	8.	 	Amendment to Section 3.2 (Relating to Periodic Commitment Fee).

     Section 3.2 of the Existing Agreement is hereby amended to read as follows:

year (each a “Periodic Fee Date”), a periodic commitment fee (the “Periodic Commitment
Fee”). The Periodic Commitment Fee shall accrue from January 1, 2011.

     (b) The Periodic Commitment Fee is intended to fully compensate Purchaser for
the support provided by the ongoing Commitment following December 31, 2010. The
amount of the Periodic Commitment Fee shall be set not later than December 31, 2010
with respect to the ensuing five-year period, shall be reset every five years
thereafter and
shall be determined with reference to the market value of the Commitment as then in
effect. The amount of the Periodic Commitment Fee shall be mutually agreed by
Purchaser and Seller, subject to their reasonable discretion and in consultation with
the
Chairman of the Federal Reserve; provided, that Purchaser may waive the
Periodic
Commitment Fee for up to one year at a time, in its sole discretion, based on adverse
conditions in the United States mortgage market.

     (c) At the election of Seller, the Periodic Commitment Fee may be paid in cash or
by adding the amount thereof ratably to the liquidation preference of each outstanding
share of Senior Preferred Stock so that the aggregate liquidation preference of all
such
outstanding shares of Senior Preferred Stock is increased by an amount equal to the
Periodic Commitment Fee. Seller shall deliver notice of such election not later than
three
(3) Business Days prior to each Periodic Fee Date. If the Periodic Commitment Fee is
not
paid in cash by 12:00 pm (New York time) on the applicable Periodic Fee Date
(irrespective of Seller’s election pursuant to this subsection), Seller shall be deemed
to
have elected to pay the Periodic Commitment Fee by adding the amount thereof to the
liquidation preference of the Senior Preferred Stock, and the aggregate liquidation
preference of the outstanding shares of Senior Preferred Stock shall thereupon be
automatically increased, in the manner contemplated by the first sentence of this
section,
by an aggregate amount equal to the Periodic Commitment Fee then due.

	9.	 	Amendment to Section 5.7 (Relating to Owned Mortgage Assets).

     Section 5.7 of the Existing Agreement is hereby amended to read as follows:

     5.7. Mortgage Assets. Seller shall not own, as of any applicable date, Mortgage
Assets in excess of (i) on December 31, 2009, $900 billion, or (ii) on December 31 of
each year thereafter, 90.0% of the aggregate amount of Mortgage Assets that Seller was
permitted to own as of December 31 of the immediately

- 4 - 

 

	 	 	preceding calendar year; provided, that in no event shall Seller be
required under this Section 5.7 to own less than $250 billion in Mortgage Assets.
	 
	10.	 	Existing Agreement to Continue, as Amended.

        Except as expressly modified by this Second Amendment, the Existing Agreement shall
continue in full force and effect.

	11.	 	Effective Date.

        This Second Amendment shall not become effective until it has been executed by both of
Purchaser and Seller. When this Second Amendment has been so executed, it shall become effective as
of the date first above written.

Exhibit 10.1

SECURITIES PURCHASE AGREEMENT

     This Securities Purchase Agreement, dated on and as of December 24, 2009 (this
“Agreement”), is made between Vermillion, Inc., a Delaware corporation and debtor and
debtor-in-possession under Chapter 11 of the United States Bankruptcy Code (the “Company”),
the undersigned purchaser(s) (each a “Purchaser” and collectively, the
“Purchasers”) and each assignee of a Purchaser who becomes a party hereto.

     WHEREAS, the Company is a debtor and debtor-in-possession in Case No. 09-11091 (the
“Case”) pending in the United States Bankruptcy Court for the District of Delaware (the
“Bankruptcy Court”) (captioned In re: Vermillion, Inc.) under Chapter 11 of the
United States Bankruptcy Code (11 U.S.C. §101, et seq.)(the “Bankruptcy
Code”). The Company will be reorganized pursuant to a plan of reorganization (the “Plan of
Reorganization”), subject to entry of a final order confirming the Plan of Reorganization by
the Bankruptcy Court (the “Confirmation Order”).

     WHEREAS, subject to the terms and conditions set forth in this Agreement and pursuant to
Section 4(2) of the Securities Act of 1933, as amended (the “Securities Act”) and Rule 506
of Regulation D promulgated thereunder, the Company desires to offer, issue and sell to the
Purchasers (the “Offering”), and the Purchasers, severally and not jointly, desire to
purchase from the Company, shares (the “Shares”) of the Company’s common stock, par value
$0.001 per share (the “Common Stock”). The Shares are sometimes referred to herein as the
“Securities”.

     WHEREAS, the net proceeds of the Offering are intended to be used by the Company to finance in
part the distributions to be made under the Plan of Reorganization, to pay the fees and expenses
associated therewith, to repay in full the Company’s obligations under its debtor-in-possession
financing agreement with Quest Diagnostics Incorporated and for working capital and other general
corporate purposes of the Company and its subsidiaries.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements contained in this
Agreement, and for other good and valuable consideration the receipt and adequacy of which is
hereby acknowledged, the Company and each of the Purchasers agree as follows:

A. Subscription

     (1) Subject to the conditions to closing set forth herein, each Purchaser hereby irrevocably
subscribes for and agrees to purchase Securities for the aggregate purchase price set forth on the
signature page of such Purchaser hereto (the “Subscription Amount”). The Securities to be
issued to each Purchaser hereunder shall consist of Shares in an amount equal to the quotient of
(x) the Subscription Amount, divided by (y) the Share Purchase Price, rounded down to the nearest
whole number.

     (2) For the purposes of this Agreement, the purchase price for each Share shall be $18.4932
(the “Share Purchase Price”).

 

 

     (3) The Company shall use its reasonable best efforts to hold the closing of the Offering (the
“Closing”, and the date of the Closing, the “Closing Date”) as soon as practicable
after entry of the Confirmation Order by the Bankruptcy Court approving the Plan of Reorganization.
Prior to the Closing, each Purchaser shall deliver the applicable Subscription Amount, by wire
transfer to an escrow account in accordance with the wire transfer instructions set forth on
Schedule A, and such amount shall be held in the manner described in Paragraph (4) below.
There is no minimum Subscription Amount required for the Closing.

     (4) All payments for Securities made by the Purchasers will be deposited as soon as
practicable but by no later than 5:00 p.m. (New York time) on the date of this Agreement, in a
non-interest bearing escrow account. With respect to each Purchaser, payments for Securities made
by such Purchaser will be returned promptly, prior to an applicable Closing, without interest or
deduction, if, or to the extent, (i) such Purchaser’s subscription is rejected by the Company; (ii)
the Offering is terminated for any reason; or (iii) upon request by such Purchaser, if the Closing
does not occur within fifteen (15) days after the date of the Confirmation Order; provided,
however, that the foregoing clause (iii) shall not relieve any Purchaser of any liability in the
event the Closing does not occur within such fifteen (15) day period due to the failure of a
Purchaser to deliver such Purchaser’s applicable Subscription Amount.

     (5) Upon receipt by the Company of the requisite payment for all Securities to be purchased by
the Purchasers whose subscriptions are accepted, the Company shall, at the Closing: (i) issue to
each Purchaser stock certificates representing the shares of Common Stock purchased at such Closing
under this Agreement; (ii) deliver to the Purchasers a certificate stating that the representations
and warranties made by the Company in Section C of this Agreement are true and correct in all
material respects on the date of such Closing relating to the Securities subscribed for pursuant to
this Agreement as though made on and as of such Closing Date (provided, however, that
representations and warranties that speak as of a specific date shall continue to be true and
correct as of the Closing with respect to such date); (iii) cause to be delivered to the Purchasers
an opinion of Paul, Hastings, Janofsky & Walker LLP substantially in the form of Exhibit A
hereto; and (iv) cause to be delivered to the Purchasers as of a date within five (5) days of the
Closing Date evidence of the good standing and corporate existence of the Company issued by the
Delaware Secretary of State. Notwithstanding anything to the contrary herein, the Company and
Purchasers agree that no funds may be released to the Company from the escrow account until entry
of the Confirmation Order by the Bankruptcy Court approving the Plan of Reorganization, all of the
items required to be delivered by the Company pursuant to clauses (i), (ii), and (iii) of this
Paragraph (5) have been delivered in accordance with this Paragraph (5) and all other conditions to
Closing set forth in this Agreement have been satisfied or waived. Upon satisfaction or waiver of
all conditions to Closing set forth in this Agreement, funds may be released from the escrow
account upon the written instructions of the Company.

     (6) Each Purchaser acknowledges and agrees, solely with respect to itself, that (i) the
purchase of Shares by such Purchaser pursuant to the Offering is subject to all the terms and
conditions set forth in this Agreement; and (ii) this Agreement shall be binding upon such
Purchaser upon the execution and delivery to the Company of such Purchaser’s signed counterpart
signature page to this Agreement unless and until the Company shall promptly reject the
subscription being made hereby by such Purchaser.

B. Representations and Warranties of the Purchaser

     Each Purchaser, severally and not jointly, hereby represents and warrants only as to itself to
the Company, and agrees with the Company as follows:

     (1) Such Purchaser understands and acknowledges and is fully aware that (i) the Company
is a debtor and debtor-in-possession under Chapter 11 of the Bankruptcy Code in Case No. 09-11091
pending in the United States Bankruptcy Court for the District of Delaware, (ii) the Company is
delinquent in its filings with the Securities and Exchange Commission (the “SEC”),
including as a result of its failure to file any quarterly or annual periodic report on Form 10-Q
or Form 10-K for any quarterly or annual fiscal period ended after September 30, 2008; (iii) the
Securities are currently quoted on the “pink sheets”; and (iv) the Securities are not presently
quoted on the Nasdaq Capital Market nor listed for trading on any national securities exchange,
and, notwithstanding the circumstances described in the preceding clauses (i)(ii)(iii) and (iv)
(and without limiting any of the other representations and warranties or agreements of Purchaser
herein), such Purchaser has made its own investment decision to subscribe for and purchase
Securities issued in the Offering.

     (2) Such Purchaser has carefully read this Agreement and the Escrow Agreement attached
hereto as Exhibit B (collectively the “Offering Documents”), and is familiar with
and understands the terms of the Offering. Such Purchaser has also carefully read and considered
the Company’s Amended Disclosure Statement for Debtor’s First Amended Plan of Reorganization under
Chapter 11 of the Bankruptcy Code dated December 8, 2009 (the “Disclosure Statement”).
Such Purchaser has relied only on the information contained in the Offering Documents, the
Disclosure Statement and the Company’s SEC filings through the Closing Date (the “SEC
Filings”), and has not relied on any representation made by any other person, other than as set
forth in Paragraphs B.(3)-(4) below. Such Purchaser fully understands all of the risks related to
the purchase of the Securities. Such Purchaser has carefully considered and has discussed with
such Purchaser’s professional legal, tax, accounting and financial advisors, to the extent such
Purchaser has deemed necessary, the suitability of an investment in the Securities for such
Purchaser’s particular tax and financial situation and has determined that the Securities being
subscribed for by such Purchaser are a suitable investment for such Purchaser. Such Purchaser
recognizes that an investment in the Securities involves substantial risks, including the possible
loss of the entire amount of such investment. Such Purchaser further recognizes that the Company
has broad discretion concerning the use and application of the proceeds from the Offering.

     (3) Such Purchaser acknowledges that (i) such Purchaser has had the opportunity to request
copies of any documents, records, and books pertaining to this investment and (ii) any such
documents, records and books that such Purchaser requested have been made available for inspection
by such Purchaser, such Purchaser’s attorney, accountant or advisor(s).

     (4) Such Purchaser and such Purchaser’s advisor(s) have had a reasonable opportunity to
ask questions of and receive answers from representatives of the Company or persons acting on
behalf of the Company concerning the Offering and all such questions have been answered to the full
satisfaction of such Purchaser. Such Purchaser understands that it is not relying on any

3

 

representation of any kind made by the Company regarding the Company, the Securities or any other
matter other than as set forth herein.

     (5) Such Purchaser is not subscribing for Securities as a result of or subsequent to any
advertisement, article, notice or other communication published in any newspaper, magazine or
similar media or broadcast over television or radio or presented at any seminar, meeting or
conference whose attendees have been invited by any general solicitation or general advertising.

     (6) If such Purchaser is a natural person, such Purchaser has reached the age of majority
in the state in which such Purchaser resides. Such Purchaser has adequate means of providing for
such Purchaser’s current financial needs and contingencies, is able to bear the substantial
economic risks of an investment in the Securities for an indefinite period of time, has no need for
liquidity in such investment and can afford a complete loss of such investment.

     (7) Such Purchaser has sufficient knowledge and experience in financial, tax and business
matters to enable such Purchaser to utilize the information made available to such Purchaser in
connection with the Offering, to evaluate the merits and risks of an investment in the Securities
and to make an informed investment decision with respect to an investment in the Securities on the
terms described in the Offering Documents.

     (8) Such Purchaser will not sell or otherwise transfer the Securities without
registration under the Securities Act and applicable state securities laws or an applicable
exemption therefrom. Such Purchaser acknowledges that neither the offer nor sale of the Securities
has been registered under the Securities Act or under the securities laws of any state. Such
Purchaser represents and warrants that such Purchaser is acquiring the Securities for such
Purchaser’s own account and not with a current view toward resale or distribution within the
meaning of the Securities Act. Such Purchaser has not offered or sold the Securities being
acquired nor does such Purchaser have any present intention of selling, distributing or otherwise
disposing of such Securities either currently or after the passage of a fixed or determinable
period of time or upon the occurrence or non-occurrence of any predetermined event or circumstances
in violation of the Securities Act. Such Purchaser is aware that (i) the Securities are not
currently eligible for sale in reliance upon Rule 144 promulgated under the Securities Act and (ii)
the Company has no obligation to register the Securities subscribed for hereunder, except as
provided in Section E hereof. By making these representations herein, such Purchaser is not making
any representation or agreement to hold the Securities for any minimum or other specific term and
reserves the right to dispose of the Securities at any time in accordance with or pursuant to a
registration statement or an available exemption to the registration requirements of the Securities
Act.

     (9) Such Purchaser acknowledges that the certificates representing the Shares shall be
stamped or otherwise imprinted with a legend substantially in the following form:

The securities represented hereby have not been registered under the
Securities Act of 1933, as amended, or any state securities laws and
neither the securities nor any interest therein may be offered,
sold, transferred, pledged or otherwise disposed of except pursuant
to an effective registration under such act or an exemption from
registration, which is available under such act.

4

 

     Certificates evidencing the Shares shall not be required to contain such legend or any other
legend (i) following any sale of such Shares pursuant to Rule 144, or (ii) if such Shares are
eligible for sale under Rule 144(b) or have been sold pursuant to the Registration Statement (as
defined in Section E hereof) and in compliance with the obligations set forth in Section E(6),
below, or (iii) such legend is not required under applicable requirements of the Securities Act
(including judicial interpretations and pronouncements issued by the Staff of the Securities and
Exchange Commission), in each such case (i) through (iii) to the extent reasonably determined by
the Company’s legal counsel. Subject to the foregoing, at such time and to the extent a legend is
no longer required for the Shares, the Company will use its reasonable best efforts to no later
than three (3) trading days following the delivery by a Purchaser to the Company or to the Company
and the Company’s transfer agent of a legended certificate representing such Shares (together with
such accompanying documentation or representations as reasonably required by counsel to the
Company), deliver or cause to be delivered a certificate representing such Shares that is free from
the foregoing legend.

     (10) If this Agreement is executed and delivered on behalf of a partnership, corporation,
limited liability company, trust, estate or other entity: (i) such partnership, corporation,
limited liability company, trust, estate or other entity has the full legal right and power and all
authority and approval required (a) to execute and deliver this Agreement and all other instruments
executed and delivered by or on behalf of such partnership, corporation, limited liability company,
trust, estate or other entity in connection with the purchase of its Securities, and (b) to
purchase and hold such Securities; (ii) the signature of the party signing on behalf of such
partnership, corporation, limited liability company, trust, estate or other entity is binding upon
such partnership, corporation, limited liability company, trust, estate or other entity; and (iii)
such partnership, corporation, limited liability company, trust or other entity has not been formed
for the specific purpose of acquiring such Securities, unless each beneficial owner of such entity
is qualified as an accredited investor within the meaning of Rule 501(a) of Regulation D
promulgated under the Securities Act and has submitted information to the Company substantiating
such individual qualification.

     (11) If such Purchaser is a retirement plan or is investing on behalf of a retirement plan,
such Purchaser acknowledges that an investment in the Securities poses additional risks, including
the inability to use losses generated by an investment in the Securities to offset taxable income.

     (12) The information contained in the purchaser questionnaire in the form of Exhibit
C attached hereto (the “Purchaser Questionnaire”) delivered by such Purchaser in
connection with this Agreement is complete and accurate in all respects, and such Purchaser is an
“accredited investor” as defined in Rule 501 of Regulation D under the Securities Act on the basis
indicated therein.

     (13) The information contained in the selling stockholder questionnaire in the form of
Exhibit D attached hereto (the “Selling Stockholder Questionnaire”) delivered by
such Purchaser in connection with this Agreement is complete and accurate in all material respects.

5

 

     (14) Such Purchaser acknowledges that the Company will have the authority to issue shares
of Common Stock, in excess of those being issued in connection with the Offering, and that the
Company may issue additional shares of Common Stock from time to time. The issuance of additional
shares of Common Stock may cause dilution of the existing shares of Common Stock and a decrease in
the market price of such existing shares. Such Purchaser acknowledges and agrees that such
Purchaser shall have no preemptive rights, right of first refusal, or other rights to subscribe for
or purchase any shares of Common Stock the Company may issue in the future as a result of such
Purchaser’s purchase of Securities pursuant to this Agreement.

     (15) Such Purchaser acknowledges that the Company has engaged Roth Capital Partners, LLC
(the “Placement Agent”) in connection with the Offering and, as consideration for its
services, has agreed to pay the Placement Agent an aggregate cash commission equal to five percent
(5%) of the gross proceeds resulting from those Purchasers which the Placement Agent has been
responsible for introducing to the Company for the purpose of participating in the Offering. The
Company has agreed to pay an advisory fee to the Placement Agent of $100,000, which amount will be
credited against the commission in the previous sentence.

     (16) Prohibited Transactions. Such Purchaser agrees that beginning on the date
hereof until the Offering is publicly announced by the Company (which the Company has agreed to
undertake in accordance with the provisions of Section F.(3) hereof), such Purchaser will not enter
into any Short Sales. For purposes of the foregoing sentence, a “Short Sale” by a
Purchaser means a sale of Common Stock that is marked as a short sale and that is executed at a
time when such Purchaser has no equivalent offsetting long position in the Common Stock, exclusive
of the Shares. For purposes of determining whether a Purchaser has an equivalent offsetting long
position in the Common Stock, all Common Stock that would be issuable upon exercise in full of all
options, warrants or convertible securities then held by such Purchaser (assuming that such options
were then fully exercisable or convertible, notwithstanding any provisions to the contrary, and
giving effect to any exercise price adjustments scheduled to take effect in the future) shall be
deemed to be held long by such Purchaser. Such Purchaser understands and acknowledges that the SEC
currently takes the position that coverage of Short Sales “against the box” prior to the effective
date of an applicable Registration Statement is a violation of Section 5 of the Securities Act, as
set forth in Item 65, Section A, of the Manual of Publicly Available Telephone Interpretations,
dated July 1997, complied by the Office of Chief Counsel, Division of Corporation Finance.

C. Representations and Warranties of the Company

     The Company hereby makes the following representations and warranties to the Purchasers as of
immediately prior to Closing after giving effect to the Plan of Reorganization and Confirmation
Order:

     (1) Organization, Good Standing and Qualification. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of Delaware and,
except as disclosed in the Disclosure Statement and the SEC Filings, the Company has full corporate

to do business as a foreign corporation and is in good standing in all jurisdictions

results of operations of the Company and its subsidiaries taken as a whole (a “Material Adverse
Effect”).

     (2) Capitalization. The authorized capital stock of the Company consists of
150,000,000 shares of Common Stock and 5,000,000 shares of preferred stock, par value $0.001 per

or enter into any such option, warrant, call, right, commitment or agreement.

     (3) Issuance; Reservation of Shares. The issuance of the Shares has been duly and

          (a) The execution and delivery by the Company of this Agreement and the consummation of the

the terms or provisions of, or constitute (with due notice or lapse of time or both) a default
under, any lease, loan agreement, mortgage, security agreement, trust indenture or other agreement
or instrument to which the Company or any of its subsidiaries is a party or by which it is bound

complied with or waived.

          (b) No consent, approval, authorization or other order of any governmental authority or other

Effect. Except for the Case, there is no action, suit, proceeding, inquiry or investigation before
or by any court, public board or body (including, without limitation, the SEC) pending or, to the
knowledge of the Company, threatened against or affecting the Company or any of its subsidiaries
wherein an unfavorable decision, ruling or finding could adversely affect the validity or
enforceability of, or the authority or ability of the Company to perform its obligations under this
Agreement. Except as disclosed in the Disclosure Statement and the SEC Filings in connection with
the Case, neither the Company nor any of its subsidiaries are subject to any order, judgment or
decree, which would be reasonably likely to have a Material Adverse Effect.

outstanding secured and unsecured Indebtedness (as defined below) of the Company or any subsidiary,
or for which the Company or any subsidiary has commitments. Neither the Company nor any of its

and the SEC Filings, there are no loans, leases, agreements, contracts, royalty agreements,
management contracts or arrangements or other continuing transactions between (a) the Company, its

other hand, any person who would be covered by Item 404(a) of Regulation S-K or any company or
other entity controlled by such person.

     (13) Taxes. The Company and its subsidiaries have prepared and filed all federal,
state, local, foreign and other tax returns for income, gross receipts, sales, use and other taxes
and custom duties (“Taxes”) required by law to be filed by them, except for tax returns,
the failure to file which, individually or in the aggregate, do not and would not have a Material
Adverse Effect. Such filed tax returns are complete and accurate, except for such omissions and
inaccuracies, which individually or in the aggregate, could not reasonably be expected to have a
Material Adverse Effect. The Company and its subsidiaries have paid or made provisions for the

9

 

payment of all Taxes shown to be due on such tax returns and all additional assessments, and
adequate provisions have been and are reflected in the financial statements of the Company and the
subsidiaries for all current Taxes to which the Company or any subsidiary is subject and which are
not currently due and payable, except for such Taxes which, if unpaid, individually or in the
aggregate, do not and would not have a Material Adverse Effect. None of the federal income tax
returns of the Company or any of its subsidiaries for the past five years has been audited by the
Internal Revenue Service. Neither the Company nor any of its subsidiaries has received written
notice of any assessments, adjustments or contingent liability (whether federal, state, local or
foreign) in respect of any Taxes pending or threatened against the Company or any subsidiary for
any period which, if unpaid, would have a Material Adverse Effect.

     (14) Insurance. The Company and its subsidiaries are insured by insurers of
recognized financial responsibility against such losses and risks and in such amounts as the
Company believes are prudent and customary in the businesses in which the Company and its
subsidiaries are engaged. The Company has no reason to believe that it will not be able to renew
its existing insurance coverage as and when such coverage expires or to obtain similar coverage
from similar insurers as may be necessary to continue its and its subsidiaries’ businesses without
an increase in cost significantly greater than general increases in cost experienced for similar
companies in similar industries with respect to similar coverage.

     (15) Environmental Matters. To the Company’s knowledge, all real property owned,
leased or otherwise operated by the Company and its subsidiaries is free of contamination from any
substance, waste or material currently identified to be toxic or hazardous pursuant to, within the

under, any Environmental Law (as defined below), including, without limitation, any asbestos,
polychlorinated biphenyls, radioactive substance, methane, volatile hydrocarbons, industrial
solvents, oil or petroleum or chemical liquids or solids, liquid or gaseous products, or any other
material or substance (“Hazardous Substance”) which has caused or would reasonably be
expected to cause or constitute a threat to human health or safety, or an environmental hazard in
violation of Environmental Law or to result in any environmental liabilities that would be
reasonably likely to have a Material Adverse Effect. Neither the Company nor any of its
subsidiaries has caused or suffered to occur any release, spill, migration, leakage, discharge,
disposal, uncontrolled loss, seepage, or filtration of Hazardous Substances that would reasonably
be expected to result in environmental liabilities that would be reasonably likely to have a
Material Adverse Effect. The Company and its subsidiaries have generated, treated, stored and
disposed of any Hazardous Substances in compliance with applicable Environmental Laws, except for
such non-compliances that would not be reasonably likely to have a Material Adverse Effect. The
Company and its subsidiaries have obtained, or has applied for, and is in compliance with and in
good standing under all permits required under Environmental Laws (except for such failures that
would not be reasonably likely to have a Material Adverse Effect) and neither the Company nor any
of its subsidiaries has knowledge of any proceedings to substantially modify or to revoke any such
permit. There are no investigations, proceedings or litigation pending or, to the Company’s
knowledge, threatened against the Company, its subsidiaries or any of their respective facilities
relating to Environmental Laws or Hazardous Substances. “Environmental Laws” shall mean
all federal, national, state, regional and local laws, statutes, ordinances and regulations, in
each case as amended or supplemented from time to time, and any judicial or

10

 

administrative interpretation thereof, including orders, consent decrees or judgments relating
to the regulation and protection of human health, safety, the environment and natural resources.

Statement and the SEC Filings, (a) the Company and its subsidiaries own or have the right to use
any and all information, know-how, trade secrets, patents, copyrights, trademarks, trade names,
software, formulae, methods, processes and other intangible properties that are of a such nature
and significance to the business that the failure to own or have the right to use such items would
have a Material Adverse Effect (“Intangible Rights”); (b) neither the Company nor any of
its subsidiaries has received any notice that it is in conflict with or infringing upon the
asserted intellectual property rights of others in connection with the Intangible Rights, and, to
the Company’s knowledge, neither the use of the Intangible Rights nor the operation of the
Company’s and its subsidiaries’ businesses is infringing or has infringed upon any intellectual
property rights of others in a manner that would be reasonably expected to have a Material Adverse
Effect; (c) all payments have been duly made that are necessary to maintain the Intangible Rights
in force; (d) no claims have been made, and to the Company’s knowledge, no claims are threatened,
that challenge the validity or scope of any material Intangible Right of the Company or any of its

in material breach of any such license or other permission in a manner that would be reasonably
expected to have a Material Adverse Effect.

     (17) Labor, Employment and Benefit Matters.

          (a) There are no existing, or to the Company’s knowledge, threatened strikes or other labor
disputes against the Company or any of its subsidiaries that would be reasonably likely to have a
Material Adverse Effect. There is no organizing activity involving employees of the Company or
its subsidiaries pending or, to the Company’s knowledge, threatened by any labor union or group of
employees. There are no representation proceedings pending or, to the Company’s knowledge,
threatened with the National Labor Relations Board, and no labor organization or group of

material respects with all applicable laws, including, to the extent applicable, U.S. anti-money

Effect. Neither the Company or its subsidiaries has received any notice of, nor does the Company
have any knowledge of, any violation (or of any investigation, inspection, audit or other
proceeding by any governmental entity involving allegations of any violation) of any applicable law
involving or related to the Company or any of its subsidiaries which has not been dismissed or
otherwise disposed of that would be reasonably likely to have a Material Adverse Effect. Neither
the Company nor any of its subsidiaries has received notice or otherwise has any knowledge that the

12

 

     (20) No Integrated Offering. Assuming the accuracy of each Purchaser’s
representations and warranties set forth in Section B hereof, neither the Company, nor any of its
affiliates or other person acting on the Company’s behalf has, directly or indirectly, made any
offers or sales of any security or solicited any offers to buy any security under circumstances
that would cause the Offering of the Securities to be integrated with prior offerings by the
Company for purposes of the Securities Act, when integration would cause the Offering not to be
exempt from the requirements of Section 5 of the Securities Act.

     (21) General Solicitation. Neither the Company nor, to its knowledge, any person
acting on behalf of the Company, has offered or sold any of the Securities by any form of “general
solicitation” within the meaning of Rule 502 under the Securities Act. To the knowledge of the

Purchasers and certain other “accredited investors” within the meaning of Rule 501 under the
Securities Act.

     (22) No Manipulation of Stock. The Company has not taken and will not take, in
violation of applicable law, any action designed to or that might reasonably be expected to cause
or result in stabilization or manipulation of the price of the Common Stock to facilitate the sale

made by, and compliance with the covenants of, the Purchasers, no registration of the Securities
under the Securities Act (other than as contemplated by Section E hereof) is required in connection
with the offer and sale of the Securities by the Company to the Purchasers as contemplated by this
Agreement.

     (24) Disclosure. The Company understands and acknowledges that each of the Purchasers
will rely on the foregoing representations in purchasing the Securities of the Company hereunder.
All disclosure provided by the Company to the Purchasers in the Company’s SEC Filings and the
Disclosure Statement regarding the Company, its business and the transactions contemplated hereby
furnished by or on the behalf of the Company are, taken as a whole, true and correct in all
material respects and do not contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements made therein, in the light of the
circumstances under which they were made, not misleading. To the Company’s knowledge, no material
event or circumstance has occurred or information exists with respect to the Company or its
business, properties, operations or financial conditions, which, under applicable law, rule or
regulation, requires public disclosure or announcement by the Company but which has not been so
publicly announced or disclosed.

D. Understandings

     Each of the Purchasers understands, acknowledges and agrees with the Company as follows:

     (1) The execution of this Agreement by the Purchaser or solicitation of the investment
contemplated hereby shall create no obligation on the part of the Company to accept any
subscription or complete the Offering. If the Company accepts a subscription for Securities

13

 

made by a Purchaser, it shall countersign this Agreement. If this Agreement is not
countersigned by the later of (i) five (5) business days following the Company’s receipt thereof,
and (ii) one (1) business day after entry of the Confirmation Order by the Bankruptcy Court
approving the Plan of Reorganization, the Purchaser shall have the option to withdraw its
investment by delivering written notice thereof to the Company. This Agreement, however, shall
remain valid unless and until the Company has received such written notice of withdrawal. Each
Purchaser hereby acknowledges and agrees that the subscription hereunder, once accepted by the
Company, is irrevocable by such Purchaser, and that, except as required by law, such Purchaser is
not entitled to cancel, terminate or revoke this Agreement or any agreements of such Purchaser
hereunder, except that the obligations under this Agreement shall not survive the death or
disability of such Purchaser.

     (2) No federal or state agency or authority has made any finding or determination as to the
accuracy or adequacy of the Offering Documents or as to the fairness of the terms of the Offering
nor any recommendation or endorsement of the Securities. Any representation to the contrary is a
criminal offense. In making an investment decision, Purchasers must rely on their own examination
of the Company and the terms of the Offering, including the merits and risks involved.

     (3) The Offering is intended to be exempt from registration under the Securities Act by virtue
of Section 4(2) of the Securities Act and the provisions of Rule 506 of Regulation D thereunder,
which is in part dependent upon the truth, completeness and accuracy of the statements made by the
Purchaser herein and in the Purchaser Questionnaire.

     (4) Notwithstanding the registration obligations provided herein, there can be no assurance
that the Purchaser will be able to sell or dispose of the Securities. It is understood that in
order not to jeopardize the Offering’s exempt status under Section 4(2) of the Securities Act and
Regulation D, any transferee may, at a minimum, be required to fulfill the investor suitability
requirements thereunder.

     (5) The Purchaser acknowledges that the Offering is confidential and non-public and agrees
that all information about the Offering shall be kept in confidence by the Purchaser until the
public announcement of the Offering by the Company. The Purchaser acknowledges that the foregoing
restrictions on the Purchaser’s use and disclosure of any such confidential, non-public information
contained in the above-described documents restricts the Purchaser from trading in the Company’s
securities to the extent such trading is on the basis of material, non-public information of which
the Purchaser is aware. Except for the terms of the transaction documents and the fact that the
Company is considering consummating the transactions contemplated therein (which information the
Company has agreed to disclose in accordance with Section F.(3) hereof), the Company confirms that
neither the Company nor, to its knowledge, any other person acting on its behalf, has provided any
of the Purchasers or their agents or counsel with any information that constitutes material,
non-public information as of the Closing Date.

Securities Act, including the Registration Statement, or such Registrable Securities have been
disposed of under Rule 144 promulgated under the Securities Act or (ii) such Registrable

actual filing, the “Filing Date”). The Registration Statement shall be on Form S-3;
provided that if the Company shall determine in good faith that Form S-3 is not then available to
it, the Registration Statement shall be on Form S-1. Each Purchaser will furnish to the Company,
within five (5) business days after request by the Company, a completed questionnaire in the form
set forth as Exhibit D hereto. Each Purchaser agrees to promptly update such questionnaire
in order to make the information previously furnished to the Company by such Purchaser complete
and not materially misleading. The Registration Statement shall register the Registrable
Securities for resale by the holders thereof.

          (b) The Company shall use its best efforts to cause the Registration Statement to be declared
effective by the SEC on or prior to the 150th day following the Closing (the

          (c) The Company shall request effectiveness of the Registration Statement (and any
post-effective amendments thereto) within five (5) business days following the Company’s receipt
of notice from the SEC that the Registration Statement will not be reviewed by the SEC or that the

amendments thereto) at 5:00 p.m., New York City time, on the effective date, and file with the SEC
and deliver the Prospectus (or any supplements thereto), which delivery may be made
electronically, by 8:00 a.m. New York City time on the business day after such effective date.

     (3) Registration Procedures. In connection with the Company’s registration
obligations hereunder, the Company shall:

          (a) Use its best efforts to (i) prepare and file with the SEC such amendments, including
post-effective amendments, to the Registration Statement as may be necessary to keep the
Registration Statement continuously effective as to the Registrable Securities for the
Effectiveness Period; (ii) cause the related Prospectus to be amended or supplemented by any
required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule

receives notice in writing of any suspension of the qualification or exemption from qualification
of any Registrable Securities for sale in any jurisdiction, or the initiation or threat of any
Proceeding for such purpose; or (vi) the financial statements included in the Registration
Statement become ineligible for inclusion therein or any statement made in the Registration
Statement or Prospectus or any document incorporated or deemed to be incorporated therein by
reference is untrue in any material respect or any revision to the Registration Statement,
Prospectus or other document is required so that it will not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were made, not
misleading. Notwithstanding the foregoing, the Company shall not

16

 

include any material non-public information in any notice provided to any Purchaser under
this Section E(3)(b).

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

          (d) Use its reasonable best efforts to deliver to each Purchaser, which delivery may be made
electronically, by 8:00 a.m. New York City time on the business day after the date first
available, without charge, such reasonable number of copies of the Prospectus or Prospectuses
(including each form of prospectus) and each amendment or supplement thereto as such Purchasers
may reasonably request. The Company hereby consents (except during the continuance of any event
described in Sections E(3)(b)(iii)-(vi) above) to the use of such Prospectus and each amendment or
supplement thereto by each of the selling Purchasers in connection with the offering and sale of
the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

          (e) In the event the Company’s Common Stock is then listed on the Nasdaq Capital Market: (i)
In the time and manner required by the Nasdaq Stock Market, Inc., prepare and file with Nasdaq
Stock Market, Inc. an additional shares listing application covering all of the Registrable
Securities and a notification form regarding the change in the number of the Company’s outstanding
Shares; (ii) use its reasonable best efforts to take all steps reasonably necessary to cause such
Registrable Securities to be approved for listing on the Nasdaq Capital Market as soon as possible
thereafter; (iii) provide to the Purchasers notice of such listing; and (iv) use its reasonable
best efforts to maintain the listing of such Registrable Securities on the Nasdaq Capital Market.

          (f) To the extent required by law, prior to any public offering of Registrable Securities,
use its reasonable best efforts to register or qualify or cooperate with the selling Purchasers in
connection with the registration or qualification (or exemption from such registration or
qualification) of such Registrable Securities for offer and sale under the securities or “blue
sky” laws of such jurisdictions within the United States as any Purchaser requests in writing, to
keep each such registration or qualification (or exemption therefrom) effective during the
Effectiveness Period and to do any and all other acts or things reasonably necessary or advisable
to enable the disposition in such jurisdictions of the Registrable Securities covered by a
Registration Statement; provided, however, that the Company shall not be required for any such
purpose to (i) qualify generally to do business as a foreign corporation in any jurisdiction
wherein it would not be otherwise required to qualify but for the requirements of this Paragraph
(3)(f), (ii) file any general consent to service of process in any jurisdiction where it is not as
of the date hereof so subject, or (iii) otherwise subject itself to taxation.

          (g) Upon the occurrence of any event described in Sections E(3)(b)(iii)-(vi) above, as
promptly as reasonably possible, prepare a supplement or amendment, including a post-effective
amendment, to the Registration Statement or a supplement to the related Prospectus or any document
incorporated or deemed to be incorporated therein by reference,

17

 

and file any other required document so that, as thereafter delivered, neither the
Registration Statement nor such Prospectus will contain an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading; provided,
however, that the Company may suspend sales pursuant to the Registration Statement for a period of
up to twenty (20) consecutive days or for a total of not more than forty-five (45) days in any
twelve-month period if the Company furnishes to the holders of the Registrable Securities a
certificate signed by the Company’s Chief Executive Officer stating that in the good faith
judgment of the Company’s Board of Directors, there is some material development relating to the
operations or condition (financial or other) of the Company that has not been disclosed to the
general public and as to which it is in the Company’s best interests not to disclose such
development, and the Company shall not disclose such development to the Purchasers.

          (h) The Company shall effect a filing with respect to the public offering contemplated by the
Registration Statement (an “Issuer Filing”) with the NASD Corporate Financing Department
pursuant to NASD Rule 2710 (b)(4)(A)(i) within one trading day of the Filing Date and pay the
filing fee required by such Issuer Filing. The Company shall use reasonable best efforts to
pursue the Issuer Filing until the NASD issues a letter confirming that it does not object to the
terms of the offering contemplated by the Registration Statement.

     (4) Registration Expenses. The Company shall pay (or reimburse the Purchasers for)
all fees and expenses incident to the performance of or compliance with this Agreement by the
Company, including without limitation (a) all registration and filing fees and expenses, including
without limitation those related to filings with the SEC, Nasdaq and in connection with applicable
state securities or “Blue Sky” laws, (b) printing expenses (including, without limitation, expenses
of printing certificates for Registrable Securities and of printing copies of Prospectuses
reasonably requested by the Purchasers), (c) messenger, telephone and delivery expenses, (d) and
fees and expenses of all other persons retained by the Company in connection with the consummation
of the transactions contemplated by this Agreement. Notwithstanding the foregoing, each Purchaser
shall pay any and all costs, fees, discounts or commissions attributable to the sale of its
respective Registrable Securities.

     (5) Indemnification.

          (a) Indemnification by the Company. In consideration of each Purchaser’s execution
and delivery of this Agreement and in addition to the Company’s other obligations hereunder, the
Company shall, notwithstanding any termination of this Agreement, indemnify, defend, protect and
hold harmless each Purchaser, its officers and directors, partners, members, agents, brokers and
employees of each of them, each person who controls any such Purchaser (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors,
partners, members, agents and employees of each such controlling person, and each underwriter of
Registrable Securities, to the fullest extent permitted by applicable law, from and against any
and all losses, claims, damages, liabilities, settlement costs and expenses, including without
limitation costs of preparation and reasonable attorneys’ fees (collectively, “Losses”),
as incurred, arising out of or relating to (A) any untrue or alleged untrue statement of a
material fact contained in the Registration Statement, any Prospectus or form of prospectus or in
any amendment or supplement thereto, or arising out of or relating to

18

 

any omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in the light of the circumstances under which they were made) not misleading,
except to the extent, but only to the extent, that (i) such untrue statements or omissions are
based upon information regarding such Purchaser furnished in writing to the Company by such
Purchaser expressly for use therein, or to the extent that such information related to such
Purchaser or such Purchaser’s proposed method of distribution of Registrable Securities and was
reviewed and expressly approved in writing by such Purchaser expressly for use in the Registration
Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto
(which shall, however, be deemed to include disclosure substantially in accordance with the “Plan
of Distribution” attached hereto), or (ii) in the case of an occurrence of an event of the type
specified in Paragraph (3)(b) above, the use by such Purchaser of an outdated or defective
Prospectus after the Company has duly notified such Purchaser in writing that the Prospectus is
outdated or defective and prior to the receipt by such Purchaser of the Advice contemplated in
Paragraph (6) below; (B) any misrepresentation or material breach of any representation or
warranty made by the Company in the Offering Documents; or (C) any material breach of any
covenant, agreement or obligation of the Company contained in the Offering Documents. The Company
shall notify the Purchasers promptly of the institution, threat or assertion of any Proceeding of
which the Company is aware in connection with the transactions contemplated by this Agreement.

          (b) Indemnification by Purchasers. Each Purchaser shall, severally and not jointly,
indemnify and hold harmless the Company, its directors, officers, agents and employees, and each
person who controls the Company (within the meaning of Section 15 of the Securities Act and
Section 20 of the Exchange Act), and the directors, officers, agents or employees of such
controlling persons, to the fullest extent permitted by applicable law, from and against all
Losses (as determined by a court of competent jurisdiction in a final judgment not subject to
appeal or review) arising out of or based upon any untrue statement or alleged untrue statement of
a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus
or in any amendment or supplement thereto, or arising out of or based upon any omission of a
material fact required to be stated therein or necessary to make the statements therein not
misleading to the extent, but only to the extent, that such untrue statement or omission is
contained in any information furnished in writing by such Purchaser to the Company specifically
for inclusion in such Registration Statement or Prospectus or to the extent that (i) such untrue
statements or omissions are based upon information regarding such Purchaser furnished in writing
to the Company by such Purchaser expressly for use therein, or to the extent that such information
related to such Purchaser or such Purchaser’s proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Purchaser expressly for use
in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or
supplement thereto (which shall, however, be deemed to include disclosure substantially in
accordance with the “Plan of Distribution” attached hereto), or (ii) in the case of an occurrence
of an event of the type specified in Paragraph (3)(b) above, the use by such Purchaser of an
outdated or defective Prospectus after the Company has notified such Purchaser in writing that the
Prospectus is outdated or defective and prior to the receipt by such Purchaser of the Advice
contemplated in Paragraph (6) below. In no event shall the liability of any selling Purchaser
hereunder be

19

 

greater in amount than the dollar amount of the net proceeds received by such Purchaser upon
the sale of the Registrable Securities giving rise to such indemnification obligation.

          (c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or
asserted against any person entitled to indemnity hereunder (an “Indemnified Party”), such
Indemnified Party shall promptly notify the person from whom indemnity is sought (the
“Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense
thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and
the payment of all fees and expenses incurred in connection with defense thereof, provided, that
the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party
of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that
such failure shall have prejudiced the Indemnifying Party. An Indemnified Party shall have the
right to employ separate counsel in any such Proceeding and to participate in the defense thereof,
but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or
Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; or
(ii) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding
and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or
(iii) the named parties to any such Proceeding (including any impleaded parties) include both such
Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised
by counsel that a conflict of interest is likely to exist if the same counsel were to represent
such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party
notifies the Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the
defense thereof and such counsel shall be at the expense of the Indemnifying Party; provided,
however, that in the event that the Indemnifying Party shall be required to pay the fees and
expenses of separate counsel, the Indemnifying Party shall only be required to pay the fees and
expenses of one separate counsel for such Indemnified Party or Parties. The Indemnifying Party
shall not be liable for any settlement of any such Proceeding affected without its written
consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any pending
Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes
an unconditional release of such Indemnified Party from all liability on claims that are the
subject matter of such Proceeding. All fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with investigating or preparing
to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the
Indemnified Party, as incurred, within ten trading days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is
not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such
Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally
judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

          (d) Contribution. If a claim for indemnification under Paragraph (5)(a) or (b) is
unavailable to an Indemnified Party (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount
paid or payable by such Indemnified Party as a result of such Losses, in such

20

 

proportion as is appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that resulted in such
Losses as well as any other relevant equitable considerations. The relative fault of such
Indemnifying Party and Indemnified Party shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement of a material
fact or omission or alleged omission of a material fact, has been taken or made by, or related to
information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such action,
statement or omission. The amount paid or payable by a party as a result of any Losses shall be
deemed to include, subject to the limitations set forth in Paragraph (5)(c), any reasonable
attorneys’ or other reasonable fees or expenses incurred by such party in connection with any
Proceeding to the extent such party would have been indemnified for such fees or expenses if the
indemnification provided for in this Paragraph 5(d) was available to such party in accordance with
its terms.

     The parties hereto agree that it would not be just and equitable if contribution pursuant to
this Paragraph (5)(d) were determined by pro rata allocation or by any other method of allocation
that does not take into account the equitable considerations referred to in the immediately
preceding paragraph. Notwithstanding the provision of this Paragraph (5)(d), no Purchaser shall be
required to contribute, in the aggregate, any amount in excess of the amount of net proceeds
actually received by such Purchaser from the sale of the Registrable Securities subject to the
Proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
of the Securities Act) shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

     The indemnity and contribution agreements contained in this Section are in addition to any
liability that the Indemnifying Parties may have to the Indemnified Parties and any cause of action
or similar right of the Indemnified Parties against the Indemnifying Parties or others.

     (6) Dispositions. Each Purchaser agrees that it will comply with the prospectus
delivery requirements of the Securities Act as applicable to it in connection with sales of
Registrable Securities pursuant to the Registration Statement. Each Purchaser further agrees that,
upon receipt of a notice from the Company of the occurrence of any event of the kind described in
Paragraphs (3)(b), such Purchaser will discontinue disposition of such Registrable Securities under
the Registration Statement until such Purchaser’s receipt of the copies of the supplemented
Prospectus and/or amended Registration Statement contemplated by Paragraph (3)(g), or until it is
advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus
may be resumed, and, in either case, has received copies of any additional or supplemental filings
that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration
Statement. The Company may provide appropriate stop orders to enforce the provisions of this
paragraph.

     (7) Piggy-Back on Registrations. Except for Bio-Rad pursuant to the terms of the
Bio-Rad Stock Purchase Agreement and (ii) Quest pursuant to the terms of the Quest Stock Purchase
Agreement, neither the Company nor any of its security holders may include securities of the
Company in the Registration Statement other than the Registrable Securities, and the

21

 

Company shall not after the date hereof enter into any agreement providing any such right with
respect to the Registration Statement to any of its security holders.

     (8) Piggy-Back Registrations. If at any time during the Effectiveness Period, other
than any suspension period referred to in Section E(3)(g) above, there is not an effective
Registration Statement covering all of the Registrable Securities and the Company shall determine
to prepare and file with the SEC a registration statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity securities, other
than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then
equivalents relating to equity securities to be issued solely in connection with any acquisition of
any entity or business or equity securities issuable in connection with stock option or other
employee benefit plans, then the Company shall send to each Purchaser written notice of such
determination and if, within ten (10) days after receipt of such notice, any such Purchaser shall
so request in writing, the Company shall use its reasonable best efforts to include in such
registration statement all or any part of such Registrable Securities not already covered by an
effective Registration Statement such Purchaser requests to be registered; provided, however, that
the Company shall have the right to postpone or withdraw any registration effected pursuant to this
Section E(8).

     If the registration of which the Company gives notice is for a registered public offering
involving an underwriting, the Company shall so indicate in the notice given pursuant to this
Section E(9). In such event the right of any Purchaser to registration pursuant to this Section
E(9) shall be conditioned upon Purchaser’s agreeing to participate in such underwriting and in the
inclusion of such Purchaser’s Registrable Securities in the underwriting to the extent provided
herein. The Purchaser shall (together with the Company and the other holders distributing their
securities through such underwriting) enter into an underwriting agreement in customary form with
the underwriter or underwriters selected for such underwriting by the Company or by other holders
exercising any demand registration rights. Notwithstanding any other provision of this Section
E(9), if the underwriter determines that marketing factors require a limitation of the number of
shares to be underwritten, the underwriter may exclude some or all Registrable Securities or other
securities from such registration and underwriting (hereinafter an “Underwriter Cutback”).
In the event of an Underwriter Cutback, the Company shall so advise the Purchaser and the other
holders distributing their securities through such underwriting, and the number of Registrable
Securities that may be included in the registration and underwriting shall be allocated in
proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by
the Purchaser and the other holders distributing their securities through such underwriting at the
time of filing the registration statement. If any Purchaser disapproves of the terms of any such
underwriting, such Purchaser may elect to withdraw therefrom by written notice to the Company and
the underwriter. Any securities excluded or withdrawn from such underwriting shall be withdrawn
from such registration.

     (9) Rule 144. Until the earlier of (i) one year following the effectiveness of the
Registration Statement and (ii) the date when such Registrable Securities may be sold without
registration or restriction pursuant to Rule 144(b) under the Securities Act or any successor
provision, the Company agrees with each holder of Registrable Securities to:

22

 

          (a) use its best efforts to comply with the requirements of Rule 144(c) under the Securities
Act with respect to current public information about the Company;

          (b) use its best efforts to file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act (at any time it is
subject to such reporting requirements); and

          (c) furnish to any holder of Registrable Securities upon request (i) a written statement by
the Company as to its compliance with the requirements of said Rule 144(c) and the reporting
requirements of the Securities Act and the Exchange Act (at any time it is subject to such
reporting requirements), (ii) a copy of the most recent annual or quarterly report of the Company,
and (iii) such other reports and documents of the Company as such holder may reasonably request to
avail itself of any similar rule or regulation of the SEC allowing it to sell any such securities
without registration.

F. Covenants of the Company

terms of the transaction documents by issuing a press release and filing with the SEC a Current

date of this Agreement. As a result of the forgoing issuance and filing, all material, non-public
information previously provided to the Purchasers or their agents or counsel shall have been

following the foregoing issuance and filing the Company shall have no obligation to, and will not,

exchange, in the sole discretion of the Company, by no later than 180 days following the Closing.
The Company and the Purchasers expressly agree that the quotation of the Company’s Common Stock on
the “pink sheets” shall not be considered to satisfy the Company’s obligations pursuant to this
covenant.

     (4) The Company shall use its reasonable best efforts (i) to be in compliance with all of its
SEC filing obligations (including having made all filings under the Exchange Act that have not been
timely filed as of the date hereof) not later than the 120th day following the Closing and (ii)
thereafter, to file in a timely manner all required reports under the Exchange Act.

     (5) The Company agrees to file one or more Forms D with respect to the Securities on a timely
basis as required under Regulation D under the Securities Act to claim the exemption

23

the Securities Act.

     (7) The Company intends that the net proceeds from the Offering will be used to finance in
part the distributions to be made under the Plan of Reorganization, to pay the fees and expenses
associated therewith, to repay in full the Company’s obligations under its debtor-in-possession
financing agreement with Quest Diagnostics Incorporated, and for working capital and other general
corporate purposes of the Company and its subsidiaries, including, without limitation, to fund the
continued development of its diagnostic tests and other products and research and development.

     (3) Failure of the Company to exercise any right or remedy under this Agreement or any other
agreement between the Company and the Purchaser, or otherwise, or delay by the Company in
exercising such right or remedy, will not operate as a waiver thereof. No waiver by the Company
will be effective unless and until it is in writing and signed by the Company.

     (4) All questions concerning the construction, validity, enforcement and interpretation of
this Agreement shall be governed by the internal laws of the State of New York, without giving
effect to any choice of law or conflict of law provision or rule (whether of the State of New York
or any other jurisdictions) that would cause the application of the laws of any jurisdictions other
than the State of New York. Each party hereby irrevocably submits to the nonexclusive jurisdiction
of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in
any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of
any such court, that such suit, action or proceeding is brought in an inconvenient forum or that
the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives
personal service of process and consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address for such notices to it under this
Agreement and agrees that such service shall constitute good and sufficient service of process and
notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY
HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN
CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

     (5) This Agreement shall be binding upon and inure to the benefit of the parties and their
respective successors and assigns, including any purchasers of the Shares. The Company shall not
assign this Agreement or any rights or obligations hereunder without the prior written consent of
the holders of at least a majority of the aggregate number of Shares issued and issuable in
connection with the Offering. A Purchaser may assign some or all of its rights hereunder without
the consent of the Company, in which event such assignee shall be deemed to be a Purchaser
hereunder with respect to such assigned rights.

     (6) If any provision of this Agreement is held to be invalid or unenforceable under any
applicable statute or rule of law, then such provision shall be deemed modified to conform with
such statute or rule of law. Any provision hereof that may prove invalid or unenforceable under
any law shall not affect the validity or enforceability of any other provisions hereof.

     (7) The parties understand and agree that, unless provided otherwise herein, money damages
would not be a sufficient remedy for any breach of the Agreement by the Company or a Purchaser and
that the party against which such breach is committed shall be entitled to equitable relief,
including injunction and specific performance, as a remedy for any such breach. Such remedies
shall not, unless provided otherwise herein, be deemed to be the exclusive remedies for a breach by
either party of the Agreement but shall be in addition to all other remedies available at law or
equity to the party against which such breach is committed.

25

 

     (8) This Agreement is intended for the benefit of the parties hereto and their respective
permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be
enforced by, any other person.

     (9) The representations, warranties, covenants and agreements of the Company and the
Purchasers shall survive the Closing. Each Purchaser shall be responsible only for its own
representations, warranties, agreements and covenants hereunder.

     (10) The obligations of each Purchaser under this Agreement are several and not joint with the
obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the
performance of the obligations of any other Purchaser hereunder. Nothing contained herein, and no
action taken by any Purchaser pursuant hereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any similar entity, or create a presumption that
the Purchasers are in any way acting in concert or as a group with respect to such obligations or
the transactions contemplated hereby and the Company acknowledges, and each Purchaser confirms,
that the Purchasers are not acting in concert or as a group with respect to such obligations or the
transactions contemplated by this Agreement. The Company acknowledges and each Purchaser confirms
that it has independently participated in the negotiation of the transaction contemplated hereby
with the advice of its own counsel and advisors. Each Purchaser shall be entitled to independently
protect and enforce its rights, including, without limitation, the rights arising out of this
Agreement or out of any other Offering Documents, and it shall not be necessary for any other
Purchaser to be joined as an additional party in any proceeding for such purpose.

     (11) This Agreement, together with the agreements and documents executed and delivered in
connection with this Agreement, constitutes the entire agreement between the parties hereto with
respect to the subject matter hereof.

Exhibit A

Legal Matters

     Paul, Hastings, Janofsky & Walker LLP shall deliver an opinion covering the following matters.
The opinion shall be subject to and include customary assumptions, limitations and qualifications.

     1. The Company is a corporation, validly existing and in good standing under the laws of the
State of Delaware and has all requisite corporate power and authority under the laws of the State
of Delaware to enter into and perform its obligations under the Securities Purchase Agreement and
the Escrow Agreement (collectively, the “Agreements”).

     2. The authorized capital stock of the Company consists of 150,000,000 shares of common stock,
par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share.

     3. The Shares have been duly authorized or reserved for issuance by all necessary corporate
action on the part of the Company; and the Shares, when issued and delivered against payment
therefore in accordance with the provisions of the Securities Purchase Agreement, will be validly
issued, fully paid and non-assessable.

     4. The execution and delivery by the Company of the Agreements, and the consummation by the
Company of the transactions contemplated thereby, have been duly authorized by all necessary
corporate action on the part of the Company. The Agreements constitute the valid and binding
obligations of the Company, enforceable against the Company in accordance with their respective
terms.

     5. The execution and delivery by the Company of the Agreements, and the consummation by the
Company of the transactions contemplated thereby, do not (a) violate the provisions of any federal
law of the United States of America or the General Corporation Law of the State of Delaware
applicable to the Company; (b) violate the provisions of the Company’s Certificate of Incorporation
or By-laws; or, (c) to our knowledge, violate any existing obligation of the Company under any
judgment, decree, order or award of any court, governmental body or arbitrator specifically naming
the Company and of which we are aware, without any inquiry.

     6. Assuming (a) the accuracy of the representations made by each Purchaser in the Securities
Purchase Agreement; (b) that neither the Company, any placement agent nor any person acting on
behalf of either the Company or the Placement Agent has offered or sold the Securities by any form
of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D
(the “Regulation D”) promulgated under the Securities Act; (c) that no offerings or sales
of securities of the Company after the date hereof in a transaction can be “integrated” with any
sales of the Securities; and (d) that each person or entity that purchased securities of the
Company directly from the Company or its agents and without registration between the date six
months prior to the Closing of the Offering and the date of the Agreement was, as of the date of
such purchase, an “accredited investor” as defined in Rule 501 of Regulation D, the sale of the
Securities to the Purchasers at the Closing under the circumstances

 

 

contemplated by the Securities Purchase Agreement are exempt from the registration and prospectus
delivery requirements of Section 5 of the Securities Act.
