AGREEMENT AND PLAN OF CONTRIBUTION

Exhibit 10.1

THIS AGREEMENT AND PLAN OF CONTRIBUTION (this “Agreement”) is made and entered into as of the 17th day of January, 2012, by and between Castwell Precast Corporation, a Nevada corporation (“Castwell”), Summer Energy, LLC, a Texas limited liability company (“Summer”), and all of the members of Summer whose names appear on the signature pages to this Agreement (each, a “Summer Member”, and collectively, the “Summer Members”); based on the following:

RECITALS

The parties desire to enter into this Agreement to set forth the terms and conditions of the corporate reorganization pursuant to which the Summer Members will contribute all of their units of membership interest in Summer to Castwell in exchange for shares of Castwell common stock (the “Contribution”). Upon the closing of the Contribution, Summer will become a wholly-owned subsidiary of Castwell. The Contribution by the Summer Members is being conducted for the purposes of effecting a tax-free contribution pursuant to Section 351 of the Internal Revenue Code of 1986, as amended (the “Code”).

AGREEMENT

Based on the stated premises, which are incorporated herein by reference, and for and in consideration of the mutual covenants and agreements hereinafter set forth, the mutual benefits to the parties to be derived herefrom, and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

ARTICLE I

THE CONTRIBUTION

1.01

The Contribution.

Upon the terms and subject to the satisfaction or waiver of the conditions set forth in this Agreement, on the Effective Date (as defined in Section 1.02 herein) the Summer Members shall contribute their units of membership interest, which shall constitute all of the issued and outstanding units of membership interest in Summer (each unit of membership interest being referred to as a “Summer Interest”, and collectively as the “Summer Interests”), to Castwell in exchange for shares of Castwell’s common stock as set forth in Article II below.

1.02

Effective Date of Contribution. Upon the terms and subject to the conditions hereof, as soon as practicable after the satisfaction or waiver of the conditions set forth in Articles VI and VII of this Agreement, the Contribution shall be effectuated by each Summer Member delivering to Castwell an Assignment of Membership Units substantially in the form attached hereto as Exhibit A (each, an “Assignment”, and collectively, the “Assignments”). The date for the Closing of the Contribution shall be referred to herein as the “Effective Date”.

ARTICLE II

EXCHANGE OF CASTWELL SHARES

2.01

Exchange of Castwell Shares. On the Effective Date, and after giving effect to the reverse stock split and Castwell charter amendments described in Section 5.01, each Summer Interest issued and outstanding immediately prior to the Effective Date and all rights in respect thereof shall be exchanged into the right to receive one post-split share of common stock of Castwell, par value $0.001 (the “Castwell Shares”), so that the 9,697,624 Summer Interests that are issued and outstanding immediately before the Contribution are converted into the right to receive 9,697,624 post-split Castwell Shares. No fractional Castwell Shares or interests shall be issued in connection with the foregoing exchange. If any holder of Summer Interests would otherwise be entitled to a fractional share upon exchange thereof, Castwell shall round up the number of Castwell Shares to be issued to such holder to the nearest whole share. On the Closing, each holder of Summer Interests shall, upon the delivery of the Assignment representing such Summer Interests to the registrar and transfer agent of Castwell, together with the investment representation letter and all other documents and materials reasonably required by such transfer agent to be delivered in connection therewith, be entitled to receive a certificate or certificates evidencing the Castwell Shares as provided herein.

2.02

Conversion of Summer Warrants; Credit Facility Agreements. The issued and outstanding seven-year warrants to purchase a total of 400,000 Summer Interests at an exercise price per unit of membership interest of $0.60 per share (the “Summer Warrants”) shall upon the Closing, and without further action, be assumed by Castwell and modified so that, in lieu of having the right to acquire such Summer Interests on exercise, the holders thereof shall have the right to acquire 400,000 Castwell Shares at an exercise price of $0.60 per share and all other terms of the Summer Warrants shall remain unchanged. The contingent obligations of Summer pursuant to those certain Agreements to Assist with Credit Facility, each dated on or about November 30, 2011, (collectively, the “Credit Facility Agreements”) shall upon the Closing, and without further action, be assumed by Castwell and modified so that, in lieu of having the right to acquire such Summer Interests on exercise, the holders thereof shall have the right to acquire 1,515,152 Castwell Shares, and the other terms of the Credit Facility Agreements shall remain unchanged.

2.03

Adjustments to Exchange Ratio. The number of Castwell Shares to be issued and delivered pursuant to this Agreement and the number of Castwell Shares to be issued upon exercise of the Summer Warrants shall be appropriately adjusted to take into account any stock split, stock dividend, reverse stock split (except for the proposed reverse split set forth in Section 5.01), recapitalization, or similar change in the Castwell common stock which may occur (with the prior written consent of Summer) between the date of the execution of this Agreement and the date of delivery of such shares to provide the holders of Summer Interests and Summer Warrants with the same economic effect as contemplated by this Agreement prior to such event.

2.04

Reservation of Shares for Summer Warrants; Reservation for Summer Interests under Credit Facility Agreements. Castwell shall retain and reserve that number of authorized and unissued shares of Castwell common stock that shall be issuable upon the exercise of the Summer Warrants or issuable upon an election under the Credit Facility Agreements at any given time until their respective exercise, conversion, or termination as applicable.

2.05

Restricted Stock; One-Year Restriction Period. The Castwell Shares to be issued pursuant to the transactions contemplated by this Agreement will not be registered and shall be characterized as “restricted securities” under the federal securities laws, and under such laws such shares may be resold without registration under the Securities Act only in certain limited circumstances. Each certificate evidencing Castwell Shares to be issued pursuant to the transactions contemplated by this Agreement shall bear a legend in substantially the following form:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. SUCH SECURITIES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR THE AVAILABILITY OF AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS.

The Summer Members acknowledge and agree that, as “restricted securities,” the Castwell Shares to be received by them may not be transferred, hypothecated, sold or otherwise disposed of until (i) a registration statement with respect to such securities is declared effective under the Securities Act, or (ii) Castwell receives an opinion of counsel for the holders of such Castwell Shares, reasonably satisfactory to counsel for Castwell that an exemption from the registration requirements of the Securities Act is available. However, notwithstanding the immediately preceding sentence, until: Castwell has become subject to the reporting requirements of section 13 or 15(d) of the Exchange Act; has filed all reports and other materials required to be filed by section 13 or 15(d) of the Exchange Act, as applicable, during the preceding 12 months (or for such shorter period that Castwell was required to file such reports and materials), other than Form 8-K reports; and a period of at least one (1) year has elapsed from the date on which current “Form 10” information has been filed by Castwell (the “Restriction Period”) reflecting its acquisition of Summer as provided herein, no Summer Member shall sell in any public market any Castwell Shares, or any interest therein, received pursuant to this Agreement.

2.06

Closing. The closing of the transactions contemplated hereby (the “Closing”) shall be held at a mutually agreed upon time and place on such date as may be agreed to in writing by the parties (the “Closing Date”). The Closing Date shall occur not more than five days following the last to be satisfied of the conditions precedent to the parties’ obligation to closing set forth in Articles VI and VII hereof. The Closing may be accomplished by express mail, overnight courier, conference telephone call or as otherwise agreed to by the respective parties or their duly authorized representatives.

There shall be any actual or threatened action or proceeding before any court or any governmental body which shall seek to restrain, prohibit, or invalidate the transactions contemplated by this Agreement and which, in the reasonable judgment of such board of directors, made in good faith and based upon the advice of its legal counsel, makes it inadvisable to proceed with the transactions contemplated by this Agreement; or

For purposes of the representations and warranties of Castwell contained in this Article III, disclosure in any section of the Castwell Disclosure Schedules of any facts or circumstances shall be deemed to be an adequate response and disclosure of such facts or circumstances with respect to all representations or warranties by Castwell calling for disclosure of such information, whether or not such disclosure is specifically associated with or purports to respond to one or more or all of such representations or warranties, if it is reasonably apparent on the face of the Disclosure Schedules that such disclosure is applicable. The inclusion of any information in any section of the Castwell Disclosure Schedules by Castwell shall not be deemed to be an admission or evidence of materiality of such item, nor shall it establish a standard of materiality for any purpose whatsoever.

3.01

Organization. Castwell is a corporation duly organized, validly existing, and in good standing under the laws of the State of Nevada and its wholly-owned subsidiary, Castwell Precast, Inc., is a corporation duly organized, validly existing and in good standing under the laws of the State of Utah.

The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated by this Agreement in accordance with the terms hereof will not, violate any provision of the articles of incorporation or bylaws of any of the Castwell Entities or other agreement to which any Castwell Entity is a party or by which it is bound.

The execution, delivery and performance by Castwell of this Agreement have been duly and validly approved and authorized by the board of directors of Castwell, and, other than approval by its stockholders, no other actions or proceedings on the part of Castwell are necessary to authorize this Agreement and the transactions contemplated hereby and thereby. This Agreement constitutes the legal, valid and binding obligation of Castwell, enforceable in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent transfer, moratorium, reorganization or other laws from time to time in effect which affect creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

There are no outstanding agreements or waivers extending the statutory period of limitation applicable to any tax return of Castwell.

▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇
▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇

Re:

Acquisition of Shares of Common Stock of Castwell Precast Corporation

Ladies and Gentlemen:

The undersigned understands that Castwell Precast Corporation, a Nevada corporation (the “Company”), has or will acquire all issued and outstanding membership interests of Summer Energy LLC, a Texas limited liability company (“Summer”), in exchange for shares of the Company’s common stock pursuant to the terms and conditions of an Agreement and Plan of Contribution, dated as of January 17, 2012, by and among the Company, Summer and the members of Summer (the “Contribution Agreement”). The undersigned is a member of Summer and is entitled to receive the number of shares of the Company’s common stock set forth above pursuant to the terms of the Contribution Agreement.

In connection with the acquisition by the undersigned of the above shares of the Company’s common stock (the “Securities”), and in order to permit the Company to document its compliance with applicable corporate and securities laws, the undersigned represents that the Securities are being acquired without a view to, or for resale in connection with, any distribution of such Securities or any interest therein without registration or other compliance under the Securities Act of 1933, as amended (the “Securities Act”), and that the undersigned has no direct or indirect participation in any such undertaking or in the underwriting of such an undertaking.

The undersigned understands that the Securities have not been registered, but are being acquired by reason of a specific exemption under the Securities Act as well as under certain state statutes for transactions by an issuer not involving any public offering and that any disposition of the subject Securities may, under certain circumstances, be inconsistent with this exemption and may make the undersigned an “underwriter” within the meaning of the Securities Act.

The undersigned acknowledges that the Securities must be held and may not be sold, transferred, or otherwise disposed of for value unless they are subsequently registered under the Securities Act or an exemption from such registration requirements is available; the Company is under no obligation to register the Securities under the Securities Act except as may be expressly agreed to by it in writing; the Company’s registrar and transfer agent will maintain a stop transfer order against the registration of transfer of the Securities; and the certificates representing the Securities will bear legends in substantially the following form so restricting the sale of such Securities.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ARE “RESTRICTED SECURITIES” WITHIN THE MEANING OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT. THESE SECURITIES MAY NOT BE RESOLD OR TRANSFERRED WITHOUT REGISTRATION UNDER THE SECURITIES ACT OR THE AVAILABILITY OF AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS.

The Company may refuse to register transfer of the Securities in the absence of compliance with rule 144 promulgated under the Securities Act unless the undersigned furnishes the Company with a “no action” or interpretative letter from the Securities and Exchange Commission or an opinion of counsel reasonably acceptable to the Company stating that the transfer is proper; further, unless such letter or opinion states that the Securities are free of any restrictions under the Securities Act, the Company may refuse to transfer the Securities to any transferee who does not furnish in writing to the Company the same representations and agree to the same conditions with respect to such Securities as set forth herein. The Company may also refuse to transfer the Securities if any circumstances are present reasonably indicating that the transferee’s representations are not accurate.

The undersigned also represents that the undersigned is an accredited investor as defined in Rule 501 of Regulation D promulgated under the Securities Act because he, she or it meets one or more of the following conditions (please check appropriate items):

_____

1. The undersigned is a natural person whose individual net worth, or joint net worth with that person’s spouse, at the time of purchase exceeds $1,000,000 excluding the value of the primary residence of such natural person;

_____

2. The undersigned is a natural person who had an income in excess of $200,000 in each of the two most recent years or joint income with that person’s spouse in excess of $300,000 in each of those years and has a reasonable expectation of reaching the same income level in the current year;

_____

3. The undersigned is a trust with total assets in excess of $5,000,000, not formed for the specific purpose of acquiring the securities offered, whose purchase is directed by a sophisticated person as described in Rule 506(b)(2)(ii) under the Securities Act;

_____

4. The undersigned is a private business development company as defined in Section 202(a)(22) of the Investment Advisors Act of 1940;
