shares of Common Stock shall be allocated among the Holders pro-rata based on 
the total number of Registrable Securities issued or issuable as of each date 
that a Registration Statement, as amended, relating to the resale of the 
Registrable Securities is declared effective by the Commission.  
Notwithstanding anything herein contained to the contrary, if the actual 
number of shares of Common Stock into which the shares of Preferred Stock are 
convertible exceeds twice the number of shares of Common Stock into which the

exceeds the number of shares of Common Stock initially registered in 
accordance with the immediately prior sentence.  The Company shall have 15 
Business Days to file such additional Registration Statement after notice of 
the requirement thereof, which the Holders may give at such time when the 
number of shares of Common Stock as are issuable upon conversion of Preferred 
Stock exceeds 185% of the number of shares of Common Stock into which 
Preferred Stock are convertible, assuming such conversion occurred on the 
Closing Date or the Filing Date (whichever yields a lower Conversion Price.)

          "REGISTRATION STATEMENT" means the registration statements and any 
additional registration statements contemplated by Section 2(a), including 
(in each case) the Prospectus, amendments and supplements to such 
registration statement or Prospectus, including pre- and post-effective 
amendments, all exhibits thereto, and all material incorporated by reference 
in such registration statement.

     2.   SHELF REGISTRATION

          (a)  On or prior to each applicable Filing Date, the Company shall 
prepare and file with the Commission a "Shelf" Registration Statement 
covering all Registrable Securities for an offering to be made on a 
continuous basis pursuant to Rule 415.  The Registration Statement shall be 
on Form S-3 (except if otherwise directed by the Holders of a majority in 
interest of the applicable Registrable Securities in accordance herewith or 
if the Company is not then eligible to register for resale the Registrable 
Securities on Form S-3, in which case such registration shall be on another 
appropriate form in accordance herewith). The Registration Statement shall 
state, to the extent permitted by Rule 416 under the Securities Act, that it 
also covers such indeterminate number of shares of Common Stock as may be 
required to effect (i) conversion of the Preferred Stock to prevent dilution 
resulting from stock splits, stock dividends or similar events, or by reason 
of changes in the Conversion Price in accordance with the terms of the 
Certificate of Determination and (ii) exercise of the Warrants in full to 
prevent dilution resulting from stock splits, stock dividends or similar 
events, or by reason of changes in the Exercise Price (as defined in the 
Warrants) in accordance with the terms of the Warrants.  The Company shall 
(i) not permit any securities other than the Registrable Securities and those 
securities listed in Schedule 2.1(u) of the Disclosure Letter to be included 
in the Registration Statement and (ii) use its commercially reasonable 
efforts to cause the Registration Statement to be declared effective under 
the 


                                      -4-



Securities Act as promptly as possible after the filing thereof, but in any 
event prior to the Effectiveness Date, and to keep such Registration 
Statement continuously effective under the Securities Act until the date 
which is two years after the date that such Registration Statement is 
declared effective by the Commission or such earlier date when all 
Registrable Securities covered by such Registration Statement have been sold 
or may be sold without volume restrictions pursuant to Rule 144 as determined 
by the counsel to the Company pursuant to a written opinion letter, addressed 
to the Company's transfer agent to such effect (the "EFFECTIVENESS PERIOD").  
If an additional Registration Statement is required to be filed because the 
actual number of shares of Common Stock into which the Preferred Stock is 
convertible plus shares issuable upon payment of dividends and exercise of 
the Warrants exceeds the number of shares of Common Stock initially 
registered in respect of any particular series of Preferred Stock based upon 
the computation on a particular Closing Date, the Company shall, as promptly 
as reasonably possible, but no later than 20 Business Days to file such 
additional Registration Statement, and the Company shall use its best efforts 
to cause such additional Registration Statement to be declared effective by 
the Commission as soon as possible.

          (b)  If the Holders of a majority of the Registrable Securities so 
elect, an offering of Registrable Securities pursuant to the Registration 
Statement may be effected on no more than two occasions in the form of an 
Underwritten Offering.  In such event, and, if the managing underwriters 
advise the Company and such Holders in writing that in their opinion the 
amount of Registrable Securities proposed to be sold in such Underwritten 
Offering exceeds the amount of Registrable Securities which can be sold in 
such Underwritten Offering, the Registrable Securities of CIBC shall first be 
excluded from such Underwritten Offering and then if in the opinion of such 
managing underwriters the amount of Registrable Securities proposed to be 
sold in such Underwritten Offering still exceeds the amount of Registrable 
Securities which can be sold in such Underwritten Offering there shall be 
included in such Underwritten Offering the amount of such Registrable 
Securities which in the opinion of such managing underwriters can be sold, 
and such amount shall be allocated pro rata among the Holders (excluding 
CIBC) proposing to sell Registrable Securities in such Underwritten Offering. 

          (c)  If any of the Registrable Securities are to be sold in an 
Underwritten Offering, the investment banker in interest that will administer 
the offering will be selected by the Holders of a majority of the Registrable 
Securities included in such offering provided that the Company shall consent 
to the inclusion of such investment banker, which consent shall not be 
unreasonably withheld.  No Holder may participate in any Underwritten 
Offering hereunder unless such Holder (i) agrees to sell its Registrable 
Securities on the basis provided in any underwriting agreements approved by 
the Persons entitled hereunder to approve such arrangements and (ii) 
completes and executes all questionnaires, powers of attorney, indemnities, 
underwriting agreements and other documents required under the terms of such 
arrangements.

     3.   REGISTRATION PROCEDURES

          In connection with the Company's registration obligations 
hereunder, the Company shall:

          (a)  Prepare and file with the Commission on or prior to each 
applicable Filing Date, a Registration Statement on Form S-3 (or if the 
Company is not then eligible to register for resale the 


                                      -5-



Registrable Securities on Form S-3 such registration shall be on another 
appropriate form in accordance herewith, or, in connection with an 
Underwritten Offering hereunder, such other form agreed to by the Company and 
by a majority-in-interest of Holders of Registrable Securities) in accordance 
with the method or methods of distribution thereof as specified by the 
Holders (except if otherwise directed by the Holders), and cause the 
Registration Statement to become effective and remain effective as provided 
herein; PROVIDED, HOWEVER, that not less than five (5) Business Days prior to 
the filing of the Registration Statement or any related Prospectus or any 
amendment or supplement thereto (including any document that would be 
incorporated therein by reference), the Company shall, if reasonably 
practicable (i) furnish to the Holders, their Special Counsel and any 
managing underwriters, copies of all such documents proposed to be filed, 
which documents (other than those incorporated by reference) will be subject 
to the review of such Holders, their Special Counsel and such managing 
underwriters, and (ii) cause its officers and directors, counsel and 
independent certified public accountants to respond to such inquiries as 
shall be necessary, in the reasonable opinion of respective counsel to such 
Holders and such underwriters, to conduct a reasonable investigation within 
the meaning of the Securities Act. The Company shall not file the 
Registration Statement or any such Prospectus or any amendments or 
supplements thereto to which the Holders of a majority of the Registrable 
Securities, their Special Counsel, or any managing underwriters, shall 
reasonably object in writing within three (3) Business Days of their receipt 
thereof.

          (b)  (i)  Prepare and file with the Commission such amendments, 
including post-effective amendments, to the Registration Statement as may be 
necessary to keep the Registration Statement continuously effective as to the 
applicable Registrable Securities for the Effectiveness Period and prepare 
and file with the Commission such additional Registration Statements in order 
to register for resale under the Securities Act all of the Registrable 
Securities; (ii) cause the related Prospectus to be amended or supplemented 
by any required Prospectus supplement, and as so supplemented or amended to 
be filed pursuant to Rule 424 (or any similar provisions then in force) 
promulgated under the Securities Act; (iii) respond as promptly as reasonably 
possible to any comments received from the Commission with respect to the 
Registration Statement or any amendment thereto and as promptly as reasonably 
possible provide the Holders true and complete copies of all correspondence 
from and to the Commission relating to the Registration Statement; and (iv) 
comply in all material respects with the provisions of the Securities Act and 
the Exchange Act with respect to the disposition of all Registrable 
Securities covered by the Registration Statement during the applicable period 
in accordance with the intended methods of disposition by the Holders thereof 
set forth in the Registration Statement as so amended or in such Prospectus 
as so supplemented.

          (c)  Notify the Holders of Registrable Securities to be sold, their 
Special Counsel and any managing underwriters as promptly as reasonably 
possible (and, in the case of (i)(A) below, not less than five (5) days prior 
to such filing) and (if requested by any such Person) confirm such notice in 
writing no later than one (1) Business Day following the day (i)(A) when a 
Prospectus or any Prospectus supplement or post-effective amendment to the 
Registration Statement is proposed to be filed; (B) when the Commission 
notifies the Company whether there will be a "review" of such Registration 
Statement and whenever the Commission comments in writing on such 
Registration Statement and (C) with respect to the Registration Statement or 
any post-effective amendment, when the same has become effective; (ii) of any 
request by the Commission or any other Federal or state governmental 
authority for amendments or supplements to the Registration Statement or 
Prospectus or for additional information; (iii) of the 


                                      -6-



issuance by the Commission of any stop order suspending the effectiveness of 
the Registration Statement covering any or all of the Registrable Securities 
or the initiation of any Proceedings for that purpose; (iv) if at any time 
any of the representations and warranties of the Company contained in any 
agreement (including any underwriting agreement) contemplated hereby ceases 
to be true and correct in all material respects; (v) 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 
Securities for sale in any jurisdiction, or the initiation or threatening of 
any Proceeding for such purpose; and (vi) of the occurrence of any event that 
makes any statement made in the Registration Statement or Prospectus or any 
document incorporated or deemed to be incorporated therein by reference 
untrue in any material respect or that requires any revisions to the 
Registration Statement, Prospectus or other documents so that, in the case of 
the Registration Statement or the Prospectus, as the case may be, it will not 
contain any 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, in light of the circumstances under which they were made, not 
misleading.

          (d)  Use its best efforts to avoid the issuance of, or, if issued, 
obtain the withdrawal of (i) any order suspending the effectiveness of the 
Registration Statement or (ii) any suspension of the qualification (or 
exemption from qualification) of any of the Registrable Securities for sale 
in any jurisdiction, at the earliest practicable moment.

          (e)  If requested by any managing underwriter or the Holders of a 
majority in interest of the Registrable Securities to be sold in connection 
with an Underwritten Offering, (i) promptly incorporate in a Prospectus 
supplement or post-effective amendment to the Registration Statement such 
information as the Company reasonably agrees should be included therein and 
(ii) make all required filings of such Prospectus supplement or such 
post-effective amendment as soon as practicable after the Company has 
received notification of the matters to be incorporated in such Prospectus 
supplement or post-effective amendment; PROVIDED, HOWEVER, that the Company 
shall not be required to take any action pursuant to this Section 3(e) that 
would, in the opinion of counsel for the Company, violate applicable law or 
be materially detrimental to the business prospects of the Company.

          (f)  Furnish to each Holder, their Special Counsel and any managing 
underwriters, without charge, at least one conformed copy of each 
Registration Statement and each amendment thereto, including financial 
statements and schedules, all documents incorporated or deemed to be

by such Person (including those previously furnished or incorporated by 
reference) promptly after the filing of such documents with the Commission.

          (g)  Promptly deliver to each Holder, their Special Counsel, and 
any underwriters, without charge, as many copies of the Prospectus or 
Prospectuses (including each form of prospectus) and each amendment or 
supplement thereto as such Persons may reasonably request; and the Company 
hereby consents to the use of such Prospectus and each amendment or 
supplement thereto by each of the selling Holders and any underwriters in 
connection with the offering and sale of the Registrable Securities covered 
by such Prospectus and any amendment or supplement thereto.


                                      -7-



          (h)  Prior to any public offering of Registrable Securities, use 
its best efforts to register or qualify or cooperate with the selling 
Holders, any underwriters and their Special Counsel in connection with the 
registration or qualification (or exemption from such registration or 
qualification) of such Registrable Securities for offer and sale under the 
securities or Blue Sky laws of such jurisdictions within the United States as 
any Holder or underwriter requests in writing, to keep each such registration 
or qualification (or exemption therefrom) effective during the Effectiveness 
Period and to do any and all other acts or things necessary or advisable to 
enable the disposition in such jurisdictions of the Registrable Securities 
covered by a Registration Statement; PROVIDED, HOWEVER, that the Company 
shall not be required to qualify generally to do business in any jurisdiction 
where it is not then so qualified or to take any action that would subject it 
to general service of process in any such jurisdiction where it is not then 
so subject or subject the Company to any material tax in any such 
jurisdiction where it is not then so subject.

          (i)  Cooperate with the Holders and any managing underwriters to 
facilitate the timely preparation and delivery of certificates representing 
Registrable Securities to be delivered to a transferee pursuant to a 
Registration Statement, which certificates shall be free, to the extent 
permitted by applicable law, of all restrictive legends, and to enable such 
Registrable Securities to be in such denominations and registered in such 
names as any such managing underwriters or Holders may request at least two 
Business Days prior to any sale of Registrable Securities.

          (j)  Upon the occurrence of any event contemplated by Section 
3(c)(vi), as promptly as reasonably possible, prepare a supplement or 
amendment, including a post-effective amendment, to the Registration 
Statement or a supplement to the related Prospectus or any document 
incorporated or deemed to be incorporated therein by reference, and file any 
other required document so that, as thereafter delivered, neither the 
Registration Statement nor such Prospectus will 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.

          (k)  Use its best efforts to cause all Registrable Securities 
relating to such Registration Statement to be listed on the Nasdaq Stock 
Market and any other securities exchange, quotation system, market or 
over-the-counter bulletin board, if any, on which similar securities issued 
by the Company are then listed as and when required pursuant to the Purchase 
Agreement.

          (l)  Enter into such agreements (including an underwriting 
agreement in form, scope and substance as is customary in Underwritten 
Offerings) and take all such other actions in connection therewith (including 
those reasonably requested by any managing underwriters and the Holders of a 
majority of the Registrable Securities being sold) in order to expedite or 
facilitate the disposition of such Registrable Securities, and whether or not 
an underwriting agreement is entered into, (i) make such representations and 
warranties to such Holders and such underwriters as are customarily made by 
issuers to underwriters in underwritten public offerings, and confirm the 
same if and when requested; (ii) in the case of an Underwritten Offering 
obtain and deliver copies thereof to the managing underwriters, if any, of 
opinions of counsel to the Company and updates thereof addressed to each such 
underwriter, in form, scope and substance reasonably satisfactory to any such 
managing underwriters and Special Counsel to the selling Holders covering the 
matters customarily covered in opinions requested in Underwritten 


                                      -8-



Offerings and such other matters as may be reasonably requested by such 
Special Counsel and underwriters; (iii) immediately prior to the 
effectiveness of the Registration Statement, and, in the case of an 
Underwritten Offering, at the time of delivery of any Registrable Securities 
sold pursuant thereto, use its best reasonable efforts to obtain and deliver 
copies to the Holders and the managing underwriters, if any, of "cold 
comfort" letters and updates thereof from the independent certified public 
accountants of the Company (and, if necessary, any other independent 
certified public accountants of any subsidiary of the Company or of any 
business acquired by the Company for which financial statements and financial 
data is, or is required to be, included in the Registration Statement), 
addressed to the Company in form and substance as are customary in connection 
with Underwritten Offerings; (iv) if an underwriting agreement is entered 
into, the same shall contain indemnification provisions and procedures no 
less favorable to the selling Holders and the underwriters, if any, than 
those set forth in Section 6 (or such other provisions and procedures 
acceptable to the managing underwriters, if any, and holders of a majority of 
Registrable Securities participating in such Underwritten Offering); and (v) 
deliver such documents and certificates as may be reasonably requested by the 
Holders of a majority of the Registrable Securities being sold, their Special 
Counsel and any managing underwriters to evidence the continued validity of 
the representations and warranties made pursuant to clause 3(l)(i) above and 
to evidence compliance with any customary conditions contained in the 
underwriting agreement or other agreement entered into by the Company.

          (m)  Make available for inspection by the selling Holders, any 
representative of such Holders, any underwriter participating in any 
disposition of Registrable Securities, and any attorney or accountant 
retained by such selling Holders or underwriters, at the offices where 
normally kept, during reasonable business hours, all financial and other 
records, pertinent corporate documents and properties of the Company and its 
subsidiaries, and cause the officers, directors, agents and employees of the 
Company and its subsidiaries to supply all information in each case 
reasonably requested by any such Holder, representative, underwriter, 
attorney or accountant in connection with the Registration Statement; 
PROVIDED, HOWEVER, that any information that is determined in good faith by 
the Company in writing to be of a confidential nature at the time of delivery 
of such information shall be kept confidential by such Persons, unless (i) 
disclosure of such information is required by court or administrative order 
or is necessary to respond to inquiries of regulatory authorities; (ii) 
disclosure of such information, in the opinion of counsel to such Person, is 
required by law; (iii) such information becomes generally available to the 
public other than as a result of a disclosure or failure to safeguard by such 
Person; or (iv) such information becomes available to such Person from a 
source other than the Company and such source is not known by such Person to 
be bound by a confidentiality agreement with the Company.

          (n)  Comply in all material respects with all applicable rules and 
regulations of the Commission.

          (o)  The Company may require each selling Holder to furnish to the 
Company information regarding such Holder and the distribution of such 
Registrable Securities as is required by law to be disclosed in the 
Registration Statement, and the Company may exclude from such registration 
the Registrable Securities of any such Holder who unreasonably fails to 
furnish such information within a reasonable time after receiving such 
request.


                                      -9-



          If the Registration Statement refers to any Holder by name or 
otherwise as the holder of any securities of the Company, then such Holder 
shall have the right to require (if such reference to such Holder by name or 
otherwise is not required by the Securities Act or any similar Federal 
statute then in force) the deletion of the reference to such Holder in any 
amendment or supplement to the Registration Statement filed or prepared 
subsequent to the time that such reference ceases to be required.

          Each Holder covenants and agrees that (i) it will not sell any 
Registrable Securities under the Registration Statement until it has received 
copies of the Prospectus as then amended or supplemented as contemplated in 
Section 3(g) and notice from the Company that such Registration Statement and 
any post-effective amendments thereto have become effective as contemplated 
by Section 3(c) and (ii) it and its officers, directors or Affiliates, if 
any, will comply with the prospectus delivery requirements of the Securities 
Act as applicable to them in connection with sales of Registrable Securities 
pursuant to the Registration Statement.

          Each Holder agrees by its acquisition of such Registrable 
Securities that, upon receipt of a notice from the Company of the occurrence 
of any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 
3(c)(v) or 3(c)(vi), such Holder will forthwith discontinue disposition of 
such Registrable Securities under the Registration Statement until such 
Holder's receipt of the copies of the supplemented Prospectus and/or amended 
Registration Statement contemplated by Section 3(j), or until it is advised 
in writing (the "ADVICE") by the Company that the use of the applicable 
Prospectus may be resumed, and, in either case, has received copies of any 
additional or supplemental filings that are incorporated or deemed to be 
incorporated by reference in such Prospectus or Registration Statement.

          (p)  If (a) there is material non-public information regarding the 
Company which the Company's Board of Directors reasonably determines not to 
be in the Company's best interest to disclose and which the Company is not 
otherwise required to disclose, or (b) there is a significant business 
opportunity (including but not limited to the acquisition or disposition of 
assets (other than in the ordinary course of business) or any merger, 
consolidation, tender offer or other similar transaction) available to the 
Company which the Company's Board of Directors reasonably determines not to 
be in the Company's best interest to disclose, then the Company may postpone 
or suspend filing or effectiveness of a registration statement for a period 
not to exceed 20 consecutive days, provided that the Company may not postpone 
or suspend its obligation under this Section 3(p) for more than 60 days in 
the aggregate during any 12 month period; provided, however, that no such 
postponement or suspension shall be permitted for consecutive 20 day periods, 
arising out of the same set of facts, circumstances or transactions.

     4.   REGISTRATION EXPENSES

          (a)  All fees and expenses incident to the performance of or 
compliance with this Agreement by the Company, except as and to the extent 
specified in Section 4(b), shall be borne by the Company whether or not 
pursuant to an Underwritten Offering and whether or not the Registration 
Statement is filed or becomes effective and whether or not any Registrable 
Securities are sold pursuant to the Registration Statement.  The fees and 
expenses referred to in the foregoing sentence shall include, without 
limitation, (i) all registration and filing fees (including, without 
limitation, fees and expenses (A) 


                                      -10-



with respect to filings required to be made with the Nasdaq Stock Market and 
each other securities exchange or market on which Registrable Securities are 
required hereunder to be listed and (B) in compliance with state securities 
or Blue Sky laws (including, without limitation, fees and disbursements of 
counsel for the Holders in connection with Blue Sky qualifications or 
exemptions of the Registrable Securities and determination of the eligibility 
of the Registrable Securities for investment under the laws of such 
jurisdictions as the managing underwriters, if any, or the Holders of a 
majority of Registrable Securities may designate)), (ii) printing expenses 
(including, without limitation, expenses of printing certificates for 
Registrable Securities and of printing prospectuses if the printing of 
prospectuses is requested by the managing underwriters, if any, or by the 
holders of a majority of the Registrable Securities included in the 
Registration Statement), (iii) messenger, telephone and delivery expenses, 
(iv) fees and disbursements of counsel for the Company and Special Counsel 
for the Holders, in the case of the Special Counsel, to a maximum amount of 
$10,000, (v) Securities Act liability insurance, if the Company so desires 
such insurance, and (vi) fees and expenses of all other Persons retained by 
the Company in connection with the consummation of the transactions 
contemplated by this Agreement.  In addition, the Company shall be 
responsible for all of its internal expenses incurred in connection with the 
consummation of the transactions contemplated by this Agreement (including, 
without limitation, all salaries and expenses of its officers and employees 
performing legal or accounting duties), the expense of any annual audit, the 
fees and expenses incurred in connection with the listing of the Registrable 
Securities on any securities exchange as required hereunder.

          (b)  If the Holders require an Underwritten Offering pursuant to 
the terms hereof, the Company shall be responsible for all costs, fees and 
expenses in connection therewith, except for the fees and disbursements of 
the Underwriters (including any underwriting commissions and discounts) and 
their legal counsel and accountants (which shall be borne by the Holders).  
Therefore, in such circumstances, the Holder shall bear the expenses of the 
fees and disbursements of any legal counsel or accounting firm retained by 
the underwriters in connection with such Underwritten Offering and the costs 
of any determination (but not filing) by the underwriters of the eligibility 
of the Registrable Securities for investment under the applicable state 
securities laws.  By way of illustration which is not intended to diminish 
from the provisions of Section 4(a), the Holders shall not be responsible 
for, and the Company shall be required to pay the fees or disbursements 
incurred by the Company (including by its legal counsel and accountants) in 
connection with, the preparation and filing of a Registration Statement and 
related Prospectus for such offering, the maintenance of such Registration 
Statement in accordance with the terms hereof, the listing of the Registrable 
Securities in accordance with the requirements hereof, and printing expenses 
incurred to comply with the requirements hereof.

     5.   INDEMNIFICATION

          (a)  INDEMNIFICATION BY THE COMPANY.  The Company shall, 
notwithstanding any termination of this Agreement, indemnify and hold 
harmless each Holder, the officers, directors, agents (including any 
underwriters retained by such Holder in connection with the offer and sale of 
Registrable Securities), brokers (including brokers who offer and sell 
Registrable Securities as principal as a result of a pledge or any failure to 
perform under a margin call of Common Stock), investment advisors and 
employees of each of them, each Person who controls any such Holder (within 
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange 
Act) and the officers, directors, agents and 


                                      -11-



employees of each such controlling Person, to the fullest extent permitted by 
applicable law, from and against any and all losses, claims, damages, 
liabilities, costs (including, without limitation, costs of preparation and 
attorneys' fees) and expenses (collectively, "LOSSES"), as incurred, arising 
out of or relating to any untrue or alleged untrue statement of a material 
fact contained in the Registration Statement, any Prospectus or any form of 
prospectus or in any amendment or supplement thereto or in any preliminary 
prospectus, or arising out of or relating to any omission or alleged omission 
of a material fact required to be stated therein or necessary to make the 
statements therein (in the case of any Prospectus or form of prospectus or 
supplement thereto, in light of the circumstances under which they were made) 
not misleading (in the case of any Prospectus or form of Prospectus or 
supplement thereto, in light of the circumstances under which they were 
made), except to the extent, but only to the extent, that such untrue 
statements or omissions are based solely upon information regarding such 
Holder furnished in writing to the Company by such Holder expressly for use 
therein, which information was reasonably relied on by the Company for use 
therein or to the extent that such information relates to such Holder or such 
Holder's proposed method of distribution of Registrable Securities and was 
reviewed and expressly approved in writing by such Holder expressly for use 
in the Registration Statement, such Prospectus or such form of Prospectus or 
in any amendment or supplement thereto.  The Company shall notify the Holders 
promptly of the institution, threat or assertion of any Proceeding of which 
the Company is aware in connection with the transactions contemplated by this 
Agreement.

          (b)  INDEMNIFICATION BY HOLDERS.  Each Holder shall, severally and 
not jointly, indemnify and hold harmless the Company, the directors, 
officers, agents and employees, each Person who controls the Company (within 
the meaning of Section 15 of the Securities Act and Section 20 of the 
Exchange Act), and the directors, officers, agents or employees of such 
controlling Persons, to the fullest extent permitted by applicable law, from 
and against all Losses (as determined by a court of competent jurisdiction in 
a final judgment not subject to appeal or review) arising solely out of or 
based solely upon any untrue statement of a material fact contained in the 
Registration Statement, any Prospectus, or any form of prospectus, or in any 
amendment or supplement thereto, or arising solely out of or based solely 
upon any omission of a material fact required to be stated therein or 
necessary to make the statements therein not misleading to the extent, but 
only to the extent, that such untrue statement or omission is contained in 
any information so furnished in writing by such Holder to the Company 
specifically for inclusion therein the Registration Statement or such 
Prospectus and that such information was reasonably relied upon by the 
Company for use in the Registration Statement, such Prospectus or such form 
of prospectus or to the extent that such information relates to such Holder 
or such Holder's proposed method of distribution of Registrable Securities 
and was reviewed and expressly approved in writing by such Holder expressly 
for use in the Registration Statement, such Prospectus or such form of 
Prospectus, or in any amendment or supplement thereto.  In no event shall the 
liability of any selling Holder hereunder be greater in amount than the 
dollar amount of the net proceeds received by such Holder upon the sale of 
the Registrable Securities giving rise to such indemnification obligation; 
PROVIDED, HOWEVER, that no such limitation shall apply if such Losses result 
solely from the willful misconduct of such Holder.

          (c)  CONDUCT OF INDEMNIFICATION PROCEEDINGS. If any Proceeding 
shall be brought or asserted against any Person entitled to indemnity 
hereunder (an "INDEMNIFIED PARTY"), such Indemnified Party promptly shall 
notify the Person from whom indemnity is sought (the "INDEMNIFYING PARTY") in 
writing, and the Indemnifying Party shall assume the defense thereof, 
including the employment of 


                                      -12-



counsel reasonably satisfactory to the Indemnified Party and the payment of 
all fees and expenses incurred in connection with defense thereof; provided, 
that the failure of any Indemnified Party to give such notice shall not 
relieve the Indemnifying Party of its obligations or liabilities pursuant to 
this Agreement, except (and only) to the extent that it shall be finally 
determined by a court of competent jurisdiction (which determination is not 
subject to appeal or further review) that such failure shall have proximately 
and materially adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate 
counsel in any such Proceeding and to participate in the defense thereof, but 
the fees and expenses of such counsel shall be at the expense of such 
Indemnified Party or Parties unless:  (1) the Indemnifying Party has agreed 
in writing to pay such fees and expenses; or (2) the Indemnifying Party shall 
have failed promptly to assume the defense of such Proceeding and to employ 
counsel reasonably satisfactory to such Indemnified Party in any such 
Proceeding; or (3) the named parties to any such Proceeding (including any 
impleaded parties) include both such Indemnified Party and the Indemnifying 
Party, and such Indemnified Party shall have been advised by counsel that a 
conflict of interest is likely to exist if the same counsel were to represent 
such Indemnified Party and the Indemnifying Party (in which case, if such 
Indemnified Party notifies the Indemnifying Party in writing that it elects 
to employ separate counsel at the expense of the Indemnifying Party, the 
Indemnifying Party shall not have the right to assume the defense thereof and 
such counsel shall be at the expense of the Indemnifying Party).  The 
Indemnifying Party shall not be liable for any settlement of any such 
Proceeding effected without its written consent, which consent shall not be 
unreasonably withheld.  No Indemnifying Party shall, without the prior 
written consent of the Indemnified Party, effect any settlement of any 
pending Proceeding in respect of which any Indemnified Party is a party, 
unless such settlement includes an unconditional release of such Indemnified 
Party from all liability on claims that are the subject matter of such 
Proceeding.

          All fees and expenses of the Indemnified Party (including 
reasonable fees and expenses to the extent incurred in connection with 
investigating or preparing to defend such Proceeding in a manner not 
inconsistent with this Section) shall be paid to the Indemnified Party, as 
incurred, within 10 Business Days of written notice thereof to the 
Indemnifying Party (regardless of whether it is ultimately determined that an 
Indemnified Party is not entitled to indemnification hereunder; PROVIDED, 
that the Indemnifying Party may require such Indemnified Party to undertake 
to reimburse all such fees and expenses to the extent it is finally 
judicially determined that such Indemnified Party is not entitled to 
indemnification hereunder).

          (d)  CONTRIBUTION.  If a claim for indemnification under Section 
5(a) or 5(b) is unavailable to an Indemnified Party because of a failure or 
refusal of a governmental authority to enforce such indemnification in 
accordance with its terms (by reason of public policy or otherwise), then 
each Indemnifying Party, in lieu of indemnifying such Indemnified Party, 
shall contribute to the amount paid or payable by such Indemnified Party as a 
result of such Losses, in such proportion as is appropriate to reflect the 
relative fault of the Indemnifying Party and Indemnified Party in connection 
with the actions, statements or omissions that resulted in such Losses as 
well as any other relevant equitable considerations.  The relative fault of 
such Indemnifying Party and Indemnified Party shall be determined by 
reference to, among other things, whether any action in question, including 
any untrue or alleged untrue statement of a material fact or omission or 
alleged omission of a material fact, has been taken or 


                                      -13-



made by, or relates to information supplied by, such Indemnifying Party or 
Indemnified Party, and the parties' relative intent, knowledge, access to 
information and opportunity to correct or prevent such action, statement or 
omission.  The amount paid or payable by a party as a result of any Losses 
shall be deemed to include, subject to the limitations set forth in Section 
5(c), any reasonable attorneys' or other reasonable fees or expenses incurred 
by such party in connection with any Proceeding to the extent such party 
would have been indemnified for such fees or expenses if the indemnification 
provided for in this Section was available to such party in accordance with 
its terms; PROVIDED, HOWEVER, that no such limitation shall apply if such 
Losses result solely from the willful misconduct of such Holder.

          The parties hereto agree that it would not be just and equitable if 
contribution pursuant to this Section 5(d) were determined by PRO RATA 
allocation or by any other method of allocation that does not take into 
account the equitable considerations referred to in the immediately preceding 
paragraph. Notwithstanding the provisions of this Section 5(d), no Holder 
shall be required to contribute, in the aggregate, any amount in excess of 
the amount by which the proceeds actually received by such Holder from the 
sale of the Registrable Securities subject to the Proceeding exceeds the 
amount of any damages that such Holder has otherwise been required to pay by 
reason of such untrue or alleged untrue statement or omission or alleged 
omission.  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.

          The indemnity and contribution agreements contained in this Section 
are in addition to any liability that the Indemnifying Parties may have to 
the Indemnified Parties.

     6.   RULE 144

          As long as any Holder owns Shares, Warrants or Underlying Shares 
(as such term is defined in the Purchase Agreement), the Company covenants to 
timely file (or obtain extensions in respect thereof and file within the 
applicable grace period) all reports required to be filed by the Company 
after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange Act. 
As long as any Holder owns Shares, Warrants or Underlying Shares prior to 
the date on which all Holders may resell all of its Shares, Warrants or 
Underlying Shares without volume restrictions pursuant to Rule 144(k) 
promulgated under the Securities Act (as determined by counsel to the Company 
pursuant to a written opinion letter to such effect, addressed and acceptable 
to the Company's transfer agent for the benefit of and enforceable by any 
holder thereof), if the Company is not required to file reports pursuant to 
Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to 
the Holders and make publicly available in accordance with Rule 144(c) 
promulgated under the Securities Act annual and quarterly financial 
statements, together with a discussion and analysis of such financial 
statements in form and substance substantially similar to those that would 
otherwise be required to be included in reports required by Section 13(a) or 
15(d) of the Exchange Act, as well as any other information required thereby, 
in the time period that such filings would have been required to have been 
made under the Exchange Act.  The Company further covenants that it will take 
such further action as any Holder may reasonably request, all to the extent 
required from time to time to enable such Person to sell Underlying Shares 
without registration under the Securities Act within the limitation of the 
exemptions provided by Rule 144 promulgated under the Securities Act, 
including providing any legal opinions referred to in the Purchase 


                                      -14-



Agreement.  Upon the request of any Holder, the Company shall deliver to such 
Holder a written certification of a duly authorized officer as to whether it 
has complied with such requirements. 

     7.   MISCELLANEOUS

          (a)  REMEDIES.  In the event of a breach by the Company or by a 
Holder, of any of their obligations under this Agreement, each Holder or the 
Company, as the case may be, in addition to being entitled to exercise all 
rights granted by law and under this Agreement, including recovery of 
damages, will be entitled to specific performance of its rights under this 
Agreement. The Company and each Holder agree that monetary damages would not 
provide adequate compensation for any losses incurred by reason of a breach 
by it of any of the provisions of this Agreement and hereby further agrees 
that, in the event of any action for specific performance in respect of such 
breach, it shall waive the defense that a remedy at law would be adequate.

          (b)  NO INCONSISTENT AGREEMENTS.  Neither the Company nor any of 
its subsidiaries has, as of the date hereof, nor shall the Company or any of 
its subsidiaries, on or after the date of this Agreement, enter into any 
agreement with respect to its securities that is inconsistent with the rights 
granted to the Holders in this Agreement or otherwise conflicts with the 
provisions hereof. Except as disclosed in Schedule 2.1(u) of the Disclosure 
Letter, neither the Company nor any of its subsidiaries has previously 
entered into any agreement granting any registration rights with respect to 
any of its securities to any Person.  Without limiting the generality of the 
foregoing, without the written consent of the Holders of a majority of the 
then outstanding Registrable Securities, the Company shall not grant to any 
Person the right to request the Company to register any securities of the 
Company under the Securities Act unless the rights so granted are subject in 
all respects to the prior rights in full of the Holders set forth herein, and 
are not otherwise in conflict or inconsistent with the provisions of this 
Agreement.

          (c)  NO PIGGYBACK ON REGISTRATIONS.  Neither the Company nor any of 
its security holders (other than the Holders in such capacity pursuant hereto 
or as disclosed in Schedule 2.1(u) of the Disclosure Letter) may include 
securities of the Company in the Registration Statement other than the 
Registrable Securities or as disclosed in Schedule 2.1(u) of the Disclosure 
Letter, and the Company shall not after the date hereof enter into any 
agreement providing any such right to any of its security holders.

          (d)  PIGGY-BACK REGISTRATIONS.  If at any time when there is not an 
effective Registration Statement covering Underlying Shares, the Company 
shall determine to prepare and file with the Commission a registration 
statement relating to an offering for its own account or the account of 
others under the Securities Act of any of its equity securities, other than 
on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or 
their then equivalents relating to equity securities to be issued solely in 
connection with any acquisition of any entity or business or equity 
securities issuable in connection with stock option or other employee benefit 
plans, the Company shall send to each holder of Registrable Securities 
written notice of such determination and, if within twenty (20) days after 
receipt of such notice, any such holder shall so request in writing, the 
Company shall include in such registration statement all or any part of such 
Registrable Securities such holder requests to be registered; provided, 
however, that the Company shall not be required to register any Registrable 
Securities pursuant to this Section 7(d) that are eligible for sale pursuant 
to Rule 144(k) of the Commission.  In the case of an 


                                      -15-



underwritten public offering, if the managing underwriter(s) or 
underwriter(s) should reasonably object to the inclusion of the Registrable 
Securities in such registration statement, then if the Company after 
consultation with the Underwriter's Representative should reasonably 
determine that the inclusion of such Registrable Securities, would materially 
adversely affect the offering contemplated in such registration statement, 
and based on such determination recommends inclusion in such registration 
statement of fewer or none of the Registrable Securities of the Holders, then 
the Registrable Securities of CIBC shall first be excluded from such 
registration statement and if additional Registrable Securities must still be 
excluded from such registration statement then (x) the number of Registrable 
Securities of the Holders (excluding CIBC) included in such registration 
statement shall be reduced pro-rata among such Holders (based upon the number 
of Registrable Securities requested to be included in the registration), if 
the Company after consultation with the underwriter(s) recommends the 
inclusion of fewer Registrable Securities, or (y) none of the Registrable 
Securities of the Holders shall be included in such registration statement, 
if the Company after consultation with the underwriter(s) recommends the 
inclusion of none of such Registrable Securities; PROVIDED, HOWEVER, that if 
Securities are being offered for the account of other persons or entities as 
well as the Company, such reduction shall not represent a greater fraction of 
the number of Registrable Securities intended to be offered by the Holders 
than the fraction of similar reductions imposed on such other persons or 
entities (other than the Company).

          (e)  AMENDMENTS AND WAIVERS.  The provisions of this Agreement, 
including the provisions of this sentence, may not be amended, modified or 
supplemented, and waivers or consents to departures from the provisions 
hereof may not be given, unless the same shall be in writing and signed by 
the Company and the Holders of at least two-thirds of the then outstanding 
Registrable Securities; PROVIDED, HOWEVER, that, for the purposes of this 
sentence, Registrable Securities that are owned, directly or indirectly, by 
the Company, or an Affiliate of the Company are not deemed outstanding.  
Notwithstanding the foregoing, a waiver or consent to depart from the 
provisions hereof with respect to a matter that relates exclusively to the 
rights of Holders and that does not directly or indirectly affect the rights 
of other Holders may be given by Holders of at least a majority of the 
Registrable Securities to which such waiver or consent relates; PROVIDED, 
HOWEVER, that the provisions of this sentence may not be amended, modified, 
or supplemented except in accordance with the provisions of the immediately 
preceding sentence.

          (f)  NOTICES.  Any and all notices or other communications or 
deliveries required or permitted to be provided hereunder shall be in writing 
and shall be deemed given and effective on the earliest of (i) the date of 
transmission, if such notice or communication is delivered via facsimile at 
the facsimile telephone number specified in this Section prior to 8:00 p.m. 
(Eastern Standard Time) on a Business Day, (ii) the Business Day after the 
date of transmission, if such notice or communication is delivered via

Agreement later than 8:00 p.m. (Eastern Standard Time) on any date and 
earlier than 11:59 p.m. (Eastern Standard Time) on such date, (iii) the 
Business Day following the date of mailing, if sent by nationally recognized 
overnight courier service, or (iv) upon actual receipt by the party to whom 
such notice is required to be given to each Holder at its address set forth 
under its name on SCHEDULE 1 attached hereto or such other address as may be 
designated in writing hereafter, in the same manner, by such Person.  Copies 
of notices to any 


                                      -16-

sent to Wilson Sonsini Goodrich & Rosati, a professional corporation, Attn: 
Andrew J. Hirsch, Esq., fax: (650) 354-4210.

          (g)  SUCCESSORS AND ASSIGNS.  This Agreement shall inure to the 
benefit of and be binding upon the successors and permitted assigns of each 
of the parties and shall inure to the benefit of each Holder.  The Company 
may not assign its rights or obligations hereunder without the prior written 
consent of each Holder.  Each Purchaser may assign its rights hereunder in 
the manner and to the Persons as permitted under the Purchase Agreement.

          (h)  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights of each Holder 
hereunder, including the right to have the Company register for resale 
Registrable Securities in accordance with the terms of this Agreement, shall 
be automatically assignable by each Holder to any Affiliate of such Holder, 
any other Holder or Affiliate of any other Holder and up to four other 
assignees of all or a portion of the shares of Preferred Stock, the Warrants 
or the Registrable Securities if: (i) the Holder agrees in writing with the 
transferee or assignee to assign such rights, and a copy of such agreement is 
furnished to the Company within a reasonable time after such assignment, (ii) 
the Company is, within a reasonable time after such transfer or assignment, 
furnished with written notice of (a) the name and address of such transferee 
or assignee, and (b) the securities with respect to which such registration 
rights are being transferred or assigned, (iii) following such transfer or 
assignment the further disposition of such securities by the transferee or 
assignees is restricted under the Securities Act and applicable state 
securities laws, (iv) at or before the time the Company receives the written 
notice contemplated by clause (ii) of this Section, the transferee or 
assignee agrees in writing with the Company to be bound by all of the 
provisions of this Agreement, and (v) such transfer shall have been made in 
accordance with the applicable requirements of the Purchase Agreement.  The 
rights to assignment shall apply to the Holders (and to subsequent) 
successors and assigns.

          (i)  COUNTERPARTS.  This Agreement may be executed in any number of 
counterparts, each of which when so executed shall be deemed to be an 
original and, all of which taken together shall constitute one and the same 
Agreement. In the event that any signature is delivered by facsimile 
transmission, such signature shall create a valid binding obligation of the 
party executing (or on whose behalf such signature is executed) the same with 
the same force and effect as if such facsimile signature were the original 
thereof.

          (j)  GOVERNING LAW.  This Agreement shall be governed by and 
construed in accordance with the laws of the State of New York, without 
regard to principles of conflicts of law. 

          (k)  CUMULATIVE REMEDIES.  The remedies provided herein are 
cumulative and not exclusive of any remedies provided by law. 

          (l)  SEVERABILITY. If any term, provision, covenant or restriction 
of this Agreement is held by a court of competent jurisdiction to be invalid, 
illegal, void or unenforceable, the remainder of the terms, provisions, 
covenants and restrictions set forth herein shall remain in full force and 
effect and 


                                      -17-



shall in no way be affected, impaired or invalidated, and the parties hereto 
shall use their reasonable efforts to find and employ an alternative means to 
achieve the same or substantially the same result as that contemplated by 
such term, provision, covenant or restriction.  It is hereby stipulated and 
declared to be the intention of the parties that they would have executed the 
remaining terms, provisions, covenants and restrictions without including any 
of such that may be hereafter declared invalid, illegal, void or 
unenforceable.

          (m)  HEADINGS.  The headings in this Agreement are for convenience 
of reference only and shall not limit or otherwise affect the meaning hereof.

          (n)  SHARES HELD BY THE COMPANY AND ITS AFFILIATES.  Whenever the 
consent or approval of Holders of a specified percentage of Registrable 
Securities is required hereunder, Registrable Securities held by the Company 
or its Affiliates (other than any Holder or transferees or successors or 
assigns thereof if such Holder is deemed to be an Affiliate solely by reason 
of its holdings of such Registrable Securities) shall not be counted in 
determining whether such consent or approval was given by the Holders of such
