designed the Intellectual Property has entered into a written non-disclosure
agreement with the Company regarding ownership and treatment of the Intellectual
Property, in a form reasonably satisfactory to the Company.

          (c)     Except as set forth in Schedule 3.1.12(c) attached hereto,

Common Stock of Terayon, of which one half (1/2) shall vest at the end of the
first year following the Closing and one half (1/2) shall vest at the end of two

     Notwithstanding the foregoing, in the event that the Purchaser shall
terminate the employment of any of the employees whose names are set forth in
Schedule C attached hereto, within one year following the Closing, for any
reason other than for "Cause", then such employee shall be entitled to receive,
within 30 days following the termination of his employment, the Terayon Options

employee's options in the Company equal to the difference between such
employee's vested options as of the Closing and the shares it received on the
Closing. For these purposes, "Cause" shall mean circumstances, under which the
employee would not be entitled to severance pay under Israel's Severance Pay Law
[5723 - 1963] or the refusal to carry out the instructions of the Purchaser's

with the Business of the Company. For avoidance of doubt, the fulfillment of
Seller's obligations arising out of the agreements described in Section 2.8
hereof, shall not be considered as competition with the Business of the Company.

          (b) Seller acknowledges that the restrictions on its activities under

constitute a material inducement to Purchaser's entering into and performing
this Agreement. Seller shall procure the execution of a non-compete and non-
solicitation agreement by Mr. Dmitry Goroshevsky, in the form attached hereto as
Schedule L. Seller further acknowledges, stipulates and agrees that a breach of
any such obligations and agreements will result in irreparable harm and
continuing damage to Purchaser for which there will be no adequate remedy at law
and further agrees that in the event of any breach of said obligations and
agreements, Purchaser shall be entitled to injunctive relief and to such other
relief as is proper under the circumstances.

exceeds two hundred thousand US dollars ($200,000), and where such damages

thousand US dollars ($200,000)), subject to the provisions of Section 9.5(a).

          (c) Notwithstanding anything to the contrary contained in this

<PAGE>

Seller agrees or disagrees with the Notice. In the event that the Seller agrees

subject matter of this Agreement and the other agreements, documents and
certificates specifically contemplated by this Agreement shall be pursuant to
the indemnification provisions set forth in this Section 9 and specific
performance as contemplated by Section 10.5 below.

     9.9  Prospectus Indemnification.  Notwithstanding anything to the contrary
in this Agreement, in the event any shares of Common Stock are included in a
registration statement of Terayon:

          (a) To the extent permitted by law, Terayon and/or Purchaser will
indemnify and hold harmless the Seller, the, officers, directors and legal
counsel of Seller, any underwriter (as defined in the Securities Act) for the
Seller and each person, if any, who controls the Seller or underwriter within
the meaning of the Securities Act or the Exchange Act, against any losses,
claims, damages, or liabilities (joint or several) to which they may become
subject under the Securities Act, the Exchange Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation") by Terayon: (i) any untrue
statement or alleged untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, (ii) the omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by Terayon of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
the Exchange Act or any state securities law in connection with the offering
covered by such registration statement; and Terayon will reimburse such Seller,
officer or director, underwriter or controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided however,
that the indemnity agreement contained in this Section 9.9(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of Terayon, which consent
shall not be unreasonably withheld, nor shall Terayon be liable in any

                                      30.
<PAGE>

such case for any such loss, claim, damage, liability or action to the extent
that it arises out of or is based upon a Violation which occurs in reliance upon
or in conformity with written information furnished expressly for use in
connection with such registration by such Seller, partner, officer, director,
underwriter or controlling person of the Seller.

          (b) To the extent permitted by law, the Seller will, if Common Stock
held by the Seller are included in the securities as to which such registration
qualifications or compliance is being effected, indemnify and hold harmless
Terayon, each of its directors, its officers, and legal counsel and each person,
if any, who controls Terayon within the meaning of the Securities Act and any
underwriter selling securities under such registration statement, against any
losses, claims, damages or liabilities (joint or several) to which Terayon or
any such director, officer, controlling person, or underwriter may become
subject under the Securities Act, the Exchange Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereto) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
or in conformity with written information furnished by the Seller specifically
for use in connection with such registration; and such Seller will reimburse any
legal or other expenses reasonably incurred by Terayon or any such director,
officer, controlling person or underwriter in connection with investigating or
defending any such loss, claim, damage, liability or action if it is finally
judicially determined that there was such a Violation; provided, however, that
the indemnity agreement contained in this Section 9.9(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Seller, which consent
shall not be unreasonably withheld.

          (c) Promptly after receipt by an indemnified party under this Section
9.9 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 9.9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with reasonable fees and expenses to
be paid by the indemnifying party, if representation of such indemnified party
by the counsel retained by the indemnifying party would be inappropriate due to
actual or potential differing interests between such indemnified party and any
other party represented by such counsel in such proceeding.  The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 9.9, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 9.7.

          (d) If the indemnification provided for in this Section 9.9 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying

                                      31.
<PAGE>

such indemnified party thereunder, shall to the extent permitted by applicable
law contribute to the amount paid or payable by such indemnified party as a
result of such loss, claim, damage or liability in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one
hand and of the indemnified party on the other in connection with the
Violation(s) that resulted in such loss, claim, damage or liability, as well as
any other relevant equitable considerations. The relative fault of the
indemnifying party and of the indemnified party shall be determined by a court
of law by reference to, among other things, whether the untrue statement of a
material fact or the omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

           (e) The obligations of Terayon and the Seller under this Section 9.9
shall survive completion of any offering of Common Stock in a registration
statement and the termination of this Agreement. No indemnifying party, in the
defense of any such claim or litigation, shall, except with the consent of each
indemnified party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such indemnified party of a release from all liability
in respect to such claim or litigation.

Assets (the "Closing") and the assumption of the Assumed Liabilities shall take
place at the offices of Cooley Godward llp, One Maritime Plaza, 20th Floor, San
Francisco, California 94111 at 10:00 a.m. within five (5) business days after
which the last condition set forth in Sections 8.1 and 8.2 has been fulfilled or
waived, or such other time, date and place as may be mutually agreeable to the
parties hereto (the "Closing Date"). The parties hereto agree that the Closing
may be effected by facsimile.

     2.2  Purchase Price. At the Closing, as consideration for the sale of the
Purchased Assets to Purchaser:

               (a)  Purchaser shall issue to Seller the Acquisition Shares (the
"Purchase Price"). The "Acquisition Shares" shall mean the number of shares of
Common Stock of Purchaser equal to $85,000,000 in value, calculated based on the
Weighted Average Terayon Stock Price on the business day prior to the Closing
Date .

               (b)  Purchaser shall assume the Assumed Liabilities by delivering
to Seller an Assignment and Assumption Agreement in substantially the form of
Exhibit B (the "Assumption Agreement").

     2.3  Additional Consideration. In the event the Acquisition Shares have a
value of less than $85,000,000 on the date that the Registration Statement (as
defined in Section 7.4 below) is declared effective by the SEC (the "Effective
Date"), then within five (5) business days of such date, Purchaser shall deliver

determined solely by Purchaser. The "Additional Consideration" shall be the
difference between $85,000,000 and the value of the Acquisition Consideration on
the Effective Date. The value of the Acquisition Consideration on the Effective
Date shall be calculated based on the Weighted Average Terayon Stock Price on
the Effective Date. If Purchaser shall elect to issue shares of the Common Stock
of Purchaser as payment of the Additional Consideration, then Purchaser shall
issue the number of shares equal to the value of the Additional Consideration
calculated based on the Weighted Average Terayon Stock Price on the Effective
Date.

     2.4  Allocation.

               (a)  Within 60 days after the Closing Date, Purchaser will

after receipt of such Asset Allocation Statement, Seller will propose to
Purchaser any changes to such Asset Allocation Statement. In the event Seller
does not propose any changes in writing to Purchaser within such 15-day period,
Seller will be deemed to have agreed to, and accepted, the Asset Allocation
Statement. Purchaser and Seller

                                       4.

               (b)  The Purchase Price (together with any assumed liabilities)
will be allocated in accordance with the Asset Allocation Statement as agreed to
pursuant to Section 2.4(a) hereof, and, unless otherwise required by a final

investigation and review conducted by Purchaser and its Representatives with
respect to the Business (and the furnishing of information to Purchaser and its
Representatives in connection with such investigation and review), (b) the
negotiation, preparation and review of this Agreement (including the Disclosure
Schedule attached hereto) and all agreements, certificates, opinions and other

transactions contemplated by this Agreement.

     2.6  Determination of Inventory, Equipment, Accounts Receivable and
Accounts Payable.

          2.6.1  The quantity and valuation of the Inventory and the Equipment
as of the Closing Date shall be determined from the books and records of the
Business. A physical inventory shall be taken on the Closing Date, and the books
and records of Seller shall be adjusted for Inventory and Equipment quantities
as of the Closing Date and such Inventory and/or Equipment shall be valued in
accordance with Section 2.6.2. Such physical inventory shall be conducted by
Seller's representatives at Seller's expense jointly with Purchaser's
representatives at Purchaser's expense. Any disagreement regarding the quantity
and/or value of the Inventory or the Equipment shall be resolved in the manner
and at the time described in Section 2.7.1 hereof.

          2.6.2  The Inventory, Equipment, Accounts Receivable and Accounts
Payable (as defined in Section 2.7.1 herein) reflected on the Contract Working
Capital Statement (as defined in Section 2.7.1 herein) and the Final Working
Capital Statement (as defined in Section 2.7.1 herein) shall be determined in
accordance with United States generally accepted accounting principles
consistently applied ("GAAP").

     2.7  Post-Closing Adjustment.

          2.7.1  The Acquisition Consideration will be adjusted dollar for
dollar following the Closing to the extent that the Working Capital (as
hereinafter defined) of the Business as of

                                       5.
<PAGE>

the Closing Date (the "Final Working Capital") shown upon the Final Working
Capital Statement (as hereinafter defined) differs from the Working Capital of
the Business at December 25, 1999 (the "Contract Working Capital"), as shown
upon the statement set forth in Schedule 2.7.1 attached hereto (the "Contract
Working Capital Statement"). For purposes of this Agreement, the term "Working
Capital" shall mean the difference between (a) the sum of Inventory, Equipment
and Accounts Receivable of the Business minus (b) the accounts payable of the
Business determined by reference to Section 3.1(b) below (the "Accounts
Payable"). The Final Working Capital Statement will be prepared by Purchaser
from the books of account of the Business as of the Closing Date. The Final
Working Capital Statement shall be prepared in accordance with GAAP. Purchaser
will deliver a statement showing the Final Working Capital (the "Final Working
Capital Statement") to Seller not later than 60 days after the Closing Date.
Purchaser will give representatives of Seller access to the premises of the
Business, to its books and records and to the appropriate personnel of Purchaser
for purposes of confirming the Final Working Capital Statement. Unless Seller
notifies Purchaser in writing that it disagrees with the Final Working Capital
Statement within 30 days after receipt thereof, the Final Working Capital
Statement shall be conclusive and binding on Purchaser and Seller. Any such
notice of disagreement shall specify those items or amounts included in the
Final Working Capital Statement as to which Seller disagrees. If Seller notifies
Purchaser in writing of its disagreement with the Final Working Capital
Statement within such 30-day period, then Purchaser and Seller shall attempt to
resolve their differences with respect thereto within 30 days after Purchaser's
receipt of Seller's written notice of disagreement. Any dispute regarding the
Final Working Capital Statement not resolved by Purchaser and Seller within such
30-day period will be resolved by an accounting firm mutually acceptable to both
parties or, in the absence of agreement, by an accounting firm of national
reputation selected by lot after eliminating Seller's and Purchaser's principal
outside accountants and one additional firm designated as objectionable by each
of Seller and Purchaser. The determination by the accounting firm so selected of
the Final Working Capital Statement and the Final Working Capital (with such
modifications therein, if any, as reflect such determination) shall be
conclusive and binding upon the parties. The fees and expenses of such
accounting firm in acting under this Section 2.7.1 shall be shared equally by
Purchaser and Seller.


          2.7.2  If the Contract Working Capital is greater than the Final
Working Capital, then Purchaser shall be entitled to receive from Seller, at
Seller's option, cash or the number of shares of Common Stock of Purchaser equal
in value to the difference between the Contract Working Capital and the Final
Working Capital, calculated based on the Weighted Average Terayon Stock Price on
the Closing Date. If the Final Working Capital is greater than the Contract
Working Capital, then Seller shall be entitled to receive from Purchaser, at
Purchaser's option, cash or the number of shares of Common Stock of Purchaser
equal in value to the difference between the Final Working Capital and the
Contract Working Capital, calculated based on the Weighted Average Terayon Stock
Price on the Closing Date. Notwithstanding the foregoing, in the event that the
difference between the Final Working Capital and the Contract Working Capital is
less than One Hundred Thousand Dollars ($100,000), then the party obligated to
pay such amount shall make payment in cash rather than in shares of Common Stock
of Purchaser.

     2.8  Deliveries. At the Closing, Seller shall deliver to Purchaser such
assignments and other good and sufficient instruments of transfer as shall be
satisfactory in form and substance

                                       6.
<PAGE>

to Purchaser, and shall be effective to vest in Purchaser good and marketable
title, free and clear of any liens and encumbrances or rights and claims of
others, to all of the Purchased Assets, and Purchaser shall deliver to Seller
such instruments of assumption as shall be satisfactory in form and substance to
Seller to ensure that Purchaser has assumed all of the Assumed Liabilities.

     2.9  Further Assurances . Each party agrees, at any time and from time to
time after the Closing Date, upon reasonable request from the other party, to
do, execute, acknowledge and deliver, as appropriate, such further acts, deeds,
assignments, transfers, conveyances and powers of attorney as may reasonably be
required for the better assigning, transferring, granting, conveying, assuring
and confirming to such other party, or its successors and assigns, of any of the
assets, properties or liabilities to be assigned to it or retained by such party
as provided herein.

with the SEC between August 17, 1998 and the date of this Agreement (together
with Purchaser's registration statements on Form S-8, the "Terayon SEC
Documents"). As of the time it was filed with the SEC (or, if amended or

such filing): (i) each of the Terayon SEC Documents complied in all material
respects with the applicable requirements of the Securities Act or the Exchange
Act (as the case may be); and (ii) none of the Terayon SEC Documents contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements

Terayon SEC Documents: (i) complied as to form in all material respects with the

Purchaser is a party or by which it is bound or to which any of its assets is

Act, no consent, approval, authorization order, filing, registration or
qualification of or with any court, governmental authority or third person is
required to be made or obtained by Purchaser in

other similar right.

          5.1.9     No Undisclosed Material Liabilities. There are no

clauses "(a)" through "(k)" above if Purchaser gives its prior written consent
to the taking of such action by Seller, which consent will not be unreasonably
withheld (it being understood that Purchaser's withholding of consent to any

taking of such action would not be in the best interests of the Business) or if
such action is taken at the written request of Purchaser.

     6.2  No Shop. During the Pre-Closing Period, Seller and its legal and
financial advisors will negotiate exclusively with Purchaser with respect to the

     6.4  Termination of Employees. Seller will terminate each Business Employee
immediately prior to the Closing in conjunction with Purchaser's offer of
employment to each such Business Employee. For a period of one year following
the Closing Date, Purchaser shall provide to each Business Employee who becomes
an employee of Purchaser as of the Closing Date and whose employment is
terminated due to a reduction in force ("RIF") (as defined by Seller's RIF plan
in effect as of the date of such RIF), severance and termination benefits that
are at least equivalent to the severance and termination benefits provided by
Seller under Seller's plans and practices in effect as of the date of the
Business Employee's termination due to the RIF. To the extent that such
severance benefits are greater than the severance benefits otherwise offered by
Purchaser to its other employees at the time of such RIF, Seller shall reimburse
Purchaser for the additional expense of such severance benefits. For purposes of
providing such severance and termination benefits, the Business Employees will
receive credit for their respective years of service with Seller.

     6.5  Estoppel Certificate. Seller shall use commercially reasonable efforts
to obtain an estoppel certificate, dated as of a date not more than five days
prior to the Closing Date and satisfactory in form and content to Purchaser,
executed by the landlord of 1455 Adams Court, Menlo Park, California 94025;
provided that no estoppel certificate shall be required if Seller has terminated
its lease agreement with such landlord;

     6.6  Records and Information.

          6.6.1  Purchaser agrees that all documents delivered to Purchaser by
Seller pursuant to this Agreement and all documents of the Business (including,
but not limited to, files, books and records) shall after the Closing be open
for inspection by representatives of Seller at any time during regular business
hours for reasonable and necessary purposes until such time as documents are
destroyed or possession thereof is given to the other party as provided for in
Section 6.6.2 herein and that Seller may during such period at its expense make
such copies thereof as it may reasonably request. Seller agrees that all
documents that are retained by Seller after the Closing Date and that are
related to the Business (other than tax records of Seller) shall be open for
inspection by representatives of Purchaser at any time during regular business
hours until such time as documents are destroyed or possession thereof is given
up to the other party as provided for in Section 6.6.2 herein and that Purchaser
may during such period at its expense make such copies thereof as it may
reasonably request.


          6.6.2  Without limiting the generality of Section 6.6.1, for a period
ending on the sixth anniversary of the Closing Date, neither Purchaser nor
Seller shall destroy or give up possession of any item referred to in Section
6.6.1 hereof without first offering to the other, the opportunity, at such
other's expense (but without any other payment), to obtain the same. Thereafter
each party shall be free to dispose of such items as it deems fit.

          6.6.3  Purchaser shall use reasonable efforts to afford Seller access
to Employees who were previously employees of Seller, and remain in the employ
of Purchaser or its affiliates, as Seller shall reasonably request for its
proper corporate purposes, including, without limitation, the defense of legal
proceedings. Such access may include interviews or attendance at depositions or
legal proceedings. All out-of-pocket expenses reasonably incurred by Purchaser
in connection with this Section 6.6.3 shall be paid or promptly reimbursed by
Seller.

          6.7.2  Cooperation and Exchange of Information . Purchaser shall
provide Seller with such cooperation and information as Seller reasonably may
request with respect to the filing of any Return, amended Return or claim for
refund, the determination of a liability for Taxes, or a right to refund of
Taxes, or the conduct of any audit or other proceeding in respect of Taxes. Such
cooperation and information shall include providing copies of all relevant
Returns, together with accompanying schedules and related work papers, documents
relating to rulings or other determinations by taxing authorities, and records
concerning the ownership and tax basis of property, which Purchaser may possess
concerning the Business. Purchaser shall make its employees available to Seller
on a mutually convenient basis to provide explanation of any documents or
information provided hereunder. Notwithstanding the foregoing, Purchaser shall
not be required to prepare any documents, or determine any information not then
in its possession in response to a request under this Section 6.7.2. Seller
shall reimburse Purchaser for any reasonable out-of-pocket costs incurred by
Purchaser in providing any Return, document or other written information, and
shall reimburse Purchaser for any reasonable out-of-pocket costs (including
regular wages, salaries and traveling expenses) of making employees available,
upon receipt of reasonable documentation of such costs. Except as otherwise
provided in Section 1.2(c) hereof, Seller shall retain all Returns, schedules
and work papers and all material records or other documents relating thereto,
until the expiration of the period of time beginning on the Closing Date and

                    (a)  Seller agrees that, as part of the consideration for
the payment by Purchaser of the Purchase Price, for a period of three years
immediately following the Closing Date, neither Seller nor any of its
subsidiaries or affiliates, will, directly or indirectly, operate, perform, have
any interest in or otherwise be engaged in or concerned with a business which
develops, manufactures, prepares, sells, installs or distributes products or
performs services in competition with the Business as conducted on the Closing
Date; provided, however that nothing herein contained shall be construed to
prevent Seller or any of its subsidiaries or affiliates from acquiring or
merging with any business or Person eighty percent (80%) or more of whose
consolidated revenues for the most recently completed fiscal year prior to such
acquisition were derived from businesses that are not competitive with the
Business as conducted on the Closing Date; and provided further that Seller
shall divest itself of any business so acquired within twelve (12) months of
Seller's acquisition of such business. For these purposes, ownership of
securities of a company whose securities are publicly traded under a recognized
securities exchange not in excess of five percent (5%) of any class of such
securities shall not be considered to be competition with the Business.

                    (b)  Seller acknowledges that the restrictions on its
activities under Section 6.8(a) are necessary for the reasonable protection of
Purchaser and constitute a material inducement to Purchaser's entering into and
performing this Agreement. Seller further acknowledges, stipulates and agrees
that a breach of any such obligations and agreements will result in irreparable
harm and continuing damage to Purchaser for which there will be no adequate
remedy at law and further agrees that in the event of any breach of said
obligations and agreements, Purchaser shall be entitled to injunctive relief and
to such other relief as is proper under the circumstances.

     6.9  License Grant. Seller hereby grants to Purchaser a non-exclusive,
royalty free, worldwide right and license to use the mark "Raychem" on or in
connection with the sale of products of the Business, during the period
beginning on the Closing and ending on the first anniversary of the Closing.

the standards and quality established by Seller prior to the sale of the
Business to Purchaser. Seller shall have the right, upon request of Purchaser at
least two business days in advance, to inspect during normal business hours such
products of Purchaser to determine that they are of proper quality.

be, of any event, condition, fact or circumstance that occurred or existed on or
prior to the date of this Agreement and that caused or constitutes a material
inaccuracy in or breach of any representation or warranty made by such party in
this Agreement;

                    (ii)   the discovery by Seller or Purchaser, as the case may
be, of any event, condition, fact or circumstance that occurs, arises or exists
after the date of this Agreement and that would cause or constitute a material
inaccuracy in or breach of any representation or warranty made by such party in
this Agreement if (A) such representation or warranty had been made as of the
time of the occurrence, existence or discovery of such event, condition, fact or
circumstance, or (B) such event, condition, fact or circumstance had occurred,
arisen or existed on or prior to the date of this Agreement;

                    (iii)  any breach of any covenant or obligation of Seller or
Purchaser, as the case may be; and

                    (iv)   the discovery by Seller or Purchaser, as the case may
be, of any event, condition, fact or circumstance that would make the timely
satisfaction of any of the conditions set forth in Section 8.1 or 8.2 impossible
or unlikely.

                    (b)  If any event, condition, fact or circumstance that is
required to be disclosed by Seller pursuant to Section 7.2(a) requires any
change in the Disclosure Schedule attached hereto, or if any such event,
condition, fact or circumstance would require such a change assuming the
Disclosure Schedule were dated as of the date of the occurrence, existence or
discovery of such event, condition, fact or circumstance, then Seller shall
promptly deliver to Purchaser an update to the Disclosure Schedule specifying
such change. If any event, condition, fact or circumstance is required to be
disclosed by Purchaser pursuant to Section 6.2(a), then Purchaser shall promptly
deliver to Seller written disclosure of such event, condition, fact or
circumstance. No such update by Seller or disclosure by Purchaser shall be
deemed to supplement or amend the Disclosure Schedule in the case of Seller, or
Section 5 of this Agreement, in the case of Purchaser, for the purpose of (i)
determining the accuracy of any of the representations and warranties made by
Seller or Purchaser, as the case may be, in this Agreement, or (ii) determining
whether any of the conditions set forth in Section 8.1 or 8.2 has been
satisfied.

by Seller.

                                Indemnification

Article 10, Seller agrees to indemnify, defend and hold Purchaser and each of
Purchaser's stockholders, affiliates, officers, directors, employees, agents,
successors and assigns (Purchaser and such persons are collectively hereinafter
referred to as "Purchaser's Indemnified Persons"), harmless from and against any
and all loss, liability, damage or deficiency (including interest, penalties,

inaccuracy of any representation of Seller in this Agreement; (b) the breach of
any warranty of Seller in this Agreement; (c) the non-fulfillment of any

Article 10, Purchaser agrees to indemnify, defend and hold Seller and Seller's
affiliates, officers, directors, employees, agents, successors and assigns
(Seller and such persons are hereinafter collectively referred to as "Seller's

Seller's Indemnified Persons may suffer, sustain, incur or become subject to
arising out of or due to: (a) any inaccuracy of any representation of Purchaser

or are based on any untrue statement or omission of any statement from written
information furnished to the Company by Seller or its agents, underwriter or
persons who control Seller and stated to be specifically for use in connection
with the Registration Statement.

     10.3  Survival of Representations and Warranties; Threshold and Payment for
Losses . Except as provided herein, the covenants in this Agreement shall
survive in accordance with their respective terms. The several representations
and warranties of the parties contained in this Agreement or in any document
delivered pursuant hereto and the parties' right to indemnity in accordance with
this Article 10 shall survive the Closing Date and shall remain in full force
and effect thereafter for a period of 12 months after the Closing Date and shall
be effective with respect to any inaccuracy therein or breach thereof, notice of
which shall have been duly given within such 12-month period in accordance with
Section 10.4 herein after which

                                      28.
<PAGE>

12-month period they shall terminate and be of no further force or effect.
Notwithstanding the foregoing, (i) Purchaser may give notice of, and make a
claim relating to, and shall be indemnified in connection with: (a) the breach
of the representations and warranties contained in Section 4.1.9 hereof at any
time prior to the expiration of the appropriate statute of limitations and any
extensions thereof and (b) any breach of the representations and warranties
contained in Sections 4.1.12 and 4.1.13 hereof at any time; and (ii) Seller may
give notice of, and make a claim relating to, and shall be indemnified in
connection with: (a) any rights to indemnification pursuant to Section 10.2(g)
above at any time prior to the expiration of the appropriate statute of
limitations and any extensions thereof relating to claims under the Securities
Act and (b) any breach of the representations and warranties contained in the
last sentence of Section 5.1.8 hereof at any time. Anything to the contrary
contained herein notwithstanding, neither party shall be entitled to any
recovery from the other party with respect to any inaccuracy or breach of such
warranties or representations unless and until the amount of such Loss suffered,
sustained or incurred by the asserting party, or to which such party becomes
subject, by reason of such inaccuracy or breach, shall exceed $250,000 in the
aggregate (the "Threshold Loss"), at which time the asserting party shall be
entitled to indemnification for all Losses, including any amounts in respect of
the Threshold Loss. Indemnification for Purchaser's Losses shall be paid, at
Seller's option, in cash or by Seller's return of shares of the Common Stock of
Purchaser. Indemnification for Seller's Losses, shall be paid, at Purchaser's
option, in cash or shares of the Common Stock of Purchaser. In the event any
payment hereunder is made with shares of the Common Stock of Purchaser, the
value of such shares shall be equal to the Weighted Average Terayon Stock Price
on the day preceding the date on which such payment is made.

     10.4  Notice and Opportunity to Defend. If there occurs an event which
either party asserts is an indemnifiable event pursuant to Sections 10.1 or 10.2
hereof, the party seeking indemnification (the "Indemnitee") shall notify the
party obligated to provide indemnification (the "Indemnitor") promptly. If such
event involves (a) any claim, or (b) the commencement of any action or
proceeding by a third person, the Indemnitee will give the Indemnitor written
notice of such claim or the commencement of such action or proceeding. Delay or
failure to so notify the Indemnitor shall only relieve the Indemnitor of its
obligations to the extent, if at all, that it is prejudiced by reasons of such
delay or failure. The Indemnitor shall have a period of 30 days within which to
respond thereto. If the Indemnitor accepts responsibility or does not respond
within such 30-day period, the Indemnitor shall be obligated to compromise or
defend, at its own expense and by counsel chosen by the Indemnitor and
reasonably satisfactory to the Indemnitee, such matter, and the Indemnitor shall
provide the Indemnitee with such assurances as may be reasonably required by the
Indemnitee to assure that the Indemnitor will assume and be responsible for the
entire liability at issue. If the Indemnitor does respond within such 30-day
period and rejects responsibility for such matter in whole or in part, the
Indemnitee shall be free to pursue, without prejudice to any of its rights
hereunder, such remedies as may be available to the Indemnitee under applicable
law. The Indemnitee agrees to cooperate fully with the Indemnitor and its
counsel in the defense against any such asserted liability. In any event, the
Indemnitee shall have the right to participate at its own expense in the defense
of such asserted liability. Any compromise of such asserted liability by the
Indemnitor shall require the prior written consent of the Indemnitee and until
such consent is obtained the Indemnitor shall continue the defense of such
asserted liability. If, however, the Indemnitee refuses its consent to a bona
fide offer of settlement which the Indemnitor wishes to accept, the Indemnitee
may continue to pursue such matter, free of any participation by the Indemnitor,
at the sole expense of

                                      29.
<PAGE>

the Indemnitee. In such event, the obligation of the Indemnitor to the
Indemnitee shall be equal to the lesser of (i) the amount of the offer of
settlement which the Indemnitee refused to accept plus the costs and expenses of
the Indemnitee prior to the date the Indemnitor notifies the Indemnitee of the
offer of settlement, and (ii) the actual out-of-pocket amount the Indemnitee is
obligated to pay as a result of the Indemnitee's continuing to pursue such
matter. The Indemnitor shall be entitled to recover from the Indemnitee any
additional expenses incurred by the Indemnitor as a result of the decision of
the Indemnitee to pursue such matter.

     10.5  Reduction for Insurance. The amount which the Indemnitor is required
to pay to, for, or on behalf of the Indemnitee pursuant to this Article 10 shall
be reduced (including, without limitation, retroactively) by any insurance
proceeds actually recovered by or on behalf of the Indemnitee in reduction of
the related indemnifiable loss (the "Indemnifiable Loss"). Amounts required to
be paid, as so reduced, are hereinafter sometimes called an "Indemnity Payment".
If the Indemnitee shall have received, or if the Indemnitor shall have paid on
its behalf, an Indemnity Payment in respect of an Indemnifiable Loss and shall
subsequently receive, directly or indirectly, insurance proceeds (which
duplicate in whole or in part, the Indemnity Payment) in respect of such
Indemnifiable Loss, then the Indemnitee shall promptly pay to the Indemnitor the
amount of such insurance proceeds, or, if less, the amount of the Indemnity
Payment. The parties hereto agree that the foregoing shall not affect the
subrogation rights of any insurance companies making payments hereunder.

     10.6  Defense of Third-Party Claims. In the event of the assertion or
commencement by any Person of any claim or Legal Proceeding (whether against
Purchaser or against any other Person) with respect to which any of Purchaser's
Indemnified Persons shall have the right to seek indemnification pursuant to
this Section 10, Purchaser shall have the right, at its election, to proceed
with the defense of such claim or Legal Proceeding on its own. If Purchaser so
proceeds with the defense of any such claim or Legal Proceeding:

          (a)  Seller shall indemnify Purchaser against all reasonable expenses
relating to the defense of such claim or Legal Proceeding;

          (b)  Purchaser shall have the right to settle, adjust or compromise
such claim or Legal Proceeding with the consent of Seller; provided, however,
that such consent shall not be unreasonably withheld.

Purchaser shall give Seller prompt notice of the commencement of any such Legal
Proceeding against Purchaser; provided, however, that any failure on the part of
Purchaser to so notify Seller shall not limit any of the rights of Purchaser's
Indemnified Persons under this Section 10 (except to the extent such failure
materially prejudices the defense of such Legal Proceeding).

                                  ARTICLE 11

                                 Miscellaneous

     11.1  Attorneys' Fees. If any action or proceeding relating to this

                            SHARE PURCHASE AGREEMENT

     This Share Purchase Agreement (this "Agreement") is made and entered into
as of March 26, 2000, by and among: Terayon Communication Systems, Inc., a
Delaware corporation ("Terayon"); Ultracom Communications Holdings (1995) Ltd.,
a company organized under the laws of the State of Israel (the "Company"); and
the persons whose names are set forth on the signature page attached hereto
(each, individually, a "Seller" and, collectively, the "Sellers" or the
"Shareholders"). Certain other capitalized terms used in this Agreement are
defined in Exhibit A.

                                    Recitals

     A.   The Company is engaged principally in the development of chips for
data communications over the TV cable infrastructure for Custom Premises
Equipment, and its principal place of business is at 11 Harugey Hamalchut
Street, Tel Aviv, Israel.

     B.   The Sellers, collectively, own all the issued and outstanding shares
of the Company (the "Shares").

     C.   Terayon desires to acquire all of the Sellers' Shares and the Sellers
desire to sell such Shares to Terayon.

     D.   The Sellers and Terayon desire to make certain representations and
warranties and other agreements in connection with the transactions contemplated
hereby.

     E.   For accounting purposes, it is intended that the transaction
contemplated by this Agreement be treated as a "purchase."

     F.   This Agreement has been approved by the respective boards of directors
of Terayon and the Company.

                                   Agreement

     The parties to this Agreement agree as follows:

Section 1.  Description of Transaction.

     1.1    Purchase and Sale.  Subject to the terms and conditions of this
Agreement, on the Closing Date (as defined below), the Sellers shall sell,
transfer, assign, convey and deliver to Terayon, and Terayon shall purchase from
the Sellers all such Sellers' Shares, in each case, free and clear of all Liens.
The closing of the purchase and sale (the "Closing") shall take place at the
offices of Naschitz Brandes & Co., 5 Tuval Street, Tel Aviv, Israel at 10:00
a.m., on March [15], 2000 or on such later date (which is no later than 40
business days after the date hereof) on which all the conditions set forth in
Sections 6 and 7 have been satisfied or waived, or on such other date, time and
place as the parties may mutually agree
<PAGE>

(the "Closing Date"). At the Closing, the Sellers shall cause the Company to
deliver to Terayon one or more instruments representing the Sellers' Shares, and
Terayon shall (i) issue the Share Consideration (as defined below) to the
Sellers' Representative for distribution to the Sellers in accordance with the
column in Schedule A captioned "Share Consideration", (ii) pay the cash payment
to the Sellers' representative for distribution to the Sellers in accordance
with the column in Schedule A captioned "Cash Payment", and (iii) deposit the
Escrow Shares (as defined below) with the Escrow Agent, which amounts together
represent the aggregate portion of the Purchase Consideration (as defined below)
payable to the Sellers hereunder.

     1.2   Further Assurances. If, at any time after the Closing Date, Terayon
shall consider or be advised that any deeds, bills of sale, assignments or
assurances or any other acts or things are reasonably necessary, desirable or
proper (a) to vest, perfect or confirm, of record or otherwise, in Terayon, its
right to, and title or interest in, the Sellers' Shares or (b) otherwise to
carry out the purposes of this Agreement, Terayon shall so advise the Sellers'
Representative in writing, and the Sellers thereupon shall execute and deliver
all such deeds, bills of sale, assignments and assurances and do all such other
acts and things reasonably necessary, desirable or proper to vest, perfect or
confirm its right, title or interest in, to or under the Sellers' Shares, and
otherwise to carry out the purposes of this Agreement.

     1.3   Purchase Consideration.  The consideration for the Sellers' Shares
and Vested Options (the "Purchase Consideration"), shall be as follows: Terayon
shall deliver to the Sellers' Representative for distribution to the Sellers,
the number of shares of Common Stock of Terayon (the "Terayon Shares" or the
"Share Consideration") having a value of (i) US$30,000,000 plus (ii)
US$2,270,000, which represents the Company's Net Cash as of March 1, 2000, plus
(iii) the aggregate exercise price which will have been paid upon exercise of
the Vested Options. Such number of Terayon Shares shall be calculated using the
closing price of Terayon Common Stock at the fifth business day prior to the
Closing. The Share Consideration may be increased pursuant to Section 5.6 below.
Of the Share Consideration, shares of Common Stock of Terayon with a value equal
to three million US dollars ($3,000,000) shall be deposited with the Escrow
Agent to be held in the Escrow Fund and shall be available to satisfy the
indemnification obligations as provided in Section 9 (the "Escrow Shares"). As
set forth in Section 1.4 below, Terayon shall be entitled to pay the Sellers
cash in an amount of up to two hundred and fifty thousand US Dollars ($250,000)
(the "Cash Payment") in lieu of such equal portion of the Share Consideration
set forth above. The Share Consideration (which includes the shares to be
delivered to the Sellers, the Escrow Shares and the shares to be delivered to
all holders of Vested Options as specified in Section 1.6 below) and the Cash
Payment shall constitute, collectively, the Purchase Consideration.

     1.4   Method of Share Transfer.  The Transfer of the Terayon Shares as set
forth in Section 1.3 above shall be made by Terayon to the Sellers'
Representative on the Closing Date. The Cash Payment made by Terayon to the
Sellers' Representative on the Closing Date shall be made by wire transfer of
immediately available funds to the account specified by the Sellers'
Representative in writing to Terayon at least two (2) business days prior to the
Closing Date (the "Account"). The Cash Payment shall reduce the Share
Consideration by such number of Terayon Shares, the value of which (calculated
in the manner set forth in Section 1.3 above with respect to the Share
Consideration) shall be equal to the Cash Payment.
<PAGE>

     1.5   Accounting Treatment.  For accounting purposes, the transaction
contemplated by this Agreement is intended to be treated as a "purchase."

     1.6   Employee Options.

           (a) There are currently outstanding and unexercised options to
acquire Ordinary Shares (the "Options") issued by the Company to employees,
directors and consultants listed in Schedule A (the "Option Holders"). The names
of the Option Holders and the number of Ordinary Shares covered by each Option
are set forth on Schedule A.

           (b) At Closing, all Options that are vested as of the Closing Date
(the "Vested Options"), shall be exercised or canceled , and thereafter Terayon
shall grant to each Holder of Vested Options such number of options to purchase
Common Stock of Terayon ("Terayon Options"), fully vested, indicated opposite
such Option Holder's name on Schedule A. All Such Terayon Options shall have an
exercise price equal to the par value of the underlying Common Stock ($0.01),
and shall be exercisable at any time during the five (5) year period following
the Closing Date. Prior to the Closing, no Option Holder shall exercise or
transfer any Options.

           (c) All Options that are not vested as of the Closing Date (the
"Unvested Options") shall be canceled and replaced with Terayon Options
provided, however, that the material terms (including  the vesting schedule and
the exercise price  with respect to such Terayon Options) shall be
substantially identical to the terms and conditions of the canceled and replaced
Unvested Options. If necessary, the Company shall cause any trustee holding such
Options to take appropriate action to facilitate and effect the above.
Notwithstanding the foregoing, in the event that the vesting of any Terayon
Option is accelerated upon the termination of any employment of holder of such
Terayon Option at any time prior to the first anniversary of the Closing in
accordance with the vesting schedule that would have applied to such holder's
Unvested Options, the Shares of Common Stock of Terayon underlying such Terayon
Options, less the exercise price thereof, shall be deducted from the Purchase
Consideration and Terayon shall be entitled to receive such shares from the
Escrow Shares.

           (d) As soon as practicable following the date hereof and in any event
prior to the Closing, the Company shall secure the written agreement, in form
and substance reasonably acceptable to Terayon, of each Option Holder and
Warrant Holder to the terms and conditions of this Agreement (the "Option and
Warrant Holder Consent Letter and Counterpart Signature Page"). For the
avoidance of doubt, the total number of shares of Common Stock to be issued to
the Sellers and the Option and Warrant Holders hereunder shall be equal to the
Share Consideration.

           Section 2.  Representations and Warranties of the Company.

     The Company represents and warrants, to and for the benefit of the
Indemnitees, as follows:
<PAGE>

calculating the average closing price of the shares of Common Stock of Terayon
over the fifteen (15) trading days immediately preceding the fifth business day

Shares of the Company to the Sellers' Representative (for distribution to the
Sellers), without liability to either party.

or incorporation by reference in the Registration Statement will, at the time
the Registration Statement is filed with the SEC and at the time it becomes

fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading.  If at any time
<PAGE>

prior to the date on which the Registration Statement is declared effective by
the SEC any event in respect of Terayon, its officers and directors, or any of
its subsidiaries should occur which is required to be described an amendment of,
or a supplement to, the Registration Statement, Terayon shall promptly so advise
the Sellers and such event shall be so described, and any such amendment or
supplement to the Registration Statement (which the Sellers' Representative
shall have a reasonable opportunity to review, and, to the extent such
amendments have a Material Adverse Effect on the value of the Share
Consideration, may rescind the transaction) shall be promptly filed with the
SEC. The Registration Statement will comply as to form in all material respects
with the provisions of the Securities Act and the rules and regulations
thereunder.

     9.3   Notice of Claims; Defense of Third Party Claims.

           (a) In the event of the assertion or commencement by any Person of
any claim, demand, notice or Legal Proceeding (whether against the Sellers,
against Terayon or against any other Person) with respect to which any of the
Indemnitees shall have the right to seek indemnification pursuant to this
Section 9, Terayon shall notify the Sellers' Representative and the Escrow Agent
with reasonable promptness of such action, claim or demand (the "Third Party
Claims"), specifying, to the extent known, the nature, circumstances and the
amount of such Third Party Claim (a "Third Party Claim Notice"). The Sellers'
Representative shall have thirty days from its receipt of a Third Party Claim
Notice (the "Third Party Claim Notice Period") to notify Terayon (i) whether the
Sellers' Representative disputes the Indemnitee's right of reimbursement from
the Escrow Fund with respect to such Third Party Claim, and (ii) if the Sellers'
Representative does not dispute such right of reimbursement, whether or not it
desires to defend the Indemnitee against such Third Party Claim.

           (b) If the Sellers' Representative notifies Terayon within the Third
Party Claim Notice Period that (i) the Sellers' Representative does not dispute
the Indemnitee's right of reimbursement and (ii) the Sellers' Representative
desires to defend against such Third Party Claim, then the Sellers'
Representative shall have the right to assume and control the defense of such
Third Party Claim by appropriate proceedings with counsel reasonably acceptable
to Terayon, and the Seller's Representative shall be entitled to reimbursement
first out of the Escrow Fund for such Defense. The Indemnitee may participate
in, but not control, any such defense or settlement, at its sole cost and
expense; provided, however, that the Sellers' Representative and Terayon shall
jointly control the defense of any tax audit or proceeding which could
reasonably be expected to have a Material Adverse Effect on the business or
condition of the Company for any taxable period ending on or after the Closing.

           (c) If the Sellers' Representative (i) disputes the Indemnitee's
right of reimbursement with respect to a Third Party Claim, or (ii) does not
dispute such right of reimbursement but fails to promptly assume and prosecute
the defense of such Third Party Claim, then Terayon or the Indemnitee shall be
entitled to assume and control the defense of such Third Party Claim. Unless the
Sellers' Representative has disputed the Indemnitee's right to reimbursement for
a Third Party Claim, Indemnitee shall be entitled to reimbursement first from
the Escrow Fund for such defense. If the Sellers' Representative does not assume
the defense of a Third Party Claim for any reason, it may still participate in,
but not control, the defense of such Third Party Claim at the Sellers'
Representative's sole cost and expense.

           (d) The party responsible for the defense of any Third Party Claim
(the "Responsible Party") shall, to the extent reasonably requested by the other
party, keep such other party informed as to the status of any Third Party Claim
for which such party is not the Responsible Party, including, without
limitation, all settlement negotiations and offers. With respect to a Third
Party Claim for which the Sellers' Representative is the Responsible Party,
Terayon shall, and shall cause each Indemnitee to, make available to the
Sellers' Representative and its representatives all books and records of Terayon
and the Indemnitees relating to such Third Party Claim and shall render to the
Sellers' Representative such assistance and access to records and the
representatives of Terayon and the Indemnitees as

the Sellers' Representative and its representatives may reasonably request.

           (e) In the event that an Indemnitee has a claim out of the Escrow
Fund for reimbursement which does not involve a Third Party Claim (a "Direct
Claim"), Terayon shall notify the Sellers' Representative of such Direct Claim
with reasonable promptness, specifying, to the extent known, the nature,
circumstances and amount of such Direct Claim (a "Direct Claim Notice" and
together with Third Party Claim Notices, the "Claim Notices"). If the Sellers'
Representative notifies Terayon that it disputes an Indemnitee's right of
reimbursement from the Escrow Fund with respect to a Claim set forth in a Claim
Notice, Terayon, the Indemnitee and the Sellers' Representative shall use
reasonable efforts to resolve such dispute and, in the event that such efforts
are unsuccessful, shall resolve such dispute by arbitration. The Arbitration
proceedings will be in English and will take place in Tel Aviv, Israel or such
other place, as the parties shall agree upon. The arbitrator(s) shall not be
bound by any judicial rules of evidence or procedure but shall be bound by the
substantive laws of the State of Israel. The parties will attempt to select an
arbitrator on which Terayon and the Sellers' Representative shall agree. In the
event of disagreement as to the identity of the arbitrator, each party shall
select an arbitrator and the two arbitrators shall select, by mutual agreement,
a third arbitrator.

           (f) Neither the Sellers' Representative, on the one hand, nor Terayon
or any other Indemnitee, on the other hand, shall enter into any settlement of
any Third Party Claim without the prior written consent of the other party,
which consent shall not be unreasonably withheld. The Responsible Party shall
promptly notify the other party of each settlement offer (including whether or
not the Responsible Party is willing to accept the proposed settlement offer)
with respect to a Third Party Claim. Such other party agrees to notify the
Responsible Party with reasonable promptness whether or not such party is
willing to accept the proposed settlement offer. If an Indemnitee fails to
consent to any settlement offer of a Third Party Claim (whether or not Terayon
is the Responsible Party with respect to such Third Party Claim), Terayon or the
Indemnitee may continue to contest or defend such Third Party Claim and, in such
event, the maximum reimbursement from the Escrow Fund with respect to such Third
Party Claim (including the reasonable costs and expenses of contesting or
defending such Third Party Claim incurred after the Indemnitee fails to consent
to such settlement offer) shall not exceed the amount of such settlement offer.
If the Sellers' Representative fails to consent to any settlement offer of a
Third Party Claim (whether or not the Sellers' Representative is the Responsible
Party with respect to such Third Party Claim), the Sellers' Representative may
continue to contest or defend such Third Party Claim and, in such event, subject
to the limitations on indemnification set forth in Section 9.5, the Indemnitee
may make a Claim against the Escrow Fund for the excess, if any, of the (i)
amount of Damages ultimately recovered against an Indemnitee as a result of such
Third Party Claim minus (ii) the amount of such settlement offer, and the
portion of the Damages equal to the settlement offer plus the Damages of the
Indemnitees incurred in connection with the defense of such Third Party Claim
through the date on which the Sellers' Representative rejected the settlement
offer.

     9.4   Exercise of Remedies by Indemnitees Other Than Terayon. No Indemnitee
(other than Terayon or any successor thereto or assign thereof) shall be
permitted to assert any indemnification claim or exercise any other remedy under
this Agreement unless Terayon (or any successor thereto or assign thereof) shall
have consented to the assertion of
<PAGE>

such indemnification claim or the exercise of such other remedy.

     9.5   Limitations on Indemnification.

           (a)   Except as specifically set forth herein, the maximum amount of
indemnifiable Damages that may be recovered from the Sellers arising out of or
resulting from Section 9.2(a) shall be an amount equal to the Purchase
Consideration; provided, however, that if the value of the claims made by
Terayon exceed 50% of the Share Consideration (valued in accordance with Section
1.3 above), the Sellers' Representative  may, within 21 days following his
receipt of such claim(s), notify Terayon in writing of the Sellers' intention to
terminate this Agreement and purchase the Shares of the Company back from
Terayon for restitution of the Purchase Consideration. Terayon shall, within 14
days of its receipt of such written notice, either (i) amend the claim(s) so
that the aggregate amount of such claim(s) does not exceed 50% of the Share
Consideration; or (ii) deliver the shares of the Company to the Sellers'
Representative (for distribution to the Sellers) in exchange for the Purchase
Consideration or an amount equal thereto.

           (b)  Notwithstanding anything to the contrary contained in this
Agreement, no Indemnitee shall be entitled to seek indemnification from the
Sellers under this Agreement with respect to any Damages arising out of or
resulting from Section 9.2(a), until the aggregate amount of such Damages
exceeds one hundred and fifty thousand US dollars ($150,000), and where such
damages exceed one hundred and fifty thousand US dollars ($150,000), the
Indemnitees shall be entitled to indemnification in full (with no deduction of
the one hundred and fifty thousand US dollars ($150,000)), subject to the
provisions of Section 9.5(a). This $150,000 threshhold shall not apply to (i) a
shortfall in the amount of Net Cash which the Company shall have, as of  March
1, 2000, as compared to the Net Cash as calculated pursuant to Section 1.3
hereof or (ii) the shares of Terayon which may be delivered to holders of
Unvested Options pursuant to Section 1.6(c) hereof.

           (c)  Notwithstanding anything to the contrary contained in this
Agreement, the maximum amount of indemnifiable Damages that may be recovered
from Terayon arising out of or resulting from Section 9.2(c) shall be an amount
equal to the Purchase Consideration.

           (d)  Notwithstanding anything to the contrary contained in this
Agreement, the Sellers shall not be entitled to seek indemnification from
Terayon under this Agreement with respect to any Damages arising out of or
resulting from Section 9.2(c), until the aggregate amount of such Damages
exceeds one hundred and fifty thousand US dollars ($150,000), and where such
damages exceed one hundred and fifty thousand US dollars ($150,000), the Sellers
shall be entitled to indemnification in full (with no deduction of the one
hundred and fifty thousand US dollars ($150,000)), subject to the provisions of
Section 9.5(c).

     9.6   Exclusive Remedies.  Terayon acknowledges and agrees that its sole
and exclusive remedy (except in the case of fraud, in which case Terayon
reserves all rights available to it under the law with respect to the party
committing such fraud) with respect to any and all claims relating to the
subject matter of this Agreement and the other agreements, documents and
certificates specifically contemplated by this Agreement shall be pursuant to
<PAGE>

the indemnification provisions set forth in this Section 9 and specific
performance as contemplated by Section 10.11 below.

     9.7   Prospectus Indemnification.  Notwithstanding anything to the contrary
in this Agreement, in the event any shares of Common Stock are included in a
registration statement of Terayon:

           (a) To the extent permitted by law, Terayon will indemnify and hold
harmless each of the Sellers, the officers, directors and legal counsel of each
of the Sellers, any underwriter (as defined in the Securities Act) for the
Sellers and each person, if any, who controls any of the Sellers or underwriter
within the meaning of the Securities Act or the Exchange Act, against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation") by Terayon: (i) any untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission to state therein a material
fact required to be stated therein, or necessary to make the statements therein
not misleading, or (iii) any violation or alleged violation by Terayon of the
Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state
securities law in connection with the offering covered by such registration
statement; and Terayon will reimburse such Seller, officer or director,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided however, that the indemnity
agreement contained in this Section 9.7(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of Terayon, which consent shall not
be unreasonably withheld, nor shall Terayon be liable in any such case for any
such loss, claim, damage, liability or action to the extent that it arises out
of or is based upon a Violation which occurs in reliance upon or in conformity
with written information furnished expressly for use in connection with such
registration by such Seller, partner, officer, director, underwriter or
controlling person of the Seller.

           (b) To the extent permitted by law, the Seller will, if Common Stock
held by the Seller are included in the securities as to which such registration
qualifications or compliance is being effected, indemnify and hold harmless
Terayon, each of its directors, its officers, and legal counsel and each person,
if any, who controls Terayon within the meaning of the Securities Act and any
underwriter selling securities under such registration statement, against any
losses, claims, damages or liabilities (joint or several) to which Terayon or
any such director, officer, controlling person, or underwriter may become
subject under the Securities Act, the Exchange Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereto) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
or in conformity with written information furnished by the Seller specifically
for use in connection with such registration; and each such Seller will
reimburse any legal or other expenses reasonably incurred by Terayon or any such
director, officer, controlling person or underwriter in connection with
investigating or defending any such loss, claim,
<PAGE>

damage, liability or action if it is judicial determined that there was such a
Violation; provided, however, that the indemnity agreement contained in this
Section 9.7(b) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability or action if such settlement is effected without the
consent of the Seller, which consent shall not be unreasonably withheld.

           (c) Promptly after receipt by an indemnified party under this Section
9.7 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 9.7, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own c, with the fees and expenses to be paid by the
indemnifying party, if representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or
potential differing interests between such indemnified party and any other party
represented by such counsel in such proceeding.  The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, if materially prejudicial to its ability to defend such action,
shall relieve such indemnifying party of any liability to the indemnified party
under this Section 9.7, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 9.7.

           (d) If the indemnification provided for in this Section 9.7 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any losses, claims, damages or liabilities referred to herein,
the indemnifying party, in lieu of indemnifying such indemnified party
thereunder, shall to the extent permitted by applicable law contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and of the indemnified
party on the other in connection with the Violation(s) that resulted in such
loss, claim, damage or liability, as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by a court of law by reference to, among
other things, whether the untrue statement of a material fact or the omission to
state a material fact relates to information supplied by the indemnifying party
or by the indemnified party and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.
<PAGE>

           (e) The obligations of Terayon and the Sellers under this Section 9.7
shall survive completion of any offering of Common Stock in a registration
statement and the termination of this Agreement.  No indemnifying party, in the
defense of any such claim or litigation, shall, except with the consent of each
indemnified party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such indemnified party of a release from all liability
in respect to such claim or litigation.

SECTION 10.  MISCELLANEOUS PROVISIONS.

     10.1  Sellers' Representative. JVP Properties Ltd. is hereby designated by
the Sellers as the representative of the Sellers for purposes of this Agreement
and the Escrow Agreement and as agent and attorney-in-fact of the Sellers with
respect hereto and thereto (the "Sellers' Representative"). The Sellers'
Representative shall have the authority to take such actions and exercise such
discretion on behalf of its respective principals as are required of the
Sellers' Representative pursuant to the terms of this Agreement and the Escrow
Agreement (and any such actions shall be binding on each of the Sellers
represented by such Sellers' Representative), including without limitation the
following:

           (i)  To execute, acknowledge, deliver, record and file all ancillary
agreements, waivers, consents, certificates and documents which the Sellers'
Representative deems necessary or appropriate in connection with the
consummation of the transactions contemplated by the terms and provisions of
this Agreement;

          (iii) To receive and make any payments provided for under this
Agreement and acknowledge receipt and payment thereof;

          (iv)  To waive any breach or default under the Agreement, or to waive
any condition precedent to the Closing under Section 7 hereof;

          (v)   To amend or terminate this Agreement pursuant to its terms;

          (vi)  To receive service of process in connection with any claims
under this Agreement or the Escrow Agreement; and

          (vii) To perform the obligations and exercise the rights under the
Escrow Agreement, including the settlement of any claims and disputes arising
thereunder.

     The designation and appointment of the Sellers' Representative is
irrevocable and shall not be affected by the subsequent death, incapacity,
insolvency or dissolution of any Seller. The Sellers' Representative shall be
indemnified by the Sellers for any expense and liability which it will incur in
connection with his actions as a sellers' representative (including, but not
limited to, any liability towards any or all of the Sellers resulting from
negligent actions or omissions, and erroneous resolutions taken in his capacity
as a sellers' representative under this section), and all his actions and
resolution are hereby approved by the Sellers as long as, and until he has been
replaced or removed from his role as Shareholders' representative pursuant to
the terms hereof. Terayon shall have the right to rely upon all actions taken or
omitted by the Sellers' Representative pursuant to this Agreement, all of which
actions and omissions shall be binding on each of the Sellers. If the
<PAGE>

Sellers' Representative shall be dissolved or otherwise be unable to fulfill his
responsibilities as agent of the Sellers, then the Sellers holding a majority in
interest of the capital stock of the Company (assuming the exercise of all
options and warrants and the exercise and conversion of all exercisable and
convertible securities) shall, within ten days after such circumstances, appoint
a successor agent and, promptly thereafter, shall notify Terayon of the identity
of such successor. Any such successor shall become the "Sellers' Representative"
for purposes of this Agreement. The Sellers hereby authorize the Sellers'
Representative to pay all reasonable and documented legal fees and expenses
incurred by the Company and the Sellers (as further described in Section 10.3
below) from the Purchase Consideration prior to the distribution of the Purchase
Consideration to the Sellers. The Sellers hereby agree to transfer to the
Sellers' Representative such additional cash amounts as shall be determined by
the Sellers' Representative are necessary to pay all legal fees and expenses
incurred by the Company and the Sellers (as further described in Section 10.3
below), and in connection with the performance of his duties as the Sellers'
Representative.

     10.2  Further Assurances.  Each party hereto shall execute and cause to be
delivered to each other party hereto such instruments and other documents, and
shall take such other actions, as such other party may reasonably request (prior
to, at or after the Closing) for the purpose of carrying out or evidencing any
of the transactions contemplated by this Agreement.

     10.3  Fees and Expenses. Each of the Company and Terayon shall bear and pay
all fees, costs and expenses (including legal fees, accounting fees and
brokerage fees) that have been incurred or that are incurred by such party,
including all fees, costs and expenses incurred by such party in connection with
or by virtue of (a) the investigation and review conducted by Terayon and its
Representatives with respect to the Company's business (and the furnishing of
information to Terayon and its Representatives in connection with such
investigation and review), (b) the negotiation, preparation and review of this
Agreement (including the Disclosure Schedule) and all agreements, certificates,
opinions and other instruments and documents delivered or to be delivered in
connection with the transactions contemplated by this Agreement, and (c) the
preparation and submission of any filing or notice required to be made or given
in connection with any of the transactions contemplated by this Agreement
(except with respect to stamp duty, as specified in Section 5.8 above) , and the
obtaining of any Consent required to be obtained in connection with any of such
transactions; provided however that all the Company's fees and expenses shall be
applied to reduce the Net Cash and, accordingly, the Purchase Consideration.

     10.4  Attorneys' Fees.  If any action or proceeding relating to this
Agreement or the enforcement of any provision of this Agreement is brought
against any party hereto, the prevailing party shall be entitled to recover
reasonable attorneys' fees, costs and disbursements (in addition to any other
relief to which the prevailing party may be entitled).

     10.5  Notices.  Any notice or other communication required or permitted to
be delivered to any party under this Agreement shall be in writing and shall be
deemed delivered, given and received when delivered (by hand, by registered
mail, by courier or express delivery service or by facsimile) to the address or
facsimile telephone number set forth beneath the name of such party below (or to
such other address or facsimile telephone number as such party shall have
