and between _______________________ ("STOCKHOLDER") and Triangle
Pharmaceuticals, Inc., a Delaware corporation (the "COMPANY").

      WHEREAS, Stockholder owns, as of the date hereof, the number of shares of
the Company's Common Stock, $.001 par value per share (the "COMMON STOCK"), set
forth opposite its name on the signature page hereto (such shares of Common
Stock, together with any shares of Common Stock acquired after the date hereof
and prior to the termination hereof, hereinafter collectively referred to as the
"SHARES");

      WHEREAS, concurrently herewith, the Company is entering into one or more
Purchase Agreements (the "PURCHASE AGREEMENT"), which provides for, among other
things, the sale by the Company to one or more investors of shares of Common
Stock having an aggregate purchase price of up to $75,000,000 (the "FINANCING");

      WHEREAS, the Purchase Agreement contemplates that the Financing shall
occur in two tranches (the first tranche referred to hereinafter as the "FIRST
TRANCHE"; the second tranche referred to hereinafter as the "SECOND TRANCHE";
and collectively referred to as the "TRANCHES");

      WHEREAS, the sale and issuance of the shares of Common Stock in the Second
Tranche may require that the Company's stockholders (i) approve an increase in
the number of authorized shares of the Common Stock and (ii) because the Second
Tranche may result in the issuance of shares of Common Stock greater than twenty
percent (20%) of the outstanding shares of capital stock of the Company, approve
the sale and issuance of the shares of Common Stock in the Second Tranche
pursuant to rules established by the National Association of Security Dealers
(the "NASD");

      WHEREAS, it is a condition precedent to closing the First Tranche that the
Company enter into this Agreement with the Stockholder; and

      WHEREAS, the Stockholder will benefit from these transactions and,
therefore, the Stockholder desires to facilitate these transactions by entering
into this Agreement;

      NOW THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, and intending to be
legally bound hereby, the parties agree as follows:

issuance and sale of the shares of Common Stock in the Second Tranche as may be
required by the rules enacted by NASD which are applicable to the Financing and
the Company, and (iii) any other actions related to (i) and (ii), and against

stockholders of the Company, and any adjournment, postponement or continuation
thereof, at which the Financing and other related arrangements or such other
