                                   SECTION IV

                REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

     Each Purchaser, severally and not jointly, hereby represents and warrants,
on the date hereof and as of the closing date applicable to such Purchaser, to
the Company with respect to the purchase of the Shares and the Warrants as
follows:

     4.1. Experience. It has substantial experience in evaluating and
investigating private placement transactions of securities in companies similar
to the Company so that it is capable of evaluating the merits and risks of its
investment in the Company and has the capacity to protect its own interests.

     4.2. Investment. It is acquiring the Shares, the Warrants, and the Warrant
Stock for investment for its own account, not as a nominee or agent, and not
with the view to, or for resale in connection with, any distribution thereof. It
understands that the Shares, the Warrants, and the Warrant Stock have not been,
and will not be, registered under the Securities Act by reason of a specific
exemption from the registration provisions of the Securities Act, the
availability of which depends upon, among other things, the bona fide nature of
the investment intent and the accuracy of the Purchaser's representations as
expressed herein.

     4.3. Rule 144. It acknowledges that the Shares, the Warrants, and the
Warrant Stock must be held indefinitely unless (a) subsequently registered under
the Securities Act, (b) an


                                     - 12 -
<PAGE>   13


exemption from such registration is available, or (c) sold or transferred
pursuant to Rule 144 promulgated under the Securities Act ("Rule 144"). It is
aware of the provisions of Rule 144 which permit limited resale of shares
purchased in a private placement subject to the satisfaction of certain
conditions, including, among other things, the existence of a public market for
the shares, the availability of certain current public information about the
Company, the resale occurring not less than one year after a party has purchased
and paid for the security to be sold, the sale being effected through a
"broker's transaction" or in transactions directly with a "market maker," the
number of shares being sold during any three-month period not exceeding
specified limitations and the filing of a Form 144 with the Securities and
Exchange Commission.

     4.4. Access to Data. It has had an opportunity to discuss the Company's
business, management and financial affairs with the Company's management and has
had the opportunity to review the Company's facilities. It has also had an
opportunity to ask questions of officers of the Company, which questions were
answered to its satisfaction. It understands that such discussions, as well as
any written information issued by the Company, were intended to describe certain
aspects of the Company's business and prospects but were not a thorough or
exhaustive description.

     4.5. Authorization. This Agreement when executed and delivered by the
Purchaser will constitute a valid and binding obligation of the Purchaser,
enforceable against the Purchaser in accordance with its terms. All corporate
action on the part of the Purchaser, its directors and shareholders necessary
for the authorization, execution, delivery and performance of this Agreement by
the Purchaser, and the performance of all of the Purchaser's obligations
hereunder has been taken or will be taken prior to the Closing.

     4.6. Brokers or Finders. The Company will not incur, directly or
indirectly, as a result of any action taken by the Purchaser, any liability for
brokerage or finders' fees or agents' commissions or any similar charges in
connection with this Agreement.

     4.7. Accredited Investor. Purchaser is an "accredited investor" as such
term is defined in the Securities Act of 1933, as amended.

     4.8. SEC Filings. The Purchaser has reviewed all public filings of the
Company that have been filed with the Securities and Exchange Commission by the
Company within the past year.

     7.1. Definitions. As used in this Section VII:

             (a) the terms "register", "registered" and "registration" refer to

     or required to be filed) and the declaration or ordering of effectiveness
     of such registration statement;

             (b) the term "Registrable Securities" means (i) shares of Common

     issuable and (ii) any capital stock of the Company issued as a dividend or
     other distribution with respect to, or in exchange for or in replacement
     of, the shares referred to in clause (i) above;

             (c) the term, "Holder" shall mean any holder of Registrable
     Securities;

             (d) "SEC" shall mean the Securities and Exchange Commission or any
     other federal agency at the time administering the Securities Act;

             (e) "Registration Expenses" shall mean all expenses incurred by the

     indicates otherwise, the resale registration statement on Form S-1 filed by
     the Company pursuant to Rule 415 under the Securities Act covering the

<PAGE>   17

     or the resale registration statement on Form S-3 filed by the Company in

     and

             (g) "Securities" shall have the meaning set forth in Section 2(l)
     of the Securities Act.

     7.2. Resale Registration on Form S-1. Within sixty days after the Closing

     Registration Statement becomes effective, (y) when any amendment to such
     Registration Statement becomes effective and (z) of any request by the SEC
     for any amendment or supplement to such Registration Statement or any
     prospectus relating thereto or for additional information.

             (ii) promptly prepare and file with the SEC such amendments and
     supplements to such Registration Statement and the prospectus used in
     connection therewith as may be necessary to keep such Registration
     Statement effective.


                                     - 17 -
<PAGE>   18


             (iii) furnish to the Holders copies of the Registration Statement
     as filed and thereafter, such number of copies of the Registration
     Statement, each amendment and supplement thereto, the prospectus included
     in such registration statement (including each preliminary prospectus),
     reports on Form 10-K, 10-Q and 8-K (or their equivalents) which the Company
     shall have filed with the SEC and financial statements, reports and proxy
     statements mailed to shareholders of the Company as the Holders may
     reasonably request in order to facilitate the disposition of the
     Registrable Securities being offered by the Holders;

             (iv) use its best efforts to register or qualify, not later than
     the effective date of any filed Registration Statement, the Registrable
     Securities covered by the Registration Statement under the securities or
     "blue sky" laws of such jurisdictions as the Holder may reasonably request;

             (v) during the period when the registration statement is required
     to be effective, notify the Holders of the happening of any event as a
     result of which the prospectus included in the Registration Statement
     contains an untrue statement of a material fact or omits to state any
     material fact required to be stated therein or necessary to make the
     statement therein not misleading, and the Company will forthwith prepare a
     supplement or amendment to such prospectus so that, as thereafter delivered
     to the purchasers of such Registrable Securities, such prospectus will not
     contain an 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;

             (vi) cause such Registrable Securities to be traded on each
     securities exchange or automated interdealer quotation system on which
     similar Securities issued by the Company are then traded, provided that the
     Company is eligible to do so under applicable listing requirements; and

             (vii) otherwise use its best efforts to comply with all applicable
     rules and regulations of the SEC, and make available to the holders of the
     Company's Securities, as soon as reasonably practicable, an earnings
     statement governing a period of 12 months, beginning after the effective
     date of the Registration Statement, which earnings statement shall satisfy
     the provisions of Section 11(a) of the Act.

     (b) The Holder shall timely furnish to the Company any such information
regarding the distribution of such Registrable Securities as the Company may
from time to time reasonably request.

     (c) Each of the Holders agree that upon the receipt of any notice from the
Company of the happening of any event of the kind described in paragraph
(a)(viii) above, it will forthwith discontinue disposition of Registrable
Securities pursuant to the Registration Statement until



                                     - 18 -
<PAGE>   19


receipt by the Holders of the copies of the supplemented or amended prospectus
contemplated by paragraph (a)(viii) above.

     7.5. Piggy-back Registration.

     (a) If the Company shall determine to register any of its Securities in
connection with an underwritten public offering by the Company, then the Company
will:

             (i) promptly give to each of the Holders a written notice thereof;
     and

             (ii) include in such registration (and any related qualification
     under blue sky laws or other compliance), and in the underwriting involved
     therein, all the Registrable Securities specified in a written request or
     requests, made by the Holders within 20 business days after receipt of the
     written notice from the Company described in clause (i) above, except as
     the number of such Registrable Securities may be limited by Section 7.5(b)
     below. Such written request may specify all or a part of the Holders'
     Registrable Securities.

     (b) Underwriting. In the event the Company provides the notice described in
Section 7.5(a)(i), the right of each of the Holders to registration pursuant to
this Section 7.5 shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided therein. The Holders shall and it shall be a
condition of their participation in any such registration and underwriting that
any other shareholders distributing Securities through such underwriting also
enter into an underwriting agreement in customary form (including, without
limitation, such indemnity and contribution provisions as the underwriter or
underwriters customarily require) with the underwriter or underwriters selected
by the Company. Notwithstanding any other provision of this Section 7.5, if the
managing underwriter or representative of the managing underwriter advises the
Company in writing that marketing factors require a limitation on the number of
shares to be underwritten, the underwriter may (subject to the allocation
priority set forth below) exclude from such registration and underwriting some
or all of the Registrable Securities which would otherwise be underwritten
pursuant hereto. The Company shall so advise all holders of Securities
requesting registration, and the number of Securities that are entitled to be
included in the registration and underwriting shall be allocated in the
following manner: first, the holders of the Securities that demanded such
registration shall be entitled to register all of their shares, to the extent
permitted; and, second, the number of shares that may be included in the
registration and underwriting by each of the Holders and the holders of
Securities that are also contractually entitled to piggy-back upon such
registration shall be reduced, on a pro rata basis (based on the total number of
Common Stock equivalents owned by each), by such minimum number of shares as is
necessary to comply with any limitations imposed by the underwriters upon the
number of shares to be registered. If any holder of Securities disapproves of
the terms of any such underwriting, he may elect to withdraw therefrom by
promptly providing written notice to the Company and the underwriter; provided,
however, that no holder may withdraw following the second business day preceding
effectiveness of the registration statement. Any Registrable



                                     - 19 -
<PAGE>   20


Securities or other Securities excluded in accordance with this Section 7.5(b)
or withdrawn from such underwriting shall be withdrawn from such registration.

     (c) The Company shall obtain the Purchasers' prior written consent before
granting any demand or piggy-back registration rights that have priority over or
parity with the registration rights granted herein to the Holders.

     7.6. Indemnification.

     (a) The Company will indemnify each of the Holders, as applicable, each of
its officers, directors and partners, and each person controlling each of the
Holders, with respect to each registration which has been effected pursuant to
this Section VII, and each underwriter, if any, and each person who controls any
underwriter, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any prospectus or other
document (including any related registration statement, notification or the
like) incident to any such registration or qualification, or based on 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, or
any violation by the Company of the Securities Act or any rule or regulation
thereunder applicable to the Company and relating to action or inaction required
of the Company in connection with any such registration or qualification, and
will reimburse each of the Holders, each of its officers, directors and
partners, and each person controlling each of the Holders, each such underwriter
and each person who controls any such underwriter, for any legal and any other
expense reasonably incurred in connection with investigating and defending any
such claim, loss, damage, liability or action; provided that the Company will
not be liable in any such case to any Holder or underwriter or person
controlling such Holder or underwriter to the extent that any such claim, loss,
damage, liability or expense arises out of or is based on any untrue statement
or omission based upon information furnished in writing to the Company by such
Holder or underwriter or person controlling such Holder or underwriter and
stated to be specifically for use therein; and further provided that the Company
shall not be liable hereunder, whether to the Holders, any underwriter or any
other third party, or any such party's officers, directors, partners or persons
controlling such parties, for the failure of such party to comply with such
party's prospectus delivery requirements.

     (b) Each of the Holders will, if Registrable Securities held by it are
included in the Securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, each of its directors and
officers and each underwriter, if any, of the Company's Securities covered by
such a registration statement, each person who controls the Company or such
underwriter within the meaning of the Securities Act and the rules and
regulations thereunder, each other Holder and each of their officers, directors,
and partners, and each person controlling such other Holder against all claims,
losses, damages, and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement, prospectus, offering circular
or other document made by each Holder, or 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 by


                                     - 20 -

such Holder, and will reimburse the Company and such other Holders, directors,
officers, partners, persons, underwriters or control persons for any legal or
any other expenses reasonably incurred in connection with investigating or
defending any such claim, loss, damage, liability or action, in each case to the
extent, but only to the extent, that such untrue statement (or alleged untrue
statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular or other document in reliance upon and
in conformity with information furnished in writing to the Company by such
Holder and stated to be specifically for use therein; provided, however, that
the obligations of each of the Holders hereunder shall be limited to an amount
equal to the net proceeds to such Holder of Securities sold pursuant to such
registration.

     (c) Each party entitled to indemnification under this Section 7.6 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom provided that counsel for the Indemnifying Party,
who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld) and the Indemnified Party may participate in such
defense at the Indemnified Party's expense (unless (i) the employment of counsel
by such Indemnified Party has been authorized by the Indemnifying Party, or (ii)
the Indemnified Party shall have reasonably concluded that there may be a
conflict of interest between the Indemnifying Party and the Indemnified Party in
the defense of such action, in each of which cases the fees and expenses of one
counsel for all Holders (in addition to local counsel) shall be at the expense
of the Indemnifying Party), and provided further that the failure of any
Indemnified Party to give notice as provided herein, shall not relieve the
Indemnifying Party of its obligations under this Section VII unless the failure
to give such notice materially prejudices the Indemnifying Party. No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation. Each
Indemnified Party shall furnish such information regarding itself or the claim
in question as an Indemnifying Party may reasonably request in writing and as
shall be reasonably required in connection with the defense of such claim and
litigation resulting therefrom.

     (d) If the indemnification provided for in this Section 7.6 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
thereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage or expense 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 which resulted in such loss, liability, claim,
damage or expense as well as any other relevant equitable considerations. The
relative fault of the Indemnifying Party and of the Indemnified Party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue


                                     - 21 -
<PAGE>   22


statement of a material fact or the omission to state a material fact relates to
information supplied by the Indemnifying Party or by the Indemnified Party and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission, and the amount of the net
proceeds to such Holder of Securities sold pursuant to such registration.

     (e) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution relating to obligations among the parties
hereto and the underwriters contained in a negotiated underwriting agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall be controlling.

     7.7. Information by the Holders. Each of the Holders shall furnish to the
Company such information regarding such Holder and the distribution proposed by
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 VII.

     7.8. Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the SEC which may permit the sale of the
restricted securities to the public without registration, the Company agrees to:

             (a) use its best efforts to make and keep public information
     available as those terms are understood and defined in Rule 144 at all
     times;

             (b) use its best efforts to 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 at any time after it has become subject
     to such reporting requirements; and

             (c) so long as any Purchaser owns any Registrable Securities,
     furnish to the Purchaser upon request, a written statement by the Company
     as to its compliance with the current information requirements of Rule 144,
     a copy of the most recent annual or quarterly report of the Company, and
     such other reports and documents so filed as the Purchaser may reasonably
     request in availing itself of any rule or regulation of the SEC allowing
     the Purchaser to sell restricted securities without registration.

     7.9. Assignability of Registration Rights. The Registration Rights granted
pursuant to this Section 7 shall be assignable at the option of each of the
Holders, in whole or in part, to any transferee of Registrable Securities.

indebtedness or guarantee and (ii) faithfully perform, observe and discharge all

faith by appropriate proceedings and if the Company or any subsidiary, as the
case may be, shall have set aside on its books adequate reserves with respect

being diligently conducted and for which adequate reserves in accordance with
generally accepted accounting principles have been provided, except that Company
or such subsidiary, as the case may be, shall pay or cause to be paid all such
accounts payable and claims forthwith upon the commencement of proceedings to
foreclose any lien which is attached as security therefor, unless such
foreclosure is stayed by the filing of an appropriate bond in a manner
reasonably satisfactory to the Purchasers.

subsidiaries or any of the properties or facilities owned, leased or operated by
the Company or any subsidiaries, and (ii) any condition or occurrence on any of

shall deliver to each Purchaser, the Company's plan with respect to removal or
remediation and the Company agrees to take all action which is reasonably
necessary in connection with such action, investigation, condition or occurrence

plan. Without limiting the generality of the foregoing, the Company will not,
and it will not cause or permit any subsidiaries or any ERISA Affiliate to:

             (i) permit any pension plan maintained by the Company, any
     subsidiaries or any ERISA Affiliate to engage in any nonexempt "prohibited

             (iii) terminate any pension plan in a manner which could result in

     or any ERISA Affiliate pursuant to Section 4068 of ERISA, 29 U.S.C. Section
     1368;

             (iv) take any action which would constitute a complete or partial

<PAGE>   27


             (v) permit any condition to exist in connection with any pension
     plan which might constitute grounds for the PBGC to institute proceedings

     such pension plan; or

             (vi) engage in, or permit to exist or occur, any other condition,
     event or transaction with respect to any pension plan which could result in
     the incurrence by the Company, any subsidiaries or any ERISA Affiliate of
     any liability, fine or penalty.

     8.16. Further Assurances. The Company will cooperate with the Purchasers
and execute such further instruments and documents as the Purchasers shall
reasonably request to carry out the transactions contemplated by this Agreement.

     8.17. Transactions with Affiliates and Related Parties. The Company shall
not, and will not permit any of its subsidiaries to, enter into or be a party to
any transaction or arrangement with any Affiliate (as defined below) (including,
without limitation, the purchase from, sale to or exchange of property with, or
the rendering of any service by or for, any Affiliate) or, any shareholder,
employee or officer which is not an Affiliate, except in the ordinary course of
business and pursuant to the reasonable requirements of the Company's business
and upon fair and reasonable terms no less favorable to the Company or any
subsidiary than would be obtained in a comparable arm's length transaction with
a third party not an Affiliate. Notwithstanding any provision of this Agreement
to the contrary, neither the Company nor any subsidiary shall make any loans or
advances to any employee, officer or family member or relative, or related party
of any officer, employee or shareholder of the Company or to any Affiliate
(except for the advance of business and travel expenses incurred by employees of
the Company and its Subsidiaries in the ordinary course of business).
"Affiliate" means any entity or person that controls, is controlled by, or is
under common control with the Company, with control meaning the beneficial
ownership of or the ability to vote over 20% of the voting interests of an
entity.

     8.18. Board Representation. The Company will use its best efforts to cause
a designee of Essex to be nominated and elected to its Board of Directors until
the later of (i) the fifth anniversary of the Closing Date, and (ii) the date on
which Essex fails to own in the aggregate more than 5% of the issued and
outstanding Common Stock. The Company will use its best efforts to cause a
designee of Invesco to be nominated and elected to its Board of Directors until
the later of (i) the fifth anniversary of the Closing Date or (ii) the date on
which Invesco fails to own in the aggregate more than 5% of the issued and
outstanding Common Stock. The Company will cause each of its directors and
executive officers to enter into a voting agreement containing the terms set
forth in Section 2 of the Co-Sale and Voting Agreement. If either Essex or
Invesco decide not to designate a person to be elected to the Board of
Directors, then the Company shall provide Essex or Invesco, as applicable, with
all notices to Board meetings and permit a person designated by such
Purchaser(s) to attend and observe all formal and informal Board meetings.

     8.19. The Company will take such action as shall be required to cause the
Board of Directors of the Company to meet with such frequency as a majority of
the Board of Directors shall determine, but not less often than quarterly. The

Committees thereof.

     8.20. Board Committees. The Company's Compensation Committee shall include
the two directors who are the designees of Essex and Invesco. The Company's
Audit Committee shall include the two directors who are the designees of Essex

meetings and permit a person designated by Essex and a person designated by
Invesco to attend and observe all formal and informal Audit and Compensation
Committee meetings.

the then current fiscal year of the Company. The Company shall not make any
capital expenditure which is not included in such approved budget or engage in
any search for any new executive employee without the prior consent of the Board
of Directors.

     8.22. Proprietary Information Agreement. Each officer and employee of the
Company responsible for proprietary information shall execute a Proprietary

     8.23. Intellectual Property. The Company will take all necessary actions to
secure, register and protect the Company's interest in any future intellectual
property rights and will continue to do so with respect to current and future
intellectual property rights so as not to adversely affect the validity or
enforceability of the Company's intellectual property rights.

     8.24. Subscription Rights. The Company hereby grants each Purchaser the
right to subscribe to additional securities to preserve its percentage interest
in the Company on the following terms and conditions:

             (a) As to each Purchaser, the subscription right granted hereby
     shall be in effect for two years after the Closing Date.

             (b) If at any time this subscription right is in effect, the Board
     of Directors of the Company shall authorize the issuance of shares of
     Common Stock or the issuance of warrants, rights, options or shares of
     capital stock or securities exercisable for or convertible into Common
     Stock (except, in each case, for issuances (i) to employees, consultants,
     scientific advisors, officers, directors, or vendors (including equipment
     lessors) of the Company pursuant to stock option,



                                     - 28 -
<PAGE>   29


     stock purchase, stock bonus or stock incentive plans or pursuant to written
     contracts relating to the employment, engagement or compensation of such
     persons or entities, (ii) in connection with the acquisition by the Company
     of another entity, (iii) any Warrant Stock issued upon exercise of the
     Warrants, (iv) in connection with a public offering, (v) in connection with
     the exercise of any outstanding options, warrants or other rights to
     acquire Common Stock which are outstanding as of the Closing Date and which
     are disclosed in the Disclosure Schedules, or (vi) of an aggregate of
     165,000 shares of Common Stock to the lenders a party to the Credit
     Agreement solely to the extent required under the Credit Agreement
     Amendment), then prior to the issuance of such securities, the Company
     shall, with respect to each such issuance and each such time, offer each
     Purchaser the right to purchase, on the same or equivalent terms, that
     number of authorized but unissued shares of Common Stock and other
     securities convertible into or exercisable for Common Stock in the same
     proportions as are proposed to be issued as shall be necessary to maintain
     its percentage interest in the Company at that percentage (the "Target
     Percentage") as shall equal such Purchaser's percentage interest in the
     Common Stock of the Company existing immediately prior to the proposed
     issuance of such securities. In each such case, the calculation of the
     Target Percentage shall be based on the total number of shares of Common
     Stock that would be outstanding (i) upon conversion of any outstanding
     securities of the Company convertible into Common Stock, (ii) upon exercise
     of any then outstanding warrants of the Company and (iii) upon exercise of
     any then outstanding stock options or stock purchase rights of the Company.

             (c) Unless otherwise agreed to by all of the Purchasers, any offer
     of Common Stock (or other securities) to the Purchasers under this
     subscription right shall be made by notice in writing at least thirty (30)
     days prior to the date on which the Company intends to issue and sell
     securities to any person other than any Purchaser. Such notice shall set
     forth the price, terms and other relevant conditions upon which such
     Securities are proposed to be sold, as well as the amount of securities
     offered to the Purchasers under this subscription right. Not later than
     twenty (20) days after receipt of such notice, each Purchaser shall notify
     the Company in writing whether it elects to purchase all or any of the
     securities offered to it pursuant to such notice, stating the amount of
     such securities it wishes to purchase. If a Purchaser elects to
     participate, such Purchaser shall be required to purchase any combination
     of securities being offered in the same proportions as are being sold to
     other investors. If a Purchaser shall elect to purchase any securities
     pursuant to the notice from the Company, the securities which it elects to
     purchase shall be issued and sold to it by the Company at the same price
     per share as is specified in the notice.

             (d) In the event the Purchasers fail to exercise their subscription
     rights within said twenty (20) day period, the Company shall have one
     hundred twenty (120) days thereafter to sell or enter into any agreement
     (pursuant to which the sale of securities covered thereby shall be closed,
     if at all, within forty-five (45)



                                     - 29 -

     days from the date of said agreement) to sell the securities in respect of
     which such Purchasers' subscription rights were not exercised, at a price
     and upon terms no more favorable to the purchasers) thereof than those
     specified in the Company's notice to such Purchasers. In the event the
     Company has not sold such securities within such 120-day period or entered
     into an agreement to sell the securities within such 120-day period, the
     Company shall not thereafter issue or sell such securities, without first
     offering such securities to the Purchasers in the manner provided above.

     8.25. Consultation. If the Company desires to retain the extraordinary
services of any Purchaser to serve as a special consultant to the Company in
mergers and acquisitions or financial consulting, such engagement shall be
approved by a majority of the disinterested members of the Board of Directors.
If such engagement is so approved, such Purchaser shall be paid all of its
out-of-pocket expenses currently and any other reasonable fee approved by the
Board of Directors on a non-contingent basis.

     8.26. Dividends and Redemptions. For two years from the date hereof and so
long as any Share, Warrant or Warrant Stock is outstanding, the Company shall
not declare, set aside or pay any dividend or make any distribution in respect
of its Common Stock, or redeem, purchase or otherwise acquire any of its Common
Stock except for the repurchase of Common Stock from Physician Practices in
connection with settling disputes or restructuring outstanding Physician
Agreements.

     8.27. Trading Market. As long as the Purchasers own Common Stock, Warrants
or Warrant Stock, the Company shall use its best efforts to cause its Common
Stock to continue to be traded on the Nasdaq Stock Market or cause the Common
Stock to be listed on the New York Stock Exchange or the Nasdaq Stock Market.

     8.28. Reporting Stock. So long as any Purchaser beneficially owns any
Shares, Warrants or Warrant Stock, the Company shall timely file all reports
required to be filed with the SEC pursuant to the Exchange Act, and the Company
shall not terminate its status as an issuer required to file reports under the
Exchange Act even if the Exchange Act or the rules and regulations thereunder
would permit such termination.

     8.29. Additional Issuance of Common Stock. For a period of 12 months from
the Closing Date, whenever the Warrant Price of the Warrants is reduced in
accordance with Section 2.2.1 of the Warrants, the Company shall issue to the
Purchaser an additional number of shares of Common Stock at a purchase price of
$.001 per share equal to (a)(1) 2,500,000 plus the number of shares of Common
Stock previously issued under this Section 8.29, multiplied by (2) a fraction,
the numerator of which is the Warrant Price immediately prior to such event and
the denominator of which is the Warrant Price immediately after such event, less
(b) 2,500,000 plus the number of shares of Common Stock previously issued under
this Section 8.29.

                                   SECTION IX

  RESTRICTIONS ON TRANSFERABILITY OF SECURITIES; COMPLIANCE WITH SECURITIES ACT

     9.1. Certain Definitions. As used in this Agreement, the following terms
shall have the following respective meanings:

     An "affiliate" of a person is another person that directly or indirectly,
through one or more intermediaries, controls, is controlled by, or is under
common control with, such first person.

     "Exchange Act" shall mean the Securities Exchange Act of 1934, as amended,
or any similar federal statute and the rules and regulations of the SEC
thereunder, all as the same shall be in effect at the time.

     "Restricted Securities" shall mean the securities of the Company required
to bear the legend set forth in Section 9.3 hereof.

     "Securities Act" shall mean the Securities Act of 1933, as amended, or any
similar federal statute and the rules and regulations of the SEC thereunder, all
as the same shall be in effect at the time.

     9.2. Restrictions on Transferability. Each Purchaser covenants that it will
not sell or otherwise transfer any of the Shares or Warrant Stock acquired
hereunder (other than pursuant to Rule 144 or any similar or analogous rule or
rules) except pursuant to an effective registration under the Securities Act or
in a transaction which, in the opinion of counsel reasonably satisfactory to the
Company, qualifies as an exempt transaction under the Securities Act and the
rules and regulations promulgated thereunder.

     9.3. Restrictive Legend. Each certificate representing (i) the Shares or
Warrant Stock, and (ii) any other securities issued in respect of the Shares,
Warrants or Warrant Stock upon any stock split, stock dividend,
recapitalization, merger, consolidation or similar event, shall (unless
otherwise permitted by the provisions of Section 9.4 below) be stamped or
otherwise imprinted with a legend in the following form (in addition to any
legend required under applicable state securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.
     SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED (OTHER THAN PURSUANT TO RULE 144
     OR ANY SIMILAR OR ANALOGOUS RULE OR RULES) IN THE ABSENCE OF SUCH
     REGISTRATION UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY
     ACCEPTABLE TO IT STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE
     REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT. COPIES OF
     THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND



                                     - 31 -
<PAGE>   32


     RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST
     MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE
     CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION.

     Each Purchaser and holder consents to the Company making a notation on its
records and giving instructions to any transfer agent of the Shares or the
Warrant Stock in order to implement the restrictions on transfer established in
this Section 9.

     9.4. Notice of Proposed Transfers. The holder of each certificate
representing Restricted Securities, by acceptance thereof, agrees to comply in
all respects with the provisions of this Section 9.4. Prior to any proposed
sale, assignment, transfer or pledge of any Restricted Securities (other than
(i) transfers not involving a change in beneficial ownership or (ii)
transactions involving the distribution without consideration of Restricted
Securities by any of the Purchasers to any of its partners, or retired partners,
or to the estate of any of its partners or retired partners), unless there is in
effect a registration statement under the Securities Act covering the proposed
transfer, the holder thereof shall give written notice to the Company of such
holder's intention to effect such transfer, sale, assignment or pledge. Each
such notice shall describe the manner and circumstances of the proposed
transfer, sale, assignment or pledge in sufficient detail, and shall be
accompanied, at such holder's expense by either (i) unqualified written opinion
of legal counsel who shall, and whose legal opinion shall be, reasonably
satisfactory to the Company addressed to the Company, to the effect that the
proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act, or (ii) a "no action" letter from the SEC
to the effect that the transfer of such securities without registration will not
result in a recommendation by the staff of the SEC that action be taken with
respect thereto, whereupon the holder of such Restricted Securities shall be
entitled to transfer such Restricted Securities in accordance with the terms of
the notice delivered by the holder to the Company. Each certificate evidencing
the Restricted Securities transferred as above provided shall bear, except if
such transfer is made pursuant to Rule 144, the appropriate restrictive legend
set forth in Section 9.3 above, except that such certificate shall not bear such
restrictive legend if in the opinion of counsel for such holder and the Company
such legend is not required in order to establish compliance with any provision
of the Securities Act.

                                   SECTION X

                                   TERMINATION

     10.1. Consummation. Subject to the terms and conditions provided herein,
each party agrees to use all reasonable commercial efforts to take, or cause to
be taken all actions and to do, or cause to be done all things necessary, proper
or advisable under applicable laws and regulations to consummate and make
effective the transactions contemplated by this Agreement in accordance with its
terms.

     10.2. Termination or Abandonment. Notwithstanding anything contained in
this Agreement to the contrary, this Agreement may be terminated and abandoned

                                     - 32 -
<PAGE>   33


     (a) by the mutual written consent of the Company and the Purchasers;

     (b) by either the Purchasers or the Company if any court of competent
jurisdiction or governmental body, authority or agency having jurisdiction shall
have issued an order, decree or ruling or taken any other action restraining,
enjoining or otherwise prohibiting the transactions contemplated by this
Agreement and such order, decree, ruling or other action shall have become final
and nonappealable;

     (c) by either party if the Closing shall not have occurred within fifteen
(15) days of the date of this Agreement.

     10.3. Effect of Termination. If any party terminates this Agreement
pursuant to Section 10.2 above, all obligations of the parties hereunder shall
terminate without any liability of any party to any other party (except for any
liability of any party then in breach in which case the nonbreaching party
reserves the right to seek all available remedies); provided, however, that the
provisions of Section 10.3 and Section 11 shall survive termination of this
Agreement. Nothing in this Section 10.3 shall relieve any party from liability
for any willful or intentional breach of this Agreement.

                                   SECTION XI

                                  MISCELLANEOUS

     11.1. Governing Law. This Agreement shall be governed in all respects by
the internal laws of the State of Delaware.

     11.2. Survival. The representations, warranties, covenants and agreements
made herein shall survive any investigation made by the Purchaser and the
closing of the transactions contemplated hereby for a period of two years from
the date of such closing.

     11.3. Successors and Assigns. Except as otherwise provided herein, the
provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, heirs, executors and administrators of the parties hereto,
provided, however, that the rights of each Purchaser to purchase the Shares
shall not be assignable without the consent of the Company.

     11.4. Entire Agreement; Amendment. This Agreement and the other documents
delivered pursuant hereto at the Closing constitute the full and entire
understanding and agreement between the parties with regard to the subjects
hereof and thereof, and no party shall be liable or bound to any other party in
any manner by any warranties, representations or covenants except as
specifically set forth herein or therein. Except as expressly provided herein,
neither this Agreement nor any term hereof may be amended, waived, discharged or
terminated other than by a written instrument signed by the party against whom
enforcement of any such amendment, waiver, discharge or termination is sought;
provided, however, Purchasers owning more than fifty (50%) of the Shares and the
Warrant Stock may, with the Company's prior written consent, waive, modify or
amend on behalf of all Purchasers, any provisions hereof.

     11.5. Notices, etc. All notices and other communications required or
permitted hereunder shall be in writing and shall be mailed by registered or
certified mail, postage prepaid, or otherwise delivered by hand or by messenger,
addressed (a) if to a Purchaser, at such Purchaser's address set forth on the
signature page hereof, or at such other address as the Purchaser shall have
furnished to the Company in writing, or (b) if to any other holder of any
Shares, Warrants or Warrant Stock, at such address as such holder shall have
furnished the Company in writing, or, until any such holder so furnishes an
address to the Company, then to and at the address of the last holder of such
Shares, Warrants or Warrant Stock who has so furnished an address to the
Company, or (c) if to the Company, one copy should be sent to its address set
forth on the cover page of this Agreement and addressed to the attention of the
Corporate Secretary, or at such other address as the Company shall have
furnished to the Purchasers.

     Each such notice or other communication shall for all purposes of this
Agreement be treated as effective or having been given when delivered if
delivered personally, or, if sent by mail, at the earlier of its receipt or 72
hours after the same has been deposited in a regularly maintained receptacle for
the deposit of the United States mail, addressed and mailed as aforesaid.

     11.6. Delays or Omissions. Except as expressly provided herein, no delay or
omission to exercise any right, power or remedy accruing to any holder of any
Shares, upon any breach or default of the Company under this Agreement, shall
impair any such right, power or remedy of such holder nor shall it be construed
to be a waiver of any such breach or default, or an acquiescence therein, or of
or in any similar breach or default thereafter occurring; nor shall any waiver
of any single breach or default be deemed a waiver of any other breach or
default theretofore or thereafter occurring. Except as provided in Section 10.4
hereof, any waiver, provisions or conditions of this agreement, must be in
writing and shall be effective only to the extent specifically set forth in such
writing. All remedies, either under this Agreement or by law or otherwise
afforded to any holder, shall be cumulative and not alternative.

     11.7. Expenses. Each of the Company and the Purchasers shall bear their own
expenses incurred on their behalf with respect to this Agreement and the
transactions contemplated hereby, including, but not limited to, the fees and
disbursements of Purchasers' legal counsel and out-of-pocket expenses. In
addition, the Company shall pay for all broker and finders fees incurred by the
Company as a result of the consummation of the transactions contemplated hereby.

     11.8. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be enforceable against the parties actually
executing such counterparts, and all of which together shall constitute one
instrument.

     11.9. Severability. In the event that any provision of this Agreement
becomes or is declared by a court of competent jurisdiction to be illegal,
unenforceable or void, this Agreement shall continue in full force and effect
without said provision; provided that no such severability shall be effective if
it materially changes the economic benefit of this Agreement to any party.

     11.10. Titles and Subtitles. The titles and subtitles used in this
Agreement are used for convenience only and are not considered in construing or
interpreting this Agreement.

     11.11. Announcement. No announcement of the terms of this Agreement or the
transactions contemplated hereby shall be made by any party without the written
approval of the other party (which consent shall not be unreasonably withheld)
until the Closing, except for information required to be sent to stockholders of
the Company to obtain stockholder approval as required by the NASD.

     11.12. Injunctive Relief. The parties hereto acknowledge and agree that any
breach of this Agreement by a party will cause irreparable injury to the other
party and that any damages will not provide an adequate remedy to the injured
party. Consequently, each party shall have the right to seek and obtain
injunctive or other equitable relief to enforce any of its rights or the
obligations of any of the other parties contained in this Agreement.

                  3 .2 Entire Agreement. This Agreement, the Exhibits and
Schedules hereto, constitute the full and entire understanding and agreement

liable or bound to any other in any manner by any representations, warranties
covenants and agreements except as specifically set forth herein and therein.

                  3.3 Severability. In case any provision of the Agreement shall
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.

                  3.4 Counterparts. This Agreement may be executed in two
counterparts, each of which shall be an original, but which shall together
constitute one instrument.

                                                                       EXHIBIT D

                           COSALE AND VOTING AGREEMENT

                  This CoSale and Voting Agreement (this "Agreement") is made as
of March __, 2000 among HealthGrades.com, Inc., a Delaware corporation (the
"Company"), Essex Woodlands Health Ventures Fund IV, L.P., an Illinois
partnership ("Essex"), PaineWebber, as custodian for William J. Punk, I.R.A.
("PW"), Punk, Ziegal & Company Investors, L.L.C. ("Punk"), and Chancellor V, L.
P. ("Invesco" and with Punk, PW and Essex collectively the "Investors"), Kerry
Hicks ("Hicks"), Paul Davis ("Davis"), David Hicks ("D. Hicks") and Patrick
Jaeckle ("Jaeckle" and with Hicks, Davis and D. Hicks collectively, the
"Founders") (the Investors and the Founders are sometimes referred to herein as
the "Shareholders").

                                    RECITALS

         A. The Founders own certain outstanding shares of Common Stock, par
value $0.001 per share ("Common Stock"), of the Company.

         B. The Investors have purchased shares of Common Stock and warrants
(the "Warrants") to purchase Common Stock (the "Equity Securities") pursuant to
a Amended and Restated Stock Purchase Agreement dated March 3, 2000.

         C. In order to induce the Investors to purchase the Common Stock, the
Shareholders have agreed to provide certain co-sale and voting rights with
respect to their holdings of the Company's Common Stock.

         NOW, THEREFORE, in consideration of the mutual promises and other
consideration hereinafter set forth, the adequacy and receipt of which is hereby
acknowledged by the parties hereto, the parties agree as follows:

         1. Right of Co-Sale.

         1.1. The Right. If at any time any Founder (a "Selling Founder")
proposes to sell shares of Common Stock pursuant to a bona fide offer from a
party or parties other than other Founders or any of the Investors and such sale
is a private transaction, then the Selling Founder shall provide notice of such
proposed sale to the Investors, such notice containing (i) notice that the
Selling Founder intends on selling his shares, (ii) the material terms and
conditions of such sale, (iii) any written materials or agreements setting forth
the agreement between the Selling Founder and the purchaser, and (iv) each
Investor's "pro rata portion" (as defined below) in the sale (assuming all
Investors elect to be Co-Sellers). The Investors shall be entitled to sell their
pro rata portion on the same terms and conditions as the Selling Founder. If any
of the Investors notifies the Selling Founder in writing within 10 days after
receipt of the notification of such proposed sale from the Selling Founder, such
Investor or Investors (the "Co-Seller") shall have the right to sell up to its
pro rata portion of Common Stock which the Selling Founder proposes to sell to
such third party; whereupon the Selling Founder shall assign so much of his
interest in the agreement of sale as is proportionate to each Co-Seller's pro
rata portion in the sale of Common Stock (or such lesser amount if so elected by
such Co-Seller) and each Co-Seller shall
<PAGE>   44


assume its respective part of the obligations of the Selling Founder under such
agreement, provided, however, no Co-Seller shall be required to give any
covenants, representations or warranties other than with respect to title to its
Equity Securities. For the purposes of this Section 1.1 the "pro rata portion"
which each Co-Seller shall be entitled to sell shall be an amount of Equity
Securities (assuming the issuance of all shares of Common Stock, issuable upon
exercise of the Warrants) equal to a fraction of the total amount of Common
Stock proposed to be sold, the numerator of which is the aggregate of all Equity
Securities (assuming the conversion of all such securities to Common Stock)
which are then held by such Co-Seller and the denominator is the aggregate of
all Common Stock then held by the Selling Founder and all Equity Securities
(assuming the conversion of all such securities to Common Stock) then held by
all Co-Sellers who have elected to exercise their co-sale rights. Each of the
Investors shall notify the Selling Founder whether it elects to sell an amount
equal to or less than its pro rata portion of the Common Stock so offered

         1.2. Failure to Notify. If within 10 days after the Selling Founder
gives the aforesaid notice to Investors, none of the Investors notifies the
Selling Founder that it desires to sell any or all of its pro rata portion of
the Common Stock described in such notice at the price and on the terms and
conditions set forth therein, then the Selling Founder may sell during the
120-day period immediately following the expiration of such 10-day period such
Common Stock as to which the Investors did not indicate a desire to sell to
other persons at the same price and upon the same terms and conditions as those
set forth in the notice. In the event the Selling Founder has not sold the
Common Stock on the same terms and conditions as those set forth in the notice
within such 120-day period, the Selling Founder shall not thereafter sell any
Common Stock without first notifying the Investors in the manner provided above.

         1.3. Limitations to Right of Co-Sale. Without regard and not subject to
the provisions of this Agreement:

                 (a) a Founder may sell or otherwise assign for consideration or
         gift Common Stock to any or all of his ancestors, descendants, spouse,
         employees of the Company or to a custodian, trustee (including a
         trustee of a voting trust), executor, or other fiduciary for the
         account of or a trust for the benefit of his ancestors, descendants or
         spouse, provided that each such transferee or assignee, prior to the
         completion of the sale, transfer, gift or assignment, shall have
         executed documents assuming the obligations of a Founder under this
         Agreement with respect to the transferred securities;

                 (b) a Founder may sell shares of Common Stock, the proceeds of
         which are used to exercise stock options issued under the Company's
         stock option plan;

                 (c) a Founder may pledge and/or sell shares of Common Stock to
         the Company; and

                 (d) a Founder may sell shares of Common Stock in the open
         market in amounts not to exceed the limitations permitted under Rule
         144.

         2.1. Designees to Board of Directors. The Shareholders agree to vote
all securities of the Company over which they have voting control and to take
all other necessary or desirable actions within their control (whether as
shareholders, directors or officers of the Company or otherwise, and including
without limitation attendance at meetings in person or by proxy for purposes of
obtaining a quorum and execution of written consents in lieu of meetings), and
the Company shall take all necessary and desirable actions within its control
(including, without limitation, calling special board and shareholder meetings),
so that:

                 (a) The Company shall have a Board of Directors comprising of
         no more than eight (8) members;

                 (b) At the option of Essex, one designee of Essex and, at the
         option of Invesco, one designee of Invesco shall be elected to the
         Board of Directors; and

                 (c) In the event that a director designated by Essex or Invesco
         for any reason ceases to serve as a member of the Board of Directors
         during his or her term of office, at the option of Essex or Invesco, as
         applicable, the resulting vacancy on the Board of Directors shall be
         filled by a designee of Essex or Invesco, as applicable.

         3. Committees.

applicable, the directors designated by Essex and Invesco shall serve as members
of the Audit Committee of the Company.

         3.2. Compensation Committee. At the option of Essex and Invesco, as
applicable, the directors designated by Essex and Invesco shall serve as members
of the Compensation Committee.

rights and obligations of the Shareholders hereto, shall become effective on the
date hereof, and shall terminate:

                 (a) with respect to Section 1 above, upon the earlier of: (i)
         when the Investors cease to own in the aggregate five percent (5%) or
         more of the issued and outstanding shares of Common Stock of the
         Company, and (ii) on the third anniversary of the date hereof;

                 (b) with respect to Sections 2 and 3 above and the obligation

<PAGE>   46


         upon the later of (i) the fifth anniversary of the date hereof, and
         (ii) the date on which Essex fails to own in the aggregate more than 5%
         of the issued and outstanding Common Stock;

                 (c) with respect to Sections 2 and 3 above and the obligation

         this Agreement will terminate upon a Change of Control Transaction. A
         "Change of Control Transaction" shall mean (i) a transaction in which
         all of the shares of Common Stock are exchanged for cash or other
         securities of a third party and such transaction results in the holders
         of Common Stock holding less than fifty percent (50%) of the voting
         power of the surviving entity, or (ii) the sale or transfer of all or
         substantially all of the Company's assets.

successors and assigns.

         4.5. Complete Agreement; Amendments. This Agreement constitutes the
full and complete agreement of the parties hereto with respect to the subject
matter hereof. This Agreement supersedes and takes the place of all prior
agreements relating to its subject matter. No amendment, modification or
termination of any provisions of this Agreement shall be valid unless in writing
and signed by the Company and each of the Shareholders.

         4.6. Severability. Should any part of this Agreement for any reason be
declared invalid, such decision shall not affect the validity of any remaining
portion, which remaining portion shall remain in force and effect as if this
Agreement had been executed with the invalid portion thereof eliminated and it
is hereby declared the intention of the parties hereto that they would have
executed the remaining portion of this Agreement without including therein any
such part, parts, or portion which may, for any reason, be hereafter declared
invalid.
