business by the employees and consultants of the Company as now conducted, nor

them, and are not in default in any material respect, under any material
contract, commitment or instrument, and no event or condition has occurred
which, with the giving of notice or passage of time, or both, would constitute
such a default.  Neither the Company nor any subsidiary is under any obligation
that cannot readily be performed by it on time and without undue or unusual
expenditure of money or effort.  All parties having material contracts or
commitments with the Company or any subsidiary are in compliance therewith in
all material respects.  Exhibit K to this Agreement contains an accurate list of

requested, the Company shall reasonably cooperate with the efforts of such
foreign investor to obtain a "qualifying statement," within the meaning of IRC
Section 1445(b) (4) or such other documents as would excuse a transferee of a

     Section 3.  Representations, Warranties and Agreements of the Investor.
                 ----------------------------------------------------------  
The Investor:

          (a) Represents and warrants to the Company that:

                                      -8-

 
               (i) it is a corporation as indicated on the signature page of
this Agreement:

               (ii) the execution, delivery and performance by it of this
Agreement have been duly authorized;

               (iii)  this Agreement constitutes a valid and binding obligation
of the Investor;

          (iv) no person or firm has, or will have, as a result of any act or
omission by the Investor or anyone acting on behalf of the Investor, any right,
interest or valid claim against the Company or any subsidiary, for any
commission, fee or other compensation as a finder or broker or in any similar
capacity;

          (v) the Investor is acquiring the Securities being purchased by it for
its own account for investment and not with a view to, or for sale in connection
with, distribution of any of the Securities; and

          (vi) the Investor is an "accredited investor" as that term is defined
in Rule 501(A)(1), (2), (3) or (7) under the Securities Act and that it is able
to bear the economic risk of its investment.

          (b) Agrees that it will not sell or otherwise transfer any of the
Securities, except in accordance with the Securities Act and all applicable
state securities laws, and that prior to any transfer (other than pursuant to an
effective registration under that Act) it will furnish to the Company a written
opinion of counsel, reasonably satisfactory in form and substance to the
Company, to the effect that registration under the Securities Act is not
required, and all requisite action has been taken, under all applicable state
securities laws, in connection with the proposed transfer.  The Company will
promptly review any such opinion to determine whether it is reasonably
satisfactory in form and substance.

          (c) Acknowledges that it is aware that it will not be entitled to make
any public offer or public sale of any of the Securities for an indefinite
period unless those Securities are then registered under the Securities Act.
Although it may be possible in the future to make limited public sales of the
Securities without registration in reliance on Rule 144 under that Act, Rule 144
is not now available and there is no assurance that it will become available for
this purpose.  Accordingly, the Investor understands that it must bear the
economic risk of its investment in the Securities for an indefinite period.

          (d) Acknowledges that it has been furnished access to the business
records of the Company (including any subsidiaries) and such additional
information and documents as the Investor has requested, and has been given the
opportunity to meet with Company officials and, to have such persons answer
questions regarding the Company's affairs and condition.

          (e) Acknowledges its understanding that the certificates evidencing
the Securities (other than Securities that shall have been transferred pursuant
to an effective 

                                      -9-

 
registration statement) will bear legends substantially in the following form
until the Company's counsel determines that the legends are no longer advisable:

          "[The shares evidenced by this certificate have] [This Warrant has]
          not been registered under the Securities Act of 1933, as amended, and
          must be held indefinitely unless [they are] [it is] transferred
          pursuant to an effective registration statement under that Act,
          pursuant to Rule 144 or l44A, or after receipt of an opinion of
          counsel satisfactory to the Company that registration is not
          required."

          "[The shares evidenced by this certificate are] [This Warrant is]
          subject to certain agreements contained in the Purchase Agreement
          dated as of September 6, 1994 among the Company and [Investor], a copy
          of which is on file with the Secretary of the Company."

The appropriate stop-transfer orders will be noted on the Company's stock and
warrant records with respect to all Securities so legended with the first
legend.

          (f) Agrees that it shall hold in confidence any confidential
information about the Company that the Investor has received or hereafter
receives pursuant to any provision of this Agreement under circumstances
indicating the confidentiality of such information unless (i) such information
shall have been publicly disclosed other than as a result of any wrongful action
of Investor, or (ii) Investor independently develops or is aware of such
information.

          (g)  (i)  Agrees for itself, its affiliates and any transferee of
Investor which is obligated under this Section 3(g)(i), that without the prior
written consent of the Company, it will not directly or indirectly increase its
holdings of capital stock of the Company or any security convertible into or
exercisable or exchangeable for capital stock of the Company ("Capital
Holdings") such that, after giving effect to the increase in such holdings, the
Investor will hold securities representing a number of Common Stock Equivalents
(as hereinafter defined) greater than 25% of the Common Stock Equivalents
represented by securities then outstanding (the "Holding Limit"); provided,
                                                                  -------- 
however, that the Investor may increase its holdings above the foregoing limit
- -------                                                                       
as a result of an acquisition of securities of the Company pursuant to a merger
or a purchase of securities made pursuant to a plan of merger or an offer
simultaneously made by the Investor to acquire the Company pursuant to a merger
or to purchase all of the capital stock held by all holders of capital stock of
the Company which in either case is accepted by the holders of securities
representing two-thirds of the Common Stock Equivalents then outstanding (which
for purposes of said computation shall include the Common Stock Equivalents held
by the Investor).  Notwithstanding the foregoing restriction, the Investor may
increase its Capital Holdings above 25% upon exercise of the Warrant solely and
to the extent that at the date of exercise of the Warrant the outstanding Common
Stock Equivalents against which the 25% limitation is calculated are less than
16,027,668 by reason that from the date hereof through the date of exercise
either (i) the Company has repurchased or redeemed Common Stock Equivalents, or
(ii) vested options outstanding on the date hereof shall not have been exercised
or (iii) both of (i) and (ii).

                                      -10-

 
          (ii) The agreement set forth in Section 3(g)(i) shall expire upon the
earlier of the tenth anniversary of the date of this Agreement or the second
anniversary of the date on which the Company shall have first issued its
securities upon the consummation of an initial public offering made pursuant to
a registration statement declared effective under the Securities Act (an "IPO");
provided, however, that if the Investor (or any transferee of securities which
- --------  -------                                                             
is bound by the provisions of Section 3(g)(i)) shall transfer securities of the
Company and such transferee is bound by the provisions of Section 3(g)(i), then,
as to such transferee the agreements set forth in Section 3(g)(i) shall expire
on the earlier of the tenth anniversary of the date of this Agreement or on the
date the Company first issues its equity securities in an IPO.

          (iii)  For purposes of this Agreement the term "Common Stock
Equivalents" shall mean Common Stock and securities which are then (without
payment of any additional consideration other than the tender of the security)
convertible into or exchangeable for Common Stock.  Each share of Common Stock
shall represent one Common Stock Equivalent.  The number of Common Stock
Equivalents represented by other securities shall be the maximum number of
shares of Common Stock which may then be issued upon conversion or exchange
thereof based upon the terms thereof (including any conversion or exchange
rates, as adjusted from time to time in accordance with the terms of such
security).

          (h) Agrees that it and for so long as it holds 5% or more of the
outstanding voting stock of the Company, it shall be present in person or
represented by proxy at all meetings of voting securityholders of the Company
(or to be available to sign consents of securityholders) so that all of the
voting securities then owned by it may be counted for the purpose of determining
the presence of a quorum at any such meeting (or for the purpose of determining
of the requisite percentage of securityholders having signed a consent).

          (i) Agrees that, for so long as the obligations under Section 3(g)(i)
have not expired, it will not in one or more transactions transfer securities
representing more than an aggregate of 800,000 Common Stock Equivalents to (A)
any person which is not an affiliate of the Investor or (B) any group of
persons, each member of which either (x) is affiliated with at least one other
member or (y) would, directly or indirectly, through any contractual
arrangement, understanding or relationship, have or share voting power or
investment power with one or more other members of the group with respect to
such securities, but of which group no member is an affiliate of the Investor,
unless such transferee or transferees agree(s) in writing to be subject to the
terms of Section 3(g) of this Agreement; provided, however, that such condition
                                         --------  -------                     
shall not apply in the case of any transferee which as of the date of this
Agreement is a holder of any shares of Series A, Series B, Series C, Series D or
Series E Convertible Preferred Stock.  The Company agrees that any transferee of
the Investor, that is not described in clause (A) or (B) of the foregoing
sentence, that acquires less than 800,000 Common Stock Equivalents shall not be
bound by Section 3(g)(i).  The Company shall not be obligated to recognize any
transfer made in violation of this Section 3(i).

          (j) Notwithstanding the provisions of paragraph (b) above, no such
registration statement or opinion of counsel shall be necessary for a transfer
by the Investor to any affiliate of the Investor, if the transferee agrees in
writing to be subject to the terms hereof to the same extent as if it were the
original Investor hereunder.

                                      -11-

 
          (k) Notwithstanding the provisions of paragraph (b) above, no such
registration statement or opinion of counsel shall be necessary for a transfer
by the Investor pursuant to Rule 144, if the Investor makes the factual
representations reasonably requested by the Company indicating the availability
of the exemption provided by Rule 144.

     Section 4.  Covenants of the Company.
                 ------------------------ 

          (a) Financial Statements; Inspection.  From and after the date hereof,
              --------------------------------                                  
the Company shall prepare or cause to be prepared, and shall furnish to each
holder of any Securities, the financial statements and related data specified in
Exhibit O, which financial statements and related data shall be acceptable to
each such holder, and shall permit each such holder to inspect at the holder's
expense any of the properties or books and records of the Company and its
subsidiaries, to make copies of extracts from such book and records and to
discuss the affairs and condition of the Company and its subsidiaries with
representatives of the Company and its subsidiaries, all to such reasonable
extent and at such reasonable times and intervals as such holder may reasonably
request.  If the holder is a person or entity other than the Investor, the right
to inspect the properties or books or records of the Company granted under this
paragraph (b) may be exercised only with the consent of the Company, which
consent shall not be unreasonably withheld.  Any holder (including the Investor)
who exercises the right to inspection shall, at the request of the Company, sign
an agreement to hold in confidence any confidential information about the
Company received as a result of such inspection under circumstances indicating
the confidentiality of such information unless (i) such information shall have
been publicly disclosed other than as a result of wrongful action of Investor,
or (ii) Investor independently develops or is aware of such information.

          (b) Intellectual Property.  The Company will use its best efforts to
              ---------------------                                           
keep all intellectual property which is material to the Company's business or
prospects confidential and, to that end, the Company will enter into appropriate
contractual arrangements with each of its employees and such of its consultants,
agents, distributors, licensees, vendors and customers as the Company considers
appropriate.

          (c) Proprietary Interest in Patents, Trademarks, etc.  The Company
              -------------------------------------------------             
will use its best efforts to enter into contractual arrangements with each of
its employees so that the Company shall have sufficient title and ownership of
all patents, trademarks, service marks, trade names, copyrights, trade secrets,
information, proprietary rights and processes as are or may become necessary for
the conduct of its business.

          (d) Right of First Refusal.  Until such time as the Shares shall be
              ----------------------                                         
deemed automatically converted into shares of Common Stock under paragraph
4(d)(ii) of the Certificate, each holder of Series F Preferred, so long as such
holder shall own at least an aggregate 100,000 shares of Series F Preferred or
shares of Common Stock issuable upon conversion of such shares of Series F
Preferred or shares of Common Stock which have been acquired upon the exercise
of the Warrant, as the case may be (a "Preferred Holder"), shall have the right
if the Company shall offer (the "Offer") to sell to any other person or entity
other than a holder of Preferred Stock with a contractual right of first refusal
under, the Series E Agreement, the Series E II Agreement or the Prior
Stockholders Agreement ("Other Purchaser") any voting security of the Company
except 

                                      -12-

 
Permitted Shares as defined in paragraph 4(d)(iii)(A) of the Certificate, or any
securities convertible or exchangeable into or exercisable for voting securities
of the Company, to purchase on the same terms and conditions as such securities
are being offered for sale to the Other Purchasers, up to that number of such
securities that would, after the completion of the sale of all of such
securities (assuming the conversion, exchange or exercise of all securities
which are convertible or exchangeable into or exercisable for voting
securities), result in such Preferred Holder having the same percentage interest
in the voting securities of the Company (based upon the number of votes) as such
holder had prior to such sale. The Company shall provide written notice to each
Preferred Holder of any offer, which notice shall contain the terms and
conditions of the Offer. Each Preferred Holder shall have a period equal to the
longer of (i) 14 days from the date such Preferred Holder receives such notice
from the Company, or (ii) the period of time that Other Purchasers will be
permitted to accept the Offer, to exercise such Preferred Holder's right to
purchase securities under this Section 4(d). Such Preferred Holder shall
exercise the right by providing written notice to the Company of such Preferred
Holder's intent to purchase and the number of shares which such Preferred Holder
intends to purchase. Thereafter, each Preferred Holder shall have a period equal
to the longer of (i) 30 days from the date such Preferred Holder gives notice to
the Company of such Preferred Holder's intent to purchase, or (ii) the period of
time that Other Purchasers are permitted to purchase and pay for securities
pursuant to the Offer, to purchase and pay for the securities pursuant to this
Section 4(d). This right to purchase securities may not be assigned or otherwise
transferred by any Preferred Holder; provided, however, the right of each
                                     --------  -------
Preferred Holder to purchase securities may be apportioned in such a manner as
each Preferred Holder deems appropriate among the affiliates, partners or
retired partners of such Preferred Holder and further provided, however, that
                                              ------- --------  -------
should any Preferred Holder not purchase the full number of securities permitted
under this Section 4(d), each other Preferred Holder shall have the right to
purchase a pro rata portion of such securities.

          (e) Rule 144A Information.  For so Ions as any of the Securities are
              ---------------------                                           
outstanding and are "restricted securities" within the meaning of Rule 144 (a)
(3) under the Act, the Company will provide to any holder of Securities and to
any prospective purchaser of Securities designated by a holder of such
Securities that is a "qualified institutional buyer" (as that term is defined
under Rule 144A), upon the request of such holder or prospective purchaser, the
information and the rights to information required to be provided to such holder
or prospective purchaser by Rule 144A(d)(4).  The Company further agrees that
its obligations pursuant to this paragraph (i) shall extend to any person who
acquires any of the Securities in a transaction pursuant to Rule 144A.

          Section 5.  Drag Along Provision.
                      -------------------- 

          (a) If at any time a written offer meeting the criteria described in
Section 5(b) (the "Offer") is made by a prospective buyer of securities of the
Company for the purchase by such prospective buyer of securities which, together
with Common Stock Equivalents represented by securities then owned by such
prospective buyer, represents two-thirds or more of the outstanding Common Stock
Equivalents (including Common Stock Equivalents represented by securities held
by the Investor) and a copy of such Offer is transmitted to the Investor, then
on and after the 11th day following the transmittal of the Offer to the
Investor, the Offer for the sale of such securities (including securities held
by the Investor) may he accepted by holders who in 

                                      -13-

 
the aggregate, together with the prospective buyer but excluding the Investor,
hold securities representing two-thirds or more of the outstanding Common Stock
Equivalents ("Control Holders"). In such event, the Investor agrees to sell
pursuant to the Offer all the securities owned by the Investor which are subject
to the Offer. The Investor further agrees to execute and deliver such documents
and perform all other actions as shall reasonably be requested by the
prospective buyer and the Control Holders in order to effectuate such sale in
accordance with the terms of the Offer and on a timely basis. Any transferee of
Securities of the Investor (other than an affiliate of the Investor) shall not
be bound by the provisions of this Section 5. This Section 5 shall terminate
upon the earlier of (i) the second anniversary of Company's initial public
offering of securities and (ii) the date on which the Company becomes subject to
the periodic reporting obligations of the Securities Exchange Act of 1934 with
respect to its Common Stock equivalents.

          (b) Any Offer to which Section 5(a) shall apply shall provide that the
Investor (i) shall be paid not less for its Shares than it would have received
under Article 4(b) of the Certificate of Incorporation were the transaction
constituted as a merger and (ii) that the Investor shall be entitled to exercise
the Warrant simultaneously with consummation of the transaction contemplated by
the Offer and to be paid as a holder of Common Stock for such shares.
