(iii)

third, the balance of the distribution amount will be distributed to the Members, including the Manager, as their ownership interests appear.

The transferee or donee shall be merely an Economic Interest Owner. No transfer of a Member's interest in the Company (including any transfer of the Economic Interest or any other transfer which has not been approved by written consent of the Members holding at least 65% of all Company Interests) shall be effective unless and until written notice (including the name and address of the proposed transferee or donee and the date of such transfer) has been provided to the Company and the non-transferring Members.

ADDITIONAL MEMBERS

Section 11.1 - Additional Members Except for additional members related to the Subsequent Offering, as described in the Private Placement Memorandum, from the date of the formation of the Company, any person or entity acceptable to Members holding at least 65% of all Company Interests by their written consents may become a Member in the Company either by the issuance by the Company of Membership Interests for such consideration as the Members holding at least 65% of all Company Interests by their written consents shall determine, or as a transferee of a Member's Membership Interest or any portion thereof, subject to the terms and conditions of this Operating Agreement. No new Members shall be entitled to any retroactive allocation of losses, income or expense deductions incurred by the Company. The Manager may, at their option, at the time a Member is admitted, close the Company books (as though the Company's tax year had ended) or make pro-rata allocations of loss, income and expense deductions to a new Member for that portion of the Company's tax year in which a Member was admitted in accordance with the provisions of Section 706(d) of the Code and the Treasury Regulations promulgated thereunder.

DISSOLUTION AND TERMINATION

Section 12.1 Dissolution –

(I) at the time specified in its Articles of Organization;

(ii) written consent of Members holding at least 65% of all Company Interests; or

(iii) an Event of Dissociation of a Member, unless there are at least two remaining Members and the business of the Company is continued by the written consent of remaining Members holding a Majority Interest within 90 days after the Event of Dissociation, and

(iv) entry of a decree of final dissolution under Section 43 of the Connecticut Act.

Each of the Members hereby agrees that within the 60 days after the occurrence of an Event of Dissociation, they will promptly consent, in writing, to continue the business of the Company. Each of the Members further agrees promptly to consent, in writing, to continue the business of the Company upon a sale or gift either of a Member's entire Economic Interest to which all of the remaining Members do not consent within 45 days after the occurrence of such a sale or gift or upon a sale or gift of a Transferring Member's entire Membership Interest. Such consents shall be mailed or hand delivered to the principal place of business of the Company set forth in Section 2.3 hereof (or to such other address designated by the Managers) no later than 50 days after each Withdrawal Event or transfer by Member of its entire Economic Interest or Membership Interest). The sole remedy for breach of a Member's obligation to consent to continue the business of the Company under this Section shall be money damages (and not specific performance).

(b) Notwithstanding anything to the contrary in this Operating Agreement, if a Member or Members owning Company Interests which in the aggregate constitute not less than 65% of all Company Interests vote or consent in writing to dissolve the Company, then all of the Members shall agree in writing to dissolve the Company as soon as possible (but in any event not more than 10 days) thereafter.

(c) As soon as possible following the occurrence of any of the events specified in this Section 12.1 affecting the dissolution of the Company, the Managers shall proceed to wind up the Company's business in accordance with the Section 45 of the Connecticut Act.

(d) Except as expressly permitted in this Operating Agreement, a Member shall not voluntarily resign or take any other voluntary action, which directly causes an Event of Dissociation. Unless otherwise approved in writing by Members owning at least 65% of all Company Interests. A Member who resigns (a "Resigning Member") or whose Membership Interest is otherwise terminated by virtue of an Event of Dissociation, regardless of whether such Event of Dissociation was the result of a voluntary act by such Member, shall not be entitled to receive any distributions to which such Member would not have been entitled had such Member remained a Member. A Resigning Member shall become an Economic Interest Owner, except as otherwise expressly provided herein. Damages for breach of this Section 12.1(e) shall be monetary damages only (and not specific performance). Further, such damages may be offset against distributions by the Company to which the Resigning Member would otherwise be entitled.

SECTION 12.2 Winding Up - Upon the dissolution of the Company, the Manager may, in the name of and for and on behalf of the Company, prosecute and defend suits, whether civil, criminal or administrative, sell and close the Company’s business, dispose of and convey and distribute to the Members any remaining assets of the Company, all without affecting the liability of Members. Upon winding up of the Company, the assets shall be distributed as follows:

(a) To creditors, including Members and the Manager who are creditors, to the extent permitted by law, in satisfaction of liabilities of the Company, whether by payment or by making of reasonable provision for payment thereof, other than liabilities for which reasonable provision for payment has been made and liabilities to Members and former Members for distributions under (Sections 18-601 or 18-604 of the Act);

(b) To Members and former Members in satisfaction of liabilities for distributions under (Sections 18-601 or 18-604 of the Act); and

SECTION 12.3 Deficit Capital Accounts - Upon a liquidation of the Company within the meaning of Section 1.704-l (b)(2)(ii)(g) of the Treasury Regulations, if any Member has a deficit Capital Account (after giving effect to all contributions, distributions, allocations and other adjustments for all Fiscal Years, including the Fiscal Year in which such liquidation occurs), the Member shall have no obligation to make any Capital Contribution, and the negative balance of any Capital Account shall not be considered a debt owed by the Member to the Company or to any other Person for any purpose.

SECTION 12.4 Non-recourse to Other Members - Except as provided by applicable law or as expressly provided in this Agreement, upon dissolution, each Member shall receive a return of its Capital Contribution solely from the assets of the Company. If the assets of the Company remaining after the payment or discharge of the debts and liabilities of the Company are insufficient to return any Capital Contribution of any Member, such Member shall have no recourse against any other Member.

SECTION 12.5 Termination - Upon completion of the dissolution, winding up, liquidation and distribution of the assets of the Company, the Company shall be deemed terminated.

Amendment #1, dated, March 12, 2007

2nd Round Investment Offering – (includes 5th investor letter)

Silica is seeking up to $2 million in capital and is offering a 5% equity interest per million, or any part thereof, to accredited investors, only, (the “Round Two Investors”). The minimum investment is $25,000 for those investors that invested in Round One and $50,000 for new investors.

Round Two Investors shall be valuation - protected should Silica engage in subsequent equity offerings, up to $2 million, at a purchase price lower than the purchase price paid by the Round Two Investors. The price adjustment, determined on a weighted average, will be based on a valuation of the Company (as adjusted for stock splits and recapitalizations) prior to inclusion of such subsequent capital contributions.

Distributions to Round Two Investors shall have a priority to distributions to Silica Tech Holdings, LLC, the Manager of Silica, but shall follow distributions to the Round One Investors, pursuant to the Operating Agreement. Such priority distributions to Round Two Investors shall equal 115% of their Round Two Investment.

Under Silica’s present plan, the funds invested from the Round Two Investors will be used primarily to further commercialize its intellectual property, including the making of silicon samples, the building of the first production machines for making silicon and/or crystalline silicon ingots from silicon tetrachloride, and for funding, to the extent reasonable, overhead expenses associated with the commercialization. Some of this work may be sub-contracted to, or a strategic alliance(s) formed with, third parties. In addition, when, as, and if the Jetion $5 million is received and depending on the Round Two investment amount, such total funds may be used for payables, provided, however, that the amount used for payables may not exceed (i) 15% of the Round Two Investment up to $250,000 or (ii) up to a total of $500,000 if the Jetion $5 million is also received.

(Note: As Silica continues to commercialize its technology, additional funds will be needed, from time to time, for equipment, new patent filings, and other technology improvements. To the extent possible, Silica will continue to raise such funds via the Jetion approach that is, receiving advances against sales orders, which approach does not result in equity dilution. Moreover, the Manager believes that once Silica has produced competitive quality samples and started shipping product, bank loans and other fund raising avenues will surface.)

Investments from Round Two Investors are expected on or about March 15th, but not later than March 30; however, Silica reserves the right to extend the offering period.

Round Two Investors shall receive a Subscription Agreement and related disclosure documents, including, but not limited to a Confidential Investor Summary, a Power Point Presentation, financial material, and other material in addition to the Recent Events attachment.

Round Two Investors will acknowledge that they have read all material requested and/or provided and that they have been permitted the opportunity to evaluate and ask questions about the material received.

Part of Amendment #1

Recent Events (Post the 4th Investor Letter, dated October 31, 2006)

Silica and Jetion Holdings Limited (‘Jetion’), a Chinese manufacturer that currently produces solar cells and modules and that plans an estimated $80 million IPO on the London AIM (the “Alternate Investment Market”), and Silica have agreed in principal to the forming of a joint venture in China and the advancing of $5 million to Silica, pursuant to the attached term sheet. A Joint Venture Agreement is currently being finalized for an anticipated closing on or about the end of March.

Silica’s patent counsel, Patton Boggs, just recently filed a full utility and a PCT (Patent Cooperation Treaty) filing on the silicon/polycrystalline patent application and is preparing to file by April 6th a full utility and PCT filing on the thin-film application. The filings will cover, at least, United States, Western Europe, China, Malaysia, Thailand, India, Russia, and Taiwan.

There have been no material changes with respect to the on-going Silica vs. J-Fiber litigation and outside of reaching a settlement, which Silica is open to, there are no material expected to occur until year end or the beginning of 2008 when discovery proceedings should continue. However, Silica understands that recently J-Fiber has been sending indemnification letters to its fiber customers, agreeing to indemnify them in the event of a patent infringement claim by Silica.

Amendment #2, dated, April 24, 2008

Round 2 (B) Investment Offering

Silica is seeking up to $1.5 million in capital and is offering a 4.55% equity interest per million, or any part thereof, to accredited investors, only, (the “Round Two (B) Investors”). The minimum investment is $25,000 for those investors that invested in Round One and $50,000 for new investors.

Round Two (B) Investors shall be valuation - protected should Silica engage in subsequent equity offerings, up to $3 million, at a purchase price lower than the purchase price paid by the Round Two (B) Investors. The price adjustment, determined on a weighted average, will be based on a valuation of the Company (as adjusted for stock splits and recapitalizations) prior to inclusion of such subsequent capital contributions.

Distributions to Round Two (B) Investors shall have a priority to distributions to Silica Tech Holdings, LLC, the Manager of Silica, but shall be after distributions made to the Round One and Round 2 (A) Investors, pursuant to the Operating Agreement.

Under Silica’s present plan, approximately $600 thousand of the funds invested from the Round Two (B) Investors will be used primarily for developing a one or two step process for the making of ingots; the balance of the funds will be used for working capital.

(Note: As Silica continues to commercialize its technology, additional funds will be needed, from time to time, for equipment, new patent filings, other technology improvements and working capital. It is expected that these achievements will increase the value of Silica such that new investors will pay a higher price. To the extent possible Silica will intends to raise funds by way of receiving advances against sales orders, which approach does not result in equity dilution. Moreover, the Manager believes that once Silica has produced competitive quality samples and started shipping product, bank loans and other fund raising avenues will surface.)

Investments from Round Two (B) Investors are expected by May 1, 2008; however, Silica reserves the right to extend the offering period and/or to increase the offering price.

Silica plans to be publicly traded by year-end, which will result in the conversion of Silica from a limited liability to a corporation. Accordingly, in exchange for providing market liquidity to Round Two (B) Investors, Points 2 and 3 will be reduced and/or eliminated.

Round Two Investors shall receive a Subscription Agreement and related disclosure documents, including, but not limited to a Confidential Investor Memorandum, a Power Point Presentation, financial material, investor letters, and other material.

Round Two (B) Investors will acknowledge that they have read all material requested and/or provided and that they have been permitted the opportunity to evaluate and ask questions about the material received.
