           Representations, Warranties and Covenants of the Purchaser

         The Purchaser hereby represents and warrants to and agrees with the
Company, as follows:

         5.1. Accredited Investor; Experience; Risk. The Purchaser is an
accredited investor within the definition of Regulation D of the Securities Act.
The Purchaser has such knowledge and experience in financial and business
matters that it is capable of evaluating the merits and risks of the purchase of
the Convertible Preferred Stock and Warrants.

         5.2. Investment. The Purchaser is acquiring the Convertible Preferred
Stock and Warrants for investment purposes only, for its own account and not as
a nominee or agent for any other Person, and not with a view to, or for resale
in connection with, any distribution thereof in violation of applicable law.

         5.3. Authorization. The Purchaser represents that it has all requisite
power and authority to enter into and perform its obligations under the
Transaction Documents to which it is a party. The execution, delivery and
performance of the Transaction Documents to which Purchaser is a party have been
duly authorized by all necessary action on the part of Purchaser. Each
Transaction Document to which the Purchaser is a party has been duly and validly
executed and delivered by the Purchaser and constitutes the legal, valid and
binding obligation of the Purchaser, enforceable against it in accordance with
its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and similar laws affecting creditors' rights and
remedies generally, and subject, as to enforceability, to general principles of
equity, including principles of commercial reasonableness, good faith and fair
dealing (regardless of whether enforcement is sought in a proceeding at law or
in equity) and except to the extent that rights to indemnification and
contribution under this Agreement may be limited by federal or state securities
laws or public policy relating thereto.

         5.4. Governmental Consents. No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any federal, state, or local governmental authority on the part of
Purchaser is required in connection with the valid execution and delivery by the
Purchaser of the Transaction Documents to which it is a party, or the
consummation by the Purchaser of the transactions contemplated by the
Transaction Documents to which it is a party, except for such filings as have
been made prior to the Closing.

         5.5. Brokers' Fees. No broker, finder, investment banker or other
Person is entitled to any brokerage fee, finder's fee or other commission in
connection with the transactions contemplated by this Agreement based upon
arrangements made by the Purchaser.

         5.6. Unregistered Shares. The Purchaser understands and acknowledges
that none of the Convertible Preferred Stock, the shares of Common Stock
issuable upon conversion of the Convertible Preferred Stock, the Warrants or the
shares of Common Stock issuable upon exercise


                                     - 22 -
<PAGE>   27
of the Warrants have been registered under the Securities Act or any state
securities laws and are therefore "unregistered securities" as that term is used
in the Securities Act, and as such may not be offered for sale, sold or
otherwise disposed of without such registration or an opinion of counsel
reasonably satisfactory to the Company that such sale or disposition can be made
pursuant to an exemption from registration under the Securities Act and any
applicable state securities laws. Purchaser agrees a legend that reflects the
foregoing shall be placed on any certificates evidencing the securities
purchased herein and that, so long as the legend may remain on such
certificates, that the Company may maintain appropriate "stop transfer" orders
with respect to such securities on its books and records and with those to whom
it may delegate registrar and transfer functions. Purchaser further agrees and
acknowledges that, except as set forth in Section 8.3 of this Agreement, the
Company does not have any obligation or other commitment to register any of the
securities issued or to be issued pursuant to this Agreement.

         5.7. Access to Information. The Purchaser acknowledges receipt of the
Company's Annual Report on Form 10-K for the fiscal year ended December 31, 1996
and Quarterly Report on Form 10-Q for the fiscal period ended June 30, 1997. The
Purchaser further represents and acknowledges that it has carefully read such
reports and has been furnished by the Company during the course of this
transaction with all additional information regarding the Company that it has
requested; that Purchaser has been afforded the opportunity to ask questions of
and receive answers from duly authorized officers or other representatives of
the Company concerning the Company and the terms and conditions of this
transaction and has utilized such opportunity to Purchaser's satisfaction.

         5.8 Restricted Transfer of Securities. The Purchaser agrees that, for a
period of two (2) years commencing on the date of this Agreement (the
"Restricted Period"), the securities issued or to be issued pursuant to this
Agreement, including without limitation the Registrable Securities
(collectively, the "Issued Securities"), may not be sold, assigned or otherwise
transferred to a Restricted Person without the prior written consent of the
Company. For purposes of this Section 5.8, "Restricted Person" means any Person
engaged in or intending to be engaged in, either directly or indirectly
(including, without limitation, through an Affiliate or in concert with another
Person), any business in which the Company is operating on the date of the
proposed sale, assignment or transfer. Following the Restricted Period, the
Issued Securities may be sold, assigned or otherwise transferred without
limitation if the average closing price for the Common Stock quoted on the
Nasdaq National Market System (or on any exchange on which the Common Stock is
then listed) for the thirty (30) trading days immediately prior to the last day
of the Restricted Period (the "Benchmark Price") is equal to or less than $12.00
per share. If the Benchmark Price is greater than $12.00 per share, then the
restrictions on the Issued Securities set forth in the first sentence of this
Section 5.8 shall continue after the Restricted Period. Notwithstanding anything
contained in this Section to the contrary, the Purchaser may assign any or all
of the Issued Securities to partners or Affiliates of the Purchaser or officers
or directors of partners or Affiliates of the Purchaser without consent of the
Company so long as such partner, Affiliate, officer or director agrees in
writing to be bound by the terms of this Agreement.

year, a consolidated and consolidating budget for the following fiscal year.

                  (d) Other Reports and Statements. Promptly upon any
distribution to its stockholders generally, to its directors or to the financial
community of an annual report, quarterly report, proxy statement, registration
statement or other similar report or communication, a copy of each such annual
report, quarterly report, proxy statement, registration statement or other
similar report or communication and promptly upon filing by the Company with the
SEC or with The National Market System, Inc., the National Association of
Securities Dealers, Inc. or any national securities exchange or other market
system of any all regular and other reports or applications, a copy of each such
report or application; and a copy of such report or statement and copies of all
press releases and other statements made available generally by the Company to
the public concerning material developments in the Company.

         8.2      Preemptive Rights.

                  (a) If, after the Closing Date but prior to the conversion of
the Convertible Preferred Stock into Common Stock the Company shall propose to
issue or sell New Securities or enters into any contracts, commitments,
agreements, understandings or arrangements of any kind relating to the issuance
or sale of any New Securities, the Purchaser shall have the right to purchase
that number of New Securities at the same price and on the same terms proposed
to be issued or sold by the Company so that the Purchaser would after the
issuance and sale of all such New Securities, hold the same proportionate
interest (the "Proportionate Percentage") of the then outstanding shares of
Common Stock as was held by the Purchaser immediately prior to such issuance and
sale (based upon the number of shares of Common Stock to be received upon
conversion of the Convertible Preferred Stock and exercise of the Class II
Warrants).


                                     - 26 -
<PAGE>   31
                  (b) The Company shall give the Purchaser written notice of its
intention to issue and sell New Securities, describing the type of New
Securities, the price and the general terms and conditions upon which the
Company proposes to issue the same. The Purchaser shall have fifteen (15) days
(the "Offer Period") from the giving of such notice to agree to purchase all (or
any part) of its Proportionate Percentage of New Securities for the price and
upon the terms and conditions specified in the notice by giving written notice
to the Company and stating therein the quantity of New Securities to be
purchased.

                  (c) If the Purchaser fails to provide notice to the effect
that Purchaser agrees to exercise in full such right within the Offer Period,
the Company shall have 125 days thereafter to sell the New Securities in respect
of which the Purchaser's rights were not exercised, at a price and upon general
terms and conditions no more favorable to the buyers thereof than specified in
the Company's notice to Purchaser pursuant to this Section. If the Company has
not sold the New Securities within such 125-day period, the Company shall not
thereafter issue or sell any New Securities, except by giving the Purchaser the
right to purchase its Proportionate Percentage in the manner provided above.

         8.3      Company Registration.

                  (a) If the Company proposes to register any of its securities
either for its own account or the account of a security holder or holders
exercising their respective demand registration rights, other than a
registration relating solely to employee benefit plans, or a registration
relating to a corporate reorganization or other transaction under Rule 145, or a
registration on any registration form that does not permit secondary sales, the
Company will (i) promptly give to the Purchaser and to each Holder written
notice thereof, and (ii) use its best efforts to include in such registration
(and any related qualification under blue sky laws or other compliance), except
as set forth in Section 8.3(b) below, and in any underwriting involved therein,
all the Registrable Securities specified in a written request or requests, made
by the Purchaser and any Holder and received by the Company within fifteen (15)
days after the written notice from the Company described in clause (i) above is
delivered by the Company.

                  (b) If the registration as to which the Company gives notice
is for a registered public offering involving an underwriting, the Company shall
so advise the Purchaser and the Holders as a part of the written notice given
pursuant to Section 8.3(a). In such event, the right of the Purchaser and any
Holder to registration pursuant to this Section 8.3 shall be conditioned upon
such participation in such underwriting and the inclusion of the Purchaser's and
the Holder's Registrable Securities in the underwriting to the extent provided
herein. The Purchaser and all Holders proposing to distribute their securities
through such underwriting shall (together with the Company and the other holders
of securities of the Company with registration rights to participate therein
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the representative of the
underwriter or underwriters selected by the Company.


                                     - 27 -
<PAGE>   32
         Notwithstanding any other provision of this Section 8.3, if the
underwriters advise the Company in writing that marketing factors require a
limitation on the number of shares to be underwritten, the underwriters may
(subject to the limitations set forth below) exclude all Registrable Securities
from, or limit the number of Registrable Securities to be included in, the
registration and underwriting. The Company shall so advise all holders of
securities requesting registration, and the number of shares of securities that
are entitled to be included in the registration and underwriting shall be
allocated first to the Company and to the Purchaser and thereafter to all other
holders of securities requesting registration. If any person does not agree to
the terms of any such underwriting, he shall be excluded therefrom by written
notice from the Company or the underwriter. Any Registrable Securities or other
securities excluded or withdrawn from such underwriting shall be withdrawn from
such registration.

         8.4.     Shelf Registration.

                  (a) As soon as practicable after Closing, the Company shall
prepare and file with the SEC a registration statement for an offering to be
made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act
(a "Shelf Registration") registering the resale from time to time by the
Purchaser and each Holder of all of the Registrable Securities issuable upon
conversion of the Convertible Preferred Stock (the "Initial Shelf
Registration"). The registration statement for any Shelf Registration shall be
on Form S-3 or another appropriate form permitting registration of such
Registrable Securities for resale by the Purchaser and each Holder in the manner
or manners designated by them, from time to time, which may include an
underwritten offering, subject to the underwriter being reasonably acceptable to
the Company and the Purchaser. The Company shall use its best efforts to cause
the Initial Shelf Registration to become effective under the Securities Act as
promptly as is practicable and to keep the Initial Shelf Registration
continuously effective under the Securities Act until the end of the
Effectiveness Period.

                  (b) From and after the exercise of any Warrant, in whole or in
part, within 45 days after receipt of written notice from the Purchaser or
Holder, the Company shall effect a Shelf Registration for all or a portion of
the Warrant shares which have been theretofore issued to Purchaser or Holder;
provided, however, that (A) the number of Warrant shares sought to be included
in any Shelf Registration shall not be less than 50% of the shares of Common
Stock or other securities for which the Warrant is exercisable and (B) in no
event shall the Company be obligated to effect a Shelf Registration pursuant to
this paragraph on more than one occasion in any 12-month period.

                  (c) If the Initial Shelf Registration or any Subsequent Shelf
Registration (as defined below) ceases to be effective for any reason at any
time during the Effectiveness Period (other than because all Registrable
Securities shall have been sold or shall have ceased to be Registrable
Securities), the Company shall use its best efforts to obtain the prompt
withdrawal of any order suspending the effectiveness thereof, and in any event
shall within thirty (30) days of such cessation of effectiveness amend the Shelf
Registration in a manner reasonably expected to obtain the withdrawal of the
order suspending the effectiveness thereof, or file an additional Shelf
Registration covering all of the Registrable Securities then outstanding (a
"Subsequent Shelf


                                     - 28 -
<PAGE>   33
Registration"). If a Subsequent Shelf Registration is filed, the Company shall
use all reasonable efforts to cause the Subsequent Shelf Registration to become
effective as promptly as is practicable after such filing and to keep such
registration statement continuously effective until the end of the Effectiveness
Period.

                  (d) The Company shall supplement and amend the Shelf
Registration if required by the rules, regulations or instructions applicable to
the registration form used by the Company for such Shelf Registration, if
required by the Securities Act or the SEC, or if reasonably requested by the
Purchaser or a majority of Holders or by any managing underwriter, if any, of
such Registrable Securities with respect to the offer and sale or other
disposition of the Registrable Securities during the Effective Period.

                  (e) From time to time, the Company shall (i) prepare and file
with the SEC a post-effective amendment to the Shelf Registration or a
supplement to the related prospectus or a supplement or amendment to any
document incorporated therein by reference or any other required document, so
that such registration statement will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, so that, as thereafter
delivered to purchasers of the Registrable Securities being sold thereunder,
such prospectus will not contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading; (ii) provide the Purchaser and the Holders with copies of any
registration statement, prospectus, document incorporated by reference therein,
or such other documents filed with the SEC in such numbers as the Purchaser and
the Holders shall reasonably request; and (iii) inform the Purchaser and the
Holders that the Company has complied with its obligations and that the
registration statement and related prospectus may be used for the purpose of
selling all or any of such Registrable Securities (or that, if the Company has
filed a post-effective amendment to the Shelf Registration which has not yet
been declared effective, the Company will notify Purchaser to that effect, will
use its best efforts to secure the effectiveness of such post-effective
amendment and will immediately so notify Purchaser when the amendment has become
effective).

         8.5 Certain Securities Registration Matters. Whenever the Company is
required under Section 8.3 or 8.4 to effect the registration with the SEC of any
Registrable Securities, the following provisions shall apply:

                  (a) The Company shall cause the Registrable Securities covered
by such registration statement to be registered with or approved by such other
governmental agencies or authorities as may be necessary by virtue of the
business and operations of the Company to enable Purchaser or Holder to
consummate the disposition of such Registrable Securities.

                  (b) The Company shall cause all Registrable Securities covered
by any registration statement to be listed with the Nasdaq Stock Market, or on
each securities exchange on which similar securities issued by the Company are
then listed and, unless the same already exists, provide a transfer agent,
registrar and CUSIP number for all such Registrable Securities not later


                                     - 29 -
<PAGE>   34
than the effective date of the registration statement.

                  (c) The Company shall enter into such customary agreements
(including an underwriting agreement in customary form, if applicable) and take
all such other actions as the Purchaser or Holder or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities pursuant to the registration statement.

                  (d) The Company shall make available for inspection by the
Purchaser, Holder and any underwriter participating in any disposition pursuant
to such registration statement, and any attorney, accountant or other agent
retained by the Purchaser, Holder or underwriter (collectively, the
"Inspectors"), all financial and other records, pertinent corporate documents
and agreements and access to properties and management and other information of
the Company as shall be necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all information reasonably requested by any Inspector in connection with
such registration statement, provided that any Inspector shall have first
executed and delivered to the Company a confidentiality agreement in customary
form protecting the confidentiality of such information, except as otherwise
required to be disclosed by law.

                  (e) If the Registrable Securities are to be sold in an
underwritten offering or in a private transaction involving the sale or transfer
of at least forty percent (40%) of the Registrable Securities issuable upon
conversion of the Convertible Preferred Stock acquired pursuant to this
Agreement, the Company shall obtain "cold comfort" letters and updates thereof
from the Company's independent public accountants and an opinion from the
Company's counsel in customary form and covering such matters of the type
customarily covered by "cold comfort" letters and opinion letters as the
managing underwriter or Purchaser, as the case may be, may reasonably request,
and one copy of such "cold comfort" letter and opinion letter shall be provided
to each of the Purchaser and the Holder.

                  (f) The Purchaser and Holders shall, upon receipt of any
notice from the Company of the happening of any event of the kind described in
Section 8.5(i), discontinue disposition of its Registrable Securities pursuant
to the registration statement covering such Registrable Securities until receipt
of the copies of the supplemented or amended prospectus and, if so directed by
the Company, the Purchaser and Holders will deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in the
Purchaser's and Holders' possession, of the prospectus covering such Registrable
Securities current at the time of receipt of such notice.

                  (g) All fees and expenses incident to the Company's
performance of or compliance with a registration statement requirement pursuant
to this Agreement shall be borne by the Company whether or not any of the
registration statements become effective, other than commissions and
underwriter's discounts, if any, and transfer taxes payable by Purchaser and/or
the Holder. Such fees and expenses shall include, without limitation, (i) all
registration and filing fees (including, without limitation, fees and expenses
(x) with respect to filings required to be made with the National Association of
Securities Dealers, Inc. and (y) of compliance with federal securities or


                                     - 30 -
<PAGE>   35
Blue Sky laws (including, without limitation, fees and disbursements of one
counsel to Purchaser in connection with Blue Sky qualifications of the
Registrable Securities under the laws of such jurisdictions as the managing
underwriter, if any, or the Purchaser may designate)), (ii) printing expenses,
(iii) messenger, telephone and delivery expenses, (iv) reasonable fees and
disbursements of counsel for the Company and one counsel for the Purchaser in
connection with the registration, (v) fees and disbursements of all independent
certified public accountants (including the expenses of any special audit and
"comfort" letters required by or incident to such performance) and (vi)
Securities Act liability insurance obtained by the Company in its sole
discretion. In addition, the Company shall pay its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange or the Nasdaq Stock Market, as the case
may be, on which similar securities issued by the Company are then listed and
the fees and expenses of any Person, including special experts, retained by the
Company. Notwithstanding the provisions of this subsection, the Purchaser or the
Holders, as the case may be, shall pay all registration expenses to the extent
the Company is prohibited by applicable Blue Sky laws from paying for or on
their behalf.

                  (h) The Company shall use its reasonable best efforts to
register or qualify the Registrable Securities under such securities or Blue Sky
laws in such jurisdictions as the Purchaser or the Holders may reasonably
request; provided that the Company shall not be required in connection therewith
or as a condition thereof to (i) qualify or register as a foreign corporation in
any such jurisdiction, (ii) execute a general or limited consent to service of
process in any such jurisdiction, (iii) make any undertaking with respect to the
conduct of its business, (iv) subject itself to taxation as a foreign
corporation in any such jurisdiction or (v) enter into any agreement with any
state securities or "blue sky" commission or agency, including, without
limitation, any agreement to escrow shares of its capital stock.

                  (i) If, in the reasonable judgment of the Company, it is
advisable to suspend use of the prospectus for a period of time due to pending
material corporate developments or similar material events that have not yet
been publicly disclosed and as to which the Company believes public disclosure
will be prejudicial to the Company, the Company shall deliver a certificate in
writing, signed by its Chief Executive Officer, Chief Financial Officer or
General Counsel, to the Purchaser and Holders and the managing underwriter, if
any, to the effect of the foregoing and, upon receipt of such certificate, the
Purchaser's and Holders' selling period will not commence until the Purchaser,
Holders or managing underwriter, if any, has received copies of the supplemented
or amended Prospectus, or until it is or they are advised in writing by the
Company that the Prospectus may be used, and has received copies of any
additional or supplemental filings that are incorporated or deemed incorporated
by reference in such Prospectus. The Company will use all reasonable efforts to
ensure that the use of the Prospectus may be resumed, and the selling period may
commence, upon the earlier of (x) public disclosure of such pending material
corporate development or similar material event or (y) a determination by the
Company that, in the judgment of the Company, public disclosure of such material
corporate development or similar material event would not be prejudicial to the
Company. Notwithstanding the foregoing, the Company shall not under any
circumstances be entitled to exercise its right under this Section 8.5(i) to
defer the selling period


                                     - 31 -
<PAGE>   36
more than one time in any 12-month period or two times in any 24-month period;
and provided, further, that the period in which a selling period is suspended
shall not exceed ninety (90) days.

                  (j) In the event of the registration or qualification of any
Registrable Securities with the SEC pursuant to a registration statement, the
Company agrees to indemnify and hold harmless Purchaser, Holders and each
officer, partner, employee, agent and representative of Purchaser and Holders,
each underwriter, broker or dealer, if any, of such Registrable Securities, and
each other Person, if any, who controls Purchaser and Holder, underwriter,
broker or dealer within the meaning of the Securities Act, Exchange Act or any
other applicable securities laws, from and against any and all losses, claims,
damages or liabilities (or actions in respect thereof) (collectively, the
"Losses") joint or several, to which any of them may become subject under the
Securities Act or any other applicable securities laws or otherwise, insofar as
such Losses arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Registrable Securities were registered or qualified under the
Securities Act or any other applicable securities laws, any preliminary
prospectus or final prospectus relating to such Registrable Securities, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, or any
violation by the Company of any rule or regulation under the Securities Act or
any other applicable securities laws applicable to the Company or relating to
any action or inaction required by the Company in connection with any such
registration or qualification and will reimburse Purchasers, each officer,
director, employee, agent and representative of Purchaser, Holders, underwriter,
broker or dealer and each such controlling Person for any legal or other
expenses reasonably incurred by any of them in connection with investigating or
defending any such Loss; provided, however, that the Company will not be liable
in any such case to the extent that any such Loss arises out of or is based upon
untrue statement of a material fact or omission to state a material fact
necessary to make the statements, in light of the circumstances under which they
were made in such registration statement, such preliminary prospectus, such
final prospectus or such amendment or supplement thereto, not misleading, in
reliance upon and in conformity with written information furnished to the
Company by Purchaser, Holders, or any officer, partner, employee, agent and
representative thereof specifically and expressly for use in the preparation
thereof,or any violation of any rule or regulation under the Securities Act or
applicable securities laws, in which case such person agrees to indemnify and
hold harmless the Company and its Affiliates from and against any and all
Losses, joint or several, to which any of them may become subject under the
Securities Act or any other applicable securities laws or otherwise; and
provided, further, that the Company shall not be liable to any Person who
participates as an underwriter in the offering or sale of Registrable Securities
or any other Person, if any, who controls such underwriter within the meaning of
the Securities Act, in any such case to the extent that any such Loss (or action
or proceeding in respect thereof) or expense arises out of such Person's failure
to send or give a copy of the Prospectus, as the same may be then supplemented
or amended, to the Person asserting an untrue statement or alleged untrue
statement or omission or alleged omission at or prior to the written
confirmation of the sale of Registrable Securities to such Person if such
statement or omission was corrected in such Prospectus so long as such
Prospectus, and any amendments or supplements thereto, have been furnished to
such underwriter in sufficient numbers and in a timely-manner to permit
distribution thereof.


                                     - 32 -
<PAGE>   37
                                                                       
                                                                             
                  Promptly after receipt by a Person entitled to indemnification
under this Section 8.5(j) (an "Indemnified Party") of notice of the commencement
of any action or claim relating to any registration statement as to which
indemnity may be sought hereunder, such Indemnified Party will, if a claim for
indemnification hereunder in respect thereof is to be made against any other
party hereto (an "Indemnifying Party"), give written notice to such Indemnifying
Party of the commencement of such action or claim, but the omission to so notify
the Indemnifying Party will not relieve the Indemnifying Party from any
liability that it may have to any Indemnified Party except to the extent that
the Indemnifying Party is actually prejudiced thereby. In case any such action
is brought against an Indemnified Party, and it notifies an Indemnifying Party
of the commencement thereof, the Indemnifying Party will be entitled (at its own
expense) to participate in and, to the extent that it may wish, jointly with any
other indemnifying party similarly notified, to assume the defense, with counsel
reasonably satisfactory to such Indemnified Party, of such action provided that
the Indemnifying Party shall not settle or compromise such action, except upon
the prior written consent of the Indemnified Party and, after notice from the
Indemnifying Party to such Indemnified Party of its election so to assume the
defense thereof, the Indemnifying Party will not be liable to such Indemnified
Party for any legal or other expenses subsequently incurred by such Indemnified
Party in connection with the defense thereof, other than the reasonable cost of
investigation; provided, however, that the assumption of such defense shall not
give rise in the reasonable opinion of the Indemnified Party or its counsel to
any conflict. Notwithstanding the foregoing, the Indemnified Party shall have
the right to employ its own counsel in any such case, but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party unless (A) the
employment of such counsel shall have been authorized in writing by the
Indemnifying Party in connection with the defense of such suit, action, claim or
proceeding, (B) the Indemnifying Party shall not have employed counsel
(reasonably satisfactory to the Indemnified Party) to take charge of the defense
of such action, suit, claim or proceeding, or (C) such Indemnified Party shall
have reasonably concluded, based upon the advice of counsel, that there may be
defenses available to it that are different from or additional to those
available to the Indemnifying Party which, if the Indemnifying Party and the
Indemnified Party were to be represented by the same counsel, could result in a
conflict of interest for such counsel or materially prejudice the prosecution of
the defenses available to such Indemnified Party. If any of the events specified
in clauses (A), (B) or (C) of the preceding sentence shall have occurred or
shall otherwise be applicable, then the reasonable fees and expenses of one
counsel or firm of counsel selected by the Indemnified Party (and reasonably
acceptable to the Indemnifying Party) shall be borne by the Indemnifying Party.
If, in any such case, the Indemnified Party employs separate counsel, the
Indemnifying Party shall not have the right to direct the defense of such
action, suit, claim or proceeding on behalf of the Indemnified Party and the
Indemnified Party shall assume such defense and/or settle or compromise such
action; provided, however, that an Indemnifying Party shall not be liable for
the settlement or compromise of any action, suit, claim or proceeding effected
without its prior written consent, which consent shall not be unreasonably
withheld.

                           (iii) Notwithstanding the foregoing, to the extent
that the provisions on indemnification and contribution contained in the
underwriting agreement entered into in connection with any underwritten public
offering contemplated by this Agreement are in conflict with the foregoing
provisions, the provisions in such underwriting agreement shall be controlling.


                                     - 33 -
<PAGE>   38
                  (k) The Purchaser and each Holder holding securities included
in any registration shall furnish to the Company such information regarding the
Purchaser or such Holder and the distribution proposed by the Purchaser or such
Holder as the Company may reasonably request in writing and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to in this Section 8.

                  (l) The Company shall not, directly or indirectly, enter into
any merger, consolidation, or reorganization in which the Company shall not be
the surviving corporation unless the proposed surviving corporation shall, prior
to such merger, consolidation, or reorganization, agree in writing to assume the
obligations of the Company under this Section, and for that purpose references
hereunder to "Registrable Securities" shall be deemed to be references to the
securities that the Purchaser or Holders, as the case may be, would be entitled
to receive in exchange for Registrable Securities under any such merger,
consolidation, or reorganization; provided, however, that the provisions of this
Section shall not apply in the event of any merger, consolidation, or
reorganization in which the Company is not the surviving corporation if the
Purchaser and Holders are entitled to receive in exchange for their Registrable
Securities consideration consisting solely of (i) cash, (ii) securities of the
acquiring corporation that may be immediately sold to the public without
registration under the Securities Act, or (iii) securities of the acquiring
corporation that the acquiring corporation has agreed to register within 90 days
of completion of the transaction for resale to the public pursuant to the
Securities Act.

         8.6 Regulatory Matters. Each of the Company and Purchaser will (i) make
on a prompt and timely basis all governmental or regulatory notifications,
filings or submissions, as necessary for the consummation of the transactions
contemplated hereby, including any filings required pursuant to the
Hart-Scott-Rodino Antitrust Act, if required, (ii) use all reasonable efforts to
cooperate with the other and its representatives in (A) determining which
notifications, filings and submissions are required to be made prior to the
Closing Date with, and which consents, approvals, permits or authorizations are
required to he obtained prior to the Closing Date from, any governmental
authority in connection with the execution, delivery and performance of this
Agreement and the transactions contemplated hereby, and (B) timely making of all
such notifications, filings or submissions and timely seeking all such consents,
approvals, permits or authorizations, and (iii) use all reasonable efforts to
take, or cause to be taken, all other action and do, or cause to be done, all
other reasonable things necessary or appropriate to consummate the transactions
contemplated by this Agreement. The Purchaser shall have no obligation to expend
any funds in connection with the action to be taken by the Company pursuant to
this section.

         8.7 Access. So long as the Purchaser holds at least fifteen percent
(15%) of the Convertible Preferred Stock purchased hereunder, subject to the
provisions of Section 8.8 hereof, upon the written request of the Purchaser, the
Company shall afford the Purchaser and its accountants, counsel and other
representatives, full access during normal business hours to all of its
properties, books, contracts, commitments and records, permit them to copy or
make extracts therefrom and, the Company shall furnish promptly to Purchaser all
information concerning its business, properties and personnel as Purchaser may
reasonably request; provided, however, that no investigation pursuant to this
Section 8.7 shall affect any representations or warranties of either


                                     - 34 -
<PAGE>   39
party hereunder.

         8.8 Confidentiality. From and after the date of this Agreement, each of
the Company and Purchaser agree to hold, and will cause its employees, agents
and representatives to hold, in confidence, unless compelled to disclose by
judicial or administrative process or, in the written opinion of their counsel,
by other requirements of law, information furnished by the Company, on the one
hand, to Purchaser and information furnished by Purchaser, on the other hand, to
the Company in connection with the transactions contemplated by this Agreement,

(each, an "Indemnified Party"), from and against any and all actual losses,
claims, damages, liabilities, costs and expenses (including, without limitation,
liabilities, costs and expenses and all reasonable fees, expenses and
disbursements of counsel), joint or several (hereinafter collectively referred
to as a "Loss"), which may be incurred by or asserted or awarded against any
Indemnified Party in connection with or in any manner arising out of or relating
to any investigation, litigation or proceeding or the preparation of any defense
with respect thereto, arising out of or in connection with or relating to the
transactions contemplated by this Agreement and the other Transaction Documents,
except to the extent such Loss is found in a final


                                     - 38 -
<PAGE>   43
judgment by a court of competent jurisdiction to have resulted from such
Indemnified Party's gross negligence or willful misconduct.

                    (b) An Indemnified Party shall give written notice to the
Company of any claim with respect to which it seeks indemnification within ten
(10) days after the discovery by such parties of any matters giving arise to a
claim for indemnification pursuant to Section 9.11(a); provided that the failure
of any Indemnified Party to give notice as provided herein shall not relieve the
Company of its obligations under this Section 9.11, except to the extent that
the Company is actually prejudiced by such failure to give notice. In case any
such action or claim is brought against any Indemnified Party, the Company shall
be entitled to participate in and, unless in the reasonable good faith judgment
of the Indemnified Party a conflict of interest between such Indemnified Party
and the Company may exist in respect of such action or claim, to assume the
defense thereof, with counsel reasonably satisfactory to the Indemnified Party
and, after notice from the Company to the Indemnified Party of its election so
to assume the defense thereof, the Company shall not be liable to such
Indemnified Party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof other than reasonable costs of
investigation. In any event, unless and until the Company elects in writing to
assume and does so assume the defense of any such action or claim the
Indemnified Party's reasonable costs and expenses arising out of the defense,
settlement or compromise of any such action or claim shall be Losses subject to
indemnification hereunder. If the Company elects to defend any such action or
claim, then the Indemnified Party shall be entitled to participate in such
defense with counsel of its choice at its sole cost and expense. The Company
shall not be liable for any settlement of any action or claim effected without
its written consent. Anything in this Section 9.11 to the contrary
notwithstanding, the Company shall not, without the Indemnified Party's prior
written consent, settle or compromise any claim or consent to entry of any
judgment in respect thereof that imposes any future obligation on the
Indemnified Party or that does not include, as an unconditional term thereof,
the giving by the claimant or the plaintiff to the Indemnified Party, a release
from all liability in respect of such claim.
