                   NUMBER NINE VISUAL TECHNOLOGY CORPORATION

                                    WARRANT
                                    -------

                             Dated: March 31, 1999


     Number Nine Visual Technology Corporation, a Delaware corporation (the
"Company"), hereby certifies that, for value received, KA Investments LDC, or
its registered assigns ("Holder"), is entitled, subject to the terms set forth
below, to purchase from the Company up to a total of 195,000 shares of Common
Stock, $.01 par value per share (the "Common Stock"), of the Company (each such
share, a "Warrant Share" and all such shares, the "Warrant Shares") at an
exercise price equal to $3.45 per share (as adjusted from time to time as
provided in Section 9, the "Exercise Price"), at any time and from time to time
from and after the date hereof and through and including March 31, 2002 (the
"Expiration Date"), and subject to the following terms and conditions:

          1.   Registration of Warrant.  The Company shall register this
               -----------------------                                  
Warrant, upon records to be maintained by the Company for that purpose (the
"Warrant Register"), in the name of the record Holder hereof from time to time.
The Company may deem and treat the registered Holder of this Warrant as the
absolute owner hereof for the purpose of any exercise hereof or any distribution
to the Holder, and for all other purposes, and the Company shall not be affected
by notice to the contrary.

          2.   Registration of Transfers and Exchanges.
               --------------------------------------- 
<PAGE>
 
               (a) The Company shall register the transfer of any portion of
this Warrant in the Warrant Register, upon surrender of this Warrant, with the
Form of Assignment attached hereto duly completed and signed, to the Transfer
Agent or to the Company at the office specified in or pursuant to Section 3(b).
Upon any such registration or transfer, a new warrant to purchase Common Stock,
in substantially the form of this Warrant (any such new warrant, a "New
Warrant"), evidencing the portion of this Warrant so transferred shall be issued
to the transferee and a New Warrant evidencing the remaining portion of this
Warrant not so transferred, if any, shall be issued to the transferring Holder.
The acceptance of the New Warrant by the transferee thereof shall be deemed the
acceptance of such transferee of all of the rights and obligations of a holder
of a Warrant.

               (b) This Warrant is exchangeable, upon the surrender hereof by
the Holder to the office of the Company specified in or pursuant to Section 3(b)
for one or more New Warrants, evidencing in the aggregate the right to purchase
the number of Warrant Shares which may then be purchased hereunder. Any such New
Warrant will be dated the date of such exchange.

          3.   Duration and Exercise of Warrants.
               --------------------------------- 

               (a) This Warrant shall be exercisable by the registered Holder on
any business day before 8:00 P.M., New York City time, at any time and from time
to time on or after the date hereof to and including the Expiration Date. At
8:00 P.M., New York City time on the Expiration Date, the portion of this
Warrant not exercised prior thereto shall be and become void and of no value.
Prior to the Expiration Date, the Company may not call or otherwise redeem this
Warrant without the prior written consent of the Holder.

               (b) Subject to Sections 2(b), 6 and 10, upon surrender of this
Warrant, with the Form of Election to Purchase attached hereto duly completed
and signed, to the Company at its address for notice set forth in Section 12 and
upon payment of the Exercise Price multiplied by the number of Warrant Shares
that the Holder intends to purchase hereunder, in the manner provided hereunder,
all as specified by the Holder in the Form of Election to Purchase, the Company
shall promptly (but in no event later than 3 business days after the Date of
Exercise (as defined herein)) issue or cause to be issued and cause to be
delivered to or upon the written order of the Holder and in such name or names
as the Holder may designate, a certificate for the Warrant Shares issuable upon
such exercise, free of restrictive legends except (i) either in the event that a
registration statement covering the resale of the Warrant Shares and naming the
Holder as a selling stockholder thereunder is not then effective or the Warrant
Shares are not freely transferable without volume restrictions pursuant to Rule
144(k) promulgated under the Securities Act of 1933, as amended (the "Securities
Act"), or (ii) if this Warrant shall have been issued pursuant to a written
agreement between the original Holder and the Company, as required by such
agreement. Any person so designated 

                                      -2-
<PAGE>
 
by the Holder to receive Warrant Shares shall be deemed to have become holder of
record of such Warrant Shares as of the Date of Exercise of this Warrant.

               A "Date of Exercise" means the date on which the Company shall
have received (i) this Warrant (or any New Warrant, as applicable), with the
Form of Election to Purchase attached hereto (or attached to such New Warrant)
appropriately completed and duly signed, and (ii) payment of the Exercise Price
for the number of Warrant Shares so indicated by the holder hereof to be
purchased.

               (c) This Warrant shall be exercisable, either in its entirety or,
from time to time, for a portion of the number of Warrant Shares. If less than
all of the Warrant Shares which may be purchased under this Warrant are
exercised at any time, the Company shall issue or cause to be issued, at its
expense, a New Warrant evidencing the right to purchase the remaining number of
Warrant Shares for which no exercise has been evidenced by this Warrant.

          4.   Piggyback Registration Rights.  During the Effectiveness Period
               -----------------------------                                  
(as defined in the Registration Rights Agreement, of even date herewith, between
the Company and the original Holder), the Company may not file any registration
statement with the Securities and Exchange Commission (other than registration
statements of the Company filed on Form S-8 or Form S-4, each as promulgated
under the Securities Act, pursuant to which the Company is registering
securities pursuant to a Company employee benefit plan or pursuant to a merger,
acquisition or similar transaction including supplements thereto, but not
additionally filed registration statements in respect of such securities) at any
time when there is not an effective registration statement covering the resale
of the Warrant Shares and naming the Holder as a selling stockholder thereunder,
unless the Company provides the Holder with not less than 20 days notice of its
intention to file such registration statement and provides the Holder the option
to include any or all of the applicable Warrant Shares therein. The piggyback
registration rights granted to the Holder pursuant to this Section shall
continue until all of the Holder's Warrant Shares have been sold in accordance
with an effective registration statement or upon the Expiration Date. The
Company will pay all registration expenses in connection therewith.

          5.   Demand Registration Rights.  At any time during the term of this
               --------------------------                                      
Warrant when the Warrant Shares are not registered pursuant to an effective
registration statement, the Holder may make a written request for the
registration under the Securities Act (a "Demand Registration"), of all of the
Warrant Shares (the "Registrable Securities"), and the Company shall use its
best efforts to effect such Demand Registration as promptly as possible, but in
any case within 90 days thereafter. Any request for a Demand Registration shall
specify the aggregate number of Registrable Securities proposed to be sold and
shall also specify the intended method of disposition thereof. The right to
cause a registration of the Registrable Securities under this Section 5 shall be
limited to one such registration. In any registration initiated as a Demand
Registration, the Company will pay all of its registration expenses in

                                      -3-
<PAGE>
 
connection therewith. A Demand Registration shall not be counted as a Demand
Registration hereunder until the registration statement filed pursuant to the
Demand Registration has been declared effective by the Securities and Exchange
Commission and maintained continuously effective for a period of at least 360
days or such shorter period when all Registrable Securities included therein
have been sold in accordance with such registration statement, provided, however
that any days on which such registration statement is not effective or on which
the Holder is not permitted by the Company or any governmental authority to sell
Warrant Shares under such registration statement shall not count towards such
360 day period.

          6.   Payment of Taxes.  The Company will pay all U.S. documentary
               ----------------                                            
stamp taxes attributable to the issuance of Warrant Shares upon the exercise of
this Warrant; provided, however, that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the
registration of any certificates for Warrant Shares or Warrants in a name other
than that of the Holder.  The Holder shall be responsible for all other tax
liability that may arise as a result of holding or transferring this Warrant or
receiving Warrant Shares upon exercise hereof.

          7.   Replacement of Warrant.  If this Warrant is mutilated, lost,
               ----------------------                                      
stolen or destroyed, the Company shall issue or cause to be issued in exchange
and substitution for and upon cancellation hereof, or in lieu of and
substitution for this Warrant, a New Warrant, but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction and
indemnity, if requested, satisfactory to it.  Applicants for a New Warrant under
such circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

          8.   Reservation of Warrant Shares.  The Company covenants that it
               -----------------------------                                
will at all times reserve and keep available out of the aggregate of its
authorized but unissued Common Stock, solely for the purpose of enabling it to
issue Warrant Shares upon exercise of this Warrant as herein provided, the
number of Warrant Shares which are then issuable and deliverable upon the
exercise of this entire Warrant, free from preemptive rights or any other actual
contingent purchase rights of persons other than the Holder (taking into account
the adjustments and restrictions of Section 9). The Company covenants that all
Warrant Shares that shall be so issuable and deliverable shall, upon issuance
and the payment of the applicable Exercise Price in accordance with the terms
hereof, be duly and validly authorized, issued and fully paid and nonassessable.

          9.   Certain Adjustments.  The Exercise Price and number of Warrant
               -------------------                                           
Shares issuable upon exercise of this Warrant are subject to adjustment from
time to time as set forth in this Section 9. Upon each such adjustment of the
Exercise Price pursuant to this Section 9, the Holder shall thereafter prior to
the Expiration Date be entitled to purchase, at the Exercise Price resulting
from such adjustment, the number of Warrant Shares obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
Warrant 

                                      -4-
<PAGE>
 
Shares issuable upon exercise of this Warrant immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

               (a) If the Company, at any time while this Warrant is
outstanding, (i) shall pay a stock dividend (except scheduled dividends paid on
outstanding preferred stock as of the date hereof which contain a stated
dividend rate) or otherwise make a distribution or distributions on shares of
its Common Stock or on any other class of capital stock payable in shares of
Common Stock, (ii) subdivide outstanding shares of Common Stock into a larger
number of shares, or (iii) combine outstanding shares of Common Stock into a
smaller number of shares, the Exercise Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding before such event and of which the
denominator shall be the number of shares of Common Stock (excluding treasury
shares, if any) outstanding after such event. Any adjustment made pursuant to
this Section shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution
and shall become effective immediately after the effective date in the case of a
subdivision or combination, and shall apply to successive subdivisions and
combinations.

               (b) In case of any reclassification of the Common Stock, any
consolidation or merger of the Company with or into another person, the sale or
transfer of all or substantially all of the assets of the Company or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification, consolidation, merger, sale,
transfer or share exchange, and the Holder shall be entitled upon such event to
receive such amount of securities or property equal to the amount of Warrant
Shares such Holder would have been entitled to had such Holder exercised this
Warrant immediately prior to such reclassification, consolidation, merger, sale,
transfer or share exchange. The terms of any such consolidation, merger, sale,
transfer or share exchange shall include such terms so as to continue to give to
the Holder the right to receive the securities or property set forth in this
Section 9(b) upon any exercise following any such reclassification,
consolidation, merger, sale, transfer or share exchange.

               (c) If the Company, at any time while this Warrant is
outstanding, shall distribute to all holders of Common Stock (and not to holders
of this Warrant) evidences of its indebtedness or assets or rights or warrants
to subscribe for or purchase any security (excluding those referred to in
Sections 9(a), (b) and (d)), then in each such case the Exercise Price shall be
determined by multiplying the Exercise Price in effect immediately prior to the
record date fixed for determination of stockholders entitled to receive such
distribution by a fraction of which the denominator shall be the Exercise Price
determined as of the record date mentioned above, and of which the numerator
shall be such Exercise Price on such record date less the then fair market value
at such record date of the portion of such assets or evidence of 

                                      -5-
<PAGE>
 
indebtedness so distributed applicable to one outstanding share of Common Stock
as determined by the Company's independent certified public accountants that
regularly examines the financial statements of the Company (an "Appraiser").

               (d) If, at any time while this Warrant is outstanding, the
Company shall issue or cause to be issued rights or warrants to acquire or
otherwise sell or distribute shares of Common Stock for a consideration per
share less than the Exercise Price then in effect, other than issuances pursuant
to any (a) stockholder approved stock option or stock purchase program solely to
employees of the Company, (b) any acquisition, licensing joint venture or
strategic partnership not primarily for the purpose of raising capital, or (c)
conversion of any options, warrants or other convertible securities outstanding
on the date hereof, then, forthwith upon such issue or sale, the Exercise Price
shall be reduced to the price (calculated to the nearest cent) determined by
multiplying the Exercise Price in effect immediately prior thereto by a
fraction, the numerator of which shall be the sum of (i) the number of shares of
Common Stock outstanding immediately prior to such issuance, and (ii) the number
of shares of Common Stock which the aggregate consideration received (or to be
received, assuming exercise or conversion in full of such rights, warrants and
convertible securities) for the issuance of such additional shares of Common
Stock would purchase at the Exercise Price, and the denominator of which shall
be the sum of the number of shares of Common Stock outstanding immediately after
the issuance of such additional shares. Such adjustment shall be made
successively whenever such an issuance is made.

               (e) For the purposes of this Section 9, the following clauses
shall also be applicable:

                   (i) Record Date. In case the Company shall take a record of
                       -----------
the holders of its Common Stock for the purpose of entitling them (A) to receive
a dividend or other distribution payable in Common Stock or in securities
convertible or exchangeable into shares of Common Stock, or (B) to subscribe for
or purchase Common Stock or securities convertible or exchangeable into shares
of Common Stock, then such record date shall be deemed to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or sold
upon the declaration of such dividend or the making of such other distribution
or the date of the granting of such right of subscription or purchase, as the
case may be.

                   (ii) Treasury Shares.  The number of shares of Common Stock
                        ---------------                                       
outstanding at any given time shall not include shares owned or held by or for
the account of the Company, and the disposition of any such shares shall be
considered an issue or sale of Common Stock.

               (f) All calculations under this Section 9 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be.

                                      -6-
<PAGE>
 
               (g) Whenever the Exercise Price is adjusted pursuant to Section
9(c) above, the Holder, after receipt of the determination by the Appraiser,
shall have the right to select an additional appraiser (which shall be a
nationally recognized accounting firm), in which case the adjustment shall be
equal to the average of the adjustments recommended by each of the Appraiser and
such appraiser. The Holder shall promptly mail or cause to be mailed to the
Company, a notice setting forth the Exercise Price after such adjustment and
setting forth a brief statement of the facts requiring such adjustment. Such
adjustment shall become effective immediately after the record date mentioned
above.

               (h)  If:

                         (i)     the Company shall declare a dividend (or any
                                 other distribution) on its Common Stock; or

                         (ii)    the Company shall declare a special
                                 nonrecurring cash dividend on or a redemption
                                 of its Common Stock; or

                         (iii)   the Company shall authorize the granting to all
                                 holders of the Common Stock rights or warrants
                                 to subscribe for or purchase any shares of
                                 capital stock of any class or of any rights; or

                         (iv)    the approval of any stockholders of the Company
                                 shall be required in connection with any
                                 reclassification of the Common Stock of the
                                 Company, any consolidation or merger to which
                                 the Company is a party, any sale or transfer of
                                 all or substantially all of the assets of the
                                 Company, or any compulsory share exchange
                                 whereby the Common Stock is converted into
                                 other securities, cash or property; or

                         (v)     the Company shall authorize the voluntary
                                 dissolution, liquidation or winding up of the
                                 affairs of the Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, at least 30 calendar days prior
to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of Common Stock of record to be

                                      -7-
<PAGE>
 
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up; provided, however, that the failure to mail such notice or any
               --------  -------                                             
defect therein or in the mailing thereof shall not affect the validity of the
corporate action required to be specified in such notice.

          10.  Payment of Exercise Price.  The Holder may pay the Exercise Price
               -------------------------                                        
in one of the following manners:

               (a) Cash Exercise.  The Holder shall deliver immediately
                   -------------                                       
available funds; or

               (b) Cashless Exercise.  The Holder shall surrender this Warrant
                   -----------------   
to the Company together with a notice of cashless exercise, in which event the
Company shall issue to the Holder the number of Warrant Shares determined as
follows:

                         X = Y (A-B)/A
     where:
                         X = the number of Warrant Shares to be issued         
     to the Holder.

                         Y = the number of Warrant Shares with respect to which
                         this Warrant is being exercised.

                         A = the average of the closing sale prices of the
                         Common Stock for the five (5) trading days immediately
                         prior to (but not including) the Date of Exercise.

                         B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have been
commenced, on the issue date.

          11.  Fractional Shares.  The Company shall not be required to issue or
               -----------------                                                
cause to be issued fractional Warrant Shares on the exercise of this Warrant.
The number of full Warrant Shares which shall be issuable upon the exercise of
this Warrant shall be computed on the basis of the aggregate number of Warrant
Shares purchasable on exercise of this Warrant 

                                      -8-
<PAGE>
 
so presented. If any fraction of a Warrant Share would, except for the
provisions of this Section 11, be issuable on the exercise of this Warrant, the
Company shall pay an amount in cash equal to the Exercise Price multiplied by
such fraction.

          12.  Notices.  Any and all notices or other communications or
               -------                                                 
deliveries hereunder shall be in writing and shall be deemed given and effective
on the earliest of (i) the date of transmission, if such notice or communication
is delivered via facsimile at the facsimile telephone number specified in this
Section prior to 8:00 p.m. (New York City time) on a business day, (ii) the
business day after the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section later than 8:00 p.m. (New York City time) on any date and earlier than
11:59 p.m. (New York City time) on such date, (iii) the business day following
the date of mailing, if sent by nationally recognized overnight courier service,
or (iv) upon actual receipt by the party to whom such notice is required to be
given. The addresses for such communications shall be: (i) if to the Company, to
18 Hartwell Avenue, Lexington, MA 02421-3141, Attention: Chief Financial
Officer, or to facsimile no. (781) 869-7190, or (ii) if to the Holder, to the
Holder at the address or facsimile number appearing on the Warrant Register or
such other address or facsimile number as the Holder may provide to the Company
in accordance with this Section 12.

          13.  Warrant Agent.  The Company shall serve as warrant agent under
