 Ladies/Gentlemen: 
  
 1. General. TranSwitch
Corporation, a Delaware corporation (the “Company”), proposes to offer to exchange $114,113,000 aggregate principal amount of its outstanding 4 1/2% Convertible Existing Notes due 2005 (the “Existing Notes”) that are convertible into common stock, par value $0.001 per share, (the “Shares”) of the Company for $94,143,000
aggregate principal amount of 5.45% Convertible Plus Cash NotesSM due September 30, 2007 (the “Plus Cash Notes”). The Plus Cash Notes issued in the Exchange Offer are to be issued pursuant to an Indenture, dated as of September 30, 2003,
as amended or modified from time to time (the “Indenture”), between the Company and U.S. Bank National Association, as Trustee (the “Trustee”). Capitalized terms used herein without definition shall have their respective meanings
set forth in or pursuant to the Exchange Offer Materials (as defined herein). 
  
 2. Engagement as Dealer Manager. By this Dealer Manager Agreement (the “Agreement”), the Company hereby engages and appoints you as the exclusive Dealer Manager for the Exchange Offer and authorizes
you to act as such in connection with the Exchange Offer. 
  
 As
Dealer Manager you agree, in accordance with your customary practice, to use reasonable efforts to perform in connection with the Exchange Offer those services as are customarily performed by investment banking concerns in connection with similar
offers, including, without limitation, soliciting from individuals and institutions the tender of the Existing Notes pursuant to and in accordance with the terms and conditions of the Exchange Offer. You shall act as an independent contractor in
connection with the Exchange Offer with duties solely to the Company, and nothing herein contained shall constitute you as an agent of the Company in connection with the solicitation of the tender of Existing Notes pursuant to and in accordance with
the terms and conditions of the Exchange Offer; provided, however, that the Company hereby authorizes the Dealer Manager and/or one or more registered brokers or dealers chosen by the Dealer Manager, to act as the Company’s agent in making the
Exchange Offer to residents of any jurisdiction in which such agent designation may be necessary to comply with applicable law. Nothing in this Agreement shall constitute the Dealer Manager a partner or joint venturer with the Company or any of its
subsidiaries. On the basis of the representations and warranties and agreements of the Company contained herein and subject to and in accordance with the terms and conditions hereof and of the Exchange Offer, the Dealer Manager agrees to act in such
capacity.

 19 

 
statement or omission or alleged omission made in the Registration Statement, the Prospectus, the Schedule TO, any other Exchange Offer Materials, or any
amendment or supplement thereto, made in reliance upon and in conformity with written information furnished to the Company by you expressly for use in the Registration Statement, the Prospectus, the Schedule TO or any other Exchange Offer Materials
or any amendment or supplement thereto or in the preparation thereof. 
  
 The indemnity agreement in this Section 11(a) shall extend upon the same terms and conditions to, and shall inure to the benefit of, you and your affiliates and the partners, directors, officers, employees and agents of you and your
affiliates, and each person or entity, if any, who controls or is under common control with, you within the meaning of the Securities Act or the Exchange Act. This indemnity agreement shall be in addition to any liabilities which the Company may
otherwise have. 
  
 (b) You agree to indemnify and hold harmless
the Company against any losses, claims, damages or liabilities, joint or several, to which the Company may become subject under the Securities Act, the Exchange Act or otherwise, specifically including, but not limited to, losses, claims, damages or
liabilities (or actions in respect thereof) arising out of or based upon (i) any breach of any representation, warranty, agreement or covenant of yours herein contained, (ii) any untrue statement or alleged untrue statement of any material fact

of the Company, and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act. This indemnity agreement shall be in addition to any liabilities, which you may otherwise have. 
  
 (c) Promptly after receipt by an indemnified party under this Section 11 of
notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 11, notify the indemnifying party in writing of the commencement thereof, but the
omission so to notify the indemnifying party will not relieve such indemnifying party from any liability which it may have to any indemnified party 

  

 20 

 
for contribution or otherwise than under the indemnity agreement contained in this Section 11 or to the extent the indemnifying party is not prejudiced as a
proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in,
and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the
defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably
concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on
behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of
counsel, the indemnifying party will not be liable to such indemnified party under this Section 11 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified
party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with
local counsel), approved by the indemnifying party (the Company in the case of Section 11(a) and U.S. Bancorp Piper Jaffray Inc. in the case of Section 11(b)), representing the indemnified parties who are parties to such action), (ii) the
indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of such action, or (iii) the indemnifying party has authorized the
employment of counsel for the indemnified party at the expense of the indemnifying party, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. 
  
 (d) The indemnifying party under this Section 11 shall not be liable for any
settlement of any proceeding effected without its written consent, unless the indemnifying party shall have approved the terms of settlement; provided that such consent shall not be unreasonably withheld. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and
indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes (i) an unconditional release of such indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
  
 (e) In order to provide for just and equitable contribution in any action in which a claim for indemnification is made
pursuant to this Section 11 but it is judicially determined (by 

  

 21 

 
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 11 provides for indemnification in such case, all the parties hereto shall contribute to the aggregate losses, claims, damages or liabilities to
which they may be subject (after contribution from others) in such proportion so that you are responsible for the portion represented by the percentage that the maximum Dealer Manager’s fee payable to the Dealer Manager pursuant to Section 6
hereof bears to the value of the maximum amount of Plus Cash Notes issuable pursuant to the Exchange Offer, and the Company is responsible for the remaining portion, provided, however, that (i) you shall not be required to contribute any amount in
excess of the amount by which the fee paid to you pursuant to Section 6 hereof exceeds the amount of damages which you have been otherwise required to pay and (ii) no person guilty of a fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation. The contribution agreement in this Section 11(d) shall extend upon the same terms and conditions to, and shall
inure to the benefit of, each person, if any, who controls you or the Company within the meaning of the Securities Act or the Exchange Act and each officer of the Company who signed the Registration Statement and each director of the Company.

  
 12. Representations, Warranties, Covenants and Agreements
to Survive Delivery. All representations, warranties, covenants and agreements of the Company and you herein or in certificates delivered pursuant hereto, and the indemnity and contribution agreements contained in Section 11 hereof shall remain
operative and in full force and effect regardless of any investigation made by or on behalf of you or any person controlling you within the meaning of the Securities Act or the Exchange Act, or by or on behalf of the Company or any of its officers,
directors or controlling persons within the meaning of the Securities Act or the Exchange Act, and shall survive the completion of the Exchange Offer or termination of this Agreement. 
  
 13. Termination. This Agreement shall terminate upon the earliest to occur of (i) thirty days after the Expiration
Date, (ii) any of the conditions specified in Section 10 has not been fulfilled as of any date such condition is required to be fulfilled pursuant to Section 10 (and the Dealer Manager shall have notified the Company thereof), (iii) the date on
which the Company terminates or withdraws the Exchange Offer for any reason, or (iv) any modification to the business terms of the Exchange Offer in the Company’s sole and absolute discretion that results in the Dealer Manager withdrawing
pursuant to Section 5 hereof, (the earliest to occur of clauses (i), (ii), (iii) or (iv) being referred to as the “Termination Date”).

 Re: TranSwitch Corporation 
  
 Ladies and Gentlemen: 
  
 Reference is made to a Registration Statement on Form S-4 and Form S-3 of TranSwitch Corporation (the “Company”)
(as the same may now or hereafter exist or be amended, the “Registration Statement”) pursuant to which it is proposed that
$                     principal amount of the Company’s     % Convertible Senior Plus Cash NotesSM due 2007
(the “Notes”) will be exchanged for $                     principal amount of the Company’s 4 1/2% Convertible Notes due 2005 (the “Exchange Offer”), or on such other terms as described in the final
prospectus with respect to such offering for which U.S. Bancorp Piper Jaffray, Inc. (“Piper Jaffray”) will act as the dealer manager (the “Dealer Manager”) and pursuant to which it is proposed that there will be a public offering
of $                     of the Notes (the “Public Offering”) for which Piper Jaffray will act as the placement agent (the
“Placement Agent”). Shares of Common Stock, $0.001 par value per share, of the Company (“Common Stock”) are held by the undersigned. 
  

In order to induce Piper Jaffray, as the Dealer Manager that may participate in the Exchange Offer, and as the Placement Agent that may participate in
the Public Offering, to continue its efforts in connection with the Exchange Offer and the Public Offering, the undersigned hereby agrees not to, directly or indirectly, sell, offer to sell, contract to sell, pledge, grant any option for sale or
purchase of, agree to sell or otherwise dispose of (collectively “Disposition”), any shares of Common Stock, or any securities convertible into or exercisable for Common Stock (individually and collectively, the “Securities”),
beneficially owned by the undersigned now or acquired by the undersigned on or before the effective date of the Registration Statement (the “Effective Date”), or with respect to which the undersigned now has, or on or before the Effective
Date acquires, the power of Disposition, for a period commencing on the Effective Date and ending 90 days thereafter (the “Lock-Up Period”), without the prior written consent of Piper Jaffray; provided, however, that the foregoing
agreement shall not apply to (i) gifts to family members or charitable contributions of Common Stock or securities convertible into or exercisable for Common Stock made by the undersigned in transfers not involving a public distribution or public
offering, if the recipient of such gift or contribution agrees in writing as a condition precedent to such gift or contribution to be bound by the terms hereof, or (ii) transfers of Securities to “affiliates” of the transferor in transfers
not involving a public distribution or public offering, if the transferee agrees in writing as a condition precedent to such transfer to be 

  

 26 

 
bound by the terms hereof. The term “affiliate” shall have the meaning given such term in Rule 144 under the Securities Act of 1933. The transferor
shall notify Piper Jaffray in writing prior to the transfer and shall deliver the above-mentioned agreement on the part of the permitted transferee, in form and substance satisfactory to Piper Jaffray. During the Lock-Up Period, there shall be no
further transfer of Common Stock or securities convertible into or exercisable for Common Stock, by either the undersigned or any permitted transferee, except in accordance with this letter agreement. 
  
 The foregoing restriction has been expressly agreed to preclude the holder of
the Securities from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to or result in a Disposition of Securities during the Lock-Up Period, even if such Securities would be disposed of by someone other
than such holder. Such prohibited hedging or other transactions would include, without limitation, any short sale (whether or not against the box) or any purchase, sale or grant of any right (including, without limitation, any put or call option)
with respect to any Securities or with respect to any security (other than a broad-based market basket or index) that included, relates to or derives any significant part of its value from Securities. 
  
 In furtherance of the foregoing, the Company and its transfer agent are
hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this letter agreement. The undersigned also agrees and consents to the entry of stock transfer instructions with the
Company’s transfer agent against the transfer of any shares of Common Stock or securities convertible into or exercisable for Common Stock. 
  
 In addition, the undersigned hereby waives any rights with respect to the registration of Securities, including any “piggyback” or demand rights
for registration of the Securities under any federal or applicable state securities laws, that the undersigned may be entitled to exercise as a result of or in connection with the filing of the Registration Statement or the Exchange Offer or the
Public Offering generally, and further agrees that, without the prior written consent of Piper Jaffray, it will not, during the period commencing on the date hereof and ending 90 days after the Effective Date, make any demand for or exercise any
right with respect to, the registration of any Securities. 
  
 Whether or not the Exchange Offer or the Public Offering actually occurs depends upon a number of factors, including market conditions. Any Exchange Offer will only be made pursuant to a dealer-manager agreement, the terms of which are
subject to negotiation between the Dealer Manager and the Company. Any Public Offering will only be made pursuant to a placement agent agreement or purchase agreement, the terms of which are subject to negotiation between the Placement Agent and the
Company. 
  
 The undersigned intends to be legally bound hereby.

 The Registration

knowledge, no proceedings for that purpose are pending before or threatened by the Commission. 
  
 In the course of the preparation of the Registration Statement and the Prospectus, we have participated in conferences with officers, employees and other representatives of the Company, KPMG LLP, the Company’s
independent public accountants, David Gordon, patent counsel to the Company, and your representatives and counsel concerning the information contained in the Registration Statement and the Prospectuses. We have not, however, independently verified
and are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus. Based on our participation as described above, nothing has come
to our attention that would lead us to believe that the Registration Statement, including any Incorporated Document and other Exchange Offer Materials (except for financial statements, financial statement schedules, and other financial data included
therein, as to which we make no statement), at the time the Registration Statement became effective, contained an 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 therein, in the light of the circumstances under which they were made, not misleading, or that the Prospectus (except for financial statements, financial statement schedules, and other financial data included therein, as to which we
make no statement), as of its date or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

 1. General. TranSwitch Corporation, a Delaware corporation (the “Company”), proposes to offer for cash (the “New Money
Offering”) up to $20,000,000 aggregate principal amount of 5.45% Convertible Plus Cash NotesSM due September 30, 2007 (the “Plus Cash Notes”) that are convertible into common stock, par value $0.001 per share (the “Shares”)
of the Company to Holders who submit some or all of their Existing Notes in the Exchange Offer (the “Exchange Offer”). 
  
 In the event Holders submit indications of interest for more than $20,000,000 aggregate principal amount in the New Money Offering, the additional Plus
Cash Notes will be allocated at the discretion of the Placement Agent (as defined below) based on the amount of each Holder’s indication in the New Money Offering. The additional Plus Cash Notes issued in the New Money Offering are to be issued
pursuant to an Indenture, dated as of September 30, 2003, as amended or modified from time to time (the “Indenture”), between the Company, and U.S. Bank National Association, as trustee (the “Trustee”). Capitalized terms used
herein without definition shall have their respective meanings set forth in or pursuant to the Registration Statement (as defined herein), notwithstanding that such terms as used herein are not capitalized in the Registration Statement. 

 
 2. Appointment as Agent. By this Placement Agreement (the
“Agreement”), the Company hereby engages and appoints you as exclusive Placement Agent (the “Placement Agent”) for the New Money Offering and authorizes you to act as such in connection with the New Money Offering. 
  
 (a) Subject to the terms and conditions stated herein, the Company hereby
agrees that the Plus Cash Notes to be issued in the New Money Offering will be sold exclusively through the Placement Agent. The Company and Placement Agent agree that the Placement Agent may allow, and dealers may reallow, a discount not in excess
of 3.625% per Plus Cash Note in connection with the sale of additional Plus Cash Notes in the New Money Offering. The Placement Agent agrees to use its best efforts to obtain purchases from the Holders for any or all of the additional Plus Cash
Notes or to obtain purchases from current shareholders at a price of $1,000 per additional Plus Cash Note or any integral multiple of $1,000. 
  

 1 

 (b) The Company shall not sell or approve the solicitation of offers for the purchase of additional Plus
Cash Notes in excess of the amount which shall be authorized by the Company or in excess of the aggregate offering price of the Plus Cash Notes registered pursuant to the Registration Statement. 
  
 3. Registration Statement, Prospectus and Offering Materials. The
Company has prepared and filed with the Securities and Exchange Commission (the “Commission”), under the Securities Act of 1933, as amended (the “Securities Act”), the Trust Indenture Act of 1939, as amended (the

Offering; the Shares that may be issued solely at the Company’s option as payment of interest on the Plus Cash Notes issued in the New Money Offering; and the Shares issuable solely at the Company’s option as payment of the Plus Cash
amount. The term “Registration Statement” as used in this Agreement shall mean such registration statement, including financial statements, schedules and exhibits, in the form in which it becomes effective and, in the event of any
amendment thereto or the filing of any abbreviated registration statement pursuant to Rule 462(b) of the Rules and Regulations relating thereto after the effective date of such registration statement, shall also mean (from and after the
effectiveness of such amendment or the filing of such abbreviated registration statement) such registration statement as so amended, together with any such abbreviated registration statement. The term “Prospectus” as used in this Agreement
shall mean the final prospectus included in the Registration Statement. Notwithstanding the foregoing, if any revised prospectus shall be provided to you by the Company for use in connection with the New Money Offering that differs from the
Prospectus referred to in the immediately preceding sentence (whether or not such revised prospectus is required to be filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations), the term “Prospectus” shall refer to
such revised prospectus from and after the time it is first provided to you for such use. Any reference to the Registration Statement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant
to Item 12 of Form S-3 under the Securities Act, as of the date of the Registration Statement or the Prospectus, as the case may be, and any reference to any amendment or supplement to the Registration Statement or the Prospectus shall be deemed to

amendment or supplement thereto. The terms “supplement” and “amendment” or “supplemented” and “amended” as used herein with respect to the Prospectus shall include all documents deemed to be incorporated by
reference in the Prospectus that are filed subsequent to the date of the Prospectus and prior to the termination of the Exchange Offer by the Company with the Commission pursuant to the Exchange Act and the Rules and Regulations of the Commission

 4. Use of the Prospectus and Registration Statement. The Company authorizes the Placement Agent to
use the Prospectus in connection with the Cash Offer for such period of time as any such materials are required by law to be delivered in connection therewith. 
  

5. Withdrawal. In the event that the Company: (i) uses or permits the use of, or files with the Commission or any other Agency, or any amendment
or supplement to the Registration Statement or the Prospectus, and such document (a) has not been submitted to you previously for you and your counsel’s comments or (b) has been so submitted, and you or your counsel have made comments which
have not been reflected in a manner reasonably satisfactory to you or your counsel, or (ii) breaches, in any material respect, any of its representations, warranties, agreements or covenants herein, or (iii) amends or revises the New Money Offering
in a manner not reasonably acceptable to you, then you shall be entitled to withdraw as Placement Agent in connection with the New Money Offering without any liability or penalty to you and without loss of any right to indemnification or
contribution provided in Section 11 or to the payment of all fees and expenses payable under Sections 6 and 7 below which have accrued to the date of such withdrawal (it being agreed that in the event of any such withdrawal, for the purpose of

 (a) The Company agrees to indemnify and hold you harmless against any

respect thereof) arising out of or based upon (i) any breach of any representation, warranty, agreement or covenant of the Company herein contained; 

  

 16 

 
(ii) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, or any amendments or supplements thereto,
or 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, or (iii) any untrue statement or alleged untrue statement of any material fact contained
in any Prospectus or any amendment or supplement thereto, including any Incorporated Document, or the omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which
they were made, not misleading, and agrees to reimburse you for any legal or other expenses reasonably incurred by you in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the
Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration
Statement, or Prospectus, or any such amendment or supplement thereto, in reliance upon, and in conformity with, written information relating to you furnished to the Company by you, specifically for use in the preparation thereof. 
  
 The indemnity agreement in this Section 11(a) shall extend upon the same
terms and conditions to, and shall inure to the benefit of, you and your affiliates and the partners, directors, officers, employees and agents of you and your affiliates, and each person or entity, if any, who controls or is under common control
with, you within the meaning of the Securities Act or the Exchange Act. This indemnity agreement shall be in addition to any liabilities, which the Company may otherwise have. 
  
 (b) You agree to indemnify and hold harmless the Company against any losses, claims, damages or liabilities, joint or
several, to which the Company may become subject under the Securities Act, the Exchange Act or otherwise, specifically including, but not limited to, losses, claims, damages or liabilities (or actions in respect thereof) arising out of or based upon
(i) any breach of any representation, warranty, agreement or covenant of yours herein contained, (ii) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, or any amendments or supplements
thereto, or 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, or (iii) any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement and the Prospectus or any amendment or supplement thereto, or the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under
which they were made, not misleading, in the case of subparagraphs (ii) and (iii) of this Section 11(b) to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in
reliance upon, and in conformity with, written information furnished to the Company by you specifically for use in the Registration Statement, or any amendment or supplement thereto or in the preparation thereof, and you agree to reimburse the
Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action. 
  
 The indemnity agreement in this Section 11(b) shall extend upon the same terms and conditions to, and shall inure to the
benefit of, each officer of the Company who signed the 

  

 17 

 
Registration Statement and each director of the Company, and each person, if any, who controls the Company within the meaning of the Securities Act or the
Exchange Act. This indemnity agreement shall be in addition to any liabilities which you may otherwise have. 
  
 (c) Promptly after receipt by an indemnified party under this Section 11 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against an indemnifying party under this Section 11, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve such indemnifying
party from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 11 or to the extent the indemnifying party is not prejudiced as a proximate result of such
failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it
shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may
arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional
to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified
party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying
party will not be liable to such indemnified party under this Section 11 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved
by the indemnifying party (the Company in the case of Section 11(a) and U.S. Bancorp Piper Jaffray Inc. in the case of Section 11(b)), representing the indemnified parties who are parties to such action), (ii) the indemnifying party shall not have
employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of such action, or (iii) the indemnifying party has authorized the employment of counsel for the
indemnified party at the expense of the indemnifying party, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. 
  
 (d) The indemnifying party under this Section 11 shall not be liable for any settlement of any proceeding effected without
its written consent, unless the indemnifying party shall have approved the terms of settlement, provided that such consent shall not be unreasonably withheld. No indemnifying party shall, without the prior written consent of the indemnified party,
effect any settlement, compromise or consent to the entry of judgment in any pending or threatened 

  

 18 

 
action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by
such indemnified party, unless such settlement, compromise or consent includes (i) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
  
 (e) In order to provide for just and equitable contribution in any action in which a claim for indemnification is made pursuant to this Section 11 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 11 provides for indemnification in such case, all the parties hereto shall contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in
such proportion so that you are responsible for the portion represented by the percentage that the maximum Placement Agent’s fee payable to the Placement Agent pursuant to Section 6 hereof bears to the value of the maximum amount of Plus Cash
Notes issuable pursuant to the New Money Offering, and the Company is responsible for the remaining portion, provided, however, that (i) you shall not be required to contribute any amount in excess of the amount by which the fee paid to you pursuant
to Section 6 hereof exceeds the amount of damages which you have been otherwise required to pay and (ii) no person guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution
from any person who is not guilty of such fraudulent misrepresentation. The contribution agreement in this Section 11(d) shall extend upon the same terms and conditions to, and shall inure to the benefit of, each person, if any, who controls you or
the Company within the meaning of the Securities Act or the Exchange Act and each officer of the Company who signed the Registration Statement and each director of the Company. 
  
 12. Representations, Warranties, Covenants and Agreements to Survive Delivery. All representations, warranties,
covenants and agreements of the Company and you herein or in certificates delivered pursuant hereto, and the indemnity and contribution agreements contained in Section 11 hereof shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of you or any person controlling you within the meaning of the Securities Act or the Exchange Act, or by or on behalf of the Company or any of its officers, directors or controlling persons within the meaning of
the Securities Act or the Exchange Act, and shall survive the completion of the New Money Offering or termination of this Agreement. 
  
 13. Termination. 
  
 (a) This Agreement shall terminate upon the earliest to occur of (i) thirty days after the Expiration Date, (ii) any of the conditions specified in
Section 10 has not been fulfilled as of any date such condition is required to be fulfilled pursuant to Section 10 (and the Placement Agent shall have notified the Company thereof), (iii) the date on which the Company terminates or withdraws the New
Money Offering for any reason, or (iv) any modification to the business terms of the New Money Offering in the Company’s sole and absolute discretion that results in the Placement Agent withdrawing pursuant to Section 5 hereof, (the earliest to
occur of clauses (i), (ii), (iii) or (iv) being referred to as the “Termination Date”). 
  
  

 19 

 (b) Notwithstanding termination of this Agreement pursuant to subsection (a) above, the obligations of
the parties pursuant to Sections 6, 7 and 11 shall survive any termination of this Agreement. 
  
 If you elect to terminate this Agreement as provided in this Section 13, you shall promptly notify the Company by telephone, telecopy or telegram, in each case confirmed by letter. 
  
 14. Notices. All notices or communications hereunder, except as herein
otherwise specifically provided, shall be in writing and if sent to you shall be mailed, delivered, or telecopied (and confirmed by letter) to you c/o U.S. Bancorp Piper Jaffray Inc., 800 Nicollet Mall, Suite 800, Minneapolis, MN 55402-7020

their respective executors, administrators, successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person or entity, other than the parties hereto and their respective executors,

 May    , 2003 
  
 Re: TranSwitch Corporation 
  
 Ladies and
Gentlemen: 
  
 Reference is made to a Registration Statement on
Form S-4 and Form S-3 of TranSwitch Corporation (the “Company”) (as the same may now or hereafter exist or be amended, the “Registration Statement”) pursuant to which it is proposed that
$             principal amount of the Company’s     % Convertible Senior Plus Cash NotesSM due 2007 (the “Notes”) will be exchanged for
$             principal amount of the Company’s 4 1/2% Convertible Notes due 2005 (the “Exchange Offer”), or on such other terms as described in the final prospectus with respect to such offering for which U.S. Bancorp Piper Jaffray, Inc. (“Piper Jaffray”) will act
as the dealer manager (the “Dealer Manager”) and pursuant to which it is proposed that there will be a public offering of $             of the Notes (the “Public
Offering”) for which Piper Jaffray will act as the placement agent (the “Placement Agent”). Shares of Common Stock, $0.001 par value per share, of the Company (“Common Stock”) are held by the undersigned. 

 
 In order to induce Piper Jaffray, as the Dealer Manager that may
participate in the Exchange Offer, and as the Placement Agent that may participate in the Public Offering, to continue its efforts in connection with the Exchange Offer and the Public Offering, the undersigned hereby agrees not to, directly or
indirectly, sell, offer to sell, contract to sell, pledge, grant any option for sale or purchase of, agree to sell or otherwise dispose of (collectively “Disposition”), any shares of Common Stock, or any securities convertible into or
exercisable for Common Stock (individually and collectively, the “Securities”), beneficially owned by the undersigned now or acquired by the undersigned on or before the effective date of the Registration Statement (the “Effective
Date”), or with respect to which the undersigned now has, or on or before the Effective Date acquires, the power of Disposition, for a period commencing on the Effective Date and ending 90 days thereafter (the “Lock-Up Period”),
without the prior written consent of Piper Jaffray; provided, however, that the foregoing agreement shall not apply to (i) gifts to family members or charitable contributions of Common Stock or securities convertible into or exercisable for Common
Stock made by the undersigned in transfers not involving a public distribution or public offering, if the recipient of such gift or contribution agrees in writing as a condition precedent to such gift or contribution to be bound by the terms hereof,
or (ii) transfers of Securities to “affiliates” of the transferor in transfers not involving a public distribution or public offering, if the transferee agrees in writing as a condition precedent 

 
to such transfer to be bound by the terms hereof. The term “affiliate” shall have the meaning given such term in Rule 144 under the Securities Act
of 1933. The transferor shall notify Piper Jaffray in writing prior to the transfer and shall deliver the above-mentioned agreement on the part of the permitted transferee, in form and substance satisfactory to Piper Jaffray. During the Lock-Up
Period, there shall be no further transfer of Common Stock or securities convertible into or exercisable for Common Stock, by either the undersigned or any permitted transferee, except in accordance with this letter agreement. 
  
 The foregoing restriction has been expressly agreed to preclude the holder of
the Securities from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to or result in a Disposition of Securities during the Lock-Up Period, even if such Securities would be disposed of by someone other
than such holder. Such prohibited hedging or other transactions would include, without limitation, any short sale (whether or not against the box) or any purchase, sale or grant of any right (including, without limitation, any put or call option)
with respect to any Securities or with respect to any security (other than a broad-based market basket or index) that included, relates to or derives any significant part of its value from Securities. 
  
 In furtherance of the foregoing, the Company and its transfer agent are
hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this letter agreement. The undersigned also agrees and consents to the entry of stock transfer instructions with the
Company’s transfer agent against the transfer of any shares of Common Stock or securities convertible into or exercisable for Common Stock. 
  
 In addition, the undersigned hereby waives any rights with respect to the registration of Securities, including any “piggyback” or demand rights
for registration of the Securities under any federal or applicable state securities laws, that the undersigned may be entitled to exercise as a result of or in connection with the filing of the Registration Statement or the Exchange Offer or the
Public Offering generally, and further agrees that, without the prior written consent of Piper Jaffray, it will not, during the period commencing on the date hereof and ending 90 days after the Effective Date, make any demand for or exercise any
right with respect to, the registration of any Securities. 
  
 Whether or not the Exchange Offer or the Public Offering actually occurs depends upon a number of factors, including market conditions. Any Exchange Offer will only be made pursuant to a dealer-manager agreement, the terms of which are
subject to negotiation between the Dealer Manager and the Company. Any Public Offering will only be made pursuant to a placement agent agreement or purchase agreement, the terms of which are subject to negotiation between the Placement Agent and the
Company. 
  
 The undersigned intends to be legally bound hereby.

 The Registration
Statement was filed with the Commission prior to the Commencement Date and, to our knowledge, no refusal order preventing effectiveness, and after effectiveness, no stop order suspending effectiveness, has been issued by the Commission, and, to our
knowledge, no proceedings for that purpose are pending before or threatened by the Commission. 

 In the course of the preparation of the Registration Statement and the Prospectus, we have participated
in conferences with officers, employees and other representatives of the Company, KPMG LLP, the Company’s independent public accountants, David Gordon, patent counsel to the Company, and your representatives and counsel concerning the
information contained in the Registration Statement and the Prospectuses. We have not, however, independently verified and are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements
contained in the Registration Statement or the Prospectus. Based on our participation as described above, nothing has come to our attention that would lead us to believe that the Registration Statement, including any Incorporated Document (except
for financial statements, financial statement schedules, and other financial data included therein, as to which we make no statement), at the time the Registration Statement became effective, contained an 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 therein, in the light of the circumstances under which they were made, not misleading, or that the Prospectus (except for financial
statements, financial statement schedules, and other financial data included therein, as to which we make no statement), as of its date or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to
state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

documents relating to the Company’s patents, patent rights, inventions, trade secrets, know-how, proprietary techniques, trademarks, service marks, trade names and copyrights, (“Intellectual Property”) to the extent that they relate

Licenses” section of the Annual Report, and to the best of my knowledge and belief, duly hold the foreign patents and trademarks listed in the “Patents and Licenses” section of the Annual Report. 
  
 (iii) To the best of my knowledge and belief, for the last three years,
except as disclosed in the Prospectus, or as otherwise disclosed to you, the Company has not received any notice from any other person pertaining to or challenging the right of the Company to use any patents or trademarks owned or used by or
licensed to the Company.

belief, for the last three years, except as disclosed in the Prospectus, or as otherwise disclosed to you, the Company has conducted its business without claim of infringement of any United States or foreign patents or trademarks of others.

 (v) To the best of my knowledge and belief, for the last three years, other than pending patent and

or patent applications with respect to the Company’s products. 
  
 (vi) To the best of my knowledge and belief, for the last three years, except as otherwise disclosed to you, the Company has not threatened action or litigation against another party for infringement of Company’s patents or trademarks.

the Company’s annual report on Form 10K for the year ending December 31, 2002 as filed on March 17, 2003, and the section of the Company’s quarterly report on Form 10Q for the quarter ending March 31, 2003 as filed on May 9, 2003 entitled
“CERTAIN FACTORS THAT MAY AFFECT OUR FUTURE RESULTS—Our Failure to Protect Our Proprietary Rights, or the Costs of Protecting These Rights, May Harm Our Ability to Compete”, and the section of the Form S-3 Registration Statement dated

amendments or supplements thereto made by the Company prior to the Closing Date and brought to my attention, and insofar as they concern trademarks, patents or patent rights, or patent applications pertaining to the Company’s business or
products, I have no reason to believe that these sections include any untrue statement of a material fact or omit to state any material fact necessary to make the statements made therein not misleading.
