Exhibit 10.17


                          VALERA PHARMACEUTICALS, INC.


                      series B convertible preferred stock


                         Stock PURCHASE Option AGREEMENT


         This Stock Purchase Option Agreement (this "Agreement") is made and
entered into as of June __, 2004, by and among Pequot Scout Fund, L.P.
("Scout"), Pequot Navigator Fund, L.P. ("Navigator"), GP Strategies Corporation,
a Delaware corporation ("GP Strategies"), National Patent Development
Corporation, a Delaware corporation ("NPDC"), Valera Pharmaceuticals, Inc.
(f/k/a Hydro Med Sciences Inc.), a Delaware corporation (the "Company"), and
each of the persons and entities listed on Exhibit A hereto (collectively with
Scout and Navigator, the "Stockholders").

                                    RECITALS

         The Stockholders are the holders of all of the outstanding shares of
preferred stock (the "Preferred Stock") of the Company, and GP Strategies is the
holder of all of the outstanding shares of common stock (the "Common Stock") of
the Company.

         NPDC is currently a wholly-owned subsidiary of GP Strategies, which GP
Strategies contemplates spinning off to the stockholders of GP Strategies.

         GP Strategies had an option to purchase shares of Series B-1
Convertible Preferred Stock from the Company, which GP Strategies assigned to
Scout and Navigator (the "Assignment"). The Company and Scout and Navigator have
agreed to amend the option to be an option to purchase shares of Series B
Convertible Preferred Stock (the "Option Amendment").

         Scout and Navigator exercised such option and have today purchased from
the Company (the "Initial Purchase") a total of 3,448,276 shares (the "Shares")
of Series B Convertible Preferred Stock of the Company, and Scout and Navigator
have agreed to grant an option to purchase a portion of the Shares to NPDC, and
if NPDC does not exercise such option in full, to the Stockholders, on the terms
and conditions set forth herein.

                                    AGREEMENT

         In consideration of the foregoing recitals and the mutual promises,
representations, warranties and covenants hereinafter set forth and for other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, intending to be legally bound hereby, the parties hereto agree as
follows:




1.       OPTION TO PURCHASE.

1.1 Subject to the terms and conditions hereof, NPDC shall have the option to
  purchase from Scout up to 1,329,596 Shares and from Navigator 739,370 Shares
  (the "Option Shares") at a purchase price of (a) $0.725 per Option Share
  during the period commencing on the date hereof and ending on July 28, 2004,
  (b) $0.7395 per Option Share during the period commencing on July 29, 2004 and
  ending on August 28, 2004, (c) $0.754 per Option Share during the period
  commencing on August 29, 2004 and ending on September 28, 2004, and (d)
  $0.7685 per Option Share during the period commencing on September 29, 2004
  and ending on October 28, 2004. To exercise the option, NPDC must give notice
  (the "NPDC Notice") to Scout and Navigator on or before October 28, 2004
  stating the number of Option Shares with respect to which the option is being
  exercised.

1.2 Promptly after October 28, 2004, Scout and Navigator shall give notice (the
  "Pequot Notice") to the Stockholders stating whether the option was exercised
  by NPDC and, if it was, stating the number of Option Shares with respect to
  which the option was exercised. If NPDC did not exercise the option in full,
  each Stockholder shall have the option to purchase some or all of the Option
  Shares not purchased by NPDC (the "Remaining Shares") at a purchase price of
  $0.7685 per Remaining Share. Each Stockholder desiring to exercise its option
  to purchase some or all of the Remaining Shares must, within the 20-day period
  (the "Stockholder Option Period") commencing on the date the Pequot Notice is
  given, give written notice to Scout and Navigator of such Stockholder's
  election to purchase Remaining Shares, and the number of Remaining Shares that
  such Stockholder desires to purchase. If the total number of Remaining Shares
  specified in the elections of the Stockholders exceeds the number of Remaining
  Shares, then (unless the electing Stockholders otherwise agree in writing)
  each Stockholder electing to purchase will have the right to purchase that
  number of Remaining Shares that is obtained by multiplying the number of
  Remaining Shares by a fraction (A) the numerator of which will be the number
  of shares of Preferred Stock then held by such Stockholder and (B) the
  denominator of which will be the sum of the total number of shares of
  Preferred Stock then held by all Stockholders electing to purchase Remaining
  Shares.

2.       CLOSINGS, DELIVERY AND PAYMENT.

2.1 Closing. The closing of the purchase by NPDC of Option Shares pursuant to
  Section 1.1 shall take place at 9:00 a.m. on the third business day after the
  date the NPDC Notice is given, at 380 Lexington Ave., New York, New York, or
  at such other time or place as GP Strategies and Scout and Navigator may
  mutually agree. The closing of the purchase by the Stockholders of Remaining
  Shares pursuant to Section 1.2 shall take place at 9:00 a.m. on the third
  business day after the end of the Stockholder Option Period, at 380 Lexington
  Ave., New York, New York, or at such other time or place as the Stockholders
  and Scout and Navigator may mutually agree. Each such closing is referred to
  herein as a "Closing."

2.2 Delivery at Closing. At each Closing, subject to the terms and conditions
  hereof, Scout and Navigator will deliver to each purchaser a certificate
  representing the purchased Option Shares registered in the name of the



  purchaser, against payment by the purchaser to Scout and Navigator of the
  purchase price by wire transfer of immediately available funds.

3. REPRESENTATIONS AND WARRANTIES OF GP STRATEGIES, NPDC, AND THE STOCKHOLDERS.

                  Each of GP Strategies (as to Section 3.1 only), NPDC, and each
Stockholder hereby represents and warrants to Scout and Navigator (as to itself
only) as follows:

3.1 Requisite Power and Authority. It has all necessary power and authority to
  execute and deliver this Agreement and to carry out its provisions. All action
  on its part required for the lawful execution and delivery of this Agreement
  has been or will be effectively taken prior to the relevant Closing. This
  Agreement is its valid and binding obligation, enforceable against it in
  accordance with its terms, except (a) as limited by applicable bankruptcy,
  insolvency, reorganization, moratorium or other laws of general application
  affecting enforcement of creditors' rights and (b) as limited by general
  principles of equity that restrict the availability of equitable remedies.

3.2 Investment Representations. It understands that none of the Option Shares or
  the shares of Common Stock issuable upon conversion of the Option Shares (the
  "Conversion Shares") has been registered under the Securities Act of 1933, as
  amended (the "Securities Act"). It also understands that the Option Shares are
  being offered and sold pursuant to an exemption from registration contained in
  the Securities Act based in part upon its representations contained in this
  Agreement. It hereby represents and warrants as follows:

(a) Economic Risk. It has substantial experience in evaluating and investing in
private placement transactions of securities in companies similar to the Company
so that it is capable of evaluating the merits and risks of its investment in
the Company and has the capacity to protect its own interests. If it elects to
exercise its option to purchase Option Shares, it must bear the economic risk of
this investment indefinitely unless the Option Shares (or the Conversion Shares)
are registered pursuant to the Securities Act, or an exemption from registration
is available. It understands that the Company has no present intention of
registering the Option Shares, the Conversion Shares, or any shares of its
Common Stock. It also understands that there is no assurance that any exemption
from registration under the Securities Act will be available and that, even if
available, such exemption may not allow it to transfer all or any portion of the
Option Shares or the Conversion Shares under the circumstances, in the amounts
or at the times it might propose.

(b) Acquisition for Own Account. If it elects to exercise its option to purchase
Option Shares, it is acquiring the Option Shares and the Conversion Shares for
its own account for investment only, and not with a view towards their
distribution.

(c) It Can Protect Its Interest. It represents that by reason of its, or of its
management's, business or financial experience, it has the capacity to protect
its own interests in connection with the transactions contemplated in this
Agreement. Further, it is aware of no publication of any advertisement in
connection with the transactions contemplated in the Agreement.




(d) Accredited Investor. It represents that it is an "accredited investor"
within the meaning of Regulation D under the Securities Act.

(e) Company Information. It has received and read all information it has deemed
necessary or appropriate for purposes of considering its investment hereunder.

(f) Rule 144. If it elects to exercise its option to purchase Option Shares, it
acknowledges and agrees that the Option Shares, and, if issued, the Conversion
Shares must be held indefinitely unless they are subsequently registered under
the Securities Act or an exemption from such registration is available. It has
been advised or is aware of the provisions of Rule 144 promulgated under the
Securities Act as in effect from time to time, which permits limited resale of
shares purchased in a private placement subject to the satisfaction of certain
conditions, including, among other things: the availability of certain current
public information about the Company, the resale occurring following the
required holding period under Rule 144 and the number of shares being sold
during any three-month period not exceeding specified limitations.

3.3 Transfer Restrictions. If it elects to exercise its option to purchase
  Option Shares, it acknowledges and agrees that the Option Shares and, if
  issued, the Conversion Shares are subject to restrictions on transfer as set
  forth in the Amended and Restated Investor Rights Agreement, dated May 30,
  2003, among the Company and its stockholders (the "Investor Rights
  Agreement"), and the Amended and Restated Right of First Refusal and Co-Sale
  Agreement, dated May 30, 2003, among the Company and its stockholders (the
  "Right of First Refusal and Co-Sale Agreement").

4.       REPRESENTATIONS AND WARRANTIES OF SCOUT AND NAVIGATOR.

                  Scout and Navigator hereby represents and warrants to GP
Strategies, NPDC, and the Stockholders as follows:

4.1 Requisite Power and Authority. Scout and Navigator have all necessary power
  and authority to execute and deliver this Agreement and to carry out its
  provisions. All action on its part required for the lawful execution and
  delivery of this Agreement has been or will be effectively taken prior to the
  Closing. This Agreement is the valid and binding obligation of Scout and
  Navigator, enforceable against it in accordance with its terms, except (a) as
  limited by applicable bankruptcy, insolvency, reorganization, moratorium or
  other laws of general application affecting enforcement of creditors' rights
  and (b) as limited by general principles of equity that restrict the
  availability of equitable remedies.

4.2 Title. Scout and Navigator beneficially own and have the unrestricted right
  (other than as such right may be restricted by the Securities Act, the Amended
  and Restated Investor Rights Agreement, and the Amended and Restated Right of
  First Refusal and Co-Sale Agreement) to transfer the Option Shares pursuant to
  this Agreement and, upon purchase of the Option Shares pursuant to this
  Agreement, the purchaser will have good title to the purchased Option Shares,
  free and clear of all liens, security interests, pledges, stockholder
  agreements, voting trusts, claims, charges and other encumbrances, other than
  the Investor Rights Agreement and the Right of First Refusal and Co-Sale
  Agreement.




5.       CONSENT.

6.4 Severability. In case any provision of the Agreement shall be invalid,
  illegal or unenforceable, the validity, legality and enforceability of the
  remaining provisions shall not in any way be affected or impaired thereby.
