4. Industrea Representations and Warranties. Each of Industrea and Newco represents and warrants to Subscriber that:

a. Each of Industrea and Newco (i) is duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, (ii) has the requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted and to enter into and perform its obligations under this Subscription Agreement and the Merger Agreement, and (iii) is duly licensed or qualified to conduct its business and, if applicable, is in good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation) in which the conduct of its business or the ownership of its properties or assets requires such license or qualification, except, with respect to the foregoing clause (iii), where the failure to be in good standing would not reasonably be expected to have an Industrea Material Adverse Effect. For purposes of this Subscription Agreement, an “Industrea Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to Industrea that, individually or in the aggregate, has a material adverse effect on the business, financial condition or results of operations of Industrea or Newco, taken as a whole.

b. The Shares and the Conversion Shares (as defined below), when issued and delivered to Subscriber against full payment therefor in accordance with the terms of this Subscription Agreement, will be validly issued, fully paid and non-assessable and will not have been issued in violation of any preemptive or similar rights created under Newco’s certificate of incorporation or the Delaware General Corporation Law.

c. This Subscription Agreement has been duly executed and delivered by Industrea and Newco, and assuming the due authorization, execution and delivery of the same by Subscriber, this Agreement shall constitute the valid and legally binding obligation of Industrea and Newco, enforceable against Industrea and Newco in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

d. The execution and delivery of this Subscription Agreement, the issuance and sale of the Shares and the compliance by Industrea and Newco with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will be done in accordance with the rules and regulations of Nasdaq (as defined below) and will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of Industrea or Newco pursuant to the terms of: (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Industrea or Newco is a party or by which Industrea or Newco is bound or to which any of the property or assets of Industrea or Newco is subject; (ii) the organizational documents of Industrea or Newco; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Industrea or Newco or any of their properties that, in the case of clauses (i) and (iii), would reasonably be expected to have an Industrea Material Adverse Effect or have a material adverse effect on Industrea’s or Newco’s ability to consummate the transactions contemplated hereby, including the valid issuance and sale of the Shares.

e. Industrea and Newco are not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including The Nasdaq Stock Market (“Nasdaq”)) or other person in connection with the execution, delivery and performance of this Subscription Agreement (including, without limitation, the issuance of the Shares), other than: (i) filing the Certificate with the Secretary of State of the State of Delaware; (ii) filings required by applicable state securities laws; (iii) the filing of a Notice of Exempt Offering of Securities on Form D with the Commission pursuant to Regulation D under the Securities Act (“Regulation D”); (iv) the filings required in accordance with Section 9(b) of this Subscription Agreement; (v) those required by Nasdaq, including with respect to obtaining shareholder approval; (vi) those required to consummate the Transaction as provided under the Merger Agreement; and (vii) the failure of which to obtain would not be reasonably likely to have an Industrea Material Adverse Effect or have a material adverse effect on Industrea’s or Newco’s ability to consummate the transactions contemplated hereby, including the valid issuance and sale of the Shares.

f. As of the date hereof, the authorized share capital of Industrea consists of 200,000,000 shares of Class A Common Stock, 20,000,000 shares of Class B common stock, par value $0.0001 per share (“Class B Common Stock” and together with the Class A Common Stock, “Common Stock”), and 1,000,000 shares of preferred stock, par value $0.0001 per share (“Preferred Stock”). As of the date hereof: (i) 23,000,000 shares of Class A Common Stock, 5,750,000 shares of Class B Common Stock and no shares of Preferred Stock are issued and outstanding; (ii) 34,100,000 warrants, each exercisable to purchase one share of Class A Common Stock at $11.50 per share (“Warrants”), are issued and outstanding, including 11,100,000 private placement warrants; and (iii) no shares of Common Stock are subject to issuance upon exercise of outstanding options. No Warrants are exercisable on or prior to the Closing. All (i) issued and outstanding shares of Common Stock have been duly authorized and validly issued, are fully paid and are non-assessable and are not subject to preemptive rights and (ii) outstanding Warrants have been duly authorized and validly issued, are fully paid and are not subject to preemptive rights. Except as set forth above and pursuant to the Other Subscription Agreements and the Merger Agreement and the agreements attached as exhibits thereto, there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from Industrea or Newco any shares of Common Stock or other equity interests in Industrea or Newco (collectively, “Equity Interests”) or securities convertible into or exchangeable or exercisable for Equity Interests. As of the date hereof, other than with respect to Newco, Concrete Parent, Concrete Merger Sub and Industrea Merger Sub, Industrea has no subsidiaries and does not own, directly or indirectly, interests or investments (whether equity or debt) in any person, whether incorporated or unincorporated. There are not any stockholder agreements, voting trusts or other agreements or understandings to which Industrea or Newco is a party or by which either is bound relating to the voting of any Equity Interests, other than (A) the letter agreements entered into by Industrea in connection with Industrea’s initial public offering on August 1, 2017 pursuant to which Industrea Alexandria LLC and Industrea’s executive officers and independent directors agreed to vote in favor of any proposed Business Combination (as defined therein), which includes the Transaction, and (B) as contemplated by the Merger Agreement.

g. Except for such matters as have not had and would not be reasonably likely to have an Industrea Material Adverse Effect or have a material adverse effect on Industrea’s or Newco’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Shares, as of the date hereof, there is no (i) suit, action, proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of Industrea or Newco, threatened against Industrea or Newco or (ii) judgment, decree, injunction, ruling or order of any governmental authority or arbitrator outstanding against Industrea or Newco.

h. The issued and outstanding shares of Class A Common Stock are registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are listed for trading on Nasdaq under the symbol “INDU.” There is no suit, action, proceeding or investigation pending or, to the knowledge of Industrea, threatened against Industrea by Nasdaq or the Commission with respect to any intention by such entity to deregister the shares of Class A Common Stock or prohibit or terminate the listing of the shares of Class A Common Stock on Nasdaq. Industrea has taken no action that is designed to terminate the registration of the shares of Class A Common Stock under the Exchange Act.

i. Upon consummation of the Transaction, the issued and outstanding shares of Newco Common Stock will be registered pursuant to Section 12(b) of the Exchange Act, and will be approved for listing, subject only to official notice of the issuance, on Nasdaq under the symbol “BBCP”.

j. Assuming the accuracy of Subscriber’s representations and warranties set forth in Section 5 of this Subscription Agreement, no registration under the Securities Act is required for the offer and sale of the Shares by Newco to Subscriber.

k. Neither Industrea nor Newco nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with any offer or sale of the Shares.

l. Neither Industrea nor Newco has paid, nor is obligated to pay, any brokerage, finder’s or other fee or commission in connection with Newco’s issuance and sale of the Shares, other than fees to the Placement Agent.

5. Subscriber Representations and Warranties. Subscriber represents and warrants to Industrea and Newco that:

a. Subscriber (i) is duly organized, validly existing and in good standing under the Laws of its jurisdiction of incorporation and (ii) has the requisite power and authority to enter into and perform its obligations under this Subscription Agreement.

b. This Subscription Agreement has been duly executed and delivered by Subscriber, and assuming the due authorization, execution and delivery of the same by Industrea and Newco, this Agreement shall constitute the valid and legally binding obligation of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

c. The execution and delivery of this Subscription Agreement, the purchase of the Shares and the compliance by Subscriber with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of Subscriber or the funds and/or accounts represented by Subscriber that will purchase the Shares (collectively, the “Purchasing Funds”) pursuant to the terms of: (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Subscriber is a party or by which Subscriber is bound or to which any of the property or assets of Subscriber is subject; (ii) the organizational documents of Subscriber; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Subscriber or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Subscriber Material Adverse Effect. For purposes of this Subscription Agreement, a “Subscriber Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to Subscriber that would reasonably be expected to have a material adverse effect on Subscriber’s ability to consummate the transactions contemplated hereby, including the purchase of the Shares.

d. Each of the Purchasing Funds (i) is an institutional “accredited investor” (within the meaning of Rule 501(a) under the Securities Act) satisfying the applicable requirements set forth on Schedule A, (ii) is acquiring the Shares only for its own account and not for the account of others, and (iii) is not acquiring the Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and shall provide the requested information on Annex B following the signature page hereto). Subscriber is not an entity formed for the specific purpose of acquiring the Shares.

e. Subscriber understands that the Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Shares and any shares of Class A Common Stock into which the Shares may be converted (the “Conversion Shares”) have not been registered under the Securities Act. Subscriber understands that the Shares and the Conversion Shares may not be resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to Newco, or (ii) pursuant to an applicable exemption from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with any applicable securities laws of the states and other jurisdictions of the United States, and that any certificates or book-entry position representing the Shares and the Conversion Shares shall contain a legend to such effect. Subscriber understands and agrees that the Shares and the Conversion Shares will be subject to transfer restrictions and, as a result of these transfer restrictions, Subscriber may not be able to readily resell the Shares or the Conversion Shares and may be required to bear the financial risk of an investment in the Shares and the Conversion Shares for an indefinite period of time. Subscriber understands that it has been advised to consult legal counsel prior to making any offer, resale, pledge or transfer of any of the Shares or the Conversion Shares.

f. Subscriber understands and agrees that each of the Purchasing Funds is purchasing the Shares directly from Newco. Subscriber further acknowledges that there have not been, and Subscriber is not relying on, any representations, warranties, covenants and agreements made to Subscriber by Newco, any other party to the Transaction or any other person or entity, expressly or by implication, other than those representations, warranties, covenants and agreements of Newco included in this Subscription Agreement.

g. Each of the Purchasing Funds’ acquisition and holding of the Shares or the Conversion Shares will not constitute or result in a non-exempt prohibited transaction under Section 406 of the Employee Retirement Income Security Act of 1974, as amended, Section 4975 of the Internal Revenue Code of 1986, as amended, or any applicable similar law.

h. In making its decision to enter into this Subscription Agreement, Subscriber has relied solely upon independent investigation made by Subscriber. Subscriber acknowledges and agrees that Subscriber has received such information as Subscriber deems necessary in order to make an investment decision with respect to the Shares, including with respect to Newco and the Transaction (including the company to be acquired in the Transaction and its respective subsidiaries). Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as Subscriber and such undersigned’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Shares. Subscriber acknowledges and agrees that neither B. Riley FBR, Inc., acting as placement agent to Industrea and Newco (the “Placement Agent”), nor any affiliate of the Placement Agent has provided Subscriber with any information or advice with respect to the Shares nor is such information or advice necessary or desired. Neither the Placement Agent nor any of its affiliates has made or makes any representation as to Newco or the quality of the Shares and the Placement Agent and any affiliate may have acquired non-public information with respect to Newco which Subscriber agrees need not be provided to it. In connection with the issuance of the Shares to Subscriber, neither the Placement Agent nor any of its affiliates has acted as a financial advisor or fiduciary to Subscriber.

i. Subscriber became aware of this offering of the Shares solely by means of direct contact between Subscriber and Industrea and Newco or by means of contact from the Placement Agent, and the Shares were offered to Subscriber solely by direct contact between Subscriber and Industrea and Newco or by contact between Subscriber and the Placement Agent. Subscriber did not become aware of this offering of the Shares, nor were the Shares offered to Subscriber, by any other means. Subscriber acknowledges that Newco represents and warrants that the Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act or any state securities laws.

j. Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Shares. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Shares, and Subscriber has sought such accounting, legal and tax advice as Subscriber has considered necessary to make an informed investment decision.

k. Subscriber has adequately analyzed and fully considered the risks of an investment in the Shares and determined that the Shares are a suitable investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in Newco. Subscriber acknowledges specifically that a possibility of total loss exists.

l. Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Shares or made any findings or determination as to the fairness of this investment.

m. Neither Subscriber nor any of the Purchasing Funds is (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any Executive Order issued by the President of the United States and administered by OFAC (“OFAC List”), or a person or entity prohibited by any OFAC sanctions program, (ii) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515, or (iii) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank. Subscriber agrees to provide law enforcement agencies, if requested thereby, such records as required by applicable law, provided that Subscriber is permitted to do so under applicable law. Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. Subscriber also represents that, to the extent required, it maintains policies and procedures reasonably designed for the screening of its investors against the OFAC sanctions programs, including the OFAC List. Subscriber further represents and warrants that, to the extent required, it maintains policies and procedures reasonably designed to ensure that the funds held by the Purchasing Funds and used to purchase the Shares were legally derived.

n. Subscriber and its affiliates do not have, and during the 30-day period immediately prior hereto such Subscriber and its affiliates have not entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under the Exchange Act or short sale positions with respect to the securities of Newco. In addition, the Subscriber shall comply with all applicable provisions of Regulation M promulgated under the Securities Act.

o. Subscriber acknowledges and agrees that the certificate or book-entry position representing the Shares will bear or reflect, as applicable, a legend substantially similar to the following:

“THIS SECURITY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF CONCRETE PUMPING HOLDINGS ACQUISITION CORP. THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) PURSUANT TO ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, (II) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (III) TO CONCRETE PUMPING HOLDINGS ACQUISITION CORP., IN EACH OF CASES (I) THROUGH (III) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL NOTIFY ANY SUBSEQUENT PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE. CONCRETE PUMPING HOLDINGS ACQUISITION CORP. MAY REQUIRE THE DELIVERY OF A WRITTEN OPINION OF COUNSEL, CERTIFICATIONS AND/OR ANY OTHER INFORMATION IT REASONABLY REQUIRES TO CONFIRM THE SECURITIES ACT EXEMPTION FOR SUCH TRANSACTION.”

6. Registration Rights.

a. Newco agrees that, within ninety (90) calendar days after the Closing (the “Filing Deadline”), Newco will, at its sole cost and expense, file with the Commission a registration statement (the “Post-Closing Registration Statement”) registering the resale of the Conversion Shares, and Newco shall use its commercially reasonable efforts to have the Post-Closing Registration Statement declared effective within sixty (60) days after the Filing Deadline (the “Effectiveness Deadline”); provided, that the Effectiveness Deadline shall be extended to one hundred twenty (120) days after the Filing Deadline if the Post-Closing Registration Statement is “reviewed” by, and Newco receives comments from, the Commission; provided, however, that Newco’s obligations to include the Conversion Shares in the Post-Closing Registration Statement are contingent upon Subscriber furnishing in writing to Newco such information regarding Subscriber, the securities of Newco held by Subscriber and the intended method of disposition of the Conversion Shares as shall be reasonably requested by Newco to effect the registration of the Conversion Shares, and shall execute such documents in connection with such registration as Newco may reasonably request that are customary of a selling stockholder in similar situations. Newco will use its commercially reasonable efforts to maintain the continuous effectiveness of the Post-Closing Registration Statement until the earlier of (a) the date on which such securities may be resold without volume or manner of sale limitations pursuant to Rule 144 promulgated under the Securities Act and (b) the date on which Subscriber has notified Newco that all such registrable securities have actually been sold.

b. If at any time Newco proposes to file with the Commission a registration statement or prospectus supplement relating to an underwritten public offering for the account of selling stockholders who have registration rights under the Stockholders Agreement (as defined below), then Newco shall provide Subscriber with at least twenty (20) days advance written notice of such registration or filing and offer to include in such underwritten offering such number of Conversion Shares as may be requested to be included therein by Subscriber in writing within five (5) days of Subscriber’s receipt of such notice. If the underwriter(s) for any such offering advise Newco that marketing factors require a limitation on the number of securities that may be included in such offering, the number of Conversion Shares to be so included may be reduced on the terms set forth in the Stockholders Agreement. Newco shall not be required to include Conversion Shares in more than three (3) underwritten public offerings pursuant to this Section 6(b); provided that any offering in which Conversion Shares were not included (due to the previous sentence or otherwise) or in which Subscriber elected not to participate shall not count towards this limitation. For purposes of this Section 6(b), “Stockholders Agreement” means the Stockholders Agreement to be entered into at the Closing among Newco, Industrea and the parties signatory thereto. Notwithstanding the foregoing, Subscriber shall not have any rights to include its Conversion Shares in the underwritten offering that PGP Investors, LLC and its affiliates (“Peninsula”) are entitled to cause the Company to effect with respect to the shares of Common Stock, if any, to be issued to Peninsula in excess of 882,353 shares, in connection with the transactions contemplated by the Merger Agreement.

c. Newco shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless Subscriber (to the extent a seller under the Post-Closing Registration Statement), the officers, directors, agents, partners, members, managers, stockholders, affiliates, employees and investment advisers of each of them, each person who controls Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, managers, stockholders, agents, affiliates, employees and investment advisers of each such controlling person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Post-Closing Registration Statement, any prospectus included in the Post-Closing Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (ii) any violation or alleged violation by Newco of the Securities Act, the Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 6, except to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding Subscriber furnished in writing to Newco by Subscriber expressly for use therein. Newco shall notify Subscriber promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 6 of which Newco is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Shares by Subscriber.

d.

Notwithstanding anything to the contrary, the foregoing waiver shall not preclude Subscriber (or any of its affiliates) from redeeming any shares of Class A Common Stock included in the units sold in Industrea’s initial public offering held by Subscriber (or any of its affiliates) for a pro rata portion of the Trust Account in connection with the Transaction or enforcing its rights in respect thereof.

ANNEX A

Term Sheet

INDUSTREA ACQUISITION CORP.

SUMMARY OF PROPOSED TERMS FOR

ZERO-DIVIDEND CONVERTIBLE PERPETUAL PREFERRED STOCK

This Term Sheet outlines the principal terms with respect to a proposed private sale by Concrete Pumping Holdings Acquisition Corp., a Delaware corporation (the “Company”), of Series A Zero-Dividend Convertible Perpetual Preferred Stock of the Company to [ ] (“Investor”) to occur concurrently with the Company’s proposed business combination with Concrete Pumping Holdings, Inc. (“CPH”). This Term Sheet is intended solely as a basis for further discussion and is not intended to be and does not constitute a legally binding obligation.

Issuer	Concrete Pumping Holdings Acquisition Corp., a Delaware corporation
Aggregate Offering Amount	$25,000,000 (the “Investment Amount”).
Security Offered	The Company’s Series A Zero-Dividend Convertible Perpetual Preferred Stock, par value $0.0001 per share (the “Preferred Stock”).
Number of Shares Offered	2,450,980 shares
Issue Date	Concurrent with the closing of the Business Combination (described below).
Dividends	None.
Liquidation Preference	The liquidation preference of the Preferred Stock will be (a) the Investment Amount plus (b) an additional cumulative amount that will accrue at an annual rate of 7.0% (as may be adjusted as described in “Covenants” below, the “Additional Liquidation Preference Rate”) beginning on the Issue Date through the date of calculation, expressed as a per-share amount (the “Liquidation Preference”). In the event of any liquidation, dissolution or winding up of the Company or any consolidation, merger or sale of all or substantially all of the assets of the Company, each holder of the Preferred Stock will be entitled to receive an amount equal to the Liquidation Preference per share with respect to each share of Preferred Stock held by such holder. The Preferred Stock will rank senior in priority and will have a senior liquidation preference to the Common Stock and any other existing class of equity securities of the Company, and no new class of preferred stock bearing a liquidation preference and/or rights to dividends pari passu with, or senior to, the Preferred Stock may be created without the consent of the holders of the Preferred Stock.

Conversion Ratio; Anti-Dilution

The Preferred Stock shall be convertible into shares of the Company’s Common Stock at a 1:1 conversion ratio (as may be adjusted as described below, the “Conversion Ratio”).

The Conversion Ratio (and the number of shares of Common Stock into which the Preferred Stock may be converted (the “Conversion Shares”)) will be equitably adjusted upon the occurrence of standard anti-dilution events, including:

· any stock split or subdivision of the Common Stock (in which case the number of Conversion Shares will be increased proportionately and the Conversion Ratio decreased proportionately); and

· any reverse stock split or consolidation of the Common Stock (in which case the number of Conversion Shares will be decreased proportionately and the Conversion Ratio increased proportionately).

Conversion at the Option of the Holder

Each holder of Preferred Stock will have the right to convert, at its option, all of the shares of Preferred Stock that it holds into shares of Common Stock at the Conversion Ratio at any time on or following the date that is six calendar months following the Issue Date. The total number of shares of Common Stock into which the Preferred Stock may be converted will be determined by multiplying (a) the number of shares of Preferred Stock being converted by (b) the Conversion Ratio (as adjusted).

Conversion at the Option of the Company

The Company shall, at its option, have the right to cause the conversion of all outstanding shares of Preferred Stock into shares of Common Stock at any time following such time as the VWAP per share of the Common Stock is equal or greater than $13.00 (the “Mandatory Conversion Threshold”) for 30 consecutive days. The total number of shares of Common Stock into which the Preferred Stock may be converted will be determined by multiplying (x) the number of shares of Preferred Stock being converted by (y) the Conversion Ratio (as adjusted). The Mandatory Conversion Threshold will be equitably adjusted in the event of a stock split, subdivision or similar event affecting the Common Stock.

Redemption	At any time on or following the date that is four years following the Issue Date, the Company may, at its option, redeem all or part of any outstanding shares of Preferred Stock at a redemption price equal to the then-applicable Liquidation Preference. For the avoidance of doubt, such redemption shall be effectuated via written notice at least 15 business days prior to the redemption date, and in the interim the holders of the Preferred Stock shall have the option, but not the obligation, to convert some or all of their shares of Preferred Stock into Common Stock prior to the redemption date.

Covenants	No financial covenants. In the event that the Company incurs any new debt (other than borrowings under the term loan and revolving credit facilities) that ranks junior to the term loan and revolving credit facilities (“Junior Debt”), then to the extent that, after giving effect to the incurrence of such additional Junior Debt, the pro forma Total Leverage Ratio (as defined in the term loan credit agreement) shall exceed 5x EBITDA, the Additional Liquidation Preference Rate (a) shall be increased by 2.0% beginning on the first day of the first calendar quarter following the incurrence of such additional Junior Debt and (b) thereafter, shall be decreased by 2.0% beginning on the first day of the first calendar quarter following such time as the pro forma Total Leverage Ratio no longer exceeds 5x EBITDA. Notwithstanding the foregoing, the Company will be permitted to draw on the revolving credit facility and any incremental facilities permitted under the term loan credit agreement to the fullest extent permitted by those documents regardless of the impact that such additional borrowings may have on the Total Leverage Ratio.
Voting Rights	Except as otherwise required by law, the affirmative vote of holders of a majority of the outstanding shares of Preferred Stock, voting as a class, shall be required to approve any change or alteration in the rights, preferences or privileges of the Preferred Stock. In addition, holders of Preferred Stock shall vote together with the holders of Common Stock, as a single class, upon any matter submitted to the common stockholders for a vote and shall have that number of votes per share as is equal to the number of whole shares of Common Stock into which each share of Preferred Stock held by such holder could be converted on the record date established for such purpose. Notwithstanding the foregoing, holders of Preferred Stock shall not have the right to vote for the election of any members of the Board of Directors of the Company.

Subscription Rights

Holders of Preferred Stock shall have the right to purchase equity securities that are issued by the Company in any future capital raising transaction that occurs after the Issue Date to the extent necessary in order to maintain their then-existing pro rata ownership percentage in the Company on a fully diluted, as-converted basis.

Transfers

Holders of Preferred Stock may not sell, transfer or otherwise dispose of any shares of Preferred Stock (including any transfer of all or a portion of the beneficial ownership of, or economic interest in, the Preferred Stock through derivative instruments or other similar arrangements) for a period of six months following the Issue Date, subject to customary exceptions (e.g. transfers to affiliate transfers, pledges, etc.) and with prior written notice to the Company; provided that, if the Preferred Stock is converted into Common Stock during such six-month period pursuant to “Conversion at the Option of the Company” above, the Conversion Shares issued upon such conversion shall not be subject to such transfer restriction. Thereafter, transfers may be permitted with prior written notice to the Company subject to compliance with all U.S. federal and other securities laws.

Board of Directors

For so long as the holders of Preferred Stock collectively beneficially own an aggregate of 5% or more of the aggregate number of shares of Common Stock outstanding on a fully diluted, as-converted basis, they collectively shall be entitled to designate one individual to serve as a non-voting observer of the Board of Directors of the Company (the “Board Observer”). The holders shall be responsible for all costs, expenses and risks related to the designation and service of the Board Observer.

Subscription Agreement	The purchase of shares of Preferred Stock (the “Investment”) shall be made pursuant to a Subscription Agreement which shall contain, among other things, representations and warranties of the Company and the Investor, and appropriate conditions to closing (including as outlined below).
Signing	The Investor and the Company will enter into the Subscription Agreement with respect to the Investment concurrently with the execution of the Merger Agreement by and among the Company, CPH, Merger Sub and a representative of the current owners of CPH (the “Merger Agreement”), with respect to the Company’s potential business combination with CPH pursuant to which a wholly owned subsidiary of the Company (“Merger Sub”) will merge with and into CPH with CPH being the surviving corporation (the “Business Combination”).
Closing	The closing of the Investment (“Closing”) will occur on the closing date of the Business Combination. The Company shall provide Investor at least five (5) days advance written notice of the proposed closing date (the “Closing Notice”). Within two (2) business days after receiving the Closing Notice, the Investor shall (a) deliver to the Company such information as is reasonably requested in the Closing Notice in order for the Company to issue shares of Preferred Stock to the Investor (or its designees) and (b) wire the purchase price for the Investment to an escrow account established at the Company’s transfer agent, as specified in the Closing Notice, to be released to the Company upon the closing of the Business Combination.
Closing Conditions	The Closing will be subject to the following conditions: (i) customary bring down of the representations and warranties of the Investor; (ii) all conditions precedent to the closing of the Business Combination set forth in the Merger Agreement, including the approval of the Company’s stockholders, shall have been satisfied or waived; (iii) the Business Combination shall have been, or substantially concurrently with the Investment, shall be, consummated in accordance with the terms of the Merger Agreement; and (iv) no governmental authority shall have enacted, issued, promulgated, enforced or entered any judgment, order, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of making consummation of the Investment illegal or otherwise preventing or prohibiting consummation of the Investment.

Use Of Proceeds

Proceeds from the Investment will be used to fund the purchase price under the Merger Agreement and for general working capital purposes as determined by the Company in its sole discretion.

Registration Rights

The Company will be obligated to file a resale “shelf” registration statement on Form S-3 (or, if Form S-3 is not available for use by the Company, another applicable registration form) (the “Registration Statement”) within 90 days of the Closing (the “Filing Deadline”) covering the shares of Common Stock issuable upon conversion of the Preferred Stock. The Company will use commercially reasonable efforts to have the Registration Statement declared effective by the SEC within 60 days of the Filing Deadline (the “Effectiveness Deadline”); provided that the Effectiveness Deadline will be extended to 120 days after the Filing Deadline if the Registration Statement is reviewed by, and the Company receives comments from, the SEC. The Company will use its commercially reasonable efforts to maintain the continuous effectiveness of the Registration Statement until all Conversion Shares cease to be registrable securities or such shorter period upon which the holders have notified the Company that such Conversion Shares have actually been sold. In addition, the holders will be entitled to “piggyback” registration rights with respect to the Conversion Shares on all registration statements of the Company that are filed on Form S-1, Form S-3 or similar forms with respect to any underwritten secondary offering of Common Stock as well as the ability to participate in such underwritten offering, subject to the right of the Company and the underwriters in their discretion to reduce the number of shares proposed to be registered by the holders on a pro rata basis. Notwithstanding the foregoing, the holders shall not have any rights to participate in the registration statement that Peninsula Pacific is entitled to cause the Company to file with respect to the shares of Common Stock to be issued to Peninsula Pacific in connection with the transactions contemplated by the Merger Agreement.

Termination Date

The Subscription Agreement will terminate upon the earlier to occur of: (i) such date and time as the Merger Agreement is terminated in accordance with its terms; (ii) upon the mutual written agreement of the Company and the Investor; or (iii) if any of the closing conditions in the Subscription Agreement are not satisfied prior to Closing and, as a result thereof, the Investment is not consummated. The Company will notify the Investor of the termination of the Merger Agreement promptly after its termination.
