                       FUSION MEDICAL TECHNOLOGIES, INC.

                     STOCK AND WARRANT PURCHASE AGREEMENT

     THIS STOCK AND WARRANT PURCHASE AGREEMENT is made as of the 2/nd/ day of
April 2001, by and between Fusion Medical Technologies, Inc. (the "Company"), a
corporation organized under the laws of the State of Delaware, with its
principal offices at 34175 Ardenwood Boulevard, Fremont, California 94555, and
the purchasers whose names and addresses are set forth on the signature page
hereof (individually a "Purchaser" and collectively the "Purchasers").

     IN CONSIDERATION of the mutual covenants contained in this Agreement, the
Company and the Purchaser agree as follows:

     1.   Authorization of Sale of the Securities. Subject to the terms and
          ---------------------------------------
conditions of this Agreement, the Company has authorized the sale of up to
3,500,000 shares of the Company's Common Stock, par value $0.001 per share (the

900,000 shares of Common Stock (the "Warrant Shares") on the terms set forth
herein (each a "Warrant" and collectively the "Warrants"). The Shares, the
Warrants and the Warrant Shares are herein collectively referred to as the
"Securities".

     2.   Agreement to Sell and Purchase the Securities.
          ---------------------------------------------

          (a)  Execution Date. The "Execution Date" shall be the date each
               --------------
Purchaser signs this Agreement with the Company, whereupon the Company shall
agree to sell to the Purchaser, and the Purchaser shall agree to buy from the
Company, upon the terms and conditions hereinafter set forth, the number of
Shares and Warrants set forth opposite such Purchaser's name on Exhibit A
hereto.

          (b)  Calculation of the Purchase Price. The Shares will be sold to

price is the current market price of the Company's Common Stock calculated as
follows: the average of the daily closing stock prices for the Company's Common
Stock (ticker symbol "FSON") traded on the Nasdaq National Market for each of
the ten (10) trading days preceding the Execution Date of the Agreement (the
"Purchase Price").

          (c)  Calculation of the Warrants. The shares underlying each Warrant
               ---------------------------
as reflected on Exhibit A is calculated as follows: 25% of the aggregate
principal amount paid by the Purchaser divided by the Purchase Price. The
Warrant shall have an exercise price of $3.66, which is equal to 125% of the
Purchase Price. The Warrant shall be exercisable, in whole or in part until
April 2, 2006. The Warrant shall be in the form attached as Exhibit C hereto. No

Company as follows:

               (a)  Authority. The Purchaser has full power and authority to
                    ---------
execute and deliver, and to consummate the transactions contemplated by this
Agreement. All corporate action on the part of the Purchaser, its officers,

consummation of the transactions contemplated by, this Agreement. This
Agreement, upon execution and delivery by the Purchaser and assuming the due and
proper execution and delivery by the Company, constitutes a legal, valid and
binding obligation of the Purchaser, enforceable in accordance with its terms,
except as may be limited by (i) applicable bankruptcy, insolvency,

Company, which by the Purchaser's execution of this Agreement, the Purchaser
hereby confirms, that the Securities to be acquired by the Purchaser shall be
acquired for investment for the Purchaser's own account, not as a nominee or
agent, and not with a view to the distribution of any part thereof, and that the

<PAGE>

               (d)  Investment Experience. The Purchaser acknowledges that it is
                    ---------------------
able to fend for itself, can bear the economic risk of its investment, and has
such knowledge and experience in financial or business matters that it is
capable of evaluating the merits and risks of the investment in the Securities.
The Purchaser has not been organized for the purpose of acquiring the
Securities.

               (e)  Accredited Investor. The Purchaser is an "accredited

                    ---------------------
Securities it is purchasing are characterized as "restricted securities" under
the federal securities laws inasmuch as they are being acquired from the Company
in a transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Securities Act only in certain limited circumstances. In this connection,
the Purchaser represents that it is familiar with SEC Rule 144 or Rule 144A, as
presently in effect, and understands the resale limitations imposed thereby and
by the Securities Act.

     6.   Survival of Representations, Warranties and Agreements.
          ------------------------------------------------------
Notwithstanding any investigation made by any party to this Agreement, all
covenants, agreements, representations and warranties made by the Company and
the Purchaser herein shall survive until the three year anniversary of the
Closing.

     7.   Covenants of the Company.
          ------------------------

               (a)  Future Sales of Common Stock. In the event the Company
                    ----------------------------
shall, within ninety (90) days following the Closing Date, sell any shares of
the Company's Common Stock at, or any instruments (excluding the Company's 1993
Stock Option Plan, the 1996 Director Option Plan and the Employee Stock Purchase
Plan) that can be converted into or otherwise exchanged for the Company's Common
Stock (the "Subsequent Sale") exercisable at, a price per share (the "Subsequent
Purchase Price") of less than the Purchase Price, (1) the purchase price per
Share hereunder shall be adjusted to an amount equal to the Subsequent Purchase
Price, such that the Company shall, within ten (10) business days of the
Subsequent Sale, pay to each Purchaser an amount equal to the number of Shares
times the difference between the Purchase Price and the Subsequent Purchase
Price; and (2) the Company shall, within ten (10) business days of the
Subsequent Sale, deliver new Warrants to each Purchaser in exchange for the
previously issued Warrants that shall have an exercise price per share equal to
125% of the Subsequent Purchase Price.

               (b)  Listing of Shares. The Company agrees to promptly secure the
                    -----------------
listing of the Shares and Warrant Shares upon each national securities exchange
or automated quotation system upon which shares of Common Stock are then listed
for so long as any Purchaser owns any of the Shares or Warrant Shares. The
Company has taken no action designed to delist, or which is likely to have the
effect of delisting, the Common Stock from any of the national securities
exchange or automated quotation system upon which the shares of Common Stock are
then listed.

               (c)  Bylaw Amendment. The Company shall, within thirty (30) days
                    ---------------
of the Closing Date, adopt such amendments to, with respect to (i) and (ii)
below, the Company's stock option plans and Bylaws, and, with respect to (iii)
below, the Company's Bylaws (together, the "Stock Option Plan and Bylaw
Amendments") to provide that, unless approved by the holders of a majority of
the shares present and entitled to vote at a duly convened meeting of
shareholders, the company shall not (i) grant any stock options with an exercise
price that is less than 100% of the fair market value of the underlying stock on
the date of grant; (ii) reduce the exercise price of any stock option granted
under any existing or future stock option plan; or (iii)

                                      -8-
<PAGE>

sell or issue any security of the Company convertible, exercisable or
exchangeable into shares of Common Stock, having a conversion, exercise or
exchange price per share which is subject to downward adjustment based on the
market price of the Common Stock at the time of conversion, exercise or exchange
of such security into Common Stock (other than pursuant to customary anti-
dilution provisions). The Stock Option Plan and Bylaw amendments may not be
further amended or repealed without the affirmative vote of the holders of a
majority of the shares present and entitled to vote at a duly convened meeting
of shareholders. Upon the adoption of the Stock Option Plan and Bylaw
Amendments, the Company shall promptly furnish a copy of such amendments to the
Purchaser. The Company agrees that, prior to the adoption of the Stock Option
Plan and Bylaw Amendments by all necessary corporate action of the Company as
described above, the Company shall not conduct any of the actions specified in
(i), (ii) or (iii) above of this Section 7.3.

     8.   Covenants of the Purchaser.
          --------------------------

               (a)  Limitations on Disposition. Without in any way limiting any
                    --------------------------
other provision set forth herein, the Purchaser further agrees not to make any
disposition of all or any portion of the Securities unless and until:

                    (i)   There is then in effect a registration statement under
the Securities Act covering such proposed disposition and such disposition is
made in accordance with such Registration Statement;

                    (ii)  Such disposition shall be permitted under the
provisions of Rule 144; or

                    (iii) There is a valid exemption from registration under the
Securities Act and other applicable securities laws and, if requested by the
Company, the Purchaser shall have furnished the Company with an opinion of
counsel, reasonably satisfactory to the Company, that such disposition shall not
require registration.

          (b)  Prospectus Delivery. The Purchaser hereby covenants with the
               -------------------
Company not to make any sale of any Securities under a registration statement
without effectively causing the prospectus delivery requirement under the
Securities Act to be satisfied. The Purchaser acknowledges and agrees that such
Securities are not transferable on the books of the Company pursuant to a resale
under a registration statement unless the certificate submitted to the transfer
agent evidencing such Securities is accompanied by a separate officer's
certificate, (i) which may be in the form of Appendix II hereto, (ii) executed
by an officer of, or other authorized person designated by, the Purchaser, and
(iii) to the effect that (a) such Securities have been sold in accordance with
the registration statement and (b) the requirement of delivering a current
prospectus has been satisfied. The Purchaser acknowledges that there may
occasionally be times when the Company must suspend the use of the prospectus
forming a part of the registration statement until such time as an amendment to
the registration statement has been filed by the Company and declared effective
by the Securities and Exchange Commission (the "Commission"), or until such time
as the Company has filed an appropriate report with the Commission pursuant to
the Exchange Act. The Purchaser hereby covenants that it shall not sell any
Securities pursuant to such prospectus during the period commencing at the time
at which the Company gives the Purchaser prompt written notice of the suspension
of the use of such prospectus and ending at the time the Company gives the
Purchaser written notice that the Purchaser may thereafter effect sales pursuant
to such prospectus and any amendments thereto. In no event shall the Company
suspend the use of the prospectus for periods exceeding 30 days during any 12-
month period and any such suspension must be separated by a period of 30 days.

                                      -9-
<PAGE>

     9.   Legends. Each certificate or instrument representing Securities
          -------
delivered at the Closing shall bear legends in substantially the following
forms:

                    (1)  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE `SECURITIES ACT') AND
ARE `RESTRICTED SECURITIES' AS DEFINED IN RULE 144 PROMULGATED UNDER THE
SECURITIES ACT. THE SECURITIES MAY NOT BE SOLD OR OFFERED FOR SALE OR OTHERWISE
DISTRIBUTED EXCEPT (I) IN CONJUNCTION WITH AN EFFECTIVE REGISTRATION STATEMENT
FOR THE SECURITIES UNDER THE SECURITIES ACT, OR (II) IN COMPLIANCE WITH RULE
144, OR (III) PURSUANT TO AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF
THESE SECURITIES THAT SUCH REGISTRATION OR COMPLIANCE IS NOT REQUIRED AS TO SUCH
SALE, OFFER OR DISTRIBUTION."

                    (2)  Any other legends required by California law or other
applicable blue sky or state securities laws.

The Company need not register a transfer of any Securities, and may also
instruct its transfer agent not to register a transfer of any Securities, unless
the conditions specified in the foregoing legends are satisfied to the extent
applicable.

     10.  Registration of the Securities; Compliance with the Securities Act.
          ------------------------------------------------------------------

               (a)  Registration Procedures and Expenses. The Company shall:
                    ------------------------------------

                         (i)   within 30 business days after the Closing Date,
prepare and file with the Commission a registration statement on Form S-3 (the
"Registration Statement") relating to the sale of the Securities by the
Purchaser on the Nasdaq National Market or the facilities of any national
exchange on which the Common Stock is then traded or in privately-negotiated
transactions;

                         (ii)  shall respond to all Commission comments within
ten (10) calendar days of receipt of said comments and will use its best
efforts, subject to receipt of necessary information from the Purchasers, to
cause the Commission to notify the Company of the Commission's willingness to
grant acceleration of the effective date of the Registration Statement within 90
days after the Registration Statement is initially filed by the Company;

                         (iii) promptly notify the Purchaser upon the
Registration Statement being declared effective by the Commission;

                         (iv)  provide to the Purchaser any information
necessary to permit sale of the Securities under Rule 144 or Rule 144A of the
Securities Act.

                         (v)   prepare and file with the Commission such
amendments and supplements to the Registration Statement and the prospectus used
in connection therewith as may be necessary to keep the Registration Statement
effective until the date on which the Purchaser's Securities may be resold in
any three-month period by the Purchaser without registration and without any
restrictions or volume limitations by reason of Rule 144(k) under the Securities
Act or any other rule of similar effect;

                                      -10-
<PAGE>

STOCK AND WARRANT PURCHASE AGREEMENT

                 (vi)    promptly furnish to the Purchaser with respect to the
Securities registered under the Registration Statement (and to each underwriter,
if any, of such Securities) such number of copies of prospectuses and such other
documents as the Purchaser may reasonably request, in order to facilitate the
public sale or other disposition of all or any of the Purchaser's Securities by
the Purchaser; provided, however, that the obligation of the Company to deliver
copies of prospectuses to the Purchaser shall be subject to the receipt by the
Company of reasonable assurances from the Purchaser that the Purchaser shall
comply with the applicable provisions of the Securities Act and of such other
securities or blue sky laws as may be applicable in connection with any use of
such prospectuses;

                 (vii)   file documents required of the Company for normal blue
sky clearance in all states requiring blue sky clearance; provided, however,
that the Company shall not be required to qualify to do business or consent to
service of process in any jurisdiction in which it is not now so qualified or
has not so consented unless failing to so qualify or consent has a Material
Adverse Effect on the Company; and

                 (viii)  bear all expenses in connection with the procedures in
paragraphs (a) through (g) of this Section 10.1 and the registration of the
Securities pursuant to the Registration Statement, other than underwriting
discounts, brokerage fees and commissions incurred by the Purchaser, if any.

          (b) Delay in Effectiveness of Registration Statement. In the event
              ------------------------------------------------
that the Registration Statement is not declared effective on or before the 90th
day following the Closing Date (the "Penalty Date"), the Company shall pay to
each Purchaser liquidated damages in an amount equal to 0.25% of the total
purchase price of the Securities purchased by such Purchaser pursuant to this
Agreement for each week after the Penalty Date that the Registration Statement
is not declared effective.

          (c) Transfer of Securities After Registration. The Purchaser agrees
              -----------------------------------------
that it shall not effect any disposition of any Securities or its right to
purchase any Securities that would constitute a sale within the meaning of the
Securities Act, except as contemplated in the Registration Statement referred to
in Section 10.1 or as otherwise permitted by law, and that it shall promptly
notify the Company of any changes in the information set forth in the
Registration Statement regarding the Purchaser or its plan of distribution.

          (d) Indemnification. In the event any securities are included in a
              ---------------
registration statement under this Section 10:

                 (i)     To the extent permitted by law, the Company shall
indemnify and hold harmless the Purchaser and each person, if any, who controls
the Purchaser within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the Securities Act or the Exchange Act or other
federal or state 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) in connection with the sale or purchase of the Securities, any violation
or alleged violation by the Company of the Securities Act, the Exchange Act, any
state securities law or any rule or regulation promulgated under the Securities
Act, or the Exchange Act or any state securities law; and the Company shall pay
to the Purchaser or controlling person, as incurred, any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss,

                                      -11-
<PAGE>

STOCK AND WARRANT PURCHASE AGREEMENT

claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this subsection 10.4(a) shall not apply to amounts paid
in settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by the Purchaser or controlling person.

                 (ii)    To the extent permitted by law, the Purchaser shall
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Securities Act, its attorneys,
its underwriters, and any controlling person of any such underwriter, 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 the
Exchange Act or other federal or state law, 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 the Purchaser expressly for use in connection with such
registration; and the Purchaser shall pay, as incurred, any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant
to this subsection 10.4(b), in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
indemnity agreement contained in this subsection 10.4(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 Purchaser, which
consent shall not be unreasonably withheld; provided, that, in no event shall
any indemnity under this subsection 10.4(b) exceed the gross proceeds from the
offering received by the Purchaser.

                 (iii)   Promptly after receipt by an indemnified party under
this Section 10.4 of notice of the commencement of any action (including any
governmental action), such indemnified party shall, if a claim in respect
thereof is to be made against any indemnifying party under this Section 10.4,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
10.4, but the omission so to deliver written notice to the indemnifying party
shall not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10.4.

                 (iv)    If the indemnification provided for in this Section
10.4 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the

                                      -12-
<PAGE>

STOCK AND WARRANT PURCHASE AGREEMENT

indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations; provided that in no event shall any contribution by the
                --------
Purchaser under this subsection 10.3(d) exceed the amount of the gross proceeds
received by the Purchaser from the offering. 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.

                 (v)     The obligations of the Company and the Purchaser under
this Section 10.4 shall survive the completion of any offering of securities in
a registration statement under this Section 10.4 or otherwise.

          (e) Termination of Registration Obligations. The obligations of the
              ---------------------------------------
Company set forth in Section 10.1 shall cease and terminate as to the
Purchaser's Securities on the date on which (i) all such Securities are eligible
for sale during any three-month period without restriction including volume
limitations, under Rule 144, (ii) all such Securities have been effectively
registered under the Securities Act and sold or otherwise disposed of by the
Purchaser in accordance with the intended method of disposition set forth in the
Registration Statement or (iii) the Company receives an opinion of counsel
satisfactory in form and substance to the Company to the effect that such
conditions are not necessary in order for a transfer of such Securities to
comply with the Securities Act.

          (f) Information Available. So long as the Registration Statement is
              ---------------------
effective covering the resale of Securities owned by the Purchaser, the Company
shall furnish to the Purchaser:

                 (i)     as soon as practicable after the Company has made such
information available to the public through submission to the SEC (but in the
case of the Company's Annual Report to Stockholders, within 120 days after the
end of each fiscal year of the Company), one copy of (i) its Annual Report to
Stockholders, (ii) if not included in substance in the Annual Report to
Stockholders, its Annual Report on Form 10-K, (iii) its Quarterly Reports on
Form 10-Q, (iv) its Current Reports on Form 8-K, and (v) a full copy of the
particular Registration Statement covering the Securities (the foregoing, in
each case, excluding exhibits); and

                 (ii)    upon the written request of the Purchaser, a reasonable
number of copies of the prospectuses to supply to any other party requiring such
prospectuses in connection with the Purchaser's prospectus delivery requirements
under the Securities Act; and

                 (iii)   the Company, upon the reasonable request of the
Purchaser, shall meet with the Purchaser or a representative thereof at the
Company's headquarters to discuss information relevant for disclosure in the
Registration Statement covering the Securities, subject to appropriate
confidentiality limitations as the Company may require.

     11. Rule 144 Information. For two years after the date of this Agreement,
         --------------------
the Company shall file all reports required to be filed by it under the
Securities Act, and the Exchange Act and shall take such further action to the
extent required to enable the Purchasers to sell the Securities pursuant to Rule
144 under the Securities Act (as such rule may be amended from time to time).

STOCK AND WARRANT PURCHASE AGREEMENT

                                   EXHIBIT D

                             SCHEDULE OF EXCEPTIONS

     This Schedule of Exceptions, is made pursuant to Section 4 of the Fusion
Medical Technologies, Inc.'s (the "Company") Stock and Warrant Purchase
Agreement (the "Agreement").  The section numbers in this Schedule of Exceptions
correspond to the section numbers in the Agreement; however, any information
disclosed herein under any section number shall be deemed to be disclosed and
incorporated into any other paragraph number under the Agreement where such
disclosure would be appropriate.  Any terms defined in the Agreement shall have
the same meaning when used in this Schedule of Exceptions as when used in the
Agreement unless the context otherwise requires.

     Section 4.2   Capitalization.  The Company has a Preferred Shares Rights
                   --------------
Agreement dated as of October 10, 1997, as amended on March 30, 1999 (the
"Rights Agreement") which provides registered holders of the Company's Common
Stock the right to purchase 1/1000th share of the Company's Series A
Participating Preferred Stock for each share of Common Stock then held (the
"Rights").  The Rights separate from the Common Shares and Rights Certificates
are issued and the Rights become exercisable upon 10 days (or such later date as
may be determined by a majority of the Board of Directors, excluding directors
affiliated with the Acquiring Person), following a public announcement that a
person or a group of affiliated or associated persons has acquired, or obtained
the right to acquire, beneficial ownership of 15% or more of the outstanding
Common Shares (the "Distribution Date").  On April 2, 2001, the representations
and warranties made to each Purchaser by the Company failed to disclose the
existence of the Rights Agreement and the need to amend the Rights Agreement in
order to avoid Alloy Ventures ("Alloy") and the State of Wisconsin Investment
Board ("SWIB") falling within the definition of an "Acquiring Person"
thereunder.  The Board of Directors has approved an amendment to the Rights
Agreement. The Company will prepare and file an amendment to the Rights
Agreement on or before April 12, 2001 to increase from 15% to 20% the
designation of "Acquiring Person" for Alloy and SWIB.

     Section 4.4   Valid Issuance of the Securities.  The Company has an
                   --------------------------------
outstanding warrant (the "Warrant") currently exercisable into 4,500 Common
Stock shares of the Company.  After completion of the Agreement, the Warrant
will be exercisable into 6,000 Common Stock shares due to the anti-dilution
provision contained in the Warrant.

     Section 4.10  Litigation.  On December 19, 2000, Cohesion Technologies,
                   ----------
Inc. filed a patent infringement action against the Company in United States
District Court, Northern District of California (San Jose) claiming that the
Company infringed on Cohesion Technologies' "Collagen-Polymer Matrices With
Differential Biodegradability" patent (Patent #6,110,484). Cohesion Technologies
is seeking unspecified damages and permanent injunctive relief. The Company
believes that Cohesion Technologies' claim is without merit.
