ITEM 8.01.    OTHER EVENTS.

         Effective as of August 9, 2004, we agreed to (i) issue approximately
29,841 shares of Series B-1 Convertible Preferred Stock, (ii) issue
approximately 40,822 shares of Common Stock, and (iii) pay approximately
$225,000 in cash in exchange for the cancellation of all outstanding principal
and accrued and unpaid interest under certain promissory notes we issued in
2003.

         In addition, effective as of August 9, 2004, we issued approximately
7,916 shares of Series B-1 Convertible Preferred Stock at a cash price per share
of $60.00 to investors, including James D. Durham, our Chairman and Chief
Executive Officer, who purchased 4,166 shares of Series B-1 Convertible
Preferred Stock.

         The holders of the Series B-1 Convertible Preferred Stock will be
entitled to receive a dividend on each of September 30, 2004, December 31, 2004,
March 31, 2005, June 30, 2005, September 30, 2005 and December 31, 2005 in an
amount equal to 1.5 shares of Common Stock for each share of outstanding Series
B-1 Convertible Preferred Stock held by them. In the event of any liquidation or
winding up of Crdentia Corp., the holders of the Series B-1 Convertible
Preferred Stock will be entitled to receive in preference to the holders of
Common Stock an amount equal to their initial purchase price plus any declared
but unpaid dividends and any remaining liquidation proceeds will thereafter be
distributed on a pro rata basis to the holders of the Series B-1 Convertible
Preferred Stock (on an as-if-converted into Common Stock basis), Common Stock
and any other series of Preferred Stock expressly entitled to participate in
such distribution, until the holders of Series B-1 Convertible Preferred Stock
shall have received, in the aggregate, an amount equal to five times the amount
of their purchase price. Unless previously voluntarily converted prior to such
time, the Series B-1 Convertible Preferred Stock will be automatically converted
into Common Stock at an initial conversion ratio of one hundred (100) shares of
Common Stock for each share of Series B-1 Convertible Preferred Stock upon the
earlier of (i) the closing of an underwritten public offering of our Common
Stock pursuant to a registration statement under the Securities Act of 1933, as
amended, with aggregate net proceeds of at least $25 million, or (ii) the date
specified by written consent or agreement of the holders of a majority of the
then outstanding shares of Series B-1 Convertible Preferred Stock. The
description of the foregoing rights, preferences and privileges of the Series
B-1 Convertible Preferred Stock is qualified in its entirety by the Certificate
of Designations, Preferences and Rights of Series B-1 Preferred Stock filed with
the Secretary of State of the State of Delaware on August 9, 2004 and filed as
Exhibit 4.1 to this report on Form 8-K.

         In addition, the holders of such shares of Series B-1 Convertible
Preferred Stock will be entitled to the registration rights set forth in the
Registration Rights Agreement dated August 9, 2004 by and among us and the
investors listed on Schedule A thereto, a copy of which is filed as Exhibit 4.2

               CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS

                                       OF

                           SERIES B-1 PREFERRED STOCK

                                       OF

                                 CRDENTIA CORP.

                         ------------------------------

                             Pursuant to Section 151
             of the General Corporation Law of the State of Delaware
                        ---------------------------------

                  Crdentia Corp. (the "CORPORATION"), a corporation organized
and existing under the General Corporation Law of the State of Delaware (the
"DGCL"), does hereby certify that pursuant to the provisions of Section 151 of
the DGCL, the Board of Directors of the Corporation, by an action by unanimous
written consent dated as of August 3, 2004, adopted the following resolution,
which resolution remains in full force and effect as of the date hereof:

                  WHEREAS, the Board of Directors of the Corporation is
authorized, within the limitations and restrictions stated in the Corporation's
Amended and Restated Certificate of Incorporation (the "CHARTER"), to fix by
resolution or resolutions the designation of each class or series of Preferred
Stock (the "PREFERRED Stock") and the voting powers, and any designations,
preferences, and relative, participating, optional or other special rights of
any such class or series of Preferred Stock, as well as such other provisions
with regard to redemption, dividends, conversion or exchange, and any
qualifications or restrictions thereof or such other subjects or matters as
shall be stated and expressed in the resolution or resolutions providing for the
issue of such stock adopted by the Board of Directors; and

                  WHEREAS, it is the desire of the Board of Directors of the
Corporation, pursuant to such authority, to authorize and fix the terms of the
series of Preferred Stock designated as Series B-1 Preferred Stock (the "SERIES
B-1 PREFERRED STOCK").

                  NOW, THEREFORE, BE IT RESOLVED, that the terms and provisions
of such series and all other right or preferences granted to or imposed upon
such series or the holders thereof are as herein set forth:

                  Section 1. DESIGNATION AND AMOUNT. The shares of such series
shall be designated as "Series B-1 Preferred Stock" (the "SERIES B-1 PREFERRED
STOCK") and the number of shares constituting the Series B-1 Preferred Stock
shall be One Hundred Thousand (100,000), $0.0001 par value. Such number may be
increased or decreased by resolution of the Board of Directors of the
Corporation; provided, however, that no decrease shall reduce the number of
shares of Series B-1 Preferred Stock to a number less than the number of shares
then outstanding plus the number of shares reserved for issuance upon the
exercise of outstanding options, rights or warrants or upon the conversion of
any outstanding securities issued by the Corporation convertible or exercisable
into Series B-1 Preferred Stock.


<PAGE>

                  Section 2. DIVIDENDS AND DISTRIBUTIONS. Subject to the rights
of the holders of any shares of any series of Preferred Stock (or any similar
stock) expressly ranking senior to, or PARI PASSU with, the Series B-1 Preferred
Stock with respect to dividends, each holder of a share of Series B-1 Preferred
Stock, in preference to the holders of shares of Common Stock, par value $0.0001
per share (the "COMMON STOCK"), of the Corporation, and of any other junior
stock, shall be entitled to receive, when declared by the Board of Directors out
of funds legally available for the purpose, a dividend of 1.5 shares of Common
Stock (subject to adjustment as described below) on each of September 30, 2004,
December 31, 2004, March 31, 2005, June 30, 2005, September 30, 2005 and
December 31, 2005 (each, a "DESIGNATED DIVIDEND DATE"). In the event of an
automatic conversion of the Series B-1 Preferred Stock pursuant to Section 4(b)
below prior to the next scheduled Designated Dividend Date, if any, the Company
shall immediately prior to such automatic conversion pay a dividend on each
share of Series B-1 Preferred Stock of 1.5 shares of Common Stock (subject to
adjustment as described below). In addition, if any cash dividend is declared on
shares of Common Stock, a dividend shall be paid out of legally available funds
on each share of Series B-1 Preferred Stock equal to the consideration that each
such share would have received had such share been converted into Common Stock
immediately prior to the record date fixed for such dividend. The dividend of
1.5 shares of Common Stock described herein shall be (i) increased or decreased
in proportion to the increase or decrease in the Conversion Ratio (as defined in
Section 4(a)) effected pursuant to Sections 4(d)(iii) or (iv) and (ii) adjusted
for stock splits, dividends, recapitalizations and the like of the Series B-1
Preferred Stock.

                  Section 3. LIQUIDATION PREFERENCE.

                           (a) Subject to the rights of holders of any class of
capital stock or series thereof expressly ranking senior to, or PARI PASSU with,
the Series B-1 Preferred Stock, upon any voluntary or involuntary liquidation,
dissolution or winding up of the affairs of the Corporation, the holder of each
share of the Series B-1 Preferred Stock then outstanding shall be entitled to be
paid out of the assets of the Corporation available for distribution to its
stockholders, prior to and in preference to any distribution of any assets of
the Corporation to the holders of the Common Stock or any other junior stock by
reason of their ownership thereof, an amount equal to $60.00 (as adjusted for
stock splits, stock dividends, recapitalizations and the like of the Series B-1
Preferred Stock) for each outstanding share of Series B-1 Preferred Stock, plus
declared but unpaid dividends on such share. If the assets of the Corporation
are not sufficient to pay in full the payments payable to the holders of
outstanding shares of Series B-1 Preferred Stock upon the liquidation,
dissolution or winding up of the affairs of the Corporation, then the holders of
all such shares shall share ratably with all other holders of shares of Series
B-1 Preferred Stock in such distribution of assets in proportion to the
Liquidation Preference of the respective shares.

                           (b) Upon completion of the distribution required by
subsection (a) of this Section 3 and any other distribution that may be required
with respect to series of Preferred Stock that may from time to time come into
existence, all of the remaining assets of this Corporation available for
distribution to stockholders shall be distributed among the holders of Series
B-1 Preferred Stock, Common Stock and any other series of Preferred Stock
expressly entitled to participate, pro rata based on the number of shares of
Common Stock held by each (assuming conversion of all shares of Series B-1
Preferred Stock); provided, however, that the holders of Series B-1 Preferred
Stock shall not be entitled to further participate in any distribution of the
remaining assets of this Corporation pursuant to this Section 3(b) following
receipt by such holders of aggregate distributions pursuant to this Section 3
equal to $300.00 per share (as adjusted for stock splits, stock dividends,
recapitalizations and the like on the Series B-1 Preferred Stock).


                                       2
<PAGE>

                           (c) The merger, consolidation or acquisition of the
Corporation into or with or by another entity or person which results in the
exchange of outstanding shares of the Corporation for securities or other
consideration issued or paid or caused to be issued or paid by such other person
or entity or affiliate of such entity (except if such merger, consolidation or
acquisition does not result in the transfer of more than fifty percent (50%) of
the voting securities of the Corporation's stock or in which the holders of the
voting securities of the Corporation immediately prior to the transaction
continue to hold not less than 50% of the voting securities of the resulting
entity after the transaction) or the sale of all or substantially all the assets
of the Corporation shall be deemed to be a liquidation, dissolution or winding
up of the Corporation for purposes of this section. The amount deemed
distributed to the holders of Series B-1 Preferred Stock upon any such merger or
consolidation shall be the cash or the value of the property, rights and/or
securities distributed to such holders by the acquiring person, firm or other
entity. The value of such property, rights or other securities shall be
determined in good faith by the Board of Directors of the Corporation.

                  Section 4. CONVERSION. The holders of the Series B-1 Preferred
Stock shall have conversion rights as follows (the "CONVERSION RIGHTS"):

                           (a) RIGHT TO CONVERT. Each share of Series B-1
Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such share into such number of fully paid
and nonassessable shares of Common Stock as is determined by dividing (i) $60.00
(as adjusted proportionally for stock splits, stock dividends, recapitalizations
and the like of the Series B-1 Preferred Stock, the "ORIGINAL ISSUANCE PRICE")
by (ii) the Conversion Price (such ratio being referred to as the "CONVERSION
RATIO"). The initial Conversion Price for the Series B-1 Preferred Stock shall
be $0.60; PROVIDED, HOWEVER, that the Conversion Price for the Series B-1
Preferred Stock shall be subject to adjustment as set forth in Section 4(d).
Such conversion shall be deemed to have been made immediately prior to the close
of business on the date of delivery of notice by the holder to the Corporation
stating that such holder desires to convert the Series B-1 Preferred Stock as
contemplated by this Section 4(a), and the person or persons entitled to receive
the shares of Common Stock issuable upon such conversion shall be treated for
all purposes as the record holder or holders of such shares of Common Stock as
of such date.

                           (b) AUTOMATIC CONVERSION. Each share of Series B-1
Preferred Stock shall automatically be converted into shares of Common Stock at
the Conversion Ratio at the time in effect for such Series B-1 Preferred Stock
upon the earlier of (i) the closing of an underwritten public offering of the
Corporation's Common Stock pursuant to a registration statement under the
Securities Act of 1933, as amended, with aggregate net proceeds to the
Corporation in excess of twenty-five million dollars ($25,000,000) or (ii) the
date specified by written consent or agreement of the holders of a majority of
the then outstanding shares of Series B-1 Preferred Stock, voting together as a
class.. All holders of record of shares of Series B-1 Preferred Stock will be
given written notice of an automatic conversion of all shares of Series B-1
Preferred Stock pursuant to this Section 4(b) (the "CONVERSION NOTICE"). Within
ten (10) days following receipt of such Conversion Notice, each holder of Series
B-1 Preferred Stock shall surrender the certificate or certificates representing
all of such holder's Series B-1 Preferred Stock, duly endorsed, at the office of
this Corporation or of any transfer agent for the Series B-1 Preferred Stock.

                                       3
<PAGE>

This Corporation shall, as soon as practicable thereafter, issue and deliver at
such office to such holder of Series B-1 Preferred Stock, or to the nominee or
nominees of such holder, a certificate or certificates for the number of shares
of Common Stock to which such holder shall be entitled as aforesaid. Such
conversion shall be deemed to have been made immediately prior to the close of
business on the date of delivery of the Conversion Notice, and the person or
persons entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock as of such date.

                           (c) MECHANISM OF CONVERSION. Before any holder of
Series B-1 Preferred Stock pursuant to Section 4(a) above, shall be entitled to
convert the same into shares of Common Stock, the holder shall surrender the
certificate or certificates therefor, duly endorsed, at the office of this
Corporation or of any transfer agent for the Series B-1 Preferred Stock, and
shall give written notice to this Corporation at its principal corporate office,
of the election to convert the same and shall state therein the name or names in
which the certificate or certificates for shares of Common Stock are to be
issued. Upon conversion of only a portion of the number of shares covered by a
certificate representing shares of Series B-1 Preferred Stock surrendered for
conversion, the Corporation shall issue and deliver to or upon the written order
of the holder of the certificate so surrendered for conversion, at the expense
of the Corporation, a new certificate covering the number of shares of Series
B-1 Preferred Stock representing the unconverted portion of the certificate so
surrendered. This Corporation shall, as soon as practicable thereafter, issue
and deliver at such office to such holder of Series B-1 Preferred Stock, or to
the nominee or nominees of such holder, a certificate or certificates for the
number of shares of Common Stock to which such holder shall be entitled as
aforesaid. Such conversion shall be deemed to have been made immediately prior
to the close of business on the date of such surrender of the shares of Series
B-1 Preferred Stock to be converted, and the person or persons entitled to
receive the shares of Common Stock issuable upon such conversion shall be
treated for all purposes as the record holder or holders of such shares of
Common Stock as of such date.

                           (d) CONVERSION PRICE ADJUSTMENTS OF PREFERRED STOCK.
The Conversion Prices of the Series B-1 Preferred Stock shall be subject to
adjustment from time to time as follows:

                                    (i) (A) If this Corporation shall issue,
after the date upon which any shares of Series B-1 Preferred Stock were first
issued (the "PURCHASE DATE" with respect to such series), any Additional Stock
(as defined below) without consideration or for a consideration per share less
than the Conversion Price in effect immediately prior to the issuance of such
Additional Stock, the Conversion Price for the Series B-1 Preferred Stock in
effect immediately prior to each such issuance shall forthwith (except as
otherwise provided in this Section 4(d)(i)) be adjusted to a price equal to the
price paid per share for such Additional Stock.


                                       4
<PAGE>

                                            (B) No adjustment of the Conversion
Price for any Series B-1 Preferred Stock shall be made in an amount less than
one cent per share, provided that any adjustments that are not required to be
made by reason of this sentence shall be carried forward and shall be taken into
account in any subsequent adjustment. Except to the limited extent provided for
in Sections 4(d)(i)(E)(3) and 4(d)(i)(E)(4), no adjustment of such Conversion
Price pursuant to this Section 4(d)(i) shall have the effect of increasing the
Conversion Price above the Conversion Price in effect immediately prior to such
adjustment.

                                            (C) In the case of the issuance of
Additional Stock for cash, the consideration shall be deemed to be the amount of
cash paid therefor before deducting any reasonable discounts, commissions or
other expenses allowed, paid or incurred by this Corporation for any
underwriting or otherwise in connection with the issuance and sale thereof.

                                            (D) In the case of the issuance of
the Additional 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
as determined by the Board of Directors irrespective of any accounting
treatment.

                                            (E) In the case of the issuance
(whether before, on or after the applicable Purchase Date) 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, the
following provisions shall apply for all purposes of this Section 4(d)(i) and
Section 4(d)(ii):

                                                     (1) The aggregate maximum
number of shares of Common Stock deliverable upon exercise (assuming the
satisfaction of any conditions to exercisability, including, without limitation,
the passage of time) 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 Sections 4(d)(i)(C) and 4(d)(i)(D)), if
any, received by this Corporation upon the issuance of such options or rights
plus the minimum exercise price provided in such options or rights for the
Common Stock covered thereby.

                                                     (2) The aggregate maximum
number of shares of Common Stock deliverable upon conversion of, or in exchange
(assuming the satisfaction of any conditions to convertibility or
exchangeability, including, without limitation, the passage of time) 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 were issued or such options or rights were
issued and for a consideration equal to the consideration, if any, received by
this Corporation for any such securities and related options or rights
(excluding any cash received on account of accrued interest or accrued
dividends), plus the minimum additional consideration, if any, to be received by
this 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 Sections 4(d)(i)(C) and 4(d)(i)(D)).

                                                     (3) In the event of any
change in the number of shares of Common Stock deliverable or in the
consideration payable to this Corporation upon exercise of such options or
rights or upon conversion of or in exchange for such convertible or exchangeable
securities, including, but not limited to, a change resulting from the
antidilution provisions thereof, the Conversion Price of the Series B-1
Preferred Stock, to the extent in any way affected by or computed using such
options, rights or securities, shall be recomputed to reflect such change, but
no further adjustment shall be made for the actual issuance of Common Stock or
any payment of such consideration upon the exercise of any such options or
rights or the conversion or exchange of such securities.

                                                     (4) Upon 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 of the Series B-1 Preferred
Stock, to the extent in any way affected by or computed using such options,
rights or securities or options or rights related to such securities, shall be
recomputed to reflect the issuance of only the number of shares of Common Stock
(and convertible or exchangeable securities that remain in effect) 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.

                                                     (5) The number of shares of
Common Stock deemed issued and the consideration deemed paid therefor pursuant
to Sections 4(d)(i)(E)(1) and 4(d)(i)(E)(2) shall be appropriately adjusted to
reflect any change, termination or expiration of the type described in either
Section 4(d)(i)(E)(3) or 4(d)(i)(E)(4).

                                    (ii) "Additional Stock" shall mean any
shares of Common Stock issued (or deemed to have been issued pursuant to Section
4(d)(i)(E)) by this Corporation after the applicable Purchase Date other than:

                                            (A) shares of Common Stock issued
pursuant to a transaction described in Section 4(d)(iii) hereof;

                                            (B) shares of Common Stock issued or
deemed issued to employees, consultants, officers, directors or vendors of this
Corporation directly or pursuant to a stock option plan and/or agreement,
restricted stock purchase plan or other agreement approved by the Board of
Directors of this Corporation;

                                            (C) shares of Common Stock issued or
issuable (I) in a bona fide public offering under the Act or (II) upon exercise
of warrants or rights granted to underwriters in connection with such a public
offering;


                                       6
<PAGE>

                                            (D) shares of Common Stock issued
pursuant to the conversion or exercise of convertible or exercisable securities
outstanding as of the date hereof or subsequently issued pursuant to this
Section 4(d)(ii);

                                            (E) shares of Common Stock issued or
issuable in connection with a bona fide business acquisition of or by this
Corporation, whether by merger, consolidation, sale of assets, sale or exchange
of stock or otherwise, each as approved by the Board of Directors of this
Corporation; or

                                            (F) shares of Common Stock issued or
issuable to persons or entities in connection with strategic alliances or to
strategic corporate partners or to parties that are providing the Corporation
with equipment loans, real property leases, loans, credit lines, guarantees of
indebtedness, licensing agreements, consulting agreements, cash price reductions
or similar transactions.

                                    (iii) In the event this Corporation should
at any time or from time to time after the Purchase Date fix a record date for
the effectuation of a split or subdivision of the outstanding shares of Common
Stock or the determination of holders of Common Stock entitled to receive a
dividend or other distribution payable in additional shares of Common Stock or
other securities or rights convertible into, or entitling the holder thereof to
receive directly or indirectly, additional shares of Common Stock (hereinafter
referred to as "COMMON STOCK EQUIVALENTS") without payment of any consideration
by such holder for the additional shares of Common Stock or the Common Stock
Equivalents (including the additional shares of Common Stock issuable upon
conversion or exercise thereof), then, as of such record date (or the date of
such dividend distribution, split or subdivision if no record date is fixed),
the Conversion Price of the Series B-1 Preferred Stock shall be appropriately
decreased so that the number of shares of Common Stock issuable on conversion of
each share of such series shall be increased in proportion to such increase in
the aggregate number of shares of Common Stock outstanding and those issuable
with respect to such Common Stock Equivalents.

                                    (iv) If the number of shares of Common Stock
outstanding at any time after the Purchase Date is decreased by a combination of
the outstanding shares of Common Stock, then, following the record date of such
combination, the Conversion Price for the Series B-1 Preferred Stock shall be
appropriately increased so that the number of shares of Common Stock issuable on
conversion of each share of such series shall be decreased in proportion to such
decrease in outstanding shares.

                           (e) OTHER DISTRIBUTIONS. In the event this
Corporation shall declare a distribution payable in securities of other persons,
evidences of indebtedness issued by this Corporation or other persons, assets
(excluding cash dividends) or options or rights not referred to in Section
4(d)(iii), then, in each such case for the purpose of this Section 4(e), the
holders of the Series B-1 Preferred Stock shall be entitled to a proportionate
share of any such distribution as though they were the holders of the number of
shares of Common Stock of this Corporation into which their shares of the Series
B-1 Preferred Stock are convertible as of the record date fixed for the
determination of the holders of Common Stock of this Corporation entitled to
receive such distribution.

<PAGE>

                           (f) RECAPITALIZATIONS. If at any time or from time to
time there shall be a recapitalization of the Common Stock (other than a
subdivision, combination or merger or sale of assets transaction provided for
elsewhere in Section 3 or this Section 4) provision shall be made so that the
holders of the Series B-1 Preferred Stock shall thereafter be entitled to
receive upon conversion of the Series B-1 Preferred Stock the number of shares
of stock or other securities or property of this Corporation or otherwise, to
which a holder of the number of shares of Common Stock deliverable upon
conversion of the Series B-1 Preferred Stock held by such holder would have been
entitled on such recapitalization. In any such case, appropriate adjustment
shall be made in the application of the provisions of this Section 4 with
respect to the rights of the holders of each series of Preferred Stock after the
recapitalization to the end that the provisions of this Section 4 (including
adjustment of the Conversion Price then in effect and the number of shares
purchasable upon conversion of the Series B-1 Preferred Stock) shall be
applicable after that event as nearly equivalent as may be practicable.

                           (g) NO IMPAIRMENT. This Corporation will not, by
amendment of its Amended and Restated Certificate of Incorporation or through
any reorganization, recapitalization, 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 this Corporation, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 4 and in the
taking of all such action as may be necessary or appropriate in order to protect
the Conversion Rights of the holders of the Series B-1 Preferred Stock against
impairment.

                           (h) NO FRACTIONAL SHARES. No fractional shares shall
be issued upon the conversion of any share or shares of the Series B-1 Preferred
Stock. In lieu of any fractional shares to which the holder would otherwise be
entitled, this Corporation shall pay cash equal to such fraction multiplied by
the then fair market value of a share of Common Stock as determined in good
faith by the Board of Directors. The number of shares of Common Stock to be
issued upon such conversion shall be determined on the basis of the total number
of the Series B-1 Preferred Stock the holder is at the time converting into
Common Stock and the number of shares of Common Stock issuable upon such
aggregate conversion.

                           (i) NOTICES OF RECORD DATE. In the event of any
taking by this Corporation of a record of the holders of any class of securities
for the purpose of determining the holders thereof who are entitled to receive
any dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, this
Corporation shall mail to each holder of the Series B-1 Preferred Stock, at
least twenty (20) days prior to the date specified therein, a notice specifying
the date on which any such record is to be taken for the purpose of such
dividend, distribution or right, and the amount and character of such dividend,
distribution or right.

<PAGE>

                           (j) RESERVATION OF STOCK ISSUABLE UPON CONVERSION.
This Corporation shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the conversion of the shares of Series B-1 Preferred Stock, such
number of its shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all outstanding shares of the Series B-1 Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock shall not be sufficient to effect the conversion of all then outstanding
shares of the Series B-1 Preferred Stock, in addition to such other remedies as
shall be available to the holder of such Preferred Stock, this Corporation will
take such corporate action as may, in the opinion of its counsel, be necessary
to increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purposes, including, without limitation,
engaging in best efforts to obtain the requisite stockholder approval of any
necessary amendment to this Certificate.

                           (k) NOTICES. Any notice required by the provisions of
this Section 4 to be given to the holders of shares of the Series B-1 Preferred
Stock shall be deemed given if deposited in the United States mail, postage
prepaid, and addressed to each holder of record at his address appearing on the
books of this Corporation.

                  Section 5. REDEMPTION. Neither the Corporation nor the holders
of Series B-1 Preferred Stock, shall have the unilateral right to call or redeem
or cause to have called or redeemed any shares of the Series B-1 Preferred
Stock.

                  Section 6. VOTING RIGHTS. The holder of each share of Series
B-1 Preferred Stock shall have the right to one vote for each share of Common
Stock into which such Series B-1 Preferred Stock could then be converted;
provided that, in determining the number of votes represented by each share, the
Conversion Price shall not be adjusted for any shares of Common Stock for which
a record date for their distribution has been fixed, but as to which the
distribution had not been made at the time of the vote, and with respect to such
vote, such holder shall have full voting rights and powers equal to the voting
rights and powers of the holders of Common Stock, and shall be entitled,
notwithstanding any provision hereof, to notice of any stockholders' meeting in
accordance with the Bylaws of this Corporation, and shall be entitled to vote,
together with holders of Common Stock, with respect to any question upon which
holders of Common Stock have the right to vote. Fractional votes shall not,
however, be permitted and any fractional voting rights available on an
as-converted basis (after aggregating all shares into which shares of Series B-1
Preferred Stock held by each holder could be converted) shall be rounded to the
nearest whole number (with one-half being rounded upward). In addition, no
series of Preferred Stock ranking prior to or superior to the Series B-1
Preferred Stock with respect to dividends, voting rights or liquidation
preference shall be created by this Corporation without the prior approval of a
majority of the outstanding interests of the Series B-1 Preferred Stock voting
as a single class.

                  Section 7. STATUS OF CONVERTED STOCK. In the event any shares
of Series B-1 Preferred Stock shall be converted pursuant to Section 4 hereof,
the shares so converted shall be canceled and shall not be issuable by the
Corporation, and the Corporation may take such appropriate corporate action as
may be necessary to reduce the number of authorized shares of the Corporation's
capital stock.

                  Section 8. RANK. Except as otherwise provided in the terms of
any other class of the Corporation's Preferred Stock, the Series B-1 Preferred
Stock shall rank, with respect to the payment of dividends and the distribution
of assets, PARI PASSU with the Corporation's Series A Preferred Stock and Series
B Preferred Stock and junior to all other series of any other class of the
Corporation's Preferred Stock.

               (g) The number of shares of "REGISTRABLE SECURITIES THEN
OUTSTANDING" shall be determined by the number of shares of Common Stock
outstanding which are, and the number of shares of Common Stock issuable

               (h) The term "SEC" shall mean the Securities and Exchange

          1.2 REQUESTED REGISTRATION.

               (a) REQUEST FOR REGISTRATION. If the Company shall receive from
the Holders of sixty-six and two-third percent (66 2/3%) or more of the
Registrable Securities then outstanding (the "INITIATING HOLDERS") a written
request that the Company file a registration statement in accordance with the
Act covering the registration on a continuous basis pursuant to Rule 415 under
the Act, or any successor rule or regulation ("RULE 415") of all or part of the
Registrable Securities then held by such Holders, the Company shall:

                    (i) within ten (10) days of the receipt thereof, give
written notice of the proposed registration, qualification or compliance to all
other Holders; and

                    (ii) use its reasonable and diligent efforts to effect, as
soon as practicable, the registration under the Act of all such Holders'
Registrable Securities as are specified in such request, together with such
portion of the Registrable Securities of any other Holder or Holders joining in
such request as are specified in a written notice given within fifteen (15) days
after receipt of written notice from the Company; PROVIDED, HOWEVER, that the
Company shall not be obligated to take any action to effect any such
registration pursuant to this Section 1.2, (A) after the Company has effected
one (1) registration under this SECTION 1.2; (B) if less than sixty-six and
two-third percent (66 2/3%) of the then outstanding Registrable Securities will
be registered, or (C) if the Holders propose to sell the Registrable Securities

$30,000,000.

                    (b) REGISTRATION STATEMENTS. Any registration statement
filed pursuant to this SECTION 1.2 shall be on Form S-3, or if Form S-3 is not
available, Form S-1 or other appropriate form permitting registration of the
Registrable Securities for resale by the Holders.

                                      -2-
<PAGE>

                    (c) UNDERWRITING. Notwithstanding any other provision of
this SECTION 1.2, the Company shall not be required to file a registration
statement pursuant to this SECTION 1.2 unless the Holders intend to distribute
all of the Registrable Securities covered by the registration statement filed
pursuant to this SECTION 1.2 by means of an underwriter or underwriters of
national standing reasonably approved by the Company. The Company (together with
all Holders proposing to distribute their securities pursuant such registration)
shall enter into an underwriting agreement in customary form with the
underwriter or underwriters selected by the Holders (and reasonably approved by
the Company). Notwithstanding any other provision of this SECTION 1.2, if the
underwriter advises the Holders in writing that marketing factors require a
limitation of the number of shares to be underwritten, then the Holders
requesting the underwriting shall so advise all Holders of Registrable
Securities, and the number of shares included in the underwriting shall be
allocated among the Holders of Registrable Securities requesting registration in
proportion, as nearly as practicable, to the total number of Registrable
Securities held by such Holders at the time of the request for an underwriting.
If any Holder disapproves of the terms of the underwriting, such Holder may
elect to withdraw from such underwritten offering by written notice to the
Company, the underwriter and the other Holders whose shares are being included
in the underwriting.

                    (d) RIGHTS IN ADDITION TO OTHER RIGHTS. The rights under
this SECTION 1.2 are in addition to, and not affected by, the Holders' exercise
of any registration rights contained in SECTION 1.3.

          1.3 COMPANY REGISTRATION. If (but without any obligation to do so) the
Company proposes to register any of its stock or other securities under the Act
in connection with the public offering of such securities solely for cash (other
than a registration effected at the request of one or more stockholders of the
Company (including, without limitation, any registration effected pursuant to a
contractual right of one or more stockholders to request a registration) or
relating solely to the sale of securities to participants in a Company employee
benefit plan or corporate reorganization or other transaction covered by Rule
145 promulgated under the Act, or a registration on any form which does not
permit secondary sales or include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given within twenty (20) days after mailing of such notice by the Company
in accordance with SECTION 2.6 hereof, the Company shall, subject to the
provisions of SECTION 1.7 hereof, cause to be registered under the Act all of
the Registrable Securities that each such Holder has requested to be registered.

          1.4 OBLIGATIONS OF THE COMPANY. Whenever required under this SECTION 1
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

               (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its reasonable and diligent
efforts to cause such registration statement to become effective, and keep such
registration statement effective (i) in the case of a registration statement
filed pursuant to SECTION 1.2, during the Effectiveness Period (as hereinafter

                                      -3-
<PAGE>

defined) or (ii) in the case of a registration statement filed pursuant to
SECTION 1.3, upon the request of the Holders of a majority of the Registrable
Securities registered thereunder, for up to one hundred twenty (120) days or, if
earlier, the date on which the distribution contemplated in the registration
statement has been completed. As used herein, the term "EFFECTIVENESS PERIOD"
shall mean until the earlier of (i) the termination of the rights set forth in
this Agreement in accordance with SECTION 1.14 or (ii) all of the Registrable
Securities covered by the registration having been sold or a subsequent
registration statement covering any unsold Registrable Securities having been
declared effective.

               (b) Provide, at least three (3) business days prior to filing,
any registration statement and included prospectus (including each preliminary
prospectus and any amendments or supplements thereto) prepared in conformity
with the requirements of the Act in connection with SECTIONS 1.2 and 1.3 (the
"REGISTRATION Materials") to the Holders and their respective counsel for review
and comment, if any.

               (c) Prepare and file with the SEC such amendments and supplements
to such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

               (d) Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents and Registration Materials as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by them that are included in such registration.

               (e) Use its reasonable and diligent efforts to register and
qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders; PROVIDED, HOWEVER, that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do
business or to file a general consent to service of process in any such states
or jurisdictions.

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

               (g) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event the result
of which causes the prospectus included in such registration statement, as then
in effect, to 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; and
thereafter, the Company will use reasonable efforts to amend or supplement such
prospectus in order to cause such prospectus not to include any 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
circumstances then existing; PROVIDED, HOWEVER, that upon such notification by
the Company, the Holders will not offer or sell Registrable Securities until the
Company has notified the Holders that it has prepared a supplement or amendment
to such prospectus and delivered copies of such supplement or amendment to the
Holders (it being understood and agreed by the Company that the foregoing
proviso shall in no way diminish or otherwise impair the Company's obligations
to prepare a prospectus amendment or supplement as above provided in this
SECTION 1.4(g)).

               (h) Use its reasonable and diligent efforts, if a registration
statement under SECTION 1.2 ceases to be effective for any reason at any time
during the Effectiveness Period (other than because of the sale of all of the
Registrable Securities registered thereunder or pursuant to the Company's
exercise of the Suspension Right (as hereinafter defined)), to (i) obtain the
prompt withdrawal of any order suspending the effectiveness thereof, and (ii)
amend the registration statement in a manner reasonably expected to obtain the
withdrawal of the order suspending the effectiveness of the shelf registration
or file an additional registration statement covering all of the unsold
Registrable Securities (a "SUBSEQUENT REGISTRATION STATEMENT"). If a Subsequent
Registration Statement is filed, the Company will use its reasonable and
diligent efforts to cause the Subsequent Registration Statement to be declared
effective as soon as practicable and to keep such Subsequent Registration
Statement continuously effective until the end of the Effectiveness Period. The
requirements of this SECTION 1.4(H) that the Company file additional
registration statements shall not be affected by the provisions set forth in
SECTION 1.2 that the Company is only required to file one registration statement
under SECTION 1.2.

               (i) Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed.

               (j) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

               (k) Use its reasonable and diligent efforts to furnish, at the
request of any Holder requesting registration of Registrable Securities pursuant
to this SECTION 1, on the date that such Registrable Securities are delivered to
the underwriters for sale in connection with a registration statement pursuant
to this SECTION 1, if such securities are being sold through underwriters, or,
if such securities are not being sold through underwriters, on the date that the
registration statement with respect to such securities becomes effective, (i) an
opinion, dated such date, of the counsel representing the Company for the
purposes of such registration, in form and substance as is customarily given to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of the Registrable
Securities, and (ii) a letter dated such date, from the independent certified
public accountants of the Company, in form and substance as is customarily given
by independent certified public accountants to underwriters in an underwritten
public offering, addressed to the underwriters, if any, and to the Holders
requesting registration of Registrable Securities.

               (l) Notify each seller of Registrable Securities under such
registration statement of (i) the effectiveness of such registration statement,
(ii) the filing of any post-effective amendments to such registration statement,
or (iii) the filing of a supplement to such registration statement.

          1.5 FURNISH INFORMATION.

               (a) It shall be a condition precedent to the obligations of the
Company to take any action pursuant to this SECTION 1 with respect to the
Registrable Securities of any selling Holder that such Holder shall furnish to
the Company such information regarding itself, the Registrable Securities held
by it, and the intended method of disposition of such securities as shall be
required to effect the registration of such Holder's Registrable Securities.

               (b) The Company shall have no obligation with respect to any
registration requested pursuant to SECTION 1.2 hereof if, as a result of the
application of SECTION 1.5(A), the number of shares of the Registrable
Securities to be included in the registration does not equal or exceed the
number of shares required to originally trigger the Company's obligation to
initiate such registration as specified in SECTION 1.2 hereof.

          1.6 EXPENSES OF REGISTRATION. All expenses (other than underwriting
discounts and commissions, stock transfer taxes and fees of counsel to the
stockholders in excess of $15,000) incurred in connection with any
registrations, filings or qualifications of Registrable Securities pursuant to
SECTIONS 1.2 or 1.3 including (without limitation) all federal or state
registration, filing and qualification fees, printers' and accounting fees and
fees and disbursements of counsel for the Company shall be borne by the Company.
The Company shall pay up to an aggregate of $15,000 of the selling stockholders'
legal fees in connection with one (1) registration. Notwithstanding the
foregoing, the Company shall not be required to pay for any expenses of any
registration proceeding begun pursuant to SECTION 1.2 if the registration
request is subsequently withdrawn at the request of the Holders of a majority of
the Registrable Securities to be registered, unless the withdrawal is based upon
a material adverse development concerning the Company and the Holders have
withdrawn the request with reasonable promptness following disclosure by the
Company of such material adverse change.

          1.7 UNDERWRITING REQUIREMENTS. In connection with any offering
pursuant to SECTION 1.3 involving an underwriting of shares of the Company's
capital stock by the Company, the Company shall not be required to include any
of the Holders' securities in such underwriting unless they accept the terms of
the underwriting as agreed upon between the Company and the underwriters
selected by it (or by other persons entitled to select the underwriters), and
then only in such quantity as the underwriters determine in their sole
discretion will not jeopardize the success of the offering by the Company. If
the total amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters determine in their sole
discretion is compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such
securities, including Registrable Securities, which the underwriters determine
in their sole discretion will not jeopardize the success of the offering (the
securities so included to be apportioned pro rata among the selling stockholders
according to the total amount of securities entitled to be included therein
owned by each selling stockholder, or in such other proportions as shall
mutually be agreed to by such selling stockholders). For purposes of the
preceding parenthetical concerning apportionment, for any selling stockholder
which is a holder of Registrable Securities and which is a limited liability
company, partnership or corporation, the members, partners, retired partners and
stockholders of such holder, or the estates and family members of any such
members, partners and retired partners and any trusts for the benefit of any of
the foregoing persons shall be deemed to be a single "selling stockholder," and
any pro-rata reduction with respect to such "selling stockholder" shall be based
upon the aggregate amount of shares carrying registration rights owned by all
entities and individuals included in such "selling stockholder," as defined in
this sentence.

          1.8 DELAY OF REGISTRATION. No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this SECTION 1.

          1.9 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under this SECTION 1:

               (a) To the maximum extent permitted by law, the Company will
indemnify and hold harmless each Holder, the partners, officers, and directors
of each Holder, any underwriter (as defined in the Act) for such Holder and each
person, if any, who controls such Holder or underwriter within the meaning of
the Act or the 1934 Act, against any losses, claims, damages or liabilities
(joint or several) to which they may become subject under the Act, the 1934 Act
or any state securities law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"VIOLATION"): (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by the
Company of the Act, the 1934 Act, or any rule or regulation promulgated under
the Act or the 1934 Act or any state securities law in connection with the
offering covered by such Registration Statement; and the Company will pay to
each such Holder, partner, officer, director, underwriter or controlling person,
as incurred, any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; PROVIDED, HOWEVER, that the indemnity agreement contained
in this SECTION 1.9(A) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability, or action if such settlement is effected without
the consent of the Company (which consent shall not be unreasonably withheld or
delayed), nor shall the Company be liable to any Holder, underwriter or
controlling person for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by any such Holder, partner, officer,
director, underwriter or controlling person.

               (b) To the maximum extent permitted by law, each selling Holder
will, if Registrable Securities held by such Holder are included in the
applicable registration statement, indemnify and hold harmless the Company, each
of its directors, each of its officers who has signed the registration
statement, each person, if any, who controls the Company within the meaning of
the Act, any underwriter, any other Holder selling securities in such
registration statement and any controlling person of any such underwriter or
other Holder, against any losses, claims, damages or liabilities (joint or
several) to which any of the foregoing persons may become subject under the Act

                                      -7-
<PAGE>

or the 1934 Act or any state securities law in connection with the offering
covered by such registration statement insofar as such losses, claims, damages
or liabilities (or actions in respect thereto) arise out of or are based upon
any Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder expressly for use in connection with such registration;
and each such Holder will pay any legal or other expenses reasonably incurred by
any person intended to be indemnified pursuant to this SECTION 1.9(B), in
connection with investigating or defending any such loss, claim, damage,
liability or action; PROVIDED, HOWEVER, that the indemnity agreement contained
in this SECTION 1.9(B) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Holder (which consent shall not be unreasonably withheld or
delayed); PROVIDED FURTHER, that in no event shall any indemnity under this
SECTION 1.9(B) exceed the net proceeds from the offering received by such
Holder, except in the case of willful misconduct or fraud by such Holder.

               (c) Promptly after receipt by an indemnified party under this
SECTION 1.9 of notice of the commencement of any action (including any
governmental action) as to which indemnity may be sought hereunder, such
indemnified party will, if a claim in respect thereof is to be made against any
indemnifying party under this SECTION 1.9, deliver to the indemnifying party a
written notice of the commencement thereof. The indemnifying party shall have
the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
the defense thereof with counsel mutually satisfactory to the parties; PROVIDED,
HOWEVER, that an indemnified party (together with all other indemnified parties
which may be represented without conflict by one counsel) shall have the right
to retain one separate counsel, with the reasonable fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this SECTION 1.9, but the omission to so deliver written
notice to the indemnifying party will not relieve the indemnifying party of any
liability that it may have to any indemnified party otherwise than under this
SECTION 1.9. No indemnifying party, in the defense of any such claim or
litigation, shall, except upon the consent of each indemnified party, consent to
entry of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a full and unconditional release from all liability in
respect to such claim or litigation.

               (d) The foregoing indemnity agreements of the Company and Holders
are subject to the condition that, insofar as they related to any Violation made
in a preliminary prospectus but eliminated or remedied in the amended prospectus
on file with the SEC at the time the registration statement in question becomes
effective or the amended prospectus filed with the SEC pursuant to SEC Rule
424(b) (the "FINAL PROSPECTUS"), such indemnity agreement shall not inure to the
benefit of any person if a copy of the Final Prospectus was furnished to the
indemnified party and was not furnished to the person asserting the loss,
liability, claim or damage at or prior to the time such action is required by

                                      -8-
<PAGE>

the Act. If the indemnification provided for in this SECTION 1.9 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 amount 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 in connection with the statements
or omissions that resulted in such loss, claim, damage or liability, as well as
any other relevant equitable considerations; PROVIDED, HOWEVER, that in no event
shall (i) any contribution by a Holder under this SECTION 1.9(D) exceed the net
proceeds from the offering received by such Holder, except in the case of
willful fraud by such Holder, and (ii) any person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) be entitled
to contribution from any person or entity who was not guilty of such fraudulent
misrepresentation. 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) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

               (f) The obligations of the Company and Holders under this SECTION
1.9 shall survive the completion of any offering of Registrable Securities in a
registration statement under this SECTION 1, and otherwise.

          1.10 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities, including a subsidiary, affiliate, partner, limited
partner, retired partner or stockholder of a Holder, provided in each case that
(i) the Company is, within a reasonable time after such transfer, furnished with
written notice of the name and address of such transferee or assignee and the
securities with respect to which such registration rights are being assigned;
(ii) such transferee or assignee agrees in writing to be bound by and subject to
the terms and conditions of this Agreement; and (iii) such assignment shall be
effective only if immediately following such transfer the further disposition of
such securities by the transferee or assignee is restricted under the Act.

          1.11 REPORTS UNDER THE 1934 ACT. The Company agrees to use
commercially reasonable efforts: (a) to make and keep public information
available, as those terms are understood and defined in the General Instructions
to Form S-3, or any successor or substitute form, and in Rule 144, (b) to file
with the SEC in a timely manner all reports and other documents required to be
filed by an issuer of securities registered under the Securities Act or the
Exchange Act, (c) as long as any Holder owns any Registrable Securities, to
furnish in writing upon such Holder's request a written statement by the Company
that it has complied with the reporting requirements of Rule 144 and of the Act
and the 1934 Act, and to furnish to such Holder a copy of the most recent annual
or quarterly report of the Company, and such other reports and documents so
filed by the Company with the SEC as may be reasonably requested.

<PAGE>

          1.12 DEFERRAL. Notwithstanding anything in this Agreement to the
contrary, if the Company shall furnish to the Holders a certificate signed by
the Chief Executive Officer of the Company stating that the Board of Directors
of the Company has made the good faith determination (a) that continued use by
the Holders of a registration statement for purposes of effecting offers or
sales of Registrable Securities pursuant thereto would require, under the Act,
premature disclosure in the registration statement (or the prospectus relating
thereto) of material, nonpublic information concerning the Company, its business
or prospects or any proposed material transaction involving the Company, (b)
that such premature disclosure would be materially adverse to the Company, its
business or prospects or any such proposed material transaction or would make
the successful consummation by the Company of any such material transaction
significantly less likely; and (c) that it is therefore essential to suspend the
use by the Holders of any such registration statement (and the prospectus
relating thereto) for purposes of effecting offers or sales of Registrable
Securities pursuant thereto, then the right of the Holders to use any such
registration statement (and the prospectus relating thereto) for purposes of
effecting offers or sales of Registrable Securities pursuant thereto shall be
suspended until further notice by the Company (the "SUSPENSION PERIOD"). During
the Suspension Period, none of the Holders shall offer or sell any Registrable
Securities pursuant to or in reliance upon any such registration statement (or
the prospectus relating thereto). In the event the Company exercises the
suspension rights set forth herein (the "SUSPENSION RIGHT"), such suspension
will continue for such period of time reasonably necessary for disclosure to
occur at a time that is not materially detrimental to the Company or until such
time as the registration statement does not include any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading in light of the
circumstances under which they were made, each as determined in good faith by
the Company. The Company agrees to notify the Holders promptly upon termination
of the Suspension Right. Notwithstanding the foregoing, under no circumstances
shall the Company be entitled to exercise the Suspension Right for a period of
more than thirty (30) days during any twelve (12) month period.

          1.13 LIMITATION OF LIABILITY. The Company shall not be liable to the
Holder for a failure to effect, or a delay in effecting, a registration
hereunder or a default in any other obligations under this Agreement arising out
of or relating to any failure to receive necessary consents from its independent
auditors or any internal review, investigation or similar activity by the
Company's Audit Committee.

          1.14 TERMINATION OF REGISTRATION RIGHTS. The rights granted under this
Section 1 shall terminate upon the fourth anniversary of the date of this
Agreement. In addition, a Holder's registration rights shall terminate if all
Registrable Securities held by and issuable to such Holder may be sold under
Rule 144 during any ninety (90) day period.

     2. MISCELLANEOUS.

          2.1 SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, the
terms and conditions of this Agreement shall inure to the benefit of and be
binding upon the respective successors and assigns of the parties (including
transferees of any shares of Registrable Securities). Nothing in this Agreement,
express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and assigns any rights, remedies,
obligations, or liabilities under or by reason of this Agreement.

under the laws of the State of Delaware as applied to agreements among Delaware
residents entered into and to be performed entirely within Delaware.

          2.3 SUBMISSION TO JURISDICTION; WAIVERS. Each of the parties hereto
irrevocably agrees that any legal action or proceeding with respect to this
Agreement or for the recognition and enforcement of any judgment in respect
hereof brought by the other party hereto or its successors or assigns will be
brought and determined in the Chancery or other courts of the State of Delaware,
and each of the parties hereby irrevocably submits with regard to any such
action or proceeding for itself and in respect to its property, generally and
unconditionally, to the exclusive jurisdiction of the aforesaid courts. Each of
the parties hereto hereby irrevocably waives, and agrees not to assert, by way
of motion, as a defense, counterclaim or otherwise, in any action or proceeding
with respect to this Agreement, (a) any claim that it is not personally subject
to the jurisdiction of the above-named courts for any reason other than the
failure to lawfully serve process, (b) that it or its property is exempt or
immune from jurisdiction of any such court or from any legal process commenced
in such courts (whether through service of notice, attachment prior to judgment,
attachment in aid of execution of judgment, execution of judgment or otherwise),
(c) to the fullest extent permitted by applicable law, that (i) the suit, action
or proceeding in any such court is brought in an inconvenient forum, (ii) the
venue of such suit, action, or proceeding is improper and (iii) this Agreement,
or the subject matter hereof, may not be enforced in or by such courts and (d)
any right to trial by jury.

          2.4 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

          2.5 TITLES AND SUBTITLES. The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

          2.6 NOTICES. All notices and other communications required or

not sent during normal business hours, then on the next business day, (c) three

requested, postage prepaid, or (d) one day after deposit with a nationally
recognized overnight courier, specifying next day delivery, with written
verification of receipt. All communications shall be sent to the address as set

          2.7 EXPENSES. If any action at law or in equity is necessary to
enforce or interpret the terms of this Agreement, the prevailing party shall be
entitled to reasonable attorneys' fees, costs and necessary disbursements in
addition to any other relief to which such party may be entitled.

          2.8 AMENDMENTS AND WAIVERS. Any term of this Agreement may be amended
and the observance of any term of this Agreement may be waived (either generally
or in a particular instance and either retroactively or prospectively), only
with the written consent of the Company and the Holders of sixty-six and
two-thirds percent (66 2/3%) of the Registrable Securities then outstanding. Any
amendment or waiver effected in accordance with this paragraph shall be binding
upon each Holder of any Registrable Securities then outstanding, each future
Holder of all such Registrable Securities, and the Company.

          2.9 SEVERABILITY. If one or more provisions of this Agreement are held
to be unenforceable under applicable law, such provision shall be excluded from
this Agreement and the balance of the Agreement shall be interpreted as if such
provision were so excluded and shall be enforceable in accordance with its
terms.

          2.10 AGGREGATION OF STOCK. All shares of Registrable Securities held
or acquired by affiliated entities or persons shall be aggregated together for
the purpose of determining the availability of any rights under this Agreement.

such additional purchaser, each such additional purchaser shall thereafter be
deemed an "Investor" for all purposes hereunder and SCHEDULE A shall be updated
