In May 2010, the Company acquired, through its wholly-owned Netherlands subsidiary, CW-Cooperatief, a 50% interest in NSC, a development stage Mexican company. The Company has since purchased, through the conversion of a loan it made to NSC, sufficient shares to raise its ownership interest in NSC to 99.99%. NSC was formed to pursue a project (the “Project”) that originally encompassed the construction, operation and minority ownership of a 100 million gallon per day seawater reverse osmosis desalination plant to be located in northern Baja California, Mexico and accompanying pipelines to deliver water to the Mexican potable water system. As discussed in paragraphs that follow, during 2015 the scope of the Project was defined by the State of Baja California (the “State”) to consist of a first phase consisting of a 50 million gallon per day plant and a pipeline that connects to the Mexican potable water infrastructure and a second phase consisting of an additional 50 million gallons of production capacity.

In November 2012, NSC entered into a lease with an effective term of 20-years from the date of full operation of the Project’s desalination plant, with the Comisión Federal de Electricidad for approximately 5,000 square meters of land on which it plans to construct the water intake and discharge works for the plant. The amounts due on this lease are payable in Mexican pesos at an amount that is currently equivalent to approximately $15,000 per month. This lease may be cancelled by NSC should NSC ultimately not proceed with the Project.

In August 2014, the State enacted new legislation to regulate Public-Private Association projects which involve the type of long-term contract between a public-sector authority and a private party that NSC is seeking to complete the Project. Pursuant to this new legislation, in January 2015, NSC submitted an expression of interest for its project to the Secretary of Infrastructure and Urban Development of the State of Baja California (“SIDUE”). SIDUE accepted NSC’s expression of interest and requested that NSC submit a detailed proposal for the Project that complies with the requirements of the new legislation. NSC submitted this detailed proposal (the “APP Proposal”) to SIDUE in late March 2015. The new legislation required that such proposal be evaluated by SIDUE and submitted to the Public-Private Association Projects State Committee (the “APP Committee”) for review and authorization. If the Project was authorized the State would be required to conduct a public tender for the Project.

In response to its APP Proposal, in September 2015 NSC received a letter dated June 30, 2015 from the Director General of the Comisión Estatal del Agua de Baja California (“CEA”), the State agency with responsibility for the Project, stating that (i) the Project is in the public interest with high social benefits and is consistent with the objectives of the State development plan; and (ii) that the Project should proceed, and the required public tender should be conducted. In November 2015, the State officially commenced the tender for the Project, the scope of which the State defined as a first phase to be operational in 2019 consisting of a 50 million gallon per day plant and a pipeline that connects to the Mexican potable water infrastructure and a second phase to be operational in 2024 consisting of an additional 50 million gallons per day of production capacity.

A consortium comprised of NSC, NuWater S.A.P.I. de C.V. (“NuWater”) and Degremont S.A. de C.V. (the “Consortium”) submitted its tender for the Project in

April 2016 and in June 2016, the State designated the Consortium as the winner of the tender process for the Project.

Due to the amount of capital the Project requires, NSC will ultimately need an equity partner or partners for the Project. Consequently, NSC’s tender to the State for the Project was based upon the following: (i) NSC will sell or otherwise transfer the land and other Project assets to a new company (“Newco”) that would build and own the Project; (ii) NSC’s potential partners would provide the majority of the equity for the Project and thereby would own the majority interest in Newco; (iii) NSC would maintain a minority ownership position in Newco; and (iv) Newco would enter into a long-term management and technical services contract for the Project with an entity partially owned by NSC or another Company subsidiary.

In August 2016, NSC and NuWater incorporated Newco under the name Aguas de Rosarito S.A.P.I. de C.V. (“AdR”), a special purpose company, to complete the Project and executed a shareholders agreement for AdR agreeing among other things that (i) AdR would purchase the land and other Project assets from NSC on the date that the Project begins commercial operations and (ii) AdR would enter into a Management and Technical Services Agreement with NSC effective on the first day that the Project begins commercial operations. As of December 31, 2017, NSC owned 99.6% of the equity of AdR.

On August 22, 2016, the Public Private Partnership Agreement for public private partnership number 002/2015, bid number SIDUE-CEA-APP-2015-002 (“APP Contract”), was executed between AdR, CEA, the Government of Baja California represented by the Secretary of Planning and Finance and the Public Utilities Commission of Tijuana (“CESPT”). The APP Contract requires AdR to design, construct, finance and operate a seawater desalination plant (and accompanying aqueducts) with a capacity of up to 100 million gallons per day in two phases: the first with a capacity of 50 million gallons per day and an aqueduct to the Mexican potable water system in Tijuana, Baja California; and the second phase with a capacity of 50 million gallons per day and an aqueduct to a second delivery point in Tijuana. The first phase must be operational within 36 months of commencing construction and the second phase must be operational by the end of 2024. The APP Contract further requires AdR to operate and maintain the plant and aqueducts for a period of 37 years starting from the commencement of operation of the first phase. At the end of the operating period, the plant and aqueducts will be transferred to CEA.

In December 2016, the Congress of the State of Baja California, Mexico passed Decreto #57 which, among other things, ratified and authorized the payment obligations of the corresponding public entities under the APP Contract. During 2017, following consultations between representatives of the State of Baja California and the Ministry of Finance of the Federal Government of Mexico, it was determined that certain amendments to Decreto #57 were required in order to comply with recent changes to the Federal Financial Discipline Law for Federative Entities and Municipalities. In addition, it was necessary to amend Decreto #57 to authorize the inclusion of revenues from the CESPT in the primary payment trust for the Project. These amendments were included in Decreto #168, which was approved by the Congress of the State of Baja California in December 2017. Following its issuance, two actions were filed in Mexican Courts against Decreto #168. While neither NSC nor AdR have been named as a party in these actions, based upon publicly available information, the Company believes (1) one of these actions consists of a challenge filed by certain members of the Congress of the State of Baja California alleging certain elements of Decreto #168 are contrary to the Mexican constitution; and (2) that the other action represents an amparo (i.e. a constitutional appeal) filed by certain members of indigenous groups that alleges Decreto #168 violates certain of the human rights and individual guarantees they are afforded under the Mexican constitution. With respect to the action mentioned in (1), the Company cannot presently determine what impact, if any, it will have upon the Project. With respect to the action mentioned in number (2), according to publicly available information, the Company understands that on March 27, 2018, a resolution dismissing such proceeding was issued (and subsequently published in the official lists of the corresponding court on April 16, 2018), as the claimants were not able to evidence their legal interest. On May 3, 2018, the court deciding on such action determined this resolution to be final, as the claimants did not file a remedy against it.

Both the exchange rate for the Mexico peso relative to the dollar and general macroeconomic conditions in Mexico have varied since the execution of the APP Contract. These changes have adversely impacted the estimated construction, operating, and financing costs for the Project. The APP Contract and the APP Law allow for the parties to negotiate (but do not guarantee) modifications to the water tariff in the event of such significant macroeconomic condition changes. On February 10, 2017, AdR submitted proposals to the CEA requesting an increase to the water tariff to compensate for changes in foreign exchange rates, lending rates and certain changes in law which have impacted the Project. On June 1, 2018, AdR and the CEA executed an amendment to the APP Contract which, among other things, increases the scope of Phase 1 of the Project by including the aqueduct originally designated for Phase 2, and addresses AdR’s concerns regarding the impact on the Project of changes in the exchange rate for the peso relative to the dollar and changes in interest rates that have occurred subsequent to the submission of the Consortium’s bid for the Project. As a result of this amendment to the APP Contract, the cost of Phase 1 of the Project and the related water tariff to be charged by AdR have not yet been finalized, as such amounts will be based upon the bid submitted by the Consortium, the changes set forth in the amendment to the APP contract and the economic conditions (e.g. interest rates and currency exchange rates) in effect on the financial closing date for Phase 1.

In February 2018, AdR executed a subscription agreement (the “Agreement”) for the equity funding required for the Project. The Agreement calls for NSC to retain a minimum of 25% of the equity in AdR. One or more affiliates of Greenfield SPV VII, S.A.P.I. de C.V. (“Greenfield”), a Mexico company managed by an affiliate of a leading U.S. asset manager, will acquire a minimum of 55% of the equity of AdR. The Agreement also provides Suez Medio Ambiente México, S.A. de C.V. (“Suez”), a subsidiary of SUEZ International, S.A.S., with the option to purchase 20% of the equity of AdR. If Suez does not exercise this option, NSC will retain 35% of the equity of AdR and Greenfield will acquire 65% of the equity of AdR. The Agreement will become effective when the additional conditions related to the Project are met, including but not limited to those conditions discussed previously. The aggregate investment to be made by the equity partners in the Project, in the form of equity and subordinated shareholder loans, is presently estimated at approximately 20% of the total cost of Phase 1 of the Project.

If AdR is ultimately unable to proceed with the Project, the land NSC has purchased and the right of way deposits may lose their strategic importance derived from their association with the Project and consequently may decline in value. If AdR does not proceed with the Project, NSC may ultimately be unable to sell this land or recoup their right of way deposits for amounts at least equal to their carrying values as of June 30, 2018 of

approximately $20.6 million and $1.3 million, respectively. Any loss on the sale of the land, or impairment losses NSC may be required to record as a result of a decrease in the (i) fair value of the land; or (ii) value of the rights of way arising from the inability to complete the Project could have a material adverse impact on the Company’s results of operations.

Included in the Company’s results of operations are general and administrative expenses from NSC and AdR, consisting of organizational, legal, accounting, engineering, consulting and other costs relating to Project development activities. Such expenses amounted to approximately $664,000 and $885,000 for the three months ended June 30, 2018 and 2017, respectively, and $1,312,000 and $1,605,000 for the six months ended June 30, 2018 and 2017, respectively. The assets and liabilities of NSC and AdR included in the Company’s consolidated balance sheets amounted to approximately $24.4 million and $208,000, respectively, as of June 30, 2018 and approximately $22.3 million and $173,000 respectively, as of December 31, 2017.

Immediately following CW-Cooperatief’s acquisition of its initial 50% ownership in NSC, the remaining 50% ownership interest in NSC was held by an unrelated company, Norte Sur Agua, S. de R.L. de C.V. (“NSA”). NSA subsequently transferred ownership of half of its shares in NSC to EWG Water LLC (“EWG”) and the other half of its shares in NSC to Alejandro de la Vega (the “individual shareholder”). In February 2012, the Company paid $300,000 to enter into an agreement (the “Option Agreement”) that provided it with an option, exercisable through February 7, 2014, to purchase the shares of NSC owned by the individual shareholder for a price of $1.0 million along with an immediate power of attorney to vote those shares. Such shares constituted 25% of the ownership of NSC as of February 2012. In May 2013, NSC repaid a $5.7 million loan payable to CW-Cooperatief by issuing additional shares of its stock. As a result of this share issuance to CW-Cooperatief, the Company acquired 99.99% of the ownership of NSC. The Option Agreement contained an anti-dilution provision that required the Company to issue new shares in NSC of an amount sufficient to maintain the individual shareholder’s 25% ownership interest in NSC if (i) any new shares of NSC were issued subsequent to the execution of the Option Agreement; and (ii) the Company did not exercise its share purchase option by February 7, 2014. The Company exercised its option and paid the $1.0 million to the individual shareholder to purchase the Option Agreement shares in February 2014.

In October 2015, the Company learned that EWG filed a lawsuit against the individual shareholder, NSC, NSA, CW-Cooperatief, other third parties, and the Public Registry of Commerce of Tijuana, Baja California in the Civil Court located in Tecate, Baja California, Mexico. In this lawsuit, EWG challenged, among other things, the capital investment transactions that increased the Company’s ownership interest in NSC to 99.99%. EWG requested that the court, as a preliminary matter: (a) suspend the effectiveness of the challenged transactions; (b) order public officials in Mexico to record the pendency of the lawsuit in the public records; and (c) appoint an inspector for NSA and NSC to oversee its commercial activities. The court granted, ex-parte, the preliminary relief sought by EWG, which resulted in the placement of inscriptions for the lawsuit on NSC’s public records.

On April 5, 2016, NSC filed a motion for reconsideration with the Tecate, Mexico court asking, among other things, that the court; (i) reverse its order to record the pendency of the lawsuit in the public records; (ii) cancel the appointment of the inspector; and (iii) allow NSC to provide a counter-guarantee to suspend the effects of the court’s order regarding the challenged transactions. On April 26, 2016, the Tecate, Mexico court issued an interlocutory judgment (i) ordering the cancellation of the inscriptions on NSC’s public records; and (ii) rejecting NSC’s motion for cancellation of the appointment of the inspector.

On May 17, 2016, NSC filed a claim with the Third District Court in Matters of Amparo and Federal Trials in the City of Tijuana, Baja California (the “Amparo Court”) challenging the Tecate, Mexico court ex-parte order which appointed an inspector over NSC’s commercial activities. On July 29, 2016, the Amparo Court found that such appointment is unconstitutional and reversed the Tecate, Mexico court’s appointment of an inspector.

Neither NSC nor CW-Cooperatief have been officially served with such claim, nor has AdR been notified that it has to appear for such trial. However, the Company understands that this claim is similar to the Tecate Claim in the petitions sought by EWG. In this claim, EWG challenged, among other things, the transactions contemplated under the Option Agreement, and therefore, the capital investment transactions that increased the ownership interest of CW-Cooperatief in NSC to 99.99%,

as a consequence of the Option Agreement. EWG requested that the court, as a preliminary matter, to: (a) suspend the effectiveness of the challenged transactions; (b) order public officials in Mexico to record the pendency of the lawsuit in the public records (including a special request to register a lien over the real estate owned by NSC); (c) appoint an inspector for NSC to oversee its commercial activities; and (d) order public officials in Mexico and credit institutions abroad to refrain from authorizing or executing any legal act related with the activities of the plaintiff, the co-defendants and the third party called to trial to avoid damages to third parties, including those with whom negotiations or any form of commercial or administrative activities, or activities of any other nature related with the “Rosarito” water desalination project, are being conducted. The Company understands that the Tenth Civil Judge granted, ex-parte, the preliminary relief sought by EWG, which resulted in the issuance of official writs to several governmental/public entities involved with the Project. AdR and NSC are in the process of preparing legal responses to this claim under the belief they will be officially served in the near

future.

In April 2018, AdR filed an amparo (i.e. a constitutional appeal) against the official writs issued by the Tenth Civil Judge to two governmental entities. In May 2018, the amparo claim was amended to also request protection against additional official writs issued by the Tenth Civil Judge to two other governmental entities and one banking institution. In May 2018, the Third District Court for Amparo and Federal Trials in the State of Baja California with residence in Tijuana granted a temporary suspension of the effects and consequences of the claimed official writs issued by the Tenth Civil Judge pending a further determination by the Third District Court.
