               Item 3.   Source and Amount of Funds or Other Consideration.

               The general and limited partners of the Sprout Funds
contributed $17,553,900 for 2,771,588 Shares.  Such price was funded through
internally generated funds.

               Item 4. Purpose of Transaction.

               The Sprout Funds have acquired the 7.0% Convertible
Subordinated Notes (the "Notes"), of the Company and the shares of Series D
Preferred Stock no par value (the "Series D Preferred Stock"), of the Company
(together, the "Securities") for general investment purposes.  The Sprout
Funds reserve the right to change their business intent.  Subject to the
agreements discussed herein or attached hereto, and to market conditions and
other factors, the Sprout Funds or other affiliates of DLJ may acquire or
dispose of Securities from time to time in the future.  The Sprout Funds may
enter into agreements with third parties relating to acquisitions of
securities, or open market, privately negotiated or other transactions. The
Sprout Funds may enter into agreements with management of the Company relating
to acquisitions of shares by members of management, issuances of options to
management or may affect other similar agreements or transactions.  Except as
set forth herein, the Sprout Funds have no plan or proposals which relate to or
would result in any of the transactions described in subparagraphs (a) through
(j) of Item 4 of Schedule 13D.

               Pursuant to the Securities Purchase Agreement (the "Purchase
Agreement"), dated May 12, 1998, by and among the Company, Chase Venture
Capital Associates, L.P. ("CVCA") and Sprout Capital VII, L.P. and Sprout
Growth II, L.P. and certain of their affiliated entities (collectively with
CVCA, the "Investors") the Sprout Funds acquired from the Company $9,181,321
in aggregate principal amount of 7.0% Convertible Subordinated Notes and
332,305 shares of Series D Preferred Stock.  The Purchase Agreement is
attached hereto as Exhibit D and is incorporated by reference herein.

               In order to create the Series A Preferred Stock, no par value
(the "Series A Preferred Stock") of the Company, the Series B Preferred Stock,
no par value (the "Series B Preferred Stock"), of the Company, the Series C
Preferred Stock, no par value (the "Series C Preferred Stock") of the Company
and the Series D Preferred Stock, the Company filed the Amendment to Restated
Articles of Incorporation (the "Amendment") on May 14, 1998, attached hereto
and incorporated herein by reference as Exhibit E.

               Pursuant to the Purchase Agreement, the Notes are initially
convertible into 996,886 shares of Common Stock and, as described in the
Amendment, the Series D Preferred Stock is initially convertible into 332,305
shares of Common Stock. The number of shares of Common Stock issuable upon
conversion of such securities increases by one share for every $9.21 of
accrued interest or dividends which the Company elects not to pay in cash.
Also, pursuant to customary anti-dilution provisions contained in the Notes
and the Series D Preferred Stock, the number of shares of the Common Stock
issuable upon conversion of such securities shall be adjusted with respect to
stock splits and combinations, stock dividends, below market sales,
distributions, mergers, consolidations, reorganizations or preferred or
convertible security sales.  Upon the satisfaction of certain conditions
precedent set forth in the Purchase Agreement, the Notes shall automatically
be deemed to convert into shares of the Series B Preferred Stock or exchanged
for new notes of a new holding company that owns all of the outstanding
capital stock of the Company.  The terms of such Series B Preferred Stock and
new notes shall be substantially similar to that of the Notes.

               The Purchase Agreement contains covenants regarding the
transfer of Securities.  Investors must provide written notice, and in some
cases opinions of counsel, to the Company prior to transferring any of the
Securities.  No Investor shall transfer its Securities, without the prior
written consent of the Company, to any competitor of the Company.

               The Purchase Agreement provides that the Investors shall have
access to the records of the Company and that the Company shall furnish its
financial reports to each of the Investors.  The Company covenants that it
shall, among other things, pay its taxes, preserve its corporate existence,
maintain and preserve its properties and use its best efforts to upgrade the
listing of the Common Stock from the NASDAQ SmallCap Market System to the
NASDAQ National Market System within 90 days of the First Closing.  The
Company covenants that it shall not, among other things, change the nature of
its business, permit the Board (other than members appointed by the Investors)
to exceed 15 members or make fundamental changes in the structure of the
Company.

               Item 5.  Interest in Securities of the Issuer.

               (a) and (b) In a series of transactions in 1996 and 1997, the
Sprout Funds acquired and for the purpose of Rule 13d-3 promulgated under the
Exchange Act, are deemed to beneficially own 1,442,397 Shares.  The Sprout
Funds, through their ownership of 332,305 shares of Series D Preferred Stock
and $9,181,321 aggregate principal amount of Notes, have acquired and, for the
purpose of Rule 13d-3 promulgated under the Exchange Act, beneficially own an
additional  1,329,191 Shares, representing approximately 12.6% of the
outstanding Shares of the Issuer.  In total, the Sprout Funds, for the purpose
of rule 13d-3 promulgated under the Exchange Act, own 2,771,588 Shares,

Requirements), applicable to it and its business and (ii) has all federal,
state, local and foreign governmental licenses and permits (collectively,
"Permits") used or necessary in the conduct of its business, except where such
failure to obtain any Permit, individually or in the aggregate, has not had
nor could it reasonably be expected to have a Material Adverse Effect on the
Company and each of its Subsidiaries taken together as a whole. Such Permits
are in full force and effect, no violations with respect to any thereof have
occurred or are or have been recorded, no Proceeding is pending or, to the
Best Knowledge of the Company, threatened to revoke or limit any thereof.
Schedule 3.12 contains a true, correct and complete list of (A) all such
material Permits and (B) all Orders under which the Company and the
Subsidiaries is operating or bound. To the Best Knowledge of the Company,
there is no proposed change in any applicable Legal Requirement which would
require the Company or any of the Subsidiaries to obtain any material Permits
not set forth on Schedule 3.12 in order to conduct the business of the Company
and the Subsidiaries as each is presently conducted and as presently proposed
to be conducted. None of such Permits or Orders shall be adversely affected as
a result of the Company's execution and delivery of, or the performance of its
obligations under, any Document to which it is a party, or the consummation of
the transactions contemplated thereby. Neither the Company nor any of the
Subsidiaries has received any opinion or memorandum or legal advice from legal
counsel to the effect that it is exposed, from a legal standpoint, to any
Liability or disadvantage which may be material to its business, financial
condition, operations, property or affairs. Except as set forth on Schedule
3.12, the Company, after due inquiry, is not aware of any proposed Legal
Requirement which would prohibit or restrict the Company or any of the
Subsidiaries from, or otherwise materially adversely affect the Company or any
of the Subsidiaries in, conducting each of their businesses in any jurisdiction
in which each is now conducting business or which it proposes to conduct
business. To the Best Knowledge of the Company, there are no facts or
circumstances that could reasonably indicate that the Company's proposed
acquisition of Dedicated Dental will not be approved by the Department of
Corporations of the State of California.

3.13.         Taxes.

              Except as disclosed on Schedule 3.13, (a) the Company and each
other Person included in any consolidated or combined Tax Return and part of an
affiliated group, within the meaning of Section 1504 of the Code, of which the
Company and each Subsidiary is or has been a member has filed all returns,
declarations of estimated tax, tax reports, information returns and statements
(collectively, the "Returns") required to be filed by it (other than those for
which extensions have been granted and have not expired) relating to any Taxes
(as defined below); (b) as of the time of filing, the Returns were complete and
correct in all material respects and all Taxes shown on the Returns have been
paid; (c) the Company and each Subsidiary has paid or made provisions for all
Taxes payable for any period that ended on or before the date hereof and for
any period that began on or before the date hereof and ends after the date
hereof, to the extent such Taxes are attributable to the portion of any such
period ending on the date hereof; (d) the Company and each Subsidiary is not
delinquent in the payment of any Taxes nor has it requested any extension of
time within which to file any Return, which Return has not since been filed;
(e) there are no pending tax audits of any Returns of the Company or any
Subsidiary, and neither the Company nor any Subsidiary has received notice of
any pending tax audits of any Returns of the Company or any Subsidiary; (f) no
tax liens have been filed and no deficiency or addition to Taxes, interest or
penalties for any Taxes have been proposed, asserted or assessed in writing
against the Company or any Subsidiary; (g) neither the Company nor any
Subsidiary has granted any extension of the statute or any Subsidiary of
limitations applicable to any Return or other Tax claim with respect to any of
its respective income, properties or operations or any Subsidiary; (h) the
Company and the Subsidiaries have complied in all material respects with all
applicable Legal Requirements relating to the payment and withholding of Taxes
(including sales and use Taxes, and amounts required by law to be withheld and
paid from the wages or salaries of employees), and neither the Company nor any
Subsidiary is liable for any Taxes for failure to comply with any such Legal
Requirement, except where such failure to make payment or withhold Taxes has
not had nor could it reasonably be expected to have a Material Adverse Effect
on the Company and each of its Subsidiaries taken together as a whole; and (i)
neither the Company nor any Subsidiary has agreed to, is not required to, and
will not be obligated to, make any adjustments either on, before or after the
date hereof, to its existing tax accounting method by reason of Section 481 of
the Code, or due to a determination by the Board of Directors of the Company
(acting on the advice of the Company's accountant, as the case may be) that any
existing method of accounting is not permissible or appropriate, and the
Internal Revenue Service has not proposed any such adjustments or changes in
the Company's accounting method.

3.14.         Labor Relations.

              Schedule 3.14 sets forth a list of all directors, officers and
key employees of the Company and the Subsidiaries as of the date hereof,
together with their respective titles (if any), their current compensation
(including salary, wages, bonuses and commissions) and the respective dates on
which they commenced employment, the number of Common Stock Equivalents held
by such person (including in the case of options or warrants, the exercise
price related thereto) and if applicable, the expiration date of such
officer's or key employee's employment agreement. To the Best Knowledge of the
Company, none of the employees listed on Schedule 3.14 has any plans or
intends to terminate his or their employment or engagement with the Company or
the Subsidiaries.

3.15.         ERISA Plans and Contracts.

              Schedule 3.15 hereto contains a true and complete list of all
Employee Plans. Neither the Company nor any of its ERISA Affiliates is or has
ever maintained or been obligated to contribute a "multiple employer plan" (as
defined in Section 413 of the Code), a "multiemployer plan" (as defined in
Section 3 (37) of ERISA) or a "defined benefit pension plan" (as defined in
Section 3(35) of ERISA). Neither the Company nor any of its ERISA Affiliates
maintains or has maintained any Employee Plan providing or agreeing to provide
any post-retirement health or welfare benefits to employees, former employees
or retired employees of the Company or its ERISA Affiliates or beneficiaries
of such employees.

3.16.         Related Party Transactions.

              Except as set forth on Schedule 3.16, and, except for reasonable
compensation to regular employees of the Company and any Affiliate for
services rendered in the ordinary course of business, no current or former
Affiliate of the Company or any "Associate" (as defined in the rules and
regulations promulgated under the Exchange Act) thereof, is presently, or
during the last three fiscal years (or since inception, if shorter) has been,
(i) a party to any agreement or transaction with the Company or any of its
Subsidiaries (including, but not limited to, any contract, agreement or other
arrangement providing for the furnishing of services by, or rental of real or
personal property from, or otherwise requiring payments to, any such Affiliate
or Associate) or (ii) the direct or indirect owner of an interest in any Person
which is a present or potential competitor, supplier or customer of the Company
or any its Subsidiaries (other than non-affiliated holdings in publicly held
companies), nor does any such Person receive income from any source other than
the Company which relates to the business of, or should properly accrue to, the
Company. Except as set forth on Schedule 3.16, the Company and each of its
Subsidiaries is not a guarantor or otherwise liable for any actual or potential
Liability or obligation, whether direct or indirect, of any of its Affiliates.

3.17.         Private Sale.

              Assuming the accuracy of the representations of the Purchasers
in Section 4.2, the offering, sale, and issuance of the Purchased Notes, the
Preferred Shares and the Reserved Common Shares, as the case may be, will be,
exempt from registration under the Securities Act and applicable state
securities laws and the rules and regulations promulgated thereunder. Neither
the Company nor any Person authorized or employed by the Company as agent,
broker, dealer or otherwise in connection with the offering, sale or issuance
of the Purchased Notes or the Preferred Shares has offered the same for sale
to, or solicited any offers to buy the same from, or otherwise approached or
negotiated with respect thereto, any Person or Persons other than the
Purchasers.

3.18.         Brokers.

              Except for the Company's engagement of Bear Stearns & Co. Inc.,
in connection with this transaction, and the closing fee payable to the
Purchasers in an amount equal to 1% of aggregate principal amount of the
Purchased Notes, neither the Company nor any of its officers, directors,
stockholders or employees (or any Affiliate of the foregoing) has employed any
broker or finder or incurred any actual or potential Liability or obligation,
whether direct or indirect, for any brokerage fees, commissions or finders'
fees in connection with the transactions contemplated by this Agreement.

3.19.         Insurance.

              Schedule 3.19 hereto lists and briefly describes each insurance
policy maintained by the Company and the Subsidiaries with respect to the
properties, assets and business of the Company and the Subsidiaries (the
"Insurance Policies"). All of such Insurance Policies are in full force and
effect, and neither the Company nor any of the Subsidiaries is in default in
any material respect with respect to its obligations under any of such
insurance policies and has not received any notification of cancellation of any
of such Insurance Policies and has no claim outstanding which could be expected
to cause a material increase in the insurance rates. To the Best Knowledge of
the Company, no facts or circumstances exist that would relieve any insurer
under any such policies of their obligations to satisfy in full any claim of
the Company thereunder. The Company has not received any notice that (i) any of
such policies has been or will be canceled or terminated or will not be renewed
on substantially the same terms as are now in effect or (ii) the premium on any
of such policies will be materially increased on the renewal thereof. The
Company maintains insurance for its benefit in amounts and against all risks
that are normal and customary for Persons operating similar properties and
businesses under policies in effect and issued by insurers of
recognized responsibility.

3.20.         Disclosure.

              Neither this Agreement nor any of the Schedules or Exhibits,
including the financial projections delivered to the Purchasers in connection
with the execution and delivery of this Agreement, when taken together,
contains any untrue statement of a material fact or omits a material fact
necessary to make the statements contained herein and therein, in light of the
circumstances in which they were made, not misleading. To the Best Knowledge
of the Company, there is no fact, circumstance or condition which has had or
could reasonably be expected to have a Material Adverse Effect on the Company
and the Subsidiaries, taken as a whole which has not been set forth in this
Agreement or in the Schedules or the Exhibits. Except for the provisions of
the Documents, neither the Company nor any of the Subsidiaries is obligated
under any contract or agreement or subject to any restriction set forth in its
Fundamental Documents or subject to any other restriction which has or could
reasonably be expected to have a Material Adverse Effect on the Company and
the Subsidiaries, taken as a whole.

3.21.         Accounts and Notes Receivable.

              Except as set forth on Schedule 3.21, all of the accounts
receivable and notes receivable owing to the Company as of the date hereof
constitute, and as of the date hereof will constitute, valid and enforceable
claims arising from bona fide transactions in the ordinary course of business,
and there are no known or asserted claims, refusals to pay or other rights of
set-off against any thereof. Except to the extent of reserves established by
the Company specifically for doubtful accounts and notes receivable (which
reserves are set forth in the Financial Statements, are reasonable under the
circumstances and are consistent with past practice), to the Best Knowledge of
the Company, each account receivable of the Company existing as of the date
hereof shall be paid in full not later than the 90th day after the date such
account receivable was created and all of the notes receivable shall be paid in
accordance with the terms thereof. Except as set forth on Schedule 3.21, as of
the date hereof, there is (i) no account debtor or note debtor delinquent in
its payment by more than 90 days, (ii) no account debtor or note debtor that
has refused or threatened to refuse to pay its obligations for any reason,

that is insolvent or bankrupt and (iv) no account receivable or note receivable
pledged to any third party by the Company.

3.22.         Registration Rights.

              Except as contemplated by the Registration Rights Agreement and
as set forth on Schedule 3.22, no Person has any right to cause the Company to
effect the registration under the Securities Act of any shares of Common Stock
or any other Securities of the Company.

3.23.         Year 2000.

              To the Best Knowledge of the Company, all billing and other data
processing programs used by the Company are designed to be used prior to,
during and after the calendar year 2000 A.D., and such programs will operate
during each such time period without error relating to date data and
date-dependent data, specifically including any error relating to, or the
program of, date data which represents or references different centuries or
more than one century other than such errors which have not had nor could
reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect on the Company and its Subsidiaries taken together as a whole.
Other than any of the following which has not had nor could reasonably be
expected to have a Material Adverse Effect, individually or in the aggregate,
on the Company and its Subsidiaries taken together as a whole to the Best
Knowledge of the Company without limiting the generality of the foregoing:

              (a) each such program will not abnormally end or provide invalid
or incorrect results as a result of date data, specifically including date data
which represents or references different centuries or more than one century;

              (b) each such program has been designed to ensure Year 2000
compatibility, including, but not limited to, date data century recognition,
calculations which accommodate same century and multi-century formulas and
date values and date data interface values that reflect the century; and

              (c) each such program includes "Year 2000 Capabilities." For the
purposes hereof, "Year 2000 Capabilities" means each such program:

                  (i) manages and manipulates data involving date, including
         single century formulas and multi-century formulas, and will not
         cause an abnormally ending scenario within the application or
         generate incorrect values or invalid results involving such dates;

                  (ii) provides that all date-related interface
         functionalities and data fields include the indication of century;
         and

                  (iii) provides that all date-related data interface
         functionalities include the indication of century.

                                  ARTICLE IV

               REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

              Each Purchaser represents and warrants to the Company as to
itself severally, and not jointly as to any other Purchaser, as of the date
hereof, as follows:

4.1.          Authorization of the Documents.

              Such Purchaser has all requisite power and authority to execute,
deliver and perform the Documents to which it is a party and the transactions
contemplated thereby, and the execution, delivery and performance by such
Purchaser of the Documents to which it is a party have been duly authorized by
all requisite action by such Purchaser and each such Document constitutes a
valid and binding obligation of such Purchaser enforceable against such
Purchaser in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization, fraudulent conveyance, moratorium or other similar
laws and subject to general principles of equity.

4.2.          Investment Representations.

              Solely for establishing that the sale or issuance of the
Purchased Notes, Preferred Shares and Reserved Common Shares (if any), to such
Purchaser is exempt from the registration requirements of Section 5 of the
Securities Act and comparable provisions of state blue-sky laws and not in any
way to mitigate the responsibility or liability of the Company for any breach
of the representations and warranties made by it in this Agreement, on which
such Purchaser is relying in full in connection with its decision to invest in
the Company:

              (a) Such Purchaser is acquiring the Purchased Notes and
Preferred Shares to be purchased hereunder and, in the event that such
Purchaser should acquire any Reserved Common Shares, will be acquiring such
Reserved Common Shares, for its own account, for investment and not with a
view to the distribution thereof in violation of the Securities Act or
applicable state securities laws.

              (b) Such Purchaser understands that (i) the Purchased Notes and
Preferred Shares have not been, and the Reserved Common Shares will not be,
registered under the Securities Act or applicable state securities laws by
reason of their issuance by the Company in a transaction exempt from the
registration requirements of the Securities Act and applicable state
securities laws and (ii) the Purchased Notes and Preferred Shares, and if
acquired, the Reserved Common Shares must be held by such Purchaser
indefinitely unless a subsequent disposition thereof is registered under the
Securities Act and applicable state securities laws or is exempt from such
registration.

              (c) Each Purchaser further understands that the exemption from
registration afforded by Rule 144 (the provisions of which are known to such
Purchaser) promulgated under the Securities Act depends on the satisfaction of
various conditions, and that, if applicable, Rule 144 may only afford the
basis for sales of Securities acquired hereunder only in limited amounts.

              (d) Such Purchaser has not employed any broker or finder in
connection with the transactions contemplated by this Agreement.

              (e) Such Purchaser is an "accredited investor" (as defined in
Rule 501(a) of Regulation D promulgated under the Securities Act). The Company
has made available to such Purchaser or its representatives all agreements,
documents, records and books that such Purchaser has requested relating to an
investment in the Securities which may be acquired by the Purchaser hereunder.
Such Purchaser has had an opportunity to ask questions of, and receive answers
from, a person or persons acting on behalf of the Company, concerning the
terms and conditions of this investment, and answers have been provided to all
of such questions to the full satisfaction of such Purchaser. Such Purchaser
has such knowledge and experience in financial and business matters that it is
capable of evaluating the risks and merits of this investment. Such
Purchaser's representations in this subsection shall in no way limit the
enforceability of any representations made by the Company in any of the
Documents to which it is a party.

              (f) The state in which any offer to purchase Purchased Notes or
Preferred Shares hereunder was made to or accepted by such Purchaser is the
state shown as the Purchaser's address on Schedule I hereto.

              (g) Such Purchaser was not formed for the purpose of investing
solely in the Securities which may be acquired hereunder.

                                  ARTICLE VI

                                INDEMNIFICATION

6.1.          Survival of Representations, Warranties, Agreements and
Covenants, Etc.

              All statements contained in any other Document or any closing
certificate delivered by the Company or the Purchasers, pursuant to this
Agreement or in connection with the transactions contemplated by this
Agreement (each, a "Closing Certificate"), shall constitute representations
and warranties by the Company, or the Purchasers, as applicable, under this
Agreement. Notwithstanding any investigation made at any time by or on behalf
of any party hereto, all representations and warranties contained in this
Agreement or made in writing by or on behalf of the Company, or an Purchaser,
in connection with the transactions contemplated by this Agreement shall
survive the Closing until the third anniversary of the First Closing Date,
provided however, that the representations and warranties contained in
Sections 3.1, 3.2, 3.3, 3.4, 3.5, 3.12, 3.17 and 3.18 and 3.23 shall survive
the Closings indefinitely and the representation and warranties contained in
3.13 shall survive the Closings and continue in full force and effect for the
period of the statute of limitations applicable to the matters covered
thereby.

6.2.          Indemnification.

              (a) In addition to all other rights and remedies available to the
Purchasers, the Company shall indemnify, defend and hold harmless each
Purchaser and its Affiliates and their respective partners, officers,
directors, employees, agents and representatives (collectively, the "Purchaser
Representatives"; and together with such Purchaser, the "Purchaser Indemnified
Persons") against all Losses, and none of the Purchaser Indemnified Persons
shall be liable to the Company or any other stockholder of the Company for or
with respect to any and all Losses, together with all costs and expenses
(including legal and accounting fees and expenses) related thereto or incurred
in enforcing this Article VI, (i) arising from the untruth, inaccuracy or
breach of any of the representations or warranties of the Company contained in
any Document or Closing Certificate or any facts or circumstances constituting
any such untruth, inaccuracy or breach, (ii) arising from the breach of any
covenant or agreement of the Company contained in any Document or Closing
Certificate or any facts or circumstances constituting such breach, or (iii)
arising from any Claim, except for any Claim made by the Company against such
Purchaser pursuant to Section 6.2(b) (whenever made), resulting from or caused
by any transaction, status, event, condition, occurrence or situation relating
to, arising out of or in connection with (A) the status of, or conduct of the
business and affairs of, the Company or (B) the execution, delivery and
performance of this Agreement and the other Documents and the related documents
and agreements contemplated hereby and thereby. Notwithstanding the foregoing,
and subject to the following part of this sentence, upon judicial
determination, which is final and no longer appealable, that the act or
omission giving rise to the indemnification pursuant to clause (iii) of Section
6.2(a) resulted primarily out of or was based primarily upon the indemnified
party's gross negligence, fraud or willful misconduct, (unless such action was
based upon the indemnified party's reliance in good faith upon any of the
representations, warranties, covenants or promises made by the Company herein,
or in the Documents), the Company shall not be responsible for any Losses
sought to be indemnified in connection therewith, and the Company shall be
entitled to recover from the indemnified party all amounts previously paid in
full or partial satisfaction of such indemnity, together with all costs and
expenses of the Company reasonably incurred in effecting such recovery, if any.

              (b) In addition all other rights and remedies available to the
Company, each Purchaser severally as to itself only and not as to any other
Purchaser, shall indemnify, defend and hold harmless the Company and its
officers, directors, employees, agents and representatives (collectively, the
"Company Indemnified Persons,") against all Losses, together with all
reasonable out-of-pocket costs and expenses (including legal and accounting
fees and expenses) related thereto or incurred in enforcing this Article VI,
(i)arising from the untruth, inaccuracy or breach of any of the
representations or warranties of such Purchaser contained in any Document or
Closing Certificate or any facts or circumstances constituting such untruth,
inaccuracy or breach or (ii) arising from the breach of any covenant or
agreement of such Purchaser contained in any Document or Closing Certificate
or any facts or circumstances constituting such breach.

              (c) If for any reason the indemnity provided for in this Section
is unavailable to any Indemnified Person or is insufficient to hold each such
Indemnified Person harmless from all such Losses arising with respect to the
transactions contemplated by this Agreement, then the Indemnifying Persons
shall contribute to the amount paid or payable for such Losses in such
proportion as is appropriate to reflect not only the relative benefits received
by the Indemnifying Persons on the one hand and such Indemnified Person on the
other but also the relative fault of the Indemnifying Persons and the
Indemnified Person as well as any relevant equitable considerations. In
addition, the Indemnifying Persons shall reimburse any Indemnified Person upon
demand for all reasonable expenses (including reasonable fees of legal counsel)
incurred by such Indemnified Person in connection with investigating, preparing
for or defending any such action or claim. The indemnity, contribution and
expenses reimbursement obligations that the Indemnifying Persons have under
this Article VI shall be in addition to any Liability that the Indemnifying
Persons may otherwise have. The Indemnifying Persons further agree that the
indemnification and reimbursement commitments set forth in this Agreement shall
apply whether or not the Indemnified Person is a formal party to any such
Claim.

              (d) Any indemnification of an Indemnified Person by Indemnifying
Persons pursuant to this Section shall be effected by wire transfer of
immediately available funds from the Indemnifying Persons to an account
designated by the Indemnified Person within 15 days after the determination
thereof.

              (e) All indemnification rights hereunder shall survive the
execution and delivery of the Documents and the consummation of the
transactions contemplated herein and therein indefinitely, regardless of any
investigation, inquiry or examination made for or on behalf of, or any
knowledge of the Purchaser and/or any of the other Indemnified Parties or the
acceptance by the Purchaser of any certificate or opinion.

              (f) By executing this Agreement, the Company (i) agrees no
Purchaser Indemnified Person shall have any liability to the Company or its
Subsidiaries pursuant to this Agreement, the other Documents or the
transactions contemplated hereby or thereby (the "Covered Conduct") except (A)
as provided in Section 6.2(b), and (B) to the extent that a court of competent
jurisdiction shall have determined by final judgment, no longer subject to
appeal, that the losses resulting from such Covered Conduct primarily resulted
from or was based primarily upon such Purchaser Indemnified Person's willful
misconduct or gross negligence, (ii) agrees that it will not make under any
circumstances, and it will cause its Subsidiaries not to make under any
circumstances, any claim against any Purchaser Indemnified Person, with respect
to a claim or loss with respect to which such Person is entitled to
indemnification hereunder, for any special, indirect or consequential damages
in respect of any breach or wrongful conduct (whether the claim therefore is
based on contract, tort or duty imposed by law) in connection with, arising out
of or in any way related to, the transactions contemplated by and the
relationship established by this Agreement, the other Documents or the
transactions contemplated hereby or thereby, or any act, omission or event
occurring in connection therewith, and (iii) waive, release and agree not to
sue upon, and it agrees to cause its Subsidiaries not to sue upon, and it
agrees to cause its Subsidiary not to sue upon any such claim for any such
damages, whether or not accrued and whether or not known or suspected to exist
in any such party's favor.

                            TRANSFER OF SECURITIES

7.1.          Restriction on Transfer.

              The Restricted Securities shall not be transferable except upon
the conditions specified in this Article VII, which conditions are intended to
insure compliance with the provisions of the Securities Act in respect of the
transfer thereof.

7.2.          Restrictive Legends.

              Each certificate evidencing the Restricted Securities and each
certificate for any such securities issued to subsequent transferees of any
such certificate shall (unless otherwise permitted by the provisions of
Section 7.3 hereof) be stamped or otherwise imprinted with a legend in
substantially the following form:

              "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
              ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
              SECURITIES ACT OF 1933. THESE SECURITIES MAY NOT BE SOLD OR
              TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION
              THEREFROM UNDER SAID ACT OR APPLICABLE STATE BLUE SKY LAWS.
              ADDITIONALLY, THE TRANSFER OF THESE SECURITIES IS SUBJECT TO THE
              CONDITIONS SPECIFIED IN THE SECURITIES PURCHASE AGREEMENT DATED
              AS OF MAY 12, 1998, AMONG THE ISSUER HEREOF AND CERTAIN OTHER
              SIGNATORIES THERETO, AND NO TRANSFER OF THESE SECURITIES SHALL BE
              VALID OR EFFECTIVE UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED.
              COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN
              REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
              SECRETARY OF THE ISSUER HEREOF."

7.3.          Notice of Transfer.

              (a)   The holder of any Restricted Securities, by acceptance
thereof agrees, prior to any Transfer of any Restricted Securities, to give
written notice to the Company of such holder's intention to effect such
transfer and to comply in all other respects with the provisions of this
Section 7.3. Each such notice shall describe the manner and circumstances of
the proposed transfer and shall be accompanied by (i)the written opinion,
addressed to the Company, of counsel for the holder of Restricted Securities,
as to whether in the opinion of such counsel (which opinion and counsel shall
be reasonably satisfactory to the Company) such proposed transfer involves a
transaction requiring registration of such Restricted Securities under the
Securities Act, and (ii)in the case of Restricted Shares, if in the opinion of
such counsel such registration is required, a written request addressed to the
Company by the holder of Restricted Shares, describing in detail the proposed
method of disposition and requesting the Company to effect the registration of
such Restricted Shares pursuant to the terms and provisions of the Registration
Rights Agreement; provided, however, that (A)in the case of a holder of
Restricted Securities which is a partnership, no such opinion of counsel shall
be necessary for a Transfer by such holder of Restricted Securities to a
partner of such holder of Restricted Securities, or a retired partner of such
holder who retires after the date hereof, or the estate of any such partner or
retired partner, if in each case the transferee agrees in writing to be subject
to the terms of this Article VII to the same extent as if such transferee were
originally a signatory to this Agreement, and (B) no such opinion shall be
required in connection with a Transfer pursuant to Rule 144 (as amended from
time to time) promulgated under the Securities Act (or successor rule thereto),
provided, that the Company, shall be provided with customary written
representations relating to such transaction.

               (b)   If in the opinion of such counsel (if such opinion is
required hereunder) the proposed Transfer of Restricted Securities may be
effected without registration under the Securities Act, the holder of
Restricted Securities shall thereupon be entitled to Transfer Restricted
Securities in accordance with the terms of the notice delivered by it to the
Company.

               (c)   Each certificate or other instrument evidencing the
securities issued upon the transfer of any Restricted Securities (and each
certificate or other instrument evidencing any untransferred balance of such
securities) shall bear the legend set forth in Section 7.2 hereof unless (i)
in the opinion of such counsel registration of future Transfer is not required
by the applicable provisions of the Securities Act or (ii) the Company shall
have waived the requirement of such legends; provided, however, that such
legend shall not be required on any certificate or other instrument evidencing
the securities issued upon such Transfer in the event such Transfer shall be
made in compliance with the requirements of Rule144 (as amended from time to
time) promulgated under the Securities Act (or successor rule thereto).

7.4.          Transfer Pursuant to Rule 144.

              The Company agrees to provide to the holders of the Restricted
Securities and upon a holder's request to any prospective purchasers
designated by a holder the financial and other information specified in Rule
144 under the Securities Act and to take any other action or to execute any
certificates necessary to permit a transfer by any holder of Restricted
Securities to qualify for the exemption set forth in Rule 144.

7.5.          Transfers to Competitors.

              No Purchaser shall, without the prior written consent of the
Company, Transfer in a private transaction, any Purchased Notes or Additional
Notes or Preferred Shares, if any, or any interest therein, to any Competitor.
A Purchaser may rely on a representation from a potential Transferee (such
representation to be made for the benefit of such Purchaser and the Company)
that such Transferee is not a Competitor, and unless such Purchaser has actual
knowledge that such representation was untrue, such Transfer shall be valid.
As used herein, the term "Competitor" means (i) any Person (other than the
Company or any of its Subsidiaries) who is engaged in the Business and (ii)
any Affiliate of a Person identified in clause (i) above (it being agreed that
an investment firm shall not be deemed to control a Person described in clause
(i) above merely as a result of owning a minority interest in such Person).

7.6.          Transfers of Series A Preferred Shares and Series C Preferred
Shares.

              The transfer of the Series A Preferred Shares and the Series C
Preferred Shares shall be limited to the Affiliates of the Purchaser of such
shares hereunder. Except in the case of any sale, redemption or conversion of
the Notes in connection with a Series B Conversion Event, the Company shall
have the right to repurchase the Series A Preferred Shares upon (i) the sale or
redemption of sixty-five percent (65%) or more of the Common Stock Equivalents
held by such Purchaser as of the Second Closing Date or (ii) the conversion of
all of the Common Stock Equivalents held by such Purchaser. The Company shall
have the right to repurchase the Series C Preferred Shares upon (i) the sale or
redemption of sixty-five percent (65%) or more of the Common Stock Equivalents
held by such Purchaser as of the Second Closing Date or (ii) the conversion of
all of the Common Stock Equivalents held by such Purchaser.

hours, reasonable access, upon reasonable advance notice, to all of the books,
records and properties of the Company and its Subsidiaries and to all officers
and employees of the Company and its Subsidiaries; provided, however, that such
investigation shall not unreasonably interfere with the operations of the
Company and its Subsidiaries. The Company will instruct its independent public
accountants to discuss such aspects of the financial condition of the Company
with any Purchaser and its representatives as such Purchaser may reasonably
request, and to permit such Purchaser and its representatives to inspect, copy
and make extracts from such financial statements, analyses, work papers and
other documents and information (including electronically stored documents and
information) prepared by such accountants with respect to the Company as such
holder may reasonably request. All costs and expenses incurred by such
Purchaser and its representatives in connection with exercising such rights of
access shall be borne by such Persons, and all out-of-pocket costs and expenses
incurred by the Company in complying with any extraordinary requests by such
Purchaser and its representatives in connection with exercising such access
rights shall be borne by such Purchaser.

              (b)   Each Purchaser shall use reasonable efforts to maintain the
confidentiality of any confidential and proprietary information obtained by it
under this Section 8.1 and shall not use, or permit the use of, any of such
confidential and proprietary information in its business or the business of
any company in which it may have an ownership interest or in any manner or for
any other purpose except as contemplated hereby; provided, however, that the
foregoing shall in no way limit or otherwise restrict the ability of any
Purchaser or such authorized representatives to disclose any such information
concerning the Company which it may be required to disclose (i) to its
partners or limited partners to the extent required to satisfy its fiduciary
obligations to such persons or (ii) otherwise pursuant to or as required by
law; provided, however, it shall use reasonable efforts to cause its partners
or limited partners (as the case may be) to maintain the confidentiality of
such confidential and proprietary information.

              (c) As used herein, "Significant Holder" shall mean and include
any Purchaser who, at the time in question, shall own, together with its
Affiliates, (i) 25% of the aggregate principal amount of the outstanding Notes
or the number of Series D Preferred Shares purchased hereunder, or (ii) Series
B Preferred Shares, if any, convertible for, plus Warrants, if any,

period, together with a cumulative profit and loss statement from the first

                   (ii) a balance sheet as at the last day of such monthly
accounting period;

                   (iii) a cash flow analysis for such monthly accounting
period on a cumulative basis for the fiscal year to date; and

                   (iv) to the extent prepared by the Company prior to the
date of delivery of such monthly financial statements, a comparison between
the actual figures for such monthly accounting period and the comparable
figures for the prior year (if any) for such monthly accounting period, with
an explanation of any material differences between them.

              (c)   Quarterly Reports.  Upon the request of such Significant

prior fiscal year and the comparable budgeted figures for such prior fiscal

request, an explanation of any material differences between them; and

commencement of any action, suit, claim, legal or administrative or
arbitration proceeding or investigation, any of which could reasonably be
expected, on the basis of current economic conditions and other facts and
circumstances known to the Company at the time, to have a Material Adverse
Effect, the Company shall deliver a written notice to such Significant Holder
describing in reasonable detail such proceeding.

              paid when due, whether by acceleration or otherwise, or the
              holder of any Encumbrance upon property of the Company or any of
              its Subsidiaries shall commence foreclosure of such Encumbrance;

                            (vi) a material breach of any of the

              provided that if such default is not willful, such default
              continues 30 days after notice of such breach has been delivered
              by any holder of Note; or

                            (vii) a Change of Control shall have occurred;
              then, and in each and every such case (other than an Event of
              Default specified in clauses (ii) or (iii) above, the Requisite
              Purchasers, by notice in writing to the Company (the
              "Acceleration Notice"), may declare the entire principal amount
              of the Notes, and the interest accrued thereon, to be due and
              payable immediately, and the same shall become immediately due
              and payable without presentment, demand or protest, all of which
              are hereby expressly waived, anything contained herein or other
              evidence of such indebtedness to the contrary notwithstanding. If
              an Event of Default specified in clauses (ii) and (iii) occurs,
              the entire principal amount of this Note, and the interest
              accrued thereon, shall become and be immediately due and payable
              without any declaration or other act on the part of the
              Purchasers and the same shall become immediately due and payable
              without presentment, demand or protest, all of which are hereby

              such indebtedness to the contrary notwithstanding.

              (b)   In case any one or more Events of Default shall occur and
be continuing, the Holder may, inter alia, proceed to protect and enforce its
rights by an action at law, suit in equity or other appropriate proceeding,
whether for the specific performance of any agreement contained in this Note,
or for an injunction against a violation of any of the terms hereof or thereof
or in and of the exercise of any power granted hereby or thereby or by law. No
right conferred upon the Holder hereby shall be exclusive of any other right
referred to herein or now or hereafter available at law, in equity, by statute

                                  ARTICLE XI

                                 SUBORDINATION

11.1.         Notes Subordinated to Senior Debt.

              (a) The Company, for itself and its successors, and the
Purchaser, by its acceptance of the Notes, agrees that the payment of the
Subordinated Obligations is subordinated, to the extent and in the manner
provided in this Article, to the prior payment in full in cash of all Senior
Debt, including, with respect to Designated Senior Debt, any interest accruing
subsequent to a bankruptcy or other similar proceeding at the rate specified
in the applicable Designated Senior Debt whether or not such interest is an
allowed claim enforceable against the Company in any such proceeding.

              (b) This Article XI shall constitute a continuing offer to all
persons who, in reliance upon such provisions, become holders of, or continue
to hold, Senior Debt, and such provisions are made for the benefit of the
holders of Senior Debt, and such holders are made obligees hereunder and any
one or more of them may enforce such provisions. The provisions of this
Article shall be reinstated if at any time any payment of the Senior Debt is
rescinded or must otherwise be returned by any holder thereof or any
representative of such holder upon the insolvency, bankruptcy or
reorganization of the Company.

11.2.         No Payment on Notes in Certain Circumstances.

              (a) In the event that any payment of principal of or interest on
the Designated Senior Debt is not paid when due, whether at stated maturity,
by mandatory prepayment, by acceleration or otherwise (each, a "Senior Debt
Payment Default"), and the holders of Designated Senior Debt or their agent
shall have given written notice to the Company and the Purchaser of such
non-payment (a "Payment Default Notice"), then no payment shall be made by the
Company, or accepted by the Purchaser, on account of the Subordinated
Obligations unless and until such payment shall have been made or such Senior
Debt Payment Default is waived in accordance with the terms of the applicable
Senior Credit Documents.

              (b) In the event that any default under or in respect of the
Designated Senior Debt that entitles any holders of any Designated Senior Debt
to accelerate the maturity of such Designated Senior Debt outstanding
thereunder (other than a Senior Debt Payment Default) (each, a "Senior Debt
Non-Payment Default") shall have occurred and be continuing and the Company
and the Purchaser shall have received written notice of such Senior Debt
Non-Payment Default from the holders of any Designated Senior Debt or any
agent of such holders (a "Payment Blockage Notice"), then no payment shall be
made by the Company, or accepted by any Purchaser, on account of the
Subordinated Obligations during the period (a "Payment Blockage Period")
commencing on the date the Company and the Purchaser received such Payment
Blockage Notice and ending on the earlier of (i) the date 179 days thereafter
and (ii) the date on which the Senior Debt Non-Payment Default giving rise to
the Payment Blockage Period is cured or waived in accordance with the terms of
the applicable Senior Credit Documents; provided that (x) any holders of
Designated Senior Debt shall not be entitled to institute a Payment Blockage
Period more often than once within any period of 360 consecutive days, (y) no
Senior Debt Non-Payment Default or event which, with the giving of notice
and/or the lapse of time, would become a Senior Debt Non-Payment Default which
existed on the date of the commencement of any such blockage period may be
used as the basis for any subsequent Payment Blockage Notice unless such
Senior Debt Non-Payment Default or event, as the case may be, shall in the
interim have been cured or waived for a period of not less than ninety
consecutive days and (z) any holders of Designated Senior Debt shall not be
entitled to institute a Payment Blockage Period more than two times in total.

              (c) The failure to make any payment with respect to the
Subordinated Obligations by reason of the provisions of Section 11.2(a) or
(b), shall not be construed as preventing the occurrence of an Event of
Default hereunder or impairing the right to declare due and payable the
principal amount of and premium on the Notes, plus accrued but unpaid
interest, subject to Section 11.1.

              (d) In furtherance of the provisions of Section 11.1, in the
event that, notwithstanding the foregoing provisions of this Section 11.2, any
payment on account of principal of, premium, interest on the Notes or other
Subordinated Obligations or to acquire any of the Notes or on account of the
redemption provisions of the Notes shall be made by or on behalf of the Company
and received by any Purchaser at a time when such payment was prohibited by the
provisions of this Section 11.2, then, unless and until such payment is no
longer prohibited by this Section 11.2, such payment shall be received and held
in trust by such Purchaser for the benefit of, and, if any of the Senior Debt
remains outstanding, shall be immediately paid over to, either the Company or
the Senior Debtholders (or their representatives) ratably according to the
respective amounts of Senior Debt held or represented by each, for application
to the payment of all Senior Debt remaining unpaid to the extent necessary to
indefeasibly pay all Senior Debt in full in accordance with its terms, after
giving effect to any concurrent payment or distribution or provision therefor
to or for the Senior Debtholders.

              (e) The provisions of this Section 11.2 shall not apply to any
payment with respect to which Section 11.3 would be applicable.

11.3.         Notes Subordinated to Prior Payment of All Senior Debt on
Dissolution, Liquidation or Reorganization.

              Upon any payment or distribution of properties of the Company or
any successor in any dissolution, winding up, liquidation or reorganization of
the Company (including in bankruptcy, insolvency or receivership proceedings
or upon any assignment for the benefit of creditors, whether voluntary or
involuntary):

                            (i) The holders of all Senior Debt shall first be
              entitled to receive payments in full of all amounts due on or
              with respect to Senior Debt, including the principal, premium,
              and interest, fees, expenses and costs due thereon or relating
              thereto, including any interest accruing subsequent to a
              bankruptcy or other similar proceeding at the rate specified in
              the applicable Senior Debt whether or not such interest is an
              allowed claim enforceable against the Company in any such
              proceeding, before the Purchaser is entitled to receive any
              payment or distribution in cash, securities or other Property on
              account of the Subordinated Obligations (other than any payment
              or distribution in the form of securities, including, without
              limitation, Common Stock Equivalents, the payment of which (i) is
              subordinated in right of payment to all Senior Debt that may at
              the time be outstanding to the same extent as, or to a greater
              extent than, the Subordinated Obligations are subordinate to the
              Senior Debt as provided in this Article and (ii) is not payable
              prior to the payment in full of the Senior Debt).

                            (ii) Any payment or distribution, whether in cash,
              cash equivalents, property or securities, to which the Purchaser
              would be entitled except for the provisions of this Article,
              shall be paid by the liquidating trustee or agent or other
              person making such a payment or distribution, directly to the
              holders of Senior Debt (or their representatives) ratably
              according to the respective amounts of Senior Debt held or
              represented by each, to the extent necessary to make payment in
              full in cash of all Senior Debt remaining unpaid after giving
              effect to any concurrent payment or distribution or provision
              therefor to the holders of such Senior Debt.

                            (iii) In the event that, notwithstanding the
              foregoing, any payment or distribution, whether in cash, cash
              equivalents property or securities (other than any payment or
              distribution in the form of securities, including, without
              limitation, Common Stock Equivalents, the payment of which (i)
              is subordinated in right of payment to all Senior Debt that may
              at the time be outstanding to the same extent as, or to a
              greater extent than, the Subordinated Obligations are
              subordinate to the Senior Debt as provided in this Article and
              (ii) is not payable prior to the payment in full of the Senior
              Debt), shall be received by the Purchaser on account of the
              Subordinated Obligations before all Senior Debt is indefeasibly
              paid in full in cash, such payment or distribution shall be
              received and held in trust by such Purchaser for the benefit of,
              and shall be immediately paid over to the Senior Debtholders (or
              their representatives) which remain unpaid or unprovided for,
              ratably according to the respective amounts of the Senior Debt
              held or represented by each, for application to the payment of
              all Senior Debt remaining unpaid to the extent necessary to
              indefeasibly pay all Senior Debt in full in accordance with its
              terms, after giving effect to any concurrent payment or
              distribution or provision therefor to or for the Senior
              Debtholders.

11.4.         Payments Otherwise Permitted.

              Nothing contained in any Document shall prevent the Company, at
any time except during any dissolution, liquidation, winding up, or
reorganization of the Company referred to in Section 11.3 or under the
conditions described in Section 11.2, from making payments at any time with
respect to the Subordinated Obligations.

11.5.         Subrogation.

              Subject to the payment in full in cash of all Senior Debt and
the termination of all commitments to advance additional funds to the Company
pursuant to the Senior Credit Documents, the Purchaser shall be subrogated to
the rights of the Senior Debtholders to receive payments or distributions of
properties of the Company applicable to the Senior Debt until all amounts due
and payable on the Notes and all other Subordinated Obligations shall be paid
in full. For the purpose of such subrogation, no payments or distributions to
the Senior Debtholders by or on behalf of the Company, or by or on behalf of
the Purchaser by virtue of this Article, which otherwise would have been made
to the Purchaser shall, as between the Company, its creditors other than the
Senior Debtholders and the Purchaser, be deemed to be payment by the Company
to or on account of the Senior Debt, it being understood that the provisions
of this Article are, and are intended, solely for the purpose of defining the
relative rights of the Purchaser, on the one hand, and Senior Debtholders, on
the other hand.

11.6.         Obligations of the Company Unconditional.

              Nothing contained in this Article or elsewhere in this Agreement
or in any Note is intended to or shall impair, as between the Company, its
creditors (other than the Senior Debtholders) and the Purchaser, the
obligations of the Company, which are absolute and unconditional, to pay to
the Purchaser the Subordinated Obligations when the same become due and
payable in accordance with their terms, or is intended to or shall affect the
relative rights of the Purchaser and creditors of the Company other than the
Senior Debtholders, nor shall anything herein or therein prevent any Purchaser
from exercising all remedies otherwise permitted by Applicable Law upon
default under this Agreement, subject to the rights, if any, and the
limitations on remedies provided in this Article (including Section 11.9), of
the holders of Senior Debt. Notwithstanding anything to the contrary in this
Agreement or in the Notes, upon any distribution of properties of the Company
referred to in this Article, the Purchaser shall be entitled to rely upon any
judgment made by any court of competent jurisdiction in which such
dissolution, winding up, liquidation or reorganization proceedings are
pending, or a certificate of the liquidating trustee or agent or other person
making any distribution to the Purchaser, for the purpose of ascertaining the
persons entitled to participate in such distribution, the Senior Debtholders
and other Obligations of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article.

11.7.         Subordination Rights Not Impaired by Acts or Omissions of the
Company or Senior Debtholders.

              No right of any present or future holders of any Senior Debt to
enforce subordination as provided in this Article shall at any time in any way
be prejudiced or impaired by any act or failure to act on the part of the
Company or by any noncompliance by the Company with the terms of this
Agreement, regardless of any knowledge thereof which any such holder may have
or otherwise be charged with. Subject to the limitations as set forth in the
definition of Senior Debt, the holders of Senior Debt may, without notice to
or consent of any Purchaser, extend, renew, modify, amend or supplement the
terms of the Senior Debt (including changing the terms of payment, or the
refinancing or restructuring of such Senior Debt) or any security received in
exchange therefor and release, sell security or release any persons in any
manner liable for such Obligations and otherwise deal freely with the Company,
all without affecting the Obligations of the Company or the Purchaser under
this Agreement.

11.8.         Notice to Purchaser.

              Notwithstanding the provisions of this Article or any other
provision of this Agreement, the Purchaser shall not be charged with knowledge
of the existence of any facts that would prohibit the making of any payment in
respect of the Subordinated Obligations (including notification of the
existence or designation of Designated Senior Debt), unless and until the
Purchaser shall have actual knowledge thereof; and, prior to the receipt of
any written notice thereof from the Company or a Senior Debtholder or from any
trustee, fiduciary or agent therefor, the Purchaser shall be entitled in all
respects to assume that no such facts exist. The Purchaser shall be entitled
to rely on the delivery to it of a written notice by a Person representing
itself to be a Senior Debtholder (or a trustee, fiduciary or agent therefor).
In the event that the Purchaser determines in good faith that further evidence
is required with respect to the right of any Person as a Senior Debtholder to
participate in any payment or distribution pursuant to this Article, the
Purchaser may request such Person to furnish evidence to the reasonable
satisfaction of the Purchaser as to the amount of Senior Debt held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article and if such evidence is not furnished, the Purchaser
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.

11.9.         Limitations on Remedies.

              (a) Notwithstanding anything contained herein to the contrary,
during any period commencing on the date of receipt of a Payment Default Notice
under Section 11.2(a) or a Payment Blockage Notice under Section 11.2(b) and
ending on the earlier of (i) the date the default that is the subject of such
Payment Default Notice or Payment Blockage Notice, as the case may be, is cured
or waived or (ii) ninety days after receipt by the Purchaser of such Payment
Default Notice or 360 days after receipt by the Purchaser of such Payment
Blockage Notice, the Purchaser shall not (i) accelerate the Notes as provided
in Section 10.1, (ii) initiate any judicial proceeding or action to collect the
Notes or (iii) initiate any case, proceeding or other action in respect of the
Company or its Subsidiaries of the type referred to in clause (a) or (b) of
Section 11.3 unless, prior to the expiration of such period, (x) any holder of
Designated Senior Debt or its agent shall take any action of the type referred
to in clauses (i), (ii) and (iii) above in respect of Designated Senior Debt or
(y) any Senior Debt shall have become automatically due and payable in
accordance with its terms.

              (b) Prior to taking any action of the type referred to in
clauses (i), (ii) and (iii) of Section 11.9(a), the Purchaser shall give the
Agent, no less than 20 days' notice of the Purchaser's intent to take any such
action (which notice may be given during the continuation of any period during
which the Purchaser is blocked from receiving payments under Section 11.2).

                                  ARTICLE XII

                                 MISCELLANEOUS

12.1.         Termination Events.

              In the event the First Closing contemplated under this Agreement
shall not have occurred on or before June 12, 1998, this Agreement may be
terminated by CVCA or the Company; provided however, that the right to
terminate this Agreement pursuant to this Section 12.1 shall not be available
to either of the respective parties whose failure to fulfill any obligation
under this Agreement has been the cause of, or resulted in, the failure of the
Closing to occur on or before such date.

12.2.         Exchange of Notes.

              Prior to a Series B Preferred Conversion Event, in the event the
Company consummates a reorganization pursuant to which a holding company
("Newco") is created which owns all of the outstanding stock of the Company,
then the Company and the Purchaser shall enter into an exchange agreement, in a
form reasonably acceptable to the Requisite Purchasers and the Agent, pursuant
to which the Purchased Notes will be exchanged for convertible notes (the
"Exchanged Notes"), of Newco, which Exchanged Notes shall be economically
identical to the Purchased Notes, including its rights, privileges and
benefits, and shall be otherwise in a form and substance reasonably acceptable
to the Purchaser. The conditions of such exchange shall include the following:
(i) a Default shall not have occurred and be continuing; (ii) the exchange
shall qualify as a tax-free exchange under the Code; (iii) the Exchanged Notes
shall be governed by and entitled to all the benefits of this Agreement (as if
such Exchanged Notes were issued on the Closing Date pursuant to the terms of
this Agreement); (iv) in the case of any Purchaser acquiring Purchased Notes on
a Closing Date, for purposes of determining the applicable holding period for
such Purchased Notes under Rule 144(d), the Exchanged Notes shall be deemed to
have been acquired at the Closing at which such Notes were purchased; (v) legal
counsel to the Company shall deliver a legal opinion addressed to the
Purchasers, dated as of the date of such exchange, in a form reasonably
acceptable to the Requisite Purchasers; and (vi) the Company and Newco shall
covenant to the Purchasers that (x) at no time shall the Company cease to be a
wholly-owned subsidiary of Newco and (y) neither the Company nor Newco shall
enter into any agreement which would restrict the Company's ability to pay
dividends or make any other distributions to Newco.

12.3.         Fees.

              (a) The Company will pay, and save the Purchasers harmless
against all Liability, whether or not the Closing hereunder occurs, for the
payment of, (i) all costs and other expenses incurred from time to time by the
Company in connection with the Company's performance of and compliance with
all agreements and conditions contained herein on its part to be performed or
complied with (including the reasonable costs and expenses of counsel incurred
in connection with the review and preparation of the Documents), (ii) the
actual and reasonable out-of-pocket costs and expenses incurred by the
Purchasers at or prior to closing in connection with the transactions
contemplated hereby, including reasonable fees and charges of O'Sullivan Graev
& Karabell, LLP (counsel to the Purchasers), and Arthur Andersen, LLP
(accountant to the Purchasers), in connection with the purchase and ownership
of the Purchased Notes and Preferred Shares, provided however, that the
Company's reimbursement obligations under this clause (ii) shall not exceed
$100,000 unless approved by the Company, (iii) the reasonable costs and
expenses (including fees and expenses of counsel) incurred by the Purchasers
in connection with any amendment or waiver of, or enforcement of, any Document
relating to the transactions contemplated hereby, and (iv) the reasonable fees
and expenses incurred by each Purchaser in any filing with any Governmental
Authority with respect to its investment in the Company or in any other filing
with any Governmental Authority with respect to the Company that mentions such
Purchaser.

              (b) The Company further agrees that it will pay, and will save
the Purchasers harmless from, any and all Liability with respect to any stamp
or similar taxes which may be determined to be payable in connection with the
execution and delivery and performance of the Documents or any modification,
amendment or alteration of the terms or provisions of the Documents, and that
it will similarly pay and hold the Purchasers harmless from all issue taxes in
respect of the issuance of the Additional Notes or Reserved Common Shares to
the Purchasers.

12.4.         Further Assurances.

              The Company shall duly execute and deliver, or cause to be duly
executed and delivered, at its own cost and expense, such further instruments
and documents and to take all such action, in each case as may be necessary or
proper in the reasonable judgment of the Purchasers to carry out the provisions
and purposes of the Agreement and the other Documents.

12.5.         Remedies.

              In case any one or more of the representations, warranties,
covenants and/or agreements set forth in this Agreement shall have been
breached by the Company, the Purchasers (or any Purchaser) may proceed to
protect and enforce its or their rights either by suit in equity and/or by
action at law, including an action for damages as a result of any such breach
and/or an action for specific performance of any such covenant or agreement
contained in this Agreement.

12.6.         Successors and Assigns.

              This Agreement shall bind and inure to the benefit of the
Company and the Purchasers and their respective successors, assigns, heirs and
personal representatives. Upon any transfer of the Notes or the Reserved
Common Shares, the transferee shall be bound by, and entitled to the benefits
of, this Agreement with respect to such transferred Securities in the same
manner as the transferring Purchaser.

12.7.         Entire Agreement.

              This Agreement and the other writings referred to herein or
delivered pursuant hereto which form a part hereof contain the entire
agreement among the parties with respect to the subject matter hereof and
thereof and supersede all prior and contemporaneous arrangements or
understandings with respect thereto.

12.8.         Notices.

              All notices and other communications delivered hereunder
(whether or not required to be delivered hereunder) shall be deemed to be

next Business Day after dispatch, if sent by nationally recognized, overnight
courier guaranteeing next Business Day delivery, and (iv) on the fifth

12.9.         Amendments, Modifications and Waivers.

              The terms and provisions of this Agreement may not be modified
or amended, nor may any of the provisions hereof be waived, temporarily or
permanently, except pursuant to a written instrument executed by the Company
and the Requisite Purchasers and in the case of amendments, modifications or
waivers of provisions of Article XI, definitions of capitalized terms used in
Article XI, or Section 12.2 or this Section 12.9, with the consent of the
Agent; provided however that any such amendment, modification or waiver that
would adversely affect the rights hereunder of any Purchaser, in its capacity
as a Purchaser, without similarly affecting the rights hereunder of all
Purchasers, in their capacities as Purchasers, shall not be effective as to
such Purchaser without its prior written consent.

12.10.        Governing Law; Waiver of Jury Trial.

              (a) All questions concerning the construction, interpretation
and validity of the Documents shall be governed by and construed and enforced
in accordance with the domestic laws of the State of New York, without giving
effect to any choice or conflict of law provision or rule (whether in the
State of New York or any other jurisdiction) that would cause the application
of the laws of any jurisdiction other than the State of New York. In
furtherance of the foregoing, the internal law of the State of New York will
control the interpretation and construction of the Documents, even if under
such jurisdiction's choice of law or conflict of law analysis, the substantive
law of some other jurisdiction would ordinarily or necessarily apply.

              (b) BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX
FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN
EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE LAWS TO APPLY
(RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR DISPUTES BE
RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE
BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION,
THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT OR
PROCEEDING BROUGHT TO ENFORCE OR DEFEND ANY RIGHTS OR REMEDIES UNDER THIS
AGREEMENT OR ANY DOCUMENTS RELATED HERETO.

12.11.        No Third Party Reliance.

              Anything contained herein to the contrary notwithstanding, the
representations and warranties of the Company contained in this Agreement (a)
are being given by the Company as an inducement to the Purchasers to enter
into this Agreement and the other Documents (and the Company acknowledges that
the Purchasers have expressly relied thereon) and (b) are solely for the
benefit of the Purchasers. Accordingly, no third party (including, without
limitation, any holder of capital stock of the Company) or anyone acting on
behalf of any thereof other than the Purchasers, and each of them, shall be a
third party or other beneficiary of such representations and warranties and no
such third party shall have any rights of contribution against the Purchasers
or the Company with respect to such representations or warranties or any matter
subject to or resulting in indemnification under this Agreement or otherwise.

12.12.        Submission to Jurisdiction.

              Any legal action or proceeding with respect to this Agreement or
the other Documents may be brought in the courts of the State of New York and
the United States of America for the Southern District of New York and, by
execution and delivery of this Agreement, the Company hereby accepts for itself
and in respect of its property, generally and unconditionally, the jurisdiction
of the aforesaid courts. The Company hereby irrevocably waives, in connection
with any such action or proceeding, any objection, including, without
limitation, any objection to the venue or based on the grounds of forum non
conveniens, which it may now or hereafter have to the bringing of any such
action or proceeding in such respective jurisdictions. The Company hereby
irrevocably consents to the service of process of any of the aforementioned
courts in any such action or proceeding by the mailing of copies thereof by
registered or certified mail, postage prepaid, to it at its address as set
forth herein. Nothing herein shall affect the right of the Purchasers to serve
process in any other manner permitted by law or to commence legal proceedings
or otherwise proceed against the Company in any other jurisdiction.

12.13.        Extension; Waiver.

              At any time prior to the First Closing, the parties may (a)
extend the time for the performance of any of the obligations or other acts of
the other parties, (b) waive any inaccuracies in the representations and
warranties contained in this Agreement or in any document delivered pursuant
to this Agreement and (c) waive compliance with any of the agreements or
conditions contained in this Agreement. Any agreement on the part of a party
to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party, and any such waiver
shall not operate or be construed as a waiver of any subsequent breach by the
other party.

12.14.        Severability.

              It is the desire and intent of the parties that the provisions of
this Agreement be enforced to the fullest extent permissible under the law and
public policies applied in each jurisdiction in which enforcement is sought.
Accordingly, in the event that any provision of this Agreement would be held in
any jurisdiction to be invalid, prohibited or unenforceable for any reason,
such provision, as to such jurisdiction, shall be ineffective, without
invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of such provision in any jurisdiction.
Notwithstanding the foregoing, if such provision could be more narrowly drawn
so as not be invalid, prohibited or unenforceable in such jurisdiction, it
shall, as to such jurisdiction, be so narrowly drawn, without invalidating the
remaining provisions of this Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction.

12.15.        Independence of Agreements, Covenants, Representations and
Warranties.

              All agreements and covenants hereunder shall be given independent
effect so that if a certain action or condition constitutes a default under a
certain agreement or covenant, the fact that such action or condition is
permitted by another agreement or covenant shall not affect the occurrence of
such default, unless expressly permitted under an exception to such initial
covenant. In addition, all representations and warranties hereunder shall be
given independent effect so that if a particular representation or warranty
proves to be incorrect or is breached, the fact that another representation or
warranty concerning the same or similar subject matter is correct or is not
breached will not affect the incorrectness of or a breach of a representation
and warranty hereunder. The exhibits and schedules attached hereto are hereby
made part of this Agreement in all respects. Any disclosure made in any
Schedule to this Agreement which should, based on the substance of such
disclosure, be applicable to another Schedule to this Agreement shall be deemed
to be made with respect to such other Schedule regardless of whether or not a
specific reference is made thereto; provided, that the description of such item
on a Schedule is such that the Purchaser could reasonably be expected to
ascertain that such disclosure would relate to such other provision of this
Agreement.

12.16.        Counterparts; Facsimile Signatures.

              This Agreement may be executed in any number of counterparts,
and each such counterpart hereof shall be deemed to be an original instrument,
but all such counterparts together shall constitute but one agreement.
Facsimile counterpart signatures to this Agreement shall be acceptable an
binding.

                                   * * * *


              IN WITNESS WHEREOF, the parties hereto have executed this
Securities Purchase Agreement as of the date first above written.

              The Corporation shall not, without the affirmative consent or
approval of the Requisite Preferred Holders:

                (i) in any manner authorize, issue or sell any shares of
          Series A Preferred Stock other than as contemplated by the
          Purchase Agreement or this Article IX;

               (ii) reclassify, cancel or in any manner alter or change the
          terms, designations, powers, preferences or relative, optional or

          restrictions thereof, of the Series A Preferred Stock;

          IX; or

               (iv) amend, repeal or modify any provision of the Certificate
          of Incorporation or By-laws in a manner that would adversely
          affect the powers, preferences or rights of the Series A
          Preferred Stock.

          (d) Observer Rights.

          (i) The Corporation hereby covenants that the Preferred Holders
shall have the right to have that number of representatives (each such
representative, an "Observer") determined as hereinafter provided present at
all meetings of the Board. Such right shall from time to time be exercisable
by delivery to the Corporation of written notice from the Requisite Preferred
Holders specifying the names of such Observers. The number of Observers shall
at all times and from time to time be equal to that number of members of the
Board that the Preferred Holders are then entitled to designate but whose
seats on the Board are at the time vacant.

          (ii) The Corporation will give each Observer reasonable prior notice
(it being agreed that the same prior notice given to the Board shall be deemed
reasonable prior notice) in any manner permitted in the Corporation's By-laws
for notices to directors of the time and place of any proposed meeting of the
Board, such notice in all cases to include true and complete copies of all
documents furnished to any director in connection with such meeting. Each such
Observer will be entitled to be present in person as an observer at any such
meeting or, if a meeting is held by telephone conference, to participate
therein for the purpose of listening thereto.

         (iii) The Corporation will deliver to each Observer copies of all
papers which may be distributed from time to time to the directors of the
Corporation at such time as such papers are so distributed to them, including
copies of any written consent.

       4. Liquidation.

          In the event of any Liquidation, the Preferred Holders shall be
entitled to receive, out of the assets of the Corporation legally available for
distribution to its stockholders, before any payment shall be made to the
holders of any stock ranking on Liquidation junior to the Series A Preferred
Stock (with respect to rights on Liquidation, the Series A Preferred Stock
shall rank senior to the Common Stock, pari passu with the Series C Preferred
Stock but junior to all other series of Preferred Stock), an amount per share
equal to (the "Preferred Liquidation Preference") the Original Cost of such
share. If, upon any Liquidation, the assets of the Corporation available for
distribution to its stockholders shall be insufficient to pay the Preferred
Holders the full amount to which it shall be entitled, then the Corporation
shall pay the Preferred Holders the aggregate unpaid Preferred Liquidation
Preference as soon as practicable after the Corporation has funds legally
available therefor. In the event of any Liquidation, after payment shall have
been made to the Preferred Holders in the full amount to which it is entitled,
the holders of shares of Common Stock shall be entitled, to the exclusion of
the Preferred Holders, to share, according to their respective rights and
preferences, in all remaining assets of the Corporation available for
distribution to its stockholders.

       5. Redemption.

          (a) Subject to the Corporation having funds legally available for
such purpose, the Corporation shall redeem all of the shares of the Series A
Preferred Stock then outstanding, on the first to occur of (A) on the Maturity
Date, so long as all of the outstanding Notes, the outstanding shares of the
Series B Preferred Stock and the outstanding shares of the Series D Preferred
Stock shall have been redeemed or converted prior thereto, (B) upon the
occurrence of the Mandatory Conversion Event, or (C) in the event a Series A
Preferred Redemption Event shall have occurred (each of clauses (A), (B) and
(C) above, a "Redemption Event"). The per share redemption price at which
shares of Series A Preferred Stock are to be redeemed pursuant to this Section
5(a) shall be equal to the Liquidation Preference Amount (the "Redemption
Price").

          (b) On and after any redemption date (the "Redemption Date")
pursuant to this Section 5 (unless default shall be made by the Corporation
in the payment of the Redemption Price, in which event such rights shall be
exercisable until such default is cured), all rights in respect of the
shares of the Series A Preferred Stock to be redeemed, except the right to
receive the Redemption Price, shall cease and terminate, and such shares
shall no longer be deemed to be outstanding, whether or not the
certificates representing such shares have been received by the
Corporation.

          (c) Any communication or notice relating to redemption given pursuant
to this Section 5 shall be sent by first-class certified mail, return receipt
requested, postage prepaid, to the Preferred Holders, at their respective
addresses as the same shall appear on the books of the Corporation, or to the
Corporation at the address of its principal, or registered office, as the case
may be.

          (d) At any time on or after the Redemption Date, the Preferred Holders
shall be entitled to receive the Redemption Price upon actual delivery to the
Corporation or its agents of the certificates representing the shares of the
Series A Preferred Stock to be redeemed.

          (e) Any redemption payments by the Corporation pursuant to this
Section 5 shall be paid in cash.

          (f) Any shares of Series A Preferred Stock which are redeemed,
converted or otherwise acquired by the Corporation shall be canceled and
shall not be reissued (as treasury shares), sold or transferred as Series A
Preferred but such shares shall become unclassified Preferred Stock of the
Corporation.

       4. Dividends, Distributions and Liquidations.

          (a) Dividends.

              (i) When, as, and if declared by the Board, out of funds
legally available for that purpose, the holders of Series B Preferred Stock
shall be entitled to receive before any dividends shall be declared and
paid or set aside for Common Stock, dividends, which shall accrue on a
daily basis at the Applicable Dividend Rate on the sum of the Original Cost
of a share of Series B Preferred Stock, plus all accumulated and unpaid
dividends thereon, payable on each September 30 and March 31 (each, a
"Preferred Dividend Payment Date"), the first such Preferred Dividend
Payment Date being the first Preferred Dividend Payment Date following the
Series B Conversion Event. Dividends shall accrue at the Applicable
Dividend Rate regardless of whether the Board has declared a dividend
payment or whether there are any profits, surplus or other funds of the
Corporation legally available for dividends. Any dividends which accrue
pursuant to this Section 4(a) and which are not paid prior to the next
succeeding Preferred Dividend Payment Date shall be classified as
"accumulated dividends" and shall remain "accumulated and unpaid dividends"
until paid or otherwise satisfied pursuant to this Article X. Dividends on
each share of Preferred Stock shall accrue pursuant to this Section 4(a)
from and including the Original Issuance Date to and including the date
such share is converted or redeemed in full and all accrued but unpaid
dividends thereon are also converted or paid in full. All payments in cash
due in cash under this Section 4(a) to any holder of shares of Series B
Preferred Stock shall be made to the nearest cent.

             (ii) The dividends payable with respect to the Series B Preferred
Stock on each Preferred Dividend Payment Date shall be paid to the holders
of shares of the Preferred Stock as they appear on the stock records of the
Corporation on such date (the "Preferred Record Date") as shall be fixed by
the Board, which Preferred Record Date shall not be more than 60 days prior
to the applicable Preferred Dividend Payment Date and shall not precede the
date upon which the resolution fixing such Preferred Record Date is
adopted, and if the Board shall not fix a Preferred Record Date, the
Preferred Record Date shall be deemed to be the same date as the applicable
Preferred Dividend Payment Date.

             (iii) Except as otherwise provided herein, if at any time the
Corporation pays less than the total amount of dividends then accrued with
respect to the Series B Preferred Stock, such payment shall be distributed
ratably among the holders of the Series B Preferred Stock based upon the
number of shares of Series B Preferred Stock then held by each holder.

          (b) Liquidation.

          In the event of any Liquidation, the holders of shares of Series B
Preferred Stock then outstanding shall be entitled to receive, out of the
assets of the Corporation legally available for distribution to its
stockholders, before any payment shall be made to the holders of any stock
ranking on Liquidation junior to the Series B Preferred Stock (with respect to
rights on Liquidation, the Series B Preferred Stock shall rank senior to the
Common Stock and any other class of Junior Stock), an amount per share equal
to (the "Preferred Liquidation Preference") the greater of (X) the Original
Cost of such share plus an amount equal to any accumulated and unpaid
dividends on each share to the date of payment or (Y) the amount that would
otherwise be distributed to such holder in such Liquidation if nothing was
paid pursuant to clause (X) and such holder converted such shares into shares
of Common Stock in accordance with the provisions of this Article X. If, upon
any Liquidation, the assets of the Corporation available for distribution to
its stockholders shall be insufficient to pay the holders of shares of the
Series B Preferred Stock the full amounts to which they respectively shall be
entitled, the holders of shares of Series B Preferred Stock shall share
ratably in any distribution of assets according to the respective amounts
which would be payable with respect to the shares held by them upon such
distribution if all amounts payable on or with respect to said shares were
paid in full. In the event of any Liquidation, after payment shall have been
made to the holders of shares of Series B Preferred Stock in the full amount
to which they are entitled, the holders of shares of capital stock ranking
junior to the Series B Preferred Stock on Liquidation shall be entitled, to
the exclusion of the holders of the Series B Preferred Stock, to share,
according to their respective rights and preferences, in all remaining assets
of the Corporation available for distribution to its stockholders.

       5. Redemption.

          (a)  Mandatory Redemption.

          Subject to the Corporation having funds legally available for such
purpose, the Corporation shall redeem all of the shares of the Series B
Preferred Stock then outstanding on the Mandatory Redemption Date. The per
share redemption price (the "Mandatory Redemption Price") at which shares of
the Series B Preferred Stock are to be redeemed pursuant to this Section 5(a)
shall be equal to the greater of (x) the Original Cost of such share plus an
amount equal to any accumulated and unpaid dividends on each share, if any, to
the date of payment or (y) the Fair Value of such share. If the funds of the
Corporation legally available for redemption of shares of Series B Preferred
Stock shall be insufficient to permit the payment of the Mandatory Redemption
Price required to be paid pursuant to this Section 5(a), then the holders of
Series B Preferred Stock shall share in any legally available funds ratably in
any such redemption based on the respective number of Series B Preferred Stock
that each holder thereof holds and the Corporation shall redeem the remaining
shares to have been redeemed as soon as practicable after the Corporation has
funds legally available therefor.

          (b) Redemption at the Option of the Holders.

              (i) At any time on or after the occurrence or continuation of
an Event of Default, the Requisite Preferred Holders may elect to have the
Corporation redeem all (but not less than all) of the outstanding shares of
Series B Preferred Stock at a price per share (i) in the case of a
redemption option caused by an Event of Default, other than a Change of
Control, equal to the Original Cost of such share plus an amount equal to
all accrued and unpaid dividends on each share, if any, to the date of
payment and (ii) in the case of a Change of Control (the "Change of Control
Price"), equal to 101% of the Original Cost thereof plus, without
duplication, an amount in cash equal to accrued and unpaid dividends
thereof (in either case, the "Redemption Price"), by giving written notice
to the Corporation of such election (the "Investor Notice of Election"),
whereupon the Corporation shall be obligated to repurchase such shares of
Series B Preferred Stock on such date (the "Investor Optional Redemption
Date") as shall be determined by the Corporation, but in any event not
earlier than 10 days and not later than 30 days after the date on which the
Investor Notice of Election is delivered to the Corporation. Promptly (but
in no event later than five days) after the delivery of the Investor Notice
of Election to the Corporation, the Corporation shall send written notice
(the "Optional Redemption Notice") to each of the holders of the Series B
Preferred Stock. The Optional Redemption Notice shall specify the Investor
Optional Redemption Date and the location of the Corporation's principal
executive office or place of business where the closing will occur.

       (ii) Closing.

                (A) The closing of the Corporation's redemption of the Series
            B Preferred Stock pursuant to Section 5(c) above shall take
            place at 11:00 a.m. New York City time on the Investor
            Optional Redemption Date at the Corporation's principal
            executive office or place of business. At the closing, the
            Corporation shall pay to each of the holders of the Series B
            Preferred Stock, against the Corporation's receipt from such
            holder of the certificate or certificates representing the
            shares of such series of Series B Preferred Stock then held by
            such holder, an amount equal to the Redemption Price. All such
            payments shall be made by wire transfer of immediately
            available funds, or if such holder shall not have specified
            wire transfer instructions to the Corporation prior to the
            closing, by certified or official bank check made payable to
            the order of such holder.

                (B) If the funds of the Corporation (without rendering the
            Corporation insolvent) available for redemption of shares of
            Series B Preferred Stock on any Investor Redemption Date are
            insufficient to redeem the total number of such shares to be
            redeemed on such date, those funds which are legally available
            (without rendering the Corporation insolvent) shall be used to
            redeem the maximum possible number of shares ratably among the
            holders of such shares based upon the aggregate number of such
            shares held by each such holder. At any time thereafter when
            additional funds of the Corporation are legally available which
            will not make the Corporation insolvent for the redemption of
            shares such funds shall immediately be used to redeem the
            balance of the shares which the Corporation has become
            obligated to redeem on any Investor Redemption Date but which
            it had not redeemed.

          (c) Redemption at the Option of the Corporation.

              The Series B Preferred Stock is redeemable at the option of the
Corporation, in whole or in part at a per share price equal to the Original
Cost of such share plus any accrued but unpaid dividends on each share, if
any, to the date of payment; provided however, that in the event the
Corporation shall redeem all or any portion of the shares of the outstanding
Series B Preferred Shares, then the Holder shall be entitled to receive a
warrant (the "Warrant") that is initially exercisable for that number of
shares of Common Stock equal to the number of shares of Common Stock,
including the accrued but unpaid dividends thereon, into which such redeemed
shares would have been convertible in the event of an optional conversion at
such time pursuant to Section 6(a) hereof, of the shares redeemed hereunder
immediately prior to such redemption; provided, further, however, that in the
event the Series B Preferred Shares shall be redeemed by the Corporation in
connection with a Change of Control the amount paid by the Corporation to the
holder in connection with such prepayment shall equal the Change of Control
Price. The initial exercise price for each share of Common Stock issuable upon
exercise of the Warrant shall be equal to the Conversion Price in effect
immediately prior to the prepayment. The Warrant shall have customary cashless
conversion and exercise provisions, customary anti-dilution protections
economically identical to the Series B Preferred Stock and shall otherwise be
in form and substance reasonably acceptable to the holder of such shares.

          (d) General

              (i) No shares of Series B Preferred Stock are entitled to any
dividends accumulating after the date on which the full redemption price
for such share is paid to the holder thereof. On such date all rights of
the holder of such share shall cease, and such share shall not be deemed to
be outstanding.

             (ii) Any shares of Series B Preferred Stock which are redeemed or
otherwise acquired by the Corporation shall be canceled and shall not be
reissued (as treasury shares), sold or transferred.

            (iii) Neither the Corporation nor any Subsidiaries shall offer to
purchase, redeem or acquire any shares of Series B Preferred Stock other than
pursuant to the terms of this Article X or pursuant to a purchase offer made
to all holders of Series B Preferred Stock pro rata based upon the number of
such shares owned by such holders.

       6. Conversion.

          (a) Optional Conversion of Series B Preferred Stock into Common
Stock.

              Subject to and in compliance with the applicable provisions of
this Article X, each holder of shares of Series B Preferred Stock shall
have the right, at such holder's option, at any time and from time to time,
to convert any such share, or the accumulated and unpaid dividends accrued
thereon, into that number of fully paid and nonassessable shares of Common
Stock (provided that in such event the holder shall have the option to
require that such shares be Qualified Securities) equal to the quotient
obtained by dividing (x) the sum of the Original Cost of such shares of
Series B Preferred Stock, plus all accumulated and unpaid dividends
thereon, by (y) the Conversion Price, as last adjusted and then in effect,
by surrender of the certificates representing such share to be converted;
provided however, that the Preferred Holder shall have the right to convert
all or a portion of the accumulated and unpaid dividends on any share of
Series B Preferred Stock without the need to convert the share of Series B
Preferred Stock on which such dividends accrued. The Corporation shall
give the Preferred Holders reasonable prior notice of a Sale of the
Corporation, including the price and material terms and conditions thereof,
in order to provide the Preferred Holders reasonable opportunity to
consider whether to redeem or convert the Series B Preferred Stock, or the
accumulated and unpaid dividends accrued thereon, into Common Stock at or
prior to such Sale of the Corporation. If the price or material terms or
conditions of such transaction thereafter change, the Corporation shall
promptly deliver written notice to the Preferred Holders specifying such
changes. The Corporation will not issue fractional shares of its Common
Stock, as applicable, and shall distribute cash in lieu of such fractional
shares.

          (b) Mandatory Conversion of Series B Preferred Stock into Common
Stock.

              Upon the occurrence of a Mandatory Conversion Event, all shares
of Series B Preferred Stock then outstanding shall, at the option of the
Corporation by virtue of the delivery of a notice by the Corporation to the
holder notifying the holder of the occurrence of such Mandatory Conversion
Event, which notice shall state the date upon which such conversion shall
become effective (the "Effective Date") (which date shall be no earlier than
15 Business Days after the date of delivery), and without any action on the
part of the holders thereof, shall on the Effective Date be deemed
automatically converted in accordance with and subject to prior compliance
with Section 6(c)(ii) into that number of fully paid and nonassessable shares
of Qualified Securities into which such shares, including the accumulated and
unpaid dividends accrued thereon, would have been convertible in the event of
optional conversion at such time pursuant to subsection (a) above. Upon
conversion, the Corporation will not issue fractional shares of its Qualified
Securities, as applicable, and shall distribute cash in lieu of such
fractional shares.

          (c) Conversion Price Adjustment.

              (i) The Conversion Price shall also be subject to adjustment
from time to time as follows:

                 (A)  If the Corporation shall, at any time or from time to
            time after the Original Issuance Date, issue any shares of Common
            Stock (other than Excluded Stock) without consideration or for a
            consideration per share less than the Adjusted Market Price in
            effect immediately prior to the issuance of such Common Stock,
            then the Conversion Price in effect immediately prior to each such
            issuance shall forthwith be lowered (but never increased) to a
            price equal to the sum of (x) the Conversion Premium plus (y) the
            quotient obtained by dividing:

                      (1) an amount equal to the sum of (x) the total number
                  of shares of Common Stock outstanding immediately prior
                  to such issuance, multiplied by the Market Price in
                  effect immediately prior to such issuance, and (y) the
                  consideration received by the Corporation upon such
                  issuance; by

                      (2) the total number of shares of Common Stock
                  outstanding (including any shares of Common Stock deemed
                  to have been issued pursuant to subdivision (3) of clause
                  (B) below) immediately after the issuance of such Common
                  Stock.

                 (B) For the purposes of any adjustment of the Conversion
            Price pursuant to clause (A) above, the following provisions
            shall be applicable:

                      (1) In the case of the issuance of Common Stock for cash
                  in a public offering or private placement, the
                  consideration shall be deemed to be the amount of cash
                  paid therefor prior to deducting therefrom any usual and
                  customary discounts, commissions or placement fees paid
                  by the Corporation to any underwriter or placement agent
                  in connection with the issuance and sale thereof.

                      (2) In the case of the issuance of Common Stock for a
                  consideration in whole or in part other than cash, the
                  consideration other than cash shall be deemed to be the
                  Fair Value thereof.

                      (3) In the case of the issuance of options to purchase
                  or rights to subscribe for Common Stock, Securities by
                  their terms convertible into or exchangeable for Common
                  Stock, or options to purchase or rights to subscribe for
                  such convertible or exchangeable Securities:

                  (a)   the aggregate maximum number of shares of Common
                        Stock deliverable upon exercise of such options to
                        purchase or rights to subscribe for Common Stock
                        shall be deemed to have been issued at the time  such
                        options or rights were issued and for a consideration
                        equal to the consideration (determined in the manner
                        provided in subdivisions (1) and (2) above), if any,
                        received by the Corporation upon the issuance of such
                        options or rights plus the minimum purchase price
                        provided in such options or rights for the Common
                        Stock covered  thereby;

                  (b)   the aggregate maximum number of shares of Common
                        Stock deliverable upon conversion of or in exchange
                        for any such convertible or exchangeable Securities
                        or upon the exercise of options to purchase or  rights
                        to subscribe for such convertible or exchangeable
                        Securities and subsequent conversion or exchange
                        thereof shall be deemed to have been issued at the
                        time such Securities, options, or rights were issued
                        and for a consideration equal to the consideration
                        received by the Corporation for any such  Securities
                        and related options or rights (excluding any cash
                        received on account of accrued interest or accrued
                        dividends), plus the additional consideration, if any,
                        to be received  by the Corporation upon the conversion
                        or exchange  of such Securities or the exercise of any
                        related  options or rights (the consideration in each
                        case to be determined in the manner provided in
                        subdivisions (1) and (2) above);

                  (c)   on any change in the number of shares or exercise
                        price of Common Stock deliverable upon exercise of
                        any such options or rights or conversions of or
                        exchange for such Securities, the Conversion Price
                        shall forthwith be readjusted to such Conversion
                        Price as would have been obtained had the adjustment
                        made upon the issuance of such options, rights or
                        Securities not converted prior to such change or
                        options or rights related to such Securities not
                        converted prior to such change been made upon the
                        basis of such change; and

                  (d)   on the expiration of any such options or rights, the
                        termination of any such rights to convert or exchange
                        or the expiration of any options or rights related to
                        such convertible or exchangeable Securities, the
                        Conversion Price shall forthwith be readjusted to such
                        Conversion Price as would have obtained had the
                        adjustment made upon the issuance of such options,
                        rights, Securities or options or rights related to
                        such Securities been made upon the basis of the
                        issuance of only the number of shares of Common Stock
                        actually issued upon the exercise of such options or
                        rights, upon the conversion or exchange of such
                        Securities, or upon the exercise of the options or
                        rights related to such Securities and subsequent
                        conversion or exchange thereof.

             (ii) If, at any time after the Original Issuance Date, the
number of shares of Common Stock outstanding is increased by a stock
dividend payable in shares of Common Stock or by a subdivision or split-up
of shares of Common Stock, then, following the record date for the
determination of holders of Common Stock entitled to receive such stock
dividend, subdivision or split-up (or if no record date is set, the date
such stock dividend, subdivision or stock split is consummated), the
Conversion Price shall be appropriately decreased so that the number of
shares of Common Stock issuable on conversion of each share of Series B
Preferred Stock shall be increased in proportion to such increase in
outstanding shares.

            (iii) If, at any time after the Original Issuance Date, the
number of shares of Common Stock outstanding is decreased by a combination
of the outstanding shares of Common Stock, then, following the record date
for such combination, the Conversion Price shall be appropriately increased
so that the number of shares of Common Stock issuable on conversion of each
share of Series B Preferred Stock shall be decreased in proportion to such
decrease in outstanding shares.

             (iv) In the event of any capital reorganization of the
Corporation, any reclassification of the stock of the Corporation (other
than a change in par value or from no par value to par value or from par
value to no par value or as a result of a stock dividend or subdivision,
split-up or combination of shares), or any consolidation or merger of the
Corporation, each share of Series B Preferred Stock shall after such
reorganization, reclassification, consolidation, or merger be convertible
into the kind and number of shares of stock or other Securities or property
of the Corporation or of the corporation resulting from such consolidation
or surviving such merger to which the holder of the number of shares of
Common Stock deliverable (immediately prior to the time of such
reorganization, reclassification, consolidation or merger) upon conversion
of such share of Series B Preferred Stock would have been entitled upon
such reorganization, reclassification, consolidation or merger. The
provisions of this clause shall similarly apply to successive
reorganizations, reclassifications, consolidations or mergers.

              (v) If any event occurs of the type contemplated by the
provisions of this Section 6 but not expressly provided for by such provisions
(including, without limitation, the granting of stock appreciation rights,
phantom stock rights or other rights with equity features), then the
Corporation's Board of Directors shall make an appropriate reduction in the
Conversion Price so as to protect the rights of the holders of the Series B
Preferred Stock.

             (vi) All calculations under this paragraph shall be made to the
nearest one hundredth (1/100) of a cent.

            (vii) In any case in which the provisions of this Section 6(c)
shall require that an adjustment shall become effective immediately after a
record date of an event, the Corporation may defer until the occurrence of
such event (i) issuing to the holder of any share of Series B Preferred
Stock converted after such record date and before the occurrence of such
event the shares of capital stock issuable upon such conversion by reason
of the adjustment required by such event in addition to the shares of
capital stock issuable upon such conversion before giving effect to such
adjustments, and (ii) paying to such holder any amount in cash in lieu of a
fractional share of capital stock pursuant to paragraph (iii) above;
provided, however, that the Corporation shall deliver to such holder an
appropriate instrument evidencing such holder's right to receive such
additional shares and such cash.

           (viii) Whenever the Conversion Price shall be adjusted as provided
in this paragraph (c), the Corporation shall make available for inspection
during regular business hours, at its principal executive offices or at
such other place as may be designated by the Corporation, a statement,
signed by its chief executive officer, showing in detail the facts
requiring such adjustment and the Conversion Price that shall be in effect
after such adjustment. The Corporation shall also cause a copy of such
statement to be sent by first class certified mail, return receipt
requested and postage prepaid, to each holder of Series B Preferred Stock
at such holder's address appearing on the Corporation's records. Where
appropriate, such copy may be given in advance and may be included as part
of any notice required to be mailed under the provisions of paragraph (x)
below.

             (ix) If the Corporation shall propose to take any action of the
types described in clauses (ii), (iii) or (iv) of this paragraph (c) above, the
Corporation shall give notice to each holder of shares of Series B Preferred
Stock, in the manner set forth in paragraph (viii) above, which notice shall
specify the record date, if any, with respect to any such action and the date
on which such action is to take place. Such notice shall also set forth such
facts with respect thereto as shall be reasonably necessary to indicate the
effect of such action (to the extent such effect may be known at the date of
such notice) on the Conversion Price and the number, kind or class of shares
or other Securities or property which shall be deliverable or purchasable upon
the occurrence of such action or deliverable upon conversion of shares of
Series B Preferred Stock. In the case of any action which would require the
fixing of a record date, such notice shall be given at least 10 days prior to
the date so fixed, and in case of all other action, such notice shall be given
at least 10 days prior to the taking of such proposed action. Failure to give
such notice, or any defect therein, shall not affect the legality or validity
of any such action.

              (x) In the event that the Requisite Preferred Holders consent in
writing to limit, or waive in its entirety, any anti-dilution adjustment to
which the holders of the Series B Preferred Stock would otherwise be entitled
hereunder, the Corporation shall not be required to make any adjustment
whatsoever with respect to any Series B Preferred Stock in excess of such
limit or at all, as the terms of such consent may dictate.

             (xi) The Corporation will not, by amendment of its Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the
terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions of
this Section 6 and in the taking of all such action as may be necessary or
appropriate in order to protect the exercise rights of the holders of
Preferred Stock against impairment.

            (xii) The computations of all amounts under this Section 6 shall
be made assuming all other anti-dilution or similar adjustments to be made to
the terms of all other securities resulting from the transaction causing an
adjustment pursuant to this Section 6 have previously been made so as to
maintain the relative economic interest of the Preferred Stock vis a vis all
other securities issued by the Corporation.

           (xiii) The Corporation shall take or cause to be taken such steps
as shall be necessary to ensure that the par value per share of Common Stock
is at all time less than or equal to the Conversion Price.

            (xiv) In the event the Corporation grants, issues or sells any
options, convertible securities or rights to purchase stock, warrants,
securities or other property pro rata to the record holders of any class of
Common Stock (the "Purchase Rights"), then the Preferred Holder shall be
entitled to acquire, upon the terms applicable to such Purchase Rights, the
aggregate number or amount of such stock, warrants, securities or other
property which such Holder could have acquired if such Holder had held the
Common Stock acquirable upon complete conversion of this Series B Preferred
Stock immediately before the date on which a record is taken for the grant,
issuance or sale of such Purchase Rights, or, if no such record is taken,
the date as of the grant, issue or sale of such Purchase Rights.

             (xv) In the event the Corporation shall, at any time or from time
to time after the date hereof, distribute pro rata to the record holders of
Common Stock cash, evidences of its indebtedness, other Securities or other
properties or assets, or any options, warrants or other rights to subscribe
for or purchase any of the foregoing, then (unless the holder of the share of
Series B Preferred Stock shares in such distribution on a ratable basis based
upon the shares of Common Stock issuable upon conversion of such share) the
Conversion Price shall be decreased to a price determined by multiplying the
Conversion Price then in effect by a fraction, the numerator of which shall be
the Market Price less the sum of (X) the cash portion, if any, of such
distribution per share of Common Stock deemed outstanding (exclusive of any
treasury shares) on the record date for such distribution plus (Y) the Fair
Value of such distribution consisting of evidences of indebtedness, other
Securities, properties, assets, options, warrants or subscription or purchase
rights, per share of Common Stock deemed outstanding (exclusive of any
treasury shares) on the record date for such distribution of that portion, if
any, and the denominator of which shall be such Market Price of Common Stock.
The adjustments required by this paragraph (xv) shall be made whenever any such
distribution occurs retroactive to the record date for the determination of
stockholders entitled to receive such distribution.

          (d) Conversion Procedures.

              (i) Each conversion of shares of any class of capital stock of
the Corporation into shares of another class of capital stock of the
Corporation shall be effected by the surrender of the certificate or
certificates representing the shares to be converted (the "Converting Shares")
at the principal office of the Corporation (or such other office or agency of
the Corporation as the Corporation may designate by written notice to the
holders of such class of capital stock) at any time during its usual business
hours, together with written notice by the holder of such Converting Shares,
stating that such holder desires to convert the Converting Shares, or a stated
number of the shares represented by such certificate or certificates, into an
equal number of shares of the class into which such shares may be converted
(the "Converted Shares"). Such notice shall also state the name or names (with
addresses) and denominations in which the certificate or certificates for
Converted Shares are to be issued and shall include instructions for the
delivery thereof. A holder of Converting Shares may make any such notice
of conversion, whether such conversion is in connection with a Sale of the
Corporation or otherwise, conditional upon the happening of any event or
the passage of such time as is specified by such holder in such conversion
notice, and may rescind any notice of conversion prior to the effective
time thereof specified in any such notice. Promptly after such surrender
and the receipt of such written notice of conversion, the Corporation will
issue and deliver in accordance with the surrendering holder's instructions
the certificate or certificates evidencing the Converted Shares issuable
upon such conversion, and the Corporation will deliver to the converting
holder a certificate (which shall contain such legends as were set forth on
the surrendered certificate or certificates) representing any shares which
were represented by the certificate or certificates that were delivered to
the Corporation in connection with such conversion, but which were not
converted. Such conversion, to the extent permitted by law, shall be
deemed to have been effected as of the close of business on the date on
which such certificate or certificates shall have been surrendered and such
notice shall have been received by the Corporation, and at such time the
rights of the holder of the Converting Shares as such holder shall cease
and the person or persons in whose name or names the certificate or
certificates for the Converted Shares are to be issued upon such conversion
shall be deemed to have become the holder or holders of record of the
Converted Shares.

             (ii) Upon issuance of shares in accordance with this Section, such
Converted Shares shall be deemed to be duly authorized, validly issued, fully
paid and non-assessable, with no personal liability attaching to the ownership
thereof and free from all taxes, liens or charges with respect thereto due to
any action of the Corporation. The Corporation shall take all such actions as
may be necessary to assure that all such shares may be so issued without
violation of any Applicable Law or governmental regulation or any requirements
of any domestic securities exchange upon which such shares may be listed
(except for official notice of issuance which will be immediately transmitted
by the Corporation upon issuance). The Corporation shall not close its books
against the transfer of shares in any manner which would interfere with the
timely conversion of any shares. The issuance of certificates for shares of
any class of capital stock (upon conversion of shares of any other class of
capital stock or otherwise) shall be made without charge to the holders of
such shares for any issuance tax in respect thereof or other cost incurred by
the Corporation in connection with such conversion and/or the issuance of such
shares; provided, however, that the Corporation shall not be required to pay
any tax which may be payable in respect of any transfer involved in the
issuance and delivery of any certificate in a name other than that of the
holder of the shares converted. In the event the holder of the shares
converted hereunder, in connection with the conversion of shares hereunder,
shall be required to file a notification pursuant to the Hart-Scott-Rodino
Anti-Trust Improvements Act of 1976 (the "HSR Act"), the Corporation and the
holder shall take all actions necessary to comply with such notification
requirement and the conversion hereunder of the shares, or the accumulated and

the applicable waiting period. The Corporation will pay and save the holders
of Series B Preferred Shares harmless against all liability for the payment of
all actual and reasonable costs and expenses incurred by such holder in
connection with any requirements to file a notification pursuant to the HSR
Act. No fractional shares of Common Stock or scrip shall be issued upon
conversion of any shares. The number of full shares issuable upon conversion
shall be computed on the basis of the aggregate number of shares to be
converted by a holder. Instead of any fractional shares which would otherwise
be issuable upon conversion of the shares, the Corporation shall pay a cash
adjustment in respect of such fractional interest in an amount equal to the
product of (i) the Fair Value of one share of such Common Stock and (ii) such
fractional interest. The holders of fractional interests shall not be entitled
to any rights as stockholders of the Corporation in respect of such fractional
interests.

       7. Reservation of Shares.

          The Corporation shall at all times reserve and keep available out of
its authorized but unissued shares of Common Stock, solely for the purpose of
issuance upon the conversion of shares of Series B Preferred Stock hereunder,
such number of shares of such class as are then issuable upon the conversion
of all outstanding shares of such other class which may be converted.

       8. Shares Acquired by the Corporation.

          Any shares of Series B Preferred Stock which are redeemed, converted
or otherwise acquired by the Corporation shall be canceled and shall not be
reissued (as treasury shares), sold or transferred as Series B Preferred Stock
but such shares shall become unclassified Preferred Stock of the Corporation.

all meetings of the Board. Such right shall from time to time be exercisable
by delivery to the Corporation of written notice from the Requisite Preferred
Holders specifying the names of such Observers. The number of Observers shall
at all times and from time to time be equal to that number of members of the
Board that the Preferred Holders are then entitled to designate but whose
seats on the Board are at the time vacant.

             (ii) The Corporation will give each Observer reasonable prior
notice (it being agreed that the same prior notice given to the Board shall
be deemed reasonable prior notice) in any manner permitted in the
Corporation's By-laws for notices to directors of the time and place of any
proposed meeting of the Board, such notice in all cases to include true and
complete copies of all documents furnished to any director in connection
with such meeting. Each such Observer will be entitled to be present in
person as an observer at any such meeting or, if a meeting is held by
telephone conference, to participate therein for the purpose of listening

papers which may be distributed from time to time to the directors of the

entitled to receive, out of the assets of the Corporation legally available

shall rank senior to the Common Stock, pari passu with the Series A Preferred
Stock but junior to all other series of Preferred Stock), an amount per share
equal to (the "Preferred Liquidation Preference") the Original Cost of such
share. If, upon any Liquidation, the assets of the Corporation available for
distribution to its stockholders shall be insufficient to pay the Preferred
Holders the full amount to which it shall be entitled, then the Corporation
shall pay the Preferred Holders the aggregate unpaid Preferred Liquidation
Preference as soon as practicable after the Corporation has funds legally
available therefor. In the event of any Liquidation, after payment shall have
been made to the Preferred Holders in the full amount to which it is entitled,
the holders of shares of Common Stock shall be entitled, to the exclusion of
the Preferred Holders, to share, according to their respective rights and
preferences, in all remaining assets of the Corporation available for
distribution to its stockholders.

       5. Redemption.

          (a) Subject to the Corporation having funds legally available for
such purpose, the Corporation shall redeem all of the shares of the Series C
Preferred Stock then outstanding, on the first to occur of (A) on the Maturity
Date, so long as all of the outstanding Notes, the outstanding shares of the
Series B Preferred Stock and the outstanding shares of the Series D Preferred
Stock shall have been redeemed or converted prior thereto, (B) upon the
occurrence of the Mandatory Conversion Event, or (C) in the event a Series C
Redemption Event shall have occurred (each of clauses (A), (B) and (C) above,
a "Redemption Event"). The per share redemption price at which shares of
Series C Preferred Stock are to be redeemed pursuant to this Section 5(a)
shall be equal to the Liquidation Preference Amount (the "Redemption Price").

          (b) On and after any redemption date (the "Redemption Date") pursuant
to this Section 5 (unless default shall be made by the Corporation in the
payment of the Redemption Price, in which event such rights shall be
exercisable until such default is cured), all rights in respect of the shares
of the Series C Preferred Stock to be redeemed, except the right to receive
the Redemption Price, shall cease and terminate, and such shares shall no
longer be deemed to be outstanding, whether or not the certificates
representing such shares have been received by the Corporation.

          (c) Any communication or notice relating to redemption given pursuant
to this Section 5 shall be sent by first-class certified mail, return receipt
requested, postage prepaid, to the Preferred Holders, at their respective
addresses as the same shall appear on the books of the Corporation, or to the
Corporation at the address of its principal, or registered office, as the case
may be.

          (d) At any time on or after the Redemption Date, the Preferred
Holders shall be entitled to receive the Redemption Price upon actual
delivery to the Corporation or its agents of the certificates representing
the shares of the Series C Preferred Stock to be redeemed.

          (e) Any redemption payments by the Corporation pursuant to this
Section 5 shall be paid in cash.

          (f) Any shares of Series C Preferred Stock which are redeemed,
converted or otherwise acquired by the Corporation shall be canceled and shall
not be reissued (as treasury shares), sold or transferred as Series C
Preferred but such shares shall become unclassified Preferred Stock of the
Corporation.

dividends. Any dividends which accrue pursuant to this Section 4(a)(i) and
which are not paid prior to the next succeeding Preferred Dividend Payment
Date shall be classified as "accumulated dividends" and shall remain

Stock on each Preferred Dividend Payment Date shall be paid to the holders

date upon which the resolution fixing such Preferred Record Date is

Preferred Record Date shall be deemed to be the same date as the applicable
Preferred Dividend Payment Date.

             (iv) Except as otherwise provided herein, if at any time the
Corporation pays less than the total amount of dividends then accrued with
respect to the Series D Preferred Stock, such payment shall be distributed

number of shares of Series D Preferred Stock then held by each holder.

       (b) Liquidation.

          In the event of any Liquidation, the holders of shares of Series D
Preferred Stock then outstanding shall be entitled to receive, out of the
assets of the Corporation legally available for distribution to its
stockholders, before any payment shall be made to the holders of any stock
ranking on Liquidation junior to the Series D Preferred Stock (with respect to
rights on Liquidation, the Series D Preferred Stock shall rank senior to the
Common Stock and any other class of Junior Stock, but pari passu with the
Series B Preferred Stock), an amount per share equal to (the "Preferred
Liquidation Preference") the greater of (X) the Original Cost of such share
plus an amount equal to any accrued but unpaid dividends on each share to the
date of payment or (Y) the amount that would otherwise be distributed to such
holder in such Liquidation if nothing was paid pursuant to clause (X) and such
holder converted such shares into shares of Common Stock in accordance with
the provisions of this Article XII. If, upon any Liquidation, the assets of
the Corporation available for distribution to its stockholders shall be
insufficient to pay the holders of shares of the Series D Preferred Stock the
full amounts to which they respectively shall be entitled, the holders of
shares of Series D Preferred Stock shall share ratably in any distribution of
assets according to the respective amounts which would be payable with respect
to the shares held by them upon such distribution if all amounts payable on or
with respect to said shares were paid in full. In the event of any
Liquidation, after payment shall have been made to the holders of shares of
Series D Preferred Stock in the full amount to which they are entitled, the
holders of shares of capital stock ranking junior to the Series D Preferred
Stock on Liquidation shall be entitled, to the exclusion of the holders of the
Series D Preferred Stock, to share, according to their respective rights and
preferences, in all remaining assets of the Corporation available for
distribution to its stockholders.

       5. Redemption.

          (a) Redemption at the Option of the Holders.

              (i) At any time on or after the occurrence or continuation of
an Event of Default the Requisite Preferred Holders may elect to have the
Corporation redeem all (but not less than all) of the outstanding shares of
Series D Preferred Stock at a price per share equal to (i) in the case of a
redemption option caused by a Change of Control (the "Change of Control
Price"), equal to 101% of the Original Cost thereof plus without
duplication, an amount in cash accrued and unpaid dividends thereon, and
(ii) in the case of a redemption option caused by an Event of Default,
other than a Change of Control, the greater of the Original Cost of such
share plus an amount equal to all accrued and unpaid dividends on each
share, if any, to the date of payment (in either case, the "Redemption
Price"), by giving written notice to the Corporation of such election (the
"Investor Notice of Election"), whereupon the Corporation shall be
obligated to repurchase such shares of Series D Preferred Stock on such
date (the "Investor Optional Redemption Date") as shall be determined by
the Corporation, but in any event not earlier than 10 days and not later
than 30 days after the date on which the Investor Notice of Election is
delivered to the Corporation. Promptly (but in no event later than five
days) after the delivery of the Investor Notice of Election to the
Corporation, the Corporation shall send written notice (the "Optional
Redemption Notice") to each of the holders of the Series D Preferred Stock.
The Optional Redemption Notice shall specify the Investor Optional
Redemption Date and the location of the Corporation's principal executive
office or place of business where the closing will occur.

            (ii) Closing.

                (A) The closing of the Corporation's redemption of the Series
          D Preferred Stock pursuant to this Section 5(c) above shall take
          place at 11:00 a.m. New York City time on the Investor Optional
          Redemption Date at the Corporation's principal executive office
          or place of business. At the closing, the Corporation shall pay
          to each of the holders of the Series D Preferred Stock, against
          the Corporation's receipt from such holder of the certificate or
          certificates representing the shares of such series of Series D
          Preferred Stock then held by such holder, an amount equal to the
          Redemption Price. All such payments shall be made by wire
          transfer of immediately available funds, or if such holder shall
          not have specified wire transfer instructions to the Corporation
          prior to the closing, by certified or official bank check made
          payable to the order of such  holder.

                (B)  If the funds of the Corporation (without rendering the
          Corporation insolvent) available for redemption of shares of
          Series D Preferred Stock on any Investor Redemption Date are
          insufficient to redeem the total number of such shares to be
          redeemed on such date, those funds which are legally available
          (without rendering the Corporation insolvent) shall be used to
          redeem the maximum possible number of shares ratably among the
          holders of such shares based upon the aggregate number of
          such shares held by each such holder. At any time thereafter
          when additional funds of the Corporation are legally available
          which will not make the Corporation insolvent for the
          redemption of shares such funds shall immediately be used to
          redeem the balance of the shares which the Corporation has
          become obligated to redeem on any Investor Redemption Date but
          which it had not redeemed.

          (b) Redemption at the Option of the Corporation.

          The Series D Preferred Stock is redeemable at the option of the
Corporation, in whole or in part at a per share price equal to the Original
Cost of such share plus any accrued but unpaid dividends on each share, if
any, to the date of payment; provided however, that in the event the
Corporation shall redeem all or any portion of the shares of the outstanding
Series D Preferred Shares, then the holder of Series D Preferred Shares shall
be entitled to receive a warrant (the "Warrant") that is initially exercisable
for that number of shares of Common Stock equal to the number of shares of
Common Stock, including the accrued but unpaid dividends thereon, into which
such redeemed shares would have been convertible in the event of an optional
conversion at such time pursuant to Section 6(a) hereof, of the shares
redeemed hereunder immediately prior to such redemption; provided, further,
however, that in the event the Series D Preferred Shares shall be redeemed by
the Corporation in connection with a Change of Control the amount paid by the
Corporation to the holder in connection with such prepayment shall equal the
Change of Control Price. The initial exercise price for each share of Common
Stock issuable upon exercise of the Warrant shall be equal to the Conversion
Price in effect immediately prior to the prepayment. The Warrant shall have
customary cashless conversion and exercise provisions, customary anti-dilution
protections economically identical to the Series D Preferred Stock and shall
otherwise be in form and substance reasonably acceptable to the holder of such
shares.

          (c) General

              (i)  No shares of Series D Preferred Stock are entitled to any
dividends accumulating after the date on which the full redemption price for
such share is paid to the holder thereof. On such date all rights of the
holder of such share shall cease, and such share shall not be deemed to be
outstanding.

             (ii) Any shares of Series D Preferred Stock which are redeemed or
otherwise acquired by the Corporation shall be canceled and shall not be
reissued (as treasury shares), sold or transferred.

            (iii) Neither the Corporation nor any Subsidiaries shall offer to
purchase, redeem or acquire any shares of Series D Preferred Stock other than
pursuant to the terms of this Article XII or pursuant to a purchase offer
made to all holders of Series D Preferred Stock pro rata based upon the
number of such shares owned by such holders.

       6. Conversion.

          (a) Optional Conversion of Series D Preferred Stock into Common
Stock.

          Subject to and in compliance with the applicable provisions of this
Article XII, each holder of shares of Series D Preferred Stock shall have the
right, at such holder's option, at any time and from time to time, to convert
any such share, or the accrued but unpaid dividends accrued thereon, into that
number of fully paid and nonassessable shares of Common Stock (provided that
in such event the holder shall have the option to require that such shares be
Qualified Securities) equal to the quotient obtained by dividing (x) the sum
of the Original Cost of such shares of Series D Preferred Stock, plus all
accrued but unpaid dividends thereon, by (y) the Conversion Price, as last
adjusted and then in effect, by surrender of the certificates representing
such share to be converted; provided however, that the Preferred Holder shall
have the right to convert all or a portion of the accrued but unpaid dividends
on any share of Series D Preferred Stock without the need to convert the share
of Series D Preferred Stock on which such dividends accrued. The Corporation
shall give the Preferred Holders reasonable prior notice of a Sale of the
Corporation, including the price and material terms and conditions thereof, in
order to provide the Preferred Holders reasonable opportunity to consider
whether to redeem or convert the Series D Preferred Stock, or the accrued but
unpaid dividends accrued thereon, into Common Stock at or prior to such Sale
of the Corporation. If the price or material terms or conditions of such
transaction thereafter change, the Corporation shall promptly deliver written
notice to the Preferred Holders specifying such changes. Upon conversion, the
Corporation will issue fractional shares of its Common Stock, as applicable,
and shall not distribute cash in lieu of such fractional shares unless such
cash distribution is approved by the Requisite Preferred Holders.

          (b)  Mandatory Conversion of Series D Preferred Stock into Common
Stock.

          Upon the occurrence of a Mandatory Conversion Event, all shares of
Series D Preferred Stock then outstanding shall, at the option of the
Corporation by virtue of the delivery of a notice by the Corporation to the
holder notifying the holder of the occurrence of such Mandatory Conversion
Event, which notice shall state the date upon which such conversion shall
become effective (the "Effective Date") (which date shall be no earlier
than 15 Business Days after the date of delivery), and without any action on
the part of the holders thereof, shall on the Effective Date be deemed
automatically converted, in accordance with Section 6(d)(ii), into that number
of fully paid and nonassessable shares of Qualified Securities into which such
shares, including the accrued but unpaid dividends accrued thereon, would have
been convertible in the event of optional conversion at such time pursuant to
subsection (a) above. Upon conversion, the Corporation will issue fractional
shares of its Qualified Securities, as applicable, and shall not distribute
cash in lieu of such fractional shares unless such cash distribution is
approved by the Requisite Preferred Holders.

          (c) Adjustment of Conversion Price.

              (i) The initial Conversion Price was established based upon the
Corporation's representation and warranty in the Securities Purchase Agreement
that 1,628,664 shares of Common Stock represented (the "Target Percentage") no
less than 10.68% of the 15,240,908 Common Stock Equivalents outstanding as of
the date of the Securities Purchase Agreement (inclusive of the 1,042,150
Common Stock Equivalents reserved but not necessarily issued under the Equity
Incentive Plans and the 4,885,993 shares issuable upon conversion of the
Securities to be issued pursuant to the Purchase Agreement). In the event such
representation and warranty is untrue, the Conversion Price shall be reduced
(but not increased) to such Conversion Price as would have been obtained had
the initial Conversion Price been properly set to meet the Target Percentage.

             (ii) The Conversion Price shall also be subject to adjustment
from time to time as follows:

                (A) If the Corporation shall, at any time or from time to time
          after the First Closing Date, issue any shares of Common Stock
          (other than Excluded Stock) without consideration or for a
          consideration per share less than the Adjusted Market Price in
          effect immediately prior to the issuance of such Common Stock,
          then the Conversion Price in effect immediately prior to each
          such issuance shall forthwith be lowered (but never increased) to
          a price equal to the sum of (x) the Conversion Premium and (y)
          the quotient obtained by dividing:

                    (1) an amount equal to the sum of (x) the total number of
                shares of Common Stock outstanding immediately prior to
                such issuance, multiplied by the Market Price in effect
                immediately prior to such issuance, and (y) the
                consideration received by the Corporation upon such
                issuance; by

                    (2) the total number of shares of Common Stock
                outstanding (including any shares of Common Stock deemed to
                have been issued pursuant to subdivision (3) of clause (B)
                below) immediately after the issuance of such Common Stock.

                    (B) For the purposes of any adjustment of the Conversion
          Price pursuant to clause (A) above, the following provisions
          shall be applicable:

                    (1) In the case of the issuance of Common Stock for cash
                in a public offering or private placement, the consideration
                shall be deemed to be the amount of cash paid therefor prior
                to deducting therefrom any usual and customary discounts,
                commissions or placement fees paid by the Corporation to any
                underwriter or placement agent in connection with the
                issuance and sale thereof.

                    (2) In the case of the issuance of Common Stock for a
                consideration in whole or in part other than cash, the
                consideration other than cash shall be deemed to be the
                Fair Value thereof.

                    (3) In the case of the issuance of options to purchase or
                rights to subscribe for Common Stock, Securities by their
                terms convertible into or exchangeable for Common Stock, or
                options to purchase or rights to subscribe for such
                convertible or exchangeable Securities:

                        (a) the aggregate maximum number of shares of
                            Common Stock deliverable upon exercise of such
                            options to purchase or rights to subscribe for
                            Common Stock shall be deemed to have been
                            issued at the time such options or rights were
                            issued and for a consideration equal to the
                            consideration (determined in the manner provided
                            in subdivisions (1) and (2) above), if any,
                            received by the Corporation upon the issuance
                            of such options or rights plus the minimum
                            purchase price provided in such options or
                            rights for the Common Stock covered thereby;

                        (b) the aggregate maximum number of shares of
                            Common Stock deliverable upon conversion of or
                            in exchange for any such convertible or
                            exchangeable Securities or upon the exercise of
                            options to purchase or rights to subscribe for
                            such convertible or exchangeable Securities
                            and subsequent conversion or exchange thereof
                            shall be deemed to have been issued at the time
                            such Securities, options, or rights were issued
                            and for a consideration equal to the
                            consideration  received by the Corporation for
                            any such Securities and related options or
                            rights (excluding any cash received on account
                            of accrued interest or accrued dividends), plus
                            the additional consideration, if any, to be
                            received by the Corporation upon the conversion
                            or exchange of such Securities or the exercise
                            of any related options or rights (the
                            consideration in each case to be determined in
                            the manner provided in subdivisions (1) and (2)
                            above);

                        (c) on any change in the number of shares or
                            exercise price of Common Stock deliverable upon
                            exercise of any such options or rights or
                            conversions of or exchange for such Securities,
                            the Conversion Price shall forthwith be
                            readjusted to such Conversion Price as would
                            have been obtained had the adjustment made upon
                            the issuance of such options, rights or
                            Securities not converted prior to such change
                            or options or rights related to such Securities
                            not converted prior to such change been made
                            upon the basis of such change; and

                        (d) on the expiration of any such options or rights,
                            the termination of any such rights to convert or
                            exchange or the expiration of any options or
                            rights related to such convertible or
                            exchangeable Securities, the Conversion Price
                            shall forthwith be readjusted to such Conversion
                            Price as would have obtained had the adjustment
                            made upon the issuance of such options, rights,
                            Securities or options or rights related to such
                            Securities been made upon the basis of the
                            issuance of only the number of shares of Common
                            Stock actually issued upon the exercise of such
                            options or rights, upon the conversion or
                            exchange of such Securities, or upon the
                            exercise of the options or rights related to
                            such Securities and subsequent conversion or
                            exchange thereof.

             (iii) If, at any time after the Original Issuance Date, the
number of shares of Common Stock outstanding is increased by a stock
dividend payable in shares of Common Stock or by a subdivision or split-up
of shares of Common Stock, then, following the record date for the
determination of holders of Common Stock entitled to receive such stock
dividend, subdivision or split-up (or if no record date is set, the date
such stock dividend, subdivision or stock split is consummated), the
Conversion Price shall be appropriately decreased so that the number of
shares of Common Stock issuable on conversion of each share of Series D
Preferred Stock shall be increased in proportion to such increase in
outstanding shares.

             (iv) If, at any time after the Original Issuance Date, the number
of shares of Common Stock outstanding is decreased by a combination of the
outstanding shares of Common Stock, then, following the record date for such
combination, the Conversion Price shall be appropriately increased so that the
number of shares of Common Stock issuable on conversion of each share of
Series D Preferred Stock shall be decreased in proportion to such decrease in
outstanding shares.

              (v) In the event of any capital reorganization of the
Corporation, any reclassification of the stock of the Corporation (other
than a change in par value or from no par value to par value or from par
value to no par value or as a result of a stock dividend or subdivision,
split-up or combination of shares), or any consolidation or merger of the
Corporation, each share of Series D Preferred Stock shall after such
reorganization, reclassification, consolidation, or merger be convertible
into the kind and number of shares of stock or other Securities or property
of the Corporation or of the corporation resulting from such consolidation
or surviving such merger to which the holder of the number of shares of
Common Stock deliverable (immediately prior to the time of such
reorganization, reclassification, consolidation or merger) upon conversion
of such share of Series D Preferred Stock would have been entitled upon
such reorganization, reclassification, consolidation or merger. The
provisions of this clause shall similarly apply to successive
reorganizations, reclassifications, consolidations or mergers.

             (vi) If any event occurs of the type contemplated by the
provisions of this Section 6 but not expressly provided for by such
provisions (including, without limitation, the granting of stock
appreciation rights, phantom stock rights or other rights with equity
features), then the Corporation's Board of Directors shall make an
appropriate reduction in the Conversion Price so as to protect the rights
of the holders of the Series D Preferred Stock.

            (vii) All calculations under this paragraph shall be made to the
nearest one hundredth (1/100) of a cent.

           (viii) In any case in which the provisions of this Section 6(c)
shall require that an adjustment shall become effective immediately after a
record date of an event, the Corporation may defer until the occurrence of
such event (i) issuing to the holder of any share of Series D Preferred Stock
converted after such record date and before the occurrence of such event the
shares of capital stock issuable upon such conversion by reason of the
adjustment required by such event in addition to the shares of capital
stock issuable upon such conversion before giving effect to such
adjustments, and (ii) paying to such holder any amount in cash in lieu of a
fractional share of capital stock pursuant to paragraph (iii) above;
provided, however, that the Corporation shall deliver to such holder an
appropriate instrument evidencing such holder's right to receive such
additional shares and such cash.

             (ix) Whenever the Conversion Price shall be adjusted as provided
in this paragraph (c), the Corporation shall make available for inspection
during regular business hours, at its principal executive offices or at such
other place as may be designated by the Corporation, a statement, signed by its
chief executive officer, showing in detail the facts requiring such adjustment
and the Conversion Price that shall be in effect after such adjustment. The
Corporation shall also cause a copy of such statement to be sent by first
class certified mail, return receipt requested and postage prepaid, to each
holder of Series D Preferred Stock at such holder's address appearing on the
Corporation's records. Where appropriate, such copy may be given in advance
and may be included as part of any notice required to be mailed under the
provisions of paragraph (x) below.

              (x) If the Corporation shall propose to take any action of the
types described in clauses (iii), (iv) or (v) of this paragraph (c) above, the
Corporation shall give notice to each holder of shares of Series D Preferred
Stock, in the manner set forth in paragraph (ix) above, which notice shall
specify the record date, if any, with respect to any such action and the date
on which such action is to take place. Such notice shall also set forth such
facts with respect thereto as shall be reasonably necessary to indicate the
effect of such action (to the extent such effect may be known at the date of
such notice) on the Conversion Price and the number, kind or class of shares
or other Securities or property which shall be deliverable or purchasable upon
the occurrence of such action or deliverable upon conversion of shares of
Series D Preferred Stock. In the case of any action which would require the
fixing of a record date, such notice shall be given at least 10 days prior to
the date so fixed, and in case of all other action, such notice shall be given
at least 10 days prior to the taking of such proposed action. Failure to give
such notice, or any defect therein, shall not affect the legality or validity
of any such action.

             (xi) In the event that the Requisite Preferred Holders consent in
writing to limit, or waive in its entirety, any anti-dilution adjustment to
which the holders of the Series D Preferred Stock would otherwise be entitled
hereunder, the Corporation shall not be required to make any adjustment
whatsoever with respect to any Series D Preferred Stock in excess of such
limit or at all, as the terms of such consent may dictate.

            (xii) The Corporation will not, by amendment of its Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the
terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions of
this Section 6 and in the taking of all such action as may be necessary or
appropriate in order to protect the exercise rights of the holders of
Preferred Stock against impairment.

           (xiii) The computations of all amounts under this Section 6 shall
be made assuming all other anti-dilution or similar adjustments to be made to
the terms of all other securities resulting from the transaction causing an
adjustment pursuant to this Section 6 have previously been made so as to
maintain the relative economic interest of the Preferred Stock vis a vis all
other securities issued by the Corporation.

            (xiv) The Corporation shall take or cause to be taken such steps
as shall be necessary to ensure that the par value per share of Common Stock
is at all time less than or equal to the Conversion Price.

             (xv) In the event the Corporation grants, issues or sells any
options, convertible securities or rights to purchase stock, warrants,
securities or other property pro rata to the record holders of any class of
Common Stock (the "Purchase Rights"), then the Preferred Holder shall be
entitled to acquire, upon the terms applicable to such Purchase Rights, the
aggregate number or amount of such stock, warrants, securities or other
property which such Holder could have acquired if such Holder had held the
Common Stock acquirable upon complete conversion of this Series D Preferred
Stock immediately before the date on which a record is taken for the grant,
issuance or sale of such Purchase Rights, or, if no such record is taken,
the date as of the grant, issue or sale of such Purchase Rights.

          (d) Conversion Procedures.

              (i) Each conversion of shares of any class of capital stock of
          the Corporation into shares of another class of capital stock of the
          Corporation shall be effected by the surrender of the certificate or
          certificates representing the shares to be converted (the
          "Converting Shares") at the principal office of the Corporation
          (or such other office or agency of the Corporation as the
          Corporation may designate by written notice to the holders of
          such class of capital stock) at any time during its usual
          business hours, together with written notice by the holder of
          such Converting Shares, stating that such holder desires to
          convert the Converting Shares, or a stated number of the shares
          represented by such certificate or certificates, into an equal
          number of shares of the class into which such shares may be
          converted (the "Converted Shares"). Such notice shall also state
          the name or names (with addresses) and denominations in which the
          certificate or certificates for Converted Shares are to be issued
          and shall include instructions for the delivery thereof. A
          holder of Converting Shares may make any such notice of
          conversion, whether such conversion is in connection with a Sale
          of the Corporation or otherwise, conditional upon the happening
          of any event or the passage of such time as is specified by such
          holder in such conversion notice, and may rescind any notice of
          conversion prior to the effective time thereof specified in any
          such notice. Promptly after such surrender and the receipt of
          such written notice of conversion, the Corporation will issue and
          deliver in accordance with the surrendering holder's instructions
          the certificate or certificates evidencing the Converted Shares
          issuable upon such conversion, and the Corporation will deliver
          to the converting holder a certificate (which shall contain such
          legends as were set forth on the surrendered certificate or
          certificates) representing any shares which were represented by
          the certificate or certificates that were delivered to the
          Corporation in connection with such conversion, but which were
          not converted. Such conversion, to the extent permitted by law,
          shall be deemed to have been effected as of the close of business
          on the date on which such certificate or certificates shall have
          been surrendered and such notice shall have been received by the
          Corporation, and at such time the rights of the holder of the
          Converting Shares as such holder shall cease and the person or
          persons in whose name or names the certificate or certificates
          for the Converted Shares are to be issued upon such conversion
          shall be deemed to have become the holder or holders of record of
          the Converted Shares.

             (ii)  Upon issuance of shares in accordance with this Section,
          such Converted Shares shall be deemed to be duly authorized,
          validly issued, fully paid and non-assessable, with no personal
          liability attaching to the ownership thereof and free from all
          taxes, liens or charges with respect thereto due to any action of
          the Corporation. The Corporation shall take all such actions as
          may be necessary to assure that all such shares may be so issued
          without violation of any Applicable Law or governmental
          regulation or any requirements of any domestic securities
          exchange upon which such shares may be listed (except for
          official notice of issuance which will be immediately transmitted
          by the Corporation upon issuance). The Corporation shall not
          close its books against the transfer of shares in any manner
          which would interfere with the timely conversion of any shares.
          The issuance of certificates for shares of any class of capital
          stock (upon conversion of shares of any other class of capital
          stock or otherwise) shall be made without charge to the holders
          of such shares for any issuance tax in respect thereof or other
          cost incurred by the Corporation in connection with such
          conversion and/or the issuance of such shares; provided, however,
          that the Corporation shall not be required to pay any tax which
          may be payable in respect of any transfer involved in the
          issuance and delivery of any certificate in a name other than
          that of the holder of the shares converted. In the event the
          holder of the shares converted hereunder, in connection with the
          conversion of shares hereunder, shall be required to file a
          notification pursuant to the Hart-Scott-Rodino Anti-Trust
          Improvements Act of 1976 (the "HSR Act"), the Corporation and the
          holder shall take all actions necessary to comply with such
          notification requirement and the conversion hereunder of the
          shares, or the accrued but unpaid dividends on such shares, shall
          become effective upon the expiration of the applicable waiting
          period. Subject to Sections 6(a) and (b), no fractional shares
          of Common Stock or scrip shall be issued upon conversion of any
          shares. The Corporation will pay and save the holder of Series D
          Preferred Shares harmless against all liability for the payment
          of all actual and reasonable costs and expenses incurred by the
          holder in connection with any requirements to file a notification
          pursuant to the HSR Act. The number of full shares issuable upon
          conversion shall be computed on the basis of the aggregate number
          of shares to be converted by a holder. Instead of any fractional
          shares which would otherwise be issuable upon conversion of the
          shares, the Corporation shall pay a cash adjustment in respect of
          such fractional interest in an amount equal to the product of (i)
          the Fair Value of one share of such Common Stock and (ii) such
          fractional interest. The holders of fractional interests shall
          not be entitled to any rights as stockholders of the Corporation
          in respect of such fractional interests.

       7. Reservation of Shares.

          The Corporation shall at all times reserve and keep available out of
its authorized but unissued shares of Common Stock, solely for the purpose of
issuance upon the conversion of shares of Series D Preferred Stock hereunder,
such number of shares of such class as are then issuable upon the conversion
of all outstanding shares of such other class which may be converted.

       8. Shares Acquired by the Corporation.

          Any shares of Series D Preferred Stock which are redeemed, converted
or otherwise acquired by the Corporation shall be canceled and shall not be
reissued (as treasury shares), sold or transferred as Series D Preferred Stock
but such shares shall become unclassified Preferred Stock of the Corporation.

         SECTION 2. Required Registration.

promptly give written notice to the other Purchasers of its requirement to so
register such Registrable Shares and, upon the written request, delivered to
the Company within 30 days after delivery of any such notice by the Company, of
the other Purchasers to include in such registration Registrable Shares (which

with the following provisions:

         efforts to file and cause to become effective (A) more than one
         Registration Statement initiated pursuant to Section 2(a) (provided,

         foregoing condition is satisfied, (B) any Registration Statement
         during any period in which any other registration statement (other

         or were sold has been filed and not withdrawn or has been declared
         effective within the prior 90 days, or (C) any Registration Statement
         if the aggregate market value of the Registrable Shares to be
         registered thereunder, whether held by CVCA or others, shall be less
         than $5 million;

                  (ii) the Company may delay the filing or effectiveness of any
         Registration Statement for a period of up to 90 days after the date of
         a request for registration pursuant to Section 2(a) if at the time of
         such request the Company is engaged in a Material Transaction; and

                  (iii) with respect to any registration pursuant to Section
         2(a), the Company may include in such registration any Primary Shares
         or Other Shares; provided, however, that if the managing underwriter
         advises the Company that the inclusion of all Registrable Shares,
         Primary Shares and Other Shares proposed to be included in such
         registration would interfere with the successful marketing (including
         pricing) of all such securities, then the number of Registrable
         Shares, Primary Shares and Other Shares proposed to be included in
         such registration shall be included in the following order:

                           (A) first, the Registrable Shares held by the
                  Purchasers requesting that their Registrable Shares be
                  included in such registration pursuant to Section 2(a), pro
                  rata based upon the number of Restricted Securities owned by
                  each such Purchaser at the time of such registration;

                           (B) second, the Primary Shares; and

                           (C) third, the Other Shares.

                  (c) A requested registration under this Section 2 may be
         rescinded prior to such registration being declared effective by the
         Commission by written notice to the Company from CVCA; provided,
         however, that such rescinded registration shall not count as a
         registration initiated pursuant to this Section 2 for purposes of
         subclause (A) of clause (i) of subsection (b) above if the Company
         shall have been reimbursed (pro rata by the Purchasers requesting
         registration or in such other proportion as they may agree) for all
         out-of-pocket expenses incurred by the Company in connection with such
         rescinded registration.

         SECTION 3. Shelf Registration. If at any time the Company shall be
requested by the Requisite Purchasers to file a shelf registration statement
for an offering to be made on a continuous basis pursuant to Rule 415
promulgated under the Securities Act covering the Registrable Shares, then:

                           (i) the Company shall, as expeditiously as
                  practicable, file a shelf registration statement under the
                  Securities Act permitting registration of such Purchasers'
                  Registrable Shares for resale by Purchasers in the manner or
                  manners designated by them (including, without limitation,
                  one or more underwritten offerings);

                           (ii) the Company shall use its best efforts to keep
                  such shelf registration statement continuously effective
                  under the Securities Act until the date which is 18 months
                  from its effective date, or such shorter period ending when
                  all the Registrable Shares covered by such shelf registration
                  statement have been sold in the manner set forth and as
                  contemplated in the shelf registration statement; and

                           (iii) the Company shall promptly supplement and
                  amend the shelf registration statement if required by the
                  rules, regulations or instructions applicable to the
                  registration form used for such shelf registration statement,
                  if required by the Securities Act, or if reasonably requested
                  by CVCA or by any underwriter of the Registrable Shares
                  registered thereunder.

         SECTION 4. Piggyback Registration. If the Company at any time proposes
for any reason to register Primary Shares or Other Shares under the Securities
Act (other than on Form S-4 or Form S-8 promulgated under the Securities Act or
any successor forms thereto), it shall promptly give written notice to each
Purchaser of its intention so to register the Primary Shares or Other Shares
and, upon the written request, given within 20 days after delivery of any such
notice by the Company, of any such Purchaser to include in such registration
Registrable Shares (which request shall specify the number of Registrable
Shares proposed to be included in such registration), the Company shall use its
best efforts to cause all such Registrable Shares to be included in such
registration on the same terms and conditions as the securities otherwise
being sold in such registration; provided, however, that if the managing
underwriter advises the Company that the inclusion of all Registrable
Shares or Other Shares proposed to be included in such registration would
interfere with the successful marketing (including pricing) of Primary
Shares proposed to be registered by the Company, then the number of Primary
Shares, Registrable Shares and Other Shares proposed to be included in such
registration shall be included in the following order:

                           (i) first, the Primary Shares;

                           (ii) second, the Registrable Shares held by the
                  Purchasers, pro rata based upon the number of Restricted
                  Securities owned by each such Purchaser at the time of such
                  registration; and

                           (iii) third, the Other Shares.

         SECTION 5. Holdback Agreement.

         (a) If the Company at any time shall register shares of Common Stock
under the Securities Act in an underwritten offering pursuant to any
registration so long as the Requisite Purchasers agree in writing that this
holdback provision applies to such registration, then the Purchasers shall not
sell, make any short sale of, grant any option for the purchase of, or
otherwise dispose of any Restricted Securities (other than those Registrable
Shares included in such registration pursuant to Section 2, 3 or 4) without the
prior written consent of the Company for a period as shall be determined by the
managing underwriters, which period cannot begin more than 10 days prior to the
effectiveness of such Registration Statement and cannot last more than 180 days
after the effective date of such Registration Statement.

         (b) If the Company at any time pursuant to Sections 2, 3 or 4 of this
Agreement shall register under the Securities Act Registrable Shares held by
Purchasers for sale to the public pursuant to an underwritten offering, the
Company shall not, without the prior written consent of the Requisite
Purchasers, effect any public sale or distribution of securities similar to
those being registered or any securities convertible into or exercisable or
exchangeable for such securities, for such period as shall be determined by the
managing underwriters, which period shall not begin more than 10 days prior to
the effectiveness of the Registration Statement pursuant to which such public
offering shall be made and shall not last more than 180 days after the closing
of sale of shares pursuant to such Registration Statement.

         SECTION 6. Preparation and Filing. If and whenever the Company is
under an obligation pursuant to the provisions of this Agreement to use its
best efforts to effect the registration of any Registrable Shares, the Company
shall, as expeditiously as practicable:

                  (i) use its best efforts to cause a Registration Statement
         that registers such Registrable Shares to become and remain effective
         for a period of 90 days or until all of such Registrable Shares have
         been disposed of (if earlier);

                  (ii) furnish, at least five business days before filing a
         Registration Statement that registers such Registrable Shares, a
         Prospectus relating thereto and any amendments or supplements relating
         to such Registration Statement or Prospectus, to one counsel selected
         by CVCA (the "Purchasers' Counsel"), copies of all such documents
         proposed to be filed (it being understood that such five-business-day
         period need not apply to successive drafts of the same document
         proposed to be filed so long as such successive drafts are supplied to
         such counsel in advance of the proposed filing by a period of time
         that is customary and reasonable under the circumstances);

                  (iii) prepare and file with the Commission such amendments
         and supplements to such Registration Statement and the Prospectus used

         in connection therewith as may be necessary to keep such Registration
         Statement effective for at least a period of 90 days or until all of
         such Registrable Shares have been disposed of (if earlier) and to
         comply with the provisions of the Securities Act with respect to the
         sale or other disposition of such Registrable Shares;

                  (iv) notify the Purchasers' Counsel promptly in writing (A)
         of any comments by the Commission with respect to such Registration
         Statement or Prospectus, or any request by the Commission for the
         amending or supplementing thereof or for additional information with
         respect thereto, (B) of the issuance by the Commission of any stop
         order suspending the effectiveness of such Registration Statement or
         Prospectus or any amendment or supplement thereto or the initiation of
         any proceedings for that purpose and (C) of the receipt by the Company
         of any notification with respect to the suspension of the
         qualification of such Registrable Shares for sale in any jurisdiction
         or the initiation or threatening of any proceeding for such purposes;

                  (v) use its best efforts to register or qualify such
         Registrable Shares under such other securities or blue sky laws of
         such jurisdictions as any seller of Registrable Shares reasonably
         requests and do any and all other acts and things which may be
         reasonably necessary or advisable to enable such seller of
         Registrable Shares to consummate the disposition in such
         jurisdictions of the Registrable Shares owned by such seller;
         provided, however, that the Company will not be required to
         qualify generally to do business, subject itself to general
         taxation or consent to general service of process in any
         jurisdiction where it would not otherwise be required so to do but
         for this clause (v);

                  (vi) furnish to each seller of such Registrable Shares such
         number of copies of a summary Prospectus or other Prospectus,
         including a preliminary Prospectus, in conformity with the
         requirements of the Securities Act, and such other documents as such
         seller of Registrable Shares may reasonably request in order to
         facilitate the public sale or other disposition of such Registrable
         Shares;

                  (vii) use its best efforts to cause such Registrable Shares
         to be registered with or approved by such other governmental agencies
         or authorities as may be necessary by virtue of the business and
         operations of the Company to enable the seller or sellers thereof to
         consummate the disposition of such Registrable Shares;

                  (viii) notify on a timely basis each seller of such
         Registrable Shares at any time when a Prospectus relating to such
         Registrable Shares is required to be delivered under the Securities
         Act within the appropriate period mentioned in clause (i) of this
         Section 6 of the happening of any event as a result of which the
         Prospectus included in such Registration Statement, as then in
         effect, includes an untrue statement of a material fact or omits
         to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading in light
         of the circumstances then existing and, at the request of such
         seller, prepare and furnish to such seller a reasonable number of
         copies of a supplement to or an amendment of such Prospectus as
         may be necessary so that, as thereafter delivered to the offerees
         of such shares, such Prospectus shall not include 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 in light of the circumstances then
         existing;

                  (ix) make available for inspection by any seller of such
         Registrable Shares, any underwriter participating in any disposition
         pursuant to such Registration Statement and any attorney, accountant
         or other agent retained by any such seller or underwriter
         (collectively, the "Inspectors"), all pertinent financial,
         business and other records, pertinent corporate documents and
         properties of the Company (collectively, the "Records"), as shall
         be reasonably necessary to enable them to exercise their due
         diligence responsibility, and cause the Company's officers,
         directors and employees to supply all information (together with
         the Records, the "Information") reasonably requested by any such
         Inspector in connection with such Registration Statement (and any
         of the Information which the Company determines in good faith to
         be confidential, and of which determination the Inspectors are so
         notified, shall not be disclosed by the Inspectors unless (A) the
         disclosure of such Information is necessary to avoid or correct a
         misstatement or omission in the Registration Statement, (B) the
         release of such Information is ordered pursuant to a subpoena or
         other order from a court of competent jurisdiction, (C) such
         Information has been made generally available to the public, and
         (D) the seller of Registrable Shares agrees that it will, upon
         learning that disclosure of such Information is sought in a court
         of competent jurisdiction, give notice to the Company and allow
         the Company, at the Company's expense, to undertake appropriate
         action to prevent disclosure of the Information deemed
         confidential);

                  (x) use its best efforts to obtain from its independent
         certified public accountants a "cold comfort" letter in customary form
         and covering such matters of the type customarily covered by cold
         comfort letters;

                  (xi) use its best efforts to obtain, from its counsel, an
         opinion or opinions in customary form (which shall also be addressed
         to the Purchasers selling Registrable Shares in such registration);

                  (xii) provide a transfer agent and registrar (which may be
         the same entity and which may be the Company) for such Registrable
         Shares;

                  (xiii) issue to any underwriter to which any seller of
         Registrable Shares may sell shares in such offering certificates
         evidencing such Registrable Shares;

                  (xiv) list such Registrable Shares on any national securities
         exchange on which any shares of the Common Stock are listed or, if the
         Common Stock is not listed on a national securities exchange, use its
         best efforts to qualify such Registrable Shares for inclusion on the
         automated quotation system of the National Association of Securities
         Dealers, Inc. (the "NASD"), National Market System ("NMS"), or such
         other national securities exchange as the holders of a majority of
         such Registrable Shares shall request included in such registration;

                  (xv) otherwise use its best efforts to comply with all
         applicable rules and regulations of the Commission, and make available
         to its securityholders, as soon as reasonably practicable, earnings
         statements which need not be audited covering a period of 12 months
         beginning within three months after the effective date of the
         Registration Statement, which earnings statements shall satisfy the
         provisions of Section 11(a) of the Securities Act; and

                  (xvi) use its best efforts to take all other steps necessary
         to effect the registration of such Registrable Shares contemplated
         hereby.

         SECTION 7. Expenses. All expenses incurred by the Company in complying
with Section 6, including, without limitation, all registration and filing fees
(including all expenses incident to filing with the NASD), fees and expenses of
complying with securities and blue sky laws, printing expenses, fees and
expenses of the Company's counsel and accountants and fees and expenses of one
special legal counsel to the Purchasers selected by CVCA, shall be paid by the
Company; provided, however, that all underwriting discounts and selling
commissions applicable to the Registrable Shares shall not be borne by the
Company but shall be borne by the seller or sellers thereof, in proportion to
the number of Registrable Shares sold by such seller or sellers.

         SECTION 8. Indemnification.

         (a) In connection with any registration of any Registrable Shares
under the Securities Act pursuant to this Agreement, the Company shall
indemnify and hold harmless the seller of such Registrable Shares, each
underwriter, broker or any other Person acting on behalf of such seller, each
other Person, if any, who controls any of the foregoing Persons within the
meaning of the Securities Act and each Representative of any of the foregoing
Persons, against any losses, claims, damages or liabilities, joint or several,
to which any of the foregoing Persons may become subject under the Securities
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue statement
or alleged untrue statement of a material fact contained in the Registration
Statement under which such Registrable Shares were registered, any preliminary
Prospectus or final Prospectus contained therein, any amendment or supplement
thereto or any document incident to registration or qualification of any
Registrable Shares, or arise out of or are based upon 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, with respect to any
Prospectus, necessary to make the statements therein in light of the
circumstances under which they were made not misleading, or any violation by
the Company of the Securities Act or state securities or blue sky laws
applicable to the Company and relating to action or inaction required of the
Company in connection with such registration or qualification under such state
securities or blue sky laws, and the Company shall promptly reimburse such
seller, such underwriter, such broker, such controlling Person or such
Representatives for any legal or other expenses incurred by any of them in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company shall not be liable to
any such Person to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in said Registration Statement,
preliminary Prospectus, amendment, supplement or document incident to
registration or qualification of any Registrable Shares in reliance upon and in
conformity with written information furnished to the Company through an
instrument duly executed by such Person, or a Person duly acting on their
behalf, specifically for use in the preparation thereof; provided further,
however, that the foregoing indemnity agreement is subject to the condition
that, insofar as it relates to any untrue statement, allegedly untrue
statement, omission or alleged omission made in any preliminary Prospectus but
eliminated or remedied in the final Prospectus (filed pursuant to Rule 424 of
the Securities Act), such indemnity agreement shall not inure to the benefit of
any indemnified party from whom the Person asserting any loss, claim, damage,
liability or expense purchased the Registrable Shares which are the subject
thereof, if a copy of such final Prospectus had been timely made available to
such Indemnified Person and such final Prospectus was not delivered to such
Person with or prior to the written confirmation of the sale of such
Registrable Shares to such Person.

         (b) In connection with any registration of Registrable Shares under
the Securities Act pursuant to this Agreement, each seller of Registrable
Shares shall indemnify and hold harmless (in the same manner and to the same
extent as set forth in the paragraph (a) of this Section 8) the Company, each
underwriter or broker involved in such offering, each other seller of
Registrable Shares under such Registration Statement, each Person who controls
any of the foregoing Persons within the meaning of the Securities Act and any
Representative of the foregoing Persons with respect to any statement or
omission from such Registration Statement, any preliminary Prospectus or final
Prospectus contained therein, any amendment or supplement thereto or any
document incident to registration or qualification of any Registrable Shares,
if such statement or omission was made in reliance upon and in conformity with
written information furnished to the Company or such underwriter through an
instrument duly executed by such seller or a Person duly acting on their behalf
specifically for use in connection with the preparation of such Registration
Statement, preliminary Prospectus, final Prospectus, amendment or supplement;
provided, however, that the maximum amount of liability in respect of such
indemnification shall be limited, in the case of each seller of Registrable
Shares, to an amount equal to the net proceeds actually received by such seller
from the sale of Registrable Shares effected pursuant to such registration.

         (c) Promptly after receipt by an indemnified party of notice of the
commencement of any action involving a claim referred to in the preceding
paragraphs of this Section 8, such indemnified party will, if a claim in
respect thereof is made against an indemnifying party, give written notice to
the latter of the commencement of such action (provided however, that an
indemnified party's failure to give such notice in a timely manner shall only
relieve the indemnification obligations of an indemnifying party to the extent
such indemnifying party is prejudiced by such failure). In case any such action
is brought against an indemnified party, the indemnifying party will be
entitled to participate in and to assume the defense thereof, jointly with any
other indemnifying party similarly notified to the extent that it may wish,
with counsel reasonably satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be responsible
for any legal or other expenses subsequently incurred by the indemnified party
in connection with the defense thereof; provided, however, that if any
indemnified party shall have reasonably concluded that there may be one or more
legal or equitable defenses available to such indemnified party which are in
addition to or conflict with those available to the indemnifying party, or that
such claim or litigation involves or could have an effect upon matters beyond
the scope of the indemnity agreement provided in this Section 8, the
indemnifying party shall not have the right to assume the defense of such
action on behalf of such indemnified party and such indemnifying party shall
reimburse such indemnified party and any Person controlling such indemnified
party for that portion of the fees and expenses of any one lead counsel (plus
appropriate special and local counsel) retained by the indemnified party which
are reasonably related to the matters covered by the indemnity agreement
provided in this Section 8.

         (d) If the indemnification provided for in this Section 8 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, claim, damage or liability referred to herein, then the
indemnifying party, in lieu of indemnifying such indemnified party hereunder,
shall contribute to the amounts paid or payable by such indemnified party as a
result of such loss, claim, damage or liability 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 hand in connection with the
statements or omissions which resulted in such loss, claim, damage or liability
as well as any other relevant equitable considerations; provided, however, that
the maximum amount of liability in respect of such contribution shall be
limited, in the case of each seller of Registrable Shares, to an amount
equal to the net proceeds actually received by such seller from the sale of
Registrable Shares effected pursuant to such registration.  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 indemnified party and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement
or omission.

         (e) The indemnification and contribution provided for under this
Agreement will remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party and will survive the transfer of
securities.

         SECTION 9. Underwriting Agreement.

         (a) Notwithstanding the provisions of Sections 6 and 8, to the extent
that the Purchasers selling Registrable Shares in a proposed registration shall
enter into an underwriting or similar agreement, which agreement contains
provisions covering one or more issues addressed in such Sections of this
Agreement, the provisions contained in such Sections of this Agreement
addressing such issue or issues shall be of no force or effect with respect to
such registration, but this provision shall not apply to the Company if the
Company is not a party to the underwriting or similar agreement.

         (b) If any registration pursuant to Section 2 is requested to be an
underwritten offering, the Company shall negotiate in good faith to enter into
a reasonable and customary underwriting agreement with the underwriters
thereof. The Company shall be entitled to receive indemnities from lead
institutions, underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, to the
same extent as provided above with respect to information so furnished in
writing by such Persons specifically for inclusion in any Prospectus or
Registration Statement and to the extent customary given their role in such
distribution.

         (c) No Purchaser may participate in any registration hereunder that is
underwritten unless such Purchaser agrees to (i) sell such Purchaser's
Registrable Shares proposed to be included therein on the basis provided in any
underwriting arrangements acceptable to the Company and CVCA and (ii) as
expeditiously as possible, notify the Company of the occurrence of any event
concerning such Purchaser as a result of which the Prospectus relating to such
registration contains an untrue statement of a material fact or omits 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.

         SECTION 10. Suspension. Anything contained in this Agreement to the
contrary notwithstanding, the Company may (not more than once with respect to
each registration), by notice in writing to each holder of Registrable Shares
to which a Prospectus relates, require such holder to suspend, for up to 90
days (the "Suspension Period"), the use of any Prospectus included in a
Registration Statement filed under Section 2, 3 or 4 if a Material Transaction
exists that would require an amendment to such Registration Statement or
supplement to such Prospectus (including any such amendment or supplement made
through incorporation by reference to a report filed under Section 13 of the
Exchange Act). The period during which such Prospectus must remain effective
shall be extended by a period equal to the Suspension Period. The Company may
(but shall not be obligated to) withdraw the effectiveness of any Registration
Statement subject to this provision.

         SECTION 11. Information by Holder. Each holder of Registrable Shares
to be included in any registration shall furnish to the Company and the
managing underwriter such written information regarding such holder and the
distribution proposed by such holder as the Company or the managing underwriter
may reasonably request in writing and as shall be reasonably required in
connection with any registration, qualification or compliance referred to in
this Agreement.

         SECTION 12. Exchange Act Compliance. From and after the Registration
Date or such earlier date as a registration statement filed by the Company
pursuant to the Exchange Act relating to any class of the Company's securities
shall have become effective, the Company shall comply with all of the reporting
requirements of the Exchange Act (whether or not it shall be required to do so)
and shall comply with all other public information reporting requirements of
the Commission which are conditions to the availability of Rule 144 for the
sale of the Common Stock. The Company shall cooperate with each Purchaser in
supplying such information as may be necessary for such Purchaser to complete
and file any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of Rule 144.

         SECTION 13. No Conflict of Rights. The Company represents and warrants
to the Purchasers that the registration rights granted to the Purchasers hereby
do not conflict with any other registration rights granted by the Company. The
Company shall not, after the date hereof, grant any registration rights which
conflict with or impair, or have any priority over, the registration rights
granted hereby. In any underwritten public offering initiated pursuant to
Section 2(a), the managing underwriter shall be a nationally recognized
investment banking firm selected by the Company, and reasonably acceptable
to CVCA.

         SECTION 14. Termination. This Agreement shall terminate and be of no
further force or effect when there shall not be any Restricted Securities;
provided however, that Sections 7 and 8 shall survive the termination of this
Agreement.

         SECTION 15. Successors and Assigns. This Agreement shall bind and
inure to the benefit of the Company and the Purchasers and, subject to Section
16, their respective successors and assigns.

         SECTION 16. Assignment. Each Purchaser may assign its rights hereunder
to any purchaser from such Purchaser of Restricted Securities; provided,
however, that such purchaser shall, as a condition to the effectiveness of such
assignment, be required to execute a counterpart to this Agreement agreeing to
be treated as a Purchaser hereunder whereupon such purchaser shall have the
benefits of, and shall be subject to the restrictions contained in, this
Agreement as an Purchaser.

         SECTION 17. Entire Agreement. This Agreement contains the entire
agreement among the parties with respect to the subject matter hereof and
supersedes all prior arrangements or understandings with respect hereto.

         SECTION 18. Notices. All notices, requests, consents and other
communications hereunder to any party shall be deemed to be sufficient if

         SECTION 19. Modifications; Amendments; Waivers. The terms and
provisions of this Agreement may not be modified or amended, nor may any
provision applicable to the Purchasers be waived, except pursuant to a writing
signed by the Company and Requisite Purchasers; provided, however, that (i) any
such amendment, modification, or waiver that would adversely affect the rights
hereunder of any Purchaser, in its capacity as an Purchaser, without similarly
affecting the rights hereunder of all Purchasers of such class, in their
capacities as Purchasers of such class, shall not be effective as to such
Purchaser without its prior written consent and (ii) Schedule I to this
Agreement shall be deemed to be automatically amended from time to time to
reflect the addition to this Agreement of any Person identified in clause (ii)
of the definition of Purchaser without requiring the consent of any party, and

         SECTION 20. Headings. The headings of the various sections of this
Agreement have been inserted for convenience of reference only and shall not be
deemed to be a part of this Agreement.

         SECTION 21. Severability. It is the desire and intent of the parties
that the provisions of this Agreement be enforced to the fullest extent
permissible under the law and public policies applied in each jurisdiction in
which enforcement is sought. Accordingly, if any provision of this Agreement
would be held in any jurisdiction to be invalid, prohibited or unenforceable
for any reason, such provision, as to such jurisdiction, shall be ineffective,
without invalidating the remaining provisions of this Agreement or affecting
the validity or enforceability of such provision in any other jurisdiction.
Notwithstanding the foregoing, if such provision could be more narrowly drawn
so as not to be invalid, prohibited or unenforceable in such jurisdiction, it
shall, as to such jurisdiction, be so narrowly drawn, without invalidating the
remaining provisions of this Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction.

         SECTION 22. Governing Law; Etc. All questions concerning the
construction, interpretation and validity of this Agreement shall be governed
by and construed and enforced in accordance with the domestic laws of the State
of New York, without giving effect to any choice or conflict of law provision
or rule (whether in the State of New York or any other jurisdiction) that would
cause the application of the laws of any jurisdiction other than the State of
New York. In furtherance of the foregoing, the internal law of the State of New
York will control the interpretation and construction of this Agreement, even
