     This Registration Rights Agreement (this "Agreement") is made and entered
into as of December 29, 2005, by and between Aveta Inc., a Delaware corporation
(together with any successor entity thereto, the "Company"), and Friedman,
Billings, Ramsey & Co., Inc., a Delaware corporation ("FBR"), for the benefit of

of its common stock (the "Private Placement"), and the direct and indirect
transferees of FBR, and each of the Participants.

2. REGISTRATION RIGHTS

     (a) Mandatory Shelf Registration. As set forth in Section 4 hereof, the
Company agrees to file with the Commission as soon as reasonably practicable
following the date of this Agreement (but in no event later than the date that
is 90 days after the date of this Agreement) a shelf Registration Statement on
Form S-1 or such other form under the Securities Act then available to the
Company providing for the resale of any Registrable Shares pursuant to Rule 415
from time to time by the Holders (a "Shelf Registration Statement"). The Company
shall use its commercially reasonable efforts to cause such Shelf Registration
Statement to be declared effective by the Commission as soon as practicable (but
in no event later than 180 days after the date of this Agreement). Any Shelf
Registration Statement shall provide for the resale from time to time, and
pursuant to any method or combination of methods legally available (including,
without limitation, an Underwritten Offering, a direct sale to purchasers or a
sale through brokers


                                       5

<PAGE>


or agents, which may include sales over the Internet) by the Holders of any and
all Registrable Shares.

     (b) IPO Registration. If the Company proposes to file a registration
statement on Form S-1 or such other form under the Securities Act providing for
the initial public offering of shares of Common Stock (the "IPO Registration
Statement"), the Company will notify each Holder of the proposed filing and
afford each Holder an opportunity to include in the IPO Registration Statement
all or any part of the Registrable Shares then held by such Holder. Each Holder
desiring to include in the IPO Registration Statement all or part of the
Registrable Shares held by such Holder shall, within twenty (20) days after
receipt of the above-described notice from the Company, so notify the Company in
writing, and in such notice shall inform the Company of the number of
Registrable Shares such Holder wishes to include in the IPO Registration
Statement. Any election by any Holder to include any Registrable Shares in the
IPO Registration Statement will not affect the inclusion of such Registrable
Shares in the Shelf Registration Statement until such Registrable Shares have
been sold under the IPO Registration Statement.

          (i) Right to Terminate IPO Registration. The Company, in its sole
     discretion, shall have the right to terminate or withdraw the IPO
     Registration Statement initiated by it referred to in this Section 2(b)
     prior to the effectiveness of such registration whether or not any Holder
     has elected to include Registrable Shares in such registration.

          (ii) Selection of Underwriter. The Company shall have the sole right
     to select the managing underwriter(s) for its initial public offering,
     regardless of whether any Registrable Shares are included in the IPO
     Registration Statement or otherwise.

          (iii) Shelf Registration not Impacted by IPO Registration Statement.
     The Company's obligation to file the Shelf Registration Statement pursuant
     to Section 2(a) hereof shall not be affected by the filing or effectiveness
     of the IPO Registration Statement.

     (c) Underwriting. The Company shall advise all Holders of the underwriter
for the Underwritten Offering proposed under the IPO Registration Statement. The
right of any such Holder's Registrable Shares to be included in the IPO
Registration Statement pursuant to Section 2(b) shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Shares in the underwriting to the extent provided herein. All
Holders proposing to distribute their Registrable Shares through such
underwriting shall enter into an underwriting agreement in customary form with
the managing underwriter(s) selected for such underwriting and complete and
execute any questionnaires, powers of attorney, indemnities, securities escrow
agreements and other documents reasonably required under the terms of such
underwriting, and furnish to the Company such information as the Company may
reasonably request in writing for inclusion in the Registration Statement;
provided, however, that no Holder shall be required to make any representations
or warranties to or agreements with the Company or the underwriters other than
representations, warranties


                                        6

<PAGE>

or agreements regarding such Holder and such Holder's intended method of
distribution and any other representation required by law or reasonably
requested by the underwriters. Notwithstanding any other provision of this
Agreement, if the managing underwriter(s) determine(s) in good faith that
marketing factors require a limitation on the number of shares to be included,
then the managing underwriter(s) may exclude shares (including Registrable
Shares) from the IPO Registration Statement and Underwritten Offering, and any
shares included in such IPO Registration Statement and Underwritten Offering
shall be allocated first, to the Company, and second, to each of the Holders
requesting inclusion of their Registrable Shares in such IPO Registration
Statement (on a pro rata basis based on the total number of Registrable Shares
then held by each such Holder who is requesting inclusion); provided, however,
that the number of Registrable Shares to be included in the IPO Registration
Statement shall not be reduced unless all other securities of the Company held
by (i) officers, directors, other employees of the Company and consultants; and
(ii) other holders of the Company's capital stock with registration rights that
are inferior (with respect to such reduction) to the registration rights of the
Holders set forth herein, are first entirely excluded from the underwriting and
registration.

     Regardless of whether a Holder elects to include Registrable Shares in the
IPO Registration Statement, each Holder of such Registrable Shares shall be
deemed to have agreed not to effect any public sale or distribution of
securities of the Company of the same or similar class or classes of the
securities included in the IPO Registration Statement or any securities
convertible into or exchangeable or exercisable for such securities, including a
sale pursuant to Rule 144 or Rule 144A under the Securities Act, during such
periods as reasonably requested (but in no event for a period longer than sixty
(60) days following the effective date of the IPO Registration Statement) by the
representatives of the underwriters, if an Underwritten Offering, or by the
Company in any other registration.

     If any Holder disapproves of the terms of any such underwriting, such
Holder may elect to withdraw therefrom by written notice to the Company and the
underwriter, delivered at least ten (10) Business Days prior to the effective
date of the IPO Registration Statement. Any Registrable Shares excluded or
withdrawn from such underwriting shall be excluded and withdrawn from the
registration.

     (d) Expenses. The Company shall pay all Registration Expenses in connection
with the registration of the Registrable Shares pursuant to this Agreement. Each
Holder participating in a registration pursuant to this Section 2 shall bear
such Holder's proportionate share (based on the total number of Registrable
Shares sold in such registration) of all discounts and commissions payable to
underwriters or brokers in connection with a registration of Registrable Shares
pursuant to this Agreement.

     (e) Executive Bonuses. If (1) the Company does not file a Registration
Statement registering the resale of the Accredited Investor Shares, the Rule
144A Shares, and the Regulation S Shares within 90 days after the Closing Date
or (2) such Registration Statement is not declared effective within 180 days of
the Closing Date, other than as a result of the Commission being unable to
accept such filings (each a "Registration Default"), then Daniel E. Straus,
Chairman of the Company's Board of Directors, Timothy J. O'Donnell, the
Company's


                                        7

<PAGE>

Chief Executive Officer, and Joseph D. Mark, Chairman of the Company's Executive
Committee of the Board of Directors, shall each forfeit 1% of any cash bonus to
which he became entitled or earned as a result of performance during the 2006
fiscal year (whether or not payable in 2006)), whether under an employment
agreement with the Company, a bonus plan or any other bonus arrangement,
including any bonus compensation for which payment would otherwise be deferred
until after 2006, for each Business Day such Registration Default continues, up
to the maximum amount of each such bonus; provided, however, that such
forfeiture shall not apply at any time when the Company has endeavored in good
faith to file such Registration Statement within the time period specified but
is unable to make the filing as of the specified date as a result of
circumstances beyond the Company's reasonable control.

3. RULES 144 AND 144A REPORTING

     With a view to making available the benefits of certain rules and
regulations of the Commission that may at any time permit the sale of the
Registrable Shares to the public without registration, the Company agrees to:

after it has become subject to the reporting requirements of the Exchange Act),
(ii) a copy of the most recent annual or quarterly report of the Company, and
(iii) such other reports and documents of the Company, and take such further

Shares without registration; and

     (e) If the Company is not otherwise required to file reports and other
documents with the Commission, it will use commercially reasonable efforts to
make available such other information as required by, and so long as necessary

144A, and in any event will make available to holders of its common stock

release):

discuss such financial statements, with an opportunity for investors to ask
questions of the Company's management with respect to such financial statements.

Registrable Shares already in progress;

jurisdictions as FBR or any Holder of Registrable Shares covered by a
Registration Statement shall reasonably request in writing, keep each such
registration or qualification or exemption effective during the period such
Registration Statement is required to be kept effective pursuant to Section 4(a)
and do any and all other acts and things that may be reasonably necessary or
advisable to enable such Holder to consummate the disposition in each such
jurisdiction of such Registrable Shares owned by such Holder; provided, however,
that the Company shall not be required to (i) qualify generally to do business
in any jurisdiction or to register as a broker or dealer in such jurisdiction
where it would not otherwise be required to qualify but for this Section 4(d)
and except as may be required by the Securities Act, (ii) subject itself to
taxation in any such jurisdiction, or (iii) submit to the general service of
process in any such jurisdiction;

     (e) use its commercially reasonable efforts to cause all Registrable Shares
covered by such Registration Statement to be registered and approved by such
other governmental agencies


                                       10

or authorities as may be necessary to enable the Holders thereof to consummate
the disposition of such Registrable Shares;

     (f) notify FBR and each Holder promptly and, if requested by FBR or any
Holder, confirm such advice in writing (i) when a Registration Statement has
become effective and when any post-effective amendments and supplements thereto
become effective, (ii) of the issuance by the Commission or any state securities
authority of any stop order suspending the effectiveness of a Registration
Statement or the initiation of any proceedings for that purpose, (iii) of any
request by the Commission or any other federal, state or foreign governmental
authority for amendments or supplements to a Registration Statement or related
Prospectus or for additional information, (iv) of the happening of any event
during the period a Registration Statement is effective as a result of which
such Registration Statement or the related Prospectus or any document
incorporated by reference therein contains any untrue statement of a material
fact or omits to state any material fact required to be stated therein or
necessary to make the statements therein not misleading (which information shall
be accompanied by an instruction to suspend the use of the Prospectus until the
requisite changes have been made) and (v) at the request of any such Holder,
promptly to furnish to such Holder a reasonable number of copies of a supplement
to or an amendment of such Prospectus as may be necessary so that, as thereafter
delivered to the purchaser of such securities, such Prospectus shall not include
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not misleading;

     (g) use its commercially reasonable efforts to avoid the issuance of, or if
issued, to obtain, as promptly as practicable, the withdrawal of, any order
enjoining or suspending the use or effectiveness of a Registration Statement or
suspending of the qualification (or exemption from qualification) of any of the
Registrable Shares for sale in any jurisdiction;

     (h) upon the written request, furnish to each requesting Holder of
Registrable Shares, without charge, at least one conformed copy of each
Registration Statement and any post-effective amendment or supplement thereto
(without documents incorporated therein by reference or exhibits thereto, unless
requested);

     (i) except as provided in Section 5, upon the occurrence of any event
contemplated by Section 4(f)(iv) hereof, use its commercially reasonable efforts
to promptly prepare a supplement or post-effective amendment to a Registration
Statement or the related Prospectus or any document incorporated therein by
reference or file any other required document so that, as thereafter delivered
to the purchasers of the Registrable Shares, such Prospectus will not contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading;

     (j) if requested by the representative of the underwriters, if any, or any
Holders of Registrable Shares being sold in connection with such offering,
(i) promptly incorporate in a Prospectus supplement or post-effective amendment
such information as the representative of the underwriters, if any, or such
Holders indicate relates to them or that they reasonably request be included
therein and (ii) make all required filings of such Prospectus supplement or such
post-


                                       11

<PAGE>

effective amendment as soon as practicable after the Company has received
notification of the matters to be incorporated in such Prospectus supplement or
post-effective amendment;

     (k) in the case of an Underwritten Offering, use its commercially
reasonable efforts to furnish to the underwriters a signed counterpart,
addressed to the underwriters, of: (i) an opinion of counsel for the Company,
dated the date of each closing under the underwriting agreement, reasonably
satisfactory to the underwriters; and (ii) a "comfort" letter, dated the
effective date of such Registration Statement and the date of each closing under
the underwriting agreement, signed by the independent public accountants who
have certified the Company's financial statements included in such Registration
Statement, covering substantially the same matters with respect to such
Registration Statement (and the Prospectus included therein) and with respect to
events subsequent to the date of such financial statements, as are customarily
covered in accountants' letters delivered to underwriters in underwritten public
offerings of securities;

     (l) enter into customary agreements (including in the case of an
Underwritten Offering, an underwriting agreement in customary form) and take all
other action in connection therewith in order to expedite or facilitate the
distribution of the Registrable Shares included in such Registration Statement,
and, in the case of an Underwritten Offering, make representations and
warranties to the underwriters in such form and scope as are customarily made by
issuers to underwriters in underwritten offerings and confirm the same to the
extent customary if and when requested;

     (m) make available for inspection by representatives of the Holders and the
representative of any underwriters participating in any disposition pursuant to
a Registration Statement and any special counsel or accountants retained by such
Holders or underwriters, all financial and other records, pertinent corporate
documents and properties of the Company and cause the respective officers,
directors and employees of the Company to supply all information reasonably
requested by any such representatives, the representative of the underwriters,
counsel thereto or accountants in connection with a Registration Statement;
provided, however, that such records, documents or information that the Company
determines, in good faith, to be confidential and notifies such representatives,
representative of the underwriters, counsel thereto or accountants are
confidential shall not be disclosed by the representatives, representative of
the underwriters, counsel thereto or accountants unless (i) the disclosure of
such records, documents or information is necessary to avoid or correct a
misstatement or omission in a Registration Statement or Prospectus, (ii) the
release of such records, documents or information is ordered pursuant to a
subpoena or other order from a court of competent jurisdiction, or (iii) such
records, documents or information have been generally made available to the
public;

     (n) use its commercially reasonable efforts (including, without limitation,
seeking to cure any deficiencies cited by the exchange or market in the
Company's listing or inclusion application) to list or include all Registrable
Shares on the New York Stock Exchange, the American Stock Exchange or The Nasdaq
Stock Market;

     (o) prepare and file in a timely manner all documents and reports required
by the Exchange Act and, to the extent the Company's obligation to file such
reports pursuant to Section 15(d) of the Exchange Act expires prior to the
expiration of the effectiveness period of the Registration Statement as required
by Section 4(a) hereof, the Company shall register the


                                       12

<PAGE>

Registrable Shares under the Exchange Act and shall maintain such registration
through the effectiveness period required by Section 4(a) hereof;

     (p) provide a CUSIP number for all Registrable Shares, not later than the
effective date of the Registration Statement;

     (q) (i) otherwise use its commercially reasonable efforts to comply with
all applicable rules and regulations of the Commission, (ii) make generally
available to its stockholders, as soon as reasonably practicable, earnings
statements covering at least 12 months that satisfy the provisions of Section
1l(a) of the Securities Act and Rule 158 (or any similar rule promulgated under
the Securities Act) thereunder, but in no event later than forty-five (45) days
after the end of each fiscal year of the Company and (iii) not file any
Registration Statement or Prospectus or amendment or supplement to such
Registration Statement or Prospectus to which any Holder of Registrable Shares
covered by any Registration Statement shall have reasonably objected on the
grounds that such Registration Statement or Prospectus or amendment or
supplement does not comply in all material respects with the requirements of the
Securities Act, such Holder having been furnished with a copy thereof at least
two (2) Business Days prior to the filing thereof;

     (r) provide and cause to be maintained a registrar and transfer agent for
all Registrable Shares covered by any Registration Statement from and after a
date not later than the effective date of such Registration Statement;

     (s) in connection with any sale or transfer of the Registrable Shares
(whether or not pursuant to a Registration Statement) that will result in the
security being delivered no longer being Registrable Shares, cooperate with the
Holders and the representative of the underwriters, if any, to facilitate the
timely preparation and delivery of certificates representing the Registrable
Shares to be sold, which certificates shall not bear any transfer restrictive
legends (other than as required by The Depository Trust Company) and to enable
such Registrable Shares to be in such denominations and registered in such names
as the representative of the underwriters, if any, or the Holders may request at
least two (2) Business Days prior to any sale of the Registrable Shares;
provided, however, that such Holder has provided the Company with any documents
that are reasonably requested by the Company;

     (t) if required by the rules of the NASD, in connection with the initial
filing of a Shelf Registration Statement and each amendment thereto with the
Commission pursuant to Section 2(a) hereof, prepare and, within one Business Day
of such filing with the Commission, file with the NASD all forms and information
required or requested by the NASD in order to obtain written confirmation from
the NASD that the NASD does not object to the fairness and reasonableness of the
underwriting terms and arrangements (or any deemed underwriting terms and
arrangements) relating to the resale of Registrable Shares pursuant to the Shelf
Registration Statement, including, without limitation, information provided to
the NASD through its COBRADesk system, and pay all costs, fees and expenses
incident to the NASD's review of the Shelf Registration Statement and the
related underwriting terms and arrangements, including, without limitation, all
filing fees associated with any filings or submissions to the NASD and the legal
expenses, filing fees and other disbursements of FBR and any other NASD member
that is the holder of, or is affiliated or associated with an owner of,
Registrable Shares included in the


                                       13

<PAGE>

Shelf Registration Statement (including in connection with any initial or
subsequent member filing);

     (u) in connection with the initial filing of a Shelf Registration Statement
and each amendment thereto with the Commission pursuant to Section 2(a) hereof,
provide to FBR and its representatives, the opportunity to conduct reasonable
due diligence, including, without limitation, an inquiry of the Company's
financial and other records, and make available members of its management for
questions regarding information which FBR may request in order to fulfill any
due diligence obligation on its part; and

     (w) upon effectiveness of the first Registration Statement filed under this
Agreement, the Company will take such actions and make such filings as are
necessary to effect the registration of the Common Stock under the Exchange Act
simultaneously with or immediately following the effectiveness of the
Registration Statement.

     The Company may require the Holders to furnish to the Company such
information regarding the proposed distribution by such Holder of such
Registrable Shares as the Company may from time to time reasonably request in
writing or as shall be required to effect the registration of the Registrable
Shares, and no Holder shall be entitled to be named as a selling stockholder in
any Registration Statement and no Holder shall be entitled to use the Prospectus
forming a part thereof if such Holder does not provide such information to the
Company. Each Holder further agrees to furnish promptly to the Company in
writing all information required from time to time to make the information
previously furnished by such Holder not misleading.

     Each Holder agrees that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 4(f)(iii) or 4(f)(iv)
hereof, such Holder will immediately discontinue disposition of Registrable
Shares pursuant to a Registration Statement until such Holder's receipt of the
copies of the supplemented or amended Prospectus. If so directed by the Company,
such Holder will deliver to the Company (at the expense of the Company) all
copies in its possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Registrable Shares current at the
time of receipt of such notice.

5. BLACK-OUT PERIOD

     (a) Subject to the provisions of this Section 5, following the
effectiveness of a Registration Statement (and the filings with any
international, federal or state securities commissions), the Company may direct
the Holders, in accordance with Section 5(b), to suspend sales of the
Registrable Shares pursuant to a Registration Statement for such times as the
Company reasonably may determine is necessary and advisable (but in no event for
more than an aggregate of ninety (90) days in any consecutive twelve (l2)-month
period commencing on the Closing Date or more than sixty (60) days in any
consecutive 90-day period except as a result of a review of any post-effective
amendment by the Commission prior to declaring any post-effective amendment to
the Registration Statement effective, provided the Company has used all
commercially reasonable efforts to cause such post effective amendment to be
declared effective), if any of the following events shall occur: (i) the
representative of the underwriters of an Underwritten Offering of primary shares
by the Company has advised the Company that the


                                       14

<PAGE>

sale of Registrable Shares pursuant to the Registration Statement would have a
material adverse effect on the Company's initial public offering; (ii) the
majority of the members of the Board of Directors of the Company shall have
determined in good faith that the offer or sale of any Registrable Shares would
materially impede, delay or interfere with any proposed financing, offer or sale
of securities, acquisition, merger, tender-offer, business combination,
corporate reorganization or other significant transaction involving the Company;
(iii) after the advice of counsel, the majority of the members of the Board of
Directors of the Company shall determine, in good faith, that the offer or sale
of Registrable Shares pursuant to the Registration Statement would require
disclosure of non-public material information not otherwise required to be
disclosed under applicable law and (x) the Company has a bona fide business
purposes for preserving the confidentiality of such information and (y) the
nondisclosure of such information would cause the Registration Statement to fail
to comply with Commission requirements; or (iv) after the advice of counsel, the
majority of the members of the Board of Directors of the Company shall have
determined in good faith, that the Company is required by law, rule or
regulation or Commission published release or interpretation to supplement the
Registration Statement or file a post-effective amendment to the Registration
Statement in order to incorporate information into the Registration Statement
for the purpose of (1) including in the Registration Statement any prospectus
required under Section 10(a)(3) of the Securities Act; (2) reflecting in the
prospectus included in the Registration Statement any facts or events arising
after the effective date of the Registration Statement (or of the most-recent
post-effective amendment) that, individually or in the aggregate, represents a
fundamental change in the information set forth therein; or (3) including in the
prospectus included in the Registration Statement any material information with
respect to the plan of distribution not disclosed in the Registration Statement
or any material change to such information. Upon the occurrence of any such
suspension, the Company shall use all commercially reasonable efforts to cause
the Registration Statement to become effective or to promptly amend or
supplement the Registration Statement on a post-effective basis or to take such
action as is necessary to make resumed use of the Registration Statement
compatible with the Company's best interests, as applicable, so as to permit the
Holders to resume sales of the Registrable Shares as soon as possible.

     (b) In the case of an event that causes the Company to suspend the use of a
Registration Statement (a "Suspension Event"), the Company shall give written
notice (a "Suspension Notice") to FBR and the Holders to suspend sales of the
Registrable Shares and such notice shall state generally the basis for the
notice and that such suspension shall continue only for so long as the
Suspension Event or its effect is continuing and the Company is using its best
efforts and taking all reasonable steps to terminate suspension of the use of
the Registration Statement as promptly as possible. No Holder shall effect any
sales of the Registrable Shares pursuant to such Registration Statement (or such
filings) at any time after it has received a Suspension Notice from the Company
and prior to receipt of an End of Suspension Notice (as defined below). If so
directed by the Company, each Holder will deliver to the Company (at the expense
of the Company) all copies other than permanent file copies then in such
Holder's possession of the Prospectus covering the Registrable Shares at the
time of receipt of the Suspension Notice. The Holders may recommence effecting
sales of the Registrable Shares pursuant to the Registration Statement (or such
filings) following further notice to such effect (an "End of Suspension Notice")
from the Company, which End of Suspension Notice shall be given by the Company
to the Holders and FBR in the manner described above promptly following the
conclusion of any Suspension Event and its effect.


                                       15

<PAGE>

     (c) Notwithstanding any provision herein to the contrary, if the Company
shall give a Suspension Notice pursuant to this Section 5, the Company agrees
that it shall extend the period of time during which the applicable Registration
Statement shall be maintained effective pursuant to this Agreement by the number
of days during the period from the date of receipt by the Holders of the
Suspension Notice to and including the date of receipt by the Holders of the End
of Suspension Notice and copies of the supplemented or amended Prospectus
necessary to resume sales.

6. INDEMNIFICATION AND CONTRIBUTION

     (a) The Company agrees to indemnify and hold harmless (i) each Holder of
Registrable Shares and any underwriter (as determined in the Securities Act) for
such Holder (including FBR, if applicable), (ii) each Person, if any, who
controls (within the meaning of Section 15 of the Securities Act or Section
20(a) of the Exchange Act), any such Person described in clause (i) (any of the
Persons referred to in this clause (ii) being hereinafter referred to as a
"Controlling Person"), and (iii) the respective officers, directors, partners,
employees, representatives and agents of any such Person or any Controlling
Person (any Person referred to in clause (i), (ii) or (iii) may hereinafter be
referred to as a "Purchaser Indemnitee"), to the fullest extent lawful, from and
against any and all losses, claims, damages, judgments, actions, out-of-pocket
expenses, and other liabilities (the "Liabilities"), including without
limitation and as incurred, reimbursement of all reasonable costs of
investigating, preparing, pursuing or defending any claim or action, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, including the reasonable fees and expenses of counsel to any
Purchaser Indemnitee, joint or several, directly or indirectly related to, based
upon, arising out of or in connection with any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement or
Prospectus (as amended or supplemented if the Company shall have furnished to
such Purchaser Indemnitee any amendments or supplements thereto), or any
preliminary Prospectus or any other document used to sell the Shares, or any
omission or alleged omission to state therein 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, except insofar as such
Liabilities arise out of or are based upon (i) any untrue statement or omission
or alleged untrue statement or omission made in reliance upon and in conformity
with information relating to any Purchaser Indemnitee furnished to the Company
or any underwriter in writing by such Purchaser Indemnitee expressly for use
therein, or (ii) any untrue statement contained in or omission from a
preliminary Prospectus if a copy of the Prospectus (as then amended or
supplemented, if the Company shall have furnished to or on behalf of the Holder
participating in the distribution relating to the relevant Registration
Statement any amendments or supplements thereto) was not sent or given by or on
behalf of such Holder to the Person asserting any such Liabilities who purchased
Shares, if such Prospectus (or Prospectus as amended or supplemented) is
required by law to be sent or given at or prior to the written confirmation of
the sale of such Shares to such Person and the untrue statement contained in or
omission from such preliminary Prospectus was corrected in the Prospectus (or
the Prospectus as amended or supplemented). The Company shall notify the Holders
promptly of the institution, threat or assertion of any claim, proceeding
(including any governmental investigation), or litigation of which it shall have
become aware in connection with the matters addressed by this Agreement which
involves the Company or a Purchaser Indemnitee. The


                                       16

<PAGE>

indemnity provided for herein shall remain in full force and effect regardless
of any investigation made by or on behalf of any Purchaser Indemnitee.

     (b) In connection with any Registration Statement in which a Holder of
Registrable Shares is participating, such Holder agrees, severally and not
jointly, to indemnify and hold harmless the Company, each Person who controls
the Company within the meaning of Section 15 of the Securities Act or Section
20(a) of the Exchange Act and the respective partners, directors, officers,
members, representatives, employees and agents of such Person or Controlling
Person to the same extent as the foregoing indemnity from the Company to each
Purchaser Indemnitee, but only with reference to untrue statements or omissions
or alleged untrue statements or omissions made in reliance upon and in strict
conformity with information relating to such Purchaser Indemnitee furnished to
the Company in writing by such Purchaser Indemnitee expressly for use in any
Registration Statement or Prospectus, any amendment or supplement thereto or any
preliminary Prospectus. The liability of any Purchaser Indemnitee pursuant to
this paragraph shall in no event exceed the net proceeds received by such
Purchaser Indemnitee from sales of Registrable Shares giving rise to such
obligations.

     (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnity may be sought pursuant to paragraph (a)
or (b) above, such Person (the "Indemnified Party"), shall promptly notify the
Person against whom such indemnity may be sought (the "Indemnifying Party"), in
writing of the commencement thereof (but the failure to so notify an
Indemnifying Party shall not relieve it from any liability which it may have
under this Section 6, except to the extent the Indemnifying Party is materially
prejudiced by the failure to give notice), and the Indemnifying Party, upon
request of the Indemnified Party, shall retain counsel reasonably satisfactory
to the Indemnified Party to represent the Indemnified Party and any others the
Indemnifying Party may reasonably designate in such proceeding and shall pay the
reasonable fees and expenses actually incurred by such counsel related to such
proceeding. Notwithstanding the foregoing, in any such proceeding, any
Indemnified Party shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party,
unless (i) the Indemnifying Party and the Indemnified Party shall have mutually
agreed in writing to the contrary, (ii) the Indemnifying Party failed within a
reasonable time after notice of commencement of the action to assume the defense
and employ counsel reasonably satisfactory to the Indemnified Party, (iii) the
Indemnifying Party and its counsel do not actively and vigorously pursue the
defense of such action or (iv) the named parties to any such action (including
any impleaded parties), include both such Indemnified Party and the Indemnifying
Party, or any Affiliate of the Indemnifying Party, and such Indemnified Party
shall have been reasonably advised by counsel that, either (x) there may be one
or more legal defenses available to it which are different from or additional to
those available to the Indemnifying Party or such Affiliate of the Indemnifying
Party or (y) a conflict may exist between such Indemnified Party and the
Indemnifying Party or such Affiliate of the Indemnifying Party (in which case
the Indemnifying Party shall not have the right to assume nor direct the defense
of such action on behalf of such Indemnified Party, it being understood,
however, that the Indemnifying Party shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel), for all such Indemnified Parties,


                                       17

<PAGE>

which firm shall be designated in writing by those Indemnified Parties who sold
a majority of the Registrable Shares sold by all such Indemnified Parties and
any such separate firm for the Company, the directors, the officers and such
control Persons of the Company as shall be designated in writing by the
Company). The Indemnifying Party shall not be liable for any settlement of any
proceeding effected without its written consent, which consent shall not be
unreasonably withheld, but if settled with such consent or if there is a final
nonappealable judgment for the plaintiff, the Indemnifying Party agrees to
indemnify any Indemnified Party from and against any loss or liability by reason
of such settlement or judgment. No Indemnifying Party shall, without the prior
written consent of the Indemnified Party, effect any settlement of any pending
or threatened proceeding in respect of which any Indemnified Party is or could
have been a party and indemnity could have been sought hereunder by such
Indemnified 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.

     (d) If the indemnification provided for in paragraphs (a) and (b) of this
Section 6 is for any reason held to be unavailable to an Indemnified Party in
respect of any Liabilities referred to therein (other than by reason of the
exceptions provided therein) or is insufficient to hold harmless a party
indemnified thereunder, then each Indemnifying Party under such paragraphs, in
lieu of indemnifying such Indemnified Party thereunder, shall contribute to the
amount paid or payable by such Indemnified Party as a result of such Liabilities
(i) in such proportion as is appropriate to reflect the relative benefits of the
Indemnified Party on the one hand and the Indemnifying Party(ies) on the other
in connection with the statements or omissions that resulted in such
Liabilities, or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Indemnifying Party(ies) and the Indemnified Party, as well as any
other relevant equitable considerations. The relative fault of the Company on
the one hand and any Purchaser Indemnitees on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or by such Purchaser Indemnitees
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

     (e) The parties agree that it would not be just and equitable if
contribution pursuant to this Section 6 were determined by pro rata allocation
(even if such Indemnified Parties were treated as one entity for such purpose),
or by any other method of allocation that does not take account of the equitable
considerations referred to in paragraph 6(d) above. The amount paid or payable
by an Indemnified Party as a result of any Liabilities referred to paragraph
6(d) shall be deemed to include, subject to the limitations set forth above, any
reasonable legal or other expenses actually incurred by such Indemnified Party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 6, in no event shall a Purchaser
Indemnitee be required to contribute any amount in excess of the amount by which
proceeds received by such Purchaser Indemnitee from sales of Registrable Shares
exceeds the amount of any damages that such Purchaser Indemnitee has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. For purposes of this Section 6, each Person, if
any, who controls (within the meaning of Section 15 of the Act or Section 20(a)
of the Exchange Act) FBR or a Holder of Registrable Shares shall


                                       18

<PAGE>

have the same rights to contribution as FBR or such Holder, as the case may be,
and each Person, if any, who controls (within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange Act) the Company, and each officer,
director, partner, employee, representative, agent or manager of the Company
shall have the same rights to contribution as the Company. Any party entitled to
contribution will, promptly after receipt of notice of commencement of any
action, suit or proceeding against such party in respect of which a claim for
contribution may be made against another party or parties, notify each party or
parties from whom contribution may be sought, but the omission to so notify such
party or parties shall not relieve the party or parties from whom contribution
may be sought from any obligation it or they may have under this Section 6 or
otherwise, except to the extent that any party is materially prejudiced by the
failure to give notice. No Person guilty of fraudulent misrepresentation (within
the meaning of Section 1l(f) of the Securities Act), shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

     (f) The indemnity and contribution agreements contained in this Section 6
will be in addition to any liability which the Indemnifying Parties may
otherwise have to the Indemnified Parties referred to above. The Purchaser
Indemnitee's obligations to contribute pursuant to this Section 6 are several in
proportion to the respective number of Shares sold by each of the Purchaser
Indemnitees hereunder and not joint.

7. MARKET STAND-OFF AGREEMENT

     Each Holder hereby agrees that it shall not, to the extent requested by the
Company or an underwriter of securities of the Company, directly or indirectly
sell, offer to sell (including without limitation any short sale), grant any
option or otherwise transfer or dispose of any Registrable Shares or other
shares of Common Stock of the Company or any securities convertible into or
exchangeable or exercisable for shares of Common Stock of the Company then owned
by such Holder (other than to donees or partners of the Holder who agree to be
similarly bound) for a period of sixty (60) days following the effective date of
an IPO Registration Statement of the Company filed under the Securities Act;
provided, however, that:

     (a) the restrictions above shall not apply to Registrable Shares sold
pursuant to the IPO Registration Statement;

     (b) all executive officers and directors of the Company then holding shares
of Common Stock of the Company or securities convertible into or exchangeable or
exercisable for shares of Common Stock of the Company enter into similar
agreements;

     (c) the Holders shall be allowed any concession or proportionate release
allowed to any executive officer or director that entered into similar
agreements (with such proportion being determined by dividing the number of
shares being released with respect to such officer or director by the total
number of issued and outstanding shares held by such officer or director);
provided, that nothing in this Section 7(c) shall be construed as a right to
proportionate release for the executive officers and directors of the Company
upon the expiration of the 60-day period applicable to all Holders other than
the executive officers and directors of the Company;


                                       19

     (d) this Section 7 shall not be applicable if a Shelf Registration
Statement of the Company filed under the Securities Act has been declared
effective prior to the filing of an IPO Registration Statement.

     In order to enforce the foregoing covenant, the Company shall have the
right to place restrictive legends on the certificates representing the
securities subject to this Section 7 and to impose stop transfer instructions
with respect to the Registrable Shares and such other securities of each Holder
(and the securities of every other Person subject to the foregoing restriction)
until the end of such period.

8. TERMINATION OF THE COMPANY'S OBLIGATION

     The Company shall have no obligation pursuant to this Agreement at such
time as no Registrable Securities are outstanding; provided that the Company's
obligations under Sections 3, 6 and 10 of the Agreement shall remain in full
force and effect.

9. LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS

     From and after the date of this Agreement, the Company shall not, without
the prior written consent of Holders beneficially owning not less than a
majority of the then outstanding Registrable Shares (provided, however, that for
purposes of this Section 9, Registrable Shares that are owned, directly or
indirectly, by an Affiliate of the Company shall not be deemed to be
outstanding), enter into any agreement with any holder or prospective holder of
any securities of the Company that would allow such holder or prospective holder
(a) to include such securities in any Registration Statement (other than an IPO
Registration Statement) filed pursuant to the terms hereof, unless under the
terms of such agreement, such holder or prospective holder may include such
securities in any such registration only to the extent that the inclusion of his
securities will not reduce the amount of Registrable Shares of the Holders that
is included, or (b) to have his securities registered on a registration
statement that could be declared effective prior to the earlier of (x) the date
that is one hundred eighty (180) days after the effective date of any
Registration Statement filed pursuant to this Agreement and (y) the one year
anniversary of the date of this Agreement.

10. MISCELLANEOUS

     (a) Remedies. In the event of a breach by the Company of any of its
obligations under this Agreement, each Holder, in addition to being entitled to
exercise all rights provided herein or, in the case of FBR, in the
Purchase/Placement Agreement, or granted by law, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement.
Subject to Section 6, the Company agrees that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by it of any
of the provisions of this Agreement and hereby further agree that, in the event
of any action for specific performance in respect of such breach, it shall waive
the defense that a remedy at law would be adequate.

     (b) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to or departures from the provisions hereof may not be
given, without the written


                                       20

<PAGE>

consent of the Company and Holders beneficially owning not less than a majority
of the then outstanding Registrable Shares; provided, however, that for purposes
of this Section 10(b), Registrable Shares that are owned, directly or
indirectly, by an Affiliate of the Company shall not be deemed to be
outstanding. No amendment shall be deemed effective unless it applies uniformly
to all Holders. Notwithstanding the foregoing, a waiver or consent to or
departure from the provisions hereof with respect to a matter that relates
exclusively to the rights of a Holder whose shares of common stock are being
sold pursuant to a Registration Statement and that does not directly or
indirectly affect, impair, limit or compromise the rights of other Holders may
be given by such Holder; provided that the provisions of this sentence may not
be amended, modified or supplemented except in accordance with the provisions of
the immediately preceding sentence.

     (c) Notices. All notices and other communications, provided for or
permitted hereunder shall be made in writing by delivered by facsimile (with

     (d) Successors and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors and assigns of each of the parties hereto,
including, without limitation and without the need for an express assignment or
assumption, subsequent Holders. The Company agrees that the Holders shall be
third party beneficiaries to the agreements made hereunder by FBR and the
Company, and each Holder shall have the right to enforce such agreements
directly to the extent it deems such enforcement necessary or advisable to
protect its rights hereunder; provided, however that such Holder fulfills all
of its obligations hereunder.

     (e) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken

LAW. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION
OF ANY STATE COURT IN THE STATE OF NEW YORK OR ANY FEDERAL COURT SITTING IN NEW
YORK IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT, AND IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS
PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID

HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING
BROUGHT IN ANY SUCH COURT AND ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING
BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

     (h) Severability. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall in
no way be affected, impaired or invalidated, and the parties hereto shall use
their commercially reasonable efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties hereto that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

     (i) Entire Agreement. This Agreement, together with the Purchase/Placement
Agreement, is intended by the parties hereto as a final expression of their
agreement, and is intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto in respect of the subject
matter contained herein and therein.

     (j) Registrable Shares Held by the Company or its Affiliates. Whenever the
consent or approval of Holders of a specified percentage of Registrable Shares
is required hereunder, Registrable Shares held by the Company or its Affiliates
shall not be counted in determining whether such consent or approval was given
by the Holders of such required percentage.

     (k) Adjustment for Stock Splits, etc. Wherever in this Agreement there is a
reference to a specific number of shares with respect to any Registrable Shares,
then upon the occurrence of any subdivision, combination, or stock dividend of
such shares, the specific number of shares with respect to any Registrable
Shares so referenced in this Agreement shall automatically be proportionally
adjusted to reflect the effect on the outstanding shares of such class or series
of stock by such subdivision, combination, or stock dividend.

     (l) Survival. This Agreement is intended to survive the consummation of the
transactions contemplated by the Purchase/Placement Agreement. The
indemnification and contribution obligations under Section 6 of this Agreement
shall survive the termination of the Company's obligations under Section 2 of
this Agreement.

available remedy.
