MANAGEMENT OF THE COMPANY;

ACTIVITIES OF THE PARTIES

3.1 Board of Directors.

(a) Generally. The Board of Directors of the Company shall manage the operation
and affairs of the Company in accordance with the Company’s certificate of
incorporation and bylaws and, in accordance therewith, shall select, appoint and

accordance with the provisions contained herein and in the Company’s certificate
of incorporation and bylaws. Notwithstanding anything to the contrary contained
herein:

 

  (i) the Observer rights in Section 3.1(b) below shall terminate and be of no
further force and effect on the earlier of (i) the closing date of the Qualified
IPO or (ii) the date Chesapeake ceases to beneficially own 5% or more of the
Company’s outstanding Common Stock;

 

  (ii) the rights set forth in Sections 3.2 and 3.3 regarding the election of
directors shall terminate and be of no further force or effect effective as of

reports and other communications sent to directors, at

 

9

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

the same time they are transmitted to directors. The Observer may be excluded
from any meeting or portion thereof and need not be provided such materials if a
majority of the Board of Directors reasonably believes that the Observer’s
attendance at such meeting or access to such information would: (i) adversely
affect attorney-client privilege between the Company and its counsel;
(ii) represent confidential or proprietary business information that could be
misused by Chesapeake; or (iii) involve a conflict of interest between the
Company and Chesapeake. Chesapeake agrees and acknowledges that it and the

the Company’s. The Information may or may not be known by the Observer. The
Company agrees that Chesapeake and the Observer shall have no duty to disclose
any Information to the Company or permit the Company to participate in any
investments based on any Information, or to otherwise take advantage of any
opportunity that may be of interest to the Company if it were aware of such
Information, and hereby waives, to the extent permitted by law, any claim based
on the corporate opportunity doctrine or that would require Chesapeake or the
Observer to disclose any such Information to the Company or offer any
opportunity relating thereto to the Company. Any one of the individuals named on
Schedule 3.2 may act as Chesapeake’s Observer. From time to time, Chesapeake
may, upon written notice to and approval by the Company, propose an amendment to
Schedule 3.2 to replace any of the individuals named on Schedule 3.2 with
different individuals who may act as Observer. The right of Chesapeake to an
Observer shall be suspended during the time period in which Chesapeake has
exercised its right to direct the election and appointment of a director under
Section 3.4 hereof and such directors hold office.

Qualified IPO and as long as Fischer, Altoma and their Permitted Transferees own

the Company, the Parties to this Agreement (and any successor(s) in interest),

directors designated by Fischer in accordance with this Section 3.2 promptly
upon request, and in the event such request is made, until such designees have

interest), shall take or cause to be taken all action within their power,

to maintain the same percentage ownership of outstanding securities of such
class of Capital Stock of the Company as it owned immediately prior to such

provided, however, that if, in connection with any proposed transaction or
transactions giving rise to rights hereunder (including pursuant to a Subsequent

were available in the Parties pursuant to their rights hereunder, no Party shall
have any preemptive rights under this Section and the proposed transaction or
transactions shall be consummated without any exercise of preemptive rights
hereunder. In the event of a situation described in the preceding sentence in

proposed transaction or transactions, the Company shall provide notice (the
“Subsequent Notice”) of such fact within five (5) Business Days following the
receipt of all of the notices concerning such elections from the Parties
possessing such preemptive rights. Each Party possessing the right to purchase
the additional shares of Capital Stock upon which the preemptive rights were not
exercised shall respond to this Subsequent Notice by sending a response notice
with respect thereto within five (5) Business Days after delivery of the
Subsequent Notice. Failure of any Party to respond to such Subsequent Notice
with a notice stating the election of such Party to purchase such additional
shares of Capital Stock shall be deemed to be an election not to purchase such
shares of Capital Stock and the proposed transaction or transactions shall be
consummated without any exercise of preemptive rights hereunder.

(in no event later than one hundred twenty (120) days after the end of such

date (or similar statements if such statements change as the result of changes
in GAAP), in each case setting forth in comparative form the corresponding
figures for the preceding fiscal quarter and for the fiscal quarter of the prior
fiscal year corresponding to the fiscal quarter just completed. The filing of
the financial statements with the SEC shall satisfy the foregoing obligations.

shall not vote for the approval of (i) any merger, consolidation or conversion,
(ii) an increase in authorized number of the Company’s shares, or the amendment

ARTICLE 4

4.1 Transfer of Capital Stock.

(a) No Party other than the Company (which shall be subject to the preemptive
rights set forth in Section 3.7) may Transfer any shares of Capital Stock of the
Company, except as contemplated by Sections 4.2, 4.3, 4.7, 4.8 or 4.9 hereof or
pursuant to an offering of equity securities registered under the Securities Act
by the Company. The terms and provisions of this Article 4 shall terminate and
be of no further force and effect with respect to Capital Stock owned by any of
the Parties at such time as: (i) prior to a Qualified IPO, the percentage
ownership of the Fischer Parties and their Affiliates of the outstanding Common
Stock of the Company is less than 25% of their percentage ownership of
outstanding Common Stock as of the date hereof (the “Fischer Initial Position”)
or (ii) after a Qualified IPO, (x) with respect to Section 4.8 and Section 4.9,
the closing date of the Qualified IPO, and (y) with respect to all other
Sections under Article 4, the date that the “lock-up” period, as specified in
lock-up letters required under Section 5.12 or otherwise (the “Contractual
Lock-Up Period”), relating to the Qualified IPO terminates (the “Lock-Up
Expiration Date”).

(b) In the event any of the Holders is given the opportunity to participate in a
Piggyback Registration and (i) such Holder declines to participate in the
Piggyback Registration and (ii) the sale of securities in the offering related
to such declined Piggyback Registration is actually completed, then such Holder
may, notwithstanding the provisions of this Article 4 (but

 

13

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

subject to its obligations under any lock-up letter to which such Holder is
subject pursuant to Section 5.12 or otherwise), Transfer a number of shares
equal to the number of shares it would have been able to sell in connection with
the applicable Piggyback Registration, subject to Sections 4.6 and 4.9 of this
Agreement and provided that the purchaser(s) of such shares execute and become
parties to this Agreement.

(c) Notwithstanding the terms of this Section 4.1, after a Qualified IPO,
Fischer, in its sole and absolute discretion, may permit any of the other
Holders to Transfer shares of Capital Stock of the Company without the consent
of the other Parties hereto.

4.2 Tag-Along Rights.

(a) If Fischer, or any of its Permitted Transferees who have acquired Common
Stock without Fischer making a Tag-Along Offer under this Section 4.2 (Fischer
and any such other Fischer Parties being referred to herein as a “Tag-Along
Seller”), proposes to sell more than 25% of the outstanding shares of Common
Stock at such time for value in a Bona Fide Offer to a Third Party in one
transaction or a series of related transactions (such transaction, the
“Tag-Along Sale”), but excluding (i) a sale pursuant to a Qualified IPO or other
public offering, (ii) any sale in which all of the Parties agree to participate,
and (iii) a sale made pursuant to a ROFO Notice in accordance with Section 4.9,
then such Tag-Along Seller shall offer (the “Tag-Along Offer”) to each
stockholder Party the right to include in the proposed sale a number of shares
of Common Stock designated by any of the Parties, not to exceed, in respect of
any such Party, that number of shares of Common Stock determined by application
of the following formula: (A) the number of all shares of Common Stock proposed
to be sold by the Tag-Along Seller and such other Parties in the Tag-Along Sale
multiplied by (B)(i) the number of outstanding shares of Common Stock held by
such Party divided by (ii) the sum of the number of outstanding shares of Common
Stock held by all Tag-Along Sellers and other Parties in the Tag-Along Sale.

(b) The Tag-Along Seller shall give written notice to each Party of the
Tag-Along Offer (the “Tag-Along Seller’s Notice”) not less than 30 days nor more
than 270 days prior to the consummation of the proposed sale. The Tag-Along
Seller’s Notice may be issued concurrent with a ROFO Notice pursuant to
Section 4.9. The Tag-Along Seller’s Notice shall specify the proposed
transferee, the number of shares of Common Stock to be sold to such transferee,
the amount and type of consideration to be received therefor, and the place and
date on which the sale is to be consummated. Each Party who wishes to include
shares of Common Stock in the Tag-Along Sale in accordance with the terms of
this Section 4.2 shall so notify the Tag-Along Seller not more than 15 days
after the date of receipt of the Tag-Along Seller’s Notice. The Tag-Along Offer
shall be conditioned upon the Tag-Along Seller’s sale of shares of Common Stock
pursuant to the transactions contemplated in the Tag-Along Seller’s Notice with
the transferee named therein. If any Party accepts the Tag-Along Offer, the
Tag-Along Seller shall reduce to the extent necessary the number of shares of
Common Stock it otherwise would have sold in the proposed sale so as to permit
other Parties who have accepted the Tag-Along Offer to sell the number of shares
of Common Stock that they are entitled to sell under this Section 4.2, and the
Tag-Along Seller and such other Party or Parties shall sell the number of shares
of Common Stock specified in the Tag-Along Offer to the proposed transferee in
accordance with the terms of such sale set forth in the Tag-Along Seller’s
Notice.

 

14

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

(c) For purposes of this Section 4.2, the number of shares of Common Stock shall
be deemed to include the shares of Common Stock represented by Common Stock
Equivalents. Notwithstanding the foregoing, no Common Stock Equivalents shall
receive the benefits of this Section 4.2 prior to the time such Common Stock
Equivalents are exercisable for or convertible or exchangeable into shares of
Common Stock and, in order to obtain the benefits of this Section 4.2, any such
Common Stock Equivalents in the form of options, warrants or other securities
convertible or exchangeable into or exercisable for shares of Common Stock must
be exercised or canceled prior to or simultaneously with the consummation of the
sale pursuant to this Section 4.2.

(d) The acceptance of a Tag-Along Offer shall be binding and irrevocable upon
the Party accepting the Tag-Along Offer unless (i) there is a material adverse
change in the material terms of the Tag-Along Sale or (ii) if otherwise mutually
agreed in writing by the Tag-Along Sellers and such Party. By delivering and
accepting a Tag-Along Offer, each Party accepting the Tag-Along Offer agrees to
execute and deliver such agreements and instruments as a Tag-Along Seller and
Third Party might reasonably request to effect a proposed sale.

(e) Except as otherwise provided in this Section 4.2, the Common Stock subject
to a Tag-Along Offer will be included in a proposed sale and in any agreements
with the Third Party on the same terms and subject to the same conditions
applicable to the Common Stock of the Tag-Along Seller subject to the proposed
sale. Such terms and conditions shall include, without limitation: the sales
price; the payment of fees, commissions and expenses; the provision of
representations, warranties and indemnifications; provided that any
indemnification provided by each requesting Party shall (except with respect to
legal title to the relevant securities) be pro rata in proportion with the total
consideration to be received by the requesting Party as the case may be,
relative to the total consideration to be received by the Tag-Along Seller and
other requesting Parties.

(f) The terms, rights and obligations under this Section 4.2 shall terminate and
be of no further force and effect on such date that the number of outstanding
shares of Common Stock held by the Parties to this Agreement is less than 50% of
the then outstanding shares of Common Stock of the Company.

4.3 Drag-Along Rights.

(a) Notwithstanding any other provision in this Article 4, but specifically
subject to the right of first offer in Section 4.9, if Fischer or its Permitted
Transferees or other Affiliates (such Fischer Parties and/or their Affiliates
being referred to in this Section 4.3 as the “Seller”) and any other Parties
propose to sell in any single or series of related transactions shares of Common
Stock and Common Stock Equivalents representing all of the Common Stock and
Common Stock Equivalents owned by the Seller and such other Parties and such
shares of Common Stock constitute more than 50% of the outstanding shares of
Common Stock (the “Sale Stock”) at such time to a Third Party pursuant to a Bona
Fide Offer, then the Seller shall have the right, subject to the provisions of
this Section 4.3, to require all other Parties that are not the Seller
(collectively, the “Co-Sellers”) to include in such sale (a “Required Sale”)
all, but not less than all of such Co-Seller’s shares of Common Stock and Common
Stock Equivalents (the “Co-Sellers’ Stock”), by delivering notice (the “Required
Sale Notice”) to such other Parties.

 

15

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

(b) The Required Sale Notice shall set forth: (i) the date of such notice (the
“Notice Date”); (ii) the name and address of the Third Party; (iii) the proposed
amount and type of consideration (subject to Chesapeake’s right to require
payment to it in cash) to be paid per share of Common Stock for the Sale Stock
(the “Sale Price”), and a description in reasonable detail of the terms and
conditions of payment offered by the Third Party, together with written
proposals or agreements, if any, with respect thereto; and (iv) the proposed
date of the Required Sale (the “Required Sale Date”), which shall be not less
than 30 nor more than 180 days after the Notice Date.

(c) The Co-Sellers shall cooperate in good faith with Seller in connection with
consummating the Required Sale (including, without limitation, the giving of
consents and the voting of any shares of Common Stock of the Company held by the
Co-Sellers to approve such Required Sale). On the Required Sale Date, each of
the Co-Sellers shall deliver, free and clear of all liens, claims or
encumbrances, and on the same terms and conditions applicable to the Seller’s
sale of the Sale Stock (subject to Chesapeake’s right to require payment to it
in cash), a certificate or certificates and/or other instrument or instruments
for all of its shares of Common Stock and Common Stock Equivalents, duly
endorsed and in proper form for transfer, with the signature guaranteed, to such
Third Party in the manner and at the address indicated in the Required Sale
Notice and Seller shall cause the Third Party to pay each Co-Seller’s share of
the purchase price to such Co-Seller. Notwithstanding anything to the contrary
in this Section 4.3, all consideration to be paid for Common Stock held by
Chesapeake or its Permitted Transferees controlled by Chesapeake shall be in the
form of cash or immediately available cash equivalent funds unless otherwise
agreed to in writing by Chesapeake.

(d) In the event of any Required Sale, all Co-Sellers that hold Common Stock
Equivalents in the form of options, warrants or other securities convertible or
exchangeable into or exercisable for shares of Common Stock must exercise or
cancel all such options, warrants or conversion or other rights prior to or
simultaneously with the consummation of the Required Sale.

(e) The terms, rights and obligations under this Section 4.3 shall terminate and
be of no further force and effect on such date that the number of outstanding
shares of Common Stock held by the Parties to this Agreement is less than 50% of
the then outstanding shares of Common Stock of the Company.

4.4 Prohibited Transfers. Any purported Transfer of shares of Common Stock or
Common Stock Equivalents by a Party that is not permitted by the provisions of
Article 4, or which is in violation of such provisions, shall be void and of no
force and effect whatsoever.

4.5 Certain Events Not Deemed Transfers. Except as contemplated by Section 4.3
hereof, in no event shall any of the following constitute a transfer of shares
of Common Stock for purposes of Sections 4.1, 4.2, or 4.3 or be subject to the
terms hereof: (i) an exchange, reclassification or other conversion of shares of
Common Stock into any cash, securities or other property pursuant to a merger,
consolidation or recapitalization of the Company or any Subsidiary with, or a
sale or transfer by the Company or any Subsidiary of all or substantially all
its assets to, any Person; or (ii) an exercise or conversion of Common Stock
Equivalents into shares of Common Stock in accordance with the terms thereof.

 

16

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

4.6 Transfers Subject to Compliance with Securities Act and Other Applicable
Law. No shares of Common Stock may be Transferred by a Party (other than
pursuant to an effective registration statement under the Securities Act) unless
such Party first delivers to the Company an opinion of counsel, which opinion
and counsel shall be reasonably satisfactory to the Company, to the effect that
such Transfer is not required to be registered under the Securities Act and any
other applicable law.

4.7 Permitted Transferees.

(a) Notwithstanding anything in this Agreement to the contrary (other than
Section 4.6), any of Fischer, Altoma or Chesapeake, or any Affiliate of any of
Fischer, Altoma or Chesapeake, or any Permitted Transferee thereof may, without
the consent of the Company or any of the Parties and without compliance with
Sections 4.1, 4.2, or 4.3, at any time Transfer any or all of its shares of
Common Stock and Common Stock Equivalents to one or more Permitted Transferees,
provided that (i) the Transfer to such Person is not in violation of applicable
U.S. federal or state securities laws, or other similar laws, and (ii) such
Person(s), by accepting such shares of Common Stock or Common Stock Equivalents,
shall be deemed to have agreed to be bound by the terms of this Agreement on the
same terms as the Transferring Party generally.

(b) Notwithstanding anything in this Agreement to the contrary (other than
Section 4.6), any Other Party or any Other Permitted Transferees may, without
the consent of the Company or any of the Parties and without compliance with
Sections 4.1, 4.2, or 4.3, at any time Transfer any or all of its shares of
Common Stock and Common Stock Equivalents to one or more Other Permitted
Transferees, provided that (i) the Transfer to such Person is not in violation
of applicable U.S. federal or state securities laws, or other similar laws,
(ii) such Person(s) shall execute and deliver to the Company a written
acknowledgement, in form and substance satisfactory to the Company, stating that
such Person(s) agrees to be bound by the terms of this Agreement (on the same
terms as such Other Party), and (iii) if any such Other Permitted Transferee
shall cease to qualify as an Other Permitted Transferee after such Transfer, the
Common Stock and Common Stock Equivalents of such Other Permitted Transferee
(A) shall continue to be subject to the terms and conditions of this Agreement
and the acceptance of such shares of Common Stock or Common Stock Equivalents by
such Person(s) shall be deemed as agreement to be so bound and (B) shall be
deemed to be owned by the Other Party that originally Transferred such shares
pursuant to this Section 4.7(b) for the purpose of calculating such Other
Party’s percentage ownership of Common Stock and/or Common Stock Equivalents as
such calculation may be required under the terms hereof.

(c) Notwithstanding anything in this Agreement to the contrary, upon the death

Party’s legatees, heirs or trustees of a testamentary trust, or to an executor
or administrator of the estate of such deceased Party incident to guardianship
or probate proceedings involving such estate shall not require the consent of
the Company or any of the Parties and shall not be subject to compliance with
Sections 4.1, 4.2, or 4.3 so long as (i) such heir shall have agreed in writing
to be bound by the terms of this Agreement and (ii) the Transfer to such heir is
not in violation of applicable law.

4.8 Listing of Shares; Altoma Shares.

(a) The Company agrees to use its commercially reasonable efforts to effect a
Qualified IPO prior to August 15, 2011.

 

17

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

(b) Each Altoma Party agrees that it shall include for sale in a registered
public offering a number of shares of Common Stock owned by it, which number
shall be designated by the Company in its sole discretion, up to the number of
shares of Common Stock to be sold concurrently by the Company, and in any event
with a value not greater than a maximum price to the public of $100 million
without the consent of the Altoma Parties. Other than the initial sale of shares
to Chesapeake pursuant to the Stock Purchase Agreement on the date of this
Agreement, each Altoma Party agrees that it shall not, without the consent of
Fischer, Transfer any of its shares of Common Stock to any Person until after
August 15, 2011, except through a Qualified IPO or with the consent of Fischer.

(c) After August 15, 2011, if the Common Stock of the Company is not listed on
an exchange or quoted on the Nasdaq National Market (or successor quotation
system or exchange), the Altoma Parties will have the right to Transfer to any
Person up to 60% of the shares of Common Stock owned by Altoma as of the date of
this Agreement pursuant to a Demand Request as set forth in
Section 5.1(b). However, notwithstanding Altoma’s right to a Demand Request set
forth in Section 5.1(b), prior to making such Demand Request, each of the Altoma
Parties agrees to offer its shares of Common Stock to be Transferred first to
the Company (who may elect to purchase any or all of the offered shares) for
purchase at Fair Market Value. Such offer by the Altoma Parties shall be in
writing and delivered to the Company, Fischer and Chesapeake. In the event the
Company elects to purchase less than all of Altoma’s shares of Common Stock
offered for Transfer, the remaining shares will be offered to Fischer and
Chesapeake on a 50/50 basis (who jointly may elect to purchase any or all of the
remaining offered shares) at Fair Market Value. Should either of Chesapeake or
Fischer elect to purchase less than their share of the Common Stock, the other
Party may elect to purchase more than their share up to the full balance of
offered shares remaining. The Company shall give written notice of its election
to purchase within 10 Business Days after receipt of the Altoma Parties offer
and Fischer and Chesapeake shall give written notice of their respective
elections by the earlier of the date 10 Business Days following the written
notice of election by the Company or 20 Business Days after the Altoma Parties’
original offer notice. In the event that the Company or Fischer exercise the
option to purchase the shares of Common Stock offered by the Altoma Parties
pursuant to this Section, each of the Altoma Parties agrees to finance up to 80%
of the purchase price payable by the Company or Fischer under substantially the
same terms and conditions as specified under Section 4.8(d) of this Agreement.
If the Company, Fischer and Chesapeake (i) provide notice of their intent not to
purchase, (ii) do not provide notice of their intent on or before 20 Business
Days after the date of receipt of the Altoma Parties original offer notice, or
(iii) fail to consummate a purchase of 100% of the shares offered by the Altoma
Parties in accordance with this Section 4.8(c), each of the Altoma Parties will
have the right, but not the obligation, for 120 days thereafter to: (1) Transfer
in an offering an amount not to exceed 60% of the shares of Common Stock owned
by it as of the date of this Agreement, less the amount of shares of Common
Stock Transferred to the Company and the Fischer Parties and Chesapeake pursuant
to the offering in this Section 4.8(c), to any person at a price equal to or
greater than the price at which it was offered to the Company, Fischer and
Chesapeake, or if such proposed sale price is less than that offered to the
Company, Fischer and Chesapeake, to provide the Company, Fischer and Chesapeake
a right to purchase the remaining shares at the lower price (by

 

18

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

complying again with the provisions of this Section 4.8(c)) before selling to
another person, or (2) effect a Demand Request in accordance with
Section 5.1(b), wherein each of the Altoma Parties agrees to offer for Transfer
in such registration statement all of the Common Stock which has not been
purchased pursuant to the offering in this Section 4.8(c)

(d) Any deferred portion of the purchase price pursuant to Section 4.8(c) above
payable by the Company or Fischer shall be evidenced by a promissory note
(“Promissory Note”) of the purchaser containing the following terms:

 

  (i) The Promissory Note shall bear interest at a fixed annual percentage rate
equal to the prime rate in effect by JP Morgan Chase Bank, N.A. on the date of
the Closing, may be prepaid at any time without penalty (any principal
prepayment shall be applied against the next maturing installment of principal),
shall provide for acceleration upon default, penalty interest, notice and
opportunity to cure upon default, and such other standard and customary terms as
the parties may agree. Except during any period in which the payments due under
the Promissory Note are tolled pursuant to Section 4.8(d)(iii), the Promissory
Note shall require equal semi-annual payments of principal plus accrued interest
over a term of four (4) years. The first such payment shall be due on the first
semi-annual anniversary of the Closing, and subsequent payments shall be due
consecutively on the subsequent semi-annual anniversaries of such date until the
fourth anniversary date at which time the unpaid balance of the Promissory Note
plus accrued interest shall be due and payable.

 

  (ii) The payment of the Promissory Note shall be secured at any time and from
time to time by that number of shares of Common Stock which equals one hundred
twenty five percent (125%) of the value of the unpaid principal amount remaining
under the Promissory Note at such time, not to exceed in any case more than the
original number of shares of Common Stock repurchased by the Company or
purchased by Fischer. For purposes of this Section 4.8(d)(ii), the value of the
shares of Common Stock held as security for the payment of the Promissory Note
shall be their Fair Market Value. At any time and from time to time, the
purchaser shall be entitled to a release of collateral to the extent that the
value of the Common Stock held by the holder of the Promissory Note exceeds the
unpaid principal amount remaining under the Promissory Note by more than
twenty-five percent (25%). Upon request by the purchaser for such release, the
holder of the Promissory Note shall exchange the stock certificate held as
collateral for a new stock certificate which reflects the release of shares
pursuant to this provision. In addition to the release of collateral described
above, the purchaser shall have the right, at any time and from time to time, to
substitute certificates of deposit issued by any state or national bank as
security for the purchaser’s obligations. The shares of Common Stock shall be
released in such amount so that the sum of the face value of the certificate of
deposit and one hundred twenty-five percent (125%) of the Fair Market Value of
the shares of Common Stock retained by the

 

19

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

       holder of the Promissory Note as of the end of the most recent fiscal
quarter for the Company for which financial statements are available equals the
unpaid principal amount remaining under the Promissory Note. So long as the
purchaser is not in default under the Promissory Note, the purchaser shall be
entitled to receive all interest paid on such substituted collateral.

 

  (iii) Any Promissory Note issued by the Company pursuant to this Section 4.8
shall provide that it is payable only out of “surplus” (as described in §154 of
the Delaware General Corporation Law), and shall further provide that, in the
event the Company shall not, at the time set for any payment, have available an
adequate surplus from which to make such payment, or any portion thereof, the
Company shall not make such payment, or such portion thereof, as the case may
be, and the date for payment, or such portion thereof, shall be tolled, with
interest accruing thereon until such surplus is available. The provisions of
this Agreement regarding the Company’s issuance and payment of Promissory Notes
only from surplus shall not be construed to impose on the Company any obligation
to create or generate any surplus of any type whatsoever. However, each year the
Company shall not declare any cash or stock dividend or voluntarily cause any
other charge to be made against surplus if the result thereof would be to cause
surplus to fall below the level needed to make any payment(s) on a Promissory
Note(s) which is payable during such year period or whose payment has been and
is, at the time of such dividend or charge, tolled pursuant to this
Section 4.8(d)(iii). In the event the payment of any installment on any
Promissory Note is tolled for a period of more than six (6) months, such
Promissory Note shall be in default, and the holder of such Promissory Note may,
upon notice of default by the holder and failure of the payee to make such
payment within 30 days after the date such notice is received, declare the
principal and all interest accrued thereon to be due and payable and may
foreclose on any shares of Common Stock or other collateral which shall be the
security therefor.

4.9 Right of First Offer.

(a) Subject to and excluding other permitted transfers set forth in
Section 4.1(a) for any transfers made pursuant to an offering of equity
securities registered under the Securities Act, Section 4.3 pursuant to a sale
in which the Sellers are exercising such drag-along rights, Section 4.5 and
Section 4.7, in the event Fischer or Chesapeake or any Permitted Transferee who
has acquired shares of Common Stock from such party (the “ROFO Seller”) desires
to Transfer shares of Common Stock owned by it to any Person other than (i) a
Permitted Transferee or (ii) pursuant to a Demand Request in accordance with
Section 5.1(b), the ROFO Seller hereby agrees to notify in writing (the “ROFO
Notice”) each of the stockholder Parties that is not a ROFO Seller (the “ROFO
Parties”) and the Company, of: (A) its desire to Transfer such shares of Common
Stock, (B) the number of shares proposed to be Transferred (the “ROFO Shares”)
and (C) the price at which the ROFO Seller is willing to sell the ROFO Shares
(the “ROFO Notice Price”), and (D) other terms of such proposed sale. The ROFO
Seller(s) will negotiate in good

 

20

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

with any ROFO Parties who express an interest in acquiring the ROFO Shares. The
ROFO Parties shall be entitled, but not required, within 21 days after the
delivery date of the ROFO Notice, to deliver a cash offer notice (an “ROFO Offer
Notice”) to the ROFO Seller of their offer for all, or any portion, of the ROFO
Shares set forth in the ROFO Notice. If any ROFO Offer Notice is accepted by the
ROFO Seller, each ROFO Party timely delivering a ROFO Offer Notice shall have
the right to acquire a pro rata number of ROFO Shares based on the relative
number of shares of Common Stock then owned by all of the ROFO Parties timely
delivering a ROFO Offer Notice.

(b) Unless the ROFO Seller and the ROFO Parties otherwise agree, in the event
ROFO Offer Notices at least equal to the ROFO Notice Price are not delivered to
the ROFO Seller on or prior to the date 21 days after the delivery date of the
ROFO Notice (the “ROFO Offer Deadline”), the offer shall be deemed rejected with
respect to such ROFO Shares so offered, and, at any time within 120 days after
the ROFO Offer Deadline, the ROFO Seller shall be entitled to sell any ROFO
Shares not Transferred pursuant to the ROFO Offer Notices for a cash price equal
to or greater than the ROFO Notice Price. After the expiration of such 120-day
period, if the ROFO Seller has not sold, the ROFO Seller may not Transfer the
ROFO Shares without complying again with the provisions of this Section 4.9.

(c) To the extent ROFO Offer Notices are delivered and are accepted or deemed
accepted by the ROFO Seller, the closing for the Transfer of the ROFO Shares
shall be consummated at 9:00 a.m. Oklahoma City time on the date 30 days
following the ROFO Offer Deadline, at the Company’s principal executive offices,
or at such other time, date and place as mutually agreed by the ROFO Seller and
the ROFO Parties. At the closing, the purchase price shall be paid in the form
of a cashier’s check or by wire transfer in same day funds, and the ROFO Seller
shall deliver stock certificates representing the ROFO Shares so purchased,
accompanied by duly executed stock powers, free and clear of all liens,
encumbrances and adverse claims (other than encumbrances as set forth in this
Agreement), and such other instruments or documents as are deemed necessary by
the Company for the proper Transfer of the ROFO Shares so transferred on the
books of the Company. The Company, the ROFO Seller, and the ROFO Parties shall
cooperate in good faith in obtaining all necessary governmental and third-party
consents, approvals or waivers required for the closing. The closing may be
delayed, to the extent required, until the next succeeding day following the
expiration of any required waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 and the obtaining of any necessary government
approvals; provided, that such delay shall not exceed 45 days, and if
governmental approvals and waiting periods shall not have been obtained or
expired, as the case may be, by such 45th day, then the relevant ROFO Offer
Notice shall be deemed to have been rejected and neither the ROFO Seller nor the
ROFO Parties shall have any further obligation with respect to such ROFO Offer
Notice.

ARTICLE 5

REGISTRATION RIGHTS;

PIGGYBACK REGISTRATION

5.1 Demand Registration Rights.

(a) At any time after a Qualified IPO (the “Demand Period”), Fischer may on up
to four occasions, and Altoma and Chesapeake may on up to two occasions each,
make a written request of the Company (a “Demand Request”) for registration
under the Securities Act (a “Demand Registration”) of Registrable Securities
held by the Fischer Parties, the Altoma Parties or Chesapeake, provided that
such Registrable Securities shall have proposed offering proceeds for such
offering that equals or exceeds US $20 million (or US $10 million in the event
the Company is able to register such Registrable Securities on Form S-3).

(b) In addition to the Demand Requests pursuant to Section 5.1(a), either Altoma
or Chesapeake may make one Demand Request for a Demand Registration at any time
after May 15, 2011 in the event a registration statement for a Qualified IPO has
not been filed or a Qualified IPO has not been consummated prior to such date,
provided that such Registrable Securities shall have proposed offering proceeds
for such offering that equals or exceeds US $20 million. However, the respective
rights of Altoma or Chesapeake set forth in this Section 5.1(b) shall terminate
and be of no further force and effect if the Board of Directors of the Company
recommends a transaction that would result in a Qualified IPO occurring prior to
August 15, 2011, and such party votes against the proposed transaction.

(c) The Company may defer the filing (but not the preparation) of a registration
statement required by this Section until a date not later than 60 days after the
Required Filing Date (as defined below) if (i) at the time the Company receives
the Demand Request, the Company or its Subsidiaries are engaged in confidential
negotiations, other confidential business activities or is otherwise in
possession of material non-public information, disclosure of which would be
required in such registration statement (but would not be required if such
registration statement were not filed), and the Board of Directors of the
Company determines in good faith that such disclosure would be materially
detrimental to the Company and its stockholders, (ii) an investment banking firm
advises the Company that effecting such registration would materially and
adversely affect an offering of securities of the Company, or (iii) prior to
receiving the Demand Request, the Board of Directors had determined to effect a
registered underwritten public offering of the Company’s equity securities for
the Company’s account and the Company had taken substantial steps (including,
but not limited to, selecting (subject to the terms of this Agreement) and
entering into a letter of intent with the managing Underwriter for such
offering) and is proceeding with reasonable diligence to effect such offering. A
deferral of the filing of a registration statement pursuant to this
Section 5.1(c) shall be lifted, and the requested registration statement shall
be filed forthwith, if: in the case of a deferral pursuant to clause (i) of the
preceding sentence, the negotiations or other activities are disclosed or
terminated; in the case of a deferral pursuant to clause (ii) of the preceding
sentence, such investment banking firm advises the Company that effecting such
registration would no longer materially and adversely affect an offering of
securities of the Company; or, in the case of a deferral pursuant to clause
(iii) of the preceding sentence, the proposed registration for the Company’s
account is abandoned. In order

 

22

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

to defer the filing of a registration statement pursuant to this subsection (b),
the Company shall promptly, upon determining to seek such deferral, deliver to a
requesting holder a certificate signed by the President or CEO of the Company
stating that the Company is deferring such filing pursuant to this
Section 5.1(c) and the basis therefor in reasonable detail. Within twenty
(20) days after receiving such certificate, the requesting holder for which
registration was previously requested may withdraw such request by giving notice
to the Company; if withdrawn, the Demand Request shall be deemed not to have
been made for all purposes of this Agreement. Notwithstanding the foregoing, the
Company may not defer the filing of a registration statement pursuant to this
Section 5.1(b) more than twice every 12 months.

(d) Each Demand Request shall specify the number of shares of Registrable
Securities proposed to be sold. Subject to subsection (c) of this Section 5.1,
the Company shall use its commercially reasonable efforts to file the Demand
Registration within 60 days after receiving a Demand Request (the “Required
Filing Date”) and shall use all commercially reasonable efforts to cause the
same to be declared effective by the SEC as promptly as practicable after such
filing, provided that the Company need effect only one Demand Registration at
any time in accordance with this Section. The Company shall pay all of its fees,
costs and expenses, other than underwriting discounts and commissions, related
to any such Demand Registration; provided, however, if the Demand Registration
is subsequently withdrawn by the Party or Parties initiating the Demand
Registration, the Party or Parties may decide either (i) to pay pro rata any
expenses of such registration and retain their rights to such Demand
Registration or (ii) to elect to have the Company bear such expenses (in which
event such Demand Registration shall count as one of such Party’s demands for
Demand Registration).

(e) Notwithstanding anything to the contrary contained in this Agreement, the
Company shall not be required to register any Person’s Registrable Securities
pursuant to a Demand Registration unless such Person accepts the terms of the
underwriting agreement between the Company and the Underwriter.

5.2 Notice; Piggyback Registration. Subject to the provisions of this Agreement,
if the Company proposes to file a registration statement under the Securities
Act with respect to an offering of any equity securities by the Company for its
own account or for the account of any of its equity holders, including a
registration statement filed pursuant to Section 5.1, (other than a registration
statement on Form S-4 or Form S-8 (or such corresponding forms adopted by the
SEC for use by foreign issuers), or any substitute form that may be adopted by
the SEC, or any registration statement filed in connection with an exchange
offer or offering of securities solely to the Company’s existing security
holders), then the Company shall give written notice of such proposed filing to
the Parties as soon as practicable (but in no event less than 30 days before the
anticipated effective date of such registration statement), and such notice
shall offer each such Party and its Permitted Transferees the opportunity to
register the Applicable Percentage of the Registrable Securities held by each
such Party and its Permitted Transferees (a “Piggyback Registration”). Subject
to the limitations in Sections 5.3, 5.4, 5.5, 5.6 and 5.9 hereof, the Company
shall include in each such Piggyback Registration all Registrable Securities
requested to be included in the registration for such offering. Each such holder
of Registrable Securities shall be permitted to withdraw all or part of such
holder’s Registrable Securities from a Piggyback Registration at any time prior
to the effective date thereof.

 

23

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

5.3 Obligations of the Company. Whenever required under this Section 5 to effect
the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

(a) Prepare and file with the SEC a registration statement with respect to such
Registrable Securities and use its commercially reasonable efforts to cause such
registration statement to be declared effective, and keep such registration
statement effective for up to 120 days; provided, however, that if Holders of
Registrable Securities holding shares having an aggregate value in excess of $10
million request that such registration statement be filed on Form S-3 under Rule
415 on a continuous basis and such filing is permitted under applicable SEC
rules, the Company shall keep such registration statement effective until all
such Registrable Securities are sold thereunder and/or cease to be Registrable
Securities, or for two years if earlier, provided that the aggregate value of
shares registered under such registration statement also exceeds $10 million.

(b) Prepare and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement for up to 120 days, or such longer period in connection
with a Rule 415 offering described in Section 5.3(a) above.

(c) Furnish to the Parties such numbers of copies of a prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them.

(d) Use its reasonable efforts to register and qualify the securities covered by
such registration statement under such other securities or “blue sky” laws of
such jurisdictions in the United States as shall be reasonably requested by the
Parties, provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions.

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

(f) Notify each Party covered by such registration statement at any time when a
prospectus relating thereto is required to be delivered under the Securities Act
of the happening of any event as a result of which the prospectus included in
such registration statement, as then in effect, includes an untrue statement of
a material fact or omits to state a material fact required to be stated therein
or necessary to make the statements therein not misleading in the light of the
circumstances then existing, such obligation to continue for 120 days, or such
longer period in connection with a Rule 415 offering described in Section 5.3(a)
above.

(g) Use its reasonable efforts to cause all such Registrable Securities
registered pursuant hereunder to be listed on each securities exchange on which
the same securities issued by the Company are then listed.

 

24

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

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

(i) Use its reasonable efforts to furnish, at the request of any Party
requesting registration of Registrable Securities pursuant to this Article 5, on
the date that such Registrable Securities are delivered to the underwriters for
sale in connection with a registration pursuant to this Article 5, if such
securities are being sold through underwriters, or, if such securities are not
being sold through underwriters, on the date that the registration statement
with respect to such securities becomes effective, (i) an opinion, dated such
date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and to
the Party or Parties requesting registration of Registrable Securities and
(ii) a letter dated such date, from the independent certified public accountants
of the Company, in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering,
addressed to the underwriters, if any, and to the Parties requesting
registration of Registrable Securities.

5.4 Indemnification. In the event any Registrable Securities are included in a
registration statement under this Section 5:

(a) To the extent permitted by law, the Company will indemnify and hold harmless
each Party, each of its officers, directors, partners, legal counsel,
accountants, and any underwriter (as defined in the Securities Act) for such
Party and each person, if any, who controls such Party or underwriter within the
meaning of the Securities Act or the Securities Exchange Act of 1934, as amended
(the “Exchange Act”), against any losses, claims, damages, or liabilities (joint
or several) to which they may become subject under the Securities Act, the
Exchange Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a “Violation”): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
the Exchange Act or any state securities law; and the Company will pay to each
such Party, each of its officers, directors, partners, legal counsel,
accountants, and any underwriter or controlling person, as incurred, any legal
or other expenses reasonably incurred by them in connection with investigating
or defending any such loss, claim, damage, liability, or action; provided,
however, that the indemnity agreement contained in this Section 5.4(a) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the consent of the Company
(which consent shall not be unreasonably withheld), nor shall the Company be
liable to any Party, each of its officers, directors, partners, legal counsel,
accountants, and any underwriter or controlling person for any such loss, claim,
damage, liability, or action to the extent that it arises out of or is based
upon a Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
any such Party, underwriter or controlling person.

 

25

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

(b) To the extent permitted by law, each selling Party will indemnify and hold
harmless the Company, each of its directors, each of its officers who has signed
the registration statement, each person, if any, who controls the Company within
the meaning of the Securities Act, legal counsel for the Company, accountants
for the Company, any underwriter, any other Party selling securities in such
registration statement and any controlling person of any such underwriter or
other Party, against any losses, claims, damages, or liabilities (joint or
several) to which any of the foregoing persons may become subject, under the
Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereto) arise
out of or are based upon any Violation, in each case to the extent (and only to
the extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Party expressly for use in connection with
such registration; and each such Party will pay, as incurred, any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant
to this Section 5.4(b), in connection with investigating or defending any such
loss, claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this Section 5.4(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Party, which consent shall not
be unreasonably withheld; provided, that in no event shall any indemnity under
this Section 5.4(b) exceed the net proceeds from the offering received by such
Party, except in the case of willful fraud by such Party.

(c) Promptly after receipt by an indemnified party under this Section 5.4 of
notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 5.4, deliver to the indemnifying party
a written notice of the commencement thereof and the indemnifying party shall
have the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
the defense thereof with counsel mutually satisfactory to the parties; provided,
however, that an indemnified party (together with all other indemnified parties
which may be represented without conflict by one counsel) shall have the right
to retain one separate counsel, with the reasonable fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 5.4, but the omission so to deliver written
notice to the indemnifying party will not relieve it of any liability that it
may have to any indemnified party otherwise than under this Section 5.4.

(d) If the indemnification provided for in Section 5.4 is held by a court of
competent jurisdiction to be unavailable to an indemnified party with respect to
any loss, liability, claim, damage or expense referred to therein, then the
indemnifying party, in lieu of indemnifying such indemnified party hereunder,
shall contribute to the amount paid or payable by such indemnified party as a
result of such loss, liability, claim, damage, or expense in such

 

26

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

proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage or expense as well as any other relevant equitable considerations;
provided, that in no event shall any contribution by a Party under this
Section 5.4(d) exceed the net proceeds from the offering received by such Party,
except in the case of willful fraud by such Party. The relative fault of the
indemnifying party and of the indemnified party shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party and the parties’
relative intent, knowledge, access to information, and opportunity to correct or
prevent such statement or omission.

(e) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control with respect to the Company and the Parties.

(f) The obligations of the Company and Parties under Section 5.4 shall survive
the completion of any offering of Registrable Securities in a registration
statement under this Article 5, and otherwise.

5.5 Reports Under Securities Exchange Act of 1934. With a view to making
available to the Parties the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Party to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:

(a) make and keep public information available, as those terms are understood
and defined in SEC Rule 144, at all times after 90 days after the effective date
of the first registration statement filed by the Company for the offering of its
securities to the general public so long as the Company remains subject to the
periodic reporting requirements under Sections 13 or 15(d) of the Exchange Act;

(b) take such action, including the voluntary registration of its Common Stock
under Section 12 of the Exchange Act, as is necessary to enable the Parties, if
requested pursuant to a Demand Registration, to utilize Form S-3 for the sale of
their Registrable Securities, such action to be taken as soon as practicable
after the end of the fiscal year in which the first registration statement filed
by the Company for the offering of its securities to the general public is
declared effective;

(c) 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; and

(d) furnish to any Party, so long as the Party owns any Registrable Securities,
forthwith upon request (i) a written statement by the Company that it has
complied with the reporting requirements of SEC Rule 144 (at any time after 90
days after the effective date of the first registration statement filed by the
Company), the Securities Act and the Exchange Act (at

 

27

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

any time after it has become subject to such reporting requirements), or that it
qualifies as a registrant whose securities may be resold pursuant to Form S-3
(at any time after it so qualifies), (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested in
availing any Party of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

5.6 No Assignment of Demand Rights. The rights to cause the Company to register
Registrable Securities pursuant to Section 5.1 may not be assigned to third
parties except to a Permitted Transferee either (i) controlled by Fischer,
Altoma or Chesapeake or (ii) controlling in excess of 40% of the outstanding
voting securities of Fischer as of the date of this Agreement.

5.7 Limitations on Subsequent Registration Rights. From and after the date of
this Agreement, the Company shall not enter into any agreement with any holder
or prospective holder of any securities of the Company which would grant such
holder or prospective holder registration rights that are more favorable than
the registration rights of the Parties.

5.8 Selection of Underwriters. The Board of Directors shall have the right to
designate, in their sole and absolute discretion, the book-running managing
Underwriter(s) (the “Managing Underwriter(s)”) with respect to any Piggyback
Registration or Demand Registration, or with respect to any other underwritten
public offering of Registrable Securities or other securities of the Company and
shall select such additional Underwriters to be used in connection with the
offering, if any. The Board of Directors shall also have the right to select one
or more co-managers for each such offering if the Board of Directors, in their
sole discretion, shall determine that any be necessary, and the underwriting
fees related to any such offering shall be allocated among any such co-managers
in such proportions as the Board of Directors shall determine. In the event of
any such offering, the Managing Underwriter(s), the Company and any Selling
Stockholders will enter into an agreement appropriate to the circumstances,
containing provisions for, among other things, compensation, indemnification,
contribution, and representations and warranties, which are usual and customary
for similar agreements entered into by the Managing Underwriter(s) or other
investment bankers of national standing acting in similar transactions.

5.9 Underwriters’ Cut-Backs. The Company shall use all commercially reasonable
efforts to cause the Managing Underwriter or any other managing Underwriter of a
proposed underwritten offering (including an offering pursuant to a Demand
Registration), as the case may be, to permit the Registrable Securities
requested to be included in the registration statement for such offering under
Section 5.2 or pursuant to other piggyback registration rights, if any, granted
by the Company (“Piggyback Securities”) to be included on the same terms and
conditions as any similar securities included therein. Notwithstanding the
foregoing, the Company shall not be required to include any Party’s Piggyback
Securities in such offering unless such Party accepts the terms of the
underwriting agreement between the Company and the Managing Underwriter (or
other managing Underwriter) or Underwriters, and otherwise complies with the
provisions of Section 5.10 below. If the managing Underwriter or Underwriters of
a proposed underwritten offering advise the Company in writing that in its or
their opinion the total amount of securities, including Piggyback Securities, to
be included in such offering is sufficiently large to potentially impede or
interfere with the offering, then in such event the securities to be included in
such

 

28

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

offering shall be allocated first to the Company and then, to the extent that
any additional securities can, in the opinion of such managing Underwriter or
Underwriters, be sold without any such potential to impede or interfere with the
offering, pro rata among the holders of Registrable Securities on the basis of
the number of Registrable Securities requested to be included in such
registration by each such holder.

5.10 Participation. No Party may participate in any underwritten registration
under this Article 5 unless such Party (i) agrees to sell such Party’s
Registrable Securities on the basis provided in any underwriting arrangements
approved by the Person entitled hereunder to approve such arrangements,
(ii) completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements and this Agreement and (iii) if requested by
another Person participating in such underwritten registration, agrees that all
securities convertible or exchangeable into shares of Common Stock that are
included in such underwritten registration shall be so converted or exchanged on
or prior to the consummation thereof.

5.11 Termination or Postponement by the Company. Notwithstanding anything herein
to the contrary except in the case of a Demand Registration, at any time prior
to the effectiveness of any registration statement filed pursuant hereto, the
Company shall have the right, in its sole and absolute discretion, not to
proceed with the registration of any securities pursuant to such registration
statement and, in the event that the Company exercises such right, no holder of
Registrable Securities shall have any right to require the Company to register
any such Registrable Securities except in accordance with the express provisions
of this Agreement. In the case of a registration statement filed pursuant
Section 5.1, at any time after the filing of such registration statement but
prior to the effectiveness thereof, the Company shall have the right to postpone
requesting that the SEC declare such registration statement effective:

(a) for the Contractual Lock-up Period relating to any underwritten public
offering of Company securities or any private placement of Company securities
made pursuant to Rule 144A; and

(b) for a period of up to 90 days if the Company is engaged in confidential
negotiations, other confidential business activities or is otherwise in
possession of material non-public information, disclosure of which would be
required in such registration statement (but would not be required if such
registration were not filed), and the Board of Directors of the Company
determines in good faith that such disclosure would be materially detrimental to
the Company and its stockholders;

provided, however, that the Company may not postpone requesting the
effectiveness of a registration statement filed pursuant to Section 5.1 pursuant
to this Section 5.11 more than twice every 12 months. The Company may only
terminate a Demand Registration and withdraw a registration statement filed
pursuant to Section 5.1 with the consent of the Party submitting the Demand
Request relating thereto or upon receipt of a request for such withdrawal from
the SEC.

5.12 Lock-Up Letters. Each holder of Registrable Securities (whether or not such
Registrable Securities are included in a registration statement pursuant hereto)
agrees to execute a written agreement not to effect any public sale or
distribution of the issue being registered or of

 

29

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

any securities convertible into or exchangeable or exercisable for such
securities, including a sale pursuant to Rule 144 under the Securities Act,
during the 14 days prior to, and during the 180-day period (or shorter period
permitted by the Managing Underwriter, if applicable) beginning on, the
effective date of a registration statement filed pursuant hereto except as part
of such registration if and to the extent requested by the Company, in the case
of a non-underwritten public offering, or if and to the extent requested by the
Managing Underwriter or managing Underwriter or Underwriters, as the case may
be, in the case of an underwritten public offering.

fact required to be stated therein or necessary to make the statements therein
not misleading, and that in the case of the prospectus, it will not contain any
untrue statement of a material fact or omit to state any material fact required

who manage their accounts).

6.3 Suspension Periods. In the event the Company has filed a registration
statement that has been declared effective by the SEC (including a registration
statement on Form S-3 under Rule 415 that provides for periodic resales by a
Selling Holder), the Company may provide notice to the Parties hereto that the
Company has elected to require the suspension of the sale by the Parties of
Registrable Securities (including securities registered under any such effective
registration statement) (a “Suspension Period”):

(a) for the Contractual Lock-up Period relating to any underwritten public
offering of Company securities or any private placement of Company securities
made pursuant to Rule 144A; and

(b) for a period of up to 90 days if the Company is engaged in confidential
negotiations, other confidential business activities or is otherwise in
possession of material non-public information, disclosure of which would be
required in such registration statement (but would not be required if such
registration were not filed), and the Board of Directors of the Company
determines in good faith that such disclosure would be materially detrimental to
the Company and its stockholders;

provided, however, that the Company may not cause a Suspension Period to occur
more than twice every 12 months.

Equivalents now owned or hereafter acquired by any of the Parties shall be
subject to, and entitled to the benefits of, the terms of this Agreement. The

and counsel are reasonably satisfactory to the Company and which opinion shall
be delivered to the Company in writing, either or both of such Restrictions are
