shareholders for purposes of mailing and receiving transmittal letters and
distributing consideration to the Alacrity shareholders (the "Exchange Agent").
                                                              --------------

     2.3  No Fractional TranSwitch Common Stock.  Notwithstanding any other
          -------------------------------------
provision of this Agreement, neither certificates nor script for fractional
shares of TranSwitch Common Stock shall be issued to any holder of Alacrity
Common Stock or Preferred Stock in the Merger and the holder thereof shall not
be entitled to any voting or other rights of a holder of shares or a fractional
share interest.  Each holder of shares of Preferred Stock or Alacrity Common
Stock who otherwise would have been entitled to receive a fraction of a share of
TranSwitch Common Stock shall receive in lieu thereof cash, without interest, in
an amount determined by multiplying such holder's fractional interest by the
Average Price.  All amounts of cash in respect of fractional interests which
have not been claimed at the end of three years from the Effective Time by
surrender of certificates for shares of Preferred Stock or Alacrity Common Stock
shall be repaid to the Surviving Corporation, subject to the provisions of
applicable escheat or similar laws, for the account of the holders entitled
thereto.

     2.4  Distribution of TranSwitch Common Stock.
          ---------------------------------------

          (a) As soon as practicable after the Effective Time, the Exchange
Agent shall distribute the TranSwitch Common Stock as provided in this Section
2.4.  TranSwitch shall deliver to the Exchange Agent one or more certificates
representing in the aggregate the number of shares of TranSwitch Common Stock
issuable in the Merger in sufficient time for the Exchange Agent to make

                                      -4-
<PAGE>

such distribution. The Exchange Agent shall not be entitled to vote or exercise
any rights of ownership with respect to any shares of TranSwitch Common Stock
held by it from time to time hereunder, except that it shall receive and hold
all dividends or other distributions paid or distributed with respect to such
shares for the account of the persons entitled thereto.

          (b) Within five business days after the Effective Time, TranSwitch
shall cause to be mailed to each holder of record of a certificate or
certificates (the "Certificates") which immediately prior to the Effective Time
                   ------------
represented outstanding shares of Preferred Stock or Alacrity Common Stock,
whose shares were converted into the right to receive shares of TranSwitch
Common Stock and cash (if any), (i) a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon receipt of the Certificates by the Exchange Agent, and
shall be in such form and have such other provisions as TranSwitch may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for certificates representing shares of TranSwitch
Common Stock and cash (if any).  Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by TranSwitch, with such letter of transmittal, duly completed and
validly executed in accordance with the instructions thereto, the holder of such
certificate shall be entitled to receive in exchange therefor a certificate
representing the number of whole shares of TranSwitch Common Stock and payment
in lieu of fractional shares which such holder has the right to receive (if
any), and the Certificate so surrendered shall forthwith be cancelled.  Until so
surrendered, each outstanding Certificate that, prior to the Effective Time,
represented shares of Preferred Stock and Alacrity Common Stock will be deemed
from and after the Effective Time, for all corporate purposes, to evidence only
the ownership of the number of full shares of TranSwitch Common Stock into which
such share of Preferred Stock and Alacrity Common Stock shall have been so
converted and the right to receive an amount in cash in lieu of the issuance of
any fractional shares (if any).  All other rights as an Alacrity shareholder
shall cease as of the Effective Time.  Unless and until any such outstanding
certificates for shares of Preferred Stock or Alacrity Common Stock shall be so
surrendered, no dividend (cash or stock) payable to holders of record of shares
of TranSwitch Common Stock as of any date subsequent to the Effective Time shall
be paid to the holder of any such outstanding certificate and all other rights
as a shareholder of TranSwitch shall be suspended, but upon such surrender of
such outstanding certificate there shall be paid to the record holder of the
certificate of shares of TranSwitch Common Stock in exchange therefor the amount
of dividends, if any, without interest and less any taxes which may have been
imposed thereon, that have therefore become payable with respect to the number
of those shares of TranSwitch Common Stock represented by such certificate
issued upon such surrender and exchange, and all other rights as shareholder of
TranSwitch shall thereafter be restored.

     2.5  Alacrity Stock Options.  At or prior to the Effective Time, TranSwitch
          ----------------------
and Alacrity shall take all action necessary to cause the assumption by
TranSwitch as of the Effective Time of the options to purchase Alacrity Common
Stock (the "Alacrity Stock Plan Options") and the warrants to purchase Preferred
            ---------------------------
Stock outstanding as of the Effective Time (the "Alacrity Warrants"), whether or
                                                 -----------------
not exercisable and whether or not vested (the Alacrity Stock Plan Options and
the Alacrity Warrants are referred to collectively as the "Outstanding Alacrity
                                                           --------------------
Options").  Each of the Outstanding Alacrity Options shall be converted without
-------
any action on the part of the holder thereof into an option to purchase shares
of TranSwitch Common Stock as of the Effective Time in such a manner that (a)
TranSwitch is, with respect to the Alacrity Stock Plan Options, "assuming a
stock option in a transaction to which Section 424(a) applies" within the
meaning of Section 424 of the Code or (b) to the extent that Section 424 of the
Code does not apply to such Outstanding Alacrity Options, the

                                      -5-
<PAGE>

assumption would otherwise be a transaction within Section 424 of the Code. The
number of shares of TranSwitch Common Stock that the holder of an assumed
Outstanding Alacrity Option shall be entitled to receive upon the exercise of
such option or warrant shall be a number of whole shares (rounded down to the
nearest whole share) determined by multiplying the number of shares of Alacrity
Common or Preferred Stock subject to such warrant or options, determined
immediately before the Effective Time, by the applicable Exchange Ratio. The
exercise price for each share of TranSwitch Common Stock subject to an assumed
Outstanding Alacrity Option shall be the amount (rounded up to the nearest whole
cent) obtained by dividing the exercise price per share of each Outstanding
Alacrity Option immediately before the Effective Time by the Exchange Ratio
applicable to each Outstanding Alacrity Option, but shall be not less than $.01.
The assumption and substitution of the Outstanding Alacrity Options as provided
herein shall not give the holders of such warrants or options additional
benefits which they did not have immediately prior to the Effective Time or
relieve the holders of any obligations or restrictions applicable to their
warrants or options or the shares obtainable upon exercise of the warrants or
options. Each Alacrity Stock Plan Option assumed by TranSwitch shall be
exercisable upon the same terms and conditions as under Alacrity's 1995 Stock
Plan and the applicable option agreement issued thereunder, except that (A) each
such Outstanding Alacrity Option shall be exercisable for that whole number of
shares of TranSwitch Common Stock set forth above and (B) the exercise price per
share of TranSwitch Common Stock shall be adjusted as set forth above.
TranSwitch shall (i) on or prior to the Effective Time, reserve out of its
unissued shares of Common Stock sufficient shares to provide for the exercise of
the Outstanding Alacrity Options, (ii) use all reasonable efforts to register
under the Securities Act, within thirty (30) days after the Effective Time,
those shares of TranSwitch Common Stock to be issued upon the exercise of the
Alacrity Stock Option Plan Options, which registration shall be effective under
a registration statement on Form S-8 or such other form as may be permitted
under the Securities Act, (iii) as promptly as practicable after the Effective
Time, but in any event not later than 15 business days after the Effective Time,
issue to each holder of an Outstanding Alacrity Option a document evidencing the
foregoing assumption by TranSwitch, and (iv) from and after the Effective Time,
upon exercise of the assumed Outstanding Alacrity Options in accordance with the
terms thereof, make available for issuance all shares of TranSwitch Common Stock
covered thereby. It is the intention of the parties that the Alacrity Stock Plan
Options assumed by TranSwitch qualify following the Effective Time as incentive
stock options as defined in Section 422 of the Code to the extent permitted
under Section 422 of the Code and to the extent the Alacrity Stock Plan Options
qualified as incentive stock options prior to the Effective Time.

     2.6  Closing of Stock Transfer Books.  Except pursuant to the exercise of
          -------------------------------
options and warrants outstanding on the date of this Agreement, the stock
transfer books of Alacrity shall be closed at the close of business on the tenth
(10) business day immediately preceding the Effective Time.  In the event of a
transfer of ownership of Preferred Stock or Alacrity Common Stock which is not
registered in the transfer records of Alacrity, the shares of TranSwitch Common
Stock and cash (if any) to be issued in the Merger as provided herein may be
delivered to a transferee, if the certificate representing such Preferred Stock
of Alacrity Common Stock is presented to the Exchange Agent, accompanied by all
documents required to evidence and effect such transfer and by payment of any
applicable stock transfer taxes.

     2.7  Dissenting Shares.  Shares of Preferred Stock or Alacrity Common Stock
          -----------------
that have not been voted for adoption of this Agreement and with respect to
which appraisal rights shall have been properly perfected in accordance with the
California GCL (the "Dissenting Shares") shall not be converted into the right
                     -----------------
to receive shares of TranSwitch Common Stock and cash (if any) in accordance

                                      -6-
<PAGE>

with this Agreement, at or after the Effective Time, unless and until the holder
of such Dissenting Shares withdraws his demand for such appraisal in accordance
with the California GCL or becomes ineligible for such appraisal.  If a holder
of Dissenting Shares shall withdraw in accordance with the California GCL his
demand for such appraisal or shall become ineligible for such appraisal, then,
as of the later of the Effective Time or the occurrence of such event, such
holder's Dissenting Shares shall cease to be Dissenting Shares and shall be
converted into the right to receive the shares of TranSwitch Common Stock and
cash (if any) into which his Preferred Stock or Alacrity Common Stock was
converted as of the Effective Time pursuant to this Agreement.  Any amounts to
be paid to holders of Dissenting Shares with respect to such Dissenting Shares
shall be paid by the Surviving Corporation.

     2.8  Escrow Shares.   (i) Ten percent (10%) of the Total TranSwitch Common
          -------------
Shares (ii) plus such number of shares of Total TranSwitch Common Shares which
shall equal ten percent (10%) of the TranSwitch Stock, as defined in the
Purchase Agreement (as defined in Section 9.2(p) hereof) (the "Escrow Shares")
                                                               -------------
will be deposited and held in escrow in accordance with the Escrow Agreement
attached as Exhibit 2.2 (the "Escrow Agreement") as the first source, but not
            -----------       ----------------
the sole source, of indemnification payments that may become due to TranSwitch
pursuant to Article X.  The Escrow Shares will be withheld on a pro rata basis
among the holders of the Outstanding Alacrity Shares. The exact number of Escrow
Shares held for the account of each Alacrity shareholder will be determined at
the Closing by the agreement in writing of TranSwitch and Alacrity. The delivery
of the Escrow Shares will be made on behalf of the holders of the Outstanding
Alacrity Shares in accordance with the provisions hereof, with the same force
and effect as if such shares had been delivered by TranSwitch directly to such
holders and subsequently delivered by such holders to the Escrow Agent. The
approval of this Agreement by shareholders of Alacrity will also constitute
their approval of the terms and provisions of the Escrow Agreement, which is an
integral term of the Merger.

                   REPRESENTATIONS AND WARRANTIES OF ALACRITY

adjustments, which will not be material either individually or in the aggregate
and except as described in the Section 3.6 of the Alacrity Disclosure Schedule).
As of the Unaudited Balance Sheet Date, there were no material liabilities,
claims or obligations of any nature, whether accrued, absolute, contingent,
anticipated or otherwise, whether due or to become due, that are not shown or

to have been withheld and paid in connection with amounts paid or owing to any
employee, creditor, stockholder, independent contractor, or other third party.
All Tax Returns filed by Alacrity were complete and correct in all respects.
None of the Tax Returns filed by Alacrity or Taxes payable by Alacrity have been
the subject of an audit, action, suit, proceeding, claim, examination,
deficiency or assessment by any Governmental Entity, and no such audit, action,
suit, proceeding, claim, examination, deficiency or assessment is currently
pending or, to the knowledge of Alacrity, threatened.  Alacrity is not currently
the beneficiary of any extension of time within which to file any Tax Return,
and Alacrity has not waived any statute of limitation with respect to any Tax or
agreed to any extension of time with respect to a Tax assessment or deficiency,
except as a result of obtaining an extension of time to file any Tax Return. All
material elections with respect to Taxes affecting Alacrity are set forth in the
Financial Statements or in Section 3.7 of the Alacrity Disclosure Schedule. None
of the Tax Returns filed by Alacrity contains a disclosure statement under
former Section 6661 of the Code or Section 6662 of the Code (or any similar
provision of state, local or foreign Tax law). Alacrity is not a party to any
Tax sharing agreement or similar arrangement.  Alacrity has never been a member
of a group filing a consolidated federal income Tax Return, or a consolidated,
combined or other affiliated group state, local or foreign Tax Return, and
Alacrity does not have any liability for the Taxes of any Person (other than
Alacrity) under Treasury Regulation

                                      -13-
<PAGE>

Section 1.1502-6 (or any corresponding provision of state, local or foreign Tax
law), as a transferee or successor, by contract, or otherwise.

          (c)  Alacrity is not a party to any agreement, contract, arrangement
or plan that has resulted or would result, separately or in the aggregate, in
the payment of (i) any "excess parachute payments" within the meaning of Section
280G of the Code (without regard to the exceptions set forth in Sections
280G(b)(4) and 280G(b)(5) of the Code) or (ii) any amount for which a deduction
would be disallowed or deferred under Section 162 or Section 404 of the Code.
Alacrity has not made any change in accounting method or practice and has not
agreed to make any adjustment under Section 481(a) of the Code (or any
corresponding provision of state, local or foreign law) by reason of a change in
accounting method or otherwise, and Alacrity will not be required to make any
such adjustment as a result of the transactions set forth in this Agreement.
Alacrity does not have and has not had a permanent establishment in any foreign
country, as defined in any applicable Tax treaty or convention between the
United States and such foreign country. None of the assets of Alacrity directly

Alacrity Disclosure Schedule.

          (d)  There are no Liens for Taxes (other than for Taxes not yet due
and payable) upon the assets of Alacrity.  The unpaid Taxes of Alacrity
attributable to all periods (or portions thereof) ending on or before the
Closing did not, as of the Unaudited Balance Sheet Date, exceed the reserve for
actual Taxes (as opposed to any reserve for deferred Taxes established to
reflect timing differences between book and Tax income) as shown on the
Unaudited Balance Sheet, and will not exceed such reserve as adjusted for the
passage of time through the Closing Date in accordance with reasonable past
custom and practice of Alacrity in filing its Tax Returns (taking into account
any Taxes incurred as a result of the transactions contemplated by this
Agreement).  Alacrity has not incurred and will not incur any Taxes subsequent
to the Unaudited Balance Sheet Date through the Closing except in the ordinary
course of business.  Section 3.7 of the Alacrity Disclosure Schedule sets forth
Alacrity's Tax basis in each of its assets or group thereof.  Alacrity is not a
party to any joint venture, partnership, limited liability company or other
arrangement or contract which could be treated as a partnership for federal
income tax purposes.

          (e)  Alacrity has never filed a consent pursuant to Section 341(f) of
the Code, relating to collapsible corporations.  Alacrity and its shareholders
have not made any election for Alacrity to be treated as an "S corporation", as
that term is defined in Section 1361(a) of the Code, for federal income tax
purposes or under the comparable provisions of the laws of California or any
other applicable jurisdiction.

          (f)  Reserved.

purposes of this representation and those set out in the succeeding subsections
of this Section 3.7, the "stock" of Alacrity shall include any interest (whether
represented by a certificate, instrument, or otherwise) that may be treated as
an equity interest in Alacrity under applicable principles of federal income tax
law.  In addition, at the Effective Time of the Merger, Alacrity will have no
outstanding warrants, options, or convertible securities or any other type of
right outstanding pursuant to which any Persons could acquire shares of Alacrity
stock or any other equity interest in Alacrity that, if exercised, could affect

assets and at least seventy percent (70%) of the fair market value of the gross
assets held by Alacrity before the Merger will continue to be held by Alacrity
after the Merger.  For the purpose of determining the percentage of Alacrity's
net and gross assets held by Alacrity after the Merger, the following assets
will be treated as property held by Alacrity before but not after the Merger:
(i) assets disposed of by Alacrity before or after the Merger and in
contemplation thereof (including, without limitation, any asset disposed of by

                                           -----------------

          (l) The liabilities of Alacrity have been incurred by Alacrity in the
ordinary course of business.

contemplation of the Merger (including without limitation pursuant to a plan or
intent existing during the Pre-Merger Period), acquired stock of Alacrity (other
than in exchange for Tiger Common Stock in the Merger or Alacrity capital stock)

                                   ARTICLE X

                                INDEMNIFICATION


     10.1 Indemnification Relating to Agreement.  Subject to Sections 10.4 and
          -------------------------------------
10.6, the Shareholders and, as an integral term of the Merger, all other
shareholders of Alacrity who accept the Total TranSwitch Common Shares and
execute the Escrow Agreement (which is a condition to receiving such
consideration), jointly and severally, hereby agree to defend, indemnify and
hold TranSwitch harmless from and against, and to reimburse TranSwitch with
respect to, any and all losses, damages, liabilities, claims, judgments,
settlements, fines, costs and expenses (including reasonable

                                      -39-
<PAGE>

attorneys' fees), determined as provided in Section 10.4 ("Indemnifiable
                                                           -------------
Amounts"), of every nature whatsoever incurred by TranSwitch (which will be
-------
deemed to include any of the foregoing incurred by the Surviving Corporation) by
reason of or arising out of or in connection with (i) any breach, or any claim
(including claims by parties other than TranSwitch) that constitutes a breach,
by Alacrity or any of the Shareholders of any representation or warranty of
Alacrity or the Shareholders contained in this Agreement or in any certificate
or other document delivered to TranSwitch pursuant to this Agreement, other than
any breach or related claim taken or not taken at the written direction of or
after consultation with and written concurrence of TranSwitch, (ii) the failure,
partial or total, of Alacrity or any of the Shareholders to perform any
agreement or covenant required by this Agreement to be performed by it or them
other than any breach or related claim taken or not taken at the written
direction of or after consultation with and written concurrence of TranSwitch
and (iii) any Tax liability, or asserted liability, of Alacrity attributable to
periods (or any portion thereof) ending on or prior to the Closing but only to
the extent such liabilities were not accrued for on the Unaudited Balance Sheet.
The foregoing obligations to indemnify TranSwitch will be determined without
regard to any right to indemnification to which any Person may have in his or
her capacity as an officer, director, employee, agent or any other capacity of
Alacrity, and no shareholder of Alacrity will be entitled to any indemnification
from Alacrity or the Surviving Corporation for amounts paid hereunder. There
will be no right of contribution or subrogation from TranSwitch or the Surviving
Corporation for indemnification payments made by or for the account of the
Shareholders.

     10.2  Third Party Claims.  With respect to any claims or demands by third
           ------------------
parties as to which TranSwitch may seek indemnification hereunder, other than
claims or demands covered by Section 10.3, whenever TranSwitch will have
received a written notice that such a claim or demand has been asserted or
threatened, TranSwitch will promptly notify the "Indemnification Representative"
(as designated in the Escrow Agreement) of such claim or demand and of the facts
within TranSwitch's knowledge that relate thereto within a reasonable time after
receiving such written notice.  The Indemnification Representative will then
have the right to defend, contest, negotiate or settle any such claim or demand
through counsel of his own selection, satisfactory to TranSwitch, and solely at
the Shareholders' own cost and expense, which costs and expenses will be payable
out of the property being held pursuant to the Escrow Agreement.
Notwithstanding the preceding sentence, the Indemnification Representative will
not settle, compromise, or offer to settle or compromise any such claim or
demand without the prior written consent of TranSwitch, which consent will not
be unreasonably withheld.   Without limiting TranSwitch's rights to object for
other reasons, TranSwitch may object to a settlement or compromise which
includes any provision which in its reasonable judgment may have an adverse
impact on or establish an adverse precedent for the Business Condition of
TranSwitch or any of its Subsidiaries. If the Indemnification Representative
gives notice to TranSwitch within twenty (20) calendar days after TranSwitch has
notified the Indemnification Representative that any such claim or demand has
been made in writing, that the Indemnification Representative elects to have
TranSwitch defend, contest, negotiate, or settle any such claim or demand, then
TranSwitch will have the right to contest and/or settle any such claim or demand
and seek indemnification pursuant to this Article X as to any Indemnifiable
Amounts; provided, however, that TranSwitch will not settle, compromise, or
offer to settle or compromise any such claim or demand without the prior written
consent (which may include a general or limited consent) of the Indemnification
Representative, which consent will not be unreasonably withheld.  If the
Indemnification Representative fails to give written notice to TranSwitch of his
intention to contest or settle any such claim or demand within twenty (20)
calendar days after TranSwitch has notified the Indemnification Representative
that any such claim or demand has been made in writing, or if any such

                                      -40-
<PAGE>

notice is given but any such claim or demand is not contested by the
Indemnification Representative within a reasonable time thereafter, TranSwitch
will have the right to contest and/or settle any such claim or demand in its
sole discretion and seek indemnification pursuant to this Article X as to any
Indemnifiable Amounts.

     10.3  Tax Contests. Notwithstanding any of the foregoing, TranSwitch will
           ------------
have the right to conduct any Tax audit or other Tax contest relating to the
Surviving Corporation. TranSwitch will conduct any such Tax audit or other Tax
contest in good faith.   With respect to any matters relating to such Tax audits
or other Tax contests as to which TranSwitch may seek indemnification hereunder,
TranSwitch shall consult with the Indemnification Representative and allow him
to comment before taking any position or making any written submission with any
Governmental Entity with regard to any Indemnifiable matter.

     10.4  Limitations.  Notwithstanding any other provision in this Article X,
           -----------
TranSwitch will be entitled to indemnification only to the extent that the
aggregate Indemnifiable Amounts (which shall be determined for all purposes of
this Article X disregarding any qualification in any representation or warranty
as to "materially" or "material") exceed Two Hundred Thousand Dollars
($200,000.00) (the "Threshold Amount"), provided that at such time as the amount
                    ----------------
to which TranSwitch is entitled to be indemnified exceeds the Threshold Amount,
TranSwitch shall be entitled to be indemnified up to the full Indemnifiable
Amounts including the Threshold Amount.  Any claim for Indemnifiable Amounts
hereunder shall be offset or reduced by the amount of any insurance proceeds
actually received by TranSwitch and/or the Surviving Corporation in respect of
such losses; provided, however, that nothing herein shall require TranSwitch or
             --------  -------
the Surviving Corporation to obtain or maintain any such insurance, nor to
proceed against any policies so obtained, in lieu of or prior to obtaining the
indemnification provided for in this Article X.  The aggregate amount to which
TranSwitch will be entitled to be indemnified will not exceed a dollar amount
equal to twenty-five percent (25%) of (i) Total TranSwitch Common Shares plus
(ii) TranSwitch Stock (as defined in the Purchase Agreement), valued at the
Average Price, and the liability of any single Shareholder for indemnification
obligations after the termination of the Escrow Agreement (whether such
termination is due to the depletion of amounts held in escrow pursuant to the
Escrow Agreement or to the passage of time) shall be further limited to such
Shareholder's pro rata share of any Indemnifiable Amounts based on the number of
shares of TranSwitch Common Stock received by such Shareholder relative to the
aggregate number of shares of TranSwitch Common Stock distributed in respect of
shares of Alacrity Common Stock and Preferred Stock; provided, however, that
there will be no limitation on the obligations of any person for Indemnifiable
Amounts arising out of criminal activity or intentional fraud or willful
misstatements or willful omissions by Alacrity or such person. Any Indemnifiable
Amounts payable by a shareholder of Alacrity pursuant to the preceding sentence
will be net of, and in addition to, the shareholder's portion of any portion of
the property held pursuant to the Escrow Agreement that is payable to
TranSwitch; provided, however, that TranSwitch will first seek reimbursement of
any Indemnifiable Amounts pursuant to the provisions of the Escrow Agreement,
but may seek indemnification hereunder with respect to any deficiency in any
Indemnifiable Amounts not satisfied by the property held pursuant to the Escrow
Agreement after the termination of the Escrow Agreement.

     10.5  Binding Effect.  The indemnification obligations contained in this
           --------------
Article X are an integral part of this Agreement and the Merger in the absence
of which TranSwitch would not have entered into this Agreement.

                                      -41-
<PAGE>

     10.6  Time Limit. The representations, warranties, covenants and agreements
           ----------
of Alacrity and the Shareholders set forth in this Agreement will survive the
Closing and the consummation of the transactions contemplated by this Agreement,
but any claims with respect thereto may be made only on or before the first
yearly anniversary of the date of this Agreement; provided, however, that claims
alleging fraud or willful misstatements or willful omissions of Alacrity or the
Shareholders may be made only on or before the third yearly anniversary of the
Closing Date and claims relating to Tax matters may be made only on or before
the expiration of the applicable Tax statute of limitations.

     10.7  Sole Remedy.  Notwithstanding any other provision in this Agreement
           -----------
to the contrary, the provisions of this Article X and the provisions of the
Escrow Agreement will be the sole and exclusive remedy of (and corresponding
liability of any shareholder of Alacrity, in such shareholder's capacity as
such, to) TranSwitch, Merger Sub and the Surviving Corporation for any damage,
claim, cause of action or right of any nature arising out of or relating to this
Agreement, the certificates or other documents executed or delivered herewith,
or the transactions contemplated hereby; provided, however, that nothing in this
Agreement or the Escrow Agreement will be deemed to limit any right or remedy
for criminal activity or fraud, or willful misstatements or willful omissions,
or breaches of covenants or inaccuracies in any representations or warranties
set forth in any other agreement contemplated by this Agreement, including any
Investment Agreement, Affiliate Agreement or employment agreement or non-
competition agreement or the Registration Rights Agreement.


                                  ARTICLE XI

breach by Alacrity or a Shareholder of any representation, warranty, covenant or
agreement set forth in this Agreement or other ancillary agreements, which

Section 9.2 and has not been cured within five (5) business days following

Agreement or other ancillary agreements, which breach would result in a failure
to satisfy the closing conditions contained in Section 9.3 and has not been
cured within five (5) business days following receipt by TranSwitch of notice of
such breach,

     11.4  Outside Date.  This Agreement may be terminated by TranSwitch alone

<PAGE>

provided, however, that the right to terminate this Agreement pursuant to the
preceding clause will not be available to any party whose failure to fulfill any
obligation under this Agreement has been a significant cause of, or resulted in,
the failure of the Effective Time to occur on or before such date.

their respective officers or directors, except that (i) the provisions of
Sections 8.4, 8.6, 8.7 and 12.2 will survive any such termination and
abandonment, and (ii) no party will be released or relieved from any liability
arising from the willful breach by such party prior to termination of any of its
representations, warranties, covenants or agreements as set forth in this
Agreement.


                                  ARTICLE XII

     Such addresses may be changed, from time to time, by means of a notice
given in the manner provided in this Section 12.3.

     12.4  Severability.  If any provision of this Agreement is held to be
           ------------
unenforceable for any reason, it will be modified rather than voided, if
possible, in order to achieve the intent of the parties to this Agreement to the
extent possible.  In any event, all other provisions of this Agreement will be
deemed valid and enforceable to the full extent.

     12.5  Survival of Representations and Warranties.  All representations and
           ------------------------------------------
warranties contained in this Agreement, including the exhibits and schedules
delivered pursuant to this Agreement, will survive the Effective Time, but any

     12.6  Assignment.  No party to this Agreement may assign, by operation of
           ----------
law or otherwise, all or any portion of its rights, obligations, or liabilities
under this Agreement without the prior written consent of Alacrity, Merger Sub
and TranSwitch, which consent may be withheld in the absolute discretion of the
party asked to grant such consent; provided however, that no such assignment
which materially adversely reflects the rights of a Shareholder will be made
without the written consent of such Shareholder.  Any attempted assignment by
Merger Sub or TranSwitch, on the one hand, or by Alacrity, on the other hand, in
violation of this Section 12.6 will be voidable and will entitle Alacrity or
TranSwitch, respectively, to terminate this Agreement at its option.

     12.7  Counterparts.  This Agreement may be executed in two or more
           ------------
partially or fully executed counterparts each of which will be deemed an
original and will bind the signatory, but all of which together will constitute
but one and the same instrument.  The execution and delivery of a Signature Page
to Agreement and Plan of Reorganization in the form annexed to this Agreement,
including a facsimile copy of the actual signature, by any party hereto who will
have been furnished the final form of this Agreement will constitute the
execution and delivery of this Agreement by such party.

     12.8  Amendment.  This Agreement may not be amended except by an instrument
           ---------
in writing executed by Alacrity, Merger Sub and TranSwitch; provided however,
that no such amendment which materially adversely affects the rights or
obligations of any Shareholder will be made without the written consent of such
Shareholder.

     12.9  Extension, Waiver.  At any time prior to the Effective Time, any
           -----------------
party hereto may, to the extent legally allowed: (i) extend the time for the
performance of any of the obligations or other acts of any other party hereto to
the party extending such time, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements, covenants or conditions for the benefit of such party contained
herein.  Any agreement on the part of a party hereto to any such extension or
waiver will be valid only if set forth in an instrument in writing signed on
behalf of such party.

     12.10 Interpretation.  When a reference is made in this Agreement to
           --------------
Sections, Exhibits or Schedules, such reference will be to a Section, Exhibit or
Schedule to this Agreement unless otherwise indicated.  The words "include,"
"includes," and "including" when used therein will be deemed in each case to be
followed by the words "without limitation."  The table of contents, index to
defined terms, and headings contained in this Agreement are for reference
purposes only and will not affect in any way the meaning or interpretation of
this Agreement.

     12.11 Knowledge.  For purposes of this Agreement, the term "knowledge"
           ---------                                             ---------
(including any derivation thereof such as "know" or "knowing" and regardless of
whether such word starts with an initial capital) in reference to Alacrity will
mean the knowledge of the directors and executive officers of Alacrity and the
Shareholders.

     12.12 Transfer, Sales, Documentary, Stamp and Other Similar Taxes.  Any
           -----------------------------------------------------------
and all transfer, sales, documentary, stamp and other similar Taxes imposed in
connection with the transactions contemplated by this Agreement will be borne by
the shareholders of Alacrity with respect to which such Tax relates (or if any
such Tax does not relate to particular shareholders, then it shall be borne by

                                      -45-

all of the shareholders).  At TranSwitch's discretion, the amount paid to any
Person pursuant to this Agreement will be reduced by the amount of Taxes payable
by such Person pursuant to this Section 12.12.  Any amounts so withheld will be
promptly remitted to the appropriate Governmental Authority.
