      9, 2013&lt;/font&gt;&lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;,

      the Company entered into a note purchase agreement to

      purchase, at par, $3 million of a total $100 million

      aggregate principal amount offering of a Senior Secured notes

      at a price at or above par, as defined.&amp;#160; The Notes are

      secured by certain royalty and milestone payments associated

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;On

      August 8, 2013, the Company entered into a credit agreement

      pursuant to which the Company provided to Tribute

      Pharmaceuticals Canada Inc. ("Tribute") a term loan in the

      principal amount of $8,000,000.&lt;/font&gt; &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;The

      loan matures on August 8, 2018. The Company initially

      provided $6,000,000 at closing. Tribute can draw down the

      remaining $2,000,000 of the credit facility at any time until

      December 31, 2014, as long as it is in compliance&amp;#160;with

      all&amp;#160;covenants under the credit agreement.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: justify; LINE-HEIGHT: 1.25; TEXT-INDENT: 31.5pt; MARGIN: 0pt" id="PARA4370"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;Interest

      and principal under the loan will be paid by a tiered revenue

      interest that is charged on quarterly net sales and royalties

      of the borrower applied in the following priority first, to

      the payment of all accrued but unpaid interest until paid in

      full; second to the payment of all principal of the

      loans.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: justify; LINE-HEIGHT: 1.25; TEXT-INDENT: 31.5pt; MARGIN: 0pt" id="PARA4372"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;The

      loan shall accrue interest at the LIBOR rate, plus an

      applicable margin, subject to a 13.5% minimum.&amp;#160;In

      addition, the Company earned an origination fee at closing,

      and the Company is entitled to an exit fee upon the maturity

      of the loan, both of which will be accreted to interest

      income over the term of the loan. In connection with the

      loan, Tribute also issued the Company 755,736 common share

      purchase warrants with each warrant entitling the Company to

      acquire one common share in&amp;#160;the capital of Tribute

      at&amp;#160;an exercise price of US$0.60, at any time prior to

      August 8, 2020. &amp;#160;&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: justify; LINE-HEIGHT: 1.25; TEXT-INDENT: 31.5pt; MARGIN: 0pt" id="PARA4374"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;In

      the event of a change of control, a merger or a sale of all

      or substantially all of the borrower&amp;#8217;s assets, the loan

      shall be due and payable. The Company will be entitled to

      certain additional payments in connection with repayments of

      the Loan, both on maturity and in connection with a

      prepayment or partial prepayment.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: justify; LINE-HEIGHT: 1.25; TEXT-INDENT: 31.5pt; MARGIN: 0pt" id="PARA4376"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;Pursuant

      to the terms of the credit agreement, Tribute entered into a

      guaranty and collateral agreement granting the Company a

      security interest in substantially all of Tribute&amp;#8217;s

      assets. The credit agreement contains certain affirmative and

      negative covenants. The obligations under the credit

      agreement to repay the loan may be accelerated upon the

      occurrence of an event of default under the credit

      agreement.&lt;/font&gt;
