                  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

                  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

         1.4 NOTICE OF PROPOSED TRANSFERS. The holder of each certificate

transfer not involving a change in beneficial ownership or (ii) in 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, if requested by the Company,
shall be accompanied, at such holder's expense, by either (i) an unqualified
written opinion of legal counsel who shall be, 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
Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
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. It is agreed that the Company will not request an opinion of counsel
for the Holder for transactions made in reliance on Rule 144 under the
Securities Act except in unusual circumstances, the existence of which shall be
determined in good faith by the Board of Directors of 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 1.3 above, except that such

         1.5      REQUESTED REGISTRATION.

                  (a) Request for Registration. In case, after the earlier to
occur of (x) September 1, 1997 or (y) the date six months after the closing of
the Company's initial public offering, the Company shall receive from Initiating
Holders a written request that the Company effect any registration,
qualification or compliance with respect to Registrable Securities, the Company
will:

                           (i) promptly give written notice of the proposed
registration, qualification or compliance to all other Holders; and

                           (ii) as soon as practicable, use its best efforts to
effect such registration, qualification or compliance (including, without
limitation, appropriate qualification under applicable blue sky or other state
securities laws and appropriate compliance with applicable regulations issued
under the Securities Act and any other governmental requirements or regulations)
as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities of any Holder or Holders joining in such request as are specified in
a written request received by the Company within 20 days after receipt of such
written notice from the Company;

         Provided, however, that the Company shall not be obligated to take any
action to effect any such registration, qualification or compliance pursuant to
this Section 1.5:

                                    (A) In any particular jurisdiction in which
the Company would be required to execute a general consent to service of process
in effecting such registration, qualification or compliance unless the Company
is already subject to service in such jurisdiction and except as may be required
by the Securities Act;

                                    (B) During the period starting with the date
60 days prior to the Company's estimated date of filing of, and ending on the
date six months immediately following the effective date of, any registration
statement pertaining to securities of the Company (other than a registration of
securities in a Rule 145 transaction or with respect to an employee benefit
plan), provided that the Company is actively employing in good faith all
reasonable efforts to cause such registration statement to become effective;

                                    (C) Unless the Registrable Securities sought
to be registered by all Initiating Holders and Holders pursuant to this Section
1.5 comprises at least 25% of all their outstanding Registrable Securities,
except that such 25% requirement shall not apply if the anticipated aggregate
offering price, net of underwriting discounts and commissions, of all Registered
Securities sought to be registered by all Initiating Holders and other Holders
pursuant to this Section 1.5, would exceed $5,000,000;

                                    (E) After the Company has effected two such
registrations pursuant to this subparagraph 1.5(a), and such registrations have
been declared or ordered effective;


                                       -5-
<PAGE>   6
                                    (F) If the Company shall furnish to such
Holders a certificate signed by the President of the Company stating that in the
good faith judgment of the Board of Directors it would be seriously detrimental
to the Company or its shareholders for a registration statement to be filed in
the near future, then the Company's obligation to use its best efforts to
register, qualify or comply under this Section 1.5 shall be deferred for a
period not to exceed 120 days from the date of receipt of written request from
the Initiating Holders; provided, however, that the Company shall not exercise
the right to defer registration granted pursuant to this paragraph (E) more than
one time in any twelve month period.

         Subject to the foregoing clauses (A) through (E), the Company shall
file a registration statement covering the Registrable Securities so requested
to be registered as soon as practicable after receipt of the request or requests
of the Initiating Holders, but in any event within 120 days of such request or
requests.

                  (b) Underwriting. In the event that a registration pursuant to
Section 1.5 is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the notice given pursuant to
Section 1.5(a)(i). In such event, the right of any Holder to registration
pursuant to Section 1.5 shall be conditioned upon such Holder's participation in
the underwriting arrangements required by this Section 1.5, and the inclusion of
such Holder's Registrable Securities in the underwriting to the extent requested
shall be limited to the extent provided herein.

         The Company shall (together with all Holders proposing to distribute
their securities through such underwriting) enter into an underwriting agreement
in customary form with the managing underwriter selected for such underwriting
by a majority in interest of the Initiating Holders, but subject to the
Company's reasonable approval. Notwithstanding any other provision of this
Section 1.5, if the managing underwriter advises the Initiating Holders in
writing that marketing factors require a limitation of the number of shares to
be underwritten, then the Company shall so advise all Holders of Registrable
Securities and the number of shares of Registrable Securities that may be
included in the registration and underwriting shall be allocated among all
Holders thereof in proportion, as nearly as practicable, to the respective
amounts of Registrable Securities held by such Holders at the time of filing the
registration statement. No Registrable Securities excluded from the underwriting
by reason of the underwriter's marketing limitation shall be included in such
registration. To facilitate the allocation of shares in accordance with the
above provisions, the Company or the underwriters may round the number of shares
allocated to any Holder to the nearest 100 shares.

         If any Holder of Registrable Securities disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, the managing underwriter and the Initiating Holders. Any securities
excluded or withdrawn from such underwriting, in the event that such
underwriting represents the initial underwritten public offering of the
Company's securities, shall be withdrawn from such registration, and shall not
be transferred in a public distribution prior to 120 days after the effective
date of the registration statement relating thereto, or such other shorter
period of time as the underwriters may require.

         1.6      COMPANY REGISTRATION.

                  (a) Notice of Registration. If at any time or from time to
time the Company shall determine to register any of its securities, either for
its own account or the account of a security holder or holders, other than (i) a
registration relating solely to employee benefit plans, or (ii) a registration
relating solely to a Commission Rule 145 transaction, the Company will:

                           (i) promptly give to each Holder written notice
thereof; and

                           (ii) include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within 20 days after receipt of such written notice from the
Company, by any Holder.

                  (b) Underwriting. If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 1.6(a)(i). In such event the right of any Holder to
registration pursuant to Section 1.6 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company.
Notwithstanding any other provision of this Section 1.6, if the managing
underwriter determines that marketing factors require a limitation of the number
of shares to be underwritten, the managing underwriter may limit the number of
Registrable Securities to be included in such registration and underwriting or
may exclude Registrable Securities entirely from such registration if the
registration is the first registered offering for the sale of the Company's
securities to the general public and thereafter may limit Registrable Securities
to not less than 20% of the registration. In such event, the Company shall
advise all Holders of Registrable Securities which would otherwise be registered
and underwritten pursuant hereto, and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated among all Holders in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities held by such Holders. If any Holder
disapproves of the terms of any such underwriting, he may elect to withdraw
therefrom by written notice to the Company and the managing underwriter. Any
securities excluded or withdrawn from such underwriting shall be withdrawn from
such registration, and shall not be transferred in a public distribution prior
to 120 days after the effective date of the registration statement relating
thereto, or such other shorter period of time as the underwriters may require.

                  (c) Right to Terminate Registration. The Company shall have
the right to terminate or withdraw any registration initiated by it under this
Section 1.6 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration.

         1.7      REGISTRATION ON FORM S-3.

                  (a) Subject to the remainder of this Section 1, and unless
Rule 144 is available for effecting the proposed transfer, in the event that the
Company receives from the Holders a written request that the Company file a
registration statement on Form S-3 (or any successor form to Form S-3) for a
public offering of shares of the Registrable Securities the reasonably
anticipated aggregate price to the public of which, would exceed $1,000,000 and
the Company is a registrant entitled to use Form S-3 to register the Registrable
Securities for such an offering, the Company shall: (i) promptly give written
notice of the proposed registration to all other Holders of Registrable
Securities and (ii) use its best efforts to cause, as soon as practicable, all
Registrable Securities to be registered as may be so requested for the offering
on such form and to cause such Registrable Securities to be qualified in such
jurisdictions as the Holder or Holders may reasonably request; provided,
however, that the Company shall not be required to effect more than three
registrations pursuant to this Section 1.7. The substantive provisions of
Section 1.5(b) shall be applicable to each registration initiated under this
Section 1.7.

                  (b) Notwithstanding the foregoing, the Company shall not be
obligated to take any action pursuant to this Section 1.7: (i) in any particular
jurisdiction in which the Company would be required to execute a general consent
to service of process in effecting such registration, qualification or
compliance unless the Company is already subject to service in such jurisdiction
and except as may be required by the Securities Act; or (ii) if the Company
shall furnish to such Holder a certificate signed by the President of the
Company stating that in the good faith judgment of the Board of Directors it
would be seriously detrimental to the Company or its shareholders for
registration statements to be filed in the near future, then the Company's
obligation to use its best efforts to file a registration statement shall be
deferred for a period not to exceed 120 days from the receipt of the request to
file such registration by such Holder, provided, however, that the Company shall
not exercise the right to defer registration granted by this subparagraph
(b)(ii) more than once in any twelve month period.

         1.8 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the
Closing Date, the Company shall not enter into any agreement granting any holder
or prospective holder of any securities of the Company registration rights with
respect to such securities unless (i) such new registration rights, including
standoff obligations, are on a pari passu basis with those rights of the Holders
hereunder, or (ii) such new registration rights, including standoff obligations,
are subordinate to the registration rights granted Holders hereunder.

the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will with all deliberate speed:

                  (a) Prepare and file with the Commission a registration
statement with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least 180 days or
until the distribution described in the Registration Statement has been
completed;

                  (b) Furnish to the Holders participating in such registration
and to the underwriters of the securities being registered such reasonable

prospectus and such other documents as such underwriters may reasonably request
in order to facilitate the public offering of such securities;

                  (c) Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statements as may be necessary to comply with the

securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions; and

                  (e) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its

                  (b) Each Holder will, if Registrable Securities held by such
Holder 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, 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 Section 15 of the
Securities Act, and each other such Holder, each of its officers, directors and
partners and each person controlling such Holder within the meaning of Section
15 of the Securities Act, 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, 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, and
will reimburse the Company, such Holders, such 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 written information furnished to the Company by an instrument
duly executed by such Holder and stated to be specifically for use therein.

                  (c) Each party entitled to indemnification under this Section
1.11 (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


                                      -10-
<PAGE>   11
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 litigation,
shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, 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 1.11 unless the failure
to give such notice is materially prejudicial to an Indemnifying Party's ability
to defend such action and provided further, that the Indemnifying Party shall
not assume the defense for matters as to which there is a conflict of interest
or separate and different defenses. 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. No Indemnifying Party shall be liable for
indemnification hereunder with respect to any settlement or consent to judgment,
in connection with any claim or litigation to which these indemnification
provisions apply, that has been entered into without the prior consent of the
Indemnifying Party (which consent will not be unreasonably withheld).

         1.12 INFORMATION BY HOLDER. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders, the Registrable Securities held by
them and the distribution proposed by such Holder or Holders as the Company may
request in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Section 1.

         1.13 RULE 144 REPORTING. With a view to making available the benefits
of certain rules and regulations of the Commission which may at any time permit
the sale of the Restricted Securities to the public without registration, after
such time as a public market exists for the Common Stock of the Company, the
Company agrees to use its best efforts to:

                  (a) Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date that the Company becomes subject to the reporting
requirements of the Securities Act or the Securities Exchange Act of 1934, as
amended.

                  (b) File with the Commission in a timely manner all reports
and other documents required of the Company under the Securities Act and the
Securities Exchange Act of 1934, as amended (at any time after it has become
subject to such reporting requirements);

                  (c) So long as a Purchaser owns any Restricted Securities to
furnish to the Purchaser forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144
(at any time after 90 days after the effective date of the first registration
statement filed by the Company for an offering of its securities to the general
public), and of the Securities Act and the Securities Exchange Act of 1934 (at
any time after it has become subject to such reporting requirements), a copy of
the most recent annual or quarterly report of the Company, and such other


                                      -11-
<PAGE>   12
reports and documents of the Company and other information in the possession of
or reasonably obtainable by the Company as a Purchaser may reasonably request in
availing itself of any rule or regulation of the Commission allowing a Purchaser
to sell any such securities without registration.

         1.14 TRANSFER OF REGISTRATION RIGHTS. The rights to cause the Company
to register securities granted Purchasers under Sections 1.5, 1.6 and 1.7 may be
assigned (i) in connection with transactions involving the distribution without
consideration of Registrable Securities by any of the Purchasers to any of its
partners or retired partners or the estate of any of its partners or retired
partners, or (ii) to a transferee or assignee reasonably acceptable to the
Company in connection with any transfer or assignment of Registrable Securities
by a Purchaser, provided that (a) such transfer may otherwise be effected in
accordance with applicable securities laws, (b) such assignee or transferee
acquires at least 50,000 of the Registrable Securities and (c) the Company
receives reasonably prompt written notice of such transfer or assignment.

         1.15 STANDOFF AGREEMENT. Each Holder agrees in connection with the
Company's initial public offering of the Company's securities that, upon request
of the Company or the underwriters managing any underwritten offering of the
Company's securities, not to sell, make any short sale of, loan, grant any
option for the purchase of, or otherwise dispose of any Registrable Securities
(other than those included in the registration) without the prior written
consent of the Company or such underwriters, as the case may be, for such period
of time (not to exceed 180 days) from the effective date of such registration as
may be requested by the underwriters; provided, that the officers and directors
of the Company who own stock of the Company also agree to such restrictions with
respect to all of their shares.

         1.16 TERMINATION OF REGISTRATION RIGHTS. The registration rights
granted pursuant to Section 1 shall terminate as to each Holder at such time as
a public market for the Company's Common Stock exists and all Registrable
Securities held by such Holder may, in the opinion of counsel to the Company
(which opinion shall be concurred in by counsel for such Holder), be sold within
a given three month period pursuant to Rule 144 or any other applicable
exemption that allows for resale free of registration. The registration rights
granted pursuant to Section 1 shall terminate as to all Holders on the fifth
anniversary of the closing of the Company's initial public offering.
