              Grant
                of Option.
                The Board of Directors of the Company (the “Board”)
                hereby grants to the Participant named in the Notice of Stock Option
                Grant
                an option (the “Option”)
                to purchase the number of Shares set forth in the Notice of Stock
                Option
                Award, at the exercise price per Share set forth in the Notice of
                Stock
                Option Grant (the “Exercise
                Price”),
                and subject to the terms and conditions of the 2008 Equity Incentive
                Plan
                (the “Plan”),
                which is incorporated herein by reference. In the event of a conflict
                between the terms and conditions of the Plan and this Stock Option
                Award
                Agreement, the terms and conditions of the Plan shall
                prevail.

            

    

     

    If
      designated in the Notice of Stock Option Grant as an Incentive Stock Option
      (“ISO”),
      this
      Option is intended to qualify as an Incentive Stock Option as defined in Section
      422 of the Code. Nevertheless, to the extent that it exceeds the $100,000
      limitation rule of Code Section 422(d), this Option shall be treated as a
      Nonstatutory Stock Option (“NSO”).

              Exercise
                of Option.

            

    

     

    
      	 	
              i.

            	
              Right
                to Exercise.
                This Option may be exercised during its term in accordance with the
                Vesting Schedule set out in the Notice of Stock Option Award and
                with the
                applicable provisions of the Plan and this Award
                Agreement.

            

    

     

    
      	 	
              ii.

            	
              Method
                of Exercise.
                This Option shall be exercisable by delivery of an exercise notice
                in the
                form attached as Exhibit
                A
                (the “Exercise
                Notice”)
                which shall state the election to exercise the Option, the number
                of
                Shares with respect to which the Option is being exercised (the
                “Exercised
                Shares”),
                and such other representations and agreements as may be required
                by the
                Company. The Exercise Notice shall be accompanied by payment of the
                aggregate Exercise Price as to all Exercised Shares. This Option
                shall be
                deemed to be exercised upon receipt by the Company of such fully
                executed
                Exercise Notice accompanied by payment of the aggregate Exercise
                Price.

            

    

     

    No
      Shares
      shall be issued pursuant to the exercise of an Option unless such issuance
      and
      such exercise complies with applicable laws. Assuming such compliance, for
      income tax purposes the Shares shall be considered transferred to the
      Participant on the date on which the Option is exercised with respect to such
      Shares.

     

    
      	 	
              3.

            	
              Termination.
                This Option shall be exercisable for three months after the termination
                of
                the Relationship; provided,
                however,
                if the Relationship is terminated by the Company for “Cause”, the Option
                shall terminate immediately. Upon Participant’s death or disability, this
                Option may be exercised for six (6) months after the Relationship
                ceases.
                In no event may Participant exercise this Option after the Term/Expiration
                Date as provided above.

            

    

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    “Cause”
      shall mean conduct involving one or more of the following: (i) the substantial
      and continuing failure of the Participant, after notice thereof, to render
      services to the Company in accordance with the terms or requirements of the
      Participant’s Relationship with the Company; (ii) disloyalty, gross
      negligence, willful misconduct, dishonesty or breach of fiduciary duty to the
      Company; (iii) the commission of an act of embezzlement or fraud;
      (iv) deliberate disregard of the rules or policies of the Company which
      results in direct or indirect loss, damage or injury to the Company;
      (v) the unauthorized disclosure of any trade secret or confidential
      information of the Company; or (vi) the commission of an act which
      constitutes unfair competition with the Company or which induces any customer
      or
      supplier to break a contract with the Company.

              Lock-Up
                Period.
                Participant hereby agrees that, if so requested by the Company or
                any
                representative of the underwriters (the “Managing
                Underwriter”)
                in connection with any registration of the offering of any securities
                of
                the Company under the Securities Act, Participant shall not sell
                or
                otherwise transfer any Shares or other securities of the Company
                during
                the 180-day period (or such other period as may be requested in writing
                by
                the Managing Underwriter and agreed to in writing by the Company)
                (the
                “Market
                Standoff Period”)
                following the effective date of a registration statement of the Company
                filed under the Securities Act. The Company may impose stop-transfer
                instructions with respect to securities subject to the foregoing
                restrictions until the end of such Market Standoff Period.

              Restrictions
                on Exercise.
                This Option may not be exercised until such time as the Plan has
                been
                approved by the stockholders of the Company, or if the issuance of
                such
                Shares upon such exercise or the method of payment of consideration
                for
                such shares would constitute a violation of any applicable law.

              Non-Transferability
                of Option.
                This Option may not be transferred in any manner other than by will
                or by
                the laws of descent or distribution and may be exercised during the
                lifetime of Participant only by Participant. The terms of the Plan
                and
                this Award Agreement shall be binding upon the executors, heirs,

              United
                States Tax Consequences.
                Set forth below is a brief summary as of the date of this Option
                of some
                of the United States federal tax consequences of exercise of this
                Option
                and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE,
                AND
                THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE PARTICIPANT
                SHOULD
                CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING
                OF THE
                SHARES. 

            

    

     

    
      	 	
              i.

            	
              Exercise
                of ISO.
                If this Option qualifies as an Incentive Stock Option, there will
                be no
                regular federal income tax liability upon the exercise of the Option,
                although the excess, if any, of the Fair Market Value of the Shares
                on the
                date of exercise over the Exercise Price will be treated as an adjustment
                to the alternative minimum tax for federal tax purposes and may subject
                the Participant to the alternative minimum tax in the year of
                exercise.

            

    

     

    
      	 	
              ii.

            	
              Exercise
                of Nonstatutory Stock Option.
                There may be a regular federal income tax liability upon the exercise
                of a
                NSO. The Participant will be treated as having received compensation
                income (taxable at ordinary income tax rates) equal to the excess,
                if any,
                of the Fair Market Value of the Shares on the date of exercise over
                the
                Exercise Price. If the Participant is an employee or a former employee,
                the Company will be required to withhold from the Participant's
                compensation or collect from the Participant and pay to the applicable
                taxing authorities an amount in cash equal to a percentage of this
                compensation income at the time of exercise, and may refuse to honor
                the
                exercise and refuse to deliver Shares if such withholding amounts
                are not
                delivered at the time of exercise.

            

    

     

    
      	 	
              iii.

            	
              Disposition
                of Shares.
                In the case of a NSO, if Shares are held for at least one year, any
                gain
                realized on disposition of the Shares will be treated as long-term
                capital
                gain for federal income tax purposes. In the case of an Incentive
                Stock
                Option, if Shares transferred pursuant to the Option are held for
                at least
                one year after exercise and for at least two years after the Date
                of
                Grant, any gain realized on disposition of the Shares will also be
                treated
                as long-term capital gain for federal income tax purposes. If Shares
                purchased under an Incentive Stock Option are disposed of within
                one year
                after exercise or two years after the Date of Grant, any gain realized
                on
                such disposition will be treated as compensation income (taxable

              Notice
                of Disqualifying Disposition of Incentive Stock Option
                Shares.
                If this Option is an Incentive Stock Option, and if the Participant
                sells
                or otherwise disposes of any of the Shares acquired pursuant to the
                Incentive Stock Option on or before the later of (1) the date two
                years
                after the Date of Grant, or (2) the date one year after the date
                of
                exercise, the Participant shall immediately notify the Company in
                writing
                of such disposition. The Participant agrees that the Participant
                may be
                subject to income tax withholding by the Company on the compensation
                income recognized by the
                Participant.

            

    

     

    
      	 	
              v.

            	
              Withholding.
                Pursuant to applicable federal, state, local or foreign laws, the
                Company
                may be required to collect income or other taxes on the grant of
                this
                Option, the exercise of this Option, the lapse of a restriction placed
                on
                this Option or the Shares issued upon exercise of this Option, or
                at other
                times. The Company may require, at such time as it considers appropriate,
                that the Participant pay the Company the amount of any taxes which
                the
                Company may determine is required to be withheld or collected, and
                the
                Participant shall comply with the requirement or demand of the Company.
                In
                its discretion, the Company may withhold Shares to be received upon
                exercise of this Option or offset against any amount owed by the
                Company
                to the Participant, including compensation amounts, if in its sole
                discretion it deems this to be an appropriate method for withholding
                or
                collecting taxes.

                of Option.
                The Board of Directors of the Company (the “Board”)
                hereby grants to the Participant named in the Notice of 102 Stock
                Option
                Award an option (the “Option”)
                to purchase the number of Shares set forth in the Notice of 102 Stock
                Option Award, at the exercise price per Share set forth in the Notice
                of
                Stock Option Award (the “Exercise
                Price”),
                and subject to the terms and conditions of the 2008 Equity Incentive
                Plan
                and the TranSwitch Corporation Addendum to the 2008 Equity Incentive

                for Israeli Participants (the “Plan”),
                which is incorporated herein by reference. According to such Plan
                and
                under certain provisions, the Option will be deposited with a trustee
                approved by the Israeli income tax authorities for this purpose,
                (the
                “Trustee”),
                who will hold it in trust on the Participants behalf, all as set
                forth in
                Section 9 below. In the event of a conflict between the terms and
                conditions of the Plan and this Award Agreement, the terms and conditions
                of the Plan shall prevail.

              Right
                to Exercise.
                This Option may be exercised during its term in accordance with the
                Vesting Schedule set out in the Notice of Stock Option Award and
                with the
                applicable provisions of the Plan and this Award
                Agreement.

            

    

     

    
      	 	
              ii.

            	
              Method
                of Exercise.
                This Option shall be exercisable by delivery of an exercise notice
                in the
                form attached as Exhibit
                A
                (the “Exercise
                Notice”)
                which shall state the election to exercise the Option, the number
                of
                Shares with respect to which the Option is being exercised (the
                “Exercised
                Shares”),
                the Participant’s agreement to be subject to a right of first refusal with
                respect to Exercised Shares and such other representations and agreements
                as may be required by the Company. The Exercise Notice shall be
                accompanied by payment of the aggregate Exercise Price as to all
                Exercised
                Shares. This Option shall be deemed to be exercised upon receipt
                by the
                Company of such fully executed Exercise Notice accompanied by payment
                of
                the aggregate Exercise Price.

            

    

     

    No
      Shares
      shall be issued pursuant to the exercise of an Option unless such issuance
      and
      such exercise complies with applicable laws. Assuming such compliance, for
      income tax purposes the Shares shall be considered transferred to the
      Participant on the date on which the Option is exercised with respect to such
      Shares.

     

    
      	
            	
              3.

            	
              Termination.
                This Option shall be exercisable for three months after the termination
                of
                the Relationship; provided,
                however,
                if the Relationship is terminated by the Company for “cause”, the Option
                shall terminate immediately. Upon Participant’s death or disability, this
                Option may be exercised for six (6) months after the Relationship
                ceases.
                In no event may Participant exercise this Option after the Term/Expiration
                Date as provided above.

            

    

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    “Cause”
      shall mean conduct involving one or more of the following: (i) the substantial
      and continuing failure of the Participant, after notice thereof, to render
      services to the Company in accordance with the terms or requirements of the
      Participant’s Relationship with the Company; (ii) disloyalty, gross
      negligence, willful misconduct, dishonesty or breach of fiduciary duty to the
      Company; (iii) the commission of an act of embezzlement or fraud;
      (iv) deliberate disregard of the rules or policies of the Company which
      results in direct or indirect loss, damage or injury to the Company;
      (v) the unauthorized disclosure of any trade secret or confidential
      information of the Company; or (vi) the commission of an act which
      constitutes unfair competition with the Company or which induces any customer
      or
      supplier to break a contract with the Company.

                Period.
                Participant hereby agrees that, if so requested by the Company or
                any
                representative of the underwriters (the “Managing
                Underwriter”)
                in connection with any registration of the offering of any securities
                of
                the Company under the Securities Act, Participant shall not sell
                or
                otherwise transfer any Shares or other securities of the Company
                during
                the 180-day period (or such other period as may be requested in writing
                by
                the Managing Underwriter and agreed to in writing by the Company)
                (the
                “Market
                Standoff Period”)
                following the effective date of a registration statement of the Company
                filed under the Securities Act. The Company may impose stop-transfer
                instructions with respect to securities subject to the foregoing
                restrictions until the end of such Market Standoff Period.

              Restrictions
                on Exercise.
                This Option may not be exercised until such time as the Plan has
                been
                approved by the stockholders of the Company, or if the issuance of
                such
                Shares upon such exercise or the method of payment of consideration
                for
                such shares would constitute a violation of any applicable law.

              Non-Transferability
                of Option.
                This Option may not be transferred in any manner otherwise than by
                will or
                by the laws of descent or distribution and may be exercised during
                the
                lifetime of Participant only by Participant. The terms of the Plan
                and
                this Award Agreement shall be binding upon the executors, heirs,
                successors and assigns of the
                Participant.

              Term

                This Option may be exercised only within the Term set out in the
                Notice of
                Stock Option Award which Term may not exceed ten (10) years from
                the Date
                of Grant, and may be exercised during such Term only in accordance

                Tax Considerations.

            

    

     

    
      	
            	a.	
              Section
                102 of the Israeli Income Tax Ordinance and its Rules.
                The Option is subject to the provisions of Section 102 of the Israeli
                Income Tax Ordinance [New version], 1961 (the “Ordinance”
                and “Section
                102”,
                respectively), as well as the Income Tax Rules (Tax Relief in Issuance
                of
                Shares to Employees), 2003 (the “102
                Rules”),
                promulgated thereunder. The complete version of Section 102 and the
                102 Rules will be provided to the Participant, at the Participant’s
                request, by the Company’s
                Vice President, Human Resources.

            

    

     

    Accordingly,
      the Company elected the capital gain tax treatment of Section 102(b)(2) of
      the
      Ordinance (the “Capital
      Gains Route”)
      for
      the purpose of the taxation of the Participant’s income from the Option. In
      general, taxable income that should be attributed to the Participant as a result
      of the grant of the Option will be tax-free on the date of grant, but will
      be
      taxed on the sale of the Exercised Shares or transfer of Option or Exercised
      Shares from the Trustee to the Participant (a “Transfer”).
      In
      accordance with the Capital Gains Route, if the Option or the Exercised Shares
      are held in trust by the Trustee (see Section 9 below) until the lapse of 2
      years from the date of grant (the “Trust
      Period”),
      gains
      derived from the sale of Exercised Shares shall be classified as capital gains
      and taxed at a rate of only 25%, except
      for a
      benefit derived at the time of grant of the Option,
      equal
      to the difference between (a) the average closing price of the Company’s Share
      on NASDAQ during 30 trading days prior to the date of grant, and (b) the
      Exercise Price, and multiplied by the number of Exercised Shares. Such benefit
      shall be subject to tax at the time of sale of the Exercised Shares, or a
      Transfer, as ordinary income (i.e. taxed at marginal tax rates (up to 47% in
      2008) and will be subject to social security and national health insurance
      payments).

     

    At
      the
      time of sale of the Exercised Shares or a Transfer, the Participant shall be
      subject to tax, which will be calculated, in general, according to difference
      between (a) the market price (or the actual sale price) of the Exercised Shares
      at such time, and (b) the Exercise Price1 .
      Such
      tax shall be withheld at source by the Company (or by the Participant’s direct
      employer), in accordance with the provisions of the 102 Rules, and the transfer
      of Exercised Shares to the Participant is conditioned upon the payment of such
      tax.

    ________________________

    
      	1	
              The
                above tax description is a general summary only and does not refer
                to
                expenses involved with the exercise of Option
                and sale of Exercised Shares or changes in the Israeli Consumer Price
                Index or in currency exchange rates, which
                may impact the final tax
                calculation.

    The
      Participant shall not be entitled to sell the Exercised Shares or to execute
      a
      Transfer, prior to the lapse of the Trust Period. Furthermore, any and all
      rights issued in respect of the Exercised Shares, including bonus shares
      (“Rights”(,
      shall
      be deposited with the Trustee and held thereby until the lapse of the Trust
      Period, and such Rights shall be subject to the Capital Gains Route.
Notwithstanding
      the aforesaid, the
      Participant may
      sell Exercised Shares or Rights or execute a Transfer prior
      to
      the lapse of the Trust Period,
      provided, however, that tax is withheld at source by the Company in accordance
      with the 102 Rules. In such case, the Participant’s gains shall be classified
      as ordinary income and the
      Participant shall
      be subject to tax on such income at marginal tax rates (up to 47% in 2008)
      and
      will
      be subject to
      social security and national health insurance payments.

              b.

            	
              Trust.
                To
                secure performance of Israeli tax law requirements, the Shares to
                be
                issued to the Participant according to the Exercise Notice will be
                held in
                trust by the Trustee that was approved for this purpose by the Israeli
                tax
                authorities, who shall release them to the Participant only upon
                full
                compliance with the legal requirements and the terms of the Plan.
                For this
                purpose, a trust deed was signed between TranSwitch (Israel) Ltd.
                and the
                Trustee, a copy of which is attached hereto as Exhibit
                B
                (the “Trust
                Deed”).
                The conditions of the Trust Deed apply to the Option and any Exercised
                Shares issued to the Participant; thus, the Participant is required
                to
                carefully read the provisions of the said Trust
                Deed.
