SELLING STOCKHOLDER

Pursuant to the Agreement and Plan of Merger (the “Merger Agreement”) among us, Element Merger Subsidiary, LLC (“Merger Subsidiary”), AIT Holding Company LLC (“AIT Holding”) and AIT, whereby Merger Subsidiary merged with and into AIT (the “Merger”), with AIT surviving as our subsidiary, we issued 4,500,000 shares of our common stock (the “Shares”) to AIT Holding on July 3, 2012 in a private placement exempt from registration by Section 4(2) of the Securities Act. In connection with the Merger Agreement, we entered into a registration rights agreement dated July 3, 2012 with AIT Holding (as amended on June 13, 2013, the “Registration Rights Agreement”). In accordance with the terms of the Registration Rights Agreement, this prospectus covers the resale of up to an aggregate of 4,500,000 of the Shares (the “Resale Shares”) by AIT Holding.

When we refer to the “Selling Stockholder” in this prospectus, we mean the person listed in the table below, as well as its donees, pledgees, assignees, transferees, distributees, successors and others who later hold the Resale Shares. This prospectus only covers resales of the Resale Shares by the selling stockholder named in the table below. Before any of such selling stockholder’s donees, pledgees, assignees, transferees, distributees, successors or others who later hold the Resale Shares can sell shares under this prospectus, we will file a prospectus supplement or post-effective amendment to update the selling stockholder information in this prospectus.

We agreed to use our reasonable best efforts to cause the registration statement of which this prospectus forms a part to be declared effective as soon as practicable and to remain continuously effective until the earlier of (i) one year following the date of effectiveness, subject to extension under certain circumstances, (ii) the date on which all the Resale Shares to which this prospectus relate have been sold and (iii) such date that all of the Resale Shares are freely transferable under Rule 144(b)(1) of the Securities Act (which, after July 3, 2013 in the case of AIT Holding or the HL Funds (defined below), shall be deemed to be three months following such date that the number of Resale Shares collectively held by AIT Holding and the HL Funds is less than ten percent (10.0%) of the aggregate number of shares of our common stock then issued and outstanding) (the “Effectiveness Period”). As used in this prospectus, the “HL Funds” means, collectively, HLHZ AIT Holding, L.L.C. (“HLHZ”), Houlihan Lokey, Inc. (“HL”), affiliates of HLHZ and/or HL and/or entities managed by HL.

The Effectiveness Period will be extended by the number of business days during which the registration statement of which this prospectus forms a part is not usable by the Selling Stockholder as set forth above and in the section “Plan of Distribution” below due to the occurrence of an event requiring: (a) the preparation of a supplement or amendment to this prospectus; (b) the issuance by the SEC of any stop order suspending the effectiveness of the registration statement of which this prospectus forms a part, or the initiation of any proceedings for such purpose; (c) the receipt by us of any notification with respect to the suspension of the qualification of the Resale Shares for sale in any jurisdiction, or the initiation of any proceeding for such purpose; or (d) changes in the prospectus or the registration statement of which this prospectus forms a part in order that they do not contain an untrue statement of a material fact and do not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. In addition, the Effectiveness Period will be extended by a number of calendar days equal to any period that we suspend the selling stockholder’s use of this prospectus under the Registration Rights Agreement because, in the judgment of our chief executive officer, the failure to suspend such use would: (1) materially interfere with a significant acquisition, corporate reorganization, or other similar transaction involving us; (2) require premature disclosure of material information that the we have a bona fide business purpose for preserving as confidential; or (3) render us unable to comply with requirements under the Securities Act or Exchange Act. We have agreed to pay all expenses incurred with respect to the registration of the Resale Shares (excluding any underwriting fees, discounts and commissions attributable to the sale of the Resale Shares) and certain legal expenses of the parties to the Registration Rights Agreement. The Registration Rights Agreement provides for cross-indemnification for certain liabilities arising under the Securities Act and contribution to payments which the other party may be required to make in that respect.

Table of Contents

All transfers of the Resale Shares by the Selling Stockholder, whether pursuant to this prospectus or otherwise, are subject to a lock-up and standstill agreement (the “Lock-Up and Standstill Agreement”) we entered into with AIT Holding, HLHZ and HL. Pursuant to the Lock-Up and Standstill Agreement, from January 3, 2013 through January 3, 2014, AIT Holding and certain permitted transferees may not sell or otherwise transfer, in any 90-day period, more than 25% of the Resale Shares, subject to certain exceptions. Permitted transfers under the Lock-Up and Standstill Agreement include distributions of Resale Shares by AIT Holding to the holders of its membership interests.

The following table sets forth information regarding the beneficial ownership of the Selling Stockholder as of the date hereof, including the name of the Selling Stockholder, the number and percentage of shares of our common stock beneficially owned by the Selling Stockholder and the number of shares and percentage of

shares beneficially owned by the Selling Stockholder after completion of the sale of the maximum number of Resale Shares that may be offered under this prospectus by such Selling Stockholder. The Selling Stockholder may, from time to time, offer and sell pursuant to this prospectus any or all of the Resale Shares registered for its account, and thus we cannot state with certainty the amount of shares that the Selling Stockholder will hold upon consummation of any such sales. Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to our shares of common stock. Generally, a person “beneficially owns” shares if the person has or shares with others the right to vote those shares or to dispose of them, or if the person has the right to acquire voting or disposition rights within 60 days. The percentage of shares beneficially owned prior to the offering is based on 28,427,516 shares of our common stock outstanding as of May 31, 2013. The information in the following table is based on the Selling Stockholder’s representations to us regarding its ownership as of the date of this prospectus.

The address of AIT Holding Company LLC is c/o Houlihan Lokey, 245 Park Avenue, New York, New York 10167.

(2) 

AIT Holding Company LLC beneficially owns directly 4,500,000 Shares, including 745,920 shares subject to an escrow agreement with Ultra Clean whereby stock certificates for such shares bear the name of an affiliate of the escrow agent as holder while AIT Holding Company LLC holds sole voting power over such shares. Eugene W. Bernosky, Gary F. Imdieke, Joseph A. Julian, Michael H. Mallinen, David A. Preiser, David R. Salemi and Leonard M. Tannenbaum are the Managers of AIT Holding Company LLC and share voting and dispositive power over the Shares held by AIT Holding Company LLC, and each disclaims beneficial ownership of the shares identified in this footnote except to the extent of his respective proportionate pecuniary interest in such shares. HLHZ AIT Holdings, L.L.C. owns a majority voting interest in AIT Holding Company LLC and may be deemed to beneficially own indirectly the Shares. AIT Holding Company LLC and HLHZ AIT Holdings, L.L.C. disclaim beneficial ownership of the Shares in excess of their pecuniary interest.

Additional Relationships and Transactions with Selling Stockholder

We entered into the Merger Agreement on May 18, 2012 with AIT Holding pursuant to which, on July 3, 2012, the closing date of the Merger, we paid AIT Holding cash of approximately $74.4 million (excluding certain working capital adjustments) and issued to AIT Holding 4,500,000 shares of our common stock as consideration for our acquisition of AIT. Pursuant to the Merger Agreement, in addition to the 745,920 escrowed Shares described below, approximately $2.7 million of the cash merger consideration was placed into a working capital escrow as security for post-closing adjustments to the merger consideration, and approximately $3.2 million of the cash merger consideration was placed in escrow as security for AIT Holding’s indemnification obligations during the escrow period. On October 10, 2012, approximately $2.0 million was released from the working capital escrow to us and the remainder was released to AIT Holding.

In accordance with a separate escrow agreement we entered into with AIT Holding and JPMorgan Chase Bank, NA, (“JPMorgan”) a total of 745,920 of the Shares are subject to an escrow and will be held by JPMorgan,

as escrow agent, as security for the indemnification obligations of AIT Holding under the Merger Agreement until October 3, 2013. AIT Holding has the right to vote the escrowed Shares, subject to the Lock-Up and Standstill Agreement, and to receive all dividends payable on the escrowed Shares. Any cash dividends or shares of our capital stock issuable in respect of or in exchange for any escrowed Shares, whether by way of share splits, dividends, or otherwise, will be held under the escrow agreement until the underlying escrowed Shares are released from escrow.

JPMorgan, as escrow agent, is permitted to transfer Shares held in the escrow account to us for the purpose of satisfying indemnification claims that may arise from time to time upon receipt of proper instructions and direction pursuant to the terms of the escrow agreement. Subject to the existence of any pending claims, shares retained in the escrow account as of the termination date for the escrow will be released to AIT Holding. If there are unresolved indemnification claims as of the termination date, JPMorgan will retain a number of shares in escrow having a value sufficient to cover the amount of such pending claims until such claims are resolved.

Under the Lock-Up and Standstill Agreement discussed above, AIT Holding and the HL Funds agreed, for a period of twenty-seven (27) months following the closing of the Merger (the “Standstill Period”), that they will not, whether individually or through any person acting on their behalf, or in concert with them, directly or indirectly, without our prior written consent, (i) acquire, agree to acquire, propose, seek or offer to acquire, any securities or assets of ours or any of our subsidiaries, (ii) enter, agree to enter, propose, seek or offer to enter into any merger, business combination, recapitalization, restructuring or other extraordinary transaction involving us or any of our subsidiaries, (iii) make, or in any way participate or engage in, any solicitation of proxies to vote any of our voting securities, (iv) form, join or in any way participate in a “group” (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) with respect to any of our voting securities, except any “group” deemed to exist solely as a result of the merger consideration paid to AIT Holding as part of the Merger Agreement, (v) otherwise act, alone or in concert with others, to seek to control or influence our management or policies, (vi) disclose any intention, plan or arrangement prohibited by, or inconsistent with, the foregoing, or (vii) advise, assist or encourage or enter into any discussions, negotiations, agreements or arrangements with any other persons in connection with the foregoing. In addition, during the Standstill Period, the HL Funds (nor any person acting on behalf of or in concert with such parties) will not, without our written consent, (x) request that we or any of our representatives, directly or indirectly, amend or waive these standstill obligations, or (y) take any action that might require us to make a public announcement regarding the possibility of a business combination, merger or other type of transaction described in this paragraph with such party. Additionally, for the duration of the Standstill Period, the HL Funds shall place and maintain our securities on HL’s “restricted securities” list, which securities shall be subject to HL’s restricted securities policy (the “Policy”). The HL Funds agreed that such Policy shall: (1) prohibit the HL Funds and their managers, officers, directors, partners and other employees from acquiring, directly or indirectly, our securities, or from transferring our securities, for their own account; (2) be strictly enforced by the HL Funds without waiver or exemption; and (3) not be amended or modified as it pertains to our securities.

The Lock-Up and Standstill Agreement provides that the HL Funds, as a full-service securities firm, may, from time to time, effect transactions for the account of their customers, hold positions in securities, provide investment banking and financing advice and otherwise conduct business in the ordinary course as a broker-dealer, investment adviser, block positioner or investment bank, and the Lock-Up and Standstill Agreement shall not be deemed or interpreted to prohibit, restrict, or otherwise limit such business activities.

Under the Registration Rights Agreement discussed above, we also agreed that, subject to the Lock-Up and Standstill Agreement, at the request of AIT Holding or a transferee holding at least 25% of the Shares, we can be required (but only once) to effect a registration statement registering the securities held by such requesting party at any time from January 3, 2013 through July 3, 2016. In addition, if we propose to register any of our securities, other than a registration on form S-8 or S-4 or successor forms of these forms, whether or not such registration is for our own account, AIT Holding and certain of AIT Holding permitted transferees may participate in such registration, subject to customary “cut back” limitations. We and the stockholders selling securities under a

registration statement pursuant to the Registration Rights Agreement will be required to enter into customary indemnification and contribution arrangements with respect to each such registration statement.

One of AIT’s current employees is a member and a manager of AIT Holding and thus may receive a portion of any consideration received by AIT Holding pursuant to the offer and sale of the Resale Shares pursuant to AIT Holding’s membership agreement. No member of AIT Holding is a director or officer of Ultra Clean.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock is based upon our certificate of incorporation (“Certificate of Incorporation”), our bylaws (“Bylaws”) and applicable provisions of law. We have summarized certain portions of the Certificate of Incorporation and Bylaws below. This information does not purport to be complete and is subject in all respects to the applicable provisions of our Certificate of Incorporation and Bylaws, which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part. You should read the Certificate of Incorporation and Bylaws for the provisions that are important to you.

Authorized Capital Stock

Our Certificate of Incorporation authorizes us to issue 90,000,000 shares of common stock, par value $0.001 per share, and 10,000,000 shares of preferred stock, par value $0.001 per share.

Common Stock

As of May 31, 2013, there were 28,427,516 shares of common stock outstanding and seven stockholders of record. The holders of common stock are entitled to one vote per share on all matters to be voted upon by the stockholders. Subject to preferences that may be applicable to any outstanding preferred stock, the holders of common stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by our board of directors out of funds legally available therefor. In the event of the liquidation, dissolution or winding up of Ultra Clean, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are fully paid and non-assessable.

Preferred stock

Our board of directors is authorized, subject to any limitations imposed by law, without stockholder approval, from time to time to issue up to 10,000,000 shares of preferred stock in one or more series, each series to have rights and preferences, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, as our board of directors may determine. The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire, a majority of our voting stock outstanding. We have no shares of preferred stock outstanding, and we have no present plans to issue any shares of preferred stock.

Registration Rights

We entered into the Registration Rights Agreement at the closing of our acquisition of AIT. The Registration Rights Agreement provides that, under certain circumstances and subject to the Lock-Up and Standstill Agreement, at the request of AIT Holding or a transferee holding at least 25% of the shares of our common stock issued in the Merger, we can be required (but only once) to effect a registration statement registering the securities held by AIT Holding or such transferees at any time from January 3, 2013 through the fourth anniversary of the closing of the merger.

In addition, if we propose to register any of our securities, other than a registration on form S-8 or S-4 or successor forms of these forms, whether or not such registration is for our own account, AIT Holding and certain of its permitted transferees may participate in such registration, subject to customary “cut back” limitations.

Further, subject to the terms of the Lock-Up and Standstill Agreement described in the section “Selling Stockholder” of this prospectus, we were required pursuant to the Registration Rights Agreement to file with the SEC the registration statement of which this prospectus is a part, covering the resale of Resale Shares. See “Selling Stockholder” above.

Table of Contents

We and the stockholders selling securities under a registration statement pursuant to the Registration Rights Agreement may be required to enter into customary indemnification and contribution arrangements with respect to each such registration statement.

Certain Provision of Our Certificate of Incorporation and Bylaws

Our Bylaws vest the power to call special meetings of stockholders in our chairman of the board and our board of directors. Stockholders are permitted under our Certificate of Incorporation to act by written consent in lieu of a meeting.

To be properly brought before an annual meeting of stockholders, any stockholder proposal or nomination for the board of directors must be delivered to our secretary not less than 90 days nor more than 120 days prior to the first anniversary of the prior year’s annual meeting; provided, however, that in the event that the date of the annual meeting is advanced more than 30 days prior to such anniversary date or delayed more than 70 days after such anniversary date, then to be timely such notice must be received by us no earlier than 120 days prior to such annual meeting and no later than the later of 70 days prior to the day of the meeting or the 10th day following the day on which public announcement of the date of the meeting was first made by us. Such notice must contain information specified in the Bylaws as to the director nominee or proposal of other business, information about the stockholder making the nomination or proposal and the beneficial owner, if any, on behalf of whom the nomination or proposal is made, including name and address, class and number of shares owned, and representations regarding the intention to make such a proposal or nomination and to solicit proxies in support of it.

Certain Anti-Takeover Effects of Delaware Law

We are subject to Section 203 of the Delaware General Corporation Law (“Section 203”). In general, Section 203 prohibits a publicly held Delaware corporation from engaging in various “business combination” transactions with any interested stockholder for a period of three years following the date of the transactions in which the person became an interested stockholder, unless:

 

   

the transaction is approved by the board of directors prior to the date the interested stockholder obtained such status;

 

   

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or

 

   

on or subsequent to such date the business combination is approved by the board and authorized at an annual or special meeting of stockholders by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder.

A “business combination” is defined to include mergers, asset sales, and other transactions resulting in financial benefit to a stockholder. In general, an “interested stockholder” is a person who, together with affiliates and associates, owns (or within three years, did own) 15% or more of a corporation’s voting stock.

The statute could prohibit or delay mergers or other takeover or change in control attempts with respect to us and, accordingly, may discourage attempts to acquire us even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.

Listing

Our common stock is listed on the Nasdaq Global Select Market under the symbol “UCTT”.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Wells Fargo Shareowner Services.

PLAN OF DISTRIBUTION

We are registering the Resale Shares covered by this prospectus to permit the Selling Stockholder to conduct public secondary trading of these Resale Shares from time to time after the date of this prospectus. We will not receive any of the proceeds of the sale of the Resale Shares offered by this prospectus. The aggregate proceeds to the Selling Stockholder from the sale of the Resale Shares will be the purchase price of the Resale Shares less any discounts and commissions. We will not pay any brokers’ or underwriters’ discounts and commissions in connection with the registration and sale of the Resale Shares covered by this prospectus. The Selling Stockholder reserves the right to accept and, together with its respective agents, to reject, any proposed purchases of Resale Shares to be made directly or through agents.

The Lock-Up and Standstill Agreement permits distributions of Resale Shares by AIT Holding to the holders of its membership interests, provided that such transferee will be subject to the Lock-Up and Standstill Agreement. Before any member receiving Resale Shares can sell shares under this prospectus, we will file a prospectus supplement or post-effective amendment to update the selling stockholder information in this prospectus.

The Resale Shares offered by this prospectus may be sold from time to time to purchasers:

 

   

directly by the Selling Stockholder, or

 

   

through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, commissions or agent’s commissions from the Selling Stockholder or the purchasers of the Shares. These discounts, concessions, or commissions may be in excess of those customary in the types of transaction involved.

Any underwriters, broker-dealers or agents who participate in the sale or distribution of the Resale Shares may be deemed to be “underwriters” within the meaning of the Securities Act. As a result, any discounts, commissions or concessions received by any such broker-dealer or agents who are deemed to be underwriters will be deemed to be underwriting discounts and commissions under the Securities Act. Underwriters are subject to the prospectus delivery requirements of the Securities Act and may be subject to certain statutory liabilities, including, but not limited to, those relating to Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the Exchange Act. We will make copies of this prospectus available to the Selling Stockholder for the purpose of satisfying the prospectus delivery requirements of the Securities Act. To our knowledge, the Selling Stockholder is not a broker-dealer or an affiliate of a broker dealer, nor would it otherwise be deemed to be an “underwriter” within the meaning of Section 2(11) of the Securities Act. To our knowledge, there are currently no plans, arrangements or understandings between the Selling Stockholder and any underwriter, broker-dealer or agent regarding the sale of the Resale Shares by the Selling Stockholder.

The Resale Shares may be sold in one or more transactions at:

 

   

fixed prices;

 

   

prevailing market prices at the time of sale;

 

   

prices related to such prevailing market prices;

 

   

varying prices determined at the time of sale; or

 

   

negotiated prices.

These sales may be effected in one or more transactions:

 

   

on any national securities exchange or quotation service on which the Resale Shares may be listed or quoted at the time of sale, including the Nasdaq Global Select Market;

 

   

in the over-the-counter market;

Table of Contents
   

in transactions otherwise than on such exchanges or services or in the over-the-counter market;

 

   

through the writing of options (including the issuance by the Selling Stockholder of derivative securities), whether the options or such other derivative securities are listed on an options exchange or otherwise;

 

   

through the settlement of short sales;

 

   

any other method permitted by applicable law; or

 

   

through any combination of the foregoing.

These transactions may include block transactions or crosses. Crosses are transactions in which the same broker acts as an agent on both sides of the trade. In connection with the sales of the Shares, the Selling Stockholder may enter into hedging transactions with broker-dealers or other financial institutions that in turn may:

 

   

engage in short sales of the Resale Shares in the course of hedging their positions;

 

   

sell the Resale Shares short and deliver the Resale Shares to close out short positions;

 

   

loan or pledge the Resale Shares to broker-dealers or other financial institutions that in turn may sell the Resale Shares;

 

   

enter into option or other transactions with broker-dealers or other financial institutions that require the delivery to the broker-dealer or other financial institution of the Resale Shares, which the broker-dealer or other financial institution may resell under the prospectus; or

 

   

enter into transactions in which a broker-dealer makes purchases as a principal for resale for its own account or through other types of transactions.

A short sale of Resale Shares by a broker-dealer, financial institution or the Selling Stockholder would involve the sale of such Resale Shares that are not owned, and therefore must be borrowed, in order to make delivery of the security in connection with such sale. In connection with a short sale of Resale Shares, a broker-dealer, financial institution or the Selling Stockholder may purchase shares on the open market to cover positions created by short sales. In determining the source of the shares to close out such short positions, the broker-dealer, financial institution or Selling Stockholder may consider, among other things, the price of shares available for purchase in the open market.

At the time a particular offering of the Resale Shares is made, a prospectus supplement, if required, will be distributed, which will set forth the name of the Selling Stockholder, the aggregate amount of Resale Shares being offered and the terms of the offering, including, to the extent required, (1) the name or names of any underwriters, broker-dealers or agents, (2) any discounts, commissions and other terms constituting compensation from the Selling Stockholder and (3) any discounts, commissions or concessions allowed or reallowed to be paid to broker-dealers. We may suspend the sale of Resale Shares by the Selling Stockholder pursuant to this prospectus for certain periods of time for certain reasons, including if the prospectus is required to be supplemented or amended to include additional material information.

Pursuant to a requirement by the Financial Industry Regulatory Authority, Inc. (“FINRA”), the maximum commission or discount to be received by any FINRA member or independent broker-dealer may not be greater than 8% of the gross proceeds received by the Selling Stockholder for the sale of any Resale Shares being offered by this prospectus.

The Resale Shares are listed on the Nasdaq Global Select Market under the symbol “UCTT.”

The Selling Stockholder will act independently of us in making decisions with respect to the timing, manner, and size of each resale or other transfer. There can be no assurance that the Selling Stockholder will sell any or all of the Resale Shares under this prospectus. Further, we cannot assure you that the Selling Stockholder

will not transfer, distribute, devise or gift the Resale Shares by other means not described in this prospectus. In addition, any Resale Shares covered by this prospectus that qualify for sale under Rule 144 of the Securities Act may be sold under Rule 144 rather than under this prospectus. The Resale Shares may be sold in some states only through registered or licensed brokers or dealers. In addition, in some states the Resale Shares may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification is available and complied with.

The Selling Stockholder and any other person participating in the sale of the Resale Shares will be subject to the Exchange Act. The Exchange Act rules include, without limitation, Regulation M, which may limit the timing of purchases and sales of any of the Resale Shares by the Selling Stockholder and any other person. In addition, Regulation M may restrict the ability of any person engaged in the distribution of the Resale Shares to engage in market-making activities with respect to the particular Resale Shares being distributed. This may affect the marketability of the Resale Shares and the ability of any person or entity to engage in market-making activities with respect to the Resale Shares.

In the Registration Rights Agreement, we have agreed to indemnify or provide contribution to the Selling Stockholder against certain liabilities, including certain liabilities under the Securities Act. In addition, we have agreed to pay all of the expenses incidental to the registration of the Resale Shares to the public, including the payment of federal securities law and state blue sky registration fees, except that we will not bear any underwriting discounts or commissions or transfer taxes relating to the sale of the Resale Shares. The Selling Stockholder has agreed to indemnify us in certain circumstances against certain liabilities, including certain liabilities under the Securities Act. Both we and the Selling Stockholder may indemnify any underwriter that participates in transactions involving the sale of the Resale Shares against certain liabilities, including liabilities arising under the Securities Act.
