W I T N E S S E T H :

WHEREAS, pursuant to the Asset Purchase Agreement dated December 5, 2006 (the “Asset Purchase Agreement”), among the Company; TranSwitch (Israel) Ltd., an Israeli corporation and a wholly-owned subsidiary of the Company (“Acquisition Sub”); and the Shareholder, Acquisition Sub will purchase, in exchange for cash and shares of Common Stock of the Company, DJCE’s ASIC Design Center (the “Division”) (the “Asset Purchase”) all subject to the terms and conditions of the Asset Purchase Agreement;

WHEREAS, the Company and the Shareholder wish to set forth certain rights and obligations with regard to the registration of the Shares and if applicable the Earnout Shares;

NOW, THEREFORE, the parties hereto, intending to be legally bound, agree as follows:

1. Certain Definitions. As used in this Agreement, the following terms shall have the following respective meanings:

“Closing Date” shall have the same meaning ascribed to it in the Asset Purchase Agreement.

“Commission” shall mean the United States Securities and Exchange Commission, or any other federal agency at the time administering the Securities Act.

“Common Stock” shall mean the Common Stock, $.001 par value, of the Company, as constituted as of the date of this Agreement.

“Exchange Act” shall mean the United States Securities Exchange Act of 1934, as amended, or any similar federal statute, and the rules and regulations of the Commission thereunder, all as the same shall be in effect at the time.

“ISL” shall mean the Israel Securities Law, 5768-1968, as amended (together with the rules and regulations promulgated thereunder).

“Registration Expenses” shall mean the expenses so described in Section 7.

2. Securities Act Matters. Shareholder acknowledges and agrees that the Shares and if applicable, the Earnout Shares have not been registered under the Securities Act or under the securities laws of any state or foreign jurisdiction, in reliance upon certain exemptive provisions of such statutes. Shareholder recognizes and acknowledges that such claims of exemption are based, in part, upon each Shareholder’s representations contained in this Agreement. Shareholder further recognizes and acknowledges that, because the Shares and if applicable, the Earnout Shares are unregistered under federal and state laws, they are not presently eligible for public resale, and may only be resold in the future pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to a valid exemption from such registration requirements. Shareholder recognizes and acknowledges that Rule 144 (which facilitates routine sales of securities in accordance with the terms and conditions of that Rule, including a holding period requirement) or any other exemption promulgated under the Securities Act is not now available for resale of the Shares, and Shareholder recognizes and acknowledges that, in the absence of the availability of Rule 144, a sale pursuant to a claim of exemption from registration under the Securities Act would require compliance with some other exemption under the Securities Act, none of which may be available for resale of the Shares. Shareholder recognizes and acknowledges that, except as set forth in this Agreement, the Company is under no obligation to register the Shares and if applicable the Earnout Shares, either pursuant to the Securities Act or the securities laws of any state or jurisdiction.

3. Restrictive Legend. Each certificate representing Shares and if applicable, the Earnout Shares shall, except as otherwise provided in this Section 3, be stamped or otherwise imprinted with a legend substantially in the following form:

“The Securities represented hereby have not been registered under the Securities Act of 1933, as amended, and may not be sold, transferred or otherwise disposed of except in accordance with the terms thereof and unless registered with the Securities and Exchange Commission of the United States and the securities regulatory authorities of certain states or unless an exemption from such registration is available. The holder of this security is entitled to certain registration rights and subject to certain restrictions on sale, pledge or disposition of this security as set forth in a Registration Rights Agreement, dated as of January 11, 2006, a copy of which may be obtained from the Secretary of the Company.”

- 2 -

Such certificates shall not bear such legend if in the opinion of counsel satisfactory to the Company the securities being sold thereby may be publicly sold without registration under the Securities Act or if such securities have been sold pursuant to Rule 144, any other exemption under the Securities Act, or an effective registration statement.

- 5 -

the Shareholder and each such controlling person, promptly upon presentation of appropriate invoices, for any legal or other expenses reasonably incurred by them in connection with investigating, preparing to defend, defending or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action, provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made based upon information furnished in writing by the Shareholder or such Shareholder controlling person expressly for use in the Registration Statement or the Earnout Registration Statement.

(b) In connection with the registration of the Shares or Earnout Shares under the Securities Act pursuant to Section 4, the Shareholder will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of the Securities Act, each officer of the Company who signs such registration statement and each director of the Company, against all losses, claims, damages or liabilities, joint or several (including any amounts paid in settlement), to which the Company or such officer or director may become subject under the Securities Act, the ISL or otherwise, insofar as such losses, claims, damages or liabilities (or actions, proceedings or settlements in respect thereof) arise out of or are based upon (i) the failure of the Shareholder to comply with the provisions of Section 11 herein or (ii) any untrue statement or alleged untrue statement of any material fact contained in the registration statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and each such officer and director for any legal or other expenses reasonably incurred by them in connection with investigating, preparing to defend, or defending any such loss, claim, damage, liability or action, provided, however, that, the Shareholder will be liable hereunder in any such case if and only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon, in conformity with and based upon information pertaining to the Shareholder and furnished in writing by or for the Shareholder expressly for use in the Registration Statement or the Earnout Registration Statement, provided, further, however, that the liability of the Shareholder hereunder shall be limited to the proceeds received by the Shareholder from the sale of the Shares covered by the Registration Statement or the Earnout Shares covered by the Earnout Registration Statement; and provided, further, however, that the obligations of the Shareholder hereunder 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 Shareholder.

(c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action involving the subject matter of the foregoing indemnity provisions, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 8 and shall only relieve it from any liability which it may have to such indemnified party under this Section 8 if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement

- 6 -

thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof and the approval by the indemnified party of the counsel chosen by the indemnifying party, the indemnifying party shall not be liable to such indemnified party under this Section 8 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected, provided, however, that, if the defendants in any such action include both the indemnified party and the indemnifying party and if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred. No indemnifying party will 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, without the consent of the indemnified party.

(d) In order to provide for just and equitable contribution to joint liability in any case in which either (i) the Shareholder exercising rights under this Agreement makes a claim for indemnification pursuant to this Section 8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 8 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of the Shareholder in circumstances for which indemnification is provided under this Section 8; then, and in each such case, the Company and the Shareholder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in proportion to the relative fault of the Company, on the one hand, and the Shareholder, on the other hand; provided, however, that, in any such case, no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation and no such indemnifying party will be required to contribute any amount in excess of the public offering price of all shares offered by it pursuant to such registration statement. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged 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 indemnities provided in this Section 8 shall survive the transfer of any Shares or the Earnout Shares by the Shareholder.

9. Reports Under Securities Exchange Act of 1934.
