3.1. Permitted Transferees.

3.1.1. Affiliates. Subject to the provisions of Section 5.1, if applicable, any holder of Shares may Transfer any or all of such Shares to an Affiliate of such holder, provided, that the holders of the beneficial interests of such Affiliate have delivered to the Company and the Majority Investors a written acknowledgment and agreement in form and substance reasonably satisfactory to the Company and the Majority Investors that they will not Transfer any such beneficial interests or permit such Affiliate to issue any beneficial interests except to the extent such Transfer or issuance (treating such issuance as a Transfer by such holders) would be permitted under this Section 3.1 if the beneficial interests were Shares.

3.1.2. Upon Death. Subject to the provisions of Section 5.1, if applicable, upon the death of any holder of Shares who is a natural Person, such Shares may be distributed by the will or other instrument taking effect at death of such holder or by applicable laws of descent and distribution to such holder’s estate, executors, administrators and personal representatives, and then to such holder’s heirs, legatees or distributees, whether or not such recipients are Members of the Immediate Family of such holder.

Panther Stockholders_Agreement (Execution)		-3-

No Transfer permitted under the terms of this Section 3.1 will be effective unless the transferee of such Shares (each, a “Permitted Transferee”) has delivered to the Company a written acknowledgment and agreement in form and substance reasonably satisfactory to the Company that such Shares to be received by such Permitted Transferee will remain Investor Shares, Other Investor Shares or Management Shares, as the case may be, and will be subject to all of the provisions of this Agreement and that such Permitted Transferee will be bound by, and will be a party to, this Agreement as a holder of Investor Shares, Other Investor Shares or Management Shares, as the case may be, hereunder; provided, however, that Shares Transferred to any director, officer or employee of, or consultant or adviser to, the Company or any of its subsidiaries by a holder of Investor Shares will thereafter become Management Shares hereunder; and provided further that no Transfer by any holder of Shares to a Permitted Transferee will relieve such holder of any of its obligations hereunder.

3.2. Tag Alongs, Drag Alongs, Etc. In addition to Transfers permitted under Section 3.1:

(a) any holder of Investor Shares may Transfer such Shares if (i) such holder has complied with the “tag along” provisions contained in Section 4.1, (ii) the Majority Investors have exercised their “drag along” rights set forth in Section 4.2 or (iii) if, after giving effect to such Transfer, the Investors, their partners and Affiliates of any of the foregoing will continue to own not less than 80% of the Shares originally issued to the Investors; and

(b) any holder of Other Investor Shares or Management Shares may Transfer any or all of such Shares in accordance with the provisions, terms and conditions of Sections 4.1 and 4.2 solely in their capacity as Participating Sellers thereunder.

Panther Stockholders_Agreement (Execution)		-4-

4. “TAG ALONG” AND “DRAG ALONG” RIGHTS.

4.1. Tag Along. If one or more holders of Investor Shares (each such holder, a “Prospective Selling Investor”) proposes to Sell any such Shares to any Prospective Purchaser in a transaction (a) not constituting a Transfer pursuant to the terms of Sections 3.1 or 3.2(a)(iii) and (b) in connection with which the Majority Investors have not elected to exercise their “drag along” rights under Section 4.2:

4.1.1. Notice. The Prospective Selling Investors will deliver a written notice (the “Tag Along Notice”) to each other holder of Shares (each, a “Tag Along Holder”) at least ten business days prior to such proposed Transfer. The Tag Along Notice will include:

(a) The principal terms of the proposed Sale insofar it relates to such Shares, including (i) the number and class of the Shares to be purchased from the Prospective Selling Investors, (ii) the fraction(s) expressed as a percentage, determined by dividing the number of Shares of each class to be purchased from the Prospective Selling Investors by the total number of Investor Shares of each such class originally purchased by the Investors (the “Tag Along Sale Percentage”), (iii) the maximum and minimum per share purchase price and (iv) the name and address of the Prospective Purchaser; and

(b) An invitation to each Tag Along Holder to make an offer to include in the proposed Sale to the applicable Prospective Purchaser an additional number of Shares held by such Tag Along Holder (not in any event to exceed the Tag Along Sale Percentage of the total number of Shares of the applicable class held by such Tag Along Holder), on the same terms and conditions (subject to Section 4.3.4 in the case of Options, Warrants and Convertible Securities), with respect to each Share Sold, as the Prospective Selling Investors will Sell each of their Shares.

4.1.2. Exercise. Within five business days after the effectiveness of the Tag Along Notice, each Tag Along Holder desiring to make an offer to include issued and outstanding Shares in the proposed Sale (each a “Participating Seller” and, together with the Prospective Selling Investors, collectively, the “Tag Along Sellers”) will furnish a written notice (the “Tag Along Offer”) to the Prospective Selling Investors offering to include an additional number of Shares (not in any event to exceed the Tag Along Sale Percentage of the total number of Shares of the applicable class held by such Participating Seller) that such Participating Seller desires to have included in the proposed Sale. Each Tag Along Holder who does not accept the Prospective Selling Investors’ invitation to make an offer to include Shares in the proposed Sale will be deemed to have waived all of his rights with respect to such Sale, and the Tag Along Sellers will thereafter be free to Sell to the Prospective Purchaser, at a per share price no greater than the maximum per share price set forth in the Tag Along Notice and on other principal terms that are not materially more favorable to the Tag Along Sellers than those set forth in the Tag Along Notice, without any further obligation to such non-accepting Tag Along Holder.


Panther Stockholders_Agreement (Execution)		-5-

4.1.3. Irrevocable Offer. The offer of each Participating Seller contained in his Tag Along Offer will be irrevocable, and, to the extent such offer is accepted, such Participating Seller will be bound and obligated to Sell in the proposed Sale on the same terms and conditions, with respect to each Share Sold (subject to Section 4.3.4 in the case of Options, Warrants and Convertible Securities), as the Prospective Selling Investors, up to such number of Shares as such Participating Seller will have specified in his Tag Along Offer; provided, however, that if the principal terms of the proposed Sale change with the result that the per share price will be less than the minimum per share price set forth in the Tag Along Notice or the other principal terms will be materially less favorable to the Tag Along Sellers than those set forth in the Tag Along Notice, each Participating Seller will be permitted to withdraw the offer contained in his Tag Along Offer and will be released from his obligations thereunder.

4.1.4. Reduction of Shares Sold. The Prospective Selling Investors will attempt to obtain the inclusion in the proposed Sale of the entire number of Shares that each of the Tag Along Sellers requested to have included in the Sale (as evidenced in the case of the Prospective Selling Investors by the Tag Along Notice and in the case of each Participating Seller by such Participating Seller’s Tag Along Offer). In the event the Prospective Selling Investors will be unable to obtain the inclusion of such entire number of Shares in the proposed Sale, the number of Shares to be sold in the proposed Sale will be allocated among the Tag Along Sellers in proportion, as nearly as practicable, to the respective number of Shares that each Tag Along Seller requested to be included in the proposed Sale.

4.1.5. Additional Compliance. If (a) prior to consummation, the terms of the proposed Sale change with the result that the per share price to be paid in such proposed Sale will be greater than the maximum per share price set forth in the Tag Along Notice or the other principal terms of such proposed Sale will be materially more favorable to the Tag Along Sellers than those set forth in the Tag Along Notice, the Tag Along Notice will be null and void, and it will be necessary for a separate Tag Along Notice to be furnished, and the terms and provisions of this Section 4.1 separately complied with, in order to consummate such proposed Sale pursuant to this Section 4.1; provided, however, that in the case of such a separate Tag Along Notice, the applicable period to which reference is made in Sections 4.1.1 and 4.1.2 will be five business days and three business days, respectively, and (b) the Prospective Selling Investors have not completed the proposed Sale by the end of the 180th day following the date of the effectiveness of the Tag Along Notice, each Participating Seller will be released from his obligations under his Tag Along Offer, the Tag Along Notice will be null and void, and it will be necessary for a separate Tag Along Notice to be furnished, and the terms and provisions of this Section 4.1 separately complied with, in order to consummate such proposed Sale pursuant to this Section 4.1, unless the failure to complete such proposed Sale resulted from any failure by any Participating Seller to comply with the terms of this Section 4.

4.1.6. Classes of Shares. Notwithstanding the foregoing provisions of this Section 4.1, the right of any Tag Along Holder to include Shares in any Sale in accordance with this Section 4.1 shall be limited to a right to include Shares in such Sale


Panther Stockholders_Agreement (Execution)		-6-

which are of the same Class as the Shares to be included in such Sale by the Prospective Selling Investors, and all determinations under this Section 4.1 shall be made on the basis of the holdings of Shares of the Class of Shares to be included in such Sale by the Prospective Selling Investor (including the Tag Along Sale Percentage).

4.2. Drag Along. Each holder of Shares hereby agrees, if requested by the Majority Investors, to Sell a specified percentage (the “Drag Along Sale Percentage”) of such Shares, directly or indirectly, to a Prospective Purchaser in the manner and on the terms set forth in this Section 4.2 in connection with the Sale by one or more holders of Investor Shares (each such holder, a “Prospective Selling Investor”) of the Drag Along Sale Percentage of the total number of Investor Shares held by all holders of Investor Shares to the Prospective Purchaser.

4.2.1. Exercise. If the Majority Investors elect to exercise their rights under this Section 4.2, the Prospective Selling Investors will furnish a written notice (the “Drag Along Notice”) to each other holder of Shares. The Drag Along Notice will set forth the principal terms of the proposed Sale insofar as it relates to such Shares including (i) the number and class of Shares to be acquired from the Prospective Selling Investors, (ii) the Drag Along Sale Percentage, (iii) the per share consideration to be received in the proposed Sale and (iv) the name and address of the Prospective Purchaser. If the Prospective Selling Investors consummate the proposed Sale to which reference is made in the Drag Along Notice, each other holder of Shares (each a “Participating Seller”, and, together with the Prospective Selling Investors, collectively, the “Drag Along Sellers”) will be bound and obligated to Sell the Drag Along Sale Percentage of his Shares in the proposed Sale on the same terms and conditions, with respect to each Share Sold (subject to Section 4.3.4 in the case of Options, Warrants and Convertible Securities), as the Prospective Selling Investors will Sell each Investor Share in the Sale (subject to Section 4.3.4 in the case of Options, Warrants and Convertible Securities). If at the end of the 180th day following the date of the effectiveness of the Drag Along Notice the Prospective Selling Investors have not completed the proposed Sale, the Drag Along Notice will be null and void, each Participating Seller will be released from his obligation under the Drag Along Notice and it will be necessary for a separate Drag Along Notice to be furnished and the terms and provisions of this Section 4.2 separately complied with, in order to consummate such proposed Sale pursuant to this Section 4.2.

4.2.2. Classes of Shares. Notwithstanding the foregoing provisions of this Section 4.2, the obligation of any holder of Shares to include Shares in any Sale in accordance with this Section 4.2 shall be limited to an obligation to include Shares in such Sale which are of the same Class as the Shares to be included in such Sale by the Prospective Selling Investors, and all determinations under this Section 4.2 shall be made on the basis of the holdings of Shares of the Class of Shares to be included in such Sale by the Prospective Selling Investor (including the Drag Along Sale Percentage).


Panther Stockholders_Agreement (Execution)		-7-

4.3. Miscellaneous. The following provisions will be applied to any proposed Sale to which Section 4.1 or 4.2 applies:

4.3.1. Certain Legal Requirements. In the event the consideration to be paid in exchange for Shares in a proposed Sale pursuant to Section 4.1 or Section 4.2 includes any securities, and the receipt thereof by a Participating Seller would require under applicable law (a) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities or (b) the provision to any Tag Along Seller or Drag Along Seller of any information regarding the Company, such securities or the issuer thereof, such Participating Seller will not have the right to Sell Shares in such proposed Sale. In such event, the Prospective Selling Investors will have the right, but not the obligation, to cause to be paid to such Participating Seller in lieu thereof, against surrender of the Shares (in accordance with Section 4.3.6 hereof) that would have otherwise been Sold by such Participating Seller to the Prospective Purchaser in the proposed Sale, an amount in cash equal to the Fair Market Value of such Shares as of the date such securities would have been issued in exchange for such Shares.

4.3.2. Further Assurances. Each Participating Seller, whether in his capacity as a Participating Seller, stockholder, officer or director of the Company, or otherwise, will take or cause to be taken all such actions as may be necessary or reasonably desirable in order expeditiously to consummate each Sale pursuant to Section 4.1 or 4.2 and any related transactions, including, without limitation, executing, acknowledging and delivering consents, assignments, waivers and other documents or instruments; furnishing information and copies of documents; filing applications, reports, returns, filings and other documents or instruments with governmental authorities; and otherwise cooperating with the Prospective Selling Investors and the Prospective Purchaser; provided, however, that Participating Sellers will be obligated to become liable in respect of any representations, warranties, covenants, indemnities or otherwise to the Prospective Purchaser solely to the extent provided in the immediately following sentence. Without limiting the generality of the foregoing, each Participating Seller agrees to execute and deliver such agreements as may be reasonably specified by the Prospective Selling Investors to which such Prospective Selling Investors will also be party, including, without limitation, agreements to (i) (a) make individual representations, warranties, covenants and other agreements as to the unencumbered title to its Shares and the power, authority and legal right to Transfer such Shares and the absence of any Adverse Claim with respect to such Shares and (b) be liable without limitation as to such representations, warranties, covenants and other agreements and (ii) be liable (whether by purchase price adjustment, indemnity payments or otherwise) in respect of representations, warranties, covenants and agreements in respect of the Company and its subsidiaries; provided, however, that the aggregate amount of liability described in this clause (ii) in connection with any Sale of Shares will not exceed the lesser of (i) such Participating Seller’s pro rata portion of any such liability, to be determined in accordance with such Participating Seller’s portion of the total number of Shares included in such Sale, or (ii) the proceeds to such Participating Seller in such Sale.

4.3.3. Sale Process. The Investors will, in their sole discretion, decide whether or not to pursue, consummate, postpone or abandon any proposed Sale and the terms and conditions thereof. No Investor or any Affiliate of any Investor will have any liability to


Panther Stockholders_Agreement (Execution)		-8-

any other holder of Shares arising from, relating to or in connection with the pursuit, consummation, postponement, abandonment or terms and conditions of any proposed Sale, except to the extent such Investor will have failed to comply with the provisions of this Section 4.

4.3.4. Treatment of Options, Warrants and Convertible Securities. Each Participating Seller agrees that to the extent he desires or is obligated to include Options, Warrants or Convertible Securities in any Sale of Shares pursuant to Section 4, he will be deemed to have exercised, converted or exchanged such Options, Warrants or Convertible Securities immediately prior to the closing of such Sale to the extent necessary to Sell Common Stock to the Prospective Purchaser, except to the extent permitted under the terms of any such Option, Warrant or Convertible Security and agreed by the Prospective Purchaser. If any Participating Seller will Sell Options, Warrants or Convertible Securities in any Sale pursuant to Section 4, such Participating Seller will receive in exchange for such Options, Warrants or Convertible Securities consideration equal to the amount (if greater than zero) determined by multiplying (a) the purchase price per share of Common Stock received by the holders of the Prospective Selling Investors in such Sale less the exercise price, if any, per share of such Option, Warrant or Convertible Security by (b) the number of shares of Common Stock issuable upon exercise, conversion or exchange of such Option, Warrant or Convertible Security (to the extent exercisable, convertible or exchangeable at the time of such Sale), subject to reduction for any tax or other amounts required to be withheld under applicable law.

4.3.5. Expenses. All costs and expenses incurred by the Prospective Selling Investors or the Company in connection with any proposed Sale pursuant to this Section 4 (whether or not consummated), including without limitation all attorneys fees and expenses, all accounting fees and charges and all finders, brokerage or investment banking fees, charges or commissions, will be paid by the Company. The reasonable fees and expenses of a single legal counsel representing any or all of the other Tag Along Sellers or Drag Along Sellers (including any participating Managers) in connection with any proposed Sale pursuant to this Section 4 (whether or not consummated) will be paid by the Company. Any other costs and expenses incurred by or on behalf of any or all of the other Tag Along Sellers or Drag Along Sellers in connection with any proposed Sale pursuant to this Section 4 (whether or not consummated) will be borne by such Tag Along Seller(s) or Drag Along Seller(s).

4.3.6. Closing. The closing of a Sale to which Section 4.1 or 4.2 applies will take place at such time and place as the Prospective Selling Investors will specify by notice to each Participating Seller. At the closing of such Sale, each Participating Seller will deliver the certificates evidencing the Shares to be Sold by such Participating Seller, duly endorsed, or with stock (or equivalent) powers duly endorsed, for transfer with signature guaranteed, free and clear of any liens or encumbrances, with any stock (or equivalent) transfer tax stamps affixed, against delivery of the applicable consideration.


Panther Stockholders_Agreement (Execution)		-9-

4.4. Period. The foregoing provisions of this Section 4 will expire on the earlier of (a) a Change of Control or (b) the effectiveness of the Company’s registration statement in connection with a Qualified Public Offering.

5. OPTIONS TO PURCHASE OR SELL SHARES.

5.1. Call Option. Except as the Company may otherwise agree with any Manager with respect to his Shares, upon any termination of the employment by the Company and its subsidiaries of any holder of Management Shares the Company will have the right to purchase for cash (or notes to the extent provided below in Section 5.2) all or any portion of the Management Shares that are not Options held by such holder or originally issued to such holder but held by one or more Permitted Transferees on the following terms (the “Call Option”):

5.1.1. Termination.

5.1.1.1. Termination due to Death or Disability or by Company other than for Cause or by the Holder. If such termination is the result of (i) the death or disability of such holder, (ii) termination of such holder’s employment by the Company other than for Cause or (iii) termination of such holder’s employment by such holder then, in any such event, the Company may purchase all or any portion of the Management Shares that are not Options held by such holder (or Permitted Transferee, if applicable) at a per Share price equal to the Fair Market Value of such Shares.

5.1.1.2. Termination by Company for Cause. If such termination is the result of termination of such holder’s employment by the Company for Cause then the Company may purchase all or any portion of the Management Shares that are not Options held by such holder (or Permitted Transferee, if applicable) at a per Share price equal to the lesser of the Cost or the Fair Market Value of such Shares.

5.1.2. Notices, Etc. Any Call Option may be exercised by delivery of written notice thereof (the “Call Notice”) to the applicable holder of Management Shares not later than the 70th day (or, in the case of a termination resulting from the death of such holder, the 130th day) after the effectiveness of the applicable termination of employment (the “Call Option Exercise Period”). The Call Notice will state that the Company has elected to exercise the Call Option, and the number and price of the Shares with respect to which the Call Option is being exercised.

5.2. Form of Payment. In each case Shares are purchased pursuant to Section 5.1, the Company will pay for such Shares by (i) paying the holder not less than one-half of the purchase price in cash, as determined by the Board and (ii) issuing for the balance of the purchase price not so paid in cash a promissory note in a principal amount equal to such balance. The principal of such note will be due and payable in four equal annual installments, the first such installment becoming due and payable on the first anniversary of the issuance of such note, and interest will accrue thereon at a rate equal to the applicable federal rate and be payable annually in arrears, in

each case subject to the provisions of this Section 5.2; provided, however, that if any payment of cash required upon the purchase and sale of Shares upon the exercise of any Call Option or any payment on a promissory note issued under Section 5.1 would (a) constitute, result in or give rise to any breach or violation of, or any default or right or cause of action under, any agreement to which the Company or any of its subsidiaries is, from time to time, a party or (b) leave the Company and its subsidiaries with less cash or borrowing availability than, in the good faith judgment of the Board, is necessary to operate the business of the Company and its subsidiaries in the ordinary course of business, then,

(i) in the case of a cash payment due at a closing of any purchase and sale of Shares upon the exercise of any Call Option, the Company will issue a promissory note in the aggregate principal amount of such payment, the principal amount of which note will be due and payable in four equal annual installments, the first such installment becoming due and payable on the first anniversary of the issuance of such note, and interest will accrue thereon at a rate equal to the applicable federal rate and be payable annually in arrears, in each case subject to the provisions of clause (ii) below, and

(ii) in the case of the cash payment in respect of a promissory note issued under this Section 5.2, notwithstanding any of the provisions of such note, including without limitation, the stated maturity of such note and the stated date on which interest payments are due, such payment will not become due and payable until such time as such payment can be made without violating any such agreement and not resulting in the Company and its subsidiaries having less cash or borrowing availability than the Board determines is necessary to operate the business as contemplated above.

Any promissory note issued under this Section 5.2 may be prepaid in whole or in part at any time and from time to time without premium or penalty.

5.3. Closing.

5.3.1. The closing of any purchase and sale of Shares pursuant to this Section 5 will take place as soon as reasonably practicable and in no event later than 30 days after termination of the Call Option Exercise Period at the principal office of the Company, or at such other time and location as the parties to such purchase may mutually determine.

5.3.2. At the closing of any purchase and sale of Shares following the exercise of any Call Option, the holders of Shares to be sold will deliver to the Company a certificate or certificates representing the Shares to be purchased by the Company duly endorsed, or with stock (or equivalent) powers duly endorsed, for transfer with signature guaranteed, free and clear of any lien or encumbrance, with any necessary stock (or equivalent) transfer tax stamps affixed, and the Company will pay to such holder by certified or bank check or wire transfer of immediately available federal funds or note, as may be applicable, the purchase price of the Shares being purchased by the Company. The delivery of a certificate or certificates for Shares by any Person selling Shares pursuant to


Panther Stockholders_Agreement (Execution)		-11-

any Call Option will be deemed a representation and warranty by such Person that: (i) such Person has full right, title and interest in and to such Shares; (ii) such Person has all necessary power and authority and has taken all necessary action to sell such Shares as contemplated; (iii) such Shares are free and clear of any and all liens or encumbrances and (iv) there is no Adverse Claim with respect to such Shares.

5.4. Acknowledgment. Each holder of Management Shares acknowledges and agrees that neither the Company nor any Person directly or indirectly affiliated with the Company (in each case whether as a director, officer, manager, employee, agent or otherwise) will have any duty or obligation to affirmatively disclose to him, and he will not have any right to be advised of, any material information regarding the Company or otherwise at any time prior to, upon, or in connection with (i) any termination of his employment by the Company and its subsidiaries or (ii) the exercise of any Call Option or any purchase of the Shares pursuant thereto.

5.5. Period. The foregoing provisions of this Section 5 will expire upon the earlier of (a) a Change of Control and (b) the effectiveness of the Company’s registration statement in connection with a Qualified Public Offering.

6. RIGHT OF PARTICIPATION.

The Company will not issue or sell any shares of any of its capital stock or any securities convertible into or exchangeable for any shares of its capital stock, issue or grant any options or warrants for the purchase of, or enter into any agreements providing for the issuance (contingent or otherwise) of, any of its capital stock or any stock or securities convertible into or exchangeable for any shares of its capital stock, in each case, to any Investor, any Affiliated Fund or any limited partner of an Investor (each an “Issuance” of “Subject Securities”), except in compliance with the provisions of Section 6.1 or 6.2.

6.1. Right of Participation.

6.1.1. Offer. Not fewer than fifteen days prior to the consummation of an Issuance, a notice (the “Participation Notice”) will be furnished by the Company to each holder of Investor Shares and Other Investor Shares (the “Participation Offerees”). The Participation Notice will include:

(a) The principal terms of the proposed Issuance, including, without limitation, (i) the amount and kind of Subject Securities to be included in the Issuance, (ii) the number of Equivalent Shares represented by such Subject Securities (if applicable), (iii) the percentage of the total number of Shares consisting of Common Stock outstanding as of immediately prior to giving effect to such Issuance that the number of Shares consisting of Common Stock held by such Participation Offeree constitutes (the “Participation Portion”), (iv) the maximum and minimum price (including, without limitation, if applicable, the maximum and minimum Price Per Equivalent Share) per unit of the Subject Securities and (v) the name and address of the Investor or Affiliated Fund to whom the Subject Securities will be issued (the “Prospective Subscriber”); and


Panther Stockholders_Agreement (Execution)		-12-

(b) An offer by the Company to issue, at the option of each Participation Offeree, to such Participation Offeree such portion of the Subject Securities to be included in the Issuance as may be requested by such Participation Offeree (not to exceed the Participation Portion of the total amount of Subject Securities to be included in the Issuance), on the same economic terms and conditions, with respect to each unit of Subject Securities issued to the Participation Offerees, as each of the Prospective Subscribers will be issued units of Subject Securities.

6.1.2. Exercise.

6.1.2.1. General. Each Participation Offeree desiring to accept the offer contained in the Participation Notice will send a written commitment to the Company within ten days after the effectiveness of the Participation Notice specifying the amount of Subject Securities (not in any event to exceed the Participation Portion of the total amount of Subject Securities to be included in the Issuance) that such Participation Offeree desires to be issued (each such Participation Offeree desiring to purchase Subject Securities, a “Participating Purchaser”). Each Participation Offeree who has not so accepted such offer will be deemed to have waived all of his rights with respect to the Issuance, and the Company will thereafter be free to issue Subject Securities in the Issuance to the Prospective Subscriber and any Participating Purchasers, at a price no less than the minimum price set forth in the Participation Notice and on other principal terms not substantially more favorable to the Prospective Subscriber than those set forth in the Participation Notice, without any further obligation to such non-accepting Participation Offerees with respect to such proposed issuance. If, prior to consummation, the terms of such proposed Issuance will change with the result that the price will be less than the minimum price set forth in the Participation Notice or the other principal terms will be substantially more favorable to the Prospective Subscriber than those set forth in the Participation Notice, it will be necessary for a separate Participation Notice to be furnished, and the terms and provisions of this Section 6.1 separately complied with, in order to consummate such Issuance pursuant to this Section 6.1.

6.1.2.2. Irrevocable Acceptance. The acceptance of each Participating Purchaser will be irrevocable except as hereinafter provided, and each such Participating Purchaser will be bound and obligated to acquire in the Issuance on the same terms and conditions, with respect to each unit of Subject Securities issued, as the Prospective Subscriber, such amount of Subject Securities as such Participating Purchaser will have specified in such Participating Purchaser’s written commitment.

6.1.2.3. Time Limitation. If at the end of the 180th day following the date of the effectiveness of the Participation Notice the Company has not completed the Issuance, each Participating Purchaser will be released from his obligations under the written commitment, the Participation Notice will be null


Panther Stockholders_Agreement (Execution)		-13-

and void, and it will be necessary for a separate Participation Notice to be furnished, and the terms and provisions of this Section 6.1 separately complied with, in order to consummate such Issuance pursuant to this Section 6.1.

6.1.3. Other Securities. The Company may condition the participation of the Participation Offerees in an Issuance upon the purchase by such Participation Offerees of any securities (including, without limitation, debt securities) other than Subject Securities (“Other Securities”) in the event that the participation of the Prospective Subscriber in such Issuance is so conditioned. In such case, each Participating Purchaser will acquire in the Issuance, together with the Subject Securities to be acquired by it, Other Securities in the same proportion to the Subject Securities to be acquired by it as the proportion of Other Securities to Subject Securities being acquired by the Prospective Subscriber in the Issuance, on the same terms and conditions, as to each unit of Subject Securities and Other Securities issued to the Participating Purchasers, as the Prospective Subscriber will be issued units of Subject Securities and Other Securities.

6.1.4. Certain Legal Requirements. In the event that the participation in the Issuance by a holder of Shares as a Participating Purchaser would require under applicable law (i) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities or (ii) the provision to any participant in the Sale of any information regarding the Company or the securities, such holder of Shares will not have the right to participate in the Issuance. Without limiting the generality of the foregoing, it is understood and agreed that the Company will not be under any obligation to effect a registration of such securities under the Securities Act or similar state statutes.

6.1.5. Further Assurances. Each Participation Offeree and each Stockholder to whom the Shares held by such Participation Offeree were originally issued, will, whether in his capacity as a Participating Purchaser, Stockholder, officer or director of the Company, or otherwise, take or cause to be taken all such reasonable actions as may be necessary or reasonably desirable in order expeditiously to consummate each Issuance pursuant to this Section 6.1 and any related transactions, including, without limitation, executing, acknowledging and delivering consents, assignments, waivers and other documents or instruments; filing applications, reports, returns, filings and other documents or instruments with governmental authorities; and otherwise cooperating with the Company and the Prospective Subscriber. Without limiting the generality of the foregoing, each such Participating Purchaser and Stockholder agrees to execute and deliver such subscription and other agreements specified by the Company to which the Prospective Subscriber will be party.

6.1.6. Expenses. All reasonable costs and expenses incurred by the holders of Investor Shares or the Company in connection with any proposed Issuance of Subject Securities (whether or not consummated), including without limitation all attorney’s fees and charges, all accounting fees and charges and all finders, brokerage or investment banking fees, charges or commissions, will be paid by the Company. The reasonable fees and expenses of a single legal counsel representing any or all of the other holders of


Panther Stockholders_Agreement (Execution)		-14-

Shares in connection with such proposed Issuance of Subject Securities (whether or not consummated) will be paid by the Company. Any other costs and expenses incurred by or on behalf of any other holder of Shares in connection with such proposed Issuance of Subject Securities (whether or not consummated) will be borne by such holder.

6.1.7. Closing. The closing of an Issuance pursuant to Section 6.1 will take place at such time and place as the Company will specify by notice to each Participating Purchaser. At the Closing of any Issuance under this Section 6.1.7, each Participating Purchaser will be delivered the notes, certificates or other instruments evidencing the Subject Securities (and, if applicable, Other Securities) to be issued to such Participating Purchaser, registered in the name of such Participating Purchaser or his designated nominee, free and clear of any liens or encumbrances, with any transfer tax stamps affixed, against delivery by such Participating Purchaser of the applicable consideration.

6.2. Post-Issuance Notice. Notwithstanding the notice requirements of Sections 6.1.1 and 6.1.2, the Company may proceed with any Issuance prior to having complied with the provisions of Section 6.1; provided, that the Company will:

(a) provide to each holder of Shares who would have been a Participation Offeree in connection with such Issuance (i) with prompt notice of such Issuance and (ii) the Participation Notice described in Section 6.1.1 in which the actual price per unit of Subject Securities (and, if applicable, actual Price Per Equivalent Share) will be set forth; and

(b) include in the subscription (or similar) agreement with the purchaser(s) of the Subject Securities and, if applicable, Other Securities, a provision permitting the Company to repurchase such securities in an amount necessary to satisfy the offers made by holders of Shares in accordance the provisions of Section 6.1.2 in response to the Participation Notice furnished pursuant to clause (a) above.

6.3. Excluded Transactions. Notwithstanding the preceding provisions of this Section 6, the preceding provisions of this Section 6 will not restrict:

(a) Any Issuance of Common Stock upon the exercise or conversion of any Common Stock, Options or Convertible Securities outstanding on the date hereof or issued after the date hereof in compliance with the provisions of this Section 6;

(b) The Issuance of Shares to the Investors at Closing; and

(c) Any Issuance of capital stock in connection with the financing of any business combination or business acquisition transaction involving the Company or any of its subsidiaries.

6.4. Acquired Shares. Any Subject Securities constituting shares of capital stock acquired by any holder of Shares pursuant to this Section 6 will be deemed for all purposes hereof to be Investor Shares or Other Investor Shares hereunder of like kind with the Shares then held by the acquiring holder.


Panther Stockholders_Agreement (Execution)		-15-

6.5. Period. The foregoing provisions of this Section 6 will expire on the earlier of (a) a Change of Control or (b) the effectiveness of the Company’s registration statement in connection with an Initial Public Offering.

7. REGISTRATION RIGHTS.

The Company will perform and comply, and cause each of its subsidiaries to perform and comply, with such of the following provisions as are applicable to it. Each holder of Shares will perform and comply with such of the following provisions as are applicable to such holder.

7.1. Demand Registration Rights for Investor Shares.

7.1.1. General. One or more holders of Investor Shares representing at least 25% of the total amount of Investor Shares then outstanding (“Initiating Investors”), by notice to the Company specifying the intended method or methods of disposition, may request that the Company effect the registration under the Securities Act for a Public Offering of all or a specified part of the Registrable Securities held by such Initiating Investors (for purposes of this Agreement, “Registrable Investor Securities” will mean Registrable Securities constituting Investor Shares). The Company will then use its best efforts to effect the registration under the Securities Act of the Registrable Securities that the Company has been requested to register by such Initiating Investors together with all other Registrable Securities that the Company has been requested to register pursuant to Section 7.2 or by other holders of Registrable Investor Securities by notice delivered to the Company within 20 days after the Company has given the notice required by Section 7.2.1 (which request will specify the intended method of disposition of such Registrable Securities), all to the extent requisite to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities that the Company has been so requested to register; provided, however, that the Company will not be obligated to take any action to effect any such registration pursuant to this Section 7.1.1 within 180 days immediately following the effective date of any registration statement pertaining to an underwritten public offering of securities of the Company for its own account (other than a Rule 145 Transaction or a registration relating solely to employee benefit plans).

7.1.2. Form. Each registration requested pursuant to Section 7.1.1 will be effected by the filing of a registration statement on Form S-l (or any other form that includes substantially the same information as would be required to be included in a registration statement on such form as currently constituted), unless the use of a different form has been agreed to in writing by holders of at least a majority of the Registrable Investor Securities to be included in the proposed registration statement in question (the “Majority Participating Investors”).

7.1.3. Payment of Expenses. The Company will pay all reasonable expenses of holders of Investor Shares incurred in connection with each registration of Registrable Securities requested pursuant to this Section 7.1, other than underwriting discount and commission, if any, and applicable transfer taxes, if any.


Panther Stockholders_Agreement (Execution)		-16-

7.1.4. Additional Procedures. In the case of a registration pursuant to Section 7.1 hereof, whenever the Majority Participating Investors will request that such registration will be effected pursuant to an underwritten offering, the Company will include such information in the written notices to holders of Registrable Securities referred to in Section 7.2. In such event, the right of any holder of Registrable Securities to have securities owned by such holder included in such registration pursuant to Section 7.1 will be conditioned upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed upon by the Majority Participating Investors and such holder). If requested by such underwriters, the Company together with the holders of Registrable Securities proposing to distribute their securities through such underwriting will enter into an underwriting agreement with such underwriters for such offering containing such representations and warranties by the Company and such holders and such other terms and provisions as are customarily contained in underwriting agreements with respect to secondary distributions, including, without limitation, customary indemnity and contribution provisions (subject, in each case, to the limitations on such liabilities set forth in this Agreement).

7.2. Piggyback Registration Rights.

7.2.1. Piggyback Registration.

7.2.1.1. General. Each time the Company proposes to register any shares of Common Stock under the Securities Act on a form that would permit registration of Registrable Securities for sale to the public, for its own account and/or for the account of an Investor or an Affiliated Fund (pursuant to Section 7.1 or otherwise) for sale in a Public Offering, the Company will give notice to all holders of Registrable Securities of its intention to do so. Any such holder may, by written response delivered to the Company within 20 days after the effectiveness of such notice, request that all or a specified part of the Registrable Securities held by such holder be included in such registration. The Company thereupon will use its reasonable efforts to cause to be included in such registration under the Securities Act all shares of Common Stock that the Company has been so requested to register by such holders, to the extent required to permit the disposition (in accordance with the methods to be used by the Company or other holders of shares of Common Stock in such Public Offering) of the Registrable Securities to be so registered. No registration of Registrable Securities effected under this Section 7.2 will relieve the Company of any of its obligations to effect registrations of Registrable Securities pursuant to Section 7.1 hereof.


Panther Stockholders_Agreement (Execution)		-17-

7.2.1.2. Excluded Transactions. The Company will not be obligated to effect any registration of Registrable Securities under this Section 7.2 incidental to the registration of any of its securities in connection with:

(a) Any Public Offering relating to employee benefit plans or dividend reinvestment plans;

(b) Any Public Offering relating to the acquisition or merger after the date hereof by the Company or any of its subsidiaries of or with any other businesses; or

(c) The Initial Public Offering, unless (i) such offering will have been initiated by the Investors pursuant to Section 7.1.1 or (ii) one or more Investors will have requested that all or a specified part of its Registrable Securities be included in such offering pursuant to this Section 7.2.1.

7.2.2. Payment of Expenses. The Company will pay all reasonable expenses of a single legal counsel representing any and all holders of Registrable Securities incurred in connection with each registration of Registrable Securities requested pursuant to this Section 7.2.

7.2.3. Additional Procedures. Holders of Shares participating in any Public Offering pursuant to this Section 7.2 will take all such actions and execute all such documents and instruments that are reasonably requested by the Company to effect the sale of their Shares in such Public Offering, including, without limitation, being parties to the underwriting agreement entered into by the Company and any other selling shareholders in connection therewith and being liable in respect of the representations and warranties by, and the other agreements (including without limitation customary selling stockholder representations, warranties, indemnifications and “lock-up” agreements) for the benefit of the underwriters; provided, however, that (a) with respect to individual representations, warranties, indemnities and agreements of sellers of Shares in such Public Offering, the aggregate amount of such liability will not exceed such holder’s net proceeds actually received by such holder from such offering and (b) to the extent selling stockholders give further representations, warranties and indemnities, then with respect to all other representations, warranties and indemnities of sellers of shares in such Public Offering, the aggregate amount of such liability will not exceed the lesser of (i) such holder’s pro rata portion of any such liability, in accordance with such holder’s portion of the total number of Shares included in the offering or (ii) such holder’s net proceeds actually received by such holder from such offering.

7.3. Certain Other Provisions.

7.3.1. Underwriter’s Cutback. In connection with any registration of shares, the underwriter may determine that marketing factors (including, without limitation, an adverse effect on the per share offering price) require a limitation of the number of shares


Panther Stockholders_Agreement (Execution)		-18-

to be underwritten. Notwithstanding any contrary provision of this Section 7 and subject to the terms of this Section 7.3.1, the underwriter may limit the number of shares that would otherwise be included in such registration by excluding any or all Registrable Securities from such registration (it being understood that the number of shares that the Company seeks to have registered in such registration will not be subject to exclusion, in whole or in part, under this Section 7.3.1). Upon receipt of notice from the underwriter of the need to reduce the number of shares to be included in the registration, the Company will advise all holders of the Company’s securities that would otherwise be registered and underwritten pursuant hereto, and the number of shares of such securities, including Registrable Securities, that may be included in the registration will be allocated in the following manner, unless the underwriter will determine that marketing factors require a different allocation: shares, other than Registrable Securities, requested to be included in such registration by shareholders will be excluded unless the Company has, with the consent of the Majority Investors, granted registration rights that are to be treated on an equal basis with Registrable Securities for the purpose of the exercise of the underwriter cutback (in which case Shares of Common Stock that are subject to such registration rights will be treated as Registrable Securities for purposes of this Section 7.3.1); and, if a limitation on the number of shares is still required, the number of Registrable Securities that may be included in such registration will be allocated among holders thereof in proportion, as nearly as practicable, to the respective amounts of Registrable Securities that may be included in such registration held by each such holder. For purposes of any underwriter cutback, all Registrable Securities held by any holder of Registrable Securities will also include any Registrable Securities held by the partners, retired partners, shareholders or affiliated entities of such holder, or the estates and family members of any such holder or such partners and retired partners, any trusts for the benefit of any of the foregoing persons and, at the election of such holder or such partners, retired partners, trusts or affiliated entities, and such holder and other persons will be deemed to be a single selling holder, and any pro rata reduction with respect to such selling holder will be based upon the aggregate amount of Registrable Securities owned by all entities and individuals included in such selling holder, as defined in this sentence. No securities excluded from the underwriting by reason of the underwriter’s marketing limitation will be included in such registration. Upon delivery of a written request that Registrable Securities be included in the underwriting pursuant to Section 7.1.1 or 7.2.1.1, the holder thereof may not thereafter elect to withdraw therefrom without the written consent of the Company and the Majority Investors.

7.3.2. Other Actions. If and in each case when the Company is required to use its best efforts to effect a registration of any Registrable Securities as provided in this Section 7, the Company will take appropriate and customary actions in furtherance thereof, including, without limitation: (a) promptly filing with the Commission a registration statement and using reasonable efforts to cause such registration statement to become effective, (b) preparing and filing with the Commission such amendments and supplements to such registration statements as may be required to comply with the Securities Act and to keep such registration statement effective for a period not to exceed 270 days from the date of effectiveness or such earlier time as the Registrable Securities


Panther Stockholders_Agreement (Execution)		-19-

covered by such registration statement will have been disposed of in accordance with the intended method of distribution therefor or the expiration of the time when a prospectus relating to such registration is required to be delivered under the Securities Act, (c) use its best efforts to register or qualify such Registrable Securities under the state securities or “blue sky” laws of such jurisdictions as the sellers will reasonably request; provided, however, that the Company will not be obligated to file any general consent to service of process or to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it would not otherwise be so subject; and (d) otherwise cooperate reasonably with, and take such customary actions as may reasonably be requested by the holders of Registrable Securities in connection with, such registration.

7.3.3. Selection of Underwriters and Counsel. The underwriters and legal counsel to be retained in connection with any Public Offering will be selected by the Board or, in the case of an offering following a request therefor under Section 7.1.1, the Initiating Investors.

7.3.4. Lock-Up. Without the prior written consent of the underwriters managing any Public Offering, for a period beginning seven days immediately preceding and ending on the 90th day (or in the case of the Initial Public Offering, 180th day) following the effective date of the registration statement used in connection with such offering, no holder of Shares (whether or not a selling shareholder pursuant to such registration statement) will (a) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise Transfer, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for such Common Stock or (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Common Stock or any securities convertible into or exercisable or exchangeable for such Common Stock, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of such Common Stock or such other securities, in cash or otherwise; provided, however, that the foregoing restrictions will not apply to (i) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Initial Public Offering, (ii) Transfers to a Permitted Transferee of such holder in accordance with the terms of this Agreement or (iii) conversions of shares of Common Stock or other securities into other classes of Common Stock without change of holder.

7.4. Indemnification and Contribution.

7.4.1. Indemnities of the Company. In the event of any registration of any Registrable Securities or other debt or equity securities of the Company or any of its subsidiaries under the Securities Act pursuant to this Section 7 or otherwise, and in connection with any registration statement or any other disclosure document produced by or on behalf of the Company or any of its subsidiaries including, without limitation, reports required and other documents filed under the Exchange Act, and other documents pursuant to which any debt or equity securities of the Company or any of its subsidiaries


Panther Stockholders_Agreement (Execution)		-20-

are sold (whether or not for the account of the Company or its subsidiaries), the Company will, and hereby does, and will cause each of its subsidiaries, jointly and severally, to indemnify and hold harmless each seller of Registrable Securities, any Person who is or might be deemed to be a controlling Person of the Company or any of its subsidiaries within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, their respective direct and indirect partners, advisory board members, directors, officers, trustees, members and shareholders, and each other Person, if any, who controls any such seller or any such holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each such person being referred to herein as a “Covered Person”), against any losses, claims, damages or liabilities (or actions or proceedings in respect thereof), joint or several, to which such Covered Person may be or become subject under the Securities Act, the Exchange Act, any other securities or other law of any jurisdiction, the common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained or incorporated by reference in any registration statement under the Securities Act, any preliminary prospectus or final prospectus included therein, or any related summary prospectus, or any amendment or supplement thereto, or any document incorporated by reference therein, or any other such disclosure document (including without limitation reports and other documents filed under the Exchange Act and any document incorporated by reference therein) or other document or report, (ii) any 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 or any of its subsidiaries of any federal, state, foreign or common law rule or regulation applicable to the Company or any of its subsidiaries and relating to action or inaction in connection with any such registration, disclosure document or other document or report, and will reimburse such Covered Person for any legal or any other expenses incurred by it in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that neither the Company nor any of its subsidiaries will be liable to any Covered Person in any such case to the extent that any such loss, claim, damage, liability, action or proceeding arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement, incorporated document or other such disclosure document or other document or report, in reliance upon and in conformity with written information furnished to the Company or to any of its subsidiaries through an instrument duly executed by such Covered Person specifically stating that it is for use in the preparation thereof. The indemnities of the Company and of its subsidiaries contained in this Section 7.4.1 will remain in full force and effect regardless of any investigation made by or on behalf of such Covered Person and will survive any transfer of securities.

7.4.2. Indemnities to the Company. The Company and any of its subsidiaries may require, as a condition to including any securities in any registration statement filed pursuant to this Section 7, that the Company and any of its subsidiaries will have


Panther Stockholders_Agreement (Execution)		-21-

received, subject to the limitations set forth in Section 7.4.4, an undertaking satisfactory to it from the prospective seller of such securities, to indemnify and hold harmless the Company and any of its subsidiaries, each director of the Company or any of its subsidiaries, each officer of the Company or any of its subsidiaries who will sign such registration statement and each other Person (other than such seller), if any, who controls the Company and any of its subsidiaries within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each other prospective seller of such securities with respect to any statement in or omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus included therein, or any amendment or supplement thereto, or any other disclosure document (including, without limitation, reports and other documents filed under the Exchange Act or any document incorporated therein) or other document or report, if such statement or omission was made in reliance upon and in conformity with written information furnished to the Company or any of its subsidiaries through an instrument executed by such seller specifically stating that it is for use in the preparation of such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement, incorporated document or other document or report. Such indemnity will remain in full force and effect regardless of any investigation made by or on behalf of the Company, any of its subsidiaries or any such director, officer or controlling Person and will survive any transfer of securities.

7.4.3. Contribution. If the indemnification provided for in Sections 7.4.1 or 7.4.2 hereof is unavailable to a party that would have been entitled to indemnification pursuant to the foregoing provisions of this Section 7.4 (an “Indemnitee”) in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each party that would have been an indemnifying party thereunder will, in lieu of indemnifying such Indemnitee, subject to the limitation set forth in Section 7.4.4 contribute to the amount paid or payable by such Indemnitee as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative fault of such indemnifying party on the one hand and such Indemnitee on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof). The relative fault will 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 such indemnifying party or such Indemnitee and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties agree that it would not be just or equitable if contribution pursuant to this Section 7.4.3 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the preceding sentence. The amount paid or payable by a contributing party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 7.4.3 will include any legal or other expenses reasonably incurred by such Indemnitee in connection with investigating or defending any such action or claim. No Person guilty of fraudulent misrepresentation (within the meaning of Section 1l(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.


Panther Stockholders_Agreement (Execution)		-22-
