                                                                    ------------
                                                                                
                               SUMMARY OF RIGHTS
                                        

     On April 14, 1999, the Board of Directors of Data Translation, Inc. (the
"Company") declared a dividend of one fractional preferred share purchase right
 -------                                                                       
(a "Right") for each outstanding share of common stock, par value $0.01 per
    -----                                                                  
share (the "Common Shares"), of the Company.  The dividend is payable on April
            -------------                                                     
30, 1999 (the "Record Date") to the stockholders of record on that date.  Except
               -----------                                                      
as described below, each Right, when exercisable, entitles the registered holder
to purchase from the Company one one-hundredth of a share of Series A Junior
Participating Preferred Stock of the Company, par value $0.01 per share (the
"Preferred Shares"), at a price of $21 per one one-hundredth of a Preferred
 ----------------                                                          
Share (the "Purchase Price"), subject to adjustment or substitution of other
            --------------                                                  
securities of the Company in place of the Preferred Shares.  The description and
terms of the Rights are set forth in a Rights Agreement (the "Rights Agreement")
                                                              ----------------  
between the Company and BankBoston, N.A., as Rights Agent (the "Rights Agent").
                                                                ------------   

     Initially, the Rights will be attached to all certificates representing
Common Shares then outstanding, and no separate Rights certificates will be
distributed.  Until the earlier to occur of (i) 10 business days following a
public announcement that a person or group of affiliated or associated persons
(an "Acquiring Person") have acquired beneficial ownership of 15% or more of the
     ----------------                                                           
outstanding Common Shares (the date of such an announcement being a "Shares
                                                                     ------
Acquisition Date"), or (ii) 10 business days (or such later date as may be
----------------                                                          
determined by action of the Board of Directors prior to such time as any Person
becomes an Acquiring Person) following the commencement of, or announcement of
an intention to make, a tender offer or exchange offer the consummation of which
would result in the beneficial ownership by a person or group of 15% or more of
such outstanding Common Shares (in either case, (i) or (ii), the "Distribution
                                                                  ------------
Date"), the Rights will be evidenced, with respect to any of the Common Share
----                                                                         
certificates outstanding as of the Record Date, by such Common Share
certificates together with a copy of this Summary of Rights.

     The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferred with and only with the Common Shares.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
Common Share certificates issued after the Record Date upon transfer or new
issuance of Common Shares will contain a notation incorporating the Rights
Agreement by reference.  Until the Distribution Date (or earlier redemption or
expiration of the Rights), the surrender for transfer of any certificates for
Common Shares outstanding as of the Record Date, even without such notation or a
copy of this Summary of Rights being attached thereto, will also constitute the
transfer of the Rights associated with the Common Shares represented by such
certificate.  As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Rights Certificates") will be mailed to
                                     -------------------                    
holders of record of the Common Shares as of the

                                      -2-


close of business on the Distribution Date, and the separate Rights Certificates
alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date.  The Rights
will expire on April 30, 2009 (the "Final Expiration Date"), unless the Rights
                                    ---------------------                     
are earlier redeemed by the Company, as described below.

     The Purchase Price payable, and the number of Preferred Shares or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or warrants to subscribe for or purchase Preferred Shares at a price, or
securities convertible into Preferred Shares with a conversion price, less than
the then current market price of the Preferred Shares or (iii) upon the
distribution to holders of the Preferred Shares of evidences of indebtedness or
assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings or dividends payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

     The number of outstanding Rights and the number of one one-hundredths of a
Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a stock split of the Common Shares or a stock
dividend on the Common Shares payable in Common Shares or subdivisions,
consolidations or combinations of the Common Shares occurring, in any such case,
prior to the Distribution Date.

     Preferred Shares purchasable upon exercise of the Rights will not be
redeemable.  Each Preferred Share will be entitled to a minimum preferential
quarterly dividend payment of $1 per share but will be entitled to an aggregate
dividend of 100 times the dividend declared per Common Share.  In the event of
liquidation, the holders of the Preferred Shares will be entitled to a minimum
preferential liquidation payment of $100 per share but will be entitled to an
aggregate payment of 100 times the payment made per Common Share.  Each
Preferred Share will have 100 votes, voting together with the Common Shares.
Finally, in the event of any merger, consolidation or other transaction in which
Common Shares are exchanged, each Preferred Share will be entitled to receive
100 times the amount received per Common Share.  These rights are protected by
customary anti-dilution provisions.

     Because of the nature of the Preferred Shares' dividend, liquidation and
voting rights, the value of the one one-hundredth interest in a Preferred Share
purchasable upon exercise of each Right should approximate the value of one
Common Share.

     If, after the first date of public announcement by the Company or an
Acquiring Person that an Acquiring Person has become such, the Company is
involved in a merger or other business combination transaction in which the
<PAGE>
 
                                      -3-

Common Shares are exchanged or changed, or 50% or more of the Company's
consolidated assets or earning power are sold (in one transaction or a series of
transactions), proper provision will be made so that each holder of a Right
(other than an Acquiring Person) will thereafter have the right to receive, upon
the exercise thereof at the then current exercise price of the Right, that
number of shares of common stock of the acquiring company (or, in the event
there is more than one acquiring company, the acquiring company receiving the
greatest portion of the assets or earning power transferred) which at the time
of such transaction would have a market value of two times the exercise price of
the Right.

     If any person becomes an Acquiring Person, each holder of a Right will
thereafter have the right to receive upon exercise that number of Common Shares
having a market value of two times the exercise price of the Right.  Upon
                                                                     ----
occurrence of any of the events described in the immediately preceding sentence,
--------------------------------------------------------------------------------
any Rights that are, or (under certain circumstances specified in the Rights
----------------------------------------------------------------------------
Agreement) were, beneficially owned by any Acquiring Person shall immediately
-----------------------------------------------------------------------------
become null and void.
-------------------- 

     At any time after the occurrence of any such event and prior to the
acquisition by such person or group of 50% or more of the outstanding Common
Shares, the Board of Directors may exchange the Rights (other than Rights owned
by such person or group which have become void), in whole or in part, at an
exchange ratio of one Common Share, or one one-hundredth of a Preferred Share
(or of a share of a class or series of the Company's preferred stock having
equivalent rights, preferences and privileges), per Right (subject to
adjustment).

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.  No fractional Preferred Shares (other than fractions which
are integral multiples of one one-hundredth of a Preferred Share, which may, at
the election of the Company, be evidenced by depositary receipts) will be issued
and in lieu thereof, an adjustment in cash will be made based on the market
price of the Preferred Shares on the last trading day prior to the date of
exercise.

     At any time prior to the earlier of (i) the tenth day after a Shares
Acquisition Date, or (ii) the expiration of the Rights, the Board of Directors
may redeem the Rights in whole, but not in part, at a price of $0.001 per Right
(the "Redemption Price"). The redemption of the Rights may be made effective at
      ----------------                                                         
such time on such basis and with such conditions as the Board of Directors in
its sole discretion may establish.  Immediately upon any redemption of the
Rights, the right to exercise the Rights will terminate and the only right of
the holders of Rights will be to receive the Redemption Price.

     Other than those provisions relating to the principal economic terms of the
Rights, any of the provisions of the Rights Agreement may be amended by the
Board of Directors of the Company prior to the Distribution Date.  After the
Distribution Date, the provisions of the Rights Agreement may be amended by the
Board in order to cure any ambiguity, to make changes that do not adversely
affect

                                      -4-

the interests of holders of Rights (excluding the interests of any Acquiring
Person), or to shorten or lengthen any time period under the Rights Agreement;
provided, however, that no amendment to adjust the time period governing 
--------  -------                                             
redemption shall be made at such time as the Rights are not redeemable.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.

     A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to a Current Report on Form 8-K dated May ___,
1999.  A copy of the Rights Agreement is available free of charge from the
Company.  This summary description of the Rights does not purport to be complete
and is qualified in its entirety by reference to the Rights Agreement, which is
hereby incorporated herein by reference.
