Item 1.   Security and Issuer.
- -------   --------------------

         This statement relates to the shares of Common Stock,  $0.001 par value
per share (the "Diamond Common Stock"), of Diamond Multimedia  Systems,  Inc., a
Delaware corporation ("Diamond"). The principal executive offices of Diamond are
located at 2880 Junction Avenue,  San Jose,  California  95134.

Item 2.   Identity and Background.
- -------   ------------------------

     This statement is being filed by S3 Incorporated ("S3"). The principal
offices of S3 are located at 2841 Mission College Boulevard, Santa Clara, CA
95054. S3 is principally engaged in the business of supplying multimedia
acceleration hardware and its associated software for the PC market.

Item 3.   Source and Amount of Funds or Other Consideration.
- -------   --------------------------------------------------

     As more fully described in Item 4 of this Statement, Diamond has issued to
S3 three (3) warrants to purchase an aggregate of 4,597,871 shares of Diamond
Common Stock (collectively, the "Diamond Warrants"). The first of those three
warrants entitles S3 to purchase 1,165,501 shares of Diamond Common Stock at an
exercise price of $4.29 per share. The second warrant entitles S3 to purchase
1,196,172 shares of Diamond Common Stock at an exercise price of $4.18 per
share. The third warrant entitles S3 to purchase 2,236,198 shares of Diamond
Common Stock at an exercise price of $4.471875 per share. If S3 were to exercise
the Diamond Warrants in full, the funds required to purchase the shares of
Diamond Common Stock issuable upon such exercise (assuming a cash exercise)
would be approximately $20.0 million. It is currently anticipated that such
funds would be provided from S3's working capital.

Item 4.   Purpose of Transaction.
- -------   -----------------------

     S3 and Diamond entered into a Credit Agreement, dated as of June 10, 1999,
and amended on June 14, 1999 (the "Credit Agreement"), pursuant to which S3
agreed to make three (3) separate loans to Diamond in amounts not exceeding
$20.0 million in the aggregate. One of the conditions precedent to the making of
each of those loans by S3 is that Diamond shall have issued a common stock
purchase warrant to S3. On June 10, 1999 and in connection with the first loan
under the Credit Agreement (in the amount of $5.0 million), Diamond issued to S3
a warrant (the "First Diamond Warrant") to purchase 1,165,501 shares of Diamond
Common Stock at an exercise price of $4.29 per share, subject to certain
adjustments in accordance with Section 6 of the First Diamond Warrant. On June
15, 1999 and in connection with the second loan under the Credit Agreement (in
the amount of $5.0 million), Diamond issued to S3 a warrant (the "Second Diamond
Warrant") to purchase 1,196,172 shares of Diamond Common Stock at an exercise
price of $4.18 per share, subject to certain adjustments in accordance with
Section 6 of the Second Diamond Warrant. On June 21, 1999, Diamond issued to S3
a warrant (the "Third Diamond Warrant") to purchase 2,236,198 shares of Diamond
Common Stock at an exercise price of $4.471875 per share, subject to certain
adjustments in accordance with Section 6 of the Third Diamond Warrant. The First
Diamond Warrant terminates on the later of June 10, 2000 or the date on which
Diamond's indebtedness to S3 under the Credit Agreement is paid in full. The
Second Diamond Warrant terminates on the later of June 15, 2000 or the date on
which Diamond's indebtedness to S3 under the Credit Agreement is paid in full.
As of the date hereof, the Third Diamond Warrant has not become exercisable and
shall only become exercisable upon the occurrence of certain events. The Third
Diamond Warrant terminates on June 21, 2000 or the date on which Diamond's
indebtedness to S3 under the

<PAGE>

CUSIP No. 252714-10-0             Schedule 13D                 Page 6 of 9 Pages


Credit Agreement is paid in full.  Notwithstanding any provisions therein to the
contrary,  each of the First Diamond Warrant, the Second Diamond Warrant and the
Third  Diamond  Warrant  shall  terminate  upon  the   consummation  of  certain
transactions  involving  the  acquisition  of more  than 50% of the  outstanding
voting  securities of S3 or the disposition of all or substantially  all of S3's
assets.  As the holder of the First Diamond Warrant,  the Second Diamond Warrant
and the Third Diamond Warrant, S3 has certain demand and piggyback  registration
rights  with  respect  to the  shares of Diamond  Common  Stock  covered by such
warrants.

     S3 and Diamond entered into an Agreement and Plan of Merger, dated as of
June 21, 1999 (the "Merger Agreement"), with respect to the merger of a
wholly-owned subsidiary of S3 (the "Merger Sub") with and into Diamond as
provided for in the Merger Agreement (the "Merger"). In the Merger, each
outstanding share of Diamond Common Stock will be converted into shares of
common stock, par value $0.0001 per share, of S3 (the "S3 Common Stock") at an
exchange rate equal to 0.52 share of S3 Common Stock for each share of Diamond
Common Stock. As a result of the Merger, Diamond will become a wholly-owned
subsidiary of S3, and Diamond's board of directors will consist of the directors
of Merger Sub immediately prior to the effective time of the Merger.

     Except as described herein and in Item 6 below, neither S3 nor, to the
knowledge of S3, any of its directors or executive officers has any present plan
or proposal which relates to, or could result in, any of the events referred to
in paragraphs (a) through (j), inclusive, of Item 4 of Schedule 13D. However,
subject to S3's obligations under the agreements referred to above, S3 will
continue to review the business of Diamond and may in the future propose that
Diamond take one or more of such actions.

Item 5.   Interest in Securities of Diamond.
- -------   ----------------------------------

     (a) If S3 exercises the First Diamond Warrant, the Second Diamond Warrant
and the Third Diamond Warrant in full (assuming that the Third Diamond Warrant
becomes exercisable), S3 would become a beneficial owner of an aggregate of
4,597,871 shares of Diamond Common Stock. Based on the number of shares of
Diamond Common Stock reported as outstanding as of March 31, 1999, S3 would then
beneficially own approximately 13.0% of the outstanding shares of Diamond Common
Stock.

     (b) If S3 exercises the First Diamond Warrant, the Second Diamond Warrant
and the Third Diamond Warrant in full (assuming that the Third Diamond Warrant

          (ii) Shared power to vote or direct the vote: none;

          (iii) Sole power to dispose or direct the disposition of: 4,597,871
     shares; and

          (iv) Shared power to dispose or direct the disposition of: none.

     As of the date of this filing, neither S3 nor, to the knowledge of S3, any
of its directors or executive officers beneficially owns any shares of Diamond
Common Stock.

     (c) Except as stated in Item 4 above, there have not been any transactions
in the Diamond Common Stock effected by or for the account of S3 or, to the
knowledge of S3, any of its directors or executive officers, during the past 60
days.

     (d) In the event that S3 were to exercise the First Diamond Warrant, the
Second Diamond Warrant and the Third Diamond Warrant in full (assuming that the
Third Diamond Warrant becomes exercisable), no person, other than S3, would have
the right to receive or

the power to direct the receipt of dividends from, or the proceeds from the sale
of, shares of Diamond Common Stock then owned by S3 for its own account.

     (e) Not applicable.

Item 6.   Contracts, Arrangements, Understandings or Relationships With Respect

to the knowledge of S3, any of its directors or executive officers, has any
contracts, arrangements, understandings or relationships (legal or otherwise)
with any person with respect to any securities of Diamond, including, but not
limited to, transfer or voting of any securities of S3, finder's fees, joint
ventures, loan or option arrangements, puts or calls, guarantees of profits,
division of profits or loss or the giving or withholding or proxies.

             ------

         (a)  Loans.  Subject  to  all of  the  terms  and  conditions  of  this
Agreement,  the Lender  agrees to make three loans (the "Loans") to the Borrower
in the aggregate amount not to exceed twenty million dollars  ($20,000,000) each
to be governed by the terms and  conditions  of, and repaid in accordance  with,
this Agreement.  The first Loan, in an amount not to exceed five million dollars
($5,000,000),  will be made upon  satisfaction  of the  conditions  specified in
Section 3.2. The second  Loan,  in an amount not to exceed five million  dollars
($5,000,000),  will  be  made  as  soon  as  reasonably  practicable  after  the
conditions set forth in Section 3.3 have been  satisfied.  The third Loan, in an
amount not to exceed ten million dollars ($10,000,000),  will be made as soon as
reasonably  practicable  after the conditions set forth in Section 3.4 have been
satisfied.  The Lender  shall have no  obligation  to make the second Loan after
July 1, 1999 and the third Loan after  September  30,  1999.  Amounts  repaid in
respect of the Loans (whether repaid when due or prepaid) may not be reborrowed.

         (b) Notes.  Each Loan made by the Lender shall be evidenced by a single
promissory  note of the  Borrower,  such  note to be  substantially  in the form
attached hereto as Exhibit A, dated the date on which such Loan is made, payable
to the order of the Lender and in a principal amount equal to the amount of such
Loan and otherwise duly completed.  On the date on which the Borrower  submits a
Borrowing Request for a Loan, the Borrower shall deliver the Note to the Lender.

         (c) Borrowing  Procedures  for Loan. The Borrower shall give the Lender
written  notice of its request  for the first and second  Loans no later than 11
a.m. on the Business  Day on which the Loan  requested is to be made and two (2)
Business Days' written  notice of its request for the third Loan,  specifying in
each case the  information  required by the form of Borrowing  Request  attached
hereto as Exhibit B. No  Borrowing  Request may be delivered to the Lender after
the date  falling  thirty  (30) days after the  Effective  Date.  Subject to the
Lender's  receipt  of  a  Borrowing  Request,  and  satisfaction  of  the  other
conditions specified in Article 3 hereof on the date requested, the Lender shall
wire transfer the portion of the Loan so requested as specified in the Borrowing
Request.

         2.2  Interest.
              ---------

         (a) Interest Rate. The Obligations shall bear interest from the date of
disbursement  on the unpaid  principal  amount  thereof  until such amount shall
become due and payable (whether upon Maturity,  by Acceleration or otherwise) at
the lesser of the "Prime Rate" or the maximum  permitted by law. Upon  Maturity,
the Loans (or such portion  thereof as has so become due and payable)  shall, to
the extent  permitted by  applicable  law,  bear interest at a rate equal to the
lesser of the Prime Rate plus two  percentage  points  per annum or the  maximum
permitted by law. "Prime Rate" is a per annum rate equal to the rate of interest
published in the "Money Rates"  section of The Wall Street Journal as the "prime
rate" (the "Prime Rate").  The interest rate chargeable  hereunder in respect of
the Loans shall be increased or decreased, as the case may be, without notice or
demand of any kind, upon the  announcement of any change in the Prime Rate. Each
change in the Prime Rate shall be effective hereunder on the first day following
the announcement of such change.

         (b) Payment of Interest.  Interest on the average  daily balance of the
principal outstanding on the Loan shall be payable in arrears on the last day of
each month and on the Final Maturity Date.

         (c) Computation of Interest.  Interest shall be computed for the actual
number  of days  elapsed  on the  basis of a year  consisting  of three  hundred
sixty-five (365) days.

         (d) Excess  Interest.  The contracted for rate of interest of the Loans
contemplated hereby, without

                                      -6-

<PAGE>


limitation, shall consist of the following: (i) the interest rate set forth in
Section 2.1(a), calculated and applied to the principal balance of the
Obligations in accordance with the provisions of this Agreement; (ii) interest
after an Event of Default, calculated and applies to the amount of the
Obligations in accordance with the provisions hereof, and (iii) all Additional
Sums (as herein defined), if any. The Borrower agrees to pay an effective
contracted for rate of interest which is the sum of the above-referenced
elements. The other charges, goods, things in action or any other sums or things
of value paid or payable by Borrower (collectively, the "Additional Sums"),
whether pursuant to this Agreement or any other documents or instruments in any
way pertaining to this lending transaction or otherwise with respect to this
lending transaction, that under any applicable law may be deemed to be interest
with respect to this lending transaction, for the purpose of any applicable law
that may limit the maximum amount of interest to be charged with respect to this
lending transaction, shall be payable by Borrower as, and shall be deemed to be,
additional interest and for such purposes only, the agreed upon and "contracted
for rate of interest" of this lending transaction shall be deemed to be
increased by the rate of interest resulting from the inclusion of the Additional
Sums.

         (e) It is the  intent of the  parties  to comply  the usury laws of the
State of California (the "Applicable Usury Law"). Accordingly, it is agreed that
notwithstanding  any provisions to the contrary in this Agreement,  or in any of
the documents  securing payment hereof or otherwise relating hereto, in no event
shall  this  Agreement  or such  documents  require  the  payment  or permit the
collection of interest in excess of the maximum  contract rate  permitted by the
Applicable Usury Law (the "Maximum  Interest  Rate").  In the event (i) any such
excess of interest  otherwise would be contracted for,  charged or received from
the Borrower or otherwise in connection with the loan evidenced  hereby, or (ii)
the maturity of the Obligations is accelerated in whole or in part, or (iii) all
or  part  of the  Obligations  shall  be  prepaid,  so  that  under  any of such
circumstances  the amount of  interest  contracted  for,  shared or  received in
connection  with the loan evidenced  hereby,  would exceed the Maximum  Interest
Rate,  then in any such event (A) the provisions of this paragraph  shall govern
and control,  (B) neither  Borrower nor any other Person now or hereafter liable
for the payment of the Obligations  shall be obligated to pay the amount of such
interest to the extent that it is in excess of the Maximum  Interest  Rate,  (C)
any such  excess  which may have been  collected  shall be either  applied  as a
credit against the then unpaid  principal  amount of the Obligations or refunded
to the Borrower,  at the Lender's option, and (D) the effective rate of interest
shall be  automatically  reduced to the  Maximum  Interest  Rate.  It is further
agreed,  without  limiting the generality of the  foregoing,  that to the extent
permitted by the Applicable  Usury Law; (x) all  calculations  of interest which
are made for the  purpose of  determining  whether  such rate  would  exceed the
Maximum  Interest Rate shall be made by  amortizing,  prorating,  allocating and
spreading  during  the  period  of the full  stated  term of the loan  evidenced
hereby,  all interest at any time contracted  for,  charged or received from the
Borrower or otherwise in  connection  with such loan:  and (y) in the event that
the effective rate of interest on the loan should at any time exceed the Maximum
Interest Rate, such excess interest that would otherwise have been collected had
there been no ceiling  imposed by the Applicable  Usury Law shall be paid to the
Lender's from time to time, if and when the effective  interest rate on the loan
otherwise  falls below the Maximum  Interest  Rate,  to the extent that interest
paid to the date of calculation does not exceed the Maximum Interest Rate, until
the entire  amount of interest  which would  otherwise  have been  collected had
there been no ceiling imposed by the Applicable Usury Law has been paid in full.
The Borrower  further agrees that should the Maximum  Interest Rate be increased
at any time  hereafter  because of a change in the  Applicable  Usury Law,  such
increases shall apply to all indebtedness  evidenced  hereby  regardless of when
incurred;  but, again to the extent not prohibited by, the Applicable Usury Law,
should  the  Maximum  Interest  Rate be  decreased  because  of a change  in the
Applicable  Usury  Law,  such  decreases  shall  not  apply to the  indebtedness
evidenced hereby regardless of when incurred.

         2.3  Payments of Principal.
              ----------------------

         (a)  Repayment.  The Borrower  shall repay the principal  amount of the
Loan on the Final Maturity Date.

         (b) Prepayment of Loan. The Loans are subject to prepayment as follows:

                                      -7-

<PAGE>

                  (i) The  Borrower may prepay the Loans in part or whole at any
         time without penalty or premium.

                  (ii) The Borrower shall promptly  prepay the interest  accrued
         on and the principal  outstanding of the Loans upon the occurrence of a
         Maturity  Triggering  Event or a sale by the Borrower of  substantially
         all of its assets.

                  (iii) The  Borrower  shall,  to the  extent  permitted  by the
         Existing  Debt,  promptly  prepay  the  interest  accrued  on  and  the
         principal  outstanding  of the Loans from the net cash  proceeds of any
         equity in the Borrower issued thereby or of any  Indebtedness  incurred
         by the Borrower which is subordinate to the Obligations.

         (c) Payments.  All payments of interest on and principal amounts of the
Loans and other  amounts  payable by the Borrower  hereunder  shall be in United
States Dollars,  in immediately  available  funds, to Wells Fargo Bank, 121 Park
Center Plaza, San Jose, CA 95113, ABA Routing No.  121000248,  for credit to the
Lender's  account  No.  4572045219,  not later  than 2:00  p.m.  San  Francisco,
California  time on the date on which such  payment is due.  All (whether or not
scheduled)  payments  received  after 2:00 p.m. San Francisco,  California  time
shall be  considered  to have been  received the next Business Day. The Borrower
shall  give the  Lender  notice  on the date of any  prepayments.  Whenever  any
payment  falls on a day which is not a Business  Day, such payment shall be made
the next  succeeding  Business Day, such  extension of time shall be included in
the computation of interest.  The Lender is hereby  authorized to note the date,
amount and interest  rate of the Loan and each payment of principal and interest
with respect  thereto on the Lender's books and records  (either  manually or by
electronic  entry),   which  notation  shall  be  presumptive  evidence  of  the
information noted absent manifest error.

         (d)  Offset.  In  addition  to and not in  limitation  of all rights of
offset  that the Lender may have under  applicable  law,  the  Lender,  upon the
occurrence and during the continuance of an  Acceleration,  shall have the right
to appropriate and apply to the payment of all Obligations any and all balances,
credits or moneys of the Borrower then or thereafter with the Lender.

Subsidiaries are validly issued,  fully paid and  nonassessable  and, other than
directors' qualifying shares in the case of foreign  Subsidiaries,  are owned by
the Borrower or by a wholly owned  Subsidiary  of the Borrower free and clear of
all Liens except for the Lien in favor of Finova,  and there are no  irrevocable
proxies  with  respect  to such  shares.  Except as set forth in the  Disclosure
Letter and except for the capital stock of its  Subsidiaries,  the Borrower does
not own, directly or indirectly,  any capital stock or other ownership  interest
in any corporation,  partnership,  joint venture,  limited  liability company or
other  entity  which  is  material  to the  business  of the  Borrower  and  its
Subsidiaries,  taken as a  whole.  There  are no  material  restrictions  on the
Borrower to vote the stock of any of its Subsidiaries.

         4.7  Indebtedness.  The  Borrower  is not liable  for any  Indebtedness
except for the Existing Debt and Indebtedness incurred under the Loan Documents.

         4.8  Intellectual Property Rights.

         (a) The  Disclosure  Letter  accurately  lists and describes in summary
form all United  States and foreign  letters  patent and  pending  applications,
patent, trade name and trademark registrations and pending applications, service
mark registrations and pending applications, copyright registrations and pending
applications, those trade names and common law trademarks which are currently in
use by the  Borrower  or any  Subsidiary,  now  owned in whole or in part by the
Borrower or any Subsidiary.

         (b) The  Borrower  or its  Subsidiaries  owns each of the  patents  and
patent applications referred to in the Borrower SEC Documents and, except as set
forth in the Borrower SEC Documents,  (i) to the knowledge of the Borrower, each
of the  Borrower  and  its  Subsidiaries  owns or  possesses,  or  could  obtain
ownership or possession of (on terms not materially  adverse to the consolidated
financial  position,  stockholders'  equity,  or  results of  operations  of the
Borrower and its Subsidiaries  taken as a whole) adequate

                                      -13-

and enforceable rights to use all other Intellectual Property (as defined below)
necessary for the conduct of their businesses, (ii) no claims are pending or, to
the knowledge of the Borrower, threatened that the Borrower or any Subsidiary is
infringing on or otherwise violating the rights of any Person with regard to any
Intellectual Property that, if the subject of an unfavorable decision, ruling or
finding, could reasonably be expected to (or, with respect to any pending patent
litigation, the Borrower does not believe will) have a Material Adverse Effect
and the Borrower knows of no basis therefor, and (iii) to the knowledge of the
Borrower, no person is infringing on or otherwise violating any right of the
Borrower or any Subsidiary with respect to any Intellectual Property owned by or
licensed to the Borrower or any Subsidiary. Except as set forth in the Borrower
SEC Documents, the Borrower has received no notice of potential indemnity claims
from customers based upon a notice of infringement any such customer has
received from a patent owner relating to an assertion of infringement of a
patent other than potential indemnity claims that individually or in the
aggregate would not reasonably be expected to have a Material Adverse Effect.
The Borrower's policy is to require that its employees execute agreements
assigning to the Borrower all rights such employees otherwise would have in
Intellectual Property developed by such employees while in the employ of the
Borrower.

         For purposes of this  Agreement,  "Intellectual  Property"  shall mean,
with  respect  a  Person,  patents,   copyrights,   trademarks  (registered  and
unregistered), service marks, brand names, trade names, and registrations in any
jurisdiction  of,  and  applications  in  any  jurisdiction  to  register,   the
foregoing,   technology,   know-how,   software,   and  tangible  or  intangible
proprietary  information  or  materials  and any  other  trade  secrets  related
thereto.

         4.9 Litigation. Except as disclosed in the Borrower SEC Documents filed
prior to the date hereof, there is no action, suit,  investigation or proceeding
pending  against,  or to the  knowledge  of the Borrower  threatened  against or
affecting,  the Borrower or any of its  Subsidiaries or any of their  respective
properties  before any court or arbitrator or any governmental  body,  agency or
official which would reasonably be expected to have a Material Adverse Effect on
the Borrower.

         4.10  Taxes.  Except  as  set  forth  in  the  Borrower  Balance  Sheet
(including the notes thereto) or as otherwise set forth in the Disclosure Letter
and  except as would  not,  individually  or in the  aggregate,  have a Material
Adverse  Effect on the  Borrower,  (a) all Borrower  Tax Returns  required to be
filed with any taxing  authority  by, or with  respect to, the  Borrower and its
Subsidiaries  have been filed in accordance  with all  applicable  laws; (b) the
Borrower  and its  Subsidiaries  have  timely  paid all  Taxes  shown as due and
payable on the Borrower Tax Returns that have been so filed, and, as of the time
of filing, the Borrower Tax Returns correctly  reflected the facts regarding the
income, business, assets, operations,  activities and the status of the Borrower
and its  Subsidiaries  (other than Taxes which are being contested in good faith
and for which adequate  reserves are reflected on the Borrower  Balance  Sheet);
(c) the Borrower and its Subsidiaries  have made provision for all Taxes payable
by the  Borrower and its  Subsidiaries  for which no Borrower Tax Return has yet
been filed; (d) the charges, accruals and reserves for Taxes with respect to the
Borrower  and its  Subsidiaries  reflected  on the  Borrower  Balance  Sheet are
adequate  under  GAAP to cover the Tax  liabilities  accruing  through  the date
thereof; (e) there is no action, suit,  proceeding,  audit or claim now proposed
or pending against or with respect to the Borrower or any of its Subsidiaries in
respect  of any Tax  where  there  is a  reasonable  possibility  of an  adverse
determination;  and (f) to the  best of the  Borrower's  knowledge  and  belief,
neither the Borrower nor any of its  Subsidiaries  is liable for any Tax imposed
on any entity other than such Person, except as the result of the application of
Treas.  Reg. section  1.1502-6 (and any comparable  provision of the tax laws of
any state,  local or foreign  jurisdiction) to the affiliated group of which the
Borrower is the common  parent.  For purposes of this  Agreement,  "Tax Returns"
shall mean any return,  report,  form or similar statement  required to be filed
with respect to any Tax (including any attached schedules),  including,  without
limitation,  any  information  return,  claim  for  refund,  amended  return  or
declaration of estimated Tax.

         4.11 Title to Property.  The Borrower and each of its  Subsidiaries has
good and marketable title to all of its material properties and assets, free and
clear of all Liens, except for Permitted Liens.

         4.12  Leaseholds.  Neither the Borrower nor any of its Subsidiaries has
given or received notice of any material  default under any material lease under
which the  Borrower or any of its  Subsidiaries  is the lessee of real  property
(each a "Borrower  Lease" and  collectively  the "Borrower  Leases") and, to the
knowledge of the Borrower,  neither the Borrower nor any of its Subsidiaries nor
any other party  thereto is in default in any material  respect under any of the
Borrower  Leases.  All of the Borrower Leases are in full force and effect,  and
are valid, binding and enforceable in accordance with their terms, except (a) as
limited by applicable  bankruptcy,  insolvency,  reorganization,  moratorium and
other  laws of  general  application  affecting  enforcement  of  creditors'  or
lessors'  rights   generally  and  (b)  as  limited  by  laws  relating  to  the
availability  of  specific  performance,  injunctive  relief or other  equitable
remedies. Except as set forth in the Disclosure Letter, neither the Borrower nor
any of its Subsidiaries has leased, subleased, licensed or assigned, as the case
may be, all or any portion of its leasehold interest under any Borrower Lease to
any person.

         4.13  Insurance.   The  insurance  carried  by  the  Borrower  and  its
Subsidiaries  is in such  types  and  amounts  and  covering  such  risks as are
consistent  with  customary  practices  and  standards of  companies  engaged in
businesses and operations similar to those of the Borrower and its Subsidiaries.
Except as would not have a Material  Adverse  Effect on the  Borrower,  all such
insurance  is in full force and effect and none of the  Borrower  nor any of its
Subsidiaries  is in  default  thereunder.  Except as would  not have a  Material
Adverse Effect on the Borrower,  all claims  thereunder have been filed in a due
and timely  fashion.  Except as would not have a Material  Adverse Effect on the
Borrower,  neither the Borrower nor any of its Subsidiaries has been notified in
writing of a refusal of any  material  insurance  coverage  relating to products
liability  (including  renewals of any such products liability  coverage) by any
insurance  carrier to which it has applied for  insurance  during the past three
(3) years.

         4.14 Labor Matters.  There are no controversies pending or, to the best
knowledge of each of the Borrower and its respective  Subsidiaries,  threatened,
between the  Borrower  or any of its  Subsidiaries  and any of their  respective
employees,  which  controversies  have or could reasonably be expected to have a
Material Adverse Effect of the Borrower.  As of the Effective Date,  neither the
Borrower nor any of its  Subsidiaries  is a party to any  collective  bargaining
agreement or other labor union  contract  applicable to persons  employed by the
Borrower or its Subsidiaries  nor does the Borrower or its Subsidiaries  know of
any  activities or proceedings of any labor union to organize any such employees
as of the  Effective  Date which have or could  reasonably be expected to have a
Material  Adverse  Effect  on  the  Borrower  and  its  Subsidiaries.  As of the
Effective  Date,  neither  the  Borrower  nor  any of its  Subsidiaries  has any
knowledge  of any strikes,  slowdowns,  work  stoppages or lockouts,  or threats
thereof,  by or with  respect to any  employees  of the  Borrower  or any of its
Subsidiaries as of the Effective Date which have or could reasonably be expected
to have a Material Adverse Effect on the Borrower and its Subsidiaries.

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

         (a) Prior to the date  hereof,  the  Borrower has provided the Borrower
with a list (set  forth in the  Disclosure  Letter)  identifying  each  material
"employee  benefit  plan," as defined in section  3(3) of ERISA,  each  material
employment,   severance  or  similar  contract,   plan,  arrangement  or  policy
applicable to any director, former director,  employee or former employee of the
Borrower and each material plan or arrangement (written or oral),  providing for
compensation,  bonuses,  profit-sharing,  stock  option or other  stock  related
rights or other forms of incentive or deferred compensation,  vacation benefits,
insurance coverage (including any self-insured arrangements),  health or medical
benefits, disability benefits, workers' compensation,  supplemental unemployment
benefits,   severance  benefits  and   post-employment  or  retirement  benefits
(including  compensation,  pension,  health, medical or life insurance benefits)
which is maintained,  administered  or contributed to by the Borrower and covers
any  employee  or director or former  employee or director of the  Borrower,  or
under which the Borrower has any liability.  Such material plans  (excluding any
such plan that is a "multiemployer  plan," as defined in section 3(37) of ERISA)
are referred to collectively herein as the "Borrower Employee Plans."

         (b)  Except  as set  forth  in the  Disclosure  Letter,  each  Borrower
Employee  Plan has been  maintained  in  compliance  with its terms and with the
requirements  prescribed by any and all statutes,  orders, rules and regulations
(including  but not limited to ERISA and the Code) which are  applicable to such
Plan,  except  where  failure  to so comply  would not,  individually  or in the
aggregate, have a Material Adverse Effect on the Borrower.

         (c) Neither the Borrower nor any affiliate of the Borrower has incurred
a liability  under Title IV of ERISA that has not been satisfied in full, and no
condition  exists that presents a material risk to the Borrower or any affiliate
of the  Borrower  of  incurring  any such  liability  other than  liability  for
premiums due the Pension Benefit Guaranty  Corporation (which premiums have been
paid when due).

         (d) All Borrower Employee Plans that are intended to be qualified under
section  401(a) of the Code have been the  subject  of  determination,  opinion,
notification or advisory letters from the Internal Revenue Service ("IRS") which
the company has made available to the Lender.  Each such letter as the effect of
stating that each such  Borrower  Employee  Plan is qualified and is exempt from
Federal income taxes under section  501(a) of the Code.  The remedial  amendment
period with respect to each such Borrower  Employee Plan has not expired for any
amendment to any such Borrower  Employee Plan that was made on or after the date
of the  application  for the  determination,  opinion,  notification or advisory
letter. No such determination, opinion, notification or advisory letter has been
revoked,  nor has any  event  occurred  since the date of the most  recent  such
letter that would adversely affect its qualification, other than as set forth in
the Disclosure Letter.

         (e)  Except as set  forth in the  Disclosure  Letter,  no  director  or
officer or other employee of the Borrower or any of its Subsidiaries will become
entitled  to any  retirement,  severance  or  similar  benefit  or  enhanced  or
accelerated   benefit  (including  any  acceleration  of  vesting  or  lapse  of
repurchase  rights or  obligations  with respect to any employee stock option or
other benefit under any stock option plan or compensation plan or arrangement of
the Borrower) solely as a result of the transactions contemplated hereby.

         (f) Except as reflected in Disclosure Letter, no Borrower Employee Plan
provides  post-retirement  health and medical,  life or other insurance benefits
for retired  employees  of the Borrower or any of its  Subsidiaries  (other than
benefit coverage  mandated by applicable  statute,  including  benefits provided
pursuant to the  Consolidated  Omnibus  Budget  Reconciliation  Act of 1985,  as
codified in Code section  4980B and ERISA  section 601 et seq.,  as amended from
time to time ("COBRA")).

         (g)  Except as set forth in the  Disclosure  Letter,  there has been no
amendment to, written interpretation or announcement (whether or not written) by
the  Borrower  or any of its  affiliates  relating  to, or  change  in  employee
participation or coverage under, any Borrower Employee Plan which would increase
materially  the expense of  maintaining  such  Borrower  Employee Plan above the
level of the  expense  incurred  in respect  thereof  for the twelve (12) months
ended on the Borrower Balance Sheet Date.

         4.20  Compliance  With  Laws.  Neither  the  Borrower  nor  any  of its
Subsidiaries  is in violation  of, or has since  January 1, 1999  violated,  any

for any violations that, individually or in the aggregate,  would not reasonably
be expected to have a Material Adverse Effect on the Borrower.

in the aggregate,  have not had, and would not reasonably be expected to have, a
Material Adverse Effect on the Borrower,  (a) no notice,  notification,  demand,
request for information, citation, summons, complaint or order has been received

been  assessed  against the Borrower or any of its  Subsidiaries,  in each case,
with respect to any matters relating to or arising out of any Environmental Law;
(b) the Borrower and its  Subsidiaries  are and have been in compliance with all
Environmental  Laws;  and (c) there are no  liabilities  of or  relating  to the
Borrower  or  any  of  its  Subsidiaries  relating  to or  arising  out  of  any
Environmental Law of any kind whatsoever, whether accrued, contingent, absolute,
determined,  determinable  or  otherwise,  and there is no  existing  condition,
situation or set of  circumstances  which could reasonably be expected to result
in such a liability.

         4.22 Year 2000  Compliance.  Except as would not reasonably be expected

during, from and into and between the twentieth and twenty-first centuries,  and
the years 1999 and 2000, including correct processing of leap year data.

any of the other Loan  Documents),  or default in the  performance or observance
(subject to any applicable grace period) of any agreement, covenant or condition
with  respect  to any such  Indebtedness  if the  effect of such  default  is to

holders of any such Indebtedness,  or any trustee or agent for such holders,  to
cause  such  Indebtedness  to  become  due and  payable  prior to its  expressed
maturity or, if such  Indebtedness is a guaranty,  to call upon such guaranty in
advance of nonpayment of the guaranteed indebtedness.

state law, and (i) the petition  commencing the  involuntary  case is not timely
controverted;  or (ii)  the  petition  commencing  the  involuntary  case is not
dismissed within forty-five (45) days of its filing; or (iii) an interim trustee
is appointed to take  possession  of all or a portion of the property  and/or to

provided,  however,  that in any litigation  between the Borrower and the Lender

under this Section 8.6(a).

         (b) Any attempt to inspect,  verify, protect,  collect, sell, liquidate

by such  counsel  or  other  professionals  in any  way or  respect  arising  in

harmless  the  Lender  and  its  directors,  officers,  employees,   Affiliates,

impositions  and  charges  imposed  by  any  Governmental  Authority,   actions,
judgments,  suits,  claims,  costs,  expenses and  disbursements  of any kind or
nature  whatsoever,  whether or not well founded,  meritorious or in meritorious
(including,   without  limitation,  any  expenses  (including  attorneys'  fees)
incurred by any such the Lender  Indemnitee in connection with any investigation
or  administrative  or judicial  proceeding,  whether or not any such the Lender
Indemnitee  shall be  designated  a party  thereto)  which  may be  imposed  on,
incurred by or asserted against such the Lender  Indemnitees by any Person other
than the Lender (whether direct, indirect, consequential or punitive and whether
based  on  any  Governmental   Requirement,   including,   without   limitation,
securities,  environmental and commercial laws and regulations, under common law
or at equitable cause, or on contract or otherwise) in any manner relating to or
arising,  directly  or  indirectly,  out  of  this  Agreement,  any  other  Loan
Documents,  or any act, event or transaction  related or attendant thereto;  the
making of Loans hereunder,  the management of the Loans (including any liability
under federal,  state or local  environmental  laws or regulations),  the use or

Matters");  provided,  however,  that the Borrower shall have no obligation to a
the Lender Indemnitee under this Section 8.7 with respect to Indemnified Matters
to the extent such Indemnified Matters were caused by or resulted from the gross
negligence or willful misconduct of a the Lender Indemnitee.  To the extent that
the  undertaking to indemnify,  pay and hold harmless set forth in the preceding
sentence  may be  unenforceable  because  it is  violative  of any law or public
policy,  the Borrower shall  contribute to the payment and  satisfaction  of all
Indemnified Matters incurred by the Lender Indemnitees the maximum portion which
the  Borrower  is  permitted  to pay and  satisfy  under  applicable  law.  This
indemnification  shall survive repayment by the Borrower of all Loans made under
this Agreement,  and the  termination of this Agreement.  This Section 8.7 shall
apply only if the second Loan is not made.

     THIS FIRST AMENDMENT TO CREDIT AGREEMENT (this "First Amendment"),
dated as of June 14, 1999, by and between DIAMOND MULTIMEDIA SYSTEMS, INC., a

corporation (the "Lender"),

                              W I T N E S S E T H:

     WHEREAS, the Borrower and the Lender are parties to a Credit Agreement,
dated as of June 11, 1999 (the "Credit Agreement") pursuant to which the Lender
has extended certain credit facilities to the Borrower; and

     WHEREAS, the parties desire to amend the Credit Agreement to revise
certain conditions to the funding of the second Loan and the third Loan as set
forth in Sections 3.3 and 3.4 of the Credit Agreement and to make other changes
as more specifically provided for herein:

     NOW, THEREFORE, for good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the parties hereto agree as follows:

     1.  Defined Terms. Unless otherwise specifically defined herein, each
         -------------
term used herein which is defined in the Credit Agreement has the meaning
assigned to such term in the Credit Agreement.

     2.  Amendments.
         ----------

     (a)  Section 3.3(a) of the Credit Agreement is hereby amended to read in
its entirety as follows:

         "(a) Warrant. The Borrower shall have issued a common stock
     purchase warrant on terms satisfactory to the Lender. Nothing in this
     Agreement, however, shall be deemed to imply an obligation for the
     Lender or the Borrower to negotiate the terms of such warrant or for
     the Borrower or Lender to agree as to the terms of such warrant."

     (b)  New Sections 3.4(g), (h) and (i) shall be added after Section 3.4(f)
of the Credit Agreement as follows:

         "(g) Merger Agreement and Warrant. The Borrower shall have
     issued a common stock purchase warrant on terms agreed between the
     Borrower and the Lender and entered into an agreement ("Merger
     Agreement") with the Lender pursuant to which the Borrower will merge

     all of its business and assets to the Lender. Nothing in this
     Agreement, however, shall be deemed to imply an obligation for the
     Lender or the Borrower to negotiate the terms of such warrant or for
     the Borrower or Lender to agree as to the terms of such warrant or to
     enter into any agreement pursuant to which the Borrower will merge
     into, combine its business and assets with or transfer substantially
     all of its business and assets to the Lender.

          (h) Assignment or License of Trademark. The Borrower shall
     have entered into an assignment or license agreement pursuant to which
     the Borrower shall assign or license its rights in a trademark on terms
     to be agreed upon between the Borrower and the Lender. Nothing in this
     Agreement, however, shall be deemed to imply an obligation for the
     Lender or the Borrower to negotiate the terms of such agreement or for
     the Borrower or Lender to agree as to the terms of such agreement.

          (i) Negotiation of a Supply Agreement. The Borrower shall have
     entered into a supply agreement with the Lender upon terms to be agreed
     upon between the Borrower and the Lender. Nothing in this Agreement,
     however, shall be deemed to imply an obligation for the Lender or the
     Borrower to negotiate the terms of such agreement or for the Borrower
     or Lender to agree as to the terms of such agreement."

     (c) The reference to "Tuesday, June 15, 1999" in Line 2 of Section 6.11

shall have received a duly executed counterpart hereof signed by Borrower. This
First Amendment, together with the Credit Agreement, contains the entire and
exclusive agreement of the parties hereto with reference to the matters
discussed herein and therein. This First Amendment supersedes all prior drafts
and communications with respect thereto. This First Amendment may not be amended
except in accordance with the provisions of Section 8.3 of the Credit Agreement.

     5.  Ratification of Credit Agreement. Except as amended hereby, all of
         --------------------------------
the provisions set forth in the Credit Agreement remain in full force and
effect. As of the effective date of this First Amendment, any reference in the
Credit Agreement to "this Agreement" shall mean the Credit Agreement as amended

         ------------
to be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

1.       Exercise of Warrant.
         -------------------

1.1      Duration and Exercise of Warrant.
         --------------------------------

     (a) Cash Exercise. This Warrant may be exercised by the Warrantholder by
(i) the surrender of this Warrant to the Company, with a duly executed Exercise
Form specifying the number of Warrant Shares to be purchased, during normal
business hours on any Business Day during the Exercise Period and (ii) the
delivery of payment to the Company, for the account of the Company, of the
Exercise Price for the number of Warrant Shares specified in the Exercise Form,
(A) by wire transfer of immediately available funds to a bank account specified
by the Company; (B) by certified or bank cashier's check; (C) by cancellation of
indebtedness under the Loan Agreement, or (D) of any other amount due to the
Warrantholder under any other contract (including any purchase order) pursuant
to which the Warrantholder does business with the Company not paid within twenty
(20) days of when due, or as otherwise mutually agreed to between the parties.
The Company agrees that such Warrant Shares shall be deemed to be issued to the
Warrantholder as the record holder of such Warrant Shares as of the close of
business on the date on which this Warrant shall have been surrendered and
payment made for the Warrant Shares as aforesaid. A stock certificate or
certificates for the Warrant Shares specified in the Exercise Form shall be
delivered to the Warrantholder as promptly as practicable. If this Warrant shall
have been exercised only in part, the Company shall, at the time of delivery of
the stock certificate or certificates, deliver to the Warrantholder a new
Warrant evidencing the rights to purchase the remaining Warrant Shares, which
new Warrant shall in all other respects be identical with this Warrant. No
adjustments shall be made on Warrant Shares issuable on the exercise of this
Warrant for any cash dividends paid or payable to holders of record of Common
Stock prior to the date as of which the Warrantholder shall be deemed to be the
record holder of such Warrant Shares.

     (b) Net Issue Exercise. In lieu of exercising this Warrant pursuant to
Section 1.1(a), this Warrant may be exercised by the Warrantholder by the
surrender of this Warrant to the Company, with a duly executed Exercise Form
marked to reflect Net Issue Exercise and specifying the number of Warrant Shares
to be purchased, during normal business hours on any Business Day during the
Exercise Period. The Company agrees that such Warrant Shares shall be deemed to
be issued to the Warrantholder as the record holder of such Warrant Shares as of
the close of business on the date on which this Warrant shall have been
surrendered as aforesaid. Upon such exercise, the Warrantholder shall be
entitled to receive shares equal to the value of this Warrant (or the portion
hereof being exercised) computed as of the date of surrender of this Warrant to
the Company using the following formula:

                  X = Y x (A-B)
                      ---------
                         A

Where    X =      the number of shares of Common Stock to be issued to
                  Warrantholder under this Section 1.1(b);

         Y        = the number of shares of Common Stock  otherwise  purchasable
                  under this Warrant (at the date of such calculation);


                                      -2-


<PAGE>

         A = the fair market  value of one share of Common Stock (at the date of
             such calculation);

         B = the Exercise Price (as adjusted to the date of such calculation).

     (c) Fair Market Value. For purposes of Section 1.1(b) "fair market value"
of one share of Common Stock shall mean:

          (i) the average closing price per share of the Common Stock on the
     principal national securities exchange on which the Common Stock is listed
     or admitted to trading for the ten (10) Trading Day period ending on the
     date of exercise, or,

          (ii) if not listed or traded on any such exchange, the average last
     reported sales price per share of the Common Stock on the Nasdaq National
     Market or The Nasdaq SmallCap Market (collectively, "Nasdaq") for the ten
     (10) Trading Day period ending on the date of exercise, or,

          (iii) if not listed or traded on any such exchange or Nasdaq, the
     average of the mean of the bid and asked prices per share of the Common
     Stock as reported in the OTC Bulletin Board or, if not so reported, in the
     "pink sheets" published by the National Quotation Bureau, Inc. for the ten
     (10) Trading Day period ending on the date of exercise, or,

          (iv) if such quotations are not available, the fair market value per
     share of the Common Stock on the date such notice was received by the
     Company as reasonably determined by the Board of Directors of the Company.

     1.2 Number of Warrant Shares. This Warrant shall entitle the Warrantholder
to purchase 1,165,501 shares of Common Stock.

     1.3 Exercise Price. The Exercise Price shall be equal to $4.29 (the
"Exercise Price"). From and after the issuance of this Warrant, the Exercise
Price shall be adjusted in accordance with Section 6 hereof.

     1.4 Term of Warrant and Exercisability.

     (a) Term of Warrant. This Warrant shall terminate on the later of (i) June
10, 2000; (ii) the date on which the indebtedness of the Company to the
Warrantholder under the Loan Agreement is paid in full; provided, however, that
this Warrant shall terminate upon the consummation of an S3 Acquisition. Nothing
in this Section 1.4(a), however, shall require S3 or Diamond to negotiate or
enter into an agreement providing for the merger of Diamond with S3 (directly or
indirectly), and neither party shall have any liability for failing to do so.
The parties' rights and obligations under Sections 2, 8 and 9 hereof shall
survive the termination of this Warrant.

     (b) Exercisability. This Warrant shall be immediately exercisable, during
the Exercise Period, in whole or in part as to ninety-nine percent (99%) of the
Warrant Shares. This

                                      -3-

<PAGE>

Warrant shall become exercisable, during the Exercise Period, as to the
remaining one percent (1%) of the Warrant Shares upon a Change of Control of
Diamond. Notwithstanding anything to the contrary herein, this Warrant may not
be exercised prior to June 15, 1999.

     1.5 Payment of Taxes. The issuance of certificates for Warrant Shares shall
be made without charge to the Warrantholder for any stock transfer or other
issuance tax in respect thereto; provided, however, that the Warrantholder shall
be required to pay any and all taxes which may be payable in respect of any
transfer involved in the issuance and delivery of any certificate in a name
other than that of the then Warrantholder as reflected upon the books of the
Company.

     1.6 Information. Upon receipt of a written request from a Warrantholder,
the Company agrees to deliver promptly to such Warrantholder a copy of its
current publicly available financial statements and to provide such other
publicly available information concerning the Company as such Warrantholder may
reasonably request (if electronic access to such information via EDGAR is not
then generally available to the public) in order to assist the Warrantholder in
evaluating the merits and risks of exercising the Warrant and to make an
informed investment decision in connection with such exercise.

     2. Registration Under the Securities Act of 1933.

     2.1 Piggyback Registration.

     (a) Right to Include Registrable Securities. If at any time or from time to
time prior to the fifth anniversary of the date hereof, the Company proposes to
register any of its securities under the Securities Act on any form for the
registration of securities under such Act, whether or not for its own account
(other than by a registration statement on Form S-8 or other form which does not
include substantially the same information as would be required in a form for
the general registration of securities or would not be available for the
Registrable Securities) (a "Piggyback Registration"), it shall as expeditiously
as reasonably possible give written notice to all Holders of its intention to do
so and of such Holders' rights under this Section 2.1. Such rights are referred
to hereinafter as "Piggyback Registration Rights." All references to "Warrant
Shares" and "Warrants" for purposes of this Article 2 shall refer to any such
shares or warrants issued by Diamond to S3. Upon the written request of any such
Holder made within ten (10) days after receipt of any such notice (which request
shall specify the Registrable Securities intended to be disposed of by such
Holder), the Company shall include in the Registration Statement the Registrable
Securities which the Company has been so requested to register by the Holders
thereof and the Company shall keep such registration statement in effect and
maintain compliance with each federal and state law or regulation for the period
necessary for such Holder to effect the proposed sale or other disposition (but
in no event for a period greater than ninety (90) days).

     (b) Withdrawal of Piggyback Registration by Company. If, at any time after
giving written notice of its intention to register any securities in a Piggyback
Registration but prior to the effective date of the related Registration
Statement, the Company shall determine for any reason not to register such
securities, the Company shall give notice of such determination to each Holder
and, thereupon, shall be relieved of its obligation to register any Registrable
Securi-

                                      -4-

<PAGE>

ties in connection with such Piggyback Registration. All best efforts
obligations of the Company pursuant to Section 2.4 shall cease if the Company
determines to terminate prior to such effective date any registration where
Registrable Securities are being registered pursuant to this Section 2.1.

     (c) Piggyback Registration of Underwritten Public Offerings. If a Piggyback
Registration involves an offering by or through underwriters, then (i) all
Holders requesting to have their Registrable securities included in the
Company's Registration Statement must sell their Registrable Securities to the
underwriters selected by the Company on the same terms and conditions as apply
to other selling shareholders and (ii) any Holder requesting to have his or its
Registrable Securities included in such Registration Statement may elect in
writing, not later than seven (7) Business Days prior to the effectiveness of
the Registration Statement filed in connection with such registration, not to
have his or its Registrable Securities so included in connection with such
registration.

     (d) Payment of Registration Expenses for Piggyback Registration. The
Company shall pay all Registration Expenses in connection with each registration
of Registrable Securities requested pursuant to a Piggyback Registration Right
contained in this Section 2.1.

     (e) Priority in Piggyback Registration. If a Piggyback Registration
involves an offering by or through underwriters, the Company, except as
otherwise provided herein, shall not be required to include Registrable
Securities therein if and to the extent the underwriter managing the offering
reasonably believes in good faith and advises each Holder requesting to have
Registrable Securities included in the Company's Registration Statement that
such inclusion would materially adversely affect such offering; provided that
(i) if other selling shareholders who are employees, officers, directors or
other affiliates of the Company have requested registration of securities in the
proposed offering, the Company will reduce or eliminate such other selling
shareholders' securities before any reduction or elimination of Registrable
Securities; and (ii) any such reduction or elimination (after taking into
account the effect of clause (i)) shall be pro rata to all other holders of the
securities of the Company exercising "Piggyback Registration Rights" similar to
those set forth herein in proportion to the respective number of shares they
have requested to be registered.

     2.2 Demand Registration.

     (a) Request for Registration. Unless this Warrant is exercised pursuant to
Section 1.1(b) hereof, if, at any time prior to the fifth anniversary of the
date hereof, Holders holding the greater of (i) at least twenty-five percent
(25%) of the combined total of Warrant Shares issuable and Warrant Shares
outstanding pursuant to the First Warrant and any subsequent warrant issued by
Diamond to S3 or (ii) one hundred percent (100%) of such shares issued or
issuable pursuant to the First Warrant, at such time request that the Company
file a registration statement on Form S-3 (or Form S-1 if Form S-3 is not then
available to the Company) under the Securities Act, as soon as practicable
thereafter the Company shall use its commercially reasonable efforts to file a
registration statement with respect to all Warrant Shares that it has been so
requested to include (the "Demand Registration") and obtain the effectiveness
thereof, and to take all other action necessary under any federal or state law
or regulation to permit the Warrant Shares that are held and/or that may be
acquired upon the exercise of the Warrants specified in the notices of the

                                      -5-

<PAGE>

Holders or holders thereof to be sold or otherwise disposed of, and the Company
shall maintain such compliance with each such federal and state law and
regulation for the period necessary for such Holders or holders to effect the
proposed sale or other disposition, which period shall be not less than thirty
(30) days; provided, however, the Company shall be entitled to defer such
registration for a period of up to forty-five (45) days if and to the extent
that its Board of Directors shall determine that such registration would
interfere with a pending corporate transaction. The Company shall also promptly
give written notice to the Holders and the holders of any other Warrants and/or
the holders of any Warrant Shares who or that have not made a request to the
Company pursuant to the provisions of this Section 2.2(a) of its intention to
effect any required registration or qualification, and shall use its
commercially reasonable efforts to effect as expeditiously as possible such
registration or qualification of all such other Warrant Shares that are then
held and/or that may be acquired upon the exercise of the Warrants, the Holder
or holders of which have requested such registration or qualification within
fifteen (15) days after such notice has been given by the Company. The Company
shall be required to effect a registration or qualification pursuant to this
Section 2.2(a) on a total of one (1) occasion.

     (b) Payment of Registration Expenses for Demand Registration. The Company
shall pay all Registration Expenses in connection with the Demand Registration.

     (c) Selection of Underwriters. If the Demand Registration is requested to
be in the form of an underwritten offering, the managing underwriter shall be
selected by the Holders of a majority of the Warrant Shares to be registered.
Such selection shall be subject to the Company's consent, which consent shall
not be unreasonably withheld.

     (d) Procedure for Requesting Demand Registration. Any request for a Demand
Registration shall specify the aggregate number of the Registrable Securities
proposed to be sold and the intended method of disposition. Within ten (10) days
after receipt of such a request the Company will give written notice of such
registration request to all Holders, and the Company will include in such
registration all Registrable Securities with respect to which the Company has
received written requests for inclusion therein within fifteen (15) Business
Days after the date on which such notice is given by the Company. Each such
request shall also specify the aggregate number of Registrable Securities to be
registered and the intended method of disposition thereof.

     2.3 Registration Procedures. If and whenever the Company is required to use
its commercially reasonable efforts to take action pursuant to any federal or
state law or regulation to permit the sale or other disposition of any
Registrable Securities that are then held or that may be acquired upon exercise
of the Warrants in order to effect or cause the registration of any Registrable
Securities under the Securities Act as provided in this Article 2, the Company
shall, as expeditiously as practicable:

     (a) prepare and file with the SEC, as soon as practicable within forty-five
(45) days after the end of the period within which requests for registration may
be given to the Company (but subject to the provision for deferral contained in
Section 2.2(a) hereof) a Registration Statement or Registration Statements
relating to the registration on any appropriate form under the Securities Act,
which form shall be available for the sale of the Registrable Securities in
accordance with the intended method or methods of distribution thereof, subject
to Section 2.1(e) hereof, and use its commercially reasonable efforts to cause
such Registration Statements to

                                      -6-

<PAGE>

become effective; provided that before filing a Registration Statement or
Prospectus or any amendment or supplements thereto, including documents
incorporated by reference after the initial filing of any Registration
Statement, the Company will furnish to the Holders of the Registrable Securities
covered by such Registration Statement and the underwriters, if any, copies of
all such documents provided to be filed, which documents will be subject to the
review of such Holders and underwriters;

     (b) prepare and file with the SEC such amendments and post-effective
amendments to a Registration Statement as may be necessary to keep such
Registration Statement effective for a period of thirty (30) days; cause the
related Prospectus to be supplemented by any required Prospectus supplement, and
as so supplemented to be filed pursuant to Rule 424 under the Securities Act;
and comply with the provisions of the Securities Act with respect to the
disposition of all securities covered by such Registration Statement during such
period in accordance with the intended methods of disposition by the sellers
thereof set forth in such Registration Statement or supplement to such
Prospectus;

     (c) notify the selling Holders of Registrable Securities and the managing
underwriters, if any, promptly, and (if requested by any such Person) confirm
such advice in writing, (i) when a Prospectus or any Prospectus supplement or
post-effective amendment has been filed, and, with respect to a Registration
Statement or any post-effective amendment, when the same has become effective;
(ii) of any request by the SEC for amendments or supplements to a Registration
Statement or related Prospectus or for additional information; (iii) of the
issuance by the SEC of any stop order suspending the effectiveness of a
Registration Statement or the initiation of any proceedings for that purpose;
(iv) if at any time the representations and warranties of the Company
contemplated by paragraph (m) below cease 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 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 happening of any event that makes any statement of
a material fact made in the Registration Statement, the Prospectus or any
document incorporated therein by reference untrue or which requires the making
of any changes in the Registration Statement or Prospectus so that they will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading;

     (d) make every reasonable effort to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement at the earliest
possible moment;

     (e) if reasonably requested by the managing underwriters, immediately
incorporate in a Prospectus supplement or post-effective amendment such
information as the managing underwriters believe (on advice of counsel) should
be included therein as required by applicable law relating to such sale of
Registrable Securities, including, without limitation, information with respect
to the purchase price being paid for the Registrable Securities by such
underwriters and with respect to any other terms of the underwritten (or
"best-efforts" underwritten) offering; and make all required filings of such
Prospectus supplement or post-effective amendment as soon as notified of the
matters to be incorporated in such Prospectus supplement or post-effective
amendment;

                                   -7-

<PAGE>

     (f) furnish to each selling Holder of Registrable Securities and each
managing underwriter, without charge, at least one signed copy of the
Registration Statement and any post-effective amendment thereto, including
financial statements and schedules, all documents incorporated therein by
reference and all exhibits (including those incorporated by reference);

     (g) deliver to each selling Holder of Registrable Securities and the
underwriters, if any, without charge, as many copies of the Prospectus or
Prospectuses (including each preliminary Prospectus) any amendment or supplement
thereto as such Persons may reasonably request; the Company consents to the use
of such Prospectus or any amendment or supplement thereto by each of the selling
Holders of Registrable Securities and the underwriters, if any, in connection
with the offering and sale of the Registrable Securities covered by such
Prospectus or any amendment or supplement thereto;

     (h) prior to any public offering of Registrable Securities, cooperate with
the selling Holders of Registrable Securities, the underwriters, if any, and
their respective counsel in connection with the 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 selling Holder or
underwriter reasonably requests in writing, keep each such registration or
qualification effective during the period such Registration Statement is
required to be kept effective and do any and all other acts or things necessary
or advisable to enable the disposition in such jurisdictions of the Registrable
Securities covered by the applicable Registration Statement; provided that the
Company will not be required to qualify to do business in any jurisdiction where
it is not then so qualified or to take any action which would subject the
Company to general service of process in any jurisdiction where it is not at the
time so subject;

     (i) cooperate with the selling Holders of Registrable Securities and the
managing underwriters, if any, to facilitate the timely preparation and delivery
of certificates representing Registrable Securities to be sold and not bearing
any restrictive legends; and enable such Registrable Securities to be in such
denominations and registered in such names as the managing underwriters may
request at least two (2) Business Days prior to any sale of Registrable
Securities to the underwriters;

     (j) use its commercially reasonable efforts to cause the Registrable
Securities covered by the applicable Registration Statement to be registered
with or approved by such other governmental agencies or authorities within the
United States as may be necessary to enable the seller or sellers thereof or the
underwriters, if any, to consummate the disposition of such Registrable
Securities;

     (k) upon the occurrence of any event contemplated by Section 2.3(c)(vi)
above, prepare a supplement or post-effective amendment to the applicable
Registration Statement or related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of the Registrable Securities being sold thereunder,
such that the Prospectus will not contain an untrue statement of a material fact
or omit to state any material fact necessary to make the statements therein not
misleading in the light of the circumstances under which they were made;

                                      -8-

<PAGE>

     (l) with respect to each issue or class of Registrable Securities, use its
commercially reasonable efforts to cause all Registrable Securities covered by
the Registration Statement to be listed on each securities exchange, if any, on
which similar securities issued by the Company are then listed if requested by
the Holders of a majority of such issue or class of Registrable Securities;

     (m) enter into such agreements (including an underwriting agreement) and
take all such other action reasonably required in connection therewith in order
to expedite or facilitate the disposition of such Registrable Securities and in
such connection, if the registration is in connection with an underwritten

such form, substance and scope as are customarily made by issuers to
underwriters in underwritten offerings and confirm the same if and when
requested; (ii) obtain opinions of counsel to the Company and updates thereof

satisfactory to the underwriters) addressed to the underwriters covering the
matters customarily covered in opinions requested in underwritten offerings and
such other matters as may be reasonably requested by such underwriters; (iii)
obtain "cold comfort" letters and updates thereof from the Company's accountants
addressed to the underwriters, such letters to be in customary form and covering

in any underwriting agreement entered into the indemnification provisions and
procedures of Section 2.4 hereof with respect to all parties to be indemnified
pursuant to said Section; and (v) deliver such documents and certificates as may
be reasonably requested by the underwriters to evidence compliance with clause
(i) above and with any customary conditions contained in the underwriting
agreement or other agreement entered into by the Company; the above shall be
done at each closing under such underwriting or similar agreement or as and to
the extent required hereunder;

     (n) make available for inspection by one or more representatives of the
Holders of Registrable Securities being sold, any underwriter participating in
any disposition pursuant to such registration, and any attorney or accountant
retained by such Holders or underwriter, all financial and other records,
pertinent corporate documents and properties of the Company, and cause the
Company's officers, directors and employees to supply all information reasonably
requested by any such representatives, in connection with such; and

     (o) otherwise use its commercially reasonable efforts to comply with all
applicable federal and state regulations; and take such other action as may be
reasonably necessary to or advisable to enable each such Holder and each such
underwriter to consummate the sale or disposition in such jurisdiction or
jurisdiction in which any such Holder or underwriter shall have requested that
the Registrable Securities be sold.

     Except as otherwise provided in this Agreement, the Company shall have sole
control in connection with the preparation, filing, withdrawal, amendment or
supplementing of each Registration Statement, the selection of underwriters, and
the distribution of any preliminary Prospectus included in the Registration
Statement, and may include within the coverage thereof additional shares of
Common Stock or other securities for its own account or for the account of one
or more of its other security holders.

                                      -9-

<PAGE>

         The Company may require  each seller of  Registrable  Securities  as to
which  any  registration  is being  effected  to  furnish  to the  Company  such
information  regarding  the  distribution  of such  securities  and  such  other
information as may otherwise be required by the Securities Act to be included in
such Registration Statement.

     2.4 Indemnification.

     (a) Indemnification by Company. In connection with each Registration
Statement relating to disposition of Registrable Securities, the Company shall
indemnify and hold harmless each Holder and each underwriter of Registrable
Securities and each Person, if any, who controls such Holder or underwriter
(within the meaning of section 15 of the Securities Act or section 20 of the
Exchange Act) against any and all losses, claims, damages and liabilities, joint
or several (including any reasonable investigation, legal and other expenses
incurred in connection with, and any amount paid in settlement of any action,
suit or proceeding or any claim asserted), to which they, or any of them, may
become subject under the Securities Act, the Exchange Act or other federal or
state law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement, Prospectus or preliminary Prospectus or any amendment
thereof or supplement thereto, or arise out of or are based upon any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading; provided, however,
that such indemnity shall not inure to the benefit of any Holder or underwriter
(or any person controlling such Holder or underwriter within the meaning of
section 15 of the Securities Act or section 20 of the Exchange Act) on account
of any losses, claims, damages or liabilities arising from the sale of the
Registrable Securities if such untrue statement or omission or alleged untrue
statement or omission was made in such Registration Statement, Prospectus or
preliminary Prospectus, or such amendment or supplement, in reliance upon and in
conformity with information furnished in writing to the Company by such Holder
or underwriter specifically for use therein; provided, further, that the Company
shall not be liable to such Holder or any underwriter (or any person controlling
such Holder or underwriter) with respect to any such untrue statement or alleged
untrue statement or omission made in any preliminary Prospectus that is
corrected in the Prospectus (or any amendment or supplement thereto) if the
person asserting any such loss, claim, damage or liability purchased shares of
the Common Stock from such Holder or underwriter but was not given a copy of the
Prospectus (as amended or supplemented) in any case where such delivery of the
Prospectus (as amended or supplemented) was required by the Securities Act. The
Company shall also indemnify selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, their
officers and directors and each Person who controls such Persons (within the
meaning of section 15 of the Securities Act or section 20 of the Exchange Act)
to the same extent as provided above with respect to the indemnification of the
Holders of Registrable Securities, if requested. This indemnity agreement shall
be in addition to any liability which the Company may otherwise have.

     (b) Indemnification by Holder. In connection with each Registration
Statement, each Holder shall indemnify, to the same extent as the
indemnification provided by the Company in Section 2.4(a), the Company, its
directors and each officer who signs the Registration Statement and each Person
who controls the Company (within the meaning of section 15 of the Securities

                                      -10-

<PAGE>

Act and section 20 of the Exchange Act) but only insofar as such losses, claims,
damages and liabilities arise out of or are based upon any untrue statement or
omission or alleged untrue statement or omission which was made in the
Registration Statement, the Prospectus or preliminary Prospectus or any
amendment thereof or supplement thereto, in reliance upon and in conformity with
information furnished in writing by such Holder to the Company specifically for
use therein. In no event shall the liability of any selling Holder of
Registrable Securities hereunder be greater in amount than the dollar amount of
the net proceeds received by such Holder upon the sale of the Registrable
Securities giving rise to such indemnification obligation. The Company shall be
entitled to receive indemnities from underwriters, selling brokers, dealer
managers and similar securities industry professionals participating in the
distribution, to the same extent as provided above, with respect to information
so furnished in writing by such Persons specifically for inclusion in any
Prospectus, Registration Statement or preliminary Prospectus or any amendment
thereof or supplement thereto.

     (c) Conduct of Indemnification Procedure. Any party that proposes to assert
the right to be indemnified hereunder will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim is to be made against an indemnifying party or parties under this
Section, notify each such indemnifying party of the commencement of such action,
suit or proceeding, enclosing a copy of all papers served. No indemnification
provided for in Section 2.4(a) or 2.4(b) shall be available to any party who
shall fail to give notice as provided in this Section 2.4(c) if the party to
whom notice was not given was unaware of the proceeding to which such notice
would have related and was materially prejudiced by the failure to give such
notice, but the omission so to notify such indemnifying party of any such
action, suit or proceeding shall not relieve it from any liability that it may
have to any indemnified party for contribution otherwise than under this
Section. In case any such action, suit or proceeding shall be brought against
any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
in, and, to the extent that it shall wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense thereof
and the approval by the indemnified party of such counsel, the indemnifying
party shall not be liable to such indemnified party for any legal or other
expenses, except as provided below and except for the reasonable costs of
investigation subsequently incurred by such indemnified party in connection with
the defense thereof. The indemnified party shall have the right to employ its
counsel in any such action, but the fees and expenses of such counsel shall be
at the expense of such indemnified party unless (i) the employment of counsel by
such indemnified party has been authorized in writing by the indemnifying
parties, (ii) the indemnified party shall have reasonably concluded that there
may be a conflict of interest between the indemnifying parties and the
indemnified party in the conduct of the defense of such action (in which case
the indemnifying parties shall not have the right to direct the defense of such
action on behalf of the indemnified party) or (iii) the indemnifying parties
shall not have employed counsel to assume the defense of such action within a
reasonable time after notice of the commencement thereof, in each of which cases
the fees and expenses of counsel shall be at the expense of the indemnifying
parties. An indemnified party shall not be liable for any settlement of any
action, suit, proceeding or claim effected without its written consent.

                                      -11-

<PAGE>

     (d) Contribution. In connection with each Registration Statement relating
to the disposition of Registrable Securities, if the indemnification provided
for in Section 2.4(a) or 2.4(b) hereof is unavailable to an indemnified party
thereunder in respect to any losses, claims, damages or liabilities referred to
therein, then the indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in paragraphs (a) or (b) of this Section 2.4 in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such losses, claims, damages
or liabilities, or actions in respect thereof, as well as any other relevant
equitable considerations. 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 the indemnified party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. 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 paragraph
(d) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim.

     (e) Underwriting Agreement to Control. Notwithstanding the foregoing
provisions of this Section 2.4, to the extent that the provisions on
indemnification and contribution contained in any underwriting agreement entered
into in connection with the underwritten public offering of the Registrable
Securities are in conflict with the foregoing provisions, the provisions in such
underwriting agreement shall control.

     (f) Specific Performance. The Company and the Holder acknowledge that
remedies at law for the enforcement of this Section 2.4 may be inadequate and

Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent
annual or quarterly report of the Company and such other reports and documents
so filed by the Company and (iii) such other information as may be reasonably

such form.

     2.6 Restrictions on Transfer; Compliance with Securities Laws. This Warrant
and the Warrant Shares issued upon the exercise of the Warrant may not be
transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and transferee
(including the delivery of investment representation letters and legal opinions
reasonably satisfactory to the Company, if such are requested by the Company).
The Warrantholder, by acceptance hereof, acknowledges that this Warrant and the
Warrant Shares to be issued upon exercise hereof are being acquired solely for
the Warrantholder's own account and not as a nominee for any other party, and
for investment, and that the Warrantholder will not offer, sell or otherwise
dispose of any Warrant Shares to be issued upon exercise hereof except under
circumstances that will not result in a violation of the Securities Act or any
state securities laws. Upon exercise of this Warrant, the Warrantholder shall,
if requested by the Company, confirm in writing, in a form satisfactory to the
Company, that the Warrant Shares so purchased are being acquired solely for the
Warrantholder's own account and not as a nominee for any other party, for
investment, and not with a view toward distribution or resale.

     2.7 Restrictive Legends. This Warrant shall (and each Warrant issued upon
transfer in whole or in part of this Warrant pursuant to this Section 2 or
issued in substitution for this Warrant pursuant to Section 4 shall) be stamped
or otherwise imprinted with a legend in substantially the following form:

     "THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT
     HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND
     MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT FILED UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION
     FROM REGISTRATION UNDER SUCH ACT."

Except as  otherwise  permitted by this  Section 2, each stock  certificate  for
Warrant  Shares  issued  upon  the  exercise  of  any  Warrant  and  each  stock
certificate  issued  upon the direct or indirect  transfer  of any such  Warrant
Shares shall be stamped or otherwise  imprinted  with a legend in  substantially
the following form:

         "THE SHARES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED
         UNDER THE  SECURITIES  ACT OF 1933, AS AMENDED,  AND MAY NOT BE SOLD OR
         OTHERWISE  TRANSFERRED  EXCEPT  PURSUANT TO AN  EFFECTIVE  REGISTRATION
         STATEMENT  FILED  UNDER  SUCH  ACT OR  PURSUANT  TO AN  EXEMPTION  FROM
         REGISTRATION UNDER SUCH ACT."

                                      -13-
<PAGE>

     Notwithstanding the foregoing, the Warrantholder may require the Company to
issue a stock certificate for Warrant Shares without a legend if (i) such
Warrant Shares, as the case may be, have been registered for resale under the
Securities Act or sold pursuant to Rule 144 under the Securities Act (or a
successor rule thereto) or (ii) the Warrantholder has received an opinion of
counsel reasonably satisfactory to the Company that such registration is not
required with respect to such Warrant Shares.

     3. Representations and Warranties of the Company. The Company hereby
represents and warrants to the Warrantholder (except as otherwise may be
prohibited, restricted or limited by law or any rule or regulation of a
regulatory entity) as follows:

     3.1 Organization; Authority Relative to this Warrant. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. The Company has all requisite corporate power and
authority to execute and deliver this Warrant, to perform its obligations
hereunder and to consummate the transactions contemplated hereby. The execution
and delivery of this Warrant by the Company and the consummation by the Company
of the transactions contemplated hereby have been duly and validly authorized by
all necessary corporate action on the part of the Company. This Warrant has been
duly and validly executed and delivered by the Company and constitutes a valid
and binding obligation of the Company enforceable against the Company in
accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting creditors' rights generally, and by general equitable principles.

     3.2 Authority to Issue Shares. The Company has taken all necessary
corporate action to authorize and reserve and permit it to issue, and at all
times from the date hereof through the end of the Exercise Period shall have
reserved, all the Warrant Shares issuable pursuant to this Warrant. All of the
shares of Common Stock issuable under this Warrant, upon their issuance and
delivery in accordance with the terms of this Warrant, will be duly authorized,
validly issued, fully paid and nonassessable, will be delivered free and clear
of all security interests, liens, claims, pledges, options, rights of first
refusal, agreements, limitations on the Warrantholder's voting rights, charges,
adverse rights and other encumbrances of any nature whatsoever (other than this
Warrant) and will not be subject to any preemptive rights.

     3.3 No Conflict; Required Filings and Consents.

     (a) The execution and delivery of this Warrant by the Company does not, and
the performance by the Company of its obligations hereunder and the consummation
of the transactions contemplated hereby will not, (i) conflict with or violate
the certificate of incorporation or bylaws of the Company, (ii) assuming that
all consents and filings described in Section 3.3(b) have been obtained or made,
conflict with or violate any law applicable to the Company or by which any
property or asset of the Company is bound or affected or (iii) result in any
violation pursuant to, any note, bond, mortgage, indenture, contract, agreement
, lease, license, permit, franchise or other instrument or obligation to which
the Company is a party or by which the Company or any of its properties may be
bound or affected.

     (b) No consent of, or filing with, any governmental entity is required by
the Company in connection with the execution and delivery of this Warrant, the
performance by the Company

                                      -14-

<PAGE>


of its obligations hereunder or the consummation by the Company of the
transactions contemplated hereby, except for (i) compliance with the
Hart-Scott-Rodino Act and (ii) consents or filings the failure of which to be
obtained or made would not, individually or in the aggregate, prevent or
materially delay the consummation of the transactions contemplated hereby or the
performance by the Company of any of its obligations hereunder.

     3.4 Reservation and Registration of Shares, Etc. The Company covenants and
agrees that all Warrant Shares which are issuable upon the exercise of this
Warrant will, upon issuance, be validly issued, fully paid and nonassessable and
free from all taxes, liens, security interests, charges and other encumbrances
with respect to the issue thereof, other than taxes in respect of any transfer
occurring contemporaneously with such issue. The Company further covenants and
agrees that, during the Exercise Period, the Company will at all times have
authorized and reserved, and keep available free from preemptive rights, a
sufficient number of shares of Common Stock to provide for the exercise of the
rights represented by this Warrant and will, at its expense, upon each such
reservation of shares, procure such listing of such shares of Common Stock
(subject to issuance or notice of issuance) as then may be required on all stock
exchanges on which the Common Stock is then listed or on Nasdaq.

     4. Exchange, Loss or Destruction of Warrant. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, of such bond or
indemnification as the Company may require, and, in the case of such mutilation,
upon surrender and cancellation of this Warrant, the Company will execute and
deliver a new Warrant of like tenor. The term "Warrant" as used in this
Agreement shall be deemed to include any Warrants issued in substitution or
exchange for this Warrant.

     5. Ownership of Warrant. The Company may deem and treat the person in whose
name this Warrant is registered as the holder and owner hereof (notwithstanding
any notations of ownership or writing hereon made by anyone other than the
Company) for all purposes and shall not be affected by any notice to the
contrary.

     6. Certain Adjustments.

     6.1 Adjustments. The number of Warrant Shares purchasable upon the exercise
of this Warrant and the Exercise Price shall be subject to adjustment as
follows:

     (a) Stock Dividends. If at any time prior to the exercise of this Warrant
in full (i) the Company shall fix a record date for the issuance of any stock
dividend payable in shares of Common Stock or (ii) the number of shares of
Common Stock shall have been increased by a subdivision or split-up of shares of
Common Stock, then, on the record date fixed for the determination of holders of
Common Stock entitled to receive such dividend or immediately after the
effective date of subdivision or split-up, as the case may be, the number of
shares of Common Stock to be delivered upon exercise of this Warrant will be
increased so that the Warrantholder will be entitled to receive the number of
shares of Common Stock that such Warrantholder would have owned immediately
following such action had this Warrant been exercised immediately prior thereto,
and the Exercise Price will be adjusted as provided below in paragraph (f).

                                      -15-

<PAGE>

     (b) Combination of Stock. If at any time prior to the exercise of this
Warrant in full the number of shares of Common Stock outstanding shall have been
decreased by a combination of the outstanding shares of Common Stock, then,
immediately after the effective date of such combination, the number of shares
of Common Stock to be delivered upon exercise of this Warrant will be decreased
so that the Warrantholder thereafter will be entitled to receive the number of
shares of Common Stock that such Warrantholder would have owned immediately
following such action had this Warrant been exercised immediately prior thereto,
and the Exercise Price will be adjusted as provided below in paragraph (f).

     (c) Reorganization, etc. If at any time prior to the exercise of this
Warrant in full any capital reorganization of the Company, or any
reclassification of the Common Stock, or any consolidation of the Company with
or merger of the Company with or into any other person or any sale, lease or
other transfer of all or substantially all of the assets of the Company to any
other person, shall be effected in such a way that the holders of Common Stock
shall be entitled to receive stock, other securities or assets (whether such
stock, other securities or assets are issued or distributed by the Company or
another person) with respect to or in exchange for Common Stock, then, upon
exercise of this Warrant the Warrantholder shall have the right to receive the
kind and amount of stock, other securities or assets receivable upon such
reorganization, reclassification, consolidation, merger or sale, lease or other
transfer by a holder of the number of shares of Common Stock that such
Warrantholder would have been entitled to receive upon exercise of this Warrant
had this Warrant been exercised immediately before such reorganization,
reclassification, consolidation, merger or sale, lease or other transfer,
subject to adjustments that shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Section 6.

     (d) Fractional Shares. No fractional shares of Common Stock or scrip shall
be issued to any Warrantholder in connection with the exercise of this Warrant.
Instead of any fractional shares of Common Stock that would otherwise be
issuable to such Warrantholder, the Company will pay to such Warrantholder a
cash adjustment in respect of such fractional interest in an amount equal to
that fractional interest of the fair market value of one share of Common Stock
as of the date of exercise.

     (e) Carryover. Notwithstanding any other provision of this Section 6, no
adjustment shall be made to the number of shares of Common Stock to be delivered
to the Warrantholder (or to the Exercise Price) if such adjustment represents
less than one percent (1%) of the number of shares to be so delivered, but any
lesser adjustment shall be carried forward and shall be made at the time and
together with the next subsequent adjustment which together with any adjustments
so carried forward shall amount to one percent (1%) or more of the number of
shares to be so delivered.

     (f) Exercise Price Adjustment. Whenever the number of Warrant Shares
purchasable upon the exercise of the Warrant is adjusted, as herein provided,
the Exercise Price payable upon the exercise of this Warrant shall be adjusted
by multiplying such Exercise Price immediately prior to such adjustment by a
fraction, of which the numerator shall be the number of Warrant Shares
purchasable upon the exercise of the Warrant immediately prior to such
adjustment, and of which the denominator shall be the number of Warrant Shares
purchasable immediately thereafter.

                                      -16-

<PAGE>

     (g) No Duplicate Adjustments. Notwithstanding anything else to the contrary
contained herein, in no event will an adjustment be made under the provisions of
this Section 6 to the number of Warrant Shares issuable upon exercise of this
Warrant or the Exercise Price for any event if an adjustment having
substantially the same effect to the Warrantholder as any adjustment that
otherwise would be made under the provisions of this Section 6 is made by the
Company for any such event to the number of shares of Common Stock (or other
securities) issuable upon exercise of this Warrant.

     6.2 No Adjustment for Dividends. Except as provided in Section 1 hereof or
Section 6.1 hereof, no adjustment in respect of any dividends shall be made
during the term of the Warrant or upon the exercise of this Warrant.

     6.3 Notice of Adjustment. Whenever the number of Warrant Shares or the
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail by first class, postage prepaid, to the
Warrantholder, notice of such adjustment or adjustments and a certificate of the
chief financial officer of the Company setting forth the number of Warrant
Shares and the Exercise Price of such Warrant Shares after such adjustment,
setting forth a brief statement of the facts requiring such adjustment and
setting forth the computation by which such adjustment was made.

     7. Notices of Corporate Action. In the event of:

     (a) any taking by the Company of a record of the holders of any class of
securities for the purpose of determining the holders thereof who are entitled
to receive any dividend or other distribution, or any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, or

     (b) any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any Change of Control,
or

     (c) any voluntary or involuntary dissolution, liquidation or winding-up of
the Company,

the Company will mail to the  Warrantholder a notice  specifying (i) the date or
expected  date on which any such  record is to be taken for the  purpose of such
dividend,  distribution  or  right  and the  amount  and  character  of any such
dividend, distribution or right, and (ii) the date or expected date on which any
such  reorganization,  reclassification,  recapitalization,  Change of  Control,
dissolution,  liquidation  or  winding-up  is to take place and the time, if any
such time is to be fixed,  as of which the holders of record of Common Stock (or
other securities) shall be entitled to exchange their shares of Common Stock (or
other  securities)  for the securities or other property  deliverable  upon such
reorganization,   reclassification,   recapitalization,   Change   of   Control,
dissolution, liquidation or winding-up. Such notice shall be mailed at least ten
(10) days prior to the date therein specified,  in the case of any date referred
to in the  foregoing  subdivision  (i),  and at least ten (10) days prior to the
date therein  specified,  in the case of the date  referred to in the  foregoing

     1. Exercise of Warrant.

     1.1 Duration and Exercise of Warrant.

     (a) Cash Exercise. This Warrant may be exercised by the Warrantholder by
(i) the surrender of this Warrant to the Company, with a duly executed Exercise
Form specifying the number of Warrant Shares to be purchased, during normal
business hours on any Business Day during the Exercise Period and (ii) the
delivery of payment to the Company, for the account of the Company, of the
Exercise Price for the number of Warrant Shares specified in the Exercise Form,
(A) by wire transfer of immediately available funds to a bank account specified
by the Company; (B) by certified or bank cashier's check; (C) by cancellation of
indebtedness under the Credit Agreement, or (D) of any other amount due to the
Warrantholder under any other contract (including any purchase order) pursuant
to which the Warrantholder does business with the Company not paid within twenty
(20) days of when due, or as otherwise mutually agreed to between the parties.
The Company agrees that such Warrant Shares shall be deemed to be issued to the
Warrantholder as the record holder of such Warrant Shares as of the close of
business on the date on which this Warrant shall have been surrendered and
payment made for the Warrant Shares as aforesaid. A stock certificate or
certificates for the Warrant Shares specified in the Exercise Form shall be
delivered to the Warrantholder as promptly as practicable. If this Warrant shall
have been exercised only in part, the Company shall, at the time of delivery of
the stock certificate or certificates, deliver to the Warrantholder a new
Warrant evidencing the rights to purchase the remaining Warrant Shares, which
new Warrant shall in all other respects be identical with this Warrant. No
adjustments shall be made on Warrant Shares issuable on the exercise of this
Warrant for any cash dividends paid or payable to holders of record of Common
Stock prior to the date as of which the Warrantholder shall be deemed to be the
record holder of such Warrant Shares.

     (b) Net Issue Exercise. In lieu of exercising this Warrant pursuant to
Section 1.1(a), this Warrant may be exercised by the Warrantholder by the
surrender of this Warrant to the Company, with a duly executed Exercise Form
marked to reflect Net Issue Exercise and specifying the number of Warrant Shares
to be purchased, during normal business hours on any Business Day during the
Exercise Period. The Company agrees that such Warrant Shares shall be deemed to
be issued to the Warrantholder as the record holder of such Warrant Shares as of
the close of business on the date on which this Warrant shall have been
surrendered as aforesaid. Upon such exercise, the Warrantholder shall be
entitled to receive shares equal to the value of this Warrant (or the portion
hereof being exercised) computed as of the date of surrender of this Warrant to
the Company using the following formula:

     X = Y x (A-B)
         ---------
             A


Where    X =  the number of shares of Common Stock to be issued to Warrantholder
              under this Section 1.1(b);

         Y =  the number of shares of Common Stock otherwise purchasable under
              this Warrant (at the date of such calculation);

                                      -2-

<PAGE>

         A =      the fair market value of one share of Common Stock (at the
                  date of such calculation);

         B =      the Exercise Price (as adjusted to the date of such
                  calculation).

     (c) Fair Market Value. For purposes of Section 1.1(b) "fair market value"
of one share of Common Stock shall mean:

          (i) the average closing price per share of the Common Stock on the---
     principal national securities exchange on which the Common Stock is listed
     or admitted to trading for the ten (10) Trading Day period ending on the
     date of exercise, or,

          (ii) if not listed or traded on any such exchange, the average last
     reported sales price per share of the Common Stock on the Nasdaq National
     Market or The Nasdaq SmallCap Market (collectively, "Nasdaq") for the ten
     (10) Trading Day period ending on the date of exercise, or,

          (iii) if not listed or traded on any such exchange or Nasdaq, the
     average of the mean of the bid and asked prices per share of the Common
     Stock as reported in the OTC Bulletin Board or, if not so reported, in the
     "pink sheets" published by the National Quotation Bureau, Inc. for the ten
     (10) Trading Day period ending on the date of exercise, or,

          (iv) if such quotations are not available, the fair market value per
     share of the Common Stock on the date such notice was received by the
     Company as reasonably determined by the Board of Directors of the Company.

     1.2 Number of Warrant Shares. This Warrant shall entitle the Warrantholder
to purchase 1,196,172 shares of Common Stock.

     1.3 Exercise Price. The Exercise Price shall be equal to $4.18 (the
"Exercise Price"). From and after the issuance of this Warrant, the Exercise
Price shall be adjusted in accordance with Section 6 hereof.

     1.4 Term of Warrant and Exercisability.

     (a) Term of Warrant. This Warrant shall terminate on the later of (i) June
15, 2000; (ii) the date on which the indebtedness of the Company to the
Warrantholder under the Credit Agreement is paid in full; provided, however,
that this Warrant shall terminate upon the consummation of an S3 Acquisition.
Nothing in this Section 1.4(a), however, shall require S3 or Diamond to
negotiate or enter into an agreement providing for the merger of Diamond with S3
(directly or indirectly), and neither party shall have any liability for failing
to do so. The parties' rights and obligations under Sections 2, 8 and 9 hereof
shall survive the termination of this Warrant.

     (b) Exercisability. This Warrant shall be immediately exercisable, during
the Exercise Period, in whole or in part as to ninety-nine percent (99%) of the
Warrant Shares. This

                                      -3-

<PAGE>

Warrant shall become exercisable, during the Exercise Period, as to the
remaining one percent (1%) of the Warrant Shares upon a Change of Control of
Diamond. Notwithstanding anything to the contrary herein, this Warrant may not
be exercised prior to June 15, 1999.

     1.5 Payment of Taxes. The issuance of certificates for Warrant Shares shall
be made without charge to the Warrantholder for any stock transfer or other
issuance tax in respect thereto; provided, however, that the Warrantholder shall
be required to pay any and all taxes which may be payable in respect of any
transfer involved in the issuance and delivery of any certificate in a name
other than that of the then Warrantholder as reflected upon the books of the
Company.

     1.6 Information. Upon receipt of a written request from a Warrantholder,
the Company agrees to deliver promptly to such Warrantholder a copy of its
current publicly available financial statements and to provide such other
publicly available information concerning the Company as such Warrantholder may
reasonably request (if electronic access to such information via EDGAR is not
then generally available to the public) in order to assist the Warrantholder in
evaluating the merits and risks of exercising the Warrant and to make an
informed investment decision in connection with such exercise.

     2. Registration Under the Securities Act of 1933.

     2.1 Piggyback Registration.

     (a) Right to Include Registrable Securities. If at any time or from time to
time prior to the fifth anniversary of the date hereof, the Company proposes to
register any of its securities under the Securities Act on any form for the
registration of securities under such Act, whether or not for its own account
(other than by a registration statement on Form S-8 or other form which does not
include substantially the same information as would be required in a form for
the general registration of securities or would not be available for the
Registrable Securities) (a "Piggyback Registration"), it shall as expeditiously
as reasonably possible give written notice to all Holders of its intention to do
so and of such Holders' rights under this Section 2.1. Such rights are referred
to hereinafter as "Piggyback Registration Rights." All references to "Warrant
Shares" and "Warrants" for purposes of this Article 2 shall refer to any such
shares or warrants issued by Diamond to S3. Upon the written request of any such
Holder made within ten (10) days after receipt of any such notice (which request
shall specify the Registrable Securities intended to be disposed of by such
Holder), the Company shall include in the Registration Statement the Registrable
Securities which the Company has been so requested to register by the Holders
thereof and the Company shall keep such registration statement in effect and
maintain compliance with each federal and state law or regulation for the period
necessary for such Holder to effect the proposed sale or other disposition (but
in no event for a period greater than ninety (90) days).

     (b) Withdrawal of Piggyback Registration by Company. If, at any time after
giving written notice of its intention to register any securities in a Piggyback
Registration but prior to the effective date of the related Registration
Statement, the Company shall determine for any reason not to register such
securities, the Company shall give notice of such determination to each Holder
and, thereupon, shall be relieved of its obligation to register any Registrable
Securi-

                                      -4-
<PAGE>

ties in connection with such Piggyback Registration. All best efforts
obligations of the Company pursuant to Section 2.4 shall cease if the Company
determines to terminate prior to such effective date any registration where
Registrable Securities are being registered pursuant to this Section 2.1.

     (c) Piggyback Registration of Underwritten Public Offerings. If a Piggyback
Regis-tration involves an offering by or through underwriters, then (i) all
Holders requesting to have their Registrable securities included in the
Company's Registration Statement must sell their Registrable Securities to the
underwriters selected by the Company on the same terms and conditions as apply
to other selling shareholders and (ii) any Holder requesting to have his or its
Registrable Securities included in such Registration Statement may elect in
writing, not later than seven (7) Business Days prior to the effectiveness of
the Registration Statement filed in connection with such registration, not to
have his or its Registrable Securities so included in connection with such
registration.

     (d) Payment of Registration Expenses for Piggyback Registration. The
Company shall pay all Registration Expenses in connection with each registration
of Registrable Securities requested pursuant to a Piggyback Registration Right
contained in this Section 2.1.

     (e) Priority in Piggyback Registration. If a Piggyback Registration
involves an offering by or through underwriters, the Company, except as
otherwise provided herein, shall not be required to include Registrable
Securities therein if and to the extent the underwriter managing the offering
reasonably believes in good faith and advises each Holder requesting to have
Registrable Securities included in the Company's Registration Statement that
such inclusion would materially adversely affect such offering; provided that
(i) if other selling shareholders who are employees, officers, directors or
other affiliates of the Company have requested registration of securities in the
proposed offering, the Company will reduce or eliminate such other selling
shareholders' securities before any reduction or elimination of Registrable
Securities; and (ii) any such reduction or elimination (after taking into
account the effect of clause (i)) shall be pro rata to all other holders of the
securities of the Company exercising "Piggyback Registration Rights" similar to
those set forth herein in proportion to the respective number of shares they
have requested to be registered.

     2.2 Demand Registration.

     (a) Request for Registration. Unless this Warrant is exercised pursuant to
Section 1.1(b) hereof, if, at any time prior to the fifth anniversary of the
date hereof, Holders holding the greater of (i) at least twenty-five percent
(25%) of the combined total of Warrant Shares issuable and Warrant Shares
outstanding pursuant to the Second Warrant and any prior or subsequent warrant
issued by Diamond to S3 or (ii) one hundred percent (100%) of such shares issued
or issuable pursuant to the First Warrant, at such time request that the Company
file a registration statement on Form S-3 (or Form S-1 if Form S-3 is not then
available to the Company) under the Securities Act, as soon as practicable
thereafter the Company shall use its commercially reasonable efforts to file a
registration statement with respect to all Warrant Shares that it has been so
requested to include (so long as such Warrant Shares represent the greater of
the amount set forth in clause (i) or clause (ii) above)(the "Demand
Registration") and obtain the effectiveness thereof, and to take all other
action necessary under any federal or state law or

                                      -5-

<PAGE>

regulation to permit the Warrant Shares that are held and/or that may be
acquired upon the exercise of the Warrants specified in the notices of the
Holders or holders thereof to be sold or otherwise disposed of, and the Company
shall maintain such compliance with each such federal and state law and
regulation for the period necessary for such Holders or holders to effect the
proposed sale or other disposition, which period shall be not less than thirty
(30) days; provided, however, the Company shall be entitled to defer such
registration for a period of up to forty-five (45) days if and to the extent
that its Board of Directors shall determine that such registration would
interfere with a pending corporate transaction. The Company shall also promptly
give written notice to the Holders and the holders of any other Warrants and/or
the holders of any Warrant Shares who or that have not made a request to the
Company pursuant to the provisions of this Section 2.2(a) of its intention to
effect any required registration or qualification, and shall use its
commercially reasonable efforts to effect as expeditiously as possible such
registration or qualification of all such other Warrant Shares that are then
held and/or that may be acquired upon the exercise of the Warrants, the Holder
or holders of which have requested such registration or qualification within
fifteen (15) days after such notice has been given by the Company. The Company
shall be required to effect a registration or qualification pursuant to this
Section 2.2(a) on a total of one (1) occasion.

     (b) Payment of Registration Expenses for Demand Registration. The Company
shall pay all Registration Expenses in connection with the Demand Registration.

     (c) Selection of Underwriters. If the Demand Registration is requested to
be in the form of an underwritten offering, the managing underwriter shall be
selected by the Holders of a majority of the Warrant Shares to be registered.
Such selection shall be subject to the Company's consent, which consent shall
not be unreasonably withheld.

     (d) Procedure for Requesting Demand Registration. Any request for a Demand
Registration shall specify the aggregate number of the Registrable Securities
proposed to be sold and the intended method of disposition. Within ten (10) days
after receipt of such a request the Company will give written notice of such
registration request to all Holders, and the Company will include in such
registration all Registrable Securities with respect to which the Company has
received written requests for inclusion therein within fifteen (15) Business
Days after the date on which such notice is given by the Company. Each such
request shall also specify the aggregate number of Registrable Securities to be
registered and the intended method of disposition thereof.

     2.3 Registration Procedures. If and whenever the Company is required to use
its commercially reasonable efforts to take action pursuant to any federal or
state law or regulation to permit the sale or other disposition of any
Registrable Securities that are then held or that may be acquired upon exercise
of the Warrants in order to effect or cause the registration of any Registrable
Securities under the Securities Act as provided in this Article 2, the Company
shall, as expeditiously as practicable:

     (a) prepare and file with the SEC, as soon as practicable within forty-five
(45) days after the end of the period within which requests for registration may
be given to the Company (but subject to the provision for deferral contained in
Section 2.2(a) hereof) a Registration Statement or Registration Statements
relating to the registration on any appropriate form under the Securities Act,
which form shall be available for the sale of the Registrable Securities in

                                      -6-

<PAGE>

accordance with the intended method or methods of distribution thereof, subject
to Section 2.1(e) hereof, and use its commercially reasonable efforts to cause
such Registration Statements to become effective; provided that before filing a
Registration Statement or Prospectus or any amend-ment or supplements thereto,
including documents incorporated by reference after the initial filing of any
Registration Statement, the Company will furnish to the Holders of the
Regis-trable Securities covered by such Registration Statement and the
underwriters, if any, copies of all such documents provided to be filed, which
documents will be subject to the review of such Holders and underwriters;

     (b) prepare and file with the SEC such amendments and post-effective
amendments to a Registration Statement as may be necessary to keep such
Registration Statement effective for a period of thirty (30) days; cause the
related Prospectus to be supplemented by any required Prospectus supplement, and
as so supplemented to be filed pursuant to Rule 424 under the Securities Act;
and comply with the provisions of the Securities Act with respect to the
disposition of all securities covered by such Registration Statement during
such period in accordance with the intended methods of disposition by the
sellers thereof set forth in such Registration Statement or supplement to such
Prospectus;

     (c) notify the selling Holders of Registrable Securities and the managing
underwriters, if any, promptly, and (if requested by any such Person) confirm
such advice in writing, (i) when a Prospectus or any Prospectus supplement or
post-effective amendment has been filed, and, with respect to a Registration
Statement or any post-effective amendment, when the same has become effective;
(ii) of any request by the SEC for amendments or supplements to a Registration
Statement or related Prospectus or for additional information; (iii) of the
issuance by the SEC of any stop order suspending the effectiveness of a
Registration Statement or the initiation of any proceedings for that purpose;
(iv) if at any time the representations and warranties of the Company
contemplated by paragraph (m) below cease 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 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 happening of any event that makes any statement of
a material fact made in the Registration Statement, the Prospectus or any
document incorporated therein by reference untrue or which requires the making
of any changes in the Registration Statement or Prospectus so that they will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading;

     (d) make every reasonable effort to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement at the earliest
possible moment;

     (e) if reasonably requested by the managing underwriters, immediately
incorporate in a Prospectus supplement or post-effective amendment such
information as the managing underwriters believe (on advice of counsel) should
be included therein as required by applicable law relating to such sale of
Registrable Securities, including, without limitation, information with respect
to the purchase price being paid for the Registrable Securities by such
underwriters and with respect to any other terms of the underwritten (or
"best-efforts" underwritten) offering; and make all required filings of such
Prospectus supplement or post-effective amendment as soon as

                                      -7-

<PAGE>

notified of the matters to be incorporated in such Prospectus supplement or
post-effective amendment;

     (f) furnish to each selling Holder of Registrable Securities and each
managing underwriter, without charge, at least one signed copy of the
Registration Statement and any post-effective amendment thereto, including
financial statements and schedules, all documents incorporated therein by
reference and all exhibits (including those incorporated by reference);

     (g) deliver to each selling Holder of Registrable Securities and the
underwriters, if any, without charge, as many copies of the Prospectus or
Prospectuses (including each preliminary Prospectus) any amendment or supplement
thereto as such Persons may reasonably request; the Company consents to the use
of such Prospectus or any amendment or supplement thereto by each of the selling
Holders of Registrable Securities and the underwriters, if any, in connection
with the offering and sale of the Registrable Securities covered by such
Prospectus or any amendment or supplement thereto;

     (h) prior to any public offering of Registrable Securities, cooperate with
the selling Holders of Registrable Securities, the underwriters, if any, and
their respective counsel in connection with the 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 selling Holder or
underwriter reasonably requests in writing, keep each such registration or
qualification effective during the period such Registration Statement is
required to be kept effective and do any and all other acts or things necessary
or advisable to enable the disposition in such jurisdictions of the Registrable
Securities covered by the applicable Registration Statement; provided that the
Company will not be required to qualify to do business in any jurisdiction where
it is not then so qualified or to take any action which would subject the
Company to general service of process in any jurisdiction where it is not at the
time so subject;

     (i) cooperate with the selling Holders of Registrable Securities and the
managing underwriters, if any, to facilitate the timely preparation and delivery
of certificates representing Registrable Securities to be sold and not bearing
any restrictive legends; and enable such Registrable Securities to be in such
denominations and registered in such names as the managing underwriters may
request at least two (2) Business Days prior to any sale of Registrable
Securities to the underwriters;

     (j) use its commercially reasonable efforts to cause the Registrable
Securities covered by the applicable Registration Statement to be registered
with or approved by such other governmental agencies or authorities within the
United States as may be necessary to enable the seller or sellers thereof or the
underwriters, if any, to consummate the disposition of such Registrable
Securities;

     (k) upon the occurrence of any event contemplated by Section 2.3(c)(vi)
above, prepare a supplement or post-effective amendment to the applicable
Registration Statement or related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of the Registrable Securities being sold thereunder,
such that the Prospectus will not contain an untrue statement of a material fact

                                      -8-

<PAGE>

or omit to state any material fact necessary to make the statements therein not
misleading in the light of the circumstances under which they were made;

     (l) with respect to each issue or class of Registrable Securities, use its
commercially reasonable efforts to cause all Registrable Securities covered by
the Registration Statement to be listed on each securities exchange, if any, on
which similar securities issued by the Company are then listed if requested by
the Holders of a majority of such issue or class of Registrable Securities;

     (m) enter into such agreements (including an underwriting agreement) and
take all such other action reasonably required in connection therewith in order
to expedite or facilitate the disposition of such Registrable Securities and in
such connection, if the registration is in connection with an underwritten

such form, substance and scope as are customarily made by issuers to
underwriters in underwritten offerings and confirm the same if and when
requested; (ii) obtain opinions of counsel to the Company and updates thereof

obtain "cold comfort" letters and updates thereof from the Company's accountants
addressed to the underwriters, such letters to be in customary form and covering
matters of the type customarily covered in "cold comfort" letters by
underwriters in connection with underwritten offerings; (iv) set forth in full
in any underwriting agreement entered into the indemnification provisions and
procedures of Section 2.4 hereof with respect to all parties to be indemnified
pursuant to said Section; and (v) deliver such documents and certificates as may
be reasonably requested by the underwriters to evidence compliance with clause
(i) above and with any customary conditions contained in the underwriting
agreement or other agreement entered into by the Company; the above shall be
done at each closing under such underwriting or similar agreement or as and to
the extent required hereunder;

     (n) make available for inspection by one or more representatives of the
Holders of Registrable Securities being sold, any underwriter participating in
any disposition pursuant to such registration, and any attorney or accountant
retained by such Holders or underwriter, all financial and other records,
pertinent corporate documents and properties of the Company, and cause the
Company's officers, directors and employees to supply all information reasonably
requested by any such representatives, in connection with such; and

     (o) otherwise use its commercially reasonable efforts to comply with all
applicable federal and state regulations; and take such other action as may be
reasonably necessary to or advisable to enable each such Holder and each such
underwriter to consummate the sale or disposition in such jurisdiction or
jurisdiction in which any such Holder or underwriter shall have requested that
the Registrable Securities be sold.

     Except as otherwise provided in this Agreement, the Company shall have sole
control in connection with the preparation, filing, withdrawal, amendment or
supplementing of each Registration Statement, the selection of underwriters, and
the distribution of any preliminary Prospectus included in the Registration
Statement, and may include within the coverage thereof

                                      -9-

<PAGE>

additional shares of Common Stock or other securities for its own account or for
the account of one or more of its other security holders.

     The Company may require each seller of Registrable Securities
as to which any registration is being effected to furnish to the Company such
information regarding the distribution of such securities and such other
information as may otherwise be required by the Securities Act to be included in
such Registration Statement. 2.4 Indemnification.

     (a) Indemnification by Company. In connection with each Registration
Statement relating to disposition of Registrable Securities, the Company shall
indemnify and hold harmless each Holder and each underwriter of Registrable
Securities and each Person, if any, who controls such Holder or underwriter
(within the meaning of section 15 of the Securities Act or section 20 of the
Exchange Act) against any and all losses, claims, damages and liabilities, joint
or several (including any reasonable investigation, legal and other expenses
incurred in connection with, and any amount paid in settlement of any action,
suit or proceeding or any claim asserted), to which they, or any of them, may
become subject under the Securities Act, the Exchange Act or other federal or
state law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement, Prospectus or preliminary Prospectus or any amendment
thereof or supplement thereto, or arise out of or are based upon any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading; provided, however,
that such indemnity shall not inure to the benefit of any Holder or underwriter
(or any person controlling such Holder or underwriter within the meaning of
section 15 of the Securities Act or section 20 of the Exchange Act) on account
of any losses, claims, damages or liabilities arising from the sale of the
Registrable Securities if such untrue statement or omission or alleged untrue
statement or omission was made in such Registration Statement, Prospectus or
preliminary Prospectus, or such amendment or supplement, in reliance upon and in
conformity with information furnished in writing to the Company by such Holder
or underwriter specifically for use therein; provided, further, that the Company
shall not be liable to such Holder or any underwriter (or any person controlling
such Holder or underwriter) with respect to any such untrue statement or alleged
untrue statement or omission made in any preliminary Prospectus that is
corrected in the Prospectus (or any amendment or supplement thereto) if the
person asserting any such loss, claim, damage or liability purchased shares of
the Common Stock from such Holder or underwriter but was not given a copy of the
Prospectus (as amended or supplemented) in any case where such delivery of the
Prospectus (as amended or supplemented) was required by the Securities Act. The
Company shall also indemnify selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, their
officers and directors and each Person who controls such Persons (within the
meaning of section 15 of the Securities Act or section 20 of the Exchange Act)
to the same extent as provided above with respect to the indemnification of the
Holders of Registrable Securities, if requested. This indemnity agreement shall
be in addition to any liability which the Company may otherwise have.


     (b) Indemnification by Holder. In connection with each Registration
Statement, each Holder shall indemnify, to the same extent as the
indemnification provided by the Company in

                                      -10-

<PAGE>


Section 2.4(a), the Company, its directors and each officer who signs the
Registration Statement and each Person who controls the Company (within the
meaning of section 15 of the Securities Act and section 20 of the Exchange Act)
but only insofar as such losses, claims, damages and liabilities arise out of or
are based upon any untrue statement or omission or alleged untrue statement or
omission which was made in the Registration Statement, the Prospectus or
preliminary Prospectus or any amendment thereof or supplement thereto, in
reliance upon and in con-formity with information furnished in writing by such
Holder to the Company specifically for use therein. In no event shall the
liability of any selling Holder of Registrable Securities hereunder be greater
in amount than the dollar amount of the net proceeds received by such Holder
upon the sale of the Registrable Securities giving rise to such indemnification
obligation. The Company shall be entitled to receive indemnities from
underwriters, selling brokers, dealer managers and similar securities industry
professionals participating in the distribution, to the same extent as provided
above, with respect to information so furnished in writing by such Persons
specifically for inclusion in any Prospectus, Registration Statement or
preliminary Prospectus or any amendment thereof or supplement thereto.


     (c) Conduct of Indemnification Procedure. Any party that proposes to assert
the right to be indemnified hereunder will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim is to be made against an indemnifying party or parties under this
Section, notify each such indemnifying party of the commencement of such action,
suit or proceeding, enclosing a copy of all papers served. No indemnification
provided for in Section 2.4(a) or 2.4(b) shall be available to any party who
shall fail to give notice as provided in this Section 2.4(c) if the party to
whom notice was not given was unaware of the proceeding to which such notice
would have related and was materially prejudiced by the failure to give such
notice, but the omission so to notify such indemnifying party of any such
action, suit or proceeding shall not relieve it from any liability that it may
have to any indemnified party for contribution otherwise than under this
Section. In case any such action, suit or proceeding shall be brought against
any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
in, and, to the extent that it shall wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense thereof
and the approval by the indemnified party of such counsel, the indemnifying
party shall not be liable to such indemnified party for any legal or other
expenses, except as provided below and except for the reasonable costs of
investigation subsequently incurred by such indemnified party in connection with
the defense thereof. The indemnified party shall have the right to employ its
counsel in any such action, but the fees and expenses of such counsel shall be
at the expense of such indemnified party unless (i) the employment of counsel by
such indemnified party has been authorized in writing by the indemnifying
parties, (ii) the indemnified party shall have reasonably concluded that there
may be a conflict of interest between the indemnifying parties and the
indemnified party in the conduct of the defense of such action (in which case
the indemnifying parties shall not have the right to direct the defense of such
action on behalf of the indemnified party) or (iii) the indemnifying parties
shall not have employed counsel to assume the defense of such action within a
reasonable time after notice of the commencement thereof, in each of which cases
the fees and expenses of counsel shall be at

                                      -11-
<PAGE>


the expense of the indemnifying parties. An indemnified party shall not be
liable for any settlement of any action, suit, proceeding or claim effected
without its written consent.

     (d) Contribution. In connection with each Registration Statement relating
to the disposition of Registrable Securities, if the indemnification provided
for in Section 2.4(a) or 2.4(b) hereof is unavailable to an indemnified party
thereunder in respect to any losses, claims, damages or liabilities referred to
therein, then the indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in paragraphs (a) or (b) of this Section 2.4 in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such losses, claims, damages
or liabilities, or actions in respect thereof, as well as any other relevant
equitable con-siderations. 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 the indemnified party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. 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 paragraph
(d) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim.

     (e) Underwriting Agreement to Control. Notwithstanding the foregoing
provisions of this Section 2.4, to the extent that the provisions on
indemnification and contribution contained in any underwriting agreement entered
into in connection with the underwritten public offering of the Registrable
Securities are in conflict with the foregoing provisions, the provisions in such
underwriting agreement shall control.

     (f) Specific Performance. The Company and the Holder acknowledge that
remedies at law for the enforcement of this Section 2.4 may be inadequate and
intend that this Section 2.4 shall be specifically enforceable.

     (g) Survival of Obligations. The obligations of the Company and the Holder
under this Section 2.4 shall survive the completion of any offering of
Registrable Securities pursuant to a Registration Statement under this Article
2, and otherwise.


     2.5 Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:

     (a) make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times;

     (b) file with the SEC in a timely manner all reports and other documents
required of the Company under the Securi-ties Act and the Exchange Act; and

                                      -12-

<PAGE>


(c) furnish to any Holder, so long as
the Holder owns any Registrable Securities, forthwith upon request (i) a written
statement by the Company that it has complied with the reporting requirements of
SEC Rule 144, the Securities Act and the Exchange Act, or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

     2.6 Restrictions on Transfer; Compliance with Securities Laws. This Warrant
and the Warrant Shares issued upon the exercise of the Warrant may not be
transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and transferee
(including the delivery of investment representation letters and legal opinions
reasonably satisfactory to the Company, if such are requested by the Company).
The Warrantholder, by acceptance hereof, acknowledges that this Warrant and the
Warrant Shares to be issued upon exercise hereof are being acquired solely for
the Warrantholder's own account and not as a nominee for any other party, and
for investment, and that the Warrantholder will not offer, sell or otherwise
dispose of any Warrant Shares to be issued upon exercise hereof except under
circumstances that will not result in a violation of the Securities Act or any
state securities laws. Upon exercise of this Warrant, the Warrantholder shall,
if requested by the Company, confirm in writing, in a form satisfactory to the
Company, that the Warrant Shares so purchased are being acquired solely for the
Warrantholder's own account and not as a nominee for any other party, for
investment, and not with a view toward distribution or resale.

     2.7 Restrictive Legends. This Warrant shall (and each Warrant issued upon
transfer in whole or in part of this Warrant pursuant to this Section 2 or
issued in substitution for this Warrant pursuant to Section 4 shall) be stamped
or otherwise imprinted with a legend in substantially the following form:

     "THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT
     HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND
     MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT FILED UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION
     FROM REGISTRATION UNDER SUCH ACT."

Except as otherwise permitted by this Section 2, each stock certificate for
Warrant Shares issued upon the exercise of any Warrant and each stock
certificate issued upon the direct or indirect transfer of any such Warrant
Shares shall be stamped or otherwise imprinted with a legend in substantially
the following form:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD OR OTHERWISE
     TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FILED
     UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH
     ACT."


                                  -13-
<PAGE>

     Notwithstanding the foregoing, the Warrantholder may require the Company to
issue a stock certificate for Warrant Shares without a legend if (i) such
Warrant Shares, as the case may be, have been registered for resale under the
Securities Act or sold pursuant to Rule 144 under the Securities Act (or a
successor rule thereto) or (ii) the Warrantholder has received an opinion of
counsel reasonably satisfactory to the Company that such registration is not
required with respect to such Warrant Shares.

     3. Representations and Warranties of the Company. The Company hereby
represents and warrants to the Warrantholder (except as otherwise may be
prohibited, restricted or limited by law or any rule or regulation of a
regulatory entity) as follows:


     3.1 Organization; Authority Relative to this Warrant. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. The Company has all requisite corporate power and
authority to execute and deliver this Warrant, to perform its obligations
hereunder and to consummate the transactions contemplated hereby. The execution
and delivery of this Warrant by the Company and the consummation by the Company
of the transactions contemplated hereby have been duly and validly authorized by
all necessary corporate action on the part of the Company. This Warrant has been
duly and validly executed and delivered by the Company and constitutes a valid
and binding obligation of the Company enforceable against the Company in
accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting creditors' rights generally, and by general equitable principles.


     3.2 Authority to Issue Shares. The Company has taken all necessary
corporate action to authorize and reserve and permit it to issue, and at all
times from the date hereof through the end of the Exercise Period shall have
reserved, all the Warrant Shares issuable pursuant to this Warrant. All of the
shares of Common Stock issuable under this Warrant, upon their issuance and
delivery in accordance with the terms of this Warrant, will be duly authorized,
validly issued, fully paid and nonassessable, will be delivered free and clear
of all security interests, liens, claims, pledges, options, rights of first
refusal, agreements, limitations on the Warrantholder's voting rights, charges,
adverse rights and other encumbrances of any nature whatsoever (other than this
Warrant) and will not be subject to any preemptive rights.


     3.3 No Conflict; Required Filings and Consents.

     (a) The execution and delivery of this Warrant by the Company does not, and
the performance by the Company of its obligations hereunder and the consummation
of the trans-actions contemplated hereby will not, (i) conflict with or violate
the certificate of incorporation or bylaws of the Company, (ii) assuming that
all consents and filings described in Section 3.3(b) have been obtained or made,
conflict with or violate any law applicable to the Company or by which any
property or asset of the Company is bound or affected or (iii) result in any
violation pursuant to, any note, bond, mortgage, indenture, contract, agreement,
lease, license, permit, franchise or other instrument or obligation to which the
Company is a party or by which the Company or any of its properties may be bound
or affected.

     (b) No consent of, or filing with, any governmental entity is required by
the Company in connection with the execution and delivery of this Warrant, the
performance by the Company

                                      -14-

<PAGE>


of its obligations hereunder or the consummation by the Company of the
transactions contemplated hereby, except for (i) compliance with the
Hart-Scott-Rodino Act and (ii) consents or filings the failure of which to be
obtained or made would not, individually or in the aggregate, prevent or
materially delay the consummation of the transactions contemplated hereby or the
performance by the Company of any of its obligations hereunder.

     3.4 Reservation and Registration of Shares, Etc. The Company covenants and
agrees that all Warrant Shares which are issuable upon the exercise of this
Warrant will, upon issuance, be validly issued, fully paid and nonassessable and
free from all taxes, liens, security interests, charges and other encumbrances
with respect to the issue thereof, other than taxes in respect of any transfer
occurring contemporaneously with such issue. The Company further covenants and
agrees that, during the Exercise Period, the Company will at all times have
authorized and reserved, and keep available free from preemptive rights, a
sufficient number of shares of Common Stock to provide for the exercise of the
rights represented by this Warrant and will, at its expense, upon each such
reservation of shares, procure such listing of such shares of Common Stock
(subject to issuance or notice of issuance) as then may be required on all stock
exchanges on which the Common Stock is then listed or on Nasdaq.

     4. Exchange, Loss or Destruction of Warrant. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, of such bond or
indemnification as the Company may require, and, in the case of such mutilation,
upon surrender and cancellation of this Warrant, the Company will execute and
deliver a new Warrant of like tenor. The term "Warrant" as used in this
Agreement shall be deemed to include any Warrants issued in substitution or
exchange for this Warrant.

     5. Ownership of Warrant. The Company may deem and treat the person in whose
name this Warrant is registered as the holder and owner hereof (notwithstanding
any notations of ownership or writing hereon made by anyone other than the
Company) for all purposes and shall not be affected by any notice to the
contrary.

     6. Certain Adjustments.

     6.1 Adjustments. The number of Warrant Shares purchasable upon the exercise
of this Warrant and the Exercise Price shall be subject to adjustment as
follows:

     (a) Stock Dividends. If at any time prior to the exercise of this Warrant
in full (i) the Company shall fix a record date for the issuance of any stock
dividend payable in shares of Common Stock or (ii) the number of shares of
Common Stock shall have been increased by a subdivision or split-up of shares of
Common Stock, then, on the record date fixed for the determination of holders
of Common Stock entitled to receive such dividend or immediately after the
effective date of subdivision or split-up, as the case may be, the number of
shares of Common Stock to be delivered upon exercise of this Warrant will be
increased so that the Warrantholder will be entitled to receive the number of
shares of Common Stock that such Warrantholder would have owned immediately
following such action had this Warrant been exercised immediately prior thereto,
and the Exercise Price will be adjusted as provided below in paragraph (f).

                                      -15-

<PAGE>

     (b) Combination of Stock. If at any time prior to the exercise of this
Warrant in full the number of shares of Common Stock outstanding shall have been
decreased by a combination of the outstanding shares of Common Stock, then,
immediately after the effective date of such combination, the number of shares
of Common Stock to be delivered upon exercise of this Warrant will be decreased
so that the Warrantholder thereafter will be entitled to receive the number of
shares of Common Stock that such Warrantholder would have owned immediately
following such action had this Warrant been exercised immediately prior thereto,
and the Exercise Price will be adjusted as provided below in paragraph (f).

     (c) Reorganization, etc. If at any time prior to the exercise of this
Warrant in full any capital reorganization of the Company, or any
reclassifica-tion of the Common Stock, or any consolidation of the Company with
or merger of the Company with or into any other person or any sale, lease or
other transfer of all or substantially all of the assets of the Company to any
other person, shall be effected in such a way that the holders of Common Stock
shall be entitled to receive stock, other securities or assets (whether such
stock, other securities or assets are issued or distributed by the Company or
another person) with respect to or in exchange for Common Stock, then, upon
exercise of this Warrant the Warrantholder shall have the right to receive the
kind and amount of stock, other securities or assets receivable upon such
reorganization, reclassification, consolidation, merger or sale, lease or other
transfer by a holder of the number of shares of Common Stock that such
Warrantholder would have been entitled to receive upon exercise of this Warrant
had this Warrant been exercised immediately before such reorganization,
reclassification, consolidation, merger or sale, lease or other transfer,
subject to adjustments that shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Section 6.

     (d) Fractional Shares. No fractional shares of Common Stock or scrip shall
be issued to any Warrantholder in connection with the exercise of this Warrant.
Instead of any fractional shares of Common Stock that would otherwise be
issuable to such Warrant-holder, the Company will pay to such Warrantholder a
cash adjustment in respect of such fractional interest in an amount equal to
that fractional interest of the fair market value of one share of Common Stock
as of the date of exercise.

     (e) Carryover. Notwithstanding any other provision of this Section 6, no
adjustment shall be made to the number of shares of Common Stock to be delivered
to the Warrantholder (or to the Exercise Price) if such adjustment represents
less than one percent (1%) of the number of shares to be so delivered, but any
lesser adjustment shall be carried forward and shall be made at the time and
together with the next subsequent adjustment which together with any adjustments
so carried forward shall amount to one percent (1%) or more of the number of
shares to be so delivered.

     (f) Exercise Price Adjustment. Whenever the number of Warrant Shares
purchasable upon the exercise of the Warrant is adjusted, as herein provided,
the Exercise Price payable upon the exercise of this Warrant shall be adjusted
by multiplying such Exercise Price immediately prior to such adjustment by a
fraction, of which the numerator shall be the number of Warrant Shares
purchasable upon the exercise of the Warrant immediately prior to such
adjustment, and of which the denominator shall be the number of Warrant Shares
purchasable immediately thereafter.

                                      -16-

<PAGE>

     (g) No Duplicate Adjustments. Notwithstanding anything else to the contrary
contained herein, in no event will an adjustment be made under the provisions of
this Section 6 to the number of Warrant Shares issuable upon exercise of this
Warrant or the Exercise Price for any event if an adjustment having
substantially the same effect to the Warrantholder as any adjustment that
otherwise would be made under the provisions of this Section 6 is made by the
Company for any such event to the number of shares of Common Stock (or other
securities) issuable upon exercise of this Warrant.

     6.2 No Adjustment for Dividends. Except as provided in Section 1 hereof or
Section 6.1 hereof, no adjustment in respect of any dividends shall be made
during the term of the Warrant or upon the exercise of this Warrant.

     6.3 Notice of Adjustment. Whenever the number of Warrant Shares or the
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail by first class, postage prepaid, to the
Warrantholder, notice of such adjustment or adjustments and a certificate of the
chief financial officer of the Company setting forth the number of Warrant
Shares and the Exercise Price of such Warrant Shares after such adjustment,
setting forth a brief statement of the facts requiring such adjustment and
setting forth the computa-tion by which such adjustment was made.

     7. Notices of Corporate Action. In the event of:

     (a) any taking by the Company of a record of the holders of any class of
securities for the purpose of determining the holders thereof who are entitled
to receive any dividend or other distribution, or any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, or

     (b) any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any Change of Control,
or

     (c) any voluntary or involuntary dissolution, liquidation or winding-up of
the Company,

the Company will mail to the Warrantholder a notice specifying (i) the date or
expected date on which any such record is to be taken for the purpose of such
dividend, distribution or right and the amount and character of any such
dividend, distribution or right, and (ii) the date or expected date on which any
such reorganization, reclassification, recapitalization, Change of Control,
dissolution, liquidation or winding-up is to take place and the time, if any
such time is to be fixed, as of which the holders of record of Common Stock (or
other securities) shall be entitled to exchange their shares of Common Stock (or
other securities) for the securities or other property deliverable upon such
reorganization, reclassification, recapitalization, Change of Control,
dissolution, liquidation or winding-up. Such notice shall be mailed at least
ten (10) days prior to the date therein specified, in the case of any date
referred to in the foregoing subdivision (i), and at least ten (10) days prior
to the date therein specified, in the case of the date referred to in the
foregoing subdivision (ii).

     1. Exercise of Warrant.
        --------------------

     1.1 Duration and Exercise of Warrant.
         ---------------------------------

     (a) Cash Exercise.  This Warrant may be exercised by the  Warrantholder  by
         -------------
(i) the  surrender of this  Warrant to the  Company,  with a duly
executed  Exercise Form specifying the number of Warrant Shares to be purchased,
during normal  business hours on any Business Day during the Exercise Period and
(ii) the delivery of payment to the Company,  for the account of the Company, of
the Exercise  Price for the number of Warrant  Shares  specified in the Exercise
Form,  (A) by wire  transfer of  immediately  available  funds to a bank account
specified by the  Company;  (B) by certified  or bank  cashier's  check;  (C) by
cancellation of  indebtedness  under the Credit  Agreement,  or (D) of any other
amount due to the Warrantholder under any other contract (including any purchase
order)  pursuant to which the  Warrantholder  does business with the Company not
paid within  twenty (20) days of when due, or as  otherwise  mutually  agreed to
between the parties. The Company agrees that such Warrant Shares shall be deemed
to be issued to the Warrantholder as the record holder of such Warrant Shares as
of the close of  business  on the date on which  this  Warrant  shall  have been
surrendered  and  payment  made for the  Warrant  Shares as  aforesaid.  A stock
certificate or  certificates  for the Warrant  Shares  specified in the Exercise
Form shall be delivered to the Warrantholder as promptly as practicable. If this
Warrant shall have been exercised  only in part, the Company shall,  at the time
of  delivery  of  the  stock   certificate  or  certificates,   deliver  to  the
Warrantholder  a new Warrant  evidencing  the rights to purchase  the  remaining
Warrant Shares,  which new Warrant shall in all other respects be identical with
this Warrant.  No adjustments  shall be made on Warrant  Shares  issuable on the
exercise of this  Warrant for any cash  dividends  paid or payable to holders of
record of Common Stock prior to the date as of which the Warrantholder  shall be
deemed to be the record holder of such Warrant Shares.

     (b) Net Issue  Exercise.  In lieu of  exercising  this Warrant  pursuant to
         -------------------
Section  1.1(a),  this  Warrant  may  be  exercised  by the
Warrantholder  by the  surrender  of this  Warrant to the  Company,  with a duly
executed  Exercise Form marked to reflect Net Issue  Exercise and specifying the
number of Warrant  Shares to be purchased,  during normal  business hours on any
Business Day during the Exercise  Period.  The Company  agrees that such Warrant
Shares shall be deemed to be issued to the Warrantholder as the record holder of
such  Warrant  Shares  as of the  close of  business  on the date on which  this
Warrant  shall have been  surrendered  as  aforesaid.  Upon such  exercise,  the
Warrantholder  shall be  entitled to receive  shares  equal to the value of this
Warrant  (or the  portion  hereof  being  exercised)  computed as of the date of
surrender of this Warrant to the Company using the following formula:

                      X = Y x (A-B)
                          ---------
                              A

Where X = the number of shares of Common Stock to be issued to Warrantholder
          under this Section 1.1(b);

      Y = the number of shares of Common Stock otherwise purchasable under
          this Warrant (at the date of such calculation);

                                      -2-

<PAGE>


     A = the fair market value of one share of Common Stock (at the date of
         such calculation);

     B = the Exercise Price (as adjusted to the date of such calculation).

     (c) Fair  Market  Value.  For  purposes  of  Section  1.1(b)  "fair  market
         --------------------
value" of one share of Common Stock shall mean:


     (i) the  average  closing  price  per  share  of the  Common  Stock  on the
principal  national  securities  exchange on which the Common Stock is listed or
admitted  to trading for the ten (10)  Trading Day period  ending on the date of
exercise, or,

     (ii) if not  listed  or  traded  on any such  exchange,  the  average  last
reported sales price per share of the Common Stock on the Nasdaq National Market
or The Nasdaq SmallCap Market (collectively,  "Nasdaq") for the ten (10) Trading
Day period ending on the date of exercise, or,

     (iii) if not listed or traded on any such  exchange or Nasdaq,  the average
of the  mean of the bid and  asked  prices  per  share  of the  Common  Stock as
reported in the OTC Bulletin Board or, if not so reported,  in the "pink sheets"
published by the National  Quotation  Bureau,  Inc. for the ten (10) Trading Day
period ending on the date of exercise, or,

     (iv) if such quotations are not available,  the fair market value per share
of the Common  Stock on the date such  notice  was  received  by the  Company as
reasonably determined by the Board of Directors of the Company.

     1.2 Number of Warrant Shares.  This Warrant shall entitle the Warrantholder
         ------------------------
to purchase 2,236,198 shares of Common Stock.

     1.3 Exercise Price.  The Exercise  Price shall be equal to $4.471875  (the
         ---------------
"Exercise Price"). From and after the issuance of this Warrant,
the Exercise Price shall be adjusted in accordance with Section 6 hereof.

     1.4 Term of Warrant and Exercisability.
         -----------------------------------

     (a) Term of Warrant.  This Warrant shall terminate on the later of (i) June
         ---------------
21, 2000; (ii) the date on which the indebtedness of the Company to the
Warrantholder under the Credit Agreement is paid in full;  provided, however,
                                                           -----------------
that  this  Warrant  shall  terminate  upon  the
consummation  of an S3  Acquisition.  Nothing in this Section  1.4(a),  however,
shall  require S3 to advance any  portion of the third Loan  pursuant to Section
3.4 of the Credit Agreement,  and S3 shall not have any liability for failing to
do so. The  parties'  rights and  obligations  under  Sections 2, 8 and 9 hereof
shall survive the termination of this Warrant.

(b) Exercisability. Notwithstanding anything to the contrary herein, this
    --------------
Warrant shall become immediately exercisable, in whole or in part, as to one
hundred percent (100%) of the Warrant Shares concurrently with the advance by S3
of the third Loan to Diamond pursuant


                                      -3-

<PAGE>


to Section 3.4 of the Credit Agreement. This Warrant shall also become
immediately exercisable, in whole or in part, as to one hundred percent (100%)
of the Warrant Shares if (i) Diamond materially breaches its obligations under
the Credit Agreement for so long as such breach shall be continuing; (ii) S3
does not advance the third Loan to Diamond on July 1, 1999 pursuant to Section
3.4 of the Credit Agreement, because any one of the conditions to the third Loan
set forth in Section 3.4(b), Section 3.4(c), Section 3.4(d) (unless such failure
is due to a failure by Finova to consent to the terms of the Credit Agreement),
or Section 3.4(e), of the Credit Agreement is not satisfied on or prior to such
date, or (iii) prior to the time that S3 advances the third Loan to Diamond
pursuant to Section 3.4 of the Credit Agreement, Diamond receives a Superior
Proposal (as defined in the Merger Agreement) in respect of Diamond from a third
party Person and executes a definitive agreement for a transaction that, if
consummated, would constitute a Change of Control of Diamond. If this Warrant
has become exercisable as to one hundred percent (100%) of the Warrant Shares
pursuant to the provisions of this Section 1.4(b), and S3 receives a Superior
Proposal (as defined in the Merger Agreement) in respect of S3 from a third
party Person for a transaction that, if consummated, would constitute an S3
Acquisition, then this Warrant shall cease to be exercisable as to one hundred
percent (100%) of the Warrant Shares until and unless S3 terminates discussions
with such third party Person (without consummation of the transaction that would
constitute an S3 Acquisition), irrespective of whether S3 has executed a
definitive agreement with such third party Person for a transaction that would
constitute an S3 Acquisition; provided, however, that if prior to the time S3
receives a Superior Proposal (as ----------------- defined in the Merger
Agreement) in respect of S3 from a third party Person for a transaction that, if
consummated, would constitute an S3 Acquisition, Diamond has already received a
Superior Proposal (as defined in the Merger Agreement) in respect of Diamond
from a third party Person for a transaction that, if consummated, would
constitute a Change of Control of Diamond, this sentence shall not apply, and
this Warrant shall remain exercisable as to one hundred percent (100%) of the
Warrant Shares unless and until Diamond terminates discussions with such third
party Person (without consummation of the transaction that would constitute a
Change in Control of Diamond) irrespective of whether Diamond has executed a
definitive agreement with such third party Person for a transaction that would
constitute a Diamond Change in Control. Unless this Warrant has become
exercisable as to the Warrant Shares pursuant to the provisions of this Section
1.4(b), this Warrant shall not be exercisable as to the Warrant Shares.

     1.5 Payment of Taxes. The issuance of certificates for Warrant Shares shall
         ----------------
be made  without  charge  to the  Warrantholder  for any stock
transfer or other issuance tax in respect thereto;  provided,  however, that the
                                                    ------------------
Warrantholder shall be required to pay any and all taxes which
may be payable in respect of any transfer  involved in the issuance and delivery
of any  certificate  in a name  other  than  that of the then  Warrantholder  as
reflected upon the books of the Company.

    1.6 Information. Upon receipt of a written request from a Warrantholder,
        -----------
the Company agrees to deliver promptly to such Warrantholder a copy of its
current publicly available financial statements and to provide such other
publicly available information concerning the Company as such Warrantholder may
reasonably request (if electronic access to such information via EDGAR is not
then generally available to the public) in order to assist the Warrantholder in
evaluating the merits and risks of exercising the Warrant and to make an
informed investment decision in connection with such exercise.

Holder made within ten (10) days after receipt of any such notice (which request
shall specify the Registrable Securities intended to be disposed of by such
Holder), the Company shall include in the Registration Statement the Registrable
Securities which the Company has been so requested to register by the Holders
thereof and the Company shall keep such registration statement in effect and
maintain compliance with each federal and state law or regulation for the period
necessary for such Holder to effect the proposed sale or other disposition (but
in no event for a period greater than ninety (90) days).

     (b) Withdrawal of Piggyback Registration by Company. If, at any time after
         -----------------------------------------------
giving written notice of its intention to register any securities in a Piggyback
Registration but prior to the effective date of the related Registration
Statement, the Company shall determine for any reason not to register such
securities, the Company shall give notice of such determination to each Holder
and, thereupon, shall be relieved of its obligation to register any Registrable
Securities in connection with such Piggyback Registration. All best efforts
obligations of the Company pursuant to Section 2.4 shall cease if the Company
determines to terminate prior to such effective date any registration where
Registrable Securities are being registered pursuant to this Section 2.1.

     (c) Piggyback Registration of Underwritten Public Offerings. If a Piggyback
         -------------------------------------------------------
Registration involves an offering by or through underwriters, then (i) all
Holders requesting to have their Registrable securities included in the
Company's Registration Statement must sell their Registrable Securities to the
underwriters selected by the Company on the same terms and conditions as apply
to other selling shareholders and (ii) any Holder requesting to have his or its
Registrable Securities included in such Registration Statement may elect in
writing, not later than seven (7) Business Days prior to the effectiveness of
the Registration Statement filed in connection with such registration, not to
have his or its Registrable Securities so included in connection with such
registration.

     (d) Payment of Registration Expenses for Piggyback Registration. The
         -----------------------------------------------------------
Company shall pay all Registration Expenses in connection with each registration
of Registrable Securities requested pursuant to a Piggyback Registration Right
contained in this Section 2.1.

     (e) Priority in Piggyback Registration. If a Piggyback Registration
         ----------------------------------
involves an offering by or through underwriters, the Company, except as
otherwise provided herein, shall not be required to include Registrable
Securities therein if and to the extent the underwriter managing the offering
reasonably believes in good faith and advises each Holder requesting to have
Registrable Securities included in the Company's Registration Statement that
such inclusion would materially adversely affect such offering; provided that
(i) if other selling shareholders who are employees, officers, directors or
other affiliates of the Company have requested registration of securities in the
proposed offering, the Company will reduce or eliminate such other selling
shareholders' securities before any reduction or elimination of Registrable
Securities; and (ii) any such reduction or elimination (after taking into
account the effect of clause (i)) shall be pro rata to all other holders of the
securities of the Company exercising "Piggyback Registration Rights" similar to
those set forth herein in proportion to the respective number of shares they
have requested to be registered.

     2.2 Demand Registration.
         --------------------

     (a) Request for Registration. Unless this Warrant is exercised pursuant to
         ------------------------
Section 1.1(b) hereof, if, at any time prior to the fifth anniversary of the
date hereof, Holders holding the greater of (i) at least twenty-five percent
(25%) of the combined total of Warrant Shares issuable and Warrant Shares
outstanding pursuant to the Second Warrant and any prior or subsequent warrant
issued by Diamond to S3 or (ii) one hundred percent (100%) of such shares issued
or issuable pursuant to the First Warrant, at such time request that the Company
file a registration statement on Form S-3 (or Form S-1 if Form S-3 is not then
available to the Company) under the Securities Act, as soon as practicable
thereafter the Company shall use its commercially reasonable efforts to file a
registration statement with respect to all Warrant Shares that it has been so
requested to include (so long as such Warrant Shares represent the greater of
the amount set forth in clause (i) or clause (ii) above)(the "Demand
Registration") and obtain the effectiveness thereof, and to take all other
action necessary under any federal or state law or regulation to permit the
Warrant Shares that are held and/or that may be acquired upon the exercise of
the Warrants specified in the notices of the Holders or holders thereof to be
sold or otherwise disposed of, and the Company shall maintain such compliance
with each such federal and state law and regulation for the period necessary for
such Holders or holders to effect the proposed sale or other disposition, which
period shall be not less than thirty (30) days; provided, however, the Company
shall be entitled to defer such registration for a period of up to forty-five
(45) days if and to the extent that its Board of Directors shall determine that
such registration would interfere with a pending corporate transaction. The
Company shall also promptly give written notice to the Holders and the holders
of any other Warrants and/or the holders of any Warrant Shares who or that have
not made a request to the Company pursuant to the provisions of this Section
2.2(a) of its intention to effect any required registration or qualification,
and shall use its commercially reasonable efforts to effect as expeditiously as
possible such registration or qualification of all such other Warrant Shares
that are then held and/or that may be acquired upon the exercise of the
Warrants, the Holder or holders of which have requested such registration or
qualification within fifteen (15) days after such notice has been given by the
Company. The Company shall be required to effect a registration or qualification
pursuant to this Section 2.2(a) on a total of one (1) occasion.

                                      -6-

     (b) Payment of Registration Expenses for Demand Registration. The Company
         ---------------------------------------------------------
shall pay all Registration Expenses in connection with the Demand Registration.

     (c) Selection of Underwriters. If the Demand Registration is requested to
         --------------------------
be in the form of an underwritten offering, the managing underwriter shall be
selected by the Holders of a majority of the Warrant Shares to be registered.
Such selection shall be subject to the Company's consent, which consent shall
not be unreasonably withheld.

     (d) Procedure for Requesting Demand Registration. Any request for a Demand
         ---------------------------------------------
Registration shall specify the aggregate number of the Registrable Securities
proposed to be sold and the intended method of disposition. Within ten (10) days
after receipt of such a request the Company will give written notice of such
registration request to all Holders, and the Company will include in such
registration all Registrable Securities with respect to which the Company has
received written requests for inclusion therein within fifteen (15) Business
Days after the date on which such notice is given by the Company. Each such
request shall also specify the aggregate number of Registrable Securities to be
registered and the intended method of disposition thereof.

     2.3 Registration Procedures. If and whenever the Company is required to
         ------------------------
use its commercially reasonable efforts to take action pursuant to any federal
or state law or regulation to permit the sale or other disposition of any
Registrable Securities that are then held or that may be acquired upon exercise

Securities under the Securities Act as provided in this Article 2, the Company
shall, as expeditiously as practicable:

such Registration Statements to become effective; provided that before filing a
Registration Statement or Prospectus or any amendment or supplements thereto,
including documents incorporated by reference after the initial filing of any

documents will be subject to the review of such Holders and underwriters;

     (b) prepare and file with the SEC such amendments and post-effective

not misleading;

     (d) make every reasonable effort to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement at the earliest

     (e) if reasonably requested by the managing underwriters, immediately

Holders of Registrable Securities and the underwriters, if any, in connection
with the offering and sale of the Registrable Securities covered by such
Prospectus or any amendment or supplement thereto;

     (h) prior to any public offering of Registrable Securities, cooperate with

their respective counsel in connection with the registration or qualification of
such Registrable Securities for offer and sale

                                      -8-

<PAGE>

under the securities or Blue Sky laws of such jurisdictions within the United
States as any selling Holder or underwriter reasonably requests in writing, keep
each such registration or qualification effective during the period such
Registration Statement is required to be kept effective and do any and all other
acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Registrable Securities covered by the applicable

     (j) use its commercially reasonable efforts to cause the Registrable
Securities covered by the applicable Registration Statement to be registered
with or approved by such other governmental agencies or authorities within the
United States as may be necessary to enable the seller or sellers thereof or the
underwriters, if any, to consummate the disposition of such Registrable
Securities;

     (k) upon the occurrence of any event contemplated by Section 2.3(c)(vi)
above, prepare a supplement or post-effective amendment to the applicable
Registration Statement or related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter

     2.4 Indemnification.
         ----------------

     (a) Indemnification by Company. In connection with each Registration
         ---------------------------
Statement relating to disposition of Registrable Securities, the Company shall
indemnify and hold harmless each Holder and each underwriter of Registrable
Securities and each Person, if any, who controls such Holder or underwriter
(within the meaning of section 15 of the Securities Act or section 20 of the
Exchange Act) against any and all losses, claims, damages and liabilities, joint
or several (including any reasonable investigation, legal and other expenses
incurred in connection with, and any amount paid in settlement of any action,
suit or proceeding or any claim asserted), to which they, or any of them, may
become subject under the Securities Act, the Exchange Act or other federal or
state law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities arise out of or are based upon any untrue
statement or alleged

                                      -11-

<PAGE>

untrue statement of a material fact contained in any Registration Statement,
Prospectus or preliminary Prospectus or any amendment thereof or supplement
thereto, or arise out of or are based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading; provided, however, that such indemnity
shall not inure to the benefit of any Holder or underwriter (or any person
controlling such Holder or underwriter within the meaning of section 15 of the
Securities Act or section 20 of the Exchange Act) on account of any losses,
claims, damages or liabilities arising from the sale of the Registrable
Securities if such untrue statement or omission or alleged untrue statement or
omission was made in such Registration Statement, Prospectus or preliminary
Prospectus, or such amendment or supplement, in reliance upon and in conformity
with information furnished in writing to the Company by such Holder or
underwriter specifically for use therein; provided, further, that the Company
shall not be liable to such Holder or any underwriter (or any person controlling
such Holder or underwriter) with respect to any such untrue statement or alleged
untrue statement or omission made in any preliminary Prospectus that is
corrected in the Prospectus (or any amendment or supplement thereto) if the
person asserting any such loss, claim, damage or liability purchased shares of
the Common Stock from such Holder or underwriter but was not given a copy of the
Prospectus (as amended or supplemented) in any case where such delivery of the
Prospectus (as amended or supplemented) was required by the Securities Act. The
Company shall also indemnify selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, their
officers and directors and each Person who controls such Persons (within the
meaning of section 15 of the Securities Act or section 20 of the Exchange Act)
to the same extent as provided above with respect to the indemnification of the
Holders of Registrable Securities, if requested. This indemnity agreement shall
be in addition to any liability which the Company may otherwise have.

     (b) Indemnification by Holder. In connection with each Registration
         --------------------------
Statement, each Holder shall indemnify, to the same extent as the
indemnification provided by the Company in Section 2.4(a), the Company, its
directors and each officer who signs the Registration Statement and each Person
who controls the Company (within the meaning of section 15 of the Securities Act
and section 20 of the Exchange Act) but only insofar as such losses, claims,
damages and liabilities arise out of or are based upon any untrue statement or
omission or alleged untrue statement or omission which was made in the
Registration Statement, the Prospectus or preliminary Prospectus or any
amendment thereof or supplement thereto, in reliance upon and in conformity with
information furnished in writing by such Holder to the Company specifically for
use therein. In no event shall the liability of any selling Holder of
Registrable Securities hereunder be greater in amount than the dollar amount of
the net proceeds received by such Holder upon the sale of the Registrable
Securities giving rise to such indemnification obligation. The Company shall be
entitled to receive indemnities from underwriters, selling brokers, dealer
managers and similar securities industry professionals participating in the
distribution, to the same extent as provided above, with respect to information
so furnished in writing by such Persons specifically for inclusion in any
Prospectus, Registration Statement or preliminary Prospectus or any amendment
thereof or supplement thereto.

     (c) Conduct of Indemnification Procedure. Any party that proposes to assert
         -------------------------------------
the right to be indemnified hereunder will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim is to be made against an

                                      -11-

<PAGE>

indemnifying party or parties under this Section, notify each such indemnifying
party of the commencement of such action, suit or proceeding, enclosing a copy
of all papers served. No indemnification provided for in Section 2.4(a) or
2.4(b) shall be available to any party who shall fail to give notice as provided
in this Section 2.4(c) if the party to whom notice was not given was unaware of
the proceeding to which such notice would have related and was materially
prejudiced by the failure to give such notice, but the omission so to notify
such indemnifying party of any such action, suit or proceeding shall not relieve
it from any liability that it may have to any indemnified party for contribution
otherwise than under this Section. In case any such action, suit or proceeding
shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate in, and, to the extent that it shall wish, jointly with
any other indemnifying party similarly notified, to assume the defense thereof,
with counsel satisfactory to such indemnified party, and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof and the approval by the indemnified party of such counsel, the
indemnifying party shall not be liable to such indemnified party for any legal
or other expenses, except as provided below and except for the reasonable costs
of investigation subsequently incurred by such indemnified party in connection
with the defense thereof. The indemnified party shall have the right to employ
its counsel in any such action, but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the employment of counsel
by such indemnified party has been authorized in writing by the indemnifying
parties, (ii) the indemnified party shall have reasonably concluded that there
may be a conflict of interest between the indemnifying parties and the
indemnified party in the conduct of the defense of such action (in which case
the indemnifying parties shall not have the right to direct the defense of such
action on behalf of the indemnified party) or (iii) the indemnifying parties
shall not have employed counsel to assume the defense of such action within a
reasonable time after notice of the commencement thereof, in each of which cases
the fees and expenses of counsel shall be at the expense of the indemnifying
parties. An indemnified party shall not be liable for any settlement of any
action, suit, proceeding or claim effected without its written consent.

     (d) Contribution. In connection with each Registration Statement relating
         -------------
to the disposition of Registrable Securities, if the indemnification provided
for in Section 2.4(a) or 2.4(b) hereof is unavailable to an indemnified party
thereunder in respect to any losses, claims, damages or liabilities referred to
therein, then the indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in paragraphs (a) or (b) of this Section 2.4 in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such losses, claims, damages
or liabilities, or actions in respect thereof, as well as any other relevant
equitable considerations. 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 the indemnified party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. 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 paragraph
(d) shall be deemed to include any legal or other expenses

                                      -12-

<PAGE>

reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim.

     (e) Underwriting Agreement to Control. Notwithstanding the foregoing
         ----------------------------------
provisions of this Section 2.4, to the extent that the provisions on
indemnification and contribution contained in any underwriting agreement entered
into in connection with the underwritten public offering of the Registrable
Securities are in conflict with the foregoing provisions, the provisions in such
underwriting agreement shall control.

     (f) Specific Performance. The Company and the Holder acknowledge that
         ---------------------
remedies at law for the enforcement of this Section 2.4 may be inadequate and
intend that this Section 2.4 shall be specifically enforceable.

     (g) Survival of Obligations. The obligations of the Company and the Holder
         ------------------------
under this Section 2.4 shall survive the completion of any offering of
Registrable Securities pursuant to a Registration Statement under this Article
2, and otherwise.

     2.5 Reports Under Securities Exchange Act of 1934. With a view to making
         ----------------------------------------------
available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:

     (a) make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times;

     (b) file with the SEC in a timely manner all reports and other documents
required of the Company under the Securities Act and the Exchange Act; and

     (c) furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144, the Securities
Act and the Exchange Act, or that it qualifies as a registrant whose securities
may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a
copy of the most recent annual or quarterly report of the Company and such other
reports and documents so filed by the Company and (iii) such other information
as may be reasonably requested in availing any Holder of any rule or regulation
of the SEC which permits the selling of any such securities without registration
or pursuant to such form.

     2.6 Restrictions on Transfer; Compliance with Securities Laws. This Warrant
         ----------------------------------------------------------
and the Warrant Shares issued upon the exercise of the Warrant may not be
transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and transferee
(including the delivery of investment representation letters and legal opinions
reasonably satisfactory to the Company, if such are requested by the Company).
The Warrantholder, by acceptance hereof, acknowledges that this Warrant and the
Warrant Shares to be issued upon exercise hereof are being acquired solely for
the Warrantholder's own account and not as a nominee for any other party, and
for investment, and that the Warrantholder will not offer, sell or otherwise
dispose of any Warrant Shares to be issued upon exercise hereof except

                                      -13-

<PAGE>


under circumstances that will not result in a violation of the Securities Act or
any state securities laws. Upon exercise of this Warrant, the Warrantholder
shall, if requested by the Company, confirm in writing, in a form satisfactory
to the Company, that the Warrant Shares so purchased are being acquired solely
for the Warrantholder's own account and not as a nominee for any other party,
for investment, and not with a view toward distribution or resale.

     2.7 Restrictive Legends. This Warrant shall (and each Warrant issued upon
         --------------------
transfer in whole or in part of this Warrant pursuant to this Section 2 or
issued in substitution for this Warrant pursuant to Section 4 shall) be stamped
or otherwise imprinted with a legend in substantially the following form:

<PAGE>

necessary corporate action on the part of the Company. This Warrant has been
duly and validly executed and delivered by the Company and constitutes a valid
and binding obligation of the Company enforceable against the Company in
accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting creditors' rights generally, and by general equitable principles.

     3.2 Authority to Issue Shares. The Company has taken all necessary

corporate action to authorize and reserve and permit it to issue, and at all

     3.3 No Conflict; Required Filings and Consents.
         -------------------------------------------

performance by the Company of its obligations hereunder or the consummation by
the Company of the transactions contemplated hereby, except for (i) compliance

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

exchanges on which the Common Stock is then listed or on Nasdaq.

<PAGE>

     4. Exchange, Loss or Destruction of Warrant. Upon receipt by the Company of
        -----------------------------------------
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, of such bond or
indemnification as the Company may require, and, in the case of such mutilation,
upon surrender and cancellation of this Warrant, the Company will execute and
deliver a new Warrant of like tenor. The term "Warrant" as used in this
Agreement shall be deemed to include any Warrants issued in substitution or
exchange for this Warrant.

     5. Ownership of Warrant. The Company may deem and treat the person in whose
        ---------------------
name this Warrant is registered as the holder and owner hereof (notwithstanding
any notations of ownership or writing hereon made by anyone other than the
Company) for all purposes and shall not be affected by any notice to the
contrary.

     6. Certain Adjustments.
        --------------------

     6.1 Adjustments. The number of Warrant Shares purchasable upon the exercise
         ------------
of this Warrant and the Exercise Price shall be subject to adjustment as
follows:

     (a) Stock Dividends. If at any time prior to the exercise of this Warrant
         ----------------
in full (i) the Company shall fix a record date for the issuance of any stock
dividend payable in shares of Common Stock or (ii) the number of shares of
Common Stock shall have been increased by a subdivision or split-up of shares of
Common Stock, then, on the record date fixed for the determination of holders of
Common Stock entitled to receive such dividend or immediately after the
effective date of subdivision or split-up, as the case may be, the number of
shares of Common Stock to be delivered upon exercise of this Warrant will be
increased so that the Warrantholder will be entitled to receive the number of
shares of Common Stock that such Warrantholder would have owned immediately
following such action had this Warrant been exercised immediately prior thereto,
and the Exercise Price will be adjusted as provided below in paragraph (f).

     (b) Combination of Stock. If at any time prior to the exercise of this
         ---------------------
Warrant in full the number of shares of Common Stock outstanding shall have been
decreased by a combination of the outstanding shares of Common Stock, then,
immediately after the effective date of such combination, the number of shares
of Common Stock to be delivered upon exercise of this Warrant will be decreased
so that the Warrantholder thereafter will be entitled to receive the number of
shares of Common Stock that such Warrantholder would have owned immediately
following such action had this Warrant been exercised immediately prior thereto,
and the Exercise Price will be adjusted as provided below in paragraph (f).

     (c) Reorganization, etc. If at any time prior to the exercise of this
         --------------------
Warrant in full any capital reorganization of the Company, or any
reclassification of the Common Stock, or any consolidation of the Company with
or merger of the Company with or into any other person or any sale, lease or
other transfer of all or substantially all of the assets of the Company to any
other person, shall be effected in such a way that the holders of Common Stock
shall be entitled to receive stock, other securities or assets (whether such
stock, other securities or assets are issued or distributed by the Company or
another person) with respect to or in exchange for Common Stock, then, upon
exercise of this Warrant the Warrantholder shall have the right to receive the
kind and amount of stock, other securities or assets receivable upon such
reorgani-

                                      -16-

<PAGE>

zation, reclassification, consolidation, merger or sale, lease or other transfer
by a holder of the number of shares of Common Stock that such Warrantholder
would have been entitled to receive upon exercise of this Warrant had this
Warrant been exercised immediately before such reorganization, reclassification,
consolidation, merger or sale, lease or other transfer, subject to adjustments
that shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 6.

     (d) Fractional Shares. No fractional shares of Common Stock or scrip shall
         ------------------
be issued to any Warrantholder in connection with the exercise of this Warrant.
Instead of any fractional shares of Common Stock that would otherwise be
issuable to such Warrantholder, the Company will pay to such Warrantholder a
cash adjustment in respect of such fractional interest in an amount equal to
that fractional interest of the fair market value of one share of Common Stock
as of the date of exercise.

     (e) Carryover. Notwithstanding any other provision of this Section 6, no
         ----------
adjustment shall be made to the number of shares of Common Stock to be delivered
to the Warrantholder (or to the Exercise Price) if such adjustment represents
less than one percent (1%) of the number of shares to be so delivered, but any
lesser adjustment shall be carried forward and shall be made at the time and
together with the next subsequent adjustment which together with any adjustments
so carried forward shall amount to one percent (1%) or more of the number of
shares to be so delivered.

     (f) Exercise Price Adjustment. Whenever the number of Warrant Shares
         --------------------------
purchasable upon the exercise of the Warrant is adjusted, as herein provided,
the Exercise Price payable upon the exercise of this Warrant shall be adjusted
by multiplying such Exercise Price immediately prior to such adjustment by a
fraction, of which the numerator shall be the number of Warrant Shares
purchasable upon the exercise of the Warrant immediately prior to such
adjustment, and of which the denominator shall be the number of Warrant Shares
purchasable immediately thereafter.

     (g) No Duplicate Adjustments. Notwithstanding anything else to the contrary
         -------------------------
contained herein, in no event will an adjustment be made under the provisions of
this Section 6 to the number of Warrant Shares issuable upon exercise of this
Warrant or the Exercise Price for any event if an adjustment having
substantially the same effect to the Warrantholder as any adjustment that
otherwise would be made under the provisions of this Section 6 is made by the
Company for any such event to the number of shares of Common Stock (or other
securities) issuable upon exercise of this Warrant.

     6.2 No Adjustment for Dividends. Except as provided in Section 1 hereof or
         ----------------------------
Section 6.1 hereof, no adjustment in respect of any dividends shall be made
during the term of the Warrant or upon the exercise of this Warrant.

     6.3 Notice of Adjustment. Whenever the number of Warrant Shares or the
         ---------------------
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail by first class, postage prepaid, to the
Warrantholder, notice of such adjustment or adjustments and a certificate of the
chief financial officer of the Company setting forth the number of Warrant
Shares and the Exercise Price of such Warrant Shares after such adjustment,
setting forth a brief

                                      -17-

<PAGE>

statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made.

     7. Notices of Corporate Action. In the event of:
        ----------------------------

     (a) any taking by the Company of a record of the holders of any class of
securities for the purpose of determining the holders thereof who are entitled
to receive any dividend or other distribution, or any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, or

     (b) any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any Change of Control,
or

     (c) any voluntary or involuntary dissolution, liquidation or winding-up of
the Company,

the Company will mail to the Warrantholder a notice specifying (i) the date or
expected date on which any such record is to be taken for the purpose of such
dividend, distribution or right and the amount and character of any such
dividend, distribution or right, and (ii) the date or expected date on which any
such reorganization, reclassification, recapitalization, Change of Control,
dissolution, liquidation or winding-up is to take place and the time, if any
such time is to be fixed, as of which the holders of record of Common Stock (or
other securities) shall be entitled to exchange their shares of Common Stock (or
other securities) for the securities or other property deliverable upon such
reorganization, reclassification, recapitalization, Change of Control,
dissolution, liquidation or winding-up. Such notice shall be mailed at least ten
(10) days prior to the date therein specified, in the case of any date referred
to in the foregoing subdivision (i), and at least ten (10) days prior to the
date therein specified, in the case of the date referred to in the foregoing
subdivision (ii).

         ------------
following terms have the following respective meanings:
