I.  Sale of Series B Preferred Stock and Warrant to an Institutional Investor
    -------------------------------------------------------------------------

  On April 1, 1999, Number Nine Visual Technology Corporation (the "Company")
publicly disseminated a press release, which is attached hereto as Exhibit 99.1,
announcing, among other things, that, on March 31, 1999 (the "Closing Date"),
the Company was successful in raising $3,000,000 of capital pursuant to a
Convertible Preferred Stock Purchase Agreement (the "Agreement"), which is
attached hereto as Exhibit 4.1, with an institutional investor (the "Investor"),
whereby the Company agreed to issue and sell to the Investor and the Investor
agreed to purchase from the Company the following:

     (1)  Three hundred (300) shares of Series B Convertible Preferred Stock 
          of the Company (the "Series B Preferred");

     (2)  A Common Stock Purchase Warrant for the purchase of up to one hundred
          ninety-five thousand (195,000) shares of the Company's Common Stock,
          $.01 par value per share (the "Common Stock"), at an exercise price of
          $3.45 per share, exercisable until March 31, 2002 (the "Warrant," the
          Series B Preferred and the Warrant are referred to collectively as the
          "Securities").


  The Investor purchased the Securities from the Company for the aggregate
purchase price of three million dollars ($3,000,000). The net proceeds from the
sale of the Securities will be used for working capital purposes. The Company
issued the Securities to the Investor in reliance upon Regulation D under
Section 4(2) of the Securities Act of 1933, as amended.

  Pursuant to the terms of the Agreement, the Company and the Investor 
Registration Rights Agreement which is attached as Exhibit 4.2, whereby the
Company is obligated, among other things, to register the shares of Common Stock
underlying each of the Series B Preferred and the Warrant on a Registration
Statement on Form S-3 to be filed with the Securities and Exchange Commission
within 30 days of the Closing Date.

  For consulting services rendered in connection with the transaction
consummated under the Agreement, the Company has agreed to issue a warrant to
Brighton Capital, Ltd. to purchase up to thirty thousand (30,000) shares of
Common Stock at an exercise price of $3.45 per share exercisable until March 31,
2002 (the "Brighton Warrant").  A form of the Brighton Warrant is attached
hereto as Exhibit 4.3.

  A.  Terms of the Series B Preferred
      -------------------------------

  The following summary of the terms of the Series B Preferred is qualified in
its entirety by reference to the Certificate of Designations, Preferences and
Rights of the Series B Convertible Preferred Stock of Number Nine Visual
Technology Corporation (the "Certificate of Designation"), which is attached 
hereto as Exhibit 4.4.

  Holders of the Series B Preferred (each a "Holder" or collectively, the
"Holders") are entitled to receive, when and as declared by the Board of
Directors out of funds legally available, and the Company shall pay, cumulative
dividends at the rate per share of four percent (4%) per annum (the "Series B
Dividend") payable on a quarterly basis on March 31, June 30, September 30 and
December 31 of each year that such share is outstanding and on each day that a
Holder requests that his or her Series B Preferred be converted into Common
Stock (the "Conversion Date"), commencing on the earlier to occur of the
Conversion Date for such share and June 30, 1999. The Series B
<PAGE>
 
Dividend may be paid in cash or shares of Common Stock at the discretion of the
Company. Any Series B Dividend to be paid in cash that is not timely paid
accrues a late fee, which must be paid in cash, at the rate of eighteen percent
(18%) per annum. Under certain circumstances, the Company may not issue shares
of Common Stock in payment of a Series B Dividend. The Series B Preferred have
no voting rights.

  Subject to certain volume restrictions, each share of the Series B Preferred
is convertible into shares of Common Stock at the option of the Holder on or
after June 28, 1999 at the Conversion Price.  The Conversion Price for each
share of Series B Preferred in effect on any Conversion Date shall be the lesser
of (a) $4.14 or (b) 88% of the average of the ten (10) lowest per share market
values during the thirty (30) trading days immediately preceding the applicable
Conversion Date.  The Conversion Price is subject to certain anti-dilution
protection.

  Pursuant to the terms of the Series B Preferred, at the option of a Holder, up
to twenty-five percent (25%) of the Series B Preferred issued on the Closing
Date is convertible on or after July 28, 1999 (the "Initial Conversion Date").
On and after the first month anniversary of the Initial Conversion Date, a
Holder shall be entitled to convert up to fifty percent (50%) of the number of
shares of Series B Preferred issued to it on the Closing Date, on a cumulative
basis.  On or after the second month anniversary of the Initial Conversion Date,
a Holder shall be entitled to convert up to seventy-five (75%) of the number of
shares of Series B Preferred, on a cumulative basis.  On and after the third
month anniversary of the Initial Conversion Date, a Holder shall be entitled to
convert all of the shares of Series B Preferred on a cumulative basis.  Subject
to certain restrictions, all of the Series B Preferred shall be automatically
converted on the third anniversary of the Closing Date.

  The maximum number of shares that may be issued pursuant to the conversion of
the Series B Preferred, without the Company seeking shareholder approval for
such an issuance, is 19.9% of the shares of Common Stock issued and outstanding
on March 30, 1999, or 1,883,236 shares of Common Stock.  If on the Conversion
Date, the aggregate number of shares of Common Stock owed to a Holder would
equal or exceed 1,883,236, the Holder shall have the option to require the
Company to either (1) obtain the appropriate shareholder approval needed for
such issuance or (2) redeem the shares submitted for conversion that exceed the
maximum amount.

  If the Company fails to deliver to a Holder such Common Stock certificates as
required by the terms of the Series B Preferred, the Company shall pay to the
Holder, in cash, as liquidated damages, $5,000 for each trading day after such
third (3rd) trading day until such certificates are delivered.

  The Company has the right to redeem all or any portion of the Series B
Preferred which have not been previously redeemed pursuant to certain 
restrictions and terms set forth in Section 6 of the Certificate of Designation.

  Upon the occurrence of certain triggering events, each Holder shall have the
right to require the Company to redeem all or any portion of the Series B
Preferred.

Exhibit 4.5, is exercisable to purchase up to one hundred ninety five thousand
(195,000) shares of the Company's Common Stock at an exercise price of $3.45 per

hundred fifty dollars ($672,750), if exercised in full. The Warrant also grants

  On March 31, 1999, the Company also entered into a Loan and Security Agreement
with BankBoston, N.A. (the "Loan Agreement"), which is attached hereto as

BankBoston, N.A. for the payment of any dividends other than dividends on the
Series B Preferred. The Loan Agreement also contains certain financial
performance covenants, including among them, quarterly profitability targets for
the calendar fiscal quarters beginning June 30, 1999. The Loan Agreements

  Pursuant to the terms of the Loan Agreement, the Company also issued a warrant

Exhibit 4.6, which is exercisable to purchase up to two hundred eleven thousand
(211,000) shares of the Company's Common Stock at an exercise price of $2.86 per

               ------------------                                               
certificates, authorizations and permits issued by the appropriate Federal,
state or foreign regulatory authorities necessary to conduct their respective
businesses as described in the SEC Documents, except where the failure to
possess such permits could not, individually or in the aggregate, have or result
in a Material Adverse Effect ("Material Permits"), and neither the Company nor
                               ----------------                               
any such Subsidiary has received any notice of proceedings relating to the
revocation or modification of any Material Permit.

          (t)  Title.  Neither the Company nor any of the Subsidiaries own any
               -----                                                          
real property. The Company and the Subsidiaries have good and marketable title
to all personal property owned by them which is material to the business of the
Company and its Subsidiaries, in each case free and clear of all Liens, except
for Liens as do not materially affect the value of such property and do not
interfere with the use made and proposed to be made of such property by the
Company and its Subsidiaries. Any real property and facilities held under lease
by the Company and its Subsidiaries are held by them under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and proposed to be made of such property and buildings by the
Company and its Subsidiaries.

          (u)  Disclosure.  The Company confirms that it has not provided the
               ----------                                                    
Purchaser or its agents or counsel with any information that constitutes or
might constitute material non-public information.  The Company understands and
confirms that the Purchaser shall be relying on the foregoing representations in
effecting transactions in securities of the Company. All disclosure provided to
the Purchaser regarding the Company, its business and the transactions
contemplated hereby, including the  Schedules to this Agreement, furnished by or
on behalf of the Company are true and correct and do not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading.

      2.2 Representations and Warranties of the Purchaser.  The Purchaser hereby
          -----------------------------------------------                       
represents and warrants to the Company as follows:

          (a)  Organization; Authority.  The Purchaser is a corporation duly

organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation with the requisite corporate power and
authority, to enter into and to consummate the transactions contemplated by the
Transaction Documents and otherwise to carry out its obligations thereunder. The
purchase by the Purchaser of the Securities hereunder has been duly authorized
by all necessary action on the part of the Purchaser. Each of this Agreement and
the Registration Rights Agreement has been duly executed and delivered by the
Purchaser and constitutes the valid and legally binding obligation of the
Purchaser, enforceable against it in accordance with its terms.

          (b) Investment Intent.  The Purchaser is acquiring the Securities for
              -----------------                                                
its own account for investment purposes only and not with a view to or for
distributing or reselling such Securities or any part thereof or interest
therein, without prejudice, however, to the Purchaser's right, subject to the
provisions of this Agreement and the Registration Rights Agreement, at all times
to sell or otherwise dispose of all or any part of such Securities pursuant to
an effective registration statement under the Securities Act and in compliance
with applicable state securities laws or under an exemption from such
registration.

          (c)  Purchaser Status.  At the time the Purchaser was offered the
               ----------------                                            
Shares and the Warrant, it was, and at the date hereof it is, and at each
exercise date under the Warrant, it will be, an "accredited investor" as defined
in Rule 501(a) under the Securities Act.

          (d)  Experience of the Purchaser.  The Purchaser, either alone or
               ---------------------------                                 
together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating
the merits and risks of the prospective investment in the Securities, and has so
evaluated the merits and risks of such investment.

          (e)  Ability of the Purchaser to Bear Risk of Investment.  The
               ---------------------------------------------------      
Purchaser is able to bear the economic risk of an investment in the Securities
and, at the present time, is able to afford a complete loss of such investment.

          (f)  Access to Information.  The Purchaser acknowledges that it has
               ---------------------                                         
reviewed the Disclosure Materials and has been afforded (i) the opportunity to
ask such questions as it has deemed necessary of, and to receive answers from,
representatives of the Company concerning the terms and conditions of the
offering of the Securities and the merits and risks of investing in the
Securities; (ii) access to information about the Company and the Company's
financial condition, results of operations, business, properties, management and
prospects sufficient to enable it to evaluate its investment; and (iii) the
opportunity to obtain such additional information which the Company possesses or
can acquire without unreasonable effort or expense that is necessary to make an
informed investment decision with respect to the investment and to verify the
accuracy and completeness of the information contained in the Disclosure
Materials.  Neither such inquiries nor any other investigation conducted by or
on behalf of such Purchaser or its representatives or counsel shall modify,
amend or affect such Purchaser's right to rely on the truth, accuracy and
completeness of the Disclosure Materials and the Company's representations and
warranties contained in the Transaction Documents.

          (g)  General Solicitation.  The Purchaser is not purchasing the
               --------------------                                      
Securities as a result of or subsequent to any advertisement, article, notice or
other communication regarding the Securities published in any newspaper,
magazine or similar media or broadcast over television or radio or presented at
any seminar or any other general solicitation or general advertisement.

          (h)  Reliance.  The Purchaser understands and acknowledges that (i)
               ---------                                                      
the Securities are being offered and sold to it without registration under the
Securities Act in a 

                                      -9-
<PAGE>
 
private placement that is exempt from the registration provisions of the
Securities Act and (ii) the availability of such exemption, depends in part on,
and the Company will rely upon the accuracy and truthfulness of, the foregoing
representations and the Purchaser hereby consents to such reliance.

          The Company acknowledges and agrees that the Purchaser makes no
representations or warranties with respect to the transactions contemplated
hereby other than those specifically set forth in this Section 2.2.


                                  ARTICLE III
                        OTHER AGREEMENTS OF THE PARTIES

     3.1  Transfer Restrictions.  (a) Securities may only be disposed of
          ---------------------                                         
pursuant to an effective registration statement under the Securities Act, to the
Company or pursuant to an available exemption from or in a transaction not
subject to the registration requirements of the Securities Act. In connection
with any transfer of Securities other than pursuant to an effective registration
statement or to the Company, except as otherwise set forth herein, the Company
may require the transferor thereof to provide to the Company an opinion of
counsel selected by the transferor, the form and substance of which opinion
shall be reasonably satisfactory to the Company, to the effect that such
transfer does not require registration of such transferred securities under the
Securities Act. Notwithstanding the foregoing, the Company hereby consents to
and agrees to register on the books of the Company and with any transfer agent
for the securities of the Company any transfer of Securities by the Purchaser to
an Affiliate of the Purchaser or to one or more funds under common management
with the Purchaser, and any transfer among any such Affiliates or one or more
funds, provided that the transferee certifies to the Company that it is an
"accredited investor" as defined in Rule 501(a) under the Securities Act and
that it is acquiring the Securities solely for investment purposes.  Any such
transferee shall agree in writing to be bound by the terms of this Agreement and
shall have the rights of the Purchaser under this Agreement and the Registration
Rights Agreement.

          (b)  The Purchaser agrees to the imprinting, so long as is required by
this Section 3.1(b), of the following legend on the Securities:

          NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE
     SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN REGISTERED WITH THE
     SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY
     STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES
     ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT
     BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
     UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN
     A TRANSACTION NOT SUBJECT TO, 

                                     -10-
<PAGE>
 
     THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
     APPLICABLE STATE SECURITIES LAWS.

          Underlying Shares shall not contain the legend set forth above nor any
other legend if the conversion of Shares, the payment of dividends thereon, and
exercise of the Warrant or other issuances of Underlying Shares as contemplated
hereby, by the Certificate of Designation or the Warrant occurs at any time
while an Underlying Securities Registration Statement is effective under the
Securities Act or, in the event there is not an effective Underlying Securities
Registration Statement, at such time, in the opinion of counsel to the Company,
such legend is not required under applicable requirements of the Securities Act
(including judicial interpretations and pronouncements issued by the staff of
the Commission). The Company shall cause its counsel to issue the legal opinion
included in the Transfer Agent Instructions to the Company's transfer agent on
the day that the Underlying Securities Registration Statement is declared
effective by the Commission.  The Company agrees that, in the event any
Underlying Shares are issued with a legend in accordance with this Section
3.1(b), it will, within three (3) Trading Days after request therefor by the
Purchaser, provide the Purchaser with a certificate or certificates representing
such Underlying Shares, free from such legend at such time as such legend would
not have been required under this Section 3.1(b) had such issuance occurred on
the date of such request.  The Company may not make any notation on its records
or give instructions to any transfer agent of the Company which enlarge the
restrictions of transfer set forth in this Section.

      3.2 Acknowledgment of Dilution.  The Company acknowledges that the
          --------------------------                                    
issuance of the Underlying Shares upon (i) conversion of the Shares and payment
of dividends thereon in accordance with the terms of the Certificate of
Designation, and (ii) exercise of the Warrant in accordance with its terms, will
result in dilution of the outstanding shares of Common Stock, which dilution may
be substantial under certain market conditions.  The Company further
acknowledges that its obligation to issue Underlying Shares upon (x) conversion
of the Shares and payment of dividends thereon in accordance with the terms of
the Certificate of Designation, and (y) exercise of the Warrant in accordance
with its terms, is unconditional and absolute, subject to the limitations set
forth herein in the Certificate of Designation or pursuant to the Warrant,
regardless of the effect of any such dilution, subject to stockholder approval
requirements of the NASDAQ that are not required to be obtained prior to the
issuance of the Shares.

     3.3  Furnishing of Information.  As long as the Purchaser owns Securities,
          -------------------------                                            
the Company covenants to timely file (or obtain extensions in respect thereof
and file within the applicable grace period) all reports required to be filed by
the Company after the date hereof pursuant to Section 13(a) or 15(d) of the
Exchange Act. As long as the Purchaser owns Securities, if the Company is not
required to file reports pursuant to such sections, it will prepare and furnish
to the Purchaser and make publicly available in accordance with Rule 144(c)
promulgated under the Securities Act such information as is required for the
Purchaser to sell the Securities under Rule 144 promulgated under the Securities
Act. The Company further

                                     -11-
<PAGE>
 
covenants that it will take such further action as any holder of Securities may
reasonably request, all to the extent required from time to time to enable such
Person to sell Underlying Shares without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 promulgated under
the Securities Act, including the legal opinion referenced above in this
Section. Upon the request of any such Person, the Company shall deliver to such
Person a written certification of a duly authorized officer as to whether it has
complied with such requirements.

      3.4 Integration.  The Company shall not, and shall use its best efforts to
          -----------                                                           
ensure that, no Affiliate shall, sell, offer for sale or solicit offers to buy
or otherwise negotiate in respect of any security (as defined in Section 2 of
the Securities Act) that would be integrated with the offer or sale of the
Securities in a manner that would require the registration under the Securities
Act of the sale of the Securities to the Purchaser.

      3.5 Increase in Authorized Shares.  If on any date the Company would be,
          -----------------------------                                       
if a notice of conversion or exercise (as the case may be) were to be delivered
on such date, precluded from (a) issuing 200% of the number of Underlying Shares
as would then be issuable upon a conversion in full of the Shares and as payment
of any accrued and unpaid dividends in respect thereof in shares of Common
Stock, or (b) issuing the number of Underlying Shares upon exercise in full of
the Warrant, subject to the limitations on the Company's obligation to issue
shares of Common Stock pursuant to Sections 5(a)(iii)(B) and (C) of the
Certificate of Designation (the "Current Required Minimum"), in either case, due
                                 ------------------------                       
to the unavailability of a sufficient number of authorized but unissued or
reserved shares of Common Stock, then the Board of Directors of the Company
shall promptly (and in any case, within 45 Business Days from such date) prepare
and mail to the stockholders of the Company proxy materials requesting
authorization to amend the Company's Certificate of Incorporation to increase
the number of shares of Common Stock which the Company is authorized to issue to
at least such number of shares as reasonably requested by the Purchaser in order
to provide for such number of authorized and unissued shares of Common Stock to
enable the Company to comply with its issuance, conversion exercise and
reservation of shares obligations as set forth in this Agreement, the
Certificate of Designation and the Warrant (the sum of (x) the number of shares
of Common Stock then outstanding plus all shares of Common Stock issuable upon
exercise of all outstanding options, warrants and convertible instruments, and
(y) the Current Required Minimum, shall be a reasonable number).  In connection
therewith, the Board of Directors shall (a) adopt proper resolutions authorizing
such increase, (b) recommend to and otherwise use its best efforts to promptly
and duly obtain stockholder approval to carry out such resolutions (and hold a
special meeting of the stockholders no later than the 60/th/ day after delivery
of the proxy materials relating to such meeting) and (c) within five (5)
Business Days of obtaining such stockholder authorization, file an appropriate
amendment to the Company's Certificate of Incorporation to evidence such
increase.

      3.6 Reservation and Listing of Underlying Shares.  (a) The Company shall
          --------------------------------------------                        
(i) not later than the fifth (5th)Business Day following the Closing Date
prepare and file with the 

                                     -12-
<PAGE>
 
NASDAQ (and such other national securities exchange or market or trading or
quotation facility on which the Common Stock is then listed) an additional
shares listing application covering a number of shares of Common Stock which is
not less than the Initial Minimum, (ii) take all steps necessary to cause such
shares of Common Stock to be approved for listing in the NASDAQ (as well as on
any such other national securities exchange or market or trading or quotation
facility on which the Common Stock is then listed) as soon as possible
thereafter, and (iii) provide to the Purchaser evidence of such listing, and the
Company shall maintain the listing of its Common Stock thereon. If the number of
Underlying Shares issuable upon conversion in full of the then outstanding
Shares, as payment of dividends thereon, and upon exercise of the then
unexercised portion of the Warrant exceeds 85% of the number of Underlying
Shares previously listed on account thereof with NASDAQ (and any such other
required exchanges), then the Company shall take the necessary actions to
immediately list a number of Underlying Shares as equals no less than the then
Current Required Minimum.

          (b)  The Company shall maintain a reserve of shares of Common Stock
for issuance upon conversion of the Shares and for payment of dividends
thereupon in shares of Common Stock and upon exercise in full of the Warrant in
accordance with this Agreement, the Certificate of Designation and the Warrant,
respectively, in such amount as may be required to fulfill its obligations in
full under the Transaction Documents, which reserve shall equal no less than the
then Current Required Minimum.

     3.7  Conversion and Exercise Procedures.  The Transfer Agent Instructions,
          ----------------------------------                                   
Conversion Notice (as defined in Exhibit A) and Notice of Exercise under the
                                 ----------                                 
Warrant set forth the totality of the procedures with respect to the conversion
of the Shares and exercise of the Warrant, including the form of legal opinion,
if necessary, that shall be rendered to the Company's transfer agent and such
other information and instructions as may be reasonably necessary to enable the
Purchaser to convert its Shares and exercise the Warrant as contemplated in the
Certificate of Designation and the Warrant (as applicable).

      3.8 Notice of Breaches.  Each of the Company and the Purchaser shall give
          ------------------                                                   
prompt written notice to the other of any breach by it of any representation,
warranty or other agreement contained in any Transaction Document, as well as
any events or occurrences arising after the date hereof which would reasonably
be likely to cause any representation or warranty or other agreement of such
party, as the case may be, contained therein to be incorrect or breached as of
the Closing Date.  However, no disclosure by either party pursuant to this
Section shall be deemed to cure any breach of any representation, warranty or
other agreement contained in any Transaction Document.

      3.9 Conversion and Exercise Obligations of the Company.  The Company shall
          --------------------------------------------------

Underlying Shares in accordance with the respective terms, conditions and time

Company shall not, directly or indirectly, without the prior written consent of
the Purchaser, offer, sell, grant any option to purchase, or otherwise dispose

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

receipt of the Subsequent Placement Notice of its willingness to cause the

completion of mutually acceptable documentation, financing to the Company on
substantially the terms set forth in the Subsequent Placement Notice. If the

negotiations within such time period, the Company may effect the Subsequent
Placement substantially upon the terms and to the Persons (or Affiliates of such
Persons) set forth in the Subsequent Placement Notice; provided, that the

first refusal held by the holders of the Company's Series A Convertible
Preferred Stock, as such rights exist on the Closing Date.

Securities" (as such term is defined in the Registration Rights Agreement) to be

same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart.  In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and

                                     -18-

binding obligation of the party executing (or on whose behalf such signature is

otherwise make any such public statement, filings or other communications

shall provide the other party with prior notice of such public statement, filing
or other communication.  Notwithstanding the foregoing, the Company shall not

Purchaser in any filing with the Commission, or any regulatory agency, trading

Agreement shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall not
in any way be affecting or impaired thereby and the parties will attempt to
agree upon a valid and enforceable provision which shall be a reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

          4.13  Remedies.  In addition to being entitled to exercise all rights 
                --------                                                
provided herein or granted by law, including recovery of damages, the Purchaser
will be entitled to specific performance of the obligations of the Company under
the Transaction Documents. Each of the Company and the Purchaser agree that
monetary damages may not be adequate compensation for any loss incurred by
reason of any breach of its obligations described in the foregoing sentence and
hereby agrees to waive in any action for specific performance of any such
obligation the defense that a remedy at law would be adequate.

                                  LITIGATION

1.   On June 11, 1996, a complaint was filed in the United States District Court
for the District of Massachusetts by named plaintiff RBI, an Alaskan limited 
partnership, against the Company, Andrew Najda and Stanley W. Bialek (the 
"Selling Stockholders") and the managing underwriters of the Company's initial 
public offering, Robertson, Stephens & Company, Cowen & Company and Unterberg 
Harris (the "Managing Underwriters"). On or about July 17, 1996, a complaint was
filed in the United States District Court for the District of Massachusetts by 
named plaintiff John Foley against the Company, each member of the Company's 
Board of Directors, (Andrew Najda, Stanley W. Bialek, Gill Cogan, Dr. Paul R. 
Low, Dr. Fouad H. Nader and William H. Thalheimer), Kevin M. Hanks, former Chief
Financial Officer and Treasurer of the Company, and the Managing Underwriters. 
On or about October 16, 1996, an additional complaint was filed in the United 
States District Court for the District of Massachusetts by named plaintiff 
Robert Schoenhofer against the Company, each member of the Company's Board of 
Directors, Mr. Hanks, and the Managing Underwriters. Each of the plaintiffs 
purports to represent a class of purchasers of the Common Stock of the Company 
between and including May 26, 1995 through January 31, 1996. Each complaint 
alleges that the named defendants violated the Securities Act of 1933, as 
amended, and the Securities Exchange Act of 1934, as amended, by, among other 
things, issuing to the investing public false and misleading statements 
regarding the Company's business, products, sales and earnings during the class
period in question. The plaintiffs seek unspecified damages, interest, costs and
fees. By order of the District Court, these actions have been consolidated into
a single action. It is possible that other claims may be made against the
Company or that there may be other consequences from the lawsuits. The
defendants deny any liability, believe they have meritorious defenses, and
intend to vigorously defend these and any similar lawsuits that may be filed,
although the ultimate outcome of these matters cannot yet be determined. If the
lawsuits are not resolved satisfactorily for the Company, there could be a
material adverse effect on the Company's future financial condition and results
of operations and, accordingly, income (loss). The Company does not believe that
the ultimate liability, if any, is estimable or probable, and therefore no
provision for any liability that may result from the actions has been recognized
in the Company's consolidated financial statements.

2.   Finnegan, Henderson, Farabow, Garrett & Dunner, L.L.P has sent the Company 
a letter, dated March 17, 1998, that alleges that the use of the Company's 
monitors with certain on-screen displays infringes upon the patents referenced 
therein.

3.   The Company has received demand letters from Micron, Dell, and Unisys in 
connection with a countersuit filed by Hakan Lans against Micron which has filed
a complaint for declaratory judgment of patent, invalidity and non-infringement 
against Hakan Lans. A motion to amend the complaint in the countersuit has been 
filed by counsel to Hakan Lans to include the Company as an additional 
defendant.

                            OTHER LOAN ARRANGEMENTS

     On March 31, 1999, contingent upon the closing of this financing, the 
Company established a revolving line of credit with BankBoston, N.A. from which 
the Company paid down and replaced a borrowing facility with Marine Midland Bank
("Marine Midland") which, at the time, was subject to a forbearance agreement 
pursuant to which Marine Midland waived certain default provisions relating to 
the borrowing facility up to and through March 31, 1999.

                 NOTICE OF LISTING OR MAINTAINANCE REQUIREMENTS

The Company received a letter from David A. Donahoe, Jr., counsel to NASDAQ 
dated June 29, 1998 with regard to the delisting of the Company on the NASDAQ 
National Market System with respect to meeting net tangible assets measurements 
required by the NASD. The Company responded to counsel to NASDAQ with 
information that Silicon Graphics, Inc. converted its secured subordinated 
convertible promissory notes in the aggregate amount of $9 million plus accrued 
interest into 3,350,894 shares of Series A Preferred Stock (the "Series A 
Preferred Stock"). Due to the conversion of Silicon Graphic, Inc.'s secured 
subordinated convertible promissory notes into Series A Preferred Stock, the 
Company was not delisted.

                            Term of Preferred Stock

          Section 1.     Designation, Amount and Par Value.  The series of 
                         ---------------------------------
preferred stock shall be designated as 4% Series B Convertible Preferred Stock 
(the "Preferred Stock") and the number of shares so designated shall be 300 
      ---------------
(which shall not be subject to increase without the consent of the holders of 
the Preferred Stock (each, a "Holder" and collectively, the "Holders")). Each
                              ------                         -------
share of Preferred Stock shall have a par value of $.01 and a stated value of 
$10,000 (the "Stated Value").
              ------------

          Section 2.     Dividends.
                         ---------

          (a)  Holders shall be entitled to receive, when and as declared by the
Board of Directors out of funds legally available therefor, and the Company 
shall pay, cumulative dividends at the rate per share (as a percentage of the 
Stated Value per share) of 4% per annum, payable, subject to the provisions of 
this Section 2(a), on a quarterly basis on March 31, June 30, September 30 and 
December 31 of each year while such share is outstanding (each a "Dividend 
                                                                  --------
Payment Date") and on each Conversion Date (as defined herein) for such share, 
- ------------
commencing on the earlier to occur of the Conversion Date for such share and 
June 30, 1999, in cash or shares of Common Stock (as defined in Section 8). 
Subject to the terms and conditions herein, the decision whether to pay 
dividends hereunder in Common Stock or cash shall be at the discretion of the 
Company. Dividends on the Preferred Stock shall be calculated on the basis of a 
360-day year, shall accrue daily commencing on the Original Issue Date (as 
defined in Section 8), and shall be deemed to accrue from such date whether or 
not earned or declared and whether or not there are profits, surplus or other 
funds of the Company legally available for the payment of dividends, unless the 
Company provides the Holder with an unqualified legal opinion of its outside 
counsel (both of which legal opinion and counsel are acceptable to the Holder) 
that the accrual of any such dividend (as opposed to payment) is not permitted 
at such time under the General Corporation Law of the State of Delaware. A party
that holds shares of Preferred Stock on the record date with respect to a 
Dividend Payment Date will be entitled to receive such dividend payment and any 
other accrued and unpaid dividends which accrued prior to such Dividend Payment 
Date, without regard to any sale or disposition of such Preferred Stock 
subsequent to the applicable record date. Except as otherwise provided herein, 
if at any time the Company pays less than the total amount of dividends then
accrued on account of the Preferred Stock, such payment shall be distributed
ratably among the Holders based upon the number of shares of Preferred Stock
held by each Holder. If the Company is permitted hereunder to pay dividends in
shares of Common Stock, then the number of shares of Common Stock issuable on
account of such dividend shall equal the cash amount of such dividend on either
the Dividend Payment Date or the Conversion Date, as applicable, divided by the
Conversion Price (as defined herein) on such date. Any dividends to be paid in
cash hereunder that are not paid within three (3) Trading Days (as defined in
Section 8) following a Conversion Date or Dividend Payment Date, as applicable,
shall continue to accrue and shall entail a late fee, which must be paid in
cash, at the rate of 18% per annum (such fees to accrue daily, from the date
such dividend is due hereunder through and including the date of payment). The
Company shall provide the Holders written notice of its intention to pay
dividends in cash or shares of Common Stock not less than ten (10) days prior to
any Dividend Payment Date for so long as shares of Preferred Stock are
outstanding (the Company may indicate in such notice the maximum amount of cash
dividends that it intends to pay during such period). Failure to timely provide
such notice shall be deemed an election by the Company to pay dividends for such
period in shares of Common Stock pursuant to the terms hereof.

          (b)  Notwithstanding anything to the contrary contained herein, the 
Company may not
<PAGE>
 
issue shares of Common Stock in payment of dividends on the Preferred Stock (and
must deliver cash in respect thereof, subject to the provisions of Section 2(a)
with respect to applicable law) if:

               (i)    the number of shares of Common Stock at the time 
authorized, unissued and unreserved for all purposes is insufficient to pay such
dividends in shares of Common Stock;

               (ii)   after the Dividend Effectiveness Date (as defined in 
Section 8), such shares (x) are not registered for resale pursuant to an 
effective Underlying Securities Registration Statement (as defined in Section 
8), or (y) may not be sold without volume restrictions pursuant to Rule 144 
promulgated under the Securities Act (as defined in Section 8), as determined by
counsel to the Company pursuant to a written opinion letter, addressed to the 
Company's transfer agent in the form and substance acceptable to the applicable 
Holder and such transfer agent (if the Company is permitted and elects to pay 
dividends in shares of Common Stock under this clause (ii) prior to the Dividend
Effectiveness Date and thereafter an Underlying Securities Registration 
Statement shall be declared effective by the Commission (as defined in Section 
8), the Company shall, within three (3) Trading Days after the date of such 
declaration of effectiveness, exchange such shares for shares of Common Stock 
that are free of restrictive legends of any kind);

               (iii)  the Company has failed to timely satisfy its conversion 
obligations hereunder; or     
          
               (iv)   the issuance of such shares would result in a violation of
Section 5(a)(iii) or the rules of the Nasdaq Stock Market, Inc. or any other 
rules and regulations governing any Subsequent Market (as defined in Section 8) 
on which the Common Stock is then listed or quoted for trading.

          (c)  So long as any Preferred Stock shall remain outstanding, neither 
the Company nor any subsidiary thereof shall redeem, purchase or otherwise 
acquire directly or indirectly any Junior Securities (as defined in Section 8), 
nor shall the Company directly or indirectly pay or declare any dividend or make
any distribution (other than a dividend or distribution described in Section 5 
or dividends due and paid in the ordinary course on preferred stock of the 
Company at such times when the Company is in compliance with its payment and 
other obligations hereunder) upon, nor shall any distribution be made in respect
of, any Junior Securities, nor shall any monies be set aside for or applied to 
the purchase or redemption (through a sinking fund or otherwise) of any Junior 
Securities or shares pari passu with the Preferred Stock.

          Section 3.     Voting Rights.  Except as otherwise provided herein and
                         -------------
as otherwise required by law, the Preferred Stock shall have no voting rights. 
However, so long as any shares of Preferred Stock are outstanding, the Company 
shall not, without the affirmative vote of the Holders of a majority of the 
shares of the Preferred Stock then outstanding, (a) alter or change adversely 
the powers, preferences or rights given to the Preferred Stock or alter or amend
this Certificate of Designation, (b) authorize or create any class of stock 
ranking as to dividends or distribution of assets upon a Liquidation (as defined
in Section 4) senior to or otherwise pari passu with the Preferred Stock, (c) 
amend its certificate of incorporation or other charter documents so as to 
affect adversely any rights of the Holders, (d) increase the authorized number 
of shares of Preferred Stock, or (e) enter into any agreement with respect to 
the foregoing.

          Section 4.     Liquidation.  Upon any liquidation, dissolution or 
                         -----------
winding-up of the Company, whether voluntary or involuntary (a "Liquidation"), 
                                                                -----------
the Holders shall be entitled, subject to the rights of the holders of the 
Company's Series A Convertible Preferred Stock to receive out of the assets of 
the Company, whether such assets are capital or surplus, for each share of 
Preferred Stock an

                                       2
<PAGE>
 
amount equal to the Stated Value plus all due but unpaid dividends per share, 
whether declared or not, before any distribution or payment shall be made to the
holders of any Junior Securities, and if the assets of the Company shall be 
insufficient to pay in full such amounts, then the entire assets to be 
distributed to the Holders shall be distributed among the Holders ratably in 
accordance with the respective amounts that would be payable on such shares if 
all amounts payable thereon were paid in full. A sale, conveyance or 
disposition of all or substantially all of the assets of the Company or the 
effectuation by the Company of a transaction or series of related transactions
in which more than 50% of the voting power of the Company is disposed of, or a
consolidation or merger of the Company with or into any other company or
companies shall not be treated as a Liquidation, but instead shall be subject to
the provisions of Section 5. The Company shall mail written notice of any such
Liquidation, not less than 45 days prior to the payment date stated therein, to
each record Holder.

          Section 5.      Conversion.
                          ----------

          (a)(i) Conversions at Option of Holder. Each share of Preferred Stock 
                 -------------------------------
shall be convertible into shares of Common Stock (subject to the limitations set
forth in Section 5(a)(iii)), at the Conversion Ratio (as defined in Section 8), 
at the option of the Holder at any time and from time to time from and after 
July 28, 1999 (the "Initial Conversion Date"); provided, that, (A) on and after 
                    -----------------------    --------
the Initial Conversion Date, a Holder shall only be entitled to convert up to
25% of the number of shares of Preferred Stock issued to it on the Original
Issue Date, (B) on and after the first month anniversary of the Initial
Conversion Date, a Holder shall only be entitled to convert up to 50% of the
number of shares of Preferred Stock issued to it on the Original Issue Date, on
a cumulative basis, (C) on and after the second month anniversary of the Initial
Conversion Date, a Holder shall only be entitled to convert up to 75% of the
number of shares of Preferred Stock issued to it on the Original Issue Date, on
a cumulative basis and (D) on and after the third month anniversary of the
Initial Conversion Date, a Holder shall be entitled to convert all of the shares
of Preferred Stock originally issued to it on the Original Issue Date. Holders
shall effect conversions by surrendering the certificate or certificates
representing the shares of Preferred Stock to be converted to the Compnay,
together with the form of conversion notice attached hereto as Exhibit A (a
                                                               ---------  
"Conversion Notice"). Each Conversion Notice shall specify the number of shares
 -----------------
of Preferred Stock to be converted and the date on which such conversion is to
be effected, which date may not be prior to the date the Holder delivers such
Conversion Notice by fascimile (the "Conversion Date"). If no Conversion Date
                                      ---------------
is specified in a Conversion Notice, the Conversion Date shall be the date that
the Conversion Notice is deemed delivered hereunder. If the Holder is converting
less than all shares of Preferred Stock represented by the certificate or 
certificates tendered by the Holder with the Conversion Notice, or if a 
conversion hereunder cannot be effected in full for any reason, the Company 
shall promptly deliver to such Holder (in the manner and within the time set 
forth in Section 5(b)) a certificate representing the number of shares of 
Preferred Stock as have not been converted.

          (ii) Automatic Conversion. Subject to the provisions in this 
               --------------------
paragraph, all outstanding shares of Preferred Stock for which conversion
notices have not previously been received or for which redemption has not been
made or required hereunder shall be automatically converted on the third
anniversary of the Original Issue Date for such shares. The conversion
contemplated by this paragraph shall not occur at such time as (a) (1) an
Underlying Securities Registration Statement is not then effective or (2) the
Holder is not permitted to resell Underlying Shares (as defined in Section 8)
pursuant to Rule 144(k) promulgated under the Securities Act, without volume
restrictions, as evidenced by an opinion letter of counsel acceptable to the
Holder and the transfer agent for the Common Stock; (b) there are not sufficient
shares of Common Stock authorized and reserved for issuance upon such
conversion; or (c) the Company is then in default of its covenants and
obligations hereunder or under the Purchase Agreement or Registration Rights
Agreement. Notwithstanding the foregoing, the three-year period for conversion
under this Section shall be extended (on a day-for-day

                                       3
<PAGE>
 
basis) for any Trading Days after the date that the Commission declares
effective an Underlying Securities Registration Statement that the Purchaser is
unable to resell Underlying Shares under an Underlying Securities Registration
Statement due to (a) the Common Stock not being listed for trading on the Nasdaq
National Market (the "NASDAQ") or any Subsequent Market, (b) the failure of such
                      ------
Underlying Securities Registration Statement to remain effective during the
Effectiveness Period (as defined in the Registration Rights Agreement) as to all
Underlying Shares, or (c) the suspension of the Holder's ability to resell
Underlying Shares thereunder. The provisions of Sections 5(a)(iii)(A)(1) and (2)
shall not apply to any automatic conversion pursuant to this Section 5(a)(ii).

               (iii) Certain Conversion Restrictions.
                     -------------------------------

               (A)(1) A Holder may not convert shares of Preferred Stock or 
receive shares of Common Stock as payment of dividends hereunder to the extent 
such conversion or receipt of such dividend payment would result in the Holder 
beneficially owning (as determined in accordance with Section 13(d) of the 
Exchange Act and the rules thereunder) in excess of 4.999% of the then issued
and outstanding shares of Common Stock, including shares insuable upon
conversion of dividends on, the shares of Preferred Stock held by such Holder
after application of this Section. The Holder shall have the sole authority and
obligation to determine whether the restriction contained in this Section
applies and to the extent that the Holder determines that the limitation
contained in this Section applies, the determination of which shares of
Preferred Stock are convertible shall be in the sole discretion of the Holder.
The provisions of this Section may be waived by a Holder (but only as to itself
and not to any other Holder) upon not less than 75 days prior notice to the
Company, Other Holders shall be unaffected by any such waiver.

                  (2)  A Holder may not convert shares of Preferred Stock or
received shares of Common Stock as payment of dividends hereunder to the extent
such conversion or receipt of such dividend payment would result in the Holder
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act (as defined in Section 8) and the rules thereunder) in excess of
9.999% of the then issued and outstanding shares of Common Stock, including
shares issuable upon conversion of, and payment of dividends on, the shares of
Preferred Stock held by such Holder after application of this Section. The
Holder shall have the sole authority and obligation to determine whether the
restriction contained in this Section applies and to the extent that the Holder
determines that the limitation contained in this Section applies, the
determination of which shares of Preferred Stock are convertible shall be in the
sole discretion of the Holder. The provisions of this Section may be waived by a
Holder (but only as to itself and not to any other Holder) upon not less than 75
days prior notice to the Company. Other Holders shall be unaffected by any such
waiver.

               (B)  Notwithstanding anything to the contrary set forth herein, 
the Company shall not be obligated to issue in excess of 1,883,237 shares of 
Common Stock upon conversion of Preferred Stock and payment of dividends 
hereunder, which number of shares shall be subject to adjustment pursuant to 
Sections 5(c)(ii), (iii), and (v) (such number of shares, the "Issuable 
                                                               --------  
Maximum"). The Issuable Maximum equals 19.99% of the number of shares of Common 
- -------
Stock outstanding immediately prior to the Closing. Shares of Common Stock 
issued in respect of liquidated damages hereunder shall not count towards the 
1,883,237 share limit set forth in this paragraph and shall be paid in cash as 
provided herein unless otherwise agreed to by the Holders. If on any Conversion 
Date (A) the Conversion Price then in effect is such that the aggregate number 
of shares of Common Stock that would then be issuable upon conversion in full of
all then outstanding shares of Preferred Stock and as payment of dividends 
thereon in shares of Common Stock, together with any shares of Common Stock 
previously issued upon conversion of shares of Preferred Stock and as payment of
dividends thereon, would equal or exceed the Issuable Maximum, and (B) the 
Company shall not have previously obtained the vote of 
 
                                       4

shareholders (the "Shareholder Approval"), if any, as may be required by the 
                   --------------------
applicable rules and regulations of the Nasdaq Stock Market or other exchange or
market on which the Common Stock is then listed or quoted for trading to approve
the issuance of shares of Common Stock in excess of the Issuable Maximum 
pursuant to the terms hereof, then the Company shall issue to the Holder so 
requesting a conversion a number of shares of Common Stock equal to its pro-rata
share of the Issuable Maximum (determined by reference to the number of shares 
of Preferred Stock issued to all Holders on the Original Issue Date) and, with 
respect to the remainder of the aggregate Stated Value of the shares of 
Preferred Stock then held by such Holder for which a conversion in accordance 
with the Conversion Price would result in an issuance of shares of Common Stock 
in excess of the Issuable Maximum (the "Excess Stated Value"), the converting 
                                        -------------------
Holder shall have the option to require the Company to either (1) obtain the 
Shareholder Approval applicable to such issuance as soon as is possible, but in
any event not later than the 75th day after such request, or (2) pay cash to the
converting Holder in an amount equal to the Mandatory Redemption Amount (as
defined in Section 8) for the Excess Stated Value. If the Company fails to pay
the Mandatory Redemption Amount in full pursuant to this Section within seven
(7) days after the date payable, the Company will pay interest thereon at a rate
of 18% per annum to the converting Holder, accruing daily from the Conversion
Date until such amount, plus all such interest thereon, is paid in full. If the
Company has been requested by the Holders to obtain, and fails to obtain, the
Shareholder Approval by the 75/th/ day after such request, then the Holders
shall have the right to require the Company to perform under, at the sole option
of such Holder, clause (3) of this Section 5(a)(iii)(B). The Company and the
Holders understand and agree that shares of Common Stock issued to and then held
by Holders as a result of conversions of Preferred Stock and as payment of
dividends thereon shall not be entitled to cast votes on any resolution to
obtain Shareholder Approval pursuant hereto.

          (b)(i) Not later than three (3) Trading Days after any Conversion
Date, the Company will deliver to the Holder (i) a certificate or certificates
which shall be free of restrictive legends and trading restrictions (other than
those required by Section 3.1(b) of the Purchase Agreement) representing the
number of shares of Common Stock being acquired upon the conversion of shares of
Preferred Stock (subject to the limitations set forth in Section 5(a)(iii)
hereof), (ii) one or more certificates representing the number of shares of
Preferred Stock not converted, (iii) a bank check in the amount of accrued and
unpaid dividends (if the Company has elected to pay accrued dividends in cash),
and (iv) if the Company has elected and is permitted hereunder to pay accrued
dividends in shares of Common Stock, certificates, which shall be free of
restrictive legends and trading restrictions (other than those required by
Section 3.1(b) of the Purchase Agreement), representing such shares of Common
Stock, provided, however, that the Company shall not be obligated to issue 
       --------  -------
certificates evidencing the shares of Common Stock issuable upon conversion of
any shares of Preferred Stock until certificates evidencing such shares of
Preferred Stock are delivered for conversion to the Company, or the Holder of
such Preferred Stock notifies the Company that such certificates have been lost,
stolen or destroyed and provides a bond (or other adequate security) reasonably
satisfactory to the Company to indemnify the Company from any loss incurred by
it in connection therewith. The Company shall, upon request of the Holder, if
available, use its best efforts to deliver any certificate or certificates
required to be delivered by the Company under this Section electronically
through the Depository Trust Corporation or another established clearing
corporation performing similar functions. If in the case of any Conversion
Notice such certificate or certificates, including for purposes hereof, any
shares of Common Stock to be issued on the Conversion Date on account of accrued
but unpaid dividends hereunder, are not delivered to or as directed by the
applicable Holder by the third (3/rd/) Trading Day after the Conversion Date,
the Holder shall be entitled by written notice of the Company at any time on or
before its receipt of such certificate or certificates thereafter, to rescind
such conversion, in which event the Company shall immediately return the
certificates representing the shares of Preferred Stock tendered for conversion.

               (ii) If the Company fails to deliver to the Holder such
certificate or certificates pursuant to Section 5(b)(i), including for purposes
hereof, any shares of Common Stock to be issued on the Conversion Date on
account of accrued but unpaid dividends hereunder, by the third (3rd) Trading
Day after the Conversion Date, the Company shall pay to such Holder, in cash, as
liquidated damages and not as a penalty, $5,000 for each Trading Day after such
third (3rd) Trading Day until such certificates are delivered. Nothing herein
shall limit a Holder's right to pursue actual damages for the Company's failure
to deliver certificates representing shares of Common Stock upon conversion
within the period specified herein and such Holder shall have the right to
pursue all remedies available to it at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief. The
exercise of any such rights shall not prohibit the Holders from seeking to
enforce damages pursuant to any other Section hereof or under applicable law.
Further, if the Company shall not have delivered any cash due in respect of
conversions of Preferred Stock or as payment of dividends thereon by the third
(3rd) Trading Day after the Conversion Date, the Holder may, by notice to the
Company, require the Company to issue shares of Common Stock pursuant to Section
5(c), except that for such purpose the Conversion Price applicable thereto shall
be the lesser of the Conversion Price on the Conversion Date and the Conversion
Price on the date of such Holder demand. Any such shares will be subject to the
provision of this Section.

               (iii) In addition to any other rights available to the Holder, if
the Company fails to deliver to the Holder such certificate or certificates
pursuant to Section 5(b)(i), including for purposes hereof, any shares of Common
Stock to be issued on the Conversion Date on account of accrued but unpaid
dividends hereunder, by the third (3rd) Trading Day after the Conversion Date,
and if after such third (3rd) Trading Day the Holder purchases (in an open
market transaction or otherwise) Common Stock to deliver in satisfaction of a
sale by such Holder of the Underlying Shares which the Holder was entitled to
receive upon such conversion (a "Buy-In"), then the Company shall (A) pay in
                                 -------       
cash to the Holder (in addition to any remedies available to or elected by the
Holder) the amount by which (x) the Holder's total purchase price (including
brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the
product of (1) the aggregate number of shares of Common Stock so purchased
exceeds (y) the product of (1) the aggregate number of shares of Common Stock
that such Holder was entitled to receive from the conversion at issue multiplied
by (2) the market price of the Common Stock at the time of the sale giving rise
to such purchase obligation and (B) at the option of the Holder, either return
the shares of Preferred Stock for which such conversion was not honored or
deliver to such Holder the number of shares of Common Stock that would have been
issued had the Company timely complied with its conversion and delivery
obligations under Section 5(b)(i). For example, if the Holder purchases Common
Stock having a total purchase price of $11,000 to cover a Buy-In with respect to
an attempted conversion of shares of Preferred Stock with respect to which the
market price of the Underlying Shares on the date of Conversion totaled $10,000,
under clause (A) of the immediately preceding sentence the Company shall be
required to pay the Holder $1,000. The Holder shall provide the Company written
notice indicating the amounts payable to the Holder in respect of the Buy-In.
Notwithstanding anything contained herein to the contrary, if a Holder requires
the Company to make payment in respect of a Buy-In for the failure to timely
deliver certificates hereunder and the Company timely pays in full such payment,
the Company shall not be required to pay such Holder liquidated damages under
Section 5(b)(ii) in respect of the certificates resulting in such Buy-In.

        (c)(i) The conversion price for each share of Preferred Stock (the 
"Conversion Price") in effect on any Conversion Date shall be the lesser of (a) 
 ----------------
$4,2703 (the "Fixed Conversion Price") or (b) 88% of the average of the ten (10)
              ----------------------
lowest Per Share Market Values during the thirty (30) Trading Days immediately 
preceding the applicable Conversion Date (which, at the Holder's option, may 
include Trading Days prior to the Initial Conversion Date), provided, that such 
                                                            --------
thirty (30) Trading Day period shall be extended for the number of Trading Days,
if any, during such period in which (A) trading in the Common Stock is suspended
from the NASDAQ or a Subsequent Market on which it is listed for trading

                                       6
<PAGE>
 
prior to such suspension, or (B) after the date declared effective by the 
Commission, the Underlying Securities Registration Statement is now effective, 
or (C) after the date declared effective by the Commission, the Prospectus 
included in the Underlying Securities Registration Statement may not be used by 
the Holder for the resale of Underlying Shares.

          If (a) the Underlying Securities Registration Statement is not filed 
on or prior to the Filing Date (if the Company files such Underlying Securities 
Registration Statement without affording the Holder the opportunity to review 
and comment on the same as required by Section 3(a) of the Registration Rights 
Agreement, the Company shall not be deemed to have satisfied this clause (a)), 
or (b) the Company fails to file with the Commission a request for acceleration 
in accordance with Rule 12d1-2 promulgated under the Securities Exchange Act of 
1934, as amended, within five (5) days of the date that the Company is notified 
(orally or in writing, whichever is earlier) by the Commission that an 
Underlying Securities Registration Statement will not be "reviewed," or not 
subject to further review or comment, or (c) the Underlying Securities 
Registration Statement is not declared effective by the Commission on or prior 
to the Effectiveness Date, or (d) such Underlying Securities Registration 
Statement is filed with and declared effective by the Commission but thereafter 
ceases to be effective as to all Registrable Securities (as defined in the 
Registration Rights Agreement) at any time prior to the expiration of the 
Effectiveness Period without being succeeded within ten (10) days by a 
subsequent Underlying Securities Registration Statement filed with and declared
effective by the Commission, or (e) trading in the Common Stock shall be 
suspended from the NASDAQ or a Subsequent Market for more than three (3) 
Business Days (which need not be consecutive days), (f) the conversion rights of
the Holders are suspended for any reason or (g) an amendment to the Underlying 
Securities Registration Statement is not filed by the Company with the 
Commission within ten (10) days of the Commission's notifying the Company that 
such amendment is required in order for the Underlying Securities Registration 
Statement to be declared effective (if the Company files such amendment 
without affording the Holder the opportunity to review and comment on the same 
as required by Section 3(a) of the Registration Rights Agreement, the Company 
shall not be deemed to have satisfied this clause (g)) (any such failure or 
breach being referred to as an "Event" and for purposes of clauses (a), (c), (f)
                                -----
the date on which such Event occurs, or for purposes of clause (b) the date on 
which such five (5) day period is exceeded, or for purposes of clauses (d) and 
(g) the date which such 10 day-period is exceeded, or for purposes of clause (e)
the date on which such three (3) Business Day-period is exceeded, being referred
to as "Event Date"), then, on the Event Date and on each monthly anniversary
       ----------
thereof until such time as the applicable Event is cured, the Company shall pay 
to the Holder 2.5% of the aggregate Stated Value of all of the shares of 
Preferred Stock purchased by such Holder under the Purchase Agreement in cash, 
as liquidated damages and not as a penalty. The provisions of this Section are 
not exclusive and shall in no way limit the Company's obligations hereunder.

          (ii) If the Company, at any time while any shares of Preferred Stock 
are outstanding, shall (a) pay a stock dividend or otherwise make a distribution
or distributions of shares of its Junior Securities or pari passu securities 
payable in shares of Common Stock, (b) subdivide outstanding shares of Common 
Stock into a larger number of shares, (c) combine outstanding shares of Common 
Stock into a smaller number of shares, or (d) issue by reclassification and 
exchange of the Common Stock any shares of capital stock of the Company, then 
the Fixed Conversion Price shall be multiplied by a fraction of which the 
numerator shall be the number of shares of Common Stock outstanding before such 
event and of which the denominator shall be the number of shares of Common Stock
outstanding after such event. Any adjustment made pursuant to this Section 
5(c)(ii) 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, combination or re-classification.

                                       7
<PAGE>
 
               (iii)     If the Company, at any time while any shares of
Preferred Stock are outstanding, shall issue rights, warrants or options to all
holders of Common Stock entitling them to subscribe for or purchase shares of
Common Stock at a price per share less than the Per Share Market Value at the
record date mentioned below, then the Fixed Conversion Price shall be multiplied
by a fraction, the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to the issuance of such rights, warrants or
options, plus the number of shares of Common Stock which the aggregate offering
price of the total number of shares so offered would purchase at such Per Share
Market Value, and the denominator of which shall be the sum of the number of
shares of Common Stock outstanding immediately prior to such issuance plus the
number of shares of Common Stock offered for subscription or purchase. Such
adjustment shall be made whenever such rights or warrants are issued, and shall
become effective immediately after the record date for the determination of
stockholders entitled to receive such rights or warrants. However, upon the
expiration of any right, warrant or option to purchase shares of Common Stock
the issuance of which resulted in an adjustment in the Conversion Price pursuant
to this Section 5(c)(iii), if any such right, warrant or option shall expire and
shall not have been exercised, the Conversion Price shall immediately upon such
expiration shall be recomputed and effective immediately upon such expiration
shall be increased to the price which it would have been (but reflecting any
other adjustments in the Conversion Price made pursuant to the provisions of
this Section 5 upon the issuance of other rights or warrants) had the adjustment
of the Conversion Price made upon the issuance of such rights, warrants, or
options been made on the basis of offering for subscription or purchase only
that number of shares of Common Stock actually purchased upon the exercise of
such rights, warrants or options actually exercised.

               (iv)      If the Company or any subsidiary thereof, as applicable
with respect to Common Stock Equivalents (as defined below), at any time while 
any shares of Preferred Stock are outstanding, shall issue shares of Common 
Stock or rights, warrants, options or other securities or debt that is 
convertible into or exchangeable for shares of Common Stock ("Common Stock 
                                                              ------------
Equivalents"), 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 Original Issue Date, 
entitling any Person to acquire shares of Common Stock at a price per share less
than the Conversion Price, then the Conversion Price shall be multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior to the issuance of such Common Stock or such
Common Stock Equivalents plus the number of shares of Common Stock which the
offering price for such shares of Common Stock or Common Stock Equivalents would
purchase at the Conversion Price, and the denominator of which shall be the sum
of the number of shares of Common Stock outstanding immediately prior to such
issuance plus the number of shares of Common Stock so issued or issuable,
provided, that for purposes hereof, all shares of Common Stock that are issuable
- --------
upon conversion, exercise or exchange of Common Stock Equivalents shall be
deemed outstanding immediately after the issuance of such Common Stock
Equivalents. Such adjustment shall be made whenever such Common Stock or Common
Stock Equivalents are issued.

               (v)       If the Company, at any time while shares of Preferred 
Stock are outstanding, shall distribute to all holders of Common Stock (and not 
to Holders) evidences of its indebtedness or assets or rights or warrants to 
subscribe for or purchase any security (excluding those referred to in Sections 
5(c)(ii)-(iv) above), then in each such case the Fixed Conversion Price at which
each share of Preferred Stock shall thereafter be convertible shall be 
determined by multiplying the Fixed Conversion 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 Per Share 
Market Value determined as of the record date mentioned above, and of which the 
numerator shall be such Per 

                                       8
<PAGE>
 
Share Market Value on such record date less the then fair market value at such
record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding shares of Common Stock as determined
by the Board of Directors in good faith; provided, however, that in the event of
                                         --------  -------
a distribution exceeding ten percent (10%) of the net assets of the Company, if 
the Holders of a majority in interest of the Preferred Stock dispute such 
valuation, such fair market value shall be determined by a nationally recognized
or major regional investment banking firm or firm of independent certified 
public accountants of recognized standing (which may be the firm that regularly 
examines the financial statements of the Company) (an "Appraiser") selected in 
                                                       ---------
good faith by the Holders of a majority in interest of the shares of Preferred 
Stock then outstanding; and provided, further, that the Company, after receipt 
                            --------  -------
of the determination by such Appraiser shall have the right to select an 
additional Appraiser, in good faith, in which case the fair market value shall 
be equal to the average of the determinations by each such Appraiser. In either 
case the adjustments shall be described in a statement provided to the Holders 
of the portion of assets or evidences of indebtedness so distributed or such 
subscription rights applicable to one share of Common Stock. Such adjustment 
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

                    (vi)    All calculations under this Section 5 shall be made 
to the nearest cent or the nearest 1/100th of a share, as the case may be.

                    (vii)   Whenever the Conversion Price is adjusted pursuant 
to Section 5(o)(ii), (iii), (iv), or (v) the Company shall promptly mail to each
Holder, a notice setting forth the Conversion Price after such adjustment and 
setting forth a brief statement of the facts requiring such adjustment.

                    (viii)  In case of any reclassification of the Common Stock,
or any compulsory share exchange pursuant to which the Common Stock is converted
into other securities, cash or property (other than compulsory share exchanges
which constitute Change of Control Transactions), the Holders of the Preferred
Stock then outstanding shall have the right thereafter to convert such shares
only into the shares of stock and other securities, cash and property receivable
upon or deemed to be held by holders of Common Stock following such
reclassification or share exchange, and the Holders of the Preferred Stock shall
be entitled upon such event to receive such amount of securities, cash or
property as a holder of the number of shares of Common Stock of the Company into
which such shares of Preferred Stock could have been converted immediately prior
to such reclassification or share exchange would have been entitled. This
provision shall similarly apply to successive reclassifications or share
exchanges.

                    (ix)    If (a) the Company shall declare a dividend (or any
other distribution) on the Common Stock, (b) the Company shall declare a special
nonrecurring cash dividend on or a redemption of the Common Stock, (c) the
Company shall authorize the granting to all holders of Common Stock rights or
warrants to subscribe for or purchase any shares of capital stock of any class
or of any rights, (d) the approval of any stockholders of the Company shall be
required in connection with any reclassification of the Common Stock, 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, of any compulsory share
of exchange whereby the Common Stock is converted into other securities, cash or
property, or (e) the Company shall authorize the voluntary or involuntary
dissolution, liquidation or winding up of the affairs of the Company; then the
Company shall cause to be filed at each office or agency maintained for the
purpose of conversion of Preferred Stock, and shall cause to be mailed to the
Holders at their last addresses as they shall appear upon the stock books of the
Company, at least 20 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

                                       9
<PAGE>
 
record is not to be taken, the date as of which the holders of Common Stock of 
record to be 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 Common Stock for 
securities, cash or other property deliverable upon such reclassification, 
consolidation, merger, sale, transfer or share exchange. Holders are entitled to
convert shares of Preferred Stock during the 20-day period commencing the date 
of such notice to the effective date of the event triggering such notice.

          (x)  In case of any (1) merger or consolidated of the Company with or
into another Person that would constitute a Change of Control Transaction, or
(2) sale by the Company of more than one-half of the assets of the Company (on
an as valued basis) in one or a series of related transactions, or (3) tender
or other offer or exchange (whether by the Company or another Person) pursuant
to which holders of Common Stock are permitted to tender or exchange their
shares for other securities, stock, cash or property of the Company or another
Person; then, if a Holder has not exercised its rights of redemption, if any,
under Section 7 hereof, such Holder shall have the right thereafter to (A) if
permitted under Section 7 hereof, exercise its rights of redemption under
Section 7 with respect to such event, (B) convert its shares of Preferred Stock
into the shares of stock and other securities, cash and property receivable upon
or deemed to be held by holders of Common Stock following such merger,
consolidation or sale, and such Holder shall be entitled upon such event or
series of related events to receive such amount of securities, cash and property
as the shares of Common Stock into which such shares of Preferred Stock could
have been converted immediately prior to such merger, consolidation or sales
would have been entitled, (C) in the case of a merger or consolidation, (x)
require the surviving entity to issue shares of convertible preferred stock or
convertible debentures with such aggregate stated value or in such face amount,
as the case may be, equal to the Stated Value of the shares of Preferred Stock
then held by such Holder, plus all accrued and unpaid dividends and other
amounts owing thereon, which newly issued shares of preferred stock or
debentures shall have terms identical (including with respect to conversion) to
the terms of the Preferred Stock (except, in the case of debentures, as may be
required to reflect the differences between debt and equity) and shall be
entitled to all of the rights and privileges of a Holder of Preferred Stock set
forth herein and the agreements pursuant to which the Preferred Stock was issued
(including, without limitation, as such rights relate to the acquisition,
transferability, registration and listing of such shares of stock other
securities issuable upon conversion thereof), and (y) simultaneously with the
issuance of such convertible preferred stock or convertible debentures, shall
have the right to convert such instrument only into shares of stock and other
securities, cash and property receivable upon or deemed to be held by holders of
Common Stock following such merger or consolidation, or (D) in the event of an
exchange or tender offer or other transaction contemplated by clause (3) of this
Section, tender or exchange its shares of Preferred Stock for such securities,
stock, cash and other property receivable upon or deemed to be held by holders
of Common Stock that have tendered or exchanged their shares of Common Stock
following such tender or exchange, and such Holder shall be entitled upon such
exchange or tender to receive such amount of securities, cash and property as
the shares of Common Stock into which shares of Preferred Stock could have been
converted (taking into account all then accrued and unpaid dividends)
immediately prior to such tender or exchange would have been entitled as would
have been issued. In the case of clause (C), the conversion price applicable for
the newly issued shares of convertible preferred stock or convertible debentures
shall be based upon the amount of securities, cash and property that each share
of Common Stock would receive in such transaction, the Conversion Ratio
immediately prior to the effectiveness or closing date for such transaction and
the Conversion Price stated herein. The terms of any such merger, sale,
consolidation, tender or exchange shall include such terms so as to continue to
give the Holders of Preferred Stock the right to receive the securities, cash
and property set forth in this Section upon any conversion or redemption
following such event. This provision shall similarly apply to successive such

                                      10
<PAGE>
 
events.

          (d)  Upon a conversion hereunder the Company shall not be required to
issue stock certificates representing fractions of shares of Common Stock, but
may if otherwise permitted, make a cash payment in respect of any final fraction
of a share based on the Per Share Market Value at such time. If the Company
elects not, or is unable, to make such a cash payment, the Holder of a share of
Preferred Stock shall be entitled to receive, in lieu of the final fraction of a
share, one whole share of Common Stock.

          (e)  The issuance of certificates for Common Stock on conversion of
Preferred Stock and as payment of dividends in shares of Common Stock shall be
made without charge to the Holders thereof for any documentary stamp or similar
taxes that may be payable in respect of the issue or delivery of such
certificate, provided that the Company shall not be required to pay any tax that
may be payable in respect of any transfer involved in the issuance and delivery
of any such certificate upon conversion in a name other than that of the Holder
of such shares of Preferred Stock so converted.

          (f)  Shares of Preferred Stock converted into Common Stock or redeemed
in accordance with the terms hereof shall be canceled and may not be reissued.

      
          (g)  Any and all notices or other communications or deliveries to be
provided by the Holders of the Preferred Stock hereunder, including, without
limitation, any Conversion Notice, shall be in writing and delivered personally,
by facsimile or sent by a nationally recognized overnight courier service,
addressed to the attention of the Chief Financial Officer of the Company at the
facsimile telephone number or address of the principal place of business of the
Company as set forth in the Purchase Agreement. Any and all notices or other
communications or deliveries to be provided by the Company hereunder shall be in
writing and delivered personally, by facsimile or sent by a nationally
recognized overnight courier service, addressed to each Holder at the facsimile
telephone number or address of such Holder appearing on the books of the
Company, or if no such facsimile telephone number or address appears, at the
principal place of business of the Holder. Any notice or other communication or
deliveries hereunder 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), (ii) the date 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) upon receipt, if sent by a nationally recognized overnight courier
service, or (iv) upon actual receipt by the party to whom such notice is
required to be given.

          Section 6.     Optional Redemption.
                         -------------------

          (a)  Subject to the provisions of this Section 6, the Company shall
have the right, exercisable upon five (5) Trading Days' notice (an "Optional
                                                                    --------  
Redemption Notice") to the Holders to redeem all or any portion of the shares of
- -----------------
Preferred Stock which have not previously been redeemed, at a price equal to the
Optional Redemption Price (as defined below); provided, that, in order to be
valid an Optional Redemption Notice must have been delivered either (1) Within
three (3) Trading Days after any 90 consecutive Trading Day period during which
the average Per Share Market Value was less than the Fixed Conversion Price or
(ii) within one Trading Day after the Per Share Market Value for two (2)
consecutive Trading Days was less than $1.60. The Company shall not be entitled
to deliver an Optional Redemption Notice after the Effectiveness Date if: (i)
the number of shares of Common Stock at the time authorized, unissued and
unreserved for all purposes is insufficient to satisfy the Company's

                                      11
<PAGE>
 
conversion obligations of all shares of Preferred Stock then outstanding, or
(ii) the Underlying Shares then outstanding are not registered for resale
pursuant to an effective Underlying Securities Registration Statement, or (iii)
the Common Stock is not then listed for trading on the NASDAQ, on a Subsequent
Market or the OTC Bulletin Board. The entire Optional Redemption Price shall be
paid in cash. A Holder may convert (and the Company shall honor such conversions
in accordance with the terms hereof) up to 25% of its shares of Preferred Stock
subject to an Optional Redemption Notice given after the Effectiveness Date,
provided that the Conversion Notice for such shares is delivered within 24 hours
following the receipt by such Holder of such an Optional Redemption Notice.

          (b)  Failure by the Company to pay any portion of the Optional 
Redemption Price by the 6th Trading Day following the date of an Optional 
Redemption Notice shall result in the invalidation ab initio if the unpaid 
                                                   --------- 
portion of such optional redemption, and, notwithstanding anything herein to the
contrary, the Company shall thereafter have no further rights to optionally 
redeem any shares of Preferred Stock. In such event, the Company shall, at the 
option of the Holder, either, (i) not later than three (3) Trading Days from 
receipt of Holder's request for such election, return to the Holder all of the 
shares of Preferred Stock for which such Optional Redemption Price has not been 
paid in full (the "Unpaid Redemption Shares") or (ii) convert of all or any 
                   ------------------------
portion of the Unpaid Redemption Shares in which event the Per Share Market 
Value for such shares shall be the lower of the Per Share Market Value 
calculated on the date the Optional Redemption Price was originally due and the 
Per Share Market Value as of the Holder's written demand for conversion. If the 
Holder elects option (ii) above, the Company shall within three (3) Trading Days
of its receipt of such election deliver to the Holder the shares of Common Stock
issuable upon conversion of the Unpaid Redemption Shares subject to such Holder 
conversion demand and otherwise perform its obligations hereunder with respect 
thereto.

          (c)  The "Optional Redemption Price" shall equal the sum of (i) the 
                    -------------------------

     2.   Shelf Registration
          ------------------

          (a) On or prior to the Filing Date, the Company shall prepare and file
with the Commission a "Shelf" Registration Statement covering all Registrable
Securities for an offering to be made on a continuous basis pursuant to Rule
415.  The Registration Statement shall be on Form S-3 (or if the Company is not
then eligible to register for resale the Registrable Securities on Form S-3 such
registration shall be on another appropriate form in accordance herewith, or, in
connection with an Underwritten Offering hereunder, such other form agreed to by
the Company and by the Holders of Registrable Securities). The Company shall use
its best efforts to cause the Registration Statement to be declared effective
under the Securities Act as promptly as possible after the filing thereof, but
in any event prior to the Effectiveness Date, and shall use its best efforts to
keep such Registration Statement continuously effective under the Securities Act
until the date which is three years after the date that such Registration
Statement is declared effective by the Commission or such earlier date when all
Registrable Securities covered by such Registration Statement have been sold or
may be sold without volume restrictions pursuant to Rule 144(k) as determined by

Period"), provided, however, that the Company shall not be deemed to have used
- ------    --------  -------                                                   
its best efforts to keep the Registration Statement effective during the
Effectiveness Period if it voluntarily takes any action that would result in the
Holders not being able to sell the Registrable Securities covered by such
Registration Statement during the Effectiveness Period, unless such action is
required under applicable law or the Company has filed a post-effective
amendment to the Registration Statement and the Commission has not declared it
effective.

          (b) If the Holders of a majority of the Registrable Securities so
elect, an offering of Registrable Securities pursuant to the Registration
Statement may be effected in the form of an Underwritten Offering.  In such
event, and, if the managing underwriters advise the Company and such Holders in
writing that in their opinion the amount of Registrable Securities proposed to
be sold in such Underwritten Offering exceeds the amount of Registrable
Securities which can be sold in such Underwritten Offering, there shall be
included in such Underwritten Offering the amount of such Registrable Securities
which in the opinion of such managing underwriters can be sold, and such amount
shall be allocated pro rata among the Holders proposing to sell Registrable
Securities in such Underwritten Offering.

          (c) If any of the Registrable Securities are to be sold in an
Underwritten Offering, the investment banker in interest that will administer
the offering will be selected by the Holders of a majority of the Registrable
Securities included in such offering subject to the Company's right to approve
such underwriter (which may not be reasonably withheld or delayed).  No Holder
may participate in any Underwritten Offering hereunder unless such Holder (i)
agrees to sell its Registrable Securities on the basis provided in any
underwriting agreements approved by the Persons entitled hereunder to approve
such arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such arrangements.

provisions of the Securities Act and the Exchange Act with respect to the
disposition of all Registrable Securities covered by the Registration Statement

Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

          (c) File additional Registration Statements if the number of
Registrable Securities at any time exceeds the number of shares of Common Stock
then registered in a Registration Statement.  The Company shall have 30 days to
file such additional Registration Statements after its receipt of notice of the
requirement thereof which the Holders may give at any time when the Registrable
Securities exceeds 85% of the number of shares of Common Stock then registered
in a Registration Statement hereunder.  In such event, the Registration
Statement required to be filed by the Company shall include no less than a
number of shares of Common Stock equal to, subject to the limitations on the
Company's obligation to issue shares of Common Stock pursuant to Sections
5(a)(iii)(B) and (C) of the Certificate of Designation, no less than 200% of the
number of shares of Common Stock into which all then outstanding shares of
Preferred Stock are convertible (assuming such conversion occurred on the Filing
Date for such Registration Statement or the date of the filing of the final
acceleration request therefor, whichever  date yields a lower Conversion Price)
and any other Registrable Securities not then registered in a Registration
Statement.

          (d) Notify the Holders of Registrable Securities to be sold, their
Special Counsel and any managing underwriters as promptly as reasonably possible
(and, in the case of (i)(A) below, not less than five (5) days prior to such

later than one (1) Business Day following the day (i)(A) when a Prospectus or
any Prospectus supplement or post-effective amendment to the Registration
Statement is proposed to be filed; (B) when the Commission notifies the Company
whether there will be a "review" of such Registration Statement and whenever the
Commission comments in writing on such Registration Statement (the Company shall
provide true and complete copies thereof and all written responses thereto to
each of the Holders); and (C) with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement (including any underwriting agreement)
contemplated hereby ceases to be true and correct in all material respects; (v)
of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose; and (vi) of the occurrence of any event that makes
any statement made in the Registration Statement or Prospectus or any document
incorporated or deemed to be incorporated therein by reference untrue in any
material respect or that requires any revisions to the Registration Statement,
Prospectus or other documents so that, in the case of the Registration Statement
or the Prospectus, as the case may be, it will not contain any untrue statement
of a material fact or omit to state any

                                      -6-
<PAGE>
 
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

          (e) Use its best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of (i) any order suspending the effectiveness of the
Registration Statement, or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

          (f) If requested by any managing underwriter or the Holders of a
majority in interest of the Registrable Securities to be sold in connection with
an Underwritten Offering, (i) promptly incorporate in a Prospectus supplement or
post-effective amendment to the Registration Statement such information as such
managing underwriters and such Holders reasonably agree should be included
therein, and (ii) make all required filings of such Prospectus supplement or
such post-effective amendment as soon as practicable after the Company has
received notification of the matters to be incorporated in such Prospectus
supplement or post-effective amendment; provided, however, that the Company
                                        --------  -------                  
shall not be required to take any action pursuant to this Section 3(f) that
would, in the opinion of counsel for the Company, violate applicable law or be
materially detrimental to the business prospects of the Company.

          (g) Furnish to each Holder, their Special Counsel and any managing
underwriters, without charge, at least one conformed copy of each Registration
Statement and each amendment thereto, including financial statements and
schedules, all documents incorporated or deemed to be incorporated therein by
reference, and all exhibits to the extent requested by such Person (including
those previously furnished or incorporated by reference) promptly after the
filing of such documents with the Commission.

          (h) Promptly deliver to each Holder, their Special Counsel, and any
underwriters, without charge, as many copies of the Prospectus or Prospectuses
(including each form of prospectus) and each amendment or supplement thereto as

of such Prospectus and each amendment or supplement thereto by each of the
selling Holders and any underwriters in connection with the offering and sale of
the Registrable Securities covered by such Prospectus and any amendment or
supplement thereto.

          (i) Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the selling Holders, any
underwriters and their Special Counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as any Holder or underwriter
reasonably requests in writing, to keep each such registration or qualification
(or exemption therefrom) effective during the Effectiveness Period and to do any
and all other acts or things reasonably necessary or advisable to enable the
disposition in such jurisdictions of the Registrable Securities covered by a
Registration Statement; provided, however, that the Company shall not be
                        --------  -------                               
required to qualify generally to do business in any jurisdiction where it is not
then so qualified or to take 

                                      -7-
<PAGE>
 
any action that would subject it to general service of process in any such
jurisdiction where it is not then so subject or subject the Company to any
material tax in any such jurisdiction where it is not then so subject.

          (j) Cooperate with the Holders and any managing underwriters to
facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be delivered to a transferee pursuant to a
Registration Statement, which certificates shall be free, to the extent
permitted by applicable law, of all restrictive legends, and to enable such
Registrable Securities to be in such denominations and registered in such names
as any such managing underwriters or Holders may request.

          (k) Upon the occurrence of any event contemplated by Section 3(d)(vi),
as promptly as reasonably possible, prepare a supplement or amendment, including
a post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.

          (l) Use its best efforts to cause all Registrable Securities relating
to such Registration Statement to be listed on the Nasdaq National Market
("NASDAQ") or on any other stock market or trading facility on which the shares
  ------

          (m) Enter into such agreements (including an underwriting agreement in
form, scope and substance as is customary in Underwritten Offerings) and take
all such other actions in connection therewith (including those reasonably
requested by any managing underwriters and the Holders of a majority of the
Registrable Securities being sold) in order to expedite or facilitate the
disposition of such Registrable Securities, and whether or not an underwriting
agreement is entered into, (i) make such representations and warranties to such
Holders and such underwriters as are customarily made by issuers to underwriters

the Company and updates thereof addressed to each Holder and each such
underwriter, in form, scope and substance reasonably satisfactory to any such
managing underwriters and Special Counsel to the selling Holders covering the
matters customarily covered in opinions requested in Underwritten Offerings and
such other matters as may be reasonably requested by such Special Counsel and
underwriters; (iii) immediately prior to the effectiveness of the Registration
Statement, and, in the case of an Underwritten Offering, at the time of delivery

independent certified public accountants of the Company (and, if necessary, any
other independent certified public accountants of any subsidiary 

                                      -8-

statements and financial data is, or is required to be, included in the

customary in connection with Underwritten Offerings; (iv) if an underwriting
agreement is entered into, the same shall contain indemnification provisions and
procedures no less favorable to the selling Holders and the under writers, if

Registrable Securities participating in such Underwritten Offering); and (v)
deliver such documents and certificates as may be reason ably requested by the
Holders of a majority of the Registrable Securities being sold, their Special
Counsel and any managing underwriters to evidence the continued validity of the
representations and warranties made pursuant to Section 3(m)(i) above and to
evidence compliance with any customary conditions contained in the underwriting
agreement or other agreement entered into by the Company.

          (n) Make available for inspection by the selling Holders, any
representative of such Holders, any underwriter participating in any disposition
of Registrable Securities, and any attorney or accountant retained by such
selling Holders or underwriters, at the offices where normally kept, during
reasonable business hours, all financial and other records, pertinent corporate
documents and properties of the Company and its subsidiaries, and cause the
officers, directors, agents and employees of the Company and its subsidiaries to
supply all information in each case reasonably requested by any such Holder,
representative, underwriter, attorney or accountant in connection with the
Registration Statement; provided, however, that any information that is
                        --------  -------

such Person, is required by law; (iii) such information becomes generally
available to the public other than as a result of a disclosure or failure to

Company such information regarding the distribution of such Registrable
Securities and the beneficial ownership of Common Stock held by such Holder as
is required by law to be disclosed in the Registration Statement and as shall be
reasonably required to effect the registration of their Registrable Securities,
and the Company may exclude from such registration the Registrable Securities of
any such Holder who unreasonably fails to furnish such information within a
reasonable time after receiving such request.

          If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any 

                                      -9-

similar Federal statute then in force) the deletion of the reference to such
Holder in any amendment or supplement to the Registration Statement filed or

any post-effective amendments thereto have become effective as contemplated by
Section 3(d) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to
the Registration Statement.

that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Sections 3(d)(ii), 3(d)(iii), 3(d)(iv), 3(d)(v) or
3(d)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(k), or until it is advised in writing (the "Advice")
                                                                      ------

either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

prospectus or in any amendment or supplement thereto or in any preliminary
prospectus, or arising out of or relating to any omission or alleged omission of
a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in light of the circumstances under which they were made)
not misleading, except to the extent, but only to the extent, that such untrue
statements or omissions are based solely upon information regarding such Holder
furnished in writing to the Company by such Holder expressly for use therein, or
to the extent that such information relates to such Holder or such Holder's
proposed method of distribution of Registrable Securities and was reviewed and
expressly approved in writing by such Holder expressly for use in the
Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto. The Company shall notify the Holders promptly
of the institution, threat or assertion of any Proceeding of which the Company
is aware in connection with the transactions contemplated by this Agreement.

          (b)  Indemnification by Holders.  Each Holder shall, severally and not
               --------------------------                                       
jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising solely out of or based solely upon any untrue
statement of a material fact contained in the Registration Statement, any
Prospectus, or any form of prospectus, or in any amendment or supplement
thereto, or arising solely out of or based solely upon any omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in the Registration
Statement or such Prospectus or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by counsel
designated by the Holders to review such Registration Statement expressly for
use in the Registration Statement, such Prospectus or such form of Prospectus,
or in any amendment or supplement thereto.  In no event shall the liability of
any selling Holder hereunder be greater in 

                                      -12-
<PAGE>
 
amount than the dollar amount of the net proceeds (net of brokerage commissions)
received by such Holder upon the sale of the Registrable Securities giving rise
to such indemnification obligation.

          (c)  Conduct of Indemnification Proceedings. If any Proceeding shall
               --------------------------------------
be brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party shall promptly notify the Person
 -----------------                                                           
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
                                    ------------------                      
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the payment of all
fees and expenses incurred in connection with defense thereof; provided, that
the failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally determined by a court
of competent jurisdiction (which determination is not subject to appeal or
further review) that such failure shall have proximately and materially
adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless:  (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party).  The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

          All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent incurred in connection with investigating or
preparing to defend such Proceeding in a manner not inconsistent with this
Section) shall be paid to the Indemnified Party, as incurred, within ten (10)
Business Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
                           --------                                         
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

                                      -13-
<PAGE>

          (d)  Contribution.  If a claim for indemnification under Section 5(a)
               ------------                                                    
or 5(b) is unavailable to an Indemnified Party (by reason of public policy or
otherwise), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action, statement or omission.  The amount paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys' or
other reasonable fees or expenses incurred by such party in connection with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the indemnification provided for in this Section was available to
such party in accordance with its terms.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
                                                              --- ----
allocation or by any other method of allo cation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.  No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

     6.   Miscellaneous
          -------------

          (a)  Transferability.  Registrable Securities may only be disposed of
               ---------------                                                 
pursuant to an effective Registration Statement, to the Company or pursuant to
an available exemption from or in a transaction not subject to, the registration
requirements of the Securities Act. Notwithstanding anything herein to the
contrary, the Registrable Securities may be transferred to an Affiliate (as
defined in Rule 405 under the Securities Act) of the Purchaser or to one or more
funds under common management with the Purchaser, and among any such Affiliates
or one or more funds, provided that any such transferee certifies to the Company
that it is an "accredited investor" as defined in Rule 501(a) under the
Securities Act and that it is acquiring the Securities solely for investment
purposes. Any such transferee shall agree in writing to be bound by the terms of
this Agreement and shall have the rights of the Purchaser under this Agreement.
In addition, the Company shall cooperate reasonably with the Purchaser and such
assignee or transferee in connection with such assignment or transfer in order
to permit such assignee or transferee to resell Registrable Securities under a
Registration Statement.

          (b)  Remedies. In the event of a breach by the Company or by a Holder,
               --------                                                      
of any of their obligations under this Agreement, each Holder or the Company, as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement.  The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

          (c)  No Inconsistent Agreements.  Neither the Company nor any of its
               --------------------------                                     
subsidiaries has, as of the date hereof, nor shall the Company or any of its
subsidiaries, on or after the date of this Agreement, enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Holders in this Agreement or otherwise conflicts with the provisions hereof.
Except as and to the extent specified in Schedule 6(c) hereto, neither the
                                         -------------                    
Company nor any of its subsidiaries has previously entered into any agreement
granting any registration rights with respect to any of its securities to any
Person.  Without limiting the generality of the foregoing, without the written
consent of the Holders of a majority of the then outstanding Registrable
Securities, the Company shall not grant to any Person the right to request the
Company to register any securities of the Company under the Securities Act
unless the rights so granted are subject in all respects to the prior rights in
full of the Holders set forth herein, and are not otherwise in conflict or
inconsistent with the provisions of this Agreement.

          (d)  No Piggyback on Registrations.  Except as and to the extent
               -----------------------------                              
specified in Schedule 6(c) hereto, neither the Company nor any of its security
             -------------                                                    
holders (other than the Holders in such capacity pursuant hereto) may include
securities of the Company in the Registration Statement other than the
Registrable Securities, and the Company shall not after the date hereof enter
into any agreement providing any such right to any of its security holders.

                                      -15-
<PAGE>

          (e)  Piggy-Back Registrations.  If at any time when there is not an
               ------------------------                                      
effective Registration Statement covering all of the Registrable Securities the
Company shall determine to prepare and file with the Commission a registration
statement relating to an offering for its own account or the account of others
under the Securities Act of any of its equity securities, other than on Form S-4
or Form S-8 (each as promulgated under the Securities Act) or their then
equivalents relating to equity securities to be issued solely in connection with
any acquisition of any entity or business or equity securities issuable in
connection with stock option or other employee benefit plans, then the Company
shall send to each holder of Registrable Securities written notice of such
determination and, if within twenty (20) days after receipt of such notice, any
such Holder shall so request in writing, the Company shall include in such
registration statement all or any part of such Registrable Securities such
Holder requests to be registered; provided, however, that the Company shall not
                                  --------  -------                            
be required to register any Registrable Securities pursuant to this Section 7(d)
that are eligible for sale pursuant to Rule 144(k) of the Commission.

          In connection with any offering by the Company  involving an
underwriting of shares of Common Stock to be issued for the account of a
stockholder of the Company other than a Holder, if such offering is one in which
a Holder has elected to participate pursuant to this Section 6(e) and the
managing underwriter has imposed a limitation on the number of shares of Common
Stock which may be included in any such registration statement because, in its
judgment, such limitation is necessary to effect an orderly public distribution
of the shares of Common Stock and to maintain a stable market for the securities
of the Company, then the Company may cut-back the number of Registrable
Securities to be included in such registration statement on the following basis:
if the registration statement is for the account of a selling stockholder other
than a Holder, then all classes of the Company's stock other than the initiating
securityholder for whom such registration is intended shall first be cut-back,
provided, that all classes of the Company's stock other than the Series A
Convertible Preferred Stock and the Registrable Securities shall be cut back in
full prior to any cut-back to the Series A Preferred and the Registrable
Securities and, thereafter, the holders of the Series A Convertible Preferred
Stock and the Registrable Securities hereunder shall be cut-back pro rata, based
upon the number of shares of Common Stock and the Registrable Securities then
held by such participating securityholder.  The Holders will not be subject to
any underwriter cutback in the event of any underwritten offering of Common
Stock by the Company on a primary basis.

          (f)  Amendments and Waivers.  The provisions of this Agreement,
               ----------------------                                    
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of at least two-thirds of the then outstanding Registrable
Securities; provided, however, that, for the purposes of this sentence,
            --------  -------                                          
Registrable Securities that are owned, directly or indirectly, by the Company,
or an Affiliate of the Company are not deemed outstanding.  Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates exclusively to the rights of Holders and that does not
directly or indirectly affect the rights of other Holders may be given by
Holders of at least a majority of the Registrable Securities to which such
waiver or consent relates; provided, 
                           --------  

                                      -16-

however, that the provisions of this sentence may not be amended, modified, or
- -------
supplemented except in accordance with the provisions of the immediately
preceding sentence.

Securities is required hereunder, Registrable Securities held by the Company or

                                                                         -------

                             PLAN OF DISTRIBUTION
                             --------------------


     The Selling Stockholders and any of their pledgees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares
of Common Stock on any stock exchange, market or trading facility on which the
shares are traded or in private transactions.  These sales may be at fixed or
negotiated prices.  The Selling Stockholders may use any one or more of the
following methods when selling shares:

 .    ordinary brokerage transactions and transactions in which the broker-
     dealer solicits purchasers;

 .    block trades in which the broker-dealer will attempt to sell the shares as
     agent but may position and resell a portion of the block as principal to
     facilitate the transaction;

 .    purchases by a broker-dealer as principal and resale by the broker-dealer
     for its account;

 .    an exchange distribution in accordance with the rules of the applicable
     exchange;

 .    privately negotiated transactions;

 .    short sales;

 .    broker-dealers may agree with the Selling Stockholders to sell a specified
     number of such shares at a stipulated price per share;

 .    a combination of any such methods of sale; and

 .    any other method permitted pursuant to applicable law.

     The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

     The Selling Stockholders may pledge their shares to their brokers under the
margin provisions of customer agreements.  If a Selling Stockholder defaults on
a margin loan, the broker may, from time to time, offer and sell the pledged
shares.

     Broker-dealers engaged by the Selling Stockholders may arrange for other
brokers-dealers to participate in sales.  Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated.  The Selling Stockholders do not 

                                       22
<PAGE>
 
expect these commissions and discounts to exceed what is customary in the types
of transactions involved.

     The Selling Stockholders and any broker-dealers or agents that are involved
in selling the shares may be deemed to be "underwriters" within the meaning of
the Securities Act in connection with such sales. In such event, any commissions
received by such broker-dealers or agents and any profit on the resale of the
shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act.

     The Company is required to pay all fees and expenses incident to the
registration of the shares, including fees and disbursements of counsel to the
Selling Stockholders. The Company has agreed to indemnify the Selling
Stockholders against certain losses, claims, damages and liabilities, including
liabilities under the Securities Act.

              SCHEDULE 6(C) TO THE REGISTRATION RIGHTS AGREEMENT
              --------------------------------------------------



     Silicon Graphics, Inc. ("SGI") currently owns 3,350,894 shares of Series A 
Preferred Stock, $.01 par value per share, (the "Series A Preferred") and a 
warrant to purchase for a period of three years commencing on August 11, 1998 at
an exercise price of $2.75 per share up to that number of shares of Series A 
Preferred Stock equal to 3% of the Company's then issued and outstanding Common 
Stock at the time of exercise (the shares underlying the Warrant together with 
the Series A Preferred, "the SGI Shares"). The Company and SGI have entered into
the following agreements regarding the SGI Shares:

1.   An Investor Rights Agreement dated August 11, 1998 by and between the 
     Company and SGI.

2.   A Registration Rights Agreement by and between the Company and SGI dated 
     March 31, 1999 attached to Schedule 6(c) hereto.

                             FORM OF LEGAL OPINION

     1.   Each of the Company and its Subsidiaries is a corporation, duly 
incorporated, validly existing and in corporate good standing under the laws of 
the jurisdiction of its incorporation, with the requisite corporate power and 
authority to own and use its properties and assets and to carry on its business
as currently conducted. The Company has no subsidiaries other than the 
Subsidiaries. Each of the Company and the Subsidiaries is duly qualified to do 
business and is in corporate good standing as a foreign corporation in each 
jurisdiction in which the nature of the business conducted or property owned by 
it makes such qualification necessary or where the failure to so qualify would 
not have a materially adverse effect on the Company and/or its Subsidiaries.

     2.   The Company has the requisite corporate power and authority to enter
into and to consummate the transactions contemplated by each of the Transaction 
Documents and otherwise to carry out its obligations thereunder. The execution 
and delivery of each of the Transaction Documents by the Company and the 
consummation by it of the transactions contemplated thereby have been duly 
authorized by all necessary action on the part of the Company. Each of the 
Transaction Documents has been duly executed and delivered by the Company and 
constitutes the legal, valid and binding obligation of the Company enforceable 
against the Company in accordance with its terms, except as such enforceability 
may be limited as stated in this opinion.

     3.   Except as set forth in the Disclosure Schedules to the Purchase 
Agreement, no shares of common stock of the Company, par value $.01 per share 
("Common Stock"), are entitled to preemptive or similar rights.
  ------------

     4.   The Shares and the Warrant have been duly authorized and, when paid 
for and issued in accordance with the terms of the Purchase Agreement shall have
been validly issued, fully paid and nonassessable.

     5.   The Company has duly authorized (subject to shareholder approval as 
contemplated by Section 5 of the Certificate of Designation) and reserved for
issuance the Initial Minimum as required pursuant to the terms of the Purchase
Agreement, the Certificate of Designation and the Warrant, respectively. When
issued by the Company in accordance with the terms of the Purchase Agreement,
the Certificate of Designation and the Warrant (as the case may be), such
Underlying Shares will be validly issued, fully paid and nonassessable.

     6.   The execution, delivery and performance of the Transaction Documents 
by the Company and the consummation by the Company of the transactions 
contemplated by such agreements do not and will not (i) conflict with or violate
any provision of its Certificate of Incorporation or Bylaws, (ii)(A) except as 
set forth in the Disclosure Schedule to the Purchase

<PAGE>
 
Agreement, conflict with, or constitute a default (or an event which with notice
or lapse of time or both would become a default) under, or give to others any 
rights of termination, amendment, acceleration or cancellation of, any 
agreement, indenture or other written instrument relating to indebtedness of the
Company or instrument to which the Company is a party and filed by the Company 
with the Securities and Exchange Commission since January 1, 1997, or (B) to our
knowledge, conflict with, or constitute a default under any other material 
agreements to which the Company is a party, or (iii) result in (a) a violation 
of any law, rule or regulation (other than state and foreign blue sky laws), or 
(b) any order, judgment, injunction, decree or other restriction, to our 
knowledge, of any court or governmental authority to which the Company is 
subject, or by which any property or asset of the Company is bound or affected 
or any other restriction of which we have knowledge. To our knowledge, the 
business of the Company is not being conducted in violation of any law,
ordinance or regulation of any governmental authority, the violation of which
would have a materially adverse effect on the Company.

     7.   Other than the Required Approvals, neither the Company nor any 
Subsidiary is required to obtain any consent, waiver, authorization or order of,
or make any filing or registration with, any court or other Federal, state, 
local or other governmental authority or other person in connection with the 
execution, delivery and performance by the Company of the Transaction Documents.
Notwithstanding the foregoing, no opinion is provided hereunder as to whether 
the issuance of the Shares or the Warrant to the Purchasers requires a filing 
with the U.S. Department of Justice in accordance with the provisions of the 
Hart-Scott-Rodino Act.

     8.   To our knowledge, the Company has filed all reports required to be 
filed by it under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), including pursuant to Section 13(a) or 15(d) thereof, for the two years 
preceding the date hereof (or such shorter period as the Company was required by
law to file such material) (collectively, the "SEC Documents") on a timely 
basis, or has received a valid extension of such time of filing and made such 
filing within the applicable grace period. As of their respective dates, the SEC
Documents complied in all material respects as to form with the requirements of 
the Securities Act and the Exchange Act and the rules and regulations of the 
Securities and Exchange Commission promulgated thereunder.

     9.   Assuming the accuracy of the representations and warranties of the 
Company set forth in Section 2.1 of the Purchase Agreement and of the Purchaser
set forth in Section 2.2 of the Purchase Agreement, the offer, issuance and sale
of the Shares and the Warrant and the offer, issuance and sale of the Underlying
Shares to the Purchasers pursuant to the Purchase Agreement, the Certificate of 
Designation and the Warrant are exempt from the registration requirements of the
Securities Act.

                   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-

               (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
               -------

or (iv) upon actual receipt by the party to whom such notice is required to be

Holder at the address or facsimile number appearing on the Warrant Register or

          13.  Warrant Agent.  The Company shall serve as warrant agent under
               -------------                                                 
this Warrant. Upon thirty (30) days' notice to the Holder, the Company may
appoint a new warrant agent. Any corporation into which the Company or any new
warrant agent may be merged or any corporation resulting from any consolidation
to which the Company or any new warrant agent shall be a party or any
corporation to which the Company or any new warrant agent transfers
substantially all of its corporate trust or shareholders services business shall

          14.  Miscellaneous.
               ------------- 

               (a) This Warrant shall be binding on and inure to the benefit of

                          TRANSFER AGENT INSTRUCTIONS



Ladies and Gentlemen:

     Reference is made to that certain Convertible Preferred Stock Purchase 
Agreement (the "PURCHASE AGREEMENT") between Number Nine Visual Technology 
Corporation, a Delaware corporation (the "COMPANY"), and the buyer named 
therein (the "HOLDER") pursuant to which the Company is issuing to the Holder 
its shares of 4% Series B Convertible Preferred Stock, par value $.01 per 
share (the "PREFERRED SHARES"), and a Common Stock purchase warrant 
(the "WARRANT") which shall be convertible and exercisable, respectively, 
into shares of the Common Stock issuable upon conversion of the Preferred 
Shares, payment of dividends thereon, and upon exercise of the Warrant are 
collectively referred to herein as "UNDERLYING SHARES."

      This letter shall serve as our irrevocable authorization and direction
to you (provided that you are the transfer agent for the Company with respect to
its Common Stock at such time) to issue Underlying Shares from time to time
upon notice from the Company to issue such Underlying Shares. So long as you
have previously received (x) an opinion of the Company's outside counsel
substantially in the form of EXHIBIT 1 attached hereto (which the Company shall
direct be delivered to you by such outside counsel upon the effectiveness of the
registration statement covering resales of Underlying Shares) stating that a
registration statement covering resales of Underlying Shares has been declared
effective by the Securities and Exchange Commission under the Securities Act
of 1933, as amended, and that Underlying Shares may be issued (or reissued
if they have been issued at a time when there was not such an effective
registration statement) or resold without any restrictive legend 
(the "OPINION") and (y) a copy of such registration statement, then certificates
representing Underlying Shares shall not bear any legend restricting transfer
of Underlying Shares thereby and should not be subject to any stop-transfer 
restriction. Provided, however, that if you have not previously received a 
copy of the Opinion and such registration statement, then the certificates 
representing Underlying Shares shall bear the following legend.

                                      -1-

<PAGE>
 
          THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND 
     EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE
     UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR
     SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
     SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A
     TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES
     ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS.

and, provided, further, that the Company may, from time to time, notify you to 
place stop-transfer restrictions on the certificates for Underlying Shares in 
the event, but only in the event, a registration statement covering Underlying 
Shares is subject to amendment for events then current.

     Please be advised that the Holder has relied upon this instruction letter 
as an inducement to enter into the Purchase Agreement and, accordingly, the 
Holder is a third party beneficiary to these instructions, provided, that any 
rights the Holder may have may only be exercised against the Company.

          (a) On or prior to the Filing Date, the Company shall prepare and file

keep such Registration Statement continuously effective under the Securities Act

Effectiveness Period if it voluntarily takes any action that would result in the
Holders not being able to sell the Registrable Securities covered by such
Registration Statement during the Effectiveness Period, unless such action is
required under applicable law or the Company has filed a post-effective
amendment to the Registration Statement and the Commission has not declared it
effective.

          (b) If the Holders of a majority of the Registrable Securities so
elect, an offering of Registrable Securities pursuant to the Registration
Statement may be effected in the form of an Underwritten Offering.  In such
event, and, if the managing underwriters advise the Company and such Holders in
writing that in their opinion the amount of Registrable Securities proposed to
be sold in such Underwritten Offering exceeds the amount of Registrable
Securities which can be sold in such Underwritten Offering, there shall be
included in such Underwritten Offering the amount of such Registrable Securities
which in the opinion of such managing underwriters can be sold, and such amount

Securities in such Underwritten Offering.

Underwritten Offering, the investment banker in interest that will administer
the offering will be selected by the Holders of a majority of the Registrable
Securities included in such offering subject to the Company's right to approve
such underwriter (which may not be reasonably withheld or delayed).  No Holder
may participate in any Underwritten Offering hereunder unless such Holder (i)
agrees to sell its Registrable Securities on the basis provided in any
underwriting agreements approved by the Persons entitled hereunder to approve
such arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such arrangements.

file such additional Registration Statements after its receipt of notice of the
requirement thereof which the Holders may give at any time when the Registrable
Securities exceeds 85% of the number of shares of Common Stock then registered
in a Registration Statement hereunder.  In such event, the Registration
Statement required to be filed by the Company shall include no less than a

Company's obligation to issue shares of Common Stock pursuant to Sections
5(a)(iii)(B) and (C) of the Certificate of Designation, no less than 200% of the
number of shares of Common Stock into which all then outstanding shares of
Preferred Stock are convertible (assuming such conversion occurred on the Filing
Date for such Registration Statement or the date of the filing of the final
acceleration request therefor, whichever  date yields a lower Conversion Price)
and any other Registrable Securities not then registered in a Registration
Statement.

          (d) Notify the Holders of Registrable Securities to be sold, their

any Prospectus supplement or post-effective amendment to the Registration
Statement is proposed to be filed; (B) when the Commission notifies the Company

provide true and complete copies thereof and all written responses thereto to
each of the Holders); and (C) with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority

purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement (including any underwriting agreement)
contemplated hereby ceases to be true and correct in all material respects; (v)
of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose; and (vi) of the occurrence of any event that makes
any statement made in the Registration Statement or Prospectus or any document
incorporated or deemed to be incorporated therein by reference untrue in any
material respect or that requires any revisions to the Registration Statement,
Prospectus or other documents so that, in the case of the Registration Statement
or the Prospectus, as the case may be, it will not contain any untrue statement
of a material fact or omit to state any

                                      -6-
<PAGE>
 
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

          (e) Use its best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of (i) any order suspending the effectiveness of the
Registration Statement, or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

          (f) If requested by any managing underwriter or the Holders of a
majority in interest of the Registrable Securities to be sold in connection with
an Underwritten Offering, (i) promptly incorporate in a Prospectus supplement or
post-effective amendment to the Registration Statement such information as such
managing underwriters and such Holders reasonably agree should be included
therein, and (ii) make all required filings of such Prospectus supplement or
such post-effective amendment as soon as practicable after the Company has
received notification of the matters to be incorporated in such Prospectus
supplement or post-effective amendment; provided, however, that the Company
                                        --------  -------

underwriters, without charge, at least one conformed copy of each Registration
Statement and each amendment thereto, including financial statements and

underwriters and their Special Counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as any Holder or underwriter
reasonably requests in writing, to keep each such registration or qualification
(or exemption therefrom) effective during the Effectiveness Period and to do any
and all other acts or things reasonably necessary or advisable to enable the
disposition in such jurisdictions of the Registrable Securities covered by a
Registration Statement; provided, however, that the Company shall not be
                        --------  -------                               
required to qualify generally to do business in any jurisdiction where it is not
then so qualified or to take 

                                      -7-

any action that would subject it to general service of process in any such
jurisdiction where it is not then so subject or subject the Company to any
material tax in any such jurisdiction where it is not then so subject.

facilitate the timely preparation and delivery of certificates representing

Registrable Securities to be in such denominations and registered in such names
as any such managing underwriters or Holders may request.

as promptly as reasonably possible, prepare a supplement or amendment, including
a post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus

fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.

                                                      -----------------         
when required pursuant to the Purchase Agreement.

          (m) Enter into such agreements (including an underwriting agreement in
form, scope and substance as is customary in Underwritten Offerings) and take
all such other actions in connection therewith (including those reasonably
requested by any managing underwriters and the Holders of a majority of the
Registrable Securities being sold) in order to expedite or facilitate the
disposition of such Registrable Securities, and whether or not an underwriting
agreement is entered into, (i) make such representations and warranties to such
Holders and such underwriters as are customarily made by issuers to underwriters
in underwritten public offerings, and confirm the same if and when requested;
(ii) in the case of an Underwritten Offering obtain and deliver copies thereof
to each Holder and the managing underwriters, if any, of opinions of counsel to
the Company and updates thereof addressed to each Holder and each such
underwriter, in form, scope and substance reasonably satisfactory to any such
managing underwriters and Special Counsel to the selling Holders covering the
matters customarily covered in opinions requested in Underwritten Offerings and
such other matters as may be reasonably requested by such Special Counsel and
underwriters; (iii) immediately prior to the effectiveness of the Registration
Statement, and, in the case of an Underwritten Offering, at the time of delivery
of any Registrable Securities sold pursuant thereto, use its best reasonable
efforts to obtain and deliver copies to the Holders and the managing
underwriters, if any, of "cold comfort" letters and updates thereof from the
independent certified public accountants of the Company (and, if necessary, any
other independent certified public accountants of any subsidiary 

                                      -8-

of the Company or of any business acquired by the Company for which financial
statements and financial data is, or is required to be, included in the
Registration Statement), addressed to the Company in form and substance as are
customary in connection with Underwritten Offerings; (iv) if an underwriting
agreement is entered into, the same shall contain indemnification provisions and
procedures no less favorable to the selling Holders and the under writers, if
any, than those set forth in Section 5 (or such other provisions and procedures
acceptable to the managing underwriters, if any, and holders of a majority of
Registrable Securities participating in such Underwritten Offering); and (v)
deliver such documents and certificates as may be reason ably requested by the
Holders of a majority of the Registrable Securities being sold, their Special
Counsel and any managing underwriters to evidence the continued validity of the
representations and warranties made pursuant to Section 3(m)(i) above and to
evidence compliance with any customary conditions contained in the underwriting
agreement or other agreement entered into by the Company.

          (n) Make available for inspection by the selling Holders, any
representative of such Holders, any underwriter participating in any disposition
of Registrable Securities, and any attorney or accountant retained by such
selling Holders or underwriters, at the offices where normally kept, during
reasonable business hours, all financial and other records, pertinent corporate
documents and properties of the Company and its subsidiaries, and cause the
officers, directors, agents and employees of the Company and its subsidiaries to
supply all information in each case reasonably requested by any such Holder,
representative, underwriter, attorney or accountant in connection with the
Registration Statement; provided, however, that any information that is
                        --------  -------                              
determined in good faith by the Company in writing to be of a confidential
nature at the time of delivery of such information shall be kept confidential by
such Persons, unless (i) disclosure of such information is required by court or
administrative order or is necessary to respond to inquiries of regulatory
authorities; (ii) disclosure of such information, in the opinion of counsel to
such Person, is required by law; (iii) such information becomes generally
available to the public other than as a result of a disclosure or failure to
safeguard by such Person; or (iv) such information becomes available to such
Person from a source other than the Company and such source is not bound by a
confidentiality agreement with the Company.

          (o) Comply with all applicable rules and regulations of the
Commission.

          (p) The Company may require each selling Holder to furnish to the
Company such information regarding the distribution of such Registrable
Securities and the beneficial ownership of Common Stock held by such Holder as
is required by law to be disclosed in the Registration Statement and as shall be
reasonably required to effect the registration of their Registrable Securities,
and the Company may exclude from such registration the Registrable Securities of
any such Holder who unreasonably fails to furnish such information within a
reasonable time after receiving such request.

          If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any 

                                      -9-
<PAGE>
 
similar Federal statute then in force) the deletion of the reference to such
Holder in any amendment or supplement to the Registration Statement filed or
prepared subsequent to the time that such reference ceases to be required.

          Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(h) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(d) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to
the Registration Statement.

          Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Sections 3(d)(ii), 3(d)(iii), 3(d)(iv), 3(d)(v) or
3(d)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(k), or until it is advised in writing (the "Advice")
                                                                      ------
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

          4.   Registration Expenses
               ---------------------

                                      -10-
<PAGE>
 
          (a)  All fees and expenses incident to the performance of or
compliance with this Agreement by the Company, except as and to the extent
specified in Section 4(b), shall be borne by the Company whether or not pursuant
to an Underwritten Offering and whether or not the Registration Statement is
filed or becomes effective and whether or not any Registrable Securities are
sold pursuant to the Registration Statement. The fees and expenses referred to
in the foregoing sentence shall include, without limitation, (i) all
registration and filing fees (including, without limitation, reasonable fees and
expenses (A) with respect to filings required to be made with the NASDAQ and any
Subsequent Market on which the Common Stock is then listed for trading, and (B)
in compliance with state securities or Blue Sky laws (including, without
limitation, fees and disbursements of counsel for the Holders in connection with
Blue Sky qualifications or exemptions of the Registrable Securities and
determination of the eligibility of the Registrable Securities for investment
under the laws of such jurisdictions as the managing underwriters, if any, or
the Holders of a majority of Registrable Securities may designate)), (ii)
printing expenses (including, without limitation, expenses of printing
certificates for Registrable Securities and of printing prospectuses if the
printing of prospectuses is requested by the managing underwriters, if any, or

fees and disbursements of counsel for the Company and Special Counsel for the
Holders up to an aggregate of $7,500, (v) Securities Act liability insurance, if
the Company so desires such insurance, and (vi) fees and expenses of all other

without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange as required hereunder.

          (b)  If the Holders require an Underwritten Offering pursuant to the
terms hereof, the Company shall be responsible for all costs, fees and expenses
in connection therewith, except for the fees and disbursements of the
Underwriters (including any underwriting commissions and discounts and the costs
of printing prospectuses) and their legal counsel and accountants.  By way of
illustration which is not intended to diminish from the provisions of Section
4(a), the Holders shall not be responsible for, and the Company shall be
required to pay the fees or disbursements incurred by the Company (including by
its legal counsel and accountants) in connection with, the preparation and
filing of a Registration Statement and related Prospectus for such offering, the
maintenance of such Registration Statement in accordance with the terms hereof,
the listing of the Registrable Securities in accordance with the requirements
hereof, and printing expenses incurred to comply with the requirements hereof.

     5.   Indemnification
          ---------------

                                      -11-
<PAGE>
 
          (a)  Indemnification by the Company.  The Company shall,
               ------------------------------                     
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents (including any underwriters
retained by such Holder in connection with the offer and sale of Registrable
Securities), brokers (including brokers who offer and sell Registrable
Securities as principal as a result of a pledge or any failure to perform under
a margin call of Common Stock), investment advisors and employees of each of
them, each Person who controls any such Holder (within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act) and the officers,
directors, agents and employees of each such controlling Person, to the fullest
extent permitted by applicable law, from and against any and all losses, claims,
damages, liabilities, costs (including, without limitation, costs of preparation
and attorneys' fees) and expenses (collectively, "Losses"), as incurred, arising
                                                  ------                        
out of or relating to any untrue or alleged untrue statement of a material fact
contained in the Registration Statement, any Prospectus or any form of
prospectus or in any amendment or supplement thereto or in any preliminary
prospectus, or arising out of or relating to any omission or alleged omission of
a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in light of the circumstances under which they were made)
not misleading, except to the extent, but only to the extent, that such untrue
statements or omissions are based solely upon information regarding such Holder
furnished in writing to the Company by such Holder expressly for use therein, or
to the extent that such information relates to such Holder or such Holder's
proposed method of distribution of Registrable Securities and was reviewed and
expressly approved in writing by such Holder expressly for use in the
Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto. The Company shall notify the Holders promptly
of the institution, threat or assertion of any Proceeding of which the Company
is aware in connection with the transactions contemplated by this Agreement.

          (b)  Indemnification by Holders.  Each Holder shall, severally and not
               --------------------------                                       
jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising solely out of or based solely upon any untrue
statement of a material fact contained in the Registration Statement, any
Prospectus, or any form of prospectus, or in any amendment or supplement
thereto, or arising solely out of or based solely upon any omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in the Registration
Statement or such Prospectus or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by counsel
designated by the Holders to review such Registration Statement expressly for
use in the Registration Statement, such Prospectus or such form of Prospectus,
or in any amendment or supplement thereto.  In no event shall the liability of
any selling Holder hereunder be greater in 

                                      -12-
<PAGE>
 
amount than the dollar amount of the net proceeds (net of brokerage commissions)
received by such Holder upon the sale of the Registrable Securities giving rise
to such indemnification obligation.

          (c)  Conduct of Indemnification Proceedings. If any Proceeding shall
               --------------------------------------
be brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party shall promptly notify the Person
 -----------------                                                           
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
                                    ------------------                      
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the payment of all
fees and expenses incurred in connection with defense thereof; provided, that
the failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally determined by a court
of competent jurisdiction (which determination is not subject to appeal or
further review) that such failure shall have proximately and materially
adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless:  (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party).  The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

          All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent incurred in connection with investigating or
preparing to defend such Proceeding in a manner not inconsistent with this
Section) shall be paid to the Indemnified Party, as incurred, within ten (10)
Business Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
                           --------                                         
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

                                      -13-
<PAGE>
 
          (d)  Contribution.  If a claim for indemnification under Section 5(a)
               ------------                                                    
or 5(b) is unavailable to an Indemnified Party (by reason of public policy or
otherwise), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action, statement or omission.  The amount paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys' or
other reasonable fees or expenses incurred by such party in connection with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the indemnification provided for in this Section was available to
such party in accordance with its terms.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
                                                              --- ----
allocation or by any other method of allo cation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.  No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

                                      -14-

     6.   Miscellaneous
          -------------

          (a)  Transferability.  Registrable Securities may only be disposed of
               ---------------                                                 
pursuant to an effective Registration Statement, to the Company or pursuant to
an available exemption from or in a transaction not subject to, the registration
requirements of the Securities Act. Notwithstanding anything herein to the
contrary, the Registrable Securities may be transferred to an Affiliate (as
defined in Rule 405 under the Securities Act) of the Purchaser or to one or more
funds under common management with the Purchaser, and among any such Affiliates
or one or more funds, provided that any such transferee certifies to the Company
that it is an "accredited investor" as defined in Rule 501(a) under the
Securities Act and that it is acquiring the Securities solely for investment
purposes. Any such transferee shall agree in writing to be bound by the terms of
this Agreement and shall have the rights of the Purchaser under this Agreement.
In addition, the Company shall cooperate reasonably with the Purchaser and such
assignee or transferee in connection with such assignment or transfer in order
to permit such assignee or transferee to resell Registrable Securities under a
Registration Statement.

          (b)  Remedies. In the event of a breach by the Company or by a Holder,
               --------                                                      
of any of their obligations under this Agreement, each Holder or the Company, as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement.  The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

          (c)  No Inconsistent Agreements.  Neither the Company nor any of its
               --------------------------                                     
subsidiaries has, as of the date hereof, nor shall the Company or any of its
subsidiaries, on or after the date of this Agreement, enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Holders in this Agreement or otherwise conflicts with the provisions hereof.
Except as and to the extent specified in Schedule 6(c) hereto, neither the
                                         -------------                    
Company nor any of its subsidiaries has previously entered into any agreement
granting any registration rights with respect to any of its securities to any
Person.  Without limiting the generality of the foregoing, without the written
consent of the Holders of a majority of the then outstanding Registrable
Securities, the Company shall not grant to any Person the right to request the
Company to register any securities of the Company under the Securities Act
unless the rights so granted are subject in all respects to the prior rights in
full of the Holders set forth herein, and are not otherwise in conflict or
inconsistent with the provisions of this Agreement.

          (d)  No Piggyback on Registrations.  Except as and to the extent
               -----------------------------                              
specified in Schedule 6(c) hereto, neither the Company nor any of its security
             -------------                                                    
holders (other than the Holders in such capacity pursuant hereto) may include
securities of the Company in the Registration Statement other than the
Registrable Securities, and the Company shall not after the date hereof enter
into any agreement providing any such right to any of its security holders.

                                      -15-
<PAGE>
 
          (e)  Piggy-Back Registrations.  If at any time when there is not an
               ------------------------                                      
effective Registration Statement covering all of the Registrable Securities the
Company shall determine to prepare and file with the Commission a registration
statement relating to an offering for its own account or the account of others
under the Securities Act of any of its equity securities, other than on Form S-4
or Form S-8 (each as promulgated under the Securities Act) or their then
equivalents relating to equity securities to be issued solely in connection with
any acquisition of any entity or business or equity securities issuable in
connection with stock option or other employee benefit plans, then the Company
shall send to each holder of Registrable Securities written notice of such
determination and, if within twenty (20) days after receipt of such notice, any
such Holder shall so request in writing, the Company shall include in such
registration statement all or any part of such Registrable Securities such
Holder requests to be registered; provided, however, that the Company shall not
                                  --------  -------                            
be required to register any Registrable Securities pursuant to this Section 7(d)
that are eligible for sale pursuant to Rule 144(k) of the Commission.

          In connection with any offering by the Company  involving an
underwriting of shares of Common Stock to be issued for the account of a
stockholder of the Company other than a Holder, if such offering is one in which
a Holder has elected to participate pursuant to this Section 6(e) and the
managing underwriter has imposed a limitation on the number of shares of Common
Stock which may be included in any such registration statement because, in its
judgment, such limitation is necessary to effect an orderly public distribution
of the shares of Common Stock and to maintain a stable market for the securities
of the Company, then the Company may cut-back the number of Registrable
Securities to be included in such registration statement on the following basis:
if the registration statement is for the account of a selling stockholder other
than a Holder, then all classes of the Company's stock other than the initiating
securityholder for whom such registration is intended shall first be cut-back,
provided, that all classes of the Company's stock other than the Series A
Convertible Preferred Stock and the Registrable Securities shall be cut back in
full prior to any cut-back to the Series A Preferred and the Registrable
Securities and, thereafter, the holders of the Series A Convertible Preferred
Stock and the Registrable Securities hereunder shall be cut-back pro rata, based
upon the number of shares of Common Stock and the Registrable Securities then
held by such participating securityholder.  The Holders will not be subject to
any underwriter cutback in the event of any underwritten offering of Common
Stock by the Company on a primary basis.

          (f)  Amendments and Waivers.  The provisions of this Agreement,
               ----------------------                                    
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of at least two-thirds of the then outstanding Registrable
Securities; provided, however, that, for the purposes of this sentence,
            --------  -------                                          
Registrable Securities that are owned, directly or indirectly, by the Company,
or an Affiliate of the Company are not deemed outstanding.  Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates exclusively to the rights of Holders and that does not
directly or indirectly affect the rights of other Holders may be given by

                                                                         -------

                             PLAN OF DISTRIBUTION
                             --------------------


     The Selling Stockholders and any of their pledgees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares
of Common Stock on any stock exchange, market or trading facility on which the
shares are traded or in private transactions.  These sales may be at fixed or
negotiated prices.  The Selling Stockholders may use any one or more of the
following methods when selling shares:

 .    ordinary brokerage transactions and transactions in which the broker-
     dealer solicits purchasers;

 .    block trades in which the broker-dealer will attempt to sell the shares as
     agent but may position and resell a portion of the block as principal to
     facilitate the transaction;

 .    purchases by a broker-dealer as principal and resale by the broker-dealer
     for its account;

 .    an exchange distribution in accordance with the rules of the applicable
     exchange;

 .    privately negotiated transactions;

 .    short sales;

 .    broker-dealers may agree with the Selling Stockholders to sell a specified
     number of such shares at a stipulated price per share;

 .    a combination of any such methods of sale; and

 .    any other method permitted pursuant to applicable law.

     The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

     The Selling Stockholders may pledge their shares to their brokers under the
margin provisions of customer agreements.  If a Selling Stockholder defaults on
a margin loan, the broker may, from time to time, offer and sell the pledged
shares.

     Broker-dealers engaged by the Selling Stockholders may arrange for other
brokers-dealers to participate in sales.  Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated.  The Selling Stockholders do not 

                                       22
<PAGE>
 
expect these commissions and discounts to exceed what is customary in the types
of transactions involved.

     The Selling Stockholders and any broker-dealers or agents that are involved
in selling the shares may be deemed to be "underwriters" within the meaning of
the Securities Act in connection with such sales. In such event, any commissions
received by such broker-dealers or agents and any profit on the resale of the
shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act.

     The Company is required to pay all fees and expenses incident to the
registration of the shares, including fees and disbursements of counsel to the
Selling Stockholders. The Company has agreed to indemnify the Selling
Stockholders against certain losses, claims, damages and liabilities, including
liabilities under the Securities Act.

Company may deem and treat the registered Holder of this Warrant as the absolute

          (a) The Company shall register the transfer of any portion of this

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,
including the obligations with regard to a mandatory conversion as set forth
herein.

          (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, Exercise of Warrants and Redemption.
         --------------------- ------------ ---------- 

          (a) This Warrant shall be exercisable by the registered Holder on any
business day before 5:00 P.M., Eastern Standard time, at any time and from time
to time on or after March 31, 1999 to and including 5:00 P.M. Boston time on
March 31, 2002 (the "Expiration Date"). At 5:00 P.M., Eastern Standard time on
the Expiration Date, the portion of this Warrant not exercised prior thereto

          (b) Subject to Sections 2(b), 5 and 9, upon surrender of this Warrant,

Exercise Price multiplied by the number of Warrant Shares that the Holder
intends to purchase hereunder, in lawful money of the United States of America,
by certified or official bank check or checks or wire transfer, all as specified
by the Holder in the Form of Election to Purchase, the Company shall promptly
(but in no event later than five (5) 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 other than legends which the Company may reasonably
deem necessary to comply with applicable state and federal securities laws for
the issuance of such securities and any legends placed on all registered shares
of the Company relating to the then current agreement between the Company and
its transfer agent relating to the issuance of "rights" to all holders of the
Company's Common Stock. Any person so designated 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

Election to Purchase attached hereto (or attached to such New Warrant)

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.

          (d) In the event of a sale of substantially all the assets of the
Company or a merger or consolidation of the Company with or into any other
entity (other than a merger the sole purpose of which is to change the state of
incorporation of the Company) or a dissolution or the adoption of a plan of
liquidation of the Company, this Warrant shall terminate on the effective date
of such sale, merger, consolidation, dissolution or adoption (the "Effective
                                                                   ---------

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, and the Company shall not be required to issue or cause to be issued
or deliver or cause to be delivered the certificates for Warrant Shares unless
or until the person or persons requesting the issuance thereof shall have paid
to the Company the amount of such tax or shall have established to the
satisfaction of the Company that such tax has been paid. 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.

     5.  Replacement of Warrant. If this Warrant is mutilated, lost, stolen or
         ----------------------                                               
destroyed, the Company may in its discretion 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 reasonably 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.

     6.  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


                                       3
<PAGE>
 
exercise of this entire Warrant, free from preemptive rights or any other actual
contingent purchase rights of persons other than the Holders (taking into
account the adjustments and restrictions of Section 7). 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.

     7.  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 7. Upon each such adjustment of the Exercise
Price pursuant to this Section 7, 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 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 or otherwise make a distribution or distributions on
shares of its Common Stock (as defined below), (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, then the
Holder shall have the right thereafter to exercise this Warrant only into the
shares of stock and other securities of the Company and property receivable upon
or deemed to be held by holders of Common Stock following such reclassification,
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. The terms of any such reclassification 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 8(b) upon any exercise
following any such reclassification.

          (c) For the purposes of this Section 7, 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


                                       4
<PAGE>
 
          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 7 shall be made to the nearest
cent or the nearest 1/100th of a share, as the case may be.

               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 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, or any compulsory share exchange whereby
               the Common Stock is converted into other securities, cash or
               property of the Company or any third party; 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
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; provided, however, that the failure to mail such notice or any defect
       --------- -------

action required to be specified in such notice.

         -----------------                                                     
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 so presented. If any fraction of a
Warrant Share would, except for the provisions of this Section 8, be issuable on
the exercise of this Warrant, the Company shall, at its option, (i) pay an
amount in cash equal to the Exercise Price multiplied by such fraction or (ii)
round the number of Warrant Shares issuable, up to the next whole number.

     9.  Notices. Any and all notices or other communications or deliveries
         -------

          (a) The Company shall serve as warrant agent under this Warrant. Upon
thirty (30) days' notice to the Holder, the Company may appoint a new warrant
agent (the "New Warrant Agent").
            ------------------- 

          (b) Any corporation into which any New Warrant Agent may be merged or

parties hereto and their respective successors and permitted assigns. This
Warrant may be amended only in writing signed by the Company and the Holder.

                            Term of Preferred Stock

          Section 1.     Designation, Amount and Par Value.  The series of 
                         ---------------------------------
preferred stock shall be designated as 4% Series B Convertible Preferred Stock 
(the "Preferred Stock") and the number of shares so designated shall be 300 
      ---------------
(which shall not be subject to increase without the consent of the holders of 
the Preferred Stock (each, a "Holder" and collectively, the "Holders")). Each
                              ------                         -------
share of Preferred Stock shall have a par value of $.01 and a stated value of 
$10,000 (the "Stated Value").
              ------------

          Section 2.     Dividends.
                         ---------

          (a)  Holders shall be entitled to receive, when and as declared by the
Board of Directors out of funds legally available therefor, and the Company 
shall pay, cumulative dividends at the rate per share (as a percentage of the 
Stated Value per share) of 4% per annum, payable, subject to the provisions of 
this Section 2(a), on a quarterly basis on March 31, June 30, September 30 and 
December 31 of each year while such share is outstanding (each a "Dividend 
                                                                  --------
Payment Date") and on each Conversion Date (as defined herein) for such share, 
- ------------
commencing on the earlier to occur of the Conversion Date for such share and 
June 30, 1999, in cash or shares of Common Stock (as defined in Section 8). 
Subject to the terms and conditions herein, the decision whether to pay 
dividends hereunder in Common Stock or cash shall be at the discretion of the 
Company. Dividends on the Preferred Stock shall be calculated on the basis of a 
360-day year, shall accrue daily commencing on the Original Issue Date (as 
defined in Section 8), and shall be deemed to accrue from such date whether or 
not earned or declared and whether or not there are profits, surplus or other 
funds of the Company legally available for the payment of dividends, unless the 
Company provides the Holder with an unqualified legal opinion of its outside 
counsel (both of which legal opinion and counsel are acceptable to the Holder) 
that the accrual of any such dividend (as opposed to payment) is not permitted 
at such time under the General Corporation Law of the State of Delaware. A party
that holds shares of Preferred Stock on the record date with respect to a 
Dividend Payment Date will be entitled to receive such dividend payment and any 
other accrued and unpaid dividends which accrued prior to such Dividend Payment 
Date, without regard to any sale or disposition of such Preferred Stock 
subsequent to the applicable record date. Except as otherwise provided herein, 
if at any time the Company pays less than the total amount of dividends then
accrued on account of the Preferred Stock, such payment shall be distributed
ratably among the Holders based upon the number of shares of Preferred Stock
held by each Holder. If the Company is permitted hereunder to pay dividends in
shares of Common Stock, then the number of shares of Common Stock issuable on
account of such dividend shall equal the cash amount of such dividend on either
the Dividend Payment Date or the Conversion Date, as applicable, divided by the
Conversion Price (as defined herein) on such date. Any dividends to be paid in
cash hereunder that are not paid within three (3) Trading Days (as defined in
Section 8) following a Conversion Date or Dividend Payment Date, as applicable,
shall continue to accrue and shall entail a late fee, which must be paid in
cash, at the rate of 18% per annum (such fees to accrue daily, from the date
such dividend is due hereunder through and including the date of payment). The
Company shall provide the Holders written notice of its intention to pay
dividends in cash or shares of Common Stock not less than ten (10) days prior to
any Dividend Payment Date for so long as shares of Preferred Stock are
outstanding (the Company may indicate in such notice the maximum amount of cash
dividends that it intends to pay during such period). Failure to timely provide
such notice shall be deemed an election by the Company to pay dividends for such
period in shares of Common Stock pursuant to the terms hereof.

          (b)  Notwithstanding anything to the contrary contained herein, the 
Company may not

<PAGE>
 
issue shares of Common Stock in payment of dividends on the Preferred Stock (and
must deliver cash in respect thereof, subject to the provisions of Section 2(a)
with respect to applicable law) if:

               (i)    the number of shares of Common Stock at the time 
authorized, unissued and unreserved for all purposes is insufficient to pay such
dividends in shares of Common Stock;

               (ii)   after the Dividend Effectiveness Date (as defined in 
Section 8), such shares (x) are not registered for resale pursuant to an 
effective Underlying Securities Registration Statement (as defined in Section 
8), or (y) may not be sold without volume restrictions pursuant to Rule 144 
promulgated under the Securities Act (as defined in Section 8), as determined by
counsel to the Company pursuant to a written opinion letter, addressed to the 
Company's transfer agent in the form and substance acceptable to the applicable 
Holder and such transfer agent (if the Company is permitted and elects to pay 
dividends in shares of Common Stock under this clause (ii) prior to the Dividend
Effectiveness Date and thereafter an Underlying Securities Registration 
Statement shall be declared effective by the Commission (as defined in Section 
8), the Company shall, within three (3) Trading Days after the date of such 
declaration of effectiveness, exchange such shares for shares of Common Stock 
that are free of restrictive legends of any kind);

               (iii)  the Company has failed to timely satisfy its conversion 
obligations hereunder; or     
          
               (iv)   the issuance of such shares would result in a violation of
Section 5(a)(iii) or the rules of the Nasdaq Stock Market, Inc. or any other 
rules and regulations governing any Subsequent Market (as defined in Section 8) 
on which the Common Stock is then listed or quoted for trading.

          (c)  So long as any Preferred Stock shall remain outstanding, neither 
the Company nor any subsidiary thereof shall redeem, purchase or otherwise 
acquire directly or indirectly any Junior Securities (as defined in Section 8), 
nor shall the Company directly or indirectly pay or declare any dividend or make
any distribution (other than a dividend or distribution described in Section 5 
or dividends due and paid in the ordinary course on preferred stock of the 
Company at such times when the Company is in compliance with its payment and 
other obligations hereunder) upon, nor shall any distribution be made in respect
of, any Junior Securities, nor shall any monies be set aside for or applied to 
the purchase or redemption (through a sinking fund or otherwise) of any Junior 
Securities or shares pari passu with the Preferred Stock.

          Section 3.     Voting Rights.  Except as otherwise provided herein and
                         -------------
as otherwise required by law, the Preferred Stock shall have no voting rights. 
However, so long as any shares of Preferred Stock are outstanding, the Company 
shall not, without the affirmative vote of the Holders of a majority of the 
shares of the Preferred Stock then outstanding, (a) alter or change adversely 
the powers, preferences or rights given to the Preferred Stock or alter or amend
this Certificate of Designation, (b) authorize or create any class of stock 
ranking as to dividends or distribution of assets upon a Liquidation (as defined
in Section 4) senior to or otherwise pari passu with the Preferred Stock, (c) 
amend its certificate of incorporation or other charter documents so as to 
affect adversely any rights of the Holders, (d) increase the authorized number 
of shares of Preferred Stock, or (e) enter into any agreement with respect to 
the foregoing.

          Section 4.     Liquidation.  Upon any liquidation, dissolution or 
                         -----------
winding-up of the Company, whether voluntary or involuntary (a "Liquidation"), 
                                                                -----------
the Holders shall be entitled, subject to the rights of the holders of the 
Company's Series A Convertible Preferred Stock to receive out of the assets of 
the Company, whether such assets are capital or surplus, for each share of 
Preferred Stock an

                                       2
<PAGE>
 
amount equal to the Stated Value plus all due but unpaid dividends per share, 
whether declared or not, before any distribution or payment shall be made to the
holders of any Junior Securities, and if the assets of the Company shall be 
insufficient to pay in full such amounts, then the entire assets to be 
distributed to the Holders shall be distributed among the Holders ratably in 
accordance with the respective amounts that would be payable on such shares if 
all amounts payable thereon were paid in full. A sale, conveyance or 
disposition of all or substantially all of the assets of the Company or the 
effectuation by the Company of a transaction or series of related transactions
in which more than 50% of the voting power of the Company is disposed of, or a
consolidation or merger of the Company with or into any other company or
companies shall not be treated as a Liquidation, but instead shall be subject to
the provisions of Section 5. The Company shall mail written notice of any such
Liquidation, not less than 45 days prior to the payment date stated therein, to
each record Holder.

          Section 5.      Conversion.
                          ----------

          (a)(i) Conversions at Option of Holder. Each share of Preferred Stock 
                 -------------------------------
shall be convertible into shares of Common Stock (subject to the limitations set
forth in Section 5(a)(iii)), at the Conversion Ratio (as defined in Section 8), 
at the option of the Holder at any time and from time to time from and after 
July 28, 1999 (the "Initial Conversion Date"); provided, that, (A) on and after 
                    -----------------------    --------
the Initial Conversion Date, a Holder shall only be entitled to convert up to
25% of the number of shares of Preferred Stock issued to it on the Original
Issue Date, (B) on and after the first month anniversary of the Initial
Conversion Date, a Holder shall only be entitled to convert up to 50% of the
number of shares of Preferred Stock issued to it on the Original Issue Date, on
a cumulative basis, (C) on and after the second month anniversary of the Initial
Conversion Date, a Holder shall only be entitled to convert up to 75% of the
number of shares of Preferred Stock issued to it on the Original Issue Date, on
a cumulative basis and (D) on and after the third month anniversary of the
Initial Conversion Date, a Holder shall be entitled to convert all of the shares
of Preferred Stock originally issued to it on the Original Issue Date. Holders
shall effect conversions by surrendering the certificate or certificates
representing the shares of Preferred Stock to be converted to the Compnay,
together with the form of conversion notice attached hereto as Exhibit A (a
                                                               ---------  
"Conversion Notice"). Each Conversion Notice shall specify the number of shares
 -----------------
of Preferred Stock to be converted and the date on which such conversion is to
be effected, which date may not be prior to the date the Holder delivers such
Conversion Notice by fascimile (the "Conversion Date"). If no Conversion Date
                                      ---------------
is specified in a Conversion Notice, the Conversion Date shall be the date that
the Conversion Notice is deemed delivered hereunder. If the Holder is converting
less than all shares of Preferred Stock represented by the certificate or 
certificates tendered by the Holder with the Conversion Notice, or if a 
conversion hereunder cannot be effected in full for any reason, the Company 
shall promptly deliver to such Holder (in the manner and within the time set 
forth in Section 5(b)) a certificate representing the number of shares of 
Preferred Stock as have not been converted.

          (ii) Automatic Conversion. Subject to the provisions in this 
               --------------------
paragraph, all outstanding shares of Preferred Stock for which conversion
notices have not previously been received or for which redemption has not been
made or required hereunder shall be automatically converted on the third
anniversary of the Original Issue Date for such shares. The conversion
contemplated by this paragraph shall not occur at such time as (a) (1) an
Underlying Securities Registration Statement is not then effective or (2) the
Holder is not permitted to resell Underlying Shares (as defined in Section 8)
pursuant to Rule 144(k) promulgated under the Securities Act, without volume
restrictions, as evidenced by an opinion letter of counsel acceptable to the
Holder and the transfer agent for the Common Stock; (b) there are not sufficient
shares of Common Stock authorized and reserved for issuance upon such
conversion; or (c) the Company is then in default of its covenants and
obligations hereunder or under the Purchase Agreement or Registration Rights
Agreement. Notwithstanding the foregoing, the three-year period for conversion
under this Section shall be extended (on a day-for-day

                                       3
<PAGE>
 
basis) for any Trading Days after the date that the Commission declares
effective an Underlying Securities Registration Statement that the Purchaser is
unable to resell Underlying Shares under an Underlying Securities Registration
Statement due to (a) the Common Stock not being listed for trading on the Nasdaq
National Market (the "NASDAQ") or any Subsequent Market, (b) the failure of such
                      ------
Underlying Securities Registration Statement to remain effective during the
Effectiveness Period (as defined in the Registration Rights Agreement) as to all
Underlying Shares, or (c) the suspension of the Holder's ability to resell
Underlying Shares thereunder. The provisions of Sections 5(a)(iii)(A)(1) and (2)
shall not apply to any automatic conversion pursuant to this Section 5(a)(ii).

               (iii) Certain Conversion Restrictions.
                     -------------------------------

               (A)(1) A Holder may not convert shares of Preferred Stock or 
receive shares of Common Stock as payment of dividends hereunder to the extent 
such conversion or receipt of such dividend payment would result in the Holder 
beneficially owning (as determined in accordance with Section 13(d) of the 
Exchange Act and the rules thereunder) in excess of 4.999% of the then issued
and outstanding shares of Common Stock, including shares insuable upon
conversion of dividends on, the shares of Preferred Stock held by such Holder
after application of this Section. The Holder shall have the sole authority and
obligation to determine whether the restriction contained in this Section
applies and to the extent that the Holder determines that the limitation
contained in this Section applies, the determination of which shares of
Preferred Stock are convertible shall be in the sole discretion of the Holder.
The provisions of this Section may be waived by a Holder (but only as to itself
and not to any other Holder) upon not less than 75 days prior notice to the
Company, Other Holders shall be unaffected by any such waiver.

                  (2)  A Holder may not convert shares of Preferred Stock or
received shares of Common Stock as payment of dividends hereunder to the extent
such conversion or receipt of such dividend payment would result in the Holder
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act (as defined in Section 8) and the rules thereunder) in excess of
9.999% of the then issued and outstanding shares of Common Stock, including
shares issuable upon conversion of, and payment of dividends on, the shares of
Preferred Stock held by such Holder after application of this Section. The
Holder shall have the sole authority and obligation to determine whether the
restriction contained in this Section applies and to the extent that the Holder
determines that the limitation contained in this Section applies, the
determination of which shares of Preferred Stock are convertible shall be in the
sole discretion of the Holder. The provisions of this Section may be waived by a
Holder (but only as to itself and not to any other Holder) upon not less than 75
days prior notice to the Company. Other Holders shall be unaffected by any such
waiver.

               (B)  Notwithstanding anything to the contrary set forth herein, 
the Company shall not be obligated to issue in excess of 1,883,237 shares of 
Common Stock upon conversion of Preferred Stock and payment of dividends 
hereunder, which number of shares shall be subject to adjustment pursuant to 
Sections 5(c)(ii), (iii), and (v) (such number of shares, the "Issuable 
                                                               --------  
Maximum"). The Issuable Maximum equals 19.99% of the number of shares of Common 
- -------
Stock outstanding immediately prior to the Closing. Shares of Common Stock 
issued in respect of liquidated damages hereunder shall not count towards the 
1,883,237 share limit set forth in this paragraph and shall be paid in cash as 
provided herein unless otherwise agreed to by the Holders. If on any Conversion 
Date (A) the Conversion Price then in effect is such that the aggregate number 
of shares of Common Stock that would then be issuable upon conversion in full of
all then outstanding shares of Preferred Stock and as payment of dividends 
thereon in shares of Common Stock, together with any shares of Common Stock 
previously issued upon conversion of shares of Preferred Stock and as payment of
dividends thereon, would equal or exceed the Issuable Maximum, and (B) the 
Company shall not have previously obtained the vote of 
 
                                       4
<PAGE>
 
shareholders (the "Shareholder Approval"), if any, as may be required by the 
                   --------------------
applicable rules and regulations of the Nasdaq Stock Market or other exchange or
market on which the Common Stock is then listed or quoted for trading to approve
the issuance of shares of Common Stock in excess of the Issuable Maximum 
pursuant to the terms hereof, then the Company shall issue to the Holder so 
requesting a conversion a number of shares of Common Stock equal to its pro-rata
share of the Issuable Maximum (determined by reference to the number of shares 
of Preferred Stock issued to all Holders on the Original Issue Date) and, with 
respect to the remainder of the aggregate Stated Value of the shares of 
Preferred Stock then held by such Holder for which a conversion in accordance 
with the Conversion Price would result in an issuance of shares of Common Stock 
in excess of the Issuable Maximum (the "Excess Stated Value"), the converting 
                                        -------------------
Holder shall have the option to require the Company to either (1) obtain the 
Shareholder Approval applicable to such issuance as soon as is possible, but in
any event not later than the 75th day after such request, or (2) pay cash to the
converting Holder in an amount equal to the Mandatory Redemption Amount (as
defined in Section 8) for the Excess Stated Value. If the Company fails to pay
the Mandatory Redemption Amount in full pursuant to this Section within seven
(7) days after the date payable, the Company will pay interest thereon at a rate
of 18% per annum to the converting Holder, accruing daily from the Conversion
Date until such amount, plus all such interest thereon, is paid in full. If the
Company has been requested by the Holders to obtain, and fails to obtain, the
Shareholder Approval by the 75/th/ day after such request, then the Holders
shall have the right to require the Company to perform under, at the sole option
of such Holder, clause (3) of this Section 5(a)(iii)(B). The Company and the
Holders understand and agree that shares of Common Stock issued to and then held
by Holders as a result of conversions of Preferred Stock and as payment of
dividends thereon shall not be entitled to cast votes on any resolution to
obtain Shareholder Approval pursuant hereto.

          (b)(i) Not later than three (3) Trading Days after any Conversion
Date, the Company will deliver to the Holder (i) a certificate or certificates
which shall be free of restrictive legends and trading restrictions (other than
those required by Section 3.1(b) of the Purchase Agreement) representing the
number of shares of Common Stock being acquired upon the conversion of shares of
Preferred Stock (subject to the limitations set forth in Section 5(a)(iii)
hereof), (ii) one or more certificates representing the number of shares of
Preferred Stock not converted, (iii) a bank check in the amount of accrued and
unpaid dividends (if the Company has elected to pay accrued dividends in cash),
and (iv) if the Company has elected and is permitted hereunder to pay accrued
dividends in shares of Common Stock, certificates, which shall be free of
restrictive legends and trading restrictions (other than those required by
Section 3.1(b) of the Purchase Agreement), representing such shares of Common
Stock, provided, however, that the Company shall not be obligated to issue 
       --------  -------
certificates evidencing the shares of Common Stock issuable upon conversion of
any shares of Preferred Stock until certificates evidencing such shares of
Preferred Stock are delivered for conversion to the Company, or the Holder of
such Preferred Stock notifies the Company that such certificates have been lost,
stolen or destroyed and provides a bond (or other adequate security) reasonably
satisfactory to the Company to indemnify the Company from any loss incurred by
it in connection therewith. The Company shall, upon request of the Holder, if
available, use its best efforts to deliver any certificate or certificates
required to be delivered by the Company under this Section electronically
through the Depository Trust Corporation or another established clearing
corporation performing similar functions. If in the case of any Conversion
Notice such certificate or certificates, including for purposes hereof, any
shares of Common Stock to be issued on the Conversion Date on account of accrued
but unpaid dividends hereunder, are not delivered to or as directed by the
applicable Holder by the third (3/rd/) Trading Day after the Conversion Date,
the Holder shall be entitled by written notice of the Company at any time on or
before its receipt of such certificate or certificates thereafter, to rescind
such conversion, in which event the Company shall immediately return the
certificates representing the shares of Preferred Stock tendered for conversion.

                                       5
<PAGE>
 
               (ii) If the Company fails to deliver to the Holder such
certificate or certificates pursuant to Section 5(b)(i), including for purposes
hereof, any shares of Common Stock to be issued on the Conversion Date on
account of accrued but unpaid dividends hereunder, by the third (3rd) Trading
Day after the Conversion Date, the Company shall pay to such Holder, in cash, as
liquidated damages and not as a penalty, $5,000 for each Trading Day after such
third (3rd) Trading Day until such certificates are delivered. Nothing herein
shall limit a Holder's right to pursue actual damages for the Company's failure
to deliver certificates representing shares of Common Stock upon conversion
within the period specified herein and such Holder shall have the right to
pursue all remedies available to it at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief. The
exercise of any such rights shall not prohibit the Holders from seeking to
enforce damages pursuant to any other Section hereof or under applicable law.
Further, if the Company shall not have delivered any cash due in respect of
conversions of Preferred Stock or as payment of dividends thereon by the third
(3rd) Trading Day after the Conversion Date, the Holder may, by notice to the
Company, require the Company to issue shares of Common Stock pursuant to Section
5(c), except that for such purpose the Conversion Price applicable thereto shall
be the lesser of the Conversion Price on the Conversion Date and the Conversion
Price on the date of such Holder demand. Any such shares will be subject to the
provision of this Section.

               (iii) In addition to any other rights available to the Holder, if
the Company fails to deliver to the Holder such certificate or certificates
pursuant to Section 5(b)(i), including for purposes hereof, any shares of Common
Stock to be issued on the Conversion Date on account of accrued but unpaid
dividends hereunder, by the third (3rd) Trading Day after the Conversion Date,
and if after such third (3rd) Trading Day the Holder purchases (in an open
market transaction or otherwise) Common Stock to deliver in satisfaction of a
sale by such Holder of the Underlying Shares which the Holder was entitled to
receive upon such conversion (a "Buy-In"), then the Company shall (A) pay in
                                 -------       
cash to the Holder (in addition to any remedies available to or elected by the
Holder) the amount by which (x) the Holder's total purchase price (including
brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the
product of (1) the aggregate number of shares of Common Stock so purchased
exceeds (y) the product of (1) the aggregate number of shares of Common Stock
that such Holder was entitled to receive from the conversion at issue multiplied
by (2) the market price of the Common Stock at the time of the sale giving rise
to such purchase obligation and (B) at the option of the Holder, either return
the shares of Preferred Stock for which such conversion was not honored or
deliver to such Holder the number of shares of Common Stock that would have been
issued had the Company timely complied with its conversion and delivery
obligations under Section 5(b)(i). For example, if the Holder purchases Common
Stock having a total purchase price of $11,000 to cover a Buy-In with respect to
an attempted conversion of shares of Preferred Stock with respect to which the
market price of the Underlying Shares on the date of Conversion totaled $10,000,
under clause (A) of the immediately preceding sentence the Company shall be
required to pay the Holder $1,000. The Holder shall provide the Company written
notice indicating the amounts payable to the Holder in respect of the Buy-In.
Notwithstanding anything contained herein to the contrary, if a Holder requires
the Company to make payment in respect of a Buy-In for the failure to timely
deliver certificates hereunder and the Company timely pays in full such payment,
the Company shall not be required to pay such Holder liquidated damages under
Section 5(b)(ii) in respect of the certificates resulting in such Buy-In.

        (c)(i) The conversion price for each share of Preferred Stock (the 
"Conversion Price") in effect on any Conversion Date shall be the lesser of (a) 
 ----------------
$4,2703 (the "Fixed Conversion Price") or (b) 88% of the average of the ten (10)
              ----------------------
lowest Per Share Market Values during the thirty (30) Trading Days immediately 
preceding the applicable Conversion Date (which, at the Holder's option, may 
include Trading Days prior to the Initial Conversion Date), provided, that such 
                                                            --------
thirty (30) Trading Day period shall be extended for the number of Trading Days,
if any, during such period in which (A) trading in the Common Stock is suspended
from the NASDAQ or a Subsequent Market on which it is listed for trading

                                       6
<PAGE>
 
prior to such suspension, or (B) after the date declared effective by the 
Commission, the Underlying Securities Registration Statement is now effective, 
or (C) after the date declared effective by the Commission, the Prospectus 
included in the Underlying Securities Registration Statement may not be used by 
the Holder for the resale of Underlying Shares.

          If (a) the Underlying Securities Registration Statement is not filed 
on or prior to the Filing Date (if the Company files such Underlying Securities 
Registration Statement without affording the Holder the opportunity to review 
and comment on the same as required by Section 3(a) of the Registration Rights 
Agreement, the Company shall not be deemed to have satisfied this clause (a)), 
or (b) the Company fails to file with the Commission a request for acceleration 
in accordance with Rule 12d1-2 promulgated under the Securities Exchange Act of 
1934, as amended, within five (5) days of the date that the Company is notified 
(orally or in writing, whichever is earlier) by the Commission that an 
Underlying Securities Registration Statement will not be "reviewed," or not 
subject to further review or comment, or (c) the Underlying Securities 
Registration Statement is not declared effective by the Commission on or prior 
to the Effectiveness Date, or (d) such Underlying Securities Registration 
Statement is filed with and declared effective by the Commission but thereafter 
ceases to be effective as to all Registrable Securities (as defined in the 
Registration Rights Agreement) at any time prior to the expiration of the 
Effectiveness Period without being succeeded within ten (10) days by a 
subsequent Underlying Securities Registration Statement filed with and declared
effective by the Commission, or (e) trading in the Common Stock shall be 
suspended from the NASDAQ or a Subsequent Market for more than three (3) 
Business Days (which need not be consecutive days), (f) the conversion rights of
the Holders are suspended for any reason or (g) an amendment to the Underlying 
Securities Registration Statement is not filed by the Company with the 
Commission within ten (10) days of the Commission's notifying the Company that 
such amendment is required in order for the Underlying Securities Registration 
Statement to be declared effective (if the Company files such amendment 
without affording the Holder the opportunity to review and comment on the same 
as required by Section 3(a) of the Registration Rights Agreement, the Company 
shall not be deemed to have satisfied this clause (g)) (any such failure or 
breach being referred to as an "Event" and for purposes of clauses (a), (c), (f)

the date on which such Event occurs, or for purposes of clause (b) the date on 
which such five (5) day period is exceeded, or for purposes of clauses (d) and 
(g) the date which such 10 day-period is exceeded, or for purposes of clause (e)
the date on which such three (3) Business Day-period is exceeded, being referred
to as "Event Date"), then, on the Event Date and on each monthly anniversary
       ----------
thereof until such time as the applicable Event is cured, the Company shall pay 
to the Holder 2.5% of the aggregate Stated Value of all of the shares of 
Preferred Stock purchased by such Holder under the Purchase Agreement in cash, 
as liquidated damages and not as a penalty. The provisions of this Section are 
not exclusive and shall in no way limit the Company's obligations hereunder.

          (ii) If the Company, at any time while any shares of Preferred Stock 
are outstanding, shall (a) pay a stock dividend or otherwise make a distribution
or distributions of shares of its Junior Securities or pari passu securities 
payable in shares of Common Stock, (b) subdivide outstanding shares of Common 
Stock into a larger number of shares, (c) combine outstanding shares of Common 
Stock into a smaller number of shares, or (d) issue by reclassification and 
exchange of the Common Stock any shares of capital stock of the Company, then 
the Fixed Conversion Price shall be multiplied by a fraction of which the 
numerator shall be the number of shares of Common Stock outstanding before such 
event and of which the denominator shall be the number of shares of Common Stock
outstanding after such event. Any adjustment made pursuant to this Section 
5(c)(ii) 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, combination or re-classification.

               (iii)     If the Company, at any time while any shares of
Preferred Stock are outstanding, shall issue rights, warrants or options to all
holders of Common Stock entitling them to subscribe for or purchase shares of
Common Stock at a price per share less than the Per Share Market Value at the
record date mentioned below, then the Fixed Conversion Price shall be multiplied
by a fraction, the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to the issuance of such rights, warrants or
options, plus the number of shares of Common Stock which the aggregate offering
price of the total number of shares so offered would purchase at such Per Share
Market Value, and the denominator of which shall be the sum of the number of
shares of Common Stock outstanding immediately prior to such issuance plus the
number of shares of Common Stock offered for subscription or purchase. Such
adjustment shall be made whenever such rights or warrants are issued, and shall
become effective immediately after the record date for the determination of
stockholders entitled to receive such rights or warrants. However, upon the
expiration of any right, warrant or option to purchase shares of Common Stock
the issuance of which resulted in an adjustment in the Conversion Price pursuant
to this Section 5(c)(iii), if any such right, warrant or option shall expire and
shall not have been exercised, the Conversion Price shall immediately upon such
expiration shall be recomputed and effective immediately upon such expiration
shall be increased to the price which it would have been (but reflecting any
other adjustments in the Conversion Price made pursuant to the provisions of
this Section 5 upon the issuance of other rights or warrants) had the adjustment
of the Conversion Price made upon the issuance of such rights, warrants, or
options been made on the basis of offering for subscription or purchase only
that number of shares of Common Stock actually purchased upon the exercise of
such rights, warrants or options actually exercised.

               (iv)      If the Company or any subsidiary thereof, as applicable
with respect to Common Stock Equivalents (as defined below), at any time while 
any shares of Preferred Stock are outstanding, shall issue shares of Common 
Stock or rights, warrants, options or other securities or debt that is 
convertible into or exchangeable for shares of Common Stock ("Common Stock 
                                                              ------------
Equivalents"), 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 Original Issue Date, 
entitling any Person to acquire shares of Common Stock at a price per share less
than the Conversion Price, then the Conversion Price shall be multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior to the issuance of such Common Stock or such
Common Stock Equivalents plus the number of shares of Common Stock which the
offering price for such shares of Common Stock or Common Stock Equivalents would
purchase at the Conversion Price, and the denominator of which shall be the sum
of the number of shares of Common Stock outstanding immediately prior to such
issuance plus the number of shares of Common Stock so issued or issuable,
provided, that for purposes hereof, all shares of Common Stock that are issuable
- --------
upon conversion, exercise or exchange of Common Stock Equivalents shall be
deemed outstanding immediately after the issuance of such Common Stock
Equivalents. Such adjustment shall be made whenever such Common Stock or Common
Stock Equivalents are issued.

               (v)       If the Company, at any time while shares of Preferred 
Stock are outstanding, shall distribute to all holders of Common Stock (and not 
to Holders) evidences of its indebtedness or assets or rights or warrants to 
subscribe for or purchase any security (excluding those referred to in Sections 
5(c)(ii)-(iv) above), then in each such case the Fixed Conversion Price at which
each share of Preferred Stock shall thereafter be convertible shall be 
determined by multiplying the Fixed Conversion 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 Per Share 
Market Value determined as of the record date mentioned above, and of which the 
numerator shall be such Per 

                                       8
<PAGE>
 
Share Market Value on such record date less the then fair market value at such
record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding shares of Common Stock as determined
by the Board of Directors in good faith; provided, however, that in the event of
                                         --------  -------
a distribution exceeding ten percent (10%) of the net assets of the Company, if 
the Holders of a majority in interest of the Preferred Stock dispute such 
valuation, such fair market value shall be determined by a nationally recognized
or major regional investment banking firm or firm of independent certified 
public accountants of recognized standing (which may be the firm that regularly 
examines the financial statements of the Company) (an "Appraiser") selected in 
                                                       ---------
good faith by the Holders of a majority in interest of the shares of Preferred 
Stock then outstanding; and provided, further, that the Company, after receipt 
                            --------  -------
of the determination by such Appraiser shall have the right to select an 
additional Appraiser, in good faith, in which case the fair market value shall 
be equal to the average of the determinations by each such Appraiser. In either 
case the adjustments shall be described in a statement provided to the Holders 
of the portion of assets or evidences of indebtedness so distributed or such 
subscription rights applicable to one share of Common Stock. Such adjustment 
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

                    (vi)    All calculations under this Section 5 shall be made 
to the nearest cent or the nearest 1/100th of a share, as the case may be.

                    (vii)   Whenever the Conversion Price is adjusted pursuant 
to Section 5(o)(ii), (iii), (iv), or (v) the Company shall promptly mail to each
Holder, a notice setting forth the Conversion Price after such adjustment and 
setting forth a brief statement of the facts requiring such adjustment.

                    (viii)  In case of any reclassification of the Common Stock,
or any compulsory share exchange pursuant to which the Common Stock is converted
into other securities, cash or property (other than compulsory share exchanges
which constitute Change of Control Transactions), the Holders of the Preferred
Stock then outstanding shall have the right thereafter to convert such shares
only into the shares of stock and other securities, cash and property receivable
upon or deemed to be held by holders of Common Stock following such
reclassification or share exchange, and the Holders of the Preferred Stock shall
be entitled upon such event to receive such amount of securities, cash or
property as a holder of the number of shares of Common Stock of the Company into
which such shares of Preferred Stock could have been converted immediately prior
to such reclassification or share exchange would have been entitled. This
provision shall similarly apply to successive reclassifications or share
exchanges.

                    (ix)    If (a) the Company shall declare a dividend (or any
other distribution) on the Common Stock, (b) the Company shall declare a special
nonrecurring cash dividend on or a redemption of the Common Stock, (c) the
Company shall authorize the granting to all holders of Common Stock rights or
warrants to subscribe for or purchase any shares of capital stock of any class
or of any rights, (d) the approval of any stockholders of the Company shall be
required in connection with any reclassification of the Common Stock, 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, of any compulsory share
of exchange whereby the Common Stock is converted into other securities, cash or
property, or (e) the Company shall authorize the voluntary or involuntary
dissolution, liquidation or winding up of the affairs of the Company; then the
Company shall cause to be filed at each office or agency maintained for the
purpose of conversion of Preferred Stock, and shall cause to be mailed to the
Holders at their last addresses as they shall appear upon the stock books of the
Company, at least 20 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

                                       9
<PAGE>
 
record is not to be taken, the date as of which the holders of Common Stock of 
record to be 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 Common Stock for 
securities, cash or other property deliverable upon such reclassification, 
consolidation, merger, sale, transfer or share exchange. Holders are entitled to
convert shares of Preferred Stock during the 20-day period commencing the date 
of such notice to the effective date of the event triggering such notice.

          (x)  In case of any (1) merger or consolidated of the Company with or
into another Person that would constitute a Change of Control Transaction, or
(2) sale by the Company of more than one-half of the assets of the Company (on
an as valued basis) in one or a series of related transactions, or (3) tender
or other offer or exchange (whether by the Company or another Person) pursuant
to which holders of Common Stock are permitted to tender or exchange their
shares for other securities, stock, cash or property of the Company or another
Person; then, if a Holder has not exercised its rights of redemption, if any,
under Section 7 hereof, such Holder shall have the right thereafter to (A) if
permitted under Section 7 hereof, exercise its rights of redemption under
Section 7 with respect to such event, (B) convert its shares of Preferred Stock
into the shares of stock and other securities, cash and property receivable upon
or deemed to be held by holders of Common Stock following such merger,
consolidation or sale, and such Holder shall be entitled upon such event or
series of related events to receive such amount of securities, cash and property
as the shares of Common Stock into which such shares of Preferred Stock could
have been converted immediately prior to such merger, consolidation or sales
would have been entitled, (C) in the case of a merger or consolidation, (x)
require the surviving entity to issue shares of convertible preferred stock or
convertible debentures with such aggregate stated value or in such face amount,
as the case may be, equal to the Stated Value of the shares of Preferred Stock
then held by such Holder, plus all accrued and unpaid dividends and other
amounts owing thereon, which newly issued shares of preferred stock or
debentures shall have terms identical (including with respect to conversion) to
the terms of the Preferred Stock (except, in the case of debentures, as may be
required to reflect the differences between debt and equity) and shall be
entitled to all of the rights and privileges of a Holder of Preferred Stock set
forth herein and the agreements pursuant to which the Preferred Stock was issued
(including, without limitation, as such rights relate to the acquisition,
transferability, registration and listing of such shares of stock other
securities issuable upon conversion thereof), and (y) simultaneously with the
issuance of such convertible preferred stock or convertible debentures, shall
have the right to convert such instrument only into shares of stock and other
securities, cash and property receivable upon or deemed to be held by holders of
Common Stock following such merger or consolidation, or (D) in the event of an
exchange or tender offer or other transaction contemplated by clause (3) of this
Section, tender or exchange its shares of Preferred Stock for such securities,
stock, cash and other property receivable upon or deemed to be held by holders
of Common Stock that have tendered or exchanged their shares of Common Stock
following such tender or exchange, and such Holder shall be entitled upon such
exchange or tender to receive such amount of securities, cash and property as
the shares of Common Stock into which shares of Preferred Stock could have been
converted (taking into account all then accrued and unpaid dividends)
immediately prior to such tender or exchange would have been entitled as would
have been issued. In the case of clause (C), the conversion price applicable for
the newly issued shares of convertible preferred stock or convertible debentures
shall be based upon the amount of securities, cash and property that each share
of Common Stock would receive in such transaction, the Conversion Ratio
immediately prior to the effectiveness or closing date for such transaction and
the Conversion Price stated herein. The terms of any such merger, sale,
consolidation, tender or exchange shall include such terms so as to continue to
give the Holders of Preferred Stock the right to receive the securities, cash
and property set forth in this Section upon any conversion or redemption
following such event. This provision shall similarly apply to successive such

                                      10

events.

          (d)  Upon a conversion hereunder the Company shall not be required to
issue stock certificates representing fractions of shares of Common Stock, but
may if otherwise permitted, make a cash payment in respect of any final fraction
of a share based on the Per Share Market Value at such time. If the Company
elects not, or is unable, to make such a cash payment, the Holder of a share of
Preferred Stock shall be entitled to receive, in lieu of the final fraction of a
share, one whole share of Common Stock.

          (e)  The issuance of certificates for Common Stock on conversion of
Preferred Stock and as payment of dividends in shares of Common Stock shall be
made without charge to the Holders thereof for any documentary stamp or similar
taxes that may be payable in respect of the issue or delivery of such
certificate, provided that the Company shall not be required to pay any tax that
may be payable in respect of any transfer involved in the issuance and delivery
of any such certificate upon conversion in a name other than that of the Holder
of such shares of Preferred Stock so converted.

          (f)  Shares of Preferred Stock converted into Common Stock or redeemed
in accordance with the terms hereof shall be canceled and may not be reissued.

      
          (g)  Any and all notices or other communications or deliveries to be
provided by the Holders of the Preferred Stock hereunder, including, without
limitation, any Conversion Notice, shall be in writing and delivered personally,
by facsimile or sent by a nationally recognized overnight courier service,
addressed to the attention of the Chief Financial Officer of the Company at the
facsimile telephone number or address of the principal place of business of the
Company as set forth in the Purchase Agreement. Any and all notices or other
communications or deliveries to be provided by the Company hereunder shall be in
writing and delivered personally, by facsimile or sent by a nationally
recognized overnight courier service, addressed to each Holder at the facsimile
telephone number or address of such Holder appearing on the books of the
Company, or if no such facsimile telephone number or address appears, at the
principal place of business of the Holder. Any notice or other communication or
deliveries hereunder 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), (ii) the date 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,

                                                                    --------  
Redemption Notice") to the Holders to redeem all or any portion of the shares of
- -----------------
Preferred Stock which have not previously been redeemed, at a price equal to the
Optional Redemption Price (as defined below); provided, that, in order to be
valid an Optional Redemption Notice must have been delivered either (1) Within
three (3) Trading Days after any 90 consecutive Trading Day period during which
the average Per Share Market Value was less than the Fixed Conversion Price or
(ii) within one Trading Day after the Per Share Market Value for two (2)
consecutive Trading Days was less than $1.60. The Company shall not be entitled
to deliver an Optional Redemption Notice after the Effectiveness Date if: (i)
the number of shares of Common Stock at the time authorized, unissued and
unreserved for all purposes is insufficient to satisfy the Company's

                                      11
<PAGE>
 
conversion obligations of all shares of Preferred Stock then outstanding, or
(ii) the Underlying Shares then outstanding are not registered for resale
pursuant to an effective Underlying Securities Registration Statement, or (iii)
the Common Stock is not then listed for trading on the NASDAQ, on a Subsequent
Market or the OTC Bulletin Board. The entire Optional Redemption Price shall be
paid in cash. A Holder may convert (and the Company shall honor such conversions
in accordance with the terms hereof) up to 25% of its shares of Preferred Stock
subject to an Optional Redemption Notice given after the Effectiveness Date,
provided that the Conversion Notice for such shares is delivered within 24 hours
following the receipt by such Holder of such an Optional Redemption Notice.

          (b)  Failure by the Company to pay any portion of the Optional 
Redemption Price by the 6th Trading Day following the date of an Optional 
Redemption Notice shall result in the invalidation ab initio if the unpaid

portion of such optional redemption, and, notwithstanding anything herein to the
contrary, the Company shall thereafter have no further rights to optionally 
redeem any shares of Preferred Stock. In such event, the Company shall, at the 
option of the Holder, either, (i) not later than three (3) Trading Days from 
receipt of Holder's request for such election, return to the Holder all of the 
shares of Preferred Stock for which such Optional Redemption Price has not been 
paid in full (the "Unpaid Redemption Shares") or (ii) convert of all or any 
                   ------------------------
portion of the Unpaid Redemption Shares in which event the Per Share Market 
Value for such shares shall be the lower of the Per Share Market Value 
calculated on the date the Optional Redemption Price was originally due and the 
Per Share Market Value as of the Holder's written demand for conversion. If the 
Holder elects option (ii) above, the Company shall within three (3) Trading Days
of its receipt of such election deliver to the Holder the shares of Common Stock
issuable upon conversion of the Unpaid Redemption Shares subject to such Holder 
conversion demand and otherwise perform its obligations hereunder with respect 
thereto.

          (c)  The "Optional Redemption Price" shall equal the sum of (i) the

Applicable Percentage (as defined below) multiplied by the aggregate Stated 
Value of the shares of Preferred Stock to be redeemed, (ii) all then accrued and
unpaid dividends in respect of such shares of Preferred Stock and (iii) all 
other amounts, costs, expenses and liquidated damages due in respect of such 
shares of Preferred Stock. For the purposes hereof, "Applicable Percentage" 
shall mean (x)(l) for optional redemptions not satisfying the requirements of 
clause (y) of this paragraph, but for which the Optional Redemption Notice meets
the requirements of clause (1) of the first sentence of Section 6(a) and such 
notice is given by October 31, 1999. 110%; and (2) for optional redemptions not 
satisfying the requirements of clause (y) of this paragraph, but for which the 
Optional Redemption Notice meets the requirements of clause (1) of the first 
sentence of Section 6(a) and such notice is given after October 31, 1999,118% 
and (y)(1) if the Optional Redemption Notice is given by October 31, 1999 and is
given within two (2) Trading Days after the second consecutive Trading Day on 
which the Conversion Price is less than $1.60. 110%, and (2) if the Optional 
Redemption NOtice is given after October 31, 1999 and is given within two (2)  
Trading Days after the second consecutive Day on which the Conversion Price is 
less than $1.60, 118%.

     Section 7.     Redemption Upon Triggering Events.
                    ---------------------------------

     Upon the occurrence of a Triggering Event, each Holder shall (in addition
to all other rights may have hereunder or under applicable law), have the right,
exercisable at the sole option of such Holder, to require the Company to redeem
all or a portion of the Preferred Stock then held by such Holder for a
redemption price, in cash, equal to the sum of (i) the Mandatory Redemption
Amount plus (ii) the product of (A) the number of Underlying Shares issued in
respect of conversions or as payment of dividends hereunder and then held by the
Holder and (B) the Per Share Market Value on the date such redemption is
demanded or the date the redemption price hereunder is paid in full, whichever
is greater (such sum, "Redemption Price"). The Redemption Price shall be due and

If the Company fails to pay the redemption price hereunder in full pursuant to 
this Section on the date such amount is due in accordance with this Section, the
Company will pay interest thereon at a rate of 18% per annum, accruing daily 
from such date until the redemption price, plus all such interest thereon, is 
paid in full. For purposes of this Section, a share of Preferred Stock is

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

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
               -------------                                                 
this Warrant. Upon thirty (30) days' notice to the Holder, the Company may
appoint a new warrant agent. Any corporation into which the Company or any new
warrant agent may be merged or any corporation resulting from any consolidation
to which the Company or any new warrant agent shall be a party or any
corporation to which the Company or any new warrant agent transfers
substantially all of its corporate trust or shareholders services business shall
be a successor warrant agent under this Warrant without any further act. Any
such successor warrant agent shall promptly cause notice of its succession as
warrant agent to be mailed (by first class mail, postage prepaid) to the Holder
at the Holder's last address as shown on the Warrant Register.

          14.  Miscellaneous.
               ------------- 

               (a) This Warrant shall be binding on and inure to the benefit of
the parties hereto and their respective successors and assigns. This Warrant may

This Warrant shall inure to the sole and exclusive benefit of the Company and
the Holder.

Upon any exercise of this Warrant, in whole or in part, the holder hereof may
pay the aggregate Exercise Price with respect to the shares of Common Stock for
which this Warrant is then being exercised (collectively, the "EXERCISE SHARES")

Company shall issue to the Holder the number of shares of Warrant Stock
determined as follows:

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

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

               A = the average of the closing sale prices of the Common Stock
               for the thirty (30) trading days immediately prior to (but not
               including) the exercise date.

               B = the Exercise Price.

     For purposes of this Section 2.1, the fair market value of one share of
Common Stock (the "FAIR MARKET VALUE") shall be equal to, at any date, and

     System of the National Association of Securities Dealers, Inc. Automated
     Quotation System ("NASDAQ"), then the Fair Market Value shall be equal to
     the average of the daily closing market prices of the Common Stock over a
     period of 30 consecutive trading days prior to the day on which Fair Market
     Value is being determined. As used in this subparagraph (a), "market price"

                                      -2-
<PAGE>
 
     such trading day shall be the average of the closing prices on such day of
     the Common Stock on all domestic primary national securities exchanges on
     which the Common Stock is then listed, or, if there shall have been no
     sales on any such exchange on such day, the average of the highest bid and
     lowest asked prices on all such exchanges at the end of such day, or if the
     Common Stock shall not be so listed, the average of the representative bid
     and asked prices at the end of such trading day as reported by NASDAQ.

          (b) If the Common Stock is not listed or admitted for trading on any
     national securities exchange or quoted on NASDAQ, then the Fair Market
     Value of one share of Common Stock shall be equal to the fair market value
     of the entire capital equity of the Company taken as a whole, divided by
     the number of shares of Common Stock (on a fully diluted basis) then issued
     (or deemed issued) and outstanding, without premium for control and without
     discount for minority interest or restriction on transfer, as determined by
     the Company's Board of Directors in good faith and set forth in writing to
     FSC within fifteen (15) days after the occurrence of the event which
     requires the valuation, unless FSC shall object in writing within five (5)
     days after receipt of the Board of Directors' determination, in which case
     the Fair Market Value shall be determined (x) by a reputable independent
     appraiser selected by mutual agreement of the Company and FSC and set forth
     in writing to the Company and FSC within thirty (30) days after the
     occurrence of the event which requires the valuation, or (y) (if the
     Company and FSC shall have been unable to agree upon an appraiser within
     ten (10) days after FSC's objection to the Board of Directors'
     determination of Fair Market Value) as the average of the two (2) closest
     appraisals by three (3) reputable independent appraisers, one chosen by the
     Company, one chosen by FSC, and the third selected by the other two (2)
     appraisers, set forth in writing within sixty (60) days after the
     occurrence of the event which requires the valuation.  If the Fair Market
     Value as determined by appraisal pursuant to clause (x) above or by the
     average of the appraisals determined in accordance with clause (y) above,
     as the case may be, is greater than the Fair Market Value determined by the
     Board of Directors, then all expenses of such appraisals shall be paid by
     the Company, and in all other circumstances, such appraisal expenses shall
     be paid by FSC.

     2.2.   Warrant Agent In the event that a bank or trust company shall have
            -------------

own name for the account of the Company or such successor entity as may be
entitled thereto, all amounts otherwise payable to the Company or such
successor, as the case may be, on exercise of this Warrant pursuant to this
Section 2.

     2.3.  Termination. This Warrant shall terminate upon the earliest to occur
           -----------

if (and only to the extent that) such statement or omission was made in reliance
upon written information furnished to such underwriter or the Company in an
instrument duly executed by any such Holder and stated to be specifically for
use in such prospectus. offering circular or other document (or related
registration statement, notification or the like) or any amendment or supplement

respect to any particular

                                      -9-

Registration shall be limited to an amount equal to the net proceeds received by
such Holder from the Registrable Securities sold by such Holder in such
Registration.

     (c)  Indemnification Proceedings. Each party entitled to
          --------------- -----------                        
indemnification pursuant to this Section 3.6 (the "indemnified party")
                                                   -----------------        
shall give notice to the party required to provide indemnification pursuant to
this Section 3.8 (the "indemnifying party") promptly after such
                       ------------------                     
indemnified party acquires actual knowledge of any claim as to which indemnity
may be sought, and shall permit the indemnifying party (at its expense) to
assume the defense of any claim or any litigation resulting therefrom; provided
                                                                       --------
that counsel for the indemnifying party, who shall conduct the defense of such
claim or litigation. shall be acceptable to the indemnified party, and the
indemnified party may participate in such defense at such party's expense; and
provided, further, that the failure by any indemnified party to give notice as
- --------  -------
provided in this paragraph (c) shall not relieve the indemnifying party of its
obligations under this Section 3.6 except to the extent that the failure results
in a failure of actual notice to the indemnifying party and such indemnifying
party is damaged solely as a result of the failure to give notice. No
indemnifying party. in the defense of any such claim or litigation, shall.
except with the consent of each indemnified party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect to such claim or litigation. The
reimbursement required by this Section 3.6 shall be made by periodic payments
during the course of the investigation or defense, as and when bills are
received or expenses incurred.

     3.7. Contribution in Lieu of Indemnification. If the indemnification
          ---------------------------------------                        
provided for in Section 3.6 hereof is unavailable to a party that would have
been an indemnified party under any such Section in respect of any losses,
claims, damages or liabilities (or actions in respect thereof) referred to
therein, then each party that would have been an indemnifying party thereunder
shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims,
damages or liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one
hand and such indemnified party on the other in connection with the statements
or omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof). The relative fault shall be determined by reference
to. among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the indemnifying party or such indemnified
party and the parties' relative intent. knowledge. access to information and
opportunity to correct or prevent such statement or omission. The Company and
each Holder of Registrable Securities agree that it would not be just

and equitable if contribution pursuant to this Section 3.7 were determined by

The amount paid or payable by an indemnified party as a result of the losses.
claims, damages or liabilities (or actions in respect thereof) referred to above
in this Section 3.7 shall include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be

                                      -10-
<PAGE>
 
entitled to contribution from any Person who was not guilty of such fraudulent
misrepresentation. Each Holder's liability hereunder with respect to any
particular Registration shall be limited to an amount equal to the net proceeds
received by such Holder from the Registrable Securities sold by such Holder in
such Registration.

     3.8.  Rule 144 Requirements; Form S-3. The Company will make every effort
           -------------------------------                                    
in good faith to take all steps necessary to ensure that the Company will be
eligible to Register securities on Form S-3 (or any comparable form adopted by
the Commission) and to make publicly available and available to the Holders of
Registrable Securities, pursuant to Rule 144 of the Commission under the
Securities Act ("Rule 144"), such information as shall be necessary to enable
the Holders of Registrable Securities to make sales of Registrable Securities
pursuant to Rule 144. The Company will furnish to any Holder of Registrable
Securities, upon request made by such Holder a written statement signed by the
Company, addressed to such Holder, describing briefly the action the Company has
taken or proposes to take to comply with the current public information
requirements of Rule 144. The Company will, at the request of any Holder of
Registrable Securities, upon receipt from such Holder of a certificate
certifying (a) that such Holder has held such Registrable Securities for a
period of not less than two (2) consecutive years, (b) that such Holder has not
been an affiliate (as defined in Rule 144) of the Company for more than the
ninety (90) preceding days, and (c) as to such other matters as may be necessary
to meet the requirements of Rule 144, remove from the stock certificates
representing such Registrable Securities that portion of any restrictive legend
which relates to the Registration provisions of the Securities Act.

     3.9.  Participation in Underwritten Registrations. No Holder of Registrable
           -------------------------------------------                          
Securities may participate in any underwritten Registration pursuant to this
Section 3 unless such Holder of Registrable Securities (a) agrees to sell such
Holder's securities on the basis provided in any underwriting arrangements
approved by the Persons entitled, under the provisions hereof, to approve such
arrangements, and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required by the terms of such underwriting arrangements. Any Holder of
Registrable Securities to be included in any underwritten Registration shall be
entitled at any time to withdraw such Registrable Securities from such
Registration prior to its effective date in the event that such Holder shall
disapprove of any of the terms of the related underwriting agreement.

     3.10. Miscellaneous.
           ------------- 

           (a) Inconsistent Agreements. The Company has not previously entered

     into, and will not at any time after the date hereof enter into, any
     agreement or contract (whether written or oral) with respect to any of its
     securities which prevents the Company from complying in any respect with
     the registration rights granted by the Company to Holders of Registrable
     Securities hereunder.

          (b)  Amendments and Waivers. The provisions of this Section 3
               ----------------------
     including the provisions of this paragraph (b), may not be amended,
     modified or supplemented, and any waiver or consent to or any departure
     from any of the provisions of this Section 3 may not

                                      -11-
<PAGE>
 
     be given and shall not become or be effective, unless and until (in each
     case) the Company shall have received the prior written consent of the
     Holders of 51% or more of all Registrable Securities for any such
     amendment, modification, supplement, waiver or consent.

           (c)  Term. The agreements of the Company contained in this Section 3,
                ----                                                            
     shall terminate with respect to any particular Registrable Securities when
     such Registrable Securities shall have been effectively Registered under
     the Securities Act or sold pursuant to a Public Sale.

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

     4.1.  Delivery. As soon as practicable after the exercise of this Warrant

     4.2.  Fractional Shares. In the event that the exercise of this Warrant, in

full or in part, results in the issuance of any fractional share of Common
Stock, then in such event the holder of this Warrant shall be entitled to cash

manner as for one share of Common Stock pursuant to Section 2.1 hereof.

5.   ADJUSTMENTS FOR DIVIDENDS, DISTRIBUTIONS AND RECLASSIFICATIONS.
     --------------------------------------------------------------

provided for in Section 7.1 hereof, then and in each such case, the holder of
this Warrant, on the exercise hereof as provided in Section 2 hereof, shall be
entitled to receive, in addition to the number of shares of Common Stock
receivable thereupon, and without payment of any additional consideration

the amount of stock and other securities and property (including cash in the
cases referred to in subsections (b) and (c) of this Section 5) which such
holder would have received prior to or would have held on the date of such
exercise if on the date hereof it had been the holder of record of the number of

6.   ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER. ETC.
     --------------------------------------------------------- 

     6.1.  Certain Adjustments. In case at any time or from time to time, the
           -------------------                                               
Company shall (i) effect a capital reorganization, reclassification or
recapitalization, (ii) consolidate with or merge into any other person, or (iii)
transfer all or substantially all of its properties or assets to any other
person, then in each such case, the holder of this Warrant, on the exercise
hereof as provided in Section 2 hereof at any time after the consummation of
such reorganization, recapitalization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise immediately prior
to such consummation or effective date, the stock and other securities and
property (including cash) to which such holder would have been entitled upon
such consummation (or thereafter as a result of such consummation, including in
connection with any dissolution of the Company) if such holder had so exercised
this Warrant immediately prior thereto, all subject to further adjustment
thereafter as provided in Sections 5 and 7 hereof.

     6.2.  Appointment of Trustee for Warrant Holders Upon Dissolution. In the
           -----------------------------------------------------------        
event of any dissolution of the Company following the transfer of all or
substantially all of its properties or assets, the Company, prior to such
dissolution, shall, at its expense, deliver or cause to be delivered the stock
and other securities and property (including cash, where applicable) receivable

dissolution following any such transfer), as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 8 hereof.

     -------------------------------------------------------------------------
STOCK.
- ----- 

     7.1.  General. If at any time there shall occur any stock split, stock
           -------                                                         
dividend, reverse stock split or other subdivision of the Company's Common Stock
(a "STOCK EVENT"), then the number of shares of Common Stock to be received by
the holder of this Warrant shall be appropriately adjusted such that the
proportion of the number of shares issuable hereunder to the total number of
shares of the Company outstanding (on a fully diluted basis) prior to such Stock
Event is equal to the proportion of the number of shares issuable hereunder
after such Stock Event to the total number of shares of the Company outstanding
(on a fully diluted basis) after such Stock Event. No adjustment to the Exercise
Price shall be made in connection with any adjustment of the number of shares of
Common Stock receivable upon exercise of this Warrant, except that the Exercise
Price shall be proportionately decreased or increased upon the occurrence of any
stock split or other subdivision of the Common Stock.

     7.2.  Other Securities. In case any Other Securities shall have been
           ----------------                                              
issued, or shall then be subject to issue, upon the conversion or exchange of
any stock (or Other Securities) of the Company (or any other issuer of Other
Securities or any other entity referred to in Section 6 hereof) or to
subscription, purchase or other acquisition pursuant to any rights or options
granted by the Company (or such other issuer or person), the holder hereof shall
be entitled to receive upon exercise hereof such amount of Other Securities (in
lieu of or in addition to Common Stock) as is determined in accordance with the
terms hereof, treating all references to Common Stock herein as references to
Other Securities to the extent applicable, and the computations, adjustments and
readjustments provided for in this Section 7 with respect to the Exercise Price
and the number of shares of Common Stock issuable upon exercise of this Warrant
shall be made as nearly as possible in the manner so provided and applied to
determine the amount of Other Securities from time to time receivable on the
exercise of the Warrant, so as to provide the holder of the Warrant with the
benefits intended by this Section 7 and the other provisions of this Warrant.

8.   NO IMPAIRMENT. The Company will not, by amendment of its charter or through
     -------------                                                              
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of the Warrant, but will
at all times in good faith assist in the carrying out of all such terms and in
the taking of all such action as may be necessary or appropriate in order to
protect the rights of the holder of the Warrant against impairment. Without
limiting the generality of the foregoing, the Company (i) will take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and non-assessable shares of stock on the exercise
of the Warrant from time to time outstanding, and (ii) will not transfer all or
substantially all of its properties and assets to any other person (corporate or
otherwise), or consolidate with or merge into any other person or permit any
other person to consolidate with or merge into the Company (if the Company is
not the surviving entity), unless such other person shall expressly assume in
writing and will be bound by all the terms of this Warrant.

9.   CERTIFICATE AS TO ADJUSTMENTS. In each case of any event that may require
     -----------------------------                                            
any adjustment or readjustment in the shares of Common Stock issuable on the
exercise of this Warrant, the Company at its expense will promptly prepare a
certificate setting forth such adjustment or readjustment, or stating the
reasons why no adjustment or readjustment is being made, and showing, in detail,
the facts upon which any such adjustment or readjustment is based, including a
statement of (i) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
issued or sold,(ii) the number of shares of Common Stock then outstanding or
deemed to be outstanding on a fully diluted basis, and (iii) the Exercise Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted and readjusted (if required by Section 7) on account thereof. The
Company will forthwith mail a copy of each such certificate to the holder of the
Warrant, and will, on the written request at any time of any holder of a
Warrant, furnish to such holder a like certificate setting forth the
calculations used to determine such adjustment or readjustment. At its option,
the holder of the Warrant may confirm the adjustment noted on the certificate by
causing such adjustment to be computed by the Company's independent accounting
firm or another independent certified public accountant at the expense of the
Company.

thereof, except to the extent that (a) such enforceability is limited by
bankruptcy, insolvency, reorganization, moratorium or other laws relating to or
affecting

                                      -15-

generally the enforcement of creditors rights, and (b) the availability of the
remedy of specific performance or in injunctive or other equitable relief is
subject to the discretion of the court before which any proceeding therefor may
be brought.

Number Nine Visual Technology Reports Results for the Fourth Quarter and
                                                                           
Full Fiscal Year of 1998

LEXINGTON, Mass., April 1 /PRNewswire/ -- Number Nine Visual Technology
Corporation (Nasdaq: NINE - news) today announced revenues and operating results
                     ----   ----                                                
for its fourth quarter of fiscal 1998 ended Jan. 2, 1999. Revenues for the
fourth quarter of 1998 were $3.1 million, a decrease of 79% from approximately
$14.6 million in the fourth quarter of 1997. Revenues for the twelve months of
1998 were approximately $16.5 million, a decrease of 65% from $47.2 million for
the twelve months of 1997. The Company reported a net loss of approximately $2.9
million, or ($0.30) per share on 9.4 million weighted average common shares
outstanding for tile fourth quarter of 1998 compared to net loss of
approximately $5.4 million or $(0.58) per share on 9.2 million weighted average
common shares outstanding for the fourth quarter of 1997. For the twelve months
of 1998, the net loss was approximately $13.9 million or $(1 .49) per share on
9,3 million weighted average shares outstanding compared to net loss of
approximately $20.8 million or ($2.28) per share on 9.1 million weighted average
shares outstanding for 1997.

The results for both the fourth quarter and twelve months of 1998 continue to be
attributable to the intense pricing environment with our market segment.
However, revenue during the fourth quarter of 1998 began to show improvement on
a sequential basis from the third quarter of 1998, with an increase of 108%. The
increase in revenues was a result of a full quarter's shipment of the Company's
proprietary based Revolution IV as well as December 1998 shipments of our
Digital Flat-Panel Solution Pack. These products, along with our much
anticipated SR9 products, utilizing S3's widely accepted Savage 4, will be
important contributors for Number Nine's efforts to return to profitability
during 1999. Andrew Najda, Number Nine's Chief Executive Officer commented, "Our
operating results should begin to improve with market acceptance of these
products. In particular, much acclaimed Digital Flat- Panel solution pack, (the
Silicon Graphics 1600 SW and Number Nine's Revolution IV graphics accelerator)
has begun to ramp into full production for 1999 and is now widely available.
Additionally, we secured a major design win with one of the top five PC
manufacturers, and is expected to begin shipping and announced during our second
quarter of 1999. These two products will be important in contributing gross
margin for the Company."

Until this business begins to impact our operating results, Number Nine
continues to stress the effective 'managing of our operating expenses and
balance sheet. Our operating expenses for the

   fourth quarter and fiscal 1998 decreased approximately 40% from corresponding
   amounts in 1997. Additionally, during 1998, we reduced our inventory
   investment by approximately 65%. During our First quarter of 1999, we were
   successful in raising $3,000,000 of capital through a placement of 4%
   Convertible Preferred Stock with an investor, and able to secure a new $15
   million secured working capital line from a major commercial bank. These
   transactions will assist our ability to fund planned operations in 1999.
   Additionally, Number Nine is beginning to utilize innovative approaches to
   our business that our customers are demanding. These approaches require lower
   inventory levels, generate higher gross margins and benefit our customers.

   Nadja concluded, "We believe that our new product offerings, additional
   financing, and new business model and should strengthen our competitive
   advantages and help the Company return to profitability during 1999."

ARTICLE 2 - THE REVOLVING CREDIT:

     2-1.  Establishment of Revolving Credit.
           --------------------------------- 

          (a)   The Lender hereby establishes a revolving line of credit (the
"REVOLVING

                                       16
<PAGE>
 
CREDIT") in the Borrower's favor pursuant to which the Lender, subject to, and
in accordance with, this Agreement, shall make loans and advances and otherwise
provide financial accommodations to and for the account of the Borrower as
provided herein. The amount available for borrowing under the Revolving Credit
shall be determined by the Lender by reference to Availability, as determined by
the Lender from time to time.

          (b)  As used herein, the term "AVAILABILITY" refers at any time to the
lesser of (i) or (ii), below:

               (i)  up to:

                    (A)    the Commitment

                    Minus
                    -----

                    (B)    The then unpaid principal balance of the Loan
                           Account.

                    Minus
                    -----

                    (C)    The aggregate amounts then undrawn on all outstanding
                           L/C's, acceptances or any other accommodations issued
                           or incurred, or caused to be issued or incurred, by
                           the Lender for the account and/or the benefit of the
                           Borrower.


               (ii) up to:

                    (A)    Eighty percent (80%) of the face amount of the
                           Borrower's Acceptable Accounts.

                    Plus
                    ----

                    (B)    Eighty percent (80%) of the face amount of the
                           Borrower's Acceptable Foreign Accounts.

                    Minus
                    -----

                    (C)    The Dilution Reserve.

                    Minus
                    -----

                    (D)    The then unpaid principal balance of the Loan
                           Account.

                    Minus
                    -----

                    (E)    The aggregate amounts then undrawn on all outstanding
                           L/C's, acceptances, or any other accommodations
                           issued or incurred, or caused to be issued or
                           incurred, by the Lender for the account and/or the
                           benefit of the Borrower.

          (c)  Availability shall be based upon Borrowing Base Certificates
furnished as

                                       17
<PAGE>
 
provided in Section 54 hereof.

           (d)  The proceeds of borrowings under the Revolving Credit shall be
utilized solely to refinance indebtedness to Marine Midland Bank, to pay
transaction costs, for working capital purposes, and for general corporate
purposes.

     2-2.  Advances in Excess of Availability. The Lender does not have any
           ----------------------------------                              
obligation to make any loan or advance, or otherwise to provide any credit for
the benefit of the Borrower such that the balance of the Loan Account exceeds
the Availability. The making of loans, advances, and credits and the providing
of financial accommodations in excess of the Availability is for the benefit of
the Borrower and does not affect the obligations of the Borrower hereunder; such
loans, advances, credits, and financial accommodations constitute Liabilities.
The making of any such loans, advances, and credits and the providing of
financial accommodations, on any one occasion such that the Availability is
exceeded shall not obligate the Lender to make any such loans, credits, or
advances or to provide any financial accommodation on any other occasion nor to
permit such loans, credits, or advances to remain outstanding.

     2-3.  Risks of Value of Collateral.    The Lender's reference to a given
           ----------------------------                                      
asset in connection with the making of loans, credits, and advances and the
providing of financial accommodations under the Revolving Credit and/or the
monitoring of compliance with the provisions hereof shall not be deemed a
determination by the Lender relative to the actual value of the asset in
question. All risks concerning the collectability of the Borrower's accounts are
and remain upon the Borrower. All Collateral secures the prompt, punctual, and
faithful performance of the Liabilities whether or not relied upon by the Lender
in connection with the making of loans, credits, and advances and the providing
of financial accommodations under the Revolving Credit.

     2-4.  Commitment Fee.
           -------------- 

           (a) As compensation for the Lender's commitment to make loans and
advances to the Borrower and as compensation for the Lender's maintenance of
sufficient funds available for such purpose, the Lender has earned a Commitment
Fee (so referred to herein) of $ 50,000.00.

           (b) The Commitment Fee shall be payable in full at closing.

     2-5.  Unused Line Fee.  In addition to any other fee by the Borrower on
           ----------------                                                 
account of the Revolving Credit, the Borrower shall pay the Lender an Unused
Line Fee (so referred to herein) in arrears, on the first day of each month (and
on the Termination Date). The Unused Line Fee shall be equal to

                                       18
<PAGE>
 
0:375% per annum of the average difference, during the month just ended (or
relevant period with respect to the payment being made on the Termination Date)
between the Commitment and the unpaid principal balance of the Loan Account.


     2-6.  Early Termination Fee.
           --------------------- 

          (a)  In the event that the Termination Date occurs, for any reason,
prior to the Maturity Date, the Borrower shall pay the Lender the Early
Termination Fee (so referred to herein) determined and payable as follows:


               (i)  the sum of $375,000.00, if the Revolving Credit is
                    refinanced by another financial institution.


               (ii) If the Revolving Credit is repaid in conjunction with the
                    sale of a controlling interest in the Borrower, the
                    following Early termination Fees shall apply:


                         (A)  the sum of $375,000.00, if the Revolving Credit is
                              repaid within the first twelve (12) months after
                              the closing date.


                         (B)  the sum of $225,000.00, if the Revolving Credit is
                              repaid after twelve (12) months from the closing
                              date and prior to twenty-four (24) months after
                              the closing date.


                         (C)  the sum of $75,000.00, if the Revolving Credit is
                              repaid after twenty-four (24) months after the
                              closing date.


     2-7  Procedures Under Revolving Credit.
          --------------------------------- 

          (a) The Borrower may request loans and advances under the Revolving
Credit from time to time under, in each instance in accordance with such
procedures as may from time to time be acceptable to the Lender.

          (b) Subject to the provisions of this Agreement, a loan or advance
under the Revolving Credit duly and timely requested by the Borrower shall be

                (i) The Availability will not be exceeded; and

               (ii) The Revolving Credit has not been suspended as provided in
     Section 2-

                                      19
<PAGE>
 
     7(g).

          (c)  (i)    A loan or advance shall be deemed to have been made under
the Revolving Credit upon the charging of the amount of such loan to the Loan
Account.

               (ii)   There shall not be any recourse to, nor liability of, the
Lender on account of any delay in the receipt, and/or any loss, of funds which
constitute a loan or advance under the Revolving Credit, the wire transfer of
which was properly initiated by the Lender in accordance with wire instructions
provided to the Lender by the Borrower.

               (iii)  The Lender may rely on any request for a loan or advance
or financial accommodation which the Lender, in good faith, believes to have
been made by a person duly authorized to act on behalf of the Borrower and may
decline to make any such requested loan or advance or to provide any such
financial accommodation pending the Lender's being furnished with such
documentation concerning that person's authority to act as may be satisfactory
to the Lender.

               (d) A request by the Borrower for any advance under the Revolving
Credit or of the issuance of an L/C or any other accommodations shall be
irrevocable and shall constitute certification by the Borrower and the Borrower
that as of the date of such request, each of the following is true and correct:

                    (i)   There has been no material adverse change in the
     Borrower's financial condition from the most recent financial information
     furnished the Lender pursuant to this Agreement.

                    (ii)  The Borrower is in compliance with, and has not
     breached any of, its covenants contained in this Agreement.

                    (iii) Each representation which is made herein or in any of
     the Loan Documents (defined below) is then true and complete as of and as
     if made on the date of such request.

                    (iv)  No Suspension Event is then extant.

     (e) The Borrower shall immediately become indebted to the Lender for the
amount of each loan under or pursuant to this Agreement when such loan is deemed
to have been made.

     (f) The Lender, without the request of the Borrower, may advance under the
Revolving Credit any amount which the Borrower is obligated to pay to the Lender
or for which the Borrower or the Lender becomes obligated on account of, or in
respect to, any L/C. Such advance shall be made even if such advance would
result in Availability's being exceeded. Such action on the part of the Lender
shall not constitute a waiver of the Lender's rights under Section 2-10(b),
below.

     (g) Upon the occurrence from time to time of any Suspension Event:

          (i) The Lender may suspend the Revolving Credit immediately

                                      20
<PAGE>
 
               (ii) The Lender shall not be obligated, during such suspension,
     to make any loans or advance, or to provide any financial accommodation
     hereunder or to seek the issuance of any L/C.

               (iii)  The Lender may suspend the right of the Borrower to
     request any LIBOR Loan or to convert any Base Margin Loan to a LIBOR
     Loan.


     2-8.  The Loan Account.
           ---------------- 

           (a) An account (hereinafter, the "Loan Account") shall be opened on
the books of the Lender, in which Loan Account a record may be kept of all loans
made by the Lender to the Borrower under or pursuant to the Revolving Credit and
of all payments thereon.

           (b) The Lender may also keep a record (either in the Loan Account or
elsewhere, as the Lender may from time to time elect) of all interest, fees,
service charges, costs, expenses, and other debits owed the Lender on account of
the Liabilities under the Revolving Credit and of all credits against such
amounts so owed.

           (c) All credits against the Liabilities shall be conditional upon
final payment to the Lender of the items giving rise to such credits. The amount
of any item credited against the Liabilities which is charged back against the
Lender for any reason or is not so paid shall be a Liability and shall be added
to the Loan Account, whether or not the item so charged back or not so paid is
returned.

           (d) Except as otherwise provided herein, all fees, service charges,
costs, and expenses for which the Borrower is obligated hereunder are payable on
demand. In the determination of Availability, the Lender may deem fees, service
charges, accrued interest, and other payments as having been advanced under the
Revolving Credit whether or not such amounts are then due and payable.

           (e) The Lender, without the request of the Borrower, may advance
under the Revolving Credit any interest, fee, service charge, or other payment
to which the Lender is entitled from Co-Agents pursuant hereto and may charge
the same to the Loan Account notwithstanding that such amount so advanced may
result in Availability's being exceeded. Such action on the part of the Lender
shall not constitute a waiver of the Lender's rights under Section 2-10(b),
below. Any amount which is added to the principal balance of the Loan Account as
provided in this Subsection shall bear interest at the interest rate applicable
from time to time to the unpaid principal balance of the Loan Account.

           (f) Any statement rendered by the Lender to the Borrower concerning
the Liabilities shall be considered correct and accepted by the Borrower and
shall be conclusively binding upon the Borrower unless the Borrower provides the
Lender with written objection thereto within twenty (20) days from the mailing
of such statement, which written objection shall indicate, with particularity,
the reason for such objection. The Loan Account and the Lender's books and
records concerning the loan

                                      21
<PAGE>
 
arrangement contemplated herein and the Liabilities shall be prima facie
evidence and proof of the items described therein.

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

by a note (hereinafter, the "Revolving Credit Note") in the form of EXHIBIT 2-9,
annexed hereto, executed by the Borrower. Neither the original nor a copy of the
Revolving Credit Note shall be required, however, to establish or prove any
Liability. In the event that the Revolving Credit Note is ever lost, mutilated,
or destroyed, the Borrower shall execute a replacement thereof and deliver such
replacement to the Lender.

pay the Lender that amount, from time to time, which is necessary so that the
principal balance of the Loan Account does not exceed Availability.

            (c) The Borrower shall pay the Lender the net proceeds of (i) sale
of assets not in the ordinary course of business, and (ii) casualty and
condemnation proceeds (except to the extent utilized to replace or repair the
property subject to the casualty). Such net proceeds will be applied to the
Revolving Credit (at the Lender's option, with a corresponding permanent
reduction in the Commitment).

            (d) The Borrower shall repay the then entire unpaid balance of the
Loan Account upon the Termination Date.


     2-11.  Interest.
            -------- 

            (a) Revolving Credit Loans shall initially bear interest at the Base
Rate plus the Applicable Margin and thereafter shall bear interest at the Base
Rate plus the Applicable Margin or the LIBOR Rate plus the Applicable Margin,

with respect to the subject Revolving Credit Loan or as otherwise provided in
this Agreement.

            (b) The Borrower shall pay interest on each Revolving Credit Loan in
arrears on the applicable Interest Payment Date for that Loan.

            (c) Following the occurrence of any Event of Default (and whether or

advances made under the

                                      22
<PAGE>
 
Revolving Credit shall bear interest at the aggregate of the Base Rate plus four
percent (4%) per annum.


     2-12.  Duration of Interest Periods.
            ---------------------------- 
 
            (a) Subject to the limitation described herein, the Borrower shall
have the option to elect an Interest Period to be applicable to a Revolving
Credit Loan by giving notice of such election (a "Renewal I Conversion Notice")
in the form of EXHIBIT 2-12, annexed hereto received no later than 10:00 Boston
time One Business Day before the end of the then applicable Interest Period if
such Loan is to be converted to a Base Margin Loan and Three Business Days
before (and not counting) the end of the then applicable Interest Period if such
Loan is to be continued as, or converted to, a LIBOR Loan; provided, however,
                                                           --------- ------- 
that (a) any Conversion of LIBOR Loans may be made only on the last day of the
respective Interest Period for such Loans, and (b) no loan may be Converted to a
LIBOR Loan when any Default or Event of Default has occurred and is continuing.
Each such Conversion Request shall be by telephone, telecopy, telex or cable, in
each case confirmed immediately in writing in the manner specified for notices
herein, and shall, within the restrictions specified above, specify (i) the date
of such Conversion, (ii) the Loans to be Converted, and (iii) if such Conversion
is to LIBOR Loan the duration of the initial Interest Period for such Loans.
Each Conversion Request with respect to LIBOR Loans shall be irrevocable and
binding on the Borrower.

            (b) If the Lender does not receive a notice of election of, or
conversion to, an Interest Period for a LIBOR Loan pursuant to subsection (a)
within the applicable time limits specified therein, the Borrower shall be
deemed to have elected to convert such Loan in whole into a Base Margin Loan on
the last day of the then current Interest Period with respect thereto.

            (c) The Borrower shall not select, renew, or convert any Revolving
Credit Loan such that there are more than three (3) interest rates applicable to
the Revolving Credit Loans which are LIBOR Loans at any one time.

            (d) LIBOR Loans shall each be in an amount of not less than Five

against any loss or expense incurred by the Lender as a result of such failure
including, without limitation, any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by the Lender to
fund or maintain a LIBOR Loan to be made by the Lender and the compensation as
provided for in Section 2-19, herein.


     2-13.  Changed Circumstances.     In the event that:
            ---------------------                        

                                      23
<PAGE>
 
          (a)  on any day on which the rate for a LIBOR Loan would otherwise be
     set, the Lender shall have determined in good faith (which determination
     shall be final and conclusive) that adequate and fair means do not exist
     for ascertaining either such rate; or

          (b)  at any time the Lender shall have determined in good faith (which
     determination shall be final and conclusive) that:

               (i) the continuation of or conversion of any Revolving Credit
          Loan to a LIBOR Loan has been made impracticable or unlawful by (A)
          the occurrence of a contingency that materially and adversely affects
          the applicable market or (B) compliance by the Lender in good faith
          with any applicable law or governmental regulation, guideline or order
          or interpretation or change thereof by any governmental authority
          charged with the interpretation or administration thereof or with any
          request or directive of any such governmental authority (whether or
          not having the force of law); or

               (ii) the indices on which the interest rates for LIBOR Loan
          shall no longer represent the effective cost to the Lender for U.S.
          dollar deposits in the interbank market for deposits in which it
          regularly participates;

     then, and in any such event, the Lender shall forthwith so notify the
     Borrower thereof Until the Lender notifies the Borrower that the
     circumstances giving rise to such notice no longer apply, the obligation of
     the Lender to make LIBOR Loans of the type affected by such changed
     circumstances or to permit the Borrower to select the affected interest
     rate as otherwise applicable to any Revolving Credit Loans shall be
     suspended. If at the time the Lender so notifies the Borrower, the Borrower
     has previously given the Lender a Renewal/Conversion Notice with respect to
     one or more LIBOR Loans, but such Revolving Credit Loans have not yet gone
     into effect, such notification shall be deemed to be void and the Borrower
     may borrow Revolving Credit Loans which are Base Margin Loans by giving a
     substitute Renewal/Conversion Notice. Upon the expiration of the Interest
     Period for any LIBOR Loan which is outstanding on the date of such
     notification, the amount of such LIBOR Loan shall thereafter constitute a
     Base Margin Loan.


     2-14.  Payments and Prepayments.
            ------------------------

     provided that (1) each partial prepayment shall be in the principal amount
     of $100,000.00 or an integral multiple thereof, (2) if such prepayment is
     on any day other than the last day of the interest Period relating thereto,
     such amount prepaid

                                   24
<PAGE>
 
     shall be accompanied by any additional amounts necessary to compensate the
     Lender for any costs incurred by the Lender in accordance with Section 2-
     19, herein, including any interest or fees payable by the Lender to lenders
     of funds obtained by it in order to make or maintain its LIBOR Loans
     hereunder and (3) any amount prepaid shall be accompanied by accrued
     interest on the principal repaid to the date of payment.

           (c) In the event that at the time of any such prepayment Loans are
     outstanding of more than one type, the amount prepaid shall be applied
     first to any Base Margin Loan prior to application to any LIBOR Loans.

           (d) Any premium due hereunder upon such prepayment shall be due and
     payable upon any prepayment whatsoever, whether voluntary or involuntary,
     to the extent permitted by law, and after acceleration of the unpaid
     principal balance of the Liabilities after the occurrence of an Event of
     Default.


     2-15.  Fees For L/C's. (a) Prior to the issuance of any L/C, the Borrower
            --------------                                                    
shall pay to the Lender a fee on account of such L/C based upon the Lender's
then current fee schedule for like L/C's.

               (b) In addition to the fee to be paid as provided in Subsection
(a), above, the Borrower shall pay to the Lender, on demand, all issuance,
processing, negotiation, amendment, and administrative fees and other amounts on
account of, or in respect to, each L/C.


     2-16. Establishment of Letter of Credit. (a) Upon the written, telephonic,
           ---------------------------------
or electronic request of the Borrower, the Lender agrees to cause the issuance
of L/C's on behalf of the Borrower as provided herein. The Borrower may request
issuance of L/C's in such manner as may from time to time be reasonably
acceptable to the Lender. The Borrower shall execute and deliver to the Lender
such further documents and instruments in connection with any L/C, as the
Lender, in accordance with the Lender's then customary practices with respect to
similar facilities, may reasonably request including, without limitation, the

<PAGE>
 
            (d) Upon the making of any request by or on behalf of the Borrower
for issuance of a L/C, the Borrower shall be deemed to have certified that as of
the date of such request, the representations set forth in Subsections 2-7(d)
(i)-(iv), above, are true and correct and that the Availability which supports
the issuance of the subject L/C arises out of transactions involving the import
shipment of goods.


     2-17.  Effect of Honor of L/C's. The Borrower shall reimburse the Lender
            --------------- --------                                         
for the amount of any honoring of any L/C. Any such honoring which is not so
reimbursed on the Business Day when so honored shall constitute a Revolving
Credit Loan.


     2-18.  Additional Provisions Relating to L/C's. (a) The obligations of the
            ---------------------------------------

     compliance with the instructions of such person or entity.

The Borrower is conclusively deemed to have waived any such claim against the
Lender and its correspondents unless such notice is so timely given.

            (c)  The Borrower will

                 (i)   procure promptly any necessary documentation, permits, or

     documents, goods, or other property have been released to or upon the order
     of the Borrower under a security agreement or trust or bailee receipt) and
     in and to the proceeds of each and all of the foregoing; and

               (ii) if any third party shall have joined in the application for
     the L/C, assigns and transfers to the Lender all right, title and interest

Lender harmless from and against any loss, cost or expense (including loss of
anticipated profits) that the Lender may sustain or incur as a consequence of
(a) default by the Borrower in payment of the principal amount of or any
interest on any LIBOR Loans as and when due and payable, including any such loss
or expense arising from interest or fees payable by the Lender to lenders of
funds obtained by it in order to maintain its LIBOR Loans, (b) default by the
Borrower in making a borrowing or conversion after the Borrower has given (or is
deemed to have given) a Conversion Request, or (c) the making of any payment of

otherwise, including interest or fees payable by the Lender to lenders of funds
obtained by it in order to maintain any such Loans. Such loss shall include,
without limitation, an amount calculated as follows:

          (a) First, the Lender shall determine the amount by which (i) the
total amount of interest which would have otherwise accrued hereunder on each
installment of principal so paid or not borrowed, during the period beginning on
the date of such payment or failure to borrow and ending on the date such
installment would have been due (the "Reemployment Period"), exceeds (ii) the
total amount of interest which would accrue, during the Reemployment Period, on
any readily marketable bond or other obligation of the United States of America
designated by the Lender in its sole discretion at or about the time of such
payment, such bond or other obligation of the United States of America to be in
an amount equal (as

                                       29
<PAGE>
 
nearly as may be) to the amount of principal so paid or not borrowed and to have
a maturity comparable to the Reemployment Period, and the interest to accrue
thereon to take account of amortization of any discount from par or accretion of
premium above par at which the same is selling at the time of designation. Each
sum amount is hereafter referred to as an "Installment Amount".

           (b) Second, each Installment Amount shall be treated as payable as of
the date on which the related principal installment would have been payable by
the Borrower had such principal installment not been prepaid or not borrowed.

           (c) Third, the amount to be paid on each such date shall be the
present value of the Installment Amount determined by discounting the amount
thereof from the date on which such Installment Amount is to be treated as
payable, at the same annual interest rate as that payable upon the bond or other
obligation of the United States of America designated as aforesaid by the
Lender.


     2-20. Computation of Interest and Fees. Interest and all fees payable
           --------------------------------                               
hereunder shall be computed daily on the basis of a year of 360 days and paid
for the actual number of days for which due. If the due date for any payment of
principal is extended by operation of law, interest shall be payable for such
extended time. If any payment required by this Agreement becomes due on a day
that is not a Business Day, such payment may be made on the next succeeding
Business Day, and such extension shall be included in computing interest in
connection with such payment.

     2-21. Overdue Payments. Overdue amounts payable hereunder, under the Note
           ----------------                                                   
shall bear interest from and including the due date thereof until paid, payable
on demand, at a rate per annum equal to the Base Rate plus 4% per annum.

     2-22. Automatic Payment. The Borrower authorizes the Lender to
           -----------------                                       
automatically debit the Borrower's demand deposit accounts with the Lender on
the Interest Payment Date or such other dates when due for all interest, fees,
costs, commissions, service charges and expenses due to the Lender.

     Borrower's industry.

               (ii) Equipment, the acquisition or right to use of which has been

     4-9. Insurance Policies.
          ------------------ 
          (a)  EXHIBIT 4-9, annexed hereto, is a schedule of all insurance
policies owned by the Borrower or under which the Borrower is the named insured.
Each of such policies is in full force and effect. Neither the issuer of any
such policy nor the Borrower is in default or violation of any such policy.

          (b)  The Borrower shall have and maintain at all times insurance
covering such risks, in such amounts, containing such terms, in such form, for
such periods, and written by such companies as may be satisfactory to the
Lender. The coverage reflected on EXHIBIT 4-9 presently satisfies the foregoing
requirements, it being recognized by the Borrower, however, that such

                                       36
<PAGE>
 
requirements may change hereafter to reflect changing circumstances. All
insurance carried by the Borrower shall provide for a minimum of Sixty (60)
days' written notice of cancellation to the Lender and all such insurance which
covers the Collateral shall include an endorsement in favor of the Lender, which
endorsement shall provide that the insurance, to the extent of the Lender's
interest therein, shall not be impaired or invalidated, in whole or in part, by
reason of any act or neglect of the Borrower or by the failure of the Borrower
to comply with any warranty or condition of the policy. In the event of the
failure by the Borrower to maintain insurance as required herein, the Lender, at
its option, may obtain such insurance, provided, however, the Lender's obtaining
of such insurance shall not constitute a cure or waiver of any Event of Default
occasioned by the Borrower's failure to have maintained such insurance. The
Borrower shall furnish to the Lender certificates or other evidence satisfactory
to the Lender regarding compliance by the Borrower with the foregoing insurance
provisions.

           (c)  The Borrower shall advise the Lender of each claim in excess of
$50,000.00 made by the Borrower under any policy of insurance which covers the
Collateral and will permit the Lender, at the Lender's option in each instance,
to the exclusion of the Borrower, to conduct the adjustment of each such claim
(and of all claims following the occurrence of any Suspension Event). The
Borrower hereby appoints the Lender as the Borrower's attorney in fact to
obtain, adjust, settle, and cancel any insurance described in this section and
to endorse in favor of the Lender any and all drafts and other instruments with
respect to such insurance. The within appointment, being coupled with an
interest, is irrevocable until this Agreement is terminated by a written
instrument executed by a duly authorized officer of the Lender. The Lender shall
not be liable on account of any exercise pursuant to said power except for any
exercise in actual willful misconduct and bad faith. The Lender may apply any
proceeds of such insurance against the Liabilities, whether or not such have
matured, in such order of application as the Lender may determine.

     4-10. Licenses. Each license, distributorship, franchise, and similar
           --------

any such license or agreement.

effective Capital Leases. Exhibit 4-6 includes a list of all other presently
effective Leases. Each of such Leases and Capital Leases is in full force and
effect. No party to any such Lease or Capital Lease is in default or violation
of any such Lease or Capital Lease and the Borrower has not received any notice
or threat of cancellation of any such Lease or Capital Lease. The Borrower
hereby authorizes the Lender at any time

                                       37
<PAGE>
 
and from time to time to contact any of the Borrower's landlords in order to
confirm the Borrower's continued compliance with the terms and conditions of the
Lease(s) between the Borrower and that landlord and to discuss such issues,
concerning the Borrower's occupancy under such Lease(s), as the Lender may
determine.

     4-12.  Requirements of Law.  The Borrower is in compliance with, and shall
            -------------------

     reasonable wear and tear and insured casualty excepted).

            (b)  Not suffer or cause the waste or destruction of any material
     part of the Collateral.

            (c)  Not use any of the Collateral in violation of any policy of
     insurance thereon.

            (d)  Not sell, lease, or otherwise dispose of any of the Collateral,
     other than the following:

                 (i)   The sale of Inventory in compliance with this Agreement.

                 (ii)  The disposal of Equipment which is obsolete, worn out, or
     damaged beyond repair, which Equipment is replaced to the extent necessary
     to preserve or improve the operating efficiency of the Borrower.

                 (iii) The turning over to the Lender of all Receipts as
     provided herein.

Revenue Service that there are any deficiencies, assessments, or other amounts
owed with respect to those tax years through and including the Borrower's

EXHIBIT 4-14 no agreement is extant which waives or extends any statute of
limitations applicable to the right of the Internal Revenue Service to assert a
deficiency or make any other claim for or in respect to federal income taxes. No
issue has been raised in any such examination which, by application of similar
principles, reasonably could be expected to result in the assertion of a
deficiency for any fiscal year open for examination, assessment, or claim by the
Internal Revenue Service.

           (b)  The Borrower has not received written notice from the respective
state and

                                       38

local taxing authorities to which the Borrower is subject that there are any
deficiencies, assessments, or other amounts owed for state and local income,
excise, sales, or other taxes with respect to those tax years referenced on
EXHIBIT 4-14, annexed hereto. No agreement is extant which waives or extends any
statute of limitations applicable to the right of any state taxing authority to
assert a deficiency or make any other claim for or in respect to any such state
taxes. No issue has been raised in any such examination which, by application of
similar principles, reasonably could be expected to result in the assertion of a
deficiency for any fiscal year open for examination, assessment, or claim by any
state or local taxing authority.

          (c)  Except as disclosed on said EXHIBIT 4-14, there are no
examinations of or with respect to the Borrower presently being conducted by the
Internal Revenue Service or any other taxing authority.

          (d)  The Borrower has, and hereafter shall: pay, as they become due
and payable, all taxes and unemployment contributions and other charges of any
kind or nature levied, assessed or claimed against the Borrower or the
Collateral by any person or entity whose claim could result in an Encumbrance
upon any asset of the Borrower or by any governmental authority; properly
exercise any trust responsibilities imposed upon the Borrower by reason of
withholding from employees' pay or by reason of the Borrower's receipt of sales
tax or other funds for the account of any third party; timely make all
contributions and other payments as may be required pursuant to any Employee
Benefit Plan now or hereafter established by the Borrower; and timely file all
tax and other returns and other reports with each governmental authority to whom

any taxes, unemployment contributions, and any and all other charges levied or
assessed upon the Borrower or the Collateral by any person or entity or
governmental authority, and make any contributions or other payments on account
of the Borrower's Employee Benefit Plan as the Lender, in the Lender's
discretion may deem necessary or desirable, to protect, maintain, preserve,
collect, or realize upon any or all of the Collateral or the value thereof or
any right or remedy pertaining thereto, provided, however, the Lender's making
of any such payment shall not constitute a cure or waiver of any Event of
Default occasioned by the Borrower's failure to have made such payment.

   4-15.  No Margin Stock.  The Borrower is not engaged in the business of
          ---------------

least seven (7) days prior written notice of the date, time, and place of any
proposed public sale, and of the date after which any private sale or other

notice shall satisfy all requirements for notice to the Borrower which are
imposed under the UCC or other applicable law with respect to the exercise of
the Lender's rights and remedies upon default.

           (d) The Lender may purchase the Collateral, or any portion of it at
any sale held under this Article.

           (e) If any of the Collateral is sold, leased, or otherwise disposed

reduced as a result thereof unless and until payment is finally received thereon
by the Lender.

upon, occupy, and use any premises owned or occupied by the Borrower, and may
exclude the Borrower from such premises or portion thereof as may have been so
entered upon, occupied, or used by the Lender. The Lender shall not be required
to remove any of the Collateral from any such premises upon the Lender's taking
possession thereof, and may render any Collateral unusable to the Borrower. In
no event shall the Lender be liable to the Borrower for use or occupancy by the

            -----------------------------                                   
Lender a royalty free nonexclusive irrevocable license to use, apply, and affix
any trademark, trade name, logo, or the like in which the Borrower now or

discretions of the Lender hereunder (herein, the "LENDER'S RIGHTS AND REMEDIES")
shall be cumulative and not exclusive of any rights or remedies which it would
otherwise have. No delay or omission by the Lender in exercising or enforcing
any of the Lender's Rights and Remedies shall operate as, or constitute, a
waiver thereof. No waiver by the Lender of any Event of Default or of any
default under any other agreement shall operate as a waiver of any other default
hereunder or under any other agreement. No single or partial exercise of any of
the Lender's Rights or Remedies, and no express or implied agreement or
transaction of whatever nature entered into between the Lender and any person,
at any time, shall preclude the other or further exercise of the Lender 's
Rights and Remedies. No waiver by the Lender of any of the Lender's Rights and
Remedies on any one occasion shall be deemed a waiver on any subsequent
occasion, nor shall it be deemed a continuing waiver. All of the Lender's Rights
and Remedies and all of the Lender's rights, remedies, powers, privileges, and
discretions under any other agreement or transaction are cumulative, and not
alternative or exclusive, and may be exercised by the Lender at such time or
times and in such order of preference as the Lender in its sole discretion may
determine. The Lender's Rights and Remedies may be exercised without resort or
regard to any other source of satisfaction of the Liabilities.

obligations hereunder.


     14-3. Severability. Any determination that any provision of this Agreement

dealings shall limit, modify, or otherwise affect the provisions thereof. No
failure by the Lender to give notice to the Borrower of the Borrower's having
failed to observe and comply with any warranty or covenant included in any Loan
Document shall constitute a waiver of such warranty or covenant or the amendment
of the subject Loan Document. No change made by the Lender in the manner by
which Availability is determined shall obligate the Lender to continue to
determine Availability in that manner.

           (b) The Borrower may undertake any action otherwise prohibited

unless executed in writing by or on behalf of the party to be charged with such
modification, amendment, or waiver (and if such party is the Lender, then by a
duly authorized officer thereof). Any modification, amendment, or waiver
provided by the Lender shall be in reliance upon all representations and
warranties theretofore made to the Lender by or on behalf of the Borrower (and

the Liabilities) make each of the waivers included in Section 14-16(b), below,
knowingly, voluntarily, and intentionally, and understands that the Lender, in
entering into the financial arrangements contemplated hereby and in providing
loans and other financial accommodations to or for the account of the Borrower
as provided herein, whether not or in the future, is relying on such waivers.

             (b) THE BORROWER, AND EACH SUCH GUARANTOR, ENDORSER, AND SURETY

     notice, both with respect to the Liabilities and the Collateral.

                 (ii)   Except as otherwise specifically required hereby, the
     right to notice and/or hearing prior to the Lender's exercising of the
     Lender's rights upon default.

                 (iii)  THE RIGHT TO A JURY IN ANY TRIAL OF ANY CASE OR
     CONTROVERSY IN WHICH THE LENDER IS OR BECOMES A PARTY (WHETHER SUCH CASE OR
     CONTROVERSY IS INITIATED BY OR AGAINST THE LENDER OR IN WHICH THE

     hindrance, delay, or restriction (including, without limitation, any
     automatic stay which otherwise might be imposed pursuant to Section 362 of
     the Bankruptcy Code) with respect to any action which the Lender may or may
     become entitled to take hereunder.

                  (v)  Any defense, counterclaim, set-off, recoupment, or other
     basis on which the amount of any Liability, as stated on the books and
     records of the Lender, could be reduced or claimed to be paid otherwise
     than in accordance with the tenor of and written terms of such Liability.

                  (vi) Any claim to consequential, special, or punitive damages.

REVOLVING CREDIT NOTE                                           BankBoston, N.A.
================================================================================


Boston, Massachusetts                                            March ___, 1999


     FOR VALUE RECEIVED, the undersigned, Number Nine Visual Technology
Corporation, a Delaware corporation with its principal executive offices at 18
Hartwell Avenue, Lexington, Massachusetts 02173 (the "BORROWER') promises to pay
to the order of BankBoston, N.A., a national banking association with offices at
100 Federal Street, Boston, Massachusetts 02110 (hereinafter, with any
subsequent holder, the "LENDER") the aggregate unpaid principal balance of loans
and advances made to or for the account of the Borrower pursuant to the
Revolving Credit established pursuant to the Loan and Security Agreement of even
date (as such may be amended hereafter, the "LOAN AGREEMENT") between the Lender
and the Borrower, with interest at the rate and payable in the manner stated
therein.

     This is the "Revolving Credit Note" to which reference is made in the Loan
Agreement and is subject to all terms and provisions thereof. The principal of,
and interest on, this Note shall be payable as provided in the Loan Agreement
and shall be subject to acceleration as provided therein.

     The Lender's books and records concerning loans and advances pursuant to
the Revolving Credit, the accrual of interest thereon, and the repayment of such
loans and advances, shall be prima facie evidence of the indebtedness to the
Lender hereunder.

     No delay or omission by the Lender in exercising or enforcing any of the
Lender's powers, rights, privileges, remedies, or discretions hereunder shall
operate as a waiver thereof on that occasion nor on any other occasion. No
waiver of any default hereunder shall operate as a waiver of any other default
hereunder, nor as a continuing waiver.

     The Borrower, and each endorser and guarantor of this Note, respectively
waives presentment, demand, notice, and protest, and also waives any delay on
the part of the holder hereof. Each assents to any extension or other indulgence
(including, without limitation, the release or substitution of collateral)
permitted by the Lender with respect to this Note and/or any collateral given to
secure this Note or any extension or other indulgence with respect to any other
liability or any collateral given to secure any other liability of the Borrower
or any other person obligated on account of this Note.

     This Note shall be binding upon the Borrower, and each endorser and
guarantor hereof, and upon their respective heirs, successors, assigns, and
representatives, and shall inure to the benefit of the Lender and its
successors, endorsees, and assigns.

     The liabilities of the Borrower, and of any endorser or guarantor of this
Note, are joint and several, provided, however, the release by the Lender of any
one or more such person, endorser or guarantor shall not release any other
person obligated on account of this Note. Each reference in this Note to the
Borrower, any endorser, and any guarantor, is to such person individually and
also to all such persons jointly. No person obligated on account of this Note
may seek contribution from any other person also obligated unless and until all
liabilities, obligations and indebtedness to the Lender of the person from whom
contribution is sought have been satisfied in full.

                                       1
<PAGE>
 
     This Note is delivered to the Lender at the offices of the Lender in
Boston, Massachusetts, shall be governed by the laws of The Commonwealth of
Massachusetts, and shall take effect as a sealed instrument.

     The Borrower makes the following waiver knowingly, voluntarily, and
intentionally, and understands that the Lender in the establishment and
maintenance of Lender's relationship with the Borrower contemplated by the
within Note, is relying thereon. THE BORROWER, TO THE EXTENT ENTITLED THERETO,
WAIVES ANY PRESENT OR FUTURE RIGHT OF THE BORROWER, OR OF ANY GUARANTOR OR
ENDORSER OF THE BORROWER OR OF ANY OTHER PERSON LIABLE TO THE LENDER ON ACCOUNT
OF OR IN RESPECT TO THE LIABILITIES, TO A TRIAL BY JURY IN ANY CASE OR
CONTROVERSY IN WHICH THE LENDER IS OR BECOMES A PARTY (WHETHER SUCH CASE OR
CONTROVERSY IS INITIATED BY OR AGAINST THE LENDER OR IN WHICH THE LENDER IS
JOINED AS A PARTY LITIGANT), WHICH CASE OR CONTROVERSY ARISES OUT OF, OR IS IN
RESPECT TO, ANY RELATIONSHIP AMONGST OR BETWEEN THE BORROWER, ANY SUCH PERSON,
AND THE LENDER.

================================================================================


                                                                  March __, 1999



     ____________________________, (the "LANDLORD") owns real property located
at 18 Hartwell Avenue, Lexington, Massachusetts 02173 (the "LEASED PREMISES"),
which real property the Landlord leases to Number Nine Visual Technology
Corporation a Delaware corporation with offices at 18 Hartwell Avenue,
Lexington, Massachusetts 02173 (the "TENANT"). The Tenant has applied to
BankBoston, N.A. (the "LENDER"), a national banking association with offices at
100 Federal Street, Boston, Massachusetts 02110 to establish a credit facility
in favor of the Tenant, loans and financial accommodations under which will be
secured by all of the Tenant's present and after acquired assets including,
among other things, the Tenant's inventory and equipment (the "COLLATERAL")
located and to be located upon the Leased Premises. In order to induce the
Lender to establish that credit facility, the Landlord hereby represents,
warrants, covenants and agrees as follows:

     1.   The Tenant is not in default under the terms of its lease for other
Leased Premises.

     2.   The Landlord hereby waives any statutory or other lien of the Landlord
against the Collateral.

     3.   In the event the Tenant defaults on any of the Tenant's obligations to
the Lender, the Lender shall have reasonable time in which to repossess the
Collateral from the Leased Premises. The Landlord will cooperate with the Lender
in gaining access to the Leased Premises for the purpose of repossessing said
Collateral or, if requested by the Lender, the Landlord shall permit the Lender,
or its agent or nominee, to dispose of the Collateral on the Leased Premises in
a manner reasonably designed to minimize any interference with any other of
Landlord's tenants.

     4.   To the extent not paid or prepaid by the Tenant, the Lender shall pay
the Landlord a reasonable sum for the use and occupancy of the Leased Premises
(based upon comparable rent for comparable space) from the date on which the
Lender shall have taken possession of the Collateral on the Lease Premises until
the date of the Lender's vacating the Leased Premises, it being understood,
however, that the Lender shall not, thereby, have assumed any of the obligations
of the Borrower to the Landlord.

     5.   Prior to the Landlord's taking any action to evict the Tenant from the
Leased Premises for breach of the lease, the Landlord shall give the Lender not
less than thirty (30) days written notice of such

                                       1
<PAGE>
 
action at the address set forth above, and a reasonable opportunity to preserve,
protect, and liquidate any Collateral on the Leased Premises and, if the Lender
so elects, to cure such breach of the lease.

     6.   The within Agreement shall inure to the benefit of the Lender, its
successors and assigns, shall be binding upon the Landlord, its heirs, assigns,
representatives, and successors.

     Dated this the ____ day of ____ 1999.

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

Dear Mr. Burns,

     This letter will confirm our telephone conversation of March 9, 1999.
During that conversation, we agreed that S3 Incorporated ("S3") intends to pay
two million dollars ($2,000,000) (the "NRE Payment") to Number Nine Visual
Technology Corporation ("Number Nine") in consideration for Number Nine's
engineering efforts necessary for the design and development of the SR9 graphics
accelerator subsystem, incorporating S3's Savage 4 ASIC technology. These
engineering efforts are necessary in order to meet the requirements of our
mutual customer, IBM, who recently awarded us a major design win for this
product. This NRE Payment is contingent upon Number Nine closing its three
million dollar Preferred Stock Placement and Bank Financing Revolver of fifteen
million dollars, by no later than March 31, 1999.

Sincerely,

S3 INCORPORATED

                             YEAR 2000 COMPLIANCE


     The Borrower has conducted an assessment of its internal information
systems to determine the extent of any Year 2000 problem. This assessment
revealed that its principal information systems correctly define the year 2000
and do not require any modification. As a result, the Borrower does not expect
to incur any material costs associated with Year 2000 issues. However, there can
be no assurance that, to date, the Borrower has identified all material Year
2000 issues associated with internal information systems which could have a
material adverse effect on the Borrower's business, financial condition and
results of operations.

     The Borrower is in the process of contacting its customers, suppliers,
financial institutions, creditors, service providers and governmental agencies,
with which the Borrower has a material relationship, in an effort to verify the
Year 2000 readiness of these third parties that could cause a material impact on
the Borrower. However, there can be no assurance that all material Year 2000
issues associated with third parties will be identified and corrected on a
timely basis, or that corrections made by third parties will be compatible with
Borrower's information systems. The Borrower's business, financial condition and
results of operations could be materially adversely affected by the failure of
its systems and applications or those operated by third parties to properly
operate or manage dates beyond 1999.

     The Borrower has not yet designed a contingency plan to address any Year
2000 issues that may arise, partially as a result of the favorable responses
regarding Year 2000 readiness received to date. The Borrower intends to design
and implement such a contingency plan prior to the end of the current fiscal
year, which will be based in part upon the balance of the responses the Borrower
expects to receive. The Borrower expects to identify and resolve all Year 2000
Problems that could materially affect its business operations. However,
management believes that it is not possible to, determine with complete
certainty that all Year 2000 Problems affecting the Borrower have been
identified or corrected. The number of devices that could be affected and the
interactions among these devices are simply too numerous. In addition, the
Borrower cannot accurately predict how many Year 2000 Problem-related failures
will occur or the severity, duration or financial consequences of these perhaps
inevitable and unforeseen failures. As a result, management expects that the
Borrower could likely suffer the following consequences:

     1.   A significant number of operational inconveniences and inefficiencies
for the Borrower and its clients that may divert management's time and
attention, and financial and human resources from its ordinary business
activities and

     2.   A lesser number of serious system failures that may require
significant efforts by the Borrower or its clients to prevent or alleviate
material business disruptions.

     Based on the activities described above, the Borrower does not believe that
the Year 2000 Problem will have a material adverse effect on the Borrower's
business or results of operations.

                                  LITIGATION


1.   On June 11, 1996, a complaint was filed in the United States District Court
for the District of Massachusetts by named plaintiff RBI, an Alaskan limited
partnership, against the Borrower, Andrew Najda and Stanley W. Bialek (the
"Selling Stockholders") and the managing underwriters of the Borrower's initial
public offering, Robertson, Stephens & Company, Cowen & Company and Unterberg
Harris (the "Managing Underwriters"). On or about July 17, 1996, a complaint was
filed in the United States District Court for the District of Massachusetts by
named plaintiff John Foley against the Borrower, each member of the Borrower's
Board of Directors, (Andrew Najda, Stanley W. Bialek, Gill Cogan, Dr. Paul R.
Low, Dr. Fouad H. Nader and William H. Thalheimer), Kevin M. Hanks, former Chief
Financial Officer and Treasurer of the Borrower, and the Managing Underwriters.
On or about October 16, 1996, an additional complaint was filed in the United
States District Court for the District of Massachusetts by named plaintiff
Robert Schoenhofer against the Borrower, each member of the Borrower's Board of
Directors, Mr. Hanks, and the Managing Underwriters. Each of the plaintiffs
purports to represent a class of purchasers of the Common Stock of the Borrower
between and including May 26, 1995 through January 31, 1996. Each complaint
alleges that the named defendants violated the Securities Act of 1933, as
amended, and the Securities Exchange Act of 1934, as amended, by, among other
things, issuing to the investing public false and misleading statements
regarding the Borrower's business, products, sales and earnings during the class
period in question. The plaintiffs seek unspecified damages, interest, costs and
fees. By order of the District Court, these actions have been consolidated into
a single action. It is possible that other claims may be made against the
Borrower or that there may be other consequences from the lawsuits. The
defendants deny any liability, believe they have meritorious defenses, and
intend to vigorously defend these and any similar lawsuits that may be filed,
although the ultimate outcome of these matters cannot yet be determined. If the
lawsuits are not resolved satisfactorily for the Borrower, there could be a
material adverse effect on the Borrower's future financial condition and results
of operations and, accordingly, income (loss). The Borrower does not believe
that the ultimate liability, if any, is estimable or probable, and therefore no
provision for any liability that may result from the actions has been recognized
in the Borrower's consolidated financial statements.

2.   Finnegan, Henderson, Farabow, Garrett & Dunner, L.L.P has sent the Borrower
a letter, dated March 17, 1998, that alleges that the use of the Borrower's
monitors with certain on-screen displays infringes upon the patents referenced
therein.

3.   The Borrower has received demand letters from Micron, Dell, and Unisys in
connection with a countersuit filed by Hakan Lans against Micron which has filed
a complaint for declaratory judgment of patent, invalidity and non-infringement
against Hakan Lans. A motion to amend the complaint in the countersuit has been
filed by counsel to Hakan Lans to include the Borrower as an additional
defendant.

REVOLVING CREDIT NOTE                                           BankBoston, N.A.
================================================================================


Boston, Massachusetts                                             March 31, 1999


     FOR VALUE RECEIVED, the undersigned, Number Nine Visual Technology
Corporation, a Delaware corporation with its principal executive offices at 18
Hartwell Avenue, Lexington, Massachusetts 02173 (the "BORROWER") promises to pay
to the order of BankBoston, N.A., a national banking association with offices at
100 Federal Street, Boston, Massachusetts 02110 (hereinafter, with any
subsequent holder, the "LENDER") the aggregate unpaid principal balance of loans
and advances made to or for the account of the Borrower pursuant to the
Revolving Credit established pursuant to the Loan and Security Agreement of even
date (as such may be amended hereafter, the "LOAN AGREEMENT") between the Lender
and the Borrower, with interest at the rate and payable in the manner stated
therein.

     This is the "Revolving Credit Note" to which reference is made in the Loan
Agreement and is subject to all terms and provisions thereof. The principal of,
and interest on, this Note shall be payable as provided in the Loan Agreement
and shall be subject to acceleration as provided therein.

     The Lender's books and records concerning loans and advances pursuant to
the Revolving Credit, the accrual of interest thereon, and the repayment of such
loans and advances, shall be prima facie evidence of the indebtedness to the
Lender hereunder.

     No delay or omission by the Lender in exercising or enforcing any of the
Lender's powers, rights, privileges, remedies, or discretions hereunder shall
operate as a waiver thereof on that occasion nor on any other occasion. No
waiver of any default hereunder shall operate as a waiver of any other default
hereunder, nor as a continuing waiver.

     The Borrower, and each endorser and guarantor of this Note, respectively
waives presentment, demand, notice, and protest, and also waives any delay on
the part of the holder hereof. Each assents to any extension or other indulgence
(including, without limitation, the release or substitution of collateral)
permitted by the Lender with respect to this Note and/or any collateral given to
secure this Note or any extension or other indulgence with respect to any other
liability or any collateral given to secure any other liability of the Borrower
or any other person obligated on account of this Note.

     This Note shall be binding upon the Borrower, and each endorser and
guarantor hereof, and upon their respective heirs, successors, assigns, and
representatives, and shall inure to the benefit of the Lender and its
successors, endorsees, and assigns.

     The liabilities of the Borrower, and of any endorser or guarantor of this
Note, are joint and several, provided, however, the release by the Lender of any
one or more such person, endorser or guarantor shall not release any other
person obligated on account of this Note. Each reference in this Note to the
Borrower, any endorser, and any guarantor, is to such person individually and
also to all such persons jointly. No person obligated on account of this Note
may seek contribution from any other person also obligated unless and until all
liabilities, obligations and indebtedness to the Lender of the person from whom
contribution is sought have been satisfied in full.

     This Note is delivered to the Lender at the offices of the Lender in
Boston, Massachusetts, shall be governed by the laws of The Commonwealth of
Massachusetts, and shall take effect as a sealed

                                       1

instrument.

     The Borrower makes the following waiver knowingly, voluntarily, and
intentionally and understands that the Lender in the establishment and
maintenance of Lender's relationship with the Borrower contemplated by the
within Note, is relying thereon. THE BORROWER, TO THE EXTENT ENTITLED THERETO,
WAIVES ANY PRESENT OR FUTURE RIGHT OF THE BORROWER, OR OF ANY GUARANTOR OR
ENDORSER OF THE BORROWER OR OF ANY OTHER PERSON LIABLE TO THE LENDER ON ACCOUNT
OF OR IN RESPECT TO THE LIABILITIES, TO A TRIAL BY JURY IN ANY CASE OR
CONTROVERSY IN WHICH THE LENDER IS OR BECOMES A PARTY (WHETHER SUCH CASE OR
CONTROVERSY IS INITIATED BY OR AGAINST THE LENDER OR IN WHICH THE LENDER IS
JOINED AS A PARTY LITIGANT), WHICH CASE OR CONTROVERSY ARISES OUT OF, OR IS IN
RESPECT TO, ANY RELATIONSHIP AMONGST OR BETWEEN THE BORROWER, ANY SUCH PERSON,
AND THE LENDER.
