the Shares.

        NOW THEREFORE, in consideration of the foregoing recitals and the terms

the failure to be so qualified would have a material adverse effect upon the
business or financial condition of the Company and no proceeding has been
instituted in any such jurisdiction, revoking, limiting or curtailing, or
seeking to revoke, limit or curtail, such power and authority or qualification.

               4.2 Due Authorization. The Company has all requisite corporate
power and authority to execute, deliver and perform its obligations under this
Agreement, and this Agreement has been duly authorized and validly executed and

securities laws or the public policy underlying such laws, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' and contracting
parties' rights generally and except as enforceability may be subject to general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

               4.3 Non-Contravention. The execution and delivery of this
Agreement, the issuance and sale of the Shares to be sold by the Company under
this Agreement, the fulfillment of the terms of this Agreement and the
consummation of the transactions contemplated thereby will not (A) conflict with

or the passage of time or both) under, (i) any material bond, debenture, note or
other evidence of indebtedness, or under any material lease, contract,
indenture, mortgage, deed of trust, loan agreement, joint venture or other
agreement or instrument to which the Company is a party or by which it or its
properties or assets are bound, (ii) the charter, by-laws or other
organizational documents of the Company, or (iii) any law, administrative

interest or restriction whatsoever upon any of the material properties or assets

agreement or condition contained in any material bond, debenture, note or any
other evidence of indebtedness or any material indenture, mortgage, deed of
trust or any other agreement or instrument to which the Company is a party or by
which any of it or its properties or assets are bound or to which any of the

Exchange Act of 1934, as amended (the "Exchange Act"), during the 12 months

limitation, all exhibits included or incorporated by reference therein) complied
in all material respects with the requirements of the Securities and Exchange
Commission (the "SEC") as of their respective filing dates, and the information
contained therein as of the date thereof did not contain an 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, except to the extent that information
contained in any such document has been revised or superseded by a later filed
"SEC Document", which shall mean any document filed

thereof.

charter, bylaws, or other organizational document, or in violation of any law,
administrative regulation, ordinance or order of any court or governmental
agency, arbitration panel or authority applicable to the Company, which
violation, individually or in the aggregate, would be reasonably likely to have
a material adverse effect on the business or financial condition of the Company
or (ii) in default (and there exists no condition which, with or without the
passage of time or giving of notice or both, would constitute a default) in any
material respect in the performance of any bond, debenture, note or any other
evidence of indebtedness in any indenture, mortgage, deed of trust or any other
material agreement or instrument to which the Company is a party or by which the
Company is bound or by which the properties or assets of the Company are bound,
which would be reasonably likely to have a material adverse effect upon the
business or financial condition of the Company.

               4.8 NASDAQ Listing. The Company's Common Stock is registered
pursuant to Section 12(g) of the Exchange Act and is listed, and currently
complies with the requirements for continued listing, on The Nasdaq Stock
Market, Inc. National Market (the "Nasdaq National Market"), and the Company has
taken no action designed to, or likely to have the effect of, terminating the
registration of the Common Stock under the Exchange Act or de-listing the Common

National Association of Securities Dealers, Inc. currently contemplating
terminating such listing.

               4.9 Listing of the Shares. The Company shall comply with all

requirements of Section 12 of 15(d) of the Securities and Exchange Act of 1934
for a period of at least 12 calendar months immediately preceding the filing of
the registration statement, the Company would meet the requirements for the use
of Form S-3 for the registration of the resale of the Shares by Caliper. The
Company will use its best efforts to meet the requirements for the use of Form
S-3 for the registration of the resale of the



                                        3
<PAGE>   4

Shares by Caliper. Once the Company has become eligible to use Form S-3, it will
use its best efforts to maintain S-3 status with the SEC during the Registration
Period (as defined in Section 6.1(c)).

               4.11 No Registration. Assuming the accuracy of the
representations and warranties made by, and compliance with the covenants of,
Caliper in Section 5 hereof, no registration of the Shares under the Securities
Act of 1933, as amended (the "Securities Act"), is required in connection with
the offer and sale of the Shares by the Company to Caliper as contemplated by
this Agreement.

               4.12 Form D. The Company agrees to file one or more Forms D with
respect to the Shares as required under Regulation D under the Securities Act to
claim the exemption provided by Rule 506 of Regulation D.

        5. Representations, Warranties and Covenants of Caliper.

               5.1 Accredited Investor. Caliper represents and warrants to, and
covenants with, the Company that: (i) Caliper is an "accredited investor" as
defined in Regulation D under the Securities Act and Caliper has the knowledge,
sophistication and experience necessary to make, and is qualified to make
decisions with respect to, investments in shares presenting an investment
decision like that involved in the purchase of the Shares, including investments
in securities issued by the Company and investments in comparable companies, and
has requested, received, reviewed and considered all information it deemed
relevant in making an informed decision to purchase the Shares; (ii) Caliper is
acquiring the Shares for its own account for investment only and with no present
intention of distributing any of such Shares or any arrangement or understanding
with any other persons regarding the distribution, sale or transfer of such
Shares; (iii) Caliper will not, directly or indirectly, offer, sell, pledge,
transfer or otherwise dispose of (or solicit any offers to buy, purchase or
otherwise acquire or take a pledge of) any Registrable Shares (as defined in
Section 6.1(a) hereof) except in compliance with the Securities Act, applicable
state securities laws and the respective rules and regulations promulgated
thereunder; (iv) Caliper (A) has had no position, office or other material
relationship within the past three years with the Company or its affiliates (B)
neither it, nor any group of which it is a member or to which it is related,
beneficially owns (including the right to acquire or vote) any securities of the
Company and (C) it has no direct or indirect affiliation or association with any
NASD member; (v) Caliper will notify the Company immediately of any change in
any of such information on Schedule 5.1 until such time as Caliper has sold all
of its Registrable Shares or until the Company is no longer required to keep the
Registration Statement effective; and (vi) Caliper has, in connection with its
decision to acquire the Shares, had access to the SEC Documents and has had a
reasonable opportunity to ask questions of and receive answers from a person or
persons acting on behalf of the Company concerning the offering of the Shares
and all such questions have answered to the full satisfaction of Caliper.
Caliper understands that its acquisition of the Shares has not been registered
under the Securities Act or registered or qualified under any state securities
law in reliance on specific exemptions therefrom, which exemptions may depend
upon, among other things, the bona fide nature of Caliper's investment intent as
expressed herein. Caliper further understands that the Shares are "restricted
securities" under applicable federal and state securities laws and that,
pursuant to these laws, Caliper must hold the Shares indefinitely unless they
are registered under the Securities Act, or an exemption from such registration
requirements is available. Caliper acknowledges that, except as specifically
provided for in this Agreement, the Company has no obligation to register or
qualify the Shares for resale. Caliper further acknowledges that if an exemption
from registration or qualification is



                                        4
<PAGE>   5

available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of Caliper's control, and
which the Company is under no obligation and may not be able to satisfy.

               5.2 No Foreign Offering. Caliper acknowledges, represents and
agrees that no action has been or will be taken in any jurisdiction outside the
United States by the Company that would permit an offering of the Shares, or
possession or distribution of offering materials in connection with the issue of
the Shares, in any jurisdiction outside the United States where action for that
purpose is required. If Caliper is located or domiciled outside the United
States it agrees to comply with all applicable laws and regulations in each
foreign jurisdiction in which it purchases, offers, sells or delivers Shares or
has in its possession or distributes any offering material, in all cases at its
own expense.

               5.3 Legends; Transfer.

                      (a) Legends. Until the Registrable Shares have been
registered on an effective registration statement, the certificate or
certificates representing the Registrable Shares shall bear legends in
substantially the following form (as well as any legends required by applicable
state and federal corporate and securities laws):

                      THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR
INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN
EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A
FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER
THE SECURITIES ACT OF 1933.

                      (b) Stop-Transfer Notices. Caliper agrees that, in order
to ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

                      (c) Refusal to Transfer. The Company shall not be required
(i) to transfer on its books any Registrable Shares that have been sold or
otherwise transferred in violation of any of the provisions of this Agreement or
(ii) to treat as owner of such Registrable Shares or to accord the right to vote
or pay dividends to any purchaser or other transferee to whom such Registrable
Shares shall have been so transferred.

                      (d) All Transfers of the Registrable Shares to be Effected
Via Deutsche Banc Alex. Brown. In order to ensure timely and prompt compliance
by the parties hereto with the provisions of this Agreement, including without
limitation, the provisions of Section 7 hereof, the parties hereto agree that
all transfers and sales of any of the Registrable Shares by Caliper shall be
effected through the brokerage services department of Deutsche Banc Alex. Brown
(or such other broker as may be designated from time to time by the Company).

               5.4 Power and Authority. Caliper further represents and warrants
to the Company that (i) Caliper has full right, power, authority and capacity to
enter into this Agreement



                                        5
<PAGE>   6

and to consummate the transactions contemplated hereby and has taken all
necessary action to authorize the execution, delivery and performance of this
Agreement and (ii) this Agreement constitutes a valid and binding obligation of
Caliper enforceable against Caliper in accordance with its terms, except as
rights to indemnity and contribution may be limited by state or federal
securities laws or the public policy underlying such laws, and except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' and contracting
parties' rights generally and except as enforceability may be subject to general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

               5.5 Taxes. Caliper understands that nothing in this Agreement or
any other materials presented to Caliper in connection with the purchase and
sale of the Shares constitutes legal, tax or investment advice. Caliper has
consulted such legal, tax and investment advisors as it, in its sole discretion,
has deemed necessary or appropriate in connection with its purchase of Shares.
Caliper further agrees that it will be solely responsible for the withholding
and/or payment of any federal, state, or local taxes with respect to the Shares
issued to it hereunder, and it will indemnify and hold the Company harmless from
all liability related to the tax treatment of the Shares.

               5.6 Agreement to Vote Shares. In all stockholder actions and for
so long as Caliper holds any of the Registrable Shares, Caliper agrees to vote
the Registrable Shares in the manner recommended by the Company's Board of
Directors, except to the extent prohibited by applicable law.

        6. Registration of the Shares; Compliance with the Securities Act.

               6.1 Registration Procedures and Expenses. The Company shall:

                      (a) subject to receipt of necessary information from
Caliper, prepare and file with the SEC, within 60 days after the Closing Date, a
registration statement (the "Registration Statement") on Form S-3 (or if Company
does not qualify for Form S-3 on March 31, 2001, on Form S-1 or Form S-2) to
enable the resale of the Registrable Shares (as defined below) by Caliper on a
delayed or continuous basis under Rule 415 of the Securities Act. "Registrable
Shares" means (i) the Shares and (ii) any shares of capital stock issued or
issuable, from time to time, upon any reclassification, share combination, share
subdivision, stock split, share dividend, merger, consolidation or similar
transaction or event or otherwise as a distribution on, in exchange for, in
replacement of, or with respect to any of the foregoing, in each case held at
the relevant time by Caliper;

                      (b) use its best efforts, subject to receipt of necessary
information from Caliper, to cause the Registration Statement to become
effective within 90 days after the Closing Date;

                      (c) prepare and file with the SEC such amendments and
supplements to the Registration Statement and the Prospectus used in connection
therewith and take all such other actions as may be necessary to keep the
Registration Statement current and effective for a period (the "Registration
Period") commencing on the effective date of the Registration Statement and
ending on the earlier of (i) the second anniversary of the effective date of the
Registration Statement, (ii) the date on which Caliper may sell all Registrable
Shares then held by Caliper under Rule 144(k) of the Securities Act, and (iii)

                                        6

pursuant to a registration statement, (B) to or through a broker or dealer or
underwriter in a public distribution or a public securities transaction, and/or
(C) in a transaction exempt from the registration and prospectus delivery
requirements of the Securities Act under Section 4(1) thereof so that all
transfer restrictions and restrictive legends with respect thereto, if any, are

may reasonably request, in order to facilitate the public sale or other
disposition of all or any of the Registrable Shares by Caliper; provided
however, that the obligation of the Company to deliver copies of Prospectuses or
Preliminary Prospectuses to Caliper shall be subject to receipt by the Company
of reasonable assurances from Caliper that Caliper will comply with the
applicable provisions of the Securities Act and of such other securities or blue
sky laws as may be applicable in connection with any use of such Prospectuses or
Preliminary Prospectuses;

                      (e) take such action as may be necessary to register,
qualify or obtain an exemption for the Registrable Shares under such of the
state securities laws of United States jurisdictions as shall be necessary to
qualify, or obtain an exemption for, the sale of the Registrable Shares in
states specified in writing by Caliper; provided, however, that the Company
shall not be required to qualify to do business or consent to service of process
in any jurisdiction in which it is not now so qualified or has not so consented;

                      (f) advise Caliper promptly, (i) after it shall receive
notice or obtain knowledge of the issuance of any stop order by the SEC delaying
or suspending the effectiveness of the Registration Statement or of the
initiation or threat of any proceeding for that purpose, and it will promptly
use its commercially reasonable efforts to prevent the issuance of any stop
order to obtain its withdrawal at the earliest possible moment if such stop
order should be issued or other order should be issued; (ii) when the Prospectus
or any Prospectus Supplement or post-effective amendment has been filed, and,
with respect to the Registration Statement or any post-effective amendment
thereto, when the same has become effective; and (iii) after the Company shall
receive notice or obtain knowledge of the existence of any fact or the happening
of any event that makes any statement of a material fact made in the

any document incorporated by reference therein untrue, or that requires the
making of any additions to or changes in the Registration Statement or the
Prospectus in order to make the statements therein not misleading;

"Disposition") the Registrable Shares or its right to purchase the Registrable
Shares that would constitute a sale within the meaning of the Securities Act
except as contemplated in the Registration Statement referred to in Section 6.1
and as described below or otherwise in accordance with the Securities Act, and

distribution.

                      (b) Except in the event that paragraph (c) below applies,
the Company shall, (i) if deemed necessary by the Company, prepare and file from
time to time with the SEC a post-effective amendment to the Registration
Statement or a supplement to the related Prospectus or a supplement or amendment
to any document incorporated therein by reference or file any other required
document so that such Registration Statement will not contain an 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, and
so that, as thereafter delivered to purchasers of the Registrable Shares being
sold thereunder, such Prospectus will not contain an 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 Caliper copies of any
documents filed pursuant to Section 6.2(b)(i); and (iii) inform Caliper that the

of such post-effective amendment as promptly as possible and will promptly
notify Caliper pursuant to Section 6.2(b)(i) hereof when the amendment has
become effective).

any request by the SEC or any other federal or state governmental authority
during the period of effectiveness of the Registration Statement for amendments
or supplements to a Registration Statement or related Prospectus or for
additional information; (ii) of the issuance by the SEC or any other federal or
state governmental authority of any stop order suspending the effectiveness of a
Registration Statement or the initiation of any proceedings for that purpose;
(iii) of the receipt by the Company of any notification with respect to the
suspension of the qualification or exemption from qualification of any of the
Registrable Shares for sale in any jurisdiction or the initiation or threatening
of any proceeding for such purpose; or (iv) of any event or circumstance which
necessitates the making of any changes in the Registration Statement or
Prospectus, or any document incorporated or deemed to be incorporated therein by
reference, so that, in the case of the Registration Statement, it will not
contain any untrue statement of a material fact or any omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and that in the case of the Prospectus, it will not
contain any untrue statement of a material fact or any omission to state a
material fact required to be stated therein or necessary to make the statements

Section 6.2, Caliper shall not be prohibited from selling Registrable Shares
under the Registration Statement as a result of Suspensions on more than two
occasions of not more than 20 days each in any twelve month period, unless, in
the good faith judgment of the Company's Board of Directors, upon advice of
counsel, the sale of Registrable Shares under the Registration Statement in
reliance on this paragraph 6.2(d) would be reasonably likely to cause a
violation of the Securities Act or the Exchange Act and result in potential
liability to the Company.

                      (e) Provided that a Suspension is not then in effect,
Caliper may sell Registrable Shares under the Registration Statement, provided
that it arranges for delivery of a current Prospectus to the transferee of such
Shares.

                      (f) In the event of a sale of Registrable Shares by
Caliper under the Registration Statement, Caliper shall deliver to the Company's
transfer agent, with a copy to the Company, a Certificate of Subsequent Sale
substantially in the form attached hereto as Exhibit A, so that the Registrable
Shares may be properly transferred.

              6.3 Indemnification.

                      (a) For the purpose of this Section 6.3:

                           (i) the term "Registration Statement" shall include
any final Prospectus, exhibit, supplement or amendment included in or relating
to the Registration Statement referred to in Section 6.1; and

                           (ii) the term "untrue statement" shall include any
untrue statement or alleged untrue statement, or any omission or alleged
omission to state in the Registration Statement or Prospectus a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading.

                      (b) The Company agrees to indemnify and hold harmless
Caliper, the officers, directors and any underwriter (as defined in the
Securities Act) of Caliper, and each person, if any, who controls Caliper or
such underwriter within the meaning of the Securities Act or the Exchange Act,
from and against any losses, claims, damages or liabilities to which Caliper may
become subject (under the Securities Act or otherwise) insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of, or are based upon (i) any untrue statement of a material fact
contained in the Registration Statement, or (ii) any failure by the Company to
fulfill any undertaking included in the Registration Statement, or (iii) any
violation or alleged violation by the Company of the Securities Act, the
Exchange Act or any rule or regulation promulgated under the Securities Act or
the Exchange Act, and the Company will reimburse Caliper for any reasonable
legal or other expenses reasonably incurred in investigating, defending or
preparing to defend any such action, proceeding or claim, or preparing to defend
any such action, proceeding or claim, provided, however, that the Company shall
not be liable in any such case to the extent that such loss, claim, damage or
liability arises out of, or is based upon, an untrue statement made in such
Registration Statement in reliance upon and in conformity with written
information



                                        9
<PAGE>   10

furnished to the Company by or on behalf of Caliper specifically for use in
preparation of the Registration Statement or the failure of Caliper to comply
with its covenants and agreements contained in Sections 5.3 or 6.2 hereof
respecting sale of the Registrable Shares or any statement or omission in any
Prospectus that is corrected in any subsequent Prospectus that was delivered to
Caliper prior to the pertinent sale or sales by Caliper.

                      (c) Caliper agrees to indemnify and hold harmless the
Company, the officers and directors of the Company, and each person, if any, who
controls the Company within the meaning of the Securities Act or the Exchange
Act from and against any losses, claims, damages or liabilities to which the
Company (or any such officer, director or controlling person) may become subject
(under the Securities Act or otherwise), insofar as such losses, claims, damages
or liabilities (or actions or proceedings in respect thereof) arise out of, or
are based upon, (i) any failure to comply with the covenants and agreements
contained in Section 5.3 or 6.2 hereof respecting sale of the Shares, or (ii)
any untrue statement of a material fact contained in the Registration Statement
if such untrue statement was made in reliance upon and in conformity with
written information furnished by or on behalf of Caliper specifically for use in
preparation of the Registration Statement, and Caliper will reimburse the
Company (or such officer, director or controlling person), as the case may be,
for any legal or other expenses reasonably incurred in investigating, defending
or preparing to defend any such action, proceeding or claim. Notwithstanding the
foregoing, Caliper's liability pursuant to this subsection (b) shall be limited
to the net amount received by Caliper from the sale of the Shares, unless such
liability resulted from gross negligence or willful misconduct by Caliper.

                      (d) Promptly after receipt by any indemnified person of a
notice of a claim or the beginning of any action in respect of which indemnity
is to be sought against an indemnifying person pursuant to this Section 6.3,
such indemnified person shall notify the indemnifying person in writing of such
claim or of the commencement of such action, but the omission to so notify the
indemnifying party will not relieve it from any liability which it may have to
any indemnified party under this Section 6.3 (except to the extent that such
omission materially and adversely affects the indemnifying party's ability to
defend such action) or from any liability otherwise than under this Section 6.3.
Subject to the provisions hereinafter stated, in case any such action shall be
brought against an indemnified person, the indemnifying person shall be entitled
to participate therein, and, to the extent that it shall elect by written notice
delivered to the indemnified party promptly after receiving the aforesaid notice
from such indemnified party, shall be entitled to assume the defense thereof,
with counsel reasonably satisfactory to such indemnified person. After notice
from the indemnifying person to such indemnified person of its election to
assume the defense thereof, such indemnifying person shall not be liable to such
indemnified person for any legal expenses subsequently incurred by such
indemnified person in connection with the defense thereof, provided, however,
that if there exists or shall exist a conflict of interest that would make it
inappropriate, in the opinion of counsel to the indemnified person, for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof, the indemnified person shall be entitled to
retain its own counsel at the expense of such indemnifying person; provided,
however, that no indemnifying person shall be responsible for the fees and
expenses of more than one separate counsel (together with appropriate local
counsel) for all indemnified parties. In no event shall any indemnifying person
be liable in respect of any amounts paid in settlement of any action unless the
indemnifying person shall have approved the terms of such settlement; provided
that such consent shall not be unreasonably withheld. No indemnifying person
shall, without the prior written consent of the indemnified person, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified person is or could have been a party and indemnification could have
been sought hereunder by such indemnified person,



                                       10
<PAGE>   11

unless such settlement includes an unconditional release of such indemnified
person from all liability on claims that are the subject matter of such
proceeding.

                      (e) If the indemnification provided for in this Section
6.3 is unavailable to or insufficient to hold harmless an indemnified party
under subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the Company on the one hand and Caliper on the
other in connection with the statements or omissions or other matters which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
fault shall be determined by reference to, among other things, in the case of an
untrue statement, whether the untrue statement relates to information supplied
by the Company on the one hand or Caliper on the other and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such untrue statement. The Company and Caliper agree that it would not be just
and equitable if contribution pursuant to this subsection (d) were determined by
pro rata allocation (even if Caliper were treated as one entity for such
purpose) or by any other method of allocation which does not take into account
the equitable considerations referred to above in this subsection (d). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (d), Caliper shall not be required to contribute any amount in excess
of the net amount received by Caliper from the sale of the Shares. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.

                      (f) The parties to this Agreement hereby acknowledge that
they are sophisticated business persons who were represented by counsel during
the negotiations regarding the provisions hereof including, without limitation,
the provisions of this Section 6.3, and are fully informed regarding said
provisions.

                      They further acknowledge that the provisions of this
Section 6.3 fairly allocate the risks in light of the ability of the parties to
investigate the Company and its business in order to assure that adequate
disclosure is made in the Registration Statement as required by the Act and the
Exchange Act. The parties are advised that federal or state public policy as
interpreted by the courts in certain jurisdictions may be contrary to certain of
the provisions of this Section 6.3, and the parties hereto hereby expressly
waive and relinquish any right or ability to assert such public policy as a
defense to a claim under this Section 6.3 and further agree not to attempt to
assert any such defense.

               6.5 Termination of Conditions and Obligations. The conditions
precedent imposed by Section 5 or this Section 6 upon Dispositions of the
Registrable Shares by Caliper shall cease and terminate as to any particular
number of the Registrable Shares when such Registrable Shares shall have been
effectively registered under the Securities Act and sold or otherwise disposed
of in accordance with the intended method of disposition set forth in the
Registration Statement covering such Registrable Shares or at such time as an
opinion of counsel reasonably satisfactory to the Company shall have been
rendered to the effect that such conditions are not necessary in order to



                                       11
<PAGE>   12

comply with the Securities Act (provided that such opinion shall not be required
if the Company shall be furnished with written documentation reasonably
satisfactory to it that such Registrable Shares are being transferred in a
customary transaction exempt from registration under Rule 144 under the
Securities Act).

        7. Certain Dispositions of the Registrable Shares Following 18-Month
Anniversary.

               7.1 Definitions. For purposes of this Section 7, the following

trading day prior to such date, as reported in The Wall Street Journal;

                           (ii) If the Common Stock is quoted on the Nasdaq

                           (iii) In the absence of an established market for the
Common Stock, the Fair Market Value shall be determined by a
nationally-recognized investment banking firm chosen by the Board of Directors
of the Company, subject to the approval of Caliper (which approval shall not be
unreasonably withheld).

                      (d) "Holding Period" shall mean the period beginning on

                      (e) "Minimum Price" shall mean $36.11, as adjusted for any

occurring after the date hereof.



                                       12
<PAGE>   13

                      (f) "Threshold Number" for any day means 15% of the

Street Journal for the twenty (20) trading days preceding such day.

                      (g) "Uncovered Shares" means, on any date, Registrable
Shares with respect to which the Company's obligation to pay the Difference
pursuant to Section 7.2 has been deemed satisfied under and pursuant to the
provisions of Section 7.3(a).

               7.2 Certain Dispositions. Subject to Section 7.3:

                      (a) If, at any time after August 21, 2002 but before
February 21, 2003 Caliper provides notice (the "Notice of Disposition") to the
Company that Caliper desires to effect a Disposition of Covered Shares (which
Notice of Disposition shall include the date of the proposed disposition (the
"Proposed Disposition Date"), the number of Covered Shares proposed to be
disposed of and shall be delivered to the Company no less than ten (10) Business
Days before the Proposed Disposition Date), the Company may elect to repurchase
such Covered Shares by providing notice of such election to Caliper within five
(5) Business Days from receipt of the Notice of Disposition.

                      (b) If Company elects to repurchase such Covered Shares,
on the Proposed Disposition Date, Caliper shall deliver such Covered Shares to
the Company upon receipt from the Company, by wire transfer of immediately
available funds, of an amount equal to (i) the Fair Market Value on the Proposed
Disposition Date multiplied by the number of Covered Shares repurchased plus
(ii) the positive difference, if any, between the Minimum Price and Fair Market
Value on the Proposed Disposition Date multiplied by the number of Covered
Shares repurchased.

                      (c) If Company does not elect to repurchase such Covered
Shares, Company shall, within four (4) Business Days of receipt of notice from
Caliper of the Disposition of all or some of such Covered Shares by Caliper, pay
to Caliper, by wire transfer of immediately available funds, an amount equal to
the positive difference, if any, between the Minimum Price multiplied by the
number of Covered Shares sold by Caliper, and the net amount actually received
by Caliper from such Disposition (after deduction of applicable brokerage
commissions and fees). The notice shall include the number of Covered Shares
sold and the net amount actually received by Caliper from the sale of the
shares.

                      (d) If for any reason (including, without limitation,
because the sale of the Covered Shares is restricted under the Securities Act or
because there is no liquid market for the Covered Shares) any Covered Shares
included in the Notice of Disposition and not repurchased by the Company
pursuant to Section 7.2(b) remain unsold by Caliper thirty (30) days after the
date of the Notice of Disposition, Caliper shall so notify Company. Within four
(4) Business Days of receipt by Company of such notice, Company shall repurchase
such unsold Covered Shares by paying Caliper, by wire transfer of immediately
available funds, an amount equal to (i) the Fair Market Value on the day
preceding the date of such repurchase multiplied by the number of Covered Shares
repurchased, plus (ii) the positive difference, if any, between the Minimum
Price and such Fair Market Value multiplied by the number of Covered Shares
repurchased. Within four (4) Business Days of receipt of such amount from the
Company, Caliper shall deliver such repurchased Covered Shares to Company.



                                       13
<PAGE>   14

                      (e) Any amount paid by Company to Caliper under Section
7.2 (b)(ii), Section 7.2(c) or Section 7.2(d)(ii) shall be referred to as the
"Difference". The parties hereto agree that any payment of the Difference to
Caliper shall constitute part of the consideration for execution by Caliper of
this Agreement.

                      (f) With respect to the sale of Covered Shares on any
given trading day, Caliper covenants and agrees to instruct the broker handling
the Disposition (the "Broker") to sell, on any given trading day, a number of
Covered Shares that does not exceed the Threshold Number, calculated as of the
date of the Notice of Disposition.

                      (g) Notwithstanding anything in this Agreement to the
contrary, if at any time prior to February 21, 2003, the Company's shareholders
receive cash or securities in connection with a tender offer, recapitalization
transaction, merger or other business combination, then

               (i) if 95% or more of the market value of the consideration
        received by the Company's shareholders is cash, then the Company shall,
        within four (4) Business Days of receipt of notice from Caliper of the
        surrender by Caliper in such transaction of Covered Shares, pay to
        Caliper, by wire transfer of immediately available funds, an amount
        equal to the positive difference, if any, between the (x) Minimum Price
        multiplied by the number of Covered Shares surrendered by Caliper in
        such transaction, and (y) the sum of the net amount of cash plus the
        market value of any other consideration actually received by Caliper in
        such transaction; and

               (ii) if the consideration received by the Company's shareholders
        is not all cash, then the securities received by Caliper in such
        transaction shall be subject to the provisions of this Section 7 and
        shall be substituted in lieu of the Common Stock in all portions of this
        Section 7 and the Minimum Price shall be reduced by the amount of cash
        per share of Common Stock received by Caliper, and after such reduction,
        the Minimum Price shall be adjusted to give effect to such transaction.

               7.3 Limits on Company's Obligation to Pay Caliper.

                      (a) Notwithstanding anything to the contrary in Section
7.2, if on any trading day during the Holding Period (other than a day when
there is no Registration Statement in effect with respect to the Registrable
Shares (including, without limitation, during a Suspension) or the Company's
Common Stock is not listed on an established stock exchange or a national market
system), the average of the Fair Market Value of the Common Stock as determined
pursuant to Section 7.1(c)(i) on each of the five (5) market trading days prior
to such date is equal to or greater than the Minimum Price, then for each
consecutive trading day following such date on which the Fair Market Value is
equal to or greater than the Minimum Price, if Caliper does not sell the
Threshold Number of Registrable Shares for such day, then the Company's
obligation to pay the Difference pursuant to Section 7.2 shall be deemed
satisfied with respect to a number of Registrable Shares equal to the Threshold
Number for such day less the number of Registrable Shares actually sold on such
day; provided, however that if, on any day upon which Caliper would otherwise be
required to sell shares pursuant to this Section 7.3(a), Caliper instructs the
Broker to sell the Threshold Number of Registrable Shares for such day at or
above the Minimum Price (net of applicable brokerage commissions) and the Broker
fails to sell all of such Threshold Number of Registrable Shares at a price at
or above the Minimum Price (net of applicable brokerage commissions and fees),
the Company's obligation to pay the Difference shall not be deemed



                                       14
<PAGE>   15

satisfied with respect to such number of Registrable Shares that the Broker was
unable to sell at or above the Minimum Price (net of applicable brokerage
commissions and fees).

                      (b) If at the time of the sale by Caliper of any
Registrable Shares, there are any Uncovered Shares, then such sale of
Registrable Shares shall be deemed to be a sale of Covered Shares.

                      (c) Examples.

                           (i) Example 1. If the Fair Market Value of the Common
Stock during the Holding Period is at or above $36.11 per share for 12
consecutive trading days, and the daily Threshold Number for each of trading
days 6 through 12 is equal to 60,000, then, if Caliper sells no Registrable
Shares during days 6 through 12, the Company's obligation to repurchase the
Registrable Shares or to pay the Difference pursuant to Section 7.2 hereof shall
lapse and be deemed satisfied with respect to 360,000 Registrable Shares.
Assuming that Caliper sold no Registrable Shares during the Holding Period, at
the end of the Holding Period, Caliper would own 900,000 Registrable Shares, of
which 360,000 would be Uncovered Shares and 540,000 would be Covered Shares.

                           (ii) Example 2. If, in the case of Example 1 above,
Caliper further elects to sell 65,000 shares on Day 7, then under Section 7.3(a)
the Company's obligation to repurchase the Registrable Shares or to pay the
Difference pursuant to Section 7.2 hereof shall lapse and be deemed satisfied
with respect to 300,000 Registrable Shares. Assuming that Caliper sold no other
Registrable Shares during the Holding Period, at the end of the Holding Period,
Caliper would own 835,000 Registrable Shares, of which 300,000 would be
Uncovered Shares and 535,000 would be Covered Shares.

                           (iii) Example 3. If, in the case of Example 1 above,
Caliper further elects to sell 55,000 shares on Day 7, then under 7.3(a) the
Company's obligation to repurchase the Registrable Shares or to pay the
Difference pursuant to Section 7.2 hereof shall lapse and be deemed satisfied
with respect to 305,000 Registrable Shares. Assuming that Caliper sold no other
Registrable Shares during the Holding Period, at the end of the Holding Period,
Caliper would own 845,000 Registrable Shares, of which 305,000 would be
Uncovered Shares and 540,000 would be Covered Shares.

                           (iv) Example 4. If, in the case of Example 1 above,
Caliper further elects to sell 55,000 shares on Day 7, then under Section 7.3(a)
the Company's obligation to repurchase the Registrable Shares or to pay the
Difference pursuant to Section 7.2 hereof shall lapse and be deemed satisfied
with respect to 305,000 Registrable Shares. In addition, if the Fair Market
Value of the Common Stock was $35.00 on Day 13 and $37.00 on Day 14 and Caliper
elected to sell an additional 25,000 shares on Day 13, then at the end of the
Holding Period, Caliper would own 820,000 Registrable Shares, of which 305,000
would be Uncovered Shares and 515,000 would be Covered Shares.

               7.4 Except as to the limitations set forth in Sections 7.2(f) and
7.3 hereof, the Company shall have no obligation to pay the Difference for any
Disposition of Registrable Shares occurring prior to August 21, 2002 or after
February 21, 2003.

        8. Letter of Credit and Obligation of Caliper to Deliver Reduction
Certificates. A letter of credit, in the form attached hereto as Exhibit C,
shall be provided by Deutsche Bank (the "Bank")



                                       15

Credit"). The stated amount of the Letter of Credit shall initially be $32.5
million (the "Stated Amount"). The Stated Amount shall be subject to reduction
in accordance with the subsections of this Section 8.

               (a) Term. The Letter of Credit will terminate upon the earlier of
(i) the date upon which, as a result of the submission to the Bank by Caliper of
a Draw Certificate or a Reduction Certificate pursuant to the Letter of Credit,
the Stated Amount of the Letter of Credit is reduced to zero; and (ii) August
26, 2003.

               (b) Payment of Fees for Letter of Credit and Right of Offset. The
Company shall invoice Caliper on a quarterly basis for fifty percent (50%) of
all fees paid by the Company to Bank during such quarter pursuant to that
certain fee agreement between the Company and the Bank (the "Fee Agreement");
provided that (i) Caliper shall pay one hundred percent (100%) of all fees

a Disposition that does not require the Company to pay the Difference with
respect thereto; (w) five (5) Business Days after the payment by the Company of
the Difference in a Disposition that requires the Company to pay the Difference
with respect thereto; (x) five (5) Business Days after the repurchase of the
Registrable Shares and the payment of the Difference by the Company pursuant to
Section 7.2; (y) five (5) Business Days after the date that the Company's
obligations to pay the Difference has lapsed pursuant to Section 7.3 with
respect to all Registrable Shares; and (z) March 28, 2003; (ii) Caliper shall

Amount (as defined below) with respect to each L/C Reduction (as defined below)
to the extent that such fees accrue after the L/C Reduction Date for such L/C
Reduction; and (iii) for purposes of this provision (x) an "L/C Reduction" means
any reduction in the Stated Amount of the Letter of Credit which would result
from the delivery by Caliper to the Bank of a Reduction Certificate pursuant to
Section 8(c)(i)(D) or Section 8(c)(i)(E); (y) "L/C Reduction Amount" means, for
any L/C Reduction, the amount of the reduction in the Stated Amount of the
Letter of Credit which results from the delivery by Caliper to the Bank of the
Reduction Certificate with respect to such L/C Reduction; and (z) "L/C Reduction
Date" means, for any L/C Reduction, the date five (5) Business Days after the
Company has made the payments referred in Section 8(c)(i)(D) or Section
8(c)(i)(E), as applicable, with respect to such L/C Reduction. All such invoices
shall be accompanied by a copy of the invoice submitted to the Company by the
Bank for such quarter. Caliper shall pay all properly invoiced fees within five
(5) Business Days of receipt of such invoice. The Company covenants and agrees
that it shall not modify the Fee Agreement without the prior written consent of
Caliper, which consent shall not be unreasonably withheld.

Caliper Technologies Corp.

Mountain View, California 94043-2234

Ladies and Gentlemen:

        We have acted as special counsel to ACLARA BioSciences, Inc., a Delaware
corporation (the "Company"), in connection with the issuance of 900,000 shares
of the Company's common stock, par value $.001 per share (the "Shares"),
pursuant to the Common Stock Issuance Agreement by and between the Company and
Caliper Technologies Corp, a Delaware corporation, dated as of March ___, 2001
(the "Agreement"). Capitalized terms used herein and not otherwise defined
herein shall have the meanings given to them in the Agreement.

        As such counsel, we have examined such matters of fact and questions of
law as we have considered appropriate for purposes of this opinion. In our
examination, we have assumed the genuineness of all signatures (other than those
on behalf of the Company), the authenticity of all documents submitted to us as
originals, and the conformity to authentic original documents of all documents
submitted to us as copies. As to facts material to the opinions, statements and
assumptions expressed herein, we have, with your consent, relied upon oral or
written statements and representations of officers and other representatives of
the Company and others. In addition, we have obtained and relied upon such
certificates and assurances from public officials as we have deemed necessary.

        We are opining herein as to the effect on the subject transaction only
of the federal laws of the United States and the General Corporation Law of the
State of Delaware, and we express no opinion with respect to the applicability
thereto, or the effect thereon, of the laws of any other jurisdiction or, in the
case of Delaware, any other laws, or as to any matters of municipal law or the
laws of any local agencies within any state.

        Subject to the foregoing, it is our opinion, as of the date hereof, that
the Shares, upon issuance, delivery and payment therefor in the manner
contemplated by the Agreement, will be validly issued, fully paid and
nonassessable.

        This opinion is rendered only to you and is solely for your benefit in
connection with the transactions covered hereby. This opinion may not be relied
upon by you for any other purpose, without our prior written consent.

                                               Very truly yours,
