Platinum

In July 2012, we entered into an agreement with Platinum to provide us with a credit facility of up to $50 million.  Following the approval of Lymphoseek, Platinum was committed under the terms of the agreement to extend up to $35 million in debt financing to the Company.  During the three-month period ended March 31, 2016, $306,000 of interest was compounded and added to the balance of the Platinum Note.  As of March 31, 2016, the outstanding principal balance of the Platinum Note was approximately $8.8 million, with $27.3 million currently available under the credit facility.  An additional $15 million is potentially available under the credit facility on terms to be negotiated.

The Platinum Note is reflected on the consolidated balance sheets at its estimated fair value, which includes the estimated fair value of the embedded conversion option of $1.9 million.  Changes in the estimated fair value of the Platinum Note were decreases of $1.1 million and $1.7 million, respectively, and were recorded as non-cash changes in fair value of the conversion option during the three-month periods ended March 31, 2016 and 2015.  The estimated fair value of the Platinum Note was $10.7 million as of March 31, 2016.

Capital Royalty Partners II, L.P.

In May 2015, Navidea and its subsidiary Macrophage Therapeutics, Inc., as guarantor, executed a Term Loan Agreement (the CRG Loan Agreement) with Capital Royalty Partners II L.P. (CRG) in its capacity as a lender and as control agent for other affiliated lenders party to the CRG Loan Agreement (collectively, the Lenders) in which the Lenders agreed to make a term loan to the Company in the aggregate principal amount of $50 million (the CRG Term Loan), with an additional $10 million in loans to be made available upon the satisfaction of certain conditions stated in the CRG Loan Agreement.  During the three-month period ended March 31, 2016, $519,000 of interest was compounded and added to the balance of the CRG Term Loan.  As of March 31, 2016, the outstanding principal balance of the CRG Term Loan was $51.8 million.

In connection with the CRG Loan Agreement, the Company recorded a debt discount related to lender fees and other costs directly attributable to the CRG Loan Agreement totaling $2.2 million, including a $1.0 million facility fee which is payable at the end of the term or when the loan is repaid in full.  A long-term liability has been recorded for the $1.0 million facility fee.  The debt discount is being amortized as non-cash interest expense using the effective interest method over the term of the CRG Loan Agreement.  As of March 31, 2016, the balance of the debt discount was $2.0 million.

The CRG Term Loan is collateralized by a security interest in substantially all of the Company's assets.  In addition, the CRG Loan Agreement requires that the Company adhere to certain affirmative and negative covenants, including financial reporting requirements and a prohibition against the incurrence of indebtedness, or creation of additional liens, other than as specifically permitted by the terms of the CRG Loan Agreement.  The Lenders may accelerate the payment terms of the CRG Loan Agreement upon the occurrence of certain events of default set forth therein, which include the failure of the Company to make timely payments of amounts due under the CRG Loan Agreement, the failure of the Company to adhere to the covenants set forth in the CRG Loan Agreement, and the insolvency of the Company.  The covenants of the CRG Loan Agreement include a covenant that the Company shall have EBITDA of no less than $5 million in each calendar year during the term or revenues from sales of Lymphoseek in each calendar year during the term of at least $22.5 million in 2016, with the target minimum revenue increasing in each year thereafter until reaching $45 million in 2020.  However, if the Company were to fail to meet the applicable minimum EBITDA or revenue target in any calendar year, the CRG Loan Agreement provides the Company a cure right if it raises 2.5 times the EBITDA or revenue shortfall in equity or subordinated debt and deposits such funds in a separate blocked account.  Additionally, the Company must maintain liquidity, defined as the balance of unencumbered cash and permitted cash equivalent investments, of at least $5 million during the term of the CRG Term Loan.  The events of default under the CRG Loan Agreement also include a failure of Platinum to perform its funding obligations under the Platinum Loan Agreement at any time as to which the Company had negative EBITDA for the most recent fiscal quarter, as a result either of Platinum’s repudiation of its obligations under the Platinum Loan Agreement, or the occurrence of an insolvency event with respect to Platinum.

On April 7, 2016, we received a notice (the First Notice) from CRG, pursuant to the CRG Loan Agreement.  The First Notice claims that Events of Default have occurred under Sections 11.01(m) (alleging that a Change of Control has occurred), 11.01(e) (alleging that the Company’s agreement with Platinum reported in the Company’s Current Report on Form 8-K filed on March 18, 2016 constituted an amendment, modification, waiver or supplement to the Loan Agreement, dated July 25, 2012, between the Company and Platinum that required the written consent of CRG and that a subsidiary of the Company opened a bank account without notifying CRG), and 11.01(d) (alleging that the failure by the Company to notify CRG of a Default itself constitutes an Event of Default) of the Loan Agreement.  The Company also learned that CRG filed an Original Petition (the Petition) in the District Court for Harris County, Texas alleging the same Events of Default as set forth in the Notice and seeking an undetermined amount of damages and a declaratory judgment that the Company is in default under the Loan Agreement and that CRG, as a result, is entitled to the remedies set forth in Section 11.02 of the Loan Agreement.  In the First Notice, CRG indicated that it elected not to require the amounts due under the CRG Loan Agreement to be immediately due and payable, but claimed that the Obligations under the CRG Loan Agreement shall accrue interest at the default rate of 18% per annum until paid in full.

We did not achieve the 2015 annual Lymphoseek sales revenue target of $11 million as initially established under the CRG Loan Agreement, but in December 2015 CRG agreed to a reduction of that target to $10 million (Amendment 1) and we were able to meet that reduced target with Lymphoseek sales revenue of $10.3 million, thereby complying with the covenant.  On April 22, 2016 we received an additional notice (the Second Notice) from CRG, pursuant to the CRG Loan Agreement.  The Second Notice claims that Amendment 1 is invalid due to the existence of Events of Default at the time of its execution in December 2015 which were not disclosed to CRG at that time.  Consequently, CRG claimed that the Company failed to satisfy Section 3(b) of Amendment 1 in order for Amendment 1 to become effective and breached Section 4(a)(iii) of Amendment 1, and as such, Amendment 1 is of no effect and the Company is bound by the 2015 annual Lymphoseek sales revenue target of $11 million as originally set forth in the CRG Loan Agreement.  Since the Company’ 2015 Lymphoseek sales revenue was $10.3 million, the Second Notice claims that an additional Event of Default has occurred under Section 11.01(d) of the CRG Loan Agreement.

On April 28, 2016, the Company received a further notice (the Third Notice) from CRG informing the Company that CRG commenced exercising its remedies, including with respect to cash collateral.  In that regard, CRG informed the Company that it had delivered notices to exercise control of the Company’s accounts pursuant to the blocked account control and pledge collateral account control agreements with CRG.  On May 2, 2016, the Company successfully sought a temporary restraining order in Harris County Court, Texas, in which the court enjoined CRG from causing any further “freeze” of the Company’s accounts and required CRG to restore the accounts to the position they were in prior to CRG’s April 28, 2016 acts, pending a more complete review of the Company’s and CRG’s positions in the lawsuit in a hearing scheduled for May 19, 2016.

The Company is maintaining its position that the alleged claims do not constitute Events of Default under the CRG Loan Agreement and intends to vigorously defend against these claims.  The Company continues to evaluate its options, including the possible assertion of counterclaims.  However, if the Company does not prevail in these legal proceedings, CRG may invoke any and all remedies available to it under the loan agreement and the related security agreement, including acceleration of the maturity of our indebtedness, which could materially adversely affect our ability to continue as a going concern.

Based on CRG’s claims that the Company is in default under the terms of the CRG Loan Agreement, and in accordance with current accounting guidance, the Company has classified the net balance of the CRG Term Loan as a current liability as of March 31, 2016.
