and covenants with, the Investor as follows:

         4.1 Organization and Standing. The Company and each of its subsidiaries

under the laws of the jurisdiction of its incorporation with full corporate
power and corporate authority to own, lease and operate its properties and
conduct its current business as described in the Company's Annual Report on Form
10-K for the year ended December 31, 2000 (the "Form 10-K"); the Company is duly
qualified to do business as a foreign corporation and in good standing in each
jurisdiction in which the ownership or leasing of its properties or the conduct
of its business requires such qualification, except where the failure to be so
qualified or be in good standing is not reasonably likely to have a material
adverse effect on the condition (financial or otherwise), operations, business
or business prospects of the Company (hereinafter, a "Material Adverse Effect");
no proceeding has been instituted in any such jurisdiction revoking, limiting or
curtailing, or seeking to revoke, limit or curtail, such power and



<PAGE>


authority or qualification; the Company is in possession of and operating in
compliance with all material authorizations, licenses, certificates, consents,
orders and permits from federal, state and other regulatory authorities except
where the failure to possess or be in compliance with any of the foregoing is
not reasonably likely to have a Material Adverse Effect, all of which are valid
and in full force and effect. Other than the corporations, associations and
entities set forth on Exhibit 21 of the Form 10-K, the Company does not own or
control, directly or indirectly, any corporation, association or other entity.

         4.2 Corporate Power; Authorization. The Company has full legal right,
power and authority to enter into this Subscription Agreement and the Warrant
and to perform the transactions contemplated hereby and thereby. This
Subscription Agreement and the Warrant has been duly authorized, executed and
delivered by the Company and, assuming due authorization, execution and delivery
by each of the other parties hereto and thereto, are valid and binding
agreements on the part of the Company, enforceable in accordance with their
terms, except as may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws relating to or affecting
creditors' rights generally or by general equitable principles. The making,
execution and performance of this Subscription Agreement and the Warrant by the
Company and the consummation of the transactions herein and therein contemplated
will not conflict with or result in a breach or violation of any of the terms
and provisions of, or constitute a default under, (i) any bond, debenture, note
or other evidence of indebtedness, or under any 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 its properties may be
bound, (ii) the Certificate of Incorporation or Bylaws of the Company or (iii)
any law, order, rule, regulation, writ, injunction, judgment or decree of any
court, administrative agency, regulatory body, government or governmental agency
or body, domestic or foreign, having jurisdiction over the Company or its
properties, except (in any such case) for any conflict, breach, violation or
default which is not reasonably likely to have a Material Adverse Effect.

         4.3 Financial Statements. The Company has not distributed any offering
material in connection with the offering of the Shares other than the Form 10-K
and the Company's Quarterly Report on Form 10-Q for the quarter ended March 31,
2001 (the "Form 10-Q"). The Company has filed in a timely manner all documents
that the Company was required to file with the Securities and Exchange
Commission ("SEC") under Sections 13, 14(a) and 15(d) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), during the twelve (12) months
preceding the date of this Subscription Agreement (collectively, the "SEC
Filings"). As of their respective filing dates (or, if amended, when amended),
the SEC Filings complied with the requirements of the Exchange Act and were
complete and correct in all material respects. The Company satisfies the
registrant requirements for the use of Form S-3 under the Securities Act of
1933, as amended (the "Securities Act") in connection with secondary offerings
of its Common Stock by its stockholders. The consolidated financial statements
of the Company included in the Form 10-K and Form 10-Q (the "Financial
Statements") comply in all respects with applicable accounting requirements and
with the published rules and regulations of the SEC with respect thereto. The
Financial Statements have been prepared in accordance with generally accepted
accounting principles consistently applied ("GAAP") and fairly present the
financial position of the Company at the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal, recurring adjustments and the absence of
complete footnotes). Except as and to the extent reflected in the Financial
Statements, the Company did not have, as of the date of the Financial
Statements, any liabilities or obligations (other than obligations of continued
performance under contracts and other commitments and arrangements entered into
in the ordinary course of business) which GAAP would require the Company to
reflect in the Financial Statements. There



<PAGE>


have not been any changes in the assets, liabilities, financial condition or
operations of the Company from that reflected in the Financial Statements,
except changes in the ordinary course of business that have not had a Material
Adverse Effect.

         4.4 Capitalization. As of the date hereof, the authorized capital stock
of the Company consists of (i) 50,000,000 shares of Common Stock, of which
11,891,259 shares are issued and outstanding, 2,300,000 shares are reserved for
issuance under the Company's employee and director stock option plans, and
approximately 40,000 shares are reserved for issuance pursuant to securities
(other than securities issued under the foregoing plans) exercisable for, or
convertible into or exchangeable for shares of Common Stock; (ii) 20,000,000
shares of preferred stock, no par value, of which 3,500,000 shares are

duly authorized and validly issued and are fully paid and nonassessable, have
been issued in compliance with all applicable U.S. federal and state securities
laws, and were not issued in violation of or subject to any preemptive rights or
other rights to subscribe for or purchase securities. The Shares, and the shares
of Common Stock issuable upon the exercise of the Warrant (the "Warrant Shares")

Subscription Agreement, and, when issued and delivered by the Company against
payment therefor in accordance with the terms of this Subscription Agreement or
the Warrant, as applicable, will be duly and validly issued and fully paid and
nonassessable, and will be sold free and clear of any pledge, lien, security
interest, encumbrance, claim or equitable interest. The Company has duly and
validly reserved the Warrant Shares for issuance upon the exercise of the
Warrant. No preemptive right, co-sale right, registration right, right of first
refusal or other similar right of shareholders exists with respect to any of the
Shares or the Warrant Shares or the issuance and sale thereof other than those
that have been satisfied or expressly waived prior to the date hereof. No
further approval or authorization of any shareholder or the Board of Directors
of the Company is required for the issuance and sale or transfer of the Shares,
the Warrants or the Warrant Shares. Except as disclosed in the SEC Filings and
the Financial Statements, and the related notes thereto, the Company has no
outstanding options to purchase, or any preemptive rights or other rights to
subscribe for or to purchase, any securities or obligations convertible into, or
any contracts or commitments to issue or sell, shares of its capital stock or
any such options, rights, convertible securities or obligations.

12(g) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
and are approved for quotation on The Nasdaq National Market (the "NNM"). 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
delisting the Common Stock from the NNM.

         4.6 No Change. Subsequent to the date of filing of the Form 10-Q, there
has not been, except as set forth on the Form 10-Q (i) any material adverse

         4.7 No Defaults. The Company is not (i) in violation of its Certificate
of Incorporation or bylaws, (ii) in default (upon notice or lapse of time or
both) in the performance or observance of any obligation, agreement, covenant or
condition contained in any bond, debenture, note or other evidence of
indebtedness, or in any lease, contract, indenture, mortgage, deed of trust,
loan agreement, joint venture or other agreement or instrument to which it is a
party or by which its properties may be bound, or (iii) in violation of any law,
order, rule, regulation, writ, injunction, judgment or decree of any court,
government or governmental agency or body, domestic or foreign, having
jurisdiction over the Company or its properties except in the case of (ii) or
(iii) for any default or violation not reasonably likely to have a Material
Adverse Effect.

         4.8 Governmental Consents. No consent, approval, order or authorization
of, or registration, qualification, designation, declaration or filing with, any
federal, state or local governmental authority on the part of the Company is

this Subscription Agreement ("Consents") except for (i) such Consents which are
not material, (ii) compliance with the securities and Blue Sky laws in the
states and other jurisdictions in which Shares are offered and/or sold, which

applicable laws, rules and regulations of the jurisdictions in which it is
conducting business, including but not limited to, all applicable federal, state
and local environmental laws and regulations, except for any failure to comply

Investment Company Act of 1940, as amended (the "1940 Act"), and the rules and
regulations thereunder, and is not, and intends in the future to conduct its and
its subsidiaries' affairs in such a manner as to ensure that it is not and will
not become, an "investment company" or a company "controlled" by an "investment
company" within the meaning of the 1940 Act and such rules and regulations.

         Litigation. There is no claim, action, proceeding or investigation
pending, or to the knowledge of the Company, threatened against or relating to
the Company before any court or governmental or regulatory authority or body,
domestic or foreign, with respect to which there is a substantial possibility of
determination that would have a Material Adverse Effect on the Company, taken as
a whole, or prevent or delay any transaction contemplated by this Agreement, and
the Company is not subject to any outstanding order, writ, injunction or decree
that materially and adversely affects the Company, taken as a whole, or would
prevent or delay the transactions contemplated by this Agreement.

Registrable Share when (1) a Registration Statement covering a Registrable Share
has been declared effective by the SEC and such Share has been disposed of by
the Investor pursuant to such effective Registration Statement or such
Registration Statement has remained effective for 48 months from the date it was
first declared effective, (2) the Registrable Share is transferred to another
person (other than in connection with the transfer of the Warrant), (3) such
share (after initial issuance) is held by the Company or otherwise ceases to be
outstanding, or (4) such share may be traded without restriction pursuant to
Rule 144(k), if applicable; and (B) "Registration Statement" means any
registration statement or comparable document under the Securities Act through
which a public sale or disposition of the Registrable Shares may be registered,
including the prospectus, amendments and supplements to such registration
statement, all exhibits, and all material incorporated by reference or deemed to
be incorporated by reference in such registration statement.

         8.2 Suspension Of Effectiveness. The Company's obligations under
Section 8.1 above shall not restrict its ability to suspend the effectiveness
of, or direct the Investor not to offer or sell securities under, any
Registration Statement, at any time, for such reasonable period of time which
the Company reasonably believes is necessary to prevent the premature disclosure
of any events or information having a material effect on the Company; provided,
however, that the Company may not exercise such right for more than sixty (60)
days in any twelve-month period. In addition, the Company shall not be required
to keep any Registration Statement effective, or may, without suspending such
effectiveness, instruct the Investor not to sell such securities, during any
period during which the Company is instructed, directed, ordered or otherwise
requested by any governmental agency or self-regulatory organization to stop or
suspend such trading or sales. If the Company suspends the effectiveness of any
Registration Statement, the period specified in clause (1) in Section 8.1 shall
be extended for a period of time equal in length to the period of time during
which the Company suspended the effectiveness of the Registration Statement.

         8.3 Registration Procedures. Except as otherwise expressly provided
herein, in connection with any registration of Registrable Shares pursuant to
this Subscription Agreement, the Company shall, as expeditiously as possible:

                  (a) in accordance with the terms of Section 8.1, prepare and
file with the SEC a Registration Statement with respect to such Registrable
Shares and use its best efforts to cause such Registration Statement to become
effective as soon as practicable, and thereafter keep such Registration
Statement effective for the period specified in Section 8.1 above (as may be
extended in accordance with Section 8.2 above) or, if earlier, until the
distribution contemplated in the Registration Statement has been completed; and
before filing a Registration Statement or prospectus or any amendments or
supplements thereto, furnish to the Investor copies of such Registration
Statement and such other documents as proposed to be filed (including copies of
any document to be incorporated by reference therein), and thereafter furnish to
the Investor such number of copies as may be reasonably requested in writing by
the Investor of such Registration Statement, each amendment and supplement
thereto (including copies of any document to be incorporated by reference
therein), including all exhibits thereto, the prospectus included in such
Registration Statement (including each preliminary prospectus), and, promptly
after the effectiveness of a Registration Statement, the definitive final
prospectus filed with the SEC;

                  (b) notify the Investor, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
occurrence of any event as a result of which the prospectus included in such
Registration Statement (including any document to be incorporated



<PAGE>


by reference therein) contains an untrue statement of a material fact or omits
any fact necessary to make the statements therein not misleading and, at the
request of the Investor, the Company shall prepare a supplement or amendment to
such prospectus so that, as thereafter delivered to the purchasers of such
Registrable Shares, 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 and promptly make
available to the Investor any such supplement or amendment;

                  (c) notify the Investor and the managing underwriters, if any,
promptly, and (if requested by any such Person) confirm such advice in writing,
(i) when the Registration Statement, 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, when the same has become
effective, (ii) of the issuance by the SEC of any stop order suspending the
effectiveness of a Registration Statement or of any order preventing or
suspending the use of any preliminary prospectus or the initiation of any
proceedings for that purpose and the Company shall promptly use its reasonable
best efforts to prevent the issuance of any stop order or to obtain its
withdrawal if such stop order should be issued and (iii) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of a Registration Statement or any of the
Registrable Shares for offer or sale in any jurisdiction, or the initiation or
threatening of any proceeding for such purpose.

         The Company may require the Investor to furnish to the Company such
information regarding themselves and the distribution of such Registrable Shares
as the Company may from time to time reasonably request in writing and such
other information as may be legally required in connection with such
registration. The Investor agrees, by the acquisition of Registrable Shares and
the acceptance of the benefits provided to it hereunder, to furnish promptly to
the Company all information required to be disclosed in order to make any
previously furnished information not materially misleading. The Investor
proposing to distribute their Registrable Shares through such underwriting shall
(together with the Company) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected by the Company for such
underwriting and shall provide to such underwriter or underwriters any opinions
and certificates, and any indemnification with respect to such Investor as
reasonably required by such underwriter or underwriters.

         The Investor agrees that upon receipt of any notice from the Company of
the happening of any event of the kind described herein requiring the cessation
of the distribution of a prospectus or the distribution of a supplemented or
amended prospectus, the Investor will forthwith discontinue disposition of
Registrable Shares pursuant to the Registration Statement covering such
Registrable Shares until the Investor's receipt of the copies of the
supplemented or amended prospectus contemplated by this Subscription Agreement,
or until it is advised in writing by the Company that the use of the prospectus
may be resumed, and, if so directed by the Company, the Investor will deliver to
the Company (at the Company's expense) all copies, other than permanent file
copies then in the Investor's possession, of the prospectus covering such
Registrable Shares current at the time of receipt of such notice.

         8.4 Registration Expenses. All expenses incident to the Company's
performance of or compliance with the registration of shares pursuant to this
Subscription Agreement, including, without limitation, all registration and
filing fees, fees and expenses of compliance with securities or blue sky laws
(including reasonable fees and disbursements of counsel of the Company and
counsel for the underwriters in connection with "blue sky" qualifications of the
Registrable Shares), fees and



<PAGE>


expenses associated with filings required to be made with the National
Association of Securities Dealers, Inc., and with listing on any national
securities exchange or exchanges in which listing may be sought, printing
expenses, messenger and delivery expenses, fees and expenses of one counsel for
all Investors participating in such registration (not to exceed $15,000), fees
and expenses of counsel for the Company and its independent certified public
accountants, securities acts liability insurance (if the Company elects to
obtain such insurance), the fees and expenses of any special experts retained by
the Company in connection with such registration, and fees and expenses of other
persons retained by the Company (all such expenses being herein called
"Registration Expenses") will be borne by the Company; provided that in no event
shall Registration Expenses payable by the Company include any (i) underwriting
discounts, commissions, or fees attributable to the sale of Registrable Shares,
or (ii) transfer taxes, if any, all of which shall be borne by the Investor.

         8.5 Indemnification.

                  (a) To the extent permitted by law, the Company will indemnify
and hold harmless the Investor, the partners or officers, directors and
stockholders of the Investor, legal counsel, the investment adviser and
accountants for the Investor, any underwriter (as defined in the Securities Act)
for such Investor and each person, if any, who controls such Investor or
underwriter within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages or liabilities (joint or several) to which
they may become subject under the Securities Act, the Exchange Act or any state
securities laws, insofar as such losses, claims, damages, or liabilities (or
actions in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"): (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein a material fact required to be stated therein,
or necessary to make the statements therein not misleading, or (iii) any
violation or alleged violation by the Company of the Securities Act, the
Exchange Act, any state securities laws or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any state securities laws; and the
Company will reimburse each such Investor, underwriter or controlling person for
any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the indemnity agreement contained in this subsection
8.5(a) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Company (which consent shall not be unreasonably withheld), nor shall the
Company be liable in any such case for any such loss, claim, damage, liability
or action to the extent that it arises out of or is based upon a Violation that
occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by any such Investor,
underwriter or controlling person; provided further, however, that the foregoing
indemnity agreement with respect to any preliminary prospectus shall not inure
to the benefit of any Investor or underwriter, or any person controlling such
Investor or underwriter, from whom the person asserting any such losses, claims,
damages or liabilities purchased shares in the offering, if a copy of the
prospectus (as then amended or supplemented if the Company shall have furnished
any amendments or supplements thereto) was not sent or given by or on behalf of
such Investor or underwriter to such person, if required by law so to have been
delivered, at or prior to the written confirmation of the sale of the shares to
such person, and if the prospectus (as so amended or supplemented) would have
cured the defect giving rise to such loss, claim, damage or liability.



<PAGE>


                  (b) To the extent permitted by law, the Investor will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the Registration Statement, each person, if any, who
controls the Company within the meaning of the Securities Act, legal counsel and
accountants for the Company, any underwriter, each other Investor selling Shares
in the Registration Statement and any controlling person of any such underwriter
or other Investor, against any losses, claims, damages or liabilities (joint or
several) to which any of the foregoing persons may become subject, under the
Securities Act, the Exchange Act or any state securities laws, insofar as such
losses, claims, damages or liabilities (or actions in respect thereto) arise out
of or are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Investor expressly for use in connection
with the Registration Statement; and each such Investor will reimburse any
person intended to be indemnified pursuant to this subsection 8.5(b), for any
legal or other expenses reasonably incurred by such person in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the indemnity agreement contained in this subsection
8.5(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Investor (which consent shall not be unreasonably withheld), provided
that in no event shall any indemnity under this subsection 8.5(b) exceed the
gross proceeds from the offering received by such Investor.

                  (c) Promptly after receipt by an indemnified party under this
Section 8.5 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 8.5, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties that may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
8.5, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 8.5.

                  (d) If the indemnification provided for in this Section 8.5 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
herein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, 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 that 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 statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the



<PAGE>


indemnified party and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission.

                  (e) The obligations of the Company and Investors under this
Section 8.5 shall survive the completion of any offering of Registrable
Securities in a Registration Statement under this Section 8, and otherwise.

         9. MISCELLANEOUS.

         9.1 Nomination of Directors. The Investor shall have the right to
recommend nominees for the election of directors to the Board of Directors of
the Company or its Nominating Committee, if such committee has been formed. The
Board of Directors or its Nominating Committee shall consider the
recommendations of the Investor when determining management's slate of nominees
for any annual or special meeting of the stockholders of the Company held for
the purpose of electing directors or when filling any vacancy. The determination
of such slate, however, shall be in the sole and absolute discretion of the
Board of Directors or any applicable committee.

         9.2 Notice of Private Placement. If at any time prior to the first
anniversary of this Agreement, the Company proposes to make a private placement
of its debt or equity securities, the Company shall notify the Investor as soon
as practicable prior to offering such debt or equity securities in a private
placement.

         9.3 Waivers and Amendments. Neither this Subscription Agreement nor any
provision hereof may be changed, waived, discharged, terminated, modified or
amended except upon the written consent of the Company and holders of at least a

amendments, upon the written consent of the Company.

         9.4 Headings. The headings of the various sections of this Subscription
Agreement have been inserted for convenience of reference only and shall not be
deemed to be part of this Subscription Agreement.

         9.5 Broker's Fee. The Company and the Investor (severally and not
jointly) hereby represent that there are no brokers or finders entitled to
compensation in connection with the sale of the Shares, and shall indemnify each
other for any such fees for which they are responsible.

         9.6 Severability. If any term or provision of this Agreement is held to
be invalid or unenforceable, the remaining portions of this Agreement shall
continue to be valid and will be performed, construed, and enforced to the
fullest extent permitted by law, and the invalid or unenforceable term shall be
deemed amended and limited in accordance with the intent of the parties as
determined from the face of the Agreement, to the extent necessary to permit the
maximum enforceability or validity of the term or provision.

         9.7 Notices. All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed effectively given: (a) upon
personal delivery to the party to be notified, (b) when sent by confirmed

it will refrain from disclosing any such information to any person other than to
any agent, attorneys, accountants, employees, officers and directors of Investor
who need to know such information in connection with Investors' purchase of the
Shares, and who agree to be bound by the confidentiality provisions of this
Subscription Agreement. In the event that Investor or its agents are required by
federal or state or other law, rule or regulation or any decision or order of
